Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] like Figure 1 and 2As shown, this embodiment provides a water heater system, including a heating unit 1, a heat exchange unit 2, a water inlet unit 3, and a water outlet unit 4. The heating unit 1 includes a heat pump 11 and a water tank 12, the heat pump 11 and the water tank 12 are connected, and the heat pump 11 is used to provide hot water to the water tank 12. The heat exchange unit 2 includes a heat exchanger 21, which is disposed inside the water tank 12. The water inlet unit 3 includes an inlet pipe section 31, which is connected to the inlet of the heat exchanger 21. The water outlet unit 4 includes an outlet pipe section 41, which is connected to the outlet of the heat exchanger 21.

[0034] In this embodiment, the heat pump 11 is an air-source heat pump 11. The heat pump 11 heats water and supplies hot water to the water tank 12, which stores hot water. Since the heat exchanger 21 is located inside the water tank 12, the inlet pipe section 31 is connected to the inlet of the heat exchanger 21, and the outlet pipe section 41 is connected to the outlet of the heat exchanger 21. When the user needs to use the water heater, tap water is input through the inlet pipe section 31. The tap water enters the heat exchanger 21, and the hot water in the water tank 12 transfers heat to the tap water in the heat exchanger 21, thereby raising the temperature of the tap water in the heat exchanger 21. The heated tap water is then drained through the outlet pipe section 41 for the user's use. By continuously inputting tap water through the inlet pipe section 31 to the heat exchanger 21 for heating, and then draining it through the outlet pipe section, the repeated heating of tap water is avoided, ensuring that the hot water used by the user is fresh water, preventing the formation of scale and sediment, and ensuring the user's water safety.

[0035] As one embodiment, an inlet valve 32 is installed on the inlet pipe section 31, and an outlet valve 42 is installed on the outlet pipe section 41. By controlling the inlet valve 32, tap water is supplied to the heat exchanger 21. The tap water is heated and then supplied to the user by controlling the outlet valve 42. The heat exchanger 21 is a coil heat exchanger 21, which has high heat transfer efficiency and a large heat exchange area, thereby improving heat exchange efficiency.

[0036] like Figure 1 As shown, the heat pump 11 and the water tank 12 are connected by a circulating water outlet pipe section 13 and a circulating water return pipe section 14; the heat pump 11 supplies hot water to the water tank 12 through the circulating water outlet pipe section 13, and the water tank 12 returns the water in the water tank 12 to the heat pump 11 through the circulating water return pipe section 14.

[0037] In this embodiment, the heat pump 11 and the water tank 12 are connected by a circulating water outlet pipe section 13 and a circulating water return pipe section 14. When the water tank 12 needs to be replenished with hot water, the heat pump 11 delivers hot water to the water tank 12 through the circulating water outlet pipe section 13. The hot water in the water tank 12 then exchanges heat with the tap water in the heat exchanger 21 to raise the temperature of the tap water in the heat exchanger 21. After heat exchange, the water in the water tank 12 cools down and is then delivered to the heat pump 11 through the circulating water return pipe section 14. The hot water then heats the water again and is then delivered to the water tank 12 through the circulating water outlet pipe section 13. In this way, the hot water in the water tank 12 is continuously supplied, ensuring that the water heater system continuously outputs hot water.

[0038] like Figure 1 As shown, the direction from the outlet of the circulating water outlet section 13 to the inlet of the circulating water return section 14 is the first direction, and the direction from the inlet of the heat exchanger 21 to the outlet of the heat exchanger 21 is the second direction; the first direction and the second direction are opposite.

[0039] In this embodiment, the direction from the outlet of the circulating water outlet pipe section 13 to the inlet of the circulating water return pipe section 14 is the first direction, and the direction from the inlet of the heat exchanger 21 to the outlet of the heat exchanger 21 is the second direction. Figure 1 In the middle, the top to the bottom of the water tank 12 is the first direction, and the bottom to the top of the water tank 12 is the second direction; the first direction and the second direction are opposite, that is, when the heat exchanger 21 exchanges heat, the tap water in the heat exchanger 21 and the hot water in the water tank 12 form a convection, which can greatly improve the heat exchange efficiency of the heat exchanger 21.

[0040] like Figure 1 As shown, the heat pump 11 is equipped with an energy storage module 111, which is electrically connected to the heat pump 11 and to an external power source. When the water heater system is in a first state, the energy storage module 111 provides electrical energy to the heat pump 11 to enable the heat pump 11 to operate. When the water heater system is in a second state, the external power source provides power to the energy storage module 111 to enable the energy storage module 111 to store energy.

[0041] In this embodiment, the energy storage module 111 is an energy storage battery, and the external power source is AC mains power. The energy storage module 111 is electrically connected to the heat pump 11 and the external power source. That is, the energy storage module 111 can be charged by AC mains power to store electrical energy, and the energy storage module 111 can also discharge to power the heat pump 11. When the water heater system is in the first state, which is during peak electricity consumption, the water heater system uses the energy storage module to provide power to the heat pump 11. The heat pump 11 heats the water and provides hot water to the water tank 12, thereby exchanging heat with the tap water in the heat exchanger 21 for user use, avoiding high electricity prices during peak electricity consumption. When the water heater system is in the second state, which is during off-peak electricity consumption, the energy storage module 111 is charged by AC mains power. After the energy storage module 111 is charged, when the user needs to use the water heater system, the energy storage module 111 provides power to the heat pump 11. In this way, the user's electricity cost can be greatly reduced. The heat pump 11 can also be powered directly from the mains electricity. In this way, the heat pump uses electricity, air source heat pump, and battery energy storage to achieve energy saving, high efficiency, and meet the needs of large water usage. Of course, during power outages, the energy storage module 111 can discharge externally for emergency lighting and other purposes, improving the applicability of the water heater system.

[0042] like Figure 1 As shown, the water inlet unit 3 also includes a water replenishment pipe section 33; one end of the water replenishment pipe section 33 is connected to the water inlet pipe section 31, and the other end of the water replenishment pipe section 33 is connected to the circulating return water pipe section 14.

[0043] In this embodiment, one end of the water replenishment pipe section 33 is connected to the water inlet pipe section 31, and the other end of the water replenishment pipe section 33 is connected to the circulating return water pipe section 14. When the hot water in the water tank 12 is lost, or when the water in the water tank 12 is drained for cleaning, the water replenishment pipe section 33 can be connected to the water inlet pipe section 31 to replenish the heat pump 11. The heat pump 11 heats the water and then replenishes the water tank 12 through the circulating outlet water pipe section 13.

[0044] like Figure 1 As shown, a water supply valve 331 is provided on the water supply pipe section 33, and the water supply valve 331 is used to control whether the water supply pipe section 33 is connected.

[0045] In this embodiment, by setting a water supply valve 331 on the water supply pipe section 33, when water needs to be added to the water tank 12, the water supply valve 331 is opened, the water inlet pipe section 31 replenishes the tap water to the heat pump 11, and the heat pump 11 then delivers hot water to the water tank 12 through the circulating water outlet pipe section 13, thereby realizing the water supply to the water tank 12.

[0046] like Figure 1As shown, the water heater system also includes an instant heating unit 5, which includes an instant heating module 51 and an instant heating pipe section 52; one end of the instant heating pipe section 52 is connected to the outlet of the heat exchanger 21, and the other end of the instant heating pipe section 52 is connected to the inlet of the instant heating module 51; the outlet pipe section 41 is connected to the outlet of the instant heating module 51.

[0047] In this embodiment, one end of the instant heating pipe section 52 is connected to the outlet of the heat exchanger 21, and the other end of the instant heating pipe section 52 is connected to the inlet of the instant heating module 51. The outlet pipe section 41 is connected to the outlet of the instant heating module 51. When the temperature of the tap water heated by the heat exchanger 21 in the water tank 12 does not meet the user's needs, the tap water in the heat exchanger 21 is input into the instant heating module 51 through the instant heating pipe section 52. The instant heating module 51 further heats the tap water to reach the temperature required by the user, and then discharges it through the drain pipe section for the user's use, thus avoiding the situation where the hot water runs out and improving the endurance of the water heater system.

[0048] As one embodiment, the heating module 51 is a thick film heater, which can quickly heat tap water to meet the user's water needs.

[0049] like Figure 1 As shown, the instant heating unit 5 also includes a mixing pipe section 53; one end of the mixing pipe section 53 is connected to the water inlet pipe section 31, and the other end of the mixing pipe section 53 is connected to the water inlet of the instant heating module 51.

[0050] In this embodiment, one end of the mixing pipe section 53 is connected to the inlet pipe section 31, and the other end of the mixing pipe section 53 is connected to the inlet of the instant heating module 51. That is to say, the inlet of the instant heating module 51 is connected to the heat exchanger 21 and the inlet pipe section 31. In this way, the hot tap water after heat exchange in the heat exchanger 21 is first mixed with the cold tap water input through the mixing pipe section 53, and then enters the instant heating module 51. The instant heating module 51 can continuously heat the mixed water. The instant heating module 51 works continuously so that the water heater system can continuously output hot water for users, which greatly improves the endurance of the water heater system.

[0051] like Figure 1 As shown, the instant heating unit 5 also includes an electric regulating valve 54; the electric regulating valve 54 is installed at the water inlet of the instant heating module 51, and the electric regulating valve 54 is connected to both the mixing pipe section 53 and the instant heating pipe section 52 to regulate the amount of water flowing into the instant heating module 51 through the mixing pipe section 53 and the instant heating pipe section 52.

[0052] In this embodiment, the electric regulating valve 54 is installed at the inlet of the instant heating module 51. The electric regulating valve 54 is connected to both the mixing pipe section 53 and the instant heating pipe section 52. The electric regulating valve 54 controls the mixing of the hot tap water after heat exchange in the heat exchanger 21 and the cold tap water input through the mixing pipe section 53, and then the mixture enters the instant heating module 51 for heating. The instant heating module 51 works continuously, and the water heater system can continuously output hot water for users, thus improving the endurance of the water heater system.

[0053] like Figure 1 As shown, the water tank 12 is equipped with an air vent valve 121 and a drain valve 122; the air vent valve 121 is located at the upper part of the water tank 12, and the drain valve 122 is located at the lower part of the water tank 12.

[0054] In this embodiment, the vent valve 121 is located at the top of the water tank 12. Steam generated by the hot water in the water tank 12 can be discharged through the vent valve 121 at the top of the water tank 12, preventing excessive pressure inside the water tank 12. The drain valve 122 is located at the bottom of the water tank 12. When it is necessary to clean and drain the water tank 12, simply open the drain valve 122 at the bottom of the water tank 12 to drain the wastewater inside the water tank 12.

Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
