Description
[0021] The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show particularly preferred variants of the embodiment of the invention, but the invention is not limited thereto. The same reference numerals are used for the same components in the figures. In an exemplary and schematic manner
[0022] FIG. 1 shows a first variant of the embodiment of a sanitary device;
[0023] FIG. 2 shows a second variant of the embodiment of the sanitary device; and
[0024] FIG. 3 shows a third variant of the embodiment of the sanitary device.
[0025] FIG. 1 shows a first variant of the embodiment of a sanitary device 1, which is designed in the manner of a shower. The sanitary device 1 has a first dispenser 2 in the form of a shower head, which is connected to a first thermostat 6 via a first mixed-water line 7. Warm water can be routed to the first thermostat 6 from a warm-water source 15 via a warm-water supply line 16 and cold water can be supplied to the first thermostat 6 from a cold-water source 17 via a cold-water supply line 18. For this purpose, the first thermostat 6 has a warm-water input 19 for the warm water and a cold-water input 20 for the cold water. In a fresh water operating mode of the sanitary device 1 or of the first thermostat 6, the first thermostat 6 can be used to mix the warm water and cold water to form mixed water having a mixed-water set-point temperature. A user of the sanitary device 1 can use an actuating element 21 to set the mixed-water set-point temperature. The first mixed-water line 7 is connected to a first mixed-water outlet 22 of the first thermostat 6, such that the mixed water can be supplied to the first dispenser 2 via the first mixed-water line 7. The mixed water can be discharged through the first dispenser 2 into a basin 4, which is designed here in the manner of a shower tray. The basin 4 has a waste 5 at its basin bottom 13, through which the mixed water can be routed to an overflow tank 9 via a first waste line 14. The overflow container 9 has a receiving space 23, in which a liquid or the mixed water can be collected up to a maximum liquid level 24. When the maximum liquid level 24 is reached, excess liquid or excess mixed water can be discharged to a public sewer system 26 via an overflow 10 of the overflow tank 9 and a second waste line 25. After a changeover of the sanitary device 1 or the first thermostat 6 to a circulating operation mode, the liquid or the mixed water located in the receiving space 23 can be supplied to the first thermostat 6 as circulating liquid via a circulating-liquid supply line 27. For this purpose, a container discharge opening 28 of the receiving space 23 of the overflow container 9 is connected to a circulating-water input 29 of the first thermostat 6. Furthermore, a pump 11 is arranged in the circulating-liquid supply line 27, which can be used to pump the circulating liquid to the first thermostat 6. In the circulating mode of operation, the first thermostat 6 can be used to mix the circulating liquid with the warm water and/or the cold water by to form a temperature-controlled circulating liquid having a desired circulating-liquid set-point temperature. The circulating-liquid set-point temperature is equal to the mixed-water set-point temperature and can also be set via the actuating element 21 of the first thermostat 6. The temperature-controlled circulating liquid can be supplied to the first dispenser 2 via the first mixed-water line 7, such that the temperature-controlled circulating liquid circulates in a circuit as long as the sanitary device 1 or the first thermostat 6 is in the circulating operating mode. After switching the sanitary device 1 or the first thermostat 6 to the fresh water operating mode, the pump 11 is stopped to keep the circulating liquid from circulating. In the fresh-water operating mode, only mixed water from the warm water and cold water is dispensed via the first dispenser 2.
[0026] FIG. 2 shows a second variant of the embodiment of the sanitary device 1, which is also designed in the manner of a shower. The second variant of the embodiment of the sanitary device 1 differs from the first variant of the embodiment of the sanitary device 1 shown in FIG. 1 in that the mixed water can be routed from the first thermostat 6 to the first dispenser 2 via the first mixed-water line 7, and the circulating liquid can be routed to a second dispenser 3 via a second mixed-water line 8. In this way, the mixed water and the circulating liquid can be routed to the dispensers 2, 3 via separate mixed-water lines 7, 8. The first thermostat 6 has a first mixed-water outlet 22 for the first mixed-water line 7 and a second mixed-water outlet 30 for the second mixed-water line 8. It has to be emphasized that the mixed water can also be routed to a single or joint dispenser, for instance the first dispenser 2 via the first mixed-water line 7 and the circulating liquid via the second mixed-water line 8. In this case, the single or first dispenser 2 can have separate waterways for the mixed water and the circulating liquid, such that the mixed water and the circulating liquid can be routed separately until they are dispensed. In all other respects, the second variant of the embodiment of the sanitary device 1 is configured identically to the first variant of the embodiment of the sanitary device 1 shown in FIG. 1, such that the description of the first variant of the embodiment can be transferred to the description of the second variant of the embodiment.
[0027] FIG. 3 shows a third variant of the embodiment of the sanitary device 1, which is also designed in the manner of a shower. The sanitary device 1 has a first dispenser 2 in the form of a shower head connected to a second thermostat 12 via a first mixed-water line 7. Warm water can be routed to the second thermostat 12 from a warm-water source 15 via a warm-water supply line 16 and cold water can be supplied to the first thermostat 6 from a cold-water source 17 via a cold-water supply line 18. For this purpose, the second thermostat 12 has a warm water input 19 for the warm water and a cold-water input 20 for the cold water. In a fresh-water operating mode of the sanitary device 1, the second thermostat 12 can be used to mix the warm water and the cold water to form mixed water having a mixed-water set-point temperature. The mixed-water set-point temperature can be set by a user of the sanitary device 1 via an actuating element 21 of the second thermostat 12. The first mixed-water line 7 is connected to a first mixed-water outlet 22 of the second thermostat 12, such that the mixed water can be supplied to the first dispenser 2 via the first mixed-water line 7. The mixed water can be discharged through the first dispenser 2 into a basin 4, which is designed here in the manner of a shower tray. The basin 4 has a waste 5 at its basin bottom 13, through which the mixed water can be routed to an overflow tank 9 via a first waste line 14. The overflow container 9 has a receiving space 23, in which a liquid or the mixed water can be collected up to a maximum liquid level 24. When the maximum liquid level 24 is reached, excess liquid or excess mixed water can be discharged to a public sewer system 26 via an overflow 10 of the overflow tank 9 and a second waste line 25. After a changeover of the sanitary device 1 to a circulating operation mode, the liquid or the mixed water located in the receiving space 23 can be routed to the first thermostat 6 as circulating liquid via a circulating-liquid supply line 27. For this purpose, a container discharge opening 28 of the receiving space 23 of the overflow container 9 is connected to a circulating-water input 29 of the first thermostat 6. Furthermore, a pump 11 is arranged in the circulating-liquid supply line 27, which can be used to pump the circulating liquid to the first thermostat 6. The circulating liquid can be mixed with the warm water by the first thermostat 6 in the circulating mode of operation to form a temperature-controlled circulating liquid having a desired circulating-liquid set-point temperature. The first thermostat 6 is coupled to the second thermostat 12 such that the actuating element 21 of the second thermostat 12 can be used to set the circulating-liquid set-point temperature, and the circulating-liquid set-point temperature is equal to the mixed-water set-point temperature.
[0028] The temperature-controlled circulating liquid can be supplied to a second dispenser 3 via a second mixed-water line 8, such that the temperature-controlled circulating liquid circulates in a circuit as long as the sanitary device 1 is in the circulating operating mode. After switching the sanitary device 1 to the fresh water operating mode, the pump 11 is stopped to keep the circulating liquid from circulating. In fresh water operation mode, the second thermostat 12 is used to dispense only mixed water mixed from the warm water and the cold water via the first dispenser 2. It has to be emphasized that the mixed water can also be routed to a single or joint dispenser, for instance the first dispenser 2 via the first mixed-water line 7 and the circulating liquid via the second mixed-water line 8. In this case, the single or first dispenser 2 can have separate waterways for the mixed water and the circulating liquid, such that the mixed water and the circulating liquid can be routed separately until they are dispensed.
[0029] The sanitary device 1 is characterized in particular by low installation space requirements and low costs.
