Watertight structure of device for detecting wash water for washer

Abstract

A water-proofing structure for the washing water detector of washer is composed of casing with open lower end and flange, and lower cover for said casing and with flange, and the sensors in said casing for detecting the information about the washing water. It features that the water proofing slot with a certain depth and made on the flange of said casing and the water-proofing plug made on the flange of said lower cover are matched to prevent water vapor from coming in the casing.

Description

technical field [0001] The present invention relates to a washing machine, in particular to a waterproof structure of a washing water detection device for detecting the hardness, temperature and detergent amount of the washing water. Background technique [0002] A general washing machine utilizes the water flow of the washing water and the softening action of the detergent when the inner tub rotates to clean the laundry. A washing water detection device is arranged on the outer tub of the washing machine. This washing water detection device has the function of detecting the hardness, temperature and detergent amount of the washing water, and controlling the washing machine to achieve the best washing conditions. [0003] Below, combine Figure 1 to Figure 2 The washing water detecting device provided on the outer tub of the conventional washing machine will be described in detail. [0004] refer to figure 1 and figure 2 It can be seen that the washing water detection d...

Problems solved by technology

[0013] In such a process, due to the wrong operation of the water supply device, continuing to supply water during the operation of the washing machine will cause the water to overflow the outer tub

Moreover, the vortex generated when the washing machine performs the washing program or the dehydration program will cause the washing water to overflow the outer tub

[0014] However, the washing water detection device designed in the prior art simply uses the binding force of flanges 11, 21 to close the gap between the casing main body 10 and the cover 20, so the water overflowing the outer tub will pass through the gap between flanges 11, 21. The gap between them enters the inside, thus causing leakage of electrical components such as connectors on the sensor 30

[0015] Moreover, washing machines are generally installed in places with relatively high humidity, so as the moisture generated in this environment invades the inside of the sensor, the hidden danger of electric leakage at the electrical connection will always exist.

Not only that, due to the leakage of the sensor may cause the user to get an electric shock
