Abstract
The invention relates to a range hood capable of removing oil smoke at the top of a kitchen and a using method thereof. The range hood is characterized in that a throat-shaped pipe with large diameters at two ends and a small diameter in the middle is arranged in the middle of a smoke exhaust pipe above the range hood, a venturi in the middle 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 an air suction cover. The using method is that the range hood sucks air into the smoke exhaust pipe, air flow in the smoke exhaust pipe passes the throat-shaped pipe, flow velocity of the air flow in the venturi positioned in the middle of the throat-shaped pipe becomes large, and the pressure becomes small; air with large pressure in the suction pipe and the air suction cover is sucked into the venturi, flows out of the smoke exhaust pipe along with the air flow in the throat-shaped pipe and enters a flue; and air above the range hood and at the top of the kitchen continuously enters the suction pipe through the air suction cover to supplement the pumped air in the suction pipe. The range hood and the using method of the range hood have the advantage that the Venturi effect is utilized to achieve unpowered exhaustion of the oil smoke on the upper portion of the kitchen. Two air flows are exhausted simultaneously in the same flue, and a user does not need to additionally arrange a vent hole on a vertical face of an outer wall.
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 the time produced of the eliminating cooking.At present, smoke exhaust ventilator is divided into several kinds of top suction type, side-suction type and lower-discharging types.When the cooking, particularly when pouring vegetables into the 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 the oil smoke lta, this part oil smoke president accumulated time is above the kitchen.(has only one for various reasons such as smokejack; Perhaps external wall elevation does not allow to occur steam vent or the like) 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 the smoke exhaust ventilator below basically, so harmful oil smoke of smoke exhaust ventilator top can't be discharged outdoor for a long time.When treating this partly oil smoke being met cold sinkings, but just in time get in people's in the kitchen the respiratory tract, endanger people's health.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, propose a kind of smoke exhaust ventilator and the method for using thereof 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 big to it is characterized in that smoke exhaust pipe middle part above smoke exhaust ventilator is provided with a two ends bore; The larynx shape pipe that the middle part bore is little; The trunnion at this larynx shape pipe middle part is communicated with an end of a suction tube, and the other end of suction tube is communicated with an air-suction cover;
Method for using of the present invention is: when the wind wheel of smoke exhaust ventilator rotated, with the air suction smoke exhaust pipe of smoke exhaust ventilator below, the air-flow in the smoke exhaust pipe was through larynx shape pipe, and the air-flow velocity in the trunnion in the middle part of the larynx shape pipe increases, and pressure diminishes; The air that pressure is big in suction tube and the air-suction cover is inhaled in the trunnion, and flows out smoke exhaust pipe together in company with the air-flow in the larynx shape pipe, gets into flue; And the air at smoke exhaust ventilator top and top, kitchen constantly gets into suction tube from air-suction cover, the air of being taken away in the 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 set at top, kitchen.
Two, can in same flue, discharge when realizing two strands of air-flows.Avoid the pore that on external wall elevation, begins to rehearse in addition.
Description of drawings
Below in conjunction with figure and embodiment the present invention is further specified.
Fig. 1 is the schematic perspective view of prior art smoke exhaust ventilator.
Fig. 2 is a 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 among Fig. 3.
The specific embodiment
The present invention mainly utilizes the principle of Venturi effect to design: it is big that smoke exhaust pipe 1 middle part above smoke exhaust ventilator is provided with a two ends bore; Bore little larynx shape in middle part is to 2 (also being Venturi tube); Be communicated with an end of 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.
Method for using of the present invention is: when the wind wheel of smoke exhaust ventilator rotated, in the air suction smoke exhaust pipe 1 with the smoke exhaust ventilator below, the air-flow in the smoke exhaust pipe was through larynx shape pipe 2.According to Venturi effect, when pipeline narrowed down, the flow velocity of this place's air-flow increased, and pressure diminishes, and just air-flow velocity increases in the trunnion 21, and pressure diminishes; The big air of pressure is inhaled in the trunnion 21 in suction tube 3 and the air-suction cover 4, flows out smoke exhaust pipe 1 together in company with the air-flows in the larynx shape pipe 2, gets into flue (air-flow is outside flue is discharged building); And the air at smoke exhaust ventilator top and top, kitchen constantly gets in the suction tubes 3 from air-suction cover 4, constantly is inhaled in the trunnion 21 and flows 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.
Claims (1)
1. the method for using that can get rid of the smoke exhaust ventilator of top, kitchen oil smoke; It comprises smoke exhaust ventilator and smoke exhaust pipe thereof; It is big to it is characterized in that smoke exhaust pipe middle part above smoke exhaust ventilator is provided with a two ends bore; The larynx shape pipe that the middle part bore is little, the trunnion at this larynx shape pipe middle part is communicated with an end of a suction tube, and the other end of suction tube is communicated with an air-suction cover;
The method for using of said apparatus: when the wind wheel of smoke exhaust ventilator rotated, with the air suction smoke exhaust pipe of smoke exhaust ventilator below, the air-flow in the smoke exhaust pipe was through larynx shape pipe, and the air-flow velocity in the trunnion in the middle part of the larynx shape pipe increases, and pressure diminishes; The air that pressure is big in suction tube and the air-suction cover is inhaled in the trunnion, and flows out smoke exhaust pipe together in company with the air-flow in the larynx shape pipe, gets into flue; And the air at smoke exhaust ventilator top and top, kitchen constantly gets into suction tube from air-suction cover, the air of being taken away in the supplemental pumping pipe.
