Problems solved by technology

[0002] Existing range hoods are all installed on the upper end of the range hood. Since the range hood and the range hood are installed separately during use, it is difficult to control the installation height of the range hood. When the installation is low, it will meet and affect the cooking operation. ; If the installation is too high, the oil fume absorption effect will be reduced
At the same time, the existing top-style range hoods are all made in accordance with the European style during use, and their oil fume suction capacity cannot meet the characteristics of the large oil fume in Chinese food, resulting in unsatisfactory oil fume suction effect. Some oil fume still diffuses into the room, the room is easily polluted and the range hood is troublesome to clean, etc.

Embodiment 1

[0016] Embodiment 1: as figure 2 As shown, first use stainless steel to make a Figure 4 The suction mask 2 of the shown shape, the prepared suction mask 2 is placed around the cooking range 1, and the cooking range 1 can be existing common stoves such as fuel oil, gas, induction cooker, resistance furnace, etc., and the lower end of the suction mask 2 is sealed and connected A circular smoke pipe 3, the circular smoke pipe 3 is composed of an inner barrel and an outer barrel, a flue gas pipe 4 is connected to the lower section of the circular smoke pipe 3, and an exhaust fan 5 is connected to the flue gas pipe 4, and the exhaust fan 5 can be Centrifugal fan or axial flow fan, start the present invention when cooking like this, exhaust fan 5 makes circular smoke pipe 3 and flue gas pipe 4 be in negative pressure, and the oil fume that goes out from pot just can be directly absorbed by suction mask 2 and enters circular circuit The smoke pipe 3 is discharged outside the house...

Embodiment 2

[0017] Embodiment 2: as figure 1 As shown, first use stainless steel to make a Figure 4 The suction mask 2 of the shown shape, the prepared suction mask 2 is placed around the cooking range 1, and the cooking range 1 can be existing common stoves such as fuel oil, gas, induction cooker, resistance furnace, etc., and the lower end of the suction mask 2 is sealed and connected A circular smoke pipe 3, the circular smoke pipe 3 is composed of an inner barrel and an outer barrel, and a gap is opened in the middle of the inner barrel to allow the blades of the axial flow fan 7 to rotate. Inside tube 3, as image 3 As shown (that is, in the jacket produced after the inner barrel and the outer barrel are socketed). A smoke pipe 4 is connected to the lower part of the circular smoke pipe 3, and an exhaust fan 5 is connected on the smoke pipe 4. The exhaust fan 5 can be a centrifugal fan or an axial flow fan, so that the axial flow fan 7 and the exhaust fan are turned on when cookin...

Abstract

The invention discloses a manufacturing method of a lower-absorbing range hood and the lower-absorbing range hood. A gas-absorbing face shield connected with a subpressure tube is arranged around a stove to absorb the generated oil-smoke in a short distance. By the gas-absorbing shied which is arranged around the stove and is connected with the subpressure tube, the oil-smoke coming from the frying pan during dishes-frying can be directly absorbed by the invention so as to reduce the chance of oil-smoke diffusion and contamination to the indoor environment; a fan is arranged at the upper end of the stove to generate downward air so as to lead the straight-upward oil-smoke to float to the pan side for being conveniently absorbed by the gas-absorbing face shield, thus further reinforcing the oil-smoke absorption effect; an axial fan is connected with a circular smoke tube, thus further enlarging the subpressure in the circular smoke tube and increasing the oil-smoke absorbing force.

Since the range hood and the range hood are installed separately during use, it is difficult to control the installation height of the range hood. When the installation is low, it will meet and affect the cooking operation. ; If the installation is too high, the oil fume absorption effect will be reduced. At the same time, the existing top-style range hoods are all made in accordance with the European style during use, and their oil fume suction capacity cannot meet the characteristics of the large oil fume in Chinese food, resulting in unsatisfactory oil fume suction effect. Some oily fumes still permeate the room, making it easy to pollute the room and troublesome to clean the ra...
