Description

SAUNA 7 IJÄS 714 8 0

The object of the invention is to prevent water from coming into contact with hot metal parts in sauna heaters or similar ovens, in which water is evaporated on the stove stones of the oven, which evaporates due to the heat of the stones.

It is known that both positive and negative ions are generated during the emission of steam if water hits both the audible metal parts and the stove stones. In addition, it is known that the abundant amount of negative ions in the sauna air is healthy, while the abundant amount of positive ions can even be unhealthy.

15 If the stove has been heated hot and has enough stones, there is not a great risk that water may come into contact with the metal parts of the stove when the steam is thrown. However, modern continuously heated heaters, as well as electric heaters, use quite a few stove stones, so that the steam water 20 can easily drain from the cracks in the stones into the metal parts and generate positive ions. When steam is thrown, water also easily enters the hot metal parts outside the stones of the stove if the steam is thrown carelessly. The latter can be prevented by carefully throwing steam water on the stove stones. But even this does not prevent the formation of positive ions if water enters the hot metal parts of the stove through the stones.

FI patent publication 52 807 discloses a stove structure in which 30 is a closed stove plate of some refractory mass or soapstone. However, it has no ducts for the passage of hot air. If the tile breaks, it must be completely replaced.

The stove plate according to the invention has the advantage of air flow and, in addition, the possibility of assembling a cover according to the size of the stove from the elements, as well as the possibility of easy repair.

The sauna heater according to the invention is characterized by the features set forth in the characterizing part of claim 1.

The invention will be explained in more detail with the aid of the figures shown in the accompanying drawing. The figures show an application for carrying out the invention. However, the invention can be applied in other ways within the scope of the claims.

Figure 1 shows an end view of a stove plate formed of stove elements;

Figure 2 shows a side view of a part of a sauna stove tile; Figure 3 shows a top view of a part of the same stove plate;

Figure 4 shows a side view of another stove element; Figure 5 shows a top view of the previous one;

Figure 6 is a side view of the element to be mounted on top of the element in Figure 5;

Figure 7 shows the previous one seen from above.

The stove plate consists of stove elements, which are preferably all the same, but can be different, for example, below than above.

Element 1 (Figures 1-3) is an elongate trough with grooves 3 »made in the edges of the walls 25 through which air can flow through the stove plate. Arrows 4 indicate airflow. There are grooves 5 »inside the plate in the elements, where the water that has not yet evaporated flows out of the gutter ends without going into the metal parts of the stove.

Figures 4-7 show another embodiment. The stove plate consists of the lower elements 6 according to Figures 4 and 5 and the cover elements stacked on top of them, Figures 6 and 7 · 35

II

‘71480 is thus stacked as a tile covering 6 of these elements. On top of these, cover elements 11 with a conical air space 12 and openings 13 are stacked. · When the element 11 is on the element 6, air can pass through the air hole 10 of the lower element 5 with its cone cones 12

The elements have grooves 9> 14 and 15 to increase the surface area. · Some of the steam water remains in these grooves and evaporates in them. Of course, some of the water 10 flows down along the surfaces of the elements and, assuming that the stove has been heated to a bath condition, has time to evaporate before it drains to the joints between the elements, from where it would enter the metal parts of the stove.

The shape of the elements 6 and 11 has been chosen as a square shape because the heater cover of both continuously heated and electric heaters is square or rectangular.

The elements can be made of ceramic or stone. This can be, for example, soapstone or other stove stone, which is tough and easy to saw.

The stove can be made in such a way that only the elements according to the invention are stacked in one or more layers covering the furnace. The stove can also be made in such a way that there is first a stove tile according to the invention and conventional stove stones on it, as much as is considered advantageous for the use of the sauna.

30 The stove plate could in principle be a uniform plate and not assembled from 1 element. However, the elements have the advantage that they are easier to manufacture and can be used to stack tiles of different sizes depending on the size of the stove. The manufacture of a uniform slab is made difficult by the fact that the slab must have 35 grooves or recesses which prevent water from passing through, and air ducts through which only air can pass. If _______ -. TT— 4 71480 The stove tile breaks, so the tile made of elements can be repaired by replacing the elements of the Risa or twigs with new ones when the solid tile has to be replaced with a completely new one.

It is advantageous to make the length of the stove element 1 so long that the element extends from the edge of the oven to the edge. The upper edge of the oven can also be separately covered with stove elements or elements made separately for this purpose, which prevent 1C steam water from hitting hot metal parts at the edges of the stove.

The structure of the elements as well as the tile may vary. The main thing is that the stove plate becomes such that it prevents water from passing through while allowing air to pass through. In the stove plate, the air grooves 3 are above the bottom 5 of the lower chute, whereby water cannot pass through the air duct through the air duct. In the stove plate formed by the tiles 6 and 11, the horizontal and vertical seams between the tiles 6 are so narrow and the water passage on the hot surface is so long that the water has time to evaporate before passing through, if the stove is in sauna condition.
