BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner such as a ceiling mounted type.

[0002]

2. Description of the Related Art An example of a conventional ceiling-mounted air conditioner is shown in FIG. Case body 16 buried in the ceiling 10
Inside the heat exchanger 13, drain pan 17, fan motor 1
8, a fan 14, a baffle plate 23, an air filter 15, etc. are built in, and a ceiling panel 19 is attached to the lower part of the case body 16. A suction port 11 and a blowout port 12 are formed in the ceiling panel 19.

During operation of this air conditioner, refrigerant from an outdoor unit (not shown) circulates in the heat exchanger 13 and the fan motor 18 drives the fan 14. Then, the room air in the room 20 flows from the suction port 11 through the suction grill 22 and the air filter 15 as shown by a solid arrow, and dust contained in the room air is captured in this process. Next, this air is guided by the baffle plate 23, enters the fan 14 and is energized, and is cooled or heated in the process of passing through the heat exchanger 13 to become conditioned air, which is blown out from the outlet 12 to the louver. The wind direction is regulated by 21 and the air is blown into the chamber 20.

When the operating time of the air conditioner becomes long, the air filter 15 is clogged with the captured dust. Then, the flow resistance of the indoor air increases and the capacity of the air conditioner decreases. Therefore, when the clogging of the air filter 15 is detected or when the operation time of the air conditioner reaches a preset time, after removing the ceiling panel 19, the air filter 15 is taken out and cleaned. It was

[0005]

In the conventional air conditioner described above, the ceiling panel is cleaned every time the air filter 15 is cleaned.
19 and the air filter 15 must be removed and attached, which requires a lot of time and labor. Moreover, this work is difficult because the work is performed at a high place, and there is a problem that if there is a product display stand or the like under the air conditioner, it must be removed.

[0006]

The present invention has been proposed to solve the above problems, and its gist is to provide a fan for driving a fan that sucks indoor air through an intake port. In an air conditioner equipped with a motor and an air filter for filtering indoor air passing through the suction port, a long air filter wound around a winding core, and a winding roll that winds the air filter, An air conditioner is provided with a motor for rotationally driving the winding roll and a control means for rotating the motor only when the fan motor is in operation.

[0007]

In the present invention, since the take-up roll is driven to rotate only when the fan motor is in operation due to the above-described structure, the long air filter is wound from the winding core by being taken up by the take-up roll. The indoor air that is sequentially drawn out and passes through the suction port is filtered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIGS. As shown in FIG. 1, a suction port is provided in the case body 16.
A cassette type filter unit 1 is detachably attached so as to be located behind 11. As shown in FIG. 2, the filter unit 1 includes a disposable long air filter 2, a shaft core 3 around which the air filter 2 is wound in advance, a winding roll 4 for winding the air filter 2, It is composed of a motor 5 for rotating the winding roll 4 and a cassette case 6.

An opening 6a is formed in the center of the cassette case 6, a cover portion 3b for covering the winding core 3 is formed on one side thereof, and a cover portion 6c for covering the winding roll 4 is formed on the other side thereof. The winding core 3 is housed in the cover portion 6b, and the winding roll 4 is housed in the cover portion 6c. The winding rolls 4 extend in parallel to each other at intervals and are rotatably supported. The motor 5 is fixed to the cassette case 6, and its rotation shaft is linked to one end of the winding roll 4. Then, when the filter unit 1 is incorporated into the case body 16, the opening 6a of the cassette case 6 is parallel to the back of the suction grill 22 with a slight gap therebetween, and the winding core 3 is provided on one side of the suction port 11. The winding roll 4 is located on the other side.

FIG. 3 shows an electric control circuit of the motor 5. The motor 5 is connected in parallel with the fan motor 18, and the operation switch 7 is turned on to energize the fan motor 18 and at the same time energize to rotate at a predetermined speed. Other configurations and operations are similar to those of the conventional one shown in FIG. 4, and corresponding members are designated by the same reference numerals and the description thereof is omitted.

When the operation switch 7 is turned on,
The fan motor 18 and the motor 5 rotate, and the winding roll 4 is driven accordingly and winds up the air filter 2 at a predetermined speed.

[0012]

In the present invention, the long air filter is wound around the winding core, and the air filter is automatically wound only when the room air sucked by the fan passes through the suction port. As a result, the frequency of replacing the air filter can be greatly reduced.
