Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric rice cooker heating disc, specifically relates to an electric rice cooker double -tube heating disc. BACKGROUND

[0002] The electric rice cooker heating disc is a key component of the electric rice cooker, which is usually made of aluminum alloy or stainless steel material, and the aluminum alloy heating disc is one of the most common types in the electric rice cooker. The heating disc has good heat conductivity and high heat efficiency, which can transfer heat to the inner container and rice grains to ensure the taste and nutrition of food.

[0003] The existing heating disc adopts a single tube structure, that is, a group of heating wires are arranged in the heating tube groove embedded in the bottom heating disc, for example, the patent publication No. CN108495387A electric rice cooker and the manufacturing method of electric rice cooker heating disc, and the patent publication No. CN2509481Y electric rice cooker heating disc, the structure of which is a group of heating wires, and the power supply is connected by a pair of terminal posts. Such structure causes uneven winding of the heating wires, especially in the terminal post area, and the power is relatively small. In addition, the bottom disc is a flat panel body, which affects the uniform heat transfer and makes the rice grains not reach the expected effect. SUMMARY

[0004] The utility model discloses a kind of electric rice cooker double-tube heating disc, and the utility model discloses a kind of double-tube heating, so that inner container is heated evenly, and improve taste.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] An electric rice cooker double-tube heating disc, comprising a heating disc, a temperature control switch placement hole in the middle of the heating disc, the upper surface of the heating disc gradually expands outward to form a disc body, which can be matched with the bottom of the inner container, and two groups of heating tube grooves are provided on the lower surface of the heating disc, each group of heating tube grooves is installed with a group of heating wires, and each group of heating wires is connected with a terminal post.

[0007] Further, an inner heating tube groove is provided in the inner circle of the heating disc, the heating wires in the inner heating tube groove are connected with a first terminal post, an outer heating tube groove is provided in the outer circle of the heating disc, and the heating wires in the outer heating tube groove are connected with a second terminal post.

[0008] Further, three fixed corners are uniformly installed on the lower surface of the heating disc.

[0009] Further, a reinforcing rib is added to the heating disc.

[0010] Further, the outer diameter of the heating disc is 216.8 mm, and the height of the heating disc and the terminal post is 67 mm.

[0011] Furthermore, the distance between the terminal block and the center of the heating plate is 35mm-63.3mm.

[0012] The above technical solution can achieve the following beneficial effects:

[0013] Compared to existing single-tube heating plates, this novel dual-tube heating plate can handle high-power (1300W) cooking, achieving vigorous boiling and even heating of rice, thus improving its texture. Secondly, the plate's disc-shaped design allows it to fit snugly against the bottom of the inner pot, further facilitating heat transfer and ensuring uniform heating. The staggered or internal / external arrangement of the two heating tubes can be selected based on the manufacturing process to meet different design requirements. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-4 As shown, a dual-tube heating plate for a rice cooker includes a heating plate 1 with an outer diameter of 216.8 mm and an inner diameter of 206.5 mm. A temperature control switch placement hole 4 is located in the center of the heating plate 1. The upper surface of the heating plate 1 gradually expands upwards to form a plate shape, fitting snugly against the bottom of the inner pot. Two sets of heating tube grooves are provided on the lower surface of the heating plate 1, arranged internally and externally. An inner heating tube groove 6 is provided on the inner ring of the heating plate 1, with the heating wire in the inner heating tube groove 6 connected to a first terminal 5. An outer heating tube groove 8 is provided on the outer ring of the heating plate 1, with the heating wire in the outer heating tube groove 8 connected to a second terminal 7. Three fixed corners 2 are evenly installed on the lower surface of the heating plate 1. Reinforcing ribs 9 are added to the heating plate 1. The height of the heating plate and the terminal is 67 mm. The distance from the terminal to the center of the heating plate is 35 mm to 63.3 mm.

[0022] Based on the above embodiment, the two groups of heating pipe grooves can also be staggered, that is, the inner heating pipe groove 6 and the outer heating pipe groove 8 are staggered with each other to form a double helix shape, and the terminal posts 3 thereon are also provided with the first terminal post 5 and the second terminal post 7 according to a reasonable layout mode.

[0023] After the heating, the heating pipe groove will not be broken, the structure is firm and firm, the whole heating disc surface is well machined, and the deformation of the cutting surface on the same circumference is controlled below 0.1mm.

[0024] The middle surface of the heating disc is flat, and the edge is gradually widened, and the curvature is consistent with the curvature of the outer surface of the inner container.
