Description

Technical Field

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

[0002] Existing food processors typically include a main unit with a motor and a cup body located above the motor, containing a pulverizing blade. When using the food processor, the user places the food into the cup body, and the pulverizing blade rotates at high speed driven by the motor to process the food. With the increasing demand for portability of food processors when traveling, most manufacturers have produced miniaturized, portable models. For example, the applicant's earlier patent application CN214549067U discloses a portable food processor shaped like a cup with a lid. Users can secure the lid to the cup body to seal the pulverizing chamber when carrying it. To heat the food inside the cup, a heating plate is located below the cup body, and the motor is fixed below the heating plate. The motor is secured by an upward-extending support base on the bottom wall of the main unit's outer casing. The bottom of the motor is supported and fixed to the support base, while the top is positioned through a clearance formed in the center of the heating plate, achieving a precise positioning of the entire motor. However, with this type of motor installation, the top is positioned using the heating plate as the reference point, while the bottom is positioned using the outer casing of the main unit. The different positioning references and the large assembly error between the outer casing and the heating plate cause the top and bottom of the motor to be out of alignment. This results in a large sway when the motor shaft rotates, causing significant vibration and noise in the entire machine, which seriously affects the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a portable food processing machine to solve the problem that the positioning reference of the top and bottom of the motor in the existing portable food processing machine is inconsistent, which causes the top and bottom of the motor to be not on the same vertical line, resulting in the shaft easily wobbling when rotating, thus causing the whole machine to vibrate and generate noise.

[0004] To achieve the above objectives, this utility model provides a portable food processor, including a main unit with a motor and a grinding cup located above the main unit. The grinding cup includes a cup body with a grinding chamber and a cup lid that is detachably fitted onto the cup body. The grinding cup is vertically penetrating and its bottom end is fixed to the top of the main unit. The main unit includes a shell with an open top and a heating plate fixed to the open part of the shell. The motor includes a stator, a rotor inside the stator, a rotating shaft, and a lower end cover. The stator includes a stator coil, and the rotor includes a permanent magnet that cooperates with the stator coil. The heating plate has a clearance opening for the rotating shaft to pass through. The heating plate has multiple downwardly extending positioning posts that surround the outside of the stator, and the positioning posts are circumferentially spaced along the central axis of the clearance opening. The stator and rotor are respectively assembled below the heating plate, and the side wall of the stator abuts radially against each positioning post. The lower end cover is connected to the bottom end of the positioning post to position the stator and rotor.

[0005] This application simplifies the overall structure by directly fixing the heating plate to the open part of the outer casing, making the heating plate serve as the top wall of the main unit and the bottom wall of the grinding chamber. This significantly improves the compactness of the overall structure, especially the reduction in axial dimensions, making the food processor more portable. The heating plate also features multiple downward-extending positioning posts surrounding the stator, spaced circumferentially along the central axis of the clearance opening. The stator and rotor are assembled below the heating plate, with the stator sidewalls radially abutting against each positioning post. Specifically, when assembling the motor onto the heating plate, the operator first inserts the stator between the positioning posts, ensuring precise positioning and alignment of the stator with the central axis of the clearance opening. Then, the rotor is placed inside the stator, and alignment with the central axis of the clearance opening is achieved through the interaction of the rotating shaft and the clearance opening. Finally, the lower end cover is attached to the bottom of the positioning posts. The lower end cover is positioned using a positioning post as the locating reference, and the positioning post in turn uses the clearance opening as the locating reference. Therefore, the lower end cover also uses the clearance opening as its locating reference. In summary, during motor assembly, the stator, rotor, shaft, and lower end cover are all positioned using the clearance opening as the locating reference, ensuring the concentricity of the entire motor assembly. This results in higher coaxiality and stronger stability during high-speed motor operation, effectively preventing vibration and noise caused by low coaxiality during motor rotation. This contributes to improving the overall machine's working stability and reducing noise generation, enhancing the user experience. Furthermore, by directly fixing the stator and rotor below the heating plate using the lower end cover, the structure of the upper end cover is eliminated, further simplifying the overall structure and helping to further reduce axial space. This allows the entire machine to maintain high efficiency while being more lightweight and portable, meeting the modern user's pursuit of a convenient lifestyle.

[0006] In a preferred embodiment of a portable food processing machine, each positioning column is provided with a positioning surface facing the stator side, and the stator sidewall abuts against each positioning surface.

[0007] By providing a positioning surface facing the stator side on each positioning post, and having the stator sidewall abut against each positioning surface, the positioning surface can precisely support the stator sidewall after the stator is installed between the positioning posts, thus achieving the alignment and centering of the stator. This ensures that the central axis of the stator is aligned with the central axis of the clearance opening, which helps to further improve the coaxiality and stability of the stator and reduce vibration and noise during operation.

[0008] In a preferred embodiment of a portable food processor, the positioning surface is configured to conform to the stator sidewall.

[0009] By setting the positioning surface to conform to the stator sidewall, the positioning surface and the stator sidewall are perfectly matched, so as to achieve precise positioning of the positioning surface in the radial direction of the stator, enhance the support effect, further improve the installation accuracy of the stator, and at the same time achieve effective positioning of the stator, ensuring smoother operation and further improving the stability of the whole machine.

[0010] In a preferred embodiment of a portable food processor, the positioning post is recessed into the outer wall of the stator side to form a positioning surface, and a limiting surface is formed above the positioning surface, the limiting surface abutting against the top wall of the stator.

[0011] By recessing the positioning post into the outer wall of the stator to form a positioning surface, and forming a limiting surface above the positioning surface, the limiting surface abuts against the top wall of the stator. After the stator is assembled, the positioning surface achieves radial positioning of the stator, ensuring the coaxiality of the stator and the clearance opening. At the same time, the limiting surface can also achieve axial positioning of the stator, thereby ensuring the accuracy of the stator's axial position. This dual positioning function of the stator helps to further improve the installation accuracy and stability of the stator, ensuring that the motor is more stable when running at high speed.

[0012] In a preferred embodiment of a portable food processor, at least three positioning posts are provided, and the positioning posts are evenly spaced along the circumferential direction of the stator.

[0013] By providing at least three positioning posts with evenly spaced intervals along the circumference of the stator, the stator can be evenly supported and positioned in three directions, thereby further improving the coaxiality of the stator and the clearance opening. This not only enables radial positioning of the stator but also effectively prevents lateral displacement of the stator, ensuring the stability of the stator position and contributing to further improving the overall stability of the machine operation.

[0014] In a preferred embodiment of a portable food processor, at least two positioning posts are arranged symmetrically along the radial direction of the stator.

[0015] By setting at least two positioning posts to be arranged symmetrically along the radial direction of the stator, the support of the positioning posts on the stator in the radial direction is more balanced. The two positioning posts that are opposite to each other in the radial direction can cause the stator to be subjected to opposite forces in the radial direction, thereby causing the stator to move towards the center of the two positioning posts. This enables the stator to be precisely aligned with the central axis of the clearance opening, which helps to further improve the radial positioning accuracy of the stator.

[0016] In a preferred embodiment of a portable food processor, the radius of the circle containing the innermost end of each positioning post on the side that abuts against the stator is smaller than the radius of the stator sidewall, so that the stator and positioning post are in an interference fit.

[0017] By making the radius of the innermost circle of each positioning post on the side that abuts against the stator smaller than the radius of the stator sidewall, an interference fit is achieved between the stator and the positioning posts. On the one hand, this makes the positioning of the positioning posts on the stator more stable, which not only improves the coaxiality of the stator and the clearance opening, but also ensures the stability of the stator's position, preventing it from shifting or vibrating during operation, and helping to further reduce noise generation. On the other hand, when assembling the motor, the operator can directly clamp the motor between the positioning posts and leave their hands, achieving axial positioning of the stator without the need for the lower end cover, making subsequent assembly more convenient and faster, and helping to improve assembly efficiency.

[0018] In a preferred embodiment of a portable food processor, the lower end cover includes a body supported below the stator and a surrounding rib extending upward from the outer periphery of the body. The outer wall of the surrounding rib is provided with a mounting post that is axially aligned with and fixedly connected to the positioning post.

[0019] By including a body supporting the stator below and surrounding ribs extending upwards from the outer periphery of the body, the lower end cover effectively supports the stator, ensuring the stability of the stator's axial position. Simultaneously, the surrounding ribs further position the stator radially. Combined with the positioning pins, this achieves a dual radial positioning effect for the stator, ensuring the coaxiality of the stator and the clearance opening. Furthermore, the outer wall of the surrounding ribs is equipped with mounting pins that are axially aligned with and fixed to the positioning pins. This allows the lower end cover to be axially fixed to the positioning pins via the mounting pins, ensuring the stability of the lower end cover's position.

[0020] In a preferred embodiment of a portable food processing machine, the inner wall of the rib abuts against the outer wall of the stator.

[0021] By setting the inner wall of the rib to abut against the outer wall of the stator, the radial positioning effect of the lower end cover on the stator is further improved, ensuring that the stator maintains a precise axial and radial position when running at high speed, effectively reducing vibration and noise, and improving the stability of the whole machine operation.

[0022] In a preferred embodiment of a portable food processor, an installation gap is formed between each positioning column, and a temperature controller is installed within the installation gap.

[0023] By incorporating a thermostat within the installation gap, the space beneath the heating plate is utilized to its fullest potential, which helps to further enhance the compactness of the overall structure. At the same time, the thermostat precisely regulates the temperature to prevent overheating or underheating, ensuring that the food is heated evenly. Attached Figure Description

[0032] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0033] 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.

[0034] like Figures 1 to 5 As shown, this utility model provides a portable food processor, including a main unit 3 with a motor 4 inside and a grinding cup located above the main unit 3. The grinding cup includes a cup body 2 with a grinding chamber and a cup lid 1 detachably covering the cup body 2. The grinding cup is vertically through-hole shaped, and its bottom end is fixed to the top of the main unit 3. The main unit 3 includes a shell 31 with an open top and a heating plate 32 fixed to the open part of the shell 31. The motor 4 includes a stator 41, a rotor 42 disposed in the stator 41, a rotating shaft 43, and a lower end cover 44. The device includes a stator 41 coil and a rotor 42 including a permanent magnet that cooperates with the stator 41 coil. The heating plate 32 is provided with a clearance opening through which the rotating shaft 43 passes. The heating plate 32 is provided with a plurality of downwardly extending positioning posts 321 surrounding the outside of the stator 41. The positioning posts 321 are circumferentially spaced along the central axis of the clearance opening. The stator 41 and the rotor 42 are respectively assembled below the heating plate 32, and the side wall of the stator 41 abuts radially with each positioning post 321. The lower end cover 44 is connected to the bottom end of the positioning post 321 to position the stator 41 and the rotor 42.

[0035] This application simplifies the overall structure by directly fixing the heating plate 32 to the open portion of the outer casing 31, making the heating plate 32 serve as the top wall of the main unit 3 and the bottom wall of the grinding chamber. This significantly improves the overall compactness of the machine, particularly reducing the axial dimension, and making it easier for users to carry the food processor. Simultaneously, the heating plate 32 has multiple downward-extending positioning posts 321 surrounding the stator 41. These positioning posts 321 are spaced circumferentially along the central axis of the clearance opening. The stator 41 and rotor 42 are assembled below the heating plate 32, with the sidewall of the stator 41 radially abutting against each positioning post 321. Specifically, when assembling the motor 4 onto the heating plate 32, the operator first inserts the stator 41 between the positioning posts 321, ensuring precise positioning of the stator 41 and alignment with the central axis of the clearance opening. Then, the rotor 42 is placed inside the stator 41, and the rotor 42 is aligned with the central axis of the clearance opening through the cooperation of the rotating shaft 43. Finally,... The lower end cover 44 is connected to the bottom end of the positioning post 321. The lower end cover 44 uses the positioning post 321 as the positioning reference, and the positioning post 321 uses the clearance opening as the reference. Thus, the lower end cover 44 also uses the clearance opening as the positioning reference. In summary, during the assembly of the motor 4, the stator 41, rotor 42, shaft 43, and lower end cover 44 are all positioned with the clearance opening as the reference, ensuring the concentricity of the entire motor 4 assembly. This results in higher coaxiality and stronger stability of the motor 4 during high-speed operation, effectively avoiding vibration and noise caused by low coaxiality during motor 4 rotation. This helps improve the overall working stability of the machine and reduce noise generation, enhancing the user experience. In addition, by directly fixing the stator 41 and rotor 42 below the heating plate 32 through the lower end cover 44, the structure of the upper end cover is eliminated, further simplifying the overall structure and helping to further compress the axial space. This makes the whole machine lighter and more portable while maintaining high efficiency, meeting the modern user's pursuit of a convenient life.

[0036] As a preferred embodiment of this application, such as Figure 3 As shown, each positioning post 321 is provided with a positioning surface 3211 facing the stator 41, and the side wall of the stator 41 abuts against each positioning surface 3211.

[0037] By providing a positioning surface 3211 facing one side of the stator 41 for each positioning post 321, and having the side wall of the stator 41 abut against each positioning surface 3211, the positioning surface 3211 can accurately support the side wall of the stator 41 after the stator 41 is installed between the positioning posts 321, thereby achieving the alignment and centering of the stator 41 and ensuring that the central axis of the stator 41 is aligned with the central axis of the clearance opening. This helps to further improve the coaxiality and stability of the stator 41 and reduce vibration and noise during operation.

[0038] Furthermore, such as Figure 3As shown, the positioning surface 3211 is configured to conform to the side wall of the stator 41. Specifically, if the side wall of the stator 41 is a flat surface, the positioning surface 3211 is also a flat surface; or if the side wall of the stator 41 is an arc-shaped surface, the positioning surface 3211 is also another arc-shaped surface that matches the arc-shaped surface. It is only necessary to ensure that the positioning surface 3211 and the side wall of the stator 41 are completely fitted together.

[0039] By setting the positioning surface 3211 to conform to the side wall of the stator 41, the positioning surface 3211 and the side wall of the stator 41 are perfectly matched, so as to achieve precise radial positioning of the positioning surface 3211 on the stator 41, enhance the support effect, further improve the installation accuracy of the stator 41, and at the same time achieve effective positioning of the stator 41, ensuring smoother operation and further improving the stability of the whole machine operation.

[0040] As a preferred embodiment, such as Figure 3 As shown, the outer wall of the positioning post 321 facing the stator 41 is recessed to form a positioning surface 3211, and a limiting surface 3212 is formed above the positioning surface 3211. The limiting surface 3212 abuts against the top wall of the stator 41.

[0041] By recessing the outer wall of the positioning post 321 toward the stator 41 to form a positioning surface 3211, and forming a limiting surface 3212 above the positioning surface 3211, the limiting surface 3212 abuts against the top wall of the stator 41, so that after the stator 41 is assembled in place, the positioning surface 3211 achieves radial positioning of the stator 41, ensuring the coaxiality of the stator 41 and the clearance opening. At the same time, the limiting surface 3212 can also achieve axial positioning of the stator 41, thereby ensuring the accuracy of the axial position of the stator 41, realizing the dual positioning function of the stator 41, which helps to further improve the installation accuracy and stability of the stator 41, and ensures that the motor 4 is more stable when running at high speed.

[0042] It should be noted that this application does not specifically limit the number of positioning posts 321. As a preferred embodiment of this application, such as... Figure 5 As shown, at least three positioning posts 321 are provided, and the positioning posts 321 are evenly spaced along the circumference of the stator 41. More preferably, as shown... Figure 5 As shown, there are three positioning posts 321, and the interval angle between two adjacent positioning posts 321 is 120°; of course, it can also be set to four, and the interval angle between two adjacent positioning posts 321 is 90°; or it can be set to five, and the interval angle between two adjacent positioning posts 321 is 72°; or it can be set to more, which will not be elaborated here.

[0043] By providing at least three positioning posts 321, and arranging them evenly spaced along the circumference of the stator 41, the stator 41 can be evenly supported and positioned in three directions, thereby further improving the coaxiality of the stator 41 and the clearance opening. This not only enables radial positioning of the stator 41 but also effectively prevents the stator 41 from shifting laterally, ensuring the stability of the stator 41's position and helping to further improve the stability of the entire machine's operation.

[0044] In a preferred embodiment of this application, at least two positioning posts 321 are arranged symmetrically along the radial direction of the stator 41. More preferably, in this embodiment, the number of positioning posts 321 is not less than four and the number is an even number.

[0045] By setting at least two positioning posts 321 to be arranged symmetrically in the radial direction of the stator 41, the support of the positioning posts 321 on the stator 41 in the radial direction is more balanced. The two positioning posts 321 that are radially opposite can make the stator 41 be subjected to opposite forces in the radial direction, thereby causing the stator 41 to move towards the center of the two positioning posts 321, and thus enabling the stator 41 to be precisely aligned with the central axis of the clearance opening, which helps to further improve the radial positioning accuracy of the stator 41.

[0046] As a preferred embodiment of this application, such as Figure 3 As shown, the radius of the circle containing the innermost end of each positioning post 321 on the side that abuts against the stator 41 is smaller than the radius of the side wall of the stator 41, so that the stator 41 and the positioning post 321 are interference fit.

[0047] By making the radius of the innermost circle of each positioning post 321 that abuts against the stator 41 smaller than the radius of the side wall of the stator 41, the stator 41 and the positioning post 321 are interference-fitted. On the one hand, this makes the positioning of the positioning post 321 on the stator 41 more stable, which not only improves the coaxiality of the stator 41 and the clearance opening, but also ensures the stability of the stator 41's position, preventing it from shifting or vibrating during operation, and helping to further reduce noise generation. On the other hand, when assembling the motor 4, the operator can directly clamp the motor 4 between the positioning posts 321 and then leave the operator's hands, achieving axial positioning of the stator 41 without the need for the lower end cover 44, making subsequent assembly more convenient and faster, and helping to improve assembly efficiency.

[0048] As a preferred embodiment of this application, such as Figure 3 As shown, the lower end cover 44 includes a body 442 supported below the stator 41 and a surrounding rib 441 extending upward from the outer periphery of the body 442. The outer wall of the surrounding rib 441 is provided with a mounting post 4411 that is axially aligned with and fixedly connected to the positioning post 321.

[0049] By including a body 442 supporting the stator 41 and a surrounding rib 441 extending upward from the outer periphery of the body 442, the body 442 of the lower end cover 44 effectively supports the stator 41, ensuring the axial stability of the stator 41. Simultaneously, the surrounding rib 441 further positions the stator 41 radially. Combined with the positioning post 321, this achieves a dual radial positioning effect for the stator 41, ensuring the coaxiality of the stator 41 and the clearance opening. Furthermore, the outer wall of the surrounding rib 441 is provided with a mounting post 4411 that is axially aligned with and fixedly connected to the positioning post 321. This allows the lower end cover 44 to be axially fixedly connected to the positioning post 321 via the mounting post 4411, ensuring the stability of the lower end cover 44's position.

[0050] Furthermore, such as Figure 3 As shown, the inner wall of the surrounding reinforcement 441 abuts against the outer wall of the stator 41.

[0051] By setting the inner wall of the rib 441 to abut against the outer wall of the stator 41, the radial positioning effect of the lower end cover 44 on the stator 41 is further improved, ensuring that the stator 41 maintains a precise axial and radial position when running at high speed, effectively reducing vibration and noise, and improving the stability of the whole machine operation.

[0052] As a preferred embodiment of this application, such as Figure 5 As shown, there is an installation gap between each positioning post 321, and a temperature controller 5 is installed in the installation gap.

[0053] By incorporating a thermostat 5 within the installation gap, the space beneath the heating plate 32 is utilized to its fullest potential, which helps to further enhance the compactness of the overall structure. At the same time, the thermostat 5 precisely regulates the temperature to avoid overheating or underheating, ensuring that the food is heated evenly.

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.
