DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the air conditioner of the present invention will be described below in detail with reference to the drawings. 1, 2, 3, 4, and 5, reference numeral 1 denotes an indoor unit main body of an air conditioner, 2 denotes a front cover detachably mounted on the main body 1 and an upper surface of the main body 1. The suction port 3 is provided in the main body 1 and a heat exchanger for exchanging heat of the air sucked from the suction port 2 is provided in the air passage, and a blower for sending the heat-exchanged air to the outlet port. A fan 5 is an air outlet comprising a blower casing 5a for blowing out the heat-exchanged air toward the room, 6 is a plurality of left and right wind direction plates rotatably provided behind the air outlet 5, and 7 is a blower. An upper and lower wind direction plate 8 rotatably provided in front of the left and right wind direction plates 6 is a lattice-shaped fan guard provided at the outlet 5 so as to face the blower fan 4 for preventing tentacles.

The fan guard 8 is made of a synthetic resin such as PP (polypropylene), and has an outer periphery formed by a band-shaped outer frame 8a, and a plurality of vertical ridges 8b extending vertically in the outer frame 8a; The ridge 8b and a plurality of horizontal ridges 8c extending in the left and right directions perpendicular to the ridge 8b are formed in a lattice shape, and are housed in the blower casing 5a of the outlet 5.

A plurality of protrusions 9 are provided on the upper surface and the bottom surface inside the blower casing 5a to lock the upper and lower back edges of the outer frame 8a of the fan guard 8, and 10 is a front portion of the stopper portion 9. The claw portions are provided opposite to each other, and are inclined rearward to lock the upper and lower front edges of the outer frame 8a with a triangular back surface. By inserting the fan guard 8 into the blower casing 5a from the front of the air outlet 5, the outer frame 8a climbs over the claw portion 10 and further inserts the stopper portion 9 and the claw portion.
The front and rear of the outer frame 8a are clamped by 10 and fixed in the blower casing 5a.

The plurality of left and right wind direction plates 6 are integrally connected to the front end of the longitudinal ridge 8b of the fan guard 8 via a thin-walled hinge 6a, and are composed of two sets of left and right wind direction plates A and B. On the bottom surface of each of the left and right wind direction plates 6, a convex connecting shaft 6b projecting downward is formed. Reference numeral 11 denotes a connecting plate which connects the plurality of left and right wind direction plates 6 to form left and right wind direction plate groups A and B. The connecting plate 11 has a substantially T shape, and the connecting shaft 6b is inserted through a horizontal portion thereof. A plurality of connecting holes 11a, and a convex sliding shaft 11 protruding downward at the lower end of the vertical portion.
b is formed.

Numeral 12 is formed at a position opposite to the rotation locus of the sliding shaft 11b in front of the bottom surface of the blower casing 5a,
The connecting shafts 6b of the plurality of left and right wind direction plates 6 are connected to the connecting plate 11 by a knurl made of a plurality of ridges sliding on the sliding shaft 11b, and the left and right wind direction plates 6 are manually rotated left and right. Thus, the sliding shaft 11b slides on the knurl 12 and stops rotating at the concave portion of the knurl 12 so that the left and right wind direction boards A and B can be set in desired directions.

In the above configuration, the fan guard 8 is formed in a lattice shape from a synthetic resin such as PP (polypropylene), and is exposed to the blower fan 4 and housed in the blower casing 5a of the blower outlet 5. By forming the left and right wind direction plates 6 integrally with the fan guard 8, the workability of assembling and the workability of disassembly in consideration of recycling are good, the number of parts is small, the cost is advantageous, and
The air conditioner is equipped with a fan guard that can prevent the formation of dew.

[0018]

According to the present invention as described above, the workability of assembling and the workability of disassembly in consideration of recycling are good, the number of parts is small, the cost is advantageous, and
The air conditioner is equipped with a fan guard that can prevent the formation of dew.
