Description

[0001] The invention relates to a thermal device according to the preamble of patent claim 1.

[0002] A thermal device of the type mentioned above is known from patent document DE 10 2018 132 504 A1. This device consists of a housing, an insulating body arranged in the housing, a receiving area formed on the insulating body, and a functional component of the thermal device arranged in the receiving area and having a longitudinal axis. Looking more closely, this device is a hot water tank with an insulating body made of particle foam (in particular EPP), to which, for example, a pipe is fixed as a functional component, in particular by clipping.

[0003] The invention is based on the object of improving a thermal device of the type mentioned above. In particular, the positioning of the functional component during assembly is to be facilitated and the position or orientation of the functional component is to be secured over the long term during operation of the device.

[0004] This object is achieved with a thermal device of the type mentioned at the outset by the features listed in the characterising part of patent claim 1.

[0005] According to the invention, it is therefore provided that, on the one hand, a first form-locking element is provided on the receiving area and, on the other hand, a second form-locking element is provided on the functional component, which fits together with the first form-locking element in order to fix it in the direction of its longitudinal axis.

[0006] In other words, the solution according to the invention is characterized by the fact that, in addition to the already known radial fixation, an axial fixation of the functional component to the insulating body is now also provided in the receiving area. This facilitates installation and also ensures, in the long term, that the functional component does not slip during operation of the thermal device. Furthermore, no additional fixation elements are necessary because these are incorporated into the insulating body.

[0007] Other advantageous developments of the thermal device according to the invention emerge from the dependent patent claims.

[0008] The thermal device according to the invention, including its advantageous developments according to the dependent patent claims, is explained in more detail below with reference to the drawings of two exemplary embodiments.

[0009] It shows Fig. 1 shows a perspective view of the thermal device according to the invention (partially) with the counter-insulating body not yet mounted; Fig. 2 perspective view of the insulation body according to Fig. 1 as a single part; Fig. 3 perspective view of the counter insulation body according to Fig. 1 as a single part; and Fig. 4 shows in perspective a further embodiment of the thermal device according to the invention (partially) with a total of three plugs, one of which serves only for sealing and the other two are provided with a through-opening for a cable.

[0010] The thermal device, in particular a heater, shown in the figures consists of a housing 1, an insulating body 2 arranged in the housing 1, a receiving area 2.1 formed on the insulating body 2 and a functional component 3 of the thermal device arranged in the receiving area 2.1 and having a longitudinal axis 3.1. Fig. 1 and Fig. 4 shows the rear of a new VITOCAL appliance from the applicant, more precisely, the rear of an indoor unit of a heat pump, with which the appliance faces a wall of its installation room. A hot water cylinder is preferably arranged in the preferably cuboid-shaped housing 1 (but not separately shown), among other things. Furthermore, it is preferably provided that the insulating body 2 is positively connected to the housing 1, preferably clipped onto the housing 1. Looking at it in more detail, it is preferably provided that the insulating body 2 is plugged on and then clamped by a rear wall. This enables tool-free installation of the insulating body 2.

[0011] What is essential for the solution according to the invention is that, on the one hand, a first form-locking element 2.1.1 is provided on the receiving area 2.1 and, on the other hand, a second form-locking element 3.2 is provided on the functional component 3 for fixing it in the direction of its longitudinal axis 3.1, which matches the first form-locking element 2.1.1. As already explained at the beginning, this simplifies the assembly of the functional component on the one hand (otherwise typically required pipe clips can be omitted), and on the other hand, its position within the housing 1 is guaranteed in the long term. As shown, it is particularly preferably provided that the longitudinal axis 3.1 of the functional component 3 is arranged or designed to run vertically in the receiving area 2.1.

[0012] Looking at all of this in more detail, it is particularly preferably provided that the functional component 3 is at least partially arranged between the said insulating body 2 and a counter-insulating body 4. This counter-insulating body 4, together with the insulating body 2, serves to create a liquid-tight closure for the piping and, if applicable, the cabling (see also further below) within the housing 1, which closure prevents the flow of moist air and is particularly advantageous for significantly reducing the amount of condensate that accumulates within the housing, particularly during cooling. Furthermore, it is particularly preferably provided that either the insulating body 2 and / or the counter-insulating body 4 are or are formed from a foam material, preferably from a particle foam, particularly preferably from expanded polypropylene.The density of the foam material is preferably between 30 and 90 grams per liter, particularly preferably 60 grams per liter.

[0013] As can be seen in particular from the Fig. 2 and Fig. 3, it is further preferably provided that at least three, preferably at least five, particularly preferably at least seven, receiving areas 2.1 for a plurality of functional components 3 are arranged, preferably in a horizontally extending row, optionally on the insulating body 2 and / or on the counter-insulating body 4.

[0014] Furthermore, it is preferably provided that the counter-insulating body 4 (with corresponding lateral overlapping areas) is designed to at least partially enclose the insulating body 2.

[0015] Looking at it in more detail, it is preferably provided that, on the one hand, a third form-locking element 4.3 is provided on the counter-insulating body 4, and, on the other hand, a fourth form-locking element 3.4, which matches the third form-locking element 4.3, is provided on the functional component 3. In this way, the functional component 3 is completely fixed between the insulating body 2 and the counter-insulating body 4.

[0016] Furthermore, it is preferably provided that a fixing section at least partially enclosing the functional component 3 forms the second and fourth form-locking elements 3.2, 3.4. The aforementioned axial fixation is thus realized or ensured not only between the functional component 3 and the insulating body 2, but also between the functional component 3 and the counter-insulating body 4.

[0017] Looking at all this in more detail, it is preferably provided that the functional component 3 is designed either as a tube or as a plug.

[0018] As from Fig. As can be seen in Figure 1, it is particularly preferred that the second form-locking element 3.2 and / or the fourth form-locking element 3.4 be configured as a compression portion of the pipe, which could also be called a flanging. This compression portion then preferably forms the aforementioned fixing section, which ensures the axial fixation of the functional component 3.

[0019] The above-mentioned plug is in Fig. 4. It serves either to completely seal the receiving area 2.1 in a liquid-tight manner or to create a likewise liquid-tight passage for a cable or a line of the thermal device (liquid-tight also includes avoiding or preventing the passage of moist air). For the latter option, it is preferably provided that the plug is provided with a passage opening 3.3 for an additional functional component 3.5, in particular the said cable. The passage opening 3.3 can preferably and optionally lie so tightly against the cable that the latter cannot slip axially, or the plug is directly connected to the cable in a material-to-material bond, i.e. the passage opening is created by separating the cable and plug. Furthermore, it is preferably provided that the second form-fitting element 3 facing the insulating body 22 and / or the fourth form-locking element 3.4 facing the counter-insulating body 4 is formed by an edge of the plug. Furthermore, the plug can preferably be formed as shown in . Fig. 4, have at least two form-locking elements 3.2 of different diameters in order to be able to be positioned in receiving areas 2.1 of different diameters (for thicker and thinner pipes).

[0020] Furthermore, it is preferably provided that a contact area 3.6 shaped like a half inner cylinder is provided for the functional component 3 on the insulating body 2 and / or on the counter-insulating body 4, optionally above and / or below optionally the first and / or third form-locking element 2.1.1, 4.3. Furthermore, it is preferably provided that optionally the first form-locking element 2.1.1 and / or the third form-locking element 4.3 is formed as a preferably semi-annular groove on the insulating body 2 or on the counter-insulating body 4.

[0021] Expressed again in other words, for the aforementioned condensate reduction, it is particularly preferred that the insulating body 2 and the counter-insulating body 4 are designed to accommodate the functional component 3 and / or the additional functional component 3.5 (i.e., for example, a cable with a plug-like injection molding) between them in a liquid-tight manner.

[0022] Furthermore, it is particularly preferred that connecting elements 2.2, 4.2 which fit together and are designed for preferably horizontal mutual attachment to one another are provided on the insulating body 2 and the counter-insulating body 4.

[0023] For particularly good handling and in particular to reduce the risk of injury when assembling the thermal device according to the invention, reference is made to Fig.1, at least one grip element 4.1, preferably formed from its own material, is also provided on the counter-insulating body 4. The grip element 4.1 is particularly preferably designed as a projection arranged in a recess on the counter-insulating body 4.

[0024] In addition, a cable bushing 1.1, preferably made of a rubber-elastic material, in particular ethylene-propylene-diene rubber (EPDM), is preferably also provided on the housing 1.

[0025] The assembly of the thermal device according to the invention is carried out as follows: First, the insulation body 2 is secured to the housing 1 by snapping it into place. The pipes are then guided through the receiving areas 2.1 and axially secured there, preferably using compression joints (or preferably flanges). The lines or cables are secured in the same way using plugs. Unused receiving areas 2.1 can also be closed with a plug. Finally, the counter-insulation body 4 is pressed onto the insulation body 2 using the grip element 4.1, of which two are preferably provided, so that the connecting elements 2.2 and 4.2 form a positive connection, thus ensuring a liquid-tight seal. This allows the entire system to be assembled without tools. No screw connections or similar are necessary; fastening is achieved exclusively through positive geometries.
