Air-conditioner heat pump water heating machine for vehicle

Abstract

The invention discloses an air-conditioner heat pump water heating machine for a vehicle. The structure of the air-conditioner heat pump water heating machine comprises a liquid storing tank, a compressor and heat exchangers. The compressor is connected with the liquid storing tank through the heat exchangers. The two heat exchangers communicate with the compressor and the liquid storing tank correspondingly through connecting pipelines. A valve is installed in the connecting pipeline of one heat exchanger and the compressor. The valve comprises a thread groove, a through opening and a transition layer. The thread groove and the vertical extending end of the valve are connected through threads. The through opening and the transition layer are of an integrated structure. According to the machine, a heat absorbing device is additionally arranged in the transition layer in the valve, by the utilization of a heat absorbing plate, heat in hot water generated when the connecting pipelines donot refrigerate is concentrated to the heat absorbing plate partially, the heat can be dispersed from inside to outside, solidified coagulum outside the valve is heated and liquefied to flow out of the valve, and the situation that due to residual of the coagulum, aging of the valve is caused is avoided.

Description

technical field [0001] The invention relates to the field of air conditioner compressors, in particular to a heat pump water heater for vehicle air conditioners. Background technique [0002] The heat pump water heater air conditioner is a multi-purpose machine that combines a heat pump water heater and an air conditioner. While enjoying energy-saving hot water, you can enjoy free air conditioning. When not heating hot water, it is a separate air conditioning system; The heat pump hot water system is used to provide hot water. [0003] However, since the air conditioner heat pump water heater has more functions than the general air conditioner or heat pump water heater, and the functions are highly integrated, it requires a lot of pipeline layout. Due to the limited space of the vehicle, the existing vehicle heat pump water heater In order to meet the requirements of use, most of the valves are arranged to reduce the internal connecting pipelines.

[0003] However, since the air conditioner heat pump water heater has more functions than the general air conditioner or heat pump water heater, and the functions are highly integrated, it requires a lot of pipeline layout. Due to the limited space of the vehicle, the existing vehicle heat pump water heater In order to meet the requirements of use, most of the valves are arranged to reduce the internal connecting pipelines. When the vehicle passes through an area with a lot of dust distribution, the dust particles will enter the connecting pipelines and even the valves of the heat pump water heater through the gap between the vehicle body. On the other hand, as the dripping accumulates in the valve near the fuel tank and if it is not handled diligently, it will form solidification and remain on the valve, causing the valve to age and causing the pipeline connection to rupture and affect the use
