Definitions

  • the invention relates to a sauna heater for a sauna with benches provided at different altitudes for sitting and / or lying people whose whole body is in the sauna room and which has a heating device which heats the sauna air and in which the cooled air in the region of the floor of the Sauna room is discharged and at least partially fed to the heating device for reheating and, in order to avoid turbulence and to achieve a uniform temperature stratification with low sinking speed of the sinking air in the sauna room, an air inlet opening admitting from the sauna room down to lower fresh air and circulating air and upper hot air outlet openings are completely separate, only part of the side of the wall-engaging shaft is provided, from which the heated air only passes into the area of the ceiling of the sauna room, and the heating device in the corner area between the vertical shaft section u nd hot air outlet openings are arranged in flow just before these.
  • a sauna heater in which, in order to achieve a more uniform temperature stratification, the hot air that heats the sauna emerges at the upper end of a shaft directly under the ceiling of the sauna cabin and is evenly distributed there. Air to be reheated is fed to the shaft directly at the bottom of the sauna cabin. Fresh air is also supplied via the shaft. Exhaust air is discharged a short distance above the floor at a point away from the hot air inlet.
  • the heating device can be provided in the horizontal part of the shaft in the region of its upper end. In practice, however, the heating is installed in the lower area, because then a better and more uniform flow is achieved in the shaft and in the outlet, because the previous sauna works without a fan.
  • the air circulation is only achieved by sensible design of the dimensions of the shaft, the position of the outlet and inlet openings and the dimensioning of the heating.
  • This sauna heater has the great advantage over the previously almost exclusively used heater with a stove standing in the room that it does not generate uneven radiant heating of the different body regions of the sauna bather.
  • the user with partial body regions is closer to the sauna heater than with other body regions.
  • the heating system according to DE-PS 19 23 496 causes an unusually uniform temperature stratification. This means that with the vertical convection in the Turbulence occurring in the usual sauna is kept away from the user, so that the resting air layer, which is only a few millimeters thick, is not injured and the thermal transition conditions are very favorable.
  • This sauna heater has proven its worth in 18 years. However, it requires a design that takes into account the necessary size of the heating and the necessary size of the shaft. Naturally, this also depends on the size of the sauna cabin. Especially in small sauna cabins for cramped conditions, the loss of space for the heating shaft with the dimensions resulting from the thickness of the heating appears considerably.
  • the exhaust air must be removed from the floor at a certain distance in order to generate a corresponding suction due to the temperature difference to the outside air.
  • This exhaust air opening can already be much lower than in the case of sauna cabins equipped with standard stoves in which the exhaust air is discharged at around 70 ° C. In the previous shaft sauna, the exhaust air must be removed at around 45 to 50 ° C. According to the air flow, considerable energy is lost. Accordingly, the connection values for the heating are still relatively high.
  • Free-standing electric circulation stoves are known from "Can the essence of the electric sauna heater be compared to the Finnish sauna heater? - Sanitary engineering 1951, pages 171 to 175". However, these take no account of the air movement and do not achieve a uniform temperature stratification, which is clear from a comparison of their design apparent from this document with DE-PS 19 23 496. The airflow that emerges in a small space with a high airflow at a considerable distance from the ceiling cannot be compared with the heating, which leads to an even temperature stratification with a slow sinking rate. These stoves have not been built for decades and have not given any suggestion to improve sauna heating systems for practical applications.
  • Climatic chambers for the production of artificial fever differ completely in their use from the sauna. Firstly, the patient's head lies outside an opening, only his trunk is treated. The fans, flow conditions, heating systems and ventilation systems are designed for the purpose of producing artificial fever and, despite their long history and their treatment in the aforementioned sauna specialist, have not been able to give any suggestion to heat the sauna with the help of a sensibly designed fan and to propose nevertheless with a configuration corresponding to the temperature stratification.
  • the invention has for its object to further develop a sauna heater of the type mentioned in such a way that, with less energy and smaller spatial dimensions, the heating of a sauna cabin with the uniform temperature stratification known from DE-PS 19 23 496 and slow sinking speed of the air as a whole Sauna room and good ventilation is made possible and is further improved.
  • a fan for slow air flow is provided in the shaft and that the shaft opens at the upper end into a distribution nozzle arranged directly under the ceiling, which diagonally warm air at least on two sides or from the corner of the sauna room under the lower surface of the Distributing blanket and that the heaters and hot air ducts are surrounded by partitions, which are washed by cooler, branched off from the shaft in front of the heater.
  • the air movement in the shaft which is forcibly generated with the appropriately large and slow-running fan, it can be made so thin that it does not take up any usable space. Since the air in the shaft is not conducted as hot air, but only at the low temperature corresponding to the circulation and / or admixing, no protective measures are required in the shaft area, but only in the area of the actual heating elements. However, these are not in the usable area, but in the upper corner of the sauna room, where nobody can be anyway.
  • the distribution nozzle can be made very flat and therefore does not take up any usable space in the entire sauna cabin.
  • the good ventilation conditions of the well-known shaft sauna without fan can be further improved because the sauna can now be operated with a slightly more increased, low overpressure in the sauna room and the metering of fresh air can still be done influence better.
  • the conventional sauna with free-standing heater is operated with a low vacuum, so that the air change is only possible by releasing relatively warm air.
  • a sauna operated with low overpressure ensures better air conditions even in unfavorable weather conditions or air conduction conditions in the surrounding area.
  • the fan which runs slowly and with a low air throughput, is expediently designed to be adjustable in terms of speed or air throughput.
  • the air throughput can then be adjusted precisely to the respective conditions and according to the conditions of the sauna cabin with regard to supply air, exhaust air and, if necessary, the wishes of the user.
  • the setting device is expediently designed so that it can be determined or limited to a value or setting range, so that no unintentional unfavorable adjustments can be made.
  • the air discharge openings or the air outlet are expediently provided in the lowest area of the sauna cabin at a point away from the air transfer between the distributing nozzle and the sauna room, preferably without an adjustment slide.
  • the coldest air can now be discharged directly on the ground, thereby gaining a considerable gain in terms of the amount of energy required.
  • the shaft effects always result in a sensible air flow, which is maintained even when the sauna is not heated and the fan is not being driven, at least to such an extent that sufficient air exchange takes place in remote areas and so that no stuffy air can arise.
  • the fan is expediently designed as a drum fan which extends essentially over the entire width of the shaft. Then you can apply the entire shaft evenly without special air routing measures and with completely missing or possibly very low air noise. Since the air is only heated in the upper end area, the fan can be accommodated at any point depending on the design conditions. So lets it should be arranged in the room areas under the benches, which are not used for sauna operation anyway.
  • the heating shaft can have a greater thickness there and accommodate the fan in this thickened area.
  • the thickness of the duct leading the air can correspond approximately to the thickness of the insulation layer of the other sauna walls, so that the duct lies directly under the wooden cladding. Since heat passing through the wood cladding is absorbed by the air flowing through, special insulation can be omitted entirely or almost completely at this point. As a result, a further gain in usable space is achieved, particularly in confined spaces.
  • separate supply openings for room air and fresh air to be reheated are expediently provided, to which adjustable slides are assigned.
  • the proportion of fresh air, the proportion of room air to be reheated and the proportion of room air to be forced out can be determined in a single room area according to the respective wishes and needs. These can also be operated and coordinated better. In addition, they can be combined into structural units or sub-units and, if necessary, combined with other components.
  • the openings for reheating room air and fresh air are expediently adjacent to one another and have a common slider which can be adjusted above the openings in such a way that when the cross section of one opening is enlarged, the cross section of the other opening is reduced and vice versa.
  • the setting slide or the setting slides are expediently assigned remote setting devices which can be equipped with at least one handle above the benches. So you can easily adjust the air conditions during bathing according to needs.
  • the adjustment slider (s) can also be assigned to an automatic adjustment device that works depending on sauna usage factors. This can e.g. Record temperature, air speed, air composition and influence them according to specified conditions.
  • the adjustment slide or slides with suspension and actuation can be combined into a common structural unit with the fan and its air guiding elements and possibly its housing.
  • all the elements that cause and adjust the air movement and air throughput can be inexpensively produced, easily transported, and easily assembled, and there is no need to pay attention to alignment and assignment during assembly.
  • the same size units can be used for different sauna sizes in certain areas can only be adapted to individual conditions by changing the fan speed.
  • the same considerations must also be taken into account for the design of the heating devices, the distribution nozzle and the hot air ducts, partition walls and covers. These are to be designed according to the needs of use as well as with regard to manufacture, storage, shipping and installation.
  • the covers of the heating devices or heating registers can be designed uniformly with the metal sheets forming the distribution nozzle. This also results in a structural unit of heating and distribution elements.
  • the sheets arranged at a distance above one another and carrying the different warm air currents can be connected to one another with spacer elements and, if necessary, attached to the sauna components or their enclosures. Because of the overall design of a wooden sauna, the distribution nozzle and the area of the heating devices are also expediently provided here with wooden cladding, which in turn is to be designed at a distance from the metal sheets for the purpose of washing with colder air.
  • the heating devices are expediently formed by heating registers equipped with vertically running heat exchange surfaces. This allows the air to flow through well, absorb the heat well and, on the other hand, the adjacent areas of the air duct and the sauna construction are exposed to the least amount of heat radiation.
  • the heating device or heating register can be arranged in various places in the upper corner area, depending on how you want to design the shaft structure, the air deflection, the nozzle arrangement and the installation. It is expedient if the heating registers are arranged in the horizontal part of the air duct directly in front of the distribution nozzles. There is enough space in this corner area without any loss of usable space.
  • the heating registers are advantageously preceded by a deflecting part, preferably made of sheet metal, which forms the corner region between the vertical air duct and the heating registers. This ensures that the required parts are installed safely and in accordance with the intended air flow, which can be prefabricated industrially and for different types of saunas.
  • the deflection part expediently expands between the vertical air duct and the area in front of the heating registers, so that with relatively small vertical, relatively cold air leading shaft is sufficient, but the largest possible cross-sections are available for heating. This is also possible without impairing the use of space in this area of the sauna room. Further refinements, points of view, advantages and features of the invention also result from the following description part of important embodiments and details of the invention dealt with on the basis of the drawings.

  • a deflection device 70 which directs the air pushed up by the fan (40) into the heating device.
  • Electrically heated heating registers (81) are provided there. These are provided with ventilated sheet metal cladding, through which cooling air flows branched off from the cold air flow flow. The air warmed up in the heating registers and the cooling air emerge slowly and evenly through a suitably shaped flat distribution nozzle (85) directly under the ceiling of the sauna cabin.
