Problems solved by technology

However, the smoke inlet of this side suction range hood is generally provided with a flap, which controls the opening and closing of the smoke inlet through the opening and closing of the flap. There is no shield between the left and right sides of the board and the smoke inlet. The oil fume is easy to escape and spread to both sides during the rising process, and the phenomenon of smoke exhaust and overflow will cause the diffusion of oil fume, which is not conducive to the gathering and extraction of oil fume. , resulting in low range hood efficiency, poor range hood effect and user experience

Embodiment 1

[0048] Such as Figure 1-Figure 10 As shown, the range hood in this embodiment is a side-suction range hood, including a housing 1 provided with an air inlet 100, a flap 2 for flipping and opening and closing the inlet 100, and a device for driving the flap 2 to turn over. A driving device 3, one end of the driving device 3 is hinged in the housing 1 through the first hinge shaft 4, and the other end is connected to the turnover plate 2 through the second hinge shaft 5, and the range hood is provided with a rotating arm 7, the upper end of the rotating arm 7 is hinged with the housing 1 through the third hinge shaft 6, the lower end of the rotating arm 7 is fixedly connected with the top of the turning plate 2, and the third hinge shaft 6 is located at Outside of the straight line where the first hinge shaft 4 and the second hinge shaft 5 are located, the drive device 3 telescopically drives the flap in the direction of connection between the first hinge shaft 4 and the second...

Embodiment 2

[0061] Such as Figures 11 to 15As shown, compared with Embodiment 1, the difference of this embodiment is that the limiting member 304b in this embodiment is installed on the inner side of the mounting plate 102 by screws, and the limiting member 304b is close to the avoidance of the built-in smoke collecting plate 801 The bottom end of the hole 1021 is set, and the limiting member 304b includes two limiting plates 304b1 spaced left and right, and the bottom of the smoke collecting plate 801 is slidably clamped between the two limiting plates 304b1. The two limit plates 304b1 can not only realize the left and right limit of the smoke gathering plate 801, but also reduce the frictional force received by the smoke gathering plate 801 during the overturning process, thereby ensuring the smooth movement of the smoke gathering plate.

[0062] In order to further reduce the frictional force received by the smoke collecting plate 801 during the overturning process and improve the sm...

Embodiment 3

[0065] Such as Figure 16 As shown, compared with Embodiment 1, the difference of this embodiment is that the side wall of the housing 1 in this embodiment is provided with a smoke fin collection guide rail 11, and the smoke collection fin 8 translates in the smoke fin collection guide rail 11 The smoke-collecting fin 8 is slidably connected to the flap 2, so that the flap 2 and the smoke-collecting fin 8 jointly form a smoke-collecting space after it is opened in place. When the flap 2 is in the closed state, the end face of the smoke-collecting fin 8 is far away from or does not touch the flap 2, and can be completely accommodated in the housing 1, so that when the hood is not in use, the smoke-collecting fin and the flap are not in contact. , to avoid the long-term contact of the smoke fins against the flap, causing damage to the flap; There is no gap as much as possible between the smoke plates 8, which is conducive to the gathering and exhausting of oil fume.

Abstract

The invention discloses a range hood hinged to a driving device. The range hood comprises a shell provided with an air inlet, a turning plate for turning and opening the air inlet, and the driving device for driving the turning plate to turn, wherein one end of the driving device is hinged to the shell through a first hinge shaft, and the other end of the driving device is hinged to the turning plate through a second hinge shaft; the range hood is provided with a rotating arm; the upper end of the rotating arm is hinged to the shell through a third hinge shaft, and the lower end of the rotating arm is fixedly connected with the top of the turning plate; smoke gathering fins are arranged at the two ends of the turning plate; and the turning plate drives the smoke gathering fins and the airinlet to define a smoke gathering space. According to the range hood, the smoke gathering fins are arranged, so that oil smoke is effectively prevented from escaping and diffusing towards the two endsof a smoke gathering plate in the rising process, the oil smoke is effectively gathered, the phenomena of smoke overflow and smoke escape are prevented, and the user experience is effectively improved.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood with a drive device hinged. Background technique [0002] The production process of traditional Chinese food culture includes frying, frying, deep-frying, roasting, etc. During the process of making food, a lot of oil fume is produced, and the oil fume not only seriously pollutes the kitchen environment, but also the kitchen operators stay in the oil fume environment for a long time. The harm is relatively large, serious, and even cancer. Therefore, the range hood is widely used in the kitchen. The range hood is an electrical appliance such as the cooking fume that is produced in the home kitchen. [0003] Since the air inlet provided on the shell of the range hood adopts an open design, the oil fume can easily escape from the opening into the kitchen space during the upward movement process. Existing hoods include top suction hoods and side suction hoods....
