Definitions

the invention relates to an overflow device in particular for a washing area in the sanitary area according to the preamble of claim 1.
the device for collecting a liquid which is designed, for example, in the form of a washstand, has an upper opening through which the maximum fill level is determined. As soon as the liquid accumulated in the collecting device, such as water, exceeds the maximum fill level, further water flowing into the collecting device flows into a drain via the upper opening, so that the collecting device ultimately does not overflow and thus, for example, a bathroom is not under water can put.
So-called hidden overflows in which long tubes are used, are also known in sanitary practice. These are relatively dirty. The heat builds up in the tubes, thereby creating an ideal breeding climate for harmful germs. Also, the water accumulated in the tubes usually has a direct flow connection to the water in the wash basin, so that fresh water in the wash basin can also come into contact with the germs in the tube system. The water then has direct contact with the aforementioned biofilm in the event of a covered overflow. Washing infants or old people with water from such washbasins can be correspondingly problematic.
An overflow device of the type mentioned is also from the EP 2 918 739 A1 known.
This device has a pressure sensor that detects the height of the water level, an electronic measuring and control device to which the measurement signals of the pressure sensor are transmitted, and an actuator for opening and / or closing a floor drain valve, the actuator being separated from the measuring and control device in Dependence of the water level detected by the pressure sensor is controlled.
the invention has for its object to provide an overflow device that is simpler and less problematic to handle.
the overflow device which can be used in particular for a washing area in the sanitary area, has a device for collecting a liquid and a device by means of which an overflow of the collecting device is prevented, the device for preventing overflow of the collecting device having a valve which consists of a an outflow of the liquid from the collection device enabling release position can be moved into a blocking position preventing the outflow and vice versa, and the valve moves automatically from its blocking position into its release position when the maximum filling level of the collection device is exceeded.
an “automatic process” is understood to mean a process of the valve without further aids, such as pressure sensors, electrical or electronic measuring and control devices, actuators or also mechanical aids, such as springs.
valve alone has the function of an overflow protection in the sense of a double function and other elements, such as overflow openings in the collecting device, connecting lines from the overflow opening to the drain, hidden overflows or the aforementioned electrical, electronic or mechanical aids, are complete can be omitted.
the overflow device according to the invention is thus constructed on the one hand simply and safely, on the other hand it can be handled very easily with regard to the germs which are partially present in the further elements. Since these other elements are omitted, no dirt residues, biofilms or germs can form in them.
the valve can be moved from its blocking position into its release position by forces acting on it from the hydrostatic pressure of the liquid column, buoyancy and weight.
the level of the hydrostatic pressure in relation to the buoyancy counteracting the former is therefore the trigger for transferring the valve from its blocking position into its release position or for leaving it in its blocking position. It follows from this that the liquid in the collecting device monitors itself to a certain extent. If the hydrostatic pressure rises above a threshold value, this presses the valve against the lift from its blocking position in its release position. As long as the hydrostatic pressure is below the threshold value, the valve remains in its blocking position.
the valve has a round, oval, elliptical or a rectangular, in particular square, cross-sectional area, the valve having an upper sealing section, which preferably seals the collecting device in a linear manner in the blocking position.
the collecting device has a container, preferably a siphon, filled with liquid and at least partially accommodating the valve, the container, preferably a siphon, preferably being arranged directly below the collecting device.
the siphon can also have the function of accommodating the valve.
Siphons designed in the usual way are arranged significantly lower than the siphon according to the invention.
short paths can be implemented for the liquid flowing out of the collecting device, so that the overflow device according to the invention can ultimately also be produced very inexpensively.
the siphon according to the invention thus also blocks significantly less drawer space below the washing area, such as below the washstand, so that expensive siphon cutouts can be avoided or eliminated in such drawers.
valve in the container filled with liquid preferably a siphon
liquid preferably a siphon
buoyant forces acting on the valve It follows that the valve is at least partially immersed in the liquid in the container, preferably a siphon, and counteracted by gravity, e.g. upwards, is pressed into its locked position or is acted upon.
an adjustment device by means of which the valve arranged in the container, preferably a siphon, can be moved into its release position. This ensures that the valve is replaced by a Actuation of the adjusting device can be moved with the force of gravity, ie downwards, so that the aforementioned buoyancy forces can no longer hold the valve in its blocking position.
the liquid such as water
the collecting device such as the washstand. The water cannot build up in the collecting device.
the valve automatically moves from its release position back into its blocking position when the level of the collecting device falls below the maximum filling level and the adjusting device does not act or is not actuated.
the overflow device according to the invention can thus also be used to maintain or regulate a desired fill level in a collecting device into which liquid continuously flows.
the invention relates generally to an overflow device.
the invention relates to a washing area in the sanitary area, such as a washstand, also called a sink, or a bathtub.
a washstand also called a sink
a bathtub In the 1 to 3 are a cut symbolize hatching for simplicity and better clarity omitted.
FIGS 1 to 3 An overflow device 1 for a washing area 2 in the sanitary area is shown schematically in a partial vertical section in various working positions in FIGS 1 to 3 shown.
Fig. 1 A first working position is shown, in which the overflow device 1 allows liquid, such as water, to flow out of the washstand 2.
the overflow device 1 has a device 3 for collecting the liquid 5 flowing, for example, from a tap 4, such as a mixer tap, also called a mixer tap.
a tap 4 such as a mixer tap, also called a mixer tap.
the device 3 for collecting the liquid is briefly called a collecting device 3.
the collecting device 3 is, as mentioned above, for example a basin or a tub.
the overflow device 1 has a device 6 by means of which the collecting device 3 is prevented from overflowing.
the device 6 for preventing the overflow of the collecting device 3 has a valve 7. This valve can be moved from a release position which enables the liquid 5 to flow away from the collecting device 3 into a blocking position preventing the flow and vice versa.
the release position of the valve 7 is for example in the Fig. 1 and 3rd , the blocking position of the valve 7 in Fig. 2 shown.
the washing area 2 with its collecting device 3 is fastened to a wall 10 in a manner not shown in detail.
the collecting device 3 preferably has at its lowest point a drain opening 11 which is connected to a drain (not shown in more detail) via a siphon 12 and a pipe 13 leading to the wall 10.
Fig. 1 the overflow device 1 is shown in its first working position, which allows liquid to flow out of the collecting device 3.
the liquid 5 flowing into the collecting device 3 via the tap 4 can flow along the arrows A through the drain opening 11, the siphon 12 and pipeline 13 to the drain, not shown in any more detail.
the liquid 5 is therefore not accumulated in the collecting device 3 in this working position.
This working position of the overflow device 1 is used, for example, for washing hands.
the valve 7 moves when a maximum fill level 14 is exceeded (see Fig. 2 and 3rd ) of the collecting device 3 automatically from its blocking position into its release position, so that excess liquid can flow out of the collecting device.
the invention is based on the general idea that the valve 7 can be moved from its blocking position into its release position and vice versa solely by the hydrostatic pressure of the liquid column 15 above the valve 7, without additional aids for switching the valve being required. This applies in particular when the hydrostatic pressure of the liquid column 15 located above the valve 7 exceeds a certain threshold value, which is also determined by the lift of the valve. At this point in time, the valve opens so that liquid located above the maximum fill level 15 flows out of the collecting device 3.
the valve 7 has a round, oval, elliptical or a rectangular, in particular square, cross-sectional area 16.
the valve 7 also has an upper sealing section 17 which, in the blocking position of the valve 7, seals the collecting device 3 linearly on an annular sealing lip 20 seated in the drain opening 11, as shown in FIG Fig. 2 is indicated.
the collecting device 3 In the in Fig. 2 shown second working position of the overflow device 1, the collecting device 3 is thus sealed, so that liquid 5 flowing into the collecting device 3 collects in the collecting device 3 and builds up in this in the direction of the arrow B pointing upward.
a container filled with liquid and at least partially accommodating the valve 7, preferably the siphon 12, is arranged directly below the collecting device 3.
the container, preferably siphon 12, is thus fluidically seated connected immediately below the drain opening 11 of the collecting device 3.
the siphon 12, as is customary and in the 1 to 3 indicated is filled with the liquid 5.
the container filled with liquid and at least partially accommodating the valve is not necessarily designed as a siphon.
the functions "overflow” and "siphon" can also be separated, for example for reasons of space, according to an embodiment that is not shown in detail.
the siphon can also be arranged leaving a distance below the collecting device, that is, it does not necessarily have to be arranged directly below the collecting device.
Fig. 2 further clarifies that the valve 7 in the container filled with liquid 5, namely the siphon 12, is preloaded into its blocking position by buoyant forces acting on the valve 7.
the valve therefore also functions as a float.
the entirety of the forces acting on the valve 7, here in particular the hydrostatic pressure of the liquid column, buoyancy and weight forces, have the effect that the valve 7, provided that the buoyancy exceeds the pressure of the liquid column and the weight force, seals the collecting device 3 in it Locked position.
This blocking position of the valve 7 thus corresponds to the second working position of the overflow device 1; this remains maintained until the fill level accumulated in the collecting device 3 has reached and exceeded the maximum fill level 14.
an adjusting device 21 is provided, by means of which the valve 7 arranged in the container, preferably siphon 12, can be moved into its release position.
the adjusting device 21 thus causes the valve 7 to be moved from its blocking position into its release position. Since the valve, as mentioned above, is preloaded into its blocking position, the adjusting device 21 effects an adjustment of the valve seated in the container, preferably siphon 12, against its buoyancy forces, so that the valve is in its lower release position and no longer in its preloaded position upper locked position.
the adjusting device 21 is according to the in the 1 to 3
a U-shaped magnet 22 for example a permanent magnet, which, if it is close enough to the magnetic valve 7, pulls it downward against buoyancy forces acting on the valve.
Fig. 1 is the adjusting device 21 in its actuated, ie active position, while the adjusting device 21 is in the Fig. 2 and 3rd is in its non-actuated, ie passive position.
the adjustment device 21 is in the Fig. 2 and 3rd moved away from the siphon 12 and thus from the valve 7 while they are in accordance with Fig. 1 is located directly on the siphon 12 and can thus act on the valve 7.
the valve 7 automatically moves from its release position into its blocking position when the maximum fill level 14 of the collecting device 3 is undershot and the passive adjusting device 21 does not act.
the overflow device 1 according to the invention can also be used as a device for regulating the fill level, by means of which only excess liquid is drained off (see arrow C in Fig. 3 ) and almost a constant fill level is established in the collecting device. In the latter case of a liquid flowing into a pent-up collecting device, the valve 7 oscillates in the direction of the double arrow D automatically and therefore automatically between its release and blocking position.
adjustment device can also be designed in some other way, in particular mechanically, for example via a linkage or a cable pull.
the valve opens as soon as the weight of the liquid column or the hydrostatic pressure of the liquid column together with the weight of the valve is greater than the buoyancy of the valve designed as a floating body in the container, preferably a siphon. Conversely, if the buoyancy is greater than the weight of the liquid column and the weight of the valve, the latter closes. The resulting force acting on the valve thus causes the valve to be transferred either to its blocking position or to its release position
