Abstract

PROBLEM TO BE SOLVED: To set an air conditioning temperature while sitting by circulating and supplying cold and hot water from a supplier to a radiator disposed inside a chair. SOLUTION: In a winter season, when the hot water is prepared in a cold and hot water supplier and the hot water is circulated and supplied through a circulation pipe 9 to the radiator 6 for air conditioning, the radiator 6 is heated and radiates heat. The heat passes through an air permeable plate 11, rises and warms the calves of a person sitting on a seat part 2. When it is too hot, by controlling a hot water flow rate by the control switch 18 of a flow rate adjusting valve 17 which is a temperature adjustment part, his/her desired temperature is set. On the other hand, in a summer season, when the cold water is prepared in the cold and hot water supplier and the cold water is circulated through the circulation pipe 9 to the radiator 6 for air conditioning, the radiator 6 is turned to a cooled state. When a cooling switch 15 is operated, since air inside a spatial inner part 5 where the radiator 6 for air conditioning is installed is sucked by a through flow fan 14, outdoor air made to flow in from the air permeable plate 11 is heat exchanged with the radiator, turned to cooled air and is forcedly ejected from a cooled air ejection port 12.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a chair equipped with an air conditioner for air conditioning and heating, and an air conditioner for adjusting the air conditioning of a spectator hall using the chair.

More specifically, the present invention relates to a chair provided with a heating / cooling air conditioner provided on the chair itself, and also provided with a cooling / heating air conditioner which allows the chair user to set his / her desired temperature as needed. Is. In addition, by using the chair of the present invention in a venue such as an opera theater or a movie theater where a large number of spectators are accommodated, the comfort of being able to freely select the cooling / heating air conditioning that suits the individual temperature of the spectator is of course provided. (EN) An air conditioner that can save energy and does not require a large-scale air conditioner as a cooling and heating air conditioner in a venue, and can effectively reduce initial costs and running costs.

[0003]

2. Description of the Related Art Conventionally, many chairs have a function as a heating device. For example, in a train seat,
In cold seasons such as winter, the heating system was operated as necessary to obtain a warm environment. However, there is no chair equipped with the function of an air conditioner,
In hot seasons such as summer, there was no choice but to obtain coolness with a mere fan such as a fan placed on the ceiling.

In a venue where a large number of people are accommodated in a building to perform a play, a movie, etc., a large number of chairs are vertically and horizontally arranged on the floor surface to form spectator seats. If there is an orchestra box or a movie screen on the floor, the floor should be gradually raised toward the rear to make it easier for the audience to see the front side of the stage. It is assumed that many are arranged vertically and horizontally.

The air-conditioning equipment at such a venue is generally equipped with a large-capacity air-conditioning equipment for cooling and heating the entire venue, and as a result, a large-capacity air volume is used.
Especially in the air conditioner, the cold air outlet is installed near the ceiling of the venue, especially in the rear part of the venue in many cases, but since the specific gravity of the cool air is heavy, the cool air blown into the venue from the rear part of the venue is , Slowly drifting forward, so the cold air acts as an air curtain. Further, the temperature control of the heating and cooling is set at the temperature set by the facility manager of the venue, and if it is not set to the temperature desired by the individual, it is the current situation that there is only a certain amount of patience.

[0006] In such a conventional venue having a large-capacity air-conditioning facility, the air-conditioning facility may not be usable when singing with a live voice such as an opera, that is, when a singer with a low voice sings, the venue Due to the air curtain effect of the cold air floating inside, the sound may not be heard sufficiently to the upper back of the spectator seats. Due to the problem that this sound has not reached, it is not possible to use the air conditioner in the venue in the hot summer. There's a problem. Such inadequate venue equipment is also a factor that has hindered the spread of classical music.

[0007] In particular, since an opera is usually sung in a foreign original language, Japanese translated subtitles are usually installed on the upper surface of the stage or on the left and right sides of the forehead, even if the audience cannot understand the original language. You can understand the content of acting by reading. However, such subtitles pose a problem that for those who are seated near the stage, trying to read the subtitles does not allow them to fully see the important stage performance. Furthermore, for the conductor's position in the orchestra box in front of the stage, there is a problem that the subtitles on the left and right flicker and the attention is distracted. However, the current situation is that ordinary venues have not been set up in consideration of the performance of such operas, including the air conditioning system.

[0008] Also, during the performance, the lights in the venue are usually dim, and it is very difficult for those who arrive late to the performance to reach the reserved seats in the dim venue, and the guides who are waiting at the venue. There was also a problem that you couldn't sit in the reserved seat without going through.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides an air conditioner capable of setting a heating / cooling temperature according to one's preference while sitting while sitting in a chair. .

Further, in the venue, each person can adjust the comfortable temperature within an arbitrarily small range, has a large-scale air-conditioning facility, and does not need to heat and cool the seats where no one is sitting, so that the running cost can be greatly reduced. Can be provided.

Further, since the air curtain function is not generated in the hall, the sound from the stage can be echoed to the rear seats without being interrupted on the way.

In addition, even if the inside of the venue is a little dark, it is possible to easily reach the reserved seat, and it is possible to easily see the character information such as the performance contents of the stage on the back wall of the seat back and the back of the seat. To provide a device that can

[0013]

An air conditioner for a chair according to the present invention has a radiator for cooling and heating arranged inside the chair, and chilled water or hot water is circulated to the radiator from a cold / hot water supply device as needed.

Embodiments of the present invention will be described with reference to the drawings.

1 and 2 show an embodiment of a single chair 1 of the present invention, which comprises a seat portion 2 and a backrest portion 3.
And the armrests 4 horizontally arranged on both sides of the seat 2, and the external shape thereof is as shown in the drawing.

A cooling / heating radiator 6 (fan coil unit) is provided in the interior 5 of the space formed below the seat portion 2. The radiator is a heat radiating plate group 7 in which a plurality of aluminum plates having good heat conductivity are arranged side by side with an interval.
.. and a meandering tube 8 that penetrates the heat dissipation plate group and is bent into a plurality of lines.

Hot water is made to flow through the meandering pipe 8 arranged in the radiator 6 for heating and cooling during heating and cold water during cooling, and these hot water or cold water is a cold / hot water supplier (water chiller) not shown. It is supplied by a circulating pipe 9. The circulation pipe is heat-insulated around the pipe so as not to exchange heat with the outside air in the middle of the pipe. Further, a flow rate adjusting valve 17 capable of varying the flow rate by controlling energization is provided at the connecting portion between the radiator 6 and the circulation pipe 9 so that the flow rate of hot water flowing from the cold / hot water supply device can be adjusted. The flow rate adjusting valve 1
The control switch 18 of No. 7 is formed diagonally below the seat 2.

A ventilating plate 11 having air permeability so as to close the front opening of the interior space 5 is detachably mounted on the lower chair front portion 10 located below the seat portion 2 by screwing or the like. ing. The ventilation plate is installed so that the calves of the legs face each other when a person is seated on the seat.

Reference numeral 12 denotes a cool air discharge port projectingly formed on the upper surface of the armrest portion 4, which is formed in each of the left and right armrest portions, and the cooling and heating radiator 6 is installed through the inside of the left and right armrest portions 4, 4. The duct 13 leading to the interior 5 of the space is connected.

A through-flow fan 14 (cross flow fan) is provided inside the duct 13, and the cooling switch 15 mounted on the upper part of the front wall of the armrest 4 is energized to drive or stop the rotation. I am able to do it.

The cold air discharge port 12 is formed in a spherical shape, and a slit 16 is formed in a part thereof, and the direction of the slit 16 is arbitrarily set by rotating the spherical main body left and right. I am able to do it. That is, a person seated on the chair 1 can manually select the wind direction by rotating the spherical body so that the wind direction is toward him or his face.

In such a structure, when hot water is produced by a cold / hot water supplier in winter and hot water is circulated and supplied to the cooling / heating radiator 6 through the circulation pipe 9, the radiator 6 is heated and radiates heat. The hot air passes through the ventilation plate 11 and rises, warming the leg calf of the person sitting on the seat 2. If it is too hot, the flow rate control valve 17, which is the temperature control unit
It is possible to set the desired temperature by controlling the flow rate of hot water with the control switch 18 of.

On the other hand, in the summer, cold water is produced by the cold / hot water supply machine, and the radiator 6 for cooling / heating is provided through the circulation pipe 9.
When cold water is circulated through the radiator 6, the radiator 6 is cooled. If the seated person wants to cool the air, by operating the cooling switch 15 which is a temperature adjusting unit provided in the armrest portion 4, the cross-flow fan 14 in the duct 13 is rotationally driven to suck the air in the space 5 inside. The cold air is forcibly discharged from the cool air discharge port 12. That is, since the air inside the space 5 where the cooling / heating radiator 6 is installed is sucked by the cross-flow fan 14, the outside air that has flowed in from the ventilation plate 11 exchanges heat with the radiator 6 to become cooled air, and cool air is discharged. Exit 12
Is discharged from. As described above, the discharge cold air can be obtained by rotating the spherical body provided at the cool air discharge port 12 and directing the slit 16 in any direction. A filter (not shown) can be detachably polymerized on the ventilation plate 11 as needed, and the filters are overlapped to prevent dust from being sucked in, especially during cooling.

Although the case where the chair 1 is used alone has been described above, an example in which a large number of chairs are used in a movie theater, a theater, or an opera hall provided with an orchestra box will be described.

In general, in a venue accommodating a large number of spectators, an orchestra box or the like is installed in the front part of the venue and in front of the stage, and a plurality of chairs, which are the seats behind the stage, are arranged in the lateral direction. They are arranged side by side, and there is a space 19 at the front and rear, and they are arranged in a column so that the rear gradually becomes higher. The front and rear space 19 becomes a passage for a person to pass in front of a seat already seated in order to take a designated seat, and the seat back gradually becomes higher when a seated person is behind the venue. Is designed so that you can see the stage well.

The chair 1'for use in the venue has at least the following functions in addition to the functions mounted on the chair 1 for use alone.

Of the back wall 20 of the backrest 3 of the chair 1 ',
Particularly, a cold air outlet 21 is formed at a position facing the vicinity of the upper half of the occupant of the rear seat.
