and FIG. 7 shows a side view of the shower head and of the end region of the outlet body from FIG. 6, wherein the shower head is in a working position in which the shower head is spaced apart from the outlet body.Identical or functionally equivalent elements are denoted by the same reference numerals in all figures.A fitting, which is illustrated in FIGS. 1 to 7 and is denoted as a whole by 100, and is provided for use on a basin, in particular on a sink, comprises a base body 102, which can be fixed to a suitable underlying surface, for example on a sink or a countertop, and an outlet body 104 carried by the base body 102.As best seen in FIG. 2, the outlet body 104 is preferably held on the base body 102 such that it can be pivoted about a pivot axis 106.The pivot axis 106 is preferably aligned substantially vertically in the assembled state of the fitting 100.The outlet body 104 preferably comprises a base section 108 adjoining the base body 102 and an end section 110 facing away from the base body 102.When the outlet body 104 is pivotable about a pivot axis 106, the end portion 110 preferably extends away from the pivot axis 106 in a substantially radial direction.The end portion 110 of the outlet body 104 is provided, preferably at its lower side, with a hot water outlet 112 for the discharge of hot water.As best seen in FIG. 5, the hot water outlet 112 may specifically include a Perlator® or pearlescent heater 114, a connector 116, and an intermediate piece 118 connecting the connector 116 to the Perlator® or pearlescent heater 114.The outlet body 104 comprises a, preferably substantially tubular, outer shell 120 which is penetrated in the end section 110 of the outlet body 104 by the hot water outlet 112, in particular by the Perlator® or pearlescent radiator 114.The intermediate piece 118 and the connecting piece 116 are preferably arranged in an interior space 122 of the outer casing 120.A hot water line 124 is connected to the connection piece 116, which extends from the hot water outlet 112 through the interior space 122 of the outlet body 104 and through the base body 102 into an exterior space 126 of the fitting 100 as far as a hot water outlet 128 of a hot water source 130, for example in the form of a hot water boiler 132.The hot water source 130 serves for providing hot water having a temperature of at least 95° C., particularly preferably of at least 97° C.In particular, it can also be provided that the hot water source 130 provides hot hot water boiling at its hot water outlet 128, which hot water can also contain a gaseous phase in addition to a liquid phase.The hot water source 130 is preferably provided with a controller 133 for setting a desired hot water starting temperature.The hot water source 130 further comprises a cold water inlet 134 which is connected via a cold water line 137 to an outlet of a hot water control valve 136.The hot water control valve 136 is preferably disposed on the base body 102 of the armature 100.The hot water control valve 136 may have a safety catch element 138, by which an actuating element 140 of the hot water control valve 136 is latched in a closed position of the hot water control valve 136.After the safety latching element 138 has been unlocked, the actuating element 140 can be transferred from the closed position into an open position in which the passage of water through the hot water control valve 136 is enabled. Thus, the safety catch element 138 serves in particular as a child safety device which prevents unintentional dispensing of hot water through the hot water outlet 112 of the fitting 100.Connected to an inlet of the hot water control valve 136 is one end of a cold water supply line 142 which leads out of the base body 102 of the fitting 100 into the outer space 126 thereof to a cold water source (not shown).A further end of the cold water feed line 142, which preferably branches within the base body 102, is connected to a cold water inlet of a mixing valve 144.The mixing valve is arranged on the base body 102 of the fitting 100.The mixing valve 144 and the hot water control valve 136 are disposed on opposite sides of the base body 102. In particular, it may be provided that the mixing valve 144 and the hot water control valve 136 are diametrically opposed to each other on the base body 102.A hot water feed line 146 is connected to a hot water inlet of the mixing valve 144, which leads out of the base body 102 into the outer space 126 of the fitting 100 and there to a hot water source (not shown).A mixed water line 148 (shown in FIGS. 4 and 5 ) is connected to a mixed water outlet of the mixing valve 144.The mixed water line 148 extends from the mixing valve 144 through a part of the base body 102 and the interior space 122 of the outer casing 120 of the outlet body 104 as far as a mixed water outlet 150 which is arranged on a shower head 152 of the fitting 100 (see FIGS. 5 and 6 ).The shower head 152 comprises a, for example substantially hollow cylindrical, casing 154.The mixed water outlet 150 comprises, for example, a Perlator® or pearlescent radiator 156, which extends through the casing 154 into the outer space 126 of the fitting 100, and a water guide element 160 arranged in an inner space 158 of the casing 154, which comprises a water guide channel 162 and a receptacle 164 for a connection piece 166 at the shower-head-side end of the mixed water line 148.The mixed water from the mixed water line 148 passes through the water guide channel 162 to the Perlator® or pearlescent radiator 156, from where it is discharged into the outer space 126 of the fitting 100.The mixed water line 148 can comprise in particular a flexible shower hose 168.The mixed water line 148 can comprise in particular a water-conducting hose made of a plastic material, preferably made of a silicone material, and / or a sheathing made of a metallic material, for example made of a stainless steel material, and / or made of a plastic material, in particular made of a polyamide material, particularly preferably made of a plastic material fabric, in particular made of a polyamide fabric.The Perlator® or pearlescent radiator 156 and / or the water guide element 160 preferably comprise a plastic material, for example a polyoxymethylene (POM) material.The volume flow and the temperature of the mixed water flowing through the mixed water line 148 can be adjusted by means of the mixing valve 144.For example, the mixing valve 144 can comprise an actuating lever 170 which is movable in two degrees of freedom, for example by rotation about a pivot axis 172 (preferably horizontally oriented in the mounted state of the fitting 100) and by tilting relative to the pivot axis 172.In this case, one of the degrees of freedom of movement of the actuating lever 170, for example the rotation, determines the ratio in which the hot water from the hot water inlet of the mixing valve 144 and the cold water from the cold water inlet of the mixing valve 144 are mixed with one another and therefore the temperature of the mixed water leaving the mixed water outlet of the mixing valve 144, while the respective other degree of freedom of movement of the actuating lever 170, for example the tilting, controls the volume flow through the mixed water outlet of the mixing valve 144.The hot water line 124 is formed from a material which is stable at the temperature of the hot water during operation of the fitting 100, that is to say for example at a temperature of at least 95° C.In particular, it can be provided that the hot water line 124 comprises a polytetrafluoroethylene (PTFE) material.The hot water line 124 and the mixed water line 148 are arranged at least in sections within the outer casing 120 of the outlet body 104 of the fitting 100.The hot water line 124 is separated from the outer shell 120 of the spout body 104 by an insulation layer 174.The mixed water line 148 is preferably separated at least in sections from the hot water line 124 and / or from the outer casing 120 of the outlet body 104 by an insulation layer 174.Such an insulation layer 174 prevents the mixed water in the mixed water line 148 from being heated by the hot water in the hot water line 124 and / or prevents the outer casing 120 of the outlet body 104 from being heated by the hot water in the hot water line 124 and / or by warm mixed water in the mixed water line 148. This prevents an operator touching the outer casing 120 of the outlet body 104 from suffering an unpleasant temperature sensation or even scalding.Spacer elements made of a heat-insulating material, in particular made of a plastic material, can furthermore be arranged in the interior 120 of the outer casing 120 of the outlet body 104, by means of which spacer elements the hot water line 124 and / or the mixed water line 148 are held at a distance from the outer casing 120 of the outlet body 104.Due to the heat-insulating effect of such spacer elements and / or the insulation layer 174, the outer casing 120 of the outlet body 104 can be formed from a material with good heat conductivity, for example from a metallic material, in particular from brass or from a stainless steel material.In the shower head 152, too, the water guide channel 162 which conducts the mixed water (if appropriate warm) is held at a distance from the casing 154 of the shower head 152 by spacer elements 176 provided on the water guide element 160 and / or by an insulation layer 178.The jacket 154 of the shower head 142 can therefore likewise be formed from a material with good thermal conductivity, in particular from a metallic material, for example from a stainless steel material or from brass.The insulation layer 178 in the shower head 152 and / or the insulation layer 174 in the interior 122 of the outer casing 120 of the outlet body 104 can be formed in particular from air and / or from a heat-insulating material, in particular from a plastic material, for example from a polyurethane material.As can best be seen from a comparison of FIGS. 5 and 6, in the rest position of the shower head 152 shown in FIG. 5, an end region 180 of the shower head 152 on the outlet body side is accommodated in a receptacle 182 on the end of the outlet body 104 on the shower head side.The end region 180 of the shower head 152 can be held in the receptacle 182 in particular by frictional engagement and / or by latching, in order to prevent unintentional release of the shower head 152 from the rest position on the outlet body 104.From the rest position on the outlet body 104 shown in FIG. 5, the shower head 152 with the mixed water outlet 150 arranged thereon can be brought into an operating position shown by way of example in FIG. 6 by the outlet-body-side end region 180 of the shower head 152 being pulled out of the receptacle 182 of the outlet body 104.The extraction of the shower head 152 from the receptacle 182 of the outlet body 104 is made possible by the flexibility of the mixed water line 148.In the working position illustrated in FIG. 6, the shower head 152 is spaced apart from the outlet body 104 by the distance d.Preferably, the pull-out length d of the mixed water line 148, by which the mixed water line 148 can be pulled out of the outlet body 104, is at least approximately 30 cm, particularly preferably at least approximately 50 cm.The above-described fitting 100 with the cold water supply line 142, the hot water supply line 146, the cold water line 137 and the hot water line 124, and the hot water source 130, for example in the form of a hot water boiler 132, together form a hot water dispensing system 184 which is additionally capable of dispensing mixed water through a shower head 152 which can be pulled out of an outlet body 104 of the fitting 100.During the assembly of the hot water dispensing system 184, the base body 102 of the fitting 100 is fixed to a work plate or sink (not shown) or to a washbasin by means of a fixing device 186 which is known per se.The cold water supply pipe 142 is connected to the cold water source (not shown) provided on the site, and the hot water supply pipe 146 is connected to the hot water source (not shown) also provided on the site.The cold water line 137 is connected to the cold water inlet 134 of the hot water source 130, and the hot water line 124 is connected to the hot water outlet 128 of the hot water source 130.The hot water source 130 is connected to the electrical grid (not shown) provided on the site.The desired outlet temperature of the hot water at the hot water outlet 128 is set by means of the controller 133.Thus, the hot water supply system 184 is operable.By actuating the actuating element 140 of the hot water control valve 136, optionally after unlatching of the securing latching element 138, hot water can be drawn out of the hot water outlet 112 in the end section 110 of the outlet body 104 of the fitting 100.By operating the operating lever 170 of the mixing valve 144, mixed water having the desired temperature can be drawn out through the mixed water outlet 150 of the shower head 152.The shower head 152 is movable from its rest position shown in FIG. 5 into the working position shown by way of example in FIGS. 6 and 7, in which the shower head 152 is spaced apart from the outlet body 104 of the fitting 100 and is freely movable relative to the outlet body 104 (within the limits predetermined by the extension length of the mixed water line 148).As a result, the mixed water can be removed in any desired position relative to the outlet body 104 of the fitting 100.In this way, in particular large containers, for example buckets, pots and vases, can be filled with the mixed water.In addition, in this way, objects and devices, for example a sink or other constituents of a sink, in particular a drip surface, can be cleaned by means of the mixed water.The space within which the mixed water outlet 150 can be used is thereby significantly enlarged.
