Description

Technical Field

[0001] This invention relates to the field of valve technology, specifically to an integrated valve for both clean water and wastewater. Background Technology

[0002] As living standards improve, people's demands for quality of life and environmental hygiene are also increasing, requiring appliances that can intelligently distinguish between clean and wastewater to meet daily needs. However, traditional home appliances on the market either lack the function of distinguishing between clean and wastewater, or, even if they do, their corresponding size increases, making them unsuitable for the installation space of small appliances.

[0003] To address this, Chinese utility model patent CN217709991U provides a switching device, comprising: a first valve body having a first inlet and a first outlet, and an internally disposed first valve plug for controlling the on / off state between the first inlet and the first outlet; a second valve body having a second inlet and a second outlet, and an internally disposed second valve plug for controlling the on / off state between the second inlet and the second outlet; further comprising a driving member and a transmission mechanism, wherein the driving member generates movement in a first direction, which drives the first valve plug to move via the transmission mechanism; the driving member generates movement in a second direction opposite to the first direction, which drives the second valve plug to move via the transmission mechanism. This solution allows selective control of the on / off state between the inlet and outlet of either the first or second valve body by changing the direction of movement of the driving member.

[0004] However, the above technical solution has the following drawbacks:

[0005] (1) The valve body is set horizontally, and the inlet and outlet of the valve body are set on the side of the valve body. During use, when the water pressure is too low, the flow rate of the valve body is small, which affects the normal use of the washing equipment.

[0006] (2) The second inlet of the second valve body is connected to the drain port. Impurities such as lint are easily left in the second valve body, which can easily block the normal drainage of the second valve body and thus affect its service life.

[0007] In view of this, there is an urgent need to improve the structure of the existing water and sewage valves in order to avoid the water and sewage valves from failing to work properly due to low water pressure or being blocked by impurities and affecting sewage discharge.

Initially, the motor shaft of the water valve motor 3 rotates 90° counterclockwise, opening water outlet 2# while water outlet 1# remains closed. Then, the motor shaft rotates 180° counterclockwise, opening water outlet 1# and closing water outlet 2#. Next, the motor shaft rotates 270° counterclockwise, returning to the starting position. The control touch part 711 of the control board 71 contacts the contact surface of the tactile switch 73, receiving a position signal. At this time, all water outlets of the water valve close.

[0089] The ball valve stem 42 and ball valve core 41 can rotate within the cavity driven by the sewage valve motor 5. Based on the given signal, the motor shaft of the sewage valve motor 5 drives the ball valve stem 42 and ball valve core 41 to rotate, completing the opening and closing of the sewage valve. Initially, the motor shaft rotates 90° counterclockwise, opening the sewage outlet 135. Then, the motor shaft rotates 90° clockwise, returning to the starting position. The control touch part 711 of the control board 71 contacts the contact surface of the tactile switch 73, receiving a position signal. At this time, the sewage valve outlet closes.

[0090] Compared with the prior art, the integrated clean water and wastewater valve provided by the present invention has the following advantages:

[0091] (1) The clear water chamber and the sewage chamber are both set on the valve seat. The clear water valve assembly and the sewage valve assembly are set inside the valve seat, which improves the structural strength of the integrated clear water and sewage valve, while reducing the volume of the clear water valve and the sewage valve, simplifying the complexity of the water circuit layout inside the machine, and reducing the difficulty of installation and maintenance of the clear water valve and the sewage valve inside the machine.

[0092] (2) The sewage valve adopts a ball valve. When the valve core is fully open, the cross-sectional area of ​​the valve core channel is the same as the inlet and outlet area of ​​the sewage valve. This can ensure that the sewage valve does not get lint when it is fully open, thereby avoiding lint and other impurities from clogging and affecting the service life of the sewage valve.

[0093] (3) The sewage valve adopts the ball valve method, and the clean water valve adopts the method of water inlet at the top and water outlet at the bottom. The sewage valve and the clean water valve do not have high requirements for water inlet pressure. They can achieve low water pressure and large flow when open, thereby avoiding the problem of home appliances not being able to be used normally due to low water pressure and small flow.

[0094] (4) The water valve has one inlet and two outlets to meet the user's requirements for water discharge from the water valve in different functional modes of the equipment; the two outlets on the water valve are separated by a partition and sealed by the outlet sealing component to effectively prevent water leakage from the water valve; the water valve switching plate and the water valve plate are made of ceramic material, which can ensure the sealing performance during use and prevent water leakage, further improving the sealing performance of the water valve.

[0095] (5) Both the clean water valve and the sewage valve are equipped with a tactile switch. The tactile switch is located on the side of the motor. It can be turned on again in case of a sudden power failure during use. It can automatically find the zero position according to the program and automatically close, ensuring the reliability during use.

[0096] This invention is not limited to the above-described preferred embodiments. Anyone should know that any structural changes made under the guidance of this invention, and any technical solutions that are the same as or similar to this invention, fall within the protection scope of this invention.
