Abstract

In a mixer tap for mixing cold and hot water, the hot water being supplied from a through-flow heater or a central hot water installation, boiler etc., it is provided for the purpose of matching, which can be carried out even by a layman, to hot water generating methods which can be carried out differently that, for optional operation using hot water from a through-flow heater or a hot water tank, boiler etc., a changeover valve is arranged in the cold water inlet which, in a first position, supplies an unrestricted cold water flow to the mixer tap and, in a second position, supplies a cold water flow to the mixer tap which is restricted in accordance with the performance of the through-flow heater.

Description

Mixer faucet with diverter unit

The invention relates to a mixer tap with the in the preamble of Claim 1 specified features.

Mixing taps are based on the different hot water generation for instantaneous water heater operation and for operation with central hot water generation systems known due to the recent significant increase in energy costs increasingly found that the central hot water systems that are often connected to the heating systems, switched off during the summer and the hot water requirement is covered by separate instantaneous water heaters. Since the hot water delivery capacity of a flow heater is usually very different is to that of a boiler or hot water storage chers, is the desired one Mixing or temperature control of the mixed water emerging from the mixer tap at least unsatisfactory for one type of hot water generation.

The invention is based on the object of creating a mixer tap, which in a simple manner, e.g. even by a layperson, it can be switched to each used hot water generation processes.

This object is achieved according to the invention by the in the characterizing part of claim 1 specified features solved. Further refinements of the invention are given in claims 2-5.

The advantages achieved with the invention are in particular: that by changing the switching valve, e.g. by means of a screwdriver, Coin, etc., an optimal operation of the mixer with the different Hot water generation systems is made possible. With the measures according to the invention it is also made possible for non-specialists, e.g. apartment owners, during during summer operation with an instantaneous water heater and during winter operation with a central water supply system or boiler, the mixer tap this sen To optimally adapt to the circumstances.

An embodiment of the invention is shown in the drawing in schematic Way and is described in more detail below. It shows Figure 1 a Mixer tap in plan view; FIG. 2 shows a throttle valve in the open position; FIG. 3 the throttle valve according to FIG. 2 in the throttle position.

The sanitary mixer tap 1 shown in the drawing is with a connection piece 2 for the cold water and a connection piece 3 for the hot water equipped and is by means of union nut screw connections 6 on the respective inflow lines attached. In the body of the mixer tap 1 control or regulating elements are arranged (not shown in the drawing) ', with which the inflowing cold and warm water mixed in a desired ratio or having a certain temperature Mixed water is generated, which via an outlet nozzle 4 into a wash basin, Bathtub etc. is delivered.

In the connection piece 2 for cold water there is a throttle valve as a changeover valve 5 provided. As can be seen in particular from FIGS. 2 and 3, this exists Throttle valve 5 essentially consists of one arranged in the inlet connection 2 Throttle valve 51, which is in an unthrottled position according to Figure 2 or by a Rotation by 900 can be brought into a throttle position according to FIG. 3. In the The throttle position is essentially the flow cross-section of the connecting piece locked and only a much smaller passage opening 52 can according to the amount of cold water corresponding to the hot water delivery capacity of the instantaneous water heater flow into the mixer tap.

The conversion of the throttle valve 5 can be done by attaching a Screwdriver, dances, etc. into a slot protruding from the connecting piece 2 53 take place.

To adapt to instantaneous water heaters with different hot water delivery rates or in particular to the pressure prevailing in the cold water supply network, the Throttle opening expediently adjustable or by a flow regulator or flow restrictors are formed.

In the exemplary embodiment of the drawing, the switching valve is in the cold water connection of the mixer tap. In particular for subsequent However, the changeover valve can also advantageously be converted in the cold water supply line or in the connection fitting, the so-called S-connection piece.

Claims (5)

CLAIMS 1. Mixer tap for mixing cold and hot water, whereby that of a water heater or a central hot water system, boiler etc. is supplied, characterized in that for optional operation with hot water from a water heater or hot water storage tank in the cold water inlet, a changeover valve is essentially arranged that in a first position is one in / ung one, that in unthrottled cold water inflow and in a second position one accordingly the output of the instantaneous water heater, the cold water flow to the mixer tap is reduced (1) feeds. 2. Mixer faucet according to claim 1, characterized in that the Switching valve is designed as a throttle valve (5) and the throttle valve (51) a throttle opening designed according to the capacity of the flow heater (52) has. 3. Mixer tap according to Claims 1 and 2, characterized in that that the throttle opening (52) is adjustable in the passage cross section. 4. Mixer faucet according to claims 1 to 3, characterized in that that the throttle opening (52) from a flow regulator or flow limiter is formed. 5. Mixer faucet according to claims 1 to 4, characterized in that that the switching valve in the connection piece (2) of the mixer tap (1) for cold water or is arranged in the connection piece of the cold water supply line.
