Problems solved by technology

[0007] In this method, in order to clean the entire surface of the air filter, a long slit-shaped suction hole with a length equivalent to the total length of the air filter is provided on the suction nozzle, and the dust attached to the air filter is sucked and removed through the suction hole. , but in the case of suction from all the suction holes, the suction air volume becomes larger, the output of the suction device becomes very large, not only consumes a lot of power, but also it is difficult to build the suction device inside the main unit of the indoor unit. question

Embodiment approach 1

[0086] Figure 1 to Figure 8 The attachment part of the air filter provided in the indoor unit of the air conditioner related to Embodiment 1 of this invention is demonstrated in .

[0087] Such as figure 1 As shown, the air filter configured on the upstream side of the heat exchanger (not shown in the figure) and used to remove dust contained in the air flowing into the heat exchanger is composed of a filter frame 1 and a filter screen 2. A suction nozzle device 3 capable of moving along the surface of the air filter. The suction nozzle device 3 can move smoothly left and right while maintaining an extremely narrow gap with the air filter through the guide rails 4 provided at the upper and lower ends of the filter frame 1 . The dust attached to the air filter is sucked off by the suction nozzle device 3 .

[0088]One end (lower end) of the suction nozzle device 3 is connected with one end of the suction air duct 5 formed by a flexible excellent bellows hose etc. ) The suc...

Deformed example 1

[0101] The thickness of suction belt 9 is preferably as thin as possible, by making suction belt 9 thinner can guarantee the softness of its curved part (especially the top end and the root of suction nozzle device 3), thereby can carry out suction smoothly. The driving action of the dust belt 9. In addition, by making the suction tape 9 thinner, the suction tape 9 other than the suction hole 11 is tightly attached to the nozzle opening 10 due to the suction force, thereby sealing, and suction leakage other than the suction hole 11 can be suppressed and suction leakage can be prevented. The resulting reduction of the suction force on the suction hole 11 . From above-mentioned aspect and aspects such as durability, strength, preferably use thin plastic film as dust-absorbing belt 9. However, in the case of using a thin suction belt, it may not be able to withstand the tension during driving due to the reduction in the strength of the suction belt. In this case, by making a pa...

Deformed example 2

[0104] On the basis of the shape of Modification 1, increasing the thickness of the dust-absorbing belt 9 around the suction hole 11 provided on the dust-absorbing belt 9 is also beneficial to improving the strength of the dust-absorbing belt 9 . As mentioned above, it is preferable to use a thin plastic film for the suction belt 9, and if a thin plastic film is used, the belt may not be able to withstand the tension during driving due to the reduced strength of the suction belt. In particular, the strength of the suction belt 9 in the part where the suction holes 11 are located is significantly reduced. In this case, by making the periphery of the suction hole 11 thick, the strength of the suction belt 9 at the portion where the suction hole 11 is located can be increased.

[0105] Figure 10 , shows a cross-sectional view of another modified example of the suction belt 9. By making the surrounding part of the suction hole 11 thick, for example, 0.2 mm, sufficient strength c...

Abstract

Suction is gathered up into a suction hole by arranging a driveable belt with small suction holes opened thereon in the suction nozzle, and output of the suction device can be largely reduced by reducing the suction air volume while maintaining strong suction force. A sucking place is also varied by moving the suction holes by driving the belt, and the whole air filter area is cleaned by performing sweeping operation on the air filter in response to operation of the suction nozzle.

Description

technical field [0001] The present invention relates to an air conditioner having a function of automatically cleaning an air filter provided at an air suction port of an indoor unit. Background technique [0002] In previous air conditioners, an air filter was installed in front of the heat exchanger of the indoor unit to prevent dust from entering the interior of the main unit of the indoor unit. Clean up the attached dust. Not only does such an air filter require frequent maintenance, but the air filter is gradually clogged until the maintenance is performed, and as a result, the air volume passing through the heat exchanger decreases, the air conditioning capacity decreases, and the power consumption increases. [0003] Therefore, in order to reduce the burden of maintenance of the air filter, someone proposes to provide a belt-shaped air filter hung on the drive shaft and a rotating brush in contact with the surface of the air filter, and the air is blown while rotatin...
