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. When the mixing jar includes a heating plate, the heating plate forms the bottom wall of the mixing jar. To monitor temperature during food processing, the mixing jar is usually equipped with a temperature sensor. In these types of machines, there are two main ways to set up the temperature sensor:

[0003] One method involves placing the temperature sensor against the bottom wall of the mixing cup to indirectly detect the temperature of the slurry by detecting the temperature of the heating plate; the other method involves inserting the temperature sensor directly through the bottom wall of the mixing cup, thus directly detecting the temperature of the slurry inside the mixing cup.

[0004] As researchers continue to study food processing machines, an improved food processing machine has been developed to avoid the bottom wall of the mixing cup being perforated by the motor shaft. The machine uses a motor to drive 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.

[0005] For this type of machine, if the temperature sensor is inserted through the bottom wall of the mixing bowl, the magnetic field formed around the drive disk inside the blade holder, especially the magnetic eddy currents formed between the drive disk and the drive disk below it, and the strong magnetic field formed on the outer periphery of the drive disk during its rotation, will affect the temperature sensor's detection, regardless of whether the temperature sensor is in contact with or through the bottom wall of the heating plate, making it impossible to achieve accurate temperature detection.

[0006] In addition, since the blade holder is installed on the bottom wall of the mixing cup, the researchers need to consider the avoidance of the blade holder and the temperature sensor. If the blade holder is designed to avoid the sensor, it will lead to a more complex design of the blade assembly and a more complex overall structure of the mixing cup. Utility Model Content

[0007] This utility model provides a food processing machine, a magnetically driven food processing machine, and a simple and reliable temperature sensor installation method, which solves the technical problem that the temperature sensor is inaccurate due to interference from the blade holder and the influence of the magnetic field around the transmission disk.

[0008] The technical solution adopted in this utility model is as follows:

[0009] 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 rotatably mounted inside the blade holder, a mixing blade located above the blade holder, and a transmission shaft passing through the blade holder to connect the transmission disk and the mixing blade. The main unit is provided with an electromagnetic drive device for driving the transmission disk remotely. The blade holder is mounted on the bottom wall of the mixing cup. The mixing cup includes a limiting wall surrounding the outer periphery of the blade holder and a heating wall connected above the limiting wall. A heating tube is fixed to the outer side of the heating wall, and the heating wall extends outward from bottom to top. The food processing machine also includes a temperature sensor, which is fixed to the heating wall and located above the blade holder.

[0010] The food processing machine provided by this utility model includes a mixing cup comprising a limiting wall surrounding the outer periphery of the blade holder and a heating wall connected above the limiting wall. The blade holder is mounted on the bottom wall of the mixing cup and radially limited by the limiting wall, ensuring reliable installation of the blade holder within the mixing cup. By installing a heating tube on the heating wall, which is connected above the limiting wall and extends outwards from bottom to top, the temperature sensor, when fixed to the heating wall, is positioned above the blade holder, i.e., misaligned above the drive disk within the blade holder. Furthermore, compared to a vertically upward extension, the outwardly extending heating wall causes the temperature sensor to be radially further away from the blade holder, even radially misaligned around the outer periphery of the drive disk. Therefore, whether the temperature sensor is abutting the outside of the heating wall or penetrates it, the temperature sensor is highly misaligned with the drive disk and radially away from it. This prevents the temperature sensor from being affected by the magnetic eddy currents between the drive disk and the electromagnetic drive device, and also avoids direct influence from the magnetic field around the drive disk, thereby improving the detection accuracy of the temperature sensor.

[0011] Of course, the outward tilt of the heating wall from bottom to top creates ample clearance between the temperature sensor and the blade assembly, allowing users to install the blade assembly vertically without interference. This enables flexible assembly and disassembly of the blade assembly without requiring any clearance design on the blade holder, resulting in a simple structure. Furthermore, since the heating element is fixed to the heating wall, it can also be positioned above the blade holder, directly heating the material in the mixing cup through the heating wall. This prevents the heat from being absorbed or blocked by the blade holder, improving heating efficiency.

[0012] In a preferred embodiment, the temperature sensor is disposed through the heating wall, and the temperature sensor does not coincide with the axial projection of the tool holder.

[0013] By embedding the temperature sensor through the heating wall, it directly contacts the slurry in the mixing cup, enabling more direct temperature sensing and detection of the slurry and further improving detection accuracy. Furthermore, the axial projection of the temperature sensor and the cutter holder does not coincide, avoiding interference between them during cutter assembly and disassembly. This facilitates quick assembly and disassembly of the cutter assembly, allowing users to install the cutter assembly vertically without needing to tilt it to avoid the temperature sensor, making operation convenient.

[0014] In a preferred embodiment, the heating tube is spirally wound around the heating wall, the heating tube includes a circumferential portion that surrounds the heating wall at least once and a terminal portion that is connected to the circumferential portion and extends above the circumferential portion, the temperature sensor being located above the circumferential portion and overlapping the height of the terminal portion.

[0015] By spiraling the heating tube around the heating wall, the heating wall is heated from all directions, thereby improving the heating efficiency of the slurry in the stirring cup. The temperature sensor is located above the spiral part and overlaps with the end part at the same height. The temperature sensor avoids the heating tube and shares the same height with the end part of the heating tube, making the installation more compact.

[0016] In a preferred embodiment, the heating tube extends circumferentially along the heating wall and forms an opening between its two ends, with the temperature sensor located in the opening.

[0017] By placing the temperature sensor in the opening, that is, near the two cold ends of the heating tube, the thermal radiation effect of the heating tube on the temperature sensor is reduced, thus avoiding affecting the lifespan and detection effect of the temperature sensor and improving detection accuracy.

[0018] In a preferred embodiment, the temperature sensor is located above the heating element.

[0019] By placing a temperature sensor above the heating element, the two are well misaligned in height. At the same time, the temperature sensor is further away from the transmission disk along the height direction, reducing the influence of the transmission disk's magnetic field and improving detection accuracy.

[0020] In a preferred embodiment, the outer side of the heating wall is wrapped with a heat-conducting layer, the heating tube is fixed outside the heat-conducting layer, the heat-conducting layer is provided with a clearance corresponding to the position of the temperature sensor, and the temperature sensor is located in the clearance to isolate it from the heat-conducting layer.

[0021] By setting a heat-conducting layer, the heating tube is fixed outside the heat-conducting layer. The heat-conducting layer evenly transfers the heat from the heating tube to the heating plate, achieving uniform heating and avoiding temperature concentration. By setting a clearance opening in the heat-conducting layer corresponding to the position of the temperature sensor, the temperature sensor is located in the clearance opening and isolated from the heat-conducting layer, thereby preventing the heat-conducting layer from transferring the heat from the heating tube to the temperature sensor. This prevents the temperature sensor from being damaged by heat or from inaccurate detection, extending the service life of the temperature sensor and improving detection accuracy.

[0022] In a preferred embodiment, the upper surface edge of the tool holder is provided with a gradually downward sloping portion, and the temperature sensor is above the lowest point of the sloping portion.

[0023] Because the tip of the mixing blade has a higher linear velocity than the root when rotating, the grinding is finer and the grinding effect is better. Therefore, the upper surface of the blade holder is tilted upward from the center to the edge, so that the material can fully contact the tip of the mixing blade and improve the grinding effect. Moreover, the material flows towards the edge of the blade holder and gets closer to the heating tube, realizing the efficient utilization of the heat of the heating tube and the high heating efficiency.

[0024] In a preferred embodiment, the stirring blade extends at least partially into the radially inner side of the heated wall.

[0025] By extending at least partially into the radially inner side of the heating wall, a concentrated grinding chamber is formed between the upper surface of the blade holder and the heating wall, achieving fine grinding of materials and improving grinding fineness. The heating wall extends outward at an angle from bottom to top, guiding the material in the concentrated grinding chamber to circulate upward, thereby achieving circulating grinding and improving grinding efficiency.

[0026] In a preferred embodiment, the sidewall of the tool holder is radially limited by the limiting wall and an exhaust channel is provided on the sidewall of the tool holder, and the top edge of the tool holder protrudes outward to form a shielding portion that covers the exhaust channel.

[0027] The venting channel design provides clearance between the side wall of the blade holder and the limiting wall of the mixing cup, preventing interference and collisions during blade assembly installation, thus facilitating installation. The blade holder's top edge protrudes outwards to form a shield above the venting channel. Even if residual water remains in the mixing cup, it will splash upwards through the venting channel when the user places the blade assembly, and will be blocked by the edge of the top wall, preventing further splashing onto the user's arm or outside the mixing cup, effectively solving the problem of residual water splashing. Furthermore, the mixing cup's inner cavity is divided into a lower chamber and an upper chamber by the blade holder. After the blade assembly is installed, the venting channel ensures pressure balance between the upper and lower chambers. This prevents excessive suction from the lower chamber when the user needs to remove the blade assembly, thus avoiding difficult disassembly and enabling easy removal of the blade assembly.

[0028] In a preferred embodiment, the stirring cup includes a cup body with an open lower end and a metal heating plate enclosed at the lower end of the glass cup body. The blade holder is mounted on the inner bottom wall of the heating plate. The side wall of the heating plate includes the limiting wall and the heating wall from bottom to top. The cup body is connected above the heating wall.

[0029] By setting a metal heating plate, the thermal conductivity is improved, so that the heat from the heating tube can be fully transferred to the slurry in the mixing cup, forming efficient heating. The side wall of the heating plate includes the limiting wall and the heating wall from bottom to top, so that the temperature sensor, heating plate and heating tube can be directly formed into a component during assembly, making the assembly modular and easier.

[0030] In a preferred embodiment, the stirring cup is a metal or glass cup with a bottom, and the side wall of the stirring cup includes, from bottom to top, the limiting wall, the heating wall, and an upwardly extending expansion wall.

[0031] The mixing cup uses a metal or glass body, and the one-piece body has a simple structure that does not require complicated assembly. At the same time, the side wall of the mixing cup includes the limiting wall, the heating wall and the upwardly extending expansion wall from bottom to top. The limiting wall is used to limit the tool holder, the heating wall is used to install the temperature sensor and heating tube, and the expansion wall can also ensure the processing capacity of a single processing. The structure is simple, complete and reliable. Attached Figure Description

[0047] like Figure 1-7 As shown, in one embodiment, this utility model provides a food processing machine, including a main unit 10, a mixing cup 20 mounted on the main unit 10, and a blade assembly 30 detachably mounted inside the mixing cup 20. The blade assembly 30 includes a blade holder 31, a transmission disk 32 rotatably mounted inside the blade holder 31, a mixing blade 33 located above the blade holder 31, and a transmission shaft 34 passing through the blade holder 31 to connect the transmission disk 32 and the mixing blade 33. The main unit 10 is provided with an electromagnetic drive device 11 for air-driven transmission disk 32. The blade holder 31 is mounted on the bottom wall of the mixing cup 20. Figure 2As shown, the mixing cup 20 includes a limiting wall 201 surrounding the outer periphery of the blade holder 31 and a heating wall 202 connected above the limiting wall 201. A heating tube 40 is fixed to the outer side of the heating wall 202 and the heating wall 202 extends outward from bottom to top. The food processor also includes a temperature sensor 50, which is fixed to the heating wall 202 and located above the blade holder 31.

[0048] In this embodiment, such as Figure 1 As shown, the electromagnetic drive device 11 includes a motor 12 and a drive disk 13 driven by the motor 12. The drive disk 13 is located below the transmission disk 32 and drives the transmission disk 32 to rotate.

[0049] like Figure 2 As shown, in a preferred embodiment, the stirring cup 20 includes a cup body 21 with an open lower end and a metal heating plate 22 enclosed at the lower end of the glass cup body 21. The knife holder 31 is installed on the inner bottom wall of the heating plate 22. The side wall of the heating plate 22 includes a limiting wall 201 and a heating wall 202 from bottom to top. The cup body 21 is connected above the heating wall 202.

[0050] By setting a metal heating plate 22, the thermal conductivity is improved, so that the heat from the heating tube 40 can be fully transferred to the slurry in the mixing cup 20, forming efficient heating. The side wall of the heating plate 22 includes a limiting wall 201 and a heating wall 202 from bottom to top, so that the temperature sensor 50, the heating plate 22 and the heating tube 40 can be directly integrated into a single component during assembly, making the assembly modular and easier.

[0051] The food processing machine provided by this utility model includes a mixing cup 20 comprising a limiting wall 201 surrounding the outer periphery of a blade holder 31 and a heating wall 202 connected above the limiting wall 201. The blade holder 31 is mounted on the bottom wall of the mixing cup 20 and radially limited by the limiting wall 201, ensuring reliable installation of the blade holder 31 within the mixing cup 20. By installing a heating tube 40 on the heating wall 202, and by connecting the heating wall 202 above the limiting wall 201 and extending outwards from bottom to top, the temperature sensor 50, when fixed to the heating wall 202, can be positioned above the blade holder 31, i.e., the temperature sensor 50 is misaligned above the transmission disk 32 within the blade holder 31. Furthermore, compared to extending vertically upwards, the outwards tilting of the heating wall 202 causes the temperature sensor 50 to be radially further away from the blade holder 31, even radially misaligned around the outer periphery of the transmission disk 32. Therefore, whether the temperature sensor 50 is abutting against the outside of the heating wall 202 or is installed through the heating wall 202, the temperature sensor 50 is highly misaligned with the transmission disk 32 and radially away from the transmission disk 32. This ensures that the temperature sensor 50 is not only unaffected by the magnetic eddy currents between the transmission disk 32 and the electromagnetic drive device 11, but also avoids being directly affected by the magnetic field around the transmission disk 32, thereby improving the detection accuracy of the temperature sensor 50.

[0052] The heating wall 202 slopes outwards from bottom to top, creating ample clearance between the temperature sensor 50 (which is installed through it) and the blade assembly 30. This allows users to install the blade assembly 30 vertically, preventing interference and enabling flexible assembly and disassembly of the blade assembly. Furthermore, no clearance design is required on the blade holder 31, resulting in a simple structure. Additionally, since the heating tube 40 is fixed to the heating wall 202, it can also be positioned above the blade holder 31, allowing direct heating of the material inside the mixing cup 20 through the heating wall 202. This prevents the heat from the heating tube 40 from being absorbed or blocked by the blade holder 31, improving heating efficiency.

[0053] It should be noted that the present invention is not limited to the above-described structure of the stirring cup. In another preferred embodiment, the stirring cup 20 is a metal or glass cup with a bottom, and the side wall of the stirring cup 20 includes a limiting wall 201, a heating wall 202, and an upwardly extending expansion wall from bottom to top. It can be understood that in this embodiment, the limiting wall 201, the heating wall 202, and the expansion wall constitute an integral cup body.

[0054] The mixing cup 20 adopts a metal cup body 21 or a glass cup body 21. The one-piece cup body 21 has a simple structure and does not require complicated assembly. Meanwhile, the side wall of the mixing cup 20 includes a limiting wall 201, a heating wall 202 and an upwardly extending expansion wall from bottom to top. The limiting wall 201 is used to limit the tool holder 31, the heating wall 202 is used to install the temperature sensor 50 and the heating tube 40, and the expansion wall can also ensure the processing capacity of a single processing. The structure is simple, complete and reliable.

[0055] Of course, the structure of the electromagnetic drive device is not limited to the one described above. In other embodiments, the electromagnetic drive device 11 includes a stator and a coil winding wound around the stator. The coil winding is energized to generate a magnetic field to drive the transmission disk 32 to rotate.

[0056] In addition, such as Figure 3 As shown, in a preferred embodiment, the temperature sensor 50 is disposed through the heating wall 202, and the axial projection of the temperature sensor 50 and the tool holder 31 does not coincide. Specifically, in conjunction with Figure 4 As shown, a mounting hole 203 is provided in the heating wall 202, and the temperature sensor 50 is sealed and installed in the mounting hole 203.

[0057] By embedding the temperature sensor 50 through the heating wall 202, the temperature sensor 50 directly contacts the slurry inside the mixing cup 20, enabling more direct temperature sensing and detection of the slurry and further improving detection accuracy. Furthermore, the axial projections of the temperature sensor 50 and the cutter holder 31 do not coincide, avoiding interference between the temperature sensor 50 and the cutter holder 31 during the assembly and disassembly of the cutter assembly 30. This facilitates quick assembly and disassembly of the cutter assembly, allowing users to install the cutter assembly 30 vertically without needing to tilt it to avoid the temperature sensor 50, making operation convenient.

[0058] Combination Figure 4 , 5 As shown in Figure 6, in a preferred embodiment, the outer side of the heating wall 202 is wrapped with a heat-conducting layer 23, the heating tube 40 is fixed outside the heat-conducting layer 23, the heat-conducting layer 23 is provided with a clearance opening 231 corresponding to the position of the temperature sensor 50, and the temperature sensor 50 is located in the clearance opening 231 to isolate it from the heat-conducting layer 23.

[0059] By setting a heat-conducting layer 23, the heating tube 40 is fixed outside the heat-conducting layer 23. The heat-conducting layer 23 evenly transfers the heat of the heating tube 40 to the heating plate 22, achieving uniform heating and avoiding temperature concentration. By setting a clearance opening 231 corresponding to the position of the temperature sensor 50 in the heat-conducting layer 23, the temperature sensor 50 is located in the clearance opening 231 and isolated from the heat-conducting layer 23, thereby preventing the heat-conducting layer 23 from transferring the heat of the heating tube 40 to the temperature sensor 50. This prevents the temperature sensor 50 from being damaged by heat or from inaccurate detection, and extends the service life of the temperature sensor 50 and improves the detection accuracy.

[0060] It should be noted that this invention does not limit the positional relationship between the temperature sensor and the heating element; for example, as... Figure 5 , 6 As shown, in a preferred embodiment, the heating tube 40 is spirally wrapped around the heating wall 202. The heating tube 40 includes a circumferential portion 41 that surrounds the heating wall 202 at least once and a terminal portion 42 that is connected to the circumferential portion 41 and extends above the circumferential portion 41. The temperature sensor 50 is located above the circumferential portion 41 and overlaps with the height of the terminal portion 42.

[0061] By spirally wrapping the heating tube 40 around the heating wall 202, the heating wall 202 is heated in all directions, thereby improving the heating efficiency of the slurry in the stirring cup 20. The temperature sensor 50 is located above the wrapping part 41 and overlaps with the end part 42 at the same height. The temperature sensor 50 avoids the heating tube 40 and shares the height with the end part 42 of the heating tube 40, making the installation more compact.

[0062] In other preferred embodiments, the heating tube 40 extends less than one full circle around the heating wall 202 and forms an opening between its two ends, in which the temperature sensor 50 is located.

[0063] By placing the temperature sensor 50 in the opening, that is, near the two cold ends of the heating tube 40, the thermal radiation effect of the heating tube 40 on the temperature sensor 50 is reduced, thus avoiding affecting the lifespan and detection effect of the temperature sensor 50 and improving detection accuracy.

[0064] In other preferred embodiments, the temperature sensor 50 is located above the entire heating tube 40.

[0065] The temperature sensor 50 is positioned above the heating tube 40, creating a good height misalignment between the two. At the same time, the temperature sensor 50 is further away from the transmission disk 32 along the height direction, reducing the influence of the magnetic field of the transmission disk 32 and improving the detection accuracy.

[0066] In a preferred embodiment, such as Figure 1 As shown, the upper surface edge of the tool holder 31 is provided with an inclined portion 311 that gradually slopes downward, and the temperature sensor 50 is higher than the lowest point of the inclined portion 311.

[0067] Because the tip of the stirring blade 33 has a greater linear velocity than the root when it rotates, the pulverization is finer and the pulverization effect is better. Therefore, the upper surface of the blade holder 31 is inclined upward from the center to the edge, so that the material can fully contact the tip of the stirring blade 33 and improve the pulverization effect. Moreover, the material flows towards the edge of the blade holder 31 and gets closer to the heating tube 40, so as to realize the efficient utilization of the heat of the heating tube 40 and the high heating efficiency.

[0068] In a preferred embodiment, the stirring blade 33 extends at least partially into the radially inner side of the heating wall 202.

[0069] By extending at least part of the stirring blade 33 into the radially inner side of the heating wall 202, a concentrated crushing chamber is formed between the upper surface of the blade holder 31 and the heating wall 202, thereby achieving fine crushing of materials and improving the fineness of the crushing. The heating wall 202 extends outward at an angle from bottom to top, guiding the material in the concentrated crushing chamber to circulate upward, thereby achieving circulating crushing and improving crushing efficiency.

[0070] In a preferred embodiment, such as Figure 7 As shown, the side wall of the tool holder 31 is radially limited by the limiting wall 201, and an exhaust channel 312 is provided on the side wall of the tool holder 31. The top edge of the tool holder 31 protrudes outward to form a blocking part 313 that blocks the exhaust channel.

[0071] The exhaust channel design provides clearance between the side wall of the blade holder 31 and the limiting wall 201 of the mixing cup 20, preventing interference and collisions during blade assembly 30 installation, thus facilitating installation. The blade holder 31's top edge protrudes outwards to form a shield above the exhaust channel. Even if residual water remains in the mixing cup 20, when the user places the blade assembly 30, the residual water splashes upwards through the exhaust channel and is then blocked by the edge of the top wall, preventing it from splashing further upwards onto the user's arm or outside the mixing cup 20, effectively solving the problem of residual water splashing. Furthermore, the blade holder 31 divides the inner cavity of the mixing cup 20 into a lower chamber and an upper chamber. After the blade assembly 30 is installed, the exhaust channel balances the air pressure in the upper and lower chambers. Therefore, when the user needs to remove the blade assembly 30, the lower chamber will not exert too much suction on the blade holder 31, preventing difficult disassembly and allowing for easy removal of the blade assembly 30.
