Abstract

A method for washing vegetables includes such steps as putting fruit or vegetable in washing basket, and rotating the basket by motor to force the water to flow cyclically and reciprocally for separating impurities from vegetables. The method is characterized by simultaneously having the following three technical characteristics of A, B and C, or having at least one of the following three technical characteristics of ABC. The characteristic A is that the impurity thrown to the outside of the washing basket together with water is prevented from circularly falling back into the basket together with water to gradually purify the vegetables in the basket, the characteristic B is that the sewage and the impurity are removed by adopting a vortex center sewage discharge method, and the characteristic C is that the placing angle of the fruits and vegetables in the basket is turned and overturned by adopting a method of forcing the fruits and vegetables to periodically do centripetal motion and centrifugal motion in the washing basket. The cleaning method of the invention can separate the impurities of class B and class C in different spaces for removal, while the cleaning method of the vegetable washer in the prior art can only separate the impurities of class B and class C.

Description

Vegetable washing method capable of splitting and shunting impurities and vegetable washing machine
Technical Field
The invention relates to a cleaning method of fruits and vegetables and a vegetable washing machine applying the method. In particular to a method and a machine which can separate various impurities from fruits and vegetables and place the impurities in different spaces in the cleaning process.
Background
Firstly, we know what impurities can be found in unwashed vegetables, namely, the first kind of impurities which can not be seen by naked eyes, such as pesticide virus bacteria and the like remained on the surfaces of fruits and vegetables, the second kind of impurities which are seen by naked eyes and exist in an attached or included mode and have larger specific gravity, such as sand grains, soil and the like, and the third kind of impurities which are seen by naked eyes and exist in an attached or included mode but have smaller specific gravity, such as yellow leaf weed, hair, cabbage worms and the like.
The problem that this patent will be solved is to get rid of class B and class C impurity.
Secondly, we analyze how the traditional manual vegetable washing process removes the 3-class impurities in the methyl-ethyl-propylene. Two basins were prepared. Firstly, clear water is filled in a first basin, fruits and vegetables are placed in water to be soaked for a proper time, the class A impurities are dissolved in the water, then a hand is put into the water, a vegetable is constantly stirred in the water and shaken up and down and left and right to enable the class B impurities to fall from a vegetable seam and sink into the water, the class C impurities are thrown out of the vegetable seam (but the vegetable and the impurities still coexist in a barrel), the class B and class C impurities are separated from the vegetable seam, (the clamping degree of the impurities on the surface of a washed object and the clamping degree of the vegetable to the impurities are damaged, the class B and class C impurities are separated, the class C and class C impurities are also called as X operation), the vegetable is also grabbed, the actions are repeated until the vegetables in the basin are all operated once, and half of the whole vegetable washing process is completed. The vegetables and the impurities of the category 3A, B and C are co-located in one basin. And then, the hand is put into the water for multiple times, a small bunch of vegetables are fished up each time, the vegetables are continuously dipped on the water surface for spin-drying, and then the vegetables are put into a second basin until the vegetables in the first basin are completely transferred into the second basin, and the impurities of the first type, the second type and the third type and the water are still left in the first basin, so that the vegetables and the impurities of the second type and the third type are separately placed, namely the separate placement is called as Y operation), and thus the next half of the whole process of vegetable washing is completed.
X operation + Y operation = one complete vegetable washing process.
Of course, the water and the impurities in the first basin can be poured out and then the first basin is filled with water, and the process of washing vegetables for the second time can be repeated (X operation + Y operation). In fact, the process of changing water and repeating X + Y is also adopted for washing vegetables in daily life.
Now, if we only do X operation, but not do Y operation to wash the vegetables clean, in the above example, after the X operation is completed in the first basin, the vegetables are not moved to the second basin to complete the Y operation of separating the vegetables and impurities, but a water pump is used to pump the water in the first barrel, at the time, the vegetables and the class A, B and C3 impurities are stored in the basins and mixed together, at this time, if you want to fry the vegetables without touching the dirty hands, the people dare to eat, which is not different from frying all the impurities in the vegetable sand grains of the weeds and the insects together.
Thus, the impurities of B and C are not completely removed without Y operation. The vegetables cannot be washed no matter how many times of the X operation is repeated without Y operation, strictly speaking, the vegetables are only half washed, and the vegetables are not washed well and are washed completely.
The development history of the vegetable washer is reviewed below.
The earliest vegetable washers had no mechanical moving parts and are now called static vegetable washers. Aims to degrade the residual pesticide in the fruits and vegetables. The method comprises introducing water and ozone into a sealed container, soaking fruits and vegetables in the water containing dissolved ozone for a proper time, and soaking with ozone O3The strong oxidation of the pesticide makes the pesticide remained on the surface of the fruit and vegetable dissolved in water after being decomposed and poured out along with the water. For the purpose of washing off only residual pesticides on vegetable surfaces, i.e. class A impuritiesBy nature, such vegetable washers are still widely sold and popular.
Later, patent No. 912008210 discloses a vegetable washer with mechanical motion, now called dynamic vegetable washer. The washing machine has the scheme that a washing basket (in the original text of the patent, the washing basket is called an inner barrel capable of permeating water, and the washing barrel is called an outer barrel, the washing basket and the washing barrel are called as the washing basket and the washing barrel in a unified way for unified name and no disorder), the bottom of the washing machine is planar or quasi-planar, a rotating shaft penetrating from the bottom is arranged in the center of the bottom of the washing machine, a water inlet and a water outlet are arranged at the periphery of the bottom of the washing machine, a motor and an electronic control device for driving the washing basket to rotate are arranged in the machine case, and a water baffle is fixed on the inner surface of the upper part of the. Put into washing basket with fruit and vegetable etc. during the use, drive the washing basket by the motor and rotate, thereby force rivers by centrifugal force by in the washing basket get rid of the clearance of basket and bucket rise to the top of basket again and meet and hinder the clearance of falling back in the basket again by centrifugal force and get rid of the clearance of basket and bucket, the reciprocating flow of circulation like this, the gap of the vegetables in the basket is all passed in the circulation of every time of per share rivers, thereby form quick relative motion with the surface of fruit vegetables, produce the friction, come to divide impurity and vegetables to break apart and accomplished the X operation promptly. It should be noted here that the washing action is due to the friction of water passing through, rather than the impact of water falling, and the packaging and television advertising of the existing vegetable washers heavily emphasize the vegetable washing action of such water falling in the vegetable washer, and is called sprinkling. This is a technical prejudice, which is discussed below.
The patent solution ingeniously solves the problem of vegetable washing X operation (except for the problem of turning over vegetables), and does not solve the problem of Y operation (see fig. 21 and 22).
For example, in the case of the problem of arranging the water blocking member higher than the washing basket in the tub, there are many equivalent changes, such as the water blocking member can be arranged at the upper part of the washing tub and also arranged at the lower surface of the tub cover, or an independent inner cover ring, even without the water blocking plate, the water naturally falls when hitting the tub cover (the falling phenomenon is called spraying), and then the center of the upper basket cavity is an instant low-pressure area to suck the water above into the basket, and the water blocking member, the water blocking rib, and the water blocking cover can all achieve substantially the same function and achieve substantially the same effect by substantially the same means. Although such a change in the shape of the position of the water guard may cause a difference in the position of the water falling into the basket, such a difference in the water falling point does not provide a change in the effect of washing vegetables.
For another example, regarding the problem of arranging a water-stirring mechanism under the washing basket, the original patent proposal is that a washing tray is arranged under the washing basket and emphasizes that the washing tray and the washing basket are synchronous and have no relative movement. In light of this teaching, it will be readily apparent to those skilled in the art of molding when the wash basket is molded of plastic that the wash basket and wash tray may be molded as a single unit, simplifying the wash tray to a water-repellant bulge in the bottom of the basket. Similarly, the shape of the protrusion can be changed into countless same shapes, such as cross shape, X shape, rice shape, swastika shape, etc., and the protrusion can be called as a water-stirring plate, a water-stirring strip, a water-stirring rib, or a protrusion with water stirring function.
Incidentally, most of the dynamic vegetable washers on the market at present are provided with an ozone generator, an ultrasonic generator, a plasma generator or an ultraviolet generator, and the functions of the static vegetable washer are added. So as to remove class a impurities.
The vegetable washer in the prior art has a structure that the power is arranged above the basket, namely, the motor is arranged on the barrel cover of the washing barrel. The washing basket has a structure that a rod-shaped long shaft is protruded from the center of the bottom surface, and the shaft is matched with a motor output shaft on the lower bottom surface of the barrel cover. The bottom surface of the washing tub has raised shaft seats which cooperate with recessed holes in the lower bottom surface of the basket to carry the basket (see fig. 23 and 26).
Referring to fig. 22 and 23 and fig. 24 and fig. 25 and 26, these two prior art vegetable washers are characterized in that:
1, the function and the space for separately placing the class B class C class impurities are not provided.
2, the center of the bottom of the washing bucket is provided with a rotating shaft 102 (see figure 22 and figure 25) which is penetrated upwards or a raised shaft seat 202 (see figure 23 and figure 26) (thereby leading to:)
3, the water outlet can be arranged at the periphery of the bottom of the washing barrel. 4, in the sewage discharge method, the rotary suction force of the vortex center cannot be utilized for sewage discharge.
5, the rotating shaft 102 or the raised shaft seat 202 penetrating the center of the bottom of the washing barrel plays a bearing role for the washing basket (a shaft sleeve 104 is sleeved on the shaft 102 in order to increase the stress surface)
6, the bottom of the washing barrel is planar or quasi-planar
7 convex boss buckling structure (figure 22 and figure 25) or convex rod-shaped long shaft (figure 24 and figure 26) is arranged at the center of the basket bottom
8, the basket opening of the washing basket is opened.
Because the vegetable washer in the prior art has the structural characteristics, after the vegetable washer is used for washing vegetables, the following three problems exist:
the first problem is that the third-class impurities are still mixed with the vegetables because the third-class impurities are thrown out of the basket along with the circulation of the water flow, rise above the basket along with the water flow along the gap between the basket and the barrel, and fall back into the vegetables in the basket along with the water flow (if the falling of the water is called spraying, the impurities are sprayed into the basket while the water is sprayed downwards), so that the third-class impurities cannot be removed separately regardless of the washing times and are finally mixed in the vegetables.
The second problem is that the type b impurities remain partially mixed with the dishes, and a portion is accumulated around the central rotating shaft 102 of the bottom of the washing tub and is not discharged. In the process of draining, along with the reduction of water, the water flow does not rise along the gap between the barrel and the basket any more, the impurities of the class B are heavy and sink to the bottom of the barrel, the gradually rotated water flow is rolled to the center of the barrel bottom and gathered around a rotating shaft at the center of the barrel, the center of the barrel bottom of the vegetable washer in the prior art is the rotating shaft, and the water outlet is only arranged on the periphery of the barrel bottom, so the impurities of the class B cannot be drained. Many consumers do not find this problem because the shaft sleeve mounted on the spindle under the basket blocks the view. The impurities of the type B are partially left at the bottom of the barrel, and are partially mixed in the dishes to be taken away by the user along with the dishes. A small part is discharged from a water outlet close to the periphery of the barrel along with the water flow. That is to say, after washing, the impurities of the type B are mixed with the vegetables in a barrel. When water is discharged into the barrel again and the machine is started, the impurities of the type B at the bottom of the barrel participate in the up-and-down circulation motion of the water. (e.g., the consumer reflects washing the amaranth with a prior art washer, then frying the amaranth to eat, with the upper and lower teeth always ground to a grit).
The third problem is that the cleaning dead angle exists, which is not beneficial to thoroughly cleaning the dishes. In the process of washing vegetables, no matter how many times the vegetables are washed, the vegetables are relatively intensively remained near the side wall in the washing basket in the washing process, and do not move circumferentially (relative to the circumferential movement of the basket), do not move centripetally or do not move centrifugally again (except that the vegetables are thrown to the periphery of the washing basket for the first time when the machine just starts to operate). That is, when the vegetables are washed by water flow, the vegetables are kept at a fixed upstream surface, and the washing angle of the water is fixed (because the water flow circulates according to a fixed path), so that the vegetables are easy to be washed dead, the vegetables are not easy to be thoroughly washed, and the washing degree is greatly reduced.
That is, the existing vegetable washing machine on the market only completes the X operation of vegetable washing, cannot complete the Y operation, and cannot solve the problem of turning over the fruits and vegetables in the X operation, so that the X operation is not completely completed. Overall only 40% of the overall process may be completed. After the vegetable washing machine is used for washing, residual pesticide can be dissolved into water under the action of ozone and drained with water, so that the problem of degradation and removal of class A impurities is solved, class C impurities such as yellow leaf rotten leaves of weed insects and vegetables are still mixed in a basket and are not separated from the vegetables, class B impurities such as sand grains and soil are gathered in the center of a washing barrel, part of the sand grains and soil are clamped in the vegetables and are not drained with water, and when the vegetables are washed by water for the second time, the sand and soil are stirred together with a vegetable copolymerization barrel and are not separately arranged along with the rotation of the washing basket along with the water filling of the vegetable washing machine, and Y operation can be finished by manual washing for a plurality of times. That is, the manual labor can not be really liberated, the whole vegetable washing process (X operation + Y operation) can be completely finished by the machine, strictly speaking, the vegetable washing process can not be finished, and only half of the vegetable washing process can be finished, even half of the vegetable washing process can not be finished (because the vegetable is not fully turned over, dead corners exist, and the cleaning degree is greatly reduced).
The three existing problems are the reasons why the vegetable washer cannot be popularized on a large scale for a long time. Consumers who do not find these problems may buy such machines. A consumer who has bought such a machine and found these three problems may not recommend that the machine be bought to friends and relatives. (unless the purpose is to degrade the residual pesticide on the vegetable surface, the operation Y is required to be manually completed, so that the difference is not great compared with the static vegetable washing machine, the impurities in the A class are removed, but the problem of completely removing the impurities in the B class and the C class is not solved).
The three problems are not solved, namely the Y-operation cleaning is manually completed, so that the significance of the dynamic vegetable washing machine is not large, for example, in cold winter, people can wash vegetables twice by hands after washing the vegetables by the vegetable washing machine, or the hands cannot be prevented from being soaked in cold water, for example, fashionable women who are nailed with red oil cosmetics cannot wash the vegetables without makeup removal, for example, in occasions of eating vegetables such as western-style food, or the hidden danger of infectious diseases that the hands of the hand-washed vegetables touch the vegetables cannot be avoided.
If the three problems are solved, the dynamic vegetable washer is a qualitative leap, because if the three problems are solved (and ozone is added to remove the class A impurities), all the impurities in the vegetables can be removed.
The three existing problems are solved, the vegetable washing machine industry cannot be solved for 20 years, researchers and manufacturers try to solve the three problems of the existing vegetable washing machine, the vegetable washing machine really and completely finishes the whole vegetable washing process, namely X and Y operations, and the picture can greatly tell consumers that the my vegetable washing machine can separate and separate impurities and can separate and place the impurities, and the user can really pour the vegetable into a pot to fry the vegetable after being washed by the machine.
Researchers have designed various complicated methods theoretically for 20 years, and try to solve the 3 problems, for example, in order to solve the problem of turning over and turning over vegetables, some solutions design the vegetable washer into a structure similar to a drum washing machine to drive the turning over and turning over of vegetables, see the technical scheme of the drum vegetable washer with patent number 012372013. For another example, in order to complete Y operation, namely, the vegetables and the class A, B and C3 impurities in the vegetables are respectively kept in different spaces, a manipulator is additionally designed on the existing vegetable washer by some people to simulate hands, and the vegetables are grabbed and clamped from water by using mechanical fingers and placed in another basin. These expensive explorations, while not as effective as possible, are clearly worthwhile as predecessors for our successors.
The three problems are difficult to solve because the existing vegetable washing machine on the market obviously does not come out of the shadow of the washing machine (for example, the washing basket and the washing tub are open and not covered, the washing tub bottom has a rotating shaft which penetrates upwards in the same center as the washing tub bottom, the drainage opening is arranged on the periphery of the tub bottom, and the like), and the three problems can not be solved. The vegetable washing is different from the washing of clothes, firstly, the clothes are dirty and dirty, and the mud, sand, weeds, yellow leaves and the like are not generated, and the clothes only contain class A impurities, namely sweat stains of dirt and dust attached to the surfaces of the clothes, so that class B impurities and class C impurities do not need to be picked up and separated, and the washing work is relatively easy. Secondly, the water after washing the clothes can also be directly discharged without blocking a drain pipe and a drain valve, but the washing of the vegetables is different, and a great amount of water-insoluble class B impurities and class C impurities in the vegetables can block the pipe orifice of a drain pipe if the water-insoluble class B impurities and the class C impurities are directly discharged into the drain pipe together with the water. Even if the pipe opening is not blocked, the class-C impurities enter the sewage discharge pipe, the rubber plug is easily clamped at the rubber plug of the drain valve, so that the rubber plug is not closed in place and water is leaked.
Through years of research, the patent solves all three problems at once. And overcomes the technical prejudice of washing vegetables by spraying. The cleaning degree of the vegetables is changed, and an unexpected remarkable effect is achieved, namely all impurities in the vegetables are completely removed. Moreover, the machines used to implement the present patent are much less expensive to manufacture than many of the solutions used over the last two decades.
Disclosure of Invention
The invention discloses a vegetable washing method capable of splitting and separating impurities and a machine for implementing the method, which are also called a central pollution discharge vegetable washing machine with an impurity retention device, and the device for solving the three problems of the existing vegetable washing machine is simple in structure, low in manufacturing cost, ingenious in method and remarkable in effect. Has a qualitative leap. This is not a publicity but is based on the reason that the effect is obvious because the impurity of class 3 of ethylene propylene alphabets and the dish itself have 4 kinds of substances just mixed in a basket, and after washing, the 4 kinds of substances are automatically distributed in four different spaces just like human eyes and hand picking. The vegetables in the basket can be directly fried in the pot instead of being fried in the pot together with the impurities. The process is clever because achieving such significant improvements does not necessitate the addition of many more complex machines. And does not add much cost.
The invention relates to a vegetable washing method capable of separating and placing impurities, which comprises the steps of putting fruits and vegetables and the like into a permeable washing basket arranged in a washing barrel with a cover, driving the washing basket to rotate by a motor, so as to force water in the washing barrel to pass through a motion path, throwing the water from the inside of the washing basket to a basket gap by centrifugal force, then rising to the upper part of the basket, then being guided to the center by resistance, then falling back to the inside of the basket, then throwing the water to the basket gap by the centrifugal force, circularly and repeatedly flowing in the manner, simply weighing the circulation motion in the barrel, enabling each circulation of each water flow to pass through the gaps of the vegetables in the basket, thus forming rapid relative motion with the surfaces of the fruits and the vegetables, generating friction to destroy the attachment looseness of the impurities on the surfaces of the washed objects and the clamping degree of the impurities by the vegetables, connecting the washing barrel or a washing barrel cover with a machine box, and controlling and driving the motion by the motor and an electronic control device arranged in the machine box in the vegetable washing process, the method is characterized by having at least one of the following A and B technical characteristics, or at least two of the following A, B and C technical characteristics:
the method for purifying vegetables in a basket is characterized in that water flow which is in a cavity of a washing barrel and performs internal circulation motion is filtered, impurities thrown out of the washing basket together with the water flow are prevented from circularly falling back into the basket together with the water flow, ①, a filter device is arranged in the washing barrel, a path through which the water flow rises and falls back is formed, the filter device receives the water flow below a water flow turning point, the water flow downwards passes through a filter screen and returns back into the basket, the filter screen of the filter device prevents impurities carried in the water flow from passing through and retains the impurities on the filter screen, so that the water flow and the impurities are separated, the water flow is the water flow circulating in the washing barrel, ②, the filter device is also called as a filter or a basket opening and consists of the filter screen and a frame supporting the filter screen, the filter device is arranged in the washing barrel, is arranged near the opening of the washing basket, is high enough above the washing basket opening, has a shape and an area enough for the impurities falling in the washing barrel, the shape and the area of the filter device is not limited to be a filter, the filter device is a filter which is detachably connected with the filter, the filter is used for collecting impurities contained in the water flow after the water flow is collected, the water flow, the impurities, the impurity is collected from a filter device, the filter device is also called as a filter, the filter is used for collecting impurity collecting device is used for collecting impurities in the washing barrel, the impurity collecting process of ④, the vegetable;
the characteristic B is that a vortex center pollution discharge method is adopted to discharge sewage and impurities to the outside, ① is adopted to arrange a drainage and pollution discharge outlet at the center of the bottom of a washing barrel or at the center of a vortex when water flow at the bottom of the washing barrel is discharged, the drainage and pollution discharge outlet is a center opening which can be opened and closed, the center opening is connected with the outside through a drainage pipe, the center drainage and pollution discharge outlet is closed in the process of rotating fruits and vegetables, the center drainage and pollution discharge outlet is opened in the process of discharging water in the washing barrel to the outside, ② is that water in the washing barrel keeps rotating due to inertia or the driving of the washing basket rotating in the process of discharging water in the washing barrel to the outside, so that vortex drainage is formed, the opening of the center drainage pipe at the bottom of the barrel is also the center of the vortex, the water at the center of the vortex center rotates forcefully to discharge impurities, ③ the washing basket is a washing basket which is connected with the center of the bottom of the washing barrel without a rotating shaft, a special bearing device is arranged in the washing barrel to bear the basket and a special positioning device to transfer the position of the washing basket and the special torque force of the washing barrel to the washing barrel, and transfer the position of the washing barrel to the washing barrel, which is specially limited by the special;
the characteristic C is that it has the function of forcing the fruit and vegetable in the washing basket to do centripetal and centrifugal motion periodically, thus providing a method for automatically turning over and rolling the fruit and vegetable in the basket, comprising ①, in the course of discharging dirt from the center of the vortex, using water flow to rotate and discharge towards the center to drive the fruit and vegetable to roll or turn over towards the center of the basket, after the water discharge of the washing barrel is finished and the water discharge is closed, in the course of washing the basket is finished, using centrifugal force to force the fruit and vegetable to roll and turn towards the edge of the basket, simulating the effect of human hand turning over the fruit and vegetable in water, ② the frequency of centripetal and centrifugal motion of the fruit and vegetable in the washing basket is in direct proportion to the frequency of water changing and washing, N times of water changing and washing can force N times of centripetal and centrifugal motion of the fruit and vegetable, N is a natural number.
Therefore, each vegetable is changed into a placing angle and a surface as the upstream surface every time water is changed. And the water is turned over one time for each time, and the turning over is not as frequent and violent as the clothes are turned over by the impeller of the washing machine, so that the fruits and the vegetables are not damaged. A vegetable washing procedure of more than 20 minutes can be changed by 4 to 5 times of water, the vegetables are turned over for 4 to 5 times, different placing angles are changed, and 4 to 5 different upstream surfaces exist, so that the problem of vegetable washing and dead angle storage in the prior art is thoroughly solved.
As is known, the cross-section of the tub cavity of the washing tub of a vegetable washing machine and the cross-section of the washing basket are a pair of concentric circles, so that the rotation axis of the washing basket naturally passes through the centers of the pair of concentric circles. Therefore, it is a matter of course that the rotating shaft (see fig. 22 and 25) penetrating upwards is arranged at the center of the bottom of the vegetable washer in the prior art or the shaft seat (see fig. 23 and 26) is arranged at the center of the bottom of the vegetable washer, and the arrangement is a necessary association for a person skilled in the art. The innovative thinking and creative labor of the invention are to abandon the conventional and conventional setting scheme. The center of the bottom of the washing barrel filled with water is provided with a water outlet, so that the pollution discharge effect is substantially improved. If the bottom of the barrel is made into a funnel shape, the sewage can be discharged completely.
As is known, the vegetable washing machine in the prior art emphasizes vegetable washing by spraying, is called as a spraying technology, namely emphasizing that water flow turns back from the upper surface and falls into a washing basket, and the water flow falls into the basket to play a main role in vegetable washing, and is a technical prejudice (see the following argument for details), which guides people to open a washing basket opening as much as possible without covering so as to avoid slowing down the falling speed of the water flow and influencing the falling point of the water. But the washing effect is remarkably improved.
The vegetable washing method capable of separating and placing impurities can be further characterized in that the bottom of the bucket is made into a funnel-shaped bottom with a low center and high peripheries to strengthen the impurities to be close to the center and further strengthen the impurity discharge of vortex water flow, the funnel-shaped cavity can be provided with rotating blades to strengthen the water stirring effect, and the rotating shafts of the blades can be used as rotating shafts of the washing basket extending downwards. The preferred washing basket bottom is a flat bottom or funnel bottom.
The vegetable washing method capable of separating and containing impurities can also be characterized in that the method for preventing the vegetable leaves, branches and other larger objects from entering the drain pipe to block the drain pipe is to arrange a filter screen on the lower drain port of the basket to prevent the vegetable leaves with larger volume from passing through without obstructing the passage and discharge of silt. The framework of the under-basket filter can be used as a supporting component of the basket or not, the density of meshes of a filter screen of the filter is proper to prevent larger impurities such as vegetable leaves and vegetable branches and the like from passing through and allow silt, sand and grains to pass through, and the meshes can be large or small within the range, and the preferable pore diameter is between 2MM and 5 MM.
The vegetable washing method capable of separating and placing impurities can also comprise the following technical characteristics that the motor drives the washing basket to rotate, the power of the motor can be transmitted to the basket from any direction of the basket and can be transmitted to the basket from the upper part, the lower part or the side of the basket, and when the power is transmitted to the basket from the upper part of the basket, the transmission method can select to utilize the framework of the filter at the basket opening as a transmission part or not select to utilize the framework of the filter at the basket opening as a transmission part.

Fig. 4 is a schematic view of a washing tub and cabinet according to a first embodiment of the present invention, i.e., a view of a basket mouth filter and a washing basket and under-basket filter and tray assembly not yet installed, showing that the spring catches 1-6 of the tub cover and tub body are not latched, so that the tub cover is bounced at a certain angle due to the spring action of the hinge shaft 1-5.
Referring to fig. 5 and 6, to facilitate understanding of the present embodiment, fig. 5 provides a schematic view of the combination of the under-basket filter and the multi-functional tray of the first embodiment of the present invention. Fig. 6 is a view illustrating the installation of fig. 5 to fig. 4, in which the under-basket filter 8 and the multi-functional tray 7 according to the first embodiment of the present invention are combined and installed in the washing tub 5 (for clarity, the filter net of the under-basket filter is not shown).
Referring to fig. 7 and 8, fig. 7 is a schematic cross-sectional view of a basket filter according to a first embodiment of the present invention, in which the pore size of the mesh is not drawn to scale as a schematic view, and the mesh of the basket filter in each of the other figures of the first embodiment other than fig. 7 is not drawn. Fig. 8 is a perspective view of a basket filter according to a first embodiment of the present invention.
When the washing basket works, fruits and vegetables are placed in the washing basket, the plug pins 2-3 of the basket opening filter are inserted into the plug holes 3-2 of the washing basket opening, and the basket opening filter 2 is covered on the basket opening. Then the cover of the barrel is covered, and the output shaft 1-4 of the speed reducing motor can be conveniently inserted into the shaft sleeve 2-1. And then the water inlet valve is opened, and the water inlet valve is closed when water is fed to a preset water level under the control of the water level controller. Then the motor is started, at this time, the output shaft 1-4 of the speed reducing motor rotates and drives the shaft sleeve 2-1 to rotate through the spline 2-2 with loose large clearance so as to drive the basket mouth filter 2 to rotate. Because the latch 2-3 of the basket opening filter is inserted into the jack 3-2 of the basket opening downwards, the whole washing basket is driven to rotate. And the head-neck bolt 7-3 of the tray 7 is upwards inserted into a pin hole matched with the bottom of the washing basket, so that the washing basket drives the tray to rotate. Because the tray has a shaft 7-2 extending downwards and rotating synchronously with the basket in the circumferential direction, two water-stirring sheets fixed at the tail ends of the shaft rotate synchronously to stir water, and because the shaft 7-2 is in interference fit with a central tubular bearing 8-1 of the filter under the basket, the shaft is fixed with the bearing 8-1 in the axial direction, and the filter under the basket is fixed on the barrel body through a screw 8-3, the tray is fixed on the barrel body in the axial direction, and the tray also has the function of supporting the washing basket.
Along with the fast rotation of the washing basket, the fruits and vegetables and the water flow in the basket do centrifugal motion, the fruits and vegetables move to the periphery of the basket, are blocked by the side wall of the basket and stay near the side wall, the water flow is thrown to the gap 4 between the basket and the barrel by the centrifugal force and then rises to the upper part of the basket, at this time, the fruits and vegetables are thrown out along with the water, part of the impurities of the type B are deposited at the bottom of the barrel, the rest of the impurities of the type B and the impurities of the type C are thrown out along with the rising water flow and rise to the upper part of the basket, the impurities fall back to the center on the filter screen of the basket mouth filter under the obstruction of the water retaining ring additionally arranged on the upper barrel cover or the upper part of the barrel, the impurities cannot pass through dense meshes and are retained on the filter screen of the basket mouth filter to finish Y operation, the water flow passes through the filter screen of the basket mouth filter and continuously falls into the gap between the basket and the barrel, and is, each circulation of each water flow passes through the slits of the vegetables in the basket, so that the water flow forms quick relative movement with the surfaces of the fruits and vegetables to generate friction, and impurities and the vegetables are separated to finish the X operation. The most important point is that each circulation of each water flow takes the class B and class C impurities mixed in the vegetables out of the washing basket, brings the impurities into the basket opening filter and keeps the impurities in the basket opening filter, namely, the impurities leave the basket and do not enter the basket, and leave the basket and do not return, and leave the vegetables and do not return to the vegetables. In the embodiment, 200 revolutions per minute of the washing basket of the vegetable washing machine are set, one program takes 20 minutes to about 4000 revolutions, even if a little impurity is brought up by each revolution (note that the impurity does not fall back into the basket when the impurity comes up), and if the impurity does not fall back into the basket when the impurity comes up, the impurity cannot be cleaned by 4000 bits. Impurities in the basket are reduced every second, less than the last second, and less than the second, and are gradually retained in the basket mouth filter. The water flow plays a role in scouring and also plays a role in impurity carrying, and the water flow only plays a role in scouring in the vegetable washing machine in the prior art.
In the vegetable washer in the prior art, because no basket opening filter is arranged, impurities are thrown out from the basket side, rise to the basket opening and are sprayed from the basket opening to fall back into the basket, and the C-type impurities and part of B-type impurities are circulated together with water for many times no matter how many times the water flow circulates from the upper part to the lower part, from the inner part to the outer part. The water in the washing barrel is discharged, and the class-C impurities and part of class-B impurities are still mixed in the vegetables, particularly the situation of leaf vegetables is worse. Therefore, in the advertisement video of the prior art vegetable washing machine, vegetables with a large amount of impurities, such as the garland chrysanthemum, the amaranth and the watercress, are never seen as the exemplary vegetable washing, and the vegetables with a large amount of impurities, such as the apple, the peach and the lettuce, are often seen as easily-washed food materials.
The basket filter has a function of preventing the backflow of the foreign substances and storing the foreign substances, and is also called a foreign substance stopper or a foreign substance trap.
In the present embodiment, the control panel 23 is preset with a plurality of time schemes and rotation speed schemes for selection, so as to adapt to the preferences of different users and the requirements of different fruits and vegetables. The protocol of this example sets the entire wash program for 24 minutes and runs four times. Each time of water intake takes 1 minute and then spin washing takes 4 minutes and then the water flow starts to open the drain valve and the water is drained while spinning for about one minute, completing one time of washing. The whole procedure was carried out for four such water-in-wash-out cycles. The clockwise rotation and the counterclockwise rotation may be alternately performed during 4 minutes of the spin washing thereof.
The operating feature of this example at minute 6 will now be discussed, namely the use of vortex core blowdown to remove sewage and impurities. The controller opens the drain valve according to the set program, at this time, the washing basket continues to rotate clockwise, the water flow continues to rotate clockwise, and the water flow forms a vortex at the center of the washing barrel and flows out of the washing barrel and is discharged to the outside through the drain pipe, because the drain pipe 10 is opened at the center of the barrel bottom of the washing barrel 5, at this time, the water rotating speed near the drain pipe opening is very fast, the class B impurities deposited at the funnel-shaped barrel bottom are quickly rolled into the drain pipe to be discharged, and the water flow can continue to rotate due to inertia after entering the drain pipe, and advances while rotating, the movement of the water flow is similar to the movement of a bullet along the rifling line in the barrel, the class C impurities can be more thoroughly discharged to the outside, and the accumulation of sand particles near the rubber plug of.
And before the drainage valve is not opened, when a part of heavier class B impurities rotate to the opening of the drainage pipe at the center of the bottom of the barrel, the impurities drop into the drainage pipe and wait for drainage, namely, the drainage pipe provides a retention space for the class B impurities, and the retention device for the class B impurities is formed. Thus, during the rotation of the basket, the class B impurities in the tub are reduced every second, which is less than the previous second and less than the next second. In the vegetable washer in the prior art, the central opening of the bucket bottom is not provided, so that most of the class B impurities (except part of the class B impurities which rise with water and circulate with water) are accumulated around the central rotating shaft 102 of the bucket bottom.
The prior vegetable washing machine cannot achieve the effect because the rotating shaft is arranged at the center of the bottom case of the washing barrel, and the opening of the drain pipe can only be arranged at the edge of the bottom of the washing barrel, which is shown in fig. 22 and 23. First, a large amount of class b impurities are accumulated in a central region of the tub bottom (i.e., near the rotation shaft of fig. 22 or near the shaft seat of fig. 23) due to the rotation of water, and the impurities cannot be discharged from the drain port provided at the rim of the tub bottom. Secondly, the sand particles accumulated near the rotating shaft for a long time are easily drawn into the gap between the rotating shaft and the waterproof leather cup, so that the leather cup is scratched, the water is not tightly sealed and leaked due to the scratching of the leather cup, and the hydromechanical property of the third sewage flowing to the central water outlet while rotating cannot be utilized to take away impurities, particularly the impurities of the class B. Fourthly, water flow can not be discharged after entering the drain pipe in a reciprocating motion manner, and sand grains are easy to accumulate near the rubber plug in the drain valve when flowing through the drain valve, so that the rubber plug is easy to be untight, and the water leakage phenomenon is caused.
As is known, the cross-section of the tub cavity of the washing tub of a vegetable washing machine and the cross-section of the washing basket are a pair of concentric circles, so that the rotation axis of the washing basket naturally passes through the centers of the pair of concentric circles. Therefore, the rotating shaft (see figure 22) penetrating upwards or the shaft seat (see figure 23) arranged at the center of the bottom of the vegetable washer in the prior art is also natural and can not be thick, and the arrangement is a necessary association for a person skilled in the art. The innovative thinking and creative labor of the invention are to abandon the conventional and conventional setting scheme. The center of the bottom of the washing barrel filled with water is provided with a water outlet, so that the pollution discharge effect is substantially improved. If the bottom of the barrel is made into a funnel shape, the sewage can be discharged completely.
Now, the working characteristics of the embodiment from the 6 th minute to the 8 th minute are discussed, namely, the fruits and vegetables periodically do centripetal movement and centrifugal movement, so that the placing angles of the fruits and vegetables in the basket are turned over and turned over. And in the 6 th minute, the controller opens the drain valve according to a set program, at the moment, the washing basket continues to rotate clockwise, the water flow continues to rotate clockwise, and because the drain pipe 10 is opened at the center of the bottom of the washing barrel 5, the water flow rotates to the center from the periphery, and a vortex is formed at the center of the washing barrel and flows out of the washing barrel in a rotating manner and is discharged to the outside through the drain pipe. The water flow also drives the fruits and vegetables to move towards the center of the basket (including rolling and turning). Until the water is drained, the drain valve is closed. The vegetables and fruits also change from "relatively concentrated in the vicinity of the side wall in the washing basket" to "relatively concentrated in the vicinity of the center in the washing basket". And in the 7 th minute, the water inlet valve is opened for the second time according to the set program, and the water inlet valve is closed after water is fed to the preset water level under the control of the water level controller. And then in 8 th minute, the motor is started, and the output shaft 1-4 of the speed reducing motor rotates and drives the shaft sleeve 2-1 to rotate through the spline 2-2 with loose and large clearance so as to drive the basket opening filter 2 to rotate. Because the latch 2-3 of the basket opening filter is inserted into the jack 3-2 of the basket opening downwards, the whole washing basket is driven to rotate. Thereby driving the water-stirring plate 7-1 to rotate and stir water, and further driving the whole barrel of water in the washing barrel to rotate together. Along with the rapid rotation of the washing basket, the fruits and vegetables and the water flow in the basket do centrifugal motion, the fruits and vegetables move to the periphery of the basket, are blocked by the side walls of the basket and stay near the side walls, and return to the original position before water drainage. The process of the centrifugal motion is the same as the process of the centripetal motion, and the process of the centrifugal motion is the process of the full rolling and turning of the fruits and the vegetables, so that the effect of turning the fruits and the vegetables in the water by replacing hands is achieved. Thus, each vegetable is subjected to centripetal and centrifugal movement once for each time, and each vegetable is subjected to a placing angle and a face as a water face to be subjected to head-on washing and washing once for each time for changing water. And the water is turned over one time for each time, and the turning over is not as frequent and violent as the clothes are turned over by the impeller of the washing machine, so that the fruits and the vegetables are not damaged.

New embodiments, which are derived from a simple recombination of parts of the above embodiments, belong to the scope of protection of the patent with equivalent alterations. Since many common parts and known transmission mechanisms in the mechanical field can be substituted for each other to achieve the same purpose, any embodiment that is modified is within the scope of the patent of the equivalent modification.
It is a technical prejudice to demonstrate that the vegetable washer mainly sprays vegetables by water flow. As is well known, the vegetable washers in the prior art all emphasize that the vegetable washers wash vegetables by spraying, and are called as spraying technology, namely, emphasizing that water flow returns back to a washing basket from the upper side, and the key point of the vegetable washing is that the water flow falls above the vegetables. The method can be seen from the television advertisement of the vegetable washing machine of each manufacturer and the sale webpage of the online vegetable washing machine. This is a technical prejudice that guides people to leave the washing basket as open as possible, without the basket being able to be covered in order to slow down the falling speed of the water flow and to influence the falling point of the water. In contrast, the basket opening is covered with the filter, and a large amount of class-C impurities and part of class-B impurities are accumulated and retained on the filter screen with the compact filter, so that the falling speed of water flow is objectively greatly slowed down, the falling point of water is influenced, and the falling point of water is random and irregular. But the washing effect is remarkably improved. This is just to prove that the so-called "spraying" of the water when it falls is not critical for vegetable washing, that is to say that the phenomenon of spraying of the water is present, but is only a water circulation phenomenon of a dynamic vegetable washer.
It was experimentally confirmed that the washing action is due to the friction of water crossing the crevices of the dish, rather than the shower of water falling, whether the water falling point is in the center of the basket or at the periphery of the basket, i.e. above the dish (note: the dish stays at the periphery of the basket). Since the fruits and vegetables are all in the water container, the falling water cannot be sprayed to the fruits and vegetables wherever the falling water falls. The person swimming in the theory can most easily realize that when a person swims in a swimming pool and suddenly rains in the sky, the head and the shoulders of the person exposed on the water surface can feel raining, but the parts below the water surface, such as the waist and the legs, can not feel raining, and when the person is submerged in the water, the person can not be drenched on the person regardless of the raining in the sky.
The shape of the water returning plate (or called a water blocking rib water blocking strip water blocking sheet and the like) is unimportant and can be a standing sheet with various shapes. In fact, for a single thin washing barrel cover, a common practice of those skilled in the injection molding field is to provide a reinforcing rib to increase the strength thereof, and almost all thin plastic pieces are provided with such a plurality of vertical pieces on the back surface, for example, the reinforcing rib is provided on the lower surface of the stool surface of a daily plastic stool (see fig. 27), and the washing barrel cover has the reinforcing rib according to common knowledge, and thus, the washing barrel cover can objectively and quickly block the falling water flow. In each embodiment of the invention, the reinforcing ribs on the lower surface of the barrel cover of the washing barrel are respectively in a # -shaped, spiral or honeycomb shape (looking up at the figure) without influencing the washing effect.
The following table shows a comparison of a prior art vegetable washer with the first embodiment of the present invention
