2. Description of the Related Art Heretofore, there has been proposed an air conditioner (hereinafter referred to as a conventional technique) including a main body case through which air flows and a filter and the like inserted in the main body case. The filter is an element for filtering air,
It consists of a case to keep this element in a predetermined shape, and in order to prevent foreign matter such as dust and dirt from adhering to the air conditioning equipment inside the main body case and being blown out into the room, it is generally the uppermost stream of the main body case. It is attached to the suction port on the side. Further, a lattice-shaped inlet grill is attached to the inlet for the purpose of protecting and decorating the air conditioner in the main body case.

[0003]

However, in the prior art, since the inlet grill and the filter are composed of separate parts, the main body case requires an installation space for each part. Due to the limited space, there is a problem that the filtration area of the filter is reduced and sufficient filtration performance cannot be obtained. If the filter is used for a long period of time, a large amount of foreign matter such as dust adheres to the filter, causing the filter to become clogged, and therefore the filter needs to be replaced. When performing such filter replacement work, there is a problem in that workability is poor because both the work of removing the intake grill from the main body case and the work of removing the filter from the main body case are involved. INDUSTRIAL APPLICABILITY The present invention makes it possible to increase the filtering area of the filter in a limited installation space near the passage opening of the frame to improve the filtering performance of the filter and to improve the workability of the filter replacement work. The purpose of the present invention is to provide an air conditioner.

[0004]

According to the present invention, there is provided a frame body having a passage port through which air passes, a filter for filtering air passing through the passage port of the frame body, and a filter which is detachable from the frame body. And the filter is attached to the passage opening, and a technical means including a case of the filter and a lattice member that also serves as a grill of the passage opening is adopted.

[0005]

According to the present invention, since the lattice member serves as both the filter case and the passage grill, the space can be saved by the installation space of either the filter case or the passage grill. . For this reason, the filtering area of the filter is increased in a limited installation space near the passage opening of the frame, so that sufficient filtering performance can be obtained. Further, at the time of the filter replacement work, the filter can be replaced only by the work of attaching and detaching the grid member detachably provided to the frame body, so that the workability is improved.

After that, the new filter 4 is fitted into the recesses 23 and 24 formed on the inner surface of the top plate portion 17 and the inner surface of the bottom plate portion 18, and the filter 4 is held in a corrugated shape.

Then, the suction grill 5 holding the filter 4 in a corrugated shape is pushed inward from the front side of the suction grill 13 so that the engaged member formed on the rear side of the top plate portion 17 of the suction grill 5 is engaged. The stop claw 22 is fitted to the convex portion 21 formed on the upper side of the suction port 13 of the main body case 3. in this way,
The filter 4 is also attached to the suction port 13 of the main body case 3 by being fixed to the front surface of the suction port 13 of the main body case 3.

[Effects of the First Embodiment] As described above, the rear seat cooling device 1 is only attached to the suction port 13 of the suction port grill 5 while maintaining the design of the general suction port grill 5. Since the corrugated filter 4 can be attached, the air in the vehicle compartment can be cleaned. Further, since the inlet grill 5 also serves as the case of the filter 4, space can be saved by the installation space of the case of the filter 4. Therefore, the filter 4 can be installed in a limited installation space.
Since the filtration area of (1) increases, sufficient filtration performance can be obtained. Further, since the structure in which one suction port grill 5 is attached to the suction port 13 of the main body case 3 does not need to form a complicated filter guide or case, mold cost is unnecessary. Further, since the suction port grill 5 can be easily attached / detached by the claw fitting using the elastic force of the resin, the filter 4 held in a corrugated shape on the suction port grill 5 can also be easily replaced. it can. Therefore, the workability of the replacement work of the filter 4 can be improved, and the work time of the replacement work of the filter 4 can be shortened.
The cost burden on the user can be reduced.

[Second Embodiment] FIGS. 7 and 8 show a second embodiment of the present invention. FIG. 7 is a view showing a rib member which is a separate component from the main body case, and FIG. It is the figure which showed the movable type inlet grille. In this embodiment, the filter 4

Is provided as a separate part from the body case 3. The rib member 3
Holes 3 into which the inlet grill 5 is fitted, on both side plates 31 of 0
2 is formed. Further, the rib member 30 is formed with rib plates 33 that hold the filter 4 at a constant pitch. A pin portion 35 that protrudes toward the inner surface of the main body case 3 is provided on both side plate portions 34 of the intake grill 5. Therefore, the suction opening grill 5 is rotatably supported by the suction opening 13 of the main body case 3 by the pin portion 35, whereby the movable suction opening grill 5 is configured.
Further, a hook portion 36 to be inserted into the hole portion 32 of the rib member 30 is formed on the inner side of the both side plate portions 34.

[Modification] In the present embodiment, the present invention is used for a rear seat air conditioner of a one-box type automobile, but the present invention is applied to other vehicles such as a ventilation device, a heating device, an air conditioner and an air purifier. It may be used for an air conditioner or a stationary air conditioner. In this embodiment, the main body case 3 is used as a passage opening for the frame body.
Although the suction port 13 is used, the air outlet 14 of the main body case 3 may be used as the passage port of the frame body. Also, as a frame,
A duct including an inside air inlet, an outside air inlet, a differential air outlet, a face air outlet, a side face air outlet, and a foot air outlet may be used. In this case, the present invention can be used for the face outlet, the side face outlet, and the like.

In this embodiment, when the filter 4 is held, the inlet grill 5 is laterally press-fitted and temporarily fixed, but when the filter is held, it may be integrated with the grill by an adhesive or the like. As another modification, in a grille having a passageway based on a vertical grid, if the vertical grid is U-shaped and the horizontal grid is triangular, the corrugated filter can be held without breaking the design. It is possible. The filter at this time may be installed so as to have a wave shape in the lateral direction of the passage opening.
