Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with good heat dissipation. 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 these issues, some manufacturers install a driven disk at the bottom of the mixing unit and an active disk on the motor shaft. After the cup is installed, the active and driven disks magnetically engage to transmit torque, eliminating the need for drilling holes in the bottom wall and removing cleaning dead zones, allowing for thorough cleaning. However, when the active disk drives the driven disk, magnetic eddy currents are generated between them. The bottom wall of the cup heats up due to these eddy currents, leading to localized overheating, especially when the bottom wall is metal. This further increases the temperature of both the active and driven disks, significantly reducing their magnetic attraction. This greatly diminishes the torque transmission from the active disk to the driven disk, sometimes even preventing effective attraction, hindering food processing and severely impacting the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a food processing machine with good heat dissipation, in order to solve the problem of how to avoid the temperature rise and magnetic attraction decrease of the active and passive disks when they rotate, which is caused by the magnetic eddy currents generated when the active and passive disks rotate, under the premise that the rotation of the stirring blade is achieved by setting an active disk and a passive disk to reduce the cleaning dead corner.

[0005] To achieve the above objectives, this utility model provides a food processing machine with good heat dissipation, including a main unit with a built-in motor and a detachable cup body located above the main unit and containing a stirring assembly. The stirring assembly includes a stirring blade and a driven disk that is drivenly connected to the stirring blade. A cup bottom cover is provided at the bottom of the cup body, and the cup bottom cover and the cup body enclose a grinding chamber that accommodates the stirring assembly. An active disk that magnetically engages with the driven disk is provided at the top of the motor shaft of the motor, and a heat dissipation fan is provided at the bottom of the active disk.

[0006] This application sets the stirring assembly to include a stirring blade and a driven disk that is driven by the stirring blade. The motor shaft has an active disk that magnetically engages with the driven disk. When the user places the cup on the main unit, the active disk and the driven disk magnetically engage. When the motor drives the active disk to rotate, the active disk drives the driven disk to rotate through the magnetic force with the driven disk, thereby causing the stirring blade to rotate. Compared with the existing method that requires upper and lower connectors to transmit torque, this eliminates the need for holes at the bottom of the cup, thus eliminating the need for seals and bearings, simplifying the cup structure, reducing cleaning dead spots, and making it easier for users to clean the cup.

[0007] Meanwhile, the bottom of the active disk is equipped with a cooling fan. When the motor drives the active disk to rotate, the cooling fan rotates accordingly, thereby driving the airflow around the active disk. This allows more airflow to pass over the active disk, effectively cooling it down. This effectively prevents the magnetic attraction from decreasing due to high temperature during torque transmission between the active and driven disks, which could lead to reduced torque transmission force or even failure of magnetic attraction to drive the mixing blades. This ensures the stability of the entire machine and guarantees the processing effect on the food.

[0008] In a preferred embodiment of a food processing machine with good heat dissipation, the active disk includes a magnet bracket fixedly connected to the motor shaft and an active magnet fixed above the magnet bracket, with heat dissipation fan blades formed on the bottom wall of the magnet bracket.

[0009] By including the active disk and the magnet bracket fixedly connected to the motor shaft and the active magnet fixed above the magnet bracket, and forming the heat dissipation fan blades on the bottom wall of the magnet bracket, the magnet bracket can be fixedly connected to the motor shaft while also forming the heat dissipation fan blades. This dual-purpose design eliminates the need for additional structural components to form the heat dissipation fan blades, which helps to simplify the overall structure of the machine and reduce the space occupied by the active disk.

[0010] In a preferred embodiment of a food processing machine with good heat dissipation, the main unit includes a housing for accommodating a motor, and the top of the housing is provided with a clearance opening for the motor shaft to extend out, and a flow gap is provided between the clearance opening and the motor shaft.

[0011] By providing a flow gap between the clearance port and the motor shaft, the airflow can enter the host or flow out from the host as the cooling fan rotates with the active disk. This increases the flow rate and speed of airflow near the active disk, thereby increasing the airflow near the active disk per unit time. This further enhances the cooling effect on the active disk, reducing its temperature rise. At the same time, it can also drive the airflow inside the host, thereby cooling various components inside the host. This effectively prevents the equipment performance from degrading due to high temperature, ensuring long-term efficient operation of the entire machine. It achieves a dual cooling effect of one cooling fan for both the active disk and various components inside the host, improving the overall cooling efficiency of the equipment.

[0012] In a preferred embodiment of a food processing machine with good heat dissipation, the width L of the flow gap satisfies: 5mm≤L≤15mm.

[0013] By setting the width L of the overcurrent gap to satisfy: 5mm≤L≤15mm, we can avoid the situation where the width of the overcurrent gap is too small, which would cause the airflow to be obstructed and result in poor gas flow, thus leading to poor heat dissipation of the active disk. At the same time, we can also avoid the situation where the width of the overcurrent gap is too large, which would result in an excessive gap between the motor shaft and the clearance port, allowing external dust and impurities to easily enter the host, affecting the stability of the equipment operation and its service life.

[0014] In a preferred embodiment of a food processing machine with good heat dissipation, the heat dissipation fan is a centrifugal fan, and the bending direction of the heat dissipation fan is the same as the rotation direction of the active disk.

[0015] By setting the cooling fan blades as centrifugal fan blades, and the bending direction of the cooling fan blades is the same as the rotation direction of the active disk, the cooling fan blades can guide the airflow from bottom to top when the active disk rotates. This allows the airflow inside the host to be driven by the cooling fan blades, thereby achieving heat dissipation for various components inside the host and ensuring that the whole machine still maintains high-efficiency operation in high-temperature environments, further improving heat dissipation efficiency.

[0016] In a preferred embodiment of a food processing machine with good heat dissipation, the main unit includes a housing that houses the motor. The housing is provided with a vent, through which airflow driven by the cooling fan blades is drawn in or discharged.

[0017] By incorporating ventilation openings in the casing, the airflow driven by the cooling fan is drawn in or expelled through these openings, effectively preventing the formation of localized high temperatures due to the enclosed space near the active disks, which would otherwise hinder the flow of external air. This allows for convection between the internal airflow and the external cool air, further enhancing the cooling effect on the active disks. Simultaneously, while cooling the active disks, it also promotes airflow within the host, thereby cooling various components within the host. This ensures that the entire machine maintains efficient operation even in high-temperature environments, extending the device's lifespan and improving the user experience.

[0018] In a preferred embodiment of a food processing machine with good heat dissipation, the motor is located on the airflow path driven by the cooling fan blades.

[0019] By placing the motor in the airflow path driven by the cooling fan, the motor can be directly cooled by the airflow during operation, effectively reducing the motor temperature and preventing performance degradation or damage caused by overheating, thus further ensuring the stable operation and long-term durability of the food processing machine.

[0020] In a preferred embodiment of a food processing machine with good heat dissipation, the main unit is further provided with an air guide shroud covering the outside of the motor, with one end of the air guide shroud connected to the ventilation port and the other end connected to the bottom of the active disk.

[0021] By installing an air guide shroud inside the main unit that covers the outside of the motor, with one end of the air guide shroud connected to the ventilation port and the other end connected to the bottom of the active disk, the airflow driven by the cooling fan can be guided and concentrated by the air guide shroud to directly act on the motor and the active disk, forming a directional cooling path. This effectively improves the heat dissipation efficiency of the motor and disk, ensuring that the equipment maintains stable performance under high load and extending its service life.

[0022] In a preferred embodiment of a food processing machine with good heat dissipation, the motor is located upstream of the airflow path relative to the active disk.

[0023] By setting the motor upstream of the active disk relative to the active disk, the airflow driven by the cooling fan can pass through the motor first and then through the active disk. This restricts the airflow to pass through the lower temperature area before cooling the higher temperature active disk, ensuring cooling efficiency. It avoids the situation where the airflow passes through the active disk first and then through the motor, resulting in the airflow temperature being higher when passing through the active disk and being carried to the motor, causing the motor's cooling effect to be low or even further increasing the temperature.

[0024] In a preferred embodiment of a food processing machine with good heat dissipation, the main unit is provided with a mounting platform on top, the cup body is mounted on the mounting platform, the mounting platform is provided with an annular rib extending upward and positioned to cooperate with the cup body, and the annular rib is provided with a communication channel connecting the inner side of the annular rib to the outside.

[0025] By incorporating an upward-extending annular rib on the mounting platform that aligns with the cup body, the host is securely positioned on the cup body, ensuring stable connection between the cup body and the host. This prevents the cup body from detaching due to vibration or improper operation, improving safety. Simultaneously, the annular rib has a connecting channel between its inner side and the outside environment, allowing for communication between the inside of the rib and the outside. This ensures that when the cooling fan drives airflow, the air inside the annular rib can convect with the outside cool air, effectively reducing the temperature inside the annular rib and further enhancing the heat dissipation effect on the active disk.

[0035] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0036] 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.

[0037] like Figures 1 to 6 As shown, this utility model provides a food processor with good heat dissipation, including a main unit 6 with a built-in motor 7 and a detachable cup body 1 located above the main unit 6 and having a built-in stirring assembly. The stirring assembly includes a stirring blade 3 and a driven disk 4 that is drivenly connected to the stirring blade 3. The bottom end of the cup body 1 is provided with a cup bottom cover 2, and the cup bottom cover 2 and the cup body 1 enclose a grinding chamber 11 for accommodating the stirring assembly. The top end of the motor shaft 71 of the motor 7 is provided with an active disk 5 that magnetically engages with the driven disk 4, and the bottom of the active disk 5 is provided with a heat dissipation fan 53.

[0038] This application sets the stirring assembly to include a stirring blade 3 and a driven disk 4 that is driven by the stirring blade 3. The motor shaft 71 of the motor 7 is provided with an active disk 5 that magnetically engages with the driven disk 4. When the user places the cup 1 on the main unit 6, the active disk 5 and the driven disk 4 magnetically engage. When the motor 7 drives the active disk 5 to rotate, the active disk 5 drives the driven disk 4 to rotate through the magnetic force with the driven disk 4, thereby causing the stirring blade 3 to rotate. Compared with the existing method that requires setting up upper and lower connectors to achieve torque transmission, this eliminates the need for opening holes at the bottom of the cup 1, thereby eliminating the need for seals and bearings, which helps to simplify the structure of the cup 1 and reduces cleaning dead corners, making it easier for the user to clean the cup 1.

[0039] Meanwhile, the bottom of the active disk 5 is equipped with a heat dissipation fan 53, so that when the motor 7 drives the active disk 5 to rotate, the heat dissipation fan 53 rotates accordingly, thereby driving the airflow around the active disk 5. This allows the airflow to pass more over the active disk 5 to effectively dissipate heat and cool it down. This effectively avoids the situation where the magnetic attraction force decreases due to high temperature during the torque transmission between the active disk 5 and the driven disk 4, resulting in a decrease in the torque transmission force between the active disk 5 and the driven disk 4 or even failure of the magnetic attraction to drive the stirring blade 3 to rotate. This ensures the stability of the whole machine operation and ensures the processing effect on the food.

[0040] As a preferred embodiment of this application, such as Figure 4 , Figure 5 , Figure 6 As shown, the active disk 5 includes a magnet bracket 52 fixedly connected to the motor shaft 71 and an active magnet 51 fixed above the magnet bracket 52. The heat dissipation fan 53 is formed on the bottom wall of the magnet bracket 52.

[0041] By including the magnet bracket 52 fixedly connected to the motor shaft 71 and the active magnet 51 fixed above the magnet bracket 52, and the heat dissipation fan 53 formed on the bottom wall of the magnet bracket 52, the magnet bracket 52 can be fixedly connected to the motor shaft 71 while also forming the heat dissipation fan 53. This dual-purpose design eliminates the need for a separate structural component to form the heat dissipation fan 53, which helps to simplify the overall structure of the machine and reduce the space occupied by the active disk 5.

[0042] As a preferred embodiment of this application, such as Figure 3 As shown, the host 6 includes a housing 62 that houses the motor 7. The top of the housing 62 is provided with a clearance opening for the motor shaft 71 to extend out. A current passage 621 is provided between the clearance opening and the motor shaft 71.

[0043] By providing a flow gap 621 between the clearance port and the motor shaft 71, the airflow can enter the host 6 or flow out from the host 6 through the flow gap 621 when the cooling fan 53 rotates with the active disk 5. This increases the flow rate and speed of the airflow near the active disk 5, thereby increasing the airflow near the active disk 5 per unit time. This further enhances the heat dissipation effect on the active disk 5, reduces its temperature rise, and also drives the airflow inside the host 6, thereby dissipating heat from the various components inside the host 6. This effectively prevents the equipment performance from degrading due to high temperature, ensuring the long-term efficient operation of the entire machine. The cooling fan 53 achieves a dual heat dissipation effect for both the active disk 5 and the various components inside the host 6, improving the overall heat dissipation efficiency of the equipment.

[0044] It should be noted that this application does not specifically limit the width of the flow gap 621. As a preferred embodiment of this application, the width L of the flow gap 621 satisfies: 5mm≤L≤15mm.

[0045] By setting the width L of the overcurrent gap 621 to satisfy: 5mm≤L≤15mm, the problem of airflow obstruction due to the width of the overcurrent gap 621 being too small is avoided, which would result in poor airflow and poor heat dissipation of the active disk 5. At the same time, the problem of the overcurrent gap 621 being too large is also avoided, which would result in an excessive gap between the motor shaft 71 and the clearance port, allowing external dust and impurities to easily enter the host 6, affecting the stability and service life of the equipment.

[0046] In a preferred embodiment of this application, the heat dissipation fan 53 is a centrifugal fan, and the bending direction of the heat dissipation fan 53 is the same as the rotation direction of the active disk.

[0047] By setting the heat dissipation fan 53 as a centrifugal fan, and the bending direction of the heat dissipation fan 53 is the same as the rotation direction of the active disk, the heat dissipation fan 53 can guide the airflow from bottom to top when it rotates with the active disk. This allows the airflow inside the host 6 to be driven by the heat dissipation fan 53, thereby achieving heat dissipation of various components inside the host 6, ensuring that the whole machine still maintains high efficiency in high-temperature environments, and further improving heat dissipation efficiency.

[0048] In a preferred embodiment of this application, the airflow driven by the heat dissipation fan 53 flows through the active disk 5 and the cup bottom cover 2, and the active disk 5 is located upstream of the airflow path relative to the cup bottom cover 2.

[0049] By directing the airflow driven by the cooling fan 53 to flow through the active disk 5 and the cup bottom cover 2, the airflow not only effectively dissipates heat from the active disk 5 but also carries away the heat accumulated in the cup bottom cover 2. This helps to further improve the heat dissipation effect of the entire bottom of the cup body 1 and the active disk 5, and further avoids the situation where the magnetic attraction between the active disk 5 and the driven disk 4 weakens due to excessive heat, ensuring the stability of the magnetic attraction between the two and ensuring the stability of food processing in the food processor. At the same time, the active disk 5 is located upstream of the cup bottom cover 2 in the airflow path, so that the airflow first dissipates heat from the active disk 5 and then from the cup bottom cover 2. This ensures that the temperature difference between the cold air and the active disk 5 is maintained, thereby improving the heat dissipation efficiency of the active disk 5. This avoids the situation where the airflow passes through the cup bottom cover 2 first and then the active disk 5, resulting in a significant temperature rise after passing through the cup bottom cover 2 and a small temperature difference with the active disk 5, thus reducing the heat dissipation effect of the active disk 5.

[0050] In a preferred embodiment of this application, the host 6 includes a housing 62 that houses the motor 7. The housing 62 is provided with a vent, through which airflow driven by the heat dissipation fan 53 is drawn in or discharged.

[0051] By providing ventilation openings in the outer casing 62, the airflow driven by the cooling fan 53 is drawn in or expelled through the ventilation openings, effectively preventing the formation of localized high temperatures due to the closed space near the active disk 5 causing the outside air to be unable to circulate. This achieves convection between the internal airflow and the external cool air, further improving the heat dissipation effect on the active disk 5. At the same time, while cooling the active disk 5, it can also drive the airflow inside the host 6, thereby achieving heat dissipation for various components inside the host 6. This ensures that the entire machine maintains efficient operation even in high-temperature environments, extends the service life of the equipment, and improves the user experience.

[0052] Furthermore, the motor 7 is located on the airflow path driven by the cooling fan blade 53.

[0053] By placing the motor 7 in the airflow path driven by the cooling fan 53, the motor 7 can be directly cooled by the airflow during operation, effectively reducing the temperature of the motor 7 and preventing performance degradation or damage caused by overheating of the motor 7, thus further ensuring the stable operation and long-term durability of the food processing machine.

[0054] Furthermore, the host 6 is also equipped with an air guide cover that covers the outside of the motor 7, with one end of the air guide cover connected to the ventilation port and the other end connected to the bottom of the active disk 5.

[0055] By providing an air guide shroud inside the main unit 6 that covers the outside of the motor 7, with one end of the air guide shroud connected to the ventilation port and the other end connected to the bottom of the active disk 5, the airflow driven by the heat dissipation fan 53 can be guided and concentrated by the air guide shroud to directly act on the motor 7 and the active disk 5, forming a directional cooling path, effectively improving the heat dissipation efficiency of the motor 7 and the disk, ensuring that the equipment maintains stable performance under high load, and extending its service life.

[0056] It should be noted that this application does not specifically limit the relative positional relationship between the motor 7 and the active disk 5 in the airflow path. As a preferred embodiment of this application, the motor 7 is located upstream of the active disk 5 in the airflow path, that is, the vent is the air inlet at this time.

[0057] By setting the motor 7 upstream of the active disk 5 in the airflow path, the airflow driven by the cooling fan 53 can pass through the motor 7 first and then through the active disk 5. This restricts the airflow to pass through a lower temperature area before cooling the higher temperature active disk 5, ensuring cooling efficiency. It also avoids the situation where the airflow passes through the active disk 5 first and then through the motor 7, resulting in a higher airflow temperature when passing through the active disk 5 and being carried to the motor 7, causing the motor 7 to have a lower cooling effect or even a further temperature rise.

[0058] As a preferred embodiment of this application, such as Figure 2 As shown, the main unit 6 has a mounting platform on top, and the cup body 1 is mounted on the mounting platform. The mounting platform has an annular rib 61 that extends upward and is positioned and matched with the cup body 1. The annular rib 61 has a connecting channel that connects the inner side of the annular rib 61 with the outside.

[0059] By providing an annular rib 61 that extends upward and is positioned to match the cup body 1 on the mounting platform, the host 6 is stably positioned on the cup body 1, ensuring the stability of the connection between the cup body 1 and the host 6, preventing the cup body 1 from falling off due to vibration or improper operation, and improving safety. At the same time, the annular rib 61 is provided with a communication channel connecting the inside of the annular rib 61 to the outside, so that the inside of the annular rib can be connected to the outside through the communication channel. This ensures that when the heat dissipation fan 53 drives the air flow, the air inside the annular rib 61 can achieve convection with the outside cold air, effectively reducing the temperature inside the annular rib 61, and further improving the heat dissipation effect on the active disk 5.

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.
