Indoor heating in such a known motorhome can usually use a vehicle air conditioning system or provide a separate air conditioning system. In addition, in order to use hot water, it is common to install and use a water heater separately.

The present invention has the main technical idea to make not only the floor heating of the motorhome but also the heating of the room by using a single antifreeze tank.

The motorhome heating system 100 according to the present invention is the antifreeze tank 10 is maintained at a predetermined temperature by the heater (H) for burning fuel to generate heat energy, and the circulating pump (P) from the antifreeze tank (10) Cold water is heat-exchanged by hot water by the bottom heating part 20 which receives antifreeze of a predetermined temperature by driving and supplies it to the floor or the bed side of a motorhome, and the heat exchange part 31 which is located inside the antifreeze tank 10. The air heating unit 40 to supply the warm air to the interior of the camping car through the hot water supply unit 30 and the air heater 45 to generate heat by receiving the antifreeze of a predetermined temperature from the antifreeze tank 10 ), And a control unit 50 for controlling the driving of the heater (H), the floor heating unit 20, the hot water supply unit 30 and the air heating unit 40, the antifreeze tank 10 is Located in the lower side in the antifreeze tank 10 to the heater (H) The first antifreeze tank 11 receives heat and is disposed on the left or right side of the first antifreeze tank 11 in which the heat exchange part 31 of the hot water supply unit 30 is accommodated, and the first antifreeze solution through the partition plate 14. The second antifreeze tank 12, which is partitioned from the tank 11, and the upper side of the first antifreeze tank 11 is formed so as to be selectively communicated with the first antifreeze tank 11 through the opening and closing valve (V). It includes a third antifreeze tank 13, wherein the control unit 50 is a hot water mode driving unit 51 for hot water supply, a floor heating driving unit 52 for heating the floor, and an air heating driving unit for air heating (53).

Herein, the control unit 50 is provided with respective operation buttons corresponding to the hot water mode driving unit 51, the floor heating driving unit 52, and the air heating driving unit 53, and selected and operated according to the user's desired option. It is prepared to do so. Moreover, the said operation button can also be selected and used simultaneously.

The antifreeze in the antifreeze tank 10 may be controlled by a known method so that the heat of the heater H is directly supplied to maintain a set temperature. That is, the temperature of the antifreeze tank is provided for the purpose of providing floor heating, indoor heating or hot water, and is automatically controlled to maintain the predetermined temperature at all times. To this end, it is preferable to include a separate temperature sensor in the antifreeze tank 10 to adjust the driving of the heater (H) d in accordance with the sensed temperature so as to maintain a constant set temperature.

On the other hand, the antifreeze tank 10 does not have such a large volume, that is, because it has a limited space due to the characteristics of the motorhome, by making a relatively small volume, so as not to cause any obstacle to the space constraint. At this time, to have a small volume is not required so large volume by using the heating and hot water in a limited space, such as a motorhome. In particular, since the antifreeze tank 10 maintains the set temperature at all times, it is also possible to quickly provide desired heating or hot water when necessary, which is also one of the factors that can reduce the volume.

In the present invention, the antifreeze tank 10 is composed of a first antifreeze tank 11, a second antifreeze tank 12 and a third antifreeze tank 13, wherein the first antifreeze tank 11 is an antifreeze tank 10 The heat exchanger 31 of the hot water supply unit 30 is received at the lower side of the heater (H), and the second antifreeze tank 12 is the left or right side of the first antifreeze tank 11. The first antifreeze tank (11) is partitioned with the first antifreeze tank (11) through a partition plate (14), and the third antifreeze tank (13) is located on the upper side of the first antifreeze tank (11) through an open / close valve (V). It is formed to be selectively communicated with the first antifreeze tank (11).

Here, the first antifreeze tank 11 receives heat directly from the heater H, and the second antifreeze tank 12 is in a conductive form through a partition plate 14 partitioned from the first antifreeze tank 11. Get the heat.

In addition, the third antifreeze tank 13 is directly transferred by the first antifreeze tank 11 and the on-off valve V as the antifreeze is exchanged through convection with each other, so that heat is transferred.

The reason for separating the antifreeze tank 10 into the first antifreeze tank 11, the second antifreeze tank 12 and the third antifreeze tank 13 is to maximize the thermal efficiency according to the heating purpose of the user. For example, if only hot water supply is required, it takes considerable fuel and driving time to raise all of the antifreeze of the entire antifreeze tank 10 to the target temperature, but it is significantly reduced to increase only the antifreeze of the first antifreeze tank 11 to the target temperature. The amount of supplied fuel and the driving time are required.

Meanwhile, the floor heating unit 20 supplies hot antifreeze to the bed side or the bottom side of the motorhome through the first outlet 22 and the first recovery port 24 provided in the third antifreeze tank 13. The first outlet 22 and the first outlet 24 include a heating pipe 26 piped in a conventional manner to the bottom of the motorhome, which is in the form of a conventional closed loop.

If necessary, the heating pipe 26 may be divided into a needle pipe and a bottom pipe, the needle pipe may be connected to the second antifreeze tank 12, and the bottom pipe may be connected to the third antifreeze tank 13.

In this way, when the bed pipe and the bottom pipe are configured separately, the heat efficiency can be increased by not supplying heat to the bottom pipe when the user sleeps.

Thus, by heating the floor of the camper by the floor heating unit 20 has a condition that allows users familiar with the ondol culture to perform heating more comfortable and convenient to use.

In addition, due to the floor heating conditions are naturally made up to some indoor heating, that is, warming during floor heating can be naturally up to some of the room heating as the convection rises to the top.

On the other hand, the hot water supply unit 30 is provided in the first antifreeze tank 11 to be connected to one end of the heat exchange unit 31 and the heat exchanger 31 provided inside the first antifreeze tank 11 so that direct water flows in. It is connected to the other end of the direct water inlet 34 and the heat exchange unit 31 is provided with a hot water outlet 36 provided in the first antifreeze tank 11 to supply the heat exchanged. The hot water outlet is connected to the connection line of the shower or bath or washbasin provided in a conventional toilet or shower room and the like through a conventional distributor.

Here, the heat exchange part 31 is a form in which a plurality of heat exchange fins are mounted on a pipe manufactured in a coil form in which a normal direct water is circulated, or a direct water is circulated in a plate form, such as a conventional hot water heat exchanger provided in a known boiler. The heat exchange plate in which the passage is formed may be formed in a plurality of overlapping shapes.

Accordingly, the direct water flowing through the direct water inlet 34 is heat exchanged by hot water heated to the set temperature of the first antifreeze tank 11 in the course of circulating the heat exchange part 31, and the heat exchanged hot water is hot water. It is discharged through the discharge port 36. In this way, the hot water discharged through the hot water discharge port 36 is supplied to the place of use, that is, the shower or bath connected to the dispenser or the like can be used for the required purpose.

On the other hand, the floor heating unit 20 is supplied with antifreeze by the driving of the circulation pump (P) to supply the antifreeze of the third antifreeze tank 13, the hot water supply unit 30 is the user's hot water, such as wash basin or shower Hot water may be supplied by driving the valve, so a separate circulation pump may be omitted.

Meanwhile, the air heating unit 40 includes a second outlet 42 and a second recovery port 44 provided in the second antifreeze tank 12, and between the second outlet 42 and the second recovery port 44. The heat heater 45 for the hot water in the antifreeze tank 10 is circulated by the conventional circulation pump (P) and the heat generated by the air heater 45 in the rear of the air heater 45 is The heater is supplied to the circulation fan P to supply the warmer. The air heater has a known structure such as the heat exchanger described above, and is preferably installed in a housing or a frame in a set form with a blower fan.

Therefore, the air heating unit 40 may be made by using the antifreeze of the second antifreeze tank 12 provided for floor heating as described above, rather than by the air conditioning system of the conventional vehicle, thereby starting the vehicle. Indoor heating can be made smoothly even when turned off.

That is, the antifreeze circulated through the second outlet port generates heat in the process of passing through the air heater, and the warm air generated by the air is blown by a blowing fan provided at the rear of the air heater, thereby generating heat in the air heater. The warm air is blown to the circulation fan side.

Accordingly, the warm air blown through the circulation fan is to increase the indoor temperature in the camper can perform the indoor heating. At this time, when the floor heating is made, there is also a condition that can quickly increase the room temperature in the camper in a shorter time. In addition, indoor heating may be performed separately by the control unit 50 separately from the floor heating.

In addition, it is preferable to provide a conventional negative ion emitter or an air purifier on the front or rear surface of the second heat exchanger of the air heating unit so as to have a beneficial component or purification function in the indoor air together with hot air supply.

Thus, the present invention by using three compartments of the antifreeze tank can be made alone or in parallel to the floor heating of the motorhome with the hot water supply as well as hot water supply, it can be easily used in a limited space, such as a motorhome without additional equipment It can provide convenience.

Meanwhile, as described above, the control unit 50 includes a hot water mode driving unit 51 for supplying hot water, a floor heating driving unit 52 for floor heating, and an air heating driving unit 53 for air heating.

As described above, each driving unit may be driven at the same time as described above, but may be driven individually according to a user's selection, and the effect to be induced in the present invention may be maximized during the individual driving.

First, the hot water mode driving unit 51 supplies hot water to the first antifreeze tank 11 through the heat exchanger 31 so that the heater H is first driven when the hot water mode driving unit 51 of the control unit 50 is driven. A shut-off valve (V) for driving and connecting between the first antifreeze tank (11) and the third antifreeze tank (13), and the heat exchange part (31) in the first antifreeze tank (11) through the hot water supply (30). It is configured to discharge the hot water heat exchanged by.

Of course, when the user operates the hot water mode driving unit 51 and the floor heating driving unit 52 at the same time, the opening and closing valve (V) is opened.

When the user selects only the hot water mode driving unit 51 as described above, the heat transferred from the heater H is required only to increase the temperature of the antifreeze in the first antifreeze tank 11, so that the second antifreeze tank 12 and the third antifreeze solution are used. The antifreeze in the tank 13 will be maintained at a temperature lower than or near room temperature than the first antifreeze tank 11.

That is, the antifreeze of the second antifreeze tank 12 receives heat in a conductive form through the partition plate 14 to have a temperature lower than that of the first antifreeze tank 11 but higher than room temperature, and the third antifreeze tank 13 In the case of), as the shut-off valve (V) is closed, almost no heat is supplied to maintain a temperature close to room temperature.

Since only the antifreeze contained in the first antifreeze tank 11 needs to be raised to a target temperature when the hot water mode driving unit 51 is driven only, the amount of fuel supplied and the time of arrival are also reduced.

On the other hand, the floor heating driving unit 52 is provided to supply antifreeze to the bed side or the bottom side, when the user selects the floor heating driving unit 52, the control unit 50 drives the heater (H) and the first The on-off valve V connecting the antifreeze tank 11 and the third antifreeze tank 13 is opened, and the antifreeze in the third antifreeze tank 13 is supplied to the bottom or the bed side of the motorhome through the circulation pump P. It is configured to be.

As described above, when the floor heating driving unit 52 is separated into the bottom pipe and the bed pipe, the floor heating driving part 52 is separated into the bottom pipe driving part 52a and the bed pipe driving part 52b, and the bottom pipe is the third antifreeze solution. It is connected to the tank 13 is supplied with antifreeze and the needle pipe is connected to the second antifreeze tank 12 will be configured to receive the antifreeze.

This is advantageous for the user to increase the thermal efficiency when going to bed, and as the antifreeze is supplied to the needle passage along with the air supply unit 40 connected to the second antifreeze tank 12, heating is separately performed without the heat supply of the third antifreeze tank 13. It can be made is that the thermal efficiency is increased.

On the other hand, the air heating and driving unit 53 is configured to supply the warm air in the camper receives the antifreeze from the second antifreeze tank 12, when the user selects the air heating and driving unit 53, the control unit 50 is Air heater for driving the heater (H) and closing the opening and closing valve (V) for connecting between the first antifreeze tank (11) and the third antifreeze tank (13), and receives the antifreeze from the second antifreeze tank (12) It is configured to supply warm air to the interior of the motorhome through 45.

In this way, the user needs only the supply of hot water, or by reducing the amount of antifreeze to increase the temperature through heat supply at bedtime can significantly increase the thermal efficiency.

As described above, the present invention has been described with reference to one embodiment shown in the drawings, but this is merely an example, and those skilled in the art may realize various modifications and other equivalent embodiments therefrom. I will understand.
