Definitions

  • the invention relates to a device for analyzing urine for connection to the drain area of a urinal or to a secondary drain of a composting toilet, comprising a pipe section with an inlet that can be connected to the urinal or to the secondary drain of the composting toilet, and an outlet located at the other end of the pipe section for connection to further drain lines.
  • the invention further relates to a composting toilet equipped with such a device.
  • the object of the present invention is therefore to create a device for analyzing urine which can also be retrofitted to existing toilets and urinals and which enables sample taking and automated measurement in a simple manner.
  • the device should be inexpensive to manufacture and be able to forward the measurement results via appropriate interfaces.
  • the device can be designed as an autonomous module and can be used over longer periods with little maintenance effort.
  • the pipe section comprises a measuring section which is located below the inlet and the outlet in the installed state and is designed as a siphon in a U-shape, with a first measuring area for at least one first sensor being provided adjacent to the inlet in the descending leg of the siphon and a second measuring area for at least one second sensor being provided within the lower bend section of the U-shaped section.
  • the measurements can thus be carried out in quick succession, with the system automatically recalibrating itself with each flush cycle.
  • at least two measuring areas are provided in the siphon for the measurement, with various sensors, such as pH probes, photosensitive sensors or the like, being arranged in the area of the lowest point and upstream of it.
  • the urine sample does not experience any significant dilution in the area of the siphon defined with the corresponding volume, but can be used for a measurement.
  • the siphon is completely rinsed out and all sensors are recalibrated for further use using the clear flushing water.
  • the first measuring range can also be used to detect when a measurement begins, activating the sensors further downstream when the first sensor measures a change.
  • the at least two sensors are connected to a control unit, wherein the control unit serves to process the measurement data received from the sensors and, if necessary, to compare them with stored values, and wherein the control unit has a communication interface, preferably for wireless communication, in order to transmit the determined or processed data to a terminal device.
  • the control unit serves to process the measurement data received from the sensors and, if necessary, to compare them with stored values
  • the control unit has a communication interface, preferably for wireless communication, in order to transmit the determined or processed data to a terminal device.
  • a communication interface preferably for wireless communication
  • the entire device including the siphon, electronics with interfaces, sensors and power supply, can also be very easily retrofitted as a compact module to existing separation toilets or urinals. Thanks to the self-contained structure, a health toilet can be created cost-effectively in a wide variety of areas, which can carry out continuous measurements and is particularly user-friendly in terms of operation and maintenance.
  • control unit can be connected to an electronically controlled flush of the urinal or the separate toilet in order to take over the flush control.
  • Some sensors require more time for the measurement process than might be possible when using the toilet.
  • a flushing process initiated by the user can be delayed accordingly, or manual flushing by the user is not required at all, as the control unit carries out the flush automatically after the measurement has been taken.
  • a temperature sensor is provided in the first measuring area. This represents a particularly simple way of triggering a measuring process via the first sensor located upstream in the siphon.
  • the temperature sensor measures an increase in the liquid temperature and then triggers the further measurements by the downstream sensors via the control unit with a corresponding delay.
  • an optical sensor with a transmitter for electromagnetic waves and an opposite receiver is provided in the first measuring area, with a pipe section of the first measuring area being designed as a cuvette through which the electromagnetic waves can pass.
  • Different parameters can be read out using a photosensitive sensor depending on the wavelength of the transmitter. By shining a light through the cuvette, turbidity can also be detected very easily, which can also be used as a trigger signal for the other sensors located downstream.
  • an electrical sensor is arranged in the second measuring area, which determines, for example, the pH value in the U-shaped pipe section. After the inflowing urine has displaced the previously present flushing water in the direction of the outlet, the measurement can be carried out here at an optimal concentration.
  • a further preferred embodiment provides that a sampling opening is provided in the second measuring area, to which a line with a pump is connected, which supplies a sample quantity taken to a measuring unit connected to the line, with a further discharge line running from the measuring unit back to the outlet area of the device in order to discharge the sample back into the outlet after the measurement has been carried out. If more complex measurements are to be carried out, for example by adding measuring strips or additional reagents, then it can be advantageous to take a sample at the corresponding point in the second measuring area after the measurement process has been triggered by detecting incoming urine in the first measuring area and to pass it on to a measuring unit.
  • This measuring unit can be equipped, for example, with a magazine of measuring strips or a reservoir for adding further reagents as well as the corresponding measuring sensors and the corresponding measuring electronics.
  • Sampling via a line with a pump has the further advantage that correspondingly time-consuming measurements can be carried out while the siphon of the device is already being flushed. After a rinse cycle, water can be taken from the siphon filled with fresh rinse water via the sampling opening in order to also rinse the line and the measuring unit.
  • the invention relates to a separation toilet comprising a shell with a pipe section connected in the drainage area with at least partially approximately vertical side walls, wherein a separate secondary drain is provided for separating urine, and wherein the inlet opening of the secondary drain is arranged on one side of the vertical side wall of the pipe section and thus below the shell and is rounded in the transition area at the upper edge of the inlet opening of the secondary drain to the vertical side wall of the pipe section, wherein a device for analyzing urine is connected to the secondary drain as described above.
  • a separation toilet without a corresponding device for analyzing urine is disclosed, for example, in WO 2019178622 A1.
  • This separation toilet has the advantage that a large part of the urine that occurs is led into the secondary drain without complex valves or visible separating structures within the shell.
  • the secondary drain provided is particularly suitable for connecting a device according to the invention for analyzing urine. During the rinsing process, enough rinsing water enters the device via the teapot effect at the inlet opening of the secondary drain to completely rinse out the siphon and reset it for the next measuring process.

  • a first sensor 7 detects the inflowing urine 22.
  • a temperature sensor can be provided as a sensor, for example, which detects the temperature increase and thus signals a control unit (not shown) to carry out a measuring process.
  • Fig. 2 shows the following time period in which the inflowing urine completely fills the siphon and has largely displaced the flushing water. Surprisingly, it has been shown that a slight dilution of the urine with flushing water has hardly any effect on the desired measurements and can therefore be neglected, which significantly simplifies the entire supply and sampling process.

  • the receiver 11 can also detect the start of a measuring process by a change in state in order to activate sensors located further downstream in the second measuring area 8 via the control unit. During flushing, the receiver 11 is recalibrated against an initial value.
  • Fig. 5 shows a schematic representation of a further embodiment of the invention.
  • reagents must be added to the urine 22 or test strips must be wetted. Since these reagents represent a more expensive consumable, it is desirable to keep the sample quantity low.

  • a small amount of urine 22 is fed to a measuring unit 16 via a pump 15 via a line 14 connected to the sample extraction opening 13.
  • the sample is returned to the pipe section via a drain 17 near the outlet 4 and disposed of.
