Clothes dryer electrostatic protection circuit and clothes dryer

Abstract

The invention belongs to the technical field of electrostatic processing, and discloses a clothes dryer electrostatic protection circuit and a clothes dryer. The clothes dryer electrostatic protectioncircuit comprises two metal strips arranged in a clothes dryer roller, each metal strip is connected with a transient voltage suppression diode in series, the transient voltage suppression diode is aunidirectional transient voltage suppression diode, a cathode of the diode is connected to the metal strip, an anode of the diode is arranged in a grounding manner, and the diode is used for conducting the static electricity of the metal strips into the ground. The clothes dryer comprises the clothes dryer electrostatic protection circuit. Through the unidirectional transient voltage suppressiondiodes for serial connection and grounding with the metal strips, on one hand, the static electricity of the metal strips can be conducted into the ground so that the damage to electrical elements including a computer board of the clothes dryer by the static electricity of the metal strips is avoided; on the other hand, in the conditions of live-line of a ground wire and live-line of an overall housing, the unidirectional transient voltage suppression diode can prevent power supply clutters from being directly conducted to the computer board through a wire so that severe distortion of data acquisition is avoided.

Description

technical field [0001] The invention relates to the technical field of electrostatic treatment, in particular to an electrostatic protection circuit for a clothes dryer and a clothes dryer. Background technique [0002] Most of the existing clothes dryers use bimetallic strips to detect the conductivity of the clothes to realize the automatic drying judgment of the clothes, which are mainly composed of two metal strips on the drum supporting part, connecting wires and the humidity collection circuit of the computer board. This system collects the electrical conductivity between the bimetallic strips, substitutes it into the related sampling circuit of the computer board, and then judges the degree of dryness and wetness of the clothes through software calculation. This requires that the sampling circuit is stable and reliable, and the related devices have high precision. [0003] However, since the bimetallic strips of this dryer directly contact the clothes, when the cloth...
