Problems solved by technology

[0014] However, the existing common dishwashers with the above-mentioned structure have the following disadvantages: when overflow is sensed, it is impossible to judge whether the element transmitting the sense signal is faulty or not.
Therefore, even if an overflow phenomenon actually occurs, it may be due to the failure of the component transmitting the sensory signal, and the dishwasher cannot accurately judge it.

Abstract

The invention relates to a bowl washer and relative control method. Wherein, it comprises water discharge pump, power, sensor, pump driver, transmitter and microprocessor; the sensor senses the overflow in water supply; transmitter based on the states of sensor and driver transmits information; the microprocessor based on the control of user program reads the information of transmitter to judge the accidence of transmitter or normal state, to output control signal. The invention can judge normal state or accidence of photoelectric sensor based on the signal received by microprocessor, to stabilize washing operation.

Description

technical field [0001] The invention relates to a dishwasher and a control method thereof. Background technique [0002] As we all know, a dishwasher is a device that can automatically clean food residues and dirt on tableware. [0003] As shown in FIG. 1 , a washing tub 1 is formed inside the existing common dishwasher, and an upper rack 10 and a lower rack 11 for placing tableware are arranged in the washing tub 1 . [0004] An upper spray arm 8 and a lower spray arm 9 for spraying washing water are arranged under the upper shelf 10 and the lower shelf 11 respectively. [0005] The bottom of the washing tub 1 is provided with a water tank 3 for storing washing water, and a filter 2 for filtering the washing water is arranged in the water tank 3 . [0006] In addition, a heater (not shown in the figure) for heating the washing water is also arranged below the washing tub 1 . [0007] One side of the water tank 3 is provided with a circulation pump 5 for circulating washi...
