A high-impact resistant washing machine lid

Abstract

This utility model discloses a highly impact-resistant washing machine lid, which is installed together with the washing machine frame. It includes an upper lid with mounting grooves at both opposite ends of its back side. A support platform is formed around the back of the upper lid, and a wooden buffer layer is adhered to the back of the upper lid. A support frame is fixed to the back of the upper lid, and the wooden buffer layer is located in the middle of the upper lid and the support frame. A buffer gap is provided between the support frame and the wooden buffer layer. In this utility model, the wooden buffer layer is made of hardwood. The dense surface of the hardwood reflects some sound waves, reducing noise propagation. Simultaneously, the internal fiber structure of the hardwood absorbs low-frequency vibration energy, reducing resonance. The buffer gap cuts off the rigid vibration transmission path between the support frame and the wooden buffer layer, reducing the transmission of washing machine vibration to the wooden buffer layer, thereby reducing vibration noise.

Description

Technical fields:

[0001] This utility model relates to a washing machine cover with high impact resistance, which belongs to the field of washing machine structure technology. Background technology:

[0002] As an essential home appliance in modern households, the structural design of washing machines directly impacts the user experience. Small drum washing machines, due to their compact size, moderate capacity, and energy and water efficiency, are widely used in small apartments, dormitories, and other similar settings. The washing machine lid, as a crucial component of the machine, not only encloses the washing space but also needs sufficient structural strength to withstand the impacts and loads of daily use. Because of their compact size and diverse installation environments (such as narrow balconies and bathrooms), small drum washing machines are more susceptible to external impacts.

[0003] Currently, most small drum washing machine lids on the market are made of ordinary ABS or PP plastic injection molding, which has problems such as large material deformation and insufficient toughness in terms of impact resistance. Some manufacturers are currently trying to improve the strength of the lid by increasing the wall thickness or using metal reinforcements. However, increasing the wall thickness will lead to increased weight and cost, and using metal reinforcements can only increase local strength and is prone to corrosion and increases manufacturing costs.

[0004] Therefore, it is indeed necessary to improve existing technologies to address their shortcomings. Utility model content:

[0005] This invention provides a washing machine lid with high impact resistance to solve the problems existing in the prior art. Through comprehensive improvements in material combination, structural reinforcement and buffer design, the impact resistance of the lid is significantly improved under the premise of low cost.

[0006] The technical solution adopted by this utility model is as follows: a washing machine cover with high impact resistance, which is installed together with the washing machine frame, including an upper cover, with mounting grooves formed at the two opposite ends of the back of the upper cover, a support platform formed around the back of the upper cover, a wooden buffer layer glued to the back of the upper cover, an upper cover support frame fixed to the back of the upper cover, the wooden buffer layer being located in the middle of the upper cover and the upper cover support frame, and a buffer gap being provided between the upper cover support frame and the wooden buffer layer.

[0007] Furthermore, the front of the top cover is smooth and glossy, while the back is provided with anti-slip texture.

[0008] Furthermore, the upper cover plate is integrally injection molded from plastic.

[0009] Furthermore, the rear end of the upper cover plate is provided with a threaded hole, and a screw is installed in the threaded hole to fix the upper cover plate to the rear cover plate of the washing machine.

[0010] Furthermore, the wooden buffer layer is a rectangular hardwood board with a thickness of 5mm.

[0011] Furthermore, the upper cover plate support frame is a bent sheet metal part.

[0012] Furthermore, the buffer gap is an air layer of 0.8 to 1.5 mm.

[0013] This utility model has the following beneficial effects:

[0014] (1) Enhanced impact resistance: The wooden buffer layer and the top cover form a hardness gradient transition. The impact energy is absorbed in stages through the elastic deformation of the wooden buffer layer. At the same time, the top cover support frame transmits the vertical impact on the top cover and the wooden buffer layer to the surrounding area of ​​the top cover and the whole frame of the washing machine, which greatly improves the impact resistance and deformation resistance of the top cover.

[0015] (2) Good structural integrity and sealing performance: The top cover is made of one-piece injection molding, which eliminates the weakness of the joints in the traditional splicing structure, makes the stress distribution uniform, and improves the overall bending strength; the molding surface of the top cover is continuous and uninterrupted, which effectively prevents liquid from seeping into the internal structure along the joints.

[0016] (3) Enhanced noise reduction effect: The wooden buffer layer can effectively block the noise generated by washing and spin-drying inside the drum washing machine. At the same time, the wooden buffer layer and the upper cover support frame have a buffer gap, cutting off the rigid connection between the two, which can reduce the transmission of mechanical vibration to the wooden buffer layer, thereby reducing the vibration of the upper cover.

[0017] (4) Good appearance: The wooden buffer layer is glued to the back of the top cover, which enhances the structure while ensuring the appearance. Attached image description:

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] This utility model relates to a highly impact-resistant washing machine cover, which is installed together with the washing machine frame 6. It includes an upper cover 1, which is integrally injection molded from plastic. The front of the upper cover 1 is smooth and glossy, while the back has anti-slip textures, and mounting grooves 8 are formed at the two opposite ends of the back. Support platforms 4 are formed around the back of the upper cover 1, which contact the washing machine frame 6 to increase the stress area and improve the overall aesthetics. The rear end of the upper cover 1 has a threaded hole (not shown), through which screws are inserted to fix the upper cover 1 to the washing machine rear cover (not shown).

[0025] A wooden cushioning layer 2, 5mm thick rectangular solid wood board, is glued to the back of the top cover 1 using adhesive. This solid wood board has a high modulus of elasticity, providing better rigid support for the top cover 1 and effectively transmitting and dispersing impacts. When the top cover 1 is subjected to localized impacts (such as falling heavy objects or hammer blows), the solid wood board can distribute the localized impact force over a larger area, thereby reducing the peak stress of the top cover 1 and preventing deformation or breakage. Simultaneously, the dense surface of the solid wood board reflects some sound waves, reducing noise propagation. Furthermore, the internal fiber structure of the solid wood board absorbs low-frequency vibration energy, reducing resonance. Its sound insulation effect is greater than that of a single-layer plastic board, effectively reducing noise transmitted from inside the washing machine.

[0026] The back of the top cover plate 1 is bolted to a top cover plate support frame 3, and a wooden buffer layer 2 is located between the top cover plate 1 and the top cover plate support frame 3. The top cover plate support frame 3 is a bent sheet metal part, and a buffer gap 5 is provided between the top cover plate support frame 3 and the wooden buffer layer 2, which can further improve the structure's impact resistance, vibration reduction and noise reduction capabilities, and mechanical stability. The buffer gap 5 is an air layer of 0.8 to 1.5 mm. When the top cover plate 1 is impacted, the top cover plate 1 first undergoes elastic deformation. The buffer gap provides additional deformation space, prolonging the impact time and thus reducing the instantaneous impact force. At the same time, the buffer gap cuts off the rigid vibration transmission path between the top cover plate support frame 3 and the hardwood board, reducing the transmission of washing machine vibration to the hardwood board. When the top cover plate 1 is subjected to excessive impact, the top cover plate 1 deforms downward, causing the hardwood board to move downward, so that the top cover plate support frame 3 contacts the hardwood board to form a force transmission surface, converting the vertical load on the hardwood board into a horizontal component force and transmitting it to the edge of the top cover plate and the washing machine frame.

[0027] In daily use, most of the weight of items piled on the top cover 1 is transferred to the washing machine frame 6 through the support platform 4 in the top cover 1, thus transferring the force to the ground. When a heavy object falls from a height and hits the top cover 1, the wooden buffer layer 2 connected to the top cover 1 disperses the local impact force over a larger area, thereby reducing the peak stress of the top cover 1 and preventing deformation or breakage. When the impact force is too large, the top cover 1 undergoes elastic deformation, and the buffer gap 5 provides additional deformation space, prolonging the impact time and reducing the instantaneous impact force. At the same time, it moves the wooden buffer layer 2 downward, causing the top cover support frame 6 to contact the wooden buffer layer 2 to form a force transmission surface, converting the vertical load on the wooden board into a horizontal component force and transferring it to the edge of the top cover 1 and the washing machine frame 6.

[0028] When the washing machine is operating, especially during the spin-drying process, its internal mechanisms generate noise. The wooden buffer layer 2 is made of hardwood. The dense surface of hardwood can reflect some sound waves, reducing the outward transmission of noise. At the same time, the internal fiber structure of the hardwood can absorb low-frequency vibration energy, reducing resonance. The buffer gap 5 cuts off the rigid vibration transmission path between the upper cover support frame 3 and the wooden buffer layer 2, reducing the transmission of washing machine vibration to the wooden buffer layer, thereby reducing vibration noise.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
