Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] This application provides a dishwasher, which is a device that automatically cleans tableware such as bowls, chopsticks, plates, and knives. Dishwashers can be of various types; exemplary dishwashers include built-in dishwashers, countertop dishwashers, and sink-type dishwashers. Built-in dishwashers are typically installed in cabinets; countertop dishwashers are placed directly on the kitchen countertop; and sink-type dishwashers are installed directly next to the sink. This application does not specifically limit the type of dishwasher.

[0026] Furthermore, the dishwasher's operation typically includes a pre-wash, a washing, a rinsing, and a drying process. Specifically, the pre-wash refers to rinsing the dishes with water before the actual washing cycle to remove large food residues. However, not all dishwashers include a pre-wash; users can skip this step to save washing time. The washing cycle involves the dishwasher spraying high-temperature, high-pressure water with a specialized detergent to thoroughly clean the dishes. The rinsing cycle involves rinsing the dishes with clean water to remove any remaining detergent. The drying cycle typically involves drying the dishes after washing using heated air or residual heat.

[0027] During or after the dishwasher washes the tableware, it needs to be sterilized to ensure hygiene. However, in related technologies, dishwashers mainly use high-temperature hot water or chemical disinfectants to sterilize the tableware. This limits the types of tableware that can be sterilized and is not thorough enough, resulting in insufficient sterilization capabilities of the dishwasher.

[0028] Therefore, to resolve the above issues, please refer to [link / reference]. Figures 1-2 In this embodiment of the application, a steam sterilization device 20 and an ultraviolet sterilization device 30 are set up to perform dual sterilization on the tableware in the dishwasher 1, so as to improve the sterilization ability of the dishwasher 1.

[0029] Please continue reading. Figures 1-2 Specifically, the dishwasher 1 may include an inner tub 10, and the inner tub 10 has a washing cavity 11. It is understood that the washing cavity 11 is the main space for the dishwasher 1 to perform washing operations. The washing cavity 11 can accommodate a dish rack and is equipped with a spray arm. That is, a slide rail is installed on the cavity wall of the washing cavity 11, and the dish rack is equipped with rollers. The slide rail and rollers cooperate with each other to facilitate the user pushing and pulling the dish rack, thereby facilitating the placement or removal of tableware into or out of the washing cavity 11. Of course, the dish rack can also cooperate with the cavity wall of the washing cavity 11 in other ways to achieve the placement and removal of tableware; this embodiment does not specifically limit this. A spray arm is provided in the washing cavity 11 so that the water or detergent needed by the dishwasher 1 during the washing process can be sprayed out through the spray arm, thereby achieving the cleaning of the tableware.

[0030] It should be noted that the material used to make the inner liner 10 is not specifically limited in this application embodiment. For example, the material used to make the inner liner 10 can be at least one of stainless steel and plastic.

[0031] Furthermore, the steam sterilization device 20 is connected to the washing cavity 11. Thus, when the steam sterilization device 20 is working, it can spray steam into the washing cavity 11. The sterilization effect of the high-temperature steam mainly relies on the high temperature to destroy the cell structure of microorganisms, thereby achieving the sterilization effect. That is, the steam sterilization device can generate high-temperature steam when it is working. Since this high-temperature steam can effectively kill bacteria, viruses and other harmful microorganisms, when the high-temperature steam is sprayed into the washing cavity 11, it can sterilize the tableware located in the washing cavity 11.

[0032] The ultraviolet (UV) sterilization device 30 is mounted on the wall of the washing cavity 11; that is, the UV sterilization device 30 can be installed on the wall of the washing cavity 11 by means of snap-fit, magnetic attraction, welding, or screw connection. The UV sterilization device 30 mainly works by emitting ultraviolet rays of a specific wavelength. These ultraviolet rays can destroy the structure of bacteria, rendering them unable to reproduce, thereby achieving sterilization. In other words, when the UV sterilization device 30 is working, it emits ultraviolet rays into the washing cavity 11 to sterilize the tableware inside. Furthermore, the dishwasher 1 consumes less energy using the UV sterilization device 30, making it more energy-efficient.

[0033] This embodiment of the application provides a steam sterilization device 20 and an ultraviolet sterilization device 30. When the steam sterilization device 20 and the ultraviolet sterilization device 30 work simultaneously, they can perform dual sterilization on the tableware located in the washing cavity 11, thereby improving the sterilization capability of the dishwasher 1. In addition, since the steam sterilization device 20 and the ultraviolet sterilization device 30 have low requirements on the material type of the tableware, they can sterilize tableware of various materials, thereby broadening the range of tableware materials that the dishwasher 1 can sterilize.

[0034] Furthermore, since the steam sterilization device 20 can sterilize the tableware in the washing cavity 11 by spraying steam, and the ultraviolet sterilization device 30 does not produce any harmful substances during the sterilization process and does not pollute the environment; therefore, the combined use of the steam sterilization device 20 and the ultraviolet sterilization device 30 can improve the safety of the dishwasher 1 in sterilizing tableware.

[0035] In some embodiments, the dishwasher 1 further includes a controller electrically connected to both the steam sterilization device 20 and the ultraviolet sterilization device 30 to control their operation. It is understood that when the dishwasher 1 needs to sterilize the tableware, the controller sends signals to the steam sterilization device 20 and the ultraviolet sterilization device 30 to activate them, thereby providing comprehensive cleaning and sterilization functions for the tableware. It should be noted that the type of controller is not specifically limited in this application embodiment.

[0036] In addition, the controller can be used in conjunction with the control panel of the dishwasher 1 or the user's mobile phone. In this way, the user can select at least one of steam sterilization and ultraviolet sterilization for the tableware by operating the control panel or mobile phone. At the same time, the user can time the sterilization and cleaning functions of the dishwasher 1 by operating the control panel or mobile phone to meet the diverse needs of the user.

[0037] Please continue reading. Figures 1-2 In some embodiments, the inner liner 10 includes an upper inner liner 12, a lower inner liner 13, and a partition plate 14.

[0038] Specifically, the upper inner tank 12 has an upper washing chamber 111; the lower inner tank 13 has a lower washing chamber 112, and the lower inner tank 13 is located below the upper inner tank 12; a partition plate 14 is disposed inside the inner tank 10 to separate the upper inner tank 12 and the lower inner tank 13, so that the upper inner tank 12 forms the upper washing chamber 111 and the lower inner tank 13 forms the lower washing chamber 112. It is understood that the upper inner tank 12 and the lower inner tank 13 do not affect each other due to the partition plate 14; for example, clean tableware can be placed in the upper inner tank 12, and tableware that needs to be washed can be placed in the lower inner tank 13, and when the lower inner tank 13 washes the tableware, the water required for washing will not spray onto the upper inner tank 12; or when the upper inner tank 12 and the lower inner tank 13 wash the tableware at the same time, the dishwasher 1 can set different washing intensities and washing times for the upper inner tank 12 and the lower inner tank 13 according to the degree of soiling of the tableware, so as to achieve the desired cleaning effect. Of course, in some embodiments, the space of the upper washing chamber 111 of the upper inner liner 12 is smaller than the space of the lower washing chamber 112 of the lower inner liner 13. In this way, when the user washes fewer dishes, the user can choose to start only the upper inner liner 12, and the energy consumption of the dishwasher 1 is saved because the space of the upper washing chamber 111 is smaller.

[0039] Furthermore, this application embodiment does not specifically limit the arrangement of the steam sterilization device 20 and the ultraviolet sterilization device 30 in the upper washing chamber 111 and the lower washing chamber 112. Exemplarily, one of the upper washing chamber 111 or the lower washing chamber 112 may be equipped with both the steam sterilization device 20 and the ultraviolet sterilization device 30; that is, only the upper washing chamber 111 may be equipped with both the steam sterilization device 20 and the ultraviolet sterilization device 30; or, only the lower washing chamber 112 may be equipped with both the steam sterilization device 20 and the ultraviolet sterilization device 30. Exemplarily, at least one of the steam sterilization device 20 and the ultraviolet sterilization device 30 may be equipped in both the upper washing chamber 111 and the lower washing chamber 112; that is, the upper washing chamber 111 may be equipped with at least one of the steam sterilization device 20 and the ultraviolet sterilization device 30, and the lower washing chamber 112 may be equipped with at least one of the steam sterilization device 20 and the ultraviolet sterilization device 30. For example, the upper washing chamber 111 and the lower washing chamber 112 share a set of steam sterilization device 20 and ultraviolet sterilization device 30.

[0040] It should be noted that the material used to make the partition plate 14 is not specifically limited in this embodiment. Common materials include stainless steel, plastic, ceramic, etc., to ensure the durability and corrosion resistance of the partition plate 14. Of course, the form in which the partition plate 14 is installed in the inner liner 10 is not specifically limited in this embodiment. Exemplarily, the partition plate 14 and the lower inner liner 13 are integral components; that is, the partition plate 14 and the lower inner liner 13 can be injection molded into one piece. This reduces the assembly steps of the dishwasher 1 and improves the sealing between the upper washing chamber 111 and the lower washing chamber 112.

[0041] For example, the partition plate 14 is a separate component from the inner tub 10, and the partition plate 14 is installed on the cavity wall of the washing cavity 11 to divide the washing cavity 11 into an upper washing cavity 111 and a lower washing cavity 112. That is, the partition plate 14 can be installed on the cavity wall of the washing cavity 11 by means of snap-fit, screw-fit, magnetic attraction, etc. When the partition plate 14 is damaged, only the partition plate 14 needs to be replaced, thereby saving the replacement cost of the dishwasher 1. In addition, when the partition plate 14 is detachably connected to the cavity wall of the washing cavity 11, the user can move the partition plate 14 so that the upper washing cavity 111 and the lower washing cavity 112 can form cavities of different or the same size, thus improving the adaptability of the dishwasher 1.

[0042] In some other embodiments, since the partition plate 14 divides the inner liner 10 into an upper inner liner 12 and a lower inner liner 13, when the upper washing chamber 111 and the lower washing chamber 112 are equipped with at least one of a steam sterilization device 20 and an ultraviolet sterilization device 30, the user can flexibly choose steam sterilization, ultraviolet sterilization, or simultaneous steam sterilization and ultraviolet sterilization according to the material of the tableware and the sterilization requirements. In this way, not only is sterilization of the tableware achieved, but protection of the tableware is also taken into account.

[0043] In some embodiments, the steam sterilization device 20 includes a steam generator disposed outside the inner tank 10. It is understood that the working principle of the steam generator is primarily based on the conversion of thermal energy and the phase change process of water; specifically, the steam generator generates heat energy through electrical energy, which is transferred to the liquid inside the steam generator through radiation and convection. When the liquid absorbs sufficient heat, its temperature gradually rises, eventually reaching its boiling point, thereby generating steam. Distributing the steam generator outside the inner tank 10 ensures sufficient space for efficient cleaning operations and facilitates inspection and maintenance of the steam generator, reducing safety risks.

[0044] Please see Figure 1 as well as Figure 3 Furthermore, the partition plate 14 has a steam nozzle 21, which is connected to a steam generator and is also connected to at least one of the upper washing chamber 111 and the lower washing chamber 112. That is, the steam generated by the steam generator needs to be connected to the steam nozzle 21 through a pipe so that the steam can be delivered to the steam nozzle 21 and sprayed out from the steam nozzle 21 to at least one of the upper washing chamber 111 and the lower washing chamber 112. In this way, the tableware can be effectively sterilized.

[0045] It should be noted that the embodiment of this application does not specifically limit the arrangement of the steam nozzles 21. For example, the steam nozzles 21 can be evenly arranged on the partition plate 14, so that no matter how the dish rack is arranged, the steam can be evenly and fully covered to every space of the upper washing chamber 111 and the lower washing chamber 112, thereby effectively sterilizing the tableware.

[0046] Please see Figure 3 For example, the steam nozzles 21 can be arranged on the left and right sides of the partition plate 14; that is, the steam nozzles 21 are set on the left and right sides of the partition plate 14, and the position of the steam nozzles 21 should correspond to the position of the bowl basket, so as to ensure that the steam ejected from the steam nozzles 21 can be accurately sprayed onto the tableware on the bowl basket.

[0047] For example, when the steam nozzle 21 is connected to the upper washing chamber 111, the steam nozzle 21 needs to be set towards the center of the upper washing chamber 111 so that the steam ejected from the steam nozzle 21 can be sprayed towards the center of the upper washing chamber 111 to achieve sterilization of the tableware.

[0048] For example, when the steam nozzle 21 is connected to the lower washing chamber 112, the steam nozzle 21 needs to be set towards the center of the lower washing chamber 112 so that the steam ejected from the steam nozzle 21 can be sprayed towards the center of the lower washing chamber 112 to achieve sterilization of the tableware.

[0049] In this embodiment, the placement of the steam nozzle 21 on the partition plate 14 also needs to be considered in conjunction with the steam diffusion rate and pressure to achieve the best effect of steam sterilization on tableware.

[0050] In addition, in order to achieve the recycling of steam, the dishwasher 1 of this application embodiment may also include a steam recovery device. In this way, after the steam has sterilized the tableware, the steam recovery device can recover and condense the steam so that the recovered steam can be used to preheat the water inlet or for other purposes, thereby reducing energy consumption.

[0051] Please see Figure 4 In some embodiments, the dishwasher 1 further includes a base 40, which is disposed below the inner tub 10, and the base 40 and the inner tub 10 form an installation cavity 41. That is, the base 40 can be connected to the inner tub 10 by means of screws, snap-fits, etc., and the base 40 serves to support the inner tub 10 so that the inner tub 10 remains stable and balanced during operation of the dishwasher 1. In addition, the base 40 is usually made of plastic or other lightweight materials to reduce the overall weight of the dishwasher 1, thereby improving the ease of handling the dishwasher 1; of course, the material of the base 40 also needs to have strength and rigidity so that the base 40 can support the inner tub 10.

[0052] Furthermore, the mounting cavity 41 is isolated from the washing cavity 11. It is understood that the mounting cavity 41 is typically used to install various electrical components; while the washing cavity 11 is the space in the dishwasher 1 that directly contacts water and detergent and is used to clean dishes. In other words, the mounting cavity 41 and the washing cavity 11 perform different functions. Therefore, by isolating the mounting cavity 41 from the washing cavity 11, direct contact between electrical components and water can be prevented, thereby reducing the risk of electric shock and short circuits in the dishwasher 1. At the same time, this isolation design prevents water, food residue, detergent, and other substances from splashing into the mounting cavity 41 during the washing process, protecting the electrical components from damage and extending the service life of the dishwasher 1.

[0053] Furthermore, the steam generator is disposed on the outer wall of the mounting cavity 41 or the inner liner 10; that is, the steam generator can be installed in the mounting cavity 41 or on the outer wall of the inner liner 10, and this embodiment does not specifically limit this.

[0054] Please see Figure 2In some embodiments, the ultraviolet sterilization device 30 includes an ultraviolet lamp 31, which is disposed on at least one of the walls of the upper washing chamber 111, the lower washing chamber 112, and the partition plate 14. That is, the ultraviolet lamp 31 can be installed on at least one of the walls of the upper washing chamber 111, the lower washing chamber 112, and the partition plate 14 by welding, screwing, snapping, magnetic attraction, etc., to ensure the connection stability of the ultraviolet lamp 31. Furthermore, this application embodiment does not specifically limit the number of ultraviolet lamps 31; that is, one ultraviolet lamp 31 or multiple ultraviolet lamps 31 can be provided. Moreover, during the operation of the ultraviolet lamp 31, the controller can intelligently adjust the working intensity and irradiation duration of the ultraviolet lamp 31 according to the density and material of the tableware, so as to reduce energy consumption while ensuring sterilization.

[0055] It should be noted that the embodiments of this application do not specifically limit the position of the ultraviolet lamp 31 within the washing cavity 11.

[0056] For example, when the ultraviolet lamp 31 is used to sterilize the upper washing chamber 111, the ultraviolet lamp 31 can be disposed on at least one of the top cavity wall, left cavity wall and right cavity wall of the upper washing chamber 111.

[0057] For example, when the ultraviolet lamp 31 is used to sterilize the lower washing chamber 112, it is disposed on at least one of the top wall, left wall and right wall of the lower washing chamber 112.

[0058] Please continue reading. Figure 2 Furthermore, to ensure the enhanced sterilization capability of the ultraviolet lamp 31 for tableware, in some embodiments, the rear cavity wall of the washing chamber 11 may be provided with a diamond-patterned structure 50. It is understood that the diamond-patterned structure 50 is designed based on the arrangement and combination of several graphics, and through precise carving or printing processes, regular or irregular diamond patterns are formed on the rear cavity wall. When the ultraviolet light emitted by the ultraviolet lamp 31 irradiates the diamond pattern, the light is reflected and refracted at the edges of the diamonds. The reflected light is reflected from the back plate at a specific angle, while the refracted light enters the interior of the rear cavity wall and is reflected and refracted multiple times between the diamonds, ultimately exiting from different positions on the rear cavity wall. This alters the path of the ultraviolet light, allowing it to sterilize the tableware from multiple angles, thereby improving the utilization rate and sterilization efficiency of the ultraviolet light.

[0059] Of course, since the inner liner 10 can be divided into an upper inner liner 12 and a lower inner liner 13, when the ultraviolet lamp 31 is used to sterilize the upper washing chamber 111, the rear wall of the upper washing chamber 111 is provided with a diamond-patterned structure 50 to ensure that the ultraviolet lamp 31 can sterilize the tableware in the upper washing chamber 111 from multiple angles. When the ultraviolet lamp 31 is used to sterilize the lower washing chamber 112, the rear wall of the lower washing chamber 112 is provided with a diamond-patterned structure 50 to ensure that the ultraviolet lamp 31 can sterilize the tableware in the lower washing chamber 112 from multiple angles.

[0060] Please see Figures 1-2 Furthermore, to facilitate the cleaning of filter residue generated during the washing of dishes in the upper washing chamber 111 of the upper inner tank 12, in some embodiments, the dishwasher 1 also includes an upper filter device 60, which is disposed on the partition plate 14. That is, the filter holes opened on the upper filter device 60 are disposed on the partition plate 14, so that the filter residue generated during the washing of dishes in the upper washing chamber 111 can flow into the filter holes, so that the upper filter device 60 can filter the residue and water in the upper washing chamber 111. Of course, a lower filter device is also provided in the lower washing chamber 112 to filter the residue and water in the lower washing chamber 112.

[0061] Since the dishwasher 1 includes a controller, in some embodiments, the dishwasher 1 may further include an identification module electrically connected to the controller and disposed within the washing cavity 11, for identifying tableware within the washing cavity 11. It is understood that the identification module can automatically identify the material of the tableware by integrating image recognition technology. The controller can then control the steam sterilization device 20, or the ultraviolet sterilization device 30, or both simultaneously, based on the identified tableware material. Furthermore, the identification module can also identify the degree of soiling on the tableware to automatically adjust the washing time and sterilization intensity of the dishwasher 1 to achieve optimal cleaning and sterilization results.

In the description of this application, it should be understood that if terms such as "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0063] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
