Problems solved by technology
Since the double-axis motor needs to occupy a certain space, no air passes through the heat exchanger facing the double-axis motor, resulting in uneven air supply to the heat exchanger. Exposure while reducing user comfort
In the prior art, in order to increase the frontal area of the heat exchanger, it is necessary to keep a certain distance between the centrifugal fan and the heat exchanger, which increases the volume and installation difficulty of the fan system and increases the production cost

Embodiment Construction
[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] Such as Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a fan system, including: a heat exchanger, a centrifugal fan and a tuyere assembly 10 . The heat exchanger has an air inlet and an air outlet, and the air outlet is set opposite to the heat exchanger. The tuyere assembly 10 is disposed at the air outlet and extends toward the heat exchanger, and the diameter of the tuyere assembly 10 increases gradually along the extending direction.
[0022] By setting the tuyere assembly 10 whose diameter gradually increases along the extension direction, the air supply angle of the centrifugal fan can be increased through the tuyere assembly 10, so that the wind...

The invention provides a fan system and an air conditioner with the same. The fan system comprises a heat exchanger, a centrifugal fan and an air opening subassembly, wherein the centrifugal fan is provided with an air inlet and an air outlet; the air outlet is opposite to the heat exchanger; the air opening subassembly is arranged at the position of the air outlet and extends towards the heat exchanger; and the diameter of the air opening subassembly is increased gradually along the extension direction of the air opening subassembly. The fan system is provided with the air opening subassembly of which the diameter is gradually increased along the extension direction, the air supply angle of the centrifugal fan is increased through the air opening subassembly, so that the windward area of the heat exchanger is increased, and the purpose of increasing the windward area of the heat exchanger is achieved on the premise that the size and the mounting difficulty of the fan system are not changed.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to a fan system and an air conditioner with the fan system. Background technique [0002] The fan system of the existing central air-conditioning indoor air duct machine mostly adopts a biaxial motor, and a plurality of radial centrifugal fans are installed on the transmission shaft of the biaxial motor. Since the double-axis motor needs to occupy a certain space, no air passes through the heat exchanger facing the double-axis motor, resulting in uneven air supply to the heat exchanger. Exposure at the same time reduces user comfort. In the prior art, in order to increase the windward area of the heat exchanger, it is necessary to keep a certain distance between the centrifugal fan and the heat exchanger, which increases the volume and installation difficulty of the fan system and increases the production cost. Contents of the invention [0003] The present invention aims to pr...
