Cabinet-type air-conditioner indoor machine

Abstract

The invention relates to a cabinet-type air-conditioner indoor machine, which comprises a pedestal, a shell, a front framework, a front panel, a lower suction grid, a lateral suction grid, a filter, an indoor fan, an indoor heat exchanger and an electrical heater; and the electrical heater comprises a left fixed frame, a right fixed frame, a left rotating bracket, a right rotating bracket, a plurality of fins and a motor. When the heating operation of the cabinet-type air-conditioner indoor machine disclosed by the invention is carried out, the fins are in a horizontal state by utilizing the motor on the electrical heater, and because the frontal area of the fins is maximal, air flowing into the inner part of the indoor machine can be effectively heated; and when refrigerating operation is carried out, the fins on the cabinet-type air-conditioner indoor machine are in a vertical state, so that the wind quantity of circulating air can not be influenced, further, a larger wind quantity can be realized at a smaller rotating speed of the indoor fan, and energy consumption and noise can be greatly reduced.

Description

technical field [0001] The invention relates to a cabinet type air conditioner, in particular to an indoor unit of the cabinet type air conditioner. Background technique [0002] Generally, an air conditioner is a device that makes a refrigerant inside undergo a refrigeration or heating cycle consisting of a compression process, a condensation process, an expansion process, and an 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 first flows into the outdoor heat exchanger, where the refrigerant will dissipate heat to the outside, then flow to the expansion valve, and then flow through the expansion valve. The valve significantly reduces its temperature and pressure, and then this low-temperature, low-pressure refrigerant will flow into the indoor heat exchanger. In the indoor heat exchanger, the refrigerant will absorb the heat of the surroundi...

AI Technical Summary

Problems solved by technology

[0003] But, there is following problem in this cabinet type air conditioner indoor unit of prior art: As mentioned above, because the multiple fins 18 on the electric heater 15 are fixedly arranged side by side along the horizontal direction, and the gap between the fins 18 The gap is small, so the frontal area of ​​these fins 18 is always at the maximum state during cooling operation, which will not only affect the air volume of the indoor unit due to the excessive resistance to the inhaled indoor air, but also increase the air conditioner capacity. energy consumption and noise
