Water inlet valve and washing machine

Abstract

The invention discloses a water inlet valve which comprises a valve. A water inlet and a water outlet are formed in the valve, a throttle channel is arranged in the valve, the water inlet and the water outlet can be communicated with each other via the throttle channel, and elastic elements for correspondingly adjusting the opening of the throttle channel along with pressure change of water flow at the water inlet are arranged at the throttle channel. The invention further discloses a washing machine with the water inlet valve. The water inlet valve and the washing machine have the advantagesthat the quantity of inlet water in water accommodating buckets of the washing machine can be controlled and regulated; the magnitude of the opening of the throttle channel can be adjusted by the aidof pressure difference of the water flow at the water inlet and water flow at the water outlet, accordingly, the water inlet valve and the washing machine have constant quantity of outlet water in a unit under total water pressures, water consumption of the washing machine can be reduced, and the washing efficiency can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of solenoid valves, and in particular relates to a water inlet valve, in particular to a washing machine equipped with the water inlet valve. Background technique [0002] The washing machine controls the on-off of the washing water by the water inlet valve, and some electromagnetic water valves cannot adjust the flow (such as image 3 As shown), this type of water inlet valve is greatly affected by the water outlet connecting pipeline and water supply pressure, and cannot achieve a constant water output per unit time; some water inlet valves are equipped with simple flow adjustment components inside the valve body (Such as Figure 4 As shown), the flow adjustment of the water inlet valve is usually realized by independent rubber parts or through the cooperation of rubber parts and plastic parts, and the adjustment of the water output is realized by changing the effective area of ​​the water inlet through th...

Problems solved by technology

[0002] The washing machine controls the on-off of the washing water by the water inlet valve, and some electromagnetic water valves cannot adjust the flow (such as image 3 As shown), this type of water inlet valve is greatly affected by the water outlet connecting pipeline and water supply pressure, and cannot achieve a constant water output per unit time; some water inlet valves are equipped with simple flow adjustment components inside the valve body (like Figure 4 As shown), the flow adjustment of the water inlet valve is usually realized by independent rubber parts or through the cooperation of rubber parts and plastic parts, and the adjustment of the water output is realized by changing the effective area of ​​the water inlet through the difference in pressure difference between the water inlet and the water outlet , however, the control method of this structure, on the one hand, is greatly affected by the rubber parts, and the hardness, thickness, elasticity of the rubber parts, and the characteristics of the rubber with temperature changes will have an indirect impact on the flow control. On the other hand, due to It may require the cooperation of plastic parts, the size of the plastic parts, and the assembly and cooperation with the rubber parts will also affect the flow control, so that this type of electromagnetic water valve cannot realize the unit under the condition of water pressure changes and different outlet pipeline connections. Stability of water output over time

Even this structure determines that the electromagnetic water valve using this structure cannot achieve constant water flow

[0003] Some washing machines control the water intake by controlling the time of the water inlet valve. If the accuracy of the water output per unit time of the water inlet valve cannot meet the requirements, the overall water intake will exceed the required range; Control the ratio of cold water and hot water intake to configure the washing water suitable for the temperature of clothes washing, and control the water intake per unit time of the cold water and hot water inlet valves directly affects the temperature of the washing water. At the same time, according to the whole machine Energy efficiency requirements, the amount of hot water intake, indirectly affect the energy consumption of the whole machine
