Embodiment Construction

[0018] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0019] Such as figure 2 , image 3 As shown, the outdoor unit of the multi-unit air conditioner of the present invention includes a casing 1 in which a compressor 2, an outdoor heat exchange coil 3, a four-way reversing valve and a fan 4 are provided.

[0020] The fan 4 adopts a vertical cross-flow fan 4. The fan 4 includes a motor 5 and a cage drum 6 fixed to the output shaft of the motor 5. The cage drum 6 includes a plurality of horizontal hoops 7 of different heights and a plurality of The blades 8 evenly distributed in the axial direction, the outside of each blade 8 is fixed to the inside of the hoop 7, and the normal offset of each blade 8 with the hoop 7, that is, the blade 8 is not radially welded to the hoop 7 The inner side of the blade 8 is slightly deflected by an angle, but the angle at which each blade 8 is deflected is the same, and the welding...

Abstract

The invention discloses an outdoor unit of a multi-connected air conditioner. The outdoor unit comprises a housing (1), wherein a compressor (2), an outdoor heat exchanger coil (3) and a fan (4) are arranged in the housing (1), wherein the fan (4) is a vertically arranged cross flow fan (4), the fan (4) comprises an electric motor (5) and a cage-type roller (6) fixed to an output shaft of the electric motor (5), the cage-type roller (6) comprises multiple horizonal hoop rings (7) different in height and multiple blades uniformly distributed in the axial direction, the outer side of each blade is fixed to the inner side of the corresponding hoop ring (7), and each blade offsets from the normal direction of the hoop rings (7). The floor space of the outdoor unit of the multi-connected air conditioner can be decreased, and noise can be effectively reduced.

Description

Technical field [0001] The invention relates to the field of air conditioners, in particular to an outdoor unit of a multi-unit air conditioner. Background technique [0002] With economic progress and social development, multi-connected air conditioning units have become the main refrigeration equipment in commercial plazas, office buildings and other occasions. [0003] The outdoor unit of the multi-unit air conditioner is self-important. It is impossible to hang it on the wall bracket like the outdoor unit of the ordinary air conditioner. Instead, it must be placed on the air conditioning installation station of the building, and the installation station needs to occupy the building area of ​​the house. Yes, in this way, after a part of the building area is occupied by air conditioners, the use area of ​​the house is naturally reduced. [0004] The prior art multi-connection outdoor unit such as figure 1 As shown, in order to ensure the air volume and heat exchange, the axial fan...
