Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and more particularly to an automatic cleaning device. Background Technology

[0002] As people's living standards continue to improve, multi-functional washing sinks are increasingly becoming a common kitchen appliance. Currently, multi-functional washing sinks on the market typically have a function switching component at the bottom to clean dishes, fruits, and vegetables. This component generates bubbles that adhere to the surface of the food being treated, and the cavitation effect created when these bubbles burst removes dirt and grime from the surface.

[0003] To avoid wasting time and breeding bacteria by letting the tub air dry after washing, multi-functional washing tanks usually include a function switching component, which uses a fan to blow hot air into the tank through vents. However, the function switching components occupy a lot of space, and functional holes connected to the components need to be set in the bottom plate of the washing tank, resulting in a complex bottom plate structure and increased cost. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cleaning device. By setting a heating element in the flow channel, the drying function and the air blowing function share the flow channel, air passage and air hole, which reduces the space occupied, simplifies the structure of the cleaning box and reduces the cost.

The flow channel is located below the cleaning space and is connected to the air passage. A heating element is installed inside the flow channel, and the fan drives air into the flow channel. When the heating element is activated, the function switching component dries the objects in the cleaning space; when the heating element is deactivated, the function switching component blows air into the cleaning space.

A drive spray hole is provided on the bottom surface of the spray arm and is connected to the water supply channel. In the circumferential direction of the rotation of the spray arm, along the downward direction, the spray direction of the drive spray hole is tilted backward so that the reaction force of the spray water flow from the drive spray hole drives the spray arm and the rotating shaft to rotate.

[0008] Preferably, the bottom surface of the spray arm is provided with a plurality of cleaning spray holes, and the plurality of cleaning spray holes are connected to the water supply channel.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] This invention provides an automatic cleaning device, such as... Figures 1-5 As shown, the automatic cleaning device includes a cleaning tank 1, a top cover 3, and a function switching component 2. The top cover 3 is fastened to the cleaning tank 1 to form a cleaning space 12. The bottom of the cleaning space 12 is provided with a drain hole 19 and a circulation air channel 14. The bottom of the cleaning space 12 is provided with a vent hole 143 corresponding to the circulation air channel 14 and communicating with the circulation air channel 14. The cleaning space 12 contains the object to be processed. The function switching component 2 includes a fan 21, a guide channel 23, and a heating element 22. The guide channel 23 is located below the cleaning space 12 and is connected to the circulation air channel 14. The heating element 22 is provided in the guide channel 23. The fan 21 drives air into the guide channel 23. When the heating element 22 is activated, the function switching component 2 dries the object in the cleaning space 12. When the heating element 22 is deactivated, the function switching component 2 blows air into the cleaning space 12.

[0024] In this automatic cleaning device, the cleaning tank 1 is used to hold the items to be processed. The top cover 3 is fastened to the cleaning tank 1 to form a closed cleaning space 12. When cleaning the items, the heating element 22 is turned off, and the fan 21 of the function switching component 2 drives air into the airflow channel 14, forming bubbles through the vent 143, which then enter the cleaning space 12. As the bubbles rise in the water, they come into contact with the lower surface of the items. When the bubbles burst on the surface of the items, they create a cavitation effect, and the resulting impact force can peel off dirt from the surface of the items within a small area. After cleaning, the water in the cleaning space 12 is drained through the drain hole 19, and the heating element 22 is activated. The heating element 22 heats the air, and the fan 21 drives the air into the guide channel 23, which then enters the cleaning space 12 through the vent 143 of the airflow channel 14 to dry the cleaned items.

[0025] The automatic cleaning device reduces the space occupied by setting a heating element 22 in the flow channel 23, so that the drying function and the air blowing function share the flow channel 23, the air passage 14 and the air vent 143, and simplifies the structure of the support plate 11, thereby reducing the cost.

[0026] The items to be processed can be food or tableware to be washed. After washing, the items to be processed become items to be dried. For ease of understanding, they will be referred to as items to be processed below.

[0027] In this embodiment, the cleaning tank 1 also includes a support plate 11 that serves as the bottom plate of the cleaning space 12. Drainage holes 19, air passages 14 and multiple ventilation holes 143 are all provided on the support plate 11. The flow channel 23 and the water pump 41 are provided below the support plate 11.

[0028] In some embodiments, the flow channel 23 includes two branches, both of which are connected to the fan 21 and the air passage 14, and the heating element 22 is disposed in one of the branches. A switching element is disposed in the flow channel 23, which can selectively block one of the branches.

[0029] It is understandable that hot air or bubbles will flow upward after entering the cleaning space 12 through the vent 143. If the hot air or bubbles are not evenly distributed in the cleaning space 12, it will cause the object to be treated to dry quickly or even overheat, or the bottom of the object to be treated may not be able to fully contact the bubbles, affecting the treatment effect.

[0030] like Figures 1-6As shown, to solve the above problems, the air passage 14 includes a main air passage 141 and multiple branch air passages 142 connected to the main air passage 141. The main air passage 141 includes an air inlet 151, a guide channel 23 connected to the air inlet 151, and a fan 21 connected to the guide channel 23. The multiple branch air passages 142 are spaced apart along the extension direction of the main air passage 141 and extend in a direction away from the main air passage 141. Along the extension direction of the branch air passages 142, the bottom of the cleaning space 12 (i.e., the support plate 11) is provided with multiple ventilation holes 143 corresponding to each branch air passage 142.

[0031] In this automatic cleaning device, the cleaning tank 1 is divided into two parts by a support plate 11. A cleaning space 12 is formed above the support plate 11, and an installation space 13 is formed below the support plate 11 for installing the function switching component 2. The air passage 14 of the support plate 11 includes multiple branch air passages 142 and a main air passage 141 that connects the multiple branch air passages 142 to supply air to the multiple branch air passages 142. The function switching component 2 drives air into the main air passage 141 through a fan 21. The air entering the main air passage 141 can flow along the main air passage 141 and enter the multiple branch air passages 142 that are connected to the main air passage 141, and then enter the cleaning space 12 through the vent holes 143 of the branch air passages 142. Since multiple branch airways 142 are spaced apart along the extension direction of the main airway 141 and extend away from the main airway 141, the vents 143 of the multiple branch airways 142 are widely distributed on the support plate 11, so that the hot air or bubbles entering the cleaning space 12 are evenly distributed, ensuring the consistency of the treatment effect.

[0032] In addition, the top cover 3 can cover the washing space 12, so that the hot air entering the washing space 12 will not escape to the outside of the washing box 1. At the same time, it can also keep the washing space 12 warm, so that the temperature inside the washing space 12 is always kept at a high temperature, thereby improving the drying effect on the tableware.

[0033] It is worth noting that the airflow channel 23 can converge the airflow. On the one hand, all the air driven by the fan 21 enters the airflow channel 23. The airflow channel 23 can reduce the flow cross-sectional area, increase the airflow speed, and under the guidance of the airflow channel 23, enter the main air passage 141 and branch air passage 142 through the air inlet 151, and then enter the cleaning space 12 through the vent 143. On the other hand, by setting the heating element 22 in the airflow channel 23, all the air driven by the fan 21 can pass through the heating element 22 and be heated by the heating element 22, which greatly increases the temperature of the air entering the cleaning box 1.

[0034] like Figure 6As shown, for ease of assembly, a mounting plate 15 is provided below the support plate 11. The mounting plate 15 is fastened to the support plate 11 to form a flow passage 14 between the mounting plate 15 and the support plate 11. The function switching component 2 is provided on the side of the mounting plate 15 away from the support plate 11, and the air inlet 151 is opened on the mounting plate 15 to communicate with the guide channel 23.

[0035] like Figure 2 and Figure 4 As shown, preferably, the flow channel 23 includes an air inlet section 231, a heating section 232, and a connecting section 233. The fan 21 is connected to the air inlet section 231, the heating element 22 is disposed within the heating section 232, and the connecting section 233 is connected to the air inlet 151. The cross-sectional areas of both the air inlet section 231 and the connecting section 233 are smaller than the cross-sectional area of ​​the heating section 232. That is, along the air flow direction, the cross-sectional area of ​​the flow channel 23 first increases and then decreases. This structure allows a larger heating element 22 to be installed within the flow channel 23, thereby increasing the temperature of the heated air and ensuring that the tableware is dried with sufficiently high-temperature air, thus improving drying efficiency.

[0036] In this embodiment, the bottom surface of the guide channel 23 gradually decreases along the direction close to the air inlet 151. When the user puts the tableware into the washing space 12, water droplets on the tableware will drip onto the support plate 11 and may enter the air passage 14 through the vent 143 and flow into the guide channel 23 through the air inlet 151. The inclined bottom surface can cause the water entering the guide channel 23 to gather at the end away from the fan 21, avoiding water contact with the fan 21 and causing the fan 21 to short-circuit and be damaged.

[0037] Understandably, to prevent excessive water accumulation in the flow channel 23, a drain hole is provided at one end of the flow channel 23 near the air inlet 151, and the drain hole is detachably sealed. When there is a lot of water in the flow channel 23, the user can remove the seal to drain the water and then replace the seal.

[0038] Understandably, the further away from the air inlet 151, the lower the air velocity. This results in a smaller amount of air entering the cleaning space 12 from the branch duct 142, which is farther from the air inlet 151, causing uneven airflow distribution within the cleaning space 12. To solve this problem, the diameter of the vent holes 143 in the branch duct 142, which is farther from the air inlet 151, is larger than the diameter of the vent holes 143 in the branch duct 142, which is closer to the air inlet 151.

[0039] This structure ensures that the resistance to air entering the cleaning space 12 through the vent 143 in the branch duct 142 away from the air inlet 151 is less than the resistance to air entering the cleaning space 12 through the vent 143 in the branch duct 142 near the air inlet 151. As a result, only a small portion of the air near the air inlet 151 can enter the cleaning space 12, thereby increasing the gas pressure in the branch duct 142 away from the air inlet 151 and increasing the air intake through the vent 143 in the branch duct 142 away from the air inlet 151, making the airflow or bubble distribution in the cleaning space 12 more uniform.

[0040] Understandably, when air enters the main air duct 141 from the air inlet 151, it flows along the extension direction of the main air duct 141. If the air were to enter the branch air duct 142 at this time, its flow velocity would be significantly reduced, thus affecting the air intake of the cleaning space 12. For example... Figure 5 and Figure 6 As shown, to solve this problem, the branch airway 142 is inclined in a direction away from the main airway 141 and away from the air inlet 151. That is, the angle between the airflow direction in the branch airway 142 and the main airway 141 is an acute angle, so that the loss of airflow velocity when air enters the branch airway 142 from the main airway 141 is less, thereby increasing the gas pressure in the branch airway 142, so as to increase the airflow velocity entering the cleaning space 12 through the vent 143 and increase the intake volume.

[0041] It is understandable that the air entering the cleaning space 12 will cause the air pressure inside the cleaning space 12 to increase, thereby hindering the entry of subsequent air into the cleaning space 12. Expelling the gas from the cleaning space 12 to the outside of the cleaning chamber 1 will result in heat loss and increase energy consumption. For example... Figure 4 and Figure 7 As shown, to solve the above problems, the upper cover 3 includes a cover body 31 and a partition 32. A return air chamber 33 is provided between the partition 32 and the cover body 31. The partition 32 has a return air hole 321. The function switching component 2 is set in the installation space 13. The return air chamber 33 is connected to the installation space 13.

[0042] Air within the installation space 13 is driven by fan 21 into the guide channel 23, then into the main air duct 141 and branch air duct 142, and finally into the cleaning space 12 through vent 143. The air in the cleaning space 12 is warmer and less dense, causing it to rise and enter the return air chamber 33 through the return air vent 321, before returning to the installation space 13, forming an airflow circulation. This circulation avoids excessive air pressure in the cleaning space 12, which could affect subsequent air intake. Furthermore, when the heating element 22 of the function switching component 2 is activated, the warmer air from the cleaning space 12 returns to the installation space 13 and is driven by fan 21 to pass through the heating element 22 for heating. This significantly reduces the electrical energy required to heat the air, thus achieving energy savings and reducing energy consumption.

[0043] like Figure 3 , Figure 5 and Figure 7 As shown, the top plate 16 has a first connecting hole 161 that communicates with the installation space 13, and the partition 32 has a second connecting hole 322. When the top cover 3 is fastened to the cleaning tank 1, the first connecting hole 161 and the second connecting hole 322 are connected. That is to say, there is no need to set up a pipeline to connect the top cover 3 and the cleaning tank 1. Instead, when the top cover 3 is fastened to the cleaning tank 1, the connection between the first connecting hole 161 and the second connecting hole 322 is used to ensure the smooth flow of circulating air, thereby avoiding the restriction on the top cover 3. This allows the top cover 3 to be completely detached from the cleaning tank 1 when it is opened, making it convenient for users to take and put away tableware, and also facilitating the cleaning and maintenance of the top cover 3 and the cleaning tank 1.

[0044] like Figure 4 and Figure 5 As shown, the side wall of the cleaning chamber 1 is further provided with an air passage 17, which connects the first connecting hole 161 and the installation space 13. Since the installation space 13 is located at the bottom of the cleaning chamber 1 and the first connecting hole 161 is located at the top of the cleaning chamber 1, the air passage 17 on the side wall of the cleaning chamber 1 can connect the first connecting hole 161 and the installation space 13, facilitating the formation of a circulating air path.

[0045] like Figure 3 , Figure 4 , Figures 7-9 As shown, in this embodiment, the automatic cleaning device also includes a spray assembly 5 and a circulation assembly 4. The spray assembly 5 is rotatably mounted on the upper cover 3 and located within the cleaning space 12. The circulation assembly 4 includes a water pump 41 and a connecting pipe 42. The water pump 41 is located below the support plate 11 and connected to the drain hole 19. The connecting pipe 42 connects the water pump 41 and the spray assembly 5.

[0046] The spray assembly 5 sprays pressurized cleaning water onto the surface of the object being cleaned, utilizing the impact force of the water flow and the chemical action of the detergent to remove stains. As the spray assembly 5 rotates and sprays water into the cleaning space 12, the water in the cleaning space 12 is pumped from the cleaning space 12 into the connecting pipe 42 through the drain hole 19 by the water pump 41, and then reaches the spray assembly 5 through the connecting pipe 42, achieving water circulation, reducing water consumption, and achieving water conservation.

[0047] In addition, if the object to be treated is leafy vegetables that can float in water, the air bubbles attached to the bottom of the leafy vegetables will generate an upward lifting force on the leafy vegetables. Combined with the impact force of the washing water flow of the spray component 5, it helps the leafy vegetables to turn over, making it easier for the washing water flow to impact all parts of the surface of the object to be treated, thereby further improving the cleaning effect.

[0048] However, when the cleaning space 12 contains chunks of food such as potatoes or tableware waiting to be processed, if the water level in the cleaning space 12 is higher than the items to be processed, the spray water from the spray component 5 will first impact and dissipate into the upper water layer. Its kinetic energy will be greatly buffered and absorbed by the water layer, making it difficult for the water to directly impact the surface of the items to be processed. As a result, the stains on the surface of the items to be processed are difficult to be cleaned, affecting the cleaning effect.

[0049] To solve the above problems, the automatic cleaning device also includes a water level sensor, which is installed in the cleaning space 12. When the water level in the cleaning space 12 reaches the water level sensor, the cleaning tank 1 stops filling with water, and the water level sensor controls the water level to be lower than the highest point of the object to be treated.

[0050] Once the water level sensor detects that the water level is reached, it can stop the water from entering the cleaning tank 1, thereby ensuring that the water level is lower than the highest point of the object to be treated, allowing the object to be treated to be partially exposed above the water surface. The spray water flow from the spray assembly 5 can directly impact the surface of the object to be treated, avoiding the kinetic energy of the spray water flow being significantly buffered and absorbed by the water layer, thereby cleaning the stains on the surface of the object to be treated and improving the cleaning effect.

[0051] Specifically, the water level sensor can be a float structure, in which the float rises to close the water inlet channel when the water level rises to a preset height; the water level sensor can also be an electronic structure, in which the electronic water level sensor controls the solenoid valve of the water inlet channel to close when the water level rises to a preset height, so as to stabilize the water level at a height that does not exceed the height of the object to be treated.

[0052] In some embodiments, a drive motor is provided inside the upper cover 3 to drive the spray assembly 5 to rotate, so that the water flow can cover the object to be treated from multiple angles and in all directions. However, the spray assembly 5 needs to spray a large amount of water, and the rotating structure makes it difficult to ensure the reliability of the seal. The drive motor and its related electrical connection parts are prone to liquid seepage, which can lead to short circuits in the motor windings, deterioration of insulation performance, or corrosion failure of electrical components. In addition, the installation of the drive motor increases power consumption and structural complexity, thus increasing costs.

[0053] like Figures 7-9 As shown, to solve the above problems, the spray assembly 5 includes a rotating shaft 51 and a spray arm 52. A water supply connector 34 is provided inside the upper cover 3. The water supply connector 34 is connected to the connecting pipe 42. The rotating shaft 51 is rotatably connected to the water supply connector 34. The spray arm 52 is connected to the rotating shaft 51. A water supply channel 53 is provided on the inner wall of the spray arm 52. The water supply channel 53 is connected to the water supply connector 34 through the rotating shaft 51. A drive spray hole 521 connected to the water supply channel 53 is opened on the bottom surface of the spray arm 52. In the circumferential direction of the rotation of the spray arm 52, the spray direction of the drive spray hole 521 is tilted backward in the downward direction so that the reaction force of the spray water flow of the drive spray hole 521 drives the spray arm 52 and the rotating shaft 51 to rotate.

[0054] The water pump 41 pumps water from the cleaning space 12 into the water supply connector 34 through the connecting pipe 42, thereby allowing water to enter the water supply channel 53 of the spray arm 52. The water supply channel 53 inside the spray arm 52 is connected to the drive spray hole 521, allowing water in the water supply channel 53 to be sprayed out through the drive spray hole 521. In the circumferential direction of the rotation of the spray arm 52, along the downward direction, the spray direction of the drive spray hole 521 is tilted backward. Therefore, the reaction force of the sprayed water on the spray arm 52 has two components: vertical and horizontal. The vertical component is canceled out by the spray arm 52 and the rotating shaft 51, while the horizontal component will drive the spray arm 52 and the rotating shaft 51 to rotate. Through the rotation of the spray arm 52, it can be ensured that the water flow can cover the object to be treated from multiple angles and in all directions.

[0055] The spray assembly 5 uses the reaction force of the water flow to drive the spray arm 52 to rotate, thereby eliminating the need for a drive motor. This effectively avoids situations where the electrical structure and related electrical connection parts are short-circuited, the insulation performance deteriorates, or the electrical components corrode and fail due to liquid seepage. It also simplifies the structure, saves power consumption, and reduces costs.

[0056] For ease of description, this embodiment will be illustrated using an example where the rotating shaft 51 is vertically positioned and the spray arm 52 primarily sprays downwards. Wherein, as Figure 8 and Figure 9As shown, in the circumferential direction of the rotation of the spray arm 52, the spray direction of the drive spray hole 521 is tilted backward in a downward direction. This backward tilt is only relative to the rotation direction of the spray arm 52. In practice, the tilt of the drive spray hole 521 is prioritized, and then the spray arm 52 begins to rotate under the reaction force of the water flow sprayed from the drive spray hole 521. Furthermore, the main function of the drive spray hole 521 is to drive the rotation of the spray arm 52, while also cleaning the side walls of the cleaning space 12 and the materials to be treated within the cleaning space 12.

[0057] In this embodiment, the connecting line between the axis of the driving spray hole 521 and the axis of the rotating shaft 51 is the radius of rotation. For ease of description, the driving direction is the horizontal direction that passes through the center of the driving spray hole 521 and is perpendicular to the radius of rotation. That is, the driving direction is the tangent direction of the circular trajectory of the driving spray hole 521 when the spray arm 52 rotates.

[0058] It is worth noting that since the main function of the driving spray hole 521 is to drive the rotation of the spray arm 52, the closer the spray direction of the driving spray hole 521 is to the horizontal plane, the better. This results in the water flow sprayed through the driving spray hole 521 being difficult to directly clean the objects to be treated in the cleaning space 12. To solve the above problem, multiple cleaning spray holes 522 are also provided on the bottom surface of the spray arm 52, and all the cleaning spray holes 522 are connected to the water supply channel 53. The spray direction of the cleaning spray holes 522 is generally downward, and there can be a certain tilt angle, but the tilt angle is smaller than that of the driving spray hole 521, so as to ensure that the water flow sprayed through the cleaning spray hole 522 can directly impact the objects to be treated, so that the water flow has sufficient cleaning force and ensures the cleaning effect.

[0059] like Figure 8 and Figure 9 As shown, in this embodiment, multiple cleaning spray holes 522 are located inside the drive spray hole 521. This structure allows the drive spray hole 521 to be as far away from the axis of the rotating shaft 51 as possible, thereby increasing the lever arm of the reaction force of the water flow sprayed from the drive spray hole 521 on the spray arm 52 and increasing the rotational speed of the spray arm 52.

[0060] In this embodiment, the spraying directions of the multiple cleaning spray holes 522 are not exactly the same. That is, the spraying direction of some cleaning spray holes 522 is vertically downward, and the spraying direction of some cleaning spray holes 522 is at an angle to the vertical direction, so as to make the direction of the spray water flow of the cleaning spray holes 522 more complex, so that the spray water flow can impact the object to be treated at different angles, thereby further improving the cleaning ability and cleaning effect.

[0061] In this embodiment, the spray assembly 5 includes at least two spray arms 52, and both spray arms 52 are connected to the rotating shaft 51. Each spray arm 52 is provided with a drive spray hole 521 and multiple cleaning spray holes 522. The drive spray holes 521 of the multiple spray arms 52 can provide driving force for the rotation of the spray assembly 5 and ensure the balance of driving force. The multiple spray arms 52 can improve the coverage of the spray water flow through the multiple cleaning spray holes 522, ensuring that part of the surface of the object to be treated is completely covered by the spray water flow, thus ensuring the cleaning effect.

[0062] Furthermore, the distances between the multiple cleaning spray holes 522 on at least two spray arms 52 and the axis of the rotating shaft 51 are all different. As the spray assembly 5 rotates, the spray trajectory of each cleaning spray hole 522 and the drive spray hole 521 is a concentric circle, and any two concentric circles do not overlap. That is to say, each cleaning spray hole 522 and the drive spray hole 521 has its own independent cleaning range, avoiding the waste of cleaning capacity due to overlapping cleaning ranges.

[0063] like Figure 3 , Figure 4 and Figure 7 As shown, the connecting pipe 42 includes a first sub-segment 421 and a second sub-segment 422. The upper cover 3 is provided with a first water connection port 323. The first sub-segment 421 is disposed inside the upper cover 3 and connects the first water connection port 323 and the spray assembly 5. The cleaning tank 1 is provided with a second water connection port 18. The second sub-segment 422 is disposed inside the cleaning tank 1 and connects the second water connection port 18 and the water pump 41. When the upper cover 3 is fastened to the cleaning tank 1, the first water connection port 323 and the second water connection port 18 are connected.

[0064] It is understandable that the top cover 3 and the cleaning tank 1 are detachably connected. The first sub-section 421 and the second sub-section 422 are connected by the first water connection port 323 and the second water connection port 18, so that the top cover 3 and the cleaning tank 1 do not need a complete water pipe to connect their water paths. This avoids restricting the top cover 3, allowing the top cover 3 to be completely detached from the cleaning tank 1 when opened, which is convenient for users to put and take out the items to be processed, and also facilitates the cleaning and maintenance of the top cover 3 and the cleaning tank 1.

[0065] It is worth noting that the second segment 422 of the connecting pipe 42 is located inside the gas passage 17, and the second water passage connection port 18 is opened on the top plate 16.

[0066] like Figure 3 and Figure 7As shown, in this embodiment, one of the first water connection port 323 and the second water connection port 18 is provided with a connector 324, which can be plugged into the other of the first water connection port 323 and the second water connection port 18. By plugging and mating the connector with one of the first water connection ports 323 and the second water connection port 18, it is not only convenient for the user to align the first water connection port 323 and the second water connection port 18, but also avoids water leakage caused by a loose connection between the first water connection port 323 and the second water connection port 18.
