[0020] FIG. 2 shows the heating appliance from FIG. 1 without its housing, showing the guide means for guiding the bulkhead.

[0021] FIG. 3 is a perspective view of a preferred embodiment of the heating appliance from FIG. 1, with housing but without bulkhead.

DETAILED DESCRIPTION

[0022] FIGS. 1 to 3 show a preferred embodiment of the heating appliance 11 according to the invention. The heating appliance 11 is explained below using an oven, in particular a baking oven, as an example In principle, however, the invention could also be used in a steamer or a microwave, although with a microwave there is no need to retain hot air, but the invention rather focuses on the easier removal of the product support.

[0023] As FIG. 1 shows in particular, the heating appliance 11 has a housing 12, which in the case of a baking oven could also be described as a muffle or baking muffle. As a rule and in the embodiment described here, the housing 12 is rectangular or cuboid in design. It is made of a heat-resistant material, in particular a steel material.

[0024] The housing 12 encloses a heatable interior 13 bounded at the rear by a rear wall 14 and at the front by a door 15. In the illustrated embodiment, the door 15 is an oven hatch which blocks access to the interior 13 in the closed position. The housing 12 further comprises to opposite side walls 16a, 16b, a floor 17 and a ceiling wall 18 located opposite thereof.

[0025] At least one product support 19 for product to be heated is accommodated in the housing 12. By way of example, the product support 19 is shown in the form of a baking sheet having a support section 20 and a raised edge section 21 extending around the support section 20.

[0026] In the interior 13 of the housing 12, there is located a bulkhead 22, which is movably guided by guide means 23 between an operating position 24 located in the region of the rear wall 14 and a closed position 26, in which it is pulled out into the region of the housing opening 25 and closes the housing opening 25 substantially completely.

[0027] As FIGS. 1 and 2 show in particular, the bulkhead 22 is plate-shaped and likewise consists of a steel material.

[0028] The bulkhead 22 has a rectangular shape and closes the likewise rectangular housing opening 25 virtually completely in the closed position 26, as a result of which the interior 13 now lying behind the bulkhead 22 in the closed position 26 can immediately be brought up to temperature.

[0029] As mentioned above, the bulkhead 22 is movably guided by guide means 23 between the operating position 24 and the closed position.

[0030] As FIG. 2 shows in particular, the guide means 23 are designed such that they are secured to the rear wall 14 on the one hand and to the bulkhead 22 on the other hand. There is no contact with the side walls 16a, 16b.

[0031] As FIG. 2 shows in particular, the guide means 23 comprise two guide units 27a, 27b, each of which is, at a mutual transverse distance, joined to the housing 12 on the one hand and to the bulkhead 22 on the other hand.

[0032] Each of the guide units 27a, 27b has a guide linkage 29a, 29b consisting of several guide arms 28a, 28b, which is movable in the manner of an accordion while guiding the bulkhead 22 between the operating position 24 and the closed position 26.

[0033] As FIG. 2 shows in particular, the guide arms 28a, 28b are designed as pivotably connected swivel arms.

[0034] Each of the guide linkages 29a, 29b has two swivel arms, of which a first is pivotably mounted about a housing-side first pivot axis 30a and a second is pivotably mounted about a product support-side second pivot axis 30b, the two pivot axes being pivotably connected to each other via a third pivot axis 30c.

[0035] The guide means 23 are further provided with a synchronisation device (not shown) for synchronising the movement of the guide units 27a, 27b during the travel of the product support 19 coupled to the guide units 27a, 27b by way of the bulkhead 22.

[0036] As mentioned above, the bulkhead 22 is coupled to the at least one product support 19 in the form of the baking sheet by coupling means 31 in such a way that the bulkhead 22 can be moved from the operating into the closed position 26 by pulling out the product support 19.

[0037] The coupling means 31 comprise two hook elements 32a, 32b on the product support 19 and associated hook holders 33a, 33b on the bulkhead 22 for releasably holding the hook elements 32a, 32b.

[0038] As FIG. 3 shows in particular, the hook elements 32a, 32b are secured to the edge section 21 of the baking sheet and projects towards the rear therefrom.

[0039] On the bulkhead 22 there are located two hook holders 33a, 33b, which lie in the region of the outer edge sides and each of which has hang-in members 34 located on top of one another in the vertical direction of the bulkhead 22 for hanging in the associated hook elements 32a, 32b at the baking sheet.

[0040] As FIG. 2 shows in particular, the hang-in members 34 are designed as pins or bolts and located in holder slots 34a, 34b belonging to the hook holders 33a, 33b and extending in the vertical direction of the bulkhead 22, occupying the slot width of the associated holder slot 34a, 34b.

[0041] In the illustrated embodiment, there are therefore provided in the region of the two side walls of the bulkhead 22 holder slots 35a, 35b, in which are located three hang-in members 34 arranged on top of one another, in particular with regular spacing. As a result, the baking sheet can be placed at different heights on the bulkhead, depending on the selection of hang-in members 34.

[0042] As FIG. 2 shows in particular, at least one ventilation hole 36, in particular a pattern formed from several ventilation holes, is formed on the bulkhead 22 for ventilating and venting the interior 13 of the housing 12.

[0043] During the operation of the oven, the door 15 is closed and the bulkhead 22 is in its operating position 24 in the region of the rear wall 14 of the housing 12. The interior 13 is heated to a suitable temperature, so that cooking products on the baking sheets, grids or the like are heated to a corresponding temperature. At the end of the cooking process, the door 15 or oven hatch is opened, and the baking sheet can be pulled out of the housing 12 manually, but in contrast to conventional ovens, it is not yet removed from the housing 12, but the extraction of the baking sheet causes a displacement of the bulkhead 22 from the operating position 24 into the closed position 26, in which the housing opening 25 is substantially closed completely by the bulkhead 22. The baking sheet is now substantially completely outside the housing 12, but is still located on the bulkhead 22. The bulkhead 22 screens the interior of the housing 12, so that it can quickly be brought up to temperature again. The baking sheet can be removed from the bulkhead 22 by disengaging the hook elements from the associated hang-in members 34 on the bulkhead 22, but it can also be gripped at the sides, thereby avoiding an unfavourable slant of the support section of the baking sheet, which may be covered by liquid such as gravy.
