Description

[0001] The present invention relates to a domestic appliance such as a heat pump, a hot water tank, or an instantaneous water heater. Such a domestic appliance typically has several hydraulic connections, each of which requires the connection of corresponding pipes.

[0002] EP 3 462 104 B1 discloses a domestic appliance with a storage tank and a hydraulic unit on the storage tank. The hydraulic unit has several connections that protrude above the top of the hydraulic module. Some of these hydraulic connections are each at the same distance from the rear, meaning that these connections are connected in a straight line.

[0003] It is an object of the present invention to provide a domestic appliance with an improved hydraulic connection option.

[0004] This object is achieved by a domestic technology device according to claim 1.

[0005] Thus, a domestic appliance is provided with a housing having a front, a rear, a top, and a first and second side surface. A plurality of first hydraulic connections are provided on one of these sides, each of the first hydraulic connections being at a different distance from the rear and the first side surface.

[0006] This means that the hydraulic connections are not arranged parallel to one of the sides of the housing.

[0007] According to one aspect of the present invention, the first plurality of hydraulic ports are arranged diagonally on one of the sides.

[0008] By varying the distances of the respective first hydraulic connections to both the rear and the first side, a hydraulic connection arrangement can be achieved that allows for flexible connection of the hydraulic connections. The hydraulic pipes connected to the respective first hydraulic connections can then run upwards, to the left, or to the right, i.e., to the first or second side surface.

[0009] Alternatively, the hydraulic pipes connected to the hydraulic connections can run forward.

[0010] Alternatively, the hydraulic pipes connected to the first hydraulic ports can run upwards, forwards, left, or right. The hydraulic pipes do not have to run in the same direction. This allows for a very flexible arrangement of the hydraulic ports and the hydraulic pipes connected to them.

[0011] Because the first hydraulic connections have a different distance to the first or second side surface as well as a different distance to the rear, the hydraulic connections are offset in such a way that a variety of connection options are available.

[0012] According to one aspect of the present invention, a frame with a plurality of recesses is provided on one side of the hydraulic housing, in particular on the side where the hydraulic connections are located. The frame can also be part of the housing. The recesses or openings are designed such that the hydraulic pipes coupled to the respective first hydraulic connections can run through them. This makes it possible for this frame to represent the end or closure of the housing of the domestic appliance. This makes it possible to connect the hydraulic pipes laterally through the recesses, even if this connection is against a wall.

[0013] The frame can have a plurality of openings for the hydraulic pipes. The housing can, in particular, represent a housing for a hydraulic module that is coupled to a heat pump or a hot water tank.

[0014] The design of the housing as well as the offset arrangement of the first hydraulic connections and, in particular, the openings make it possible to install the device on the left, right or rear of the wall without requiring a minimum distance.

[0015] The hydraulic connections can preferably be coupled to the hydraulic pipes by means of a hydraulic plug connection.

[0016] Further embodiments of the invention are the subject of the subclaims.

[0017] Advantages and embodiments of the invention are explained in more detail below with reference to the drawing. Fig. 1 shows a schematic representation of a domestic appliance, Fig. 2 shows a schematic plan view of a domestic appliance of Fig. 1 , Fig. 3A to 3C show various views of a hydraulic module according to one aspect of the invention, Fig. 4A to 4C show various views of a hydraulic module according to a further aspect, Fig. 5A to 5C each show a view of a hydraulic module according to a further aspect, and Fig. 6A to 6C each show a view of a hydraulic module according to a further aspect.

[0018] Fig. 1 shows a schematic representation of a domestic appliance. The domestic appliance 100 has a domestic appliance element 110 (hot water tank, heat pump) and a hydraulic module 120, which is placed on the hydraulic element 110. The hydraulic module 120 serves to route the respective hydraulic connections of the module 110 to the outside. The hydraulic module 120 has four sides 121-124 and a top side 125.

[0019] Fig. 2 shows a schematic plan view of a home automation device from Fig. 1. Fig. 2 shows, in particular, a view of one side of the hydraulic module 120. In particular, first hydraulic connections 141-146 are shown. Some of the hydraulic connections 141-146 are coupled to hydraulic pipes 151-155. The hydraulic connections 141-146 are located in a straight line and diagonally in the area of ​​the housing of the hydraulic module 120. The hydraulic module has four sides 121-124 and a top side 125. The hydraulic connections 141-146 can be arranged on any of the sides 121-124 or on the top side 125.

[0020] Fig. 3A bis 3C show various views of a hydraulic module according to one aspect of the invention. In Fig. 3A is a perspective view of a hydraulic module 120. The hydraulic module has four sides 121 - 124 and a top 125. In the embodiment of Fig. 3A First hydraulic connections 141-146 are arranged, for example, on the top side 125. Alternatively, the hydraulic connections 141-146 can also be arranged on one of the other sides 121-124. The hydraulic connections 141-146 are each coupled to hydraulic pipes 151-156. In addition, a further second hydraulic connection 147 can be provided in a corner and coupled to a pipe 157.

[0021] On the side where the hydraulic connections 141-146 are located, a frame 130 with recesses or openings 131 is provided. The frame 130 can further have a diagonally extending strut 132. The openings 131 are designed to allow the hydraulic pipes 151-157 to pass through. This allows the hydraulic module 120 to be installed directly against a wall with the side on which the frame is located, without requiring a gap between the device and the wall. This is advantageous because it enables further installation options for the hydraulic module and, in particular, the building services device 100. Fig. 3B shows a top view of page 125 with the hydraulic connections 141 - 146. Fig. 3C shows a perspective side view (right in Fig. 3A ). Here, the frame 130 with the openings 131 and the hydraulic pipes 151 - 157 is shown.

[0022] In the example of Fig. 3A bis 3C the hydraulic pipes 151 - 156 run to the left.

[0023] In the aspect of Fig. 3B bis 3C The hydraulic connections 141-146 are arranged in a straight line and diagonally in the housing of the hydraulic unit 120. This arrangement has the advantage that the respective hydraulic pipes 151-156 can be laid individually or all in the same direction.

[0024] Optionally, the hydraulic connections 141 - 146 can be arranged in such a way that both a hydraulic pipe as in Fig. 3B shown, and a pipe arranged perpendicular to it can be coupled to the respective hydraulic connections. This allows for a very flexible arrangement of the hydraulic pipes 151 - 156.

[0025] The hydraulic connections 141 - 146 do not necessarily have to be located on a diagonal or straight line, but can also be provided in another geometric arrangement, as long as the hydraulic pipes can be connected in two directions.

[0026] Fig. 4A bis 4C show various views of a hydraulic module according to another aspect. The hydraulic module 120 of Fig. 4A bis 4C essentially corresponds to the hydraulic module of Fig. 3A bis 3C Only the arrangement of the hydraulic pipes 151–156 is different, namely rotated by 90°. This results in the hydraulic pipes then running toward the first side 120.

[0027] Fig. 5A bis 5C each show a view of a hydraulic module according to another aspect. The hydraulic module 120 according to the aspect of Fig. 5A bis 5C essentially corresponds to the hydraulic module according to Fig. 3A to 3D and Fig. 4A bis 4C . Only the arrangement of the hydraulic pipes 151 - 156 is different from the examples of Fig. 3A and Fig. 4A . According to Fig. 5A the hydraulic pipes 151 - 156 run to the left, ie towards the fourth side 124.

[0028] By comparing the hydraulic modules of Fig. 3A , Fig. 4A and Fig. 5A It can be seen that the diagonal arrangement of the respective hydraulic connections is advantageous and allows three different possibilities for the arrangement of the hydraulic pipes.

[0029] Fig. 6A bis 6C each show a view of a hydraulic module according to another aspect. The hydraulic module 120 of Fig. 6A essentially corresponds to the hydraulic module of Fig. 3A , 4A and 5A Only the design and orientation of the hydraulic pipes 151 - 156 is different from the other figures. Fig. 6A the hydraulic pipes run perpendicular to page 125.

[0030] This makes it possible with the hydraulic module 120 to provide four different configurations for the alignment of the hydraulic pipes.

[0031] In the Figuren 3A , 4A , 5A and 6A The hydraulic pipes are each shown substantially parallel. However, the hydraulic pipes may be configured differently, so that they do not all have to be parallel. For example, the hydraulic pipe 152 and the hydraulic pipe 155 may be oriented upwards, while the other hydraulic pipes are oriented to the left (as viewed from the hydraulic module of Fig. 3A ).

[0032] The hydraulic module 120, with its diagonal arrangement of hydraulic connections 141–146, can be used with various building services devices that have multiple hydraulic connections. These devices could be, for example, a heat pump, a hot water tank, an instantaneous water heater, etc. Bezugszeichenliste
