As described above, in the conventional hot water-combined electric boiler, the diameter of the heating pipe is small and the water circulation inducing protrusion is formed in the heating pipe, so that the water is moved in a spiral manner, thereby maximizing the contact between the heater and the water.

However, the conventional hot water boiler has a problem in that it takes much time to form a helical water circulation inducing projection along the inner circumferential surface of the heating pipe because the workability is low.

In addition, when the heating rod of the heater is installed inside the heating tube, water is brought into contact with the heating rod, and the flow or vibration of the heating rod is generated by the friction, thereby shortening the lifetime of the heating rod.

Further, after the use of the conventional hot water-operated electric boiler is stopped, it is required for a certain period of time to raise the heating water and the hot water to a predetermined temperature by the heating means during re-operation.

In the following description of the present invention, a detailed description of components that are widely known and used in the art to which the present invention belongs or does not belong will be omitted, and redundant description thereof will be omitted, To communicate more clearly.

1 and 2, the hybrid electric heater for heating hot water using solar heat of the present invention includes a solar heat exchanger 100, a cylinder 110, a heating unit 120 installed on the cylinder 110, A circulation pipe 130 and a water guide plate 140 installed in the heating means 120. The circulation pipe 120 is installed in the cylinder 110 and induces heat exchange with hot water by heated water in the cylinder 110. [ A direct water supply pipe 160 for supplying direct water to the heat exchange pipe 102 and the heat exchange pipe 150 side and a direct water supply pipe 160 connected between the heat exchange pipe 102 and the cylinder, A first pump 161 installed in a direct water supply pipe 160 connected to the heat exchange pipe 102 and a second pump 161 communicating with the cylinder 110 to supply / A heating water supply pipe 180 and a return pipe 200.

The solar heat exchanger 100 includes a heat collecting plate 101 having a supply line 103 and a collecting line 104 and extending to a predetermined length and a heat exchange pipe (102) are formed.

The heat exchange tube 102 has a structure that communicates with the supply line 103 and the recovery line 104 and is circulated.

The tubular body 110 is filled with a certain amount of water, and the heating means 120 and the heat exchange pipe 150 are separately installed inside the tubular body 110 at regular intervals.

Although not shown in the drawing, the cylinder may be provided with a temperature sensor, a flow rate gauge, an air vent, or the like.

The heating means 120 includes a heating tube 121 installed in series in the tubular body 110, a connection tube 122 for guiding water to circulate along the heating tube 121, And a heater 123 installed on both sides of the tube 121 and arranged to face each other.

The upper heating pipe 121 is formed with an inlet 125 through which water flows into the cylinder 110 and an outlet 126 is formed through the lower heating pipe 121 to communicate with the circulation pipe 130.

The heater 123 is installed on both sides of the heating pipe 121 to maximize heating of the water passing through the heating pipe 121.

A screw-type water guide plate 140 is installed on the outer surface of the heater 123 to guide water (heated water) to be moved in a spiral direction. Thus, water can be spirally rotated along the water guide plate 140 to maximize water contact with the outer surface of the heater 123.

The water guide plate 140 fixes the outer surface of the heater 123 to prevent the heater 123 from flowing due to friction or vibration generated when the heater 123 contacts the water The reliability of the product can be ensured.

The circulation pipe 130 guides the water heated by the heater 123 to circulate into the upper tubular body 110. The circulation pipe 130 is provided with a pump 112 for forcing water in the heating pipe 121 into the cylinder 110.

In this way, water in the tubular body 110 is forcibly circulated so that the water in the tubular body 110 can be compensated for the short time internal temperature.

When the water is supplied from outside, the temperature of the heated water passing through the heat exchanging pipe 150 due to the temperature of the hot water in the tub 110 is increased and used as hot water.

A plurality of support plates 131 are installed at a predetermined interval in the heat exchange pipe 150. The support plate 131 fixes the heat exchange pipe 150 and is made of a material having a high thermal conductivity of water, 150 can be improved.

The direct water supply pipe 160 supplies direct water to the heat exchange pipe 102 and the heat exchange pipe 150 side, one to the supply line 103 of the solar heat exchanger 100 and the other to the heat exchange pipe 150 side.

The first pump 161 is installed in a direct water supply pipe 160 connected to the supply line 103 of the solar heat exchanger 100 and forcibly directs the direct water along the heat exchange pipe 102.

A heating vertical water pipe 190 is installed between the heating water supply pipe 170 and the heat exchange pipe 150.

The heating vertical water pipe 190 directly supplies the heating water to the heat exchange pipe 150 when the use of the hot water suddenly increases, thereby inducing smooth use of the hot water.

A hot water storage tank (210) is installed between the heat exchange pipe (150) and the heating water return pipe (200).

A valve for supplying / blocking water and heating water is provided between the direct water supply pipe 160, the heating water supply pipe 170, the heat exchange pipe 150, the hot water storage tank 210 and the heating water return pipe 200 Respectively.

A third pump 181 and a fourth pump 211 are installed between the heating water supply pipe 180 and the hot water storage tank 210 and the heating water return pipe 200.

As described above, in the hybrid electric heater for heating hot water using solar heat of the present invention, water is first supplied through the direct-supply pipe 160, and the water is supplied to the heat- Are collected in the recovery line 104 via the heat exchange tube 102 connected to the supply line 103 and then introduced into the cylinder via the heating water supply pipe 170 connected to the recovery line 104. In this way, a certain amount of water flows into the cylinder and the valve of the direct supply pipe 160 supplied to the solar heat exchanger 100 is blocked when the set temperature is reached. When the valve of the direct-supply pipe 160 for supplying water to the heat-exchanging pipe 150 is opened, direct water is circulated along the heat-exchanging pipe 150 and is heat-exchanged at a predetermined temperature. At this time, When the hot water is not used, the valve connected to the heat exchange pipe 150 is closed to store the hot water into the hot water storage tank 210.

In the case where the amount of hot water is suddenly increased, the direct water supplied to the heat exchange pipe 150 is blocked, and hot water is supplied to the heat exchange pipe 150 along the heated vertical water pipe 190, .

During the daytime, the heating water is supplied by the solar heat exchanger 100 to maintain the temperature of the water in the cylinder. In the nighttime, however, when power is applied to the heating means 120 and the pump 112, The water in the tubular body 110 is circulated through the circulation tube 130 into the tubular body 110. At this time, the water passing through the heating tube 121 is first heated by the one side heater 123, The temperature of the water in a short time can be compensated by heating the water while circulating in a zigzag manner in a manner of being secondarily heated by the heater 123 on the opposite side. In other words, the water is heated by the heaters 123 installed on both sides while passing through the narrow space of the heating tube 121, so that the temperature of the water in the tubular body 110 can be raised to a predetermined temperature for a short time.

When the temperature of the water in the cylinder 110 falls below a preset temperature due to the use of heating water and hot water at night, the temperature of the water in the cylinder 110 is set by driving the heater 123 and the second pump 131 Temperature.

Then, the heated water passing through the heat exchange pipe 150 is directly supplied to the hot water or stored in the hot water storage tank 210. When the temperature of the hot water in the hot water storage tank 210 falls below a predetermined temperature, the hot water is returned to the tubular body 110 along the heating water return pipe 200.

As described above, according to the present invention, the heating water and the hot water are used by the solar heat exchanger 100 during the daytime, and the heating water temperature is compensated within a short time by the operation of the heating means 120 and the second pump 131 at night It can reduce the overall energy wastage.
