Description

Technical Field

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

[0002] Existing food processors typically include a main unit, a detachable cup body mounted on the main unit, a pulverizing device housed within the cup body, and a motor located below the cup body and connected to the pulverizing device. When using the food processor, the user places the ingredients into the cup body, and the pulverizing device rotates at high speed driven by the brushless motor to process the ingredients. However, most existing motors are brushed motors, which generate significant noise and vibration during operation, resulting in a poor user experience. To improve processing results, most manufacturers use brushless motors instead of brushed motors. Brushless motors offer numerous advantages, including longer lifespan, lower vibration, lower noise, and no carbon powder pollution. To achieve control of brushless motors, as disclosed in the applicant's earlier application CN202322832062.6, a food processor driven by a brushless motor is installed inside the main unit of the food processor. The PCB board integrates a drive module for controlling the brushless motor's operation, as well as various electrical components, thus driving the brushless motor. Simultaneously, to achieve overall machine control and operation display, a control board is often installed on the main unit or the cup body. Users can select the type of food to be processed through the control board, which transmits signals to the brushless motor drive board, which then controls the brushless motor to achieve specific processing of specific foods. However, because two boards need to be installed inside the main unit, the brushless motor drive board and the control board need to be designed, manufactured, and assembled separately, which greatly limits the space layout inside the main unit. Especially with the current common practice of using flat brushless motors to achieve a flat main unit, the internal space is small, the installation layout is difficult, and the assembly steps are numerous and complex. Meanwhile, the brushless motor driver board and the control board need to be connected by a wiring harness. In the limited space of the host, it is very difficult to manage the wiring. In addition, the distance between the brushless motor driver board and the control board is far, resulting in low signal transmission efficiency and easy errors, which seriously affects the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a food processing machine with a simplified structure, which solves the problem of how to set up a brushless motor drive board and a control board to meet the flat spatial layout and improve the efficiency of signal transmission between the two in a food processing machine with a flat brushless motor to achieve a flat main unit.

[0004] To achieve the above objectives, this utility model provides a food processing machine with a simplified structure, including a main unit, a detachable cup body mounted on the main unit, a crushing device mounted inside the cup body, and a brushless motor mounted below the cup body and connected to the crushing device for transmission. The main unit also includes a brushless motor drive board for controlling the brushless motor and a control board for user operation. The brushless motor drive board and the control board are integrated to form a main control board.

[0005] This application utilizes a brushless motor, leveraging its characteristics to reduce noise during food processing. The brushless motor also features variable frequency control, allowing the food processor to adjust its speed based on different ingredients and processing conditions. This results in better and more thorough processing, improving the texture and flavor of the food. Furthermore, the brushless motor's smaller footprint contributes to a more compact internal structure, reducing the overall space required for storage.

[0006] Simultaneously, by incorporating a brushless motor drive board for controlling the brushless motor and a control board for user operation within the main unit, users can select the type of food to be processed via the control board. The control board then transmits signals to the brushless motor drive board, which in turn controls the brushless motor to achieve specific processing of specific foods, meeting user needs and enhancing the user experience. Furthermore, the brushless motor drive board and control board are integrated into a single main control board, achieving machine operation with a single board. This improves the spatial layout and assembly requirements of existing main units, especially for flattened main units, facilitating internal space arrangement and enhancing the compactness of the internal structure, reducing the overall machine's footprint, and making it easier for users to access and store. It also eliminates the assembly step of a separate board, improving assembly efficiency. Additionally, integrating the brushless motor drive board and control board onto the main control board reduces the number of components that need to be connected to the main unit, thereby reducing noise generated by the relative vibration between the main unit and the main control board during food processing. Furthermore, it eliminates the need for the wiring harness connecting the brushless motor drive board and the control board, which not only reduces costs but also further improves assembly efficiency. In addition, it shortens the relative distance between the brushless motor drive board and the control board, thereby shortening the signal transmission distance between the two, which helps to improve signal transmission efficiency, reduce the risk of errors, and improve the stability of the whole machine operation.

[0007] In a preferred implementation of a simplified food processing machine, the main control board includes an MCU module for controlling the brushless motor drive board and the control board.

[0008] By including an MCU module on the main control board, which is used to control the brushless motor drive board and the control board, compared to the existing method that requires setting up MCU modules on both the brushless motor drive board and the control board to achieve signal transmission, only one MCU module is needed to achieve data transmission between the brushless motor drive board and the control board. This eliminates the need for an MCU module, helps reduce the risk of data loss during data transmission, shortens the signal transmission distance, further improves signal transmission efficiency, and enhances the stability of the entire machine operation.

[0009] In a preferred embodiment of a simplified food processing machine, the main control board has a first control area and a second control area along its width direction, and the brushless motor drive board and the control board are respectively located in the first control area and the second control area.

[0010] By setting a first control area and a second control area along the width of the control board, and placing the brushless motor drive board and the control board in the first control area and the second control area respectively, the functional partitioning of the main control board is realized. This allows the brushless motor drive board and the control board to be grouped in different areas, thereby avoiding signal interference caused by different functional modules in adjacent areas, which could lead to errors on the main control board and help to further improve the stability of the main control board.

[0011] In a preferred embodiment of a simplified food processing machine, the control board includes a control module and a display module, with the display module isolated between the control module and the brushless motor drive board.

[0012] By configuring the control board to include both a control module and a display module, users can control the main control board through the control module and display the machine's operating status through the display module, meeting user needs. Simultaneously, the display module is isolated between the control module and the brushless motor drive board, further isolating them and preventing signal interference that could cause instability in the main control board. This contributes to improving the overall stability of the machine's operation.

[0013] In a preferred embodiment of a simplified food processing machine, the second control area includes a first area and a second area arranged along the length of the main control board. The main control board includes an MCU module for controlling a brushless motor drive board and a control board. The brushless motor drive board includes an EMC module, a power supply module, and a brushless drive module. The EMC module and the power supply module are located in the first area, and the brushless drive module and the MCU module are located in the second area.

[0014] By placing the EMC module and power module in the first area, the EMC module can directly suppress electromagnetic interference in the wires and power module, reducing the impact of the external electromagnetic environment on the electronic equipment and further improving its operational stability. Meanwhile, since the MCU is a high-frequency signal, placing the brushless drive module and MCU module in the second area shortens the transmission distance between their signals, thereby further improving the reliability of signal transmission and ensuring the stability of the entire machine's operation.

[0015] In a preferred embodiment of a simplified food processing machine, the main unit includes a main unit housing, the top wall of which is provided with a mounting surface for fixing the main control board, the mounting surface extending upwards and at an angle from the front end to the rear end of the main unit.

[0016] By providing a mounting surface on the top wall of the main unit housing to secure the main control board, the stability of the connection between the main control board and the main unit housing is ensured. Simultaneously, the mounting surface extends upwards and slopes from the front to the rear of the main unit, ensuring that the main control board is angled towards the user when using the food processor. This not only facilitates observation of the main control board but also better aligns with user operating habits, enhancing the user experience.

[0017] In a preferred embodiment of a simplified food processing machine, the brushless motor drive board is located on the front side of the control board, away from the main unit.

[0018] By placing the brushless motor drive board on the front side of the main control board, which is further away from the bottom wall of the main control board, the distance between the bottom wall of the main control board and the brushless motor drive board is greatly increased. This creates a larger heat dissipation space between them, allowing the heat generated by the brushless motor drive board during operation to be effectively dissipated in the space below. This helps improve the heat dissipation of the main control board, reduces its temperature rise, and avoids the situation where the temperature rise of the main control board leads to serious aging, thus helping to extend its service life.

[0019] In a preferred embodiment of a simplified food processing machine, the mounting surface has a perforated display and control area, the control board is located within the display and control area, and the brushless motor drive board is hidden inside the main unit housing.

[0020] By providing a perforated display and control area on the mounting surface, with the control board located within the display and control area and the brushless motor drive board hidden inside the main unit housing, the control board can be exposed through the display and control area, allowing users to directly observe and control it. At the same time, the brushless motor drive board is hidden, preventing its exposure from affecting the overall aesthetics of the machine.

[0021] In a preferred embodiment of a simplified food processing machine, the main unit includes a main unit housing, the top of which is recessed to form a receiving groove for accommodating a cup, and a receiving cavity located at the front end of the receiving groove is also formed inside the main unit housing, with the main control board disposed inside the receiving cavity.

[0022] By recessing the top of the main unit housing to form a receiving groove for accommodating the cup assembly, the cup can be effectively restrained after being installed on the main unit, improving the stability of the connection between the cup and the main unit. This prevents the cup from swinging excessively during food processing, thus avoiding noise or even interruption of food processing. Furthermore, a receiving cavity is formed inside the main unit housing at the front end of the receiving groove, and the main control board is housed within this cavity, ensuring the stability of the connection between the main control board and the main unit housing.

[0023] In a preferred embodiment of a simplified food processing machine, the receiving tank and the receiving cavity at least partially overlap laterally.

[0024] By aligning the receiving slot and the receiving cavity at least partially in the lateral direction, the lateral space within the main unit is effectively utilized. Compared to existing methods that place the receiving cavity below the receiving slot, this further compresses the axial dimension of the main unit, thereby lowering the center of gravity of the entire main unit and cup assembly. This effectively improves the stability of the entire machine during operation and further enhances the stability of the cup assembly during food processing. Simultaneously, it increases the contact area between the main unit and the tabletop, further improving the stability of the main unit. Attached Figure Description

Detailed Implementation

[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 4 As shown, this utility model provides a simplified food processing machine, including a main unit 4, a detachable cup body 1 mounted on the main unit 4, a crushing device 9 disposed inside the cup body 1, and a brushless motor 2 disposed below the cup body 1 and connected to the crushing device 9 in a transmission. The main unit 4 also includes a brushless motor drive board 52 for controlling the brushless motor 2 and a control board 51 for user operation. The brushless motor drive board 52 and the control board 51 are integrally disposed to form the main control board 5.

[0035] This application incorporates a brushless motor 2. Utilizing the characteristics of the brushless motor 2, the noise level during food processing is reduced, achieving noise reduction. Simultaneously, the brushless motor 2 is capable of frequency conversion control, allowing the food processor to adjust its output speed according to different ingredients and processing conditions. This results in better and more thorough processing, enhancing the texture and flavor of the food. Furthermore, the brushless motor 2 occupies less space, contributing to a more compact internal structure and reducing the overall footprint of the food processor, making it easier for users to store.

[0036] Meanwhile, by having a brushless motor drive board 52 for controlling the brushless motor 2 and a control board 51 for user operation in the main unit 4, the user can select the type of food to be processed by operating the control board 51. At the same time, the control board 51 transmits the signal to the brushless motor drive board 52, and then the brushless motor drive board 52 controls the brushless motor 2 to achieve specific processing of specific food, meet the user's needs, and improve the user experience. Meanwhile, the brushless motor drive board 52 and the control board 51 are integrated to form the main control board 5, realizing the integration of the brushless motor drive board 52 and the control board 51. The machine can be operated normally using a single main control board 5. This also improves the spatial layout and assembly requirements within the existing host 4, especially for the flat host 4. It facilitates the spatial layout within the host 4 and helps to improve the compactness of the internal structure of the host 4, reducing the space occupied by the whole machine. This makes it easier for users to pick up, put away, and store the machine, and eliminates the assembly step of a board, which helps to improve assembly efficiency. At the same time, the integration of the brushless motor drive board 52 and the control board 51 on the main control board 5 can reduce the number of components that need to be connected with the host 4, thereby reducing the noise generated by the relative vibration of the host 4 and the main control board 5 when the food processing machine is processing ingredients. Furthermore, it eliminates the need for the wiring harness connecting the brushless motor drive board 52 and the control board 51, which not only reduces costs but also further improves assembly efficiency. In addition, it shortens the relative distance between the brushless motor drive board 52 and the control board 51, thereby shortening the signal transmission distance between the two, which helps to improve signal transmission efficiency, reduce the risk of errors, and improve the stability of the whole machine operation.

[0037] It should be noted that this application does not specifically limit the placement of the brushless motor 2, such as... Figure 1 As shown, a cup holder 3 is also fixed below the cup body 1. The cup holder 3 and the cup body 1 enclose a mounting cavity to accommodate the brushless motor 2; alternatively, the brushless motor 2 can be fixed inside the main unit housing 41, which will not be described in detail here.

[0038] As a preferred embodiment of this application, such as Figure 4 As shown, the main control board 5 includes an MCU module 522, which is used to control the brushless motor drive board 52 and the control board 51.

[0039] By including an MCU module 522 on the main control board 5, and using the MCU module 522 to control the brushless motor drive board 52 and the control board 51, compared with the existing method that requires setting an MCU module 522 on both the brushless motor drive board 52 and the control board 51 to achieve signal transmission, only one MCU module 522 is needed to achieve data transmission between the brushless motor drive board 52 and the control board 51. This eliminates the need for an MCU module 522, helps reduce the risk of data loss during data transmission, shortens the signal transmission distance, further improves signal transmission efficiency, and enhances the stability of the entire machine operation.

[0040] It should be noted that this application does not specifically limit the placement of the brushless motor drive board 52 and the control board 51. As a preferred embodiment of this application, for example... Figure 4 As shown, the main control board 5 has a first control area 53 and a second control area 54 along its width direction, and the brushless motor drive board 52 and the control board 51 are respectively located in the first control area 53 and the second control area 54.

[0041] By providing a first control area 53 and a second control area 54 along its width direction, and placing the brushless motor drive board 52 and the control board 51 within the first control area 53 and the second control area 54 respectively, the functional partitioning of the main control board 5 is realized. This allows the brushless motor drive board 52 and the control board 51 to be grouped in different areas, thereby avoiding signal interference caused by different functional modules 522 in adjacent areas, which could lead to errors in the main control board 5 and further improve the stability of the main control board 5.

[0042] Furthermore, such as Figure 4 As shown, the control board 51 includes a control module 511 and a display module 512, with the display module 512 isolated between the control module 511 and the brushless motor drive board 52.

[0043] By configuring the control board 51 to include a control module 511 and a display module 512, users can control the main control board 5 through the control module 511 and display the machine's operating status through the display module 512, thus meeting user needs. Simultaneously, the display module 512 is isolated between the control module 511 and the brushless motor drive board 52, further isolating them and preventing signal interference that could cause instability in the main control board 5. This helps to further improve the overall stability of the machine's operation.

[0044] As a preferred embodiment, such as Figure 4 As shown, the second control area 54 includes a first area 541 and a second area 542 arranged along the length of the main control board 5. The main control board 5 includes an MCU module 522 for controlling the brushless motor drive board 52 and the control board 51. The brushless motor drive board 52 includes an EMC module 522, a power module 521 and a brushless drive module 523. The EMC module 522 and the power module 521 are located in the first area 541, and the brushless drive module 523 and the MCU module 522 are located in the second area 542.

[0045] By placing the EMC module 522 and the power module 521 in the first region 541, the EMC module 522 can directly suppress electromagnetic interference in the wires and the power module 521, reducing the influence of the external electromagnetic environment on the electronic equipment and further improving the working stability. At the same time, since the MCU is a high-frequency signal, placing the brushless drive module 523 and the MCU module 522 in the second region 542 shortens the transmission distance between the two signals, thereby further improving the reliability of signal transmission and ensuring the stability of the whole machine operation.

[0046] As a preferred embodiment of this application, such as Figure 2 As shown, the host 4 includes a host housing 41. The top wall of the host housing 41 is provided with a mounting surface 412 for fixing the main control board 5. The mounting surface 412 extends upward from the front end to the rear end of the host 4.

[0047] By providing a mounting surface 412 on the top wall of the main housing 41 for fixing the main control board 5, the main control board 5 is secured, ensuring the stability of the connection and fit between the main control board 5 and the main housing 41. Simultaneously, the mounting surface 412 extends upwards and at an angle from the front end to the rear end of the main unit 4, ensuring that the main control board 5 is tilted towards the user when using the food processor. This not only facilitates observation of the main control board 5 but also better aligns with user operating habits, enhancing the user experience.

[0048] Specifically, such as Figure 2 , Figure 3 As shown, a focusing bracket 6 is also provided between the main control board 5 and the mounting surface 412. When installing the main control board 5, screws 8 pass through the main control board 5 and the focusing bracket 6 and are fastened to the mounting surface 412 to achieve the installation and fixation of the main control board 5. At the same time, a face sticker 7 is attached to the outside of the mounting surface 412 to protect the main control board 5.

[0049] Furthermore, such as Figure 2 As shown, the brushless motor drive board 52 is located on the front side of the control board 51 away from the host 4.

[0050] By placing the brushless motor drive board 52 on the front side of the main control board 51, which is further away from the bottom wall of the main housing 41, the distance between the bottom wall of the main housing 41 and the brushless motor drive board 52 is greatly increased. This creates a larger heat dissipation space between them, allowing the heat generated by the brushless motor drive board 52 during operation to be effectively dissipated in the space below. This helps improve the heat dissipation effect of the main control board 5, reduces its temperature rise, and avoids the situation where the temperature rise of the main control board 5 is significant, leading to severe aging. This helps to extend its service life.

[0051] As a preferred embodiment, such as Figure 3As shown, the mounting surface 412 has a hollowed-out display control area, the control board 51 is located in the display control area, and the brushless motor drive board 52 is hidden inside the main unit housing 41.

[0052] By providing a hollowed-out display control area on the mounting surface 412, with the control board 51 located within the display control area and the brushless motor drive board 52 hidden inside the main unit housing 41, the control board 51 can be exposed through the display control area, allowing users to directly observe and control it. At the same time, the brushless motor drive board 52 is hidden, preventing its exposure from affecting the overall aesthetics of the machine.

[0053] As a preferred embodiment of this application, such as Figure 2 As shown, the host 4 includes a host housing 41, the top of the host housing 41 is recessed to form a receiving groove 31 for receiving the cup 1, and a receiving cavity 413 located at the front end of the receiving groove 31 is also formed inside the host housing 41, and the main control board 5 is disposed in the receiving cavity 413.

[0054] By recessing the top of the main housing 41 to form a receiving groove 31 for accommodating the cup body 1 assembly, the cup body 1 can be effectively limited by the receiving groove 31 after being installed on the main unit 4, improving the stability of the connection and cooperation between the cup body 1 and the main unit 4, thereby avoiding large swinging of the cup body 1 during food processing, which could cause noise or even interruption of food processing. Furthermore, a receiving cavity 413 is formed inside the main housing 41 at the front end of the receiving groove 31, and the main control board 5 is disposed within the receiving cavity 413, enabling the installation and fixation of the main control board 5 and ensuring the stability of the connection and cooperation between the main control board 5 and the main housing 41.

[0055] Furthermore, such as Figure 2 As shown, the receiving groove 31 and the receiving cavity 413 at least partially overlap in the lateral direction.

[0056] By aligning the receiving groove 31 and the receiving cavity 413 at least partially in the lateral direction, the lateral space within the main unit 4 is effectively utilized. Compared to the existing method of placing the receiving cavity 413 below the receiving groove 31, the axial dimension of the main unit 4 can be further compressed, thereby lowering the center of gravity height of the entire main unit 4 and the cup body 1 assembly. This effectively improves the stability of the entire machine during operation and further enhances the stability of the cup body 1 assembly during food processing. Simultaneously, it increases the contact area between the main unit 4 and the tabletop, further improving the stability of the main unit 4.
