Description

[Detailed description of the invention] [Industrial application field]

The present invention includes a blower device that blows air into a room;
The present invention relates to an air conditioning system that includes an exhaust device that exhausts air from a room, and has an air outlet and an exhaust outlet that open on a ceiling surface.

[Conventional technology]

BACKGROUND 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 a ceiling surface. In this air conditioning system, the air outlet 1
The air sent out further downward circulates within the room and is discharged outside from the exhaust port 2.

Problems to be Solved by the Invention In the above conventional configuration, even if air contaminated by cigarette smoke etc. accumulates in the upper part of the room, the suction range of the exhaust port 2 (encircled by the broken line in FIG. If the air does not enter the room, it cannot be fully exhausted, and the problem is that the 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 purpose of the present invention 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, and a remote control receiver that outputs a control signal in response to a remote control signal from a remote control transmitter. A control signal output device is provided, a vane that changes the blowing direction of air is arranged at the air outlet, and when a control signal is output from the control signal output device, the blowing direction of the blower device is directed toward the exhaust device along the ceiling surface. The control device adjusts the direction of the vane so that the direction is set.

[Effect]

According to the above configuration, when a 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 air blowing direction 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, an air outlet box 3 communicating with an air blower and an exhaust box 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 box 4 provided in the air outlet box 3 are arranged on the ceiling.
An exhaust port 2 provided at the top opens to the ceiling surface. A vane 5 is disposed inside the blow-off box 3 facing the blow-off port 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 inclination angle 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 blower 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 sent from the remote control transmitter 7. The smoke sensor 6 and remote control receiver 8, which are control signal output devices, are connected to a control circuit 9 as shown in FIG.
When smoke from a cigarette 10 is detected by the smoke sensor 6, or when the remote control receiver 8
When a remote control signal is received, a control signal is sent to the control circuit 9. When the control circuit 9 receives the control signal, it drives the vane drive device 11, which is a control device, to adjust the angle of the vane 5 so that the direction of air blowing out from the air outlet 1 is along the ceiling surface. Further, when no control signal is output from the smoke sensor 6 or the remote control receiver 8, the control circuit 9 controls the vane drive device 11 so that the vane 5 performs an intermittent reciprocating operation. Here, the intermittent reciprocating operation is an operation in which the vane 5 is temporarily stopped at both ends of the reciprocating movement 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 the area directly below the air outlet 1, so that 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 vane 5 is fixed for a certain period of time so that the vane 5 is directed toward the target. thus,
Smoke is introduced into the exhaust port 2 and exhausted outside the room in a short time. Also, when a person in the room operates the wireless transmitter 7, the air outlet 1
vane 5 so that the airflow from
fix the angle for a certain period of time to expel smoke quickly.
On the other hand, when the smoke concentration detected by the smoke sensor 6 is low, the vane 5 performs the above-mentioned intermittent reciprocating operation and successively changes the angle with respect to the opening surface of the air outlet 1, so that it is distributed evenly to each location in the room. By blowing air and stirring the air in the room, the room temperature becomes uniform. In the above embodiment, the vane 5 is controlled by the smoke sensor 6.
Although it is possible to perform this with both the remote control receiver 8 and the remote control receiver 8, it is also possible to use 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 toward the exhaust device along the ceiling surface. The control device adjusts the direction of the vanes so that when the control signal is output, the air stagnant near the ceiling is directed toward the exhaust port by the air sent out from the outlet. It has the advantage of being able to efficiently exhaust dirty air outside the room.
