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] A food processor includes a cooking cup and a heating plate assembly. The heating plate assembly is typically located at the bottom of the cooking cup, forming a food processing space with the cooking cup. The heating plate assembly heats the food in the food processing space.

[0003] The existing heating plate includes a flat plate body and a heating element arranged on the plate body. The plate body serves as the bottom of the cooking cup and is used to hold food. In this way, the bottom of the food is easily burnt during the heating process of the heating element. Utility Model Content

[0004] The purpose of the present application is to disclose a heating plate assembly and a food processor. The heating plate assembly is not easy to get stuck on the bottom.

[0005] In a first aspect, the present application discloses a heating plate assembly. The heating plate assembly includes a plate body and a heating element, wherein the plate body includes a plate bottom and a plate side wall surrounding the plate bottom to enclose a stirring space. The knife assembly is arranged at the plate bottom and includes a blade. Along the radial direction of the plate bottom, the tip of the blade is located between the edge of the plate bottom and the plate side wall. The plate side wall includes a turbulence area formed corresponding to the rotation of the blade; the heating element is arranged on the plate side wall to form a contact surface with the plate side wall, and the contact surface at least partially overlaps with the turbulence area.

[0006] As described above, since the contact surface and the turbulence area at least partially overlap, and the heating element is arranged on the side wall of the dish, and the tip of the knife is located between the edge of the bottom of the dish and the side wall of the dish, the fluidity of the food can be maximized, and the food heated by the heating element is more easily washed away by the turbulence. As little food as possible stays in the heating area of ​​the heating element, thereby preventing the side wall and the bottom of the dish from being burned. In addition, when the heating element is arranged on the side wall of the dish, after the side wall of the dish is heated, the heat is transferred to the bottom of the dish to heat the food on the bottom of the dish. The bottom of the dish is heated by the heat transfer, and the heat is evenly heated and is not directly heated. Combined with the turbulence, the side wall of the dish will not be burned, and the bottom of the dish will not be burned (i.e., the bottom will be burnt). Because the bottom of the dish and the side wall of the dish are not easy to burn, the heating effect is good. For example, a higher power heating can be used, or the heating time is relatively long, making the food taste better.

[0007] In some embodiments, the contact surface is a curved surface.

[0008] As described above, since the contact surface is a curved surface with a large area, combined with the aforementioned features, it is possible to better avoid heat concentration that causes the side wall of the disk to be burned.

[0009] In some embodiments, the curved surface is an arc-shaped surface.

[0010] As set up above, the curved surface is an arc-shaped surface. In this way, under the premise that the side wall of the disk is not easily burned, it is also convenient to assemble the disk body and the heating element, such as welding, etc.

[0011] In some embodiments, the sidewall of the disk is arc-shaped, and the corresponding radius is R, 30 mm ≤ R ≤ 65 mm.

[0012] As set up above, since 30mm≤R≤65mm, not only does it satisfy the aforementioned requirement that the side wall of the disk is not easily burned, but also, when the disk body includes an inner disk body and an outer disk body covering the inner disk body, it is convenient to assemble the inner disk body and the outer disk body and the assembly quality is good. For example, when welding is used between the inner disk body and the outer disk body, there will be no cold welds.

[0013] In some embodiments, the tray includes an inner tray and an outer tray covering the inner tray.

[0014] In some embodiments, the tray sidewall and the tray bottom form an obtuse angle.

[0015] As set up above, since the side wall of the plate and the bottom of the plate are at an obtuse angle, the side wall of the plate expands outward. In this way, when the volume of the stirring space is equal, the bottom of the plate is smaller, and the turbulence can maximize the fluidity of the food. Thus, the turbulence effect of the knife assembly is better. Ultimately, the turbulence can more easily wash away the food on the temperature measuring head. Thus, the temperature measured by the temperature measuring assembly is more accurate, which can avoid misjudgment caused by inaccurate temperature, and further avoid problems such as dry burning of the heating plate assembly.

[0016] In some embodiments, the disk body includes an inner disk body and an outer disk body covering the inner disk body, wherein the edge of the outer disk body is folded back to form a receiving groove, and the edge of the heating element includes a corner, and the corner is located in the receiving groove.

[0017] As described above, with the corner located in the receiving groove, the outer disc and the inner disc can be positioned for assembly, making assembly of the outer disc and the inner disc easier. When the outer disc and the inner disc are welded, the receiving groove can also prevent the solder from flowing out during the welding process.

[0018] In some embodiments, the edge of the tray is bent to form a positioning portion for assembling with the cup holder.

[0019] As configured above, the positioning portion is used for positioning, thereby facilitating the assembly of the heating plate assembly to the cup holder.

[0020] In some embodiments, the heating element includes an outer side surface connected to the contact surface, the outer side surface is formed by connecting a plurality of side surfaces, and corners formed by adjacent side surfaces all protrude outward.

[0021] As described above, since the outer side surface connected to the contact surface includes multiple side surfaces, the corners formed by adjacent side surfaces protrude outwards. In this way, the heating element does not have an undercut structure, etc., which facilitates demoulding.

[0022] In some embodiments, the knife assembly includes a knife shaft for assembling the blade; and the heating plate assembly satisfies at least one of the following relationships:

[0023] a) The width of the orthographic projection of the pan sidewalls on a horizontal plane is C, and the width between the pan sidewalls is L, where 0≤C / L≤1 / 2. As described above, since 0≤C / L≤1 / 2, the space enclosed by the pan sidewalls and the pan bottom is kept small, facilitating airflow disturbance when the heating pan assembly includes a knife assembly. When the pan sidewalls are curved, the curvature is maintained, resulting in a better airflow disturbance effect, thereby better preventing food from sticking to the airflow disturbance area and preventing the pan sidewalls from burning.

[0024] b) Along the axial direction of the blade shaft, the minimum distance from the blade to the bottom of the disk is a, the depth of the disk body is A, and 1 / 4≤a / A≤3 / 4; as set above, 1 / 4≤a / A≤3 / 4 can ensure that the turbulence area has sufficient width, and thus, the area is large, and heat is not easily concentrated to cause the side wall of the disk to be burned.

[0025] c) Along the axial direction of the blade shaft, the distance between the bottom surface of the heating element and the bottom of the plate is H, 0<H≤15mm; as set above, 0<H≤15mm ensures that the heating element is spaced from the bottom of the plate, and thus, the bottom of the plate is not directly heated, avoiding the bottom of the plate from being burned.

[0026] d) Along the radial direction of the bottom of the dish, the distance P between the tip of the blade and the sidewall of the dish is 1.5 mm ≤ P ≤ 10 mm. This arrangement prevents large particles of food from becoming stuck between the blade tip and the sidewall, resulting in a more delicate blending of the food. Furthermore, the food is more delicate and flows more easily, resulting in a better flow disturbance. Furthermore, there is sufficient distance to prevent the blade tip from scratching the sidewall of the dish.

[0027] In a second aspect, embodiments of the present application disclose a food processor comprising any of the aforementioned heating plate assemblies, a drive device, and a blending cup, wherein the heating plate assembly comprises a blade assembly, and the drive device drives the blade assembly to rotate within the blending cup.

[0040] See also Figure 5 and Figure 6 Combined with Figure 3 and Figure 4 In the first aspect, the present application discloses a heating plate assembly 10. The heating plate assembly 10 includes a plate body 1, a knife assembly 2 and a heating element 4. In an embodiment of the present application, the heating plate assembly 10 also includes a temperature measuring assembly 3, a temperature controller 5 and a sealing ring 6. In an embodiment of the present application, the plate body 1 includes an inner plate body 119 and an outer plate body 118 wrapped around the inner plate body 119. The material of the inner plate body 119 is, for example, stainless steel. The material of the outer plate body 118 is stainless steel. In other embodiments, the plate body 1 can also be a single component. Regardless of how the plate body 1 is constructed. The plate body 1 includes a plate bottom 11 and a plate side wall 12 surrounding the plate bottom 11. The plate bottom 11 includes a portion of the inner plate body 119 and a portion of the outer plate body 118. Correspondingly, the plate side wall 12 includes a portion of the inner plate body 119 and a portion of the outer plate body 118. The plate bottom 11 and the plate side wall 12 enclose a stirring space.

[0041] See also Figure 6 Combined with Figure 4 、 Figure 5 and Figure 7The knife assembly 2 is arranged on the bottom 11 of the plate and includes a blade 21. Figure 5 , taking the horizontal plane where the blade 21 is assembled on the blade shaft 22 as a reference, the blade 21 includes a first blade 211 with the tip located below the horizontal plane and a second blade 212 with the tip located above the horizontal plane. Technicians can understand that the blade assembly 2 can also be a two-leaf blade, a three-leaf blade, etc. In an embodiment of the present application, the blade assembly 2 is connected to the drive device through a clutch, so that the blade shaft 22 of the blade assembly 2 is rotatably connected to the disk bottom 11 of the disk body 1 through a bearing assembly, and is thus arranged on the disk bottom 11. In the case where the blade assembly 2 and the drive device are driven by magnetic force, the blade assembly 2 is adsorbed by magnetic force or limited by a limiting mechanism and is arranged on the disk bottom 11. Along the radial direction of the blade shaft 22, the tip of the blade 21 (the tip of the first blade 211 in the figure) is located between the edge of the disk bottom 11 and the disk side wall 12. Figure 6 The distance f that the blade tip extends beyond the edge of the disk bottom 11 is shown. Of course, the above description is based on the lowest blade (first blade 211) among the blades 21 as an example. However, based on the role played by the distance f, those skilled in the art will understand that as long as the distance between the blade tip of at least one blade 21 and the disk sidewall 12 satisfies the aforementioned relationship, it will be sufficient.

[0042] The disk sidewall 12 includes a turbulent area 121 formed corresponding to the rotation of the blade 21. The heating element 4 is arranged on the disk sidewall 12 and forms a contact surface 41 with the disk sidewall 12. The contact surface 41 at least partially overlaps with the turbulent area 121. The "at least partially overlap" means: a) completely overlap, such as Figure 6 As shown, the contact surface 41 and the spoiler region 121 are on the front and back sides, the lowest point of the contact surface 41 is higher than the lowest point of the spoiler region 121, and the highest point is lower than the highest point of the spoiler region 121: b) Partial overlap: The contact surface 41 and the spoiler region partially overlap, that is, the lowest point or the highest point of the contact surface 41 is located between the highest point and the lowest point of the spoiler region 121. Combining the above two situations a and b, the height difference z between the contact surface 41 and the spoiler region 121 can be -10mm≤z≤10mm.

[0043] As described above, since the contact surface 41 and the turbulence area 121 at least partially overlap, and the heating element 4 is arranged on the side wall 12 of the dish, and the tip of the knife is located between the edge of the bottom 11 of the dish and the side wall 12 of the dish, the fluidity of the food can be maximized, and the food heated by the heating element 4 is more easily washed away by the turbulence. As little food as possible stays in the heating area of ​​the heating element 4, avoiding the side wall 12 and the bottom 11 of the dish from being burned. In addition, when the heating element 4 is arranged on the side wall 12 of the dish, after the side wall 12 of the dish is heated, the heat is transferred to the bottom 11 of the dish and heats the food on the bottom 11 of the dish. The bottom 11 is heated by the heat transfer and is heated evenly and is not directly heated. Combined with the turbulence, the side wall 12 of the dish will not be burned, and the bottom 11 of the dish will not be burned (i.e., the bottom will be burnt). Because the bottom and the side wall of the dish are not easy to burn, the heating effect is good. For example, a higher power heating can be used, or the heating time is relatively long, making the food taste better.

[0044] See also Figure 6 and Figure 5 Combined with Figure 8 and Figure 9 , the contact surface 41 is a curved surface. Figure 6 The mid-curved surface is an arc-shaped surface. More specifically, Figure 8 and Figure 9 The heating element 4 includes a concave heating element arc surface 401, and Figure 10 The heating element 4 is shown as including an outwardly convex heating element curved surface 401, and correspondingly, the disk sidewall 12 is provided with an inwardly concave sidewall curved surface 120. Thus, after the heating element 4 is in contact with the disk sidewall 12, the heating element curved surface 401 and the sidewall curved surface 120 form the contact surface 41. Based on the function of the curved surface described later, skilled artisans will understand that the structure of the curved surface is not limited. In other embodiments, the curved surface can also be a wavy surface, etc., as long as it can achieve the function described later.

[0045] As described above, since the contact surface 41 is a curved surface, the area of ​​the curved surface is larger than that of the flat surface, thereby increasing the heat conduction area. Combined with the aforementioned features (such as turbulence), heat concentration that causes the disc body 1 to burn can be avoided.

[0046] See also Figure 6 and Figure 10 Combined with Figure 8 and Figure 9 , the curved surface (contact surface 41) is an arc-shaped surface.

[0047] As described above, the curved surface (contact surface 41) is an arc-shaped surface. In this way, while ensuring that the disk side wall 12 is not easily burned, it is also convenient for the disk body 1 and the heating element 4 to be assembled, such as by welding.

[0048] See also Figure 6The disk sidewall 12 is arc-shaped, and the corresponding radius R is 30mm≤R≤65mm, for example, 30mm, 33mm, 35mm, 38mm, 40mm, 42mm, 45mm, 48mm, 50mm, 53mm, 55mm, 58mm, 60mm, 63mm or 65mm, etc. The disk sidewall 12 is arc-shaped, which also ensures that the contact surface 41 formed by the disk sidewall 12 and the heating element 4 is an arc-shaped surface.

[0049] As set up above, since 30mm≤R≤65mm, not only does it meet the requirement that the aforementioned disk side wall 12 is not easily burned, but also, when the disk body 1 includes an inner disk body 119 and an outer disk body 118 covering the inner disk body 119, it is convenient to assemble the inner disk body 119 and the outer disk body 118 and the assembly quality is good. For example, when welding is used between the inner disk body 119 and the outer disk body 118, there will be no cold welds.

[0050] See also Figure 6 , the side wall 12 of the disk and the bottom 11 of the disk form an obtuse angle, Figure 6 The obtuse angle is labeled β.

[0051] As set up above, since the side wall 12 of the dish and the bottom 11 of the dish are at an obtuse angle, the side wall 12 of the dish expands outward. In this way, when the volume of the stirring space is equal, the bottom 11 of the dish is smaller, and the turbulence can maximize the fluidity of the food. Thus, the turbulence effect of the knife assembly 2 is better. Ultimately, the turbulence can more easily wash away the food on the temperature measuring head 311. Thus, the temperature measured by the temperature measuring assembly 3 is more accurate, which can avoid misjudgment caused by inaccurate temperature, and thus avoid problems such as dry burning of the heating plate assembly 10.

[0052] Continue to see Figure 6 In an embodiment of the present application, 100 degrees ≤ β ≤ 150 degrees, for example, 100 degrees, 105 degrees, 108 degrees, 110 degrees, 112 degrees, 115 degrees, 118 degrees, 120 degrees, 123 degrees, 125 degrees, 128 degrees, 130 degrees, 133 degrees, 135 degrees, 138 degrees, 140 degrees, 143 degrees, 145 degrees, 148 degrees or 150 degrees.

[0053] See also Figure 6 In conjunction with the figure, the tray body 1 includes an inner tray body 119 and an outer tray body 118 covering the inner tray body 119. The edge of the outer tray body 118 is folded back to form a receiving groove 110. Figure 8 and Figure 9 , the edge of the heating element 4 includes a corner 410. Figure 6 , the corner 410 is located in the receiving groove 110 .

[0054] As described above, by positioning the corner 410 within the receiving groove 110, the outer plate 118 and the inner plate 119 can be positioned for assembly, facilitating assembly of the outer plate 118 and the inner plate 119. When the outer plate 118 and the inner plate 119 are welded, the receiving groove 110 can also prevent the solder from flowing out during the welding process.

[0055] See also Figure 6 Combined with Figure 5 and Figure 7 The edge of the tray body 1 is bent to form a positioning portion 13 for assembling with the cup holder 30 . In the embodiment of the present application, the edge of the inner tray body 119 is provided with the positioning portion 13 .

[0056] As described above, the positioning portion 13 is used to position the heating plate assembly 10 so as to facilitate assembly of the heating plate assembly 10 to the cup holder 30 .

[0057] See also Figure 8 、 Figure 9 and Figure 10 The heating element 4 includes an outer side surface 42 connected to the contact surface 41. The outer side surface 42 is formed by connecting multiple side surfaces 421. The corners 410 formed by adjacent side surfaces 421 all protrude outward. Therefore, the outer side surface 42 of the heating element 4 does not have a structure such as an undercut.

[0058] As described above, since the outer side surface 42 connected to the contact surface 41 includes multiple side surfaces 421, the corners 410 formed by adjacent side surfaces 421 protrude outward. In this way, the heating element 4 does not have an undercut structure, which facilitates demolding.

[0059] See also Figure 6 Combined with Figure 7 , the heating plate assembly 10 satisfies at least one of the following relationships:

[0060] a) The width of the orthographic projection of the dish sidewall 12 on the horizontal plane is C, and the width between the dish sidewalls 12 is L, where 0≤C / L≤1 / 2, for example, 0≤C / L≤1 / 4. The dish sidewall 12 is located in the vertical direction, with a width C=0; C / L=0. As described above, since 0≤C / L≤1 / 2, the space enclosed by the dish sidewall 12 and the dish bottom 11 is relatively small, facilitating airflow disturbance. When the dish sidewall 12 is an arcuate wall, the curvature is maintained, resulting in a better airflow disturbance effect, thereby better preventing food from sticking to the airflow disturbance area 121 and preventing the dish sidewall 12 from burning.

[0061] b) Along the axial direction of the blade shaft 22, the minimum distance a between the blade 21 and the disk base 11 is defined as "a." The depth of the disk body is defined as "A," and the ratio of 1 / 4 ≤ a / A ≤ 3 / 4 is defined as "1 / 4 ≤ a / A ≤ 3 / 4." This arrangement ensures that the turbulence region 121 is sufficiently wide, thus providing a larger area and preventing heat from concentrating and burning the disk sidewall 12. The distance a or depth can be determined based on either the inner or outer surface of the disk base 11.

[0062] c) Along the axial direction of the blade shaft 22, the distance H between the bottom surface of the heating element 4 and the tray bottom 11 is 0 < H ≤ 15 mm. Here, the distance H can be based on the inner surface of the tray bottom 11 or the outer surface of the tray bottom 11. As described above, 0 < H ≤ 15 mm ensures that the heating element 4 is spaced apart from the tray bottom 11, thereby preventing direct heating of the tray bottom 11 and preventing the tray bottom 11 from being burned.

[0063] d) Along the radial direction of the pan base 11, the distance P between the tip of the blade 21 and the pan sidewall 12 is 1.5 mm ≤ P ≤ 10 mm. This arrangement prevents large particles of food from becoming stuck between the blade tip and the pan sidewall 12 due to the smaller distance, resulting in a more delicate blending of the food. This also results in a more delicate food that flows more easily, resulting in a better flow disturbance. Furthermore, there is sufficient distance to prevent the blade tip from scratching the pan sidewall 12.

[0064] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In the second aspect, an embodiment of the present application discloses a food processor. The food processor includes any one of the aforementioned heating plate assemblies 10, a driving device, and a stirring cup 20. The heating plate assembly 10 includes a knife assembly 2, and the driving device drives the knife assembly 2 to rotate in the stirring cup 20. In an embodiment of the present application, the food processor includes a stirring cup assembly 100 and a main unit 200. The stirring cup assembly 100 includes the heating plate assembly 10, the stirring cup 20, the cup holder 30, the cup holder bottom cover 40, the cup cover assembly 50, a coupler 60, and a handle assembly 70. The driving device is provided on the main unit 200.
