Description

Technical Field

[0001] The invention belongs to the technical field of range hoods, and in particular relates to a range hood with optical fiber lighting. Background Art

[0002] Range hoods, as an indispensable device in modern kitchens, have lighting functions that are directly related to the convenience and safety of cooking operations. Traditional range hoods generally rely on tungsten filament bulbs located at the bottom for lighting. Although this design meets basic lighting needs to a certain extent, its limitations are becoming increasingly prominent. Insufficient light is the primary problem, and it is often difficult to illuminate the entire cooking area, affecting the chef's operating vision. In addition, the high energy consumption of tungsten filament bulbs is also a defect that cannot be ignored, which is contrary to the current social trend of energy conservation and emission reduction. Therefore, it has become an urgent problem to be solved in the industry to innovate the lighting methods of traditional range hoods to improve lighting effects and reduce energy consumption.

The outdoor sunlight is collected by setting the lighting structure and transmitted to the focusing lens for refracting and focusing, and finally the refracted and focused light is transmitted to the fiber optic lamp through the fiber optic channel, and the lighting brightness is high; by utilizing the light guiding property of the optical fiber for lighting, no additional electric energy conversion is required, and no heat and electromagnetic radiation are generated, which not only achieves the effect of saving electric energy, but also reduces the environmental pollution caused by electric energy conversion, which is in line with the modern green and environmentally friendly lighting concept.

[0007] Furthermore, two focusing lenses are arranged at intervals, the lighting structure is a light cover, and the two focusing lenses are arranged between the other end of the optical fiber line and the light cover; through such an arrangement, after the light is focused through multiple refractions, more light can be transmitted to the optical fiber lamp through the optical fiber channel, thereby improving the brightness of the optical fiber lamp.

[0008] Furthermore, the fiber optic lighting device also includes a protective shell with an opening on the upper side, the focusing lens is arranged in the protective shell, the light-collecting cover covers the upper opening of the protective shell, and the other end of the optical fiber passes through the bottom of the protective shell and is placed inside the protective shell; through such an arrangement, the protective shell can be used to prevent external factors from damaging or corroding the focusing lens, thereby ensuring the normal use of the focusing lens.

[0009] Furthermore, the air outlet at the top of the fan device is connected to the outdoors through a smoke exhaust pipe, and a rain shield is provided at one end of the smoke exhaust pipe located outdoors, and the protective shell is arranged on the top of the rain shield; through such an arrangement, by arranging the protective shell on the outdoor rain shield, an installation condition is provided for the lighting cover.

[0010] Furthermore, a smoke exhaust hood is provided on the top of the range hood body, and the optical fiber line extends into the range hood body through the inner side of the smoke exhaust hood. A wire trough box is fixedly provided in the smoke exhaust hood, and part of the optical fiber line is placed in the wire trough box. By so configuring, the wire trough box is provided to protect the optical fiber line and prevent it from being damaged.

[0011] Furthermore, the fiber optic lamp is arranged at the bottom of the range hood body; through such arrangement, the fiber optic lamp provides lighting effect for the cooking area below the range hood body.

[0012] Furthermore, a fume filter is provided inside the smoking port.

[0013] Furthermore, the lighting cover is hemispherical; by such an arrangement, it is ensured that the natural lighting can still meet the minimum requirements under conditions such as cloudy days when the natural lighting is not ideal.

[0014] Furthermore, the outer side of the optical fiber is covered with a protective sheath to prevent light leakage and protect the optical fiber. BRIEF DESCRIPTION OF THE DRAWINGS
