Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and more specifically, to a mini washing machine. Background Technology

[0002] In the current field of home appliance technology, mini washing machines, as a convenient and efficient washing device, are widely welcomed by consumers due to their compact size and flexible usage scenarios. Mini washing machines typically have a sealing structure between the outer drum and the lid, called a door seal or sealing ring. Its main function is to seal the outer drum and lid, preventing wash water from leaking out of the outer drum during washing, spin-drying, or drying.

[0003] Traditional sealing ring designs are relatively simple, typically acting only as a barrier, snapped between the outer drum edge and the cover plate to form a single sealing surface. While this design does prevent liquid leakage to some extent, its sealing effect is not ideal. For example, patent CN215051415U discloses a door sealing structure for a mini drum washing machine, which still suffers from the aforementioned shortcomings. Due to limitations in sealing ring materials, structural design, and installation methods, a single sealing surface often cannot withstand the strong water pressure generated during washing and spin-drying, as well as the impact of high-temperature steam during drying. This causes wash water to easily seep out from the tiny gaps between the sealing ring and the drum or cover plate, affecting not only the washing machine's cleaning performance and energy efficiency but also potentially damaging its electronic components.

[0004] Furthermore, during the drying process, if the sealing ring is not airtight, high-temperature steam may escape from the gaps, reducing drying efficiency and posing a safety hazard. Therefore, the existing sealing ring design for mini washing machines has significant shortcomings in terms of sealing performance and safety, necessitating a more reliable and efficient sealing solution to improve the overall performance and user experience of the washing machine. Utility Model Content

[0005] In view of this, the present invention aims to propose a mini washing machine to solve the problem that the sealing structure of the outer drum cover of the existing mini washing machine is not tight, and water and air are easily leaked at the sealing structure when the mini washing machine is running, which poses a safety hazard.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A mini washing machine includes an outer drum with a top cover. The top cover has an opening for loading and unloading clothes. A cover plate is provided at the opening, which can be opened and closed relative to the top cover to seal the opening. A sealing structure is provided at the opening, including a Y-shaped sealing ring, which can form a double seal between the cover plate and the top cover.

[0008] The mini washing machine described in this application can form a double sealing structure between the cover plate and the top cover by setting a Y-shaped sealing ring at the opening, which significantly improves the sealing effect. During the operation of the mini washing machine, it can effectively prevent washing water and high-temperature steam from leaking out from the sealing structure, which improves both safety and drying effect.

[0009] Furthermore, the Y-shaped sealing ring includes a sealing edge, a connecting edge, and a fixing edge connected together from top to bottom. The sealing edge includes a first flange and a second flange. The lower end of the first flange is connected to the lower end of the second flange. The first flange is inclined away from the opening, and the second flange is inclined towards the opening. The fixing edge cooperates with the top cover to fix the Y-shaped sealing ring and the top cover together. The first flange can form a primary seal between the cover plate and the top cover, and the second flange can form a secondary seal between the cover plate and the top cover.

[0010] The first and second flanges of the Y-shaped sealing ring are inclined in opposite directions, which facilitates the formation of a double seal between the cover plate and the top cover. This effectively prevents washing water and steam from seeping out from the gaps in the sealing structure, improves the sealing performance of the washing machine, and enables the washing machine to withstand the strong water pressure during washing and spin-drying as well as the impact of high-temperature steam during drying.

[0011] Furthermore, the sealing structure includes a clamp plate, which cooperates with the top cover to fix the Y-shaped sealing ring.

[0012] This design facilitates the installation and removal of the Y-shaped seal ring, while also improving the connection strength between the Y-shaped seal ring and the top cover.

[0013] Furthermore, the lower end of the top cover is provided with a first folded edge, the first folded edge is provided around the opening, and the lower end of the first folded edge is provided with a second folded edge, the second folded edge being located on the side of the first folded edge closer to the opening;

[0014] The clamping plate includes a flat plate, one end of which is provided with a first vertical plate and the other end of which is provided with a second vertical plate. The first vertical plate and the second vertical plate are located at the upper end of the flat plate. The first folded edge and the second folded edge are located between the first vertical plate and the second vertical plate, and the upper end face of the second folded edge and the upper end face of the second vertical plate are located in the same plane.

[0015] The first folded edge has a first protrusion on its side wall, which is located away from the opening. The first vertical plate has a first clearance hole. The first protrusion and the first clearance hole cooperate to fix the top cover and the clamping plate. The second folded edge cooperates with the flat plate to reinforce and fix the fixed edge.

[0016] This design facilitates the assembly of the clamping plate and the top cover. At the same time, the cooperation between the second folded edge and the flat plate makes it easy to reinforce and fix the fixed edge, which can improve assembly efficiency and the firmness of the Y-shaped sealing ring.

[0017] Furthermore, a second protrusion is provided at the lower end of the second folded edge, a second clearance hole is provided on the fixed edge, and a third clearance hole is provided on the flat plate. The second protrusion passes through the second clearance hole and the third clearance hole from top to bottom in sequence, and is used for connection and fixation between the top cover, the Y-shaped sealing ring and the clamping plate.

[0018] This design simplifies the installation process between the top cover, the Y-shaped sealing ring, and the clamping plate, improving installation efficiency and the strength of the connection between the top cover and the sealing structure.

[0019] Furthermore, a third flange is provided at the lower end of the connection point between the first flange and the second flange. The third flange is located on the side near the opening. The upper end of the connecting edge is connected to the end of the third flange away from the opening. The lower end of the third flange abuts against the upper end of the second vertical plate to provide support for the sealing edge.

[0020] This design provides additional support to the Y-shaped sealing ring, making it more able to withstand the strong water pressure during washing and dehydration, as well as the impact of high-temperature steam during drying, thus enhancing the sealing effect of the first and second flanges.

[0021] Furthermore, the angle α between the first flange and the second flange is 75°≤α≤120°.

[0022] This design allows the first and second flanges to be stressed more evenly, avoiding seal failure or damage caused by uneven stress. At the same time, this design allows the Y-shaped sealing ring to better adapt to the space between the cover plate and the top cover, ensuring that the sealing edge can fit tightly between the two and enhance the sealing effect.

[0023] Furthermore, the cover plate is provided with a pin, the top cover is provided with a mounting groove, the side wall of the mounting groove is provided with an insertion hole, and the pin is rotatably connected to the insertion hole, so that the cover plate can be opened and closed relative to the top cover.

[0024] This design allows the lid to be easily opened and closed on the top cover, making it convenient for users to put in and take out clothes. This not only improves the ease of use but also ensures the stability of the lid during the operation of the washing machine.

[0025] Furthermore, the cover plate is provided with a locking structure, which includes a lock head and an unlock button. The lock head is located at the front end of the cover plate, and the unlock button is located at the upper end of the cover plate. The lock head and the unlock button are connected and fixed together. The lower end of the top cover is provided with a first folded edge, which surrounds the opening and has a slot. The slot engages with the lock head. By pushing the unlock button, the lock head can be moved in the back-and-forth direction for locking or unlocking the top cover and the cover plate.

[0026] This design makes it easy for users to open or close the cover, and improves the seal between the cover and the top cover.

[0027] Furthermore, the upper end of the cover plate is provided with a latching groove, which is located behind the unlocking button and is used to open or close the cover plate.

[0028] This design allows users to easily open or close the cover by applying force with their fingers or hands, improving ease of use.

[0029] Compared with the prior art, the mini washing machine of this utility model has the following advantages:

[0030] 1) By setting a Y-shaped sealing ring at the opening, a double sealing structure can be formed between the cover and the top cover, which significantly improves the sealing effect. During the operation of the mini washing machine, it can effectively prevent washing water and high-temperature steam from leaking out from the sealing structure, which improves both safety and drying effect.

[0031] 2) The first and second flanges of the Y-shaped sealing ring are inclined in opposite directions, which facilitates the formation of a double seal between the cover plate and the top cover, effectively preventing washing water and steam from seeping out from the gaps in the sealing structure, improving the sealing performance of the washing machine, and enabling the washing machine to adapt to the strong water pressure during washing and spin-drying as well as the impact of high-temperature steam during drying.

[0049] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0050] Example 1

[0051] like Figure 1-15 As shown, a mini washing machine includes an outer drum 100, a top cover 1, an opening 10 for loading and unloading clothes, a cover plate 200 for opening and closing relative to the top cover 1 to seal the opening 10, and a sealing structure including a Y-shaped sealing ring 2 for forming a double seal between the cover plate 200 and the top cover 1.

[0052] The mini washing machine described in this application, by setting a Y-shaped sealing ring 2 at the opening 10, can form a double sealing structure between the cover 200 and the top cover 1 when the cover 200 is closed. Compared with the traditional single sealing surface, the sealing effect is significantly improved. During the operation of the mini washing machine, it can effectively prevent washing water and high-temperature steam from leaking out from the sealing structure, which improves both safety and drying effect.

[0053] As a preferred example of this application, the Y-shaped sealing ring 2 includes a sealing edge 21, a connecting edge 22, and a fixing edge 23 connected together from top to bottom. The sealing edge 21 includes a first flange 211 and a second flange 212. The lower end of the first flange 211 is connected to the lower end of the second flange 212. The first flange 211 is inclined away from the opening 10, and the second flange 212 is inclined towards the opening 10. The fixing edge 23 cooperates with the top cover 1 to fix the Y-shaped sealing ring 2 and the top cover 1 together. The first flange 211 can form a primary seal between the cover plate 200 and the top cover 1, and the second flange 212 can form a secondary seal between the cover plate 200 and the top cover 1.

[0054] Specifically, the first flange 211 and the second flange 212 of the Y-shaped sealing ring 2 are inclined in opposite directions, which facilitates the formation of a double seal between the cover plate 200 and the top cover 1.

[0059] The first folded edge 11 has a first protrusion 111 on its side wall. The first protrusion 111 is located on the side away from the opening 10. The first vertical plate 31 has a first clearance hole 311. The first protrusion 111 and the first clearance hole 311 cooperate to fix the top cover 1 and the clamping plate 3. The second folded edge 12 cooperates with the flat plate 30 to reinforce and fix the fixed edge 23.

[0060] Specifically, the first folded edge 11 and the first vertical plate 31 are connected by the first protrusion 111 and the first clearance hole 311, which facilitates the assembly between the clamping plate 3 and the top cover 1. At the same time, the second folded edge 12 and the flat plate 30 are used to facilitate the reinforcement and fixation of the fixed edge 23, which can improve the assembly efficiency and the firmness of the Y-shaped sealing ring 2.

[0061] As a preferred example of this application, the lower end of the second folded edge 12 is provided with a second protrusion 121, the fixed edge 23 is provided with a second clearance hole 232, and the flat plate 30 is provided with a third clearance hole 303.

[0062] Specifically, this design simplifies the installation steps between the top cover 1, the Y-shaped sealing ring 2, and the clamping plate 3, improving installation efficiency and the firmness of the connection between the top cover 1 and the sealing structure.

[0063] As a preferred example of this application, a third flange 213 is provided at the lower end of the connection point between the first flange 211 and the second flange 212. The third flange 213 is located on the side close to the opening 10. The upper end of the connecting edge 22 is connected to the end of the third flange 213 away from the opening 10. The lower end of the third flange 213 abuts against the upper end of the second vertical plate 32 to provide support for the sealing edge 21.

[0064] Specifically, the lower end of the third flange 213 abuts against the upper end of the second vertical plate 32, providing additional support for the Y-shaped sealing ring 2, making it more able to withstand the strong water pressure during washing and dehydration and the impact of high-temperature steam during drying, thus enhancing the sealing effect of the first flange 211 and the second flange 212.

[0065] As a preferred example of this application, the angle α between the first flange 211 and the second flange 212 is 75°≤α≤120°.

[0066] Specifically, this design allows the first flange 211 and the second flange 212 to be subjected to force more evenly, avoiding sealing failure or damage due to uneven force. At the same time, this design allows the Y-shaped sealing ring 2 to better adapt to the space between the cover plate 200 and the top cover 1, ensuring that the sealing edge 21 can fit tightly between the two, enhancing the sealing effect. On the other hand, the appropriate angle α can also ensure that the Y-shaped sealing ring 2 is not easily deformed or damaged during installation and use, thereby extending its service life.
