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 drain outlet and a drain trough that can be moved up and down below the drain outlet. The drain trough moves upward to close the drain outlet and moves downward to open the drain outlet.

[0007] 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 away. It 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. A drainage trough is set below the drain outlet for opening and closing it. The drainage trough itself can serve as a buffer area for the tank to improve the turbulence stability in the food washing tank, thereby improving the cleaning effect.

[0008] Preferably, a sealing strip is provided at the top edge of the drainage channel, and when the drain outlet is closed, the sealing strip elastically seals between the bottom wall of the outer wall of the channel and the top edge of the drainage channel. This structure improves the sealing performance when the drain outlet is closed, preventing water leakage.

[0009] Preferably, the food washing tank is equipped with a drive component for driving the drainage tank to move up and down. The lower part of the drive component is connected to the drainage tank, and the upper part of the drive component protrudes above the food washing tank. This structure enables automatic drainage.

[0010] Preferably, the driving component is a linkage assembly arranged close to the inner wall of the tank, and the linkage assembly is provided with an elastic element that enables it to maintain a contraction trend, thereby moving the drainage tank upwards to close the drain outlet. The vertical movement of the drainage tank is achieved through a simple linkage assembly, resulting in a simple structure and high reliability.

[0011] Preferably, the linkage assembly includes a first link, a second link, a third link, and a fourth link connected end-to-end to form a closed structure. The upper ends of the first link and the second link are rotatably connected, and the lower ends of the first link and the third link are rotatably connected. The lower ends of the second link and the fourth link are rotatably connected, and the lower ends of the third link and the fourth link are rotatably connected. The elastic element is disposed within the closed structure formed by the first link, the second link, the third link, and the fourth link, with the upper end of the elastic element abutting against the upper ends of the first link and the second link, and the lower end of the elastic element abutting against the lower ends of the third link and the fourth link, thereby forming an up-and-down telescopic structure. This four-link structure improves the reliability of the up-and-down contraction structure, thereby achieving stable up-and-down drive of the drainage channel.

[0012] Preferably, the connection between the first and third connecting rods is connected to the inner bottom wall of the drainage trough via a downwardly extending first connecting arm, and the connection between the second and fourth connecting rods is connected to the inner bottom wall of the drainage trough via a downwardly extending second connecting arm. This structure facilitates a reliable connection between the drive assembly and the drainage trough.

[0013] Preferably, the connection between the first and second connecting rods is provided with a pressing member that extends upward and protrudes above the food washing tank. With this structure, when drainage is needed, the pressing member can be pressed down. When the force applied to the pressing member is released, the connecting rod assembly can automatically return to its original position under the action of the elastic member, thereby driving the drainage tank to close the drain outlet.

[0014] 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 drainage trough. 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.

[0015] Preferably, the air guide pipe includes an L-shaped structure housed in a drainage trough. 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 drainage trough 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 pipe is installed using the drainage trough, shortening the air passage and saving assembly space.

[0016] Preferably, the drainage trough forms a water inlet area, and a water inlet channel connected to it is provided on the side of the drainage trough. A water inlet valve, micro-nano bubble water, or other water inlet structures can be installed outside the water tank, and the water inlet channel can be detachably connected to the water supply pipe outside the water tank to achieve automatic and quantitative water supply when the food washing tank is in use.

[0017] Preferably, the drainage trough has a bowl-shaped structure, forming a sedimentation area for depositing silt and impurities. A filter plate covers the top of the drainage trough, and the air guide pipe passes through the filter plate. The filter plate acts 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, eliminating the impact of turbulent water flow on the silt and preventing the silt from being tumbled by the turbulent water flow due to aeration, thus avoiding secondary pollution and consistently providing stable turbulence.

[0018] 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.

[0019] 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

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-5 As shown, the cleaning device in this embodiment includes a water tank 1 and a food washing tank 2 detachably installed in the water tank 1. A wastewater outlet 13 is provided at the bottom of the water tank 1. The food washing tank 2 includes a tank body 21 and a washing basket 22 detachably installed in the tank body 21. A drain outlet 212 and a drain trough 4 that can move up and down below the drain outlet 212 are provided at the bottom of the tank body 21. The drain trough 4 moves upward to close the drain outlet 212 and moves downward to open the drain outlet 212.

[0027] In this embodiment, the drain outlet 212 of the food washing tank 2 is directly set at the bottom of the tank body 21. When drainage is required, the drain outlet 212 is opened to directly discharge wastewater into the water tank 1 and then drain it away. Automatic drainage can be achieved without setting up a separate drainage pipe, which is convenient to use and prevents cross-contamination between the pipes, which is beneficial to improving reliability and cleaning effect. A drainage trough 4 is set below the drain outlet 212 for opening and closing. The drainage trough 4 itself can serve as a buffer area for the tank body 21 to improve the turbulence stability in the food washing tank 2, thereby improving the cleaning effect.

[0028] A sealing strip 41 is provided at the top edge of the drainage trough 4. When the drain outlet 212 is closed, the sealing strip 41 elastically seals between the bottom wall of the trough 21 and the top edge of the drainage trough 4. This structure can improve the sealing performance when the drain outlet 212 is closed and prevent water leakage.

[0029] The food washing tank 2 is equipped with a drive assembly 5 for driving the drainage tank 4 to move up and down. The lower part of the drive assembly 5 is connected to the drainage tank 4, and the upper part of the drive assembly 5 protrudes above the food washing tank 2. This structure enables automatic drainage.

[0030] The drive assembly 5 is a linkage assembly arranged close to the inner wall of the tank 21, and this linkage assembly is provided with an elastic element 50 that enables it to maintain a contraction trend, thereby moving the drainage tank 4 upward and closing the drain outlet 212. The vertical movement of the drainage tank 4 is achieved through a simple linkage assembly, which has a simple structure and good reliability.

[0031] The linkage assembly includes a first link 51, a second link 52, a third link 53, and a fourth link 54 connected end-to-end to form a closed structure. The upper end of the first link 51 is rotatably connected to the upper end of the second link 52, the lower end of the first link 51 is rotatably connected to the upper end of the third link 53, the lower end of the second link 52 is rotatably connected to the upper end of the fourth link 54, and the lower end of the third link 53 is rotatably connected to the lower end of the fourth link 54. An elastic element 50 is disposed within the closed structure formed by the first link 51, the second link 52, the third link 53, and the fourth link 54, with the upper end of the elastic element 50 abutting against the upper ends of the first link 51 and the second link 52, and the lower end of the elastic element 50 abutting against the lower ends of the third link 53 and the fourth link 54, thereby forming an up-and-down telescopic structure. This four-link structure improves the reliability of the up-and-down contraction structure, thereby achieving stable up-and-down drive of the drainage trough 4.

[0032] The connection between the first link 51 and the third link 53 is connected to the inner bottom wall of the drainage trough 4 via a downwardly extending first connecting arm 55, and the connection between the second link 52 and the fourth link 54 is connected to the inner bottom wall of the drainage trough 4 via a downwardly extending second connecting arm 56. This structure facilitates a reliable connection between the drive assembly 5 and the drainage trough 4.

[0033] A pressing element 57 extending upwards and protruding above the food washing tank 2 is provided at the connection point of the first connecting rod 51 and the second connecting rod 52. With this structure, when drainage is needed, the pressing element 57 can be pressed down. When the force applied to the pressing element 57 is released, the connecting rod assembly can automatically return to its original position under the action of the elastic element 50, thereby driving the drainage tank 4 to close the drain outlet 212.

[0034] 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 that is at least partially housed in the drain trough 4. 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.

[0035] The air guide pipe 3 includes an L-shaped structure housed in the drain trough 4. The vertical portion of the L-shaped structure extends upward and communicates with the aeration channel 221, while the horizontal portion of the L-shaped structure passes through the side of the drain trough 4 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 guide pipe 3 is installed using the drain trough 4, shortening the air passage and saving assembly space.

[0036] The drainage trough 4 forms the water inlet area, and a water inlet channel 214 is provided on the side of the drainage trough 4 to connect with it. 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.

[0037] The drainage trough 4 forms a sedimentation area for depositing silt and impurities. A filter plate 6 covers the top of the drainage trough 4, and an air guide pipe 3 passes through the filter plate 6. The filter plate 6 serves as a separator to separate 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.

[0038] 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.

[0039] 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.
