Referring to the operational relationship of the hot water boiler for hot water mat according to the present invention configured as described above are as follows.

The hot water boiler for hot water mat according to the present invention is used in a state connected to the hot water mat 20 using a pair of connecting hoses 21 and 22, as shown in FIG. When the hot water boiler 1 is connected to the hot water mat 20 by a pair of connection hoses 21 and 22, when the power switch of the hot water boiler 1 is turned on, the inside of the hot water boiler 1 is initially Since there is no water in the hot water heating tank 2, the high water level detecting portion 8a and the low water level detecting portion 8b of the first water level detecting sensor 8 installed in the inside of the hot water storage tank 10 The water level detection sensor 15 is all in the state of falling down, the water shortage warning light is turned on the hot water boiler (1).

In order to inject water into the hot water boiler 1 in this state, as shown in Figure 4a, the connection hose 22 is connected to the hot water supply end 14 of the hot water storage tank (10) The water is injected into the inside of the hot water mat 20 and the hot water boiler 1 through the ends of the separated connecting hoses 22. At this time, as a mechanism for injecting water into the connection hose 22, it is preferable to use a conventional manual water pump or to use a specially prepared water injection mechanism.

When water is injected through the connection hose 22 separated from the hot water supply end 14 of the hot water storage tank 10 as described above, the injected water fills the hot water hose installed inside the hot water mat 20. Next, while pushing up the check valve (5) provided in the hot water heating means (6) of the hot water heating tank (2) is filled into the hot water heating tank (2) by flowing into the interior of the hot water heating tank (2), At this time, both the low water level detecting unit 8b and the high water level detecting unit 8a of the first water level detecting sensor 8 installed inside the hot water heating tank 2 float to the ON state so that the electric heater 9 operates. do.

Subsequently, water is injected into the hot water heating tank 2 to a high water level state through the water refill 4 formed in the upper portion of the hot water heating tank 2 so that the low water level sensing portion of the first water level sensor 8 8b) and the high water level detecting part 8a are lifted up and turned on, so that the water shortage warning lamp is turned off, and then the stopper 3 is fastened to the upper portion of the hot water heating tank 2 to secure the water replenisher 4 firmly. After the sealing is completed by reconnecting the connection hose 22 separated from the hot water supply end 14 of the hot water storage tank 10, the water injection work for the hot water boiler 1 is completed.

When the water injected into the hot water heating tank 2 begins to be heated by the electric heater 9 after the water injection work for the hot water boiler 1 is completed as described above, the hot water heating tank 2 As the steam is generated, the pressure in the hot water heating tank 2 is increased by the generated steam, and as the pressure in the hot water heating tank 2 is increased, the steam is generated inside the hot water heating tank 2 by the steam pressure. Check valve is provided in the hot water inlet end 13 of the hot water storage tank 10 via the hot water discharge end 7 and the connection pipe 16 of the hot water heating tank 2 as shown in FIG. Opening (12) is pushed into the interior of the hot water storage tank (10). At this time, the air inside the hot water storage tank 10 is discharged to the outside through the air discharge end 11 formed in the upper portion of the hot water storage tank 10.

When the steam pressure is formed inside the hot water heating tank 2, the check valve 5 provided in the hot water recycling means 6 is operated by the steam pressure to block the flow path of the hot water recycling means 6. Hot water generated inside the heating tank 2 is not discharged to the hot water recycling means 6 at all.

As the hot water generated in the hot water heating tank 2 is moved into the hot water storage tank 10 by the steam pressure and stored therein, the water level of the hot water heating tank 2 is gradually lowered. When the water level of (2) is continuously lowered and the low water level detecting portion 8b of the first water level sensor 8 is turned off and turned OFF, the electric heater 9 is cut off, and thus the operation of the electric heater 9 is stopped. At this time, the second water level detection sensor 15 installed in the hot water storage tank 10 floats as the hot water is filled in the hot water storage tank 10 to be in an OFF state.

In this way, the low water level detecting portion 8b of the first water level sensor 9 is turned off and becomes OFF, or the second water level sensor 15 floats to be turned OFF so that the electric power of the electric heater 9 is cut off. When the operation of the heater 9 is stopped, the steam generated in the hot water heating tank 2 is recovered as water, and the pressure inside the hot water heating tank 2 drops sharply to form a vacuum state. Thus, the hot water heating tank ( If a vacuum state is formed inside 2), a strong suction force is generated by this vacuum state, so that the hot water inside the hot water mat 2 is heated in the hot water heating tank 2 as shown in FIG. 4C. It is sucked into the inside of the hot water heating tank (2) through (6).

At this time, when a vacuum state is formed in the hot water heating tank 2, the check valve 12 provided in the hot water inlet end 13 of the hot water storage tank 10 is operated by the vacuum suction input to operate the hot water inlet end. Since the flow path of (13) is blocked, the hot water stored in the hot water storage tank 2 does not escape to the hot water inlet end 13.

As the hot water in the hot water mat 20 is sucked into the hot water heating tank 2 by the vacuum suction input formed in the hot water heating tank 2, the inside of the hot water mat 20 is chained. In this case, a vacuum state is formed, and when a vacuum state is formed inside the hot water mat 20, a strong suction force is generated by the vacuum, and thus, the inside of the hot water storage tank 10 is stored as shown in FIG. 4D. The hot water was sucked into the inside of the hot water mat 20 through the hot water supply end 14 to circulate the hot water.

The water level of the hot water heating tank 2 as the hot water in the hot water mat 20 is sucked into the hot water heating tank 2 by the vacuum suction input formed in the hot water heating tank 2 as described above. Is raised again so that the low water level detection unit 8b and the high water level detection unit 8a of the first water level detection sensor 8 are turned on, and the hot water stored in the hot water storage tank 10 is heated in the hot water mat 20. When the water level of the hot water storage tank 10 is lowered as the second water level sensor 15 is turned on as the water is sucked into the inside of the heater, the electric heater 9 installed inside the hot water heating tank 2 is operated again. By doing so, the above hot water circulation process is repeated.

If the low water level detection unit 8b of the second water level detection sensor 15 of the hot water storage tank 10 and the first water level detection sensor 8 of the hot water heating tank 2 is in an ON state, the high water level detection unit 8a If the water level warning light is turned on when the water level is low, the high water level detecting part 8a of the first level sensor 8 of the hot water heating tank 2 is turned off and the hot water storage tank 10 is turned off. Coincides with the water shortage warning lamp lighting up when the second water level sensor 15 is turned ON. Accordingly, when the water shortage warning light is turned on, the stopper 3 coupled to the upper portion of the hot water heating tank 2 is opened to replenish water.

And, the hot water boiler according to the present invention is connected to the hot water recovered by using the hot water temperature sensor attached to the outside of the connection hose 21 connected to the hot water heating means 6 of the hot water heating tank (2) The temperature is controlled by measuring the surface temperature of 21). For example, when the temperature reaches about 35 degrees, the electric heater 9 is turned off to stop the operation of the hot water boiler 1, and when the temperature falls below that level. The electric heater 9 is started again.

As described above, the hot water boiler for hot water mat according to the present invention is a hot water storage tank in which hot water generated in the hot water heating tank 2 is moved and stored outside of the hot water heating tank 2 in which the electric heater 9 is embedded. 10 is connected to the hot water storage tank 10 by the steam pressure generated in the hot water heating tank 2 when the hot water is heated in the hot water heating tank 2 when the hot water is heated by the electric heater 9. The hot water in the hot water mat 20 is circulated by the vacuum suction input formed inside the hot water heating tank 2 after moving and storing the hot water without the electric motor pump for hot water circulation used in the conventional hot water mat boiler. The simple circulation makes it possible to significantly reduce noise and vibration, as well as significantly improve durability.

In addition, the hot water boiler for hot water mat according to the present invention, even if the hot water hose of the hot water mat 20 is folded due to user's carelessness and the circulation of hot water is blocked, the steam pressure generated in the hot water heating tank 2 is the hot water storage tank 10. ), It can be exhausted and prevent the risk of explosion, greatly improving safety.
