Therefore, how to design a food processing device that overcomes the above technical drawbacks is a technical problem that needs to be solved.

The application defines a food processing device, after food materials are placed in the food processing device, corresponding food can be generated through fermentation reaction, and particularly, the food materials and liquid can be mixed, and a required drink can be obtained after fermentation is completed. In particular, the food processing apparatus includes a body, which is a main body frame structure of the food processing apparatus, for positioning and supporting other structures on the food processing apparatus. The fermentation cavity is formed inside the body and is used for containing food materials and liquid, after the food materials and the liquid are put into the fermentation cavity, fermentation bacteria contained in the food materials produce fermentation reaction, so that substances beneficial to the flavor of the beverage are generated, and food meeting the demands of users is obtained. For example, after milk and lactic acid bacteria are placed in the fermentation chamber, yogurt can be obtained after fermentation for a predetermined period of time, or grain wine and fruit wine can be obtained by fermentation reaction after grains, fruits and water are placed in the fermentation chamber.

Wherein, still be provided with temperature regulation subassembly on the body, temperature regulation subassembly is used for adjusting the temperature of fermentation chamber.

Wherein, different food materials correspond different fermentation proper temperatures, set up adjustable temperature regulation subassembly and help promoting food treatment facility's application scope.

In the related art, oxygen exists in a cavity of a device for brewing fruit wine or preparing yoghurt, after food materials and water are put into the device, the food materials inevitably contact with the oxygen in the cavity and generate oxidation reaction, gaps among the device structures are difficult to be sealed absolutely, and oxygen outside the device leaks into the cavity and aggravates the oxidation reaction. On one hand, the food material may generate impurities and bacteria, such as methanol, which are harmful to the health of the user during the aerobic fermentation. And the microbial content of the aerobically fermented liquid may exceed the food safety level. After a user drinks a drink containing fusogenic bacteria or microorganisms exceeding the standard, the physical health of the user is affected, and reactions such as food poisoning and the like occur. On the other hand, the food materials subjected to aerobic fermentation can generate colored substances dissolved in the liquid, the colored substances can brown the beverage, the beverage with changed color can cause wrong judgment for a user, the beverage which is not completely fermented is drunk by mistake, the appearance of the beverage can be influenced, and the use experience of the user is reduced.

In this regard, the present application provides a filter and drive assembly on a food processing apparatus. In particular, the filter element is arranged inside the fermentation chamber.

Wherein liquid can pass through the filter element, and solid food material can be blocked by the filter element. During operation, after the food material and liquid are poured into the fermentation chamber, a portion of the food material may float at the liquid level or be suspended in the liquid.

The filter element is driven to move downwards through the driving component, so that food materials can be gradually compressed in the space at the bottom of the fermentation cavity, and part of liquid at the bottom of the fermentation cavity is extruded into the space above the filter element. Under the condition, the liquid above the filtering piece can play a role in sealing so as to prevent oxygen above the liquid level from contacting the food material and carrying out oxidation fermentation reaction with the food material, thereby solving the technical problems that the food material is easy to produce mixed bacteria and mixed alcohol in the oxidation fermentation process and the liquid is dyed by substances separated out by the oxidation fermentation reaction of the food material to produce brown stain, and obtaining the drink with excellent quality and gorgeous color. Meanwhile, the driving component drives the filter piece to reciprocate up and down, so that the food material and the liquid can be stirred on the basis of ensuring that the food material is not contacted with oxygen, and the saccharomycetes, the food material and the liquid are uniformly mixed, so that on one hand, the precipitation rate of beneficial flavor substances in the food material can be accelerated, and on the other hand, the fermentation speed of the food material can be accelerated. In addition, after the preparation of drink is accomplished, controllable drive assembly drives the filter and sticis food material downwards, makes the liquid that contains in the food material be pressed out on the one hand, on the other hand can avoid food material to mix in the drink of pouring out through the barrier effect of filter.

On the basis, the stirring capability of the filter element can be enhanced by driving the filter element to rotate in the fermentation cavity through the driving component. In particular, the filter element rotating within the fermentation chamber may act like an impeller, causing the liquid and food material to move continuously under agitation of the filter element, e.g., the liquid and food material to spin helically within the fermentation chamber. Therefore, the food material and the liquid are fully mixed, the precipitation rate of the substances with favorable flavor in the food material is further accelerated, the fermentation rate is improved, and the time consumption of waiting for the finished beverage by a user is reduced.

It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

Food processing apparatus according to some embodiments of the present application are described below with reference to fig. 1 to 15.

Example 1

As shown in fig. 1, 3 and 4, a first aspect of the present application provides a food processing apparatus 100, the food processing apparatus 100 comprising: a body 110 including a fermentation cavity 112; the temperature adjusting component is arranged on the body and used for adjusting the temperature of the fermentation cavity; a filter 120 disposed in the fermentation chamber 112; the driving assembly 130 is provided on the body 110 and connected to the filter 120, and is capable of driving the filter 120 to move in the height direction of the food processing apparatus 100 and/or driving the filter 120 to rotate.

The present application defines a food processing device 100, in which food materials can be produced into corresponding food products through a fermentation reaction after being placed in the food processing device 100, and in particular, the food materials and liquid can be mixed to obtain a desired beverage after fermentation is completed. Specifically, the food processing device 100 includes a body 110, the body 110 being a main body frame structure of the food processing device 100 for positioning and supporting other structures on the food processing device 100. The fermentation cavity 112 is formed inside the body 110, the fermentation cavity 112 is used for containing food and liquid, and after the food and liquid are put into the fermentation cavity 112, fermentation reaction is generated by fermentation bacteria contained in the food to generate substances beneficial to the flavor of the beverage, so that food meeting the demands of users is obtained. For example, after milk and lactic acid bacteria are placed inside the fermentation chamber 112, yogurt can be obtained after fermentation for a predetermined period of time, or grain wine and fruit wine can be obtained by fermentation reaction after grains, fruits and water are placed inside the fermentation chamber 112.

Wherein, the body 110 is further provided with a temperature adjusting assembly 150, and the temperature adjusting assembly 150 is used for adjusting the temperature of the fermentation cavity 112. The temperature adjustment assembly 150 may include an electric heating element to heat the fermentation chamber 112 by contact, and the temperature adjustment assembly 150 may also include an electromagnetic heating element to heat the cup 114 by an electromagnetic field. The temperature adjusting assembly 150 may further include a refrigerant heat exchange system to heat or cool the fermentation cavity 112 by a refrigerant, so that the specific structure of the temperature adjusting assembly 150 is not rigidly limited, and the temperature adjusting assembly 150 is set to adjust the temperature in the fermentation cavity 112 to a temperature suitable for fermentation reaction of fermentation bacteria, thereby improving fermentation efficiency and shortening waiting time of a user.

Wherein, different food materials correspond to different proper fermentation temperatures, and the adjustable temperature adjusting assembly 150 is provided to help to improve the application range of the food processing apparatus 100.

In this regard, the present application provides the filter 120 and the drive assembly 130 on the food processing apparatus 100. Specifically, the filter 120 is disposed inside the fermentation chamber 112. After the assembly of the filter 120 is completed, the filter 120 can define the solid food material under the filter 120. The driving assembly 130 is mounted on the body 110, and the driving end of the driving assembly is connected with the filter element 120, so that the filter element 120 can be driven to move in the height direction of the food processing equipment 100, and meanwhile, the driving assembly 130 can also drive the filter element 120 to rotate in the fermentation cavity 112. Wherein liquid may pass through the filter 120, solid food material may be blocked by the filter 120. During operation, after the food material and liquid are poured into the fermentation chamber 112, a portion of the food material may float at the liquid level or be suspended in the liquid.

The filter 120 is driven to move downwards by the driving component 130, so that the food materials can be gradually compressed in the space at the bottom of the fermentation cavity 112, and part of liquid at the bottom of the fermentation cavity 112 is extruded into the space above the filter 120. In this case, the liquid above the filter 120 can play a sealing role to prevent oxygen above the liquid level from contacting the food material and performing an oxidative fermentation reaction with the food material, so as to solve the technical problems that the food material is easy to generate mixed bacteria and mixed alcohol in the oxidative fermentation process, and the liquid is dyed by the substances separated out by the oxidative fermentation reaction of the food material to generate brown stain, so that the beverage with excellent quality and bright color is obtained. Meanwhile, the filter 120 is driven to reciprocate up and down by the driving component 130, so that the food material and the liquid can be stirred on the basis of ensuring that the food material is not contacted with oxygen, and the saccharomycetes, the food material and the liquid are uniformly mixed, so that on one hand, the precipitation rate of the beneficial flavor substances in the food material can be accelerated, and on the other hand, the fermentation speed of the food material can be accelerated. In addition, after the beverage is prepared, the driving assembly 130 can be controlled to drive the filter 120 to press the food material downwards, so that on one hand, the liquid contained in the food material is pressed out, and on the other hand, the food material can be prevented from being mixed in the poured beverage through the blocking effect of the filter 120.

On this basis, the stirring capability of the filter 120 can be enhanced by driving the filter 120 to rotate in the fermentation chamber 112 by the driving assembly 130. Specifically, the filter 120 rotating within the fermentation chamber 112 may act like an impeller, causing the liquid and food material to move continuously under agitation of the filter 120, e.g., the liquid and food material to spin within the fermentation chamber 112. Therefore, the food material and the liquid are fully mixed, the precipitation rate of the substances with favorable flavor in the food material is further accelerated, the fermentation rate is improved, and the time consumption of waiting for the finished beverage by a user is reduced. And then the structure of the food processing equipment 100 is optimized, the oxidation fermentation reaction of food materials is inhibited, the anaerobic fermentation rate of the food materials is improved, the quality and the safety of the obtained beverage are improved, and the technical effect of using experience of users is improved.

In this embodiment, the structure of the driving assembly 130 will be described. Specifically, the drive assembly 130 includes a drive 132 and a transmission 134. The driving member 132 is mounted on the body 110, and a power input end of the transmission mechanism 134 is connected with a power output end of the driving member 132, and a power output end of the transmission mechanism 134 is connected with the filtering member 120 to drive the filtering member 120 to lift in a height direction of the food processing apparatus 100 and drive the filtering member 120 to rotate in the fermentation cavity 112. The number of driving members 132 and the form of the transmission mechanism 134 are not limited rigidly, and the filter member 120 can be driven to rotate and move up and down by different driving members 132, and the filter member 120 can be driven to move and rotate simultaneously by a single driving member 132.

In this embodiment, the structure of the transmission mechanism 134 is described. Specifically, the transmission mechanism 134 includes a guide 1341 and a first link 1343. The guide member 1341 is positioned and installed on the body 110 between the driving member 132 and the filter member 120, and is located inside the fermenting chamber 112, and extends from the body 110 toward the depth direction of the fermenting chamber 112. The guide 1341 is provided with a through hole penetrating the guide 1341 in the height direction of the food processing apparatus 100, and opposite ends of the through hole are respectively opposite to the driving part 132 and the filter 120. The bottom end of the first link 1343 is fixedly connected with the filter 120, and the top end penetrates through the through hole and is connected with the driving member 132. In operation, the first link 1343 may drive the filter member 120 to move up and down along the axial direction of the through hole, i.e., up and down in the height direction of the food processing apparatus 100, under the driving of the driving member 132. At the same time, the driving member 132 can also drive the first link 1343 to rotate in the guide member 1341, and the rotation axis of the first link 1343 coincides with the axis of the through hole, so that the filter 120 connected to the first link 1343 can rotate while being lifted and lowered, thereby enhancing the stirring performance of the filter 120. By providing the guide member 1341, the movement direction of the first link 1343 and the filter element 120 can be guided accurately, so that the filter element 120 is prevented from losing its filtering capability due to the deflection movement, and the probability of the transmission mechanism 134 getting stuck is reduced. At the same time, the provision of nested guides 1341 and first links 1343 helps to promote the compactness of the drive mechanism 134, thereby reducing the space occupied by the drive mechanism 134 by the fermentation chamber 112 while meeting the driving requirements of the filter 120. Thereby realizing the technical effects of optimizing the structure of the transmission mechanism 134, improving the transmission stability and transmission precision of the driving structure and providing convenience for the miniaturized design of the food processing equipment 100.

As shown in fig. 8 and 9, an inner wall of the through hole is provided with female screw 1342, and a peripheral side wall of the first link 1343 is provided with male screw 1345 which is identical to the female screw 1342.

In this embodiment, a configuration of engagement between the guide 1341 and the first link 1343 is defined. Specifically, the guide member 1341 is provided with female threads 1342 on an inner wall, i.e., a through hole, and correspondingly, the first link 1343 is provided with male threads 1345 on a peripheral side wall thereof, which are adapted to the female threads 1342. In operation, the driving member 132 drives the first link 1343 to rotate in the through hole, and the driving member 132 moves toward the top or bottom of the fermenting chamber 112 during rotation by the engagement of the internal and external threads 1345. Wherein, the control driving member 132 is reversed to complete the turning of the up-down movement direction of the first link 1343. The screw transmission structure has the advantages of high transmission precision, high stability and high reliability, and the internal and external screw threads 1345 are respectively arranged on the through hole and the first connecting rod 1343, so that on one hand, the motion precision and the reliability of the filter 120 can be improved, and on the other hand, the noise generated in the lifting and rotating processes of the filter 120 can be reduced. And further, the structure of the transmission mechanism 134 is optimized, the transmission reliability and stability are improved, and the technical effect of user experience is improved.

The first link 1343 includes an axially extending first locating hole, and the drive mechanism 134 further includes: a second link 1346 having one end connected to the driving member 132 and the other end penetrating the first positioning hole and slidably connected to the first link 1343.

In this embodiment, a first positioning hole extending in the axial direction is further provided in the first link 1343, and the extending direction of the first positioning hole is identical to the extending direction of the through hole. On the basis, a second connecting rod 1346 is further arranged in the transmission mechanism 134, the outer diameter of the second connecting rod 1346 is smaller than the diameter of the first positioning hole, one end of the second connecting rod 1346 is connected with the power output shaft of the driving piece 132 through a coupling, the other end of the second connecting rod is inserted into the first positioning hole and is in sliding connection with the first connecting rod 1343, and the sliding direction of the sliding connection is the axial direction of the first positioning hole. In operation, the driving member 132 drives the second link 1346 to rotate, and the rotating second link 1346 drives the first link 1343 to rotate synchronously, so that the rotating first link 1343 ascends or descends along the axis of the through hole under the cooperation of the internal thread 1342 and the external thread 1345. Wherein the length of the second link 1346 inserted into the first positioning hole is gradually increased during the ascending of the first link 1343 and the filter 120, whereas the length of the second link 1346 inserted into the first positioning hole is gradually decreased during the descending of the first link 1343 and the filter 120. By providing the first positioning hole and the second connecting rod 1346, the first connecting rod 1343 can be precisely positioned, the internal and external threads 1345 are ensured to be engaged, and the first connecting rod 1343 is prevented from moving obliquely in the through hole. And the nested structure can further improve the compactness of the structure on the basis of meeting the demands of rotation and up-and-down motion, and reduces the space occupied by the transmission mechanism 134 in the fermentation cavity 112. And further, the structure of the transmission mechanism 134 is optimized, the movement precision and the movement stability of the filter 120 are improved, the failure rate of the transmission mechanism 134 is reduced, and the technical effect of providing convenience for the miniaturized design of the food processing equipment 100 is achieved.

As shown in fig. 10 and 11, the transmission mechanism 134 further includes: a guide groove 1344 provided on the first link 1343, located in the first positioning hole, and extending in the axial direction of the through hole; a slider 1347 connected to the second link 1346 and slidable on the guide groove 1344.

In this embodiment, the sliding connection structure of the first link 1343 and the second link 1346 is further defined as the above-described embodiment. Specifically, a guide groove 1344 is provided on the first link 1343, the guide groove 1344 is provided on the inner wall of the first positioning hole, and the guide groove 1344 extends in the axial direction of the through hole. Correspondingly, a sliding block 1347 is sleeved on the second connecting rod 1346, the sliding block 1347 is fixedly connected with the second connecting rod 1346, and the sliding block 1347 is driven to synchronously rotate when the second connecting rod 1346 rotates. Wherein the outer profile of the slide 1347 matches the guide slot 1344, and at least a portion of the slide 1347 is positioned within the guide slot 1344 after assembly of the drive mechanism 134 is completed. When the driving piece 132 works, the second connecting rod 1346 and the sliding block 1347 are driven to rotate, the sliding block 1347 positioned in the guiding groove 1344 pushes the first connecting rod 1343 to synchronously rotate, so that the external thread 1345 on the first connecting rod can move in the internal thread 1342 on the through hole, and the sliding block 1347 slides on the guiding groove 1344 in the moving process. By providing the guide groove 1344 and the slider 1347, an axial sliding connection of the first link 1343 and the second link 1346 is achieved, so that the second link 1346 does not interfere with the lifting of the first link 1343 while driving the first link 1343 to rotate.

Wherein, this structure possesses the advantage that the dismouting degree of difficulty is low. In the assembly process, the upper end of the first link 1343 is aligned with the lower end of the through hole, and then the first link 1343 is rotated in the first direction to screw the first link 1343 into the space between the slider 1347 and the inner wall of the through hole, thereby completing the assembly. When the transmission mechanism 134 fails, the first link 1343 is rotated in a second direction opposite to the first direction, such that the first link 1343 is withdrawn from the guide 1341, thereby providing convenience for replacing and maintaining the transmission mechanism 134. Thereby realizing the technical effects of reducing the complexity of the transmission mechanism 134 and reducing the maintenance difficulty and the maintenance cost of the transmission mechanism 134.

Specifically, N guide grooves 1344 disposed in parallel are disposed in the first through hole, and the N guide grooves 1344 are distributed at intervals on the same pitch circle with the axis of the first positioning hole as an axis, so as to form an annular array of guide grooves 1344. Correspondingly, the slide block 1347 is provided with N ribs 1348 distributed in an annular shape, the ribs 1348 are disposed on an outer sidewall of the slide block 1347, and the ribs 1348 extend along an axial direction of the first positioning hole. The distribution form of the N guide grooves 1344 on the above-mentioned dividing circle is the same as that of the N ribs 1348, so as to ensure that each guide groove 1344 is inserted with one rib 1348, where N is an integer greater than 2. By providing at least three sets of guide slots 1344 and ribs 1348, the force applied to each rib 1348 can be reduced, thereby reducing the probability of bending or even breaking the rib 1348. Specifically, the N guide grooves 1344 may be uniformly distributed on the scale circle to improve the uniformity of stress, thereby further reducing the probability of damage to the ribs 1348. And further, the structure of the transmission mechanism 134 is optimized, the stability and reliability of the transmission structure are improved, and the technical effect of reducing the failure rate of the transmission mechanism 134 is achieved.

In this embodiment, the filter member 120 is provided with a groove 124, and the groove 124 extends from the body of the filter member 120 in a depth direction which coincides with the height direction of the food processing device 100. Specifically, the bottom end of the first link 1343 is inserted into the groove 124 and is connected to the bottom wall of the groove 124. The relative position of the body of the filter 120 on the first link 1343 can be raised by providing the groove 124 to provide a space under the filter 120 sufficient to accommodate solid food materials, thereby limiting the travel of the filter 120 to a predetermined interval.

Wherein the first link 1343 is detachably connected with the filter 120. By providing the first link 1343 detachably connected with the filter 120, a user can complete cleaning, maintenance or replacement of the filter 120 by removing the filter 120 from the first link 1343. The direct removal and cleaning of the filter element 120 reduces maintenance difficulties compared to solutions that require removal of the drive mechanism 134. Specifically, the bottom end of the first link 1343 is provided with an annular groove 124, an annular sealing ring is disposed in the annular groove 124, and the first link 1343 and the filter 120 are provided with a buckle and a clamping groove, so that after the filter 120 is pressed on the bottom end of the first link 1343 by the buckle and the clamping groove, the annular sealing ring between the annular groove 124 and the filter 120 can seal the filter 120 and the first link 1343, so as to avoid liquid from entering the transmission mechanism 134. And further, the structure of the transmission mechanism 134 is optimized, the layout difficulty and the failure rate of the transmission mechanism 134 are reduced, and the technical effect of providing convenience for users is achieved.

Specifically, in an alternative structural form, the first link 1343 and the filter 120 are integrally formed, and the first link 1343 and the filter 120 are manufactured through an integral molding process, so that the manufacturing process of the first link 1343 and the filter 120 can be simplified, and the manufacturing cost can be reduced. On the other hand, the structure complexity is simplified, and the structure strength is improved.
