Definitions

• the present invention relates to a refrigerator, which is particularly intended for installation in a furniture niche. Two different designs are currently widespread for such refrigeration devices.
• an essentially cuboidal heat-insulating housing has a machine room in which at least one compressor for the refrigerant circulating in the refrigeration device is accommodated.
• a condenser for the refrigerant is freely suspended on the rear wall of the insulating housing and cooled by the convection of rising air that heats up on the condenser.
• the object of the present invention is to provide a refrigeration device and assemblies for a refrigeration device which achieve high energy efficiency and at the same time allow space to be used very economically in an installation recess.
• Another object is to provide a method for installing such a refrigerator in a piece of furniture.
• a refrigeration device with the features of claim 1, assemblies with the features of claims 9 and 10 and a method according to claim 11.
• the refrigeration device according to the invention By removing the conventional fixed connection between the heat-insulating housing on the one hand and the base assembly on the other hand, in the refrigeration device according to the invention, the possibility is created of locating the two separately in largely arbitrary positions with respect to one another in a piece of furniture such as a kitchen cupboard.
• An easily accessible zone of the piece of furniture can be selected for accommodating the first structural unit comprising the housing, while the second structural unit comprising the compressor can be placed in a poorly accessible zone, the other use of which is not very attractive or which would otherwise not be usable at all.
• Such a zone is in particular the plinth area in most kitchen furniture, in the immediate vicinity of the floor.
• the refrigeration device according to the invention thus opens up a previously unused space as a so-called machine room, which results in a storage space gain either for the refrigeration device or for the built-in cabinet which accommodates the refrigeration device.
• a coupling is preferably provided in a refrigerant line connecting the two assemblies, which enables the two assemblies to be assembled separately from one another in the furniture and to be assembled only after assembly ,
• Such a coupling preferably consists of two parts, which are each attached to the line section of the first assembly or the second assembly, and which are self-locking in the uncoupled state.
• Such clutches which are designed to prevent the escape of refrigerant in the uncoupled state, are known from air conditioning technology. Their use makes it possible to fill two parts of the refrigerant circuit of the refrigeration device according to the invention, which are allotted to the first and the second assembly, independently of one another in the factory with refrigerant and yet to prevent an uncontrolled escape of refrigerant into the atmosphere.
• the second assembly is expediently equipped with a forced ventilation so that it can also be installed in zones of a piece of furniture that would otherwise be insufficiently coolable.
• a condenser can optionally be provided as part of the first or the second assembly.
• the second assembly is forced-ventilated, it makes sense to integrate the condenser in the second assembly.
• a condensate line for draining moisture which is deposited in the interior of the housing is expediently routed together with the refrigerant line.
• the condensate line like the refrigerant line, is expediently provided with a coupling.
• An evaporator shell, at which the condensation water line ends, is expediently integrated in the second assembly in order to use the waste heat released there by the compressor to evaporate the condensation water.
• Fig. 1 shows a schematic section through an inventive refrigerator, installed in a kitchen cabinet.
• the built-in cabinet 1 shown in section in FIG. 1 has in its upper area a niche 2 which receives a first assembly 3 of the refrigeration device according to the invention.
• This first assembly 3 essentially comprises a heat-insulating housing with a body 4 and a door 5, which have an interior space 6 for storing refrigerated goods enclose.
• the interior 6 is shown by way of example without subdivision and with a single evaporator 7 on its rear wall, of course it could also be divided into several different temperature zones by partitions, which can optionally be equipped with their own evaporator, which is independent of the evaporators the other zones can be supplied with refrigerant, or it could be a device in no-frost design, in which the evaporator is housed in a chamber communicating from the interior via forced ventilation.
• An inlet line 8 and an outlet line 9 for the refrigerant supply to the evaporator 7 are led out at the rear of the body 4 and end together on a coupling part 10.
• the coupling part 10 thus has three connector elements, one for each line 8, 9, 12 , wherein at least the connector elements associated with the lines 8, 9 are self-closing when the coupling part 10 is not connected, in order to prevent refrigerant from escaping from the evaporator 7 and the lines 8, 9 into the open.
• the recess 13 is not cooled. Its depth is slightly less than that of the niche 2, so that between a rear wall 15 of the niche 13 and a wall 16 on which the built-in cupboard 1 is set up, a shaft 17 remains free, the niche 2 with a base cavity 18 of the cupboard 1 combines.
• a second assembly 19 of the refrigeration device rests in the base cavity 18, e.g. immediately above the floor.
• This second assembly 19 comprises a compressor
• the two coupling parts 10, 23 connect the outlet line 9 to the suction line 21, the inlet line 8 to the pressure line 22 and the outlet line 12 to an outlet line 26 which opens onto an evaporation tray 27 mounted on the compressor 20.
• the lines 21, 22 associated with the refrigerant are self-closing in the non-connected state.
• the refrigeration device according to the invention is supplied by the manufacturer in the form of the two assemblies 3 and 19 which are not connected to one another.
• the assembly is carried out by placing the first assembly 3 in the niche 2 as usual from a conventional refrigerator and inserting the assembly 19 into the socket cavity 18, e.g. from the front after a front bezel 28 of the socket cavity has been temporarily removed.
• the two coupling parts 10, 23 are joined together, for example by - assuming a sufficient length of the lines 8, 9, 12 - after the first assembly 3 has been placed and the lines 8, 9, 12 and the coupling part 10 have been passed through through the shaft 17, the coupling part 10 is pulled out through the base cavity 17 and joined to the coupling part 23 before the second assembly 19 is pushed into place.
• the separation of the two modules 3 and 19 according to the invention makes it possible to simultaneously mount the housing at a height which is easily accessible to a user and to use the conventionally unused base cavity of the built-in cabinet 1 for accommodating the second module 19.
• This frees up a volume of approx. 20 liters in comparison with the conventional designs of refrigeration appliances in the niche 2 described at the beginning.
• the installation niche can be reduced in height with the same volume of the interior 6 corresponding to these 20 liters, which creates additional space in the built-in cabinet 1 for other purposes, or the interior 6 of the refrigerator can be enlarged accordingly if the dimensions of the niche 2 remain unchanged ,
