Abstract
Description
Technical Field
[0001] This application relates to the field of food processing, and more particularly to a heating plate assembly, a mixing cup assembly, and a food processor. Background Technology
[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of food processors mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors can include soy milk makers, blenders, or high-speed blenders—machines that pulverize and mix food. Existing food processors suffer from uneven heating of ingredients and a tendency to burn food. Utility Model Content
[0003] This application provides a heating plate assembly, a mixing cup assembly, and a food processor that heats ingredients evenly and prevents them from sticking to the bottom.
[0004] This application provides a heating plate assembly. The heating plate assembly includes a base, an insulating heat transfer layer, a heating layer, and an insulating heat insulation layer. The insulating heat transfer layer is disposed between the base and the heating layer, and the insulating heat insulation layer is disposed on the side of the heating layer away from the insulating heat transfer layer. The heating layer includes an insulating plate and a heating wire wound around the insulating plate. The ratio of the projected area of the heating wire on the insulating plate to the surface area of the insulating plate is greater than 30%. Because the heating wire is wound around the insulating plate, and the ratio of the projected area of the heating wire on the insulating plate to the surface area of the insulating plate is greater than 30%, the heating area is increased compared to traditional heating tubes where heat is concentrated in one ring. When the heating wire is energized, it heats the food in the mixing cup, resulting in more even heating, effectively preventing scorching, and providing a better user experience.
[0005] Furthermore, the heating plate assembly also includes two terminals and two insulating sleeves. Each of the two terminals passes through the insulating and heat-insulating layer and is connected to both ends of the heating wire. The two insulating sleeves are respectively fitted over the two terminals. Thus, the insulating sleeves provide insulation and heat insulation for the terminals.
[0006] Furthermore, the heating plate assembly also includes a fixing member. The chassis includes a plate body and surrounding ribs around the plate body. The fixing member is fixed to the surrounding ribs, confining the insulating heat transfer layer, the heating layer, and the insulating heat insulation layer between the plate body and the fixing member. This makes the assembly of the heating plate assembly convenient and reliable.
[0007] Furthermore, the heating plate assembly also includes a reinforcing insulation layer disposed on the side of the fixing member away from the insulating insulation layer. By providing a heating insulation layer, the heat generated by the heating layer is further reduced from being conducted away from the base, while allowing more heat to be conducted towards the base, resulting in higher heating efficiency for the food.
[0008] Furthermore, the insulating plate is ring-shaped, and the heating wire is wound radially and evenly distributed circumferentially on the insulating plate. This ensures more uniform heating of the ingredients in the mixing cup.
[0009] Furthermore, the insulating plate is uniformly provided with a plurality of slots on its inner and outer sides along the radial direction, and the heating wire is confined within the slots; and / or, the heating wire is uniformly distributed on the insulating plate circumferentially. By providing the slots, the heating wire can be confined, preventing displacement of the heating wire on the insulating plate during use, thereby ensuring that the heating wire is always uniformly wound on the insulating plate.
[0010] Furthermore, the insulating and heat-insulating layer includes an insulating layer adjacent to the heating layer and a heat-insulating layer adjacent to the insulating layer. Thus, the insulating layer provides insulation for the heating wire, and the heat-insulating layer provides heat insulation, reducing downward heat conduction.
[0011] Furthermore, the insulating layer is made of mica sheet, and its thickness ranges from 0.3 mm to 1 mm. This results in low cost and facilitates a reduction in the thickness of the heating element assembly. The heat insulation layer is made of mica sheet or fiberglass. This also results in low cost and good heat insulation performance.
[0012] Furthermore, the chassis is made of metal, and its thickness ranges from 0.3 mm to 2 mm. This results in good heat transfer. The insulating heat transfer layer is made of alumina or mica sheets, and its thickness ranges from 0.4 mm to 2.0 mm. This provides good heat transfer performance at a low cost.
[0013] Furthermore, the insulating plate is made of mica sheet, and the thickness of the insulating plate ranges from 0.3 mm to 1 mm. This allows the heating wire to be wound around the mica sheet, which helps the heating wire maintain good performance and has a longer service life.
[0014] Furthermore, the ratio of the projected area of the heating wire on the insulating plate to the surface area of the insulating plate is greater than 50%. This ensures both uniform heating and higher heating efficiency.
[0015] This application also provides a mixing cup assembly. The mixing cup assembly includes: a mixing cup; and a heating plate assembly as described above, disposed at the bottom of the mixing cup.
[0016] This application also provides a food processor. The food processor includes: a base; and a mixing cup assembly as described above, detachably mounted on the base. Attached Figure Description

[0025] Please see Figures 1 to 8 The food processor 100 can be used to make soy milk, rice paste, juice, etc. The food processor 100 includes a base 70, a blending cup assembly 60, and a cover 80. The blending cup assembly 60 is detachably mounted to the base 70.
[0026] The mixing cup assembly 60 includes a mixing cup 61, a heating plate assembly 62, and a cover 80. The heating plate assembly 62 is disposed at the bottom of the mixing cup 61, and the cover 80 covers the mixing cup 61. In the illustrated embodiment, the mixing cup assembly 60 also includes a motor 63 mounted at the bottom of the mixing cup 61. The motor 63 includes a motor shaft 64 passing through the heating plate assembly 62, and a blade assembly 65 is provided at the top of the motor shaft 64. In another embodiment, a motor is disposed within a base 70, and the blade assembly includes a rotating shaft passing through the heating plate assembly 62. The rotating shaft is connected to the motor shaft of the motor via a clutch structure. In the illustrated embodiment, the mixing cup 61 includes a cup body 611 and a cup holder 612. The heating plate assembly 62 is clamped and fixed by the cup body 611 and the cup holder 612, and the motor 63 is disposed within the cup holder 612.
[0027] The heating plate assembly 62 includes a base 10, an insulating heat transfer layer 20, a heating layer 30, and an insulating heat insulation layer 40. The insulating heat transfer layer 20 is disposed between the base 10 and the heating layer 30. The insulating heat insulation layer 40 is disposed on the side of the heating layer 30 away from the insulating heat transfer layer 20. The heating layer 30 includes an insulating plate 31 and heating wires 32 wound around the insulating plate 31. The ratio of the projected area of the heating wires 32 on the insulating plate 31 to the surface area of the insulating plate 31 is greater than 30%. Here, "projected area" includes the sum of the projected area of the heating wires 32 located on the upper side of the insulating plate 31 on the upper surface and the projected area of the heating wires 32 located on the lower side of the insulating plate 31 on the lower surface. Here, "surface area of the insulating plate 31" includes the sum of the upper surface area and the lower surface area of the insulating plate 31.
[0028] Because the heating wire 32 is wound around the insulating plate 31, and the ratio of the projected area of the heating wire 32 on the insulating plate 31 to the surface area of the insulating plate 31 is greater than 30%, the heating area is increased compared with the traditional heating tube where the heat is concentrated in one circle. After the heating wire 32 is energized, it heats the food in the mixing cup 61, making the food heat more evenly, effectively avoiding scorching, and providing a better user experience.
[0029] In some embodiments, the ratio of the projected area of the heating wire 32 on the insulating plate 31 to the surface area of the insulating plate 31 can be 30%, 40%, 50%, 60%, 70%, or any value between any two of the above, and is not limited thereto.
[0030] Preferably, the ratio of the projected area of the heating wire 32 on the insulating plate 31 to the surface area of the insulating plate 31 is greater than 50%. In this way, heating efficiency is higher while ensuring uniform heating.
[0031] The insulating plate 31 is annular, and the heating wire 32 is wound radially and evenly distributed circumferentially on the insulating plate 31. In this way, the food in the stirring cup 61 is heated more evenly.
[0032] The insulating plate 31 is provided with a plurality of slots 313 evenly distributed on its inner and outer sides along the radial direction, and the heating wire 32 is confined within the slots 313; and / or, the heating wire is evenly distributed on the insulating plate along the circumference. By providing the slots 313, the heating wire 32 can be confined, preventing the heating wire 32 from shifting on the insulating plate 31 during use, thereby ensuring that the heating wire 32 is always evenly wound on the insulating plate 31.
[0033] In the illustrated embodiment, the insulating plate 31 includes a semi-annular first insulating plate 311 and a second insulating plate 312, which are arranged opposite to each other, making the insulating plate 31 annular. The heating wire 32 is uniformly wound around the first insulating plate 311 and the second insulating plate 312. Specifically, the first insulating plate 311 and the second insulating plate 312 are uniformly provided with a plurality of slots 313 on their inner and outer sides, and the heating wire 32 is confined within the slots 313. In another embodiment, the insulating plate 31 is entirely annular.
[0034] In the illustrated embodiment, the insulating and heat-insulating layer 40 includes an insulating layer 41 adjacent to the heating layer 30 and a heat-insulating layer 42 adjacent to the insulating layer 41. Thus, the insulating layer 41 provides insulation to the heating wire 32, while the heat-insulating layer 42 provides heat insulation, reducing downward heat conduction. In another embodiment, the insulating and heat-insulating layer 40 is a single unit, providing both insulation and heat insulation.
[0035] The insulating layer 41 is made of mica sheet, and its thickness ranges from 0.3 mm to 1 mm. This results in low cost and facilitates a reduction in the thickness of the heating plate assembly 62. In some embodiments, the thickness of the insulating layer 41 can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, or any value between any two adjacent values. The heat insulation layer 42 is made of mica sheet or glass fiber. This results in low cost and good heat insulation performance.
[0036] The chassis 10 is made of metal, and its thickness ranges from 0.3 mm to 2 mm. This provides good heat transfer. In some embodiments, the thickness of the chassis 10 can be 0.3 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, 1.5 mm, 1.7 mm, 1.9 mm, 2 mm, or any value between any two adjacent values. In a preferred embodiment, the chassis 10 is made of food-grade stainless steel. In other embodiments, the chassis 10 is made of aluminum alloy or other materials, and is not limited thereto.
[0037] The insulating heat transfer layer 20 is made of alumina sheet or mica sheet, and the thickness of the insulating heat transfer layer 20 ranges from 0.4 mm to 2.0 mm. This results in good heat transfer performance and low cost. In some embodiments, the thickness of the insulating heat transfer layer 20 can be 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, or any value between any two adjacent values mentioned above.
[0038] The insulating plate 31 is made of mica sheet, and its thickness ranges from 0.3 mm to 1 mm. Because mica sheet has low hardness, the heating wire 32 is wound around it, which helps maintain good performance and extends its service life. In some embodiments, the thickness of the insulating plate 31 can be 0.3 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, or any value between two adjacent values.
[0039] The heating plate assembly also includes two terminals 39 and two insulating sleeves 38. Each of the two terminals 39 passes through the insulating and heat-insulating layer 40 and is connected to both ends of the heating wire 32. The two insulating sleeves 38 are respectively fitted onto the two terminals 39. Thus, the insulating sleeves 38 provide insulation and heat insulation for the terminals 39. In one embodiment, the insulating sleeves 38 are made of ceramic, but are not limited to this.
[0040] The heating plate assembly 62 further includes a fixing member 50. The base 10 includes a plate body 12 and surrounding ribs 11 around the plate body 12. The fixing member 50 is fixed to the surrounding ribs 11, confining the insulating heat transfer layer 20, the heating layer 30, and the insulating heat insulation layer 40 between the plate body 12 and the fixing member 50. This makes the assembly of the heating plate assembly 62 convenient and reliable. In some embodiments, the fixing member 50 and the surrounding ribs 11 can be fixed by welding, snap-fitting, or other methods.
[0041] The heating plate assembly 62 also includes a reinforcing heat insulation layer 55 disposed on the side of the fixing member 50 away from the insulating heat insulation layer 40. By providing the heating heat insulation layer 55, the heat generated by the heating layer 30 is further reduced from being conducted away from the base 10, while allowing more heat to be conducted towards the base 10, resulting in higher heating efficiency for food.
[0042] The heating plate assembly 62 also includes a temperature sensor 19 fixed to the chassis 10 by a nut. The temperature sensor 19 is used to sense the temperature of the chassis 10 and transmit the temperature signal to the control circuit board (not shown).
[0043] The food processor 100 includes a soundproof cover 69 that covers the mixing cup assembly 60, and the soundproof cover 69 is supported on the base 70. Thus, the soundproof cover 69 can effectively reduce the noise generated by the food processor 100 during operation.
[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
