Problems solved by technology

Existing electric grills using such heating wires have the problem that the heat energy applied to the grill cannot be transmitted evenly
In addition, since there is a gap formed between the grill pan and the heating wire, there is a problem of large heat loss due to the fact that heat cannot be directly applied to the area of ​​the grill pan
Due to these problems, the existing electric griddles that use heating wires have a very slow heating rate compared to equipment using gas, and the preheating time becomes longer in order to cook at an appropriate temperature, so the cooking quality of the food is very poor.
[0006] In addition, due to local heating, the type of material used for the baking pan is also limited according to the specific heat of the material.
For example, when a slate is used as a baking pan, the local temperature difference is serious due to the high specific heat ratio, and when the temperature difference is serious, the fatal problem of slate cracking may occur

manufacture example 1

[0107]

[0108] 1.5 g of carbon nanotubes (Hanwha Nano Technology Co., Ltd.) were added to the Erlenmeyer flask, and 33.75 g of α-terpineol (α-terpineol) and 1.25 g of ethylcellulose (Ethylcellulose) were dropped into the organic solvent. 5g of silicon-based adhesive (RSN-0806, Dow Corning) and 0.75g of dispersant (DISPERBYK-192, BYK). Next, the Erlenmeyer flask was installed in a stirrer, and stirred for 60 minutes to sufficiently disperse the exothermic composition.

Embodiment 1

[0110] A stone plate (longevity stone) having an area of ​​300 mm×195 mm and a thickness of 20 mm was prepared as a baking tray. Wash the surface of the baking pan with ethanol, and perform heat treatment at 250°C for 30 minutes to remove impurities that may exist on the surface of the baking pan.

[0111] The heat-generating composition produced in Production Example 1 was coated on the lower surface of the bakeware after the above treatment with a wet thickness of 600 μm, and thermally cured at 300° C. for 30 minutes to coat the heat-generating layer on the bakeware. Such a coating process was repeated again to finally manufacture an electric grill pan coated with a heat generating layer having a wet thickness of 1.2 mm on the lower surface of the grill pan. At this time, the area of ​​the heat generating layer was 220 mm×160 mm.

[0112] In addition, a pair of copper electrodes are respectively bonded to both ends of the heat generating layer. At this time, as Figure 7 A...

Embodiment 2

[0115] The same method as in Example 1 was implemented except that the 20 mm baking pan in Example 1 was replaced with a 15 mm thick baking pan.

Abstract

An electric roasting pan according to the present invention comprises: a roasting pan; a heating layer being in surface contact with the roasting pan and comprising a carbon nanotube and a silicone-based adhesive; and an electrode in contact with the heating layer. The electric roasting pan has excellent thermal efficiency thanks to the minimal heat loss thereof, can reach a target temperature within a short time to reduce a preheating time, and affords excellent cooking quality. Furthermore, the electric roasting pan can substantially prevent the occurrence of temperature deviation across thearea of the roasting pan during a temperature increase and is of high durability and safety.

Description

technical field [0001] The invention relates to an electric baking pan. Background technique [0002] Usually, in a family or a restaurant, gas stoves or gas stoves are mostly used as equipment for cooking food or grilling meat. Such a conventional heating device using gas as energy has the advantages of ease of use and low fuel cost due to widespread availability of facilities. However, since gas pipeline facilities are indispensable, places of use are limited. In addition, equipment that uses gas as energy generates heat directly through combustion, so there is a very high risk of explosion or fire, so the recent trend is the widespread use of high-safety heating equipment that uses electric energy such as electric grills in homes. . [0003] Electric grills are electric heaters that generate heat by receiving electrical energy. The electric heater is usually constructed such that there is an electric heating part that uses electric energy to generate heat inside the bo...
