Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and in particular to a food processor. Background Art

[0002] Existing food processors process food materials at a single speed and in a single direction. For example, a Chinese utility model patent with a publication number of CN213961527U discloses a dough and meat grinder. Although the dough and meat grinder has two speeds, they are both realized by different gear speed ratios, single direction and different buttons. The structure is that the upper and lower blades are integrated. When working, the upper and lower blades rotate at the same speed and in the same direction. When stirring food, the food rotates in the same direction. After stirring for more than ten seconds, the food will rotate upward and to the side and stick to the cup cover, the cup wall and the edge of the cup cover. When the stirred food is excessive, the food is easily spun on the blade and the edge of the cup cover and cannot be stirred. Summary of the invention

[0003] An object of an embodiment of the present invention is to provide a food processor.

[0004] The embodiment of the present invention adopts the following technical solution: a food processor, comprising:

[0007] An upper knife assembly is located in the bowl body, the upper knife assembly is arranged on the knife holder of the lower knife assembly, and the top end of the knife holder of the lower knife assembly passes through the knife holder of the upper knife assembly and extends upward; the upper knife assembly and the lower knife assembly are coaxially arranged, and the knife holders of the two are clearance-matched;

[0008] A main engine assembly is placed at the opening on the top of the bowl body, and comprises an outer shell and a driving assembly arranged in the outer shell. The driving assembly is respectively connected to the upper knife assembly and the lower knife assembly to drive the upper knife assembly and the lower knife assembly to rotate simultaneously, and the rotation direction of the upper knife assembly is opposite to the rotation direction of the lower knife assembly.

[0027] The rotation direction of the lower ring gear is changed by the upper ring gear through the lower planetary gear, so that the lower ring gear can drive the upper knife assembly connected thereto to rotate in a second direction opposite to the first direction.

[0028] In some embodiments, a first central axis hole is provided at the bottom end of the rotating shaft, and a first protrusion extending along the axial direction of the rotating shaft is provided in the first central axis hole; a first groove is provided on the outer peripheral surface of the top end of the tool holder of the lower knife assembly, and the first groove extends along the axial direction of the tool holder of the lower knife assembly, and the top end of the tool holder of the lower knife assembly extends into the first central axis hole, and the first groove cooperates with the first protrusion, so that the lower knife assembly can rotate synchronously with the rotating shaft;

DETAILED DESCRIPTION

[0051] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0052] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0053] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0054] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0055] It should also be understood that although the present application has been described with reference to some specific examples, those skilled in the art will be able to readily implement many other equivalent forms of the present application.

[0056] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0057] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0058] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0059] In order to solve the problems in the background technology, the present application provides a food processor, which can be used for cutting and / or stirring food, etc. The food can be any of the following: vegetables, meat, fungi, etc., and can also be used for dough. Of course, when processing food, two or more of vegetables, fungi and meat can be mixed for processing.

[0060] like Figure 1 and Figure 2 As shown, the food processor includes: a bowl body 1, a lower knife assembly 2, an upper knife assembly 3 and a main body assembly 4.

[0061] The top of the bowl body 1 is open, and the bowl body 1 is used to hold food. The bowl body 1 can be a bowl or cup with a circular cross section. The bowl body 1 can be made of glass, stainless steel, ceramic, etc. The material of the bowl body 1 is not specifically limited.

[0062] The bottom end of the lower knife assembly 2 is hinged in the bowl body 1. For example, a convex shaft 101 is provided on the inner bottom wall of the bowl body 1, and the convex shaft 101 extends upward from the inner bottom wall of the bowl body 1. The bottom end of the lower knife assembly 2 is connected to the convex shaft 101, and the lower knife assembly 2 can rotate around the convex shaft 101. The convex shaft 101 can be made of stainless steel or other materials. The lower knife assembly 2 includes a lower knife holder 201 and a lower processing part 202 for processing the food in the lower half of the bowl body 1; the lower processing part 202 is arranged on the lower knife holder 201, and can adopt the structure of a stirring rod or a cutting knife, and is used for stirring and / or cutting the food. The function of the lower processing part 202 is specifically set and selected according to the needs of the food processor.

[0063] The upper knife assembly 3 is located in the bowl body 1. The upper knife assembly 3 is arranged on the lower knife holder 201 of the lower knife assembly 2. The lower knife holder 201 is in the shape of a long axis. The upper knife assembly 3 includes an upper knife holder 301 and an upper processing portion 302. Similar to the lower knife assembly 2, the upper processing portion 302 is arranged on the upper knife holder 301 for processing the food in the upper half of the bowl body 1. The upper knife holder 301 is in the shape of a circular tube. The top end of the lower knife holder 201 can pass through the upper knife holder 301 and extend upward to the top of the upper knife holder 301. The upper knife assembly 3 is coaxially arranged with the lower knife assembly 2, and the knife holders of the two are clearance-matched.

[0064] For example, the lower knife holder 201 and the upper knife holder 301 are loosely matched, and while the lower knife holder 201 rotates, the upper knife holder 301 can rotate around the lower knife holder 201, so that the lower processing part 202 on the lower knife holder 201 and the upper processing part 302 on the upper knife holder 301 can rotate synchronously with the lower knife holder 201 and the upper knife holder 301 respectively, thereby realizing the processing of the lower half and the upper half of the food in the bowl body 1.

[0065] When stirring the food, the upper processing part 302 and the lower processing part 202 may be stirring rods; when cutting the food, the upper processing part 302 and the lower processing part 202 may be cutting knives.

[0066] The host component 4 is placed at the open part of the top of the bowl body 1, and includes a shell 400 and a driving component arranged in the shell 400. The driving component is connected to the upper knife component 3 and the lower knife component 2 respectively to drive the upper knife component 3 and the lower knife component 2 to rotate simultaneously, and the rotation direction of the upper knife component 3 is opposite to the rotation direction of the lower knife component 2. The lower half of the host component 4 can be deeply connected to the upper knife component 3 and the lower knife component 2 located in the bowl body 1. The host component 4 is connected to the upper knife component 3 and the lower knife component 2 respectively, and the upper knife component 3 and the lower knife component 2 are driven to rotate in different directions at the same time, which solves the problem that when the food in the bowl body 1 is processed in the same direction, the food is piled up upward, and some food is located at the top edge of the bowl body 1 and cannot be processed. Evenly processed food can be obtained, and the processing effect of food is improved. Even if the amount of food in the bowl body 1 is large, it can also achieve good stirring or cutting of food, which improves the processing efficiency of food.

[0067] In some embodiments, the driving assembly includes a motor 401 and a gear box 402. The gear box 402 includes a shell and an upper gear assembly and a lower gear assembly disposed in the shell. The upper gear assembly is located above the lower gear assembly. The upper gear assembly is connected to the lower gear assembly. When the upper gear assembly rotates, the upper gear assembly can drive the lower gear assembly to rotate synchronously therewith.

[0068] The output shaft of the motor 401 is connected to the upper gear assembly and drives the upper gear assembly to rotate.

[0069] In addition to being connected to the lower gear assembly and driving the lower gear assembly to rotate, the upper gear assembly is also connected to the lower knife assembly 2 and drives the lower knife assembly 2 to rotate along the first direction, such as Figure 3 As shown, the first direction may be counterclockwise.

[0070] The lower gear assembly is connected to the upper knife assembly 3 to drive the upper knife assembly 3 to rotate along the second direction.

[0071] in,

[0072] The second direction is opposite to the first direction. That is, the second direction may be a clockwise direction. Of course, the first direction here may also be a clockwise direction, as long as the first direction is opposite to the second direction.

[0073] The upper gear assembly and the lower gear assembly of the gear box 402 respectively drive the lower knife assembly 2 and the upper knife assembly 3 to rotate simultaneously in different directions, so as to process the food in multiple directions, thereby achieving the processing of food without dead angles, making the food processing more uniform and having better effect. The upper knife assembly 3 and the lower knife assembly 2 are driven in the form of a gear assembly, and the rotation stability of the upper knife assembly 3 and the lower knife assembly 2 can also be improved.

[0074] In some embodiments, the driving assembly drives the upper knife assembly 3 and the lower knife assembly 2 to rotate simultaneously at the same or different speeds. By reasonably setting the transmission ratio between the upper gear assembly and the lower gear assembly, the upper knife assembly 3 and the lower knife assembly 2 can be rotated at the same speed. Of course, the upper knife assembly 3 and the lower knife assembly 2 can also be rotated at different speeds.

[0075] For example, the rotation speed of the lower knife assembly 2 can be controlled to be greater than the rotation speed of the upper knife assembly 3. Since most of the food in the bowl body 1 is located in the lower half of the bowl body 1, the food in the lower half of the bowl body 1 can be processed more quickly by the lower knife assembly 2 with a higher rotation speed, thereby preventing the unprocessed food from piling up. Of course, the specific rotation speeds of the upper knife assembly 3 and the lower knife assembly 2 can be selected and set as needed, which is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0076] Because the upper blade assembly 3 and the lower blade assembly 2 are driven by different gear assemblies, the rotation speeds of the upper blade assembly 3 and the lower blade assembly 2 can be the same or different. The upper blade assembly 3 and the lower blade assembly 2 rotating at different rotation speeds can further avoid food accumulation and improve food processing effects.

[0077] In some embodiments, Figure 3 and Figure 4 As shown, the upper gear assembly includes a sun gear 403 , a plurality of upper planetary gears 404 , a rotating shaft 405 and an upper ring gear 406 .

[0078] There is one sun gear 403, which is connected to the output shaft of the motor 401 and rotates in the second direction under the drive of the motor 401. Of course, it can be understood that when the motor 401 is a forward and reverse motor 401 and the motor 401 is reversed, the sun gear 403 can also rotate in the first direction under the drive of the motor 401.

[0079] The plurality of upper planetary gears 404 are located on the outer side of the sun gear 403, and the plurality of upper planetary gears are all meshed with the outer side of the sun gear 403, and rotate in the first direction driven by the sun gear 403. The plurality of upper planetary gears can be evenly arranged on the outer periphery of the sun gear 403, so that the sun gear 403 can smoothly drive the plurality of upper planetary gears to rotate. Continuing with the above embodiment, when the motor 401 is reversed, the plurality of upper planetary gears 404 can also rotate in the second direction.

[0080] The rotating shaft 405 is coaxially arranged with the lower tool holder 201. A disc-shaped structure 4051 is arranged on the top of the rotating shaft 405. A plurality of upper planetary gear shafts are arranged on the disc-shaped structure 4051. A plurality of upper planetary gears 404 are mounted on the plurality of upper planetary gear shafts. The plurality of upper planetary gears rotate to drive the rotating shaft 405 to rotate along a first direction. The bottom end of the rotating shaft 405 is connected to the top end of the lower tool holder 201 to drive the lower tool assembly 2 to rotate coaxially with the rotating shaft 405 along the first direction.

[0081] The lower knife assembly 2 rotates in the first direction while stirring or cutting the food in the bowl body 1 in the first direction. While being stirred or cut, the food in the lower half of the bowl body 1 moves upward along the inner wall of the bowl body 1 in the first direction. The upper knife assembly 3 rotates in the second direction, and the food in the upper half of the bowl body 1 is stirred or cut by the upper knife assembly 3 in the second direction. At the same time, the food moving upward from the lower half of the bowl body 1 is affected by the rotation of the upper knife assembly 3 when it is close to the upper knife assembly 3. Under the action of the upper knife assembly 3, the food in the lower half of the bowl body 1 does not continue to move upward when it moves upward to the position of the upper knife assembly 3, or the amount of food moving upward is very small. Therefore, the problem that the food accumulates upward during the stirring or cutting process, resulting in that some food cannot be stirred or cut well is solved; at the same time, the problem that the food adheres to the inner wall of the bowl body 1 is also solved. When stirring the food, the food is fully stirred, and even if the amount of food in the bowl body 1 is large, the food can be stirred or cut well, thereby improving the processing efficiency of the food.

[0082] The gear teeth of the upper ring gear 406 are not arranged on its outer circumference, but are arranged on the lower surface of the upper ring gear 406, that is, the lower surface of the upper ring gear 406 is provided with lower gear teeth 4061 that circle the upper ring gear 406. The central axis of the upper ring gear 406 is fixed together with the rotating shaft 405, and the two are coaxially arranged. For example, the upper ring gear 406 can be locked on the rotating shaft 405 so that the upper ring gear 406 and the rotating shaft 405 rotate synchronously in the first direction. The upper ring gear 406 is connected to the lower gear assembly to drive the lower gear assembly to move.

[0083] Through the cooperation of multiple gears in the upper gear assembly and the rotating shaft 405, the lower knife assembly 2 is driven to rotate stably along the first direction, and at the same time, the lower gear assembly can be driven to move, and then the upper knife assembly 3 is driven to rotate along the second direction through the lower gear assembly.

[0084] In some embodiments, the Figure 3 and Figure 4 The lower gear assembly includes a plurality of lower planetary gears 407 and a lower ring gear 408 .

[0085] The multiple lower planetary gears 407 are vertically matched with the upper ring gear 406, and the gear teeth of the multiple lower planetary gears 407 are meshed with the lower gear teeth 4061, so that the multiple lower planetary gears 407 can rotate under the drive of the upper ring gear 406. The multiple lower planetary gears 407 can be evenly arranged below the upper ring gear 406, so that the upper ring gear 406 can smoothly drive the multiple lower planetary gears 407 to rotate.

[0086] The gear teeth of the lower ring gear 408 are similar to those of the upper ring gear 406, that is, the gear teeth of the lower ring gear 408 are not arranged on the outer circumferential surface of the lower ring gear 408, but are arranged on the upper surface of the lower ring gear 408. That is, the upper surface of the lower ring gear 408 is provided with upper gear teeth 4081 that circle the lower ring gear 408, and the upper gear teeth 4081 are meshed with the gear teeth of the plurality of lower planetary gears 407, so that the lower ring gear 408 can rotate in the second direction under the drive of the plurality of lower planetary gears 407. The lower ring gear 408 is coaxially arranged with the upper ring gear 406, and the central axis of the lower ring gear 408 is connected with the upper knife assembly 3, and the upper knife assembly 3 is coaxially arranged with the lower ring gear 408 to drive the upper knife assembly 3 to rotate coaxially with the lower ring gear 408 in the second direction.

[0087] The upper ring gear 406 is vertically matched with multiple lower planetary gears 407, so that the upper ring gear 406 can change the rotation direction of the lower ring gear 408 through multiple lower planetary gears 407, thereby allowing the upper knife assembly 3 connected to the lower ring gear 408 to rotate in the opposite direction to the lower knife assembly 2.

[0088] The upper ring gear 406 changes the rotation direction of the lower ring gear 408 through the lower planetary gear, so that the lower ring gear 408 can drive the upper knife assembly 3 connected thereto to rotate in a second direction opposite to the first direction. Of course, when the lower knife assembly 2 rotates in the second direction, the upper knife assembly 3 can rotate in the first direction, and the rotation directions of the two are opposite.

[0089] In some embodiments, a first central axis hole is provided at the bottom end of the rotating shaft 405, and a first protrusion (not shown in the figure) extending along the axial direction of the rotating shaft 405 is provided in the first central axis hole. The first protrusion may be in the shape of a long strip, and its length direction is the axial direction of the lower tool holder 201. The first protrusion may be one or more than two. Figure 2 As shown, the top peripheral surface of the tool holder of the lower knife assembly 2 is provided with a first groove 2011, and the first groove 2011 extends along the axial direction of the tool holder of the lower knife assembly 2, that is, the first groove 2011 can be a long groove, and its shape is adapted to the first protrusion. The top of the tool holder of the lower knife assembly 2 extends into the first central axis hole, and the first groove 2011 cooperates with the first protrusion so that the rotation shaft 405 can transmit power to the lower knife assembly 2 when the rotation shaft 405 rotates, so that the lower knife assembly 2 can rotate synchronously and coaxially with the rotation shaft 405 in the first direction.

[0090] A second central axis hole is provided at the bottom end of the central axis of the lower ring gear 408. A second protrusion (not shown in the figure) extending axially along the central axis of the lower ring gear 408 is provided in the second central axis hole. The second protrusion may also be a long strip-shaped protrusion. Figure 2 The outer peripheral surface of the upper portion of the tool holder of the upper knife assembly 3 is provided with a second groove 3011, and the second groove 3011 extends along the axial direction of the tool holder of the upper knife assembly 3. The second groove 3011 can be a long groove adapted to the second protrusion. The lower ring gear 408 is coaxially arranged with the upper knife assembly 3, and the upper portion of the tool holder of the upper knife assembly 3 extends into the second central axis. The second groove 3011 cooperates with the second protrusion so that the lower ring gear 408 can transmit power to the upper knife assembly 3 when rotating, so that the upper tool holder 301 assembly and the lower ring gear 408 rotate synchronously and coaxially in the second direction.

[0091] The first groove 2011 at the top of the tool holder of the lower knife assembly 2 cooperates with the first protrusion of the first central axis hole on the rotating shaft 405, so that the rotating shaft 405 can synchronously drive the lower knife assembly 2 to rotate along the first direction; the second groove 3011 on the upper part of the tool holder of the upper knife assembly 3 cooperates with the second protrusion of the second central axis hole provided at the bottom end of the central axis of the lower ring gear 408, so that the central axis of the lower ring gear 408 can drive the upper knife assembly 3 to rotate synchronously with the lower knife assembly 2 along the second direction.

[0092] In some embodiments, the Figure 3 , Figure 4 and Figure 5 The housing includes a gear box upper cover 4021, a gear box bracket 4022 and a gear box lower cover 4023.

[0093] The gearbox upper cover 4021 is located above the gearbox bracket 4022, connected with the gearbox bracket 4022 and enclosed to form a first accommodation space, and the upper structure of the sun gear 403, multiple upper planetary gears and the rotating shaft 405 is accommodated in the first accommodation space. The upper structure of the rotating shaft 405 may include a disc-shaped structure 4051 at the top of the rotating shaft 405 and multiple upper planetary gear shafts arranged on the disc-shaped structure 4051. The first accommodation space can form a protection for the sun gear 403, multiple upper planetary gears and the upper structure of the rotating shaft 405.

[0094] The gear box bracket 4022 is located below the gear box bracket 4022, connected to the gear box bracket 4022 and enclosed to form a second accommodation space, and the upper ring gear 406, the lower structure of the rotating shaft 405, the multiple lower planetary gears and the lower ring gear 408 are accommodated in the second accommodation space. The second accommodation space can form a protection for the lower structure, the multiple lower planetary gears and the lower ring gear 408.

[0095] The gear box upper cover 4021, the gear box bracket 4022 and the gear box lower cover 4023 can be detachably connected together by bolts, so as to facilitate the disassembly and assembly and maintenance of the structural parts in the first accommodating space and the second accommodating space.

[0096] The gear box bracket 4022 cooperates with the gear box upper cover 4021 and the gear box lower cover 4023 respectively to form two upper and lower accommodating spaces, so as to set the upper knife assembly 3 and the lower knife assembly 2 in the housing of the gear box.

[0097] In some embodiments, in combination Figure 1 and Figure 2 The host component 4 also includes a button 409 and a return spring 410, wherein the button 409 is arranged at the top of the housing 400. Of course, the button 409 can also be arranged at other positions as needed, as long as the motor 401 can be started / turned off when the button 409 is pressed. Taking the button 409 arranged at the top of the housing 400 as an example, the top of the button 409 is exposed on the top surface of the housing 400, and the bottom of the button 409 goes deep into the housing 400. The top of the return spring 410 abuts against the bottom of the button 409, and the bottom of the return spring 410 abuts against the inner wall of the housing 400. For example, a platform extending into the housing 400 is arranged on the inner wall of the housing 400, and the bottom of the return spring 410 abuts against the platform. Alternatively, the bottom end of the return spring 410 is fixed to the inner wall of the housing 400.

[0098] When the button 409 is pressed, the button 409 applies a force to the return spring 410, and the button 409 compresses the return spring 410 downward until the button 409 contacts the switch of the motor 401 and applies a force to the switch of the motor 401, thereby starting the switch of the motor 401 and starting / stopping the motor 401. When the button 409 is released, the button 409 releases the compression effect on the return spring 410, and the return spring 410 stretches and resets, and drives the button 409 to reset.

[0099] The button 409 can be pressed as needed, and the button 409 can be reset by the reset spring 410 to start / stop the motor 401 to process the food or stop processing the food.

[0100] Of course, other methods may be used to start / stop the motor 401 as needed, and this is only used as an example.

[0101] In some embodiments, the upper blade assembly 3 includes an upper blade holder 301 and an upper blade, and the upper blade is arranged on the outer peripheral surface of the upper blade holder 301. Here, the upper blade can be a cutting knife, and a blade can be arranged on one side of the cutting knife, or on both sides thereof. It can also be a stirring rod, which is specifically arranged according to the needs of the food processor. The food processor can be equipped with multiple sets of upper blade assemblies 3 and lower blade assemblies 2 with different structural forms of upper blades and lower blades, which can be replaced as needed.

[0102] Taking the above blade as a cutting knife as an example, the cutting knife can be one or more than two. The upper blade extends from the upper blade holder 301 toward the inner wall of the bowl body 1. The upper blade can extend to a position 2mm to 5mm away from the inner wall of the bowl body 1 to fully cut the food in the bowl body 1 and avoid the gap between the upper blade and the inner wall of the bowl body 1 being too large, resulting in the food located in the gap position not being cut.

[0103] Of course, it is understandable that the above gap distance can also be set as needed. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0104] The lower blade assembly 2 includes a lower blade holder 201 and a lower blade, and the lower blade is arranged on the outer peripheral surface of the lower blade holder 201. Similar to the upper blade assembly 3, the number of the lower blades can also be one, or more than two, and the number of the lower blades can be the same as the number of the upper blades, or different. The structural form of the lower blade is similar to that of the upper blade, and will not be repeated here.

[0105] When the upper knife assembly 3 and the lower knife assembly 2 rotate in opposite directions, the upper blade and the lower blade respectively process the food in the bowl body 1 in different directions, thereby preventing the food in the bowl body 1 from moving in one direction in the bowl body 1 and causing accumulation, thereby improving the uniformity of the blade's processing of the food and ensuring the processing effect of the food.

[0106] In some embodiments, the food processor further comprises a bowl cover 411, which is buckled on the opening at the top of the bowl body 1. A through hole is provided in the center of the bowl cover 411, and the lower part of the main unit assembly 4 passes through the through hole to be connected to the upper knife assembly 3 and the lower knife assembly 2 in the bowl body 1 respectively. The bowl cover 411 blocks the opening at the top of the bowl body 1 to prevent the food in the bowl body 1 from leaking from the edge of the bowl body 1 when the food moves upward. The bowl cover 411 can be made of transparent plastic material, and the plastic can be food-grade plastic. The bowl cover 411 can be tightly buckled on the edge of the opening at the top of the bowl body 1 to prevent the food in the bowl body 1, especially the juice of the food, from leaking from the edge of the opening at the top of the bowl body 1.

[0107] A number of embodiments of the present invention have been described in detail above, but the present invention is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications to the embodiments based on the concept of the present invention, and these variations and modifications should all fall within the scope of protection claimed by the present invention.
