Air conditioner having indoor unit with automatic air filter celaning function

Abstract

An air conditioner, wherein a heat exchanger and a fan blowing air heat-exchanged in the heat exchanger into a room are stored in an indoor unit body, and an air filter is installed in the body on the upstream side of the heat exchanger. Also, the air conditioner comprises a sucking and exhausting device in which a suction nozzle having a suction port facing the air filter and sucking dirt adhered to the air filter is slidably fitted, communicating with the suction nozzle, and sucking and exhausting the dirt together with the air.

Description

technical field [0001] The present invention relates to an air conditioner provided with a function of automatically cleaning an air filter provided at an air suction port of an indoor unit. Background technique [0002] Conventional air conditioners such as Figure 28 as well as Figure 29 As shown, on the front of the heat exchanger 11, an air filter 6 for preventing dust from entering the main body 13 is provided, and the air filter 6 is detachably configured so that the attached dust can be cleaned by hand. [0003] Moreover, as an air conditioner that is easy to clean the air filter, it is provided with: a rotating brush; a brush cover that rotatably supports the rotating brush and covers the rotating brush; and a filter brush that is coaxial with the rotating brush. The suction nozzle of the electric vacuum cleaner is connected to the suction port provided on the brush cover, and moves on the air filter, and sucks while scraping off the dust accumulated on the air fil...

Problems solved by technology

[0009] However, in conventional air conditioners equipped with detachable air filters, depending on the frequency of use of the air conditioner, it is necessary to remove the air filter from the air conditioner and periodically perform maintenance such as washing with water or removing adhering dust with a vacuum cleaner. thus very troublesome

In addition, if periodic maintenance is not performed, there is a problem of reducing the performance of the air conditioner and increasing power consumption due to the accumulation of dust on the air filter to increase the ventilation resistance of the intake air.

[0010] Moreover, in the content disclosed in Patent Document 1, it is necessary to take out the electric vacuum cleaner every time the air filter is cleaned, connect its suction nozzle to the suction port of the brush cover, and move it on the air filter, which is very troublesome. and time-wasting issues

[0011] Moreover, in the case of the filter described in Patent Document 2, the dust attached to the air filter is automatically sucked, but since the sucked dust is collected by the separator, it is necessary to periodically remove and process the dust accumulated on the separator, which is not only troublesome. , and if you forget to deal with it, the dust adhering to the air filter will not be removed, and the ventilation resistance of the sucked air will increase, resulting in a decrease in the performance of the air conditioner and an increase in power consumption.

[0012] In addition, in the case of the air conditioner disclosed in Patent Document 3, a long brush having approximately the same length as the full width of the air filter is required, and the thickness of the air filter may be increased due to the band shape of the air filter, and the depth of the main body may become large.
