Definitions
- the invention relates to a refrigeration device with a heat-insulating housing and at least one heat-insulating door attached to it, the door and the housing having an outer cladding, an inner cladding and a heat insulation layer produced between them by foaming, in which vacuum insulation panels are provided on the door and / or on the housing are introduced.
- vacuum insulation panels are assigned to the heat insulation side of the inner lining of the door and / or the housing and in that means are provided which at least approximately adapt the surface shapes at the location of the inner lining to the surface shapes of the vacuum insulation panels.
- the degree of coverage is significantly increased in comparison with the exterior cladding, particularly in the case of a refrigeration appliance housing, which improves the efficiency of the heat insulation and, as a result, significantly reduces the energy consumption of a refrigeration appliance is.
- Manufacturing is simplified by the remote arrangement of the vacuum insulation panels on the inner cladding, resulting from their by no means flat surface, for example caused by the shaping of support aids such as support strips for holding refrigerated goods shelves or evaporator shelves or also by the shaping of a condensate drain the refrigerator housing and refrigerator doors considerably, since on the one hand no manufacturing measures to prevent warping on their outer cladding are to be taken. On the other hand, positioning measures to ensure minimum distances between the vacuum insulation panels and the outer and inner cladding are also unnecessary in order to ensure that the gaps created by the vacuum insulation panels are completely foamed.
- the positionally accurate attachment of the vacuum insulation panels within the space filled with heat insulation material between the inner and outer cladding is particularly simple, especially for large-scale production, if, according to a preferred embodiment of the object of the invention, it is provided that the means are arranged on the vacuum insulation panels.
- the simple assembly results from the fact that when the vacuum insulation panels are attached to the inner cladding, no additional adaptation measures for them have to be taken to the surface shapes of the inner cladding.
- the means are designed as an at least approximately heat-insulating intermediate layer between the assignment location on the inner lining and the vacuum insulation panels.
- the intermediate layer that compensates for the surface shapes on the inner lining, it is possible to form the vacuum insulation panels even at the interface to the intermediate layer, as a result of which the vacuum insulation panels are designed to be flat on both sides and are therefore particularly easy to produce.
- the intermediate layers create the possibility of essentially restricting oneself to one type of vacuum insulation panel, since, due to the corresponding shaping of the intermediate layers Adaptation to different surface structures of the interior panels is possible.
- the intermediate layers thus result in a kind of standardization for the vacuum insulation panels, which means that
- the intermediate layer is produced by a separate molded part which serves as a coupling element between the vacuum insulation panels and the inner lining.
- the intermediate layer is formed by a heat insulation foam applied to the inner lining in liquid form, onto which the vacuum insulation panels are placed in the still liquid state.
- the vacuum insulation panels have at least one side which, in terms of its surface shape, is at least approximately matched to the surface shape of the assignment location on the inner lining. Due to the direct adaptation of the vacuum insulation panels to the surface shapes of the interior paneling, they can be quickly and precisely attached to the interior paneling in a precise, barrier-free manner.
- the surface shape of the vacuum insulation panels is produced by non-cutting shaping of their support bodies formed from glass fiber or silica or aerogels.
- support bodies formed from glass fiber, silica or aerogels their adaptation to the surface shape of the interior lining by non-cutting shaping is particularly favorable.
- the surface shape of the vacuum insulation panels is produced by machining them from polyurethane foam or polystyrene foam or polyisocyanurate foam.
- Fig. 1 In a simplified schematic representation of a table refrigerator with heat insulation side on the inner panel of its door and its housing fixed vacuum insulation panels, in a sectional view from the side and
- FIG. 2 The table refrigerator according to FIG. 1 in a sectional view along the section line II / ll.
- a table refrigerator (10) with a heat-insulating housing (11) is shown in a simplified schematic representation, which has an outer cladding (12), a thermal insulation layer (13) produced by foaming and a non-cutting plastic inner cladding (14), which is based on the adhesive thermal insulation (13) is connected to the outer cladding (12) to form a rigid body.
- the inner cladding (14) has on its side walls (15) non-cutting molded, at approximately equal intervals one above the other support strips (16), which serve as a support for refrigerated goods shelves, not shown.
- vacuum insulation panels (24) for example made of aerogels, glass fibers, or open-cell foams, such as on the inner paneling (14) and on the inside paneling (23) for example, polyurethane foam, polystyrene foam or the like.
- Support bodies made.
- molded bodies (25) made of heat insulation material are used as intermediate layers, the surface (26) of the vacuum insulation panels (24) facing them and the surface of the vacuum insulation panels (24) connected to the entire surface thereof being flat.
- the shaped bodies (25) Opposite the surface (26), the shaped bodies (25) have a surface (27) which is adapted to the surface shape of the door interior trim (23) or the surface shape of the interior trim (14) and which, in the case of the rear wall of the interior trim provided with the evaporator (18) (14) is adapted to the channel pattern of the evaporator (18).
- the surface shaping of the inner linings (14) and (23) or of the evaporator (18) is not only an appropriate support of the supporting strips (16) or the shaping (24) on the door ( 19) is achieved, but at the same time it is ensured that the vacuum insulation panels (24) are essentially fixed over their entire surface at their fastening location by means of the shaped bodies (25) and thus foaming of the heat insulation material (in the housing (11) or the door (19) during the foaming process 13) or (22) with a high thermal insulation quality while avoiding blowholes which reduce the thermal insulation behavior.
