Problems solved by technology

However, in order not to affect the effect of suction and exhaust, and not to increase the burden on the suction and exhaust fans, the air supply power is usually small, which leads to the gradual weakening of the wind force during the descent; The impact is obvious, such as the change of air flow caused by the stir-frying action of the cook, etc. A little disturbance will disperse the air curtain and affect the shielding effect of the air curtain. more floating fumes

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Such as Figure 1 to Figure 7 As shown, the range hood with suction device includes:

[0030] The main body 2 of the range hood includes a box body 21 and a cover plate 22 installed on the box body 21. The cover plate 22 is provided with two groups of air supply ports 23, and the two groups of air supply ports are arranged symmetrically with the center line of the cover plate as the center, and, There are two air outlets 23 in each group, and they are arranged on the same circumferential line at intervals.

[0031] The air blowing device 1 , the driving device 3 and the detecting element 4 are all installed in the cavity between the box body 1 and the cover plate 2 .

[0032] Among them, there are two groups of air supply devices 1, which are arranged symmetrically with respect to the center line of the range hood main body 2. Each gr...

Abstract

The invention relates to an extractor hood with an absorption assisting device and a method for pumping and absorbing oil fume. The extractor hood comprises an extractor hood main body and air supply devices arranged on the extractor hood main body, and is characterized by further comprising driving devices, detectors used for detecting the position of cookware, and a control device; each air supply device comprises a centrifugal fan, the exhaust port of the centrifugal fan is connected with an air duct, the air duct is provided with at least one air outlet, and the air outlet is downward or obliquely downward; the driving devices are connected with the air supply devices in a driving way and used for changing the direction of airflow output by the air supply devices; and the driving devices and the detectors are both connected with the control device. The air supply airflow of the extractor hood with an absorption assisting device directly blows into the cookware, and can propel the oil fume to gather to the exhaust opening of the extractor hood at the beginning of generation of the oil fume, thus thoroughly avoiding overflow of the oil fume in rising.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood with a suction device and a method for sucking the range hood. Background technique [0002] In order to solve the problem of oily fumes spreading to the surroundings during cooking, people have developed a range hood with an air curtain. By installing an air supply device on the range hood, the air is sent to the periphery of the cooktop, and an air curtain is formed around the cooktop. Prevent the oil fume from spreading around. However, in order not to affect the effect of suction and exhaust, and not to increase the burden on the suction and exhaust fans, the air supply power is usually small, which leads to the gradual weakening of the wind force during the descent; The impact is obvious, such as the change of air flow caused by the stir-frying action of the cook, etc. A little disturbance will disperse the air curtain and affect the shielding effect of the air curtain. More fl...
