Definitions

  • This invention relates to a cooking apparatus control method used to maintain the cooking performance and reduce the energy consumption in household appliances preferably in electric ovens.
  • patent application No. DE3804678 discloses that the rotation speed providing the abso ⁇ tion of the vapor by a channel and humidity; and temperature values in the vapor are controlled by means of sensors.
  • the object of this invention is to provide a cooking apparatus control method used to maintain the cooking performance and reduce the energy consumption by controlling the fan and the heater.

  • the switch of the fluid in the thermostat (7) is set to a level where the switch can be operated mechanically when the user selects the temperature values. Due to the environment and the structure of the thermostat (7) there is an error rate (Deltal) during the operation under the selected values.
  • the method which is the subject of this invention, uses an operation interval (Delta) with respect to such effects like the environmental conditions. Delta is a value gradually decreasing in accordance with the environmental conditions (Fig. 4).

  • a thermostat (7) including the fluid controls the motor (4), which operates both the heater (2) and the fan (3).
  • the thermostat (7) As the fluid is heated late, when the thermostat (7) is set to a "Toperation" temperature value, temperature allows the operation of the heater (2) until the "Toperation+Delta” and disables the motor (4) which rims both the heater (2) and the fan (3) when this value is achieved.

  • the method which is the subject of this invention, includes the following steps:
  • cooking apparatus (1) comprises a lid (6), which controls the opening and closing of the funnel (5).
  • the motor which runs the fan (3) and the heater (2) are stopped being operated and heat and humidity are transferred from the funnel (5) by opening the lid (6).
  • the environment temperature decreases and when "Toperation-Delta” value is achieved, the lid (6) is closed and the motor (4) is started to be operated until "T+Delta” value.
  • cooking apparatus (1) comprises a control card (8), which controls its operation.
  • the motor (4) which runs the fan (3) and the heater (2) are stopped being operated by the control card (8) and heat and humidity are transferred from the funnel (5) by opening the lid (6).
  • the environment temperature decreases and when "Toperation-Delta” value is achieved, the lid (6) is closed and the motor (4), which runs the fan (3) and the heater (2), is started to be operated until "T+Delta" value.
  • thermodynamic rules these steps are continued to be taken until the temperature of the fluid in the thermostat (7) is equalized with the temperature value in the cooking apparatus including the thermostat (7) and protecting these equalized temperature values until the user switches off the cooking apparatus (1) by its own willing or a timing machine.
  • cooking apparatus (1) Since “T” which is the temperature required to be kept in balance is “Toperation” temperature value determined by the user, cooking apparatus (1) is provided to achieve the temperature value required by the user by maintaining the cooking quality and reducing the energy consumption. Because as long as the heater (2) is operated, the environment is heated in a short time by operating the fan (3) at the same time and the entire surface of the foods are equally utilized from the so-called temperature and additionally when the heater (2) and the fan
  • the cooking apparatus (1) is controlled without any loss from the cooking quality by means of the control card (8) by using any thermostat (7), which can measure temperature.
  • the cooking performance is increased by means of mau taining the gas fluid circulating around the foods in the cooking apparatus under control and discharging them under the control of temperature and humidity values. During these steps, less energy is consumed by the synchronous movement of both the motor (4) and the heater (2).
