front panel 30 is disposed in front of thefront frame 14 and aninstall panel 40 that allows the indoor unit 1 to be installed on a wall is coupled to the rear side of thechassis 11. - More specifically, the
suction grill 141 is formed on the top surface of thefront frame 14 by way of example. Thesuction grill 141 forms inlet holes through which air is sucked and serves to protect the heat-exchanger 16 from the outside. - One or more
opening parts 142 that allow the pre-filter 15 to come and go are formed on the front surface of thefront frame 14. InFIG. 2 , twoopening parts 142 are shown by way of example but there is no limitation in the number of theopening part 142. And, theopening part 142 and the pre-filter 15 are provided in the same number. - The
opening part 142 is opened and closed by thefront panel 30 that is coupled rotatably to thefront frame 14. The lower end of thefront panel 30 may be rotated centering on the upper end thereof by way of example. - Therefore, after rotating the
front panel 30, the pre-filter 15 can be mounted or the pre-filter 15 can be drawn out through theopening part 142. Also, a filter supporting part 144 that supports the pre-filter 15 is formed at thefront frame 14. Herein, although not shown, a plasma filter can be coupled to the front of the filter supporting part 144. - A
service hole 143 for the replacement or repair, etc. of thecontrol box 20 is formed at the front surface of thefront frame 14. Theservice hole 143 may be opened and closed by aservice cover 145 coupled to thefront frame 14. - And, in a state where the
service cover 145 covers theservice hole 143, theservice cover 145 is covered by thefront panel 30. Therefore, in order to replace or repair thecontrol box 20, theservice cover 145 is separated after thefront panel 30 is rotated. - One or more
air flowing holes 149 that flow air are formed at one side surface (for example, right side surface inFIG. 2 ) of thefront frame 14. - 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. - A heat-
exchanger holder 161 is coupled to one side of the heat-exchanger 16 and a plurality offixing plates exchanger 16. And, as the heat-exchanger holder 161 and the plurality offixing plates 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 apipe unit 165. - As the
fan 17, a cross flow fan may be applied. And, thefan motor 18 is coupled to thefan 17 in one side direction of thefan 17. And, thecontrol box 20 is disposed in the side direction of thefan motor 18. - In other words, in the present embodiment, the fan motor is positioned between the
fan 17 and thecontrol box 20. - The
control box 20 includes abox body 21 in which various components such as a PCB,etc. are installed, and abox cover 22 that covers thebox body 21. - In order to guide the flow of the
fan 17, aflow guide 111 is formed at thechassis 11, and astabilizer 232 is formed in thedischarge assembly 23. And, anoutlet 231 through which the heat-exchanged air is discharged to the indoor is formed in thedischarge assembly 23. - In other words, the discharge channel of the heat-exchanged air is defined by the
flow guide 111 and thedischarge assembly 23. - Meanwhile, a
temperature sensor 219 that senses the temperature of indoor air sucked through theair flow hole 149 is provided at one side of thebox body 21, that is, at a surface facing a surface on which theair flow hole 149 of thefront frame 14 is formed. - 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 thetemperature sensor 219 to control the operation of the indoor unit or the outdoor unit. - According to the present embodiment, the
air flow hole 149 is formed at the side surface of thefront frame 14 so that the temperature of the air sucked through theair flow hole 149 is sensed by thetemperature sensor 219, making it possible to exactly sense the current indoor temperature. - In other words, the
air flow hole 149 is positioned to be spaced from theoutlet 231 so that it is difficult for the discharge air to be flowed into through theair flow hole 149. Therefore, the indoor air is flowed into through theair flow hole 149, making it possible to exactly sense the current indoor temperature. -
FIGS. 4 and5 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, andFIG. 7 is a diagram showing the position relation between the pipe unit and the chassis according to the present embodiment. - Referring to
FIGS. 1 to 7 , a fan receiving part in which both sides of thefan 17 are received is included in thechassis 11 according to the present embodiment. The fan receiving part includes a firstfan receiving part 112 and a secondfan receiving part 113. And, thechannel guide 111 is positioned between the first receivingpart 112 and the second receivingpart 113. - A
first receiving groove 112a that receives a portion of the left side of thefan 17 and has a vertical cross-section in an approximately semicircular shape is formed in the first receivingpart 112. Also, although not shown in the first receivingpart 112, abearing seating part 112b on which a bearing that is coupled to the left side of thefan 17 to guide the rotation of thefan 17 is seated is formed. - A
second receiving groove 113a that receives the right entirety of thefan 17 is formed in the left side of the second receivingpart 113. And, a fanmotor seating part 120 on which thefan motor 18 is seated is formed on the right side of the second receivingpart 113, and a controlbox seating part 130 on which thecontrol box 20 is seated is formed at one side of the fanmotor seating part 120. - And, a
shaft penetration hole 115 through which amotor shaft 181 of thefan motor 18 penetrates is formed in the second receivingpart 113. Themotor shaft 181 penetrates through theshaft penetration hole 115 in right and left directions. - The
shaft penetration hole 115 includes afirst hole 115a formed in the central portion of the second receivingpart 113 and asecond hole 115b that is extended forward from thefirst hole 115a. Thefirst hole 115a has a vertical cross-section formed in a circular shape. - 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 themotor shaft 181 to be easily coupled to thefan 17. The detailed reasons thereof will be described later. - The fan
motor seating part 120 includes a first supporting part 122 and a second supporting part that support both sides of thefan motor 18, and amotor receiving space 121 that is formed between the first supporting part 122 and the second supportingpart 123 to receive thefan motor 18 therein. - The first supporting part 122 is integrally formed at the right side surface of the second receiving
part 113, and the second supportingpart 123 is integrally formed at the front surface of the controlbox seating part 130. The second supportingpart 123 is projected forward from the front surface of the controlbox seating part 130. - 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 receivingpart 113. In other words, no gap is formed between the first supporting part 122 and the second receivingpart 113. - Therefore, according to the present embodiment, since the
fan motor 18 is positioned directly at the right side of the second receivingpart 113, the length of themotor shaft 181 of thefan 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. - And, if the
fan motor 18 is seated on the fanmotor seating part 120, anend portion 181a adjacent to afirst reduction part 182 of themotor shaft 181 is seated on theshaft penetration hole 115, specifically, on thefirst hole 115a. From a different point of view, the most inner portion from themotor shaft 181 projected from thefan motor 18 may be explained to be positioned on thefirst hole 115a. - In the present embodiment, as the
fan motor 18, an AC motor or a BLDC motor may be used by way of example. -
- Seating
grooves part 123. And, one ormore cooling holes 124 through which air for cooling thefan motor 18 is flowed are formed in the fanmotor seating part 120. - A vibration reduction part formed of elastic material that minimizes vibration in a state the
fan motor 18 is seated on the fanmotor seating part 120 is coupled to both sides of thefan motor 18. In the present embodiment, it will be explained that the vibration reduction part constitutes a portion of thefan motor 18. - The vibration reduction part includes a
first reduction part 182 that is coupled to the left side of thefan motor 18, and a second reduction part 184 (shown inFIG. 2 ) that is coupled to the right side of thefan motor 18. - Substantially, the
first reduction part 182 is seated on the first supporting part 122 and thesecond reduction part 184 is seated on the second supportingpart 123. - And, one or more supporting ribs 126 that support the
fan motor cover 19 are formed on the inner circumferential surface of the fanmotor seating part 120. - Meanwhile, the control
box seating part 130 is projected forward from theback surface part 110 of thechassis 11. - In other words, the control
box seating part 130 includes a plurality of extendingparts 130a that are substantially vertically extended forward based on theback surface part 110 and a connectingpart 130b that connects the front ends of the plurality of extendingparts 130a. -
- From a different point of view, the
space part 131 may be understood to be formed as the back surface part of thechassis 110 is collapsed forward. - And, the
pipe unit 165 positioned in the space part 13 and thespace part 131 are covered by the installpanel 40. - And, a side
surface opening part 132 through which thepipe unit 165 passes is formed at the extendingpart 130a adjacent to the fanmotor seating part 120, of the plurality of extendingparts 130a. - One or more reinforcing
ribs 133 that improve the strength of the controlbox seating part 130 are formed at the controlbox seating part 130. InFIG. 7 , a plurality of reinforcingribs 133 are formed at the back surface of the controlbox seating part 130 by way of example, wherein the plurality of reinforcingribs 133 are spaced vertically from each other. - The reinforcing
ribs 133 are formed over the plurality of extendingparts 130a and the connectingpart 130b. - Although the
pipe unit 165 positioned in thespace part 131 is bumped into the controlbox seating part 130 at the time of installation of thepipe unit 165, the breakage of the controlbox seating part 130 can be prevented by the reinforcingribs 133. - And, a
guide rib 135 that guides the seating of thecontrol box 20 is formed at the front surface part of the controlbox seating part 130. - Referring to
FIG. 7 , thepipe unit 165 connected to the heat-exchanger 16 is extended backward to theback surface part 110 of thechassis 11 and is bent on the upper of the fanmotor seating part 120, thereby being extended in right and left directions through the sidesurface opening part 132. - And, the
pipe unit 165 passing through the sidesurface opening part 132 is bent downward from thespace part 131. And, thepipe unit 165 is extended downward along thespace part 131, thereby being drawn out to the outside of themain body 10. - 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 controlbox seating part 130 so that themain body 10 does not require a space for avoiding thepipe unit 165, having advantages that product size becomes small and thefan motor 18 and thecontrol box 20 are easily installed. - In other words, since the
pipe unit 165 is positioned in the rear of thecontrol box 20 by passing through the upper of thefan motor 18, interference with thefan motor 18 disappears so that thefan motor 18 and thefan 17 can be positioned to be adjacent to each other at maximum, making it possible to reduce the entire size of the product. - Compared with the related art, when the
pipe unit 165 is positioned in front of thefan motor 18 or in front of thecontrol box 20, thefan motor 18 and thecontrol box 20 should be installed by avoiding thepipe unit 165 so that the entire size of themain body 10 becomes large and it is difficult to install thefan motor 18 and thecontrol box 20. However, with the present embodiment, these problems can be solved. -

engagement hook 196 that is engaged with thebox body 21 is formed at the top surface (or front surface) of thefan motor cover 19. - Therefore, in a state where the
fan motor 18 is received in themotor receiving space 121, the attaching/detachinghook 193 is primarily hanged by the hangingend 114 so that the position of thefan motor cover 19 can be fixed. And, thefirst engagement end 194 of thefan motor cover 19 is put on the top surface of anengagement part 125 formed at the second supportingpart 123 and thefan motor cover 19, specifically, thefirst covering part 192, covers the top side of thefirst reduction part 182. - If the
first covering part 192 covers thefirst reduction part 182 in a state where thefirst reduction part 182 is seated on the first supporting part 122, the moving of thefirst reduction part 182 can be prevented. - In other words, in the present embodiment, the
fan motor cover 19 allows one side of thefan motor 18, that is, the position of thefirst reduction part 182, to be fixed. - Meanwhile, the
fan 17 includes a plurality ofblades 172 that are spaced from each other and a connectingpart 174 that connects theblades 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. - A
shaft coupling part 175 that couples amotor shaft 181 of thefan motor 18 is formed at the connection part positioned on the outermost outside, of the connectingpart 174. And, ashaft coupling hole 176 is formed in theshaft coupling part 175. Theshaft coupling hole 176 is formed in the shape corresponding to themotor shaft 181. In other words, theshaft coupling hole 176 and themotor shaft 181 are formed in a non-circular shape, making it possible to prevent themotor shaft 181 from idling as to thefan 17. -
FIG. 11 is a perspective view of the box body according to the present embodiment, andFIG. 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. - Referring to

FIG. 13 is a perspective view showing a state where the fan motor is coupled to the fan. - Referring to
FIGS. 1 to 13 , the right side of thefan 17 is received in the second receivingpart 113 and the left side of thefan 17 is received in the first receivingpart 112. Then, themotor shaft 181 of thefan motor 18 penetrates through theshaft penetration hole 115 to allow themotor shaft 181 to be coupled to the right side of thefan 17. - More specifically, the
motor shaft 181 first penetrates through thesecond hole 115b and then themotor shaft 181 moves to thefirst hole 115a. And, thefan motor 18 is seated on the fanmotor seating part 120, while themotor shaft 181 moved to thefirst hole 115a being coupled to theshaft coupling part 175. - Since the first supporting part 122 is formed at the right side of the second receiving
part 113, themotor shaft 181 becomes short compared to that in the related art so that themotor shaft 181 straightly passes through thefirst hole 115a, being difficult to be coupled to theshaft coupling part 175. However, in the present embodiment, asecond hole 115b extended from thefirst hole 115a is additionally formed. Therefore, while themotor shaft 181 being moved to thefirst hole 115a after themotor shaft 181 first passes through thesecond hole 115b, if the coupling and of themotor shaft 181 and the seating of thefan motor 18 are performed, themotor shaft 181 can be coupled to theshaft coupling part 175. - If the
motor shaft 181 is coupled to thefan 17, thefirst reduction part 182 is seated on the first supporting part 122, thesecond reduction part 184 is seated on the second supportingpart 123, and a portion of thefan motor 18 is received nit ehmotor receiving space 121. Thereafter, thefan motor cover 19 covers thefan motor 18. Then, the attaching/detachinghook 193 is hanged by the hangingend 114 and thefirst covering part 192 covers thefirst reduction part 182. - Thereafter, the
control box 20 is seated on the controlbox seating part 130. Then, thesecond covering part 212 covers thesecond reduction part 184, theengagement hook 196 is hanged by thehook hanger 214, and thesecond engagement end 215 is put on the top surface of thefirst engagement end 194. - And, the engagement member allows the
second engagement end 214, the first engagement end 195, and theengagement part 125 to be simultaneously engaged. - 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.
- 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.
- 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.

pressing part 302 that selectively presses theswitch 218 is projected backward from the back surface of thefront panel 30, and apenetration hole 148 through which thepressing part 302 is selectively penetrated is formed in thefront frame 14. Thepenetration hole 148 is positioned downward theservice hole 143. - Referring to
FIG. 10 , thepressing part 302 presses theswitch 218 by penetrating through thepenetration hole 148 in a state where thefront panel 30 is closed. Theswitch 218 is for sensing the state where thefront panel 30 is closed. If theswitch 218 is pressed, theswitch 218 is turned on and the turn-on signal of theswitch 218 is transmitted to the controller not shown. Then, the controller operates the dust collector and/or the plasma filter. - 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 thefront panel 30 is sensed, the controller operates the dust collector and/or the plasma filter. - 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.
- 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.
