[0002] At present, the drain valves used in drain equipment such as dishwashers on the market that involve drainage, as Figure 1 shown, include a housing 1, an outer barrel bottom interface 11 connecting to the drain hole at the lower side of the outer barrel of the drain equipment, a drain port 12 connecting to the drain pipe for discharging the washing water to the outside of the drain equipment, and a valve chamber 13 located between the outer barrel bottom interface 11 and the drain port 12. There is an opening on one side of the valve chamber 13, and a valve plug 14 is installed in the valve chamber 13 through the opening. The valve plug 14 cuts off the passage between the outer barrel bottom interface 11 and the drain port 12. When drainage is required, the control motor pulls the valve plug 14 to open the passage between the outer barrel bottom interface 11 and the drain port 12, thereby realizing the drainage function.

[0003] However, the existing such drain valve only has the drainage function, with single function and low versatility. Summary of the Invention

[0004] The present application provides a multi-functional valve to solve the technical problems of the existing drain valve with single function and low versatility.

[0005] To solve the above technical problems, the present application adopts the following technical solutions to be realized:

[0006] A multi-functional valve is proposed, including a valve housing. The valve housing is provided with a first water inlet and a drain port. The cavity between the first water inlet and the drain port is defined as a valve chamber. There is a valve plug inlet on one side of the valve chamber; a valve plug is installed in the valve chamber; the valve housing is also provided with a multi-functional interface; and when the multi-functional valve is applied to a drain equipment, the opening position of the multi-functional interface is higher than the opening position of the drain port.

[0007] Further, a second water inlet is also provided on the valve housing.

[0008] Further, the opening direction of the multi-functional interface is different from that of the drain port.

[0009] Further, the opening direction of the multi-functional interface is different from that of the first water inlet.

[0010] Further, the opening direction of the second water inlet is different from that of the first water inlet.

[0011] Further, the multi-functional interface and the second water inlet are provided at the same height.

[0012] Further, the valve plug includes a telescopic valve plug body, a valve tube, a tension spring, a compression spring, a valve cover and a pull rod; the telescopic valve plug body is disposed in the valve chamber, the valve cover is fixed to the valve plug inlet, and one end of the telescopic valve plug body is fixed to the inner side of the valve cover in the valve chamber; a valve tube outlet is opened at the center of the valve cover, the valve tube is disposed inside the telescopic valve plug body, one end is connected to the end of the telescopic valve plug body, and the other end extends out of the valve housing through the valve tube outlet; the compression spring is disposed outside the valve tube inside the telescopic valve plug body; the tension spring is disposed inside the valve tube, one end is fixedly connected to the inside of the valve tube, and the other end is connected to the pull rod.

[0013] Compared with the prior art, the advantages and positive effects of the present application are as follows: The multi-functional valve proposed in the present application, in addition to including a first water inlet and a drain outlet, further includes a multi-functional interface, so that the multi-functional valve is not only used for the drainage function, but also can realize other functions of the drainage device based on the multi-functional interface. For example, when applied to a dishwasher, in addition to the basic drainage function, after connecting an air inlet device to the multi-functional interface, based on the passage between the first water inlet and the multi-functional interface, and based on the connection between the first water inlet and the inner cavity of the dishwasher, the purpose of blowing air to dry the inner cavity of the dishwasher can be achieved, saving the application of a separate ventilation valve for the dishwasher.

[0014] After reading the detailed description of the embodiments of the present application in conjunction with the drawings, other features and advantages of the present application will become clearer. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 is a schematic structural diagram of the multi-functional valve proposed in the present application;

[0017] Figure 3 is a schematic structural diagram of the multi-functional valve proposed in the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes in detail the specific embodiments of the present application in conjunction with the drawings.

[0019] The multi-functional valve proposed in the present application, as Figure 2 shown, includes a valve housing 2. The valve housing 2 is provided with a first water inlet 21 and a drain outlet 22. The cavity between the first water inlet 21 and the drain outlet 22 is defined as a valve chamber 23. A valve plug inlet 24 is opened on one side of the valve chamber 23; a valve plug is installed in the valve chamber 23.

[0020] The valve housing 2 of the multi-functional valve is also provided with a multi-functional interface 25; and when the multi-functional valve is applied to a drainage device, the opening position of the multi-functional interface 25 is higher than the opening position of the drain port 22; as Figure 2 shown in the installation application, the first water inlet 21 is opened upward, the drain port 22 is opened downward, and the multi-functional interface 25 is opened at a position between the first water inlet 21 and the drain port 22, higher than the drain port 22. The starting point of such a design is to achieve the water sealing effect and prevent water accumulation.

[0021] When the multi-functional valve is applied to a drainage device to achieve the drainage function, it can also simultaneously achieve other functions based on the multi-functional interface 25. For example, when applied to a dishwasher, in addition to the basic drainage function, after connecting an air inlet device to the multi-functional interface, based on the passage between the first water inlet and the multi-functional interface, and based on the connection between the first water inlet and the inner barrel of the dishwasher, the purpose of blowing air to dry the inner barrel of the dishwasher can be achieved, eliminating the application of a separate ventilation valve for the dishwasher. Using a single multi-functional valve to achieve multiple functions of a drainage device improves the versatility of the valve and solves the technical problems of the existing drainage valve with a single function and low versatility.

[0022] Specifically, the opening direction of the multi-functional interface 25 is different from that of the drain port 22, and the opening direction of the multi-functional interface 25 is also different from that of the first water inlet 21. When the valve chamber 23 is tubular, the opening directions of the multi-functional interface 25, the first water inlet 21, and the drain port 22 along the outer wall of the tubular valve chamber are all different.

[0023] As Figure 2 shown, the valve housing 2 of the multi-functional valve is also provided with a second water inlet 26 for other functions to improve the versatility of the multi-functional valve; the opening direction of the second water inlet 26 is different from that of the first water inlet 21; the multi-functional interface 25 and the second water inlet 26 are opened at the same height.

[0024] As Figure 2 shown, the valve plug includes a telescopic valve plug body 31, a valve tube 32, a tension spring 33, a compression spring 34, a valve cover 35, and a pull rod 36; the telescopic valve plug body 31 is placed inside the valve chamber 23, and the valve cover 35 is fixed to the valve

[0025] entrance 24, and one end of the telescopic valve plug body 31 is fixed inside the valve cover 35 in the valve chamber 23; a valve tube outlet is opened at the center of the valve cover 35, the valve tube 32 is placed inside the telescopic valve plug body 31, one end is connected to the end of the telescopic valve plug body 31, and the other end extends out of the valve housing 2 through the valve tube outlet; the compression spring 34 is placed outside the valve tube 32 inside the telescopic valve plug body 31, the tension spring 33 is placed inside the valve tube 32, one end is fixedly connected to the inside of the valve tube 32, and the other end is connected to the pull rod 36, and the pull rod 36 is connected to the motor.

[0026] Taking the application of this multi-functional valve in a dishwasher as an example, the multi-functional valve is installed at the bottom of the dishwasher. The first water inlet is connected to the washing water discharge outlet of the dishwasher, the drain outlet is connected to the inlet of the drain pipe, and the multi-functional interface is connected to the ozone outlet of the ozone module. When the dishwasher is washing, the telescopic valve plug body blocks the passage between the first water inlet and the drain outlet. When drainage is required after the washing program ends, the motor is controlled to work to drive the pull rod, the pull rod drives the tension spring to stretch, the tension spring drives the valve tube to move, and the valve tube drives the compression spring and the telescopic valve plug body to compress, thereby opening the passage between the first water inlet and the drain outlet, realizing the drainage function; after drainage ends, the motor stops working, the compression spring rebounds to drive the valve tube to move in the reverse direction, the valve tube drives the tension spring and the telescopic valve plug body to move in the reverse direction, and the tension spring drives the pull rod to reset, realizing the blocking of the passage between the first water inlet and the drain outlet.

[0027] When ozone release is required to achieve the sterilization and disinfection function, the multi-functional valve is closed, and the ozone generated by the ozone module passes through the passage between the multi-functional interface and the first water inlet. Based on the connection between the first water inlet and the inner cavity of the dishwasher, the ozone is transported into the inner cavity of the dishwasher to sterilize and disinfect the utensils such as bowls and dishes in the inner cavity of the dishwasher.

[0028] In practical applications, the air outlet of the drying module can also be connected to the second water inlet. When drying of the utensils inside the dishwasher is required, the multi-functional valve is closed, and the hot air generated by the drying module passes through the passage between the second water inlet and the first water inlet. Based on the connection between the first water inlet and the inner cavity of the dishwasher, the hot air is transported into the inner cavity of the dishwasher to realize the drying function of the utensils in the inner cavity of the dishwasher.

[0029] The above-mentioned multi-functional valve proposed in this application, in addition to including the first water inlet and the drain outlet, also includes a multi-functional interface and a second water inlet, enabling the multi-functional valve not only to be used for the drainage function, but also to realize other functions of drainage equipment such as dishwashers based on the multi-functional interface and the second water inlet, such as ozone sterilization, ventilation and drying, etc. It eliminates the application of multiple valves separately set for each function in drainage equipment such as dishwashers, realizes the valve application of multiple functions of drainage equipment with one multi-functional valve, improves the versatility of the valve, and solves the technical problems of the existing drain valve having a single function and low versatility.

[0030] It should be noted that the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
