Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] Traditional food processors typically use a motor shaft that passes directly through the bottom wall of the mixing jar and connects to the mixing blades, enabling the blades to rotate and pulverize the food. Usually, the bottom wall of the mixing jar has some space for installation, excluding the shaft hole through which the shaft passes. Heating elements and thermal protection components are installed on the bottom wall of the mixing jar. These thermal protection components, such as fuses, provide overheat protection to prevent overheating, ensuring safe operation, preventing overflow and scorching, and mitigating the risk of dry burning.

[0003] With continuous research by researchers on food processing machines, an improved food processing machine has emerged: a motor drives a drive disk to rotate, and a mixing blade assembly is installed inside the mixing cup. The mixing blade assembly includes a blade holder with a drive disk and mixing blades mounted above the blade holder. The drive disk drives the drive disk to rotate in the air, and the drive disk drives the mixing blades to rotate, thus achieving pulverization. This avoids perforation of the bottom wall of the mixing cup.

[0004] In this type of machine, if the heating element and thermal protection element are fixed to the bottom wall of the mixing cup using traditional assembly methods, the limited space at the bottom of the mixing cup necessitates reducing the outer diameter of the drive disk to avoid obstructing the thermal protection element and heating element. This results in a small magnetic field coverage area for the drive disk, low magnetic flux exchange efficiency between the drive disk and the transmission disk, weak torque transmission capability, and low pulverization efficiency. Alternatively, the outer diameter of the mixing cup needs to be increased, leading to a larger mixing cup volume and inconvenience in use.

[0005] Based on this, the applicant wants to develop a new installation method that can reasonably assemble thermal protection components and heating tubes with the stirring cup, while ensuring efficient transmission between the drive disk and the transmission disk. Utility Model Content

[0006] This utility model provides a food processing machine, and a new assembly method for a magnetically driven food processing machine, which solves the technical problem of how to ensure magnetic transmission efficiency without reducing the installation space of the electromagnetic drive device while achieving reasonable installation of the thermal protection structure.

[0007] The technical solution adopted in this utility model is as follows:

[0008] This utility model provides a food processing machine, including a main unit, a mixing cup mounted on the main unit, and a blade assembly detachably mounted inside the mixing cup. The blade assembly includes a blade holder, a transmission disk mounted inside the blade holder, a mixing blade located above the blade holder, and a transmission shaft connecting the transmission disk and the mixing blade. The main unit is provided with an electromagnetic drive device for driving the transmission disk. The mixing cup includes a cup body and a cup holder sleeved at the bottom of the cup body. The cup holder has a transmission cavity with an opening at the lower end. The electromagnetic drive device extends into the transmission cavity. The transmission disk is located above the transmission cavity. The food processing machine also includes a heating tube, a temperature controller, and a fuse. The heating tube is fixed to the side wall of the cup body, and the temperature controller and the fuse are fixed to the bottom wall of the cup body and arranged at intervals around the transmission cavity.

[0009] The food processing machine provided by this utility model features a transmission cavity in the cup holder. When the stirring cup is installed on the main unit, the electromagnetic drive device extends into the transmission cavity, and the transmission disk is located above the transmission cavity. This results in a closer distance between the electromagnetic drive device and the transmission disk, ensuring a stronger magnetic attraction between them and improving the magnetic transmission efficiency. Furthermore, fixing the heating element to the side wall of the cup body rather than the bottom wall allows for a larger space on the bottom wall to install the thermostat and fuse. Simultaneously, the thermostat and fuse are fixed to the bottom wall of the cup body and spaced around the transmission cavity, resulting in a compact structure below the cup body. This fully utilizes the radial space of the cup body, and without increasing the radial dimensions of the cup body and ensuring the magnetic attraction between the electromagnetic drive device and the transmission disk, the thermostat and fuse are rationally installed to form dual overheat protection. The thermostat provides first-level protection by quickly sensing temperature changes and cutting off the motor power supply circuit when the preset temperature is reached, effectively preventing overflow and scorching. The fuse provides second-level protection by cutting off power if the thermostat fails, preventing dry burning and fire, thus ensuring higher safety.

[0010] In addition, fixing the heating tube to the side wall of the cup body rather than the bottom wall can reduce the obstruction of heat by the blade holder, which is conducive to the full utilization of the heat from the heating tube by the slurry in the cup body, thus achieving efficient slurry making.

[0011] In a preferred embodiment, the stirring cup further includes an external magnetic component disposed between the cup body and the cup base, and the blade holder is further provided with an internal magnetic component that magnetically engages with the external magnetic component. The external magnetic component, the temperature controller, and the fuse are arranged at intervals around the transmission cavity.

[0012] By incorporating external and internal magnetic components, the magnetic attraction between them ensures the knife assembly is stably and reliably installed within the cup. This eliminates the risk of the knife assembly flying out or falling off, whether during operation or user handling, further guaranteeing the safety and reliability of the food processing machine. The external magnetic component, the temperature controller, and the fuse are arranged at intervals around the transmission cavity, maximizing the use of the space around the cavity and achieving a compact structure and miniaturized cup.

[0013] In a preferred embodiment, the bottom of the cup body is provided with a heating plate and a heat-conducting plate sleeved on the outside of the heating plate. The heating tube is fixed to the outer wall of the heat-conducting plate. The bottom wall of the heat-conducting plate is provided with a mounting part for installing the thermostat and the fuse and a hollow hole corresponding to the transmission cavity. The external magnetic component is located in the hollow hole to be close to the bottom wall of the heating plate.

[0014] By setting up a heat-conducting plate, the heat from the heating tube is evenly conducted, resulting in uniform heat distribution on the heating plate and ensuring even heating of the slurry. This prevents localized high-temperature scorching or low-temperature scrambling. The bottom wall of the heat-conducting plate has a mounting part for the temperature controller and the fuse. The uniform heat transfer effect of the heat-conducting plate makes the temperature sensing of the temperature controller and the fuse more accurate. Simultaneously, by setting a perforation in the heat-conducting plate, the external magnetic component is located within the perforation to be close to the bottom wall of the heating plate. This ensures accurate detection by the temperature controller and the fuse, while also ensuring stronger magnetic attraction between the external and internal magnetic components, achieving reliable positioning of the blade assembly and the cup body.

[0015] In a preferred embodiment, the stirring cup further includes a lever that pushes the outer magnetic component away from the inner magnetic component, and the cup seat is provided with a radially extending guide groove, along which the outer magnetic component moves radially.

[0016] By using a joystick, the outer magnetic component is moved away from the inner magnetic component. When the user needs to remove the knife assembly, the joystick is used to move the outer magnetic component away from the inner magnetic component, thereby reducing or weakening the magnetic attraction between them. This reduces the resistance encountered by the user during knife assembly removal, making it easier to remove the knife assembly. Simultaneously, by providing a radially extending guide groove, the movement trajectory of the outer magnetic component will not interfere with the temperature controller and fuse, ensuring that the outer magnetic component has a sufficient magnetic field area along the circumference, providing a strong attraction force to the inner magnetic component and reliably positioning the knife assembly against the cup.

[0017] In a preferred embodiment, the heating tube is spirally wound around the side wall of the cup body, and the thermostat or the fuse is located between the transmission cavity and one end of the heating tube in the horizontal direction.

[0018] In a preferred embodiment, the heating tube extends circumferentially along the side wall of the cup body and forms an opening between the two ends of the heating tube, with the thermostat and the fuse disposed close to the opening.

[0019] By placing the thermostat or the fuse between the transmission cavity and one end of the heating tube; or by placing the thermostat and the fuse near the opening between the two ends of the heating tube, the thermostat and the fuse can be placed close to the cold end of the heating tube and away from the heating area of ​​the heating tube, thereby avoiding local high temperature radiation to the thermostat and the fuse, which could lead to inaccurate temperature sensing.

[0020] In a preferred embodiment, the bottom wall of the cup holder is provided with a clearance hole and a ring rib extending around the clearance hole and toward the bottom wall of the cup body. The ring rib abuts against the bottom wall of the cup body to form a transmission cavity with the bottom wall of the cup body, and the electromagnetic drive device is close to the bottom wall of the cup body.

[0021] By creating clearance holes in the bottom wall of the cup holder, a barrier between the electromagnetic drive device and the transmission disk is eliminated, allowing the electromagnetic drive device to move closer to the transmission disk, shortening the transmission distance and increasing transmission efficiency. Simultaneously, the ring ribs surrounding the clearance holes abut against the bottom wall of the cup body, resulting in a stronger seal between the cup holder and the bottom wall, achieving a waterproof effect.

[0022] In a preferred embodiment, the cup body includes a limiting wall surrounding the outer periphery of the blade holder and a heating wall connected to the top of the limiting wall, the heating wall extending obliquely from bottom to top, and the heating tube fixed to the heating wall and located above the blade holder.

[0023] By setting up a limiting wall and a heating wall, the limiting wall achieves radial limiting of the blade holder, allowing the blade assembly to be stably installed in the mixing cup. The heating tube is fixed to the heating wall and offset above the blade holder, meaning it heats the material inside the cup directly through the heating wall, preventing the heat from the heating tube from being absorbed or blocked by the blade holder, thus improving heating efficiency. Simultaneously, by extending the heating wall at an upward angle, the grinding space is expanded, and the inclined heating wall guides the grinding material to circulate upwards, improving the grinding effect. Furthermore, users can install the blade assembly vertically to prevent interference and achieve flexible assembly and disassembly of the blade assembly.

[0024] In a preferred embodiment, a temperature sensor is also fixed on the heating wall, and the temperature sensor is located above the knife holder.

[0025] A temperature sensor is also fixed on the heating wall, which can be located above the tool holder. That is, the temperature sensor is misaligned above the transmission disk inside the tool holder. At the same time, the heating wall extends outward from bottom to top compared to extending vertically upward. When the temperature sensor is fixed on the heating wall, it is further away from the tool holder radially, and even misaligned radially on the outer periphery of the transmission disk. Therefore, the temperature sensor is not only not affected by the magnetic eddy currents between the transmission disk and the electromagnetic drive device, but also avoids being directly affected by the magnetic field on the outer periphery of the transmission disk, thereby improving the detection accuracy of the temperature sensor.

[0026] In a preferred embodiment, the cup body includes a cup body with an open lower end and a heating plate encapsulated at the lower end of the cup body. The heating plate is installed in the cup holder and pressed against the lower end of the cup body by the cup holder. The limiting wall and the heating wall are disposed on the heating plate.

[0027] By utilizing the heating plate for efficient heat transfer and taking advantage of the cup body's expansion function, the cup structure is made complete. Limiting walls and heating walls are located on the heating plate. When installing the thermostat and fuse, they can be first fixed and assembled with the heating plate, and then assembled with the cup body along with the heating plate, achieving modular assembly and higher assembly efficiency.

[0042] like Figure 1 , 2 As shown, in one embodiment of the present invention, a food processing machine is provided, including a main unit 10, a mixing cup 20 mounted on the main unit 10, and a blade assembly 30 detachably mounted in the mixing cup 20. The blade assembly 30 includes a blade holder 31, a transmission disk 32 mounted in the blade holder 31, a mixing blade 33 located above the blade holder 31, and a transmission shaft 34 connecting the transmission disk 32 and the mixing blade 33. The main unit 10 is provided with an electromagnetic drive device 11 for driving the transmission disk 32. The mixing cup 20 includes a cup body 21 and a cup holder 23 sleeved on the bottom of the cup body 21. The cup holder 23 is provided with a transmission cavity 231 with an opening at the lower end. The electromagnetic drive device 11 extends into the transmission cavity 231, and the transmission disk 32 is located above the transmission cavity 231.

[0043] like Figure 2 , Figure 3 As shown, the food processing machine also includes a heating element 40, a temperature controller 50, and a fuse 60. The heating element 40 is fixed to the side wall of the cup body 21, and the temperature controller 50 and fuse 60 are fixed to the bottom wall of the cup body 21 and arranged at intervals around the transmission cavity 231. Optionally, the bottom wall of the cup holder 23 is provided with a clearance hole 232 and a ring rib 233 extending from the clearance hole 232 to the bottom wall of the cup body 21. The ring rib 233 abuts against the bottom wall of the cup body 21 to form the transmission cavity 231 with the bottom wall of the cup body 21, and the electromagnetic drive device 11 is close to the bottom wall of the cup body 21.

[0044] The food processing machine provided by this utility model has a transmission cavity 231 set in the cup holder 23. When the stirring cup 20 is installed on the main unit 10, the electromagnetic drive device 11 extends into the transmission cavity 231, and the transmission disk 32 is located above the transmission cavity 231. This means that the electromagnetic drive device 11 and the transmission disk 32 are closer together, ensuring a stronger magnetic attraction between them, thereby improving the magnetic transmission efficiency between the electromagnetic drive device 11 and the transmission disk 32. Furthermore, fixing the heating element 40 to the side wall of the cup body 21 rather than the bottom wall of the cup body 21 allows for a larger space on the bottom wall of the cup body 21 to install the thermostat 50 and the fuse 60. Simultaneously, the thermostat 50 and the fuse 60 are fixed to the bottom wall of the cup body 21 and arranged at intervals around the transmission cavity 231, resulting in a compact structure below the cup body 21. This fully utilizes the radial space of the cup body 21, and without increasing the radial dimensions of the cup body 21 and ensuring the magnetic attraction between the electromagnetic drive device 11 and the transmission disk 32, the thermostat 50 and the fuse 60 form a dual overheat protection system. The thermostat 50 provides the first level of protection by quickly sensing temperature changes and cutting off the power supply circuit to the motor 12 when the preset temperature is reached, effectively preventing overflow and scorching. The fuse 60 provides the second level of protection by cutting off power in case the thermostat 50 fails, preventing dry burning and fire, thus enhancing safety. In addition, the heating tube 40 is fixed to the side wall of the cup body 21 rather than the bottom wall of the cup body 21, which can reduce the obstruction of heat by the knife holder 31, and help the slurry in the cup body 21 to make full use of the heat of the heating tube 40 to achieve efficient slurry making.

[0045] By providing a clearance hole 232 on the bottom wall of the cup holder 23, the barrier between the electromagnetic drive device 11 and the transmission disk 32 is eliminated, allowing the electromagnetic drive device 11 to move closer to the transmission disk 32, shortening the transmission distance and increasing transmission efficiency. Simultaneously, because the annular rib 233 surrounding the clearance hole 232 abuts against the bottom wall of the cup body 21, the sealing between the cup holder 23 and the bottom wall of the cup body 21 is strengthened, achieving a waterproof effect for the cup holder 23.

[0046] Of course, in another embodiment, the bottom wall of the cup holder 23 arches upward to form a transmission cavity 231.

[0047] like Figure 4 As shown, in a preferred embodiment, the stirring cup 20 further includes an external magnetic element 80 disposed between the cup body 21 and the cup base 23, and the blade holder 31 is further provided with an internal magnetic element 35 that magnetically engages with the external magnetic element 80. Figure 3 As shown, the external magnetic component 80, the temperature controller 50, and the fuse 60 are arranged at intervals around the transmission cavity 231.

[0048] By incorporating an external magnetic component 80 and an internal magnetic component 35, the magnetic attraction between them ensures that the blade assembly 30 can be stably and reliably installed inside the cup body 21. Whether during operation or when the user is operating the cup body 21, there is no risk of the blade assembly 30 flying out or falling off, further guaranteeing the safety and reliability of the food processor. The external magnetic component 80, temperature controller 50, and fuse 60 are arranged at intervals around the transmission cavity 231, fully utilizing the space around the transmission cavity 231 to achieve a compact structure and a miniaturized cup body 21.

[0049] like Figure 5 , 6 As shown, in a preferred embodiment, the bottom of the cup body 21 is provided with a heating plate assembly, which includes a heating plate 22 and a heat-conducting plate 24 sleeved on the outside of the heating plate 22. The heating tube 40 is fixed to the outer wall of the heat-conducting plate 24. The bottom wall of the heat-conducting plate 24 is provided with a mounting part 241 for mounting a thermostat 50 and a fuse 60 and a hollow hole 242 corresponding to the transmission cavity 231. The external magnetic component 80 is located in the hollow hole 242 to be close to the bottom wall of the heating plate 22.

[0050] By setting up the heat-conducting plate 24, the heat from the heating tube 40 is evenly conducted, thereby ensuring uniform heat distribution on the heating plate 22 and achieving uniform heating of the slurry, preventing localized high-temperature scorching or low-temperature scrambling. The bottom wall of the heat-conducting plate 24 has a mounting part 241 for installing the temperature controller 50 and the fuse 60. The uniform heat transfer effect of the heat-conducting plate 24 makes the temperature sensing of the temperature controller 50 and the fuse 60 more accurate. Simultaneously, by setting a perforation 242 in the heat-conducting plate 24, the outer magnetic component 80 is located within the perforation 242 to be close to the bottom wall of the heating plate 22. This ensures accurate detection by the temperature controller 50 and the fuse 60, while also ensuring stronger magnetic attraction between the outer magnetic component 80 and the inner magnetic component 35, achieving reliable positioning of the blade assembly 30 and the cup body 21.

[0051] In another embodiment of this invention, the external magnetic component is fixedly disposed in the cup holder.

[0052] In another preferred embodiment, the outer magnetic element is movably disposed in the cup holder. Specifically, the stirring cup 20 also includes a lever 81, which pushes the outer magnetic element 80 away from the inner magnetic element 35, and the cup holder 23 is provided with a radially extending guide groove, along which the outer magnetic element 80 moves radially. Specifically, the outer magnetic element 80 moves along the guide groove between positions near and away from the center of the cup holder 23.

[0053] By setting up a control lever 81, the control lever 81 pushes the outer magnetic component 80 away from the inner magnetic component 35. When the user needs to remove the knife assembly 30, the control lever 81 is used to move the outer magnetic component 80 away from the inner magnetic component 35, thereby reducing or weakening the magnetic attraction between the outer magnetic component 80 and the inner magnetic component 35. This reduces the resistance encountered by the user during the removal of the knife assembly 30, making it easier to remove the knife assembly 30. At the same time, by setting a guide groove extending radially, the movement trajectory of the outer magnetic component 80 will not interfere with the temperature controller 50 and the fuse 60. This ensures that the outer magnetic component 80 has sufficient length and magnetic field area in the circumferential direction, resulting in a strong attraction force on the inner magnetic component 35, and achieving reliable positioning of the knife assembly 30 and the cup body 21.

[0054] This utility model does not limit the linkage method between the control lever 81 and the external magnetic component 80, nor the installation method of the control lever:

[0055] In one specific implementation example, the control lever 81 is radially inserted into the cup seat 23 and moves radially along the cup seat 23. The control lever 81 is provided with a pushing surface, and the outer magnetic component 80 is provided with a sliding surface that cooperates with the pushing surface. The pushing surface and the moving direction of the control lever 81 have an angle.

[0056] The control lever 81 is radially inserted into the cup holder 23 and moves radially along the cup holder 23. The control lever 81 can extend laterally from the cup holder 23 and be exposed to the user's field of vision, making the operation of the control lever 81 more intuitive and convenient. When the control lever 81 is pushed, the pushing surface of the control lever 81 and the sliding surface of the outer magnetic component 80 cooperate, causing the outer magnetic component to move smoothly away from the inner magnetic component 35, so as to easily remove the knife assembly 30.

[0057] In another specific embodiment, the joystick 81 is axially inserted into the cup holder 23 and moves along the cup holder 23. The joystick 81 is provided with a driving ramp, and the external magnetic component 80 is provided with a passive ramp that cooperates with the driving ramp. The driving ramp extends obliquely along the moving direction of the joystick 81. More preferably, the main unit 10 is provided with a clearance opening that avoids the joystick 81.

[0058] By inserting the control lever 81 axially along the cup holder 23 and moving it axially along the cup holder 23, when the mixing cup 20 is placed on any table surface, the control lever 81 can be automatically moved axially by the weight of the mixing cup 20 itself and the support of the table surface, eliminating the need for manual operation by the user and automating the operation of the external magnetic component 80. This also makes the removal and removal of the blade assembly 30 easier. When the control lever 81 contacts the table surface, the driving inclined surface of the control lever 81 engages with the passive inclined surface of the external magnetic component 80, causing the external magnetic component to move smoothly away from the internal magnetic component 35, making it easy to remove the blade assembly 30.

[0059] Furthermore, this invention does not limit the position of the heating element, thermostat, and fuse. Preferably, the thermostat and fuse are positioned near the cold end of the heating element. For example, the heating element 40 is spirally wound around the side wall of the cup body 21 at least once, and the thermostat 50 or fuse 60 is located between the transmission cavity 231 and one end of the heating element 40 in the horizontal direction. Alternatively, the heating element 40 extends circumferentially along the side wall of the cup body 21, forming an opening between the two ends of the heating element 40, with the thermostat 50 and fuse 60 positioned near the opening.

[0060] By placing the thermostat 50 or the fuse 60 between the transmission cavity 231 and one end of the heating tube 40; or by placing the thermostat 50 and the fuse 60 near the opening between the two ends of the heating tube 40, the thermostat 50 and the fuse 60 can be placed close to the cold end of the heating tube 40 and away from the heating area of ​​the heating tube 40, thereby avoiding local high temperature radiation to the thermostat 50 and the fuse 60, which would lead to inaccurate temperature sensing.

[0061] like Figure 1-6 As shown, this utility model does not limit the structure of the stirring cup. In a preferred embodiment, the cup body 21 includes a limiting wall 212 surrounding the outer periphery of the blade holder 31 and a heating wall 213 connected to the top of the limiting wall 212. The heating wall 213 extends obliquely from bottom to top, and the heating tube 40 is fixed to the heating wall 213 and located above the blade holder 31. More preferably, a temperature sensor 70 is also fixed on the heating wall 213, and the temperature sensor 70 is located above the blade holder 31.

[0062] In this embodiment, the cup body 21 includes a cup body 211 with an open lower end and a heating plate 22 encapsulated at the lower end of the cup body 211. The heating plate 22 is installed in the cup holder 23 and pressed against the lower end of the cup body 211 by the cup holder 23. A limiting wall 212 and a heating wall 213 are disposed on the heating plate 22.

[0063] By setting a limiting wall 212 and a heating wall 213, the limiting wall 212 is used to radially limit the blade holder 31, allowing the blade assembly 30 to be stably installed in the mixing cup 20. The heating tube 40 is fixed to the heating wall 213 and offset above the blade holder 31, meaning that the material inside the cup 21 is heated directly through the heating wall 213, preventing the heat from the heating tube 40 from being absorbed or blocked by the blade holder 31, thus improving heating efficiency. At the same time, by extending the heating wall 213 at an angle from bottom to top, the grinding space is expanded, and the inclined heating wall 213 guides the grinding material to circulate upwards, improving the grinding effect. Moreover, the user can install the blade assembly 30 vertically to prevent interference and achieve flexible assembly and disassembly of the blade assembly. A temperature sensor 70 is also fixed on the heating wall 213, which can be located above the tool holder 31. That is, the temperature sensor 70 is misaligned above the transmission disk 32 inside the tool holder 31. At the same time, the heating wall 213 extends outward from bottom to top compared to extending vertically upward. When the temperature sensor 70 is fixed on the heating wall 213, it is further away from the tool holder 31 in the radial direction, and even misaligned in the radial direction on the outer periphery of the transmission disk 32. Therefore, the temperature sensor 70 is not only not affected by the magnetic eddy current between the transmission disk 32 and the electromagnetic drive device 11, but also avoids being directly affected by the magnetic field on the outer periphery of the transmission disk 32, thereby improving the detection accuracy of the temperature sensor 70.

[0064] By setting up a heating plate 22 for efficient heat transfer, and utilizing the expansion function of the cup body 211, the structural integrity of the cup body 21 is achieved. The limiting wall 212 and heating wall 213 are located on the heating plate 22. When installing the temperature controller 50 and fuse 60, they can be first fixedly assembled with the heating plate 22, and then assembled with the cup body 211 along with the heating plate 22, achieving modular assembly and higher assembly efficiency.
