Description

Cold air supply system of welding work clothes and welding mask using mobile air conditioner

The present invention relates to a cold air supply system of a welding work clothes and a welding mask using a mobile air conditioner, in particular, by supplying the fresh cold air generated in the mobile air conditioner to the welding work clothes to cool the heat generated in the body of the worker The present invention relates to a cold air supply system for welding work clothes and a welding mask using a mobile air conditioner that can suppress harmful gas generated during welding.

In general, when welding using a welding rod covered with a coating material such as arc welding, arc flash, harmful gas, electromagnetic waves harmful to human body, and high temperature heat are generated. In order to protect the worker from such harmful elements, the worker must wear protective clothing such as welding mask and welding glove, which can protect the worker's face.

But. Among the protective equipment used to protect workers, welding work clothes are made of a thick layer of heat-resistant material to protect the worker from the heat generated during welding, and lead which can block electromagnetic waves harmful to the human body. It is formed by inserting and sewing so that the weight is heavy and the outside air is not distributed to the inside. When the worker wears the welding work clothes formed as described above and the worker performs the work, the heat generated from the body is not released to the outside, and the worker sweats a lot. Therefore, there is a problem that the work efficiency is lowered and the welding failure rate is increased.

In addition, among the protective equipment used to protect the worker, the welding mask is configured to protect the worker from arc flash and harmful gas generated during welding, or is configured to protect the worker from only the arc flash. However, the welding mask configured to protect the worker from arc flash and harmful gas generated during welding is composed of a safety glasses that can perform work while protecting the eyes, and an inlet that can inhale and discharge air. Other parts are designed to seal most of the human head. The welding mask configured as described above is filtered to some extent by the filter disposed at the suction port, but the degree of filtration is very insufficient. When the worker inhales the unfiltered harmful gas during work, it causes gas poisoning, respiratory disorder, and vision disorder due to harmful gas. In addition, since most of the human head is sealed, there is a problem in that the air flow is not smooth and the heat generated from the body is not discharged to the outside, so that the worker performs a lot of sweating. In addition, when the work is performed in a narrow space, there is a problem that industrial accidents may occur because it is not possible to supply the worker with sufficient oxygen to breathe.

As described above, when performing work on a hot day or a place where the work space is worn with a welding work clothes and a welding mask, the heat generated by the body is further increased and the working conditions are further worsened.

The present invention has been made to solve the problems as described above, for welding using a mobile air conditioner that can effectively cool the heat generated in the body during welding, as well as suppress the influx of harmful gases generated during welding. The purpose is to provide a cold air supply system for the work clothes and welding mask.
