Abstract

The object of the present invention is to use the dried-out hot air produced by heat generators to obtain humidified air by interposing a screen of sponges (of suitable volume, and cross-braced) which are soaked in water. The gaps provided between each sponge 8 and each row of sponges do not interfere with the radiation of hot air from the convector. These sponges may have various shapes (cubic, rectangular, spherical), be broken down into strips 7 to increase the evaporation surface, etc. Soaked in water, they each achieve the maximum water absorption. Various layouts: a) as a single length, b) several lengths or rows of sponges, which are removable, arranged in parallel on an inclinable chassis, c) in staged radii inside pans coated with water, d) inside a grid.

Description

Devices for using spongy bodies for humidifying hot air
The present invention aims to humidify the air in a living room by evaporating the water soaked with sponges of an appropriate size.

Ie generating event of this invention, comes from an observation carried out during an experiment which consists in dipping a sponge 8 cm wide I2 cm long 4 cm thick in a tank filled with water.

By leaving this sponge vertically in the direction of its length 12 cm or its width 8 cm, it loses part of the soaked water. By cons if it came out flat in the direction of its thickness 4 cm, it will keep all of the water soaked.

A second experiment, consisting in depositing the same sponge vertically in the direction of its length in a tank containing I cm of water, will show us that it stimulates very quickly Up to 5 cm in height.

A third experiment carried out with cubic sponges of 4 cm, will concretize the fact that they do not lose water by taking them out one by one.

To confirm these observations 20 cubic sponges 4cm
nn were threaded on a round metal rod of 6. nV and separated by a spacer of 5 m / m (figure I).
After copious soaking or watering, no water loss
"" vertically and horizontally. (brass threaded rod n / ni)
There are currently humidifiers hanging from central heating radiators. Reduced volume, made of porous stone, water drips if the heating does not work.- They are prohibited for all radiant electric heaters, in oil bath, and others.

The latter bear the Invention n Do not cover "
In this case and in that of the floor heating, electric humidifiers are used. They consume a lot of current and do not act as a protective screen between the person breathing and the pulsating convector of dry hot air.

Effectively the aim of the present invention is to use the dried hot air produced by the convectors, to obtain by interposing a screen of sponges soaked in water, humidified air. Intervals between rows of sponges do not interfere with the radiation of hot air from the convector.

This screen can be produced in several forms while remaining within the framework of the claimed inventive function.

Thus the crucial point of this invention lies in the fact that the aforementioned experimental cubes 4 cm (This shape and dimension not being exhaustive) can be multiplied into strips of 5 m / m. thick, square or rectangular round. enlarged evaporation surface.

These slats inserted every 10 m / m bring the evaporation surface to 2 square meters or more for a screen of 50cm.x 50 cm.

As for the shape of the screen, another arrangement is presented with metalZic bowls, flared, superimposed at intervals of 6 to 7 cm.

The latter, waterproof, allow with a water level
of I cm, a degree of humidification and evaporation cons
so many sponges arranged in a fan Inside-
degree which can last several days.

Six 28 cm diameter bowls spread over one height
42 cm more Six fan sponges 5 m / m thick
offer an evaporation surface of two square meters.

 This surface is appreciable during a heat wave.

Finally, this invention is not limited to the two modes of
aforementioned achievement .. she embraces all the
laughing and will be better understood by referring to
schematic appended hereto.

Figure I represents sponges (I) cubic 4 cm put
in a row on a metal rod (2); each of them
being separated by a spacer (3)., at the top of this
rod a hanging ball (4) and a hook at the bottom
(5) for extension. (Brass or plastic threaded rod)
Figure 2 also schematically shows a screen of several rods supporting sponges and spacers available
seated vertically in parallel on a frame (6). the
rods are very easily removable to be moistened,
by soaking as described above.

 FIG. 3 represents a detail of FIG. 2, ie a circular sponge (7) of 50 m / m in diameter 5 m / n of thickness, with its spacer (8) threaded on a rod (9). detail of figure 2 represents several assembled sponges (I0) on a total height of 4 - 5 cm.

The evaporation area is smaller for these latter..humidity stays longer.

FIG. 4 represents metallic bowls (II) pierced in the center in superposition. the intervals are ensured by spacers (I2) with rubber seals (I3).

A brass rod (I4) with clamping nuts (I5) maintain the cohesion of the assembly. At the base of the floor support shoes (I6) .- at the top (I7) represents a grip and (I8) a decorative tray. Water level in each bowl (19) .- (20) represents two sponges of Figure 5 schematically arranged in a fan around a tubular axis (21). the flanges (22) Figure 4 could in another version of non-drilled bowls, rest on supports (23) of fixed support on lateral uprights (only one shown) (24) of a suitable frame. In the bottom bowl Figure 4 are arranged in bulk 4 cm cubic sponges, not multiplied into strips (25).
Figure 6 shows another form of bowl (26) superposabAe. in its center an elevation (27) obtained by stamping. On the left (28) sponges arranged in a collar as in Figure 7 for the detail and Figure 8 for the schematic assembly .- (29) shows rubber spacer washers. (30) a lifting disc and (31) a flexible threading rod,
Figure 9 shows spherical sponges (32) as in Figure 10 in a row on a flexible cable (33) .- the spacers (34) pass through the center of each sphere.

Figure II shows the first variant .. a duralumin grid, consisting of 40 m / m x 40 m / m x 25 m / m boxes ...

 Ies sponges are arranged in a checkerboard, one box on two grid (35) box with sponge (37) empty box (36).

FIG. I2 represents a pivoting screen assembly (38) already described in FIG. 2. A frame (39) with axis of rotation and blocking (40) protective grid (or decorative full plate 41) - An alternative embodiment consists in fixing the sponges, (with
necessary intervals) as well on flexible rods or wires,
that it could be: flat g on profiled plastic bands,
grids, flat or cylindrical plates, using different
technical bonding annuities; among others, sticky cars
(sponges with self-adhesive) for example two self-adhesive sponges
lantes close to each other can grip the wire
Thus, FIG. 13 represents a superposition of four crowns of sponges "glued" in a fan around a hub for each crown.- With a diameter of I6 cm (2 times 6 cm plus hub 4 cm, height 5 cm) total height of braced crowns 25 cm + they represent an evaporation surface of
O m2 700 and can absorb with total retention T liter I / 2 of water .- the grid (41 same number as in figure I2 is cylindrical) - As use, the aforementioned crowns as well as the
round or rectangular bowls (or trays), may be suitable
for interiors (apartments, premises), while
screens, (separate ramps, flexible rods or wires), will be pre
outdoors: terraces, verandas, greenhouses, cellars,
Hot countries
- It should be noted that non-fire elements can
be incorporated> into the constituents of sponges, for example:
rock wool (or mineral wool).
