Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and in particular to a fruit and vegetable washing machine and a washing method. Background Art

[0002] Existing dishwashers, fruit and vegetable washing machines, etc., are devices that spray cold or hot water onto dishes, fruits and vegetables to remove dirt adhering to the dishes, fruits and vegetables, and the dishes, fruits and vegetables, and usually include a pump and a nozzle for spraying washing water. Common dishwashers generally use a water pump to lift water and spray it onto the fruits and vegetables in the washing space to achieve the washing effect, or drive the washing basket to rotate and spray water from top to bottom into the washing basket to rinse the fruits and vegetables in the washing basket. Recently, there has also been a structure that uses turbulent water flow to wash fruits and vegetables soaked in water.

[0003] For example, the Chinese patent application "A spray arm and a cleaning machine using the spray arm" with application number CN201710714387.0 provides a structure that can make the water flow turbulent. The water flow turbulence in the fruit and vegetable tank of the dishwasher is mainly generated by the fixed spray hole jet of the fixed spray arm, which can produce a good turbulent effect in the local area. However, due to the limitation of the fixed position and direction of the nozzle, the water flow turbulence coverage area provided by the above structure is limited, and the water flow turbulence intensity in the fruit and vegetable basket is not enough, resulting in the inability to turn over large fruits and vegetables, resulting in a dead corner for cleaning, which affects the cleaning effect.

[0004] In addition, since the main functional components of the cleaning machine are concentrated at the bottom of the cleaning machine, pollutants such as fruit and vegetable debris and food residues mainly move with the flow, and are easily entangled or accumulated on structures such as the motor's transmission shaft, making them difficult to clean. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a fruit and vegetable washing machine which can increase the turbulence degree and turbulence range of water and thus improve the washing effect in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a fruit and vegetable washing machine which can avoid the accumulation of residues in the central part and is easy to clean, in view of the current status of the prior art.

[0007] The third technical problem to be solved by the present invention is to provide a cleaning method of the above-mentioned fruit and vegetable cleaning machine in view of the current status of the prior art.

[0008] The technical solution adopted by the present invention to solve at least one of the above technical problems is:

[0009] A fruit and vegetable washing machine comprises a box body with a washing chamber, a drainage port is provided on the bottom wall of the box body, a drainage assembly connected to the drainage port is provided under the box body, and further comprises:

[0012] The present invention utilizes the water from the first water inlet and the second water inlet to form a large turbulent circulation in the outer part of the washing chamber, and the impeller can form a small turbulent circulation in the central part of the washing chamber. The double circulation combination can not only increase the turbulence degree of water, but also increase the turbulence range, which is beneficial to improving the cleaning effect. During the cleaning process, since the impeller forms turbulence in the central part, small-volume objects to be cleaned can keep moving with the water flow, and residues can be discharged in time with the return water process, which is beneficial to further improve the cleaning effect of small-volume objects, avoid residue accumulation, and improve the cleaning effect.

[0013] Preferably, the first water inlet and the second water inlet are arranged diagonally in the box, and the water flow input into the box through the first water inlet and the second water inlet forms a first circumferential circulation turbulence located at the outer part of the washing chamber in the box, and the impeller forms a second circumferential circulation turbulence located at the central part of the washing chamber. The above scheme is adopted to form a double circulation coordinated turbulence, which can not only increase the turbulence degree of water, but also increase the turbulence range, which is conducive to improving the cleaning effect.

[0014] Preferably, the bottom of the impeller is rotatably supported in the middle of the drain outlet, and the first circumferential circulating turbulence provides power for the initial rotation of the impeller. The above structure facilitates the non-active power rotation of the impeller.

Preferably, the impeller includes a disc-shaped substrate, and the upper surface of the substrate is provided with a second blade extending in a circumferential spiral from the center to the edge, and the first circumferential turbulence acts on the second blade to drive the impeller to rotate. The first circumferential circulating turbulence provides power for the impeller in a wide range of circumferences, and the first blade drives the impeller to rotate at the center of the washing chamber. The combination of the two sets of power can improve the stability of the impeller rotation.

[0016] Preferably, a shaft extending downward is provided in the center of the lower surface of the substrate, and the first blades are multiple and extend spirally from the outer surface of the shaft to the edge of the substrate. Preferably, the bottom wall of the box body is partially concave to form a sinking area arranged around the drain outlet, the diameter of the impeller base plate is larger than the diameter of the sinking area, the height of the first blade gradually decreases from the center of the base plate to the edge of the base plate, and the lower edge of the first blade gradually tilts upward from the center of the base plate to the edge of the base plate, the lower end of the shaft is supported at the drain outlet in the center of the sinking area, the outer end portion of the first blade is arranged close to the inner bottom wall of the box body outside the sinking area, and the inner end portion of the first blade extends downward into the sinking area. With the above structure, the base plate, two adjacent first blades, and the bottom wall of the washing chamber jointly enclose a return water channel, which is conducive to combing and guiding the falling water, and the residue is sucked into the residue collection basket in the sinking area through the return water channel, which is conducive to playing a stabilizing role and improving the rotation stability of the impeller and the residue collection effect.

[0017] In order to facilitate installation, a support arm is provided in the drain port, a support ring is provided in the center of the support arm, and an annular groove arranged along the circumferential direction and capable of rotatably cooperating with the support ring is provided on the outer surface of the shaft.

[0018] In the present invention, a drainage cavity connected to the drainage port is provided at the bottom of the box body, the first side wall of the drainage cavity is connected to the drainage assembly near the bottom, and the second side wall of the drainage cavity is connected to the water pump mechanism through a pipeline. A slag collecting basket sunk into the drainage cavity is provided at the drainage port to accumulate residues. After cleaning, the impeller can be removed, and then the slag collecting basket can be taken out for cleaning.

[0019] Preferably, the water pump mechanism includes a pump casing, an impeller, and a motor. The pump casing is disc-shaped and has a pump cavity. The pump cavity is provided with a partition that can separate it into an upper cavity and a lower cavity. The impeller is rotatably arranged in the upper cavity. The motor is arranged at the bottom of the pump casing and the output shaft passes through the bottom wall of the pump casing and the partition from bottom to top and extends into the upper cavity to connect with the impeller. The drain port is connected to the lower cavity, and the first water outlet and the second water outlet are spaced apart and arranged on the side of the upper cavity. The above structure is adopted to separate the water suction area and the drainage area of ​​the water pump mechanism, which is conducive to improving the stability of the water pump and improving the water pumping effect.

[0021] A cleaning method of a fruit and vegetable cleaning machine, using the above-mentioned fruit and vegetable cleaning machine, the process is as follows:

[0022] (1) Inject washing water into the washing chamber. After the water injection is completed, the drainage component closes the drainage pipeline, and the water pump mechanism is connected to the drainage port;

[0023] (2) When the objects to be washed are small-volume fruits and vegetables, the water flow input into the box body through the first water inlet and the second water inlet forms a first circumferential circulating turbulent flow located at the outer part of the washing chamber in the box body. The first circumferential circulating turbulent flow drives the impeller to start rotating. The impeller is further driven by the falling water to form a second circumferential circulating turbulent flow located in the central part of the washing chamber. The inner and outer turbulent flows jointly wash the fruits and vegetables. The first circumferential circulating turbulent flow drives the fruits and vegetables to circulate and wash in a large range, and the second circumferential circulating turbulent flow causes the fruits and vegetables to accumulate locally on the wall in a small range in the central part of the washing chamber.

[0024] When the objects to be washed are large-volume fruits and vegetables, the impeller is removed, and the water flows input into the box body through the first water inlet and the second water inlet form a first circumferential circulation turbulence located at the outer part of the washing chamber in the box body. The first circumferential circulation turbulence drives the fruits and vegetables to circulate and wash in a large range, and the generated fine residues gather in the center of the washing chamber without circulating with the fruits and vegetables.

[0025] (3) After washing is completed, the drainage component opens the drainage channel to pump the washing waste water into the sewer pipe.

[0026] Compared with the prior art, the advantages of the present invention are: the present invention utilizes the water from the first water inlet and the second water inlet to form a large turbulent circulation in the outer part of the washing chamber, and the impeller can form a small turbulent circulation in the central part of the washing chamber. The double circulation combination can not only increase the degree of turbulence of the water, but also increase the range of turbulence, which is beneficial to improving the cleaning effect; during the cleaning process, since the impeller forms turbulence in the central part, small-volume objects to be cleaned can keep moving with the water flow, and residues can be discharged in time with the return water process, which is beneficial to further improve the cleaning effect of small-volume items, avoid residue accumulation, and improve the cleaning effect.

[0034] The present invention is further described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 7 As shown, the fruit and vegetable washing machine of this embodiment includes a box body 1 with a washing chamber 11 , a drainage port 12 is formed on the bottom wall of the box body 1 , and a drainage assembly 2 connected to the drainage port 12 is disposed under the box body 1 .

[0036] The fruit and vegetable cleaning machine of this embodiment further includes a water pumping mechanism 3 and a pulsator 4. The water inlet 33 of the water pumping mechanism 3 is connected to the drain 12. The water pumping mechanism 3 is provided with a first water outlet 31 and a second water outlet 32. The first side wall of the housing 1 is provided with a first water inlet 101 arranged near the rear side thereof, and the second side wall arranged opposite to the first side wall is provided with a second water inlet 102 arranged near the front side thereof. The first water inlet 101 and the second water inlet 102 are both multiple and arranged at intervals along the vertical direction of the housing 1. The first water outlet 31 of the water pumping mechanism 3 is connected to the first water inlet 101 of the housing 1 through a water guide pipe, and the second water outlet 32 ​​of the water pumping mechanism 3 is connected to the second water inlet 102 of the housing 1 through a water guide pipe. The pulsator 4 is rotatably and detachably provided at the drain 12.

[0037] In this embodiment, the water entering from the first water inlet 101 and the second water inlet 102 can form a large turbulent circulation in the outer part of the washing chamber 11, and the impeller 4 can form a small turbulent circulation in the central part of the washing chamber 11. The combination of the double circulations can not only increase the degree of turbulence of the water, but also increase the range of turbulence, which is beneficial to improving the cleaning effect. During the cleaning process, since the impeller 4 forms turbulence in the central part, small-volume objects to be cleaned can keep moving with the water flow, and residues can be discharged in time with the return water process, which is beneficial to further improve the cleaning effect of small-volume items, avoid residue accumulation, and improve the cleaning effect.

[0038] The first water inlet 101 and the second water inlet 102 are arranged diagonally in the housing 1, and the water flow input through the first water inlet 101 and the second water inlet 102 forms a first circumferential circulation turbulent flow 01 located at the outer part of the washing chamber 11 in the housing 1, and the impeller 4 forms a second circumferential circulation turbulent flow 02 located at the central part of the washing chamber 11. The above scheme is adopted to form a double circulation coordinated turbulent flow, which can not only increase the turbulence degree of water, but also increase the turbulence range, which is conducive to improving the cleaning effect.

[0039] The bottom of the impeller 4 is rotatably supported in the middle of the drain port 12, and the first circumferential circulating turbulence 01 provides power for the initial rotation of the impeller 4. The above structure facilitates the rotation of the impeller 4 without active power.

[0040] The lower part of the impeller 4 is provided with a first blade 41 which can drive the impeller 4 to rotate under the action of falling water. The direction in which the first blade 41 drives the impeller 4 to rotate is consistent with the direction of the first circumferential circulating turbulent flow 01. The first circumferential circulating turbulent flow 01 provides auxiliary power for the rotation of the impeller 4. The impeller 4 includes a disc-shaped substrate 43. The upper surface of the substrate 43 is provided with a second blade 42 extending in a circumferential spiral from the center to the edge. The first circumferential turbulent flow acts on the second blade 42 to drive the impeller 4 to rotate. The first circumferential circulating turbulent flow 01 provides power for the impeller 4 in a wide range of circumferential directions. The first blade 41 drives the impeller 4 to rotate at the center of the washing chamber 11. The combination of the two groups of power can improve the stability of the rotation of the impeller 4.

[0041] A shaft 44 extending downward is provided at the center of the lower surface of the base plate 43, and the first blades 41 are multiple and extend spirally from the outer surface of the shaft 44 to the edge of the base plate 43. The bottom wall of the housing 1 is partially concave to form a sinking area 13 arranged around the drain port 12. The diameter of the base plate 43 of the impeller 4 is larger than the diameter of the sinking area 13. The height of the first blade 41 gradually decreases from the center of the base plate 43 to the edge of the base plate 43, and the lower edge of the first blade 41 gradually tilts upward from the center of the base plate 43 to the edge of the base plate 43. The lower end of the shaft 44 is supported at the drain port 12 in the center of the sinking area 13. The outer end portion of the first blade 41 is arranged close to the inner bottom wall of the housing 1 outside the sinking area 13, and the inner end portion of the first blade 41 extends downward into the sinking area 13. With the above structure, the base plate 43, the two adjacent first blades 41, and the bottom wall of the washing chamber 11 together enclose a return water channel. This structure is conducive to combing and guiding the falling water. The residue is sucked into the residue collecting basket in the sinking area 13 through the return water channel, which is conducive to stabilizing the flow and improving the rotation stability of the impeller 4 and the residue collecting effect.

[0042] For ease of installation, a cross-shaped support arm 121 is provided in the drain port 12 , a support ring 122 is provided in the center of the support arm 121 , and an annular groove 45 arranged circumferentially and rotatably matched with the support ring 122 is provided on the outer surface of the shaft 44 .

[0043] In the present invention, a drainage cavity 14 connected to the drainage port 12 is provided at the bottom of the box body 1, and the first side wall of the drainage cavity 14 is connected to the drainage assembly 2 near the bottom, and the second side wall of the drainage cavity 14 is connected to the water pump mechanism 3 through a pipeline. A slag collection basket (not shown in the figure) sunk into the drainage cavity 14 is provided at the drainage port 12 to accumulate residues. After cleaning, the impeller 4 can be removed, and then the slag collection basket can be taken out for cleaning.

[0044] The pump mechanism 3 includes a pump housing 34, an impeller 35, and a motor 36. The pump housing 34 is disc-shaped and has a pump cavity 340. A partition 341 is provided in the pump cavity to separate it into an upper cavity and a lower cavity. The partition 341 has an opening in the middle. The impeller 35 is rotatably arranged in the upper cavity. The motor 36 is arranged at the bottom of the pump housing 34, and the output shaft 44 passes through the bottom wall of the pump housing 34 and the partition from bottom to top and extends into the upper cavity to connect with the impeller 35. The drain port 12 is connected to the lower cavity. The first water outlet 31 and the second water outlet 32 ​​are arranged at intervals on the side of the upper cavity. The above structure is used to separate the water suction area and the drainage area of ​​the pump mechanism 3, which is conducive to improving the stability of the pump and improving the pump effect.

[0045] A water inlet is also provided on the side wall of the box body 1 , and a water inlet valve 16 connected to the water inlet 15 is provided outside the box body 1 .

[0046] The cleaning method of the fruit and vegetable cleaning machine in this embodiment is:

[0047] (1) Washing water is injected into the washing chamber 11. After the water injection is completed, the drainage assembly 2 closes the drainage pipeline, and the water pump mechanism 3 is connected to the drainage port 12;

[0048] (2) When the objects to be washed are small-volume fruits and vegetables, the water flow input into the housing 1 by the first water inlet 101 and the second water inlet 102 forms a first circumferential circulating turbulent flow 01 located at the outer part of the washing chamber 11 in the housing 1. The first circumferential circulating turbulent flow 01 drives the impeller 4 to start rotating. The impeller 4 is further driven by the falling water to form a second circumferential circulating turbulent flow 02 located at the central part of the washing chamber 11. The inner and outer turbulent flows wash the fruits and vegetables together. The first circumferential circulating turbulent flow 01 drives the fruits and vegetables to circulate and wash in a large range, and the second circumferential circulating turbulent flow 02 locally accumulates the fruits and vegetables on the wall in a small range in the central part of the washing chamber 11.

[0049] When the objects to be washed are large-volume fruits and vegetables, the impeller 4 is removed, and the water flow input from the first water inlet 101 and the second water inlet 102 into the housing 1 forms a first circumferential circulation turbulent flow 01 located at the outer portion of the washing chamber 11 in the housing 1. The first circumferential circulation turbulent flow 01 drives the fruits and vegetables to circulate and wash in a large range, and the generated fine residues gather in the center of the washing chamber 11 without circulating with the fruits and vegetables.

[0050] (3) After washing is completed, the drainage component 2 opens the drainage channel to pump the washing waste water into the sewer pipe.

[0051] In this embodiment, the use of the impeller can be selected according to the different volumes to be cleaned, thereby forming a specific turbulent form to improve the cleaning effect.
