Description
Air Humidification Device Field of the Invention The invention relates to an air humidifica-tion device comprising a housing having a front side and a rear side and having an air inlet opening and an air outlet opening as well as having a water connection for supplying water, and having a porous ceramic plate which is disposed in the air guide path of the housing formed by the housing between the air inlet opening and the air outlet opening in such a way that air passing through the air humidification device flows through the ceramic plate. Further, the invention relates to the use of the air humidification device for humidifying air in an apartment or a single-family house.
Background Air humidification devices are known in vari-ous designs. In particular, air humidification devices are known on the market, which can be attached to air ducts or air boxes of a building ventilation system of a single-family house, such that humidified air can be sup-plied to all rooms connected to the ventilation system.
Such air humidification devices use metal meshes as ele-ments in which the air comes into contact with the water.
However, such metal meshes may prove to be unstable and unsuitable from a hygienic point of view. From CH 687 417 it is known to use porous ceramic bodies as evaporation elements in an air humidification device which is ar-ranged directly in an air duct. Porous ceramic bodies in air humidifiers are further known from CH 696 694 as well as from EP 1 522 797, from EP 1 522 798 and from EP 1 541 932. Ceramic bodies are used in large humidifiers and, as Date Recue/Date Received 2021-05-04

2 mentioned in CH 687 417, are cleaned by a pyrolitic pro-cess or by acidification to maintain hygienic require-ments. However, this is too complex in practice for small air humidification systems for apartments or single-fam-ily houses.
Disclosure of the Invention The invention is based on the problem to pro-vide an improved air humidification device, which is par-ticularly suitable for use in ventilation systems of sin-gle-family houses or apartments.
This problem is solved in that the ceramic plate is at least partially surrounded on the front side by a frame, which frame is detachably fixed in the hous-ing, and in that the housing has a detachable and reat-tachable housing wall part, in particular arranged on the front side of the housing, during the removal of which the frame with the ceramic plate is accessible and can be removed from or inserted into the housing, respectively.
This design of the air humidification device makes it possible to easily remove the ceramic plate from the housing. The frame, which is usually formed of plas-tic, thereby enables on the one hand the handling of the ceramic plate, which has sharp edges, without any risk of injury to the user. Furthermore, the frame enables easy handling due to its detachable fastening in the housing and results in a well-defined insertion of the unit of the ceramic plate and the frame in the housing. Particu-larly preferably, the detachable housing wall part is ar-ranged at the front side of the housing which results in a further facilitation of the handling of the ceramic plate.
Preferably, the frame and the housing have cooperating snap-in fastening means, which result in an easy removal and insertion of the ceramic plate. Prefera-bly, the air humidification device is equipped only with Date Recue/Date Received 2021-05-04

3 a single ceramic plate, which also facilitates the han-dling and the preferred method of cleaning. It is actu-ally preferred that the frame and the ceramic plate are designed to be dishwasher safe, which allows an easy cleaning in a household dishwasher. In this way, a hy-gienic operation of the air humidification device by the user can be ensured in a simple manner. Accordingly, the ceramic plate with the frame at least partially surround-ing it is sized in such a way that it can be placed in a conventional household dishwasher for cleaning. Prefera-bly, the ceramic plate is designed as a single plate with flat plate sides, which is also advantageous for clean-ing.
Preferably, the water supply of the air hu-midification device in its housing is arranged in such a way that the water for air humidification is supplied from the water connection of the housing to the ceramic plate or is delivered to it, respectively, in particular is delivered directly to a front face of the ceramic plate. The direct delivery of water to the ceramic plate enables an efficient humidification, such that sufficient humidification for a single-family house or apartment can be achieved with a single ceramic plate. In particular, it is foreseen that through the water guidance of the air humidification device in the housing, the water can be discharged onto the upper side of the frame and the frame has water guide elements on the upper side for the dis-tribution of the water.
Further, for an easy mounting of the air hu-midification device on the outside of an air duct or an air box of a building ventilation system, it is preferred that the air inlet opening has a connection for an air hose on opposite sides of the housing and that the re-spective unused connection can be closed. It is further preferably foreseen that the air outlet opening is ar-ranged at the rear of the housing. This facilitates a mounting on the outside of an air duct or an air box of Date Recue/Date Received 2021-05-04

4 the building ventilation system. It is further preferred that the size of the air outlet opening on the rear side substantially corresponds to the width times length or area, respectively, of the ceramic plate not covered by the frame. Thus, a large volume of air can be delivered to the air duct through the preferably single ceramic plate. A collar around the air outlet opening allows for the substantially airtight connection to a corresponding opening in an air duct on which the air humidification device is mounted. Preferably, the rear side of the hous-ing is further configured in such a way that the housing can be attached with its rear side to an outer surface of an air duct or an air box of a building ventilation sys-tem. In this way, the air outlet opening can be aligned with an opening in the air duct or in the air box, and the humidified air exiting from the air humidification device directly enters the air duct or the air box.
The invention further relates to the use of an air humidification device according to the invention for humidifying air via the building ventilation system of an apartment or a single-family house according to claim 11. Thereby, the mentioned advantages are achieved.

Mode(s) for Carrying Out the Invention Figure 1 shows a frontal view of an air hu-midification device 1. This comprises a housing 2. An air inlet opening 3 is provided laterally on the left side of the housing and an air hose, not shown, for supplying air to the air humidification device 1 can be attached to the air inlet opening 3 by means of a connecting piece 33, which can belong to the device 1 or to the air hose of a building ventilation system. The air humidification de-vice 1 is externally attached to an only indicated air duct or air box 20 of a building ventilation system, in particular a ventilation system of a single-family house.
Furthermore, the device 1 comprises a water connection 5 to which a pipe supplying water to the air humidification device can be connected. There is generally provided a water drain 6 for residual water, which residual water has not been entrained during the humidification process by the air flowing through the air humidification device 1 and has dripped downwardly from the humidification ele-ment, which is a ceramic plate.

6 air humidification device which is formed by a porous ce-ramic plate is accessible and removable from or inserta-ble into the housing, respectively, which will be ex-plained in further detail. The housing can be made mainly of plastic and be essentially cuboid or cube-shaped, op-tionally with rounded edges, or be essentially cylindri-cally shaped.
The Figures 2 and 3 show a view of the rear side 8 of the housing 2. This comprises the air outlet opening 10. This may be surrounded by a collar 11, which projects into the air duct when the air humidification device 1 is mounted on the air duct via an opening therein. A seal 13 may be provided for an air-tight con-nection of the air humidification device 1 on the air duct. In Figure 2, the ceramic plate 12 of the air humid-ification device 1 is mounted in the housing so that the air which flows into the housing at the connecting piece 33 flows out of the housing through the porous ceramic plate 12 and into the air duct. A corresponding air guide path is provided in the housing 2 by means of internal housing parts, which need not be further explained to the person skilled in the art here and which can be provided in various ways. This air guide path is sealed airtight, such that substantially all air which enters the housing via the connecting piece 33 and the air inlet opening 3 exits the housing through the air outlet opening 10.
Thereby, the air picks up the desired moisture as it flows through the porous ceramic plate 12, which is sprinkled with water. In Figure 3, the ceramic plate with its frame has been removed from the housing so that the view through the air outlet opening 10 into the housing is unobstructed.
Figure 4 again shows the view from the front.
It can be seen that the air inlet opening 3 can also be provided laterally on the right side of the housing. If air inlet openings are provided both on the right and on the left side of the housing, the air inlet opening that Date Recue/Date Received 2021-05-04
The Figures 2 and 3 show a view of the rear side 8 of the housing 2. This comprises the air outlet opening 10.

A seal 13 may be provided for an air-tight con-nection of the air humidification device 1 on the air duct. In Figure 2, the ceramic plate 12 of the air humid-ification device 1 is mounted in the housing so that the air which flows into the housing at the connecting piece 33 flows out of the housing through the porous ceramic plate 12 and into the air duct. A corresponding air guide path is provided in the housing 2 by means of internal housing parts, which need not be further explained to the person skilled in the art here and which can be provided in various ways. This air guide path is sealed airtight, such that substantially all air which enters the housing via the connecting piece 33 and the air inlet opening 3 exits the housing through the air outlet opening 10.
Thereby, the air picks up the desired moisture as it flows through the porous ceramic plate 12, which is sprinkled with water. In Figure 3, the ceramic plate with its frame has been removed from the housing so that the view through the air outlet opening 10 into the housing is unobstructed.
Figure 4 again shows the view from the front.
It can be seen that the air inlet opening 3 can also be provided laterally on the right side of the housing. If air inlet openings are provided both on the right and on the left side of the housing, the air inlet opening that Date Recue/Date Received 2021-05-04
7 is not required is closed airtight by a plug. Depending on the mounting situation of the air humidification de-vice 1 on the air duct or air box of the respective building ventilation system, the air inlet opening on the left side can be used as shown in Figure 1 or the air in-let opening 3 on the right side can be used as shown in Figure 4 for connecting the air hose by means of a con-necting piece 33, while the other side of the air inlet opening is closed.
Figure 4 further shows that the detachable and reattachable housing wall part 4 has been detached and removed from the housing. It will be reattached to it later. It is evident that behind the housing wall part 4 the ceramic plate 12 becomes accessible, which is visible here from its other side than in Figure 2. The ceramic plate 12 is arranged in a frame 14, which surrounds the ceramic plate on the front side and has at least single retaining brackets, which hold the ceramic plate 12 in the frame. The frame may be completely closed around the front face or only partially closed. Instead of individ-ual retaining brackets, the frame can also have a circum-ferential edge at the front and rear side, which retains the ceramic plate in the frame. In the figures, the frame 14 is shown with only one line. The specific design of a frame made of a plastic material according to the above details is readily apparent to the person skilled in the art and the frame therefore does not need to be shown in more detail here.
The frame 14 is held in the housing in a de-tachable and reattachable manner, so that by detaching the frame from the housing, the frame with the ceramic plate can be removed from the housing and subsequently reinserted and reattached in the housing. Figure 5 shows the completely removed wall part 4 of the housing and shall further show that the frame has already been de-tached from the housing.

8 ceramic plate is tilted slightly forward during this pro-cess in order to more easily remove the frame with the ceramic plate from the housing in an upward direction.
For releasing and fastening the frame in the housing, a releasable snap-in connection with elements on the hous-ing and on the frame can be foreseen, which is indicated by the only indicated elastic tabs 15 in Figure 5, which tabs can be provided on the housing and can releasably engage in corresponding counterparts on the frame. On its bottom side, the frame may rest and be suspended in the housing, for example in an upwardly open U-shaped rail in the housing. Such releasable and reestablishable connec-tions are known to the person skilled in the art and need not be explained further here. From the in particular tilted forward position, the frame can be removed with the ceramic plate in an upward direction. The insertion is carried out in the reverse order. After insertion of the frame with the ceramic plate, the wall part 4 of the housing is fixed to it again. The frame with the ceramic element is arranged in an airtight manner in the housing by means of one or more seals, such that the air must flow through the ceramic element.
Because the air humidification device with the ceramic plate is arranged on the outside of an air duct or an air box, respectively, of a building ventila-tion system, the ceramic plate is easily accessible for cleaning. The removal of the porous ceramic plate from the housing of the air humidification device 1 can be performed easily and safely thanks to the frame, which is generally made of a plastic material and which protects the operator's hands from the sharp-edged parts of the ceramic plate. The removal of the ceramic plate allows for its cleaning in a simple way. Preferably, for ease of removal and cleaning, only a single ceramic plate is foreseen in the air humidification device 1 and its di-mensions with the frame are preferably chosen such that the frame with the ceramic plate can be placed in a Date Recue/Date Received 2021-05-04

9 household dishwasher, such that a cleaning of the ceramic plate and the frame can be performed using a dishwashing detergent and a cleaning program of the dishwasher. Ac-cordingly, the frame must be formed of a dishwasher-safe plastic, and in the case of the ceramic plate, its dish-washer-safe nature is generally given anyway. This simple cleaning possibility, which results from the simple and hazard-free removability and reinsertability, permits a hygienic operation of the air humidification device 1 with simple compliance with the desired cleaning inter-vals for the ceramic plate or for the humidifying means, respectively, of the air humidification device 1.
The Figure 6 shows the preferred supply of water for the air humidification by means of the air hu-midification device 1. Figure 6 shows a view of the lower part of the air humidification device 1 with the housing opened. It can be seen that a conduit 16 leads upwards in the housing from the water connection 5, which conducts the water introduced into the air humidification device at the water connection 5 upwards to the upper side of the housing. The water supply can be determined by a con-trollable electrical valve 17. This valve 17 can be con-trolled by the electronic control 18 of the air humidifi-cation device 1. It is known to the person skilled in the art how to design the control system in order to control the valve. By means of one or more sensors in the air path, which are not shown, the control system can deter-mine the actual humidity of the air and compare it with the desired and adjustable target humidity of the air.
This is also known to the person skilled in the art and will not be explained further here.
At the upper end of the conduit 16, the water is discharged from the conduit onto the ceramic plate.
This is preferably achieved in such a way that the water is discharged onto the upper side of the frame, and the frame is designed on its upper side with only indicated water guide elements 19, in particular channel-like water Date Recue/Date Received 2021-05-04 guide elements, to substantially uniformly distribute the water along and onto the upper front side of the ceramic plate, for which purpose the water guide elements have corresponding openings in the bottom thereof.
