Technical Field

The present invention relates to fitting devices, in particular domestic or sanitary fittings and retrofitting methods for retrofitting corresponding fittings.

Background

Various fittings for setting the water temperature are known from the prior art. In the case of conventional thermostatic mixers, a so-called regulating piston is arranged between the hot water inflow and the cold water inflow and is provided on both sides, that is to say towards the hot water inflow and towards the cold water inflow, with a conical or frustoconical closing element, so that it can be moved between the hot water inflow and the cold water inflow. Depending on the positioning, the setting in this way by the adjusting piston results in the mixed water finally delivered from the fitting containing proportionally more cold water or more hot water, that is to say hotter or colder water. Furthermore, the regulating piston is coupled to a temperature sensitive element, so that in case a certain temperature is exceeded, less hot water and more cold water are added to the mixed water.

Disclosure of Invention

The object of the invention is to provide an assembly device which offers increased safety and improved protection against scalding.

This object is achieved with a mounting device of the type mentioned at the outset by the features of claim 1 and claim 13.

Advantageous embodiments and refinements of the invention can be achieved by the measures described in the dependent claims.

The fitting arrangement according to the invention can be used, for example, as a sanitary fitting or as a domestic fitting. It is used to deliver mixed water, where the operator can set the amount and temperature of mixed water to be delivered at the fitting. Initially, the fitting device according to the invention comprises a first inflow line for supplying hot water and a second inflow line for supplying cold water. Two inflow lines, i.e. a first and a second inflow line, lead to the mixing chamber, with the result that hot and cold water can be mixed in the mixing chamber, so that mixed water of a specific temperature can be produced.

In particular, the fitting device according to the invention is characterized in that first shut-off means are provided for controlling and/or shutting off the flow from the first inflow line into the mixing chamber. In this case, the first shut-off device has a temperature-sensitive element to control the flow from the first inflow line as a function of the temperature, in particular to reduce the flow as the temperature increases. In this case, the first shut-off device controls only the flow of the first inflow line, i.e. the inflow of hot water. The assembly device is further characterized in that the second inflow line has an inflow opening to the mixing chamber, which is designed separately from the first shut-off device. The difference from the prior art is therefore that only the hot water inflow is regulated by the first shut-off device.

The mixing chamber accordingly has an outlet line for letting out the mixed water from said fitting arrangement. Furthermore, temperature setting means for setting the temperature of the mixed water is provided so that a user or operator can set the temperature of the mixed water to a desired value. In the assembling device according to the present invention, the temperature setting means may be formed such that:

-the inflow from the first inflow line can only be set, whereas the inflow from the second inflow line is independent of the temperature setting device,

or the inflow from the first inflow line and the inflow from the second inflow line can be set in proportion to one another, in order to obtain a constant volume flow, for example via the outlet line.

In a preferred embodiment, the temperature setting device sets only the inflow from the first inflow line, i.e. only the inflow of hot water.

In any case, the safety can be improved to a certain extent by the fitting device according to the invention. Water inflow pressure variations or temperature variations, such as cold water failures, pressure variations in the cold water line or overall temperature variations, may occur, which may be due to heating water or the use of other heating systems due to regulation problems with the heat pump connected. In this way, an effective and direct scald protection can be achieved, since the hot water supply (first inflow line) is taken only from the measurement of the mixed water and is only regulated. Furthermore, the invention makes it possible to achieve space-saving in existing assembly devices.

Advantageously, in this respect, the setting of the temperature is more uniform and subject to smaller variations, since only hot water is admitted and only one parameter (inflow) of the hot water is regulated. Therefore, changing the amount of cold water supplied is not immediate.

As mentioned above, it is conceivable that in one embodiment of the invention, the temperature setting device is connected in series with the first shut-off device. In this way it is possible for both the first shut-off means and the temperature setting means to be operated independently of each other and for both means to determine the temperature of the water in the outlet line accordingly by means of a series connection. Even if the user sets a very high water temperature by means of the temperature setting means, which is higher than the maximum temperature predetermined by the first shut-off means, the temperature of the mixed water is adjusted to the maximum temperature allowed. This embodiment has the advantage that the user can basically perform the temperature setting in the usual way without the occurrence of: the setting is not substantially changed for different settings of the first cutting device, at least not in the case of exceeding the maximum temperature set at the first cutting device.

However, it is also conceivable for the temperature setting device and the first shut-off device to be coupled to one another. For example, the first inflow line can be shut off by a valve having a closing body which pushes against the seal. The position of the seal relative to the closure body can be set by means of a temperature setting device, i.e. the quantity of water entering the mixing chamber through the first inflow line, i.e. the proportion of the proportional amount of hot water relative to the proportion of the cold water, is predetermined by means of the temperature setting device. In addition, the position of the closure body relative to the seal is also changed, since in the event of an excess of hot water, the first shut-off device of the closure body moves until the latter abuts against the seal and shuts off the hot water through the first water inlet line. This measure has the advantage, in turn, that a particularly compact design can be achieved.

In a preferred embodiment variant of the invention, the first shut-off device comprises an expansion element as a temperature-sensitive element and a piston having a closing body coupled to the expansion element such that the piston is moved when the expansion element expands and/or contracts, wherein the piston is mounted relative to the piston seat seal such that the piston shuts off the flow when the piston and/or the closing body is pushed against the piston seat seal and opens the flow when the piston is moved away from the piston seat seal. If a coupling of the first shut-off device and the temperature setting device is provided, the temperature setting device can predetermine, for example, the position of the piston seat seal, i.e. the piston seat seal moves relative to the piston, with the result that the throughput of water can be set. Advantageously, the use of an expansion element is characterized in that during the conditioning, the expansion element substantially covers the temperature range associated with conventional sanitary and domestic fittings and provides a direct response within a few seconds, i.e. the expansion element can perform a closing operation in time to prevent scalding. In general, the displacement of the slider coupled to the expansion element is proportional to the temperature-induced volume increase.

In order to achieve the most precise possible setting or the most precise possible protection against scalding, it is advantageous to arrange or form the temperature-sensitive element such that it exclusively determines the temperature in the mixing chamber. The mixing chamber contains the actual discharge water which flows out of the fitting through the outlet line, so that the actual temperature of said water is also decisive for scald protection. Basically, pressure changes occur in the cold water line, and the temperature of the supplied cold or warm water also changes. These also affect the temperature of the mixing water. For example, in the case of a constant inflow of hot water at a constant temperature, the temperature of the mixed water may vary because the pressure in the cold water inflow line is changed, or because the temperature of the supplied cold water varies.

In an embodiment variant of the invention, the second inflow line for conducting cold water leads directly and/or without shut-off or other control means to the mixing chamber. As mentioned above, when setting the temperature, only one parameter, in particular the amount of supplied hot water relative to the supplied cold water, is changed.

This adjustment can be simplified overall.

In a development of the invention, the second inflow line, i.e. the cold water supply, can be provided with a constant volume flow regulating device, as a result of which the temperature parameter is regulated solely by the supply of hot water. However, in addition to a simplified temperature setting, this also makes it possible for any pressure changes in the second inflow line (as the external environment is usually present in water lines) to be balanced.

In turn, a piston, which can be moved, for example, via an expansion element, may in turn be mounted such that it moves in the direction of movement, in particular in the direction of the piston seat seal, against an elastic element, such as a spring. In this way it is ensured that in the event of a change in the temperature conditions, the piston not only responds quickly when the temperature rises, but it moves back quickly again in the opposite direction when the temperature falls. If appropriate, the state can be reestablished directly and quickly before the adjustment.

Advantageously, the structural components comprise at least the first cut-off means and the piston as well as the piston seat seal, the expansion element and the temperature sensitive element as well as a restoring element, in particular in the form of an elastic element, for resetting the piston and/or the temperature setting means. The structural part is, if appropriate, in two-part form, wherein the temperature setting device is realized as a separately operable or second part. In this way, it is achieved that no replacement or disassembly of the entire assembly or individual assembly parts is necessary in order to achieve the function according to the invention or, in the case of retrofitting, individual assembly parts. This is very advantageous in particular in connection with retrofitting, maintenance/service or repair. Thus, the entire detachable and mountable structural component according to the invention can advantageously be removed, for example in the event of damage or malfunction, and a new structural component can be inserted in its place. This improves the economic operation of the sanitary fitting according to the invention.

In an exemplary embodiment of the invention, a setting device for setting the flow rate of the mixed water out of the fitting device is advantageously provided. The setting means allow the operator to substantially set the quantity of water per time unit or the quantity of mixed water per time unit delivered by the fitting. In order to keep the quantity of water discharged through the outlet line substantially constant, the setting device can also interact with a constant-volume flow-regulating device or with a second shut-off device for the second inflow line. Thus, for example, if the amount of hot water entering the mixing chamber is reduced, it is essentially necessary to have a large amount of cold water flow into the mixing chamber, so that a constant volume flow can be discharged through the outlet line. However, the inflow of hot water into the mixing chamber can also be reduced in this way, because, for example, the selected maximum temperature associated with the first shut-off device is exceeded and the water flowing out of the mixing chamber is too hot. However, it is also conceivable to indicate to the operator that a subsequent adjustment of the delivered water quantity per time unit has been deliberately omitted and in this case the user immediately notices that less water flows out of the fitting. The operator can thus immediately conclude from this that the temperature setting device on the fitting may be set incorrectly and that, since the maximum temperature has been exceeded, he or she must set the temperature lower and therefore must intervene in a safety regulation device, for example a first cut-off device.

The second shut-off device for the second inflow line can basically be set, for example, in such a way that the flow from the second inflow line is controlled in dependence on the setting device. It is therefore also conceivable that, after the mixing process in the mixing chamber, not the entire flow rate through the assembly device or the mixed water supplied from the mixing chamber, which finally flows out of the assembly device, is regulated overall. Upstream of the mixing chamber there are respective portions in the inflow line. The second shut-off device can also be coupled to a constant volume flow regulating device, if appropriate.

The second shut-off device can be, in particular, a throughflow limiter for setting the minimum flow rate, or a throughflow limiter for setting the minimum flow rate can be used in addition to the second shut-off device. In order to keep the temperature less close to the maximum possible water temperature, a minimum inflow of cold water is required. If only the hot water line is opened, i.e. only or almost all the water from the hot water line (first inflow line), but no or only little water from the cold water line, the maximum possible water temperature is reached, entering the mixing chamber.

Particularly advantageously, a retrofitting method for retrofitting a fitting having a fitting arrangement according to the invention or according to one of the exemplary embodiments described above is characterized in that an existing temperature mixing device is replaced by the retrofitting device, wherein particularly advantageously in a development of the invention the fitting has a structural space (in the form of the structural space of a commercially available mixer shaft) inside and the fitting arrangement can be accommodated completely in said structural space. This measure provides a particular advantage in terms of costs in the first place, since the entire fitting does not have to be replaced. Another advantage is that the manufacturer does not need to completely replace the fitting already available in mass production, but can even retrofit the fitting.

Drawings

Exemplary embodiments of the invention are illustrated in the accompanying drawings and discussed in more detail below, wherein further details and advantages are specified. In detail, in the figures:

figure 1 shows a cross-sectional view of a sanitary fitting according to the invention;

FIG. 2 shows an enlarged view of the mounting device of FIG. 1; and

fig. 3 shows a schematic view of a second sanitary fitting according to the invention.

Detailed Description

Fig. 1 shows a sanitary fitting a with a first inflow line 1 and a second inflow line 2 for the supply of hot and cold water. The inflow 1 via the hot water line can be regulated by a valve device 3, which valve device 3 forms both a temperature setting device 4 and a first cut-off device 5 as scald protection. The device 3 comprises a piston 6 and a piston seat seal 7. The piston seat seal 7 is coupled to a temperature setting stem 8, which temperature setting stem 8 is rotatably mounted for setting purposes. The maximum possible angle of rotation of the temperature setting lever 8 is predetermined by the stop screw 9.

In a preferred second variant of the invention (as shown in fig. 3), the valve device 3 is preferably realized as a separately operable structural component 3. In a second variant, shown in fig. 3, the structural part 3 comprises two units, in particular a temperature setting device 4, as separately operable parts and as the rest of the second unit the above-mentioned parts. In this way it is achieved that the entire structural part 3 can be removed without difficulty, for example during retrofitting or replacement or dismantling, and that a new structural part 3 can be mounted in its place. Thus, it is not necessary to disassemble and reassemble the entire assembly or all of the corresponding individual components. This is very advantageous, in particular in connection with retrofitting, maintenance/service or repair. The entire structural component 3 according to the invention can therefore advantageously be removed, for example in the event of damage or failure, and a new structural component 3 can be inserted in its place.

The structural part 3 can be detached, for example, by loosening the stop screw 9, so that the temperature setting rod 8 with the temperature setting device 4 becomes releasable or can be removed from the sanitary fitting a. The parts of the assembly, such as the shut-off device 5, the piston 6, the piston seat seal 7, the expansion element 11, the spring 13 and the various seals 14, 15, which are subsequently or together with the temperature setting device 4 can then be removed or dismantled together as structural part 3 of the invention. If damage or failure occurs, a new, functional or complete structural component 3 can be installed as a replacement. This saves time and increases the cost effectiveness of the invention.

As an alternative according to the invention, the temperature-setting device 4 can also have a separate valve, by means of which the first inflow line can be set, i.e. in this case the temperature-setting device 4 operates separately from the first shut-off device 5.

The second inflow line 2 (cold water) leads to the mixing chamber 10. The expansion element 11 is connected to the mixing chamber 10, as a result of which the heat of the liquid in the mixing chamber 10 can be transferred to the expansion element 11. The expansion element 11 is in turn coupled to the piston 6. As the temperature of the water in the mixing chamber 10 gradually rises, the expansion element 11 is also heated and expands more and more. The expansion element 11 is selected or set such that if the temperature is too high, it pushes the piston 6 against the piston seat seal 7 and shuts off the inflow of the first inflow line 1 into the mixing chamber 10. The inflow of hot water is thus reduced or prevented, with the result that the temperature of the water in the outlet line 12 arranged downstream of the mixing chamber 10 drops.

During heating, the expansion element 11 expands against the force of the spring 13. During cooling, the spring 13 ensures that the piston 6 is removed from the piston seat seal 7 again quickly.

The seals are indicated by reference numerals 14, 15 in fig. 1.

The volume flow delivered by the fitting a via the outlet line 12 can be controlled via a setting device 16 in the form of a solenoid valve.

Furthermore, a second shut-off device 17 is provided, which second shut-off device 17 is in this case in the form of a rotating sleeve in order to be able to control the volume flow of the cold water.

Fig. 2 shows an enlarged view of a part of the assembly device a. It shows in particular a structural space (B) for accommodating the temperature mixing device inside, in which a corresponding space-saving fitting device a can be retrofitted without the need to replace the remaining housing of the existing sanitary fitting.
