Opening and closing plate structure of range hood

Abstract

The invention discloses an opening and closing plate structure of a range hood. A first opening and closing plate is driven by a corresponding lifting assembly to do lifting motion through rotation work of a first transmission assembly, and meanwhile, the first transmission assembly drives a second transmission assembly to do synchronous motion, and a second opening and closing plate is driven by the corresponding lifting assembly to do lifting motion through rotation work of the second transmission assembly, and then the first opening and closing plate and the second opening and closing plate are driven to synchronously move so as to adjust the opening and closing state of a first air inlet or a second air inlet. According to the opening and closing plate structure of the range hood provided by the invention, the structure is simple, the smoke gathering area of the range hood can be effectively enlarged, the smoke discharging effect is further improved, and meanwhile the production cost of a product can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an opening and closing plate structure of a range hood. Background technique [0002] At present, range hoods are mainly divided into two categories according to their appearance: top suction and side suction. Among them, the top smoking machine has a higher hanging height and has a larger operating space. However, due to the large distance between the air inlet of the hood and the cooker, oily fumes are prone to overflow at the moment of stir-frying. Existing top-of-the-line smoking machines mostly use deep chambers, smoke gathering plates, air curtains, butterfly wing plates, etc. to improve smoke control. Ability to reduce oil fume spillage. [0003] In related technologies, most of the promotional selling points on the market are range hoods with opening and closing panels. Generally, a single geared motor or electric push rod drives the opening and closing panel...

AI Technical Summary

Problems solved by technology

However, for range hoods with two or more air inlets, the hood can only close or open the air inlets at the same time, and cannot move independently

For range hoods with two air inlets, the air inlets cannot match the size of the oil fume below, and the opening and closing positions of the opening and closing plates cannot be adjusted independently, so intelligent partition smoke control cannot be realized

At present, there are products that use one air inlet corresponding to one opening and closing plate and one set of motion mechanism on the model that promotes partitioned smoke control. Although this can realize the opening and closing of the opening and closing plate independently, there are two sets of motion mechanisms and two drive motors. Increase the cost, and the space occupied by the motion mechanism is relatively large
