The check valve 51 and the flow of water replenishment will be described in more detail with reference to FIG. 4.

First, the heating water flowing in the generation is a phenomenon that the heating water is insufficient due to evaporation, etc., for this purpose, a pipe for supplementing the additional heating water is required. That is, in this case, the present invention solves this through the water supplement pipe 50, and controls the flow of water by the check valve (51).

More specifically, when the heating water in the household is insufficient, the pressure of the heating pipe (piping through which the heating water flows in the household flows) is reduced, and due to the pressure difference, the check valve 51 is opened to flow in from the hot water supply pipe 40. Since the hot water is directly introduced into the heating water supply pipe 20 through the water supplement pipe 50, the insufficient water in the heating pipe is filled. When the water in the heating pipe is filled, the pressures of both sides of the check valve 51 are equal. As it clears, the check valve closes to stop the water replenishment.

As a result, the present invention can solve the problem of the lack of the heating water flowing in the heating pipe by automatically supplying hot water automatically when the check valve 51 is insufficient in the heating pipe.

Furthermore, the third pipe 43 is further provided with a solenoid valve 45 to control the hot water supply of the hot water supply pipe 40 to control the heating.

First, the function of the three-way valve 17 will be described. As shown in FIG. 4, the three-way valve 17 is operated by the first-three pipes 13 and the first-four pipes 14. It is made to communicate, or to communicate the high-pressure injection pipe 70 and the 1-4 pipe (14).

Therefore, normally, as shown in FIG. 4A, the 1-3 pipe 13 and the 1-4 pipe 14 communicate with each other, and supply the returned heating water to the heat exchanger 60, and exchange heat. When the inside of the machine needs to be cleaned, or when hot water is rapidly supplied to the heating pipe during the first construction, as shown in FIG. 4B, the three-way valve 17 is operated manually so that the high-pressure jet pipe 70 By connecting the first to fourth pipes 14, the hot water introduced into the hot water supply pipe 40 through the first to four pipes 14 is introduced into the heat exchanger 60, that is, the portion where the original heating water is returned. Clean the secondary pipe by passing it through the secondary pipe inside the heat exchanger.

That is, the hot water introduced through the hot water supply pipe 40 is hot water supplied from a machine room, etc., and its water pressure is obviously higher than that of the heating water, and the hot water of the strong water pressure is directly injected into the secondary pipe of the heat exchanger 60. As a result, it is possible to remove foreign substances in the secondary pipe.

In addition, for this purpose, the heating pipe, more precisely, a portion connected to the heating water supply pipe 20 is further provided with a drain valve (DV), when the three-way valve 17 to operate when cleaning the heat exchanger (60) It is desirable to allow foreign substances to be discharged.

Furthermore, as mentioned above, the three-way valve 17 can be operated even when the initial construction to fill the heating water more quickly, this should not be limited interpretation of the scope.

In addition, the water hammer (W) is the solenoid valve is blocked by a signal when the room temperature is above the set temperature, at this time, the water hammer phenomenon occurs due to the rapid fluid blocking, if the heat exchanger 60 is damaged Wearing clothes,

When the check valve is opened due to instantaneous overpressure and the heating water is excessively filled, the pressure of the heating water increases so as to prevent the problem of pipe rupture in the household.

Even if the solenoid valve and the check valve are suddenly blocked or opened, the supplied hot water is introduced into the water hammer preventer (W) to prevent a water hammer phenomenon from occurring.

In addition, the bent shape and structure of the various pipes as described above are made to miniaturize the pipe module (M) according to the present invention, and also for miniaturization and installation convenience by arranging the end of each pipe side by side for convenience of installation. All have features that can be met.

In addition, the housing (H), it is preferable that the leak detection sensor (not shown) is further provided on the inner bottom of the housing (H) more accurately.

The leak detection sensor detects a leak in various pipes, heat exchangers, connection parts, etc. provided in the housing (H) to stop the operation of the pump and to close the solenoid valve to stop the heat exchanger operation. do.

Furthermore, the housing further includes an alarm member interlocked with the leak detection sensor, and when the leak detection sensor operates, the alarm member emits an alarm so that the user can recognize the leak and check and repair the leak.
