Problems solved by technology

[0007] However, the foam removal method of the drum washing machine in the prior art can only rely on the water level of the washing water detected in the water level detection sensor to judge whether the foam is produced or not. When the water level returns to the set water level, residual detergent components may also be left in the laundry. Therefore, after washing, rinsing and dehydration, foam may be generated again, and there is a problem that the washing cannot be completed smoothly.

Embodiment Construction

[0017] The foam removal method of the drum washing machine of the present invention will be described in detail with reference to the accompanying drawings and embodiments.

[0018] Such as figure 2 As shown, the foam removal method of the drum washing machine of the present invention is first, before washing in the first stage, put detergent into the washing tank 10 at a set water level and open the water supply valve 18 to supply washing water. (Refer to S1 and S2)

[0019] at this time, figure 2 Unspecified reference numbers are used with the above figure 1 same reference number.

[0020] The second stage is when the washing water in the first stage is supplied according to the set water level, and the washing is carried out according to the set time. (Refer to S3 and S4)

[0021] The third stage is to detect the concentration of detergent dissolved in the washing water after the set time of the second stage has passed. (Refer to S5 and S6)

[0022] At this time, t...

Abstract

The invention provides a foam removing method for a cylinder washing machine, which primarily includes the following steps: 1. supplying water and detergent to the washing groove before washing; 2. washing according to the predetermined time after the water is supplied to the predetermined water level; 3. detecting water dissolved detergent concentration after washing in predetermined time; 4. comparing the detected detergent concentration to the predetermined one, then washing in accordance with one of multiple predetermined washing methods. Said method detects the detergent concentration in the washing course to judge whether the foams produce or not, if the detergent concentration is under the set value, then washing with ordinary washing method; otherwise, washing with water level, washing time and mode changed washing method. So the invention can prevent foam production during washing to improve the washing performance.

Description

technical field [0001] The invention relates to a method for removing foam from a drum washing machine, in particular to a method for removing foam from a drum washing machine which detects whether foam is generated during the washing process and forms washing, rinsing and dehydration processes in the state of completely removing the foam. Background technique [0002] A washing machine is a machine in which the drum in the washing machine rotates when the power is turned on to remove dirt and the like attached to the clothes. Drum washing machines put detergent, washing water, and laundry into the horizontal drum, and use the friction between the drum that is driven by the motor to rotate and the laundry to wash, so that the laundry is hardly damaged and the laundry is They will not be entangled with each other, achieving the washing effect of patting and scrubbing. [0003] figure 1 It is a cross-sectional view of the drum washing machine structure in the prior art, incl...
