Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a vegetable cleaning station with automatic water changing function. Background Technology

[0002] As people's living standards continue to improve, their demands for food safety and hygiene are also increasing. Vegetables, as an indispensable part of daily diet, are directly related to food safety and health through proper cleaning. Traditional vegetable cleaning methods mainly rely on manual operation or simple rinsing devices, which are not only labor-intensive and inefficient, but also difficult to thoroughly remove contaminants such as dirt and pesticide residues from the surface of vegetables.

[0003] In recent years, some vegetable cleaning equipment with automated functions has gradually appeared on the market, such as cleaning stations with functions such as spraying and circulating water systems. However, most existing cleaning equipment still has obvious defects: serious waste of water resources is one of the most prominent problems. Most cleaning equipment adopts a one-time rinsing mode, and the water after cleaning is discharged directly without treatment, resulting in a large waste of clean water resources. Especially in large restaurants, supermarkets, and agricultural product processing plants, this one-time water use mode consumes a huge amount of water every day.

[0004] Therefore, there is a particular need for a vegetable washing station with automatic water exchange function that can purify water quality in order to solve the above problems. Utility Model Content

[0022] Example: A vegetable washing station with automatic water changing function, such as... Figures 1-6 As shown, the system includes a support component 1, a water tank 2, support feet 3, a cleaning pool 4, a filter frame 5, a nozzle 10, a first water pump 11, a connecting pipe 1001, a water level sensor 12, a turbidity sensor 13, a drain pipe 14, a first solenoid valve 15, a second solenoid valve 1501, a filter 18, a second delivery pipe 19, a third water pump 1901, a fan unit 20, a control panel 21, a lifting mechanism, and a sterilization mechanism. The water tank 2 is located on the right side wall of the support component 1. Symmetrical support feet 3 are bolted to the bottom left of the support component 1 and the bottom right of the water tank 2. The support feet 3 are placed on a level surface and have anti-slip sleeves at their bottoms to enhance stability. A cleaning tank 4 is provided on the top of the support 1 and the top of the water tank 2. A water outlet is provided on the bottom surface of the cleaning tank 4, and a removable filter frame 5 is installed inside the water outlet. A nozzle 10 is provided on the rear side of the top of the cleaning tank 4, and a first water pump 11 is provided at the bottom of the nozzle 10. The water pipe on the nozzle 10 is connected to the water outlet pipe on the first water pump 11, and the water inlet pipe on the first water pump 11 is connected to the connecting pipe 1001. A water level sensor 12 is provided inside the cleaning tank 4. A turbidity sensor 13 is provided on the bottom surface inside the left side of the cleaning tank 4. A drain pipe 14 is connected to the left side water outlet, and a first solenoid valve 15 is provided on the drain pipe 14 to control the flow of water in the drain pipe 14. A second solenoid valve 1501 is connected to the bottom water outlet of the right side of the cleaning tank 4 via a pipe to control the flow of water in the right side water outlet. A filter 18 is connected to the bottom of the right-side washing tank 4. Both the filter 18 and the second solenoid valve 1501 are located inside the water tank 2. A second delivery pipe 19 connects the filter 18 to the left-side washing tank 4, and the second delivery pipe 19 is connected to a third water pump 1901. A blower unit 20 is installed on the top of both washing tanks 4 to dry the surface moisture of the washed vegetables. A control panel 21 is installed on the front wall of the left-side washing tank 4. The first water pump 11, water level sensor 12, turbidity sensor 13, first solenoid valve 15, second solenoid valve 1501, filter 18, third water pump 1901, blower unit 20, and control panel 21 are electrically connected to a controller. A lifting mechanism is installed inside the washing tank 4, and a sterilization mechanism is installed inside the water tank 2.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the lifting mechanism includes a motor 6, a threaded rod 7, a guide rod 8, and a filter frame 9. The motor 6 is fixedly connected inside the cleaning tank 4 and is electrically connected to the controller. The left motor 6 is located inside the support 1, and the right motor 6 is located inside the water tank 2. The output shaft of the motor 6 is connected to the threaded rod 7, which is vertically set and rotatably connected to the cleaning tank 4. The guide rod 8 is set on the right side of the bottom of the left cleaning tank 4 and the left side of the bottom of the right cleaning tank 4. The threaded rod 7 is threadedly connected to the edge of the filter frame 9, and the filter frame 9 is slidably connected to the guide rod 8. The forward and reverse rotation of the motor 6 drives the threaded rod 7 to rotate forward and reverse, thereby realizing the automatic lifting and lowering of the filter frame 9.

[0024] like Figures 2-4 As shown, the sterilization mechanism includes an ultraviolet water purifier 16, a first delivery pipe 17, and a second water pump 1701. The ultraviolet water purifier 16 is bolted to the bottom left side of the right cleaning pool 4. The ultraviolet water purifier 16 is electrically connected to the controller. The ultraviolet water purifier 16 is located inside the water tank 2. The first delivery pipe 17 connects the water tank 2 and the left cleaning pool 4. The first delivery pipe 17 is connected to the second water pump 1701. The second water pump 1701 is connected to an outlet pipe that extends into the left cleaning pool 4. The second water pump 1701 is electrically connected to the controller and is used to deliver water from the left cleaning pool 4 to the water tank 2.

[0025] First, place the vegetables to be washed into the left filter frame 9, and connect the connecting pipe 1001 to the external water source to prepare for the first water pump 11 to supply water. Then, start the first water pump 11 on the left through the control panel 21. Clean water enters the first water pump 11 on the left through the left connecting pipe 1001, and is then delivered to the left spray nozzle 10 through the outlet pipe on the first water pump 11. The left spray nozzle 10 sprays high-pressure water onto the vegetables in the left filter frame 9 for preliminary rinsing to remove surface dirt and impurities. During the washing process, the left water level sensor 12 monitors the water level in the left washing tank 4 in real time. If the water level is too high, a signal is sent to the controller, and the controller automatically shuts off the left first water pump 11. At the same time, the turbidity sensor 13 continuously monitors the impurity content in the water. After washing, the wastewater flows to the bottom of the washing tank 4. Large impurities in the wastewater are intercepted by the filter frame 5 on the left side to prevent blockage of the drain pipe 14. If the turbidity of the water exceeds the set threshold, the control panel 21 opens the first solenoid valve 15, and the wastewater is discharged through the drain pipe 14. After discharge, the first solenoid valve 15 is closed via the control panel 21. Then, the left motor 6 is started via the control panel 21. The left motor 6 drives the left threaded rod 7 to rotate, causing the left filter frame 9 to rise smoothly and lift off the water surface. Then, the left motor 6 is closed via the control panel 21, and the residual water at the bottom of the left filter frame 9 drips naturally to reduce water accumulation. Then, the vegetables are removed from the left filter frame 9 and placed into the right filter frame 9. The right first water pump 11 is started via the control panel 21. Clean water enters the right first water pump 11 through the right connecting pipe 1001 and is then delivered to the right nozzle 10. The right nozzle 10 sprays high-pressure water onto the vegetables in the right filter frame 9 for a second rinse. The right water level sensor 12 detects the water level in real time. If the water level is too high, it sends a signal to the controller to stop the right first water pump 11. After cleaning, the second solenoid valve 1501 is opened via control panel 21, allowing wastewater to flow into water tank 2. Once the wastewater has completely flowed out, the second solenoid valve 1501 is closed via control panel 21. The ultraviolet water purifier 16 and filter 18 are then activated via control panel 21 to sterilize and purify the wastewater. After purification, the third water pump 1901 is activated via control panel 21. The third water pump 1901 returns the purified water to the left cleaning pool 4 via the second delivery pipe 19, which can be used for the next cleaning, thus achieving water resource recycling. After delivery, the third water pump 1901 is turned off via control panel 21. Next, start the right motor 6 via control panel 21, which drives the right threaded rod 7 to rotate. The right filter frame 9 rises smoothly along the right guide rod 8 and the right washing pool 4, detaching from the water surface for easy removal of vegetables. Then, turn off the right motor 6 via control panel 21. The residual water at the bottom of the right filter frame 9 drips off naturally. Then, start the fan unit 20 via control panel 21 to blow dry air into the filter frame 9 area to accelerate the evaporation of moisture from the vegetable surface. After drying, turn off the fan unit 20 via control panel 21 and remove the cleaned vegetables.If the turbidity sensor 13 detects that the water quality does not exceed the standard, the control panel 21 starts the second water pump 1701 to transport the water in the left washing pool 4 to the water tank 2 through the first conveying pipe 17. After the conveying is completed, the second water pump 1701 is turned off through the control panel 21, and the above sterilization and circulation process is repeated to achieve water-saving cleaning. Finally, the cleaned vegetables are taken away.
