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 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 arm to provide turbulent water flow for washing fruits and vegetables. However, due to the limitations of the spray arm's nozzle structure, the turbulence pattern is limited, failing to meet the washing needs of different ingredients, thus significantly affecting the washing effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cleaning device that can select the appropriate turbulent cleaning method according to different ingredients, thereby improving the cleaning effect, 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 detachable food washing tank disposed within the water tank. The food washing tank includes a tank body and a washing basket disposed within the tank body. The bottom of the washing basket is provided with a drain hole, an aeration channel, and an aeration hole. The aeration channel includes a relatively independent first aeration channel and a second aeration channel. The aeration hole includes a first aeration hole connected to the first aeration channel and spraying air upwards from the bottom wall of the washing basket, and a second aeration hole connected to the second aeration channel and used to create circumferential turbulence in the washing basket.

[0007] In the non-cleaning state, both the first aeration channel and the second aeration channel are isolated from the air source;

[0008] In the first cleaning state, the first aeration channel is connected to the air source, the second aeration channel is isolated from the air source, and a boiling turbulent flow is formed in the cleaning basket, which is sprayed from the bottom wall of the cleaning basket through the first aeration hole from bottom to top.

[0009] In the second cleaning state, both the first aeration channel and the second aeration channel are connected to the air source. A boiling turbulent flow is formed in the cleaning basket, which is sprayed from the bottom wall of the cleaning basket through the first aeration hole from bottom to top. At the same time, an annular turbulent flow is formed in the cleaning basket, which is sprayed through the second aeration hole.

[0010] In the third cleaning state, the first aeration channel is isolated from the air source, the second aeration channel is connected to the air source, and an annular turbulence is formed in the cleaning basket through the second aeration hole.

[0011] In this invention, the air flow rate in the first cleaning state is A, the air flow rate in the second cleaning state is B, and the air flow rate in the third cleaning state is C, where A < B < C. In this invention, the switching and coordination between boiling turbulence and annular turbulence is achieved by the aeration structure in conjunction with the air intake, thus meeting more cleaning requirements.

[0012] Preferably, the first aeration channel includes at least an orifice-shaped structure arranged around the edge of the bottom wall of the washing basket, and the first aeration holes are multiple, with corresponding orifice-shaped structures spaced apart on the inner bottom wall of the washing basket. Using the above structure, the first aeration channel and second aeration holes of this invention mainly create a boiling-type turbulent flow over a large area at the bottom of the washing basket, and the turbulence intensity is not too high, which is beneficial for improving the washing effect for leafy vegetables.

[0013] Preferably, the second aeration channel is at least partially annular and distributed within the orifice-shaped structure, and the second aeration holes are multiple and arranged at intervals and at an angle to the corresponding annular structure on the inner bottom wall of the washing basket. Using this structure, a specific annular turbulent flow region is formed on the bottom wall of the washing basket, allowing the food to flow in a wide range of annular patterns. For blocky food items, this further improves the washing effect.

[0014] Preferably, the annular structure consists of two layers, inner and outer, which are connected. The bottom wall of the cleaning basket is provided with second aeration holes corresponding to the two annular structures, and the cleaning trend of each second aeration hole is the same. When the length of the cleaning basket is large, two or more annular structures can be arranged side by side to further improve the cleaning effect.

[0015] Preferably, the first aeration channel further includes an auxiliary channel connecting the two opposite sides of the orifice-shaped structure, and the inner bottom wall of the cleaning basket has a second aeration hole corresponding to and communicating with the auxiliary channel. This structure increases the coverage area when only boiling turbulent cleaning is used, and also improves the overall cleaning effect when boiling turbulence is combined with annular turbulence.

[0016] Preferably, the bottom wall of the washing basket has a first air inlet communicating with a first aeration channel and a second air inlet communicating with a second aeration channel. Below the washing basket is an air guide pipe for supplying air to the first and second air inlets. This air guide pipe has a first air guide channel and a second air guide channel corresponding to the first and second air inlets, respectively. The upper end of the first air guide channel forms a first plug that can be detachably inserted into the first air inlet, and the upper end of the second air guide channel forms a second plug that can be detachably inserted into the second air inlet. This structure facilitates the detachable connection between the tank and the washing basket. After washing, the washing basket can be directly used as a drain basket to remove the food, which is very convenient.

[0017] Preferably, the air guide pipe is located at the bottom of the tank and has a Y-shaped structure. The two branches of the Y-shaped structure respectively form a first air guide channel and a second air guide channel. A partition is provided in the lower part of the Y-shaped structure to separate and communicate with the corresponding branches. The lower part of the Y-shaped structure extends to the side wall of the food washing tank. An air supply mechanism is provided outside the tank. A notch is provided in the side wall of the tank to connect the air supply mechanism with the air guide pipe of the food washing tank. The above structure facilitates gas diversion and allows for a detachable connection between the food washing tank and the water tank. When the food washing tank is needed, it is placed in the water tank and connected to the supply mechanism via an air guide pipe, enabling automatic air intake and aeration cleaning. When the food washing tank is not needed, it can be removed from the water tank, providing a large cleaning space to meet user needs. This invention can also include a water guide pipe connecting the tank body to the external inlet and outlet drainage structure. This water guide pipe, like the air guide pipe, extends to the side of the tank body and connects to the inlet and outlet drainage structure via a detachable interface, enabling automatic inlet and outlet drainage of the food washing tank.

[0018] Preferably, the outer wall of the water tank is provided with a first air supply channel connected to the first air guide channel and a second air supply channel connected to the second air guide channel. The air inlet ends of the first and second air supply channels are connected to the air supply mechanism through control valves. The control valves are used to control whether the first and second air supply channels are connected to the air supply mechanism. This structure facilitates switching the cleaning mode of the cleaning basket by controlling the airflow connection.

[0019] Preferably, an airflow distribution chamber is provided on the air outlet end of the air supply mechanism. The first air delivery channel and the second air delivery channel are stacked and connected to the airflow distribution chamber from the side. The control valve is axially movable within the airflow distribution chamber and has an opening that can move axially with the airflow rate to determine whether it connects with the first and second air delivery channels. Preferably, the control valve includes a valve body. One end of the valve body facing the supply mechanism forms an air inlet chamber. The second end of the valve body is elastically connected to the end of the airflow distribution chamber via an elastic element. The opening is located on the side wall of the valve body and communicates with the air inlet chamber. With the above structure, the cleaning mode can be automatically switched by changing the airflow size. The structure is simple and reliable.

[0020] Preferably, when the air supply mechanism is not in operation, the valve body moves towards the air supply mechanism until its side wall closes the inlet ends of the first and second air supply channels. As the air supply volume of the air supply mechanism increases, the valve body moves in the opposite direction until its opening aligns with the inlet end of the first air supply channel, opening the first air supply channel and closing the inlet end of the second air supply channel with its side wall. As the air supply volume of the air supply mechanism continues to increase, the valve body moves in the opposite direction until its opening aligns with the inlet ends of the first and second air supply channels, opening both channels. As the air supply volume of the air supply mechanism increases further, the valve body moves in the opposite direction until its opening aligns with the inlet end of the second air supply channel, opening the second air supply channel and closing the inlet end of the first air supply channel with its side wall. This structure allows for control of different switching modes of the cleaning basket by changing the airflow volume.

[0021] Compared with the prior art, the advantages of this utility model are as follows: This utility model detachably mounts the food washing tank in the water tank. When the food washing tank is needed, it is placed in the water tank, and automatic air intake and aeration cleaning are achieved by controlling whether the aeration channel is connected or not. When the food washing tank is not needed, it can be removed from the water tank, giving the water tank a large volume of cleaning space to meet user needs. This utility model has two different aeration hole structures set at the bottom of the washing basket, which realize the switching and coordination of boiling turbulence and annular turbulence, respectively, so as to select the appropriate turbulence cleaning method according to different ingredients, thereby improving the cleaning effect.

[0040] like Figures 1-11 As shown, the cleaning device in this embodiment includes a water tank 1 and a food cleaning tank 2 detachably installed in the water tank 1. The bottom of the water tank 1 is provided with a waste outlet 13. The food cleaning tank 2 includes a tank body 21 and a cleaning basket 22 installed in the tank body 21. The bottom of the cleaning basket 22 is provided with a drain hole 221, an aeration channel and an aeration hole. The aeration channel includes a relatively independent first aeration channel 222 and a second aeration channel 223. The aeration hole includes a first aeration hole 224 connected to the first aeration channel 222 and spraying upwards from the bottom wall of the inner wall of the cleaning basket 22, and a second aeration hole 225 connected to the second aeration channel 223 and used to form circumferential turbulence in the cleaning basket 22.

[0041] The food cleaning method in this embodiment is as follows:

[0042] In the non-cleaning state, both the first aeration channel 222 and the second aeration channel 223 are isolated from the air source;

[0043] In the first cleaning state, the first aeration channel 222 is connected to the air source, the second aeration channel 223 is isolated from the air source, and a boiling turbulent flow is formed in the cleaning basket 22, which is sprayed from the bottom wall of the cleaning basket 22 through the first aeration hole 224 from bottom to top.

[0044] In the second cleaning state, both the first aeration channel 222 and the second aeration channel 223 are connected to the air source. A boiling turbulent flow is formed in the cleaning basket 22, which is sprayed from the bottom wall of the cleaning basket 22 through the first aeration hole 224 from bottom to top. At the same time, an annular turbulent flow is formed in the cleaning basket 22, which is sprayed through the second aeration hole 225.

[0045] In the third cleaning state, the first aeration channel 222 is isolated from the air source, and the second aeration channel 223 is connected to the air source. An annular turbulence is formed in the cleaning basket 22, which is sprayed through the second aeration hole 225.

[0046] In this embodiment, the air flow rate is A in the first cleaning state, B in the second cleaning state, and C in the third cleaning state, where A < B < C. In this embodiment, the switching and coordination between boiling turbulence and annular turbulence is achieved by the aeration structure in conjunction with the air intake, to meet more cleaning requirements.

[0047] The first aeration channel 222 includes at least an orifice structure 226 arranged around the edge of the bottom wall of the washing basket 22. Multiple first aeration holes 224 are arranged at intervals on the inner bottom wall of the washing basket 22, corresponding to the orifice structures 226. Using this structure, the first aeration channel 222 and the second aeration holes 225 in this embodiment mainly create a large-area boiling-type turbulence at the bottom of the washing basket 22, and the turbulence intensity is not too high, which is beneficial for improving the washing effect for leafy vegetables.

[0048] The second aeration channel 223 is at least partially annular in structure 227 and distributed within the orifice structure 226. Multiple second aeration holes 225 are arranged at intervals and at an angle to the corresponding annular structure 227 on the inner bottom wall of the washing basket. Using this structure, a specific annular turbulent flow zone is formed on the bottom wall of the washing basket 22, allowing the food to flow in a wide range of annular patterns. For blocky food items, this further improves the washing effect.

[0049] The annular structure 227 consists of two layers, inner and outer, which are connected. The bottom wall of the cleaning basket 22 is provided with second aeration holes 225 corresponding to the two annular structures 227, and the cleaning trend of each second aeration hole 225 is the same. When the length of the cleaning basket 22 is large, two or more annular structures 227 can be arranged side by side to further improve the cleaning effect.

[0050] The first aeration channel 222 also includes an auxiliary channel 228 connecting the two opposite sides of the orifice structure 226. The inner bottom wall of the cleaning basket 22 has a second aeration hole 225 that corresponds to and communicates with the auxiliary channel 228. With this structure, the coverage area can be increased when only boiling turbulent cleaning is used, and the overall cleaning effect can be improved when boiling turbulence and annular turbulence are combined.

[0051] The bottom wall of the washing basket 22 has a first air inlet 22a connected to the first aeration channel 222 and a second air inlet 22b connected to the second aeration channel 223. Below the washing basket 22 is an air guide pipe 3 for supplying air to the first air inlet 22a and the second air inlet 22b. This air guide pipe 3 has a first air guide channel 31 and a second air guide channel 32 corresponding to the first air inlet 22a and the second air inlet 22b, respectively. The upper end of the first air guide channel 31 forms a first plug 311 that can be detachably inserted into the first air inlet 22a, and the upper end of the second air guide channel 32 forms a second plug 321 that can be detachably inserted into the second air inlet 22b. This structure facilitates the detachable connection between the tank 21 and the washing basket 22. After washing, the washing basket 22 can be directly used as a drain basket to remove food, which is very convenient.

[0052] The air guide pipe 3 is located at the bottom of the tank 21 and has a Y-shaped structure. The two branches of the Y-shaped structure respectively form the first air guide channel 31 and the second air guide channel 32. The lower part of the Y-shaped structure is provided with a partition 33 that can separate and communicate with the corresponding branches. The lower part of the Y-shaped structure extends to the side wall of the food washing tank 2. An air supply mechanism 5 is provided outside the water tank 1. The side wall of the water tank 1 is provided with a notch 10 that connects the air supply mechanism 5 with the air guide pipe 3 of the food washing tank 2. The above structure facilitates gas diversion and enables a detachable connection between the food washing tank 2 and the water tank 1. When the food washing tank 2 is needed, it is placed in the water tank 1 and connected to the supply mechanism through the air guide pipe 3, enabling automatic air intake and aeration cleaning. When the food washing tank 2 is not needed, it can be removed from the water tank 1, giving the water tank 1 a large cleaning space to meet user needs. This embodiment can also be equipped with a water guide pipe that connects the tank body 21 to the external water inlet and drainage structure. This water guide pipe can extend to the side of the tank body 21 like the air guide pipe 3 and connect to the water inlet and drainage structure through a detachable interface, enabling automatic water inlet and drainage of the food washing tank 2.

[0053] The outer wall of the water tank 1 is provided with a first air supply channel 01 connected to the first air guide channel 31 and a second air supply channel 02 connected to the second air guide channel 32. The air inlet ends of the first air supply channel 01 and the second air supply channel 02 are connected to the air supply mechanism 5 (a fan in this embodiment) through a control valve 4. The control valve 4 is used to control whether the first air supply channel 01 and the second air supply channel 02 are connected to the air supply mechanism 5. The above structure makes it easy to switch the cleaning mode of the cleaning basket 22 by controlling whether the airflow is connected.

[0054] An air distribution chamber 51 is provided on the air outlet end of the air supply mechanism 5. A first air delivery channel 01 and a second air delivery channel 02 are stacked and connected to the side of the air distribution chamber 51. A control valve 4 is axially movable within the air distribution chamber 51. The control valve 4 has an opening 41 that can move axially with changes in air flow rate, thus controlling whether it connects with the first air delivery channel 01 or the second air delivery channel 02. The control valve 4 includes a valve body 42. One end of the valve body 42 facing the supply mechanism forms an air inlet chamber 421. The second end of the valve body 42 is elastically connected to the end of the air distribution chamber 51 via an elastic member 43. The opening 41 is located on the side wall of the valve body 42 and communicates with the air inlet chamber 421. Using this structure, the cleaning mode can be automatically switched by changing the airflow volume. The structure is simple and reliable.

[0055] When the gas supply mechanism 5 is not in operation, the valve body 42 moves toward the gas supply mechanism 5 until its side wall closes the inlet ends of the first gas supply channel 01 and the second gas supply channel 02. As the gas supply of the gas supply mechanism 5 increases, the valve body 42 moves in the opposite direction until the opening 41 aligns with the inlet end of the first gas supply channel 01, thus opening the first gas supply channel 01, and the side wall of the valve body 42 closes the inlet end of the second gas supply channel 02. As the gas supply of the gas supply mechanism 5 continues to increase, the valve body 42 moves in the opposite direction until the opening 41 aligns with the inlet ends of the first gas supply channel 01 and the second gas supply channel 02, thus opening the first gas supply channel 01 and the second gas supply channel 02. As the gas supply of the gas supply mechanism 5 increases again, the valve body 42 moves in the opposite direction until the opening 41 aligns with the inlet end of the second gas supply channel 02, thus opening the second gas supply channel 02, and the side wall of the valve body 42 closes the inlet end of the first gas supply channel 01. The above structure is used to control different switching modes of the cleaning basket 22 by changing the airflow magnitude.

[0056] 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 automatic air intake and aeration cleaning are achieved by controlling whether the aeration channel is connected or not. 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 user needs. In this embodiment, two different aeration hole structures are set at the bottom of the washing basket 22 to realize the switching and coordination of boiling turbulence and annular turbulence, so as to select the appropriate turbulence cleaning method according to different ingredients, thereby improving the cleaning effect.

[0057] 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.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

The control valve has an opening that can move axially with the air flow rate to determine whether it is connected to the first air delivery channel or the second air delivery channel.

11. The cleaning apparatus of claim 10, wherein: The control valve includes a valve body, with an air inlet chamber formed at one end of the valve body facing the supply mechanism. The second end of the valve body is elastically connected to the end of the airflow distribution chamber via an elastic element. The opening is located on the side wall of the valve body and communicates with the air inlet chamber.

12. The cleaning apparatus of claim 11, wherein: When the gas supply mechanism is not in operation, the valve body moves toward the gas supply mechanism until its side wall closes the inlet ends of the first and second gas supply channels; as the gas supply volume of the gas supply mechanism increases, the valve body moves in the opposite direction until its opening aligns with the inlet end of the first gas supply channel, thus opening the first gas supply channel and the side wall of the valve body closes the inlet end of the second gas supply channel; as the gas supply volume of the gas supply mechanism continues to increase, the valve body moves in the opposite direction until its opening aligns with the inlet ends of the first and second gas supply channels, thus opening the first and second gas supply channels. As the gas supply from the gas supply mechanism increases, the valve body moves in the opposite direction until its opening aligns with the inlet end of the second gas supply channel, thus opening the second gas supply channel and closing the inlet end of the first gas supply channel with the side wall of the valve body.
