Window air conditioner comprising outdoor fan with two water-kicking rings

Abstract

The invention discloses a window air conditioner comprising an outdoor fan with two water-kicking rings. The window air conditioner is characterized in that outdoor heat exchangers comprise an outer outdoor heat exchanger and an inner outdoor heat exchanger, and the outdoor fan is arranged at the middle of the outer outdoor heat exchanger and the inner outdoor heat exchanger and provided with the two water-kicking rings; and seal-plates are arranged above or at the two sides of a space formed by the outer outdoor heat exchanger and the inner outdoor heat exchanger so as to seal the outdoor fan in the space surrounded by the seal-plates, and the shaft of a motor passes through the inner outdoor heat exchanger to drive the outdoor fan to rotate. In the invention, the two water-kicking rings of the outdoor fan can greatly increase the water-kicking effect, which is more advantageous to the heat dissipation of the outdoor heat exchangers. Because the outdoor heat exchangers are arranged separately, the heat dissipation of the outdoor heat exchangers is evener, and the heat dissipation is more sufficient under the same situations; and the system resistance is reduced, which is helpful for improving the energy efficiency ratio (EER) of the whole machine.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a window type air conditioner with an outdoor side fan and double water rings. Background technique [0002] Such as figure 1 As shown, the structure of the window air conditioner designed in the prior art is: chassis 1 constitutes the bottom surface of the air conditioner, and a front panel 3 is arranged in front of the indoor side of chassis 1 . [0003] An air intake structure 3i for sucking indoor air is formed at the lower end of the front panel 3, and an exhaust grill 3e is provided at the upper end for discharging heat-exchanged air into the room. Moreover, several exhaust holes 3e' for exhausting air into the room are provided on the exhaust grill 3e. [0004] Simultaneously, the air suction grid 4 is set in the front of the air suction structure 3i, and several air suction holes 4' for sucking air are set on the air suction grid 4, A filter is set between (not shown in the figure...

AI Technical Summary

Problems solved by technology

[0018] However, in the window air conditioner with the above structure, since there is only one water pumping ring on the outdoor fan 32, the amount of water pumped out is limited, and no water can be pumped from the top of the outside outdoor heat exchanger 34, so the effect of pumping water is not good.

In addition, if two rows of outdoor heat exchangers are installed together, the air resistance is very large, and the heat exchange effect of the inner outdoor heat exchanger 44 is very poor.
