Problems solved by technology

[0014] First, to detect the water level of the washing water, there is a water level detection means, that is, a pressure switch or a valve, which leads to an increase in product design and manufacturing costs.
[0015] Second, when the water supply volume of the washing water is set low, when the washing process occurs frequently, the washing water flows into the electric pump and the air flows in

Abstract

This invention relates to a dishwashing machine and its controlling method. The machine comprises water supply valve, washing motor of the driving washing pump and drainage valve. And it also comprises the detection element for washing motor and a controlling element to control the water supply interval and washing process when the electrical characteristics of the washing motor arrives at set time. The controlling method comprises the following: 1, After the user input washing start order, the machine performs as first set time and drives the motor; 2, to detect the electrical characteristics of washing motor; 3, The electricity characteristics value detected sustains the set value during the second set time and stops water supply and performs the washing process.

Description

technical field [0001] The present invention relates to a dishwasher. In particular, it relates to a dishwasher which optimizes the supply of washing water and its control method. Background technique [0002] Generally speaking, the dishwasher is a machine that washes the food residue stuck to the tableware after eating. like figure 1 As shown, the dishwasher is in the state where the tableware to be washed is placed on the shelf in the sink (illustrated symbols are omitted), and according to the control of the control unit 6, after the washing water of a predetermined water level is supplied through the water supply valve 3b, it is driven. A heater (not shown) heats the washing water. Then drive the washing motor 3a, start the washing pump, after the washing water is pumped by the washing pump (illustration omitted), it is sprayed to the tableware by the spray nozzle (illustration symbol omitted), and the food dregs stuck on the tableware are separated and washed. Then...
