Technical Field

[0001] The present application relates to the technical field of cooking utensils, and in particular to an electric hot pot with zoned heating. Background Art

[0002] At present, the pots used for cooking hot pot are usually of the overall heating structure. When heating, the water in the entire pot cavity will be heated. Pots such as the double-sided pot, the four-grid pot, and the nine-grid pot, which divide the pot cavity into multiple areas, are only separated by partitions. Different areas are not insulated. When heating, all areas will be heated, which makes it inconvenient for users to use and consumes a lot of electricity. Utility Model Content

[0003] Based on this, it is necessary to provide an electric hot pot with zoned heating, which can divide the inner cavity of the pot body into multiple heating chambers through the insulation part, each heating chamber is heated independently, and the temperatures between adjacent heating chambers do not interfere with each other.

[0004] A zoned heating electric hot pot comprises a pot body and a heating base, wherein the bottom of the pot body is provided with an insulation portion extending upward, wherein the insulation portion divides the inner cavity of the pot body into a plurality of heating chambers, and the heating base comprises a base body arranged below the pot body and a plurality of heating units arranged in the base body and corresponding to the heating chambers, wherein the heating units are located in the vertical projection of the corresponding heating chambers and are used to heat each of the heating chambers separately.

[0005] The electric hot pot with zoned heating provided by the present application is provided with a heat insulating part, which can block the transfer of heat, and a heating unit for heating each heating chamber individually is provided. Since the heating unit is in the vertical projection of the corresponding heating chamber, the heating unit can heat the corresponding heating chamber more specifically, thereby improving the heating efficiency, and the temperatures between adjacent heating chambers do not interfere with each other, thereby meeting the use requirements of zoned heating. When the user needs to cook food in a certain heating chamber, he only needs to turn on the heating unit corresponding to the heating chamber, and other heating chambers will not be heated, or different heating chambers can be controlled to be heated according to different cooking curves, which is more flexible and convenient to use and saves electricity.

[0006] In one of the embodiments, the heat insulating portion separates the bottom walls of adjacent heating chambers.

[0007] In this way, adjacent heating chambers will not transfer heat through the bottom wall, so that the heat insulation part has a better heat insulation effect.

[0008] In one embodiment, the insulation portion is annular and divides the inner cavity of the pot body into an inner chamber and an outer chamber surrounding the outer side of the inner chamber, and the heating unit includes an inner heating unit arranged corresponding to the inner chamber and an outer heating unit arranged corresponding to the outer chamber.

[0009] Thus, the heat insulation part has a simple structure, and the inner cavity of the pot body is divided into two heating chambers. The heating chamber has a simple structure, is easy to use, and is easy to process and clean. The inner heating unit and the outer heating unit heat the inner chamber and the outer chamber respectively, thereby improving the temperature rise efficiency of the inner chamber and the outer chamber.

[0010] In one embodiment, the inner heating unit is located below the inner chamber and arranged along the circumference of the inner chamber, and / or the outer heating unit is located below the outer chamber and arranged along the circumference of the outer chamber.

[0011] In this way, the inner heating unit can heat the inner chamber more efficiently, and / or the outer heating unit can heat the outer chamber more efficiently.

[0012] In one embodiment, the bottom wall of the inner chamber is higher than the bottom wall of the outer chamber, and a groove is formed between the bottom wall of the inner chamber and the bottom wall of the outer chamber.

[0013] In this way, by providing a corresponding boss on the heating base, the pot body and the heating base can be positioned and matched, thereby preventing the pot body from translating relative to the heating base.

[0014] In one of the embodiments, a boss is provided at the center of the base body, and when the pot body is placed on the heating base, the boss is embedded in the groove.

[0015] In this way, the cooperation between the boss and the groove can realize the positioning of the pot body, thereby preventing the pot body from moving relative to the heating base.

[0016] In one of the embodiments, the internal heating unit is disposed inside the boss and along the circumference of the boss.

[0017] In this way, the inner heating unit is closer to the inner chamber, so that the heating efficiency of the inner chamber is higher, and the inner heating unit arranged along the circumference of the boss makes the bottom wall of the inner chamber heated more evenly.

[0018] In one embodiment, the insulation portion is in the shape of a letter "I" or a curve, and divides the inner cavity of the pot body into a left chamber and a right chamber, and the heating unit includes a left heating unit arranged corresponding to the left chamber and a right heating unit arranged corresponding to the right chamber.

[0019] In this way, the left heating unit and the right heating unit heat the left chamber and the right chamber respectively, thereby improving the temperature rise efficiency of the left chamber and the right chamber respectively.

[0020] In one embodiment, the bottom wall of the left chamber is higher than the bottom wall of the right chamber, and the base body is provided with a limiting groove corresponding to the right chamber. When the pot body is placed on the heating base, the protruding portion of the right chamber relative to the bottom wall of the left chamber is embedded in the limiting groove.

[0021] In this way, the right chamber and the limiting groove cooperate to realize the positioning of the pot body, thereby preventing the pot body from moving relative to the heating base.

[0022] In one of the embodiments, the heating unit is configured as a heating tube or a heating film, or the heating unit is configured as an electromagnetic heating unit, and a composite heating layer is provided at the bottom of the pot body corresponding to the heating chamber, and the composite heating layer is made of metal iron.

[0023] In this way, the heating tube has a simple structure and heats up quickly. The heating film not only heats up quickly, but also takes up little space, which is conducive to the miniaturization design of the product. The heating unit is set as an electromagnetic heating unit, and a composite heating layer is set at the bottom of the pot body, so that the pot body can be heated not only by the heating base, but also by the induction cooker.

[0039] See also Figures 1 to 4 The present application provides an electric hot pot with zoned heating, comprising a pot body 10 and a heating base 20. The bottom of the pot body 10 is provided with an insulation part 11 extending upward, and the insulation part 11 divides the inner cavity of the pot body 10 into a plurality of heating chambers 101. The heating base 20 comprises a base body 21 arranged below the pot body 10 and a plurality of heating units 22 arranged in the base body 21 and corresponding to the heating chambers 101. The heating unit 22 is located in the vertical projection of the corresponding heating chamber 101, and is used to heat each heating chamber 101 separately. In this way, since the insulation part 11 is provided, the insulation part 11 can block the transfer of heat, and the heating unit 22 for heating each heating chamber 101 separately is provided. Since the heating unit 22 is located in the vertical projection of the corresponding heating chamber 101, the heating unit 22 can heat the corresponding heating chamber 101 more specifically, thereby improving the heating efficiency, and the temperatures between adjacent heating chambers do not interfere with each other, thereby meeting the use requirements of zoned heating. When the user needs to use a certain heating chamber 101 to cook food, he only needs to turn on the heating unit 22 corresponding to the heating chamber 101, and other heating chambers 101 will not be heated, or different heating chambers 101 can be controlled to be heated according to different cooking curves, which is more flexible and convenient to use and saves electricity.

[0040] The heat insulating part 11 separates the bottom walls of adjacent heating chambers 101. In this way, the adjacent heating chambers 101 will not transfer heat through the bottom walls, so that the heat insulating part 11 has a better heat insulating effect.

[0041] In this embodiment, a heat insulating groove 111 is provided on the bottom surface of the heat insulating portion 11, and the heat insulating groove 111 separates the bottom walls of adjacent heating chambers 101. The heat insulating groove 111 can prevent the bottom walls of adjacent heating chambers 101 from contacting each other, thereby effectively separating the bottom walls of adjacent heating chambers 101. In addition, the heat insulating groove 111 has a simple structure and is easy to process.

[0042] Furthermore, the heat insulating groove 111 may be filled with heat insulating material to ensure the heat insulating effect. The heat insulating groove 111 may also be filled with air directly without heat insulating material, and air also has a certain heat insulating effect.

[0043] See also Figure 1 and Figure 2 In one embodiment, the heat insulating portion 11 is annular, and the heat insulating portion 11 divides the inner cavity of the pot body 10 into an inner cavity 102 and an outer cavity 103 surrounding the inner cavity 102. In this way, the heat insulating portion 11 has a simple structure, and the inner cavity of the pot body 10 is divided into two heating chambers 101. The heating chamber 101 has a simple structure, is easy to use, and is easy to process and clean. Figure 3 and Figure 4 In this embodiment, the heating unit 22 includes an inner heating unit 222 corresponding to the inner chamber 102 and an outer heating unit 223 corresponding to the outer chamber 103. In this way, the inner heating unit 222 and the outer heating unit 223 heat the inner chamber 102 and the outer chamber 103 respectively, thereby improving the temperature rise efficiency of the inner chamber 102 and the outer chamber 103.

[0044] Furthermore, the inner heating unit 222 is located below the inner chamber 102 and is arranged along the circumference of the inner chamber 102, so that the inner heating unit 222 can heat the inner chamber 102 more efficiently. Similarly, the outer heating unit 223 is located below the outer chamber 103 and is arranged along the circumference of the outer chamber 103, so that the outer heating unit 223 can heat the outer chamber 103 more efficiently.

[0045] For further information, see Figure 2 and Figure 4 In one embodiment, the bottom wall of the inner chamber 102 is higher than the bottom wall of the outer chamber 103, and a groove 106 is formed between the bottom wall of the inner chamber 102 and the bottom wall of the outer chamber 103. In this way, by providing a corresponding boss on the heating base 20, the pot body 10 and the heating base 20 can be positioned and matched, thereby preventing the pot body 10 from moving relative to the heating base 20.

[0046] Further, a boss 210 is provided at the center of the base body 21. When the pot body 10 is placed on the heating base 20, the boss 210 is embedded in the groove 106. In this way, the boss 210 cooperates with the groove 106 to realize the positioning of the pot body 10, thereby preventing the pot body 10 from translating relative to the heating base 20. It can be seen that the boss 210 cooperates with the groove 106 to play a positioning role, so that when the pot body 10 is installed on the heating base 20, the boss 210 cooperates with the groove 106 for pre-positioning, which can improve the assembly efficiency; after the pot body 10 is installed on the heating base 20, the boss 210 cooperates with the groove 106 for positioning, which can prevent the pot body 10 from being offset and affecting the heating effect of the heating unit 22 on the heating chamber 101, and can prevent the pot body 10 from translating away from the heating base 20. It can be understood that the pot body 10 can be set to be detachably connected to the heating base 20, or it can be set to be non-detachably connected to the heating base 20, and the present application does not limit this. In this embodiment, the base body 21 includes a first heating plate 211 and a second heating plate 212. The second heating plate 212 is annular and is arranged around the outside of the first heating plate 211. The first heating plate 211 partially protrudes from the upper surface of the second heating plate 212 to form a boss 210. Further, when the pot body 10 is placed on the heating base 20, the first heating plate 211 is against the bottom wall of the inner chamber 102, and the second heating plate 212 is against the bottom wall of the outer chamber 103. In this way, efficient heat transfer between the first heating plate 211 and the bottom wall of the inner chamber 102, and efficient heat transfer between the second heating plate 212 and the bottom wall of the outer chamber 103 can be achieved.

[0047] Furthermore, the inner heating unit 222 is disposed in the boss 210 and is disposed along the circumference of the boss 210. Thus, the inner heating unit 222 is closer to the inner chamber 102, so that the heating efficiency of the inner chamber 102 is higher, and the inner heating unit 222 disposed along the circumference of the boss 210 makes the bottom wall of the inner chamber 102 heated more evenly. Similarly, the outer heating unit 223 is disposed along the circumference of the base body 21, so that the bottom wall of the outer chamber 103 is heated more evenly.

[0048] like Figure 3 and Figure 4 As shown, the inner heating unit 222 has a first terminal 2221, which is used to connect to an electric wire, and the outer heating unit 223 has a second terminal 2231, which is used to connect to an electric wire, and the first terminal 2221 and the second terminal 2231 are located on different sides of the heating base 20. In this way, the electric wires connected to the inner heating unit 222 and the electric wires connected to the outer heating unit 223 can be prevented from interfering with each other, which is conducive to the neat arrangement of the electric wires.

[0049] See also Figures 5 to 8As shown, the heat insulating portion 11 is in a straight line or a curve shape, and divides the inner cavity of the pot body 10 into a left chamber 104 and a right chamber 105, and the heating unit 22 includes a left heating unit 224 corresponding to the left chamber 104 and a right heating unit 225 corresponding to the right chamber 105. In this way, the left heating unit 224 and the right heating unit 225 heat the left chamber 104 and the right chamber 105 respectively, thereby improving the temperature rise efficiency of the left chamber 104 and the right chamber 105.

[0050] Further, in one embodiment, the bottom wall of the left chamber 104 is higher than the bottom wall of the right chamber 105. Correspondingly, the base body 21 is provided with a limiting groove 215 corresponding to the right chamber 105. When the pot body 10 is placed on the heating base 20, the portion of the right chamber 105 protruding relative to the bottom wall of the left chamber 104 is embedded in the limiting groove 215. In this way, the right chamber 105 and the limiting groove 215 cooperate to achieve the positioning of the pot body 10, thereby preventing the pot body 10 from translating relative to the heating base 20. It can be understood that in this application, "left side" and "right side" are relative positional relationships. By rotating a certain angle, "left side" can be "right side", "right side" can also be "left side", or "left side" and "right side" can be "front side" and "rear side" respectively.

[0051] exist Figures 1 to 4 In the embodiment shown, the heat insulation part 11 is annular. Figures 5 to 7 In the embodiment shown, the heat insulation part 11 is in the shape of a straight line. Figure 8 In the illustrated embodiment, the heat insulating portion 11 is in a curved shape, but is not limited thereto. In other embodiments, the heat insulating portion 11 may also be in a "cross" shape, a "rice" shape, a "well" shape, or other shapes. The present application does not limit the number and shape of the heat insulating portion 11 and the heating chamber 101, as long as the heat insulating portion 11 can divide the inner cavity of the pot body 10 into a plurality of heating chambers 101, each heating chamber 101 is provided with a corresponding heating unit 22, and each heating unit 22 can independently heat each heating chamber 101.

[0052] In the present application, the pot body 10 is circular, but is not limited thereto. In other embodiments, the pot body 10 may also be other shapes such as square, hexagonal, octagonal, or elliptical.

[0053] Furthermore, in one embodiment, the heating unit 22 is configured as a heating tube, which has a simple structure and heats up quickly. However, it is not limited thereto. In other embodiments, the heating unit 22 may also be configured as a heating film, which not only heats up quickly but also takes up little space, which is conducive to the miniaturization design of the product. In other embodiments, the heating unit 22 may also be configured as an electromagnetic heating unit, and a composite heating layer is provided at the bottom of the pot body 10 corresponding to the heating chamber 101, and the composite heating layer is made of metal iron. In this way, the pot body 10 is heated by electromagnetic heat generation, so that the pot body 10 can be heated not only by the heating base 20, but also by an induction cooker.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
