DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning floor with a seat in a building such as a theater or a hall.

[0002]

2. Description of the Related Art Recently, it has been considered to use a double floor air conditioning system (underfloor air conditioning system) used in offices and the like as a method for effectively air conditioning only in the vicinity of seats in theaters and halls. Re that. With this double floor air conditioning system,
In theaters, halls, etc., where most of the floor is occupied by seats, it is not possible to secure enough space to place floor outlets so that people do not feel uncomfortable airflow. It is difficult to apply the exit as it is.

Therefore, it is conceivable that the seat itself has a function of blowing air for air conditioning, and for example, the one shown in FIG. 4 is known. In the figure, reference numeral 101 is a staircase floor, and a large number of seats 102 (only two are shown) are attached to the floor 101. The floor 101 is provided with an opening 103 corresponding to each seat 102,
The seat 102 is arranged at the position of the opening 103.

The seat 102 is provided with an internal passage 102A communicating with the opening 103, and the outlet of the internal passage 102A is an air outlet 102B. Then, the air conditioning air in which the room air of the secondary air is taken in as the primary air from the opening 103 is blown out into the room from the air outlet 102B, and the air conditioning air flows in the rear area of the person sitting on the seat 102. Passing and rising, it does not hit the person sitting in the rear seat 102, and the airflow of the air-conditioning air from the air outlet 102B hits the person sitting in the seats 102, 102 before and after that, and feels uncomfortable. It is prevented from waking up.

[0005]

However, in the conventional seat body, even if it is possible to prevent the air conditioning air from the air outlet 102B from hitting a person sitting on the seat 102 to feel an uncomfortable air flow, Since the air-conditioning air blowing function is incorporated in itself, a structure that integrates the seat 102 and the air outlet 102B is required.
It is necessary to design and manufacture 02, which makes the structure complicated and increases the cost.

Further, the seat construction and the air-conditioning construction cannot be separated from each other at the construction site, and the adjustment of the seat construction and the air-conditioning construction at the construction site becomes complicated. The present invention has been made to solve the above problems,
The purpose is to design and manufacture a special seat by providing the air outlet on the floor separately from the seat without making the air conditioning air from the air outlet feel uncomfortable for the seated person. Is to provide an air-conditioning floor with a seat having a simple structure.

[0007]

According to the first aspect of the present invention,
A floor portion, a seat attached to the floor portion and having a back portion inclined rearward, and an air outlet provided on the floor portion and arranged behind the seat so that the airflow of the air conditioning air strikes the back portion of the seat. And the outlet is inside the opening formed in the floor.
It is located below the floor and is configured as an opening.
It is characterized by having been done.

[0008]

[0009]

According to the first aspect of the invention, the blowout flow of the primary air is blown out from the blowout port, and a part or all of the blowout flow becomes air for air conditioning and hits the back part of the seat.

Since this conditioned air rises along the back of the seat, it flows into the extension area of the back of the seat and does not hit the person sitting in the seat. Further, the primary air is blown out as a blowout flow from the air outlet formed in the opening, and the indoor air (secondary air) is attracted and mixed with this primary air to become air for air conditioning.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 relate to an air conditioning floor with a seat according to an embodiment of the present invention.

In the drawings, reference numeral 1 is a staircase-like floor, and a large number of seats 2 (only two of which are shown) are arranged on the floor 1 at predetermined intervals. The seat 2 is composed of a seat portion 2A and a backrest portion 2B, and a back portion 3 inclined rearward is formed on the back surface of the seat portion 2A and the back surface of the backrest portion 2B.

Air outlets 4 are provided on the floor 1 in correspondence with the respective seats 2. The air outlets 4 are provided directly below the seat 2 so that the air flow of the air conditioning air strikes the back 3 of the seat 2. It is located and located.

The outlet 4 is arranged in the opening 5 formed in the floor 1, is formed into an opening that becomes thinner toward the tip, and is arranged below the floor 1A. Above the air outlet 4, at the same height as the floor surface 1A,
A slit member 6 is provided, an underfloor chamber 7 is formed below the air outlet 4, and an air volume adjusting damper 8 is provided in the underfloor chamber 7.

Therefore, as shown in FIG. 3, the blowout flow blows out from the outlet 4 constituted by the opening as the primary air K1, and the indoor air (K2, K2) (secondary air) is attracted to the primary air K1. ， Mixed to become air for air conditioning. That is, the left and right regions R shown by the dotted line of the outlet 4 by the primary air K1,
Since the pressure of R becomes low, the secondary air K2, K2 (indoor air) is drawn in, mixed with the primary air K1, and again comes out indoors.

This conditioned air hits the back portion 3 of the seat 2, and since the back portion 3 is inclined, it rises along the back portion 3 of the seat 2, flows into the extension region of the back portion 3 of the seat 2, and sits on the seat 2. It doesn't hit the person M.

According to an experiment on the flow of air for air conditioning, the following results are obtained. First, when the positions of the back 3 and the air outlet 4 were adjusted, the diffusion angle of the blowout flow was about 25 ° in the free jet zone (shown in FIG. 3), and when reaching the back 3, it contracted to about 10 ° and the air conditioning The working air flows along the inclination of the back portion 3, and the person M sitting in the seat 2 at the rear does not directly enter the jet area P of the air conditioning air.

Further, for the person M sitting in the front seat 2, if the air-conditioning air hits the bottom portion 2C of the seat 2,
Since a part of the air conditioning air reaches the feet and makes a draft feel uncomfortable, the position of the air outlet 4 is close enough to prevent the air conditioning air from hitting the bottom portion 2C of the seat 2. It is installed in the position.

Further, the recommended inclination angle of the back 3 is 2
It is said that 0 ° is good, and as the tilt angle increases,
The airflow of the air-conditioning air tends to reach the area of the seat 2 at the rear directly, causing a draft problem.

According to the above structure, the air outlet 4 is provided in the seat 2 while preventing the person M sitting in the seat 2 from feeling an uncomfortable air flow from the air outlet 4. Instead, it can be provided on the floor 1.

As a result, it is possible to effectively air-condition the passenger seats, and in a theater, hall, etc. having a large ceiling height, it is possible to predominantly air-condition only in the vicinity of the passenger seats, which saves energy compared with the conventional air-conditioning system. Can be achieved.

The integrated structure of the seat 2 and the outlet 4 can be avoided, and it is not necessary to design and manufacture a special seat, and the cost can be reduced. Further, since it is possible to separate the seat construction and the air conditioning construction at the construction site, it is possible to eliminate the complexity of the on-site adjustment of the seat compared to the conventional seat blowing method with an integrated air conditioning function.

Further, since fresh conditioned air is supplied from near the person M sitting in the seat 2, the efficiency of ventilation is high,
The freshness of the air near the seats can be maintained. Since the airflow outlet 6A is slightly raised above the floor surface 1A , the dust is prevented from being rolled up.

Further, as compared with the conventional air blowing method using the ceiling or the wall, the duct work can be significantly reduced and the cost can be reduced. Further, the blowout flow blows out as primary air from the blowout port 4 formed of an opening, and indoor air (secondary air) is attracted to this primary air,
Since the air is mixed and becomes air for air conditioning, it is possible to reduce the difference between the temperature of the air for air conditioning and the room temperature, and improve the comfort of living.

In this embodiment, the air outlet 4 is provided in the floor portion 1 corresponding to each seat 2, but the air outlet 4 is not necessarily provided corresponding to each seat 2. There is also a mode, for example, one air outlet 4 can be installed for two seats 2.

[0026]

As described above, according to the present invention,
The air-conditioning air from the air outlet can be provided on the floor portion without providing the air outlet for the seat while preventing the seated person from feeling uncomfortable air flow.

Therefore, the integrated structure of the seat and the outlet can be avoided, and it is not necessary to design and manufacture a special seat, and the cost can be reduced. Further, since it is possible to separate the seat construction and the air conditioning construction at the construction site, it is possible to eliminate the complexity of the on-site adjustment of the seat compared to the conventional seat blowing method with an integrated air conditioning function.

Further, the blowout flow is blown out as the primary air from the air outlet constituted by the opening, and the indoor air (secondary air) is attracted and mixed with this primary air to become the air for the air conditioning. The difference between the room temperature and the room temperature can be reduced, and the comfort of living can be improved.
