[0032] Reference Figures 1 to 4 This utility model proposes a fruit washing machine 1.
[0033] In an embodiment of the present utility model, the integrated fruit cleaning machine 1 includes a housing 10, which forms an installation cavity 10a and a cleaning tank 10b; a fruit holding basket 20 is accommodated in the cleaning tank 10b and is detachably connected to the housing 10. The fruit holding basket 20 is provided with a holding groove 21a and a plurality of flow holes 21b, and the plurality of flow holes 21b connect the cleaning tank 10b and the holding groove 21a; a cleaning brush 30 is accommodated in the holding groove 21a and is coaxially arranged with the fruit holding basket 20; an eddy current generating mechanism 40 includes a mounting base 41, a water inlet pipe 42 and an eddy current pump. The mounting base 41 is arranged at the bottom of the cleaning tank 10b and is provided with two water inlets 41a that connect the cleaning tank 10b and the installation cavity 10a. Along the circumferential direction of the mounting base 41, the water inlet directions of the two water inlets 41a are arranged in opposite directions. The eddy current pump is installed in the installation cavity 10a and is provided with a water inlet end and a water outlet end. The water inlet pipe 42 is connected to the two water inlets 41a and the water outlet end.
[0034] Specifically, the housing 10 includes a shell (not shown in the figure) and a cleaning base (not shown in the figure). The shell is made of plastic material and forms an installation cavity 10a. The cleaning base is fixedly connected to the shell by screws and forms a cleaning tank 10b. The overall shape of the housing 10 is "convex".
[0035] The fruit holding basket 20 includes a main body 21 and two insertion columns 22 connected to opposite sides of the main body 21. Among them, the overall shape of the main body 21 is a cylindrical grid structure. The main body 21 forms a holding groove 21a and a plurality of flow holes 21b. The holding groove 21a is used to hold fruits to be cleaned. The plurality of flow holes 21b are spacedly arranged on the side wall surface of the main body 21 and connect the holding groove 21a and the cleaning tank 10b. The plurality of flow holes 21b enable the water flow in the cleaning tank 10b to flow into the holding groove 21a. Two insertion columns 22 are integrally formed on the upper part of the main body 21. Two insertion holes 10c are provided at the notch of the cleaning tank 10b, that is, two insertion holes 10c are provided on the upper part of the cleaning base. The main body 21 is placed in the cleaning tank 10b, and one insertion column 22 is inserted into one insertion hole 10c to connect and fix the main body 21 and the cleaning base, so as to prevent the main body 21 from rotating relative to the cleaning base during the cleaning process.
[0036] The mounting base 41 of the vortex generating mechanism 40 is disc-shaped and can be fixed to the bottom of the cleaning tank 10b by screws or heat fusion. Two water inlets 41a are formed on the mounting base 41 by machining or molding. The water inlet directions of the two water inlets 41a are opposite along the circumference of the mounting base 41. This can be understood as the two water inlets 41a facing the same direction in either a clockwise or counterclockwise direction, thus forming a rotating vortex when water is introduced. A vortex pump (not shown) is installed inside the mounting cavity 10a and has an inlet and an outlet. An inlet pipe 42 connects to the two water inlets 41a and the outlet, meaning the vortex pump can simultaneously supply water to both water inlets 41a.
[0037] In this application, the fruit to be cleaned is placed in the cleaning tank 10b. A vortex pump injects cleaning water into the cleaning tank 10b through two inlets 41a. Since the water inlets 41a are arranged in opposite directions, a rotating vortex flow is formed in the cleaning tank 10b. Through multiple flow holes 21b, the vortex flow drives the fruit to be cleaned to rotate in the receiving tank 21a. During the rotation cleaning process, the cleaning brush 30 can also clean the surface of the fruit simultaneously. Using this application, on the one hand, there is no need to use a stirring rod to agitate the fruit, which can rotate and clean the fruit, thus avoiding damage to the skin or flesh to a large extent and making the cleaned fruit more aesthetically pleasing; on the other hand, the coaxially arranged cleaning brush 30 can scrub the surface of the fruit while it rotates, so the integrated fruit cleaning machine 1 has a better cleaning effect on the fruit.
[0038] It should be noted that in actual use, the size of the fruit to be washed should be smaller than the size of the overflow hole 21b to avoid the fruit flowing out of the overflow hole 21b during washing.
[0039] Please see again Figure 4 In one embodiment of this application, the vortex generating mechanism 40 further includes two vortex nozzles 43. The vortex nozzles 43 are located below the fruit holding basket 20 and are cone-shaped, facing one side of the fruit holding basket 20. One vortex nozzle 43 can be connected to the side of the water inlet 41a away from the water inlet pipe 42 by heat fusion or bonding. In the washing tank 10b, the vortex nozzle 43 extends obliquely towards the side of the fruit holding basket 20. In this application, the cone-shaped vortex nozzle 43 can greatly increase the flow rate of the incoming water, so that the vortex flow rate is higher and the cleaning effect is better. The upwardly obliquely extending vortex nozzle 43 can not only form a rotating water flow in the horizontal direction, but also form a force in the vertical direction, causing the fruit to float upward. That is, through the combined action of horizontal rotation and vertical lifting, the movement of the fruit during the washing process is more complex, and the cleaning effect is further improved.
[0040] Please see again Figure 3 In this embodiment, the main body 21 and the side wall of the washing tank 10b form a flow-aiding gap 21c. This flow-aiding gap 21c is a certain distance between the outermost surface of the main body 21 and the side wall and bottom wall of the washing tank 10b. The flow-aiding gap 21c can prevent the fruit to be washed from being too close to the water inlet 41a, ensuring the formation of the vortex while preventing the water flow from impacting the surface of the fruit. On the other hand, it can allow the fruit to be washed to be more completely immersed in the vortex and fully contact the water flow, thereby further improving the washing effect.
[0041] In this embodiment, the cleaning brush 30 includes a fixed rod and multiple bristles connected to the surface of the fixed rod. To facilitate the disassembly, assembly, cleaning, and maintenance of the cleaning brush 30, a fixing rib 211 is protruding from the bottom of the main body 21. This fixing rib 211 extends in a ring shape, forming a circular fixing groove 21d. The diameter of the fixing groove 21d is slightly smaller than the diameter of the fixed rod. In practical applications, the lower end of the fixed rod can be pre-inserted into the fixing groove 21d to connect and fix the cleaning brush 30 and the fruit holding basket 20. Then, the fruit to be cleaned is placed in the holding groove 21a. After cleaning, the main body 21 is lifted out of the cleaning groove 10b using the assist handles 23 located on opposite sides of the main body 21. The cleaning brush 30 can then be disassembled, and the cleaned fruit can be removed.
[0042] In this embodiment, the fruit basket 20 also includes an elastic protective layer (not shown). The elastic protective layer is made of food-grade silicone or rubber. The elastic protective layer can be applied to the outer surface of the body 21 by bonding, hot pressing, or injection molding. By setting the elastic protective layer, the side wall of the holding groove 21a can be further prevented from damaging the surface of the fruit during the washing process.
[0043] Please see again Figure 3 In this application, the outer casing 10 also has a return water port 10d connected to the cleaning tank 10b. The return water port 10d is located above the two inlets 41a and is connected to the inlet of the vortex pump via a return water pipe 11. It is understood that the two inlets 41a continuously inject water into the cleaning tank 10b. As the water level rises, to prevent overflow, and to continuously generate vortices within the cleaning tank 10b, this application uses the return water port 10d and the return water pipe 11 to promptly discharge the water from the cleaning tank 10b. The discharged water can then be recycled back into the cleaning tank 10b via the inlet of the vortex pump.
[0044] In one embodiment of this application, the fruit washing machine 1 further includes a controller (not shown), a display screen 50, and control buttons 60. The controller is fixedly installed in the mounting cavity 10a with screws. The display screen 50 and control buttons 60 are mounted on the outer casing 10. The controller is communicatively connected to the vortex pump, the display screen 50, and the control buttons 60 via terminal connection cables. The display screen 50 can be used to display the working status of the fruit washing machine 1, and the control buttons 60 can be used to control the working mode of the fruit washing machine 1, such as the working time and power of the vortex pump, to achieve specific cleaning of the fruit. The controller, the display screen 50, and the control buttons 60, their control connection methods, and control logic are relatively mature existing technologies and will not be elaborated upon here.
[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
