Abstract

PURPOSE:To permit local air conditioning without changing the air conditioning of the whole of a room, by a method wherein an air conditioner is provided with a master blow-off port and slave blow-off ports, which receive conditioning air from the main body of an air-conditioning machine through a duct, while the slave blow-off ports are provided with blow-off means with directivity. CONSTITUTION:Air, conditioned by the operation of the main body 8 of an air-conditioning machine, is sent to the first and second ventilating passageways 17, 18 of a blow-off unit 10 through the passageway 1a of a duct 11 while indoor air flows into the passageway 11b through the suction port 20 of a master blow-off port 10a and, thus, ventilation is effected. The air-conditioning air, sent into the ventilating passageway 17, flows to the outer peripheral direction of the master blow-off port 10a to effect normal cooling or heating of the whole of a room. On the other hand, the air-conditioning air, which flowed into the ventilating passageway 18, is regulated in the blow-off strength thereof in a blow-off tube 14 in the slave blow-off port 10b in accordance with the position of an air volume body 15 whereby blow-off stream with a directivity may be obtained. The position of local cooling or local heating may be changed by regulating the position of the swingable blow-off tube 14.

Description

[Detailed description of the invention] Industrial applications The present invention relates to an air conditioner capable of local cooling.

2. Description of the Related Art In general, in indoor air conditioning, as shown in FIG. The system blows out more conditioned air to condition the air in each room 2 and 3. Note that the arrows in the figure indicate the flow of air.

Problems to be Solved by the Invention The above-mentioned air outlet body 4 blows out a wide air in order to cool and heat the entire room, and although the blowing direction can be changed with the deflection plate 6, spot cooling or spot heating is not possible. It was impossible.

By the way, in modern house structures, for example, the living room and dining room are increasingly constructed in one double room, and within that room, strong cooling or heating is often required depending on the location. .

Also, for example, when a person enters a room from outside at a temperature different from the temperature inside the room, normal cooling or heating may not be sufficient and rapid cooling or heating may be required. It may not be desirable to change the air conditioning status of the entire room, and there are inconveniences in its use.

The present invention has been made in consideration of the above-mentioned conventional problems, and aims to provide an air conditioner that enables local air conditioning without changing the air conditioning of the entire room.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems includes an air conditioner main body and a system that is provided in one room and receives conditioned air from the air conditioner main body through a duct. The air conditioner has a main outlet body and a child outlet body, and the child outlet body has a directional blowing means.

Function: The air conditioner with the above configuration cools and heats the entire room by blowing out a wide range of conditioned air from the parent outlet body, and cools and cools the entire room by blowing out conditioned air in a directional manner. This results in strong local cooling and heating in the heated room.

Example An embodiment of the present invention will be described below with reference to FIG.

In the figure, 7 indicates a house, and an air conditioner main body 8 is installed outside the house, and an air outlet unit 1o is attached to the ceiling 9 of the room, and the air conditioner main body 8 and the air outlet unit 1o are They are connected by a duct 11 having suction and exhaust passages 11a and 11b.

The outlet unit 1o includes a parent outlet body 10a and a child outlet body 1ob provided at the center thereof. The child outlet body 10b includes a cylinder 13, a blow-off tube 14 which is freely movable within the cylinder 13 and has an arcuate peripheral wall, and a blow-off tube 14 which is freely movable in the axial direction within the blow-off tube 14. It consists of an airporium body 16 having an elliptical cross section. The cylindrical body 13 of the child outlet body 1ob and the parent outlet body 1
A first ventilation passage 17 is formed between the body parts 16 of 0a, and a second ventilation passage 18 is formed inside the cylinder body 13. Further, the cylindrical body 13 has seven flange 19 at its tip, so that the first ventilation passage 17 is extended in the outer circumferential direction, and the air is diffused and blown outward.

An exhaust passage 21 having an intake port 20 is formed outside the main outlet body 10a. This exhaust passage 21 is connected to the passage 11b of the duct 11, and also to the first and second ventilation passages 17.
．． 18 communicates with the passage 11a.

In the above configuration, by operating the air conditioner main body 8, the conditioned air passes through the passage 11a of the duct 11 and the first outlet of the outlet 10. The indoor air is sent out to the second ventilation passage 17.
0 flows into the passage 11b of the duct 11 via the exhaust path 21, and ventilation is performed.

The conditioned air sent to the first ventilation path 17 flows out in the outer circumferential direction of the main outlet body 10a, that is, in a wide direction, and performs normal cooling and heating of the entire room. On the other hand, the conditioned air that has flowed into the second ventilation passage 18 is transferred to the outlet tube 1 in the child outlet body 10b.
4, the blowing strength is adjusted by the position of the air volume body 15 with respect to the arc-shaped blowing tube 14, resulting in a directional internal blowing flow. Therefore, strong local cooling or heating can be achieved in an air-conditioned room. Since the blow-off tube 14 is freely movable, by adjusting the position of the blow-off tube 14, the local cooling or heating position can be changed.

FIG. 2 shows a second embodiment of the present invention, in which a child outlet body 10b is provided separately from a master outlet body 10a. This device also performs the same function as the previous embodiment. In addition, in this embodiment, the secondary outlet body 1
A damper 23 is provided in the duct 22 leading to ob, and the damper 23 is opened and closed by a remote switch or the like to control the airflow from the child outlet tree 1ob.

Effects of the Invention As is clear from the description of the embodiments described above, the air conditioner of the present invention includes a main outlet body and a child outlet body, and the child outlet body has a configuration that is directional, that is, performs spot blowing. Therefore, there are devices that can perform strong localized cooling and heating in a room that has been normally cooled and heated, and can perform various types of cooling and heating, and are of great value.
