Abstract

A shower bath with a spray head (2) above a foot bath (1) or water collecting vessel has the cold water supply line (6) connected to a serpentine coil (10) embedded in the bath. Both the hot (7) and cold water pipes are connected to a thermostatic control valve (5) followed by a manual valve (4). As the shower is used, the cold water supply is gradually preheated by the coil, as warm used water falls on the bath. Less heat is therefore required to raise the temperature of the cold water, and the thermostatic valve adjusts itself accordingly.

Wärmerückgewinnungsanlage an einer Duscheinrichtung Heat recovery system on a shower facility

Stand der TechnikState of the art

Die Erfindung geht aus von einer Wärmerückgewinnungsanlage nach der Gattung des Hauptanspruchs. Es ist schon eine derartige Anlage bekannt (DE-AS 23 04 537), bei welcher der Wärmeübertrager im Boden der -Duschwanne als Verdampfer eines geschlossenen Kältemxttelkreislaufs ausgebildet ist, dessen Verflüssiger ein stückweit oberhalb des Verdampfers in einem Zweig der Kaltwasser-Zuleitung angeordnet ist, der über einen Warmwasserbereiter zum Warmwasseranschluß der Mischbatterie führt. Diese Ausführung ist aufwendig und bedingt einen zusätzlichen Wartungsaufwand für den Warmwasserbereiter.The invention is based on a heat recovery system according to the preamble of the main claim. It's nice such a system known (DE-AS 23 04 537), in which the heat exchanger in the bottom of the shower tray as Evaporator of a closed Kältemxttelkreislaufs is formed, whose condenser is a little way above of the evaporator in a branch of the cold water supply line is arranged, which leads via a water heater to the hot water connection of the mixer. These Execution is complex and requires additional maintenance for the water heater.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Anordnung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß ein zusätzlicher Kältekreislauf und ein Warmwasserbereiter an der Duscheinrichtung entfällt, so daß diese an eine zentrale Warmwasserversorgung oder an eine Fernzapfstelle eines in einem anderen Raum angeordneten Warmwasserbereiters anschließbar ist. Die Wärmerückgewinnung wird mit geringem konstruktiven Aufwand und ohne jeden zusätzlichen Wartungsaufwand erreicht. Sobald nach Beginn des Duschvorgangs vorgewärmtes Wasser aus der.Kaltwasser-Zuleitung zur Mischbatterie gelangt, wird der Zulauf von warmem Wasser selbsttätig durch den Thermostaten in der Mischbatterie oder bei manueller Bedienung durch den Einhebelmischer gedrosselt und dadurch Heizenergie gespart.The arrangement according to the invention with the characterizing features of the main claim has the advantage that an additional cooling circuit and a water heater on the shower facility is omitted, so that this to a central hot water supply or to a Remote tap of a water heater arranged in another room can be connected. The heat recovery is achieved with little construction effort and without any additional maintenance effort. As soon after the start of the shower, preheated water from the cold water supply line reaches the mixer tap, the supply of warm water is automatically controlled by the thermostat in the mixer tap or manually Operation through the single-lever mixer is throttled and heating energy is saved as a result.

Besonders vorteilhaft ist es, wenn der zulaufseitige Anschluß des Wärmeübertragers im Boden der Duschwanne in der Nähe des Ausflusses der Duschwanne angeordnet ist. Der Wärmeübertrager kann zweckmäßig eine in den Boden der Duschwanne integrierte Rohrschlange sein. Diese kann zweckmäßig so ausgebildet und im Boden der Duschwanne geführt sein, daß eine Art Gegenstrom-Effekt auftritt, bei welchem das vorgewärmte Wasser im Bereich der Mitte oder der dem Ausfluß gegenüberliegenden Ecke der Duschwanne aus dem Wärmeübertrager austritt.It is particularly advantageous if the inlet side Connection of the heat exchanger arranged in the bottom of the shower tray near the outlet of the shower tray is. The heat exchanger can expediently be a coil integrated into the floor of the shower tray. These can expediently be designed and guided in the floor of the shower tray that a kind of countercurrent effect occurs, in which the preheated water in the area of the middle or the corner opposite the outlet the shower tray emerges from the heat exchanger.

Beschreibung der ErfindungDescription of the invention

Die Wärmerückgewinnungsanlage ist an einer Duscheinrichtung vorgesehen, die eine Duschwanne 1 und eine Dusche 2 hat j welche über eine Leitung 3 und ein Absperrventil 4 mit dem Ausgang einer thermostatischen Mischbatterie 5 verbunden ist. Diese ist an eine Kaltwasser-Zuleitung 6 und an eine Warmwasser-Zuleitung 7 angeschlossen. Die Kaltwasser-Zuleitung 6 führt über einen Wärmeübertrager 1O3 der im Boden 11 der Duschwanne 1 angeordnet ist. Der Wärmeübertrager 10 ist als Rohrschlange ausgebildet, die in den Boden 11 der Duschwanne integiert ist. Der zulaufseitige Anschluß des Wärmeübertragers 10 ist in der Nähe des Ausflusses 12 der Duschwanne 1 angeordnet, während der ablaufseitige Anschluß des Wärmeübertragers 10 an einer näher an der Dusche 2 liegenden Längsseite 13 der Duschwanne 1 vorgesehen ist. Die Rohrschlange des Wärmeübertragers 10 ist so geführt, daß ein Gegenstrom-Effekt auftritt, bei welcher das vorgewärmte Wasser in dem Bereich der Duschwanne 1 aus dem Wärmeübertrager 10 austritt, in welchem in der Regel das verbrauchte Duschwasser die höchsten Temperaturen aufweist .The heat recovery system is provided on a shower device which has a shower tray 1 and a shower 2 which is connected to the outlet of a thermostatic mixer tap 5 via a line 3 and a shut-off valve 4. This is connected to a cold water supply line 6 and a hot water supply line 7. The cold water supply line 6 leads via a heat exchanger 1O 3 which is arranged in the floor 11 of the shower tray 1. The heat exchanger 10 is designed as a coil which is integrated into the floor 11 of the shower tray. The inlet-side connection of the heat exchanger 10 is arranged in the vicinity of the outlet 12 of the shower tray 1, while the outlet-side connection of the heat exchanger 10 is provided on a longitudinal side 13 of the shower tray 1 closer to the shower 2. The coil of the heat exchanger 10 is guided in such a way that a countercurrent effect occurs in which the preheated water emerges from the heat exchanger 10 in the area of the shower tray 1, in which the used shower water usually has the highest temperatures.

Sobald nach Beginn des Duschvorganges der Mischbatterie 5 vorgewärmtes Wasser aus der Kaltwasser-Zuleitung 6 zuläuft, wird der Zulauf von warmem Wasser aus der Leitung 7 durch den Thermostaten in der Mischbatterie 5As soon as the mixer tap 5 has preheated water from the cold water supply line 6 runs in, the supply of warm water from the line 7 through the thermostat in the mixer 5
