The modular refrigerating appliance also has a cooling circuit, which comprises an evaporator, a condenser, and a compressor, and which is mounted on the first planar heat-insulating element. At least the condenser is, at least in part, mechanically protected on its surface facing away from the first heat-insulating element solely by the construction of the first planar heat-insulating element.

Description

The invention relates to a modular refrigerator, comprising a first planar heat-insulated element and other planar heat-insulated elements, which are connected to each other and again detachable and form a housing of the refrigerator in the connected state, and a, an evaporator, a condenser and a compressor comprising a refrigeration cycle which is arranged on the first planar heat insulated element.

Such a modular refrigeration device is for example from the DE 84 15 798 U1 known. This modular refrigerator consists of two exchangeable side walls, a rear wall, a ceiling wall, a bottom wall and a front door, which are fastened together by means of fastening and articulation means. The side walls, the rear wall, the ceiling wall and the bottom wall are each made as a complete unit, for example, tightened with screws against each other and form the housing of the refrigerator. A compressor, a condenser, a thermostat and a throttle valve of the refrigerator are all attached to the rear wall, wherein the capacitor is mounted on the flat outer surface of the rear wall. The fact that the is attached to the smooth outer surface of the rear wall, this is over and can be damaged relatively easily, especially when transporting the rear wall.

A modular kättegerät according to the preamble of claim 1 is in the US 4,917,256 disclosed.

The object of the present invention is therefore to carry out a modular refrigeration device such that the possibility of damage to the refrigeration circuit and in particular the evaporator and the liquefaction during transport of the rear wall of the modular refrigeration device is reduced, and that the cost of the electrical Energieversogung the entire device is minimized and thus the kättegerät be made as compact as possible.

The object of the invention is achieved by a modular refrigeration device, solved according to claim 1. The modular refrigerating appliance according to the invention is intended in particular to be delivered in disassembled state, ie disassembled, for example to an end consumer, so that this or these the areal thermally insulated elements, for example, two side elements, a bottom element, a ceiling element and a rear wall comprise assemble into a functioning refrigerator. However, areal thermally insulated elements can also be a combination of, for example, a side element and a ceiling element, ie a planar heat-insulated element is a part of the housing of the refrigeration device. Advantageously, the individual sheet-like heat-insulated elements, and in particular the first sheet-like heat-insulating element, comprise an inner lining and an outer lining enclosing a cavity filled with a heat-insulating material. The fact that at least the condenser is mechanically protected solely by the structure of the first thermally insulated element, in particular the risk of damage to the condenser is reduced during the transport of the rear wall. Because the entire refrigeration cycle is arranged on the first heat-insulated element, it can already be filled with the necessary refrigerant, tested and delivered in a functional manner before the delivery of the individual planar heat-insulated elements.

The condenser is particularly well protected if, as is provided according to a preferred embodiment of the modular refrigerating appliance according to the invention, it is integrated in the first planar element. By this embodiment, it is possible to smoothly perform the outer surface of the first planar element, which then preferably represents the rear wall of the housing, whereby a risk of injury during transport of the first planar element is reduced. Since the condenser is integrated within the first planar element, this is also protected from contamination.

According to another variant of the modular refrigerating appliance according to the invention, the liquefier is in heat-conducting contact with the outer lining of the first planar element and / or is foamed onto the heat-insulating material of the first planar element. Thus, conditions for a relatively good heat transfer of the condenser during operation of the refrigerator are given to the ambient air.

According to a further embodiment of the modular refrigeration device according to the invention, the first planar element is provided on the outwardly directed side surface with a recess whose depth is greater than the thickness of the condenser and in which the condenser is arranged. The fact that the recess is made deeper than the thickness of the condenser, it is possible to attach the condenser to the first planar element, which is preferably the rear wall, that the condenser does not protrude from the recess. The border of the indentation thus protects the condenser from mechanical damage. The condenser may be painted on its visible side and an additional plastic protective layer may further protect the condenser from damage. An additional covering, which at least partially covers the indentation, can also provide improved protection of the condenser.

According to a preferred embodiment of the modular refrigerating appliance according to the invention, the indentation is an open channel running along the rear wall.

As a condenser, a so-called wire-needle, roll-bond or tube-on-plate condenser is used according to a variant of the refrigerator according to the invention. Tube-on-plate heat exchangers include e.g. meandering metallic and curved tubes that are connected to a metal plate using different technologies. The attached metal plate can act as a rib and serve for heat transfer to the inner wall of the rear wall. Tube-on-plate heat exchangers are sometimes referred to as hot wall heat exchangers.

According to a variant of the refrigerator according to the invention, the first planar element comprises a niche in which the compressor is mounted. If the first planar element is the rear wall, then this can be made particularly compact if the niche is arranged in the lower region of the rear wall. The size of the niche is preferably adapted to the spatial dimensions of the compressor. So that the compressor can deliver waste heat to the environment of the assembled refrigerator, the niche is accessible from outside the housing according to an embodiment of the refrigerator according to the invention. Since the compressor is mounted in the niche, it does not protrude out of the niche comprehensive rear wall, which the compressor is also protected by the construction of the rear wall from damage.

According to another variant of the modular refrigeration device according to the invention, the indentation opens at its lower end into the niche. This allows air from the niche to flow up the channel, thereby cooling the condenser.

According to a further advantageous embodiment of the modular refrigeration device according to the invention, the condenser, which is then preferably a SpiralVerflüssiger, a tube-finned condenser or a wound Drahtrohrverflüssiger, arranged in the niche.

For an improved cooling of the condenser, a ventilation device associated with the condenser is provided according to a further embodiment of the modular refrigeration device according to the invention. The ventilation device may be arranged at the lower end of the recess and / or in the niche. A ventilation device is e.g. a fan. By the ventilation device, it is possible to make the condenser as small as possible, whereby, for example, reduces the expansion of the indentation.

The evaporator is particularly well protected if, as is provided according to a preferred embodiment of the modular refrigerating appliance according to the invention, it is integrated into the first planar element, which is preferably the rear wall. By this embodiment, it is possible to smoothly perform the inner surface of the first planar element, whereby a risk of injury during transport of the first planar element is reduced. Since the evaporator is integrated within the first planar element, this is also protected from contamination.

The evaporator is according to another variant of the inventive modular refrigeration device in heat-conducting contact with the inner lining of the first planar element and / or is foamed to the heat insulating material of the first planar element. Thus, conditions for a relatively good cooling of the housing interior of the refrigerator are given.

According to a variant of the refrigerator according to the invention, a so-called roll-bond or tube-on-plate condenser is used as the evaporator. If tube-on-plate heat exchangers are used both for the evaporator and for the condenser, these can be the same for the evaporator and condenser, which in turn can reduce the production costs of the refrigerating appliance according to the invention.

Alternatively, in particular a so-called finned evaporator can be used. This is preferably associated with a fan.

In addition to the refrigeration cycle, a refrigerator includes electronic components, such as a regulation for maintaining a target temperature within the refrigeration device.

The refrigeration device according to the invention is provided in particular for the fact that it is assembled by a customer, for example, at home. In addition to a mechanical connection of the planar heat-insulated elements, it is also necessary to produce electrical connections, such as an electrical line from the refrigeration control to the refrigeration cycle. Such an electrical connection can then be made relatively easily if, according to a preferred embodiment of the refrigerator according to the invention, an electrical contact device is integrated in the rear wall which automatically integrates a planar heat-insulated element during the mechanical connection of the rear wall to another of the planar heat-insulated elements electrical counter contact device contacted electrical. Such a contact / mating contact device is for example an electrical plug-socket device. Thus, the refrigeration device according to the invention has as few electrical connection points, both the electrical power supply for the electronic components and electrical control signals from the electronic components to the refrigeration cycle can be passed through the electrical contact / mating contact device.

If, according to a further variant of the refrigeration device according to the invention, all electronic components are combined to form a single electronic unit, the number of electrical lines is reduced. The electronic components include e.g. a temperature sensor, the temperature control electronics, a setting device for setting the target temperature or a lighting device for illuminating the interior of the housing. The electronics unit may e.g. be attached to an inside of one of the planar heat-insulated elements, so that it is accessible only when the door of the refrigerator. Suitably, the electronics unit is attached to the ceiling element or on one of the side elements. In order to reduce the electrical energy consumption of the refrigerator according to the invention, it may be advantageous that the lighting device is switched on when the door of the refrigerator is open and switched off when the door is closed. The lighting device is e.g. with a door opening switch on and off.

For example, To reduce the cost of laying the electrical lines, a channel for performing an electrical line is integrated according to another variant of the refrigerator according to the invention within at least one of the planar heat-insulated elements. This channel may for example have the form of a conduit or be provided for performing a refrigeration cycle connection. Advantageously, the channel is laid in the planar heat-insulated element to which the electronics unit is also attached. It is particularly advantageous if one end of the channel leads to the electronics unit and the other end of the channel leads to the mating contact device, so that e.g. Both the electrical power supply for the electronics unit and the electrical line for the sent from the electronic unit electrical control signals for the refrigeration cycle can be performed in the same channel. This results in a relatively clear and simple electrical cable management. It is also advantageous if the channel runs in the rear wall and ends one end of the channel on the electrical contact device, so that in turn this channel, the electrical power supply for the electronic unit and the electrical line for the sent from the electronic unit electrical control signals for the refrigeration cycle be guided.

According to a further embodiment of the modular refrigerating appliance according to the invention, the latter comprises a holding device for receiving an interior of the refrigerating appliance, which is part of the interior lining. A mounting device is, for example, a ribbed field for receiving storage levels. The holding device is preferably produced during a drawing or injection process of the inner lining enclosing the heat insulation material. By this embodiment, the refrigeration device according to the invention is designed such that functional properties, such as the rib field for Aufnahe the storage level are immanent. As a result, an additional attachment of holding parts for Aufnahe of cultivation or equipment parts is unnecessary.

The FIG. 1 shows a first embodiment of a modular refrigeration unit KG1 according to the invention in the assembled and ready for use state. In the case of the present exemplary embodiment, the refrigeration appliance KG1 comprises two side walls 2 and 3, a ceiling element 4, a bottom element 5, a rear wall 6 and a door 7, which have been assembled to the refrigeration device KG1. The two side walls 2 and 3, the ceiling element 4, the bottom element 5 and the rear wall 6 form in the case of the present embodiment, the housing G1 of the refrigerator KG1, which is closable with the door 7. An interior of the refrigeration device KG1, such as drawers or shelves, are not shown in the figures. But it is a rib field R to Shooting of shelves shown. In the case of the present embodiment, the rib field R was produced during a drawing or injection process of the inner lining of the side walls 2 and 3 enclosing a thermal insulation material.

In order to regulate the temperature of the refrigerating appliance 1, the electronic unit 14 is electrically connected to the compressor 10 in the assembled state of the refrigerating appliance KG1. This electrical connection comprises in the case of the present embodiment, an electrical line 30, which extends in an extending in the ceiling element 4 of the refrigerator KG1 channel, which in the case of the present embodiment is a conduit 31, an electrical line 32, which in a in the Rear wall 6 extending channel, which in the case of the present embodiment, an empty tube 33 extends, and an electrical contact and mating contact device, which is in the case of the present embodiment, an electrical plug-socket device. The socket 34a of the plug-socket device is on the ceiling element 4 and the plug 34b of the plug-socket device is attached to the rear wall 6. The empty tube 33 is in the case of the present embodiment in the insulating foam 12 of the rear wall 6 and the empty tube 31 is foamed in the insulating foam of the ceiling element 4. The one end of the empty tube 31 integrated in the ceiling element 4 leads to the electronics unit 14 and the other end of the empty tube 31 leads to the socket 34a. One end of the empty tube 33 integrated in the rear wall 6 leads to the niche 6c and the other end of the empty tube 33 leads to the plug 34b. The electrical conduit 30 extending in the empty conduit 31 electrically connects the electronics unit 14 to the bushing 34a, the electrical conduit 32 extending in the conduit 33 electrically connects the compressor 10 to the plug 34b, and the plug 34b and the bushing 34a are made such that in the assembled state, they electrically connect the electronic unit 14 to the compressor 10 so that the electronic unit 14 controls the compressor 10 in accordance with the setpoint temperature and the actual temperature measured by the temperature sensor 15.

An intended for the electronic unit 14 electrical power supply in the form of electrical lines 35 and 36 are also laid in the conduits 31 and 33 and are connected via the male connector device miteinender. The necessary for the production of low voltage power supply 37 is fixed in the case of the present embodiment in the niche 6c of the rear wall 6.

Below, the assembly of the refrigeration device KG1 by means of FIGS. 4 to 9 explained in more detail. In order to obtain the housing G1 of the cooling device 1, the bottom element 5 and the rear wall 6 are first connected to furniture fittings 40 in the case of the present exemplary embodiment. The furniture fittings 40 are designed such that the bottom element 5 and the rear wall 6 are again detachable from each other, ie that the housing G1 can also be taken apart again. Some of the furniture fittings 40 are in the FIG. 4 shown in more detail. The FIG. 4 in conjunction with the FIG. 5 also illustrate by way of example how the rear wall 6 and the bottom member 5 by means of some of the furniture fittings 40 are interconnected.

The furniture fittings 40 in the case of the present embodiment each comprise a metal pin 40a provided with a thread 40b. The thread 40b is screwed, for example, with a screwdriver, not shown, in the case of the present embodiment in the back wall 6 pre-drilled holes 41. One of Metal pins 40a 'is in the FIG. 4 still shown in nichtverschraubtem state. The rest, in the FIG. 4 In contrast, metal pins 40a shown are already screwed as screwed into the rear wall 6.

After the metal pins 40a are screwed into the rear wall 6, the bottom element 5, which in the case of the present embodiment comprises predrilled holes 42 corresponding to the metal pins 40a, is brought to the rear wall 6 in the direction of the arrows 43 such that the screws screwed into the rear wall 6 Metal pins 40a are inserted into their corresponding holes 42 of the bottom element 5. Subsequently, the metal pins 40a are provided with locking nuts 40c by means of the screwdriver such that the rear wall 6 and the bottom element 5 are fixedly connected to each other, as shown in FIG FIG. 5 is shown.

After the bottom element 5 and the rear wall 6 are firmly connected to each other by means of the furniture fittings 40, further metal pins 40a are screwed into the rear wall 6 in holes drilled therefor. These bolted metal pins 40a are in the FIG. 6 shown in bolted condition. Thereafter, the ceiling element 4 is brought in the direction of the arrow 50 to the rear wall 6 such that the metal pins 40 a in them corresponding, in the FIG. 6 not shown holes of the ceiling element 4 are inserted. By inserting the metal pins 40a of the rear wall 6 in the holes of the ceiling element 4 are further fastened to the ceiling element 4 socket 34a and attached to the rear wall 6 plug 34b aligned with each other so that they are in the assembly of the ceiling element 4 and the rear wall. 6 automatically connect, so that the electric Kohntakt between the compressor 10 and the electronic unit 14 is made. Finally, the metal pins 40a are still provided with locking nuts 40c such that the rear wall 6 and the ceiling element 4 are firmly connected to each other.

Finally, to completely assemble the housing G1, the two side walls 2 and 3 are also connected to furniture fittings 40 with the rear wall 6, the ceiling element 4 and the bottom element 5. The finished assembled housing G1 is in the FIG. 7 shown.

In addition, two further fittings 70 and 71 are screwed with two screws 72 on the underside of the housing G1. One of the fittings 71 is provided with a pin 73, with which the door 7 of the refrigerator KG1 can be pivotally mounted. Like in the FIG. 8 illustrates, for the attachment of the door 7 to the housing G1, the door 7 is first placed on the pin 73 of the fitting 71. The door 7 comprises a suitable hole 74 for this purpose.

Subsequently, at the top of the housing G1, as in the FIG. 9 can be seen, another fitting 80 screwed by means of screws 81. The fitting 80 includes a pin 82 which is inserted into another hole 83 of the door 7.

The Figures 10 and 11 show a rear wall 106 of a second embodiment of a modular refrigeration device according to the invention. This refrigeration device is up to the rear wall 106 substantially as in the FIGS. 1 to 9 constructed modular refrigeration unit KG1, which is why only the rear wall 106 of the second embodiment will be explained in more detail below. In the case of the present exemplary embodiment, the rear wall 106 likewise comprises an inner lining 106a and an outer lining 106b, respectively, which enclose a cavity filled with a heat-insulating material. The heat insulating material is an insulating foam 1012 in the case of the present embodiment.

At the in the Figures 10 and 11 shown back wall 106 of the second embodiment of a modular refrigeration unit is also the entire refrigeration cycle, essentially comprising an evaporator 108, a condenser 109, a compressor 1010, and the evaporator 108, the condenser 109 and the compressor 1010 connecting, shown only partially in the figures Cables. The evaporator 108, which in the case of the present embodiment is a tube-on-plate heat exchanger, is similar to that in Figs FIGS. 1 to 9 shown refrigeration unit KG1 foamed on the insulating foam 1012 and is in heat-conducting contact with the inner lining 106a.

Like in the FIG. 10 shown, the rear wall 106 comprises an open channel K1 extending on its outside and along the rear wall 106, in which the condenser 109, which in the case of the present embodiment is a Drahtnadelverflüssiger mounted is. The open channel K1 extending along the rear wall 106 is made so deep that the condenser 109 does not protrude beyond the outside of the rear wall 106. This makes it possible to cover the condenser 109 with a lining, not shown in the figures to the outside. The panel extends in the case of the present embodiment to the top of the rear wall 106 and is screwed to the rear wall 106.

Like the rear wall 6 of the refrigerating appliance KG1, in the case of the present exemplary embodiment the rear wall 106 likewise comprises a niche 106c arranged in the lower region of the rear wall 106, in which the compressor 1010 is fastened. The niche 106 c is designed such that it is accessible from outside the housing of the refrigerator according to the second embodiment. The niche 106c extends in the case of the present embodiment over the entire width of the housing. The compressor 1010 is furthermore supplied with electrical energy by means of a mains cable 1013. Further, the open channel K1 extending along the back wall 106 extends to the niche 106c, and the panel covering the channel K1 extends to the top of the niche 106c to completely cover the condenser 109.

In order to better cool the condenser 109, in the case of the present embodiment, in the niche 106c and below the open channel K1 running along the rear wall 106, a fan V1 is fixed, which in the operation of the refrigerator according to the second embodiment, air from below to the condenser 109th blows. Due to the forced cooling of the fan V1, it is possible to make the condenser 109 relatively small, so that the condenser 109 extends in the case of the present embodiment, approximately over one third of the width of the rear wall 106 and thus the width of the open along the rear wall 106 Channel K1 also corresponds in about one third of the width of the rear wall 106.

Similar to the rear wall 6 of the first embodiment of the modular refrigeration unit KG1 runs within the rear wall 106 of the refrigerator according to the second embodiment, a channel in the form of a conduit 1033, in which an electrical line 1032 for driving the compressor 1010 and an electrical line 1036 to supply the electronics unit 14 are laid with electrical energy. In addition, a plug 1034 b is fixed to the rear wall 106, with which the electrical leads 1032 and 1036 are connected. In the assembled state, therefore, the electronics unit 14 is connected to the compressor 1010 electrical. The power supply 1037 necessary for producing the low voltage is fixed in the recess 106c of the rear wall 106 in the case of the present embodiment.

The Figures 12 and 13 show a rear wall 126 of a third embodiment of a modular refrigeration device according to the invention. This refrigeration device is essentially the same as that in FIGS FIGS. 1 to 9 shown modular refrigeration unit KG1 constructed, which is why only the rear wall 126 of the refrigerator according to the third embodiment will be explained in more detail below. In the case of the present embodiment, the rear wall 126 in each case comprises an inner lining 126a and an outer lining 126b which enclose a cavity filled with a heat-insulating material. The heat insulating material is an insulating foam 1212 in the case of the present embodiment.

At the in the Figures 12 and 13 shown back wall 126 of the third embodiment of a refrigerator is also the entire refrigeration cycle. Essentially comprising an evaporator 128, a condenser 129, a compressor 1210 and the evaporator 128, the condenser 129 and the compressor 1210 connecting, only partially shown in the figures lines. The evaporator 128, which in the case of the present embodiment is a tube-on-plate heat exchanger, is like the evaporators 9 and 109 of the two refrigerators according to the first and second embodiments foamed to the insulating foam 1212 and is in heat-conducting contact with the Interior paneling 126a.

Similar to the rear wall 6 of the refrigeration device KG1, in the case of the present embodiment, the rear wall 106 comprises a niche 126c arranged in the lower region of the rear wall 136, in which the compressor 1210 and the condenser 129 are fastened. However, in the case of the present embodiment, the niche 126c extends over the entire width of the housing of the refrigerator according to the third embodiment. The compressor 1210 is further powered by means of a power cable 1213 with electrical energy.

In the case of the present exemplary embodiment, the condenser 129 is a spiral condenser which is forcibly cooled with a fan V2.

Similar to the rear wall 6 of the first embodiment of the modular refrigeration unit KG1 runs within the rear wall 126, a channel in the form of a conduit 1233, in which an electrical line 1232 for driving the compressor 1210 and an electrical line 1236 for supplying the electronic unit 14 with electrical energy are laid. In addition, a plug 1234b is attached to the rear wall 126 to which the electric wires 1232 and 1236 are connected. In the assembled state, therefore, the electronics unit 14 is connected to the compressor 1210 electrical.
