Definitions
- the present invention relates to a method for heating a food or of food in a closed high-mounted cooking appliance with at least one cooking chamber delimiting muffle with a muffle opening, a - motorized or manually movable - bottom door for closing the muffle opening, and arranged on the bottom door Hob, as well as a high-installation cooking appliance.
- the present object is achieved by the method with the features of claim 1 and by the device according to claim 15.
- the method comprises the following steps: (a) depositing at least one food on the hob in an open state of the high setting cooker, without cookware such as pots, pans or the like,
- step (c) in addition by a hot air and / or radiant heat from other radiators, such as. B. a ring heater and / or a top heater, comes, heated.
- a hot air and / or radiant heat from other radiators such as. B. a ring heater and / or a top heater
- the hob heats up relatively quickly, while the hot air typically takes some time to increase the temperature in the oven significantly.
- This difference in the heating time the food lying on the hob is preheated quickly, z. B. thawed, and then - with now enough hot hot air - finished or cooked through. By doing so, an uneven cooking of food is avoided, and there are time savings, since, among other things, a preheating or separate thawing no longer needs to be necessary.
- a typical application example is the preparation of frozen pizza, which can be finished with this method without preheating in 10 minutes.

- the radiators can be operated alternately. If the hob is operated with a heating power of 15 - 20% of the total heating power, it is advantageous if the remaining heating power to a ring radiator and / or a top heater and / or a radiant heater, for.
- As a halogen lamp distributed. It is particularly favorable when the heating power of the ring heater about 25% of the total heating power and the heating power of the upper heat radiator is about 55-60%.
- the fan is operated to generate the hot air, in particular with maximum ventilation performance.
- a storage unit for storing Schnellgarprogrammen are present in the example Schnellgarprogramme for various common foods or types of food stored, and thus also be retrieved by the user.
- the fast cooking programs may differ, for example, in the operation of the hotplate in cost or bottom heat mode and / or in the relative heat output of the various heating elements to each other and / or the duration.
- the Schnellgarprogramme are user adjustable, z. B. the temperature or heating time is adjustable to adapt the heating operation to the individual taste of the user.
- the settings can be reset to factory settings, which then, for example, in a non-volatile memory, eg. A (EE) PROM, or even a non-volatile memory, e.g. As a ROM, can be stored.
- a non-volatile memory eg. A (EE) PROM
- a non-volatile memory e.g. As a ROM
