Description

The present invention relates to a deep-drawn hydraulic connection for a domestic appliance.Certain domestic appliances, such as, for example, ventilation appliances, water heaters, heat pumps and / or other air conditioners, which are based on a thermodynamic cycle, can have a functional module and a storage module. The functional module performs this thermodynamic cycle to heat or cool an operating medium. A storage medium is stored in a storage module connected to the functional module. Storage modules can store, for example, hot water or further cooling or heating means.The storage module is hydraulically connected to the functional module in order to enable a discharge of energy. The energy provided by the functional module can thus be stored in the memory module. Likewise, the functional module can cool by removing energy and extract energy from the connected storage medium in the storage module.The storage module can be, for example, a hot water storage device for heating, such as, for example, a floor heating device, or for supplying hot water to an object.The function module and the memory module are often transported and set up separately. It is known that the functional module and the storage module are connected by means of hydraulic connections. For this purpose, hydraulic connections are provided which are readily accessible, so that the storage module can easily be connected to the functional module after the installation. In order for the storage module to be able to be connected to the functional module, the hydraulic connections typically protrude from the functional module in the connection region of the functional module and the storage module can be connected to them, for example plugged on.The hydraulic connections protruding from the connection region of the functional module have the disadvantage that these hydraulic connections can be damaged during transport of the functional module or when the storage module is set up. During the transport and assembly of domestic appliances, it is therefore necessary to take care not to damage these hydraulic connections. For example, the hydraulic connections can be damaged if the storage module is pushed to the functional module for connection.Against this background, it was an object of the invention to provide a hydraulic connection which cannot be damaged during transport and assembly.According to the invention, the object is achieved by the subject matter of the independent claims. Preferred embodiments are defined in the dependent claims.In a first aspect of the invention, a functional module for a domestic appliance is proposed, in particular a domestic appliance for ventilating, heating, preparing hot water and / or cooling, having a housing shell with a connection side and a depression in the connection side of this housing shell, which depression forms an opening of the connection side, wherein a hydraulic connection is arranged in the depression of the connection side, wherein the hydraulic connection is furthermore arranged in such a way that the hydraulic connection is arranged in the interior of the functional module with respect to the opening of the connection side.This ensures that the hydraulic connection does not protrude beyond the surface of the functional module and therefore cannot be damaged during transport, assembly or installation. This simultaneously enables a simple and faster alignment of a storage module, which is connected to the functional module, since it is ensured that no damage can occur to the hydraulic connection during the alignment of the storage module. Thus, it is possible to perform the alignment without having to take care of damage to the hydraulic ports.The opening defined by the depression on the connection side of the functional module preferably corresponds to an opening of a memory module. This makes it possible to easily align the memory module to the functional module. For this purpose, the respective openings are aligned opposite one another.Preferably, more than one hydraulic connection is arranged in the depression of the functional module. According to the invention, all connections for connecting the memory module to the functional module can thus be arranged in the depression. For example, the hydraulic connections can be arranged one above the other with respect to the installation position of the functional module.Preferably, the hydraulic connection or connections can end with the opening of the connection side. This enables the best possible access to the hydraulic connections, wherein at the same time it is ensured that these cannot be damaged during transport or during assembly.Preferably, the hydraulic connection or connections can be pipelines with quick connections. Preferably, quick-acting hydraulic couplings can be used. The quick connectors can be connected to hoses with quick adapters. This makes it possible to easily connect the functional module to a storage module via hoses with suitable quick adapters.A cooling unit of a heat pump is preferably constructed in the functional module. The refrigeration unit contains a heat exchanger, in particular a condenser, in which heat can be exchanged by the refrigerant guided in the refrigeration unit with a heat transfer medium, such as water or brine, for example. Heat is thus provided by the refrigeration unit, which is transferred to the heat transfer medium during heating operation. When transferring heat to the heat transfer medium, the refrigerant is liquefied and the heat transfer medium is heated. The heated heat transfer medium is provided in the pipelines and exactly this heat transfer medium is conducted to the functional module via the hoses to the storage module when the functional module is connected to the storage modules with the quick connections.According to an aspect of the invention, the heat pump in the functional module can preferably be an air-water heat pump which contains an external air seal for fresh air and a connection for outgoing air. If the functional module is also equipped with a ventilation device, the ventilation device is likewise connected to the fresh air and the outgoing air. Thus, exhaust air heat of the ventilation device can also be transferred to an evaporator of the cold unit. Therefore, there is a thermal flow in this case from an exhaust air via the refrigeration unit to the heat transfer medium.According to a further aspect of the invention, the refrigeration unit can be operated in a reverse operation, whereby in particular an evaporator of the refrigeration unit can be defrosted or heat can be extracted from the heat carrier medium in the reverse operation. According to one aspect of the invention, a cooling of the heat carrier medium is brought about in the reverse operation.In a further aspect of the invention, a storage module for a domestic appliance, in particular a domestic appliance for ventilating, heating, supplying hot water and / or cooling, is proposed, having a housing shell of the storage module, which comprises an insulation and a connection side for connecting a functional module and an engagement region for connecting the storage module to a functional module, wherein the engagement region comprises a region which is exposed in the insulation, a first opening of the connection side and a second opening of the housing shell, and wherein a hydraulic connection for connecting the functional module is arranged in the engagement region.The storage module can be easily set up, since no hydraulic connections protrude beyond the surface. Therefore, the hydraulic ports cannot be damaged or cause damage to other components. Due to the arrangement of the hydraulic connections in the engagement region, these are accessible through the second opening. If the storage module is set up such that the first opening in the connection side of the storage module is opposite the opening of the depression of the connection side of the functional module, the hydraulic connections of the functional module are also accessible through the openings and the engagement region of the storage module. It is therefore possible to connect the hydraulic connections of the functional module to the hydraulic connections of the storage module.Preferably, hoses with quick adapters may be used. A person skilled in the art can connect the hoses to the hydraulic connections of the functional module and the storage module through the second opening of the engagement region.Preferably, the storage module, in particular the engagement region of the storage module, can comprise more than one hydraulic connection. It is thus possible for all the hydraulic connections of the storage module that are necessary to connect the storage module to the functional module to be arranged in the engagement region.The hydraulic connections are preferably pipelines with quick connections. Preferably, the hydraulic connections can be connected to hoses with quick adapters. This simplifies the connection of the hydraulic connections of the storage module to the hydraulic connections of the functional module, since the hoses are connected to the pipes through the openings of the engagement region by means of the quick adapters.In a further aspect of the invention, a domestic appliance, in particular a domestic appliance for ventilating, heating, preparing hot water and / or cooling, comprising a functional module and a storage module according to the preceding examples, is proposed. Such a domestic appliance allows both the functional module and the storage module to be set up, installed or aligned without the hydraulic connections being damaged by the fact that they stick to objects or are damaged by another module. If the storage module and the functional module are placed opposite each other with the respective connection sides, so that the openings in the connection sides are situated opposite each other, both the hydraulic connections of the storage module within the engagement region and the hydraulic connections of the functional module can be accessed through the engagement region. This allows the functional module to be connected to the storage module after the storage module has been placed on the functional module and faces it and even though the hydraulic connections are each arranged in the interior of the two modules.Preferably, the hydraulic connection of the functional module is connected to the hydraulic connection of the storage module by means of hoses with quick adapters. For this purpose, a technician can pass through the engagement region in order to connect the hoses to the hydraulic connections. The use of quick adapters or quick couplings allows for easy assembly of the hoses.Preferably, the hydraulic connectors are pipes with quick connectors or quick couplings that fit the quick adapters or quick couplings of the hoses. The use of hoses furthermore allows the path between the hydraulic connections respectively arranged in the respective module to be bridged. Furthermore, a distance between the memory module and the functional module can be compensated.Preferably, in the installed state, the opening of the connection side of the functional module is arranged opposite the first opening of the connection side of the memory module 9. As a result, the hydraulic connections of the functional module can be accessed through the engagement region of the storage module. Thus, the hoses can be mounted between the hydraulic connections of the functional module and the hydraulic connections of the storage module.Further advantageous embodiments and advantages are described below with reference to the attached figures.

FIGS. 2 aand b show schematically and by way of example detailed views of the deep-drawn hydraulic connection. FIG. 3 shows schematically and by way of example a side view of the functional module according to the invention. FIG. 4 shows schematically and by way of example a perspective sectional view of the functional module with connected memory module. FIG. 5 shows schematically and by way of example a side view of the functional module with connected memory module. FIG. 6 shows schematically and by way of example a perspective sectional view of the functional module with connected memory module.FIG. 1 shows a functional module 1 with a so-called deep-drawn hydraulic connection. The functional module 1 can be part of a domestic appliance, such as a heat pump or a refrigerating machine. The functional module comprises three hydraulic connections 6. The tubes may have quick connectors or quick couplings. The functional module comprises a housing shell 2. the housing shell can enclose the functional module from all sides. The housing casing has a connection side. The port 3 side is the side through which the hydraulic ports 6 are connected. In particular, the connection side 3 can be the side to which a memory module is opposite. The connection side has a depression 4. The depression defines an opening 5 of the surface of the connection side 3. The hydraulic connections therefore do not project beyond the surface of the functional module. The depression 4 may have a bottom. The ends of the hydraulic connections 6 can be arranged in the bottom of the depression. In particular, the ends of the hydraulic connections 6 can project into the depression via the base of the depression. The hydraulic connections 6 can be pipes, at the ends of which quick connections are arranged. The ends of the tubes and the quick connectors may be located between the bottom of the recess and the opening of the recess 4.The depression 4 with the ends of the hydraulic connections 6 lying in the depression 4 forms a deep-drawn hydraulic connection. Due to the deep-drawn hydraulic connection, it is not possible to damage the connection region for a storage module, i.e. the region of the functional module 1 to which the hydraulic lines of a storage module are connected, during transport. This is because the connection region is offset inward with respect to the surface of the functional module, so that the surface prevents objects from entering or reaching the connection region.Furthermore, the deep-drawn hydraulic connection can easily and rapidly align the reservoir with the functional module. In particular, since it is not necessary to take care in locations of the modules that protruding hydraulic connections are damaged.FIG. 2 shows a perspective view of the connection side 3 of the functional module 1. the ends of the pipes which form the hydraulic connections 6 and have, for example, quick couplings, project outwards into the depression 4 beyond the base of the depression 4. The ends can end flush with the opening of the depression 4 in the connection side 3 of the functional module 1 or can be at a distance inwards from the opening 5 of the connection side 3 of the functional module.FIG. 2 b shows a sectional view of the functional module in which the inner side of the connection side 3 of the functional module 1 is shown. The figure shows that the depression 4 can protrude from the connection side 3 into the interior space. This means that the depth of the depression 4 can be greater than the wall thickness of the connection side 3. The hydraulic connections 6 are guided through the bottom of the depression 4 from the interior of the functional module to the outside into the depression. The base of the depression 4 can thus be arranged in the interior of the functional module 1 beyond the wall thickness of the connection side 3 or the thickness of the housing casing 2.FIG. 3 shows a side section of the functional module. The depression defines an opening 5 on the connection side 3 of the functional module. The hydraulic connections 6, which may be pipes and may comprise a quick connection or quick coupling, end in front of the surface of the connection side 3 in the recess 4. The hydraulic connections are thus protected from damage.FIG. 4 shows a perspective sectional view of a functional module 1 which is located opposite a memory module 9. The openings 5, 13 of the connection sides 3, 11 of the functional module and of the memory module are arranged opposite one another. The hydraulic connections 6 of the functional module 1 are arranged behind the opening 5 of the connection side 3, which is formed by the depression 4.The storage module 9 comprises a housing shell 10 and the memory of the storage module is surrounded by insulation. In the insulation of the storage module, there is a exposed region which forms the engagement region 12. The engagement region further comprises the first opening 13 of the connection side 11 of the memory module 9 and a second opening 14 of the housing shell of the memory module. The hydraulic connections 15 of the storage module are arranged in the exposed engagement region 12. The hydraulic connections 15 of the storage module 9 are connected via hoses 7 to the hydraulic connections 6 of the functional module. The hoses may have quick adapters or quick couplings that cooperate with the corresponding connections or couplings of the hydraulic connections 6 15. The exposed engagement region 12 allows the pipelines 15 of the storage module to be connected to the functional module 1 by means of hoses 7 with quick adapters.As shown in FIG. 4, the functional module can be set up and the memory module can then be slid onto the functional module. Subsequently, the hoses 7 can be connected to the hydraulic connections 6, 15 of the functional module and the storage module through the engagement region.FIG. 5 is an exemplary plan view of the functional module and a memory module arranged opposite thereto. The hydraulic connections 6 of the functional module 1 in the form of pipes with couplings are guided through the bottom of the depression 4 into the depression. Opposite the opening 5 of the connection side 3 of the functional module defined by the depression, the opening 13 of the connection side 11 of the memory module 9 is arranged. Due to the openings 5, 13 being situated opposite one another, the hydraulic connections of the functional module 1 can be accessed through the engagement region. Thus, an engineer can introduce hoses 7 through the second opening of the engagement region into the engagement region and connect one end of a hose in each case to a hydraulic connection of the functional module and another end to a hydraulic connection 15 of the storage module 9. For this purpose, quick-action couplings 8 can be provided on the pipes which form the hydraulic connections 6, 15 and the hoses 7. The hydraulic connections 15 of the storage module can be arranged offset with respect to the hydraulic connections 6 of the functional module 1. The offset is compensated for by the hoses. The engagement region can be configured such that the opening 13 of the connection side 11 of the storage module 9 is arranged offset with respect to the hydraulic connections of the storage module 9. This makes it possible to ensure that the openings 5, 13 of the connection sides 3, 11 of the storage module 9 and of the functional module 1 are opposite one another, even if the hydraulic connections 6, 15 are not opposite one another. The engagement region 12 is designed such that there is sufficient space to connect the hoses 7 through the openings 5, 13 of the connection sides 3, 11 to the hydraulic connections 6 of the functional module. Furthermore, the engagement region 12 is designed such that there is sufficient space to connect the hoses 7 to the hydraulic connections 15 of the storage module 9.FIG. 6 shows a perspective section through a functional module and through a memory module arranged opposite. The tubes 6 are guided into the depression through the bottom of the depression 4. In the depression, a connection is arranged via which the tubes are connected to the hoses. The hoses are connected at their other end to the hydraulic connections 15 of the storage module.List of reference characters1 Functional module 2 Housing shell of the functional module 3 Connection side of the functional module 4 Depression 5 Opening of the connection side of the functional module 6 Hydraulic connection of the functional module 7 Hose 8 Quick adapter / quick coupling 9 Storage module 10 Housing shell of the storage module 11 Connection side 12 Engagement region 13 First opening of the connection side of the storage module 14 Second opening of the engagement region for connecting the hydraulic connections 15 Hydraulic connections of the storage module
