[0038] Please refer to Figure 3 and Figure 4 , Figure 3 for Figure 2 the exploded view of the heating disc 211 and the stirring blade 23. Figure 4 is the cross-sectional view of the heating disc 211 and the stirring blade 23 in the assembled state.

[0039] The heating disc 211 comprises a disc body 25 and a heating part 26, the disc body 25 is sealingly engaged with the bottom end of the cup body 210 as the cup bottom of the cup body 210, and the disc body 25 and the cup body 210 together enclose the cup cavity. The heating part 26 can generate heat, and the heating part 26 is in contact with the disc body 25 to transfer heat to the disc body 25. The heating disc 211 further comprises a sealing ring 27, a temperature controller 28 and a temperature sensor 29, the sealing ring 27 is used to seal the gap between the disc body 25 and the cup body 210 at the opening. The temperature controller 28 can control the on-off of the heating part 26 according to the temperature threshold, and the temperature sensor 29 is used to detect the temperature in the cup cavity.

[0040] The disc body 25 comprises a bottom wall 251 located at the center and a side wall 252 connected to the peripheral edge of the bottom wall 251, the side wall 252 is tilted upward relative to the bottom wall 251, and the disc body 25 has a downward convex disc structure.

[0041] The heating part 26 comprises a heating tube 260 and a heat conducting member 261, the heating tube 260 can generate heat when powered on, the heating tube 260 is in thermal conduction with the heat conducting member 261, and the heating tube 260 can be welded to the lower surface of the heat conducting member 261, but is not limited thereto. The heat conducting member 261 is also in thermal conduction with the disc body 25, and the disc body 25 is in contact and engagement with the upper surface of the heat conducting member 261, and the engagement mode includes but is not limited to welding. The heat conducting member 261 is configured such that the heat transferred by the heat conducting member 261 to the bottom wall 251 is less than the heat transferred by the heat conducting member to the side wall 252. For example, the bottom wall 251 is made of a material with poor thermal conductivity, including but not limited to ceramic material and the like. The side wall 252 is made of a material with good thermal conductivity, including but not limited to metal material.

[0042] According to the above description, the heat conducting member 261 is used to transfer the heat of the heating tube 260 to the disc body 25, and the heat conducting member 261 is configured to transfer less heat to the bottom wall 251 than to the side wall 252, so as to reduce the temperature of the bottom wall 251 and reduce the problem of food materials being squeezed and adhered to the bottom wall 251.

[0043] In one embodiment, as shown in Figure 4 The heat-conducting member 261 is in the shape of a disc, including a disc bottom 2610 at the center and a side wall 2611 connected to the four peripheral edges of the disc bottom 2610.

In this way, the side wall 2611 and the disc bottom 2610 are made of two materials with different thermal conductivities, which can reduce the heat transferred from the disc bottom 2610 to the bottom wall 251, thereby reducing the problem of sticking to the bottom. The disc bottom 2610 is made of a material with low thermal conductivity, including but not limited to ceramic and plastic. The side wall 2611 is made of a material with high thermal conductivity, including but not limited to stainless steel and glass.

For example, M1:M2 can be 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8. In this way, the area of the side wall 252 accounts for a large proportion, and this scheme can improve the heating efficiency of the side wall 252. Further, 0.4≤M1:M2≤0.6.

[0046] Please refer to Figure 4 and Figure 5 In one embodiment, the bottom wall 251 is arranged as a circular bottom wall, and the disc body 25 is cut by a plane where the center axis O of the bottom wall 251 is located. The intersection line A between the plane and the inner surface of the side wall 252 is an arc curve convex away from the center axis O, or a diagonal line gradually away from the center axis O of the bottom wall 251. In this way, the diameter of the top end of the side wall 252 is greater than the diameter of the bottom wall 251, and the disc body 25 is in the shape of a conical disc with a large upper part and a small lower part. The bottom wall 251 has a small area, which is beneficial to prevent sticking to the bottom.

[0047] In one embodiment, the obtuse angle between the line L connecting the lowest point and the highest point of the intersection line and the bottom wall is a, and 90°≤a≤160°. The angle is appropriately sized, and accordingly, the inclination of the side wall 252 toward the outside is appropriately sized. Further, 105°≤a≤135°. In one specific embodiment, a can be 90°, 100°, 105°, 110°, 120°, 130°, 135°, 140°, 150°, 160°, but is not limited thereto.

The axis of the blade shaft 230 coincides with the central axis O. Figure 4

[0049] The distance between the end of the first blade leaf 231 along the axial direction of the blade shaft and the bottom wall 251 is L1, and the distance between the lowermost end of the heating tube 260 along the axial direction of the blade shaft and the bottom wall 251 is L2, wherein 1 / 4≤L1:L2≤3 / 4. The ratio size can appropriately size the gap between the first blade leaf 231 and the bottom wall 251, and the stirring by the first blade leaf 231 can prevent the paste from sticking to the bottom wall 251, avoid contact with the bottom wall 251, and ensure high heat transfer efficiency. Further, 0.3≤L1:L2≤0.6. L1:L2 can be 0.25, 0.3, 0.4, 0.5, 0.6, 0.75.

L2 can be set to 6mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, but is not limited thereto. In this way, L1 and L2 are relatively small in size, which can appropriately size the gap between the first blade leaf 231 and the bottom wall 251 of the disc body 25, the height of the side wall 252, and ensure high heat transfer efficiency.

[0051] ​In an embodiment, 5mm≤L1≤25mm, 6mm≤L2≤60mm. For example, L1 can be set to 5mm, 8mm, 12mm, 14mm, 16mm, 18mm, 20mm, 25mm, but not limited to. L2 can be set to 6mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, but not limited to. In this way, L1 and L2 are relatively large, which can make the gap between the first blade 231 and the bottom wall 251 appropriate, the height of the side wall 252 appropriate, and ensure high heat transfer efficiency.

[0052] In an embodiment, the distance between the end of the first blade 231 and the side wall 252 of the disc body 25 along the radial direction of the blade shaft is P1, and the single-side dimension of the side wall 252 in the projection of the blade shaft along the axial direction is P2, 1 / 10≤P1:P2≤3 / 5. This ratio can make the gap between the first blade 231 and the side wall 252 of the disc body 25 appropriate, and avoid contact with the side wall 252. Further, 0.15≤P1:P2≤0.4. P1:P2 can be 0.1, 0.15, 0.2, 0.3, 0.4, 0.5, 0.6.

[0053] In an embodiment, 3mm≤P1≤25mm, 5mm≤P2≤30mm. In this way, the gap between the first blade 231 and the side wall 252 is small, and the situation of food material sticking to the side wall 252 is less likely to occur. For example, P1 can be set to 3mm, 5mm, 10mm, 15mm, 20mm, 25mm, but not limited to. P2 can be set to 5mm, 10mm, 20mm, 30mm, but not limited to.

[0054] In an embodiment, 3mm≤P1≤25mm, 5mm≤P2≤60mm. In this way, the single-side dimension of the bottom wall 251 is reduced, and the single-side dimension of the side wall 252 is appropriately increased, which can reduce the problem of sticking to the bottom. For example, P1 can be set to 3mm, 5mm, 10mm, 15mm, 20mm, 25mm, but not limited to. P2 can be set to 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, but not limited to.

[0057] InFigure 6 In the illustrated embodiment, the heat-conducting member 261 is in a hollow ring shape, and is sleeved on the outer side of the side wall 252 and in thermal conduction with the side wall 252. In this embodiment, the middle region of the heat-conducting member 261 is hollow, and the heat-conducting member 261 is in thermal conduction with the side wall 252 only, and transmits heat to the bottom wall 251 through the side wall 252, so that the bottom wall 251 is in a low-temperature heating area, thereby reducing the problem of food material sticking to the bottom.

For example, 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm. The wall thickness D is relatively small, and the heat loss can be correspondingly reduced. Further, 0.5mm≤D≤3mm.
