DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings.

[0017] Figure 1-3 As shown, the column cabinet type top-outlet fresh air air conditioner of the present invention comprises a fresh air component arranged in the top cavity of the column cabinet air conditioner 7, the fresh air component comprises a centrifugal fan 1 and an air inlet bracket 2, the centrifugal fan 1 is fixed to the middle of the rear frame 4 of the air conditioner through a mounting frame 3, the air inlet bracket 2 is installed at the bottom center of the rear frame 4, an air inlet pipe 21 is arranged in the middle of the air inlet bracket 2, the air inlet in the middle of the centrifugal fan 1 faces the air inlet pipe 21 on the air inlet bracket 2, and the air outlet is connected to the fresh air outlet 41 on the side of the rear frame 4. The working process of the present invention is: when installing, the air inlet pipe 21 is passed through the wall to the outside, and when in use, it can be operated independently or simultaneously with the air conditioner, and the fresh air component sends the fresh air outdoors into the room through the air inlet pipe 21 under the blowing action of the centrifugal fan 1.

[0018] Since the fresh air outlet 41 is located on the side of the air conditioner rear frame 4, it can effectively prevent the fresh air from blowing directly at people, improving comfort. In addition, the fresh air outlet 41 is placed on the top, which can effectively prevent mosquitoes, mice, etc. from crawling into the fresh air duct, thus protecting the equipment. At the same time, the fresh air inlet pipe 21 is installed on the top, which can form a vertical synergistic fixing effect with the air conditioner internal and external unit connecting pipe 6 installed at the bottom, making the whole machine more stable after assembly.

[0019] The specific structure of the centrifugal fan 1 is that it includes a motor 11, a motor cover 12, a centrifugal fan 13, a front volute 14 and a rear volute 15. The motor cover 12 fixes the motor 11 on the front volute 14, the centrifugal fan 13 is installed on the main shaft of the motor 11, and the front volute 14 and the rear volute 15 are fixed together to cover the centrifugal fan 13 to form a volute-shaped air duct structure. By setting the volute-shaped air duct structure, noise can be reduced, and fresh air can be guided to enter from the air inlet pipe 21 and blown out from the fresh air outlet 41 on the side of the air conditioner, thereby improving the working efficiency of the fresh air component, while ensuring the compactness of the overall structure and avoiding occupying too much air conditioning space.

[0020] As for the air inlet bracket 2, considering the integrity of the appearance of the column cabinet air conditioner, the air inlet bracket 2 is preferably a part of the rear frame 4 shell, that is, it is kept flush with the air conditioner rear frame 4 after installation. For the convenience of installation and maintenance, it can be connected to the rear frame 4 by screws. For the convenience of connecting the air inlet pipe 21, a pipe interface is provided in the middle of the air inlet bracket 2, and the air inlet pipe 21 is fixed to the pipe interface by a clamp.

[0021] Furthermore, it also includes a filter bracket 5, on which a detachable filter 51 is provided, a guide groove 31 is provided on the side of the mounting frame 3 away from the centrifugal fan 1, and an opening 22 is provided on the side of the air inlet bracket 2, and the filter bracket 5 can be pushed into the guide groove 31 through the opening 22. The filter bracket 5 and the filter 51 can filter the inhaled fresh air to ensure the cleanliness of the fresh air entering the room. The filter bracket 5 is installed in a pull-out manner, which is convenient for cleaning and replacement, and improves the convenience of use.

[0022] Regarding the connection method between the filter 51 and the filter bracket 5, considering that the filter 51 is relatively thick, in order to ensure the convenience and stability of installation, a receiving groove 52 with a top opening is provided on the filter bracket 5, and the front and rear sides of the receiving groove 52 are hollow structures. The filter 51 is placed in the receiving groove 52 through the top opening.

[0023] The present invention arranges the fresh air component in the top cavity of the column cabinet air conditioner, and the fresh air is blown out from the top side of the rear frame, which can effectively prevent the blown fresh air from blowing directly on people and improve comfort. The fresh air outlet is placed on the top, which can effectively prevent mosquitoes, mice and the like from crawling into the fresh air duct, thereby protecting the equipment. At the same time, the fresh air inlet duct is installed on the top, which can form a coordinated fixing effect up and down with the connecting pipes of the indoor and outdoor units of the air conditioner installed at the bottom, so that the whole machine is more stable after assembly, and has a good practical application prospect.
