If be described more specifically the structure of electric dust collector of the present invention, then possess: the suction tool of the dust of the quilt cleaning face on attraction ground etc.; Attraction contains the electric blowing machine from the air of the dust of above-mentioned suction tool; The electric dust collector main body of this electric blowing machine is equipped with in inside; Importing contains the air of the dust that is attracted by electric blowing machine, and the dust of dirt separation and air separates portion; And deposit by this dust separating part from the dust storage part of dust.Dust separation portion constitutes, and has: importing contains the attraction mouth from the air of the dust of suction tool; Contain the gyration airflow ventilating duct that flows through as gyration airflow from the air of this attraction mouthful dust that imports; Form at least a portion of above-mentioned gyration airflow ventilating duct and the dust removal filter of dirt separation and air, when covering the periphery of this dust removal filter, the main air duct that utilization connects to the attraction side of electric blowing machine is from the attraction of the outer circumferential side effect electric blowing machine of dust removal filter.
For gyration airflow takes place, the gyration airflow ventilating duct is made roughly cylindric, preferably cylindric, at the internal face of this gyration airflow ventilating duct and along the circumferential direction and form the attraction mouth of the air-flow rotate.Promptly, the attraction direction that attracts mouthful be with the direction of axial quadrature cylindraceous and is tangential direction cylindraceous, so that along the circumferential flow of inner wall surface thereof.What is called is roughly cylindric, contains in the section shape of the face of quadrature axial polygon for ellipse, octagonal etc. with it, importantly, as long as generation is along the shape of the circumferential gyration airflow of the internal face of gyration airflow ventilating duct.
In addition,, need in the gyration airflow ventilating duct, act on the attraction of electric blowing machine certainly, to produce negative pressure state in order in the gyration airflow ventilating duct, gyration airflow to take place.Thus, cover an end of the attraction mouth that is provided with gyration airflow ventilation unit roughly cylindraceous with the top of dust-collecting box, the other end and dust storage part are and are tightly connected, as long as from the attraction of the dust removal filter partial action electric blowing machine that is formed on the gyration airflow ventilating duct at least.
As preferred mode, the secondary air channel that acts on the attraction of electric blowing machine can be connected with the connecting portion or the dust storage part itself of gyration airflow ventilating duct and dust storage part.Utilize this structure, not only obtain the attraction of dust removal filter part, also can obtain more, passed through that the dust of dust removal filter is easier to be moved to the dust storage part near the attraction at dust storage part place.
Even an end in secondary air channel is made with the part of dust storage part be connected, the attraction side or the other end that the other end is connected to electric blowing machine are connected with a main air duct part that has formed, and all can obtain identical effect.Be preferably made in one of secondary air channel and distolateral the 3rd dust removal filter be installed, do not flow into electric blowing machine one side so that accumulate in the dust of dust storage part.Especially for the attraction that makes electric blowing machine affacts dust storage part side by secondary air channel, the 3rd dust removal filter preferably adopts screen cloth not allow susceptible to plugging structure.
Therefore, by the 3rd dust removal filter is made the filter that thick dirt is caught usefulness, thereby screen cloth is not easy to stop up, and can stand long use.On the other hand, owing to make thick dirt filter, thin dirt has the possibility that flows into secondary air channel, so if directly enter the attraction side of electric blowing machine, then the durability of electric blowing machine reduces.Thus, in the occasion of the 3rd dust removal filter being made thick dirt filter, thin dirt filter need be arranged on upstream by the attraction side of electric blowing machine.
About this thin dirt filter, if the dust removal filter that will be positioned at main air duct is as thin dirt filter utilization, as the method that secondary air channel is connected on the main air duct, can be set forth in auxiliary connection air channel on the main air duct of the upstream side that is positioned at the thin dirt filter that constitutes dust removal filter.Utilize this connection, can catch thin dirt from secondary air channel with the thin dirt filter that constitutes dust removal filter.In addition, utilize this method of attachment, can get rid of thin dirt filter other preparation, the special use of secondary air channel, can improve the maintainability of thin dirt filter.
In addition, in above-mentioned concrete dust catcher, have the gyration airflow of utilization self purification effects though be arranged on the dust removal filter of dust separation portion, owing to be the structure that the periphery from dust removal filter attracts, the screen cloth that can't suppress fully to cause because of dust stops up.For this reason, be provided with the dust that is used to remove the dust that has stopped up dust removal filter and remove mechanism, make dust remove mechanism action constantly when the dust catcher entry into service, when running finishes etc., to remove the dust that has stopped up dust removal filter, can not make attraction, attract power to reduce, can use for a long time.
Make dust remove the timing of mechanism's (also being referred to as dedusting mechanism) action, preferably set as follows, promptly in the cleaning that reality is used, the screen cloth which kind of degree takes place in dust removal filter in research stops up, and kind, the mode of dust filter of structure, the use of portion of separating with designed dust set with conforming to.Particularly, the certain hour in when beginning running makes dedusting mechanism work, and the certain hour when running finishes makes dedusting mechanism work, have again when the running beginning and when end both certain hours, make dedusting mechanism work.In order to make dedusting mechanism work, preferably utilize motor with such timing.
For example, utilize microcomputer can realize the control that the connection of motor disconnects simply,, the Motor Control of dedusting mechanism simply can be packed into as the part of a succession of action of the control part (generally realizing) of the running control of management dust catcher integral body with microcomputer.
The control of dedusting mechanism it is also conceivable that and utilizes the electric wire winding mechanism that is contained in electric dust collector inside except using above-mentioned motor.Just, when the user pulls out the power line that is wound on the electric wire winding mechanism for entry into service, then the electric wire winding part of electric wire winding mechanism utilizes its pullout forces and rotates, if this revolving force is sent to dust removes mechanism, then dust is removed mechanism and just moved when the running beginning.In addition, usually, in the electric wire winding mechanism, disc spring is housed, if pull out power line, the then electric wire winding part of electric wire winding mechanism rotation, the disc spring of interior dress is rolled.And, for winding cables when finishing running, when pushing the coiling button of electric wire winding mechanism (usually, being configured to push the part of electric dust collector main body), the power of the disc spring that utilization is rolled makes electric wire coiling portion rotate with the rolled power line to the direction of rolled power line.If the revolving force of general electric wire coiling portion at this moment is sent to dust and removes mechanism, then when finishing, running can make dust remove mechanism action.
Like this, can suitably select to make dust remove the method for mechanism action, but when at least when the running of electric dust collector begins, when running makes dust remove mechanism action when finishing, then the screen cloth that can eliminate dust removal filter when being each running of cleaning stops up, when each cleaning is turned round, can keep initial attraction, suck the big performance of power.And by adopting above-mentioned dust to remove mechanism in the structure of stopping up at the screen cloth that in the structure of the outer circumferential side of dust removal filter, promptly utilizes self catharsis can suppress dust removal filter attraction force acts, thereby this screen cloth can not take place in stopping up for a long time, can not need to safeguard in long-time.In addition, can shorten the actuation time that dust is removed mechanism and be equivalent to screen cloth and do not allow susceptible to plugging actuation time, removing with Motor Drive dust in the structure of mechanism, even make its action when the running of electric dust collector begins, when turning round end, the user of electric dust collector carries out the transition to the cleaning action or the arrangement of cleaning back is not taken time and energy, and ease of use is good.
Below, embodiments of the present invention are described.
