Description

Technical Field

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

[0002] Range hoods, also known as range hoods, are kitchen appliances used to purify the kitchen environment. They can quickly extract the exhaust gas generated by stove combustion and the fumes generated during cooking, and discharge them outdoors to achieve the purpose of purifying the kitchen environment. With the progress of human civilization, in the field of daily stoves and range hoods, the shielding, separation and discharge of fumes have become more and more serious due to the improvement of the airtightness of modern rooms and people's increasing requirements for living environment. Range hoods can be divided into two categories: 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. According to the number of motors and wind wheels, they can be divided into: double machines and single machines (i.e. double cylinders and single cylinders). From the accumulation and drainage method, they can be divided into double oil circuits and three oil circuits (gas chamber drainage, protective cover drainage and wind-transported drainage). From the perspective of smoke collection chamber structure, there are single-layer (three oil circuits), double-layer inner-layer (two oil circuits), multi-layer collection network (multiple oil circuits), etc. From the perspective of functional structure, it can be divided into multimedia range hoods, embedded range hoods, wall-suction range hoods, side-suction range hoods, solid wood range hoods, etc.

[0003] In existing range hoods, the guide plate of the range hood is generally fixed on the panel, which not only takes up kitchen space, but also keeps the smoke outlet open all the time, which not only affects the appearance of the range hood, but also easily emits odors in the range hood, affecting the kitchen air quality. In modern urban housing, most of them use public exhaust ducts, which easily cause oil smoke to flow back and pollute the indoor air.

[0004] In the "A range hood with a movable panel that can open and close automatically" with announcement number CN 202171274 U, the movable panel is automatically opened and closed to prevent the backflow of oil smoke and the emission of odor in the range hood, thereby maintaining the beautiful appearance of the range hood. However, when the movable panel is opened and closed, there is a gap between the movable panel and the front panel, and the oil at the lower edge of the front side of the air intake port will drip down along the inner wall of the front panel.
