Electrically-assisted heating device of air conditioner

Abstract

The invention discloses an electrically-assisted heating device of an air conditioner, which is arranged at the upper side of an air outlet of a spiral case fan in a shell of an indoor unit of the air conditioner. The electrically-assisted heating device is in a grid type structure consisting of a plurality of electric hot plates and a plurality of fins which are longitudinally and horizontally crossed vertically and is provided with quadrate through holes. The electric hot plates are horizontally arranged at intervals, and the fins are longitudinally arranged at intervals so as to form the grid type structure. In the electrically-assisted heating device of the air conditioner, the electrically-assisted heating device is made into the grid type structure so as to play the role of rectification, and airflow coming out of the spiral case of the fan can exchange heat sufficiently and evenly with the electrically-assisted heating device. Meanwhile, because the electrically-assisted heating device is provided with a grid hole, impact noise generated by the indoor unit of the air conditioner due to the electrically-assisted heating device is completely avoided.

Description

technical field [0001] The invention relates to an air conditioner. In particular, it relates to an electric auxiliary heating device of an air conditioner capable of avoiding the impact noise generated by the electric auxiliary heating device of an air conditioner indoor unit. Background technique [0002] An air conditioner is a device that makes its internal refrigerant undergo a refrigeration or heating cycle consisting of a compression process, condensation process, expansion process, and evaporation process. When the air conditioner is in the refrigeration cycle, the refrigerant compressed by the compressor and turned into a high-temperature and high-pressure state can dissipate heat to the outside in the condenser, and when it flows through the expansion valve, its temperature and pressure are significantly reduced. When passing through the evaporator of the indoor unit, it absorbs heat, turns into a high-temperature and low-pressure refrigerant, and then flows back ...

Problems solved by technology

[0004] But the structure of existing electric auxiliary heating device 3 is a kind of integral plate structure, because the wind discharged from the outlet of volute fan 2 volute forms high-speed airflow, described high-speed airflow directly impacts on the The electric auxiliary heating device 3 at the outlet of the volute produces a lot of impact noise, increases the damping of the air conditioning system, and seriously affects the performance of the air conditioner
