Stove with lighting apertures

An ordinary wood-burning steel stove (Figure 1) consists of the following parts: 1. Ashtray 5 2. Grate 3. Fireplace 4. Flue gas pipe 5. Stone chamber 6. Door 10 7. Stove casing 8. Covering

There are also heaters on the market today with a glass opening in the hatch, which facilitates the control of heating and gives the sauna a natural-fire feel. However, the problem is that the door is down and small in size. The potential of such a hatch for lighting and atmosphere creation is thus very limited.

In the solution disclosed in this application, the illumination aperture or apertures are located in the heater casing, in most cases at the top. Such a structure is shown in the front of Figure 2:: · · ·. In the structure shown in Fig. 2, large illumination apertures are located! ' · .. 20 heaters on both sides in addition to the front. The top of the body has been spread out in the structure of the heater, which has made it possible to further enlarge the illumination apertures. The large apertures' 111: have double glazing. This improves reliability. Possible water • * *: ,,, I splashes do not penetrate the hot glass surface and do not present a risk of breakage.

Double glazing reduces the heat loss of the heater casing, and the heat of the furnace •, '·· 25 better targets the heater stones. In the structure shown in Fig. 1, it is not possible to position the illumination apertures ... * in the part above the furnace. Obstacle is the firebox lid, which: -: The club serves as the base of the stone space. Figures 3,4 and 5 show a new structure which allows: _: large illumination apertures to be placed on the top of the heater casing.

The numbering of Figures 3, 4 and 5 is as follows: - Ash box 1 - Grate 2 - Door 6 5 - Coating 8 - Fireplace 9 - Flue gas pipeline 10 - Stone chamber 11 - Stove casing 12 10 - Stone chamber bottom reinforcement 13 - Illuminated opening 14 with double glazing - Illumination hole on the left 15 with double glazing 15 - Illumination hole on the right 16 with double glazing • · '·' 'In the current structure shown in Figure 1, the upper mantle of the furnace is located directly above the hatch (6). In the new solution included in the patent application of Figure 3, the stone space (11) and the upper mantle of the firebox (9) are constructed such that the stone space is only attached to the mantle at the top of the heater. Coming down from the top, the stone space is reduced and at the same time an unobstructed view opens up to the lighting openings. This way, the light from the heating fire can effectively illuminate the sauna room. As shown in Figures 3 and 4, a large surface area with a double,. openings (14), (15) and (16) with glass are located on the front mantle of the heater and on both sides of the · · · [25]. At the bottom of the stone space is built an additional structure constructed of shaped steel, which improves durability and thermal conductivity. Figures 3, 4 and 5, Part 13.

The flue gas is removed from an opening in the center of the furnace. After the opening, the gases 1 1 are led into the circulation duct on either side of the stone space and collected in a chimney for conducting * 30 at the top of the stone space. Such flue gas piping (10) is shown in Figures 3, 4, 5 and 6.

The flow direction of the gases is indicated by an arrow in the figures. Central flue gas removal helps keep glass surfaces clean and recycling in the stone space enhances the warming of the stones.

In the alternative of Fig. 6, the stone space is supported at the top at the front of the mantle. An opening in the upper casing of the furnace has a connection to the illumination opening above the door.

In order to position the illumination aperture, in the alternative of Fig. 7, the mantle of the furnace (21) is raised relative to the normal design, so that the aperture can be positioned above the aperture (6). The illumination power of this option corresponds to the one shown in Figure 6.

However, due to the higher furnace, the heat output is somewhat inferior to that of Figure 6. Part of the jacket elevation can be utilized as an enlarged stone space.

In the alternative shown in Figures 8 and 9, the illumination opening (14) is located in a circular heater sheath ''. The stone space is in this case supported on the front of the heater at the top of the jacket.

The circular shape of the diaper allows the illumination aperture to be freely directed to each situation, '' 20 possible special needs. When the stone space of the round-mantle sauna heater as shown in Figures 8 and 9 is fully supported at the top of the mantle, the lighting openings can be placed! * as appropriate sectors around the entire mantle.
