Current fruit and vegetable washing machines include spray-type and stirring-type. The spray-type sink-type fruit and vegetable washing machine washes fruits and vegetables through multiple nozzles arranged on the spray arm. Because the nozzles are fixed in direction, they cannot achieve the effect of washing fruits and vegetables in all directions. In addition, during the fruit and vegetable washing process, the spray water only washes the bottom of the fruits and vegetables, so the washing effect is poor.

[0003] The stirring fruit and vegetable washing machine uses an impeller to drive the water in the water tank to form a vortex and rotate in the water tank to drive the fruits and vegetables to be washed. However, the impeller of the existing stirring fruit and vegetable washing machine is fixed to the motor by screws, and the motor and the impeller are fixed in the water tank together, which is inconvenient to clean the water tank and the impeller. There is a cleaning dead angle at the impeller installation position, and the cleaning effect is poor. At the same time, when cleaning the impeller, there is a risk of the impeller accidentally starting and injuring people.

[0041] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 10 As shown, one embodiment of the present invention provides a fruit and vegetable washing machine, including: a water tank 1, a fruit and vegetable basket assembly 2 and a motor 11; the fruit and vegetable basket assembly 2 includes a basket body 21 and an impeller 22, the basket body 21 is installed in the water tank 1, and a receiving cavity 211 is formed in the basket body 21; the motor and the impeller 22 are both located outside the receiving cavity 211, and the motor 11 is detachably connected to the impeller 22 to drive the impeller 22 to rotate.

[0043] The motor 11 and the impeller 22 of the fruit and vegetable washing machine provided in this embodiment are both located outside the accommodating chamber 211. When in use, the motor 11 drives the impeller 22 to rotate, thereby driving the water in the water tank 1 to swirl and flow to wash the fruits and vegetables. When it is necessary to clean the impeller 22 or the water tank 1, since the impeller 22 and the motor 11 are detachably connected, the fruit and vegetable basket assembly 2 can be directly removed. At this time, the impeller 22 and the motor 11 are separated, and there is no spatial restriction of the water tank 1 around the impeller 22, so cleaning is more convenient. At the same time, after the fruit and vegetable basket assembly 2 is removed, only the output shaft of the motor 11 is left in the water tank 1. When cleaning the water tank 1, there is no dead corner for cleaning. The cleaning of the water tank 1 is more comprehensive and thorough, and the cleaning effect is better, which solves the problem of incomplete cleaning caused by the existence of a cleaning dead corner in the water tank 1 when the impeller 22 is installed in the traditional fruit and vegetable washing machine. In addition, when cleaning the impeller 22 , the impeller 22 is separated from the motor 11 , which can prevent the impeller 22 from rotating and stirring the rag or injuring people due to the motor 11 being started up by mistake, making the cleaning of the impeller 22 safer.

[0044] According to one embodiment of the present invention, Figures 1 to 10 As shown, the fruit and vegetable basket assembly 2 also includes a shaft cover 23, which includes a cover body 231 and a positioning shaft 232 connected to the cover body 231, the cover body 231 is located in the accommodating cavity 211 and connected to the basket body 21, the impeller 22 is provided with a through hole 221 corresponding to the positioning shaft 232, and the positioning shaft 232 passes through the bottom wall of the basket body 21 and the through hole 221.

[0045] In normal use, the positioning shaft 232 of the fruit and vegetable cleaning machine provided in this embodiment passes through the through hole 221 on the impeller 22, and the motor 11 is started to drive the impeller 22 to rotate, thereby driving the water in the water tank 1 to swirl and flow to clean the fruits and vegetables; when it is necessary to clean the impeller 22 or the water tank 1, since the impeller 22 and the motor 11 are detachably connected, the fruit and vegetable basket assembly 2 can be directly removed, the impeller 22 is rotated so that the positioning shaft 232 corresponds to the angle of the through hole 221, and the impeller 22 is removed for cleaning. 2 is not limited by the space of the water tank 1, so cleaning is more convenient, and it is ensured that the impeller 22 will not be scaled due to long-term inability to clean, thereby improving the cleaning effect and user experience; at the same time, after the fruit and vegetable basket assembly 2 is removed, only the output shaft of the motor 11 is left in the water tank 1, and there is no dead corner when cleaning the water tank 1, so the cleaning of the water tank 1 is more comprehensive and thorough, and the cleaning effect is better, which solves the problem of incomplete cleaning caused by the existence of a cleaning dead corner in the water tank 1 when the impeller 22 is installed in the traditional fruit and vegetable washing machine.

[0046] According to one embodiment of the present invention, Figures 8 to 10 As shown, the positioning shaft 232 includes a shaft body 2321 and a limit block 2322, and the limit block 2322 is connected to the shaft body 2321; the shape of the through hole 221 is adapted to the cross-sectional shape of the shaft body 2321 connected with the limit block 2322; the limit block 2322 cooperates with the bottom surface of the impeller 22 to prevent the shaft cover 23 and the impeller 22 from separating in the axial direction.

[0047] In this embodiment, the shape of the top projection of the shaft body 2321 and the limit block 2322 is the same as the shape of the through hole 221 on the impeller 22, and the size of the through hole 221 is equal to or slightly larger than the size of the top projection of the positioning shaft 232; in normal use, the impeller 22 is rotated to make the angles of the through hole 221 and the positioning shaft 232 correspond, at this time, the through hole 221 of the impeller 22 is aligned with the positioning shaft 232, the positioning shaft 232 passes through the through hole 221, and then the impeller 22 is rotated to make the angles of the through hole 221 and the positioning shaft 232 not correspond, at this time the limit block 23 22 forms a limit with the lower surface of the impeller 22 to prevent the impeller 22 from moving axially relative to the positioning shaft 232, that is, the impeller 22 is limited in the axial direction, and the positioning shaft 232 passes through the through hole 221 and is separated from the impeller 22; in addition, a receiving space is provided on the lower side of the impeller 22, and the positioning shaft 232 can pass through the through hole 221 to enter the receiving space, and when the impeller 22 rotates, the inner wall of the receiving space does not interfere with the positioning shaft 232; in this way, the connection between the impeller 22 and the basket body 21 can be realized, and the quick assembly and disassembly of the impeller 22 can be realized.

[0048] like Figures 8 to 10As shown, the limit block 2322 and the shaft body 2321 are both in the shape of round pins; there are two limit blocks 2322, which are respectively connected to the shaft body 2321 vertically, and the two limit blocks 2322 are symmetrically arranged about the shaft body 2321. When the symmetrically arranged limit blocks 2322 contact the bottom wall of the impeller 22 for limiting, the force is more reasonable; in the optional embodiment, the limit block 2322 can also be only one, or three, four, etc., and the shape of the limit block 2322 and the shaft body 2321 is not limited to the round pin shape, but can also be cylindrical, square tube, etc., which can also achieve the purpose of the present application.

[0049] like Figures 8 to 10 As shown, the axis of the through hole 221 is eccentrically arranged with respect to the axis of the impeller 22, that is, the through hole 221 is not arranged at the axis position of the impeller 22, and the impeller 22 and the positioning shaft 232 are eccentrically arranged, so that when the impeller 22 rotates, the positioning shaft 232 is driven to revolve around the axis of the impeller 22 as the center of the circle, and the impeller 22 and the basket body 21 are fixedly connected, so the rotation of the impeller 22 drives the basket body 21 to shake forward, backward, left and right through the positioning shaft 232, and the shaking of the basket body 21 causes the fruits and vegetables to roll continuously in the fruit and vegetable basket, thereby increasing the friction between the fruits and vegetables and the basket body 21, and improving the cleaning performance.

[0050] like Figures 8 to 10 As shown, a rivet column 2311 is provided on the cover body 231 of the shaft cover 23, and a rivet hole is provided on the bottom wall of the basket body 21. The shaft cover 23 is fixed to the basket body 21 by riveting the rivet column 2311 and the rivet hole; of course, in this embodiment, the cover body 231 can also be fixed to the bottom of the basket body 21 by screw connection, welding, etc.

[0051] like Figures 1 to 7 As shown, the motor 11 is detachably connected to the impeller 22 via the shaft sleeve 12; optionally, the shaft sleeve 12 is fixedly connected to the motor 11, and the impeller 22 is detachably connected to the shaft sleeve 12; wherein, the shaft sleeve 12 can be fixed to the end of the output shaft of the motor 11 by screws, and the shaft sleeve 12 is connected to the impeller 22 by plugging, snapping, etc., so as to realize the detachable connection between the impeller 22 and the motor 11. Furthermore, the shaft sleeve 12 and the impeller 22 are connected by plugging, so that when the impeller 22 or the sink 1 needs to be cleaned, the fruit and vegetable basket assembly 2 can be directly "pulled out" from the sink 1, which is more convenient to operate. Specifically, as Fig.10 As shown, a slot 222 is provided at the bottom of the impeller 22, and an insert block 121 is provided on the shaft sleeve 12. The length direction of the slot 222 is the same as the axial direction of the positioning shaft 232. In this way, when removing the fruit and vegetable basket assembly 2, the basket body 21 can be directly pulled upwards, and the disassembly and installation between the fruit and vegetable basket assembly 2 and the sink 1 is more convenient.

[0052] According to one embodiment of the present invention, Figures 5 to 7As shown, the bottom wall of the basket body 21 protrudes toward the accommodating chamber 211 to form a protrusion 212, and a mounting chamber 2121 is formed in the protrusion 212. The mounting chamber 2121 and the accommodating chamber 211 are located on both sides of the bottom wall of the basket body 21. The protrusion 212 is provided with a water outlet, which connects the accommodating chamber 211 and the mounting chamber 2121, and the impeller 22 is installed in the mounting chamber 2121. The impeller 22 is installed in the mounting chamber 2121 formed on the other side of the basket body 21, and the mounting chamber 2121 formed by the protrusion 212 is connected with the accommodating chamber 211 inside the basket body 21 through the water outlet. The water flow generated by the rotation of the impeller 22 is transmitted to the basket body 21 through the water outlet. The distance between the impeller 22 and the basket body 21 is reduced, which can increase the impact force of the water flow formed by the impeller 22, so that the water thrown out from the impeller 22 has a stronger cleaning effect on fruits and vegetables.

[0053] According to one embodiment of the present invention, Figures 1 to 3 As shown, the lower end surface of the impeller 22 is on the same horizontal line as the upper surface of the bottom wall of the basket body 21. On the one hand, the thrust of the impeller 22 stirring the water makes it difficult for fruits and vegetables to be adsorbed on the basket body 21, effectively solving the problem of fruit and vegetable adsorption during vortex cleaning; on the other hand, the height of the water thrown out by the impeller 22 is higher than the bottom wall of the basket body 21, so that the water flow can impact the four corners of the fruit and vegetable basket, and then the fruits and vegetables located in the corners of the basket body 21 can also be cleaned, increasing the cleaning area and improving the cleaning effect. In this embodiment, the lower end surface of the impeller 22 can also be higher than the upper surface of the bottom wall of the basket body 21, which can also achieve the purpose of improving the cleaning effect and solving the problem of fruit and vegetable adsorption during vortex cleaning.

[0054] like Figures 1 to 7 As shown, the fruit and vegetable washing machine also includes a motor bracket 15 and a shock-absorbing pad 16. The motor bracket 15 is connected to the bottom wall of the water tank 1 and is located at the lower side of the bottom wall of the water tank 1. The motor 11 is fixed on the motor bracket 15, and the shock-absorbing pad 16 is installed between the motor 11 and the motor bracket 15; the shaft sleeve 12 is fixed to the output shaft end of the motor 11; the motor 11 is supported by the motor bracket 15, and the vibration generated when the motor 11 rotates is reduced by arranging the shock-absorbing pad 16.

[0055] According to one embodiment of the present invention, Figures 1 to 7As shown, the fruit and vegetable washing machine also includes a water inlet mechanism 3, which includes a water inlet pipe 32, a flow meter 33, a connecting pipe 34, a water inlet gate valve and a water inlet assembly 31; a water inlet hole 14 is provided on the bottom wall of the water tank 1, and the water inlet assembly 31 is installed in the water inlet hole 14, and the water inlet assembly 31 is sleeved on the output shaft of the motor 11, and the water inlet assembly 31, the water inlet pipe 32, the flow meter 33, the connecting pipe 34 and the water inlet gate valve are connected in sequence. The water inlet gate valve is connected to the municipal water source, and the municipal water passes through the water inlet valve 35 to the connecting pipe 34, and enters the water tank 1 through the flow meter 33, the water inlet pipe 32 and the water inlet assembly 31. The flow meter 33 can monitor the water inflow in the water tank 1. When the water inflow reading of the flow meter 33 reaches a preset value (such as 2 liters, 3 liters, 4 liters, etc.), the water inlet valve 35 is closed, the motor 11 is started, and the impeller 22 is driven to rotate through the shaft sleeve 12. The energy is then transmitted to the basket body 21 through the shaft cover 23, so that the impeller 22 rotates and the basket body 21 shakes. After a predetermined cleaning time, the motor 11 stops working, and the mud and sand cleaning of fruits and vegetables is completed.

[0056] According to one embodiment of the present invention, Figures 1 to 7 As shown, the fruit and vegetable cleaning machine also includes a drainage mechanism 4; the drainage mechanism 4 includes a drainage port assembly, a drainage pipe 42 and a drainage pump 43; a drainage hole 13 is provided on the bottom wall of the water tank 1, the drainage port assembly is installed in the drainage hole 13, and the drainage port assembly, the drainage pipe 42 and the drainage pump 43 are connected in sequence, and a drainage filter 44 is also provided in the drainage port assembly 41. When the fruits and vegetables in the water tank 1 are cleaned, the drainage pump 43 is started, and the sewage in the water tank 1 is discharged through the drainage port assembly and the drainage pipe 42. Figure 1 and Figure 2 As shown, the fruit and vegetable washing machine further includes an upper cover plate 17. The water tank 1 is a structure with an upper end open. The upper cover plate 17 covers the open end of the water tank 1. When the fruit and vegetable washing machine is working, the upper cover plate 17 is closed to prevent water in the water tank 1 from splashing out. An overflow hole is provided on the water tank 1, and an overflow pipe 18 is connected to the overflow hole. The overflow pipe 18 is provided to prevent excessive water in the water tank 1 from overflowing from the upper end.
