Abstract

PURPOSE:To reduce the number of assembling steps at the time of fixing an air filter and the number of components, to extend the degree of freedoms of designing without lowering an operability of the filter and to improve the appearance in an air filter fixing unit to be used for an air conditioner. CONSTITUTION:An operating rib 6a of an air filter is disposed in a recess 3c between oblique suction beams 3a of a suction grille 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air filter fixing device for an air conditioner.

[0002]

2 to 4 show the construction of a conventional air conditioner and a fixing device for an air filter. Reference numeral 1 is an underframe body of the air conditioner, and a diagonal grille 3a is used for a makeup grill. A front frame 2 having a suction grill 3 configured so as to be opened and closed is attached. A blower 4 and a heat exchanger 5 are arranged inside thereof. An air filter 3 for collecting dust is installed inside the front grill 2 and the suction grill 3 along the guide surface 2a of the front frame, the guide ribs 2b, and the guide ribs 3b of the suction grill.

The air filter 6 is designed to be attached and detached by holding the rib 6a. After the upper portion of the air filter 6 is inserted between the guide surface 2a of the front frame 2 and the guide rib 2b,
The lower fixing claw 6b of the air filter 6 is inserted and fixed in the fixing hole 2c of the front frame 2.

[0004]

However, with the above-mentioned structure, there is a problem that the fixing claw 6b of the air filter 6 is disengaged from the fixing hole 2c of the front frame 2 during transportation of the air conditioner, and the air filter 6 It was a factor of increasing the assembly man-hours such as taping to the left and right of the and increasing the cost.

Further, the suction bar 3 of the intake grill 3 is designed.
When a is to be formed below the ribs 6a of the air filter 6, it is difficult to form the ribs because it hits the ribs 6a. If the height of the ribs 6a is lowered to avoid hitting, the operability of the air filter deteriorates. It was a factor that caused

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and its purpose is to reduce the man-hours and the number of parts when fixing the air filter and to reduce the operability of the air filter. It is to expand the degree of freedom in design and provide an air conditioner with improved aesthetics.

[0007]

Therefore, as a means for solving the above problems, the operating rib of the air filter is arranged in a concave portion formed on the back surface of the oblique suction bar of the intake grill.

[0008]

With the above-mentioned means, it is possible to reduce the number of steps and costs when fixing the air filter, and to expand the design freedom and improve the aesthetic appearance without deteriorating the operability of the air filter. ..

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, reference numeral 1 denotes an underframe body of an air conditioner, to which is attached a front frame 2 having an intake grill 3 constituted by an oblique suction difference 3a. Is provided with a blower 4 and a heat exchanger 5. An air filter 6 is attached on the windward side of the heat exchanger 5 so as to be held by the front frame 2.

The air filter 6 is provided with an operating rib 6a so as to enter the recess 3c of the oblique suction bar. The concave portion 3c of the suction bar has a size such that the rib 6a does not rattle. Alternatively, ribs for preventing rattling are provided from above and below when the rattling is large.

In the above structure, the air filter 6 is fixed by the concave portion 3c of the suction bar when it is transported or the like, so that it can be prevented from coming off.

[0013]

As is apparent from the above-described embodiment, by disposing the operating rib of the air filter in the concave portion between the oblique suction bars of the suction grill, the air filter can be prevented from coming off, and the air filter can be prevented. It is possible to reduce man-hours and costs when fixed, and to expand the degree of freedom in design without lowering the operability of the air filter, and to improve the aesthetic appearance, which is a great effect.
