Electrically driven humidifier based on the evaporation principle

The invention relates to an electrically driven humidifier based on the evaporation principle, tit one removable hood with air passage openings, with a collar, which serves as an air duct and is fastened to the inner wall of the hood, in which a fan is arranged is, with a water tank, with a base shell supporting an evaporation mat on which the The hood and the water tank are on top.

In such known humidifiers, the evaporation mat is located in a water bath in the base shell. The evaporation mat sucks in through capillary action full of water and thus provides the air with the necessary moisture for the process of evaporation. The water bath is supplied with water from the water tank according to the cattle drinking principle. Once the water has reached a certain level in the base shell, no more water can flow out of the water tank.

The water tank is built on the base shell. Next to it, also built on the base shell, is located a removable hood that covers the evaporation mat. This hood is on its inside with provided with a collar that has the puncture of an air duct. Inside this collar there is a> .άη fan.

Ill i · · · ·

The hood is provided with air passage openings through which the air is sucked into the device or blown out of the device. In doing so, the air is constantly circulated.

The fan blows the air through or. against the wetted Evaporation mat. The air absorbs moisture according to the natural principle of evaporation and thus ensures that the air in the room is humidified.

These humidifiers have the disadvantage that they do not eliminate the pollutants in the air, so that these are thrown into the room again and again by the constant circulation. With these pollutants it is mainly about dust particles, pollen, odor;, toffe, etc.

The invention is based on an air humidifier P of the type described at the beginning, the task is based on |

To create a humidifier that, in addition to humidifying the air, also removes pollutants freed.

This object is achieved according to the invention in that a circumferential sealing surface is formed on the collar, to which an air-purifying filter is attached by means of an or a plurality of mounting pieces or pieces is pressed, each mounting piece in at least two locking elements engages, which are fixedly arranged within the interior of the hood.

The advantage here is that the arrangement of the air cleaning filter on the collar, which works completely independently of the evaporation mat. Thus, for the respective Type of Air Pollution The right type of air purifying filter can be chosen without affecting the humidifying effect of the device is impaired, or the evaporation mat must be adapted accordingly.

Furthermore, this has the advantage that the user lasts should forget to refill the water tank and the water runs out - the device is no longer inoperative runs "dry". At least a cleaning of the circulated air is guaranteed.

Depending on the type of air cleaning filter, this can preferably be be multi-part. It is quite conceivable that, for example, an air-purifying filter from different Layers, with each layer having its own cleaning function Has.

The invention is explained in more detail with reference to the embodiment contained in the drawing. It shows

Fig. 1 is a longitudinal section of an inventive Humidifier

The drawing shows an electrically powered humidifier based on the evaporation principle The outer housing is essentially formed by a base shell (7), a water tank (8) and a hood (5). The water tank (8) and hood (5) are built on the base shell (7).

In the base shell (7) there is an evaporation mat (9) which is in the operating position from a mounting cover (10) is held. The lower side of the evaporation mat (9) is immersed in a water bath (11). This water bath Ml) is supplied with water from the water tank (8).

The water tank (8) works according to the cattle drinking principle. As soon as the water level of the water bath (11) drops, lets the water tank (8) flow out until the level of the water bath (11) the valve opening (12) has reached. Then no more air can get into the water tank (8), which in turn means that no More water can flow out.

¹ V '4;

to achieve this effect, the water tank (8) apart from the valve opening (12) no further openings. The valve opening (12) is also used to open the water tank (8) refill with water.

At the valve opening (12) there is a valve (13), by means of a plunger (20) which is pressed against the bottom of the base shell (7) in the open position is held, as long as the water tank (8) is in the operating position. If the water tank (8) is removed, so the plunger (20) loses the stop, and the valve (13) closes by spring action, so that no Water can flow out of the water tank (8).

The evaporation mat (9) consists of hygroscopic materials, so that it removes the water from the water bath (11) sucks through its own capillary action and thus completely wets itself.

The mounting cover (10) is open on two sides (not clearly visible in the drawing) and has an air outlet slot (14) on the upper side.

A cylindrical collar (1) is attached to the inside of the hood (5). Inside this collar (1) is an electrically driven fan (15) is arranged, which is supplied with power via a cable (16).

A sealing surface (2) is formed on the lower side of the collar (1). An air purifying filter (6) is from two mounting pieces (3) - only one visible in the drawing - pressed against the sealing surface (2). These Retaining pieces (3) engage in two locking elements (4) and are held in place by them. The locking elements (4) are fixed in the interior of the hood (5). In the present embodiment, they are attached to the inner top of the hood (5).

The air is drawn through the fan (15) through air inlet openings not shown in the drawing on the hood (5) sucked in and in the direction of the arrow (18) passed through the device. It passes the evaporation mat (9) and is there after the natural Principle of evaporation humidifies. It is continued through the air outlet slot (14) and now happens the air cleaning filter (6). There the air becomes polluted by parts relieved and is now as humidified, purified air through the air outlet openings (19) blown out of the humidifier again.

The air cleaning filter (6) is a preferred embodiment shown in several parts. For example, qr can consist of an activated carbon part and a gel part or but consist of several blanks of the filter material used.

Furthermore, the drawing shows two guide pieces (17) in the base shell (7), which the mounting cover (10) in Hold position.
