Description

Technical Field

[0001] The present disclosure relates to the technical field of fruit and vegetable washing machines, and in particular to an aeration plate and a fruit and vegetable washing machine. Background Art

[0002] A fruit and vegetable washer is a device used to clean fruits and vegetables. During the cleaning process, an ozone generator within the machine generates ozone, which is then pumped through a pipe to the washing tank by an ozone pump, where it dissolves into the water. Ozone-infused water has a strong bactericidal, disinfecting, and pesticide-degrading effect. Ozone directly destroys the chemical bonds in pesticides and the biological structure of harmful bacteria, transforming them into stable inorganic compounds, ensuring greater safety. Furthermore, the machine can oxidize water-soluble heavy metal ions into insoluble, non-toxic, high-valent compounds that are then precipitated and separated, effectively removing heavy metal ions from the surface of fruits and vegetables.

[0003] The utility model with the authorization announcement number CN215198583U discloses a magnetic aeration plate, aeration equipment and a cleaning tank, including a shell and an inner cavity, a plurality of aeration holes are distributed on the upper surface of the shell, each aeration hole is connected to the inner cavity, and a support is provided on the lower surface of the shell, and the lower end surface of the support is concave to form a groove, and a magnetic element is provided in the groove. The above-mentioned magnetic aeration plate is applied to the aeration equipment and the cleaning tank, which can be easily installed and disassembled. However, the structural setting of the aeration plate will make the aeration holes located around the air inlet have a larger air output, while the aeration holes away from the air inlet have a smaller air output, which makes the bubbles in the washing tank of the fruit and vegetable washing machine unevenly distributed, and the number of bubbles at different positions varies greatly, resulting in poor cleaning effect on fruits and vegetables. Utility Model Content

[0004] In response to the deficiencies or problems in the prior art, the present disclosure provides an aeration plate and a fruit and vegetable washing machine. The aeration plate has a reasonable structure, which can make the bubble distribution at different positions in the fruit and vegetable washing machine more uniform and achieve better cleaning effect.

[0005] The technical solution adopted by the present disclosure to solve the above-mentioned technical problems is: an aeration plate, comprising an upper plate body and a lower plate body covering each other, a plurality of aeration holes evenly distributed on the upper plate body, an air inlet cavity formed between the upper plate body and the lower plate body, the upper plate body being provided with a first mounting hole and a second mounting hole, the corresponding positions of the lower plate body being provided with a first through hole and a second through hole, the first mounting hole and the first through hole being used to connect to a first air supply mechanism, and the second mounting hole and the second through hole being used to connect to a second air supply mechanism.

[0006] As a preferred embodiment, the first mounting hole and the second mounting hole are arranged on both sides of the upper plate body. After the first air supply mechanism is connected to the first mounting hole and the first through hole, the air inlet valve of the first air supply mechanism will protrude from the upper plate body. Similarly, after the second air supply mechanism is connected to the second mounting hole, the air inlet valve of the second air supply mechanism will also protrude from the upper plate body. The first mounting hole and the second mounting hole are arranged on both sides of the upper plate body, and the middle position is used to place the fruits and vegetables to be cleaned. This can avoid the air inlet valve protruding from the upper plate body affecting the cleaning effect. In addition, the first mounting hole and the second mounting hole are arranged on both sides of the upper plate body, and the gas can enter the air inlet cavity from both sides respectively, and then flow out from the aeration hole. This can ensure the uniformity of the gas outlet of the aeration hole and avoid the small amount of gas outlet on the side, which affects the cleaning effect.

[0007] As a preferred embodiment, a first air intake channel and a second air intake channel are provided in the air intake cavity, the first air intake channel is provided in the middle of the upper plate body and the lower plate body, the second air intake channel is provided close to the edge of the upper plate body and the lower plate body, and the second air intake channel is provided around the first air intake channel.

[0008] As a preferred embodiment, the upper plate body is provided with a first ridge, the first air intake channel is provided on the inner side of the first ridge, the second air intake channel is provided on the outer side of the first ridge, the first mounting hole is partially located in the first air intake channel and partially located in the second air intake channel, and the second mounting hole is partially located in the first air intake channel and partially located in the second air intake channel.

[0009] As a preferred embodiment, the lower plate body is provided with a second ridge, the position of the second ridge corresponds to the position of the first ridge, the lower end surface of the first ridge is in contact with the upper end surface of the second ridge, the first air intake channel is provided on the inner side of the second ridge, and the second air intake channel is provided on the outer side of the second ridge.

[0010] As a preferred embodiment, a plurality of air outlets are evenly distributed on the lower plate.

[0011] In a preferred embodiment, the air outlets include a plurality of first air outlets disposed in the first air inlet channel and a plurality of second air outlets disposed in the second air inlet channel. The arrangement of the first and second air outlets allows a small portion of air in the first and second air inlet channels to enter the lower portion of the lower plate at a constant flow rate. This reduces residual dirt below the lower plate, i.e., at the bottom of the washing tank, after washing, and accelerates drainage of the washing tank.

[0012] As a preferred embodiment, the upper plate body is provided with a first plane, the first plane is located in the middle of the upper plate body, the upper plate body is provided with two first inclined surfaces along its length direction, the two first inclined surfaces are arranged on both sides of the length direction of the first plane, the upper plate body is provided with two second inclined surfaces along its width direction, the two second inclined surfaces are arranged on both sides of the width direction of the first plane, and the distance from the first plane to the lower plate body is greater than the distance from the first inclined surface and the second inclined surface to the lower plate body.

[0013] Compared with existing products, the first air supply mechanism is connected through the first mounting hole and the first through hole, and the second air supply mechanism is connected through the second mounting hole and the second through hole. The two air supply mechanisms simultaneously transport gas to the air inlet cavity. The gas can fill the air inlet cavity faster and flow out evenly from the aeration holes, thereby ensuring a uniform distribution of the number of bubbles.

[0014] Another object of the present disclosure is to provide a fruit and vegetable washing machine, comprising a washing tank and the above-mentioned aeration plate, wherein the washing tank comprises a side wall and a bottom wall, and the aeration plate is arranged on the bottom wall.

[0015] As a preferred embodiment, the lower plate is provided with multiple support protrusions for supporting the aeration plate. This arrangement ensures that, when the aeration plate is placed in the washing tank, sufficient clearance is left between the lower plate and the bottom wall of the washing tank. Dirt from washed fruits and vegetables accumulates in this clearance, and the air flowing out of the first and second air outlets carries the dirt from this clearance toward the drain outlet.

[0016] Compared with existing products, by adopting the aeration plate of the present application, the bubbles in the cleaning tank can come out of the aeration plate and enter the cleaning tank at a faster speed to clean the fruits and vegetables, thereby improving the cleaning efficiency of the fruit and vegetable washing machine; at the same time, the bubbles can come out of the aeration plate and enter the cleaning tank evenly, thereby ensuring that the bubbles are evenly distributed in the cleaning tank to clean fruits and vegetables in different positions, thereby improving the cleaning effect of the fruit and vegetable washing machine.

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is described in detail, clearly, and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

[0027] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0028] Please see Figure 1 and Figure 2As shown, an embodiment of the present application provides an aeration plate, comprising an upper plate body 1 and a lower plate body 2 that cover each other. The upper plate body 1 and the lower plate body 2 are roughly rectangular structures. The upper plate body 1 and the lower plate body 2 are welded together by a hot plate. A plurality of aeration holes 3 are evenly distributed on the upper plate body 1. An air inlet cavity is formed between the upper plate body 1 and the lower plate body 2. The upper plate body 1 is provided with a first mounting hole 4 and a second mounting hole 5. The corresponding positions of the lower plate body 2 are provided with a first through hole 6 and a second through hole 7. The first mounting hole 4 and the first through hole 6 are used to connect to a first air supply mechanism, and the second mounting hole 5 and the second through hole 7 are used to connect to a second air supply mechanism. The first air supply mechanism and the second air supply mechanism are both mechanisms for providing ozone. The ozone providing mechanism is also connected to an air pump. Under the action of the air pump, the ozone in the ozone providing mechanism enters the air inlet cavity. The aeration plate aerates the air and ozone entering the air inlet cavity to produce bubbles of appropriate size and uniform distribution. The present application connects the first air supply mechanism through the first mounting hole 4 and the first through hole 6, and connects the second air supply mechanism through the second mounting hole 5 and the second through hole 7. The two air supply mechanisms simultaneously deliver gas to the air inlet cavity, and the gas can fill the air inlet cavity faster and flow out evenly from the aeration hole 3, thereby ensuring a uniform distribution of the number of bubbles.

[0029] Furthermore, the first mounting hole 4 and the second mounting hole 5 are respectively arranged on both sides of the upper plate body 1, and the first through hole 6 and the second through hole 7 are arranged on both sides of the lower plate body 2. After the first air supply mechanism is connected to the first mounting hole 4 and the first through hole 6, the air inlet valve of the first air supply mechanism will protrude from the upper plate body 1. Similarly, after the second air supply mechanism is connected to the second mounting hole 5, the air inlet valve of the second air supply mechanism will also protrude from the upper plate body 1. The first mounting hole 4 and the second mounting hole 5 are arranged on both sides of the upper plate body 1, and the middle position is used to place the fruits and vegetables to be cleaned. This can prevent the air inlet valve protruding from the upper plate body 1 from affecting the cleaning effect. In addition, by arranging the first mounting hole 4 and the second mounting hole 5 on both sides of the upper plate body 1, gas can enter the air inlet cavity from both sides respectively. The gas on both sides of the air inlet cavity gradually spreads to the middle of the air inlet cavity and fills the entire air inlet cavity, and then flows out from the aeration hole 3. This can ensure the uniformity of the bubbles emitted by the aeration hole 3 and avoid the small amount of gas discharged from the side, which affects the cleaning effect.

[0030] For further information, please also refer to Figure 6As shown, two raised structures 8 are provided on the upper plate body 1, and the first mounting hole 4 and the second mounting hole 5 are respectively provided on the two raised structures 8. Specifically, the air intake valve is connected to the aeration plate by plugging and unplugging, and a portion of the air intake valve structure protrudes from the surface of the upper plate body 1. The raised structure 8 is a U-shaped protrusion protruding from the surface of the upper plate body 1. A stepped surface is formed at the transition position between the raised structure 8 and the upper plate body 1, so that the height of the first mounting hole 4 and the second mounting hole 5 is slightly higher than the plate surface of the upper plate body 1, preventing fruits and vegetables from touching the air intake valve, causing damage to the fruit and vegetable skin or loosening of the air intake valve. In particular, at least three aeration holes 3 are provided at the transition position between the raised structure 8 and the upper plate body 1 (around the raised structure 8). The three aeration holes 3 are respectively provided on the left, right and upper sides of the raised structure 8, so that there are certain bubbles around the raised structure 8 to clean the fruits and vegetables around the raised structure 8.

[0031] like Figure 3-Figure 5As shown, in order to further ensure the uniformity of the number of bubbles at the edge and the middle of the aeration plate, a first air inlet channel 10 and a second air inlet channel 11 are provided in the air inlet cavity. The first air inlet channel 10 is provided in the middle of the upper plate body 1 and the lower plate body 2, and the second air inlet channel 11 is provided near the edges of the upper plate body 1 and the lower plate body 2. The second air inlet channel 11 is provided around the first air inlet channel 10. Specifically, the upper plate body 1 is provided with a first rib 12, the first air inlet channel 10 is provided on the inner side of the first rib 12, and the second air inlet channel 11 is provided on the outer side of the first rib 12. The lower plate body 2 is provided with a second rib 13. The position of the second rib 13 corresponds to that of the first rib 12. The lower end surface of the first rib 12 is in contact with the upper end surface of the second rib 13. The first air inlet channel 10 is provided on the inner side of the second rib 13, and the second air inlet channel 11 is provided on the outer side of the second rib 13. That is, when the upper plate 1 and the lower plate 2 are closed together, the first ridge 12 and the second ridge 13 divide the air inlet cavity into a first air inlet channel 10 and a second air inlet channel 11, and the second air inlet channel 11 is arranged around the first air inlet channel 10. The first mounting hole 4 is partially located in the first air inlet channel 10 and partially located in the second air inlet channel 11. Part of the ozone provided by the first air supply mechanism enters the first air inlet channel 10 and part of it enters the second air inlet channel 11. The second mounting hole 5 is partially located in the first air inlet channel 10 and part of it enters the second air inlet channel 11. Part of the ozone provided by the second air supply mechanism enters the first air inlet channel 10 and part of it enters the second air inlet channel 11. This arrangement ensures that the middle position and the edge position each have their own air intake channels. The gas in the first air intake channel 10 hardly enters the second air intake channel 11, and the gas in the second air intake channel 11 hardly enters the first air intake channel 10. As a result, the gas entering the second air intake channel 11 only flows at the edge of the air intake cavity, and the gas entering the first air intake channel 10 only flows at the middle of the air intake cavity. This can avoid the situation where the gas at the edge of the air intake cavity is scarce due to the gas converging to the middle of the air intake cavity.

[0032] Please continue to see Figure 5 As shown, in one embodiment of the present disclosure, a plurality of air outlets are evenly distributed on the lower plate 2. Specifically, the air outlets include a plurality of first air outlets 14 provided in the first air inlet channel 10 and a plurality of second air outlets 15 provided in the second air inlet channel 11. The arrangement of the first air outlets 14 and the second air outlets 15 allows a small portion of the air in the first air inlet channel 10 and the second air inlet channel 11 to enter the lower portion of the lower plate 2 at a certain flow rate, accelerating the flow of dirt from the bottom of the tank. This can reduce the amount of dirt remaining below the lower plate 2, i.e., at the bottom of the washing tank, after washing, accelerate the drainage of the washing tank, and effectively prevent the drain from clogging.

[0033] like Figure 6As shown, preferably, the upper plate body 1 is provided with a first plane, the first plane is located in the middle position of the upper plate body 1, the first air intake channel 10 is located below the first plane, the upper plate body 1 is provided with two first inclined surfaces 16 along its length direction, the two first inclined surfaces 16 are arranged on both sides of the length direction of the first plane, the first mounting hole 4 and the second mounting hole 5 are located on the first inclined surfaces 16, the upper plate body 1 is provided with two second inclined surfaces 17 along its width direction, the two second inclined surfaces 17 are arranged on both sides of the width direction of the first plane, the second air intake channel 11 is located below the first inclined surface 16 and the second inclined surface 17, and the distance from the first plane to the lower plate body 2 is greater than the distance from the first inclined surface 16 and the second inclined surface 17 to the lower plate body 2. Since the second air inlet channel 11 is arranged around the first air inlet channel 10, the path taken by the gas when filling the second air inlet channel 11 is longer, and the time required for the gas to fill the second air inlet channel 11 is also longer. Setting the height of the second air inlet channel 11 lower than the height of the first air inlet channel 10 can greatly reduce the time difference between the gas filling the second air inlet channel 11 and filling the first air inlet channel 10, so that the aeration holes 3 located in the second air inlet channel 11 and the aeration holes 3 located in the first air inlet channel 10 can be bubbled almost at the same time.

[0034] Another embodiment of the present application provides a fruit and vegetable washing machine, comprising a washing tank, the washing tank comprising side walls and a bottom wall, and the aeration plate described above is arranged on the bottom wall. Figure 2 As shown, preferably, four supporting protrusions 9 are provided on the lower plate body 2. The four supporting protrusions 9 are respectively located at the four corners of the lower surface of the lower plate body 2 to support the aeration plate. The lower end surfaces of the supporting protrusions 9 are in contact with the cleaning tank. The arrangement of the supporting protrusions 9 ensures that after the aeration plate is placed in the cleaning tank, there is a sufficient gap between the lower plate body 2 and the bottom wall of the cleaning tank. The stains removed from the fruits and vegetables will be deposited in this gap. The gas flowing out of the first air outlet 14 and the second air outlet 15 will carry the stains in this gap to the sewage outlet, thereby accelerating the sewage discharge speed and preventing blockage.

[0035] The present application has been described in detail above. Specific examples have been used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is intended only to facilitate understanding of the present application and its core concepts. It should be noted that, without departing from the principles of the present application, a number of improvements and modifications may be made to the present application by a person skilled in the art, and such improvements and modifications shall fall within the scope of protection of the claims of the present application.
