of the control unit via an air hose with which the The bubble grate inserted in the bathtub is always a source of danger when removing the bubble grate from the bath water via the air hose the water absorbed by the switched off soda grate to the control unit can flow back.

The water flowing back into the control unit not only adversely affects the electrical devices in the control unit, it also creates a dangerous creepage distance from the electrical connections in the control unit via the air hose to the soda grid and thus to the bath water. When the air bubble massage device is started up again, the Bathers endangered.

The dangerous effect of these creepage distances can be prevented by all functional units in the device housing with a safe extra-low voltage operated by a separate power supply is derived with a safety transformer. This power supply unit is separated from the device housing and is only connected to the device housing via a connecting cable, "via the connecting cable only transmit the extra-low voltage.

This known air bubble massage device offers the advantage that the device housing with the functional units and the operating elements can be set up within reach of the bather so that it can be operated directly from the bathtub can. The power supply unit with the safety transformer must, however, be firmly attached to the wall out of the bather's reach will. The safety for the bather is given even when the device housing is in the bathtub Water falls.

This "known air bubble massager requires a relatively large amount of money powerful safety transformer, as it has to feed all functional units. This safety transformer therefore becomes large, heavy and also expensive. In addition, "the Eunktioxs units are designed to save space with good efficiency, especially for a low voltage, which should preferably be below 24 volts, considerable Difficulties, especially for, the fan.

You can also avoid the backflow of the water from the soda grate to the control unit by the fact that the soda roaster with the Air hose connecting the control unit via a holder directly is attached below the ceiling in the bathroom. When removing the bubble grate from the bathtub, this can happen from the bubble grate absorbed water then usually never pass this highest connection point determined by the holder, since no part of the bubble grate in the bathroom can be lifted higher. However, there is no clear certainty if the The soda grid has absorbed a lot of water and is hung up with a jerk, whereby the air hose moves strongly up to the holder will. If the holder itself is designed as a hook for hanging up the split grate, then these assembly instructions also makes hanging up the soda grate difficult.

It is the object of the invention to design a device of the type mentioned at the outset in such a way that it is revealing ! Routing of the air hose between the control unit and the soda grate, the backflow of water from the soda grate to the The control unit and the associated risk to the bather is switched off via electrical creepage distances.

Most expediently, this water collecting container 10 is included in the connection between the soda grate and the control device, preferably in the air hose. The water collecting container 10 forms a receiving space 11 into which the two connecting pieces 12 and 13 open. The connection piece 12 for the air tube section leading to the soda grate opens into the water collecting container 10 via the inlet opening 17 in the bottom area of the receiving space 11, while the connection clip 13 for the. vol ~. Control unit coming air hose section in the upper area of the water collecting container 10 opens into the receiving space 11. This ensures that the water can only enter the connecting tube 13 via the inlet opening 18 after the receiving space 11 has been filled. If the receiving space 11 is sufficiently large, however, this is reliably prevented. The baffle or shut-off wall 16 makes it even more difficult for water to flow into the connecting piece ^x i3. If the soda grate is put back into the bathtub, the water can automatically flow out of the receiving space 11 again, the switched-on compressed air still assisting this flow of water.

Like Tig. 1 shows, the visible front wall of the water collecting container 10 is preferably made of transparent material, see above that the filling level of the water collecting container can be seen.

As a further safety precaution, the upper area of the water collecting container 10 can be closed with a closure flap 14 be detachable along the edge 15 on the water collecting container 10 is attached. This closure flap 14 can via per se known East elements, which in the locking grooves 19 snap into place, be held on the water collecting container 10.

the level of the water in the receiving space 11 exceeds the Edge 15, then the water exercises on the flap 14 a Force that ultimately leads to the cancellation of the locking connection. This means that even with unexpectedly large amounts of back-flowing water ensures that nothing can flow through the connection piece 13 to the control unit. The shutter 14 opens the water collecting container 10 as a safety valve and lets go of a certain level Leak water into the open air.

In the embodiment according to Pig. 3 and 4 are the connecting pieces 12 and 13 formed on a housing upper part 22, the can be connected to the lower housing part 20 via locking rims 23. This two-part housing takes up a separate water collection container 21 vertically adjustable. The water flowing in via the connection piece 12 reaches this separate one Water collecting container 21, as the partition wall 34 with the passage 35 in the upper part 22 a decoupling to the connection piece brings. The separate water collecting container 21 is pressed against the stop 36 of the upper part 22 via the compression spring 29. The water collecting container 21 merges into a pot-like extension 27 with lateral outlet slots 28 in the bottom area * This approach 27 is in a provided with an outlet opening 25 guide sleeve 24 of the lower part 20 gefühx-c. the Compression spring 29, which is placed around the guide sleeve 24, is supported on the outside of the bottom of the water collecting container 21 and is while doing the same through the annular groove 26 in the bottom. If the water collecting container 21 is empty, then he takes the one shown Position. The outlet slots 28 of the extension 27 are closed by the guide sleeve 24 of the lower part 20.

If the water collecting container 21 takes up water, then the compression spring 29 is compressed more and more , "until finally, the extension 2" emerges from the guide sleeve 24. The outlet slots 28 are released and the collected water flows off again separate vertically adjustable water collecting container 21 can therefore only hold a certain amount of water and, depending on the amount of water absorbed, controls the water outlet which is formed by the extension 27 and the guide sleeve 24.

A plug-in attachment 33 is formed on the lower part 20 and can be plugged into a plug-in receptacle 31 of a holder 30 that can be fastened to the wall. This holder 30 is provided with a hook 32 for hanging up the soda grate.

In the embodiment of FIG. 5, the separate water collecting container is 21 held in the upper part 22 via resilient locking tongues 37 with locking bevels 38. This starting position corresponds to the closed position of the water outlet from extension 27 and guide sleeve 24.

If the water collecting container 21 takes up water _t then the latching connection between the latching tongues 37 and the upper housing part 22 is triggered at a predetermined amount of water. The water collecting container 21 adjusts vertically until it stands on the floor of the lower part 20. The outlet slots 28 are released and all of the collected water can flow out of the water collecting container 21 without the latter changing its position. This bistable setting of the water collecting container 21 remains; the optimal security.

Before starting up again, the water collecting container 21 about his approach 27 should be impressed so that the Snap locking tongues 37 back into place on upper part 22. In this lock Position is an unintentional leakage of pressure air prevented via the now closed water outlet.

How based on the Pig. 6 is shown, the connecting pieces end. for example 12, of the upper part 22 in a sleeve 39 'which f to the outside) diameter of the air tube according to Pig. 8 is adapted. The air hose is composed of the two hoses 44 and 46 which are arranged coaxially to one another and which are connected to one another by radially extending webs 45 and thus divide axially extending cavities 47. The sleeve 39 carries plug fingers 40, which are matched in size and distribution to the cavities 47 of the air hose.

The plug fingers 40 and the sleeve 39 form a receptacle 43 for the outer hose 44-, while the slots 41 between the plug fingers 40 matched to the webs 45 of the air hose are. On the inner wall, the sleeve 39 carries bead-like extensions 42 which the inserted hose 44 against the slots ■ * - '41 and thus brace against the plug-in finger 40, while the Insert finger 40 deeper into the cavities 47 of the air hose are introduced.

The air hose can be shortened as required at the place of use and fastened to the connecting piece 12 without its own connecting piece. The length of the air hose sections can therefore be optimally selected at the place of use. This has the advantage that the Pressure and heat loss between the control unit and the bubble grate can be kept small.
