Description

[Detailed description of the invention]

[Industrial Application Field 1] The present invention relates to an air conditioning system that is equipped with a blower device that blows air into a room, and an exhaust device that exhausts air from the room, and in which an air outlet and an exhaust port open on a ceiling surface. ．． [Prior Art] Conventionally, as shown in FIG. 3, this type of air conditioning system has been provided in which an air outlet 1 of a blower device and an exhaust port 2 of an exhaust device open toward the ceiling surface. There is. In this air conditioning system, air is sent downward from an air outlet 1, circulates within the room, and is discharged to the outside from an exhaust port 2.

[Problem to be solved by the invention]

In the above conventional configuration, even if air contaminated with cigarette smoke etc. accumulates in the upper part of the room, the suction range of the exhaust port 2 (
If the air does not enter the area (encircled by the broken line in Figure 3), it cannot be fully exhausted, resulting in the problem that dirty air remains in the room for a long time. The present invention aims to solve the above-mentioned problems, and by making the blowing direction of air from the air outlet variable, the air near the ceiling can be moved as necessary, and the air near the ceiling can be moved. The aim is to provide an air conditioning system that can exhaust air outside the room in a short period of time.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a pollution sensor that detects indoor air pollution and outputs a control signal, a remote control receiver that outputs a control signal in response to a remote control signal from a remote control transmitter, etc. A control signal output device is provided, and a vane that changes the direction of air blowing is arranged at the air outlet, and when a control signal is output from the control signal output device, the blowing direction of the air blower is directed along the ceiling surface to the exhaust device. The control device adjusts the direction of the vane so that it is set in the direction toward which it is facing.

[Effect]

According to the above configuration, when the control signal is output from the control signal output device, the direction of the vane provided at the air outlet is adjusted so that the direction of air blowing is directed toward the exhaust device along the ceiling surface. Therefore, when a control signal is output, the air stagnant near the ceiling is forced to flow toward the exhaust port by the air sent out from the air outlet, efficiently discharging dirty air outside. It can be done.

【Example】

As shown in FIG. 1, the blowing box 3 conveyed to the blowing device,
Exhaust boxes 4 communicating with an exhaust device are arranged on the ceiling, and an air outlet 1 provided in the air outlet box 3 and an exhaust port 2 provided in the exhaust box 4 open on the ceiling surface. A vane 5 is arranged inside the air outlet box 3 facing the air outlet 1. The vane 5 is a plate body that is rotatable around an axis parallel to the opening surface of the air outlet 1 and whose inclination angle with respect to the opening surface of the air outlet 1 is variable.
By changing the angle of inclination of the vane 5 with respect to the opening surface of the air outlet 1, the air blowing direction can be changed. The exhaust port 2 is arranged on the downstream side of the air flow when the air blowing direction is along the ceiling surface. Further, a smoke sensor 6, which is a type of pollution sensor, is arranged between the air outlet 1 and the exhaust outlet 2 to detect dirt in the indoor air.
Further, a remote control receiver 8 is provided to receive a remote control signal by infrared rays transmitted from the remote control transmitter 7.
Smoke sensor 6 and remote control receiver 8 which are control signal output devices
is connected to the control circuit 9, as shown in FIG. A control signal is sent to circuit 9. When the control circuit 9 receives the control signal, it drives the vane driving device 11, which is a control device, to adjust the angle of the vane 5 so that the direction of air blowing from the air outlet 1 is along the ceiling surface. Also, smoke sensor 6 and remote control receiver 8!
When no control signal is output from the vane 8, the control circuit 9 controls the vane driving device l1 so that the vane 5 performs an intermittent reciprocating operation. Here, the intermittent reciprocating motion is an operation in which the vane 5 is temporarily stopped at both ends of the reciprocating motion range of the vane 5. By this operation, the amount of air sent to the area remote from the air outlet 1 is made larger than that directly below the air outlet 1, and the air is sent almost evenly over the entire area of the room. Since the smoke from the cigarette 10 is lighter than air, it rises to the vicinity of the ceiling, and when the smoke concentration increases, the presence of smoke is detected by the smoke sensor 6, so the air flow sent out from the outlet 1 reaches the exhaust outlet 2. The angle of the bench 5 is fixed for a certain period of time so that the In this way, smoke is introduced into the exhaust port 2 and exhausted outside the room in a short time. Also, if a person in the room uses wireless transmission 81
7, the angle of the vane 5 is fixed for a certain period of time so that the airflow from the air outlet 1 is directed toward the exhaust port 2, and smoke is quickly discharged.6 On the other hand, smoke detected by the smoke sensor 6 When the concentration is low, the vane 5 performs the above-mentioned intermittent reciprocating operation and sequentially changes the angle of the air outlet l with respect to the opening surface, so that air is blown evenly to each location in the room and the air in the room is agitated. By doing so, the room temperature becomes uniform. In the above embodiment, the vane 5 can be controlled by both the smoke sensor 6 and the remote control receiver 8, but it may be possible to control only one of them.

【Effect of the invention】

As described above, the present invention provides a control signal output device such as a pollution sensor that detects indoor air pollution and outputs a control signal, and a remote control receiver that outputs a control signal in response to a remote control signal from a remote control transmitter. A vane that changes the blowing direction of air is arranged at the blower outlet, and when a control signal is output from the control signal output device, the blowing direction of the blower is set to face the exhaust device along the ceiling surface. Since the control device adjusts the direction of the vane so that the vane is oriented, when a control signal is output, the air stagnant near the ceiling is directed toward the exhaust port by the air sent out from the outlet. This has the advantage that dirty air can be efficiently discharged outside the room.
