Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner that performs cooling and heating by blowing out an air conditioning flow.

BACKGROUND ART A conventional air conditioner of this type had a structure as shown in FIG. That is, the air-conditioning flow coming out of the cross flow fan 1 is deflected in the vertical direction by the upper and lower deflection blades 2 and in the left and right direction by the left and right deflection blades 3, and is blown out into any living space.

Problems to be Solved by the Invention However, this type of structure has the disadvantage that although it can deflect sufficiently in the vertical direction (θ = approximately 60°), it can only deflect approximately 20° in the horizontal direction. There were many living spaces where the water could not reach, causing problems with comfort.

Therefore, the present invention aims to improve comfort by providing a structure that can achieve deflection of approximately 60 degrees in the left and right directions.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems includes a day user part provided on the downstream side of the cross flow fan, and a day user part arranged in the day user part and substantially perpendicular to the flow. A group of left and right blades that rotate around a left and right blade axis, have a plurality of blades having substantially the same height as the day user, and have an interval between the blades that is equal to or less than the width of the blade in the flow direction; Two opposing upper and lower guide walls having a gradually expanding shape that are continuously provided from the downstream end, and which are provided between the upper and lower guide walls and rotate around a vertical rotation axis that is substantially perpendicular to the left and right blade axes, The device is configured to have a vertical deflection member that deflects the flow vertically, and two opposing left and right guide walls that gradually expand in a direction substantially perpendicular to the upper and lower guide walls and form an air outlet together with the upper and lower guide walls. It is something.

Effects The present invention has the above-mentioned configuration, and is formed so that it is vertically restrained so that no flow occurs from the gap because it has approximately the same height as the day user part, and is arranged at intervals that are approximately the same as or smaller than the width. By tilting the left and right blade groups, the flow passing between the left and right blades is sufficiently deflected in the direction of the blade inclination by the guiding action of the blades, and as a result, this flow interferes with the left and right guide walls. This increases the deflection angle by adhering to the left and right guide walls, thereby ensuring a sufficient deflection angle.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In Figures 1 to 3, 4 is the air conditioner main body, 5 is the heat exchanger, 6 is the cross flow fan, and 7 is the air conditioner body.
is a day user section provided on the downstream side of the cross flow fan 6, in which left and right blade groups 9 are arranged. As shown in FIG. 2, the left and right blade groups 9 have a height H _L that is almost the same as the height _HD of the day user portion, and are restrained vertically by the day user 7. Further, as shown in FIG. 3, the interval P between the left and right blade groups 9 is arranged to be equal to or smaller than the width W in the flow direction. Further, the left and right blade groups 9 are arranged in a line and are provided with a connecting member 10 for rotation in the same manner. In this case, the shapes of the left and right blades are shown as flat plates in the figure, but they may also be arcuate blades, and the deflection is larger in this case. Furthermore, on the downstream side of the day user section 7 shown in FIG. Vertical deflection blade 1 rotating around
4 is placed. Also, as shown in Figure 3,
Left and right guide walls 15 and 16 (arc-shaped in the figure, but a planar shape is also effective) that are gradually enlarged substantially perpendicular to the upper and lower guide walls 11 and 12 are provided. and left and right guide wall 1
5 and 16 form a rectangular taper-shaped air outlet 17.

In the above configuration, when the left and right blade groups 9 are in the position shown by the solid line in FIG. 3, the flow blows out to the front, but
When tilted as shown by the broken line, the flow F ₁ that has passed between the blades is in a form in which the blade group 9 is restrained by the day user part 7, and the interval P is the width W in the flow direction.
Because it is arranged at the same level or lower than that, it is sufficiently deflected by the guiding action of the blades.
A deflection angle α ₁ approximately equal to the inclination of the blade group 9 is obtained. As a result, the flow interferes with the left and right guide walls 15, adheres to the wall surface, and is expanded to a deflection angle of α ₂ , resulting in a sufficient deflection angle of approximately 60°.

In addition, by tilting the upper and lower deflection blades 14,
The flow adheres to the upper and lower guide walls 11 or 12 and is deflected at a wide angle. That is, by tilting the left and right blade groups 9, the flow can be deflected left and right, and by tilting the vertical deflection blades 14, the flow can be deflected vertically over a wide angle, and by combining these two, the flow can be deflected horizontally and vertically. It becomes possible to blow out the flow in any direction. In addition, the upper and lower and left and right guide walls 11, 1
Since the air outlet 17 is formed by 2, 15, and 16, the above effect can be obtained with almost no change in space from the conventional one. In addition, when the blade shape is made into an arc shape and curved in the direction that the flow follows the guide walls 15 and 16 as shown in FIG. 9a, more deflection angles can be obtained compared to straight blades.

Effects of the Invention As described above, the air conditioner of the present invention provides the following effects.

(1) Place the left and right blades in the day user section, make the height of this blade almost the same as the height of the day user part, arrange the spacing between the blades to be equal to or less than the width of the blades, and install the left and right guide walls on the downstream side. Because of the configuration, the deflection was sufficient due to the guide action of the blades, but it interfered with the left and right guide walls installed on the downstream side, and the flow adhered to the wall surface, resulting in wide-angle left and right deflection. is obtained.

(2) By forming a rectangular winding outlet with the upper and lower and left and right guide walls, it is possible to deflect the flow at a wide angle vertically and horizontally in almost the same space as conventional ones.

(3) Since the left and right blade groups are arranged on the upstream side and the upper and lower deflection members on the downstream side, only the upper and lower deflection members are visible from the outside, resulting in a simple appearance.
