Description

  The present invention relates to an indoor unit of an air conditioner provided with means for automatically removing dust captured from room air by an air filter from the air filter and discharging it to the outside.

  In an indoor unit of an air conditioner, room air sucked into a main body through a suction port is passed through an air filter, and dust contained in the room air is captured by the air filter and then guided to a heat exchanger. Therefore, if the air-conditioning operation is continued for a long period of time, dust accumulates on the air filter, resulting in flow resistance of room air to the heat exchanger, and heat exchange efficiency is reduced.

Therefore, it is necessary to periodically remove the air filter and remove the adhering dust. However, since a general indoor unit can be installed at the height of the wall surface of the room, it may be difficult for some users to attach and remove the air filter. Along with. For this reason, for example, [Patent Document 1] discloses an air conditioner including means for automatically removing dust adhering to an air filter.

  When the operation is stopped, the movable panel 2A is joined to the surface of the front panel 2 to become the same surface and closes the front suction port 4. However, during operation, the movable panel 2A protrudes and displaces to the front, creating a gap communicating with the room. The front suction port 4 is controlled to be opened indoors. An upper surface suction port 5 is provided in the upper part of the indoor unit body 1. A frame-like crosspiece is fitted into the upper surface suction port 5 and is partitioned into a plurality of spaces by the crosspiece.

  A blow-out opening 6 is opened at the front lower portion of the indoor unit body 1, and two blow-out louvers 7a and 7b are provided in parallel in the blow-out opening 6. The blowout louvers 7a and 7b can open and close the blowout opening 6 according to their respective rotation postures and set the blowout direction of the heat exchange air according to operating conditions.

  In the indoor unit body 1, a heat exchanger 8 formed in a substantially inverted V shape by the front heat exchanger portion 8A and the rear heat exchanger portion 8B is disposed. An electric component box 9 provided with a control unit (control means) R for controlling all electric components housed in the indoor unit main body 1 is provided side by side.

  The front heat exchanger portion 8A is formed in a curved shape substantially parallel to the front panel 2 with a gap therebetween, and faces the front suction port 4 and the upper suction port 5, while the rear heat exchanger portion 8B is straight. And is inclined obliquely and opposed to the upper surface suction port 5. An indoor fan 10 is disposed between the front and rear heat exchanger portions 8A and 8B of the heat exchanger 8.

  The indoor blower 10 includes a fan motor disposed in a space on one side end of the indoor unit main body 1 and a cross-flow fan in which one support shaft is mechanically connected to the rotation shaft of the fan motor. The other support shaft of the cross-flow fan is supported by a bearing member, and an exhaust device 11 described later is provided at a position adjacent to the bearing member.

  The lower end portion of the front heat exchanger portion 8A is placed on the front drain pan 12a, and the lower end portion of the rear heat exchanger portion 8B is placed on the rear drain pan 12b. The front and rear drain pans 12a and 12b receive drain water dropped from the respective heat exchanger portions 8A and 8B, and can drain the water to the outside through a drain hose (not shown).

  The outer surfaces of the side walls of the front and rear drain pans 12a and 12b are provided close to the indoor blower 10 and constitute a nose for the crossflow fan of the indoor blower 10. A partition wall member 14 connects the side wall portions of the front and rear drain pans 12a and 12b, which are noses, and the side portions of the outlet port 6. A space surrounded by the partition wall member 14 is a blowout ventilation path 15 that communicates the nose and the blowout opening 6.

  On the other hand, a frame assembly 16 is interposed between the front panel 2 and the front surface side to the upper surface side of the heat exchanger 8, and the frame assembly 16 is attached to the front panel 2 via an attachment. A front air filter 17 that is divided into left and right parts and an air cleaning unit 18 that is a secondary air filter are attached to the front part of the frame assembly 16 in the front-rear direction. An upper air filter 20 divided into left and right parts is attached to the upper surface of the frame assembly 16.

  An air filter cleaning unit S is provided between the upper end of the front air filter 17 and the front end of the upper air filter 20. The air filter cleaning unit S is formed to have the same length in the width direction as the length in the width direction of each of the air filters 17 and 20, and has a certain thickness dimension in the front-rear direction. The air filter cleaning unit S is disposed in a corner portion that is a dead space where the front surface portion and the upper surface portion of the front panel 2 intersect.

  A front air filter moving mechanism 52 is connected to the front air filter 17. The moving mechanism 52 drives the front air filter 17 upward from the position shown in the figure based on the control signal from the control unit R, passes through the air filter cleaning unit S, and places a predetermined interval on the upper surface position of the upper air filter 20. Exist and face each other. Further, the front air filter 17 is driven downward to pass through the air filter cleaning unit S and is controlled to return to the original position again.

  An upper air filter moving mechanism 53 is connected to the upper air filter 20. The moving mechanism 53 drives the upper air filter 20 downward from the position shown in the figure based on the control signal from the control unit R, passes through the air filter cleaning unit S, and keeps a predetermined interval at the front surface position of the front air filter 17. And make them face each other. Further, the upper air filter 29 is driven to rise and pass through the air filter cleaning unit S, and is controlled to return to the original position again.

  The air cleaning unit 18 includes a pair of left and right electric dust collectors 22 arranged side by side and a dust collector power supply unit 23 arranged on one side. Each electrostatic precipitator 22 is designed to have the same size and shape, and includes a charge-side electrode that gives electric charge to the dust in the flowing air, and a dust-collection side electrode that captures the charged dust. Each electrode surface is coated with a deodorizing agent that adsorbs odorous components contained in the air, and has both a dust collecting function and a deodorizing function as an electric dust collector.

  The air filter cleaning unit S accommodates a rotating brush 30 that removes dust adhering to the front and upper air filters 17 and 20 and collects dust removed by the rotating brush 30 (dust receiving portion) 31. A dust box 32 having an opening 33, an opening 33 provided on the lower surface of the dust box 32 from which a part of the rotating brush 30 is exposed, and a seal member 34 that can open and close the opening 33.

  The dust box 32 is molded using an antistatic resin material and is subjected to antibacterial treatment. Therefore, it is possible to prevent the adhesion of dust and the generation of mold and maintain a clean state for a long time. Similarly, the antibacterial treatment of the rotating brush 30 can be used to prevent adhesion of dust and generation of mold and maintain a clean state for a long time.

  Further, a smooth surface treatment is applied to the dust contact portion so that the movement of the dust within the dust box 32 is smooth. In particular, the dust receiving passage 31 is configured so that the pressure loss is kept small in the actual dust removing operation and the flow of wind is smooth. By forming a curved surface of R2 mm or more on the windward side of the ridge line in the dust receiving passage 31, it is possible to reliably prevent the occurrence of problems such as dust being caught and not moving.

  The seal member 34 is disposed at a lower portion of the opening 33 so as to face the opening 33 and is formed of a flexible elastic material such as synthetic rubber. The seal member 34 closes the opening 33 only when the exhaust device 11 is operated, and does not come into contact with the rotating brush 30 exposed from the opening 33 during the air conditioning operation and when the air filter cleaning unit S is operated. It is supported by the lift mechanism W so as to open.

  Further, a scraping protrusion 35 is provided between the dust receiving passage 31 in the dust box 32 and the portion where the rotary brush 30 is accommodated. The scraping protrusion 35 is always inserted into the bristles of the rotary brush 30 along the axial direction of the rotary brush 30 and is in a position where the bristles are in sliding contact with the rotation of the rotary brush 30.

  In particular, as shown in FIG. 2, the side of the air filter cleaning unit S opposite to the side where the exhaust device 11 is connected (the side on which the electrical component box 9 is attached) is rectangular on the upper surface of the dust box 32. A shaped air inlet 36 is opened. The intake port 36 is in a position communicating with the dust receiving passage 31 and a lid 37 is attached to be openable and closable.

  On the side of the dust box 32, a drive mechanism 38 connected to the lid 37 is provided in parallel. The drive mechanism 38 is composed of, for example, an electromagnetic solenoid and is electrically connected to the control unit R. Therefore, the intake port 36 can be opened and closed by reciprocating the lid 37 connected to the operating rod by a control signal sent from the control unit R.

FIG. 3 is a perspective view of a part of the indoor unit body 1 on the exhaust device 11 side, and FIG. 4 is a schematic configuration diagram of the indoor unit.
A dust discharge box 40 is integrally attached to a side portion of the dust box 32 constituting the air filter cleaning unit S. The dust discharge box 40 is provided at the end of the dust receiving passage 31 and communicates with the intake port 36 through the dust receiving passage 31. One end of a guide hose 42 is connected to the dust discharge box 40, and the dust box 32 communicates with the exhaust device 11 through the guide hose 42.

  The other end of the guide hose 42 is connected to a damper case 44 including a wind damper 43 that constitutes the exhaust device 11. One end of the wind damper 43 is rotatably supported by the damper case 44 via the support shaft u, and the other end hangs down into the damper case 44 due to gravity, thereby closing the damper case 44. That is, when a negative pressure is applied to the damper case 44, the wind damper 43 rotates to open the damper case 44.

  The damper case 44 is integrally projected on a peripheral surface of a fan casing 46 in which an exhaust fan 45 is rotatably accommodated. A fan motor 47 as a drive source of the exhaust fan 45 projects from one side of the fan casing 46, and a ventilation suction port 48 and an auxiliary ventilation suction port (not shown) are opened on the opposite side surface. The ventilation suction port 48 and the auxiliary ventilation suction port can be freely opened and closed by an open / close damper 49 connected to a damper drive mechanism.

  The indoor air sucked into the indoor unit body 1 from the front suction port 4 and the upper suction port 5 in accordance with the operation of the indoor blower 10 passes through the front and upper air filters 17 and 20, and the front and rear heat exchanger parts. Distribute 8A and 8B. If the space before flowing through the front and rear heat exchanger sections 8A and 8B is called a primary space, and the space after flowing is called a secondary space, the ventilation suction port 48 is connected to the secondary space. Oppositely, the auxiliary ventilation suction port is provided to face the primary space.

  Based on a control signal from the controller R, the damper drive mechanism that drives the open / close damper 49 opens the ventilation suction port 48 and guides the secondary side air after passing through the heat exchanger 8 to the exhaust fan 45, Alternatively, the primary air before the auxiliary ventilation suction opening is opened and after passing through the upper air filters 17 and 20 and before being led to the heat exchanger 8 is led to the exhaust fan 45, or the ventilation suction inlet 48 and the auxiliary ventilation suction are introduced. Causes both mouth and mouth to close.

  The fan casing 46 has an exhaust port a, and an exhaust duct 50 is connected to the exhaust port a. The exhaust duct 50 penetrates the mounting wall surface K of the indoor unit body 1 and protrudes outdoors. Therefore, the secondary side air can be discharged to the outside depending on the position of the open / close damper 49, or the primary side air can be discharged to the outside, or the air that has passed through the dust discharge box 40 with the wind damper 43 opened can be discharged to the outside. It can be done.

Next, the operation of the indoor unit of the air conditioner configured as described above will be described.
When the user presses the operation button on the remote control (remote control panel), the indoor blower 10 is driven and the air cleaning unit 18 is activated. Further, the compressor is driven in the outdoor unit communicating with the indoor unit via the refrigerant pipe, and the refrigeration cycle operation is started.

  The room air is guided into the indoor unit body 1 from the front suction port 4 and the upper suction port 5 and passes through the front air filter 17 and the upper air filter 20. At this time, dust contained in the room air is captured by the air filters 17 and 20. The room air from which the dust has been removed by the front air filter 17 passes through the electrostatic precipitator 22 constituting the air cleaning unit 18, and finer dust is electrically collected and deodorized.

The cleaned indoor air flows through the heat exchanger 8 and performs a heat exchange action with the refrigerant led to the room air. After that, the heat exchange air is guided along the blowout ventilation path 15, guided from the blowout opening 6 to the blowout louvers 7a and 7b and blown into the room, and the efficient air conditioning operation is continued.
The user selects the “air filter cleaning mode” by operating the remote control (remote control panel), or after the air-conditioning operation is completed every predetermined period, or a preset time, or a predetermined time zone, etc. In addition, the “air filter cleaning mode” is automatically performed.

  As the air filter cleaning mode is selected, the control unit R operates the front air filter moving mechanism 52 to gradually drive the front air filter 17 upward. At the same time, the air filter cleaning unit S is operated, and the seal member 34 connected to the lift mechanism W opens the opening 33 of the dust box 32. Therefore, the front air filter 17 is inserted through a gap formed between the dust box 32 and the seal member 34.

  Further, the rotary brush 30 is driven to rotate and comes into sliding contact with the front air filter 17 that has moved upward. The dust adhering to the front air filter 17 is smoothly and reliably scraped off and removed by the rotating brush 30. Dust is transferred from the front air filter 17 to the rotary brush 30, but immediately after this, the rotary brush 30 contacts the scraping projection 35 and passes therethrough. The scraping projection 35 scrapes the dust transferred to the rotary brush 30 into the dust receiving passage 31.

  At this time, the air inlet 36 provided on one side of the dust receiving passage 31 is closed by the lid 37, the exhaust fan 45 of the exhaust device 11 is stopped, and the wind damper 43 closes the damper case 44 to guide it. The hose 42 and the dust discharge box 40 are closed with respect to the dust receiving passage 31. That is, since the structure other than the opening 33 of the dust box 32 has a sealed structure, the scraped dust does not scatter from the dust receiving passage 31 to the periphery.

  The front air filter 17 is guided to the upper side of the upper air filter 20 while dust is removed by the rotating brush 30. When the predetermined position is reached, the control unit R temporarily stops the front air filter moving mechanism 52, and then reversely controls the front air filter 17 to return to the original position.

  Although all dust is removed from the front air filter 17 by the dust removing action, dust may still remain on the front air filter 17 depending on conditions. However, since the rotary brush 30 is also in sliding contact when the front air filter 17 is moved downward, all remaining dust is reliably removed. When the front air filter 17 returns to the original position, the control unit R then sends a drive signal to the upper air filter moving mechanism 53.

  The upper air filter 20 moves downward to the front side and sequentially passes through the air filter cleaning unit S. Dust adhering to the upper air filter 20 is smoothly and reliably scraped off and removed by the rotating brush 30. The dust is transferred from the upper air filter 20 to the rotary brush 30. Immediately after this, the rotary brush 30 contacts the scraping projection 35 and the transferred dust is scraped off to the dust receiving passage 31.

  When the upper air filter 20 faces the front side of the front air filter 17, the control unit R temporarily stops the upper air filter moving mechanism 53, and then reversely controls the upper air filter 20 to return to the original position. . Since the rotary brush 30 is in sliding contact with the upper air filter 20 ascending, all the remaining dust is reliably removed.

  When the automatic cleaning operation for removing dust adhering to the front air filter 17 and the upper air filter 20 is completed in this way, the control unit R sends a drive signal to the lift mechanism W to open the opening 33 of the dust box 32. Close. Then, a control signal is sent to the exhaust device 11 to drive the fan motor 47 of the exhaust fan 45, and the ventilation suction port 48 and the auxiliary ventilation suction port are closed by the open / close damper 49.

  Since the exhaust port a is always open, negative pressure is applied to the wind damper 43 as the exhaust fan 45 rotates, and the wind damper 43 rotates to open the damper case 44. The negative pressure acts on the air filter cleaning unit S via the guide hose 42 and the dust discharge box 40. That is, negative pressure is applied from the dust discharge box 40 to the dust receiving passage 31.

  At the start of the operation of the exhaust device 11, the lid 37 still closes the intake port 36, and the dust receiving passage 31 is in an open state only at the 40 side end. Moreover, since a negative pressure is applied to the open end portion of the dust discharge box 40 as the exhaust fan 45 is driven, the dust box 32 changes to a negative pressure state in which the pressure difference from the atmosphere gradually increases.

  After a predetermined time has elapsed since the exhaust device 11 started operation, the control unit R sends a control signal to the drive mechanism 38 that drives the lid 37 to open the intake port 36. Therefore, air is suddenly introduced into the dust box 32 from the intake port 36, and almost instantaneously changes from the negative pressure state to the atmospheric pressure. As a result, air with relatively high pressure introduced instantaneously from the intake port 36 is conveyed at a high speed toward the exhaust device 11 in the dust box 32.

  Specifically, air with a relatively high pressure and high flow velocity is conveyed toward the dust discharge box 40 in the dust receiving passage 31 communicating with the air inlet 36. Therefore, the dust in the dust receiving passage 31 is guided to the dust discharge box 40 side by the momentum of the air flow. All the dust is guided from the dust discharge box 40 to the fan casing 46 via the guide hose 42 and further discharged to the outdoors via the exhaust duct 50.

  In this way, at the start of the operation of the exhaust device 11, the dust box 32 is substantially sealed so as to be in a negative pressure state, and the control for opening the intake port 36 after a predetermined time has been performed at least once. Preferably, the control of opening again after a predetermined time after the intake port 36 is closed with the lid 37 and the inside of the dust box 32 is substantially sealed to increase the negative pressure condition may be repeated a plurality of times.

  By closing the intake port 36, a large pressure difference can be taken between the inside and outside of the dust box 32, and the inside of the dust box 32 is in a significantly negative pressure state compared to the atmosphere. After that, if the lid 37 is driven to open the intake port 36, the energy of the pressure difference can be used for dust discharge in the dust receiving passage 31. Dust collected in the dust receiving passage 31 is reliably discharged in a short time.

  In the above embodiment, the air inlet 36 that is opened and closed by the lid 37 is provided only on the side of the dust box 32 constituting the air filter cleaning unit S opposite to the side where the exhaust device 11 is connected. However, the present invention is not limited to this.

FIG. 5 is a schematic configuration diagram of an air filter cleaning unit Sa as a modified example.
That is, in the dust box 32 constituting the air filter cleaning unit Sa, the first air inlet 36A is provided on the side opposite to the side where the exhaust device 11 is connected, and the first air inlet 36A. The second intake port 36 </ b> B is provided at an intermediate position closer to the exhaust device 11. A first lid 37A is attached to the first air inlet 36A so that it can be opened and closed, and a second lid 37B is attached to the second air inlet 36B so that it can be opened and closed.

  Although not particularly illustrated, a first drive mechanism 38A is connected to the first lid 37A, and a second drive mechanism 38B is connected to the second lid 37B, and the respective drive mechanisms 38A, 38B are connected. Is electrically connected to the controller R. Accordingly, the first drive mechanism 38A and the second drive mechanism 38B can open and close the first lid body 37A and the second lid body 37B in response to the control signal from the control unit R, respectively.

  The first intake port 36A and the second intake port 36B are both closed at the start of the operation of the exhaust device 11, but after the predetermined time has elapsed, either the first intake port 36A or the second intake port 36B is closed. Only one of them is opened. Further, after the elapse of a predetermined time from the start of operation, the first drive mechanism 38A and the second drive mechanism 38B are controlled so that the opened intake port is closed and the other intake port is opened.

Specifically, either the control shown in FIGS. 6A and 6B or the control shown in FIGS. 7A and 7B is employed.
That is, at the beginning of the operation of the exhaust device 11, the first intake port 36A and the second intake port 36B are closed, so that the inside of the dust box 32 is in a negative pressure state, and the pressure difference from the atmosphere is large. Become. After the predetermined time has elapsed, only the first air inlet 36A is opened as shown in FIG. Further, after a predetermined time has elapsed, as shown in FIG. 6B, the first drive mechanism 38A and the second drive mechanism are closed so that the first intake port 36A is closed and the second intake port 36B is opened. 38B is controlled.

  As a result, first, dust existing in a part of the dust receiving passage 31 in the dust box 32 far from the exhaust fan 45 is conveyed and discharged to the outside through the exhaust fan 45. At this time, it is conceivable that part of the dust in the dust box 32 does not reach the exhaust fan 45 and stays on the side of the dust box 32 close to the exhaust fan 45.

  Even in such a situation, the first intake port 36A is closed next, and the second intake port 36B provided on the side close to the exhaust fan 45 is opened, so that the flow velocity flowing therethrough is high. Dust that stays on the air can be taken away. Eventually, all the dust in the dust receiving passage 31 is efficiently discharged to the outside and is not affected by adverse conditions.

  Alternatively, when the operation of the exhaust device 11 is started, the first intake port 36A and the second intake port 36B are closed, and the pressure inside the dust box 32 is reduced to increase the pressure difference from the atmosphere. After the predetermined time has elapsed, only the second air inlet 36B is opened as shown in FIG. 7A, and after the predetermined time has passed, the second air inlet 36B is closed as shown in FIG. 7B. At the same time, the first drive mechanism 38A and the second drive mechanism 38B are controlled so as to open the first intake port 36A.

  That is, since the dust receiving passage 31 in the dust box 32 is extremely long in the longitudinal direction as compared with the width direction, the first intake port 36A is opened and the dust at the end is sucked to the exhaust fan 45 side at once. When trying to do so, it is conceivable that dust collects in the middle of the dust receiving passage 31 and becomes a large lump.

  Therefore, first, the second air inlet 36B is opened, dust on the side close to the exhaust fan 45 is discharged first, and after almost no dust is present at this portion, the second air vent 36B is provided on the side far from the exhaust fan 45. By opening the one air inlet 36A and discharging the dust, all the dust can be efficiently discharged to the outside so that the dust does not become a large mass, and it is not affected by adverse conditions.

  Furthermore, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments.
