Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an air conditioner equipped with a filter device for removing dust from the air.

BACKGROUND TECHNOLOGY A conventional air conditioner (hereinafter referred to as an air conditioner) installed buried in the ceiling includes a heat exchanger 21, a fan 22, a fan motor 23,
The box body 26 consists of an orifice ring 24, a dew pan 25, a box body 26 in which these are placed and housed, a decorative panel 27 with air inlets and outlets, and a sheet-like filter 28. Place the decorative panel 2 buried in the ceiling and attach it to this box.
7 is installed.

In such an air conditioner, when the sheet-shaped filter 28 becomes clogged with dust as described above, it is common to take the filter 28 out of the air conditioner, wash it, and reuse it.

Problems that the invention aims to solve: However, in such air conditioners that are installed buried in the ceiling, the single sheet-shaped filter 28 does not have a large filter area, gets clogged in a short period of time, and has to be cleaned frequently. There is a need to. However, there was a problem in that a stepladder or the like was required to attach and detach the filter 28, which was time-consuming.

Means for Solving the Problems Accordingly, the present invention includes a filter device in which a band-shaped filter is formed into a bellows shape, folded closely together, and stored in a storage frame biased to one side.

Function With the above configuration, the filter is formed from a band-shaped filter into a bellows shape, which can be stored in a large amount in close contact with each other.
The part used as a filter has a bellows shape, so the filter area is large, and compared to conventional single sheet filters, it does not get clogged for a long time. Since it can be folded and stored in close contact with each other, there is no need to check for filter clogging, and it also saves the effort of cleaning.

Embodiment An embodiment of the present invention will be described below based on the accompanying drawings. In Figure 1, 1 is a heat exchanger, 2
3 is a fan, 3 is a motor for the fan, 4 is an orifice ring, 5 is a dew pan, and 6 is a box body in which these are appropriately arranged and stored, and the bottom surface thereof is open. Reference numeral 7 denotes a decorative panel having air inlets and outlets, which is installed exposed outside the ceiling and attached to the lower surface of the box body 6. A rectangular frame 9 is housed in the air suction chamber 8 formed between the decorative panel 7 and the orifice ring 4, and a band-shaped filter 10 is molded into a bellows shape inside the chamber and folded tightly. The portion that is stored biased to one side (a in the figure) and acts as a filter (b in the figure) is fixed by protrusions 9-1 (four locations) inside the frame so that it can maintain a bellows shape. The part of the filter 10 that is used is the part that faces the storage part (see c in the figure).
Pull it up and store it.

According to the configuration of the above embodiment, by sequentially pulling and storing the used portion c of the filter 10 at one end of the frame 9, a new portion b can be automatically pulled out to the center. This eliminates the need for cleaning each time as in the conventional method.

Effects of the invention As is clear from the above explanation, according to the present invention, a large number of filters are formed in a bellows shape and folded closely together in the frame, and the filter portion through which air passes is shaped like a bellows. Since the filter area is larger than the conventional one-sheet type, it is less likely to get clogged, and if the filter becomes clogged, it is fed sequentially, which saves the trouble of checking and cleaning the filter for clogs. can.
