Abstract

The invention discloses an impeller, a fan with the impeller, and a cooking utensil. The impeller comprises a hub and multiple blades, wherein the hub is rotatably arranged on a support of the fan through a bearing; the multiple blades are arranged on the hub at intervals along the circumferential direction of the hub; each blade is divided into an outer forward blade area, an inner forward bladearea with the hub, and a backward blade area connected between the outer forward blade area and the inner forward blade area along the length direction; the extending directions of the air outlet sides of the blades in the inner forward blade areas and the outer forward blade areas are consistent to the rotating direction of the hub; and the extending directions of the air outlet sides of the blades in the backward blade areas are opposite to the rotating direction of the hub. According to the impeller provided by the embodiment of the invention, the blade areas with different extending directions are arranged on each blade, and the structural features of the different blade areas are different, so that the working noise is reduced on the basis of ensuring the higher air flow of the impeller.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an impeller, a fan and a cooking appliance with the same. Background technique [0002] Cooking appliances such as induction cookers and IH rice cookers are equipped with fans in the cooking appliances in order to improve heat dissipation efficiency. In the related art, the air flow rate of the impeller of the fan in the cooking appliances is small, and the working noise is relatively large, which seriously affects the user's use environment. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] For this reason, the present invention proposes an impeller, which has a high efficiency of doing work on the air during the working process, which is beneficial to increase the air flow rate and has low noise. [0005] The present invention also proposes a fan with the above-mentione...
