Problems solved by technology

[0002] The drum washing machine drives the clothes to the top of the inner drum through the rotation of the inner drum, and then lets the clothes fall freely, and achieves the purpose of washing by simulating the beating of the clothes. Therefore, when the user uses the drum washing machine, he can use less water and laundry detergent. The drum washing machine generally only has one water inlet and one drain. During the washing process of the drum washing machine, when there is too much detergent or high-foaming detergent is used, due to agitation and water flow impact washing Because of the detergent and other reasons, the air is in continuous contact with the detergent, and a large amount of foam is generated in the cylinder. As the washing process progresses, especially when the inner cylinder rotates at a high speed during the dehydration process of the washing machine, the foam in the inner cylinder is difficult to burst and will become more and more More bubbles will overflow from the washing machine, affecting the performance and user experience of the washing machine, and causing waste of detergent and water resources

Embodiment 1

[0042] Such as image 3 As shown, the filter screen 3 described in this embodiment is arranged between the inner cylinder 2 and the outer cylinder 1, the filter screen 3 can eliminate the foam between the inner cylinder 2 and the outer cylinder 1, and save water resources and waste of washing water .

[0043] In this embodiment, the filter screen 3 is a sheet-like structure, and the sheet-like structure is parallel to the axis of the inner cylinder 2, increasing the contact area between the filter screen 3 and the foam, effectively eliminating foam, and the sheet-like structure and the radial direction of the inner cylinder 2 have An angle of inclination, preferably, the filter screen 3 is inclined from the side of the outer cylinder 1 to the side of the inner cylinder 2, and to the side opposite to the rotation direction of the inner cylinder 2.

[0044] In this embodiment, the sheet structure is perpendicular to the radial direction of the inner tube 2 .

[0045] In the pr...

Embodiment 2

[0053] Such as figure 1 and figure 2 As shown, a washing machine with a foam removing device described in this embodiment includes an outer cylinder 1 and a rotatable inner cylinder 2 set inside the outer cylinder 1. The drain groove 10 is sunken outside, and the filter screen 3 protruding and extending toward the inner cylinder 2 is installed on the side wall 11 of the drain groove 10 .

[0054] In this embodiment, the inner wall of the outer cylinder 1 is provided with an outwardly recessed drainage groove 10, the drainage groove 10 opens toward the side of the inner cylinder 2, the side wall 11 of the drainage groove 10 is inclined from the bottom wall to the opening, and the slot 12 is provided On the side wall 11 of the drain tank 10, the fixed part 32 of the filter screen 3 is fitted and fixed with the side wall 11 of the drain tank 10; The end of the net 3 extends obliquely toward the drainage groove 10, and the filter mesh 3 extends toward the inner cylinder 2 to be...

Abstract

The invention discloses a washing machine with a defoaming device. The washing machine comprises an outer cylinder and a rotatable inner cylinder arranged inside the outer cylinder in the sleeve mode,and at least one filter screen is arranged between the inner cylinder and the outer cylinder for filtering washing water between the inner cylinder and the outer cylinder to remove foam in the washing water. The defoaming device is added between the inner cylinder and the outer cylinder to remove the foam between the inner cylinder and the outer cylinder and avoid effect on the performance of thewashing machine due to foam overflowing. The washing machine saves water resources and detergents, and improves the user experience.

Description

technical field [0001] The invention belongs to the field of household appliances, in particular to a washing machine with a foam removing device. Background technique [0002] The drum washing machine drives the clothes to the top of the inner drum through the rotation of the inner drum, and then lets the clothes fall freely, and achieves the purpose of washing by simulating the beating of the clothes. Therefore, when the user uses the drum washing machine, he can use less water and laundry detergent. The drum washing machine generally only has one water inlet and one drain. During the washing process of the drum washing machine, when there is too much detergent or high-foaming detergent is used, due to agitation and water flow impact washing Because of the detergent and other reasons, the air is in continuous contact with the detergent, and a large amount of foam is generated in the cylinder. As the washing process progresses, especially when the inner cylinder rotates at ...
