Embodiment approach 1
[0086] 1 to 8 illustrate an attachment portion of an air filter provided in the indoor unit of the related air conditioner according to Embodiment 1 of the present invention.
[0087] As shown in Figure 1, the air filter for removing dust contained in the air flowing into the heat exchanger, which is arranged on the upstream side of the heat exchanger (not shown in the figure), consists 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 is provided. 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 s...
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] In Fig. 10, a cross-sectional view of another modified example of the suction belt 9 is shown. By making the surrounding part of the suction hole 11, for example, 0.2mm thick, even the suction belt...
