Abstract

The invention discloses a range hood. The range hood comprises an impeller and a volute. The volute is provided with an impeller containing cavity and comprises a volute outer plate and flow guide plates. The flow guide plates are arranged on the volute outer plate and correspond to the impeller. A preset angle exists between each flow guide plate and the volute outer plate. On the one hand, the flow guide plate can break the large vortex in airflow and improve the balance performance of the airflow, so that noise in the volute can be effectively lowered, and therefore the noise of the range hood can be lowered. On the other hand, the flow guide plate can guide the airflow to flow to an air outlet, so that the airflow is helped to flow smoothly and flow through the volute stably, and therefore the aerodynamic force of the airflow and the structure vibration of the volute can be lowered; and in this way, the noise of the range hood can be lowered, and the use comfort can be improved for users.

Description

technical field [0001] The invention relates to a range hood. Background technique [0002] With the improvement of people's living standards, people have new requirements for the home environment. As a must-have kitchen appliance for households, consumers require range hoods to have good comfort during use on the basis of ensuring performance. However, the huge noise produced by the range hood when it is running is very difficult for range hoods. For machines, noise is undoubtedly a huge problem. At this stage, major brands of range hoods have overcome the difficulties of suction and air volume one after another. The choice of consumers largely depends on the noise level of the products. There are more and more complaints about noise in the market, and the industry has been seeking new noise reduction solutions. However, considering the system and structure of the range hood itself, noise reduction is very difficult. [0003] The noise reduction methods of range hoods ar...
