Description

Technical Field

[0001] This utility model belongs to the field of fruit cleaning technology, and specifically relates to a fruit cleaner. Background Technology

[0002] Fruit cleaning typically involves removing dirt or pesticide residues from the fruit surface to meet food safety requirements. Currently, fruit farmers use cleaning machines to perform preliminary cleaning of the fruit before sorting and packaging.

[0003] However, current fruit washers have some shortcomings in practical applications: manual operation increases labor intensity and has low efficiency; the washing force is difficult to control precisely, easily damaging the fruit; the water flow disturbance during washing is limited, preventing the fruit from being fully turned over and creating blind spots; at the same time, water splashes easily out of the washer, making it inconvenient to use. To solve these problems, this patent proposes a high-efficiency solution based on an aeration mechanism design and an adjustable washing mode, aiming to achieve high efficiency, controllability, and good protection for the fruit during the fruit washing process. Utility Model Content

[0004] To overcome the problems of existing fruit washers, such as high labor intensity due to manual operation, difficulty in controlling the washing force, insufficient water flow disturbance leading to blind spots, and easy splashing, this invention provides a fruit washer. This device improves washing efficiency and protects the integrity of the fruit through an aeration mechanism and adjustable washing modes.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A fruit cleaner mainly includes a cleaning tank, a cleaning basket, a cover plate, a water inlet pipe, a water outlet pipe, an aeration mechanism, and a controller. The cleaning tank has a hollow internal structure with a supporting beam welded to the top. The cleaning basket is detachably mounted on the supporting beam. Handles are welded to both sides of the top of the cleaning basket. The cover plate is installed on the top of the cleaning basket. The water inlet pipe is connected to the top side wall of the cleaning tank via a flange, and the water outlet pipe is connected to the bottom side wall of the cleaning tank via a flange. The aeration mechanism includes an air pump, a delivery pipe, a diversion pipe, and an aeration disc. A support platform is welded to the end of the cleaning tank, and the air pump is fixedly mounted on the support platform. One end of the delivery pipe is connected to the air pump, and the other end extends into the cleaning tank and is fixed by a sealing ring. The diversion pipes are installed at equal intervals inside the cleaning tank, and the aeration disc is installed on the diversion pipes, located directly below the cleaning basket. The controller is installed on the side wall of the cleaning tank. The air pump is electrically connected to the controller via a wire. Valves are installed on the inlet and outlet pipes. The valves are manual valves or electrically controlled valves that are electrically connected to the controller via a wire. The controller integrates a timer module and an aeration intensity adjustment module. The timer module is used to set the cleaning time, and the aeration intensity adjustment module is used to adjust the output power of the air pump to control the intensity and density of the bubbles generated. The controller is fixedly equipped with a waterproof cover on top to prevent water from splashing onto the controller and to protect the internal electronic components. The number of cleaning baskets is four, which are respectively attached to the support beam. The surface of the support beam is covered with anti-slip rubber pads to increase the friction between the cleaning baskets and the support beam and prevent the cleaning baskets from sliding. The aeration disc is a microporous aeration disc with an aeration hole diameter of 0.1-0.5mm. The surface of the aeration disc is provided with fine aeration holes, and the gas is released evenly in the form of tiny bubbles through the aeration holes, thereby improving the cleaning effect. The washing basket is made of food-grade stainless steel and has evenly distributed water-permeable holes on its surface. The diameter of the water-permeable holes is 2mm, which can ensure the flow of water when washing fruits and prevent the fruits from coming into contact with harmful substances. Place the fruit to be washed into the washing basket, and use the handle to place the basket on the support beam of the washing tank. The anti-slip rubber pad increases the friction between the basket and the support beam, ensuring stable placement. Then, inject clean water into the washing tank through the inlet pipe until the water level covers the fruit in the basket. Start the air pump, which delivers air through the delivery pipe to the distribution pipe. The air is then distributed to the aeration discs. The microporous structure on the surface of the aeration discs releases the air evenly in the form of tiny bubbles, creating strong bubble agitation. As the bubbles rise, they push the fruit over, providing a gentle impact wash to the fruit's surface, preventing damage from mechanical action. The controller's internal timer module controls the washing duration according to a preset time, and the aeration intensity adjustment module adjusts the air pump's output power as needed, thereby changing the bubble density and intensity to suit the washing requirements of different types of fruit. After washing, open the valve on the outlet pipe to drain the wastewater, and remove the washing basket to complete the washing process. The beneficial effects of this utility model are: This invention utilizes an automatic aeration mechanism to clean fruit without manual intervention, reducing labor intensity. The microbubbles released by the aeration disc apply a gentle impact to the fruit surface, avoiding damage caused by excessive force in traditional cleaning methods. The bubbles generated by the aeration mechanism create strong turbulence in the water, causing the fruit to turn over, eliminating blind spots and ensuring a thorough cleaning. The design of the cleaning basket, combined with the sealed cover, effectively limits water splashing and enhances ease of use. Attached Figure Description

[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0013] This utility model discloses a fruit washer, which mainly includes a washing tank 1, a washing basket 2, a cover plate 3, a water inlet pipe 4, a water outlet pipe 5, an aeration mechanism 6, and a controller 7. The washing tank 1 is the main body of the whole device, and its interior is a hollow structure used to hold washing water and fruit. A supporting beam 8 is welded to the top of the washing tank 1 to ensure stable support for the washing basket 2. The washing basket 2 overlaps the supporting beam 8. The contact surface between the washing basket 2 and the supporting beam 8 is covered with an anti-slip rubber pad. The anti-slip rubber pad is made of rubber material with a high coefficient of friction, which can effectively increase the friction between the washing basket 2 and the supporting beam 8 and prevent the washing basket 2 from shifting or tipping over due to water flow disturbance. There are four washing baskets 2, which are placed at different positions on the supporting beam 8. Users can wash up to four different kinds of fruit at the same time, or flexibly decide the number of baskets to use according to the amount of fruit to be washed. Each washing basket 2 has handles 9 welded to both sides of its top, making it easy for operators to take the washing basket 2 out of the washing tank 1 or put it in.

[0014] like Figure 1-3 As shown, cover plate 3 is installed on top of cleaning basket 2. Cover plate 3 is designed as a flat structure with sealing strips on its edges, which fit tightly against the top opening of cleaning basket 2 to prevent water splashing. Water inlet pipe 4 is installed on the top side wall of cleaning tank 1 via a flange connection. A sealing ring is provided at the flange connection to ensure a tight seal between water inlet pipe 4 and cleaning tank 1. Water outlet pipe 5 is also installed on the bottom side wall of cleaning tank 1 via a flange connection to facilitate complete drainage of wastewater. Both water inlet pipe 4 and water outlet pipe 5 are equipped with valves 15. Valves 15 can be manual or electrically controlled. When an electrically controlled valve is used, valve 15 is electrically connected to controller 7 via a wire, and controller 7 controls its opening or closing.

[0015] like Figure 4 As shown, the aeration mechanism 6 mainly consists of an air pump 10, a delivery pipe 11, a distribution pipe 12, and an aeration disc 13. A support platform 14 is welded to the end of the cleaning tank 1. The surface of the support platform 14 is polished to ensure its flatness and load-bearing capacity. The air pump 10 is mounted on the support platform 14. The outlet end of the air pump 10 is connected to one end of the delivery pipe 11, and the other end of the delivery pipe 11 extends into the cleaning tank 1 and is fixed to the side wall of the cleaning tank 1 by a sealing ring to prevent gas leakage. The distribution pipes 12 are installed at equal intervals inside the cleaning tank 1. The aeration discs 13 are installed on the distribution pipes 12, located directly below the cleaning basket 2. There are multiple aeration discs 13, evenly distributed on the distribution pipes 12, ensuring that gas can be evenly released into the water in the cleaning tank 1. The aeration discs 13 are microporous aeration discs, with fine aeration holes on their surface, the pore size ranging from 0.1 to 0.5 mm. Gas is released through the aeration holes in the form of tiny bubbles, forming strong bubble turbulence.

[0016] like Figure 1 As shown, the controller 7 is installed on the side wall of the cleaning tank 1. A waterproof cover 16 is installed on the top of the controller 7 to protect the internal electronic components from moisture corrosion. The controller 7 integrates a timing module and an aeration intensity adjustment module. The timing module is used to set the cleaning duration. The user can input a preset time through the buttons on the controller 7, and the controller 7 controls the running time of the air pump 10 according to the preset time. The aeration intensity adjustment module is used to adjust the output power of the air pump 10, thereby changing the density and intensity of the bubbles. The user can select the appropriate aeration intensity according to the cleaning needs of different types of fruits. The controller 7 is electrically connected to the air pump 10 through wires. At the same time, when the valve 15 is an electrically controlled valve, the controller 7 is also electrically connected to the valve 15 through wires to realize the automated control of the entire cleaning process.

[0017] The washing basket 2 is made of food-grade stainless steel and has evenly distributed water-permeable holes on its surface. The diameter of the water-permeable holes is 2mm, which can ensure the flow of water during the washing process and prevent the fruit from falling out due to the large hole diameter.

[0018] First, place the fruit to be cleaned into the cleaning basket 2. Use the handle 9 to place the cleaning basket 2 onto the support beam 8 of the cleaning tank 1. Cover the top of the cleaning basket 2 with the cover plate 3, ensuring a tight seal between the cover plate 3 and the sealing strip of the cleaning basket 2 to prevent water splashing. Then, inject clean water into the cleaning tank 1 through the water inlet pipe 4 until the liquid level covers the fruit in the cleaning basket 2. Start the air pump 10. The air pump 10 delivers gas to the distribution pipe 12 through the delivery pipe 11. The gas is then distributed to the aeration disc 13 via the distribution pipe 12. The microporous structure on the surface of the aeration disc 13 allows the gas to be released evenly in the form of tiny bubbles, creating strong bubble turbulence. As the bubbles rise in the water, they push the fruit over, simultaneously applying a gentle impact to the fruit surface, achieving thorough cleaning. The timing module inside the controller 7 controls the cleaning duration according to a preset time, and the aeration intensity adjustment module adjusts the output power of the air pump 10 as needed, thereby changing the density and intensity of the bubbles to adapt to the cleaning needs of different types of fruit. After cleaning is complete, the controller 7 sends a signal to open valve 15 on the outlet pipe 5, discharging the wastewater. When an electrically controlled valve is used, the controller 7 sends a signal via a wire to control valve 15 to open; when a manual valve is used, the operator manually rotates the handle of valve 15 to open it. After the wastewater is discharged through the outlet pipe 5, the operator uses handle 9 to remove the cleaning basket 2 from the cleaning tank 1, completing the entire cleaning process.

[0019] Work process: In actual operation, the user first sets the cleaning duration and aeration intensity using the buttons on the controller 7. For example, for fruits with delicate skin such as strawberries, a lower aeration intensity can be selected to reduce bubble density and impact; while for fruits with harder skin such as apples or oranges, the aeration intensity can be appropriately increased to enhance the cleaning effect. The controller 7 adjusts the output power of the air pump 10 according to preset parameters, thereby changing the density and intensity of the bubbles and achieving precise control of the cleaning process.

[0020] After setting the parameters, evenly place the fruit to be washed into the washing basket 2. To prevent some surfaces from not fully contacting the water flow due to excessive stacking of fruit during the washing process, the fruit load should be controlled to within two-thirds of the capacity of the washing basket 2. Then, use the handle 9 to place the washing basket 2 stably on the support beam 8. The high friction coefficient of the anti-slip rubber pad can effectively prevent the washing basket 2 from shifting or tipping over due to water flow disturbance. After placement, cover the top of the washing basket 2 with the cover plate 3. The sealing strip on the edge of the cover plate 3 fits tightly with the top opening of the washing basket 2, thereby effectively limiting water splashing and improving ease of use. Then, clean water is injected into the washing tank 1 through the water inlet pipe 4 until the liquid level completely covers the fruit in the washing basket 2. During the water injection process, it is necessary to ensure that the liquid level is slightly lower than the top of the washing basket 2 to avoid water overflowing the washing tank 1. The air pump 10 is started, and the gas generated by the air pump 10 is transmitted to the diversion pipe 12 through the delivery pipe 11 and released by the aeration plate 13. The microporous structure on the surface of the aeration plate 13 allows the gas to be evenly released into the water in the form of tiny bubbles with a diameter of 0.1-0.5mm. These tiny bubbles generate strong bubble disturbance during their ascent, pushing the fruit to turn over in the washing basket 2, while applying a gentle impact force to the surface of the fruit. This not only avoids the problem of fruit damage caused by excessive force in traditional washing methods, but also significantly enhances the disturbance ability of the water flow, eliminates washing dead corners, and ensures that the surface of the fruit is thoroughly cleaned.

[0021] After cleaning, the operator removes the cleaning basket 2 from the cleaning tank 1 using handle 9. The controller 7 sends a signal to open valve 15 on the outlet pipe 5, discharging the wastewater. When an electrically controlled valve is used, the controller 7 sends a signal via a wire to control valve 15 to open; when a manual valve is used, the operator needs to manually rotate the handle of valve 15 to complete the drainage operation, thus completing the entire cleaning process.

[0022] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
