  In a situation where communication with the neighborhood is estranged like in recent years, it is often the case that you do not notice that your actions are unpleasant to others where you do not notice, and if you spend it as it is, the same because you do not notice Due to repeated actions, unexpected troubles may occur. To avoid this, there are many people who act as good neighbors even when communication is estranged and try to avoid problems with their neighbors as much as possible. For these people, it is necessary to consider the direction of the exhaust air accompanying the ventilation of the room, and there is a demand for a product that is attentive so that the exhaust air from the home does not become uncomfortable to other homes.

  In addition, there are not a few people who react excessively to allergens in the outside air, and if the room where these people are located is exhausted and ventilated, the exhausted amount of outside air will flow from the gaps in the building and the room will be contaminated with allergens. . For this reason, it is necessary to take a method in which ventilation is performed by inhalation and allergen substances are captured in the course of the inhalation path.

  In Patent Document 1, there is no mention of cleaning of intake air, and there is no mention of dust removed from the circulating airflow filter.

  In patent documents 2-5, since the collected dust is discharged outside the room, consideration for a person who wishes a good neighbor is insufficient. In addition, there is no mention of exhausting allergens such as pollen contained in the outside air from the gaps in the house.

  Therefore, it is desirable to perform filter maintenance simply without causing any inconvenience in the vicinity, and to perform air conditioning that does not contaminate the room with outside air.

  An object of the present invention is to provide a dust collection box that collects dust from a circulating airflow filter and an air conditioner that can easily clean an outside air filter for intake air. It is another object of the present invention to provide an air conditioner that does not pollute the room with outside air.

  An object of the present invention is to provide a cleaning mechanism for a circulating airflow filter, a storage unit for dust removed by the cleaning mechanism, a mechanism for introducing outside air into a room, an outside air filter attached to the introduction mechanism, and an outside air filter. In an air conditioner having a storage unit, the storage unit and the storage unit are provided adjacent to each other.

An object of the present invention is an air conditioner including a cleaning mechanism for a circulating airflow filter and an air supply mechanism for supplying outside air into the room,
Equipped with a dust collection box,
In this dust collection box, a storage unit that stores dust cleaned by the cleaning mechanism and a storage unit that stores an outside air filter that removes dust from outside air supplied by the air supply mechanism are integrally configured. Is achieved.

  According to the present invention, maintenance of a dust collection box that collects dust from a circulating airflow filter and an outside air filter for intake air can be easily performed. Furthermore, an air conditioner that does not pollute the room with outside air can be provided. Further, there is no waste in the arrangement, and space saving can be achieved. In addition, convenience for the user is improved.

  Hereinafter, an embodiment of an air conditioner of the present invention will be described with reference to the drawings. First, the whole structure of an air conditioner is demonstrated using FIGS. 1-3. FIG. 1 is a configuration diagram of an air conditioner. FIG. 2 is an internal front view of the indoor unit of FIG. FIG. 3 is a side sectional view of the indoor unit of FIG.

  In FIG. 1, an air conditioner generally indicated by reference numeral 1 connects an indoor unit 2 and an outdoor unit 6 with a refrigerant pipe 8 to air-condition the room. In the indoor unit 2, a heat exchanger 33 is placed at the center of the housing 21, and a cross-flow fan type blower fan 311 having a length substantially equal to the width of the heat exchanger 33 is disposed below the heat exchanger 33, 35, etc. are attached, covered with a decorative frame 23, and a front panel 25 is attached to the front surface of the decorative frame 23.

  The decorative frame 23 is provided with an air inlet 27 for sucking in indoor air and an air outlet 29 for blowing air in which temperature and humidity are harmonized, and the length of the blower fan 311 is the length of the blown airflow from the blower fan 311. The left and right wind direction plates 295 arranged in the middle of the blow air path 290 deflect the left and right directions of the air flow, and the upper and lower air direction plates 291 attached to the blow outlet 29 The direction is deflected and blown into the room. In addition, a display unit 397 for displaying an operation state and a light receiving unit 396 for receiving an infrared operation signal from a separate remote controller 5 are arranged on the side portion of the vertical wind direction plate 291.

Basic internal structures such as a blower fan 311, a circulating airflow filter 231, a heat exchanger 33, a dew tray 35, an up / down wind direction plate 291 and a left / right wind direction plate 295 are attached to the housing 21. And basic internal structures, such as the ventilation fan 311 attached inside the housing | casing 21, are included in the indoor unit 2 by attaching the decorative frame 23. FIG.

  An air outlet 29 formed on the lower surface of the decorative frame 23 is disposed adjacent to the divided portion with the front panel 25 and communicates with the rear outlet air passage 290. The two up-and-down airflow direction plates 291 substantially conceal the blowing air passage 290 in the closed state, and form a continuous large curved surface on the bottom surface of the indoor unit 2. The vertical wind direction plate 291 is pivoted at a required angle during operation of the air conditioner by a drive motor (not shown) in response to an instruction from the remote controller 5 with pivot shafts provided at both ends as fulcrums. Open the mouth 29 and hold the state. When the operation of the air conditioner is stopped, the air outlet 29 is controlled to be closed.

  The left and right wind direction plates 295 are configured to be rotatable by a drive motor (not shown) with a rotation shaft provided at the lower end as a fulcrum, and are rotated in accordance with an instruction from the remote controller 5 to maintain the state. Blowing air is blown out in the desired direction on the left and right. By instructing from the remote controller 5, the up and down wind direction plate 291 and the left and right wind direction plate 295 can be periodically oscillated during the operation of the air conditioner, and the blown air can be periodically sent over a wide range in the room.

  Further, the movable panel 251 on the front surface is configured to be rotatable about a rotation shaft provided at the lower portion by rotating a drive motor (not shown), and opens the front air suction portion 230 ′ during the operation of the air conditioner. Indoor air is sucked into the indoor unit 2 not only from the circulating airflow filter 231 but also from the front air suction portion 230 ′. When the air conditioner is stopped, the front air suction portion 230 'is controlled to be closed.

  And according to the indoor unit 2 of a present Example, at the time of a stop, the air blowing wind path 290 and the front side air suction part 230 'are concealed with the up-and-down wind direction board 291 and the movable panel 251, and are matched with interior. During operation, the up / down wind direction plate 291 and the left / right wind direction plate 295 are rotated in accordance with an instruction from the remote controller 5. At the same time, the movable panel 251 is opened to suck room air from the front air suction part 230 ′ and the upper air suction part 230. The sucked indoor air can be blown out from the air outlet 29 by being cooled or warmed by the internal heat exchanger 33.

  When the air conditioner 1 is operated, it is connected to a power source (not shown) and the remote controller 5 is operated to perform desired operations such as cooling, dehumidification, and heating. In the case of operation such as cooling, in order to pass room air through the heat exchanger 33 in the front part of the blower fan 311, the movable panel 251 constituting a part of the front panel 25 is rotated and opened as shown in FIG. The room air is circulated to the heat exchanger 33 through the upper air suction portion 230 and the front air suction portion 230 ′ of the decorative frame 23 behind the opened movable panel 251.

  The indoor unit 2 includes a control board in an electrical component box (not shown) inside, and a microcomputer is provided on the control board. The microcomputer receives signals from various sensors such as an indoor temperature sensor and an indoor humidity sensor (not shown), receives an operation signal from the remote controller 5 at the light receiving unit 396, an indoor blower fan 311, a movable panel drive motor, an up / down wind direction plate. The indoor unit 2 is controlled in an integrated manner, such as controlling the drive motor, the left and right wind direction plate drive motors, and controlling the communication with the outdoor unit.

  The indoor unit 2 is in a state where the operation is stopped, and the movable panel 251 and the up-and-down airflow direction plate 291 are closed as shown by a one-dot chain line in FIG. In this state, when a driving operation signal is transmitted from the remote controller 5, the microcomputer (not shown) performs cooling or heating based on the operation signal from the remote controller 5 or information from various sensors if automatic operation is set. Determine the operation mode. Based on this determination, the movable panel 251 and the up / down wind direction plate 291 are operated to open the airflow passage. At this time, the air suction part 230 'is opened, but the line of sight from the room is blocked by the movable panel 251 and does not reach the interior of the indoor unit 2, so that the interior of the room is not damaged.

  That is, the microcomputer operates a drive motor (not shown) to rotate the up / down wind direction plate 291 and the left / right wind direction plate 295 to the blowing angle corresponding to the instruction from the remote controller 5. Further, the microcomputer operates a movable panel drive motor that opens the movable panel 251 in conjunction with the operation of the up / down wind direction plate 291.

  Next, the microcomputer rotates the indoor fan 311 and sucks indoor air from the upper and front air suction portions 230 and 230 ′. Control is performed so that the sucked room air is blown out from the air blowing port 29 along the up-and-down air direction plate 291 and the left-and-right air direction plate 295 without performing heat exchange with the heat exchanger 33. On the other hand, when stopping the operation, the indoor blower fan 311 is stopped, and the drive motor of the movable panel 251 and the drive motor of the up-and-down air direction plate 291 are reversely rotated. In this way, control is performed to return from the open state to the closed state.

  The circulating airflow filter 231 is disposed so as to cover the suction side of the heat exchanger 33 and removes dust contained in the sucked indoor air. The blower fan 311 is a horizontally long cross-flow fan, and is arranged at the center in the indoor unit 2 so as to suck indoor air from the air suction port 27 and blow it out from the air blowout port 29. The heat exchanger 33 is disposed on the suction side of the blower fan 311 and has a substantially inverted V shape.

  The dew tray 35 is disposed below the lower ends of the front and rear sides of the heat exchanger 33 and is provided to receive condensed water generated in the heat exchanger 33 during cooling operation or dehumidifying operation. The condensed water received and collected is discharged to the outside through the drain pipe 37. As a result, a main air passage is formed to flow indoor air to be conditioned. That is, by operating the blower fan 311, the indoor air is sucked from the air suction port 27, heat exchanged by the heat exchanger 33 through the circulation airflow filter 231, and then blown into the room from the air outlet 29. The

  Next, the cleaning means for the circulating airflow filter will be described with reference to FIG. FIG. 4 is a perspective view of the cleaning mechanism.

  In the embodiment, planar circulation airflow filters 231 and 231 ′ are provided on two substantially perpendicular surfaces facing the upper air suction portion 230 and the front air suction portion 230 ′ upstream of the heat exchanger 33. The circulating airflow filters 231 and 231 ′ are engaged with the guide frame 234. The guide frame 234 has rails 235 and 235 ′ on the upper rear part and the front lower part, and a propulsion shaft 243 at the intersection where the circulation airflow filters 231 and 231 ′ are extended. Prepare.

  Here, when there are parts having the same function for the upper circulation airflow filter 231 and the front circulation airflow filter 231 ′, the part for the upper circulation airflow filter 231 is added to the part for the front circulation airflow filter 231 ′. Add “′” to to distinguish.

  The propulsion shaft 243 has a polygonal cross section, is supported by a bearing 245 provided on the guide frame 234, and is fixed to the guide frame 234 via a gear attached to one end passing through the bearing 245 on one side. Connected to A screw 244 and a carriage 261 are loosely mounted on the propulsion shaft 243, and the screw 244 meshes with a rack 237 provided on the guide frame 234 and parallel to the propulsion shaft 243.

  Brush support frames 262 and 262 'are suspended between the carriage 261 and the rails 235 and 235' across the circulating airflow filters 231 and 231 ', respectively, and the circulating airflow filters 231 and 231 are mounted on the brush support frames 262 and 262'. Cleaning brushes 267 and 267 'for sweeping and cleaning' are attached.

  Thus, by rotating the moving motor 242, the propulsion shaft 243 and the screw 244 rotate, and the screw 244 moves in the left-right direction along the rack 237 according to the rotating direction of the moving motor 242, thereby moving the carriage 261. Move. As a result, the cleaning brushes 267 and 267 ′ move so as to sweep while being in sliding contact with the circulating airflow filters 231 and 231 ′, and dust on the circulating airflow filters 231 and 231 ′ is swept away by the cleaning brushes 267 and 267 ′. The removal brushes 271 and 271 ′ on the left side of the guide frame 234 are moved.

  As the bristles of the cleaning brushes 267 and 267 ′, for example, soft bristles with a hardness of 50 or less as defined in JIS S3016 are used, and the cleaning brushes 267 and 267 ′ are pressed against the circulating air flow filters 231 and 231 ′ and moved. When the circulating airflow filters 231 and 231 ′ are deformed by the pressing of the cleaning brushes 267 and 267 ′, it is necessary to select them in accordance with the rigidity of the circulating airflow filters 231 and 231 ′ so that an allowance of 2 mm or more can be secured. good. Here, the overlap margin means the circulation corresponding to the length from the position of the circulating air flow filter surface to the deformed hair tip when it is assumed that the hairs of the cleaning brushes 267 and 267 'are straight without deformation. The distance between two points up to the position of the airflow filter surface.

  As described above, since soft hair is used for the cleaning brushes 267 and 267 ', the force for deforming the circulating airflow filters 231 and 231' is small, and it is only necessary to sweep the circulating airflow filters 231 and 231 'from one side. Dust on the circulating airflow filters 231 and 231 'can be swept away without supporting 231 and 231' from the back side. For this reason, the drive mechanism for sweeping the circulating air flow filters 231 and 231 'with the cleaning brushes 267 and 267' only needs to be provided only on one side of the circulating air flow filters 231 and 231 ', so the driving mechanism is greatly simplified. Is done.

  Next, the configuration and operation of the cleaning mechanism will be described using the upper cleaning mechanism as an example with reference to FIG. FIG. 5 is an explanatory view showing the operation of sweeping collected dust.

On the right side of the circulating airflow filter 231 is a standby unit 238 on which the cleaning brush 267 waits when the cleaning operation is not performed. As shown in FIG. 5D, when the cleaning operation is performed, the drive mechanism of the cleaning brush 267 waiting in the standby portion 238 as shown in FIG. 5F is operated to sweep the circulating air flow filter 231. Move. At this time, the bristles of the cleaning brush 267 run from the open state of the recess F234f onto the surface of the circulating airflow filter 231 protruding through the slope F233f while gradually bending and deforming the hair tips and firmly sliding with the circulating airflow filter 231. Touch.

  The cleaning brush 267 sweeps the circulating air filter 231 while moving in the direction of the removal brush 271 and sweeps the dust 236. The cleaning brush 267 that has finished sweeping the circulating airflow filter 231 passes through the portion C in FIG. 5 together with the dust 236 that has been swept away, reaches the removal brush 271, and effectively contacts the removal brush surface 271 a while sliding the dust 236. Transfer to the removal brush 271.

  Next, operations of the removal brushes 271 and 271 ′ and the dust return prevention brushes 273 and 273 ′ will be described with reference to FIGS. 6 to 9 by taking the upper removal brush 271 and the dust return prevention brush 273 as an example. 6 to 9, the operation explanatory diagrams of FIGS. 6 (a), 6 (b), 7 (c), 7 (d), 8 (e), 8 (f), Drawing numbers (a) to (h) are given in order of operation as shown in FIGS. 9 (g) and 9 (h).

  The removal brush 271 is provided on the side of the circulating airflow filter 231 and is pivotally supported by the brush holder 276 to form a semi-cylindrical shape as shown in FIG. About half of the semi-cylindrical surface constitutes a brush surface 271a that is inclined and planted, and the other semi-cylindrical surface is a non-brush surface 271b. The direction of the inclined flocking is perpendicular to the axis of the semi-cylinder and is in the direction of the circulating air filter 231. As the brush support frame 262 moves, the circulating brush 267 slidably contacts the circulating air filter 231 and collects the circulation. Dust on the airflow filter 231 is rubbed against the brush surface 271a as shown in FIG.

  Since the moving direction of the cleaning brush 267 and the direction of the inclined flocking of the brush surface 271a are opposite to each other, the brush surface 271a scrapes off dust carried by the cleaning brush 267 and holds it on the brush surface 271a. Reference numeral 268 denotes a brush presser for suppressing excessive deformation of the cleaning brush 267 and not deteriorating the function of cleaning the circulating air flow filter 231 of the cleaning brush 267.

  When the brush support frame 262 further moves to the left, the lever protrusion 269 of the brush support frame 262 pushes the rotation lever 271c attached coaxially with the removal brush 271 as shown in FIG. 7C, and the rotation lever 271c is moved to the left. Push towards. The rotation lever 271c is attached to the removal brush 271 via a rotation spring 271d, and the rotation spring 271d biases the rotation lever 271c in the clockwise direction.

  The rotating lever 271c is pushed by the lever protrusion 269 and rotates counterclockwise as shown in FIG. 7 (d). Finally, the lever protrusion 269 gets over the rotating lever 271c, as shown in FIG. 8 (e). As described above, the rotation lever 271c rotates backward in the clockwise direction by the urging force of the rotation spring 271d and returns to the position of the stopper 271f, and is in the same position as in FIG.

  The brush support frame 262 stops when the lever protrusion 269 gets over the rotation lever 271c, reverses and starts moving in the direction of the circulating air flow filter 231. Reference numeral 271e denotes a fin attached to the removal brush 271 and sweeps away dust in a portion near the base of the cleaning brush 267 that did not slide on the brush surface 271a.

  Next, the operation after the movement direction of the brush support frame 262 is reversed will be described with reference to FIGS.

  As shown in FIG. 8F, the brush support frame 262 that is reversed and moved in the direction of the circulating airflow filter 231 pushes the rotating lever 271c to the right by the lever projection 269, and rotates the rotating lever 271c in the clockwise direction. Let The rotation lever 271c pushes the removal brush 271 clockwise through the stopper 271f of the removal brush 271, and the removal brush 271 rotates against the counterclockwise urging force of the return spring 277.

  As the removal brush 271 rotates, the removal brush surface 271a sinks into the brush holder 276 while slidingly contacting the dust return prevention brush surface 273a of the dust return prevention brush 273. At this time, since the dust return preventing brush surface 273a is pressed against the removal brush surface 271a by the pressing spring 278, the sliding contact state between the removal brush surface 271a and the dust return preventing brush surface 273a is maintained. The dust return prevention brush surface 273a of the dust return prevention brush 273 is provided with inclined flocking in the same direction as the inclined flocking direction of the removal brush surface 271a at a position in sliding contact with the removal brush surface 271a. For this reason, when the removal brush surface 271a enters the inside of the brush holder 276, the dust 236 held on the removal brush surface 271a also enters the inside of the brush holder 276 without being obstructed by the inclined flocking of the dust return prevention brush surface 273a. .

  The rotation lever 271c is pushed by the lever protrusion 269 and rotates clockwise as shown in FIG. 9G. Finally, the lever protrusion 269 gets over the rotation lever 271c. When the lever protrusion 269 climbs over the rotation lever 271c, the rotation lever 271c rotates counterclockwise by the biasing force of the return spring 277 as shown in FIG. 9 (h), and the fin 271e opens the opening edge of the brush holder 276. In this case, the opening edge serves as a stopper and becomes the same state as in FIG. Thereafter, as shown in FIG. 6A, the cleaning brush 267 stands by in preparation for carrying the dust 236 of the circulating airflow filter 231.

  When the removal brush 271 rotates counterclockwise, the direction of the inclined flocking of the dust return prevention brush surface 273a is opposite to the rotation direction of the removal brush 271. Therefore, FIGS. The dust 236 held by the removal brush 271 is scraped off by the dust return preventing brush surface 273a.

The dust 236 thus scraped off is initially held by being mostly entangled with the inclined flocked portion of the dust return preventing brush surface 273a. However, when the cleaning brush 267 next reciprocates, the removal brush 271 and the dust return prevention brush 273 come into sliding contact again. At this time, as shown in FIGS. 8 (f) and 9 (g), new dust 236 gets inside the brush holder 276 by the removal brush 271 and is simultaneously entangled with the inclined flocked portion of the dust return preventing brush surface 273 a. The dust 236 is scraped off by the inner end portion of the removal brush surface 271 a and is further submerged into the brush holder 276. As shown in FIG. 9 (h), the dust 236 that has further submerged reaches the inner end of the dust return preventing brush surface 273a again when the lever protrusion 269 moves over the rotating lever 271c and the removal brush 271 returns to its original state. It is scraped off. As described above, the dust 236 scraped off the inner end of the dust return preventing brush surface 273a is separated from the dust return preventing brush 273 and the removal brush every time the removal brush 271 rotates along with the reciprocation of the cleaning brush 267. The movement between 271 is repeated, and a part of the movement fails and falls into the brush holder 276. As the amount of the dust 236 moving between the dust return prevention brush 273 and the removal brush 271 increases while adding new dust 236 one after another by repeating the rotation of the removal brush 271, the dust return prevention brush 273 and the removal brush are increased. The amount of dust 236 that fails to move between 271 also increases and falls into the brush holder 276 one after another. For this reason, the dust 236 of the circulating air flow filter 231 swept away by the cleaning brush 267 gradually falls into the brush holder 276 and flows backward from the brush holder 276 when viewed at long intervals. There is nothing. Thus, the dust 236 scraped off by the dust return prevention brush 273 is removed from the removal brush 271 shown in FIGS. 8 (e), 8 (f), 9 (g), and 9 (h) after the next time. In the reciprocating operation, when the removal brush 271 is rotated in sliding contact with the inclined flocking direction of the dust return prevention brush surface 273a, and the removal brush 271 is in a direction opposite to the inclined flocking direction of the dust return prevention brush surface 273a. When rotating in sliding contact, it is pushed out into the brush holder 276. As a result, dust 236 accumulates in the brush holder 276. In this way, the dust 236 once swept by the cleaning brush 267 is scraped off by the removal brush 271 and the dust return prevention brush 273, collected in the brush holder 276, and reattached to the surface of the circulating airflow filter 231. There is no. The brush holder 276 has an open bottom, and the bottom opening faces the hopper opening 281a of the removed dust hopper 281.

  Next, the cleaning brush 267 moves while sliding in contact with the circulating air flow filter 231 by deforming the hair tip in the opposite direction to that during cleaning, and moves toward the standby unit 238.

  Next, the removed dust storage unit 284a and the outside air filter storage unit 284b provided in the dust collection box 284 will be described with reference to FIGS. FIG. 10 is a perspective view of the removed dust hopper. FIG. 11 is a perspective view of the dust collection box. 12 is a cross-sectional view taken along the line AA in FIG.

As described above, the removal brushes 271 and 271 ′ are provided with the circulation airflow filter 231 and
In this embodiment, the upper removal brush 271 and the front removal brush 271 'are parallel to the circulation air filter surface on the left side of the upper circulation air flow filter 231 and the front circulation air flow filter 231'. Is provided. A removal dust hopper 281 as shown in FIG. 10 is placed below the upper removal brush 271 and behind the front removal brush 271 ′, and the upper removal brush 271 and the front removal brush 271 ′ are rotated on the removal dust hopper 281. The hopper openings 281a and 281a 'are opened from the upper side to the front side of the removed dust hopper 281 so as to face each of the brush holders 276 and 276'.

  Therefore, the dust 236 scraped by the dust return preventing brush surfaces 273a and 273a ′ inside the brush holders 276 and 276 ′ is pushed by the dust 236 carried one after another, and the dust return preventing brush surfaces 273a and 273a, It leaves | separates from 273a 'and falls in the brush holders 276 and 276'. The dropped dust 236 passes through the opposed hopper openings 281a and 281a ', falls in the removed dust hopper 281 and is collected in the removed dust storage portion 284a of the dust collection box 284 as shown in FIG. A removed dust discharge port 281b is provided in front of the lower portion of the removed dust hopper 281 and a dust collection box 284 is inserted and closed there so that the dust in the dust collection box 284 is not scattered around during normal use. .

  As a result, the dust 236 swept from the circulating air flow filters 231 and 231 'by the cleaning brushes 267 and 267' is scraped off by the removal brushes 271 and 271 'and sent to the dust return prevention brushes 273 and 273'. The dust is stored in the removed dust storage portion 284a of the dust collection box 284 through the openings 281a and 281a '. When the stored dust reaches an appropriate amount, the dust collection box 284 is removed from the removal dust discharge port 281b, and the removed dust is removed. The dust 236 stored in the storage unit 284a is discarded. For this reason, it can suppress that the dust 236 of circulating airflow filter 231 and 231 'scatters inside an air conditioner.

  At this time, as shown in FIG. 12, the removed dust hopper 281 is placed on the front and top of the air conditioner, and an outside air introduction mechanism 32 (see FIGS. 13 and 14), which will be described later, is placed on the back and bottom of the removed dust hopper 281. Put. By arranging in this way, it is possible to simplify the movement path of dust collected by the cleaning mechanism from the circulating airflow filters 231 and 231 ′, which are often installed on the front side and the upper side of the indoor unit 2, and move with less obstacles. It can be a route. As a matter of course, the reliability of the dust collecting operation can be improved by using a moving path with few obstacles.

  Next, the intake operation by the outside air introduction mechanism 32 will be described with reference to FIGS. FIG. 13 is a perspective view of the outside air introduction mechanism.

The outside air introduction mechanism 32 is disposed on one side of the indoor unit 2. Specifically, the outside air introduction mechanism 32 is incorporated on the side opposite to the blower motor 313 for the blower fan 311.

  The outside air introduction mechanism 32 has a suction port 325 of the outside air introduction mechanism that takes in fresh outdoor air at the rear part. A ventilation air passage 39 is connected to the suction port 325 of the outside air introduction mechanism, and this ventilation air passage 39 penetrates through the piping hole of the house together with the refrigerant pipe 8 connecting the indoor unit 2 and the outdoor unit 6 to the outdoor. The tip of the ventilation air passage 39 is opened to the outside air, and the refrigerant pipe 8 is connected to the outdoor unit 6.

  The outside air introduction mechanism 32 has an intake operation state and an operation stop state. In the intake operation, outdoor air is sucked from the suction port 325 of the outside air introduction mechanism and blown out into the room. It should be noted that it is not always necessary to provide an outdoor air outlet that directly blows into the room, and an outlet may be provided at an appropriate position in the circulation path of the circulating airflow, or a clear outlet path may not be provided. As a result, if the air is blown into the room, the purpose of intake can be achieved. Of course, the wind does not flow when the operation is stopped.

  Further, although not specifically described, the switching of each operation mode is performed by the operation unit of the remote controller or the operation unit of the indoor unit 2. In addition, the operation mode can be automatically switched according to the ambient environmental conditions, the operation of the air conditioner, and the like by a command from a control device (not shown). The operation of the outside air introduction mechanism 32 can be operated in combination with the cooling / heating operation of the indoor unit 2 or can be operated by the outside air introduction mechanism 32 alone. Furthermore, a timer may be provided in the outside air introduction mechanism 32 so that the operation is automatically stopped after the operation for a predetermined time.

  In other words, outdoor air is sucked in the intake air operation, and dust having a particle size of 10 μm or more is collected with high efficiency close to 99.9% by the outdoor air filter 327b placed in the middle of the outdoor air intake air passage 328b to obtain clean air. Blow out indoors. As such an outside air filter 327b, for example, an air supply and air cleaning filter having a deodorizing function is known. In this manner, the minute dust and odor contained in the air are removed by the outside air filter 327b and sucked into the outside air introduction fan 321. When the operation is stopped, the outside air introduction fan 321 is stopped and the intake operation is stopped.

  At this time, as shown in FIG. 12, the outside air introduction mechanism 32 is placed on the back and bottom of the air conditioner, and the removed dust hopper 281 is placed on the front and top of the removed dust hopper 281. By arranging in this way, it is possible to simplify the intake ventilation air passage 39 that is often introduced from the rear and lower portions of the indoor unit 2 as with the refrigerant pipe 8 and the drain pipe 37, and is less bent and less resistant. There can be few air paths. As a matter of course, the performance of the outside air introduction mechanism, such as operation noise and introduction air volume, can be improved by using a wind path with less resistance.

  As shown in FIG. 11, the storage section 284b of the outside air filter 327b is provided in the rear half of the dust collection box 284, and is separated from the front removed dust storage section 284a by a partition 284k. The seal 284m is in close contact with the partition opening 281c of the removed dust hopper 281 so that the storage portion 284b and the removed dust storage portion 284a of the outside air filter 327b are completely blocked.

  As described above, the dust collection box 284 is provided with the storage portion 284b of the outside air filter 327b in the rear half, and the front half is a storage portion 284a for removed dust. The front wall of the storage portion 284a is a lid portion 284n that blocks ventilation from the room. The periphery of the reservoir portion 284a is in close contact with the removed dust discharge port 281b by a lid portion seal 284p, and the dust in the removed dust storage portion 284a is scattered in the room. It prevents it from coming. The storage portion 284b of the outside air filter 327b bisects the outside air suction air passage 328b, and the rear portion and the upper portion are opened, and an outside air filter upstream opening 284j and an outside air filter downstream opening 284g are formed. The outside air filter 327b is attached in close contact with the upstream opening 284j, removes dust in outside air to be introduced, cleans it, and supplies it to the room. Further, the periphery of the upstream opening 284j is in close contact with the inner wall of the outside air suction air passage 328b by an upstream opening seal so that the introduced outside air always passes through the outside air filter 327b. The above-mentioned lid seal 284p, partition seal 284m, and upstream opening seal are various such as rubber seal material, sponge seal material, fin seal material or simple butt seal depending on the size of gap to be sealed and gap size variation. However, as a result, when the dust collection box 284 is attached, it is needless to say that the purpose can be achieved if the amount of leakage before and after the seal is suppressed to an air flow rate that does not interfere with use. Yes.

  Reference numeral 328c denotes an outside air passage connection portion for connecting the ventilation air passage 39 to the outside air introduction mechanism suction port 325. The ventilation air passage 39 is connected by a hose band or the like so as not to leak outside air.

  Next, cleaning of the removed dust storage unit 284a and cleaning and replacement of the outside air filter 327b will be described with reference to FIGS. FIG. 14 is a perspective view of the dust collection box attaching / detaching portion.

When the air conditioner is operated and a long time elapses, the circulating airflow filter 231 is repeatedly used.
231 'is cleaned, and the removed dust is collected in the removed dust storage portion 284a. Further, when the outside air introduction operation is performed for a long time, dust accumulates in the outside air filter 327b, and at the same time, the charge amount is reduced and the dust collecting effect is lowered. For this reason, when used in a dusty environment, it is necessary to clean the removed dust storage unit 284a and clean and replace the outside air filter 327b once every two to three years. In the embodiment, the removed dust storage portion 284a and the storage portion 284b of the outside air filter 327b are integrally formed, the front panel 25 is opened as shown by the dotted line in FIG. 12, and the knob portion 284c of the lid portion 284n is pinched and the removed dust discharge port. Pull out from 281b and remove. The removed dust storage portion 284a of the removed dust collection box 284 is cleaned, and at the same time, the outside air filter 327b of the storage portion 284b is inspected and cleaned or replaced. The dust collection box 284 is inserted through the removed dust discharge port 281b, attached, the front panel 25 is closed, and the maintenance of the removed dust storage unit 284a and the outside air filter 327b is completed. In this way, by integrating the components with two different functions, the outside air filter storage part of the outside air introduction mechanism and the removed dust storage part of the cleaning mechanism, the opening for maintenance can be shared, and space saving is possible. It becomes. Moreover, it becomes possible to maintain the two different functions simultaneously by cleaning the integrated parts.

  As described above, according to the embodiment, the replacement of the outside air filter and the cleaning of the stored dust from the circulating airflow filter can be performed at one place.

  For this reason, the air conditioner whose maintenance is simple can be obtained.

  Generally, in an air conditioner with a wall-mounted type, floor-mounted type, or ceiling-mounted type air conditioner, the wall (floor) where the indoor unit is in contact with the refrigerant pipe and drain pipe as well as the outside air pipe in consideration of the aesthetics after installation. It is often introduced into indoor units from the surface and ceiling surface. On the other hand, since the circulation airflow filter is provided at the intake port of room air, it is provided on the surface except the wall surface (including the floor surface and ceiling surface) with which the indoor unit is in contact.

  As a result, the air path for the outside air is on the opposite side of the indoor unit and the wall of the room (including floor and ceiling surfaces), and the dust movement path when cleaning the circulating airflow filter is on the side of the room air suction surface. It can be installed, and it is not necessary to increase the size required for crossing or to increase the size to avoid crossing.

  For this reason, it is possible to obtain an air conditioner that eliminates wasteful arrangement and saves space.

  As a result, it is possible to remove and install the outside air filter that requires regular maintenance such as replacement and cleaning and the dust storage means of the circulating air flow filter that requires regular cleaning, so that both maintenance can be performed at the same time. Convenient.

  For this reason, the air conditioner which improves a user's convenience can be obtained.

  Thereby, the outdoor air filter and the dust storage part can be easily removed from the indoor side together and cleaned.

  For this reason, the air conditioner which a user's convenience improves further can be obtained.
