Background
With the development of society, the structure of a family house is also changed, rural traditional cooking benches are becoming more and more rare, the structure of the current residential building is that a kitchen is arranged in a suite and is arranged independently, and kitchen fume is discharged through a vertical air duct, so that the range hood gradually becomes one of necessary electrical appliances of the kitchen. The cooking fume is discharged by the range hood for making Chinese catering heavy oil fume, and when a plurality of dishes are cooked in a kitchen, a plurality of cooking ranges can be started at the same time, and for household users, due to the limitation of kitchen area and cooking efficiency, two cooking ranges are usually arranged on a common gas cooker, so that the range hood for household users in China is also usually a double-head range hood and is matched with the cooking ranges of the gas cooker.
Two sides of the double-head range hood are respectively provided with a motor, and the motors drive the turbine to rotate to generate suction force so as to discharge oil smoke. The air quantity is small, the smoking effect is not good, the efficiency is not high and always is a pain point of the double-end range hood, when two motors are started simultaneously to discharge smoke, not only is the air quantity loss caused by the mutual collision of the air inlet series flow of the double-end range hood severe, but also turbulent flow is easily formed when the air outlet series flow of the double-end range hood is mixed with each other, so that the air exhaust kinetic energy is reduced, the smoking and smoke discharging effect is greatly reduced, and the energy consumption ratio of the whole range hood is reduced. Especially when the motor operation power of the two-side machine heads is high and low, one side of the motor operation with high power can form obstruction to exhaust air of one side of the motor operation with low power, and the obstruction has influence on the air inlet side and the air exhaust side of the machine heads, so that when the two-side machine heads of the double-head range hood are used simultaneously, the two-side motor has to be started to the maximum power operation, and the energy consumption is increased.

Preferably, the left and right side walls of the exhaust pipe are provided with waist lines protruding inwards in an arc shape, the positions of the waist line arc tops on the two sides are converged to the narrowest to form a beam air port, the beam air port is positioned above the guide plate, and the limit position of the left and right swing of the guide plate is not more than the connecting line between the rotating shaft of the guide plate and the waist line arc tops on the left and right sides. The beam wind gap is arranged above the guide plate, the beam flow channel is converged at the beam wind gap to enable the airflow to generate higher flow velocity, when the exhaust amount of the left machine head and the right machine head is greatly different, the guide plate swings to one side to enable the widths of the exhaust outlets of the machine heads at two sides to be different, and the machine head airflow at one side with high exhaust amount has higher flow velocity at the beam wind gap to generate jet flow effect to generate suction force for the machine head at one side with low exhaust amount and assist in exhaust.
Preferably, the length of the guide plate is 0.5-0.8 times of the length of the connecting line between the guide plate rotating shaft and the left and right side waist line arc tops. When one side of the machine head is stopped, the guide plate swings to the left limit position or the right limit position, and no matter which position the guide plate swings to, the guide plate can not completely seal the exhaust air of the machine heads at the two sides.
According to the invention, the air channels of the two side heads of the double-head range hood are planned, so that the air inlets at the two sides are not in series flow and do not lose air quantity, the air exhaust channel width can be adjusted by swinging according to the air quantity ratio at the two sides by installing the guide plate at the exhaust pipe, the turbulence at the exhaust side is reduced, the kinetic energy loss is reduced, and the energy efficiency of the range hood is improved.
