In electric dust collector, form make to suck the air suction way that gas passes through member due to charged with sucking gas friction.In addition, owing to sucking gas and dust friction, make dust charged.Particularly making to suck during thereby gas rotating makes to suck the electric dust collector that gas and dust separates, owing to sucking the internal perisporium surface rotation of gas along dust storage chamber, so dust storage chamber is easily charged.In addition, because the dust charged with sucking gas friction also rotates together with suction gas in dust storage chamber, so contact with charged dust because of dust storage chamber, make dust storage chamber also charged.
If the dust of dust storage chamber or dust storage chamber inside is charged, can produce following problem.That is to say, when user's removing of electric dust collector is deposited in the dust in dust storage chamber, dust is attached in dust storage chamber, is difficult to remove fully, and dust can fly out and disperse towards periphery from dust storage chamber sometimes.In addition, when user's removing of electric dust collector is deposited in the dust in dust storage chamber,, there is the danger of getting an electric shock in the dust storage chamber of user's hand contact electrification.
Charged in order to prevent dust or dust storage chamber, for example, can consider provides ion to sucking gas.As to sucking the electric dust collector that ion is provided in gas, the following electric dust collector has been proposed.
Japanese Patent Publication communique JP has been put down in writing a kind of electric dust collector with connector for No. 2004-194977, when not cleaned, this connector is installed on the suction inlet of main body of dust collector and is replaced hose.Be assembled with anion generator in this connector.If be installed on the electric blowing machine that drives dust catcher under the state on the suction inlet of main body of dust collector at connector, together with the air-flow of anion and the connector of flowing through, be provided in main body of dust collector.In addition, by shrinking wind path, the wind path of connector is shunk, the air velocity when airflow velocity ratio of the connector that can make to flow through cleans usually is fast.The dust film that utilizes this air-flow to peel off to be attached on filter.In addition, owing to together with this air-flow, providing anion, so in anion and filter charged, thereby easily peel off dust.
Japanese Patent Publication communique JP has been put down in writing a kind of electric dust collector with neutralizer for No. 2006-158568, and this neutralizer is arranged on the outside of disposal box, for disposal box being removed to electricity.Neutralizer has the part be connected with disposal box, can to disposal box with static discharged, also can by neutralizer produce in static and disposal box on static.In addition, can also in air, produce anion, utilize anion to remove electricity.
Japanese Patent Publication communique JP has been put down in writing a kind of electric dust collector No. 2004-154214, and this electric dust collector has ion generating apparatus from electric charge to the dust collecting part consisted of the grid filter that send, alleviates the obstruction of dust collecting part.
Japanese Patent Publication communique JP has been put down in writing a kind of electric dust collector with the ion generator that can produce cation or anion for No. 2003-153831.In this electric dust collector, the air suction way that ion generator is arranged on the dust collect plant upstream midway.In addition, in this electric dust collector, ion generator is connected with the end face of dust pocket for making air rotation.Open communication on the outlet of the ion current of ion generator and the end face that is formed on dust pocket.
But, in the electric dust collector of No. 2004-194977, Japanese Patent Publication communique JP, need the hose of changing mounted connector and cleaning use to use.By shrinking wind path, the wind path of connector is shunk, the air velocity during airflow velocity ratio cleaning of the connector that makes to flow through is fast.If air velocity is accelerated, suck gas and dust, connector or form the friction increasing between the member of electric dust collector.If friction strengthens, dust or each member are more easily charged.Its result, being difficult to utilize from connector provides the anion come effectively dust or each member to be removed to electricity.
In addition; in the electric dust collector of No. 2006-158568 record of Japanese Patent Publication communique JP; even can remove electricity to disposal box, can not be to flowing into the dust in disposal box or more by the member of upstream formation electric dust collector air suction way, removing electricity than disposal box.Thus, due to can not be in advance to dust or suck the member that gas contacts and remove electricity, there is larger carried charge so flow into the interior dust of disposal box.If the dust that carried charge is large contacts with disposal box, the charged quantitative change of disposal box is large, sometimes also can cause being difficult to disposal box itself is removed to electricity.
In addition, in the electric dust collector of putting down in writing for No. 2003-153831 in electric dust collector and the Japanese Patent Publication communique JP of No. 2004-154214 record of Japanese Patent Publication communique JP, due to the flow through ion current outlet of ion generator (ion generating apparatus) of the suction gas that includes dust, so easily make ion generator dirty.If ion generator is dirty or dust is deposited in the ion current outlet, the plug ion flow export is difficult to produce ion thereby hinder electric discharge.If be difficult to produce ion, can not in dust storage chamber, provide ion, also just can not effectively to dust storage chamber, remove electricity.
Summary of the invention
The object of the present invention is to provide and a kind ofly can be effectively dust or the member that forms air suction way be removed to electric electric dust collector.
The invention provides a kind of electric dust collector, it comprises: the suction inlet member has suction inlet; Electric blowing machine, for generation of sucking gas; Air suction way, from the suction inlet member to electric blowing machine, guiding sucks gas; And ion generating unit.Be formed with in air suction way and send mouth, the described mouth of sending for sending the ion produced by the ion generating unit in air suction way.Electric dust collector of the present invention also comprises wall section, and described wall section is configured in the inside of air suction way, covers the upstream of sending mouthful sucked on gas flow direction.
Send the ion produced by the ion generating unit from sending mouth in air suction way.The ion be sent in air suction way is guided to electric blowing machine together with suction gas.The upstream of sending mouth is configured in the wall section covering of air suction way inside.Therefore, the dust be included in the suction gas in the air suction way of flowing through is difficult to flow backwards to ion generating unit one side from sending mouth.Thus, by preventing dust, with the ion generating unit, contact, can prevent that the dust obstruction from sending mouth or the ion generating unit is dirty, thereby can prevent that the ion generating unit is difficult to produce ion.
Thus, can provide a kind of and can be effectively dust or the member that forms air suction way be removed to electric electric dust collector.
In electric dust collector of the present invention, preferably, also comprise dust storage chamber, in described dust storage chamber configuration air suction way, make to suck gas rotating and carry out dirt separation.The dust storage chamber preferred disposition is in the downstream of sending mouth sucked on gas flow direction.
In making to suck the dust storage chamber that gas rotating carrys out dirt separation, easily produce the friction, the friction between dust, suction gas and the friction of dust storage chamber and the friction of dust and dust storage chamber that suck gas and dust, thereby easily make dust and dust storage chamber charged.Therefore, by dust storage chamber being configured in to the downstream of sending mouth sucked on gas flow direction, can be being used for dust storage chamber is removed to electricity from sending a mouthful ion of sending to air suction way.
In electric dust collector of the present invention, preferably, the downstream end of wall section is configured to more rely on downstream than the downstream end of sending mouth sucked on gas flow direction.
Be configured to more rely on downstream than the downstream end of sending mouth sucked on gas flow direction by the downstream end wall section, thereby the downstream end of swimming over to from sending mouth is covered by wall section.Thus, can more effectively prevent that the dust obstruction from sending mouth or the ion generating unit is dirty.
In electric dust collector of the present invention, preferably, the ion generating unit produces cation and anion.Sending mouth preferably includes the cation of sending cation and sends mouthful and send the anion of anion and send mouth.The preferred ion generating unit has separating member, and described separating member is configured in that cation is sent mouthful and anion is sent between mouth.
By making the ion generating unit produce cation and anion, and send mouth from cation and send cation, send mouth from anion and send anion, thereby can provide cation and these two kinds of ions of anion to sucking in gas.In addition, by the ion generating unit being had be configured in cation to be sent mouthful and anion is sent the separating member between mouth, can prevent from before sending and mouthful sending cation and anion cation and anion neutralization and disappear.Thus, the easy parts to dust or formation electric dust collector remove electricity.
In electric dust collector of the present invention, preferably, separating member is configured to suck gas flow direction parallel.
By separating member being configured to suck gas flow direction parallel, cation and anion, along the direction arrangement with sucking gas flow direction and intersecting, are sent in air suction way.Send the cation sent of mouth and send from anion the anion that mouth is sent from cation, along arranging with sucking the direction that gas flow direction intersects, and utilize suction gas to flow through in air suction way.By cation and anion edge and the direction that the suction gas flow direction is intersected are arranged, and in the air suction way of flowing through, thereby make cation and anion be difficult to mix in air suction way.Thus, can prevent that cation and anion from colliding mutually, generation neutralizes and disappears.
In addition, the present invention also provides a kind of electric dust collector, and it comprises: the first suction inlet member has for sucking the suction inlet of gas and dust; The second suction inlet member, have for sucking the air entry of gas; Electric blowing machine, for generation of sucking gas; Air suction way, suck gas from the first suction inlet member and the second suction inlet member to the electric blowing machine guiding; And the ion generating unit, be configured in the inside of the second suction inlet member.
Be formed with in air suction way and send mouth, the described mouth of sending for sending the ion produced by the ion generating unit in air suction way.Electric dust collector of the present invention also comprises non-return valve, and described non-return valve is configured in air entry or sends mouth upper, can make air entry or send mouth to open or close.The pressure of non-return valve based in air suction way, can make air entry or send mouth to open or close.
Be formed with two peristomes on electric dust collector, that is, and the air entry that the suction inlet that the first suction inlet member has and the second suction inlet member have.Therefore, can suck the gas that includes dust from the suction inlet of the first suction inlet member, from the air entry of the second suction inlet member, suck the gas that comprises hardly dust.Thus, because the ion generating unit that is configured in the second suction inlet component inside does not contact with the air that includes dust, so that the ion generating unit is not easy is dirty.
On the other hand, with the electric dust collector that there is no air entry, compare, even the output of electric blowing machine is identical, attraction also can reduce sometimes.While usually using, the reduction of this attraction does not have problems.But, in the situation that the pressure rise in air suction way is to a certain extent, owing in the second suction inlet member, being formed with and sending mouth, so compare attraction sometimes with electric dust collector in the past, can reduce.
Therefore, at air entry or send on mouth and configure non-return valve, for example, when the pressure of the pressure ratio regulation in air suction way is low, non-return valve is opened, and from sending, mouthful in air suction way, provides ion.In addition, when the pressure of the pressure ratio regulation in air suction way is high, non-return valve is closed, and from sending mouth, in air suction way, does not provide ion, thereby preferentially keeps attraction.
In addition, in the situation that the attraction of electric dust collector can be regulated by the user, when the user is adjusted to the attraction of electric dust collector when stronger than the attraction of regulation, non-return valve makes air entry or sends mouthful to close, thereby can make attraction become enough by force.On the other hand, when the user is adjusted to the attraction of electric dust collector when lower than the attraction of regulation, non-return valve makes air entry or sends mouthful to open, thereby can provide ion fully in air suction way.
Like this, by the pressure based in air suction way, utilize non-return valve can make air entry or send mouthful to open or close, thereby can keep the attraction of electric dust collector, and can in air suction way, provide ion.
Thus, can provide a kind of and can be effectively dust or the member that forms air suction way be removed to electric electric dust collector.
In electric dust collector of the present invention, preferably, also comprise dust storage chamber, described dust storage chamber is configured in air suction way, makes to suck gas rotating and carrys out dirt separation.The dust storage chamber preferred disposition is in the downstream of sending mouth sucked on gas flow direction.
In making to suck the dust storage chamber that gas rotating carrys out dirt separation, easily produce the friction, the friction between dust, suction gas and the friction of dust storage chamber and the friction of dust and dust storage chamber that suck gas and dust, thereby easily make dust and dust storage chamber charged.Therefore, by dust storage chamber being configured in to the downstream of sending mouthful sucked on gas flow direction, can be from sending, mouthful to air suction way, sending ion and be used for dust storage chamber remove electric.
In electric dust collector of the present invention, preferably, non-return valve is configured on air entry, can make air entry open or close.
If non-return valve is configured in and sends mouthful,, when when sending mouth and send the ion produced by ion generating element, ion collides and makes the ion disappearance with non-return valve sometimes.Therefore, by non-return valve not being configured in and sending mouth above, but be configured on air entry, can prevent ion and non-return valve collision and ion is disappeared.The ion concentration that thus, can prevent from sucking in gas reduces.
In electric dust collector of the present invention, preferably, non-return valve is configured in sends mouth above, can make to send mouth and open or close.
Thus, can prevent that the suction gas that includes dust from making the ion generating unit dirty from sending mouthful refluence.

Be provided with wheel 106 on main body 100, these wheel 106 supportive bodies 100, can move on the ground.In addition, although usually on main body 100, dispose handle (not shown), for picked up main body 100 by the user, can on main body 100, not configure handle yet.
As shown in Figure 2 and Figure 3, main body 100 internal mains at electric dust collector 1 (Fig. 1) will dispose: electric blowing machine 110, dust storage chamber 120, filter 150, air-breathing path 107A and exhaust pathway 107B.On the outer surface of main body 100 and between two wheels 106, be formed with the exhaust outlet 108 be connected with exhaust pathway 107B.
Be connected with connecting piece 105 in the upstream of dust storage chamber 120, in its downstream, by air-breathing path 107A, be connected with electric blowing machine 110.Dispose filter 150 in the downstream of electric blowing machine 110.
Be formed with ion generating chamber 130 on the outer surface of the connecting piece 105 be connected with main body 100.Be formed with ion discharge mouth 135 in ion generating chamber 130, this ion discharge mouth 135 is communicated with the inside of ion generating chamber 130 and the inside of connecting piece 105.The spaced walls 140 that ion discharge mouth 135 is used as wall section covers from the inboard of connecting piece 105.Spaced walls 140 flow in ion generating chamber 130 for preventing by the suction gas in connecting piece 105 and being included in the dust that sucks gas.From the suction gas flow direction shown in the double dot dash line of Fig. 2, observe, wall extends and bending halfway towards the central part of connecting piece 105 from the end, upstream of ion discharge mouth 135, extends and is set near the downstream end of ion discharge mouth 135 always.In other words, spaced walls 140 comprises: vertical wall, extend towards the cardinal principle vertical direction with respect to sucking gas flow direction; And horizontal wall, with respect to sucking gas flow direction, towards the cardinal principle horizontal direction, extend.
In order to prevent that the suction gas that includes dust from flowing in ion generating chamber 130, as shown in Figure 2, the shape of spaced walls 140 preferably its section is that the cardinal principle that horizontal wall is longer than vertical wall is L shaped, and is provided with gap near the downstream end of ion discharge mouth 135.
In the situation that promptly in connecting piece 105, provide ion generating chamber 130 interior produced ion, for the opening that makes ion discharge mouth 135 becomes large, preferably make the vertical wall of spaced walls 140 and the length of horizontal wall substantially equate, in this case, in order to prevent that dust from flowing in ion generating chamber 130, can arrange the opening that cancellous grid filter covers ion discharge mouth 135.
As shown in Fig. 4 (A), (B), in the internal configurations of ion generating chamber 130, have: as the ion generating element 131 of ion generating unit; Separates walls 134 as the separating member that separates cation and anion; And non-return valve 137.Be formed with two peristomes in ion generating chamber 130, that is, and ion discharge mouth 135 and air entry 136.Ion discharge mouth 135 is all the time in open state.
In addition, also can adopt the magnetic valve that air entry 136 is opened or closed by electric driver's valve to replace non-return valve 137.
In this case, the operating portion of ion generating element 131 is set on the handle of tube connector 103, according to the user, to the driving of ion generating element 131 with stop driving and switched, carries out the opening and closing by the air entry 136 of solenoid control.
In addition, under the state be connected with main body 100 at connecting piece 105, air entry 136 is configured to its opening downward.Thus, even, in the situation that the liquid such as water enter in ion generating chamber 130, also can promptly it be discharged to outside.
Below the action of the electric dust collector 1 of formation is in the above described manner described.At Fig. 2, in Fig. 4, the arrow shown in double dot dash line means to suck gas flow direction.At first, to the dust amount that is deposited in dust storage chamber 120 inside few situation, be that the low situation of pressure in air suction way describes.
If the user operates to make electric dust collector 1 entry into service to operating portion, ion generating element 131 and electric blowing machine 110 are driven.If ion generating element 131 is driven, produce ions in the cation generating unit 132 of ion generating element 131 and anion generating unit 133 respectively.
If electric blowing machine 110 is driven, produces and suck gas.From suction inlet, suction gas is drawn into to the inside of suction inlet member 101.Be inhaled into the suction gas of suction inlet member 101 inside successively by extension tube 102, tube connector 103, inhaling hose 104 and connecting piece 105, thereby be inhaled in the main body 100 of electric dust collector 1.In main body 100, suck gas and at first flow in dust storage chamber 120 from connecting piece 105.
In the situation that almost do not pile up dust in dust storage chamber 120, low as the pressure in the connecting piece 105 of an air suction way part.Now, the non-return valve 137 be configured on air entry 136 is opened air entry 136.Therefore, if electric blowing machine 110 is driven, also produce the suction gas that is drawn into ion generating chamber 130 inside from the air entry 136 of ion generating chamber 130.
The suction gas flow in ion generating chamber 130 from air entry 136 passes through cation generating unit 132, flow into the inside of connecting piece 105 from ion discharge mouth 135.In addition, the suction gas flow in ion generating chamber 130 from air entry 136 passes through anion generating unit 133, flow into the inside of connecting piece 105 from ion discharge mouth 135.When sucking gas by cation generating unit 132 and anion generating unit 133, to sucking in gas, provide positive and negative ion.The suction gas that includes ion that flow into connecting piece 105 inside from ion discharge mouth 135 flows to dust storage chamber 120 is interior.
The upstream of ion discharge mouth 135 is spaced apart wall 140 and covers.Therefore, flow into the suction gas that includes dust in connecting piece 105 from suction inlet member 101 by extension tube 102, tube connector 103 and inhaling hose 104, from the upstream of ion discharge mouth 135 along the spaced walls 140 that covers ion discharge mouth 135, to the downstream flow of connecting piece 105.Upstream due to spaced walls 140 covering ion discharge mouths 135, be difficult to enter in ion discharge mouth 135 so include the air of dust.Therefore, can prevent the dust plug ion send mouthfuls 135 or the suction gas that includes dust enter in ion generating chamber 130 cation generating unit 132 or anion generating unit 133 made dirty by dust from ion discharge mouth 135, thereby can prevent from being difficult to producing electric discharge.
By making the air that includes ion in connecting piece 105 internal flows, the dust in connecting piece 105 and connecting piece 105 is removed to electricity.
Then, the suction gas that includes ion flow in dust storage chamber 120 from connecting piece 105, and produces rotation.Now, suck the ion and the dust collision sucked in gas in gas.And, the ion in suction gas and the internal perisporium surface collision of dust storage chamber 120.
Suck dust in gas usually due between the friction with sucking gas or dust contact and charged.In addition, the internal perisporium surface of dust storage chamber 120 is also usually due to the friction with sucking gas or charged with contacting of dust.Like this, by making ion and charged dust or the internal perisporium surface collision of dust storage chamber 120, dust or dust storage chamber 120 are removed to electricity.
Suck gas by dust storage chamber 120 inward turnings, transferring dirt separation.Separated the suction gas after dust and flowed to electric blowing machine 110 dust storage chamber 120 is interior.Dispose filter 150 in the downstream of electric blowing machine 110.Suck gas and flow through filter 150 and be cleaned, then the exhaust pathway 107B that flows through, the discharge 100 from exhaust outlet 108 to main body.
The cleaning of using electric dust collector 1 to carry out if be through with, the user is operated operating portion, and the driving of electric blowing machine 110 and the driving of ion generating element 131 are stopped.After the driving of electric blowing machine 110 and ion generating element 131 stops fully, the user takes out dust storage chamber 120 from main body 100, removes the dust be deposited in dust storage chamber 120.
In the process that drives electric blowing machine 110 and ion generating element 131, dust and dust storage chamber 120 have been carried out except electricity.Therefore, when from the interior removing dust of dust storage chamber 120, reduced that the dust caused because of static disperses or dust adheres to and remained in the situation in dust storage chamber 120.Then, the dust storage chamber 120 of removing after dust is arranged in the main body 100 of electric dust collector 1 again.
On the other hand, if be deposited in the dust amount of dust storage chamber 120 inside, constantly increase,, when driving electric blowing machine 110, the pressure in connecting piece 105 raises.If the pressure in connecting piece 105 is higher than the pressure of regulation, non-return valve 137 is closed air entry 136.If air entry 136 is closed, sucks gas and from air entry 136, do not flow into the inside of ion generating chamber 130.Owing to sucking the gas ion generating element 131 of can not flowing through, so be difficult to provide the ion produced by ion generating element 131 from ion generating chamber 130 is interior in air suction way.
Like this, if non-return valve 137 is closed air entry 136, be difficult to provides ion in air suction way, even so, even but now have a large amount of dust to be deposited in dust storage chamber 120, also can keep the attraction of electric dust collector 1.And, when the user wants to regulate the attraction of electric dust collector 1 byer force, can make attraction become enough strong.
As mentioned above, the electric dust collector 1 of the first embodiment comprises: suction inlet member 101 has suction inlet; Electric blowing machine 110, for generation of sucking gas; Air suction way, the 110 guiding air amounts from suction inlet member 101 to electric blowing machine; And ion generating element 131.Be formed with ion discharge mouth 135 in air suction way, for send the ion produced by ion generating element 131 in air suction way.Electric dust collector 1 also comprises spaced walls 140, and this spaced walls 140 is configured in the inside of air suction way, in order to cover the upstream that sucks the ion discharge mouth 135 on gas flow direction.
Send the ion produced by ion generating element 131 in from ion discharge mouth 135 to air suction way.The ion be sent in air suction way is directed to electric blowing machine 110 together with suction gas.The spaced walls 140 that the upstream of ion discharge mouth 135 is configured in the inside of air suction way covers.Therefore, the dust be included in the suction gas in the air suction way of flowing through is difficult to the 131 1 sides refluences from ion discharge mouth 135 to ion generating element.Like this, by preventing dust, with ion generating element 131, contact, can prevent that the dust plug ion from sending mouth 135 or ion generating element 131 is dirty, can prevent that thus ion generating element is difficult to produce ion.
Thereby can provide a kind of and can be effectively dust or the member that forms air suction way be removed to electric electric dust collector 1.
In addition, the electric dust collector 1 of the first embodiment has dust storage chamber 120, and this dust storage chamber 120 is configured in air suction way, makes to suck gas rotating and carrys out dirt separation.Dust storage chamber 120 is configured in the downstream that sucks the ion discharge mouth 135 on gas flow direction.
In making to suck the dust storage chamber 120 that gas rotating carrys out dirt separation, easily produce the friction, the friction between dust, suction gas and the friction of dust storage chamber 120 and the friction of dust and dust storage chamber 120 that suck gas and dust, thus easily make dust and dust storage chamber 120 charged.Therefore, by dust storage chamber 120 being configured in to the downstream that sucks the ion discharge mouth 135 on gas flow direction, can be used for the ion of sending to air suction way from ion discharge mouth 135 dust storage chamber 120 is removed to electricity.
In addition, in the electric dust collector 1 of the first embodiment, the downstream end of spaced walls 140 is configured to more rely on downstream than the downstream end that sucks the ion discharge mouth 135 on gas flow direction.
Be configured to more rely on downstream than the downstream end that sucks the ion discharge mouth 135 on gas flow direction by the downstream end spaced walls 140, thereby make to be spaced apart wall 140 coverings from the downstream end of swimming over to of ion discharge mouth 135.Thus, can more effectively prevent that ion discharge mouth 135 from being stopped up by dust or ion generating element 131 is dirty.
In addition, as mentioned above, the electric dust collector 1 of the first embodiment comprises: suction inlet member 101 has for sucking the suction inlet of gas and dust; Ion generating chamber 130, have the air entry 136 for sucking gas; Electric blowing machine 110, for generation of sucking gas; Air suction way, suck gas from suction inlet member 101 and ion generating chamber 130 to electric blowing machine 110 guiding; And ion generating element 131, be configured in the inside of ion generating chamber 130.
Be formed with ion discharge mouth 135 at air suction way, for send the ion produced by ion generating element 131 in air suction way.The electric dust collector 1 of the first embodiment also comprises non-return valve 137, and this non-return valve 137 is configured on air entry 136, in order to can make air entry 136 open or close.The pressure of non-return valve 137 based in air suction way, can make air entry 136 open or close.
Be formed with two peristomes on electric dust collector 1, that is, and the air entry 136 of the suction inlet of suction inlet member 101 and ion generating chamber 130.Therefore, can suck the gas that includes dust from the suction inlet of the first suction inlet member, from the air entry of the second suction inlet member, suck the gas that comprises hardly dust.Thus, due to the air that includes dust is not contacted with the ion generating unit that is configured in the second suction inlet component inside, institute is so that the ion generating unit is not easy dirty.
On the other hand, due to the air entry 136 of the suction inlet that is formed with suction inlet member 101 and ion generating chamber 130, so compare with the electric dust collector 1 that there is no air entry 136, even the output of electric blowing machine 110 is identical, attraction also can reduce sometimes.While usually using, the reduction of this attraction does not have problems.But, in the situation that the pressure rise in air suction way is to a certain extent, owing to being formed with ion discharge mouth 135 in ion generating chamber 130, so compare attraction sometimes with electric dust collector in the past, can reduce.
Therefore, configuration non-return valve 137 on air entry 136, for example, when the pressure of the pressure ratio regulation in air suction way is low, non-return valve 137 is opened, and ion is provided in air suction way from ion discharge mouth 135.In addition, when the pressure of pressure ratio in air suction way regulation is high, non-return valve 137 is closed, and provides ion in not from ion discharge mouth 135 to air suction way, thereby preferentially keeps attraction.
In addition, in the situation that the attraction of electric dust collector 1 can be regulated by the user, when the user is adjusted to the attraction of electric dust collector 1 than the attraction of regulation when strong, non-return valve 137 is closed air entry 136 or ion discharge mouth 135, thereby can make attraction enough strong.On the other hand, when the user is adjusted to the attraction of electric dust collector 1 when lower than the attraction of regulation, non-return valve 137 is opened air entry 136 or ion discharge mouth 135, thereby can provide ion fully in air suction way.
Like this, due to the pressure based in air suction way, utilize non-return valve 137 can make air entry 136 open or close, thus can keep the attraction of electric dust collector 1, and can in air suction way, provide ion.
In addition, in the electric dust collector 1 of the first embodiment, non-return valve 137 is configured on air entry 136, in order to can make air entry 136 open or close.
If non-return valve 137 is configured on ion discharge mouth 135,, when sending the ion produced by ion generating element 131 from ion discharge mouth 135, ion and non-return valve 137 collide and ion are disappeared sometimes.Therefore, by non-return valve 137 not being configured on ion discharge mouth 135, but be configured on air entry 136, can prevent that ion and non-return valve 137 from colliding and ion is disappeared.The ion concentration that thus, can prevent from sucking in gas reduces.
