Integrated air energy water heater water tank

Abstract

The invention relates to an integrated air energy water heater water tank. The water tank comprises an outer cylinder, an inner container mounted in the outer cylinder, a coil pipe mounted in the inner container and a foaming thermal insulation layer arranged between the outer cylinder and the inner container in a filling mode, wherein the space between the outer cylinder and the inner container is filled up with foaming liquid in the foaming thermal insulation layer, a refrigerant circulates in the coil pipe, the two ends of the coil pipe both extend out from the top of the inner container, asupporting locating plate is fixedly mounted above the inner container and is wrapped in the foaming thermal insulation layer, a plurality of connecting bolts are fixedly mounted on the supporting locating plate, each connecting bolt is in threaded connection with a nut after penetrating through the supporting locating plate and the top of the outer cylinder sequentially, and the lower end of each nut abuts against the upper end face of the outer cylinder. According to the water tank, the coaxiality between the outer cylinder and the inner container is realized through the supporting locatingplate, the foaming layer is uniformly distributed between the outer cylinder and the inner container, and the performance of a whole machine is improved.

[0002] With the popularization and application of low-temperature and ultra-low temperature heat pump compressors, and the rapid advancement of the national coal-to-electricity plan, more and more families choose air-energy water heaters for their domestic hot water supply. At present, split-type air-energy water heaters are more common. It is separated from the water tank and connected by connecting pipes of different lengths according to the installation environment. The manufacturing process of the host and the water tank is simple, and the host of different specifications can be adapted to water tanks of different specifications. It has high versatility and interchangeability and effectively reduces Widen the range of products and reduce the cost of development, manufacturing and management, but it occupies a large space, the connecting pipe is long, and the heat loss is serious

However, with the rise of housing prices and the shortage of land, the integrated air-energy water heater (referred to as the all-in-one machine) that integrates the host and the water tank is more and more popular among the masses. The hot line pipes and temperature control pipes are led out from the upper end of the outer cylinder of the water tank. It is difficult to fix the position of each pipe, and it is difficult to match the through hole of the barrel lid with the above pipes after foaming. Increase the matching gap between the pipe and the hole, but considering the convenience of assembly, the position of the pipe connection is poor, resulting in the pipe being easily skewed, flattened, poor connection quality, high vibration and noise of the whole machine, reduced performance, and messy appearance , not beautiful; and the connection and fixation of the main engine and the water tank, the main engine is generally installed on the outer cylinder cover by screws. During transportation, due to the heavy weight of the main engine and the thin wall of the outer cylinder cover, the swing of the main engine is transmitted to the outer cylinder cover by screws On the other hand, pulling the outer cylinder cover will cause distortion of the outer cylinder cover, deformation of the connecting screw holes of the upper wall, the outer cylinder, and the outer cylinder cover, and other problems, which will cause great hidden dangers in quality
