The oxygen-containing mixture flows from the evaporator bath (10) via one or more steam conduits (18) through the heater and emerges into the sauna room (33) at the upper side of the heater (1).

Description

Saunaofen umschaltbar von Trockensauna-Betrieb auf Dampfsauna-Betreib, bestehend aus einem Mantel aus hitzebeständigem Werkstoff, der in einem Gestell gehalten ist, mit einem an der Oberseite angeordneten luftdurchlässigen Korb zur Aufnahme von Steinen sowie mit einer Heizeinrichtung, wobei am offenen Boden des Ofens zugeführte Zuluft bei Saunabetrieb durch den Ofen hindurchströmt und an der Oberseite in den Saunaraum austreten kann, sowie mit einer unterhalb des Ofens mit Abstand zu dessen Boden angeordneten Verdampferwanne zur Aufnahme von Flüssigkeit und einer innerhalb der Verdampferwanne vorgesehen Heizvorrichtung.Sauna heater switchable from dry sauna operation to steam sauna operation, consisting of a jacket made of heat-resistant material, which is held in a frame, with an air-permeable basket arranged on the top for holding stones and with a heating device, with the heater being fed to the open floor In the case of sauna operation, supply air flows through the heater and can exit into the sauna room at the top, as well as with an evaporator trough arranged below the heater at a distance from the bottom thereof for receiving liquid and a heating device provided within the evaporator trough.

Aus der DE-A- 31 41 820 ist ein Saunaofen bekannt, bei dem der Korb zur Aufnahme von Steinen von dem Ofengestell entfernt und durch einen Wasserbehälter ersetzt werden kann, in dem umgeben von unten offenen Taschen Heizstäbe hineinragen. Die Taschen überragen die Wasseroberfläche und ihre oberen Öffnungen können mittels gemeinsam betätigbarer Klappen geschlossen und mehr oder weniger geöffnet werden. Dadurch kann die Wärme der Heizstäbe entweder die hindurchströmende Luft für den Saunaraum oder das Wasser erwärmen, was zu einer höheren Luftfeuchtigkeit im Saunaraum führt.From DE-A-31 41 820 a sauna heater is known in which the basket for holding stones can be removed from the heater frame and replaced by a water container in which heating rods protrude surrounded by pockets open from below. The pockets protrude above the water surface and their upper openings can be closed and opened more or less by means of flaps that can be operated together. As a result, the heat from the heating elements can either heat the air flowing through it for the sauna room or the water, which leads to higher air humidity in the sauna room leads.

Abgesehen von der Tatsache, daß eine Dampferzeugung auf diese Weise sehr viel Energie benötigt und die Dampfmenge und die Dampftemperatur schwierig zu regulieren ist, muß auch das Auswechseln des Steinkorbes gegen den Wasserbehälter von Hand als umständlich angesehen werden, um von Trockensaunabetrieb auf Dampfsaunabetrieb überzugehen. Desweiteren tritt das Problem auf, daß bei Erreichen der erforderlichen Saunatemperatur die Lufterwärmung abgeschaltet wird und danach der Dampf sich unmittelbar zum Boden bewegt.In addition to the fact that steam generation in this way requires a lot of energy and the amount and temperature of steam is difficult to regulate, the replacement of the stone basket with the water tank by hand must be considered cumbersome to switch from dry sauna operation to steam sauna operation. Furthermore, the problem arises that when the required sauna temperature is reached, the air heating is switched off and the steam then moves directly to the floor.

Fehlende Frischluft sowie die Gefahr der Bakterienbildung und der Schimmelbildung im unteren Bereich der Saunakabine lassen sich dadurch auf Dauer nicht vermeiden.A lack of fresh air and the risk of bacteria and mold in the lower area of the sauna cabin cannot be avoided in the long term.

Sauerstoff in ausreichender Menge und die Möglichkeit der Verwendung reinen Dampfes zur Inhalation, sowie zur Aufnahme über die Poren der Haut und der Atemwege, sind bei dem bekannten Saunaofen nicht gegeben. Bei der bekannten Ausführungsform können auch Verbrühungen oder Verbrennungen durch überkochendes Wasser auftreten.A sufficient amount of oxygen and the possibility of using pure steam for inhalation, as well as for absorption via the pores of the skin and the respiratory tract, are not given in the known sauna heater. In the known embodiment, scalding or burns due to boiling water can also occur.

Einer sauerstoffhaltiges Mischluftklima ist nicht erreichbar.An oxygen-containing mixed air climate cannot be achieved.

Aus der DE-A- 34 04 892, die dem Oberbegriff des Anspruchs 1 Zugrundeliest, ist ein Saunaofen bekannt, mit dem eine Umstellung von Trockensaunabetrieb auf Dampfsaunabetrieb und umgekehrt möglich ist. Jedoch ist eine sichere und zuverlässige Regelung der Dampfmenge, Dampftemperatur und Lufttemperatur nicht gewährleistet.From DE-A-34 04 892, which is based on the preamble of claim 1, a sauna heater is known with which a conversion from dry sauna operation to steam sauna operation and vice versa is possible. However, safe and reliable control of the amount of steam, steam temperature and air temperature is not guaranteed.

Bei diesem bekannten Saunaofen ist unterhalb desselben mit Abstand zu dessen Boden eine Verdampferwanne zur Aufnahme von Flüssigkeit vorgesehen ist, innerhalb der eine Heizvorrichtung installiert ist. Dabei ist die Heizvorrichtung bei vorbestimmbaren Temperaturwerten der regelbaren Heizeinrichtung des Ofens ein- bzw. ausschaltbar.In this known sauna heater there is an evaporator trough below it at a distance from the bottom for receiving liquid is provided within which a heating device is installed. The heating device can be switched on or off at predeterminable temperature values of the controllable heating device of the furnace.

Der erzeugte Wasserdampf wird mit der frischen Zuluft über die heißen Heizstäbe und die Steine geführt. Eine derartige Anordnung ist mit einer Reihe von Nachteilen verbunden. Der Zusatz ätherischer Öle bzw. Essenzen für medizinische Anwendung ist problematisch, weil diese Dämpfe heiße Zonen durchdringen, die diese Stoffe verändern bzw. ihre Wirksamkeit beeinträchtigen. Außerdem erzeugt die große freiliegende Wasseroberfläche der oben offenen Verdampferwanne bei Nichtgebrauch der Sauna ständig feuchte Luft.The steam generated is led with the fresh supply air over the hot heating elements and the stones. Such an arrangement has a number of disadvantages. The addition of essential oils or essences for medical use is problematic because these vapors penetrate hot zones that change these substances or impair their effectiveness. In addition, the large exposed water surface of the open top evaporator pan creates constantly moist air when the sauna is not in use.

Die flache noch oben offene Verdampferwanne unter dem Ofen hat auch den Nachteil, daß sich Staub ablagern kann.The flat evaporator pan under the oven, which is still open at the top, also has the disadvantage that dust can accumulate.

Der Erfindung liegt die Aufgabe zugrunde, einen Saunaofen zu schaffen, mit dem in einfacher und bequemer Weise eine Umstellung von Trockensaunabetrieb auf Dampfsaunabetrieb und umgekehrt möglich ist. Darüber hinaus soll eine sichere und zuverlässige Regelung der Dampfmenge, Dampftemperatur und Lufttemperatur möglich sein. Darüber hinaus liegt der Erfindung die medizinisch sehr wichtige Aufgabe zugrunde, keinen Tröpfchennebel, sondern Dampf in Form gasförmiger Molekule sehr kleiner Abmessungen zu erzeugen, welche um ein Vielfaches kleiner sind als der feinste Nebel.The invention has for its object to provide a sauna heater with which a switch from dry sauna operation to steam sauna operation and vice versa is possible in a simple and convenient manner. In addition, a safe and reliable control of the amount of steam, steam temperature and air temperature should be possible. In addition, the invention is based on the medically very important task of not generating droplet mist, but steam in the form of gaseous molecules of very small dimensions, which are many times smaller than the finest mist.

Dies wird erfindungsgemäß dadurch erreicht, daß sich von der Verdampferwanne bis zum Dampfaustritt an der Oberseite des Ofens ein oder mehrere Dampfleitrohre erstrecken.This is achieved according to the invention in that one or more steam guide tubes extend from the evaporator trough to the steam outlet on the top of the furnace.

Durch die Ausbildung des Saunaofens in der erfindungsgemäßen Weise strömt die frische Zuluft beim Dampfbadbetrieb über eine Öffnung in die Verdampferwanne. Über das in die Verdampferwanne mündende Dampfleitrohr wird der Dampf durch den Ofen hindurch geführt und tritt an der Oberseite des Saunaofens in den Saunaraum aus.By designing the sauna heater in the manner according to the invention, the fresh supply air flows through an opening into the evaporator trough during steam bath operation. The steam is led through the heater via the steam guide pipe leading into the evaporator pan and exits into the sauna room at the top of the heater.

Auf diese Weise wird eine Berührung des Dampfes mit den Heizstäben für die Lufterwärmung vermieden. Eine längere Lebensdauer dieser Heizstäbe wird somit erreicht. Beim Umschalten von Saunabetrieb auf Biodampfbadbetrieb muß nicht mehr jedesmal das Wasser abgelassen werden. Eine Verdampfung während des Saunabetriebes ist durch die erfindungsmäßige Konstruktion nicht mehr möglich.In this way, contact of the steam with the heating elements for air heating is avoided. A longer service life of these heating elements is thus achieved. When switching from sauna operation to bio steam bath operation, the water no longer has to be drained every time. Evaporation during sauna operation is no longer possible due to the construction according to the invention.

Im einzelnen ist die Erfindung so getroffen, daß die Verdampferwanne bis auf die Öffnungen für die Zuluft und die Anschlußöffnungen für das Dampfleitrohr allseitig geschlossen ist. In einer vorteilhaften Ausführungsform kann die Verdampferwanne einen dem Boden des Ofens zugekehrten Deckel aufweisen, in dem die Öffnungen für die frische Zuluft angeordnet sind. Auf diese Weise befindet sich die Flüssigkeit zur Dampferzeugung in einem geschlossenen Behälter und kann weder verschmutzen noch ungewollt verdunsten.In particular, the invention is such that the evaporator trough is closed on all sides except for the openings for the supply air and the connection openings for the steam conduit. In an advantageous embodiment, the evaporator pan can have a cover facing the bottom of the oven, in which the openings for the fresh supply air are arranged. In this way, the liquid for steam generation is in a closed container and can neither contaminate nor evaporate unintentionally.

Ferner ist in zweckmäßiger Weise am oberen Ende des Dampfleitrohres im Bereich des Dampfaustritts ein Füllbehälter zum Nachfüllen von Flüssigkeit in die Verdampferwanne vorgesehen, der bei gefüllter Verdampferwanne als Dampfaustrittöffnung dient.Furthermore, a filling container for refilling liquid into the evaporator trough is expediently provided at the upper end of the steam guide tube in the region of the steam outlet and serves as a steam outlet opening when the evaporator trough is full.

In diesem Behälter kann auf einem Distanzhalter das Sieb für den Dampfaustritt eingesetzt sein, daß zugleich als Ablage für Heilkräuter oder Heilkräuter in Essenzform dienen kann.In this container, the sieve for the steam outlet can be inserted on a spacer that can also serve as a tray for medicinal herbs or medicinal herbs in essence form.

Der austretende Dampf strömt somit als Mischluft in den Saunaraum gleichmäßig verteilt ein und hat somit eine hervorragende medizinische Wirkung.
Durch den erfindungsgemäßen Saunaofen wird sauerstoffhaltige Mischluft in feinster Verteilung aus der Verdampferwanne bis zum oberen Ende des Ofens zur Austrittsöffnung geleitet, ohne daß diese Dämpfe heiße Zonen durchdringen, und die Zusätze aus ätherischen Ölen, Essenzen oder reinen Heilkräutern in ihrer Wirksamkeit beeinträchtigt werden können.
The escaping steam flows into the sauna room as mixed air and has an excellent medicinal effect.
Through the sauna heater according to the invention, oxygen-containing mixed air is distributed in the finest distribution from the evaporator trough to the upper end of the heater to the outlet opening, without these vapors penetrating hot zones and the effectiveness of essential oils, essences or pure medicinal herbs being impaired.

Im Bereich der Verdampferwanne, deren Flüssigkeit auf eine Temperatur von etwa 100 Grad Celsius erwärmt wird, ist eine Bakterienbildung nicht möglich, da dieselben bereits ab einer Temperatur von etwa 60 Grad Celcius vernichtet werden. Die einströmende Frischluft in die Verdampferwanne durch die Zuluftöffnungen wie auch die angesaugte Umluft aus der Kabine werden somit neutralisiert. Außerdem wird der Wasserverbrauch verringert.Bacteria cannot form in the area of the evaporator trough, the liquid of which is heated to a temperature of around 100 degrees Celsius, since they are destroyed at a temperature of around 60 degrees Celsius. The fresh air flowing into the evaporator pan through the supply air openings and the intake air from the cabin are thus neutralized. Water consumption is also reduced.

Bei dem erfindungsgemäßen Saunaofen wird durch den Einbau des Dampfsteigrohres eine zusätzliche Konvektion erzeugt, die einen Ventilator unnötig macht, der ein günstiges Saunaklima sowie eine medizinisch günstige Temperatureinschichtung zerstören würde.In the sauna heater according to the invention, an additional convection is generated by the installation of the steam riser, which makes a fan unnecessary, which would destroy a favorable sauna climate and a medically favorable temperature stratification.

Ein unmittelbares Inhalieren ist mit dem erfindungsgemäßen Saunaofen auch in einem Zustand möglich, bei dem der Benützer sich bereits erkältet hat und aus medizinischer Sicht ein Saunagang nicht mehr zu empfehlen ist. Damit können selbst Personen mit erhöhter Körpertemperatur (Fieber) den Inhalationseffekt mit sauerstoffhaltiger Mischluft in feinster Verteilung ausnutzen.With the sauna heater according to the invention, direct inhalation is also possible in a condition in which the user has already caught a cold and from a medical point of view a sauna session is no longer recommended. This means that even people with an increased body temperature (fever) can use the inhalation effect with oxygen-containing mixed air in a very fine distribution.

Die Art der Anordnung der Verdampferwanne mit dem Dampfsteigrohr und der damit erzielten Leitung der sauerstoffhaltigen Mischluft von der Verdampferwanne bis zum Dampfaustritt in die Kabine verhindert darüber hinaus die Gefahr des Verbrennens oder des Verbrühens der Saunabenützer durch Spritzer von kochendem Wasser.The type of arrangement of the evaporator pan with the steam riser and the resultant conduction of the oxygen-containing mixed air from the evaporator trough to the steam outlet into the cabin also prevents the risk of burning or scalding the sauna user through splashes of boiling water.

Die weiteren Vorteile und Merkmale sind der Beschreibung eines in der Zeichnung dargestellten Ausführungsbeispieles der Erfindung sowie den Unteransprüchen zu entnehmen. Die Zeichnung zeigt einen erfindungsgemäßen Saunaofen in schematischer Darstellung im Schnitt.The further advantages and features can be found in the description of an exemplary embodiment of the invention shown in the drawing and in the subclaims. The drawing shows a sauna heater according to the invention in a schematic representation in section.

In einem durch Wände begrenzten Saunaraum 33 ist in der Nähe einer in der Wand 31 vorgesehenen Zuluftöffnung 11 ein Saunaofen 1 aufgestellt.In a sauna room 33 delimited by walls, a sauna heater 1 is set up near a supply air opening 11 provided in wall 31.

Der Saunaofen 1 besteht aus einem Gestell 2, das einen aus einem hitzebeständigen Werkstoff, z.B. Keramik, hergestellten Mantel 3 trägt. Im Gestell 2 ist ein Korb 4 zur Aufnahme von Steinen 5 eingehängt, dessen Bodenfläche mit Luftdurchlaßöffnungen 6 versehen ist. Eine Heizeinrichtung 7 ist unterhalb des Korbes 4 am Gestell 2 befestigt und mit einem elektrischen Anschluß 8 verbunden. Für die Heizeinrichtung 7 ist ein Temperaturregler vorgesehen. Unterhalb des Bodens 9 des Ofens 1 ist im Gestell 2 eine mit Flüssigkeit, vorzugsweise Wasser, gefüllte Verdampferwanne 10 derart angeordnet, daß zwischen dem Boden 9 des Ofens 1 und der Verdampferwanne 10 ein genügender Abstand bleibt. Durch diesen Abstand wird der durch die Zuluftöffnung 11 einströmenden frischen Zuluft bei Saunabetrieb ein ungehinderter Zutritt zum Ofen 1 ermöglicht. Die Verdampferwanne 10 hat Öffnungen 12 für die Frischluftzufuhr, die durch einen Schieber 13 stufenlos regelbar sind. Eine Heizvorrichtung 14 ist mit einem elektrischen Anschluß 15 verbunden. Die dem Ofen 1 zugekehrte Öffnung 16 der Verdampferwanne 10 ist mit einem Deckel 17 abgedeckt, von dem in Richtung des Ofens 1 sich ein oder mehrere Dampfleitrohre 18 erstrecken.The sauna heater 1 consists of a frame 2, which carries a jacket 3 made of a heat-resistant material, for example ceramic. In the frame 2, a basket 4 for receiving stones 5 is suspended, the bottom surface of which is provided with air passage openings 6. A heating device 7 is attached to the frame 2 below the basket 4 and connected to an electrical connection 8. A temperature controller is provided for the heating device 7. Below the bottom 9 of the furnace 1, an evaporator pan 10 filled with liquid, preferably water, is arranged in the frame 2 such that a sufficient distance remains between the bottom 9 of the furnace 1 and the evaporator pan 10. This distance enables the fresh supply air flowing in through the supply air opening 11 to be unhindered in the sauna operation. The evaporator trough 10 has openings 12 for the supply of fresh air, which are infinitely adjustable by means of a slide 13. A heating device 14 is connected to an electrical connection 15. The opening 16 of the evaporator pan 10 facing the furnace 1 is covered with a cover 17, from which one or more steam guide tubes 18 extend in the direction of the furnace 1.

Diese Dampfleitrohre 18 leiten den Dampfluftstrom ohne Berührung mit den Heizstäben 7 für Lufterwärmung durch das Innere des Ofens 1.These steam guide tubes 18 conduct the steam air flow through the interior of the furnace 1 without touching the heating rods 7 for air heating.

Am oberen Ende des Rohres 18 ist eine Fülleinrichtung 19 angebracht. Diese Fülleinrichtung 19 dient sowohl zum Befüllen der Verdampferwanne 10 mit Flüssigkeit als zum Dampfaustritt. Im Abstand vom Boden ist ein Sieb 20 zur gleichmäßigen Verteilung des Dampfes eingesetzt, wobei auf dieses Sieb 20 Heilkräuter gelegt werden können. Mittels eines Regelventils 21 kann die Zufuhr der Flüssigkeit von außen 22 aber auch von innen 23 geregelt werden.A filling device 19 is attached to the upper end of the tube 18. This filling device 19 serves both for filling the evaporator trough 10 with liquid and for the steam outlet. At a distance from the ground, a sieve 20 is used to distribute the steam evenly, and 20 medicinal herbs can be placed on this sieve. The supply of the liquid from outside 22 but also from inside 23 can be controlled by means of a control valve 21.

Auf diese Weise ist der Dampfgehalt im Saunaraum genau regelbar und die benötigte Menge an Flüssigkeit ist gegenüber den bekannten Saunaöfen wesentlich geringer. Je nach Bedarf können ein oder mehrere Dampfleitrohre 18 vorgesehen sein, die das Dampf-Luftgemisch von der Verdampferwanne 10 zur Oberseite des Ofens 1 und damit in den Saunaraum 33 leiten.
Das Sieb 20 sorgt für eine sehr feine Verteilung des Dampf-Luftgemisches, das in einer nahezu gasförmigen Vernebelung in den Saunaraum 33 gelangt. Mit auf das Sieb 20 abgelegten Kräutern oder Essenzen kann die medizinische Wirkung der Sauna, insbesondere beim Inhalieren, verstärkt werden.
In this way, the steam content in the sauna room can be precisely regulated and the amount of liquid required is considerably less than in the known sauna heaters. Depending on requirements, one or more steam guide tubes 18 can be provided which guide the steam-air mixture from the evaporator trough 10 to the top of the furnace 1 and thus into the sauna room 33.
The screen 20 ensures a very fine distribution of the steam-air mixture, which reaches the sauna room 33 in an almost gaseous atomization. With herbs or essences deposited on the sieve 20, the medicinal effect of the sauna, in particular when inhaling, can be enhanced.

Zur Kontrolle des Flüssigkeitsstandes in der Verdampferwanne 10 ist ein Füllmengenanzeiger 24 vorgesehen. Außerdem ist ein ventilgeregelter Flüssigkeitsablauf 25 in die Verdampferwanne 10 eingebaut. Die Zufuhr von Flüssigkeit aus den Vorratsbehältern 22 oder 23 kann in Abhängigkeit von Füllmengenanzeiger 24 oder einer Wassersäulenluftkammer 28 selbsttätig geregelt werden.A fill level indicator 24 is provided for checking the liquid level in the evaporator trough 10. In addition, a valve-controlled liquid drain 25 is installed in the evaporator pan 10. The supply of liquid from the storage containers 22 or 23 can depend on the fill level indicator 24 or a water column air chamber 28 are regulated automatically.

Zwischen den elektrischen Anschlüssen 8 der Heizstäbe für die Lufterwärmung des Ofens 1 und den elektrischen Anschlüsse 15 der Verdampferwanne 10 ist ein Schalter 26 geschaltet. Dieser Schalter 26 dient zur Umschaltung des Ofens von Trockensaunabetrieb auf Dampfsaunabetrieb.A switch 26 is connected between the electrical connections 8 of the heating rods for the air heating of the furnace 1 and the electrical connections 15 of the evaporator trough 10.
