Description

Technical Field

[0001] This utility model relates to the field of washing machines, specifically a liquid level detection wiring harness for washing machines. Background Technology

[0002] The liquid level detection harness for washing machines is a crucial component. It detects the water level inside the washing machine, ensuring it operates at the set water level. This harness typically consists of several parts, including wires, plugs, terminals, and sensors. The wires transmit signals, the plugs and terminals provide connection and fixation, and the sensor is the key component for detecting the water level. Traditional washing machine liquid level detection harnesses have certain shortcomings in sealing. For example, the connection between the power plug and the power receiver is often not tight enough, making it prone to loosening during washing due to vibration or water flow, leading to water seepage, short circuits, or damage. Therefore, we have proposed a new liquid level detection harness for washing machines. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a liquid level detection wiring harness for washing machines, which solves the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a liquid level detection wiring harness for a washing machine, comprising a wiring harness and a power receiving end, wherein a sensor is fixedly connected to one end of the wiring harness, a power cover is fixedly connected to the other end of the wiring harness, a sealing sleeve is fixedly connected to one side of the power receiving end, a power plug is fixedly connected to the side of the power cover near the power receiving end, and two sets of plugs are fixedly connected to one side of the power plug, further comprising:

[0005] A sealing connector assembly is provided on the power cover and the power receiver to seal the power plug to the power receiver and prevent water from entering.

[0006] Preferably, the sealing plug assembly includes a sealing rubber ring, a fixing rod, and a plug hole. A sealing rubber ring is fixedly provided on one side of the power cover corresponding to the outer wall of the power plug. A horizontal fixing rod is fixedly connected above the sealing rubber ring on one side of the power cover. A plug hole extending from the top to the bottom is provided on the fixing rod near its end.

[0007] Preferably, the sealing plug assembly further includes a mounting bracket, a plug, a limiting cap, and a return spring. The top of the sealing sleeve is fixedly provided with the mounting bracket, and the top of the mounting bracket is slidably mounted with a plug extending into the mounting bracket. The outer wall of the plug is fitted with a return spring corresponding to the inner wall of the mounting bracket, and the outer wall of the plug is fitted between the limiting cap and the top inner wall of the mounting bracket.

[0008] Preferably, the bottom of the insert and the end of the fixed insert are both beveled, and the insert slides into the insertion hole.

[0009] Preferably, one side of the sealing sleeve has an opening that matches the sealing rubber ring.

[0010] Preferably, the sealing rubber ring is circular, and the power cover is slidably inserted into the ring opening through the sealing rubber ring.

[0011] Compared with the prior art, this utility model provides a liquid level detection wiring harness for washing machines, which has the following beneficial effects:

[0012] 1. The washing machine uses a liquid level detection wiring harness. Through the sealed plug assembly, the connection between the power plug and the power receiver is made tighter. The sealing rubber ring ensures that the power cover fits tightly inside the ring of the sealing sleeve when it is pushed into the power receiver, effectively preventing water from seeping in from the connection gap, thereby avoiding the risk of short circuit or damage.

[0013] 2. The washing machine uses a liquid level detection harness with a beveled design between the fixing rod and the drum. This design allows the fixing rod to lift the drum upwards during sliding, while the compression force of the return spring pushes the drum downwards through the limit cover. This ensures that the power plug is firmly fixed inside the power receiver, maintaining connection stability even when subjected to vibration or water flow during the washing process.

[0014] 3. The liquid level detection wiring harness used in this washing machine effectively prevents moisture from corroding and damaging the circuit by enhancing its sealing and stability, thereby extending the service life of the washing machine's liquid level detection wiring harness. At the same time, the tight connection between the components also reduces the risk of damage caused by friction and wear. Attached Figure Description

[0027] The sealing rubber ring 8 is circular, and the power cover 3 is slidably inserted into the ring opening 11 through the sealing rubber ring 8.

[0028] Structural Description: Wiring Harness 1: As the core component of the washing machine's liquid level detection system, it is responsible for transmitting signals from the sensor to the washing machine control unit. Wiring Harness 1 contains multiple wires to ensure stable signal transmission;

[0029] Sensor 2: Fixed to one end of wiring harness 1, used to accurately detect the water level inside the washing machine. Sensor 2 can convert changes in water level into electrical signals, which are then transmitted by wiring harness 1.

[0030] Power cover 3: Fixed to the other end of wire harness 1, with a fixed structure designed with a sealed plug-in assembly. During the pushing process, the power cover 3 achieves a tight connection with the power receiving end through components such as the sealing rubber ring 8 and the fixing plug 9.

[0031] Power receiver 4: As part of the main body of the washing machine, it is used to receive the power plug 6 from the power cover 3. The power receiver 4 is provided with a ring opening 11 that is adapted to the sealing rubber ring 8, and a mounting bracket 12 for installing the sealing plug assembly, etc.

[0032] Sealing sleeve 5: It is fixed to one side of the power receiving end 4, providing space for the power plug 6 to be inserted, and enhancing the sealing effect through its inner wall's tight contact with the sealing rubber ring 8;

[0033] Power plug 6: It is fixed to the side of the power cover 3 near the power receiver 4 and is used to connect to the power receiver 4 to achieve electrical connection.

[0034] Plug 7: As part of or an additional structure closely connected to the power plug 6, the metal plug 7 is made of high-quality metal material, providing excellent electrical connection performance and corrosion resistance;

[0035] Sealing rubber ring 8: Fixed to one side of the power cover 3, corresponding to the outer wall of the power plug 6. When the power cover 3 is pushed into the power receiving end 4, the sealing rubber ring 8 can fit tightly inside the ring opening 11, effectively preventing moisture from seeping in;

[0036] Fixed insertion rod 9: Fixed to one side of the power cover 3, above the sealing rubber ring 8. The fixed insertion rod 9 is provided with an insertion hole 10 for plugging into the insertion tube 13, thereby fixing the relative position of the power cover 3 and the power receiving end 4;

[0037] Insertion hole 10: Located at the end of the fixed insertion rod 9, it is used to receive the insertion of the insertion tube 13, achieving a tight connection between the two. The design of the insertion hole 10 incorporates a beveled cut to gradually conform to the beveled cut of the insertion tube 13;

[0038] Ring 11: Opened on one side of the sealing sleeve 5, adapted to the sealing rubber ring 8, used to receive the insertion of the power cover 3 and provide a sealing contact surface;

[0039] Mounting bracket 12: Fixed to the top of the power receiver 4, used to mount components such as the insert 13, the limiting cover 14, and the return spring 15. The design of mounting bracket 12 takes into account both smooth sliding and stability;

[0040] Insert 13: Slidably installed inside the mounting bracket 12, corresponding to the insertion hole 10 of the fixing rod 9. The bottom of the insert 13 and the end of the fixing rod 9 are both beveled, which facilitates their gradual contact and insertion during sliding.

[0041] Limiting cover 14: Sleeves onto the outer wall of the insert 13, corresponding to the top inner wall of the mounting bracket 12. During the upward sliding of the insert 13, the limiting cover 14 compresses the return spring 15, causing it to deform and shorten.

[0042] Return spring 15: Sleeves on the outer wall of the insert 13, corresponding to the top inner wall of the limiting cover 14 and the mounting bracket 12. When the insert 13 slides to directly below the insertion hole 10, the return spring 15 pushes the insert 13 downward through the squeezing force of the limiting cover 14, achieving a tight connection with the insertion hole 10.

[0043] Working principle: In use, first push the power cover 3 into the sealing sleeve 5, so that the power plug 6 enters the sealing sleeve 5. During the movement of the power cover 3, the end of the fixing rod 9 gradually contacts the bottom of the plug 13. As the fixing rod 9 gradually slides, the fixing rod 9 slowly fits into the oblique cut of the plug 13 through the oblique cut of the end, so that the fixing rod 9 gradually squeezes the plug 13 to slide upward on the mounting bracket 12. During the upward sliding, the limiting cover 14 squeezes the return spring 15, causing the return spring 15 to deform and shorten. When the plug hole 10 on the fixing rod 9 slides to directly below the plug 13, the squeezing force of the return spring 15 pushes the plug 13 downward through the limiting cover 14, so that the bottom end of the plug 13 is inserted into the plug hole 10, thereby fixing the power cover 3 in the sealing sleeve 5. The sealing rubber ring 8 enters the ring opening 11 on the sealing sleeve 5 through the movement of the power cover 3, increasing the sealing effect and preventing water from entering the sealing sleeve 5.
