Definitions

  • the present invention relates to a toilet flushing module with a flushing cistern for maintaining a flushing volume, from which a flushing line branches off, which connects the flushing cistern to a connection for a toilet bowl, an inlet valve for filling the cistern, which can be connected to a fresh water line, and a waste water pipe that the toilet bowl can be connected to a sewage pipe.
  • Such toilet flushing modules are known. Sometimes fresh water is drained from the fresh water line into the cistern when the cold water in the fresh water line heats up and stands out, for example if the toilet is not flushed for a longer period of time due to use of the toilet (see Fig. DE 10 2004 033 770 A1 ). This type of line flushing, which prevents water from standing in the lines and thus prevents the formation of legionella, is referred to below as a hygiene measure.
  • a hotel guest can be irritated, for example, if there is no other person in the hotel room and a supposed toilet flush is triggered. Even if the hotel guest is informed about the hygiene measures in such a case and expects a flush without using the toilet, this flushing through the toilet bowl, especially at night, represents a noise nuisance. In addition, there is a risk with the hygiene measure that any existing blockages in of the toilet bowl are not detected and the flush then leads to an overflow.
  • the present invention seeks to remedy these problems.
  • the present invention proposes a toilet flushing module with the features of claim 1.
  • This is characterized by a bypass line connected in parallel to the flushing line, via which the cistern can be connected to the waste water line, bypassing the toilet bowl.
  • the hygiene measure can thus be carried out without surprising or irritating a user of the toilet with an unexpected toilet flush.
  • noise pollution, especially at night, and overflowing due to an unnoticed clogging of the toilet bowl are avoided.
  • the inlet valve of the toilet flushing module is preferably a float valve which is mechanically controlled by a float and opens when falls below a certain level and closes when a target level is reached.
  • the target level thus corresponds to a filling height of the cistern.
  • an electronically controlled valve can also be used as the inlet valve, with the filling of the cistern preferably being controlled on the basis of a measurement of the water level.
  • a float can be used for the measurement.
  • a control logic for a hygiene flush can also be integrated into the control of an electronically controlled inlet valve, so that the inlet valve drains water from the fresh water line if the toilet is not used for a longer period of time.
  • the waste water pipe of the toilet flushing module generally forms a waste water connecting piece at one end for connection to the toilet bowl and at the other end a connecting section for connection to the waste water line.
  • time-controlled triggers or triggers controlled by sensors can be used.
  • sensors are known which register the presence of a person when using the toilet.
  • the toilet flushing module according to the invention can be designed for installation in a pre-wall installation, a concealed installation or a surface-mounted installation.
  • the cistern, the flushing line, the connection for the toilet bowl, the waste water pipe and the bypass line are preferably integrated into a pre-wall installation frame.
  • an inlet opening of the bypass line is provided inside the cistern at or above the filling level.
  • the inlet opening of the bypass line is usually oriented parallel to the water surface of the wash volume.
  • the cistern has an outlet opening connected to the flushing line for discharging the flushing volume in the direction of the toilet bowl, an inlet opening provided above the filling level for the fresh water line and an opening for the bypass line, through which the bypass line is passed in a sealed manner.
  • an outlet valve provided for the outlet opening for opening and closing the outlet opening and a float valve as an inlet valve for filling the cistern are arranged in the cistern.
  • a controllable line flush valve for draining water into the cistern and/or the bypass line is provided.
  • the controllable line flushing valve is preferably a solenoid valve and can preferably be controlled by an electronically controlled control device.
  • the outlet valve is coupled to a toilet flush actuator and the outlet opening is usually provided at the bottom of the cistern.
  • the outlet valve usually protrudes with an upper end out of the scavenging volume, i.e. the upper end is provided above the filling level.
  • the outlet valve often has an inner channel through which water is supposed to overflow into the flushing line in the event of a defect in the float valve, while the outlet valve remains in its closed position, in which the flushing volume can flow out into the flushing line, triggered by the usage situation prevented.
  • such an inner channel can be dispensed with because of the bypass line. If the outlet valve has such an inner channel, the inlet opening of the bypass line is to be arranged below the inlet opening of the inner channel.
  • the inlet opening of the bypass line and, if present, the inlet opening of the inner channel of the outlet valve are arranged with a sufficient vertical distance of at least 20 mm to the outlet(s) of the fresh water line in order to comply with the legal requirements for the separation of drinking water and waste water (see DIN EN 1717 /2011-08: "Free drainage over a drainage object").
  • the opening of the cistern for the bypass line is usually provided on the bottom of the cistern next to the outlet opening.
  • the inlet opening of the cistern for the fresh water line is usually provided in the upper area of a side wall above the fill level and above the inlet openings of the bypass line and the inner channel. The fresh water line is routed through the inlet opening. Sealing is not necessary at this point.
  • the inlet opening of the cistern can be provided directly below a cistern cover.
  • the line flushing valve is arranged inside the flushing tank.
  • the fresh water line usually branches into two line paths in the cistern, with one line path communicating with the float valve and the other line path communicating with the line flushing valve.
  • the fresh water line is a line for cold water or hot water.
  • the toilet flushing module is set up in such a way that the water drained through the line flushing valve is introduced into the bypass line without contact with the flushing volume.
  • a line path of the fresh water line (usually the line path in which the line flushing valve is arranged) preferably ends directly above the inlet opening of the bypass line.
  • the line flushing valve is usually located above the inlet opening of the bypass line.
  • the bypass line has a bypass siphon.
  • the toilet flushing module has a flow sensor for detecting a fresh water flow through the fresh water line.
  • the flow sensor is preferably arranged in the cistern.
  • the flow sensor registers at least one fresh water flow caused by flushing the toilet and subsequent refilling of the flushing volume in the cistern.
  • the flow sensor is usually associated with the fresh water line or provided in the fresh water line.
  • the flow sensor is preferably provided in the direction of flow before the fresh water line branches off into two line paths. There it records a fresh water flow for refilling the flushing volume via the inlet valve and a fresh water flow for the hygiene measure via the line flushing valve. It can just as well be provided downstream of the branch in a line path having the inlet valve.
  • the flow sensor is particularly preferably designed to be adapted for detecting a fresh water flow rate.
  • the line flushing valve is usually controlled by a control unit via a control line.
  • the control unit can be arranged inside the cistern, for example in the area of the cistern cover.
  • the control unit can just as well be remote from the toilet, for example in a central building control center.
  • the control unit is adapted to receive measurement signals from the flow sensor.
  • the control unit preferably also receives measurement signals from a temperature sensor that monitors the water temperature of the fresh water in the fresh water line.
  • the flow sensor is preferably integrated into the control concept for hygienic flushing of the fresh water line. This means that if the flow sensor registers regular toilet flushing, no hygiene flushing of the fresh water line via the line flushing valve is required.
  • the control unit triggers a hygiene measure by opening the line flushing valve.
  • a hygienically questionable water temperature measured with the temperature sensor can also result in a hygiene measure.
  • Time-controlled hygiene measures can usually also be programmed into the control unit. Since the control unit specifies the hygiene measures, the measured fresh water flows or quantities can be correctly assigned to the respective situation if the flow sensor is provided before the fresh water line branches into two line paths.
  • the toilet flush module according to the invention can be connected to a fresh water line for cold water and a cold water line flush valve with a fresh water line for Have hot water connectable hot water line flush valve, which are preferably provided within the cistern.
  • the cold water line flush valve is the line flush valve discussed above, which can be connected to the fresh water line for cold water, via which the cistern is filled with the flush volume and which may supply other consumers (e.g. shower or sink) with cold fresh water.
  • the fresh water line for hot water can be a line connected to consumers for hot water (e.g. shower or sink).
  • a second inlet opening, through which the fresh water line for hot water is passed, can be provided on the cistern. Accordingly, both a hot water line and a cold water line preferably open into the cistern.
  • the present invention specifies a toilet with a fresh water connection, a waste water connection to a waste water system, a toilet flushing line path formed between these two connections and a toilet bowl arranged in the flushing line path, which is flushed through when the toilet is flushed.
  • the toilet is characterized by a bypass line parallel to the toilet flushing line path, through which fresh water can be drained into the sewage system without flushing the toilet bowl.
  • the toilet preferably contains the toilet flushing module according to the invention.
  • parallel does not mean an exact geometric alignment here, but rather the fact that the fresh water can get from the fresh water connection to the waste water connection in two different ways, namely through the flushing line path or through the bypass line.
  • An inlet opening of the bypass line is preferably arranged in a cistern of the toilet.
  • the inlet opening is generally provided at or above the level of the cistern.
  • the flushing line path is usually formed in sections by a flushing line which communicates with an outlet opening of the flushing tank and connects the flushing tank to the toilet bowl.
  • the bypass line is preferably passed through an opening in the cistern, preferably at the bottom of the cistern, in a sealing manner.
  • the outlet opening of the cistern is usually also provided at the bottom of the cistern. Therefore, the flushing line and the bypass line usually run next to each other and parallel at least in sections.
  • the toilet preferably has a line flush valve which is arranged above the inlet opening of the bypass line in the cistern and can be controlled by a control unit and which is connected to a fresh water line.
  • the toilet also preferably has a flow sensor for detecting a fresh water flow introduced into the toilet through the fresh water connection.
  • the bypass line is preferably connected to a drain pipe downstream of a siphon provided in the flush line path downstream of the toilet bowl.
  • the toilet is further developed according to one or more of the preferred developments discussed in connection with the toilet flushing module.
  • the present invention provides a flushing module for bypassing a piece of furniture connected to a drinking and service water installation, having a line flushing valve which is assigned to a fresh water line supplying the piece of furniture with fresh water, a waste water line which can be connected to the piece of furniture, and a bypass line through which Fresh water, which is removed from the fresh water line through the line flushing valve, can be drained into the waste water line without flowing through the item of furniture.
  • a toilet bowl a urinal, a washbasin, a bidet, a bathtub or a shower tray.
  • the figure 1 shows a schematic representation of a first exemplary embodiment of a toilet flushing module that is integrated into a frame 2 of a pre-wall installation.
  • the toilet flushing module includes a cistern 4, which is shown as a rectangle in the drawing. A rinsing volume 6 of water is held in the cistern 4 and fills the cistern 4 up to a filling level 8 .

  • a bypass line 16 branching off transversely thereto is connected to the waste water pipe 14 , which is passed sealingly through an opening 18 at the bottom of the cistern 4 and whose inlet opening 20 is arranged at the level of the filling level 8 inside the cistern 4 .
  • This Bypass line 16 is mounted within frame 2 and connected to frame 2 .
  • the bypass line 16 is formed by a separate plastic tube.
  • the outlet opening 10 is assigned an outlet valve 22 for opening and closing the same.
  • the outlet valve 22 releases the outlet opening 10 by actuating or activating a triggering mechanism, not shown, so that the water in the flushing volume 6 flows out through the flushing line 12 into the toilet bowl.
  • the cistern 4 has an inlet opening 24 through which a fresh water line 26 carrying cold water is passed.
  • the fresh water line 26 divides into a first line path 26A and a second line path 26B, with a float valve as an inlet valve 28 for filling the cistern 4 up to the filling level 8 and at the end of the second line path 26B at the end of the first line path 26A motor-controlled line flushing valve 30 is provided for a hygiene measure.
  • a flow sensor 32 is provided upstream of the float valve 28 in the direction of flow, which registers a flow of fresh water through the line path 26A initiated by the opening of the float valve 28 .
  • the motor-controlled line flushing valve 30 is connected via a control line 34 to a control unit 36 provided inside the cistern 4 , which controls the opening and closing of the line flushing valve 30 and is connected to the flow sensor 32 and a temperature sensor 38 via signal lines 37 .
  • the control unit 36 opens the line flush valve 30 when the toilet has not been flushed for an extended period of time and/or is being flushed with very little water and/or a preset period of time has elapsed since the last flush and/or a predetermined time has elapsed. So the fresh water line 26 is subjected to a hygiene measure. The fresh water hygiene is additionally monitored by the temperature measurement of the temperature sensor 38 .
  • the water drained from the fresh water line 26 through the line flushing valve 30 during hygiene flushing is let into the flushing cistern 4 and mixes with the water filling already held in the flushing cistern, with the amount of water that exceeds the flushing volume 6 defined by the filling level 8 going into the bypass line 16 overflows and is directed into the sewage pipe 14 by bypassing the toilet bowl.

  • the figure 2 shows a second embodiment, which is basically constructed like the first embodiment.
  • the second line path 26B of the fresh water line 26 ends directly above the inlet opening 20 of the bypass line 16.
  • the water drained from the fresh water line 26 through the line flushing valve 30 is thereby fed directly into the bypass line 16 and does not mix with the water already in the cistern water filling.
  • This exemplary embodiment has the advantage over the first exemplary embodiment that the noise level during the hygiene measure is further reduced, since the water does not hit the water surface of the flushing volume noisily, but instead is introduced directly into the bypass line in an insulated manner
  • the figure 3 shows a third embodiment, which is basically constructed like the first embodiment.
  • the cistern 4 has a second inlet opening 42 through which a fresh water line 44 carrying hot water is passed, the end of which is assigned a motor-controlled hot water line flushing valve 46 .
  • the hot water line flushing valve 46 can be designed like the line flushing valve 30 and is controlled like the line flushing valve 30 by the control unit 36 via a control line 34 .
  • the draining of hot water from the hot-water-bearing fresh-water line 44 through the hot-water-line flushing valve 46 enables a hygiene measure for the hot-water-bearing fresh-water line 44 in addition to the hygiene measure for the cold-water-bearing fresh-water line 26.
  • the hot water line purge valve 46 may be located directly above the bypass line inlet port 20, as shown. But it can also be arranged so that the hot water runs into the cistern. Furthermore, any combination of the aforementioned arrangements is useful and encompassed by the present disclosure. For example, both line flushing valves 30, 46 for hot and cold water can be arranged directly above the inlet opening 20 of the bypass line
  • the cistern 4, the flushing line 12, the waste water pipe 14 and the bypass line 16 are each firmly connected to the frame 2 and form a structural unit with it, so that the flushing module can be installed by installing the frame 2 for a pre-wall installation.
