DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stool such as a bench for a spectator seat or a chair in a large space building such as a dome, and more particularly to a heating stool having a heating function.

[0002]

2. Description of the Related Art Conventionally, as a bench having a heating function in a bench such as a spectator seat in a large space building such as a dome, for example, there is a stepped bench. this is,
As shown in FIG. 5, each step of the stairs formed of concrete or the like becomes a frame 2 constituting each bench 1, and a seating portion 3 formed of, for example, FRP is fixed on the frame 2. It is supposed to. The interior of each skeleton 2 constitutes a hot air duct 6 composed of a concrete duct having a space surrounded by concrete walls forming the skeleton 2 as a duct.

When the spectator sits on the seating portion 3, the frame 2 has a blowout opening 5 ′ of about 120φ at a position facing the vicinity of the calf of the spectator.
The hot air duct 6 of each bench 1 is connected to an air conditioner (not shown), and hot air is supplied from the air conditioner to each of the hot air ducts 6 so that hot air is blown from the air outlets 5 ′ and seated. By hitting near the calf of a spectator, the feet of the spectator can be warmed.

[0004]

However, in the above-mentioned conventional heating stool, since the warm air blown from the blower blows directly into the vicinity of the calf of the spectator, it is difficult to control the temperature. There is a problem that the position of the air outlet and the calf is shifted depending on the sitting style or the posture of the person, and a sufficient heating effect cannot be provided because the hot air is not blown to an accurate position.

The present invention has been made in view of the above-mentioned conventional problems, and provides a heating stool capable of providing a heating effect irrespective of a seating position, a sitting style, and the like of a seated person. It is intended to be.

[0006]

In order to achieve the above object, a heating seat according to the first aspect of the present invention supports a seating portion with a gap above a frame portion, and removes warm air from an air conditioner. After the air is blown toward the back surface of the seat portion, the air is guided to the vicinity of the front surface of the skeleton portion.

According to the present invention, the seating portion is supported on the frame portion with a gap therebetween, and for example, warm air from a hot air duct formed in the frame portion is applied to the seating portion at the upper portion of the frame portion. Air is blown from the formed blower port toward the seating portion. The blown hot air collides with the back surface of the seating portion, spreads in the gap between the seating portion and the frame portion, and is guided to the edge portion of the seating portion,
Air is blown from the gap between the seating portion and the frame portion. Therefore,
Since the range of the flow of hot air blown from the gap between the seating part and the frame is wider than the range of the flow of hot air blown directly from the air outlet, the seating position of the person sitting Even when the foot is displaced from a predetermined sitting position or the position of the foot is displaced due to the manner of sitting, etc., the warm air hits the feet of the seated person with a higher probability.

According to the present invention, when air blowing ports are formed in the skeleton at predetermined intervals in accordance with, for example, the width of the heating seat, hot air is supplied from the air conditioner to the hot air duct formed in the skeleton.
Hot air is blown out of the frame from the air outlet. Then, the hot air blown from the air outlet collides with the back surface of the seating portion, and the range of the flow of the hot air spreads, and spreads in the gap between the skeleton portion and the seating portion. Being guided,
It is blown to the front of the skeleton. Therefore, the range of the flow of the hot air guided by the air blowing guide and blown is wider than the range of the flow of the hot air blown directly from the blowing port. Therefore, even when the seated position of the seated person, or the position of the foot and the like is slightly deviated from the predetermined seating position, the warm air guided to the air blowing guide near the feet of the seated person is blown with a higher probability, Can give a heating effect.

Further, a heating seat according to a third aspect is characterized in that the air guide is formed over the entire width direction of the seating portion. According to the present invention, since the blowing guide is formed over the entire width direction of the seating portion, warm air is blown from the entire width direction of the seating portion. Therefore, no matter where the user sits on the seat, warm air is reliably blown to the feet of the seated person.
