Description

Technical Field

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

[0002] The food processor includes a heating plate assembly. The heating plate assembly comprises a plate body and a heating tube disposed at the bottom of the plate body. The heating tube heats the food at the bottom. During heating, the food at the bottom has poor flow and tends to accumulate. This can lead to burns when cooking foods high in starch or sugar content due to the concentrated high temperature at the bottom. Utility Model Content

[0003] The purpose of the present application is to disclose a food processor with a heating plate assembly, wherein the heating plate assembly can prevent the bottom of the food from getting burnt.

[0004] In a first aspect, the present application discloses a heating plate assembly. The heating plate assembly includes a plate body, a heating element, and a blade assembly. The plate body includes a plate body bottom wall and a plate body side wall, and the plate body side wall and the plate body bottom wall form a plate body cavity, and the plate body cavity includes a plate body cavity bottom surface and a plate body cavity side surface surrounding the plate body cavity bottom surface. The heating element is arranged circumferentially around the plate body side wall and is located outside the plate body cavity. The blade assembly includes a blade shaft rotatably assembled with the plate body bottom wall and a plurality of blades assembled with the blade shaft; at least part of the plurality of blades is located in the plate body cavity. The side surface of the plate body cavity is inclined toward the outside of the bottom surface of the plate body cavity; along the radial direction of the blade shaft, the distance between the lowest blade tip and the side surface of the plate body cavity is P1; the width of the projection of the side surface of the plate body cavity on the radial plane of the blade shaft is P2, and 0.1≤P1 / P2≤0.6.

[0005] As set up above, since 0.1≤P1 / P2≤0.6, the distance between the side of the disc cavity and the blade will not be too far, so that the turbulence of the blade (at least the turbulence generated by the lowest blade tip) can more effectively act on the heating area on the side of the disc cavity corresponding to the heating element, which has a good stirring effect on the food and makes the food fluidity good, thereby preventing the food from sticking to the side of the disc cavity and getting burnt. In addition, the heating element is arranged circumferentially around the side wall of the disc body, first heating the side wall of the disc body, and the heat is transferred to the bottom wall of the disc body through the side wall of the disc body. The bottom wall of the disc body is evenly heated, and combined with the turbulence generated by the blade, the fluidity of the food is good, and the bottom surface of the disc cavity will not stick to the food and get burnt. In summary, the above setting can avoid the problem of food poor in fluidity and accumulation at the bottom of the disc and getting burnt, thereby improving the user experience.

[0006] In some embodiments, 3 mm ≤ P1 ≤ 25 mm; and / or, 5 mm ≤ P2 ≤ 60 mm.

[0007] As set above, 3mm≤P1≤25mm, and / or, 5mm≤P2≤60mm, the blade has a good stirring effect, and the turbulence generated by the blade makes the food more fluid, avoiding the sides and bottom of the dish cavity from being burned.

[0008] In some embodiments, the side surface of the disc cavity is inclined outwardly toward the bottom surface of the disc cavity, so that the disc cavity gradually increases in a direction away from the bottom wall of the disc body, thereby achieving the outer inclination.

[0009] As set up above, since the side surface of the dish cavity is tilted outward as a whole so that the dish cavity gradually increases in the direction away from the bottom wall of the dish body, or the connecting surface of the side surface of the dish cavity is tilted outward so that the dish cavity gradually increases in the direction away from the bottom wall of the dish body, on the one hand, the outward tilt of the side surface of the dish cavity can better utilize the turbulence generated by the blade, and the good turbulence effect enables the food to form an effective circulation path in the dish cavity, which helps to bring large pieces of food near the blade for cutting, so that the food has good fluidity and avoids the food on the side surface of the dish cavity from being stuck to the food and being burned. On the other hand, when the volume of the dish cavity is equal, the outward tilt of the side surface of the dish cavity can make the bottom surface of the dish cavity smaller, and the turbulence can maximize the fluidity of the food so that the liquid and solid mixture can circulate more smoothly in the dish cavity, so that the food has good fluidity and avoids the food on the side surface of the dish cavity from being stuck to the food and being burned. Because the bottom surface of the dish cavity heats the food through heat transfer from the side surface of the dish cavity, combined with the turbulence of the blade, the above setting can also prevent the bottom surface of the dish cavity from being burned. In addition, no dead angle is generated at the intersection of the arc surface and the bottom surface of the disc cavity, making it easier to clean the disc (that is, the heating disc assembly).

[0010] In some embodiments, the side surface of the disc cavity includes a bottom edge connected to the bottom surface of the disc cavity and a top edge relative to the bottom edge; the angle between the tangent plane passing through the top edge and the bottom edge and the bottom surface of the disc cavity is α, 90 degrees ≤ α ≤ 170 degrees.

[0011] As set above, when 90 degrees ≤ α ≤ 170 degrees, the turbulence generated by the blades makes the stirring effect better, makes the food fluidity better, and prevents the sides and bottom of the dish cavity from being stained with food and being burned.

[0012] In some embodiments, along the axial direction of the blade shaft, the distance between the top of the heating element and the bottom surface of the disc cavity is L2; ​​the distance between the lowest blade tip and the bottom surface of the disc cavity is L1; 0.25≤L1 / L2≤0.75.

[0013] As set up above, since 0.25≤L1 / L2≤0.75, the heating area on the side surface of the disc cavity of the side wall of the disc body corresponding to the heating element is heated by the heating element, and this area is closer to the turbulence area of ​​the blade, and the turbulence of the blade (at least the turbulence generated by the blade with the lowest blade tip) acts more effectively on the heating area, the stirring effect of the blade is good, and the fluidity of the food is better. Therefore, it can better prevent the side surface of the disc cavity from being stuck to food and being burned, and correspondingly, it can prevent the bottom surface of the disc cavity from being stuck to food and being burned.

[0014] In some embodiments, L1 and L2 satisfy at least one of the following conditions: a) 0.3≤L1 / L2≤0.6; b) 5mm≤L1≤25mm; c) 6mm≤L2≤60mm.

[0015] As set above, since L1 and L2 meet at least one of the following conditions: a) 0.3≤L1 / L2≤0.6; b) 5mm≤L1≤25mm; c) 6mm≤L2≤60mm, the food has better fluidity and can prevent the side of the dish cavity from getting stuck to the food and being burned.

[0016] In some embodiments, the side wall of the tray body includes a side wall top portion relative to the bottom wall of the tray body, and the heating element is located at the side wall top portion.

[0017] In this arrangement, because the heating element is located at the top of the side wall and circumferentially arranged around the side wall of the dish, the heating element is relatively far from the bottom wall of the dish. Heat generated by the heating element is transferred to the bottom wall of the dish through the side wall of the dish. The bottom surface of the dish cavity serves as the inner surface of the bottom wall of the dish. This ensures uniform heating of the bottom wall of the dish, making the bottom surface of the dish cavity less likely to burn. Furthermore, when the heating element is further away from the bottom surface of the dish cavity, the food in the dish cavity is heated by the heated water, further preventing the bottom surface of the dish cavity from burning.

[0018] In some embodiments, a positioning portion is provided at a top end of the tray sidewall relative to the tray bottom wall, the positioning portion wraps around the tray sidewall and is folded back from the top end toward the tray bottom wall, so that the positioning portion and the tray sidewall form a barb. The heating element is welded into the barb.

[0019] As described above, since the heating element is located within the barb, during the welding process, the positioning portion and the barb formed by the top of the side wall of the disk body can be used to position the heating element, making positioning easy and facilitating welding of the heating element. In addition, during the welding process, the barb formed by the positioning portion and the top of the side wall of the disk body prevents the welding liquid from flowing out, thereby ensuring the welding effect and preventing the welding liquid from flowing into the disk body cavity.

[0020] In some embodiments, the heating element contacts the side wall of the disk to form a contact surface; along the axial direction of the blade shaft, the lowest blade tip is located between the top edge and the bottom edge of the contact surface.

[0021] As set up above, since the lowest blade tip is located between the top edge and the bottom edge of the contact surface, the heating area on the side of the dish cavity corresponding to the heating element is more within the turbulence area of ​​the blade (especially the turbulence area of ​​the blade with the lowest blade tip). Therefore, the turbulence generated by the stirring of the blade has a good stirring effect on the food, making the food more fluid and preventing the side of the dish cavity from getting stuck to the food and being burned.

[0022] In some embodiments, all blade tips of the plurality of blades are located in the disc cavity, and the highest blade tip is lower than or flush with the heating element.

[0023] As set up above, the heating element is far away from the bottom surface of the dish cavity. In addition to the aforementioned P1 / P2 ratio that can prevent the side of the dish cavity from being burned, on the one hand, the heat generated by the heating element is transferred to the bottom wall of the dish body through the side wall of the dish body, so that the bottom wall of the dish body is heated evenly, preventing the bottom surface of the dish cavity from being burned. On the other hand, the heat of the heating element heats the food by heating the water in the dish cavity, which can also prevent the bottom surface of the dish cavity from being burned.

[0024] In a second aspect, the present application discloses a food processor. The food processor comprises a drive assembly, a blending cup, and any of the aforementioned heating plate assemblies, wherein the heating plate assembly and the blending cup define a food blending chamber; the food blending chamber includes the plate cavity; and the drive assembly drives the blade assembly to rotate within the food blending chamber.

[0025] As configured above, the food processor at least has the beneficial effects of the heating plate assembly, which will not be described in detail. BRIEF DESCRIPTION OF THE DRAWINGS

The plate body side wall 12 and the plate body bottom wall 11 form a plate body cavity 13. The plate body cavity 13 includes a plate body cavity bottom surface 131 and a plate body cavity side surface 132 surrounding the plate body cavity bottom surface 131. That is, the plate body cavity bottom surface 131 is the inner surface of the plate body bottom wall 11. The plate body cavity side surface 132 is the inner surface of the plate body side wall 12. The structure of the plate body 1 is not limited and can be as follows Figure 6 and Figure 4 The schematic diagram includes an inner plate 141 and a heat conducting plate 142.

The inner plate 141 is made of food-grade stainless steel. The heat conducting plate 142 can be an aluminum plate that can conduct heat. The plate 1 can also be made of Figure 8 Combined with Figure 7 The single-layer structure shown.

[0040] Continue to see Figures 3 to 8 , Figure 3 The blender jar assembly shown includes Figure 4 The heating plate assembly shown. Figure 5 yes Figure 4 A top view of the assembled state; Figure 6 It is along Figure 5 Cross-sectional view of line AA; Figure 8 yes Figure 7 An enlarged view of part A in the figure. The heating element 2 is arranged around the circumference of the dish side wall 12 and is located outside the dish cavity 13. The circumferential arrangement is not limited to the heating element 2 being arranged on the outer surface of the side wall of the dish side wall 12. In some embodiments, the heating element 2 can also be arranged inside the dish side wall 12. The heating element 2 is not limited to a heating tube. There can also be multiple heating elements 2, which are distributed at intervals in the circumference of the dish side wall 12. In short, the heating element 2 can generate heat to heat the dish 1, and ultimately, heat the food in the food stirring cavity surrounded by the dish 1 and the stirring cup 20.

[0041] Continue to see Figure 4 、 Figures 6 to 8, the knife assembly 5 includes a knife shaft 52 rotatably assembled with the bottom wall 11 of the disk body and a plurality of knife blades 53 assembled with the knife shaft 52. In the embodiment of the present application, the knife assembly 5 includes a bearing seat 51, and the bearing seat 51 can be welded to the bottom wall 11 of the disk body. The knife shaft 52 is assembled with the bearing seat 51 through bearings and other components, thereby realizing the rotational assembly of the knife shaft 52 and the bottom wall 11 of the disk body. In the present application, the knife blade 53 includes a first knife blade 531 and a second knife blade 532. The first knife blade 531 and the second knife blade 532 each have two blades, so that Figure 4 and Figure 5 As shown, the blade assembly 5 is a four-blade blade. The number of blades is not limited thereto, and in some cases, it can also be two blades, three blades, etc. In this embodiment, the first blade 531 has the lowest blade tip 5311, and the second blade 532 has the highest blade tip 5321. Figure 3 and Figure 6 It is shown that the lowest tip 5311 is located in the disc cavity 13. Figure 8 Combined with Figure 7 It is shown that the highest knife tip 5321 and the lowest knife tip 5311 are both located in the disc cavity 13.

[0042] See also Figure 3 、 Figure 7 and Figure 8 , along the axial direction of the blade shaft 52, the distance between the bottom of the heating element 2 and the bottom surface 131 of the disc cavity is H1. Among the blade tips of the multiple blades 53, the distance between the highest blade tip 5321 and the bottom surface 131 of the disc cavity is H2, 0.05≤H1 / H2≤2. Some ratios of H1 / H2 are as follows: 0.05, 0.08, 0.1, 0.12, 0.15, 0.18, 0.2, 0.23, 0.25, 0.28, 0.3, 0.33, 0.35, 0.38, 0.4, 0.43, 0.45, 0.48, 0.5, 0.53, 0.55, 0.58, 0.6, 0.63, 0.65, 0.68, 0.7, 0.72, 0.75, 0.8, 0.82, 0.85, 0.9, 0.93, 0.95, 1, 1.05, 1.08, 1.1, 1.15, 1.18, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45, 1.5, 1.55, 1.6, 1.65, 1.7, 1.75, 1.8, 1.85, 1.9, or 2. Figure 11 This is a chart generated based on the following table.

[0043] H1 / H2 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 Number of rice 13 11 8 5 3 4 3 2 H1 / H2 0.5 0.55 0.6 0.65 0.7 0.75 0.8 0.85 0.9 Number of rice 0 3 5 6 6 9 12 15 15

[0044] Based on the common phenomenon of sticking to the bottom, the anti-sticking test standard is divided into 7 levels. The sticking of the common ingredients carrot rice and pumpkin rice after cooking for 5 consecutive times is used as the standard. The specific results are as follows:

[0045] Level 1: No sticking to the bottom or layering, no sticking to rice grains;

[0046] Level 2: Residual rice grains ≤5;

[0047] Level 3: 5<residual rice grains≤15;

[0048] Level 4: Residual rice grains>15;

[0049] Level 5: Slightly smudged bottom;

[0050] Level 6: Severely blurred;

[0051] Level 7: The fuse is blown.

[0052] The anti-sticking level of common food processors on the market is basically at level 4-5, which makes it difficult to clean and affects the user experience.

[0053] As set up above, due to the said 0.05≤H1 / H2≤2, the heating area corresponding to the heating element 2 on the side surface 132 of the dish cavity is within the turbulence area of ​​the blade. By controlling the distance between the blade and the heating element 2, the turbulence generated by the blade has a good stirring effect on the food, so that the fluidity of the food is good, and ultimately, the food is prevented from sticking to the side surface 132 of the dish cavity and burning; furthermore, the heating element 2 is arranged circumferentially around the side wall 12 of the dish body, and the heating element 2 heats the side wall 12 of the dish body, and the heat is then transferred to the bottom wall 11 of the dish body through the side wall 12 of the dish body. The bottom wall 11 of the dish body can be heated evenly, and the turbulence with the blade has a good stirring effect on the food, so that the fluidity of the food is good, and the bottom surface 131 of the dish cavity will not stick to the food and burn. In summary, the above setting can not only prevent the side wall of the dish body from being burned, but also prevent the bottom wall of the dish body (bottom of the dish) from being burned. For example, food accumulates on the bottom of the dish (bottom wall of the dish body) due to poor fluidity, causing the bottom of the dish to be burned. Of course, both the disc cavity side surface 132 and the disc cavity bottom surface 131 are prevented from being burnt, which can improve the heating efficiency of the heating element 2.

[0054] See also Figure 3 、 Figure 6 and Figure 11 , the tips of some blades (the first blade 531 in this embodiment) are located inside the disc cavity 13, and the highest blade tip 5321 (the second blade 532 in this embodiment) is located outside the disc cavity 13; 0.05≤H1 / H2≤0.9. Figure 11 As well as the above table, preferably, 0.2≤H1 / H2≤0.75.

[0055] In the above arrangement, since 0.2≤H1 / H2≤0.75, the heating area corresponding to the heating element 2 on the side surface 132 of the dish cavity is more within the turbulent flow area of ​​the blade. The turbulent flow generated by the blade has a better stirring effect on the food, making the food more fluid, thereby preventing the side surface of the dish cavity from getting stuck to the food and burning it. Of course, as mentioned above, the dish side wall 12 is heated and then transfers heat to the dish bottom wall 11, so that the dish bottom wall 11 is evenly heated. Combined with the turbulent flow of the blade, the dish cavity bottom surface 131 will not get stuck to the food and burn it. In summary, the above arrangement can better prevent the dish body 1 from getting burned.

[0056] See also Figure 7 and Figure 8 In some embodiments, the tips of all blades are located in the disc cavity 13, and 1≤H1 / H2≤2.

[0057] As described above, for 1≤H1 / H2≤2, the highest blade tip 5321 is located within the dish cavity 13, the heating element 2 is relatively high, and the majority of the food is located within the dish cavity 13. The food is also heated by heating the liquid within the dish cavity 13, ensuring even heating of the food and preventing the dish cavity bottom 131 from burning. When H1 / H2>2, the higher position of the heating element 2 results in a higher dish sidewall 12. This, firstly, increases costs; secondly, makes installation of the heating element 2 more difficult; and thirdly, when the user is blending a small volume of food, a high position of the heating element 2 can cause the heating element 2 to dry out.

[0058] See also Figure 6 and Figure 3 The heating element 2 contacts 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 and bottom edges of the contact surface. The lowest blade tip 5311 is located between the top and bottom edges of the contact surface, including the following: 1) Figure 6 As shown, the top edge of the contact surface is F, the bottom edge is f, the lowest blade tip 5311 is located between F and f, the blade tip of the first blade 531 (that is, the lowest blade tip 5311) is located between the top edge F and the bottom edge f of the contact surface, and the blade tip of the second blade 532 is located outside the disc body cavity 13; 2) all the blade tips are located inside the disc body cavity 13, and only the lowest blade tip 5311 is located between the top edge and the bottom edge of the contact surface; 3) it is also possible that all the blade tips are the lowest blade tips, and are all located between the top edge F and the bottom edge f of the contact surface.

[0059] As described above, the lowest blade tip 5311 is located between the top and bottom edges of the contact surface, and the heating area on the side surface 132 of the disc cavity corresponding to the heating element 2 is more within the turbulent flow area of ​​the blade (especially the turbulent flow area of ​​the blade with the lowest blade tip). As a result, the turbulent flow generated by the stirring of the blade has a good stirring effect on the food, making the food more fluid and better able to prevent the side surface 132 of the disc cavity from being stained and burned. Technicians will understand that the lowest blade tip 5311 being located between the top and bottom edges of the contact surface also has the aforementioned beneficial effects. When combined with other embodiments described in this application, such as 0.05≤H1 / H2≤2, it can more effectively prevent the side surface 132 of the disc cavity and the bottom surface 131 of the disc cavity from being burned.

[0060] See also Figure 7 and Figure 8 Furthermore, when 1≤H1 / H2≤2, the highest blade tip 5321 is lower than the heating element 2, or 0mm≤H1-H2≤35mm.

[0061] As configured above, if one of the above conditions is met, the food can have better fluidity and avoid the dish cavity side surface 132 and the dish cavity bottom surface 131 from being stained with food and being burned.

[0062] Continue to see Figure 6 and Figure 8 The disc cavity 13 includes a disc cavity side surface 132. The disc cavity side surface 132 is inclined toward the outside of the disc cavity bottom surface 131. This inclination can be like Figure 3 and Figure 6 Like this, the whole is tilted. You can also do it like Figure 8 Combined with Figure 7 In this way, the lower part of the disc cavity side surface 132 is inclined outward, and the upper part is perpendicular to the disc cavity bottom surface 131. Of course, the outward inclination is not limited to this, as long as the disc side wall 12 is tilted upward relative to the disc cavity bottom surface 131 and is located outside the disc cavity bottom surface 131. At least part of the multiple blades are located in the disc cavity 13, see Figure 6 In this embodiment, the first blade 531 extends into the disc cavity 13 and is entirely located in the disc cavity 13, while the second blade 532 extends out of the disc cavity 13. In other embodiments, the first blade 531 including a portion of the blade tip is located in the disc cavity 13, while the other portion is located outside the disc cavity 13. Figure 8In some other embodiments, all blades (such as the first blade 531 and the second blade 532 of the present application) may be located within the disc cavity 13. Along the radial direction of the blade axis 52, the distance between the lowest blade tip 5311 of the plurality of blades 53 and the disc cavity side surface 132 is P1. The width of the projection of the disc cavity side surface 132 on the radial plane of the blade axis 52 is P2, where 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.

[0063] See also Figure 9 Combined with the following table, Figure 9 The chart is generated based on the following table:

[0064] P1 / P2 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 Number of rice 6 4 2 0 0 3 5 7 P1 / P2 0.5 0.55 0.6 0.65 0.7 Number of rice 11 13 13 18 25

[0065] From the above chart and table, we can see that when 0.1≤P1 / P2≤0.25, the number of rice sticking shows a downward trend. When the ratio of P1 / P2 is greater than 0.3, the number of rice sticking shows an upward trend. Furthermore, when the ratio is 0.15≤P1 / P2≤0.4, the number of rice sticking is less than or equal to 5, and the anti-sticking effect is optimal, reaching a level 2 anti-sticking effect. When the ratio of P1 / P2 is 0.45, the number of rice sticking is 7; at 0.5, the number of rice sticking is 11, when the ratio is 0.55, the number of rice sticking is 13, when the ratio is 0.6, the number of rice sticking is 13, when the ratio is 0.65, the number of rice sticking is 18, and when the ratio is 0.7, the number of rice sticking is 25. In summary, 0.1≤P1 / P2≤0.6.

[0066] As set up above, since 0.1≤P1 / P2≤0.6, the distance between the side surface 132 of the disc cavity and the blade will not be too far, so that the turbulence of the blade (at least the turbulence generated by the blade with the lowest blade tip 5311) can more effectively act on the heating area corresponding to the side surface 132 of the disc cavity and the heating element 2, which has a good stirring effect on the food and makes the food fluidity good, thereby preventing the food from sticking to the side surface 132 of the disc cavity and getting burnt. In addition, the heating element 2 is arranged circumferentially around the side wall 12 of the disc body, first heating the side wall 12 of the disc body, and the heat is transferred to the bottom wall 11 of the disc body through the side wall 12 of the disc body. The bottom wall 11 of the disc body is evenly heated, and the turbulence generated by the blade makes the food fluidity good, and the bottom surface 131 of the disc cavity will not stick to the food and get burnt. In summary, the above setting can avoid the problem of food poor in fluidity and accumulation at the bottom of the disc and getting burnt, thereby improving the user experience. Of course, in the above embodiment, if the heating element 2 is far from the bottom wall 11 of the dish, as in the aforementioned 1 ≤ H1 / H2 ≤ 2, and the food sinks to the lower part of the dish cavity 13 due to gravity, the heating element 2 first heats the water in the dish cavity 13, which then heats the food. Combined with the turbulence generated by the blades, this also helps prevent the dish 1 from burning. It will be appreciated by those skilled in the art that the aforementioned 0.1 ≤ P1 / P2 ≤ 0.6 can be combined with H1 / H2 or can be independent of H1 / H2.

[0067] See also Figure 6 and Figure 8 In some embodiments, 3mm≤P1≤25mm, for example, 3mm, 5mm, 8mm, 10mm, 12mm, 15mm, 17mm, 20mm, 22mm, 24mm or 25mm; 5mm≤P2≤60mm, for example, 5mm, 7mm, 9mm, 10mm, 15mm, 18mm, 20mm, 23mm, 25mm, 28mm, 30mm, 33mm, 35mm, 37mm, 40mm, 45mm, 48mm, 50mm, 53mm, 55mm, 57mm or 60mm. Technicians can understand that it is sufficient that at least one of 3mm≤P1≤25mm and 5mm≤P2≤60mm is satisfied. In the example Figure 6 and Figure 8 Combined with Figure 7 In the case of the disc cavity side surface 132 shown, 3mm≤P1≤25mm, and 5mm≤P2≤30mm. If the width of the disc cavity bottom surface 131 is narrowed, the disc cavity side surface 132 will be longer (for example, the upper bottom surface of the frustum can be considered as the smaller disc cavity bottom surface 131), 3mm≤P1≤25mm; 5mm≤P2≤60mm.

[0068] As set above, since 3mm≤P1≤25mm; and / or, 5mm≤P2≤60mm, the blade has a good stirring effect, and the turbulence generated by the blade makes the food more fluid, avoiding the side surface 132 and the bottom surface 131 of the disc cavity from being burned.

[0069] See also Figure 6 and Figure 4 , the disc cavity side surface 132 is inclined outwardly toward the disc cavity bottom surface 131 so that the disc cavity 13 gradually increases in size away from the disc bottom wall 11, thereby achieving the outer inclination. Figure 6 As shown, the disc cavity side surface 132 is a rotational curved surface formed by an arc (a segment of a circle or a segment of an ellipse) rotating around the rotation centerline of the blade shaft 52. In other embodiments, the outer inclined surface can also be a rotational curved surface formed by a straight line inclined to the rotation centerline of the blade shaft 52 rotating around the rotation centerline, that is, the side surface of a frustum.

[0070] In addition, the method of gradually increasing the size of the tray cavity 13 in a direction away from the tray bottom wall 11 also includes the following embodiments: Figure 8 Combined with Figure 7 , the disk 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 knife shaft 52. The bottom edge of the connecting surface 1321 is connected to the disk cavity bottom surface 131, and the connecting surface 1321 is inclined outward from the disk cavity bottom surface 131 so that the disk cavity 13 gradually increases in the direction away from the disk bottom wall 11 to achieve the outer inclination. Here, the shape of the connecting surface 1321 is a rotating curved surface formed by a circular arc line rotating around the rotation center line, or it can be a rotating curved surface formed by a straight line inclined to the rotation center line rotating around the rotation center line (that is, the side of a cone).

[0071] As described above, since the disc cavity side surface 132 is tilted outward as a whole, so that the disc cavity 13 gradually increases in the direction away from the disc bottom wall 11, or the connecting surface 1321 of the disc cavity side surface 132 is tilted outward so that the disc cavity 13 gradually increases in the direction away from the disc bottom wall 11, on the one hand, the outward tilt of the disc cavity side surface 132 can better utilize the turbulence generated by the blade, and the turbulence effect is good, so that the food can form an effective circulation path in the disc cavity 13, which helps to bring large pieces of food to the vicinity of the blade 53 for cutting, and improves the fluidity of the food. To prevent food from getting stuck on the sides 132 of the food tray cavity and getting burned, on the other hand, when the volume of the tray cavity 13 is equal, the outward inclination of the sides of the tray cavity can make the bottom surface 131 of the tray cavity smaller. The turbulence can maximize the fluidity of the food, allowing the liquid and solid mixture to circulate more smoothly in the tray cavity 13, making the food fluidity good, and preventing food from getting stuck on the sides 132 of the tray cavity and getting burned. Because the bottom surface 131 of the tray cavity heats the food through heat transfer from the sides 132 of the tray cavity, combined with the turbulence of the blade, the above arrangement can also prevent the bottom surface 131 of the tray cavity from getting burned. In addition, the intersection of the curved surface and the bottom surface 131 of the tray cavity does not produce a dead angle, making it easier to clean the tray body 1 (i.e., the heating tray assembly 10). Technicians can understand that the disc cavity 13 gradually increases in size in the direction away from the disc bottom wall 11 to achieve the outward inclination, or the disc cavity side 132 including the connecting surface 1321 and the cylindrical surface 1322 itself also has the aforementioned function, which can be combined with other embodiments described in this application such as 0.05≤H1 / H2≤2 to more effectively prevent the disc cavity side 132 and the disc cavity bottom 131 from being burned.

[0072] See also Figure 6 and Figure 8 The disc cavity side surface 132 includes a bottom edge connected to the disc cavity bottom surface 131 and a top edge relative to the bottom edge; the angle between the tangent plane passing through the top edge and the bottom edge and the disc cavity bottom surface 131 is α, 90 degrees ≤ α ≤ 170 degrees, for example, 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 Figure 6 and Figure 8 The shape of the disc cavity side 132 is shown. Figure 10 , Figure 10 This is a chart based on the following table.

[0073] α 90 95 100 105 110 115 120 125 130 Number of rice 11 8 8 6 2 0 3 5 5 α 135 140 145 150 155 160 165 170 Number of rice 8 7 6 8 9 12 15 14

[0074] exist Figure 10In the figure, when the angle α is around 105 degrees to 130 degrees, the number of particles sticking to the rice is within 5, and when the angle α exceeds 130 degrees, the number of particles sticking to the rice exceeds 5.

[0075] As described above, when the angle is 90 degrees ≤ α ≤ 170 degrees, the turbulence generated by the blades provides a good stirring effect, improves food fluidity, and prevents food from getting stuck on the sides 132 and bottom 131 of the dish cavity and burning. It will be appreciated by those skilled in the art that 90 degrees ≤ α ≤ 170 degrees alone also has the aforementioned effect, and when combined with other embodiments described herein, such as 0.05 ≤ H1 / H2 ≤ 2, it can more effectively prevent food from getting stuck on the sides 132 and bottom 131 of the dish cavity.

[0076] See also Figure 6 , along the axial direction of the blade shaft 52, the distance between the top of the heating element 2 and the bottom surface 131 of the disc cavity is L2; ​​the distance between the lowest blade tip 5311 and the bottom surface 131 of the disc cavity is L1; 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 here that, Figure 6 In the figure, along the axial direction of the blade shaft 52, the lowest blade tip 5311 is located between the top and bottom edges of the contact surface formed by the heating element 2 and the side wall 12 of the disk body. However, when 0.25≤L1 / L2≤0.75, the lowest blade tip 5311 may also be lower than the bottom edge of the contact surface or other situations.

[0077] As set above, since 0.25≤L1 / L2≤0.75, the heating area corresponding to the disc cavity side surface 132 of the disc side wall 12 and the heating element 2 is heated by the heating element 2, and this area is close to the turbulence area of ​​the blade, and the turbulence of the blade (at least the turbulence generated by the blade with the lowest blade tip) acts more effectively on the heating area, and the stirring effect of the blade is good, which makes the food more fluid. Therefore, it can better prevent the disc cavity side surface 132 from being stained with food and being burned, and correspondingly, it can prevent the disc cavity bottom surface 131 from being stained with food and being burned.

[0078] Technicians can understand that 0.25≤L1 / L2≤0.75 itself also has the aforementioned effect, and combined with other embodiments described in this application such as 0.05≤H1 / H2≤2, it can more effectively prevent the disc cavity side surface 132 and the disc cavity bottom surface 131 from being burned.

[0079] In some embodiments, L1 and L2 satisfy at least one of the following conditions:

[0080] 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;

[0081] 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;

[0082] 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.

[0083] As configured above, since L1 and L2 satisfy at least one of a) 0.3≤L1 / L2≤0.6; b) 5mm≤L1≤25mm; c) 6mm≤L2≤60mm, the food has better fluidity and can better prevent the dish cavity side surface 132 and the dish cavity bottom surface 131 from being stained and burned.

[0084] See also Figure 6 and Figure 8 Combined with Figure 7 The disk side wall 12 includes a side wall top 121 relative to the disk bottom wall 11 , and the heating element 2 is located at the side wall top 121 .

[0085] As described above, since the heating element 2 is located at the top end 121 of the side wall and is arranged circumferentially around the side wall 12 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 bottom surface 131 of the disc body cavity is the inner surface of the bottom wall 11 of the disc body. In this way, the bottom wall 11 of the disc body is heated evenly and the bottom surface 131 of the disc body cavity is less likely to be burned. In addition, when the heating element 2 is as Figure 8 Combined with Figure 7 In this way, when the food is further away from the bottom surface 131 of the dish cavity, the food in the dish cavity 13 can be heated by the heated water, which can better prevent the bottom surface 131 of the dish cavity from being burned.

[0086] See also Figure 6 and Figure 8 Combined with Figure 7 The disc cavity side surface 132 is the surface of the disc side wall 12. Figure 4In the embodiment, the dish cavity side surface 132 is the inner surface of the dish side wall 12, the dish cavity bottom surface 131 is the surface of the dish bottom wall 11, and the dish cavity side surface 132 and the dish cavity bottom surface 131 are in direct contact with food.

[0087] As configured above, the plate cavity side surface 132 and the plate cavity bottom surface 131 are in direct contact with food, and the plate body 1 does not include a coating. Therefore, the heating plate assembly 10 of the present application can not only avoid sticking to the bottom, but also prevent the coating from falling off, thereby improving the user experience.

[0088] See also Figure 4 and Figure 6 The tray side wall 12 is provided with a positioning portion 122 at the top end relative to the tray bottom wall 11. The positioning portion 122 is bent back from the top end toward the tray bottom wall 11 so that the positioning portion 122 and the tray side wall 12 form a barb 110. The heating element 2 is welded into the barb 110. The positioning portion 122 is used to position the heating element 2. The structure is not limited, as long as it can form a barb 110 to achieve assembly of the heating element 2. Figure 4 The positioning portion 122 is shown as a circle around the side wall 12 of the disk. Figure 4 and Figure 6 In the embodiment, the positioning portion 122 is provided on the heat conducting plate 118. Of course, the component of the plate body 1 where the positioning portion 122 is provided is determined according to the structure of the plate body 1. Figure 4 and Figure 6 In some embodiments, the heating element 2 is welded to the side wall 12 of the tray. There is no limitation on how to achieve the welding, as long as the heating element 2 is finally located in the barb 110 .

[0089] As described above, since the heating element 2 is located within the barb 110, during the welding process, the positioning portion 122 and the barb 110 formed by the top of the plate side wall 12 can be used to position the heating element 2, making positioning easy and facilitating welding of the heating element 2. Furthermore, during the welding process, the positioning portion 122 and the top of the plate side wall 12 form the barb 110 to prevent the welding liquid from flowing out, thereby ensuring the welding effect and preventing the welding liquid from flowing into the plate cavity 13. If the welding liquid flows into the plate cavity 13, it needs to be cleaned up, which is costly and has a high defect rate.

[0090] In the above embodiment, see Figure 8 and Figure 7 All blade tips of the plurality of blades are located within the disc cavity 13, and the highest blade tip is lower than or flush with the heating element 2. Of course, in some embodiments, the highest blade tip 5321 may also be flush with the bottom of the heating element 2, and H1 and H2 may not satisfy the above ratio.

[0091] As described above, the heating element 2 is far away from the bottom surface 131 of the dish cavity. In addition to the aforementioned P1 / P2 ratio that can prevent the side surface 132 of the dish cavity from being burned, on the one hand, the heat generated by the heating element 2 is transferred to the bottom wall 11 of the dish body through the side wall 12 of the dish body, so that the bottom wall 11 of the dish body is heated evenly, preventing the bottom surface 131 of the dish cavity from being burned. On the other hand, the heat of the heating element 2 heats the food by heating the water in the dish cavity 13, which can also prevent the bottom surface 131 of the dish cavity from being burned.

[0092] See also Figure 1 Combined with Figure 2 、 Figure 3 and Figure 7 In the second aspect, the present application discloses a food processor. The food processor includes a drive assembly, a blending cup 20 and any one of the aforementioned heating plate assemblies 10. In this embodiment, the drive assembly is disposed in the main unit 200. The food processor also includes a cup cover 30, a cup holder 40, a bottom cover 50, a coupler 60 and a handle 70. The plate body 1 of the heating plate assembly 10 and the blending cup 20 form a food stirring chamber. The food stirring chamber includes the plate body cavity 13. The food stirring chamber has a minimum water level, Figure 3 and Figure 7 The distance between the lowest water level and the bottom surface 131 of the dish cavity is H3. The highest blade tip 5321 is lower than or flush with the lowest water level. The driving assembly drives the blade assembly 5 to rotate in the food stirring cavity.

[0093] As configured above, the food processor at least has the beneficial effects of the heating plate assembly 10, which will not be described in detail.

[0094] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
