Description

Technical Field

[0001] This utility model relates to the field of water inlet valve technology, specifically to an installation structure for a water inlet valve in a household appliance. Background Technology

[0002] Household appliances (such as washing machines) are equipped with water inlet valves. The installation of these valves requires an installation structure. A patent with authorization announcement number CN213113976U, entitled "An Installation Structure for a Washing Machine Water Inlet Valve," includes a snap-fit ​​component, a snap-fit ​​groove, and a mounting hole. The snap-fit ​​component has an end cap at its rear end and at least two separate and parallel elastic tabs at its front end. The base of the elastic tabs connects to the end cap, and the head of the elastic tabs has snap-fit ​​teeth corresponding to the snap-fit ​​groove. The snap-fit ​​groove is located on the side of the water inlet valve, and the mounting hole is located through the rear side of the control panel. The snap-fit ​​component passes through the mounting hole and the snap-fit ​​groove and is secured. This installation structure for the washing machine water inlet valve is simple to install and easy to manufacture. By sequentially inserting the snap-fit ​​component into the mounting hole and the snap-fit ​​groove and securing them together, the washing machine water inlet valve and control panel are assembled. The operation is simple and labor-saving, with good assembly coordination and stability, and high assembly efficiency. However, when repairing or replacing the inlet valve, the inlet valve is not easy to disassemble and may require forceful disassembly, which can easily damage the installation structure and reduce the efficiency of repair and replacement. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an installation structure for a water inlet valve of a household appliance.

[0004] The technical solution adopted by this utility model to solve its technical problem is a water inlet valve installation structure for household appliances, including a water inlet valve body. T-shaped inserts are provided in the snap-fit ​​grooves on both sides of the water inlet valve body. Each insert is fitted with a sleeve. Each sleeve is provided with two sliding grooves. Each sliding groove is provided with a locking block. Multiple locking slots that fit the ends of the locking blocks are provided on both sides of the two inserts. A pull rod is fixed to the side wall of each locking block. A spring is fitted on each pull rod. Through holes that fit the pull rods are provided on both sides of the two sleeves.

[0005] By adopting the above technical solution, after the water inlet connector of the water inlet valve body passes through the through hole on the washing machine, the ends of the two plug rods are placed in the snap-fit ​​grooves on both sides of the water inlet valve body and pass through the mounting holes on the washing machine. Then, the pull rod is pulled to put the two clips on the two plug rods and squeeze the two plug rods. After the two plug rods and the two clips are tightly against the washing machine, the pull rod is released, and the spring pushes the locking block to reset. The end of the locking block is inserted into the locking groove on the plug rod, which can prevent the plug rod from sliding and facilitate the installation of the water inlet valve body. The water inlet pipe is threaded to the water inlet valve body and the water inlet pipe is tightened to keep the water inlet valve body in a stable state. When disassembling, simply pull the pull rod to remove the clips from the plug rods, and pull out the two plug rods to remove the water inlet valve body for repair or replacement.

[0006] Specifically, rubber pads are fixed to the side walls of both insertion rods and both ferrules.

[0007] By adopting the above technical solution, after the ferrule is installed on the plug rod, the rubber pad is in close contact with the washing machine, which improves the stability of the plug rod and the water inlet valve body.

[0008] Specifically, both of the aforementioned inserts and sleeves have multiple anti-slip protrusions integrally formed.

[0009] By adopting the above technical solution, the anti-slip protrusions facilitate gripping the insertion rod and the ferrule.

[0010] Specifically, each of the pull rods has a pull block fixed to the end away from the locking block.

[0011] By adopting the above technical solution, the design of the pull block facilitates the pulling of the lever.

[0012] Specifically, each of the two sleeves has two positioning blocks integrally formed inside, and each of the two insert rods has two guide grooves that are adapted to the positioning blocks.

[0013] By adopting the above technical solution, the positioning block and guide groove can prevent the sleeve from rotating on the insertion rod, which would prevent the card block from being smoothly inserted into the slot on the insertion rod.

[0014] The beneficial effects of this utility model are:

[0015] (1) The water inlet valve installation structure of the household appliance described in this utility model involves passing the water inlet connector of the water inlet valve body through the through hole on the washing machine, placing the ends of the two plug rods on the snap-fit ​​grooves on both sides of the water inlet valve body and passing them through the mounting holes on the washing machine, then pulling the pull rod to put the two clips on the two plug rods and squeeze the two plug rods. After the two plug rods and the two clips are tightly against the washing machine, the pull rod is released, and the spring pushes the locking block to reset. The end of the locking block is inserted into the locking groove on the plug rod, which can prevent the plug rod from sliding and coming out of the mounting hole, thus facilitating the installation of the water inlet valve body. The water inlet pipe is threaded to the water inlet valve body and the water inlet pipe is tightened to keep the water inlet valve body in a stable state. When disassembling, simply pull the pull rod to remove the clips from the plug rods, and pull out the two plug rods to remove the water inlet valve body for repair or replacement.

[0016] (2) The water inlet valve installation structure of the household appliance described in this utility model has a rubber pad that is in close contact with the washing machine after the ferrule is installed on the plug rod, which improves the stability of the plug rod and the water inlet valve body. The positioning block and guide groove can prevent the ferrule from rotating on the plug rod, which would prevent the ferrule from being inserted into the slot on the plug rod smoothly.
