Description

Technical Field

[0001] This application belongs to the technical field of food cleaning equipment, and in particular relates to an impeller for a fruit and vegetable cleaning machine. Background Technology

[0002] Currently, fruit and vegetable washing machines generally use impeller rotation to generate water flow for rinsing and cleaning fruits and vegetables. Various impeller structures for fruit and vegetable washing machines have been disclosed in existing technologies, such as impellers with several straight or curved blades. A motor drives the blades to rotate and agitate the water, creating a circulating flow to remove dirt from the surface of fruits and vegetables. However, these traditional impellers still have significant shortcomings in practical applications: Firstly, their water guiding structure is relatively simple, usually relying solely on the direct pushing of the water by the sides of the blades. The water flow direction is unidirectional (mainly circumferential rotation or simple axial flow), making it difficult to form a three-dimensional, uniform, and multi-layered circulating flow field inside the tank. This leads to dead zones within the washing machine, insufficient water flow intensity in some areas, and fruits and vegetables not being thoroughly rinsed. Secondly, the blade design lacks precise control over the water flow pattern, often generating a large amount of turbulence and energy dissipation. This not only reduces cleaning efficiency but also increases motor load and operating noise, resulting in high energy consumption. In addition, the water flow generated by traditional impellers is relatively rigid, which can easily cause mechanical damage to fruits and vegetables with delicate skins, such as strawberries and leafy greens, affecting their marketability and edibility.

[0003] To address the aforementioned issues, some improvement solutions have been optimized by adding a flow guide or changing the blade angle, but these solutions have not fundamentally resolved the problems of low water flow guidance efficiency, poor cleaning uniformity, and insufficient protection of fruits and vegetables.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, by arranging various types of water-guiding components (including water-guiding blades, water-guiding rings, hollow columns, and water-passing discs) in an array at the top of the base, and setting a transmission component connected to the motor in the middle of the base, the impeller can form a multi-dimensional, multi-level three-dimensional water-guiding channel when rotating.

This ensures smooth water flow while generating appropriate eddies and disturbances, causing fruits and vegetables to tumble and rub against each other during the washing process. This improves the uniformity of washing and the removal rate of stubborn stains, while preventing fruits and vegetables from piling up or being crushed. The design also effectively reduces the fluid resistance and vibration noise of the impeller, reduces motor load and energy consumption, and extends the service life of the entire machine. Furthermore, various water-guiding component structures can be flexibly selected according to different types of fruits and vegetables, washing intensity, and water tank size.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Please see the appendix Figure 1 - Appendix Figure 14 This application provides a technical solution: an impeller for a fruit and vegetable washing machine, including a base 1, wherein a water guiding component is arranged on the top of the base 1; A transmission component connected to a motor is provided in the middle of the base 1; One side of the water guiding component in the array is connected to the base 1, and the other side is connected to the transmission component.

[0021] The specific implementation method is as follows: the water guiding component includes a first hollow column 101, the top of the base 1 is arrayed with a first water guiding blade 102, the top of the first water guiding blade 102 is provided with a plurality of first water guiding through holes 103, the bottom of the first water guiding blade 102 is provided with a water blocking groove 104, the shape of the water guiding component is a hollow water permeable column arrayed in the middle of the base 1, and the shape of the first water guiding blade 102 is hollow at the bottom and its surface is tilted to the side.

[0022] By setting a base 1, arranging water guiding components in an array on the top of the base 1, and arranging a transmission component connected to a motor in the middle of the base 1, and connecting one side of the water guiding component to the base 1 and the other side to the transmission component, the water guiding component can rotate stably and generate efficient water circulation when the motor drives the transmission component to rotate. Specifically, the water guiding component includes a first hollow column 101 and a first water guiding blade 102 arrayed on the top of the base 1. The top of the first water guiding blade 102 has multiple sets of first water guiding holes 103, and the bottom has a water blocking groove 104. At the same time, the overall shape of the water guiding component is a hollow permeable column arrayed in the middle of the base 1. The water guide blade 102 is hollow at the bottom and tilted on the surface. The above structures work together to guide water upward from the bottom when the impeller rotates. The tilted first water guide blade 102 generates an upward thrust. The first water guide hole 103 and the hollow water column realize multiple diversion and guidance of the water flow. The water blocking groove 104 locally changes the water flow speed to create disturbance, thereby significantly improving the water head and coverage area. A three-dimensional and uniform circulating water flow is formed inside the washing machine, effectively avoiding cleaning dead corners and enhancing the rinsing force on the surface of fruits and vegetables. At the same time, the hollow structure at the bottom reduces the overall weight of the impeller, reduces the motor load and operating noise, and extends the service life of the whole machine.

[0023] like Figure 12The water guiding component includes a fourth hollow column 10, the top of which is equipped with a tenth water guiding blade 1001, and a ninth water guiding ring 1002 is covered and installed on one side of the tenth water guiding blade 1001.

[0024] like Figure 13 The water guiding component includes a fifth hollow column 11, an eleventh water guiding blade 1101 is mounted on the surface of the fifth hollow column 11, and a tenth water guiding ring 1102 is covered and mounted on one side of the eleventh water guiding blade 1101.

[0025] like Figure 14 The water guiding component includes a sixth hollow column 12, on the surface of which a twelfth water guiding blade 1201 is mounted in an array, and an eleventh water guiding ring 1202 is mounted on one side of the twelfth water guiding blade 1201.

[0026] Example 1: This example differs from the above examples in that it includes a first water-passing impeller 2, an arc-shaped first water-passing impeller 2, and a second water-guide blade 201, and a transmission gear is added to the bottom of the base 1.

[0027] Specifically, such as Figure 3 Figure 4 As shown, the central channel of the first water turbine 2 allows water to flow through the central water guide channel and be discharged in a concentrated manner, resulting in higher head and more concentrated flushing.

[0028] Example 2; This example differs from the above examples in that the third water guide blade 301 is a triangular single plate with a larger tilt angle than in Example 1, the second water guide ring 302 covers the upper half of the blade rather than the side, the middle of the second water-passing wheel 3 is a central channel, and the blades are arranged radially at equal angles.

[0029] Specifically, such as Figure 5 As shown, the triangular single-plate blades and the upper water guide ring work together to form a double-layer water guide channel, which guides the water flow in layers and enhances the turbulence, significantly improving the uniformity of washing and preventing local accumulation of fruits and vegetables.

[0030] Example 3; This example differs from the above examples in that the fourth water guide blade 401 is a right-leaning single plate with an inclination angle greater than that in Example 2, the third water guide ring 402 covers the middle of the blade rather than the upper end, and the through holes in the middle of the third water-passing wheel 4 are arranged in an equal-angle ring.

[0031] Specifically, such as Figure 6 As shown, this structure forms a double-layer water guiding channel, which makes the water flow more smoothly, reduces turbulence energy consumption, and provides gentler cleaning with wider coverage.

[0032] Example 4; This example differs from the above examples in that the fourth water-passing wheel 5 is concave in the middle of its shape, the fifth water-guide blade 501 is a right-leaning long strip plate that fits against the concave surface, the fourth water-guide ring 502 only covers the upper half of the blade, and the second water-guide holes 503 are evenly distributed in a ring array on the surface of the wheel.

[0033] Specifically, such as Figure 7 As shown, the concave structure guides the water flow to converge at the center and then swirls outwards, forming an enveloping cleaning effect that effectively eliminates blind spots in the cleaning process.

[0034] Example 5; This example differs from the above examples in that the surface of the fifth water-passing impeller 6 is inclined, the central array is provided with a left-leaning single-plate first water-blocking connecting plate 601, the sixth water-guide blade 602 is a right-leaning single plate that fits the inclined surface, the fifth water-guide ring 603 covers the middle of the blade, and the third water-guide through hole 604 is arranged in multiple rings.

[0035] Specifically, such as Figure 8 As shown, the left-tilted water-blocking plate and the right-tilted blades are in opposite directions, forming a counter-current flow and increasing eddy current disturbance. At the same time, the central permeable channel ensures the flow rate, significantly improving the ability to remove stubborn stains.

[0036] Example 6; This example differs from the above examples in that one end of the blade 701 is fixed to the plane and the other end is attached to the groove, and it is set across the inclined plane, and a first water-permeable groove 702 is opened between the blades instead of a through hole.

[0037] Specifically, such as Figure 9 As shown, the cross-channel blades, in conjunction with the permeable gap, allow for a smooth water flow transition and generate controllable eddies, avoiding turbulent impacts.

[0038] Example 7; This example differs from the above examples in that the second hollow column 8 is radially divided into multiple fan-shaped areas, each area is provided with multiple parallel slender through grooves instead of round holes, the eighth water guide blade 801 is a right rear inclined single plate, and the seventh water guide ring 802 covers the upper half of the blade.

[0039] Specifically, such as Figure 10 As shown, the fan-shaped parallel slots combined with the oblique blades form multiple streams, resulting in a more uniform water flow distribution and avoiding excessive local scouring.

[0040] Example 8; This example differs from the above examples in that the third hollow column 9 is composed of multiple identical fan-shaped units that are evenly distributed radially around the center, and there are no parallel grooves within the units.

[0041] Specifically, such as Figure 11 As shown, the radial units are arranged at equal angles, and the water flow spreads radially, covering a wider area without overlapping eddies.

[0042] Example 9; This example differs from the above examples in that the fourth hollow column 10 has a cylindrical radial array structure, the tenth water guide blade 1001 is a left-leaning arc plate instead of a right-leaning single plate, and the ninth water guide ring 1002 covers the middle and lower part of the blade.

[0043] Specifically, such as Figure 12 As shown, the left-leaning arc plate guides the reverse swirling flow to counteract the mainstream flow, enhancing the kneading disturbance and facilitating the removal of stubborn stains.

[0044] Example 10; This example differs from the above examples in that the fifth hollow column 11 has a cross-shaped partition structure, dividing the interior into four symmetrical quadrants; the eleventh water guide vane 1101 is an upright flat plate rather than an inclined single plate.

[0045] Specifically, such as Figure 13 As shown, the upright flat plate combined with the cross-shaped divider generates vertical water flow shear force, which is suitable for gently washing fragile fruits and vegetables and avoiding damage to the skin.

[0046] Example 11: This example differs from the above examples in that the sixth hollow column 12 has a concentric ring-shaped hollow structure, and the twelfth water guide blade 1201 is a wavy curved surface rather than a flat plate.

[0047] Specifically, such as Figure 14 As shown, the wavy surface combined with the annular hollow design generates pulsed water flow, which enhances the impact frequency and improves the cleaning efficiency.

[0048] Working Principle: The impeller and the top array of water guide components are driven to rotate synchronously at high speed through the transmission component in the middle of the base 1 connected to the motor. The centrifugal force generated by the rotation creates a low-pressure zone at the bottom center of the impeller, which draws water from the washing machine's tank into the impeller. The water is then forced to change from an axial suction direction to a radial (outward) and axial (upward) spray direction by the directional constraint of the array of water guide components connected to the base on one side and the transmission component on the other, forming multiple evenly distributed drainage channels. The high-speed water jet generates a three-dimensional circulating water flow in the tank, flowing from top to bottom, from the center outward, and then back to the bottom of the impeller. This fully covers the surface of fruits and vegetables, using the flexible impact force of the water flow to remove dirt and cause the fruits and vegetables to tumble and rub against each other, effectively eliminating cleaning dead corners and avoiding damage to the fruit and vegetable skins caused by mechanical hard brushes. In addition, the double-sided connection structure between the water guide components and the base and transmission components significantly enhances the overall rigidity and dynamic balance performance of the impeller, ensuring stable operation during high-speed rotation, reducing noise, and extending the service life of the entire machine.

[0049] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and inventive concept of this application, should be included within the scope of protection of this application.
