Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0019] see in conjunction figure 1 and figure 2 As shown, according to the embodiment of the present invention, the foam detection method of the drum washing machine includes: step S1: enter the washing program; step S2: turn on the electric heater 1 for heating, and detect the frequency of the water level; step S3: convert the detected water level The frequency is compared with the reference frequency of washing, and according to the comparison result, it is judged whether the foam is excessive.

[0020] In the present invention, the water level sensor 4 is combined with the electric heater 1 to judge whether there is excessive foam in the washing cycle, and the heating of the electric heater 1 can be used to accelerate the foam breaking to make the water level change frequency more...

Abstract

The invention discloses a roller washing machine and a foam detection method thereof. The foam detection method of the roller washing machine includes the steps that a washing program is executed; an electric heater (1) is turned on to conduct heating, and water level frequency is detected; the detected water level frequency is compared with washing reference frequency, and whether foam is excessive or not is judged according to a comparison result. The foam detection method of the roller washing machine can solve the problem that in the prior art, excessive foam is prone to leak out of the washing machine in the washing process of the washing machine.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a drum washing machine and a foam detection method thereof. Background technique [0002] Current washing machines generally have the problem of generating a large amount of foam during the washing cycle and leaking to the outside of the washing machine. The leaking foam can cause a short circuit of the electrical components inside the washing machine, resulting in potential safety hazards and reducing the reliability of the washing machine; excessive foam will also cause pressure on the inner cylinder Increase, the phenomenon of motor overload, so the excess foam must be eliminated during the washing process. Contents of the invention [0003] Embodiments of the present invention provide a drum washing machine and a foam detection method thereof to solve the problem in the prior art that excessive foam easily leaks out of the washing machine during washing. [0004] ...
