[0001] The utility model relates to the technical field of solenoid valves, in particular to a solenoid valve with an integrated switching mode. Background Art

[0002] In the prior art, the functional requirements for home appliances are diversified, and washing machines are an obvious example. In addition to the basic functions of washing and dehydrating clothes, people now also require washing machines to have drying functions, automatic feeding functions, sterilization and disinfection functions, upper and lower barrels, and even sweeping robots, etc.

[0003] Faced with the current situation of diversified functions of washing machines, the water inlet solenoid valve also needs to be upgraded accordingly. Now different models of washing machines are equipped with different types of multi-cavity solenoid valves, or are equipped with 2 or more solenoid valves, and there is also a multi-cavity solenoid valve with a reversing valve. However, this will make the pipes and circuits in the washing machine box more complicated, and will also take up a lot of space in the box. Finding the fault point is also a major difficulty. Therefore, how to combine the reversing valve and the water inlet valve into one, and make the pipe direction and circuit layout in the box more reasonable and standardized, so that customers can have more diversified selection of water inlet solenoid valves with complex functions in the early stage of design. Summary of the invention

[0004] Therefore, the purpose of the utility model is to provide a solenoid valve with an integrated switching mode. Through the mutual cooperation of the solenoid valve assembly and the reversing assembly, when in use, the water inlet solenoid valve is combined with the reversing valve, and the same water path of the water inlet solenoid valve is derived into two paths, which can be switched according to the needs of the washing machine to meet the water demand of different parts.

[0005] To solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a solenoid valve with integrated switching mode, comprising:

[0006] A solenoid valve assembly, the solenoid valve assembly comprising a water inlet solenoid valve, a first connecting plate connected to the water inlet solenoid valve, a first screw hole opened on the surface of the first connecting plate and connected to the internal thread of the water inlet solenoid valve, and opened on the surface of the first connecting plate;

[0007] A reversing assembly, the reversing assembly includes a reversing valve arranged on the side of the water inlet solenoid valve, a second connecting plate connected to the reversing valve, a threaded pipe connected to the second connecting plate, a second screw hole opened on the surface of the second connecting plate, and a screw passing through the second screw hole.

[0008] As a preferred solution of the integrated switching solenoid valve described in the utility model, the solenoid valve assembly further includes a groove provided on the first connecting flat plate frame;

[0009] There are two grooves, which are distributed at an angle of 180 degrees.

[0010] As a preferred solution of the electromagnetic valve with integrated switching mode described in the utility model, the reversing component also includes an annular groove opened on the surface of the threaded tube and an O-ring inserted into the annular groove.

[0012] There are two protrusions, which are distributed at an angle of 180 degrees.

[0013] As a preferred solution of the electromagnetic valve with integrated switching mode described in the utility model, the distributed protrusions and grooves are engaged with each other.

[0014] As a preferred solution of the integrated switching solenoid valve described in the utility model, the threaded pipe is threadedly connected to the internal thread, and the O-ring is inserted into the internal thread.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1. The utility model cooperates with the solenoid valve assembly and the reversing assembly to achieve the combination of the water inlet solenoid valve and the reversing valve during use, so that the same water path of the water inlet solenoid valve is derived into two paths, which can be switched according to the needs of the washing machine to meet the water demand of different parts.

[0017] 2. Based on the first beneficial effect, the solenoid valve and the reversing valve are limited by setting the protrusions and grooves after connection to ensure that the coils of the two valves are in the same horizontal direction when the two valves are finally assembled. The protrusions and grooves are designed to be inclined so that when the threaded pipe is connected to the internal thread, the protrusions can be smoothly rotated and stuck in the grooves.

[0018] During specific use, the user rotates the reversing valve, and the reversing valve drives the threaded tube to progress in the internal thread until the convex point and the groove are connected to each other and limited. At this time, the O-ring is completely inserted into the internal thread to seal and prevent water leakage, and the first connecting plate and the second connecting plate fit each other. At this time, screws are used to penetrate the first screw hole and the second screw hole in sequence to lock the first connecting plate and the second connecting plate. The convex point and the groove are inclined, so that when the threaded tube is connected to the internal thread, the convex point can be smoothly rotated and stuck in the groove, ensuring that the coils of the two valves are in the same horizontal direction when the two valves are finally assembled.
