  A conventional electric dust collector (in particular, see Patent Document 2) includes a charging unit and a dust collecting unit. The charging unit has a discharge electrode having a high voltage potential and a counter electrode having a ground potential, and gives a charge to fine particles in the air passing therethrough. The dust collection unit has a high voltage electrode having a high voltage potential and a counter electrode having a ground potential, and collects the fine particles by the generated electrostatic force.

  The high-voltage electrode of the dust collecting part is composed of a large number of electrodes that are vertically long plate-like members. These many electrodes are provided at regular intervals in the left-right direction. The counter electrode of the dust collecting portion is also composed of a number of electrodes that are vertically long plate-like members. These many electrodes are arranged in the left-right direction so as to be alternately arranged at a predetermined interval with the counter electrode of the dust collecting portion.

  There is a problem that the “predetermined interval” is not uniform.

  A conventional electrostatic precipitator has a power supply component. The conventional electrostatic precipitator further includes a pair of terminals that electrically connect the dust collector to the power supply component.

  Since a large space is required to store the power supply component and the terminal, there is a problem that it is difficult to reduce the size of the electric dust collector.

  There is also a problem that the electrostatic precipitator is not detachable or the electric precipitator is not easy to attach and detach because the electric connection between the electrostatic precipitator and the indoor unit is troublesome.

  Since the power supply component is located in the air path, there is also a problem that the efficiency of the air conditioner decreases.

  A conventional electrostatic precipitator (particularly, see Patent Document 4) is disposed near a heat exchanger, such as above a heat exchanger provided in an indoor unit.

  Therefore, there is a problem that condensation may occur in the electric dust collector. There is also a problem that the electrostatic precipitator obstructs the air flow.

  An object of the present invention is to reduce the size of an air cleaning device.

An air cleaning device according to one aspect of the present invention is provided.

  In the present invention, the first terminal and the second terminal are one end in the first direction in which the plurality of first plate electrodes and the plurality of second plate electrodes are arranged, the first direction, and the first connecting member. It attaches to the position away in the 3rd direction orthogonal to both the 2nd direction which a 2nd connection member overlaps. Thereby, a 1st terminal and a 2nd terminal can be arrange | positioned in a small space. Therefore, the air cleaning device can be reduced in size.

Embodiment 1 FIG.
The configuration of the device according to the present embodiment and the operation of the device according to the present embodiment will be described in order. Thereafter, details of the present embodiment and effects of the present embodiment will be described in order.

*** Explanation of configuration ***
With reference to FIG. 1, the structure of the indoor unit 100 of the air conditioner which is an apparatus which concerns on this Embodiment is demonstrated.

  As shown in FIG. 1, an indoor unit 100 of an air conditioner includes an indoor unit main body 110, a blower fan 120, heat exchangers 131, 132, 133, a filter 140, a front panel 150, and a vertical wind direction variable vane. 160, an air cleaning device 200, and a filter cleaning device 300.

  The indoor unit main body 110 is a frame of an air conditioner. The indoor unit main body 110 houses the blower fan 120, the heat exchangers 131, 132, 133, the filter 140, the air cleaning device 200, and the filter cleaning device 300. In this Embodiment, the indoor unit main body 110 accommodates the filter 140 and the air purifying apparatus 200 so that attachment or detachment is possible.

  A front panel 150 is attached to the front surface of the indoor unit main body 110 so as to be freely opened and closed. On the upper surface side of the indoor unit main body 110, a suction port 111 for sucking air from the room where the indoor unit 100 of the air conditioner is installed is provided. On the lower surface side of the indoor unit main body 110, a blowout port 112 for blowing air into the room is provided. A vertical vane direction variable vane 160 is rotatably attached to the outlet 112. Although not shown, a left and right airflow direction variable vane is also rotatably attached to the back of the outlet 112.

  The up-and-down air direction variable vane 160 adjusts the up-and-down direction of the airflow blown out from the outlet 112. The left and right airflow direction variable vanes adjust the left and right directions of the airflow blown from the air outlet 112.

  The blower fan 120 is installed inside the indoor unit main body 110. The blower fan 120 sucks air and blows out the sucked air. In the present embodiment, the blower fan 120 is a cross flow fan. The blower fan 120 can be changed to a plurality of propeller fans. The plurality of propeller fans are arranged side by side in the left-right direction of the indoor unit main body 110. The number of propeller fans is preferably 2-4. Each propeller fan may be an axial flow fan or a mixed flow fan.

  The heat exchangers 131, 132, and 133 are disposed in the air path formed by the blower fan 120. The heat exchanger 131 is a portion corresponding to the upper stage of the heat exchanger divided into an upper stage and a lower stage. The heat exchanger 131 is also a portion corresponding to the front side of the heat exchanger divided into the front side and the back side. The heat exchanger 132 is a portion corresponding to the lower stage of the heat exchanger divided into an upper stage and a lower stage. The heat exchanger 133 is a part corresponding to the back side of the heat exchanger divided into the front side and the back side. In the present embodiment, such an upper heat exchanger 131 on the front side, a lower heat exchanger 132 on the front side, and a heat exchanger 133 on the rear side are connected to the air outlet 111 of the indoor unit body 110 from the air outlet. It is arranged so as to surround the blower fan 120 in the air path leading to 112. Note that the heat exchanger 133 on the back side may be omitted, and only the upper and lower heat exchangers 131 and 132 may be employed. Or you may employ | adopt the heat exchanger of another structure.

  The front-side upper heat exchanger 131, the front-side lower heat exchanger 132, and the rear-side heat exchanger 133 each exchange heat between air and the refrigerant. This air is mainly sucked from the suction port 111 by the blower fan 120. The front-side upper heat exchanger 131, the front-side lower heat exchanger 132, and the rear-side heat exchanger 133 each cool or heat or dehumidify the air by exchanging heat.

  A drain pan 113 for collecting condensed water is disposed below the heat exchanger 132 on the lower front side. A drain pan 114 is also disposed below the heat exchanger 133 on the back side. The drain pans 113 and 114 are formed as a part of the indoor unit main body 110.

  The filter 140 is disposed between the suction port 111 of the indoor unit main body 110 and the heat exchangers 131 and 133 on the front side upper stage and the rear side so as to cover the entire suction port 111. In the present embodiment, the number of filters 140 is two. The filter 140 is arranged separately on the left and right. Each filter 140 captures dust in the air. This air is mainly sucked from the suction port 111 by the blower fan 120.

  The filter cleaning device 300 is disposed between the heat exchangers 131 and 132 on the front side upper stage and the front side lower stage and the front panel 150. The filter cleaning device 300 is installed for each filter 140. Therefore, in the present embodiment, the number of filter cleaning devices 300 is two. The filter cleaning device 300 automatically cleans the filter 140.

  The number of filters 140 can be changed as appropriate. The number of filter cleaning devices 300 can be changed according to the number of filters 140. That is, when only one filter 140 is used, one filter cleaning device 300 is installed. When three or more filters 140 are used, three or more filter cleaning apparatuses 300 are installed.

  The filter cleaning device 300 includes a device main body 310 and a dust box 320.

  The apparatus main body 310 accommodates the filter 140 movably.

  The dust box 320 is detachably attached to the front surface of the apparatus main body 310. The dust box 320 stores the dust captured by the filter 140.

  The indoor unit main body 110 houses the air cleaning device 200 behind the dust box 320. Therefore, an insertion port 311 into which both the air cleaning device 200 and the dust box 320 are inserted is provided on the front surface of the apparatus main body 310. The air cleaning device 200 is inserted into the insertion port 311 so that the longitudinal direction of the air cleaning device 200 is horizontal. After being inserted into the insertion port 311, the air cleaning device 200 is moved downward, so that it is electrically connected to a power feeding terminal described later and is attached to the indoor unit main body 110. Even in this state, the air cleaning device 200 is oriented so that the longitudinal direction of the air cleaning device 200 is horizontal. The air cleaning device 200 is moved upward to release the electrical connection with the terminal. The air purifier 200 is taken out of the indoor unit body 110 from the insertion port 311 after the electrical connection is released.

  The air purifier 200 is installed in a space between the suction port 111 of the indoor unit main body 110 and the heat exchangers 131 and 132 on the front side upper stage and the front side lower stage. In other words, the air cleaning device 200 is disposed on the upstream side of the heat exchangers 131 and 132 on the front side upper stage and the front side lower stage in the air path formed by the blower fan 120. In the present embodiment, the number of air cleaning devices 200 is one. The air purifier 200 is installed only on the left side. The air cleaning device 200 cleans the air that has passed through the filter 140. It is desirable that the size of the air cleaning device 200 in the left-right direction is the same as the size of the filter 140 in the left-right direction. In addition, if the difference between the size in the left-right direction of the air cleaning device 200 and the size in the left-right direction of the filter 140 is within 6 centimeters, it can be said that the size is the same.

  The number of the air cleaning devices 200 can be changed as appropriate. The air cleaning device 200 may be installed on both the left and right sides.

  In the present embodiment, the indoor unit main body 110 is configured to clean the air by setting the center position in the height direction of the air purifier 200 to a position lower than the connection part 134 between the upper heat exchanger 131 and the lower heat exchanger 132. The device 200 is stored. For this reason, it is hard for the air purifying apparatus 200 to obstruct the flow of air. Moreover, it is easy to attach and detach the air cleaning device 200. The height direction of the air cleaning device 200 is the vertical direction of the air cleaning device 200.

  The indoor unit main body 110 stores the air cleaning device 200 in front of the heat exchangers 131 and 132, away from the heat exchangers 131 and 132. For this reason, metal parts, such as a terminal mentioned later, of the air purifying apparatus 200 are hard to cool. Moreover, the dew condensation water of the heat exchangers 131 and 132 does not flow into the air cleaning device 200. Therefore, condensation is unlikely to occur in the air cleaning device 200.

  In the present embodiment, the indoor unit 100 of the air conditioner further includes a restriction unit 170.

  The restricting unit 170 restricts a range in which the air purifying device 200 can enter in the depth direction of the indoor unit main body 110 in order to prevent contact between the air purifying device 200 and the heat exchangers 131 and 132. The depth direction of the indoor unit body 110 is the front-rear direction of the indoor unit body 110.

  The air cleaning device 200 includes a charging unit 210, a dust collection unit 220, and a frame unit 230.

  The charging unit 210 charges particles in the air. This air is mainly sucked from the suction port 111 by the blower fan 120 and then passed through the filter 140. Specifically, the particles in the air are bacteria, molds, viruses and the like that exist in the air.

  The dust collection unit 220 collects particles charged by the charging unit 210 by electrostatic force. The electrostatic force is an electric field or an electric field.

  The frame unit 230 fixes the charging unit 210 and the dust collection unit 220.

*** Explanation of operation ***
The operation of the air conditioner according to the present embodiment will be described.

  Although not shown, when the power is turned on, the compressor compresses and discharges the refrigerant in the outdoor unit of the air conditioner.

  In the indoor unit 100 of the air conditioner, the refrigerant discharged from the compressor flows into the heat exchangers 131, 132, and 133. When the blower fan 120 rotates, the room air sucked from the suction port 111 is subjected to heat exchange with the refrigerant by the heat exchangers 131, 132, and 133 after dust is removed through the filter 140. At this time, the air that passes through the heat exchangers 131, 132, and 133 from the upstream to the downstream is cleaned by the air cleaning device 200.

  The room air heat-exchanged by the heat exchangers 131, 132, and 133 is blown out into the room from the air outlet 112. At this time, air is blown out in a direction corresponding to the angle of the up / down air direction variable vane 160 and the left / right air direction variable vane. The user of the air conditioner can set the angles of the up-and-down air direction variable vane 160 and the left and right air direction variable vanes manually or with a remote controller. Although not shown, when the air conditioner indoor unit 100 includes an infrared sensor, the air conditioner indoor unit 100 automatically detects the temperature distribution in the room, the position of the person, etc. It is also possible to adjust the angles of the wind direction variable vane 160 and the left and right wind direction variable vanes.

  The series of operations described above are repeated. As a result, the room air is continuously cooled or warmed by removing dust. Thereby, indoor air quality changes.

*** Detailed explanation ***
Details of the present embodiment will be described.

  The configuration of the air cleaning device 200 will be described with reference to FIGS.

  FIG. 2 is a view of the air cleaning device 200 as viewed from the upper front side. FIG. 3 is a view of the air cleaning device 200 as viewed from the diagonally lower side on the front side. FIG. 4 is a view of the air cleaning device 200 as viewed from directly below. FIG. 5 is a view showing a cross section of the air cleaning device 200 taken along line AA of FIG. FIG. 6 is a diagram of the disassembled air cleaning device 200 as viewed from the upper front side. In FIG. 7, it is the figure which looked at the air purifying apparatus 200 from which the upper frame 231 mentioned later was removed from right above. FIG. 8 is a view of only a lower frame 232, which will be described later, seen from directly above.

  As described above, the air cleaning device 200 includes the charging unit 210, the dust collection unit 220, and the frame unit 230. The air cleaning device 200 further includes a prefilter 240.

  The pre-filter 240 captures dust that has not been captured by the filter 140.

  The charging unit 210 is disposed below the prefilter 240, that is, downstream of the prefilter 240. The charging unit 210 includes a discharge electrode 211 and a counter electrode 212.

  The discharge electrode 211 includes a pair of ring terminals 213, a pair of tubes 214, and a wire 215. The ring terminal 213 is connected to both ends of the wire 215. The tube 214 is put on a connection portion between the ring-shaped terminal 213 and the wire 215. A spring 216 is hooked on one ring-shaped terminal 213.

  The counter electrode 212 is composed of a plurality of flat electrodes 217. The plurality of flat electrodes 217 are arranged in the third direction D3 at intervals. The third direction D3 will be described later. A wire 215 passes between adjacent flat electrodes 217. In the present embodiment, the number of flat electrodes 217 is three. Therefore, the wire 215 is folded after passing between the flat plate electrode 217 at one end in the third direction D3 and the flat plate electrode 217 in the middle of the third direction D3, and the intermediate flat plate electrode 217 in the third direction D3. It passes between the flat electrode 217 at the other end in the third direction D3.

  Note that the number of the plate-like electrodes 217 can be changed as appropriate. The number of turns of the wire 215 can be changed according to the number of the flat electrodes 217.

  The charging unit 210 generates an electric field by applying different voltages to the discharge electrode 211 and the counter electrode 212. The charging unit 210 charges particles in the air that pass through the electric field.

  The voltage applied to the discharge electrode 211 is a high voltage. Specifically, a voltage of 6000 volts is applied to the discharge electrode 211. The voltage applied to the counter electrode 212 is a low voltage. Specifically, a voltage of 0 volts is applied to the counter electrode 212. That is, the counter electrode 212 is grounded.

  The dust collection unit 220 is disposed below the charging unit 210, that is, downstream of the charging unit 210. The dust collection unit 220 includes a first electrode 221 and a second electrode 222.

  The first electrode 221 is provided with a plurality of first plate electrodes 223 and a first connecting member 225. The plurality of first plate electrodes 223 are arranged in the first direction D1 at intervals. In the present embodiment, the first direction D1 is the left-right direction of the air cleaning device 200. When the air cleaning device 200 is housed in the indoor unit main body 110, the left-right direction of the air cleaning device 200 coincides with the left-right direction of the indoor unit main body 110. In the present embodiment, the number of first plate electrodes 223 is 37. The first connecting member 225 connects the plurality of first plate electrodes 223. Thereby, in the 1st electrode 221, the some 1st plate-shaped electrode 223 is provided integrally.

  A first terminal 227 is attached to one end of the first electrode 221 in the first direction D1. Specifically, the first terminal 227 is attached to the right end of the first electrode 221.

  The second electrode 222 is provided with a plurality of second plate electrodes 224 and a second connecting member 226. The plurality of second plate electrodes 224 are alternately arranged with a plurality of first plate electrodes 223 at intervals. That is, the plurality of second plate-like electrodes 224 are arranged in the first direction D1 at intervals from each other, like the plurality of first plate-like electrodes 223. In the present embodiment, the number of second plate electrodes 224 is 38, one more than the plurality of first plate electrodes 223. The second connecting member 226 connects the plurality of second plate electrodes 224. Thereby, in the second electrode 222, a plurality of second plate electrodes 224 are integrally provided. The second connecting member 226 overlaps the first connecting member 225 in the second direction D2. The second direction D2 is a direction orthogonal to the first direction D1. In the present embodiment, the second direction D2 is the vertical direction of the air cleaning device 200. When the air cleaning device 200 is stored in the indoor unit main body 110, the vertical direction of the air cleaning device 200 coincides with the vertical direction of the indoor unit main body 110.

  A second terminal 228 is attached to one end of the second electrode 222 in the first direction D1. Specifically, the second terminal 228 is attached to the right end of the second electrode 222. The second terminal 228 is attached at a position away from the first terminal 227 in the third direction D3. The third direction D3 is a direction orthogonal to both the first direction D1 and the second direction D2. In the present embodiment, the third direction D3 is the front-rear direction of the air cleaning device 200. When the air cleaning device 200 is housed in the indoor unit main body 110, the front-rear direction of the air cleaning device 200 coincides with the front-rear direction of the indoor unit main body 110.

  As described above, the air cleaning device 200 is disposed in front of the heat exchangers 131 and 132 and at a position away from the heat exchangers 131 and 132. In this position, air flows vertically. In addition, as described above, the air cleaning device 200 is attached to the indoor unit main body 110 such that the longitudinal direction of the air cleaning device 200 is horizontal. The direction in which the plate surface of the plate-like electrode 217 extends, the direction in which the plate surface of the first plate-like electrode 223 extends, and the direction in which the plate surface of the second plate-like electrode 224 extend are all in the second direction D2. When the apparatus 200 is mounted on the indoor unit main body 110, the direction in which the plate surface of the plate electrode 217 extends, the direction in which the plate surface of the first plate electrode 223 extends, and the direction in which the plate surface of the second plate electrode 224 extends are as follows. , Both become vertical. That is, when the air cleaning device 200 is mounted on the indoor unit main body 110, the plate surface of the plate electrode 217, the plate surface of the first plate electrode 223, and the plate surface of the second plate electrode 224 are all air. It extends along the flowing direction. For this reason, the plate-like electrode 217, the first plate-like electrode 223, and the second plate-like electrode 224 are unlikely to obstruct the air flow, and the efficiency of the air conditioner increases.

  The number of first plate electrodes 223 can be changed as appropriate. The number of second plate electrodes 224 can be changed according to the number of first plate electrodes 223.

  The dust collection unit 220 generates electrostatic force by applying different voltages to the first electrode 221 and the second electrode 222 via the first terminal 227 and the second terminal 228, respectively. The dust collection unit 220 collects particles charged by the charging unit 210 by the electrostatic force.

  The voltage applied to the first electrode 221 is a high voltage. Specifically, a voltage of 6000 volts is applied to the first electrode 221. The voltage applied to the second electrode 222 is a low voltage. Specifically, a voltage of 0 volts is applied to the second electrode 222. That is, the second electrode 222 is grounded.

  As described above, the voltage applied to the first electrode 221 of the dust collection unit 220 is the same as the voltage applied to the discharge electrode 211 of the charging unit 210. Therefore, in the present embodiment, the first terminal 227 of the dust collection unit 220 and the ring-shaped terminal 213 of the charging unit 210 are electrically connected. Specifically, a pair of notches 229 is provided in the first terminal 227 of the dust collection unit 220. One ring-shaped terminal 213 of the charging unit 210 is hooked on one notch 229. A spring 216 that is hooked on the other ring-shaped terminal 213 of the charging unit 210 is hooked on the other notch 229. Thereby, a voltage can be applied to the first electrode 221 of the dust collection unit 220 and the discharge electrode 211 of the charging unit 210 from a common power source.

  In addition, the voltage applied to the second electrode 222 of the dust collection unit 220 is the same as the voltage applied to the counter electrode 212 of the charging unit 210. Therefore, in the present embodiment, the second electrode 222 of the dust collection unit 220 and the counter electrode 212 of the charging unit 210 are integrally formed. That is, the second terminal 228 of the dust collection unit 220 is also used as a terminal for applying a voltage to the counter electrode 212 of the charging unit 210. Thereby, a voltage can be applied to the second electrode 222 of the dust collection unit 220 and the counter electrode 212 of the charging unit 210 from a common power source. In addition, the number of parts can be reduced. The second electrode 222 of the dust collection unit 220 and the counter electrode 212 of the charging unit 210 may be formed separately. In this case, the second electrode 222 of the dust collection unit 220 and the counter electrode 212 of the charging unit 210 may be electrically connected to each other, or may be separately fed.

The first electrode 221 is formed of an antistatic resin having electrical conductivity and a resistance value of 10 ¹¹ Ω / cm ² (ohms per square centimeter) or less. The second electrode 222 is formed by applying metal plating to a resin. The second electrode 222 may be formed of a metal plate such as stainless steel, or may be formed of a conductive resin having a resistance value of 10 ³ Ω / cm ² or less kneaded with carbon. The first terminal 227 attached to the first electrode 221 and the second terminal 228 attached to the second electrode 222 are made of metal. The ring-shaped terminal 213, the wire 215, and the spring 216 of the discharge electrode 211 are also formed of metal. The tube 214 of the discharge electrode 211 has a two-layer structure of an outer layer that is a resin and an inner layer that is an adhesive.

  In the present embodiment, the first terminal 227 extends from one end of the first electrode 221 in the first direction D1 within a range of both ends of the first electrode 221 in the third direction D3. That is, the first terminal 227 does not protrude from both sides of the first electrode 221 in the third direction D3. Similarly, the second terminal 228 extends from one end of the second electrode 222 in the first direction D1 within a range of both ends of the second electrode 222 in the third direction D3. That is, the second terminal 228 does not protrude from both sides of the second electrode 222 in the third direction D3. For this reason, the magnitude | size of the air purifying apparatus 200 in the 3rd direction D3 can be made small.

  The first terminal 227 is attached to a first power feeding unit 273 provided at one end of the first electrode 221 in the first direction D1. The 1st electric power feeding part 273 is extended in the outer side of the 1st direction D1 from the position away from the edge | side in the both ends of the 3rd direction D3 in the end surface of the 1st direction D1 of the 1st electrode 221. In the present embodiment, the right end surface of the first electrode 221 has a rectangular shape including two long sides and two short sides, and the two short sides correspond to the sides at both ends in the third direction D3. . That is, in the present embodiment, the first power feeding unit 273 extends to the right side from a position other than the short side on the right end surface of the first electrode 221. Therefore, the voltage applied through the first terminal 227 is not the short side of the right end surface of the first electrode 221 but the position of the first electrode 221 from a position away from the short side of the right end surface of the first electrode 221. Applied to the right end face. Therefore, the bias of the voltage applied to the front side and the back side of the first electrode 221 can be reduced. That is, the potential distribution in the third direction D3 of the first electrode 221 can be made to be uniform.

  The second terminal 228 is attached to a second power feeding unit 274 provided at one end of the second electrode 222 in the first direction D1. One end of the first electrode 221 provided with the first power feeding unit 273 in the first direction D1 is located outside the first direction D1 of one end of the second electrode 222 in the first direction D1. The second power feeding unit 274 extends from one end surface of the second electrode 222 in the first direction D1 to the outside of the first direction D1, and is positioned away from one end of the first electrode 221 in the first direction D1 in the second direction D2. Pass through. In the present embodiment, the right end that is one end of the first electrode 221 in the first direction D <b> 1 is formed by the right end of the first connecting member 225. Further, the right end, which is one end of the second electrode 222 in the first direction D1, is formed by the rightmost second plate electrode 224, the right end of the second connecting member 226, and the right end of the counter electrode 212. A gap 275 is formed between the right end of the first connecting member 225 and the first plate electrode 223 on the rightmost side. The rightmost second plate electrode 224 is inserted into the gap 275 so that the right end of the first connecting member 225 is on the right side of the rightmost second plate electrode 224. That is, the right end of the first electrode 221 is on the outer side in the left-right direction of the air cleaning device 200 than the right end of the second electrode 222. The second power feeding unit 274 extends to the right from at least one of the plate surface of the second plate electrode 224 on the rightmost side and the right end surface of the second connecting member 226, and passes over the right end of the first connecting member 225. . That is, in the present embodiment, the second power feeding unit 274 extends from the right end surface of the second electrode 222 to the outside in the left-right direction of the air cleaning device 200, and extends from the right end of the first electrode 221 in the vertical direction of the air cleaning device 200. Pass away. Therefore, the first terminal 227 is not connected to the front surface of the first electrode 221 or the second terminal 228 is not connected to the front surface of the second electrode 222, and the second terminal 228 is connected to the right end surface of the second electrode 222. The first terminal 227 can be connected to the right end surface of the first electrode 221 while being connected. Therefore, the size of the air cleaning device 200 in the third direction D3 can be reduced.

  Note that since the first electrode 221 is formed of an antistatic resin, no spark is generated even if the second power feeding portion 274 passes near the right end of the first electrode 221. Therefore, the size of the air cleaning device 200 in the second direction D2 can be reduced by adopting a configuration in which the second power feeding unit 274 passes through the vicinity of the right end of the first electrode 221.

  The first terminal 227 includes a first extending portion 251, a first curved portion 253, a first end portion 255, a third curved portion 257, and a pair of standing portions 258. The first extending portion 251 is a portion extending from one end of the first electrode 221 in the first direction D1. The first curved portion 253 is a portion that bends from the first extending portion 251 in the third direction D3. The first end portion 255 is a portion extending from the first music portion 253. The first end portion 255 has a flat plate shape having a thickness in the first direction D1. The first end portion 255 has a power feeding plate surface 271. The third curved portion 257 is a portion that bends from the upper end of the first end portion 255 in the first direction D1. The standing portion 258 is a portion that rises from the third music portion 257. Each of the standing portions 258 is provided with the notch 229 described above.

  The second terminal 228 has a second extending portion 252, a second curved portion 254, and a second end portion 256. The second extending part 252 is a part extending from one end of the second electrode 222 in the first direction D1. The second curved portion 254 is a portion that bends from the second extending portion 252 in the second direction D2. The second end portion 256 is a portion extending from the second music portion 254. The second end portion 256 has a flat plate shape having a thickness in the first direction D1. The second end portion 256 has a power feeding plate surface 272. The second end portion 256 is arranged in the first direction D1 at a distance from the first end portion 255. This interval is desirably wide so that tracking does not occur even when a water droplet enters the inside of the air cleaning device 200, and specifically, a width of 2 centimeters or more is desirable.

  The frame unit 230 includes an upper frame 231 and a lower frame 232.

  As described above, the air cleaning device 200 is disposed in front of the heat exchangers 131 and 132 and at a position away from the heat exchangers 131 and 132. In this position, air flows vertically. In addition, as described above, the air cleaning device 200 is attached to the indoor unit main body 110 such that the longitudinal direction of the air cleaning device 200 is horizontal. The direction in which the front surface and the back surface of the upper frame 231 extend and the direction in which the front surface and the back surface of the lower frame 232 extend are both in the second direction D2. Therefore, when the air cleaning device 200 is mounted on the indoor unit main body 110, the direction in which the front and back surfaces of the upper frame 231 extend and the direction in which the front and back surfaces of the lower frame 232 extend are both perpendicular. That is, when the air cleaning device 200 is mounted on the indoor unit main body 110, the front and back surfaces of the upper frame 231 and the front and back surfaces of the lower frame 232 both extend along the direction in which air flows. For this reason, it becomes difficult for the outer frame of the upper frame 231 and the outer frame of the lower frame 232 to obstruct the air flow, and the efficiency of the air conditioner increases. Further, since the back surface of the upper frame 231 and the back surface of the lower frame 232 are vertical surfaces, the air cleaning device 200 can be stored compactly in front of the heat exchangers 131 and 132. That is, the space behind the indoor unit main body 110 can be effectively used.

  A handle 233 is provided on the front surface of the upper frame 231. An opening 234 is provided on the upper surface of the upper frame 231. The pre-filter 240 is fitted in the opening 234.

  Ribs 235 and openings 236 are provided on the lower surface of the lower frame 232. There is a slit 237 on the upper surface of the rib 235. In the present embodiment, the slit 237 does not penetrate in the second direction D2. That is, the slit 237 is a groove having a bottom surface. The opening 236 is at least partially divided by the rib 235. In the present embodiment, the opening 236 is completely divided by the rib 235. That is, the rib 235 crosses the opening 236. The transverse direction of the rib 235 is the third direction D3. In the present embodiment, the number of ribs 235 is one.

  Of the plurality of first plate electrodes 223, at least a part of any one of the first plate electrodes 223 fits into the slit 237 of the rib 235. The opening 236 exposes the remaining first plate electrode 223 among the plurality of first plate electrodes 223 on both sides of the rib 235. In the present embodiment, among the plurality of first plate electrodes 223, at least a part of the first plate electrode 223 at the center fits into the slit 237 of the rib 235. Specifically, the lower end portion of the central first plate electrode 223 fits into the slit 237 of the rib 235. Thereby, the first electrode 221 is positioned.

  As described above, in the dust collector 220, the plurality of second plate electrodes 224 are alternately arranged with a plurality of first plate electrodes 223 at intervals. Therefore, the opening 236 further exposes the plurality of second plate electrodes 224 on both sides of the rib 235.

  The plate-like electrode that fits into the slit 237 of the rib 235 is not limited to the first plate-like electrode 223 but may be the second plate-like electrode 224.

  Further, the number of ribs 235 can be changed as appropriate. When two ribs 235 are provided, at least a part of the two first plate electrodes 223 may fit into the slits 237 of the two ribs 235, respectively, At least a portion and at least a portion of one second plate-like electrode 224 may fit into the slits 237 of the two ribs 235, respectively, or at least a portion of each of the two second plate-like electrodes 224 may be two each. You may fit in the slit 237 of the rib 235.

  The slit 237 may penetrate in the second direction D2. That is, the slit 237 may be a hole without a bottom surface. Regardless of whether the slit 237 is a groove or a hole, the slit 237 has two inner wall surfaces.

  When both inner wall surfaces of the slit 237 are flat, the interval between the inner wall surfaces needs to be the same as the thickness of the plate electrode to be inserted or larger than the thickness of the plate electrode to be inserted. If the distance is the same as the thickness of the plate electrode, the plate electrode can be fixed by sandwiching the plate electrode between both inner wall surfaces.

  When one inner wall surface of the slit 237 is flat but there is one or more protrusions on the other inner wall surface, the interval between the protrusions on one inner wall surface and the other inner wall surface is the plate electrode to be inserted It is necessary to be equal to the thickness of the plate electrode or larger than the thickness of the plate electrode to be inserted. If the distance is the same as the thickness of the plate-like electrode, the plate-like electrode can be fixed by sandwiching the plate-like electrode between the projections of one inner wall surface and the other inner wall surface.

  When both inner wall surfaces of the slit 237 are not flat and there are one or more protrusions on both inner wall surfaces, the distance between the protrusion on one inner wall surface and the protrusion on the other inner wall surface is inserted. It is necessary to be equal to the thickness of the plate electrode or larger than the thickness of the plate electrode to be inserted. If the distance is the same as the thickness of the plate-like electrode, the plate-like electrode can be fixed by sandwiching the plate-like electrode between the projections of both inner wall surfaces.

  In the present embodiment, there is a protrusion 238 on one side of the rib 235. Of the plurality of second plate electrodes 224, the side surface of one of the second plate electrodes 224 hits the protrusion 238. In the present embodiment, the side surface of the second plate electrode 224 adjacent to the left side of the central first plate electrode 223 hits the protrusion 238 on one side surface of the rib 235. Thereby, the second electrode 222 is also positioned.

  It is desirable that the protrusions 238 on one side of the rib 235 be at least two places on one side of the rib 235. In the present embodiment, there are two protrusions 238 on one side of the rib 235.

  In the present embodiment, a protrusion 239 is provided on the other side surface of the rib 235 in the same manner as one side surface of the rib 235. Of the plurality of second plate electrodes 224, the side surface of any other second plate electrode 224 hits the protrusion 239. In the present embodiment, the side surface of the second plate electrode 224 adjacent to the right side of the central first plate electrode 223 hits the protrusion 239 on the other side surface of the rib 235. Thereby, the 2nd electrode 222 is positioned reliably.

  It is desirable that the protrusions 239 on the other side surface of the rib 235 are also at least two places on the other side surface of the rib 235. In the present embodiment, there are two protrusions 239 on the other side of the rib 235.

  The frame part 230 further has an intermediate frame 259.

  The middle frame 259 is fitted to one end side in the first direction D1 on the upper surface of the lower frame 232. Specifically, the middle frame 259 covers the lower frame 232 so as to cover from the edge of the opening 236 to one end of the lower frame 232 in the first direction D1. As a result, the first terminal 227 and the second terminal 228 are covered with the middle frame 259.

  Although not shown, a convex portion is provided on the lower surface of the middle frame 259. This convex portion closes the space between the first end portion 255 of the first terminal 227 and the second end portion 256 of the second terminal 228 arranged in the first direction D1. Thereby, even if a water droplet enters the inside of the air cleaning device 200, it is possible to prevent tracking from occurring between the first terminal 227 and the second terminal 228.

  In the present embodiment, the lower frame 232 has a first hole 261 through which the first end 255 of the first terminal 227 penetrates in the second direction D2, and a second end 256 of the second terminal 228 in the second direction. A second hole 262 penetrating through D2 is provided. The second hole 262 is separated from the first hole 261. As described for the distance between the first end portion 255 and the second end portion 256, it is desirable that the distance between the first hole 261 and the second hole 262 be wide so that tracking does not occur.

  The lower frame 232 is further provided with a groove 263 connected to the first hole 261 and separated from the second hole 262. The first extending portion 251 of the first terminal 227 is fitted into the groove 263. In the present embodiment, the first curved portion 253 of the first terminal 227 penetrates the first hole 261 together with the first end portion 255, but may be fitted in the groove 263 together with the first extending portion 251.

  On the lower surface of the lower frame 232, a first restriction portion 277 that is a partition wall is provided in front of the first hole 261. In front of the second hole 262, a second restricting portion 278 having a wall surface in the third direction D3 and having the same partition as the first restricting portion 277 is provided. The functions of the first restriction unit 277 and the second restriction unit 278 will be described later.

  The configuration of the filter cleaning device 300 will be described with reference to FIGS. 9 to 23.

  As described above, the filter cleaning device 300 includes the device main body 310 and the dust box 320.

  As shown in FIG. 9, a power supply unit 400 is fixed to the lower front portion of the apparatus main body 310. The power supply unit 400 applies a voltage for generating an electrostatic force to the dust collection unit 220 of the air cleaning device 200.

  As described above, in the present embodiment, the indoor unit 100 of the air conditioner further includes the power supply unit 400. The indoor unit main body 110 houses the power supply unit 400 in the lower part of the front surface.

  FIG. 10 is a diagram showing the filter cleaning device 300 with the left dust box 320 removed.

  A part of the apparatus main body 310 forms a support portion 500. The support unit 500 supports the air cleaning device 200.

  As described above, in the present embodiment, the indoor unit 100 of the air conditioner further includes the support unit 500. The indoor unit main body 110 accommodates the support unit 500 and also supports and stores the air cleaning device 200 by the support unit 500.

  Another part of the apparatus main body 310 forms a main receiving portion 315. The main receiving portion 315 supports the dust box 320.

  Still another part of the apparatus main body 310 forms a limiting portion 170 that is a partition wall. As described above, the restriction unit 170 restricts the range in which the air cleaning device 200 can enter in the depth direction of the indoor unit main body 110. In the present embodiment, restriction unit 170 has a structure that restricts not only the depth direction of indoor unit body 110 but also the range in which air purifier 200 can move in the left-right direction of indoor unit body 110. The apparatus main body 310 is also provided with a mechanism that limits the range in which the filter 140 can move in the left-right direction of the indoor unit main body 110. The limiting part 170 is located below this mechanism. It is desirable that the range in which the movement of the filter 140 is restricted by this mechanism and the range in which the movement of the air cleaning device 200 is restricted by the restriction unit 170 are the same. That is, it is desirable that the restriction unit 170 restricts the range in which the air cleaning device 200 can move in the left-right direction of the indoor unit body 110 to the same range as the range in which the filter 140 can move in the left-right direction of the indoor unit body 110. If the size of the filter 140 in the left-right direction is the same as the size of the air cleaning device 200 in the left-right direction, the air passing through the filter 140 can be efficiently obtained by matching the position of the filter 140 with the position of the air cleaning device 200. Can be passed through the air cleaning device 200. Further, by arranging the right end of the mechanism, which is an obstacle for wind flowing vertically, and the right end of the restricting portion 170 in the vertical direction, the range in which the obstacle exists in the horizontal direction can be reduced.

  At least a part of the power supply unit 400 is disposed directly below the support unit 500. Thereby, the wiring from the power supply part 400 mentioned later to the support part 500 can be shortened. Since a high voltage is applied from the power supply unit 400 to the dust collection unit 220 of the air cleaning device 200, wiring with an expensive cable is required. Therefore, if the wiring can be shortened, an effect of cost reduction can be obtained. Even if the power supply unit 400 is not disposed under the support unit 500, the same effect can be obtained as long as the power supply unit 400 is disposed in the vicinity of the support unit 500. Therefore, when the air cleaning device 200 is held at the right end of the left filter cleaning device 300 as in the present embodiment, the power supply unit 400 is disposed near the right end of the left filter cleaning device 300. Is desirable. In the present embodiment, power supply unit 400 is arranged at the center in the left-right direction of indoor unit body 110 corresponding to the vicinity of the right end of left-side filter cleaning device 300. When the air cleaning device 200 is held at the left end of the right filter cleaning device 300, it is desirable that the power supply unit 400 be disposed in the vicinity of the left end of the right filter cleaning device 300. The center in the left-right direction of the indoor unit body 110 also corresponds to the vicinity of the left end of the right filter cleaning device 300. When the air cleaning device 200 is held at the left end of the left filter cleaning device 300, it is desirable that the power supply unit 400 be disposed in the vicinity of the left end of the left filter cleaning device 300. The left end of the indoor unit main body 110 corresponds to the vicinity of the left end of the left filter cleaning device 300. When the air cleaning device 200 is held at the right end of the right filter cleaning device 300, it is desirable that the power supply unit 400 be disposed near the right end of the right filter cleaning device 300. The right end of the indoor unit main body 110 corresponds to the vicinity of the right end of the right filter cleaning device 300.

  As described above, the insertion port 311 into which both the air cleaning device 200 and the dust box 320 are inserted is provided on the front surface of the apparatus main body 310. The support unit 500 is arranged in a range from the right end of the insertion port 311 to a position advanced in the depth direction of the indoor unit main body 110. The position advanced in the depth direction of the indoor unit main body 110 is specifically a position before the lower heat exchanger 132. That is, in the present embodiment, the support portion 500 extends from the front surface of the apparatus main body 310 toward the heat exchanger 132 and is not in contact with the heat exchanger 132. For this reason, the heat exchanger 132 is not damaged by the support portion 500. Further, the support portion 500 is unlikely to hinder the air flow. Furthermore, metal parts such as terminals to be described later that protrude from the support portion 500 are difficult to cool. Metal parts such as terminals of the air cleaning device 200 that come into contact with the terminals are also difficult to cool. Moreover, the dew condensation water of the heat exchangers 131 and 132 does not flow into the support part 500. Therefore, condensation is unlikely to occur in the support unit 500 and the air cleaning device 200. In addition, the support part 500 may be arrange | positioned in the range from the left end of the insertion port 311 to the position advanced in the depth direction of the indoor unit main body 110. In that case, it is desirable to change the position of the power supply unit 400 in accordance with the position of the support unit 500. That is, it is desirable to arrange at least a part of the power supply unit 400 directly below the support unit 500.

  The support part 500 has an auxiliary receiving part 501 adjacent to the main receiving part 315. The auxiliary receiving portion 501 supports the dust box 320 together with the main receiving portion 315.

  The upper surfaces of the main receiving portion 315 and the auxiliary receiving portion 501 form a lower wall surface of the insertion port 311. The dust box 320 is supported by placing the dust box 320 on the wall surfaces, that is, the upper surfaces of the main receiving portion 315 and the auxiliary receiving portion 501. The ridge line when the upper surface of the main receiving portion 315 is viewed from the side and the ridge line when the upper surface of the auxiliary receiving portion 501 is viewed from the side have the same shape.

  In the present embodiment, the support portion 500 is manufactured as a separate element from the main receiving portion 315 and other components of the apparatus main body 310, but may be formed integrally with the main receiving portion 315. However, it may be formed integrally with other components of the apparatus main body 310.

  FIG. 11 is a view of the power supply unit 400 and the support unit 500 removed from the apparatus main body 310 of the filter cleaning apparatus 300 as viewed from the upper front side. FIG. 12 is a view showing a cross section in which the power supply unit 400 and the support unit 500 are separated and further cut along the line BB in FIG. 11. FIG. 13 is a diagram of the disassembled power supply unit 400 and the support unit 500 as viewed from obliquely above the front side. FIG. 14 is a diagram illustrating a first terminal 227, a second terminal 228, a third terminal 411 to be described later, a fourth terminal 412 to be described later, and a peripheral portion immediately before being electrically connected. In addition, in FIG. 14, the frame part 230 of the air purifying apparatus 200 is removed so that each terminal can be seen for convenience of explanation.

  The support unit 500 has an upper surface 510. The upper surface 510 is a surface on which the air cleaning device 200 is placed when the air cleaning device 200 is stored in the indoor unit main body 110. The upper surface 510 is provided with two holes, a third hole 511 and a fourth hole 512.

  The power supply unit 400 includes a fixed frame 401, a converter 403, an insulating frame 404, and a metal cover 405. A third terminal 411 and a fourth terminal 412 are attached to the power supply unit 400 via a pair of electric wires 402.

  The fixed frame 401 is a frame for fixing the power supply unit 400 to the apparatus main body 310 of the filter cleaning apparatus 300. A space for accommodating the third terminal 411 and the fourth terminal 412 is formed in the upper portion of the fixed frame 401, and the support portion 500 is fitted so as to close the space.

  The electric wires 402 electrically connect the converter 403 to the third terminal 411 and the fourth terminal 412 respectively.

  The converter 403 is attached to the fixed frame 401. The converter 403 converts electric power supplied from the outside of the indoor unit 100 of the air conditioner into desired DC power via an electric wire (not shown). In the present embodiment, converter 403 converts an AC voltage applied from a commercial power source into a DC voltage, and the obtained DC voltage is air-cleaned via electric wire 402, third terminal 411, and fourth terminal 412. Application is made to the first electrode 221 and the second electrode 222 of the apparatus 200.

  An insulating frame 404 covers the converter 403.

  The metal cover 405 is put on the insulating frame 404.

  The third terminal 411 and the fourth terminal 412 protrude from the third hole 511 and the fourth hole 512, respectively. When the air cleaning device 200 is placed on the upper surface 510 of the support portion 500, the third terminal 411 and the fourth terminal 412 are in contact with the first terminal 227 and the second terminal 228 of the air cleaning device 200, respectively. The power supply unit 400 applies different voltages to the first terminal 227 and the second terminal 228 via the third terminal 411 and the fourth terminal 412, respectively. In the present embodiment, a voltage of 6000 volts is applied to the first terminal 227 via the third terminal 411, and a voltage of 0 volts is applied to the second terminal 228 via the fourth terminal 412.

  Although the shape, size, orientation, and position of each of the third terminal 411 and the fourth terminal 412 can be changed as appropriate, in the following, the shape, size, orientation, and position employed in this embodiment are used. Will be described.

  The portion protruding from the hole of the fourth terminal 412 is desirably aligned with the portion protruding from the hole of the third terminal 411 in the left-right direction of the indoor unit body 110 with a gap. In the present embodiment, the portion protruding from the fourth hole 512 of the fourth terminal 412 is aligned with the portion protruding from the third hole 511 of the third terminal 411 in the left-right direction of the indoor unit body 110 with a gap. For this reason, when attaching the air purifying apparatus 200 to the indoor unit main body 110, the operation of bringing the first terminal 227 and the second terminal 228 into contact with the third terminal 411 and the fourth terminal 412 is simple.

  Similarly, it is desirable that the fourth hole 512 is also arranged in the left-right direction of the indoor unit body 110 with a space from the third hole 511.

  As shown in FIGS. 10 and 15, the filter cleaning device 300 includes a filter transport guide 312, a filter storage guide 313, a filter transport cover 331, and a front filter guide 332.

  The filter transport guide 312 and the filter storage guide 313 constitute the apparatus main body 310. The filter storage guide 313 and the filter transport cover 331 are installed on the filter transport guide 312. The front filter guide 332 is installed on the filter transport guide 312. The dust box 320 is also installed in the filter transport guide 312.

  The filter conveyance guide 312 includes a pair of conveyance guide side plates opposed to each other, a conveyance guide vertical beam extending on the same surface from the conveyance guide side plate, and a conveyance guide horizontal beam that connects the conveyance guide side plates and the conveyance guide vertical beams. And a conveyance guide reinforcing bar for connecting a part of the conveyance guide horizontal bars.

  A pair of transport guide side plates facing the filter transport guide 312 are provided with filter drive shafts that are rotatably supported at both ends. A drive motor that rotationally drives the filter drive shaft is installed on the side of the transport guide side plate where the filter drive shaft is not installed. And the conveyance gear 333 which meshes with the filter driven rack formed in the filter 140 is installed in the filter drive shaft.

  A conveyance guide vertical flange for forming a conveyance guide groove into which the side edge of the filter 140 can enter is installed on the mutually opposing surfaces of the conveyance guide vertical beam of the filter conveyance guide 312.

  The filter transport cover 331 is a frame body arranged in the air path. The filter transport cover 331 includes a pair of transport cover vertical beams, a transport cover horizontal beam that connects the transport cover vertical beams, and a transport cover reinforcing beam that connects the transport cover horizontal beams.

  A transport cover vertical flange for forming a transport guide groove into which the side edge of the filter 140 can enter is installed on the mutually facing surfaces of the transport cover vertical beam of the filter transport cover 331.

  The conveyance cover stringer of the filter conveyance cover 331 and the conveyance guide vertical beam of the filter conveyance guide 312 are joined. More precisely, the left conveyance cover stringer is joined to the left conveyance guide string of the left filter conveyance guide 312, and the right conveyance cover stringer is coupled to the right conveyance guide string of the right filter conveyance guide 312. To be joined. At this time, the former conveyance cover vertical flange and the latter conveyance guide vertical flange are opposed to each other with a predetermined interval, and the conveyance guide groove into which the side edge of the filter 140 can enter is formed by the interval. Since a space allowing the filter 140 to enter is also formed between the conveyance cover reinforcement beam and the conveyance guide reinforcement beam, guide means corresponding to the conveyance guide groove is formed by the conveyance cover reinforcement beam and the conveyance guide reinforcement beam. Is done.

  The filter storage guide 313 is formed on a pair of storage guide side plates facing each other, a storage guide notch portion into which the filter drive shaft enters, and a storage guide side rail that connects the storage guide side plates. And a storage guide reinforcing bar for connecting a part of the storage guide horizontal bars.

  On the mutually opposing surfaces of the storage guide side plates of the filter storage guide 313, storage guide grooves into which the side edges of the filter 140 can enter are formed. The storage guide groove has a substantially spiral shape, and is composed of a linear portion whose one end is close to the storage guide notch portion, and a substantially arc-shaped portion of approximately one and a half turns continuous to the linear portion.

  The filter 140 includes a rectangular filter ventilation body and a filter frame. The filter vent is a net-like body. On the back surface of a pair of filter vertical bars that form the outer shell of the filter 140, that is, the surface on which the filter vent is not installed, a filter driven rack that is an uneven pattern at equal intervals in the longitudinal direction, that is, the vertical direction. It is formed. In addition, this uneven | corrugated pattern is not limited to exact tooth profile shape.

  Hereinafter, an operation of moving the filter 140 will be described.

  The filter transport guide 312 is disposed near the upper surface on the front surface side of the indoor unit main body 110 and along the suction port 111 on the upper surface. The filter storage guide 313 is installed on the transport guide side plate of the filter transport guide 312. The storage guide notch of the filter storage guide 313 is closer to the front surface, and the storage guide groove is behind it, that is, closer to the heat exchanger 131. To position. Further, a filter transport cover 331 is installed on the transport guide vertical rail of the filter transport guide 312.

  Therefore, the side edge of the filter 140 is in a state where it has entered the conveyance guide groove, which is a gap between the conveyance guide vertical flange of the filter conveyance guide 312 and the conveyance cover vertical flange of the filter conveyance cover 331, and almost the entire range of the filter 140 is wound. It is returned and expanded. At this time, the tip, which is one end of the filter 140, exhibits a substantially circular arc with a small curvature radius when viewed from the side in a state sandwiched between the upper surface of the dust box 320 and the transport gear 333.

  When the transport gear 333 rotates in the forward direction, both side edges of the filter 140 are sent out toward the storage guide groove. The tip of the filter 140 is initially guided by the linear portion of the storage guide groove and moves in a substantially linear shape. However, when the filter 140 reaches the substantially arc-shaped portion of the storage guide groove, it moves in a spiral shape. When the rear end portion, which is the other end portion of the filter 140, approaches the transport gear 333, most of the filter 140 is wound in a substantially spiral shape of about one and a half turns. During this movement, the filter ventilation body of the filter 140 hits the surface on the windward side of the air passage with the dust removal brush of the dust box 320, and dust removal is executed.

  On the other hand, when the transport gear 333 rotates in the reverse direction, the filter 140 is rewound and both side edges of the filter 140 are sent out to the transport guide groove. When the filter 140 covers the entire area of the air path, the rotation of the transport gear 333 stops. At this time, a part of the filter driven rack of the filter 140 meshes with the transport gear 333.

  As described above, the apparatus main body 310 movably houses the filter 140 that captures dust in the air, but the filter 140 not only moves inside the filter cleaning apparatus 300 but also outside the filter cleaning apparatus 300. It can also be taken out.

  As shown in FIGS. 9 and 10, the front filter guide 332 is attached to the front surface of the apparatus main body 310 so as to be freely opened and closed.

  An opening for taking out the filter 140 is formed on the front surface of the filter transport guide 312. The front filter guide 332 covers the opening and guides the movement of the filter 140 in the closed state.

  A rotation axis of the front filter guide 332 for opening and closing the front filter guide 332 is formed at a position below the opening of the filter transport guide 312. On the other hand, at a position above the opening of the filter transport cover 331, a fixing portion 314 is provided for fixing an end portion on the side far from the rotation center of the front filter guide 332 when the front filter guide 332 is closed. Therefore, in the closed state of the front filter guide 332, not only the end near the rotation center of the front filter guide 332 but also the end far from the rotation center of the front filter guide 332 is fixed to the apparatus main body 310. For this reason, according to this Embodiment, the front filter guide 332 can be fixed reliably.

  The front filter guide 332 hangs down by its own weight in the open state. Therefore, according to the present embodiment, it is not necessary for the user of the air conditioner to support the front filter guide 332 by hand in order to keep the front filter guide 332 open, and the front filter guide 332 is provided by some fixing mechanism. There is no need to be fixed.

  The front filter guide 332 is a movable member located between the front panel 150 attached to the indoor unit main body 110 and the filter 140. The front filter guide 332 is provided with a guide portion that is in contact with the filter 140 when moving, and serves as a conveyance path for the filter 140. The front filter guide 332 can be opened so that the user of the air conditioner can easily remove the filter 140.

  The front filter guide 332 and the dust box 320 are not integrated, and are formed separately. In the space created after the dust box 320 is removed, that is, the space where the dust box 320 was originally installed, the front filter guide 332 after the rotational movement is disposed. By providing the front filter guide 332 separately above the dust box 320, both can be efficiently stored. Further, when the front filter guide 332 rotates, a rotation locus can be ensured without interfering with other members.

  Thus, in the present embodiment, the dust box 320 for storing the dust captured by the filter 140 is detachably attached to the front surface of the filter transport guide 312 separately from the front filter guide 332. For this reason, the user of the air conditioner need only remove the dust box 320 when discarding the dust accumulated in the dust box 320 and does not need to remove the front filter guide 332. It is desirable that the front filter guide 332 is not easily removed.

  In the present embodiment, the front filter guide 332 is hung down to expose the filter 140, so that the filter 140 can be easily taken out with both hands without requiring a special fixing mechanism.

  FIG. 16 is a view of the dust box 320 as viewed from the upper front side. FIG. 17 is a view of the dust box 320 as seen from diagonally below the front side. FIG. 18 is a view of the dust box 320 as viewed from obliquely above on the back side. 19, 20, 21, and 22 are views showing different cross sections of the dust box 320. FIG. 23 is a diagram showing only the lower part of the dust box 320 by cutting the dust box 320 for the sake of explanation.

  The dust box 320 includes a wall plate 321 combined in a box shape, a dust removing shaft 322 supported on both side wall plates 321 so as to be swingable at both ends, and a stopper member 323 attached to the front wall plate 321. .

  The wall plate 321 forms a dust collection chamber 324 that is a space for storing dust. A dust removal brush (not shown) is attached to the dust removal shaft 322. The upper wall plate 321 has a center opening in the width direction when viewed from above, and a brush hole 341 through which the tip of the dust removing brush passes is formed substantially at the center when viewed from the side. When the dust box 320 is attached to the filter transport guide 312 and the dust removing shaft 322 swings, the dust removing brush also swings. Therefore, the dust adhering to the filter 140 is scraped off by swinging the dust removing brush while the filter 140 is in contact with the dust removing brush. The dust that is scraped off falls into the dust collection chamber 324 and is stored. At this time, since the filter 140 moves, a wide range of the filter 140 can be removed.

  The rear wall plate 321 is inclined at a lower portion to form a slope portion 342. The inclined surface 342 and the lower wall plate 321 form a lid 343 of the dust collection chamber 324.

  When attached to the filter transport guide 312, the dust box 320 is fixed so that it cannot be pulled out by the spring force of the stopper member 323. The user of the air conditioner can remove the dust box 320 by sliding the stopper member 323. Then, by opening the lid 343, the dust accumulated in the dust collecting chamber 324 can be discarded.

  In the present embodiment, in order to securely fix the front filter guide 332 and to reliably transport the filter 140, the front filter guide 332 and the dust box 320 are separated from each other, and are in contact with the front filter guide 332. Fixing portions 344 and 345 for pressing and fixing the front filter guide 332 are provided in the dust box 320.

  When attaching the dust box 320, the dust box 320 is attached later with the front filter guide 332 fixed to the apparatus main body 310. In order to increase the space efficiency, the front filter guide 332 is rotated only when the dust box 320 is removed because the rotation path of the front filter guide 332 uses the space in which the dust box 320 is mounted. In addition, the dust box 320 can be mounted only after the front filter guide 332 is moved back to the original mounting position. Therefore, the front filter guide 332 is closed and the dust box 320 is attached later, so that the fixing by the fixing portions 344 and 345 can be performed.

  The front filter guide 332 is pressed from the front to the rear by the fixing portion 344 provided in the dust box 320. The fixing portion 344 is on the side facing the front filter guide 332 on the back side of the dust box 320. A protrusion 346 is provided at the top of the dust box 320. The fixing portion 344 may be the back surface of the protruding portion 346 itself, but in the present embodiment, the fixing portion 344 is a rib provided on the back surface of the protruding portion 346 and contacts the front filter guide 332 so that the front filter guide 332 is attached. Press and fix. Therefore, by attaching the dust box 320, the front filter guide 332 can be fixed by bringing the fixing portion 344 into contact with the front filter guide 332 from the front and applying a force to the rear.

  The front filter guide 332 is fixed over the width direction by fixing the front filter guide 332 with the fixing portion 344 provided on the protruding portion 346 protruding above the dust box 320. Therefore, only the both sides of the front filter guide 332 are fixed, and the fixing of the center portion is loosened, and only the center does not move slightly back and forth. For this reason, the meshing between the filter 140 and the transport gear 333 is loosened, and the problem that the filter 140 is detached from the transport gear 333 is eliminated.

  Both sides of the dust box 320 are fixed to the filter transport guide 312. In this state, the facing portion 347 excluding the protruding portion 346 on the top surface portion of the dust box 320 enters the lower side of the front filter guide 332 and faces the front filter guide 332. The angle between the facing portion 347 and the protruding portion 346 is about 90 degrees. That is, the facing portion 347 and the protruding portion 346 are formed in an L shape in a side view, and the former contacts the front filter guide 332 from below and the latter contacts the front filter guide 332 from the front.

  With such a configuration, the front filter guide 332 and the dust box 320 can be arranged with small required dimensions. When the facing portion 347 of the dust box 320 enters below the front filter guide 332, the vertical dimension can be reduced. The opposing portion 347 of the dust box 320 and the protruding portion 346 form an angle of approximately 90 degrees, and the protruding portion 346 presses the front filter guide 332 from the front to the rear, thereby reducing the size in the front-rear direction.

  Since the front filter guide 332 can be pressed and fixed by the fixing portion 344 so that the front filter guide 332 does not move back and forth, the filter 140 is not detached from the transport gear 333 and is integrally formed in the dust box 320. It is possible to obtain a filter cleaning device 300 that reliably conveys the filter 140 at a low cost without increasing the number of parts by eliminating the need for a new pressing member other than the protruding portion 346.

  The front filter guide 332 is pressed upward from below by a fixing portion 345 provided in the dust box 320. The fixing portion 345 is on the side facing the front filter guide 332 on the upper surface side of the dust box 320. The fixing portion 345 may be the surface itself of the facing portion 347 of the dust box 320, but in the present embodiment, the fixing portion 345 is a rib provided on the surface of the facing portion 347, and comes into contact with the front filter guide 332 to contact the front filter. The guide 332 is pressed and fixed. Therefore, the front filter guide 332 can be fixed by attaching the dust box 320 and bringing the fixing portion 345 into contact with the front filter guide 332 from below and applying a force upward.

  The front filter guide 332 is fixed over the width direction by fixing the front filter guide 332 with the fixing portion 345 provided in the facing portion 347 of the top surface portion of the dust box 320. Therefore, only the both sides of the front filter guide 332 are fixed, and the fixing of the center portion is loosened, and only the center does not move slightly back and forth. For this reason, the meshing between the filter 140 and the transport gear 333 is loosened, and the problem that the filter 140 is detached from the transport gear 333 is eliminated.

  Since the front filter guide 332 can be pressed and fixed by the fixing portion 345 so that the front filter guide 332 does not move back and forth, the filter 140 is not detached from the transport gear 333, and a new pressing member is unnecessary. Thus, it is possible to obtain the filter cleaning device 300 that reliably conveys the filter 140 inexpensively without increasing the number of parts.

  In addition, if either one of the fixing portions 344 and 345 is provided, the above-described effect can be obtained, but in order to obtain a greater effect, both the fixing portions 344 and 345 may be provided. desirable.

  Although not shown, as another means for pushing the front filter guide 332 from the front, a push rib protruding from the back surface of the front panel 150 attached to the indoor unit main body 110 to a portion facing the front filter guide 332 is formed. Then, the front filter guide 332 may be pressed from the front to the rear by the push rib. Also in this case, it is possible to obtain the filter cleaning device 300 that reliably conveys the filter 140 at a low cost without increasing the number of components without requiring a new pressing member.

  A lifting rib 348 for lifting the dust box 320 protrudes from the bottom surface of the dust box 320. The presence of the lifting rib 348 can prevent the dust box 320 from being tilted back and forth due to dimensional variations. That is, when the dust box 320 is tilted forward, it is difficult to apply a force to the rear by the fixing portion 344. Therefore, such a situation can be prevented by providing the lifting rib 348. In addition, the dust box 320 can be easily mounted when the dust box 320 is attached by applying only the lifting rib 348 instead of hitting the entire lower surface of the dust box 320 to the frame of the filter transport guide 312.

  The lifting rib 348 is preferably spherical. By making the lifting ribs 348 spherical, the lifting ribs 348 can be prevented from being caught by the frame of the filter transport guide 312 when the dust box 320 is attached. Therefore, the mounting becomes smooth. Further, it is desirable that at least two lifting ribs 348 are provided on both sides of the dust box 320 in the width direction. By doing so, the dust box 320 does not tilt up and down, and the dust box 320 does not tilt forward and backward in the entire width direction. Therefore, the front filter guide 332 can be reliably pressed and fixed from the front to the rear by the fixing portion 344.

  As described above, in the present embodiment, the dust box 320 presses the front filter guide 332 to fix the front filter guide 332 to the attachment position of the front filter guide 332 in the apparatus main body 310. For this reason, according to this Embodiment, the front filter guide 332 can be fixed reliably.

  The dust box 320 presses the front filter guide 332 at least rearward to fix the front filter guide 332 at the mounting position. Specifically, the dust box 320 is provided with a facing portion 347 that faces the front filter guide 332 and a protruding portion 346 that protrudes in a plate shape from a position before the facing portion 347 on the upper surface. The dust box 320 presses the front filter guide 332 backward by one of both surfaces of the protrusion 346 in the thickness direction.

  The dust box 320 presses the front filter guide 332 at least upward to fix the front filter guide 332 at the mounting position. Specifically, the dust box 320 presses the front filter guide 332 upward by the surface of the facing portion 347.

  The dust box 320 is provided with a lifting rib 348 that presses the filter transport guide 312 on the lower surface. The lifting rib 348 is preferably hemispherical. In addition, it is desirable that a plurality of lifting ribs 348 are arranged along the left-right direction of the dust box 320.

  In the present embodiment, the dust box 320 has a box shape with a substantially trapezoidal cross section. The upper and lower sides of the trapezoid are parallel and the upper side is longer than the lower side. The dust box 320 is installed between the front panel 150 and the heat exchangers 131 and 132 in the front-rear direction. The front part of the dust box 320 is substantially flat and is exposed to the user of the air conditioner when the front panel 150 is opened. The lower surface portion of the dust box 320 is substantially flat and is installed on the frame of the filter transport guide 312. The back surface portion of the dust box 320 is inclined obliquely from the lower side to the upper side toward the rear side. The back part of the dust box 320 is opposed to the heat exchangers 131 and 132 provided at the rear, and is exposed.

  A part of the air cleaning device 200 can be accommodated in a space created at the rear of the lower side because the rear surface of the dust box 320 is inclined obliquely from the lower side to the upper side. Therefore, the depth dimension of the indoor unit 100 of the air conditioner can be reduced.

  In the present embodiment, a part of the filter transport guide 312 forms the support portion 500. The support unit 500 detachably holds the air cleaning device 200 that cleans the air that has passed through the filter 140.

  The air cleaning device 200 is installed in front of the heat exchangers 131 and 132 further behind the dust box 320 behind the front panel 150. The user of the air conditioner can take out the air cleaning device 200 and perform maintenance such as cleaning. The user of the air conditioner can easily take out the air cleaning device 200 by grasping the handle 233 of the air cleaning device 200 by hand.

  The air cleaning device 200 is disposed below the filter storage guide 313 and between the dust box 320 and the heat exchangers 131 and 132. In this way, it is easy to pass the wind coming from above, and the dead space between the dust box 320 and the heat exchangers 131 and 132 below the filter storage guide 313 is effectively used to make the air conditioner The depth dimension and height dimension of the indoor unit 100 can be reduced.

  As shown in FIGS. 2 and 6, a part of the handle 233 of the air cleaning device 200 is inclined obliquely downward from the rear to the front. It is desirable to incline the inclined portion and the inclined portion 342 of the dust box 320 at substantially the same angle. The substantially equal angle is an angle whose difference is within 30 degrees.

  When the user of the air conditioner tries to install the air purifier 200 after maintenance, the user of the air conditioner inserts the air purifier 200 only halfway or only places the air purifier 200. There is a risk of stagnation. In that case, quality deterioration such as poor connection due to the lack of electrical contact of the air cleaning device 200 or generation of abnormal noise due to air discharge will be caused.

  Therefore, in the present embodiment, the back surface portion including the inclined surface portion 342 of the dust box 320 contacts the handle 233 of the air cleaning device 200 even if the air cleaning device 200 is not correctly mounted. By doing in this way, only the operation | movement which attaches the dust box 320 by the user of an air conditioner, and the back part of the dust box 320 hits the handle 233 irrespective of the intention of the user of an air conditioner, an air purifier 200 is forced backwards and downwards. Therefore, the air cleaning device 200 is automatically attached to the support portion 500 formed in the filter transport guide 312.

  When the ratio of the length of the inclined surface portion 342 to the entire length of the back surface portion is more than half of the back surface portion of the dust box 320, the area hitting the handle 233 of the air cleaning device 200 increases, and the handle 233 of the air cleaning device 200 is removed. While sliding downward, or sliding the handle 233 of the air cleaning device 200 downward, it can be reliably guided downward.

  The back surface portion of the dust box 320 includes two or more surfaces of a slope portion 342 and a portion extending in the vertical direction other than the slope portion 342, so that the dust removal brush can be easily installed in the dust collection chamber 324. That is, the volume of the dust collection chamber 324 can be increased when the back surface portion of the dust box 320 is formed with two or more surfaces as compared with the case where the back surface portion of the dust box 320 is formed with only one surface of the slope portion 342.

  If the height of the slope portion 342 on the back surface of the dust box 320 is higher than the height of the portion other than the slope portion 342 on the back surface portion, the area corresponding to the extending portion 52 becomes large. Therefore, it is possible to reliably guide the air purifier 200 downward while sliding the handle 233 of the air purifier 200 or sliding the handle 233 of the air purifier 200 downward.

  In the present embodiment, the dust box 320 presses the air cleaning device 200 and fixes the air cleaning device 200 to the holding position of the air cleaning device 200 in the filter transport guide 312. That is, the dust box 320 presses the air cleaning device 200 and fixes the air cleaning device 200 to the support portion 500. For this reason, according to this Embodiment, it becomes easy to attach the air purifying apparatus 200 to the correct position of the filter cleaning apparatus 300. FIG.

  At least a part of the back surface of the dust box 320 is inclined obliquely downward, and the air cleaning device 200 is pressed by the inclined surface portion 342 that is the inclined portion. For example, the dust box 320 presses the handle 233 provided at the lower part of the front surface of the air cleaning device 200 backward and downward by the inclined surface portion 342.

  As the surface area of the slope portion 342 increases, the dust box 320 can reliably press the air cleaning device 200 to the correct position by the slope portion 342. Therefore, in the dust box 320, it is desirable that the back-and-forth dimension of the slope portion 342 on the back surface is larger than the back-and-forth dimension of other portions on the back surface. Further, in the dust box 320, it is desirable that the vertical dimension of the slope 342 on the back surface is larger than the vertical dimension of other portions on the back surface.

  Although the entire back surface of the dust box 320 may be the slope portion 342, in this case, the volume of the dust collection chamber 324 is reduced. Therefore, it is desirable that the dust box 320 has a portion extending perpendicularly to a part of the back surface. In other words, it is desirable that the dust box 320 has a portion excluding the inclined portion 342 on the back surface extending vertically.

  In the present embodiment, as described above, since the inclined surface 342 is provided on the back surface of the dust box 320, the dust box 320 is filtered in a state where the air cleaning device 200 is in front of the holding position of the air cleaning device 200 in the filter transport guide 312. When attached to the front surface of the conveyance guide 312, the air cleaning device 200 is pushed into the correct holding position by the dust box 320 and fixed.
