Background

The present assignee applied a chinese utility model patent with patent number "CN 201420254147.9" and title "an easily cleaned non-pressure soymilk machine". This patent specification discloses that an overflow preventing cover having an air vent is provided to a small-space pulverizer, and an arc-shaped overflow preventing reserve space that protrudes upward is formed toward the edge of the overflow preventing cover with the air vent as the center. Because the arc-shaped anti-overflow reserved space is formed around the air vent of the anti-overflow cover, when the crushing blade pulls the slurry upwards, the slurry is prevented from overflowing outwards through the air vent to the maximum extent.

The inventor of the present invention conducted research and analysis based on the structure of the above patent, and found that the structure can solve the problem of slurry overflow, or more precisely, the problem of slurry foam or foam overflow well. It will be apparent to those skilled in the art that the slurry comprises a pure liquid slurry and a slurry froth at the surface of the pure liquid slurry. Because the air in the small-space shredder is mixed with the pure liquid slurry when the crushing blade draws the slurry upward, the slurry after partially mixing the air forms slurry foam or froth, and, because the pulp foam or froth mixed with air is light, it floats on the surface of the pure liquid pulp, and this results in more foam or froth on the surface of the pure liquid pulp, especially when the pulp is still in the raw or uncooked stage, because the liquid raw slurry has high molecular viscosity and is not easy to break after containing gas, the slurry foam on the surface of the pure liquid slurry is more and even reaches the thickness of 2 cm-4 cm, the slurry foam can be lifted by the pure liquid slurry below and moves to the anti-overflow reserved space, because the anti-overflow headspace has the function of holding and slowing down thick liquid foam and moving towards the air vent to the effectual risk that thick liquid foam spills out and overflows through the air vent that has reduced. However, the soymilk machine of the above patent cannot be automatically cleaned, manual intervention is required for cleaning, the cleaning is inconvenient, and when the crushing blade pumps the soymilk upwards, since the vent hole is positioned right above the crushing blade, the soymilk may be splashed to the outside of the soymilk machine through the vent hole, so that the risk of scalding a user exists.

Detailed Description

The first embodiment is as follows:

fig. 1 and fig. 2 are schematic structural diagrams of a first embodiment of the present invention. The utility model provides a food processor, includes that little space smashes cup 1, installs in the terminal crushing blade 2 of pivot 41 and the bowl cover 3 of lid in little space crushing cup 1 top, pivot 41 is driven by motor (not drawn in the picture), and smashes blade 2 and be located in the crushing chamber 10 that little space crushing cup 1 formed, be provided with the sealing member 5 of sealed cooperation department between little space crushing cup 1 and the bowl cover 3, little space crushing cup 1 volume V1 is not more than 1000mL, bowl cover 3 bottom is formed with the supplementary chamber 30 of upwards sunken, supplementary chamber 30 surrounds with crushing chamber 10 and forms flourishing thick liquid container, and during food processor during operation, liquid in the little space crushing cup 1 gushes into supplementary chamber 30 on the chamber wall of crushing chamber 10, wherein, the volume V2 of supplementary chamber 30 is not less than 100 mL.

In this embodiment, the rotation plane of the crushing blade 2 is perpendicular to the central axis of the small space crushing cup 1, the auxiliary chamber 30 includes a vertically extending peripheral wall 301 and a top wall 302 which is connected with the peripheral wall into a whole and is transversely disposed, and the crushing blade 2 has a pressing part which drives the slurry to move towards the bottom of the small space crushing cup 1, wherein the pressing part is a blade surface 22 which is disposed on the blade 21 of the crushing blade and faces one side of the bottom of the small space crushing cup 1.

In this embodiment, because flourishing thick liquid container surrounds the formation by the crushing chamber that the cup formed is smashed to the little space and the supplementary chamber that the bowl cover formed, and smashes the cooperation department sealing connection in chamber and supplementary chamber, consequently, slurrying and washing all can go on automatically in this flourishing thick liquid container, need not manual intervention, and the operation is safer and convenient.

In the abluent in-process of food preparation machine, when smashing the high-speed rotation of blade, can drive the high-speed rotation of the washing liquid in the small space crushing cup, because the volume V1 of small space crushing cup is not more than 1000mL, compare in the soybean milk machine cup volume among the prior art and need little much, therefore, the loss that the washing liquid of high-speed rotation received the shear resistance of molecule between the liquid also needs little much, the kinetic energy that washing liquid gushed on the wall of cup along the small space crushing cup is corresponding great, thereby can enter into the auxiliary chamber through the rim of a cup, at this in-process, because kinetic energy loss and the effect of converging that the small space crushing cup can effectual reduction liquid stream, make the washing liquid can wash the whole wall of cup of small space crushing cup, compare in prior art, the self-cleaning of whole cup has been realized. Meanwhile, the volume V2 of the auxiliary cavity is not less than 100mL, so that the auxiliary cavity can contain more cleaning liquid to enter the auxiliary cavity in the cleaning process, and the cleaning liquid entering the auxiliary cavity flows back to the bottom of the small-space grinding cup along the wall of the small-space grinding cup under the action of gravity, so that the whole wall of the cup is washed twice, and the food processor is ensured to be automatically cleaned after repeated circulation. Moreover, the inventor discovers through research that when the volume V1 is not more than 800mL, the cleaning liquid basically can be flushed up to the auxiliary cavity, and when the volume V2 is not more than 150mL, the cleaning liquid which is flushed up to the auxiliary cavity is more, so that the secondary flushing effect on the whole cup wall is better, the cup can be cleaned after being circulated for a plurality of times, and the time for automatic cleaning is greatly reduced.

In the process of preparing the milk by the food processing machine, because the crushing chamber volume V1 that the cup formed is smashed to the little space is not more than 1000mL, material and thick liquid can smash the cup formation in the little space of relative narrowness and concentrate and smash, crushing efficiency is very high, and crushing blade has the portion of pushing down that drives the thick liquid and smash the cup bottom motion towards the little space, can rebound near crushing blade more easily after the material collision cup diapire or perisporium of downstream, thereby increased the probability that the material is smashed the blade collision, great promotion the crushing efficiency of material. For the food processing machine of the embodiment, the prepared soybean milk beverage can be filtered by 50 meshes without residues, and the drinking taste of consumers is greatly improved. In addition, although the food processor of the present embodiment is configured such that the crushing blade rotates at a high speed to centrifugally rotate the slurry at a high speed, and the slurry rotating at a high speed collides with the wall of the small space crushing cup to cause the splash or splash phenomenon, in the present embodiment, the crushing blade has a pressing portion for driving the slurry toward the bottom of the small space crushing cup, and the slurry moving downward collides with the bottom wall of the small space crushing cup to upwardly flow along the peripheral wall of the small space crushing cup, so that the probability of the splash phenomenon is greatly reduced, and the volume V2 of the auxiliary chamber of the present embodiment is not less than 100mL, and the crushing chamber and the auxiliary chamber are sealingly engaged with each other, so that the splashed or splashed slurry is confined in the auxiliary chamber of a relatively large space under the action of gravity even if the splash or splash phenomenon occurs, and the speed of splashing or splashing can also weaken gradually, even there is thick liquid blowout flourishing thick liquid container outside, also great reduction thick liquid spun distance, further reduced the risk that the user is scalded.

It should be noted that, for this embodiment, the turbulence ribs can be arranged on the peripheral wall of the small-space crushing cup, so as to increase the turbulence effect of the slurry flow and correspondingly improve the efficiency of cutting the material. Of course, for the present embodiment, there are various forms for increasing the fineness of the crushed material, and the inventor finds, according to research, that increasing the load rotation speed of the motor can also increase the crushing efficiency of the food processor of the present embodiment, and for the present embodiment, the load rotation speed of the motor is generally required to be 8000r/min to 20000r/min, wherein the load rotation speed of the motor is preferably 12000r/min to 18000 r/min. Or the bottom of the small-space crushing cup is provided with the contraction part which contracts inwards, and the crushing blade is arranged in the contraction part, so that the crushing fineness of the material can be greatly improved by centralized crushing in a smaller space.

It should be noted that, for the present embodiment, the volume V1 of the small-space pulverizing cup is preferably not more than 800mL, and the volume V2 of the auxiliary chamber is preferably not less than 150 mL. Because the smaller the volume V1 of the small-space crushing cup, the better the efficiency of the concentrated crushing of the material, and at the same time, the volume V2 of the corresponding auxiliary chamber also needs to be increased correspondingly, so that more washing liquid can be contained and the phenomenon that the food processor is splashed to hurt people can be prevented. The inventor finds that the volume V of the pulp container formed by the surrounding of the crushing cavity and the auxiliary cavity is generally required to be 1000-1800 mL, and the auxiliary cavity is sunken upwards to form the volume V of the pulp container to be more than 1000mL when the volume of the pulp container is ensured to be less than 1000 mL. Because, if the pulp container V formed by encircling is less than 1000mL, although the fineness of the crushed pulp can be well guaranteed, when the crushing blade rotates at a high speed, the smoothness of the surface of the pulp liquid tends to become severe, and the splashing degree also tends to become severe, so that the risk of scalding users tends to increase, and potential safety hazards exist. On the contrary, if V is greater than 1800mL, while guaranteeing the material crushing fineness, the phenomenon of splashing can not occur any more basically, but at this moment, the volume of the auxiliary chamber is excessively large, which causes the waste of the space of the auxiliary chamber, and meanwhile, the product is too fat in shape and not beautiful enough, and if the volume of the auxiliary chamber is reduced, the volume of the small-space crushing cup is required to be increased correspondingly, which causes the material crushing degree to be unable to reach, and when cleaning the small-space crushing cup, because the height of the small-space crushing cup is too large, the cleaning liquid can not flow up to the auxiliary chamber, and the automatic cleaning of the whole small-space crushing cup can not be realized. Therefore, the volume of the pulp container is more than 1000mL and less than or equal to 1800mL as much as possible. For the present embodiment, the volume V of the slurry container is preferably 1100mL to 1600mL, and for the same reason as above, the ratio of V2/V1 is 1/8 to 1, for example, the volume V1 of the small space pulverizing cup is 700mL, and the volume V2 of the auxiliary chamber is 500 mL.

In addition, it should be noted that, for this embodiment, when the food processor is cleaned, the crushing blade rotates at a high speed, and the cleaning liquid can flow up to the auxiliary cavity along the wall of the cup, so that the small-space crushing cup can be automatically cleaned without being disassembled. The inventor finds that when the ratio of the distance H1 from the plane of the blade root of the crushing blade to the cup mouth of the small-space crushing cup to the depth H2 of the small-space crushing cup is 0.6-0.9, the cleaning liquid can be enabled to flow upwards into the auxiliary cavity when the crushing blade rotates at a high speed. And when being less than 0.6, although the cleaning fluid can all be gushed up to the rim of a cup, but this moment, cleaning fluid must not cross crushing blade, and the washing quantity is great, exists extravagantly probably, and if be greater than 0.9, then crushing blade is located the nearly bottom of a cup in little space crushing cup, because the clearance of crushing blade and little space crushing cup bottom of a cup reduces, along the cup wall kinetic energy that the cleaning fluid who rushes up reduces, probably there is unable gushes up to the auxiliary chamber, the unable abluent possibility in the rim of a cup near that has little space crushing cup. Therefore, for the present embodiment, H1/H2 is preferably 0.7-0.85. Of course, the inventor finds out through research that on the basis of the embodiment, if the rotation plane of the crushing blade is parallel to the central axis of the small-space crushing cup, the cleaning liquid can flow up the cup wall to the auxiliary cavity, and the whole small-space crushing cup can be automatically cleaned. Alternatively, in this embodiment, the crushing blade has no pressing part, or the pressing part is a blade twisted with respect to the blade root plane on the crushing blade, so that the small-space crushing cup can be automatically cleaned.

It should be noted that the above structural transformation and parameter selection of the present embodiment can also be applied to other embodiments of the present invention.

Example two:

fig. 3 and 4 are schematic structural diagrams of a second embodiment of the present invention. In this embodiment, the food processor comprises a base 6, the small-space pulverizing cup 1 is fixed in the base 6, one end of the cup cover 3 is hinged and fixed (not shown in the figure) with the base 6, the cup cover 3 can be opened by rotating around the hinged part relative to the small-space pulverizing cup 1, and the cup cover 3 can be detached from the base 6.

In addition, be provided with on the roof in supplementary chamber to supplementary intracavity bellied exhaust passage 31, exhaust passage 31 and outside atmosphere intercommunication, and exhaust passage 31's the outside is big-end-up's loudspeaker column structure down, still be provided with the annular flat plate 32 of outside extension on the periphery wall of bowl cover 3, the annular flat plate 32 is level with the top of base mutually for whole more pleasing to the eye, and the cup lid portion more than the annular flat plate 32 at least is transparent or translucent state, in order to make things convenient for the user to observe slurrying and cleaning process.

In this embodiment, after motor speed is greater than 12000r/min, when smashing the high-speed rotation of blade, the washing liquid speed of surging on the wall of cup along little space crushing cup is very fast, probably can dash the roof in supplementary chamber, and surging to the bowl cover center along the roof, because in this embodiment, exhaust passage's the outside is big-end-up's horn-shaped structure down, when the washing liquid who upwells touches exhaust passage's external profile, can lead to on the perisporium of little space crushing cup along exhaust passage's horn-shaped, thereby the washing liquid who upwelles on the realization erodees the wall of cup, realize the secondary and wash, and, after recycling, finally realize whole little space crushing cup sanitization.

It should be noted that the above structural changes to the present embodiment can also be applied to other embodiments of the present invention.

Example three:

fig. 5 is a schematic structural diagram of a third embodiment of the present invention. The present embodiment is different from the second embodiment in that: in this embodiment, the top wall of the auxiliary cavity is provided with an exhaust through hole 33, and an exhaust cover 34 is installed on the exhaust through hole 33, the exhaust cover 34 is provided with an exhaust column 35 which extends into the exhaust through hole 33 and is hollow, and an exhaust port 36 communicated with the external atmosphere is arranged on the peripheral wall of the exhaust column 35, so that the gas in the slurry container can be exhausted to the external atmosphere through the hollow exhaust column 35 and the exhaust port 36, and the matching part of the small-space crushing cup and the cup cover is sealed, therefore, even if the crushing blade is used for high-speed pulping, the slurry forming splashing is not easy to directly splash out of the food processor through the exhaust column 35 and the exhaust port 36, and therefore, the potential safety hazard of users due to the splashing of the slurry can be basically and completely avoided.

In addition, in this embodiment, the peripheral wall of the auxiliary cavity is inclined relative to the horizontal plane, and the inclined auxiliary cavity wall has a blocking effect on upwelling cleaning liquid, so that the upwelling cleaning liquid is reduced in speed and is easier to flow back along the cup wall to repeatedly wash the cup wall.

It should be noted that the structural change of the present embodiment can be applied to other embodiments of the present invention.

In the present invention, the food processor is a food processor capable of producing liquid beverages such as soybean milk.
