Abstract
A kind of range hood without wind wheel.Comprise exhaust fume collecting hood and wind cabinet, its wind cabinet comprises oil smoke passage, oil smoke passage one end connected set petticoat pipe, one end is by pipeline communication common flue in addition, in oil smoke passage, be provided with the guide ring for generation of high pressure draught, guide ring inner hollow, which is provided with the venthole that some directions are consistent or goes out compression ring, and end is provided with air inlet; Oil smoke passage is provided with gas outlet, and one end, gas outlet and air inlet are by screw thread or clamp connection, and other one end, gas outlet is communicated with the high pressure draught generating means of oil smoke passage outside.In wind cabinet of the present utility model, without the structure of wind wheel type, make the operating noise of range hood extremely low, guide ring produces high pressure draught and produces negative pressure in oil smoke channel interior, indoor oil smoke is discharged to smoothly outdoor, and suction oil smoke is effective.The detachable design of guide ring, can take off separately cleaning.Because of in flue without wind wheel and motor, make range hood inside more easily clean or exempt from clean.
Description
Technical field
The utility model relates to a kind of range hood without wind wheel.
Background technology
Existing lampblack-pumped kind is a lot.As Chinese patent literature CN201916970U discloses a kind of range hood on August 3rd, 2011, comprise wind cabinet, exhaust fume collecting hood, air-ducting ring, lubricating cup, glass front plate and illuminating lamp, described exhaust fume collecting hood comprises the smoke collecting chamber of front frame and open front, the angle that has an acute angle between the base plate of described smoke collecting chamber and rear plate, the intersection of base plate and rear plate has draining hole; Smoke collecting chamber is positioned at wind cabinet, and and wind cabinet between gapped; Draining hole is communicated with lubricating cup, and the inner chamber of wind cabinet is communicated with lubricating cup; Also comprise a cowling panel, gapped between the rear plate of cowling panel and smoke collecting chamber, cowling panel is connected with rear plate; Cowling panel circumferentially with the hole of glass front plate circumferential between gapped.
In conventional art, the power of the smoke absorption effect of smoke exhaust ventilator is mainly determined by the power of its wind cabinet, but excessive power can cause its operating noise to increase, too small power can cause completely oil smoke being extracted out, and in oil smoke aspiration procedure, can pass through wind wheel, after long-term use, wind wheel is stained with greasy filth, greatly reduces its suction effect, even can cause motor to be scrapped.Therefore, require further improvement.
Utility model content
The purpose of this utility model aims to provide in a kind of simplicity of design, rational in infrastructure, oil smoke passage without wind wheel, noise is low, suction oil smoke is effective, be easy to clean or exempt from the range hood cleaning, to overcome weak point of the prior art.
By a kind of range hood without wind wheel of this object design, comprise exhaust fume collecting hood and wind cabinet, its architectural feature is that wind cabinet comprises oil smoke passage, oil smoke passage one end connected set petticoat pipe, one end is by pipeline communication common flue in addition, and its architectural feature is to be provided with in oil smoke passage the guide ring for generation of high pressure draught, described guide ring inner hollow, which is provided with the venthole that some directions are consistent or go out compression ring, end is provided with air inlet; Described oil smoke passage is provided with gas outlet, and one end, gas outlet and air inlet are by screw thread or clamp connection, and other one end, gas outlet is communicated with the high pressure draught generating means of oil smoke passage outside.
Described guide ring is rounded, oval or other Curved Continuous are curved.
Described high pressure draught generating means is vortex fan, centrifugal blower or high-pressure pump.
The utlity model has following beneficial effect:
In wind cabinet, without the structure of wind wheel type, make the operating noise of range hood extremely low, guide ring produces high pressure draught and form negative pressure in oil smoke road, indoor oil smoke is discharged to smoothly outdoor, suction oil smoke is effective, and the detachable design of guide ring makes range hood inside more easily clean or exempt from and cleans.
The utlity model has that novel structure uniqueness, noise are low, suction oil smoke is effective, be easy to clean or exempt to clean, long-lived feature.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the top view of the utility model one guide ring.
Fig. 3 is the top view of the utility model one guide ring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Referring to Fig. 1-Fig. 2, this is without the range hood of wind wheel, comprise exhaust fume collecting hood 1 and wind cabinet, its wind cabinet comprises oil smoke passage 3, oil smoke passage 3 one end connected set petticoat pipes 1, and one end is by pipeline communication common flue in addition, in oil smoke passage 3, be provided with the guide ring 4 for generation of high pressure draught, guide ring 4 inner hollow, which is provided with the venthole 5 (as shown in Figure 2) that some directions are consistent or go out compression ring 8 (as shown in Figure 3), and end is provided with air inlet 7; Oil smoke passage 3 is provided with gas outlet 6, and 6 one end, gas outlet are connected by screw thread (or clip) with air inlet 7, and other one end, gas outlet 6 is communicated with the high pressure draught generating means of oil smoke passage 3 outsides
The high pressure draught that high pressure draught generating means (the present embodiment is vortex fan 2) produces flows into guide ring 4 from gas outlet 6, discharge from venthole 5 (or going out compression ring) again, oil smoke passage 3 tops are produced toward the consistent air-flow of smoke pipe blow-off direction, oil smoke passage 3 belows produce by exhaust fume collecting hood 1 negative-pressure air-flow to oil smoke passage 3 directions simultaneously, thereby reach, indoor oil smoke are expelled to common flue or outdoor.Because gas outlet 6 is connected by screw thread (or clip) with guide ring air inlet 7.When guide ring 4 need to clean, guide ring 4 is backed out to (or pulling up) from gas outlet 6, very convenient.
Further, guide ring 4 is rounded, oval or other Curved Continuous are curved, for example heart etc.
In the present embodiment, high pressure draught generating means 2 is adopted as vortex fan 2 (or centrifugal blower), and it is applicable to general family and uses.High pressure draught generating means 2 can be preferably and oil smoke passage 3 be arranged side by side, improve space availability ratio, the inlet channel of high pressure draught generating means can be separately directly communicated with to ensure air input with outdoor.
In addition, high pressure draught generating means can also adopt high-pressure pump to substitute.
If this range hood without wind wheel reaches commercial batch while installing, high pressure draught generating means can adopt high-pressure pump to replace.High-pressure pump output is directly connected with cigarette machine gas outlet 6, and corresponding every range hood is provided with a high pressure draught valve switch, uses separately to meet range hood.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
