Window-type air conditioner

Abstract

The invention discloses a window-type air conditioner, which comprises an indoor panel, a case, an evaporator, an indoor fan, a condenser, an outdoor fan, a compressor and a base plate; an upper centrifugal fan is selectively separated from a fan motor shaft; when the upper centrifugal fan is separated from the fan motor shaft, a lower centrifugal fan runs and the upper centrifugal fan stops; and when the upper centrifugal fan is connected with the fan motor shaft, the upper centrifugal fan and the lower centrifugal fan synchronously run under the drive of a fan motor. When the upper centrifugal fan is separated from the fan motor shaft, the lower centrifugal fan runs, the upper centrifugal fan stops, air enters the case from an air inlet grid at the bottom of the case, the air pressure in the case rises, and a part of air outwards flows from the air inlet grid on the upper wall of the case, so that falling leaves and sundries covered at the upper air inlet grid can be blown away, and the air inlet capacity of the upper air inlet grid is recovered.

Description

technical field [0001] The present invention relates to the technical field of window-type air conditioners, in particular to an outdoor fan that uses a superimposed centrifugal fan, and the upper centrifugal fan can be detached from the fan motor shaft, thereby blowing the fallen leaves attached to the air intake grille on the top of the cabinet. Go, a window air conditioner that guarantees the heat exchange capacity of the outdoor part. Background technique [0002] Generally, an air conditioner is a device that cools or heats an indoor environment to create a comfortable indoor environment, and is roughly classified into an integrated type air conditioner and a split type air conditioner. [0003] Although the functions of the integrated air conditioner and the split air conditioner are the same, the integrated air conditioner is equipped with cooling and heat dissipation components in the same casing, and is installed on the wall or on the window through the wall. The a...

AI Technical Summary

Problems solved by technology

[0009] In the above-mentioned window air conditioners of the prior art, the air flow direction generated by the outdoor fan of the first air conditioner has a clear directionality, and when the air flows through the condenser, it only has efficient heat dissipation capacity within the range corresponding to the size of the fan , cannot make full use of the overall heat exchange area of ​​the condenser; in the second type of air conditioner, the outdoor air intake grille on the chassis is set on the top of the chassis, and fallen leaves or flaky debris often fall on the top of the chassis, and are caught on the top of the chassis. The suction of the centrifugal fan is adsorbed to the position of the air intake grill, and then covers the opening of the air intake grill, greatly reducing the air intake of the upper centrifugal fan, thereby affecting the heat exchange efficiency of the condenser and reducing the overall cooling capacity of the air conditioner
