Device and technology for solving short circuit of washing machine while maintaining normal operation

Abstract

The invention provides a device and technology for solving a short circuit of a washing machine while maintaining the normal operation. The on-off control signal output end of an internal control circuit of a washing machine alternating current four-wire solid-state switch is connected to a light emitting module, the on-off control signal input end of an internal control circuit of each controlledalternating current four-wire solid-state switch is connected to the corresponding photoconductive device, on-off control signals output by the master control washing machine alternating current four-wire solid-state switch can be transmitted to each controlled alternating current four-wire solid-state switch at the same time through the light emitting module, a respective light path transmissiondevice and the photoconductive device, and the united and consistent on-off action of all alternating current four-wire solid-state switches is achieved. The switch is different from common contact switches and externally provided with four leads, and when two of the leads are short-circuited, the other two leads are switched to enable the washing machine to continue to operate normally.

Description

[0001] 1. Technical field [0002] The invention relates to the design field of washing machines, and proposes a device and technology for solving the short circuit of the washing machine and still working normally. [0003] 2. Background technology [0004] The invention and use of electricity has brought great changes to people's production and life. The widespread use of electricity has driven lasting and profound structural changes in production. Electricity gradually replaced steam. In the 1870s, as new electricity entered the production field as a new energy source, it became the main power of factory machines, and human history entered the "Electrical Age". Due to the use of electricity, other industrial sectors have also developed rapidly, especially the development of the steel industry, which has made mankind bid farewell to the "cotton era" in the field of materials. Electrification and the advent of the "Steel Age" marked the rise of modern industry. The electri...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects of the above-mentioned existing washing machine design, and provide a method to solve the safety problems such as electric shock casualties and fires caused by the surge current generated when the wires of the washing machine are short-circuited, so as to solve the short-circuit hazard of the washing machine and ensure its circuit safety. And it can realize that the washing machine continues to work normally through the two wires at the other end when a short circuit occurs
