Description

Technical Field

[0001] This invention relates to the field of kitchen sink technology, specifically to a washing device that can be used as a sink and can automatically wash 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 independent washing of fruits and vegetables, the spray nozzles of this fruit and vegetable disposal unit 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 disposal unit, it mainly utilizes the return water jets from the spray arms to provide turbulent water flow for washing fruits and vegetables. However, because fruits and vegetables contain many impurities and sand during the washing process, they are easily carried by the water jets from the spray arms and tumble with the turbulence, affecting not only the turbulence of the water flow but also causing secondary pollution, thus impacting the washing effect.

[0004] Therefore, the current integrated cleaning structure of water tanks and automatic cleaning machines needs further improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cleaning device that improves the cleaning effect by separating impurities such as mud and sand from the turbulent body, thereby always providing stable turbulence, avoiding secondary pollution, and thus improving the cleaning effect.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A cleaning device includes a water tank and a food washing tank disposed in the water tank. The food washing tank includes a tank body and a washing basket disposed in the tank body. The bottom of the tank body is provided with a recessed water inlet area and a filter plate that can filter the water entering the water inlet area. A water outlet is provided on the side of the water inlet area. The bottom of the washing basket is provided with a drain hole. The device also includes an aeration channel and an aeration hole connected to the aeration channel for blowing air into the washing basket. The aeration channel is connected to an air source through an air guide channel.

[0007] This invention features a water inlet area at the bottom of the food washing tank, which allows for both water intake and drainage. The water inlet area is separated from the washing area above by a filter plate. Turbulent water flow is provided by the aeration channels and holes at the bottom of the washing basket. Fine impurities such as mud and sand from the washing process enter the water inlet area through the filter plate and settle there. The filter plate's isolation function stabilizes the flow in the water inlet area, preventing the mud and sand deposited at the bottom from being agitated by the aeration above the filter plate, thus avoiding secondary pollution and maintaining a stable turbulent flow in the washing basket, thereby improving the washing effect.

[0008] Preferably, the inlet area constitutes a sedimentation zone for depositing silt and impurities, and the filter plate constitutes a separator separating the sedimentation zone from the cleaning zone above it. This structure relatively separates the aeration and cleaning 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 providing a stable turbulent flow at all times.

[0009] Preferably, the water outlet is connected to a water inlet and drainage structure located outside the tank body, and the bottom wall of the water inlet area forms a slope that gradually slopes downward from its edge towards the water outlet. This slope can guide the sediment, so that the sediment is flushed into the water inlet area when water is inlet, avoiding accumulation in the gaps, and is discharged through the water outlet in time when draining, so as to achieve zero sediment residue.

[0010] Preferably, an air guide channel is provided below the cleaning basket to connect the air source and the aeration channel, and an air inlet is provided on the side of the water inlet area to connect with the air source. The air guide channel passes through the filter plate and the water inlet area from top to bottom, connecting the aeration channel and the air inlet. This structure facilitates gas supply and improves the space utilization at the bottom of the tank.

[0011] In this invention, the food washing tank is detachably installed in the water tank, and the air inlet is connected to an air supply mechanism located outside the tank. Because the water spray components of existing fruit and vegetable washing machines actually use the same spray arm structure as those of water tank washing machines, and supplying water to the spray components requires the original water supply system of the water tank washing machine, this can only be achieved when a water tank dishwasher is installed simultaneously. However, the water tank dishwasher itself, due to the bottom return and drainage components, suffers from severely limited height and volume, resulting in a limitation on the tank's volume. This invention provides a supply system for supplying water and / or air to the food washing tank on the outer wall of the water tank. The side wall of the food washing tank (corresponding to the water inlet area) has an inlet that can be connected to or disconnected from the supply system. This inlet includes a water outlet and an air inlet. The supply system is a module integrating a water inlet / drainage structure and an air supply mechanism. This invention detachably integrates the food washing tank into the sink. When the food washing tank is needed, it is placed in the sink, and a supply system enables water, air, and water to enter and exit the tank for cleaning. When the food washing tank is not needed, it can be removed from the sink, providing a large cleaning space to meet user needs. The supply system is located on the outer wall of the sink, unlike existing sink dishwashers that occupy space at the bottom of the sink, leaving room for installing other items and improving space utilization.

[0012] Preferably, the bottom wall of the water inlet area is provided with a sand guiding channel that is recessed relative to the slope, extending from the middle of the slope towards the water outlet. Due to the limited assembly space in this invention, the assembly distance between the bottom of the air guiding channel and the bottom wall of the tank is very small, which can easily cause sediment accumulation. The sand guiding channel can actively guide and drain this part of the sediment, avoiding sediment residue.

[0013] Preferably, the depth and / or width of the sand guiding channel gradually decreases along the drainage direction. This structure allows sediment to accumulate in the sand guiding channel, improving the sediment discharge efficiency.

[0014] Further preferably, the bottom of the air guiding channel is arranged at least partially close to the bottom wall of the water inlet area, and the sand guiding channel and the air guiding channel are arranged alternately. The sand guiding channel and the portion of the air guiding channel arranged close to the bottom wall of the water inlet area are arranged in an X-shape. This structure avoids the bottom of the air guiding channel from obstructing a large area of ​​the sand guiding channel, ensuring that the water flow remains unobstructed within the sand guiding channel during drainage, thereby eliminating potential localized silt blockage in the sand guiding channel and improving the silt removal efficiency.

[0015] As an improvement, the bottom wall of the tank forms a guide surface that gradually slopes downward from the edge towards the filter plate. The bottom of the cleaning basket is provided with air blowing holes that are connected to the aeration channel and arranged towards the guide surface to guide the silt towards the filter plate. With this structure, the silt is guided towards the deposition area, further preventing the presence of silt in the cleaning area and its turbulence from affecting the cleaning effect.

[0016] Preferably, the aeration channel includes multiple interconnected horizontal and vertical arms, and the air blowing holes are located near the bottom edge of the washing basket at the intersection of the horizontal and / or vertical arms and / or the junction of the horizontal and vertical arms. The aeration channel of the present invention is distributed in a grid pattern on the bottom wall of the washing basket. This structure improves the aeration and sand removal effects.

[0017] Further improvements include an elliptical air vent at the corner of the bottom of the cleaning basket, and elongated air vents along the horizontal and / or vertical edges of the bottom of the cleaning basket. These elliptical air vents are inclined at a 1-10 degree angle to the bottom wall of the cleaning basket, and / or have a structure that is smaller at the top and larger at the bottom. Four opposing elliptical air vents are located at the corners of the cleaning basket, providing airflow during drainage to forcibly change the direction of water flow and effectively wash away sediment at the edges. This results in better washing of sediment at the edges. The elliptical air vents are designed with openings at the four corners, and are angled 1-10 degrees to the bottom. Their top-to-bottom shape facilitates airflow diffusion. During drainage, air is blown out, increasing the water flow's dynamics and changing its direction. This force of the water flow effectively washes away sediment from the bottom, significantly improving the washing effect compared to simply adding aeration holes. This is primarily due to the increased coverage area, enhanced water agitation, and greater force in removing sediment. While the air vents can also be elongated or circular, the elliptical shape provides better airflow dispersion, whereas elongated or circular vents only blow in one direction, resulting in less diffused airflow. The elongated air vents in the center of the cleaning basket are specifically designed to blow away sediment accumulated around the filter plate, offering better airflow guidance.

[0018] The above-mentioned air vents and the design of the inclined surface and guide surface, etc., are combined to perform low-frequency aeration drying after cleaning, which can accelerate the drying of the bottom and the cavity. The setting position of the filter plate and its cooperation with the inclined surface and guide surface can achieve efficient collection of residue when the drain pump discharges under negative pressure.

[0019] Preferably, the air guide channel is L-shaped, with its horizontal portion positioned in the water inlet area. The end of this horizontal portion is inserted into the air inlet. The air guide channel is constrained to the bottom wall of the water inlet area, and its vertical portion passes through the filter plate with its upper end positioned above the filter plate. The bottom wall of the washing basket has an assembly opening for the upper end of the vertical portion to pass through and extend into the aeration channel. The horizontal and vertical portions of the L-shaped structure have a smooth transition. This structure facilitates gas communication and the installation and assembly of various components. Furthermore, the rational arrangement of the air guide channel within the water inlet area fully utilizes the space of the food washing tank, improving space utilization.

[0020] In this invention, the food washing tank is detachably installed within a water tank. An external supply system for water and / or drainage and / or air intake is provided for the food washing tank, and this supply system is detachably connected to the food washing tank. Existing methods of combining food washing tanks with water tanks or sink dishwashers result in the food washing tank occupying space within the water tank. This invention provides a food washing tank that can be combined with or separated from a water tank. When combined with the water tank, it functions as an electric washing tank; when separated, it reverts to an independent large water tank, thus meeting different user cleaning needs. The detachable connection of the supply system to the food washing tank facilitates its use as an electric washing tank, enabling it to have independent water intake, drainage, and air intake functions, making it convenient to use.

[0021] Compared with the prior art, the advantages of the present invention are as follows: The present invention sets a water inlet area at the bottom of the food washing tank, which can realize water inlet and drainage. The water inlet area is separated from the washing area above by a filter plate. The aeration channel and aeration holes at the bottom of the washing basket provide turbulent water flow. Fine impurities such as mud and sand in the washing process enter the water inlet area through the filter plate and are deposited. They will not be rolled by the turbulent water flow due to aeration, thereby avoiding secondary pollution and maintaining a stable turbulence in the washing basket, thereby improving the washing effect.

Where applicable, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0029] like Figure 1 As shown in Figure 9, the cleaning device of this embodiment includes a water tank 1 and a food washing tank 2 detachably disposed in the water tank 1. A waste 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 disposed in the tank body 21. A recessed water inlet area 23 and a filter plate 24 covering the top of the water inlet area 23 are provided at the bottom of the tank body 21. A water outlet 231 and an air inlet 232 are provided on the side of the water inlet area 23. A drain hole 221, an aeration channel 222 and an aeration hole 223 communicating with the aeration channel 222 are provided on the bottom wall of the washing basket 22. The aeration channel 222 is connected to the air inlet 232 through an air guide channel 25 passing downward through the filter plate 24 and the water inlet area 23.

[0030] This embodiment only provides an air inlet 232 structure located on the side of the water inlet area 23, but it is understood that the air inlet 232 can also be located at the bottom of the water inlet area 23 or other locations.

[0031] With the above structure, the water inlet area 23 is separated from the cleaning area above by the filter plate 24. The aeration channel 222 and aeration holes 223 at the bottom of the cleaning basket 22 provide turbulent water flow. Fine impurities such as mud and sand in the cleaning process enter the water inlet area 23 through the filter plate 24 and are deposited, and will not be rolled up with the turbulent water flow due to aeration.

[0032] The aforementioned inlet area 23 constitutes a sedimentation area for depositing silt and impurities, and the filter plate 24 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, and avoid the adverse effect of clogging the turbulence source, thus providing a stable turbulence at all times.

[0033] The water inlet area 23 can be formed directly on the bottom of the tank 21, or it can be formed on an outer groove 230 surrounding the tank 21. In this embodiment, the water inlet area 23 is formed on an outer groove 230 surrounding the tank 21.

[0034] In this embodiment, the water inlet 231 connects to the water inlet and drainage structure located outside the tank 21. The bottom wall of the water inlet area 23 forms a slope 233 that gradually slopes downward from its edge towards the water inlet 231. This slope 233 can guide the sediment, so that it is flushed into the water inlet area 23 in the water inlet state and avoids accumulation in the gaps, and is discharged in time through the water inlet 231 in the drainage state, so as to achieve zero sediment residue.

[0035] In this embodiment, the air inlet 232 is connected to an air supply mechanism located outside the tank 21. The air supply mechanism can be a fan or an air pump located outside the tank 21. In this embodiment, a fan is preferred. The fan draws outside air into the aeration channel 222 through the air inlet 232 to provide an air source for the aeration channel 222.

[0036] Existing fruit and vegetable washing machines use the same spray arm structure as sink washing machines, and the water supply for the spray components relies on the original sink washing machine's water supply system. This means that the washing machine can only function when a sink dishwasher is installed simultaneously. However, the sink dishwasher itself has limited height due to its bottom return and drainage components, resulting in a limitation on the sink's volume. In this embodiment, the food washing tank 2 is detachably installed within the sink 1. A supply system 100 for water, water, and air intake is installed outside the sink 1, and this supply system 100 is detachably connected to the food washing tank 2. The supply system 100 is preferably installed on the outer wall of the sink 1 to save assembly space. The supply system 100 may include a water inlet valve, a drain pump, and a fan. The water inlet valve and drain pump are connected to the water outlet 231 via pipes, and the fan is connected to the air inlet 232 via a pipe. 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 supply system is detachably connected to the food washing tank, facilitating its use as an electric washing tank with independent water inlet, drainage, and air intake functions, making it convenient to use.

[0037] The food washing tank 2 can be horizontally mounted in the water tank 1 via supports provided at the top and / or bottom. The side walls of the water tank 1 and the corresponding side of the food washing tank 2 are respectively provided with media interfaces 200 for water flow and gas flow. When the food washing tank 2 is slid to the right to the end of the water tank 1, the media interfaces 200 can be connected, allowing for water, gas, and water drainage. In this embodiment, the food washing tank 2 is detachably mounted in the water tank 1. When the food washing tank 2 is needed, it is placed in the water tank 1, and the supply system 100 enables water, gas, and water drainage for cleaning. When the food washing tank 2 is not needed, it can be removed from the water tank 1, providing a large cleaning space to meet user needs. The supply system is located on the outer wall of the water tank 1, unlike existing sink-based dishwashers that occupy space at the bottom of the water tank 1, leaving space below the water tank 1 for installing other items and improving space utilization.

[0038] In this embodiment, as Figure 3 , 7As shown, the bottom wall of the water inlet area 23 is provided with a sand guiding channel 234 that is recessed relative to the inclined surface 233. The sand guiding channel 234 extends from the middle of the inclined surface 233 to the water outlet 231. Due to the limited assembly space in this embodiment, the assembly distance between the bottom of the air guiding channel 25 and the bottom wall of the tank 21 is very small, which can easily cause sediment accumulation. The sand guiding channel 234 can actively guide and drain this part of the sediment to avoid sediment residue.

[0039] The depth and / or width of the aforementioned sand-guiding channel 234 gradually decreases along the drainage direction. Preferably, the bottom of the air-guiding channel 25 is at least partially close to the bottom wall of the water inlet area 23, and the sand-guiding channel 234 and air-guiding channel 25 are arranged alternately. The sand-guiding channel 234 and the portion of the air-guiding channel 25 arranged close to the bottom wall of the water inlet area 23 are arranged in an X-shaped structure. This structure improves the sediment discharge effect.

[0040] In this embodiment, the bottom wall of the tank 21 forms a guide surface 211 that gradually slopes downward from the edge towards the filter plate 24. The bottom of the cleaning basket 22 is provided with air blowing holes 224 that are connected to the aeration channel 222 and arranged towards the guide surface 211, for directing sediment towards the filter plate 24. This structure guides sediment towards the deposition area, further preventing sediment from remaining in the cleaning area and being tumbled by turbulence, thus affecting the cleaning effect.

[0041] The aforementioned aeration channel 222 includes multiple interconnected horizontal arms 2221 and vertical arms 2222. Air vents 224 are located near the bottom edge of the washing basket 22 at the intersection of the horizontal arms 2221 and / or the vertical arms 2222 and / or the junctions of the horizontal and vertical arms 2222. In this embodiment, the aeration channels are distributed in a grid pattern on the bottom wall of the washing basket 22. This structure improves aeration and sand removal efficiency.

[0042] In this embodiment, an elliptical air hole 224a is provided at the corner of the bottom of the cleaning basket 22. Elongated air holes 224b are provided on the horizontal and / or vertical edges of the bottom of the cleaning basket 22. The elliptical air holes 224a are inclined at 1-10 degrees to the bottom wall of the cleaning basket 22, and / or have a structure that is smaller at the top and larger at the bottom. Four opposing elliptical air holes are provided at the corners of the cleaning basket 22. Air is also blown during drainage to forcibly change the direction of water flow, using the water flow to wash away mud and sand at the edges, resulting in better washing of mud and sand at the edges. The elliptical air holes are designed with openings at the four corners, and are inclined at a 1-10 degree angle to the bottom surface, tilting downwards towards the filter plate 24. The elliptical air holes also have a structure that is smaller at the top and larger at the bottom, facilitating airflow diffusion. During drainage, air is blown, increasing the water flow's dynamics and changing its direction. This utilizes the force of the water flow during drainage to wash away the sediment at the bottom, which is much more effective than simply adding aeration holes. This is mainly reflected in the increased coverage area of ​​the wash, increased water agitation, and greater force in removing sediment. While the air holes 224 can also be elongated or circular, the elliptical air holes diffuse the air in all directions, resulting in better water agitation. Elongated or circular holes only blow in one direction, and the gas diffusion is less effective than that of the elliptical air holes. The elongated air hole in the center of the cleaning basket 22 is designed to specifically blow away the sediment accumulated around the filter plate 24; its elongated shape provides better airflow guidance.

[0043] The design and coordination of the air blowing hole 224, inclined surface 233, and guide surface 211, etc., allow for low-frequency aeration drying after cleaning, which can accelerate the drying of the bottom and cavity. The placement of the filter plate 24 and its coordination with the inclined surface 233 and guide surface 211 can achieve efficient collection of residues when the drain pump discharges under negative pressure.

[0044] In this embodiment, the air guide channel 25 is L-shaped. The horizontal portion of the air guide channel 25 is disposed in the water inlet area 23, and the end of the horizontal portion is inserted and connected to the air inlet 232. The air guide channel 25 is locked to the bottom wall of the water inlet area 23 by screws, clips, or other means. The vertical portion of the air guide channel 25 passes through the filter plate 24, and its upper end is located above the filter plate 24. The bottom wall of the cleaning basket 22 has an assembly port 225 for the upper end of the vertical portion to pass through and extend into the aeration channel 222. The horizontal and vertical portions of the L-shaped structure have a smooth transition. The above structure facilitates gas communication and the installation and assembly of various components.

[0045] In this embodiment, a water inlet area 23 is provided at the bottom of the food washing tank 2. The water inlet area 23 can realize water inlet and drainage, and provides assembly space for the air guide channel 25 for air inlet. The water inlet area 23 is separated from the washing area above by a filter plate 24. Turbulent water flow is provided by the aeration channel 222 and aeration holes 223 at the bottom of the washing basket 22. Fine impurities such as mud and sand in the washing process enter the water inlet area 23 through the filter plate 24 and are deposited. They will not be rolled with the turbulent water flow due to aeration, so as not to cause adverse effects on the turbulence source, thus providing a stable turbulence at all times, thereby improving the washing effect.

[0046] The cleaning device of this embodiment can be integrated with other appliances and installed in a cabinet. For example, a built-in dishwasher or water purifier can be installed in the lower part of the cabinet, and the cleaning device of this embodiment can be installed in the upper part of the cabinet. In this arrangement, due to the limited cabinet space, the bottom of the sink is close to the top of the built-in dishwasher, and there is no space to install the water pump system of the sink-type cleaning machine. The supply system 100 integrated into the flat structure of this embodiment does not need to occupy the space under the sink and can be directly installed on the outer wall of the sink 1, making full use of this narrow area and maximizing the use of space.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
