Problems solved by technology

[0010] However, after the epoxy resin 14 of the water quality detection device designed in the prior art is used for a long time, the tightness is reduced, or due to being damaged by external vibration and impact force, when the sealing is reduced, the washing water will pass through the electrode sensor 8 and The gap between the sensor holes 6 flows out, and the electrode sensor 8 is energized by the water flowing into the sensor housing 4, which causes the electrode sensor 8 to fail to correctly

Embodiment Construction

[0025] The water quality detection device of the washing machine of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0026] Such as image 3 , 4 As shown, the washing machine usually injects detergent and washing water into the outer tub 52, and puts the laundry into the inner tub with the washing wheel built in, and uses a motor (not shown in the figure) to rotate the inner tub and the washing wheel (not shown in the figure) Clothes are washed by the action of water flow and detergent.

[0027] Here, an air box 54 integrally formed with it is formed below the side of the outer tub 52, and an access hole 56 is provided on one side of the connection between the air box 54 and the outer tub 52 to facilitate the ingress and egress of washing water.

[0028] The washing machine water quality detection device designed by the present invention is as image 3 , 4 As shown, it includes: a sens...

Abstract

A water quality detecting device of washer consists of transducer shell set on outer cylinder, a pair of electrode transducer for detecting out washing water conductivity, protective rib for protecting electrode transducer, temp transducer for detecting out washing water temp and protection rib for protecting temp transducer. The leakage water is leaked out at internal side of protective rib down wards to protect the electrode transducer when leakage is occured.

Description

technical field [0001] The invention relates to a detection device of a washing machine, in particular to improving the structure of the water quality detection device of the washing machine, and preventing the electrode sensor from being conductive due to the leaked washing water inside the casing. Background technique [0002] Generally, a washing machine is a device that uses appropriate detergent and mechanical force to remove stains on foreign objects. After putting the laundry into the inner tub with built-in washing wheels, inject detergent and washing water into the outer tub, and use the motor to rotate the inner tub and the washing wheel. , and then through the process of washing, rinsing, and dehydration to wash the clothes. [0003] The so-called water quality is a term that expresses the strength of water. Water with high hardness contains insoluble magnesium ions or calcium ions, which reduces the cleaning ability of detergents. This kind of water cannot be use...
