Description

Indoor unit for 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 a filter.

The indoor unit of the air conditioner discharges air heat-exchanged with the refrigerant into the room, thereby adjusting the required indoor temperature. The indoor unit of the air conditioner may suck indoor air through a suction port, exchange heat with a refrigerant, and discharge the heat exchanged air through the discharge port.

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

Since the stand-type indoor unit is disposed so that the discharge port faces the indoor space, the suction port disposed at the rear of the cabinet is disposed to face the wall surface or the corner surface of the indoor space. Accordingly, a filter disposed at the inlet port to filter foreign substances 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 location due to the size or weight of the product or the arrangement of the refrigerant pipe. Therefore, the user has to replace or clean the filter from the cabinet in the rear space of the cabinet. This has a problem that causes inconvenience to the user due to the space limitation of the portion where the inlet is installed.

Chinese Laid-Open Patent CN103008289 discloses a stand-type indoor unit in which a suction port is formed at the rear. A filter is provided at a suction port formed at the rear of an indoor unit, and a filter is disposed at the rear of the filter so as to be movable in the vertical direction of the filter, and a filter cleaner for sucking foreign substances into the filter is disclosed.

However, in the above-described contents, the filter cleaner moving in the vertical direction has a structure that cleans only the area limited 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 to clean both the left and right directions of the filter. Therefore, the above-described Chinese patent application discloses a structure in which the filter is arranged in a horizontal direction.

In addition, as described above, in a structure in which the arrangement of the filter is changed in the left and right direction, the shape of the filter is required to be changed in order to move in the left and right direction in a limited left and right area. Therefore, the Chinese Patent Publication discloses that the filter has a structure that can be deformed at both ends of the left and right sides.

Therefore, in a structure in which the arrangement of the filter is not changed or the shape of the filter is not changed, there is a problem that it is difficult to apply the above contents. In particular, in a filter structure including a dust collector or a deodorizing filter, since the arrangement or shape 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 is a problem that is difficult to apply.

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

The first task to be solved by the present invention is to provide an indoor unit of an air conditioner capable of maintaining cleanly a filter having a fixed arrangement and shape behind the indoor unit. That is, in addition to the filter being cleaned by a user, a separate filter cleaner for cleaning the filter is provided, and the indoor unit of the air conditioner is provided for cleaning while the filter cleaner moves up and down of a fixedly disposed filter.

You may need a process for it. The second task is to solve the problem of brushing off and removing foreign substances stuck in these filters.

In the case of including a configuration for removing foreign matter stuck in the filter, if there is a foreign matter stuck in the above configuration, the foreign matter cannot be completely removed, and thus a problem that foreign matter may be introduced into the indoor space may occur. The third task is to provide an indoor unit equipped with a filter cleaner that removes even foreign matters present in the configuration to remove such a filter.

Foreign matters separated from the filter by the filter cleaner must be introduced 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 required for the suction device may be minimized. A fourth task of the present invention is to provide a filter cleaner having a structure capable of minimizing the amount of power in the suction device.
