Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
In the description of the present invention, it is to be understood that the terms "center," "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 a generic and descriptive sense only and not for purposes of limitation, as the disclosed embodiments of the invention may be oriented in different directions and the directional terms are intended to be illustrative and should not be construed as limiting, such as "upper" and "lower" are not necessarily limited to directions 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 to 3, a range hood includes a fume collecting hood 1 and a fan frame 2 disposed above the fume collecting hood 1.
The smoke collecting cover 1 is provided with a smoke collecting cavity 11 with the bottom sunken upwards, the smoke collecting cover 1 is provided with a main air inlet 12 at the top of the smoke collecting cavity 11, and the main air inlet 12 enables the smoke collecting cavity 11 to be communicated with the fluid inside the fan frame 2. The range hood still includes the cowling panel 3 that corresponds collection smoke chamber 11 and set up, and cowling panel 3 is located the bottom in collection smoke chamber 11, and the rear end of cowling panel 3 extends to the rear end in collection smoke chamber 11, and the periphery and the top of collection smoke chamber 11, cowling panel 3 are formed with ring and inhale air inlet 5.
The range hood also comprises a lifting plate 4 which is matched with the circular suction air inlet 5 in shape and can move up and down relative to the rectifying plate 3, and the lifting plate 4 is arranged in the smoke collection cavity 11. The lifting plate 4 has a first state of moving upward in a direction close to the fan frame 2 to open the ring suction inlet 5, and has a second state of moving to the peripheral position of the rectifying plate 3 to shield the bottom of the smoke collection chamber 11 together with the rectifying plate 3, thereby closing the ring suction inlet 5.
Because the lifting plate 4 is arranged, in the operation process of the range hood, oil stains are mainly attached to the lifting plate 4 and the rectifying plate 3, and therefore daily cleaning is not needed for cleaning the smoke collecting cavity 11, and only the lifting plate 4 and the rectifying plate 3 need to be cleaned.
Referring to fig. 4 to 6, the range hood further includes a lifting device 6 for driving the lifting plate 4 to move. The lifting device 6 is provided with two lifting devices and respectively arranged at the left side and the right side of the fan frame 2, each lifting device 6 comprises a linear driving module and a transmission mechanism, in the embodiment, each linear driving module comprises a driving motor 61, a screw rod 62 driven by the driving motor 61 to rotate, a sliding block 63 capable of linearly moving through the rotation of the screw rod 6 and a lifting rod 64 connected with the sliding block 63, and the lifting rod 64 is longitudinally extended.
A lifting support 65 is arranged between the lifting plate 4 corresponding to the position of the lifting device 6 and the side far away from the rectifying plate 3 and the lifting rod 64, and the lifting support 65 forms a transmission mechanism of the lifting device 6. The number of the elevating brackets 65 corresponds to the elevating device 6. One end of the lifting bracket 65 is connected to the lifting plate 4, and the other end is connected to the lifting rod 64. The lifting rods 64 positioned at the two sides of the fan frame 2 move synchronously to realize the lifting of the lifting plate 4. The connection between the lifting bracket 65 and the lifting plate can be fixed by glue, and the lifting bracket 65 and the lifting rod 64 can be connected by screws.
Referring to fig. 1, when the range hood is in the shutdown state, that is, the lifting plate 4 is in the second state, the lifting plate 4 can be spliced with the fairing 3 at the bottom of the smoke collecting cavity 11, so as to completely shield the smoke collecting cavity 11, that is, the air inlet 5 is sucked by the closing ring, at this time, the bottom surface of the lifting plate 4 is flush with the bottom surface of the fairing 3 and jointly forms the bottom surface of the smoke collecting hood 1, so that the range hood is not affected by the fairing hanger during cleaning, and the lifting plate 4 and the fairing 3 can be cleaned simultaneously.
Referring to fig. 2, when the range hood is in a working state, the lifting plate 4 rises, and the C-shaped ring suction inlet 5 leaks between the lifting plate 4 and the rectifying plate 3, so that a traditional ring suction inlet is formed, and the oil smoke suction effect is ensured. Because the lifting plate 4 can be lifted, the rectifying plate 3 does not need to be detached during cleaning, and the cleaning steps of the range hood are 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), i.e., a fluid (gas, liquid or a mixture of both) can flow along a flow path from the first portion or/and be transported to the second portion, and may be directly communicated between the first portion and the second portion, or indirectly communicated between the first portion and the second portion via at least one third member, which may be a fluid passage such as a pipe, a channel, a duct, a flow guide, a hole, a groove, or a chamber allowing the fluid to flow therethrough, or a combination thereof.
