Abstract
The utility model discloses an internal circulation range hood. The range hood comprises an oil fume exhaust chamber mounted on a wall; an oil fume inlet is arranged on the outer side of or below the oil fume exhaust chamber; a metal net with a pre-set density is mounted on the oil fume inlet; a housing for mounting a fan is arranged above the oil fume exhaust chamber; the fan is positioned at the inner part of the housing; the oil fume exhaust chamber is connected with a wind inlet of the fan through an oil fume chamber; and a wind outlet of the fan is formed at the upper end of the housing. In the utility model, the metal net with the pre-set net is adopted to conduct filtration, and activated carbon is matched with the metal net to absorb oil fume and peculiar smells, so that after filtered by wind, the oil fume is filtered thoroughly; and besides, the exhaust wind has no peculiar smells, so that the oil fume filtration effect is good.
Description
Technical field
The utility model relates to a kind of kitchen appliance, particularly a kind of internal-circulation type smoke exhaust ventilator.
Background technology
Smoke exhaust ventilator is the kitchen essential product, and the quality of its smoke pumping performance directly influences the healthy of the environment in kitchen and user.Existing general smoke exhaust ventilator is that oil smoke is discharged in the atmosphere, the actual secondary pollution that also has oil smoke.Also having a kind of smoke exhaust ventilator is that oil smoke is drained in the specific pond, and this smoke pumping function discharge ring is protected pollution-free gas, reached the standard of environmental protection, but its water tank has taken a part of space, need often change water, brings some inconvenience to the user.
Wire netting has filter effect preferably to oil smoke, because soot gas is bigger than the granularity of natural air, will select suitable grid so filter soot gas, and mesh-density is too big or too little, all is unfavorable for the filtration of soot gas.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple in structure, safety, convenience, need not cleans, internal-circulation type smoke exhaust ventilator that filtering oil smoke is effective, that filter the gas free from extraneous odour of discharging the back.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of internal-circulation type smoke exhaust ventilator, comprise the oil pumping smoke-box that is installed on the wall, the outside of oil pumping smoke-box or below are provided with the oil smoke inlet, the wire netting of predetermined density is installed on the oil smoke inlet, the top of oil pumping smoke-box is provided with the casing that blower fan is installed, blower fan is positioned at the inside of casing, and the oil pumping smoke-box is connected with the air intake vent of blower fan by the oil smoke passage, and the air outlet of blower fan is positioned at the upper end of casing.
Technique scheme also can have following improvement project: the outside of described oil pumping smoke-box or below are an inclined-plane, and the oil smoke inlet is arranged on this inclined-plane; Described inclined-plane is provided with the wire netting of two-layer predetermined density, and the wire netting of two-layer predetermined density is arranged in proper order by front and back; Be provided with the active carbon layer of filterable oil cigarette peculiar smell between the air intake vent of described oil pumping smoke-box and blower fan; The mesh-density of described wire netting is all between the 40-120 order; The mesh-density of described wire netting is between the 40-80 order; The mesh-density of described wire netting is between the 50-60 order; Described blower fan is installed in the casing, and its air outlet is positioned at the upper end of casing.
The beneficial effects of the utility model are: the metal mesh filter that adopts specific density, and cooperate active carbon to adsorb oil smoke and peculiar smell, so, after oil smoke wind filters, filtering oil smoke is thorough, and the wind free from extraneous odour of discharging, effective, the environmental protection of filtering oil smoke, employing density is the metal mesh filter between the 50-60 order, and filter effect is better.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is a plan structure schematic diagram of the present utility model;
Fig. 3 is a left TV structure schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of internal-circulation type smoke exhaust ventilator of present embodiment, comprise the oil pumping smoke-box 1 that is installed on the wall, the outside of oil pumping smoke-box 1 or below are provided with oil smoke inlet 11, the wire netting 12 of predetermined density is installed on the oil smoke inlet 11, and the top of oil pumping smoke-box 1 is provided with the casing 23 that blower fan 2 is installed, and blower fan 2 is positioned at the inside of casing 23, oil pumping smoke-box 1 is connected with the air intake vent 21 of blower fan 2 by oil smoke passage 3, and the air outlet 22 of blower fan 2 is positioned at the upper end of casing 23.
Technique scheme also can have following improvement project: the outside of described oil pumping smoke-box 1 or below are an inclined-plane, and oil smoke inlet 11 is arranged on this inclined-plane, have so just increased the area of oil smoke inlet 11, make the oil pumping better effects if of smoke exhaust ventilator.Described inclined-plane is provided with the wire netting 12 of two-layer predetermined density, the wire netting 12 of two-layer predetermined density is arranged in proper order by front and back, oil smoke wind through double layer of metal net 12 after, its inner soot particles can be fallen by wire netting 12 absorption completely, become clean air, more environmental protection.Be provided with the active carbon layer 4 of filterable oil cigarette peculiar smell between the air intake vent 21 of described oil pumping smoke-box 1 and blower fan 2, can filter out peculiar smell in the oil smoke like this, make air more pure and fresh.Further, as preferred implementation, all between the 40-120 order, further, the mesh-density of wire netting 12 is between the 40-80 order mesh-density of described wire netting 12, and its effect of filtering oil smoke is better.As preferred implementation, the mesh-density of described wire netting 12 is between the 50-60 order, and this is the optimal density value, the 50-60 order, and promptly the mesh number in the per inch is 50 to 60.And wire netting 12 is easy for installation, can easily split out after being stained with oil smoke and clean or change.In order to protect blower fan 2 not infected by outside dust and to make product more attractive in appearance, blower fan 2 is installed in the casing 23, and its air outlet 22 is positioned at the upper end of casing 23, the wind that blows out like this after running into ceiling can to around scatter, avoid wind that the people is directly blown.
Certainly, the utility model is except above-mentioned embodiment, and other equivalent technical solutions also should be within its protection domain.
