A humidifier for use in a sauna stove

Abstract

 The object of the invention is a humidifier (3) for use in a sauna stove (1), comprising a high vessel (4) open at the top, forming a store for the water to be vaporized. This is intended to be placed in the stone space (2), or similar, of the sauna stove, next to the source of heat, when in use the heat from the heat source vaporizes the water in the vessel (4), to spread steam to the sauna room. The humidifier (3) comprises at least one cup (6) to be placed on top of the aforementioned high vessel (4), in which there is a channel (7) to lead the steam from the lower vessel (4) through the cup to the sauna room.

Description

[0001] The object of the invention is a humidifier for use in a sauna stove, comprising a high vessel open from above, forming a store of water to be vaporized and intended to be set in the pile of stones in the stove or a similar place close to the heat source, so that in use the heat from the heat source vaporizes the water in the vessel as steam to spread around the sauna.

[0002] Besides the water thrown on top of the stones of the stove, various kinds of small vessels are known, which are placed on top of the stones to vaporize water. In addition, various types of humidifiers are known, which are connected to the sauna stove. Scents and aromatic substances can be placed in the water being vaporized by them.

[0003] Finnish utility model No. 1965 shows one type of humidifier of the kind referred to in the introduction. A problem with this kind of humidifier is that it is irritatingly noisy in operation. Often the hot water bubbles from high vessels so violently that it creates some degree of danger.

[0004] This invention is intended to create an improvement over the type of humidifier referred to above. With the aid of the invention, it is desired to make the operation of the humidifier quiet and absolutely safe. The characteristic features of the invention are described in the accompanying Patent Claims. The rapid vaporization of the water is still achieved in a manner characteristic of a humidifying vessel, but the vaporization is controlled by means of a cup set on top.

[0005] There may be one or more high, most advantageously cylindrical vaporization vessels. The cup referred to is set on top of all of them and a duct runs from its base from the top of each vessel to the inside of the cup.

[0006] During vaporization, there is still a characteristic noise, though somewhat less than without the cup.

[0007] In what follows, the invention is described by reference to the accompanying Figures, which show one humidifier according to the invention.

Figure 1

shows the humidifier set in the stone space of an ordinary electric sauna stove.

Figure 2

shows the cup component of the humidifier in cross-section.

[0008] In Figure 1, the electric sauna stove is shown without the stones, so that the location of the humidifier 3 between the resistances 5 in the stone space 2 of the stove 1 can be seen. In this case, the humidifier consists of a pipe closed at the base, i.e. of a cylindrical reservoir, which is marked with the reference number 4 in the illustration. Cup 6 is on top of the cylindrical reservoir 4. There can be several cylindrical reservoirs in the same manner as shown in utility model 1965. The cup would then extend from its base to the tops of all the reservoirs. The cylindrical reservoir 4 is set on the bottom of the stone space, into which the sauna stones are placed. In this way it remains surrounded by stones. The heat of the stone space vaporizes the water in the cylindrical reservoir 4 so that steam spreads into the sauna both before and during bathing takes place there.

[0009] Cup 6 is placed on top of the cylindrical reservoir 4 according to Figure 1. The cup is most advantageously ceramic, but it can also be made from stone. A ceramic cup is highly durable.

[0010] Figure 2 shows the construction of the cup of the humidifier in greater detail. The base of cup 6 has a depression 9 corresponding to the shape of the cylindrical reservoir 4, so that cup 6 sits firmly on top of the cylindrical reservoir 4. There are small stones in the cup 6, which, with duct 7, effectively damp discharges of steam. In place of the stones, there could be, for example, a ceramic component, which forms, with the inner surface of the cup, a suitable outlet channel. The diameter of the channel 7 of cup 6 is 15 - 30 % of the diameter of vessel 4.

[0011] Channel 7 forms a path for steam from the cylindrical reservoir beneath into cup 6. Channel 7 ends in a protuberance 8 inside the cup, so that there is a small water space within the cup itself. There are grooves radial to channel seven on top of protuberance 8, which prevent the channel becoming totally blocked, even though a stone is placed on top of it.

[0012] Here, cup 6 is a separate component, so that parts can be easily serviced. It can also be permanently attached to the cylindrical reservoir, if this is wished.

Claims

1. A humidifier (3) for use in a sauna stove (1), comprising a high vessel (4) open at the top, forming a store for the water to be vaporized, and intended to be placed in the stone space (2), or similar, of the sauna stove, next to the source of heat, when in use the heat from the heat source vaporizes the water in the vessel (4), to spread steam to the sauna room, characterized in that the humidifier (3) comprises at least one cup (6) to be placed on top of the aforementioned high vessel (4), intended to be filled most advantageously with small stones, and in which there is a channel (7) to lead the steam from the lower vessel (4) through the cup to the sauna room.

2. A humidifier (3) according to Patent Claim 1, characterized in that the cup (6) is ceramic.

3. A humidifier (3) according to Patent Claims 1 or 2, characterized in that a channel in the bottom of the cup in set in a protuberance (8), when cup (6) has its own water space.

4. A humidifier (3) according to Patent Claim 3, characterized in that there are one or more narrow radial grooves in the protuberance in the cup (6), arranged to prevent the channel being blocked, even if a stone is placed directly on top of the channel (7).

5. A humidifier according to one of Patent Claims 1 - 4, characterized in that the diameter of the channel (7) of the cup (6) is 15 - 30 % of the diameter of the lower vessel (4).
