Technical Field
[0001] The present disclosure relates to the technical field of air conditioning, in particular
to an air conditioner.
Background Art
[0002] The air conditioner refers to a device that uses manual means to adjust and control
parameters of ambient air in buildings or architectures, such as temperature, humidity,
and flow rate. The air conditioners are mostly provided with an air deflector. The
air deflector is connected to a driving box of the air conditioner, so as to drive
the air deflector to rotate to form different opening angles.
[0003] At present, for a casing of an indoor unit of an air conditioner on the market, a
structure for installing the air deflector is provided inside an air outlet, so that
in practical applications, a rotation process of the air deflector is invisible, and
after sending an instruction for adjusting an angle of the air deflector through a
remote controller, a user needs to judge whether the angle of the air deflector is
adjusted in place through feeling of skin about the outgoing air coming out, which
is quite inconvenient. Moreover, since the structure of the casing for installing
the air deflector is provided inside the air outlet, after being installed, the air
deflector cannot be tightly fitted with an outer surface of the casing, and there
is a relatively large gap, then in an actual operation process, the outgoing air is
likely to flow through the gap between the air deflector and the outer surface of
the casing and condenses.
[0004] In addition, when the air conditioner supplies air, air having undergone heat exchange
is usually blown by a wind wheel from the air outlet into room. In a heating mode,
hot air is blown out from the air outlet of the air conditioner, and due to relatively
small density of the hot air, the hot air is easy to directly float to an upper space
in the room after leaving the air outlet, and can hardly reach the ground. In this
way, it is easy to cause the problem of uneven distribution of cold and hot when the
air conditioner is used for heating, and users' comfort is reduced.
[0005] Besides, in the prior art, in the rotation process of the air deflector, the air
deflector will collide with the casing, thus causing wear, damage, and abnormal noises
of the air deflector.
Summary
[0006] In order to solve the above problems existing in the prior art, the present disclosure
provides an air conditioner, including a casing and an air deflector, wherein the
casing is provided with an air outlet, an assembly groove is recessed on an outer
wall of the casing, the assembly groove is provided with a rotation region, the air
deflector includes a mounting part and an air guiding part, wherein the air guiding
part is connected to the mounting part, for guiding an air outlet direction of the
air outlet, and the mounting part is connected in the assembly groove, so that the
air deflector is rotatably connected to the outside of the air outlet of the casing
in the rotation region provided for the assembly groove. In the rotation region corresponding
to the assembly groove, the air deflector can be driven by other driving devices to
rotate back and forth, and also can stay at any position in the rotation region. Since
the air deflector is mounted in the assembly groove on the outer wall of the casing,
the whole air deflector is within a visible range of users, thus a rotation process
of the air deflector is visualized.
[0007] Optionally, the assembly groove is located above the outside of the air outlet, and
is parallel to a length direction of the air outlet. As the assembly groove is located
above the air outlet, after the air deflector is mounted in the assembly groove, when
the air conditioner is heating, hot air blown out from the air outlet can flow under
the guidance of the air deflector, and being blocked by the air deflector, hot air
blown out from the air outlet will not directly float upwards to the upper space after
leaving the air outlet, thereby improving the heating uniformity degree of the upper
space and the lower space, further improving the heating effect of the air conditioner,
and enhancing the user's using comfort. When the air conditioner is cooling, no matter
for a vertical air conditioner or a hanging air conditioner, as the air outlet of
the indoor unit is arranged at a relatively high place in the room, when the air deflector
has a relatively large opening angle, under the guidance of the air deflector, cold
air blown out from the air outlet will not directly flow downwards to the lower space
after leaving the air outlet, thus promoting a cooling uniformity degree of the upper
space and the lower space, further improving cooling effect of the air conditioner,
and enhancing the user's using comfort.
[0008] Optionally, the assembly groove is joined with an upper edge of the air outlet. The
longer a distance between the assembly groove and the air outlet is, the lower the
utilization rate of air guiding effect of the air deflector is. By joining the assembly
groove with the upper edge of the air outlet, the utilization rate of the air deflector
can be maximized, thus avoiding a too large dimension of the air deflector, and saving
the production costs. The assembly groove is parallel to an extending direction of
the air outlet. In an actual operation process, each part of the air deflector connected
to the assembly groove can have the air guiding effect, thus further improving the
utilization rate of the air deflector.
[0009] In an optional embodiment, the assembly groove extends along a horizontal direction.
By making the assembly groove extend along the horizontal direction, that is, the
upper edge of the air outlet also extends along the horizontal direction, an aesthetic
degree after the air deflector is assembled is improved.
[0010] Optionally, a cross section of the mounting part is in an arc shape, and a cross
section of the assembly groove is adapted to the mounting part, so that the mounting
part and the assembly groove are arranged concentrically, and a gap between the mounting
part and the assembly groove is as small as possible, thus preventing condensation
on the outer wall of the casing.
[0011] In an optional embodiment, the assembly groove has one end opened on an end wall
of one end of the casing in the horizontal direction, and the other end extending
to an end wall of the other end of the casing in the horizontal direction. The two
ends of the assembly groove are respectively located on the end walls of the two ends
of the casing in the horizontal direction, i.e., the assembly groove penetrates through
the casing in the horizontal direction, ensuring that after the air deflector is mounted
in the assembly groove, the air deflector can be completely and tightly fitted with
the outer wall of the casing in the horizontal direction, thus avoiding generation
of a blank area and a too big gap, and improving anti-condensation effect.
[0012] In an optional embodiment, a recessed region is recessed on the outer wall of the
casing, the air outlet is opened in the recessed region, and the recessed region is
configured to be fitted with the air deflector. In a power-off state, the air deflector
is embedded into the recessed region to realize fitting with the recessed region,
realize storage of the air deflector, prevent the air deflector from protruding from
the outer wall of the casing in the power-off state, and improve the aesthetic degree.
[0013] In an optional embodiment, the indoor unit includes the casing and a panel provided
on the casing, the recessed region is recessed on the casing, and the assembly groove
is recessed on an outer wall of the panel or the casing.
[0014] Optionally, the air deflector includes an outer plate and an inner lining plate,
the inner lining plate and the outer plate are stacked and spliced, wherein there
is a gap between the outer plate and the inner lining plate, and the inner lining
plate is configured to guide airflow blown out from the air outlet of the air conditioner,
and the outer plate can be configured to decorate and strengthen structural strength
of the air deflector.
[0015] Optionally, the outer plate includes a first arc plate, the inner lining plate includes
a second arc plate, the first arc plate is connected to the second arc plate, and
the first arc plate and the second arc plate are spliced to form the mounting part.
When the outer plate and the inner lining plate are stacked and spliced, the first
arc plate and the second arc plate can be spliced to form the mounting part, wherein
the mounting part with a relatively large arc does not need to be molded independently,
and the arc is separately molded on the outer plate and the inner lining plate respectively,
which can reduce the manufacturing difficulty of the mounting part, and meanwhile
ensure a simple structure of the air deflector for processing and assembling. In an
optional embodiment, the mounting part is of a hollow structure, so that the strength
of the mounting part is not affected while the material is saved, and output required
by the driving device can be reduced.
[0016] In an optional embodiment, a circle center of the first arc plate is coincident with
a circle center of the second arc plate, and a radius of the first arc plate is equal
to a radius of the second arc plate. By configuring the first arc plate and the second
arc plate to have the same radius and have coincident centers, structural regularity
of the mounting part formed by splicing the first arc plate and the second arc plate
can be ensured, and smoothness of rotation of the air deflector is further ensured.
In an optional embodiment, an arc length of the first arc plate is greater than an
arc length of the second arc plate.
[0017] In an optional embodiment, the inner lining plate further includes an air guiding
lining plate, wherein one end of the air guiding lining plate is connected to one
end of the second arc plate not connected to the first arc plate, and the other end
of the air guiding lining plate is connected to the outer plate, and wherein the air
guiding lining plate includes a third arc plate and a fourth arc plate that are connected
in sequence, wherein one end of the third arc plate away from the fourth arc plate
is connected to one end of the second arc plate not connected to the first arc plate,
one end of the fourth arc plate away from the third arc plate is connected to the
outer plate, a side surface of the third arc plate facing away from the outer plate
is a concave surface, and a side surface of the fourth arc plate facing away from
the outer plate is a convex surface, so that an air guiding surface of the air guiding
lining plate is substantially S-shaped. When the air conditioner heating, the hot
air blown out from the air outlet can flow under the guidance of the air guiding lining
plate, and being blocked by the air guiding surface of the air guiding lining plate,
the hot air blown out from the air outlet will not directly float upwards to the upper
space after leaving the air outlet, thus promoting the heating uniformity degree of
the upper space and the lower space, further improving the heating effect of the air
conditioner, and enhancing the user's using comfort. When the air conditioner is cooling,
no matter for a vertical air conditioner or a hanging air conditioner, as the air
outlet of the indoor unit is arranged at a relatively high place in the room, when
the air deflector has a relatively large opening angle, under the guidance of the
air guiding lining plate, cold air blown out from the air outlet will not directly
flow downwards to the lower space after leaving the air outlet, thus promoting a cooling
uniformity degree of the upper space and the lower space, further improving cooling
effect of the air conditioner, and enhancing the user's using comfort.
[0018] In an optional embodiment, the air guiding lining plate is a straight plate or an
arc plate or an arc-shaped plate. By providing the air guiding lining plate as a straight
plate or an arc-shaped plate, the hot air leaving the air outlet can be reliably blocked
from floating upwards.
[0019] Optionally, one end of the outer plate is provided with one of a first clamping portion
and a first fitting portion, an end corresponding to the inner lining plate is provided
with the other one of the first clamping portion and the first fitting portion, and
the first clamping portion is in clamp-fitting with the first fitting portion; the
other end of the outer plate is provided with one of a second clamping portion and
a second fitting portion, an end corresponding to the inner lining plate is provided
with the other one of the second clamping portion and the second fitting portion,
and the second clamping portion is in clamp-fitting with the second fitting portion.
Through the clamp-fitting between the first clamping portion and the second fitting
portion, the assembling of the air deflector is facilitated.
[0020] Optionally, the air deflector includes a first position and a second position, wherein
the first position and the second position are two limiting positions of rotation
of the air deflector in the rotation region configured for the assembly groove; the
casing is provided with a limiting portion, the limiting portion includes a first
wall surface and a second wall surface, and the air deflector is provided with a fitting
portion, wherein when the air deflector is at the first position, the fitting portion
abuts against the first wall surface, and when the air deflector is at the second
position, the fitting portion abuts against the second wall surface. When the air
deflector is located at the first position, through the abutment of the fitting portion
against the first wall surface of the limiting portion, the air deflector, when at
the first position, is limited from colliding with the casing. When the air deflector
is located at the second position, through the abutment of the fitting portion against
the second wall surface of the limiting portion, the air deflector, when at the second
position, is limited from collision and wear with the casing. By providing the limiting
portion on the casing and providing the fitting portion on the air deflector, the
limiting positions of the air deflector are limited through the fitting between the
limiting portion and the fitting portion, thus avoiding collision and wear of the
air deflector with the casing, and solving the problem of damage and abnormal noises
of the air deflector.
[0021] Optionally, the fitting portion has a third wall surface and a fourth wall surface,
wherein when the air deflector is at the first position, the third wall surface abuts
against the first wall surface, and when the air deflector is at the second position,
the fourth wall surface abuts against the second wall surface. When the air deflector
is at the first position, through the abutment of the third wall surface of the fitting
portion against the first wall surface of the limiting portion, the limiting effect
of the air deflector when at the first position can be better improved. When the air
deflector is at the second position, through the abutment of the fourth wall surface
of the fitting portion against the second wall surface of the limiting portion, the
limiting effect of the air deflector when at the second position can be better improved.
[0022] Optionally, the limiting portion is protruded from a bottom wall of the assembly
groove, and the fitting portion is protruded from the air deflector. By making the
limiting portion protruded from the bottom wall of the assembly groove, a better fitting
with the fitting portion can be achieved, and by making the fitting portion protruded,
the fitting portion and the limiting portion can be better fitted, which also facilitates
the molding.
[0023] Optionally, two limiting portions are provided, wherein the two limiting portions
are respectively protruded from two ends of the assembly groove, and two mounting
parts are provided, wherein the two mounting parts are respectively provided at two
ends of the air deflector, and the two limiting portions are respectively fitted with
the fitting portions on the two mounting parts. Through providing the limiting portions
respectively at two ends of the assembly groove to be fitted with the fitting portions
at the two ends of the air deflector, the two sides of the air deflector can be stressed
uniformly, thus avoiding deformation of the air deflector.
[0024] Optionally, the limiting portion is provided with a through groove, wherein the air
deflector is rotatably mounted in the through groove, and the fitting portion is protruded
from a side wall of the mounting part. By providing the through groove on the limiting
portion, the mounting part can easily pass through, and the mounting part can be pre-positioned
through the through groove. By making the fitting portion protruded from the side
wall of the mounting part, the fitting between the fitting portion and the limiting
portion is facilitated
[0025] Optionally, the mounting part includes a first segment and a second segment connected
with each other, wherein the first segment is connected to the air deflector, the
fitting portion is protruded from a side wall of the second segment, the through groove
includes a first groove segment and a second groove segment, and the first wall surface
and the second wall surface are both connected to a side wall of the second groove
segment, wherein the first segment is mounted in the first groove segment, and the
second segment is mounted in the second groove segment; the third wall surface and
the fourth wall surface are two opposite side walls of the fitting portion, and the
first wall surface and the second wall surface are respectively located at two sides
of the second groove segment. By providing the first side wall and the second side
wall at two sides of the second groove segment, it facilitates better abutment of
the fitting portion. By providing the fitting between the first segment and the first
groove segment, the mounting part can be pre-positioned when mounting the mounting
part. By providing the second segment, and making the fitting portion protruded from
the side wall of the second segment, it facilitates the abutment of the fitting portion
against the first wall surface and the second wall surface in the rotation process.
By providing the first wall surface and the second wall surface at two sides of the
second groove segment, it facilitates the abutment of the first wall surface against
the third wall surface and the abutment of the second wall surface against the fourth
wall surface.
[0026] Optionally, the first segment is clearance-assembled in the first groove segment,
and the second segment is clearance-assembled in the second groove segment. Through
the clearance-assembling of the first segment with the first groove segment, friction
of the first segment with the side wall of the first groove segment is reduced in
the rotation process, so as to reduce the wear of the first segment or the first groove
segment. Through the clearance-assembling of the second segment with the second groove
segment, friction of the second segment with the side wall of the second groove segment
is reduced in the rotation process, so as to reduce the wear of the second segment
or the second groove segment
[0027] Optionally, a diameter of the first segment is greater than a diameter of the second
segment, and a diameter of the first groove segment is greater than a diameter of
the second groove segment. By making the diameter of the first segment greater than
the diameter of the second segment, and the diameter of the second groove segment
greater than the diameter of the first groove segment, fitting between an end surface
of the first segment and an end surface of the first groove segment can limit a mounting
position of the mounting part, which realizes pre-positioning of the mounting part
in the process of mounting of the mounting part.
[0028] Optionally, a driving box is further included, the casing is provided with a groove
hole, the driving box is mounted on the casing, and the driving box extends out of
the groove hole to be connected with the air deflector, so as to drive the air deflector
to rotate. By making the driving box extend out of the casing to be connected to the
air deflector, the air deflector can be better assembled.
[0029] Optionally, the outer wall of the casing is further provided with a support member,
and the support member is configured to be rotatably connected to the air deflector,
so as to increase stability of the air deflector when rotating. The support member
functions to support the air deflector, which improves the reliability of the operation
process.
[0030] In the present disclosure, since the air deflector is mounted in the assembly groove
on the outer wall of the casing, the whole air deflector is within the visible range
of users, thus the rotation process of the air deflector is visualized.
[0031] In the present disclosure, the air deflector is connected to the adapted assembly
groove through an arc-shaped part, so that the gap between the mounting part and the
assembly groove is as small as possible, thus preventing condensation on the outer
wall of the casing. Furthermore, two ends of the assembly groove are respectively
located on the end walls of two ends of the casing in the horizontal direction, and
the anti-condensation effect is improved.
[0032] In the present disclosure, in the heating mode, the air deflector is in a position
with a relatively small opening degree, wherein the air deflector has a pressing down
effect on the hot air, and the hot air blown out from the air outlet will not directly
float upwards to the upper space after leaving the air outlet; in the cooling mode,
the air deflector has a relatively large opening degree, and under the guidance of
the air deflector, the cold air blown out from the air outlet will not directly flow
downwards to the lower space after leaving the air outlet. Thus, the cooling uniformity
degree of the upper space and the lower space is promoted, further the cooling effect
of the air conditioner is improved, and the user's using comfort is enhanced.
[0033] In the present disclosure, by providing the limiting portion on the casing and providing
the fitting portion on the air deflector, through the fitting between the limiting
portion and the fitting portion, the limitation to the air deflector is realized,
collision and wear of the air deflector with the casing are avoided, and the problem
of damage or abnormal noises of the air deflector is solved.

Detailed Description of Embodiments
[0036] The present disclosure is further described in detail below with reference to drawings
and embodiments. It can be understood that specific embodiments described herein are
merely used to explain the present disclosure but not to limit the present disclosure.
Besides, it further should be noted that in order to facilitate the description, only
some but not all structures related to the present disclosure are shown in the drawings.
[0037] Referring to FIG. 1, an indoor unit 100 of an air conditioner of the present embodiment
includes a casing 110 and an air deflector 150, the casing 110 is provided with an
air outlet 117, the air outlet 117 is configured to blow air into room, an assembly
groove 119 is recessed on an outer wall of the casing 110, and the assembly groove
119 is configured for the air deflector 150 to be embedded therein and is rotatably
fitted with the air deflector 150, so as to realize installation of the air deflector
150. The air deflector 150 is mounted in the assembly groove 119 so as to be rotatably
connected to the casing 110 in a provided rotation region. In the provided rotation
region, the air deflector 150 can be driven by other driving devices to rotate back
and forth, and also can stay at any position in the rotation region. A specific range
is determined according to actual needs. Since the air deflector 150 is mounted in
the assembly groove 119 on the outer wall of the casing 110, the whole air deflector
150 is within a visible range of users, thus a rotation process of the air deflector
150 is visualized. In practical applications, after the air deflector 150 is mounted
in the assembly groove 119, the rotation process of the air deflector 150 can be easily
observed, thus the rotation process is visualized, and it is convenient for the user
to adjust the angle of the air deflector 150 quickly. It can be understood that, in
practical applications, the air deflector 150 is provided with a driving device, so
as to drive the air deflector 150 to rotate to a plurality of angles, and guide the
air from the air outlet 117 in different directions.
[0038] Referring to FIG. 2, for a casing of the present embodiment, the assembly groove
119 is located above the outside of the air outlet 117, and is parallel to a length
direction of the air outlet 117. After being mounted in the assembly groove 119, the
air deflector 150 is driven by the driving device to rotate in a vertical plane. The
assembly groove 119 is located above the air outlet 117, and after the air deflector
150 is mounted in the assembly groove 119, when the indoor unit 100 to which the casing
110 provided in the present embodiment is applied runs in a heating mode, the air
deflector 150 should be in a position with a relatively small opening degree. Hot
air blown out from the air outlet 117 will immediately float upwards after leaving
the air outlet 117, and the air deflector 150 has a pressing effect on this part of
hot air. Being blocked by the air deflector 150, the hot air blown out from the air
outlet 117 will not directly float upwards to an upper space after leaving the air
outlet 117, thus promoting a heating uniformity degree of the upper space and a lower
space, further improving the heating effect of the air conditioner, and enhancing
the user's using comfort. When the air conditioner is cooling, the air deflector 150
should be in a position with a relatively large opening degree, and no matter for
a vertical air conditioner or a hanging air conditioner, as the air outlet 117 of
the indoor unit 100 is arranged at a relatively high place in the room, when the air
deflector 150 has a relatively large opening degree, under the guidance of the air
deflector 150, cold air blown out from the air outlet 117 will not directly flow downwards
to the lower space after leaving the air outlet 117, thus promoting a cooling uniformity
degree of the upper space and the lower space, further improving cooling effect of
the air conditioner, and enhancing the user's using comfort.
[0039] For the casing 110 provided in the present embodiment, as the assembly groove 119
for mounting the air deflector 150 is provided on the outer wall of the casing 110,
model selection of the air deflector 150 is not limited by a dimension of the air
outlet 117, as long as the air outlet 117 can be completely shielded in a power-off
state. That is, the casing 110 provided in the present embodiment can be provided
with the air deflector 150 of a larger dimension, and further the air guide effect
is significantly improved.
[0040] Referring to FIG. 1 and FIG. 2, in the present embodiment, in order to improve a
utilization rate of the air deflector 150 so as to save production costs, the assembly
groove 119 is joined with an upper edge of the air outlet 117, which can be understood
as that the assembly groove 119 is in communication with the air outlet 117. In cases
where the air deflector 150 is rotatably fitted with the assembly groove 119, a part
of the air deflector 150 close to the assembly groove 119 also can have a flow guiding
effect on the air outlet 117, that is, the utilization rate of the air deflector 150
is improved. The longer a distance between the assembly groove 119 and the air outlet
117 is, the lower the utilization rate of air guiding effect of the air deflector
150 is. By joining the assembly groove 119 with the upper edge of the air outlet 117,
the utilization rate of the air deflector 150 can be maximized, thus avoiding a too
large dimension of the air deflector 150, and saving the production costs. The assembly
groove 119 is parallel to an extending direction of the air outlet 117, and in an
actual operation process, each part of the air deflector 150 connected to the assembly
groove 119 can have the air guiding effect, thus further improving the utilization
rate of the air deflector 150.
[0041] Moreover, considering that the air outlet 117 of most indoor units 100 on the market
has a rectangular structure with long sides extending in the horizontal direction,
in order to be adapted to most indoor units 100 on the market, in the present embodiment,
the assembly groove 119 extends along the horizontal direction, that is, the upper
edge of the air outlet 117 also extends along the horizontal direction. The assembly
groove 119 extends along the horizontal direction, that is, the upper edge of the
air outlet 117 also extends along the horizontal direction, improving aesthetic degree
after the air deflector 150 is assembled.
[0042] Referring to FIG. 3 and FIG. 4, the air deflector 150 includes a mounting part 159
and an air guiding part 157, where the mounting part 159 is configured to be fitted
and mounted with the assembly groove 119, and after the air deflector 150 is mounted
to the assembly groove 119, in order to realize smooth rotation, and further ensure
close fitting of the air deflector 150 to prevent generation of a too big gap, in
the present embodiment, the assembly groove 119 is configured as a semi-cylindrical
groove, i.e., a cross section of the assembly groove 119 is in a semi-arc shape. In
practical applications, corresponding to the structure of the assembly groove 119,
one side of the chosen air deflector 150 needs to be provided with the mounting part
159 in a cylindrical shape, wherein the mounting part 159 is embedded into the assembly
groove 119, and through rotational fitting between the mounting part 159 and the assembly
groove 119, rotational fitting between the air deflector 150 and the casing 110 is
realized. Since the assembly groove 119 is recessed on the outer wall of the casing
110, a connection structure between the air deflector 150 and the casing 110 is prevented
from protruding outwards, thus improving overall aesthetic degree of the casing 110.
Meanwhile, the air deflector 150 is connected to the matched assembly groove 119 through
an arc-shaped part, so that the gap between the mounting part 159 and the assembly
groove 119 is as small as possible, thus preventing condensation on the outer wall
of the casing 110.
[0043] In some embodiments, in order to further ensure the anti-condensation effect, lengths
of the mounting part 159 and the air deflector 150 are both corresponding to the length
of the assembly groove 119. That is, in the case where the mounting part 159 is embedded
into the assembly groove 119, two ends of the mounting part 159 are coplanar with
end walls of the two ends of the assembly groove 119, respectively, and two ends of
the air deflector 150 in the length direction are coplanar with the end walls of the
two ends of the assembly groove 119, respectively.
[0044] Further, the assembly groove 119 has one end opened on an end wall of one end of
the casing 110 in the horizontal direction, and the other end extending to an end
wall of the other end of the casing 110 in the horizontal direction. The two ends
of the assembly groove 119 are respectively located on the end walls of the two ends
of the casing 110 in the horizontal direction, i.e., the assembly groove 119 penetrates
through the casing 110 in the horizontal direction, ensuring that after the air deflector
150 is mounted in the assembly groove 119, the air deflector 150 can be completely
and tightly fitted with the outer wall of the casing 110 in the horizontal direction,
thus avoiding generation of a too big gap in a blank area, and improving the anti-condensation
effect.
[0045] In some embodiments, in order to facilitate transmission connection between the driving
device and the air deflector 150 of the indoor unit 100, the drive device is avoided
from being arranged outside, thus improving concealment and installation. A groove
wall of the assembly groove 119 is opened with a groove hole 127, the driving device
of the indoor unit 100 can be mounted inside the casing 110, and only an output end
thereof extends into the assembly groove 119 through the groove hole 127 and is in
transmission connection with a fitting roller of the air deflector 150, so as to drive
the fitting roller, and realize the rotation of the air deflector 150 in the vertical
plane.
[0046] Referring to FIG. 2, it should be noted that the indoor unit 100 includes the casing
110 and a panel, and the panel is provided on a surface of the casing 110. A recessed
region 172 is recessed on the outer wall of the casing 110, the air outlet 117 is
formed in the recessed region 172, and the recessed region 172 is configured to be
fitted with the air deflector 150. Actually, the indoor unit 100 can receive the air
deflector 150 in a power-off state, that is, the air deflector 150 shields the air
outlet 117 when being embedded into the recessed region 172, so as to prevent the
air deflector 150 from protruding from the surface of the casing 110 in the power-off
state, and improve the aesthetic degree of the indoor unit 100, and moreover, dust
accumulation at the air outlet 117 can be effectively prevented. The assembly groove
119 can be recessed on the outer wall of the casing 110, or can be recessed on an
outer wall of the panel. In the present embodiment, for the sake of facilitating processing,
the assembly groove 119 is recessed on the outer wall of the casing 110.
[0047] The casing 110 provided in the present embodiment, as the assembly groove 119 for
mounting the air deflector 150 is recessed on the outer wall thereof, can be adapted
to air deflectors 150 of more dimensions, without being limited by the dimension of
the air outlet 117, and with mounting of the air deflectors 150 of a larger dimension,
the air guiding effect can be significantly improved. Furthermore, as the assembly
groove 119 is recessed on the outer wall of the casing 110, after fitting of the air
deflector 150 and the assembly groove 119 is completed, the user can clearly observe
the rotation process and the rotation angle of the air deflector 150, so that the
air guide angle of the air deflector 150 can be adjusted in place more quickly. Furthermore,
after the fitting of the air deflector 150 and the assembly groove 119 is completed,
the air deflector 150 is embedded into the outer wall of the casing 110, and is tight
fitted with the outer wall of the casing 110, and prevent generation of a too big
gap, thus avoiding generation of condensation on the outer wall of the casing 110.
[0048] Therefore, the casing 110 provided in the present embodiment can be adapted to the
air deflectors 150 of more dimensions, can realize the visualization of the rotation
process and the rotation angle of the air deflector 150, further has the anti-condensation
effect, and can significantly improve the user experience.
[0049] Referring to FIG. 5, an air deflector 150 of the present embodiment includes an outer
plate 210 and an inner lining plate 220, wherein the inner lining plate 220 and the
outer plate 210 are stacked and spliced, and there is a gap 230 between the outer
plate 210 and the inner lining plate 220, wherein the inner lining plate 220 is configured
to guide airflow blown out from the air outlet 117 of the air conditioner, and the
outer plate 210 can be used to decorate and reinforce structural strength of the air
deflector 150. When the air conditioner is heating, hot air blown out from the air
outlet 117 can flow under the guidance of the inner lining plate 220, and the hot
air blown out from the air outlet 117, under obstruction of the inner lining plate
220, will not directly float upwards to the upper space after leaving the air outlet
117, thereby improving the heating uniformity degree of the upper space and the lower
space, further improving the heating effect of the air conditioner, and enhancing
the user's using comfort.
[0050] Further, the outer plate 210 includes a first arc plate 211, the inner lining plate
220 includes a second arc plate 221, wherein the first arc plate 211 is connected
to the second arc plate 221, and the first arc plate 211 and the second arc plate
221 are spliced to form the mounting part 159. When the outer plate 210 and the inner
lining plate 220 are stacked and spliced, the first arc plate 211 and the second arc
plate 221 can be spliced to form the mounting part 159, and the mounting part 159
with a relatively large arc does not need to be molded independently, wherein the
arc is disassembled and separately molded on the outer plate 210 and the inner lining
plate 220 respectively, which can reduce the manufacturing difficulty of the mounting
part 159, and meanwhile ensure a simple structure of the air deflector 150 for processing
and assembling. In an optional embodiment, the mounting part 159 is of a hollow structure,
so that the strength of the mounting part 159 is not affected while the material is
saved, and output required by the driving device can be reduced. Besides, the hollow
structure facilitates transmission fitting of the air deflector 150 with the driving
device through the hollow structure, and it is further convenient to drive the air
deflector 150 by the driving device to rotate to different operation positions when
the air deflector 150 is used in the air conditioner. For example, an inner side of
the first arc plate 211 is provided with a clamping member, the driving device includes
a driving shaft 171, wherein the driving shaft 171 can extend into the hollow mounting
part 159 and is connected to the clamping member, and when the driving shaft 171 rotates,
the first arc plate 211 can be driven by the driving shaft 171, further driving the
whole air deflector 150 to rotate.
[0051] Referring to FIG. 6, in the present embodiment, the air deflector 150 further includes
a mounting plate 231 and a pivot shaft 232 provided on the mounting plate 231, and
the mounting plate 231 is fixedly connected to one end of the first arc plate 211
in the length direction; the casing 110 is provided with a pivot hole (not shown in
the drawing), and the pivot shaft 232 is in pivot fitting with the pivot hole. Further,
the driving device is in transmission fitting with one end of the air deflector 150
away from the pivot shaft 232; in this way, the air deflector 150 can be reliably
provided on the casing 110, and the air deflector 150 can be driven by the driving
device to reliably rotate, so as to adjust the air guiding direction.
[0052] Further, a circle center of the first arc plate 211 is coincident with a circle center
of the second arc plate 221, and a radius of the first arc plate 211 is equal to a
radius of the second arc plate 221. By configuring the first arc plate 211 and the
second arc plate 221 to have the same radius and have coincident centers, structural
regularity of the mounting part 159 formed by splicing the first arc plate 211 and
the second arc plate 221 can be ensured, and smoothness of rotation of the air deflector
150 is further ensured. Further, an arc length of the first arc plate 211 is greater
than an arc length of the second arc plate 221; in this way, the first arc plate 211
is allowed to have a larger surface area, which is beneficial for the driving device
to achieve transmission connection with the air deflector 150 through the first arc
plate 211. Certainly, in other embodiments, an arc length of the first arc plate 211
is equal to or smaller than an arc length of the second arc plate 221, which is not
specifically limited herein.
[0053] In the present embodiment, the inner lining plate 220 further includes an air guiding
lining plate 222, wherein one end of the air guiding lining plate 222 is connected
to one end of the second arc plate 221 not connected to the first arc plate 211, and
the other end of the air guiding lining plate 222 is connected to the outer plate
210; the air guiding lining plate 222 is configured to guide the airflow blown out
from the air outlet 117 of the air conditioner and block the airflow from floating
upwards. By guiding the airflow blown out from the air outlet 117 of the air conditioner
and preventing the airflow from flowing upwards by the air guiding lining plate 222,
when the air conditioner is heating, the hot air will not directly float upwards to
the upper space after leaving the air outlet 117, thus promoting the heating uniformity
degree of the upper space and the lower space, further improving the heating effect
of the air conditioner, and enhancing the user's using comfort. When the air conditioner
is cooling, no matter for a vertical air conditioner or a hanging air conditioner,
as the air outlet 117 of the indoor unit 100 is arranged at a relatively high place
in the room, when the air deflector 150 has a relatively large opening angle, under
the guidance of the air guiding lining plate 222, cold air blown out from the air
outlet 117 will not directly flow downwards to the lower space after leaving the air
outlet 117, thus promoting a cooling uniformity degree of the upper space and the
lower space, further improving cooling effect of the air conditioner, and enhancing
the user's using comfort. The air guiding lining plate 222 can be shaped according
to needs, and the air guiding lining plate 222 in the present embodiment is an arc-shaped
plate, so as to better guide flow of the airflow blown out from the air outlet 117
with the streamlined air guiding lining plate 222.
[0054] Referring to FIG. 5, the air guiding lining plate 222 further includes a third arc
plate 223 and a fourth arc plate 224 that are connected in sequence, wherein one end
of the third arc plate 223 away from the fourth arc plate 224 is connected to one
end of the second arc plate 221 not connected to the first arc plate 211, and one
end of the fourth arc plate 224 away from the third arc plate 223 is connected to
the outer plate 210, wherein a side surface of the third arc plate 223 facing away
from the outer plate is a concave surface, and a side surface of the fourth arc plate
224 facing away from the outer plate is a convex surface, so that an air guiding surface
of the air guiding lining plate 222 is substantially S-shaped. In this way, not only
the flow of the airflow blown out from the air outlet 117 can be guided, but also
the hot air blown out from the air outlet 117 can be reliably blocked by the air guiding
lining plate 222 from directly floating upwards after leaving the air outlet 117;
certainly, in other embodiments, the substantially S-shaped air guiding lining plate
222 can also reliably block the cold air blown out from the air outlet 117 from directly
moving downwards after leaving the air outlet 117. It should be understood that, in
other embodiments, the air guiding lining plate 222 only includes the third arc plate
223, and the concave surface of the third arc plate 223 faces away from the outer
plate 210. Referring to FIG. 7, in other embodiments, the air guiding lining plate
222 further may be a straight plate, which also can reliably block the hot air leaving
the air outlet 117 from floating upwards or block the cold air leaving the air outlet
117 from flowing downwards.
[0055] It should be noted that, the inner lining plate 220 of the present embodiment can
be integrally molded, that is, the second arc plate 221, the third arc plate 223,
and the fourth arc plate 224 are integrally molded; certainly, in other embodiments,
a connection manner between the second arc plate 221, the third arc plate 223, and
the fourth arc plate 224 also may be bonding or welding, which is not specifically
limited herein.
[0056] In the present embodiment, the outer plate 210 further includes an extension plate
212, wherein the extension plate 212 is connected to one end of the first arc plate
211 not connected to the second arc plate 221, and one end of the extension plate
212 away from the first arc plate 211 is connected to one end of the air guiding lining
plate 222 away from the second arc plate 221, that is, one end of the extension plate
212 away from the first arc plate 211 is connected to one end of the fourth arc plate
224 away from the third arc plate 223, and there is a gap 230 between the extension
plate 212 and the air guiding lining plate 222. A shape of the extension plate 212
can be selected according to needs, for example, it may be an arc-shaped plate, a
straight plate and so on, which is not specifically limited herein. It should be noted
that, a connection manner of the first arc plate 211 and the extension plate 212 can
be selected according to needs, for example, integral molding, welding, or bonding,
which is not specifically limited herein.
[0057] A connection manner of the outer plate 210 and the inner lining plate 220 can be
selected according to needs; a first end of the outer plate 210 in the present embodiment
is provided with a first fitting portion 213, a first end of the inner lining plate
220 is provided with a first clamping portion 225, and the first clamping portion
225 is in clamp-fitting with the first fitting portion 213. In this way, the air deflector
150 is simple to assemble and operate. Certainly, in other embodiments, the first
end of the outer plate 210 is provided with the first clamping portion 225, the first
end of the inner lining plate 220 is provided with the first fitting portion 213,
and the first clamping portion 225 is in clamp-fitting with the first fitting portion
213.
[0058] Further, the first clamping portion 225 is provided on the second arc plate 221,
and the first fitting portion 213 is provided on the first arc plate 211; in this
way, when the first clamping portion 225 is in clamp-fitting with the first fitting
portion 213, the first arc plate 211 and the second arc plate 221 can be reliably
spliced to form the mounting part 159.
[0059] Optionally, the first clamping portion 225 is a clamping hook provided on the second
arc plate 221, the first fitting portion 213 is a groove provided on the first arc
plate 211, and the clamping hook can be in clamping fit with the groove. Certainly,
the first fitting portion 213 may also be a lug, and the clamping hook can be in clamping
fit with the lug.
[0060] In order to further ensure the easy assembling of the outer plate 210 and the inner
lining plate 220, a second end of the outer plate 210 is provided with a second fitting
portion 214, a second end of the inner lining plate 220 is provided with a second
clamping portion 226, and the second clamping portion 226 is in clamp-fitting with
the second fitting portion 214. Through the clamping fit between the second clamping
portion 226 and the second fitting portion 214, it is more convenient to assemble
the air deflector 150. Certainly, in other embodiments, the second end of the outer
plate 210 is provided with the second clamping portion 226, the second end of the
inner lining plate 220 is provided with the second fitting portion 214, and the second
clamping portion 226 is in clamp-fitting with the second fitting portion 214.
[0061] Further, the second clamping portion 226 is provided at one end of the fourth arc
plate 224 away from the third arc plate 223, and the second fitting 214 is provided
at one end of the extension plate 212 away from the first arc plate 211. In this way,
by means of the first clamping portion 225 and the first fitting portion 213 that
are in clamping fit with each other, as well as the second clamping portion 226 and
the second fitting portion 214 that are in clamping fit with each other, the outer
plate 210 and the inner lining plate 220 can be reliably assembled together, so as
to ensure the structural reliability of the air deflector 150.
[0062] Optionally, the second clamping portion 226 is a clamping hook provided on the fourth
arc plate 224, and the second fitting portion 214 is a folded edge provided on the
extension plate 212; specifically, the folded edge is connected to the extension plate
212 at an angle, and there is a clamping slot 215 between the folded edge and the
extension plate 212; the clamping hook as the second clamping portion 226 can be clamped
into the clamping slot 215. In this way, when the air deflector 150 is assembled,
the second clamping portion 226 can be clamped to the clamping slot 215, and then
the first clamping portion 225 can be clamped with the first fitting portion 213,
so that the air deflector 150 is simple to assemble and operate. It should be noted
that the angle between the folded edge and the extension plate 212 may be 20°, 30°,
etc., which is not specifically limited herein.
[0063] It should be understood that, in other embodiments, a connection manner of the first
end of the outer plate 210 and the first end of the inner lining plate 220 also may
be bonding, or connection by a fastener such as a screw, which is not specifically
limited herein; in a similar way, in other embodiments, a connection manner of the
second end of the outer plate 210 and the second end of the inner lining plate 220
also may be bonding, or connection by a fastener such as a screw, which is not specifically
limited herein.
[0064] Referring to FIG. 9 and FIG. 10, in the present embodiment, the air deflector 150
has a first position and a second position, wherein the first position and the second
position are two limiting positions of rotation of the air deflector in the rotation
region configured for the assembly groove. The casing 110 is provided with a limiting
portion 111, and the limiting portion 111 includes a first wall surface 113 and a
second wall surface 115. The air deflector 150 is provided with a fitting portion
151. When the air deflector 150 is at the first position, the fitting portion 151
abuts against the first wall surface 113. When the air deflector 150 is at the second
position, the fitting portion 151 abuts against the second wall surface 115.
[0065] In the present embodiment, by providing the limiting portion 111 on the casing 110
and providing the fitting portion 151 on the air deflector 150, the air deflector
150 is limited through the fitting between the limiting portion 111 and the fitting
portion 151, thus avoiding collision and wear of the air deflector 150 with the casing
110, and solving the problem of damage and abnormal noises of the air deflector 150.
When the air deflector 150 is located at the first position, through the abutment
of the fitting portion 151 against the first wall surface 113 of the limiting portion
111, the air deflector 150 is avoided from collision and wear with the casing 110
when the air deflector 150 is at the first position. When the air deflector 150 is
located at the second position, through the abutment of the fitting portion 151 against
the second wall surface 115 of the limiting portion 111, the air deflector 150 is
avoided from collision and wear with the casing 110 when the air deflector 150 is
at the second position, and solving the problem caused by collision, wear, and abnormal
noises of the air deflector 150 with the casing 110. In the present embodiment, the
first position of the air deflector 150 represents a position where the air deflector
150 is fully opened, and the second position of the air deflector 150 represents a
position where the air deflector 150 is fully closed.
[0066] In some other embodiments of the present disclosure, the first position and the second
position also can represent positions of preset opening degrees of the air deflector
150, for example, the first position can represent a position of the air deflector
150 at 95% opening degree, and the second position can also represent a position of
the air deflector 150 at 1% opening degree. The first position and the second position
can also represent a limiting opening position and a limiting closing position of
the air deflector 150, wherein the limiting opening position and the limiting closing
position are two limiting positions designed for the air deflector 150, and the two
limiting positions are not positions where the air deflector 150 is normally open
and normally closed.
[0067] Referring to FIG. 9 and FIG. 10, in the present embodiment, the fitting portion 151
has a third wall surface 153 and a fourth wall surface 155. When the air deflector
150 is at the first position, the third wall surface 153 abuts against the first wall
surface 113. When the air deflector 150 is at the second position, the fourth wall
surface 155 abuts against the second wall surface 115. When the air deflector 150
is at the first position, through the abutment of the third wall surface 153 of the
fitting portion 151 against the first wall surface 113 of the limiting portion 111,
a contact area between the limiting portion 111 and the fitting portion 151 can be
increased, and thus the limiting effect of the air deflector 150 when at the first
position is better improved. When the air deflector 150 is at the second position,
through the abutment of the fourth wall surface 155 of the fitting portion 151 against
the second wall surface 115 of the limiting portion 111, a contact area between the
limiting portion 111 and the fitting portion 151 can be increased, and thus the limiting
effect of the air deflector 150 when at the second position is better improved.
[0068] In the present embodiment, the limiting portion 111 is protruded from a bottom wall
of the assembly groove 119. By making the limiting portion 111 protruded from the
bottom wall of the assembly groove 119, a better fitting with the fitting portion
151 can be achieved, and the molding of the limiting portion 111 is also facilitated.
In some embodiments of the present disclosure, the limiting portion 111 also can be
recessed on a side wall of the assembly groove 119. When the limiting portion 111
is recessed on the bottom wall of the assembly groove 119, the fitting portion 151
can be protruded from the air deflector 150, and extend into the limiting portion
111 to limit the first position and the second position of the air deflector 150.
In some other embodiments of the present disclosure, the assembly groove 119 also
can be recessed on a side wall of the air outlet 117 or other positions.
[0069] In the present embodiment, the fitting portion 151 is protruded from the air deflector
150. By making the fitting portion 151 protruded from the air deflector 150, the fitting
portion 151 can be better fitted with the limiting portion 111 without reducing the
strength of the air deflector 150. In some other embodiments of the present disclosure,
the fitting portion 151 also can be recessed on the air deflector 150, and when the
air deflector 150 is recessed, the limiting portion 111 can be protruded from the
assembly groove 119, and extend into the fitting portion 151 to limit the first position
and the second position of the air deflector 150, so as to avoid collision of the
air deflector 150 with the casing 110.
[0070] In the present embodiment, two limiting portions 111 are provided, wherein the two
limiting portions 111 are respectively protruded from two ends of the assembly groove
119, and two mounting parts 159 are provided, wherein the two mounting parts 159 are
respectively provided at two ends of the air deflector 150, and the two limiting portions
111 are respectively fitted with the fitting portions 151 on the two mounting parts
159. Through providing the limiting portions 111 at both ends of the assembly groove
119 to be fitted with the fitting portions 151 at the two ends of the air deflector
150, two sides of the air deflector 150 can be stressed uniformly, thus avoiding deformation
of the air deflector 150.
[0071] In some other embodiments of the present disclosure, it is also feasible to provide
one mounting part 159, and the mounting part 159 is provided at one end of the air
deflector 150. The other end of the mounting part 159 can be rotatably mounted in
the assembly groove 119 in a manner such as shaft-hole fitting.
[0072] Referring to FIG. 11 and FIG. 12, in the present embodiment, the limiting portion
111 is provided with a through groove 121, the air deflector 150 is rotatably mounted
in the through groove 121, and the fitting portion 151 is protruded from a side wall
of the mounting part 159. By providing the through groove 121 on the limiting portion
111, it is easy for the mounting part 159 to pass through, and the mounting part 159
can be pre-positioned through the through groove 121. By making the fitting portion
151 protruded from the side wall of the mounting part 159, the fitting between the
fitting portion 151 and the limiting portion 111 is facilitated.
[0073] In the present embodiment, the fitting portion 151 is protruded from the side wall
of the mounting part 159. The third wall surface 153 and the fourth wall surface 155
are two opposite side walls of the fitting portion 151, and the third wall surface
153 and the fourth wall surface 155 are respectively connected to the side wall of
the mounting part 159. The first wall surface 113 and the second wall surface 115
are located at two sides of the through groove 121. Thus, it is more convenient to
provide the first wall surface 113 and the second wall surface 115, and it also can
avoid interference when mounting the air deflector 150.
[0074] In some other embodiments of the present disclosure, the fitting portion 151 also
can be protruded from the end portion of the mounting part 159 and fitted with the
protruded limiting portion 111, so as to limit the first position and the second position
of the air deflector 150. Alternatively, the fitting portion 151 is protruded from
the side wall of the mounting part 159 and fitted with the limiting portion 111 protruded
from the bottom wall of the assembly groove 119, so as to limit the first position
and the second position of the air deflector 150.
[0075] Referring to FIG. 13 and FIG. 14, in the present embodiment, the mounting part 159
includes a first segment 163 and a second segment 165 connected with each other. The
first segment 163 is protruded from the end portion of the mounting part 159. The
fitting portion 151 is protruded from a side wall of the second segment 165. The through
groove 121 includes a first groove segment 123 and a second groove segment 125. The
first wall surface 113 and the second wall surface 115 are located at two sides of
the second groove segment 125 respectively, and both the first wall surface 113 and
the second wall surface 115 are both connected to a side wall of the second groove
segment 125. The first segment 163 is mounted in the first groove segment 123, and
the second segment 165 is mounted in the second groove segment 125. Through providing
the fitting between the first segment 163 and the first groove segment 123, the position
of the air deflector 150 can be pre-positioned when mounting the air deflector 150,
so that an axis of the mounting part 159 is substantially coincident with an axis
of the assembly groove 119, ensuring that the mounting part 159 better rotates in
the assembly groove 119. Meanwhile, mounting accuracy of the fitting portion 151 also
can be ensured, so that position limiting accuracy of the air deflector 150 is higher.
[0076] In the present embodiment, a diameter of the first segment 163 is greater than a
diameter of the second segment 165. A diameter of the first groove segment 123 is

groove segment 123. That is, the diameter of the first segment is slightly smaller
than the diameter of the first groove segment 123, and the length of the first segment
163 is slightly smaller than the length of the first groove segment 123. Through the
clearance-assembling of the first segment 163 with the first groove segment 123, the
first segment 163 will not generate friction with a side wall of the first groove
segment 123 during rotation, thus avoiding wear of the first segment 163 or the first
groove segment 123. The second segment 165 is clearance-assembled in the second groove
segment 125. That is, a diameter of the second segment 165 is slightly smaller than
a diameter of the second segment 125. Through the clearance-assembling of the second
segment 165 with the second groove segment 125, the second segment 165 will not generate
friction with a side wall of the second groove segment 125 during rotation, thus avoiding
wear of the second segment 165 or the second groove segment 125.
