Referring to the functional relationship of the hot water heating apparatus for hot water mat according to the present invention configured as described above are as follows.

As shown in FIG. 1, after the hot water heating device 1 according to the present invention is connected to the hot water mat 30 using the connection hose 31, the water inlet cover 4 of the hot water heating device 1 is installed. Open the hot water storage tank 13, the appropriate amount of water and then adjust the dial of the temperature controller 6 to set the heating temperature, that is, the temperature of the hot water circulated.

At this time, the water level detection sensor 14 installed in the hot water storage tank 13 is maintained in the contact connection state because water is sufficiently introduced into the hot water storage tank 13, the conduction is installed on the bottom surface of the main body (2) The sensing switch 10 is maintained in the contact connection state because the hot water heating device 1 is normally placed without being tilted or fallen.

In this state, when the power switch 5 is turned on, the AC 220V power is supplied to the coil of the relay 9 through the power switch 5, the water level sensor 14, and the conduction detection switch 10, thereby maintaining the principle of the electromagnet. By connecting to the contact a of the relay 9 by the driving power is supplied to the electric heater 23 and the submersible electric motor pump 16.

When the underwater electric motor pump 16 is operated by the supplied driving power, water stored in the hot water storage tank 13 starts to flow into the hot water heating tank 15 by the underwater electric motor pump 16. do.

The water flowing into the hot water heating tank 15 by the submersible electric motor pump 16 gradually fills the internal space of the hot water heating tank 15, and the filled water is inside the hot water heating tank 15. The rod-shaped electric heater 23 is heated until the temperature set by the temperature controller 6 is reached.

As described above, the hot water heating device according to the present invention is not a method of heating the whole water stored in the hot water storage tank 13 like the conventional hot water heating device, but the submersible electric motor pump 16 from the hot water storage tank 13. By heating only the water of the hot water heating tank capacity introduced into the hot water heating tank 15 by the electric heater 23, the hot water heating efficiency is greatly improved.

When the inside of the hot water heating tank 15 is completely filled by the water flowing from the hot water storage tank 13, the air originally contained in the hot water heating tank 15 is as shown in FIG. It is discharged to the outside through the air discharge unit 19 installed on the upper portion of the hot water heating tank (15).

At this time, the air discharge portion 19 is a projection to form an air discharge groove 20b in the circumferential direction at the outer circumference of the upper surface of the air discharge hole 20 formed through the upper portion of the hot water heating tank 15 20a is formed and the upper surface of the protrusion 20a is provided with a cylindrical buoy 21 having a proper buoyancy, and the outside thereof is configured to cover the outside with a cap 22 through-hole 22a formed therethrough. When the water is gradually filled in the inside of the hot water heating tank 15, the air originally in the hot water heating tank 15 is discharged through the air discharge groove 20 formed between the mouth 21 and the protrusion 20a. It is discharged to the outside of the hot water heating tank 15 through the through hole 22a formed in the upper surface of the cap 22 through a gap formed between the inner surface of the cap 22 and the outer surface of the buoy 21.

When the air is completely discharged and the inside of the hot water heating tank 15 is completely filled with water, the water overflowing through the air discharge hole 20 raises the mouth 21 to close the through hole 22a of the cap 22. Since the water inside the hot water heating tank 15 is not discharged to the air discharge unit 19 at all.

The hot water heated by the electric heater 23 in a state in which the hot water heating tank 15 is filled to fill the inside of the hot water heating tank 15 is discharged from the hot water through the discharge end portion 15a by the pressure generated by the electric motor pump 16. It is discharged to (13a), the discharged hot water reaches almost 80 degrees, the discharged hot water is supplied to the inside of the hot water mat 30 through the connecting hose 31 to heat the hot water mat 30 and then connected again The hose 31 is returned to the hot water storage tank 13 through the hot water returning port 13b of the hot water heater 1.

At this time, the hot water returned to the hot water returning port (13b) reaches 50 to 60 degrees, this hot water is not directly introduced into the hot water storage tank 13, as shown in FIG. The hot water is first introduced into the inside of the hot water return vertical pipe portion 13c installed to correspond to the hot water return port 13b on the inner surface of the hot water storage tank 13, and then vertically heated to the top and bottom of the hot water storage tank 13. After filling the inside of the returning vertical pipe part 13c completely, it is mixed with the water stored in the inside of the hot water storage tank 13 as it flows down from the upper end of the hot water returning vertical pipe part 13c.

As described above, the hot water return vertical pipe part 13c separates the water surface of the hot water stored in the hot water storage tank 13 and the hot water introduced through the hot water return port 13b through the hot water return port 13b. By preventing the returned hot water from directly hitting the water stored in the hot water storage tank 13, it is possible not only to quickly discharge the air present in the hot water pipe of the hot water mat 30 during initial startup or when used for a long time. In order to reduce the load on the underwater electric motor pump 16 to circulate the hot water, the service life is extended, while the returned hot water passes through the vertical pipe portion 13c for hot water return, and the water temperature is gradually lowered. Since it is mixed in the hot water stored in the tank 13, it is possible to maintain the water temperature of the hot water stored in the hot water storage tank 13 to be lower than the water temperature of the hot water in the hot water heating tank 15. During use, the heat generated from the underwater electric motor pump 16 is cooled by the water stored in the hot water storage tank 13, which maintains the water temperature relatively lower than the water temperature inside the hot water heating tank, thereby preventing overheating of the underwater electric motor pump. The durability can be greatly improved.

When the heating and circulation process of the hot water as described above is continuously repeated and reaches the heating temperature set by the temperature controller 6, the temperature sensor 24 installed in the hot water heating tank 15 is located in the hot water heating tank 15. As the water temperature is detected and the contact point in the temperature sensor 24 is cut off, the power supplied to the electric heater 23 is cut off and the operation of the electric heater 23 is stopped so that the water temperature no longer rises. After this time, when the water temperature in the temperature heating tank 15 falls below the heating temperature, the contact point of the temperature sensor 24 connected to the temperature controller 6 is reconnected and power supply to the electric heater 23 is resumed. The hot water in the hot water heating tank 15 starts to be heated, and this process is repeated to maintain a constant heating temperature.

When the hot water introduced into the hot water storage tank 13 reaches a low water level by natural evaporation in the course of the normal operation as described above, the contact point is changed to the off state, or the user's water level sensor 14 is turned off. When the hot water heating device 1 is inclined or inverted due to carelessness, the contact of the conduction detection switch 10 is turned off.

As described above, when the contact point is changed to the off state of the water level sensor 14 or the conduction detection switch 10, the supply of driving power to the relay 9 is cut off and the operation of the relay 9 is stopped. The switch of 9) is connected to the b contact to turn on the water shortage warning light (7) to inform the user of danger.

In addition, if the bimetal 25 is supplied with power to the electric heater 23 in a state in which water is insufficient in the temperature heating tank 15 and the electric heater 23 is overheated, the contact is turned off by the heat. Since the power supplied to the electric heater 23 is cut off, an accident such as a fire due to overheating of the electric heater 23 can be prevented.

As described above, the hot water heating device for hot water mat according to the present invention has a low level in the hot water storage tank 13, or when the hot water heating device 1 is inclined or inverted due to careless handling of the user or the electric heater 23. When the overheat is cut off the power supplied to the electric heater 23 can be used more safely.

Hot water heating apparatus for hot water mat according to the present invention as described above is inserted into the hot water heating tank with a rod-shaped electric heater is installed inside the hot water storage tank installed in the main body consisting of the upper and lower cases, and the The external electric motor is configured to be connected to the submersible electric motor pump, so that only a certain amount of water introduced into the hot water heating tank by the submersible electric motor pump from the hot water storage tank without heating the entire water stored in the hot water storage tank is installed. Since it is heated by the hot water heating efficiency can be significantly improved.

In addition, the hot water heating device for hot water mat according to the present invention can be installed in the water stored inside the hot water storage tank for circulating the hot water electric motor pump not only can significantly reduce the motor noise generated during use, When used, the heat generated from the motor is cooled by the water stored in the hot water storage tank, which maintains the water temperature relatively lower than the water temperature inside the hot water heating tank, thereby preventing overheating of the motor, thereby greatly improving the durability of the underwater electric motor pump. It is effective.
