In this case, it is possible to prevent the user from being exposed to the risk of virus infection by introducing external air to cool the inside of the protective suit, and to cool the inside of the protective suit while circulating only the air inside the protective suit.

The heating and cooling system 1 for protective clothing is worn by a user wearing protective clothing and moved on the body. In one embodiment, it may be preferable that the heating and cooling system 1 for protective clothing can be lightened to have a weight of at least 2Kg or less. This may be to facilitate the activities of the user (the wearer of the hazmat suit) who wears the heating and cooling system 1 for the hazmat suit as described above.

Hereinafter, the technical idea of the present invention will be described in detail with reference to the drawings.

Figure 2 schematically shows the appearance of the heating and cooling system for protective clothing according to an embodiment of the present invention.

Referring to FIG. 2 , the heating and cooling system 1 for protective clothing according to an embodiment of the present invention includes a housing 100 and a connection hose that communicates with the housing 100 and allows cold air discharged from the housing 100 to pass through ( 130), and may include at least one inlet fan 300 for introducing air into the housing 100 and generating an airflow inside the housing 100.

As described above, at the end of the connecting hose 130, a connecting portion 140 capable of being coupled to a connecting holder provided in advance in the protective clothing may be formed. The connection unit 140 may be implemented in various forms, and in any form, cold air is supplied to the inside of the protective suit through the connection holder through the connection hose 130 , so that external air is not supplied mixed with cold air or warm air. It may be desirable to be able to be blocked from the outside when the connection part 140 and the connection holder are coupled. An example of implementation of such a connection unit 140 and a connection holder is shown in FIG. 3 .

3 schematically shows a connection part of a heating and cooling system for protective clothing according to an embodiment of the present invention.

Referring to FIG. 3 , a connection hose 130 is provided from the heating and cooling system 1 for protective clothing according to an embodiment of the present invention, and an end (ie, connection portion 140) of the connection hose 130 is connected to a connection holder ( 600-1) is shown to be fitted. In this case, when the connection part 140 is coupled to the connection holder 600-1, a predetermined locking protrusion (not shown) or a locking protrusion (not shown) may be formed so as not to easily escape. In addition, a predetermined locking groove (not shown) may be formed in the locking holder 600-1 so that the locking protrusion or the locking protrusion can be hooked and fixed. According to one example, after the connection part 140 is fitted to the connection holder 600-1 and rotates by a predetermined angle, the connection holder ( 600-1), it is possible to prevent the connection part 140 from being easily separated. In addition, the connection holder 600 - 1 and the connection part 140 are coupled in various ways to receive cold air (or warmth) from the heating and cooling system 1 for protective clothing, and external air may not pass through.

Depending on the embodiment, a separate small fan 330 may be provided inside the connection unit 140 or the connection hose 130 , or inside the connection holder 600 - 1 . In this case, the small fan 330 may be driven from the housing 100 to the connection holder 600-1 side (ie, the protective clothing side), and the connection hose ( 130), by making the flow of the cold air (or warm air) moving through the smoother, it is possible to facilitate the circulation of the cold air (or warm air).

Meanwhile, the housing 100 may include a thermoelectric module therein, as will be described later. As is widely known, the thermoelectric module is a cooling device or heat generating device using current through the Peltier effect, in which, when current flows through both ends, heat moves along the charge, one side is cooled by endothermic action and the other side is heated by exothermic action. used as a device.

As is widely known, a thermoelectric module utilizes the filter effect of a thermoelectric element, in which, when current flows through both ends, heat moves along the charge, cooling one side and heating the other side, a cooling device or a heating device using current can be used to make

The present invention uses the Peltier effect of such a thermoelectric module to allow a user wearing a protective suit to selectively provide cooled or heated air inside the protective suit, thereby controlling the body temperature of the protective suit wearer and reducing sweat or moisture inside the protective suit. This can be done to create a more pleasant work environment.

In addition, the heating/cooling system using the thermoelectric module is eco-friendly as it does not require a separate refrigerant, and it generates relatively low noise compared to other cooling devices, so there may be less inconvenience caused by noise. In addition, compared to other cooling and heating devices, the thermoelectric module is small and light in size, which is advantageous for local cooling/heating, and at the same time can have the advantage of being easy for a user to carry or wear on the body. In addition, as described above, the temperature of the thermoelectric module can change according to the flow of current, so relatively accurate and fine temperature control is possible. Of course, it may have the advantage that it can be used as a heating device. Hereinafter, in the present specification, the surface to be cooled in the thermoelectric module is referred to as a cooling surface, and the surface to be heated is referred to as a heating surface.

According to the technical idea of the present invention, the heating and cooling system 1 for protective clothing includes an internal circulation space including a cooling surface of the thermoelectric module centered on the thermoelectric module inside the housing 100, and a heating surface of the thermoelectric module. It may be implemented so that the external circulation space including the can be physically separated from each other. The configuration of the heating and cooling system 1 for the protective suit will be described with reference to FIG. 4 .

4 shows a schematic configuration of a heating and cooling system for protective clothing according to an embodiment of the present invention.

Referring to FIG. 4 , the air conditioning system 1 for protective clothing according to an embodiment of the present invention provides a housing 100 , a thermoelectric module 200 provided in the housing 100 , and air into the housing 100 . It may include a fan (eg, 310 , 320 ) for inflow, and/or a connection hose 130 that communicates with the housing 100 so that cold air flows from the housing 100 . According to an embodiment, the heating and cooling system 1 for protective clothing may further include a condensate collecting unit 400 for collecting condensed water generated on the cooling surface 220 of the thermoelectric module 200 .

As described above, in the inside of the housing 100, the internal circulation space 110 and the external circulation space ( 120) may be formed.

In the embodiment shown in the drawings, the case in which the heating and cooling system 1 for protective clothing is utilized as a cooling device is shown. That is, the figure shows a case in which air inside the protective suit is connected to the inside of the protective suit and circulates through the cooling surface 210 of the thermoelectric module 200 . This is a case in which the heating and cooling system 1 for protective clothing functions as a cooling device as described above, and when the heating and cooling system 1 for protective clothing is used as a heating device, the cooling surface 210 and the heating surface 220 ) are interchanged, so that the cooling surface 210 of the current drawing may be heated and the heating surface 220 of the current drawing may be cooled. In this case, heated air may be supplied to the inside of the protective suit.

Hereinafter, the case where the heating and cooling system 1 for protective clothing functions as a cooling device will be mainly described, but even when the heating and cooling system 1 for protective clothing functions as a heating device, the configuration and effects of the present invention may be equally applied. will be easily deduced to an average expert in the technical field to which the present invention pertains.

On the other hand, the inlet fan 300 introduces an inner inlet fan 310 that introduces the inner air 10 inside the protective suit into the inner circulation space 110 and the external air 20 into the outer circulation space 120 . It may be made to include an external inflow fan (320). The internal inflow fan 320 and the external inflow fan 320 may be respectively disposed to be positioned at the lower and upper ends of the housing 100, respectively, and depending on the embodiment, the internal inlet fan 320 and the external The inlet fan 320 may be disposed to face each other at one end of the housing 100 . However, in the embodiment of the present invention shown in the drawings, since the condensate collecting unit 400 for collecting condensed water is formed at the lower end of the housing 100, in this case, the external inlet fan 320 is installed in the housing 100 ), the internal inflow fan 320 and the external inflow fan 320 may circulate cold air and warm air in opposite directions, respectively.

Meanwhile, according to an embodiment, the inner inlet fan 310 may be connected to the coupling part 500 coupled to the fixed holder 600 communicating with the protective clothing.

The coupling part 500 may be coupled to the fixed holder 600 so that the heating and cooling system 1 for the hazmat suit can be fixed to the hazmat suit. In particular, the coupling unit 500 is the fixed holder 600 . When coupled to the fixed holder 600, a predetermined connection passage (not shown) may be formed to communicate with the inside of the protective suit. For this reason, when the internal inlet fan 320 is driven, the air inside the protective suit is introduced into the internal circulation space 110 of the housing 100 through the fixed holder 600 and the coupling part 500 . can And the introduced internal air 10 is cooled while passing through the cooling surface 220 of the thermoelectric module 200 in the internal circulation space 110, and cold air is supplied to the inside of the protective suit through the connection hose 130. The inside of the protective suit can be cooled.

As described above, the connection hose 130 is connected to the connection holder 600-1 through the connection part 140 to supply cold air to the inside of the protective suit, thereby providing the fixed holder 600 and the coupling part 500. , the internal inlet fan 320, the internal circulation space 110, the connection hose 130, the connection part 140, the connection holder 600-1, and a circulation line circulating the inside of the protective suit may be formed. That is, according to the technical idea of the present invention, by circulating only the air inside the protective suit (that is, the internal air 10) without introducing external air for cooling or heating the inside of the protective suit, the penetration of various infectious disease viruses or contaminants is prevented. It is possible to ensure sufficient cooling while faithfully keeping the main function of the protective clothing worn for the purpose.

Depending on the embodiment, the heating and cooling system 1 for protective clothing may include a predetermined filter in the internal circulation space 110 , and may be mixed with the internal air 10 introduced through the internal inlet fan 320 . It is also possible to filter out infectious substances or contaminants such as viruses.

Meanwhile, as is well known, the cooling efficiency of the cooling surface 220 may vary according to heat dissipation of the heat generating surface 220 of the thermoelectric module 200 . Therefore, in the present invention, the external air 20 is introduced into the external circulation space 120 including the heating surface 220 of the thermoelectric module 200 through the external inlet fan 320 , and the thermoelectric module 200 is heated. The heat dissipation to the heating surface 220 may be made. In addition, an outlet 121 may be formed in the housing 100 so as to be in communication with the external circulation space 120 so that the heat heated while passing through the heating surface 220 can be discharged.

Conversely, when the heating and cooling system 1 for the protective clothing functions as a heating device, the air heated from the heating surface circulates inside the protective clothing, heat radiation to the heating surface is naturally made, and the cooled air on the cooling surface is discharged to the outside. can be emitted.

After all, according to the technical idea of the present invention, the housing so that the cooling surface 220 and the heating surface 220 of the thermoelectric module 200 can be physically separated in the inner circulation space 110 and the outer circulation space 120, respectively. (100) can be formed. Due to this configuration of the present invention, the air 10 inside the protective suit is introduced into the inner circulation space 110 to pass through the cooling surface 220 of the thermoelectric module 200 and cooled, and the cooled air is returned to the inside of the protective suit. While supplying, cooling can be achieved only by circulation of the air 10 inside the protective suit. Of course, even in the case of heating, only circulation of the air 10 inside the protective clothing may be performed. In addition, when the cooling function is performed, the heat dissipation of the heat generating surface 220 of the thermoelectric module 200 is performed using only the external air 20, so that cooling of the protective clothing is possible while the external air 20 is fundamentally prevented from flowing into the protective clothing. It can have a beneficial effect that can be prevented.

On the other hand, as the cooling surface 220 of the thermoelectric module 200 is cooled to a relatively very low temperature, condensed water may occur due to a temperature difference with the incoming air (eg, the internal air 10 inside the protective suit). In many cooling devices, if such condensate is not properly treated, cooling efficiency is greatly reduced, and it may cause abnormalities in the device itself, so the treatment of condensate may be a very important issue.

5 is a view for explaining a method of removing the condensed water of the heating and cooling system for protective clothing according to an embodiment of the present invention.

Referring to FIG. 5 , in the heating and cooling system 1 for protective clothing according to an embodiment of the present invention, a condensate collecting unit 400 for collecting condensed water may be formed in the housing 100 . In this case, a condensate flow path through which the condensed water generated from the cooling surface 220 of the thermoelectric module 200 moves may be formed in the internal circulation space 110 of the housing 100 . The condensed water may move from the cooling surface 220 of the thermoelectric module 200 through the condensed water passage and may be collected in the condensed water collecting unit 400 as indicated by a dotted line in the drawing.

According to an embodiment of the present invention, the air conditioning system 1 for protective clothing may include a collecting case 410 that collects condensed water in the condensed water collecting unit 400 and is detachably formed from the housing 100 . there is.

Depending on the embodiment, a predetermined moisture absorption sheet 430 capable of absorbing the collected condensed water may be provided inside the collection case 410 . In this case, when a small amount of condensed water is collected in the collecting case 410 , the condensed water can be collected while preventing the condensed water from sloshing inside the collecting case 410 according to a user's movement.

The condensed water passage may be formed to communicate from the inside of the housing 100 to the outside, so that the condensed water may be discharged to the outside of the housing 100 .

However, there is a risk that an external infectious material or contaminant may be introduced into the housing 100 due to the condensed water passage communicating with the outside.

Therefore, in a state in which the collecting case 410 is coupled to the housing 100, it is connected to the condensed water passage to collect condensed water flowing along the condensed water passage, and the collecting case 410 is connected to the housing 100. In the separated state, it is necessary to block the condensate flow path to prevent the external air 20 or external infectious substances and/or contaminants from flowing into the housing 100 . A configuration for this will be described with reference to FIGS. 6 to 7 .

6 and 7 are views for explaining a connection method of the condensate collecting case of the heating and cooling system for protective clothing according to an embodiment of the present invention.

First, referring to FIG. 6 , the air conditioning system 1 for protective clothing according to an embodiment of the present invention collects condensed water formed so that the collection case 410 can be detachably coupled to a predetermined position of the housing 100 . part 400 may be included.

As described above, a condensate flow path 420 for inducing condensed water generated from the internal circulation space 110 of the housing 100 may be formed inside the housing 100, and the condensate collecting unit 400 is disposed on one side. It may be formed to communicate with the condensed water passage 420 .

In addition, a first opening/closing means 450 capable of opening and closing the communication portion of the condensate collecting unit 400 may be formed. According to an example, the first opening/closing means 450 may open and close the communication portion of the condensate collecting unit 400 in a sliding manner and open and close in a sliding manner.

In addition, a predetermined push switch 440 for operating the sliding of the first opening/closing means 450 may be formed inside the condensate collecting unit 400 .

And when the collecting case 410 is coupled to the condensed water collecting unit 400 as shown in FIG. 6A , the push switch 440 is pressed by the collecting case 410 while the first opening/closing means 450 is pressed by the collecting case 410 . ) is slid to open, and the condensed water can be collected in the collecting case 410 while the condensed water flow path 420 and the condensed water collecting unit 400 communicate with each other.
