Description

Cool comforter including refrigerant tube{COOL SHEET COMPRISING REFRIGERANT TUBE}

The present invention relates to a cool futon technology including a refrigerant tube, and more particularly, includes a refrigerant tube in which a tube filled with a refrigerant in the futon is embedded in a detachable form to enable cool and convenient use. It is about a cool comforter.

As the climate of our country is warming every year, whether it is the effect of global warming or not, there is growing concern that it is resembling a subtropical climate. Therefore, the tropical night phenomenon that appeared only in the hot summer heat is becoming more and more frequent.

Tropical night phenomenon refers to the time when the temperature does not drop even at night because the heat of the ground heated by solar heat during the day is radiated into the atmosphere during the night as a radiation phenomenon, usually when the minimum temperature in the morning exceeds 25 degrees Celsius. These tropical nights are more pronounced in large cities where the ground is almost paved and forests are relatively scarce. In particular, it gets worse on days when the air flow stops and the wind is not blowing.

Rest, especially sleep, is highly influenced by temperature and weather. As the temperature rises, the heart rate increases while sleeping, the body moves more frequently, and the depth of sleep decreases. Therefore, it does not seem to be sleeping even after sleeping, and it is not possible to recover. In addition, if the change in sleep continues, even if the tropical night disappears, it does not recover immediately.Therefore, various symptoms such as fatigue, irritability, lethargy, difficulty concentrating, headache, loss of appetite, and digestive disorders appear, resulting in decreased work efficiency and industrial accidents. The possibility of being connected increases.

Many people cool the heat by installing electronic products such as air conditioners and fans in their living spaces.

However, artificial winds from air conditioners and fans cause air conditioners in people. In addition, the use of such electronic devices for a long time places a great burden on users by charging excessive electricity bills.

Nowadays, instead of artificial wind, products that are harmless to the human body and without the burden of usage fees are in the spotlight. For example, an increasing number of people are looking for products such as cool mats that can be used coolly on a bed or on the floor in the hot summer.

Cool mat is a cooling gel that uses the properties of a phase change material (PCM), and the heat in the body is absorbed by the mat, and the cold air of the cooling gel is absorbed into the body, lowering the body temperature by 3~5℃.

Korean Patent Laid-Open Publication No. 10-2015-0108505 (2015.09.30) relates to a cool mat and its manufacturing method. A refrigerant material contained in the cool mat is impregnated into the pores of the intermediate part through a separate intermediate part. By being included in the refrigerant material from being damaged or cracked even with frequent bending or compression, durability is improved. In addition, the intermediate part impregnated with the coolant material in the cool mat improves elasticity and resilience through a separate buffer support. ·It proposes a cool mat and its manufacturing method that improves the holding power through the lower plate and maximizes the contact area between the refrigerant material and the outer skin of the cool mat, even if a separate medium is included in the cool mat.

Korean Patent Publication No. 10-1895072 (2018.08.29) relates to a functional blanket having an air fluidized bed, and an air fluidized bed in which air flows by receiving cold or hot air from an air supply unit that supplies cold or hot air.
