DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a plurality of air outlets.

[0002]

2. Description of the Related Art In home and commercial air conditioners, an indoor unit provided at one place in a room takes in air before air conditioning in the room and brings the air into contact with a heat exchanger to control temperature and humidity. , That is, air conditioning is performed, and the air after the air conditioning is discharged into the room. Such an air conditioner usually has an inlet for taking in air before air conditioning into an indoor unit and an outlet for discharging air after air conditioning to the room.

For example, a conventional air conditioner 50 shown in FIG.
And the intake air 51 is the intake 5
7, the temperature is adjusted by a heat exchanger 52, the air is sent out by a fan 53, and the air 56 is blown out from an air outlet 55 mainly arranged in front of the indoor unit via a louver (drifting plate) 54. It is configured to be discharged into the room.

[0004]

However, in such a conventional configuration, since there is only one outlet at the front, the convection of the indoor air is not effectively performed. It is difficult to efficiently reduce the temperature difference and reduce the temperature unevenness in the room.

In addition, since the cold air is blown into the room from the front outlet during the dry operation, the cold air is blown directly to the human body, which lowers the sensible temperature and may cause discomfort. .

Further, since there is only one outlet at the front, the flow path resistance of the wind is large, so that the wind noise becomes loud and it is difficult to operate silently.

SUMMARY OF THE INVENTION The present invention has been made to solve such problems and disadvantages. The purpose of the present invention is to reduce the temperature unevenness in a room at the time of cooling and heating, and to enable operation without directly blowing cold air to a human body at the time of dehumidification. Therefore, it is an object of the present invention to provide an air conditioner device capable of quiet operation with reduced wind noise.

[0008]

In order to achieve the above object, an air conditioner according to the present invention is provided with an intake for taking in room air at the front, and a heat exchanger provided adjacent to the intake. In an air conditioner provided with one cross flow fan obliquely below the heat exchanger, a front outlet for discharging air is provided in front of the cross flow fan and below the intake port, and a cross flow fan is provided. And an upper duct for discharging air upward from the air conditioner equipment and an outlet connected thereto are provided, and an air flow control valve is provided at each of the front outlet and the inlet of the upper duct.

[0009]

In the air conditioner according to the present invention, since the air amount control means controls the amount of conditioned air blown out from the plurality of outlets in different directions in the room, the air flow discharged into the room can be controlled in a plurality of systems. And promote convection of indoor air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. First, the configuration of the present invention will be described. FIG. 1 is a partial sectional perspective view of an embodiment of an air conditioner according to the present invention.

An air conditioner 1 according to the present invention has an intake 10 for taking in room air at the front, and an intake 1
The heat exchanger 9 is provided adjacent to the heat exchanger 0, and the cross flow fan 7 is disposed diagonally below the heat exchanger 9. An upper duct 6 is provided diagonally behind the heat exchanger 9, and an upper outlet 3 is provided at an upper end of the upper duct 6 for discharging air sent from the cross flow fan 7 upward from the air conditioner 1. Upper duct 6
An upper air volume control valve 5 (air volume control means) is provided near the entrance.

A front outlet 2 is provided below the front of the air conditioner 1 adjacent to the cross flow fan 7, and a front air flow control valve 4 (air flow control means) is disposed between the cross flow fan 7 and the front air outlet 2. Set up. Further, a controller 8 for controlling the upper air volume control valve 5 and the front air volume control valve 4 is provided in the air conditioner device 1.

As described above, the air conditioner according to the present invention is provided with two air outlets for blowing air in different directions in the room, that is, upward and front, respectively, and provided with air flow control valves in each of them, and the controller controls the air flow. It controls the control valve.

Next, the operation will be described. When the cross flow fan 7 rotates, the room air is taken in from the intake port 10, and the air is heated or cooled by the heat exchanger 9 to control the temperature. Is discharged upward from the upper outlet 3. Alternatively, it is discharged from the front outlet 2 forward.

The controller 8 controls the opening of the upper airflow control valve 5 near the entrance of the upper duct 6 and the opening of the front airflow control valve 4 adjacent to the front outlet 2. FIG. 2 shows an operation flowchart of the controller 8.

In FIG. 2, when the silent operation is given the highest priority (step S1), the controller 8 fully opens both the upper air flow control valve 5 and the front air flow control valve 4 (step S1).
2) The operation is performed with the air resistance minimized.

When the silent operation is not given the highest priority, in the cooling (step S3), for example, the following control is performed.
The front air flow control valve 4 is controlled so that the flow rate from the front outlet 2 is 30% (Step S4), and the front air flow control valve 4 is controlled so that the flow rate from the upper outlet 3 is 70% (Step S5). I do. With this control,
Two systems of airflow are generated in the room, and convection in the room is promoted, so that the cooled air can be prevented from staying in the ceiling portion, and thus the cooling effect can be improved.

In the dehumidification (step S3)
For example, control is performed as follows. The front air flow control valve 4 is fully closed so that the flow rate from the front outlet 2 becomes zero (step S
6) Then, the front air flow control valve 4 is fully opened so that the flow rate from the upper outlet 3 is set to 100% (step S7). With this control, it is possible to prevent the flow of the cool air during the dry operation from blowing on the human body.

Further, in heating (step S3)
For example, control is performed as follows. The front air flow control valve 4 is controlled so that the flow rate from the front outlet 2 is 70% (Step S8), and the front air flow control valve 4 is controlled so that the flow rate from the upper outlet 3 is 30% (Step S9). I do. By this control, two systems of airflow are generated in the room, convection in the room is promoted, and the warmed air can be prevented from staying in the ceiling portion, so that the heating effect can be improved.

[0020]

As described above, the air conditioner according to the present invention is provided with a plurality of air outlets for blowing air from the intakes in different directions in the room, and at least one of the air outlets is provided with at least one air outlet. Since air amount control means is provided,
By having multiple systems of airflow released into the room, control can be performed more easily than before, and air convection becomes effective,
Reduce the indoor temperature difference during cooling and heating,
Indoor temperature unevenness can be reduced.

In particular, during the dry (dehumidification) operation, by discharging the cool air upward rather than forward, dehumidification can be performed by an operation without directly blowing cool air to the human body. In addition, when silent operation is required, the plurality of air outlets are fully opened to reduce the flow resistance of the wind, thereby suppressing wind noise and enabling silent operation.
