Problems solved by technology

[0015] Since it is impossible to judge whether the driving part of the drainage pump used to drive the drainage pump is faulty, the water level sensor can only be used to judge whether the drainage is normal.
[0016] In addition, since the dishwasher system control device cannot determine whether the drain pump overflows, it cannot accurately determine whether the dishwasher is in a normal working state.

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 sensor signal of transmitter sends start command to the discharge pump to judge if the washer is normal and if the driver has accidence. The invention can judge normal state or accidence of washer based on the signal received by microprocessor, and if there is overflow accidence.

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...
