DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner equipped with a heat exchanger and a blower, and more particularly to a discharge port guard attached to a discharge port for discharging air after heat exchange in the heat exchanger. Related to the structure.

[0002]

2. Description of the Related Art In a separation type air conditioner which is an example of a conventional air conditioner, a suction port is formed on the back and side surfaces of a main body case which is a housing forming an outer surface of an outdoor unit main body. The outside air is sucked in by the blower to promote the heat exchange between the air and the circulating refrigerant in the outdoor heat exchanger forming a refrigeration cycle together with the compressor and the heat exchanger of the indoor unit, and discharge the air after the heat exchange. The liquid is discharged from the outlet to the outside of the main body case.

FIG. 4 is a diagram showing an outdoor unit of such a separated type air conditioner. In the figure, reference numeral 1 denotes an outdoor unit main body and 1A denotes a main body case. The discharge port 2 is formed.
Reference numeral 3 denotes a discharge port guard that prevents a person from accidentally putting his / her finger into the inside of the main body 1 to cause injury, or to prevent an object from entering the inside and damaging a blower as a blower. It is attached to outlet 2.

The discharge port guard 3 has a large number of air discharges formed by, for example, concentric ribs 4 provided radially and radial ribs 5 provided radially. It has an opening 6.

[0005]

By the way, in a conventional air conditioner provided with such a discharge port guard, it is better to enlarge these air discharge openings so that air can be efficiently blown out. If the air discharge opening is enlarged, the air blowing efficiency is improved, but there is a problem that a finger or the like easily enters and the safety is reduced.

In order to increase the air discharge opening, the interval between the concentric ribs 4 and the interval between the radiating ribs 5 must be increased. The strength of the exit guard becomes insufficient. When the strength is insufficient, the ejection port guard 3 is depressed and the finger enters the inside of the main body 1 even if the finger is erroneously pressed by the finger.

Therefore, the present invention has been made to solve such problems, and has as its object to provide an air conditioner with high safety and high blowing efficiency.

[0008]

SUMMARY OF THE INVENTION The present invention provides a heat exchanger for exchanging heat between circulating refrigerant and air, and a method for blowing the air to the heat exchanger to exchange air and circulating refrigerant in the heat exchanger. In an air conditioner equipped with a blower that promotes heat exchange, a discharge port for discharging air after heat exchange with the circulating refrigerant to the outside of the housing of the air conditioner, and a concentric circle attached to the discharge port A concentric rib provided in a shape and a discharge port guard having a large number of air discharge openings formed by radially provided radial ribs, and a thin reinforcing rib is added between the radial ribs. Things.

[0011]

In the present invention, a discharge port guard is provided at a discharge port for discharging air after heat exchange with the circulating refrigerant in the heat exchanger to the outside of the housing, and a number of air discharge openings of the discharge port guard are concentric. It is formed of concentric ribs provided in a shape and radial ribs provided in a radial shape. Then, by adding a thin reinforcing rib between the radiating ribs, the air discharge opening is formed to a size that does not allow a finger to enter without increasing the air resistance so much that a finger does not enter the discharge port.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side sectional view of an outdoor unit of a separation type air conditioner which is an example of an air conditioner according to an embodiment of the present invention, and FIG. 2 is a front view thereof. 1 and 2, the same reference numerals as those in FIG. 4 indicate the same or corresponding parts.

In FIG. 1, reference numeral 7 denotes a blower fan. The blower fan 7 sucks outside air from a suction port 20 formed in the back surface 1b and the side surface 1c of the main body case 1A as shown by an arrow, and an indoor unit (not shown). Promotes the heat exchange between the air and the circulating refrigerant in the outdoor heat exchanger 9 that forms a refrigeration cycle together with the heat exchanger and the compressor 8, and discharges the heat-exchanged air from the discharge port 2 to the outside of the main body case 1A. Is discharged. Reference numeral 7a denotes a fan motor, and 10 denotes a casing which forms an air passage for guiding air discharged from the blower fan 7 to the discharge port 2.

On the other hand, a discharge port guard 3A is attached to the discharge port 2 as shown in FIG. 2, and the air discharge opening 6 of the discharge port guard 3A is concentric with the concentric rib 4, the radiation rib 5, and the concentric rib 4. Between the at least one of the ribs 4 and the radiating ribs 5, in this embodiment, the reinforcing ribs 5 a added between the radiating ribs 5 are formed in such a size that a finger cannot enter.

By adding such reinforcing ribs 5a between the radiating ribs 5 to form the respective air discharge openings 6 in a size that does not allow a finger to enter, each air discharge opening 6 has Fingers can be prevented from entering, and safety can be improved. Further, since the strength of the discharge port guard 3A is increased by adding the reinforcing ribs 5a, the discharge port guard 3 is not dented even if it is erroneously pressed with a finger, and the safety is enhanced.

Incidentally, since the reinforcing ribs 5a are thinner than the radial ribs 5 and the concentric ribs 4, even if the reinforcing ribs 5a are added between the radial ribs 5, the air resistance does not increase so much. It has become. Therefore, even when the reinforcing ribs 5a are added between the radiating ribs 5, the blowing efficiency can be improved and the safety can be improved.

In the above description, the case in which the reinforcing ribs 5a are added between the radial ribs 5 has been described. However, the present invention is not limited to this. A number of concentric ribs for reinforcement may be provided.

In the above description, the air discharge opening 6 of the discharge port guard 3A has the concentric rib 4 and the radiation rib 5
However, the present invention is not limited to this, and the air discharge opening 6 may be formed by horizontal ribs 10 and vertical ribs 11 as shown in FIG.

In this case, too, the thin reinforcing ribs 11 are provided between at least one of the horizontal ribs 10 or the vertical ribs 11 and only between the vertical ribs 11 in FIG.
By adding “a”, the blowing efficiency can be improved, and each air discharge opening 6 can be formed in a size that does not allow a finger to enter, so that safety can be improved.

[0023]

As described above, according to the present invention, a thin reinforcing rib is added between the radial ribs forming a large number of air discharge openings of the discharge port guard provided at the discharge port.
The blowing efficiency can be improved, and a finger can be prevented from entering the discharge port, so that safety can be improved.
