    Description


    [0001] The present invention relates to an oven, in particular a domestic pyrolytic oven which has a ventilation unit for expelling radiant heat to an outside. In a conventional oven, during a cooking/baking process an inner lining of the cooking/baking chamber is generally spoiled with food residues. The cleaning of the hardened food residues is usually very laborious. In a conventional oven having a pyrolytic mode, the food residues are burned off by heating the chamber up to temperatures above 500 °C. In general, in a conventional pyrolytic oven the inner lining of the chamber has a smooth surface. Thereby, the food residues easily peel off during the pyrolysis. After the chamber has sufficiently cooled down, the user can easily collect the ashes from the bottom of the chamber. Thus, the pyrolytic mode greatly facilitates cleaning of the cooking/baking chamber.
    In the conventional pyrolytic oven the high temperatures prevailing inside the chamber during the pyrolytic mode poses a risk to the thermally sensitive component parts of the oven, in particular the electrical components which generally have a relatively low limit temperature. Also, the hot component parts of the oven which are exposed to an outside pose a severe risk to the health of the user. In particular these hot component parts can cause skin burns and scalding.
    US2010/0276412 A1 discloses a cooking range which has a controller with a pyrolytic mode. This cooking range has an air circulation mechanism which expels the heat to an environment in order to reduce an amount of heat transmitted to the controller.

    [0002] US 4 601 279 discloses an oven comprising a heat protective shield which is arranged through an air gap above a ventilation unit. The heat protective shield has a size and shape configured to screen a user interface and electrical components from radiant heat emanated from hot air inside the ventilation unit and a chamber during operation. The heat protective shield comprises a mounting plate. The electrical components are attached onto an upper surface of the mounting plate which is averted from the ventilation unit.

    [0003] EP 2 107 317 A2 discloses an oven with a dividing plate which reinforces an upper wall of an outer case of the oven from below. The dividing plate is connected to supporting portions which are fixed to an upper plate.

    [0004] A problem with the conventional pyrolytic cooking range is that if the air circulation mechanism is shut off, or fails to operate, then the electrical parts such as the controller are excessively heated and get rapidly aged and eventually damaged. On the other hand, in case the air circulation mechanism is continually operated the overall energy consumption of the oven increases.
    An objective of the present invention is to provide an oven which
    overcomes the aforementioned drawbacks of the prior art in a cost-effective way and which enables an energy-efficient and effective ventilation of the critical component parts and a reliable protection of the electrical components from heat.

    [0005] This objective has been achieved by the oven as defined in claim 1. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.

    [0006] The oven of the present invention comprises a heat protective shield which is arranged through an air gap above a ventilation unit which expels the radiant heat to an outside. The heat protective shield has a size and shape which is configured to screen the user interface and electrical components from the radiant heat emanated from the hot air inside the ventilation unit and the chamber during operation. The heat protective shield has a mounting plate. The electrical components are attached onto an upper surface of the mounting plate which is averted from ventilation unit.

    [0007] The heat protective shield comprises a mounting bracket which is attached across the side walls so as to reinforce the entire ceiling of outer case from below.

    [0008] In another embodiment, the heat protective shield comprises a throughlet for installing cables which lead to the electrical components.

    [0009] The heat protective shield comprises a vertical partition plate which physically divides a region above the ventilation unit into two separate sub regions, namely a first sub region including the electrical components, and a second sub region which is close to the fan. Thereby, it is safeguarded that a temperature in the first sub region is always lower than the temperature in the second sub region during an operation of the oven.

    [0010] In another embodiment, the ventilation unit has a duct and a fan inside the duct. The ventilation unit draws air from an interior of the door and from the chamber into the duct, and discharges the air inside the duct to the outside via an outlet formed underneath the control panel.

    [0011] In another embodiment, the duct is partitioned into two sections one above the other. The lower section draws air from an interior of the door and from the chamber into the duct. The upper section discharges the air in the duct to the outside. The fan is arranged between the two sections.

    [0012] With the heat protective shield of the present invention, the electrical components can be easily secured to their designated location and effectively protected from the radiant heat. The heat protective shield of the present invention can be easily mounted to its position by means of its mounting bracket. By the heat protective shield of the present invention the cables which lead to the electrical components can be easily installed by means of the throughlet. The heat protective shield of the present invention ensures by means of the partition plate that the sub region including the electrical components is relatively colder than the sub region close to the fan. The ventilation unit of the present invention ventilates the components parts exposed to an outside, in particular the door, and thus, protects the user from skin burns. By the ventilation unit of the present invention, the hot air and food residues are prevented from diffusing into a space between an outer case and an inner case even when the fan is shut off. Also by the stacked sections, the ventilation performance has been improved.

    [0013] Additional advantages of the oven of the present invention will become apparent with the detailed description of the embodiments with reference to the accompanying drawings in which:
