Description

97328 Electric heater ion

As is known, ordinary hot water can be ionized when used as stove water. The water vapor rising from the stove is thus ionized.

5 Steam contains positive and negative ions, possibly also free electrons emitted from red-filament resistors, allotropic molecules, etc. These must be eliminated immediately before they spread to the sauna steam air. The steam air is let into the sauna space through a filter that "sucks" both positive and 10 negative ions out of the steam, using a positive and negative filter network, so the positive network absorbs negative ions and the negative network absorbs positive ions, etc. The ground potential connection also conducts other particles to ground. the steam enters the steam room of the sauna through the network.

15 Disadvantages and elimination of ionization have been considered in Pat. Application No. 940445 Steam Liquid. The present invention eliminates the disadvantage that oil fluid is not always available, and the advantage is that this invention is always action ready. Steam liquid and its ions; . 20 complement each other, but they can be used just as well separately. Its ions are also suitable for other combustion and other carts; filtration before they enter the indoor or outdoor air. From time to time ; ; such a device can then be washed or vibrated free of particles attached to it. Its ions are also suitable for liquids ·· ;; 25 for cleaning.

It is familiar from physics that thermoelectric or so-called Thomson-effect. In it, two different metals are connected to each other as a thermocouple (e.g. Cu and Fe wires.) When this connection point is heated and a sensitive galvanometer in a colder state is connected to one end of the wires, a direct current begins to flow in the closed circuit. The other metal is. . positive and the other negative, ie the connection point is like a battery with + and - terminals (Fig 1). It is known that the voltage difference "* - of this connection point depends on the temperature difference of the so-called hot connection head and cold measuring head * '* 35 connection head ** *: instead, it is cooled colder than the measuring head, 97328 2 the direction of direct current changes and the indication of the galvanometer is reversed.

After Lord Kelvin (= Thomson), Seebeck found that if a battery is replaced by a galvanometer, then, depending on the direction of polarity 5, the junction will either heat up or cool down.

This hot joint head can also be made of overlapping copper and steel nets (Fig. 2), which are placed above the stove stones in a very hot space, e.g. attached to an insulating wooden wall or the like. The nets are thus galvanically connected to each other from several places, but not in direct contact with the stove's ground potential frame or stove stones. The mesh fabric can also be made in such a way that the "warps" are e.g. steel and the "wefts" are in turn copper, i.e. only one bimetal containing two metals is made. The hotter the space on top of the heater, the greater the electromotive force (smv) generated in the network and the more efficiently it absorbs the ions generated.

This dense network combination allows steam water to pass through the stove stones, but at the same time filters the + and - ions out of it, especially 20 when the ionized steam vapor still rises through it before. . spread into the sauna air. The cold "measuring head" can be "V made of a simple resistance" instead of a galvanometer ("resistor") in order to close the circuit and insulate it, connecting it to the cold floor of a sauna, for example::.: 25 ground stone with other particles •• • j are allowed to discharge into the ground.If to increase efficiency • · · * · * * two separate isolated overlapping nets are used, the ground is “grounded” on one Cu side and the other on the Fe side.
