As leisure culture spreads and interest in camping grows, the types of camping are also becoming more diverse. In addition to the typical camping that involves setting up a tent, other examples include using a camping car or car camping using a regular car. Among these various types of camping, when using a vehicle such as a camping car and using a heater installed in the vehicle, heating must be done using the heat source generated when the engine is running while the engine is running, which reduces the risk of excessive fuel consumption and environmental pollution due to exhaust gases. There are problems, etc. To solve this problem, a non-starting heater that can be used without starting the vehicle was developed. Non-moving heaters are used in vehicles, but they are also used in general tents for heating.

A non-cooling heater is a heater that uses a heat source for heating. When operating, combustion gas is generated in the process of operating the heat source. This combustion gas was discarded, but recently, the waste heat of the combustion gas is used to generate hot water or to use hot water mats. A system that connects floor heating is being introduced. However, conventional hot water generating devices or hot water mat systems using the waste heat of non-cooling heaters can control the temperature of hot water only according to the temperature control of the non-cooling heater, and their structures are complex, so they are bulky and heavy, and do not properly control the temperature of hot water. Because there is no system, there are problems with usability and portability for various outdoor environments. there was.

The configuration of the hot water generating device using the waste heat of the idle heater of the present invention consists of a waste heat inlet pipe, a branch pipe, a valve opening and closing section, an exhaust pipe, a heat exchange pipe, and a heat exchange coil. The hot water mat system using the hot water generating device includes a non-moving heater, a hot water generating device connected to the exhaust pipe of the non-moving heater, a water tank and circulation pump that supply hot water to the heat exchange coil of the hot water generating device, and hot water from the heat exchange coil. It consists of a hot water mat that receives water and a controller that controls the system.

First, the hot water generating device 200 will be described. The hot water generator 200 is connected to the exhaust port of the silent heater. A silent heater is a device that can heat a room by heating a heat source. Combustion gas is generated in the process of heating the heat source, and this combustion gas is discharged through an exhaust port. The waste heat discharged through the exhaust port has a high temperature ranging from 260℃ to 300℃, so it can be used to generate hot water.

The hot water generator 200 includes a waste heat inflow pipe 210 that is connected to the exhaust port of the silent heater and receives the waste heat of the silent heater, and a valve opening and closing unit (210) that opens and closes the valve to control the flow of waste heat as needed for temperature control. 230), an exhaust pipe 240 connected to the valve opening/closing unit 230, a heat exchange pipe 250 through which the waste heat passes, and a heat exchange coil surrounding the heat exchange pipe 250 on the outside and exchanging heat with the heat exchange pipe 250. (260), it is composed of a branch pipe 220 through which waste heat entering through the waste heat inflow pipe 210 passes to the valve opening or closing portion or the heat exchange pipe.

First, the waste heat inflow pipe 210 that receives waste heat from the silent heater will be described. Figure 2 is a diagram showing a state in which the blocking valve 231 of the valve opening/closing unit 230 is closed in order to send waste heat to the heat exchange pipe. The waste heat inflow pipe 210 is a pipe that is connected to the exhaust port of the silent heater and introduces the waste heat of the silent heater. The waste heat inflow pipe may be bent as shown in Figure 2, but it can be combined in various forms, such as being connected in a straight line, depending on the connection structure with the silent heater. The waste heat inflow pipe 210 has a waste heat discharge port 211 through which waste heat is discharged at the end opposite to the part where the waste heat is introduced. The end of the waste heat outlet 211 is located close to the inclined inner surface of the branch pipe 220, which will be described later.

Next, the branch pipe 220 will be described. As can be seen in Figures 2 and 3, the branch pipe 220 inserts the waste heat inflow pipe 210 into the interior at one end, is connected to the valve opening/closing unit 230 at the other end, and has a heat exchange pipe 250 at the top. is connected to The branch pipe may be connected to the heat exchange pipe 250 at the bottom or side depending on the arrangement structure of the silent heater and the hot water generator 200.

The branch pipe 220 has the same internal width at the top and bottom as shown in Figures 2 to 4, but as it slopes at a certain position and becomes narrower, the space through which the waste heat passes is formed to be small at the part in contact with the end of the waste heat discharge port 211. do. Therefore, when it is desired to discharge waste heat to the outside as shown in Figure 3, when the waste heat entering the waste heat inlet pipe 210 exits through the waste heat discharge port 211 to the valve opening and closing unit 230, which will be described later, the waste heat in the branch pipe 220 The waste heat in the narrow space in contact with the discharge port 211 is sucked in by the flow of waste heat coming from the waste heat discharge port 211, and accordingly, the waste heat remaining in the heat exchange pipe 250 is also discharged to the exhaust pipe 240 through the branch pipe 220. It flows to and is discharged. At this time, the waste heat passing through the branch pipe 220 passes through the wide part inside the branch pipe 220 and reaches the gradually narrowing inclined part of the branch pipe 220 and the part in contact with the waste heat discharge port 211. Since the space through which waste heat passes is narrowed, the flow of waste heat becomes faster according to Bernoulli's theorem, allowing the waste heat to easily escape through the exhaust pipe 240, which will be described later.

Next, the valve opening/closing unit 230 will be described. The valve opening/closing unit 230 is connected to the end of the branch pipe 220 at one end, is connected to an exhaust pipe 240 to be described later at the other end, and has a blocking valve 231 therein. The valve opening/closing unit 230 opens and closes the blocking valve 231 to block or discharge waste heat coming from the discharge port of the waste heat inlet pipe 210 as needed. The valve opening/closing unit 230 can open and close the blocking valve using an actuator. The valve opening/closing unit 230 has an inner diameter of the portion where the blocking valve is provided larger than the inner diameter of the end connected to the branch pipe 220 and the end connected to the exhaust pipe 240. Accordingly, when the blocking valve is closed, the waste heat coming out of the waste heat discharge port 211 returns to the heat exchanger, and when the blocking valve is opened, the waste heat flowing out to the exhaust pipe 240 through the valve opening and closing part 230 is transferred to the valve opening and closing part with a large inner diameter (230). ) You can expect the effect of reducing noise by dispersing it internally.

In the present invention, when waste heat is sent to the heat exchange pipe 250 to exchange heat with the heat exchange coil 260 in order to generate hot water, the shutoff valve 231 in the valve opening/closing unit 230 is blocked. When the blocking valve 231 is blocked, as can be seen in Figure 2, the waste heat supplied from the waste heat discharge port 211 is blocked in the blocking valve 231, and the waste heat blocked in the blocking valve 231 blocks the flow of waste heat in Figure 2. As can be seen from the direction of the arrow, it returns to the direction it came from by riding the wall of the valve opening/closing unit 230. The waste heat flowing along the wall continues to flow along the wall of the branch pipe 220, and the waste heat passing through the branch pipe 220 passes through the heat exchange pipe 250 and is discharged, so it is stored between the heat exchange coils 260 in the process of passing through the heat exchange pipe. Heat exchange occurs.

On the other hand, when the hot water heated by the heat exchange unit reaches the set temperature and it is desired to stop heat exchange to prevent further heat exchange or to lower the temperature of the hot water, open the shutoff valve 231 and open the valve opening/closing unit 230 as shown in FIG. 3. do. When the valve opening/closing unit 230 is opened, the waste heat from the waste heat discharge port 211 passes through the valve opening/closing unit 230 and is discharged into the exhaust pipe 240. In addition, the waste heat discharged from the waste heat discharge port 211 absorbs the waste heat of the branch pipe 220 located close to the waste heat discharge port 211, and accordingly, the waste heat remaining in the heat exchange pipe 250 also flows in the direction of the branch pipe 220. moves to . At this time, the waste heat in the branch pipe 220 passes between the narrowing ramp of the branch pipe 220 and the waste heat discharge port 211, and as the speed increases according to Bernoulli's theorem, the hot waste heat in the heat exchange pipe is also sucked in and the exhaust pipe ( 240) and is discharged to the outside. Through this process, the hot air in the heat exchange tube is discharged to the outside, making it possible to maintain or lower the temperature of the heat exchange part. If the temperature falls below the set temperature, the temperature can be raised by blocking the valve opening and closing again to allow heat exchange. . In this way, the set temperature of the hot water can be maintained by repeatedly opening and closing the blocking valve 231. By applying this principle, the temperature of hot water may be adjusted by adjusting the opening angle of the blocking valve 231.

An exhaust pipe 240 is connected to the other end of the valve opening/closing unit 230. The exhaust pipe 240 is a pipe that discharges waste heat from the waste heat discharge port 211 and waste heat from the heat exchange pipe 250 to the outside when the valve opening/closing unit 230 is opened. The exhaust pipe 240 can be equipped with a silencer 241 to reduce noise.

Next, the heat exchange tube and heat exchange coil will be explained. The heat exchange pipe 250 is a pipe connected to the upper part of the branch pipe 220 and is a passage through which waste heat is discharged to the outside. Depending on the arrangement structure, it may be the lower part or the side of the branch pipe 220. When the valve opening/closing unit 230 is blocked, the waste heat coming out of the waste heat outlet 211 hits the blocking valve and returns, climbing up the wall of the branch pipe 220 and passing through the heat exchange pipe 250, as described above. It is discharged.

The heat exchange coil 260 is a coil surrounding the heat exchange tube 250. The heat exchange coil 260 is a coil through which water circulates. The water tank connector 261, which is at one end of the coil, is connected to the water tank 320, and the hot water mat connector 262, which is the other end, is connected to the hot water mat 500. do. The water coming out of the water tank 320 passes through the heat exchange coil 260 and exchanges heat with the heat exchange pipe 250, increasing its temperature. This hot water circulates through the hot water mat 500 and returns to the water tank 320. By going through this process, floor heating using the hot water mat 500 becomes possible. The heat exchange coil 260 may surround the heat exchange tube 250 in one layer or in two layers. In the case of wrapping in two layers, as can be seen in Figure 2, heat exchange also occurs between the two layers of heat exchange coils 260, so better thermal efficiency can be expected. The hot water mat connector 262 can also use the hot water itself by connecting it to a faucet, etc., rather than connecting it to the hot water mat 500.

The hot water generator 200 may be equipped with a detachable exhaust extension kit 270. The exhaust pipe extension kit 270 is configured to integrate the exhaust line by connecting the end of the heat exchange pipe 250 through which waste heat is discharged and the end of the exhaust pipe 240. The exhaust pipe extension kit 270 may be composed of a first exhaust pipe pipe (271), a second exhaust pipe pipe (272), and a third exhaust pipe pipe (273). The first exhaust pipe 271 is connected to the end of the heat exchange pipe 250 that discharges waste heat, the second exhaust pipe 272 is connected to the end of the exhaust pipe 240 that discharges waste heat, and the third exhaust pipe 273 ) is a configuration that connects the first exhaust pipe and the second exhaust pipe into one pipe to discharge waste heat through one pipe.

When connecting the exhaust port extension kit (270), if the valve opening/closing part (230) is opened to discharge waste heat, the waste heat in the heat exchange pipe (250) close to the branch pipe (220) is discharged to the second exhaust port through the branch pipe (220). It is discharged to the third exhaust pipe 273 through the extension pipe 272, and the waste heat around the first exhaust pipe 271 is discharged through the first exhaust pipe 271 and the third exhaust pipe 273. At this time, while the waste heat maintains the flow direction toward the branch pipe (C in Figure 4), the flow direction toward the heat exchange pipe (C' in Figure 4) is weakened due to the pressure relationship, so that the flow at both ends within the heat exchange pipe can be offset. Therefore, temperature control can be facilitated by minimizing the flow amount of waste heat in the heat exchange tube and significantly lowering the heat exchange function.

As can be seen in Figure 4, the arrangement of each extension pipe of the exhaust pipe extension kit is connected by placing the first exhaust pipe pipe (271), which has a weak waste heat flow pressure, in front of the third exhaust pipe pipe (273), and the waste heat flow pressure These relatively strong second exhaust pipes (272) are arranged alternately behind the area where the first exhaust pipes (271) meet, so that waste heat discharged through the first exhaust pipes (271) flows through the second exhaust pipes (272). Backflow can be prevented by the pressure of waste heat discharged through it.

The operating principle of the hot water generating device 200 using the non-cooling heater of the present invention is as follows. First, when attempting to generate hot water using the present invention, the valve opening/closing unit 230 is blocked while the non-cooling heater is in operation. When the valve opening/closing unit 230 is blocked, the waste heat flowing into the waste heat inflow pipe 210 is blocked by the blocking valve 231 and rises up the inner wall to the heat exchange pipe 250, and the heat exchange coil surrounding the heat exchange pipe 250 ( 260) exchanges heat with the heat exchange tube 250 to heat the hot water inside.

On the other hand, when the heated hot water reaches the set temperature or is too hot and the temperature needs to be lowered, the valve opening/closing unit 230 is opened. When the valve opening/closing unit 230 is opened, the waste heat entering the waste heat inlet pipe 210 flows through the exhaust pipe 240. Since the waste heat in the heat exchange pipe 250 is also discharged through the exhaust pipe 240, the hot water in the heat exchange coil 260 no longer rises. By repeating this process of opening and closing the valve, the temperature of the hot water can be adjusted to the desired temperature regardless of the strength of the non-moving heater.

Next, the hot water mat 500 system using the hot water generating device 200 will be described. The hot water mat 500 system of the present invention consists of a non-moving heater, a hot water generator 200, a water tank 320, a circulation pump 310, a controller 400, and a hot water mat 500.

As can be seen in Figure 1, the exhaust pipe 240 of the silent heater is connected to the waste heat inlet pipe 210 of the hot water generating device 200, and the connection port 261 of the water tank 320 of the heat exchange coil 260 is It is connected to the water tank 320, and the hot water mat 500 connector 262 is connected to the hot water mat 500, and a temperature sensor 510 is attached to the position where hot water flows into the hot water mat 500. You can check the temperature of the hot water flowing into ). The hot water mat 500 is connected to the water tank 320, and the hot water that enters through the hot water mat 500 connector 262 and circulates through the hot water mat 500 returns to the water tank 320 and continuously circulates hot water. Let me do it..

A circulation pump 310 can be installed between the heat exchange coil 260 and the water tank 320 to rotate the water, and a flow sensor 330 can be attached to the circulation pump 310 to check the flow of water.

Meanwhile, the valve opening/closing unit 230 of the hot water generating device 200 is connected to the controller 400. The controller 400 is connected to the hot water generator 200, circulation pump 310, flow sensor 330, and temperature sensor 510 to control the entire hot water mat 500 system. When the hot water temperature is set in the controller 400, the temperature of hot water flowing from the heat exchange coil 260 to the hot water mat 500 is checked, and when it is necessary to lower the hot water temperature, the blocking valve 231 of the valve opening/closing part 230 is opened. And, when it is necessary to increase the hot water temperature, the shutoff valve 231 of the valve opening/closing unit 230 is blocked to control the hot water mat 500 to maintain the set temperature.

The hot water generated by the hot water generator 200 may be used by itself without being connected to the hot water mat 500.

Above, in the detailed description of the present invention, specific embodiments have been described, but it will be obvious to those skilled in the art that various modifications are possible without departing from the scope of the present invention.
