  • Patent number: 7446283
    Abstract: A cooking appliance and a method of controlling the cooking process in the cooking appliance. The cooking appliance includes a heating device, especially for grilling. To improve the browning process of food in the cooking appliance the radiation time of the cooking appliance is increased. The time is increased by a temporary cooling-down phase where the temperature is reduced, that is initiated by opening the cooking appliance door, for example, to turn the food being browned. The cooking appliance then increases the temperature again over a subsequent heating-up phase initiated by closing the cooking appliance door.

  • Publication number: 20080236405
    Abstract: A heat detecting device and a cooking apparatus using the same, in which the operation of a heating unit is appropriately controlled according to the presence or absence and/or type of cooking container (e.g., pan or pot) on the cooking apparatus. When there is no cooking container on the cooking apparatus, the duty cycle of the heat source is reduced, thereby preventing unnecessary operation of the heat source. Accordingly, power consumption is reduced. On the other hand, when there is a cooking container on the cooking appliance, the duty cycle of the heat source is increased, thereby making faster more efficient cooking possible.

  • Publication number: 20080118614
    Abstract: A device for cooking food is disclosed. The device has an elongated body for containing the food to be cooked with a heater at one end and a simmer temperature sensor at the other end. The heater initially brings the substance contained in the elongated member to a boil which is sensed by a boiling sensor. The boiling temperature sensor may be integral with the heater. Once a controller connected to the heater receives a signal from the boiling sensor indicating that the substance is boiling, the controller alternates the power to the heater between a simmer power level and a non-simmer power level which is lower than the simmer power level. The controller controls the power level of the heater in response to a signal from the simmer temperature sensor. The simmer temperature sensor sends a signal to the controller when the temperature of the substance at the end remote from the heater falls below a predetermined simmer temperature.

  • Patent number: 6862494
    Abstract: An automated cooking system (10) cooks food (12) accompanied by machine-readable indicia, such as a bar code (16) read by a reader (18). Cooking data, including function coefficients, are accessed from an Internet server (20) based on the information in the bar code. An oven (40) cooks the food in phases in response to the cooking data and one or more monitored food parameters of humidity, temperature and weight. The cooking is controlled by functions in which one or more food parameters are multiplied by coefficients that vary according to food type.

  • Publication number: 20040261625
    Abstract: The significant difference that this present invention has compared to prior art is in its individual containers and compartments. These individual containers allow caregivers to differentiate between each infant's dietary constraints. It attempts to simplify the feeding process by providing a method for preparing multiple bottles mechanically. Another benefit comes from the devisee's ability to release each container from its housing so that it may be properly sanitized. The containers may also be brought home, so that parents do not have to worry about leaving formula at their day-care center, where it might be given to another infant. The container can be brought to the day-care center like a child brings his or her lunch box to school. Once there, it can be reinserted and provide a full day's nourishment.

  • Publication number: 20040237796
    Abstract: A household appliance for cooking under pressure, the appliance being provided with bistable calibrated leakage means suitable for taking up an open position in which the pressure inside the appliance is allowed to increase continuously to above a determined pressure P0, while also allowing air to be bled from the appliance, and a closed position corresponding to an absence of leakage of air to the outside, the open position being sustained until a predetermined pressure value P1 is reached. Rather than being sustained until the predetermined pressure P1 is reached, the open position is sustained for one of a predetermined time interval &Dgr;t after P0 is reached, and until a predetermined temperature value T1 is reached. The appliance is provided with at least one closure/opening safety means whose position is sensitive to pressure.

  • Publication number: 20040226454
    Abstract: Slow cooking over solid fuel in an enclosed barbeque pit is carried out by the use of an electronically controlled impeller which directs a flow of air toward the fuel. The duty cycle of the impeller is controlled by an electronic controller which is responsive to the internal temperature of the food and to the temperature of the pit atmosphere. As the internal temperature of the food increases, the temperature of the pit atmosphere gradually decreases.

  • Patent number: 6810791
    Abstract: Termination of cooking in a safe state can be judged without fail. At S5, a cooking timer according to a selected cooking menu is started and at S6 it is judged that the cooking timer finishes. Then, at S7 a burner controller stops heating by burners while a pressure valve is opened so that the pressured air in an oil vat can be released. Because of the release, when pressure in the oil vat 4 reaches a low value which is safe enough to release the lid, a second pressure switch with low set pressure is turned OFF. When it is confirmed that the second pressure switch is turned OFF at S8, a cooking controller 23 alarms a buzzer to notify termination of the cooking at S9.

    Abstract: A radiant heater is provided, which is subdivided into three concentric areas and which can be mounted under a glass ceramic cooking area. It has a rod controller and the two innermost heating areas are jointly protected against excess temperatures by means of the rod controller. The outermost heating area has a low surface power of 2.5 W/cm2, for example, and consequently does not have to be monitored by the rod regulator with regards to the danger of an excess temperature for a glass ceramic cooking area.

  • Patent number: 6789461
    Abstract: A water level detecting device for a percolator includes a pot body having a coffee powder container provided on the topside and a buoy device installed in the interior. The buoy device consists of a buoy rod fitted thereon with a buoy. A detecting device (a magnetic induction element or a photoelectric element) is provided on a power base or on the outer wall of the pot body or in the buoy rod. The buoy is able to move upward and downward together with the height of the water level of a water tank of the pot body. When the water level of the water reservoir reaches a lowermost limit preset, the detecting device will interact with the buoy to cut off power of the heater of the pot body, enabling the percolator to cut off electricity automatically to enhance safety in use.
