Embodiment 1

[0050] See figure 1 , figure 2 and image 3 , the present embodiment provides a volute 100, wherein the volute 100 includes a first air channel plate 110, a second air channel plate 120 and a side plate 130 disposed between them, the first air channel plate 110, An inner cavity is formed between the second air duct plate 120 and the side plate 130 , and a sound-absorbing assembly 200 capable of absorbing noise is provided on a side of the side plate 130 close to the inner cavity.

[0051] With such an arrangement, in the volute 100 , the inner cavity is used to place the impeller 300 , and the impeller 300 can generate noise during operation, so that the inner cavity is full of noise. Wherein, the noise in the inner cavity is absorbed by the sound-absorbing assembly 200, thereby reducing the noise in the inner cavity, and alleviating the technical problem in the prior art that the range hood has high noise during the operation of the fan.

[0052] In addition, since the so...

Embodiment 2

[0080] Embodiment 2 provides a fan. The fan includes the volute 100 of Embodiment 1. The technical features of the volute 100 disclosed in Embodiment 1 are also applicable to this embodiment. The technical features of the volute 100 disclosed in Embodiment 1 The description will not be repeated. The implementation of the blower will be further described in detail below in conjunction with the accompanying drawings.

[0081] See Figure 4 and Figure 5 , the fan provided in this embodiment includes an impeller 300, a motor 400, and the above-mentioned volute 100; wherein, the impeller 300 is arranged in the inner cavity of the volute 100, the motor 400 is connected to the volute 100 through a bracket 700, and the motor 400 drives and connects the impeller 300.

[0082] It should be added that, see image 3 , the side plate 130 is provided with an air outlet 131, the first air channel plate 110 is provided with a first air inlet 111, and / or, the second air channel plate 120 ...

Abstract

The invention relates to the technical field of kitchen appliances, in particular to a volute, a fan and a range hood. The volute comprises a first air duct plate, a second air duct plate and a side plate arranged between the first air duct plate and the second air duct plate, wherein an inner cavity is formed among the first air duct plate, the second air duct plate and the side plate; and a silencing assembly capable of absorbing noise is arranged on the side, close to the inner cavity, of the side plate. The fan comprises the volute. The range hood comprises the fan. According to the volute, the fan and the range hood provided by the invention, the technical problem that in the prior art, noise at the position of the fan is large in the running process of the range hood is solved.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a volute, a fan and a range hood. Background technique [0002] The range hood, also known as the range hood, is a kitchen appliance used to purify the kitchen environment. It can quickly extract the oily fume generated during the cooking process and discharge it outside to achieve the purpose of purifying the kitchen environment. [0003] The fan is the core component of the range hood. The fan generally includes a volute, a motor and an impeller. The motor drives the connected impeller, and the motor and the impeller are installed in the volute. When the fan is started, the motor rotates and drives the impeller to do work on the air in the volute, pushing the air to move along the volute, wherein, the direction of the air flow is changed through the volute and the air pressure is increased, so that there is a gap between the air inlet and the outlet of the volute.
