Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air filter that is detachably attached to a suction port of an air conditioner. More specifically, the air filter is configured to be elastically deformable so that it can be easily attached and detached without removing the suction grille. The present invention relates to an air filter mounting structure.
[0002]
[Prior art]
The conventional air filter mounting structure provided at the suction port of the ceiling-suspended type air conditioner is designed to remove the suction grill and clean the air filter as disclosed in, for example, Japanese Utility Model Laid-Open No. 4-136428. As disclosed in Japanese Utility Model Laid-Open No. 3-115328, examples of configurations in which the suction grill is opened and the air filter is attached are known.
[0003]
However, since the air filter is configured to be removed by opening or removing the suction grill, it takes time to remove and remove the suction grill, and if the suction grill is removed or opened during operation. Was dangerous because there was a risk of accidents such as hair being sucked from the air inlet of the air conditioner.
[0004]
For this reason, an air filter mounting structure that can be easily attached and detached without removing the suction grill shown in Japanese Patent Application No. 9-265419 has been proposed.
12 is an enlarged cross-sectional view of a main part showing an example of the above-described air filter mounting structure, and FIG. 13 is an enlarged cross-sectional view of a main part showing another example of the above-described air filter mounting structure.
However, in this case, a gap s is generated between the air filter 7 and the filter guide 6 as shown in the drawing.
[0005]
On the other hand, if the gap s is eliminated, the air filter 7 may not be easily inserted and removed.
On the other hand, since there is this gap s, the air filter 7 is not flush with the suction grille 5 or the front cover 4 as shown in the figure, and the air filter 7 is not flush. Due to the occurrence of warping and return, there has been a problem that the appearance may be similarly damaged.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the invention will be described in detail with reference to the accompanying drawings based on examples.
1 to 10, reference numeral 1 denotes a ceiling-suspended air conditioner main body suspended from a ceiling surface A along a wall surface B, 2 a main body casing constituting the main body 1, and 3 a main body casing. 2 is a partition plate that divides the inside into a heat exchanger chamber and a blower chamber, 4 is a front cover mounted on the front surface of the main casing 2, and 5 is a suction mounted on a suction port 8 provided in the main casing 2. A grille 6 is a filter guide provided substantially parallel to the inner surface side of the suction grille 5, and an air filter 7 is detachably attached to the inner surface side of the suction grille 5 by the filter guide 6. An air outlet that forms an air passage provided in the main body casing 2 and that communicates with the suction port 8, 10 is a fan motor provided in the blower chamber, and 11 is a fan motor driven by the fan motor 10. A blowing fan accommodated in single 12.
[0016]
The suction grill 5 is constituted by a large number of parallel horizontal rails 5a and a plurality of vertical rails 5a ′ connecting them, and the air filter 7 is disposed in the vicinity of the partition plate 3 on the inner surface of the suction grill 5. It has an insertion / removal opening 5c for insertion / removal on the side.
[0017]
Further, 7 is an air filter, 7a is a filter guide receiving portion, 7a1 is a front protrusion, 7a2 is a rear protrusion, 7a2s is a groove, 7b is a mounting portion, 7c is a side wall, 7d is a bent portion, 7e is a vertical rib, 7f shows a taper part, 7g shows a horizontal rib.
[0018]
The air filter 7 has a filter guide receiving portion 7a and a filter mounting portion 7b on at least both sides, and a frame having deformation means capable of elastic deformation perpendicular to the insertion / removal direction of insertion / removal from the insertion / removal port 5c. And a filter attached to the filter attaching portion 7b.
[0019]
The main body casing 2 is provided with a filter guide 6 that is connected to the insertion / removal opening 5c and guides the filter guide receiving portion 7a to the inner surface of the suction grille 5 in a detachable manner.
[0020]
When the air filter 7 is detachably attached, the air filter 7 is inserted into the insertion / removal opening 5c and elastically deformed, and is guided to the inner surface side of the suction grille 5 by the filter guide 6 and screwed with screws. It is configured to be screwed into the hole.
[0021]
This makes it possible to detach and attach more easily and accurately than the case where the thickness dimensions of the respective parts are formed with the same dimension without removing the suction grille 5, as described above in the prior art. In addition, it can be prevented that it takes time to detach and attach the air filter 7 or that the hair is sucked from the suction port 8 by removing or opening the suction grill 5 during operation.

Is connected to the filter mounting portion 7b that is bent into a corrugated cross-sectional shape.
[0023]
Accordingly, when the air filter 7 is inserted / removed from the insertion / removal port 5c, the air filter 7 can be easily elastically deformed perpendicular to the insertion / removal direction, so that the suction grill 5 is removed. The air filter 7 can be easily attached to and detached from the inner surface of the suction grill 5.
[0024]
Here, in this embodiment according to the present invention, the front projection 7a1 and the rear projection 7a2 are formed integrally with the frame constituting the air filter 7 before and after the filter guide receiving portion 7a. , Reducing material costs.
[0025]
And the said front projection part 7a1 is formed in the leaf | plate spring shape with the material which has elasticity, and the upper end part is provided in the side wall of the said filter guide receiving part 7a.
This is to urge the air filter 7 backward.
[0026]
The rear projection 7a2 is formed in a substantially U shape by an elastic material, and both ends thereof are provided on the side wall of the filter guide receiving portion 7a.
This is to press the air filter 7 forward.
[0027]
Further, a plurality of groove portions 7a2s are formed outside the rear projection portion 7a2 along the insertion / removal direction of the air filter 7.
This is effective for preventing sink marks due to thick wall and reducing the defect rate.
[0028]
Further, taper portions 7a1t and 7a2t are formed at the upper and lower corners of the front projection portion 7a1 and the rear projection portion 7a2, respectively.
This is to improve the insertion operability of the air filter 7.
[0029]
A gap k is provided between the stopper portion of the suction grill 5 and the air filter 7.
This is to ensure the effect of preventing the air filter 7 from protruding.
[0030]
Next, the operation of the embodiment of the present invention will be described.
Since the front protrusion 7a1 and the rear protrusion 7a2 are provided on the front and rear sides of the filter guide receiving portion 7a, the air filter 7 is arranged on the inner surface of the suction grille 5 at the position of the front protrusion 7a1 and rearward. It is pressed forward at the position of the rear projection 7a2.
[0031]
And the part below the said suction grill 5 of the said air filter 7 rotates centering | focusing on the said front projection part 7a1, and changes back.
[0032]
Therefore, the suction grill 5 can be easily attached and detached without being removed, and the gap generated at that time, the warp during the molding of the air filter 7 and the protrusion due to the return can be corrected.
[0033]
Furthermore, sink marks during thick molding can be prevented by the groove portions 7a2s.
Further, since the taper portions 7a1t and 7a2t are formed at the upper and lower corners of the front projection portion 7a1 and the rear projection portion 7a2, respectively, insertion becomes easy.
And since the clearance k is provided between the stopper part of the said suction grill 5 and the said air filter 7, the said protrusion can be prevented reliably.
[0034]
Alternatively, the front projection 7a1 and the rear projection 7a2 may be provided separately and fixed to the frame of the air filter 7.
In this case, it is possible to reduce the warping and returning of the front protrusion 7a1 and the rear protrusion 7a2 itself during molding as compared with the case where they are integrally formed, and the action can be further strengthened.
[0035]
