Abstract

The invention discloses an air duct structure, a fan and an electric oven. The air duct structure comprises a lampblack conveying air duct provide with a lampblack inlet in one end and provided with alampblack outlet in the other end. The area of the lampblack inlet is larger than that of the lampblack outlet, the lampblack outlet is located in the axle wire of the lampblack inlet and the lampblack conveying air duct is arranged in a restraining manner between the two tail ends of the lampblack inlet and the lamp black outlet, so that the lampblack conveying paths from two ends of the lampblack inlet to the lampblack outlet are equal, separately. The air duct structure disclosed by the invention is simple in integral structure and has relatively excellent lampblack collecting ability andlampblack conveying effects.

Description

Technical field [0001] The invention relates to household appliances, in particular to an air duct structure, a fan and an electric oven. Background technique [0002] The cooking fume contains many harmful substances including acrolein, benzene, formaldehyde, crotonaldehyde, etc. The cooking fume produced during the cooking process needs to use a cooking fume system to reduce the cooking fume being inhaled, and at the same time, the collection and separation of the cooking fume reduce or even avoid direct cooking fume Discharging into the air is also the current environmental protection regulation. [0003] Electric oven is a commonly used barbecue tool, but a lot of oily smoke will be generated during the barbecue. Conventional electric ovens generally do not deal with oil fume, or have a direct-exhaust smoke system, and harmful oil fume will be directly discharged into the air. For example, Chinese Patent CN201720943392 discloses a healthy barbecue grill with a built-in range ...
