Definitions
- the invention relates to a flushing device according to the preamble of claim 1.
- a device of this type is known from EP-A-0 352 712.
- this flushing device two water feeds to a toilet bowl are provided.
- One water supply leads to the bowl rim and the other supply leads to an odor trap arranged in the lower area of the bowl.
- the bowl is cleaned with a rinse water stream and the water present in the odor trap is set in motion with another rinse water stream.
- the one for an effective rinse The minimum amount of water required is much smaller in such a flushing device than in a flushing device with only one flushing stream for cleaning the toilet bowl.
- the flushing device is designed as a so-called pressure flushing device.
- a comparatively complex control device is required to control the two rinsing water flows.
- FIG. 7 shows an embodiment in which the water used for rinsing is stored in a rinsing water tank.
- a branch line which leads to the odor trap of the toilet bowl, is connected to an outlet line of the rinsing water container.
- an elaborate control device and valves and pressure display devices are required in the lines, with which the two flushing water flows are controlled.
- the invention has for its object to provide a flushing device of the type mentioned which, in comparison to pressure flushing devices, loads the line network considerably less, operates with less noise and which achieves the required flushing action with a minimal amount of flushing water.
- the object is achieved in a generic flushing device according to the characterizing part of patent claim 1.
- the flushing device In the flushing device according to the invention, a portion of the flushing water in the flushing water container is pressurized during the flushing process. This pressurized water is discharged to the outlet, which leads to the odor trap located in the lower area of the toilet bowl.
- the rinsing device it is therefore possible to accelerate the water in the odor trap in such a way that this odor trap is better rinsed out.
- the water of the odor trap is set in motion for a short time and a more effective emptying of the odor trap is achieved. With the gravity-loaded flushing stream, only the toilet bowl then has to be cleaned and the partially emptied odor trap has to be refilled.
- the flushing device according to the invention In the case of the flushing device according to the invention, an unpressurized and a pressurized flushing water quantity is thus delivered during flushing. Compared to a conventional flushing box, a smaller amount of flushing water is thus required for the same flushing effect. Compared to pressure flushing devices, the flushing device according to the invention places a significantly lower load on the line network and in this respect corresponds to a conventional flushing cistern.
- the means with which a flushing water quantity can be pressurized have a cylinder-piston unit with a piston, which at a rinse with the water of the water supply line can be acted upon.
- the piston is displaced by the pressure of the water from the supply line and a certain amount of flushing water present in the unit is pressurized.
- a cylinder piston unit can be housed in a cistern. Such a cistern can then be operated as usual with a button.
- a particularly effective flushing is achieved if, by means of a control device, the water in the cylinder piston unit is released under pressure with a delay. It can thereby be achieved that the rinsing flow, which is subject to gravity, and the rinsing flow, which is pressurized, act essentially simultaneously in the siphon or odor trap.
- this control device can be implemented particularly simply by a float which actuates a servo-controlled inlet valve.
- the invention also relates to a toilet system with a flushing device according to claim 16.
- the flushing action is particularly effective if, according to a further development of the invention, the nozzle is arranged inclined with respect to the horizontal in such a way that the flushing water emitted by the nozzle has a downstream movement towards the water in the arch of the odor trap exercises.
- FIG. 1 schematically shows a section through a toilet system according to the invention
- FIG. 3 is a partially sectioned top view of the washing device according to FIG. 2,
- Fig. 4 is a control diagram of the flushing device, which is in the idle state.
- FIG. 5 shows the control diagram according to FIG. 4, but during a rinsing process.
- Fig. 1 shows a flushing device 1, which is connected via a pipe bend 12 to a toilet bowl 45.
- a drain valve 13 is accommodated in a box 8 of the flushing device 1 and can be actuated with an actuating device 17 to open an opening 55 in the bottom of the box 8.
- Actuator 17 may be a button or push button or other triggering device his.
- box 8 there is also an inlet valve 4 which is connected to a water supply line 2. When the inlet valve 4 is open, the box 8 is filled with rinsing water 50 up to a predetermined level.
- part of the rinsing water 50 flows through the pipe bend 12 into a channel 51 of a rim 47 and flows downward in the direction of the arrows 53 on the inside of a basin 56 into a U-shaped bend 46 which forms an odor trap in relation to an outlet 52.
- Another much smaller part of the rinsing water 50 is pressurized with means described in more detail below in the box 8 and passes via a line 9 to a nozzle 11 which has a passage 57 into the interior of the arc 46.
- This nozzle 11 is directed such that, as shown in FIG. 1, water flowing through the nozzle 11 flows in the direction of the arrow 58 into the water 70 present in the arc 46.
- the direction of the arrow 58 is at the same time the flow direction of the water 70 during the rinsing process and thus when the odor trap is emptied.
- a suitable angle of inclination ⁇ can be seen in FIG. 1. This angle ⁇ is, for example, approximately 10 ° and is preferably less than 45 °.
- the rinsing stream flowing through the nozzle 11 has, for example, a small excess pressure, while the rinsing water flowing into the bowl 56 through the channel 51 is only subjected to gravity.
- the amount of rinsing water flowing in during a rinsing through the nozzle 11 is preferably considerably smaller than that rinsed off through the channel 51.
- the flushing water flowing into the water under overpressure in the direction of the arrow 58 moves the water 70 in the direction of the arrow 58 and has the effect that the bow 46 is better rinsed out.
- Excrements in the arch 46 are entrained and conveyed to the outlet 52.
- the box 8 can be a conventional box with an outlet connection 59 arranged in the bottom and a cover, not shown here.
- the drain valve 13 can be a known float valve in which a valve tube 16 is guided in a float housing 60.
- the valve tube 16 can be raised with a button 17 which can be pivoted about a bearing 18.
- a valve plate 15 opens the opening 14, whereupon rinsing water 50 located in the box 8 flows through the pipe bend 12 into the channel 51.
- the drain valve 13 closes automatically in a known manner.
- a cylinder piston unit 6 which essentially consists of two housing parts 33 and 40 and a double piston 61.
- the unit 6 is connected to the inlet valve 4, which is connected to the water supply line 2 at a connection piece 62.
- the inlet valve 4 is a servo-controlled diaphragm valve. 2 closes an opening 28 in a passage 29 with a membrane 27.
- a passage opening 63 in the membrane 27 connects a chamber 29a of the connecting piece 62 to a chamber 26 of a frame 23.
- the chamber 26 there is Water which is connected to the water of the supply line 2 through the opening 63 and has the same pressure. Since the diaphragm 27 now has a larger area in relation to the chamber 26 than in relation to the chamber 29a, the latter is pressed against the valve seat of the opening 28 towards the top.
- the chamber 26 has a passage 25 which, in the arrangement shown, is closed by a valve rod 24 which is displaceably mounted on the frame 23.
- a float 21 is attached, which is located in a float housing 20.
- the float 21 is largely below the water level marked by the letter A.
- a valve 22 is arranged in the bottom of the float housing 20, which is open when the flushing tank is full and thus connects the interior of the float housing 20 with its outside.
- the housing 20 is filled with water and gives the float 21 a drive which presses the rod 24 against a valve seat of the through opening 25.
- valve tube 16 If the valve tube 16 is now raised during a flushing with the button 17, the water level in the cistern 8 and at the same time the level of the water in the float tank 20 decrease. The buoyancy of the float 21 thus becomes progressively smaller until, finally, this is due to its own weight downwards falls and thus the passage opening 25 will be released. Through the passage 25, water can escape from the chamber 26 to the outside, whereby the pressure in the chamber 26 is immediately reduced. Due to the now higher water pressure in the chamber 29a, the membrane 27 is moved downward and lifted off the opening 28. The passage from chamber 29a to chamber 29b is thus open.
- water can now pass through the passage 29 into a chamber 5, which is sealed off from an interior 64 of the housing part 33 with a piston 30 and a circumferential lip seal 31.
- a quantity regulator 3 arranged in front of the membrane 27 limits the quantity of water flowing into the chamber 5 per unit time.
- the quantity regulator 3 is preferably set such that the water flowing into the chamber 5 has a maximum flow pressure.
- the piston 30 is fixedly connected via a web 32 to a piston 37 arranged below.
- This piston 37 has a check valve 36 which is open in the position shown and connects the interior 64 to an interior 65 of the housing part 40.
- Valve 36 seals piston 37 with a circumferential lip seal 38 from interior 65 to space 64.
- the two pistons 30 and 37 thus form a double piston 61.
- the space 65 leads via a passage 41 to a check valve 7 which has a closure body 42 which can be lifted off a valve seat 66 against the retroactive force of a compression spring 43.
- the check valve 7 has a connecting piece 44 to which the line 9 leading to the nozzle 11 is connected.
- the lip seal 31 runs over a plurality of through holes 34 in the housing 33.
- the chamber 5 flows through the through Openings 34 water outwards into the cistern and refills it until the water level A is reached.
- a ring 35 attached to the outside of the housing 33, the water flowing out through the holes 34 is directed downward with little noise.
- the chamber 65 is filled with water again by means of a cylinder filling valve (not shown here), the cylinder 37 again being moved into the starting position shown in FIG. 2.
- the control float according to FIG. 4 shows the idle state of the cistern.
- the inlet valve 4 the outlet valve 13 are closed and the cylinder fill valve 69 is opened.
- the pressure in the supply line 2 is, for example, 1 to 10 bar. If the drain valve 13 is now opened for rinsing, water flows into the pipe bend 12 with the usual rinsing line.
- the check valve 22 of the control device 54 is set in such a way that the float 21 only moves down when the water 50 reaches the 2 has reached the water level marked with B. At this water level B, the inlet valve 4 is opened immediately and water is displaced from the chamber 65 into the line 9.
- the time delay caused by the control device 54 is set such that rinsing water is then dispensed through the nozzle 11 when the water flowing into the basin 56 through the channel 51 has reached the arc 46.
- the control scheme according to FIG. 5 corresponds to this state. In this case, the drain valve 13, the inlet valve 4 and the check valve 7 are open. The time period during which water is released through the nozzle 11 is comparatively short.
