Abstract: A method and apparatus for baking food in a closed cooking space in which heated air is circulated. The temperature of this heated air is varied in a sawtooth fashion about a predetermined mean temperature value by generating a plurality of sequential heat radiation pulses, by means of electric air heaters or the like, of a predetermined amplitude, frequency, and duration for baking the food with a minimum of soiling of the cooking space.

Abstract: A flush-in device for accommodating agents for washing or rinsing can be used in an appliance such as a washing machine, dishwasher and the like equipped with a vessel for washing or rinsing. The flush-in device includes a plurality of chambers arranged one adjacent the other for receiving different agents therein. An outlet structure common to all of the chambers is provided and leads to the above-mentioned vessel. A plurality of water inlet stubs corresponding to respective ones of the chambers are disposed at one location of the flush-in device and a plurality of channel-like water conduits connect respective ones of the stubs to corresponding ones of the chambers.

Abstract: A cooking tray is disclosed in which a carrier of tempered glass is mounted on a support surface between the support surface and the heating element. The carrier is insulated to protect it from the heat of the heating element by thermal sealing means comprising in one embodiment an intermediate ring surrounding the heating element having a layer of insulation attached to the intermediate ring. Moisture seals are also provided between the carrier and the heating element to prevent moisture from entering between the carrier and the heating element.Various alternative embodiments illustrating the concept of utilizing the carrier of tempered glass with an intermediate ring, heat insulation and moisture sealing means to permit the combination of various heating elements with a carrier of tempered glass are disclosed.
