Hereinafter, with reference to the accompanying drawings, the self-heating container according to the present invention will be described in detail.

1 is a perspective view of a self-heating container according to the present invention, FIG. 2 is a cross-sectional view of the self-heating container of FIG. 1, and FIG. 3 is a cross-sectional view of a planar heating layer according to the present invention.

As illustrated in FIG. 1, the self-heating container 100 includes a container body 110, a lid 120, and a handle 105 formed to directly heat a cooking object. However, the lid 120 and the handle 105 may be excluded in some cases.

Referring to FIG. 2, the container body 110 has a plurality of stacked layers, and specifically, includes an inner layer 111, a planar heating layer 112, a heat insulating layer 114, and a cover layer 115. . All of these elements, that is, the inner layer 111, the planar heating layer 112, the heat insulating layer 114, and the cover layer 115 may be formed to be transparent so that the cooking state of the object such as food in the container body 110 may be confirmed. . The container body 110 includes a side surface 110A and a bottom surface 110B, and the planar heating layer 112 also corresponds to the side surface 110A of the container body 110 so as to increase the amount of heat generated. The first heat generating layer 112A and the second heat generating layer 112B corresponding to the bottom surface 110B of the container body 110 may be included.

The inner layer 111 is a portion that contains food, etc., which is a cooking object, and transmits heat from the planar heating layer 112 to the cooking object S, and protects the planar heating layer 112. The inner layer 111 may be formed of light-transmissive heat-resistant glass, light-transmissive heat-resistant plastic, or light-transmitting ceramic in order to ensure durability and confirm the cooking state of the cooking object S.

As illustrated in FIG. 3, the planar heating layer 112 may include a light-transmissive base layer 112-1 and a thin film, and include a light-transmissive carbon layer 112-2. The base layer 112-1 serves to support the carbon layer 112-2 in the manufacturing process. The base layer 112-1 may be formed in a flexible film form so as to bend along an outer surface of the inner layer 111 having a generally cylindrical shape. Meanwhile, the carbon layer 112-2 may be directly attached to the inner layer 111, and in this case, the base layer 112-1 may be omitted.

The carbon layer 112-2 may be formed in a form in which carbon, in particular, carbon nanotubes (CNTs) are attached to the base layer 112-1. Carbon nanotubes have a hexagonal shape consisting of six carbons connected to each other to form a tubular shape. The electrical conductivity of carbon nanotubes is 100 to 1000 times better than copper, the thermal conductivity is the same as the best diamond in nature, and the strength is 100 times better than steel. Carbon fiber can be broken by only 1% deformation, while carbon nanotubes can withstand 15% deformation. In addition, carbon nanotubes have excellent exothermic properties.

The planar heating layer 112 including the carbon nanotubes has a large amount of far-infrared emission, and when irradiated to food, which is a cooking object, may promote the generation of a substance beneficial to health, and may improve the health of users around the table.

Referring to FIG. 3, a color change layer 117 printed by a temperature sensitive ink may be formed on one side of the planar heating layer 112 so as to change color according to the temperature of the planar heating layer 112. . The color change layer 117 may provide a constant visual effect or information according to the degree of heating of the planar heating layer 112 (see FIG. 9).

Referring again to FIG. 2, between the outer surface of the inner layer 111 and the planar heating layer 112 to minimize the occurrence of a gap due to thermal deformation of the inner layer 111 or the planar heating layer 112. A light conductive thermal conductivity compound 113 can be applied. In addition, the inner layer 111 and the base layer 112-1 may be selected as a material having a thermal deformation similar to that of the planar heating layer 112 at the operating temperature of the carbon layer 112-2.

The heat insulation layer 114 is covered to the outside of the planar heating layer 112 and is formed to block heat emitted to the outside of the container body 110. The heat insulating layer 114 may be formed of a resin series (eg, polycarbonate, acrylic, silica gel, etc.), ceramic, or the like having a low thermal conductivity while being formed to be transparent.

The cover layer 115 is covered outside of the heat insulation layer 114, and serves as a finishing material of the container body 110. The cover layer 115 may be formed of a resin-based or ceramic-based, such as a low thermal conductivity, so as to have a heat insulating effect. The cover layer 115 may be formed in a shape different from that of the inner layer 111 to implement various appearances. As such an example, even if the inner layer 111 is formed in a cylindrical shape, the cover layer 115 may be formed in the form of a hexahedron box.

The cover layer 115 may include a waterproofing means so that water or foreign matter does not penetrate the planar heating layer 112. To this end, the cover layer 115 may be directly coupled to the inner layer 111 so that the surface heating layer 112 and the heat insulating layer 114 are not exposed to the outside. In this case, a sealing material may be provided between the cover layer 115 and the inner layer 111.

4 is a partial cross-sectional view of the container body related to the present invention. The planar heating layer 112 disposed outside the inner layer 111 has a higher heat transfer rate as the surface contact with the inner layer 111 becomes more complete. To this end, a means for ensuring that the planar heating layer 112 is in contact with the outer surface of the inner layer 111 may be considered. 4 shows that the pressurizing rib 115-1 is formed on the cover layer 115 to press the planar heating layer 112 against the surface of the inner layer 111. The pressing ribs 115-4 are formed in the vertical direction on the inner surface of the cover layer 115, and a plurality of the pressing ribs 115-4 are disposed along the circumferential direction at regular intervals.

This will be described in terms of manufacturing process as follows. First, the planar heating layer 112 is attached to the outer surface of the inner layer 111. Then, the inner layer 111 to which the planar heating layer 112 is attached is inserted into the cover layer 115 on which the heat insulation layer 114 is disposed. In the process of inserting the inner layer 111, the pressurized ribs 115-1 disposed at regular intervals pressurize the heat insulating layer 114 and the planar heating layer 112 toward the inner layer 111 as shown in FIG. The contact with the inner layer 111 of the layer 112 becomes good.
