Problems solved by technology

[0004] However, as the washing machine is used for a long time, sometimes the sealing ring will be damaged, deformed or fall off. Further, there will be a gap between the observation window and the sealing ring due to the above problems. When washing clothes, there will be washing water. Leakage from these gaps will not only affect the washing of clothes, but also cause pollution to the surrounding environment of the washing machine. and other issues, and there is a safety hazard of electric shock

Embodiment 1

[0053] In the actual laundry process, the water leakage of the drum washing machine can be divided into water leakage in the water intake stage and water leakage in the washing / rinsing stage according to the washing program stage. This embodiment provides a water leakage judging method and water leakage countermeasures of the drum washing machine of the present invention during the water inflow stage.

[0054] Firstly, when doing laundry, the washing machine starts to take in water, and the water level in the washing tub 2 rises, and when the water level rises to the preset washing water level of the washing machine, it stops the water inflow and starts washing. The reason for the water leakage when entering the water is that there is a gap between the sealing ring 13 and the observation window 31, or the sealing ring is damaged, and when the water leakage gap caused by the above reasons is below the preset maximum water level of the washing machine, when the water is entering ...

Embodiment 2

[0080] Such as Figure 5 As shown, this embodiment provides a water leakage judgment method and water leakage countermeasures of the drum washing machine of the present invention in the washing / rinsing phase.

[0081] In the washing / rinsing stage, the reason for the water leakage is that the water leakage gap between the sealing ring 13 and the observation window 31 is above the preset maximum washing water level. As the washing drum rotates, the washing water is stirred up and down. leakage.

[0082] Further, the water leakage of the washing machine can be divided into slight water leakage and serious water leakage according to the amount of water leakage. The method for judging water leakage in the washing / rinsing stage and the countermeasures for water leakage provided in Embodiment 2 of the present invention are the same as the method for judging water leakage in the water intake stage provided in Embodiment 1. Compared with the countermeasures against water leakage, step...

Embodiment 3

[0090] The drainage mechanism in this embodiment communicates with an external drainage pipeline (not shown).

[0091] When washing clothes, when the washing water leaks, the water receiving box 15 receives the washing water leaking from the leaking hole. Further, the water level detection device detects that the water level in the water receiving box is H>0, and sends out a water leakage information. At this time, the water leakage information According to the first water leakage information, the controller controls the drainage mechanism to start to discharge the leakage water received by the water receiving box 15 through the external drainage pipeline, avoiding the potential safety hazards of electric leakage and electric shock.

Abstract

The invention relates to a roller washing machine and a water leakage judgement method. The roller washing machine comprises a casing with a front panel, a washing cylinder, a controller and a drainage device, and the washing cylinder, the controller and the drainage device are arranged in the casing. The front panel is provided with a recess used for mounting a door body, the center of the recess is provided with a clothes putting port communicated with the washing cylinder, the circumferential wall of the recess is provided with water leaking holes, a water receiver communicated with the water leaking holes is arranged in the casing, a water level detection device is arranged in the water receiver, the water receiver is provided with a draining mechanism, and the controller is connected with the water level detection device, and obtains water leakage information in dependence on the water level change in the water receiver, and executes a water leakage response measure corresponding to the water leakage information. By employing the roller washing machine and the water leakage judgement method, whether water is leaked in the door sealing position of the washing machine can be detected, and a water leakage response measure can be executed in dependence on the water leakage information.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a drum washing machine and a water leakage judging method thereof. Background technique [0002] The front panel of a general drum washing machine is provided with a clothes inlet for putting or taking out clothes into the washing tub, a sealing ring is arranged around the clothes inlet, and a door body for blocking the clothes inlet is also hingedly connected on the front panel. , There is a bowl-shaped observation window on the door. When the door is closed, the observation window and the sealing ring are squeezed tightly to prevent the washing water from leaking out. [0003] The existing drum washing machine solves the problem of washing water leakage by increasing the force between the door body and the sealing ring, and strengthening the close fit between the observation window and the sealing ring. The Chinese patent application number CN03130107.X discloses a drum A tub d...
