Description

Technical Field

[0001] This utility model relates to the field of kitchen cleaning sink technology, specifically to a food cleaning sink and cleaning device that can clean fruits, vegetables, fish and meat. 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 Dispenser," discloses a structure that integrates a sink and a sink dishwasher, with a detachable and movable fruit and vegetable dispenser installed within the sink. While this structure provides convenience for independent washing of fruits and vegetables, the spray nozzles of this fruit and vegetable cleaner actually use the same spray arm structure as the sink dishwasher, and the water supply for the spray nozzles requires the original sink dishwasher's water supply system. For the aforementioned fruit and vegetable cleaner, it mainly utilizes the return water jets from the spray arms to provide turbulent water flow for washing fruits and vegetables. This results in relatively low turbulence, mainly concentrated in the central part of the bottom of the fruit and vegetable trough, while the turbulence at the edges is very weak, leading to poor cleaning results. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a food washing tank that can effectively improve the cleaning effect, in light of the current state of the technology.

[0005] The second technical problem to be solved by this utility model is to provide a cleaning device that uses the above-mentioned food washing tank, in view of the current situation of the prior art.

[0006] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows:

[0007] A food washing tank includes an outer tank and a draining tank detachably disposed in the outer tank. The bottom of the draining tank is provided with an aeration channel that can be connected to an external air source. The inner bottom wall of the draining tank is provided with aeration holes and jet holes that are connected to the aeration channel. The diameter of the jet holes is smaller than that of the aeration holes. The aeration holes are used to create a turbulent flow pattern in the water, and the jet holes are used to create an impact-type washing zone.

[0008] During washing, the draining tank aerates air through its bottom aeration channels, aeration holes, and jet holes. The aeration holes blow air upwards from the bottom of the tank, maintaining a large-scale turbulent flow. The jet holes, in conjunction with the turbulent flow, spray a more concentrated upward impact jet, resulting in a more powerful rinse of the food, effectively removing pesticide residues and dirt from the surface and improving cleaning efficiency. Furthermore, the aeration holes on the bottom wall of the draining tank directly aerate the water, without obstruction, creating a boiling-like turbulent flow that further enhances the cleaning effect.

[0009] Preferably, the aeration holes are multiple and arranged circumferentially around the bottom wall of the draining tank, and the jet holes are arranged within the circle surrounding the aeration holes. This structure expands the turbulence range, prevents food from moving around in the draining basket, and improves the cleaning effect.

[0010] Preferably, the aeration channel includes an orifice-shaped main body arranged around the edge of the bottom wall of the drain tank. Several aeration holes are arranged at intervals on the orifice-shaped main body. A jet channel connects the two opposite long sides of the orifice-shaped main body, and several jet holes are arranged at intervals corresponding to the jet channels. This structure creates a more regular and wider-coverage turbulent cleaning area, further improving the cleaning effect.

[0011] Preferably, the width of the jet channel is smaller than the width of any side of the orifice body. The jet channel needs to supply the jet orifice with a finer impact gas column; setting its width narrower helps to increase the impact height of the jet gas.

[0012] Preferably, a through channel is connected at the midpoint of the two opposite long sides of the mouth-shaped main body. Two dividing ribs, extending along the length of the through channel and arranged side-by-side, form a jet channel within the two dividing ribs and an air passage connecting the mouth-shaped main body outside the two dividing ribs. A jet channel is also provided on each side of the through channel. This structure allows jet airflow to be formed at the center and sides of the bottom of the drain tank, improving the coverage of the jet airflow and enhancing the cleaning effect.

[0013] Preferably, an air inlet for the aeration channel is provided at the central part of the bottom of the through channel, and two sets of jet channels are distributed on both sides of the air inlet. The air passage is used to connect the incoming air from the air inlet with the main body of the inlet. This structure facilitates the supply of air to the aeration channel and makes it convenient to distribute the gas.

[0014] Preferably, an air guide pipe with its air outlet facing upward is provided below the draining trough. The outer bottom wall of the draining trough has an assembly port for the upper end of the air guide pipe to be detachably inserted and connected to the aeration channel; this assembly port is the aforementioned air inlet. The bottom of the outer trough has a partially recessed water-passing area, and at least a portion of the air guide pipe is housed within this water-passing area. The aeration channel at the bottom of the draining trough is detachably connected to the air guide pipe at the bottom of the outer trough, facilitating the selection of whether or not the air passage is connected as needed. The air guide pipe being at least partially located in the water-passing area improves the compactness of the air intake and drainage structures, making full use of the space in the food washing tank.

[0015] Preferably, the top of the water-passing area is covered with a filter plate, and the air guide pipe passes through the filter plate with its upper end protruding above it. The filter plate filters out large impurities, preventing them from entering the water-passing area and causing blockages in the inlet and outlet. Simultaneously, the filter plate allows silt and small impurities to enter, preventing them from entering the drain tank and being turbulently swept away, thus improving the cleaning effect. The air guide pipe has an L-shaped structure with a horizontal and a vertical portion. The horizontal portion is located in the water-passing area, with its inlet extending to the side of the water-passing area, while the vertical portion passes through the filter plate. This structure facilitates the proper installation of the air guide pipe, fully utilizes installation space, shortens the air delivery stroke, and improves the aeration effect.

[0016] A cleaning device includes a water tank and a food washing tank, which is detachably mounted within the water tank. The water tank is longer in the lateral direction than in the front-to-back direction to provide a large washing space in the lateral direction, accommodating the washing of long tableware. This structure can shorten the height of the water tank, providing space utilization beneath it. The food washing tank can be laterally mounted in the water tank via supports at the top and / or bottom. Water inlet / drainage and air inlet structures are correspondingly provided on the sidewalls of the water tank and the sidewalls of the food washing tank. The food washing tank can be connected to or separated from the medium inlet on the sidewall of the water tank by moving the food washing tank left and right. In existing methods of combining food washing tanks with water tanks or water tank dishwashers, the food washing tank occupies the usable space of the water tank. This invention provides a food washing tank that can be combined with or separated from the water tank. When combined with the water tank, it is an electric cleaning tank; when separated, it reverts to an independent large water tank, meeting different user cleaning needs.

[0017] Preferably, an air pump assembly for supplying air to the aeration channel is installed outside the water tank, and this air pump assembly is detachably connected to the food washing tank. This structure facilitates the provision of boiling-type turbulence through the aeration channel to improve the washing effect.

[0018] Compared with the prior art, the advantages of this utility model are as follows: the draining tank of this utility model holds food. During washing, the draining tank blows air into the draining tank through the aeration channel, aeration holes and jet holes at its bottom. The aeration holes blow air from the bottom of the draining tank upwards, maintaining a large-scale turbulent flow pattern of the water. The jet holes, in conjunction with the turbulent flow, spray a more concentrated upward impact jet, thereby washing the food more powerfully, so as to forcefully remove pesticide residues and dirt from the surface of the food to be washed, and improve the washing effect.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1-8 As shown, the food washing tank 100 of this embodiment includes an outer tank 1 and a draining tank 2 detachably disposed in the outer tank 1. The bottom wall of the draining tank 2 is provided with a plurality of draining holes 21. The bottom of the draining tank 2 is provided with an aeration channel 3 that can be connected to an external air source. The inner bottom wall of the draining tank 2 is provided with aeration holes 31 and jet holes 30 that are connected to the aeration channel 3. The diameter of the jet holes 30 is smaller than the diameter of the aeration holes 31. The aeration holes 31 are used to form a turbulent water flow pattern, and the jet holes 30 are used to form an impact-type washing area.

[0029] During cleaning, air is pumped into the drain trough 2 through its bottom aeration channel 3, aeration holes 31, and jet holes 30. The aeration holes 31 pump air upwards from the bottom of the drain trough 2, maintaining a large-scale turbulent flow in the water. The jet holes 30, in conjunction with the turbulent flow, spray a more concentrated upward impact jet, thus providing a more powerful rinse to the food, effectively removing pesticide residues and dirt from the surface of the items and improving the cleaning effect. Furthermore, the aeration holes 31 on the bottom wall of the drain trough 2 directly pump air into the drain trough 2, without being blocked by the bottom wall, creating a boiling-like turbulent flow within the drain trough 2, further enhancing the cleaning effect.

[0030] Multiple aeration holes 31 are arranged circumferentially around the bottom wall of the draining tank 2, and jet holes 30 are arranged within the circle surrounding the aeration holes 31. This structure is adopted to expand the turbulence range, prevent food from moving around in the draining basket, and improve the cleaning effect.

[0031] The aeration channel 3 includes an orifice-shaped main body arranged around the bottom edge of the drain tank 2. Several aeration holes 31 are spaced apart on the orifice-shaped main body. A jet channel 301 connects the two opposite long sides of the orifice-shaped main body, and several jet holes 30 are spaced apart corresponding to the jet channel 301. This structure creates a more regular and wider-coverage turbulent cleaning area, further improving the cleaning effect.

[0032] The width of the jet channel 301 is smaller than the width of any side of the orifice body. The jet channel 301 needs to supply the jet orifice 30 with a finer impact gas column, and setting its width narrower is beneficial to increasing the impact height of the jet gas.

[0033] A through channel 300 is connected at the midpoint of the two opposite long sides of the mouth-shaped main body. Two dividing ribs 302, extending along the length of the through channel 300 and arranged side-by-side, form a jet channel 301 within the two dividing ribs 302 and an air passage 303 connecting the mouth-shaped main body outside the two dividing ribs 302. A jet channel 301 is also provided on each side of the through channel 300. This structure allows jet airflow to be formed at the center and sides of the bottom of the drain tank 2, improving the coverage of the jet airflow and enhancing the cleaning effect.

[0034] An air inlet 304 for the aeration channel 3 is provided at the center of the bottom of the through channel 300. An aeration hole 31 is provided at the air inlet 304. Two sets of jet channels 301 are distributed on both sides of the air inlet 304. An air passage 303 is used to connect the air coming from the air inlet 304 with the main body of the inlet. This structure facilitates the supply of air to the aeration channel 3 and makes it easy to distribute the gas.

[0035] An air guide pipe 5 with its air outlet facing upwards is installed below the drain tank 2. The outer bottom wall of the drain tank 2 has an assembly port for the upper end of the air guide pipe 5 to be detachably inserted and connected to the aeration channel 3. This assembly port is the aforementioned air inlet 304. The bottom of the outer tank 1 has a partially recessed water-passing area 13, in which at least a portion of the air guide pipe 5 is accommodated. The aeration channel 3 at the bottom of the drain tank 2 is detachably connected to the air guide pipe 5 at the bottom of the outer tank 1, allowing for selection of whether the air passage is connected as needed. The air guide pipe 5 is at least partially located in the water-passing area 13, improving the compactness of the air intake and drainage structures and fully utilizing the space of the food washing tank.

[0036] A filter plate 14 covers the top of the water-passing area 13, and an air guide pipe passes through the filter plate 14 with its upper end protruding above it. The filter plate 14 filters out large impurities, preventing them from entering the water-passing area 13 and causing blockages in the inlet and outlet. Simultaneously, the filter plate 14 allows silt and small impurities to enter, preventing them from entering the drain tank 2 and tumbling with the turbulent flow, thus improving the cleaning effect. The air guide pipe 5 has an L-shaped structure with a horizontal and a vertical portion. The horizontal portion is located in the water-passing area 13, with its inlet extending to the side of the water-passing area 13. The vertical portion passes through the filter plate 14. This structure facilitates the proper installation of the air guide pipe 5, fully utilizes installation space, shortens the air delivery stroke, and improves the aeration effect.

[0037] The cleaning device of this embodiment includes a water tank 4 and the aforementioned food washing tank 100, which is detachably installed in the water tank 4. The length of the water tank 4 in the horizontal direction is greater than its width in the front-to-back direction, so as to provide a large washing space in the horizontal direction to meet the washing needs of long tableware; this structure can shorten the height of the water tank 4, providing conditions for the utilization of the space below the water tank 4. The food washing tank can be laterally moved in the water tank 4 by means of a support edge provided at the top and / or bottom. The side wall of the water tank 4 and the corresponding side of the food washing tank are provided with water inlet and drainage and air inlet structures, and the food washing tank can be connected or separated from the medium port on the side wall of the water tank 4 by the left and right movement of the food washing tank. In the existing combination of the food washing tank with the water tank 4 or the water tank 4 dishwasher, the food washing tank occupies the usable space of the water tank 4. This embodiment provides a food washing tank that can be combined with or separated from the water tank 4. When combined with the water tank 4, it is an electric cleaning tank; when separated from the water tank 4, it reverts to an independent large water tank 4 to meet the different cleaning needs of users.

[0038] A micro-nano bubble generator 01 is installed outside the water tank 4 to provide micro-nano bubble water to the food washing tank. This micro-nano bubble generator 01 is detachably connected to the water source and the water passage area 13 of the food washing tank. Using this structure, micro-nano bubble water can be supplied to the food washing tank to improve purification capacity. The micro-nano bubble water can penetrate the micropores and crevices of fruit and vegetable skins, penetrate and loosen the muscle fibers of meat and seafood, and the micro-nano bubbles adhere tightly to the food, transferring pesticide residues, purines, and dirt from the food to the surface, which then enters the water under the action of aeration-type turbulence, resulting in healthier food. An air pump assembly 02 is installed outside the water tank 4 to supply air to the aeration channel 3. This air pump assembly 02 is detachably connected to the air guide pipe 5 of the food washing tank. This structure facilitates the provision of boiling-type turbulence through the aeration channel 3 to improve the cleaning effect. A drain pump structure 03 is installed outside the water tank 4 to drain the water from the food washing tank. This drain pump structure 03 is detachably connected to the drain pipe and the water passage area 13 of the food washing tank. This structure facilitates the rapid drainage of wastewater and the replacement of fresh washing water, thereby improving cleaning efficiency and cleaning effect.

[0039] In this embodiment, the micro / nano bubble generator 01, air pump assembly 02, and drain pump structure 03 can be independently installed on the outer wall of the water tank 4, or they can be integrated into a single installation module and installed as a whole on the outer wall of the water tank 4 to fully utilize the surrounding space of the water tank 4 and improve space utilization. When using an integrated installation module 6, it is also convenient to provide media ports 200 for docking between the side wall of the water tank 4 and the side wall of the outer tank 1. For example, when the food washing tank 100 is slid to the right to the end of the water tank 4, the media ports can be docked, and the food washing tank can be supplied with water, air, and drained.

[0040] In this embodiment, when cleaning fruits, vegetables, fish, and meat, water is injected into the outer tank 1, and the items to be cleaned are placed in the drain tank 2. The water passes through the bottom of the drain tank 2 and submerges the items. Furthermore, turbulence is formed in the drain tank 2 through the aeration channel 3 and aeration holes 31 to clean the items.

[0041] In this embodiment, the draining tank 2 holds the food. During washing, the draining tank 2 blows air into the draining tank 2 through the aeration channel 3, aeration holes 31, and jet holes 30 at its bottom. The aeration holes 31 blow air from the bottom of the draining tank 2 upwards, maintaining a large-scale turbulent flow pattern in the water. The jet holes 30, in conjunction with the turbulent flow, spray a more concentrated upward impact jet, thereby washing the food more powerfully to forcefully remove pesticide residues and dirt from the surface of the food to be washed, thus improving the washing effect.
