Cooling device for insulated vest {COOLING APPARATUS FOR COOL VEST}

The present invention relates to a cooling device for an insulated vest, and in particular, so that it can be applied to outdoor workers in summer or patients who have difficulty controlling body temperature, the cooling time of the vest can be maintained for a long time by using the cold air of dry ice and cooling water, and the cooling water is dry. It relates to a cooling device for an insulated vest with an improved structure so that the cooling temperature of the vest body can be controlled by using the cold air generated from the dry ice as well as not to be frozen by the cold air of the ice.

In general, a vest is a term that refers to a sleeveless upper garment, and in the US, Vest, in the UK, a waist coat, and in France, a gilet is a term corresponding to a vest.

In men's wear, these vests are usually worn under a waist-length or slightly longer outerwear, and in women's wear, they have been worn under outerwear or applied as outerwear itself. It is also used as a fashion item to match, and has been used as a functional aspect to hold various things because it has many pockets, and also as an aspect to complement the flaws of the body.

In addition to the functional aspect of the above-mentioned vest, the use of a cooling vest used for overcoming a cold or hot environment or for creating a cool environment in recent years is rapidly increasing. An example of a cooling vest that has been developed for this purpose is composed of a structure in which a refrigerant pack pocket for accommodating a refrigerant pack (not shown) composed of a special refrigerant, etc. has been

With this configuration, when the wearer wears the cooling vest with the refrigerant pack installed in the refrigerant pack pocket, the cooling vest causes a phase change in which all the refrigerant in the refrigerant pack is in a liquid (or gel) state at room temperature. As it delivers cool air to the wearer until the end of the day, it can maintain a cool state for a relatively long time, so it can be usefully used for users who need to work continuously in a hot environment or users who need to lower body heat for various purposes such as medical care. .

However, in order to efficiently transfer the cold air from the cooling vest described above, it is preferable that the side of the cooling vest to which the refrigerant pack pocket is coupled is in close contact with the wearer's body. Since the refrigerant pack pocket is only combined on the inner side, it was impossible to manufacture and provide a cooling vest that can be closely attached to the body of all users according to the various body sizes of various wearers with such a structure.

As a prior art related to the existing cooling vest, as disclosed in Korean Utility Model Publication No. 20-0424919 "Adhesive cooling vest" (registration date: August 22, 2006), when worn, it wraps around the wearer's front such as abdomen and chest. At least two or more elastic bands each having both ends connected to both side edges of the front plate and the rear plate so as to be positioned on both sides of the front plate, the rear plate covering the back of the wearer's back, and the wearer's side parts; , Velcro cloth coupled to each surface of the extended portion of the front plate and the rear plate that wraps around the wearer's shoulder to enable detachment of the abutting surfaces of the two separated parts, and the front plate and/or the It is configured to include at least one refrigerant pack pocket fixedly coupled to the surface of the back plate, so that the entire inner surface of the vest is evenly adhered to the entire user's upper body, so that the cooling effect is further improved compared to the conventional cooling vest. .

As a prior art in which dry ice is applied to the existing cooling vest, as disclosed in Korean Utility Model Publication No. 20-1995-24243 "Multipurpose Vest for Human Protection" (published on September 13, 1995), It was made with a zip-inserted type by making quarters and embedding suture pockets depending on the purpose. Dry ice was put in during high-temperature work to block the heat, and in winter, a warming bag was put in to be used as a winter clothing.

However, the existing cooling vest functions to protect the vest wearer from the sweltering heat of summer, but most of them use ice or refrigerant ice packs frozen in the refrigerator. In the case of performing outdoor work in weather, there is a limitation, and there is no function to control the cooling temperature, which causes inconvenience to the user.

Korean Utility Model Publication No. 20-0424919 "Adhesive Cooling Vest" (Registration Date: 2006.08.22) Korean Utility Model Publication No. 20-1995-24243 "Multipurpose vest for human body protection" (published date: September 13, 1995)
