Abstract

The invention relates to a range hood, comprising a case and a smoke collecting cover connected below the case, wherein a centrifugal fan is arranged in the case, and an air inlet communicating with an inner cavity of the case is arranged on the smoke collecting cover. The range hood is characterized in that the centrifugal fan is a double-suction centrifugal fan; the smoke collecting cover comprises a first cavity and a second cavity which are independent of each other, the air inlet communicates with the first cavity, and the first cavity communicates with a front air inlet of the centrifugal fan; and the second cavity extends downwards and is provided with an inclined plane which is inclined forwards from bottom to top, left side axial flow fans and right axial flow fan are arranged at intervals on the inclined plane, a baffle plate is arranged in the second cavity to divide the second cavity into a left passage corresponding to the left axial flow fan and a right passage corresponding to the right axial flow fan, and the left passage and a second airflow passage are both communicated with a rear air inlet of the centrifugal fan. According to the invention, the suction and discharge effect of the range hood can be significantly improved.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with an adjustable negative pressure area. Background technique [0002] The range hood generally includes a casing, and a centrifugal fan is arranged in the casing, and the oil fume is sucked by the centrifugal fan. However, in order to facilitate the user to cook, the range hood is usually installed at a certain height, so that, under the disturbance of the external wind force, the oil fume will escape to the surroundings, causing smoke to escape. [0003] CN201220459447.1 discloses an "Axial Flow Range Hood with Horizontal Double Suction Port Installation Structure", which includes two curved pipe axial flow fume fans arranged side by side, a frame, an external exhaust pipe, and a curved pipe axial flow fume fan It includes: a curved pipe, a fan motor arranged in the curved pipe and a fan body installed on the shaft of the fan motor, and the motor is fixed in the curve...
