Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present invention and to simplify the description, but are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and that the directional terms are used for purposes of illustration and are not to be construed as limiting, for example, because the disclosed embodiments of the present invention may be oriented in different directions, "lower" is not necessarily limited to a direction opposite to or coincident with the direction of gravity. Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1, 4 and 7, a side-draft range hood includes a housing 1 and a fan frame 5 disposed above the housing 1, and a fan system 6 is disposed in the housing 1 and the fan frame 5. An opening 2 is formed at the front side of the housing 1, and an air inlet 21 in fluid communication with the inside of the housing 1 is formed at the opening 2.

The opening of the range hood is provided with a smoke baffle component 3, and the smoke baffle component 3 comprises a first smoke baffle 31 and a second smoke baffle 32 which are overlapped up and down. The first smoke barrier 31 and the second smoke barrier 32 can be in a first state of closing the air inlet 21, and a second state of turning the first smoke barrier 31 forward while the second smoke barrier 32 moves toward the front side to expose the air inlet 21.

The front lower part of the second cigarette blocking plate body 321 is provided with a panel 4. The upper portion of the front side of the second smoke baffle body 321 is formed with an accommodating area 3211 for accommodating the first smoke baffle 31, and when the first smoke baffle 31 and the second smoke baffle 32 are in the first state, the front side surface of the first smoke baffle 31 is flush with the front side surface of the panel 4.

The air inlet 21 is located at the lower part of the opening 2, the upper end of the first smoke baffle 31 is rotatably connected with the upper end of the opening 2, the upper end of the second smoke baffle 32 is rotatably connected with the first smoke baffle 31, preferably the middle part of the first smoke baffle 31, and the lower part of the second smoke baffle 32 is slidably connected with the upper part of the air inlet 21. The rotational connection in this embodiment is a connection manner in which the rotational axis extends in the left-right direction.

Referring to fig. 2 to 9, the second cigarette retaining plate 32 includes a second cigarette retaining plate body 321 and second cigarette retaining plate side plates 322 respectively disposed on the left and right sides of the second cigarette retaining plate body 321, and the second cigarette retaining plate side plates 322 extend toward the inner side of the housing 1. When the first smoke baffle 31 and the second smoke baffle 32 are in the second state, each second smoke baffle side plate 322 forms a closed part of the second smoke baffle body 321, the first smoke baffle 31 and the area between the corresponding sides of the shell 1, so as to prevent the oil smoke in the shell from leaking.

A sliding groove 3221 extending in the length direction is formed on the second smoke baffle side plate 322, and a protrusion 11 slidably engaged with the sliding groove 3221 is formed on the inner side of the corresponding side portion of the housing 1.

A moving mechanism for driving the smoke barrier assembly 3, such as a four-bar mechanism, may be provided in the housing 1 to drive the second smoke barrier 32 to move, so as to drive the first smoke barrier 31 to open and close.

In this embodiment, the air inlet 21 is located at the lowest side of the opening 2, so as to ensure good oil smoke suction effect. Meanwhile, the double-baffle structure solves the problems that the conventional smoke baffle is longer after the air inlet is arranged under the cooker and interferes with the cooker in the opening process. The double smoke baffles can also play a role in expanding the space, so that more sinks of the fan system can be realized, the height of the fan frame 5 is reduced, the air inlet resistance of the fan system 6 is reduced, and the cost is reduced.

The term "fluid communication" as used herein refers to a spatial relationship between two components or portions (hereinafter collectively referred to as a first portion and a second portion, respectively), i.e., a fluid (gas, liquid or a mixture of both) can flow along a flow path from the first portion and/or be transported to the second portion, and may be a direct communication between the first portion and the second portion, or an indirect communication between the first portion and the second portion via at least one third element, such as a fluid channel, e.g., a pipe, a channel, a duct, a flow guide, a hole, a groove, or a chamber that allows a fluid to flow through, or a combination thereof.
