Description

Indoor unit of air conditioner {Indoor Unit for Air Conditioner}

The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner including a filter cleaner for cleaning filters.

An indoor unit of an air conditioner discharges air that has undergone heat exchange with a refrigerant into the room, thereby adjusting a required room temperature. The indoor unit of the air conditioner may take in indoor air through a suction port, exchange heat with a refrigerant, and discharge the heat-exchanged air through a discharge port.

The indoor unit of the air conditioner may be classified into a ceiling type, a wall-mounted type, and a stand type depending on the installation location. In the stand type indoor unit, a discharge port may be formed in the front or side of the cabinet, and a suction port may be formed in the rear side of the cabinet.

Since the outlet of the stand-type indoor unit is disposed toward the indoor space, the suction port disposed at the rear of the cabinet is disposed to face a wall or corner surface of the indoor space. Accordingly, a filter disposed at the suction port for filtering foreign matter may also be disposed on the rear surface of the cabinet.

In the case of a stand-type indoor unit, it is difficult to change the installed position due to the size or weight of the product or the arrangement of refrigerant pipes. Therefore, the user has to replace or clean the filter from the cabinet in the rear space of the cabinet. This has a problem of causing inconvenience to the user due to spatial limitations of the portion where the inlet is installed.

Chinese Patent Publication CN103008289 discloses a stand-type indoor unit in which a suction port is formed at a rear side. Disclosed is a filter cleaner in which a filter is disposed at a suction port formed at the rear of an indoor unit, and disposed at the rear of the filter so as to be movable in the vertical direction of the filter, and sucks foreign substances into the filter.

However, in the above disclosure, the filter cleaner moving in the vertical direction has a structure in which only a limited area is cleaned in the left and right directions. In a structure including such a filter cleaner, a structure in which the filter moves in the left and right directions is required in order to clean both the left and right directions of the filter. Therefore, the above Chinese Patent Publication discloses a structure in which the filter is arranged in the left and right directions.

In addition, as described above, in the structure in which the arrangement of the filters is changed in the left and right directions, the shape deformation of the filters is required to move in the left and right directions in the limited left and right areas. Therefore, in the Chinese Patent Publication, it is disclosed that the filter can be deformed in shape at both left and right ends.

Therefore, there is a problem in that it is difficult to apply the above content in a structure in which the arrangement of the filter is not changed or the shape is not changed. In particular, in a filter structure including a dust collector or a deodorization filter, since the arrangement or deformation of the filter is extremely limited, it is difficult to apply to various types of filters, and even in a structure in which a plurality of types of filters are used together, the above contents There are problems that are difficult to apply.

In addition, the filter cleaner disclosed in the above Chinese Patent Publication discloses a method of removing foreign substances caught in the filter by a suction method. Since a filter is a device that chemically or physically filters out flowing foreign substances, it is unreasonable to remove the trapped foreign substances only with the flow of air.

The second task is to solve the problem of brushing and removing foreign substances caught in such a filter.

In the case of including a configuration for shaking off foreign substances caught in the filter, if there is a foreign substance buried in the above configuration, since the foreign substance is not completely removed, it may also cause a problem that the foreign substance may flow into the indoor space. A third task is to provide an indoor unit equipped with a filter cleaner that removes even foreign substances present in such a filter-shaking configuration.

Foreign matter that has fallen from the filter by the filter cleaner must flow into the dust bin to prevent contamination of the indoor space. To this end, a suction device that sucks air into the dust bin can be used. However, in the case of a structure capable of moving foreign substances to the dust bin without using the suction device, the amount of power consumed by the suction device can be minimized. A fourth object of the present invention is to provide a filter cleaner having a structure capable of minimizing the power consumption of a suction device.
