Abstract

PURPOSE:To reduce the number of parts, to simplify the work of mounting and demounting of an air filter, and to prevent the rattling of the same by forming a recessed or protruding part for positioning the air filter on one side of an outer frame of the air filter, and by forming a protruding or recessed part for positioning the same on a position on the back surface of an inlet grille, which corresponds to the recessed or protruding part of the outer frame. CONSTITUTION:In the case where an air filter 7 is mounted, fitting pieces 12 provided on the lengthwise sides 14 of an outer frame of the air filter 7 and mounting holes 10 of a plurality of protrusions 9 provided at arbitrary intervals on both lengthwise sides of a suction grille 5 are brought into agreement with one another in such a manner that one lengthwise side 14 of the outer frame meets the corresponding lengthwise side of the inlet grille 5, and the respective fitting pieces 12 and mounting holes 10 are fitted together. Thereupon, a notch 11 of the air filter 7 is engaged with a U-shaped part 16 of the suction grille 5 to be slidden therein. Then, the fitting pieces 12 provided on the other lengthwise side of the air filter 7 are fitted into the mounting hole 10. In the case where the air filter 7 is to be removed, both widthwise sides 15 of the outer frame are held by hand, and the fitting pieces 12 on the one lengthwise side are removed from the mounting holes 10 of the suction grille 5 by utilizing the elastic force of the fitting pieces 12.

The suction port (5) is a suction grill attached to the suction port [4], and the cross section of the suction grill (5) is cut along the longitudinal direction of the air conditioner body (1). The air filter fitting (6) in the shape of a letter or U is attached to the suction grill (
5) is fixed at both ends with screws, etc.

(7) is an air filter with an air filter fitting (
It is attached to the recess of 61.

Next, the operation will be explained. Air filter fittings (6) each having an angled or ijU-shaped cross section are fixed with screws or the like to both longitudinal ends of the suction grill (5) facing the air conditioner body (1). The air filter (7) can be attached to the concave portion of each air filter attachment (6), and one longitudinal side of the attachment (6) has a suction grill (5).
) to prevent the air filter from falling.Next, attach the air filter (7) to the mounting bracket +61.
Complete the installation of the air filter by sliding it along the recess in the right or left direction in the longitudinal direction and fitting it.

[Problem that the invention seeks to solve]

Since the conventional air filter mounting device is configured as 0 or more, in order to install the air filter (7), it is necessary to attach the air filter mounting tool (51) to the suction grill (51).
6) had to be fixed with screws, etc., which required a large number of parts, and it also took time and effort to remove and install the filter, and there were problems such as the air filter (7) rattling after being installed. .

This invention has been made to solve the above-mentioned problems, and provides an air filter mounting device for an air conditioner that can reduce the number of parts, simplify the installation and removal of the filter, and prevent rattling. With the goal.

[Means for solving the invention]

An air filter mounting device according to the present invention.

In an air filter mounting device that has locking pieces on two opposing sides of an outer frame of the air filter, and locks the locking pieces to locking parts formed on the back surface of the suction grill, the two sides of the outer frame A positioning concave or convex portion is formed on one side of the inclination, and a positioning convex or concave portion is formed at a position corresponding to the mortar or convex portion on the back surface of the suction grill.

[Effect]

The air filter mounting device in this invention is:

When installing the air filter to the intake grill.

Positioning is achieved when the positioning recesses or protrusions provided on the air filter and the suction grille or the positioning protrusions or recesses are engaged.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, (1) to (7) are the same or equivalent parts as in the conventional device. The plurality of suction grilles (5) attached to the suction port (4) have a conical cross-section, and on both sides of the longitudinal direction are arranged at an arbitrary distance perpendicularly to the non-design surface (8) which is the back surface. In addition, a plurality of protrusions (9), which are locking parts, are integrally formed with the suction grille (51), and these protrusions (9) are integrally formed with the suction grill (51).
9) has a mounting hole α that allows all air filters (7) to be installed.
0 is formed. The air filter (7) has a notch fiυ which is a concave portion in the center of one side of the longitudinal outer frame α4, and has a notch fiυ on both sides of the longitudinal outer frame I.

At an arbitrary distance, attach the mounting hole αlI provided in the projection (9) of the suction grille (9) in the same direction as the air filter +71.
A plurality of fitting pieces fi2, which are locking pieces that can be K-fitted, are provided. αG is a U portion which is a convex portion formed integrally with the suction grill (5) attached to the ceiling panel (2).

To install the air filter (7), use the suction grill (
5) Nine or more protrusions (9) provided at an arbitrary distance in the perpendicular direction to the non-design surface (8) provided on both sides in the longitudinal direction.
9), and fit the fitting piece fi2 provided in the same direction as the air filter (7) toward one side of the longitudinal outer frame I of the mounting hole α0, and at this time, Slide the notch tiv provided at the center of one side of the longitudinal outer frame aa of the air filter (7) to match the U portion aS of the grill (5).

Next, the fitting piece a'a provided on the other longitudinal side of the air filter (71) is fitted toward the mounting hole αα.At this time, the air filter (7) is fitted by elastic force. Sometimes it is slightly deformed, but returns to its original shape after being fitted.

Next, when removing the air filter (71), hold both sides of the outer frame + Is in the transverse direction of the air filter (7) with your hands, and attach the fitting piece α2 on one longitudinal side of the air filter (71) to the air filter. (7) Using the elastic force, remove the mounting hole (I) provided on the projection (9) of the suction grill (51).

The air filter (7) is attached and detached in the manner described above. The notch all provided in the center of one side of the longitudinal outer frame α4 of the air filter (7) is connected to the suction grill (6).
It is formed to fit the U part ae of 1, and in order to ensure the 2 positioning during installation, even if the mounting hole ati is larger than the protrusion (9) of the air filter (7), This error can be absorbed.

In the above embodiment, the air filter (7) is provided with a notch α11, which is a concave part, and the suction grill (5) is provided with a U part tte, which is a convex part, but the number 9 is not limited to this. , it is clear that the unevenness may be reversed.
