Abstract
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] Furthermore, for fruit and vegetable washing, creating turbulence by bubbling water is a good washing method. However, for fruit and vegetable troughs, the required water level is relatively high, which can easily lead to overflow. Overflow may damage electrical components and affect the normal use of the washing device. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a cleaning device that does not affect the independent usable volume of the water tank, provides automatic cleaning function, and avoids damage to electrical components caused by high water level overflow, in light of the current state of the technology.
[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 food washing tank detachably disposed in the water tank, and also includes a fan and an air inlet pipe. The side wall of the food washing tank is provided with an air inlet interface. The air inlet pipe is disposed on the outer side wall of the water tank and has a first port for connecting with the air inlet interface. The side wall of the water tank has an assembly port for connecting the air inlet interface with the first port. The fan is disposed on the outer side wall of the water tank and arranged near its upper edge. The air inlet pipe has a second port connected to the air outlet of the fan.
[0007] Existing methods of combining food washing tanks with sinks or sink dishwashers result in the food washing tank occupying space within the sink. This invention provides a food washing tank that can be combined with or separated from the sink. When combined with the sink, it functions as an electric washing tank; when separated, it reverts to a large, independent sink, thus meeting different user cleaning needs. The fan is positioned near the top edge of the sink to ensure the water level in the food washing tank remains below the fan, preventing overflow from the inlet pipe and potential damage to the fan due to excessively high water levels.
[0008] In this invention, the fan is positioned above the water level in the food washing tank. This design prevents the inlet pipe from overflowing and damaging the fan.
[0009] Preferably, the air inlet pipe is located on the left or right side wall of the sink and is in a horizontal L-shape. The first arm of the L-shape extends vertically and its lower end forms a first port corresponding to the mounting opening. The second arm of the L-shape extends laterally to the junction of the left / right side wall and the rear side wall of the sink. The fan is located on the rear side wall of the sink, and its air outlet is connected to the end of the second arm of the L-shape. This structure effectively elevates the horizontal portion of the air inlet pipe, keeping it above the washing water level in the food washing tank over a greater range of motion, thus mitigating the risk of water overflow from the inlet pipe.
[0010] Preferably, the fan is vertically arranged on the rear side wall of the water tank with its air inlet facing forward, and the air outlet is located at the top of the fan and extends laterally to correspond to the second arm of the L-shaped structure. This structure, by placing the fan's air outlet at the top, provides space for a higher installation of the air inlet duct.
[0011] Preferably, the height of the second arm of the L-shaped structure is above the washing water level in the food washing tank. This structure helps to further reduce the risk of overflow from the air inlet pipe.
[0012] This invention also includes a drainage component for draining water from the food washing tank. The maximum drainage height of the drainage component is lower than the maximum air intake height of the fan and / or air intake pipe. The drainage component allows water to be directly drained from the food washing tank, facilitating cleaning. Furthermore, when the water level in the food washing tank becomes too high due to various factors, because the maximum drainage height of the drainage component is lower than the maximum air intake height of the fan and / or air intake pipe, excess water can first be drained through the drainage component, preventing backflow to the fan through the air intake pipe and further providing overflow protection for the fan.
[0013] Preferably, the drainage assembly includes a water outlet pipe, a drainage pump, and a drain pipe. The side wall of the food washing tank has a drain port no higher than the air inlet. The water outlet pipe is horizontally positioned on the left or right side wall of the tank and below the air inlet pipe. The first end of the water outlet pipe is connected to the drain port. The drainage pump is located on the rear side wall of the tank. The water outlet pipe extends to the rear side wall of the tank, and its second end is connected to the inlet on the side of the drainage pump. The outlet of the drainage pump is located at its top and connected to the drain pipe. This structure not only provides a more reasonable installation method for the air intake and drainage structure, improving space utilization, but also allows overflow water from the food washing tank to be preferentially discharged through the drainage assembly, protecting the fan.
[0014] Preferably, the drain pipe is partially elevated to form an inverted U-shaped elevation structure, the highest point of which is lower than the maximum air intake height of the fan and / or air inlet pipe. This elevation structure prevents water overflow from the food washing tank without valves in the pipe, and by ensuring the highest point is below the maximum height of the fan and / or air inlet pipe, any overflow can be drained away through the drainage assembly, thus protecting the fan.
[0015] Preferably, the drain interface also serves as the water inlet of the food washing tank. A water inlet pipe, located above the outlet pipe, is provided on the left or right side wall of the tank. This water inlet pipe extends to the rear side wall of the tank and connects to a water inlet assembly located on the rear side wall. This structure facilitates the introduction of water into the food washing tank through a simple design.
[0016] Preferably, the water inlet assembly is equipped with a water inlet valve for controlling whether water enters the tank and a flow sensor that works with the water inlet valve to control the water volume. The water inlet assembly may also include a micro-nano bubble generator to supply micro-nano bubble water to the food washing tank, further improving the washing effect. The aforementioned water inlet valve and flow sensor work together to control the water volume in the food washing tank, ensuring the water level is below the height of the fan and preventing overflow that could damage the fan.
[0017] Compared with the prior art, the advantages of this utility model are as follows: This utility model detachably installs the food washing tank in the water tank. When the food washing tank is needed, it is placed in the water tank, and the washing tank is bubbled and cleaned by a fan and an air inlet pipe. When the food washing tank is not needed, it can be removed from the water tank, so that the water tank has a large volume of cleaning space to meet the user's needs. The fan is arranged close to the top edge of the water tank so that the water level in the food washing tank is always lower than the fan, so as to avoid the water level being too high and the water inlet pipe overflowing and damaging the fan.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1-5 As shown, the cleaning device of this embodiment includes a water tank 1 and a food washing tank 2 detachably disposed in the water tank 1, and also includes a fan 31 and an air inlet pipe 32. The side wall of the food washing tank 2 is provided with an air inlet interface 21. The air inlet pipe 32 is disposed on the outer side wall of the water tank 1 and has a first port 321 for communicating with the air inlet interface 21. The side wall of the water tank 1 is provided with an assembly port 10 for communicating with the air inlet interface 21 and the first port 321. The fan 31 is disposed on the outer side wall of the water tank 1 and arranged near its upper edge. The air inlet pipe 32 has a second port 322 connected to the air outlet 311 of the fan 31.
[0025] In existing methods of combining the food washing tank 2 with the sink 1 or the dishwasher, the food washing tank 2 occupies the usable space of the sink 1. This embodiment provides a food washing tank 2 that can be combined with or separated from the sink 1. When combined with the sink 1, it is an electric washing tank; when separated from the sink 1, it reverts to an independent large sink 1, thus meeting different user cleaning needs. The fan 31 is positioned close to the top edge of the sink 1 to ensure that the water level in the food washing tank 2 is always lower than the fan 31, preventing the water level from being too high and causing overflow from the inlet pipe, which could damage the fan 31.
[0026] In this embodiment, the fan 31 is positioned above the washing water level in the food washing tank 2. This design is to prevent overflow from the water inlet pipe from damaging the inverted fan 31.
[0027] The air inlet pipe 32 is located on the left or right side wall of the water tank 1 (in this embodiment, it is located on the right side wall) and is in a horizontal L-shaped structure. The first arm of the L-shaped structure extends vertically and its lower end forms a first port 321 corresponding to the mounting opening. The second arm of the L-shaped structure extends laterally to the junction of the left / right side wall and the rear side wall of the water tank 1. The fan 31 is located on the rear side wall of the water tank 1 and its air outlet 311 is connected to the end of the second arm of the L-shaped structure. By adopting the above structure, the horizontal part of the air inlet pipe 32 is designed to be suspended high, so that it remains above the washing water level in the food washing tank 2 for a large range of strokes, thereby reducing the risk of water overflow from the water inlet pipe.
[0028] The fan 31 is vertically arranged on the rear side wall of the water tank 1 with the air inlet 312 facing forward. The air outlet 311 is located at the top of the fan 31 and extends laterally to correspond to the second arm of the L-shaped structure. With the above structure, the air outlet 311 of the fan 31 is located at the top, thereby providing conditions for installing the air inlet duct 32 at a higher position.
[0029] The second arm of the L-shaped structure is positioned above the washing water level in the food washing tank 2. This structure helps to further reduce the risk of overflow from the air inlet duct 32.
[0030] This embodiment also includes a drainage component 4 for draining water from the food washing tank 2. The maximum drainage height of the drainage component 4 is lower than the maximum air intake height of the fan 31 and / or the air intake pipe 32. The drainage component 4 allows water to be directly drained from the food washing tank 2, facilitating cleaning. Furthermore, when the water level in the food washing tank 2 becomes too high due to various factors, since the maximum drainage height of the drainage component 4 is lower than the maximum air intake height of the fan 31 and / or the air intake pipe 32, excess water can first be drained through the drainage component 4, preventing backflow to the fan 31 through the air intake pipe 32, thus further providing overflow protection for the fan 31.
[0031] The drainage assembly 4 includes a water outlet pipe 41, a drainage pump 42, and a drain pipe 43. A drain port 22, not higher than the air inlet port 21, is provided on the side wall of the food washing tank 2. The water outlet pipe 41 is horizontally positioned on the left or right side wall of the tank 1 and located below the air inlet pipe 32. The first end of the water outlet pipe 41 is connected to the drain port 22. The drainage pump 42 is located on the rear side wall of the tank 1. The water outlet pipe 41 extends to the rear side wall of the tank 1, and its second end is connected to the inlet 421 on the side of the drainage pump 42. The outlet 422 of the drainage pump 42 is located at its top and connected to the drain pipe 43. This structure not only provides a more reasonable installation method for the air intake and drainage structure, improving space utilization, but also allows overflow water in the food washing tank 2 to be preferentially discharged through the drainage assembly 4, protecting the fan 31.
[0032] The partial elevation of the drain pipe 43 forms an inverted U-shaped elevation structure 431. The highest point of this U-shaped elevation structure 431 is lower than the maximum air intake height of the fan 31 and / or the air inlet pipe 32. This elevation structure of the drain pipe 43 prevents water overflow from the food washing tank 2 without the need for valves in the pipe. Furthermore, by ensuring its highest point is lower than the maximum height of the fan 31 and / or the air inlet pipe 32, any overflow can be drained away through the drain assembly 4, thus protecting the fan 31.
[0033] The drain port 22 also serves as the water inlet for the food washing tank 2. A water inlet pipe 51, located above the water outlet pipe 41, is provided on the left or right side wall of the tank 1. This water inlet pipe 51 extends to the rear side wall of the tank 1 and connects to the water inlet assembly 5 located on the rear side wall of the tank 1. This structure facilitates the introduction of water into the food washing tank 2 through a simple design.
[0034] The water inlet assembly 5 is equipped with a water inlet valve 52 to control whether water enters the tank, and a flow sensor that works with the water inlet valve 52 to control the amount of water entering the tank. The water inlet assembly 5 may also include a micro-nano bubble generator 53 to supply micro-nano bubble water to the food washing tank 2, further improving the washing effect. The aforementioned water inlet valve 52, in conjunction with the flow sensor, controls the amount of water entering the food washing tank 2, ensuring the water level is below the height of the fan 31 to prevent overflow and damage to the fan 31.
[0035] In this embodiment, the water inlet, air inlet, and drainage structures are all integrated together and installed on the left / right side wall and rear side wall of the water tank 1. They are arranged in a flat structure to greatly save installation space and improve space utilization.
[0036] In this embodiment, the food washing tank 2 is detachably installed in the water tank 1. When the food washing tank 2 is needed, it is placed in the water tank 1, and the food washing tank 2 is bubbled cleaned by the fan 31 and the air inlet pipe 32. When the food washing tank 2 is not needed, it can be removed from the water tank 1, so that the water tank 1 has a large volume of cleaning space to meet the user's needs. The fan 31 is arranged close to the top edge of the water tank 1 so that the water level in the food washing tank 2 is always lower than the fan 31, so as to avoid the water level being too high and the water inlet pipe overflowing and damaging the fan 31.
