Problems solved by technology

However, the higher the rotation speed of the washing motor, the greater the loss of the corresponding motor drive circuit, the higher the heat generation and the higher the temperature rise; in addition, if the washing motor runs abnormally due to excessive load, the It will cause the current of the motor drive circuit to increase, thereby increasing the temperature of the motor drive circuit, which in turn will cause the temperature of the components to be damaged due to a sharp rise
Therefore, the washing method of

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] figure 1 It shows the implementation process of the washing control method of the dishwasher provided by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0021] In step S1, during the washing process of the dishwasher, the washing motor in the dishwasher is controlled by the motor drive circuit to alternately switch between high and low speeds; the high speed running time of the washing motor is shorter than the low speed running time.

[0022] Among the...

Abstract

The invention belongs to the technical field of dish-washing machine control, and provides a dish-washing machine and a washing control method and system for the same. During a dish washing process conducted by the dish-washing machine, a washing motor runs in a high-speed and low-speed alternate switch mode controlled by a motor drive circuit, the dish cleaning effect can be improved during high speed running of the washing motor, and an average working current of the washing motor can be reduced through the high-speed and low-speed switch at the same time, so that non standard-exceeding of temperature rise of the motor drive circuit is guaranteed; meanwhile, the working current of the washing motor is subjected to successive detection according to preset detection times, the normal times of the motor current are subjected to superposition counting if overflowing does not occur in the working current of the washing motor; after the completion of the detection, if it is concluded that overload running occurs in the washing motor according to the normal times of the motor current and the preset detection times, the motor drive circuit is controlled to stop working, so that overloading of the washing motor is accurately judged and the motor drive circuit is timely shut off to avoid the component damage due to the temperature rise.

Description

technical field [0001] The invention belongs to the technical field of dishwasher control, and in particular relates to a dishwasher and a washing control method and system thereof. Background technique [0002] At present, when the existing dishwashers wash the tableware, the washing method adopted is to pump water from the inner tank to the spray arm through the washing motor at a certain speed, and then wash it with the water column sprayed out of the spray arm. tableware. Because the flow velocity and pressure of the water column sprayed out by the spray arm depend on the rotation speed of the washing motor, the greater the rotation speed of the washing motor, the faster the flow velocity and the greater the pressure of the water column, and the better the washing effect of the tableware. However, the higher the rotation speed of the washing motor, the greater the loss of the corresponding motor drive circuit, the higher the heat generation and the higher the temperatur...
