Description

[Detailed Description of the Invention] The present invention relates to an electric wind direction grill for air conditioning equipment in which the wind direction grill is electrically oscillated.

In room coolers and other heating and cooling equipment, a wind direction grill is provided at the outlet for cold or hot air so that the direction of the wind can be changed to the desired direction.

In the conventional device, as illustrated in FIG. 1, bushes 3, a, 3b, 3c, etc.
Since the wind direction grills 5a, 5b, 5C...... are simply rotatably attached via the ......, 4a, 4b, 4C......, when changing the wind direction, It was necessary to manually tilt each grill, making the operation complicated.

Furthermore, recently, air conditioning equipment has been devised in which a wind direction grill is electrically driven by a gear motor.

2 and 3 show an example of such a conventional device. In FIG. 2, a pair of upper and lower horizontal frames 6, 7 are shown.
A grille frame 9 consisting of a pair of left and right vertical frames 8 (the other one is not shown) has a shirt 10a extending through the upper plates of the horizontal frames 6 and 7.

10b, IOC... is rotatably supported.

Each of these shafts is provided with a flat wind direction grill 11a.
, 11b, 11c... are fixed.

Further, at the lower end near one side edge (each left edge in FIG. 2) of these wind direction grilles, there is an engagement shaft 12 that projects downward.
a, 12b, 12C... are planted.

The lower ends of these retaining shafts are rotatably inserted into through holes in a connecting plate 13 arranged parallel to the horizontal frames 6 and 7.

A slide plate 15 having an elongated hole 14 is fixed to approximately the center in the longitudinal direction of the connecting plate 13, and the elongated hole is formed in a direction perpendicular to the longitudinal direction of the connecting plate 13.

Reference numeral 16 in the figure is an electric motor that generates an output that is decelerated by a built-in gear mechanism (not shown). installed on.

This slide shaft 18 is slidably inserted into the long hole 14 of the slide plate 15.

In the conventional device configured as described above, when the electric motor 16 is driven, the slide shaft 18 rotates around the rotation axis of the electric motor.

As a result, the slide shaft 18 reciprocates in the elongated hole 14 of the slide plate 15 as shown in FIG. reciprocate in the direction.

As a result, each wind direction grill 11a, 11b, 11
C------- are noshafts 10a, 101) and I, respectively.
Using OC as a fulcrum, a swinging motion is performed at a predetermined period as shown in FIGS. 3A to 3D.

However, such a conventional device has a drawback in that the swing angle of the wind direction grill is constant and cannot be adjusted, and air can only be blown within a fixed range.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an electric wind grill for air conditioning equipment that can blow air over a wide range by adjusting the swing angle of the wind grill, has a simple structure, and does not generate noise.

Hereinafter, an embodiment of the electric wind direction grill for air conditioning equipment according to the present invention will be described with reference to FIG. 4, in which the same parts as in FIG. 2 are denoted by the same reference numerals.

In the conventional example shown in FIG. 2, the rotating shaft 16a of the electric motor 16 and the slide shaft 18 are connected by a single connecting arm 17, but in the present invention, this connecting arm 17 can be bent in the middle. It consists of two connecting arms.

That is, as shown in FIGS. 4 to 6, the connecting arm 17 that connects the rotating shaft 16a of the electric motor 16 and the slide shaft 18 is composed of a first connecting arm 19a and a second connecting arm 19b. Both are fixed by a wing nut 20 so that the legs can be opened freely.

FIG. 5 shows the connecting arm 19a. 19 b and slide shaft 18
The slide shaft 18 is composed of a bolt 21a installed in the second connecting arm 19b, a rotary pipe 21b loosely fitted onto the bolt 21a, a washer 21C, and a nut 21d. There is.

The opening angle θ of the first and second connecting arms 19a and 19b can be adjusted to any desired angle by loosening and adjusting the angle θ.

In the embodiment of the present invention configured as described above, when the electric motor 16 is driven, the slide shaft 18 moves between the first and second
The electric motor 16 rotates around the rotating shaft 16a while maintaining a radial distance determined by the leg opening angle θ of the connecting arms 19a and 19b.

As a result, the connecting plate 13 performs a reciprocating motion to connect each wind direction grill 11a.

11 b, 11 C are shafts 10 a, 10 b,
Perform a swinging motion around 10C.

Therefore, according to this embodiment, by loosening the wing nut 20 and adjusting the opening degree θ of the first and second connecting arms 19a, 19b, the swing angle of each wind direction grill can be adjusted as shown in FIG. It can be freely changed to wide and narrow.

If the distance between the supporting points of the first and second connecting arms 19a and 19b is set to L/2 as shown in FIG. 6, then the connecting arm 19a as shown in FIG.
, 19b and the wind direction grilles 11a and 11b.
, ll and c are the same, so it can be used as a guideline for setting the angle.

As described above, according to the present invention, since the angles of the first connecting arm and the second connecting arm can be adjusted, the swinging range of the wind direction grill can be easily changed, and cool air or warm air can be supplied over a wide range. It can improve the efficiency of heating and cooling.

In addition, the electric wind direction grill of the present invention is simple in construction, has only a slight increase in cost, and generates almost no noise.
