Description

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

  There has been proposed a cooling garment that can cool the body without presuming the sweat of the wearer. Specifically, a water storage tank is mounted on the shoulder, and one end of the water supply hose is connected to the water storage tank. Next, the middle part of the water supply hose is meandered by the body part, and then the other end of the water supply hose. Is connected to the water storage tank. Further, 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, Patent Document 1 shown below exists as a prior document similar to this).

  With the above configuration, the water supply hose has water passage holes formed at predetermined intervals from one end side to the other end side. Accordingly, in the state where the pump is driven and the cooling water in the water storage tank is circulated to one end, the middle part, the other end of the water supply hose and the water storage tank, a part of the cooling water flows out from the water passage hole. When the clothes are wet and the wind from the blower fan passes through the clothes, the heat of vaporization is taken away, and as a result, the body can be cooled. In other words, since the cooling water flowing out from the water hole of the water supply hose is vaporized and the body can be cooled with this heat of vaporization, the body can be cooled without assuming the sweating of the wearer. It has become.

  However, in such a conventional configuration, a circulation path (water storage tank, one end of the water supply hose, the middle part, the other end, the water storage tank) is formed in the water storage tank by a water supply hose connecting one end side and the other end side thereof. Therefore, the load as a pump is large and the power consumption is large.

  In addition, when the opening area of the water passage hole of the water supply hose is increased, a large amount of cooling water in the water storage tank flows out from the water passage hole of the water supply hose, and as a result, the cooling operation cannot be performed for a long time. Therefore, the opening area of the water passage hole is reduced, but in order to allow a part of the circulating water to flow out from the small water passage hole, the pressure of the pump must be increased. Therefore, the power consumption of the pump becomes a problem.

  Moreover, if the pressure of the pump is high and the opening area of the water passage hole is small, the cooling water will jump out of the water passage hose vigorously, making it impossible to perform a preferable cooling operation.

  Therefore, the present invention aims to suppress the power consumption of the pump.

And in order to achieve this object, the cooling device for cooling clothes of the present invention comprises a cooling water supply part, a water supply hose provided with a cooling water branch part, and a cooling water branch part from the cooling water supply part of the water supply hose.

(Embodiment 1)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  On the surface side of the cooling garment 3 according to the present invention, as shown in FIGS. 2 and 3, a plurality of water diversion hoses 8 are arranged in a meandering state. Further, a water supply hose 9 is disposed on the surface side of the side portion of the cooling garment 3 as shown in FIG.

  This water supply hose 9 is made of synthetic resin or rubber, and a pump 12 is connected to a cooling water supply unit 10 set at one end opening (below the cooling garment 3) via a joint 11. Further, a suction port 14 penetrating the lid 13 is connected to the pump 12. That is, the suction port 14 is inserted into the water supply container 15, and the lid 13 is detachably attached to the opening 16 of the water supply container 15 in this state.

  As shown in FIG. 3, the other end of the water supply hose 9 is pulled up upward on the surface side of the cooling garment 3, and then branched to the left and right via a left and right branching portion 17. Each end opening is a cooling water branch 18.

  A tubular coupler 19 shown in FIG. 7 is inserted into and coupled to the cooling water branching portion 18. The tubular coupler 19 is previously connected to the plurality of parts as shown in FIG. The upper end opening of the water hose 8 is inserted and bonded and fixed in an assembled state. Next, as shown in FIG. 7, the upper end opening of the diversion hose 8 is at the inner end of the water supply hose 9 of the tubular coupler 19. It is in a disconnected state. As a result, the upper end openings of the plurality of water diversion hoses 8 are each opened in the cooling water branching portion 18 of the water supply hose 9, and the cooling water from the cooling water branching portion 18 of the water supply hose 9 is divided into the plurality of water diversions. It flows from the upper end opening of the hose 8.

  As understood from these explanations, the diameter of the water diversion hose 8 is smaller than the diameter of the water supply hose 9, and the water diversion hose 8 has an outer peripheral portion perpendicular to the longitudinal direction thereof, as shown in FIGS. As shown in FIG. 6, a plurality of water passage holes 20 having an opening area smaller than the opening area of the upper end opening (one end opening) of the diversion hose 8 are formed. Specifically, the water diversion hose 8 is a hollow fiber membrane having an outer diameter of 0.5 mm, and the outer peripheral surface has innumerable water passage holes 20 having an opening diameter of 0.4 μm or less. Is provided.

  More specifically, each water hole 20 provided in the outer peripheral portion of the water diversion hose 8 is formed adjacent to the outer circumferential direction intersecting the longitudinal direction of the water diversion hose 8 as shown in FIG. Yes. Therefore, a plurality of water passage holes 20 exist in any cross section of the water diversion hose 8.

  Thus, one of the features of the present embodiment is that a hollow fiber membrane that is generally used for a liquid filter or the like is utilized as the diversion hose 8. As described above, the cooling device for cooling clothes is configured. The cooling device for the cooling garment is attached to the cooling garment 3 or attached to an existing garment. Since the diversion hoses 8 are in an unrestrained state, the diversion hoses 8 can be dispersed and arranged at arbitrary positions according to clothes.

  Since such a thin hollow fiber membrane is used as the diversion hose 8 and the other end of each diversion hose 8 is in an unconstrained state so as to be distributed and arranged for each diversion hose 8, as shown in FIGS. As shown in FIGS. 2 and 3, the water diversion hoses 8 can be arranged in a meandering state on the front and back surfaces of the cooling garment 3 while being separated by a predetermined distance. And if it is such a thin water diversion hose 8, as shown in FIG. 2, FIG. 3, in the state which isolate | separated each water diversion hose 8 in the meandering state and arrange | positioned as shown in FIG. 3 can be easily fixed with the sewing thread 21. By meandering, the hollow fiber membrane can follow the expansion and contraction even when a stretchable fabric is used.

  The other end opening (lower end opening) of each diversion hose 8 may be left open as shown in FIG. 9, but when the amount of cooling water flowing out from this opening is large, The mouth may be closed by bending as shown in FIG. 10 or applying an adhesive (not shown) to the opening.

  As described above, in the present embodiment, the cooling water supply unit 10 is provided at one end opening of the water supply hose 9 and is disposed below the cooling garment 3, and then provided on the other end side of the water supply hose 9. The cooling water branch portion 18 is disposed above the cooling garment 3. Further, the cooling water branching portion 18 is disposed in the vicinity of the left and right shoulders above the cooling garment 3, and the tubular coupler 19 is inserted and fixed therein, thereby connecting the plurality of water diversion hoses 8.

  The pump 12 is connected to a control circuit as shown in FIG. That is, if the forward rotation switch 22 (an example of the operation unit) is closed, the pump 12 is normally rotated by the control unit 23 via the switching elements 24 and 25, and conversely, the reverse rotation switch 26 (an example of the operation unit). Is closed, the control unit 23 reverses the pump 12 through the switching elements 27 and 28. Further, the strength of normal rotation and reverse rotation is adjusted by a volume 29 (an example of an operation unit).

  That is, if the volume 29 is adjusted, the energization amount to the pump 12 can be adjusted as shown in FIGS. 12 (a), 12 (b), and 12 (c), and the strength of forward rotation and reverse rotation is adjusted accordingly. I can do it.

  The strengths of forward rotation and reverse rotation are in the order of FIGS. 12C, 12B, and 12A, and FIG. 12C can make forward rotation and reverse rotation the strongest.

  Further, in this embodiment, even when the pump 12 is intermittently driven, the cooling water sufficiently oozes out from the water passage hole 20 of the diversion hose 8, so that the power consumption of the pump 12 can be reduced.

  Further, the material of the cooling garment 3 is preferably one that closely contacts the body, and an elastic knit fabric is suitable.

  The operation will be described in the above configuration.

  First, the user inserts the suction port 14 penetrating the lid 13 into the water supply container 15, and in this state, attaches the lid 13 to the opening 16 of the water supply container 15 and closes the lid. In this state, the forward switch 22 is closed, and the control unit 23 causes the pump 12 to rotate forward via the switching elements 24 and 25. Then, the cooling water in the water supply container 15 is pumped by the pump 12, the cooling water supply unit 10 at one end opening of the water supply hose 9, then the cooling water branching unit 18 provided on the other end side of the water supply hose 9, It will flow into the plurality of water diversion hoses 8.

  At this time, the cooling water branching portion 18 is disposed in the vicinity of the left and right shoulders above the cooling garment 3, and the tubular coupler 19 is inserted and fixed therein, thereby connecting the upper ends of the plurality of water diversion hoses 8; The lower end of the water diversion hose 8 is arranged below the cooling garment 3.

  For this reason, while cooling water flows downward of the diversion hose 8, the cooling water oozes out from the water passage hole 20 on the way, and the oozing cooling water soaks into the cooling garment 3. For this reason, although it is not sweating, a user's body can be cooled effectively because heat of vaporization is taken away by the cooling clothes 3.

  As described above, according to the present embodiment, the pump 12 only needs to send the cooling water from the cooling water supply unit 11 to the cooling water branching unit 18 of the water supply hose 9, thereby reducing power consumption. it can.

  Further, the cooling water sent to the cooling water branching portion 18 of the water supply hose 9 flows into the plurality of water diversion hoses 8 connected to the cooling water branching portion 18, and then the plurality of water diving hoses 8. Although it will flow out from the water flow hole 20, since the other end side of each diversion hose 8 is made into the unconstrained state so that dispersion | distribution arrangement | positioning is possible for every diversion hose 8, the diversion hose 8 is disperse | distributed. If arranged, an appropriate amount of cooling water can be supplied to a wide area of the body, resulting in a high cooling effect.

  That is, in this embodiment, if the cooling water is sent from the cooling water supply part 11 of the water supply hose 9 to the cooling water branching part 18 by the pump 12, then the water supply hose 8 that is released to the atmosphere is passed through. The gravity of the cooling water itself from the water holes 20 and the capillary phenomenon formed by the small water flow holes 20 also act and flow out of the diversion hose 8, thereby suppressing the power consumption as the pump 12. It can be done. As an example, in the present embodiment, even when using a 3V power source in which two AA batteries are connected in series, use for 8 hours or more is possible.

  Furthermore, the diameter of each water diversion hose 8 is made smaller than the diameter of the water supply hose 9, and the water diversion hose 8 has an outer peripheral portion orthogonal to the longitudinal direction thereof and an opening of one end of the water diversion hose 8. Since the plurality of water passage holes 20 having an opening area smaller than the opening area are formed, the cooling water flowing out from the diversion hose 8 is a small amount and a small amount of cooling water. Since it oozes out, there is no feeling of water dripping on a part of the body, and comfortable cooling can be performed.

  Although the amount of cooling water flowing out from the diversion hose 8 is in a state where a small amount oozes out from the small water passage hole 20, the cooling water branching portion 18 side still flows out more than the lower end opening portion side. Therefore, when the shoulder portion of the cooling garment 3 is wet and sticky, water is divided by painting or adhesive with 1/3 to 2/3 of the total length of each water diversion hose 8 as an open area suppression region. The portion close to the portion 17 is, for example, plugging 90% of the opening and changing the area to be closed in a gradation from 90% to 0% as it goes to the tip to change the amount of cooling water flowing out. Can do.

  Further, as shown in FIG. 7, in the adhesive fixing region 30 on the cooling water branching portion 18 side of the diversion hose 8, the diversion hose 8 uses a thin hollow fiber membrane as described above, so that the strength is weak. Moreover, since it is difficult to adopt a stress-reducing configuration by meandering in the vicinity of the joint with the cooling water branching portion 18, the strength of this portion may become a problem. By fixing to the garment 3, the strength of this part is also increased.

  Although depending on the use environment, in this embodiment, since 500 cc of cooling water is used in one hour, a commercially available drinking water container is directly connected to the lid 13 as the water supply container 15. I am doing so. And if this cooling water is lost, continuous use can also be easily performed by putting tap water into the water supply container 15.

  The reversing switch 26 reverses the pump 12 when the previous cooling water remains in the water diving hose 8 and air also exists, so that a so-called air clogging state is established. It is prepared to eliminate the air catch in the hose 8.

  In FIG. 1, a garment 2 with a blower includes a cooling garment 3 worn inside the garment 2 with a blower.

  The garment 2 with a blower is formed of a material that suppresses air permeability, and a blower fan 4 that takes in air outside the garment 2 with a blower into the garment 2 with a blower is mounted below the back side of the garment. Moreover, the fastening part 5 which suppresses the clearance gap with a body is formed under the clothes 2 with a fan. That is, if the blower fan 4 is driven, the air outside the blower-equipped garment 2 is taken into the blower-equipped garment 2 from the blower fan 4 portion, then rises along the surface of the cooling garment 3, and thereafter Then, it flows out from the collar neck opening 6 and the sleeve opening 7 of the garment 2 with a blower out of the garment 2 with a blower.

  It is already well known that such air outside the garment 2 with the blower is taken into the garment 2 with the blower by the blower fan 4 to cool the body, and the configuration of the cooling garment 3 has already been described in the first embodiment.

Next, the suction port 14 penetrating the lid 13 is inserted into the water supply container 15, and in this state, the lid 13 is attached to the opening 16 of the water supply container 15 and is covered. Thereafter, the blower fan 4 is driven.

  Then, the air outside the garment 2 with the blower is taken into the garment 2 with the blower from the portion of the blower fan 4, and then rises along the surface of the cooling garment 3. It flows out of the clothes 2 with a fan from the part 6 and the sleeve opening part 7. While the cooling water flows downward from the diversion hose 8, the cooling water oozes out from the water passage hole 20 on the way, and the exuding cooling water soaks into the cooling garment 3 and flows upward on the surface of the cooling garment 3. Vaporization is caused by blowing air from the blower fan 4.

That is, if the cooling garment 3 is attached to a thermal mannequin used for measuring the heat retention of clothes, it can be utilized as a sweating thermal mannequin that simulates sweating of a human body.

  In the above-described embodiment, the attachment to only the body portion has been described as an example, but the same principle can be applied to the limbs, the head, or the lower body. That is, it is possible to take a cooling measure that simulates sweating of the whole body.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims. The present invention provides a cooling garment that is effective in outdoor activities, outdoor work, or indoor work in a high temperature environment in the high temperature season.
