Description

The invention relates to a device for disinfecting and / or decalcifying particular showerheads and their flexible leads, which is particularly suitable for retrofitting existing showers.

From the DE 20 2013 011 711 U1 is a cleaning head, in particular shower head, comprising at least one formed within a base holder Wasserzuführleitung for passing water, wherein the water supply line opens in a spray head for discharging the water, known. The water supply line has a first part line and a second part line, wherein an engageable in the water supply line valve locking device is configured such that in a first operating state of the valve locking device, a flow path is blocked by means of the valve locking device through the second part line, and the valve locking device is further configured in that, in a second operating state of the valve blocking device, a flow path through the valve blocking device is blocked by the first part line, and at least in places at least one water softening agent for descaling the water is arranged in the second part line or the first part line.

The disadvantage is that only the shower head is subjected to a descaling.

The object of the invention is to subject both the shower head and the flexible supply of a decalcification and disinfection. This should be suitable in an advantageous embodiment as a retrofit kit for existing showers.

This object is achieved with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

The inventive device for descaling and / or disinfecting shower facilities with a mixer, which has a cold and a hot water connection and an outlet for the shower and a faucet firmly connected to the mixer tap, provides that between one of the water connections and the mixer tap a valve block is arranged, wherein the valve block on the input side has a 2-way valve with a switching lever to direct in a first switching position the water flow directly and in a second circuit via a bypass to the mixer tap and in the bypass a supply line for a Descaling agent and / or a disinfectant opens and the mouth of the supply line in the bypass downstream of a check valve, which prevents an inlet of water at the first switching position in the bypass.

With the proposed device, the decalcifying agent and / or the disinfectant can be introduced into the mixer tap by utilizing the flow of water and can then disinfect both the faucet and the flexible supply line with attached shower head and / or descale as needed.

Furthermore, existing showers can be retrofitted by mounting the valve block between the water connection on the wall and the mixer tap. The resulting distance between the other water connection and the mixer tap can be bridged by a spacer. So it is not necessary to use new mixer taps. Of course, the valve block can also be arranged behind a fitting holder.

Preferably, the valve block is arranged in the hot water supply, since it is to be expected with greater nucleation and the effectiveness of descaling agents and / or disinfectants is improved.

A further advantageous embodiment provides that the supply line for descaling and / or disinfecting agent is detachably connected to the valve block. This is particularly important for an embodiment in which the decalcifying and / or disinfecting agent is arranged in a top container on the valve block. The attachment can be removed so does not interfere when it is not needed.

In hospitals, etc. can be used in this way a top container in the disinfection / decalcification by the staff for several showers one after the other.

In order to introduce the descaling and / or disinfecting agent from the attachment container in the bypass, which is under water pressure, various designs are provided.

A first solution works on the principle of water jet pump by the flowing water generates a negative pressure, which sucks the disinfectant and / or descaling agent from the attachment container.

A second solution provides that in parallel to the supply line for descaling and / or disinfectant in the bypass a line for water from the bypass in the attachment container is present. The line for water from the bypass should be located opposite the supply line for decalcifying and / or disinfectant into the attachment container.

In a third embodiment, the decalcifying and / or disinfecting agent supply line or the topping bin have a pumping device to urge descaling and / or disinfecting agents into the bypass.

A further advantageous embodiment provides that the 2-way valve and the supply line for decalcifying and / or disinfecting agent are coupled to each other such that when connecting the supply line for descaling and / or disinfecting agent to the bypass or even with the second -Wege valve the change-over lever of the 2-way valve is switched to the switching position two and when releasing the supply line in the switching position one. This means that the mixer tap is supplied exclusively via the direct connections to the water connections without the supply line or attachment.

The invention will be explained with reference to the drawing.

• 1 shows a mounted on the wall A mixer 5, which has a cold and a hot water connection 2, 3 and has a spout 7 for the shower and a fixed to the mixer tap faucet.

Between the water connection 3 for hot water and the mixer 5 is a valve block 4 arranged.

The valve block 4 has on the input side a 2-way valve 9) with a switching lever, in a first switching position, the water flow directly and in a second switching position via a bypass 8th to the mixer tap 5 to lead. In the bypass 8th opens a supply line for a descaling agent and / or a disinfectant from a top container 11 , The mouth of the supply line in the bypass 8th is a check valve 10 downstream, which has an inlet of water at the first switching position in the bypass 8th prevented.

The user of the shower system can select 11 connected by attaching the 2-way valve 9, if he desires a disinfection / descaling or shower / wash water should leave the mixer tap. By switching the 2-way valve 9 after disinfection / decalcification the mixer tap 5 rinsed, preferably by passing the water over the outlet 7 is drained for the shower.

In an advantageous embodiment, it is provided that the supply line for descaling and / or disinfectant releasably connected to the valve block 4 connected is. The 2 -Wege valve 9 and the supply line for descaling and / or disinfectant should be coupled together so that when connecting the supply line for descaling and / or disinfectant with the bypass 8th or even with the 2-way valve 9, the switching lever of the 2-way valve 9 in the switching position two - supply line via the bypass 8th - is switched and when releasing the supply line in the switching position one - direct hot water supply. This means that without supply line or attachment container 11 the mixer tap 5 is supplied exclusively via the direct connections to the water connections 2, 3.

2 shows an embodiment in which the valve block 4 is arranged behind a fitting holder.
