[Industrial applications]

 This invention relates to a ceiling-embedded air conditioner. In particular, it relates to the structure of the humidifier used in the air conditioner.

[0002]

[Prior art]

 Conventionally, there are the following methods for installing a humidifier in a ceiling-embedded air conditioner (hereinafter simply referred to as an air conditioner).

Type of Externally Attached to Side Plate This type of technology is disclosed in, for example, Japanese Utility Model Laid-Open No. 1-174835. The configuration of such an air conditioner is shown in the vertical sectional view of FIG. As shown in the figure, a humidifier 30 is installed on a side plate of a casing 24 of an air conditioner main body 20 (hereinafter simply referred to as a main body). The main structural parts of the humidifier 30 are a humidification element 31, a water supply drain pan 32, a drainage drain pan 33, and a water level detector 34. Further, the humidifier 30 is provided with a water supply pipe 36 and its electromagnetic valve 35. Other disclosed air conditioner components are well known, but are listed below. That is, 13 is a decorative panel, 14 is a suction grill that can be opened and closed, 15 is an inlet, 16 is an outlet, 21 is a drain pan, 22 is a heat exchanger, 25 is a blower, 26 is a fan and 27 is a heat exchanger 22. This is a ventilation path for the air to be discharged more.

Separately Installed Type As a method different from the conventional technique, the one exemplified in FIG. 6 is also put into practical use. That is, in this method, the humidifier 40 is installed in the ceiling separately from the main body 20, and the humidifier 40 and the main body 20 are joined by the duct 41 provided on the side plate of the casing 24.

[0005]

However, the above-mentioned conventional technology has the following problems.

First, in the case of the prior art, in order to install the humidifier on the side plate, it is necessary to form a mounting hole in the side plate. Such processing work occupies a relatively large proportion in the overall assembly work of the air conditioner, and it is desirable to eliminate this processing work in order to improve the efficiency of the assembly work.

On the other hand, in the case of the conventional technique, a space for installing the humidifier beside the main body is naturally required. Such a structure is not preferable from the viewpoint of effectively using the limited space in the ceiling, and it is desirable to eliminate the installation space. In addition, duct connection work is required during on-site installation work, and it can be said that this connection work is not desirable from the viewpoint of simplifying on-site work.

Furthermore, in order to inspect the humidifier in both the prior arts, it is necessary to provide a removable inspection port on the ceiling surface (inspection port 12 in FIGS. 5 and 6).

As described above, there has been a need to improve the conventional technology in terms of improving the installability and serviceability of the humidifier.

The present invention has been made in response to such a need, and its primary purpose is to facilitate installation and service (maintenance, etc.) of a humidifier. A second object of the present invention is to improve the performance of the humidifier itself.
