Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cleaning machines for cleaning fruits and vegetables, and particularly relates to a cleaning basket structure for a cleaning machine and the cleaning machine. BACKGROUND

[0002] The current cleaning machine usually comprises a box body with a washing chamber, a spraying device arranged in the washing chamber, and a storage rack. The spraying device is used to draw water at the bottom of the box body into a water spraying component and spray it into the washing chamber to flush dishes or fruits and vegetables. The cleaning of fruits and vegetables by the fruit and vegetable cleaning machine is mainly realized by the turbulent flow in the fruit and vegetable tank. The size of the turbulent flow in the fruit and vegetable tank basically determines the cleaning degree of the fruits and vegetables. The generation of the turbulent flow mainly relies on the high-speed rotation of the blade to generate high-pressure water flow. The size of the water pressure in the spraying arm determines the strength of the turbulent flow.

[0003] The Chinese patent application for a cleaning basket and a cleaning machine applying the same, with the patent number CN202010898750.0 (application publication number CN114098571A), discloses a cleaning basket provided with a spraying arm, a first impeller, a first magnetic part, a second magnetic part, a generator, an AC / DC conversion module, and an electrolysis module. The cleaning basket is convenient to combine with a water tank to form a cleaning machine. When in use, the cleaning basket is placed in the water tank. The second magnetic part drives the first magnetic part, the spraying arm, and the first impeller to rotate. The water at the bottom of the cleaning basket is drawn into the spraying arm and further sprayed upward. In cooperation with the turbulent water flow, the cleaning effect is improved. However, the following defects exist:

[0004] 1. When the water flow is used for flushing, pesticide residues will remain on the surface of fruits and vegetables. The ordinary turbulent water flow is not thorough enough in removing pesticide residues.

[0005] 2. When cleaning fruits and vegetables, the upper side of the fruits and vegetables is easily not cleaned due to the shielding of the fruits and vegetables, which affects the customer's use experience.

[0006] 3. The spraying arm located in the cleaning basket occupies the internal space of the cleaning basket, reducing the accommodation of the objects to be cleaned.

[0007] Therefore, it is necessary to further improve the existing cleaning basket structure. SUMMARY

[0057] The present application will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[0058] As Figures 1 to 14 shown in the drawings, the cleaning machine of the present embodiment is a fruit and vegetable cleaning machine used for cleaning fruit and vegetable. The cleaning machine comprises a box body 6 and a cleaning basket structure, the box body 6 has a washing chamber 60 inside, and the cleaning basket structure is arranged in the washing chamber 60.

[0059] As Figures 1 to 14 shown in the drawings, the cleaning basket structure comprises a basket body 1, an impeller structure 2, a spraying member 3, a lower impeller 5, a handle 8, an upper spraying arm 9 and a lower spraying arm 4. As Figures 8 to 10 shown in the drawings, the basket body 1 has a cavity 10 with an open top, and the inner part of the bottom wall plate of the basket body 1 has a water inlet passage 12 for water inlet at a position adjacent to the center, and the diagonal lines of the bottom wall plate of the basket body 1 are two, which are a first diagonal line and a second diagonal line. The bottom wall plate of the basket body 1 is further provided with a first water delivery passage 13 located at the side of the water inlet passage 12 and connected with the water inlet passage 12, and along the water flow path, the cross-sectional area of the first water delivery passage 13 gradually decreases, thereby increasing the water flow speed and pressure in the first water delivery passage. In the present embodiment, the first water delivery passage 13 has four, two of which are arranged along the length direction of the first diagonal line and extend along the length direction of the first diagonal line, and the other two are arranged along the length direction of the second diagonal line and extend along the length direction of the second diagonal line, so that the four first water delivery passages form an X shape. Each of the first water delivery passages 13 is provided with a spraying member 3 adjacent to the center, which can rotate relative to the corresponding first water delivery passage 13, and the spraying member 3 is located on the outer bottom wall of the basket body 1. The structures of the spraying members are the same, and one of them will be described below.

[0060] As Figure 13 and Figure 14As shown, the spray part includes a central portion 30 located in the center and at least two sub-spray arms 31 arranged radially with the central portion 30 as the center. The interior of the central portion 30 has a water collection area 300 for water to enter, and the top wall plate of the central portion 30 has a water inlet channel 301 connecting the corresponding first water supply channel 13 and the water collection area 300. Along the fluid flow path, the water inlet channel 301 is located downstream of the first water supply channel 13. In this embodiment, there are three sub-spray arms 31. In addition, two or more sub-spray arms 31 having the same structure can be used. One of the sub-spray arms will be used as an example for explanation below. The interior of the sub-spray arm 31 has a flow channel 311 extending along its length and connected to the water collection area 300, and the top wall plate of the sub-spray arm 31 is provided with a spray hole 312. The spray hole 312 sprays upward to spray the object to be cleaned in the accommodating cavity 11. The water collecting area 300 and the flow channel 311 are connected to form a water flow cavity 3 a , and the water flow cavity 3 a is located downstream of the first water delivery channel 13 .

[0061] In addition, if Figure 14 As shown, each flow channel 311 is provided with a driving member for generating a rotational thrust in the water within the flow channel 311 to accelerate the rotation of the spray element 3. The driving member in this embodiment is an arcuate bar 32 extending along the direction of water flow. At least a portion of each arcuate bar 32 arches toward the direction of rotation of the spray element 3, thereby causing all arcuate bars 32 to rotate clockwise or counterclockwise as a whole, and the overall rotation of the arcuate bar 32 is opposite to that of the spray element 3. Specifically, the first end of the arcuate bar 32 is connected to the inner sidewall of the flow channel 311, and the second end of the arcuate bar 32 is connected to the end surface of the sub-spray arm 31 away from the water collection area 300. In this embodiment, the arcuate bar 32 separates the flow channel 311 into a first channel 3111 and a second channel 3112, which are not connected to each other. The arcuate bar 32 arches toward the second channel 3112, and both the spray hole 312 and the water collection area 300 are connected to the first channel 3111. Specifically, the first end of the curved strip 32 partially abuts against the first sidewall 3113 of the corresponding flow channel 311, adjacent to the water collection area 300. The sidewall of the flow channel 311 opposite the first sidewall 3113 is the second sidewall 3114. The second end of the curved strip 32 is connected to the second sidewall 3114 of the flow channel 311. The presence of the curved strip 32 creates a rotational thrust during the flow of water, ultimately ejecting water upward through the spray holes 312. This ensures that the spray element continuously sprays upward during rotation, providing targeted cleaning of the four corners of the basket. This also avoids the significant power loss associated with existing auxiliary spray arms, or sealing issues associated with locally installing spray arms in the trough. To prevent water accumulation in the flow channel from simultaneously flushing sediment below the sub-spray arm, the bottom wall of the sub-spray arm 31 is provided with an overflow port 313 connected to the first channel 3111 at a position corresponding to the first channel 3111.

[0062] As Figure 4 shown, the handle 8 has at least a part of it above the basket 1 and has a water flow channel 81 inside. The cross-sectional area of the water flow channel 81 gradually decreases along the water flow path. In the present embodiment, the handle 8 is in an inverted U-shape, and a first end of the handle 8 is connected to the first side plate la of the basket 1, and a second end of the handle 8 is connected to the second side plate lb of the basket 1 opposite to the first side plate la. In the present embodiment, the upper spraying arm 9 is below the handle 8, and the upper spraying arm 9 is rotatably arranged at a position adjacent to the center of the handle 8. Specifically, the top wall plate of the upper spraying arm 9 has a water inlet 911 adjacent to the center of the top wall plate, and the water inlet 911 is in communication with the water flow channel 81, and the periphery of the water inlet 911 is rotatably arranged at a position adjacent to the center of the handle 8. The upper spraying arm 9 has a water flow channel 91 inside, and the bottom wall plate of the upper spraying arm 9 has a plurality of downward spraying holes 912. The upper spraying arm 9 achieves the cleaning of the upper layer of the fruits and vegetables. In addition, the projection of the upper spraying arm 9 on the basket 1 along the vertical direction is located at a position adjacent to the center of the bottom wall plate of the basket 1, and the spraying area of the upper spraying arm 9 partially overlaps with the spraying area of the spraying member 3. In order to avoid the interference of the upper spraying arm 9 when the basket is pulled and cleaned, and to achieve the purpose of easy taking, the outer bottom wall of the handle 8 has a concave cavity 82 extending along the length direction of the handle 8 and concave upward, and the upper spraying arm 9 is located in the concave cavity 82. In addition, the strength of the handle is ensured.

[0063] As Figure 4 shown, the basket 1 has a second water supply channel 14 in fluid communication with the water flow channel 81, and the second water supply channel 14 is partially located on the bottom wall plate of the basket 1 and is located on the periphery of the water inlet channel 12 and is in communication with the water inlet channel 12. Along the fluid flow path, the first water supply channel 13 and the second water supply channel 14 are both located downstream of the water inlet channel 12. In the present embodiment, the second water supply channel 14 includes a horizontal channel 141 and a vertical channel 142, the horizontal channel 141 is located between two adjacent first water supply channels 13 and extends along the length direction of the horizontal bar portion of the handle 8, the first end of the horizontal channel 141 is in communication with the water inlet channel 12, the vertical channel 142 is located in the first side plate la of the basket 1, the lower end of the vertical channel 142 is in communication with the second end of the horizontal channel 141, and the upper end of the vertical channel 142 is in communication with the water flow channel 81. In this way, the water flow channel 81 is supplied with water.

[0064] As Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the lower spraying arm 4 is located in the washing chamber 60 and is arranged below the basket 1. The inner part of the lower spraying arm 4 is hollow to form a water collecting cavity 40. The bottom wall plate of the lower spraying arm 4 is provided with a water inlet 401 for water to enter the water collecting cavity 40. The top wall plate of the lower spraying arm 4 is provided with a through hole 41 which is in communication with the water collecting cavity 40 at the position corresponding to the opening. In addition, the top wall plate of the lower spraying arm 4 is provided with water spraying holes 403 for upward spraying. In the projection along the vertical direction, the spraying area of the lower spraying arm 4 partially overlaps the spraying area of the spraying member. In order to realize the installation of the lower spraying arm 4, the bottom wall plate of the cabinet 6 is recessed to form a recessed area 61 adjacent to the center. The recessed area 61 is provided with a fixing frame 62. The periphery of the water inlet 401 of the lower spraying arm 4 extends downward to form a ring wall 402 which is rotatably arranged on the fixing frame 62. The fixing frame 62 is provided with a water passing hole 621 for water to pass through. Along the fluid flow path, the water passing hole 621 is located upstream of the water inlet 401.

[0065] In order to improve the cleaning effect, as shown in Figure 6 , Figure 7 and Figure 10 , the basket 1 is provided with air passing channels 15. There is at least one air passing channel 15 between two adjacent first water passing channels 13. In this embodiment, there are multiple air passing channels 15 which are arranged along the circumference of the basket 1. In addition, as shown in Figure 8 , the air passing channel 15 is provided with at least one air outlet hole 153 for adding air to the water flow in the washing chamber 60. In this embodiment, each air passing channel 15 corresponds to one air outlet hole 153. Each air outlet hole 153 is located at the periphery of the spraying member 3. The structure of each air passing channel 15 is basically the same. Hereinafter, one of the air passing channels 15 will be taken as an example for description. The air passing channel 15 includes a first air passage 151 and a second air passage 152 along the air flow path. The first air passage 151 is located in the bottom wall plate of the basket 1 and is located above the first water passing channel 13. The second air passage 152 is located in the side wall plate of the basket 1. In order to reduce the water entering the second air passage 152, the second air passage 152 is n-shaped and includes a first sub-air passage 1521 and a second sub-air passage 1522 which are arranged vertically and a connecting air passage 1523 which is located between the first sub-air passage 1521 and the second sub-air passage 1522 and is in communication with the upper ends of the two.
