Detailed description of the preferred embodiments

Fig. 2 is a view of a bath 50,

30 which incorporates the present invention.

In this case, the nozzles 32 are not of the venturi type, although they could be if so desired.
35

The bathtub 30 is preferably made of dimensionally stable plastic material, although in principle they are also made of cast iron or steel

with burned-on porcelain (porcelainised) could be. The bathtub has a conventional waste water outlet 36 and an overflow 38. The used water flows through a waste water outlet unit 40, which is shown below with reference to FIG is described, and by an approach 42, which the ..; Overflow outlet accommodates in a conventional U-water supply

final outlet 44. A relatively low altitude

can be maintained under the sewer opening 36. if

there is no overflow attachment 42, the water flow depends

f 10 End 44 directly on unit 40.

The nozzles 32 are in the bath 50 shown in FIG

connected by vertical pipe sections 52 to a larger channel part 54 which runs below the length of the bath. That Channel part is designed as a rigid plastic extrusion. The part 54 has a section as shown in Figure 3 and, as can be seen, has an approximate one rectangular shape, but the bottom surface 54 slopes downwards towards the center and the side walls close also make a small angle with the vertical. In the channel part 54 is a circular pipe section 60, which is molded as a unit with the channel part so as to face one surface, in this case the upper surface 62 lie. Thus it can be seen that there are two separate fluid channels formed in the channel part, viz the channel 64 formed by the tube 60 and the channel 66 which runs through the remainder of the space in the channel part 54 is formed.

4 shows the channel part 54 with its pump-side end parts 70 and its end parts 72 on the waste water outlet side.

The pump-side end part 70 is shown in detail in FIG

% shown. Part 70 sits on the end of the canal part.

|: les 54 and is attached to this by means of a suitable adhesive

f 35 attached. The part 70 therefore has internal and external

ί flanges 74 and 76, which between them a channel 78

Form S, in which the end of the channel part was added

t β · c ι * <■ ■

• ι ti «· ·

is- The end of the tube 60 is on a tubular section 80 tightly attached and other tubular section 82 is adjacent and communicates with the space or a channel 66 in the channel part. The tubular Portions 80 and 82 are connected to the inlet and outlet of the pump 16, respectively. The pump 16 can be in a usually vertical manner Orientation be arranged as shown in Fig.2, in which they are more clearly arranged in the available Space at the end of the bathtub.

At the other end of the sewer part, near the sewer outlet, the end portion 72 is provided to provide a connection between the space 64 in the pipe or conduit 60 and a To create chamber 84 which is below the sewage outlet of the bath. The end part 72 is exactly in Fig.6 and shown. The space 66 is apart from a small hole 86 which is at the deepest point in the space 66, i. lies in the middle of the bottom surface 56 of the channel part, blocked by the end part 72. The end part is on the channel part 54 is attached in a manner like the end piece 70.

The pump can dispense water from the bath's waste outlet via chamber 84 and pipe 60 out into space 66 in pump the canal part. This space is then connected to the vertical pipe sections 52. This connection is achieved by means of fixing nozzles shown in FIG. These nozzles have flanges 92, which on two opposite Parts are cut off so that the flange recesses 94 on the upper and lower edges of the side walls 58 of the channel part can be inserted in one direction of rotation of the nozzle, but can be rotated by 90 ° to the Fix the nozzle in this position. It will be appreciated that with this arrangement the nozzles are in a desired location can be set along the length of the bath. Furthermore, the nozzles can be connected to the space 66 or a water supply channel communicate from either side of the bath. In order to attach a nozzle to the channel part, therefore

• ·

Ι A hole was made in the side wall 58 in the right place. The nozzle is then fixed with the help of an adhesive to guarantee a watertight seal. on in this way the pump outlet can be connected to the nozzles in a manner which is easy in this area is to be carried out.

The slope of the channel portion 54 downwards towards the sewer outlet is such that after the bath has been emptied is, the channel part 54 is always empty via the hole 86. Nevertheless, the positioning of the individual nozzles does not have to be be particularly accurate, as certain differences in height are taken up by the vertical pipe sections 52 can. The vertical sections 52 may include short flexible pieces, if necessary, to facilitate installation continue to support.

The main resistance in the flow of water to the nozzles is in the vertical pipe sections or conduits 52 and not in the channel part 54, which has a conveying or collecting line function creates. Since these sections are all the same regardless of the distance along the bath from the pump for the different nozzles, the flow through the nozzles is essentially the same and with greater difficulty due to bumps in the flow drain are at least greatly reduced or eliminated. Through a T-piece junction in the supply to each nozzle on the common feed pipe, since the nozzles are not connected in cascade as before However, it is possible to provide limiters in the feed to the individual nozzles, which also make it easier make to equalize the water flows to the nozzles.

Since both the inlet to the pump and the outlet from the pump run under the bath, one results simplified construction. The system is still completely self-draining; the inlet pipe to the pump can of course, empty directly into chamber 84 during the

Pump outlet, which part through the space around 66 into the channel 54 is formed, emptied through the small hole 86. The slope of the lower surface of the section of the duct part towards its center together with the slight slope along its length from the pump to the waste water outlet ensure that the interior of space 66 is properly drained. This is a small contribution to water from the pump outlet redirecting dix'ekt back into the inlet through hole 86; however, it is very small because the diameter of the Hole 86 may only be on the order of 3mm or so. The side walls 58 have a small angle to the vertical, so that the ear portions 82 which lead up to the individual nozzles 32 at none Must run exactly horizontally, which, in order to allow a slight lowering, would lead to that a small amount of stale water remains when the belt is emptied.

Also the length of the pipe work under the bath means that the bathtub feet, which are often close to the sides lying in the bathtub so that they cannot disturb.

It will be recognized that the embodiment of Figures 2-8 can be modified in many ways. For example an air blowing system with a venturi system can be included. The shape of the extrusion which forms the channel part 54 can be very different from the one shown. In a simple case it can consist of two tubes that are arranged one above the other in the form of an 8-shaped section, or three tubes can be provided next to one another the middle one being connected between chamber 84 and the pump inlet, and the two outer ones Pipes are connected to the pump outlet. Another possible shape is as shown in Fig. 9, which is a view similar to FIG. 6 of the sewer outlet end portion 72 in a modified system. In this System is the pump inlet line 60 'in the middle of the

Channel part 54 * arranged and runs sufficiently deep in the part / so that two transverse holes 86 'can drain the interior of the pipeline into the pump inlet channel 64. These Lpcher 86 'replace the hole 86 in the end face of the end- partly in the arrangement of FIGS. 2 to 8. At the pump-side end of the pipeline 54 there is of course a corresponding shaped end part required.

With this channel section, the central tube can be more convenient may be a length of straight cylindrical tube loosely retained in the duct sub-housing. The pump end part can also be as shown in FIG. 11, which the channel part housing 200 and a loosely seated Shows central tube 202 received in pump end portion 204. The central tube 202 is with a Butt tube section 206 glued, the other end 208 is connected to the pipe inlet, and the return or

Fig. 2 records. From the sides of the channel section, secondary feeder pipes 52 lead to the individual nozzles 12, which are Venturi nozzles. Air for the nozzles 12 arrives in the system via a controller 230 and is fed via a large-dimensioned pipe 228 to two distributors 232 on each side of the bath. Thin, flexible pipes 234 lead from the distributor 232 to the individual nozzles 12.

In the embodiment in Figs. 2 to 8 is in the waste water outlet end portion 72 housed the bathtub locking mechanism, which opened the bottom opening 96 in the chamber

84 closes so that when the bath is used, the 5

Chamber (at 25) with both the interior of the bathtub and with the pump inlet tube 60 in communication. A Conventional pull-up drain plug could be used at outlet 96 of chamber 84 and through a Rope (e.g. a construction hoist) can be controlled from a convenient location. The rope operates a toggle lever that is mounted outside the unit 72 and has an arm that passes tightly through the side of the unit 72 to to move the locking member vertically between its open and closed positions. Preferably, however a locking system as shown in FIG. 10 is used is.

Fig. 10 illustrates a waste water outlet unit 40 which is set under the bath waste water opening 36 and a housing 102 has. The unit 40 creates a chamber 104 which communicates with the channel 64 of the conduit 54, so that the suction inlet to the pump withdraws from chamber 104. A closable waste water outlet

IGS is provided in the bottom of the housing 1Ö2. 25th

When the bath is in use, the drain outlet 108 is closed in the manner described below. When the bathroom is filled, the chamber 104 is filled. If the pump 16 is now started by actuating the switch unit 146 is water from the bath via the bath waste water opening 36 into the chamber 104 thus via the suction inlet port 64 sucked to the pump 16. From here it is then pressed outwards through the nozzles 32.

Consequently, water is pumped without a special Inlet in the side wall of the bathtub is necessary,

-9-

and also delivered at a height which is a maximum

Adaptability in the vertical positioning of the |

Pumps 16 and the nozzles 32 allows. *

After use, the pump 16 is switched off. To that To empty the bath, the waste water outlet 108 is opened and the water exits the bathtub through the waste water opening 36 and the chamber 104 in the unit 40. Water can also be withdrawn from the pump via the conduit 54 and the hole 86 will. As a result, there is no risk of stale water remaining in the pipeline.

The unit 40 fits into the sewer opening 36, in the bathtub 30 and has a neck 130 with a flange 132,

! 5 which sits on the inside of the bathtub, whereby the Extension 130 passes through opening 36. The housing 102 is screwed onto the boss 130, and a sealing washer is located between the top surface of the housing 102 and the bathtub 30.

In the approach 130 an insert 136 is housed, which a disk 138 provided with an opening, which is screwed into the extension 130, and an extension 140 with has a central bore 142. The bore 142 receives a shaft 144, which in the bore within the following limits described is displaceable and rotatable. The lower end of the shaft 144 carries a plug or Closure 146 to close outlet 138 from chamber 104. This closure has a sealing ring 148. That The upper end of the shaft is externally threaded to a dome-shaped cover plate 150 with a decorative Appearance, and is preferably provided with an opening to facilitate the flow of water.

A spring 152 presses on the one hand against the top of the disk 138 and on the other hand against the underside of the cover plate 150 or a flange at the top of the shaft

- 10 -

-ΙΟΙ 144. This biases the shaft 144 upwards. Of the The extent of their movement in this direction is limited by a cross pin 154 in the central part of the shaft, which presses against the lower edge of the extension 140 provided with an incision. The extension has two diametrically opposed Slots 156, which allow the shaft in a rotational movement of the shaft 144 in a highest Position is moved. This is the one shown in FIG Position and it is the position in which the sewage outlet 108 is open. If the cover plate 150 is now against the spring 152 is pressed, the bolt 154 can be moved freely through the slots 156, and the cover plate 150 can be rotated, thereby rotating the shaft 144. At an angle of 90 ° to the position of the slots 156 carries the lower surface of the extension 140 has a transverse recess 158 which creates a locking position. if the bolt 154 is recessed in the recess 158, the bather recognizes that the waste water outlet 138 through the closure 146 is closed. Consequently, the bolt 154 cooperates with the lower edge of the extension 140, whereby S.

a bayonet-like effect results.

When the shaft 144 is in its lower position, the closure 156 is pressed by a spring 160 against the sewage outlet 108 pressed. This can be a pretty weak spring as it closes due to the water pressure above of the lock is supported. The shutter 146 is freely supported on the shaft and is secured by a pin 162 withheld. This free but spring-loaded mounting of the stop means that there are slight differences in the Thickness of the bathtub 30 can easily be compensated for without the sealing effect being lost. It can From time to time it may prove necessary to replace the sealing ring 148 on the closure 146. This is going on achieved in the following way. The cover plate is moved to the valve opening position. Furthermore, a forced rotation to remove the cover plate from the shaft 144

1 screwed so that the disc 138 of the insert 136 is exposed. The insert 136 can now be removed from the attachment 130 are unscrewed, whereby the shaft 144 and the attached lock 146 is taken. The sealing

5 ring 148 can now be easily replaced and the unit reassembled. The whole replacement process can be carried out without access from the underside of the bathtub.

10 The cover plate 150 can easily be operated by hand or even with the foot of the bather, and has for this purpose a corresponding diameter of at least 5 cm and preferably of about 8.5 cm. To the Aulaß close, the cover plate and in one direction

The pump 222 can now water from the bath under the edge of the flange 264 over the filter 258 and consequently at the outlet 252 of the part 250. The filter section has a molded part with a Number of spokes to hold back large objects so they don't accidentally reach the pump without that they are met with a significant resistance on the way to the pump. When the middle part 266 of the cover is released, the outlet is open and the water flows away. The filter part 258 can also be bypassed when water flows under the raised central portion 266 into the hole in the center of the outer portion 262 can.

The filter part 258 is preferably seated in the socket 254, so that the arrangement of the cover 260, the filter part 258, the shaft 270 and the closing part 276 for a check, Cleaning and maintenance can be taken out of the bathroom. In the example shown are the exterior of the filter part and the interior of the socket are each knurled, so that a strong, straight, upward Pulling on the cover removes the internal structure, which is normally frictionally engaged in is sufficiently restrained.
