  • Patent number: 8450659
    Abstract: A load control system and method of time multiplexing power to a plurality of holding shelves in a food holding cabinet to allow total cabinet power to be limited to electrical distribution capabilities. This method allows for individual shelf heaters to be utilized normally to maintain food temperatures during normal use and modulates power when multiple shelves demand heating that would normally exceed branch circuit capabilities thus tripping the breaker. The system monitors temperature of each shelf and based upon demand executes a logical demand schedule for each shelf heater output (time multiplexing or modulating AC power to each) such that total system demand does not exceed available power to the system.

  • Patent number: 8436279
    Abstract: A system is provided for supplementing the power usage of an appliance with an internal power source, such as e.g., a battery, in order to limit the overall power consumption of the appliance while in standby mode. The system can allow for replenishing the internal power source when the appliance is not in standby mode or even when in standby mode if such will not exceed the external power source consumption limit. In the event the internal power source is not available or is reaching depletion, the system can provide for disabling electronic features of the appliance in order to maintain the external power source consumption below the desired limit.

  • Patent number: 8378265
    Abstract: A convection oven having a vapor collection system; water injection system; easily accessible electrical components; and a variable-speed, reversible blower is disclosed. The vapor collection system collects vapor from the cooking chamber during a cooking event, condenses the vapor, and drains the condensed vapor. The water injection system injects water for impact against a blower wheel for dispersion into the air circulating through the cooking chamber. The electrical components are housed within a housing that in a closed position conceals the components and in a closed position exposes the components for easy access. The rotational speed and direction of the variable-speed, reversible blower is controlled during a cooking event according to predetermined speed curves which may include one or more reversal events to achieve more uniform cooking of food. A main controller is programmable via an operator input (e.g., liquid crystal display touch screen) to control operating parameters of the oven.

  • Patent number: 8283610
    Abstract: Methods and devices for opening and closing a door of a drawer-type cooking device, enabling reduction in operation force by causing a drive mechanism not to put a load during an initial period when the door is opened or closed are provided. When a drawer body is driven by a drive mechanism including an electric motor to reach a stroke end such as a fully closed (opened) position, the drive mechanism is reversely driven only for a distance corresponding to a backlash existing in a transmission mechanism (between a pinion and a rack) and is stopped. When the drawer body is manually operated in the direction away from the stroke end, the drawer body moves without driving the drive mechanism against the inertia or load only for the distance corresponding to the backlash. As a result, the drawer body can start to be manually moved with a light burden.

  • Publication number: 20120061375
    Abstract: A system is provided for supplementing the power usage of an appliance with an internal power source, such as e.g., a battery, in order to limit the overall power consumption of the appliance while in standby mode. The system can allow for replenishing the internal power source when the appliance is not in standby mode or even when in standby mode if such will not exceed the external power source consumption limit. In the event the internal power source is not available or is reaching depletion, the system can provide for disabling electronic features of the appliance in order to maintain the external power source consumption below the desired limit.

  • Patent number: 8134100
    Abstract: A heat processing furnace comprises: a processing vessel for receiving an object to be processed by a heat process; a cylindrical heat insulation member surrounding the processing vessel; a helical heating resistor arranged along an inner peripheral surface of the heat insulation member; a support member for supporting the heating resistor. The support member includes a base part positioned on an inside of the heating resistor, and a plurality of support pieces extending radially outward from the base part through spaces between adjacent portions of the heating resistor so as to support the heating resistor, the support member being formed to have a comb-like shape. An upper surface part of each of the support pieces is formed to have a curved shape in order to reduce a frictional resistance generated when the heating resistor is moved upon a thermal expansion and a thermal shrinkage thereof.

  • Patent number: 8110779
    Abstract: There is provided a door lock control device in a heating cooker that prevents a door from being accidentally unlocked when the door is locked and a temperature inside the heating cooker is a predetermined temperature or more such as during self-cleaning. When the temperature inside the cooker is low and a thermal switch 8 of a lock detection and thermal switch portion 6 is closed, the lock detection and thermal switch portion 6 can be energized, and a power supply line 2 can supply power to a drive motor 5 to lock and unlock the door. In the case of self-cleaning or the like, the door is locked and a detection switch 7 is on a door lock side 7a, but the temperature inside the cooker is high and thus the thermal switch 8 is opened, and the power supply line 2 is interrupted.

  • Patent number: 8042532
    Abstract: A heat-cooking apparatus includes blowing means (100) that blows cooling air to an opening (20a) of a heating chamber (20) when a door (11) is opened after steam is supplied to the heating chamber (20) for preparatory operation before heat-cooking or for heat-cooking itself. More specifically, after steam is supplied to the heating chamber (20), when the door (11) is opened, the blowing means (100) drives a conventionally existing cooling fan (101) to suck in cooling air from outside the apparatus, and deflects the cooling air toward the opening (20a) of the heating chamber (20) with a decoration box (102) so that the cooling air is blown to the opening (20a) so as to pass sideways substantially across it. Thus, the cooling air mixes with high-temperature steam that tends to overflow frontward as soon as the door (11) is opened, and thereby lowers the temperature of the steam. This surely prevents the user from being hurt, as by being burnt, with the overflowing steam.

  • Patent number: 8028653
    Abstract: A filament post used in plasma-enhanced chemical vapor deposition has an outer shell and an inner post. An electrical potential is applied only to the inner post to ensure that there is no impact on the plasma density and the carbon film properties. The inner post and the outer shell are electrically insulated by ceramic insulators, such that no electrical potential is applied to outer shell. The stress generated in the carbon film is directly related to the electrical potential of the surface to which the film is deposited. The carbon film deposited on the outer shell of the post is not highly stressed, which significantly reduces film delamination from the filament post surfaces.
