Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable cleaning technology, specifically a fruit and vegetable cleaning machine. Background Technology

[0002] People are paying increasing attention to food safety. Nowadays, most foods are sprayed with pesticides, hormones, and preservatives. These harmful substances remain in the food, seriously endangering people's health. Fruits and vegetables purchased by families need to be cleaned using fruit and vegetable washing machines.

[0003] However, current fruit and vegetable washing machines on the market mainly remove impurities from the surface of fruits and vegetables through water jet impact, but this has significant limitations in actual use. Because fruits and vegetables cannot tumble independently during the washing process, the washing range is limited, only cleaning localized areas and resulting in poor overall cleaning effectiveness. To improve this situation, modern cleaning technology generally adopts bubble cleaning to enhance cleaning efficiency. However, existing bubble cleaning systems suffer from insufficient adjustability; they cannot precisely control the bubble spray speed or adjust the bubble particle size according to needs, thus making it difficult to provide differentiated cleaning solutions for different types of fruits and vegetables. Therefore, this invention provides a fruit and vegetable washing machine to solve the aforementioned problems. Summary of the Invention

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 and Figure 2 In Embodiment 1 of the present invention, a fruit and vegetable washing machine includes a washing machine body 100. Support legs 101 are installed at the four corners of the bottom of the washing machine body 100. A control panel 110 for controlling the electrical equipment inside the washing machine body 100 is installed on one side of the top of the washing machine body 100. The control panel 110 has multiple control buttons. A circular slot is opened at the top of the washing machine body 100. A partition plate 130 is fixedly connected to the bottom of the inner wall of the slot to divide the space of the slot. The top chamber of the partition plate 130 is used for washing fruits and vegetables, and the bottom chamber of the partition plate 130 is used for installing equipment. A drain pipe 131 is fixedly connected to the inner wall of the partition plate 130. The drain pipe 131 connects the top chamber of the partition plate 130 to the outside of the cleaning machine body 100. A solenoid valve for controlling the opening and closing is installed inside the drain pipe 131. When cleaning is completed, the solenoid valve on the drain pipe 131 can be opened to discharge the sewage in the top chamber of the partition plate 130. A top cover 120 for opening and closing the slot is rotatably connected to the top of the cleaning machine body 100 adjacent to the control panel 110. A sealing ring for sealing is installed at the bottom of the top cover 120. A glass plate 121 for observation is installed at the slot of the top cover 120. A sealing ring for sealing the slot is installed at the bottom of the top cover 120 at the glass plate 121.

[0038] A cleaning sleeve 200 for storing fruits and vegetables is installed on the inner wall of the cleaning machine body 100 at the top of the partition plate 130. Both ends of the cleaning sleeve 200 have annular grooves, and bolts are installed in the annular grooves. The bolts fit the cleaning sleeve 200 into the inner wall of the cleaning machine body 100. Waterproof rubber strips are installed on the inner wall of the annular grooves to protect the bolts. The waterproof rubber strips can prevent water from corroding and damaging the bolts. A filter plate 210 is slidably connected to the inner wall of the cleaning sleeve 200. The filter plate 210 has multiple filter holes arranged in a circle on its surface. Both ends of the cleaning sleeve 200 have annular ribs. The inner diameter of the ribs is smaller than the diameter of the filter plate 210. The ribs limit the sliding range of the filter plate 210. A telescopic rod 222 for guiding the filter plate 210 is fixedly connected between the top rib and the filter plate 210. The telescopic rod 222 restricts the sliding direction of the filter plate 210 and prevents the filter plate 210 from being misaligned or stuck when sliding.

[0039] The cleaning machine body 100 has a storage box 400 for storing water and gas installed on its side wall. The cleaning machine body 100 has a control box 300 installed at the bottom of the partition plate 130. The storage box 400 has a conveying component for conveying water and gas to the control box 300. The inner wall of the control box 300 has a generating component for mixing water and gas to generate bubbles. The control box 300 also has an adjusting component for controlling the current of the conveying component and the size of the bubbles generated by the generating component. The top of the partition plate 130 and the top of the cleaning sleeve 200 have a spraying component for cleaning fruits and vegetables. The spraying component is connected to the generating component. When fruits and vegetables need to be cleaned, water and gas are conveyed to the generating component through the conveying component. The generating component mixes water and gas to generate bubbles, which are then sprayed through the spraying component to clean the fruits and vegetables. The adjusting component controls the conveying component and the generating component to adapt to different types of fruits and vegetables.

[0040] See Figure 5The conveying assembly includes an air pump 412 and a water pump 421. An isolation plate 401 is fixedly connected to the middle of the inner wall of the storage box 400. A gas storage tank 410 is installed on the top of the inner wall of the storage box 400, storing gas. A mounting bracket 411 is fixedly connected to the outer wall of the gas storage tank 410, and the mounting bracket 411 is bolted to the top outer wall of the isolation plate 401. The air pump 412 is installed on the top outer wall of the storage box 400. An air inlet pipe 413 and an air outlet pipe 414 are respectively installed at the input and output ends of the air pump 412. The air inlet pipe 413 is flush with the inner wall of the gas storage tank 410. The storage box 400 is connected to a water tank 420 fixedly connected to the bottom inner wall. The water tank 420 stores water. A water pump 421 is installed on the bottom outer wall of the storage box 400. The input end and output end of the water pump 421 are respectively equipped with a water outlet pipe 422 and a water delivery pipe 423. The water outlet pipe 422 is connected to the bottom of the water tank 420. By starting the air pump 412, the gas in the air storage tank 410 can be transported to the exhaust pipe 414 through the air inlet pipe 413. By starting the water pump 421, the water in the water tank 420 can be transported to the water delivery pipe 423 through the water outlet pipe 422.

[0041] See Figure 7 and Figure 8 The generating components include a manifold 330 and a fixed channel 331. Both ends of the manifold 330 are fixedly connected to a first flange. The first flange on the manifold 330 is bolted to the inner wall of one side of the control box 300. A water supply pipe 423 is connected to one end of the manifold 330, and an exhaust pipe 414 is connected to the top of the outer wall of the manifold 330. The fixed channel 331 is installed on the inner wall of the manifold 330. The manifold 330 consists of mounting parts at both ends, a throat in the middle, and a transition part between the throat and the mounting parts for communication. The mounting parts are annular and fixedly connected to the inner wall of the manifold 330. The inner diameter of the throat is smaller than that of the mounting parts. The transition part is frustum-shaped and connected to the mounting parts and the throat. When gas and water are transported to the mounting part of the fixed channel 331 through the exhaust pipe 414 and the water supply pipe 423, they can pass through the transition part and enter the throat. The small inner diameter of the throat can accelerate the flow rate of water and gas, improve the efficiency of mixing and generating bubbles, and the bubbles then pass through the throat and the transition part for discharge.

[0042] A transition pipe 340 is installed at one end of the manifold 330, and the transition pipe 340 is connected to one end of the manifold 330. Two second flanges are fixedly connected to both ends of the transition pipe 340. The two second flanges are respectively installed on the inner wall of the control box 300 and the first flange on the manifold 330 by bolts. Multiple linearly arranged conveying channels 341 are formed on the inner wall of the transition pipe 340. The conveying channels 341 are frustoconical in shape, and the diameter of the end of the conveying channel 341 closer to the manifold 330 is larger than the diameter of the end farther from the manifold 330. A one-way rotating block 342 is rotatably connected to the end of the conveying channel 341 away from the manifold 330. One end of channel 341 is rotatably connected to a rotating shaft, and a one-way rotating block 342 is fixedly connected to the outer wall of the rotating shaft. A torsion spring for resetting is installed on the rotating shaft. When the bubble is discharged from the tail end of the fixed channel 331, it can be transported into the transition pipe 340 and impacted by the conveying channel 341, causing the one-way rotating block 342 to rotate and unfold. When there is liquid backflow at the end of the transition pipe 340 away from the collecting pipe 330, the one-way rotating block 342 can close the channel at the conveying channel 341 under the action of the torsion spring, thus preventing the liquid from backflowing into the collecting pipe 330 and affecting the generation of bubbles in the collecting pipe 330.

[0043] See Figure 7 and Figure 9 The adjustment assembly includes a motor 350, a sliding rheostat 351, and an adjusting block 354. The motor 350 is mounted on the top of the inner wall of one side of the control box 300. The motor 350 is connected to the control circuit on the control panel 110 via wiring. The motor 350 is started by a control button. A lead screw 352 is rotatably connected to the output end of the motor 350. The sliding rheostat 351 is mounted on the top inner wall of the control box 300. A sliding end for controlling resistance is mounted on the sliding rheostat 351. The sliding end slides along a metal rod and is limited in one direction. An adjusting block 354 is fixedly connected to the bottom end of the sliding end. The movement of the adjusting block 354 is limited by the movement of the sliding end and can only proceed in the direction of the sliding end's movement. The adjustment block 354 is moved to avoid deflection affecting its position adjustment. The adjustment block 354 is threadedly connected to the outer wall of the lead screw 352. The sliding rheostat 351 is connected in series with the air pump 412 and the water pump 421 in the same circuit. When it is necessary to control the speed of water and gas delivery, the motor 350 is started by the control button. The motor 350 drives the lead screw 352 to rotate. The rotation of the lead screw 352 drives the threaded adjustment block 354 to move. The adjustment block 354 drives the sliding end to move to adjust the resistance of the sliding rheostat 351. At this time, the output current of the air pump 412 and the water pump 421 is controlled, thereby adjusting the speed of water and gas delivery.

[0044] The adjustment assembly also includes an elastic ring 332 and a binding rope 355. The elastic ring 332 is installed on the inner wall of the throat of the fixed channel 331. Multiple mounting ears 333 arranged in a circle are fixedly connected to the outer wall of the elastic ring 332. The binding rope 355 is sleeved on the inner wall of the mounting ears 333, and a winding roller 353 is fixedly connected to the tail end of the screw 352. The binding rope 355 is wrapped around the outer wall of the winding roller 353. When the screw 352 rotates, the winding roller 353 rotates with it, and the binding rope 355 can be released or tightened at the winding roller 353. The binding rope 355 loosens or tightens the elastic ring 332 through the mounting ears 333. The inner diameter of the elastic ring 332 can be adjusted by the elasticity of the elastic ring 332. At this time, the bubbles generated when water and gas are mixed can be adjusted.

[0045] See Figure 4 and Figure 6 The spraying assembly includes a conveyor plate 310, nozzles 311, and a conveying pipe 320. A connecting pipe 302 is connected to the end of a transition pipe 340, and a tee pipe 301 is installed at the end of the connecting pipe 302. An installation pipe 314, connected to the top of the tee pipe 301, is installed at the bottom of the conveyor plate 310. The other end of the conveying pipe 320 is connected to the tee pipe 301. A ring-shaped diverter pipe 321 is connected to the top of the conveyor plate 310. The nozzles 311 are arranged circumferentially on the top of the conveyor plate 310 and on the outer wall of the diverter pipe 321. A connecting pipe 312, connected to both the conveyor plate 310 and the conveying pipe 321, is installed at one end of each nozzle. A spray hole 313 connected to the connecting pipe 312 is provided. When the air bubbles are discharged from the transition pipe 340, they can be transported to the installation pipe 314 and the conveying pipe 320 through the connecting pipe 302 and the three-way pipe 301. The air bubbles in the installation pipe 314 are sprayed through the conveying plate 310 and the connecting pipe 312 and through the spray hole 313 on the nozzle 311, spraying the fruits and vegetables from the bottom. The air bubbles in the conveying pipe 320 can be sprayed from the spray hole 313 on the nozzle 311 through the diversion pipe 321, spraying the fruits and vegetables from the top. When the air bubbles are sprayed onto the fruits and vegetables, they can impact the fruits and vegetables, causing them to float and move on the water surface to turn over, thus cleaning all parts of the fruits and vegetables.

[0046] For more details, please refer to Figure 5 The gas stored in the gas tank 410 is ozone gas. Specifically, when spraying, the bubbles generated by the ozone gas burst when they come into contact with the surface of fruits and vegetables. At this time, the ozone gas can come into contact with the fruits and vegetables, neutralize the pesticide residues in the fruits and vegetables, and improve the cleaning effect on the fruits and vegetables.

[0047] See Figure 10 and Figure 11Multiple linearly arranged diversion grooves 316 are alternately formed on both sides of the inner wall of the spray hole 313. The diversion grooves 316 are arc-shaped, and the inner diameter of the arc surface increases from bottom to top. The top and bottom of the diversion grooves 316 are respectively provided with an upper connecting groove 317 and a lower connecting groove 315 that communicate with the inner wall of the spray hole 313. The opening area of ​​the upper connecting groove 317 is larger than the opening area of ​​the lower connecting groove 315. The bottom end of the lower connecting groove 315 located at the top points to the top end of the upper connecting groove 317 on the other side of the adjacent bottom. When bubbles are discharged from the spray hole 313... The lower connecting groove 315 has a small opening area, making it difficult for air bubbles to enter. Instead, they can be directly discharged from the spray hole 313 for spraying. When external water flows into the spray hole 313, the upper connecting groove 317 has a large opening area, allowing water to enter and be diverted. The diverted water can then pass through the diversion groove 316 and be discharged from the lower connecting groove 315, passing through another upper connecting groove 317. This creates a circulation within the diversion groove 316, making it difficult for the water to pass through the spray hole 313, thus preventing backflow and ensuring proper air bubble spraying.

[0048] See Figure 3 A connecting rod 220 is rotatably connected between the glass plate 121 and the filter plate 210. A rotating seat is installed at one end of each glass plate 121 and the filter plate 210. A rotating pin is fixedly connected to the inner wall of the rotating seat. A through rotating hole is opened at both ends of the connecting rod 220. The rotating pin is rotatably connected to the inner wall of the rotating hole. A brush cylinder 221 is installed on the outer wall of the connecting rod 220. The brush cylinder 221 is made of flexible material. When the top cover 120 is opened, the filter plate 210 is pulled by the rotation of the connecting rod 220. The filter plate 210 is pulled and can move upward along the extension direction of the telescopic rod 222, so that the filter plate 210 can be moved to the top for easy placement and removal of fruits and vegetables. When washing, the top cover 120 is closed, and the filter plate 210 moves downward with the rotation of the connecting rod 220, so that the fruits and vegetables can be immersed in water for washing.

[0049] In the second embodiment of the present invention, the conveyor disc 310 is rotatably connected to the top of the mounting pipe 314, and the connecting pipe 312 is installed at an incline on the top of the conveyor disc 310. Multiple connecting pipes 312 point in the same direction and have the same angle with the top of the conveyor disc 310. When the bubbles are sprayed from the spray hole 313, the reaction force generated by the bubbles can generate a unidirectional torque, which can push the conveyor disc 310 to rotate on the top of the mounting pipe 314. Then, the sprayed bubbles turbulent the water under the action of centrifugal force. The water is disturbed and generates eddies, which drive the fruits and vegetables to rotate and turn over in the water, avoiding spray dead angles and affecting the cleaning effect.

[0050] The working principle of this invention is as follows: When cleaning is required, the top cover 120 is opened to add water to the washing machine body 100, fruits and vegetables are placed on top of the filter plate 210, and then the top cover 120 is closed. At this time, the filter plate 210 is moved to the bottom by the connecting rod 220, immersing the fruits and vegetables in water. Immediately afterwards, the air pump 412 and water pump 421 are turned on to deliver gas and water to the collecting pipe 330. The gas and water mix at the fixed channel 331 to generate bubbles. The bubbles pass through the transition pipe 340 and the connecting pipe 3 02 The air is delivered to the three-way pipe 301, and then the air bubbles are sprayed from the spray hole 313 through the installation pipe 314 and the conveying plate 310. The air bubbles are also sprayed from the spray hole 313 through the conveying pipe 320 and the diversion pipe 321. This allows the fruits and vegetables to be sprayed and cleaned from the bottom and top. After cleaning, the solenoid valve of the drain pipe 131 is opened to drain the water, and the top cover 120 is opened to move the filter plate 210 to the top. The fruits and vegetables are placed on the top of the filter plate 210 to drain the residual water. Finally, the fruits and vegetables are taken out.

[0051] When the type of fruit and vegetable changes, the motor 350 is turned on by the control button on the control panel 110. The motor 350 drives the adjusting block 354 to move through the lead screw 352. The adjusting block 354 drives the sliding end of the sliding rheostat 351 to move, changing the resistance connected to the air pump 412 and the water pump 421. This allows for adjustment of the output current of the air pump 412 and the water pump 421, thereby controlling the flow rate of water and gas and thus controlling the spraying speed.

[0052] Rotating the lead screw 352 tightens and loosens the binding rope 355 via the winding roller 353, thereby adjusting the length of the binding rope 355 wrapped around the mounting ear 333. The elasticity of the elastic ring 332 allows for adjustment of the inner diameter of the elastic ring 332, which in turn controls the size of the bubbles generated when water and gas are mixed.

[0053] When in use, this invention, through the set conveying component, generating component, adjusting component and spraying component, can rinse fruits and vegetables by spraying bubbles at the bottom and top. When the bubbles come into contact with the fruits and vegetables, they burst and impact the fruits and vegetables, helping the fruits and vegetables to turn over in the water, making it convenient to rinse all parts of the fruits and vegetables, improving the cleaning effect of fruits and vegetables, and can control the speed and size of the bubble spraying to adapt to different types of fruits and vegetables.

[0054] With the connecting rod 220 and brush cylinder 221, the filter plate 210 can be pulled to the top when the top cover 120 is opened, making it convenient to place and take out fruits and vegetables. When the fruits and vegetables are impacted by air bubbles, they float and come into contact with the brush cylinder 221, which can then be used to scrub the fruits and vegetables, improving the cleaning effect.

[0055] By using the conveying channel 341, the one-way rotating block 342, and the diversion channel 316, the opening and closing of the one-way rotating block 342 can prevent liquid from flowing back into the fixed channel 331, which would affect the generation of bubbles. It can also prevent the cleaning water from flowing back into the spray hole 313, which would affect the spraying of bubbles, and prevent impurities in the water from clogging the spray hole 313, which would further affect the spraying of bubbles.

[0056] The conveyor plate 310 and nozzle 311 can generate a unidirectional continuous torque during spraying, which turbulent the water and helps the fruits and vegetables to turn over in the water, avoiding dead corners and affecting the cleaning effect.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
