Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a dishwasher. Background Art

[0002] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. Fully automatic dishwashers on the market can be divided into two categories: home use and commercial use. Home use fully automatic dishwashers are suitable for families. Commercial dishwashers are commonly used in restaurants, hotels, and canteens of government agencies. Dishwashers can reduce people's labor intensity, improve work efficiency, and promote cleanliness and hygiene.

[0003] Dishwashers usually heat the washing water to sterilize the washing water. Dishwashers usually heat the washing water to a certain temperature (eg 85°C) to inactivate the bacteria, thereby achieving the sterilization effect.

[0004] High-temperature water disinfection can kill some bacteria and viruses, but due to temperature limitations (the maximum temperature of washing water can only reach 100°C), some bacteria or viruses cannot be killed. Utility Model Content

[0005] The present application provides a dishwasher, which is used to solve the problem that the dishwasher in the prior art uses heating washing water for sterilization and disinfection, and this sterilization and disinfection method has the problem of incomplete disinfection.

[0006] The present application provides a dishwasher, comprising a housing, a water-using component, a water storage component and a water delivery pipeline, wherein the water storage component is connected to the housing and is used to store washing water.

[0057] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. Fully automatic dishwashers on the market can be divided into two categories: home use and commercial use. Home use fully automatic dishwashers are suitable for families. Commercial dishwashers are commonly used in restaurants, hotels, and canteens of government agencies. Dishwashers can reduce people's labor intensity, improve work efficiency, and promote cleanliness and hygiene.

[0058] Dishwashers usually heat the washing water to sterilize the washing water. Dishwashers usually heat the washing water to a certain temperature (eg 85°C) to inactivate the bacteria, thereby achieving the sterilization effect.

[0059] High-temperature water disinfection can kill some bacteria and viruses, but due to temperature limitations (the maximum temperature of washing water can only reach 100°C), some bacteria or viruses cannot be killed, and over time it may cause the growth of special bacteria.

[0060] Figure 1 1 is a structural diagram of a dishwasher 1000 provided in an embodiment of the present application. To solve such problems, in a first aspect, an embodiment of the present application provides a dishwasher 1000, such as Figure 1 As shown, the dishwasher 1000 includes a cabinet 10 .

[0061] Figure 2This is one of the partial schematic diagrams of a dishwasher 1000 provided in an embodiment of the present application. Figure 2 As shown, the dishwasher 1000 further includes a water storage member 20, a water delivery pipeline 30 and a light emitting member 40. In addition, the dishwasher 1000 further includes a water using component.

[0062] The water-using component may include a spray assembly for spray washing. Some dishwashers 1000 also have a steam washing function, and the water-using component may also include a steam generator and the like.

[0063] The water storage part 20 may be a water tank or a water cup of a common dishwasher 1000. In addition, the water storage part 20 may also have an object with a storage chamber, such as a common container.

[0064] Figure 3 This is one of the partial cross-sectional views of a dishwasher 1000 provided in an embodiment of the present application. Figure 2 As shown, the water delivery pipeline 30 is connected to the water-using component and the water storage component 20 respectively. Figure 3 As shown, the water delivery pipeline 30 includes a water storage member 20 ( Figure 3 The water in the water pipe 30 is transported to the water delivery channel 311 of the water-using component. The water delivery pipeline 30 can be a common water pipe, etc.

[0065] Figure 4 FIG. 4 is a schematic diagram of a structure of a light emitting element 40 provided in an embodiment of the present application. Figure 4 As shown, the light emitting element 40 is used to emit ultraviolet light. The light emitting element 40 may be an ultraviolet lamp (UV). For example, the light emitting element 40 may be a strong ultraviolet high pressure mercury lamp, a high strength metal halide lamp, a printing plate lamp, a capillary ultra high pressure mercury lamp, a short arc xenon lamp, an excimer discharge lamp, etc. Of course, the ultraviolet lamp may also be of other types.

[0066] Continue as Figure 3 As shown, the water delivery pipeline 30 further includes a mounting hole 321, which is connected to the water delivery channel 311 of the water delivery pipeline 30. The light emitting element 40 is mounted in the mounting hole 321 and is used to emit ultraviolet light toward the water delivery channel 311 so that the ultraviolet light emitted by the light emitting element 40 can enter the water delivery channel 311.

[0067] For example, Figure 2 and Figure 3As shown, the water delivery pipeline 30 may include a main pipeline 31 and a mounting member 32, the mounting member 32 may be located at one side of the main pipeline 31 (in the radial direction) and connected to the peripheral wall of the main pipeline 31, the water delivery channel 311 is provided in the main pipeline 31, the mounting hole 321 is provided in the mounting member 32, and the mounting hole 321 penetrates the peripheral wall of the main pipeline 31 to communicate with the water delivery channel 311. In this way, the main pipeline 31 and / or the mounting member 32 can be specifically repaired.

[0068] Specifically, the mounting member 32 may be a block structure, and the mounting hole 321 may penetrate the peripheral wall of the main pipeline 31, or the peripheral wall of the main pipeline 31 may be provided with an opening, and the ultraviolet light emitted by the light-emitting member 40 may pass through the mounting hole 321 and the opening in sequence and enter the water delivery channel 311. The size of the opening may be smaller than the size of the mounting hole 321.

[0069] Continue as Figure 2 As shown, the dishwasher 1000 may further include a water pump 50, one end of the main pipe 31 may be connected to the water storage component 20, the other end of the main pipe 31 may be connected to the water pump 50, and the water pump 50 is further connected to the water-using component.

[0070] In certain embodiments of the present application, the main pipeline 31 includes a first tube and a second tube connected to each other, one end of the first tube is connected to the water storage member 20 (water cup), and one end of the second tube is connected to the water pump 50.

[0071] In some embodiments of the present application, the first tube is a plastic connecting tube, and the second tube is a rubber connecting tube.

[0072] In some embodiments of the present application, the light emitting member 40 may be disposed on the second tube or the first tube.

[0073] Compared with connecting a sterilizing device to the water delivery pipeline 30, in the above embodiment, the light emitting member 40 is directly arranged on the original connecting pipe, which can simplify the structure and production process while achieving a sterilizing effect.

[0074] The dishwasher 1000 provided in the embodiment of the present application may also include a three-way connection. Figure 2 and Figure 3 As shown, the first connection port of the tee can be connected to the other end of the main pipeline 31, the second connection port of the tee can be connected to the water inlet of the water pump 50, a section of the pipeline with the third connection port on the tee can be used as a mounting part 32, and the internal channel of the pipeline at one end can be used as a mounting hole 321.

[0075] Specifically, the material of the tee can be rubber. Of course, the tee can also be other materials, such as plastic, metal, etc.

[0076] In addition, the material of the main pipe 31 can be plastic. Of course, the material of the main pipe 31 can also be other materials, such as metal, rubber, etc.

[0077] Therefore, the embodiment of the present application provides a dishwasher 1000, including a housing 10, a water-using component, a water storage component 20 and a water delivery pipeline 30, wherein the water storage component 20 is connected to the housing 10 and is used to store washing water. The water delivery pipeline 30 is respectively connected to the water-using component and the water storage component 20, and the water delivery pipeline 30 includes a water delivery channel 311 for delivering water in the water storage component 20 to the water-using component.

[0078] In this way, the water in the water storage member 20 can be transported to the water-using component through the water delivery channel 311 for use by the water-using component.

[0079] The dishwasher 1000 further includes a light emitting member 40 for emitting ultraviolet rays. The water delivery pipeline 30 further includes a mounting hole 321, which is connected to the water delivery channel 311 of the water delivery pipeline 30. The light emitting member 40 is mounted in the mounting hole 321 and is used to emit ultraviolet rays toward the water delivery channel 311, so that the ultraviolet rays emitted by the light emitting member 40 can enter the water delivery channel 311.

[0080] When the dishwasher 1000 washes dishes, the light emitting element 40 is turned on, and the ultraviolet rays can irradiate the washing water in the water delivery channel 311 and sterilize the washing water. In addition, the ultraviolet rays emitted by the light emitting element 40 can kill some bacteria and viruses that high temperature water cannot kill, thereby further improving the sterilization effect.

[0081] In addition, it can be understood that during the process of the dishwasher 1000 washing dishes, the washing water is recycled. In this way, the light-emitting element 40 can continuously sterilize and disinfect the washing water, thereby improving the effect of the dishwasher 1000 in washing dishes.

[0082] In some examples, continue as Figure 3 As shown (in Figure 3 , the light emitting element 40 and the mounting hole 321 are half-section views), the dishwasher 1000 further includes: a light shielding portion 41, which is disposed at the mounting hole 321, and surrounds the light emitting element 40 along the circumference of the mounting hole 321, and is used to block the ultraviolet rays emitted by the light emitting element 40 from propagating toward the wall surface of the mounting hole 321. In this way, the light shielding portion 41 can play a role in preventing light scattering to a certain extent.

[0083] For example, continue as Figure 3 As shown, the light shielding portion 41 can be a section of pipe, and the outer peripheral wall of the pipe is connected to the wall surface of the mounting hole 321. Figure 3 As shown, the light shielding portion 41 may be in the shape of a cylinder.

[0084] Figure 5 This is a second partial cross-sectional view of a dishwasher 1000 provided in an embodiment of the present application. Figure 5 As shown, the shape of the shading portion 41 can be conical, and the bottom surface of the cone can face the water delivery channel 311. Accordingly, the shape of the mounting hole 321 can be set to match the shape of the shading portion 41. In addition, the shape of the light emitting element 40 can also be set to match the shape of the shading portion 41. Figure 5 The following are for illustration only.

[0085] In this way, the light emitted by the light emitting element 40 can be diverged within a certain angle range, so that it can illuminate a wider range of washing water to improve the sterilization and disinfection effect.

[0086] Figure 6 This is a third partial cross-sectional view of a dishwasher 1000 provided in an embodiment of the present application. Figure 6 As shown, the shape of the shading portion 41 can also be a truncated cone, and accordingly, the shape of the mounting hole 321 can be set to match the shape of the shading portion 41. In addition, the shape of the light emitting element 40 can also be set to match the shape of the shading portion 41. Figure 6 The beneficial effects can be referred to the beneficial effects of the above-mentioned shading portion 41 being in a conical shape, and the embodiments of the present application will not be elaborated on this.

[0087] Among them, continue as Figure 6 As shown, when the light shielding portion 41 is in the shape of a truncated cone, the bottom surface of the truncated cone with a larger area can face the water conveying channel 311.

[0088] Figure 7 FIG4 is a partial cross-sectional view of a dishwasher 1000 provided in an embodiment of the present application. Figure 7 As shown, when the light shielding portion 41 is in the shape of a truncated cone, the bottom surface of the truncated cone with a smaller area may face the water conveying channel 311 .

[0089] Exemplarily, the material of the light shielding portion 41 may be opaque plastic. The material of the light shielding portion 41 may also be other opaque materials, such as metal, ceramic, cloth, etc.

[0090] In addition, when the material of the tee is rubber, the light shielding portion 41 can block ultraviolet rays from reaching the rubber, thereby reducing the exposure of the rubber to ultraviolet rays, which can increase the service life of the rubber.

[0091] Figure 8 FIG5 is a partial cross-sectional view of a dishwasher 1000 provided in an embodiment of the present application. In some examples, such as Figure 8As shown, the dishwasher 1000 further includes a light-transmitting portion 42 , which is disposed on one side of the light-emitting element 40 along a direction from the mounting hole 321 to the water delivery channel 311 , and is used to transmit ultraviolet rays emitted by the light-emitting element 40 .

[0092] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the wall surface of the light-transmitting portion 42 away from the light-emitting element 40 is a plane. This can play a role in gathering light to a certain extent. Or,

[0093] Fig. 9 FIG6 is a partial cross-sectional view of a dishwasher 1000 provided in an embodiment of the present application. Fig. 9 As shown, the wall surface of the light-transmitting portion 42 away from the light-emitting element 40 can be a concave arc surface. The light passing through the concave arc surface is divergent, so that a larger range of washing water can be sterilized. Or,

[0094] Fig.10 This is a second structural diagram of a light emitting element 40 provided in an embodiment of the present application. Fig. 9 and Fig.10 It can be understood that the wall surface of the light-transmitting portion 42 away from the light-emitting element 40 (that is, the wall surface at the bottom of the light-transmitting portion 42) is a convex arc surface, and the light-emitting element 40 is located inside the light-transmitting portion 42. Fig.10 The focusing effect of light passing through the convex curved surface is stronger, so a certain position can be sterilized intensively.

[0095] For example, continue as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in FIG. 1 , the wall surface of the light-transmitting portion 42 away from the light-emitting element 40 may be a plane. Fig. 9 As shown, the wall surface of the light-transmitting portion 42 away from the light-emitting element 40 may be a concave arc surface. Fig.10 As shown, the wall surface of the light-transmitting portion 42 away from the light-emitting element 40 may be a concave arc surface.

[0096] It is understandable that the light-transmitting portion 42 is transparent. Exemplarily, the material of the light-transmitting portion 42 may be glass, such as quartz glass, etc. Exemplarily, the material of the light-transmitting portion 42 may also be polymethyl methacrylate (PMMA). The material of the light-transmitting portion 42 may also be polycarbonate (PC), etc. The light-transmitting portion 42 may also be other transparent materials.

[0097] In addition, continue as Figure 8As shown, along the direction from the mounting hole 321 to the water delivery channel 311 (i.e. Figure 8 The light-transmitting portion 42 may be located at one side of the light-shielding portion 41. For example, the light-transmitting portion 42 may be located at the end of the light-shielding portion 41. Figure 8 The position of the light-transmitting portion 42 may also be at a certain distance from the end of the light-shielding portion 41 facing the Y-axis direction, that is, the light-transmitting portion 42 may also be provided on one side of the light-transmitting portion 42 facing the Y-axis direction.

[0098] Furthermore, when the material of the mounting member 32 is rubber, continue as follows Figure 8 As shown, along the direction from the mounting hole 321 to the water delivery channel 311, part of the light-transmitting portion 42 can extend into the water delivery channel 311. This can reduce the light transmitted by the light-transmitting portion 42 from reaching the rubber (when the material of the tee is rubber), thereby increasing the service life of the rubber.

[0099] For example, refer to Figure 3 and Figure 8 , along the direction from the mounting hole 321 to the water delivery channel 311, the size of the portion of the light-transmitting portion 42 extending into the water delivery channel 311 can be smaller than the size (or thickness) of the light-transmitting portion 42. In this way, the portion of the light-transmitting portion 42 extending into the water delivery channel 311 can be reduced, thereby reducing the obstruction of the light-transmitting portion 42 to the flow of washing water.

[0100] Furthermore, in some embodiments of the present application, the light-transmitting portion 42 can be completely located in the mounting hole 321 (because the light-shielding portion 41 can block ultraviolet rays from reaching the rubber tee), and this can minimize the obstruction of the light-transmitting portion 42 on the flow of washing water. The light-transmitting portion 42 can also be completely extended into the water delivery channel 311.

[0101] Fig.11 FIG. 7 is a partial cross-sectional view of a dishwasher 1000 provided in an embodiment of the present application. In some examples, such as Fig.11 As shown, the dishwasher 1000 further includes a mounting bracket 60 and a lamp cover 70, and the mounting bracket 60 is disposed in the mounting hole 321. Fig.11 As shown, the lampshade 70 is connected to the mounting bracket 60, and a light emitting cavity 71 is formed between the lampshade 70 and the mounting bracket 60. Fig.11 As shown, the light emitting member 40 is connected to the mounting bracket 60 and is located in the light emitting cavity 71 .

[0102] The light emitting element 40 is located in the light emitting cavity 71 , which can prevent the light emitting element 40 from being stained by water, thereby reducing the risk of the light emitting element 40 malfunctioning due to the influence of water.

[0103] The mounting bracket 60 may be a housing of the ultraviolet lamp. Fig.11 As shown, the mounting bracket 60 may be formed with a groove, and the lamp cover 70 may cover the notch of the groove so that the space in the groove forms a light-emitting cavity 71 .

[0104] Exemplarily, both the mounting bracket 60 and the lamp cover 70 may be formed with grooves, and the notches of the two grooves are connected so that the spaces within the two grooves form a light emitting cavity 71 .

[0105] Exemplarily, the lampshade 70 may form a groove, and the mounting bracket 60 has a wall surface, which may cover the notch of the groove, so that the space in the groove forms a light-emitting cavity 71 .

[0106] In some examples, continue as Fig.11 As shown, the mounting bracket 60 includes a shading portion 41, and the lampshade 70 includes a connecting portion 72 and a light-transmitting portion 42, wherein the connecting portion 72 is connected to the mounting bracket 60 and is located at the inner circumference of the shading portion 41, and the shading portion 41 is connected to the connecting portion 72. In this way, the lampshade 70 can be connected to the mounting bracket 60.

[0107] For example, the connection portion 72 can be snap-fitted with the mounting bracket 60. The snap-fitting connection is detachable, so that the connection portion 72 can be easily removed to remove the lampshade 70, thereby repairing the lampshade 70 or the light-emitting element 40. Fig.11 As shown, the connecting portion 72 may be a protrusion, and a slot may be provided on the mounting bracket 60, and the protrusion may be inserted into the slot.

[0108] For example, continue as Fig.11 As shown, the mounting bracket 60 is provided with an annular recessed portion 61, and the annular recessed portion 61 is directed from the water delivery channel 311 to the mounting hole 321 (i.e. Fig.11 The direction opposite to the Y axis is concave. Fig.11 As shown, the connecting portion 72 may surround the light emitting member 40 and extend into the annular recessed portion 61. The connecting portion 72 may be sealedly connected to at least one peripheral wall surface of the annular recessed portion 61.

[0109] The peripheral wall surface of the connecting portion 72 contacts the peripheral wall surface of the annular recessed portion 61, so that the connection area between the connecting portion 72 and the annular recessed portion 61 is large, thereby enhancing the connection strength between the connecting portion 72 and the light emitting member 40. The connecting portion 72 is sealedly connected to at least one peripheral wall surface of the annular recessed portion 61, so that a certain sealing performance can be ensured, thereby improving the working stability of the light emitting member 40.

[0110] The connection portion 72 is sealed to the peripheral wall of the annular groove. Fig.11 The connecting portion 72 may be interference fit with the annular recessed portion 61. The peripheral wall surface on one side of the connecting portion 72 may abut against one peripheral wall surface of the annular recessed portion 61 correspondingly.

[0111] Alternatively, the peripheral wall surface on the other side of the connecting portion 72 may correspondingly abut against another peripheral wall surface of the annular recessed portion 61 .

[0112] Or, continue as Fig.11 As shown, the peripheral wall surface on one side of the connecting portion 72 can correspondingly abut against one peripheral wall surface of the annular recessed portion 61 , and the peripheral wall surface on the other side of the connecting portion 72 can correspondingly abut against another peripheral wall surface of the annular recessed portion 61 .

[0113] In the above three situations, the connection portion 72 can be sealed and connected to the peripheral wall surface of the annular recessed portion 61 .

[0114] In addition, in the embodiment of the present application, a sealant may be used to seal the connection portion 72 and at least one peripheral wall surface of the annular recessed portion 61. In this way, the sealing performance may be enhanced.

[0115] Continue as Fig.11 As shown, the recessed direction of the annular recessed portion 61 may be parallel to the depth direction of the mounting hole 321. Of course, the recessed direction of the annular recessed portion 61 may also form a certain angle with the depth direction of the mounting hole 321. Accordingly, the connecting portion 72 may be in a shape matching the annular recessed portion 61.

[0116] Alternatively, the connecting portion 72 may be formed with an annular recessed portion 61, and the mounting bracket 60 may be formed with an annular clamping wall, the shape of which may match the shape of the annular recessed portion 61. The annular clamping wall may extend into the annular recessed portion 61. The annular clamping wall may be sealingly connected to at least one peripheral wall surface of the annular recessed portion 61.

[0117] For example, the connection portion 72 may be threadedly connected to the mounting bracket 60. The threaded connection is detachable, so that the connection portion 72 may be easily disassembled to disassemble the lampshade 70, thereby repairing the lampshade 70 or the light-emitting element 40.

[0118] Specifically, the mounting bracket 60 may be formed with an annular groove, the connecting portion 72 may surround the light emitting member 40 (may be the peripheral wall of the groove formed on the lampshade 70), and the connecting portion 72 may extend into the annular groove. At least one side of the peripheral wall of the connecting portion 72 may be provided with a thread, and a peripheral wall of the annular groove may also be provided with a thread, and the thread on the peripheral wall of the connecting portion 72 is threadedly connected with the thread on the peripheral wall of the annular groove.

[0119] In this way, the connection portion 72 can be threadedly connected to the mounting bracket 60. In addition, this connection method can also ensure a certain degree of sealing, thereby ensuring the stability of the operation of the light-emitting element 40.

[0120] Of course, the connection portion 72 can also be threadedly connected to the mounting bracket 60 in other ways. For example, the connection portion 72 can be connected to the mounting bracket 60 by bolts, screws, studs, nuts, etc.
