Description

Technical Field

[0001] The present application relates to the technical field of washing machines, and particularly relates to a washing machine door body and a washing machine with a sterilization function. Background Art

[0002] To enrich the functions of washing machines, some existing washing machines are integrated with ultraviolet lamps to sterilize clothes. When the washing machine is running, the ultraviolet lamps can project ultraviolet light into the drum. While the drum drives the washing machine to tumble and wash clothes, the input ultraviolet light disinfects and sterilizes the clothes, thereby improving the cleanliness and health of the clothes. For example, Chinese Patent Publication No. CN117702426A discloses a mini washing machine with an ultraviolet disinfection function. Specifically, it provides light-transmitting small holes on the decorative panel of the door body, and installs a sterilization lamp inside the decorative panel. When working, the ultraviolet light emitted by the sterilization lamp passes through the small holes and the door glass and projects into the drum to achieve sterilization. This solution can solve the problem that the traditional sterilization lamp setting structure is not applicable to mini washing machines. However, this solution still has certain defects: only one ultraviolet point light source is set inside the decorative panel, and the point light source can only project into the washing drum through the small holes, resulting in a small illumination area that can be formed inside the washing drum, and thus it is impossible to quickly and comprehensively sterilize the clothes in the drum, suffering from problems such as low sterilization efficiency and incomplete sterilization effect. Summary of the Utility Model

[0003] The purpose of the embodiments of the present utility model is to provide a washing machine door body and a washing machine with a sterilization function, which can solve the above problems existing in the prior art.

The ultraviolet lamp board and the suction cup are arranged on the same side of the support plate, and the suction cup is adsorbed and fixed on the door glass, so that the ultraviolet lamp board can project ultraviolet light outward through the door glass.

[0006] Optionally, the ultraviolet lamp board is an annular lamp board, and the suction cup is located in the central area of the ultraviolet lamp board.

[0007] Optionally, a diffusion cover is further installed on the support plate, and the diffusion cover covers the outside of the ultraviolet lamp board to diffuse the ultraviolet light emitted by the ultraviolet lamp board.

[0008] Optionally, a wire threading pipe is provided on the side of the support plate facing away from the ultraviolet lamp panel. The wire threading pipe extends towards the door body, and the power supply wire of the ultraviolet lamp panel passes through the wire threading pipe.

[0009] Optionally, an air extraction nozzle is provided on the support plate. The air extraction nozzle communicates with the inner cavity of the suction cup. A sealing member is installed on the air extraction nozzle. By sealing the air extraction nozzle with the sealing member, a negative pressure state is maintained inside the suction cup.

[0010] Optionally, the sealing member is a one-way valve that opens unidirectionally in the direction away from the inner cavity of the suction cup, so that the suction cup can exhaust air unidirectionally through the sealing member.

[0011] Optionally, the sealing member is detachably installed on the air extraction nozzle.

[0012] Optionally, the air extraction nozzle has an internal thread, and the sealing member has an external thread. The sealing member is threadedly installed on the air extraction nozzle.

The steel ball is located on the side of the sealing ring facing away from the suction cup. The inner wall of the support cylinder is provided with an inner shoulder. One end of the spring abuts against the inner shoulder, and the other end abuts against the steel ball. The spring force pushes the steel ball to tightly press against the sealing ring to seal the air extraction nozzle.

[0014] On the other hand, a washing machine is provided, including the washing machine door body with a sterilization function described above.

[0015] The beneficial effects of the present application are as follows: The present utility model provides a washing machine door body with a sterilization function and a washing machine. By providing an ultraviolet lamp assembly in the accommodation space of the door body and the door glass, ultraviolet light can be projected into the drum through the door glass during washing for sterilization work. The ultraviolet lamp assembly of this solution specifically includes structures such as a support plate, an ultraviolet lamp panel, and a suction cup. The ultraviolet lamp panel and the suction cup are both installed on the support plate. The suction cup can firmly suck the ultraviolet lamp assembly onto the inner surface of the door glass, so that the ultraviolet lamp panel can project ultraviolet light close to the surface of the door glass. The ultraviolet lamp panel used in this solution is a surface light source structure. Compared with the traditional point light source, its illumination area is wider, and it can achieve global illumination sterilization in the drum, effectively improving the sterilization efficiency and the sterilization effect. Importantly, this solution uses a suction cup structure to fix the ultraviolet lamp assembly, without the need for operations such as drilling holes, grooving, or gluing on the door glass.

[0028] To make the technical problems solved by the present application, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0029] In the description of the present application, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] In the present application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0031] To enrich the usage functions of washing machines, some existing washing machines are integrated with ultraviolet lamps to sterilize clothes. When the washing machine is running, the ultraviolet lamps can project ultraviolet light into the drum. While the drum drives the washing machine to tumble and wash the clothes, the ultraviolet light input disinfects and sterilizes the clothes, thereby improving the cleanliness and health of the clothes. For example, Chinese Patent Publication No. CN117702426A discloses a mini washing machine with an ultraviolet disinfection function. Specifically, it sets light-transmitting small holes on the decorative panel of the door body, and installs a sterilization lamp inside the decorative panel. When working, the ultraviolet light emitted by the sterilization lamp passes through the small holes and the door glass and projects into the drum to achieve sterilization. This solution can solve the problem that the traditional sterilization lamp setting structure is not applicable to mini washing machines. However, this solution still has certain defects: only one ultraviolet point light source is set inside the decorative panel, and the point light source can only project into the washing drum through the small holes, resulting in a small illumination area that can be formed inside the washing drum, and thus it is impossible to quickly sterilize the clothes in the drum comprehensively, having the problems of low sterilization efficiency and incomplete sterilization effect.

[0032] To overcome the above technical problems, referring to Figures 1-9, this embodiment provides a washing machine door body with a sterilization function, including a door main body 1, a door glass 2, and an ultraviolet lamp assembly 3. The door glass 2 is installed inside the door main body 1, and an accommodation space is formed by enclosing between the door glass 2 and the door main body 1. The ultraviolet lamp assembly 3 is arranged in the accommodation space, and it includes a support plate 31, an ultraviolet lamp panel 33, and a suction cup 32. The ultraviolet lamp panel 33 and the suction cup 32 are arranged on the same side of the support plate 31. The suction cup 32 is adsorbed and fixed on the door glass 2, so that the ultraviolet lamp panel 33 can project ultraviolet light outward through the door glass 2.

[0033] Based on the washing machine door body with a sterilization function of this embodiment, by arranging the ultraviolet lamp assembly 3 in the accommodation space of the door main body 1 and the door glass 2, ultraviolet light can be projected into the drum through the door glass 2 for sterilization during washing. The ultraviolet lamp assembly 3 of this solution specifically includes structures such as a support plate 31, an ultraviolet lamp panel 33, and a suction cup 32. The ultraviolet lamp panel 33 and the suction cup 32 are both installed on the support plate 31. The suction cup 32 can firmly suck and tighten the ultraviolet lamp assembly 3 on the inner surface of the door glass 2, so that the ultraviolet lamp panel 33 can project ultraviolet light close to the surface of the door glass 2. The ultraviolet lamp panel 33 used in this solution is a surface light source structure. Compared with the traditional point light source, its illumination area is wider, and it can realize global illumination sterilization in the drum, effectively improving the sterilization efficiency and the sterilization effect. Importantly, this solution uses the suction cup 32 structure to fix the ultraviolet lamp assembly 3, without performing operations such as drilling, grooving, or gluing on the door glass 2. It is not only convenient for repeated disassembly and assembly of the ultraviolet lamp assembly 3, but also does not need to modify the structure of the existing door glass 2 of the washing machine, and can be directly applied to the existing washing machine, having the advantages of low modification cost and low modification difficulty for the existing washing machine.

[0034] In one embodiment, referring to Figure 5 , the ultraviolet lamp panel 33 is an annular lamp panel, and the suction cup 32 is located in the central area of the ultraviolet lamp panel 33.

[0035] The design of the annular lamp panel can ensure a more uniform light distribution of the ultraviolet light in the drum. Since the ultraviolet lamp panel 33 is annular, the light emitted by it can cover a wider area in the drum, reducing the light dead angle, thereby improving the comprehensiveness and efficiency of sterilization. Placing the suction cup 32 in the central area of the ultraviolet lamp panel 33 makes use of the non-light-emitting area in the center of the ultraviolet lamp panel 33 and makes the structure of the entire ultraviolet lamp assembly 3 more compact. This design helps to save space and makes the layout inside the washing machine door body more reasonable. At the same time, the suction cup 32 is located in the center of the ultraviolet lamp panel 33, which can provide a more stable supporting force to ensure that the ultraviolet lamp assembly 3 will not shift or fall off due to vibration during the operation of the washing machine.

[0036] In one embodiment, a diffuser cover 34 is further installed on the support plate 31. The diffuser cover 34 covers the outside of the ultraviolet lamp panel 33, and the ultraviolet light emitted by the ultraviolet lamp panel 33 is diffused through the diffuser cover 34.

[0037] The diffuser cover 34 effectively diffuses the ultraviolet light emitted by the ultraviolet lamp panel 33, enabling the light to be projected more evenly into all corners of the laundry drum. The use of the diffuser cover 34 not only enhances the coverage range of the ultraviolet light but also reduces the problems of local over-intensity or under-intensity that may be caused by direct light irradiation, thereby further improving the sterilization effect and light uniformity. In addition, the diffuser cover 34 may also play a role in protecting the ultraviolet lamp panel 33, preventing it from being directly damaged by the external environment and extending the service life of the ultraviolet lamp assembly 3.

[0038] In one embodiment, referring to Figure 4 , a wire passing tube 311 is provided on the side of the support plate 31 facing away from the ultraviolet lamp panel 33. The wire passing tube 311 extends in the direction of the door body 1, and the power supply wire of the ultraviolet lamp panel 33 passes through the wire passing tube 311.

[0039] By passing the power supply wire through the wire passing tube 311, not only is the interior of the washing machine door body kept clean and orderly, but also problems such as entanglement and wear of the power supply wire during the operation of the washing machine are avoided, improving the safety and reliability of the product.

[0040] In one embodiment, referring to Figure 4 , an air extraction nozzle 312 is provided on the support plate 31. The air extraction nozzle 312 communicates with the inner cavity of the suction cup 32; a blocking member 35 is installed on the air extraction nozzle 312, and the air extraction nozzle 312 is blocked by the blocking member 35 to keep the inside of the suction cup 32 in a negative pressure state.

[0041] To maintain the stable adsorption between the suction cup 32 and the door glass 2, an air extraction nozzle 312 is specifically provided on the support plate 31 of this embodiment. The air extraction nozzle 312 directly communicates with the inner cavity of the suction cup 32, allowing the internal air of the suction cup 32 to be extracted by an external air extraction device. During installation, after the suction cup 32 is attached to the door glass 2, the air inside the suction cup 32 is extracted through the air extraction nozzle 312 to keep the inside of the suction cup 32 in a negative pressure state. To maintain this negative pressure state, a blocking member 35 is also installed on the air extraction nozzle 312. Once the air extraction is completed, the air extraction nozzle 312 can be sealed by the blocking member 35 to ensure that the suction cup 32 can be stably adsorbed on the door glass 2 for a long time. This design not only improves the installation stability of the ultraviolet lamp assembly 3 but also simplifies the installation and maintenance process, making it more convenient for users or maintenance personnel to operate.

[0042] In one embodiment, referring to Figures 7-9, the plugging member 35 is a one-way valve, which is opened unidirectionally in the direction away from the inner cavity of the suction cup 32, so that the suction cup 32 can exhaust air unidirectionally through the plugging member 35.

[0043] The opening direction of the one-way valve is away from the inner cavity of the suction cup 32, that is, it allows gas to be discharged unidirectionally from the inside of the suction cup 32 to the outside, allowing external equipment to easily extract the air inside the suction cup 32. After the air extraction is completed, the one-way valve automatically closes to avoid pressure relief, ensuring that the suction cup 32 can be firmly adsorbed on the door glass 2. This design improves the ease of installation of the ultraviolet lamp assembly 3 and also ensures its stability and reliability during use.

[0044] In one embodiment, the plugging member 35 is detachably installed on the air extraction nozzle 312.

[0045] The plugging member 35 is designed to be detachably installed on the air extraction nozzle 312. This design provides great convenience to users. Especially when it is necessary to disassemble the ultraviolet lamp assembly 3 for maintenance or replacement, users only need to simply remove the plugging member 35, and external air can easily enter the suction cup 32, breaking the negative pressure state and separating the suction cup 32 from the door glass 2. This not only simplifies the disassembly process but also avoids the risk of damage to the washing machine door body or the ultraviolet lamp assembly 3 due to improper disassembly.

[0046] In one embodiment, the air extraction nozzle 312 is provided with internal threads, the plugging member 35 is provided with external threads, and the plugging member 35 is threadedly installed on the air extraction nozzle 312.

[0047] The threaded connection not only enables the plugging member 35 to be tightly installed on the air extraction nozzle 312 to prevent air leakage but also has the advantage of facilitating users' disassembly and installation operations.

[0048] In one embodiment, referring to Figures 8-9 , the plugging member 35 includes a sealing ring 354, a steel ball 353, a spring 352 and a support cylinder 351. The sealing ring 354 is fixed inside the air extraction nozzle 312. The steel ball 353 is located on the side of the sealing ring 354 away from the suction cup 32. The inner wall of the support cylinder 351 is provided with an inner shoulder 3511. One end of the spring 352 abuts against the inner shoulder 3511, and the other end abuts against the steel ball 353. The spring 352 elastically pushes the steel ball 353 to tightly press against the sealing ring 354 to block the air extraction nozzle 312.

[0049] The plugging member 35 includes a sealing ring 354, a steel ball 353, a spring 352, a support tube 351 and other parts, which work together to achieve efficient plugging of the suction nozzle 312. The sealing ring 354 is fixed in the suction nozzle 312 as a key sealing component to ensure that the gas does not leak from the gap between the suction nozzle 312 and the plugging member 35. The steel ball 353 is located on the side of the sealing ring 354 facing away from the suction cup 32, and is used to tighten the sealing ring 354 under the action of the spring 352 to further enhance the sealing effect.

[0050] On the other hand, this embodiment also provides a washing machine, including the above-mentioned washing machine door with sterilization function.

[0051] Based on the washing machine door with sterilization function of this embodiment, the washing machine of this embodiment has the advantages of being able to achieve global illumination sterilization in the drum, effectively improving the sterilization efficiency and enhancing the sterilization effect.
