Range hood with secondary air-sucking function

Abstract

The invention discloses a range hood with a secondary air-sucking function. The range hood comprises a range hood body and a panel arranged on the range hood body, wherein an air-sucking turbine is arranged in the range hood body; an air inlet of the air-sucking turbine is connected with a smoke inlet of the panel, and an air outlet of the air-sucking turbine is connected with a smoke discharging pipe; an oil filtering screen is covered on the smoke inlet; the range hood with the secondary air-sucking function is characterized in that a secondary air-sucking device is arranged between the air inlet of the air-sucking turbine and the smoke inlet of the panel; the secondary air-sucking device is capable of extracting air from the outside of the range hood body and supplying the air into the air-sucking turbine. The range hood with the secondary air-sucking function has the beneficial effects that the total air-sucking amount of the range hood is equal to the sum of the air-sucking amount of the turbine and the air-sucking amount of the secondary air inlet structure due to the special secondary air-sucking structure, so that the range hood has relative high air-sucking amount, and the working efficiency of the range hood is improved; the range hood with relatively high air-sucking amount can accelerate the suction and the emission of the kitchen lampblack, so that the freshness of the kitchen air environment is ensured.

Description

technical field [0001] The invention relates to a kitchen appliance, in particular to a range hood with a secondary air intake function. Background technique [0002] The general structure of the exhaust device used by the traditional range hood is a turbine-type housing, a motor and a wind wheel installed in the housing, and the motor drives the wind wheel independently to suck the oil fume produced by the left and right burners. Because, the ventilation device of this traditional structure is placed in a parallel structure, and only the front side of the housing has air intake, and there is no or very little air intake space at the back. In this way, if the front of the housing is blown in from one side, it is easy to cause a great loss of kinetic energy, and the air volume is small, so it is difficult to ensure that the oil fumes generated by the left and right burners are sucked clean. At the same time, the suction turbine technology of the existing range hood is quite ...

Problems solved by technology

Therefore, the only way to increase the turbine speed is to increase its suction volume. However, with the increase of the turbine speed, the operating noise of the range hood will increase accordingly. Therefore, the number of revolutions of the turbine is also set within a certain limit value. , otherwise, the excessive working noise of the range hood is bound to affect its quality of use, so it is necessary to further improve the structure of the existing range hood
