Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1-3, the column cabinet type top air-out fresh air conditioner of the present invention comprises a fresh air component arranged in a cavity at the top of a column cabinet air conditioner 7, wherein the fresh air component comprises a centrifugal fan 1 and an air inlet support 2, the centrifugal fan 1 is fixed in the middle of a rear frame 4 of the air conditioner through an installation frame 3, the air inlet support 2 is installed in the center of the bottom of the rear frame 4, an air inlet pipe 21 is arranged in the middle of the air inlet support 2, an air inlet in the middle of the centrifugal fan 1 is opposite to the air inlet pipe 21 on the air inlet support 2, and an air outlet is communicated with a fresh air. The working process of the invention is as follows: when the air conditioner is installed, the air inlet pipe 21 penetrates through a wall body and leads to the outdoor, when the air conditioner is used, the air conditioner can independently operate or simultaneously operate with the air conditioner, and the fresh air component sends outdoor fresh air into the indoor through the air inlet pipe 21 under the blowing effect of the centrifugal fan 1.

Because the fresh air outlet 41 is positioned on the side surface of the air conditioner rear frame 4, the blown fresh air can be effectively prevented from blowing directly towards people, and the comfort is improved. And fresh air outlet 41 top-mounted can prevent effectively that mosquito mouse etc. from climbing into the new trend wind channel in, play the guard action to equipment, simultaneously, fresh air-supply line 21 is installed at the top, can form upper and lower fixed action in coordination with the interior quick-witted connecting pipe 6 of air conditioner of installing in the bottom for the complete machine is more firm after the assembly

The centrifugal fan 1 has a specific structure that the centrifugal fan comprises a motor 11, a motor cover 12, a centrifugal fan 13, a front volute 14 and a rear volute 15, wherein the motor cover 12 fixes the motor 11 on the front volute 14, the centrifugal fan 13 is installed on a main shaft of the motor 11, and the front volute 14 and the rear volute 15 are fixed together and cover the centrifugal fan 13 to form a volute-shaped air duct structure. Through setting up the wind channel structure of volute form, the noise can be reduced to guide the new trend to get into from air-supply line 21, blow out from the new trend export 41 of air conditioner side, improve the work efficiency of new trend subassembly, guarantee overall structure's compactedness simultaneously, avoid occupying too many air conditioner spaces.

For the air intake bracket 2, considering the integrity of the appearance of the post cabinet air conditioner, the air intake bracket 2 preferably employs a portion of the housing of the rear frame 4, i.e., remains flush with the air conditioner rear frame 4 after installation. For convenient installation and maintenance, the rear frame 4 can be connected with the rear frame through screws. In order to conveniently connect the air inlet pipe 21, a pipeline connector is arranged in the middle of the air inlet support 2, and the air inlet pipe 21 is fixed on the pipeline connector through a hoop.

Further, still include filter screen support 5, be equipped with detachable filter screen 51 on filter screen support 5, one side that centrifugal fan 1 was kept away from to mounting bracket 3 is equipped with guide slot 31, the side of air inlet support 2 is equipped with opening 22, filter screen support 5 accessible opening 22 pushes into in the guide slot 31. The filter screen bracket 5 and the filter screen 51 are arranged to filter the sucked fresh air, so that the cleanliness of the fresh air entering the room is guaranteed. The filter screen support 5 is installed in a drawing mode, so that the cleaning and the replacement are convenient, and the use convenience is improved.

To filter screen 51 and filter screen support 5's connected mode, consider that filter screen 51 is thick, for convenience and the stability of guaranteeing the installation be equipped with open-top's holding tank 52 on filter screen support 5, both sides are hollow out construction around the holding tank 52, filter screen 51 places in holding tank 52 through open-top.

The novel air inlet pipe is arranged at the top and can form an up-and-down cooperative fixing function with the connecting pipe of the air conditioner inner machine and the air conditioner outer machine arranged at the bottom, so that the whole machine is more stable after being assembled, and the novel air inlet pipe has a good practical application prospect.
