Description

The present invention relates to a valve apparatus for the

  filling a bathtub intended to be installed in its hole of over-

  solid, comprising a body that can be fixed against the wall of the bath, having a passage for feeding the bath with fresh water and a passage for evacuating the overflow of water from the bath and that can be connected outside the tub at least to a hose

  supply of fresh water and a discharge pipe.

  Such a fitting apparatus for filling a bath is described in German Offenlegungsschrift No. 35 09 311. It has a substantially conventional outlet overhanging the wall of the bath and directed towards the inside thereof. . The outlet port is maintained at a certain safety distance above the upper edge of the tub so that dirty water can not enter the fresh water supply system when, for For one reason or another, the overflow from the bathtub is clogged. With regard to the evacuation of the overflow of water, the body of the known structure of the valve apparatus has separate orifices situated approximately at the level of the overflow orifice of the bath. This valve apparatus of known structure is disadvantageous for several reasons. First, the channel and the body of the apparatus are relatively complicated in structure compared to the conventional structure of a fresh water outlet. Then, the exit directed towards the interior of the bath is considered disturbing for many users. Finally, since the outlet orifice itself is installed at a relatively high height above the upper edge of the bath, the height of the waterfall in the bath is relatively large,

  which gives rise to a noisy filling of it.

  In DE-PS 22 19 325, there is described a fitting apparatus for filling a bath whose exit orifice of fresh water is relatively low in the tub, below the orifice of overflow. full of it. However, there is no provision for adequate measures against the risk of dirty water entering the free water supply system,

  case of failure of the overflow system of the bathtub.

  DE-PS 26 53 754 also shows a fitting apparatus for filling a bath whose exit orifice is relatively low therein. There is installed a pressure tube aerator in anticipation of a clogging of the overflow system and a vacuum in the fresh water supply system. This design, however, does not prevent dirty water from entering the fresh water supply system when the dirty water in the bathtub gets too high (in case

  overflow blocked) without negative pressure in the fresh water supply system.

  In addition, the aerator employed in this case is relatively expensive.

  The object of the present invention is to provide a valve device of the type mentioned at the beginning, for filling a bath, characterized in that on the one hand, the fresh water outlet orifice itself is installed as low as possible in the bathtub and as close as possible to the wall of the bath and that, on the other hand, the penetration of dirty water into the fresh water supply system is prevented

  with certainty as simply as possible.

  For this purpose, the invention provides that: a) the fresh water supply passage comprises at least two chambers separated by a wall and interconnected in the upper part in the manner of an inverted siphon; (b) the upper end of the partition wall (19) is

  mounting position of the valve at a certain distance

  above the upper edge of the bathtub; (c) in the area of the fresh water supply passage located above the rim

  top of the bath, is an air intake.

  The reverse siphon provided according to the invention prevents the penetration of dirty water into the freshwater supply system by the mere fact that water rising as high in the bath will overflow first of it before be able to cross the partition wall forming part of the siphon and enter the "clean" zone. The air intake provided incidentally prevents such penetration under the effect of a possible depression in the supply system

fresh water.

  The air intake is usefully protected vis-à-vis the water flowing nearby, by means of a wall. It is thus avoided that the water does not come out

directly by the air intake.

  The advantages of the invention are particularly worthwhile when the body of the valve has a lower orifice simultaneously serving as a water supply port and an overflow orifice; therefore, common to

  passage of fresh water supply and the evacuation passage of the overflow of water.

  In this case, the body structure of the valve is

particularly simple.

  The principle of the invention requires that a part of the body of the valve is above the upper edge of the bath. This portion beyond the edge of the bath can then advantageously serve as a support for a receptacle or other similar objects. This aspect of the invention provides at the same time, for technical reasons known per se, an additional motivation for the vertical installation of the body of

  the faucet above the top edge of the bathtub.

  According to a particular structure of the invention, the body of the valve apparatus consists of two parts. The first part of the body is inserted into the overflow hole of the tub and is fixed against the wall of the tub, while the second part of the body is fixed on the first part of the body. Many bathtub filling valves of the type relating to the present invention have a control rod for the bath inverter. In this case, it is advantageous when the second part of the body is attached to the first part of the body by means of a hollow screw and when the hollow screw is coaxially traversed by the control rod. Such a measure makes a special contribution to simplifying

  body structure of the valve.

  The assembly of the two parts of the body of the valve against the wall of the bathtub is particularly simplified and much more stable when external "legs" are provided on the second part of the body, which serve to support this. against the wall of the bathtub. An example of structure of the valve for filling a bath according to the invention is described below in more detail with reference to the drawing. It is illustrated in Figure 1: a fitting apparatus for filling a bathtub integrated in the overflow orifice thereof, seen in vertical section;

  Figure 2: a section along the line II-II in Figure 1.

  In the overflow orifice 3 of a bath 2, shown only in part, there is inserted a valve for filling the bath, which is generally indicated by means of the

number 1.

  The body of the valve 1 for filling the bath 2 consists of two parts 4 and 5. The part 4 of the body on the right in Figure 1 has a hollow cylindrical collar 6, which is introduced into the overflow orifice 3 of the bath 2 from the outer side thereof, and a thrust flange 7, which sticks against the outside of the wall 8 of the bath 2. The end of the collar 6 opening into the bath 2 is provided with a male thread 9 for receiving a nut 10, which is screwed against the inner side of the wall 8 of the bath 2. The sealing of the assembly is provided by a seal 11 elastic inserted between the nut 10 and the wall 8 of the

bathtub 2.

  The lower part of the collar 6 and a connecting element 12 formed in the body part 4 define a bent chamber 13 by which the water of

  overflow may flow to the discharge pipe 14.

  The upper part of the part 4 of the body of the valve is traversed by a rectilinear orifice 15 in the outer end of which is screwed a pipe 16 for the supply of mixed water. The part 5 of the body of the valve installed on the inner side of the bath 2 has a circular connecting duct 17 which is inserted into the orifice 15 of the body part 4. An O-ring 18 inserted into the peripheral wall of the connecting pipe 17 makes it possible to seal the socket against the water flowing into the pipe.

connecting duct 17.

  The upper part of the part 5 of the body of the valve is divided into two chambers 30, 21 by a partition wall 19. These two chambers 30, 21 communicate with each other at the top and thus form a passage for water like an overturned siphon. The water flowing into the portion 5 of the body first enters the chamber 30, rises therein and then crosses the partition wall 19 whose upper end is

  at a certain safety distance, preferably about 20 mm,

  above the upper edge 20 of the bath 2. The water then reaches the chamber 21 of the part 5 of the body of the valve and escapes through a lower orifice 22 located very close to the wall 8 of the bathtub 2. The orifice 22 serves simultaneously as a water outlet orifice for filling the bath and overflow orifice. The water coming out of the orifice 22 almost immediately meets the wall 8 of the

  bath 2, along which it can then flow silently.

  The part 5 of the body is fixed to the body part 4 by means of a hollow screw 23 screwed into a square bracket formed in the right part 4 of the body. The part 5 of the tap apparatus further bears against the wall 8 of the bath 2 by means of a lower "leg" 25 and

of a superior "paw" 26.

  In the zone of the portion 5 of the body protruding from the upper edge 20 of the bath 2, there is still provided an air intake 27 protected from the influent water

  close by a wall 28 formed in the part 5 of the body.

  The upper end of the part 5 of the valve can also serve as a support for a receptacle 29 (shown in phantom

  mixed), for example a soap dish.

  FIG. 1 also shows a control rod 31 of the bath inverter 2, not shown in the drawing, which is actuated by means of a rotating handle 32 installed on the outside of the body part 5 and passes through the hollow screw 23 as well as part 4 of the body of -5-

the valve.

  The mode of operation of the valve apparatus described above is as follows: In normal operation, the water (generally mixed temperate water supplied by a mixer, not shown and installed separately, via the pipe 16) flows into the orifice 15 of the body part 4 and into the chambers 30 and 21 of the body part 5 and escapes through the orifice 22 in the bath 2. When the level of water from the bath 2 reaches the height of the tap, the water flows through the hole 22

  and the chamber 13 in the discharge or overflow pipe 14.

  The described structure of the path of the water within the part 5 of the body of the valve, in the manner of an inverted siphon provided with an air intake 27, makes it possible to prevent the penetration of water dirty in the fresh water supply system during the occurrence of various abnormal conditions

  of operation, which are known per se.

  For example, in case of failure of the overflow system of the bath (due to clogging of the discharge pipe 14 for example), the water rising in the chamber 21 of the part 5 of the body of the valve can never reach the chamber 30 and therefore in the supply line 16. Indeed, because of the safety distance provided between the upper end of the partition wall 19 and the upper edge 20 of the bath, the water will always overflow first from the bath 2 rather than

to enter the room 30.

  A possible depression in the fresh water distribution network can not cause any suction of dirty water, even when the lower orifice 22 is immersed in the water of the bath 2. The air intake 27 , which is in any case above the highest possible water level defined by the upper edge 20 of the bath 2, prevents in

  effect such a suction phenomenon.
