Embodiment Construction

[0041] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0042] The sink drain switch is an on-off mechanism controlled by a solenoid valve, and its internal structure is that a movable metal bolt is arranged at the switch, one end of the metal bolt is soft plastic, and the other end is a spring. The battery valve coil is sleeved on one end of the circular slide tube, and the metal bolt is movable in the slide tube. Under normal conditions, the coil of the solenoid valve is not energized, and the spring bears against the metal bolt so that it is located at the non-solenoid valve end of the slide pipe, blocking the water pipeline. When the water needs to be released, the coil is energized to generate a magnetic force, which overcomes the compression force of the spring to ...

Abstract

The invention provides an electromagnetic valve switch control method and system and an air conditioner, and relates to the field of air conditioner electromagnetic valve switch control. The electromagnetic valve switch control method aims at solving the problem that customer use is affected due to the fact that existing air conditioner switch components produce large noises when turned off or turned on. The electromagnetic valve switch control method comprises the steps that whether an on-off controller sends a turn-off or turn-on signal to an electromagnetic valve switch or not is detected, and when the turn-off or turn-on signal is detected, the current of an electromagnetic coil in the on-off process of the electromagnetic valve switch is controlled by adjusting the voltage to produce gradual gentle or segmented step type changes. The specific implementation mode of the electromagnetic valve switch control method comprises the step that the duty ratio of a control signal in the turn-off or turn-on process of the electromagnetic valve switch is adjusted, and then the current of the electromagnetic coil is adjusted. According to the electromagnetic valve switch control method and system and the air conditioner, the duty ratio of the control signal in the on-off process of the electromagnetic valve switch is adjusted, so that the change mode of the current in the electromagnetic valve coil is converted from hopping to gradual gentle, the electromagnetic force can be changed gently, the impulsive force magnitude is reduced, and noises caused by collision are effectively reduced.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to the field of air conditioner electromagnetic valve switch control. Background technique [0002] With the improvement of the quality of life, users have more and more detailed requirements on the function and quality of air-conditioning products. The cleaning of the dust filter has always been a function that has attracted much attention. New air conditioner products are gradually introducing more intelligent cleaning methods, including regular cleaning, automatic cleaning, etc. The cleaning method has also changed from dry brushing to wet brushing with better results. Due to the improvement of the automation of functions, some equipment will inevitably be added, and the water discharge switch of the water storage tank when wet brushing is one of them. After the wet brushing function is activated, the switch is closed and the water tank is stored. After the water washing i...
