Definitions

  • the present invention relates to a hot water tank with an inner container, which has two opposite longitudinal side walls and two transverse side walls connected to them, and a container ceiling, wherein either two opposite longitudinal side walls or two opposite transverse side walls, preferably in one in relation to the height of the container and the width of the container
  • the area drawn in toward the center of the container is drawn in, the area of the longitudinal side walls or transverse side walls drawn in toward the center of the container having the shape of a funnel or cone on both sides and the funnel bottoms of the two funnels abutting each other in the center of the container and being supported against one another in a planar manner.
  • hot water tanks with inner containers of the type mentioned are known, for. B. from AT 386 069 (B).
  • the measure of drawing in the side walls of the container towards the center of the container so that they are supported against each other over a large area serves to stabilize the inner container of the hot water tank.
  • various functional parts are necessary which have to be mounted in or on the hot water tank, for example the control group with an adjusting device for setting the desired heating temperature.
  • the present invention has for its object to provide a hot water tank with an inner container of the type mentioned, in which the modules for the regulation and setting of the desired temperature are easy to assemble and are housed in a space-saving manner.
  • the solution to this problem is provided by a hot water tank with an inner container of the type mentioned with the characterizing features of the main claim.
  • the solution according to the invention takes advantage of the fact that, for reasons of stability, the inner container approximately in the Container center has a retracted area in the container side walls. This creates a funnel-shaped or conical free space in which an assembly necessary for the hot water tank can be accommodated. Furthermore, the fact that the funnel bottoms of the two funnels of the inner container are supported against one another and lie against one another in the area of a certain area makes it possible to accommodate a through hole there, which can then accommodate a fastening element and thus creates a fastening possibility for the installation of necessary assembly parts.
  • these assembly parts are preferably those which are associated with an electrical / electronic assembly for regulating and setting the desired heating temperature.
  • an electrical / electronic assembly for regulating and setting the desired heating temperature.
  • the present invention is not restricted to the aforementioned preferred electrical / electronic assembly.
  • a type of conical component can preferably be used and fastened to the funnel bottom by means of a fastening element which is received by the through hole. Further components necessary for the function of the hot water tank are then attached to this conical component. You only need one hole in the inner container, namely the through-hole, which is located where the funnel bottoms lie against each other, because it is understandable that it is not easy to drill into the wall of the inner container filled with water as intended for the attachment of additional components because this would result in tightness problems.
  • Hot water storage tanks of this type usually have insulation around the inner container and also have an outer container which serves to protect and disguise the assemblies and the inner container from the outside.
  • the minimum size of the entire hot water tank is determined by the volume of the inner tank and the layer thickness of the insulation required for thermal insulation, and if possible, all of the hot water tank assemblies that are also required should have space in this volume. In a hot water tank according to the invention, the size is optimized from this point of view.
  • a disc which can be plugged onto the outer region thereof is provided.
  • the electrical / electronic component and, if appropriate, further components can be fixed on this disk. You can also use the cone-shaped component to fix the outer tank of the hot water tank to the inner tank.
  • Said electrical / electronic component preferably comprises a control and / or a thermostat.
  • a rotatable control element is preferably used, which is operatively connected to the electrical / electronic component and which can be fixed to the conical component, for example by means of the disc which can be plugged onto the outer region thereof.
  • This control element is of course usually arranged on the outside of the outer container, while the control and the thermostat are on the inside of the outer container.
  • the control element is preferred arranged rotatably about an axis which corresponds to the central axis of the conical component.
  • the conical component can in a very simple manner, for. B. via a screw or the like which reaches through the through hole of the two adjacent funnel bottoms, can be fixed on the inner container.
  • the conical shape of the conical component has the meaning that it is adapted to the shape of the funnel of the inner container and the conical component is supported on the inner container.
  • the outer peripheral region of the conical component for plugging z. B. a disc can be used.
  • a pre-assembly namely the control assembly, the thermostat etc. can be mounted on the disc and then the disc can simply be plugged onto the conical component, so that the assembly is quick.
  • the control assembly which protrudes through the pane to the outside, preferably through an opening of the outer container, so that after the outer container has been placed on, the control element, e.g. B. can be simply plugged onto this axis of the control assembly by molded locking elements or the like.
  • numerous other mounting options are conceivable, which are within the scope of the principle according to the invention, according to which the funnels of the inner container are used for fastening mounting parts of the hot water tank.
  • the aforementioned conical component which can be used in one of the funnels of the inner container, does not have to have a continuous cone jacket, but can, for. B. be designed such that it has webs distributed over the circumference, which give this component an approximately conical shape, several such webs being connected at one end or also at both ends and smaller or larger openings between these webs available.
  • a conical component with four such webs, the webs then being located on the walls of the Support the funnel of the inner container. If the webs are connected in the region of the tip of the conical component, there is sufficient abutment there for a fastening element for attachment to the funnel bottom. On the outside, the disc can be placed on the ends of the webs.
  • the webs following the shape of the cone shell can be connected to one another at their outer end by a stabilizing ring web.
  • the inner container 30 for a hot water tank has channels formed on the inner container for the water inlet and outlet, specifically in the upper region an outlet channel 28 for the hot water and next to it an inlet channel 27 for the inlet Cold water.
  • This inlet channel 27 opens into a further channel 26, which is guided along the container 30 to the bottom of the container where it is deflected by 90 ° and then opens approximately horizontally into the inner container 30.
  • the cold water thus gets there into the inner container, heats up in it and leaves the container again as warm water via the channel 28 formed above.
  • the basic shape of the inner container 30 is derived from that of a cuboid and the inner container 30 has an approximately rectangular outer contour with somewhat rounded corner transition areas 33.
  • the container shape differs from a cuboid shape or box shape in that the two longitudinal side walls 31a, 31b, which are formed by the The two transverse side walls 32a, 32b are connected to one another, and are drawn inward in an approximately central region in such a way that there are two opposite funnels 20a, 20b, which extend so far towards the center that the funnel bottoms 20c abut each other and mutually in the region of support circular contact surface.
  • the two funnel bottoms here have a through hole 20d, so that here mounting parts can be fastened which are required for certain functions of the hot water tank, as will be explained below using an example.
  • the design of the two funnels 20a, 20b in the central region gives the inner container 30 improved rigidity and stability.
  • the flow of water from the lower half of the interior of the inner container in its upper half occurs in that the water flows through the connecting spaces 23, 24 which, like passages, form the right and left of the two funnels 20a, 20b (see FIG. 1).
  • the inner container 30 has an opening 42 in the lower region, which is arranged off-center on one side and has a circular outline. This opening 42 serves to introduce a heating coil through this opening into the inner container 30. Because the heating coil is off-center in introduces the inner container 30, a better circulation of the hot water in the inner container is achieved.
  • FIGS. 2 and 3 show an exploded view of a conical component 200, which is adapted in its outer contour to that of the funnel 20b.
  • This conical component 200 has four webs 200a, which are distributed around the circumference on one side of the component 200 and which are connected to one another on the outside of the conical component 200 by an annular web 200b.
  • the four webs 200a are connected to form a truncated cone 200c.
  • This truncated cone 200c has a bore 200d so that a driving pin 201 or a similar fastening element can be passed through this bore 200d and the bore 20d in the funnel base 20c in order to fasten the conical component 200 to the inner container 30, as shown in FIG. 3 is shown.
  • FIGS. 4 and 5 It can be seen here that the inner container 30 is embedded in an insulation 300 and this in turn is enclosed by an outer container 205 which covers the inner container 30 and which has an approximately cuboidal box shape.
  • the heating coil 41 which is inserted into the circular opening 42 of the inner container 30, can also be seen in FIGS. 4 and 5.
  • the conical component 200 accommodates in its interior in the outer area a control unit 202 with a thermostat, which is attached to the disk 203 on the inside thereof.
  • This disk 203 is in turn provided with webs on the circumference and is placed with these webs on the webs 200a and the ring web 200b of the conical component 200 and thus fastened to it.
  • a fastening axis 206 protrudes through a bore in the outer container 205, on which the rotatable axis then turns Control element 204 can be plugged in, by means of which the desired heating temperature can be set by acting on the control unit 202 from the outside of the outer container 205 with the hot water tank installed.
  • the corresponding switching operations are then carried out via a circuit, which is not shown in detail here, which bring about the heating of the heating coil 41 to the desired temperature.
  • Fig. 6 shows again the top view of the outer container 205 for the hot water tank according to the invention according to FIGS. 4 and 5, this outer container 205 being partially cut open so that the inner container 30 can be seen and the conical component 200 which is in the funnel 20b of the inner container 30 is inserted.
  • the control unit 202, the disk 203 attached to the conical component 200 and the rotatable control element 204 can also be seen here.
  • the connections for the outlet channel 28 and the inlet channel 27 emerging from the outer container 205 can be seen.
  • the conical component 200 can be seen in section in FIGS. 2 and 3. For a better understanding, a view of this conical component 200 in the direction of its axis is shown in FIG. 7 again. The four webs 200a and the truncated cone 200c can be seen.
  • the disk 203 is shown enlarged again in detail. It can be seen in Fig. 8 that the disc has openings and bores for assembly purposes and it can be seen from Fig. 9 that the edge of the disc 203 has a kind of groove 203a which, when the disc 203 is attached, the edge of the ring land 200b of the conical component 200 records.
