Description

Technical Field

[0001] The utility model relates to the field of air energy water heaters, in particular to an inner tank structure of an air energy water heater. Background Art

[0002] Air energy water heater, also known as "air source heat pump water heater", has a working principle very similar to that of air conditioner. It uses a small amount of electricity to drive the compressor. The high-pressure liquid working fluid evaporates into gas in the evaporator after passing through the expansion valve, and absorbs a large amount of heat energy from the air; the gaseous working fluid is compressed by the compressor into a high-temperature, high-pressure liquid, and then enters the condenser to release heat and heat the water... This continuous cycle of heating can heat the water to 50℃~65℃.

[0003] The existing air source heat pump water heater inner tank structure uses a copper coil connected to the water tank inner tank through a thermal conductive adhesive, which has low thermal conductivity and high manufacturing cost.

[0004] After searching the existing Chinese patent: a new air source heat pump water heater water tank liner structure (Announcement No.: CN203413827U), including a water tank jacket, a water tank liner, a head, a sewage outlet, a water inlet, a refrigerant outlet, a refrigerant inlet, a temperature probe port, and a water outlet. The water tank liner structure adopts an integral jacket structure, and the water tank jacket is formed into a spiral flow channel through process molding. The concave part of the water tank jacket is connected to the inside or outside of the water tank liner through a welding process, thereby forming a firm and reliable contact. The new structure replaces the traditional copper coil with an integral jacket structure made of steel, and adopts a mature welding process to replace the traditional thermal conductive adhesive connection process between the copper coil and the water tank liner. This new air source heat pump water heater water tank liner structure greatly reduces the manufacturing cost while improving the thermal conductivity.

[0005] The above patent adopts an integral jacket structure to form a firm and reliable contact between the inner liner and the water tank. However, the device has a disadvantage that the water tank inner liner is welded to the inner side of the water tank. Once the components inside the water tank inner liner are damaged, the inner liner cannot be disassembled and repaired, which makes it difficult to repair the equipment.

[0006] Therefore, it is necessary to invent an air energy water heater inner tank structure to solve the above problems. Utility Model Content
