Embodiment Construction

[0043] 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.

[0044] 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 discloses a noise control method and system for an electromagnetic valve and an air conditioner, relates to the field of noise reduction control of air conditioner electromagnetic valves and aim at solving the problem that when a current air conditioner switch component is switched off or switched on, great noise is generated, and use of a user is affected. The critical voltage duty ratio of the electromagnetic force in the electromagnetic valve is detected when the balance state of a metal bolt is maintained; whether a switch controller sends switching-off or switching-on signals to the electromagnetic valve or not is detected; and the duty ratio of the control signals in the switching-off or switching-on process of the electromagnetic valve is adjusted in a segmented manner according to the critical voltage duty ratio. According to the noise control method and system for the electromagnetic valve and the air conditioner, the duty ratio of the control signals is adjusted in the switching-on and switching-off processes of the electromagnetic valve so that the jumping changing type of currents in an electromagnetic valve coil is transformed into a gradually and gently changing type, and therefore the electromagnetic force can be gently changed, impulsion is reduced, and the sounds generated by collisions are effectively lowered.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to the field of noise reduction control of a water drain switch for an air conditioner water tank. 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 store...
