As shown in FIG. 1, the horizontal plate 2 of the front panel 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. Then, the horizontal plate 2 is rotatably fixed, 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. By doing so, the vertical direction of the conditioned air is controlled at a predetermined angle. As shown in FIG. 2, the vertical plate 4 of the main body air outlet is
It has the same structure as the horizontal plate 2, and the shaft protrusions 4a provided at both longitudinal ends of the vertical plate 4 are connected to the main body air outlet 3.
The boss 4 at the end of the vertical plate is inserted into the engagement hole 3b provided in a.
b is inserted into and engaged with an engagement hole 4d provided in the connecting rod 4c. As shown in the figure, the connecting rod 4c is provided with a protruding portion 4e in a direction perpendicular to its longitudinal direction, and an elongated hole 4f is provided in this portion. on the other hand,
A crank 5a is fixed to the electric motor 5, and a cylindrical shaft 5b projects from the radial end of the crank 5a, and is inserted into and engaged with the elongated hole 4f. The crank 5a and the connecting rod 4c form a reciprocating slider crank mechanism, and the vertical plate 4 is rotated by the reciprocating rocking motion of the connecting rod 4c. With the above structure, the blown air in the horizontal direction can be periodically controlled back and forth, but the air blown in the vertical direction is oriented in a predetermined direction. Purpose of the invention In view of the above-mentioned problems, the purpose of the present invention is to periodically automatically control the blowing air in both the horizontal and vertical directions at the same time. This also allows for the selection of Structure of the invention In order to achieve this object, the present invention provides a crank on the motor shaft for driving the wind direction adjustment plate, a cylindrical shaft protruding from the radial end of the crank, and the wind direction adjustment plate. The connecting rod that is driven in series by the link mechanism is provided with an elongated hole that is perpendicular to its longitudinal direction, and the elongated holes of the connecting rod of the vertical and horizontal wind direction adjustment plates are arranged in a column and are connected to the cylindrical shaft of the crank of the electric motor. This is a blowout air direction adjustment mechanism having a loosely fitted reciprocating slider crank mechanism. DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. FIG. 3 is a perspective view of the wind direction adjustment mechanism according to the present invention. A crank 5a is fixed to the shaft of the electric motor 5, and at the end of the crank on the radial side (the side that performs circular motion),
The cylindrical shaft 5b is integrally formed with the crank 5a and protrudes. On the other hand, the vertical plate 4 and the horizontal plate 2 for adjusting the wind direction have shaft protrusions 4a, 2a on each plate, as in the conventional example.
And bosses 4b, 2b are provided at a predetermined distance from this. A pair of connecting rods 6 and 7 that respectively connect the sets of horizontal plates 2 and vertical plates 4 made up of a plurality of plates have boss holes 6a, which can be loosely fitted into the bosses 2b and 4b of the horizontal plates 2 and vertical plates 4, respectively. 7a is provided, and the boss hole 6a and the bosses 2b, 7a and 4b are in an engaging relationship and the connecting rods 6, 7 reciprocate and swing, thereby causing each plate to rotate. One end of the connecting rods 6, 7 has elongated holes 6b, 7b in a direction perpendicular to the longitudinal direction and parallel to the rotational axis direction of each plate. The cylindrical shaft 5b provided on the crank 5a of the motor shaft is connected to the elongated holes 6b, 7b of each connecting rod 6, 7.
Insert and engage the air conditioner and place it on the outlet of the air conditioner. In this structure, when the electric motor 5 rotates, the crank 5a rotates, and the cylindrical shaft 5b moves circumferentially. The elongated holes 6b, 7b of the connecting rods 6, 7 and the cylindrical shaft 5b form a reciprocating slider crank mechanism as shown in FIG. Rotate. According to the configuration of the present invention, the connecting rods 6 and 7 perform reciprocating rocking motion, but the long holes 6b and 7b of the connecting rods 6 and 7 are only loosely inserted into the cylindrical shaft 5b of the crank 5a. If the length of the cylindrical shaft 5b of the crank 5a is set to a predetermined length, the connecting rods 6 and 7 will not come out of engagement. With the above configuration, it becomes possible to control the external blown air periodically in both the horizontal and vertical directions, and in the present invention, the phases of the connecting rods 6 and 7 of the horizontal plate 2 and the vertical plate 4 are different by 90 degrees. Therefore, when the electric motor rotates, it periodically moves in a circular motion vertically, horizontally, and horizontally with respect to the blowing direction, as shown in the table below. Fourth
