BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning air outlet which is attached to an air chamber at the end of a duct of an air-conditioning / ventilating facility, and more particularly to two air outlets whose positions can be independently changed to one air outlet. It is provided with a nozzle for use.

2. Description of the Related Art Conventionally, in facilities such as air conditioning and ventilation, air whose temperature and humidity have been controlled has been guided by ducts provided in the facility and blown to necessary places. An appropriate air volume is calculated in advance by a duct design method or the like, and an air conditioning air outlet to be attached to the front of the air chamber at the end of the duct is appropriately selected from an appropriate type. The air whose temperature and humidity have been adjusted has been directed from the air outlet so as to be able to circulate in the space appropriately.
The direction of the wind has to be adjusted individually for each guide blade depending on the air outlet for air conditioning, and the air volume is adjusted by an air adjusting valve or the like. Furthermore, the air-conditioning air outlet is designed so that the blown air can reach the space evenly, and when installing a plurality of air-conditioning air outlets, it is necessary to adjust the installation position throughout the space. Was.

[0003]

Since the conventional air outlet for air conditioning has only one outlet, it is necessary to blow air in two different directions simultaneously or to blow air in only one direction. In this case, two air outlets must be provided, and each air outlet must be opened and closed by an air control valve for adjustment. Also, since the conventional air-conditioning air outlet is designed so that the blown air can reach the space evenly, when a plurality of air-conditioning air outlets are installed,
Position adjustment of a plurality of air-conditioning air outlets must be performed so that air is evenly distributed in the entire space, which is very troublesome. Furthermore, in order to change the direction of the wind, adjust the guide vanes of the air-conditioning air outlet installed at a relatively high place one by one, or, if there is no guide vane, manufacture and attach a dedicated nozzle individually It had to be very time consuming. Therefore, an object of the present invention is to provide an air-conditioning air outlet having two outlets that can freely adjust the blowing direction and air volume.

[0004]

In order to achieve the above-mentioned object, a sphere is provided on a rotation holding portion at the front opening of the air chamber at an air-conditioning air outlet attached to the front of the air chamber at the end of a duct of an air-conditioning / ventilation facility. The outer shell is rotatably held, the outer shell is provided with an air inlet on the rear side, and a first nozzle and a long hole for air blowing are provided on the front side. A guide is provided on both peripheral edges in the direction, an inner shell having a second nozzle for air blowing is slidably held by the guide, and a fixed partition plate that partitions between the two nozzles inside an outer shell; A movable partition plate for controlling the amount of air supplied to the two nozzles was provided.

[0005]

In the air-conditioning air outlet according to the present invention, since the outer shell having the first nozzle for air blowing is rotatably held by the rotation holding portion of the air chamber, the outer shell is rotated. Thereby, the mouth of the first nozzle for air blowing can be directed in a desired direction. In addition, the inner shell having the second air blowing nozzle protruding from the long hole of the outer shell is guided along the guide without being detached from the inner surface of the outer shell by the guides provided in both longitudinal directions of the periphery of the long hole. It can slide on the inner surface of the outer shell. Therefore, by sliding the inner shell with respect to the outer shell, the second nozzle for air blowing can be directed in a desired direction independently of the first nozzle for air blowing on the outer shell. Also,
Since the fixed partition plate and the movable partition plate are provided inside the outer shell, the air sent from the air chamber at the tip of the duct can be supplied to one or both of the first and second nozzles as necessary. Can be diverted freely. Further, by adjusting the position of the movable partition plate, it is possible to adjust the flow rate of the diverted air, thereby increasing the amount of air flowing out of both nozzles on one side and decreasing the amount on the other side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. A circular opening is provided at the front of the air chamber 1 at the end of the duct A. A spherical belt-shaped rotation holding unit 1a is attached to the periphery of the opening. On the other hand, the air-conditioning air outlet B is formed in a spherical shape from a spherical outer shell 2 having a circular notch and an inner shell 3 slidably inscribed on the inner surface of the outer shell. The surface of the spherical outer shell 2 of the air-conditioning air outlet B is
The equatorial plane is surrounded by a spherical band, and is held by the rotation holding unit 1a so as to be rotatable and slidable. On the side of the outer shell 2 that is inside the air chamber 1, a large circular notch is provided as an air inlet 2a.
Furthermore, on the side of the outer shell 2 that is outside the air chamber,
A circular opening 2b and a substantially rectangular long hole 2c are provided. A cylindrical air blowing first nozzle 4 having a diameter corresponding to the diameter of the opening 2b is protruded from the circular opening 2b. That is, the air sent from the air chamber 1 can be blown in the direction of the first nozzle 4 for blowing air. Further, the outer shell 2 of the air-conditioning air outlet B is held by the rotation holding part 1a and slidably rotated, whereby the direction of the first air-blowing nozzle 4 can be freely changed. This is indicated by the arrow in FIG.

The elongated hole 2c provided in the outer shell 2 is set to be a slightly longer, substantially rectangular shape whose longitudinal direction is directed toward the circular opening 2b. The width of the long hole 2c is set to be the same as the diameter of a cylindrical second nozzle 5 for air blowing, which will be described later, and has a semicircular shape at both ends in the longitudinal direction corresponding to the cylindrical diameter of the second nozzle 5. It is rounded. Further, a guide 2d for attaching the inner shell 3 is provided on the inner side surface of the outer shell 2 provided with the elongated hole 2c along the upper and lower edges in the longitudinal direction of the elongated hole 2c. The guide 2d includes an L-shaped member slightly longer than the long side of the long hole 2c, and a concave member having a width equal to the thickness of the inner shell 3 between the upper and lower edges of the long hole 2c and the inner surface of the outer shell 2. It is attached so that a groove can be made. On the other hand, inner shell 3 is outer shell 2

According to the present invention, the air-conditioning air outlet according to the present invention is provided with two air-conditioning air outlets provided with two blow-off nozzles capable of freely setting the direction and amount of air. Therefore, it is possible to increase the air conditioning efficiency by changing the wind direction and the air volume flexibly according to the situation, and to reduce the power consumption required for the air conditioning. Also, in terms of the construction of the equipment, two air outlets were conventionally required when two air were separately blown simultaneously from one air chamber in the past, but only one air outlet was required. Significant improvement was seen in the construction price. Furthermore, in terms of the living environment, unlike conventional air conditioning systems that only use temperature and humidity adjustments using air conditioning air outlets, the direction and amount of air can be freely adjusted to blow out a comfortable airflow suitable for environmental situations. It is possible to construct a new air conditioning system that can create an unprecedented new feeling of comfort.
