Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with stable rotation. Background Technology

[0002] Existing food processors typically consist of a main unit and a detachable cup assembly located on top of the main unit. The main unit houses a motor, and the cup assembly contains a stirring element connected to the motor. When using the food processor, the user places ingredients into the cup, and the motor drives the stirring element to rotate at high speed, processing the ingredients. Current methods of connecting the motor and stirring element involve attaching a connector to the motor shaft and another connector to the bottom of the stirring element's blade shaft. After the cup assembly is in place, these connectors engage to transmit torque. However, this method requires a through-hole in the bottom wall of the cup for the upper connector to pass through, and a bearing and seal must be installed within this hole to ensure smooth rotation and a tight seal. This results in a complex structure and creates hard-to-clean areas at the bottom of the cup, making thorough cleaning difficult.

[0003] To address the aforementioned issues, Chinese patent CN202211320481.5 discloses a food processor that incorporates a driven magnet (a permanent magnet) at the bottom of the mixing element. An electromagnetic drive device is also included within the main unit. This device generates a changing magnetic field when energized. After the cup is installed, the driven magnet attracts the electromagnetic drive device under the influence of the magnetic field, causing it to rotate within the cup. This eliminates the need for drilling holes in the bottom wall of the cup, removing cleaning dead zones and allowing for thorough cleaning. However, this drive method requires a long connecting shaft for the blades to connect to the driven magnet. Without radial restraint, the blades and the entire rotating assembly are susceptible to vibration and wobbling due to disturbances from the food during rotation. This can lead to unstable blade rotation or even jamming. Furthermore, the driven magnet rotates within the food, and the disturbances from the food significantly reduce its dynamic balance, further exacerbating the wobbling of the entire rotating assembly and severely impacting the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a food processing machine with stable rotation, in order to solve the problem of large sway during rotation caused by the need for a long connecting shaft between the blade and the driven magnet and the lack of a radial limiting structure, under the premise that the existing food processing machine uses an electromagnetic drive device and a driven magnet to realize the rotation of the crushing device in order to reduce the dead corner of cleaning.

[0005] To achieve the above objectives, this utility model provides a food processing machine with stable rotation, including a main unit and a detachable cup body located above the main unit and containing a pulverizing device. The pulverizing device includes blades, a blade holder located below the blades, and a magnetic reluctance rotor located within the blade holder. The blades and the magnetic reluctance rotor are connected by a connecting shaft, and the magnetic reluctance rotor has a body connected to the connecting shaft and multiple convex poles extending radially outward from the body. The food processing machine also includes a driving device, which can generate a changing magnetic field and drive the magnetic reluctance rotor to rotate, thereby driving the blades to rotate.

[0006] This application simplifies the food processing machine by comprising a pulverizing device consisting of blades, a blade holder below the blades, and a reluctance rotor within the blade holder. The blades and the reluctance rotor are connected by a connecting shaft. The food processor also includes a drive device that generates a changing magnetic field to drive the reluctance rotor, which in turn rotates the blades. When the user places the cup on the main unit, the drive device activates and generates a changing magnetic field. The reluctance rotor, influenced by the magnetic field, begins to rotate, driving the blades to process the food. Compared to existing methods that require upper and lower connectors for torque transmission, this eliminates the need for openings at the bottom of the cup, thus eliminating the need for seals and bearings, simplifying the cup structure and reducing cleaning dead zones, making cleaning easier. Furthermore, compared to existing methods that use two magnetically attached disks to drive the blades, this eliminates the need for a motor and active disk on the main unit, resulting in a more compact structure, reducing the overall size, especially the axial dimension, and lowering the weight of the machine, making it easier for users to handle. Moreover, the reluctance rotor has no magnetic attraction, effectively preventing the passive disk from attracting metal parts when the cup is placed on a table, as is common in existing technologies, thus improving the user experience.

[0007] Meanwhile, the reluctance rotor is equipped with a main body and multiple salient poles extending radially outward from the main body. When the driving device generates a changing magnetic field, the multiple salient poles can interact with the magnetic field to form a stable rotational torque. At the same time, while the main body is connected to the connecting shaft, the closed structure design of the main body greatly increases the weight of the main body, so that the center of gravity of the entire reluctance rotor is concentrated at its center of gravity, making it more stable during rotation and maintaining the dynamic balance of the reluctance rotor. This ensures that the blades connected to it remain stable even when rotating at high speed, effectively avoiding the situation where the blades vibrate or wobble during high-speed rotation due to the excessive length of the connecting shaft, which would lead to poor pulverization effect or even failure to rotate. At the same time, the reluctance rotor is located inside the blade holder, avoiding contact with the food, reducing the difficulty of cleaning and preventing the reluctance rotor from contaminating the food. It also effectively avoids the reluctance rotor from disturbing the food, which would cause unstable rotation. This helps to further improve the rotational stability of the entire pulverizing device, achieve stable dynamic balance, ensure that the food is processed evenly and finely, and improve processing efficiency.

[0008] In a preferred embodiment of a rotationally stable food processing machine, a baffle connecting the body and the salient pole is provided on the bottom wall of the salient pole near the drive device or on the top wall of the salient pole away from the drive device.

[0009] By providing a baffle connecting the main body and the salient pole on the bottom wall near the drive device or on the top wall away from the drive device, the uniformity of the overall weight of the reluctance rotor can be further improved by extending the baffle outward from the main body. This allows the reluctance rotor to maintain a more stable operating state when rotating at high speed, further improving its dynamic balance effect and reducing vibration and sway caused by uneven weight distribution.

[0010] In a preferred embodiment of a rotationally stable food processing machine, a baffle extends to connect with the end of a salient pole extension.

[0011] By setting the baffle to extend to connect with the extended end of the salient pole, the entire baffle and the salient pole form an integrated structure, which can further improve the uniformity of the overall weight of the magnetic reluctance rotor, further improve its dynamic balance effect, ensure the stability of the rotation of the entire crushing device, and improve the effect of food processing.

[0012] In a preferred embodiment of a rotationally stable food processing machine, the reluctance rotor is further provided with annular ribs connecting the salient poles.

[0013] By adding annular ribs to connect the salient poles to the reluctance rotor, the annular ribs not only enhance the structural stability between the salient poles, but also further even out the weight distribution of the reluctance rotor. This allows the reluctance rotor to maintain dynamic balance more stably when rotating at high speed, effectively reducing vibration and sway, and ensuring that the blade remains dynamically stable when cutting food.

[0014] In a preferred embodiment of a rotationally stable food processing machine, the annular ribs are connected at the middle position of each salient pole; or,

[0015] The ring-shaped ribs are connected to the extended ends of each salient pole.

[0016] In a preferred embodiment of a rotationally stable food processing machine, the cutter holder includes a housing with a receiving cavity, a reluctance rotor disposed within the receiving cavity, a connecting shaft extending into the receiving cavity to connect with the main body, and a bearing provided between the connecting shaft and the housing.

[0017] By installing a bearing between the connecting shaft and the housing, the bearing provides radial support to the connecting shaft and provides support force in the middle of the connecting shaft, ensuring the radial stability of the connecting shaft. This avoids the situation where the connection length between the reluctance rotor and the blade is too long, which would cause a large sway even if the two are slightly wobbled. This further improves the synchronous stability of the blade and the reluctance rotor and ensures the stability of the blade rotation.

[0018] In a preferred embodiment of a rotationally stable food processing machine, the main unit is equipped with a control board, and the drive device is a stator assembly electrically connected to the control board.

[0019] By incorporating a control board within the main unit and a stator assembly electrically connected to the control board as the drive unit, the control board can precisely regulate the current and frequency of the stator assembly when the user is using the food processor. This allows the machine to automatically adjust the speed and torque of the reluctance rotor according to the hardness of the ingredients and the cutting requirements, ensuring precise and efficient processing of ingredients each time and improving the overall processing effect.

[0020] In a preferred embodiment of a rotationally stable food processing machine, the bottom end of the connecting shaft is provided with a radially reduced fixed shaft, and the body is provided with a fixing hole for fixed connection with the fixed shaft.

[0021] By providing a radially reduced fixed shaft at the bottom of the connecting shaft and a fixing hole for fixed connection with the fixed shaft in the main body, the connecting shaft is connected to the main body through the fixed connection with the fixing hole, ensuring the stability of the connection between the two. At the same time, the fixed shaft is radially reduced relative to the connecting shaft, so that after the fixed shaft is connected to the fixing hole, the bottom end of the connecting shaft abuts against the top wall of the main body, realizing axial positioning of the two and avoiding possible axial displacement of the reluctance rotor during rotation, further improving the position and rotation stability of the reluctance rotor.

[0022] In a preferred embodiment of a rotationally stable food processing machine, a fixed shaft extends out of the bottom end of a fixed hole, and the crushing device further includes a fastener fastened to the bottom end of the fixed shaft, the top end of the fastener abutting against the bottom wall of the body.

[0023] By including a fastener at the bottom of the fixed shaft in the crushing device, the fixed shaft is double-fixed with the fixed hole and the fastener, which further improves the stability of the connection between the connecting shaft and the reluctance rotor. At the same time, the top of the fastener abuts against the bottom wall of the body, realizing the axial clamping and positioning of the body, effectively preventing the axial movement of the reluctance rotor during high-speed operation, ensuring the smoothness and precision of the entire processing process, and further improving the stability of the blade rotation.

[0024] In a preferred embodiment of a rotationally stable food processing machine, the central portion of the bottom of the body is recessed to form a mounting groove, and fasteners are located within the mounting groove.

[0025] By recessing the middle part of the bottom of the body to form a mounting groove, the fastener is located in the mounting groove, which effectively avoids the fastener protruding from the bottom of the body, causing interference between the fastener and the bottom wall of the blade holder and generating friction noise. This helps to further improve the stability of the crushing device's rotation. Attached Figure Description

Detailed Implementation

[0037] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0038] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0039] like Figures 1 to 8 As shown, this utility model provides a food processing machine with stable rotation, including a main unit and a detachable cup body 1 located above the main unit and containing a crushing device 2. The crushing device 2 includes a blade 21, a blade holder 22 located below the blade 21, and a magnetic reluctance rotor 23 located within the blade holder 22. The blade 21 and the magnetic reluctance rotor 23 are connected by a connecting shaft 24. The magnetic reluctance rotor 23 has a body 231 connected to the connecting shaft 24 and multiple convex poles 232 extending radially outward from the body 231. The food processing machine also includes a driving device 3, which can generate a changing magnetic field and drive the magnetic reluctance rotor 23 to rotate, thereby driving the blade 21 to rotate. It should be noted that this application does not specifically limit the location of the driving device 3. As shown in Figure 1, it can be located in the cup base below the cup body 1 or in the main unit, which will not be elaborated further here.

[0040] This application simplifies the food processing machine by configuring the pulverizing device 2 as a blade 21, a blade holder 22 located below the blade 21, and a reluctance rotor 23 located within the blade holder 22. The blade 21 and the reluctance rotor 23 are connected by a connecting shaft 24. The food processor also includes a drive device 3 that generates a changing magnetic field and drives the reluctance rotor 23 to rotate, thereby rotating the blade 21. When the user places the cup 1 on the main unit, the drive device 3 operates and generates a changing magnetic field. The reluctance rotor 23, influenced by the magnetic field, begins to rotate, driving the blade 21 to process the food. Compared to existing methods that require upper and lower connectors for torque transmission, this eliminates the need for openings at the bottom of the cup 1, thus eliminating the need for seals and bearings 26, simplifying the cup 1 structure and reducing cleaning dead zones, making it easier for the user to clean the cup 1. Furthermore, compared to existing methods that use two magnetically attached disks to drive the blade 21, this eliminates the need for a motor and active disk on the main unit, making the main unit more compact and reducing its size, especially the axial dimension, while also lowering the overall weight and making it easier for the user to handle. Moreover, the magnetic reluctance rotor 23 has no magnetic attraction, which can effectively avoid the situation in the prior art where the driven disk attracts metal parts when the cup body 1 is placed on the table, thus improving the user experience.

[0041] Meanwhile, the reluctance rotor 23 is provided with a body 231 and multiple salient poles 232 extending radially outward from the body 231. When the driving device 3 generates a changing magnetic field, the multiple salient poles 232 can interact with the magnetic field to form a stable rotational torque. At the same time, while the body 231 is connected to the connecting shaft 24, the closed structure design of the body 231 greatly increases the weight of the body 231, so that the center of gravity of the entire reluctance rotor 23 is concentrated at its center of gravity position, making it more stable during rotation and maintaining the dynamic balance of the reluctance rotor 23. This ensures that the blade 21 connected to it also rotates at high speed. It can maintain stability and effectively avoid the situation where the blade 21 vibrates or wobbles during high-speed rotation due to the excessive length of the connecting shaft 24, which would cause the blade 21 to have poor crushing effect or even fail to rotate. At the same time, the magnetic reluctance rotor 23 is located inside the blade holder 22, avoiding contact with the food, reducing the difficulty of cleaning and preventing the magnetic reluctance rotor 23 from contaminating the food. It can also effectively prevent the magnetic reluctance rotor 23 from being disturbed by the food, which would cause its rotation to be unstable. This helps to further improve the rotational stability of the entire crushing device 2, achieve stable dynamic balance, ensure that the food is processed evenly and finely, and improve processing efficiency.

[0042] It should be noted that this application does not specifically limit the proportion of the body 231 and the salient pole 232 on the reluctance rotor 23. As a preferred embodiment of this application, such as Figure 6 As shown, the radius R1 of the body 231 and the radius R2 of the salient pole 232 extending outward from the body 231 satisfy: R1≥R2, more preferably, R1=R2, or R1=2R2.

[0043] It should also be noted that this application does not specifically limit the structure of the salient pole 232, which can be any of the following embodiments:

[0044] Example 1: As Figure 2 , Figure 4 , Figure 5 As shown, in this embodiment, the bottom wall of the salient pole 232 near the drive device 3 or the top wall away from the drive device 3 is provided with a baffle 233 connecting the body 231 and the salient pole 232. More preferably, the baffle 233 is provided on the top wall away from the drive device 3.

[0045] By providing a baffle 233 connecting the main body 231 and the salient pole 232 on the bottom wall near the drive device 3 or on the top wall away from the drive device 3, the baffle 233 extends outward from the main body 231, which can further improve the uniformity of the overall weight of the reluctance rotor 23, thereby maintaining a more stable operating state when the reluctance rotor 23 rotates at high speed, further improving its dynamic balance effect, and reducing vibration and sway caused by uneven weight distribution.

[0046] It should be further noted that this application does not specifically limit the relative positional relationship between the baffle 233 and the salient pole 232 in this embodiment. As a preferred embodiment, such as Figure 4 As shown, the baffle 233 extends to connect with the extended end of the salient pole 232.

[0047] By configuring the baffle 233 to extend and connect with the extended end of the salient pole 232, the entire baffle 233 and the salient pole 232 form an integrated structure, which can further improve the uniformity of the overall weight of the reluctance rotor 23, further improve its dynamic balance effect, ensure the stability of the rotation of the entire crushing device 2, and improve the processing effect of food. Of course, the baffle 233 is not limited to the above configuration; it can also extend to protrude from the outside of the salient pole 232, or its outer diameter can be smaller than that of the salient pole 232, which will not be elaborated here.

[0048] Example 2: As Figure 7 , Figure 8 As shown, in this embodiment, the reluctance rotor 23 is further provided with annular ribs 234 that connect each salient pole 232.

[0049] By providing annular ribs 234 that connect each salient pole 232 to the magnetic reluctance rotor 23, the annular ribs 234 not only enhance the structural stability between each salient pole 232, but also further even out the weight distribution of the magnetic reluctance rotor 23, so that the magnetic reluctance rotor 23 can maintain dynamic balance more stably when rotating at high speed, effectively reducing vibration and sway, and ensuring that the blade 21 always maintains dynamic stability when cutting food.

[0050] It should be further noted that, in this embodiment, the location of the annular rib 234 is not specifically limited, and it can be any of the following embodiments:

[0051] Implementation method 1: such as Figure 8 As shown, in this embodiment, the annular rib 234 is connected to the middle position of each salient pole 232.

[0052] Implementation method 2: such as Figure 7 As shown, in this embodiment, the annular rib 234 is connected to the extended end of each salient pole 232.

[0053] As a preferred embodiment of this application, such as Figure 3 As shown, the tool holder 22 includes a housing 221 with a receiving cavity 2211, a magnetic reluctance rotor 23 is disposed in the receiving cavity 2211, a connecting shaft 24 extends into the receiving cavity 2211 to connect with the body 231, and a bearing 26 is provided between the connecting shaft 24 and the housing 221.

[0054] By providing a bearing 26 between the connecting shaft 24 and the housing 221, the bearing 26 provides radial support to the connecting shaft 24 and provides support force in the middle of the connecting shaft 24, ensuring the radial stability of the connecting shaft 24. This avoids the situation where the connection length between the reluctance rotor 23 and the blade 21 is too long, causing a large sway even with slight oscillations. This further improves the synchronous stability of the blade 21 and the reluctance rotor 23, ensuring the stability of the blade 21's rotation.

[0055] In a preferred embodiment of this application, the host is provided with a control board, and the drive device 3 is a stator assembly electrically connected to the control board.

[0056] By incorporating a control board within the main unit and a stator assembly electrically connected to the drive unit 3, the control board within the main unit can precisely regulate the current and frequency of the stator assembly when the user is using the food processor. This allows the control board to automatically adjust the speed and torque of the reluctance rotor 23 according to the hardness of the ingredients and the cutting requirements, ensuring precise and efficient processing of ingredients each time and improving the overall processing effect.

[0057] It should be noted that this application does not specifically limit how the connecting shaft 24 is connected to the body 231. As one preferred embodiment of this application, such as... Figure 3 As shown, the bottom end of the connecting shaft 24 is provided with a radially reduced fixed shaft 241, and the body 231 is provided with a fixing hole for fixed connection with the fixed shaft 241.

[0058] By providing a radially reduced fixed shaft 241 at the bottom of the connecting shaft 24, and a fixing hole for fixed connection with the fixed shaft 241 in the body 231, the connecting shaft 24 is connected to the body 231 through the fixed connection with the fixing hole, ensuring the stability of the connection between the two. At the same time, the fixed shaft 241 is radially reduced relative to the connecting shaft 24, so that after the fixed shaft 241 is connected to the fixing hole, the bottom end of the connecting shaft 24 abuts against the top wall of the body 231, realizing axial positioning of the two, avoiding possible axial displacement of the reluctance rotor 23 during rotation, and further improving the position and rotation stability of the reluctance rotor 23.

[0059] Furthermore, such as Figure 3 As shown, the fixed shaft 241 extends out of the bottom of the fixed hole, and the crushing device 2 also includes a fastener 25 fastened to the bottom of the fixed shaft 241, with the top of the fastener 25 abutting against the bottom wall of the body 231.

[0060] By including a fastener 25 at the bottom of the fixed shaft 241 in the crushing device 2, the fixed shaft 241 is double-fixed with the fixed hole and the fastener 25, which further improves the stability of the connection between the connecting shaft 24 and the reluctance rotor 23. At the same time, the top of the fastener 25 abuts against the bottom wall of the body 231, realizing the axial up and down clamping and positioning of the body 231, effectively preventing the axial movement of the reluctance rotor 23 during high-speed operation, ensuring the smoothness and accuracy of the entire processing process, and further improving the stability of the blade 21 rotation.

[0061] Furthermore, such as Figure 3 As shown, the bottom center of the body 231 is recessed to form a mounting groove 2311, and the fastener 25 is located in the mounting groove 2311.

[0062] By recessing the middle part of the bottom of the body 231 to form a mounting groove 2311, the fastener 25 is located in the mounting groove 2311, which effectively avoids the fastener 25 protruding from the bottom of the body 231, causing the fastener 25 to interfere with the bottom wall of the cutter holder 22 and generate friction noise, thus helping to further improve the stability of the rotation of the crushing device 2.

[0063] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
