Description

Technical Field

[0001] This utility model relates to the field of heat pump water tank technology, and in particular to an energy-saving heat pump water tank that prevents repeated heating. Background Technology

[0002] A heat pump water tank is a water storage device that is paired with a heat pump system. Its core function is to store hot water and maintain a stable temperature. It is equipped with heat exchange coils that connect to the heat pump unit to achieve heat exchange. The water tank is mostly made of stainless steel or enamel, which is corrosion-resistant and durable. It comes in various sizes according to capacity and is suitable for homes, hotels and other scenarios. It can provide constant temperature hot water as needed. When paired with a heat pump unit, it can efficiently utilize energy and is more energy-efficient than traditional water tanks. It is an important component of an air source heat pump system.

[0003] Heating tubes are typically installed inside heat pump water tanks. There are generally two types of heating tubes: immersion condensers and external coil condensers. Immersion condensers are spirally coiled inside the water tank and are in direct contact with the water. However, current immersion condensers are usually fixed inside the water tank by a connecting bracket, which is bolted to the inner wall of the water tank to ensure stable operation. However, this installation method requires drilling holes in the inner wall of the water tank to install the connecting bracket. Direct drilling can damage the inner wall of the water tank, reduce the heat preservation effect, and increase the risk of leakage. In view of this, we propose an energy-saving heat pump water tank that prevents repeated heating. Utility Model Content

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution: an energy-saving heat pump water tank to prevent repeated heating, including a water tank 1. A top cover 2 is provided on the upper surface of the water tank 1. A vertical rod 3 is fixedly connected to the lower surface of the top cover 2. A connecting rod 4 is fixedly connected to the outer surface of the vertical rod 3. An annular mounting plate 5 is fixedly connected to the end of the connecting rod 4. An L-shaped clearance rod 6 is fixedly connected to the lower surface of the annular mounting plate 5. An arc-shaped fixing plate 7 is fixedly connected to the end of the horizontal bar of the L-shaped clearance rod 6. A heating tube 8 is welded to the surface of the arc-shaped fixing plate 7. Two connecting tubes are provided on the lower surface of the top cover 2. The heating tube 8 is connected to two interfaces 9 at both ends. Two clearance grooves 10 are opened on the upper surface of the top cover 2. The bottom wall of the two clearance grooves 10 is provided with water inlet 11 and water outlet 12. The top cover 2 is provided with connecting components. By using the arc-shaped fixing plate 7 and vertical rod 3, it is possible to fix the heating tube 8 without drilling holes in the inner wall of the water tank 1, thereby reducing damage to the water tank 1 and avoiding insufficient local heat preservation performance. At the same time, by utilizing the long arc-shaped fixing plate 7, the heating tube 8 can be fixed as a whole, and the stability is guaranteed.

[0019] Furthermore, the connecting assembly includes a first flange ring 13, which is fitted onto the outer surface of the top cover 2. A second flange ring 14 is fitted onto the outer surface of the water tank 1. Both the first flange ring 13 and the second flange ring 14 have through holes 15. A fixing bolt 16 is provided between the first flange ring 13 and the second flange ring 14, and the first flange ring 13 and the second flange ring 14 are connected by the fixing bolt 16. An embedded sealing groove 17 and a conical groove 18 are provided on the upper surface of the water tank 1. A sealing ring 19 is fixedly connected to the lower surface of the top cover 2. A conical ring 20 that matches the conical groove 18 is fixedly connected to the lower surface of the top cover 2. An extension rod 21 is fixedly connected to the lower surface of the vertical rod 3. The lower end of the extension rod 21... A temperature sensor 22 is installed, and a stabilizing ring 23 is fitted on the outer surface of the extension rod 21. A stabilizing rod 24 is fixedly connected between the stabilizing ring 23 and the arc-shaped fixing plate 7. A lifting ring 25 is fixedly connected to the surface of the top cover 2. Both the water tank 1 and the top cover 2 are composed of an inner liner 26, a foam layer 27, an aluminum foil layer 28, and an outer layer 29. The aluminum foil layer 28 is located inside the outer layer 29, the foam layer 27 is located inside the aluminum foil layer 28, and the inner liner 26 is located inside the foam layer 27. This design not only allows the temperature sensor 22 located at the bottom axis to accurately detect the temperature and avoid temperature errors caused by the sensor being close to the heating tube 8, but also reduces internal heat loss and heating intervals by using the foam layer 27 and the aluminum foil layer 28, thereby achieving energy saving.

[0020] Among them, foam layer 27 is high-density polyurethane foam (density ≥ 40 kg / m³). 3 With a thermal conductivity of <0.03W / (m・K), it can provide excellent heat preservation, while the aluminum foil layer 28 can further reduce heat loss by radiation and increase the difference between the start-up temperature and the stop temperature, thus further avoiding frequent heating.

[0021] Working principle: When connecting the heating tube 8, it can be directly welded to the arc-shaped fixing plate 7 externally, and the two ends of the heating tube 8 are connected to the two connection ports 9. Then, the top cover 2 is lifted by the cooperation of the rope and the lifting ring 25, and the heating tube 8 enters the interior of the water tank 1. When the first flange ring 13 and the second flange ring 14 are connected and combined, the sealing ring 19 will enter the interior of the embedded sealing groove 17 and be squeezed and deformed to fill the interior of the embedded sealing groove 17. At the same time, the conical ring 20 enters the interior of the conical groove 18. The upward-extending slope of the conical groove 18 reduces the risk of leakage. After the combination is completed, the first flange ring 13 and the second flange ring 14 are fixed together by the fixing bolts 16, and the external pipe is connected to the inlet 11 and the outlet 12. At the same time, the temperature sensor 22 located at the bottom axis can accurately monitor the temperature, avoiding temperature errors caused by the sensor being close to the heating tube 8. The foam layer 27 and the aluminum foil layer 28 can reduce internal heat loss and reduce the heating interval.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
