Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0019] Such as figure 1 with figure 2 As shown, the smoke guide plate lifting mechanism of the range hood in this embodiment includes a mounting frame 1, a driving motor 2, a transmission mechanism 3, a lifting rod 4, a smoke guide plate 5, a U-shaped connecting plate 6 and a guide rail 7 and other components.

[0020] Among them, the driving motor 2 is installed on the back of the front side plate 11 of the mounting frame 1. Such as image 3 with Figure 4 As shown, the transmission mechanism 3 includes a driving gear 31, a driven gear 32, a first rack 33, a second rack 34 and a gear box 35. The driving gear 31 and the driven gear 32 are horizontally arranged side by side and meshed, and the driving gear 31 and the driven gear 32 are arranged in the middle of the front side of the mounting frame 1, and the output shaft of the driving motor 2 passes throug...

Abstract

The invention discloses a smoke guide plate lifting mechanism of a range hood. The mechanism comprises a mounting frame, a driving motor, a transmission mechanism, lifting rods and a smoke guide plate; the driving motor drives the lifting rods and the smoke guide plate to perform a lifting motion through the transmission mechanism; a driving gear and a driven gear of the transmission mechanism are horizontally arranged side by side and engaged with each other; a first rack is vertically arranged on the outer side of the driving gear and engaged with the driving gear; a second rack is vertically arranged on the outer side of the driven gear and engaged with the driven gear; the first rack and the second rack are connected with connecting plates; at least two lifting rods are provided and arranged on the left and right sides of the mounting frame; and the upper ends of the lifting rods are connected to the connecting plates. According to the smoke guide plate lifting mechanism, the transmission mechanism is designed as a double-gear structure; under driving by the driving motor, the first rack and the second rack can move up and down at the same time; the transmission mechanism cannot generate the tooth jump phenomenon and abnormal noise; uniform stress of the lifting rods on two sides is guaranteed; the motion synchronism is excellent; and the smoke guide plate can be kept in stable movement.

Description

Technical field [0001] The invention relates to a range hood, in particular to a smoke guide plate lifting mechanism of the range hood. Background technique [0002] At present, in order to improve the effect of range hoods, people have invented various range hoods with movable smoke guides. When the range hood is working, the smoke guide is driven by the driving mechanism to move up and down or deflect, and then adjust The air inlet angle and air volume of the range hood. For example, "European Range Hood with Automatic Smoke Guide" disclosed in the Chinese Utility Model Patent No. 201620042811.2 (Authorized Announcement No. CN205372692U), the range hood includes a smoke guide plate and a fixed plate, and one side of the fixed plate is provided There are fixed guide rails, the fixed guide rail is equipped with a matching moving guide rail, a transmission rod is arranged next to the fixed guide rail, and the transmission rod abuts against the moving guide rail, and the other sid...
