It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] This embodiment provides a fruit and vegetable washing device. The following descriptions of directions such as up, down, front, back, left, and right refer to the device's position relative to the user during normal use. Specifically, as shown... Figure 1 and Figure 2 As shown, the fruit and vegetable cleaning device includes a first water tank 10, a cleaning component 20, a water injection component 40, a drainage component 60, and a control module. The first water tank 10 is used to hold the food to be cleaned. The first water tank 10 is provided with a water inlet 12 and a first drain outlet 13. The water injection component 40 is connected to the water inlet 12 for injecting water into the first water tank 10. The drainage component 60 is connected to the first drain outlet 13 for draining the water from the first water tank 10. The cleaning component 20 is at least partially disposed within the first water tank 10, used to agitate the water in the first water tank 10, thereby creating a vortex to clean the food. In this embodiment, the cleaning component 20, the water injection component 40, and the drainage component 60 are all communicatively connected to the control module. When executing a pre-stored cleaning program, the control module controls the operation of the cleaning component 20, the water injection component 40, and the drainage component 60 respectively, thus realizing the entire cleaning process of the fruit and vegetable cleaning device. It is understood that in some embodiments, in addition to the water injection component 40 injecting water into the first water tank 10, a faucet or the like can also be installed on one side of the first water tank 10 for injecting water into the first water tank 10.

[0047] In this embodiment, as Figure 1As shown, the first water tank 10 is constructed with an open top, facilitating the loading and unloading of food. In some embodiments, the fruit and vegetable washing device also includes a cover (not shown), which can be placed over the open end of the water tank. Placing the cover over the water tank when washing food prevents water or food from splashing. Optionally, the first water tank 10 can be made of materials such as stainless steel or ceramic. Figure 2 As shown, the water inlet 12 is located on the side wall of the first water tank 10. The water injection assembly 40 includes a first water inlet pipe 42 and a water inlet solenoid valve 41. One end of the first water inlet pipe 42 is connected to a water source, and the other end is connected to the water inlet 12. The water inlet solenoid valve 41 is mounted on the first water inlet pipe 42 and is communicatively connected to the control module. The control module controls the water inlet 12 to start or stop water injection by controlling the opening and closing of the water inlet solenoid valve 41. The first drain outlet 13 is located on the bottom plate of the first water tank 10, thereby facilitating the complete drainage of water from the first water tank 10. The drainage assembly 60 includes a first drain pipe 61 and a first solenoid valve 62. One end of the first drain pipe 61 is connected to the first drain outlet 13, and the other end is used to connect to a sewer or sewage collection structure. The first solenoid valve 62 is mounted on the first drain pipe 61 and is electrically connected to the control module. The control module controls the opening and closing of the first drain pipe 61 by controlling the opening and closing of the first solenoid valve 62. In this embodiment, the control module includes an operation panel 90, which is located on one side of the first water tank 10 and is used for the user to select the washing mode. In some embodiments, the washing modes of the fruit and vegetable washing device include leafy vegetable mode, root vegetable mode, berry mode, etc. In different washing modes, the washing component 20 has different washing intensity, thereby ensuring that the food is cleaned and avoiding damage to the food during the washing process.

[0048] like Figure 2 As shown, the cleaning assembly 20 includes a motor 21 and an impeller 22, wherein the motor 21 is disposed outside the first water tank 10, and the impeller 22 is disposed inside the first water tank 10. The motor 21 and the impeller 22 are connected by a transmission shaft 23. When the motor 21 rotates, it drives the impeller 22 to rotate, thereby agitating the water flow to clean the food. It can be understood that when the motor 21 outputs different speeds, the impeller 22 rotates at different speeds, corresponding to different cleaning forces of the cleaning assembly 20.

[0049] During the cleaning process, the cleaning component 20 will wash out floating objects. These floating objects are difficult to drain smoothly when the first water tank 10 drains water, and thus re-adhere to the food, resulting in poor cleaning effect.

[0050] In this regard, such as Figures 1-3As shown, the first water tank 10 of this embodiment is provided with a floating object outlet 11 on its side wall. The fruit and vegetable washing device also includes an overflow trough 31 and a filter plate 50. The overflow trough 31 is located on one side of the first water tank 10 and is connected to the first water tank 10 through the floating object outlet 11. The filter plate 50 is located between the first water tank 10 and the overflow trough 31. The filter plate 50 is configured to allow water in the overflow trough 31 to flow back into the first water tank 10.

[0051] When the fruit and vegetable washing device cleans food, the washing component 20 agitates the water in the first water tank 10, thereby cleaning the food in the first water tank 10. Floating debris generated during the washing process, under the influence of the agitated water flow, can enter the overflow tank 31 from the floating debris outlet 11. The water that enters the overflow tank 31 along with the floating debris flows back into the first water tank 10 through the filter screen 50. On the one hand, the floating debris is blocked and retained in the overflow tank 31, achieving isolation from the food in the first water tank 10, thus preventing the floating debris from re-adhering to the food during the washing process and when the water is subsequently discharged from the first water tank 10, thereby improving the cleaning effect of the fruit and vegetable washing device. On the other hand, the water overflowing from the floating debris outlet 11 flows back into the first water tank 10 through the filter screen 50, ensuring a stable water volume in the first water tank 10 during the washing process and also achieving a water-saving effect.

[0052] In this embodiment, as Figure 1 As shown, the overflow trough 31 is located on the front side of the first water tank 10, which facilitates the user in handling floating objects inside the filter element. In other embodiments, the overflow trough 31 may also be located on the left, right, or rear side of the first water tank 10, and no specific limitation is made here.

[0053] like Figures 2-4 As shown, a connecting wall 312 is provided between the overflow trough 31 and the first water tank 10. The floating debris outlet 11 passes through the connecting wall 312 to connect the overflow trough 31 and the first water tank 10. A through hole 313 is also provided on the connecting wall 312, which also connects the overflow trough 31 and the first water tank 10. A filter screen plate 50 is used to cover the through hole 313 and is detachably connected to the overflow trough 31 or the first water tank 10. By setting the filter screen plate 50 to be detachably connected to the overflow trough 31 or the first water tank 10, it is easy to remove the filter screen plate 50 for cleaning, thereby improving the convenience of cleaning the fruit and vegetable cleaning device itself. In this embodiment, the connecting wall 312 is a wall plate that connects the side wall of the first water tank 10 and the side wall of the overflow trough 31. In some embodiments, the connecting wall 312 may also be a side wall shared by the first water tank 10 and the second water tank 81.

[0054] like Figure 2 and Figure 3As shown, an insert plate assembly 314 is provided around the through hole 313 on the inner wall of the overflow trough 31 or the inner wall of the first water tank 10. The insert plate assembly 314 forms a slot 315, into which the filter plate 50 is inserted. The detachable method of inserting and removing the filter plate 50 is convenient and does not require other fasteners, making the structure simpler. In this embodiment, the insert plate assembly 314 is provided on the inner wall of the overflow trough 31. With this arrangement, the filter plate 50 is located inside the overflow trough 31, which not only does not occupy the space of the first water tank 10, but also ensures that the inner wall of the first water tank 10 is smooth, thereby avoiding scratching the food in the first water tank 10. Of course, in other embodiments, the insert plate assembly 314 can also be provided on the inner wall of the first water tank 10. In this embodiment, the insert plate assembly 314 is constructed as a U-shaped structure with an L-shaped cross-section, so that after it is fixed to the inner wall of the overflow trough 31 or the inner wall of the first water tank 10, it forms a slot 315. Optionally, the opening of the U-shaped insert assembly 314 is arranged facing upwards, so that the filter plate 50 can be inserted and removed from the top and bottom, which can further improve the convenience of user operation. Of course, in some embodiments, if space permits, the opening of the U-shaped insert assembly 314 can also be arranged to the side, so that the filter plate 50 can be inserted laterally.

[0055] like Figure 4 As shown, the floating debris outlet 11 and the filter plate 50 are arranged sequentially along the circumference of the impeller 22. When the impeller 22 drives the water in the first water tank 10 to rotate, the water generates a rotational speed along the circumference (i.e., horizontal direction) of the impeller 22. In this embodiment, by arranging the floating debris outlet 11 and the filter plate 50 along the circumference of the impeller 22, the water flow, after entering the first water tank 10 from the floating debris outlet 11, has a horizontal movement tendency. Under this tendency, the water flow can more smoothly flow back from the filter plate 50 to the first water tank 10, improving the smoothness of the water flow circulation between the first water tank 10 and the overflow tank 31, thereby more effectively filtering out floating debris and improving the cleaning effect of the fruit and vegetable washing device. In this embodiment, the floating debris outlet 11 is constructed as an elongated hole extending horizontally and is located on one side of the upper end of the filter plate 50. By constructing the floating debris outlet 11 as an elongated hole extending in the horizontal direction and positioning it at the upper end of the filter plate 50, the floating debris outlet 11 in the overflow tank 31 can be effectively prevented from returning to the first water tank 10 during the cleaning process.

[0056] like Figure 1As shown, the bottom plate of the overflow tank 31 includes an inclined portion 316 extending downwards along the direction from the floating debris outlet 11 towards the filter screen plate 50. This arrangement ensures that the volume of the overflow tank 31 at the floating debris outlet 11 is smaller than the volume at the filter screen plate 50. Therefore, after floating debris and water enter the overflow tank 31 from the floating debris outlet 11, they will flow more smoothly towards the filter screen plate 50 due to the aforementioned volume difference. This guides the water flowing from the floating debris outlet 11 into the overflow tank 31 to return from the filter screen plate 50 to the first water tank 10, ensuring smooth water circulation and mitigating the return of floating debris from the floating debris outlet 11 to the first water tank 10, thus improving the filtration effect on floating debris.

[0057] In this embodiment, as Figure 1 and Figure 5 As shown, a second drain outlet 311 is provided at the bottom of the overflow tank 31. A second drain pipe 33 is connected to the second drain outlet 311, and a second solenoid valve 32 is provided on the second drain pipe 33. The second solenoid valve 32 is used to open and close the second drain pipe 33. Before the water injection assembly 40 starts to inject water into the first water tank 10, both the first solenoid valve 62 and the second solenoid valve 32 are closed, thereby preventing water from being discharged from the first drain pipe 61 or the second drain pipe 33 during the water injection and cleaning process. When a stage of cleaning is completed and it is necessary to drain the water in the first water tank 10, both the first solenoid valve 62 and the second solenoid valve 32 are opened. At this time, part of the water in the first water tank 10 is discharged from the first drain outlet 13, and part of the water is discharged from the second drain outlet 311. The water discharged through the second drain outlet 311 also automatically discharges the floating objects in the overflow tank 31, thereby preventing the floating objects from affecting the next stage of cleaning and improving the overall cleaning effect. In this embodiment, the bottom plate of the overflow tank 31 also includes a horizontal part 317, which is connected to the lower end of the inclined part 316. The second drain outlet 311 is located on the horizontal part 317.

[0058] In this embodiment, as Figure 5 As shown, the second drain pipe 33 is connected to the first drain pipe 61, and the connection point is located upstream of the first solenoid valve 62. With this configuration, even if the second solenoid valve 32 is open when the first solenoid valve 62 is not open, the water in the overflow tank 31 will not be discharged through the first discharge pipe. In some embodiments (not shown), the connection point between the second drain pipe 33 and the first drain pipe 61 is located downstream of the second solenoid valve 32. Based on this, the second solenoid valve 32 can be set to open preferentially over the first solenoid valve 62, thereby allowing the water in the first water tank 10 to be discharged preferentially from the second drain outlet 311, thus more thoroughly flushing the floating debris in the overflow tank 31 and better removing the floating debris from the overflow tank 31.

[0059] like Figure 2 and Figure 5As shown, the fruit and vegetable washing device also includes a sedimentation tank 63 and a guide plate 70. The guide plate 70 is installed at the first drain outlet 13 and forms a drainage gap 15 between it and the side wall of the first drain outlet 13. The sedimentation tank 63 is installed below the first water tank 10 and is connected to the first water tank 10 through the drainage gap 15. The first drain pipe 61 is connected to the lower end of the sedimentation tank 63. When the washing component 20 performs the washing action, the mud and sand washed off the food will enter the sedimentation tank 63 through the drainage gap 15, thereby achieving separation of mud and sand from the food. Under the blocking effect of the guide plate 70 and the gravity of the mud and sand themselves, the mud and sand are not easy to return to the first water tank 10. That is to say, the physical isolation between mud and sand and food is achieved before the water in the first water tank 10 is drained. Therefore, during the drainage process, the mud and sand will not re-attach to the food, thereby improving the washing effect of the fruit and vegetable washing device on the food. In this embodiment, the impeller 22 is set on the upper side of the guide plate 70. With this configuration, when the impeller 22 rotates, the water flow velocity around the impeller 22 is lower than the water flow velocity near the side wall of the first water tank 10. Therefore, sediment is more easily pushed by the water flow to the vicinity of the impeller 22, and then enters the sedimentation tank 63 through the drainage gap 15, achieving sediment separation. Furthermore, the washing process of a fruit and vegetable washing device typically includes two or more washing stages, each stage including water injection, washing, and drainage. If the sediment in the sedimentation tank 63 is not completely drained during the previous washing stage, the guide plate 70 can also block the water in the sedimentation tank 63, preventing sediment from returning to the first water tank 10. Specifically, as... Figure 2 As shown, the output shaft 23 passes through the side wall of the sedimentation tank 63 and the guide plate 70 in sequence and is connected to the impeller 22, thereby ensuring that the impeller 22 is located on the upper side of the guide plate 70.

[0060] like Figure 1 As shown, this embodiment also provides an integrated sink, which includes a second sink 81 and the aforementioned fruit and vegetable washing device. The second sink 81 is connected to the first sink 10. By employing the aforementioned fruit and vegetable washing device, the integrated sink can improve the cleaning effect on food. The second sink 81 can be used for washing tableware or for manually washing food, offering high flexibility. Optionally, the first sink 10 and the second sink 81 can be integrally formed. Optionally, the second sink 81 is located to the left or right of the first sink 10. In this embodiment, a faucet 82 is also provided at the second sink 81 for injecting water into the second sink 81. Figure 1 As shown, a third drain outlet 811 is also provided at the bottom of the second water tank 81. The third drain outlet 811 is used to drain the water in the second water tank 81.
