Definitions

  • the invention relates to a system for reusing slightly soiled process water, in particular shower or bath water.
  • the invention also relates to a compact flush-mounted temporary storage module for such a system.
  • the module is used for the temporary storage of shower or bath water and the supply of flushing water to concealed toilet cisterns, mainly designed for use in the sanitary area of private households.
  • the present invention is therefore based on the object of presenting a practical implementation of a solution for saving fresh water in the sanitary area.
  • a first aspect of the invention relates to an intermediate storage module for process water, such as shower and/or bath water, for reducing fresh water consumption in the sanitary area.
  • such an intermediate storage module comprises a frame for hanging the intermediate storage module on a wall or for fastening the intermediate storage module in a wall Lightweight stud wall and a container carried by the frame to hold the process water with a capacity of 60 to 100 liters.
  • the tank is equipped with an inlet connection for the service water, a fresh water connection with an inlet valve which opens the fresh water connection when the water level in the tank falls below a minimum water level, a drain connection for connecting the tank to the water supply of a toilet cistern ideally located below the tank, a overflow connection and a condensation opening.
  • the container preferably does not exceed the following maximum dimensions: 50 cm wide, 100 cm high and 20 cm deep.
  • the compact design ensures that the temporary storage module (preferably concealed) can be installed or retrofitted in the sanitary area.
  • the inlet valve of the fresh water connection can be or include a float valve or a level control valve.
  • the minimum water level is preferably chosen so that at least as much water is held in the tank as the connected toilet cistern can hold.
  • the water level always means the volume of the water in the container, not necessarily the height of the water column. In the case of a container with a constant cross-section in the vertical direction, both quantities are of course proportional to each other.
  • the inlet valve preferably has an actuator (for example an adjusting screw, a handwheel, a stop or the like) via which the minimum water level can be set manually when the intermediate storage module is installed.
  • an actuator for example an adjusting screw, a handwheel, a stop or the like
  • the inlet valve can be designed and/or installed in such a way that it can be set at which water level in the container the inlet valve interrupts the fresh water supply through the fresh water connection again.
  • the water level at which this occurs preferably does not exceed 30% (better: 15%) of the maximum water level specified by the overflow connection.
  • the inlet valve could have an actuator which can be used to set the water level in the container from which the inlet valve interrupts the supply of fresh water through the fresh water connection again.
  • the Actuators with which it is possible to set the water levels at which the inlet valve opens or closes could be separate actuators or combined in a combined actuator.
  • the water level at which the inlet valve interrupts the fresh water supply again could also be adjusted via the mounting height of the inlet valve.
  • the container is preferably equipped with an inspection closure, which can be designed as a screwable cover.
  • the container can have any shape, but a cuboid configuration of the container is preferred.
  • the top and bottom sides of the container preferably represent the smallest side surfaces of the cuboid, while the front and rear side of the container represent the largest side surfaces.
  • the condensation opening is located above the maximum water level (which is specified by the overflow), preferably at the top of the container.
  • a further aspect of the invention relates to a system for reducing fresh water consumption in the sanitary area, comprising an intermediate storage module as described above, and a toilet cistern connected to the drain connection and having a low-pressure float valve.
  • this further comprises a small lifting pump connected to the inlet connection for pumping service water up from a drain, for example a shower, bathtub or washbasin or bidet, into the container.
  • a drain for example a shower, bathtub or washbasin or bidet
  • the small elevating pump can include an integrated cutter, which crushes possible solids and is thus able to reduce the risk of deposits and/or blockages in the intermediate storage module.
  • the small lifting pump preferably has a delivery rate in the range from 15 l/min to 40 l/min, for example around 30 l/min.
  • the small elevating pump can be equipped with a non-return valve on the outlet side so that no water flows back when the small elevating pump is switched off.
  • the upstream buffer tank would preferably be connected to a sewage pipe connected overflow, which would ensure that the water from the shower, bathtub, washbasin or bidet is discharged even if the small lifting pump is defective.
  • the small lifting pump is preferably controlled via one or more sensors arranged on the inlet side (for example water level sensors arranged in the buffer tank).
  • FIG. 2 shows a view of a system according to the invention according to an example arrangement in a bathroom with shower and bath.
  • the system off 2 includes two as in 1 cache modules shown. Additional cache modules could be added as needed, increasing the storage capacity of the system.
  • the temporary storage modules are supplied with slightly dirty process water from the bathtub and shower via a small lifting pump 10 .
  • the toilet which is equipped with a conventional cistern (in this case with a concealed cistern) is located below the temporary storage module.
  • the intermediate storage module is a water storage module with a capacity of between 60 and 100 liters.
  • the module is used for the intermediate storage of shower or bath water (system water) and the supply of (concealed) toilet cisterns with the required flushing water.
  • the modular design simplifies the combination of several modules to increase capacity in larger households and simplifies retrofitting.
  • the module is installed above a concealed toilet cistern. Since the water supply between the intermediate storage module and the cistern occurs purely via the water column, it must be noted during planning and installation that the former always has a gradient to the cistern.
  • Several toilet cisterns can also be connected to one or more intermediate storage modules. The toilet cisterns do not necessarily have to be in the same room as the intermediate storage module or modules.
  • the container 2 has a maximum module width of 50 cm and is therefore adapted to the usual installation dimensions in the toilet and bathroom area. If, due to the room layout, it is not possible to install it directly above the toilet flush, it can of course be installed elsewhere.
  • the water supply is ensured through the inlet connection 3 in conjunction with a small lifting station 10.
  • This is installed, for example, in the flush-mounted housing of the cistern, the shower or the bathtub.
  • the only slightly contaminated shower or bath waste water is fed into the storage module.
  • Other possibilities in which slightly contaminated waste water can be used are also conceivable.
  • the water in the tank 2 is fed to the toilet cistern via the connection 5 provided for this purpose. Since there is not a large build-up of pressure between the storage module and the cistern, a low-pressure float valve 9 is preferably used instead of the usual float valve in the toilet cistern.
  • the condensation opening 8 in the top of the container is used on the one hand to maintain pressure equalization and to contain condensation.
  • a ventilation grille is also installed in the double wall, which closes the sanitary area to the storage module, in the area of the condensation opening mentioned.
  • the small lifting station 10 preferably has a backflow preventer (e.g. a non-return valve) on the pump outlet side, which prevents backflow in the direction of the shower or bathtub drain when the pump is not running.
  • a backflow preventer e.g. a non-return valve
  • the small lifting station 10 preferably has a capacity of about 30 l/min.
  • it preferably has an integrated cutting unit in order to reduce possible solids and to prevent deposits and blockages in the module as far as possible.
  • the water can be conveyed by means of integrated floor drain pumps or integrated pumps in shower drainage channels.
  • a drain strainer should be provided at a suitable point, which ensures a finer filtering of the service water from the shower or bath than usual, in order to keep the risk of blockages low.
  • the low-pressure float valve 9 is preferably implemented in a design with small dimensions in order to enable installation in standard concealed cisterns.
  • the sizing of the low pressure float valve 9 connection should preferably be equal to or greater than 1/2 inch (1.27 cm) to ensure rapid refilling of the cistern at high flow and low pre-pressure.
  • the diameter at the valve opening should preferably be greater than 3 mm in order to avoid possible blockages caused by the smallest solids.
