Description

TECHNICAL FIELD

[0001] The present invention relates to a refrigerant line arrangement for a refrigeration appliance and a refrigeration appliance, in particular a household refrigeration appliance such as a fridge-freezer combination. STATE OF THE ART

[0002] Refrigeration appliances, particularly household refrigeration appliances with more than one refrigeration compartment, for example, fridge-freezer combinations with a refrigeration compartment and a freezer compartment, often have a refrigeration compartment evaporator for cooling the refrigeration compartment and a freezer compartment evaporator for cooling the freezer compartment. Some configurations include an outlet of the refrigeration compartment evaporator and an inlet of the freezer compartment evaporator connected by a connecting pipe, with an outlet of the freezer compartment evaporator connected by a suction pipe to a suction-side inlet of a compressor. A refrigerant can be supplied to the evaporators by means of the compressor via one or more supply lines.

[0003] Typically, the evaporators and a refrigerant line assembly, which includes the suction pipe, the connecting pipe, and the supply lines, are mounted separately. For example, the refrigerant line assembly can be mounted as a pre-assembled unit on the freezer and refrigerator compartments. Quick and easy installation without damaging the refrigerant line assembly is desirable.

[0004] DE 10 2016 208 494 A1, US 2 329 139 A, US 2 434 118 A, GB 2 418 478 A, WO 2017 / 198641 A1, WO 2017 / 025270 A1 and DE 10 2018 202008 A1 disclose refrigeration devices with connected lines. SUMMARY OF THE INVENTION

[0005] It is one of the objects of the present invention to provide improved solutions for refrigerant line arrangements of refrigeration devices.

[0006] This object is achieved according to the invention by a refrigerant line arrangement having the features of claim 1 and by a refrigeration device having the features of claim 11.

[0007] According to a first aspect of the invention, a refrigerant line arrangement for a refrigeration device is provided. The refrigerant line arrangement comprises a suction pipe with a first end region provided for connection to an outlet of a first evaporator, which has a curved first pipe connection section, and a second end region provided for connection to an inlet of a compressor, and a connecting pipe with a first end region provided for connection to an outlet of a second evaporator and a second end region provided for connection to an inlet of the first evaporator, which second end region has a curved second pipe connection section, wherein the first pipe connection section and the similarly curved second pipe connection section each run parallel to one another and are fastened to one another.

[0008] According to a second aspect of the invention, a refrigeration appliance, in particular a household refrigeration appliance, is provided. The refrigeration appliance comprises a first container which defines a first refrigeration compartment for receiving refrigerated goods, e.g. frozen goods, a first evaporator which is thermally coupled to the first refrigeration compartment, a second container which defines a second refrigeration compartment for receiving refrigerated goods, a second evaporator which is thermally coupled to the second refrigeration compartment, a compressor for compressing refrigerant and a refrigerant line arrangement according to the first aspect of the invention. The first end region of the suction pipe is connected to an outlet of the first evaporator and the second end region of the suction pipe is connected to an inlet of the compressor. Furthermore, the first end region of the connecting pipe is connected to an outlet of a second evaporator and the second end region of the connecting pipe is connected to an inlet of the first evaporator.Furthermore, the refrigeration device has a condenser which is connected to an outlet of the compressor and at least to an inlet of the second evaporator.

[0009] One idea underlying the invention is to connect the connecting pipe and the intake manifold to one another in respective pipe connection sections. The pipe connection sections of the intake manifold and the connecting pipe are curved or bent sections. Thus, a curved region of the intake manifold and a similarly curved region of the connecting pipe extend one above the other or overlap, and the connecting pipe and intake manifold are fastened to one another in this overlapping region. This allows for a simple fixation of the intake manifold and the connecting pipe with respect to at least two degrees of freedom.

[0010] By attaching the intake manifold and connecting pipe to each other in their respective pipe connection sections, a reliably defined arrangement of the end sections of the intake manifold and connecting pipe relative to each other is achieved. This advantageously reduces the effort required to position the individual end sections of the connecting pipe and intake manifold relative to the evaporator connections, thus facilitating assembly.

[0011] Advantageous embodiments and further developments arise from the subclaims which refer back to the independent claims in conjunction with the description.

[0012] The first evaporator can, for example, be a freezer compartment evaporator for cooling a freezer compartment. The second evaporator can, for example, be a refrigerator compartment evaporator for cooling a refrigerator compartment. However, it is generally possible for the first evaporator to be provided for cooling or dissipating heat from a first refrigeration compartment and the second evaporator to be provided for cooling or dissipating heat from a second refrigeration compartment, wherein the second refrigeration compartment is preferably cooled to a temperature that is higher than a temperature in the first refrigeration compartment.

[0013] According to some embodiments, it can be provided that the refrigerant line arrangement has a first supply line for connecting a condenser, which is connected to an outlet of the compressor, to an inlet of the second evaporator. Optionally, the first supply line can be designed as a capillary which extends at least partially in contact with the suction pipe. Thus, at least part of the refrigerant line arrangement can fulfill the function of an intake manifold throttle heat exchanger, whereby high energy efficiency is achieved with a compact design. Further optionally, it can be provided that the first supply line is also fastened to the connecting pipe. For example, the first supply line can be arranged at least partially in contact with the connecting pipe.By fixing the suction pipe and the connecting pipe to each other in their pipe connection sections, kinking of the first supply line attached to the suction pipe and the connecting pipe can be reliably avoided in these cases.

[0014] According to some embodiments, the refrigerant line arrangement can have a second supply line for connecting the outlet of the compressor to the inlet of the first evaporator, one end of the second supply line opening into the connecting pipe. For example, the connecting pipe can have a branch piece between its first and second end region, in particular between the second pipe connection section and the first end region, to which branch piece the second connecting pipe is connected. Generally, the second supply line is fluidly connected to the connecting pipe in a region lying outside the first refrigeration compartment and outside the second refrigeration compartment, or the branch piece lies outside the first and second refrigeration compartment. This allows the optional second supply line to be installed and connected very easily.

[0015] According to some embodiments, the second supply line may be configured as a capillary tube, which extends at least partially into contact with the intake manifold. Thus, at least part of the refrigerant line arrangement can fulfill the function of an intake manifold throttle heat exchanger, thereby achieving high energy efficiency with a compact design.

[0016] According to some embodiments, the pipe connecting sections may be configured as elbows. For example, each pipe connecting section may comprise two parallel pipe sections that are connected to each other by an arcuate pipe section.

[0017] According to some embodiments, the pipe connecting sections may be configured as arcs. For example, each pipe connecting section may have a circularly curved section as an arc that connects two straight pipe sections extending transversely to each other.

[0018] According to some embodiments, the pipe connection sections may be configured as a loop. For example, the respective pipe connection section may extend spirally with at least one winding or over at least 360 degrees.

[0019] According to some embodiments, the pipe connecting sections may each have at least one elbow and / or at least one bend. For example, stepped configurations may be provided. It is also conceivable for one elbow or one bend to extend in a first plane and another elbow or another bend to extend in a second plane.

[0020] According to some embodiments, the pipe connection sections can be secured to one another by means of one or more fixing devices, each of which encloses the first and second pipe connection sections. Such a connection, which encloses or clamps the pipe connection sections together, offers the advantage of being easy and inexpensive to install. At the same time, a reliable fixing of the pipe connection sections to one another can be achieved. Optionally, cable ties, clamps, or adhesive tape sections can be provided as fixing devices.

[0021] According to some embodiments of the refrigeration device, it can be provided that the refrigerant line arrangement, as described above, has a first supply line, which can be designed, for example, as a capillary that extends at least partially in contact with the suction pipe. In this case, the outlet of the condenser is connected to the inlet of the second evaporator by means of the first supply line. This can comprise both a direct connection and a variant in which additional hydraulic elements are arranged between an inlet of the supply line and the outlet of the condenser, such as a line section, a dryer, one or more valves, or the like.

[0022] According to some embodiments of the refrigeration device, the second evaporator can be implemented as a finned evaporator and arranged within the second refrigeration compartment, wherein the second container has a recess through which the first end region of the connecting pipe and the first supply line are passed. The finned evaporator can, for example, have a plurality of fins which are connected to a refrigerant line. In addition, a fan can be provided which is designed to convey air over the cooling fins. For example, the finned evaporator can be arranged behind a cover in the second refrigeration compartment. The passage of the first supply line and the connecting pipe through a common recess further facilitates the assembly of the refrigeration device.

[0023] According to some embodiments of the refrigeration device, it can be provided that the refrigerant line arrangement, as described above, has a second supply line which opens into the connecting pipe. As already mentioned, the second supply line can be designed as a capillary which extends at least partially in contact with the suction pipe. In this case, the inlet of the first evaporator is connected to the outlet of the condenser by means of the second supply line. Similar to the optional first supply line, a direct connection can be provided or additional hydraulic elements can be arranged between an inlet of the supply line and the outlet of the condenser, such as a line section, a dryer, one or more valves or the like.For example, a solenoid valve may be provided, to which a line coming from the condenser is connected on the inlet side and the first and second supply lines are connected on the outlet side. The solenoid valve may be configured to vary the amount of refrigerant supplied to the first or second supply line.

[0024] According to some embodiments, the first evaporator can be implemented as a finned evaporator and arranged within the first refrigeration compartment, wherein the first container has a first recess through which the second end region of the connecting tube passes, and a second recess through which the first end region of the suction tube passes. Since the connecting tube and the suction tube are fastened to one another in their pipe connection sections, a stationary arrangement of the first end region of the suction tube relative to the first end region of the connecting tube can be reliably achieved, which advantageously facilitates insertion into the first and second recesses. The finned evaporator can be implemented as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Fig. 1 shows, by way of example and in a schematic manner, a hydraulic circuit diagram of a refrigeration device 100, which can in particular be a household refrigeration device. As in Fig. 1 As shown, the refrigeration device 100 has a first container 130, a first evaporator 140, a second container 110, a second evaporator 120, a compressor 150, and a condenser 160. Furthermore, the refrigeration device 100 comprises a coolant line arrangement 1 for hydraulically connecting the compressor 150 or the condenser 160 to the second evaporator 120 and the first evaporator 140, as well as the evaporators 120, 140 to one another. Additionally, the refrigeration device 100 can have an optional dryer 170 and a likewise optional valve arrangement 180.

[0028] Fig. 2 shows a schematic view of the structure of the refrigeration device 100, wherein for reasons of clarity only the second container 110, the first container 130 and the refrigerant line arrangement 1 are shown.

[0029] The second container 110 can, for example, be designed essentially cuboidally, as shown in Fig. 2 shown by way of example, and defines an interior space which forms a second refrigeration compartment 111 for receiving refrigerated goods, such as food, drinks, etc. The second container 110 may have a recess or through-opening 113 for the passage of one or more pipes. As shown in Fig. 2 As shown by way of example, the recess 113 can be formed, for example, on a rear wall 115 of the second container 110.

[0030] The first container 130 may, for example, be substantially cuboid-shaped with an optional step, as shown in Fig. 2 shown by way of example. In general, the first container 130 defines an interior space which forms a first refrigeration compartment 131 for receiving refrigerated goods, such as food, beverages, etc. The first container 130 can have a first recess or through-opening 133 and a second through-opening 134. The through-openings 133, 134 serve for the passage of pipes and can, for example, be arranged one above the other with respect to a vertical direction V, as shown in Fig. 2 As shown in Fig. 2 As further shown by way of example, the recesses or through openings 133, 134 can be formed, for example, on a rear wall 135 of the first container 130.

[0031] As in Fig. 2 As shown by way of example, the second container 110 can be arranged above the first container 130 with respect to the vertical direction V. Preferably, the second container 110 and the first container 130 are surrounded by insulation (not shown).

[0032] With reference to Fig. 1 The hydraulic circuit of the refrigeration device 100 is explained below. Fig. 1 The refrigerant line arrangement 1 is shown only symbolically to indicate the hydraulic connections. Exemplary designs of the refrigerant line arrangement 1 are shown in the Fign. 2 bis 6 shown and are explained in detail below.

[0033] As in Fig. 1 As shown by way of example, the refrigerant line arrangement 1 comprises a suction pipe 2, a connecting pipe 3, an optional first supply line 4 and a likewise optional second supply line 5.

[0034] As in Fig. 1 As shown, the second evaporator 120 is thermally coupled to the second refrigeration compartment 111 in order to extract heat from the second refrigeration compartment 111. For example, the second refrigeration compartment 111 can be a refrigeration compartment, and the second evaporator 120 can be configured to cool the refrigeration compartment 111 to a temperature between 0.5°C and 15°C. In the following, purely by way of example and without limiting the generality of the invention, reference is made to a refrigeration compartment evaporator 120 as the first evaporator and a refrigeration compartment 131 as the first refrigeration compartment. Likewise, the second container 110 is also referred to below as the refrigeration compartment container 110, without limiting the generality of the invention.

[0035] The cooling compartment evaporator 120 can, for example, be arranged within the cooling compartment 111 or in the interior space defined by the cooling compartment container or the second container 110. Optionally, the cooling compartment evaporator 120 can be implemented as a finned evaporator. As shown in Fig. 1 symbolically shown, a fan 123 can be assigned to the cooling compartment evaporator 120, which is implemented as a finned evaporator, with which air can be circulated within the cooling compartment 111 and guided over cooling fins of the cooling compartment evaporator 120.

[0036] The first evaporator 140 is thermally coupled to the first refrigeration compartment 131 in order to extract heat therefrom. For example, the first refrigeration compartment 131 can be a freezer compartment and the first evaporator 140 can be configured to cool the freezer compartment 131 to a temperature of less than 0°C. However, the first refrigeration compartment 131 can also be a refrigeration compartment which is cooled by the first evaporator 140 to a temperature of greater than 0°C, e.g., in a range between 0.5°C and 15°C. In the following, purely by way of example and without limiting the generality of the invention, reference is made to a freezer compartment evaporator 140 as the first evaporator and a freezer compartment 131 as the first refrigeration compartment. Likewise, the first container 130 is also referred to below as the freezer compartment container 130, without limiting the generality of the invention.

[0037] The freezer compartment evaporator 140 can, for example, be arranged within the freezer compartment 131 or in the interior space defined by the freezer compartment container 130. Optionally, the freezer compartment evaporator 140 can be implemented as a finned evaporator. As shown in Fig. 1 symbolically shown, a fan 133 can be assigned to the freezer compartment evaporator 140, which is implemented as a finned evaporator, with which air can be circulated within the freezer compartment 131 and guided over cooling fins of the freezer compartment evaporator 140.

[0038] As in Fig. 1 As shown schematically, an outlet 122 of the refrigerator compartment evaporator 120 is connected by the connecting pipe 3 of the coolant line arrangement 1 to an inlet 141 of the freezer compartment evaporator 140, so that refrigerant can be introduced from the refrigerator compartment evaporator 120 into the freezer compartment evaporator 140.

[0039] The compressor 150 is designed to compress refrigerant, in particular gaseous refrigerant. An inlet 151 of the compressor 150 is connected via the suction pipe 2 of the coolant line arrangement 1 to an outlet 142 of the freezer compartment evaporator 140, as shown in Fig. 1 is shown schematically. An output of the compressor 152 is connected to an inlet 161 of the condenser 160. The compressor 150 thus draws refrigerant from the freezer compartment evaporator 140, compresses the refrigerant, and feeds it to the condenser 160, in which heat from the refrigerant is dissipated to the environment.

[0040] As in Fig. 1 As shown by way of example, an outlet 162 of the condenser 160 can optionally be connected to a dryer 170, which is designed to separate gaseous and liquid components of the refrigerant. The optional valve arrangement 180, which, as shown in Fig. 1 shown, may be arranged downstream of the optional dryer 170, may have a shut-off valve 181 for interrupting the coolant circulation. Alternatively or additionally, the valve arrangement 180 may have a control valve 182 to which the optional first supply line 4 and the optional second supply line 5 are connected. The control valve 182 may, for example, be designed as a solenoid valve and be configured to feed coolant selectively into the first supply line 4 or the second supply line 5 or generally to vary a distribution of the mass flow of coolant between the first and second supply lines 4, 5.

[0041] Generally, the outlet 162 of the condenser 160 is connected to an inlet 121 of the refrigeration compartment evaporator 120, e.g. as in Fig. 1 shown via the optional first supply line 4, and connected to the inlet 141 of the freezer compartment evaporator 140, e.g. via the optional second supply line 5, as in Fig. 1 shown as an example. With the help of the compressor 150, coolant can be circulated through the condenser 160 and the evaporators 120, 140. The Fig. 1 The connection of compressor 150, condenser 160, refrigerator compartment evaporator 120 and freezer compartment evaporator 140 shown as an example is also called a "double-serial circuit".

[0042] In the Fign. 2 bis 6 Structural designs of the refrigerant line arrangement 1 are shown as examples. As shown in Fig. 1 As can be seen, the suction pipe 2 is fluidically connected at a first end to the outlet 142 of the freezer compartment evaporator 140 and at a second end to the inlet 151 of the compressor 150. A first end region 21 of the suction pipe 2 adjoining the first end is guided through the second recess 134 of the freezer compartment container 130, as shown in Fig. 2 As shown in Fig. 2 As further shown by way of example, the first end section 21 of the suction pipe 2 has a first pipe connection section 25 in an area located outside the freezer compartment 131. Fig. 3 shows the Fig. 2 Coolant line arrangement 1 shown in an enlarged view. As shown in the Fign. 2 and 3As shown, the first pipe connection section 25 can be designed, for example, as a knee, which has a straight first pipe section 25A, a second pipe section 25B running parallel thereto, and an arcuate pipe section 25C connecting the first and second pipe sections 25A, 25B. As will be explained below, other designs of the first pipe connection section 25 are also conceivable. In general, the first pipe connection section 25 has a curved profile or at least one curved section, e.g., the third pipe section 25C, as shown in the Fign. 2 and 3 shown as an example.

[0043] The connecting pipe 3 is connected with a first end to the outlet 122 of the refrigerator compartment evaporator 120 and with a second end to the inlet 141 of the freezer compartment evaporator 140. As in Fig. 2 As shown by way of example, a first end region 31 of the connecting tube 3 adjoining the first end is passed through the recess 113 of the refrigeration compartment container 110 and a second end region of the connecting tube 3 adjoining the second end is passed through the first recess 133 of the freezer compartment container 130. As shown in the Fign. 2 and 3 As shown by way of example, the connecting pipe 3 has a second pipe connection section 35 in its second end region 32, in a region located outside the freezer compartment 131. In the Fign. 2 and 3It is shown by way of example that the second pipe connection section 35 is designed as an elbow, which has a straight first pipe section 35A, a second pipe section 35B running parallel to this, and an arcuate pipe section 35C connecting the first and second pipe sections 35A, 35B. The second pipe connection section 35 is generally shaped identically to the first pipe connection section 25 and thus has a curved course or at least one curved section.

[0044] As in the Fign. 2 and 3As shown, the first pipe connection section 25 and the second pipe connection section 35 are arranged parallel to one another and fastened to one another. This means that in their pipe connection sections 25, 35, the suction pipe 2 and the connecting pipe 3 run parallel to one another or overlap one another and are fastened to one another, e.g., by means of one or more fixing devices 6, which each enclose the first and second pipe connection sections 25, 35. The fixing devices 6 can be, for example, cable ties, clamps, or adhesive tape sections.

[0045] By attaching the suction pipe 2 and the connecting pipe 3 to each other in the pipe connecting sections 25, 35, which have at least one curved section, the suction pipe 2 and the connecting pipe 3 are stably fixed relative to each other. This allows at least the suction pipe 2 and the connecting pipe 3 to be easily mounted as a prefabricated assembly on the refrigerator compartment container 110 and the freezer compartment container 130.

[0046] As in Fig. 2 As shown schematically, the first supply line 4 can be designed, for example, as a capillary which extends at least partially in contact with the suction pipe 2. As shown in Fig. 2 As shown by way of example, a first section of the first supply line 4 can be in contact with the suction pipe 2 between the first and second end regions 21, 22 thereof, and a second section of the first supply line 4 can be in contact with the connecting pipe 3 between the first and second end regions 31, 32 thereof. Optionally, the first supply line 4 can be guided together with the connecting pipe 3 through the recess 113 of the cooling compartment container 110.

[0047] The second supply line 5 can optionally also be designed as a capillary, which extends at least partially in contact with the suction pipe 2. As in Fig. 2 As shown by way of example, the second supply line 5 can extend, for example, over the entire length of the suction pipe 2 between its first and second end regions 21, 22 in contact therewith. As shown in Fig. 2 As further shown by way of example, one end of the second supply line 5 can be inserted into the connecting pipe 3. For example, the connecting pipe 3 can have a lateral branch section 34 to which the end of the second supply line 5 is connected, as shown in Fig. 2 is shown by way of example. Since the suction pipe 2 and the connecting pipe 3 are stably fastened to one another in their pipe connection sections 25, 35, kinking or other damage to the second supply line 5 during handling and transport of the refrigerant line arrangement 1 can be prevented.

[0048] As already explained and in the Fign. 2 and 3 As shown by way of example, the pipe connection sections 25, 35 can be implemented, for example, as elbows. However, the pipe connection sections 25, 35 are not limited to this. Fig. 4 For example, shows a refrigerant line arrangement 1 in which the pipe connection sections 25, 35 each have at least one elbow K and a bend B. As in Fig. 4 As shown by way of example, it can be provided that knee K and arch B each extend in different planes.

[0049] In Fig. 5 a refrigerant line arrangement 1 is shown by way of example, in which the pipe connection sections 25, 35 are designed as a loop. As in Fig. 1 As shown schematically, the suction pipe 2 and the connecting pipe 3 can be bent in their pipe connection sections 25, 35 in a circular manner, similar to a spiral spring, to form a spiral with at least one winding.

[0050] In general, the pipe connection sections 25, 35 are thus curved or have at least one curved section. In the simplest case, the pipe connection sections 25, 35 can thus be formed, for example, as an arc.

[0051] Although the present invention has been explained above using exemplary embodiments, it is not limited thereto, but can be modified in a variety of ways. In particular, combinations of the above embodiments are also conceivable. REFERENCE SYMBOL
