2. Description of the Related Art The above-mentioned wall-mounted air conditioner has a blow-out passage formed by providing two horizontal guide blades at an outlet thereof, and rotates the horizontal guide blades around a blade axis during a cooling operation. By moving the air outlet, the blowing direction of the cool air from the outlet is periodically changed. At this time, by rotating the two horizontal guide blades at a fixed angle, a uniform blowing opening is ensured both at the time of blowing in the horizontal direction and at the time of blowing downward, and the indoor The temperature distribution can be improved (see, for example, JP-A-6-159790).

[0003]

However, in the above-mentioned conventional wall-mounted air conditioner, the angle between the two horizontal guide vanes is fixed at the throttle angle, that is, the angle at which the width of the outlet passage becomes narrower in the outlet direction. In such a case, when blowing in the horizontal direction, cold air can be blown to a distant place in the room, but when blowing down, the blown cold air directly hits the user, so the temperature distribution is improved. On the contrary, there has been a problem that the use comfort is impaired.
On the other hand, if the angle between the two horizontal guide blades is a wide angle, that is, the angle at which the blowing passage becomes wider toward the blowing direction, and is constant, the cool air is expanded at the time of blowing downward. This can avoid the above-mentioned problem that it directly hits the user and reduces the comfort of use, but on the other hand, when blowing out in the horizontal direction, it is not possible to blow cold air to a distant place in the room, and the room temperature distribution There has been a problem that improvement cannot be achieved.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and has as its object to improve the temperature distribution in a room and thereby to improve the comfort of use. An object of the present invention is to provide a shape air conditioner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the wall-mounted air conditioner of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partial sectional view showing a main part of the wall-mounted air conditioner. The reference numeral 1 shown in FIG. 1 denotes a main unit casing of an indoor unit installed at a high position in a wall surface of a room, and a fan 4 is provided in the main unit casing 1. And in front of the fan 4, that is, to the left in FIG.
An indoor heat exchanger (not shown) is arranged, and a suction port (not shown) is provided in a main body casing 1 corresponding to the front side thereof.
Is open. In addition, a scroll portion 5 that is smoothly inclined from the back side of the fan 4 to the bottom surface of the main body casing 1 is formed.
An outlet 2 facing obliquely downward is open. The outlet 2 is provided with a pair of horizontal guide blades, that is, an upper flap 11 and a lower flap 12. The upper flap 11 and the lower flap 12 are respectively provided on a blade shaft provided on the opposite side of the blow-out side. , That is, the upper flap shaft 13
And the blow-out side rotates about the lower flap shaft 14. And the above upper flap 1
1 and the lower flap 12, the air-conditioning air outlet passage 1
5 are formed. In FIG. 1, reference numeral 6 denotes a drain pan disposed below the indoor heat exchanger.

In the wall-mounted air conditioner, the indoor heat exchanger functions as an evaporator of the refrigerant circuit and the fan 4 is driven to rotate to perform the cooling operation. That is,
The indoor air sucked from the inlet is cooled by exchanging heat with the indoor heat exchanger, and the cooled air-conditioned air is sent along the scroll portion 5 and blown out from the outlet 2 as cool air. The blowing direction is such that the horizontal blowing and the downward blowing are alternately repeated by the rotation of the upper flap 11 and the lower flap 12. On the other hand, if the indoor heat exchanger functions as a condenser of the refrigerant circuit and the fan 4 is driven to rotate, the heating operation can be performed.

Next, the rotation of the upper flap 11 and the lower flap 12 during the cooling operation will be described. 1 and 2 are partial cross-sectional views showing each state or a state at a passing point, and FIG. 3 is a graph showing the movement of the upper flap 11 and the movement of the lower flap 12 by broken lines. In this graph, the movable range of the upper flap 11 is A
-B, the movable range of the lower flap 12 is indicated by CD. First, FIG. 1A shows a state of the upper flap 11 and the lower flap 12 at the time of blowing in the horizontal direction. Both flaps 11 and 12 are located at the upper limit positions A and C of the movable range, respectively, and the outlet passage 15 is formed so as to become narrower toward the outlet side of the cool air. Therefore, at this time, the cool air is blown by the squeezed air, and the conditioned air can be supplied indoors to a location distant from the installation position of the indoor unit. This state is changed at time T as shown in FIG.
It is maintained between ₁ through T _2. Then from the time _{T 2,} the flaps 11, 12 starts a downward rotation. And FIG. 2 (a), the flaps 1 at time _{T 3}

Is located at the lower limit position B of the movable range, while the lower flap 1
No. 2 has not yet reached the lower limit position D and is at an intermediate position and continues downward rotation. Therefore outlet passage 15 will be substantially parallel to the vicinity of the time T _3. Only the lower flap 12 continues to rotate further from time T _3. The lower flap 12 at time T ₄ reaches the lower limit position D, the state at the time of balloon downward. At this time, as described above, the two flaps 11 and 12 are at the lower limit positions B and D of the movable range, respectively, and as shown in FIG. 1B, the blowing passage 15 is formed so as to become wider toward the blowing side of the cool air. ing. Therefore, at this time, the cool air is blown wide, and the cool air can be spread and supplied to a user located below. And this state is maintained between times T ₄ through T ₅ as shown in FIG. Then from the time _{T 5,} the flaps 11 and 12 to start an upward rotation. FIG. 2B shows the time T. The above both flaps 1
1 and 12 are shown. At this time, the upper flap 11
Is located at the upper limit position A of the movable range, while the lower flap 1
No. 2 has not yet reached the upper limit position C, and is at an intermediate position and continues to rotate upward. Therefore outlet passage 15 will be substantially parallel to the vicinity of the time T _6. Only the lower flap 12 continues to rotate further from time T _6. The lower flap 12 at time T ₇ returns to the state at the time of balloon reaches the upper limit position C in the horizontal direction shown in FIG. 1 (a), subsequently repeated.

In the above-described wall-mounted air conditioner, the blowing of cold air in the horizontal direction and the blowing of cold air in the downward direction are alternately repeated during the cooling operation, and the blowing passage 15 is blown in the blowing direction during the blowing in the horizontal direction. In the case of downward blowing, the blowing passage 15 is formed wider in the blowing direction to achieve wide blowing. Therefore, when blowing out in the horizontal direction, supply conditioned air to a place distant from the indoor unit,
The indoor temperature distribution can be improved. In addition, since the air blows downward at the time of wide blowing, it is possible to prevent the cool air from directly hitting the user and obstructing the user's comfort, thereby ensuring the improvement of the use comfort by improving the temperature distribution. be able to. Also, between the time of blowing in the horizontal direction and the time of blowing downward, the blowing passage 1
The width of the outlet side of No. 5 is smoothly changed, and is substantially parallel in the middle. Therefore, the change in the state of blowing the cold air becomes smooth, and the above-mentioned comfort can be more reliably improved. Further, the upper and lower flaps 11 and 12 have upper and lower flap shafts 13 and 14 on opposite sides of the blow-out side, respectively. Is changing. Therefore, the configuration can be simplified.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be variously modified and implemented within the scope of the present invention. For example, in the above case, as shown in FIG.
The upper flap 11 with ₃ or time T ₆ to reach the lower limit position B or the upper limit position A above, are rotated only then under the flap 12. This is because, as shown in FIG. 4, at the same time respectively the lower limit position B flaps 11 and 12 at time _{T 4,} D
Substantially may be respectively reach the upper limit position ANC simultaneously reached, and the time T ₇ to.
