[0022] The application will be further described below in combination with the embodiments, but is not limited to the contents of the description.

[0023] For example, Figure 1 and Figure 2As shown, the air duct machine provided by the present application comprises a shell 1; a mounting plate 4 fixedly arranged in the shell 1, and the mounting plate 4 divides the shell 1 into a first chamber 11 and a second chamber 12; and a fan 2 rotatably arranged on the mounting plate 4, and the fan 2 has a first orientation for making gas flow from the first chamber 11 to the second chamber 12 and a second orientation for making gas flow from the second chamber 12 to the first chamber 11. The mounting plate 4 is fixedly arranged to directly divide the shell 1 into the first chamber 11 and the second chamber 12, and the fan 2 is rotated to change the flow direction of the gas between the first chamber 11 and the second chamber 12, thereby effectively overcoming the problem of high complexity of the baffle structure in the prior art due to the rotation of the fan 2.

[0024] The shell 1 is provided with a side air outlet 13 and a lower air outlet 14, the first chamber 11 is connected with the side air outlet 13, and the second chamber 12 is connected with the lower air outlet 14. The gas entering the shell 1 can flow through the side air outlet 13, the first chamber 11, the second chamber 12 and the lower air outlet 14 in sequence to realize vertical air outlet, or flow through the lower air outlet 14, the second chamber 12, the first chamber 11 and the side air outlet 13 in sequence to realize horizontal air outlet.

[0025] The mounting plate 4 is provided with a mounting opening 41, one end of the mounting opening 41 is communicated with the first chamber 11, the other end of the mounting opening 41 is communicated with the second chamber 12, and the fan 2 is rotatably arranged at the mounting opening 41.

[0026] The fan 2 is arranged in the first chamber 11, and part of the fan 2 is located in the second chamber 12. The air inlet or air outlet of the fan 2 is located in the second chamber 12, so that the gas flow in the shell 1 can only flow in the first chamber 11 and the second chamber 12 through the fan 2, and the mounting plate 4 can also separate the two air inlets or air outlets of the fan 2, thereby avoiding the backflow phenomenon between the two air inlets or air outlets of the fan 2 and affecting the efficiency of the fan 2.

[0027] A sealing structure is arranged between the mounting plate 4 and the inner surface of the shell 1. The sealing structure completely isolates the first chamber 11 and the second chamber 12, so that the gas flow in the first chamber 11 and the second chamber 12 can only flow through the fan 2, thereby ensuring the driving effect of the fan 2.

[0028] The duct type air conditioner further comprises a heat exchanger arranged in the first chamber 11 or the second chamber 12. According to different requirements, the heat exchanger is arranged in the second chamber 12 when the heating working condition required by the environment where the duct type air conditioner is located is longer than the cooling working condition, so that the duct type air conditioner preferentially ensures the operation of the heating working condition, and the air flow of the fan 2 is directly discharged from the shell 1 after being heated by the heat exchanger, thereby ensuring the hot air volume of the lower air outlet 14; conversely, when the cooling working condition required by the environment where the duct type air conditioner is located is longer than the heating working condition, the heat exchanger is arranged in the first chamber 11, so that the duct type air conditioner preferentially ensures the operation of the cooling working condition, and the air flow of the fan 2 is directly discharged from the shell 1 after being cooled by the heat exchanger, thereby ensuring the cold air volume of the side air outlet 13.

[0029] In the first orientation, the side air outlet 13 serves as the air outlet of the duct type air conditioner, and the lower air outlet 14 serves as the air inlet of the duct type air conditioner, at this time, the duct type air conditioner is in the air flow state of lower air inlet and side air outlet, and can achieve the purpose of waterfall cooling in cooling; in the second orientation, the lower air outlet 14 serves as the air outlet of the duct type air conditioner, and the side air outlet 13 serves as the air inlet of the duct type air conditioner, at this time, the duct type air conditioner is in the air flow state of side air inlet and lower air outlet, and can quickly blow hot air to the ground to achieve the purpose of rapid heating in heating.

[0030] The number of the fans 2 is at least two, and all the fans 2 are rotatably arranged on the mounting plate 4. Preferably, the fans 2 correspond to the mounting ports 41 one by one. That is, a plurality of separate mounting ports 41 are formed on the mounting plate 4, thereby reducing the cutting area of the mounting plate 4 and ensuring the structural stability of the mounting plate 4 under the premise that all the fans 2 can reliably rotate.

[0031] All the fans 2 are sequentially connected, all the fans 2 can rotate and change the orientation of the air outlet at the same time, and the rotation axes of all the fans 2 are collinear. This ensures that all the fans 2 can be adjusted in place at the same time when the air outlet direction of the duct type air conditioner is adjusted, thereby avoiding the problem of turbulence in the duct type air conditioner caused by different air outlet directions of the fans 2.

[0032] The fan 2 is a mixed flow fan.

[0033] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments cannot be exhausted. Any obvious changes or variations derived from the technical solutions of the present application still fall within the protection scope of the present application.
