Drum displacement sensor and water level and drum displacement integrated detector comprising drum displacement sensor

Abstract

The invention discloses a drum displacement sensor and a water level and drum displacement integrated detector comprising the drum displacement sensor. The drum displacement sensor can transform the displacement of an outer drum of a washing machine in deviating from an equilibrium position into an inductance value variation; the integrated detector comprising the drum displacement sensor integrates the water level detection of the washing machine and the drum displacement detection of the washing machine into one, except for detecting the water level, the integrated detector can also detect the displacement of the outer drum of the washing machine in deviating from the equilibrium position, and can judge whether drum collision occurs or not and the drum collision degree, thus a CPU takes a corresponding regulation measure, the problem in the prior art that the drum collision degree of the washing machine cannot be detected is solved, and thus the washing machine is used to the maximum limit.

Description

[0001] Technical field [0002] The invention relates to a washing machine, in particular to a bucket level sensor and a water level and bucket level integrated detector comprising the bucket level sensor. Background technique [0003] In the traditional washing machine, the water level sensor and the barrel collision signal detection are separated. This detection technology has the disadvantages of high cost and large installation space. For example figure 1 The bucket and water level integrated sensor developed for Hangzhou Shenlin Electronics Co., Ltd. includes an air cover (101) and a housing (102). An elastic diaphragm (103), a diaphragm plate (104) is embedded in the middle of the elastic diaphragm, and an iron core (105) is installed in the middle of the diaphragm plate. The iron core can move axially with the elastic diaphragm in the skeleton. An inductance coil (106) is wound on the frame, a circuit board (111) is connected to the housing, a sensing circuit is arran...

Problems solved by technology

[0004] In order to overcome the problem that the degree of bucket collision in the washing machine cannot be detected in the prior art, the present invention provides a bucket position sensor, which converts the displacement of the outer bucket of the washing machine relative to the equilibrium position (that is, the bucket position) into a first adjustable The inductance value, according to the inductance value of the first adjustable inductance, can determine whether the washing machine has hit the bucket and the degree of the collision
