Abstract
The invention relates to a kitchen ventilator capable of removing oil fume at the top of a kitchen. The kitchen ventilator is characterized in that the middle portion of a fume exhausting pipe arranged above the kitchen ventilator is provided with a throat-shaped pipe with two large-diameter ends and a small-diameter middle portion, a throat pipe at the middle portion of the throat-shaped pipe is communicated with one end of a suction pipe, and the other end of the suction pipe is communicated with a suction hood. An application method for the kitchen ventilator comprises the following steps that: the kitchen ventilator sucks air into the fume exhausting pipe, air flow in the fume exhausting pipe passes through the throat-shaped pipe, and the air flow in the throat pipe at the middle portion of the throat-shaped pipe has an increased flow rate and reduced pressure; air with large pressure in the suction pipe and the suction hood is sucked into the throat pipe, flows out of the fume exhausting pipe along with the air flow in the throat-shaped pipe and enters a flue; and air above the kitchen ventilator and at the top of the kitchen continuously enters the suction pipe from the suction hood so as to supplement pumped air in the suction pipe. The kitchen ventilator has the following beneficial effects: the Venturi effect is adopted to achieve power-free removal of oil fume at the upper portion of the kitchen, simultaneous discharge of the two air flows in the same flue is achieved, and additional arrangement of exhaust holes in the vertical surface of the external wall is avoided.
Description
Technical field
The present invention relates to field of household appliances, particularly relate to a kind of smoke exhaust ventilator.
Background technology
Smoke exhaust ventilator is that family kitchen is the household electrical appliance of the oil smoke that produces in eliminating when cooking.At present, it is several that smoke exhaust ventilator is divided into top suction type, side-suction type and lower-discharging type.When the cooking, particularly, when pouring vegetables into heat oil pot quick-fried, the oil smoke speed of rising rise is very fast, and a part wherein can have little time to be siphoned away by smoke exhaust ventilator, escapes into the top of smoke exhaust ventilator.Because oil smoke lta, this part oil smoke president accumulated time is above kitchen.For various reasons (such as smokejack only has one, or external wall elevation does not allow to occur steam vent etc.) be that exhaust apparatus is not installed on the furred ceiling in kitchen, and smoke exhaust ventilator can only siphon away the air that is positioned at smoke exhaust ventilator below substantially, thus harmful oil smoke of smoke exhaust ventilator top for a long time cannot discharge chamber outside.When this part oil smoke is met cold sinking, but just in time enter in the respiratory tract of people in kitchen harm people's health.
Summary of the invention
The object of the invention is to overcome the defect of prior art, propose a kind of smoke exhaust ventilator that can get rid of top, kitchen oil smoke.
The present invention is achieved in that it comprises smoke exhaust ventilator and smoke exhaust pipe thereof, it is characterized in that smoke exhaust pipe above smoke exhaust ventilator middle part arranges a two ends bore large, the larynx shape pipe that middle part bore is little, the trunnion at this larynx shape pipe middle part is communicated with one end of a suction tube, and the other end of suction tube is communicated with an air-suction cover;
Using method of the present invention is: when the wind wheel of smoke exhaust ventilator rotates, by the air intake smoke exhaust pipe of smoke exhaust ventilator below, the air-flow in smoke exhaust pipe is through larynx shape pipe, and the air-flow velocity in the trunnion at larynx shape pipe middle part increases, and pressure diminishes; The air that in suction tube and air-suction cover, pressure is large is inhaled in trunnion, and flows out together smoke exhaust pipe in company with the air-flow in larynx shape pipe, enters flue; And the air at smoke exhaust ventilator top and top, kitchen constantly enters suction tube from air-suction cover, the air being pumped in supplemental pumping pipe.
The present invention has compared following beneficial effect with the smoke exhaust ventilator of prior art:
When one, smoke exhaust ventilator turns round, can utilize Venturi effect to realize harmful oil smoke on top, unpowered eliminating kitchen, need not set up the exhaust power device at top, kitchen.
Two, can, in same flue, when realizing two strands of air-flows, discharge.Avoid the pore that separately begins to rehearse on external wall elevation.
Accompanying drawing explanation
Below in conjunction with figure and embodiment the present invention is further described.
Fig. 1 is the schematic perspective view of prior art smoke exhaust ventilator.
Fig. 2 is schematic perspective view of the present invention.
Fig. 3 is the lateral plan of Fig. 2.
Fig. 4 is the A-A partial sectional view in Fig. 3.
The specific embodiment
The present invention mainly utilizes the principle of Venturi effect to design: it is large that smoke exhaust pipe 1 middle part above smoke exhaust ventilator arranges a two ends bore, bore little larynx shape in middle part is also Venturi tube to 2(), the one end that is communicated with a suction tube 3 in the middle part trunnion 21 of this larynx shape pipe, the other end of suction tube 3 is communicated with an air-suction cover 4 that is positioned at top, kitchen.In the furred ceiling of air-suction cover 4 operated by rotary motion above smoke exhaust ventilator.
Using method of the present invention is: when the wind wheel of smoke exhaust ventilator rotates, in the air intake smoke exhaust pipe 1 of smoke exhaust ventilator below, the air-flow in smoke exhaust pipe is through larynx shape pipe 2.According to Venturi effect, when pipeline narrows down, the flow velocity of this place's air-flow increases, and pressure diminishes, and namely in trunnion 21, air-flow velocity increases, and pressure diminishes; In suction tube 3 and air-suction cover 4, the large air of pressure is inhaled in trunnion 21, in company with the air-flow in larynx shape pipe 2, flows out together smoke exhaust pipe 1, enters flue (air-flow is from flue is discharged building); And the air at smoke exhaust ventilator top and top, kitchen constantly enters in suction tube 3 from air-suction cover 4, be constantly inhaled in trunnion 21 and flow out smoke exhaust pipe 1 with the air-flow of larynx shape pipe 2.So go round and begin again, the oil smoke at smoke exhaust ventilator top and top, kitchen is discharged.
