Abstract

PROBLEM TO BE SOLVED: To improve ventilating efficiently as well as ventilating performance by a method wherein a connecting crossbar is provided so as to be slanted more than a right angle with respect to the center axis of left and right wind direction changing vanes to move the connecting crossbar, positioned in an air guider, in parallel to the wind flow. SOLUTION: A plurality of sheets of left and right vanes 2 for changing the direction of wind leftward and rightward are provided in the opening of a diffusing grille for the main body of an air conditioner while connecting projections 2a are formed integrally with the left and right vanes 2 so as to be slanted with respect to the center axis of the left and right vanes 2. Then, a connecting crossbar 1 is provided so as to keep a right angle with respect to the axis of the connecting projections 2a. According to this method, the connecting crossbar 1 is slanted more than a right angle with respect to the center of axis of the left and right vanes 2. In this case, the positional angle of the connecting crossbar 1 becomes parallel to the angle of wind direction whereby the interference to ventilation can be reduced and the ventilating performance of the air conditioner can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction changing device for an air conditioner in which the direction of wind blown from an indoor unit is changed by blades.

[0002]

2. Description of the Related Art A conventional wind direction changing device for an air conditioner has a connecting projection 2a integrally formed in parallel with the axial center of a left / right changing blade 2 as shown in FIGS. 2
A connecting member 1 is provided at a right angle to the axis a.
The connecting member 1 is provided at right angles to the center of the shaft.

In the above configuration, when the wind 3 blown out from the blower fan 6 is blown through the air guider 5 as shown in FIG. 1, the wind direction is changed by the left / right changing blades 2 and blown into the room. .

[0004]

However, in the above-described conventional configuration, the connecting member 1 located inside the air guider 5 is not parallel to the flow angle of the wind 3 but at an angle having an inclination. Therefore, there is a problem that the resistance of the wind 3 is generated and the ventilation performance is hindered.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a wind direction changing device which can reduce the hindrance of the ventilation performance and has a high blowing efficiency.

[0006]

According to the present invention, a connecting member is provided so as to be inclined from a right angle with respect to the axial center of the left / right changing blade.

[0007] With the above structure, the connecting member located inside the air guider is parallel to the flow angle of the wind, so that the air blowing efficiency is improved and the ventilation performance can be improved.

[0008]

According to the first aspect of the present invention, a plurality of left and right blades for changing the wind direction to the left and right are provided at the mouth of the blowout grill, and a connecting projection inclined with respect to the axial center of the left and right blades is provided. The connecting members are formed integrally with the left and right blades and provided with connecting members at right angles to the axis of the connecting convex, so that the connecting members are inclined at right angles to the center of the left and right blade axes.
Thus, the position angle of the connecting member is parallel to the flow angle of the wind, so that the obstruction of the ventilation can be reduced.

According to a second aspect of the present invention, the shape of the connecting member is made smaller at the windward end surface than at the windward end surface.
The flow of the wind can be smooth.

[0010]

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

(Embodiment 1) In FIG. 1, a connecting projection 2a inclined with respect to the axial center of the left / right changing blade 2 is integrally formed, and a connecting member 1 is provided at right angles to the axis of the connecting projection 2a. I have.

FIG. 2 shows a left and right wind direction changing device incorporated in the blower grill of the air conditioner main body of the present embodiment. A wind 3 blown out from a blower fan 6 is blown out through an air guider 5. Sometimes, the wind direction is changed by the left and right changing blades 2 and the air is blown into the room.

In the above configuration, since the position angle of the connecting member 1 is parallel to the flow angle of the wind 3, the wind 3
Resistance can be reduced.

In the above embodiment, the position of the connecting member 1 is adjusted to the flow direction of the wind 3, but the shape of the connecting member 1 is further changed with respect to the end face of the windward portion 1b as shown in FIGS. The wind 3 can be made to flow smoothly by reducing the end face of 1c.

[0015]

As is apparent from the above embodiment, the invention according to claim 1 is characterized in that a connecting projection inclined with respect to the axial center of the left / right changing blade is formed integrally with the left / right changing blade. By providing a connecting member at right angles to the connecting convex shaft,
The connecting member is inclined at a right angle with respect to the center of the left and right blade axes. According to this configuration, the position angle of the connecting member is parallel to the flow angle of the wind, so that the obstruction of the ventilation can be reduced, and the ventilation performance can be reduced. The effect of improving is achieved.

According to the second aspect of the present invention, the end face of the leeward portion is made smaller than the end face of the leeward portion of the connecting member. According to this configuration, wind can smoothly flow on the surface of the connecting member, This has the effect of lowering the wind noise.
