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 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.
- 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 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 ,
