DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a duct type air conditioner (hereinafter referred to as a duct type air conditioner).

BACKGROUND OF THE INVENTION Recently, as an air conditioning method, a method has begun to be adopted in which air conditioning is performed by arranging ducts in each room without providing an indoor unit, instead of providing an indoor unit for each room. As shown in Fig. 2, such a duct type air conditioner has an air conditioner main body 24 installed in the ceiling 21 that includes a heat exchanger 22 and a blower 23 that ventilates the heat exchanger 22. A suction chamber 26 with a suction grill 25 attached to the ceiling surface 28, which is one of the two, and an outlet chamber 29 with an outlet grill 27 in the same room are connected to the air conditioner main body 24 by ducts 30, respectively. There is. Therefore, if the air conditioner is installed in multiple rooms, a suction chamber (not shown) with a suction grill attached to the ceiling of each room and a blowout chamber 29a with a blowout grill 27a attached are installed on the ceiling of each room. Attachment port 3 for connecting the duct 30 to the blowout side chamber 31
2a and 32b are provided to divide the blown air. Furthermore, in case the air conditioning loads of a plurality of rooms are different, the blowing chamber 29 and the blowing chamber 29a
A damper 3 is installed at each duct connection port 33a, 33b.
4a, 34b, and manually or automatically damper 34a.

By adjusting the opening degree of 34b, the air volume was adjusted to enable operation commensurate with each air conditioning load.

Problems that the invention aims to solve In such conventional configurations, the damper 34a.

34b to reduce the air volume (and the speed of the air blown from the air outlet grill 27 or the air outlet grill 27a decreases, the amount of air reaching the floor surface decreases, and a comfortable temperature distribution is achieved. The problem was that it became impossible to obtain

The present invention solves these problems, and provides a blow-off device that can secure the blow-out air speed from the blow-off grill and provide a comfortable temperature distribution even when the opening degree of the damper is adjusted to reduce the air volume. This is what I am trying to do.

Means for Solving the Problems In order to solve this problem, the present invention includes a damper at the duct attachment port on one side of the air outlet body, a grill connected to the air outlet body, and an air blower connected to the grille that communicates with the air duct. a circulation air outlet, a circulation air outlet, and a circulation suction port; an upper partition plate is provided between the blowing air path and the air blowing air path communicating with the circulation air outlet; An indoor circulation blower is provided between a suction air path corresponding to the mouth and a blowout air path corresponding to the circulation air outlet, and an upper partition plate is provided below the indoor circulation blower. It is something.

Effect: With this configuration, when the air volume from the air conditioner body is reduced to adjust the opening degree of the damper, and the speed of the air blowing from the air outlet decreases, the indoor circulation blower operates to cause the air flow to flow into the blowing air path. When the air velocity of the connected circulation outlet is added and reaches the floor surface, and the damper is fully opened, the indoor circulation blower stops and the air is blown out at the speed only from the air duct, closing the damper. Then,
Indoor air is circulated only by the indoor circulation blower, and a good temperature distribution in the room is always ensured in any case.

EXAMPLE An example of the present invention will be described below with reference to FIG. In the figure, the blowout main body 16 has a blowout chamber 1.
A duct attachment port 3 is provided on one side 2 of the air conditioner, and a duct 4 connected to the main body of the air conditioner (not shown) is attached thereto. In addition, the duct installation port 3 is provided with a damper 5 for adjusting air volume.
is provided, and the amount of air from the air conditioner body is adjusted by the opening degree of this damper 5. An indoor circulation blower 6 is provided inside the blowout chamber 1, and the indoor circulation blower 6 is divided into a suction air path 7 and a blowout air path 8. An upper partition plate 10 is provided between the air passage 9 and the air passage 9 through which air is blown. Further, the lower surface of the blowout main body 16 is attached to the ceiling surface by joining the blowout grille 12. The blowout grill 12
The air outlet 15 communicates with the air passage 9 and is equipped with a looper 15a, and the circulation outlet 14 is also provided with a looper 14a on the side of the air passage 8 defined by the upper partition plate 10. It is set up.

Further, a circulation suction port 13 is provided corresponding to the suction air passage 7, and an upper partition plate 1 for forming the suction air passage 7 and the blowing air passage 8.
1 is provided.

In the above configuration, the volume of air sent from the air conditioner main body through the duct 4 is adjusted by the damper 5, and is mainly blown into the room through the air blowing outlet 15 through the blowing air passage 9. At this time, when the amount of air is throttled by the damper 5, the amount of air passing through the air passage 9 is small, and therefore the amount of air blown out from the air outlet 15 is also small, so there is no blown air velocity and it does not reach the living space. do not. Therefore, at this time, by operating the indoor circulation blower 6, indoor air is sucked in from the circulation suction port 13, flows through the suction air path 7, flows into the blowout air path 8, and then flows from the circulation air outlet 14. By blowing out the air, the air blows out from the air blowing outlet 15 and the wind speed becomes high, and the air can reach the living space or the floor. As a result, a sufficiently good temperature distribution can be achieved even if the air volume is reduced by the damper 5. Next, when the damper 5 is closed, only the indoor circulation blower 6 is operated to gently and evenly distribute the indoor air. Next, when the damper 5 is fully opened, the indoor circulation fan 6 is stopped and the air volume and speed blown out from the air outlet 15 is sufficient, so the indoor temperature distribution is maintained sufficiently well. be.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a damper at the duct attachment port of the blowout main body, and an upper cutting plate provided inside the blowout main body between the blowing air path and the blowout air path. , an air blowing outlet, a circulation air outlet, and a circulation suction port are provided on the air outlet grille joined to the air outlet body, and an indoor circulation air blower is provided in the suction air path via a lower cutting plate. Therefore, when the damper is used to reduce the air volume, the indoor circulation blower can be used to increase the speed of the air, which helps maintain a good and even temperature distribution in the room, and when the damper is closed, The indoor circulation blower is operated to circulate indoor air to maintain a uniform temperature distribution, and when the damper is fully open, the indoor circulation blower is stopped and the temperature distribution is sufficient with only the air velocity from the air outlet. In either case, sufficient air volume is ensured to reach the floor and living space, and a comfortable temperature distribution is obtained.
