Description

Cooling fan for cloth}

The present invention relates to a cooling fan for clothes that can cool a wearer's body by being mounted on clothes such as work clothes and blowing air therein.

Globally, the impacts and damages caused by climate change are constantly increasing, and their intensity and frequency are also increasing. IPCC (Intergovernmental Panel on Climate Change) forecasts a temperature increase of 3.7℃ by 2100 due to an increase in the concentration of greenhouse gases (based on RCP 8.5). In addition, the Korea Meteorological Services (KMA) predicts future climate change using the IPCC's RCP (Representative Concentration Pathways) scenario. Heat wave days are predicted to increase fourfold from the current 10.1 days to 40.4 days, and the number of tropical night days to increase 14 times from the current 3.8 days to 52.1 days. These changes will affect health, agriculture, ecosystem, industry, economy, and other various fields. In particular, the impact on working conditions is expected to deteriorate the health and economic conditions of workers.

In general, when spraying pesticides to prevent pests and pests of agricultural crops in paddy fields, wear work clothes that can prevent the penetration of pesticides and perform spraying in order to prevent the spraying pesticides from directly contacting the skin.

In addition, even when carrying out street quarantine work in which quarantine drugs are sprayed using a sprayer, wear work clothes that can protect the quarantine drugs from contacting the skin exposed by the weather, such as naturally occurring wind.

However, in the case of working in the summer and in a closed space, working at various high temperatures, and performing various pest control operations, the inside of the work clothes is hot and the user's discomfort is increased due to the humid environment. There was a problem.

In particular, high humidity and low wind speed are known as factors that give a lot of heat stress to the human body during a period of high temperature, and the worker may be threatened with life due to the heat severity that may occur.

Heat severity is a phenomenon that occurs when the balance of water and salt in the body collapses due to work and exercise in a high temperature and high humidity environment, making it impossible to control body temperature. It may lead to death, so prompt treatment is required, especially for the elderly and children.

Heatstroke, heat exhaustion, and heat cramps are the types of heatstroke, and heatstroke is caused by the inability to control body temperature. Typical symptoms include an increase in body temperature, loss of consciousness, inability to talk, or collapse. Heat fatigue is caused by dehydration and is accompanied by symptoms such as boredom, dizziness, vomiting, and headache. In the case of heat cramps, when only water is consumed after sweating a lot, the salt in the blood becomes insufficient, causing cramps or muscle pain.

In order to solve the problem of such work clothes, products that can lower the body temperature of a worker by installing a fan in the work clothes and blowing air into the work clothes have been developed.

However, since the cooling fans mounted on the work clothes according to the prior art are manufactured using a general fan as a substitute, there is a problem in that cooling efficiency is reduced because a specialized operation for work clothes is not performed.
