Description

DETAILED DESCRIPTION OF THE INVENTION A sanitary device with an easily accessible chamber equipped with a mechanism that combines the opening and closing of an outlet, an overflow, an air intake system and a water seal in the underlying container.

DESCRIPTION The present invention is directed to a washbasin, bidet, bathtub or shower tub,
It relates to sanitary devices such as kitchen or laundry sinks, toilet bowls, which have a main basin and an adjacent chamber separated from this basin by a wall, and which communicates with the chamber on the side of the main basin. There is also an outlet for the chamber and an outlet for the chamber.
In addition, the sanitary equipment is equipped with an opening and closing device attached to the chamber and operated from outside the chamber,
The device is equipped with an upright pipe between a closed position that prevents direct flow of liquid from the outlet of the main basin to the outlet of the chamber and an open position that allows direct flow of liquid. You can move with.

This type of sanitary device can be attractive because it does not have a drain on the bottom, especially a closure that closes the drain, and allows the designer more freedom in designing. At the same time, it is also possible to prevent the drain outlet from being clogged immediately.

A sanitary device of this kind is disclosed in British Patent 363,601.

A hollow rotary sleeve valve is installed in a chamber in the shape of a drainage duct provided in the thick part of the back wall of the main basin.

In the open position this valve ensures direct communication between the outlet on the back of the main basin and the outlet on the bottom of the chamber.

Rotating the sleeve valve prevents this communication.

German patent 140,899 also discloses a sanitary device of the type mentioned above.

The pipe of the opening and closing device can move up and down. In the lowered position it closes the outlet at the bottom of the chamber.

The liquid can only be drained through an opening at the top of the pipe, this opening acting as an overflow opening. In the raised position, liquid can be drained from the chamber through an opening at the lower end of the pipe. Since the chamber is watertightly closed except at the outlet, the water discharged through the opening at the lower end of the pipe draws in the air in the chamber so that some of the water flows through the overflow opening at the upper end of the pipe.

The problem with both of these known devices is that the chamber is difficult to clean.

Even if you could remove the switchgear from the device,
Cannot easily reach the bottom of the chamber.

Even if the water seal is installed directly under the chamber, the water seal cannot actually be reached due to cleaning through the chamber.

The water seal must be removed from the outside of the sanitary device, which is not always possible or easy.

The object of the present invention is to eliminate this drawback, and the chamber fitted with the switching device can be easily cleaned,
And to provide a sanitary device of the type mentioned above, in which the water seal forming the container mounted under the chamber can be easily cleaned.

For this purpose, at least part of the wall separating the chamber and the main basin is removable.

That part of the wall is either completely removable, for example by sliding, or it can be swung relative to the other parts of the wall.

In a particular embodiment of the invention, the sanitary device comprises a container below the chamber and connected to the chamber through an outlet at the bottom of the chamber, the movable pipe of the opening and closing device extending through the outlet into the container. , And forms a water seal with the container.

In this form of embodiment, the water seal is in a very high position and is easily hidden by the sanitary device itself or by, for example, a footpiece.

In the case of a bathtub, it can be placed very low on the floor.

This type of embodiment is particularly useful in combination with the features described above. This is because the water seal can be easily reached for cleaning after removing the movable part of the wall separating the chamber and the main basin. The container is preferably an integral part of the sanitary device.

A main basin, an adjacent chamber in communication with this main basin via an outlet and provided on itself with an outlet closed by an opening and closing device, and attached below this chamber, forming an integral part of the sanitary device And a sanitary device comprising a container forming a water seal with the lower part of the opening and closing device is shown in German patent application 1,609,108.

However, in this known sanitary device, the opening and closing device does not have a movable pipe that prevents or allows a direct connection between the outlet at the bottom of the chamber and the outlet at the basin.

Said opening and closing device comprises a tube fixed to the chamber and provided with openings, which openings can be closed by valve elements movably mounted on the pipe.

This switchgear therefore has a rather complicated structure.

In an advantageous embodiment of the invention, the sanitary device is mounted in a chamber and is connected to a container to allow air above the liquid into the container at low pressure or the outlet of the container. It is equipped with an air intake device that acts to enter.

In this form of embodiment, the drain system connecting the sanitary device can be small and the liquid movement is good.

In a preferred embodiment of the invention, the movable pipe of the opening / closing device is provided in a position lying above the bottom of the chamber in its closed position, the overflow opening communicating with the basin outlet through the chamber. There is.

The normal overflow opening in the side wall of the sanitary device can be omitted.

When the liquid level of the main basin exceeds a predetermined value, the liquid of the same level in the chamber is discharged through the overflow opening in the upper portion of the movable pipe.

Other features and advantages of the invention will be apparent from the following description of several embodiments of the sanitary device of the invention. These descriptions are merely examples and do not limit the present invention. The reference numerals are those used in the attached figures.

FIG. 1 shows the working principle of a washbasin or bidet.

FIG. 2 shows an example of a chamber with a removable front, which combines a fixed pipe forming a water seal in the lower water trap with an open / close pipe.

FIG. 3 is a view similar to FIG. 2, but with the open / close pipe extended downward to form a seal within the trap.

FIG. 4 shows the present invention applied to a bathtub.

FIG. 5 shows the invention applied to a sink.

FIG. 6 is the same as that of FIG. 5, but without the overflow.

FIG. 7 shows an air intake valve associated with a movable opening / closing pipe.

FIG. 8 shows another example of the opening / closing mechanism.

With a wall of suitable shape 4 in a chamber 1 formed by a removable front 3 with one or more holes or recesses 2 for adjacent devices 11 and a hole 5 connecting to a water lock 6 Has a bottom and is from outside the device 8
A pipe 7 that can be operated with is arranged, the upper end and the lower end of this pipe are open, the lower end fits tightly into the outlet hole 5 and tightens, the open upper end 12 overflows, i.e. the water level rises in the sanitary equipment, Therefore, even in the chamber 1, when the water rises to the height of the open end 12, the water is automatically piped.
It is intended for pouring into and into the release system without obstruction. When the pipe 7 is raised (changed) from its clamped position by means of the actuating part 8, the water will pass through hole 5 or the opening.
Drain directly through 15 and into water lock 6.

As shown in FIG. 1, when the lower end of the front 3 is the recess 2, the recess 2 serves as a hole formed between the front 3 and the bottom of the adjacent device 11 and serves as an outlet from the adjacent device 11 to the chamber 1. Constitute.

As shown in FIG. 3, a water lock is placed inside the container 14.
Extending the pipe downwards to form 13 has another advantage.

In the closed position the hole 15 is submerged in the seat 16 and raising the pipes 7, 13 causes the hole to leave the seat. This allows the container 14 to be made as an integral part of the device, or in a very simple manner, and in addition to have a recess for inspection and maintenance by removing the rear mechanism 7,13 without the front 3. Easy access to exits.

Figures 5 and 6 show how the invention can be applied to a sink, in which case water can flow even if the bottom of the basin is clogged with food residues. In this case, the removable front is in the shape of a scoop and covers the bottom. In this way the skin and the rest of the food can be easily processed.

Very important in conventional installations, the pipe behind the sanitary device is large enough to ensure good operation of the water trap, which keeps the dirty air of the exhaust system from entering the living space of the house. It has a diameter. If the pipe diameter is too small, the effluent water will fill the entire cross section of the pipe, creating a pumping effect that affects the trap when the water stops flowing.

In order to eliminate this pump effect, for example, British Patent 2,014,697
Place the air intake valve (Fig. 7, 20) described in 1 above in the chamber 1 above the overflow level. This valve connects to the top of the container 14 by another channel 21 to bypass the opening and closing mechanism and the water seal. This channel 21 is likewise independent as an integral part of the movable pipe 7. As such, it takes in air when underpressure or pumping effects occur and balances the pressure so that the waterlock is not affected.

Thus, even if the pipe may be completely filled, the diameter of the drainage system may be reduced and the rate of water exiting may be increased. A further advantage is that sedimentation and clogging of the exhaust system is prevented.

The present invention is not limited to the field of hygiene, but has other areas of application to other types of tanks and containers in corporate kitchens, enterprises and the like.

The application of the present invention to a new configuration of a sanitary device not only aims to make the sanitary device attractive by eliminating the usual unsightly exit and overflow holes, but also improves its function. And it's actually expensive,
Simplifies opening and closing devices and overflows, which are also complicated, and significantly reduce the number of screws and fittings,
It can be implemented with the aim of simplifying the device and making it economical. Finally, the present invention contributes to the full utilization of cupboards incorporating washbasins and sinks. This is because on the one hand the usual bulky water trap becomes smaller and on the other hand the water trap is arranged behind the sanitary device.
