Definitions
- the invention relates to a sanitary fitting with an electrically operated valve for controlling a flow of water through the sanitary fitting, with a first designed as a proximity switch switch for opening the valve and with a mechanically operated control element for setting a further function of the sanitary fitting.
- Sanitary fittings are known as e.g. Faucets that are turned on by a proximity switch and turn off automatically after a predetermined period of time.
- such sanitary fittings also have a tempering lever for manually setting the water temperature. This results in terms of the arrangement of the tempering lever restrictions. The tempering must namely be arranged so that its operation is not accidentally operated the proximity switch, as this would irritate an operator and in the worst case even the risk of scalding with too hot water could result.
- the object is achieved by a sanitary fitting with the features of claim 1.
- Advantageous embodiments can be found in the dependent claims.
- the sanitary fitting has an electrically operated valve, with a water flow through the sanitary fitting on and off can be.
- a first switch designed as a proximity switch serves to open the valve and thereby trigger the flow of water.
- the sanitary fitting has a further, mechanically operable control element, which serves to regulate a further function of the sanitary fitting.
- a second switch is provided, which is assigned to the mechanically actuatable operating element and serves for the electrical locking of the first switch. The second switch is arranged such that it responds to an operation of the further control element.
- the first proximity switch and the mechanically operable control element can be arranged at a small spatial distance from each other, without the risk that it comes to false alarms.
- the user is given a sense of higher quality of the sanitary fitting due to the invention.
- the second switch is also designed as a proximity switch.
- Such a solution has a particularly low susceptibility to errors.
- the switches can be designed as infrared sensors or as capacitive sensors. These sensors are particularly reliable and practical.
- the sanitary fitting on a programmable controller which is connected to the first and the second switch and which is programmed so that they on an actuation of the first switch a Output control signal for opening or closing the valve and prevents the output of the control signal for a predetermined period of time only upon actuation of the second switch, which takes place before the output of the control signal.
- Locking therefore only takes place if no water flow has been triggered yet. After triggering a water flow, the locking function is reversed, i. If the water flow was already triggered, after actuation of the second switch, an actuation of the first switch and thus the closing of the solenoid valve is locked for a vor ⁇ certain period of time.
- This will allow the operator to perform a function of the sanitary fitting such as e.g. the water temperature can be set as usual with one hand in the water jet and with the other on the temperature control lever according to subjective sensation.
- control device is programmed so that it turns off the flow of water through the valve after expiry of a shutdown timer and the actuation of the second switch, which takes place after the output of the control signal resets the shutdown timer.
- the sanitary fitting has, as a further function, a mixer for regulating the water temperature.
- the mechanically operable control element in this embodiment is a temperature control lever for operating the mixer.
- the further function is a regulation of the amount of water.
- the sanitary fitting has a substantially cylindrical base body, on the head piece of the first switch is arranged.
- Such a sanitary fitting can be very easy and intuitive to use even with not familiar with the operation operators.
- Figure 2 is a block diagram of a control device for the sanitary fitting of Figure 1
- FIG. 3 shows a flow chart of the control program for the control device from FIG. 2.
- FIG. 10 A schematic view of a sanitary fitting 10 is shown in FIG.
- the sanitary fitting 10 has a cylindrical base body 17, on whose front side a forwardly directed outlet pipe 18 is arranged. Inside the sanitary fitting an electrically operated valve is housed (not shown), via which a water flow can be switched on and off.
- a proximity switch 12 is housed, via which the valve is actuated.
- a mixer (not shown) which is connected to domestic hot and cold water connections and mixes incoming hot and cold water in an adjustable ratio.
- a tempering lever 14 is provided, which is attached to the rear side of the sanitary fitting 10 relative to the water outlet pipe 18. By lateral pivoting of the temperature control lever 14, the mixing ratio is set in the mixer.
- a proximity switch in the sense of this description is a switch with non-contact characteristic, which detects an approach, for example, by hand and changes the switching state in response to an approximation.
- Various types of proximity switches are known.
- the proximity switch is realized with a capacitance sensor. Equally suitable but also, for example, infrared sensors.
- FIG. 2 shows the control device 16 in a block diagram. To the control device 16, the proximity switch 12 and the further capacitance sensor 16 are connected. An output of the controller 16 leads to a valve driver 19 which is connected to the electrically operated valve 11.
- the running in the control device 16 control and monitoring program generates upon actuation of the proximity switch 12, a signal for the valve driver 19.
- the valve driver 19 then applies an operating voltage to the electrically operated valve 11, so that the valve 11 opens.
- the proximity switch 12 is locked for a predetermined period of time, i. switched functionless, so that no signal can be generated for the valve driver. This prevents unintentional triggering of the water flow when the actuation of both switches 12 and 15 takes place within the defined time window.
- the control and control program is adapted so that the operation of the lock is reversed, when the flow of water in the operation of the tempering lever has already been triggered, ie a closing of the valve 11 by re-actuation of the proximity switch 12 is suppressed for a predetermined period of time the possibility exists that the operator can set the temperature as usual with one hand in the water jet and the other hand on Temperierhebel 14 according to subjective feeling, without the proximity switch 12 when grasping for the temperature control lever 14 accidentally responds and shuts off the flow of water again.
- a shutdown timer which closes the valve 11 via the valve driver 19 again after a predetermined period of time and thus shuts off the flow of water again.
- This shutdown timer is reset when the second switch 15 is operated.
- FIG. 3 A flow chart of the control program is shown in FIG. 3 in the form of a flowchart.
- an interrupt is triggered in step 301, which starts the control and monitoring program.
- step 302 it is then checked in step 302 whether switch 12 (Sl) or switch 15 (S2) has been actuated. If switch S2 has been actuated, a timer for switch S2 is set in step 303 and the control and monitoring program is acknowledged in step 312. On the other hand, if Sl is pressed, it is then checked in step 304 whether the timer for S2 has expired. If this is not the case, then the control and monitoring program without further steps immediately acknowledged.
- the switch Sl is thus locked after operation of S2 for a predetermined period of time, ie until the expiration of the timer for S2.
- the timer for S2 thus serves to set the period during which the switch S1 is locked.
- step 304 determines whether the timer for S2 had expired upon actuation of Sl, i. the switch Sl was not locked.
- step 305 sets a timer for Sl.
- step 306 it is checked in step 306 whether the timer for Sl has already expired. As long as the timer for Sl has not yet expired, it is now checked in step 307 in the form of a loop whether S2 has been actuated. If S2 is actuated as long as the timer for Sl has not yet expired, then in step 308 the timer for S2 is set and the control and monitoring program is acknowledged in step 312.
- the timer for Sl thus serves to set the time window during which, when both switches are actuated, an interlocking of Sl takes place in order to prevent unintentional triggering of the water flow.
- step 309 If S2 is not actuated before the timer expires, it is now checked in step 309 whether the valve is closed. If the valve is open, it is closed in step 310, a timer for the "closed duration" is set and the control and monitoring program is acknowledged in step 312. The valve now remains closed for at least a period of this "closed duration" and can not This will prevent unstable situations in which the valve opens and closes at short intervals. ⁇
- step 312 a timer for the "open duration" is set and the control and monitoring program is acknowledged in step 312. The valve now remains open until the timer expires "opened before, if in the meantime, neither of the two switches Sl or S2 is pressed, is automatically closed again.
- the switch 15 may also be designed so that it operates touch-sensitive. Instead of capacitance sensors, the sanitary fitting 10 can be carried out with any other sensor technology, provided at least one of the switches 12, 15 operates without contact. Instead of a capacitance sensor, the switch 15 may alternatively be realized with one or more micro-switches, which are arranged inside the body of the sanitary fitting 10 so that upon pivoting of the temperature control lever 14 at least one of the microswitch is depressed by the temperature control lever 14. As a result, an actuation of the temperature control lever is also detected and can be used in the manner explained for locking the proximity switch 12.
