BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner having a function of automatically removing dust adhering to a filter, and more particularly to an air conditioner capable of storing collected dust for a long period of time.
[0002]
[Prior art]
A filter for removing dust in the air is provided at the air outlet of the air conditioner (indoor unit). Since dust accumulates on the filter in proportion to the operation time of the air conditioning, and the amount thereof increases, the heat exchange efficiency decreases. Therefore, it is necessary to clean the filter appropriately.
[0003]
Generally, a detachable air filter is provided as in Patent Document 1, and after removing the filter from the indoor unit housing by a customer's hand and removing dust, for example, by hand washing, the filter is manually re-attached to the indoor unit housing. I was trying to wear it on my body.
[0004]
However, since an ordinary air conditioner is installed at a high place in a room, it is difficult for an elderly person or a woman to attach or remove the filter, and thus there is a problem that cleaning work is easily avoided.
[0005]
Then, the proposal of the air conditioner with the cleaning apparatus which automatically cleans a filter as shown, for example in patent document 2 or patent document 3 was made.
[0006]
However, Patent Document 2 employs a method of scraping dust adhering to the filter while moving the brush in the horizontal direction along the flat filter, so that the application is limited to the flat filter. In particular, since the filter of a recent air conditioner is housed by curving or bending the filter surface along with the downsizing of the housing, this patent document 2 cannot cope with it.
[0007]
In Patent Document 3, a filter is pulled out of an air conditioner by a rotating roller, adhering to the filter from a suction cylinder and a suction pipe previously set at the upper part of the outdoor unit, and sucking dust, the filter is then reattached to the air conditioner. In this method, the suction cylinder and the suction pipe must be separately provided outside the housing, and the design as an indoor unit is also lacking.
[0008]
Furthermore, in the method for storing the dust removed from the filter, for example, as shown in Patent Document 4, a filter is stretched between the winding-type cylindrical rollers, and the dust adhering to the filter is removed. There is a method of removing it together with the filter winding operation.
[0009]
However, in the case of this patent document 4, since the dust adhering to the filter is rolled up together and stored in the filter storage unit, the filter is disposable and must be wound in a large amount, resulting in high cost. The result was a burden on customers. In addition, the filter housing portions must be provided on both sides of the housing, and there is a problem that the size of the entire indoor unit is increased, which is contrary to downsizing.
