  • Patent number: 11297694
    Abstract: A slide-in or drop-in cooking range includes an upper cooktop in the form of a module suspended above an oven cavity. For installation purposes, the upper cooktop can be vertically repositioned relative to the oven cavity to assure proper alignment with the countertop and avoid damage to the cooktop as a result of combined thermal and mechanical stresses over time. The disclosure is particularly applicable to ranges employing glass cooktops having a periphery designed to rest upon edge portions of a countertop and contemplates various mechanisms to perform the cooktop repositioning function, including select mechanisms for locking, ratcheting and biasing the cooktop to establish a desired vertical position for the cooktop.

  • Patent number: 6936793
    Abstract: A solder reflow oven with horizontal cyclonic convection air flow for enhancing equalized heating of printed circuit boards conveyed therethrough. Air circulation apparatus can include a first air movement fan for urging air to move horizontally laterally from the first side wall of the oven toward the second side wall of the oven across and above printed circuit boards being conveyed therethrough. A second air fan is positioned below and laterally displaced from the conveying means for directing a second air stream below the first air stream and oppositely oriented in order to urge movement of heated air across the undersurface of the conveyor for enhancing equalization of heating of the printed circuits boards thereupon. Preferably, both blowers are oriented to move air approximately perpendicularly with respect to the direction of movement of the conveyed printed circuit boards in opposite respective directions thereabove and therebelow.

  • Patent number: 6660980
    Abstract: A top plate is provided for use in a cooking device having an induction heater alone or an infrared heater in addition, which comprises a transparent crystallized glass plate, a light-shading film on a bottom surface of the glass plate and an ornamental film formed on the top surface of the glass plate. The light-shading film is a porous layer of inorganic pigment powder dispersed in glass matrix. The light-shading film has small apertures at a portion corresponding to the infrared heater. Alternatively, it has a decreased thickness at the portion. In another alternative, a luster film is used in place of the inorganic pigment layer at the portion corresponding to the infrared heater.

  • Publication number: 20030111456
    Abstract: A cooking appliance includes a grilling grate supported directly above at least one heating element and situated adjacent to a downdraft grill. The grilling grate includes structure to effectively shield the heating element(s) from an air flow generated during operation of the downdraft system. More specifically, the grilling grate includes a grilling surface on an upper side, and a plurality of conductive heat members on a lower side. The conductive heat members have side portions which extend about the heating element in order to cloak the heating element from the effects of the airflow produced by the downdraft system thereby providing a more efficient means of energy transfer to the grilling surface.

  • Publication number: 20020190055
    Abstract: An appliance control protection apparatus for a glass ceramic cooktop is constructed with a double wall housing and a low voltage cooling fan. The double wall housing is comprised of a first inner wall and a outer wall and prevents the transfer of heat from the heating elements in a glass ceramic cooktop towards the electronic control unit. The first inner wall is adhered to the underside of the ceramic glass panel of the cooktop and the outer wall snaps into position over the first wall, resulting in a space therebetween for insulation. Additionally, the control housing is provided with a low voltage fan that convects heat away from hot spots formed on the electronic control unit toward other components within the control housing. The low voltage fan operates in response to certain operating temperatures within the control housing as detected by a heat sensor.

  • Patent number: 6455819
    Abstract: The cooking apparatus has at least one cooking area including a glass-ceramic panel providing a cooking surface and at least one glass molded part made from glass with definite mechanical stability, such as technical glass or hardened glass. The glass molded part or parts act as an adapter for the glass-ceramic panel. In a preferred embodiment the glass-ceramic panel is bordered or enclosed by an assembly of the glass molded parts that form the adapter and protect the edges of the glass-ceramic panel. Some of the glass molded parts provide signaling and/or control panels, e.g. for residual heat. The glass molded parts replace prior art molded parts, such as eloxated aluminum and stainless steel parts, that are disadvantageously sensitive to direct mechanical surface loads.
