[0025] As described in the background section, heat pump water heaters use a small amount of electricity as a driving force and a refrigerant as a heat transfer medium to continuously absorb low-grade heat energy from the air and convert it into usable high-grade heat energy. This heat energy is then released into the water to be heated to produce domestic hot water, which is then delivered to the user through hot water pipes. However, in existing heat pump water tanks, during the water inlet process, cold water directly impacts the hot water area inside the tank, resulting in a large area of ​​mixed hot and cold water. This affects the continuous output of hot water from the tank, reducing user comfort and experience.

[0026] Based on this, please refer to Figure 1 This utility model provides a heat pump water tank 100, which effectively improves the aforementioned technical problems. Specifically, it reduces the turbidity zone between hot and cold water, increases the continuous hot water output from the tank, and thus enhances user comfort and experience. The heat pump water tank 100 will be described in detail below.

[0027] Figure 1 This is a structural schematic diagram of the heat pump water tank 100 provided in this embodiment, combined with... Figure 1The heat pump water tank 100 includes a tank body 10, a hot water outlet pipe 20, a cold water inlet pipe 30, and a spray head 40. The hot water outlet pipe 20 is located inside the tank body 10, and the cold water inlet pipe 30 is located inside the tank body 10 and is spaced apart from the hot water outlet pipe 20. The spray head 40 is connected to the cold water inlet pipe 30 and is located inside the tank body 10. The spray head 40 is provided with multiple spray holes 41.

[0028] Understandably, by setting up the spray head 40, cold water can be sprayed into the tank 10 from multiple spray holes 41. This reduces the pressure when cold water enters the tank 10, avoids cold water directly impacting the hot water area inside the tank 10, thereby reducing the mixed hot and cold water area, increasing the continuous hot water output of the water tank, and thus improving the user's comfort and experience.

[0029] Furthermore, the housing 10 has a top 11 and a bottom 12 arranged opposite to each other, with the top 11, hot water outlet pipe 20, cold water inlet pipe 30, and bottom 12 arranged in sequence at intervals. Among them, a plurality of spray holes 41 are arranged on the side of the spray head 40 near the bottom 12, and the spray head 40 is used to spray cold water toward the bottom 12 through the plurality of spray holes 41.

[0030] According to thermodynamic principles, hot water in the tank 10 is typically distributed in the upper layer, while cold water is typically distributed in the lower layer. The middle area can be understood as a mixed area of ​​hot and cold water. By setting multiple spray holes 41 on the side of the spray head 40 near the bottom 12, cold water is sprayed from the multiple spray holes 41 towards the bottom 12 of the tank 10, that is, towards the hot water area away from the upper layer. This further avoids cold water directly impacting the hot water area inside the tank 10, thereby further increasing the continuous hot water output of the tank and improving user comfort and experience.

[0031] It should be noted that, specifically in this embodiment, the hot water outlet pipe 20 is located near the top 11 of the tank 10, and the cold water inlet pipe 30 is located near the bottom 12 of the tank 10, which can further reduce the mixed water area of ​​hot and cold water and increase the continuous hot water output of the tank.

[0032] In order to further reduce the pressure when cold water enters the tank 10 and avoid cold water directly impacting the hot water area inside the tank 10, the number of spray heads 40 can be set to multiple. Multiple spray heads 40 are arranged at intervals along the extension direction of the cold water inlet pipe 30 and are all connected to the cold water inlet pipe 30.

[0033] Understandably, by setting multiple spray heads 40 along the extension direction of the cold water inlet pipe 30, cold water can be sprayed at different locations in the lower cold water area, thereby improving the uniformity of cold water mixing, reducing the intensity of subsequent turbid water mixing, and further improving the hot water output effect.

[0034] Specifically, the hot water outlet pipe 20 includes a horizontal section 21 and a vertical section 22 that are interconnected. Both the horizontal section 21 and the vertical section 22 are located inside the housing 10, and the horizontal section 21 is spaced apart from the cold water inlet pipe 30. The vertical section 22 is located on the side of the horizontal section 21 away from the cold water inlet pipe 30. Specifically, in this embodiment, the vertical section 22 extends toward the top 11 of the housing 10.

[0035] As explained above, hot water is typically concentrated in the upper area of ​​the tank 10, and the closer to the top 11 of the tank 10, the higher the outlet water temperature. Therefore, by extending the vertical section 22 towards the top 11 of the tank 10, that is, by positioning the end of the vertical section 22 away from the horizontal section 21 in the top 11 area of ​​the tank 10, the hot water with higher temperatures inside the tank 10 can be discharged, further improving the continuous hot water output and enhancing user comfort and experience.

[0036] It should be noted that in this embodiment, there is one hot water outlet pipe 20; of course, in some other embodiments, in order to facilitate the simultaneous delivery of hot water to multiple users, the number of hot water outlet pipes 20 can also be set to multiple, and multiple hot water outlet pipes 20 can be arranged at intervals around the circumference of the tank 10.

[0037] Please continue to combine Figure 1 In order to monitor the water temperature inside the tank 10 and facilitate temperature adjustment, in this embodiment, the heat pump water tank 100 also includes a first temperature sensor 51, which is disposed in the tank 10 and located between the hot water outlet pipe 20 and the cold water inlet pipe 30.

[0038] As is easy to understand, the first temperature sensor 51 can obtain the water temperature inside the tank 10 in real time. If the temperature is lower than the set value, the heat pump system will run to heat the hot water, thereby adjusting the water temperature of the tank 10 to a suitable state.

[0039] Furthermore, in order to improve the accuracy of water temperature measurement, the heat pump water tank 100 also includes a second temperature probe 52. The second temperature probe 52 is disposed in the tank body 10, and is spaced apart from the hot water outlet pipe 20, and is located on the side of the hot water outlet pipe 20 away from the first temperature probe 51.

[0040] In other words, the first temperature probe 51 and the second temperature probe 52 can measure the water temperature at different locations inside the tank 10, namely the water temperature in the upper and lower areas, and compare the water temperatures at the two locations to reasonably control the degree of hot water heating and the amount of cold water entering, thereby more accurately regulating the water temperature inside the tank 10 and ensuring the user's comfort and experience.

[0041] In this embodiment, the heat pump water tank 100 also includes a water outlet connector 61, which is located outside the tank body 10; one end of the hot water outlet pipe 20 extends from inside the tank body 10 and is connected to the water outlet connector 61. By providing the water outlet connector 61, it is convenient to connect other water pipes to the hot water outlet pipe 20.

[0042] Similarly, in order to facilitate the connection between the external water pipe and the cold water inlet pipe 30, in this embodiment, the heat pump water tank 100 also includes a water inlet connector 62, which is located outside the tank body 10; one end of the cold water inlet pipe 30 extends out from inside the tank body 10 and is connected to the water inlet connector 62.

[0043] In addition, in this embodiment, in order to facilitate the discharge of sewage from the tank 10, the heat pump water tank 100 also includes a drain pipe 71, which is connected to the bottom 12 of the tank 10.

[0044] Similarly, to facilitate the connection of other pipes to the drain pipe 71, in this embodiment, the heat pump water tank 100 also includes a drain connector 72, which is connected to the end of the drain pipe 71 away from the tank body 10.

[0045] In summary, the embodiments of this utility model provide a heat pump water tank 100, which includes a tank body 10, a hot water outlet pipe 20, a cold water inlet pipe 30, and a spray head 40. The hot water outlet pipe 20 is disposed inside the tank body 10, and the cold water inlet pipe 30 is disposed inside the tank body 10 and spaced apart from the hot water outlet pipe 20. The spray head 40 is connected to the cold water inlet pipe 30 and is located inside the tank body 10, and the spray head 40 has multiple spray holes 41. By setting the spray head 40, cold water can be sprayed into the tank body 10 from multiple spray holes 41, which can reduce the pressure when cold water enters the tank body 10, avoid cold water directly impacting the hot water area inside the tank body 10, thereby reducing the mixed water area of ​​hot and cold water, increasing the continuous hot water output of the water tank, and thus improving the user's comfort and experience.

[0046] The above description is merely a specific embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
