During the vacuum cleaner operation, transmitter 127 and receiver 137 sustainable energisings, and can continue to monitor the signal that receiver 137 produces through logic control element.In another embodiment, transmitter 127 can be switched on when vacuum cleaner moves beginning or end of run with receiver 137, perhaps alternate energisation, and the time interval monitoring signal to disperse.In another embodiment, logic control element possibly inferred separation chamber 110 by dust and/or discarded object obstruction when starting vacuum cleaner, then can get clogged with the indication separation chamber by bright lamp.Assessed after the signal from receiver 137, if logic control element is confirmed separation chamber 110 not by total blockage, then logic control element can make the lamp outage, and separation chamber 110 does not get clogged with indication.Logic control element can continue the signal that monitoring receiver 137 sends then, or possibly restart before the vacuum cleaner not the signal that can monitoring receiver 137 sends.
Certainly, can calibrate transmitter 127 and receiver 137, to count reality or expected loss through the energy of clean or empty separation chamber 110.In this case; Can (for example calibrate in factory; Through simple loss factor (loss factor) is counted logic control element); Maybe can in use calibrate (for example, through when separation chamber 110 is drained, resets the baseline loss level of sensor or the hand-reset button is set at every turn) as the baseline loss during cleaning through the loss of signal after will cleaning at every turn.Can calibrate transmitter 127 and receiver 137; If do not have to find through the actual of clean or empty separation chamber 110 or expect that energy loss (promptly; The energy that receiver 127 receives is higher than the expection energy through clean or empty separation chamber 110), then can recognize separation chamber 110 is not installed or install improper.Under separation chamber 110 not being installed or situation is installed improperly, logic control element maybe not can allow the motor (not shown) to start, if perhaps motor is moving then can stop its operation.Logic control element also can be lighted wrong indicator lamp (error light) or similar indicator, installs improper or does not find to remind separation chamber 110.Also can locate and be provided with transmitter 127, receiver 137, so that they rely on the window 120,130 separately, with energy drag receiver 137 with transmitter 127 emissions.In such embodiment, only if dust discrete group component 100 correctly is installed in the housing 105, otherwise receiver 137 can not receive any appreciable energy from transmitter 127.This embodiment can be used for indicating dust discrete group component 100 that correct malfunction is not installed.
As known in the art, can use type and/or amount or other function above-mentioned and/or that other control method provides indication to pass through the dust of separation chamber 110 as the user, the separation chamber does not find like indication.
When starting vacuum cleaner, the motor (not shown) produces vacuum.Air and dust are inhaled into vacuum cleaner via import 102.Through import 102 air and dust are imported separation chamber 110, wherein separate the shape of locular wall, import and the pressure differential between import and the outlet produces one or more whirlwind or other is essentially circumference formula or screw type airflow pattern.As known in the art, one or more filters or screen pack can be set in separation chamber 110 stay the air in the separation chamber 110 to help producing whirlwind and/or filtration.Vacuum cleaner can comprise single whirlwind, or as in the illustrated embodiment, can comprise the multicell cyclone separation system.In the embodiment shown, separation chamber 110 (transmitter and receiver move therein) is the first order cyclone separator 140 of two Room cyclone separation systems.The filter (not shown) can be arranged in separation chamber 110, and window can be positioned at the following of filter or consistent with filter height with sensor, but the direction that window and sensor be set makes filter can not hinder the operation of sensor.The air of staying in the first order cyclone separator 140 gets into secondary cyclone 150, secondary cyclone 150 with the solids precipitation that removes in the chamber that is attached thereto 152.
As known in the art, in separation chamber 110, air generally rotates with respect to the tangential direction of separation chamber's 110 walls.Though embodiment described herein is called " cyclone separator (cyclone) ", it should be understood that, embodiment can use with the whizzer of any kind, even can use with the device that does not use centrifugal or tornado flow.This rotation uses radial centrifugal force 110 inside to push dust the wall of separation chamber 110 to from the separation chamber.Along with dust and larger particles are separated, they are easy to be deposited in the bottom 142 of separation chamber 110.There is a problem in cyclone separating chamber, and after vacuum cleaner run duration and operation, dust and dust are easy to adhere on separation chamber's 110 walls.The dust of these adhesions may reduce the signal strength signal intensity that arrives receiver 137, thus the operation of victim emitter 127 and receiver 137.
Consult Fig. 5 now, show the example cross section of separation chamber 110, wherein the air in arrow indication boundary layer (boundary layer) of 110 inwalls along contiguous separation chamber flows.The inner surface of wall comprises example raised portions 510, and it can be internal emission window surface 121 or the inner window surface 131 that receives.Only exemplaryly among this figure show a window surface, but similarly analyze with the result can be in a plurality of outstanding window surface acquisitions.As shown in the figure, air centers on separation chamber 110 and flows, and air is directed away from outer wall when it flows through jut 510.According to the reason that well-known principle of hydrodynamics is explained, its speed can increase when air is flowed through jut 510.When air was flowed through jut 510, the boundary layer of the whirlwind air in the separation chamber 110 possibly also can reduce.Under the situation that does not receive any operation theory constraint, think that air velocity that increases at jut 510 places and the boundary layer size that reduces help from jut 510 surface removal dust granules.Catharsis (but general other all places that can not appear at separation chamber's 110 walls) is provided like this, has helped to make can not accumulate dust on the jut 510 and help its normal operation.Air velocity through jut 510 (as shown in the figure or form launch window and/or the similar jut of receive window) can increase by 10%, 40%, 50% or more.For example, according to calculating, air velocity can increase to about 11 meter per seconds, about 14 meter per seconds or about 15 meter per seconds (position of jut 510 is set) from about 5-10 meter per second (not having jut).In once simulating; According to calculating; The jut that increases increases to the air-flow velocity of the jut of flowing through not exist the about 150% of jut position, and boundary layer (being the air-flow part between wall surface and the position that obtains peak velocity) is decreased to about 80% of jut position is not set.
Air-flow among Fig. 5 is represented the whirlwind that turns clockwise, but also can be rotated counterclockwise.Further, can optimize jut 510 to specific direction of rotation (promptly clockwise or counterclockwise).Also can be along helical trajectory orientation projection portion 510, to meet moving both vertically of air-flow.If desired, can be provided with and help to make air with the flow through functional part of jut of mode of rule.For example can current control plane (flow control plane) be set along the upper wall and the lower wall of each jut.According to the present invention, other variation is conspicuous to those skilled in the art.
A special advantage of some embodiments of the invention (this advantage is not to be that all embodiment are required certainly) is under the situation that does not remove transmitter 127 or receiver 137, can separation chamber 110 removed and clean, safeguards and/or replace from housing 105.The launch window 120 that is connected to separation chamber 110 can remove to clean with separation chamber 110 with receive window 130.The inner surface of user separation chamber 110 capable of washing (comprising inner receive window 130 and internal emission window 120) removing the accumulation dust that the air velocity be not increased and the boundary layer that reduces remove, thereby returns to optimal operational condition with equipment.For this reason, launch window 120 is formed with jut with receive window 130 and has extra advantage, and vision and sense of touch indicant promptly are provided, and helps the user in cleaning process, to find the place that should be noted that.Though possibly expect to carry out such cleaning, maybe not can need carry out such cleaning, the user usually can be not specially in regularly cleaning clean window 120, window 130.In case clean, then the user may change the separation chamber 110 in the housing 105.During separation chamber 110 in the user changes housing 105, launch window 120 is arranged in the housing 105, and transmitter 127 operationally is transmitted into electromagnetic energy in the separation chamber 110 like this.Receiver 137 is set receives from separation chamber 110 and the electromagnetic energy transmitted through receive window 130 it.Therefore, this exemplary embodiment not only provides automatic cleaning function during use, and makes the user clean launch window 120 and receive window 130 in one way; And if window remains in the housing 105 or if transmitter 127 can not separate with separation chamber 110 with receiver 137, then this mode can not be carried out.Although the description of preceding text is arranged, in an alternative embodiment, transmitter 127 and/or receiver 137 can be connected to housing 105, and can not remove from housing, maybe can be through circuit and transmitter 127 and/or receiver 137 being broken off and it being removed.
In another embodiment of the present invention, launch window 120 and/or receive window 130 can be formed by elastomeric material.Therefore be used for the use of the deformable window of launch window 120 and/or receive window 130, can allow when vacuum cleaner brings into operation and/or finish, the dust and the discarded object of window to be cleaned out.Receive window 130 or launch window 120 can be formed by elastomeric material, or receive window 130 all can be formed by elastomeric material with launch window 120.If receive window 130 or launch window 120 are formed by elastomeric material, other part can form jut (as implied above) or be shaped by different way in separation chamber 110 so.
The instance of deformable window is shown among Fig. 7.Show elastic emission window 710 and transmitter 127 in the drawings simultaneously.Elastomeric material can make transmitter 127 electromagnetic energy emitted get into separation chamber 110.For example, for transmitter 127 electromagnetic energy emitted, elastomeric material can be optical clear or transparent basically.The elastomeric material casting forming is " static " state (as shown in Figure 7), but its deformable is at least a " activity " state (as shown in Figure 8), and the geometry of window and " static " state is different when being in " activity " state.In the illustrated embodiment, window 127 is rendered as substantially paraboloidal shape, 110 outside extend in the separation chamber with inactive state, and opposite basically with the shape of active state.Yet in other embodiments, can use other shape.
In a preferred embodiment, window 710 is suitable for from the inactive state to the active state and then gets back to the repeatedly distortion of inactive state.The deemed appropriate material of PETG, this material is firm relatively, shock-resistant and be transparent.The speed (vice versa) of material from the inactive state to the activity state transition possibly be progressive or relatively fast.Preferably, conversion rates is quick relatively, to help removing discarded object through the transformation of quick acceleration and/or deceleration window 710.
As shown in Figure 8, when vacuum cleaner moved, separation chamber's 110 inner air pressures descended and are lower than separation chamber's 110 air outside pressure.This pressure differential causes 710 bendings of elastic emission window or distortion to get in the separation chamber 110, makes elastic emission window 710 be positioned at active state.Distortion in the elastic emission window 710 entering separation chambers 110 can be removed dust or other discarded object that adheres on the launch window 710, thereby has removed the part or all of discarded object on the elastic emission window 710.If when starting vacuum cleaner, launch window 710 is configured to be bent to relatively fast active state, then assists in removing the discarded object of any adhesion.In addition, when elastic emission window 710 was in active state, it formed jut in separation chamber 110, and the air-flow around this jut also can be removed dust and discarded object on the elastic emission window 710, as illustrated among the embodiment of front.The inner air pressure in separation chamber 110 is during less than separation chamber's 110 air outside pressure, and elastic emission window 710 can remain on active state.
When vacuum cleaner did not move, separation chamber's 110 inside and outside pressure reached balance, and elastic emission window 710 returns inactive state, and is as shown in Figure 7.When elastic emission window 710 returns inactive state, can remove dust or other discarded object accumulated on the elasticity launch window 710 in the running.In addition, elastic emission window 710 can be withdrawn from separation chamber 110, and when emptying separation chamber 110, elastic emission window 710 can not hinder the passing away of dust like this.
Though the state of window 710 takes place alternately the vacuum that the foregoing description has been described through generation in the separation chamber 110, can assist or control through alternate manner should motion.For example, can use spring is arbitrary state with window 710 bias voltages, also can use plant equipment to force window 710 to get into arbitrary state.As an instance of this set, when the vacuum fan moves, can use mechanical device to promote transmitter 127 and withstand window 710 they are moved into separation chamber 110.
Certainly, Fig. 7 and Fig. 8 also can represent receive window and receiver 137, so receive window can form by elastomeric material, and can move with the elastic emission window 710 similar modes shown in Fig. 7 and Fig. 8.In addition, elastic emission window 710 and/or receive window 130 can be along the separation chamber 110 length direction extend, as shown in Figure 6.
Fig. 9 shows another exemplary embodiment of the present invention.In such embodiment, transmitter 127 and receiver 137 can be positioned at the same side of single window 910.Be provided with signal reflex to the receiver 137 of reflector 920 with spontaneous love dart 127 in future.Reflector 920 can form or be coated with such material by reflecting some of transmitter 127 emissions or the material of whole electromagnetic energy.For example, if transmitter 127 visible emitting or infrared ray, but then reflector 920 can be coated with reflect visible light or ultrared reflecting material (for example thin foil) or formed by this material.Transmitter 127 can be launched electromagnetic energy, and this electromagnetic energy is via launch window 910 entering separation chambers 110.Receive window 920 is with some or all electromagnetic energy reflected backs separation chamber 110.Receiver 137 can receive through launch window 910 electromagnetic energy of (or alternatively, through being the independent window that receiver 137 is provided with) then, and signal is transferred to the appropriate control circuit, with the vacuum cleaner of controlling described in earlier paragraphs.Launch window 910 and/or receive window 920 can be fixing (shown in Fig. 1-6), or can be flexible (shown in Fig. 7-9), and Fig. 9 shows the window 910 and reflector 920 that remains static.Reflector 920 also can be positioned at the back of the flexible receive window 920 of suitable rigidity, and is positioned at the outside of separation chamber 110.For example, reflector 920 can be positioned on the housing 105.
