Description

Technical Field [0001] The present invention relates to a functional shoe having cooling or heating means,

The present invention relates to a cooling or heating apparatus for a shoe, and more particularly, to a shoe for cooling or heating a shoe by lowering the temperature of the shoe when the outdoor temperature is high as in the summer, Cooling or warming means.

The present invention relates to a shoe having a natural circulation cooling / heating system, which provides a cooling means for cooling the inside of a shoe when the outside temperature is high, such as a summer season, so as to keep the feet of the wearer in a comfortable state, So that the foot structure can be prevented to prevent skin diseases.

Shoes are intended to protect the wearer's feet. In winter, feet are cold due to low outside temperatures. In summer, temperatures inside shoes are considerably high due to high outside temperatures.

When the shoe is cold like the winter season, it is dry, so there is not much problem causing the skin disease. However, when the outdoor temperature is high as in the summer season, the shoe has considerable problems due to bad ventilation and the like.

As described above, when the outdoor temperature is high, the temperature inside the shoe becomes high, so that a lot of sweat is generated. As a result, the inside of the shoe is always in a humid state, and the health of the foot is considerably deteriorated. When perspiration occurs, perspiration is temporarily accumulated in shoes and socks. When wearing for a long time, a considerable amount of sweat accumulates in the shoe, resulting in a bad odor, as well as becoming a hotbed of various fungi and bacterial growth. And the like.

As a means for solving such a problem, Japanese Unexamined Patent Application Publication No. 2001-88850 discloses a refrigerator having a front compressing unit having a cooling device built in an inner bottom of a shoe and capable of compressing a refrigerant at a front side thereof, A rear expansion unit connected to the rear evaporator, and a rear compression unit connected to the rear evaporator, wherein the rear expansion unit compresses the refrigerant discharged from the rear compression unit, A second expansion valve that allows the refrigerant compressed from the compression section to expand; a front evaporator that takes ambient heat by the refrigerant expanded from the second expansion valve; And a cooling system for moving the cooling system.

Another technology is disclosed in Japanese Patent Laid-Open No. 2006-97078, in which a fine pipe filled with a coolant is buried between a sole and a middle of the shoe sole, and the pipe is connected to a small compressor built in a heel fixed to the rear of the sole And the compressor is a cooling system for lowering the shoe temperature by absorbing the heat inside the shoe while circulating the pipe in a vaporized state in a state where the refrigerant is compressed to a certain pressure by the compressor driving means provided together with the heel, The pinion is fixed to a shaft protruding forward of the compressor. The pinion is engaged with a rack formed in an operating arm that enters and exits a socket integrally provided in a case covering an outer side of the shaft. The lower part of the arm is exposed to the lower part of the heel, And the operating arm is moved into and out of the socket by an interposed spring to operate the compressor.

However, the above-mentioned patented technologies have a complex structure for forcibly circulating refrigerant in a shoe structure of a small article to be worn by a person, and expensive manufacturing costs are used for such facilities, A new cabinet system capable of providing a comfortable feeling by cooling the foot of a shoe wearer has been demanded and Korean Patent Publication No. 070733 (Apr. 13, 2007) discloses a sustained release bonding film which does not allow liquid to pass but allows gas to pass therethrough So, we tried to find a way to apply it to the shoe structure.

The present invention is conceived in view of the above-mentioned problems of the conventional shoes, and it is an object of the present invention to provide a shoe sole which can incorporate a fluid container in a floor window constituting a bottom surface of a shoe and fill a fluid container with refrigerant or a heating medium, So as to provide a functional shoe.

In addition, the fluid container installed in the shoe sole of the present invention has the object of providing a method of using shoes in which the refrigerant is filled in the summer season and the warm medium is filled in the winter season to obtain warmth.

As a means for solving the above problems, the present invention provides a shoe structure in which a fluid container filled with a refrigerant or a heating medium is contained in a midsole between a sole and a bottom tension constituting the bottom of the shoe, and a refrigerant or a heating medium is injected into the fluid container As a shoe wearer moves for a walk, the coolant or heat medium is naturally compressed by body weight and body temperature, and the cool air is sprayed or the warm air is sprayed, and the shoe can be provided as a cooling / heating system.

More specifically, the shoe to which the technical idea of the present application is applied is a functional shoe provided to accommodate a refrigerant container in a floor window constituting a floor surface and to fill a container with a heating medium such as refrigerant or hot water to adjust the internal temperature of the shoe. Wherein the bottom of the midsole and the bottom tension are formed by the outsole, the recess and the bottom of the midsole, and the midsole and the front portion of the midsole form a moving path of cold / hot heat. The bottom tube has a structure in which a hole through which cold or heat is transmitted is formed at a plurality of locations. The fluid container has an injection part at the rear side, a gas discharge port at the upper part and the front side of the fluid container, Type bonding film is attached to the substrate so that the substrate has gas permeability and does not allow the liquid to pass therethrough, And the cold / hot heat is applied to the foot of the wearer through the wearer's body and the weight of the wearer through the wear-resistant film and the gas outlet, so that coolness or warmth is applied to the foot of the wearer.

In the functional shoe of the present invention, the refrigerant injected into the fluid container should not be used because the refrigerant such as sulfur dioxide, ammonia, or methyl chloride may cause a danger even if a slight leakage occurs, and the boiling point is in the range of -40 to 0 ° C CFC compounds and liquefied gas such as LPG and LNG, which are not toxic, can also be used. However, in the present invention, when the temperature of the human body and the body weight of 10 kg or more are transferred, the refrigerant is slowly vaporized and vaporized. It is preferable to use a refrigerant which is mixed at a mixing ratio of 9 to 6: 1 to 4 in a volume ratio of -10 to -30 DEG C. As a result, even if ethyl alcohol or propylene glycol is in contact with the human body, And the mixed refrigerant is filled in the fluid container of the present invention, Because there is no harm.

Accordingly, the present invention provides a method of using a shoe for providing a cooler or a warmer to a wearer by embedding a fluid container in a bottom window constituting a bottom surface of the shoe,

Wherein a floor window of the shoe is made of an outsole, a midsole, and a bottom tension, and a concave groove portion in which a fluid container is built in a heel portion of the midsole between the outsole and the bottom tension is formed, a cold or hot heat transfer passage is formed at the center and front portion of the midsole, The bottom tube has a structure in which a hole through which cold or heat is transmitted is formed at a plurality of locations. The fluid container has an injection part at the rear side, a gas outlet at the top and front sides of the fluid container, When the footstep of the wearer moves, the cold air or warmth is ejected by a small amount through the escape film and the gas outlet by the pressure of the body temperature and the weight, Use of shoes comprising a configuration that delivers coolness or warmth It can be applied to.

The fluid container of the shoe provided in the present invention is made of a stainless steel material or an alloy material containing tin and is adapted to be installed on the upper and the front side walls of the fluid container with an inlet through which the refrigerant or the heating medium is injected and an outlet through which the refrigerant or the heating medium is slowly ejected.
