Abstract

PURPOSE:To unify the blow-off distribution at the indoor side over both horizontal and vertical directions by a method wherein a slider crank mechanism is provided on an air flow direction adjusting device, connecting rods for a crosswise plate and a lengthwise plate are moved simultaneously by linear reciprocating motion. CONSTITUTION:At the rotation of a motor 6, shaft-shaped protrusions 7b, 8b of rotors 7, 8 fixed on both axes are moved in circular motion. The circular motion causes the free motion of shaft-shaped protrusions 7b, 8b in long hole parts 9b, 10b provided on connecting rods 9, 10. At this time, a reciprocating slider crank mechanism is formed, connecting rods 9, 10 are moved reciprocatory. Thereby, a lateral plate 2, a longitudinal plate 4 are moved periodically in circular motion. By providing a double shaft axes type motor on an air flow direction adjusting mechanism, the blow-off direction control is enabled over both directions. The rotor causing the circular motion of the lateral plate and the longitudinal plate for air flow direction adjusting is fixed on the motor axis with screws 7a, 8a. The moving condition of the blow-off air can be selected by varying the fixing positions for the lateral plate and the longitudinal plate arround of the motor shaft of the rotor.

Conventionally, as shown in Fig. 1, one mechanism has been a plurality of vertical wind direction adjusting plates (hereinafter referred to as horizontal plates) arranged at the front panel outlet (1a) provided on the front panel +1 of the air conditioner. ) (2), and a plurality of horizontal wind direction adjusting plates (hereinafter referred to as vertical plates) (4) provided in the main body (3) and disposed at the main body outlet (8a). As shown in FIG. 2, the horizontal plate (2) of the front panel ll) is provided with aperture shaft projections (2a) at both ends in the longitudinal direction,
This is inserted into the left and right engagement holes (1b) provided in the front panel air outlet (1a) to make the horizontal plate (2) rotatable, while the boss provided at the end of the horizontal plate (2) (2b) is inserted into the engagement hole (2d) provided in the connecting rod (2C) and the horizontal plate (2) is rotated in a series, thereby controlling the temperature of the conditioned air. The blowing direction in the m direction is controlled at a predetermined angle.

As shown in Fig. 8, the vertical plate (4) of the main body (3) has the same structure as the horizontal plate (2), and the vertical plate (4) has a 9:6+ The rotation shaft protrusion (4a) provided on the magazine
) and the bosses (4b) provided at the ends of the vertical plate (4) are connected to the engagement holes (8) provided in the main body outlet II (3a), respectively.
b) is inserted into and engaged with the engagement hole (4d) provided in the connecting rod (4c). As shown in Figure 1, the connecting rod (4C) has a protruding portion (4e) in a direction perpendicular to its longitudinal direction, and a long hole (4f) is provided in this portion. On the other hand, a rotor (5a) extending in the radial direction is fixed to the rotating shaft of a 1d movable shaft 5) that rotates the vertical plate (4) periodically, and the rotor (5a) has an Ail mark on its tip. Due to the 71° structure that includes a shaft-like protrusion (513) that can be inserted into the elongated hole (4f) of the connecting rod (4C) and can move freely, when the electric motor +11411 rotates, the shaft-like protrusion (5b) of the rotor (5a) On the other hand, the connecting rod (4C) reciprocates laterally due to the action of the elongated hole (4f) in which the shaft-like projection (5b) of the child (5a) is inserted.
