Description

Technical Field

[0001] The present invention relates to a body cooling means for adjusting body temperature by bringing a refrigerant pipe into contact with the body. More specifically, it relates to a body cooling means that can be easily attached to a widely popular baby stroller and can be reinstalled from an old baby stroller to a new one even when replacing the baby stroller.

[0002] In addition, the body cooling means of the present invention is configured to be usable even after the infancy period. More specifically, it relates to a body cooling means set that can be reused as cooling clothing by removing the heat exchange device from the baby stroller and carrying it like a backpack, and attaching the refrigerant pipe to meander along the inner surface of the outerwear.

Background Art

[0003] It is recommended to let infants take sunbaths from around 1 month after birth. The reason is that breast milk contains less vitamin D than cow's milk, and by promoting the production of vitamin D through sunbathing, it is expected to reduce the incidence of allergic diseases due to improved immunity and to promote the growth of infants. Furthermore, it is also said that sunbathing helps infants acquire a circadian rhythm and can be expected to reduce night crying. However, during outdoor walks in summer, there is a risk that infants may suffer from heat stroke, and there is a demand for a baby stroller that allows safe and comfortable outings.

[0004] By the way, mainly two types of baby strollers are popular: type A baby stroller 400 (carrycot) and type B baby stroller 500 (stroller) (see Fig. 7 and the standards of the General Incorporated Foundation Product Safety Association). The type A baby stroller 400 can be used with the seat part 401 in a substantially flat state by the reclining function, so it can be used from 1 month after birth before the baby can hold its head (see Fig. 7(A)). The type B baby stroller 500 cannot recline the seat part 501 to the horizontal position, and since it is necessary to seat the infant, it is intended for use after 7 months after birth when the baby can hold its head (see Fig. 7(B)).

[0005] Many families purchase Type A strollers to allow their babies to enjoy sunbathing and walks in parks from an early age. However, Type A strollers (400) are equipped with reclining mechanisms and other features, so most models weigh around 10 kg, which is about twice as heavy as Type B strollers (500), making them difficult to handle. As a result, despite Type A strollers costing twice as much on average as Type B strollers, many families are forced to dispose of or give away their Type A strollers around the first year of life and buy lighter, easier-to-carry Type B strollers, which becomes a financial burden on the household.

[0006] Due to these circumstances, high-performance strollers equipped with heatstroke prevention measures, which would further increase household expenses, have not become widespread. Therefore, the applicant has diligently researched a body cooling method that can be retrofitted to any widely available type of stroller and does not require the purchase of a new one when replacing the stroller, and has developed the present invention.

[0007] Patent Document 1 discloses technology for a mobile vehicle equipped with an air conditioning system. More specifically, it describes equipping strollers and wheelchairs rented out at amusement parks, etc., with an ammonia absorption chiller, and using a fan to blow cool air onto the occupants to cool their bodies.

[0008] However, even if an air conditioning system is installed in a stroller used outdoors, it would be necessary to cool the hot outside air each time the fan is turned on, and since most of the generated cool air is diffused back into the outside air, most of the electricity would not be used effectively. Therefore, a high-output and large air conditioning system would be required, which presented a challenge as it could not be used in the common strollers that are widely available. Furthermore, since the baby's back is in contact with the backrest, it is prone to sweating, and there was also the challenge of not being able to provide a comfortable environment for infants who are susceptible to heat rash.

[0009] Patent Document 2 discloses a technology for an infant seat that can be detachably attached to a stroller. According to the technology described in this document, outside air is drawn into the housing of a cooling device by a blower fan, and the drawn-in outside air is cooled by a Peltier element installed inside the housing. The cooled outside air is sent by the blower fan into a ventilation channel formed in the cushion seat on which the infant sits. The cold air flowing through the ventilation channel is released from pores formed on the surface side of the cushion seat, and is said to cool the body of the infant sitting there.

[0010] However, in this paper, high-temperature outside air is taken into the cooling device, cooled, and sent to a cushion sheet. The cooled outside air is then released back into the outside air from the cushion sheet. Therefore, unlike indoor air conditioning systems that cool enclosed spaces, it is necessary to constantly exchange heat with the hot outside air in summer, which resulted in poor cooling efficiency. Moreover, in recent years, there have been consecutive days with maximum temperatures exceeding 35°C, and the outside temperature is even higher on paved sidewalks, so there was a high possibility that the outside air could not be cooled sufficiently in the short time it was in contact with the Peltier element.

[0011] Furthermore, the cushion seat maintains its inflated shape using foam material to create ventilation channels and pores. However, this presented a challenge in usability, as the cushion seat could not be folded down to a small size even when the stroller was folded to avoid inconveniencing other passengers on public transportation. Additionally, when the cushion seat was soiled by vomit or other bodily fluids, while the surface cover could be washed, the foam material could not, posing a hygiene management challenge. Moreover, the large diameter air vent attached to the top of the seat's backrest could potentially interfere with the attachment of the sunshade. [Prior art documents] [Patent Documents]

[0012] Patent document 1: Japanese Patent Application Laid-Open No. 09-156357 Patent Document 2: Korean Patent No. 10-2227553 [Overview of the project] [Problems that the invention aims to solve]

[0013] The problem that this invention aims to solve is to provide a body cooling means that can be attached to widely used strollers to protect infants from heatstroke, and that can be reused by reattaching it to a new stroller even when the stroller is replaced. Furthermore, the invention aims to provide a body cooling means set that can be reused after the infant grows up by changing its form as cooling clothing for adolescents and adults.

[0014] The first aspect of the present invention is a body cooling means for regulating body temperature by bringing a refrigerant pipe into contact with the body, comprising a heat exchange device, a sheet body, and a mounting means, wherein the heat exchange device has a compressor, a condenser, and a blower housed in a casing, and a refrigerant pipe for delivering the refrigerant after heat exchange in the condenser to the outside of the casing, the refrigerant pipe is made of a flexible resin with a diameter that can be flexibly bent, the sheet body is a foldable sheet body and has an attachment means for the refrigerant pipe, the attachment means attaches the refrigerant pipe to the sheet body such that a part of the refrigerant pipe is a meandering flow path, and the sheet body and a part of the refrigerant pipe are sandwiched in an inner space between the left and right shaft portions that form the handle portion of a stroller The housing is retracted from the stroller to the seat, and the surface of the seat body to which the refrigerant pipe is attached is spread out and installed so that it faces the back of the infant. The mounting means has at least a shoulder strap, which is one of a shoulder strap and a ring, and the housing connected to the refrigerant pipe extending from the seat body installed in the seat can be attached to either the stroller or the person operating the stroller. This allows for temperature regulation of the infant and enables the user to choose whether to suspend the housing from the stroller's handle via the shoulder strap or the ring, or to attach the housing to the operator's shoulder via the shoulder strap, depending on the use of the stroller.

[0015] A heat exchanger consists of a compressor, condenser, and blower housed within a casing, connected by refrigerant piping. The refrigerant, compressed by the compressor, is sent to the condenser at a high temperature. As it passes through the condenser, it is cooled by heat exchange with the cooler outside air via the blower. This cooled liquid refrigerant is then sent to refrigerant pipes that extend to the outside of the casing.

[0016] In a well-known refrigeration cycle, this refrigerant pipe corresponds to an evaporator. The cooled liquid refrigerant evaporates within the pipe, becoming a gas that flows, lowering the temperature and absorbing heat from the body in contact with the pipe, thus regulating body temperature. Because the refrigerant pipe is made of resin, its heat transfer performance is smaller and more limited than that of a metal pipe, so there is no risk of excessive cooling of the body. A solenoid valve that functions as an expansion valve may be provided downstream of the condenser.

[0017] In this invention, since the refrigerant pipe is in direct contact with the body over clothing, there is less loss of cooling compared to conventional technology that blows in outside air. Therefore, the cooling function can be lower than that of a blower-type air conditioner, and the compressor and battery can be smaller. The length of the refrigerant pipe is not limited, but since shortening the pitch of the meandering flow path improves the efficiency of body temperature regulation, it is preferable to set it to approximately 2.0m to 3.5m. If the length of the refrigerant pipe is 2.0m or more, the pressure inside the refrigerant pipe will also be lower, which is preferable because it promotes the evaporation of the refrigerant. Even if the length is less than 2.0m, this can be addressed by reducing the amount of refrigerant charged.

[0018] Furthermore, the refrigerant pipes are made of flexible resin with a diameter that allows for easy bending. This makes it easy to bend the refrigerant pipes by hand to form a meandering flow path and attach them to the sheet material, while also allowing for soft contact with the body. The bendable diameter is not limited as it depends on the resin material that does not degrade with the refrigerant and the pipe thickness, but generally, a diameter of approximately 3 mm to 8 mm is less likely to cause discomfort when in contact with the body. More preferably, it should be 5 mm or less. In addition, the refrigerant pipes do not have any parts that can be damaged by touching them with bare hands, such as heat dissipation fins made of thin metal plates, as found in conventional evaporators. Therefore, even if infants or young children soil the refrigerant pipes with vomit, etc., they can be easily washed by hand.

[0019] Furthermore, since the seat itself is foldable, even with the refrigerant pipes attached, it can be folded in a direction that aligns with the straight section of the meandering flow path, allowing it to be installed by pulling only the seat and a portion of the refrigerant pipes into the seat area from the inner space sandwiched between the left and right axles that form the handle of the stroller. Therefore, when pushing the stroller, the refrigerant pipes do not protrude beyond the handle area, and the stroller can be used safely without the refrigerant pipes getting caught on obstacles. The seat may be installed only on the backrest of the seat, or it may be bent and installed from the seat surface to the backrest. If it is also installed on the seat surface, if the straight section of the meandering flow path is aligned with the transverse direction of the seat and only the bent section is gently curved, the refrigerant pipes will not be crushed and the flow of the refrigerant will not be obstructed.

[0020] Furthermore, since the seating area consists only of a foldable seat and thin refrigerant pipes, the seat can be removed even with an infant seated inside. This makes it highly convenient for use on public transportation, as the seat can be put away without having to hold the infant, even when folding the stroller to avoid inconveniencing other passengers. The seat can be rectangular in shape, but it may also be made into a garment shape to allow for conversion into cooling clothing. For example, a tunic, apron, or sleeveless vest would be suitable.

[0021] Furthermore, the housing that contains the compressor and other components is equipped with means for attaching it to the stroller body or to the person operating the stroller (parents or other guardians). Preferably, the exhaust port of the housing is directed to the left or right side of the stroller so as not to be directed towards the operator when the housing is attached. When the housing is suspended from the handle, the attachment means may be a shoulder strap or a ring that suspends it from a hook.

[0022] When the housing is to be attached to the operator's shoulders, a pair of shoulder straps that can be worn like a backpack are preferable, as they allow the operator to carry the housing on their back or around their waist. For example, when lifting a stroller, such as when climbing stairs, temporarily carrying the heavy housing on one's back means that only the lightweight seat and refrigerant pipes remain attached to the stroller, reducing the burden of lifting. When pushing the stroller, the shoulder straps can be attached by hanging them from hooks provided on the handle.

[0023] The first invention reduces the risk of heatstroke in infants during the summer and offers advantages not found in conventional technology, such as high versatility as it can be applied to any widely available stroller. Furthermore, even if the seat or refrigerant pipes are soiled by vomiting or other means, they can be easily cleaned, making hygiene management easy. In addition, the heat exchanger, which accounts for the majority of the weight, can be carried on the back, making it a user-friendly body cooling method even for women with less strength when going up and down stairs.

[0024] The second invention of the present invention is a body cooling means of the first invention, characterized in that the stroller is a stroller having a sunshade, the sunshade is attached to the seat by fasteners distributed at multiple locations, and the refrigerant pipe can be pulled out from a gap formed at an intermediate position between the multiple fasteners.

[0025] In the second invention, the target application is a baby stroller in which the sunshade part and the seat part are fastened by fasteners. The awning-shaped sunshade part is formed separately from the seat part and is fastened by fasteners such as buttons and bearing pipes so that it can be removed according to the season. Therefore, the seat part and the sunshade part do not adhere closely over the entire length, and a gap remains at the middle position of the fastener.

[0026] In the present invention, since the refrigerant pipe extending from the housing is of a small diameter, even a slight gap between the seat part and the sunshade part allows the refrigerant pipe to be inserted or pulled out from the gap. This brings an advantageous effect not present in the prior art, making it applicable to baby strollers with a sunshade part on the handle side and enhancing versatility. In addition, since the seat body is also foldable and has a flat shape, it is easy to pull out the seat body by removing some of the fasteners.

[0027] The third invention of the present invention is the body cooling means of the first invention, further comprising a first swing reduction means and a second swing reduction means. Each of the swing reduction means consists of a detachable fastening part and a fastened part. One of the fastening part and the fastened part is provided at a certain part of the baby stroller, and the other is provided on the outer surface of the housing. When the housing is suspended and attached to the handle part of the baby stroller by the attachment means, the first swing reduction means is fastened by two fastening parts and fastened parts on the left and right to suspend the upper side of the housing at two points, reducing the left and right swing of the housing accompanying the pushing and moving of the baby stroller. At the same time, the second swing reduction means is fastened by two fastening parts and fastened parts on the left and right to fasten the lower side of the housing, reducing the front and back swing of the housing accompanying the pushing and moving of the baby stroller.

[0028] According to the third invention, it includes a first swing reduction means and a second swing reduction means for reducing the swing of the housing. In a state where the housing is attached to the stroller by the attachment means, the engaging part and the engaged part are further engaged. Since the housing is supported by two means, the attachment means and the swing reduction means, the swing of the housing can be reduced as compared with the case where the housing is attached to the stroller only by the attachment means. The modes of the engaging part and the engaged part are not limited, but it is desirable that they are easy to attach and detach.

[0029] For example, if it is a belt having a side release buckle or a hook-and-loop fastener, etc., it is suitable because it is easy to engage the engaging part and the engaged part. In the case of a hook-and-loop fastener, if the hook-and-loop fastener is fixed to the outer surface of the housing and engaged with the hook-and-loop fasteners provided on the left and right handle parts, it is also easy to attach and detach. In addition, a form may be adopted in which the handle shaft part extending from the left and right of the stroller is the engaged part, a belt as the engaging part is provided on the housing side, the central part of the belt is wound around the handle shaft part, and both end parts of the belt are locked to the housing side. Thereby, the housing is difficult to swing, it is easy to push the stroller, and even if the stroller shakes strongly when crossing a step or the like, it is difficult to cause an emergency stop of the compressor or the like.

[0030] The fourth invention of the present invention is the body cooling means of the first invention, and further includes a dew condensation suppression means, and the dew condensation suppression means is characterized in that it covers the outer periphery of the refrigerant pipe exposed between the housing and the seat body.

[0031] According to the fourth invention, the outer periphery of the refrigerant pipe exposed from the housing to the seat body is covered by the dew condensation suppression means. The dew condensation suppression means may be a heat insulation cover for preventing dew condensation of the horizontal piping. In particular, it is preferable to have hook-and-loop fasteners along both edge parts, and it is easy to wind, attach, and detach. In addition, instead of the heat insulating material, it may be covered only with a flexible cloth body such as a towel. Thereby, even in a place with high humidity, the cooling efficiency is not easily reduced.

[0032] The fifth aspect of the present invention is a body cooling means of the first aspect, further comprising a fixing means for fixing a cloth body to the sheet body, wherein the fixing means detachably fixes the cloth body to the sheet body such that a refrigerant pipe is sandwiched between the sheet body and the cloth body.

[0033] According to the fifth invention, a towel or other easily washable cloth can be detachably fixed to the sheet body by a fixing means. The refrigerant pipe is sandwiched between the cloth and the sheet body, and is in direct contact with the body via the cloth. As a result, the cooling effect can be adjusted by changing the presence or thickness of the cloth, even without a mechanism to detect body temperature and control the compressor, and the structure of the heat exchange device can be simple. In addition, even if the fixed towel becomes dirty when going out, it can be easily and hygienically used by simply replacing it with a spare towel.

[0034] The sixth invention of the present invention is a body cooling means set for strollers that allows the body cooling means to be reused in a different form as a cooling garment, comprising the body cooling means of the first to fifth inventions with the shoulder straps removed, a body attachment means, a locking means, and a second attachment means, wherein the body attachment means consists of a pair of left and right second shoulder straps or a pair of left and right front panels and is provided on the seat body, and the locking means consists of a locking part and a locked part, with either the locking part or the locked part provided on the housing and the other provided on the side of the seat body opposite to the side to which the refrigerant pipe is attached The sheet body and the housing are locked together, and the second attachment means is provided on the inner surface of the sheet body or the cooling garment equipped with the front body at a different position from the first attachment means. The sheet body and the housing are attached to the body as a single unit, and when the garment is reused in a different form as the cooling garment, the first attachment means and the second attachment means allow the folding density of the refrigerant pipe or the attachment position of the refrigerant pipe to be changed so that a portion of the refrigerant pipe that was exposed between the housing and the sheet body can also be used for body temperature regulation.

[0035] According to the sixth invention, once the infant grows and the stroller is no longer needed, the body cooling means of the first to fifth inventions can be reused as cooling clothing. In the sixth invention, the body attachment means is a pair of left and right second shoulder straps attached to the seat body, or a pair of left and right front panels (the part of the garment that is located on the front of the body). Therefore, the seat body can be worn like clothing. If the second shoulder straps are detachable, they will not get in the way while the stroller is attached, and the second shoulder straps can also be used as a means to prevent swaying.

[0036] Furthermore, in the case of a front-facing garment, it is sleeveless and vest-like, making it easy to put on. It is also preferable to provide pockets on both the left and right front panels to store the main battery and a spare battery. In this case, even during long hours of outdoor work such as farming, or when changing batteries, the cooling garment does not need to be removed, and the weight is distributed between the front and back of the body, making it easy to move. The second attachment means can be provided on the inner surface of the front panel if there is a front panel, or on the inner surface of the sheet body in a different position from the aforementioned attachment means if there is no front panel.

[0037] The battery may be housed or attached to the casing, or it may be stored in a pocket of clothing, etc. A power distribution adapter may be attached to the battery to supply power to two separate systems: the heat exchanger and other electric devices. Other electric devices may include flashlights, smartphones, battery-operated mosquito coils, power tools, etc.

[0038] The sheet body forming the cooling garment is equipped with a locking mechanism for the housing on the outer surface opposite to the surface (inner surface) to which the refrigerant pipes are attached. Since the housing becomes integrated with the sheet body via the locking mechanism, the cooling garment is easy to put on and take off. The locking mechanism can be any well-known fastener such as hook-and-loop fasteners, zippers, or buttons. This creates new value by allowing the body cooling means to be reused as cooling garments even after the infant has grown up, providing an advantageous effect not found in the technology of prior literature, which only had the transient use value of a stroller. Of course, it can also be used as cooling garments when parents go out or work outdoors, even before the infant has grown up. Furthermore, by using the attachment mechanism and the second attachment mechanism together, the refrigerant pipes that were exposed on the outside of the sheet body in the body cooling means for strollers can also be used for body cooling.

[0039] The seventh invention of the present invention is a body cooling means set for strollers that allows the body cooling means to be reused in a different form as cooling clothing, comprising the body cooling means of the first to fifth inventions, a first body-mounting means, a second body-mounting means, and a second attachment means, wherein the first body-mounting means consists of at least one of a pair of left and right second shoulder straps, a torso strap, or a pair of left and right front panels and is provided on the seat body, the second body-mounting means consists of a pair of left and right shoulder straps and is provided on the housing, and the second attachment means However, the adhesive means are provided on the inner surface of the sheet body or the cooling garment equipped with the front body, at a position different from the adhesive means, and when the sheet body and the housing are sequentially attached to the body by the two body-attaching means, and the garment is reused in a different form as the cooling garment, the adhesive means and the second adhesive means make it possible to change the folding density of the refrigerant pipe or the attachment position of the refrigerant pipe so that a portion of the refrigerant pipe that was exposed between the housing and the sheet body can also be used for body temperature regulation.

[0040] The seventh invention differs from the sixth invention in that the seat and the housing remain separate, and the seat is worn first, and then the housing is carried on the back over it. The second body-mounting means is a pair of shoulder straps provided on the housing. Therefore, the shoulder straps, which are the second body-mounting means, can also function as the mounting means in the first invention.

[0041] If the shoulder strap is detachably attached to the housing, it can also function as a means of reducing oscillation as described in the third invention. Furthermore, since the housing is not secured to the sheet (cooling garment), it can be used by placing the housing on the ground instead of carrying it on one's back during tasks that involve little movement. This eliminates the need to constantly wear the heavy housing, resulting in the advantageous effect of reducing physical strain.

[0042] According to the first aspect of this invention, the risk of infants suffering from heatstroke in the summer can be reduced, and it offers advantageous effects not found in conventional technology, such as high versatility as it can be applied to any widely available stroller. Furthermore, even if the seat or refrigerant pipes are soiled by the infant due to vomiting, etc., they can be easily cleaned, making hygiene management easy. Moreover, the heat exchanger, which accounts for the majority of the weight, can be carried on the back, making it a user-friendly body cooling method even for women with less strength when going up and down stairs. According to the second invention of this invention, it can be applied to strollers that have a sunshade on the handle side, thereby increasing versatility, which is an advantageous effect not found in conventional technology. According to the third invention of this invention, the housing is less prone to shaking, making it easier to push the stroller, and even if the stroller shakes violently when going over steps or other obstacles, it is less likely to cause an emergency stop of the compressor. According to the fourth invention of this invention, cooling efficiency is less likely to decrease even in places with high humidity.

[0043] According to the fifth invention of this invention, the cooling effect can be adjusted by changing the presence or absence and thickness of the cloth, even without a mechanism to detect body temperature and control the compressor, and the structure of the heat exchange device can be simple. In addition, even if the towel that is fixed in place becomes dirty when going out, it can be easily used hygienically by simply replacing it with a spare towel. According to the sixth invention of this invention, a new value can be created by reusing the body cooling means as cooling clothing for a long period of time even after the infant has grown up, providing advantageous effects not found in the prior art which only had the transient use value of being a stroller. Furthermore, by using the attachment means and the second attachment means together, the refrigerant pipes that were exposed on the outside of the seat body in the body cooling means for strollers can also be used for body cooling. According to the seventh invention of this invention, in addition to the same effects as the sixth invention, it has the advantageous effect of being usable in a way that reduces physical strain.

[Figure 7] Side view diagrams of Type A and Type B strollers (reference diagram). [Modes for carrying out the invention]

[0045] The body cooling system for strollers is equipped with a heat exchanger, a seat, and a mounting mechanism. A refrigerant pipe extending from the heat exchanger is attached to the seat, and the seat is brought into contact with the infant's back to regulate body temperature and prevent heatstroke. Furthermore, the mounting mechanism allows the heat exchanger to be attached to either the stroller or the person operating the stroller, depending on how the stroller is being used.

[0046] This allows parents of infants and toddlers to reduce the weight burden of pushing the stroller by attaching the heat exchanger to it. On the other hand, when lifting and moving the stroller up stairs or elsewhere, the heat exchanger can be temporarily attached to the operator's body, reducing the weight of lifting the stroller itself, making it a user-friendly body cooling method even for women with weaker arm strength. Furthermore, by making the seat and heat exchanger attachable to the body, it creates new value as cooling clothing even after the stroller is no longer in use. [Examples]

[0047] In Example 1, a body cooling means 1 applicable to a stroller will be described with reference to Figures 1 to 4. The application to cooling clothing will be described later in Examples 2 and 3. Figure 1(A) shows an overall diagram of the body cooling means, Figure 1(B) shows an explanatory diagram of the internal structure of the heat exchanger, and Figure 1(C) shows a vertical cross-sectional view illustrating the usage state of the body cooling means.

[0048] Figure 2 shows an explanatory diagram of the mounting means and the oscillation reduction means. Figure 2(A) is a rear view showing the state before the housing is attached to the stroller, and Figure 2(B) is a rear view showing the state after the housing has been attached to the stroller. Figure 3 shows an explanatory diagram of the cross-section of the seat body, refrigerant pipe and attachment means. Figure 4 is an explanatory diagram of the fabric body fixing means, and Figure 4(A) is a plan view showing the seat body and fabric body side by side. Figure 4(B) shows the state after the fabric body has been fixed to the seat body as an enlarged cross-sectional view at position AA in Figure 4(A).

[0049] The body cooling means 1 comprises a sheet body 10 to which refrigerant pipes are attached, a heat exchanger 20, and a mounting means 30 that allows the housing of the heat exchanger to be attached to either a stroller or the body of the stroller operator (guardian of an infant) (see Figure 1(A)). The sheet body 10 has multiple attachment means 11 arranged in parallel on its inner surface. The refrigerant pipes 12 extending from the heat exchanger are routed in a meandering manner along the surface of the sheet body and are detachably attached to the sheet body 10 by the attachment means 11. Here, the number of attachment means 11, 11... in parallel is greater than the number of times the refrigerant pipes 12 are folded back, so that the attachment position of the refrigerant pipes can be arbitrarily selected and changed.

[0050] Furthermore, the seat body 10 is provided with elongated insertion holes 13 for drawing the refrigerant pipes 12 from the outer side to the inner side. Since these insertion holes 13 are narrower than the seat body 10, they function as diffusion restricting means that prevent the meandering refrigerant pipes 12 from diffusing to the left and right due to the elastic force of the resin. As a result, the refrigerant pipes 12 do not scatter beyond the width of the stroller 500, making it easy to install on the seat portion 501 of the stroller, and preventing the refrigerant pipes from getting tangled in the hands and feet of infants. The material of the seat body 10 will be described later with reference to Figure 3. In addition, as will be explained in detail in Example 3, the seat body 10 is provided with two pairs of body attachment means 210 on the left and right sides.

[0051] The heat exchange device 20 comprises a roughly rectangular prism-shaped housing 21, a refrigeration cycle 22 and its control device 23 built into the housing, and a replaceable battery 40 is externally connected to the housing 21 (see Figures 1(A) and 1(B)). A suitable example of such a heat exchange device 20 is, for example, the heat exchange device for body temperature regulating clothing sold by the present applicant. The detailed configuration of the heat exchange device will be described below.

[0052] The external dimensions of the housing 21 are approximately 30 cm in height, 20 cm in width, and 10 cm in thickness, and its weight, including the refrigeration cycle 24 and control device, is approximately 3 kg. The external dimensions and weight are illustrative and not limited thereto. On the back-facing surface of the housing 21, there are ring portions 31 at the four corners that function as means 30 for attaching to a stroller. An exhaust port 24 is provided on the surface opposite to the aforementioned back-facing surface. Multiple intake ports 25 are provided on both sides of the housing to improve intake efficiency. On the right side of the housing, there is a power supply cable 41 extending to a replaceable battery 40 and a power switch 42 (see Figure 2(B)). The supply pipe 14 and return pipe 15 of the refrigerant pipe 12 extend from the bottom surface of the housing. Note that the refrigerant pipe between the seat body 10 and the housing 21 can be shortened by extending the refrigerant pipe 12 from the top surface of the housing 21.

[0053] The refrigeration cycle 22 housed in the enclosure is connected in a ring in the following order: refrigerant pipe (return pipe) 14, compressor 26, condenser 27, solenoid valve 28, and refrigerant pipe (supply pipe) 15. The blower 29 is positioned between the condenser 27 and the exhaust port 24 to exchange heat between the compressed, high-temperature refrigerant and the outside air taken in from the intake port 25. The control device 23 only needs to be able to control the operation of the compressor 26, solenoid valve 28, and blower 29, and any well-known PLC (programmable logic controller) used in portable miniature refrigerators, etc., will suffice. The refrigerant, after exchanging heat with the outside air, passes through the solenoid valve 28 and changes state to a gas when it reaches the refrigerant pipe 12 due to a pressure drop. The entire refrigerant pipe is cooled by the heat transfer of this heat of vaporization. In other words, the refrigerant pipe functions as an evaporator in a normal refrigeration cycle.

[0054] Of the refrigerant pipes 12 that receive heat of vaporization, the portion attached to the sheet body 10 comes into contact with the infant's body through their clothing, thus cooling the body. Therefore, unlike conventional air conditioning systems, it is not necessary to cool the outside air, and a small, low-power refrigeration cycle 22 is sufficient, allowing the entire heat exchanger 20 to have a small and simple structure. Specifically, the power consumption of the heat exchanger 20 is approximately 65 W / h in an environment with an outside temperature of 35°C.

[0055] The length of the refrigerant pipe 12 is not limited, but it is preferable to have a length of approximately 2.0m to 3.5m, considering that it is easy to secure an internal volume that allows the refrigerant to evaporate and that it can be reused as a cooling garment as described later, although it is not limited to this length. In addition, since condensation may occur in the portion of the refrigerant pipe from the housing to the sheet body due to the outside air, it is preferable to provide a condensation suppression means 16. The condensation suppression means 16 can be any foamed resin sheet made of polyethylene resin or the like that is rolled into a cylindrical shape. The cylindrical foamed resin sheet is preferably made short so that the refrigerant pipe can be easily bent, and it is preferable to provide hook-and-loop fasteners or the like at both ends to make it detachable. If the refrigerant pipe is made longer, it is suitable for a cooling garment as in Example 2 described later. On the other hand, if the refrigerant pipe extends from the top surface of the housing and the portion extending between the housing and the sheet body is made shorter, there is an advantage that the portion where condensation occurs is shorter and the condensation suppression means can be omitted.

[0056] The replaceable battery 40 is connected to the housing 21 via a power supply cable 41 and a battery adapter 43, supplying DC power to the built-in refrigeration cycle 22, etc. Because the replaceable battery 40 is externally connected to the housing, even if the charge runs out while out, the heat exchanger can be continuously operated by replacing it with a spare battery 44. The specifications of the replaceable battery are a rated DC voltage of 18V, a maximum current of 6A, an electrical capacity of 7200mAh, and a weight of approximately 650g, and it is a replaceable battery for power tools.

[0057] With a battery of this capacity, the heat exchanger (65W / h) can be operated continuously for approximately 2 hours in an ambient temperature environment of 35°C. Because this replaceable battery is lightweight, it is also suitable for carrying as a spare battery 44. The battery adapter 43 has an arbitrary configuration, but it is provided to connect a replaceable battery conforming to the well-known JIS and PSE standards to the power supply cable 41 extending from the heat exchanger. Furthermore, if the battery adapter 43 is equipped with a USB terminal, it eliminates the need to carry a mobile battery for a cell phone, thus increasing convenience for everyday use.

[0058] Here, the mounting means 30, the first oscillation reduction means 50, and the second oscillation reduction means 60 will be described along with the procedure for attaching the body cooling means 1 to the stroller 500 (see Figure 1(C) and Figure 2). In Embodiment 1, the ring portion 31 provided on the upper side of the housing 21 functions as the mounting means 30 to the stroller. The horizontal handle portion 502 of the stroller is provided with a pair of left and right hook portions 503 to which the ring portion 31 is hooked in advance (see Figure 2). By suspending the pair of left and right ring portions 31 from their respective hook portions 503, the housing is supported at two points and lateral oscillation is reduced. Therefore, the pair of left and right ring portions 31 and hook portions 503 not only function as the mounting means 30, but also as the attachment portion and the attached portion of the first oscillation reduction means 50.

[0059] The means 30 for attaching the stroller to the guardian's body consists of a pair of shoulder straps 32, which are detachably attached to the upper and lower ring sections 31 and 34 via carabiners 33 at both ends. These shoulder straps 32 can also function as attachment points forming a second sway reduction means 60 (see Figure 2(B)). Specifically, the carabiners 33, 33 are removed from the left and right ring sections 31, 31 located on the upper side of the housing, the shoulder straps 32 are wrapped around the left and right handle shafts 504, 504, and the carabiners are then attached to the left and right ring sections 34, 34 located on the lower side of the housing. This secures the housing 21 and the stroller 500, reducing the swaying of the housing in the front-to-back direction.

[0060] By making the shoulder strap 32 function as a second sway reduction means 60, the left and right handle shafts 504 can function as attachment points for the second sway reduction means, eliminating the need to add attachment parts to the stroller later. Of course, the handle shafts 504 may also be equipped with rings to which carabiners can be attached, allowing them to function as attachment points. The attachment parts are not limited to carabiners and may also be well-known side-release buckles, etc.

[0061] The procedure for installing the body cooling device on the stroller is described below. First, remove the fasteners 507 connecting the backrest 505 and the sunshade 506 of the stroller (see Figures 1(C) and 2(A)). Insert the seat body 10 extending from the housing 21 through the gap between the backrest 505 and the sunshade 506, and spread it out so that the side to which the refrigerant pipe 12 is attached is in contact with the infant's back. Since the seat body 10 is thin, this can be done even with the infant seated. In this case, slightly raise the infant's back from the backrest to create a gap for inserting the seat body, and then insert the seat body. If you want to install the seat body from the seat surface to the backrest, adjust the orientation of the seat body so that the straight section of the meandering flow path of the refrigerant pipe extends across the seat body, and ensure that the bent section of the refrigerant pipe is gently curved between the seat surface and the backrest so as not to crush the refrigerant pipe, thereby not obstructing the flow of the refrigerant.

[0062] Next, fasteners 507 connecting the sunshade and the backrest are secured, leaving only the refrigerant pipe 12 and condensation suppression means 16 extended from the stroller (see Figure 2(A)). Then, the upper rings 31, 31 are attached by hooking them onto the hooks 503 provided on the horizontal handle 402. The replaceable battery 44 can be placed in the parent's handbag or clothing pocket, but it is preferable to place it in the basket 509 located below the stroller seat, as this helps stabilize the stroller's center of gravity (see Figure 1(C)).

[0063] Furthermore, the carabiner 33 on the upper side of the shoulder strap 32 is detached from the ring portion 31 and wrapped around the left and right handle shafts 504, while the carabiner 33 is hooked onto the lower ring portion 34 (see Figure 2(B)). The housing 21 is in a state where lateral and forward / backward swaying is reduced by the two hook portions 503 provided on the horizontal handle portion 502 and the left and right shoulder straps 32, so the center of gravity balance is less likely to be disrupted when pushing the stroller, resulting in good operability, and it is less likely to cause an emergency stop due to the tilting of the compressor. In addition, the housing 21 and the refrigerant pipes 12 do not protrude beyond the left and right handle shafts 504, 504, so unforeseen incidents such as the housing coming into contact with other people or the refrigerant pipes getting caught do not occur.

[0064] Here, the material and thickness of the sheet body 10, the material and thickness of the attachment means, the material and diameter of the refrigerant pipe, etc., will be specifically explained with reference to Figure 3. Figure 3 shows an explanatory diagram of the cross-section of the sheet body 10, the attachment means 11, and the refrigerant pipe 12. The material of the sheet body 10 can be any flexible fabric used for clothing, such as polyester resin or acrylic resin. Alternatively, it may be a foamed resin sheet made of polyethylene resin or the like, which is wrapped around the pipe as an insulating cover when the refrigerant piping is laid horizontally. A foamed resin sheet is preferable because, due to its insulating properties, it is difficult for cold and heat to dissipate to the back side of the sheet body, and it also suppresses the occurrence of condensation.

[0065] The thickness of the sheet body 10 is not limited and can be any thickness that allows it to be flexibly folded according to its material. In the case of foamed polyethylene resin sheets, if the foaming ratio is 30 times, a thickness of approximately 10 mm or less is preferable because it is easy to fold and does not break when folded. Furthermore, to enhance the design and allow for conversion into cooling clothing, the sheet body may be made of the same material used for sleeveless vests.

[0066] The attachment means 11 detachably attaches the refrigerant pipe 12 to the sheet body using a pair of hook-and-loop fasteners that extend in a strip-like manner. Specifically, one hook-and-loop fastener 17 is adhered to the sheet body 10 so that it functions as the attachment member. Furthermore, the base end edge of the strip-like body 18 is fixed to the sheet body 10 by sewing or the like, and the other hook-and-loop fastener 19 is adhered to the tip end edge so that the strip-like body functions as an attachment member (see the attachment means on the right in Figure 3). When attaching the refrigerant pipe 12, the hook-and-loop fasteners 17 and 19 are attached to each other so that the strip-like body 18 covers the refrigerant pipe 12 (see the attachment means 11 on the left in Figure 3).

[0067] The material of the strip-shaped body 18 is not limited and may be a woven fabric made of natural fibers, a nonwoven fabric made of chemical fibers, or a resin film, etc. The thickness of the strip-shaped body 18 is preferably thin, as long as it has sufficient strength to prevent breakage, in order to improve heat transfer efficiency. Furthermore, the attachment means 11 is not limited to hook-and-loop fasteners, but may be fasteners such as buttons. The shape of the attachment means is not limited to extending in a strip-like manner, and of course, short hook-and-loop fasteners may be distributed and attached only to key points.

[0068] The material of the refrigerant pipe 12 may be any fluororesin or the like that does not become brittle due to the refrigerant, but is not limited to this. The refrigerant pipe may also be a double pipe with the inner and outer layers made of different resins. The diameter of the refrigerant pipe is preferably 3 mm to 10 mm. In particular, a diameter of 5 mm or less is preferable as it is easier to bend. If the diameter exceeds 10 mm, the bumps that come into contact with the back of an infant will be larger, so it is preferable to use a cloth body as described later in combination to reduce discomfort. The type of refrigerant is not limited, but isobutane (R-600a) used in portable mini refrigerators or R-1234ze used in turbo chillers are preferable because they have excellent environmental performance.

[0069] Next, the fabric fixing means 70, which can have any configuration, will be described with reference to Figure 4. Figure 4(A) is a plan view showing the sheet body 10 and the fabric body 71 side by side, and Figure 4(B) is an explanatory diagram showing a cross-section at position AA. The fabric fixing means 70 is shown here as a hook-and-loop fastener, but is not limited to this. For example, it may be a fastener such as a button, or it may be simply fixed with a clamping device, or the fabric may be made into a bag shape into which the sheet body is inserted to serve as the fixing means. The fabric may be any easily washable fabric such as a towel. If the fabric is in the form of a bag, it may be a waterproof or water-repellent fabric made of nylon or polyester resin.

[0070] When hook-and-loop fasteners are used as the fixing means 70, the hook-and-loop fasteners 72 on the attachment side are adhered to the four corners of the sheet body 10, where they do not significantly affect the arrangement of the refrigerant pipes. For the fabric body 71, the hook-and-loop fasteners 72 on the attachment side are adhered to the four corners so as to align with the position of the hook-and-loop fasteners 73 on the attachment side. By attaching the hook-and-loop fasteners together, the sheet body 10 and the fabric body 71 can be easily integrated. Hook-and-loop fasteners are suitable because they can be easily fixed to commercially available fabrics, etc., as long as they have a heat-sealed layer on the side opposite to the attachment surface, making them easy to replace frequently. [Examples]

[0071] In Example 2, a body cooling means set 2, which can be repurposed as a cooling garment 100 from a body cooling means 1 for a stroller, will be described with reference to Figure 5. Figure 5(A) shows a plan view of the inner surface of the cooling garment 100. Figure 5(B) shows a plan view of the outer surface of the cooling garment 100. Figure 5(C) shows an explanatory diagram of a person wearing the cooling garment 100, from a side view of the upper body. The heat exchanger 20 has the same configuration as in Example 1, so its description will be omitted.

[0072] The cooling garment 100, which is an adaptation of the body cooling means 1 described in Example 1, is equipped with a body attachment means 110 and a locking means 120 for integrating the heat exchange device 20 with the cooling garment (see Figures 5(A) and 5(B)). The body attachment means 110 consists of a right front panel 112 and a left front panel 113 that are detachably attached to the sheet body 10 by first fasteners (zippers) 111 provided on both sides. The first fasteners 111 are provided from the lower end of the side edge to near the center of the upper edge so that the sheet body 10 and the front panels 112 and 113 form a sleeveless jacket. Here, the sheet body and the front panels are integrated by fasteners (zippers) because they are difficult to disengage and easy to attach and detach, but the form is not limited to this and they may be integrated by hook-and-loop fasteners, buttons, etc.

[0073] Furthermore, the left and right front panels 112 and 113 are equipped with a second fastener 114 for fastening them together in front of the body, and armholes 115. In addition, a second attachment means 116 is provided on the inner surface of each front panel so that the refrigerant pipe 12 can be routed down to the abdominal side. By attaching the refrigerant pipe 12 to the second attachment means, the refrigerant pipe that was exposed on the outside of the seat body in the stroller body cooling means 1 can also be used for body cooling. Because the upper body is cooled in a distributed manner, no part of the body becomes extremely cold, and body temperature can be regulated in a balanced manner. The form of the second attachment means 116 can be the same as the attachment means 11 provided on the seat body 10.

[0074] The locking mechanism 120 of the heat exchanger 20 consists of a locking portion 121 (Figure 5(B)) provided in an annular shape on the outer surface of the sheet body and a locking portion 122 (see Figure 5(C)) provided in an annular shape on the surface facing the back of the housing. Here, it is configured to be locked by a third fastener, but the form is not limited to this and may be a hook-and-loop fastener or a button, etc. Furthermore, each front panel is provided with a pocket 130 into which a replaceable battery or a spare battery can be inserted. Therefore, it is easy to replace the spare battery and is suitable for long hours of outdoor work.

[0075] When putting on the cooling garment 100, the housing 21 is first secured to the outer surface of the sheet body 10 using the locking means 120 to form an integrated unit. Then, the garment is worn by putting both arms through the armholes 115 on both sides, as if putting on a jacket, and carrying the housing 21 on the back. Finally, by closing the second zipper 114 located at the abdomen, the housing 21 of the heat exchanger becomes tightly attached to the body, completing the garment's attachment. If the front panels 112 and 113 are available in multiple sizes, the cooling garment 100 can be used by people with different body types.

[0076] In the case of the invention of Example 2, the housing is integrated with the cooling garment, making it easy to carry on the back, and there is also the advantage that the entire length of the refrigerant pipe can be housed inside the cooling garment. If the refrigerant pipe is to extend from the top surface of the housing, the top and bottom of the sheet body 10 can be reversed. Furthermore, as mentioned above, the sheet body is made of a flexible fabric, and the refrigerant pipe is also flexible and can be bent, so it can be reused as a comfortable cooling garment. The housing may be carried not only on the front but also on the back with a pair of shoulder straps on the left and right. In either case, when the housing is carried on the back, the internal refrigeration cycle is less likely to tilt from the horizontal, so emergency stops are less likely to occur. [Examples]

[0077] In Example 3, a body cooling means set 3 in which the housing 21 and the cooling garment 200 are attached to the body separately will be described with reference to Figure 6. Figure 6(A) shows a plan view of the sheet body 10 and the first body attachment means 210, and Figure 6(B) shows an explanatory diagram of a side view of the upper body when a person puts on the cooling garment 200 and the housing 21 in order. Figure 6(C) shows an explanatory diagram in which the refrigerant pipe 12 extends from the top surface of the housing 21.

[0078] The cooling garment 200, which utilizes the body cooling means 1 described in Example 1, is configured so that a separate sheet body 10 and housing 21 are worn sequentially on the back (see Figures 6(B) and 6(C)). In addition to the configuration described in Example 1, the sheet body includes a pair of upper and lower torso bands as the first body-mounting means 210. Here, since the front body is not attached separately, the number of times the refrigerant pipes are folded is increased compared to Example 1, thereby shortening the exposed portion of the refrigerant pipes 12 located between the housing 21 and the cooling garment 200 (see Figure 6(A)).

[0079] Specifically, the attachment means 11, which was not used when applied to the stroller, is also used to increase the number of folds and thus increase the density of the refrigerant pipes. When the refrigerant pipes 12 extend from the bottom of the housing 21, the refrigerant pipes 12 are drawn into the inside of the seat body 10 from the position of a person's waist (see Figure 6(B)).

[0080] On the other hand, if the refrigerant pipe 12 extends from the top surface of the housing 21 and the refrigerant pipe extending between the housing and the sheet body 10 is shortened (see Figure 6(C)), the position where the refrigerant pipe is attached to the sheet body does not need to be changed between stroller use and cooling clothing use, and the number of attachment means 11 can be reduced. In this case, the sheet body should be worn so that the insertion hole 13 for drawing the refrigerant pipe into the inside of the sheet body is located near the neck. This makes it easy to use the body cooling means of Embodiment 1 as cooling clothing when parents go shopping or do other errands while leaving their infants at daycare or with family.

[0081] The first body attachment means 210 is a body belt attached to the seat body 10, and is equipped with a carabiner 211 at its base end and a side-release buckle 212 at its tip end. The carabiner 211 is detachably attached to a ring portion 213 provided on the seat body 10. The side-release buckle 212 consists of a pair of male members 213 and female members 214. It is a locking device in which the male member can be inserted into and fitted into the female member. The female member also has an opening 215 on its side, so that when the male member is fitted, a part of the male member is exposed, and the fitting can be released by pressing the exposed part with a finger.

[0082] Furthermore, in the body cooling means set 3, the housing is separate from the cooling garment, and therefore the housing is equipped with a second body attachment means 220. The second attachment means 220 is a shoulder strap 32 which constitutes the attachment means 30 described in Example 1. When putting on the cooling garment 200, first place the sheet body 10 against your back and fasten the two side release buckles 212 at the top and bottom in front of your body. Next, use the shoulder strap 32, which is the second attachment means 220, to carry the housing 21 on your back like a backpack.

[0083] In Example 3, since the sheet body 10 is only on the back of the body, it is easy to wear under work clothes. Therefore, even if the material of the sheet body is not fire-resistant or cut-resistant, it can be used for work that produces sparks, such as welding, or logging work using a chainsaw, by wearing it under work clothes, making it highly versatile. Moreover, even in civil engineering work or painting work, where clothing is likely to get dirty, hygiene management is easy because the sheet body does not get dirty. Also, since the housing and the cooling garment are separate, it is possible to work with the housing placed on the ground.

[0084] (others) In Example 2, the front panel was used as an example of a means of attachment to the body for ease of understanding, but it is not limited to this, and the sheet body may also be equipped with a shoulder strap. Furthermore, the front panel may be molded integrally with the sheet body beforehand and made into a single sheet that can be opened and closed with a zipper from the shoulder to the neck. In this case, it may be used by wrapping the infant in the sheet body, or the front panel portion may be folded to the opposite side. In addition, the first zipper for fastening the front panel to the sheet body may have its side edge position omitted and extend from the neck to the shoulder, and the side edge may be configured to be tightened with a belt or the like. • In Example 3, a torso belt with a side-release buckle was exemplified as the first body attachment means for ease of understanding, but it is not limited to this. For example, it may be a shoulder strap (which may also be in the form of a cord), or it may be a front panel as in Example 2. • In the embodiment, for ease of understanding, the configuration of the heat exchanger is shown excluding transformers, etc., but it goes without saying that transformers, etc. may be included. It goes without saying that the "means" in the present invention, such as "body cooling means," "adhesion means," and "attachment means," may be replaced with "device," "component," "tool," etc. In this invention, a Type A stroller refers to a product known as a "pram" or "carrycot" in English-speaking countries, while a Type B stroller refers to a product known as a "stroller" or "buggy." The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The technical scope of the present invention is indicated by the claims, not limited to the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended.
