BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-mounted air conditioner. In particular, it relates to the structure of a humidifier used in the air conditioner.

[0002]

2. Description of the Related Art Conventionally, there are the following methods for installing a humidifier of a ceiling-mounted air conditioner (hereinafter simply referred to as an air conditioner).

[0003] A type to be externally attached to a side plate.
Is disclosed in Japanese Patent Application Laid-Open Publication No. HEI 9-203 (1995). The configuration of such an air conditioner is shown in the longitudinal sectional view of FIG. As shown in the figure, a humidifier 30 is installed on a side plate of a casing 24 of the air conditioner main body 20 (hereinafter, simply referred to as a main body). Main humidifier 3
The main structural parts of the humidifier element 31 include a humidifying element 31, a water supply drain pan 32, a drainage drain pan 33, and a water level detector 3.
There are four. Further, the humidifier 30 is provided with a water supply pipe 36 and an electromagnetic valve 35 thereof. The other air conditioner components disclosed are well known, but are listed as follows. That is, 13 is a decorative panel, 14 is an openable and closable suction grille, 15 is a suction port, 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 discharged air.

Separate type As a method different from the prior art, a method illustrated in FIG. 6 has been put to practical use. That is, in this system, the humidifier 40 is installed in the ceiling separately from the main body 20, and the humidifier 40 and the main body 20 are provided by the duct 41 provided on the side plate of the casing 24.
Are joined together.

[0005]

However, the above-mentioned prior art has the following problems.

First, in the case of the prior art, a mounting hole needs to be formed in the side plate in order to install the humidifier on the side plate. Such machining work accounts for a relatively large proportion of the entire assembling work of the air conditioner, and it is desired that this machining work be unnecessary in order to increase the efficiency of the assembling work.

On the other hand, in the case of the prior art, a space for installing a humidifier is naturally required beside the main body. Such a structure is not preferable from the viewpoint of effectively using the limited space in the ceiling, and it is desired that the installation space be unnecessary. In addition, the work of duct connection is required at the time of on-site installation work, and it can be said that the connection work is not preferable from the viewpoint of simplifying the on-site work.

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

As described above, there has been a need for the prior art to improve the humidifier in terms of the installation property and the serviceability.

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

[0011]

According to the first aspect of the present invention,
The air conditioner includes a body, a decorative panel for covering a ceiling opening, and a humidifier disposed between the air conditioner body and the decorative panel.

According to a second aspect of the present invention, the humidifier according to the first aspect of the present invention is provided for each of a plurality of discharge air passages provided in the air conditioner body. .

According to a third aspect of the present invention, the humidifier according to the first or second aspect includes a chamber and a humidifying element disposed in the chamber.
A part of the humidifying element projects from the upper surface of the chamber facing the air conditioner body.

According to a fourth aspect of the present invention, a part of the humidifying element according to the third aspect of the present invention is protruded into a discharge air passage in the air conditioner main body. This is a friction engagement.

[0015]

According to the first aspect of the present invention, the humidifier is disposed between the air conditioner main body and the decorative panel, and the humidifier does not occupy a part of the space outside the main body.

In the invention according to the second aspect, a humidifying device can be provided for each discharge air passage.

According to the third aspect of the present invention, a part of the humidifying element is projected from the upper surface of the chamber.
The humidifying element can be made larger.

In the device according to the fourth aspect, the humidifying element can be made even larger than the humidifying element according to the third aspect. Further, since a part of the humidifying element is frictionally engaged with the main body drain pan, the humidifying element does not tilt in the chamber.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIG. 1 is a longitudinal sectional view showing a configuration of an air conditioner (indoor unit) according to a first embodiment of the present invention. In the figure, portions having the same symbols as those in FIG. 5 or FIG. 6 are the same as those in the prior art.

The feature of this air conditioner is that
The humidifier 10 is disposed between the humidifier 10 and the decorative panel 13. However, between the main body 20 and the humidifier 10 and the humidifier 1
A seal member 17 is provided between the decorative panel 13 and the decorative panel 13. The sealing material 17 is used for discharging air from the discharge port 16.
This is to prevent leakage before the air is blown out. As shown in the figure, the humidifier 10 comprises a chamber 4A made of a heat insulating material such as foamed polyethylene. In the chamber 4A, a blast air passage 8 facing the main body ventilation passage 27 and a suction opening 15 are provided. A suction ventilation passage 9 is formed. In addition, the heat insulating material 4B inside the two air passages 8 and 9 is integrally formed with the heat insulating material 4A constituting the chamber.

FIG. 2 is an enlarged longitudinal sectional view showing one blow-out ventilation passage 8 of the humidifier 10 and its peripheral portion.
FIG. 3 is a plan view of the humidifier 10. FIG.
As shown in FIG. 2, the upper opening 5 of the blow-out ventilation passage 8 is opposed to the main body ventilation passage 27, and the lower opening 6 is opposed to the outlet 16 of the decorative panel 13. The humidifying element 1 is disposed near the upper opening 5 in the ventilation passage 8. This humidifying element 1 is partially
Similarly, by being immersed in the tank of the water supply drain pan 2 fixed and arranged in the blow-out ventilation passage 8, the water supply drain pan 2 is supported by the water supply drain pan 2 and holds its position. Further, a drain drain pan 3 is fixed and arranged below the humidifier 1.

Since this air conditioner is provided with the humidifier 10 having such a structure, an inspection opening for performing an inspection service is provided on the ceiling surface 1.
There is no need to separately provide the same in 1. That is, the inspection can be performed by removing the decorative panel 13. Conversely, when the humidifier 10 is installed, the installation operation is extremely simple.

B. Second Embodiment FIG. 4 is a longitudinal sectional view showing a modified example of the humidifier, and in particular, a humidifying element 1A drawn by a solid line corresponds to the second embodiment. Here, the main humidifying element 1A is formed so as to protrude from the upper opening 5 of the ventilation passage 8, that is, to be larger than the height of the frame of the chamber 4A. Therefore, the number of elements can be increased only in the portion where the elements are increased, and the humidification ability can be increased.

C. Third Embodiment FIG. 4 also discloses a third embodiment. That is, the humidifying element 1B drawn by the broken line corresponds to the third embodiment. Here, the protruding portion is further elevated than the humidifying element 1A and extends into the main body ventilation path 27.
In addition, the front end 1B1 of the L-shaped cross section is hooked on the main body drain pan 21, and the support of the humidifying element 1B is strengthened by frictional engagement between the two parts. Thereby, it is possible to prevent the humidifying element 1B from falling in the direction of the arrow in FIG. Further, since the dimensions of the humidifying element 1B are further increased, the humidifying ability can be further enhanced.

[0025]
