Problems solved by technology

At present, the main air duct of integral air-conditioning products is a centrifugal air duct. When the motor rotates at a high speed in this type of air duct, a large pressure difference is generated on both sides of the volute tongue of the volute, and the airflow forms a vortex at both ends of the volute tongue. Increased noise, poor user experience

Embodiment Construction

[0025] see in combination Figure 1 to Figure 4 As shown, according to an embodiment of the present application, a volute assembly includes:

[0026] A volute 3, the volute 3 includes: a first airflow channel and a second airflow channel;

[0027] The airflow direction in the first airflow channel is the first direction, the airflow direction in the second airflow channel is the second direction, and the angle θ between the first direction and the second direction is: 90°<θ ≤180°.

[0028] Two airflow channels are arranged in the volute 3, and the angle between the two airflow directions is at an obtuse angle. The airflow in one direction has a balancing effect on the airflow in the other direction, which can reduce the noise caused by vibration.

[0029] In some embodiments, the volute assembly further includes a fan blade 2, and the fan blade 2 is arranged on the volute 3 and is located at the intersection of the first airflow channel and the second airflow channel.

The volute assembly includes a volute, and the volute includes: a first airflow passage and a second airflow passage; the airflow direction in the first airflow passage is the first direction, and the airflow direction in the second airflow passage is the second airflow passage Two directions, the angle θ between the first direction and the second direction is: 90°

Description

technical field [0001] The application belongs to the technical field of air conditioning systems, and in particular relates to a volute assembly, an air supply assembly and an air conditioning system. Background technique [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for the use of household appliances. At present, the main air duct of integral air-conditioning products is a centrifugal air duct. When the motor rotates at a high speed, a large pressure difference is generated on both sides of the volute tongue of the volute, and the airflow forms a vortex at both ends of the volute tongue. Increased noise and poor user experience. SUMMARY OF THE INVENTION [0003] Therefore, the technical problem to be solved by the present application is to provide a volute assembly, an air supply assembly and an air conditioning system, which can reduce wind noise. [0004] In order to solve the above problems, the pr...
