In the related art, only one main smoke baffle plate is arranged, so that the oil smoke generated during cooking is blocked by the main smoke baffle plate in the rising process, and is sucked into the lower machine body 3 through the lower air inlet below the main smoke baffle plate, but in the sucking process, because both sides of the main smoke baffle plate are in an open structure, the oil smoke can escape outwards from the open structures at both sides, so that the smoke exhaust effect is poor, in the disclosure, the side smoke baffle plates are respectively arranged at both sides of the main smoke baffle plate, so that both sides of the main smoke baffle plate are changed into closed structures, and the oil smoke generated during cooking is blocked by the main smoke baffle plate in the rising process, so that the oil smoke is sucked into the lower machine body 3 through the lower air inlet below the main smoke baffle plate, in the sucking process, because both sides of the main smoke baffle plate are in closed structures, the oil smoke cannot escape outwards from the closed structures at both sides, so that the smoke exhaust effect is improved, and the user experience is further improved.

Further, a first side surface of the first main smoke baffle 331 is disposed at an upper side of the first lower air inlet 31 through a first rotating shaft;

the second side and the third side of the first main smoke baffle 331 are respectively provided with a first side smoke baffle, the surface of the first side smoke baffle is of a foldable structure, and the second side and the third side are two opposite sides of the first main smoke baffle 331; the first main smoke barrier 331 can rotate around the first rotation axis to fold and unfold the first side smoke barrier.

First main cigarette board 331 and two first side cigarette boards have constituted the cigarette structure of holding together on the first air intake, when first main cigarette board 331 rotates to open and when the face that keeps off the cigarette board with two first sides expandes with the drive, this structure can be gathered together the inside oil smoke of fuselage 3 down that gets into from first air intake 31 in first main cigarette board 331 and two first side cigarette boards enclose gather together the structure in, the oil smoke can not outwards loss, thereby the suction effect of smoke ventilator has been promoted.

Because the both sides at first main cigarette board 331 have set up first side cigarette board respectively, thereby make the both sides of first main cigarette board 331 become enclosed construction, in-process when the oil smoke is ascending, can be blocked by first main cigarette board 331, thereby it inhales down fuselage 3 inside to inhale through first air intake 31 under first main cigarette board 331, at the inspiratory in-process, because the both sides that first main cigarette board 331 kept off are enclosed construction, thereby the outside loss of enclosed construction of this both sides can not be followed to the oil smoke, smoke exhaust effect has been promoted, and further user experience has been promoted.

Further, the first side surface of the second main smoke baffle 332 is disposed at the upper side of the second lower air inlet 32 through the second rotating shaft,

a second side smoke baffle plate is arranged on the second side surface and the third side surface of the second main smoke baffle plate 332 respectively, the plate surface of the second side smoke baffle plate is of a foldable structure, and the second side surface and the third side surface are two opposite side surfaces in the second main smoke baffle plate 332; the second main smoke barrier 332 can rotate around the second rotation axis to fold and unfold the second side smoke barrier.

The second keeps off the cigarette board 332 and two second sides and keeps off the cigarette board and constitute and hold together the cigarette structure on the second air intake, keep off the cigarette board 332 when the second is main to be opened in order to drive and two second sides keep off the face of cigarette board and expand, this structure can be gathered together the inside oil smoke of fuselage 3 down that gets into from second lower air intake 32 in the second main keeps off the structure of gathering that cigarette board 332 and two second sides keep off the cigarette board and enclose, the oil smoke can not outwards loss, thereby the suction effect of smoke ventilator has been promoted.

Because the both sides at the second main cigarette board 332 of keeping off have set up the second side respectively and have kept off the cigarette board, thereby make the second main both sides of keeping off the cigarette board 332 become enclosed construction, in-process when the oil smoke is ascending, can be kept off the cigarette board 332 by the second owner, thereby it inhales down fuselage 3 inside to pass through second main second lower air intake 32 that keeps off under the cigarette board 332, at the inspiratory in-process, because the second owner keeps off the both sides of cigarette board 332 and is enclosed construction, thereby the outside loss of enclosed construction of this both sides can not be followed to the oil smoke, smoke exhaust effect has been promoted, and further user experience has been promoted.

Further, when using cooking utensils such as gas-cooker to cook, often can produce the oil smoke, the user generally can use smoke ventilator to inhale the row to the oil smoke that produces, but the smoke ventilator that present lid was inhaled only has an air intake and a baffle, when opening the smoke ventilator, need open this baffle, let the air intake expose, in order to reach the purpose of inhaling the row's oil smoke through the air intake, but the user cooks if only using the gas range head on the left side when cooking, the gas range head on the right is not used, at this moment, do not have the air intake that the gas range head on the right corresponds of necessarily opening. And set up two independent air intakes in this disclosure to can be according to actual need nimble open the main cigarette board that keeps off in the required lower air intake, effectively promoted user experience, and because the area that the main cigarette board kept off this moment is less than correlation technique, consequently, can effectively save the electric quantity.

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: the smoke ventilator with many air intakes in this disclosure includes: the host comprises a host shell, a fan arranged in the host shell and an electric control box electrically connected with the fan; the upper machine body is arranged below the main machine, and the bottom of the machine body of the upper machine body is provided with an upper air inlet; the lower machine body is arranged below the upper machine body, the upper machine body and the lower machine body are in an inverted L-shaped structure, and the interior of the lower machine body is communicated with the interior of the upper machine body; the lower machine body is provided with a first lower air inlet and a second lower air inlet, and one sides of the first lower air inlet and the second lower air inlet, which are far away from the lower machine body, are provided with a rotatable main smoke baffle and side smoke baffles positioned at two sides of the main smoke baffle; the main smoke baffle plate can drive the plate surfaces of the side smoke baffles to fold and unfold when rotating; the first air inlet and the second air inlet are respectively positioned on the left side and the right side of the lower machine body. Owing to set up two independent air intakes, set up main cigarette board and side cigarette board of keeping off on each air intake respectively, thereby can select the air intake of opening which one side according to actual need, because single main cigarette board of keeping off compares in the whole cigarette board volume that keeps off in the correlation technique diminishes, thereby effectively saved the power consumption, and at the in-process of suction and exhaust oil smoke, can effectively avoid the outside loss of oil smoke, promoted smoke exhaust effect, and further promoted user experience.

The present disclosure also provides another range hood, in the range hood, both the first lower air inlet 31 and the second lower inlet may not need to be provided with a main smoke baffle and a side smoke baffle, at this time, a schematic diagram of the upper air inlet in the upper body 2 is shown in fig. 5, a schematic diagram of the first lower air inlet 31 and the second lower air inlet 32 in the lower body 3 is shown in fig. 6 or fig. 7, the first lower air inlet 31 or the second lower air inlet 32 is used as the main air inlet, and the air inlet area is the largest; an upper air inlet in the middle of the upper machine body 2 is used as an auxiliary air inlet to assist in absorbing oil smoke, and the air inlet area is smaller than that of the lower air inlet; the area of the upper air inlet arranged at the two sides in the upper machine body 2 is minimum, and the main function is to form an air curtain to assist in sucking and exhausting oil smoke; when a user cooks, especially fries quickly, a large amount of oil smoke can be generated, and a mode of sucking and exhausting oil smoke step by step can be adopted: firstly, when a large amount of oil smoke rises, most of the oil smoke is sucked and exhausted through the lower air inlet, and as the first lower air inlet 31 and/or the upper edge of the second lower air inlet 32 is not provided with a baffle, a part of the oil smoke continues to rise, and at this time, the upper air inlet in the middle position in the upper machine body 2 sucks and exhausts the part of the oil smoke; when the generated oil smoke is too large, part of the oil smoke cannot be sucked and exhausted by the upper air inlets in the middle position of the upper machine body 2 due to reasons such as interference, and at this time, the part of the oil smoke can be completely sucked and exhausted due to the fact that the upper air inlets arranged at the two sides of the upper machine body 2 form the air curtain; that is, during ordinary cooking, the oil smoke generated at this time is relatively less, and the oil smoke is exhausted by the first lower air inlet 31 and/or the second lower air inlet 32. The oil smoke is sucked and exhausted by the three-step method, so that the air suction efficiency of the range hood can be improved, and the oil smoke is prevented from leaking to a kitchen space. The range hood can also have a function of removing kitchen odor, and when the range hood is used for removing the kitchen odor, the range hood is mainly used for sucking and exhausting through the first lower air inlet 31 and/or the second lower air inlet 32 and the upper air inlet in the middle of the machine body. In order to achieve a reliable suction and exhaust effect, the vertical distance between the upper edges of the first lower air inlet 31 and the second lower air inlet 32 and the bottom of the upper machine body 2 may be 20-30 cm. In this embodiment, the areas and structures of the lower air inlets and the upper air inlets may be modified and adjusted according to actual requirements and manufacturing equipment.

Fig. 8 is a front view illustrating the lower body according to an exemplary embodiment, and as shown in fig. 8, in order to improve the suction and exhaust effects of the range hood, the first main smoke barrier 331 has a coverage area less than or equal to the area of the first lower intake vent 31.

The coverage area of the first main smoke baffle 331 is smaller than or equal to the area of the first lower air inlet 31, so that when a small amount of oil smoke exists, the first main smoke baffle 331 does not need to be opened, at the moment, the first main smoke baffle 331 is closed, the oil smoke can be sucked into the lower machine body 3 through the exposed first lower air inlet 31, and therefore when the small amount of oil smoke exists, the first main smoke baffle 331 does not need to be opened and the exhaust can be effectively conducted.

In one implementation manner, the length of the second side or the third side of the first main smoke baffle 331 may be set to be less than or equal to the length of the corresponding edge of the first lower air inlet 31.

In order to more clearly illustrate the solution of the present disclosure, the length of the second side or the third side of the first main smoke barrier 331 is referred to as the width of the first main smoke barrier 331, and the lengths of the other two sides are referred to as the length of the first main smoke barrier 331.

The width through setting up first main cigarette board 331 is less than the width of air intake down to when first main cigarette board 331 closed, first air intake 31 is not sheltered from completely, and at this moment, the oil smoke just can be followed the first air intake 31 that exposes and inhaled down inside fuselage 3, thereby when having the small amount oil smoke, need not to open first main cigarette board 331 and also can effectual suction row.

In one implementation manner, in order to improve the blocking effect of the first main smoke barrier 331 on the oil smoke, the rotation angle of the first main smoke barrier 331 is less than or equal to 45 degrees. That is, the included angle between the width direction of the first main smoke baffle 331 and the gravity direction is less than or equal to 45 degrees.

The coverage area of the second main smoke baffle 332 is smaller than or equal to the area of the second lower air inlet 32.

The area of the second lower air inlet 32 is smaller than or equal to the coverage area of the second main smoke baffle 332, so that the second main smoke baffle 332 is not required to be opened when a small amount of oil smoke exists, the second main smoke baffle 332 is closed at the moment, the oil smoke can be sucked into the lower machine body 3 through the exposed second lower air inlet 32, and the second main smoke baffle 332 is not required to be opened when the small amount of oil smoke exists.

In one implementation, the length of the second side or the third side of the second main smoke baffle 332 may be set to be less than or equal to the length of the corresponding edge of the second lower air inlet 32.
