Liquid level sensor for washing machine and washing machine

Abstract

The invention discloses a liquid level sensor for a washing machine and a washing machine. The liquid level sensor includes: a base, a display panel, a straight guide column, a spiral guide column, a pointer and a floating block. The upper end of the straight guide post is connected to the display panel and the lower end is connected to the base; the upper end of the spiral guide post is rotatably connected to the display panel and the lower end is rotatably connected to the base; The pointer is connected to the spiral guide post so as to rotate driven by the spiral guide post; the floating block has first and second through holes, the straight guide post passes through the first through hole, and the floating block The block can move along the straight guide post, and the spiral guide post passes through the second through hole so that the spiral guide post rotates driven by the floating block. The liquid level sensor for the washing machine according to the embodiment of the present invention has a simple structure, can detect the height of the liquid level in real time, and can effectively obtain the storage status of the detergent in the washing machine.

Description

technical field [0001] The invention relates to the technical field of household appliance manufacturing, in particular to a liquid level sensor for a washing machine and a washing machine with the liquid level sensor. Background technique [0002] Many of the existing fully automatic washing machines have applied detergent automatic feeding devices. The general structure is: a detergent storage box is set in the washing machine, and detergent is pre-stored in the detergent storage box; a set of pumping system is set at the same time. When adding detergent, the detergent in the detergent storage box is put into the washing tub through the pump liquid system to participate in washing. Usually, the work of the pumping system is controlled by the main controller of the washing machine or the independent controller of the automatic feeding device to realize automatic operation. [0003] However, based on considerations such as aesthetics, the detergent storage boxes are arrange...

AI Technical Summary

Problems solved by technology

[0003] However, based on aesthetic considerations, the detergent storage boxes are arranged inside the body of the washing machine and cannot be seen from the outside

Therefore, it is impossible to judge the remaining amount of detergent with the naked eye.

First of all, it is impossible to visually check the real-time remaining amount of detergent, and the user cannot purchase laundry detergent in advance, and it is very inconvenient to prepare for adding liquid; secondly, it is impossible to know whether the laundry detergent should be filled up every time when adding laundry detergent, which often causes laundry detergent. Too much liquid is added and flows out of the storage container mouth; thirdly, when the laundry liquid is about to be used up, the user cannot be prompted to add laundry liquid, resulting in poor laundry effect
