Definitions

• the present invention relates to a cooking device that heats and cooks by raising the ambient temperature in the heating chamber to a high level. In this case, the heating amount for each menu is fixed and the finish is eliminated. is there.
• Conventional cooking methods for this type of heating cooker include temperature setting and equipment to maintain the temperature in the heating chamber at the optimum temperature for the purpose of cooking, and time setting such as a timer to set the heating time. By operating the device, "He was cooking.
• MI CROWAVE OVEN uses a humidity sensor to detect changes in humidity in the heating chamber during heating and automatically stops the heating device at the end of cooking.
• a method of automatically cooking by detecting a hydrocarbon gas that emits light when it is detected with a sensor has been considered and implemented.
• the present invention appropriately corrects the effects of fluctuation factors such as the power supply voltage, the outside air temperature, the amount of the object to be heated (food) and the initial temperature, which affect the finish of the cooking in the oven cooking.
• Cooking Finish This is to provide a heating cooker with three stable states.
• FIG. 1 is a longitudinal sectional view of a cooking device showing one embodiment of the present invention
• FIG. 2 is an electric block diagram of a control circuit of the cooking device
• FIG. 3 is a power supply voltage of 9 OV, 11 It is a figure which shows the relationship between the temperature in a heating chamber at the time of 0 heating until a batch roll (foodstuff) is baked by OV, and time.
• FIG. 1 is a cross-sectional view of the cooking device
• 1 is the main body of the cooking device
• 2 is a door provided at the front of the heating chamber so as to be openable and closable
• 3 is the door 2 ⁇
• 4 is the cooking device.
• a control circuit 6 is provided.

• the heater 11 is provided, and the heat from the heater 11 is transferred between the heating chamber 8 and the separation chamber 1 ⁇ by the rotation of the fan 13 fixed to the tip of the five axes of the motor 12.
• the food 14 is sent into the heating chamber 8 by the forced circulating air generated in the heating, and the food 14 is heated.
• Reference numeral 15 denotes a thermistor provided in the compartment 1 ⁇ .This resistance value is grasped by the control circuit 6, and when the resistance value falls below a certain value, the heater 11 is energized to make it more than a certain value. , ⁇ Turn off the power supply. By repeating this process, the heating temperature is kept constant. .
• the main circuit is composed of an AC power supply 16, a bidirectional thyristor, a door switch 15 and a heater 11.
