Description

The invention relates to an air passage, in particular for mounting in a wall opening or recess, which are formed in a wall. It also relates to a wall which has such an air passage and a furnace which has such an air passage.

Heating devices, in particular ovens, are known, in the walls of which openings are made. The wall openings can be used to supply air from the environment into the heating device or to remove air from the heating device. Stoves can have brick walls. A wall opening is often provided above the combustion chamber, through which air which has been heated in the furnace can escape to the surroundings - this is generally the space in which the furnace is located. Ventilation grilles are known for covering the wall openings. On the one hand, the ventilation grille secures the wall opening against unauthorized interventions, on the other hand, the ventilation grille also allows regulation of the heat emission to the environment.

Out DE 20 2010 001 764 U1 a ventilation grille is known which can be introduced at wall openings of stoves. The ventilation grille has a frame in which an opening is formed in the center. The opening can be closed and opened with six parallel, strip-shaped flaps. The flaps can be adjusted by means of a swivel lever such that the adjustment of one flap causes the adjustment of all other flaps. Clamps are attached to the back of the frame, which should allow the ventilation grille to be clamped in the wall opening by means of springs. The flaps also prevent access through the opening of the ventilation grille. Covering a wall opening of a stove with ventilation grilles that have strip-shaped flaps does not, or at least not completely, meet today's aesthetic expectations. At least the flaps are on the outside of the Wall opening over. In addition, the known ventilation grille cannot be arranged at corners between walls, since it is necessary to insert the frame into the wall such that it is completely surrounded by the wall in relation to its circumferential direction.

The object of the invention is to eliminate the disadvantages of the prior art. In particular, an air passage is to be specified that does not require flaps and yet prevents passage and, in particular, can also be arranged at corners between adjoining walls.

This object is solved by the features of claims 1, 14 and 15. Appropriate configurations of the inventions result from the features of the subclaims.

In the Fig. 1 The first embodiment of an air outlet 1 according to the invention shown has a housing 2 which has a front side 3, a rear side 4, an underside 5, an upper side 6 and two end faces 7, 8. Pages 3 to 8 face away from interior 9.

The front 3 of the housing 2 is formed by the front wall 11. In the first embodiment, which is an example of the first variant, the rear side 4 of the housing is formed by the first air passage opening 21. The two end faces 7, 8 are formed by two end walls 13, 14. The underside 5 of the housing is formed by the first wall 15, which is referred to below as the bottom 15.1. The upper side 6 of the housing 2 is formed by the second wall 16, which is referred to below as the ceiling 16.1, and the second air passage opening 22. The second air passage opening 22 is formed between the ceiling 16.1 and the front wall 11. The second air passage opening extends from a front edge 16a of the ceiling 16.1, which faces the front wall 11, in the direction of the front wall 11. The second wall 16 thus does not extend to the front wall 11, so that the interior space 9 extends between the first and second air passage opening 21, 22 extends.

The first wall 15, the second wall 16 and the second air passage opening 22 are arranged horizontally. The front wall 11, the end walls 13, 14 and the second air passage opening 22 are arranged vertically. The two air openings each extend from one end wall 13 to the other end wall 14. The first embodiment is a straight strip.

In Fig. 6a is a schematic sectional view of the in Fig. 1 shown first embodiment shown. The first embodiment is in the first position, that is, the first wall 15 is its floor 15.1, while the second wall is its ceiling 16.1. It can be seen that, at the first air passage opening 21, air can enter laterally into the interior 9 of the housing 2 and can emerge from the interior 9 upwards through the second air passage opening 22 (arrow A). It is alternatively possible for air to enter the interior 9 of the housing 2 from above at the second air passage opening 22 and to exit laterally through the first air passage opening 21 from the interior 9 (opposite direction to arrow A).

In the Fig. 6b The embodiment shown corresponds to that in Fig. 6a Embodiment shown, except that the second wall 16 forms the floor 16.2 and the first wall 15 the ceiling 15.2. This is the in Fig. 6b shown embodiment in the second layer. It is in Fig. 6b It can be seen that air can enter the interior 9 of the housing 2 from below at the first air passage opening 21 and can escape laterally from the interior 9 through the second air passage opening 22 (arrow B). It is alternatively possible for air to enter laterally into the interior 9 of the housing 2 at the second air passage opening 22 and to exit from the interior 9 downward through the first air passage opening 21 (opposite direction to arrow B).

The in the Figures 6a and 6b The first and second layers shown can both be compared to those shown in Fig. 1 shown first embodiment can be realized. For this purpose, the first embodiment can be turned through 180 ° on a plane of Fig. 6a horizontal axis of rotation are rotated such that the first wall 15 is at the top and the second wall 16 is at the bottom.

At the in Fig. 1 First embodiment shown air enters laterally into the interior 9 of the housing 2 at the first air passage opening 21 (arrow A1) and emerges from the interior 9 upwards through the second air passage opening 22 (arrow A2). However, the air can also be conducted in the opposite direction, ie it enters the interior 9 of the housing 2 from above at the second air passage opening 22 (opposite direction to arrow A1) and exits laterally from the interior 9 through the first air passage opening 21 ( opposite direction to arrow A2).

In the Fig. 1 The first embodiment shown has additional stiffening elements which are arranged in the interior 9 of the housing 2. The stiffening elements are walls 17 which connect the first wall 15, the second wall 16 and the front wall 11 to one another. They can extend over the entire height and / or width of the housing 2. They are formed at a distance from the end walls 13, 14. The interior is divided into chambers by means of the walls 17. The chambers can adjoin each other horizontally.

The outside of the front wall 11, when the air passage 1 is arranged in or on a wall, is visible when looking at the wall. It can therefore wear a layer of plaster. For this purpose, a layer of a cleaning material 18 can be applied to the outside of the front wall. A plaster-holding material 18 can also be applied to the outside of the second wall.

The in the Figures 2 and 3 The second embodiment shown corresponds to the first embodiment, except that the housing 2 has a first leg 31 and a second leg 32. The second leg 32 extends at an angle α of 90 ° to the first leg 31.

The first leg 31 has an outer side 311 and an inner side 312. Likewise, the second leg 32 has an outside 321 and an inside 322. The two outer sides 311, 321 form the outer corner 33 of the housing 2, while the two inner sides 312, 322 form the inner corner 34 of the housing 2. The front wall 11 is formed on the outer sides 311, 321, and the first air passage opening 21 is formed on the inner sides 312, 322. The front of the second embodiment is thus formed by the outer sides 311, 321 of the housing 2

The first leg 31 and the second leg 32 have essentially the same structure as that in FIG Fig. 1 Embodiment shown, wherein at the interface at which the first leg 31 borders the second leg 32, no end wall, but a stiffening element - in the second embodiment, this is a wall 17 - is formed. The interface is a plane, for example a vertical plane, between the inner corner 34 and the outer corner 33.

It in the Figures 2 and 3 It can be seen that the front wall 11 has a first section 11 ', which forms the outside 311 of the first leg 31, and a second section 11 ", which forms the outside 321 of the second leg 32. Both sections 11', 11" of the Front wall 11 can be plastered and, for this purpose, each carry a layer of cleaning material 18. The second embodiment represents an outer corner. It can therefore be arranged as an outer corner in a wall opening or recess in a wall of a heating device, preferably on an outer corner of the wall.

Like the front wall 11, the first wall 15 and the second wall 16 each have a first section, which delimits the first section 9 ′ of the interior 9 located in the first leg 31, and each have a second section, that located in the second leg 32 second section 9 "of the interior 9. The first air passage opening 21 also has a first section which adjoins the first section 9 'of the interior 9 and a second section which adjoins the second section 9" of the interior 9. In addition, the second air passage opening 22 has a first section which adjoins the first section 9 ′ of the interior 9 and a second section which adjoins the second section 9 ″ of the interior 9. The first sections are by an upper line added to the reference number, the second sections are identified by two upper lines added to the reference number.

In the Fig. 4 The third embodiment shown corresponds to the second embodiment, except that the first air passage opening is formed on the outer sides 311, 321 and that the front wall 11 is formed on the inner sides 312, 322. The third embodiment represents an inner corner of the air outlet according to the invention. It can therefore be arranged as an inner corner in a wall opening or recess in a wall of a heating device, preferably on an inner corner of the wall. The front of the third embodiment is thus formed by the inner sides 312, 322 of the housing 2

Fig. 5 shows an oven 101 having walls 102, 103, 104. Wall 103 is angled away from wall 102 to form an outer corner. Wall 104 is angled away from wall 103 to form an inner corner. It is in Fig. 5 to recognize that air passages 1 according to the first embodiment 1a, the second embodiment 1b and the third embodiment 1c are arranged on the walls 102, 103, 104. In the first position, these air passages 1a, 1b, 1c are arranged on the upper edge 105 of the walls 102, 103, 104. In their second position, they are arranged on the lower edge 106 of the walls 102, 103, 104. It can be seen that air outlets according to the invention can form both inside and outside corners.

The air inlets 1 located on the lower edge 106 enable cold air to be supplied from the space 107, in which the furnace 101 with its walls 102, 103, 104 is located, into an interior of the furnace 101 Fig. 6b is shown at the first air passage opening 21 air from below into the interior 9 of the housing 2 and out of the interior 9 through the second air passage opening 22.

The air inlets 1a, 1b, 1c located on the upper edge 105 allow warm air to escape from an interior of the furnace into the space 107 Fig. 6a is shown at the first air passage opening 21 air laterally in the interior 9 of the housing 2 in and out of the interior 9 up through the second air passage opening 22.

In Fig. 5 the front sides 11 of the air passages 1 are shown as black areas. This is to make it easier to see. However, the front can have a layer of plaster. This plaster layer can have the same color as the plaster layer applied to the furnace walls 102, 103, 104.

The in the Figures 7 to 9 The fourth embodiment of an air outlet 1 according to the invention shown has a housing 2 which has a front side 3, a rear side 4, an underside 5, an upper side 6 and two end faces 7, 8. Pages 3 to 8 face away from interior 9.

The front 3 of the housing 2 is formed by the front wall 11. In the fourth embodiment, which is an example of the second variant, the rear side 4 of the housing is formed by the first air passage opening 21 and the rear wall 12. The two end faces 7, 8 are formed by two end walls 13, 14. The underside 5 of the housing is formed by the first wall 15, which is referred to below as the bottom 15.1. The top 6 of the housing 2 is formed by the second wall 16, which is referred to below as the ceiling 16.1, and the second air passage opening 22. The second air passage opening 22 is formed between the rear wall 12 and the front wall 11. The second air passage opening 22 extends from an edge 12a of the rear wall 12, which faces away from the first wall 15, in the direction of the edge 11a of the front wall 11, which faces away from the first wall 15. The edges 11a and 12a are in alignment with one another.

The first air passage opening 21 extends from an edge of the first wall 15 to a first edge 16b of the second wall 16. The rear wall 12 borders with an edge 12b on a second edge 16a of the second wall 16. The second wall 16 does not extend to the front wall 11, so that the interior 9 extends between the first and second air passage openings 21, 22. Due to the formation of the rear wall 12 on the second edge 16a of the second wall 16, the rear wall 12 is arranged offset in the direction of the front wall 11 to the edge 16b of the second wall 16. For this reason, a step is formed in each of the end walls 13, 14. The end faces 13, 14 connect the first wall 15, the front wall 11 and the rear wall 12 to one another.

The first wall 15, the second wall 16 and the second air passage opening 22 are arranged horizontally. The front wall 11, the rear wall 12, the end walls 13, 14 and the second air passage opening 22 are arranged vertically. The two air passage openings 21, 22 each extend from one end wall 13 to the other end wall 14. The fourth embodiment is a straight strip.

The second air passage opening 22 is covered with a cover 19. The cover 19 has openings 20 through which air can pass. In the Figures 7 to 9 It can be seen that one layer of a cleaning material 18 is applied to the outside of the front wall 11 and another layer of a cleaning material 18 is applied to the outside of the second wall 16.

The fourth embodiment additionally has stiffening elements which are arranged in the interior 9 of the housing 2. The stiffening elements are walls 17 which connect the first wall 15, the second wall 16, the front wall 11 and the rear wall 12 to one another. They can extend over the entire height and / or width of the housing 2. They are formed at a distance from the end walls 13, 14. The interior is divided into chambers by means of the walls 17. The chambers can adjoin each other horizontally.

In Fig. 6c is a schematic sectional view of the in the Figures 7 to 9 shown fourth embodiment shown. The fourth embodiment is in the first position, that is, the first wall 15 is its floor 15.1, while the second wall is its ceiling 16.1. It can be seen that air enters laterally into the interior 9 of the housing 2 at the first air passage opening 21 and can emerge from the interior 9 upwards through the second air passage opening 22 (arrow C). It is alternatively possible for air to enter the interior 9 of the housing 2 from above at the second air passage opening 22 and to exit laterally through the first air passage opening 21 from the interior 9 (opposite direction to arrow C).

In the Fig. 6d The embodiment shown corresponds to that in Fig. 6a Embodiment shown, except that the second wall 16 forms the floor 16.2 and the first wall 15 the ceiling 15.2. This is the in Fig. 6d shown embodiment in the second layer. It is in Fig. 6d It can be seen that at the first air passage opening 21, air can enter the interior 9 of the housing 2 from below and can escape laterally from the interior 9 through the second air passage opening 22 (arrow D). Alternatively, it is possible for air to enter laterally into the interior 9 of the housing 2 at the second air passage opening 22 and to exit from the interior 9 downward through the first air passage opening 21 (opposite direction to arrow D).

The in the Figures 6c and 6d The first and second layers shown can both be compared to those shown in Figures 7 to 9 fourth embodiment shown can be realized. For this purpose, the fourth embodiment can be turned through 180 ° on a plane of Fig. 6c horizontal rotation axis are rotated such that the first wall 15 is above and the second wall 16 is below.

In the in the Figures 7 to 9 Fourth embodiment shown, air enters laterally into the interior 9 of the housing 2 at the first air passage opening 21 (arrow C1) and emerges from the interior 9 upwards through the second air passage opening 22 (arrow C2). However, the air can also be conducted in the opposite direction, ie it enters the interior 9 of the housing 2 from above at the second air passage opening 22 (opposite direction to arrow C1) and exits laterally from the interior 9 through the first air passage opening 21 ( opposite direction to arrow C2).

The in the Figures 10 to 12 The fifth embodiment shown corresponds to the fourth embodiment, except that the housing 2 has a first leg 31 and a second leg 32. The second leg 32 extends at an angle α of 90 ° to the first leg 31.

The first leg 31 has an outer side 311 and an inner side 312. Likewise, the second leg 32 has an outside 321 and an inside 322. The two outer sides 311, 321 form the outer corner 33 of the housing 2, while the two inner sides 312, 322 form the inner corner 34 of the housing 2. The front wall 11 is formed on the outer sides 311, 321, and the first air passage opening 21 is formed on the inner sides 312, 322. The front of the fifth embodiment is thus formed by the outer sides 311, 321 of the housing 2

The first leg 31 and the second leg 33 have essentially the same structure as that in FIGS Figures 7 to 9 Embodiment shown, wherein no end wall is formed at the interface at which the first leg 31 borders the second leg 32. The interface is a plane, for example a vertical plane, between the inner corner 34 and the outer corner 33.

It in the Figures 10 to 12 can be seen that the front wall 11 has a first section 11 ', which forms the outside 311 of the first leg 31, and a second section 11 ", which forms the outside 321 of the second leg 21. Both sections 11', 11" of the Front wall 11 can be plastered and, for this purpose, each carry a layer of cleaning material 18. The fifth embodiment represents an outer corner. It can therefore be arranged as an outer corner in a wall opening or recess in a wall of a heating device, preferably on an outer corner of the wall. Stiffening elements in the form of walls 17 are formed in both the first leg 31 and the second leg 32.

Like the front wall 11, the rear wall 12, the first wall 15, the second wall 16 and the cover 19 each have a first section, which delimits the first section 9 ′ of the interior 9 located in the first leg 31, and each have a second section which delimits the second section 9 ″ of the interior 9 located in the second leg 32. The first air passage opening 21 also has a first section which adjoins the first section 9 ′ of the interior 9 and a second section which adjoins the second section 9 "of the interior 9 adjoins. In addition, the second air passage opening 22 has a first section which adjoins the first section 9 ′ of the interior 9 and a second section which adjoins the second section 9 ″ of the interior 9. The first sections are indicated by a reference numeral Upper line, the second sections are identified by two upper lines added to the reference symbol.

The in the Figures 13 to 15 The sixth embodiment shown corresponds to the fifth embodiment, except that the first air passage opening is formed on the outer sides 311, 321 and that the front wall 11 is formed on the inner sides 312, 322. The sixth embodiment represents an inner corner. It can therefore be arranged as an inner corner in a wall opening or recess in a wall of a heating device, preferably on an inner corner of the wall. The front side 11 of the sixth embodiment is thus formed by the inner sides 312, 322 of the housing 2.
