Description

Technical Field

[0001] This utility model relates to the field of kitchen sink technology, specifically a cleaning device that can be used as a sink and can automatically clean fruits, vegetables, fish, meat and other food ingredients. Background Technology

[0002] For Chinese kitchens, due to the abundance of ingredients, the need for washing fruits, vegetables, fish, and meat is very high. Currently, people mostly use sinks to wash fruits, vegetables, fish, and meat, which is time-consuming and laborious. To solve this problem, the applicant's prior patent ZL201610632336.9, "Integrated Sink Washing Device," discloses a structure that integrates a separate fruit and vegetable washing machine next to the sink. While this provides convenience for users to wash fruits, vegetables, fish, and meat, the drainage components and the drive structure of the fruit and vegetable washing machine are all located at the bottom of the sink, which severely limits the height and volume of the washing machine and the sink, affecting the independent usable space of the sink.

[0003] Paper ZL201821326601.1, "A Sink-Type Washing Machine with Fruit and Vegetable Disposal Unit," discloses a structure that integrates a sink and a sink dishwasher, with a detachable and movable fruit and vegetable disposal unit installed within the sink. While this structure provides convenience for independently washing fruits and vegetables, the spray nozzles of the fruit and vegetable disposal unit actually utilize the same spray arm structure as the sink dishwasher. To avoid clogging this spray arm structure, the fruit and vegetable sink cannot drain water independently, making it inconvenient to use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cleaning device that can automatically drain water when not cleaning, in view of the current state of the prior art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A cleaning device includes a water tank and a detachable food washing tank disposed in the water tank. The food washing tank includes a tank body and a detachable washing basket disposed in the tank body. The bottom of the tank body is provided with a recessed transition area, and a drain outlet is provided at the bottom of the transition area. The bottom of the tank body is provided with a cover plate that can move up and down to open or close the drain outlet.

[0007] The drain outlet of the food washing tank is located directly at the bottom of the tank. When drainage is needed, the drain outlet is opened to directly discharge wastewater into the tank and then drain it away. This achieves automatic drainage without the need for a separate drainage pipe, making it convenient to use. Furthermore, it prevents cross-contamination between pipes, which helps improve reliability and cleaning effect.

[0008] Preferably, the cover plate is located below the outer bottom wall of the tank, and a driving component for moving the cover plate up and down is provided in the transition area. The electric drive of the cover plate to move up and down allows for the opening and closing of the drain outlet, offering high reliability and convenient operation.

[0009] Preferably, the transition area includes an installation chamber located around the drain outlet, and the driving component is a push rod motor housed within the installation chamber. The push rod of the push rod motor passes downward through the bottom wall of the tank and connects to the cover plate. This structure fully utilizes the space of the transition area, improves space utilization, and shortens the driving stroke of the cover plate.

[0010] Preferably, the bottom wall of the cleaning basket is provided with an aeration channel and aeration holes connected to the aeration channel for bubbling into the cleaning basket. The aeration channel is connected to an external air source through an air guide pipe at least partially housed in the transition area. By directly forming the aeration channel and aeration holes on the bottom wall of the cleaning basket, obstruction at the bottom of the cleaning basket is avoided during aeration, and boiling turbulence can be formed in the cleaning basket to improve the cleaning effect.

[0011] Preferably, the air guide tube includes an L-shaped structure housed in the transition region. The vertical portion of the L-shaped structure extends upward and communicates with the aeration channel, while the horizontal portion of the L-shaped structure passes through the side of the transition region and communicates with an external air source. The bottom wall of the cleaning basket has an assembly port communicating with the aeration channel, and the upper end of the vertical portion of the L-shaped structure forms a plug that can be detachably inserted into this assembly port. Using this structure, the air guide tube is installed within the transition region, shortening the air passage and saving assembly space.

[0012] Preferably, the mounting compartment is located on the periphery of the corner of the L-shaped air duct structure to save assembly space.

[0013] Preferably, the transition area constitutes a water inlet area, and a water inlet channel connected to the side of the transition area is provided therewith. A water inlet valve, micro-nano bubble water, or other water inlet structures can be installed outside the water tank. The water inlet channel can be detachably connected to a water supply pipe outside the water tank to achieve automatic and quantitative water supply when the food washing tank is in use.

[0014] Preferably, the transition zone constitutes a sedimentation area for depositing silt and impurities. A filter plate covers the top of the transition zone, and the air duct passes through the filter plate. The filter plate serves as a separator separating the sedimentation area from the washing area above it. This structure relatively separates the aeration and washing area from the silt deposition area to eliminate the impact of turbulent water flow on the silt, prevent the silt from being tumbled by the turbulent water flow due to aeration, thus avoiding secondary pollution and consistently providing stable turbulence.

[0015] Preferably, a fan and air supply duct are provided outside the water tank for supplying air to the food washing tank, and a notch is provided on the side wall of the water tank for detachable connection between the air inlet of the air supply duct and the air outlet of the air supply duct. This structure facilitates detachable connection of the food washing tank to an external active air source.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets the drain outlet of the food washing tank directly at the bottom of the tank. When drainage is needed, the drain outlet is opened to directly discharge the wastewater into the tank and then drain it away. There is no need to set up an independent drainage pipe, and automatic drainage can be achieved. It is convenient to use, and there is no cross-contamination between the pipes, which helps to improve reliability and cleaning effect. Attached Figure Description

[0024] The drain outlet 212 of the food washing tank 2 is directly set at the bottom of the tank body 21. When drainage is needed, the drain outlet 212 is opened to directly discharge the wastewater into the water tank 1 and then drain it away. There is no need to set up a separate drainage pipe, which can achieve automatic drainage. It is convenient to use, and there is no cross-contamination between the pipes, which helps to improve reliability and cleaning effect.

[0025] The cover plate 4 is located below the outer bottom wall of the tank 21, and a drive unit 5 for driving the cover plate 4 to move up and down is provided in the transition area 211. The cover plate 4 is electrically driven to move up and down, and the drain outlet 212 is opened and closed by the cover plate 4. It has good reliability and is easy to operate.

[0026] A mounting chamber is provided in the transition area 211, located around the drain outlet 212. The driving component 5 is a push rod 51 motor located in the mounting chamber. The push rod 51 of the push rod 51 motor passes downward through the bottom wall of the tank 21 and connects to the cover plate 4. This structure is adopted to make full use of the space in the transition area 211, improve space utilization, and shorten the driving stroke of the cover plate 4.

[0027] The bottom wall of the cleaning basket 22 is provided with an aeration channel 221 and aeration holes 222 connected to the aeration channel 221 for bubbling into the cleaning basket 22. The aeration channel 221 is connected to an external air source through an air guide pipe 3 at least partially housed in the transition region 211. By directly forming the aeration channel 221 and aeration holes 222 on the bottom wall of the cleaning basket 22, obstruction at the bottom of the cleaning basket 22 is avoided during aeration, and boiling turbulence can be formed in the cleaning basket 22 to improve the cleaning effect.

[0028] The air duct 3 includes an L-shaped structure housed in the transition region 211. The vertical portion of this L-shaped structure extends upwards and communicates with the aeration channel 221, while the horizontal portion passes through the side of the transition region 211 and communicates with an external air source. The bottom wall of the cleaning basket 22 has an assembly port 223 that communicates with the aeration channel 221. The upper end of the vertical portion of the L-shaped structure forms a plug 32 that can be detachably inserted into this assembly port. Using this structure, the air duct 3 is installed within the transition region 211, shortening the air passage and saving assembly space.

[0029] The installation compartment is located on the outer perimeter of the L-shaped corner of the air duct 3 to save assembly space.

[0030] The transition area 211 constitutes the water inlet area, and a water inlet channel 214 connected to the side of the transition area 211 is provided thereto. A water inlet valve, micro-nano bubble water or other water inlet structures can be installed outside the water tank 1. The water inlet channel 214 can be detachably connected to the water supply pipe outside the water tank 1 to achieve automatic and quantitative water supply when the food washing tank 2 is in use.

[0031] The transition zone 211 forms a sedimentation zone for depositing silt and impurities. A filter plate 6 covers the top of the transition zone 211, and an air guide pipe 3 passes through the filter plate 6. The filter plate 6 serves as a separator to separate the sedimentation zone from the washing zone above it. This structure relatively separates the aeration and washing zone from the silt deposition zone to eliminate the impact of turbulent water flow on the silt, prevent the silt from being tumbled by the turbulent water flow due to aeration, thus avoiding secondary pollution and consistently providing stable turbulence.

[0032] A fan and air supply duct are installed outside the water tank 1 to supply air to the food washing tank 2. The air supply duct and water supply duct are integrated into a single flat module 200. The side wall of the water tank 1 has a notch 100 for detachable connection between the air inlet of the air supply pipe 3 and the air outlet of the air supply duct. This structure facilitates detachable connection of the food washing tank 2 to an external active air source.

[0033] Existing methods of combining food washing tanks with sinks or sink dishwashers result in the food washing tank occupying the sink's usable space. This utility model provides a food washing tank that can be combined with or separated from the sink. When combined with the sink, it is an electric washing tank; when separated from the sink, it reverts to an independent large sink, thus meeting the different cleaning needs of users.

[0034] This invention places the drain outlet of the food washing tank directly at the bottom of the tank. When drainage is needed, the drain outlet is opened to directly discharge wastewater into the tank and then drain it away. It can achieve automatic drainage without the need for a separate drainage pipe, making it convenient to use. Furthermore, it prevents cross-contamination between pipes, which helps improve reliability and cleaning effect.
