TECHNICAL FIELD
[0001] The present application relates to the field of oil fume equipment, in particular to a flat plate range hood capable of adjusting the height of the air inlet. BACKGROUND
[0002] The range hood is a kind of household appliance for discharging cooking fume gas and purifying the kitchen environment. When working, the main motor drives the fan to rotate to generate air flow, and the air flow is guided by the body assembly to generate a negative pressure area at the air inlet to absorb the fume gas, and then discharged to the outdoor from the air outlet.
[0003] A flap is installed at the air inlet to achieve better smoke gathering effect, but in the existing technology, the air inlet height of the range hood with the flap is fixed, which is difficult to adapt to high cooking utensils. When the flap is opened or closed, it is easy to collide and overturn the cooking utensils, causing danger. For low cooking utensils, the flap is too high to form a good smoke gathering effect, resulting in the escape of fume gas. On the other hand, a single air inlet cannot avoid the overflow of fume gas that has not been sucked in. SUMMARY
[0004] In order to solve the above technical problems, the present application provides a flat plate range hood capable of adjusting the height of the air inlet, and simultaneously provides upper and lower air inlets, which can match and adapt to cooking utensils of various sizes, thereby achieving better fume gas suction effect and avoiding the disadvantage of collision and overturning caused by high cooking utensils.
