Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a structure of an air-conditioning air blowing unit device in an air-conditioning facility such as a room cooler.

[Problems to be solved by conventional techniques and devices]

In modern buildings, air conditioning (air conditioning) is performed so that the temperature and humidity inside each room are kept substantially constant throughout the year.
It is common practice to have a system.

In addition, air conditioners, room coolers, and the like are often provided as cooling and heating facilities in general dwellings. Further, in passenger cars and the like, air conditioners for vehicles are often used as standard devices.

A louver (blowout airflow direction adjusting device) that controls the airflow direction of the airflow in the vertical direction and the leftward and rightward direction and a shield plate that adjusts the amount of airflow are installed in the unit that blows out the conditioned air in such an air conditioning facility.

In this case, a control body that adjusts the vertical direction of the conditioned air and a shield that adjusts the air volume are rotatably supported, and the shield plate and the control body can be independently adjusted and rotated. However, if the rotation resistance at each rotation support shaft portion is low, the orientation of the shielding plate and the control body root plate is arbitrarily changed due to the wind pressure of the blowing air and the vibration of the air conditioning equipment. There was a problem.

The present invention aims to solve this technical problem.

[Means for Solving the Problems]

In order to achieve this object, the present invention is to adjust the ventilation area of the ventilation hole in a box having a ventilation opening for conditioned air on the front surface and a ventilation hole for introducing the conditioned air inside thereof. In the air-conditioning air blowing unit device in which the shielding plate and the control body for controlling the blowing air direction in the vertical direction are rotatably provided, the control body of the control body is arranged along the left-right longitudinal direction of the box body. The shielding plates are arranged in parallel outside, and the control body is arranged so that the left and right ends thereof are located inside the side plate portions at the left and right ends of the shielding plate, respectively, while the control bodies are directed inwardly on the left and right side plates of the box body. The left and right side plate portions of the shield plate and the left and right ends of the control body are rotatably supported by a pair of left and right supporting shafts to be attached,
On the outer periphery of the support shaft, free rotation restraining means are respectively inserted between the left and right side plate portions of the shielding plate and the left and right ends of the control body.

[Operation and effect of device]

In this way, the shielding plate is disposed outside the control body disposed inside the box body, and the control body and the shielding plate are disposed so that their longitudinal directions are parallel to each other. Since the left and right ends of the control body are arranged between the parts, the control body is located inside the left and right side plate parts of the shield plate, and the left and right ends of the control body approach the left and right side plate parts of the shield plate. It can be arranged in a closed state.

Moreover, since a pair of left and right support shafts mounted inwardly on both left and right side plates of the box body pivotally support the left and right ends of the control body and the left and right side plates of the shield plate, the pair of left and right support shafts may be short. .

Further, since the shield plate and the control body are rotated concentrically with respect to the pair of left and right support shafts, when the shield plate is rotated around the support shafts, the ventilation area for the ventilation hole in the box body is adjusted to be increased or decreased. On the other hand, the blowing direction of the conditioned air can be changed up and down by rotating the control body around the support shaft, and the structure for supporting these can be simplified.

The free rotation inhibiting means between the left and right side plate portions of the shield plate and the outer periphery of the support shaft can hold the posture after the shield plate is rotated, and similarly, the left and right ends of the control body and the support shaft outer periphery can be similarly held. Since the free rotation inhibiting means provided between the control unit and the control unit can hold the posture of the control unit after changing the vertical rotation, the rotation position of the shield plate and the control unit can be controlled by the pressure of the conditioned air passing through the blowing unit. This has the effect that the vertical tilt angle does not fluctuate or fluctuate carelessly.
