Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an underfloor air conditioning outlet disposed in a floor panel in an underfloor air conditioning system.

[Conventional technology]

Recently, in office buildings, etc., a space is formed under the floor, hot or cold air is supplied to this space, and this hot or cold air is blown into the room from the outlet formed on the floor surface, and the indoor air is heated. Underfloor air conditioning is used to provide air conditioning.

FIG. 7 shows a conventional underfloor air conditioning system, in which the air conditioner 11
The warm or cool air passes through a space 15 formed at the lower part of the floor panel 13 and is blown out into the room 19 from an underfloor air conditioning outlet 17 formed in the floor panel 13, whereby the room 19 is air-conditioned.

[Problem that the invention attempts to solve]

However, with such a conventional underfloor air conditioning outlet 17, it is not possible to appropriately control the outlet airflow even when the air conditioning conditions are completely different, such as when hot air is blown out in winter and cold air is blown out in summer. However, there was a problem in that there were limits to the improvement of the indoor environment.

[Purpose of invention]

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an underfloor air conditioning outlet that can easily control the airflow from the outlet grille.

[Means for solving problems]

The underfloor air conditioning outlet according to the present invention is an underfloor air conditioning outlet in which an outlet grill is arranged in an opening formed in a floor panel, and the outlet is arranged in the center of the opening and has teeth along the outer periphery of the lower surface. a jet angle adjusting member having a surface formed thereon; a plurality of guide vanes disposed surrounding the jet angle adjusting member; a transmission gear fixed to the inner ends of these guide vanes and meshing with the tooth surface; An airflow guide mechanism for changing the jetting angle of the airflow, which has a support pin fixed to the outer end of the guide blade and rotatably supports the guide blade, is provided below the blow-off grille.

[Effect of invention]

In this invention, an airflow guide mechanism that changes the jetting angle of the airflow is provided below the outlet grille, so that the airflow at the bottom of the floor panel is controlled by the airflow guide mechanism, and then the airflow is directed to the outlet grille. flows into the room from

That is, for example, in winter, the airflow guide mechanism is adjusted so that the airflow blowing angle is widened,
This directs the airflow toward the vicinity of the floor panel, while in summer, the airflow guide mechanism is adjusted to narrow the airflow outlet angle, thereby directing the airflow perpendicular to the floor panel. Ru.

[Example of idea]

Hereinafter, details of the present invention will be described with reference to an embodiment shown in the drawings.

1 and 2 show an embodiment of the underfloor air conditioning outlet of the present invention, and in the figures, reference numeral 21 indicates a free access type floor panel.

Below this floor panel 21, a floor slab 2
3 are arranged, and the space 25 between the floor panel 21 and the floor slab 23 is used as a chamber.

An upper part of a casing 29 is fixed to an opening 27 formed in the floor panel 21, and a blowout grill 31 having a concentric opening is arranged at the upper end of the casing 29.

Below this outlet grill 31, the outlet grill 3
An airflow guide mechanism 33 that changes the jetting angle of the airflow from the airflow guide mechanism 33 is arranged.

Further, a motor 3 is located below the airflow guide mechanism 33.
A fan 37 rotated by 5 is disposed.

3 and 4 show details of the airflow guide mechanism 33, and in these figures, reference numeral 39
1 shows an ejection angle adjusting member which is arranged at the center of the casing 29 and has a tooth surface 41 formed along the outer periphery of the lower surface.

A plurality of guide vanes 43 are regularly arranged surrounding this jet angle adjusting member 39.

Inner pins 45 are fixed to the inner ends of these guide wings 43, respectively.
The tooth surface 41 of the ejection angle adjusting member 39 is fitted with
A transmission gear 47 that meshes with is fixed.

One end of the inner pin 45 is connected to the jet angle adjusting member 39
It is rotatably inserted into a support member 49 that abuts the lower surface of the. A bar 51 is fixed to the lower surface of the support member 49, and the bar 51 is supported by the casing 29 via a stay 53.

On the other hand, a support pin 55 is provided at the outer end of the guide feather 43.
is fixed, and the other end of this support pin 55 is
It is rotatably supported by the casing 29.

In the underfloor air conditioning outlet configured as described above, the airflow guide mechanism 33 for changing the jetting angle of the airflow from the outlet grille 31 is provided below the outlet grille 31, so that the floor panel 2
After the direction of the airflow in the lower part of the airflow is controlled by the airflow guide mechanism 33, it flows into the room from the blow-off grille 31.

That is, in the underfloor air conditioning outlet configured as described above, warm air or cold air supplied to the space 25 formed between the floor panel 21 and the floor slab 23 is heated by the fan 37 rotated by the motor 35. After being drawn into the casing 29 by the suction force, the guide blade 4 of the airflow guide mechanism 33
3 and is ejected into the room from the blow-off grill 31.

In the underfloor air conditioning outlet configured as described above, for example, in winter, the blowout angle adjusting member 39 of the airflow guide mechanism 33 is manually rotated in the direction of arrow A in FIG. As a result, the guide vane 43 falls down as shown in FIG. 5, and the blowing angle of warm air is adjusted to widen, thereby directing the warm air toward the vicinity of the floor panel 21.

On the other hand, in the summer, the jet angle adjustment member 39 of the airflow guide mechanism 33 is manually adjusted to the arrow B in FIG.
As a result, the guide vane 43 stands up as shown in FIG. 6, and the blowing angle of the cold air is adjusted to be narrower.
1 in a direction perpendicular to 1.

In other words, with the underfloor air conditioning outlet configured as described above, when the air conditioning conditions are different, such as when hot air is blown out in winter and cold air is blown out in summer,
By adjusting the airflow guide mechanism 33, it becomes possible to easily control the airflow blown out from the blowout grille 31.

In addition, in the embodiment described above, the airflow guide mechanism 3
A fan 37 rotated by a motor 35 below the
Although an example in which fans are arranged has been described, the present invention is not limited to such an example, and the present invention is not limited to such an example.
Of course, the present invention can also be applied to the case where 7 is not arranged below.

[Effect of idea]

As described above, in the present invention, an airflow guide mechanism is provided below the blowout grille to change the blowout angle of the airflow from the blowout grille, so the blowout angle adjustment member can be manually rotated to It becomes possible to arbitrarily adjust the airflow from the blow-off grille, and to easily control the airflow from the blow-off grille, thereby providing a comfortable indoor environment both during cooling in the summer and heating in the winter.
