Abstract

In an air humidifier, the housing of which has a fan and an evaporation body onto which the fan blows, and also receives in the lower part of the housing a water supply for the evaporation body, the evaporation body (11) is carried, upright, by at least one floating body (9) which lies freely on the supply water (2) and permanently dips with a section of small height into the supply water (2), while the remainder of the evaporation body (9) can be wetted hygroscopically, for reliable pumpless wetting of the evaporation body. <IMAGE>

humidifier

The invention relates to a humidifier, the Housing has a fan and an evaporation body that can flow against it by the fan, and in the lower part of the housing takes up a water supply for the evaporation body.

In known humidifiers, the evaporation body is erected upright in the housing and from above by means of a water distribution device provided with discharge openings wettable. Apart from the fact that the introduction of the water into the water distribution device is a pump Required, the known humidifiers also have the disadvantage that the dispensing openings assigned areas of the evaporation body Hurch Limescale builds up after a short period of use, which reduces the performance of the humidifier. aside from that The calcifications require frequent changing of the evaporation body, which requires cumbersome work power and is economically expensive.

It is the object of the invention to make the evaporation body reliably wettable without a pump and the useful life to extend the evaporation body.

According to the invention it is provided for this purpose that the evaporation body carried upright by at least one floating body resting freely on the storage water and with a section of low height is permanently immersed in the reservoir water, while the remaining part of the Evaporation body is wettable by hygroscopy. The evaporation body preferably consists of a paper Material and forms side-by-side extending folds, which with a section of low height in the reservoir water immerse yourself permanently. The evaporation body formed in this way can be produced economically, does not require any water distribution facilities for its wetting and the wetting takes place evenly and unaffected by the supply water level. The evaporation body is held in the storage water by the float, so that a reliable wetting of the evaporation body from bottom to top is established until the storage water is used up. The extensive wetting that takes place in the process avoids calcification in sections or areas, so that the evaporation body also has a long service life.

It goes without saying that the evaporation body on the storage water can be carried by a single float. The arrangement of two floating bodies is preferred provided, which are spaced by, e.g. u-shaped

Wire moldings are firmly connected to each other, their The webs remote from the reservoir water protrude into the folds of the same as supports for the evaporation body. The floating bodies can in particular by hollow cylinders be educated. It goes without saying that floating bodies of any other shape, e.g. spherical Can find floating body application.

In an embodiment of the humidifier it is provided that To provide evaporation bodies with a large number of perforations. The perforations enlarge the contact areas of the Evaporation body to the fan air flow and carry thus contributes to the improvement of the power output. It is advantageous if the evaporation body can be exchanged on the float to arrange. This enables the power to be achieved by simply exchanging the evaporation body to bring the humidifier to the maximum value or by exchanging the evaporation body for another To achieve changes in the performance of evaporative bodies,

Another embodiment of the humidifier provides that the housing of the same by a cup-shaped lower housing part that receives the storage water and an attachable part The upper part of the housing is formed which carries the fan and has openings for the supply air and exhaust air. Preferred the fan can be more extensive at the air inlet openings Connect the air guide cylinder, the length of which is such that the water-side front end acts as an abutment is used for the evaporation body at maximum water supply. The air guide cylinder also has the advantage that the fan wheel cannot hit the filter and may damage it.

Finally, the invention also provides measures for recognizing the degree of filling of the lower housing part with storage water simply by the fact that the floating body is movable behind a watertight window in the lower part of the housing has strip-shaped water level indicator firmly.

The invention is based on an exemplary embodiment in Drawing clarified. Herein mean:

In Figures 1 and 2, 1 is a cup-shaped lower housing part referred to, which is used to take up the water supply 2. In the area of a fold 3 there is an upper housing part 4 set up freely. The upper housing part 4 has inlet air openings 5 and exhaust air openings 6 and carries a fan 7 and an air guide cylinder 8 firmly connected to the upper part 4. According to the invention, two hollow cylindrical floating bodies are spaced apart on the storage water 2 9 hung up. The floating bodies 9 are firmly connected to one another by a number of U-shaped shaped wire parts 10 (Figures 1 and 3). An evaporation body is on the shaped wire parts 10 11, in particular made of a paper material. The evaporation body is through a strip provided with folds 11 'is formed and its height is dimensioned such that the lower ends of the

Foldings II ^{1 are held} by the floating body 9 in the storage water while the upper parts of the folds can be wetted by hygroscopically rising storage water. The evaporation body 11 is provided (FIG. 4) with a number of perforations 12, which increase the surface area of the same and help improve the contact between the blower air and evaporation body 11. The evaporation body 11 is held by the float 9, unaffected by the respective water supply, with the same immersion depth in the water supply 2, so that reliable wetting of the evaporation body 11 is ensured even when the water level drops due to consumption. Instead of a paper material for the evaporation body, another porous material provided with hygroscopic properties can also be used. The folds II ¹ create a large surface in the evaporation body, which is capable of large water discharge capacities.

When ^{the fan wheel 7 1} rotates, air is introduced into the housing via the air inlet openings 5 and is blown onto the evaporation body 11 between the folds 11 '. After the fan air has been enriched with water particles, the humidified fan air is discharged through the exhaust air openings 6. It goes without saying that the exhaust air openings can be arranged all around on the upper housing part 4.

The float 9 is with a strip-shaped approach 14 equipped, which can be seen as a water level indicator behind a window 13 in the lower housing part 1 from the outside is.
