Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-ceiling type air conditioner for performing air conditioning such as cooling and heating, and more particularly to an air flow from a blower of an indoor unit coming into contact with a heat exchanger. The present invention relates to an air conditioner with reduced vibration and noise.

[0002]

2. Description of the Related Art Among air conditioners used for air conditioning such as cooling and heating, there is a ceiling embedded type air conditioner in which an indoor unit is embedded in a ceiling. In a ceiling-embedded air conditioner, a blower and an indoor heat exchanger are built in a unit casing of an indoor unit. The indoor heat exchanger has a linear arrangement section and a curved arrangement section, and is arranged so as to surround the blower.
Heat exchange fins are attached to the heat exchange tubes of the indoor heat exchanger,
The heat exchange efficiency is increased by increasing the contact area with the air flow.

[0003] In the linear arrangement portion of the heat exchanger 1, FIG.
As shown in FIG. 0, the air flow a from the blower 2 is
The heat exchange fins 3 contact the heat exchange fins 3 at an angle θ, and the resistance of the air flow a to the heat exchange fins 3 causes the heat exchange fins 3 to vibrate, thereby causing noise.

Further, when the air flow a flows into the heat exchange fins 3 at an acute angle, a vortex is generated on the back side of the heat exchange fins 3 due to the entrainment of the air flow a, and this vortex generates noise and poses a problem.

The vibration caused by the collision of the air flow a with the heat exchange fin 3 generally increases almost in proportion to the inflow angle θ of the air flow a into the heat exchange fin 3. Therefore, in the heat exchange fins 3 provided on the downstream side in the rotation direction of the blower 13 in the linear array portion of the heat exchanger 1, the inflow angle θ of the airflow a into the heat exchange fins 3 increases, so that vibration and noise are generated. Was likely to be noticeable.

As a measure for preventing vibration and noise, FIG.
As shown in FIG. 1, there is a type in which a flat wind direction guide plate 4 protrudes from the tip of the heat exchange fin 3. The wind direction guide plate 4 guides the air flow a to the heat exchange fins 3 smoothly and smoothly, reduces the inflow angle of the air flow a into the heat exchange fins 3, and reduces vibration and noise of the heat exchange fins 3. Function as

[0007] In a conventional air conditioner having a sufficient gap space between the heat exchanger 1 and the blower 2, the flat wind direction guide plate 4 is effective. However, at present, air conditioners are being downsized and air conditioning capacity is being improved.

As the size of the air conditioner is reduced, the distance between the blower 2 and the heat exchanger 1 is reduced so that the heat exchange fins are closer to the blower 2, while the air amount a from the blower tends to increase as the cooling and heating capacity is improved. Therefore, the conventional flat wind direction guide plate 4 cannot sufficiently reduce vibration and noise.

Further, in the flat wind direction guide plate 4,
Since the back side of the wind direction guide plate 4 forms an acute angle with the inflow direction of the air flow a, the air flow a from the blower 2 is
As a result, the vortex is generated by the air flow a, and the vortex noise is also generated.

[0010]

In the linear arrangement portion of the heat exchanger 1, the air flow a from the blower 2 flows to the heat exchange fins 3 of the heat exchanger 1, especially at a large inflow angle downstream of the linear arrangement portion. θ, the heat exchange fins 3 vibrate due to the resistance of the air flow a by the heat exchange fins 3, causing noise.

On the other hand, as the air conditioner becomes more compact, the distance between the blower 2 and the heat exchanger 1 becomes narrower, so that the heat exchange fins 3 become closer to the blower 2, and the amount of air from the blower 2 increases as the cooling / heating capacity improves. a also tends to increase. Therefore, in the conventional plate-shaped wind direction guide plate 4, the air flow a easily enters the back side of the wind direction guide plate 4, and a vortex is generated due to the entrainment of the air flow a.

The present invention has been made in view of the above circumstances, and reduces the angle of inflow of the air flow from the blower to the heat exchange fins to reduce the vibration and noise of the heat exchange fins due to the air flow from the blower. It is an object of the present invention to provide an air conditioner in which reduction is achieved.

It is another object of the present invention to provide an air conditioner in which vortex noise caused by entrainment of airflow behind heat exchange fins is reduced.

Still another object of the present invention is to provide an air conditioner in which vortex noise caused by air flow entrainment behind the wind direction guide plate is reduced.

Another object of the present invention is to provide an air conditioner in which vibration and noise of heat exchange fins on the downstream side in the direction of rotation of a blower in a linear array portion of a heat exchanger are reduced, and reliability is improved. To be.
