It should be noted that, the usage of the detergent water feeding assembly and the water path on-off structure is only exemplary, and in the practical application process, the specific usage may be further adjusted, for example: the step S9 is executed first, and then the steps S1 to S8 are executed, and this adjustment and change of the usage of the detergent water feeding assembly and the water path on-off structure do not limit the washing device of the present invention.

Referring to fig. 2 to 5 again by taking the water passage opening/closing structure as the third diaphragm valve 33 as an example, the water level detection means 5 is provided in the storage member 32, and the water level detection means 5 can detect the water level inside the storage member 32. The water level detecting member 5 is connected to a controller (not shown) of the pulsator washing machine, and during the process of filling water into the storage member 32 (the first diaphragm valve 42 is in an open state, the first three-way valve 43 is in a state where only the first inlet 4301 is communicated with the outlet 4303, and the second three-way valve 44 is in a state where only the second outlet 4402 is communicated with the inlet 4403), when the water level detecting member 5 detects that the water level in the storage member 32 reaches a preset water level, the controller controls the first diaphragm valve 42 to close, thereby avoiding the occurrence of excessive water filling into the storage member 32, avoiding the increase of the internal pressure of the storage member 32, causing damage to the storage member 32 (if the storage member 32 is a storage tank), and avoiding the liquid from overflowing from the storage member 32 into the tank 1 to cause a short circuit of electronic components (if the storage member 32 is a storage tank with an open upper portion).

Of course, the water level detection member 5 may also be disconnected from the controller, for example: the water level detection member 5 is configured to have a microcontroller and a buzzer such as a single chip microcomputer, and when the water level detection member 5 detects that the water level in the storage member 32 reaches a preset water level, the single chip microcomputer starts the buzzer to prompt a user that the third diaphragm valve 33 needs to be closed to stop water injection into the storage member 32.

With continued reference to fig. 2 to 5, the retention member 32 is further provided with an overflow pipe 6 (an embodiment of an overflow portion), at least a part of the overflow pipe 6 is disposed in the retention member 32, an outlet 4303 of the overflow pipe 6 communicates with the water containing member 31, and when the water level in the retention member 32 reaches a predetermined level, the detergent water in the retention member 32 can flow out through the overflow pipe 6 into the water containing member 31. Thus, even if the water level detecting member 5 is damaged and the water level cannot be detected correctly, when the detergent water in the retention member 32 is excessive, the detergent water can flow out into the water containing member 31 through the overflow pipe 6, thereby preventing the retention member 32 from being damaged by an increase in the internal pressure of the retention member 32 or the detergent water from the retention member 32 from overflowing into the case 1 to cause a short circuit of the electronic component.

Except that overflow pipe 6, the overflow portion also can adopt overflow hole etc. and the concrete structure of overflow portion can be set up in a flexible way to the technical staff in the field of the field in practical application, and this kind does not constitute to the adjustment of the concrete structure of overflow portion with the change the utility model discloses a restriction, all should be injectd within the protection scope of the utility model.

In addition, only the water level detection member 5 or only the overflow portion may be provided to the retention member 32, and those skilled in the art can select the water level detection member or the overflow portion flexibly in practical use.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
