The subject of the present invention "is an apparatus for generating and distributing oxygenated (oxygen-rich) air in hospitals, private apartments, etc., with the aid of which the air in these can be improved and the temperature regulated. The oxygen to be distributed becomes the liquid contained in a container Air is taken and the formation of gaseous oxygen accelerated or regulated by a simple tilting device.
The attached drawing shows:
Fig. Ι the apparatus set up in the room, FIG. 2 the vertical section of the apparatus and FIG. 3 the perspective view of the separate base for the apparatus.

To achieve the desired purpose of providing living spaces with oxygen-rich air, becomes a container 1 with the two chambers 2 and 3 in the room on an adjustable Pedestal 23 set up. The mentioned chambers are formed in the container by the airtight closing partition 4, which carries the cup 5 in its center, in which liquid air flows through the obliquely through the upper chamber 3 Pipe 9 is passed. So that no impurities can enter, is at the top of the pipe a funnel 10 is attached which contains a mass of filtrate which may be present to keep away solid carbon dioxide, ice particles, dust and so on.

According to this invention, a part of the liquid air should rapidly under the action of the Heat from the air surrounding the device evaporate, while the bulk of the liquid air should be kept as cool as possible.

For this purpose, the wall 8 of the upper chamber 3 is most advantageous thin copper or aluminum bronze sheet, d. H. good heat conductors, manufactured while the wall 6 of the lower chamber is made of as poorly conductive material as possible Material made such. B. lead, glass and also with a casing 7, consisting Made of wool, felt, velvet or the like. Is provided. About the insulation of the cup To make it even more effective, the space of the chamber 2 can be hermetically sealed and as complete a vacuum as possible can be created in order to prevent the To restrict warmth of the room air to the slightest corn.

Instead of lead, glass and the like, porous, externally glazed earthenware can also be used by then letting liquid air seep through suitable openings in the wall 4 and so a low one Temperature generated. .

As soon as liquid air is introduced into the cup 5 and the chamber 3, the evaporation begins, stimulated by the warmth of the surrounding air from the containers 3.

The first 'product of this evaporation is nitrogen, and then a desired volume this gas has been discharged through the pipe 11 can be pure oxygen-rich air can be removed from the upper chamber 3 through the pipe 13.

The pipe Ii is "with the valve 12 and that Pipe 13 with the valve 14 for the purpose of regulating the gas respectively. Air outlet provided. From the Tube 13 gets the oxygen-rich air through tube 16, insert 21 and tube 17 in the distribution tubes 18 with the fine bores 19 passed. These perforations are mainly at the bottom of the tubes to avoid any To induce train. The tubes 18 are attached to the ceiling by the brackets 20. The insert 21 is used to heat the air that passes through it in winter. In in this case the hose is surrounded by a layer of asbestos.

The valve 14 can also be set up so that it only opens when there is a certain pressure in the container. The pipe 11 can also be used to derive Oxygen-rich air can be used if the nitrogen has been removed beforehand.

The safety valve 15 is arranged for the sake of safety. For further security the ends of the tubes 18 are also left open.

Evaporation can be accelerated by removing liquid air from the Lets the cup S enter the chamber 3 by giving the container an inclined position.

The chair-like base 23 facilitates the inclination of the container to any desired one Grade. For this purpose, the seat 25 is provided with the backrest 26 arranged perpendicular thereto rigidly connected and rotatably mounted. The container is placed on the seat 25 and this is held against the backrest 26 by means of the hooks 30. Grab the free ends of the hooks here behind the handles 31 of the container. The desired inclination is obtained by inserting the cross bar 27 in the appropriate Incisions in the arms 28.

Room 3 should be much larger than that ..Cup 5, because it not only has a large surface area for the liquid air emerging from the cup to allow evaporation, but also has to serve as a reservoir for the gas mixture being formed.

A vent or ventilation pipe 22 is arranged on the floor of the room so that the spoiled air can escape freely.

Claims (2)

Patent claims: 1. An apparatus for generating oxygen-rich air from liquid air, characterized in that in a container (1) which consists of two compartments (2 and 3), one of which (2) insulates against heat conduction and the other (3) ^;: Has a wall that easily conducts heat, a container (5) which is suspended from the intermediate wall (4) and separates the two compartments (2 and 3) and which contains the liquid air, opens with its open side into the heat-absorbing compartment (3), while its trunk is in compartment (2) insulated from heat, so that only a small part of the liquid air is exposed to evaporation, while the rest of the air contained in the vessel is protected from evaporation. 2. A frame to that characterized in claim 1 Apparatus to dispose of the liquid by tilting the container (1) Allowing air to pass from the vessel (5) to the bottom of the evaporation compartment (3), characterized in that the one carrying the container (1), with one supporting the latter in an inclined position Backrest (26) provided plate (25) is rotatably mounted and in any inclined position can be determined. 1 sheet of drawings.
