It is set to operate only below, so that the user's body temperature can be kept warm in winter when the temperature is low.

The water-cooled cooling pipe 140 is embedded in the backrest 120 made of a metal material having a high heat transfer coefficient. More specifically, the water-cooled cooling pipe 140 may be selected from a metal material including aluminum (Al), stainless steel (SUS), copper (Cu), etc. having a high heat transfer coefficient, but is not limited thereto. The water-cooled cooling pipe 140 may have a circular or prismatic cross-sectional structure.

The hybrid cooling bench 100 according to the present invention has a structure in which water cooled by the cooler 150 is used as a refrigerant to circulate inside the water-cooled cooling pipe 140 . As a result, the hybrid cooling bench 100 according to the present invention, unlike a method of cooling air like an air conditioner, is closed in which water circulates into the water-cooled cooling pipe 140 embedded in the interior of the backrest 120 .

This will be described in more detail below with reference to the accompanying drawings.

FIG. 3 is an enlarged perspective view illustrating the heating wire member of FIG. 1 , which will be described in connection with FIG. 1 .

1 and 3, the hot wire member 130 is a conductive metal wire 132, a glass fiber layer 134 covering the conductive metal wire 132, and a carbon fiber layer covering the glass fiber layer 134. 136 and a waterproof coating layer 138 covering the carbon woven yarn 136 .

As the conductive metal wire 132, at least one selected from copper, nickel, tungsten, aluminum, gold, silver, and the like may be used. It is preferable that 10 to 30 strands of the conductive metal wire 132 are braided in a twisted structure.

The glass fiber layer 134 serves to cover the surface of the conductive metal wire 132 to enhance strength. In this case, the glass fiber layer 134 may be made of glass fiber woven yarn.

The carbon woven yarn 136 is a conductor that conducts current and is a heat generating means that generates heat by self-resistance when a current is applied. In addition, due to the nature of the carbon woven radiation 136 , when current is applied, far-infrared rays and negative ions that are beneficial to the human body may be emitted together. Accordingly, the conductive metal wire 132 and the carbon woven yarn 136 have a structure that cancels the magnetic field generated as the current progresses.

The waterproof coating layer 138 is disposed on the outermost side of the heating wire member 130, and serves to prevent the heating wire member 130 from being exposed to moisture or water.

This waterproof coating layer 138 is 10 to 25% by weight of fluororesin, 20 to 40% by weight of methyl methacrylate resin, 2,4-diphenyl-6-(2-hydroxy-4-ethoxyphenyl)-1, A waterproof coating composition composed of 0.5 to 3% by weight of 3,5-triazine, 0.1 to 5% by weight of a surfactant, and the remaining solvent may be used. That is, the waterproof coating layer 138 may be formed by spray-coating the waterproof coating composition on the surface of the carbon woven yarn 136, drying, and curing.

A fluororesin is a synthetic resin having a structure in which some or all of the hydrogens of polyolefins in which the main chain is composed of C-C bonds are replaced with fluorine atoms, and has the weakest surface tension, so it is suitable as a water-repellent or oil-repellent component. By significantly increasing the contact angle of the waterproof coating layer, the fluororesin is splashed or agglomerated even when rainwater with strong surface tension comes into contact with the surface of the waterproof coating layer to fundamentally block the penetration of rainwater into the inside of the heating wire member.

Examples of such fluororesins include polytetrafluoroethylene (PTFE), tetrafluoroethylene/hexafluoropropylene copolymer (FEP), tetrafluoroethylene/perfluoroalkyl vinyl ether copolymer (PFA), polyvinyladenum fluoride (PVDF), etc. One or more selected types may be used.

When the amount of the fluororesin added is less than 10% by weight of the total weight of the waterproof coating composition, the content of the fluororesin is small and it is difficult to properly exhibit the waterproofing function. Conversely, when the amount of the fluororesin added exceeds 25% by weight of the total weight of the waterproof coating composition, chemical stability is lowered, and transparency is reduced due to an increase in viscosity, which may leave contamination, which is not preferable.

Methyl methacrylate resin is harmless to the human body and has excellent environmental friendliness, and is used as the main binder of the waterproof coating composition.

When the amount of methyl methacrylate resin added is less than 20% by weight of the total weight of the waterproof coating composition, there is a problem of lowering durability due to deterioration of mechanical properties. Conversely, when the amount of methyl methacrylate resin added exceeds 40% by weight of the total weight of the waterproof coating composition, there is a problem of lowering the numerical stability due to excessive use of the resin.

2,4-diphenyl-6-(2-hydroxy-4-ethoxyphenyl)-1,3,5-triazine is added for the purpose of improving adhesion. When the amount of 2,4-diphenyl-6-(2-hydroxy-4-ethoxyphenyl)-1,3,5-triazine added is less than 0.5% by weight of the total weight of the waterproof coating composition, the effect of improving the adhesion is not properly achieved. It can be difficult to perform. Conversely, when the addition amount of 2,4-diphenyl-6-(2-hydroxy-4-ethoxyphenyl)-1,3,5-triazine exceeds 3% by weight of the total weight of the waterproof coating composition, it is more Since it can act as a factor that increases only the manufacturing cost without increasing the above effect, it is not economical.

Surfactants serve to improve hydrophilicity. When the amount of the surfactant added is less than 0.1% by weight of the total weight of the waterproof coating composition, there is a problem in that the hydrophilicity of the coating film is weakened. Conversely, when the amount of the surfactant added exceeds 5% by weight of the total weight of the waterproof coating composition, there is a problem in that moisture is weak and durability is lowered.

As such, in the present invention, as the heating element 130 embedded in the seat portion 110 , the conductive metal wire 132 , the glass fiber layer 134 , the carbon woven yarn 136 , and the waterproof coating layer 138 are waterproof including the waterproof coating layer 138 . By using the carbon heating wire, it is not only safe for the human body, but also has excellent durability and waterproof properties, so that there is no problem in use even if it is installed outdoors.

Meanwhile, FIG. 4 is an enlarged cross-sectional view illustrating the detection sensor of FIG. 1 , and FIG. 5 is an enlarged perspective view illustrating the detection sensor of FIG. 4 , which will be described in connection with FIG. 1 .

1 , 4 and 5 , the detection sensor 160 includes a conductive composite layer 161 , a first electrode 162 , and a second electrode 163 .

The conductive composite layer 161 includes a non-conductive elastic substrate 161a and a conductive filler 161b dispersedly disposed inside the non-conductive elastic substrate 161a.

The non-conductive elastic substrate 161a is polyethylene, nylon, polystyrene, polyacrylonitrile, ethylene vinyl acetate, polypropylene, polyacrylate, polyurethane, polyvinylbutylal, polyvinyl chloride, EPDM (ethylene propylene rubber), PDMS (polydimethylsiloxane) may include one or more selected from the group consisting of.

The conductive filler 161b is uniformly distributed in three dimensions inside the non-conductive elastic substrate 161a to selectively impart conductivity to the conductive composite layer 161 by an electrical tunneling effect. The conductive filler 161b may include at least one selected from Ag, Au, Al, Cu, Pt, Ni, and the like.

The conductive composite layer 161 preferably has a thickness of 10 to 20 mm. When the thickness of the conductive composite layer 161 is less than 10 mm, it may be difficult to uniformly disperse and arrange the conductive filler 161b particles in the conductive composite layer 161 in three dimensions. Conversely, when the thickness of the conductive composite layer 161 exceeds 20 mm, it may act as a factor to increase only the amount of the non-conductive elastic substrate 161a and the conductive filler 161b without further increasing the effect, so it is not economical.

The first electrode 162 is disposed on the lower surface of the conductive composite layer 161 , and the second electrode 163 is disposed on the upper surface of the conductive composite layer 161 .

Each of the first and second electrodes 162 and 163 may be formed of at least one selected from Ag, Pt, Pd, Ni, Cu, and the like. In this case, each of the first and second electrodes 162 and 163 may have a thickness of 0.5 to 2 mm, but is not limited thereto.

In addition, the detection sensor 160 according to the present invention may further include a first electrode connection line 164 , a second electrode connection line 165 , and a pressure gauge 166 .

The second electrode connection line 165 is disposed between the second electrode 163 and the pressure gauge 166 to electrically connect the second electrode 165 and the pressure gauge 166 .

In the detection sensor 160 according to the present invention, when an external force is applied to the first electrode 162 or the second electrode 163 by the user's seating, the conductive composite layer 161 is compressed in the direction in which the external force is applied. and an electrical tunneling effect occurs between the conductive filler 161b particles in the compressed region. Accordingly, current is applied between the first and second electrodes 162 and 163 to detect whether the user is seated.

That is, when a predetermined pressure is applied to the first electrode 162 of the detection sensor 160 , the current or resistance of the detection sensor 160 is changed, and the change process is performed between the first electrode connection line 164 and the second electrode 162 . The intensity of the pressure is measured through the pressure gauge 166 through the electrode connection line 165, and when the intensity of the measured pressure is equal to or greater than a set value, it is determined that the user is seated.

As a result, since the detection sensor 160 according to the present invention has a characteristic that the volume and electrical resistance value change reversibly according to an external force, it is possible to easily determine whether the user is seated by sensing the intensity of the external force.
