Abstract

PROBLEM TO BE SOLVED: To prevent any gap from being formed between a wind interruption member and a heat exchanger by preventing the wind interruption member from being deformed owing to expansion with heat when a lower inclination part of the heat exchanger is removed and the wind interruption member is provided at that position. SOLUTION: The present air conditioner is adapted such that a wind interruption member 8 is laid between a rear part of a rearward inclination part 3b and a drain pan 7 when a heat exchanger 3 is installed from which a downward inclination part 3c is removed, and the wind interruption member 8 and a rear end of the rearward inclination part 3b are sealed with a sealing member 9. Hereupon, a substantially recessed-shape stopper part is formed in a front part of the wind interruption part 8 including a stopper pawl 8a for engaging the rear end and a front surface side of the backward inclination part 3b, and the rearward inclination part 3b is held with the stopper part.

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 (A) and 1 (B) and FIG.
2A and 2B, reference numeral 1 denotes an indoor unit main body of an air conditioner, 2 denotes a filter provided on the front and top surfaces of the main body 1, and held inside by a filter guide 2b.
A heat exchanger provided in an air passage connecting the suction port 2 and an air outlet 5 provided at a lower portion of the front surface of the main body 1 is provided with a heat exchanger 3 and a heat exchanger 4 is provided with the heat exchanger 3. A blower fan 5 for sending the sucked air to the outlet 5 is used to blow out the air sucked from the inlet 2 by the blower fan 4 and subjected to heat exchange in the heat exchanger 3 toward the room. Outlet.

The heat exchanger 3 has a vertical portion 3a and a vertical portion 3a.
A rear inclined portion 3b inclined backward from the upper end of 3a, and a downward inclined portion 3c inclined downward from the tip of the rear inclined portion 3b, the base 6 constituting the air passage A drain pan 7 is provided on the back side, and the drain pan 7 receives the condensed water dropped from the lower inclined portion 3c.

When the heat exchanger 3 from which the lower inclined portion 3c is removed is installed, the main body 1 has a wind shielding member 8 provided between the rear end of the rear inclined portion 3b and the drain pan 7;
By sealing the space between the wind shield member 8 and the rear end of the rear inclined portion 3b with a seal member 9, it is possible to provide the user as a relatively inexpensive commodity having changed the heat exchange ability of the heat exchanger 3. In such a case, the configuration and the dimensions of the base 6 and the like are not changed, and the configuration is advantageous in terms of cost.

At the front of the wind shielding member 8, an inverted substantially concave locking portion is formed for locking at the rear end and the front side of the rear inclined portion 3b. , So that the wind shielding member 8
However, the structure is such that it is not displaced or deformed in the direction of the arrow a shown in FIG. 1 (B), and no gap is formed between the rear inclined portion 3b and the suction port. The structure is such that the suction air sucked from the port 2 does not pass through without heat exchange, so that the heat exchange efficiency can be prevented from being reduced.

[0017] Further, the upper surface of the locking portion may be attached to the filter.
By holding the filter guide 2b holding the 2a, or a hanging piece hanging down from the filter guide 2b, and the upper part of the rear inclined portion 3b, the wind shielding member 8 is
The structure is such that it is not displaced or deformed in the direction of the arrow b shown in FIG. 1 (B), and no gap is formed between the suction port 2 and the rear inclined portion 3b. This prevents the air sucked from the air from passing without heat exchange, thereby preventing the heat exchange efficiency from being reduced.

Further, the wind shielding member 8 is made of synthetic resin, and as shown in FIG. 2 (A), as one embodiment, the locking portion is provided with a vertical portion which contacts the rear end of the rear inclined portion 3b. The first locking claw 8a is configured to be locked to the front side.
The wind shield 8 and the locking portion are formed integrally with the front end c of the mold 8a at the dividing position of the mold, so that the wind shielding member 8 and the locking portion have a cost-effective configuration. The structure can be integrally molded, and the structure of the mold for integrally molding does not need to be complicated.

The first locking claw 8a is formed over the entire width of the wind shielding member 8 so that the first locking claw 8a can be accurately and firmly locked to the front side of the rear inclined portion 3b. Has become.

Further, the wind shielding member 8 is made of synthetic resin, and as shown in FIG. 2B as another embodiment, the locking portion is formed by a vertical portion which abuts on the rear end of the rear inclined portion 3b. And a second locking claw 8a 'that locks on the front side, and a through hole 8b is provided in the vertical portion facing the second locking claw 8a'.
8b and the second locking claw 8a 'at a split position so that the wind shielding member 8 and the locking portion are integrally formed, so that the wind shielding member is formed as in the case of the first embodiment. The member 8 and the engaging portion can be integrally formed in a cost-effective configuration, and the structure of the mold for integrally forming does not need to be complicated. Since the through hole 8b is closed by being sealed by the seal member 9, the suction air sucked from the suction port 2 does not pass through the through hole 8b without heat exchange.

The second locking claw 8a 'and the through hole
By providing the baffle 8b at substantially the center in the left-right direction of the baffle member 8, the breeze barrier member 8 is prevented from being deformed by expansion due to heat or the like, and no gap is formed between the baffle member 8 and the rear inclined portion 3b. Thus, the structure can be effectively prevented.

Further, the second locking claw 8a 'and the through hole
By providing a plurality of 8b at substantially equal intervals in the left-right direction of the wind shield member 8, the wind shield member 8 is prevented from being deformed by expansion due to heat, and a gap is formed between the wind shield member 8 and the rear inclined portion 3b. The structure is such that it can be more effectively prevented from occurring.

With the above configuration, FIG. 1 (A) and FIG.
As shown in FIG. 2 (B) and FIG. 2 (A) and FIG. 2 (B), when the heat exchanger 3 from which the downward inclined portion 3c has been removed is installed, a front portion of the wind shielding member 8 is provided. , The rear inclined portion
An inverted substantially concave locking portion for locking the rear end and the front side of the locking portion 3b is formed. The locking portion holds the rear inclined portion 3b and holds the upper surface of the locking portion with the filter 2a. The windshield member 8 is displaced or deformed by being sandwiched between the filter guide 2b or the hanging piece hanging down from the filter guide 2b and the upper part of the rear inclined portion 3b.
