Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as Figure 1~6 As shown, the fan system of the range hood in this embodiment includes a fan housing 1, a motor 2, an impeller 3 and a magnetic levitation assembly 4, the motor 2 is arranged on the fan housing 1, and the impeller 3 is connected to the output shaft 21 of the motor 2, The outer peripheral wall of the motor 2 is provided with an assembly edge 22, and the magnetic levitation component 4 is used to install the motor 2 on the fan casing 1 and keep a gap between the motor 2 and the fan casing 1, even if the body of the motor 2 is always in a suspended state .

[0028] In this embodiment, the magnetic levitation assembly 4 includes a locking member 41, a first levitating magnetic ring 42, a second levitating magnetic ring 43, and an elastic pad 44. The outer circumference of the first levitating magnetic ring 42 is concave...

Abstract

The invention relates to a fan system of an extractor hood. The fan system comprises a fan shell, a motor, an impeller and a magnetic suspension assembly. The motor is arranged on the fan shell. An assembly edge is arranged on the peripheral wall of the motor. The magnetic suspension assembly comprises a locking part, a first magnetic suspension ring and a second magnetic suspension ring, whereinthe magnetisms of the first magnetic suspension ring and the second magnetic suspension ring repel each other. An annular groove arranged in the circumferential direction is formed in the periphery ofthe first magnetic suspension ring in a concave manner. The second magnetic suspension ring is arranged on the periphery of the first magnetic suspension ring in a sleeving manner and is located in the annular groove. Suspension space is formed between the first magnetic suspension ring and the second magnetic suspension ring. A first assembly hole through in the axial direction is formed in thefirst magnetic suspension ring. The locking part penetrates through the first assembly hole to fix the magnetic suspension assembly to the fan shell. A clamp groove capable of clamping the assembly edge is arranged on the peripheral wall of the second magnetic suspension ring. The second magnetic suspension ring provided with the assembly edge is suspended in the suspension space all the time, andtherefore a motor body keeps suspended all the time, and vibration and noise generated by the motor in the running process of the fan system are effectively reduced.

Description

technical field [0001] The invention relates to a fan system for a range hood, in particular to a shock-absorbable fan system for a range hood. Background technique [0002] At present, the range hood has become one of the essential kitchen equipment for ordinary families. When the range hood is working, the range hood is sucked and exhausted through the operation of the fan. The vibration and noise of the fan system mainly come from the aerodynamic noise generated when the impeller rotates. , and mechanical vibration and noise caused by unstable air flow and poor dynamic balance of the impeller. In order to reduce the noise generated when the fan system is working, in the existing range hood fan system, since the impeller and the impeller center plate are rigidly connected, and the impeller center plate is rigidly connected to the motor shaft, the entire fan system is often connected through the motor and the casing. The shock-absorbing pads between them can realize the sh...
