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] ZL201821326601.1, "A Sink-Type Washing Machine with Fruit and Vegetable Washer," discloses a structure that integrates a sink and a sink dishwasher, with a detachable and movable fruit and vegetable washer installed within the sink. While this structure provides convenience for independent washing of fruits and vegetables, the spray nozzles of the fruit and vegetable washer actually use the same spray arm structure as the sink dishwasher, and the water supply to the spray nozzles requires the original sink dishwasher's water supply system. This means that the solution can only be implemented when a sink dishwasher is installed simultaneously. Furthermore, the sink dishwasher itself, due to its bottom return and drainage components, suffers from severe volume limitations in height, still resulting in a limitation on the sink's volume.

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

[0005] The technical problem to be solved by this utility model is to provide a cleaning device that does not affect the independent usable volume of the water tank and can provide an automatic cleaning function, in light of the current state of the technology.

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

[0007] A cleaning device includes a water tank and a food washing tank detachably disposed in the water tank. The outer wall of the water tank is provided with a supply system for supplying water and air to the food washing tank, and the side wall of the food washing tank is provided with an inlet that can be connected to or disconnected from the supply system.

[0008] Existing methods of combining food washing tanks with sinks or sink dishwashers result in the food washing tank occupying the sink's usable space. This utility model provides a food washing tank that can be combined with or separated from the sink. When combined with the sink, it is an electric washing tank; when separated from the sink, it reverts to an independent large sink, thus meeting the different cleaning needs of users.

[0009] Preferably, the supply system is a first installation module integrating water supply and gas supply structures, which is arranged close to the outer wall of the water tank. Setting the integrated water supply, gas supply, and drainage structure as a flat first installation module facilitates installation on the side of the water tank, greatly saving installation space and improving space utilization.

[0010] The sink of this invention has a horizontal length greater than its front-to-back width. This provides a large washing space in the horizontal direction, accommodating the washing of long tableware; the structure also reduces the height of the sink, allowing for better utilization of the space beneath it.

[0011] Preferably, the side wall of the food washing tank is provided with an air inlet and a water outlet near the bottom. The first installation module is provided with an air inlet pipe that can communicate with the air inlet and a water inlet pipe that can communicate with the water outlet. The side wall of the tank has a notch for the air inlet and water outlet to communicate with the corresponding pipes. This structure facilitates the connection of air, water, and drainage channels.

[0012] As a preferred embodiment, the first mounting module is flat and installed on the left or right side wall of the sink. Installing the first mounting module flat on the left or right side wall allows for a sliding connection of the food washing tank, meaning the food washing tank can slide laterally within the sink. When the food washing tank moves to a fixed position, it connects with the first mounting module to automatically wash food; when it moves to other positions, it disconnects from the first mounting module, allowing the entire food washing tank to be removed from the sink and used as an independent fruit and vegetable tray. Whether the first mounting module is located on the left or right side wall of the sink can be determined according to the user's kitchen cabinet installation requirements. In this invention, the inner side wall of the sink has a protruding, laterally extending guide rib, and correspondingly, the side wall of the food washing tank has a guide portion that slides back and forth against the guide rib. This structure enables the food washing tank to slide laterally within the sink.

[0013] As another preferred option, the first mounting module is installed on the rear side wall of the sink. With this installation method, the food washing tank can still be slidably placed in the sink along the side of the sink to facilitate the user in selecting the washing position as needed. However, since the connection point of the flow channel is located on the rear side wall of the sink, the pipe port on the first mounting module needs to be aligned with the notch on the rear side wall of the sink to achieve connection.

[0014] Preferably, the supply system further includes a second mounting module that is flat and arranged close to the rear side wall of the water tank. This second mounting module contains electrical components that can provide power for air intake and water intake respectively. This structure facilitates the provision of power for air and water intake, and allows for modular installation of the corresponding electrical components, simplifying installation and saving installation space.

[0015] Preferably, the electrical components include a fan, the inlet of which is located in the second installation module and the outlet is connected to an air inlet pipe. The electrical components also include a micro / nano bubble water generator, the inlet of which is connected to a water source and the outlet of which is connected to a water inlet pipe. The supply system integrates a drainage structure; the first installation module is provided with a drainage pipe that can communicate with a water outlet; the electrical components also include a drainage pump, the inlet of which is connected to the drainage pipe and the outlet of which is connected to a drain pipe.

[0016] The aforementioned fan provides power for the bubbling cleaning process, while the micro-nano bubble water generator provides micro-nano bubble water as washing water to improve the cleaning effect. The drain pump enables powerful drainage, achieving automatic water intake and drainage with no residual water. By soaking meat and fish in micro-nano bubble water, purines in the tissues are adsorbed and dissolved, and the bubbling turbulence reduces the purine content of the food.

[0017] Preferably, the fan is installed upside down in the second mounting module, i.e., the air inlet faces upwards. Correspondingly, the top wall of the second mounting module has an air outlet arranged with the air inlet. The outlet of the drainage pump is located at its top and connected to a suspended drainage pipe, the outlet of which is connected to a drain pipe. The fan is installed upside down to prevent water backflow from damaging the fan. The front end of the micro-nano bubble water generator is connected to a water inlet valve. The outlet of the drainage pump is located at its top and connected to a suspended drainage pipe to prevent backflow of drainage.

[0018] Preferably, the air inlet pipe has an inverted bowl-shaped, V-shaped, or U-shaped structure, the water inlet pipe is located below the air inlet pipe and also has an inverted bowl-shaped, V-shaped, or U-shaped structure, and the drain pipe is located below the water inlet pipe. The input end of the air inlet pipe, the input end of the water inlet pipe, and the discharge end of the drain pipe are arranged sequentially from top to bottom. The output end of the air inlet pipe is connected to the air inlet, and the output end of the water inlet pipe intersects with the input end of the drain pipe and is connected to the water outlet. During food washing, due to the turbulent water flow in the tank, a small amount of backflow may occur. The above structure is adopted to prevent backflowing water from entering the air inlet pipe and affecting its front air inlet structure, or entering the water inlet pipe and affecting its front water inlet structure.

[0019] Compared with the prior art, the advantages of this utility model are as follows: This utility model detachably installs the food washing tank in the sink. When the food washing tank is needed, it is placed in the sink, and the water and air are introduced into the food washing tank through the supply system to achieve cleaning. When the food washing tank is not needed, it can be removed from the sink, giving the sink a large volume of cleaning space to meet user needs. In addition, the supply system is located on the outer wall of the sink, which does not occupy the space at the bottom of the sink like existing sink dishwashers, leaving space under the sink for installing other items and improving space utilization.

[0020] Furthermore, ultrasonic cleaning removes contaminants through the cavitation effect of high-frequency sound waves, but requires the integration of electrical components (such as ultrasonic transducers) within the fruit and vegetable basket. Prolonged immersion in water can easily lead to short circuits, making it impossible to achieve water-electricity separation and meet the requirement of being able to be separated and combined. Centrifugal cleaning relies on a motor to drive the rotating basket, requiring a power base at the bottom of the water tank, which disrupts the overall structure of the tank. Contaminants can easily remain in the rotating gaps, and high-speed centrifugation can cause water splashing and damage to soft fruits and vegetables. Additionally, the motor and transmission components require high-strength materials for support, significantly increasing manufacturing costs. Jet cleaning relies on a high-pressure water pump to construct a circulating water path, requiring stringent pipe sealing. A return water filtration system must be designed to prevent nozzle clogging, resulting in a complex overall structure. Water pressure fluctuations can lead to unstable cleaning results. Moreover, to achieve the separation and combination functionality of the cleaning tank, all the above technologies require complex interfaces (such as circuit contacts and power bases), increasing disassembly and assembly complexity and electrical safety hazards. Furthermore, the high cost of core components (such as transducers and motors) makes it difficult to simultaneously meet the user's needs for convenience, safety, and economy. This invention completely separates the electrical components from the food washing tank, greatly improving the safety and reliability of the device. Through low-power fan power and airflow technology, combined with the purification function of micro-nano bubble water, it achieves efficient cleaning of fruits and vegetables and meets the cleaning needs of other food items, while simultaneously solving the noise problems associated with high-pressure bubbles and ultrasonic cleaning. Furthermore, it significantly reduces cleaning energy consumption while maintaining the same cleaning effect. Attached Figure Description

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

[0028] Example 1:

[0029] like Figures 1-6 As shown, the cleaning device of this embodiment includes a water tank 1 and a food cleaning tank 2 detachably disposed in the water tank 1. A drain outlet 13 is provided on the bottom wall of the water tank 1. A supply system 100 for supplying water and air to the food cleaning tank 2 is provided on the outer wall of the water tank 1. An inlet that can be connected or disconnected from the supply system 100 is provided on the side wall of the food cleaning tank 2.

[0030] In existing methods of combining the food washing tank 2 with the sink 1 or the dishwasher, the food washing tank 2 occupies the space of the sink 1. This embodiment provides a food washing tank 2 that can be combined with or separated from the sink 1. When combined with the sink 1, it is an electric washing tank. When separated from the sink 1, it reverts to an independent large sink 1 to meet the different cleaning needs of users.

[0031] In this embodiment, the supply system 100 is a first installation module 10 integrating water supply, gas supply, and drainage structures. This first installation module 10 is flat and arranged close to the outer wall of the sink 1. Setting the integrated water supply, gas supply, and drainage structure as a flat first installation module 10 facilitates its installation on the side of the sink 1, significantly saving installation space and improving space utilization. The flat structure mentioned in this embodiment refers to the installation module having a very small thickness in the vertical direction of the sink sidewall, allowing for full utilization of the narrow space between the sink sidewall and cabinets or other appliances for installation.

[0032] In this embodiment, the length of the sink 1 in the horizontal direction is greater than its width in the front-to-back direction. This provides a large washing space in the horizontal direction to accommodate the washing of long tableware; this structure can also shorten the height of the sink 1, providing conditions for the utilization of the space below the sink 1.

[0033] In this embodiment, the side wall of the food washing tank 2 is provided with an air inlet 21 and a water outlet 22 near the bottom. The food washing tank 2 is provided with an air passage and aeration hole connected to the air inlet 21, and a flow channel and water spray hole connected to the water outlet 22, so as to form air blowing and turbulence in the food washing tank 2 to clean the food in the food washing tank 2.

[0034] The first installation module 10 is equipped with an air inlet pipe 101 that connects to the air inlet 21, a water inlet pipe 102 that connects to the water outlet 22, and a drainage pipe 103. The side wall of the water tank 1 has a notch 11 for connecting the air inlet 21 and the water outlet 22 to the corresponding pipes. This structure facilitates the connection of the air inlet, water inlet, and drainage channels.

[0035] In this embodiment, the first installation module 10 is installed on the left or right side wall of the sink 1; in this embodiment, it is installed on the right side wall. Installing the first installation module 10 on the left or right side wall allows for a sliding connection of the food washing tank 2. That is, the food washing tank 2 can slide laterally within the sink 1. When the food washing tank 2 moves to a fixed position, it connects with the first installation module 10, enabling automatic food washing. When the food washing tank 2 moves to other positions, it disconnects from the first installation module 10, allowing the food washing tank 2 to be removed from the sink 1 and used as an independent fruit and vegetable tray. Whether the first installation module 10 is located on the left or right side wall of the sink 1 can be determined according to the installation requirements of the user's kitchen cabinets.

[0036] In this embodiment, the inner sidewall of the water tank 1 is provided with a laterally extending guide rib 12. Correspondingly, the sidewall of the food washing tank 2 is formed with a guide portion 25 that can reciprocate and slide against the guide rib. This structure is adopted to realize the lateral sliding of the food washing tank 2 in the water tank 1. The main body of the food washing tank 2 has a vertically extending sidewall. The bottom of the food washing tank 2 is formed into a bowl-shaped or flat-bottomed pan-shaped structure that smoothly transitions inward from the bottom edge of the sidewall. The connection between the sidewall and the bottom of the food washing tank 2 forms a guide portion 25 that can slide and support the guide rib 12. By placing the guide portion 25 here, that is, moving the support position between the food washing tank 2 and the water tank 1 to the lower part of the food washing tank 2, the sliding stability of the food washing tank 2 can be improved, and the reliability of the food washing tank 2 when bearing weight can be improved.

[0037] The supply system 100 in this embodiment also includes a second mounting module 20, which is flat and arranged close to the rear side wall of the water tank 1. The second mounting module 20 is equipped with electrical components that can provide power for air intake, water intake, and drainage respectively. This structure facilitates the provision of power for air intake, water intake, and drainage, and allows for modular installation of the corresponding electrical components, making installation convenient and saving installation space.

[0038] The aforementioned electrical components include a fan 201, a micro / nano bubble water generator 202, and a drain pump 203. The inlet of the fan 201 is located in the second installation module 20, and its outlet is connected to the air intake pipe 101. The inlet of the micro / nano bubble water generator 202 is connected to a water source, and its outlet is connected to the water intake pipe 102. The inlet of the drain pump 203 is connected to the drain pipe 103, and its outlet is connected to a drain pipe. The fan 201 provides power for air intake, the micro / nano bubble water generator 202 can provide micro / nano bubble water as washing water to improve the cleaning effect, and the drain pump 203 can achieve powerful drainage to ensure no residual water.

[0039] The aforementioned fan 201 is installed upside down in the second mounting module 20, with the air inlet 2011 facing upwards. Correspondingly, the top wall of the second mounting module 20 has an air outlet 2012 arranged with the air inlet. The outlet of the drain pump 203 is located at its top and is connected to a suspended drain pipe 2031, the outlet of which is connected to a drain pipe. The fan 201 is installed upside down to prevent water backflow from damaging it. The front end of the micro-nano bubble water generator 202 is connected to a water inlet valve. The outlet of the drain pump 203 is located at its top and is connected to a suspended drain pipe 2031 to prevent backflow of drainage.

[0040] In this embodiment, the air inlet pipe 101 has an inverted bowl-shaped, V-shaped, or U-shaped structure. The water inlet pipe 102 is located below the air inlet pipe 101 and also has an inverted bowl-shaped, V-shaped, or U-shaped structure. The drain pipe 103 is located below the water inlet pipe 102. The drain pipe 103 can be arranged with its height gradually decreasing in the drainage direction. The input end of the air inlet pipe 101, the input end of the water inlet pipe 102, and the discharge end of the drain pipe 103 are arranged sequentially from top to bottom. The output end of the air inlet pipe 101 is connected to the air inlet 21, and the output end of the water inlet pipe 102 intersects with the input end of the drain pipe 103 and is connected to the water outlet 22. During food washing, due to the turbulent water flow in the tank, a small amount of backflow may occur. The above structure is adopted to prevent backflow water from entering the air inlet pipe 101 and affecting its front air intake structure, or entering the water inlet pipe 102 and affecting its front water intake structure.

[0041] In this embodiment, the food washing tank 2 is detachably installed in the sink 1. When the food washing tank 2 is needed, it is placed in the sink 1, and water and air are introduced into the food washing tank 2 through the supply system 100 to achieve cleaning. When the food washing tank 2 is not needed, it can be removed from the sink 1, so that the sink 1 has a large volume of cleaning space to meet user needs. In addition, the supply system 100 is located on the outer wall of the sink 1, so as not to occupy the space at the bottom of the sink 1 like existing sink 1 dishwashers, leaving space under the sink 1 to install other items and improving space utilization.

[0042] Example 2:

[0043] The difference between this embodiment and Embodiment 1 is that:

[0044] The first mounting module 10 is mounted on the rear wall of the water tank 1. Since the second mounting module 2 is also mounted on the rear wall of the water tank 1, the inlet of the first mounting module 10 and the outlet of the second mounting module 2 are connected. In order to shorten the fluid travel, the connection between the two can be a shorter horizontal pipe connection.

[0045] Using the above installation method, the food washing tank 2 can still be slidably installed in the water tank 1 along the side of the water tank 1, so that users can choose the washing position as needed. However, since the connection point of the flow channel is located on the rear side wall of the water tank 1, the pipe port on the first installation module 10 needs to be aligned with the notch 11 on the rear side wall of the water tank 1 before the connection can be achieved.

[0046] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
