[0028] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] This embodiment provides a pump valve assembly that can be used in an electrical device, the electrical device includes an inner tank 200, specifically, the electrical device can be a steam oven, an integrated stove, etc. After use, the inner tank 200 is prone to oil stains, odors, etc., and the inner tank 200 needs to be cleaned. Figure 1 As shown, the pipeline system for cleaning the inner liner 200 in the electrical equipment includes a pump valve assembly 100, a cleaning component 300, etc., wherein the cleaning component 300 can be a nozzle or a spray head, the number of which can be determined according to the volume of the inner liner 200, and the installation of the nozzle or the spray head inside the inner liner 200 can be determined according to the specific electrical equipment, based on achieving better flushing of the inner liner 200. For example, the spray component can include a spray pipe, the spray pipe has at least one spray head, and the spray head is located inside the inner liner 200.

[0030] like Figure 1-Figure 4 As shown, the pump valve assembly includes a pump body 1, a valve component and a clamping part, wherein the pump body 1 is provided with an inlet connection part 11 and an outlet connection part 12, the valve component includes an inlet valve component 21 and an outlet valve component 22, the inlet valve component 21 and the outlet valve component 22 are both three-way valves, the clamping part includes two clamping parts 3, the two clamping parts 3 are respectively a first clamping part 33 and a second clamping part 34, the inlet connection part 11 and the inlet valve component 21 are limitedly connected by the first clamping part 33, and the outlet connection part 12 and the outlet valve component 22 are limitedly connected by the second clamping part 34.

[0031] The inlet valve component 21 and the outlet valve component 22 are respectively connected to the inlet connecting part 11 and the outlet connecting part 12 of the pump body 1 through the first clamping part 33 and the second clamping part 34, and the originally separately installed parts are integrated into a pump-valve assembly. The pump-valve assembly is subsequently used in the cleaning mode scenario, with a high degree of functional integration and relatively reduced installation space requirements.

[0032] The inlet valve component 21 and the inlet connection portion 11 are connected via the first joint 4 and the second joint 5. Specifically, the inlet valve component 21 may be provided with the first joint 4 and the inlet connection portion 11 may be provided with the second joint 5, or the inlet valve component 21 may be provided with the second joint 5 and the inlet connection portion 11 may be provided with the first joint 4. Similarly, one of the outlet valve component 22 and the outlet connection portion 12 may be provided with the first joint 4 and the other may be provided with the second joint 5, and the outlet valve component 22 and the outlet connection portion 12 may also be connected via the first joint 4 and the second joint 5.

[0033] like Figure 5-Figure 7As shown, the side wall of the first joint 4 is provided with a socket 41, the outer peripheral wall of the second joint 5 is provided with a slot 51, and the clamping member 3 includes a fixing rod 31. When the second joint 5 is inserted into the first joint 4, the socket 41 and the slot 51 are correspondingly connected, and the fixing rod 31 can be inserted into the socket 41 and the slot 51. Through the limiting effect between the fixing rod 31 and the inner wall of the socket 41 and the limiting effect between the fixing rod 31 and the groove wall of the slot 51, the first joint 4 and the second joint 5 can be limited to prevent the first joint 4 and the second joint 5 from being separated, thereby fixing the pump body 1 and the valve component.

[0034] For the convenience of explanation, the following description will be made by taking the example that the inlet connection part 11 and the outlet connection part 12 of the pump body 1 are provided with the first joint 4 and the inlet valve component 21 and the outlet valve component 22 of the valve component are provided with the second joint 5.

[0035] The first connector 4 and the second connector 5 are plug-connected and fixed by the clamp 3, so that the pump valve assembly can be installed in the electrical equipment as a whole, which simplifies the overall assembly operation of the electrical equipment, simplifies manual operation, improves assembly efficiency, and reduces costs. In addition, the pump body 1 and the valve component are directly connected and fixed, and there is no need to connect them through a pipeline, which can effectively reduce the overall volume of the pump valve assembly, reduce the requirements for installation space, and ensure the installation stability between the pump body 1 and the valve component. In addition, the fixing rod 31 is inserted into the socket 41 and the slot 51 to limit the separation of the first connector 4 and the second connector 5. The overall structure is simple and the fixing method is relatively simple, which is convenient for installation operation.

[0036] like Figure 5 and Figure 6 As shown, the first joint 4 is further provided with a positioning groove 72, and the second joint 5 is further provided with a positioning protrusion 71. When the first joint 4 is inserted into the second joint 5, as shown in FIG. Fig. 9 and Fig.10 As shown, the positioning protrusion 71 is located in the positioning groove 72, and the slot 51 is coaxially connected with the jack 41. By setting the positioning groove 72 and the positioning protrusion 71, the plug connection between the first connector 4 and the second connector 5 can be positioned, and the positioning protrusion 71 and the positioning groove 72 form mutually adapted positioning components. Of course, the first connector 4 can also be provided with the positioning protrusion 71, and the second connector 5 can be provided with the positioning groove 72.

[0037] Alternatively, in this embodiment, the outer wall of the first connector 4 and the outer wall of the second connector 5 may be provided with marking lines, and the marking lines may form a positioning component. When the first connector 4 and the second connector 5 are plugged in and connected, the marking lines of the two are aligned, and the slot 51 and the jack 41 may be coaxially connected. The positioning component formed by the positioning protrusion 71 and the positioning groove 72 can achieve a positioning effect, and can also limit the relative rotation of the first connector 4 and the second connector 5 after they are plugged in, thereby ensuring installation stability.

[0038] In this embodiment, a sealing member 61 is further provided between the first joint 4 and the second joint 5 along the circumferential direction to ensure the sealing between the first joint 4 and the second joint 5. Figure 8 As shown, the outer wall of the second joint 5 is also provided with a sealing groove 62 along the circumferential direction, and the sealing groove 62 is used to install the sealing member 61 to ensure the stability of the position of the sealing member 61 during the installation process. Alternatively, the inner circumferential wall of the second joint 5 may be provided with a sealing groove 62 along the circumferential direction for installing the sealing member 61, and no specific limitation is made here.

[0039] The side wall of the first joint 4 is respectively provided with two insertion holes 41 corresponding to each fixing rod 31, that is, when the first joint 4 and the second joint 5 are plugged, the fixing rod 31 can pass through one insertion hole 41, the slot 51 and another insertion hole 41 in sequence. Of course, the side wall of the first joint 4 can also be provided with one insertion hole 41 corresponding to each fixing rod 31, and the fixing rod 31 passing through the insertion hole 41 and the slot 51 can also limit the separation of the first joint 4 and the second joint 5. When the first joint 4 and each fixing rod 31 are provided with two insertion holes 41 correspondingly, the limiting stability of the fixing rod 31 and the two joints can be further improved.

[0040] like Figure 5 , Fig. 9 and Fig.10 As shown, the outer wall of the side wall of the first joint 4 is also fixed with an extension portion 42 corresponding to each plug hole 41, and the plug hole 41 is arranged through the extension portion 42. In this way, the axial length of the plug hole 41 can be extended. After the fixing rod 31 passes through the plug hole 41, the matching area between the fixing rod 31 and the plug hole 41 can be increased, thereby ensuring the structural stability. Specifically, the extension portion 42 and the side wall of the first joint 4 can be integrally formed, welded, or screwed, and no specific limitation is made here.

[0041] like Figure 7 As shown, the clamping member 3 includes the two above-mentioned fixing rods 31, and the clamping member 3 also includes a connecting rod 32, which is connected between the ends of the two fixing rods 31 to form a U-shaped structure. Correspondingly, the side wall of the first joint 4 is correspondingly provided with two groups of sockets 41, and each group of sockets 41 is respectively provided with two coaxially arranged sockets 41. When the first joint 4 and the second joint 5 are plugged in, the two fixing rods 31 can be inserted and fixed through a one-time operation, which ensures the stability of the overall structure while simplifying the installation operation.

[0042] The cross-sectional shapes of the first joint 4 and the second joint 5 are not limited, such as circular or square structures. When the cross-sectional shapes of the first joint 4 and the second joint 5 are both circular structures, the joint structure of the existing pump body 1 and the valve component is applicable, and the slot 51 can be arranged along the circumference of the second joint 5 (such as Figure 6 and Fig.10 As shown in the figure, such a configuration can simplify the processing technology of the slot 51, or the outer wall of the second joint 5 can also be provided with two slots 51 in parallel, and the two slots 51 correspond to the two fixing rods 31 respectively. Such a configuration can increase the contact area between the fixing rod 31 and the slot 51 wall, and further ensure the fixing stability. When the cross-sectional shape of the first joint 4 and the second joint 5 is a square structure, the slots 51 can be correspondingly provided on the two opposite sides of the square structure.

[0043] The electrical device also includes a return pipe 91, a clean water pipe 92, a water inlet pipe 93 and a water outlet pipe 94. The inlet valve component 21 and the outlet valve component 22 are both electric three-way valves, specifically including three connecting ends 23, one of which is provided with a second connector 5. The other two connecting ends 23 of the inlet valve component 21 are also connected to the clean water pipe 92 and the return water pipe 91 respectively, and the other two connecting ends 23 of the outlet valve component 22 are connected to the inlet pipe 93 and the outlet pipe 94 respectively. When the inner tank 200 needs to be cleaned, the outlet valve component 22 opens the inlet pipe 93 and closes the outlet pipe 94. When the cleaning liquid needs to be discharged, the outlet valve component 22 opens the outlet pipe 94 and closes the inlet pipe 93.

[0044] The cleaning mechanism also includes a clean water tank 400 and a return water tank 500, wherein the clean water tank 400 is connected to the clean water pipe 92 and is used to provide clean water (cleaning liquid). The clean water can enter the cleaning component 300 along the water inlet pipe 93 under the power provided by the pump body 1, and clean the inner tank 200. The return water tank 500 is connected between the water outlet 201 of the inner tank 200 and the return water pipe 91. The water after cleaning the inner tank 200 can be passed into the return water tank 500, and along the return water pipe 91, under the power of the pump body 1, it can enter the cleaning component 300 along the water inlet pipe 93 again, and clean the inner tank 200.

[0045] When the inner tank 200 needs to be cleaned with clean water, the inlet valve component 21 opens the clean water pipe 92 and closes the return water pipe 91. When the inner tank 200 needs to be circulated and cleaned with water in the return water tank 500 or the cleaning liquid needs to be discharged, the inlet valve component 21 opens the return water pipe 91 and closes the clean water pipe 92.

[0046] In the process of cleaning the inner tank 200 and in the process of discharging the cleaning liquid, the pump body 1 provides power, and the cleaning liquid is poured into the inner tank 200 without manual operation, which has a high degree of automation, reduces manual operation, reduces costs, and improves cleaning efficiency. Specifically, the pump body 1 can be a centrifugal pump or a DC pump.

[0047] When the number of valve components is only one, the valve component can be the inlet valve component 21 or the outlet valve component 22 (eg, Figure 4 Any of the above may be used, and no specific limitation is made herein.

[0048] The pump body 1 also includes an inner cavity connected between the inlet connection part 11 and the outlet connection part 12, and the inner cavity is mainly used to set the movable parts for pumping the cleaning liquid. The movable parts can be rotating parts such as blades or impellers, and of course, they can also be other parts such as plungers. The pump valve assembly 100 also includes a heating part 8 fixed to the pump body 1. Before the cleaning liquid is passed into the inner tank 200, it is first heated by the heating part 8, which can improve the cleaning effect of the inner tank 200. In addition, integrating the heating part 8 into the pump body 1 can improve the integration of the pump valve assembly and further reduce subsequent installation operations.

[0049] The heating part 8 and the pump body 1 can be connected in a limited position by means of clamps, riveting, encapsulation fixation or welding. The clamp connection is convenient for disassembly and maintenance, the rivet connection has higher fixation reliability, and the encapsulation fixation can provide a better working environment for the heating part 8 and increase the service life of the heating part 8.

[0050] The heating part 8 is arranged on the inner cavity wall between the inlet connection part 11 and the outlet connection part 12 of the pump body 1. This arrangement is conducive to better heating of the cleaning liquid and improving the efficiency of cleaning the inner tank 200. Specifically, the heating part 8 may include a heating tube, which is wound around the outer wall of the inner cavity and is specifically arranged on the side facing the inlet connection part 11. The heating tube has a simple structure and is relatively easy to install.

[0051] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
