Description

TECHNICAL FIELD The present invention relates to an air-conditioning blower for a building.

(Prior Art) FIG. 6 and FIG. 7 show a conventional device of this type, in which a ceiling (d) is provided from an air conditioner (b) installed in an air conditioner room (a) through an air supply duct (c). Air conditioner outlet (e)
Conditioned air (g) is blown from the room to the room (f), and outside air is introduced for indoor occupants as shown by the arrow (h), and dirty air due to smoking in the room is shown by the arrow (i). In order to efficiently perform the air conditioning process, the indoor air is partially returned to the air conditioner (b) as indicated by arrows (j) and (k). (See FIG. 6) Then, in the air conditioning outlet (e), as shown in FIG. 7, the air supply duct (c) is connected to the outlet neck (l) to connect the cone type diffusion plate (m). ) Through which the conditioned air is diffused and blown out into the room. The amount of air supplied is controlled by a damper mounted on the neck (l). In the figure, (n) is an outer cone.

(Problems to be Solved by the Invention) According to the above-mentioned conventional device, if the effective temperature difference (the temperature difference between the blown air and the room air) is increased, the amount of blown air is reduced, and the blower capacity, the size of the duct, the power source, etc. Is reduced,
Initial costs, running costs, and maintenance costs can be saved and the occupied space can be reduced, but the following problems occur.

That is, (i) Cold draft occurs during cooling, which causes discomfort to the occupants and causes dew condensation at the outlet.

(Ii) When heating, a strong draft is generated, the reaching distance of the blown air is reduced, and the temperature difference between the ceiling and the living space becomes large, resulting in a waste of energy. Air circulation operation is required, and the ceiling around the air outlet is further polluted by the indoor air attracting action as shown in (q) of FIG.

The present invention has been proposed for the purpose of providing an air conditioning blower capable of solving the above-mentioned problems of the prior art.

(Means for Solving the Problem) In order to achieve the above-mentioned object, an air conditioner blower according to the present invention is an induction guide having an opening for introducing air around the ceiling in an outer peripheral surface, which is mounted on a ceiling outlet. An adjustment cylinder connected to the tip of an air supply duct disposed in the ceiling is slidably fitted into the cylinder, and an intake port that communicates the interior space with the interior space is provided on the ceiling. Has been done.

(Operation) Since the present invention is configured as described above, when the conditioned air is discharged from the adjusting cylinder connected to the tip of the air supply duct provided in the ceiling, the air in the ceiling around the air is attracted. Then, the air in the ceiling is introduced from the opening provided on the outer peripheral surface of the attraction guide cylinder in which the adjusting cylinder is fitted and is blown out into the room from the ceiling outlet.

At this time, the amount of the attracting air can be adjusted by sliding the adjusting barrel up and down along the attracting guide barrel.

At the same time, the same amount of indoor air as the attracted air is sucked into the ceiling through the intake port provided in the ceiling, and the conditioned air and the air in the ceiling are mixed and blown out into the room.

Therefore, the temperature difference between the air supplied to the air outlet and the room can be increased, the temperature difference between the blown air and the room air can be secured, and the air volume of the air supplied and the air returned can be reduced.

(Examples) The present invention will be described below with reference to illustrated examples.

(1) is an induction guide tube connected to a cone type diffusion plate (4) mounted on a ceiling outlet (3) provided on a ceiling (2), and has an opening for introducing air around the ceiling on the outer peripheral surface. (5) is provided.

In the figure, (6) is a guide rod supporting rod. (See FIGS. 4 and 5) (7) is an air supply duct connected to the air conditioner (9) installed in the air conditioner room (8), and is an adjustment connected to the tip of the air duct (7). A tube (10) is slidably fitted in the attraction guide tube (1). In the figure (10a) is the guide tube (1)
It is the operating knob.

The air outlet connection part of the air supply duct (7) can be slid by using a sound deadening flexible duct. A fixed duct may be used if the duct connecting portion above the air outlet is a slide mechanism.

In the figure, (9a) is a return air port of the air conditioner (9), (11) is a hot / cold water coil, (12) is a blower, and (13) is a corridor.

Further, the ceiling (2) is provided with an intake port (16) for communicating the space (14) in the ceiling and the indoor space (15).

Since the illustrated embodiment is configured as described above,
The conditioned air is blown from the adjusting cylinder (10) at the tip of the air supply duct (7) into the indoor space (15) through the attraction guide cylinder (1) and the cone type diffusion plate (4). At the time when the conditioned air is discharged from the tip of the adjusting tube (10), the air in the surrounding ceiling space (14) is attracted, and the opening (5) provided on the outer peripheral surface of the attraction guide tube (1) is provided. ) Introduced from.

At the same time, the same amount of room air as the above-mentioned attracting air is introduced into the intake port (1
The air is sucked into the space (14) in the ceiling via 6), and thus the mixed air of the conditioned air and the air in the ceiling is blown into the indoor space (14).

At this time, the amount of induced air can be adjusted by adjusting the sliding amount of the adjusting cylinder (10). In the figure, L indicates the sliding range of the adjusting cylinder (10).

According to the illustrated embodiment, the air-conditioning air and the air in the ceiling are mixed and blown out into the room in this manner, whereby the difference in air supply to the ceiling outlet (3) and the temperature inside the room can be increased. It is possible to secure a temperature difference between the blown air and the indoor space (14), reduce the air volume of supply air and return air, and reduce the transportation equipment. That is, the blower capacity, the duct size, the power source, the power source, and the like can be downsized, the airflow distribution can be made uniform, cold draft can be prevented during cooling, and the occurrence of dew condensation can be suppressed.

In addition, the reach of blown air is extended when warm air is blown during heating, and the same effect as when equipped with a circulator is provided in a room with a high ceiling.

Furthermore, the intake port (16) can be freely arranged without ducts, and it is easy to change the partition.

Furthermore, according to the above-described embodiment, when the mixed air of the conditioned air and the air in the ceiling is blown out from the air outlet (3), it is possible to attract indoor air on the ceiling surface that stains the ceiling surface as in the conventional case. In addition, since the room air is sucked in the ceiling intake port (9) perpendicularly to the suction surface, the dirt on the ceiling surface can be prevented in combination with the prevention of dirt on the surrounding area.

(Advantages of the Invention) As described above, according to the air conditioner blower of the present invention, the ceiling air outlet is mounted with the induction guide tube having the opening for introducing the air inside the ceiling on the outer peripheral surface. An adjustment tube connected to the tip of the air supply duct is slidably inserted into the and the intake port that connects the interior of the ceiling and the space inside the room is installed in the ceiling to reduce the amount of conditioned air to be transported. It is possible to achieve economical operation and reduce construction costs, and also to make the airflow distribution uniform and construct a highly efficient thermal environment. Further, it is possible to create a comfortable indoor environment by suppressing the generation of dew condensation at the ceiling outlet, preventing the ceiling surface from being soiled, and preventing the generation of drafts.
