[0002] A heat pump water heater is a device that uses heat pump technology to heat water. The working principle of a heat pump water heater is to extract low-temperature heat energy from environmental heat sources (such as water and air) through components such as a compressor, evaporator, heat exchanger, insulated water tank and electronic automatic controller, and then convert it into high-temperature heat energy and release it into the circulating medium (such as water and air) as a high-temperature heat source output.

[0003] Existing heat pump water heaters typically use mains electricity to power the heat pump, which then heats the water for the user. During peak electricity consumption periods, electricity bills are high, significantly increasing operating costs for frequent water heater users. Furthermore, water heaters usually have a tank where heated water is stored and then discharged for use. However, with prolonged use, the water in the tank is repeatedly heated and boiled, leading to sediment buildup, affecting water quality, and consequently compromising user safety.

[0035] 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.

[0036] 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.

[0037] like Figure 1 As shown, this embodiment provides an energy storage water heater, including a water heater body 1, a heat pump 2, and an energy storage module 3. The heat pump 2 is used to provide hot water to the water heater body 1. The energy storage module 3 is disposed inside the heat pump 2, and is electrically connected to the heat pump 2 and an external power source. When the energy storage water heater is in a first state, the energy storage module 3 provides electrical energy to the heat pump 2 to enable the heat pump 2 to operate. When the energy storage water heater is in a second state, the external power source provides power to the energy storage module 3 to enable the energy storage module 3 to store energy.

[0038] In this embodiment, the energy storage module 3 is an energy storage battery, and the external power source is AC mains power. The energy storage module 3 is electrically connected to both the heat pump 2 and the external power source. That is, the energy storage module 3 can be charged by AC mains power to store electrical energy, and it can also discharge to power the heat pump 2. When the energy storage water heater is in the first state, which is during peak electricity consumption, the energy storage water heater uses the energy storage module to provide power to the heat pump 2. The heat pump 2 heats the water and then provides hot water to the water heater body 1 for the user, avoiding high electricity bills during peak hours. When the energy storage water heater is in the second state, which is during off-peak hours, the energy storage module 3 is charged by AC mains power. After the energy storage module 3 is charged, when the user needs to use the energy storage water heater, it provides power to the heat pump 2 through the energy storage module 3. The heat pump 2 heats the water and then provides hot water to the water heater body 1 for the user. In this way, the energy storage module 3 discharges during peak electricity consumption and stores electricity during off-peak hours, which can greatly reduce the user's operating costs. Heat pump 2 can also be powered directly from the mains electricity. In this way, heat pump 2 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, energy storage module 3 can discharge electricity externally for emergency lighting and other purposes, improving the applicability of the water heater system.

[0039] like Figure 1 and 2 As shown, the water heater body 1 includes a water tank 11, a heat exchanger 12, an inlet pipe section 13, and an outlet pipe section 14; the water tank 11 is connected to the heat pump 2, and the heat pump 2 is used to provide hot water to the water tank 11; the heat exchanger 12 is disposed inside the water tank 11; the inlet pipe section 13 is connected to the inlet of the heat exchanger 12; and the outlet pipe section 14 is connected to the outlet of the heat exchanger 12.

[0040] In this embodiment, since the heat exchanger 12 is installed inside the water tank 11, the inlet pipe section 13 is connected to the inlet of the heat exchanger 12, and the outlet pipe section 14 is connected to the outlet of the heat exchanger 12. When the user needs to use the water heater, the heat pump 2 provides hot water to the water tank 11. Tap water is input through the inlet pipe section 13 and enters the heat exchanger 12. The hot water in the water tank 11 transfers heat to the tap water in the heat exchanger 12, thereby raising the temperature of the tap water in the heat exchanger 12. The heated tap water is then drained through the outlet pipe section 14 for the user's use. By continuously inputting tap water into the heat exchanger 12 through the inlet pipe section 13 for heating, and then draining it through the outlet pipe section for the user's use, 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.

[0041] As one embodiment, an inlet valve 131 is provided on the inlet pipe section 13, and an outlet valve 141 is provided on the outlet pipe section 14. By controlling the inlet valve 131, tap water is supplied to the heat exchanger 12. The tap water is heated and then supplied to the user by controlling the outlet valve 141. The heat exchanger 12 is a coil heat exchanger 12, which has high heat transfer efficiency and a large heat exchange area, thus improving heat exchange efficiency.

[0042] like Figure 1 As shown, the heat pump 2 and the water tank 11 are connected by a circulating water outlet pipe section 21 and a circulating water return pipe section 22; the heat pump 2 supplies hot water to the water tank 11 through the circulating water outlet pipe section 21, and the water tank 11 returns the water in the water tank 11 to the heat pump 2 through the circulating water return pipe section 22.

[0043] In this embodiment, the heat pump 2 and the water tank 11 are connected by a circulating water outlet pipe section 21 and a circulating water return pipe section 22. When the water tank 11 needs to be replenished with hot water, the heat pump 2 delivers hot water to the water tank 11 through the circulating water outlet pipe section 21. The hot water in the water tank 11 then exchanges heat with the tap water in the heat exchanger 12 to raise the temperature of the tap water in the heat exchanger 12. After heat exchange, the water in the water tank 11 cools down and is then delivered to the heat pump 2 through the circulating water return pipe section 22. The hot water then heats the water and is then delivered to the water tank 11 through the circulating water outlet pipe section 21. In this way, the hot water in the water tank 11 is continuously supplied, ensuring that the water heater system continuously outputs hot water.

[0044] like Figure 1 As shown, the direction from the outlet of the circulating water outlet pipe section 21 to the inlet of the circulating water return pipe section 22 is the first direction, and the direction from the inlet of the heat exchanger 12 to the outlet of the heat exchanger 12 is the second direction; the first direction and the second direction are opposite.

[0045] In this embodiment, the direction from the outlet of the circulating water outlet pipe section 21 to the inlet of the circulating water return pipe section 22 is the first direction, and the direction from the inlet of the heat exchanger 12 to the outlet of the heat exchanger 12 is the second direction. Figure 1 In the middle, the top to the bottom of the water tank 11 is the first direction, and the bottom to the top of the water tank 11 is the second direction; the first direction and the second direction are opposite, that is, when the heat exchanger 12 is exchanging heat, the tap water in the heat exchanger 12 and the hot water in the water tank 11 form a convection, which can greatly improve the heat exchange efficiency of the heat exchanger 12.

[0046] like Figure 1 As shown, the water heater body 1 also includes a water supply pipe section 15; one end of the water supply pipe section 15 is connected to the water inlet pipe section 13, and the other end of the water supply pipe section 15 is connected to the circulating return water pipe section 22.

[0047] In this embodiment, one end of the water replenishment pipe section 15 is connected to the water inlet pipe section 13, and the other end of the water replenishment pipe section 15 is connected to the circulating return water pipe section 22. When the hot water in the water tank 11 is lost, or when the water in the water tank 11 is drained for cleaning, the water replenishment pipe section 15 can be connected to the water inlet pipe section 13 to replenish the heat pump 2. The heat pump 2 heats the water and then replenishes the water tank 11 through the circulating water outlet pipe section 21.

[0048] like Figure 1 As shown, a water supply valve 151 is provided on the water supply pipe section 15, and the water supply valve 151 is used to control whether the water supply pipe section 15 is connected.

[0049] In this embodiment, by setting a water supply valve 151 on the water supply pipe section 15, when water needs to be added to the water tank 11, the water supply valve 151 is opened, the water inlet pipe section 13 replenishes the tap water to the heat pump 2, and the heat pump 2 then delivers hot water to the water tank 11 through the circulating water outlet pipe section 21, thereby realizing the water supply to the water tank 11.

[0050] like Figure 1 As shown, the water heater body 1 also includes an instant heating module 16 and an instant heating pipe section 17; one end of the instant heating pipe section 17 is connected to the outlet of the heat exchanger 12, and the other end of the instant heating pipe section 17 is connected to the inlet of the instant heating module 16; the outlet pipe section 14 is connected to the outlet of the instant heating module 16.

[0051] In this embodiment, one end of the instant heating pipe section 17 is connected to the outlet of the heat exchanger 12, and the other end of the instant heating pipe section 17 is connected to the inlet of the instant heating module 16. The outlet pipe section 14 is connected to the outlet of the instant heating module 16. When the temperature of the tap water heated by the heat exchanger 12 in the water tank 11 does not meet the user's needs, the tap water in the heat exchanger 12 is input into the instant heating module 16 through the instant heating pipe section 17. The instant heating module 16 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.

[0052] As one embodiment, the instant heating module 16 is a thick film heater, which can quickly heat tap water to meet the user's water needs.

[0053] like Figure 1 As shown, the water heater body 1 also includes a mixing pipe section 18; one end of the mixing pipe section 18 is connected to the water inlet pipe section 13, and the other end of the mixing pipe section 18 is connected to the water inlet of the instant heating module 16.

[0054] In this embodiment, one end of the mixing pipe section 18 is connected to the inlet pipe section 13, and the other end of the mixing pipe section 18 is connected to the inlet of the instant heating module 16. That is to say, the inlet of the instant heating module 16 connects the heat exchanger 12 and the inlet pipe section 13. In this way, the hot tap water after heat exchange in the heat exchanger 12 is first mixed with the cold tap water input through the mixing pipe section 18, and then enters the instant heating module 16. The instant heating module 16 can continuously heat the mixed water. The instant heating module 16 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.

[0055] like Figure 1As shown, the water heater body 1 also includes an electric regulating valve 19; the electric regulating valve 19 is installed at the water inlet of the instant heating module 16, and the electric regulating valve 19 is connected to both the mixing pipe section 18 and the instant heating pipe section 17 to regulate the amount of water flowing into the instant heating module 16 through the mixing pipe section 18 and the instant heating pipe section 17.

[0056] In this embodiment, the electric regulating valve 19 is installed at the inlet of the instant heating module 16. The electric regulating valve 19 is connected to both the mixing pipe section 18 and the instant heating pipe section 17. The electric regulating valve 19 controls the mixing of the hot tap water after heat exchange in the heat exchanger 12 and the cold tap water input through the mixing pipe section 18, and then the mixture enters the instant heating module 16 for heating. The instant heating module 16 works continuously, and the water heater system can continuously output hot water for users, thus improving the endurance of the water heater system.

[0057] like Figure 1 As shown, the water tank 11 is equipped with an air vent valve 111 and a drain valve 112; the air vent valve 111 is located at the upper part of the water tank 11, and the drain valve 112 is located at the lower part of the water tank 11.

[0058] In this embodiment, the vent valve 111 is located at the top of the water tank 11. Steam generated by the hot water in the water tank 11 can be discharged through the vent valve 111 at the top of the water tank 11, preventing excessive pressure inside the water tank 11. The drain valve 112 is located at the bottom of the water tank 11. When it is necessary to clean and drain the water tank 11, simply open the drain valve 112 at the bottom of the water tank 11 to drain the wastewater inside the water tank 11.

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.
