Description Electric instantaneous water heater The invention relates to an electrical DüfCh läüfef &pgr; ItZeT &Sgr;&udigr;&Ggr;&Iacgr;&iacgr;5&pgr;&Iacgr;&iacgr;&iacgr;&udiagr;13&udiagr;&Ggr;&igr; Lr &Pgr; * S &Ggr; ~ O d S r

Above-sink installation with a cold water inlet pipe section and a hot water outlet pipe section, the ends of which are at two spaced-apart installation points.

When installing an instantaneous water heater, the cold water connection is usually located to the right of the hot water connection on the wall on which the instantaneous water heater is to be mounted. Accordingly, the end of the cold water inlet pipe for the instantaneous water heater is located to the right of the end of the hot water outlet pipe.

In the case of an instantaneous water heater designed for installation above the counter, the ends of the pipe sections to be connected are provided on the underside of the heater. In the case of an under-counter installation, where the instantaneous water heater is installed upside down, the end of the cold water inlet pipe section is to the left of the hot water outlet pipe section. This means that the instantaneous water heater cannot be connected directly to the connection points, as this would involve an impermissible reversal of the flow direction of the instantaneous water heater. In order to avoid this, considerable additional assembly work is necessary according to the state of the art.

The object of the invention is to propose a flow heater in which the ends of the pipe sections are at the top when installed under the counter and the ends of the pipe sections are at the top when installed above the counter.

of the pipe sections are at the bottom, with in both cases the end of the cold water supply pipe section being to the right of the end of the hot water drain pipe section.

According to the invention, the above object is achieved in that the two pipe sections are cranked and can be pivoted so that the end of each of the two pipe sections can be pivoted to each of the two mounting points.

reduces the space requirement.

Advantageous further developments of the invention result from the subclaims and the following description of an exemplary embodiment. The drawing shows:

Figure 1 is a view of a continuous flow heater,

Figure 2 is a view of the instantaneous water heater along the line 11-11 of Figure 1 and

Figure 3 is a view of the instantaneous water heater along the line III-III of Figure 1.

In a continuous flow heater, two U-shaped pipe sections (1, 2) are arranged in parallel planes. An electric tubular heater (3) runs coaxially in each of the pipe sections (1, 2). The pipe sections (1, 2) are connected at one end to a cross pipe (4).

III · ·

The pipe section (1) is connected via a bent intermediate pipe (5) to a connector (6) which lies in a central plane of the instantaneous water heater. The connector (6) carries a double-cranked cold water inlet pipe section (7) which can be pivoted on the connector (6) about an axis (8) lying in the central plane. A free end (9) of the inlet pipe section (7) intended for connecting the instantaneous water heater lies outside the housing of the instantaneous water heater.

A Venturi nozzle is designed in the connector (6) which enables the flow-dependent switching of the tubular heaters (3).

The end of the U-shaped pipe section (2) facing away from the cross pipe (A) is led via another intermediate pipe (D) to another connector (1), which is also arranged in the central plane. A double-cranked hot water drain pipe section (2) is arranged on the connector (1), which can be pivoted about an axis (di) that is also in the central plane. The two axes (8, 13) run parallel to each other and are spaced apart (A). A free end (H) of the drain pipe section (2) is also located outside the housing of the instantaneous water heater.

The ends (9,14) are assigned to two mounting points (5,16) that are at a distance (B). A cold water connection to a water network is provided at the right mounting point (5). A hot water connection that leads to a tap is provided at the left mounting point (16).

In the position of the pipe sections (7,12) shown in the figures, the instantaneous water heater is designed for above-counter installation, with the ends (9,14) at the bottom.

If the installation of the instantaneous water heater is to take place with the ends (9,14) at the top, then with the swivel position of the pipe sections (7, 12) shown in the figures, the end (9) is initially to the left of the end (14). This does not correspond to the arrangement of the water connections, since the cold water connection on the assembly wall is to the right of the hot water connection. In order to maintain the correct flow direction (S), the cold water inlet pipe section (7) is now swiveled by around 180° around the axis (8) and the hot water outlet pipe section (12) is swiveled by around 180° around the axis (13). The end (9) is now where the end (14) was previously. The end (H) Is where the end (9) was previously. The instantaneous water heater is now ready to be connected to the mounting points (15,16), whereby the correct flow direction (S) is maintained.

The pipe sections (7,12) are bent differently so that they can both be swivelled forward without colliding with one another. In Figure 2, the swivelling movements are indicated by the arrows (V).
