[0026] Reference Figure 1-4 An ultraviolet disinfecting sink dishwasher according to an embodiment of the utility model is described.

[0027] In one embodiment, a dishwasher with an ultraviolet disinfection water tank 1 includes a dishwasher body, which includes a water tank 1 and a cleaning tank 2; a cleaning tank cover 3 is provided on the cleaning tank 2, and the cleaning tank cover 3 includes an operating panel 31 and a bottom plate 32, and a push-pull mechanism 33 and an ultraviolet disinfection component 34 are provided in the interlayer between the operating panel 31 and the bottom plate 32, and the operating panel 31 is connected to the push-pull mechanism 33 and the ultraviolet disinfection component 34 respectively; one end of the push-pull mechanism 33 is fixedly connected to the side wall of the interlayer, and the other end is fixedly connected to the ultraviolet disinfection component 34, and the push-pull mechanism 33 is used to drive the ultraviolet disinfection component 34 to move between a first position and a second position, the first position is located inside the interlayer, and the second position is located outside the cleaning tank cover 3.

[0028] Among them, the bottom plate 32 covers the upper surface of the cleaning tank 2, and the bottom plate 32 is a transparent quartz glass plate. Transparent quartz glass has excellent light transmission performance, and the maximum transmittance in the ultraviolet spectrum region can reach more than 80%. The ultraviolet rays emitted by the ultraviolet disinfection component 34 can pass through the bottom plate 32 to fully disinfect the tableware in the cleaning tank 2. At the same time, quartz glass also has the advantages of high temperature resistance, corrosion resistance, and good thermal stability, and is suitable for dishwashers that need to operate in a high temperature environment. When the bottom plate 32 is covered on the cleaning tank 2, its four sides are tightly fitted with the edge of the upper end face of the cleaning tank 2 to ensure the airtightness of the cleaning tank 2 during steam cleaning and disinfection, and prevent the high-temperature steam from escaping and causing danger. Specifically, a sealing strip can be set between the edge of the bottom plate 32 and the upper end face of the cleaning tank 2 to improve the sealing.

[0029] In specific implementation, before the cleaning tank 2 is about to start high-temperature cleaning, the push-pull mechanism 33 drives the ultraviolet disinfection component 34 to move from the internal interlayer position of the cleaning tank cover 3 to the outside of the cleaning tank cover 3. After the high-temperature cleaning is completed, after a period of time or when the temperature of the cleaning tank 2 drops to room temperature, the push-pull mechanism 33 drives the ultraviolet disinfection component 34 back to the internal interlayer of the cleaning tank cover 3, and the tableware in the cleaning tank 2 is disinfected by ultraviolet light according to user needs.

[0030] The ultraviolet disinfection water tank 1 dishwasher in this embodiment is provided with a push-pull mechanism 33 and an ultraviolet disinfection component 34 inside the cleaning tank cover 3, and the ultraviolet disinfection component 34 can be pushed out of the cleaning tank cover 3 through the push-pull mechanism 33 to prevent the ultraviolet disinfection component 34 from contacting the high-temperature environment during cleaning, thereby achieving the purpose of reducing the impact of high temperature on the ultraviolet lamp tube, thereby effectively extending the service life of the ultraviolet lamp tube.

[0031] In this embodiment, the operation panel 31 is connected to a temperature sensor, and the temperature sensor is attached to the upper surface of the bottom plate 32. The operation panel 31 is connected to the temperature sensor, and the temperature sensor is used to detect the upper surface temperature of the bottom plate 32. As an implementation method of this embodiment, after the high-temperature cleaning in the cleaning tank 2 is completed, the ultraviolet disinfection component 34 does not immediately return to the inner interlayer of the cleaning tank cover 3, until the upper surface temperature of the bottom plate 32 detected by the temperature sensor has dropped to a safe temperature, the operation panel 31 will control the push-pull mechanism 33 to drive the ultraviolet disinfection component 34 back to the inner interlayer of the cleaning tank cover 3, thereby ensuring that the ultraviolet disinfection component 34 is always in a safe temperature environment, which helps to extend the service life of the ultraviolet lamp.

[0032] In this embodiment, the first position is located above the middle of the bottom plate 32. The ultraviolet disinfection assembly 34 is located above the middle of the bottom plate 32, facing the tableware in the cleaning tank 2, so as to facilitate disinfection of the tableware in the cleaning tank 2.

[0033] In this embodiment, the second position is located above the water tank 1. Specifically, when the ultraviolet disinfection component 34 is located above the water tank 1, the ultraviolet disinfection component 34 can also be controlled to start through the operation panel 31 to disinfect the water tank 1 of the dishwasher.

[0034] In this embodiment, the push-pull mechanism 33 is an electric push-pull mechanism with a simple structure and low cost; the ultraviolet disinfection component 34 includes at least two ultraviolet lamp tubes to achieve more complete disinfection and sterilization.

[0035] In another embodiment, the dishwasher body further includes a steam assembly 4, which includes a steam generator 41, a water tank 42 and a steam nozzle 43 disposed in the cleaning tank 2, and the steam generator 41 is respectively connected to the water tank 42 and the steam nozzle 43. In specific implementation, the above-mentioned ultraviolet disinfection water tank 1 dishwasher not only has the ultraviolet disinfection function, but also can spray high-temperature steam into the cleaning tank 2 through the steam generator 41 to achieve the functions of high-temperature cleaning and disinfection, making the water tank 1 dishwasher more comprehensive.

[0036] In this embodiment, the steam assembly 4 further includes a water pump 44, and the water tank 42 is connected to the steam generator 41 via the water pump 44. The water pump 44 is used to pump the water in the water tank 42 to the steam generator 41.

[0037] In this embodiment, the dishwasher body further includes an anti-overflow protection box 5 and a water inlet valve 6. The drain port of the sink 1 is connected to a drain pipe. The first water outlet of the water inlet valve 6 is connected to the water tank 42, and the second water outlet of the water inlet valve 6 is connected to the water inlet of the anti-overflow protection box 5. Water is injected into the cleaning tank 2 through the anti-overflow protection box 5. The overflow port of the anti-overflow protection box 5 is connected to the drain pipe. The drain pipe can be connected to the household sewer, and the water inlet of the water inlet valve 6 is connected to the water supply pipeline. When the sink 1 dishwasher is installed, a drain pipe will also be provided at the bottom of the cleaning tank 2, and the drain pipe is also connected to the drain pipe.
