Abstract

The submitted invention refers to an oven with a system for cooling oven doors (1) featuring at least two glass surfaces, more precisely an external glass (2), located on the external side of oven looking towards the user and an internal glass (3) on the internal side of the oven, where the specified doors (1) in the closed position are tightly fitting the front wall (4) of then oven. The main feature of the invention is that the front wall (4) of the oven in the area above the upper door (1) wall (5) is designed to feature a series of ventilation openings (10, 11, 12) and that the door is designed to feature ventilation openings (13, 14) leading to the area in- between among the specified glass surfaces (2, 3) of the door (1). The cold air current runs from the interior of the oven through the ventilation openings (10, 11, 12) and further on to the ventilation openings (13, 14) as well as the space between the two glass surfaces (2, 3) of the door (1) into the environment.

Description

Oven with oven door cooling system

The present invention relates to the field of household appliances, and more specifically to the field of ovens, and within the scope thereof, to the cooling of the oven door.

Publication of European Patent No. EP 1 382 913 Al is a known oven comprising a closed housing with a door and a first and second air ducts. In this case, the first duct extends at least above the oven as well as above the door and extends there to the outside, where the first air flow created by the fan leads. The second duct runs along the interior of the front window glass and flows into the first duct, leading to the upward directed second airflow that the first airflow sucks into the surroundings. The first inclined plane is positioned on the oven door, which rises from the oven direction towards the outside until the entrance of the second channel into the first channel. The inclined plane at its highest point narrows the first channel and exceeds the height of the front glass of the oven door.

The disadvantage of this known solution lies in the fact that during the cooling of the oven door, the flow of clean cooling air and the flow of air mixed with gases and steam are sucked out of the oven.

It is an object of the present invention to provide an oven which will eliminate the disadvantages of the known solutions for cooling the oven door.

The task of the invention is solved by the fact that the front wall of the oven in the area above the upper side of the door is designed with a series of ventilation openings through which the flow of cooling air and the flow of air mixed with gases and vapors from the oven. In this case, the door of the oven in the area of its upper side is, by its entire thickness, designed with at least one projection raised above said upper side.

According to the invention, there is a reference to a bulge on the side facing the front wall of the oven, designed with a ventilation opening leading to an intermediate space between said glass doors of the oven. The central ventilation opening of said set of ventilation openings lies in the area between the said projections of the oven door, while the respective lateral ventilation opening of said set of ventilation openings lies opposite the respective projection of the door. The aforementioned ventilation opening, designed in each bulge, is aligned with the respective lateral vent in the front wall of the door.

The invention will now be described in more detail with reference to an embodiment and with reference to the accompanying drawings, in which FIG. 1 is an oven door according to the invention when viewed from the inside of the oven; FIG. 2 is a cross-sectional view of the oven according to the invention in line II-II; 3 is a cross-sectional view of the oven door according to the line III-III.

The oven according to the invention comprises a door 1 with at least two windows, namely an external glass 2 lying on the outside facing the user side of the oven and an inner glass 3 lying on the inside of the oven, said door 1 being closed tightly adjacent to front wall 4 ovens. In the area of its upper side 5, the door 1 is, in its entire thickness, formed by at least one projection, preferably by two projections 6, 7, which are raised above said upper side 5 of the door 1 and arranged in the area of the respective vertical edge 8, 9 of the door 1 The front wall 4 of the oven in the area above the upper side 5 of the door 1 is designed with a central vent 10 and lateral vents 11, 12, with the central vent 10 in the area between said projections 6, 7, while the respective side vents the opening 11, 12 directly opposite the respective protrusion 6, 7 of the door 1. The respective protrusion 6, 7 is on the side facing the front wall 4 of the oven, designed with a ventilation opening 13, 14 leading to the space between said glasses 2, 3 of the door 1 , wherein said respective ventilation opening 13, 14 is aligned with the respective lateral ventilation opening 11, 12 in the front wall 4 of the door 1.

The oven door cooling according to the invention is as follows. Assembly for transporting cooling air and suction of air mixed with gases and vapors from a furnace, which is not described in detail here, as it is the subject of a second patent application, pushes the flow of air mixed with gases and vapors from a furnace through a central vent 10 front wall 4 ovens and from there into the surrounding area. On the other hand, said assembly for transporting cooling air and suction of air mixed with gases and vapors from the oven space pushes the flow of cooling air through the side vents 11, 12 in the front wall 4 of the oven, where through said ventilation openings 13, 14 are designed in the projections 6, 7 on the upper side 5 of the door 1 of the oven, it enters the space between said glasses 2, 3 of the door 1.

The flow of cooling air flows along said glasses 2, 3 of the door 1 downwards and exits through the open hole at the lower edge of door 1 into the surroundings. In this way, optimal cooling of the glass 2, 3 door 1 of the oven is achieved and prevents the user from getting burned on too hot glass. It is further achieved according to the invention that the flow of pure cooling air and the flow of air mixed with gases and vapors which are sucked out of the oven space do not interconnect
