In the electrostatic atomization device, it is desired to further shorten the time until the continuous generation of such mist.

In addition, in order to generate mist efficiently, it is necessary to improve the cooling efficiency of a Peltier element and to ensure moisture condensation. For example, in the case of the electrostatic atomization device disposed inside the cleaner body, it is conceivable to use the exhaust of the electric blower for cooling the Peltier element, but the exhaust of the electric blower is the inside of the electric blower while cooling the electric motor that generates heat. After passing through and including an arrangement from an electric motor, it is not suitable for cooling, and a heat sink or the like may disturb the flow of the exhaust gas and the air flow rate may be lowered.

According to the present invention, by passing a current through a thermoelectric element, the condensation member covering the heat absorbing side of the thermoelectric element is cooled to condensate moisture on the condensation member, and the condensation of the condensed moisture condenses and confronts the condensation member. Since it adheres to, the moisture adhered to the tip side of the electrode can be sprayed directly without, for example, sucking up the moisture from the base end side of the electrode to the tip side.

In addition, it is possible to provide an electric cleaner capable of efficiently cooling the heat dissipation side of the thermoelectric element while reducing the influence on the flow velocity of air generated by the driving of the electric blower.

The insertion through part 122 is a part penetrated by the insertion through part 108 of the second case 87. Therefore, this insertion penetration part 122 is located in the lower part of the water supply sheet 93.

The supply part 123 is a part clamped between the electrically conductive sheet 94 and the 1st case 86, and the water | moisture content sucked up by the absorption part 121 is the electrically conductive sheet 94 through the insertion through part 122. FIG. It is configured to carry.

The conductive sheet 94 is formed of a member having absorptivity and water retention, and is formed on the back side of the electrode holding portion 92, that is, the partial absorbing electrode 91a and the absorbing electrode 91b (particularly the absorbing electrode 91b). It is in close contact with the proximal end side of and electrically connected with the proximal end side of these electrodes 91a and 91b.

In addition, the protrusion 94a of the conductive sheet 94 is inserted through the lead-out opening 125 formed in the upper portion of the first case 86 to protrude out of the case body 89, and the protrusion 94a. ) A DC power supply (not shown) for generating a negative voltage of, for example, -10 to -4 kV, preferably about -6 kV, from a commercial AC power supply that supplies power to the electric blower 51 (FIG. 9) or the like. Is electrically connected to.

Accordingly, the conductive sheet 94 is fed to the electrodes 91a and 91b from the proximal end side by the voltage from the DC power supply unit, so that these electrodes 91a and 91b (the electrode portion 91) are negative (-). It is configured to charge with.

The Peltier element 95 is a heat exchanger that converts electrical energy into thermal energy and has a heat absorbing side surface 95a serving as the heat absorbing side and a heat radiating side surface 95b serving as the heat radiating side.

The lead wires 95c and 95d of the Peltier element 95 are inserted into the lead-out holes 127 and 128 formed in the upper portion of the third case 88 and electrically connected to a power source or the like not shown. For example, temperature control is enabled by controlling the electric current by the control means 52 (FIG. 9).

Moreover, this Peltier element 95 is provided in the installation opening part 111 of the 3rd case 88 so that the heat absorption side surface 95a may face the 2nd case 87 side.

The heat transfer plate 96 is formed in a rectangular flat plate shape larger than the heat absorbing side surface 95a of the Peltier element 95 by a member such as a metal having excellent heat transfer properties such as aluminum, and the heat absorption of the Peltier element 95. It is fixed to the side surface 95a by a heat dissipating silicone, such as a heat dissipating member, and is thermally connected to the heat absorbing side surface 95a.

In addition, the heat transfer plate 96 is substantially flat with the main surface of the second case 87 side of the third case 88 in a state of being fitted to the holding step 113 of the third case 88. It is.

The insulating sheet 97 is formed in the shape of a rectangular thin film layer larger than the installation opening 111, and in contact with the heat absorbing side surface 95a of the Peltier element 95, here, the heat transfer plate 96, and the heat transfer plate ( 96 is attached to the main surface of the second case 87 side of the third case 88.

That is, this insulating sheet 97 is arrange | positioned so that it may be cooled by the heat absorption of the Peltier element 95, and the moisture absorption side surface 95a or the heat absorbing plate 96 is prevented from directly condensing moisture, or the heat absorption side surface 95a or the like. Condensation of moisture and repeated drying of the heat transfer plate 96 are prevented from being corroded or damaged, that is, the Peltier element 95 and the heat transfer plate 96 are protected from water.

In this state, the outer edge portion of the insulating sheet 97 is located outward from the installation opening 111.

In addition, the insulating sheet 97 is water-repellent for increasing the height of water droplets to be condensed at least on the surface 97a serving as the condensation surface on the opposite side to the heat transfer plate 96 (Peltier element 95). The moisture condensation on the surface 97a of the insulating sheet 97 is reliably agglomerated even in a small amount, and is configured to be efficiently supplied to the front ends of the electrodes 91a and 91b.

On the surface 97a of the insulating sheet 97, in a state where the discharge unit U1 and the condensation unit U2 are fixed to each other, the front end sides of the electrodes 91a and 91b have a predetermined minute gap with a window portion. While facing the 121a, the water supply sheet 93 at a position around the position where the electrodes 91a and 91b face each other, that is, outside the installation opening 111, in other words, around the heat transfer plate 96. Absorber 121 is pressed against surface 97a of insulating sheet 97.

Here, the predetermined minute gap at the front end side of the surface 97a of the insulating sheet 97 and the electrodes 91a and 91b is a droplet formed by condensation of moisture condensed on the surface 97a of the insulating sheet 97. The tip ends of the electrodes 91a and 91b are in contact with each other (about 0.5 mm) to increase the efficiency of electric field concentration at the tip ends of the electrodes 91a and 91b and atomize moisture more efficiently. It is formed for.

In addition, this predetermined minute gap is formed by the condensation of water droplets condensed on the surface 97a of the insulating sheet 97 in contact with the instantaneous sides of the electrodes 91a and 91b, thereby providing the respective electrodes 91a, The heat conduction to the insulating sheet 97 (heat transfer plate 96, Peltier element 95) side from the 91b side is interrupted, and the surface 97a of the insulating sheet 97 is kept at a low temperature to prevent loss during condensation. Thus, the Peltier device 95 has a function of preventing a decrease in cooling capacity.

The heat dissipation plate 98 is formed of a member such as a metal having excellent heat transfer properties such as aluminum, and is fixed to the heat dissipation side surface 95b of the Peltier element 95 with silicon for heat dissipation which is a heat dissipation member. It is thermally connected to the heat radiation side surface 95b.

Although the heat sink 98 can use arbitrary shapes and materials as long as it has predetermined thermal characteristics, it has several fin 98a which protrudes to the opposite side with respect to the Peltier element 95. As shown in FIG.

These fins 98a are arranged so as to be spaced apart from each other at substantially equal intervals and arranged in a lattice shape, for example, so as to be exposed to air in the blower chamber 39 (the circulation air passage 45).

As described above, in the electrostatic atomization device 53, the heat absorbing side surface 95a of the Peltier element 95, the insulating sheet 97 and the absorbing portion 121 of the water supply sheet 93 each have an angle with respect to the horizontal direction. In this state, in this embodiment, it arrange | positions on the protrusion part 68 of the 3rd ventilation flow path 43 so that it may follow the vertical direction, and makes the moisture condensed on the surface 97a of the insulating sheet 97 grow larger. This moisture is reliably absorbed into the absorbing portion 121.

That is, the 2nd case 87 and the 3rd case 88 are locked by the 1st case 86 in a vertical shape, respectively.

Next, the operation of the first embodiment will be described.

In the control means 52 shown in FIG. 9, for example, a normal cleaning mode used for cleaning the surface to be cleaned and a vibration damping mode for cleaning the primary filter 31 and the secondary filter 32 are set. have.

In addition, the vibration damping mode is, for example, performed immediately after the end of the cleaning mode, but for example, the configuration performed immediately before the start of the cleaning mode, the configuration performed immediately before the start of the cleaning mode and immediately after the end of the cleaning mode, or the cleaning operation is performed. You may comprise so that it may be made at arbitrary timings, such as a structure performed when it interrupts more than predetermined time.

In the cleaning mode, for example, the control means 52 is first prepared as a ready-to-feed state from a commercial AC power source connected through a power cord (not shown) or a secondary battery built into the main body case 25. Each of the first on-off valve 61, the second on-off valve 63, and the third on-off valve 65 is maintained in an open valve state, and the fourth on-off valve 76, the fifth on-off valve 78, and 6 Maintain each of the on / off valves 81 in the closed valve state.

In this state, the control means 52 drives the electric blower 51 in the operation mode desired by the operator input via the setting button 22 shown in FIG. 10, and the Peltier element shown in FIG. A predetermined current flows through 95 to control the temperature of the Peltier element 95.

The Peltier element 95 absorbs heat from the heat absorbing side surface 95a and radiates heat from the heat radiating side surface 95b according to the current flowing therethrough. In this heat dissipation side surface 95b, heat dissipation is promoted by heat dissipation into the blower chamber 39 (FIG. 9) through the heat dissipation plate 98 thermally connected to this heat dissipation side surface 95b. Therefore, the Peltier element 95 It absorbs efficiently from the endothermic side surface 95a, and produces a rapid temperature difference with respect to outside temperature.

At this time, the heat transfer plate 96 thermally connected to the heat absorbing side surface 95a of the Peltier element 95 is cooled to a temperature substantially equal to the heat absorbing side surface 95a, and the insulating sheet 97 covering the heat transfer plate 96 is also formed. Likewise cooled.

Therefore, moisture contained in the air in the blower chamber 39 (FIG. 9) which entered the case body 89 condenses on the surface 97a of the insulating sheet 97 which has water repellency.

And the worker grips the holding part 21 shown in FIG. 10, and moves the floor brush 19 etc. on the surface to be cleaned, and inhales dust with air.

At this time, the air containing the dust is moved into the main body case 25 from the main body suction port 47 after moving the pipe part 12 from the front end side to the proximal end side. And as shown in FIG. 9, it reaches the dust collecting chamber 34 through the 1st opening / closing valve 61 which is opened first, and is continued by the primary filter 31 with comparatively large dust, ie, big dust and air. Are separated. As a result, large dust separated is collected in the dust collecting chamber 34.

In addition, the air introduced into the first intake chamber 35 through the primary filter 31 flows into the second intake chamber 36 through the second open / close valve 63, and the secondary filter ( 32) it is separated into relatively small dust, that is, fine dust and air.

For this reason, fine dust is captured by the surface 32a of the upstream of the secondary filter 32, and the air which passed through this secondary filter 32 and flowed into the 3rd intake chamber 37 is opened | released, It is sucked from the inlet port 83 to the electric blower 51 via the third open / close valve 65, which is located therein, and also through the intake cylinder portion 71.

The exhaust flowed out from the exhaust port 84 of the electric blower 51 to the blower chamber 39 is discharged to the outside of the main body case 25 (cleaner main body 13) through the main body exhaust port 48. In addition, the said air flow is shown by the solid line A1 in FIG.

On the other hand, in the vibration damping mode, when the operator operates the predetermined setting button 22 in order to finish cleaning, the control means 52 first prepares the first opening / closing valve 61 and the second opening / closing valve 63. ) And the third open / close valve 65 are maintained in the closed valve state, and the fourth open / close valve 76, the fifth open / close valve 78, and the sixth open / close valve 81 are held in the open valve state. .

After that, the control means 52 inputs an electric current to the conductive sheet 94 of the electrostatic atomizer 53 (with the electrostatic atomizer 53 turned on) to drive the electric blower 51. Control is performed. The input of the electric blower 51 in this case is set lower than the maximum input provided to the electric blower 51 in a cleaning mode, for example.

Here, in the electrostatic atomization apparatus 53, as shown in FIG. 1, the water condensation condensed on the surface 97a of the insulating sheet 97, and the water droplet W in which this condensed water grows is insulated. It is attached to the front end side of each of the absorbing electrode portions 117 and the absorbent electrodes 91b of the partially absorbing electrodes 91a facing each other with a gap on the surface 97a of the sheet 97.

Since the high voltage negative voltage is applied to these electrode portions 91 through the conductive sheet 94, respectively, the electric field is provided at the front end sides of the absorbing electrode portion 117 and the absorbing electrode 91b of the partially absorbing electrode 91a. Concentration occurs and natural discharge occurs.

On the tip side of the absorbing electrode portion 117 of the partially absorbing electrode 91a and the absorbing electrode 91b, the pico size to the nano size is caused by an electrical action exceeding the surface tension of water directly attached by surface tension and capillary action. Invisible mist M (FIG. 9) occurs (about 500 pm to 5,000 pm), which immediately splits and scatters.

After the mist M is generated as a transient phenomenon when the condensed water droplets W are attached to the front end sides of the absorbing electrode portions 117 and the absorbent electrodes 91b of the respective partial absorbent electrodes 91a, The partial absorbent electrode 91a and the absorbent electrode 91b increase in water content rate (the ratio of the absorbed amount of water to the absorbable amount (volume of the absorbing electrode portion 117 or the absorbent electrode 91b)) over time, and the predetermined rate is increased. Continuous generation (continuous atomization) of the mist M is started when it becomes more than the water content rate of.

That is, the mist M is sequentially generated sequentially from each partial absorbent electrode 91a having a relatively small volume of the absorbing electrode portion 117, and thereafter, the mist M is continuously generated from each absorbent electrode 91b. It becomes.

In the case where the amount of moisture aggregated on the surface 97a of the insulating sheet 97 is relatively large, part of the water is supplied from the surface 97a of the insulating sheet 97 as indicated by arrow X1 in FIG. 8. It is absorbed by the absorbing part 121 of the sheet 93, and is conveyed from the absorbing part 121 to the conductive sheet 94 through the insertion through part 122 and the supply part 123 as shown by arrow X2, It is sucked up by the conductive sheet 94 and conveyed to the base end side of each absorbent electrode 91b.

This water is sucked up to the tip side with the capillary phenomenon over time by each absorbent electrode 91b, and atomized, and it becomes the mist M (FIG. 9) and scatters.

In other words, even water that is excessively condensed on the surface 97a of the insulating sheet 97 is effectively used without being leaked by the water supply sheet 93. In addition, when transporting the water absorbed by the absorbent portion 121 of the water supply sheet 93 to the proximal end side of the absorbent electrode 91b, the absorbent portion 121 is supplied to the supply portion 123 via the insertion through portion 122. As it is transported, the supply path is long and takes time when transporting moisture.

However, since the water supply sheet 93 has high repair performance, water is reliably transported to the electrode absorbent electrode 91b, and water leakage is prevented even when a large amount of moisture condenses on the surface 97a of the insulating sheet 97. The width of use environment and continuous use time become wider.

At this time, when the absorbent electrode 91b is disposed at the lowermost portion (position closest to the insertion through portion 122) of the electrode portion 91, the water supply time through the water supply sheet 93 and the conductive sheet 94 is shortened. .

And the mist M scattered is discharged | emitted in the air in the circulation airflow path 45 which passes through the inside of the case body 89 shown in FIG. 9 through the opening part 101,102.

In addition, with the driving of the electric blower 51, the intake negative pressure is increased in the intake cylinder portion 71, the opening 73, the fourth intake chamber 38, the second air vent 42, and the first intake chamber. By sequentially acting on the dust collecting chamber 34, the first ventilating air passage 41, the second intake chamber 36, and the third ventilating air passage 43, from the exhaust port 84 of the electric blower 51. Exhaust from the blower chamber 39 flows into the second intake chamber 36 through the third ventilating air passage 43.

As a result, as indicated by broken line A2 in FIG. 9, the exhaust of the electric blower 51 circulates to the dust collecting chamber 34 side through the circulating air passage 45, so that the mist M passes through the circulating air passage 45 and the dust collecting chamber. (34), the first intake chamber 35, the second ventilating air passage 42, the fourth intake chamber 38 and every corner to reach the intake cylinder portion 71 is to be scattered.

The fine mist M containing the OH radicals generated by the electrostatic atomization device 53 is supplied to the exhaust gas circulated as described above, so that the mist M is the secondary filter 32 during the circulation process. Does not pass in the thickness direction, it flows from the upper side to the lower side along the surface 32a of the upstream side (upstream side in the cleaning mode) of the secondary filter 32, and further passes through the first ventilating air passage 41. Through the dust collecting chamber 34 is introduced.

At this time, the exhaust of the electric blower 51 blows on the surface 32a on the upstream side of the secondary filter 32, and blows the fine dust collected on the surface 32a downward.

Moreover, the control means 52 drives the vibration damping means 75, vibrates the secondary filter 32, and collects the fine dust collected by this secondary filter 32 to this secondary filter 32. Remove from)

At this time, since fine dust is not sucked into the secondary filter 32 by the flow of exhaust gas circulating, it is easily removed by the drive of the damping means 75. The removed fine dust floats in the second intake chamber 36, and the mist M acts on the suspended fine dust.

In addition, the circulating exhaust gas passes through the second ventilating air passage 42 from the dust collecting chamber 34, thereby bypassing the secondary filter 32 and openings of the fourth intake chamber 38 and the intake cylinder portion 71. It is sucked into the intake port 83 of the electric blower 51 via 73, and does not pass the secondary filter 32 in the thickness direction.

In other words, the intake negative pressure of the electric blower 51 acts from the rear side (downstream side) with respect to the secondary filter 32, and fine dust is applied to the surface 32a on the upstream side of the secondary filter 32. Do not inhale.

For this reason, the secondary filter 32 is easily damped by the damping means 75, and the removed fine dust moves to the dust collecting chamber 34 by the flow of the exhaust gas passing through the second intake chamber 36. do.

As described above, the static dust (fine dust) removed from the secondary filter 32 and moved to the dust collecting chamber 34 and the large dust collected in the dust collecting chamber 34 are generated by the electrostatic atomizer 53. Since the OH radical contained in the mist M acts repeatedly, it is possible to increase the chance of contact between the mist M and the dust, so that decomposition of various germs, that is, sterilization (sterilization) and deodorization, can be effectively performed.

In particular, since dust (fine dust) collected on the upstream side 32a of the secondary filter 32 is blown away by exhaust gas circulating in the circulation air passage 45, the mist M acts on the dust. Becomes higher, so that decomposition of various bacteria, that is, sterilization (sterilization) and deodorization, is performed more effectively.

In addition, these bactericidal action and deodorant action are also imparted to the secondary filter 32 itself.

The control means 52 stops the vibration damping means 75 when it is determined that a predetermined time, for example, about 10 seconds has elapsed since the start of the vibration damping mode. In the stage immediately after the cleaning completion of the vibration suppression mode, the fine dust collected in the secondary filter 32 has not yet solidified and is not brought into a state having strong adhesive force, so it is collected in the secondary filter 32. Fine dust can be removed sufficiently.

In addition, when the control means 52 determines that the predetermined time, for example, about 20 to 30 seconds has elapsed since the start of the vibration suppression mode, the conductive sheet 94 and the Peltier element (of the electrostatic atomizer 53) The feeding to 95 and the feeding to the electric blower 51 are stopped, respectively, to end the vibration suppression mode.

As described above, in the first embodiment, the electrode portion 91 includes the partial absorbing electrode 91a having the absorbing electrode portion 117 on the front end side of the electrode body 116 having no absorbency. In these partially absorptive electrodes 91a, the absorbable amount with respect to the amount of dew condensation water droplets can be relatively reduced than the absorbent electrode 91b or the like (the water content of the same amount of absorption can be relatively increased).

Therefore, in these partially absorptive electrodes 91a, since the water content rate becomes relatively high, the time required until reaching the predetermined water content rate at which continuous atomization occurs can be shortened, so that the start time of continuous atomization is reduced. It can be shortened.

In addition, since the electrode main body 116 and the absorbing electrode portion 117 have a plurality of types of electrodes having different volume ratios (for example, partially absorbing electrodes 91a1 and 91a2 and absorbing electrodes 91b), they are collected by environmental conditions. Even when the moisture is relatively low, the water content increases rapidly as the volume ratio of the absorbing electrode portion 117 is relatively small (for example, the partial absorbing electrode 91a1), so that continuous atomization can be started immediately. Can be.

When the amount of moisture collected is relatively high, the volume of the absorbing electrode portion 117 is relatively larger (e.g., the partial absorbing electrode 91a2 and the absorbing electrode 91b). It can absorb sufficiently, and can spray water effectively.

Therefore, it is possible to reliably cope even under various environmental conditions (for example, environmental conditions in which the humidity is significantly different (high fluctuation range)).

In addition, in the said 1st Embodiment, the detail of the circulation air passage 45 etc. is not limited to the said structure.

That is, in the normal cleaning mode, intake air is sucked through the dust collecting chamber 34, and in the dust removing mode, each air intake chamber is constructed so that exhaust of the electric blower 51 can be circulated to the dust collecting chamber 34. The arrangement | positioning, number, etc. of each ventilation flow path, each open / close valve, etc. can be set arbitrarily.

Next, 2nd Embodiment of this invention is described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

In the electrostatic atomization device 53 of the second embodiment, the air cooling fan 129 is provided at the distal end of the fin 98a of the heat sink 98 according to the above embodiments.

This air cooling fan 129 is electrically connected to a power supply or the like not shown, and the driving is controlled by the control means 52, for example.

And the air cooling fan 129 forcibly sends air between the fins 98a of the heat sink 98, thereby promoting heat radiation at the heat sink 98, that is, heat radiation at the heat radiation side 95b of the Peltier element 95. Thus, the Peltier element 95 is temperature controlled more efficiently.

That is, since the air can be cooled more efficiently and quickly at the heat absorbing side surface 95a of the Peltier element 95, moisture can be condensed on the surface 97a of the insulating sheet 97 more efficiently and quickly.

Moreover, in each said embodiment, like the 3rd Embodiment of this invention shown in FIG. 12, the front end part of the electrode main body 116 of each partial absorptive electrode 91a, and the base end part of the absorption electrode part 117, respectively It is good also as a structure which is formed in planar shape, these are adhesively fixed by electrically conductive adhesive etc., and are connected electrically.

Next, 4th Embodiment is described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

In this fourth embodiment, the vacuum cleaner 11 in which the electrostatic atomization device 53 of the first embodiment is disposed is a cyclone type vacuum cleaner instead of the circulation type.

Inside the main body case 25 of the vacuum cleaner main body 13, the cyclone separation apparatus 125 which is a dust collecting apparatus as a dust collection part detachably installed in the dust collecting chamber 34, and the downstream side of this cyclone separation apparatus 125 A first ventilating air passage 126, which is a ventilating air passage communicating with the intake port 83 of the electric blower 51 in the blower chamber 39 from the upper side, is formed.

The cyclone separation device 125 has a substantially bottomed cylindrical dust collector main body 132 that partitions the dust storage chamber 131 therein, and the front end side of the dust collector main body 132 has a front end side. The intake opening 133 which communicates with the suction port 47 and communicates with the dust accommodation chamber 131 at the rear end side protrudes and is formed.

Moreover, the 2nd ventilation air path 134 which is the external air blowing air path communicated with the 1st ventilation air path 126 is formed in the rear part of the dust collector main body 132, and protrudes.

In the dust accommodating chamber 131, a cylindrical cyclone separator 136 is provided for separating dust by turning air including dust sucked in from the intake opening 133 along its outer periphery.

An opening 137 is formed in the outer circumference of the cyclone separator 136, and the opening 137 is provided with a primary filter 138 as first dust separating means. Moreover, the secondary filter 139 as a 2nd dust separation means is provided in the upper end part of the dust storage chamber 131 (dust collection part main body 132).

The primary filter 138 separates dust in the air including dust, for example, by filtration.

In addition, the secondary filter 139 functions as a final filter. That is, this secondary filter 139 can collect dust (fine dust) which could not be collected by the primary filter 138.

The second ventilating air passage 134 communicates with the inside of the dust storage chamber 131 through an on-off valve 141 of normally closed, such as a solenoid valve, as an opening and closing means. The second ventilating passage 134 has an opening formed in the lower part of the outer vent 142 for introducing outside air, and here, air in the dust collecting chamber 34 into the second ventilating passage 134.

The second ventilating air passage 134 communicates with the first ventilating air passage 126 via the communication opening 144, and the electrostatic atomization device 53 is provided by closing the communication opening 144. .

Here, in the electrostatic atomization device 53, the outer edge portion of the third case 88 is fitted without gaps in the communication opening 144 so as to insert the heat sink 98 into the first ventilating air passage 126, and the discharge portion The unit U1 side is arrange | positioned so that it may be located in the 2nd ventilation air path 134. As shown in FIG.

On the other hand, the part of the 1st ventilation air path 126 may be formed in the inside of the cover 55, for example.

Next, the operation of the fourth embodiment will be described.

In the cleaning mode, the control means 52 firstly prepares an opening / closing valve in a state in which power can be supplied from a commercial AC power source connected through a power cord (not shown) or a secondary battery built into the main body case 25. Keep 141 in a closed valve state.

In this state, the control means 52 drives the electric blower 51 in the operation mode desired by the operator input via the setting button 22, and flows a predetermined electric current through the Peltier element 95, The element 95 is temperature controlled.

In addition, when the air sucked into the electric blower 51 passes through the heat sink 98 when passing through the first ventilating air passage 126, effective heat dissipation in the heat sink 98 is enabled. As a result, the water contained in the air which entered the case body 89 condenses on the surface 97a of the insulating sheet 97 which has water repellency.

And the worker grasps the holding part 21, moves the bottom brush 19 etc. on the surface to be cleaned, and inhales dust with air.

At this time, air containing dust is sucked into the main body case 25 from the main body suction port 47 after moving the pipe part 12 from the front end side to the proximal end side.

And the air containing a dust flows in along the inner peripheral surface of the dust collector main body 132 from the intake opening 133 to the dust storage chamber 131 inside the dust collector main body 132, and therefore, of the cyclone separation part 136 It turns around and separates by comparatively large dust, ie, big dust and air, by centrifugal force. As a result, the separated large dust is dropped and accommodated in the dust storage chamber 131.

In addition, the air passing through the primary filter 138 is further separated into a relatively small dust, that is, fine dust and air by passing through the secondary filter 139. For this reason, fine dust is trapped by the secondary filter 139, and the air which passed this secondary filter 139 passes from the inlet port 83 to the electric blower 51 via the 1st communication air path 126. Is inhaled.

Exhaust exhausted from the exhaust port 84 of the electric blower 51 to the blower chamber 39 is discharged to the outside of the main body case 25 (the vacuum cleaner main body 13) through the main body exhaust port 48. In addition, the said air flow is shown by the solid line A3 in FIG.

On the other hand, in the vibration damping mode, when the operator operates the predetermined setting button 22 in order to finish cleaning, the control means 52 firstly maintains the on / off valve 141 in the open valve state in preparation.

After that, the control means 52 inputs an electric current to the conductive sheet 94 of the electrostatic atomizer 53 (with the electrostatic atomizer 53 turned on) to drive the electric blower 51. Control is performed. The input of the electric blower 51 in this case is set lower than the maximum input provided to the electric blower 51 in a cleaning mode, for example.

Here, the electrostatic spraying apparatus 53 immediately splits and scatters the invisible mist M of pico size to nano size (about 500 pm to 5,000 pm) by the same action as the first embodiment. Let's do it. The scattered mist M is discharged into the air in the second ventilating air passage 134 through the openings 101 and 102.

In addition, with the driving of the electric blower 51, the intake negative pressure acts sequentially on the first ventilating air passage 126, the dust storage chamber 131, the second ventilating air passage 134, and the outer vent 142. As a result, outside air flows into the second ventilating air passage 134 from the outer vent 142.

As a result, as shown by the broken line A4 in the figure, air is sucked into the outer vent 142, the second ventilated air passage 134, the dust storage chamber 131, and the first ventilated air passage 126, and thus the electrostatic atomization apparatus ( The mist M generated from 53 is scattered to every corner reaching the second ventilating air passage 134, the dust storage chamber 131, and the first ventilating air passage 126.

As described above, since the fine mist M containing the OH radicals generated by the electrostatic atomization device 53 is supplied to the intake air, the mist M is located in the cyclone separation device 34. While acting on the dust collected in the dust storage chamber 131 of 125, each filter 138, 139 passes in the thickness direction, respectively, and it acts on the dust collected by these filters 138, 139, respectively.

As a result, various bacteria are decomposed, that is, sterilization (sterilization) and deodorization are performed. These bactericidal actions and deodorant actions are also given to the filters 138 and 139 themselves.

And if the control means 52 judges that predetermined time, for example, about 20 second-30 second has passed from the start time of the damping mode, the conductive sheet 94 and the Peltier element 95 of the electrostatic atomizer 53 ) And the electric power feeding to the electric blower 51 are stopped, respectively, to end the vibration suppression mode.

As described above, in the fourth embodiment, the effect similar to that of the first embodiment can be obtained by arranging the electrostatic atomization device 53 of the first embodiment in the air path in the vibration damping mode.

As described above, in each of the above-described embodiments, by flowing a current through the Peltier element 95, the insulation sheet 97 covering the heat transfer plate 96 on the heat absorbing side of the Peltier element 95 is cooled to form the insulation sheet. Moisture condensation is formed on the surface 97a of the 97, and the condensed moisture is agglomerated to absorb the electrode portion 117 and each of the partial absorbent electrodes 91a facing the surface 97a of the insulating sheet 97. Since it adheres to the front end side of each of the absorbent electrodes 91b, the water absorbed from at least the front end side is absorbed at least from the front end side of each partial absorbent electrode 91a and the proximal end of the absorbent electrode 91b. It is possible to atomize immediately by the natural discharge from the front end side of the 91a and the absorbent electrode 91b.

That is, in each of the above embodiments, water can be directly adhered to and absorbed from the front end side to each of the partial absorbent electrodes 91a and the absorbent electrode 91b which atomize the water at the front end side. After that (after driving the electrostatic atomization apparatus 53), the time until the mist M is scattered can be shortened, that is, it is possible to almost eliminate the time difference between the dew condensation phenomenon and the atomization phenomenon, and the effect is excellent. .

That is, in the case of the vacuum cleaner 11, since it is common to store dust in the dust collecting chamber 34 until a certain amount is collected, it is easy to generate | occur | produce germs and odors in this dust, but the said electrospray atomizer 53 Since the dust can be sterilized and deodorized, the odor can be suppressed even when dust is stored in the dust collecting chamber 34 for a long time or when a large amount of dust is stored in the dust collecting chamber 34.

In particular, since the vacuum cleaner 11 generally has a relatively short driving (energization) time, by using the electrostatic atomizer 53, it is possible to reliably (continuously) spray moisture condensed even during a short driving time. Since it can be made, the ease of use becomes favorable.

In addition, since moisture in the circulation air passage 45, in other words, moisture in the air is aggregated and supplied to each of the partial absorbent electrodes 91a and the absorbent electrodes 91b, the vacuum cleaner 11 can be used without selecting a place. , Also does not need watering.

That is, since it can be set as the structure of water supply free (maintenance-free), the labor which a worker etc. supply water can be abbreviate | omitted, and the ease of use becomes favorable, for example, the use range expands.

In addition, in each said embodiment, you may make constant the volume ratio of the electrode main body 116 of each partial absorptive electrode 91a, and the absorption electrode part 117 in all the partially absorptive electrodes 91a.

The front end side of each absorbent electrode 91 may be in contact with the insulating sheet 97 to face each other.

In addition, as long as the heat absorbing side of the Peltier element 95, the insulating sheet 97, and the water absorbing portion 121 of the water supply sheet 93 have an angle with respect to the horizontal direction, it is not necessary to arrange them in a vertical shape.

In addition, for example, in the case of the electric cleaner 11 which inclines or oscillates when the cleaner main body 13 uses, etc., the heat absorption side of the Peltier element 95 and the insulating sheet 97 in at least one state under a use state. ) And the absorbent portion 121 of the water supply sheet 93 can have an effect similar to those of the above-described embodiments when the absorbent portion 121 has an angle with respect to the horizontal direction.

Next, the assembly method of 5th Embodiment of the said invention is demonstrated.

When assembling the electrostatic atomization device 411, after assembling the condensation unit 415 and the discharge unit 416 separately, the intermediate case 431 of the condensation unit 415 is discharged from the upper case 418. The lower case 455 of the unit 416 is attached to each other to support the upper and lower sides.

First, as shown in FIGS. 16 to 18, the dew condensation unit 415 is thermally connected to the heat absorbing side 445a of the Peltier element 445 with respect to the intermediate case 431. These heat transfer plates 446 and Peltier elements 445 are adhesively fixed.

At this time, the heat transfer plate 446 is fitted to the exposed opening portion 436 of the intermediate case 431, and the lower surface thereof is substantially flat with the lower surface 435a of the bottom 435 of the intermediate case 431.

In addition, a heat sink 433 is provided on the heat radiation side surface 445b of the Peltier element 445. Then, the tip ends of the lead wires 445d and 445e of the Peltier element 445 are inserted through the notch openings 437 and 437 to protrude to the outside of the intermediate case 431 to be electrically connected to a power supply or the like.

On the other hand, as shown in FIG. 19, the discharge unit 416 first sequentially installs the connection portion 456, the water supply sheet 457, and the conductive sheet 458 with respect to the lower case 455. The electrode 478 is press-fitted to the electrode holding part 479 and the electrode part 459 assembled previously is provided.

Thereafter, the intermediate case 431 is sandwiched from the top and bottom between the upper case 418 connecting the air path nozzle 422 to the upper case main body 421, and the lower case 455, and is attached to the screw 463. The upper case 418 and the lower case 455 are connected to each other in the vertical direction.

At this time, the front end side of each electrode 478 faces the heat absorbing side (heat transfer plate 446 (surface 453a of insulating sheet 453)) of Peltier element 445 at a predetermined distance. In addition, as shown in FIG. 14, the lower end portion of the communication air passage 426 of the upper case 418 is hermetically connected to the air distribution unit 468 so that the branch air passage 498 is partitioned, and the upper case 418. The upper portion of the outside air suction unit 467 is blocked by the blocking unit 469.

Moreover, by connecting the nozzle connection part 466 of the lower case 455 and the connection part 494 of the exhaust nozzle 460 which assembled the discharge part 490 and the nozzle cover part 491 previously, FIG. The discharge air passage 499 shown in FIG.

The inlet port 472 of the branch air passage 498 is connected to the low speed flow path portion 346b of the air passage portion 322 shown in FIG. 15, and the outlet 429 of the branch air passage 498 is connected to the air passage portion ( 322 is in communication with the high speed flow path 346a.

As a result, the branch air passage 498 is connected to the suction air passage 350, and the outside air inlet 497 of the exhaust nozzle 460 and the exhaust side of the electric blower 321 are connected to each other by the connecting member 339. In addition, the connection portion 456 of the discharge unit 416 is electrically connected to the high voltage power supply portion 476 by the lead wire 477.

In addition, the outside air suction port 470 of the discharge air passage 499 is hermetically connected to the outside of the exhaust air passage 340, for example, the outside of the cleaner main body 413 (main body case 312).

In this state, since the electrostatic atomization device 411 is located in the exhaust air passage 340, the exhaust port 495 of the exhaust air passage 499 and the exhaust opening 496 of the exhaust nozzle 460 are exhausted, respectively. It communicates with the air path 340.

That is, the discharge air path 499 is connected to the outside air and the exhaust air path 340.

Next, the operation of the fifth embodiment will be described.

At the time of cleaning, the user grasps the holding part 307 shown in FIG. 24, for example, by connecting the power cord to an outlet (not shown), such that the power supply can be supplied to the control means 323 and the electric blower 321. FIG. By operating the desired setting button 308, the control means 323 drives the electric motor 327 of the electric blower 321 in the set operation mode. In addition, the control means 323 drives the electrostatic atomizer 411.

As for the electric blower 321, the centrifugal fan 328 rotates by the drive of the electric motor 327, and the suction inlet 331, the cover inlet port 337, and the air path part 322 which are connected to this centrifugal fan 328 in an airtight manner. ), The negative pressure acts on the dust collecting cup 311 through the opening 348 and the communicating portion 314.

Moreover, the connection pipe part 301 of the pipe part 412 (the connection pipe part 301 of the dust collecting cup 311) which is airtightly connected to this main body suction port 351, and communicates with the cup suction port 313 of this dust collecting cup 311, and a hose body. 302, the extension pipe 304, and the bottom brush 305 act | operate, and the dust on the bottom surface which is a to-be-cleaned surface is inhaled with air.

At this time, the electric blower 321 attempts to generate vibration in the radial direction (center axis direction) intersecting in the rotational direction by driving, but the vibration component is expanded and contracted by each coil spring 343 having a substantially horizontal shape. The electric blower 321 is absorbed by centering by this, and transmission of the vibration to the main body case 312 (cover body 333) is suppressed.

And the air containing the suctioned dust is sucked along the tangential direction from the main body suction port 351 through the cup suction port 313 through the pipe part 412 to the inside of the dust collecting cup 311, and of this dust collecting cup 311 By generating the swirl flow which rotates along an inner peripheral surface, the dust contained in air is centrifuged.

The centrifuged dust falls into the dust collecting cup 311 by its own weight and is collected, and the air from which the dust is separated is passed from the opening portion 348 to the guiding portion 346 of the air passage portion 322 through the communication portion 314. Is inhaled.

Thereafter, the air flows downwardly along the guiding section 346 and expands when the air flows into the connecting duct 345 of the duct 322.

Further, the air is sucked into the centrifugal fan 328 through the cover inlet port 337 and the inlet port 331 of the electric blower 321 hermetically connected to the connection air path unit 345 of the air path unit 322.

The air sucked into the centrifugal fan 328 is blown out in the circumferential direction of the centrifugal fan 328, flows into the electric motor 327 while rectifying by the rectifying plate 329, and cools the inside of the electric motor 327. The exhaust port 332 is exhausted to the outside of the electric blower 321.

In addition, the gas is exhausted into the case body portion 316 through the cover exhaust port of the cover body 333, and is exhausted from the body exhaust port to the outside of the body case 312 while cooling the control means 323 and the like.

On the other hand, the electrostatic atomization apparatus 411 controls the electric current which flows into the Peltier element 445 by the control means 323, and the Peltier element 445 is temperature-controlled. The Peltier element 445 absorbs heat from the heat absorbing side surface 445a and radiates heat from the heat radiating side surface 445b according to the current flowing therethrough.

Here, in the branch air passage 498, the pressure in the low speed flow path part 346b is relatively higher than the pressure in the high speed flow path part 346a due to the difference in the flow velocity of the air sucked by the driving of the electric blower 321. Because of the increase, the venturi effect prevents the inlet port 472 communicated with the low speed flow path 346b from the side of the outlet port 429 communicated with the high speed flow path 346a to pass through the electric motor 3127 of the electric blower 321. Does not generate low temperature (cold) airflow.

Since the heat dissipation plate 433 thermally connected to the heat dissipation side surface 445b of the Peltier element 445 is located in the branch air passage 498 in which air flow is generated, the heat dissipation plate 433 radiates heat with the low temperature air flow passing through the branch air passage 498. As a result, heat dissipation is promoted, and heat is absorbed efficiently. Therefore, the Peltier element 445 absorbs heat efficiently from the heat absorbing side surface 445a to generate a rapid temperature difference with respect to the outside air temperature.

The heat transfer plate 446 thermally connected to the heat absorbing side 445a of the Peltier element 445 is cooled to a temperature approximately equal to the heat absorbing side 445a, and the insulating sheet 453 covering the heat transfer plate 446 is similarly applied. Is cooled.

For this reason, the water contained in the air of the discharge | emission air path 499 (internal space part 465) condenses on the surface 453a of the insulating sheet 453 which has water repellency.

Thereafter, the control means 323 energizes the conductive sheet 458 of the electrostatic atomizer 411 through the high voltage power supply unit 476 (the electrostatic atomizer 411 is turned on).

In the electrostatic spraying device 411, water condensation condensed on the surface 453a of the insulating sheet 453, and water droplets on which the condensed water has grown are opposed to each other with a gap on the surface 453a of the insulating sheet 453. Is attached to the tip side of each electrode 478.

Since the high voltage negative voltage is applied to the electrodes 478 through the conductive sheet 458 and the connecting portion 456 from the high voltage power supply 476, electric field concentration occurs on the front end side of the electrode 478. A spontaneous discharge occurs and an eye of pico size to nano size (about 500 pm to 5,000 pm) is caused by an electrical action exceeding the surface tension of moisture directly attached to the tip side of these electrodes 478 by surface tension and capillary action. Invisible mist immediately splits and scatters.

The condensation droplets are attached to the front end side of each electrode 478, and the water content of the electrode 478 (the ratio of water absorbed to the absorbable amount (volume of the electrode 478)) increases over time. Continuous generation of mist (continuous atomization) is started when it becomes more than predetermined water content.

In addition, among the moisture aggregated on the surface 453a of the insulating sheet 453, the ones not attached to the electrode 478 are dropped by gravity and sucked up by the water supply sheet 457 and the conductive sheet 458, It is conveyed to the base end side of the electrode 478.

This moisture is sucked up by the capillary phenomenon to the tip side by the capillary phenomenon, and atomized, and it mists and scatters in the discharge air path 499 by each electrode 478.

That is, the water supply sheet 457 and the conductive sheet 458 are effectively used without water leakage even with water condensed excessively on the surface 453a of the insulating sheet 453.

At this time, the exhaust from the electric blower 321 flows into the discharge cover 499 into the nozzle cover portion 491 of the exhaust nozzle 460 connected through the connecting member 339.

By increasing the flow rate of the flowed air, the air is blown out (arrow B1) into the exhaust air passage 340 upward from the exhaust opening 496 through the vent B located around (near) the discharge port 495. The air in the discharge air passage 499 is blown out from the discharge port 495 to the exhaust air passage 340 by the nebulizer effect (arrow B2).

Accordingly, in the discharge air passage 499, a low-temperature (cold) airflow is generated from the outside air suction port 470 connected to the outside air to the discharge port 495 without passing through the electric motor 327 of the electric blower 321. Mist scattered in the discharge air passage 499 is discharged into the exhaust air passage 340 and is exhausted from the main body exhaust port to the outside of the main body case 312 together with the exhaust from the electric blower 321.

In this way, the exhaust nozzle 460 causes the discharge of mist from the discharge port 495 of the discharge air passage 499.

When the cleaning is finished, the user operates the predetermined setting button 308 to stop the driving of the electric blower 321 and the electrostatic atomizer 411.

According to the fifth embodiment described above, the heat dissipation side 433 which is thermally connected to the heat dissipation side of the Peltier element 445 of the electrostatic atomization device 411, and here to the heat dissipation side of the Peltier element 445, is divided into the branch air passage 498. Placed within).

That is, in the intake air passage 350 formed on the intake side of the electric blower 321 and in communication with the dust collecting cup 311, the branch air passage 498 having the intake port 472 and the outlet port 429 at positions different in flow velocity. ), The effect on the air flow rate generated by the driving of the electric blower 321 without disturbing the flow of air flowing through the intake air passage 350 by the electrostatic atomizer 411 by the Venturi effect Can be efficiently introduced into the branch air passage 498 without using another member such as a cooling fan.

As a result, it is possible to prevent the occurrence of turbulence and noise, the deterioration of the suction performance of the electric blower 321, and the colder airflow that is not affected by the arrangement of the electric motor 327 of the electric blower 321. Since the heat sink 433 in the branch air passage 498 can be cooled, the heat radiating side of the Peltier element 445 can be cooled efficiently.

In addition, in the fifth embodiment, the electrostatic atomization device 411 locates the heat dissipation plate 433 thermally connected to the heat dissipation side of the Peltier element 445 in the branch air passage 498, and the Peltier element 445. If the condensation of water on the heat absorbing side of the c) is misted by the natural discharge from the electrode 478, it can be configured arbitrarily.

In addition, although the heat sink 433 is located in the branch air passage 498, for example, the heat dissipation side surface 445b of the Peltier element 445 may be positioned in the branch air passage 498.
