In a specific embodiment, the width of the lower smoking body 2 is 450mm.

In this embodiment, specifically, the width of the lower smoking body 2 is 450mm from left to right, and this width is adapted to the width of a single cooking range, so that the area formed by the recess of the front side wall of the lower smoking body 2 is adapted to the active area of the frying pan.

In another aspect, another embodiment of the present utility model provides an oil smoke absorbing system for efficiently absorbing oil smoke, comprising: the two efficient lampblack-absorbing lampblack absorbers are arranged side by side.

In this embodiment, in order to match the double-burner range 24 in a common household, two extractor hoods for efficiently extracting the oil smoke are arranged side by side.

Specifically, the height of the lower smoking body 2 is 410mm, the width of the upper smoking body 1 is 400mm, the sum of the heights of the upper smoking body 1 and the cover 16 is 400mm, and the front-rear width of the upper smoking body 1 is 500mm.

Specifically, the front side wall of the upper smoking body 1 is inclined for guiding the smoke passing through the first smoke inlet 3 to the inlet of the first blower mechanism 5.

As shown in fig. 11, in particular, in the efficient fume exhaust system, the rotation directions of the impellers of the two first air blowing mechanisms 5 are opposite, so that the fume exhaust pipes 7 of the two first air blowing mechanisms 5 are symmetrical and are close to each other; the impellers of the two second air blowing mechanisms 6 rotate in opposite directions, so that the smoke exhaust pipes 7 of the two second air blowing mechanisms 6 are symmetrical and close to each other. Four smoke exhaust pipes 7 and the exhaust pipe 1701 which are close to each other penetrate through the same hole of the kitchen wall body to exhaust the smoke outside.

As shown in fig. 14, through multiple experiments, the applicant found that two 550W blowers are placed in a cuboid with 900mm x 110mm x 410mm in the lower half part of the system, and the two blowers are separated and sealed from each other to form two independent working spaces, so that two identical lower smoking bodies are formed, the distance from the outer plate surface of each lower smoking body to the air inlet of the blower is 42mm, and two side edges of the outer plate surface of each lower smoking body are raised forward to form an eight-shaped bulge 130mm and approach to the limit distance. If the distance from the outer plate surface to the air inlet of the air blower is too short, the air blower does not work normally. Because the lower half part of the system is thinner, the reserved width of the cooking bench is wider, conditions are created for the convenient operation of the frying pan, the bulge part not only enlarges the air inlet space of the blower, but also directly prolongs the suction distance of the blower, the two smoke inlet of the left lower smoke suction main body are 350mm long and 7mm wide, and the smoke inlet of the right lower smoke suction main body is the same in size. In this case, the blower approaches the operating state in the original unrestricted condition. Even if the exhaust pipe of the blower bends at approximately 90 degrees, the blower is close to the normal unlimited operating state.

As shown in fig. 15, the lower smoking body outer panel (front side wall) includes a flat plate 30 in the middle (its left and right width is 100 mm) and raised plates 31 on both sides of the flat plate (raised plates extend forward relative to the flat plate, its left and right width is 200, and its front and rear width is 90 mm), and the second smoke inlet 4 extends forward by a distance of 40mm.

As shown in fig. 15, the front-back width of the top of the lower smoking body is 500mm, the front-back width of the bottom of the lower smoking body is 110mm to 120mm wide, the front-back width of the bottom of the lower smoking body is narrower, a margin is reserved for placing a frying pan on a cooking bench, meanwhile, the front-back width of the top 6 of the lower smoking body is larger than the diameter of the frying pan, and the first smoke inlet 3 of the upper smoking body is positioned outside the second smoke inlet 4 of the lower smoking body, so that the smoking range of the door-shaped frame structure formed by the three smoke inlets completely covers the frying pan.

Through experiments, the suction distance (the distance extending outwards from the port of the smoke inlet 4) between the two smoke inlets of the lower left smoking main body is about 100mm, and the right side is the same as the left side, and obvious suction is also arranged at the position about 100mm from the smoke inlet. And the upper and lower middle parts of each smoke inlet are uniformly air-inlet, and the suction force is stronger when the smoke inlet is closer to the air inlet.

The suction distance of the lower half blower is as follows: 42mm (distance between air inlet of blower and outer plate surface) +130mm (height of bulge of outer plate surface) +100mm (suction distance of outward extension of strip-shaped smoke inlet 4) =272 mm, namely the distance of the air blower at 272mm after transformation has obvious air inlet. The smoke inlet 4 is obliquely arranged, the upper end of the smoke inlet 4 extends forwards to the position of about 500mm relative to the inner wall surface of the cooking bench, the width of the dirt receiving box 8 is 80mm, and as shown in fig. 1 to 5, the size of a frying pan can be covered, and the purpose of cleanly sucking oil smoke is achieved.

According to the principle of air suction and air exhaust of the air blower, the applicant selects a 550W air blower to manufacture a lower smoking main body and also manufactures an upper smoking main body.

At the top of this system, applicant selected 550W blower to make a stepped cuboid box (upper smoking body), and blower exhaust tube does not need to bend and exhaust. A cuboid, which is closely attached to the air inlet of the blower, has a length of 390mm, a width of 250mm and a height of 70mm, and is shown as a space of 101 part in fig. 12; the middle cuboid is 390mm long, 140mm wide and 160mm high, as in section 102 of fig. 12; in FIG. 12, the smoke inlet 3 is 390mm long, 8mm wide and 40mm high. Suction distance of upper smoking body: 70mm (height of cuboid close to air inlet of blower) +160mm (height of middle cuboid) +40mm (height of upper smoking main body smoke inlet 3) +160mm (suction distance of smoke inlet 3 extending outwards) =430 mm, that is, there is obvious suction from top air inlet of blower to about 430 mm. And suction is uniform in the strip holes of 390mm x 8mm of the smoke inlet.

The system works independently, the left and right smoke exhaust ventilator respectively, the upper smoke absorbing main body at the top of the left side and the lower smoke absorbing main body at the lower part of the left side correspond to a kitchen range, the upper smoke absorbing main body at the top of the right side and the lower smoke absorbing main body at the lower part of the right side correspond to a kitchen range, and the kitchen range on the left side can be used independently, the kitchen range on the right side can be used independently, and the kitchen ranges on the two sides can be used simultaneously.

The air discharge amount of the blower (550W) was 18 cubic meters per minute, which is also the air suction amount of the blower, and was converted into the amount of smoke, which data was obtained from the instruction of the 550W blower.

The power of the blower and the motor determines the suction distance and the suction volume. The three-phase motor can be used for driving a larger blower, so that the ceiling type range hood can be manufactured, and the ceiling type range hood is suitable for large-scale catering places such as schools and hotels. According to the requirement, the volume of the limited space can be changed, the air inlet distance and the air inlet mode can be changed, so that the system can better serve us.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
