Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to a fruit and vegetable cleaning device, a control method thereof and an integrated sink. BACKGROUND

[0002] The sink type fruit and vegetable cleaning machine is a kitchen appliance for cleaning fruits and vegetables, and is widely used due to its convenience. Patent application No. CN213524902U discloses a fruit and vegetable cleaning machine, which includes a sink, a fruit and vegetable basket assembly and a motor. The fruit and vegetable basket assembly includes a basket body and an impeller. The basket body is installed in the sink, and a containing cavity is formed in the basket body. The motor and the impeller are located outside the containing cavity, and the motor is detachably connected with the impeller for driving the impeller to rotate. During use, the motor drives the impeller to rotate, and in turn drives the water in the sink to swirl and flow to clean the fruits and vegetables. Under normal circumstances, the entire cleaning process of the fruit and vegetable cleaning machine includes two or even more cleaning stages. Each cleaning stage includes the actions of water injection, cleaning assembly stirring and cleaning, and water drainage.

[0003] During the operation of the fruit and vegetable cleaning device, the mud and sand on the food materials will be washed off during the stirring and cleaning action. Most of the mud and sand will deposit at the bottom of the sink. During the stirring and cleaning action of the cleaning assembly, the mud and sand at the bottom of the sink may float up again and adhere to the food materials under the disturbance of the water flow. During the water drainage action, if the amount of mud and sand in the sink is large, a part of the mud and sand will be difficult to drain with the water and will remain at the bottom of the sink. If there is a next cleaning stage, the mud and sand may adhere to the food materials again, affecting the cleaning efficiency. If there is no next cleaning stage, not only will the cleaning effect of the food materials be poor, but the user will also need to further clean the sink, resulting in a poor user experience.

[0004] Therefore, there is an urgent need for a fruit and vegetable cleaning device, a control method thereof and an integrated sink to solve the above technical problems. SUMMARY

[0039] The present application has the following advantages:

[0040] The fruit and vegetable cleaning device of the present application comprises:

[0041] (1) The fruit and vegetable cleaning device comprises a first water tank, a cleaning assembly, a guide plate, a deposition tank assembly and a flushing assembly. The guide plate is arranged at the first drainage port of the first water tank. The deposition tank is communicated with the sidewall of the first drainage tank through the drainage gap between the guide plate and the sidewall. The drainage assembly is used to drain water in the deposition tank. The flushing assembly is used to flush water into the deposition tank. When the fruit and vegetable cleaning device is used, the food is placed in the first water tank, and water is added to the first water tank. The cleaning assembly disturbs the water in the first water tank, so as to clean the food in the first water tank. The mud and sand generated during the cleaning process will sink to the bottom. Most of the mud and sand will enter the deposition tank from the drainage gap between the guide plate and the sidewall of the first drainage port, thereby realizing the isolation of the mud and sand and the food. Under the blocking action of the guide plate and the gravity of the mud and sand, the mud and sand is not easy to return to the first water tank. On the one hand, the physical isolation of the mud and sand and the food is realized during the stirring and cleaning process, thereby effectively preventing the mud and sand from adhering to the food again during stirring and cleaning. On the other hand, since most of the mud and sand enters the deposition tank, only a small amount of mud and sand will be left at the bottom of the first water tank. This part of mud and sand can be taken away when the first water tank is drained. That is, there is no situation that the mud and sand cleaned in the previous cleaning stage remains in the first water tank or that there is mud and sand remaining in the first water tank after the cleaning is completely finished. Not only is the cleaning effect of the food directly improved, but the user also does not need to further clean the first water tank after the food cleaning is finished, and the user experience is good.

[0042] (2) The amount of mud and sand in the deposition tank is detected by the mud and sand amount detection assembly, and the drainage assembly and the flushing assembly can be opened and closed based on the detection result of the mud and sand amount detection assembly. Therefore, when the mud and sand amount detection assembly detects that the amount of mud and sand in the deposition tank is greater than or equal to a first preset value, the drainage assembly and the flushing assembly are opened to flush the mud and sand in the deposition tank in time. On the one hand, it can avoid the situation that the amount of mud and sand in the deposition tank is too large to return to the first water tank from the deposition tank. On the other hand, it can realize the drainage of the mud and sand in the deposition tank while the cleaning assembly is cleaning, thereby improving the overall cleaning efficiency and the final cleaning effect. On the other hand, it can also avoid the situation that the mud and sand in the deposition tank is too much to affect the smoothness of the drainage of the first water tank.

[0043] The integrated sink can separate the silt from the food materials during cleaning, and automatically clean the silt, so that the cleaning effect on the food materials and the use experience of the user are improved.

[0044] The control method of the fruit and vegetable cleaning device can open the flushing assembly and the drainage assembly to flush the silt in the deposition tank during the cleaning action of the cleaning assembly, so that the silt in the deposition tank is prevented from returning to the first sink, the cleaning assembly can clean while the silt in the deposition tank is discharged, the overall cleaning efficiency and the final cleaning effect are improved, and the smoothness of the drainage of the first sink is improved.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0070] The present embodiment provides a fruit and vegetable cleaning device, and the following orientation descriptions such as upper, lower, front, rear, left and right are relative to the user when the fruit and vegetable cleaning device is in normal use. Specifically, as shown in Figure 1 and Figure 2 The fruit and vegetable cleaning device includes a first water tank 10, a cleaning assembly 20, a water injection assembly 40, a drainage assembly 60 and a control module. The first water tank 10 is used to accommodate food materials to be cleaned. The first water tank 10 is provided with a water injection port 12 and a first drainage port 13, the water injection assembly 40 is connected at the water injection port 12 for realizing water injection into the first water tank 10. The drainage assembly 60 is connected at the first drainage port 13 for draining water in the first water tank 10. The cleaning assembly 20 is at least partially arranged in the first water tank 10 for disturbing water in the first water tank 10, so that the water in the first water tank 10 forms a vortex to drive the food materials for cleaning. In the present embodiment, the cleaning assembly 20, the water injection assembly 40 and the drainage assembly 60 are in communication connection with the control module, the control module controls the cleaning assembly 20, the water injection assembly 40 and the drainage assembly 60 to act respectively when executing a pre-stored cleaning program, thereby realizing the whole cleaning process of the fruit and vegetable cleaning device. It can be understood that in some embodiments, in addition to the water injection assembly 40 which can inject water into the first water tank 10, a faucet or the like can also be arranged on one side of the first water tank 10 for injecting water into the first water tank 10.

[0071] In the present embodiment, as shown in Figure 1As shown, the first water tank 10 is configured as an open-top tank structure, so as to facilitate the taking and placing of food materials. In some embodiments, the fruit and vegetable cleaning device further comprises a cover plate (not shown in the figure), which can be covered on the opening of the water tank. When the fruit and vegetable cleaning device is cleaning food materials, covering the cover plate on the water tank can prevent water or food materials from splashing. Optionally, the first water tank 10 can be made of stainless steel, ceramic or other materials. As shown in the figure, Figure 2 As shown, the water inlet 12 is arranged on the side wall of the first water tank 10. The water injection assembly 40 comprises a first water inlet pipe 42 and a first water inlet electromagnetic valve 41. One end of the first water inlet pipe 42 is in communication with a water source, and the other end is in communication with the water inlet 12. The first water inlet electromagnetic valve 41 is arranged on the first water inlet pipe 42, and the first water inlet electromagnetic valve 41 is in communication connection with the control module. The control module controls the first water inlet electromagnetic valve 41 to start or stop water injection through the water inlet 12. The first water outlet 13 is arranged on the bottom plate of the first water tank 10, so as to facilitate the complete drainage of water in the first water tank 10. The drainage assembly 60 comprises a first drainage pipe 61 and a first drainage electromagnetic valve 62. One end of the first drainage pipe 61 is in communication with the first water outlet 13, and the other end is used to communicate with a sewer or a sewage collection structure. The first drainage electromagnetic valve 62 is installed on the first drainage pipe 61, and the first drainage electromagnetic valve 62 is electrically connected with the control module. The control module controls the first drainage electromagnetic valve 62 to start or stop water drainage through the first water tank 10. In this embodiment, the control module comprises an operation panel 90 arranged on one side of the first water tank 10, which is used for the user to select the cleaning mode. In some embodiments, the cleaning mode of the fruit and vegetable cleaning device comprises leafy vegetable mode, root and stem mode, berry mode and the like. The cleaning assembly 20 has different cleaning intensity in different cleaning modes, so as to ensure that the food materials are cleaned thoroughly, and avoid damage to the food materials in the cleaning process.

[0072] In the related art, the fruit and vegetable cleaning device, the stirring and cleaning action can wash the mud and sand on the food materials down. Most of the mud and sand will be deposited at the bottom of the water tank. When the cleaning assembly 20 stirs and cleans, the mud and sand at the bottom of the water tank may also float up and re-adhere to the food materials under the disturbance of the water flow. When the drainage action is performed, if the amount of mud and sand in the water tank is large, a part of the mud and sand will be difficult to drain with water and will be retained at the bottom of the water tank. If there is a next cleaning stage, the mud and sand may re-adhere to the food materials, affecting the cleaning efficiency. If there is no next cleaning stage, not only will it directly lead to poor cleaning effect of the food materials, but the user also needs to further clean the water tank, resulting in poor user experience.

[0073] To this end, as shown in the figure, Figure 2As shown, the fruit and vegetable cleaning device further comprises a flow guide plate 51, a sediment tank 72, a drainage assembly 60 and a flushing assembly 71, wherein the flow guide plate 51 is arranged at the first drainage port 13 and forms a drainage gap 15 between the flow guide plate 51 and the side wall of the first drainage port 13, and the sediment tank 72 is arranged at the lower side of the first water tank 10 and communicates with the first water tank 10 through the drainage gap 15; the drainage assembly 60 is connected with the sediment tank 72 and used for draining water in the first water tank 10 and the sediment tank 72; the flushing assembly 71 is connected with the sediment tank 72 and used for flushing water into the sediment tank 72, and the flushing of the sediment tank 72 can be realized by simultaneously opening the drainage assembly 60 and the flushing assembly 71.

[0074] In use of the fruit and vegetable cleaning device, the food materials are placed in the first water tank 10, water is injected into the first water tank 10, and the cleaning assembly 20 disturbs the water in the first water tank 10, so as to clean the food materials in the first water tank 10. The mud and sand generated in the cleaning process will sink to the bottom, and most of the mud and sand will enter the sediment tank 72 from the drainage gap 15 between the flow guide plate 51 and the side wall of the first drainage port 13, so as to realize the isolation of the mud and sand and the food materials. Under the blocking action of the flow guide plate 51 and the gravity of the mud and sand, the mud and sand are not easy to return to the first water tank 10. On the one hand, the physical isolation of the mud and sand and the food materials is realized during the action of stirring and cleaning, so as to effectively prevent the mud and sand from re-adhering to the food materials during stirring and cleaning. On the other hand, since most of the mud and sand enters the sediment tank 72, only a small amount of mud and sand will be left at the bottom of the first water tank 10, and this part of mud and sand can be taken away when the first water tank 10 is drained. That is to say, the mud and sand cleaned in the previous cleaning stage will not remain in the first water tank 10, or the mud and sand will not remain in the first water tank 10 after the cleaning is completely finished. Not only the cleaning effect of the food materials is directly improved, but also the user does not need to further clean the first water tank 10 after the cleaning of the food materials is completed, and the user experience is good.

[0075] In the embodiment, as shown in Figure 2As shown, the sediment tank 72 is roughly configured as a funnel structure with a large upper end cross section and a small lower end cross section, so as to facilitate the sediment entering the sediment tank 72 to gather at the bottom of the sediment tank 72. Optionally, the flow guide plate 51 can be fixed on the side wall of the sediment tank 72 through a connecting piece. Optionally, the shape of the flow guide plate 51 is substantially consistent with the shape of the first drain port 13, so that the drain gap 15 forms a gap with uniform width at different circumferential positions, so that the sediment at each position can smoothly enter the sediment tank 72 from the drain gap 15. The first drain pipe 61 is in communication with the sediment tank 72. The position where the first drain pipe 61 is connected with the sediment tank 72 is located at the lower end of the sediment tank 72, so as to be able to drain all the water or sediment in the sediment tank 72. The flushing assembly 71 includes a second water inlet pipe 711 and a second water inlet electromagnetic valve 712. One end of the second water inlet pipe 711 is in communication with a water source, and the other end is in communication with the sediment tank 72. The second water inlet electromagnetic valve 712 is arranged on the second water inlet pipe 711 and is used to open and close the second water inlet pipe 711. The second water inlet electromagnetic valve 712 is in communication connection with the control module, that is, the control module can automatically control the opening and closing of the second water inlet electromagnetic valve 712. The connection position of the second water inlet pipe 711 and the sediment tank 72 is located at the lower end of the sediment tank 72, so as to be able to flush all the sediment in the sediment tank 72 out.

[0076] As shown in Figure 2 , the cleaning assembly 20 includes a motor 21 and an impeller 22, wherein the motor 21 is arranged outside the first water tank 10, and the impeller 22 is arranged in the first water tank 10. The motor 21 and the impeller 22 are drivingly connected through an output shaft 23. When the motor 21 outputs rotation, the impeller 22 is driven to rotate, so as to disturb the water flow to achieve cleaning of the food materials. It can be understood that when the motor 21 outputs different rotation speeds, the impeller 22 has different rotation speeds, and the cleaning assembly 20 has different cleaning intensities.

[0077] As shown in Figure 2 , the impeller 22 is arranged on the upper side of the flow guide plate 51. In this way, when the impeller 22 rotates, the water flow speed around the impeller 22 is smaller than the water flow speed near the side wall of the first water tank 10, so that the sediment is more easily pushed by the water flow to the surrounding of the impeller 22, and then enters the sediment tank 72 from the drain gap 15, so as to realize the separation of the sediment and the food materials in the first water tank 10. Specifically, the output shaft 23 is sequentially arranged through the side wall of the sediment tank 72 and the flow guide plate 51 and connected with the impeller 22, so as to ensure that the impeller 22 is located on the upper side of the flow guide plate 51. The output shaft 23 can be rotationally matched with the flow guide plate 51 through a bearing or the like structure.

[0078] The fruit and vegetable cleaning device further comprises a silt amount detection assembly (not shown in the figure) for detecting the amount of silt in the sediment tank 72, which is in communication connection with the control module, and then indirectly realizes communication connection with the drainage assembly 60 and the flushing assembly 71, respectively, so that the drainage assembly 60 and the flushing assembly 71 can be opened or closed based on the detection result of the silt amount detection assembly. Specifically, when the silt amount detection assembly detects that the amount of silt in the sediment tank 72 is greater than or equal to the first preset value, both the drainage assembly 60 and the flushing assembly 71 are opened, that is, the drainage assembly 60 flushes water into the sediment tank 72 to timely flush the silt in the sediment tank 72 away through the drainage assembly 60. On the one hand, the situation that the silt in the sediment tank 72 returns to the first sink 10 can be avoided due to excessive amount of silt in the sediment tank 72; on the other hand, the silt deposited in the sediment tank 72 can be discharged while the cleaning assembly 20 is cleaning, thereby improving the overall cleaning efficiency and the final cleaning effect; on the other hand, the smoothness of the drainage of the first sink 10 can also be ensured due to the excessive accumulation of silt in the sediment tank 72.

[0079] Optionally, in the present embodiment, the silt amount detection assembly can be a turbidity detection assembly, which can detect the turbidity of the water in the sediment tank 72. After the turbidity detection assembly detects the turbidity of the water in the sediment tank 72, it sends the detection result to the control module. The control module converts the turbidity into a silt amount value and compares it with the first preset value to determine whether the sediment tank 72 needs to be flushed. In some embodiments, the silt amount detection assembly can also be a visual detection assembly, which can obtain an image of the sediment tank 72 and send it to the control module. The control module analyzes the color of the image and / or the number of particulate matters in the image, converts the result into a silt amount value, and compares it with the first preset value to determine whether the sediment tank 72 needs to be flushed.

[0080] It can be understood that during the flushing of the sediment tank 72, the silt amount detection assembly can detect the amount of silt in the sediment tank 72 in real time. When the detected silt amount value is less than or equal to the second preset value, the control module controls the drainage assembly 60 and the flushing assembly 71 to be closed, thereby stopping the flushing of the sediment tank 72. The second preset value is a value less than the first preset value.

[0081] During the stirring and cleaning of the cleaning assembly 20, the actual water amount in the first sink 10 can fluctuate after the flushing and drainage of the sediment tank 72 by opening the flushing assembly 71 and the drainage assembly 60.

[0082] To this end, the fruit and vegetable cleaning device of the present embodiment further comprises a first flow detection member and a second flow detection member. The first flow detection member is configured to detect the water flushing flow of the flushing assembly 71. The second flow detection member is configured to detect the water draining flow of the draining assembly 60 during the water flushing of the flushing assembly 71. The first flow detection member and the second flow detection member are in communication connection with the control module, thereby indirectly achieving communication connection with the water injection assembly 40. The water injection assembly 40 can inject water into the first sink 10 based on the detection results of the first flow detection member and the second flow detection member. Specifically, when the water flushing flow detected by the first flow detection member is less than the water draining flow detected by the second flow detection member, it indicates that the water amount in the first sink 10 is reduced. At this time, the control module can control the water injection assembly 40 to inject water into the first sink 10, thereby ensuring the stability of the water amount in the first sink 10 and further ensuring good cleaning effect. Alternatively, the amount of water supplemented by the water injection assembly 40 into the first sink 10 can be the difference between the water draining flow and the water flushing flow. Without departing from the inventive concept of the present application, the first flow detection member and the second flow detection member can be any one of the prior art, which is not limited herein.

[0083] In some embodiments, the flushing assembly 71 and the draining assembly 60 can be turned on before the water injection action of at least one cleaning stage of the fruit and vegetable cleaning device, so as to flush the sediment tank 72. For example, the cleaning program executed by the fruit and vegetable cleaning device includes n cleaning stages. The flushing assembly 71 and the draining assembly 60 are turned on before the water injection action of the 2nd to nth cleaning stage, that is, the sediment tank 72 is drained clean before water injection, thereby avoiding the mud in the sediment tank 72 floating into the first sink 10 during water injection and affecting the cleaning effect of the food materials. Alternatively, the flushing of the sediment tank 72 before water injection can be set to stop after a certain time or a certain amount of water flushing.

[0084] During the stirring and cleaning of the food materials by the cleaning assembly 20, floating materials are also cleaned out. The floating materials are difficult to be completely drained, thereby remaining on the food materials and finally leading to poor cleaning effect.

[0085] To this end, as shown in Figure 1 the side wall of the first sink 10 is provided with a floating material discharge outlet 11. The floating material discharge outlet 11 is arranged at the upper end of the side wall of the first sink 10. The floating material discharge outlet 11 is configured to discharge the floating materials in the first sink 10 before the draining of the first sink 10, thereby avoiding the floating materials re-adhering to the food materials during the draining of the first sink 10 and improving the cleaning effect of the fruit and vegetable cleaning device on the food materials.

[0086] In some embodiments, as shown in Figure 1 and Figure 3As shown, the position of the floating material outlet 11 is higher than the maximum liquid level of the fruit and vegetable cleaning device during the cleaning operation. The water injection assembly 40 is configured to inject water into the first water tank 10 at a preset timing to make the liquid level in the first water tank 10 reach the floating material outlet 11. After the cleaning operation of each cleaning stage is performed for a certain period of time or after the cleaning operation is completed, the upper layer of water in the first water tank 10 will accumulate floating materials. At this time, the water injection assembly 40 injects water into the first water tank 10, so that the liquid level in the first water tank 10 reaches the height of the floating material outlet 11. Under the driving of continuous water injection, the floating materials are discharged from the floating material outlet 11 to the outside of the first water tank 10. Therefore, when the water in the first water tank 10 is subsequently discharged, the floating materials will not adhere to the food materials, thereby improving the cleaning effect.

[0087] In some embodiments, the preset timing is after the cleaning assembly 20 completes the cleaning operation and before the water drainage assembly 60 performs the water drainage operation. At this time, the food materials will sink downward under the action of gravity after losing the disturbance of the impeller 22, and the floating materials will still float on the water surface. At this time, the water injection assembly 40 injects water into the first water tank 10, which can ensure that the floating materials are discharged from the floating material outlet 11 and can also avoid the food materials from being discharged from the floating material outlet 11 as much as possible, thereby reducing unnecessary loss of food materials. In some embodiments, the preset timing can also be after the cleaning assembly 20 starts to perform the cleaning operation for a certain period of time.

[0088] As shown in FIG. 1, Figure 1 and Figure 3 The floating material outlet 11 is configured as a long strip hole extending in the horizontal direction. Such a configuration can make it easier for the floating materials to be discharged from the floating material outlet 11. In the present embodiment, the floating material outlet 11 is provided as one and is formed in the side wall of one side of the first water tank 10. Alternatively, the floating material outlet 11 and the water injection port 12 are respectively located in the opposite side walls of the first water tank 10. In this way, during the process in which the water injection assembly 40 injects water into the first water tank 10 through the water injection port 12, the floating materials will flow to the side wall opposite to the water injection port 12 under the action of the water flow, and then enter the floating material outlet 11 more easily, so as to better separate the floating materials.

[0089] As shown in FIG. 1, Figure 3 The fruit and vegetable cleaning device further includes an overflow tank 31, which is in communication with the first water tank 10 through the floating material outlet 11. The floating materials discharged from the floating material outlet 11 will enter the overflow tank 31. In the present embodiment, the lower end of the overflow tank 31 is provided with a second water drainage port 311, and the second water drainage port 311 is connected with a second water drainage pipe 33. It can be understood that when the floating materials enter the overflow tank 31 from the floating material outlet 11, water will also enter the overflow tank 31 synchronously, and the second water drainage pipe 33 can drain the water in the overflow tank 31, thereby reducing the volume of the overflow tank 31 and making the structure of the entire fruit and vegetable cleaning device more compact.

[0090] As shown in Figure 3 , the fruit and vegetable cleaning device further comprises a filter 32, the filter 32 is arranged in the overflow tank 31, and the water in the floating material discharge port 11 enters the overflow tank 31 and reaches the second water outlet 311 after passing through the filter 32. That is, the floating material can be intercepted by the filter 32, and the water can be discharged from the second water outlet 311. In this way, under the premise of ensuring that the overall structure of the fruit and vegetable cleaning device is compact, the accumulation of floating material can be avoided to cause the second drain pipe 33 to be blocked, and the maintenance cost of the fruit and vegetable cleaning device during use is reduced. In some embodiments, the overflow tank 31 shares part of the side wall with the first water tank 10, at this time, the floating material discharge port 11 directly penetrates the side wall shared by the two to realize the communication between the overflow tank 31 and the first water tank 10. In some embodiments, the overflow tank 31 and the first water tank 10 do not share the side wall, and the side wall of the overflow tank 31 is provided with a through hole, the through hole is opposite to the floating material discharge port 11 and is communicated through a pipe. In this embodiment, the overflow tank 31 is arranged at the front side of the first water tank 10, so as to facilitate the user to handle the floating material in the filter 32. The overflow tank 31 is in a funnel structure, and the second drain pipe 33 is installed at the bottom of the overflow tank 31.

[0091] As shown in Figure 3 , in this embodiment, the top of the overflow tank 31 is provided with a first sink 318. The filter 32 comprises a filter basket 323 and a hanging ear 321, the filter basket 323 is inserted into the overflow tank 31, and the hanging ear 321 is lapped on the first sink 318. In this way, the installation of the filter 32 can be realized, and the structure is simple and convenient to disassemble and assemble. In this embodiment, the filter 32 is further provided with a hand holding part 322, the hand holding part 322 is connected to the top of the filter basket 323, which is used for the user to hold, so as to facilitate the taking and placing of the filter 32, and improve the convenience of using the fruit and vegetable cleaning device. As shown in Figure 3 , the top of the first water tank 10 is provided with a second sink 14, and the second sink 14 is flush with the first sink 318. In this way, when the water in the first water tank 10 is too much, it can be discharged into the overflow tank 31 through the second sink 14 and the first sink 318, and finally discharged from the second water outlet 311, avoiding the overflow of water in the first water tank 10.

[0092] In some embodiments, as shown in Figure 2As shown, the overflow tank 31 is provided with a water immersion sensor 35, which is in communication connection with the water injection assembly 40. The water injection assembly 40 can continue to inject water into the first water tank 10 for a first time period after the water immersion sensor 35 detects water. When the water immersion sensor 35 detects water in the overflow tank 31, it indicates that water and floating objects have entered the overflow tank 31 from the floating object drain. Continuing to inject water into the first water tank 10 for the first time period can ensure that the floating objects in the first water tank 10 are basically drained into the overflow tank 31. Optionally, the first time period can be 5s, 10s, 15s, etc., which is not limited herein. It can be understood that the first time period can also be set to different values for different cleaning modes. Optionally, the water immersion sensor 35 is arranged at a position where the second drain 311 is connected to the second drain pipe 33.

[0093] In some embodiments, the overflow tank 31 is provided with a water immersion sensor 35, which is in communication connection with the water injection assembly 40. The water injection assembly 40 can continue to inject a preset amount of water into the first water tank 10 after the water immersion sensor 35 detects water. When the water immersion sensor 35 detects water in the overflow tank 31, it indicates that water and floating objects have entered the overflow tank 31 from the floating object drain. Continuing to inject the preset amount of water into the first water tank 10 after this moment can ensure that the floating objects in the first water tank 10 are basically drained into the overflow tank 31. Optionally, the preset amount of water can be 1L, 2L, 3L, etc., which is not limited herein. It can be understood that the preset amount of water can also be set to different values for different cleaning modes. Optionally, the water immersion sensor 35 is arranged at a position where the second drain 311 is connected to the second drain pipe 33.

[0094] As shown, the overflow tank 31 is provided with a water immersion sensor 35, which is in communication connection with the water injection assembly 40. The water injection assembly 40 can continue to inject water into the first water tank 10 for a first time period after the water immersion sensor 35 detects water. When the water immersion sensor 35 detects water in the overflow tank 31, it indicates that water and floating objects have entered the overflow tank 31 from the floating object drain. Continuing to inject water into the first water tank 10 for the first time period can ensure that the floating objects in the first water tank 10 are basically drained into the overflow tank 31. Optionally, the first time period can be 5s, 10s, 15s, etc., which is not limited herein. It can be understood that the first time period can also be set to different values for different cleaning modes. Optionally, the water immersion sensor 35 is arranged at a position where the second drain 311 is connected to the second drain pipe 33. Figure 1 As shown, the overflow tank 31 is provided with a water immersion sensor 35, which is in communication connection with the water injection assembly 40. The water injection assembly 40 can continue to inject water into the first water tank 10 for a first time period after the water immersion sensor 35 detects water. When the water immersion sensor 35 detects water in the overflow tank 31, it indicates that water and floating objects have entered the overflow tank 31 from the floating object drain. Continuing to inject water into the first water tank 10 for the first time period can ensure that the floating objects in the first water tank 10 are basically drained into the overflow tank 31. Optionally, the first time period can be 5s, 10s, 15s, etc., which is not limited herein. It can be understood that the first time period can also be set to different values for different cleaning modes. Optionally, the water immersion sensor 35 is arranged at a position where the second drain 311 is connected to the second drain pipe 33.

[0095] Figures 4-6 ​As shown, the fruit and vegetable cleaning device includes an overflow tank 31 and a filter screen plate 52. The overflow tank 31 is arranged at one side of the first water tank 10 and is in communication with the first water tank 10 through the floating material discharge outlet 11. The filter screen plate 52 is arranged between the overflow tank 31 and the first water tank 10 and is used for returning water in the overflow tank 31 to the first water tank 10.

[0096] When the fruit and vegetable cleaning device performs a cleaning action, the generated floating material can enter the overflow tank 31 from the floating material discharge outlet 11 under the action of the disturbed water flow, and the water entering the overflow tank 31 together with the floating material is returned to the first water tank 10 through the filter screen plate 52. On the one hand, the floating material is blocked and retained in the overflow tank 31, which realizes the isolation of the food materials in the first water tank 10, thereby avoiding the floating material from re-adhering to the food materials during the cleaning process and the subsequent discharge of water in the first water tank 10, and further improving the cleaning effect of the fruit and vegetable cleaning device. On the other hand, the water overflowing from the floating material discharge outlet 11 is returned to the first water tank 10 through the filter screen plate 52, which has the effect of saving water on the basis of ensuring the stability of the water amount in the first water tank 10 during the cleaning process.

[0097] In this embodiment, a connecting wall 312 is arranged between the overflow tank 31 and the first water tank 10, the floating material discharge outlet 11 penetrates the connecting wall 312 to communicate the overflow tank 31 and the first water tank 10, and a through hole 313 is further arranged on the connecting wall 312 to penetrate the connecting wall 312 to communicate the overflow tank 31 and the first water tank 10. The filter screen plate 52 is used for covering the through hole 313 and is detachably connected with the overflow tank 31 or the first water tank 10. By arranging the filter screen plate 52 to be detachably connected with the overflow tank 31 or the first water tank 10, the filter screen plate 52 can be easily detached and cleaned, thereby improving the convenience of cleaning the fruit and vegetable cleaning device itself. In this embodiment, the connecting wall 312 is a wall plate connecting the side wall of the first water tank 10 and the side wall of the overflow tank 31. In some embodiments, the connecting wall 312 can also be a side wall shared by the first water tank 10 and the second water tank 81.

[0098] As Figure 5 and Figure 6As shown, the inner wall of the overflow groove 31 or the inner wall of the first water tank 10 is provided with a plug assembly 314 around the through hole 313, and the plug assembly 314 is arranged to form a plug groove 315, and the filter screen plate 52 is inserted into the plug groove 315. The plug-in and plug-out of the filter screen plate 52 is convenient to operate, and does not need to be achieved by means of other fasteners, and the structure is also simpler. In the embodiment, the plug assembly 314 is arranged on the inner wall of the overflow groove 31. In this way, the filter screen plate 52 is located in the overflow groove 31, which not only does not occupy the space of the first water tank 10, but also ensures the smoothness of the inner wall of the first water tank 10, thereby avoiding scratching the food materials in the first water tank 10. Of course, in other embodiments, the plug assembly 314 can also be arranged on the inner wall of the first water tank 10. In the embodiment, the plug assembly 314 is configured as a U-shaped structure with an L-shaped cross section, so as to form the plug groove 315 after being fixed on the inner wall of the overflow groove 31 or the inner wall of the first water tank 10. Alternatively, the opening of the U-shaped plug assembly 314 is arranged upward, so that the filter screen plate 52 can be inserted and removed from the top and bottom directions, which can further improve the convenience of user operation. Of course, in some embodiments, the opening of the U-shaped plug assembly 314 can also be arranged to the side under the condition that the space permits, so that the filter screen plate 52 is inserted along the horizontal direction.

[0099] As shown, Figure 4 The floating material discharge port 11 and the filter screen plate 52 are arranged 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 rotating speed along the circumference of the impeller 22 (i.e., the horizontal direction). In the embodiment, the floating material discharge port 11 and the filter screen plate 52 are arranged along the circumference of the impeller 22, so that the water flow has a movement trend along the horizontal direction after entering the first water tank 10 from the floating material discharge port 11. Under this trend, the water flow can more smoothly flow back to the first water tank 10 from the filter screen plate 52, so that the circulation of the water flow between the first water tank 10 and the overflow groove 31 is smoother, thereby more effectively filtering out the floating materials and improving the cleaning effect of the fruit and vegetable cleaning device. In the embodiment, the floating material discharge port 11 is configured as an elongated hole extending along the horizontal direction, and is arranged at one side of the upper end of the filter screen plate 52. By configuring the floating material discharge port 11 as an elongated hole extending along the horizontal direction and arranging it at the position of the upper end of the filter screen plate 52, the floating material discharge port 11 in the overflow groove 31 can be effectively inhibited from returning to the first water tank 10 during the cleaning process.

[0100] As shown, Figure 4As shown, the bottom plate of the overflow tank 31 comprises an inclined portion 316, which extends downwardly in the direction from the floating material discharge outlet 11 to the filter screen plate 52. In this way, the volume of the overflow tank 31 corresponding to the floating material discharge outlet 11 is smaller than the volume corresponding to the filter screen plate 52, so that the water and floating material entering the overflow tank 31 from the floating material discharge outlet 11 will flow more smoothly to the filter screen plate 52 under the action of the volume difference, i.e., the water flow entering the overflow tank 31 from the floating material discharge outlet 11 will return to the first water tank 10 from the filter screen plate 52, ensuring the smoothness of the water circulation and relieving the floating material in the overflow tank 31 from returning to the first water tank 10 from the floating material discharge outlet 11, thereby improving the filtering effect on the floating material.

[0101] In the embodiment, as shown in Figure 6 The bottom of the overflow tank 31 is provided with a second water discharge opening 311, and the second water discharge opening 311 is connected with a second water discharge pipe 33. The second water discharge pipe 33 is provided with a second water discharge electromagnetic valve 34 for opening and closing the second water discharge pipe 33. Before the water injection assembly 40 starts to inject water into the first water tank 10, the first water discharge electromagnetic valve 62 and the second water discharge electromagnetic valve 34 are both closed, so as to avoid water from being discharged from the first water discharge pipe 61 or the second water discharge pipe 33 during the water injection and cleaning processes. When the water in the first water tank 10 needs to be discharged after completing a stage of cleaning, the first water discharge electromagnetic valve 62 and the second water discharge electromagnetic valve 34 are both opened, at which time part of the water in the first water tank 10 is discharged from the first water discharge opening 13, and part of the water is discharged from the second water discharge opening 311. The water discharged from the second water discharge opening 311 also automatically discharges the floating material in the overflow tank 31, so as to avoid the influence of the floating material on the next stage of cleaning and improve the overall cleaning effect. In the embodiment, as shown in Figure 4 The bottom plate of the overflow tank 31 further comprises a horizontal portion 317 connected to the lower end of the inclined portion 316. The second water discharge opening 311 is arranged on the horizontal portion 317.

[0102] As shown in Figure 4 The embodiment further provides another integrated water tank, which comprises a second water tank 81 and the fruit and vegetable cleaning device. The second water tank 81 is connected with the first water tank 10. The integrated water tank can improve the cleaning effect on the food materials by using the fruit and vegetable cleaning device. The second water tank 81 can be used for washing tableware or manually cleaning food materials, and has high flexibility.

[0103] The embodiment further provides a control method of the fruit and vegetable cleaning device, which is executed by using any one of the fruit and vegetable cleaning devices. Specifically, the control method of the fruit and vegetable cleaning device comprises the following steps.

[0104] During the cleaning operation of the cleaning assembly 20, a preset signal is obtained, and the flushing assembly 71 and the drainage assembly 60 are turned on to flush the sediment tank 72.

[0105] The control method of the fruit and vegetable cleaning device can flush the sediment in the sediment tank 72 by turning on the flushing assembly 71 and the drainage assembly 60 during the cleaning operation of the cleaning assembly 20. On the one hand, it can avoid the situation that the sediment in the sediment tank 72 returns to the first water tank 10 due to excessive amount of sediment in the sediment tank 72. On the other hand, it can realize the discharge of the sediment in the sediment tank 72 while the cleaning assembly 20 is cleaning, thereby improving the overall cleaning efficiency and the final cleaning effect. On the other hand, it can also avoid the influence of excessive accumulation of sediment in the sediment tank 72 on the smoothness of the drainage of the first water tank 10.

[0106] In this embodiment, the preset signal for triggering the flushing of the sediment tank 72 is that the amount of sediment in the sediment tank 72 is greater than or equal to a first preset value. Specifically, as shown in Figure 7 after the cleaning assembly 20 starts the cleaning operation, the amount of sediment in the sediment tank 72 is obtained in real time. When it is determined that the amount of sediment in the sediment tank 72 is greater than or equal to the first preset value, it means that the amount of sediment in the sediment tank 72 is too large, and the flushing of the sediment tank 72 is started at this time. If it is determined that the amount of sediment in the sediment tank 72 is less than the first preset value, it returns to the step of obtaining the amount of sediment in the sediment tank 72. The specific way of obtaining the amount of sediment in the sediment tank 72 is described above and will not be repeated here.

[0107] In some embodiments, the preset signal for triggering the flushing of the sediment tank 72 can also be that the cleaning assembly 20 starts to execute the cleaning operation for a preset time.

[0108] As shown in Figure 7 after the flushing assembly 71 and the drainage assembly 60 are turned on to flush the sediment tank 72, the amount of sediment in the sediment tank 72 is detected in real time, and it is determined whether the current amount of sediment is less than or equal to a second preset value. If not, it means that the current amount of sediment in the sediment tank 72 is still large, and the step of turning on the flushing assembly 71 and the drainage assembly 60 to flush the sediment tank 72 is returned to, and the flushing of the sediment tank 72 is continued. If yes, it means that the current amount of sediment in the sediment tank 72 is small, and the flushing assembly 71 and the drainage assembly 60 can be turned off to stop the flushing of the sediment tank 72.

[0109] Based on the above-mentioned flushing of the sediment tank 72, which may cause the water level in the first water tank 10 to fluctuate, as shown in Figure 7 the control method of the fruit and vegetable cleaning device further comprises:

[0110] After the flushing assembly 71 and the draining assembly 60 are closed, the water flow of the flushing assembly 71 and the water flow of the draining assembly 60 during the flushing of the sediment tank 72 are obtained; if the water flow of the flushing assembly 71 is less than the water flow of the draining assembly 60, water is added to the first water tank 10, so as to ensure the water amount in the first water tank 10 is stable, and then a good cleaning effect is ensured. The water amount added to the first water tank 10 by the water adding assembly 40 can be the difference between the water flow of the draining assembly 60 and the water flow of the flushing assembly 71. In some embodiments, if the water flow of the flushing assembly 71 is greater than the water flow of the draining assembly 60, a certain amount of water can be drained by opening the draining assembly 60, so as to ensure the water amount in the first water tank 10 is stable. The specific amount of water drained is the difference between the water flow of the flushing assembly 71 and the water flow of the draining assembly 60.

[0111] Obviously, the above embodiments of the present application are merely exemplary for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, according to the idea of the present application, the specific embodiments and application scope can be changed, and the content of the present specification should not be understood as limiting the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the claims of the present application.
