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 that are connected to the aeration channel. The side wall of the draining tank is also provided with a jet nozzle that is connected to the aeration channel and can reciprocate along the length of the draining tank as the air pressure in the aeration channel changes.

[0008] During cleaning, the draining tank blows air into the tank through its bottom aeration channels and aeration holes, performing a boiling-style cleaning of the food. At the same time, by changing the air pressure in the aeration channels, the jet nozzles move back and forth along the length of the draining tank, providing a targeted impact-style turbulent water jet from the side of the draining tank. Combined with the aeration holes, which provide large-area aeration from bottom to top, the food in the draining tank is cleaned from all angles, thoroughly removing pesticide residues and dirt from the surface of the items to be cleaned, thus improving the cleaning effect.

[0009] Preferably, the sidewall of the drain trough is provided with a channel extending laterally along its length. One end of the channel forms an air chamber that extends downward and communicates with an aeration channel located on the bottom wall of the drain trough. The inner sidewall of the drain trough has a groove communicating with the channel. The air nozzle is reciprocally constrained in the groove, with its inlet end communicating with the air chamber and its outlet end facing into the drain trough. This structure facilitates air supply to the air nozzle and enables stable lateral reciprocating movement of the air nozzle.

[0010] Preferably, the slide groove is provided with a telescopic tube arranged near its first end and communicating with the air chamber. The air nozzle is connected to the inner end of the telescopic tube and tends to extend towards the second end of the slide groove along with the telescopic tube. The slide groove is also provided with an elastic element that can abut against the air nozzle, thereby keeping the telescopic tube tending to contract. The above-mentioned telescopic tube is a plastic telescopic tube, and a spiral steel wire can be embedded inside the tube. The tube is generally inclined to extend, but it can contract axially when subjected to axial pressure. With the above structure, when the air pressure changes, the extension of the telescopic tube and the reciprocating movement of the nozzle can be achieved by reverse squeezing the air nozzle.

[0011] Preferably, the outer end of the jet nozzle is provided with a first limiting post extending laterally, and correspondingly, the second end of the slide groove is provided with a second limiting post. The elastic element is a spring with its two ends respectively sleeved outside the first limiting post and the second limiting post. This structure improves reliable support for the extension of the elastic element.

[0012] Preferably, the bottom of the jet nozzle is provided with a downwardly extending guide post, and correspondingly, the bottom wall of the chute is provided with a guide groove extending along its length and cooperating with the guide post. This structure guides and radially limits the jet nozzle, ensuring stable and reliable lateral movement while preventing circumferential rotation that could affect the jet direction.

[0013] Preferably, the jet nozzles are in two sets and are respectively disposed on two opposite sidewalls of the drain tank, and the two jet nozzles move in opposite directions as the air pressure in the aeration channel changes. This structure provides a larger spray coverage area and improves the cleaning effect.

[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 and aeration holes at the bottom, performing a boiling-style cleaning of the food. At the same time, the air pressure in the aeration channel can be changed to make the jet nozzle move back and forth along the length of the draining tank, providing a targeted impact-type turbulent water column from the side of the draining tank. Combined with the aeration holes, the air is aerated from bottom to top over a large area, so as to clean the food in the draining tank in all directions, so as to completely remove pesticide residues and dirt from the surface of the items to be cleaned, thereby improving the cleaning effect.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1-9As 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 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 that are connected to the aeration channel 3. The side wall of the draining tank 2 is also provided with a jet nozzle 8 that is connected to the aeration channel 3 and can move back and forth along the length of the draining tank 2 as the air pressure in the aeration channel 3 changes.

[0030] During cleaning, the draining tank 2 blows air into it through the aeration channel 3 and aeration holes 31 at its bottom, performing a boiling-style cleaning of the food. At the same time, the air pressure in the aeration channel 3 can be changed to make the jet nozzle 8 move back and forth along the length of the draining tank 2, providing a targeted impact-style turbulent water column from the side of the draining tank 2. Combined with the aeration holes 31, the air is aerated from bottom to top over a large area, cleaning the food in the draining tank 2 in all directions, so as to completely remove pesticide residues and dirt from the surface of the items to be cleaned and improve the cleaning effect.

[0031] The sidewall of the drain trough 2 is provided with a channel 22 extending laterally along its length. One end of the channel 22 forms an air chamber 30 that extends downward through an air guide arm 301 and communicates with an aeration channel 3 located on the bottom wall of the drain trough 2. The inner sidewall of the drain trough 2 is provided with a groove 300 that communicates with the channel 22. The nozzle 8 is reciprocally constrained in the groove 300, with its air inlet end communicating with the air chamber 30 and its air outlet end facing into the drain trough 2. With the above structure, it is convenient to supply air to the nozzle 8 and enable the nozzle 8 to make stable lateral reciprocating movements.

[0032] A telescopic tube 9 is arranged near its first end and connected to the air chamber 30 in the chute 300. An air nozzle 8 is connected to the inner end of the telescopic tube 9 and tends to extend towards the second end of the chute 300 along with the telescopic tube 9. An elastic element 91 is also provided in the chute 300 to abut against the air nozzle 8, thereby maintaining the contraction tendency of the telescopic tube 9. The telescopic tube 9 is a plastic telescopic tube 9, and a spiral steel wire can be embedded inside the tube. It has an overall extending tendency, but can undergo axial contraction under axial pressure. Using this structure, when the air pressure changes, the telescopic tube 9 can be extended by reverse compression of the air nozzle 8, and the nozzle can reciprocate.

[0033] The outer end of the jet nozzle 8 is provided with a first limiting post 81 extending laterally, and correspondingly, the second end of the slide groove 300 is provided with a second limiting post 82. The elastic element 91 is a spring with its two ends respectively sleeved on the first limiting post 81 and the second limiting post 82. The above structure is adopted to improve the reliable support for the extension of the elastic element 91.

[0034] The bottom of the nozzle 8 is provided with a downwardly extending guide post 83, and correspondingly, the bottom wall of the slide 300 is provided with a guide groove 84 extending along its length and cooperating with the guide post 83. This structure is used to guide the nozzle 8 and limit its radial movement, so that the nozzle 8 can move laterally stably and reliably, while avoiding its circumferential rotation from affecting the spray direction.

[0035] Two sets of jet nozzles 8 are respectively installed on two opposite side walls of the drain tank 2. The two jet nozzles 8 move in opposite directions as the air pressure in the aeration channel 3 changes. This structure provides a larger spray coverage area and improves the cleaning effect.

[0036] 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 302 for the upper end of the air guide pipe 5 to be detachably inserted into it, thus connecting it to the aeration channel 3. 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 or not 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 making full use of the space in the food washing tank.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.
