Two blast pipes 2a, 2b are connected respectively to the supply opening 9 and the exhaust opening 10, one blast pipe 2a is connected by an air duct 15a to the air-conditioner air feeding side of an air conditioning system 11 surrounded by a surrounding member 3a and is thereby used as the supply pipe of the air conditioner, while the other blast pipe 2b is used as an exhaust pipe which returns to the air conditioning system 11 via an air duct 15b. Therefore, the seats 4 of numerous chairs 1 can be cooled and heated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair heating and cooling device.

[0002]

2. Description of the Related Art Conventionally, a device for cooling and heating a seat portion of a chair by cooling and warming air is provided in Japanese Utility Model Publication No. 6-19615.

[0003]

In the conventional cooling and heating apparatus described above, the cooling and heating air duct is built in the seat portion, the structure is complicated, and the cooling and heating air is discharged. In order to obtain the cooling and heating effect, a cooling and heating device with a large capacity is required, which causes a problem of cost increase.

In view of the above conventional problems, an object of the present invention is to
An object of the present invention is to provide a low-cost chair air-conditioning device that can cool and heat the seats of a large number of chairs by means of an air-conditioning device with a simple structure and small capacity.

[0005]

In order to achieve the above-mentioned object, the structure of the present invention is such that a plurality of chairs for one person, each of which has a cavity portion in the seat portion, are continuously connected in a bench shape, and support legs are provided. The two blower pipes that also serve as the chairs are supported in parallel with the direction in which the plurality of chairs are continuously arranged, and the cavity portion of the seat portion and the two blower pipes are communicated with each other. One of the blower pipes is connected to the cool and warm air blower side of the cooling and heating device to serve as a supply pipe for cool and warm air, and the other blower pipe is a discharge pipe that recirculates to the cooling and heating device.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a chair in which a plurality of chairs for one person are connected in a bench shape. Reference numerals 2a and 2b denote two blower pipes which are supported on the support legs 3b in parallel with the direction in which the plurality of chairs 1 are continuously arranged. 3a is a cooling and heating device 1 described later
1, which is an enclosure member and is arranged on the lower surface of the chair 1.

As shown in FIG. 2, the chair 1 has a seat portion 4 provided with a cavity portion 6. When the chair 1 is molded from plastic, the cavity 6 of the seat 4 and the cavity 7 of the backrest 5 are isolated from each other when the cavity 7 is also formed on the backrest 5 due to the molding. To form the partition wall concave portion 8,
It is desirable to prevent the cold and warm air supplied into the cavity portion 6 of the seat portion 4 from escaping to the cavity portion 7 of the backrest 5 by the configuration described later to prevent the cooling and heating efficiency of the seat portion 4 from being lowered.

As shown in FIG. 3, a cold-air supply port 9 and a discharge port 10 are provided on the lower surface of the seat portion 4 having the cavity portion 6.

The two blower pipes 2a and 2b are provided with holes 12 and 13 for connecting the cooling / warming air supply port 9 and the discharge port 10 on the lower surface of the seat portion 4, and the two air blowers are provided. Tube 2a,
When the chair 1 is installed on the 2b through the support bar 14, the cold and warm air supply port 9 and the discharge port 10 on the lower surface of the seat portion 4 are fitted and connected to the holes 12 and 13.

One of the two blower pipes 2a, 2b is connected to the cool / warm air blower side of the cooling / heating device 11 surrounded by the enclosure member 3a by a wind guide pipe 15a for cooling and warming air. It is used as a supply pipe, and the other blower pipe 2b is a wind guide pipe 15b.
The exhaust pipe is returned to the cooling and heating device 11 via the.

In the embodiment shown in the drawing, the air-conditioning system of the diffusion type is used, but in the centralized air-conditioning system, two pipes 2a, 2b are connected to the lower part of the floor via air guide pipes 15a, 15b. Connecting.

Since the present invention has the structure as described above, the cooling / heating air is sent from the cooling / heating device 11 to the one blower pipe 2a through the wind guide pipe 15a, and the cavity portion of the seat portion 4 of each chair 1 is sent. 6 to heat and cool the seat 4.

At this time, when the cavity portion 7 is also formed on the backrest 5 as shown in FIG. 2, the cavity portion 6 of the seat portion 4 and the cavity portion 7 of the backrest 5 are separated by the partition wall recess 8. Therefore, the cold and warm air supplied into the cavity 6 of the seat 4 prevents the backrest 5 from escaping to the cavity 7, and the cooling and heating efficiency of the seat 4 does not decrease.

The cold and warm air that has been used for cooling and heating the seat portion 4 supplied to the cavity portion 6 is returned to the cooling and heating device 11 from the other blower pipe 2a through the air guide pipe 15b.

Therefore, since the cooling / warming air is not released to the atmosphere, a large cooling / heating effect can be obtained, and the cooling / heating device having a small capacity can perform sufficient cooling / heating.

By installing the chair 1 on the two air ducts 2a and 2b via the support bar 14, the air-conditioning air supply port 9 and the air-exhaust port 10 on the lower surface of the seat portion 4 have two air vents. Tube 2
Since they are fitted and connected to the holes 12 and 13 of a and 2b, a complicated structure in which the cooling / heating blower pipe is built in the seat is not necessary.

[0017]

As described above, according to the present invention, it is possible to provide at low cost a cooling and heating apparatus for a chair that can cool and heat the seat portions of a large number of chairs by an cooling and heating apparatus having a simple structure and a small capacity. have.
