The fluid introduced into the first space 111a through the second outlet 124 of the heat exchanging unit 120 connected to the upper end of the first space 111a flows through the first space 111a, 2 is moved to the pump 150 side through the first outlet 113 located at the lower end of the first space 111a in a state where mixing with the fluid stored in the second space 111b is minimized.

The supplemental fluid supplied to the second space 111b through the supply port 115 of the storage tank 110 is supplied to the fluid communication passage 116a side by the second blocking wall disposed below the supply port 115 Direct movement is prevented. Therefore, it is possible to prevent direct mixing of the fluid passing through the first space 111a and the supplementary fluid supplied to the second space 111b by being heated or cooled to the target temperature.

Since the storage space 111 of the storage tank 110 is closed at one side of the cover 122 of the heat exchange unit 120, the supplementary fluid stored in the second space 111b is discharged to the outside of the heat exchange unit 120 Exchanged with the surface and heated or cooled to a temperature close to the target temperature. Therefore, the temperature of the fluid passing through the first space 111a can be prevented from being rapidly changed by the supplementary fluid flowing into the first space 111a through the fluid connection passage 116a.

Hereinafter, the operation of the above-described second embodiment of the cold / hot water circulating apparatus for mat will be described.

18 is a schematic configuration diagram of the hot / cold water circulating apparatus for a mat according to the second embodiment of the present invention, FIG. 19 is a sectional view of FIG. 12, and FIG. 20 is a cross sectional view of a mat according to the second embodiment of the present invention FIG. 21 is a sectional view of the storage tank of the hot / cold water circulating apparatus for a mat according to the second embodiment of the present invention, and FIGS. 22 to 24 are sectional views of the second and third embodiments of the present invention FIGS. 25 to 26 are sectional views showing the operation of the plug according to the second embodiment of the present invention.

18, the heat exchanging unit 120, the storage tank 110, and the pump 150 are disposed on the second flow path connected to the first flow path of the mat.

A thermoelectric element 130 capable of heating or cooling the fluid passing through the heat exchanging part 120 is disposed at one side of the heat exchanging part 120 and a heat dissipating part 140 is disposed at the other side of the thermoelectric element 130 . Meanwhile, the thermoelectric element 130 controls the temperature and the polarity of the power supplied to the thermoelectric element 130 according to the user's input signal, as well as the switching of the heat radiation or the heat absorption mode.

In the second embodiment of the present invention, the mat may be divided into at least two regions L and R as in the modification of the first embodiment. In order to control the two regions independently, The inlet end of the second flow path connected to the outlet end may be branched into two, and the valve and the temperature sensor may be respectively disposed on the branched inlet end.

That is, when the user selects at least one region through the input unit, the control unit provides a control signal for opening the valves V1 and V2 connected to the selected corresponding region, and the valves V1 and V2 supply the control signals So that the inflow end of the second flow path of the corresponding region is opened to allow the fluid to circulate in the selected region. At this time, the valves V1 and V2 may be solenoid valves capable of opening and closing the inlet end of the second flow path according to the control signal of the controller.

In addition, a temperature sensor for measuring the temperature of the fluid is disposed at the front end of the valves (V1, V2), and the amount of opening and closing of the valve is controlled in accordance with the temperature of the fluid measured by the temperature sensor, can do.

On the other hand, the first flow path of the mat may be detachably assembled with the second flow path through the connector 170 and the plug 160. The fluid heated or cooled while passing through the second flow path is supplied to the first flow path side through the outlet connection port 161 of the plug 160 and the inlet connection port 171 of the connector 170, The fluid is recovered to the second flow path side through the outlet connection port 172 of the connector 170 and the inlet connection port 162 of the plug 160. [

19, the thermoelectric element 130 is adhered closely to one side surface of the heat transfer block 121, and the heat dissipation portion 140 is formed on the other side surface of the thermoelectric element 130. As shown in FIG. And the fluid recovered in the first flow path is heated or cooled by the thermoelectric element 130 while passing through the heat exchange part 120 disposed on the second flow path.

That is, the fluid introduced into the heat exchanging unit 120 through the second inlet 123 is heated or cooled while passing through the flow space S between the heat transfer block 121 and the

cover

122, 124, respectively.

As shown in FIG. 20, the flow space S flows in a staggered manner by a plurality of partition walls 122a for partitioning the flow space S, so that heat exchange in the flow space S The moving path is extended and the turbulence is formed by the engagement protrusion 122b disposed on the movement path, so that the heat exchange efficiency of the fluid is improved. Particularly, since the flow space S forms an interval of about 1.5 mm between the heat transfer block 121 and the cover 122, the fluid passing through the flow space S can be quickly heated or cooled.

The fluid discharged through the second outlet 124 of the heat exchange unit 120 is transferred to the storage tank 110 and then transferred to the first flow path side by the transfer pressure of the pump 150.

21, the fluid discharged through the second outlet 124 of the heat exchanging unit 120 is discharged to the upper end of the first space 111a of the storage tank 110, The fluid stored in the first space 111a is discharged through the first outlet 113 located at the lower end of the first space 111a.

On the other hand, when the supply fluid is supplied to the supply port 115 of the storage tank 110 for replenishing the fluid, the supply fluid is separated from the first space 111a by the first blocking film 116, And the supply fluid supplied to the second space 111b is moved to the first space 111a through the fluid connection passage 116a formed in the first blocking layer 116. [ That is, the fluid passing through the first space 111a and the supply fluid supplied to the second space 111b are rapidly mixed by heating or cooling, and the temperature of the fluid passing through the first space 111a is suddenly changed Can be prevented.

The supply fluid supplied to the supply port 115 strikes the second blocking film 117 disposed between the supply port 115 and the fluid connection path 116a to form a turbulent flow in the second space 111b The supply fluid can be prevented from moving directly to the fluid connection passage 116a and mixing with the fluid in the first space 111a.

Particularly, the first space 111a and the second space 111b constituting the storage space 111 of the storage tank 110 are opened at one side and closed by the cover 122 of the heat exchange unit 120 . Accordingly, the supply fluid stored in the second space 111b is adjusted to a temperature close to the target temperature while being heated or cooled by the heat exchanging unit 120, so that the amount of the fluid passing through the first space 111a It is possible to prevent a sudden change in temperature.

Since the first space 111a is formed in a relatively small size as compared with the second space 111b, the fluid that has been heated or cooled to the target temperature in the heat exchanging unit 120 and discharged through the second outlet 124 Can be mixed with the fluid stored in the first space 111a to minimize the temperature change.

As described above, the fluid recovered in the second flow path is transferred to the first flow path side through the heat exchanging part 120 disposed on the second flow path, the storage tank 110, and the pump 150 in a heated or cooled state And supplied again.

The first flow path and the second flow path can be connected or disconnected by the connector 170 and the plug 160. In the connected state, the separation mechanism 175 prevents the disconnection.

22, the inlet-side end portion and the outlet-side end portion of the first flow path are connected to the inlet connection port 171 and the outlet connection port 172 of the connector 170, respectively, and the inlet- And the outflow side end portion are connected to the inlet connection port 162 and the outlet connection port 161 of the plug 160.

The inlet port 171 is connected to the outlet connection port 161 and the outlet connection port 172 is connected to the inlet connection port 162 and the inlet connection port 171 is connected to the outlet connection port 161. In the state where the connector 170 and the plug 160 are engaged, The outflow prevention check valve 173 provided in the outlet 171 and the outlet connection port 172 and the outflow preventing check valve 163 provided in the inlet connection 162 and the outlet connection 161 are moved in the axial direction, The fluid circulates on the first flow path and the second flow path.

The backflow prevention check valve 174 provided in the inlet port 171 of the connector 170 opens the flow passage when the fluid is supplied through the inlet end of the first flow passage and opens the flow passage when the fluid flows in the reverse direction. .

23, when the connector 170 and the plug 160 are coupled to each other and the flow path is opened, sudden pressure is applied to the mat, so that the fluid received in the first flow path passes through the inlet port 171, It is possible to prevent the fluid from flowing back toward the outlet 161 of the plug 160 by blocking the flow passage by the check valve 174 provided at the inlet port 171 .

24, when the connector 170 and the plug 160 are separated from each other, the outflow prevention check valve 173 provided in the inflow connection port 171 and the outflow connection port 172, When the connector and the plug 160 are separated from each other, the outflow preventing check valve 163 provided in the outflow connector 161 and the outflow connector 161 closes the flow path while being moved to the original position by the elastic force of the respective elastic members, It is possible to prevent the fluid of the first flow path and the second flow path from flowing out.

The supply port 115 of the storage tank 110 may be opened or closed by a stopper 118.

25, a stopper 118 for closing the supply port 115 of the storage tank 110 is provided with a through hole 118b for connecting the storage space 111 of the storage tank 110 and the outer space. The check valve 118c disposed in the inner space of the cap 118 is moved downward by its own weight and the check valve 118c is closed when the check valve 118c is moved downward. Is opened, the pressure of the storage space 111 of the storage tank 110 is maintained at the atmospheric pressure level.

There is no fear of backflow into the storage tank 110 when the pump 150 is operated. However, when the backflow occurs due to the pressure applied to the mat side in the state where the pump 150 has stopped operating due to reaching the target temperature, the water level in the storage space 111 of the storage tank 110 rises, The fluid or vapor may be discharged through the through hole 118b of the through hole 118.

26, when the backflow prevention check rod 118c is moved upward as the backflow pressure acts in the accommodation space 111 of the storage tank 110, the backflow prevention check rod 118c, It is possible to prevent the fluid or vapor from being discharged to the outside through the through hole 118b.

In particular, the check valve 118c is provided with a sleeve 118e provided at the lower end thereof, engaged with the flow guide 118f formed on the upper surface of the finishing cap 118d and guided upward and downward, The backflow pressure is discharged to the inside of the sleeve 118e, and the backflow prevention check rod 118c is raised. Therefore, the backflow pressure discharged through the flow guide 118f is effectively transmitted to the sleeve of the backflow prevention check rod 118c. As a result, even when the backflow pressure is small, the backflow prevention check rod 118c is moved upward, The operational sensitivity of the non-return check rod 118c is improved.
