Definitions

  • the invention relates to a heating device for a sauna, comprising a sauna stove which can be set up in free-standing fashion in the sauna room and is provided with a container having ceramic, heat-accumulating material such as stones, and with a heating system which heats this material.
  • Such a device is known.
  • the stones used in the sauna stove ensure a uniform heating temperature in the sauna. This is important in particular for avoiding great drops in temperature when the stones are sprinkled with a liquid, for example water.
  • This liquid which is introduced using a ladle or similar device, evaporates when it comes into contact with the hot stones, in consequence of which the humidity in the sauna increases as a result of the steam forming.
  • the stones When the stones are sprinkled with the much cooler liquid they will suddenly cool down. After some time this produces erosion phenomena in the stones. The result of this is that they gradually pulverize, so that in the end new stones have to be installed.
  • the object of the invention is to produce a heating device for a sauna of the type mentioned in the preamble, in which the stones and the heating elements are not exposed to such great erosion.
  • This object is achieved according to the invention in that within the heating system, in or underneath the container with ceramic material, provision is made for a liquid evaporation pipe which, with the exception of openings in the top face and a line connection, is connected to a liquid circuit.
  • the liquid now evaporates to steam in the heated evaporation pipe.
  • Such an evaporation pipe which is, for example, of metal, can withstand better than the stones the cooling which always occurs through the introduction of liquid. Moreover, it can be much cheaper than the stones and is simple to replace, should it ever fail.
  • the steam emerging from the evaporation pipe is at a much higher temperature than the liquid introduced. The steam then comes into contact with the hot stones and is thereby heated further to produce the desired effect of a steam surge in the sauna.
  • the erosion of the stones if present at all, is much less than if the liquid were to be sprinkled directly onto the stones.
  • a pipe for evaporation of a liquid is known per se from NL-C-162302.
  • This known tube is used in heating elements located in a special, separate heating room of the sauna, in which there are no stones.
  • the disadvantage of this design is that the combination of pipe and heating element produces only a slight heat-­accumulating effect, so that the temperature cannot be held entirely constant on evaporation of the liquid. The steam output is also thereby adversely affected.
  • This known device is therefore not suitable either for keeping the temperature in the sauna constant on evaporation of the liquid or for producing a suitable steam output, such as is possible with the heating device according to the invention.
  • the circuit for the infeed of the liquid can be designed in various ways.
  • a very simple design is a circuit comprising a line connected to the evaporation pipe having at its free end a suitable opening for pouring in the liquid.
  • the heating device according to the invention is designed in such a way that the liquid circuit is a closed circuit having a supply or mixture tank and a lone loop with pump which ensures continuous circulation, said line loop being provided with a branch line to the evaporation pipe, and with a valve whose throughflow time and/or quantity is adjustable.
  • the continuous circulation of the liquid has the effect that said liquid is directly available for infeed to the evaporation pipe once the valve opens.
  • this circulation ensures constant mixing of the liquid with the aromatic substances to be added thereto in the tank.
  • the valve here can, for example, be set in such a way that the liquid is fed in continuously in such low quantities that the evaporation pipe does not cool down too much and does not overflow.
  • the valve can also be designed in such a way that it always remains open only for a short time, so that it has to be operated again to obtain a new quantity of liquid.
  • the heating device is preferably designed in such a way that the valve is provided with a regulating element which can be operated for opening of the valve and has a setting facility for the period of time that the valve is open, and the regulating element also has a setting facility for the period of time, following the period that the value is open, that the operating mechanism of the regulating element is switched off.
  • the users of the sauna can now operate the valve as desired by, for example, pressing an operating button provided in the sauna.
  • pressing an operating button provided in the sauna By making a suitable selection of the time duration and that during which the valve on operation remains open or subsequently must remain closed, it is possible to avoid too much liquid being introduced or too much steam being formed.
  • the liquid can also be introduced fully automatically at certain intervals.
  • the heating device need not be operated to obtain steam. It is, however, possible with infeed at intervals to give steam surges, something which is not the case with continuous infeed.
  • the liquid circuit can be placed outside the sauna cubicle, the branch pipe being conveyed through the wall of the sauna cubicle to the sauna stove.
  • any volatile oil such as eucalyptus oil
  • added to the water remains mixed with the water, so that the infeed of the correct mixture is ensured at all times.
  • Another advantage is that the eucalyptus oil can be mixed directly with the water without the differences in viscosity giving rise to problems.
  • infeed systems known hitherto for a mixture of water and eucalyptus oil working according to the venturi effect, it was necessary to use a mixture of alcohol and eucalyptus oil in order to permit suction of this mixture along with the transporting liquid.
  • a quantity of liquid which is found to be too great for reasonable steam development must be transported, which entails the above-mentioned disadvantages of excessive cooling of the stones, excessive consumption, a health risk and the like.
  • Another favourable effect of the circuit used according to the invention is that the eucalyptus oil does not evaporate quickly from it, on account of both the forced mixing with water during circulation and the fact that the circuit is completely closed.
  • the sauna cubicle 2 which is accessible through door 1, contains a sauna stove 3, provided with heating elements 4 and a container 5 having stones 6.
  • the evaporation pipe 7, which has a feed line 8 for the liquid to be evaporated and also steam discharge holes 9, is also provided underneath the container 5 for the stones 6, and is surrounded by the heating elements 4.
  • the liquid is fed in through a regulating valve 10 from the liquid circuit 11, which is connected at both ends to the liquid supply tank 12.
  • the liquid is continuously circulated by means of a pump 13, so that the correct mixture of, for example, water and eucalyptus oil is always present at the valve 10.
  • the valve 10 can feed in the correct quantity of liquid fully automatically to the evaporation pipe 7, or can be operated from the sauna cubicle 2 by operating means which are not shown.
  • the pipe 7 can also be provided between the stones.
