Description

[Detailed Description of the Invention] The present invention relates to an air conditioner in which the air volume is increased by changing the shape of the casing.

In conventional air conditioners, so-called split wall-mounted indoor units that adopt the push-in method, the casing, that is, the part of the casing that surrounds the cross-flow fan, did not have a functional shape. Therefore, it was not possible to increase the air volume.

As shown in FIG. 1, air conditioners generally have a configuration in which a cross-flow fan 2 is provided above a casing 1 having a substantially rectangular cross-section, and a heat exchanger 3 is provided below this cross-flow fan 2. Rare, horizontal fan 2
The shape of the portion of the casing 1 that covers the casing 1 is formed into an angular shape as shown in the figure.

Therefore, the suction port 4 can only be formed in the upper part of the flat front surface of the casing 1, and the suction area cannot be increased.The space inside the casing 1 is limited, and a large-diameter cross-flow fan cannot be used. Since it is not possible to provide a conventional air conditioner, it is not possible to increase the air volume, and in order to increase the air volume, the entire air conditioner must be made larger.

This idea was created in view of the above circumstances.
The purpose of this is to form the casing of the air conditioner into an arc shape that follows the outer circumference of the crossflow fan from the front to the top, and to form an inlet from the middle of the front to the middle of the top. To provide an air conditioner with a simple configuration capable of increasing air volume.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIG. 2 and subsequent drawings.

10 is an air conditioner using a push-in method in a split wall-mounted indoor unit. 11 is a casing, with a suction port 17 at the upper part of the indoor side and an outlet 1 at the lower part.
Further, inside the casing 11, a cross-flow fan 12 is arranged inside the suction port 17, and a heat exchanger 13 is arranged inside the blow-off port 16 below the cross-flow fan 12.

The heat exchanger 13 is installed vertically within the casing 11 in a slightly inclined state so as not to take up too much width.
This causes the inside of the casing 11 to move upward to the suction side 14.
However, a blowout side 15 is formed in the lower part. On the other hand, at the front of the casing 11 on the outlet side 15, that is, at the lower part of the front of the casing 11, an outlet 16 is formed with a current plate.

In such a configuration, the casing 11 is formed in an arc shape along the outer circumference of the crossflow fan 12 from the front surface to the top surface (a in FIG. 2), and the suction port 17 is formed from the middle of the front surface to the middle of the top surface. A filter (not shown) is removably attached to this suction port 17. Furthermore, a guide body 20 is provided that extends from the middle of the front surface toward the lower center of the crossflow fan 12 in the upper part of the interior.

Thus, the air conditioner 10 configured as described above draws air from the upper suction port 17 by the crossflow fan 12 through the heat exchanger 13 to the lower blowout port 17.
From 6, it is blown out as cold or warm air. and,
A suction port 17 is formed from the middle of the front surface of the casing 11 to the middle of the upper surface, and a guide body 20 is provided that extends from the middle of the front surface toward the lower center of the cross-flow fan 12 located above the inside, thereby increasing the suction area and increasing the air volume. can be increased. Moreover, since the suction port is formed in an arc shape along the outer periphery of the crossflow fan 12 from the front surface to the top surface of the casing 11, the shape of the casing is not a square shape as in the conventional case, so the casing itself can be made smaller. be able to.

As a result, in the air conditioner of the present invention, compared to the conventional one, the number of revolutions of the cross-flow fan is lowered to reduce noise, or the diameter of the cross-flow fan is made smaller. By narrowing the depth dimension of the main body, it is possible to reduce the size of the main body itself.

Further, since the upper part of the suction port 17 is formed to bulge in an arc shape, the filter can be attached and removed from the suction port 17 with great ease, and the design can also bring out a novelty.

Incidentally, the arcuate portion a in the above embodiment may be formed to protrude from the front surface of the casing 11 as shown in FIG. 3 (a' in FIG. 3); in this case, the arcuate portion a' Since the space inside 11 becomes wider, a large-diameter cross-flow fan 12' can be installed, thereby further increasing the air volume.

In summary, according to the present invention, the suction port is formed from the middle of the front surface of the casing to the middle of the top surface,
By providing a guide body that extends from the middle of the front surface toward the lower center of the crossflow fan in the upper part of the interior, the suction area can be expanded and the air volume can be increased. Moreover, since the suction port is formed in an arc shape along the outer circumference of the crossflow fan from the front surface to the top surface of the casing, the shape of the casing is not rectangular as in the past, so the casing itself can be made smaller. Can be done.

As a result, in the air conditioner of the present invention, compared to the conventional one, the number of revolutions of the cross-flow fan is lowered to reduce noise, or the diameter of the cross-flow fan is made smaller. By narrowing the depth dimension of the main body, it is possible to reduce the size of the main body itself.

Furthermore, since the air conditioner of the present invention has a simple configuration, it can be provided at low cost.
