JPS6383541A - Duct device for air conditioner - Google Patents

Abstract

PURPOSE:To facilitate the change of positioning, increase or decrease of the number or addition of openings for air inlets and outlets of respective ducts after the installation has been made by providing the respective side walls of the air outlet duct and inlet duct with multiple air outlet holes and inlet holes which allow the selection of position of the air outlet and inlet openings. CONSTITUTION:An air outlet duct 2 one end of which is connected to the air outlet of an air conditioner unit 1 and the other closed end 2a which is extended to the room side of a room A has multiple air outlet holes 3a in one of its side walls in its lengthwise direction. An air inlet duct 5 one end of which is connected to the air inlet of the unit 1 is extended alongside the outlet duct 2, and its blind end 5a is formed on the midway of the outlet duct 2 so that it may be staggered with the blind end 2a of the outlet duct 2. Its side wall has multiple room air inlet holes 4a in its lengthwise direction. The number and position of common plug caps 7 detachably fitted to the outlet holes 3a can be changed to adjust the air outlet position and air blowing rate as desired.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a duct device for an air conditioner in which the position of an air outlet and an air inlet can be freely changed.

[Conventional technology]

Figure 3 is a perspective view of the duct device of a conventional air conditioner shown in Japanese Patent Application Laid-Open No. 81-49050. (3) is the wind outlet at the tip of the air duct), (4) is the air conditioner main body (1)
The wind suction port (6) of the suction duct (5) drawn out from the air intake duct (6) is located on the partition wall of the room (A) that connects each of the above-mentioned ducts.

In the above configuration, for example, indoors (in the case of AJ air conditioning).

The air cooled by the air conditioner main body (1) passes through the air duct +2) and is blown out into the room (A) through the air outlet (3) at the tip of the air duct, which is then blown out into the room (A) divided by the partition wall (6). After cooling the inside of the air conditioner (body), air is sucked in through the suction port (4) at the tip of the suction duct (5), and returns to the air conditioner body (1) through the suction duct (5).

[Problem that the invention seeks to solve]

Since the conventional duct device is configured as above,
Since the air outlets and suction ports of each duct located indoors are located at fixed locations, there is a problem in that the air conditioning environment cannot be changed in response to, for example, rearranging the interior of the room.

This invention was developed to solve the above problems, and it is designed to easily change the open position of the outlet and suction ports of each duct, increase or decrease them, or add them after installation. purpose.

[Means for solving problems]

In the case of this invention, the lengths drawn out from the air conditioner main body are different. In addition to closing the ends of each of the wind blowing duct and suction duct, a multi-sided blowing hole and a suction hole are opened on each side wall surface, and by selectively blocking each blowing hole and suction hole, wrinkled wind blows out. Mouth position.

It is designed to change the position of the suction port and increase or decrease its position.

[Effect]

In the case of this invention, the most efficient air conditioning environment can be obtained very easily depending on the indoor situation by selectively opening and closing the air outlet size of the air outlet duct and suction duct arranged indoors and the suction hole.

〔Example〕

An embodiment of this invention will be described below. That is, in Figures 1 and 2, +1) is the air conditioner main body, (
2) has one end communicating with the air outlet of the main body of the air conditioner, and the other end of the closed part (2) is an outlet duct drawn out indoors along the ceiling surface of the room (4), for example, and its - A large number of holes (3a) through which air flows into the room (A) are arranged in the side wall surface in the extending direction.One end of (5) communicates with the air intake port of the air conditioner main body (1). and with the suction duct drawn out along the said blow-off duct (2) into a state of overlap with this.

The closing part (5a) at the tip thereof is formed in the middle of the outlet duct (2) so as to wrap around the tip closing part (2) of the outlet duct (2) in the protruding direction. , and its side wall has indoor air intake holes (4
A large number of ri are arranged in the direction of its extension. (6; is a partition wall of the room (A) in which each of the above-mentioned air outlet and suction ducts) +21 +5) are provided.

Figure 2 is a partially enlarged sectional view of the above-mentioned outlet duct 12), and (7) in Figure 9 is a common blocking camp removably attached to each outlet hole (3). The position of the air outlet and the amount of air blown can be changed as desired depending on the location of use and the number of devices used.

Note that the same blocking cap is used for the above-mentioned suction duct (
Each of the suction holes (5) (4) are selectively used in the same manner, and the indoor air suction position and suction air volume can be changed in the same manner as described above.

In the above embodiment, a blocking cap is selectively fitted to each of the air outlet and suction holes that are opened when the air outlet and suction ducts are manufactured to correspond to the air-conditioning environment in the room to be air-conditioned. If it becomes necessary to add air outlets and suction holes due to circumstances after each air outlet and suction duct has been installed, the required holes may be opened on site.

〔Effect of the invention〕

Since the duct device of the present invention is configured as described above, the positions of the outlet and inlet and the air volume can be freely adjusted depending on the situation in the room to be air-conditioned, and the optimum air-conditioning environment can be easily created. (In addition, it is possible to add large blowout and suction holes after installing the duct.Also, each blowout hole and suction hole are distributed in the extension direction of each duct, so the blowout can be easily adjusted.) It also has the effect of reducing wind noise.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of essential parts showing an embodiment of the duct device for an air conditioner according to the present invention, FIG. 2 is a partially enlarged sectional view thereof, and FIG. 3 is a perspective view of a conventional duct device for an air conditioner. It is. In the figure, (1) is the air conditioner main body, (2) is the outlet duct, (2 is the blockage part, (3 is the outlet hole, (4 is the suction hole, (5) is the suction duct, (5 is (7) shows the closed camp, and (A) shows the interior of the room.

Claims (2)

[Claims] (1) A blowout duct and a suction duct of different lengths are connected at one end to the air conditioner main body and extend into the room so that the other end is extended in the direction in which the other end is closed.
