Description

Technical Field

[0001] The invention relates to kitchen appliances, in particular to a food processor capable of feeding materials thoroughly. Background Art

[0002] The existing patent CN201610344153.7 discloses an automatic feeding food processing machine, in which a feeding box is provided under the cup cover, and an automatic feeding structure is provided at the bottom of the feeding box which can be opened after being impacted by water flow. When the water in the cup body rotates at high speed with the processing tool, the water flow impacts the impact plate, driving the feeding plate to rotate, so that the feeding port is connected with the hole of the feeding plate, so that the pre-processed food in the feeding box automatically enters the mixing cup body. The patent scheme discloses that the material can be automatically fed under the impact of water flow, but in this scheme, the feeding port is small, and the feeding can only be realized when the feeding port is connected with the hole of the feeding plate. Therefore, after automatic feeding, there will still be a lot of material left in the feeding box that cannot be put into the mixing cup body. In order to solve this problem, the patent also discloses that a protrusion is set between the three feeding ports. Although the protrusion helps the round material to automatically roll into the mixing cup, for sticky materials or small particles, when there is water vapor or water droplets in the feeding box adhering to the inner wall of the feeding box, the material will also adhere to the inner wall of the feeding box and cannot be put into the mixing cup. Therefore, the patent solution cannot guarantee the thoroughness of material feeding. Incomplete feeding not only causes waste of food materials, but also seriously affects the taste of the prepared slurry. At the same time, it also brings cleaning problems to consumers.

[0003] In addition, there is a patent application CN202210854343.9, which discloses a wall-breaking machine that can automatically feed materials. The solution discloses that a rotatable semicircular bottom plate is provided at the bottom of the bean storage cavity, and a feeding cover blade is provided on the semicircular bottom plate. The semicircular bottom plate is connected to the bean storage cavity by bolts. When the water flow impacts the feeding cover blade, the semicircular bottom plate can be easily rotated, and the ingredients in the bean storage cavity are automatically put into the cup body under the action of gravity, so as to realize the appointment of making soy milk. In order to facilitate the automatic feeding of ingredients into the cup body, a semicircular inclined plate is provided at the bottom of the bean storage cavity. Since the semicircular inclined plate is in an inclined state, when the semicircular bottom plate is opened, the ingredients can automatically roll into the cup body along the semicircular inclined plate. Similarly, during the reservation process, when the bean storage cavity stores sticky materials or small particles (such as rice, sesame, etc.), there will inevitably be residual water on the inner wall of the bean storage cavity. Under the viscosity and static electricity of the water, the sticky materials or small particles will be adsorbed on the inner wall of the bean storage cavity and the semicircular inclined plate, so that the materials cannot be automatically put into the cup body. Obviously, this solution still has the problem of more residual ingredients, and the thoroughness of feeding cannot be guaranteed. Summary of the invention

[0032] Alternatively, the barrel comprises a blanking section with an inner diameter gradually decreasing from the discharge port of the barrel upward.

[0033] In order to realize the process of pre-slurrying in a food processing machine, the material in the barrel is automatically put into the pulping chamber. The prior art discloses many solutions: using the rotation of water flow to push the drive plate to open the discharge port of the barrel, and the material in the barrel automatically rolls down the pulping chamber under the action of gravity, such as CN201610344153.7 and CN202210854343.9; there is also a drive motor to drive the switch to open the discharge port to realize automatic unloading. However, no matter what kind of automatic unloading structure, the prior art cannot solve the problem of complete unloading of the barrel.

[0034] The present invention provides a food processing machine, which has a feeding assembly for automatic feeding, wherein a flushing hole is arranged on the peripheral wall of the barrel, and the barrel is arranged in a pulping chamber. When the switch opens the discharge port to discharge the material, the stirring device drives the liquid flow to rotate at a high speed. Since the barrel is eccentrically arranged relative to the pulping chamber, the high-speed rotating liquid flow has more opportunities to enter the barrel cavity through the flushing hole, thereby flushing the material adsorbed on the inner wall of the cavity. The material flushed by the liquid flow will fall into the pulping chamber from the discharge port along with the liquid flow, so that the residual material in the barrel can be discharged more thoroughly. The problem of food waste caused by incomplete automatic feeding in the prior art and affecting the taste of beverages is effectively solved, and the problem of residual materials being difficult to clean up is also solved for consumers.

[0035] In order to make it easier for the rotating liquid flow to enter the barrel through the flushing hole, the present invention particularly requires that the barrel be set eccentrically with respect to the pulping chamber. This is because the high-speed rotating liquid flow will rotate and surge along the inner circumferential wall of the pulping chamber when performing centrifugal motion, and a hollow area without liquid flow will be formed in the central area of ​​the pulping chamber. When the barrel is offset relative to the pulping chamber, one side of the barrel will be closer to the inner circumferential wall of the pulping chamber. When the high-speed rotating liquid flow collides with the inner circumferential wall of the pulping chamber, more liquid flow will directly enter or rebound into the flushing hole. Even the liquid flow that rebounds into the barrel will have a certain impact energy, thereby flushing the material adsorbed on the inner circumferential wall of the barrel. The material flushed by the liquid flow will fall into the pulping chamber through the discharge port along with the liquid flow, and participate in the crushing of the material. The vertical plane where the center line of the barrel and the center line of the pulping chamber are located is defined as plane P, and the vertical plane passing through the center line of the barrel and perpendicular to plane P is defined as plane Q, wherein the flushing hole is preferably arranged on one side of plane Q and close to the inner wall of the pulping chamber, because this side is more conducive to high-speed liquid flow entering the barrel through the flushing hole.

[0036] At the same time, the inventors have found through research that when the center line of the barrel is eccentrically arranged relative to the center line of the pulping chamber, two liquid flow areas with one end wide and the other end narrow will be formed between the outer peripheral wall of the barrel and the inner peripheral wall of the pulping chamber, wherein the end with a larger distance between the outer peripheral wall of the barrel and the inner peripheral wall of the pulping chamber is a wide flow area, and the end with a smaller distance is a narrow flow area, and the wide flow area and the narrow flow area are located on the vertical plane P where the center line of the barrel and the center line of the pulping chamber are located, and are located on both sides of the center line of the barrel. If a flushing hole is provided on the peripheral wall of the barrel on one side of the narrow flow area, during the rotation of the stirring device, the liquid in the pulping chamber rotates at high speed with the stirring device, and the liquid flow will surround the outer peripheral wall of the barrel and rotate back and forth between the wide flow area and the narrow flow area. According to the Laval nozzle principle (also known as the Laval nozzle effect), in the process of the liquid flow moving from the wide flow area → the narrow flow area → the wide flow area, a nozzle-like structure is formed, in which the narrow flow area is equivalent to a narrow throat. When the fluid moves in the nozzle, the fluid flow rate increases significantly when passing through the narrow throat with a small cross-section. At the same time, since the scouring hole is arranged on one side of the narrow flow area, the high-speed flowing liquid flow will enter the cavity of the barrel through the scouring hole to flush the material adsorbed on the inner wall of the cavity. Driven by the liquid flow, the material will be flushed into the pulping chamber along with the liquid flow, so as to achieve more thorough material discharge.

[0037] Although CN201610344153.7 also discloses that the side wall of the feeding box is provided with side wall holes, according to the records in the drawings of the patent, the side wall holes are arranged relatively high, and the side wall holes are multiple small round holes. Moreover, the feeding box is arranged at the center of the cup cover. Therefore, the rotating liquid flow cannot enter the feeding box through the side wall holes, and it is even more impossible to form a flushing of the material in the feeding box (especially the material adsorbed on the inner wall of the feeding box). Obviously, the side wall holes disclosed in the patent are exhaust holes for connecting the cup body and the outside world during pulping, and are used for exhausting. Based on the records of the above patent, those skilled in the art cannot think of using high-speed liquid flow to flush the material adhering to the barrel, so as to achieve more thorough material discharge.

[0049] Embodiment 1:

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The figure shows an embodiment of a self-feeding food processor of the present invention. The food processor comprises a cup body 1 and a cup cover 2 sealedly mounted on the cup body 1. The cup body 1 and the cup cover 2 enclose a pulping chamber 10, and a feeding assembly 3 is arranged in the pulping chamber 10. A stirring device 4 is arranged at the bottom of the pulping chamber 10. The feeding assembly 3 comprises a barrel 31 having a cavity 30. The lower end of the barrel 31 is provided with a discharge port 310 communicating with the cavity 30 and a switch 32 for opening and closing the discharge port 310. The center line 31a of the barrel 31 is eccentrically arranged relative to the center line 10a of the pulping chamber 10. The vertical plane where the center line 31a of the barrel and the center line 10a of the pulping chamber are located is defined as plane P. There are wide flow areas C1 and narrow flow areas C2 with unequal spacing between the outer circumferential wall of the barrel 31 and the inner circumferential wall of the pulping chamber 10, and the wide flow areas C1 and the narrow flow areas C2 are located on a plane P. Driven by the stirring device 4, the liquid flow in the pulping chamber 10 moves back and forth between the wide flow areas C1 and the narrow flow areas C2 to rotate around the outer circumferential wall of the barrel 31, wherein a flushing hole 311 connected to the barrel cavity 30 is provided on the circumferential wall of the barrel 31 adjacent to the narrow flow area C2. When the switch member 32 opens the discharge port 310 to discharge the material, the rotating liquid flow rushes into the cavity 30 through the flushing hole 311 to flush the material, so that the material falls into the pulping chamber 10.

[0051] In this embodiment, the discharge port 310 is a lower port opened at the lower end of the barrel 31, and the switch member 32 is a tray for closing the lower port. The tray 32 is used to support materials, and a driving plate 33 that rotates with the liquid flow is provided at the bottom of the tray 32. The tray 32 is connected to the barrel 31 through a rotating shaft structure 34, and the rotating shaft structure 34 is connected to the peripheral wall of the barrel 31 along the axial direction of the barrel 31. The driving plate 33 and the tray 32 rotate in the horizontal direction relative to the barrel 31 around the rotating shaft structure 34. Among them, the rotating shaft structure 34 includes a pin 341 provided at the bottom of the peripheral wall of the barrel 31 and an axial hole 340 provided on the tray 32. The pin 341 passes through the axial hole 340 from the bottom of the tray 32 to install the tray 32 on the lower port of the barrel 31, and the tray 32 rotates around the pin 341. In addition, a first magnet 323 is arranged on the edge of the tray 32 on the side opposite to the rotating shaft structure 34, and a second magnet 313 opposite to the first magnet 323 is arranged on the peripheral wall of the lower port of the barrel 31, and the first magnet 323 and the second magnet 313 are attracted to each other so that the tray 32 assists in closing at the lower port of the barrel 31.

[0052] In this embodiment, the center line 31a of the barrel, the center line of the rotating shaft structure and the center line 10a of the pulping chamber are located on the same plane, and the center line of the rotating shaft structure coincides with the center line 10a of the pulping chamber, and a spoiler rib 11 is provided on the inner circumferential wall of the pulping chamber 10, and the lower end of the driving plate 33 is lower than the upper end of the spoiler rib 11, wherein, located on the same horizontal cross-section, the rotation radius R1 of the driving plate 33 is smaller than the distance R2 from the center line of the rotating shaft structure to the spoiler rib.

[0053] like Figure 2 , Figure 3 As shown, in this embodiment, the flushing hole 311 is a strip hole extending vertically along the peripheral wall of the barrel 31, and the strip hole 311 is deflected relative to the center line 31a of the barrel, wherein the strip hole has multiple vertically arranged sections. At the same time, a baffle 312 for blocking the liquid flow and allowing the liquid flow to rebound into the flushing hole 311 is arranged on one side of the narrow flow area C2 adjacent to the flushing hole 311, wherein the flushing hole 311 is arranged on both sides of the baffle 312, and the baffle 312 is protrudingly arranged on the outer peripheral wall of the barrel 31.

[0054] like Figure 5 As shown, in this embodiment, the barrel 31 is integrally welded to the cup cover 2 by hot-melt, wherein the feed port 318 at the upper end of the barrel 31 is further provided with a feeding cover 38 for closing the feed port 318, wherein the feeding cover 38 is hinged to the barrel 31 by a hinge 319 provided on the barrel 31. It is convenient for the user to open the feed port 318, and the feeding cover 38 will not be easily lost or difficult to find.

[0055] For the unloading assembly of this embodiment, the unloading assembly includes a barrel, a tray and a driving plate arranged at the bottom of the tray, and the barrel is open at the lower end, the tray closes the lower port of the barrel, the barrel and the tray enclose a cavity, and the material is located in the cavity and is supported by the tray. In addition, a rotating shaft structure is arranged on the peripheral wall of the barrel for connecting the barrel and the tray, and the tray rotates around the rotating shaft structure. When the stirring device drives the liquid to rotate, the liquid flow drives the driving plate to drive the tray to rotate relative to the barrel around the rotating shaft structure, so that the tray opens the lower port of the barrel. Therefore, compared with the existing automatic unloading assembly, the barrel in this embodiment has no bottom wall structure, does not have the function of supporting materials, and only has the function of accommodating materials, and the materials in the cavity are all supported by the tray. It is precisely because the barrel does not have the function of supporting materials, so when the tray opens the lower port relative to the barrel, the barrel has a larger unloading opening, and the materials in the cavity can fall into the cup body faster. At the same time, when the tray rotates to open the lower port of the barrel, the inner circumferential wall of the barrel will block the material on the tray, so that the material on the tray will be scraped off into the cup body by the inner circumferential wall of the barrel. Therefore, there will be no material residue on the tray. Compared with the existing automatic unloading structure, the unloading assembly of this embodiment can realize the automatic unloading of materials more cleanly. In addition, since the tray rotates around the rotating shaft structure to open the lower port of the barrel, the tray can rotate clockwise with the liquid flow to open the lower port, and can also rotate counterclockwise with the liquid flow to open the lower port. Therefore, the unloading assembly of this embodiment has better versatility and can be applied to food processing machines with different steering motors.

[0056] It should be noted that, for the unloading assembly of this embodiment, the tray can rotate 360° driven by the driving plate, and the driving plate can effectively reduce the problem of slurry splashing and scalding consumers during the rotation process. Moreover, the driving plate can improve the effect of material pulverization while disrupting the rotation of the liquid flow, and the pulverization fineness of the slurry is further improved.

[0057] Generally speaking, in the process of realizing the pulping of food processing machine, the material in the barrel is automatically put into the pulping chamber. The prior art discloses many solutions: using the rotation of water flow to push the driving plate to open the discharge port of the barrel, and the material in the barrel automatically rolls down the pulping chamber under the action of gravity, such as CN201610344153.7 and CN202210854343.9; there is also a driving motor to drive the switch to open the discharge port to realize automatic unloading. However, no matter what kind of automatic unloading structure, the prior art cannot solve the problem of complete unloading of the barrel.

[0058] The present embodiment provides a food processing machine, which has an automatic unloading component, wherein a flushing hole is provided on the peripheral wall of the barrel, and the barrel is arranged in the pulping chamber. When the switch opens the discharge port to discharge the material, the stirring device will drive the liquid flow to rotate at high speed. Since the center line of the barrel is eccentrically arranged relative to the center line of the pulping chamber, the high-speed rotating liquid flow has more opportunities to enter the barrel cavity through the flushing hole, thereby flushing the material adsorbed on the inner wall of the cavity. The material flushed by the liquid flow will fall into the pulping chamber from the discharge port along with the liquid flow, so that the residual material in the barrel can be discharged more thoroughly. It effectively solves the problem of food waste caused by incomplete automatic unloading in the prior art and affects the taste of beverages, and also solves the problem of residual materials being difficult to clean for consumers.

[0059] In order to make it easier for the rotating liquid flow to enter the barrel through the flushing hole, the present embodiment particularly requires that the barrel be eccentrically arranged relative to the pulping chamber. This is because the high-speed rotating liquid flow will rotate and surge along the inner circumferential wall of the pulping chamber when performing centrifugal motion, and a hollow area without liquid flow will be formed in the central area of ​​the pulping chamber. When the barrel is offset relative to the pulping chamber, one side of the barrel will be closer to the inner circumferential wall of the pulping chamber. When the high-speed rotating liquid flow collides with the inner circumferential wall of the pulping chamber, more liquid flow will directly enter or rebound into the flushing hole. Even the liquid flow that rebounds into the barrel will have a certain impact energy, thereby flushing the material adsorbed on the inner circumferential wall of the barrel. The material flushed by the liquid flow will fall into the pulping chamber through the discharge port along with the liquid flow, and participate in the crushing of the material.

[0060] At the same time, the inventors have found through research that when the center line of the barrel is eccentrically arranged relative to the center line of the pulping chamber, two liquid flow areas with one end wide and the other end narrow will be formed between the outer peripheral wall of the barrel and the inner peripheral wall of the pulping chamber, wherein the end with a larger distance between the outer peripheral wall of the barrel and the inner peripheral wall of the pulping chamber is a wide flow area, and the end with a smaller distance is a narrow flow area, and the wide flow area and the narrow flow area are located on the vertical plane P where the center line of the barrel and the center line of the pulping chamber are located, and are located on both sides of the center line of the barrel. If a flushing hole is provided on the peripheral wall of the barrel on one side of the narrow flow area, during the rotation of the stirring device, the liquid in the pulping chamber rotates at high speed with the stirring device, and the liquid flow will surround the outer peripheral wall of the barrel, rotating back and forth between the wide flow area and the narrow flow area. According to the Laval nozzle principle (also known as the Laval nozzle effect), in the process of the liquid flow moving from the wide flow area → the narrow flow area → the wide flow area, a nozzle-like structure is formed, in which the narrow flow area is equivalent to a narrow throat. When the fluid moves in the nozzle, the fluid flow rate increases significantly when passing through the narrow throat with a small cross-section. At the same time, since the scouring hole is arranged on one side of the narrow flow area, the high-speed flowing liquid flow will enter the cavity of the barrel through the scouring hole to flush the material adsorbed on the inner wall of the cavity. Driven by the liquid flow, the material will be flushed into the pulping chamber along with the liquid flow, so as to achieve more thorough material discharge.

[0061] Although CN201610344153.7 also discloses that the side wall of the feeding box is provided with side wall holes, according to the records in the drawings of the patent, the side wall holes are arranged relatively high, and the side wall holes are multiple small circular holes. Moreover, the feeding box is arranged in the center of the cup cover. Therefore, the rotating liquid flow cannot enter the feeding box through the side wall holes, and it is even more impossible to form a flushing of the material in the feeding box (especially the material adsorbed on the inner wall of the feeding box). Obviously, the side wall holes disclosed in the patent are exhaust holes for connecting the cup body and the outside world during pulping, and are used for the purpose of exhausting. Based on the records of the above patent, those skilled in the art cannot think of using high-speed liquid flow to flush the material adhering to the barrel, so as to achieve more thorough material discharge.

[0062] For the unloading assembly of this embodiment, the location of the flushing hole is not limited to the solution disclosed in this embodiment. If the vertical plane where the center line of the barrel and the center line of the pulping chamber are located is defined as plane P, and the vertical plane passing through the center line of the barrel and perpendicular to plane P is defined as plane Q, the flushing hole is preferably set on one side of plane Q and close to the inner wall of the pulping chamber, that is, Figure 3 The left side of the middle plane Q is because this side is more conducive to the high-speed liquid flow entering the barrel through the flushing hole. Of course, flushing holes can also be set on the barrel wall on the right side of the plane Q. Relatively speaking, the liquid flow entering from the right flushing hole is less.

[0063] As mentioned above, for this embodiment, it is more preferable to set the flushing hole near the narrow flow area, or even on the narrow flow area. The inventors have found through research that when the flushing hole is set near the narrow flow area, it is located on the horizontal section where the flushing hole is located, and the angle α formed by the straight line from the flushing hole to the center line of the barrel relative to the plane P generally does not exceed 45°. When it is within 45°, not only is it easier for the liquid flow to enter the barrel, but the impact energy of the liquid flow is also high, which can flush the material adhered to the barrel and achieve the material falling off relative to the barrel; if it exceeds 45°, although the liquid flow can also enter the barrel through the flushing hole, the impact energy of the liquid flow is small, which may not be enough to achieve the material falling off relative to the barrel.

[0064] It should be noted that, in this embodiment, the first magnet disposed on the tray and the second magnet disposed on the peripheral wall of the barrel can assist the tray in closing the lower port of the barrel. Because the shaft structure is disposed on one side of the peripheral wall of the barrel, the tray is prone to warping on the side away from the shaft structure, making it impossible to completely close the lower port of the barrel. The attraction of the first magnet and the second magnet can help solve this problem. Therefore, the attraction force of the first magnet and the second magnet does not need to be too large. Too large an attraction force will make it difficult for the tray to rotate relative to the barrel and open, affecting the effect of automatic unloading. Therefore, precise calculations and selections are required for actual product applications. In addition, the auxiliary closing structure of the tray to the lower port of the barrel is not limited to the magnetic attraction method disclosed in this embodiment, and can also be a clamping structure with a smaller force. For example, a convex point is set on the edge of the tray, and a smaller groove structure is set on the lower edge of the barrel. The convex point is stuck in the groove. Under the strong impact of the liquid flow, the convex point will be separated from the groove. In addition, since the side of the tray away from the shaft structure will be warped downward, after the convex point is separated from the groove, the convex point will not form an obstruction with the groove during the subsequent rotation of the tray. In addition, an elastic sheet can also be set on the tray. Initially, the elastic sheet is against the inner circumferential wall of the barrel. When the liquid flow drives the tray to rotate, the elastic sheet will be separated from the barrel with the tray, so that it will not form an obstruction to the rotation of the tray in the future.

[0065] It should also be noted that, for this embodiment, the barrel includes a material discharge section with a gradually decreasing inner diameter from the discharge port of the barrel upward, so that the barrel as a whole presents a structure with a large lower part and a small upper part. In this way, not only the lower port of the barrel is larger, but also it is beneficial to improve the efficiency and speed of automatic material discharge when the tray opens the lower port of the barrel. Compared with the existing lower cone-shaped barrel structure, the barrel structure of this embodiment can reduce the material remaining in the barrel. Because the barrel has no bottom wall and will not form a supporting effect on the material, even if the material adheres to the inner wall of the barrel, the material will gradually fall off from the inner circumferential wall of the barrel under the action of gravity. Of course, the barrel of this embodiment can also have only a material storage section, from the lower port upward, forming a structure with an inner diameter that changes from large to small. Of course, for this embodiment, the drive plate can be integrally formed on the tray, or it can be detachable relative to the tray, which can be selected according to design needs.

[0066] In this embodiment, the stirring device includes a crushing tool, and when the material falls into the pulping chamber, the crushing tool can crush the material. In addition, the inventor found through research that when the flushing hole set on the peripheral wall of the barrel is a strip hole, when the high-speed rotating liquid flow rushes into the chamber of the barrel from the strip hole, a water surface wall will be formed, so that the material adsorbed on the inner peripheral wall of the barrel can be washed down at one time. In order to better realize the liquid flow entering the barrel, in this embodiment, the strip hole is deflected relative to the center line of the barrel, and is deflected toward the direction of the liquid flow, so that the high-speed rotating liquid flow can enter the barrel more easily along the offset direction of the strip hole, and can also flush the material adsorbed on the peripheral wall of the barrel along the inner peripheral wall of the barrel. Obviously, the direction of the strip hole facing the liquid flow is more conducive to the flushing of the material by the liquid flow, allowing the material to be discharged more thoroughly. Of course, the strip hole can also be set to be inclined relative to the center line of the barrel as needed. At the same time, the inventors have found through research that there are certain requirements for the width of the strip holes. If the strip holes are too narrow, it is difficult for the liquid flow to enter from the strip holes, or even if it can enter the barrel, the impact amount and impact speed of the liquid flow are not enough to flush the material. If the strip holes are too wide, there is a problem that the material is easy to fall from the strip holes into the pulping chamber, especially for small particles such as millet and sesame, and it is impossible to ensure that the accurate amount of material is added each time the pulping is performed. Therefore, the width of the strip holes is generally selected to be 0.4mm to 5mm, and for this embodiment, the strip holes are selected to be 0.5mm to 3mm.

[0067] At the same time, for this embodiment, the upper end of the strip hole is preferably not lower than the height of the pre-stored material in the cavity. If there are more pre-stored materials in the cavity, and the small materials adhering to the inner peripheral wall of the barrel above the strip hole cannot be flushed out, there will still be the problem of residual material discharge. In this embodiment, a water level mark is set on the peripheral wall of the pulping chamber, and the discharge port at the lower end of the barrel is required to be higher than the water level mark to avoid the material being directly immersed in the liquid. Among them, the upper end of the flushing hole is generally required to be no more than 200mm from the height H1 of the water level mark, because if the flushing hole is too high, the liquid flow cannot enter the barrel. Even if it can enter, it cannot be guaranteed that the liquid flow entering from the flushing hole can flush the material adsorbed on the inner peripheral wall of the barrel down. The inventor found through research that under the conditions of the existing food processing machine, as long as H1 does not exceed 200mm, it can basically be achieved that all the materials in the barrel can be flushed down, and the thoroughness of the discharge can be achieved.

[0068] Of course, for this embodiment, the pulping volume V1 of the pulping chamber and the speed n1 of the stirring device also have a certain influence on whether the material can be completely discharged by water flow flushing. The inventor found through research that when V1 / n1=0.02ml / rpm~0.25ml / rpm, the material can basically be completely discharged. When V1 / n1 is less than 0.02ml / rpm, the amount of liquid that impacts the barrel is too small to ensure clean material discharge. If V1 / n1 is greater than 0.25ml / rpm, the liquid surface is relatively stable and it is not easy to form a high-speed liquid flow rotation. At the same time, for this embodiment, R1 is also required to be less than R2 to avoid collision between the driving plate and the spoiler ribs during rotation, causing pulping accidents. Of course, for this embodiment, the driving plate itself also has a spoiler effect. Therefore, spoiler ribs may not be set on the inner peripheral wall of the pulping chamber. When there are no spoiler ribs, it is only necessary that R1 is less than the distance from the center line of the rotating shaft structure to the inner peripheral wall of the pulping chamber, which is also to avoid collision between the driving plate and the inner peripheral wall of the pulping chamber. Of course, even if spoiler ribs are provided on the inner peripheral wall of the pulping chamber, as long as the lower end of the driving plate is higher than the spoiler ribs, it is only necessary that R1 is smaller than the distance from the center line of the shaft structure to the inner peripheral wall of the pulping chamber. In this embodiment, the center line of the shaft structure and the center line of the pulping chamber may not coincide, and even the center line of the barrel, the center line of the shaft structure and the center line of the pulping chamber may not be on the same plane. Regardless of the form in which the barrel is arranged in the pulping chamber, it is necessary to ensure that the driving plate can achieve a stable 360° rotation to avoid collision interference. Of course, while ensuring convenient unloading and no collision of the driving plate, the driving plate may not be required to rotate 360°, and the above-mentioned anti-collision size limitation may not be required.

[0069] It should be noted that, for this embodiment, the barrel is eccentrically arranged relative to the pulping chamber, the main purpose of which is to allow the high-speed rotating liquid flow to have a greater flow rate to rush into the barrel, flush the materials adsorbed in the barrel that are not easy to fall off, and achieve better material discharge. Similarly, a baffle is set on one side of the narrow flow area adjacent to the flushing hole, which is also to block the liquid flow, so that more liquid flow can be rebounded into the barrel through the flushing hole. Therefore, along the rotation direction of the liquid flow, the baffle needs to be located in front of the flushing hole to play the role of blocking the liquid flow and rebounding the liquid flow. For this embodiment, since the drive plate can rotate both clockwise and counterclockwise, the unloading component of this embodiment can be used for food processing machines with different rotation directions of the motor, and the purpose of setting flushing holes on both sides of the baffle is also to improve versatility. No matter which direction the liquid flow rotates, the baffle can block the liquid flow and allow the liquid flow to rebound into the flushing hole. Of course, the baffle is not limited to being arranged on the outer wall of the barrel in the present embodiment, and the baffle may also be arranged on the inner wall of the pulping chamber or the inner wall of the cup cover; or the baffle may be arranged on both the outer wall of the barrel and the inner wall of the pulping chamber.

[0070] In addition, the inventors have found that the width of the narrow flow zone also has a certain influence on the flushing effect of the material in the barrel. If the width of the narrow flow zone is too small, a large amount of liquid will be rebounded by the narrow flow zone, and thus cannot pass through the narrow flow zone, and the liquid entering the flushing hole will be less. If the width of the narrow flow zone is too large, the impact speed or impact energy of the liquid will also be affected. Even if there is liquid entering the barrel, the impact force is not large, and the adsorbed material cannot be flushed down. The inventors have found through repeated research that the average radial width N of the narrow flow zone is controlled at 5mm to 40mm, which can achieve thorough material discharge.

[0071] It should be noted that the barrel and pulping chamber in this embodiment are generally regular shapes, and the center line of the barrel and the center line of the pulping chamber are the center lines of the horizontal cross sections of the barrel and the pulping chamber. The above structural changes and parameter selections of this embodiment can also be applied to other embodiments of the present invention.

[0072] Embodiment 2:

[0073] like Figure 6 , Figure 7 , Figure 8, which is a schematic diagram of the structure of another embodiment of the blanking assembly of the present invention. The difference between this embodiment and the first embodiment is that: a protrusion 317 is provided on the inner side of the peripheral wall of the barrel 31 and along the axial direction, and the rotating shaft structure includes an axis groove 342 provided on the protrusion 317 and a rotating shaft 343 provided on the tray 32, and the rotating shaft 343 is installed in the axis groove 342, and the rotating shaft 343 is located in the axis groove 342 and rotates. Among them, the rotating shaft 343 is integrally formed on the upper surface of the tray 32, and a recessed portion 3431 is provided in the middle of the rotating shaft 343, and, located on one side of the lower end of the barrel 31, a first opening 3171 is provided at the bottom of the protrusion 317 to communicate with the axis groove 342, and located on the outer peripheral wall of the barrel 31, the protrusion 317 has a second opening 3172 to communicate with the axis groove 342. Among them, a protrusion 3421 corresponding to the recessed portion 3431 of the rotating shaft 343 is provided in the shaft groove 342, and the rotating shaft 343 is inserted into the shaft groove 342 through the first opening 3171, and the protrusion 3421 and the recessed portion 3431 are engaged with each other to form an axial limiting structure of the rotating shaft 343 and the shaft groove 342, so that the rotating shaft 343 is not easy to fall out of the shaft groove 342. At the same time, the above structure also makes it easy to realize the removal of the rotating shaft 343 and the tray 32 from the barrel 31.

[0074] For this embodiment, the shaft structure is set as the installation method of the shaft and the shaft groove, which is more conducive to the detachability of the shaft and the shaft groove, and can be convenient for users to disassemble and clean by themselves, preventing the dead corners of the shaft structure from being effectively cleaned for a long time and causing odor, and even food safety and sanitation problems. Of course, the shaft structure of this embodiment is not limited to the installation method of the shaft and the shaft groove, and similarly, the detachable method of the tray relative to the barrel is not limited to the solution disclosed in this embodiment.

[0075] It should be noted that the above structure and its variations of this embodiment may also be applicable to other embodiments of the present invention.

[0076] Embodiment three:

[0077] like Fig. 9 , Fig.10 As shown in FIG. 1 , another structure of the blanking assembly of the present invention is shown. This embodiment is an improvement based on the second embodiment. The difference between this embodiment and the second embodiment is that the installation structure of the rotating shaft 343 and the shaft groove 342 is different. Among them, the shaft groove 342 extends along the axial direction of the barrel 31 to the lower end of the barrel 31, and an open end 3100 is formed on the peripheral wall of the barrel 31, and the rotating shaft 343 is transversely inserted into the shaft groove 342 from the open end 3100. At the same time, the positioning pin a passes through the protrusion 317 from the barrel 31 and is inserted into the rotating shaft 343, so that the rotating shaft 343 is positioned on the protrusion 317, and the rotating shaft 343 is not easy to escape from the shaft groove 342 from the open end 3100.

[0078] This embodiment is the same as the second embodiment. The tray and the rotating shaft can be removed from the barrel together, which is convenient for consumers to clean and is not prone to the problem of cleaning dead corners. At the same time, the structure of the first embodiment can also be applied to this embodiment, using water flushing to achieve more thorough material discharge.

[0079] It should be noted that the unloading assembly used in the food processing machine of the present invention is not limited to the scheme disclosed in the embodiment of the present invention. For example, the switch member is driven to move by the driving plate, which is not limited to the liquid flow driving the driving plate to rotate disclosed in the embodiment of the present invention, wherein the driving plate can also realize the switch member opening the discharge port of the barrel in a translational manner. Even for the scheme in which the driving plate drives the switch member to rotate and open the discharge port, it is not limited to the rotating shaft structure disclosed in the embodiment of the present invention being arranged on the peripheral wall of the barrel, and the rotating shaft structure can also be arranged at the bottom center of the barrel, in which case the bottom of the barrel is not open. Of course, for the food processing machine of the present invention, even the bottom of the switch member does not need to be provided with a driving plate driven by the liquid flow, and it only needs to use other driving means (such as motor drive, manual) to open the discharge port, and realize the process of unloading, and use the rotating liquid flow to flush the material into the barrel through the flushing hole to flush the material, so as to realize the automatic discharge of the material.

[0080] It should also be noted that the food processor of the present invention can be a wall-breaking machine with a cup body and a machine base separated, or a motor-mounted soymilk machine with a machine head mounted on the cup body, or a motor-mounted soymilk machine with a motor and a cup body mounted as one, or even a food processor with a machine body and a pulping chamber disposed in the machine body that does not need to be washed by hand, wherein the solution in which the material discharge component is disposed in the pulping chamber is not limited to being installed on the cup cover, and the material discharge component can also be directly installed in the cup body through a mounting structure, or installed on the machine head. In order to facilitate the user to clean the material discharge component, a detachable mounting method of the material discharge component from the food processor can also be provided.
