Description

[Detailed explanation of the idea] The present invention relates to improvement of air conditioners.

Conventionally, it was the first indoor unit of a separate air conditioner.
A configuration as shown in the figure is known.

That is, a cooler 3 is provided behind the suction grille 2 on the front surface of the main body 1', a dew pan 4' is provided below the cooler 3, and a filter insertion port 5' is provided below the air suction grille 2. established,
A plate-shaped air filter 6' is inserted through this insertion opening 5' and slid along a guide rail 7 provided at the rear of the suction grille 2 to be attached.

According to this configuration, since the guide rail 7 is provided, the depth of the main body becomes longer by the thickness thereof, which makes it difficult to make the main body thinner, and there is a problem that the cost of the material for the guide rail 7 increases. .

The present invention has been developed to solve this problem, and as shown in FIGS. 2 and 3, an embodiment of the present invention is shown in FIG. 2 and FIG. The front and rear width of the insertion port 5 is narrowed to an extent slightly wider than the thickness of the filter 6, and the front rising wall 4a of the dew pan 4 is arranged near the rear edge of the filter insertion port 5 so that its extended surface intersects with the back surface of the suction grille 2. This problem was solved by slanting the front rising wall 4a obliquely upward from the top and locating the upper end of the front rising wall 4a near the back surface of the suction grille 2.

That is, according to the present invention, when the air filter 6 is inserted through the filter insertion port 5, the filter 6 is guided along the rising wall 4a of the dew pan 4, and then is slid upwardly while coming into contact with the back surface of the suction grille 6. It is held in a fixed position without falling in a doglegged state as shown in FIG.

The present invention is constructed as described above, and since the air filter 6 is mounted in contact with the back surface of the suction grille 2 without requiring a guide rail for the air filter 6, the depth of the air conditioner main body 1 can be shortened. It is possible to reduce the thickness of the guide rail, and also to save material costs for the guide rail, thereby reducing costs.

Claims (1)

[Scope of utility model registration request] A cooler is arranged behind the air intake grille on the front side of the main body, a dew pan is arranged below the cooler, and a plate-shaped air filter is inserted through a filter insertion opening formed below the air intake grille. In such a device, the plate-shaped air filter is made of synthetic resin to maintain flexibility, and the front and rear width of the filter insertion port is narrowed, and the front rising wall of the dew pan is formed such that its extension surface is An air conditioner, wherein the filter insertion port is inclined obliquely forward and upward from near the rear edge of the filter insertion port so as to intersect with the back surface of the suction grill, and the upper end of the front rising wall is located near the back surface of the suction grill.
