Problems solved by technology

Therefore, there is a problem that when dust is sucked to the upper part and the lower part of the air filter with the same suction air volume, uneven dust removal occurs, depending on the situation, the upper part of the dust remains, and the lower part uses more than necessary suction. Air volume, consumes excess electricity

Embodiment approach 1

[0055] figure 1 It is a cross-sectional view of the indoor unit of the air conditioner of the present invention. Inside the indoor unit main body 2, a heat exchanger 4, a fan 6, and a filter device 8 arranged on the upstream side of the heat exchanger 4 are accommodated, wherein the fan 6 passes heat exchange The device 4 inhales indoor air and blows out the air that has been heat-exchanged by the heat exchanger 4 into the room, and the action of the fan 6 sucks in air from a plurality of suction ports, which are formed from the front of the main body 2 to the top and float on the air The dust in the air is removed by the filter device 8 arranged between the suction inlet and the heat exchanger 4 .

[0056] In addition, as shown in FIG. 2 , the filter device 8 that removes dust from the air passing through the heat exchanger 4 includes a filter frame 10, a filter screen 12 that holds the filter frame 10, and a suction device that slides freely along the surface of the filter s...

Embodiment approach 2

[0071] Figure 10 and Figure 11 The suction nozzle 14A installed in the indoor unit of the air conditioner according to Embodiment 2 of the present invention is formed on a belt 24 wound around the outer periphery of the nozzle main body 22 to cover the first nozzle opening 22a, and to suck dust. The first suction hole 24a (for example, width 5mm, height 50mm), the installation mode of belt 24 is to make the first suction hole 24a be positioned at the top of the first spout opening 22a.

[0072] In addition, on both sides of the first nozzle opening 22a near the upper end of the nozzle main body 22, a pair of second nozzle openings 22b of a predetermined length are formed, and on the belt 24, between the first suction holes 24a A pair of second suction holes 24b having a predetermined length are formed on both sides.

[0073] The air conditioner of the present embodiment has a cleaning mode for sucking dust adhering to the filter screen 12, a suction duct dust exhaust mode ...

Abstract

An air conditioner having an indoor unit in which a heat exchanger and a fan for blowing out air that is subjected to heat exchange by the heat exchanger are received. In the air conditioner, there is provided a filter device that is constructed from a filter net for removing dust in the air passing the heat exchanger, a suction nozzle drivable in a first direction, along the filter net, and a suction device connected to the suction nozzle. The suction nozzle has a nozzle body having an opening and a belt having suction holes, the belt being driven in a second direction orthogonal to the first direction, along the opening while covering it. Further, a position detection means for detecting the position in the second direction of the suction holes is installed to enable cleaning performance of the suction nozzle to be changed depending on the position of the suction hole detected by the position detection means.

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] In the existing indoor unit of the air conditioner, the air filter for preventing the intrusion of dust into the main body is arranged in front of the heat exchanger, and the air filter is detachably installed on the filter frame so that the attached dust can be removed. dust. Not only does the filter device of this configuration require frequent maintenance, but the air filter is gradually clogged until the maintenance is performed. As a result, the air volume passing through the heat exchanger decreases, the air conditioning capacity decreases, and the power consumption increases. . [0003] Therefore, an air conditioner with an automatic cleaning function that regularly cleans dust adhering to the air filter with a brush has been proposed for the purpos...
