Description

Sanitary fittings and this feeding system

Hair dryers, hand dryers or towel dryers are known, which are operated with warm or hot air. These are either permanently installed as complete units or designed as hand-held devices, each unit comprising an air heater and a blower. If warm or hot air is therefore to be used in a widespread manner, a large number of such complete devices is required, that is to say a considerable amount of construction is required and the individual devices are poorly used.

According to the invention, sanitary fittings are proposed as a hand, bath or towel holder, ring, rod or stand, as a tumble dryer, as a fixed, adjustable or movable, optionally with a hair comb, a hair brush or one Massage brush connected nozzles trained, with a connection nipple in the manner of a flange, screw, bayonet, snap or clamp connection for connection to a stationary hot or hot air source or the outlet of a hot or hot air line system and with an outlet -

Opening or more are provided for the warm or hot air. The invention allows different and several of the fittings mentioned to be connected to the stationary hot or hot air source or to the outlets of a warm or hot air line system.

The connection of the fittings and in particular the replacement of fittings is particularly simple if, according to a feature of the invention, they consist of a base body which can be screwed into the outlet pipe of the air source or of the air duct system and a fitting body which is detachably connected to the base body.

According to a further feature of the invention, each individual fitting can be provided with an adjustable throttling for the air quantity.

The outlets of the stationary hot or hot air source or of the hot or hot air line system can each be provided with shut-off valves or slide valves. According to the invention, provision is preferably made for the individual fittings to be provided with shut-off taps or slides, since these can then be designed as adjustable throttles at the same time the fittings are formed, close.

According to a further feature of the invention, the armature can be provided with a switch mechanism (timer, moisture meter) for actuating the throttling or the shut-off, which is advantageous, for example in the case of dryers, in order to prevent hot or hot air from escaping when the set one Drying time or a desired degree of drying is reached. If the air blowing out of the fitting comes into direct contact with the living body, for example for drying skin or hair or for warm air massage, the fitting can, according to a further feature of the invention, be equipped with a temperature-controlled mixing valve for admixing cold air to warm or hot air be provided.

If, as with hair combs, massage brushes or the like, a special and all-round mobility of the nozzle is required, then according to a further feature of the invention the nozzle is connected to the connection nipple by means of a hose,

As the invention further provides, the fittings according to the invention are used with an air duct system which connects a central warm or hot air generator with outlets for connecting the individual fittings to desired locations and in the desired number. The pipes in this system are made of the flow of heat-resistant ^"material or thermally insulated.

In order to always have hot or hot air available at the outlets in the fittings, the line system is provided according to the invention as a ring line, in which the hot or hot air is kept in circulation.

Where air of a certain temperature is required, cold air is admixed with warm or hot air. For this purpose, in accordance with a further feature of the invention, a line system carrying cold air can be installed parallel to the line system carrying the hot or hot air. Both line systems can be connected to the fittings via mixing valves. This installation is recommended if the extraction is carried out at many or all points in the pipe system temperature-controlled air must be provided. If temperature-controlled air is only required at individual points or in limited areas, according to a further feature of the invention, a mixer or mixer for adding the cold air should be assigned to a part or groups of extraction points. The last arrangement is also recommended if a large number of mixing valves controlled by temperature is to be saved on the individual armatures.

It is provided in the simplest manner according to the invention to design the warm or hot air generator as a heat exchanger which is switched on primarily in the hot water circuit or in the boiler exhaust gas (flue gas) train of a central heating system.

In order to reduce the energy requirement of the system to a minimum, according to a further feature of the invention, single or additional central warm or hot air generators are used to use the secondary heat exchanger of a heat pump and the primary heat exchanger of this heat pump with d from the rooms in where the fittings are installed to heat the exhaust air.

At the inlet to the warm or hot air generator, a feed fan with an air filter is provided, which switches on when the air is drawn from the line system and replenishes the amount of air removed.

The fitting consists of a base body 56, on which a column 57 with a base plate 58 is placed. Towel holders 59 and a towel ring 60 are built into the column. A shelf 61 and a toilet mirror 62 complete the fitting.

A fitting designed as a massage brush is shown in FIG. It consists of the brush 63 which is connected to the connecting nipple 65 by means of a hose 64. The warm air flowing out of the holes 66 serves to support the massage; Likewise, a brush of this type or a comb of a similar design can be formed and used as a hairdryer (see also FIG. 19, parts 111 and 112).

As FIGS. 12 to 18 show, the fittings can also be connected to a piece of furniture, for which purpose the air duct system is then to be led into the piece of furniture. Figures 12 to 15 show work and dining plate combinations which are provided with an air duct system. On one side (Figures 12, 13) or on part of the curve (Figures 14, 15), the plate is cut out in such a way that a strip 71 or 72 results, by means of which hand or tea towels can be hung up to dry. The fittings can be used on the underside of the strips or in a groove on the underside of the strips (FIGS. 16 to 18). The air line 74, which extends into the base cabinet of the furniture 73, is screwed into the base body 75 of the fitting, onto which a nozzle tube 76 is placed. The length of the nozzle tube 76 is provided on the underside with a large number of bores 77, from which the air is blown out, which dries the towels hung over the strips.

3 PI As shown in FIGS. 1 to 18 in examples of multiple possibilities, the fittings can have a very different design, depending on the purpose and type of use, without thereby departing from the scope of the invention.

The invention further relates to the systems in which the fittings according to the invention are used.

Figure 19 shows such a system for a family home. In the basement C there is a heating boiler 81 with a hot water flow 82 and a cold water return 83 from which a hot water heater is fed, which is indicated by the heating element 84. Via a mixing valve 85, which is connected to a temperature indicator 86, hot water of the required temperature is fed from the flow 87 through the finned heat exchanger 88 and via the return 89. The heat exchanger 88 is located at the outlet of a wind boiler 90 which is connected to the hot air supply 91. The hot air flow 91 is the beginning of a hot air ring line, which ends in the hot air return 92 and which in turn opens into the air chamber 90. The hot air in the ring line 91, 92 is kept in constant circulation by a fan 93. A feed blower 94 is provided in order to suck in air via a filter 95 and to reload it into the wind chamber 90 and the ring line 91, 92 when air is removed from the consumption points. A thermostat 96 detects the temperature of the hot air, while a thermostat 97 detects the temperature of the cold air drawn in. Both temperature values are transmitted to a controller 98, by which the mixing valve 85 is actuated such that the temperature of the hot air is kept constant within limits. Various fittings are directly or on the ring line 91/92

C., Ϊ? connected via short intermediate lines. For example, a towel ring 100 (as shown in FIGS. 8, 9) is connected in the toilet located on the ground floor E next to the hand wash basin. In bath B there are two towel holders 101 (as shown in FIGS. 1 to 3) and a towel rail 102 (as shown in FIGS. 4 to 6). These fittings 101 and 102 are each connected to the ring line 91/92 via a valve. These valves are components of a controller 103, which switches the fittings 101 and 102 off from the hot air supply when a preset drying time has expired or a degree of drying of the wipes to be dried, which is determined by a moisture meter, has been reached. Furthermore, in the bathroom B there are air nozzles (as shown in FIG. 7) in rows 104 and 105 around the shower room, which enable showering under the protection of a warm air curtain even in an otherwise cold room. To set an air temperature appropriate to the body, the air nozzles are connected to the ring line 91/92 via a mixer 106, by means of which a quantity of cold air to be set by hand or depending on the temperature is admixed with the hot air. In the kitchen K there are drying strips 107 for towels and tea towels, additional air nozzles 108 for drying the towels and further air nozzles 109, from which drying cupboards for dishes or kitchen linen or dishwashers can be fed, for example. On the upper floor G there is an air nozzle installed as a hand dryer next to a sink. In the basement C, near the swimming pool P and sauna S, a towel rail 110 is installed, as well as a massage brush 111 and a hair comb 112.Massage brush 111 and hair comb 112 are equipped with air jets to provide heat treatment during the massage and hair drying when combing to reach. For this purpose, the massage brush and comb are connected to the connecting nipples via tubes 113, Since a certain body-appropriate temperature must be maintained both during massage and during hair drying, these fittings 111 and 112 are also connected to the ring line 91/92 via a mixer 114.

Figure 20 ^' shows another system for a flat. Since the individual consumer points are closer together, a ring line can be dispensed with. A simple hot air line is sufficient, and a circulation pump is also unnecessary (circulation pump 93 in FIG. 19). The type and design of the fittings largely correspond to those previously described. In the kitchen K there are installed a worktop and dining table combination with a drying bar 120 (corresponding to drying bar 72 in FIGS. 14, 15) and a fixed nozzle 121 for drying hands (corresponding to the nozzle according to FIG. 7). Further fixed nozzles 122, 124 and 126 (corresponding to the nozzle according to FIG. 7) are provided in a cupboard 123 as a plate warmer, in a dishwasher 125 as a dish dryer and in a cupboard 127 as a clothes dryer. An extendable towel holder 128 with towel bars designed as nozzles (similar to the pivotable towel bars according to FIGS. 1 to 3) is arranged under a worktop. A bath towel rod 130 (according to FIG. 4), a drying hood 131 which is movably suspended and used for drying hair, a massage brush 132 and a hair comb 133 (according to FIGS. 11 and

Parts 111 and 112 in Figure 20), two towel holders 134 (according to Figures 1 to 3) and a fixed nozzle 135 (according to Figure 7) as a hand dryer. Installed in the toilet are a towel ring 136 (according to FIGS. 8 and 9) and a skin dryer 137 which, together with an under shower, to be operated alternately, is mounted in a toilet bowl as a combination. If, as in the case of the exemplary embodiment in FIG. 20, the system is restricted to one floor, it is advisable to

OMPI Set up the exchanger also on the floor and guide the hot water circuit up to the heat exchanger on the floor.

In the system shown in FIG. 21, the armatures 140 are only shown schematically, and their number and type can be as desired within the scope of the invention. The fittings are fed from a ring line consisting of the hot air flow 141 and the healing air return 142. A cold air line 143 is installed parallel to the hot air lines 141 and 142 and the fittings 10 or groups of fittings are via temperature-controlled mixing valves connected to the hot air line 141/142 and the cold air line 142 so that warm or hot air of the desired temperature is available on different fittings 140 or groups of fittings. The system is refilled by a compressor 144, which is connected to the line systems via a wind boiler 145. A filter 146 cleans the fresh air drawn in by the compressor 144. The only (as in the exemplary embodiment) or additional hot air generator is the secondary heat exchanger 147 of a heat pump 148, the primary heat exchanger 149 of which is heated by the exhaust air from the rooms in which the fittings 140 are installed, so that the fittings 140 are separated from them. given heat can be partially recovered via the exhaust air by means of the heat pump 148. For this purpose, the rooms in which the fittings 140 are installed are connected to an exhaust air line 150, which discharges the exhaust air from the rooms and feeds the heat exchanger 148 on the primary side to the heat pump 148. In addition to the diverse purposes of the fittings 140, such a system is also suitable for being used as the only or additional space heater. With 151 the circulation pump for the hot air in the ring line supply line 141 and return line 142- is designated.
