Fig. 2 shows the composite concrete segments with the recess 14 for firing.

In the middle chamber, which is surrounded by the water jacket, there is the heat source, the flue gases are through a recess on End of the combustion chamber passed through the water jacket in the outer jacket and thus heat the water from the outside. The oven has an inlet opening 87 for the water jacket and above the outlet opening 88, which circulates cold water through the thermosiphon principle through the water jacket and travels through the outlet opening 88 back to the bathing device 1. The oven can also be designed so that the exhaust gases are not - as shown in Figure 3 - are conducted over a large area around the water jacket, but are passed through several flues within the water jacket, this would have an easier cleaning advantage. This oven can be equipped with a lid for regulation.

4 shows the bathing device 1 on the metal frame 10, which is clad with fireclay bricks. The firebrick is heated by the heat source and, after burning off the heat source, returns the stored heat to the bath water and thus prevents the pool water from cooling down. As protection against burns on the hot firebrick, a metal sheet with or without superior insulation can be applied. This sheet is slightly pre-bent so as not to distort due to the effect of heat. 5 shows the Bαdeeinrichtung 1 on the concrete frame 12 in plan view, with drain device 28, bath container 2. The recess 14 is used to load with wood.

6 shows a bathing device 1 in section with a bottom support 4a as protection against direct firing from the underlying heating source, this bottom support 4a is equipped in the drawing with a seat 44. This bottom support 4a can be held by a screw in the ground or by a bracket, which is integrated in the side surface 4b of the wall. In addition, the central Haltearretierung 96 serves in the drain opening 28 as a holder of the bottom support 4a, it can be easily pulled out of the bracket 95 by loosening the Haltearretierung 96, the multi-part base support 4a for cleaning.

7 shows the connection of the individual segments 12a, 12b, 13a, 13b, 13c of the fireclay combustion chamber, which may have different contours. This shape of the segments has the advantage that the chamber itself leveled when assembling o- the height when yielding the substrate retains.

8 shows the plan view of the metal frame 10 with the drawer guide and drawer 80 pulled out with a grid 93. This combustion chamber can also be produced from individual sheet metal segments, which can have a receptacle for the firebrick and additional insulation. The firebrick warms the water after the heat source has gone out. The additional insulation, which sits between firebrick and outer panel, prevents further heat loss and warping (due to heat) of the sheet metal jacket. These individual segments can be connected to one another by means of bent tabs with the aid of, for example, screws and can be assembled and exchanged as desired so that, for example, two drawers 80 can subsequently be installed. 9 shows the upper wooden panel 37, which consists of several segments 42 which are interconnected by drop-shaped pins 43 a. These segments form a non-positive connection, which strongly prevents the wood from working. This edge sits on the side wall of the bathing device 1 and stabilizes it by means of a recessed groove 97 in which the upper edge of the sheet-metal jacket engages.

FIG. 10 shows a single wood segment 42 of FIG. In Fig.10, the drip edge 98 can be seen on the underside of the border, where the bath water or rain water can drain without getting to the outer wood paneling. Furthermore, the connection with one another can be seen as a teardrop-shaped recess 43b and as the opposite side of the teardrop-shaped pins 43a, which form a frictional connection.

1 shows a bathing device 1 as in Fig.l, although the combustion chamber is formed of concrete segments, which are easier to transport than a one-piece concrete frame. In Fig. 1, a zigzag or wedge-shaped and interlocking contour 13c is shown.

Fig. 2 shows the combustion chamber as a metal frame with the recess 90 and the guide for the drawer 80th

FIG. 13 shows the bathing device 1 in a funnel-shaped configuration. The funnel forms a better heat utilization due to the enlarged heat exchanger surface and at the same time serves as a flue gas diverter, ie the flue gases are directed to the right and left around the pool. Furthermore, the depression creates a more comfortable seating position. The sketch shows the expansion joint 46, which connects the two halves of the side wall 4b. The expansion joint 46 is a diaphragm, which is applied by means of a permanently elastic sealant on the impact of the two side wall halves 4b of the back and front. The elastic connection thus prevents the bathing device 1 from being blown up or damaged by frost. In the middle the Bαdeeinrichtung 1, the Ablαuföffnuπg 28 in the Seitenπwαnd 4b (or in the bottom 4α) Zulαuföffnung 30 is arranged. The water is sucked in for filtering in the middle and brought into a rotary motion by means of a sheet (nozzle), which sits in the inlet opening 30 in the side wall 4b. By combining the central suction and the lateral feed, a very small pump is sufficient for effective filtering. This arrangement creates in the middle of the pool 1 via the drain opening 28 a vortex that detects all foreign objects and dirt particles and feeds the interposed filter. The purified water passes again through the inlet opening 30 into the pool 1. For further amplification in this case the Coriolis effect can be exploited.

Fig. 14 shows the firing by the drawer 80 according to the invention. This is double-walled in the drawing, so it does not warp so quickly in the outer shell (ash collection container). The first floor is designed as a grid 93, so that from the outside through the air supply air from below through the grid 93 to the fuel and thus can burn the fuel very clean and effective. The ash falls through the grate 93 on the second floor, which is open to the rear, so the drawer 80 only needs to be raised to dump the ash. The front 99 is covered on the inside with fireclay. This protects the front panel 99 from the effects of heat and the associated distortion. The handle 91 is attached to supply pipes 82. By flowing through the supply air, the tubes 82 are cooled thereby the handle 91 remains cold during operation.

By heating with the drawer 80, it is possible to regulate the temperature of the bathing device 1, further can be grilled or smoked on the drawer 80 by attaching a corresponding attachment. The grate 93 in the drawer 80 may be made bent, this bias prevents warping. The lattice 93 can also be bent upwards at the end, so that no wood behind the drawer 80 upon reloading. able to see. The grid 93 can be quickly replaced by riveting at the sides.

In a further embodiment, the drawer 80 can also be made closed. In this case, a corresponding sheet must be provided in the metal frame with corresponding openings for the supply air.

The drawer 80 can simply be loaded with wood, the temperature regulated and the ash removed. By this controllable drawer 80, it is also possible to operate a bathing device 1 as shown in Figure 13, without waiting for the burning of the wood or operate a ground support.

The drawer 80 may be further regulated by a lid applied to the grid 93.

If the temperature in the bathing device 1 is too hot, the drawer 80 and thus the heat source can be completely removed.

The bathing device according to the invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a variety of design variations are possible, which make use of the solution shown even with fundamentally different type of execution.
