Problems solved by technology

Under normal circumstances, the shrapnel or buckle of the rectification plate need to be able to withstand its own weight plus some oil pollution and a certain impact. When designing, the user has to push and pull with a large force (the shrapnel and buckle are loose and easy to vibrate and fall off). When the user pushes and pulls the rectifier When the strength of the plate is not enough to overcome the elasticity of the shrapnel, the user may not be able to remove or close the rectifying plate, resulting in the user being unable to clean and close normally, and the sound is unpleasant

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] see Figure 1 to Figure 7 , a range hood, comprising a fume collection hood 1, a box 2 arranged above the fume collection hood 1, and a strip-shaped oil cup 3 arranged below the rear side of the fume collection hood 1. An upwardly concave smoke collection chamber 11 is formed in the smoke collection hood 1, and an air inlet 12 is opened on the smoke collection hood 1 to connect the smoke collection chamber 11 with the inside of the box body 2, so that oil fume can enter the box body 2 through the air inlet 12 and discharged through the fan system (not shown) in the box 2. The air inlet 12 is provided with a filter screen 4 .

[0029] A rectifying plate 5 is arranged in the smoke collecting chamber 11 below the air inlet 12 . The rear edge of the rectifying plate 5 is located above the oil cup 3 , and the edge of the rectifying plate ...

Abstract

The invention discloses an extractor hood which comprises a fume collecting hood. An air inlet is formed in the fume collecting hood. A fume collecting cavity concaved upwards is formed in the fume collecting hood. The commutated plate is arranged at the position, located below the air inlet, in the fume collecting cavity. The front portion of the commutated plate is clamped with the fume collecting hood through a clamped connection structure. The rear portion of the commutated plate is hinged to the fume collecting hood. The clamped connection structure comprises clamping claws arranged on the two sides of the front portion of the upper surface of the commutated plate. The extractor hood is characterized in that the clamped connection structure further comprises buckles, and the buckles can be in clamped connection with the clamping claws, apply suction force and can apply repellent force to the clamping claws to be separated from each other. The invention further discloses a controlmethod of the extractor hood.

Description

technical field [0001] The invention relates to kitchen equipment, in particular to a range hood having a rectifying plate and a method for controlling the movement of the rectifying plate of the range hood. Background technique [0002] The range hood has become one of the indispensable kitchen appliances in modern families, and it is used to exhaust the oil fume produced during the cooking process of the stove. Generally, range hoods include top-suction and side-suction types, and top-suction range hoods are more and more widely used due to their neatness, lightness, and small footprint. [0003] The top-suction range hood usually includes a fume collecting hood, a fan casing positioned on the fume collecting hood, and a centrifugal fan is installed in the fan casing. For example, a range hood disclosed in Chinese patent application No. 201310111398.1 includes a fan for generating air flow, an inner panel on the inner surface of the exhaust hood, and a filter detachably i...
