following detailed description is, therefore, not to be taken in a limiting sense,
and the scope of the present invention is defined only by the appended claims.
[0010] FIG. 1 is a perspective view of an indoor unit of an air conditioner according to
the present embodiment, FIG. 2 is an exploded perspective view of the air conditioner
according to the present embodiment, and FIG. 3 is a vertical cross-sectional view
of the air conditioner according to the present embodiment.
[0011] In FIG. 1, a wall type indoor unit is shown by way of example.
[0012] Referring to FIGS. 1 to 3, the indoor unit 1 according to the present embodiment
includes a main body 10 in which various components are provided, and a front panel
30 that is coupled rotatably to the main body 10 to selectively open the main body
10.
[0013] The main body 10 includes a chassis 11, a front frame 14 that is coupled to the front
surface of the chassis 11 and is formed with a suction grill 141, a pre-filter 15
that purifies air sucked through the suction grill 141, a heat-exchanger 16 that performs
heat exchange between the air passing through the pre-filter 15 and internal refrigerant,
a fan 17 that compulsorily flows the air, a fan motor 18 that rotates the fan 17,
a control box 20 that is configured of components for controlling the operation of
the indoor unit 1, a discharge assembly 23 that guides the discharge of the air passing
through the heat-exchanger 16, a louver unit 24 that controls the direction of the
discharged air, and a dust collector 25 that is coupled to the heat-exchanger 16.
[0014] And, the front panel 30 is disposed in front of the front frame 14 and an install
panel 40 that allows the indoor unit 1 to be installed on a wall is coupled to the
rear side of the chassis 11.
[0015] More specifically, the suction grill 141 is formed on the top surface of the front
frame 14 by way of example. The suction grill 141 forms inlet holes through which
air is sucked and serves to protect the heat-exchanger 16 from the outside.
[0016] One or more opening parts 142 that allow the pre-filter 15 to come and go are formed
on the front surface of the front frame 14. In FIG. 2, two opening parts 142 are shown
by way of example but there is no limitation in the number of the opening part 142.
And, the opening part 142 and the pre-filter 15 are provided in the same number.
[0017] The opening part 142 is opened and closed by the front panel 30 that is coupled rotatably
to the front frame 14. The lower end of the front panel 30 may be rotated centering
on the upper end thereof by way of example.
[0018] Therefore, after rotating the front panel 30, the pre-filter 15 can be mounted or
the pre-filter 15 can be drawn out through the opening part 142. Also, a filter supporting
part 144 that supports the pre-filter 15 is formed at the front frame 14. Herein,
although not shown, a plasma filter can be coupled to the front of the filter supporting
part 144.
[0019] A service hole 143 for the replacement or repair, etc. of the control box 20 is formed
at the front surface of the front frame 14. The service hole 143 may be opened and
closed by a service cover 145 coupled to the front frame 14.
[0020] And, in a state where the service cover 145 covers the service hole 143, the service
cover 145 is covered by the front panel 30. Therefore, in order to replace or repair
the control box 20, the service cover 145 is separated after the front panel 30 is
rotated.
[0021] One or more air flowing holes 149 that flow air are formed at one side surface (for
example, right side surface in FIG. 2) of the front frame 14.
[0022] The heat-exchanger 16 is bent one times or more so that it may be divided into a
plurality of portions. In the present embodiment, the heat-exchanger 16 is shown to
be divided into three portions by way of example. And, the pre-filter 15 is positioned
at the upper stream side of the heat-exchanger 16.
[0023] A heat-exchanger holder 161 is coupled to one side of the heat-exchanger 16 and a
plurality of fixing plates 163 and 164 are coupled to the other side of the heat-exchanger
16. And, as the heat-exchanger holder 161 and the plurality of fixing plates 163 and
164 are fixed to the chassis 11, the position of the heat-exchanger 16 is fixed. The
heat-exchanger 16 is connected to an outdoor unit that is not shown by a pipe unit
165.
[0024] As the fan 17, a cross flow fan may be applied. And, the fan motor 18 is coupled
to the fan 17 in one side direction of the fan 17. And, the control box 20 is disposed
in the side direction of the fan motor 18.
[0025] In other words, in the present embodiment, the fan motor is positioned between the
fan 17 and the control box 20.
[0026] The control box 20 includes a box body 21 in which various components such as a PCB,etc.
are installed, and a box cover 22 that covers the box body 21.
[0027] In order to guide the flow of the fan 17, a flow guide 111 is formed at the chassis
11, and a stabilizer 232 is formed in the discharge assembly 23. And, an outlet 231
through which the heat-exchanged air is discharged to the indoor is formed in the
discharge assembly 23.
[0028] In other words, the discharge channel of the heat-exchanged air is defined by the
flow guide 111 and the discharge assembly 23.
[0029] Meanwhile, a temperature sensor 219 that senses the temperature of indoor air sucked
through the air flow hole 149 is provided at one side of the box body 21, that is,
at a surface facing a surface on which the air flow hole 149 of the front frame 14
is formed.
[0030] The temperature sensed by the temperature sensor 219 is transmitted to a controller
not shown (it may be an element that constitutes the control box), and the controller
compares a set temperature (desire temperature) with the temperature sensed by the
temperature sensor 219 to control the operation of the indoor unit or the outdoor
unit.
[0031] According to the present embodiment, the air flow hole 149 is formed at the side
surface of the front frame 14 so that the temperature of the air sucked through the
air flow hole 149 is sensed by the temperature sensor 219, making it possible to exactly
sense the current indoor temperature.
[0032] In other words, the air flow hole 149 is positioned to be spaced from the outlet
231 so that it is difficult for the discharge air to be flowed into through the air
flow hole 149. Therefore, the indoor air is flowed into through the air flow hole
149, making it possible to exactly sense the current indoor temperature.
[0033] FIGS. 4 and 5 are partially exploded perspective views showing the internal constitution
of the air conditioner according to the present embodiment, FIG. 6 is a perspective
view of the chassis according to the present embodiment, and FIG. 7 is a diagram showing
the position relation between the pipe unit and the chassis according to the present
embodiment.
[0034] Referring to FIGS. 1 to 7, a fan receiving part in which both sides of the fan 17
are received is included in the chassis 11 according to the present embodiment. The
fan receiving part includes a first fan receiving part 112 and a second fan receiving
part 113. And, the channel guide 111 is positioned between the first receiving part
112 and the second receiving part 113.
[0035] A first receiving groove 112a that receives a portion of the left side of the fan
17 and has a vertical cross-section in an approximately semicircular shape is formed
in the first receiving part 112. Also, although not shown in the first receiving part
112, a bearing seating part 112b on which a bearing that is coupled to the left side
of the fan 17 to guide the rotation of the fan 17 is seated is formed.
[0036] A second receiving groove 113a that receives the right entirety of the fan 17 is
formed in the left side of the second receiving part 113. And, a fan motor seating
part 120 on which the fan motor 18 is seated is formed on the right side of the second
receiving part 113, and a control box seating part 130 on which the control box 20
is seated is formed at one side of the fan motor seating part 120.
[0037] And, a shaft penetration hole 115 through which a motor shaft 181 of the fan motor
18 penetrates is formed in the second receiving part 113. The motor shaft 181 penetrates
through the shaft penetration hole 115 in right and left directions.
[0038] The shaft penetration hole 115 includes a first hole 115a formed in the central portion
of the second receiving part 113 and a second hole 115b that is extended forward from
the first hole 115a. The first hole 115a has a vertical cross-section formed in a
circular shape.
[0039] Therefore, the shaft penetration hole 115 is formed entirely in a non circular shape,
wherein the front and rear length is formed to be longer than the top and bottom width.
This is to allow the motor shaft 181 to be easily coupled to the fan 17. The detailed
reasons thereof will be described later.
[0040] The fan motor seating part 120 includes a first supporting part 122 and a second
supporting part that support both sides of the fan motor 18, and a motor receiving
space 121 that is formed between the first supporting part 122 and the second supporting
part 123 to receive the fan motor 18 therein.
[0041] The first supporting part 122 is integrally formed at the right side surface of the
second receiving part 113, and the second supporting part 123 is integrally formed
at the front surface of the control box seating part 130. The second supporting part
123 is projected forward from the front surface of the control box seating part 130.
[0042] That is, the first supporting part 122 is not spaced from the second receiving part
113 but is integrally formed at the right side surface of the second receiving part
113. In other words, no gap is formed between the first supporting part 122 and the
second receiving part 113.
[0043] Therefore, according to the present embodiment, since the fan motor 18 is positioned
directly at the right side of the second receiving part 113, the length of the motor
shaft 181 of the fan motor 18 can be minimized so that the horizontal size of the
indoor unit 1 becomes small, making it possible to make the indoor unit compact.
[0044] And, if the fan motor 18 is seated on the fan motor seating part 120, an end portion
181a adjacent to a first reduction part 182 of the motor shaft 181 is seated on the
shaft penetration hole 115, specifically, on the first hole 115a. From a different
point of view, the most inner portion from the motor shaft 181 projected from the
fan motor 18 may be explained to be positioned on the first hole 115a.
[0045] In the present embodiment, as the fan motor 18, an AC motor or a BLDC motor may be
used by way of example.
[0046] And, the cross-section of a portion at least coupled to the fan 17, of the motor
shaft 181 of the fan motor 18, is formed in a non-circular shape. For example, the
cross-section of the motor shaft 181 may be formed in a
?shape.
[0047] Seating grooves 122a and 123a each in a semicircular shape are formed in the first
supporting part 122 and the second supporting part 123. And, one or more cooling holes
124 through which air for cooling the fan motor 18 is flowed are formed in the fan
motor seating part 120.
[0048] A vibration reduction part formed of elastic material that minimizes vibration in
a state the fan motor 18 is seated on the fan motor seating part 120 is coupled to
both sides of the fan motor 18. In the present embodiment, it will be explained that
the vibration reduction part constitutes a portion of the fan motor 18.
[0049] The vibration reduction part includes a first reduction part 182 that is coupled
to the left side of the fan motor 18, and a second reduction part 184 (shown in FIG.
2) that is coupled to the right side of the fan motor 18.
[0050] Substantially, the first reduction part 182 is seated on the first supporting part
122 and the second reduction part 184 is seated on the second supporting part 123.
[0051] And, one or more supporting ribs 126 that support the fan motor cover 19 are formed
on the inner circumferential surface of the fan motor seating part 120.
[0052] Meanwhile, the control box seating part 130 is projected forward from the back surface
part 110 of the chassis 11.
[0053] In other words, the control box seating part 130 includes a plurality of extending
parts 130a that are substantially vertically extended forward based on the back surface
part 110 and a connecting part 130b that connects the front ends of the plurality
of extending parts 130a.
[0054] Therefore, the horizontal cross-section of the control box seating part 130 is formed
in a
shape, having a rear surface that is opened, and a space part 131 is defined by the
plurality of extending part 130a and the connecting part 130b. The space part 131
is formed to be vertically long.
[0055] From a different point of view, the space part 131 may be understood to be formed
as the back surface part of the chassis 110 is collapsed forward.
[0056] And, the pipe unit 165 positioned in the space part 13 and the space part 131 are
covered by the install panel 40.
[0057] And, a side surface opening part 132 through which the pipe unit 165 passes is formed
at the extending part 130a adjacent to the fan motor seating part 120, of the plurality
of extending parts 130a.
[0058] One or more reinforcing ribs 133 that improve the strength of the control box seating
part 130 are formed at the control box seating part 130. In FIG. 7, a plurality of
reinforcing ribs 133 are formed at the back surface of the control box seating part
130 by way of example, wherein the plurality of reinforcing ribs 133 are spaced vertically
from each other.
[0059] The reinforcing ribs 133 are formed over the plurality of extending parts 130a and
the connecting part 130b.
[0060] Although the pipe unit 165 positioned in the space part 131 is bumped into the control
box seating part 130 at the time of installation of the pipe unit 165, the breakage
of the control box seating part 130 can be prevented by the reinforcing ribs 133.
[0061] And, a guide rib 135 that guides the seating of the control box 20 is formed at the
front surface part of the control box seating part 130.
[0062] Referring to FIG. 7, the pipe unit 165 connected to the heat-exchanger 16 is extended
backward to the back surface part 110 of the chassis 11 and is bent on the upper of
the fan motor seating part 120, thereby being extended in right and left directions
through the side surface opening part 132.
[0063] And, the pipe unit 165 passing through the side surface opening part 132 is bent
downward from the space part 131. And, the pipe unit 165 is extended downward along
the space part 131, thereby being drawn out to the outside of the main body 10.
[0064] According to the present embodiment as described above, the pipe unit 165 connected
to the heat-exchanger 16 is vertically extended from the rear of the control box seating
part 130 so that the main body 10 does not require a space for avoiding the pipe unit
165, having advantages that product size becomes small and the fan motor 18 and the
control box 20 are easily installed.
[0065] In other words, since the pipe unit 165 is positioned in the rear of the control
box 20 by passing through the upper of the fan motor 18, interference with the fan
motor 18 disappears so that the fan motor 18 and the fan 17 can be positioned to be
adjacent to each other at maximum, making it possible to reduce the entire size of
the product.
[0066] Compared with the related art, when the pipe unit 165 is positioned in front of the
fan motor 18 or in front of the control box 20, the fan motor 18 and the control box
20 should be installed by avoiding the pipe unit 165 so that the entire size of the
main body 10 becomes large and it is difficult to install the fan motor 18 and the
control box 20. However, with the present embodiment, these problems can be solved.
[0067] FIG. 8 is a perspective view of the fan motor cover according to the present embodiment,
FIG. 9 is a perspective view of the fan according to the present embodiment, and FIG.
10 is a diagram showing a state where the fan motor cover is coupled to the chassis.
[0068] Referring to FIGS. 1 to 10, the fan motor cover 19 has a vertical cross-section formed
in an approximately C shape. The fan motor cover 19 covers a portion of the fan motor
18 that is projected to the external side of the motor receiving space 121 in a state
where the fan motor 18 is received in the motor receiving space 121. In other words,
the portion of the fan motor 18 is received in the motor receiving space 121 and the
rest of the fan motor 18 are covered by the fan motor cover 19.
[0069] A first covering part 192 that covers the first reduction part 182 seated on the
first supporting part 122 and an attaching/detaching hook 193 that is hung by a hanging
end 114 formed at the side surface of the right-side receiving part 113 are formed
at the left side of the fan motor cover 19.
[0070] A first engagement end 194 that is engaged with the second supporting part 123 by
an engagement member (not shown) is formed at the right side of the fan motor cover
19. A first engagement hole 194a through which the engagement member penetrates is
formed in the first engagement end 194.
[0071] And, an engagement hook 196 that is engaged with the box body 21 is formed at the
top surface (or front surface) of the fan motor cover 19.
[0072] Therefore, in a state where the fan motor 18 is received in the motor receiving space
121, the attaching/detaching hook 193 is primarily hanged by the hanging end 114 so
that the position of the fan motor cover 19 can be fixed. And, the first engagement
end 194 of the fan motor cover 19 is put on the top surface of an engagement part
125 formed at the second supporting part 123 and the fan motor cover 19, specifically,
the first covering part 192, covers the top side of the first reduction part 182.
[0073] If the first covering part 192 covers the first reduction part 182 in a state where
the first reduction part 182 is seated on the first supporting part 122, the moving
of the first reduction part 182 can be prevented.
[0074] In other words, in the present embodiment, the fan motor cover 19 allows one side
of the fan motor 18, that is, the position of the first reduction part 182, to be
fixed.
[0075] Meanwhile, the fan 17 includes a plurality of blades 172 that are spaced from each
other and a connecting part 174 that connects the blades 172. The basic structure
of the fan is the same as the structure of the publicly known cross flow fan so that
the detailed description thereof will be omitted.
[0076] A shaft coupling part 175 that couples a motor shaft 181 of the fan motor 18 is formed
at the connection part positioned on the outermost outside, of the connecting part
174. And, a shaft coupling hole 176 is formed in the shaft coupling part 175. The
shaft coupling hole 176 is formed in the shape corresponding to the motor shaft 181.
In other words, the shaft coupling hole 176 and the motor shaft 181 are formed in
a non-circular shape, making it possible to prevent the motor shaft 181 from idling
as to the fan 17.
[0077] FIG. 11 is a perspective view of the box body according to the present embodiment,
and FIG. 12 is a perspective view showing a state where the box body according to
the present embodiment is seated on the control box seating part.
[0078] Referring to FIGS. 1 to 12, the box body 21 includes a frame 210 whose vertical cross-section
is formed in an approximately "
" shape and front surface is opened. And, various components such as a PCB, etc.
may be installed through the opened front surface of the frame 210. At least a portion
of the opened front surface of the frame 210 may be covered by the box cover 22.
[0079] A second covering part 212 that covers the second reduction part 184, a second engagement
end 215 that is engaged with the first engagement end 194 by the engagement member,
and a hook hanger 214 by which the engagement hook 196 is hanged and formed at one
side surface of the frame 210 (left-side surface in FIG. 11). And, a second engagement
hole 215a with which the engagement member is engaged is formed in the second engagement
end 215.
[0080] In the present embodiment, the engagement hook 196 is described to be formed at the
fan motor cover 19 and the hook hanger 214 is described to be formed at the frame
210, that is, at the control box. However, differently therefrom, the engagement hook
may also be formed at the frame and the hook hanger may also be formed at the fan
motor cover.
[0081] A switch seating part 216 on which a switch 218 (see FIG. 4) that senses the closing
of the front panel 30 is seated is formed at the front surface side of the frame 210.
[0082] And, if the box body 21 is seated on the control box seating part 130, the second
supporting part 123 and the second covering part 212 are aligned. And, the second
reduction part 184 is positioned between the second supporting part 123 and the second
covering part 212.
[0083] In other words, in the present embodiment, the box body 21 allows the other side
of the fan motor 18, that is, the position of the second reduction part 184, to be
fixed.
[0084] Hereinafter, the assembling order of the main body in connection with the fan motor
and the control box will be described.
[0085] FIG. 13 is a perspective view showing a state where the fan motor is coupled to the
fan.
[0086] Referring to FIGS. 1 to 13, the right side of the fan 17 is received in the second
receiving part 113 and the left side of the fan 17 is received in the first receiving
part 112. Then, the motor shaft 181 of the fan motor 18 penetrates through the shaft
penetration hole 115 to allow the motor shaft 181 to be coupled to the right side
of the fan 17.
[0087] More specifically, the motor shaft 181 first penetrates through the second hole 115b
and then the motor shaft 181 moves to the first hole 115a. And, the fan motor 18 is
seated on the fan motor seating part 120, while the motor shaft 181 moved to the first
hole 115a being coupled to the shaft coupling part 175.
[0088] Since the first supporting part 122 is formed at the right side of the second receiving
part 113, the motor shaft 181 becomes short compared to that in the related art so
that the motor shaft 181 straightly passes through the first hole 115a, being difficult
to be coupled to the shaft coupling part 175. However, in the present embodiment,
a second hole 115b extended from the first hole 115a is additionally formed. Therefore,
while the motor shaft 181 being moved to the first hole 115a after the motor shaft
181 first passes through the second hole 115b, if the coupling and of the motor shaft
181 and the seating of the fan motor 18 are performed, the motor shaft 181 can be
coupled to the shaft coupling part 175.
[0089] If the motor shaft 181 is coupled to the fan 17, the first reduction part 182 is
seated on the first supporting part 122, the second reduction part 184 is seated on
the second supporting part 123, and a portion of the fan motor 18 is received nit
eh motor receiving space 121. Thereafter, the fan motor cover 19 covers the fan motor
18. Then, the attaching/detaching hook 193 is hanged by the hanging end 114 and the
first covering part 192 covers the first reduction part 182.
[0090] Thereafter, the control box 20 is seated on the control box seating part 130. Then,
the second covering part 212 covers the second reduction part 184, the engagement
hook 196 is hanged by the hook hanger 214, and the second engagement end 215 is put
on the top surface of the first engagement end 194.
[0091] And, the engagement member allows the second engagement end 214, the first engagement
end 195, and the engagement part 125 to be simultaneously engaged.
[0092] Therefore, according to the present embodiment, since the fan motor is positioned
directly at the right side of the second receiving part, the length of the motor shaft
of the fan motor can be minimized so that the horizontal size of the indoor unit becomes
small, making it possible to make the indoor unit compact.
[0093] Moreover, since the fan motor cover covers one side of the fan motor and the control
box controls the other side of the fan motor, the fan motor and the control box are
positioned to be adjacent to each other, making it possible to reduce the horizontal
width of the main body.
[0094] Furthermore, since the pipe unit passes through the rear of the control box, an additional
space for avoiding the pipe unit is not required, making it possible to increase space
utilization.
[0095] FIG. 14 is a cross-sectional view showing the relation between the switch and the
front panel in a state where the front panel is closed.
[0096] Referring to FIGS. 2, 5, and 14, the switch 218 is seated at a front portion of the
box body 21 (portion facing the front panel) and the switch 218 faces the front in
a state where the box body 21 is seated on the control box seating part 130.
[0097] Meanwhile, a pressing part 302 that selectively presses the switch 218 is projected
backward from the back surface of the front panel 30, and a penetration hole 148 through
which the pressing part 302 is selectively penetrated is formed in the front frame
14. The penetration hole 148 is positioned downward the service hole 143.
[0098] Referring to FIG. 10, the pressing part 302 presses the switch 218 by penetrating
through the penetration hole 148 in a state where the front panel 30 is closed. The
switch 218 is for sensing the state where the front panel 30 is closed. If the switch
218 is pressed, the switch 218 is turned on and the turn-on signal of the switch 218
is transmitted to the controller not shown. Then, the controller operates the dust
collector and/or the plasma filter.
[0099] In other words, if the turn-on signal of the indoor unit is input in a state where
the front panel 30 is not closed, the controller does not operate the dust collector
and/or the plasma filter and when the closing of the front panel 30 is sensed, the
controller operates the dust collector and/or the plasma filter.
[0100] With the present embodiment, as the control box seating part is projected forward
from the chassis, the switch can be positioned to be adjacent to the penetration hole
in a state where the box body is seated on the control box seating part.
[0101] Therefore, the pressing part formed at the back surface of the front panel can press
directly the switch seated on the box body, making it possible to smoothly arrange
electrical wires connected to the switch.
