Definitions

  • the invention relates to a method for controlling a pump which is fluidically arranged in a discharge line of a shower arrangement for pumping out shower water.
  • the invention also relates to a control device and a shower arrangement for carrying out such a method and an associated storage medium.
  • shower assemblies are typically used to clean standing or seated persons with a directed jet of water.
  • a shower fitting is typically used for this purpose, which is supplied with water, in particular with hot and cold water, through one or more inlets and which can be actuated by a user in such a way that the desired shower effect is produced.
  • this has the advantage that shower water is reliably prevented from escaping from the shower arrangement, it has proven to be disadvantageous in the course of the increasing demand for disabled-friendly design of shower arrangements, since the typically raised tray prevents people with walking frames or wheelchairs from to get to an area where they can take a shower.
  • a floor-level design of shower trays is typically not readily possible, especially when converting old buildings, since there is no longer a sufficient gradient for the reliable drainage of shower water. Therefore, in such cases, pumps can be used which can actively pump out shower water.
  • the invention relates to a method for controlling a pump which is fluidically arranged in a discharge line of a shower arrangement for pumping out shower water.
  • the procedure has the following steps:
  • a drain line can in particular be connected to a shower tray, which can in particular be a floor-level shower tray.
  • a shower tray which can in particular be a floor-level shower tray.
  • Such floor-level shower trays typically enable disabled people with auxiliary devices such as walkers or wheelchairs to enter a shower arrangement without barriers.
  • the pump makes it possible for a drain of the shower tray to also be arranged below a drain pipe or at least at a height which would not ensure a sufficient gradient to a drain pipe.
  • the pump actively sucks off existing shower water and disposes of it appropriately.
  • a fluidic arrangement is understood in particular to mean that the pump is arranged in the drain line in such a way that it can suck in shower water from one part of the drain line and discharge it into another part of the drain line.
  • the pump output signal specifies how strongly the pump should pump, or whether it should pump at all.
  • the pump performance signal can be in the form of a simple on/off signal.
  • the pump performance signal can in particular assume a constant value which is taken when the pump power signal is to be in the "on" state, and may be zero when the pump power signal is to be in the "off” state.
  • a constant value can be permanently programmed, for example, or it can be adjustable by means of an input device or a controller.
  • the constant value can specify the desired output or delivery rate of the pump.
  • the pump performance signal can also specify a graded and/or continuously adjustable performance or delivery rate with which the pump is to be operated. By means of the pump power signal, one of a number of predetermined power levels can be selected, for example, or a power can be set on a continuous scale.
  • Operating the pump as a function of the pump output signal can mean in particular that the pump output signal is used as at least one input variable or also as the only input variable for controlling the pump.
  • the drain sensor signal preferably includes data or other values indicative of flow through the drain line. It is typically generated in a suitable manner by the outflow sensor or a downstream unit. In particular, the drain sensor generates the drain sensor signal based on flow through the drain line.
  • the outflow sensor signal can also be a purely analog signal.
  • a deviation between the pump performance signal and the discharge sensor signal, or a value dependent on the discharge sensor signal is determined. If the deviation is at least as great as a threshold value, an error message is advantageously output.
  • This can be an absolute or a relative deviation, for example, which can be specified accordingly. This enables the functionality of the pump to be monitored. It can typically be assumed that each pump output signal requires a specific pump output. If the deviation is at least as large as a threshold value, this typically means that the pump is delivering too much or too little. For example, the deviation can be seen as an absolute value before it is compared to the threshold. However, as an alternative, separate threshold values can also be specified for a positive deviation or a negative deviation.
  • the pump delivers too little, in the second case the pump delivers too much.
  • a value dependent on the outflow sensor signal can be used in particular if the outflow sensor signal is not to be compared directly with the pump performance signal.
  • a calculation rule can be used, for example, which specifies the value as a function of the outflow sensor signal.
  • the error message can be sent, for example, via a wired or wireless connection, in particular to a monitoring device or evaluation device. It can also be sent to an alarm device which, for example, can emit an optical and/or acoustic warning signal in response to the error message.
  • the pump is regulated depending on the outflow sensor signal. This allows immediate use of the discharge sensor signal to improve control of the pump. The pumping performance can thus be improved, while energy can be saved at the same time.
  • the pump can be regulated based on the pump performance signal.
  • the pump performance signal can specify a target value, for example.
  • the pump can be operated in such a way that it is regulated to the pump power signal, in particular as a function of the outflow sensor signal.
  • a proportional controller, a proportional-integral controller, or a proportional-integral-derivative controller can be used.
  • the pump performance signal can be used as a reference variable and the discharge sensor signal can be used as a controlled variable.
  • a value can also be used as a reference variable, which is calculated using a calculation rule based on the pump performance signal.
  • a value can also be used as the controlled variable, which is calculated using a calculation rule based on the outflow sensor signal.
  • the pump output signal is specified continuously, and in particular the outflow sensor signal is received continuously at the same time. This allows the signals to be used simultaneously.
  • Continuous can also include the use of the same time intervals when specifying or receiving over a certain period of time.
  • the outflow sensor can only measure a flow through the outflow line when the outflow line is completely full. According to one embodiment, it can measure a flow through the discharge line even when the discharge line is completely full, which can mean in particular that it can measure both when the discharge line is completely full and when it is only partially full.
  • the outflow sensor can in particular be designed accordingly.
  • the outflow sensor is not a level sensor.
  • Level sensors do not measure the flow, only the fleas on a water surface. They are typically unsuitable for the purposes relevant here.
  • an ultrasonic sensor can be used as the outflow sensor. Such has proven itself for typical applications.
  • it can be arranged on or in the drain line in such a way that ultrasonic waves run through draining shower water and a flow can thus be measured.
  • a sensor which does not come into contact with the water flowing in the drain line can be used as the drain sensor. This avoids contamination of the sensor.
  • the pump output signal can be specified in particular by receiving an inflow sensor signal from at least one inflow sensor or by calculating it as a function of at least one inflow sensor signal received from an inflow sensor.
  • an inflow sensor can measure a flow through an inflow line in front of a shower fitting.
  • the inflow sensor can also measure a flow through a shower hose to a shower fitting.

  • a shower faucet it is typically a device that is provided with elements such as knobs or levers to give a user the ability to set the amount of water, temperature and possibly a distribution of running shower water to different shower elements such as shower heads or body sprays.
  • An inflow line is typically a line which supplies such a shower fitting with water.
  • separate supply lines for hot water and cold water can be used.
  • the inflow sensor can generate the inflow sensor signal based on a flow through the inflow line or a shower hose. It should be understood that multiple inflow sensors are also possible, with the pump output signal being generated from inflow sensor signals generated by these inflow sensors.
  • an inflow sensor for hot water and an inflow sensor for cold water can be used.
  • An inflow sensor can be designed in particular for the direct measurement of the flow, ie in particular not as a level sensor.
  • the pump can in particular be controlled or regulated by comparing the inflow and outflow. This allows better control of the pump, for example to ensure sufficient pump performance while avoiding excessive energy consumption.
  • the inflow sensor signal is received wirelessly from the inflow sensor. This enables the inflow sensor to be positioned particularly freely. According to one embodiment, the inflow sensor signal is received by wire from the inflow sensor. This enables a simple design and a waiver of radio components.
