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 ~ Figure 3 , a range hood, comprising a smoke collection hood 1, a fan cover 2 located above the smoke collection hood 1, an adjustment device 3 and a fan 4 are arranged in the fan cover 2. An air inlet 11 is opened on the fume collecting hood 1 , and the adjusting device 3 corresponds to the position of the air inlet 11 , and is located upstream of the fan 4 on the fume flow path.

[0029] see Figure 3 to Figure 9 , the adjusting device 3 includes a housing 31 , a rotating plate 32 , a first driving mechanism 33 , a moving plate 34 , a second driving mechanism 35 and a spinning blade 36 . Wherein, the casing 31 includes a side wall 311 and a ring wall 312 disposed around the side wall 311 , and the ring wall 312 extends toward the fan 4 for a certain distance. The side wall 311 and the ring wall 312 form a cavity, and...

Abstract

The invention discloses a performance adjusting device of a range hood. The performance adjusting device is characterized by comprising a housing, wherein openings are formed in the bottom surface and the back surface of the housing; a partition plate is arranged in the housing, and a rotation starting blade which can enable a passing air current to rotate is arranged on one side facing the back surface of the housing, of the partition plate, so that a first air current channel is formed in the space located between the partition plate and the back surface, in the housing; a second air current channel is formed in the space located between the partition plate and the front surface, in the housing; a ventilating opening is formed in the partition plate to communicate the first air current channel with the second air current channel; and a rotating plate is arranged under the partition plate, and rotates between the first air current channel and the second air current channel to adjust the proportion of an air current entering the first air current channel to an air current entering the second air current channel. The invention also discloses the range hood applying the performance adjusting device.

Description

technical field [0001] The invention relates to kitchen appliances, in particular to a range hood performance adjustment device and a range hood using the device. 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. [0003] Commonly used range hoods include top-suction and side-suction types. Top-suction range hoods, such as a range hood disclosed in Chinese Patent Application No. The wind cabinet on the upper part of the cover, and the fan with a volute installed in the wind cabinet, through the action of the fan, the gas in the wind cabinet is discharged and a negative pressure is formed at the same time to suck the external oil fume into the cabinet wind cabinet to realize the extraction of oil fume. Purpose: Side-suction range hood, such as the Chinese patent application number 201520377321.3, discloses a side-sucti...
