Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of small household appliances, and in particular to a heating disc assembly and a food processor. BACKGROUND

[0002] The food processor comprises a heating disc assembly. The heating disc assembly comprises a disc body and a heating tube. The disc body is in the form of a flat plate. The heating tube is in the form of a C shape. In this way, after the heating element is installed on the bottom surface of the disc body, the heating element extends around the circumference of the disc body, and the two end portions of the heating element are opposite to each other to form an open cold end region.

[0003] When the above-mentioned heating disc assembly is heated, the two ends of the heating tube are usually used for wiring and the like, and are usually at a relatively low temperature. In addition, because the end portions are opposite to each other in the C-shaped heating tube, the cold end region is relatively large, so that the temperature of the cold end region is higher than that of the cold end region, forming a local high temperature. During cooking, if a large amount of food is accumulated on the disc body, the problem of burnt bottom will occur. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to disclose a heating disc assembly and a food processor. The heating disc assembly can avoid burnt bottom.

[0005] The present application discloses a heating disc assembly. The heating disc assembly comprises a disc body and a heating element. The disc body comprises a disc body bottom wall and a disc body side wall surrounding the disc body bottom wall, and the disc body bottom wall and the disc body side wall enclose a disc body cavity. The heating element is arranged on the outer wall surface of the disc body side wall in the circumferential direction of the disc body side wall, and the outer wall surface is opposite to the disc body cavity. The heating element comprises a main body segment and first and second connecting segments at two ends of the main body segment. At least one of the first and second connecting segments is deflected upward or downward relative to the main body segment along the disc body side wall. At least the main body segment of the main body segment, the first connecting segment and the second connecting segment constitutes a heating part of the heating element. The orthographic projection of the heating part of the heating element on the disc body bottom wall is in the form of an arc, and the corresponding central angle is θ, θ≥330 degrees.

[0006] As set forth above, since at least one of the first connecting section and the second connecting section is deflected upward or downward along the side wall of the disc body relative to the main section, and at least the main section of the main section, the first connecting section and the second connecting section constitutes the heating part of the heating element, so that the original position of the deflected first connecting section and / or second connecting section on the disc body side wall can be used to set some heating parts, thereby the heating part is longer, so that θ≥330 degrees (it can be understood that the cold end region is less than 30 degrees, and the cold end region is reduced), so that during the heating process of the heating element, one or nearly one (the region less than 30 degrees can quickly pass through heat transfer to make the temperature equal to the temperature corresponding to the heating part) of the disc body side wall is heated, so that the local high temperature of the disc body side wall is avoided. On this basis, the disc body side wall is uniformly heated, and the heat transfer to the disc body bottom wall also makes the disc body bottom wall be uniformly heated. As described above, the above setting avoids that the disc body side wall and the disc body bottom wall (i.e. the disc bottom) are burned due to local high temperature. In addition, the deflection of at least one of the first connecting section and the second connecting section relative to the main section will not be located in the area surrounded by the main section, which is also beneficial to wiring and the like.

[0007] In some embodiments, the heating part of the heating element has a closed annular shape in the orthographic projection on the disc body bottom wall.

[0008] As set forth above, since the heating part of the heating element has a closed annular shape in the orthographic projection on the disc body bottom wall, so that at least the whole of the disc body side wall is heated, there is no cold end region, which can further avoid local high temperature, heat more uniformly, and can improve the heating efficiency.

[0009] In some embodiments, the main section constitutes the heating part, or a part of at least one of the first connecting section and the second connecting section and the main section constitute the heating part.

[0010] As set forth above, in the case that the first connecting section and the second connecting section at least one part and the main section 21 constitute the heating part, the part belonging to the cold end in the first connecting section and the second connecting section is very small, which is beneficial to realize the minimum cold end, and further better avoid local high temperature.

[0011] In some embodiments, the heating part is arranged around the disc body side wall, which is a circular ring; or the heating part is arranged in a spiral shape along the disc body side wall.

[0012] As set forth above, since the heating portion is a circular ring, the orthographic projection is a closed ring, or, is arranged spirally along the side wall of the disc body, the orthographic projection is a closed ring, the heating portion has at least one circle, and there is no cold end region, so that the side wall of the disc body can be uniformly heated; in the case of arranging the heating portion spirally along the side wall of the disc body, the heating region is more, and local high temperature can be avoided, and the heating efficiency can be improved.

[0013] In some embodiments, the angle at which at least one of the first connecting section and the second connecting section is deflected relative to the main section is β, and 90 degrees ≤ β ≤ 135 degrees.

[0014] As set forth above, since 90 degrees ≤ β ≤ 135 degrees, the first connecting section and / or the second connecting section are more convenient to be deflected, and the like, and the heating element is convenient to be processed, in addition, 90 degrees ≤ β ≤ 135 degrees is also convenient for wiring.

[0015] In some embodiments, the side wall of the disc body includes a side wall top end relative to the disc body bottom wall, the heating element is located at the side wall top end, and at least one of the first connecting section and the second connecting section extends along the side wall of the disc body towards the disc body bottom wall.

[0016] As set forth above, since the heating element is located at the side wall top end and is arranged circumferentially around the side wall of the disc body, and at least one of the first connecting section and the second connecting section extends along the side wall of the disc body towards the disc body bottom wall, the heating element is far away from the disc body bottom wall, the heat generated by the heating element is transmitted to the disc body bottom wall through the side wall of the disc body, the disc body bottom wall is uniformly heated, and the disc body cavity bottom surface is less likely to be burnt. In addition, when the heating element is farther away from the disc cavity bottom surface, the food in the disc cavity is heated by heating the water, and the disc cavity bottom surface is less likely to be burnt.

[0017] In some embodiments, the heating disc assembly includes a knife assembly, the knife assembly includes a knife shaft rotationally assembled with the disc body bottom wall and a plurality of knife leaves assembled on the knife shaft, and at least part of the plurality of knife leaves is located in the disc cavity.

[0018] As set forth above, since at least part of the plurality of knife leaves is located in the disc cavity, the knife leaves rotate to generate turbulence, the turbulence makes the food flow, so that the disc cavity bottom surface and the disc cavity side surface are less likely to stick to the food and be burnt, and the burnt bottom is further avoided.

[0019] In some embodiments, the disc cavity includes a disc cavity bottom surface and a disc cavity side surface surrounding the disc cavity bottom surface; the disc cavity side surface is inclined outward from the disc cavity bottom surface; the plurality of blades includes a lowest blade tip in the axial direction of the blade shaft; the distance between the lowest blade tip and the disc cavity side surface in the radial direction of the blade shaft is P1; the projection of the disc cavity side surface on the radial plane of the blade shaft has a width of P2, and 0.1≤P1 / P2≤0.6; or, the disc cavity side surface and the disc cavity bottom surface form a cylinder, and the distance between the lowest blade tip and the disc cavity side surface in the radial direction of the blade shaft is P1, and 3mm≤P1≤20mm.

[0020] As arranged above, the heating element can uniformly heat the disc side wall, and in combination with 0.1≤P1 / P2≤0.6, the distance between the disc cavity side surface and the blade is not too far, so that the disturbance of the blade (at least the disturbance of the lowest blade tip) can more effectively act on the heating area of the disc cavity side surface corresponding to the heating element, and the stirring effect of the food is good, so that the food has good flowability, thereby, the combination of uniform heating and good flowability avoids the food from sticking to the disc cavity side surface and being burnt. In addition, the heating element is arranged around the circumference of the disc side wall, the disc side wall is first heated, the disc side wall is uniformly heated, the heat can be uniformly transmitted to the disc bottom wall through the disc side wall, the disc bottom wall is uniformly heated, and the flowability of the food is good due to the disturbance of the blade, so that the disc cavity bottom surface is not burnt by the food. In summary, the above arrangement can avoid the problem of poor flowability of the food and accumulation of the food on the disc bottom to cause burning, and improve the user experience. In the case where the disc cavity side surface and the disc cavity bottom surface form a cylinder, 3mm≤P1≤20mm, the stirring effect of the blade is good, the flowability of the food is good, and the disc cavity side surface can also be avoided from being burnt by the food, thereby, the disc cavity side surface and the disc cavity bottom surface of the disc are avoided from being burnt, and the user experience is improved.

[0021] In some embodiments, in the case where 0.1≤P1 / P2≤0.6, 3mm≤P1≤25mm, and 5mm≤P2≤60mm.

[0022] As arranged above, in the case where 0.1≤P1 / P2≤0.6, 3mm≤P1≤25mm, and 5mm≤P2≤60mm, the stirring effect of the blade is good, the flowability of the food is better, and the disc cavity side surface and the disc cavity bottom surface are avoided from being burnt.

[0023] In some embodiments, the disc cavity includes a disc cavity bottom surface and a disc cavity side surface surrounding the disc cavity bottom surface; the disc cavity side surface includes a bottom edge connected to the disc cavity bottom surface and a top edge opposite to the bottom edge; the included angle between the plane passing through the top edge and the bottom edge and the disc cavity bottom surface is α, and 90 degrees≤α≤170 degrees.

[0024] As set forth above, in the case of 90 degrees ≤ α ≤ 170 degrees, the disturbance generated by the blades makes the stirring effect good, and the flowability of the food is good, thereby avoiding the side wall and the bottom wall of the cavity of the disc body from being burnt by the food.

[0025] In some embodiments, the cavity of the disc body includes a bottom wall of the cavity of the disc body, the distance between the top of the heating element and the bottom wall of the cavity of the disc body is L2 along the axial direction of the blade shaft; the plurality of blades includes a lowest blade tip; the distance between the lowest blade tip and the bottom wall of the cavity of the disc body is L1; 0.25 ≤ L1 / L2 ≤ 0.75.

[0026] As set forth above, since 0.25 ≤ L1 / L2 ≤ 0.75, the heating area corresponding to the heating element on the side wall of the cavity of the disc body is heated by the heating element, and this part of the area is closer to the disturbance area of the blades, and the disturbance of the blades (at least the disturbance generated by the blade with the lowest blade tip) more effectively acts on the heating area, the stirring effect of the blades is good, and the flowability of the food is better, and thus, the side wall of the cavity of the disc body is more capable of avoiding being burnt by the food, and correspondingly, the bottom wall of the cavity of the disc body is also capable of avoiding being burnt by the food.

[0027] In some embodiments, the heating element is in contact with the outer surface of the side wall of the disc body to form a contact surface; the plurality of blades includes a lowest blade tip along the axial direction of the blade shaft; and the lowest blade tip is located between the top edge and the bottom edge of the contact surface.

[0028] As set forth above, the lowest blade tip is located between the top edge and the bottom edge of the contact surface, and the heating area corresponding to the heating element on the side wall of the cavity of the disc body is more within the disturbance area of the blades (especially the disturbance area of the blade with the lowest blade tip), and thus, the stirring effect of the disturbance generated by the blades on the food is good, and the flowability of the food is better, and the side wall of the cavity of the disc body is more capable of avoiding being burnt by the food. Of course, the side wall of the disc body will not be burnt, and after the side wall of the disc body is heated by the heating element, the heat is transferred to the bottom wall of the disc body to heat the food, and the heat transfer is relatively uniform, and in combination with the stirring of the blades, the bottom wall of the disc body is capable of avoiding being burnt, and as described above, the side wall and the bottom wall of the disc body are capable of avoiding being burnt by the food according to the above setting.

[0029] In a second aspect, the present application discloses a food processor. The food processor includes a control panel and any one of the aforementioned heating disc assemblies. The control panel is electrically connected with the first connecting section and the second connecting section of the heating element to control the heating of the heating element.

[0030] As set forth above, the food processor has at least the beneficial effects of the heating disc assembly. BRIEF DESCRIPTION OF DRAWINGS

[0045] The technical solutions in the embodiments (or, “embodiments”) of the present application will be described clearly and completely with reference to the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0046] If the application embodiments involve the terms of direction indication or position relationship (for example, up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative position relationship, motion condition, etc. between components in a certain posture (as shown in the drawings); if the specific posture changes, the direction indication or position relationship will also change accordingly. In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0047] Referring to Figures 4 to 6 in combination with Figure 2 and Figure 3 , the application discloses a heating disc assembly 10. The heating disc assembly 10 comprises a disc body 1 and a heating element 2. Figure 4 It is also shown that the heating disc assembly 10 comprises a knife assembly 5, a temperature controller 901, an NTC 902 and a sealing ring 8. The sealing ring 8 is used to seal the food stirring cavity formed by the disc body 1 of the heating disc assembly 10 and the stirring cup 20, so as to prevent water leakage and the like. The disc body 1 comprises a disc body bottom wall 11 and a disc body side wall 12 surrounding the disc body bottom wall 11. The disc body bottom wall 11 and the disc body side wall 12 form a disc body cavity 13. The disc body cavity 13 comprises a disc body cavity bottom surface 131 and a disc body cavity side surface 132 surrounding the disc body cavity bottom surface 131. That is, the disc body cavity bottom surface 131 is the inner surface of the disc body bottom wall 11. The disc body cavity side surface 132 is the inner surface of the disc body side wall 12. The structure of the disc body 1 is not limited, and can be, for example, Figure 6 and Figure 4 As shown, the disc body 1 comprises an inner disc body 141 and a heat-conducting disc 142, at this time, the side surface of the inner disc body 141 is the disc body cavity side surface 132, and the bottom surface of the inner disc body 141 is the disc body cavity bottom surface 131. The inner disc body 141 is, for example, a food-grade stainless steel disc. The heat-conducting disc 142 can be an aluminum disc, which can conduct heat. In some embodiments, the disc body 1 can also have a single-layer structure.

[0048] Referring to Figures 4 to 10The heating element 2 is arranged on the outer wall surface of the disc body side wall 12, which is opposite to the disc body cavity 13. The heating element 2 comprises a main body segment 21 and a first connecting segment 22 and a second connecting segment 23 at both ends of the main body segment 21. The structure of the main body segment 21 is not limited, which can be an arc in the mathematical sense as shown in the figure, or can comprise a straight segment and two arc segments, one end of the straight segment being connected to one arc segment, and the other end of the straight segment being connected to the other arc segment, and the like will not be listed one by one. The first connecting segment 22 and the second connecting segment 23 are used for wiring and the like. The first connecting segment 22 is deflected downward along the disc body side wall 12 relative to the main body segment 21, and how to deflect downward is not limited. In other embodiments, the first connecting segment 22 and the second connecting segment 23 can both be deflected downward along the disc body side wall 12 relative to the main body segment 21. Alternatively, the second connecting segment 23 is deflected downward relative to the main body segment 21. Of course, the skilled person can understand that in some embodiments, it can be upward deflection.

[0049] Referring to Figure 7 and Figure 8 in combination with Figure 4 and Figure 5 , of the main body segment 21, the first connecting segment 22 and the second connecting segment 23, the main body segment 21 and a part of the first connecting segment 22 constitute a heating part of the heating element 2. Figure 9 and Figure 10 In some embodiments, the main body segment 21, a part of the first connecting segment 22 and a part of the second connecting segment 23 constitute the heating part, and in summary, a part of at least one of the first connecting segment 22 and the second connecting segment 23 and the main body segment 21 constitute the heating part. In the case where a part of at least one of the first connecting segment 22 and the second connecting segment 23 and the main body segment 21 constitute the heating part, the part belonging to the cold end in the first connecting segment 22 and the second connecting segment 23 is small, which is beneficial to realize the minimum cold end, and in turn, better avoid local high temperature. In yet another embodiment, only the main body segment 21 constitutes the heating part. In summary, of the main body segment 21, the first connecting segment 22 and the second connecting segment 23, at least the main body segment 21 can constitute the heating part of the heating element. Regardless of the embodiment, the heating part is used to heat the disc body side wall 12. The orthographic projection of the heating part of the heating element 2 on the disc body bottom wall 11 is arc-shaped. Although Figures 7 to 9 The orthographic projection of the heating part of the heating element 2 shown is a circular ring (a circular ring is a closed ring), as long as it is a closed ring. The skilled person can understand that, referring to Figure 10In some embodiments, the orthographic projection of the heating portion of the heating element 2 can also be a non-closed ring. Regardless of whether it is a closed or non-closed ring, the central angle corresponding to the orthographic projection of the heating portion is θ, where θ ≥ 330 degrees, for example, 330 degrees, 335 degrees, 338 degrees, 340 degrees, 342 degrees, 345 degrees, 348 degrees, 350 degrees, 353 degrees, 355 degrees, or 358 degrees, etc. In the case of a closed ring, the central angle θ = 360 degrees.

[0050] As set above, and Figure 13 The first and second connecting segments shown do not bend relative to the main body segment, but together form a C-shaped heating element. Figure 13 Compared to the previous method (where the central angle θ is 270 degrees and the cold end region 24 is 90 degrees), since at least one of the first connecting segment 22 and the second connecting segment 23 is deflected upwards or downwards relative to the main body segment 21 along the sidewall 12 of the disk body, and at least the main body segment 21 constitutes the heating portion of the heating element, the original position of the deflected first connecting segment and / or second connecting segment on the sidewall of the disk body can be used to set the heating portion, making the heating portion longer so that θ≥330 degrees, that is, compared to Figure 13 Compared to the previous configuration, the cold end region 24 is smaller or nonexistent. Therefore, during the heating process of the heating element 2, the entire perimeter or nearly perimeter of the sidewall 12 of the disc (the smaller cold end region can quickly achieve the same temperature as the corresponding heated area through heat transfer) is heated, thus preventing localized high temperatures on the sidewall 12. Furthermore, the heating of the sidewall 12, and the subsequent heat transfer to the bottom wall 11, also ensures uniform heating of the bottom wall 11. In summary, the above configuration prevents the sidewall 12 and the bottom wall 11 (i.e., the bottom of the disc) from being burned due to localized high temperatures. In addition, at least one of the first connecting section 22 and the second connecting section 23 is deflected relative to the main body section 21 and is not located within the area of ​​the main body section 21, which also facilitates wiring, etc.

[0051] See Figure 7 and Figure 9 The heating portion of the heating element 2, when projected onto the bottom wall 11 of the disk, forms a closed ring. A circle is one type of closed ring; for example, the aforementioned straight line segment and two arc segments form a closed ring.

[0052] As described above, since the heating part of the heating element 2 has a closed ring shape on the bottom wall of the plate, the side wall of the plate is heated at least around the entire circumference, there is no cold end area, which can better avoid local high temperature, make the heating more uniform, and improve the heating efficiency.

[0053] In other embodiments, the heating element is arranged in a ring around the side wall of the disc body, see [link to previous embodiment].Figure 7 The second connecting section 23, the main body section 21 and a part of the first connecting section 22 form a circular ring. See Figure 9 The main body section 21 and a part of the second connecting section 23 form a circular ring. In yet some embodiments, the heating section is arranged helically around the side wall 12 of the disc body.

[0054] As arranged above, the two embodiments above, because the heating section is at least one circle, there is no cold end region 24 as shown in Figure 13 all can avoid local high temperature, and avoid the purpose of burnt bottom. In the case of helically arranging the heating section around the side wall 12 of the disc body, the heating region is more, and can avoid local high temperature, and can improve the heating efficiency.

[0055] See Figures 4 to 10 Of the first connecting section 22 and the second connecting section 23, only the first connecting section 22 is deflected upward or downward relative to the main body section 21, of course, only the second connecting section 23 can be deflected upward or downward relative to the main body section 21.

[0056] As arranged above, because only one of the first connecting section 22 and the second connecting section 23 is deflected upward or downward relative to the main body section 21, there is more operating space between the first connecting section 22 and the second connecting section 23, which is convenient for wiring and the like.

[0057] See Figure 8 and Figure 9 The angle of the first connecting section 22 deflected downward relative to the main body section 21 is β, 90 degrees ≤ β ≤ 135 degrees, such as 90 degrees, 92 degrees, 5 degrees, 98 degrees, 100 degrees, 102 degrees, 105 degrees, 108 degrees, 110 degrees, 112 degrees, 125 degrees, 128 degrees, 130 degrees, 133 degrees or 135 degrees. In other embodiments, when the second connecting section 23 is deflected upward or downward relative to the main body section 21, the included angle between the second connecting section 23 and the main body section 21 can also be the above-mentioned β. Of course, the angle of the second connecting section 23 deflected relative to the main body section 21 can be equal to or different from the angle of the first connecting section 22 deflected relative to the main body section 21. In short, the angle of at least one of the first connecting section 22 and the second connecting section 23 deflected relative to the main body section 21 is β.

[0058] As arranged above, because 90 degrees ≤ β ≤ 135 degrees, the first connecting section 22 and / or the second connecting section 23 are more convenient for deflection upward or downward and the like, and the processing of the heating element 2 is facilitated, in addition, 90 degrees ≤ β ≤ 135 degrees is also convenient for wiring.

[0059] See Figure 6 and in combination with Figure 3The side wall 12 of the disc body includes a side wall top end 121 opposite to the bottom wall 11 of the disc body. The heating element 2 is located at the side wall top end 121. The first connecting section 22 extends along the side wall 12 of the disc body towards the bottom wall 11 of the disc body. In other embodiments, the second connecting section 23 can extend along the side wall 12 of the disc body towards the bottom wall 11 of the disc body. In summary, at least one of the first connecting section 22 and the second connecting section 23 extends along the side wall 12 of the disc body towards the bottom wall 11 of the disc body.

[0060] As shown in the above arrangement, since the heating element 2 is located at the side wall top end 121, and at least one of the first connecting section 22 and the second connecting section 23 extends along the side wall 12 of the disc body towards the bottom wall 11 of the disc body, the heating element 2 is far away from the bottom wall 11 of the disc body. The heat generated by the heating element 2 is transferred to the bottom wall 11 of the disc body through the side wall 12 of the disc body. The side wall 12 of the disc body is uniformly heated, which is easy to make the bottom wall 11 of the disc body uniformly heated, and the bottom surface 131 of the disc cavity 13 is less likely to be burnt. Figure 8 In addition, when the heating element 2 is far away from the bottom surface 131 of the disc cavity 13, as shown in the above arrangement, the food in the disc cavity 13 is heated by heating the water, which can further avoid the bottom surface 131 of the disc cavity 13 from being burnt. Figure 7 In addition, in the case that the part of the first connecting section 22 and the second connecting section 23 at least one of which also serves as a part of the heating portion, the extension of at least one of the first connecting section 22 and the second connecting section 23 along the side wall 12 of the disc body can also expand the heating range, and further, it is beneficial to avoid local high temperature.

[0061] Referring to Figure 3 and Figure 6 , the heating disc assembly 10 includes a knife assembly 5. In some embodiments, the heating disc assembly 10 can not include the knife assembly 5. The knife assembly 5 includes a knife shaft 52 rotatably assembled with the bottom wall 11 of the disc body and a plurality of knife leaves 53 assembled on the knife shaft 52. At least part of the plurality of knife leaves 53 is located in the disc cavity 13. In the embodiments of the present application, the knife assembly 5 includes a bearing seat 51 which can be welded with the bottom wall 11 of the disc body. The knife shaft 52 is assembled with the bearing seat 51 through bearings or the like, so as to realize the rotatable assembly of the knife shaft 52 with the bottom wall 11 of the disc body. In the present application, the knife leaves 53 include first knife leaves 531 and second knife leaves 532. The first knife leaves 531 and the second knife leaves 532 each have two leaves, so that, as shown in the above arrangement, the knife assembly 5 is a four-leaf knife. The number of the knife leaves is not limited thereto, and in some cases, it can also be two leaves, three leaves, etc. In the present embodiment, the first knife leaves 531 have the lowest knife tips 5311, and the second knife leaves 532 have the highest knife tips 5321. Figure 4 Figure 3 and Figure 6 ​The first blade 531 extends into the disc cavity 13 and is entirely located in the disc cavity 13. In other embodiments, only a part of the first blade 531, such as the blade tip, is located in the disc cavity 13, and the other part is located outside the disc cavity 13. In yet other embodiments, all the blades, such as the first blade 531 and the second blade 532, are located in the disc cavity 13. The disc cavity 13 includes a disc cavity bottom surface 131 and a disc cavity side surface 132 surrounding the disc cavity bottom surface 131.

[0062] As described above, since at least a part of the plurality of blades is located in the disc cavity 13, the rotation of the blades generates turbulence, and the turbulence causes the food to flow, so that the disc cavity bottom surface 131 and the disc cavity side surface 132 are not easily stuck with food and burnt, and the burnt bottom effect is further avoided.

[0063] Referring to Figure 6 , along the axial direction of the blade shaft 52, the plurality of blades includes a lowest blade tip 5311, and the first blade 531 includes the lowest blade tip 5311. The disc cavity side surface 132 is inclined outwardly from the disc cavity bottom surface 131. Along the radial direction of the blade shaft 52, the distance between the lowest blade tip 5311 and the disc cavity side surface 132 is P1. The projection of the disc cavity side surface 132 on the radial plane of the blade shaft 52 has a width of P2, and 0.1≤P1 / P2≤0.6. For example, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, or 0.6.

[0064] Referring to Figure 11 and in combination with the following table, Figure 9 the following table is a graph generated based on the following table:

[0065] P1 / P2 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 Number of grains 6 4 2 0 0 3 5 7 P1 / P2 0.5 0.55 0.6 0.65 0.7 Number of grains 11 13 13 18 25

[0066] As can be seen from the above graph and table, when 0.1≤P1 / P2≤0.25, the number of stuck rice shows a downward trend, and when the ratio of P1 / P2 is greater than 0.3, the number of stuck rice shows an upward trend. Further, when the ratio is 0.15≤P1 / P2≤0.4, the number of stuck rice is less than or equal to 5, the anti-burnt effect is optimal, and the anti-stuck effect reaches level 2. When the ratio of P1 / P2 is 0.45, the number of stuck rice is 7; when the ratio is 0.5, the number of stuck rice is 11; when the ratio is 0.55, the number of stuck rice is 13; when the ratio is 0.6, the number of stuck rice is 13; when the ratio is 0.65, the number of stuck rice is 18; and when the ratio is 0.7, the number of stuck rice is 25. In summary, 0.1≤P1 / P2≤0.6.

[0067] As set forth above, due to the heating element 2 being capable of uniformly heating the side wall 12 of the disc body, in combination with 0.1≤P1 / P2≤0.6, the distance between the disc body cavity side surface 132 and the blade is not too far, so that the disturbance of the blade (at least the disturbance generated by the blade of the lowest blade tip 5311) can more effectively act on the heating area of the disc body cavity side surface 132 corresponding to the heating element 2 on the disc body cavity side surface 132, and the stirring effect on the food is good, so that the food has good fluidity, thereby, the combination of uniform heating and good fluidity avoids the food from being burnt on the disc body cavity side surface 132. In addition, the heating element 2 is arranged around the circumference of the side wall 12 of the disc body, the side wall 12 of the disc body is first heated, the side wall 12 of the disc body is uniformly heated, the heat can be uniformly transmitted to the disc body bottom wall 11 through the side wall 12 of the disc body, the disc body bottom wall 11 is uniformly heated, and the disturbance generated by the blade makes the food have good fluidity, so that the disc body cavity bottom surface 131 will not be burnt by the food. In summary, the above-mentioned arrangement can avoid the problem of poor fluidity of the food and accumulation of the food on the disc bottom to burn the bottom, and improve the user experience.

[0068] Based on the inspiration of the foregoing embodiments, the disc body cavity side surface 132 and the disc body cavity bottom surface 131 enclose a cylinder, and correspondingly, the disc body cavity side surface 132 is the side surface of the cylinder, and the disc body cavity bottom surface 131 is the bottom surface of the cylinder, that is, P2=0( Figure 6 The disc body cavity side surface 132 is a vertical surface, rather than an arc surface). In this embodiment, along the radial direction of the blade shaft 52, the distance between the lowest blade tip 5311 and the disc body cavity side surface 132 is P1, and 3mm≤P1≤20mm, such as 3mm, 5mm, 7mm, 8mm, 9mm, 10mm, 12mm, 13mm, 15mm, 16mm, 18mm or 20mm.

[0069] As set forth above, in the case that the disc body cavity side surface 132 and the disc body cavity bottom surface 131 constitute the side surface and the bottom surface of a cylinder, 3mm≤P1≤20mm, the stirring effect of the blade is good, so that the food has good fluidity, and the disc body cavity side surface 132 can also be avoided from being burnt by the food, thereby, the disc body cavity side surface 132 and the disc body cavity bottom surface 131 of the disc body 1 are avoided from being burnt, and the user experience is improved.

[0070] In the case of 0.1≤P1 / / P2≤0.6, 3mm≤P1≤25mm; 5mm≤P2≤60mm. Figure 6 In the case of the disc body cavity side surface 132, 3mm≤P1≤25mm, 5mm≤P2≤30mm. In the case that the width of the disc body cavity bottom surface 131 is narrow, the disc body cavity side surface 132 will be long (for example, it can be considered that the upper bottom surface of a circular truncated cone is the disc body cavity bottom surface 131 which is small), 3mm≤P1≤25mm; 5mm≤P2≤60mm.

[0071] As set forth above, since 3mm≤P1≤25mm; 5mm≤P2≤60mm in the case of 0.1≤P1 / / P2≤0.6, the stirring effect of the blade is good so that the flowability of the food is better, and the disc cavity side surface 132 and the disc cavity bottom surface 131 are prevented from being burnt.

[0072] Referring to Figure 6 and Figure 4 , the disc cavity side surface 132 is inclined outwardly to the disc cavity bottom surface 131 so that the disc cavity 13 gradually increases in the direction away from the disc bottom wall 11 to realize the outward inclination. That is, as shown in Figure 6 , the disc cavity side surface 132 is a rotation surface formed by rotating an arc (a segment of a circle or a segment of an ellipse) around the rotation center line of the blade shaft 52 for one turn. In other embodiments, the outward inclination can also be a rotation surface formed by rotating a straight line inclined to the rotation center line of the blade shaft 52 around the rotation center line for one turn, i.e., the side surface of a circular truncated cone.

[0073] Referring to Figure 14 , in other embodiments, the disc cavity side surface 132 includes a connecting surface 1321 and a cylindrical surface 1322. The top edge of the connecting surface 1321 is connected to the bottom edge of the cylindrical surface 1322. The axis of the cylindrical surface 1322 is the rotation center line of the blade shaft 52. The bottom edge of the connecting surface 1321 is connected to the disc cavity bottom surface 131, and the connecting surface 1321 is inclined outwardly to the disc cavity bottom surface 131 so that the disc cavity 13 gradually increases in the direction away from the disc bottom wall 11 to realize the outward inclination. Here, the shape of the connecting surface 1321 is a rotation surface formed by rotating a circular arc around the rotation center line for one turn, or a rotation surface formed by rotating a straight line inclined to the rotation center line around the rotation center line for one turn (i.e., the side surface of a circular truncated cone), and the disc cavity side wall 12 of this embodiment can be understood as the top end of the disc cavity side wall 12 shown in Figure 6 plus a cylindrical side wall.

[0074] As set forth above, since the disc cavity side surface 132 is inclined outward so that the disc cavity 13 gradually increases in size in a direction away from the disc bottom wall 11, or the connecting surface 1321 of the disc cavity side surface 132 is inclined outward so that the disc cavity 13 gradually increases in size in a direction away from the disc bottom wall 11, on the one hand, the outward inclination of the disc cavity side surface 132 can better utilize the disturbance flow generated by the blade, and the disturbance flow effect is good, so that the food can form an effective circulation path in the disc cavity 13, which helps to bring large food materials to the vicinity of the blade 53 for cutting, so that the flow of food is good, and the disc cavity side surface 132 is prevented from being burned by food, on the other hand, in the case of equal volume of the disc cavity 13, the outward inclination of the disc cavity side surface can make the disc cavity bottom surface 131 smaller, and the disturbance flow can maximize the flow of food to make the liquid and solid mixture circulate more smoothly in the disc cavity 13, so that the flow of food is good, and the disc cavity side surface 132 is prevented from being burned by food, because the disc cavity bottom surface 131 is heated by heat transfer of the disc cavity side surface 132 to heat the food, in combination with the disturbance flow of the blade, the above setting can also prevent the disc cavity bottom surface 131 from being burned. In addition, the intersection of the arc surface and the disc cavity bottom surface 131 does not produce a dead angle, and the disc 1 (i.e., the heating disc assembly 10) is easier to clean.

[0075] Referring to Figure 6 , the disc cavity side surface 132 includes a bottom edge connected to the disc cavity bottom surface 131 and a top edge opposite to the bottom edge. The included angle between the plane passing through the top edge and the bottom edge and the disc cavity bottom surface 131 is α, and 90 degrees ≤ α ≤ 170 degrees, such as 90 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, 150 degrees, 155 degrees, 160 degrees, 165 degrees or 170 degrees. In the case of 90 degrees ≤ α ≤ 170 degrees, the shape of the disc cavity side surface 132 is not limited to the shape of the disc cavity side surface 132 shown in Figure 6 . Figure 12 is a graph generated according to the following table.

[0076] α 90 95 100 105 110 115 120 125 130 Number of grains 11 8 8 6 2 0 3 5 5 α 135 140 145 150 155 160 165 170 Number of grains 8 7 6 8 9 12 15 14

[0077] In Figure 12 , when the included angle α is near 105 degrees-130 degrees, the number of rice grains adhered is within 6, and when the angle α is more than 130 degrees, the number of rice grains adhered exceeds 5.

[0078] As set forth above, in the case of 90 degrees ≤ α ≤ 170 degrees, the disturbance flow generated by the blade makes the stirring effect good, and the flow of food is good, and the disc cavity side surface 132 and the disc cavity bottom surface 131 are prevented from being burned by food.

[0079] Referring to Figure 6The distance between the lowest blade tip 5311 and the bottom surface 131 of the disc cavity is L1. The distance between the top of the heating element 2 and the bottom surface 131 of the disc cavity along the axial direction of the blade shaft 52 is L2. The ratio of L1 to L2 is 0.25≤L1 / L2≤0.75. For example, 0.25, 0.28, 0.3, 0.33, 0.35, 0.38, 0.4, 0.43, 0.45, 0.48, 0.5, 0.52, 0.55, 0.58, 0.6, 0.62, 0.65, 0.68, 0.7, 0.72, 0.73, or 0.75. It should be noted that, Figure 6 The lowest blade tip 5311 is located between the top edge and the bottom edge of the contact surface formed by the heating element 2 and the disc cavity side wall 12 along the axial direction of the blade shaft 52. However, when the ratio of L1 to L2 is 0.25≤L1 / L2≤0.75, the lowest blade tip 5311 can also be lower than the bottom edge of the contact surface.

[0080] As described above, due to 0.25≤L1 / L2≤0.75, the heating region of the heating element 2 on the disc cavity side surface 132 of the disc cavity side wall 12 is heated by the heating element 2. This part of the region is close to the turbulence region of the blade, and the turbulence of the blade (at least the turbulence generated by the blade with the lowest blade tip) more effectively acts on the heating region. The stirring effect of the blade is good, and the flowability of the food is better. Therefore, the disc cavity side surface 132 can be prevented from being burned by food, and the disc cavity bottom surface 131 can also be prevented from being burned by food.

[0081] In some embodiments, L1 and L2 satisfy the following conditions:

[0082] a) 0.3≤L1 / L2≤0.6, for example, 0.3, 0.33, 0.35, 0.38, 0.4, 0.42, 0.45, 0.48, 0.5, 0.52, 0.55, 0.58, or 0.6;

[0083] b) 5mm≤L1≤25mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, or 26mm;

[0084] c) 6mm≤L2≤60mm, for example, 6mm, 8mm, 10mm, 13mm, 15mm, 18mm, 20mm, 23mm, 25mm, 28mm, 30mm, 33mm, 35mm, 38mm, 40mm, 42mm, 45mm, 48mm, 50mm, 52mm, 55mm, 58mm, or 60mm.

[0085] As set forth above, since the L1 and L2 satisfy a) 0.3≤L1 / L2≤0.6; b) 5mm≤L1≤25mm; c) 6mm≤L2≤60mm, the food has better flowability, and the side surface 132 of the cavity of the disc body and the bottom surface 131 of the cavity of the disc body are less likely to be burnt.

[0086] Referring to Figure 6 , the heating element 2 is in contact with the side wall 12 of the disc body to form a contact surface; along the axial direction of the blade shaft 52, the lowest blade tip 5311 is located between the top edge and the bottom edge of the contact surface, as shown in Figure 6 , the top edge is F, the bottom edge is f, and the lowest blade tip 5311 is located between F and f. The lowest blade tip 5311 being located between the top edge and the bottom edge of the contact surface includes the following: 1) Figure 6 , the blade tip 5311 (i.e., the lowest blade tip) of the first blade 531 is located between the top edge and the bottom edge of the contact surface, and the blade tip of the second blade 532 is located outside the cavity 13 of the disc body; 2) all the blade tips 5311 can be located inside the cavity 13 of the disc body, and only the lowest blade tip 5311 is located between the top edge and the bottom edge of the contact surface; 3) all the blade tips can be the lowest blade tips, and each of the lowest blade tips is located between the top edge and the bottom edge of the contact surface.

[0087] As set forth above, the lowest blade tip 5311 is located between the top edge and the bottom edge of the contact surface, and the heating area of the heating element 2 is more in the turbulence area of the blade (especially the turbulence area of the blade 53 with the lowest blade tip), so that the stirring effect of the turbulence generated by the stirring of the blade on the food is good, the flowability of the food is better, and the side surface 132 of the cavity of the disc body is less likely to be burnt. Of course, the side wall of the disc body will not be burnt, and after the heating element heats the side wall of the disc body, the heat is transferred to the bottom wall of the disc body, so that the bottom wall of the disc body heats the food. The heat transfer is relatively uniform, and in combination with the stirring of the blade, the bottom wall of the disc body can be prevented from being burnt. In summary, the above-mentioned arrangement can prevent the side wall of the disc body and the bottom wall of the disc body from being burnt.

[0088] Referring to Figure 1 and in combination with Figure 2 and Figure 3 , in a second aspect, the application discloses a food processor. The food processor comprises a control panel (not shown in the figure) and any one of the aforementioned heating disc assemblies 10. The control panel is electrically connected with the first connecting section 22 and the second connecting section 23 of the heating element 2 to control the heating of the heating element 2. Figure 2 It is also shown that the stirring cup assembly comprises a stirring cup 20, a cup cover 30, a cup seat 40, a bottom cover 50, a first coupler 60, and a handle 70. Figure 1The host 200 includes a control board and a second coupler connected with the control board. When the stirring cup assembly is placed on the host 200, the first coupler 60 is plugged with the second coupler, thereby the control board is connected with the heating element 2, and finally the heating of the heating element 2 is controlled by the control board.
