In recent years, as domestic conditions and environment have become more abundant in Korea, various leisure activities are being activated, and leisure activities using camper cars are increasing.

Motorhomes are vehicles equipped with various living facilities for long or long-term leisure activities (ie, driving trips). They are activated mainly in Europe where they can travel to neighboring countries by using land routes. Recently, Leisure activities and long-distance trips using leisure vehicles, such as camper cars, are being promoted due to improvements in conditions (working five days a week) and living conditions (such as income increase).

As described above, the camping car used in leisure activities and long-distance trips is divided into various types of vehicles (minibus, truck, mid-size bus, etc.) as a house and a wagon type that is driven by a car such as a trailer Inside, there is a living room with a sofa bed so that you can cook, relax and stay while traveling, as well as convenience facilities such as toilets and kitchens.

In the winter season when the seasonal change is severe and the temperature and humidity are extremely changed and the temperature is significantly lowered in the use of a camper car equipped with various facilities as described above, You should have a safe rest and stay.

As a conventional camcorder provided with a device for warming the indoor space as described above, there are a Korean Patent Laid-Open No. 10-2014-0121519 (a camper car equipped with a briquetting boiler), a Japanese Patent Laid-Open No. 10-2015-0063712 (Hot water and heating system of a vehicle using heat), Patent Publication 10-2017-0097439 (block type heater assembly for a camper), Patent Publication 10-2017-0121620 Patent No. 10-1308603 (low-temperature type combined boiler apparatus for a camper), Registered Patent No. 10-1785571 (heating system of a camper car), Registration No. 10-1773051 (heating apparatus of a camper car), and the like are known.

[0006] In the above-mentioned Japanese Patent Application Laid-Open No. 10-2014-0121519 (a camper car equipped with a briquetting boiler), a cage, which is detachably mounted on a floor of a truck, is formed as a closed rectangular parallelepiped with a door on one side, And a briquetting boiler is installed outside the one side of the cage to circulate the hot water to the heating oven.

However, since the briquetting boiler is installed and used, there is a problem of safety due to the generation of briquetting gas, and there is a problem that the briquette should be replaced occasionally, and there is a need to dispose of the burned briquette.

Open No. 10-2015-0063712 (hot water and heating system of the vehicle using the engine heat of the vehicle) is designed to use the engine heat of the vehicle, and when the air conditioner or the air conditioner of the vehicle is used for cooling or heating, Since the engine of the automobile must be operated to operate the apparatus, the atmosphere and the natural environment due to the idling of the engine are contaminated, the automobile oil is consumed, and the operation cost is increased, and noise due to the operation of the engine is generated .

Open No. 10-2017-0097439 (a block-shaped heater assembly for a camper) is configured such that air heated by a preheater of a camcorder flows into the interior of the main body, so that heat from the preheater passes through the interior of the main body It is possible to increase the internal temperature without turning on the camcorder, and especially to warm the floor without heating the air.

However, since the air heated by the preheater of the camper is simply introduced into the interior of the body, if the engine of the vehicle is operated to start the preheater, the atmosphere and the natural environment due to idling of the engine are contaminated. Of the oil is consumed and the operation cost is high, and also the noise due to the operation of the engine is generated.

Japanese Patent Application Laid-Open No. 10-2017-0121620 (a hot water system for a vehicle using an ignorable heater) is a system in which a fuel gas is sucked from a fuel tank of a differential vehicle to operate ignorant heaters and the exhaust heat of the exhaust gas The heater is heated, and the heat storage material heated in the heater is stored in the heat storage tank.

However, this is because the heat of the heat accumulator is heated by the heat of the heater by using the exhaust heat of the igniter heater which is driven by the fuel of the differential car, and the heating process is complicated by double heating, Since the ignition heater and the heater are separately provided and operated, the equipment cost and the operating cost are increased, and the heat is not efficiently utilized and is wasted.

In addition, in the patent No. 10-1308603 (low-temperature type combined boiler apparatus for a camper), a heater rod operated by a heat source is installed in the tank inside of the solar cell or external power, And the hot water generated by the hot water generating unit is supplied to the user through the hot water pipe by the pump and circulated and supplied along the heating pipe at the same time.

This is because the heat source is supplied through the already installed heating pipe in such a manner that the heated air is discharged to the inside of the camping car through a separate heat source or the hot water is circulated along the heating pipe of the camper, When venting air, there is a limit to keeping the floor warm.

Japanese Patent Application No. 10-1773051 (heating apparatus of a camper car) supplies warm air to a room of a vehicle or a camping car by using an ignition heater mainly used in a camper car including a vehicle, A heating oil of a separate heating oil tank is heated by a burner and then supplied to the floor heating. The heated heating oil channel is heated to be used for a shower or a shower. It is.

However, since the heat medium reservoir tank in which the heat medium oil is to be filled must be provided separately and the heat medium oil is heated only by the burner, it is impossible to efficiently cope with changes in the place where it was moved and the climate and conditions. It circulates only the heat medium through the hot water panel, so that it can not efficiently cope with the change of the moved place, the climate and the situation.

Japanese Patent Application No. 10-1785571 (heating system of a camper car) is provided with a hot water tank for keeping the predetermined temperature by the heating means and replenishing the raw water, and a circulation pump connected to the hot water tank, A hot water supply unit for exchanging water with hot water heated by the hot water supplied by the supply pump after heat exchange with the hot water heated by the supply pump and a hot water supply unit connected to the hot water tank and circulating hot water circulated by the circulation pump, An indoor heating part for blowing air into the room by a blowing duct, and an operation part for controlling the floor heating part, the hot water supply part and the indoor heating part.

However, this means that the hot water tank must be installed separately, and the water in the hot water tank is frozen because it is left without running the camper in the winter season and the water of the hot water tank can not be utilized efficiently for heating. Water must be removed.
