[0116] Leave proper clearance 4 between the inner wall of the washing basket 3 and the washing-bucket 5, the up cover 1 of the washing-bucket 5 is hinged with the body through the hinge axis 1-5, to achieve the lid's opening and closing through the rotation of the hinge axis, to achieve that the bucket closes the cover by spring deduction 1-6, around the lid sets a waterproof sealing tape. Above the lid sets a gearbox for gear motor assembly 1-3 to hold the gear motor, output shaft 1-4 of the gear motor goes through the cover of the underside of the lid and the head inserts into the central filter sleeve 2-1 of basket's opening, shaft and sleeve are connected with spline lenient 2-2. Shaft 1-4 drive sleeve 2-1 to rotate so as to drive the filter at the mouth of the basket.

[0117] In the cavity of the body shell 6, the underpart cavity is set with water inlet 9 and the inlet valve assembly 9-1, and the inlet communicates with the washing-bucket, so that water can automatically draw into the washing-bucket 5 under the control of the controller. There is water level controller to monitor water level in the cavity (for simplicity, not shown in the picture).

[0118] In the cavity of the body shell 6, the underpart cavity is set with drain 10 and the drain valve assembly 10-1, and the drain is connected with central bottom of the washing-bucket, or quasi-center. In this case the lower part of the washing-bucket is funnel-shaped, and the center is the lowest, so it can form effects of -powerful vortex sewage.

[0119] The upper part of the front of fuselage has an operation panel 23, in which there is corresponding controller 22. By operating the control panel buttons, to achieve the operation of the controller. The controller can automatically control water inlet and drainage and the cleaning procedures.

[0120] See FIG. 2 and FIG. 3, in order to be more conducive for understanding the embodiment, FIG. 2 provides the assembly diagrammatic drawing of the first embodiment of the present invention, FIG. 3 is the label of all parts in FIG. 2 (for simplicity, parts of this specification schematic sectional drawing show not symbols).

[0121] FIG. 4 is the schematic of the washing-bucket and chassis of the first embodiment of the present invention, that is the schematic that the filter in the basket's opening and the washing-basket and filter under the basket and tray assembly have not been installed, and in the figure the snap hook 1-6 of the lid and the bucket body does not catch live, so the lid bounce a certain angle due to the action of the spring hinge axis 1-5.

[0122] See FIG. 5 and FIG. 6, in order to be more conducive for understanding the embodiment, FIG. 5 provides the schematic drawing of the combinations of the filter under the basket and the multifunctional tray of the first embodiment of the present invention. FIG. 6 is a schematic drawing that FIG. 5 is installed in FIG. 4 (for simplicity, the filter mesh under the basket are not shown).

[0123] See FIG. 7 and FIG. 8, FIG. 7 is a cross-sectional schematic view of the filter in the basket's inlet of the first embodiment of the present invention, and in the drawing the aperture of the filter screen is not painted in proportion, but as a hint, and the filter screen of the basket's inlet in the other figures of the first embodiment are not shown in addition to FIG. 7, FIG. 8 is a stereoscopic schematic view of the filter in the basket's inlet of the first embodiment of the present invention.

[0124] When working, put fruits and vegetables into the basket, and put latch 2-3 of the filter of the basket inlet insert into the jack 3-2 of washing-basket inlet to make filter 2 of basket inlet cover the basket inlet. Then cover with the lid, at the same time, slow down the motor's output shaft 1-4 can be easily inserted the sleeve 2-1. Then open the inlet valve, under the control of the water level controller draw water to a predetermined level and close the backward valve. Then the motor starts, at the same time the output shaft 1-4 of the gear motor rotates drive sleeve 2-1 to rotate through the loose big gap splines 2-2 so as to drive the filter of the basket inlet 2 to rotate. Because latch 2-3 of the filter of the basket inlet insert down to the jack 3-2 of washing-basket inlet to drive the whole washing-basket to rotate. And because the head-neck shaped bolt 7-3 on the tray assembly 7 holes up into the pin hole associated with it in the bottom of the washing-basket so that the washing-basket drive the tray to rotate. Because the tray has the downward extending shaft 7-2, the shaft can be synchronized with the rotation of the housing in the circumferential direction, so that the two pieces of water repellent sheet that are fixed to the shaft's end rotate synchronous and repellent the water; and because the shaft 7-2 and the central tube bearing 8-1 of the filter under the basket are interference fit, the shaft is fixed with the bearing 81 in the axial direction, while the filter under the basket is fixed by the screw 8-3 to the bucket body, therefore in the axial direction, the tray is fixed to the bucket body, and also play a supporting role to the washing-basket.

[0125] With the rapid rotation of the washing-basket, fruits and vegetables in the basket as well as the water do the centrifugal movement, and fruits and vegetables move to the basket's side and was blocked by the basket's walls and stay near the side wall, while the water flow is flung by the centrifugal forces from the washing-basket to the gap 4 of basket and bucket, then rise to the top of the basket, then water is drawn out with Group B impurities and Group C impurities, and part of Group B impurities sink to the end of the bucket, and the rest Group B impurities and Group C impurities that are thrown together with the rising water flow, rises to the above of the basket, and are hampered by the top lid or the erected retaining ring above the bucket and down to the center of the filter mesh in the basket's mouth, and these impurities cannot pass through the dense mesh and retained in the filter mesh in the basket's mouth, to complete Y operation. While the water flow passes through the filter strainer of the basket ports and continue to fall into the basket, and then, be flung to the gap of washing-basket and washing-bucket by the centrifugal force again, like this cycling flow, each cycle of every stream of water goes through the gap of the vegetables in washing-basket, to form rapidly relative motion with the surface of the fruit and vegetable, and form friction, with the surface of fruits and vegetables, produce friction to impurities and vegetable spin off to complete the X operation. The most crucial point is that each cycle of every water flow takes Group B impurities and Group C impurities mixed up with vegetables out of the washing-basket, and into the filter of basket's mouth. Then, these Group B impurities and Group C impurities stay in the filter of basket's mouth. That is to say, these impurities leave the basket and cannot comeback into the basket, never return, they will be no return to the vegetables if leave the vegetables. In this example set the vegetable washer's basket 200 revolutions per minute, a program of rotating with 20 minutes, about 4000 rpm, even if every turn brings a little bit of impurities (Note: no return impurities, there will not fall back into the basket if impurities come up), a little bit in 4000, it is not possible without cleaning up the impurities. Impurities in washing-basket is reducing every second, this second are less than last second, the next second are less than this second, and all gradually lien to the filter of the basket's mouth. The water flow not only plays the role of water erosion, but also plays the role of scouring, while by the vegetable washer of existing technology, water only plays the role of scouring.

[0126] While in the vegetable washer of existing technology, because there is no filter at the mouth of the washing-basket, impurities are thrown from the basket's side, up to the basket's opening, and spray down to the basket from the basket's opening, no matter how many times water cycle up and down and inside and outside, these Group C impurities and part of Group B impurities also cycle so many times along with the water cycling. Water in washing-bucket is discharged, Group C impurities and part of Group B impurities are still mixed in the vegetables, especially worse to the situation of leafy. Therefore, in video advertising of vegetable washer in the existing technology, we have never met that people take these vegetables such as leek garden chrysanthemum amaranth watercress with much more impurities for examples to wash, and often see them take apples peach lettuce and other ingredients that are easy to clean.

[0127] The filter of the basket inlet has the function of blocking impurities to backflow and storing up impurities, so it is also known as impurities blocker, or contaminant retention device.

[0128] In this embodiment, the control panel 23 is slated to have many time plans and speed options available to suit the needs of different user's preferences and different fruits'and vegetables'needs. Scheme in this case is set for a total of 24 minutes through the wash process, four times running. Each time the water inflow takes one minute and then rotating washing takes 3 minutes and then begin to open the drain valve while rotating water drain for about one minute to complete the washing one time. The whole process carries on a total of four times in the waterwashdrainage. In four minutes of the rotating washing it can cross clockwise rotation and counterclockwise rotation.

[0129] Now discuss the feature of the sixth minute work in this case: use the method of cleaning of the vortex center to remove the sewage water and impurities. The controller opens the drain valve according to the set procedures, then washing-basket continues to rotate in a clockwise direction, the flow continues to rotate in a clockwise direction, and the water forms vortex in the center of the bucket spinning flowing out of the washing-basket and is discharged out of the washing-bucket by the drain. Since the drain 10's opening in the bottom center of the washing-bucket 5, then the rotational speed of the water near the mouth of the drain is quite quick, and quickly roll Group B impurities which are deposited in the funnel-shaped bottom of the bucket into the drain, and water continue to rotate after going into the drain due to inertia will, rotating and going forward, which acts like a bullet having a rifle movement inside the barrel, can remove Group C impurities more thoroughly to the outside world, and eliminate sand accumulated nearby rubber plug in the drain valve to avoid leakage.

[0130] Also, before the drain valve open, there are parts of heavy Group B impurities, when rotating to the drain's opening at the center bottom of the bucket, having dropped to the drain to wait for the discharge, that is to say, the drain provides indwelling space for Group B impurities and becomes indwelling devices of Group B impurities. In this way, when the washing-basket is rotating and working, Group B impurities in washing-basket is reducing every second, this second are less than last second, the next second are less than this second. While the vegetable washer in

existing technology, because there is no opening in the bottom center of the bucket, most of Group B impurities (except parts with water rising and cycling) accumulate center around axis 102 in the bottom.

[0131] The vegetable washer of existing technology, since in the central bottom of the bucket sets the rotation axis, the drain's opening can only be set at the edge of the bottom of the washing-bucket, and it fails to achieve this effect, see FIG. 22 and FIG. 23. There exist four defects in this bucket-bottom structure of the existing technology: First, because of the water's rotation large number of Group B impurities accumulate in the central area of the bucket's bottom (near the axis of FIG. 22 or near the shaft seat of FIG. 23), these impurities cannot be discharged from the drain provided in the drain edge of the bucket's bottom. Second, the sand particles longterm accumulating in the vicinity of the axis are likely to be involved in the gap of shaft and waterproof cup, causes cup scratches and scratches causes sealing leakage. Third, the hydrodynamic characteristics of the sewage flowing to the center outlet while rotating cannot be used to take away the impurities, particularly Group B impurities. Fourth, water flow cannot be discharged by rifled type moving after going into the drain pipe, to the accumulation of sand flowing through the drain valve when in the vicinity of the rubber plug in the drain valve, which easily lead to a rubber stopper loose relationship, leading to water leakage.

[0132] As we all know, the cross-section of the washing-bucket's chamber of the vegetable washer and that of the washing-basket are a pair of concentric circles, so the shaft of the washing-basket of course goes through the center of this pair of concentric circles. Therefore in the central bottom of the vegetable washer of existing technology there sets the rotating shaft go through upward (see FIG. 22) or set shaft seat at the center bottom of the bucket (see FIG. 23) is also a matter of course, nothing wrong; this setting is an inevitable association of a staff in this technology. And the innovative thinking and creative work of the present invention lies in the irrational setup program that abandons the conventional. Open the outlet in the bottom center of the bucket filled with water, and the sewage effect has been improved essentially. Coupled with the bottom of the bucket made as funnel-shaped, sewage is very thorough.

[0133] Now discuss the operating characteristics of sixth minute to eighth minute in this case: the fruits and vegetables make periodic heart movement and centrifugal movement, in order to achieve the placement angle of flipping and flapping fruits and vegetables in the basket. The sixth minute, the controller opens the drain valve according to the set procedures, then washing-basket continues to rotate in a clockwise direction, and the water flow continues to rotate in a clockwise direction, due to the opening of drain 10 opens in the center bottom of the washing-bucket 5, the water rotates to the center from all around, and form vortex in the center of the bucket spinning out of the washing-bucket and discharge outside by the drain. The water flow also drives fruits and vegetables to move towards the center of the basket (including scrolling and flipping). Until the water is drained, close the drain valve. Fruits and vegetables changes from the relatively concentrating remain near side walls in the washing-basket to relatively concentrating remain near the center in the washing-basket. The seventh minute, according to set procedures the inlet valve opens the second time, penetrating water under the control of the water level controller to a predetermined level and then backward valve is closed. Next the eighth minute, motor starts, then output shaft 1-4 of gear motor rotates and goes through splines 2-2 of a large loose gap driving sleeve 2-1 to rotate so as to drive the filter 2 of the basket's inlet to rotate. Because latch 2-3 of the filter of the basket inlet insert down to the jack 3-2 of washing-basket inlet to drive the whole washing-basket to rotate. Thereby drive water repellent plate 7-1 rotates together to repellent, thereby drive the whole bucket of water in the washing-bucket to rotate together. With the rapid rotation of the washing-basket, fruits and vegetables in the basket as well as the water do the centrifugal movement, and fruits and vegetables move to the basket's side and was blocked by the basket's walls and stay near the side wall, and back to the position before the original drainage. The same of the process of centrifugal movement and the process of the concentric movement is the process of fruits and vegetables sufficiently rolling and turning, to achieve the effect of replacing manual turning fruits and vegetables in the water .Like this every time water is changed, each vegetable is placed to another angle and changed to another face as the face of the water. And this flip is done every time after we change water, and is unlike the violence when washing clothes in the washing, so it will not cause harm to fruits and vegetables.

[0134] The stated output shaft 1-4 and sleeve 2-1 use a large loose gap key, for example, only four or three teeth, etc. are for convenience when you put the lid the shaft 1-4 can be easily inserted into sleeve 2-1, as long as achieving this purpose and can play a driving role, it can be OK in any other conventional mechanical solutions. For example gear transmission cross shaft surface can be all right in the field of mechanical.

[0135] Whether the stated washing process to be introduced into the ozone or not , there are two options for users to choose on the control panel 23. If desired, may according to the program automatically inlet ozone into the washing-bucket 5 by the ozone generator 11 within a predetermined time. Discharge excess ozone residue through the filter chamber 1-1.

[0136] Left the proper clearance 4 between the inner wall of the washing-basket and washing-bucket as water flow's rising channel. Now that it is the channel, the diameter is the same as a water pipe, and the width of the channel can only be determined based on the desired flow rate and flow speed which are affected by the size of the bucket and speed of the washing-basket's rotation. Therefore, it cannot have a uniform value, such as a same number, is not the best choice of two washing-buckets of a small diameter and a big diameter. But by the logic of the relevant amounts described in this paragraph, we can calculate the value for the optimum gap to specific examples step by step through the experimental.

[0149] FIG. 21 is the cycling diagram of the always mixing of water flow and the Group B impurities all along in the vegetable washer in existing technology.

[0150] If allowing the instructions attached figures using photographs, I can provide the material photographs of FIG. 22, FIG. 23, FIG. 24 and FIG. 26.

[0151] According to the components of the above examples make simple recombination to produce new implementations, all of which belong to the scope of patent protection of the same transformation. And because many common parts and well known transmission mechanism in the field of mechanical can be replaced with each other to achieve the same purpose, any of the embodiment converted out are within the scope of patent protection of the same transformation.

[0152] Now demonstrate that the vegetable washer depends mainly on the water flow spraying vegetables is a technology bias. As we all know, all the vegetable washers in the existing technology stress washing vegetables by spraying, called spray technology, which emphasizes water returns from above and fells off in the washing-basket, and felling off in the washing-basket plays important role in washing vegetables, This can be seen from television advertising of the vegetable washer of the various manufacturers, sales page of selling vegetable washer online. But in fact, this is a technology bias. This technology bias guides people try to open the mouth of the basket, and cannot have the cover so as not to slow down the falling speed of the water flow and affect the placement of water, while the present invention is on the contrary, and filter is located in the basket's inlet, and in the dense filter accumulated a great deal of Group C impurities and some Group B impurities, objectively slowing down the flow rate and affecting the placement of water which is random and irregular. But the washing effect improved significantly. That proves that when water drops the so-called spray does not play a key role in washing vegetables, that is, phenomenon of water spraying does exist, but just a kind of water cycling phenomenon of dynamic vegetable washer.

[0153] Experiments show that regardless of the placement of the water in the center of the basket or around the basket that is the top of the vegetables (note: vegetables stay surrounding the basket), the washing effect is due to the friction of the gap when water goes through vegetables, rather than the sprinkling of water falling. Because fruits and vegetables are staying within the containment of water from the beginning to the end, and the falling water cannot catch in fruits and vegetables no matter where the whereabouts is. The swimmer can realize this principle most: when a man is swimming in the pool it suddenly rains heavily, his head and shoulders exposed on the surface can feel the rain, but below the surface portions such as loins and legs do not feel the rain, when his body was submerged, then no matter how heavy rain is his body cannot got caught.

[0154] Since water's placement has no effect on cleanliness of washing vegetables, the shape of the backwater plate (or called rib flap retaining bar curb retaining piece, etc.) is not important, and can be stand sheet of various shapes.
