In step S12, it is determined whether the difference between the "body temperature" obtained in step S10 and the "outside air temperature" obtained in step S11 is equal to or more than a preset threshold.

Next, when the determination result is "No", the process proceeds to step S13, and the electric pump 20 is controlled to generate electric power that sends out the liquid medium 200 at a normal flow rate, and then the process proceeds to step S15.

On the other hand, when the determination result is "YES", the electric pump 20 is controlled to generate electric power that sends out the liquid medium 200 in a state where the flow rate is increased more than usual, and then proceeds to step S15.

In step S15, it is determined whether the difference between "body temperature" and "outside air temperature" is below a threshold value.

Next, when the determination result is "No", the process returns to step S14, and the state in which the flow rate is increased more than usual is continued.

In this way, in accordance with the body temperature of the user or the outside air temperature, it can be handled in a state where the flow rate of the liquid medium 200 is increased in the case where continuous cooling or continuous warming is required.

On the other hand, when the determination result is "YES", after the drive of the electric pump 20 is stopped in step S16, the process returns to step S10, and a series of processes are repeatedly performed.

Thereby, the electric pump 20 can be stopped in a state where cooling or warming is not required according to the user's body temperature or outside air temperature, and the body can be prevented from being too cold or too warm. In addition, by temporarily stopping the electric pump 20, the consumption of the battery 50 as a power source can be suppressed, and the driving time of the entire system can be obtained.

The pillowcase 920A shown in FIGS. 11 and 12 has a structure that sandwiches two pieces of cloth 921a and 921b cut into a shape that can cover the upper surface of the pillow 940 (see FIG. 13). It snakes into a loop-shaped flexible tube 100. Furthermore, as described above, by driving the electric pump P, the cooling water 200 flowing from the flexible tube 100B in the direction of D2a is circulated in the meandering flexible tube 100 in the direction of D2, and the first Portion 100a is discharged in the direction of D2b. Thereby, as shown in FIG. 13 and FIG. 14, the head h10 and the neck h11 of the user H can be cooled.

As the fabrics 921a and 921b of the pillowcase 920A, it is preferable to use a soft material (for example, a three-dimensional structure mesh (two-needle interlaced) fabric) that can absorb the unevenness of the position where the flexible tube 100 is arranged. In addition, a seam allowance 930 is provided on the peripheral edges of the fabrics 921a and 921b, and can be closed by sewing.

In addition, a sponge, cotton, or the like may be filled between the cloths 921a and 921b to improve the user's touch when the user h places the head h10 thereon (see FIGS. 13 and 14).

In addition, ropes 922 for fixing the pillowcase 920A to the pillow 940 are provided at left and right ends of the pillowcase 920A.

In this embodiment, the pillowcase 920A and the pillow 940 are separated, but the present invention is not limited to this, and the pillowcase 920 and the pillow 940 may be provided in an integrated state.

Next, the pillowcase 920B will be described with reference to FIGS. 15 and 16.

Fig. 15 is an explanatory view of the pillowcase 920B, and Fig. 16 is a sectional view taken along the line B-B of Fig. 15 of the pillowcase 920B.

In the pillowcase 920B shown in FIGS. 15 and 16, the flexible tube 100 (100A, 100B) is branched into two flexible tubes 100C and 100D at the branch portions 150 and 151, and a plurality of the flexible tubes 100C and 100D are arranged in the pillowcase 920B. It is arranged in a loop shape. In addition, other structures and methods of use are the same as those of the pillowcase 920A. According to the pillowcase 920B, the head h10 and the neck h11 of the user H can be cooled more effectively.

In addition, in the pillowcase 920B shown in FIGS. 15 and 16, the flexible tube 100 is branched into two, but it is not limited to this, and it may be branched into three or more, and each branch may be flexible. The tubes are arranged in a loop.

In this embodiment, the pillowcase 920B and the pillow 940 are separated, but the present invention is not limited to this, and may be provided in a state in which the pillowcase 920B and the pillow 940 are integrated.

The sheets 936a and 936b are formed of, for example, a soft vinyl chloride resin.

An elastic sheet 937 made of an ether sponge or the like having a predetermined thickness (for example, about 5 mm) is sandwiched between the sheets 936a and 936b. This prevents the water path 923 from being crushed when the user H places the head h10.

As shown in FIG. 17, the water path 923 can be formed by forming linear welding portions 950 a that are staggered from each other between the sheets 936 a and 936 b. Further, the spot-shaped welded portions 950b are formed at predetermined intervals along the water path 923, and the sheets 936a and 936b are fixed.

In addition, the peripheral portions (welded portions) 950c of the sheet pieces 936a and 936b are welded to seal the gap between the sheet pieces 936a and 936b.

In addition, the welding processing of each of the welding portions 950a to 950c can be performed by pressing a heated predetermined shape welding torch or assisting device from the outside of any of the sheets 936a and 936b.

In this embodiment, the water pillow sheet 920C is separated from the pillow 940, but the present invention is not limited to this, and the water pillow sheet 920C and the pillow 940 may be provided in an integrated state.

In addition, the cooling water 200 injected from the end of the flexible pipe 100B in the direction of D2a is driven by the electric pump P, and circulates along the path of the water path 923 in the direction of D2d, and flows from a part 100a of the flexible pipe. discharge.

In this way, instead of the flexible tube, the water pillow piece 920C has a structure in which the water path 923 is formed by welding, which can reduce the manufacturing cost. In addition, since the flow rate of the cooling water 200 circulating in the water path 923 can be increased compared to the structure using a flexible pipe, the head H10 and the neck h11 of the user H can be cooled more effectively.

Here, FIG. 18 is a graph showing the temperature change of the cooling water circulating through the pillow cases 920A and 920B or the water pillow 920C.

In the graph, the drawn line L1 represents the temperature near the cooling water inlet of the pillow cases 920A, 920B or the water pillow 920C, and the drawn line L2 represents the measurement result of the temperature near the cooling water outlet of the pillow cases 920A, 920B or the water pillow 920C.

In this way, the average value of the temperature near the cooling water inlet and the temperature near the cooling water outlet is calculated from the measurement result of the temperature measurement over a fixed time, and the intermittent operation of the electric pump P can be controlled based on the calculated value.

Thereby, the average temperature of the cooling water 200 circulating in the pillow cases 920A, 920B or the water pillow 920C can be controlled more dynamically than in the case where the electric pump P is controlled only by the change in voltage.

In addition, the flow path 1256a can be formed in the flow path module 1256 to meander. Thereby, the efficiency of heat exchange can be improved.

In addition, the cooling unit 1201 includes a heat sink 1252 that emits heat from the heating surface of the thermoelectric conversion element 1254 and is formed of aluminum or the like; and a cooling fan that is disposed opposite to the heat sink 1252 for cooling Electric fan 1251.

Further, a heat-insulating material 1253 made of a heat-insulating foamed material or the like is provided between the cooling radiator 1255 and the heat-radiating radiator 1252. This makes it possible to suppress heat from being transmitted to the cooling radiator 1255 side.

The components of the cooling unit 1201 except the electric fan 1251 can be integrally fixed by screws 1257 screwed from the flow path module 1256 side.

The cooling unit 1201 is housed in a casing 1280 having an air inlet (not shown) as shown in FIG. 25.

The casing 1280 and the electric fan 1251 are fixed to a side wall 1700a of the casing 1700.

FIG. 28 is a schematic explanatory diagram of a water flow in the cooling device 1010.

As shown in Figs. 26 and 27, the resin case 1700 is composed of two half bodies 1700A, 1700B, and the like that can be divided into two.

In the half body 1700A, an exhaust port 1285 formed by a plurality of slits is formed on the right side wall in the drawing.

Further, an air intake port 1702 formed by a plurality of slits is formed on the front side and the back side (not shown) of the half body 1700A in the drawing.

An accommodating portion of the operation unit 1011 and the operation portion 1011a is formed above the other half body 1700B.

The slit provided in the third region A3 is provided so that the exhaust gas from the third region A3 is located on the first region A1 side. Thereby, the exhaust from the third region A3 is performed along the exhaust from the first region A1. Therefore, the exhaust from the third region A3 can be smoothly performed without installing a fan in the third region A3.

The position where the slit is provided may be separated from the position of the operation portion 1011. In use, the operation part 1011 is placed near the operator, so the slit exists at a position separate from the operator. Therefore, the warm air is exhausted from a position separated from the operator, so the warm air does not easily flow to the operator. Furthermore, a guide can be provided on the exhaust side to prevent the exhaust gas from getting around to the operator side.

Further, below the inside of the housing 1700 formed by coupling the half bodies 1700A and 1700B, a first area A1 for storing the cooling unit 1201, a tank 1203 for storing the cooling water 200, and a supply from the tank 1203 are formed.

The power supply unit 1016 may also be fixed in the third area A3 with screws, or a groove in which the power supply unit can be inserted is provided in the third area A3, and it is slid to be received in the groove.

The first region A1 and the second region A2 are separated by a partition wall K1.

Thereby, the first area A1 forming the air passage through which the cooling unit 1201 and the like can pass is separated from the second area A2 provided with the tank 1203 through which the cooling water HW flows into and the electric pump 1202 which is one of the heat sources. , And the heat exchange efficiency of the cooling unit 1201 can be improved.

The first region A1, the second region A2, and the third region A3 are separated by partition walls K2a and K2b.

In this way, in the event that cooling water leaks from the cooling unit 1201 or the tank 1203 in the first area A1 or the second area A2, the cooling water can be prevented from entering the third area A3 that houses the power supply unit 1016, and can be preliminarily used. Prevent leakage accidents and improve safety.

Next, once the cooling device 1010 having the above structure is started, the electric pump 1202 will be driven. As shown in FIG. 28, the higher-temperature cooling water HW returned from the water-cooling pillow 1500 through the flexible tube 1012 will flow in the direction of D200 and Temporarily stored in tank 1203. Since the cooling water HW is temporarily stored in the tank 1203, air does not enter the electric pump 1202, and the electric pump 1202 can be prevented from idling.

Next, the cooling water flows through the electric pump 1202 in the direction of D201 and D202, and flows into the flow path module 1256 of the cooling unit 1201. The cooling water CW cooled by the cooling unit 1201 is sent out in the direction of D203, and is sent to the water-cooling pillow 1500 through the flexible pipe 1012. With this circulation of the cooling water HW and CW, the water cooling pillow 1500 can be continuously cooled.
