Description

The invention relates to a cabin in which both hot air baths and (real) Radiation baths are feasible.

An oven heats the air in hot air booths. The hot air then warms up gradually after the cabin walls, the furniture and the ceiling and the floor.

With this method, the air is always hotter than the wall. This kind Hot air cabins are used for bathing saunas (saunas), the one high air temperature and relatively low wall radiation characterize. One has immediately after entering the cabin a strong feeling of heat, especially in the Airways.

In infrared cabins, the inner wall surfaces emit (in the wavelength range Infrared C) or radiant heater (Infrared A) radiant heat in the interior. The climate is essentially determined by the perceived temperature builds up relatively slowly in the body core due to the absorbed radiant heat. The air temperature in the cabin is considerably lower than in the sauna; she can even be just a few degrees above room temperature at around 30 ° C.

The invention aims to enable both operating modes in one cabin. For this this special cabin must be equipped in such a way that you can choose between bathing types Choose saunas and radiant baths or from one type of bath to another can switch.

This effect is known by installing an additional convection oven in to achieve a radiation cabin. But you have to do a number of Accept disadvantages.  

So the stove needs a footprint that is lost as usable space and that Design options of the furniture significantly limited.

The hot stove must not be touched due to the risk of burns. There is also a fire hazard if flammable items are on the stove be filed; Incidentally, this is the most common cause of sauna fires.

If you equip a hot air cabin with additional infrared heaters, they stay that way Disadvantages of the oven exist, which are accompanied by the disadvantages of infrared radiators add up this type of installation. The spotlights need additional space, they restrict Freedom of movement require poor "illumination" with considerable Variations in intensity and a danger to the retina of the eyes, so none Safety glasses are worn.

There are also solutions (e.g. DE 43 27 542 A1) according to the one defined in the preamble Design known that the fresh air flow in a single wall section control mechanically or by fan. The problem with these designs is that missing connection next to each other or corner sections a mechanical or fluid mechanical functional unit. One is missing horizontal air duct connecting the warm air ducts of the wall sections. It seems to be obvious, such a transverse shaft in the wall heating sections to integrate. However, this is not feasible because it is the vertical frieze would be interrupted, which give the wall heating sections the required statics and which also carry the cabin ceiling.

There are also problems when crossing vertical exhaust ducts and in electrical switchgear integrated into the wall.

The throttle devices that have so far been operated individually are in use impractical; A solution is needed and needed with one hand or pushing a button controls all wall sections if possible.

Another major disadvantage of the aforementioned or similar types is that permanent heating of circulating air and / or fresh air, even with the  Radiation bath. This makes the air in the cabin relatively hot and therefore hot the desired climatic difference between the two types of bathing is too indistinct; something is missing the palpable contrast.

Another lack of known designs is the lack of meterability the air flow in the interaction of several, or optimally all, Wandheizsektionen.

In addition, in the interest of high component uniformity, the air routing and Control elements consist of a set of fewer identical parts that at different cabin sizes and floor plan shapes can be used.

Added to this are the high design demands customary in the industry; technical Mechanisms such as air flaps and their actuators air intake and Exit openings should be "invisible".

The invention has for its object the cabin described above to train that both types of bathing, radiation bathing or saunas, in higher and each more significant climate quality switchable can be carried out in the same cabin are.

This task includes in particular the following detailed problems to be solved according to the invention:
To implement a simple, controllable, fluidic cross-connection of the heating wall sections, which is suitable for all cabin layouts and sizes, which consists of only a few components, costs little and works well

This task is performed in cabins according to the preamble of claim 1 solved according to the invention in that at least one cabin base with elements to control the through several warm air ducts of different wall sections flowing air is equipped.

The basic idea of this main claim uses the effect of the influence of  Flow rate on the efficiency of convective heat transfer flowing or still air. This air, hereinafter referred to as "control air" can according to the invention by mechanical, cross-sectional changing means and / or controlled by pressure differences generated by a fan.

If air flows through the wall heating sections, hot air is generated and it is created Hot air climate for saunas in the cabin.

If there is no air flow in the wall heating sections, then the convective is not necessary Release of heat to the air. The thermal energy is then almost completely on the Transfer internal formwork and increase its surface temperature and therefore very much effectively the infrared C radiation emitted. As is well known, after the Stefan Boltzmann's law specifies the radiation intensity (heat flow density in kcal / qm h) in the 4th power with the surface temperature.

According to the invention, a variant of the elements used for control consists of a throttle device which is mounted on the inside parallel to the cabin base and which covers or opens inlet openings arranged in or on the cabin base. The throttle device is placed on and along the inside of the cabin base for the following reasons:
There is always a continuous installation space, regardless of which section type (e.g. a door, exhaust air section, control room section, section with steam generator) rests on the base,
it is not that hot, ie metal parts can be touched safely,
and the throttle device is almost "invisible", so harmless in design.

The preferred embodiment of this throttle device consists of a single or multi-piece shaft on the with the inlet openings of the control air corresponding closure elements are attached.

If the rotary flaps are constructed in several parts, they are mechanically one Movement unit connected.  

The bearings of the shaft are attached to the cabin base and preferably as above open hanger bearings. This design enables a particularly simple one Assembly that can be done after the walls have been set up.

The shafts of the rotary flaps, at least one side of the cabin wall, are with one another connected to a movement unit; so you adjust the flap of one Wall heating section, then everyone else turns.

Non-aligned rotary flaps, e.g. standing around corners, are z. B. in the form of a simple spiral spring, rotatably connected to each other.

According to the invention, the throttle device is moved by an actuating element, which in a preferred embodiment consists of a wooden stick attached to one suitable actuation point (approximately at medium height, suitable for the furniture) is assembled. A fixing device engaging in the actuating element is defined at least the OPEN or CLOSE position.

It is also possible, if more complex, the throttle device to move by electric motor or electromagnetic. The electric motor or the Lifting magnets are outside the cabin, e.g. B. arranged on the cabin ceiling and the actuating elements (e.g. pull rod or rope) depending on the position of the Closure element adapted accordingly. The advantage of such a motor Operation is particularly problematic in commercial systems Service. When choosing the type of bathing by pressing a button on the control unit the rotary flaps accordingly; no further explanation is required for the Bather.

In order to recognize which operating mode is currently running when entering a cabin, position detectors (the rotary flap position) are provided. In the simplest case it consists of a label OPEN / CLOSE on the actuator.

Illuminated displays are much more attractive, for example in combination with the  Cabin lighting. Appropriate lighting of the radiant walls indicate their heat radiation.

The above-described throttle device with a rotary valve is particularly suitable for smaller ones Cabins designed by private users at low cost.

According to the invention, an alternative operating mode control is provided in or on Cabin base a transverse duct in front of several warm air ducts different Connects wall heating sections. The Warm air ducts blown with control air in the sauna mode.

This transverse shaft in or on the base preferably consists of a rectangular tube integrated in the cabin base. This fulfills the following requirements:
High static strength, the pipe must support the cabin, large shaft cross-section in relation to the specified installation space, since metal or plastic can be made with small wall thicknesses, moisture protection for the wooden parts above it in bathing types with high humidity and to protect against condensate absorbed by the floor or cleaning water.

So that the control air can flow from the transverse duct into the warm air ducts, are holes in the top of the rectangular tube at short intervals different dosing elements available.

Dosing nozzles are plugged in at the exit points for the warm air ducts. those with a small outlet cross section at points of higher air pressure or with large outlet cross-section in the area of the shaft end at which the Pressure difference is only low. This will make it a pretty even one Hot air production in the warm air ducts reached and local overheating avoided, which could trigger the response of safety devices. Sealing caps are used in places where no air leakage is desired.  

The flow of air through the transverse shaft is controlled by at least one Fan generated.

The suction side of the fan is in recirculation mode, especially when Heating process, connected to the interior. This is because none The existing ventilation system at Switching to saunas not disturbed. The heating process is also running accelerates, as warmer air is heated further.

According to the invention, transverse shafts of different wall sides can be formed by corner parts be connected to each other. You can use it to create different corners Combine wall heating sections into an effective unit. This is for the Flow control in the cabin is important.

End caps, which can be inserted as required, close the shaft ends.

A particularly efficient generation of hot air is achieved by combining the Throttle device reached with the air control. Thereby the thermal Flow in the warm air ducts caused by the lift Fan-driven control air multiplied. The climate change is ongoing noticeably faster with increased hot air and reduced radiation.

In the case of the double function, supports are provided at intervals on the transverse shaft ( 120 ), which transmit the supporting forces at the connection points of the wall sections and fix the walls laterally with the protruding formwork. The distances between the supports are chosen so that they match the inlet openings of the warm air ducts.

So that the blowing air does not escape through the inlet opening, it is in Injector nozzles led into the passages of the lower frieze. Here is the Airflow accelerates, which through the venturi designed as a vent is still supported in the lower frieze.  

The electrical heat generators give per unit of time at constant voltage same amount of heat, regardless of how the amount of heat generated flows. If there is no convective heat emission when the control air is shut off, it increases The temperature of the sheet metal parts in the hot air shaft increases faster and the Wall temperature sensor switches earlier and with a shorter duty cycle. This Behavior, despite the high radiation temperature level, requires a considerable amount Energy saving with a shorter heating time. However, the control of the Temperature controller can be adapted to the respective bathing type.

According to the invention, two sensors of different types are therefore preferably provided. In a warm air shaft there is a fast-reacting wall temperature sensor on one Sheet metal part attached to high thermal conductivity, which the temperature controller at Radiant bath operating mode controls.

In the case of saunas, a standard air temperature sensor installed in the interior determines the controller insert.

The double function of the wall heating sections on the one hand as a source of heat radiation and on the other hand, as a hot air generator, appropriately designed heat exchangers are used ahead.

According to the invention, a large area is preferably used by the electrical heat generator Heat-conducting plate heated up, which distributes the heat over and over it Internal surface conducts to the heat exchanger. This heat exchanger is equipped with numerous ribs protruding into the warm air shaft. These form vertical ones Large surface convectors for convective heat transfer. Streams the Control air through the convector, then the ribs cool down, which creates a Heat flow driving inward heat gradient from the heat-conducting plate into the Hot air duct.

The temperature of the control air rises, which falls on the inner wall surface accordingly from., d. H. the wall heating section loses a significant proportion of its Radiation current density.

Depending on the design of the electrical heat generator, these are different with  connected to the thermal plate. Tubular heaters or heating tapes are on the Inside, heating foils arranged on the outside.

According to the invention, the fan is preferably located in the cabin wall above the Cabin base placed. One is suitable for the modular design of the cabin special (narrow) fan section provided that all except the fan associated devices (air inlets, sensors, adjustment elements, Cable connections) included as standard.

After the accelerated heating process, the boundary conditions for that change optimal indoor climate. Now interested in the desired air and Wall temperature distribution also the air exchange rate or the fresh air percentage.

Depending on the ventilation installed in the cabin, it may be useful to use the to combine the present invention.

In these cases, the fan section is additionally equipped with a controllable one Fresh air inlet equipped. The fan then sucks the warm one out of the cabin Recirculated air and at the same time, metered, fresh air.

Depending on the size and equipment of the cabin, dosing can be done by:
the control program function of a climate value,
and / or depending on the occupancy density,
and / or as a function of the ambient air temperature which the mixed thermostat measures and switches on the adjusting element of the fresh air inlet when the response value is reached.

In simple cases, the electromechanical drive is done by a handle replaced, which is arranged in front of the air intake.

It is also possible within the framework of the inventive idea, albeit less advantageous, instead of the integrated cross shaft in the cabin base, a pipe along the To fix the cabin base inside or outside in which the control air to several Warm air ducts is distributed.

FIG. 1a shows the cab base 12 in the embodiment with the rotary door 30 in cross section. The rotary flap 30 is open in the sauna mode. As a result of the thermal buoyancy in the warm air shaft, control air 40 flows from the interior 13 via the inlet opening 122 in the cabin base 12 through the passage opening 250 of the lower frieze 25 into the warm air shaft 22 of the wall heating section 100 .

In the exemplary embodiment, the rotary flap 30 essentially consists of the shaft 31 , the closure elements 32 fastened to it and the shaft bearings 33 . These shaft bearings are designed here as hook-in bearings 330 , into which the rotary flap can be easily hooked. (Details in Fig. 6).

If the radiation bath operating mode is desired, the rotary flap is set to the CLOSED position (dotted). The closure elements 32 now cover the inlet openings 122 , as a result of which the control air flow 40 is interrupted. This means that hot air is no longer generated in the warm air shaft, the internal formwork is heated up more, and the characteristic infrared C radiation climate is created in the cabin.

FIG. 1b illustrates the operation of the air controller 4. Through the cabin base 12 , which here consists of a rectangular tube 123 , the control air 40 , metered through the metering nozzle, flows through the through openings 250 of the lower frieze 25 into the warm air shaft 22 of the wall heating section 100 .

The nozzles available with different cross sections are selected so that, adapted to the local pressure drop, approximately the same amount of control air 40 reaches the connected wall heating sections.

In the sauna mode, a fan drives the control air and hot air is generated in the warm air ducts. If the fan is switched off, only a small amount of pilot air flows through the heating walls, braked by the metering nozzles and the friction losses in the pipe system; the radiation climate arises in the interior 30 .

Fig. 1c shows a combination of the constructive variations shown in FIGS. 1a and 1b.

Supports 121 are attached to the rectangular tube 123 , which transmit the supporting forces at a distance, in particular at the butt joints of the wall heating sections 100 . At the same time, they take on lateral forces and thus fix the sections of the cabin walls. The distances between the supports 121 correspond to the position and the width of the inlet openings 122 .

When taking a sauna, the rotary flap 30 is in the OPEN position and at the same time the fan conveys control air 40 through the injector nozzle 452 . This injector nozzle opens into the passage opening 250 , which is designed as a Venturi nozzle.

This fan-generated air flow supports the thermal buoyancy in the shaft, the air throughput is increased significantly and accordingly more hot air is conveyed into the interior 13 ; This makes the climate difference in the operating modes even more striking.

Fig. 2 shows somewhat schematically a vertical section of a wall heating section, shown above the base variant according to Fig. 1b. Fig. 2 could also be placed over Fig. 1a or 1c.

The known shell-like wall structure consists of the inner formwork 21 , the heat-conducting plate 52 with an integrated heat generator 50 , the warm air duct 22 with the heat exchanger 51 according to the invention, insulation 23 and the outer formwork 20 .

The outlet opening 24 through which the heated control air 40 enters the interior 13 can be seen at the top of the figure. The cabin ceiling 11 rests on the upper frieze 26 .

The Fig. 3 schematically show the structure of a mechanical throttle control 3 in the rotary valve construction 30 of a cabin in plan and elevation.

The cabin bases 12 are drawn about two times larger (distorted) than the cabin dimensions, so that essential details can be represented.

The Fig. 3a, the cab base 12 in plan view. As example, a pentagonal cabin was chosen medium size. Cross lines in front of the outer contour mark the connection points of the wall sections standing on the bases 12 . The rotary flaps 30 and their shaft bearings 33 can be seen on the inside of the cabin base 12 . The standardized rotary flaps 30 which are adapted to the wall section widths are connected with coupling elements 34 of standard length or with extended connecting couplers 341 or with articulated couplers 340 to form a movement unit.

The connection couplers 341 bridge non-heating sections, such as a door, a window or an exhaust air section; they are covered by stationary cover strips 320 , which visually continue the shape of the closure elements 32 .

The articulated couplers 340 installed at the corners can be (real) articulated shafts or, preferably, simple spiral springs, since these are sufficient to transmit the small torques.

The actuating element 35 can be attached to each rotary flap 30 . You will therefore always find a fitting location that is suitable for the furniture and is easily accessible.

When actuating the actuating element 35 , the rotary flaps 30 of all wall heating sections 100 are simultaneously adjusted in the same direction.

In Fig. 3b, the view of the door side can be seen from the inside. You can see the rotary flaps 30 coupled to a movement unit and their shaft bearings 33 , the coupling elements 34 or 340 or 341 and the actuating element 35 .

The Fig. 4 illustrate an air control system as an alternative solution to the above-described throttle control for the same cabin example.

FIG. 4a shows the cab base 12 in plan view. It consists of rectangular tubes 123 which are connected to corner parts 44 at the cabin corners. The free pipe ends close inserted end caps 46 .

At the top of the rectangular tubes 123 there are bores at standardized intervals into which metering elements 45 with an adapted passage cross section are inserted according to the assembly plan. Cap 450 close the rectangular tube at all points where no control air 40 should escape, for. B. under doors or other non-heating actions.

Dosing nozzles 451 of different passage cross sections are used under heating sections 100 according to the rule: the closer the fan, the smaller the cross section.

In this example, the air control 4 is divided into 2 systems with the fan sections 103 and 103 '. The fans 43 draw in the control air 40 from the interior 13 . The control air 40 is divided into two directions when it enters the transverse shaft 120 in accordance with the pressure drop.

At the open corners, corner parts 44 are inserted, which statically connect the rectangular tubes 123 to one another and seal the joint.

The ends of the transverse shafts 120 , 120 'are closed with end caps 46 .

Fig. 4b shows the view of the door side from the inside in elevation. The fan section 103 and then the heating sections 100 can be seen next to the cabin door 15 .

Fig. 5 shows a portion of the heat exchanger 51 in cross section. The ribs 530 connected to the heat conducting plate 52 form a convector-like heat exchanger arranged in the warm air shaft 22 with a large wall surface and high vertical partial shafts.

All commercially available types, the system-adapted installation of which is shown, are suitable as the electrical heat generator 50 . Tubular heating elements 500 and heating tapes 502 are placed on the inside of the heat-conducting plate 52 , and a heating foil 501 or the like is placed on the outside.

In Fig. 5a it is assumed that no control air 40 flows through the heat exchanger 53 . The amount of heat emitted by the heat generator 50 then flows, corresponding to the temperature gradient, into the inner formwork 21, from which it is emitted predominantly as radiant heat into the interior 13 .

In FIG. 5 b, the control air cools the heat exchanger 51 with its fins 510 strongly, as a result of which the heat gradient turns inwards and the thermal energy is predominantly released to the control air 40 .

Fig. 6 shows a simple embodiment of an actuating element 35 with the rod 350, the joint part 351, which is fixed to the closure element 32 of the rotary flap 30. Vertical movement of the rod 50 causes all of the rotary flaps 30 to open or close.

The end positions of the rod 350 are defined by a fixing element 36 ; they correspond to the rotary flaps position CLOSE down and OPEN up.

Figure 6 also shows a preferred embodiment of the shaft bearing 33 as a suspension bearing 330 . This avoids tedious threading; the completely pre-assembled flap section is simply inserted.

Fig. 7 shows the fan section 103 of an air controller 4.

In Fig. 7a is seen a cross-section in Sockelbereichmit the arrangement of the fan 43 between the outer casing 20 and the circulating air inlet 420, a lid with air inlet openings, which rests on the inner formwork 21 and the bottom of the cab base 120 above.

A tubular vibration damper 430 elastically supports the fan 43 on the rectangular tube 123 and directs the control air 40 driven by the fan into the transverse shaft 120 .

Fig. 7b shows the arrangement described in Fig. 7a in the view from the interior.

In addition to the narrow fan section 103 , sections of the adjacent wall heating sections 100 can be seen.

Fig. 8 shows the fan section 103 with additional air mixer.

Fig. 8a shows in section the air mixer 47 consisting of the patch on the outer formwork 20 with the fresh air intake 470 about the central axis rotatably mounted Mixscheibe 472nd By rotating this disc, openings in the mixing disc can be more or less aligned with openings in the fresh air inlet. This changes the fresh air inlet cross section from CLOSED to maximum OPEN. In simple systems, turning can be carried out manually on the handle 48 mounted on the inside.

In more complex systems, in particular those for professional use, an electromotive or electromagnetic adjusting element 471 is provided according to the invention for driving the mixing disk 472 .

The drive signal can be triggered by the mixer thermostat 473 , which monitors the temperature of the incoming circulating air 42 . When the heating temperature of the circulating air is reached in the saunas operating mode, the mixer thermostat closes the circuit of the adjustment element. The mixing disk opens the air inlet, fresh air 41 flows in and is added to the circulating air 42 in the mixing room above the fan 43 . The drive signal can also be generated by a signal generator that triggers the occupancy density of the cabin.

The drive signal can also be from the program of the control unit, for example from the room temperature, the heating time, the air composition or the Post-drying run can be derived from steam baths.
