[0023] In the description of the present disclosure, the meaning of multiple refers to be
more than two, and the above is understood to include this number. In the description
of the present disclosure, if first, second and third are described, the descriptions
are utilized for the purpose of distinguishing the technical features only, and cannot

the specific meanings of the above words in the present disclosure in combination
with the specific contents of the technical solutions.
[0025] In the related art, an air conditioner is provided with a driving device for driving
parts. For example, an air outlet of the air conditioner is usually provided with
an air deflector, and the air deflector is driven by a motor to swing, thereby changing
a direction of an airflow. The motor driving the air deflector is usually located
inside a closed space, so the airflow is difficult to enter. Heat generated by the
motor needs to be transferred by other parts, and the heat dissipation efficiency
is low, which affects a service life of the motor. To solve the above problems, the
cold air at the air outlet of the air conditioner can be led into the mounting cavity
to realize heat dissipation of the motor. However, the cold air flowing out of the
mounting cavity may contact a housing of the air conditioner, resulting in the temperature
drop of the housing to cause condensation.
[0026] Based on this, the present disclosure provides a housing assembly for an air conditioner,
which is provided with an air guide member separated from a housing. The air guide
member can guide an airflow, and when a temperature of the airflow is low, a condensation
phenomenon caused by low-temperature air contacting the housing of the air conditioner
can be avoided. Different embodiments of the present disclosure will be described
below with reference to the drawings.
[0027] In some embodiments of the present disclosure, the housing assembly includes a housing
100, an air deflector, a frame 200 and an air guide member 300. The housing 100 is
located outside the housing assembly. The frame 200 is connected to the housing 100
and provided with a mounting cavity 210 and an air outlet 500 communicated with the
mounting cavity 210. The air deflector is rotatably arranged at the air outlet 500,
and the mounting cavity 210 is utilized for mounting a motor which drives the air
deflector to swing. The air guide member 300 is connected to the frame 200 and formed
with an air duct communicated with the mounting cavity 210. The air guide member 300
is arranged separately from the housing 100.
[0028] Referring to FIG. 1 to FIG. 3, the frame 200 in this embodiment is provided with
the mounting cavity 210 and the air outlet 500. In an implementation, the frame 200
is a single part or a collection of multiple parts. And in an implementation, the
mounting cavity 210 is formed inside the single part or among the multiple parts.
A position of the mounting cavity 210 is determined by a position of the motor 700.
Since the air deflector is mounted at the air outlet 500 of the housing assembly,
the motor 700 driving the air deflector to swing and the corresponding mounting cavity
210 are also close to the air outlet 500 of the housing assembly, that is, located
at a lower part of FIG. 1. The air deflector and the motor 700 and a corresponding
fixing structure can all be selected according to the existing technology.
[0029] Referring to FIG. 3, a third vent 220 is arranged on or among the parts utilized
to form the mounting cavity 210, and the third vent 220 is utilized to allow air at
the air outlet 500 to enter the mounting cavity 210, thus realizing air flow in the
mounting cavity 210 and accelerating heat dissipation of the motor 700.
[0030] Referring to FIG. 3 and FIG. 4, the air guide member 300 is located inside the housing
assembly and is provided with an air duct communicated with the mounting cavity 210.
The air guide member 300 is utilized for guiding the airflow flowing through the mounting
cavity 210, so that the airflow can follow a required path and is avoided from contacting
the housing 100.
[0031] The air guide member 300 is separated from the housing 100. The "housing 100" in
this embodiment refers to the part located outside the housing assembly, including
but not limited to an end cover, a panel, and the like. In an implementation, the
housing 100 is a single part or a collection of multiple parts. The housing 100 is
in contact with ambient normal temperature air during daily work, and if the temperature
of the housing 100 is lower than that of the ambient air, condensation is easily formed.
In this embodiment, the air guide member 300 is separated from the housing 100. Even
if low-temperature air flows in the air guide member 300, the temperature of the housing
100 can not be lowered due to contact with the cold air, so that condensation can
be avoided.
[0032] It can be understood that the housing assembly in this embodiment can be applied
to both an indoor unit of a split air conditioner and an integrated air conditioner.
[0033] In this embodiment, the housing assembly is provided with the mounting cavity 210
for mounting the motor 700 and the mounting cavity 210 is communicated with the air
outlet 500 of the housing assembly, so that the cold air at the air outlet 500 can
enter the mounting cavity 210 to realize rapid heat dissipation. In another embodiment,
the housing assembly is provided with the air guide member 300 to guide the airflow
flowing through the mounting cavity 210. Combined with the separate arrangement of
the air guide member 300 and the housing 100, a condensation phenomenon caused by
the cooling of the housing 100 can be avoided.
[0034] Referring to FIG. 4 to FIG. 7, in some embodiments of the present disclosure, the
housing assembly is provided with an accommodating cavity 400 for accommodating an
evaporator. One end of the air duct in the air guide member 300 is communicated with
the mounting cavity 210, and the other end of the air duct is communicated with the
accommodating cavity 400.
[0035] In an embodiment, the frame 200 is provided with a third vent 220. In this embodiment,
the third vent 220 serves as an air inlet of the mounting cavity 210, and the mounting
cavity 210 is communicated with the air outlet 500 of the housing assembly through
the third vent 220. The air guide member 300 is utilized to guide the airflow flowing
out of the mounting cavity 210. One end of the air guide member 300 is communicated
with the air outlet of the mounting cavity 210, and the other end of the air guide
member 300 is communicated with the accommodating cavity 400 of the housing assembly
for accommodating the evaporator of the air conditioner. When the housing assembly
of this embodiment is applied to the air conditioner, the low-temperature air at the
air outlet of the air conditioner enters the mounting cavity 210 through the third
vent 220, cools the motor 700, and then enters the accommodating cavity 400 through
the air guide member 300. That is, the low-temperature air at the air outlet can be
utilized to dissipate heat in this embodiment, which is helpful to improve a heat
dissipation effect, and the low-temperature air flowing out of the mounting cavity
210 can flow back to the accommodating cavity 400, thus preventing the low-temperature
air from contacting the housing 100.
[0036] Referring to FIG. 3, FIG. 6 and FIG. 7, in some embodiments of the present disclosure,
the frame 200 includes a surface frame 230 and an air outlet frame 240. The surface
frame 230 and the air outlet frame 240 define the mounting cavity 210. A third vent
220 is formed between the surface frame 230 and the air outlet frame 240, and the
mounting cavity 210 is communicated with the air outlet 500 through the third vent
220.
[0037] In this embodiment, the frame 200 includes the surface frame 230 and the air outlet
frame 240, which define the mounting cavity 210. The third vent 220 is formed between
the surface frame 230 and the air outlet frame 240. In an implementation, one side
of the air outlet frame 240 (for example, the lower left side in FIG. 7) is provided
with a mounting box 241, and one side of the mounting box 241 (for example, the left
side in FIG. 7) is provided with an opening. When connecting, the mounting cavity
210 can be defined by making the opening side of the mounting box 241 face the surface
frame 230 and making the mounting box 241 close to but not contacting the surface
frame 230, and a gap between the mounting box 241 and the surface frame 230 is the
third vent 220. In this embodiment, the slender gap between the surface frame 230
and the air outlet frame 240 is utilized as the third vent 220, which can prevent
a user from touching an internal motor on the premise of meeting ventilation requirements.
At the same time, it is not necessary to separately process the third vent 220 on
the surface frame 230 and the air outlet frame 240, which helps to reduce the processing
cost.
[0038] In some embodiments of the present disclosure, the housing assembly includes a surface
frame 230 and an air outlet frame 240. The surface frame 230 and the air outlet frame
240 define a mounting cavity 210. The air outlet frame 240 is provided with a third
vent 220, and the mounting cavity 210 is communicated with the air outlet 500 through
the third vent 220.
[0039] In this embodiment, the frame 200 includes the surface frame 230 and the air outlet
frame 240, which define the mounting cavity 210, and the third vent 220 is formed
on the air outlet frame 240 alone. For example, in an implementation, one side of
the air outlet frame 240 (for example, the lower left side in FIG. 7) is provided
with a mounting box 241, and one side of the mounting box 241 (for example, the left
side in FIG. 7) is provided with an opening. When connecting, the mounting cavity
210 can be defined by fitting the opening side of the mounting box 241 with the surface
frame 230, and the third vent 220 can be formed on a box wall of the mounting box
241, so that the surface frame 230 and the air outlet frame 240 can form an integrated
structure, or the surface frame 230 and the air outlet frame 240 can be connected
by a fastener after fitting, and meanwhile, the third vent 220 is arranged on the
air outlet frame 240 closer to the air outlet of the air conditioner, which facilitates
air intake.
[0040] Referring to FIG. 3, in some embodiments of the present disclosure, the housing assembly
includes a surface frame 230 and an end cover 110. The end cover 110 is connected
to the surface frame 230, and an air guide member 300 is located between the end cover
110 and the surface frame 230, and is separately arranged from the end cover 110.
[0041] In this embodiment, the frame 200 includes a surface frame 230, and the housing 100
includes the end cover 110. The end cover 110 is connected to the outside of the surface
frame 230. And usually, the end cover 110 and the surface frame 230 define an empty
cavity 600. The air guide member 300 is mounted inside the empty cavity 600, which
can make full use of the existing space of the housing assembly. The air guide member
300 is not in contact with the end cover 110, which can avoid the end cover 110 from
condensation.
[0042] In some embodiments of the present disclosure, the air guide member 300 is detachably
connected to the frame 200, so that the air guide member 300 can be replaced after
ageing. In an implementation, the air guide member 300 can be connected to the frame
200 by a fastener or a buckle structure, and can also be connected to the frame 200
by an adhesive tape.
[0043] Referring to FIG. 8 and FIG. 9, in some embodiments of the present disclosure, the
frame 200 is provided with a first vent 231, a first flange 232, a second vent 233
and a second flange 234. The first flange 232 surrounds the first vent 231, and the
second flange 234 surrounds the second vent 233. The air guide member 300 includes
a first connecting portion 320, a body portion 310 and a second connecting portion
330 which are connected in sequence. The first connecting portion 320 is sleeved on
the first flange 232, so that the air duct of the air guide member 300 is communicated
with the mounting cavity 210 through the first vent 231, and the second connecting
portion 330 is sleeved on the second flange 234, so that the air duct of the air guide
member 300 is communicated with the accommodating cavity 400 through the second vent
233, thus realizing quick disassembly between the air guide member 300 and the frame
200.
[0044] Similarly, taking the surface frame 230 as the frame 200 as an example, the surface
frame 230 is formed with the first vent 231 and the first flange 232. The first vent
231 leads to the mounting cavity 210, and the first flange 232 surrounds an outside
of the first vent 231 along a circular track or a square track. A shape of the first
connecting portion 320 is adapted to a shape of the first flange 232, such as a square
structure in FIG. 9. In an implementation, the first connecting portion 320 can be
an elastic structure made of rubber, silica gel and other materials. When in use,
the first connecting portion 320 is stretched and sleeved outside the first flange
232, and the first connecting portion 320 can be tightly connected to the first flange
232 after contracting. When dismounting, the first connecting portion 320 can be separated
only by pulling, which is simple to operate.
[0045] In another embodiment, the other end of the air guide member 300 can also be connected
to the surface frame 230 in a similar way. In an implementation, the surface frame
230 is formed with a second vent 233 and a second flange 234. The second vent 233
leads to the accommodating cavity 400 where the evaporator is placed, and the second
flange 234 surrounds an outside of the second vent 233 along a circular track or a
square track. The air guide member 300 includes a second connecting portion 330. The
second connecting portion 330, the main body portion 310 and the first connecting
portion 320 are connected in sequence, and a shape of the second connecting portion
330 is adapted to a shape of the second flange 234, such as a square structure in
FIG. 9. In an implementation, the second connecting portion 330 can also be an elastic
structure made of rubber, silica gel and other materials, and the second connecting
portion 330 can be connected by being sleeved outside the second flange 234.
[0046] It can be understood that the shapes of the first connecting portion 320 and the
second connecting portion 330 are not limited to the shapes described in above embodiments.
In some embodiments, the shapes of the first connecting portion 320, the second connecting
portion 330 and the body portion 310 can also be the same. For example, the air guide
member 300 is an air guide pipe with a constant cross section, and both ends of the
air guide pipe are utilized as the first connecting portion 320 and the second connecting
portion 330 respectively.
[0047] Referring to FIG. 8, the frame is provided with a plurality of the first vents 231
and a plurality of the second vents 233. The first flange 232 surrounds outside of
the plurality of the first vents 231 and the second flange 234 surrounds outside the
plurality of the second vents 233.
[0048] Taking the surface frame 230 as the frame 200 as an example, the surface frame 230
is provided with a plurality of the first vents 231 and a plurality of the second
vents 233. Correspondingly, the first flange 232 surrounds the plurality of the first
vents 231 and the second flange 234 surrounds the plurality of the second vents 233,
so that the strength of the surface frame 230 can be increased through the arrangement
of this embodiment under the same vent hole area compared with that of a single vent
hole. It can be understood that numbers of the first vent 231 and the second vent
233 are not limited in this embodiment, and can be two, three, four or other numbers.
[0049] In some embodiments of the present disclosure, the body portion 310 of the air guide
member 300 can be a hose tube made of rubber, silica gel, and the like, so that the
air guide member 300 can be bent and mounted conveniently. In an embodiment, other
parts of the air guide member 300, such as the first connecting portion 320 and the
second connecting portion 330, can be made of the same material as the body portion
310, that is, the air guide member 300 has an integrated structure. In another embodiment,
the materials of the first connecting portion 320 and the second connecting portion
330 can also be different from the material of the body portion 310, for example,
the body portion 310 has a flexible structure, and the first connecting portion 320
and the second connecting portion 330 have a rigid structure.
[0050] In some embodiments of the present disclosure, an indoor unit of an air conditioner
is proposed. The indoor unit of the air conditioner includes the housing assembly
of the above embodiments, and the motor 700 for driving the air deflector to rotate
on the indoor unit of the air conditioner is located in the mounting cavity 210. When
a fan of the indoor unit of the air conditioner drives cold air to be discharged from
the air outlet 500, the fan can also drive the cold air to enter the mounting cavity
210, thus realizing rapid heat dissipation of the motor 700.
[0051] This embodiment is applied to various air conditioners with indoor units, such as
wall-mounted air conditioners, cabinet air conditioners, ceiling air conditioners,
and the like.
[0052] In the embodiment, as shown in FIG. 3, the body portion of the motor 700 is fixed
inside the mounting cavity 210, and a driving shaft of the motor 700 is directly or
indirectly connected to the air deflector (not shown in the figure) outside the mounting
cavity 210 through a shaft sleeve and other structures, which can not only avoid touching
the motor by the user, but also can drive the air deflector.
[0053] The fan is located inside the housing 100 for forcing airflow into the mounting cavity
210. This embodiment can adopt the existing fan of the indoor unit of the air conditioner
to form an airflow for heat dissipation, which is favorable for reducing the cost.
The fan and a corresponding fixing structure can both be selected according to the
existing technology.
