Abstract

(57) [Summary] (Modified) [Purpose] To provide a heat-exchange outer garment with good cooling or heating efficiency. [Structure] A hollow portion 7 is formed by front and back cloths 2 and 3, and an air supply pipe 8 for supplying cool air or warm air is provided in the hollow portion, and an injection port 6 for discharging the cool air or warm air to the back cloth 3. In the heat exchange outer garment provided with, a non-breathable heat insulating material is used for the outer cloth 2. [Effect] Since the cloth made of the heat insulating material is used as the outer cloth, heat exchange of the air in the hollow portion due to the ambient temperature can be prevented. Therefore, the worker or the like can be efficiently cooled or heated. Further, since the surface cloth is not provided with an exhaust port, the cool air or warm air sent to the hollow portion from the air supply pipe is not promptly transferred to the outside and can be efficiently cooled or heated.

Description

[Detailed description of the device]

[0001]

[Technical field of invention]

 The present invention relates to a heat exchanging outer garment, and more particularly to an outer garment having a heat exchanging function, which is worn by workers who work in places with high or low temperatures.

[0002]

[Prior art and problems]

 Conventionally, as this type of outer garment, as shown in FIGS. 3 and 4, a large number of places are adhered to the front and back cloths 2 and 3 of each body 1 at required intervals, and exhaust ports 5 are attached to these adhered parts 4, respectively. It has a structure provided. The back cloth 3 is provided with an injection port 6 communicating with the inside of the body 1, and an air supply pipe 8 for sending cold air or warm air is provided in a hollow portion 7 formed by the front and back cloths 2, 3. (Jitsuko Sho 44-18961).

With such a structure, when the worker wears such an outer garment and sends cool air or warm air from the air supply pipe 8 to the hollow portion 7, the cold air or the like expands the hollow portion 7. At the same time, cold air or the like blows out from the injection port 6 communicating with the hollow portion 7 to the inside of the body 1 to cool or heat the wearer. Cold air or warm air blown inside the outer garment is discharged to the outside from the discharge port 5.

Due to the above-mentioned structure, the worker can always work at a comfortable temperature by this heat exchange regardless of the outside air temperature.

[0005]

[Problems solved by the device]

 However, the outer garment having the heat exchange function described above has the following drawbacks.

[0006] Cold or warm air is discharged from the outlet 6 to the outside through the outlet 5 before the cooling or heating effect is exerted on the surface of the worker's body, resulting in poor cooling or heating efficiency.

“Since the outer cloth 2 having a double structure is simply a non-breathable material, the cold air or warm air sent to the hollow portion 7 may be warmed or cooled by the external environment temperature. , The cooling or heating efficiency of workers deteriorates.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a heat-exchangeable outer garment with good cooling or heating efficiency.

[0009]

[Means for solving problems]

 The present invention has been made in view of the above problems, and a hollow portion is formed by a front and back cloth, and an air supply pipe for supplying cool air or warm air is provided in the hollow portion, and the cold air or warm air is supplied to the back cloth. In a heat exchange outer garment provided with an ejection port for discharging, a non-breathable heat insulating material is used for the outer cloth.

[0010]

【Example】

 FIG. 1 is a front view of a heat exchange outer garment of the present invention, and FIG. 2 is a partial cross-sectional perspective view thereof. As is apparent from these figures, the outer garment of the present invention has a hollow portion formed by front and back cloths 2 and 3. 7 is formed, and a plurality of injection ports 6 communicating with the hollow portion 7 are formed in the back cloth 3. An air feed pipe 8 is connected to the hollow portion 7, and the air feed pipe 8 can feed cold air or warm air to the hollow portion 7.

A muffler 9 is attached to the end of the air supply pipe 8 as described above so as to muffle the noise in the air supply.

In the heat exchange outer garment having such a structure, in the present invention, a non-air-permeable heat insulating cloth is used as the outer cloth 2. As such a heat insulating cloth, for example, a foam having closed cells such as a chloroprene foam, a polyethylene foam, or a non-breathable quilting cloth can be used.

As the back cloth 3, it is possible to use an ordinary non-breathable synthetic fiber cloth or the like.

The outer garment of the present invention as described above does not have the discharge port 5 as in the conventional case. This is because the temperature control of cold air or warm air has advanced remarkably compared to the conventional one, and it becomes possible to keep the temperature of the worker's body constant and shut off the convection of the cold air or warm air. This is because it is no longer necessary to provide the adhesive section 4 or the discharge port 5. Rather, it has been found that not providing the discharge port 5 has better performance in terms of cooling or heating efficiency.

Further, since the cloth made of the heat insulating material is used as the outer cloth 2, the cold air or the warm air supplied to the hollow portion 7 is not warmed or cooled by the environmental temperature, so that the work can be performed. The cooling or heating efficiency of the person is further increased.

Further, in this embodiment, the muffler 9 is provided, but since the outer garment according to the present invention does not have the adhesive portion, a large noise is generated during air supply or when air supply is stopped. There is a risk of Such noise may hinder the contact with the operator, and it is desirable to prevent it. Therefore, the muffler 9 is provided at the end of the air supply pipe 8.

[0017]

[Effect of the device]

 As described above, according to the outer garment of the present invention, since the cloth made of the heat insulating material is used as the outer cloth, heat exchange of the air in the hollow portion due to the ambient temperature can be prevented. Therefore, the worker or the like can be efficiently cooled or heated.

Further, since the outlet is not provided in the outer cloth, the cool air or warm air sent to the hollow portion from the air supply pipe is not quickly discharged to the outside, and efficient cooling or heating is possible. .

Further, by providing a muffler at the end of the air supply pipe, there is an advantage that noise caused by air supply or air supply stop can be prevented.
