Description

[Detailed Description of the Invention] The present invention relates to an air conditioner in which a filter is attached to the back side of an inlet formed in a front cover.

Conventionally, in this type of air conditioner, a filter guide rail is attached to the back of the intake port on the front cover, and the filter is installed from the insertion port at the bottom of the intake port, but vibrations from the main unit's motor etc. Furthermore, because the inlet crosspiece of the front cover was long, the vibration amplitude was amplified in the center of the machine, causing the machine to come into contact with the filter guide rail, causing a chattering sound. .

In order to prevent this, the filter guide rail is installed in such a way that there is a large gap between the filter guide rail and the crosspiece of the front cover, but this goes against the current problem of thinning the main body. Met.

The present invention addresses the above points and provides an air conditioner that does not generate chattering noise even when the filter guide rail is closely attached to the crosspiece of the front cover.

To explain one embodiment of the present invention shown in the figure below, 1 is an air conditioner main body, 2 is a front cover that covers this main body 1, and an inlet port 3 is formed at the upper part of the front surface and an outlet port 4 is formed at the lower part of the front cover. There is.

Note that the suction port 3 is composed of a plurality of horizontally long crosspieces 5 and slits 6.

Reference numeral 7 denotes a filter insertion port formed in a stepped portion at the bottom of the suction port 3.

Reference numeral 8 denotes an evaporator disposed opposite to the suction port 3; 9 a fan casing forming a ventilation passage for guiding the wind from the suction port 3 to the outlet 4; and 10 disposed within the fan casing 9. I am a cross loaf fan.

Reference numeral 11 denotes a filter guide rail installed vertically on the rear surface of both left and right ends of the inlet 3 of the front cover 2, which has a substantially U-shaped filter installation groove 13, and a mounting piece 14 that projects upward and outward. The mounting piece 14 is attached to the back surface of the front cover 2 with screws or the like.

12 is a second filter guide rail that is also installed vertically on the back of the center of the inlet 3 of the front cover 2, and has a cross section of approximately H.
It has a shape and has filter mounting grooves 13 on the left and right sides, and mounting pieces 15 are protruded from the upper and lower ends and are attached to the back surface of the front cover 2 with screws or the like.

Reference numeral 16 denotes a guarding member made of, for example, rubber tape or flocked hair, which is attached to the entire front surface of the H-shaped filter guide rail 12 facing the front cover 2, and is arranged so as to come into contact with the crosspiece 5 of the front cover 2. There is.

Reference numeral 17 denotes a filter that is detachably attached to the grooves 13 and 13 of the filter guide rails 11 and 12 from the filter insertion lower.

When operation is started in the above configuration, vibrations of the motor of the main body 1 are transmitted to the front cover 2, and the front cover 2 resonates.

Since the crosspiece 5 of the intake port 3 of the front cover 2 is long, the vibration is amplified at this central portion, but since the vibration is absorbed by the buffer member 16, no chattering noise is generated.

In the above embodiment, the buffer member 16 is disposed over the entire front surface of the filter guide rail 12 in the longitudinal direction, but it may also be disposed at a position corresponding to the crosspiece 5 of the front cover 2 as shown in FIG. good.

As described above, in the present invention, when a filter guide rail is attached to the back surface of the front cover and a filter is attached to the filter guide rail, the inlet crosspiece formed on the front cover and the filter guide rail are connected. Since they are in close contact with each other through the buffer member, the buffer member can absorb the vibration of the front cover crosspiece and prevent the chattering noise generated between the core and the filter guide rail. Since it can be eliminated, it is possible to reduce the thickness.
