[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-5 A single-motor double-blade air duct structure comprises an auxiliary air duct A1, a main air duct 2, a blade A3, a motor 4, a blade B5, an auxiliary air duct B6, and an evaporator component 7. The motor 4 is a double-shaft motor, and one output shaft of the motor 4 is fixedly connected to the blade A3, the blade A3 is installed in the main air duct 2, the main air duct 2 is sleeved in the auxiliary air duct A1, the other output shaft of the motor 4 is fixedly connected to the blade B5, and the blade B5 is installed in the auxiliary air duct B6, and the auxiliary air duct B6 is installed in the auxiliary air duct A1. When the motor drives the blade B to rotate, the wind passing through the evaporator is axially sucked in by the blade, and the wind is sent into the main air duct through the channel of the auxiliary air duct B; when the motor drives the blade A to rotate, the wind passing through the evaporator is sucked in by the air inlets on both sides of the auxiliary air duct A, passes through the channel of the auxiliary air duct A, and reaches the center of the auxiliary air duct A, and the wind is axially sucked in by the blade A and blown out from the upper and lower air outlets of the main air duct.

[0026] In the present invention, the evaporator component 7 is located on the side of the fan blade B5 away from the fan blade A3. The wind passes through the evaporator component and then can be sucked into the fan blade B5.

[0027] In the present invention, the top and bottom of the main air duct 2 are both provided with openings, and the openings at the top and bottom are air outlets of the main air duct 2 for air outlet.

[0028] In the present invention, a connecting hole is provided on the side of the main air duct 2 close to the evaporator component 7, and the side of the auxiliary air duct B6 away from the evaporator component 7 is an air outlet, and the air outlet is arranged corresponding to the connecting hole. The connecting hole and the air outlet correspond to each other, which can facilitate the wind from the air outlet to flow into the connecting hole, that is, the wind flows into the main air duct 2 through the auxiliary air duct B.

[0029] In the present invention, first air outlets are provided at both ends of the auxiliary air duct A1 close to the evaporator component 7, and a second air outlet is provided at the center of the auxiliary air duct A1 close to the evaporator component 7. The first air outlet corresponds to the evaporator component 7, and the second air outlet is provided corresponding to the fan blade A3. The first air outlet can absorb the wind passing through the evaporator component 7 and suck the wind into the auxiliary air duct A1, and then transmit it into the main air duct 2 through the second air outlet.

[0030] In the present invention, the middle position of the main air duct 2 is a circular structure, and a through hole is opened at the center position of the main air duct 2. The function of the through hole is to facilitate the placement of the fan blade A.

[0031] In the present invention, the diameter of the fan blade A3 is greater than the diameter of the fan blade B5, so that the fan blade A3 and the fan blade B5 can be arranged adjacent to each other without interfering with each other.

[0032] In the present invention, the evaporator component 7 is an evaporator and a mounting bracket. The evaporator is mounted on the mounting bracket, and the mounting bracket is used to fix the evaporator.

[0033] In the present invention, a notch is provided at the center of the auxiliary air duct A1, and the middle circular structure of the main air duct 2 is installed on the notch of the auxiliary air duct A1. The notch facilitates the snap-on installation of the main air duct 2, so that the auxiliary air duct A1 and the main air duct 2 are stably connected.

[0034] In the present invention, the motor 4 is a double-shaft motor, and the model of the double-shaft motor is YSK370-4C8. Through the setting of the double-shaft motor, it is convenient to drive the fan blade A and the fan blade B at the same time.

[0035] In the present invention, the working principle is that when the motor drives the fan blade B to rotate, the wind passing through the evaporator is axially sucked in by the fan blade, and the wind is sent into the main air duct through the channel of the auxiliary air duct B; when the motor drives the fan blade A to rotate, the wind passing through the evaporator is sucked in by the air inlets on both sides of the auxiliary air duct A, passes through the channel of the auxiliary air duct A, and reaches the center of the auxiliary air duct A, and the wind is axially sucked in by the fan blade A, and blown out from the upper and lower air outlets of the main air duct. Therefore, the air duct structure with a single motor and two fan blades can increase the air supply volume and improve the utilization rate of the evaporator.
