Description

Heating and Hot-Water Supply Divice in Caravan and Control Method of thereof

The present invention relates to a heating and hot water supply system for a mobile lodging facility such as a caravan.

More specifically, a heat exchanger is mounted on the heat source of the heater with a warm air function, and circulating water heated in the heat exchanger is supplied to each device to enable floor heating and hot water mat heating, and additionally connect a heat exchanger using the circulating water as a medium. It relates to an apparatus for producing and supplying hot water and a method for controlling the same.

Recently, due to the spread of various leisure cultures, the use of campers, caravans, etc. has increased, and the industry such as import sales and production is steadily growing.

As a result, the caravan heating industry is also developing, but unlike European users, Korea is accustomed to the ondol culture, so it is time to develop a new heating technology for the ondol method.

In general, a camping car is a car made for cooking and lodging during long-distance travel and long-distance travel, and consists of an engine part in the front and a living space part in the back.

Also, a caravan is a mobile home that can be dragged and hung from a car.

As shown in Fig. 1, the indoor structure is by installing living facilities such as a kitchen faucet (4), a bed (2), a toilet/table/conversion bed (3), a gas heater body for heating (10), and a transfer hose (16). Cooking and lodging are also available.

Its interior structure is similar except for the engine part of the camper, and features lightness, mobility, and convenience.

Due to the similarity of such structures, in the present invention, a caravan is described as an example, but it can be applied to a camper, furthermore, a truck that travels a long distance and simply stays there.

In these caravans, energy sources such as storage batteries, LPG gas (hereinafter gas), and liquid fuel are used. Among them, storage batteries are mainly used for electric appliances such as electric lamps and TVs, and gas and liquid fuels are also used for cooking and refrigerators, and in particular, they are mainly used as energy for heating devices.

Heating devices using gas and liquid fuel have already been distributed through many technological developments, and their names are called gas heaters that use gas or non-rechargeable copper heaters that use diesel (liquid fuel) depending on the fuel used.

Two heaters are installed inside and outside the caravan to heat the surrounding air using the combustion heat of fuel to heat the interior of the caravan by direct heating method of conduction, radiation, or convection or the warm air heating method using a blower fan. Because the structure and method are similar, it is usually referred to as a heater.

In the caravan, gas heaters are well equipped for cooking and have excellent thermal efficiency, so in the present invention, examples are shown based on gas heaters.

The structure of commercial gas heaters for caravans (hereafter heaters) is generally

As shown in FIG. 2 , the hot air sending unit 13 installed on one side of the caravan and blowing warm air into the caravan interior through the transfer hose 16 on the rear side, the heat dissipation body 11 installed inside the housing, and its heat dissipation It surrounds the outside of the body and is composed of a heat dissipation fin (12) protruding outward, a thermal power controller (14), and a blower controller (17).

The heat dissipation body 11 serves as an outer wall of the combustion chamber that burns the gas fuel introduced from the lower end of the combustion chamber and discharges the combustion gas to the outside through the exhaust hose at the upper end of the combustion chamber. make it possible,

Radiating fins have a role of radiating and conducting heat from the heat dissipation body into the air. There are several types, but in general, to increase the conduction efficiency, they protrude to the outside and form a thin fin. It may protrude more to the outside or only protrude from the top to be installed. In addition, a plurality of heat dissipation fins are formed at regular intervals and most have a vertical structure for smooth convection of heating air. The blower is installed on the front or side part of the method that directly sends heated air into the caravan, and installed on the rear part of the housing when sending it through a transfer hose to forcibly convect the heated air into the room.

The thermal power controller 14 is a device that mechanically and electrically controls the amount of fuel flowing into the combustion chamber to regulate the heat of combustion, that is, the amount of heat generated. The indoor heating temperature is being adjusted.

The heating power regulator and the blow regulator of commercial product heaters have slightly different operation methods for each manufacturer, so the control method of the thermal power regulator and the blow regulator is not provided in the present invention.

In addition, as a floor heating technology, heating the floor using heating water (hereinafter referred to as circulating water) is efficient, and indoor heating in a caravan using circulation water can be divided into two types. I will divide it into heating using a hot water mat that is easily installed and attached on the mattress of the conversion bed.

Many commercial products for residential use have been developed for floor heating panels, and they can also be used in caravans. For semi-permanent use, the heating pipe is fixed on the indoor floor and the circulating water heated from the heat source is circulated to the heating exhaust hose with the transfer power of the circulation pump to be heated.

In consideration of its efficiency and durability, hard and thin pipes are installed and used.

The hot water mat is a heating device that has a hot water hose built into the mat, and is also a heating device developed to circulate water heated from a heat source to the hot water hose with the transfer power of the circulation pump.

A small, thin, soft hose is used for the convenience of detachment and storage.

In addition, the hot water supply device uses hot water by installing a gas water heater or an electric water heater, and the technology is a device that uses water heated from a heat source as the transfer power of a pump directly or by using a heat exchanger to heat cold water.

Since the heating and hot water supply devices are devices that use the power of a pump or a fan to heat air or water using a heat source, development of a device capable of using a single heat source is being attempted.

However, there are also several limitations and problems in using one heat source.

Prior art [Document 1] A heating device for a caravan capable of supplying hot air and heating the floor

Looking at KR 10-1910928, etc.

Even if the user wants only the warm air function, the heat pipe will be heated due to the heat of the heater heating part, and the heating water will also be heated. If the circulation pump is not driven in this state, the circulating water is heated above the boiling point and cuts off, which can lead to damage to the heating hose, machine failure due to the spout of heating water, as well as a user safety accident. For that reason, it is necessary to operate the circulation pump to heat the floor unintentionally by the user, which will lead to unnecessary energy wastage.

In addition, even when the heating temperature rises above a certain temperature and the supply of circulating water is no longer needed, the circulating water cannot be shut off, so it is difficult to control the temperature maintenance.

As such, there are prior technologies for heating and hot water supply using a single heat source, but it is impossible to use alone or operates unnecessary functions contrary to the user's intention, thereby having difficulties in energy loss and temperature maintenance control.

In addition, there are problems such as frequent breakdown, short lifespan, and noise generation due to continuous use of the circulation pump because there is no method for controlling the stop of the circulation pump.

In addition, as the heating area increases due to the increase in the size of the caravan, more heating energy is required, so it is necessary to develop a heat exchange device with more efficient heat transfer performance.

In addition, the heating pipe used in the floor heating panel and the hot water hose of the hot water mat used in the bed and the conversion bed have different sizes and lengths, and the temperature control and temperature of each device in the caravan room where the temperature difference by location is large depending on the external environment. A maintenance control method is required.

In addition, in most cases where water is used as heating water, machine damage and repair costs occur due to freezing in winter, and even when antifreeze is used to prevent freezing, the toxicity and flammability of antifreeze cause safety problems, and in particular, circulation due to high viscosity of antifreeze New technology development is required to solve these problems, such as a problem that the lifespan of the pump is significantly reduced.

In addition, the accessory equipment of the supply device is a heat exchanger, hot water mat. Sea heating panel, hot water mat temperature control unit, hot water tank, hot water tank temperature sensor unit, heat exchanger for hot water. includes a control unit.

The heat exchanger is composed of an inner pipe which is in contact with the heating body and formed side by side with a heating fin therebetween, and an outer pipe formed side by side with the heating body at a predetermined interval, so that the largest area is in contact with the heating part and the primary, outer side of the inner pipe It can have high-efficiency heat transfer performance by heating the circulating water through the second two rounds in the pipe.

Also, due to the convection phenomenon due to thermal expansion, the upward force generated in the inner pipe is much larger than the upward force generated in the outer pipe, so that the circulating water can move from the inner pipe to the outer pipe. That is, the circulating water can be naturally transferred from the inlet to the outlet.

In addition, the hot water mat temperature control unit may have an input unit for receiving a user's setting value and an output unit for outputting the sensed temperature value, etc., and is interlocked with the following control unit and is conveniently installed in a short distance for the user to operate or can be manufactured in the form of a wireless terminal have.

The hot water tank may receive cold water, produce and store hot water through heat exchange with the hot water heat exchanger, and supply it back to the faucet, and may be equipped with a hot water tank temperature sensor for sensing the temperature of the stored hot water.

The hot water heat exchanger may serve to produce hot water by exchanging the thermal energy of the circulating water with the hot water of the hot water tank.

The hot water mat and the floor heating panel can heat the bed or the floor by circulating circulating water through an internal hose.

In addition, the control unit may be composed of an input unit and an output unit, and by collecting and processing the values of the input unit and each sensor unit, it is possible to control the operation of the circulation pump unit and the water discharge pump and the opening and closing of each solenoid valve.

On the other hand, the control method of the heating and hot water supply device for performing single use and simultaneous use of each function and individual temperature control among the above tasks is provided as follows.

So that the circulating water heated to the heat exchanger can be supplied to the device, the control unit receives an on/off selection input for activating the hot water mat function, the floor heating function, and the hot water function from the input unit, and opens and controls the solenoid valve corresponding to the on input function. Circulating water can be supplied.

On the other hand, the solenoid valve corresponding to the off-input function can be controlled to close to cut off the supply of circulating water.

In addition, the control unit controls the initial speed of the circulation pump by dividing the operation mode according to the initial on/off input, and the bypass solenoid valve can be closed.

In addition, the control unit receives the temperature set value of the device desired by the user from the input unit, and when the value detected by the sensing unit reaches the set value, the control unit closes and controls the solenoid valve to cut off the supply of circulating water, and again the detected value is set below the set value. When the temperature goes down, the process of supplying circulating water can be performed by controlling the opening of the solenoid valve.

By repeating the above process, the user can maintain and control the desired temperature.

In addition, the control unit analyzes the type of circulating water supplied to each device and analyzes the type of circulating water supplied to each device, taking into account only the case in which the temperature sensing value of each sensor reaches the set value and there is a change in whether circulating water is supplied to each device and the circulating water is supplied to each device. The rotation speed of the motor can be controlled at a preset speed, and the bypass solenoid valve can be opened and closed according to the type.

In particular, in the case of a type in which the supply of circulating water to all devices is cut off because the corresponding detected values of the on-input functions have all reached the set value among those types, the circulation pump is stopped and the bypass solenoid valve is opened to control the opening of the heat exchanger. With the natural transfer function of the circulating water, it is possible to directly pass the circulating water from the supply distributor to the recovery distributor.

In addition, in order to use the warm air exclusive function, by turning off the hot water mat function, the floor heating function, and the hot water function, it is possible to control the circulating water not to be supplied to the heating device or hot water device. By moving from the supply distributor to the recovery distributor, the warm air function of the heater can be used alone.

Through the above control method, single use and simultaneous use of the hot air function, the hot water mat function, the floor heating function, and the hot water function are possible, and the temperature maintenance control for each function is also possible.

In addition, in order to prevent freezing of the circulating water in winter among the above tasks, the water outlet is provided in the supply device,

The drain part can be divided into both the drain hose and the recovery hose using the drain distributor.

The discharge hose on one side is equipped with a discharge solenoid valve 91, a discharge pump 92, and a discharge hose 93, so that the circulating water can be discharged to the outside under the control of the control unit.

On the other side of the recovery hose, it would be desirable to have a third check valve mounted on the part adjacent to the waste water distributor, and the end connected to the water storage unit so that the circulating water is recovered.

According to the invention

Using a single heat source, the hot air function, the hot water mat heating function, the floor panel heating function, and the hot water function can be used alone or at the same time to reduce the manufacturing cost, energy saving effect, and the heat exchanger can naturally transfer the circulating water, which is why the circulation pump Because stop control is possible, it can have effects such as extending the life of the circulation pump, reducing maintenance and management costs, and reducing noise.

6 is a schematic view of an embodiment of the vertical heat exchanger of the present invention.

(A) is a schematic diagram of the structure of a vertical heat exchanger,

(B) is an enlarged view of the heating fin 12 and the heat exchanger 15 .

With reference to FIG. 6 , the high-efficiency heat transfer characteristics through the structural shape of the vertical heat exchanger according to the embodiment of the present invention will be described in detail as follows.

A straight pipe 151 formed vertically upward in contact with the heating body 11 is gently bent toward the outside of the heating body 11 and extended to a straight pipe 152 in a right oblique downward direction, and the pipe 152 is It is gently bent toward the inside of the heating body and formed to extend into a straight pipe 153 of a vertical upward direction, and the pipe 153 is gently bent toward the outside of the heating body and is formed to extend into a straight pipe 154 in the downward direction oblique to the right. By repeating this several times, a plurality will be formed.

In addition, the pipe 151 and the pipe 153 (hereinafter, the inner pipe) are formed with the heating fin 121 interposed therebetween, and the pipe 153 and the pipe 155 are formed side by side with the adjacent heating fin 122 interposed therebetween.

The circulation pump unit 30 is stopped and there is no action of external force, and the circulating water is heated by the heat of the heater 10 heating unit.

In the inner pipe 151 , the circulating water exerts an upward force to move from the lower part 1511 to the upper part 1512 as a convection phenomenon due to thermal expansion. In addition, the circulating water of the outer pipe 152 acts as a convection phenomenon due to thermal expansion, which causes a rising force to move from the lower part 1521 to the upper part 1522 .

Since the inner pipe 151 receives much more heat from the heater than the outer pipe 152 , the inner pipe ascending force acts much larger than the outer pipe ascending force.

Therefore, the circulating water naturally moves from the inner pipe 151 to the outer pipe 152, and ultimately the flow of circulating water flows from the inlet 150 to the pipe 151, the pipe 152, the pipe 153, the pipe 154. ) is passed sequentially and moved to the water outlet (159).

As a result, the heat exchanger 15 can naturally transfer the circulating water from the first connection part 33 to the second connection part 35 in the stopped state of the circulation pump part 30, which uses a low-power circulation pump to convert the circulating water. It will also have the advantage of being able to supply it to each device.

8 is a schematic diagram of a horizontal heat exchanger according to another embodiment of the present invention;

(A) is a schematic diagram of the structure of a horizontal heat exchanger.

In the horizontal type heat exchanger, a straight pipe 161 that is in contact with the heating body 11 and has a predetermined inclination in the horizontal direction is gently bent toward the outside of the heating body, and has a predetermined inclination in the horizontal direction. The pipe 162 is formed to extend into the pipe 162, and the pipe 162 is gently bent toward the inside of the heating body 11, has a predetermined inclination from the horizontal, and is formed to extend into a straight pipe 163 directed upward to the left, and the pipe 163 is gently bent toward the outside of the heating body and extends from the horizontal to the right-upward straight pipe 164 with a predetermined inclination, and by repeating this several times, a plurality of will be formed.

That is, a plurality of inner pipes are formed side by side in contact with the heating body and adjacent to each other with the heating fins interposed therebetween.

In addition, a plurality of outer pipes will be formed side by side with the heating body 11 and a predetermined interval therebetween.

In another embodiment of the present invention, the horizontal heat exchanger can also install a larger number of inner and outer pipes in the heating part of a certain area,

In addition, since the circulating water is heated first in the inner pipe and secondarily in the outer pipe, it can be heated twice, so it has high-efficiency heat transfer characteristics compared to the heat exchanger developed previously.

FIG. 8(B) is a diagram schematically showing the action of a force in a vertical heat exchanger.

When described with reference to FIG. 8 (B)

In the inner pipe 161, a rising force acts due to a convection phenomenon due to thermal expansion.

Also in the outer pipe 162, a rising force is added due to the convection phenomenon due to thermal expansion, so that the circulating water can be naturally transferred from the inner pipe 161 to the outer pipe 162, which can be naturally transferred from the inlet to the outlet. That is, the circulating water can be naturally transferred from the first connection part to the second connection part.

The vertical heat exchanger and the horizontal heat exchanger of the above embodiment can reduce the use time of the circulation pump because the circulation pump can naturally transfer the circulating water while the circulation pump is stopped, and the circulation pump can smoothly circulate the circulating water under low power, thereby reducing noise. It can have the effect of reducing, prolonging machine life, and reducing cost.

In the above embodiment, examples of vertical and horizontal heat exchangers have been described, but it is believed that various modifications or variations of the shape are possible without departing from the spirit of the present invention, which will be included in the claims below.

In addition, the accessory hot water mat temperature controller 72 can be interlocked with the input and output units of the control unit, and the on/off of the hot water mat function, the input unit for inputting the user's desired temperature set value, use time, etc. and outputting the sensed value, etc. It can have an output unit and can be manufactured in the form of a wall or wireless terminal close to the user.

In addition, the attached equipment hot water mat 51, the floor heating panel 53, the hot water heat exchanger 55, the hot water tank 57, the hot water pump 59 is the use of well-known commercial products, detailed description is omitted.

In addition, the accessory control unit 70 may be installed alone on the upper surface of the main body 100 or the inner wall surface of the caravan, or installed in conjunction with the main controller of the caravan.

In addition, the control unit 70 may have an input unit for inputting on/off selection of each function, setting of a desired temperature, and use time, and an output unit for outputting the received information or the current state of the supply device.

In addition, the control unit analyzes the set temperature of each function input from the user through the input unit, on/off selection, hot water mat, floor heating, and hot water and the data obtained from each sensing unit, and the circulation pump unit 30 is preset. It controls to rotate at a speed and controls the opening and closing of the corresponding solenoid valve to control the supply and blocking of the circulating water to the device.

The control method of the heating and hot water supply apparatus of the present invention will be described in detail as follows.

In the following description, the solenoid valve of each function (device), the temperature sensing unit, and the corresponding set value refer to devices directly related to the device to execute the function.

For example, in the case of a hot water mat heating function (device), it refers to the first solenoid valve 42 and the fifth solenoid valve 82 , the hot water mat temperature sensing unit 71 , and the hot water mat temperature set value.

Continuing the description of the control method of the present invention

9 is a flowchart schematically illustrating the control method of the present invention.

The heat source and hot air function of the heater are controlled by a separate control method by the user, and the heater is in operation.

Referring to FIG. 9

The control unit 70 may receive an on/off selection input for operating the hot water mat heating function, the floor heating function, and the hot water function from the input unit ( 200 ).

The control unit 70 can open and control the solenoid valve corresponding to the on-input function,

The solenoid valve corresponding to the function inputted off can be controlled to close. (220)

The control unit 70 divides the initial operation mode according to whether each function is on or off (400),

According to the initial operation mode, the circulation pump unit 30 can be controlled to be driven at a preset rotation speed (the following initial speed control) (420)

In addition, the control unit 70 may open/close the bypass hose solenoid valve 48 according to the initial operation mode. (The following initial opening/closing control) (440)

The control unit 70 may receive the temperature set value of each function from the input unit. (240)

When the temperature sensing value corresponding to the on-input function reaches the set value (300), the control unit 70 can control the closing of the solenoid valve. (320)

The on/off selection input 200 and the corresponding temperature detection value reach the corresponding set value (300)

As a result, the closing control of the solenoid valve is controlled (320), and there is a change in whether circulating water is supplied to each device, so by analyzing the type of circulating water supplied to the device (800)

Depending on the type, the rotation speed of the circulation pump unit 30 can be controlled at a preset speed (the following operation speed control). (820)

Depending on the type, it is possible to control the opening and closing of the bypass solenoid valve valve (48). (The following operation opening/closing control) (840)

When the initial operation mode division 400, the initial speed control step 420, and the initial open/close control step 440 are described in detail,

As each function is selected on or off, hot water mat single mode, floor heating single mode, hot water exclusive mode, hot water mat-floor heating simultaneous mode, floor heating-hot water simultaneous mode, hot water-hot water mat simultaneous mode, hot water mat-floor heating - Hot water simultaneous mode; It will be divided into a total of 7 initial operation modes as shown below. (400)

The initial rotation speed of the circulation pump may be controlled by presetting the rotation speed value of the circulation pump unit 30 for each mode. (420), for reference, to adjust the rotation speed of the circulation pump will be to adjust the DC voltage.

For example, speed A (DC 6V) in hot water mat alone mode, speed A (DC 6V) in floor heating independent mode, speed A (DC 6V) in hot water single mode,

Hot water mat -Speed B (DC 9V) for floor heating simultaneous mode, Floor heating-Speed B (DC 9V) for hot water simultaneous mode, Speed B (DC 9V) for hot water -hot water mat simultaneous mode

In the hot water mat-floor heating-hot water simultaneous mode, the circulation pump unit 30 is set to rotate by specifying the speed C (DC12V)).

In addition, the bypass hose solenoid valve 48 can be controlled to be closed in all of the seven initial operation modes (440).

In addition, when the circulating water supply type analysis 800 , the operation speed control step 820 , and the open/close control step 840 during operation are described in detail,

As circulating water is supplied among the devices that are initially turned on, the sensing value of the sensing unit reaches the set value, and the solenoid valve closes and the supply of circulating water is cut off. There will be cases in which circulating water is continuously supplied because it does not reach the To control the pass solenoid valve (48).

The types in which circulating water is supplied to each device are the hot water mat alone supply type; floor heating sole supply type; hot water sole supply type; Hot water mat - floor heating simultaneous supply type; floor heating and hot water simultaneous supply type; hot water - hot water mat simultaneous supply type; Hot water mat-floor heating-hot water simultaneous supply type;

It will be divided into a total of 8 types, including 7 types such as etc. and a completely closed type in which circulating water is not supplied to all equipment. (800)

The operation speed of the circulation pump can be controlled by presetting the rotation speed value of the circulation pump unit 30 for each supply type. (820)

As an example, the 7 supply types are similar to the initial operation mode (there is only a temperature difference of the circulating water) and can be set to the same value as the set value of the initial operation mode.

In the case of hot water mat single supply type, floor heating sole supply type, hot water single supply type, the hot water mat - floor heating simultaneous supply type, floor heating, - hot water supply type, hot water - hot water mat simultaneous supply type at speed A (DC6V) In case of speed B (DC9V), in case of simultaneous supply of hot water mat-floor heating-hot water, it is set to speed C (DC 12V).

In addition, the completely closed type can stop the circulation pump (speed = 0), and as another example, consider the frictional resistance of the bypass hose, the viscous resistance of the circulating water, and the pressure loss according to the length of the hose. ) can also be specified.

In addition, the bypass hose solenoid valve 48 can be controlled to open in the completely closed type, and to be controlled to close in the remaining 7 types.

By using the speed set value for each initial operation mode and the speed set value for each type of supply of circulating water during operation,

An example of an operation will be described.

If the user selects the hot water mat function and hot water function on the input part,

The corresponding solenoid valves 1 and 5 (42, 82) for the hot water mat function and the 3 and 7 solenoid valves (46, 86) for the hot water function are controlled to open, and the circulating water is supplied to the hot water mat and the hot water heat exchanger. The second and fourth solenoid valves 44 and 84 of the corresponding solenoid valves of the floor heating function that have been turned off are controlled to close, so that circulating water is not supplied to the floor heating panel.

Since the initial operation mode is a hot water mat-hot water function simultaneous mode, the circulation pump unit 30 rotates at a specified speed B (DC9V) and supplies circulating water to the hot water mat and the hot water heat exchanger to perform the hot water mat heating function and the hot water function. . Also, the bypass solenoid valve valve 48 is closed.

As the circulating water is supplied, the temperature of the hot water mat and hot water rises gradually. First, when the temperature detection value of the hot water mat sensor reaches the set value, the 1st and 5th solenoid valves 42 and 82 are closed to supply the circulating water to the hot water mat. Shut off the supply so that the temperature of the hot water mat does not rise any further.

In addition, the circulating water is not supplied to the hot water mat and is supplied only to the hot water heat exchanger. That is, it is converted to a hot water single supply type, and the circulation pump unit 30 is adjusted and controlled at a set speed A (DC6V).

Thereafter, when the detected value of the hot water sensor 75 of the hot water tank 57 also reaches the set value, the third and seventh solenoid valves 46 and 86 are also closed to block the supply of circulating water.

Now, it is a completely closed type in which circulating water is not supplied to all devices, so the circulation pump unit 30 is controlled to stop and the bypass solenoid valve 48 is controlled to open, so that the circulating water through the bypass hose 50 is returned from the supply distributor to the distributor will pass directly through

Thereafter, when the temperature sensed value of the hot water mat sensing unit 71 of the hot water mat 51 is lower than the set value by a specified temperature, the 1.5 solenoid valves 42 and 82 are opened and controlled to supply circulating water to the hot water mat. Now, the circulating water supply type becomes the hot water mat alone supply type, and the circulation pump unit 30 rotates at a specified speed A (DC 6V) to supply circulating water to the hot water mat 51 , and the bypass solenoid valve 48 is It is controlled to close so that the discharge pressure of the circulation pump unit 30 is not lost. Afterwards, when the temperature sensing value of the hot water sensing unit 75 goes down by a specified temperature than the set value, the 3 and 7 solenoid valves 46 and 86 are opened to resume supply of circulating water, and the circulation pump unit 30 operates at a speed B ( DC 9V) and the bypass solenoid valve 48 maintains closed control.

The control unit repeats the control process to maintain the temperature of the hot water mat and hot water, and performs a heating function and a hot water function.

As can be seen from the examples of the present invention in this way,

In the control method of the present invention, only the corresponding solenoid valve is opened by selecting the on/off input of each function to operate the corresponding function, and when the corresponding detected value reaches the corresponding set value, the corresponding solenoid valve is closed to cut off the supply of circulating water to maintain the temperature When all of the solenoid valves are shut off when the corresponding detection value reaches the set value, the bypass solenoid valve 48 is opened and the circulating water is circulated through the bypass hose 50, thereby providing hot water mat, floor heating, and hot water function. It can be used alone and at the same time, and the temperature maintenance control for each device is possible.

In addition, by turning off the hot water mat, floor heating, and hot water functions, the circulating water directly passes through the bypass hose 50, so that the warm air function of the heater can be used alone.

In the present invention, the water discharge control method will be described by way of example.

The control unit 70 may control the opening of the water discharge solenoid 91 , the operation of the water discharge pump 92 , and the operation of the circulation pump unit 30 to the water discharge input of the input unit.

The control unit 70 opens the first and fifth solenoid valves 42 and 82 and closes and closes the second, 3, 6, and 7 solenoid valves 44, 46, 84, 86 and the bypass solenoid valve 48. and after a predetermined time has elapsed

The control unit 70 can open the second and sixth solenoid valves 44 and 84 and control the closing of the first, 3, 5, 7 solenoid valves 42, 46, 82, 86 and the bypass solenoid valve 48, After a predetermined time has elapsed

The control unit 70 opens the third and seventh solenoid valves 46 and 86 and closes and closes the first, second, fifth, and sixth solenoid valves 42, 44, 82, 84 and the bypass solenoid valve 48. and after a predetermined time has elapsed

After a predetermined time has elapsed

The control unit 70 closes the water discharge solenoid valve 48 and the water discharge pump 92 . The circulation pump unit 30 can be controlled to stop.
