FIG. 1 is a cross-sectional view of a shoe having a foot cooling function according to an embodiment of the present invention. FIG. 2 is a view showing a foot region where a cooling function is performed according to an embodiment of the present invention, FIG. 3 is a perspective view illustrating a shoe having a foot cooling function according to another embodiment of the present invention, FIG. 4 is a view showing a foot portion where a cooling function is operated according to another embodiment of the present invention, and FIG. Is a cross-sectional view showing a cross section of the refrigerant block of FIG. 3;

One embodiment of the present invention is constituted by constituting at least one pocket 111 in the shoe 100 and inserting the refrigerant block 110 into the pocket 111 as shown in FIG.

1, a pocket 111 is provided on the inner side of the upper part of the shoe 100 except for the bottom of the shoe 100 with a solid sole, so that a cloth or thin leather is accommodated therein, and the pocket 111 The refrigerant block 110 is inserted into the inside of the storage compartment.

Generally, the bottom of the shoe 100 is formed of a hard material having excellent abrasion resistance and durability. Therefore, when the pocket 111 is formed on the bottom of the shoe 100 and the refrigerant block 110 is inserted, A pocket 111 is formed on the upper side of the shoe 100 molded with a thin leather material and a thin coolant block 110 is inserted into the pocket 111. [

The body of the refrigerant block 110 is formed of a metal material such as stainless steel which is excellent in thermal conductivity and can withstand high pressure and has a space formed therein. Is charged.

The refrigerant is filled in the refrigerant block 110 at a high pressure and then sealed to maintain the liquid state inside the refrigerant block 110 do.

It is preferable that the refrigerant in the liquid state is filled in the refrigerant block 110 by about 30 to 70% by volume and 30 to 70% by volume of the refrigerant block 110 is left in the empty space.

If the refrigerant is filled with less than 30% by volume of the refrigerant in the refrigerant block 110, the cooling effect can not be properly observed. If the refrigerant is filled in the refrigerant block 110 in an amount exceeding 70% by volume, It is preferable to fill the inside of the coolant block 110 with a liquid coolant so as to be 30 to 70% by volume.

The refrigerant in the refrigerant block 110 at room temperature is cooled by evaporation of a certain portion of the refrigerant into the empty space of the refrigerant block 110 due to the nature of vaporization, .

Also, since the refrigerant filled in the refrigerant block 110 is shaken by the kinetic energy generated in the process of walking or running while wearing the shoe, the molecular motion of the refrigerant becomes active, and as a result, the refrigerant is vaporized more actively, Absorbs the temperature of the shoe to further cool the temperature inside the shoe to cool the foot.

In other words, when exercising while wearing the shoe of the present invention, it is possible to cool the foot more effectively, thereby more effectively suppressing sweating on the foot.

However, it is preferable to use a secondary refrigerant brine refrigerant in order to prevent the occurrence of a safety accident.

Calcium chloride (CaCl ₂ ) in inorganic brine maintains liquid state at -50 ° C, is cheap, and has low causticity. An organic brine may be used by mixing alcohol with propylene glycol solution.

As shown in FIG. 1, when pockets 111 are formed on both sides of the upper portion of the shoe 100 and shoes having the refrigerant blocks 110 inserted therein are put on the pockets 111, Keep your feet cool.

3 is a perspective view illustrating a shoe having a foot cooling function according to another embodiment of the present invention. Another embodiment of the present invention is configured to cool a user's foot by forming a receiving groove in the insole 112 of the shoe 100 and inserting a refrigerant block filled with the refrigerant therein.

3, a first receiving groove 113 is formed in a groove shape in a front portion (a portion where a toe is located) of the insole 112 and a center portion (a portion where a central arch portion of a sole is located) of the insole 112, The second receiving groove 114 is formed in a groove shape.

The first and second refrigerant blocks 120 and 130 formed in the first and second receiving grooves 113 and 114 are inserted into the first and second receiving grooves 113 and 114, respectively.

The first and second refrigerant blocks 120 and 130 are filled with the same refrigerant as the first embodiment of the present invention.

In another embodiment of the present invention configured as described above, when the user wears the shoe, the first refrigerant block 120 is positioned under the toe portion of the user, thereby intensively cooling the toe portion as shown in FIG.

Since the toes are in close contact with each other, sweat is generated a lot in the summer, and moist and ventilation is not performed properly. Therefore, mold is generated and athlete's foot is frequently generated. 1 The refrigerant block 120 concentrates the cooling of the toe portion, thereby suppressing the occurrence of sweat and keeping the toe portion in a healthy state.

The upper surface of the second refrigerant block 130 is configured to protrude from the center of the upper surface with a predetermined curvature so that the upper surface of the second refrigerant block 130 is closely attached to the depressed arch portion in the central portion of the sole.

The second refrigerant block 130 configured as described above cools closely to the arch portion at the center of the sole and cools the arch portion at the center of the sole as shown in FIG.

Since the distance between the epidermis and the blood vessel is shortest in the foot depressed at the center of the plantar surface, cooling of the plantar arch part can cool the entire plant quickly.

However, when the insole 112 is not provided or is thin, a receiving groove is formed in the sole 100 of the shoe 100. In this case, the receiving groove is formed in the insole 112 of the shoe, And inserting the refrigerant block into the receiving groove.

Since the first and second refrigerant blocks 120 and 130 are formed of a metal material, the first and second refrigerant blocks 120 and 130 may feel a foreign body feeling and inconvenience on the feet contacting the first and second refrigerant blocks 120 and 130, Can feel too cold.

3 and 5, a plurality of protrusions 121 and 131 are formed on the upper surface of the first and second coolant blocks 120 and 130 and a plurality of protrusions 121 and 131 are formed between the protrusions 121 and 131, The heat insulating material 122 or 132 such as a material or a sponge is formed to have the same height as the protruding portions 121 and 131.

The inside of the protrusions 121 and 131 communicates with the inner space of the first and second refrigerant blocks 120 and 130, thereby exerting a cooling function. That is, the first and second refrigerant blocks 120 and 130 are reduced in contact area with the soles of the foot so that the user can feel less cold, and a certain portion of the surface of the first and second refrigerant blocks 120 and 130 is made of the same material as the surface of the insole 112, So that foreign matter can be minimized.

The shoe having the foot cooling function of the present invention configured as described above can prevent heat stroke on hot summer days by coolly cooling the foot using liquid refrigerant without using a complicated electric / electronic device, So that the foot can always be kept in a healthy state.

In addition, since the structure is simple, the production cost can be reduced, and there is no failure, so that it can be used semi-permanently without the maintenance cost.
