Washing machine timer and double drum washing machine using said timer

Abstract

The washing machine timer includes one first timing cam and its first reed contact circuit and one second timing cam and its first reed contact circuit, and these two cams are combined to the same axis. These two cams has their contour projection along the said axis constituting four closed loop distributed areas, including the first stopping area, the first timing operation area, the second stopping area and the second timing operation area. The double tub washing machine with the said timer has its power supply to power the dewatering motor via the first reed contact circuit and power the washing motor via the second reed contact circuit, timing cam shaft coupled to the main shaft, and operation panel with four sector control indications, including the first stopping area, the dewatering timing operation area, the second stopping area and the washing timing operation area. The present invention has one timer for both wash timing and dewatering timing, simple structure, easy installation and low cost.

Description

Technical field [0001] The invention relates to a washing machine timer and a double-tub washing machine. Background technique [0002] At present, two-tub washing machines usually use two timers with only one timed step—a washing timer and a dehydration timer to control the washing and dehydration timing functions, respectively. Such a timer cannot be simplified to an appropriate timer with two timed steps, so as to simplify the structure of the double-tub washing machine and facilitate installation, thereby reducing costs. The prior art has disclosed a timer with two timed steps, which can be found in the Chinese Utility Model Patent Specification CN2443478Y "Washing Timer with Soaking Function". There is no interruption section that stops all running between the two timing steps of the timer, which needs to be changed after the user's operation, so that the user can choose to enable the second timing step or re-enable the first timing step or just that. termination. Therefore,...

AI Technical Summary

Problems solved by technology

Therefore, the timer continues to run after the first timing step is completed and automatically enters the second timing step. It is not suitable for double-tub washing machines as two functions of laundry timing and dehydration timing.
