Definitions
- the invention relates to a fitting device, in particular a household or sanitary fitting, and a retrofit method for retrofitting the corresponding fitting.
- a so-called regulating piston is connected between the hot water and the cold water inlet, the double-sided, i. for hot water and cold water inlet, is provided with conical or frusto-conical closure elements and thus can be moved back and forth between the hot water inlet and the cold water inlet.
- the regulating piston adjusts in this way whether the mixed water that is finally discharged from the fitting contains proportionally more cold water or more hot water, ie is warmer or colder.
- the regulating piston is coupled to a temperature-sensitive element, so that when a certain temperature is exceeded, less hot water and, instead, more cold water is added to the mixing water.
- the object of the invention is a fitting device
- the fitting device according to the invention can be used for example as a sanitary fitting or household fitting. It serves to deliver mixed water, with an operator the Quantity and temperature of the mixed water to be delivered to the
- the fitting device comprises a first supply line for the supply of
- Hot water and a second supply line for supplying cold water Both supply lines, so the 1st and the 2nd
- Supply line open into a mixing chamber, so that hot and cold water can mix in it to produce mixed water of a certain temperature can.
- the invention is characterized by:
- Armaturvorraum characterized in that a first shut-off device for controlling or shutting off the flow from the 1.
- Supply line is provided in the mixing chamber.
- the first shut-off device on a temperature-sensitive element to the flow from the first supply line in dependence on the
- shut-off device controls only the flow of the first supply line, so the hot water supply. It is further distinguished by the fact that the second supply line has an inlet to the mixing chamber, which is formed independently of the first shut-off device. In contrast to the prior art is thus only the
- the mixing chamber in turn, accordingly has an outlet line for draining the mixed water from the fitting device.
- a temperature adjusting device for adjusting the temperature of the mixed water is provided so that the user or the operator can set the temperature of the mixed water to a desired value.
- this temperature adjustment device can be designed such that it:
- Supply line in relation to each other can set to for example, a constant volume flow over the
- the inflow from FIG. 1 will only be achieved by the temperature adjusting device.
- the safety can be increased in any case in particular. It can, for example, in the water flow to pressure fluctuations or temperature fluctuations, for example in a
- Heat supply system In this way, an effective and direct scalding protection can be achieved, since solely on the basis of a measurement on the mixed water on the hot water supply (1st supply line) is accessed and only the hot water supply is controlled.
- the invention also allows a space-saving implementation within an existing fitting device.
- the setting of the temperature is more uniform and subject to lower fluctuations, since only the hot water is accessed and only one parameter (the inflow amount) of the hot water is controlled.
- this is not necessarily accompanied by the fact that the amount of supplied cold water is also changed.
- the first supply line can be shut off via a valve which has a closure body which presses against a seal.
- the position of the seal with respect to the closure body can over the
- Temperature setting be adjusted by the temperature setting device is specified as how much water passes through the first supply line into the mixing chamber, that is, how high the proportion of hot water relative to the
- Closing body moves until it comes with the seal in the stop and the hot water supply on the first
- the first shut-off device comprises an expansion element as
- Temperature adjustment for example, the position of the piston seat seal pretend, i. the piston seat seal is displaced with respect to the piston so that the flow rate of water can be adjusted.
- the expansion element can shut off in time to prevent scalding can. As a rule, this is the displacement of the coupled to the expansion element
- the temperature-sensitive element In order to enable as precise a setting as possible or a scalding protection that is as precise as possible, it is advantageous for the temperature-sensitive element to be arranged or designed such that it exclusively determines the temperature in the mixing chamber.
- the actual output water which passes through the output line from the valve, is included, so that its actual temperature also
- the temperature of the mixed water may therefore vary because the pressure in the cold water supply line changes or because the temperature of the supplied cold water varies.
- the 2 opens.
- Inlet pipe for directing cold water directly or without
- Constant volume flow control must be provided so that only the temperature parameter on the supplied amount of hot water is controlled. In addition to a simplified temperature setting but this also allows any pressure fluctuations in the 2nd supply line, which can generally come about in the water lines due to external circumstances, can be compensated.
- the piston in turn, which can be displaced, for example, via the expansion element, can in turn be mounted in such a way that it moves in a direction of movement, in particular in the direction of movement
- Temperature conditions not only respond quickly when the temperature increases, but also quickly at a temperature
- a structural unit comprises at least the first shut-off device and the piston and the piston-seat seal and the expansion element and the temperature-sensitive element and a return element designed in particular as the elastic element for returning the piston and / or the
- Invention provided an adjustment for adjusting the flow of the mixed water from the fitting device. With this an operator can basically set how much water per unit of time or how much mixed water per unit time is discharged from the valve. In order for the amount of water discharged via the outlet line to remain basically constant, this setting device can also be equipped with a constant volume flow control or with a second flow control
- Outlet line can flow out. Such a reduction of the hot water flow into the mixing chamber but can also be caused by the fact that, for example, in the
- Shut-off device may be provided to the flow from the 2nd supply line, for example, depending on the
- the second shut-off device can in particular as
- Flow restrictor be designed to set a minimum flow or be used in addition to the 2nd shut-off. A minimum inflow of cold water is needed so that the temperature is not too close to the maximum possible water temperature. The maximum possible
- Hot water pipe is open, so in the mixing chamber
- Hot water supply (1st supply line), but not or very little from the cold water line passes.
- the fitting has a space in the interior (in the form of a space of a commercial mixing shaft) and the fitting device can be completely accommodated in this space.
- This measure represents a special cost advantage because I have to replace the entire valve.
- manufacturers already in series production existing valves are not complete
- FIG. 1 shows a sectional view of a sanitary fitting according to the
- Fig. 3 a schematic representation of a second
- Figure 1 shows a sanitary fitting A, which has a first and a second supply line 1, 2 for supplying hot and cold water.
- the inlet 1 via the hot water pipe can be controlled by a valve device 3, which forms on the one hand the temperature setting device 4 and on the other hand the first shut-off device 5 as a scalding protection.
- This device 3 comprises a piston 6 and a piston seat seal 7.
- the piston seat seal 7 couples to the temperature setting lever 8, which is rotatably mounted for adjustment.
- valve device 3 in a preferred second variant of the invention (as shown in Figure 3) realized as a separately manageable unit 3.
- the assembly 3 comprises two units, namely the temperature adjustment 4 as a separately manageable piece and as a second unit the remaining, above components. This ensures that, for example, when retrofitting or replacement or disassembly, the entire unit 3 dismantled without much effort and a new unit 3 can be re-assembled. As a result, it is not necessary to disassemble and reassemble the entire valve or all corresponding individual components. This is just from the point of view
- Impairment, and a new unit 3 are used again.
- the assembly 3 can be dismantled by a stopper screw 9 is released, so that the
- Temperature setting lever 8 with the temperature setting 4 is solvable or can be removed from a sanitary fitting A. Subsequently or together with the temperature adjusting device 4, components of the fitting can then be used together
- Dehnscherlement 11, spring 13 and various seals 14, 15 are removed or removed as a unit 3 according to the invention.
- a new, functioning or intact structural unit 3 can then be reassembled. This saves time and improves the
- Temperature adjustment device 4 have a separate valve with which the first supply line can be adjusted, i. in this case the works
- the second supply line 2 (cold water) opens into a
- the mixing chamber 10 With the mixing chamber 10 is a Expansion element 11 in conjunction, so that the heat of the liquid in the mixing chamber 10 can be transferred to the expansion element 11.
- the expansion element 11 in turn couples to the piston 6. With increasing increase in the temperature of the water in the mixing chamber 10 and the expansion element 11 is heated and expands more and more.
- the expansion element 11 is selected or adjusted so that when the temperature is too high, it pushes the piston 6 against the piston seat seal 7 and shuts off the inlet of the first supply line 1 into the mixing chamber 10. The supply of hot water is thus reduced or prevented, so that the water temperature in the discharge line 12, which is connected downstream of the mixing chamber 10, decreases.
- the expansion element 11 expands when heated against the force of a spring 13. Upon cooling, the spring 13 ensures that the piston 6 is quickly removed again from the piston seat seal 7.
- Valve A is discharged, can be controlled via the adjustment device 16 in the form of a solenoid valve.
