Description
Technical field
The present invention relates to a kind of cyclone, more particularly, relate to a kind of cyclone that is applicable to vacuum cleaner.
Background technology
Generally, cyclone is to utilize cyclonic principle to collect the device such as pollutants such as dust, fine hair and paper scraps that comprises in the air, and cyclone is used for various fields, and is mainly used in the domestic suction cleaner.
In document, various types of cyclones have been proposed as US patent 4643748, US patent 4353008, US patent 5078761, US patent 145499 etc.
Cyclone with two types: a kind of forwards to cyclone, air (contaminated air) direction that is imported that wherein comprises pollutant is roughly the same with the direction of the air that is cleaned discharge; And a kind of reverse cyclone, wherein said all directions are different.
The unidirectional cyclone of prior art will be described in detail.
The cyclone of prior art comprises the gatherer of the suction of air wherein at cyclone body (Fig. 1 and 2) of axially carrying out, and wherein the suction of air at other gatherers that tangentially carry out (Fig. 3 and 4).
Describe the embodiment of the unidirectional cyclone of prior art in detail with reference to Fig. 1 and Fig. 2.
Be used for being formed on a side of cylindrical cyclone body 1, and the air that is used for being cleaned is formed on its opposite side at the air outlet slit 4 of axially discharging at the suction inlet 2 of axially drawing contaminated air.The device 3 that is used to supply with is formed on the inboard of cyclone body 1 so that axial inhaled air is rotated on tangential direction.Pollutant outlet 5 is formed on air outlet slit 4 and sentences the pollutant that is separated by centrifugal force is guided on tangential direction, and collecting bag 6 is removably mounted on pollutant and exports on 5 the side.Shown in Fig. 3 and 4, another embodiment of the cyclone of prior art has similar structure basically, and except being not used in the isolated system that revolving force is provided, this is because suction inlet 12 is arranged on the tangential direction of cyclone body 11. Reference numeral 13,14 and 15 indicates air outlet slit, pollutant outlet and collecting bag respectively.
Simultaneously, above-mentioned cyclone is being applied under the situation of vacuum cleaner, cyclone can be installed in the vacuum cleaner main body or be installed between main body and the suction inlet housing.
The work of the cyclone of prior art is described with reference to Fig. 1 and Fig. 2.
When cyclone is worked, come into operation to produce suction such as the suction generating device of air exhauster (not shown), pollutant is inhaled into cyclone body 1 with air by suction inlet 2 simultaneously.
At this moment, axially the contaminated air that sucks passes the revolving force that is used to the device 3 of revolving force is provided and is endowed tangential direction, and causes contaminated air to rotate in cyclone body 1.So light relatively air converges to the center of cyclone body 1 and forms whirlwind, this is because light relatively air is subjected to less centrifugal force.When the air stream (discharge air) in the air outlet slit direction formed with certain momentum, this air was promptly discharged by air outlet slit 4.
On the other hand, heavier-than-air pollutant obtains bigger centrifugal force, and flows along the inwall of cyclone body 1, is installed in the collecting bag 6 that pollutant exports 5 places thereby move to.
When being collected in the collecting bag 6 more than a certain amount of pollutant, the user can separate collecting bag from pollutant outlet 5, and pollutant is removed, and then collecting bag is connected in the pollutant outlet 5 in order to reusing.
The operation principle of another embodiment of the cyclone of prior art is similar to above-mentioned work, except contaminated air is obtaining under the situation that is not used in the isolated system that revolving force is provided the centrifugal force, this is because contaminated air enters the cyclone body in tangential direction.
The reverse cyclone of prior art is described with reference to Fig. 5.
Simultaneously, with forwards to cyclone different, in reverse cyclone, be used to discharge the air outlet slit 34 that purifies air and be formed on suction inlet 32 formed places, that is, be formed on the axial top of rotoclone collector body 31.
The work of aforementioned reverse cyclone below will be described.
The contaminated air that is drawn in the suction inlet 32 rotates and descends simultaneously along the inwall of cyclone body 31.In this process, pollutant separates with cyclone body 31 and is collected in the collecting bag 35.Simultaneously, the suction that the air that is cleaned applies by air outlet slit 33 changes direction and is moved upwards up to air outlet slit 33 from cyclone body 31 bottoms, thereby is rejected to the outside of cyclone body 21.
That is to say that in reverse cyclone, the air-flow (whirlpool) that rotates along cyclone body 1 inwall becomes the discharge air stream that (air outlet slit relatively) changes direction and move up in cyclone body bottom.Yet the cyclone of prior art has some problems.
At first, because the contaminated air that is inhaled in the cyclone body can not obtain enough big centrifugal force, pollutant can not collected effectively, but is discharged into the external side of cyclone with discharging air, thereby has reduced dust catching efficiency.
Secondly, vortical flow that forms in the cyclone body and discharge air-flow interfere with each other, and produce flow resistance, thereby have increased the pressure loss and noise.This problem is particularly serious in reverse cyclone.Because when air-flow is transformed into the discharge air-flow, the air-flow that rotates in cyclone body bottom collides with discharging air-flow, thereby produces the warm air that act as the air barrier element.
Summary of the invention
