Description

The present invention relates to a hot water circulation device, and more particularly, to a hot water circulation device including a storage section for storing water, a heating section to which the water stored in the storage section moves and is heated, and a circulation pipe through which the hot water heated by the heating section moves to the storage section, the heating section being seated and installed on a heat generating section of a portable stove, the water supplied to the inside of the heating section being heated by the heat generated in the heat generating section of the portable stove, and the heated hot water circulating through the circulation pipe installed in the heating section of a cushion, chair, mat, etc. without a separate power source to provide heating.

Generally, portable stoves use butane gas as fuel, are small in size and easy to carry, can be used in small spaces, and are designed to be convenient and safe to use outdoors in the cold winter.

For this reason, portable stoves are widely used in winter or other cold seasons to beat the cold when enjoying leisure activities such as hiking and fishing outdoors or when carrying out various types of work.

Such a conventional portable stove includes a body having a leg at the bottom and a handle at the top, and a ceramic heater mounted at the front lower part of the body via a square recessed heater fixture.

A reflector is provided around the periphery of the ceramic heater, a safety net is provided at the front of the ceramic heater, internal heat exhaust ports are provided at the upper part of the ceramic heater and the upper surface of the main body, and a pilot burner and a spark plug are installed at the center of the lower end of the ceramic heater.

In addition, a space is provided at the bottom of the back of the main body in which a portable butane gas container can be placed, and the upper surface or one side surface of the main body is provided with levers for ignition, extinguishing, and gas supply adjustment.

However, such conventional portable stoves only have the function of dissipating heat to beat the cold outdoors, and the warmth is only felt in front of the ceramic heater or near the outlet, so they are insufficient to provide warmth to the user's entire body.

As a prior art for solving such problems, Korean Patent Registration No. 10-1075132 discloses a hot water boiler and a portable stove that doubles as a coffee pot. The technical configuration of the device includes a body that houses a gas cylinder and has a heat generating part that burns gas supplied from the gas cylinder to generate heat, a water tank that is attached to the body so that water can be stored therein, and a circulation pipe that is connected between the inlet and outlet of the water tank and circulates the water stored in the water tank, and the circulation pipe includes a hot and cold water pipe made of a metal material that passes through the heat generating part and heats the water flowing inside.

However, the above-mentioned conventional technology requires a hot water pipe to be installed so as to pass through the main body, which means that it cannot be easily applied to conventional portable stoves.

Meanwhile, Korean Patent Publication No. 10-2017-0076400 discloses a hot water circulation device that includes a storage section for storing water, a heating section through which the water stored in the storage section moves and is heated, and a circulation pipe through which the hot water heated by the heating section circulates, the heating section being installed by sitting on the heat generating section of a portable stove, so that the water supplied to the inside of the heating section is heated by the heat generated by the heat generating section of the portable stove, and the heated hot water circulates through the circulation pipe installed on a cushion, chair, etc. to provide heating. However, because the heating section is formed in a simple rectangular tube shape, when all the water is heated and evaporated, problems such as overheating and the heating section being damaged or exploding occur.

The present invention relates to a hot water circulation device 100 including a storage section for storing water, a heating section through which the water stored in the storage section moves and is heated, and a circulation pipe through which the hot water heated by the heating section moves to the storage section, the heating section being seated and installed on a heat generating section of a portable stove, the water supplied to the inside of the heating section being heated by the heat generated by the heat generating section of the portable stove, and the heated hot water circulating through the circulation pipe installed in the heating section of a cushion, chair, mat, etc. to provide heating without a separate power source.

As shown in Figures 1 to 5, the configuration of the present invention includes a storage section 110 in which a large amount of water is stored, a heating section 120 in which the water stored in the storage section 110 moves and is heated, and a circulation pipe 130 in which the hot water heated in the heating section 120 circulates.

More specifically, the storage unit 110 has a space formed therein for storing water, and an inlet 112 formed on one side for injecting water.

At this time, the inlet 112 is provided with a plug 114 to prevent foreign matter from entering the inside of the storage unit 110 .

In addition, the stopper 114 may be provided with an inlet 114a connected to the circulation pipe 130 described later, and configured to close the inlet 112 and allow the hot water circulated from the circulation pipe 130 to flow back into the storage section 110, and the inlet 114a may be installed at the inlet 112.

A handle 110a may be formed on the upper end of the storage unit 110 so that the hot water circulator 100 can be easily carried.

Meanwhile, the heating unit 120 is formed in a box shape with a space formed therein so that the water supplied from the storage unit 110 can be stored therein.

That is, an outlet 116 is formed on one side of the storage unit 110, and a water supply pipe 121 is provided in the heating unit 120. The outlet 116 and the water supply pipe 121 are connected to each other so that the water stored in the storage unit 110 can move to the heating unit 120.

At this time, the water supply pipe 121 is provided with a check valve 121a so that the water stored in the storage unit 110 can be supplied to the heating unit 120 side, thereby preventing the water that has moved to the heating unit 120 from moving back to the storage unit 110 and allowing the water to easily circulate through the circulation pipe 130 described below.

In addition, the check valve 121a is disposed in a direction parallel to the upper surface of the heating unit 120, and even if the heating unit 120 is heated by the heat generating unit 18 and the internal pressure rises, the effect of the pressure rise is minimal on the check valve 121a, thereby enabling water to be supplied from the storage unit 110 to the heating unit 120.

That is, if the check valve 121a is installed vertically on the upper surface of the heating part 120, the opening and closing part may be opened by its own weight, which may cause the opening and closing part to be unable to operate smoothly.

Meanwhile, a first connecting pipe 122 is provided on an upper surface of the heating unit 120, to which the water supply pipe 121 is connected, and a second connecting pipe 124 is provided on the other upper surface, and the circulation pipe 130 is connected between the second connecting pipe 124 and an inlet 114a provided in the plug 114 of the storage unit 110.

Therefore, the water moving from the storage unit 110 along the water supply pipe 121 to the heating unit 120 is heated in the heating unit 120 to generate hot water. As the internal pressure of the heating unit 120 increases due to heating, the heated hot water is supplied to the circulation pipe 130 via the second connection pipe 124 without being backflowed to the storage unit 110 by the check valve 121a, and after heating the heating unit, it moves back to the storage unit 110, thereby circulating.

In this case, the circulation pipe 130 is installed inside the seat, backrest, cushion, mat, etc. of the chair, and is made of a flexible material and formed in a zigzag shape, so that it can provide more efficient heating to a user seated on a chair or mat, etc.

In addition, an orifice 124a is provided inside the second connecting pipe 124, and pressure is applied so that the hot water heated in the heating unit 120 can move to the circulation pipe 130 and circulate therethrough, which has the effect of eliminating the need for a separate circulation pump and preventing noise.

At this time, as shown in FIG. 6, a check valve 124b is further provided in front of the orifice 124a, so that heated water can be supplied from the heating unit 120 to the circulation pipe 130 side, and the movement of water from the circulation pipe 130 to the heating unit 120 side is prevented.

In addition, the check valve 124b is installed in a direction parallel to the upper surface of the heating unit 120. If the check valve 124b is installed perpendicular to the upper surface of the heating unit 120, the opening and closing unit may open due to its own weight, which may cause the opening and closing unit to not operate smoothly.

At this time, when the hot water heated in the heating unit 120 moves to the circulation pipe 130, a negative pressure is applied inside the heating unit 120, and the water in the storage unit 110 is sucked in to replenish the water in the heating unit 120.

A connecting rod 118 is formed at the bottom of the storage unit 110, and a connecting port 126 to which the connecting rod 118 is connected is formed at the top of the heating unit 120. The connecting rod 118 is inserted into the connecting port 126 by a fastening member 126a such as a bolt, so that the connection between the storage unit 110 and the heating unit 120 becomes more solid.

At this time, the storage unit 110 may be directly connected to the heating unit 120 at a connection port 126 by a method such as welding.

Meanwhile, the heating part 120 has a protruding part 120a extending downward from a rear end thereof.

At this time, after the hot water generated by heating the heating unit 120 by the heat generating unit 18 is discharged to the circulation pipe 130 side, even if water supply from the storage unit 110 is stopped, a certain amount of water is always accumulated under the protrusion 120a due to the shape of the protrusion 120a, so that it is possible to prevent a situation in which the heating unit 120 is heated to an empty state, and it is possible to prevent accidents such as damage or explosion of the heating unit 120 due to overheating.

That is, when the heating unit 120 is full, hot water can be discharged through the second connecting pipe 124 provided at the upper part of the heating unit 120; otherwise, a certain amount of water is always stored in the protruding portion 120a, so that the inside of the heating unit 120 can be prevented from being heated to an empty state, and overheating and damage or explosion can be prevented.

In addition, the protrusion 120a is formed with an inclination such that the rear surface faces the front as it approaches downward, so that the water vapor generated from the hot water heated by the heating unit 120 rides on the inclined rear surface of the protrusion 120a and more smoothly collects below the protrusion 120a, which has the effect of more stably maintaining the state in which water is always accumulated below the protrusion 120a, and the heating effect is also improved as the area in contact with the heat generating unit 18 is increased.

Meanwhile, the heating unit 120 is installed in the body 12 of the portable stove 10 and is seated on the top of the heat generating unit 18 that dissipates heat, and the water that moves to the heating unit 120 is heated to produce hot water.

Here, the portable stove 10 has a gas cylinder 20 inserted into a gas cylinder insertion section 14 provided on the main body 12, and gas supplied from the gas cylinder 20 generates heat in the heating section 18, dissipating the hot air to the surrounding area.This configuration is well known and is not claimed in the present invention, so a detailed explanation will be omitted here.

However, the heating unit 120 has the advantage that it can be easily applied to existing portable stoves 10 since installation is completed by simply seating it on the heat generating unit 18 of the portable stove 10 .

At this time, a seating portion 128 is provided at the bottom of the heating portion 120 so that it can be stably seated on the heat generating portion 18 of the portable stove 10, and the seating portion 128 is formed in a shape corresponding to the heat generating portion 18 with the bottom open.

A ventilation hole 128a is formed through the front part of the seating part 128, so that the gas supplied to the heating part 18 can be easily discharged to the outside, thereby making it possible to use the portable stove 10 safely, and also allowing the hot air emitted from the heating part 18 to pass through, thereby allowing it to function as a stove.

In addition, an open portion 128b is formed at the rear portion of the seating portion 128, which allows the hot air from the heat generating portion 18 to be smoothly transferred to the protruding portion 120a of the heating portion 120, thereby improving the heating efficiency.

Furthermore, the heating unit 120 is provided with a safety net 129 at a certain distance in front of the seating unit 128, which is configured to prevent a user from approaching the heat generating unit 18, the heating unit 120, and the seating unit 128, thereby preventing injury.

The operation of the hot water circulating apparatus 100 having the above-mentioned configuration will be described below.

First, the hot water circulation device 100 is installed on the portable stove 10 while in use, with the seating portion 128 of the heating portion 120 seated on top of the heat generating portion 18 of the portable stove 10 .

Next, water is supplied to the reservoir 110 via the inlet 112 of the reservoir 110 .

Next, water moves to the heating unit 120 along the water supply pipe 121 connected to the outlet 116 of the storage unit 110, and the water supplied to the heating unit 120 is heated by the heat generating unit 18 to produce hot water.

Next, the hot water heated in the heating section 120 is supplied to the circulation pipe 130 via the second connecting pipe 124, making it possible to provide heat to a user seated in a heating section such as a seat or mat of a chair 30 having a circulation pipe 130 through which the hot water passes.

Next, the hot water that has passed through the circulation pipe 130 is supplied to the storage unit 110 via the inlet 114a of the storage unit 110, and continuously circulates through the storage unit 110, the heating unit 120 and the circulation pipe 130, thereby providing heating to the seat of the chair 30.

Meanwhile, according to another embodiment of the hot water circulating device 100' according to the present invention, as shown in Figures 7 and 8, an inlet 113 may be formed separately from the inlet 112, and a first extension pipe 113a may be provided from the inlet 113 to the inside of the storage section 110.

At this time, the inlet 112 can be opened and closed by being coupled with a separate plug (not shown).

In addition, the first extension pipe 113a has a lower end slightly spaced from the inner bottom surface of the storage unit 110 and is formed in a wedge shape to facilitate smooth drainage of water.

Furthermore, since the first extension tube 113a is immersed in the water contained inside the storage unit 110, when the water is discharged from the first extension tube 113a, no negative pressure is applied, and the water can be discharged more smoothly.

In addition, a check valve 113b may be provided at the end connected to the inlet 113 to which the circulation pipe 130 is connected, allowing water to move from the circulation pipe 130 to the storage unit 110 and preventing water from moving from the storage unit 110 to the circulation pipe 130.

In addition, the check valve 113b is installed in a direction parallel to the upper surface of the storage unit 110. If the check valve 113b is installed perpendicular to the upper surface of the heating unit 120, the opening and closing part may open due to its own weight, which may cause the valve to not operate smoothly.

In addition, the first connecting pipe 122 may be provided with a second extension pipe 122 a inside the heating unit 120 .

Here, the second extension pipe 122a has a lower end slightly spaced from the inner bottom surface of the heating part 120 and is formed in a wedge shape to facilitate the discharge of water.

Furthermore, since the second extension tube 122a is immersed in the water contained inside the heating unit 120, when the water is discharged from the second extension tube 122a, no negative pressure is applied, and the water can be discharged more smoothly.

In addition, side plates 125 are provided on both sides of the heating unit 120 to prevent the heat generated from the heat generating unit 18 from escaping to the outside, thereby improving thermal efficiency.

A shielding plate 127 is provided on the front surface of the heating unit 120 at a certain distance from the safety net 129, so that hot air generated from the heat generating unit 18 can flow through the gap between the front surface of the heating unit 120 and the shielding plate 127, thereby transferring heat to the heating unit 120 again, thereby improving thermal efficiency.

In addition, a hanger 111 may be provided protruding from the rear surface of the storage unit 110 so that a handle (not shown) of the portable stove 10 can be hung and fixed on the hanger 111.

Meanwhile, as shown in FIG. 9, a foreign matter removing member 140 for removing foreign matter adhering to the inside of the check valve 121a may be further provided between the water supply pipe 121 and the check valve 121a.

At this time, when foreign matter is attached inside the check valve 121a and the ball member does not operate, the foreign matter removal member 140 forcibly moves the ball member to discharge the foreign matter, thereby allowing the check valve 121a to operate smoothly.

The foreign body removal member 140 includes a T-shaped pipe 142, an operating member 144 that is connected to the pipe 142, and an elastic member 146 that elastically supports the operating member 144.

A water supply pipe 121 is connected to one side of the pipe 142, and a check valve 121a is connected in a straight line to an operating member 144, so that water supplied from the water supply pipe 121 is supplied to the check valve 121a through the pipe 142.

The operating member 144 is formed to a length that allows it to be coupled to the inside of the check valve 121a. When one side of the operating member 144 exposed to the outside of the tube body 142 is pressed, the ball member of the check valve 121a is moved to discharge foreign matter attached inside to the heating unit 120.

Moreover, the elastic member 146 allows the operating member 144 to return to its original position again.

An O-ring 148 and a finishing nut 149 are provided on the outer circumferential surface of the operating member 144 coupled to the inside of the pipe 142, thereby preventing water that has flowed into the pipe 142 from leaking out.

Although the preferred embodiment of the present invention has been described above, the scope of the present invention is not limited thereto, but extends to those which are substantially equivalent to the embodiments of the present invention. Various modifications and variations can be made by those having ordinary skill in the art to which the invention pertains, without departing from the spirit of the present invention.
