Description

PORTABLE HEATING SYSTEM

The present invention relates to a portable heating system, and more specifically, to a portable heating system for conveniently cooling and discharging high-temperature exhaust gas.

In general, a camper van is a vehicle equipped with various living facilities for long-term driving trips. It was mainly popular in Europe and other places where you can travel to neighboring countries by land, but recently in Korea, with the 5-day workweek, the use of leisure vehicles equipped with various living facilities, namely camper vans, is increasing. Camper vans are divided into types that can be used as vehicles by remodeling the interior of a bus or car like a house, and wagon types that are towed by a car like a trailer, and the interior is equipped with bedrooms, bathrooms, kitchens, etc. so that you can stay and cook while traveling.

Accordingly, camper vans are equipped with auxiliary facilities such as a water heater to generate hot water for showers, heating and cooling facilities to control the indoor temperature to an appropriate level, and cooking utensils for cooking. In order to use these auxiliary facilities, electricity and LPG are required as energy sources.

When sleeping in a camper van during the winter, leaving the vehicle engine on for heating consumes a lot of fuel, which is a huge cost burden, and there is also the problem of air pollution due to exhaust fumes from running the engine. Therefore, the use of idle heaters or portable heating systems has been increasing recently in camper vans or commercial vehicles that must be driven for long periods of time.

A silent heater is a heating device that directly heats the indoor and outdoor air and transfers the heat to the interior of a vehicle without turning on the engine. Compared to a conventional heating method using engine heat, it consumes only about 10% of the fuel, so it has the advantage of minimizing cost burden and environmental pollution problems.

However, in the case of camper vans, you can shower inside the vehicle, and if you use a hot water mat, you need to heat the water to charge the hot water mat. In the past, a separate water heater had to be installed to generate hot water, so there were problems such as separate fuel consumption due to the operation of the water heater, and securing installation space due to the additional installation of a boiler. In addition, as the number of campers is rapidly increasing among users of general vehicles or tents other than camper vans, the demand for portable heating systems is also increasing.

Here, the combustion module (20), the blower module (30), the hot water generation module (40), and the hot water circulation module (60) are provided in the built-in space (111), so that the portable heating system according to the first embodiment of the present invention can be configured compactly.

A portable heating system according to the first embodiment of the present invention may further include at least one of a hot water temperature sensor (631), an exhaust temperature sensor (70), a carbon monoxide sensor (80), and a thermoelectric module (50).

The hot water temperature sensor (631) is installed in the hot water return line (63) of the hot water circulation module (60). The hot water temperature sensor (631) measures the temperature of the water to control the water circulation pattern in the hot water circulation module (60). The hot water temperature sensor (631) is used as information for the control operation of the hot water control unit (96) described below.

The exhaust temperature sensor (70) is installed in the built-in space (111) adjacent to the air discharge unit (13). The exhaust temperature sensor (70) measures the temperature of air discharged to the air discharge unit (13) to control the indoor temperature. The exhaust temperature sensor (70) is used as information for the control operation of the setting control unit (95) described below.

The carbon monoxide sensor (80) detects carbon monoxide in the air flowing into the air inlet (12) to notify of a danger. The carbon monoxide sensor (80) is used as information for the control operation of the danger control unit (99) described below.

The thermoelectric module (50) is coupled to the hot water generation module (40) to charge the power. The thermoelectric module (50) generates power by the temperature difference between the exhaust gas temperature and the water temperature. The thermoelectric module (50) can charge the rechargeable battery (94) according to the operation of the charging control unit (98) described below.

A portable heating system according to the first embodiment of the present invention may further include a control module (90) that controls the operation of a combustion module (20), a blower module (30), a hot water generation module (40), and a hot water circulation module (60).

The control module (90) may include a switch (91) for selecting whether or not to electrically connect for the operation of the modules, an indoor temperature setting unit (92) for setting the temperature of the indoor space, a rechargeable battery (94) for charging power for the operation of the modules, and a setting control unit (95) for controlling the operation of at least one of the combustion module (20) and the blower module (30) in response to the set temperature of the indoor space.

For example, when the temperature of the indoor space is lower than the minimum value of the set temperature range of the indoor space, the setting control unit (95) can increase the combustion amount in the combustion module (20) to increase the temperature of the air discharged from the air discharge unit (13). As another example, when the temperature of the indoor space is within the set temperature range of the indoor space, the setting control unit (95) can maintain the combustion amount of the combustion module (20) or the air blowing amount of the blowing module (30) at the set state. As yet another example, when the temperature of the indoor space is higher than the maximum value of the set temperature range of the indoor space, the setting control unit (95) can decrease the combustion amount in the combustion module (20) to lower the temperature of the air discharged through the air discharge unit (13).

The control module (90) may further include a blower setting unit (93) that sets the amount of blown air in the indoor space. In addition, the setting control unit (95) may control the operation of the blower module (30) in response to the set temperature of the indoor space to adjust the amount of blown air in the indoor space.

The control module (90) may further include a hot water control unit (96) that controls the operation of the circulation pump (64) according to the temperature of the water measured by the hot water temperature sensor (631) to adjust the temperature of the water supplied to the hot water generation module (40).

For example, if the temperature of the water measured by the hot water temperature sensor (631) is lower than the minimum value of the preset return water temperature, the hot water control unit (96) can control the operation of the circulation pump (64) to reduce the water flow rate in the heat exchange coil (43) and increase the temperature of the water passing through the heat exchange coil (43). As another example, if the temperature of the water measured by the hot water temperature sensor (631) is within the preset return water temperature range, the hot water control unit (96) can control the operation of the circulation pump (64) to maintain the water flow rate in the heat exchange coil (43). As yet another example, if the temperature of the water measured by the hot water temperature sensor (631) is higher than the maximum value of the preset return water temperature range, the hot water control unit (96) can control the operation of the circulation pump (64) to increase the water flow rate in the heat exchange coil (43) and decrease the temperature of the water passing through the heat exchange coil (43).

The control module (90) may further include a cooling control unit (97) that controls the operation of the three-way valve (694) according to the temperature of the water measured by the hot water temperature sensor (631) to determine whether or not to circulate water to the cooling module (69).

For example, if the temperature of the water measured by the hot water temperature sensor (631) is lower than the preset cooling water temperature, the cooling control unit (97) controls the operation of the three-way valve (694) to open the discharge inlet, while opening the first outlet and closing the second outlet so that the water passing through the hot water return line (63) passes through the hot water recovery line (65) and is stored in the storage tank (61). As another example, if the temperature of the water measured by the hot water temperature sensor (631) is higher than the preset cooling water temperature, the cooling control unit (97) controls the operation of the three-way valve (694) to open the discharge inlet, while closing the first outlet and opening the second outlet so that the water passing through the hot water return line (63) passes through the cooling module (69) and the hot water recovery line (65) and is stored in the storage tank (61).

The control module (90) may further include a charging control unit (98) that monitors the power of the rechargeable battery (94) and controls the charging operation of the rechargeable battery (94) with power generated from an external power source or a thermoelectric module (50).

Looking at the operation of the portable heating system according to the first embodiment of the present invention, according to the operation of the blower module (30), indoor air or outdoor air is introduced into the air intake section (12) and then discharged through the combustion module (20) to the air discharge section (13), thereby controlling the temperature of the indoor space. At this time, since the combustion module (20) is operated, the air introduced into the built-in space (111) by the combustion module (20) can be heated.

And the exhaust gas generated by the combustion of fuel in the combustion module (20) is delivered to the hot water generation module (40) through the combustion transfer line (27). At this time, water stored in the storage tank (61) is supplied to the heat exchange coil (43) according to the operation of the circulation pump (64). Accordingly, as the water passes through the heat exchange coil (43), it cools the hot water exhaust line (42), so the exhaust gas is cooled while passing through the first exhaust line (421), the second exhaust line (422), and the third exhaust line (423) in sequence.

In particular, as the exhaust gas passing through the first exhaust line (421) in the hot water exhaust line (42) is cooled first by the water passing through the heat exchange coil (43), the exhaust gas discharge speed is reduced, as the exhaust gas passing through the second exhaust line (422) is cooled secondarily, the exhaust gas discharge speed is reduced, and as the exhaust gas passing through the third exhaust line (423) is cooled thirdly, the exhaust gas discharge speed is reduced, so that the noise caused by the movement of the exhaust gas in the hot water exhaust line (42) can be minimized.

And the exhaust gas discharged from the hot water exhaust line (42) is discharged outdoors through the combustion exhaust line (28), combustion exhaust connector (281), and combustion exhaust path (29) in a cooled state.

In addition, water passing through the heat exchange coil (43) via the cold water inlet line (611) is heated by the exhaust gas, and the heated water passes through the hot water transfer line (612) and the hot water quick connector (62), and then through the transfer path (633) of the circulation connector (63a) and the hot water connector to the hot water return line (63), where it is cooled. Here, since an insulating layer is formed on the circulation body (632), the heat of the water passing through the transfer path (633) is prevented from being released to the outside, and the risk of burns to the user at the circulation connector (63a) can be prevented. At this time, if the temperature of the water detected by the hot water temperature sensor (631) is lower than the preset cooling water temperature range, the cooling control unit (97) opens the discharge inlet in the three-way valve (694), opens the first outlet, and closes the second outlet, so that the water delivered to the hot water return line (63) passes through the hot water recovery line (65) by the pumping power of the circulation pump (64) and is stored in the storage tank (61).

And when the temperature of the water detected by the hot water temperature sensor (631) is higher than the preset cooling water temperature, the cooling control unit (97) opens the discharge inlet in the three-way valve (694), closes the first outlet, and opens the second outlet, so that the water delivered to the hot water return line (63) is cooled through the cooling inlet line (692), cooler (691), and cooling outlet line (693) by the pumping force of the circulation pump (64), and then stored in the storage tank (61) through the hot water recovery line (65).
