Description

Outdoor unit of air-conditioner {OUTDOOR UNIT OF AN AIR CONDITIONER}

The present invention relates to an air conditioner, and more particularly to a fan guard of a separate air conditioner outdoor unit.

An air conditioner that cools a room using a cooling cycle liquefies refrigerant gas compressed in a compressor in a condenser and then evaporates it through an expansion valve. The air conditioner performs a cooling operation by the heat of vaporization of the refrigerant absorbed by vaporization in. The air conditioner is classified into an integrated type in which each component is built into a cabinet according to its configuration type, and a separate type composed of an outdoor unit having an integrated compressor and a condenser, and an indoor unit having an evaporator. In consideration of the separation type is generally used.

1 schematically shows a conventional outdoor unit of such a separate air conditioner. In the drive chamber 2 of the cabinet 1 partitioned by the partition 4, drive products, such as the compressor 5, are installed, and the condenser 6 has an approximately L-shaped condenser 6 in the cabinet 1. A blower (7) is arranged along the side and rear plates of the fan and forms an airflow therein. In the cabinet 1 at the rear and side of the condensation chamber 3, a plurality of air suction holes 1a are formed along the condenser 6, through which the outside air is sucked by the blower 7, and the cabinet at the front side thereof ( In 1), the air discharge port 1b through which the suction air heat exchanged with the condenser 6 is discharged to the outside is formed. In addition, a fan guard 10 having a grill type is installed at the air discharge port 1b of the cabinet 1 to prevent the external exposure of the blower 7, thereby eliminating the risk of injury by the fan 9. The remaining reference numeral 8 is a motor of the blower 7.

Accordingly, a certain gap exists between the propeller fan of the blower 7 (hereinafter, abbreviated as "fan") and the fan guard 10 covering the fan guard 10 due to the gap. When external force is applied), as shown in the imaginary line, the fan guard 10 made of a synthetic resin material is not only very likely to be damaged, but also causes a risk of injury by the fan 9 when the fan is damaged.

The object of the present invention is to provide an outdoor unit of an air conditioner that can suppress the damage of the fan guard by the external force in consideration of the above-mentioned conventional problems.

In order to achieve the above object, an outdoor unit of an air conditioner according to the present invention includes a cabinet having a plurality of air suction holes and an air discharge port facing each other, a compressor installed in a drive chamber of the cabinet, and a condenser chamber of the cabinet. An outdoor unit of an air conditioner having a condenser and a blower, and a fan guard installed at an air outlet of a cabinet, the outer end of the fan guard being in contact with the hub of the fan when an external force is applied to the center of the fan guard. It is characterized in that the tubular reinforcing bar protruding to prevent damage to the fan guard.

Accordingly, the present invention, when an external force is applied to the fan guard, the tubular reinforcement is supported in contact with the body of the fan and the damage as in the prior art is suppressed as much as possible, thereby exhibiting the effect of improving the reliability and safety of the air conditioner and extending the life.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 2, the outdoor unit of the air conditioner according to the present invention is partitioned in the horizontal direction by the partition wall 14 to constitute the drive chamber 12 and the condensation chamber 13. The drive chamber 12 is provided with a driving product such as a compressor 15 for compressing the refrigerant, the condenser chamber 13 is a condenser 16 for liquefying the compressed refrigerant gas by heat exchange with air and for this purpose A blower 17 to be formed is provided.

The condenser 16 is formed in an approximately L shape to improve thermal efficiency and is disposed along the side plate and the rear plate of the cabinet 11, and the blower 17 is disposed in front of the condenser 16. In the cabinet 11 on the side and the rear side of the condensation chamber 13, a plurality of air suction holes 11a for sucking the outside air into the condensation chamber 13 by the blower 17 are appropriately arranged, and the condensing chamber ( In the front cabinet 11 of 13, one large air outlet 11b for discharging the suction air heat-exchanged with the condenser 16 to the outside is formed.

Accordingly, the fan 19 of the blower 17 is exposed to the outside through the air discharge port 11b of the cabinet 11, and the air discharge port 11b of the cabinet 11 may cause injury or the like by the fan 19. In order to prevent the fan-shaped fan guard 20 is installed.

However, in this case, a predetermined interval is formed between the fan 19 and the fan guard 20 of the blower 17 to relatively weaken the strength of the fan guard 20.

Therefore, in the center of the inner surface of the fan guard 20, the tubular reinforcement 21 is formed to extend in a predetermined length so that the front end is close to the front surface of the body 19a of the fan 19 according to the features of the present invention. The extension length of the tubular reinforcement 21 is preferably set as close as possible in a range that does not interfere with the rotation of the fan 19 when the blower 17 is driven, which is the fan guard 20 Are formed together during injection molding.

The tubular reinforcement 21 may be formed of a polygonal tube such as a square tube or a hexagonal tube, but preferably, the body 19a of the fan 19 for improving its strength and stable reinforcement of the fan guard 20. It is formed as a round tube with a diameter slightly smaller than or equal to the diameter. The remaining reference numeral 18 is a motor of the blower 17, and 19b is a wing of the fan 19.

Since the outdoor unit of the air conditioner according to the present invention having such a structural feature is formed in the center of the inner surface of the fan guard 20, the tubular reinforcement stand 21 is formed close to the body 19a of the fan 19, the fan guard Even if an external force is applied to the 20, the damage of the fan guard 20 as in the prior art is effectively prevented. That is, when an external force is applied to the fan guard 20 as shown by the white arrow, the elastic deformation thereof causes the tubular reinforcement 21 to be pushed backwards, whereby the tip of the tubular reinforcement 21 is The fan guard 20 is supported by being in contact with the body 19a of the fan 17 to prevent the fan guard 20 from being damaged.

At this time, since the tubular reinforcement 21 of the present invention has a diameter substantially the same as that of the body 19a of the fan 19, the fan guard is always in contact with the body 19a of the fan 19 even when an external force is applied in any direction. 20) will be protected from external forces.

On the other hand, when the external force applied to the fan guard 20 is removed, the restoring elasticity of the tubular reinforcement 21 is returned to the initial state by the restoring elasticity to release the interference of the fan 19.

As described above, according to the present invention, it is possible to suppress the damage of the fan guard by external force as in the prior art as much as possible, thereby effectively preventing the injury caused by the fan. Therefore, the present invention can improve the reliability and safety of the air conditioner, as well as contribute to extending the life of the outdoor unit.
