Problems solved by technology
When the washing machine is powered on, the relay controls the water inlet valve to start water intake. However, when the solid state relay controlling the water inlet valve fails, water will always enter the water inlet channel. When the water intake reaches a certain level, it will flow from the washer Overflow in the barrel, resulting in overflow

Embodiment 1
[0047] figure 1 It is a flow chart of the water inlet valve control method of the washing machine provided in Embodiment 1 of the present invention.
[0048] refer to figure 1 , the execution subject is the control unit, and the method includes the following steps:
[0049] Step S101, detecting the level state of the relay;
[0050] Step S102, when the level of the relay is the first level, receive the first prompt information sent by the flowmeter;
[0051] Specifically, the relay is used to control the water inlet valve, therefore, by detecting the state of the relay, the state of the water inlet valve can be determined. When the relay is at the first level, that is, the relay is not closed, and the water inlet valve is not turned on; when the relay is at the second level, that is, the relay is closed, and the water inlet valve is turned on.
[0052] When the relay is at the first level, the flowmeter starts to detect whether there is water flow passing through. If there...

The embodiment of the invention relates to the technical field of intelligent household electrical appliances, in particular to a water inlet valve control method and device of a washing machine and an intelligent household electrical appliance. The water inlet valve control method comprises the steps that a control unit detects a level state of a relay, water enters a water inlet channel when itis detected that the level state of the relay is in a first level state, a flowmeter detects water flow at the moment and then sends first prompting information to the control unit, the control unit controls a throttling device to be in an actuation state according to the first prompting information, and accordingly the overflow phenomenon is avoided. The first level is low level, and the first prompting information is the information about that water flows through the water inlet channel and flows into the flowmeter.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of smart home appliances, in particular to a method and device for controlling a water inlet valve of a washing machine, and smart home appliances. Background technique [0002] Currently, washing machine water intake is controlled by solid state relays. When the washing machine is powered on, the relay controls the water inlet valve to start water intake. However, when the solid state relay controlling the water inlet valve fails, water will always enter the water inlet channel. When the water intake reaches a certain level, it will flow from the washer The barrel overflows, resulting in an overflow situation. Contents of the invention [0003] In order to solve the above-mentioned technical problems or at least partly solve the above-mentioned technical problems, embodiments of the present invention provide a water inlet valve control method and device for a washing machine, an...
