Drum washing machine

Abstract

The invention discloses a drum washing machine, which comprises: a box body, a washing bucket, a suspension spring, a photoelectric sensor and a control device. The washing bucket is rotatably arranged in the casing. The two ends of the suspension spring are respectively connected with the upper part of the inner wall of the casing and the outer wall of the washing tub. The upper end of the photoelectric sensor is connected to the top wall of the box or the upper part of the inner wall of the box, and the lower end of the photoelectric sensor is connected to the outer wall of the washing bucket. The photoelectric sensor is configured to output an electrical signal when the position of the washing bucket changes. The control device is connected with the photoelectric sensor to receive the electric signal from the photoelectric sensor. According to the drum washing machine of the embodiment of the present invention, by connecting the photoelectric sensor between the box body and the washing tub, the photoelectric sensor is configured to output an electrical signal when the position of the washing tub changes, and the control device can judge the position of the washing tub according to the electrical signal. Weight change, so that the weight change of the washing tub can be monitored more accurately in real time, so as to control the drum washing machine to run more smoothly.

Description

technical field [0001] The invention relates to the laundry field, in particular to a drum washing machine. Background technique [0002] During the use of the drum washing machine, different water intake and different laundry volumes will cause different weights of the drum washing machine. At the same time, during the washing process of the drum washing machine, the weight of the drum washing machine will also vary However, none of the drum washing machines in the related art can detect the weight of the drum washing machine in real time, so that it is impossible to control and judge the running process of the drum washing machine according to the weight change of the drum washing machine. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a drum washing machine that monitors the weight change of the washing tub i...
