1 shows an apparatus for supplying hot and cold water according to the present embodiment.

The cold / hot water supply device 100 is provided separately from the cold / hot mat 200 to circulate and supply water to the cold / hot mat 200 by heating or cooling the water. The cold / hot water supply device 100 may be connected to the cold / hot mat 200 via a hose 300. The hose 300 is made of a flexible material that can be freely bent, and is a pipe structure through which water flows inside, and is elongated to a suitable length to connect between the cold / hot mat 200 and the cold / hot water supply device 100. The hose 300 is, for example, a supply hose 310 for supplying water to the cold / hot mat 200 and a recovery hose 320 for circulating the water that has passed through the cold / hot mat 200 back to the cold / hot water supply device 100 It may include.

The cold and hot mat 200 is provided with a connector 210 connected to a hose on one side, and a pipeline through which water flows is connected to the connector. Accordingly, the hot or cold water supplied from the cold / hot water supply device 100 flows into the cold / hot mat 200 through the supply hose 310 and flows to the front of the cold / hot mat 200, and then the cold / hot water supply device through the recovery hose 320 ( 100). Then, it is re-heated or re-cooled again in the cold / hot water supply device 100 and circulated to the cold / hot mat 200. As the hot and cold water continues to circulate, the temperature of the cold and hot mat 200 may be increased or decreased to a set temperature.

As described above, the cold / hot water supply device 100 may increase or decrease the temperature of the cold / hot mat 200 while heating or cooling the water to an appropriate temperature and continuously circulating the cold / hot mat 200.

Hereinafter, a specific structure of the cold / hot water supply device will be described with reference to FIGS. 2 to 4.

2 is an exploded view of the configuration of the cold and hot water supply device according to the present embodiment, and FIGS. 3 and 4 show the assembled state of the cold and hot water supply device.

As shown, the cold / hot water supply device 100 of this embodiment includes a housing 10, a connecting connector 12 connected to a hose 300, a water container 20 for receiving water, and heating to supply water The unit 30 may include a cooling unit 40 for cooling water and a pumping unit for supplying cooling water.

The housing 10 forms the outer shape of the device 100 and protects the internal components. In addition, a circuit board 16 for controlling and driving each component may be provided inside the housing 10.

The shape and size of the housing 10 can be variously modified according to design specifications. On the upper portion of the housing 10, a stopper 21 that substantially opens and closes the inlet of the upper portion of the water bottle 20 may be located. Thus, by opening and closing the stopper 21 from the outside of the housing 10, the water can be filled into the water tank 20 through the inlet, or the water inlet 20 can be closed by blocking the inlet.

On the side surface of the housing 10 on which the cooling unit 40 is disposed, a slit-shaped window 18 through which external air flows may be further formed. Accordingly, as the outside air flows to the cooling unit 40 inside the housing 10, heat generated in the cooling unit 40 can be more easily dissipated.

A connection connector 12 for connection with the hose 300 may be installed on one side of the housing 10. The connection connector 12 may be applied in various ways such as a one-touch plug type coupling method or a nut type fastening structure.

The connecting connector 12 includes an outlet 14 through which the supply hose 310 is fitted and an inlet 15 through which the recovery hose 320 is fitted. The connection connector 12 is connected to the connector 210 of the cold / hot mat 200 through a hose. In this embodiment, the connecting connector 12 may include two outlets 14 and two inlets 15. The number of the outlet 14 and the inlet 15 of the connection connector 12 may be variously set.

The water bottle 20 is installed inside the housing 10 and forms a space for receiving water therein, and has an inlet for water injection at the top. A stopper 21 is installed at the entrance.

In this embodiment, the water tank 20 may have a structure capable of separately receiving water for supplying a heating unit for hot water and for supplying a cooling unit for cold water.

Thus, the water accommodated in the water tank 20 is used separately for the heating unit or the cooling unit, so that only a small amount of water in each space can be heated or cooled. Therefore, the heating and cooling of the water is performed quickly, so that the cooling / heating mat 200 can be cooled or heated in a shorter time to reach a desired temperature.

To this end, the water tank 20 has a partition wall 22 installed therein and is divided into two spaces, a hot water space 24 and a cold water space 25. An inlet hole 23 for introducing water supplied from the water tank 20 into the cold water space 25 from the hot water space 24 may be formed on the partition wall 22. Since the inlet of the water tank 20 is disposed above the hot water space 24, water injected into the water tank 20 through the inlet is primarily filled in the hot water space 24. Then, the water filled above the inlet hole 23 formed on the partition wall 22 flows into the cold water space 25 through the inlet hole 23 and is filled in the cold water space 25. The hot water space 24 of the water tank 20 is connected to the heating part 30, and the cold water space 25 is connected to the cooling unit 40.

The water accommodated in the hot water space 24 is supplied to the heating unit 30. The heating unit 30 heats the water supplied from the water tank 20 and discharges it to the cold / hot mat 200 through the outlet 14 and the supply hose 310. The water circulated in the cold / hot mat 200 is transferred to the inlet 15 through the recovery hose 320 and returned to the water container 20.

Between the inlet 15 and the bucket 20, a return pipe 31 is installed to return the water circulated to the inlet 15 through the cold / hot mat 200 to the bucket 20. The return pipe 31 may be connected to the hot water space 24 of the water tank 20. Return pipes 31 are connected to each of the two inlets 15, and each return pipe 31 extends to both sides of the water tank 20, respectively, and communicates with the water tank 20. Thus, the water accommodated in the hot water space 24 of the water tank 20 is heated through the heating part 30 and then supplied to the hot water mat 200 through the outlet 14 and after passing through the hot water mat 200. The hot water space 24 is returned through the return pipe 31 connected to the 15.

In this way, the water heated by the heating unit 30 can circulate the cold / hot mat 200 and the hot water space 24, thereby increasing the cold / hot mat 200 to a set temperature.

The heating unit 30 is connected to the hot water space 24 of the water tank 20, and at least one heating tube 32 for heating the water transferred from the hot water space 24, the water heating tube of the water tank 20 It may include a one-way check valve 33 to flow into (32). In FIG. 2, the heating part 30 illustrates a structure having two heating tubes 32, but the heating tubes 32 may be provided in various numbers in addition to the two. The heating tube 32 is connected between the hot water space 24 and the outlet 14 of the water tank 20 and heats water transferred to the inside.

One end of the heating tube 32 is connected to the hot water space 24 of the water tank 20. A fitting pipe 34 is installed at the tip of the heating tube 32 in the hot water space 24. The cover 35 provided with the check valve 33 is screwed to the front end of the fitting pipe 34. Thus, by attaching the fitting tube 34 and the cover 35 to the heating tube 32 in a screw-fastening method, the check valve 33 can be more easily coupled to the heating tube 32.

The water accommodated in the hot water space 24 of the water tank 20 flows into the heating tube 32 through the check valve 33 and is heated. The one-way check valve 33 prevents hot water from flowing back into the water container 20. Thus, the hot water is moved toward the outlet 14 by the expansion pressure generated while the water boils inside the heating tube 32 and is transferred to the cold / hot mat 200 through a hose.

The heating tube 32 is a tube structure, and may be an electrothermal heater structure that generates heat using electric energy. 5, in this embodiment, the heating tube 32 may include a rib 36 extending from the center to the inner surface. The ribs 36 extend along the axial direction of the heating tube 32 and are provided with at least one along the inner circumferential surface, thereby dividing the heating tube 32 into a plurality of spaces. Accordingly, the water passes through a plurality of spaces partitioned by the ribs 36 in the heating tube 32, and the contact area with water in the heating tube 32 can be further increased through the ribs 36. . Therefore, it is possible to effectively heat the water in a short time by increasing the heat transfer effect inside the heating tube 32.

The rib 36 may have a concave-convex cross-sectional structure in which concave convex and convex portions are alternately formed on the surface. Accordingly, the contact area between the ribs 36 and water is increased, so that the heated water can be heated more effectively.

In addition, the ribs 36 extend along a horizontal plane passing through the center of the heating tube 32, and may be disposed at a relatively narrower gap relative to the horizontal plane.

By this structure, the water entering the heating tube 32 mouth side is divided up and down by the rib 36 crossing the horizontal plane to pass through the heating tube 32. Thus, the water is prevented from moving only due to the weight of the heating tube 32, and it is possible to heat the water by uniformly contacting the front surface of the heating tube 32.

The ribs 36 are densely arranged at narrower intervals above the heating tube 32 based on the horizontal plane, so that the heating amount can be relatively increased from above. When the heating tube is divided into a semi-circular shape up and down, the flow rate is higher through the lower portion than the upper portion. Accordingly, relatively more ribs are formed at the top, thereby increasing the amount of heating by increasing the cross-sectional area of heat transfer.

In addition, the size of the cross section of the rib 36 may gradually increase as it goes from the inner peripheral surface of the heating tube 32 to the center. Through this structure, water passing through the heating tube can be heated more effectively.

The pressure inside the heating tube 32 increases as water is heated in the heating tube 32. The check valve 33 installed at the tip of the heating tube 32 is a one-way valve that moves water only from the water bottle 20 to the heating tube 32, and the water moves toward the outlet 14 by the pressure inside the heating tube 32. Is done. That is, as the internal pressure of the heating tube 32 increases, the heated hot water is pushed out of the heating tube 32 and transferred to the outlet 14. The hot water is supplied to the cold / hot mat 200 through a supply hose 310 connected at the outlet 14.

In this embodiment, a connecting pipe 37 may be further installed between the heating tube 32 of the heating part 30 and the outlet 14. The connecting pipe 37 transfers the hot water heated in the heating tube 32 to the outlet 14. The connecting pipe 37 is formed with a separate pipe on the side and is connected to the cooling unit 40. That is, the heating unit 30 and the cooling unit 40 are connected to the outlet 14 via one connection pipe 37. Thus, hot water or cold water may be transferred to the outlet 14 through the connecting pipe 37.

6 shows another embodiment of the heating unit.

6, the heating unit 30 is installed on the outside of the heating tube 32 to transfer heat to the heat transfer body 80, heat transfer body 80 at least one thermoelectric element installed on one side (81) ), A heat dissipation unit 82 for cooling the thermoelectric element 81, and at least one heat pipe 83 inserted into and installed in the heat transfer body 80 may be further included.

The heat dissipation unit 82 may include, for example, a heat dissipation plate 85 and a heat dissipation fan 86. The heat dissipation unit is in close contact with the thermoelectric element 81 and may be fixedly installed on the heat transfer body 80 through a bolt.

The heat transfer body 80 is a block structure, and may be formed of a material having a high heat transfer rate. The shape of the heat transfer body can be variously modified.

A thermoelectric element 81 is closely attached to the outer surface of the heat transfer body 80. A guide 84 supporting a side surface of the thermoelectric element may be protruded at a position where the thermoelectric element 81 is installed. The assembly of the thermoelectric element 81 can be prevented by the guide 84.

A plurality of holes are formed through the inner side of the heat transfer body 80. A heat pipe 83 is inserted into the hole. In this embodiment, the heat pipe 83 may be installed between the thermoelectric element and the heating tube.

The heat energy generated by the thermoelectric element 81 is transferred to the heating tube 32 through the heat transfer body 80. In this process, the heat energy can be evenly transferred to the entire heating tube 32 by the heat pipe 83 installed on the heat transfer body 80. Accordingly, the water supplied to the heating tube can be more effectively heated by the heat energy generated by the heating tube 32 and the heat energy transferred from the thermoelectric element 81 to the heating tube.

Hereinafter, a structure for supplying cold water to the cold / hot mat 200 will be described.

The cold / hot water supply device 100 of the present embodiment provides cooling water through the outlet unit 14 through the cooling unit 40, the cooling unit 40 for cooling the water supplied from the water bottle 20, and the cooling unit 40 for cooling water supply through the outlet 14 200) may be included.

The cold water lowered to the low temperature in the cooling unit 40 is pressurized and transferred to the cold and hot mat 200 by the pumping unit.

The cooling unit 40 is a thermoelectric element 50 for generating cold energy, a cooling block 60 installed on one surface of the thermoelectric element 50 to transfer cold energy to the water supplied from the water bottle 20, the thermoelectric element ( It may include a heat dissipation unit installed on the other surface of 50).

The thermoelectric module 50 is a device that generates a temperature difference through a voltage difference by using a cooling effect generated when a bipolar semiconductor is combined. When a voltage is applied to the thermoelectric element, a temperature difference occurs on both sides of the element, and when a relatively high temperature surface is cooled to lower the temperature, the temperature of the other surface is rapidly lowered by the temperature difference.

The cooling block 60 cools the water by transferring the cold air generated in the thermoelectric element 50 to the water in the water tank 20. In this embodiment, the cooling block 60 may be a structure that is directly installed in the water tank 20 and applies cold air directly to the water accommodated in the water tank 20. The detailed structure of the cooling block 60 will be described later.

The pumping unit may include a cooling water pipe 41 connecting the cooling block 60 and the outlet 14, and a pump 42 installed in the cooling water pipe to circulate cold water.

The cooling water pipe 41 is connected to the cold water space 25 of the water tank 20. And the cooling water pipe 41 is installed on the side of the connecting pipe 37 and is connected to the outlet 14 via the connecting pipe 37. When the pump 42 is driven, the water in the cold water space 25 of the water tank 20 is transferred to the connection pipe 37 through the cooling water pipe 41 to flow to the outlet 14 and connected to the outlet 14 It is supplied to the cold / hot mat 200 through the supply hose 310. Here, reference numeral 43 denotes a branch pipe for branching the cooling water pipe 41 into two connecting pipes 37.

Between the connecting pipe 37 and the pump 42, one side of the cooling water pipe 41 may be provided with a one-way check valve 44 that blocks the cold water from flowing toward the pump. Thus, even if the heating tube 32 and the cooling water pipe 41 are connected to the connecting pipe 37, hot water that has passed through the heating tube 32 does not flow to the cooling water pipe 41 by the check valve 44. As mentioned above, the heating tube 32 is also provided with a check valve 33 at the tip, so that the cold water transferred through the cooling water pipe 41 also does not flow toward the heating tube 32.

The heat dissipation unit is a heat radiation plate (51) in close contact with the thermoelectric element (50), the heat dissipation plate (51) is inserted and installed at regular intervals, and the outer end has a plurality of heat pipes (52) and heat pipes extending outside the heat radiation plate (51) (52) It may include a heat dissipation case 53 that is installed in contact with the outer tip.

The heat pipe 52 is a heat exchange mechanism that transfers heat through a phase transition due to evaporation and condensation of the heat transfer fluid contained therein. Since a lot of techniques have been disclosed for the structure of the heat pipe, detailed description thereof will be omitted.

The heat dissipation plate 51 is a rectangular plate structure having a thickness, and the front surface is in close contact with the thermoelectric element 50. A stepped groove 54 for restricting the position of the side end of the thermoelectric element 50 may be recessed on the front surface of the heat dissipation plate 51 in close contact with the thermoelectric element 50. The groove 54 may be formed in a size corresponding to the size of the thermoelectric element 50. The groove 54 regulates the position of the thermoelectric element 50 when assembling the heat dissipation plate 51 and the thermoelectric element 50. Thus, the thermoelectric element 50 is seated in the stepped groove 54 at the contact surface of the heat dissipation plate 51 so that it can be precisely aligned with the heat dissipation plate 51 without being pushed outward or displaced.

In addition, a stepped groove 61 that regulates the position of the side end portion of the thermoelectric element 50 may also be recessed at the contact surface of the cooling block 60 contacting the thermoelectric element 50 so that the thermoelectric element 50 is seated. The groove 61 may be formed in a size corresponding to the size of the thermoelectric element 50. The groove 61 regulates the position of the thermoelectric element 50 when assembling the cooling block 60 and the thermoelectric element 50. Accordingly, the thermoelectric element 50 is seated in the groove 61 at the contact surface of the cooling block 60 so that it can be precisely fitted to the cooling block 60 without being pushed outward or displaced.

The heat dissipation plate 51 is formed with a plurality of holes 55 at which the heat pipes 52 are inserted at both sides. Each hole 55 is formed to extend deep inside the heat dissipation plate 51. On both sides of the heat dissipation plate 51, each hole 55 may be alternately formed alternately along the vertical direction. One end of the heat pipe 52 is inserted into each of the holes 55 disposed on the both sides of the heat dissipation plate 51 to be in contact with the inside of the heat dissipation plate 51. The outer tip of each heat pipe 52 extends outside the heat dissipation plate 51 to contact the heat dissipation case 53.

Accordingly, the heat conducted from the thermoelectric element 50 to the heat dissipation plate 51 is transferred to the tip of the heat pipe 52 and radiated to the outside through the heat dissipation case 53 in contact with the heat pipe 52.

The heat dissipation case 53 is installed along the periphery of the housing 10 of the device, and the front surface may be formed in a lattice or slit form to allow outside air to flow. The heat dissipation case 53 may be formed of a metal material having high thermal conductivity. The heat dissipation case 53 is in contact with the outside air flowing through the window 18 formed in the housing 10 to dissipate heat into the atmosphere.

In this embodiment, the heat pipe 52 may have a structure in which the outer tip is bent along the inner surface of the heat dissipation case 53 to continuously contact the heat dissipation case 53. Accordingly, the contact area between the heat pipe 52 and the heat dissipation case 53 is increased, so that sufficient heat exchange between the heat pipe 52 and the heat dissipation case 53 can be effectively achieved.

In this way, the heat transferred to the heat dissipation plate 51 is transferred to the large-area heat dissipation case 53 through the heat pipe 52 to dissipate heat, thereby more effectively dissipating the heat generated from the thermoelectric element 50 to the thermoelectric element. It is possible to increase the cooling efficiency by (50).

The heat dissipation unit of the present embodiment is further fitted to the heat pipe 52 and is disposed on the side of the heat dissipation plate 51, and a plurality of side plates are disposed at intervals on the surface to further include a radiator 70 for dissipating heat of the heat pipes 52. You can.

The radiator 70 has a structure in which a plurality of heat sinks 71 are formed to protrude outward from a body extending long along the side surface of the heat sink plate 51. The radiator 70 is in a state in contact with the atmosphere through the plurality of heat sinks 71, and heat transferred to the radiator 70 is quickly radiated to the air through the heat sink 71. The radiator 70 is formed with a plurality of holes 72 through which the heat pipes 52 penetrate, according to the heat pipe 52 arrangement position. The radiator 70 is fitted to the heat pipe 52 and disposed on the side surface of the heat radiation plate 51. Accordingly, the heat transferred from the heat dissipation plate 51 to the heat pipe 52 can be primarily dissipated through the radiator 70.

As described above, heat generated from the thermoelectric element 50 is transferred to the heat dissipation case 53 through the heat pipe 52 to dissipate to the outside, thereby enhancing heat dissipation effect. Moreover, the heat pipe 52 is in a state where the contact area with the atmosphere is greatly increased through the radiator 70, and heat conducted to the heat pipe 52 can be effectively dissipated through the radiator 70.

Accordingly, the apparatus can sufficiently and effectively dissipate heat generated from the thermoelectric element 50 even without driving a separate heat dissipation fan. Therefore, it is possible to fundamentally prevent noise generation due to the operation of the heat radiating fan.

Of course, as another embodiment, the apparatus may further include a heat dissipation fan 56 installed on the outside of the heat dissipation plate 51 and selectively driven. The heat dissipation fan 56 is selectively driven only when necessary to increase the heat dissipation effect. By briefly driving the heat dissipation fan 56 only when necessary, noise can be minimized.

In this embodiment, the coupling portion for coupling the thermoelectric element 50 and the heat dissipation portion and the cooling block 60 is structured to be fastened with a fixing bolt 57 through the center of the thermoelectric element 50.

That is, the coupling portion is fastened to the cooling block 60 by passing through the hole 59 formed in the front surface of the heat radiation plate 51 and the thermoelectric element 50 of the heat dissipation portion, and the thermoelectric element 50, the heat radiation plate 51, and the cooling block It may include a fixing bolt 57 for fixing the (60), an elastic member 58 that is resiliently installed between the fixing bolt 57 and the heat radiation plate (51).

For example, a hole 59 in which a fixing bolt 57 is inserted is formed in the heat dissipation plate 51, and a female screw in which the fixing bolt 57 is fastened to a position corresponding to the hole 59 in the cooling block 60 Holes are formed. And, the thermoelectric element 50 is also formed a hole 59 through which the fixing bolt 57 penetrates at a position corresponding to the hole of the heat dissipation plate. Accordingly, by fastening the fastening bolt 57 through the hole and fastening the female screw hole of the cooling block 60, the thermoelectric element 50 is pressed and assembled between the heat dissipation plate 51 and the cooling block 60 to be assembled. It becomes possible.

As described above, the fixing bolt 57 is mounted on the central portion of the thermoelectric element 50, so that the size of the cooling unit 40 can be further reduced, unlike the conventional one.

In addition, in the present embodiment, the cooling unit 40 may further include an elastic member 58 that is elastically installed between the fixed bolt 57 and the heat radiation plate 51. The elastic member 58 may be, for example, an elastic spring. The elastic member 58 is fitted to the fixing bolt 57 and can be elastically installed between the bolt head of the fixing bolt and the heat radiating plate 51.

The elastic member 58 applies an elastic force to the heat dissipation plate 51. The heat dissipation plate 51, the thermoelectric element 50 and the cooling block 60 are pressed by the elastic member 58 to be in close contact. The elastic member 58 cushions the shock applied to the cooling unit by thermal deformation of the thermoelectric element 50, and maintains the close contact between the heat dissipation plate 51 and the cooling block 60 to the thermoelectric element 50 do. The elastic member 58 absorbs and absorbs shocks transmitted to the heat dissipation plate 51 and the cooling block 60 as the thickness is changed by thermal deformation of the thermoelectric element 50.

7 shows the structure of a cooling block according to this embodiment.

As shown in FIG. 7, the cooling block 60 of the present embodiment is installed directly in the cold water space 25 of the water tank 20 and is configured to directly transfer cold air to water accommodated in the cold water space 25.

To this end, the cooling block 60 is installed through the O-ring 27 in the mounting hole 26 formed in the front of the cold water space 25 of the water tank 20. Accordingly, the cooling block 60 forms a part of the side of the cold water space 25 of the bucket 20.

The cooling block 60 is a rectangular plate structure, one surface of which is in contact with the water accommodated in the cold water space 25 through the mounting hole, and the other surface is in contact with the thermoelectric element 50. Accordingly, the cold air generated in the thermoelectric element 50 is directly transferred to the water in the cold water space 25 through the cooling block 60 to cool the water.

O-ring 27 is installed along the step surface along the periphery of the mounting hole 26 to seal between the mounting hole 26 and the cooling block 60. The cooling block 60 may be fixedly installed, for example, through a bolt in a mounting hole.

In this embodiment, a cooling flow path may be formed in the cold water space 25 of the water bottle 20 coupled with the cooling block 60 to form a flow of cold water according to contact with the cooling block 60. In order to form a cooling channel, the cooling block 60 has a plurality of guides 62 protruding to contact the partition wall 22 on the front side facing the cold water space 25 to form a cooling channel between the partition walls 22. It can be formed at intervals. The guide 62 is formed to extend along the horizontal direction in the water bottle 20, and may be formed by changing positions in a zigzag form with a gap in the vertical direction. Cooling water flows down from the top along the guide 62 according to the horizontal position of the guide 62.

In addition, the cover 28 covering the top of the water bottle 20 is inserted into the cold water space 25 of the water bottle 20, the vertical member 64 located on both sides of the guide 62 is further formed. The vertical member 64 is a bar structure extended in the vertical direction and is formed to have a thickness corresponding to an interval between the partition 22 and the cooling block 60 of the cold water space 25 to form a partition wall 22 and a cooling block ( 60). Accordingly, the vertical member 64 may be inserted into both sides of the guide 62 of the cooling block 60 to form a side wall of the cooling passage.

That is, the guide 62 extends in the horizontal direction between the partition wall 22 and the cooling block 60 to form a horizontal surface of the cooling passage, and the vertical member 64 extends in the vertical direction to form a sidewall of the cooling passage.

Accordingly, a cooling passage is formed in the cold water space 25 by the upper and lower guides 62 and the left and right vertical members 64. Therefore, the guide 62 is not formed according to the horizontal position of the guide 62, and the cooling water flows in a zigzag form to the place where the floor is opened. The cooling water pipe 41 is connected to the lower portion of the cold water space 25 of the water tank 20, and the cold water cooled through the cooling passage is transferred to the outlet 14 through the cooling water pipe 41 to the cold / hot mat 200. Is supplied.

In this embodiment, in addition to the cooling passage forming structure by the guide 62 and the vertical member 64, various structures may be applied to form the cooling passage in the cold water space 25 of the water bottle 20. For example, the guide is formed in the form of a flow path on the front side of the cooling block so that the guide can contact the partition wall without a separate vertical member to form a zigzag cooling channel. In addition, various shapes of the guide and the vertical member may be modified to form various types of cooling passages.

8 shows another embodiment of a cooling block.

As shown, in the present embodiment, the cooling block 90 is provided separately from the water bottle 20 to be connected to the water bottle. The cooling block 90 is a rectangular block structure, and an inlet 91 through which water flows into the side and an outlet 92 through which water is discharged are formed. Inside the cooling block 90, a cooling passage 93 connecting the inlet 91 and the outlet 92 is formed. The inlet 91 may be connected to the cold water space 25 of the water tank 20 through a separate supply line. The outlet 92 is connected to the pump 42 through a cooling water pipe 41. Accordingly, when the pump 42 is driven, the water accommodated in the cold water space 25 of the water tank flows into the inlet 91 of the cooling block 90 and flows along the cooling passage 93 formed inside the cooling block, and then is cooled. It is discharged through the outlet 92.

In this embodiment, the cooling passage 93 is easily formed in the cooling block 90 by forming a plurality of conduits 94 and a plurality of connecting conduits 95 in a straight line on the side of the cooling block 90. can do. In addition, except for the front end hole of the pipe 94 connected to the inlet 91 and the outlet 92, the stopper 96 is formed in the hole 94 and the connection pipe 95 formed on the side of the cooling block 90 Can be installed. The stopper 96 blocks the tip of the pipeline 94 and the connecting pipeline 95 except the inlet 91 and outlet 92 so that water does not leak and flows only from the inlet to the outlet.

The conduit 94 may be formed by penetrating the cooling block 90 between opposite sides. A plurality of pipelines 94 may be formed at intervals. One end of one of the pipelines 94 may form the inlet 91 of the cooling block. One end of one of the remaining pipelines may form the outlet 92 of the cooling block.

The connecting conduit 95 is formed on an adjacent side with an edge between the sides of the cooling block 90 where the conduit is formed. The connecting conduit 95 extends in a straight line from the side of the cooling block 90 to connect the adjacent conduits 94. In this embodiment, the connecting conduit 95 is formed at a right angle to the conduit 94 so that the conduit 94 and the connecting conduit 95 cross each other at right angles to each other. The connecting conduit 95 is not formed to penetrate completely between opposite sides of the cooling block 90, but may be formed only to the extent that it connects between adjacent conduits 94 in the interior. In addition, the connecting pipes 95 may be formed at different positions from each other on both sides of the cooling block 90. Accordingly, the cooling passage 93 inside the cooling block can achieve a zigzag shape.

As described above, by forming the pipeline 94 and the connecting pipeline 95 in a straight line in the single cooling block 90 made of a rectangular block structure, it is possible to easily form the cooling passage 93 inside the cooling block. Therefore, it is possible to more easily manufacture a cooling block.

The thermoelectric element 50 and the heat dissipation unit are fixedly installed on the cooling block 90 through a bolt. The cold air generated in the thermoelectric element 50 is transferred to the cooling block 90 to cool the water flowing along the cooling passage 93 of the cooling block 90. The heat generated in the thermoelectric element 50 is heat dissipated through the heat dissipation unit. The heat dissipation unit of this embodiment may include a heat dissipation plate 51 in close contact with the thermoelectric element 50 and a heat dissipation fan 56 installed outside the heat dissipation plate. As it passes, heat transferred to the heat dissipation plate is dissipated.

Hereinafter, the operation of the apparatus will be described.

Through this device, hot or cold water is supplied to the cold / hot mat 200 more quickly, so that the temperature of the cold / hot mat 200 can be increased or decreased.

The water supplied to the inlet of the bucket 20 is divided into two spaces and filled. Water is filled into the hot water space 24 and filled into the cold water space 25 through the inlet hole 23 of the partition wall 22. In this way, the water classified according to the purpose in the bucket 20 is used for each purpose.

For example, looking at the case of supplying hot water to the cold / hot mat 200, water accommodated in the hot water space 24 of the water tank 20 flows into the heating tube 32 through the check valve 33. When the heating tube 32 is heated according to the control signal of the circuit board 16, the water in the heating tube 32 is heated and the hot water heated by the internal expansion pressure supplies the outlet 14 and the supply hose 310. Accordingly, it is supplied to the cold / hot mat 200.

The hot water that has passed through the cold / hot mat 200 is recovered into the hot water space 24 of the water tank 20 through the return pipe 31 connected to the inlet 15. Through this circulation flow, it is possible to circulate by continuously heating only the water contained in the hot water space 24.

Therefore, by continuously heating and circulating only a part of the water contained in the water tank 20, it is possible to heat the water more effectively to increase the temperature of the cold / hot mat 200 to a desired temperature more quickly.

On the other hand, in the case of supplying cold water to the cold / hot mat 200, by rapidly cooling and supplying only the water contained in the cold water space 25 of the bucket 20 using the thermoelectric element 50, the cold / hot mat 200 is more quickly provided. ).

That is, the thermoelectric element 50 is driven according to the control signal of the circuit board 16 to cool the water, and the cooled water is transferred to the outlet 14 through the cooling water pipe 41 according to the driving of the pump 42. .

The cold air of the thermoelectric element 50 is directly applied to the water accommodated in the cold water space 25 of the water tank 20 through the cooling block 60 to cool the water in the cold water space 25. By cooling only some of the water accommodated in the cold water space 25 among the water accommodated in the bucket 20, it is possible to lower the temperature of the water more quickly and effectively.

The heat generated from the thermoelectric element 50 is transferred to the heat dissipation plate 51 and transferred to the radiator 70 and the heat dissipation case 53 through the heat pipe 52 installed on the heat dissipation plate 51 to dissipate into the air. . In this way, by maximizing the heat dissipation area with the atmosphere, heat of the thermoelectric element 50 can be dissipated more quickly and effectively.

Therefore, it is possible to cool the water in the cold water space 25 more rapidly by lowering the temperature of the cooling surface of the thermoelectric element 50.

Water accommodated in the cold water space 25 according to the driving of the pump 42 is transferred to the outlet 14 through the cooling water pipe 41. Then, it is supplied to the cold / hot mat 200 through a supply hose 310 connected to the outlet 14. As the cold water is supplied to the cold / hot mat 200, the water in the cold water space 25 is cooled while flowing down the cooling passage formed by the guide 62 and the vertical member 64. The cooled water is continuously supplied to the cooling / heating mat 200 through the cooling water pipe 41 according to the driving of the pump 42.

Cold water that has passed through the cold / hot mat 200 is recovered into the water tank 20 through the return pipe 31 connected to the inlet 15. The water recovered into the water tank 20 flows back into the cold water space 25 through the inlet hole 23 of the partition wall 22. The water flowing into the cold water space 25 flows down again along the cooling flow path and is cooled by heat exchange with the cooling block 60. Through this circulation flow, only the water contained in the cold water space 25 can be continuously cooled and circulated.

Therefore, only a part of the water accommodated in the water tank 20 is cooled while moving along the cooling passage, so that the water can be cooled more effectively to lower the temperature of the cold / hot mat 200 to a desired temperature more quickly.
