BEST MODE FOR CARRYING OUT THE INVENTION

[First Embodiment]

The air conditioner 1 according to the first embodiment of the present invention is a wall-mounted air conditioner arranged on the wall of an air-conditioning target space such as a living room, as shown in FIGS. The air conditioner 1 mainly includes a case 2, a blower fan 3, a loop filter 4, a heat exchanger 5, an open / close panel 8, a dust removal mechanism 9, and a filter support mechanism 10. ing. Inside the case 2 are mainly a blower fan 3 that sucks the air in the room 2 into the case 2 and blows it out from the outlet 7, a filter 4 that filters the air sucked into the case 2, and a blower fan 3. A heat exchanger 5 arranged so as to surround the upper half is arranged.

The blower fan 3 is composed of a cross-flow fan. Air blown into the room 2 is sucked into the case 2 through the suction port 6 of the case 2 and filtered by the filter 4, and then blown out of the conditioned air from the blowout port 7. Generate a flow. The air sucked from the upper surface opening 6a and the front opening 6b of the suction port 6 flows into the heat exchanger 5. In the heat exchanger 5, the air is heat-exchanged with the refrigerant and cooled or heated to become conditioned air. After that, the conditioned air is blown out through the blower fan 3 from the outlet 7 at the lower front of the case 2 to the air-conditioned space such as a living room.

[0023] The heat exchanger 5 has a plurality of heat exchange portions 5a, 5b, 5c. The inclined heat exchange portion 5b is disposed in an inclined manner inside the case 2.

The open / close panel 8 opens and closes the front opening 6 b of the suction port 6. The open / close panel 8 can be reciprocated between a closed position shown in FIG. 2 and an open position shown in FIG. 3 by a reciprocating drive mechanism (not shown) housed in the case 2.

As shown in FIG. 2, the open / close panel 8 closes the front opening 6b so that it is completely invisible from the outside during the non-air-conditioning operation in which the air-conditioning apparatus 1 does not perform the air-conditioning operation. At the same time, since the open / close panel 8 is close to the case 2, the thickness of the entire air conditioner 1 is reduced. As a result, it is possible to improve the design of the air conditioner 1 during non-air-conditioning operation. On the other hand, as shown in FIG. 3, during the air conditioning operation of the air conditioner 1, the open / close panel 8 moves forward by a predetermined distance, so that air can be sufficiently sucked from the front opening 6b. Performance can be secured. In addition, even during the air conditioning operation shown in FIG. 3, the front opening 6b and the filter 4 are hidden from the outside (particularly in front view) by the open / close panel 8, so the design of the air conditioner 1 is also performed during the air conditioning operation. Improved.

The dust removal mechanism 9 is a mechanism that removes dust from the filter 4. The dust removal mechanism 9 includes a force such as a brush for scraping dust from the surface of the filter 4, a scraping means, a suction means for sucking dust from the surface of the filter 4, and a scraping suction means for simultaneously scraping and sucking dust. , Ma Or it has one or more kinds of vibration means to remove dust by vibration. The dust removal mechanism 9 shown in FIGS. 1 to 3 removes dust on both sides of the filter 4. For example, the dust removal mechanism 9 is configured such that when the loop-like filter 4 is scrolled while being supported by the rollers 10a to 10e of the filter support mechanism 10, the filter 4 is removed by scraping means such as a pair of brushes of the dust removal mechanism 9. Remove dust on both sides.

As shown in FIG. 2, the dust removal mechanism 9 is arranged in contact with or very close to the front surface of the heat exchanger 5 during the non-air conditioning operation in which the air conditioner 1 does not perform the air conditioning operation. On the other hand, when the air conditioner 1 performs the air conditioning operation as shown in FIG. 3, the open / close panel 8 moves forward by a predetermined distance, thereby moving away from the heat exchanger 5 than during the non-air conditioning operation. As a result, it is possible to increase the heat exchange efficiency of the heat exchanger 5 while having a dust removal function. In addition, even if the dust removal mechanism 9 is built in, the external shape of the air conditioner 1 during non-air-conditioning operation can be reduced, so that the design of the air conditioner 1 during non-air-conditioning operation can be improved.

[0025] It should be noted that even if the entire dust removal mechanism 9 is not moved, if the portion that comes into contact with or very close to the front surface of the heat exchanger 5 that is at least a part of the dust removal mechanism 9 is moved, It is possible to achieve improvement in heat exchange efficiency and designability.

Also, instead of attaching the dust removal mechanism 9 to the open / close panel 8, the dust removal mechanism 9 can be moved independently so that at least a part of the dust removal mechanism 9 does not perform air conditioning operation during air conditioning operation. You may make it the structure which can leave | separate from the heat exchanger 5 rather than time.

When dust is removed from the filter 4 by the dust removal mechanism 9, it is basically performed with the open / close panel 8 open as shown in Fig. 3, but with the open / close panel 8 closed as shown in Fig. 2. You may do it.

[0026] Further, since the dust removal mechanism 9 is provided in a portion of the loop filter 4 close to the suction port 6, the outer shape of the air conditioner 1 during non-air-conditioning operation shown in FIG. 2 is further reduced. It is possible to

The filter support mechanism 10 includes a drive roller 10a, driven rollers 10b to 10e, a drive unit 13, and a movable bracket 14. The driving roller 10a and the driven rollers 10b, 10c, 10d, and 10e are rotatably mounted inside the case 2 and the open / close panel 8, and support the loop filter 4 so that it can be scrolled. The driving roller 10a is rotationally driven by a driving unit 13 incorporating a step motor or the like. The driven rollers 10b and 10c are rotatably attached to the upper side and the lower side inside the opening / closing panel 8, respectively. The driven roller 10d is rotatably attached to a movable bracket 14 that is attached so as to be slightly movable relative to the case 2. The driven roller 10e is rotatably mounted on the inside upper side of the case 2.

Note that the air conditioner 1 can also be manually scrolled with a force that can automatically scroll the filter 4 by the driving force of the driving unit 13. In order to easily perform manual scrolling, it is preferable to attach an operation handle or an operation knob to any of the rollers 10a to 10e.

As shown in FIG. 1, the loop-shaped filter 4 supported by the filter support mechanism 10 has a net part 4a and a band part 4b. If at least the band part 4b is a loop, the loop-shaped filter 4 is scrolled. Is possible.

The net portion 4a may also be disposed over the entire circumference of the band portion 4b in the same manner as the band portion 4b. In that case, the downstream side (the part hung inside the rollers 10a to 10c in FIG. 2) is more upstream than the net side 4a (the part hung outside the rollers 10a to 10c in FIG. 2). If the mesh is made finer, it is possible to secure the dust collection capacity while suppressing the draft resistance.

[0028] If the follower roller of the filter support mechanism 10 is further added below the front heat exchange portion 5a of the heat exchanger 5, the filter 4 can be disposed so as to cover the heat exchanger 5 below. is there. In this case, the air sucked into the front opening 6b of the suction port 6 from below the opening / closing panel 8 can also pass through the filter 4 reliably.

Even if the dust removal mechanism 9 is built in, the external shape of the air conditioner 1 during non-air-conditioning operation can be reduced, so that the design of the air conditioner 1 during non-air-conditioning operation can be improved. .

[0029] (2)

The air conditioner 1 of the first embodiment further includes an open / close panel 8 that closes the front opening 6b that is at least a part of the suction port 6 during non-air-conditioning operation and opens the suction port 6 during air-conditioning operation, and removes dust. Since the mechanism 9 is provided on the opening / closing panel 8, the dust removal mechanism 9 can be separated from the heat exchanger 5 during the air-conditioning operation by opening / closing the opening / closing panel 8.

(3)

The air conditioner 1 of the first embodiment further includes a filter support mechanism 10 that movably supports the filter 4, and the driven rollers 10b, 10c, and 10d that are part of the filter support mechanism 10 Since it can move together with the removal mechanism 9, it is possible to smoothly remove dust while the filter support mechanism 10 is away from the heat exchanger 5.

[0030] In the first embodiment, the force by which the filter 4 is automatically scrolled by the drive force of the drive unit 13 may be manually scrolled.

In the air conditioner 1 according to the first embodiment, the dust removal mechanism 9 removes dust adhering to both surfaces of the filter 4, so that quick dust removal is possible.

[Modification of the first embodiment]

(A)

In the air conditioner 1 of the first embodiment, the force with which the dust removal mechanism 9 is fixed to the open / close panel 8 is not limited to this. As a modification of the first embodiment, as shown in FIG. 4, the dust removal mechanism 15 moves relative to the filter 4 by moving it. You may make it remove garbage. In this case, dust can be removed more quickly.

[0031] The dust removal mechanism 15 includes scraping means such as a brush, for example, and is attached to the open / close panel 8 so as to be reciprocally movable in a horizontal direction. Moved.

Instead of moving the dust removal mechanism 15 in the horizontal direction, it may be moved in the vertical direction. Furthermore, the dust removal mechanism 15 may be movable in two directions, the vertical direction and the horizontal direction.

(B)

In the air conditioner 1 of the first embodiment, the dust removing mechanism 9 removes dust adhering to both surfaces of the filter 4, but the present invention is not limited to this. As another modification of the first embodiment, the dust removal mechanism 9 may remove dust adhering to one side of the filter 4. In this case as well, the dust on the part where much dust is attached can be effectively removed, and the structure of the air conditioner 1 is simplified.

[0032] (C)

As yet another modification of the first embodiment, the air conditioner 1 may further include a dust storage unit 16 for storing the dust removed by the dust removal mechanism 9 as shown in FIG. Yo! In this case, by storing the garbage in the garbage storage unit 16, it is possible to continuously remove the dust and reduce the number of times the garbage is thrown away.

(D)

Further, it is preferable that the dust container 16 shown in FIG. 5 is detachably attached to the open / close panel 8 or the case 2. In this case, the trash stored in the trash storage unit 16 can be easily discarded, and the trash storage unit 16 can be easily cleaned.

(E)

As still another modification of the first embodiment, as shown in FIGS. 6 (a) and 6 (b), the air conditioner 1 has a dust storage section 16 for storing the dust removed by the dust removal mechanism 9, as shown in FIGS. It is preferably connectable to the suction part S of the machine. In this case, simply connecting the suction part S of the vacuum cleaner to the dust storage part 16, the dust G stored in the dust storage part 16 can be easily sucked and discharged by the vacuum cleaner. It becomes possible.

[0033] As shown in FIG. 6 (b), the dust container 16 shown in FIG. 6 includes an openable / closable shirt 17 and a radially divided rubber so as to be connected to the suction portion S of the vacuum cleaner. And a valve 18 such as a membrane. When the suction part S is pushed in, the shirt 17 opens upward and the valve 18 is also pushed upward to open the valve 18. As a result, the dust G can be sucked out to the vacuum cleaner side by allowing the inside of the dust container 16 and the suction part S to communicate with each other. Further, if the suction portion S is separated from the dust storage portion 16 after the dust G is sucked out, the shirt 17 is closed by an elastic force such as a rotary vane (not shown). At the same time, the valve 18 is closed by its own elastic force.

As still another modification of the first embodiment, the case 2 may be a ceiling-carrying type (so-called ceiling cassette type) air conditioner that is installed by being embedded in the ceiling of the air-conditioning target space.

In this case as well, heat exchange can be performed while having dust removal function by separating at least a part of the dust removal mechanism 9 from the heat exchanger 5 than during non-air-conditioning operation when air-conditioning operation is not performed during air-conditioning operation. The heat exchange efficiency of the vessel 5 can be increased. Even if the dust removal mechanism 9 is built in, the external shape of the air conditioner 1 during non-air-conditioning operation can be reduced, so that the design of the air conditioner 1 during non-air-conditioning operation can be improved. The

[0035] (H) As still another modification of the first embodiment, instead of attaching the dust removal mechanism 9 to the open / close panel 8, the dust removal mechanism 9 can be moved independently so that at least one of the dust removal mechanism 9 can be moved. It may be configured such that the unit can be separated from the heat exchanger 5 during air-conditioning operation, not during air-conditioning operation, or more than during non-air-conditioning operation. In this case as well, the heat exchange efficiency of the heat exchanger 5 and the design of the air conditioner 1 can be improved.

[Second Embodiment]

In the air conditioner 1 according to the second embodiment of the present invention, as shown in FIGS. 8 to 10, the dust removal mechanism 29 is arranged on the upper side of the open / close panel 8 and is in a non-air-conditioning operation ( 9) is different from the air conditioner 1 of the first embodiment in that the dust removal mechanism 29 is housed in the upper part of the inclined heat exchange portion 5b inside the case 2.
