[0034] figure 1 is a schematic diagram of a drum washing machine according to the present invention, figure 2 for along figure 1 The cross-sectional view obtained by the line I-I'.

[0035] refer to figure 1 and figure 2 The main body 100 of the washing machine in which the drum and the tub are installed and the door 114 formed on the front side of the main body 100 constitute the appearance of the washing machine of the present invention. The detergent box 120 and the controller 111 are installed on the upper portion of the main body 100 .

[0036] The main body 100 has a case 103 fixed between the upper plate 101 and the lower plate 102 to form a predetermined space therein. Various components required to operate the washing machine, such as the driving motor 170 and the drum 140, etc., are installed inside the casing 103 of the washing machine. The driving motor 170 rotates the driving shaft 171 using an electric current supplied externally to operate the washing ma...

[0059] The second embodiment of the present invention is the same as the first embodiment except that the method of spraying air to the filter is different from the first embodiment. Therefore, the difference in the second embodiment will be mainly explained below, and the explanation of the same parts in the first embodiment will be referred to.

[0060] Figure 4 is a sectional view of a washing machine according to a second embodiment of the present invention, Figure 5 Yes Figure 4 Enlarged view of part "B" in .

[0061] refer to Figure 4 and Figure 5 , The lint removing unit 200 has a nozzle 230 connected to the ventilation duct 130, and the ventilation duct 130 has an opening / closing valve 240 for switching the flow direction of the air compressed by the fan 132 therein. The opening / closing valve 240 is installed at the rear side of the connecting portion between the ventilation duct 130 and the nozzle 230 so that the air blown by the fan 132 can flow toward the ...

[0067] The third embodiment is the same as the second embodiment except that the injection part of the nozzle 230 is different from the second embodiment. Specifically, by distributing the jet of air over a wider area, lint can be removed more effectively.

[0068] Image 6 is a sectional view of a washing machine according to a third embodiment of the present invention, Figure 7 for Image 6 Enlarged view of part "C" in .

[0069] refer to Image 6 and Figure 7 , the nozzle 230 has a discharge end including at least one branch toward the entire rear surface of the filter 300 . Since the nozzle 230 is branched as described above, compressed air is sprayed to the entire surface of the filter 300 . Therefore, it is possible to effectively remove the lint accumulated on the entire surface of the filter 300 .

[0070] This solution can be directly applied to the first embodiment.

Abstract

The invention provides a washing machine and a control method thereof. The washing machine contains an exhaust, filter and nozzle. The humid air in the tub is exhausted to the outside through the exhaust port. The exhaust port is provided with a filter to filter lint. The nozzle sprays air into the filter. Since the lint filtered out by the filter can be automatically removed, the convenience and safety of use are enhanced, and the drying efficiency of the washing machine is improved.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine and a control method thereof, which can solve the problem of lint caused by clothes. More specifically, the present invention relates to a drum washing machine and a control method thereof, which can improve the convenience of use by accumulating lint and automatically removing the accumulated lint. Background technique [0002] A general drum washing machine includes a main body having a hexahedron shape, a drum installed in the main body and having a plurality of holes, a tub surrounding the drum and containing wash water, a driving motor for rotating the drum; A detergent box for detergent, a water pipe connected to the detergent box for supplying washing water or washing water mixed with detergent in the detergent box, a drain pipe for draining the washing water during a washing cycle, and a A pump and drain hose connected to the end of the drain pipe for forced dischar...
