Please refer to the first figure. The integrated hot water supply system 1G provided by the preferred embodiment includes a water tank 2G, a solar heating module 3〇, a heat pump heating module 4〇, and a fuel heating. The module 5A, an electric heater 60, a control unit 70, and a human interface device 8A. The water tank 20 is used for storing water, and can be supplied with water to each of the heating modules 30, 40, 50 for heating, and then the water tank 2 is provided with the electric heater 60' directly in the water tank 20. The water is heated. Further, the water tank 20 is further provided with a first temperature sensor 22 for sensing the temperature of the water in the water tank 20. The solar heating module 30 has a solar heater 32, a solar heating circuit 34' connected between the water tank 20 and the solar heater 32, and a second temperature sensor 36. The solar heater 32 is adapted to absorb solar radiant heat to heat the water flowing therethrough. Therefore, the cold water in the water tank 20 which is located at a lower temperature of the lower layer can be flown into the solar heater 32 by the water inlet pipe 342 of the heating 5 M392938 circuit 34, and then returned to the water outlet pipe 344 of the heating circuit 34. The sink is 2 〇. The second temperature sensor 36 is mounted adjacent to the solar heater 32 for sensing the atmospheric temperature at the location. The heat pump heating module 40 has a heat pump heater 42, a heat pump heating circuit 44 connected between the water tank 20 and the heat pump heater 42, and a third temperature sensor 46. The heat pump heater 42 is configured to collect _ atmospheric heat energy to heat the water flowing therethrough. Therefore, the cold water in the water and the tank 20 which is located at a lower temperature of the lower layer can be flown into the hot pump heater 42 from the lu water inlet pipe 442 of the heating circuit 44, and then heated by the water outlet line 444 of the heating circuit 44. Return to the sink 20. The third temperature sensor 46 is configured to sense the temperature of the water flowing out of the heat pump heater 42 from the water outlet conduit 444. The fuel heating module 50 has a fuel heater 52, a fuel heating circuit 54 connected between the water tank 20 and the fuel heater 52, and a fourth temperature sensor 56. The fuel heater 52 generates heat by burning gas or other fuel to heat the water flowing therethrough. Therefore, the cold water in the water tank 20 at a lower temperature of the lower layer can be flown into the fuel heater 52 from the water inlet pipe 542 of the heating circuit 54, and then heated to flow back to the water tank 544 from the water outlet pipe 544 of the heating circuit 54. 20. The fourth temperature sensor residual unit 56 is configured to sense the temperature of the water flowing out of the fuel heater 52 from the water outlet conduit 544. In the components of the hot water supply system, the electric heater 60, the solar heater 32, the hot fruit heater 42, and the fuel heater 6 M392938 52 are all known in the art. I will not repeat them here. The control unit 70 is a programmable logic controller (PLC), and the solar heating module 30, the heat pump heating module 40, the fuel heating module 5, the electric heater 60, and the first The temperature sensor 22 is electrically connected to receive temperature information output by the temperature sensors 22, 36, 46, 56, and operation information output by the heaters 32, 42, 52, 60, and Each of the heaters 32, 42, 52, 60 can be automatically turned on or off based on the received information by means of a pre-written program therein. The human interface device 80 is electrically connected to the control unit 7 and can be used to switch the control unit 7G into an automatic control mode or a manual control mode and can be manually used by the user at any time according to requirements. The units 32, 42, 52, 60 are turned "on" or "off". Furthermore, the human interface device can also record the user's manual control mode and store it in an additional control mode. - In addition, the human-machine interface device 8 has a display 82, and (4) information received by the control unit 70, including the water tank 20 _ water temperature, atmospheric 'degree of water, and the start of each of the heaters 32, 42, 52, 6G Shape; brother, and 6 Xuan and other heaters 32, 42, 52 water temperature. In addition, the indication L: can also display the virtual screen of each heating module, so that the operation is more integrated by the above-mentioned integrated hot water supply system provided by the present invention, and the user can use the demand according to his needs. The preset automatic control mode 7 is arranged, and the human interface device 80 is disposed at a convenient place for monitoring the hot water supply condition of the system by the display 82 at any time, and manually controlling if necessary. Mode to operate. For example, the program of the control unit 7 can be set as the solar heater 32, the heat pump heater 42, according to the energy-saving degree of the heating, 42, 52, 60, and the starting order of the heating control in the automatic control mode. The fuel heater 52 and the electric heater 6〇 enable the system to preferentially activate the solar heating module 30, and automatically change when the atmospheric temperature sensed by the second temperature sensor 36 is lower than a set value. The heat pump heating mold 40 is activated, when the atmospheric temperature is lower than another set value (for example, 5 ° C, at which time the heat pump generally cannot obtain a heat source from the outside), or the third temperature sensor 46 senses the heat pump heater. When the outlet water temperature of 42 is lower than a preset value or the heating range does not meet the demand (that is, the time required to heat up to the temperature set value needs to be longer), the fuel heating module 5 is automatically changed to start; and when the fourth When the temperature sensor 56 senses that the water temperature of the fuel heater 52 is lower than another preset value or the heating range does not meet the demand (that is, the time required to heat up to the temperature set value needs to be longer), the temperature is automatically changed. The electric heater 6 is activated. Thereby, under the precondition that sufficient hot water can be supplied, the system will adopt the most energy-saving heating method, and the user can monitor the entire switching process and the related temperature by the display 82. If the user urgently needs hot water and wants to heat up in a faster manner, the manual control mode can be used to activate the electric heater 6〇, or even the fuel heating module 5〇 can be activated at the same time to accelerate the rise of the water temperature. In this way, the integrated hot water supply system not only has the advantage of saving energy, but also ensures that sufficient heat M392938 water is quickly supplied when necessary. Finally, it must be explained again that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention. Alternatives or variations of other equivalent elements should also be the scope of the patent application of the present application. Covered.
