Description

Protective suit with cooling channel

The present invention relates to a protective clothing in which cold air is effectively supplied to the protective clothing that is worn for dustproofing or protective purposes during work, thereby improving the convenience of a worker.

Protective clothing is a special clothing that is worn to protect the worker from harmful surrounding environments or to prevent contamination of the working environment by dust or hair falling from the clothes worn by the worker.

Various types of protective clothing have been developed according to the purpose of use. As one of them, a protective clothing for protecting workers from toxic substances includes a top and a bottom, and the top may further include a hood covering the user's back neck, ears, and head.

Protective clothing to protect workers from harmful substances is made of air-tight fabric. The body temperature of the worker rises rapidly because the protective clothing blocks the dissipation of body temperature. Furthermore, there are cases in which the temperature of the workplace exceeds 40° C. in a semiconductor factory or a chemical factory, so that the physical strength of a worker wearing a protective suit is greatly deteriorated.

In order to solve this problem, in the prior art, a cooling vest worn in a protective clothing is presented to the worker. The cooling vest has a built-in pipe for circulating the refrigerant provided from the refrigerant supply device, and is manufactured to keep the temperature of the cooling vest cool.

Such a cooling vest is effective in lowering the body temperature of a worker, but it has a significant drawback because it contains piping materials arranged in zigzag. In other words, a heavy cooling vest adversely affects the waist and knees of a worker who works while standing.

In addition, there is a problem in that the cooling vest is caught on the body part or the work table when taking various postures according to the work method in charge of the worker, causing discomfort. For example, when you bow your hand out to take out a work piece over the reaction tank, the cooling vest gets caught in the chin of the reaction tank and you have to pull the cooling vest each time.

In addition, the cooling vest has a disadvantage of poor fit because it is thick and stiff as the pipe is provided inside.

Due to these inconveniences, some workers enter the workplace without wearing a cooling vest.

An object of the present invention is to provide a protective clothing capable of providing cool air to an operator without the inconvenience of wearing.

In addition, detailed objects of the present invention will be clearly understood and understood by experts or researchers in this technical field through the detailed contents described below.

In order to solve the above problems, the present invention is an embodiment, in the protective clothing additionally worn by the operator, the protective clothing is padded on the inner side of the protective clothing, and the edge circumference is attached to the inner surface to form a cold air channel through which cold air passes. And a flexible strip-shaped backing member that penetrates the protective clothing and extends to the outside, and includes a cold air injection member connected to the cold air channel, and a discharge portion is formed in the backing member to provide the worker with cold air entering the cold air channel. We present a protective clothing equipped with a cold air channel characterized in that it is discharged.

In the first embodiment, the backing member is disposed vertically on the back of the protective suit corresponding to the spine of the worker, and the discharge part is a first hole facing the nape of the worker, a second hole facing the back of the worker, It may include at least one of a third hole toward the center of the back and a fourth hole toward the lower back of the worker. In the first embodiment, in a basic form in which the characteristics of the invention are revealed, cold air is supplied to an operator through a cold air channel to reduce body temperature.

In a second embodiment, the backing member includes a first member disposed vertically on the back of the protective suit corresponding to the spine of the worker, and extends from the upper left and right sides of the first member along the lower shoulder of the worker, A second member having a fifth hole for discharging cold air toward the operator's armpit is formed at the end portion, extending from the lower left and right sides of the first member toward the operator’s side, and a sixth hole at the end portion for discharging cold air. It may include at least one of the formed third member and the fourth member extending from the left and right of the bottom of the first member toward a lower portion of the operator's buttocks, and having a seventh hole for discharging cool air at an end portion thereof. The form of the second embodiment is one of the forms in which the concept of the present invention is further expanded, and cold air can be provided to the worker at various locations.

In a third embodiment, the backing member is a first member that is elongated up and down on the back of the protective clothing corresponding to the spine of the worker, extends from the lower left and right of the first member toward the side of the worker, and extends from the lower left and right of the first member to the side of the worker. A fifth member with an eighth hole for discharging cold air toward and from the fifth member extends downward along the side of the lower body of the worker, and a ninth hole for discharging cool air toward the buttocks, thighs, or knees of the worker is formed. It may include a sixth member.

In a fourth embodiment, the backing member is a seventh member disposed horizontally along the waist circumference of a worker, an eighth member connected to an upper portion of the seventh member 117, and a horizontal direction from the upper portion of the eighth member. It includes a ninth member having a thirteenth hole for discharging cold air toward the nape of the worker's neck, and some sections of the sewing line attaching the seventh to ninth members to the protective clothing constitute the protective clothing. It may overlap with the sewing lines of the fabric patterns that are made.

For these embodiments, the edge of the backing member is attached to the protective clothing by sewing, and a protective coating may be additionally formed on the portion where the sewing is performed. This is to further increase the safety of workers by preventing the penetration of harmful substances.

In addition, a wrinkle may be formed around an edge of the coupling hole of the protective suit to which the cold air injection member is attached. By allowing the cold air to flow smoothly through the portion where the cold air injection member and the cold air channel are connected, it helps to smoothly enter the cold air into the protective clothing.

As another example of the cold air injection member, it may include a gripper coupled to the front and rear of the coupling hole penetrating the protective suit, and a one-touch fitting member connected to the gripper and gripping a tube providing cool air.

In addition, the protective clothing is provided with a check valve for discharging the air inside the protective clothing to the outside, so that the air inside the protective clothing is discharged to the outside, so that cold air can be continuously introduced into the protective clothing.

According to an embodiment of the present invention, by forming a cold air channel through the backing member inside the protective clothing, a passage for moving cold air into the protective clothing is secured, and by discharging the cold air to a specific body part where the worker feels cool, in a hot work environment. It can improve the working environment by giving workers a refreshing feeling. Accordingly, it is possible to solve various problems of the conventional technology by replacing the cooling vest according to the conventional technology.

The protective clothing according to the present invention can be produced in large quantities at an inexpensive price, so it is sufficient for disposable use in a workplace where harmful substances are present. In addition, the weight of the protective clothing provided with the backing member is only slightly increased so that the operator cannot feel it compared to the weight of the original protective clothing, and there are no major restrictions on folding or wrinkles of the protective clothing, so that the operator can wear it comfortably.

Hereinafter, the configuration, function, and operation of the protective clothing having a cold air channel according to the present invention will be described with reference to the accompanying drawings. However, reference numerals for the same or similar components throughout the drawings and embodiments will be used in a unified manner.

In addition, in the following description, terms such as'first' and'second' are used to distinguish constituent elements whose technical meaning is within the same range for convenience. That is, any one configuration may be arbitrarily named as'first configuration' or'second configuration'.

The accompanying drawings show an applied embodiment of the present invention, and the technical idea of the present invention should not be limitedly interpreted through the accompanying drawings. If it can be construed that some or all of the figures are not necessarily required for the implementation of the invention, from the perspective of an expert belonging to this technical field, this does not limit the invention described in the claims.

1 to 4 are related to the protective clothing according to the first embodiment of the present invention.

The protective clothing 100 according to an embodiment of the present invention is manufactured as a single layer using a non-woven fabric or a waterproof cloth material, and is additionally worn by a worker who wears casual clothes. The upper portion 104 and the lower portion 105 are integrally manufactured, and the upper portion 104 is provided with a hood 106 that covers the operator's head. In other embodiments not shown, the hood may be omitted, and only in the first embodiment, the lower portion may be omitted.

The backing member 10 is used to form a cold air channel S through which cold air passes inside the protective suit 100. The backing member 10 may be a flexible fabric or a thin synthetic resin sheet. In general, the same material as the fabric material of the protective clothing can be used.

In the first embodiment, the shape of the backing member 10 is a long strip shape having a constant width. The backing member 10 is affixed face-to-face on the inner surface of the protective clothing 100, and the position is fixed in such a manner that the edge circumference 11 is attached to the inner surface of the protective clothing 100.

At this time, the attachment of the backing member 10 may be made by sewing, which means that the backing member can be attached during the process of making the protective clothing into sewing. As another example, an adhesive or double-sided tape may be used for the attachment of the backing member.

Referring to Figure 3, the cold air channel (S) is formed between the protective clothing material 101 and the backing member (10). In order to secure the cross section of the cold air channel to an appropriate size, the edge of the backing member may be attached to the inner side of the protective suit while the center of the backing member is stiffly closed.

Since the backing member 10 or the protective clothing material 101 has sufficient flexibility, even if the backing member 10 and the protective clothing material 101 are overlapped face-to-face, the cold air channel swells up by the injected cold air. Space can be secured to flow.

On the other hand, when the backing member 10 is attached to the protective clothing by sewing, a hole through which the thread passes is formed. Since there is a risk that harmful substances may infiltrate into the protective clothing through these holes, a protective coating 12 may be additionally formed in the sewing part. Here, the protective coating 12 is a known polymer-based coating agent, and may be subjected to dustproof treatment by overcoating or spraying the sewn portion.

Meanwhile, referring to FIG. 2, the cold air injection member 30 penetrates the protective suit 100 in a cylindrical shape and extends to the outside.

The cold air injection member 30 may also be made of the same material as the protective clothing material. The cold air injection member 30 is a portion connected to the tube plug 32 of the cold air supply means 31 for providing cold air.

Here, since the structure or operation method of the cold air supply means 31 and the tube plug 32 is the same as known, a detailed description thereof will be omitted. However, the cold air supply means is not necessarily limited to providing cold air. Room temperature air may be provided according to the working environment in which the protective clothing is used, and even warm air may be provided if the working environment is cold enough.

The cold air injection member 30 is attached to the center of the cold air channel S through a coupling hole 102 penetrating the protective suit 100. At this time, in forming the coupling hole 102, the protective clothing material is creased to form a wrinkle 103 around the edge of the coupling hole 102. By attaching the cold air injection member 30 to the coupling hole 102 where the wrinkle 103 is formed by sewing or bonding, the wrinkle 103 of the coupling hole 102 is maintained.

The corrugation 103 at the periphery of the coupling hole 102 forms a certain amount of internal space at the connection portion with the cold air injection member 30, and allows the incoming cold air to smoothly enter the cold air channel S. .

Conversely, when the wrinkles are not formed, there is a concern that the inflow of cold air may not be smooth as the coupling hole and the connecting portion of the cold air injection member are folded due to the weight of the tube plug connected to the cold air injection member. This is a problem that may occur mainly when the cold air injection member is made of a fabric material having high flexibility, such as a protective clothing material. However, when the corrugation 103 is formed in the periphery of the coupling hole 102, as the cold air enters the cold air channel (S) through the valleys between the corrugations, the cold air injection member that was bent as the flow rate increases gradually. As a result, smooth inflow of cold air becomes possible.

The protective coating 12 may also be applied to the connection portion between the cold air injection member 30 and the coupling hole.

13 shows another embodiment of the cold air injection member 30.

In the illustrated embodiment, the cold air injection member 30 includes a gripping hole 33 and a one-touch fitting member 34.

The gripping tool 33 is a member that is engaged with each other while being opposed to each other before and after the coupling hole, and is for firmly fixing the one-touch fitting member 34. The gripping hole 33 includes a pair of coupling members that are coupled to each other while facing each other on the front and rear surfaces of the coupling hole, and a cold air hole 331 is formed in the center thereof.

The one-touch fitting member 34 is a cylindrical casing 341, a gripping arm 342 protruding toward the center of the inner diameter of the casing 341 by biting or releasing the fixing of the tube T providing cold air, The locking ring 343 supporting the deformation of the gripping arm 342, the operating rim 344 protruding forward of the casing 341, and the end inserted into the casing 341 contacting the gripping arm 342 , A locking ring 343 and a gripping arm 342, and a guide part 345 for guiding the back and forth movement of the operating rim part 344.

Such a one-touch fitting member 34 holds the outer circumferential surface of the inserted tube T with the gripping arm 342 so that the tube does not come off during work, and after the work is finished, the gripping arm is simply pressed by pressing the operating rim 344. It is to allow the tube (T) to be easily separated by opening the 342 widely. This one-touch fitting member 34 has the advantage of allowing the operator to easily couple or separate the tube by itself as the cold air injection member 30 is located behind the waist of the protective suit.

This one-touch fitting member can be changed to any one of a variety of known clamping means for fixing or releasing the tube.

The backing member 10 is provided with at least one discharge part 20 through which the cold air that has entered the cold air channel S is discharged to the worker. In the embodiment of the present invention, the discharge part 20 is shown as at least one hole, but the shape of the hole may be variously changed to an oval, a square, etc. in addition to a circular shape, and a mesh, a cloth for obstructing the direction, etc. May be.

In the backing member according to the first embodiment, the discharge portion 20 includes first to fourth holes 21 to 24. These first to fourth holes 21 to 24 may be changed in various combinations in other embodiments. For example, only the first hole 21 may be formed alone, the first hole 21 and the second hole 22 may be formed, and the third and fourth holes may be omitted. That is, in another embodiment, at least one or more of the first to fourth holes may be included.

The first hole faces the nape of the worker, and when considering the worker wearing a normal top, the cold air is discharged to the nape of the neck that is not covered by the top. As a result of repeated experiments, it was confirmed that the part where the worker feels the most cold air is the nape of the neck. Since wearing protective clothing while wearing casual clothes, the area where the skin is directly exposed to the cold is near the nape of the neck, and the area where the cold is felt with a low flow rate when feeling the heat is also near the nape of the neck.

Furthermore, the air discharged to the first hole 21 is discharged between the facial skin and the hood after filling the protective clothing. This flow of air also functions to more safely protect workers from harmful substances by preventing external harmful substances from entering the protective clothing 100 through the gap between the face and the hood.

The second hole 22 is formed at a position lower than the first hole 21 so as to face the back, which is between the shoulders. The rear nape discharges cold air near the worker's neck bone so that the cold air can reach the area where the worker feels cool for the second time. When used together with the first hole 21, cold air is actively supplied to the back neck and its periphery, thereby contributing to significantly lowering the perceived temperature of the worker.

The third hole 23 and the fourth hole 24 are formed in a position spaced apart from the second hole 22 in order. The third hole 23 discharges cold air toward the center of the operator's back, and the fourth hole 24 discharges the cool air toward the lower back of the operator. The third hole 23 and the fourth hole 24 supply cold air to the operator's back and its periphery, thereby lowering the overall sensory temperature.

Referring to Figure 4, the protective clothing is provided with a check valve 50 for discharging the air inside to the outside. The check valve 50 is opened as the pressure inside the protective clothing increases according to the continuous supply of cold air, and blows the air in the protective clothing to the outside, but prevents external air from flowing into the protective clothing. As the check valve 50 is provided, air in the protective clothing is more smoothly discharged to the outside, and new cold air can be smoothly introduced into the protective clothing.

Specifically, the check valve 50 is installed in the protective clothing, the case portion 51 forming the open passage 511, the passage 511 by the flow of air blown from the inside of the passage 511 is blocked normally. It includes a soft elastic sheet 52 to open the ). Further, a blocking member 53 that forms an air passage downward while covering the check valve 50 is provided, so that the check valve 50 can be prevented from being exposed to the outside.

In consideration of the case where the pressure of the injected cold air is somewhat small, the check valve 50 may be provided on the forearm of the protective suit.

If the check valve is mounted on the body part such as the back or side and the injection pressure of cold air is small, there is a concern that the air pressure inside the body part may not be formed large enough to deform the elastic seat of the check valve. In this case, due to the internal pressure of the protective clothing, cold air no longer flows in, and the internal temperature gradually rises.

Even if the injection pressure of cold air is low in this way, when the check valve 50 is installed in the forearm, the volume change of the arm part is large and quickly occurs when the operator holds the arm and bends the arm. This greatly increases and the check valve opens, allowing the air inside the hazmat to escape to the outside.

5 to 6 are related to the protective clothing according to the second embodiment of the present invention. The protective suit 100 according to the second embodiment is provided with a backing member 10 and a cold air injection member 30, and includes the features of the first embodiment as described above within a range not inconsistent with the contents described below. can do.

The backing member 10 employed in the protective clothing 100 according to the second embodiment includes a first member 111, a second member 112, a third member 113, and a fourth member 114.

In another embodiment not shown, one or more of the second member 112, the third member 113, or the fourth member 114 may be omitted. In other words, based on the first member 111, at least one of the second member 112, the third member 113, and the fourth member 114 may be added thereto. Whether or not some of the second member 112 to the fourth member 114 are omitted may be determined based on a pressure condition of supplied cold air and a working environment.

Hereinafter, a description will be made based on an embodiment of the drawings in which all of the first member 111 to the fourth member 114 are provided.

The first member 111 is disposed vertically on the back of the protective clothing corresponding to the spine of the worker, and is substantially the same as the shape of the backing member according to the first embodiment.

A first hole 21, a second hole 22, and a fourth hole 24 are formed in the first member 111 from above along the length direction. The first hole 21 corresponds to the position of the operator's nape, and the second hole 22 and the fourth hole 24 correspond to the position of the operator's rear nape and lower back. The cooling effect according to the positions of the first hole 21, the second hole 22, and the fourth hole 24 is the same as the first hole, the second hole, and the fourth hole of the first embodiment described above. In another embodiment, the second hole 22 or the fourth hole 24 of the first member 111 may be omitted.

The second member 112 to the fourth member 114 take a branch shape extending from the first member 111. The second member 112 to the fourth member 114 are also attached to the inner side of the protective suit along the edge, so an inner channel is formed, and the cold air channel inside the first member 111 is the second member 112 to the fourth member. It is connected to each internal channel inside of (114). Accordingly, the cold air that has entered through the cold air injection member 30 located in the center of the first member 111 is moved to the second member 112 to the fourth member 114 through the first member 111.

In addition, the second member 112 to the fourth member 114 are symmetrical with respect to the first member 111.

The second member 112 is a portion extending to the upper left and the right side of the first member 111, respectively, and a fifth hole 25 is formed at an end portion thereof.

The second member 112 is positioned lower than the shoulder line of the worker wearing the protective clothing, and the fifth hole 25 discharges cold air toward the operator's armpit. Usually, protective clothing is made in a free size with a generous size for anyone to wear, and when a worker with a general physique wears it, a large empty space is formed under the armpit. The fifth hole 25 discharges cold air into this empty space so that the worker can easily feel the cold air.

The third member 113 extends left and right from the first member 111 at the height of the operator's side. A sixth hole 26 is positioned at the end of the third member 113 to discharge cold air to the side of the worker.

At this time, by sufficiently lengthening the horizontal length of the third member 113, the third member 113 is also bent along the waist circumference of the protective clothing, so that the end of the third member 113 reaches the side of the operator. Accordingly, the sixth holes 26 formed at the ends of the third member 113 are located on the left and right sides of the operator's waist, so that cold air is discharged from both sides of the waist. As a result, it is possible to feel cold on both sides of the operator's waist away from the back.

Meanwhile, the fourth member 114 extends obliquely to the left and right from the bottom of the first member 111 and extends to the lower portion of the operator's hip. The seventh hole 27 provided at the end of the fourth member 114 discharges cold air to a lower portion of the hip where the hip and the thigh meet.

When considering a standing worker, it is possible to cool off the heat by supplying cold air under the buttocks, which is an area where sweat is easily occupied.

7 and 8 are related to the protective clothing according to the third embodiment of the present invention. The protective clothing 100 according to the third embodiment is provided with a backing member 10 and a cold air injection member 30, and the first embodiment or the second implementation described above within the scope not inconsistent with the contents described below. The characteristics of the example may be included as it is.

The backing member 10 employed in the protective clothing 100 according to the third embodiment includes a first member 111, a fifth member 115 and a sixth member 116.

The first member 111 is disposed vertically on the back of the protective suit 100 to correspond to the spine of the worker, and has substantially the same shape as the backing member of the first embodiment described above. A first hole 21 for discharging cold air to the nape of a worker's neck is formed in the upper part of the first member 111.

The fifth member 115 is elongated from the lower end of the first member 111 to the left and right, and its shape is substantially the same as that of the third member of the second embodiment. The fifth member is formed with an eighth hole 28 for discharging cold air toward the side of the worker.

However, in the illustrated embodiment, each of the eighth holes 28 is formed in a pair. To distinguish this, the hole located far from the first member 111 will be referred to as the 8-1 hole 28a, and the remaining holes will be referred to as the 8-2 hole 28b.

The 8-1 hole 28a faces the front side of the worker's side, and the 8-2 hole 28b discharges cold air toward the rear side of the side. As cold air is discharged from a pair of holes arranged along the front and rear sides of the side, the discharged air moves to the front and back of the operator's waist. Therefore, the cool feeling that started from the side continues behind the abdomen and waist, and the entire waist circumference feels cool.

Although not shown, either of the 8-1 hole 28a or the 8-2 hole 28b may be omitted.

Meanwhile, the sixth member 116 extends below the fifth member 115 from the operator's side position, and is placed along the operator's lower body side. A ninth hole 29 for discharging cold air is formed in the sixth member 116, and the ninth hole 29 may be formed at a position facing the operator's hips, thighs, or knees. In the drawing, it is shown that three ninth holes 29 are formed, but one or two holes may be omitted in other embodiments.

According to the contents shown in FIGS. 7 to 8, the cold air discharged into each of the ninth holes 29 flows back along the operator's legs and moves behind the hips, the thighs, or the knees.

The sixth member 116 extends downward along the operator's side line, so that even if the operator frequently bends his leg, cold air can be discharged into the ninth hole 29 without clogging.

9 and 10 are related to the protective clothing according to the fourth embodiment of the present invention. The protective clothing 100 according to the fourth embodiment is provided with a backing member 10 and a cold air injection member 30, and the first to third embodiments described above within the scope not inconsistent with the content described below. The characteristics of the example may be included as it is.

The backing member 10 according to the fourth embodiment includes a seventh member 117, an eighth member 118, and a ninth member 119. As an optional additional configuration, a tenth member 120 extending below the seventh member 117 is further included.

The seventh member 117 is disposed horizontally along the operator's waist circumference, and extends to the lower abdomen by passing both sides around the operator's waist.

The eighth member 118 is connected to the top of the seventh member 117 to extend the cooling channel, and the ninth member 119 is connected in the horizontal direction from the upper end of the eighth member 118 of the operator, near the nape of the operator's neck. It forms a cooling channel passing through. As the cooling channel formed by the ninth member 119 is connected to the cooling channel of the eighth member 118, the cooling channels of the seventh member 117 to the ninth member 119 are connected to one.

Furthermore, a pair of tenth members 120 are connected to a lower portion of the seventh member 117. The tenth member 120 has a shape connected to the eighth member 118 vertically. The cold air channel formed by the tenth member 120 is also connected to the cold air channel of the seventh member 117.

In the illustrated embodiment, the seventh member 117, the pair of the eighth member 118, and the ninth member 119 have a square shape, but in other embodiments, the left and right eighth members may be omitted. Also, the tenth member may be omitted.

Further, some sections of the sewing lines for attaching the seventh member 117 to the ninth member 119 to the protective clothing overlap with the sewing lines of the fabric patterns constituting the protective clothing.

Referring to FIG. 10, the protective clothing is formed by sewing the first and second fabric patterns 107a and 107b, which form the upper part, and the third and fourth fabric patterns 107c and 107d, which form the lower part. .

The first and second fabric patterns 107a and 107b and the third and fourth fabric patterns 107c and 107d are arranged to be symmetrical, respectively. The first and second fabric patterns 107a and 107b form the back and the chest while forming from the neck circumference to the shoulders and the upper arms, and the third and fourth fabric patterns 107c and 107d are from the circumference of the abdomen to the hips and the knees. Form up to the site.

These fabric patterns 107a, 107b, 107c, and 107d are connected by sewing, in which case the sewing line L1 of the upper edge of the seventh member 117 and the sewing line of some of the edges of the eighth member 118 The backing member may be disposed so that some of the upper edges of the (L2) and the ninth member 119 overlap with the sewing lines of the fabric patterns.

Accordingly, it is possible to minimize the occurrence of needle holes in the impermeable protective clothing material due to sewing operations, and to minimize the protective coating treatment performed along each sewing line. Accordingly, the cost of protective clothing can be reduced, and the needle hole itself for harmful substances to enter is also reduced, further improving the safety of workers.

The cold air injection member 30 is connected to the middle of the seventh member 117, and the injected cold air moves to the left and right of the seventh member 117 along the formed cold air channel. Tenth holes 40 for discharging cold air toward the lower abdomen of the worker are formed at both ends of the seventh member 117. Furthermore, the seventh member 117 is further formed with an eleventh hole 41 for discharging cold air toward the rear side of the operator's side. In another embodiment, the eleventh hole 41 may be omitted.

The tenth hole 40 and the eleventh hole 41 may cool both the front and rear surfaces of the worker by discharging cold air around the waist of the worker.

The eighth member 118 is formed with a twelfth hole 42 for discharging cold air corresponding to the height just below the operator's armpit.

Meanwhile, a thirteenth hole 43 for discharging cold air is formed in the ninth member 119 at a position corresponding to the nape of the operator's neck. In the illustrated embodiment, since a pair of thirteenth holes 43 are formed, a large amount of cold air can be sent to the worker. In another embodiment, one thirteenth hole may be formed.

A pair of fourteenth holes 44 are formed in the tenth member 120. Like the ninth hole of the third embodiment, the fourteenth hole 44 can supply cold air to the lower body of the operator.

The number of the tenth hole 40 to the fourteenth hole 44 may be changed or the arrangement position thereof may be changed in other embodiments.

<Experimental Example>

Article-An experiment was conducted to confirm the cooling performance of the protective clothing provided with the backing member according to the embodiment. In an indoor space where the indoor temperature gradually changes from 29°C to 26°C, the temperature change of the protective clothing when cold air is injected while wearing the protective clothing according to the embodiment, and the temperature change of the protective clothing in the state of wearing the existing protective clothing were measured at intervals of 4 minutes. , The injected cold air is 24±3℃. The time when cold air was injected into the protective suit was 4 minutes after the start of the experiment. The same subjects were targeted, and measurements were taken by alternating three times for each protective suit.

Table 1 below is an average of the temperature of the protective clothing measured at 4 minute intervals. The temperature of the protective clothing was measured by photographing the rear view of the worker with a thermal imaging camera.

Time (minutes)
Existing protective clothing temperature (℃)
Protective clothing temperature according to the present invention (℃) 0 29.0 28.5 4 29.7 23.8 8 31.0 25.0 12 31.2 25.2 16 31.5 24.4 20 31.8 25.0

It is confirmed that the existing protective clothing gradually increases in temperature due to body temperature over time. On the other hand, it was confirmed that the protective clothing according to the embodiment of the present invention was kept low at approximately 25°C after 4 minutes of injection of cold air.

Referring to FIG. 11, it can be seen that the cooling channel is spread to the surrounding area as well as the portion where the cooling channel is formed, which is interpreted to mean that the cold air sprayed from the discharge port fills the space between the protective clothing (backing member) and the worker.

The protective clothing according to an embodiment of the present invention forms a cold air channel through which cold air moves by attaching a backing member, and effectively lowers the body temperature of a worker working in a hot work environment by discharging cold air to a specific area including the nape of the worker's neck. To be able to. Therefore, it is possible to give the operator a cool feeling even without wearing a cooling vest according to the prior art.

The backing member can be made of the same material as the protective clothing, or a sheet that is lighter than that, and the protective clothing is still very light and easy to bend. Therefore, it is possible to move in various ways while wearing protective clothing, and there is no inconvenience that the protective clothing hangs all over the place.

The protective clothing provided with the backing member can be produced in large quantities at an inexpensive price because the cost increase is not large, and it is suitable for the protective clothing used for single use.
