Method of baking both sides of ingredients and an electric cooker used therefor

Abstract

In a method of baking both sides of ingredients between upper and lower dies with upper and lower electric heaters respectively, a temperature of one of the lower and upper dies is detected. Based on temperature information detected thereby, consumed power of the other of the lower and upper dies is controlled, thereby making a temperature of the lower die closer to that of the upper die, thereby baking both sides of the ingredients.

1 . A method of baking both sides of ingredients, the method comprising:
 putting an upper die on a lower die, wherein a recess is respectively provided on a lower surface of the upper die and an upper surface of the lower die so as to be opposite to each other, and wherein the recess of the upper die is formed so as to be shallower than that of the lower die;   heating the lower die and the upper die with electric heaters having the same rated power to bake upper and lower surfaces of the ingredients,   detecting a temperature of one of the lower die and the upper die to control consumed power of the electric heater for heating the other of the lower die and the upper die, of which a temperature is not detected; and   making the temperature of the lower die and that of the upper die closer to each other to bake the ingredients.   
     
     
         2 . The method according to  claim 1 , wherein the consumed power of the electric heater for heating the die of which the temperature is not detected is controlled according to a previously determined relation between the consumed power of the electric heater for heating said die and the temperature of said die. 
     
     
         3 . The method according to  claim 2 , wherein the die of which the temperature is detected is the lower die and the die of which the temperature is not detected is the upper die, wherein a mass of the upper die is equal to or less than that of the lower die, wherein the lower die is heated by its electric heater at the maximum rated consumed power of the electric heater, and wherein the consumed power of the electric heater for heating the upper die is controlled according to a previously determined relation between the consumed power of the electric heater for heating the upper die and the temperature of the upper die, thereby making the temperature of the lower die and that of the upper die closer to each other. 
     
     
         4 . The method according to  claim 3 , wherein the consumed power of the electric heater for heating the upper die is preset to get smaller stepwise from the rated power such that one consumer power value corresponding to the mass of the upper die is selected from a plurality of stepwise consumed power values corresponding to each reduction rate of the mass of the upper die to make the temperature of the lower die and that of the upper die closer to each other. 
     
     
         5 . An electric cooker comprising:
 a lower housing;   a lower die on an upper surface of the lower housing;   an upper housing mounted to pivot upward with respect to the lower housing;   an upper die on a lower surface of the upper housing, a lower surface of the upper die covering an upper surface of the lower die;   a temperature sensor for detecting a temperature of the upper die or the lower die;   a lower electric heater disposed in the lower housing to heat the lower die;   an upper electric heater disposed in the upper housing to heat the upper die and having rated power which is the same as that of the lower electric heater; and   a heater power control device connected at one side to the temperature sensor and at the other side to the other of the lower die and the upper die, of which a temperature is not detected, thereby controlling consumed power of the electric heater for heating the other of the lower die and the upper die, of which the temperature is not detected and making the temperature of the lower die and that of the upper die closer to each other,   wherein a recess is respectively provided on the lower surface of the upper die and the upper surface of the lower die so as to be opposite to each other, and wherein the recess of the upper die is formed so as to be shallower than that of the lower die.   
     
     
         6 . The electric cooker according to  claim 5 , wherein the consumed power of the electric heater for heating the die of which the temperature is not detected is controlled by the heater power control device according to a previously determined relation between the consumed power of the electric heater for heating said die and the temperature of said die, thereby making the temperature of the lower die and that of the upper die closer to each other. 
     
     
         7 . The electric cooker according to  claim 6 , wherein the die of which the temperature is detected is the lower die and the die of which the temperature is not detected is the upper die, wherein a mass of the upper die is equal to or less than that of the lower die, wherein the lower die is heated by its electric heater at the maximum rated consumed power of the electric heater, and wherein the consumed power of the electric heater for heating the upper die is controlled according to a previously determined relation between the consumed power of the electric heater for heating the upper die and the temperature of the upper die, thereby making the temperature of the lower die and that of the upper die closer to each other. 
     
     
         8 . The electric cooker according to  claim 7 , further comprising a plurality of preset switches connected to the heater power control device and having different consumed power, one of the preset switches being selected to reduce the temperature of the upper die and making the temperature of the lower die and that of the upper die closer to each other to bake the ingredients uniformly. 
     
     
         9 . The electric cooker according to  claim 7 , further comprising a semiconductor switch connected to the heater power control device at one side and the upper die at the other side, an ON signal for turning on AC voltage and an OFF signal for turning off AC voltage being sent from the heater control device to the semiconductor switch for controlling the consumed power of the electric heater for heating the upper die by adjusting a ratio of an ON signal to an OFF signal. 
     
     
         10 . The electric cooker according to  claim 7 , wherein the temperature sensor is in contact with the lower die.
