Embodiment Construction

[0043] figure 1 A cooking appliance 1 is shown in a schematic view. The cooking appliance 1 can be configured, for example, as an oven or steamer.

[0044] The cooking appliance 1 comprises a cooking chamber 2 for accommodating a cooking product, not shown. The cooking chamber 1 is delimited by a cooking chamber wall 3 . Part of the cooking chamber wall is usually a door, not shown. Food can be loaded into the cooking chamber through the door.

[0045] During cooking operation of the cooking appliance 1 , the cooking chamber 2 is heated by means of heating elements, not shown. Here, the cooking chamber wall 3 is sometimes hot and must be cooled. In addition to the cooking chamber wall 3 it may also be necessary to cool the electrical controls of the cooking chamber 1 , for example in the form of a control circuit board not shown.

[0046] In order to cool the cooking chamber wall 3 (and / or the control circuit board), a two-channel ventilation system 5 is arranged on the ou...

Abstract

The invention relates to a cooking device (1) comprising: a cooking chamber (2) for receiving food to be cooked, which cooking chamber is at least partially delimited by a cooking chamber wall (3); afan (10) for generating a cooling air stream for cooling an outer side (4) of the cooking chamber wall (3) with the result that an intake region (p-), in which there is a negative pressure in relationto the surrounding area (U), and a blow-out region (p+), in which there is excess pressure in relation to the surrounding area (U), are produced; a short-circuit device (23) for generating a short-circuit air flow (24) between the blow-out and intake region (p+, p-) and in this way generating a pressure-neutral region (pn); and a vapour outlet (16) in the cooking chamber wall (3) for dischargingvapours (17) from the cooking chamber (2) into the pressure-neutral region (pn).

Description

technical field [0001] The present invention relates to a cooking appliance. Background technique [0002] A cooking appliance, such as an oven or steamer, has a cooking chamber for holding food. A well-known requirement is to adjust the humidity in the cooking cabinet. [0003] The cause of humidity is water vapor. This water vapor is generated during cooking and comes out of the cooking item. Furthermore, certain cooking appliances such as steamers additionally supply water vapor to the cooking process. [0004] The requirement to be able to adjust the humidity in the cooking cabinet is based on different reasons. First, humidity affects energy consumption. The wetter it is, ie the less fresh air is introduced into the cooking chamber, the less energy is consumed. Excessive humidity, on the other hand, can have a negative effect on the service life of the cooking appliance. [0005] Different solutions are therefore known for adjusting the humidity in the cooking ch...
