The case 100 and the supplementary water tank 230 which is opened and closed as a stopper to the outside of the case 100 are connected to the upper side as a water replenishment connecting channel and directly connected to the water flowing in the hot water circulation pipe 110. Heater 220 is built-in to enable heating and heating to obtain high temperature hot water in a short time, and on one side is equipped with a heater temperature sensor 210 and at the same time A heating unit 200 having a water exit temperature sensor 240 at the exit side; In order to circulate the heated hot water, the heating unit 200 is provided with a hot water recovery pipe and a hot water discharge pipe connected integrally with the hot water circulation pipe path 110, so that one side of the hot water circulation pipe path 110 can effectively dissipate heat. The heat radiating pipe 110a, which is rounded and folded in a predetermined shape, is divided into a predetermined space, and the heat radiator 300 having an upper temperature sensor 310, a central temperature sensor 320, and a lower temperature sensor 330 disposed at a predetermined portion. )Wow; The controller 400 is connected to the temperature sensors 210, 310, 320, 330 in a line, and receives a sensed value to selectively control the heater 220, the circulation pump 120, and the blower pen 130 according to an operating state. .

Further, the water extraction temperature sensor 240 is to control the speed of the circulation pump 120 to maintain the hot water flowing out of the heating unit 200 at the programmed temperature, the upper temperature sensor 310 is the temperature of the discharged hot air In order to control the proportional control operation of the heater 220, the central temperature sensor 320 detects a constant temperature of the blowing to control the driving and stopping of the blower pen 130 at the time of initial operation and stop. The lower sensor 330 is configured of a controller 400 programmed to detect the temperature of the inflow wind temperature and at the same time detect the room temperature to turn on / off the heater 220. It is configured to receive the temperature value of the temperature sensor 310 to supply only the minimum power required to the heater 220 according to the programmed temperature to maintain the desired discharge hot air temperature.

Furthermore, the control unit 400 is configured to enable a reservation operation and a reservation stop by installing a clock, and at the same time, includes a temperature control unit, a humidity and CO ₂ alarm function, a room temperature display window, a water supplement display window, as well as a heater disconnection. It consists of an error detection circuit to detect an error mode such as a short circuit, a circulating pump overload, and a sensor disconnection.

Here, the heater 200 which directly heats the heating water is formed with a spiral jaw 210 protruding at a predetermined length along the outer circumference of the heater 200 so that the heating water is heated in a helical flow in a short time. As long as the water is heated directly to the heater 200, means for forming various structures and shapes can be mobilized. For example, when the unit boiler unit 100 is changed to any one shape such as square, rectangle, hexagon, etc., the heater 200 is also changed to suit the shape.

In addition, the shape and size of the case 100 of the heater is to vary the size and shape according to the warm air area and capacity, which can be configured to have a wheel on the lower side for easy movement, the heat pipe 110a By further expanding or expanding the thermal contact area of the circulating hot water, not only the hot air from the radiator 300 can be generated more easily and quickly, but also selectively provided with a plurality of heating units 200 that heat the water. It is possible to easily heat up the temperature to a high temperature within a short time and each heated hot water and steam is combined with one of the hot water outflow main discharged from the tubing of each heating unit 200 of the hot water and steam formed It can be applied to increase the amount.

In the present invention configured as described above, first, when the power is turned on, the circulating pump 120 starts low-speed operation (60 rpm) and at the same time the heater 220 starts 300 W operating heat, and the water spirals in the heating unit 200. Direct heating is performed in a short time while circulating to the hot water circulating pipe 110, and at this time, the central temperature sensor 320 detects an initial temperature in the radiator 300 and transmits the initial temperature to the controller 400. ) Stops the blower pen 130 motor until reaching the programmed temperature (about 45 ℃) based on this value, and drives the blower pen 130 motor when reaching 45 ℃ to prevent the initial cold air divergence And the initial operation to achieve the warm air generation time in a short time is performed.

Then, when the warm air is emitted into the room, the upper temperature sensor 310 detects the discharged warm air temperature and transmits it to the control unit 400, and the control unit 400 reaches the programmed temperature (about 80 ° C.) based on this value. At the time, the power supplied to the heater 220 is sequentially controlled (300W--200W--100W) while maintaining the warm air temperature (approximately 80 ° C.) while flexibly adjusting the power supply to perform ultra low power operation and at the same time indoors. Medium-term operation is performed to provide efficient and stable heating. At this time, the hot water is discharged from the heating unit 200 to maintain a constant temperature (temperature that does not sublimate into steam while dissipating heat) to the outlet water temperature sensor 240 detects the outflow temperature of the circulation pump 120 By selectively increasing or decreasing the speed, the hot water is circulated while maintaining a constant temperature.

Thereafter, the set temperature input to the controller 400 by the user is sensed by the lower sensor 330 and transmitted to the controller 400, and the controller 400 turns off the heater 220 based on this value to operate the heater. At this time, the blower pen 130 continues to drive until the detected value of the central sensor 320 falls below a programmed temperature (about 45 ° C.) to maximize the heating efficiency. Done.

When the temperature falls below the set temperature, the above-described initial operation, intermediate operation, and target temperature operation are repeatedly performed.

On the other hand, the control unit 400 has been found to include an error detection circuit to display the error mode by detecting a signal such as heater disconnection, leakage, circulating pump overload, sensor disconnection. For this purpose, a circuit that can detect current and voltage on the line is added to the measurement position (side where current is input to each equipment), and the detected signal value and the signal value in the normal mode are compared and analyzed, and each load is circulated. By checking the status of pumps, heaters, sensors, and short circuits at all times and displaying a warning sound on the display when an error occurs, the user can take immediate and prompt first aid measures to prevent power leakage and equipment malfunction. By doing so, it is possible to continue the ultra-low power heating operation.

Furthermore, by connecting the control unit 400, which determines whether there is an abnormality of the electric heater, with a computer, it is possible to more accurately diagnose the condition of the facility using a diagnostic program, etc., and at the same time, configure a heater subsidiary program to automatically input the detected input value. It is also possible to efficiently manage the radiator by making it possible, and this consumer computer is configured to be connected to the producer computer using a network, which is an internet network. By predicting the possibility of failure of the equipment, it is possible to replace the old equipment in a timely manner so as to provide higher quality service to consumers.

On the other hand, in driving the electric heater of the present invention, it can be driven by an external control system using a remote control, such as the role of home automation, for example, the detection of gas leakage or fire occurrence and intrusion of outsiders can be detected. Functions can be added, and furthermore, it can be equipped with alarm function, audio function, telephone, and interphone function at the same time. In addition, it is also revealed that the function of the electric heater can be further improved when the controller is manufactured so that the temperature setting and home auto function search can be performed through the mobile phone in the external setting mode.

Furthermore, by turning off the boiler, the operating time and room temperature can be executed in the boiler itself by a reservation program, and the operating program can be connected to a network to realize the boiler operation over the Internet.
