Industrial Application Field The present invention relates to a structure of a conditioned air blowing part of an air conditioner,
In particular, the present invention relates to a wind direction adjusting device that uses an electric motor to automatically and periodically control the blowing direction in a distributed manner in the horizontal and vertical directions. Conventional Mechanisms and Their Problems When operating an air conditioner, the indoor temperature distribution is often controlled uniformly by periodically changing the blowing direction of conditioned air horizontally or vertically. Conventionally, as shown in FIG. 1, the wind direction adjustment mechanism includes a plurality of vertical wind direction adjustment plates (hereinafter referred to as horizontal plates) 2 disposed on a front panel 1a provided on a front panel 1 of an air conditioner. It is composed of a plurality of horizontal wind direction adjustment plates (hereinafter referred to as vertical plates) 4 arranged at a main body outlet 3a provided in the main body 3. As shown in FIG. 2, the horizontal plate 2 of the front panel 1 is provided with concentric shaft protrusions 2a at both ends in the longitudinal direction, and these are inserted into the left and right engagement holes 1b provided in the front panel air outlet 1a. By making the horizontal plate 2 freely rotatable, the boss 2b provided at the end of the horizontal plate 2 is inserted into the engagement hole 2d provided in the connecting rod 2c, and the horizontal plate 2 is rotated in a series. , the vertical blowing direction of conditioned air is controlled at a predetermined angle. The vertical plate 4 of the main body 3 has a structure similar to that of the horizontal plate 2, as shown in FIG. The bosses 4b provided at the ends are inserted into and engaged with the engagement holes 3b provided in the main body outlet 3a and the engagement holes provided in the connecting rod 4c, respectively. Connecting rod 4
As shown in the figure, part c has a protruding part 4e in a direction perpendicular to its longitudinal direction, and a long hole 4f is provided in this part. On the other hand, a rotor 5a extending in the radial direction is fixed to the rotating shaft of an electric motor 5 that rotates the vertical plate 4 periodically, and the rotor 5a is inserted into the elongated hole 4f of the connecting rod 4c at the tip thereof and can be freely moved. It is provided with a possible shaft-like projection 5b. With this structure, when the motor shaft rotates, the shaft-like protrusion 5b of the rotor 5a moves in a specific circle, while the connecting rod 4c has a long hole provided therein into which the shaft-like protrusion 5b of the rotor 5a is inserted. 4
Due to the action of f, it makes a reciprocating rocking motion in the lateral direction. When the connecting rod 4c performs a reciprocating rocking motion, the boss 4b of the vertical plate 4 is reciprocated, and the vertical plate 4 periodically rotates, thereby periodically blowing out the conditioned air in the horizontal direction. Automatically controlled.
Furthermore, by stopping the rotation of the electric motor at a predetermined rotational position of the vertical plate 4, it is also possible to maintain the horizontal blowing direction of the conditioned air at a predetermined angle. In the above-mentioned conventional examples, periodic and automatic control of the blowing direction of conditioned air is limited to either the horizontal or vertical direction.
The other directions were controlled manually, and it was impossible to make the blowout distribution inside the room uniform both horizontally and vertically. Purpose of the Invention In view of the above-mentioned problems, the present invention makes it possible to periodically and automatically control the blowing air in both horizontal and vertical directions at the same time, and it is also possible to select a specific blowing direction as before. The object of the present invention is to provide a wind direction adjustment device that has a wind direction adjustment device. Structure of the Invention In order to achieve the above object, the present invention provides a connecting rod that sequentially drives a plurality of horizontal and vertical plates for adjusting the wind direction that can change and control the air blowing direction, and a connecting rod that rotates from both axial end faces. a double-shaft type electric motor with a protruding shaft; and a reciprocating slider crank mechanism disposed between each of the rotating shafts and the connecting rod to convert rotational motion of the rotating shaft into linear swinging reciprocating motion of each of the connecting rods. The reciprocating slider crank mechanism includes a rotor that is attached to each rotating shaft so that its mounting angle around the shaft center can be adjusted and has a shaft-like projection at the tip, and a rotor that is formed on each connecting rod and has a shaft-like projection on its tip. It is composed of long holes into which projections are slidably inserted. DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the drawings. FIG. 4 is a perspective view of a mechanical part of the wind direction adjusting device according to the present invention. Rotors 7 and 8 for the horizontal plate 2 and vertical plate 4 for adjusting wind direction are inserted and fixed to both shafts of the double-shaft electric motor 6 by screws 7a and 8a, respectively. Both rotors 7 and 8 are integrally formed with shaft-like protrusions 7b and 8b at specific radial positions, as shown in the figure. On the other hand, the horizontal plate 2 and the vertical plate 4 for adjusting the wind direction have rotating shafts 2a and 4a, and bosses 2b and 4b that engage the connecting rods 9 and 10. Connecting rods 9, 10
are for sequentially rotating a plurality of horizontal plates 2 and vertical plates 4, respectively, and the engagement bosses 2b, 4b
It is equipped with engagement holes 9a and 10a for inserting the
The connecting rods 9, 10 have shaft-like protrusions 7b, 7b of the rotors 7, 8 at one end thereof in a direction perpendicular to the longitudinal direction thereof.
It has elongated holes 9a and 10a into which the slider 8b can be inserted and moved freely. When the horizontal plate 2 and the vertical plate 4 for adjusting the wind direction rotate, the respective connecting rods 9 and 10 perform a reciprocating linear movement in the longitudinal direction, but also perform a slight oscillating movement in the orthogonal direction. Axial projections 7 of rotors 7 and 8
b, 8b are long holes 9b, 10b of connecting rods 9, 10
Since the connecting rods 9 and 10 are inserted into the connecting rods 9 and 10, the swinging momentum of the connecting rods 9 and 10 is absorbed. At this time, the shaft-shaped protrusions 7 of the rotors 7 and 8 are also
b, 8b and long hole portions 9b, 10b of connecting rods 9, 10
The engagement with the holder is permanent. In such a structure, when the electric motor 6 rotates,
shaft-shaped protrusions 7b of rotors 7 and 8 fixed to both shafts;
8b makes a circular motion. This circular motion is caused by the connecting rod 9,
When the shaft-like protrusions 7b, 8b move through the long holes 9b, 10b provided in the connecting rods 9, 10, a reciprocating slider crank mechanism is formed, and the connecting rods 9, 10 reciprocate. As a result, the connecting rods 9 and 10 displace the ends of the horizontal plate 2 and the vertical plate 4 for adjusting the wind direction, so that
The horizontal plate 2 and the vertical plate 4 rotate periodically. Fifth
Figures a to d show the relative positional relationship between the rotational positions of the rotors 7 and 8 and the connecting rods 9 and 10. Also, the rotors 7 and 8 are attached to the motor shaft with screws 7a and 8.
Since the rotors 7 and 8 are fixed by a, the relative angle between the rotors 7 and 8 on the horizontal plate 2 and the vertical plate 4 can be adjusted arbitrarily by rotating the rotors 7 and 8 around their respective axes and adjusting the mounting angle. becomes possible. Tables 1 to 3
As shown in the table, the position of the rotation angle of the motor shaft is 0°.

Assuming [Table] and determining the fixed angle of the rotor so that the horizontal and vertical plates are positioned as shown in Tables 1 to 3 at this position, different periodic motion forms of the blown air can be obtained. It will be done. In other words, Tables 1 and 2 cross the air outlet diagonally across the direction going straight from the air outlet 1a (6th table).
Figures a and b), Table 3 shows a circular movement around the outlet 1a (shown in Figure 6c). Conventionally, blowing air was controlled periodically and automatically only in one direction, either horizontally or vertically, but as in the above embodiment, a double-shaft electric motor is provided in the wind direction adjustment mechanism. This makes it possible to control the blowing direction in both directions. Moreover, the rotor that controls the rotational movement of the horizontal and vertical plates for adjusting the wind direction is fixed to the motor shaft with screws, and the fixed position of the rotor around the motor shaft is different for the horizontal and vertical plates. By doing so, it is possible to select the transition form of the blown air.
Furthermore, since the electric motor between both shafts is disposed between the horizontal plate and the vertical plate, and the entire reciprocating slider crank mechanism is housed between the rotating shafts 2b and 4b of the horizontal plate and the vertical plate, the entire wind direction adjustment mechanism can be made small. It has the advantage of being scalable. Effects of the Invention As described above, the wind direction adjusting device according to the present invention has the following effects. (1) A simple reciprocating slider crank mechanism that converts rotational motion into reciprocating rocking motion is installed, and the connecting rods of the horizontal and vertical plates are simultaneously moved in a linear rocking and reciprocating motion. Control can be performed automatically in both horizontal and vertical directions at the same time. (2) The electric motor that drives the horizontal and vertical plates for wind direction adjustment is single, and by using this as a dual-actual type, there is no need for other motion transmission mechanisms and elements such as gears and belts, and the mechanism is simple. Simplified. (3) By using both rotating shafts of the electric motor, the electric motor can be disposed between the horizontal plate and the vertical plate for adjusting the wind direction, and the product can be made smaller. (4) In the two reciprocating slider crank mechanisms that connect both rotating shafts and the connecting rods of the horizontal and vertical plates, vertical and horizontal Each wind direction can be adjusted independently.
