Referring to FIG. 1, an optimal temperature food warming apparatus 110 using a heat plate divided into zones according to the present invention includes a heat wire heating unit 120, a display unit 130, and a temperature control unit 140 do.

[0013] In the hot wire heating unit 120, electric current flows from the power cord 150 to the hot wire 121 to generate heat.

The vessel of the hot-wire heating unit 120 is heated by the heat transmitted from the hot-wire 121, and the heat is transferred to the food and the food is heated.

[0015] The heat insulator 160 prevents conduction of heat so that the food heated to each optimum temperature is not affected by the heated heat plate.

According to an embodiment of the present invention, the food is heated by the heat generated from the heat ray 121 of the heat ray heating unit 120, and the heat insulating material 160 is heated The heat on one side of the container prevents the conduction so that it does not affect the other containers that are eaten by changing the temperature, so that the optimal food for each food area can be eaten.

For example, assume that the input voltage of the power cord 150 is 220V and the resistances of the six heating wires 121 of the heating wire heating unit 120 are respectively 100Ω, 200Ω, 300Ω, 400Ω, 500Ω, and 600Ω.

At this time, the temperature regulator 140 calculates the time required for reaching the optimum temperature and calculates the amount of current necessary for warming to the target temperature, so as to divide the current converted by the DC / AC converter 151 Distributor 152 to distribute as much current as needed to each of the heat lines 111.
