Definitions

  • the present invention relates to a sanitary fitting, comprising a cold water line, a hot water line, a mixing element, a mixed water line and a display.
  • the invention also relates to a method for operating a sanitary fitting.
  • sanitary fittings are known in which the temperature of the mixed water in the mixed water line is determined by a temperature sensor and the mixed water temperature is signaled to the consumer by means of a suitable display.
  • a temperature sensor determines the temperature of the mixed water in the mixed water line.
  • the mixed water temperature is signaled to the consumer by means of a suitable display.
  • Such a direct determination of the mixed water temperature for setting the display is associated with the considerable disadvantage that only the current mixed water temperature is displayed, which can be subject to significant fluctuations.
  • the water in the hot water pipe cools down when the sanitary fitting is closed, it drops to room temperature, so that when the hot water pipe is opened, a temperature is initially displayed that can suddenly increase, so that there is a risk of a user being scalded.
  • DE 10 2012 100 097 B4 propose detecting the angle of rotation of an actuating element of a mixing element and using the angle of rotation to display a temperature that is likely to occur in the mixed water line.
  • such an arrangement presupposes that the sensor is calibrated to the actuating element.
  • the object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and in particular to specify a sanitary fitting with which a user can be prevented from being scalded in an alternative and simple, in particular energy-saving manner.
  • the sanitary fitting includes a cold water line, which can preferably be connected to a cold water line of a building with a cold water connection.
  • the sanitary fitting also includes a hot water line, which preferably has a hot water connection to the hot water house line of a building or, for example, to the hot water outlet of an instantaneous water heater.
  • the cold water line and the hot water line lead to a mixing element.
  • a mixed water line is connected to the mixing element, which leads in particular to a mixed water outlet of the sanitary fitting.
  • the mixing element has in particular an adjusting element that can be adjusted manually or by a controller, with which the cold water volume flow flowing from the cold water line into the mixed water line and the hot water volume flow flowing from the hot water line into the mixed water line can be adjusted. Accordingly, the temperature of the mixed water can be set via the mixing element.
  • the mixing element can be designed, for example, as a single-lever mixer or as a classic two-handle fitting.
  • the sanitary fitting also preferably comprises a fitting body in which the cold water line, the hot water line, the mixing element and the mixed water line are arranged or at least attached.
  • the sanitary fitting also includes a display.
  • the display can be a digital display that displays numerical values.
  • the display can also have a number of fields, with fewer fields being activated to display a supposedly lower mixed water temperature and more fields being activated to display a supposedly higher mixed water temperature.
  • the display is integrated into the body of the fitting, so that the display can be perceived by a user.
  • the display can, for example, be on a top side of the sanitary fitting be arranged.
  • the display illuminates a surface or an area, so that the display can be perceived over the illuminated area.
  • the display has at least one light source for emitting light with different colors, the color of the light being variable.
  • the display can have at least one first light source for emitting light with a first emission color and at least one second light source for emitting light with a second emission color, the at least one first light source and the at least one second light source being arranged in relation to one another such that the light emitted by the light sources is mixed in such a way that a user only perceives the mixed light and thus the color of the mixed light produced by the light mixing.
  • the light sources are embodied in particular as LEDs which are arranged in the immediate vicinity of one another and the light emitted from them is mixed into light which can be perceived by a user.
  • the sanitary fitting has a first sensor for determining a cold water volume flow in the cold water line, which is also referred to as a cold water volume flow sensor.
  • the sanitary fitting has a second sensor for determining a hot water volume flow in the hot water line, which is also referred to as a hot water volume flow sensor.
  • volume flow rate sensors are designed and arranged in such a way that the volume flow rate in the corresponding water pipe can be inferred from a signal (e.g. a voltage) emitted by the volume flow rate sensor, particularly if parameters (such as diameter) of the water pipe are known.
  • the output signal of such volume flow sensors therefore depends on the volume flow flowing through the associated water pipe.
  • the volume flow in the water pipe is not only indirectly inferred by other parameters (such as the orientation of an actuating element of a mixing element).
  • the display is changed as a function of the cold water volume flow and the hot water volume flow.
  • the function can be a quotient between the cold water volume flow and the hot water volume flow or a difference between the cold water volume flow and the hot water volume flow. If the quotient that can be determined by the cold water volume flow sensor and the hot water volume flow sensor or the difference that can be determined changes, the display also changes.
  • the display shows a visualization that represents the expected temperature of the mixed water based on the volume flows, and is therefore independent of the current absolute temperature of the mixed water.
  • the mixing element of such a sanitary fitting is set in such a way that only hot water flows when the sanitary fitting is opened, a visualization representing a high mixed water temperature is immediately displayed, even if the water exiting the mixed water line initially has a very low temperature (roughly room temperature). having.
  • Such a sanitary fitting is particularly useful in heavily frequented sanitary rooms, since users are not familiar with the characteristic temperature curves of such sanitary fittings that are unknown to them.
  • one is based on the volume flows of the hot and cold water Display is also particularly useful if the mixing element is not set directly manually by the user (as in the case of a single-lever mixer or a two-handle mixer), but by an electronic control.
  • the color of the light emitted by the at least one light source of the display and perceived by the user changes as a function of the cold water volume flow and the hot water volume flow. For example, with a change in the ratio of the volume flows, which corresponds to an assumed increase in temperature, the color of the light can be changed to reddish, while with a change in the ratio of the volume flows, which corresponds to an assumed decrease in temperature, the color of the perceptible light is changed to bluish.
  • the cold water volume flow sensor is directly connected to the at least one first light source, for example a blue light-emitting LED, while the hot water volume flow sensor is directly connected to the at least one second light source, for example a red light-emitting LED .
  • the volume flow sensors generate a signal that is proportional to the volume flow in the corresponding water pipe.
  • the respective volume flow sensor can output a higher voltage as the volume flow increases.
  • the at least one first light source and the at least one second light source are preferably designed so that with the Volume flow sensors provided voltages as input voltages, the light intensity emitted by the light sources increases.
  • the volume flow sensors can thus be connected directly to the light sources, which keeps the circuitry effort very low.
  • the sanitary fitting has a controller and in particular a controller for setting the display, the controller being connected to the cold water volume flow sensor and the hot water volume flow sensor and to the display.
  • the controller is connected to the at least one light source of the display.
  • Such a controller can also be connected to a drive for an actuating element of the mixing element.
  • the cold water volume flow sensor and the hot water volume flow sensor are each arranged as a turbine in the cold water line and the hot water line, for example, so that the voltage generated by the turbine can be applied directly to a light source.
  • Such turbines can also serve as a power source for the display and/or a controller, so that no separate power source is required.
  • the sanitary fitting shown comprises a cold water line 1 in which a cold water flow rate sensor 6 is arranged, and a hot water line 2 in which a hot water flow rate sensor 7 is arranged.
  • the cold water line 1 and the hot water line 2 lead to a mixing element 3 designed, for example, as a single-lever mixing cartridge, to which a mixed water line 4 leading to a mixed water outlet is connected.
  • the mixing element 3 With the mixing element 3, the ratio of hot water and cold water in the mixed water line and thus the temperature of the mixed water can be adjusted.
  • the sanitary fitting also includes a display 5 with a first light source 5.1 and a second light source 5.2.
  • the display 5 is connected to the cold water volume flow sensor 6 and the hot water volume flow sensor 7 .
  • the first light source 5.1 is, for example, an LED that emits blue light
  • the second light source 5.2 is, for example, an LED that emits red light.
  • the display 5 is set up in such a way that the color of the light emitted by the display 5 is changed as a function of the ratio of cold water volume flow and hot water volume flow determined by the volume flow sensors 6 and 7 . For example, if only cold water flows, blue light is emitted. On the other hand, when only hot water flows, light of red color is emitted. In this way, an assumed temperature of the mixed water is displayed, so that the display 5 is not subject to any fluctuations in the temperature of the hot or cold water.
