"Water tank with bottom cover "
5

The innovation relates to a water reservoir according to the preamble of claim 1.

Such water storage tanks are known from practice. They have a main tank, the water of which is heated,

for example, by a conventional heating system powered by fossil fuels or by a solar thermal heating system or by a combination of both, whereby the main tank in this case usually has a heat exchanger at the bottom, i.e. in the area of the coldest water,

which is connected to the solar thermal system and has a connection for the flow and return of the usual heating system. The domestic water tank is located in the uppermost area of the main tank and is heated by the warm water surrounding it in the main tank. The

The domestic water tank is usually designed in the form of an enamelled bladder and has a cold water inlet and an outlet for the heated domestic water required by the consumer.

Furthermore, it is known from practice to mount this domestic water tank on a riser pipe, which on the one hand serves to fix the domestic water tank in the main tank and on the other hand serves as a water inlet, whereby cold domestic water is introduced into the riser pipe at the bottom, which

is heated up over the height of the riser pipe and preheated before entering the actual domestic water tank. In this way, the mixing of the cold and warm domestic water within the domestic water tank is minimized and the stratification of the temperatures in the tank is as undisturbed as possible.

Domestic water tank enabled.

The known water reservoirs have a main tank with a cylindrical middle section and a curved upper and lower end cap. Due to the large number of connections and fittings, the manufacture of such a water reservoir is complex and accordingly

costly.

The innovation is based on the task of improving a generic water storage tank so that its production and maintenance are simplified and thus more cost-effective

becomes.

This problem underlying the innovation is solved by a water reservoir with the features of claim 1.

In other words, the innovation proposes to provide a bottom cover at the bottom of the main container, which is manufactured as a separate component and connected to the main container or its lower end cap. The bottom cover in turn

serves to fix the riser pipe and accommodate a cold water inflow, so that pre-assembled, relatively smaller units can be manufactured and finally assembled to form the entire water storage tank.

Advantageous embodiments of the innovation can be found in the subclaims.

An example of the innovation is explained in more detail below using the drawing.

In this case, 1 designates a water reservoir, which has a main tank 3 raised on feet 2. The main tank 3 consists of three main components, namely a cylindrical middle section and

each with a curved end cap, which is shaped approximately like a spherical segment.

In the lower part of the main tank 3, a spiral-shaped heat exchanger 4 is provided, which has two coaxially formed

coils and which can be connected to a preheating system, for example a solar thermal heating system, via two connections 5.

In the upper part of the main tank 3 there is a service water

container 6, which is designed in the form of an enamelled bubble, which is arranged concentrically in the main container 3.

The service water tank 6 is similar to the three-part main

tank 3 and has a head cover on its top, which is designed in several parts and which, among other things, has a connection for a hot water pipe, so that the consumer can demand the domestic water heated in the domestic water tank 6.

On its underside, the service water tank 6 has an opening that connects to a riser pipe 7. The riser pipe 7 is fixed with its lower end to a base cover 8, whereby the base cover 8 can be fitted with the same dimensions

measurements is designed like the head cover of the domestic water tank 6.

A nozzle 9 is arranged in the bottom cover 8, which has a connection thread at its lower end for connection to a cold water pipe, whereby the nozzle 9 forms a cold water inlet through which the cold water is introduced into the riser pipe 7 at the bottom as soon as hot service water is required from the service water tank 6 at the top. In order to ensure the temperature stratification within the riser pipe 7 and the

Service water tank 6 by the incoming cold water

In order to cause as little disturbance as possible, a baffle plate 10 is arranged within the riser pipe 7 at a distance in front of the mouth of the nozzle 9.

The construction of the lower bottom cover 8 in the form of an annular disk 11 extending around the riser pipe 7 and a deep-drawn plate 12 screwed to the annular disk 11 enables a cost-effective modular construction of the lower bottom cover 8 as well as simple production of the water reservoir 1 and, in particular, later simplified maintenance

connection of this domestic water storage tank 6 and the riser pipe 7.

Claims (3)

"Water storage tank with bottom cover" Protection claims: 1. Water storage tank for domestic water, with a main tank, and with a domestic water tank arranged in the upper region of the main tank, and with a riser pipe which extends from the lower region of the main tank to the underside of the domestic water tank and opens into it there, characterized in that the main tank has a bottom cover in its bottom which is designed as a separate component and to which the riser pipe is fixed, wherein a cold water inflow runs through the bottom cover into the riser pipe. 2. Water storage tank according to claim 1, characterized in that a baffle plate is arranged at a distance from the mouth opening of the cold water inlet. 3. Water storage tank according to claim 1 or 2, characterized in that the cold water inlet is designed as a nozzle which ends below the bottom cover and has a thread there for connecting a water pipe.
