Description

  TECHNICAL FIELD The present invention relates to a cooling device for a cooling garment and a cooling garment equipped with the same.

Cooling garments have been proposed that can cool the body without assuming sweating of the wearer.
Specifically, a water storage tank is mounted on the shoulder, one end of a water supply hose is connected to the water storage tank, and then the middle part of the water supply hose is meandered by a body part, and then the other end of the water supply hose is connected. Is connected to the water storage tank.
In addition, a pump is interposed in the water supply hose, and by driving this pump, the cooling water in the water storage tank is circulated into the water storage tank, one end, the middle part, the other end of the water supply hose, and the water storage tank. (For example, Japanese Patent Application Laid-Open No. H11-163873 is similar to the prior art.)

  A water supply hose provided with a cooling water supply part and a cooling water branch part; a pump for supplying cooling water from the cooling water supply part of the water supply hose to the cooling water branch part; The water branching section, one end side water supply section and the other end side water supply section are connected, and, provided with a plurality of water distribution hoses between the one end side water supply section and the other end side water supply section became a water discharge section, The diameter of each of the water diversion hoses is smaller than the diameter of the water supply hose, and the water diversion hose has an outer peripheral portion orthogonal to a longitudinal direction of the water diversion hose. There has also been proposed a cooling device for a cooling garment having a configuration in which a plurality of water passage holes having a smaller opening area than the opening areas of the one end side water supply portion and the other end side water supply portion of the hose are formed. For example, Patent Document 2 listed below is a similar prior document. ).

JP-A-2017-20140 Japanese Patent No. 6284090

First, in the former Patent Document 1, the water supply hose has water holes formed at predetermined intervals from one end to the other end.
Therefore, when the pump is driven and the cooling water in the water storage tank is circulated into one end, the middle, and the other end of the water supply hose and into the water storage tank, some of the cooling water is supplied to the water supply hose through hole. When the air flows out of the tub, wets the clothes, and the wind passes through the area, the heat of vaporization is taken away, and as a result, the body can be cooled.
In other words, the cooling water flowing out of the water hole of the water supply hose is vaporized without assuming sweating of the wearer, and the body can be cooled by the heat of vaporization.

However, in such a conventional configuration, a circulation path (water storage tank, one end, middle part, other end, water storage tank) of a water supply hose having one end and the other end connected thereto is formed in the water storage tank. Therefore, the load as a pump is large, and the power consumption is large.
Further, when the opening area of the water supply hole of the water supply hose is increased, a large amount of cooling water in the water storage tank flows out from the water supply hole of the water supply hose, and as a result, a long-time cooling operation cannot be performed. Therefore, the opening area of the water hole is reduced, but in order to allow a part of the circulating water to flow out of the small water hole, the pressure of the pump must be increased. Therefore, the power consumption of the pump becomes a problem.
In addition, if the pressure of the pump is high and the opening area of the water hole is small, the cooling water vigorously jumps out of the water supply hose from the water hole, so that a preferable cooling operation cannot be performed.

On the other hand, in the latter patent document 2, the pump only needs to send the cooling water from the cooling water supply part of the water supply hose to the cooling water branch part, so that the power consumption can be reduced.
Further, the cooling water sent to the cooling water branch of the water supply hose flows into the water separating hose from the water supply hose on one end side of the plurality of water separating hoses connected to the cooling water branch, and then flows into each of the water separating hoses. It flows out from the plurality of water holes provided in the hose, and an appropriate amount of cooling water can be supplied to a wide area of the body, and as a result, the cooling effect is high.

  However, in the latter Patent Document 2, since the water distribution hose itself has a small diameter and the water holes formed in the outer circumference thereof are also extremely small, for example, a state in which a large amount of air exists in the water distribution hose. In other words, in the early stage of operation, until the air is expelled, cooling water flows out from the water hole near the water supply part on one end side of the water distribution hose, but from the water hole located farther than that. It is also assumed that a situation in which the cooling water does not flow sufficiently occurs.

  It is an object of the present invention to allow cooling water to flow from a wide portion of a water distribution hose from an early stage of operation, thereby enhancing a cooling effect.

  In order to achieve this object, a cooling device for a cooling garment of the present invention comprises a cooling water supply section, a water supply hose provided with a cooling water branch section, and a cooling water branching section from the cooling water supply section of the water supply hose. A pump that supplies cooling water to the unit side, a plurality of water distribution hoses to which at least one end side water supply unit is connected to the cooling water branch part of the water supply hose, and a control unit connected to the pump, A switch connected to the control unit, which activates the pump, and an operation unit connected to the control unit, which adjusts the supply power of the cooling water by the pump to at least three stages: small, medium, and large; A battery that supplies power to the pump, wherein the diameter of each water-dividing hose is smaller than the diameter of the water-feeding hose, and at the outer peripheral portion orthogonal to the longitudinal direction of each water-dividing hose, In front of this diversion hose A plurality of water passage holes having an opening area smaller than an opening area of the one end side water supply unit are formed, and the control unit operates the operation unit for a first activation time after the pump is activated by the switch. Regardless of the adjustment amount, the cooling water supply power of the pump is set to be larger than that of the medium.

  Further, the cooling device for a cooling garment of the present invention includes a water supply hose provided with a cooling water supply part and a cooling water branch part, and supplies cooling water from the cooling water supply part of the water supply hose to the cooling water branch part side. A pump to be connected to the cooling water branch of the water supply hose, at least one of a plurality of water distribution hoses connected to one end of the water supply unit, a control unit connected to the pump, and a control unit connected to the control unit, A switch for activating the pump, an operation unit connected to the control unit for adjusting the supply of cooling water by the pump, and a battery for supplying power to the pump; and The diameter is smaller than the diameter of the water supply hose, and the outer peripheral portion orthogonal to the longitudinal direction of each of the water supply hoses has an opening area smaller than the opening area of the one end side water supply portion of the water supply hose. Multiple small water holes The control unit adjusts the supply of cooling water by the pump for a first start-up time after the start-up of the pump by the switch, and adjusts the operation unit after the first start-up time has elapsed. The configuration is such that the supply of cooling water by the pump is set to be larger than the supply power set according to the amount.

  5. The cooling device for cooling clothes according to claim 4, wherein in the cooling device for cooling clothes of the present invention, the control unit is configured to adjust a driving time of a pump per unit time according to an adjustment amount of the operation unit. 6.

  In the cooling device for cooling clothing of the present invention, the control unit is connected to a voltage detection unit that detects a voltage of the battery, and the control unit detects that the voltage detected by the voltage detection unit is lower than the immediately preceding detection voltage. The cooling device for a cooling garment according to claim 5, wherein the pump is driven for a time longer than a value set by the operation unit when the temperature is lowered.

  The cooling garment of the present invention is provided with the cooling garment cooling device described above, and is arranged so that the water distribution hose is meandering.

  According to the present invention described above, the pump only needs to send cooling water from the cooling water supply section of the water supply hose to the cooling water branch section, so that power consumption can be reduced.

  Further, in the present invention, regardless of the adjustment amount of the operation unit, the supply of the cooling water by the pump is set to be larger than that during the first predetermined time after the pump is started by the switch for the first predetermined time. For example, even when there is a lot of air in the water distribution hose, the water pressure smoothly expels the air from the water distribution hose, and from the beginning of operation, the cooling water flows from the water holes in the wide part of the water distribution hose. Can be sufficiently discharged to enhance the cooling effect.

(Embodiment 1)
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a front view of a cooling garment equipped with the cooling garment cooling device according to the embodiment, and FIG. 2 is a rear view of the cooling garment.

In FIGS. 1 and 2, reference numeral 1 denotes a cooling garment, which comprises a front side garment 2, a back side garment 3, and left and right sleeves 4.
A water supply hose 7 provided with a cooling water supply unit 5 and a cooling water branching unit 6 is mounted in a vertical direction on a side portion of the clothing fabric 3 on the back side.

More specifically, the cooling water supply unit 5 extends to a lower portion of the cooling garment 1 and then extends out of the cooling garment 1, and a connector 8 is attached to the extension.
The cooling water branch 6 is provided at the other end of the water supply hose 7. In the present embodiment, the cooling water branch 6 branches at the other end of the water supply hose 7, and the left and right of the clothing 2 on the front side of the cooling garment 1. Cooling water branch portions 6 are arranged at a total of four places on the upper side and on the left and right upper sides of the clothes 3 on the back side of the cooling garment 1.
The connecting tool 8 connected to the cooling water supply unit 5 of the water supply hose 7 is connected to a pump 10 and a water supply pipe 11 via a connecting tool 9, and the water supply pipe 11 is inserted into, for example, a commercially available drinking water bottle 12. In this state, if the cap portion 13 is screwed into the drinking water bottle 12 by screwing, the water supply pipe 11 and the pump 10 are fixed to the drinking water bottle 12.
The pump 10 is provided with a control circuit unit 14, an operation unit 15, and a battery 16 shown in FIG. 9, so that the operation of the operation unit 15 allows the pump 10 to start, control the starting amount, and stop. I have.
That is, the cooling water can be supplied from the cooling water supply part 5 of the water supply hose 7 to the cooling water branch part 6 by the pump 10.

Returning to FIG. 1 and FIG. 2 again, a plurality of water distribution hoses 17 are connected to the four cooling water branch portions 6 of the water supply hose 7.
This point will be described in more detail. One end side water supply section 17a and the other end side water supply section 17b of a plurality of water distribution hoses 17 are connected to the four cooling water branch sections 6 of the water supply hose 7, respectively. I have.
In other words, since the diameter of the water distribution hose 17 is smaller than the diameter of the water supply hose 7, the cooling water branch portions 6 at the four locations of the water supply hose 7 are respectively provided with one end side water supply portions of the plurality of water distribution hoses 17. 17a and the other end side water supply part 17b can be connected.

The water distribution hose 17 is formed by a hollow fiber membrane. As shown in FIGS. 3 and 4, the water supply hose 17 is provided with water on one end side of the water distribution hose 17 at an outer peripheral portion orthogonal to the longitudinal direction. A plurality of water passage holes 17c having an opening area smaller than the opening areas of the portion 17a and the other end side water supply portion 17b are formed.
That is, as described above, the one end water supply section 17a and the other end water supply section 17b of the water distribution hose 17 are connected to the cooling water branch section 6 of the water supply hose 7, and the one end water supply section 17a and the other end water supply section are connected. The cooling water supplied from 17b flows out of the water distribution hose 17 from the water passage hole 17c.
That is, between the one end side water supply portion 17a and the other end side water supply portion 17b of the water distribution hose 17 formed by the hollow fiber membrane is a water discharge portion 17d of the water distribution hose 17, and the water discharge portion 17d is located on the front side. Is arranged in a meandering manner on the clothing 2 and the clothing 3 on the rear side, so that cooling water can be supplied to the entire surface of the cooling clothing 1.

The water distribution hose 17 will be further described. The water distribution hose 17 has a hollow fiber membrane having an outer diameter of 0.5 mm, and has an outer diameter of 0.4 μm or less on its outer peripheral surface. Are provided with countless water holes 17c.
More specifically, as shown in FIG. 3, each water passage hole 17c provided in the outer peripheral portion of the water distribution hose 17 is different from another water passage hole 17c adjacent thereto in the outer peripheral direction of the water distribution hose 17. Although independent, at least partly overlaps in the longitudinal direction of the same water hose 17. That is, in the hollow fiber membrane, countless water holes 17c are formed.
In this embodiment, as described above, in this embodiment, the outer peripheral portion orthogonal to the longitudinal direction of the water distribution hose 17 is provided with the opening area of the one end side water supply portion 17a and the other end side water supply portion 17b of the water distribution hose 17 as described above. This also expresses that a plurality of water passage holes 17c having a small opening area are formed.
As described above, one of the features of the present embodiment is that a hollow fiber membrane generally used for a liquid filter or the like is used as the water distribution hose 17.

  In the present embodiment, the cooling water supply unit 5 of the water supply hose 7 is disposed below the cooling garment 1 and the cooling water branch unit 6 is disposed above the cooling water branch unit 6. Since the water supply unit 17a and the other end water supply unit 17b are connected, the water discharge unit 17d is arranged in a meandering state on the cooling garment 1 below the one end water supply unit 17a and the other end water supply unit 17b. .

Next, the pump 10 will be described.
When the forward rotation switch 18 of the operation unit 15 is closed, the pump 10 is normally rotated by the control unit 19 via the switching elements 21 and 22, and conversely, the reverse rotation switch 23 of the operation unit 15 is closed. For example, the pump 12 is reversed by the control unit 19 via the switching elements 24 and 25.
Further, the strength of the normal rotation and the reverse rotation is adjusted by the volume 26 of the operation unit 15.
In other words, by adjusting the volume 26, the amount of electricity supplied to the pump 10 can be adjusted, so that the strength of forward rotation and reverse rotation can be adjusted accordingly.

The operation unit 15 will be described in more detail. In this embodiment, the operation unit 15 is configured by a volume 26, and the control unit 19 controls the water supply amount of the pump 10 to at least 1 (small), 2, 3 (medium), , 5 (large).
Specifically, when 5 (large) is set by the volume 26, the pump 10 is driven at a rotation of, for example, 5000 rpm for 20 seconds per minute.
When 4 is set by the volume 26, the pump 10 is driven at a rotation of, for example, 5000 rpm for 18 seconds per minute.
When 3 (medium) is set by the volume 26, the pump 10 is driven at a rotation of, for example, 5000 rpm for 15 seconds per minute.
When 2 is set by the volume 26, the pump 10 is driven at, for example, 5000 rpm for 13 seconds per minute.
When 1 (small) is set by the volume 26, the pump 10 is driven at a rotation of, for example, 5000 rpm for 10 seconds per minute.
In the present embodiment, even when the pump 10 is intermittently driven as described above, the cooling water is sufficiently leaked out from the water passage hole 17c of the water distribution hose 17, so that the power consumption of the pump 10 is reduced. can do.

Next, a main part of the method of manufacturing the cooling garment 1 of the present embodiment will be described.
FIG. 10 shows a state in which the clothing 2 on the front side and the clothing 3 on the back side of the cooling garment 1 are cut.

  First, the water-dividing hose 17 in the wound state is sewn to the upper left (point A) of the clothing 2 on the front side, and the water-dividing hose 17 is not sewn to the area C. Next, after passing through the area C, the winding thread is sewn simultaneously while meandering downward, and then simultaneously sewn while being meandering upward from below (the sewing thread 27 is shown in FIG. 5). This is repeated to complete the left side zone of the front side fabric 2 in FIG. 11 and then to the right side zone of the front side fabric 2 in FIG.

Thereafter, the clothing is continuously shifted to the right side zone of the back side fabric 3 and then to the left side zone of the back side fabric 3 to reach the point B, and the water distribution hose 17 is arranged.
That is, since the water distribution hose 17 is arranged in one stroke from the point A to the point B, the mounting operation can be performed efficiently.

Then, as shown in FIG. 12, if the front side fabric 2 and the back side fabric 3 are separated at the connecting portion, the water supply hoses 17 on the left and right sides of the front side fabric 2 are supplied with water on one end side. The part 17a and the other end side water supply part 17b are present.
In addition, one end side water supply portion 17a and the other end side water supply portion 17b of the plurality of water distribution hoses 17 are also present on the left and right upper portions of the back side fabric 3.
In addition, one end side water supply section 17a and the other end side water supply section 17b of each water dividing hose 17 are not thread-fixed to the front side fabric 2 and the back side fabric 3, and can be freely moved. It is in a state.

In this state, as shown in FIG. 5 and FIG. 6, the one end side water supply portion 17a and the other end side water supply portion 17b of the water distribution hose 17 are inserted into the connection tool 28, and then, as shown in FIG. As shown, the adhesive 30 is injected from the opening 29 of the connector 28.
That is, one end side water supply portion 17a and the other end side water supply portion 17b of the plurality of water distribution hoses 17 are fixed to the front side fabric 2 and the back side fabric 3 together with the connector 28 by the adhesive 30. .

At this time, in order to prevent the one end side water supply portion 17a and the other end side water supply portion 17b of the plurality of water distribution hoses 17 from being clogged with the adhesive 30, the one end side water supply portion 17a of the water distribution hose 17 is not required. The other end side water supply portion 17b is sufficiently drawn out of the connecting member 28 (upward in FIG. 5 or right side in FIG. 8), and cuts off the portion of the adhesive 30 that has protruded from the connecting portion 20 after curing.
Further, the water distribution hose 17 is formed of a hollow fiber membrane as described above, and the water passage hole 17c on the outer peripheral surface thereof has an extremely small opening area. There is no intrusion into the hose 17 and no clogging occurs in this portion.

  Finally, in FIG. 5, the cooling water branch portion 6 of the water supply hose 7 is pushed into the outer periphery of the connection portion 20 of the connecting member 28 while being elastically deformed, and the water distribution hose 17 is inserted into the cooling water branch portion 6 of the water supply hose 7. One end side water supply section 17a and the other end side water supply section 17b are connected.

The operation of the above configuration will be described.
First, the user wears the cooling garment 1 of FIG.
Next, the water supply pipe 11 is inserted into, for example, a commercially available drinking water bottle 12, and in this state, the cap 13 is screwed into the drinking water bottle 12 to screw the water supply pipe 11 and the pump 10. It is fixed to the bottle 12 (the drinking water bottle 12 is filled with sterilized tap water).
Then, when the switch 18 for normal rotation of the operation unit 15 is closed, the pump 10 is normally rotated via the switching elements 21 and 22 by the control unit 19, whereby the cooling water in the drinking water bottle 12 is supplied to the water supply hose 7. Through the cooling water supply unit 5, the cooling water branching unit 6, and the water supply hose 17 at one end side water supply unit 17a and the other end side water supply unit 17b. From the innumerable water holes 17c formed into the clothing 2 on the front side and the clothing 3 on the back side of the cooling garment 1 and are vaporized by outside air, wind and the like.

  In other words, even if the user is not sweating, effective cooling can be performed by the heat of vaporization of the cooling water in the cooling garment 1.

  As described above, according to the present embodiment, since the pump 10 only needs to send the cooling water from the cooling water supply unit 5 of the water supply hose 7 to the cooling water branch unit 6, it is possible to reduce the power consumption. it can.

The cooling water sent to the cooling water branch 6 of the water supply hose 7 is distributed from one end water supply 17a and the other end water supply 17b of the plurality of water distribution hoses 17 connected to the cooling water branch 6. The water flows into the water hose 17, and then flows out from the plurality of water holes 17 c existing in the water outlet 17 d of each water dividing hose 17.
At this time, since the water outlet 17d meanders the cooling garment 1 widely, an appropriate amount of cooling water can be supplied to a wide area of the body, and as a result, the cooling effect is high.
That is, in the present embodiment, if the cooling water is sent from the cooling water supply unit 5 of the water supply hose 7 to the cooling water branch unit 6 by the pump 10, the water is then passed through the water separation hose 17 that is open to the atmosphere. The gravity of the cooling water itself from the water hole 17c and the capillary phenomenon formed by the small water passage hole 17c also act and flow out of the water distribution hose 17, so that the power consumption of the pump 10 can be suppressed. You can.
As an example, in the present embodiment, even if a 3V battery 16 in which two AA batteries are connected in series is used, it can be used for 8 hours or more.

  Further, the diameter of each water dividing hose 17 is smaller than the diameter of the water supply hose 7, and the water dividing hose 17 has an outer peripheral portion perpendicular to the longitudinal direction, and one end side water supply portion of the water dividing hose 17. Since a plurality of water passage holes 17c having a smaller opening area than the opening areas of the water supply portion 17a and the other end side water supply portion 17b are formed, the cooling water flowing out of the water distribution hose 17 has a wide range. In addition, since it is in a small amount and oozes out in a small amount, there is no large wet feeling in a part of the body and comfortable cooling can be performed.

In addition, although it depends on a use environment, in this embodiment, since 500 cc of cooling water is used in one hour, a commercially available drinking water container is used as the drinking water bottle 12 in the cap portion 13 as it is. I try to combine.
Then, if the cooling water runs out, the drinking water bottle 12 can be used continuously simply by adding tap water again.

  In addition, the switch 23 for reverse rotation causes the pump 10 to reverse when the previous cooling water remains in the water distribution hose 17 and also in a state where air is present, that is, in a so-called air entrapment state. It is provided to eliminate the air trapped in the hose 17.

In addition, such a cooling garment 1 is often used in an outdoor high temperature environment. For example, even if a part of the water distribution hose 17 is clogged with dust or the like, in the present embodiment, the cooling garment 1 is continuously used. The cooling operation can be continued.
That is, in the present embodiment, one end water supply section 17a and the other end water supply section 17b of each water supply hose 17 are connected to the cooling water branch section 6 of the water supply hose 7, so that Cooling water is supplied from both the one end water supply section 17a and the other end water supply section 17b to the water discharge section 17d. As a result, even if a part of the water distribution hose 17 is clogged, Cooling water is supplied from the one end water supply portion 17a to the one end water supply portion 17a side of the clogged portion, and from the other end water supply portion 17b side to the other end water supply portion 17b side of the clogged portion. As a result, a long-term stable cooling effect can be exhibited.

Next, the features of this embodiment will be described.
As described above, in the present embodiment, when the switch 18 for normal rotation of the operation unit 15 is closed, the pump 10 is normally rotated by the control unit 19 via the switching elements 21 and 22, and thereby, the inside of the drinking water bottle 12 is The cooling water is arranged in a meandering state on the cooling garment 1 via the cooling water supply section 5, the cooling water branch section 6, and the water supply hose 17 at one end water supply section 17a and the other end water supply section 17b of the water supply hose 7. From the countless water holes 17c formed in the water outlet 17d of the water distribution hose 17, the clothes 2 on the front side and the clothes 3 on the back side of the cooling garment 1 flow out, and the outside air and the wind It is vaporized by.

This state will be described in more detail. When the forward rotation switch 18 of the operation unit 15 is closed, the pump 10 is normally rotated by the control unit 19 via the switching elements 21 and 22. In this state, in this embodiment, The control unit 19 performs the operation of FIG.
First, the control unit 15 determines whether the forward rotation switch 18 is in the ON state (S1 in FIG. 13).
When the forward rotation switch 18 is in the ON state, the supply power of the cooling water by the pump 10 during the first startup time (for example, 20 seconds) regardless of the adjustment amount of the volume 26 of the operation unit 15. Is set to be larger than the middle (S2, S3 in FIG. 13).
That is, in the present embodiment, as described above, the operation unit 15 is configured by the volume 26, and the control unit 19 controls the water supply amount of the pump 10 to at least 1 (small), 2, 3 (medium), 4, 5 ( Large) can be adjusted in five stages.

Specifically, when 5 (large) is set by the volume 26, the pump 10 is driven at a rotation of, for example, 5000 rpm for 20 seconds per minute.
When 4 is set by the volume 26, the pump 10 is driven at a rotation of, for example, 5000 rpm for 18 seconds per minute.
When 3 (medium) is set by the volume 26, the pump 10 is driven at a rotation of, for example, 5000 rpm for 15 seconds per minute.
When 2 is set by the volume 26, the pump 10 is driven at, for example, 5000 rpm for 13 seconds per minute.
When 1 (small) is set by the volume 26, the pump 10 is driven at a rotation of, for example, 5000 rpm for 10 seconds per minute.

However, in the present embodiment, during the period of 20 seconds (first activation time) from when the forward rotation switch 18 is turned on, regardless of the adjustment amount of the volume 26 of the operation unit 15, the cooling water by the pump 10 is controlled. The supply force is set to 4 or larger (5) than the medium (3).
For example, even if the adjustment amount of the volume 26 of the operation unit 15 is 1 (small), the supply of cooling water by the pump 10 is the amount of water supply when the adjustment amount of the volume 26 is 4 or 5 (large). . Similarly, even if the adjustment amount of the volume 26 of the operation unit 15 is 2, the supply power of the cooling water by the pump 10 becomes the water supply amount when the adjustment amount of the volume 26 is 4 or 5 (large), and Even if the adjustment amount of the volume 26 of the 15 is 3, the supply power of the cooling water by the pump 10 is the water supply amount when the adjustment amount of the volume 26 is 4 or 5 (large). Further, if the adjustment amount of the volume 26 of the operation unit 15 is 4, the supply power of the cooling water by the pump 10 becomes the water supply amount when the adjustment amount of the volume 26 is 4 or 5 (large). If the adjustment amount of the volume 26 is 5 (large), the cooling water supply power by the pump 10 is the water supply amount when the adjustment amount of the volume 26 is 4 or 5 (large).

  For this reason, for example, even when a large amount of air is present in the water distribution hose 17, the air is smoothly expelled from the water distribution hose 17 by the water pressure, so that a wide portion of the water distribution hose 17 can be passed from the beginning of operation. The cooling water is allowed to sufficiently flow out from the water holes 17c, so that the cooling effect can be enhanced.

Then, after the elapse of 20 seconds (first activation time), the control unit 19 detects the voltage of the battery 16 (S4 in FIG. 13).
For example, in the present embodiment, since the battery 16 is set to 3 V, it detects how many volts the voltage is currently.
Note that the voltage detection of the battery 16 is measured by the resistance voltage dividing unit 31 shown in FIG.

Next, it is detected which value the output is set by the volume 26 (S5 in FIG. 13).
That is, if the voltage of the battery 16 drops below the detected voltage measured immediately before, the rotation speed of the pump 10 drops. Therefore, if the voltage drops, the preset value of the volume 26 at that time is used. The driving time of the pump 10 is adjusted so as to be larger than the output (rotation speed) of the pump 10 (S6 in FIG. 13).
For example, if the setting value of the volume 26 is 3 (medium), the pump 10 is driven to rotate for 15 seconds per minute. However, if the voltage of the battery 16 decreases, the pump 10 By rotating and driving for 20 seconds per minute, it is trying to suppress a decrease in the cooling effect. If the time is longer than the set value of the volume 26, it may be, for example, 16 seconds or more, or 20 seconds or more.

  The operation while detecting the voltage state of the battery 16 is continued until the forward rotation switch 18 is turned off, and the operation ends when the forward rotation switch 18 is turned off (S7 and S8 in FIG. 13). .

Next, when the reverse switch 23 is turned on, the same operation is performed.
In other words, when the previous cooling water remains in the water distribution hose 17 and air also exists, so that a so-called air entrapment state occurs, the pump 10 is reversed and the air entrapment state in the water diversion hose 17 is changed. In order to solve the problem, a switch 23 for reverse rotation is prepared.
When the switch 23 for reverse rotation is turned on (S9 in FIG. 13), the control unit 19 detects the voltage of the battery 16 (S10 in FIG. 13).
For example, in the present embodiment, since the battery 16 is set to 3 V, it detects how many volts the voltage is currently.
Although not shown in FIG. 9, the voltage of the battery 16 can be easily measured by connecting a divided resistor in parallel to the battery 16 and connecting the midpoint thereof to the control unit 19.

Next, it is detected which value the output is set by the volume 26 (S11 in FIG. 13).
That is, if the voltage of the battery 16 drops below the detected voltage measured immediately before, the rotation speed of the pump 10 drops. Therefore, if the voltage drops, the preset value of the volume 26 at that time is used. The drive time of the pump 10 is adjusted so as to be larger than the output (rotation speed) of the pump 10 (S12 in FIG. 13).
For example, when the setting value of the volume 26 is 3 (medium), the pump 10 is driven to rotate for 15 seconds per minute. However, when the voltage of the battery 16 decreases, the pump 10 By rotating for 20 seconds per minute, it is intended to suppress a decrease in the air discharging effect. If the time is longer than the set value of the volume 26, it may be, for example, 16 seconds or more, or 20 seconds or more.
When 20 seconds have elapsed, the operation ends (S13 and S8 in FIG. 13).

Another role of the reverse rotation drive of the pump 10 is to discharge water remaining in the tube after use, so that an effect of hastening drying can be expected.
In addition, by turning on the switch 23 for reverse rotation, when drinking water is required in the case of disaster or distress, a minimum amount of drinking water can be prepared.
That is, when the cooling garment 1 is immersed in, for example, a river and the switch 23 for reversing is turned on, the water of the river flows from the water-passing hole 17c of the water-dividing hose 17 made of a hollow fiber membrane into the water-dividing hose 17. Then, the water can be collected in the drinking water bottle 12 via the water distribution hose 17 and the water supply hose 7. Since the water passage hole 17c of the water distribution hose 17 made of a hollow fiber membrane is 0.2 to 0.4 μm, emergency drinking water from which bacteria and Escherichia coli have been removed can be secured.

In the above-described embodiment, the first start-up time from when the forward rotation switch 18 is turned on is, for example, 20 seconds. However, the first start-up time may be shorter or longer than 20 seconds. As long as the air in the water distribution hose 17 can be driven out of the water distribution hose 17 by water pressure, the time may be shorter or longer than 20 seconds.
That is, it is important that the cooling water is sufficiently discharged from the water passage hole 17c of the wide part of the water distribution hose 17 from the initial operation to enhance the cooling effect.

(Embodiment 2)
Next, another embodiment of the present invention will be described.
That is, in the above-described embodiment, when the forward rotation switch 18 is in the ON state, regardless of the adjustment amount of the volume 26 of the operation unit 15, the pump is not activated during the first activation time (for example, 20 seconds). Although the configuration is such that the supply power of the cooling water by 10 is made larger than that in the middle, this point is changed.

Specifically, after the pump 10 is started, for a first start time (for example, 20 seconds), the supply power of the cooling water by the pump 10 is reduced by the operation unit 15 after the elapse of the first start time. The cooling water supply power by the pump 10 set according to the adjustment amount of the volume 26 is set to be larger.
For example, after the pump 10 is started, during the first start-up time (for example, 20 seconds), even if the adjustment amount of the volume 26 of the operation unit 15 is 1 (small), the supply of cooling water by the pump 10 Is the water supply amount when the adjustment amount of the volume 26 is 2 or more.
Similarly, even if the adjustment amount of the volume 26 of the operation unit 15 is 2, the cooling water supply power by the pump 10 is set to the water supply amount when the adjustment amount of the volume 26 is 3 (medium) or more.
Even when the adjustment amount of the volume 26 of the operation unit 15 is 3 (medium), the supply power of the cooling water by the pump 10 is set to the water supply amount when the adjustment amount of the volume 26 is 4 or more.
Further, even when the adjustment amount of the volume 26 of the operation unit 15 is 4, the supply power of the cooling water by the pump 10 is set to the water supply amount when the adjustment amount of the volume 26 is 5 (large).
Even when the adjustment amount of the volume 26 of the operation unit 15 is 5 (large), the supply power of the cooling water by the pump 10 is made larger than the water supply amount when the adjustment amount of the volume 26 is 5 (large). . When the adjustment amount of the volume 26 of the operation unit 15 is 5 (large), the pump 10 is driven at a rotation of, for example, 5000 rpm for 30 seconds per minute.

  For this reason, for example, even when a large amount of air is present in the water distribution hose 17, air is smoothly expelled from the water distribution hose 17 by the water pressure, so that a wide portion of the water distribution hose 17 can be passed from the beginning of operation. The cooling water can be sufficiently discharged from the water holes 17c, and the cooling effect can be enhanced.

  Note that the other configuration is the same as the above (Embodiment 1), and thus is omitted to avoid complication of description.

  As described above, the embodiments of the present invention have been described in detail, but the present invention is not limited to the above embodiments. The present invention is capable of various design changes without departing from the scope of the claims. INDUSTRIAL APPLICABILITY The present invention is an effective cooling garment for outdoor activities and outdoor duties in the high-temperature season, or indoor duties in a high-temperature environment.
