Washing machine

Abstract

A washer of the invention, a foam detecting sensor of which has a grounding side electrode (35) and a detecting side electrode (36) that are arranged projected to a wind path (31). Each electrode (35, 36) is composed of a cylinder with a large diameter. A front end is circular and in semi-spherical shape. Furthermore, a projection of the electrode (35, 36) is limited to enable the diameter of theelectrode (cylinder) to be equal to that of the projection. Pile of a thrum isotropic electrode (35, 36) is reduced, which reduces occurrence of mis-action of the foam detection. An improved washer is further realized. The foam detecting sensor on a recycle wind path of air in a recycle processing groove is composed of velveteen that is hard to adsorb and thrum and so on, which reduces the occurrence of mis-action of the foam detection.

Description

technical field [0001] The invention relates to washing machines such as fully automatic washing machines and drum washing machines. Background technique [0002] For washing machines, it is well known that a drying function is given. A washing machine with a drying function has a well-known structure that has a circulating air passage. During the drying operation, the circulating air passage extracts the air in the washing machine tank, and heats the extracted air while dehumidifying, and makes the heated air The air is returned into the washing tub (for example, refer to paragraph [0034] of Patent Document 1). [0003] The circulation air path is a path for circulating the air in the washing tub during drying, but water used for washing and foam generated through washing processing often enter during washing. For this reason, a configuration is also known in which a pair of electrodes are provided on the circulating air path as means for detecting incoming water and foam...

AI Technical Summary

Problems solved by technology

[0009] In particular, when using a foam detection sensor that detects the presence or absence of foam through the conduction between a pair of electrodes, the distance between a pair of electrodes is close, and the electrodes will adhere to each other. Lint and lint, etc. During the next washing, regardless of whether the foam enters the circulation air path, the lint and thread attached to the electrodes will cause conduction between the electrodes, and thus, it was also clarified that the false detection of foam entering topic

[0010] In addition, in the above-mentioned patent document 2, the shape of the glass window of the opening and closing door has been studied, but it should be improved so that the laundry in the rotating drum will not be entangled, and There is room for the glass window of the constitution that covers the entrance and exit of the rotary drum tightly
