Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an oil guide structure and a range hood having the same. Background Art

[0002] The range hood, also known as the range hood or smoke extractor, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste from the stove combustion and the oil smoke generated during the cooking process that is harmful to the human body and discharge it outdoors. At the same time, it condenses and collects the oil smoke to reduce pollution, purify the air, and has a safety guarantee function of anti-toxicity and explosion-proof. The range hood needs to be cleaned regularly. Simple cleaning cannot remove the oil stains. Professional cleaning agents must be used to clean the range hood.

[0003] Range hoods can be divided into two categories based on their appearance: European and Chinese. European range hoods are mainly wall-mounted, and there are also some high-end island-style products; Chinese range hoods are mainly wall-mounted, with deep hoods and shallow hoods. Based on the number of motors and wind wheels, they can be divided into: double machines and single machines (i.e. double cylinders and single cylinders). Based on the oil collection method, they can be divided into double oil circuits and three oil circuits (air chamber oil collection, protective cover oil collection and wind transport oil collection). Based on the smoke collection chamber structure, they can be divided into single-layer (three oil circuits), double-layer inner-layer (double oil circuits), multi-layer collection network (multiple oil circuits), etc. Based on the functional structure, they can be divided into multimedia range hoods, embedded range hoods, wall-suction range hoods, side-suction range hoods, solid wood range hoods, etc.

[0004] After the existing range hood is used for a long time, a lot of oil accumulates inside the air collecting box. When the oil accumulates too much, some of the oil will drip directly onto the oil collecting plate at the bottom of the panel in the form of raindrops. The oil dripping directly on the oil collecting plate can easily produce noise from the oil dripping due to the large dripping distance, which causes discomfort. Utility Model Content
