For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0038] Refer to the following Figures 1 to 6 The present invention describes an ultraviolet sterilization module and a dishwasher according to some embodiments of the present application.

[0039] This application provides a UV sterilization module, such as Figure 1 、 Figure 3 and Figure 4As shown, the ultraviolet sterilization module includes an ultraviolet lamp 1, which includes an inner tube 12, an outer tube 11 and a fixing member 13. One end of the outer tube 11 is an open end. The outer tube 11 is sleeved on the outside of the inner tube 12, and a cavity 15 is formed between the outer tube 11 and the inner tube 12. The fixing member 13 is inserted between the outer tube 11 and the inner tube 12 to fix the inner tube 12 to the inner side of the outer tube 11 through the fixing member 13; the fixing member 13 is formed with a notch 14, so that the cavity 15 between the inner tube 12 and the outer tube 11 can be opened. The notch 14 on the fixing member 13 can maintain air circulation with the outside world, thereby reducing the working temperature of the ultraviolet lamp 1 over a certain length and increasing the service life of the ultraviolet lamp 1. At the same time, silicon elements will precipitate from the ultraviolet lamp 1 during long-term use, and the precipitated silicon elements can flow out through the notch 14 on the fixing member 13, thereby avoiding the accumulation of silicon elements in the cavity 15 and causing the ultraviolet lamp 1 to produce a white fog effect, so that the ultraviolet lamp 1 can still maintain good ultraviolet irradiance after long-term use.

[0040] In this embodiment, preferably, Figure 3 As shown, the fixing member 13 includes a ring body and a plurality of arms. The ring body is adaptively sleeved on the inner tube 12. The plurality of arms are arranged at intervals in the circumferential direction around the fixing member 13. One end of the plurality of arms is connected to the ring body, and the other end of the plurality of arms is abutted against the inner wall of the outside. The above-mentioned gap 14 is formed between two adjacent arms, so that the fixing member 13 has multiple gaps 14 to ensure that the cavity 15 maintains smooth communication with the outside air.

[0041] In this embodiment, preferably, the fixing member 13 and the plurality of supporting arms are integrally formed.

[0042] In this embodiment, preferably, the fixing member 13 is made of rubber, so that the fixing member 13 is elastic and can be inserted between the inner tube 12 and the outer tube 11 in an interference fit manner, thereby stably installing the inner tube 12 inside the inner tube 12.

[0043] In one embodiment of the present application, preferably, the other end of the outer tube 11 relative to its own open end is a closed end. Specifically, when in use, the open end of the outer tube 11 faces upward and the closed end of the outer tube 11 faces downward; both ends of the inner tube 12 are provided with wiring harnesses, and the wiring harness at the lower end of the inner tube 12 is routed through the cavity 15 between the outer tube 11 and the inner tube 12 to the upper end of the inner tube 12 and merged with the wiring harness at the upper end of the inner tube 12, so that the wiring harnesses at the upper and lower ends of the inner tube 12 are merged and extend out of the outer tube 11.

[0044] In one embodiment of the present application, preferably, Figure 1 and Figure 2As shown, the outer cover of the ultraviolet lamp 1 is provided with a lampshade 2, the middle part of the lampshade 2 is a light-transmitting area with a light-transmitting hole, and the areas on both sides of the light-transmitting area are fully covered areas 23 without light-transmitting holes; when the ultraviolet lamp 1 is in use, the middle part of the ultraviolet lamp 1 is the luminous area, and the two ends of the ultraviolet lamp 1 are non-light-emitting areas. When the lampshade 2 is covered on the outside of the ultraviolet lamp 1, the light-transmitting area in the middle of the lampshade 2 is opposite to the light-emitting area in the middle of the ultraviolet lamp 1, so that the light emitted by the ultraviolet lamp 1 can be radiated through the light-transmitting holes in the light-transmitting area, and the non-luminous areas at both ends of the ultraviolet lamp 1 are opposite to the fully covered areas 23 at both ends of the lampshade 2, so that the non-luminous areas of the ultraviolet lamp 1 are hidden by the lampshade 2 to improve the overall aesthetics.

[0045] In this embodiment, preferably, Figure 2 As shown, the light-transmitting area in the middle of the lampshade 2 includes a first light-transmitting area 21 and two second light-transmitting areas 22. The two second light-transmitting areas 22 are located on both sides of the first light-transmitting area 21. That is, the second light-transmitting areas 22 are located between the first light-transmitting area 21 and the fully covered areas 23 on both sides. The first light-transmitting area 21 and the second light-transmitting area 22 are each provided with a plurality of light-transmitting holes, and the light-transmitting holes in the second light-transmitting area 22 are smaller and more densely packed than the light-transmitting holes in the first light-transmitting area 21.

[0046] After the ultraviolet lamp 1 has been running for a long time, the surface material of the filament gradually evaporates and condenses on the surface of the lamp tube. Black areas will form at the beginning and end of the luminous area of ​​the ultraviolet lamp 1 because they are close to the filament. The two second light-transmitting areas 22 of the lampshade 2 are opposite to the two black areas of the luminous area of ​​the ultraviolet lamp 1, and the first light-transmitting area 21 is opposite to the luminous area of ​​the ultraviolet lamp 1 between the two black areas.

[0047] Therefore, while the lampshade 2 provides good protection for the ultraviolet lamp 1, it ensures the high transmittance of the ultraviolet light source by opening the first light-transmitting area 21 with large light-transmitting holes, and the blackened area can also emit light and have a sterilization effect. The second light-transmitting area 22 with dense small light-transmitting holes can ensure the transmittance of the ultraviolet light source in the blackened area, while also reducing the possibility of the blackened area being seen by the user.

[0048] In one embodiment of the present application, preferably, Figure 1 As shown, both ends of the ultraviolet lamp 1 in the longitudinal direction are provided with mounting seats, namely the first mounting seat 3 and the second mounting seat 4. When the ultraviolet lamp 1 is used in a dishwasher, the ultraviolet lamp 1 is fixedly mounted on the inner tank side wall 5 of the dishwasher through the two mounting seats; the two ends of the lampshade 2 of the ultraviolet lamp 1 in the longitudinal direction are also correspondingly clamped on the two mounting seats, so that the lampshade 2 can be stably covered on the outside of the ultraviolet lamp 1, and the two mounting seats are both covered on the inner side of the lampshade 2 for concealment, thereby ensuring the overall aesthetics of the ultraviolet sterilization module.

[0049] Regarding the clamping connection between the two mounting bases and the lampshade 2 , the clamping structures between the two mounting bases and the lampshade 2 are the same, and the clamping connection between the mounting base at one end and the lampshade 2 is taken as an example for description.

[0050] like Figure 1 The lampshade 2 includes two side portions, which are arranged opposite to each other in the radial direction of the ultraviolet lamp 1. The ultraviolet lamp 1 is located between the two side portions. A card interface 24 is provided on each side portion. The mounting base is provided with claws 31 on both sides of the radial direction of the ultraviolet lamp 1, that is, one claw 31 is located on the same side as one side portion of the lampshade 2, and the other claw 31 is located on the same side as the other side portion of the lampshade 2, and the two claws 31 are respectively clamped in the card interface 24 of the side portion on the same side, so that the lampshade 2 is clamped on the mounting base.

[0051] Pins 25 are respectively provided on the two side portions, and pin holes 32 are respectively provided on both sides of the radial direction of the ultraviolet lamp 1 on the mounting base. The pins 25 on the two sides can be respectively inserted into the pin holes 32 on the same side, so that the two side portions will not be deformed in the direction away from each other through the cooperation between the pins 25 and the pin holes 32, thereby ensuring that the claws 31 on the mounting base will not be detached from the buckles in the side portions, thereby ensuring the stability of the lampshade 2 being clamped on the mounting base.

[0052] Regarding the connection between the two mounting seats and the ultraviolet lamp 1, and the connection between the two mounting seats and the inner tank side wall 5 of the dishwasher, for the sake of easy distinction, one mounting seat is defined as the first mounting seat 3, and the other mounting seat is positioned as the second mounting seat 4.

[0053] Among them, such as Figure 1 、 Figure 4 and Figure 5 As shown, a slot 33 is formed on one side of the first mounting base 3. The slot 33 has a notch at one end and a top wall at the other end. A first wire-passing hole 36 is also formed on the first mounting base 3. One end of the first wire-passing hole 36 extends through the top wall of the slot 33, and the other end extends through the side of the first mounting base 3 facing away from the slot 33. The open end of the outer tube 11 faces the first mounting base 3, and the outer tube 11 is sealedly inserted into the slot 33. For example, when the open end of the outer tube 11 is inserted into the slot 33, a sealant layer is filled between the inner wall of the slot 33 and the outer wall of the outer tube 11. This sealant layer stably and firmly bonds the outer tube 11 to the slot 33, ensuring a tight seal between the outer tube 11 and the slot 33, preventing liquid in the dishwasher from entering the outer tube 11. Simultaneously, the power cord on the inner tube 12 is led out of the first mounting base 3 through the first wire-passing hole 36. At the same time, the cavity 15 between the outer tube 11 and the inner tube 12 is connected to the first wire hole 36, so that the cavity 15 is connected to the external environment through the first wire hole 36, thereby helping to dissipate heat and silicon, so as to improve the service life of the ultraviolet lamp 1 and ensure that the ultraviolet lamp 1 still has good ultraviolet irradiance after long-term use.

[0054] In this embodiment, preferably, an expansion section 35 with a larger diameter is formed at one end of the slot 33 facing its own notch, and the sealant layer is filled between the expansion section 35 and the circumferential side wall of the outer tube 11; by providing the expansion section 35, it can be ensured that the sealant layer is effectively filled between the inner wall of the slot 33 and the circumferential side wall of the outer tube 11, so as to ensure good sealing between the slot 33 and the outer tube 11 while achieving stable installation.

[0055] like Figure 1 and Figure 5 As shown, the closed end of the outer tube 11 faces the second mounting seat 4, and a first limiting portion 41 and a second limiting portion 42 are provided on one side of the second mounting seat 4, wherein the first limiting portion 41 forms a limited space, and the outer tube 11 can be just inserted into the limited space of the first limiting portion 41; at the same time, the end of the closed end of the outer tube 11 can abut against the second limiting portion 42, thereby realizing the limited installation of the outer tube 11 of the ultraviolet lamp 1 on the second mounting seat 4.

[0056] In this embodiment, preferably, Figure 5 As shown, the sides of the two mounting bases facing away from the UV lamp 1 are both facing the inner side wall 5 of the dishwasher and are firmly connected to the inner side wall 5 .

[0057] Among them, a second wire passing hole is opened at a position opposite to the first wire passing hole on the inner tank side wall 5 and the first mounting seat 3. The power cord of the inner tube 12 of the ultraviolet lamp 1 can extend to the outside of the inner tank side wall 5 through the second wire passing hole for electrical connection; at the same time, a first sealing surface is formed around the first wire passing hole on the side of the first mounting seat 3 facing the inner tank side wall 5. The first sealing surface is sealed against the inner tank side wall 5 through the sealing gasket 6, thereby preventing the liquid in the dishwasher from leaking out of the inner tank side wall 5 or flowing into the first mounting seat 3 and entering the ultraviolet lamp 1.

[0058] A limiting boss 43 is provided on the side of the second mounting base 4 facing the inner sidewall 5. A limiting hole is defined in the inner sidewall 5 at a position opposite the limiting boss 43. The limiting boss 43 fits snugly within the limiting hole, thereby limiting the position of the second mounting base 4 on the inner sidewall 5. A second sealing surface is formed around the limiting boss 43 on the side of the second mounting base 4 facing the inner sidewall 5. This second sealing surface also seals against the inner sidewall 5 via a sealing gasket 6, thereby preventing liquid from leaking out of the inner sidewall 5 through the limiting hole.

[0059] Preferably, if Figure 5 and Figure 6 As shown, a pressure ring 34 is formed around the first sealing surface, so that when the first sealing surface is pressed against the corresponding sealing gasket 6, the pressure ring 34 can enhance the compression of the sealing gasket 6 to improve the sealing effect.

[0060] A pressure ring 34 is also formed on the second seal surrounding the second sealing surface. Its function is the same as that of the pressure ring 34 on the first sealing surface, and will not be repeated here.

[0061] The present application also provides a dishwasher comprising the ultraviolet sterilization module of any of the above embodiments.

[0062] In this embodiment, the dishwasher includes an ultraviolet sterilization module, so the dishwasher has all the beneficial effects of the ultraviolet sterilization module, which will not be described in detail here.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
