Abstract

The utility model relates to a guiding-jetting-type greasy smoke exhaust which is separately provided with an air inlet pipe. A wind inlet is arranged outside a room to introduce fresh air. A blower fan is arranged in the air inlet pipe, and a circular convex ring is arranged in a wind exhausting pipe to form a circular hole. The terminal end of the air inlet pipe in the room is inserted into the wind exhausting pipe and is evenly shrunk to form a circular wind blowing opening and extend into the circular hole of the circular convex ring in the wind exhausting pipe. Greasy smoke and polluted air are inhaled into the wind exhausting pipe without passing through the blower fan and are exhausted to the outdoor atmospheric air by the guide action of air stream. Therefore, the blower fan and the complete exhaust are free from the contamination of oily soil.

Description

Guiding-jetting-type greasy smoke exhaustor

The injection type smoke exhaust ventilator relates to a kind of household electrical appliance, and the utility model is the improvement to existing oil pumper.

The blower fan of existing smoke exhaust ventilator all is mounted in the complete machine body, does not have independent blast pipe, starts fume exhauster motor, and oil smoke is outdoor to the exhaust duct discharge through blower fan and inner all parts from bleeding point, and greasy dirt is full of full machine, quite bothers during cleaning.

The purpose of this utility model is a kind of new smoke exhaust ventilator of design, it is only with a blower fan, this blower fan is installed in the intake stack of setting up separately, rather than be contained in the complete machine body, the blast pipe air port of solely establishing is located at outdoor, the indoor end of blast pipe inserts in the exhaust duct, enters air-flow that ozone quickens through blower fan and utilizes the injection type principle that oil smoke is imported exhaust duct to discharge outdoorly at a high speed from outdoor, and blower fan and complete machine are not infected with by greasy dirt.Do not find identical person through consulting interrelated data as yet with product.

Describe in detail below in conjunction with accompanying drawing and with embodiment:

Fig. 1 is the whole cut-away view of the utility model;

Fig. 2 is the I-I profile among Fig. 1.

See Fig. 1, Fig. 2, the utility model is that the shortcoming and defect part of the oil pumper existence of existing common use is improved innovation, former complete machine body 1 is except that blower fan takes out, miscellaneous part still keeps, various switches 3, illuminating lamp 4, leakage alarm 5 and case 2 bottom smoking suction holes 6 etc. as case 2 and upward installation thereof, the utility model is opened several aspirating holes 6-1 again with case 2 bottoms, with the function of the gas of strengthening evenly pumping; Exhaust duct 10 upwards picks out from case 2 upper ends, extends to outdoorly after the bending, and installing one circular prominent ring 12 forms circular holes in the middle of the circular prominent ring 12 in indoor section pipe; Adjoin with exhaust duct and to establish blast pipe 9, air inlet separately outdoor, indoor section termination inserts in the exhaust duct 10, insert the back parallel direction and also evenly be shrunk to circular air outlet 9-1 to the exhaust outlet extension, circular air outlet 9-1 is inserted in the middle of the circular hole of the prominent ring 12 of circle in the exhaust duct 10, forms an annular space 13 between the two; Blower fan 7 is installed in the blast pipe 9, and is fixing with support 8; Exhaust outlet place at exhaust duct 10 adorns the multipage rain cover 11 that is converted into √ shape, in case rainwater enters in the pipeline.

Start blower fan 7, new wind enters blast pipe 9 from air inlet, form the righteous style and practice pressure condition in the A district and enter the B place, this moment, the C district was negative blast state, the dirty gas of oil smoke enters negative pressure C district from the suction hole 6 of smoking, 6-1, and under the effect of injection type principle, the dirty gas of oil smoke is by the quick air-flow guiding from the A district, discharge rapidly through annular space 13, be discharged in the outside atmosphere along the rainproof window of air outlet.

Blast pipe 9, exhaust duct 10 and circular prominent ring 12 all available galvanized iron sheets process, blast pipe 9 and exhaust duct 10 can be divided into the number joint and peg graft, rainproof window 11 materials generally are to be converted into sheet iron, and the blower motor capacity is 60～80W, and revolution is being advisable more than 1000 rev/mins.

The injection type smoke exhaust ventilator is simple in structure, manufacturing is easy, economize motor, power consumption is few, cost is low, more outstanding superiority is to enter atmosphere fast because of greasy dirt gas, reduce circulation, fan electromotor is not subjected to oil pollution, so blower fan, petticoat pipe etc. can not cleaned for a long time.

This kind exhaust system structure not only is used for the cooking stove exhaust of family, also is applicable to indoor air-changing.

Claims

1, a kind of injection type smoke exhaust ventilator includes blower fan, blast pipe and exhaust duct, it is characterized in that: blower fan 7 is installed in the blast pipe 9; The air inlet of blast pipe 9 is outdoor, and even the contraction formed circular air outlet 9-1 after indoor section termination inserted in the exhaust duct 10; Installing one circular prominent ring 12 is a circular hole in the middle of the circular prominent ring 12 in 10 indoor sections of the exhaust ducts.

2, according to the injection type smoke exhaust ventilator of claim 1, it is characterized in that: air outlet 9-1 stretches in the middle of the prominent ring of circle 12 circular holes of exhaust duct 10, forms annular space 13.
