In the cooling fluid circulation path 65, the cooling fluid circulates in such a flow.

A cord 69a of the pump 69 is passed through the insertion hole 47, enters the inside of the pocket 29, and is pulled out from a small opening 29c on the left side. Two insertion type guide portions 53, 53 are attached to the upper side of the insertion type guide portion 27 on the left front body 7, and the cord 69a pulled out is attached to the insertion type guide portions 53, 53 and the insertion type guide portion. 27 and detachably connected to a controller 71 housed inside the pocket 25 .

The controller 71 has an external shape as shown in FIG. 6, and has an ON/OFF switch 71a on its outer surface. Power supply is stopped. The lamp 71b lights up while the power is being supplied. In addition, a USB connector 71c is provided for charging from the outside and supplying power to the outside. Since the controller 71 is housed in the pocket 25 of the left front body 7, it is easy to operate even when the cooling vest 1 is worn.
The controller 71 contains a battery and a microcomputer and is connected to the switch 71a and the motor of the pump 69. In cooperation with software, an operation mode execution function for controlling power supply to the motor is realized, and the pump 69 is operated. Operate.

In the operation mode execution function, a desired operation mode can be selected from a plurality of operation modes, and when the switch 71a is pressed, the operation mode is performed for 3 hours as measured by a timer. At that time, when the switch 71a is pressed once, the continuous operation mode is selected. When the switch 71a is pressed twice, the intermittent operation mode (1) of operation for 1 minute→stop for 1 minute→operate for 1 minute→stop for 1 minute→……is selected. When the switch 71a is pressed three times, the intermittent operation mode (2) of operation for 20 seconds→stop for 1 minute and 30 seconds→operate for 20 seconds→stop for 1 minute and 30 seconds is selected. That is, the operation mode execution function includes an intermittent operation function for intermittently operating the pump 69 .
If the switch 71a is pressed long during operation, the operation ends.

As shown in FIG. 7, the plate-like cold insulator H is taken in and out through an opening 55c of the accommodating portion 55. As shown in FIG. The cold insulator H is composed of a flat container Ha in which a freezeable liquid is enclosed.
As shown in FIG. 8, the flat cold insulator H can be accommodated in the interior of the accommodating portion 55 in a standing posture. It should be noted that the standing posture is not limited to being strictly upright, but includes the case of being leaned against the inner surface of the housing portion 55 and lying down. The cold insulator H is accommodated in a standing posture due to the horizontal size of the accommodating portion 55 .
After housing the cold insulator H in the housing portion 55, the fastener 56 is closed. That is, the ridges and grooves of the fastener 56 are aligned and the ridges are fitted into the grooves. Further, the pressing member 60 is slid into the groove 60c of the pressing member 60 so as to match the right end or the left end of the upper end of the housing part 55, and the pair of pressing pieces 60a and 60b are elastically deformed in the widening direction. The upper end of the housing portion 55 is inserted. As a result, the fastener 56 is pressed in the closing direction by the pair of pressing pieces 60a and 60b. Therefore, it is possible to prevent the opening 55c from being opened carelessly.
The size of the cold insulator H is 150 mm to 250 mm in width, 200 mm to 300 mm in height, and 10 mm to 30 mm in thickness.

Since the storage portion 55 of the cooling vest 1 stores the flat cold insulator H, no bulging portion is formed on the back side of the person wearing the cooling vest 1, and when the back is attached to the wall or the backrest of a chair, etc. Disturbing inconveniences can be avoided.
When the cooling fluid circulation path 65 is formed as described above by the operation of the pump 69, the water W that has flowed into the housing portion 55 forms water droplets D, hits the outer surface of the flat cold insulator H, and falls while sliding down. To go. In the process of falling, heat is taken away and cooled, and it joins the lower puddle. The cooled puddle below is returned to the tube 67 side by the suction action of the pump 69 .
The water W only needs to be at a level that does not allow air to enter the cooling fluid circulation path 65, that is, the level of the water W contained in the housing portion 55 is higher than that of the lower connecting portion 55b. It is planned. Moreover, the durability of the cooling vest 1 can be improved by reducing the weight.

Further, as described above, it is possible to intermittently operate the pump 69, and since the water droplets D do not flow into the storage portion 55 at the timing of stopping during the intermittent operation, the intermittent operation also reduces the temperature of the cold insulator H. Slows the speed at which frozen liquids thaw.

On the other hand, the water W just cooled by the cold insulator H is considerably cold, and since the tube 67 is exposed from the garment main body 3, when the tube 67 through which the water W is circulated is touched, it is relatively strong. I feel cold. However, when the freshly cooled water W is constantly circulating, the sensation becomes dull and the coldness becomes weaker.
In such a case, when the water W is warmed to a certain extent, it is cooled, and when the water W is warmed to a certain extent, it is cooled again. You will be able to feel
Therefore, if the optimum intermittent operation mode is selected, it also has the effect of providing comfortable coolness for a moderately long period of time. In the above intermittent operation mode (2), the stop period is relatively long at 1 minute and 30 seconds, and when the coldness is exhausted to the point where a slight amount of coldness remains, the coldness can be instantly felt strongly again. It's like

Since the cooling vest 1 has a lightweight structure, it can be provided at a low cost and is not bulky. Therefore, it does not interfere with the movement of the wearer when worn.
Moreover, since the meandering portion 67a of the tube 67 is provided not only on the back portion 5 but also on the front portions 7 and 9, it is possible to cool not only the back but also the chest area when worn. The garment main body 3 is configured flexibly, the cooling vest 1 deforms along the shape of the wearer's body, and the tube 67 can also move to some extent while pulling the insertion-type guide portion 53, so that the meandering portion 67a can be applied to the back and chest. The cooling effect can be used without waste by contacting the
The cloth and tube 67 constituting the clothing body 3 of the cooling vest 1 are not special and can be obtained at a low cost, and sewing them to make the cooling vest 1 is a time-consuming task. It is also advantageous in terms of cost because it does not require special equipment or equipment.

9 and 10 show a cooling vest 101 according to a second embodiment.
This cooling vest 101 has almost the same configuration as the cooling vest 1, but it is designed to be able to use a PET bottle P in which the contents such as water are frozen, and only the characteristic difference is explain.
A large circular hole 155a is formed in one surface of the housing portion 155 . Holes of the same size are also formed in bag cloth 129b of pocket 129, and the edges of the holes are aligned and overlapped. Accordingly, the housing portion 155 is connected to the pocket 129 via the mouthpiece 157 . A cap 161 is connected to the mouthpiece 157 via a string 159 , and when the male threaded portion of the lid 161 is screwed into the female threaded portion of the mouthpiece 157 , the opening of the accommodating portion 155 is closed. A packing 163 is fitted in the lid body 161 to prevent the liquid from leaking.
The base 157, the cord 159 and the lid 161 are integrally molded of plastic. The cord 159 is thin and therefore flexible, but the base 157 and the lid 161 are rigid to some extent.
In the cooling vest 101, the PET bottle P can be taken in and out of the housing portion 155 through the hole 155a, and either the PET bottle P or the flat cold insulator H can be selected.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment. included.
Also, the manner and density of the tube 67 to be laid may be optimized according to the body size of the garment body.
Closing means for closing the upper end opening of the container is not limited to the above-mentioned fasteners and clamps, and may be of any other construction as long as it can close the opening of the container so that water does not leak from the opening of the container. good too.
