In this state, the rim of the inlet 135 of the first separating / collecting part 26 is press-contacted with the communication opening sealing member 104 to be hermetically connected to the communication opening 103, The discharge port 154 is brought into pressure contact with the rim of the inflow opening 182e of the second separation and dust collecting section 27 so that the inflow opening 154 and the inflow opening 182e are hermetically connected. The rear end side of the handle portion 152 of the first separation and dust collecting portion 26 is connected to the front end side of the arrangement portion 66 of the main body case 25.

Therefore, the duct portion 12 and the suction side of the electric blower 31 are hermetically connected through the first separating dust collecting portion 26 and the second separating dust collecting portion 27 to form the air passage W. [

The user grasps the gripper 21 and operates the desired setting button 22 while the power supply unit 121 is enabled to feed the power so that the control means controls the phase of the electric blower 31, The electric blower 31 is driven in the operation mode set by the operation of the setting button 22. [

The negative pressure generated by the driving of the electric blower 31 is transmitted to the communication duct portion 115 of the downstream duct portion 39 through the communication hole 63, the second separation dust collection portion 27, the first separation dust collection portion 26, And acts as the tube portion 12 through the communication opening 103, the upstream duct portion 38, and the main body suction port 107. In the tubular portion 12, a negative pressure acts on the hose body 16, the extension pipe 18 and the bottom brush 19, and the dust and dirt are discharged from the tip of the floor brush 19 loaded on the surface to be cleaned Inhale.

The dust air is discharged from the main intake port 107 through the bottom brush 19, the extension pipe 18 and the hose body 16 through the communication opening 103 of the upstream side duct portion 38 to the first separation dust collecting portion 26 Through the inlet 135 into the case body 125 of the main body 100. [ The entrained air introduced from the inlet 135 turns in the circumferential direction between the case body 125 (the case body 131) and the swivel body 161 of the swivel portion 126, and the seizure is centrifuged Falls down gravitationally and is collected at the lower portion of the case body 125 (the case main body 131) of the first separating dust collecting portion 26.

The swirling air circulating in the first separating / collecting part 26 flows into the inside of the swirling part main body 161 from the ventilation opening part 166 through the dust filter 167. Further, when passing through the dust filter 167, fine dust is trapped in the dust filter 167 rather than dust in the dust air. A part of the compressed air circulating in the first separating and collecting section 26 flows toward the compression section 162 and flows into the inside of the swing section main body 161 from the communication opening section 168 through the compression filter 169 do. When the compressed air passes through the compression filter 169, fine dust is gathered in the compression filter 169 and the dust collected in the case body 125 (the case body 131) is compressed And is compressed by the filter 169 to be compressed.

After passing through the connecting air passage 153, the compressed air passed through the swirler main body 161 is discharged from the discharge port 154 and flows from the inflow opening portion 182e to the inflow air passage portion 177 Flows into the rectifying passage 188 of each rectifying section 185 of the second separating dust collecting section 27 and flows into the separating chamber 181 while being rectified by the rectifying passage 188, Lt; / RTI &gt;

The compressed air introduced into these separation chambers 181 flows in a circumferential direction along the inner circumferential surface of these separation chambers 181 at a flow velocity higher than the flow velocity in the case body 125 of the first separation / The fine dust is centrifugally separated from the lower end of each of the separation chambers 181 to the dust collection case 172 via the connection portion 183 and the dust collection case 172 of the dust collection case 172 And is collected in each reservoir 201b. The clean air from which the fine dust has been removed passes through the air flow tube 189 of the rectifying part 185 and is extracted into the outflow air passage part 178 and joined together.

The air that joins the outflow air passage portion 178 flows from the communication passage 63 of the outflow opening portion 194 through the communication air passage portion 115 of the downstream duct portion 39 to the electric blower 31 in the electric blower chamber portion, Passes through the inside of the electric blower 31 and cools the electric blower 31 and is laterally exhausted from an exhaust port located on the front side of the electric blower 31 to be exhausted. The exhaust air flows into the connection air passage portion 117 of the downstream duct portion 39 while passing through the filter 119 and flows into the power source chamber 40 from the connection air passage portion 117, (Not shown). The exhaust air that has passed rearward of the power source chamber 40 is diffused when it flows into the diffusion chamber 41 and flows from each exhaust hole 109 to the outside of the main body case 25 of the cleaner main body 13 And is dispersed and exhausted.

When the cleaning is completed, the control means first operates the ultraviolet lamp 67 to irradiate the ultraviolet light for a predetermined time, and then stops the electric blower 31 and the ultraviolet lamp 67 by operating the setting button 22 by the user. Since the ultraviolet lamp 67 is in a state of being close to the second separation dust collector 27 with only a slight gap, a sufficient sterilization effect can be obtained even if the irradiation time of the ultraviolet ray is very short to several seconds to several tens of seconds 10). The ultraviolet rays irradiated from the ultraviolet lamp 67 pass through the window portion 195 through the opening 68 and the permeable member 195a of the lower portion of the arrangement portion 66, And the inside of the separation chamber 181 is irradiated into the separation chamber 181 through the connection openings 192a to sterilize (sterilize) the inside of the outflow air passage portion 178 Sterilization). A part of the ultraviolet light irradiated into the separation chamber 181 located in the central column L1 is radiated into the dust collection case body 201 of the dust collection case 172 through the separation chamber 181 in the axial direction (Sterilized) sterilization (fine dust) stored in the dust-collecting case main body 201 and the storage portion 201b of the dust-collecting case main body 201.

When a predetermined amount or more of dirt is stored in the dust collecting case 172 of the first separating dust collecting portion 26 and the second separating dust collecting portion 27, the user presses the first separating dust collecting portion 26 and the second separating dust collecting portion 27 Can be removed from the main body case 25, respectively, and the dust can be discarded.

As described above, according to the first embodiment, the first separating dust collecting portion 26 and the second separating dust collecting portion 27, which circulate dust air sucked by the driving of the electric blower 31 to centrifugally collect dust, And the ultraviolet rays are irradiated from the ultraviolet lamp 67 to the second separate dust collecting section 27 located on the downstream side, whereby the germs can be effectively removed by the ultraviolet rays.

That is, since the compressed air introduced into the second separating / collecting unit 27 is centrifuged by the first separating / collecting unit 26, no seizure is stored in the second separating / collecting unit 27. Therefore, when ultraviolet rays are irradiated from the ultraviolet lamp 67 to the second separation and dust collecting unit 27, the ultraviolet rays are not blocked or diffused by squeezing, so that the germs can be effectively removed by ultraviolet rays.

Particularly, since the seizure is mainly collected in the first separating dust collecting portion 26, the user frequently carries out maintenance such as removing the first separating dust collecting portion 26 from the main body case 25 and discarding the dust inside, It is difficult for the dust to accumulate in the inside over a long period of time, and reproduction of germs and the like is relatively small. On the other hand, since the second separating dust collecting section 27 is located at the rear end of the first separating dust collecting section 26 from which most of the dust is removed, dust (seizure) is hardly stored and maintenance such as disposal of dust is not performed frequently , Germs and the like tend to propagate more than the first separating dust collecting part (26). That is, in the dust collecting means 28, the amount of dust collected at the rear end (downstream side) is small, frequent maintenance is not required, and dust and dirt tend to be stored over a long period of time. Therefore, the second separating / collecting section 27 located on the downstream side is sterilized (sterilized) by irradiating ultraviolet rays, thereby making it difficult for the collecting means 28 to reproduce the whole germs.

The ultraviolet lamp 67 is configured to emit ultraviolet rays to the separation chamber 181 of the second separation and collection section 27 and the outflow air passage section 178 through which the dust separated by the separation chamber 181 passes, It is possible to sterilize (sterilize) the humidified air just before the dust is centrifugally separated by the separation chamber 181 and the air after the dust has been centrifuged by the separation chamber 181, Can be effectively removed. Particularly, the air passing through the outflow air passage portion 178 is not sucked into the electric blower 31 after being sucked into the electric blower 31 because there is no point where the germs are likely to occur on the downstream side thereof. It is possible to more reliably prevent the odorous odor from occurring in the exhaust from the electric blower 31 due to the sterilization of air.

In the first embodiment, the timing of turning on the ultraviolet lamp 67 can be arbitrarily set.

Further, the dust collecting means 28 may be provided with three or more multi-stage centrifugal separators. In this case, the ultraviolet lamp 67 is configured to emit ultraviolet light to at least one of at least one centrifugal portion excluding the most upstream centrifugal portion, that is, a centrifugal separator located on the downstream side, The same operational effects as those of the embodiment can be exhibited.

Next, a second embodiment will be described with reference to Figs. 11 and 12. Fig. The same components and operations as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

The second embodiment differs from the first embodiment in that the electric blower 31 is controlled by a control means such as a microcomputer (not shown) housed in the main body 32 in accordance with the setting operation of the setting button 22 211 are controlled to be on-off or the like.

The ultraviolet lamp 67 is for sterilizing (sterilizing) a part of the air passage W, in this embodiment, the second separating dust collecting section 27 by irradiating ultraviolet rays. For example, The lighting state including the light-off is controlled.

Next, the internal structure of the second embodiment will be described.

The control means 211 is configured so that an operation signal from the setting button 22 is inputted. The control means 211 is operable by being supplied with power from a power supply unit 121 to which a plug portion 121a at the front end is connected to a commercial AC power supply e which is a power supply. Is configured to set the input of the electric blower 31 in accordance with the operation signal from the setting button 22 through the operation button Tr.

The control means 211 is electrically connected to a timer T serving as time measuring means and an ultraviolet lamp 67 so that the operation of the ultraviolet lamp 67 can be controlled. The timing for the control means 211 to operate the ultraviolet lamps 67 is the same as the timing for operating the ultraviolet lamps 67 in the present embodiment except that the setting button 22 is operated while the electric blower 31 is operating, And is configured to operate the ultraviolet lamp 67 immediately before stopping the electric blower 31 and for a first predetermined time T1 over which the time T is measured via the timer T. [ It is preferable that the first predetermined time T1 is set variable, for example, in accordance with the operating time of the electric blower 31, that is, the length of time from the start to the stop of the electric blower 31 of the present cycle. In setting the first predetermined time T1, for example, a predetermined number or a plurality of threshold values are compared with the operating time of the electric blower 31, and the operation time is compared with the operation time The first predetermined time T1 may be calculated and set by a predetermined formula using the operating time of the electric blower 31 as a variable. It is considered that dust collecting case 172 of dust collecting case 172 of second separating dust collecting section 27 stores much dust as the operating time of electric blower 31 is longer. Therefore, as the operating time of electric blower 31 becomes longer, It is preferable to set the predetermined time T1 to be long.

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

In cleaning, the user grasps the gripping portion 21 in a state in which the plug portion 121a is connected to the commercial AC power supply e and power is supplied by the power supply portion 121, The control means 211 fed from the power source unit 121 controls the phase angle of the electric blower 31 through the control element Tr so that the electric blower 31 is operated in the operation mode set by the operation of the setting button 22. [ 31 and the dust and air are sucked together with the air from the front end of the floor brush 19 loaded on the surface to be cleaned by the negative pressure generated by the drive of the electric blower 31. [ The process of separating and collecting each dust from the dust air is the same as that in the first embodiment, and the description is omitted.

When the cleaning is completed, the user operates the setting button 22 so that the control means 211 operates the ultraviolet lamp 67 first to irradiate ultraviolet rays, and then the electric blower 31 and the ultraviolet lamp 67 Stop. That is, during the operation of the electric blower 31, the control means 211 determines whether or not the stop operation has been performed by the setting button 22, that is, whether the electric blower 31 is turned off (Step 1) If it is determined in step 1 that OFF is not set, step 1 is repeated. If it is determined that OFF is set, the control means 211 activates the timer T and simultaneously turns on the ultraviolet lamp 67 (Step 2). Thereafter, the control means 211 judges whether or not the first predetermined time T1 has elapsed from the timing at which the electric blower 31 is turned off, that is, the ultraviolet lamp 67 is turned on (Step 3) The control means 211 judges whether the timer T and the ultraviolet lamp 67 have been operated or not when the first predetermined time T1 has elapsed, (Step 4). The timer T may be reset at the same time as this stop, or may be reset immediately before the start in step 2. The timing of stopping the motor-driven blower 31 may be set to a time immediately before the start of the ultraviolet lamp 67 and the timer T (immediately after it is determined that the off is set in step 1), the ultraviolet lamp 67 and the timer T of the ultraviolet lamps 67 and the timer T simultaneously with the start of the ultraviolet lamps 67 and the timers T during the start of the ultraviolet lamps 67 and the timers T, Or after stopping the operation of the microcomputer.

The ultraviolet rays irradiated from the ultraviolet lamp 67 pass through the window portion 195 through the lower opening 68 and the transmitting member 195a of the arrangement portion 66 and are guided to the outflow air passage portion 178 to sterilize the inside of the outflow air passage portion 178 and irradiate into the respective separation chambers 181 through the respective connection openings 192a to sterilize the inside of these separation chambers 181, do. A part of the ultraviolet light irradiated into the separation chamber 181 is radiated to the dust collection case 172 through the separation chamber 181 in the axial direction and the inside of the dust collection case 172 and the inside of the dust collection case 172 (Sterilization) of stored sejin (fine dust).

When a predetermined amount or more of dirt is stored in the dust collecting case 172 of the first separating dust collecting portion 26 and the second separating dust collecting portion 27, the user presses the first separating dust collecting portion 26 and the second separating dust collecting portion 27 Can be removed from the main body case 25, respectively, and the dust can be discarded.

As described above, according to the second embodiment, the control means 211 controls the setting button 22 to change the timing of turning off the motor-driven blower 31 from the set timing to the first predetermined time (Sterilizing) the inside of the air passage W, in this embodiment, by irradiating ultraviolet rays to the inside of the air passage W, in this embodiment, the second separating dust collecting section 27 by operating the first lamp T1 and the ultraviolet lamp 67, The ultraviolet rays emitted from the ultraviolet lamp 67 are stronger than those for generating the redox action of the photocatalyst, and the ultraviolet rays emitted from the ultraviolet lamp 67 are stronger than those for generating the redox action of the photocatalyst, (Sterilization) light having a sterilization effect, it is possible to sterilize (sterilize) in a short time. Therefore, the power saving of the electric vacuum cleaner 11 becomes possible.

It is also assumed that the electric blower 31 increases the collecting amount of the dust in the second separating dust collecting portion 27 as the operation is performed for a long time and the amount of germs in the air passage W (the second separating dust collecting portion 27) The first predetermined time T1 for operating the ultraviolet lamp 67 is changed in accordance with the operation time of the immediately preceding electric blower 31. More specifically, the longer the operation time of the electric blower 31 is, The air passage W (the second separation and collection section 27) can be sterilized more effectively (sterilization) by setting the predetermined time T1 longer.

Next, a third embodiment will be described with reference to Fig. The same components and operations as those of the second embodiment are denoted by the same reference numerals, and a description thereof will be omitted.

The third embodiment differs from the second embodiment in that the control means 211 controls the timing at which the ultraviolet lamp 67 can be fed from the commercial AC power source e to the electric blower 31 And operates the plug 121a for a predetermined time T2 from the timing (plug-in) connected to the commercial AC power supply e.

The control means 211 controls the setting of the electric blower 31 by the setting button 22 before the predetermined time T2 elapses from the above timing at which the plug portion 121a is connected to the commercial AC power supply e When ON is set, the ultraviolet lamp 67 is continuously operated even during operation of the motor-driven blower 31. That is, regardless of whether or not the operation for starting the motor-driven blower 31 has been performed, the control means 211 determines that the predetermined time T2 has elapsed from the above timing at which the plug portion 121a is connected to the commercial AC power supply e The ultraviolet lamp 67 continues to operate until it elapses.

13, the control means 211 determines whether or not the plug portion 121a is connected to the commercial AC power source e (whether it is plugged in) (Step 11). If it is determined in step 11 that the plug portion 121a is not connected to the commercial AC power supply e (plugged in), the step 11 is repeated. When it is determined in step 11 that the plug part 121a is connected (plugged in) to the commercial AC power source e, the control means 211 activates the timer T and at the same time activates the ultraviolet lamp 67 (Step 12).

Subsequently, the control means 211 determines whether or not a predetermined time T2 has elapsed from the timing at which the plug portion 121a is connected to the commercial AC power supply e, that is, the ultraviolet lamp 67 is turned on 13). The control unit 211 stops the timer T and the ultraviolet lamp 67 (step 14), and when the predetermined time T2 has elapsed That is, whether or not the electric blower 31 is turned on (step 15). If it is determined in step 15 that ON is not set, step 15 is repeated. If it is determined that ON is set, the electric blower 31 is started in the operation mode set by the setting button 22 Step 16).

On the other hand, if it is determined in step 13 that the predetermined time T2 has not elapsed, the control unit 211 determines whether or not the start operation, that is, whether the electric blower 31 is turned on by the setting button 22 (Step 17). If it is determined in step 17 that ON is not set, the process returns to step 13. If it is determined that ON is set, the electric blower 31 is started in the operation mode set by the setting button 22 Step 18).

After this step 18, the control means 211 judges whether or not a predetermined time T2 has elapsed from the timing at which the plug portion 121a is connected to the commercial AC power supply e, that is, the ultraviolet lamp 67 is turned on (Step 19). When it is determined that the predetermined time T2 has not elapsed, Step 19 is repeated. If it is determined that the predetermined time T2 has elapsed, the timer T and the ultraviolet lamp 67 are stopped (Step 20). When the setting button 22 is set to the OFF state of the electric blower 31 before the elapse of the predetermined time T2 in step 19, the control means 211 controls the operation of the ultraviolet lamp 67, for example, And the electric blower 31 may be immediately stopped together with the ultraviolet lamp 67 after the elapse of the predetermined time T2 at the timing when the plug portion 121a is connected to the commercial AC power supply e Or after the electric blower 31 is stopped and the ultraviolet lamp 67 is turned on until the predetermined time T2 elapses from the timing at which the plug portion 121a is connected to the commercial AC power supply e May be continued. The timer T may be reset at the same time as the stop of step 14 or step 20, or may be reset immediately before the start of step 12.

According to the third embodiment described above, the control means 211 controls the electric blower 31 so that the timing at which electric power can be supplied from the commercial AC power source e, that is, the plug portion 121a is connected to the commercial AC power source e The sterilizing (sterilizing) the ultraviolet ray lamp 67 by operating the ultraviolet ray lamp 67 for a predetermined time T2 by irradiating the air passage W and the second separating dust collecting section 27 in this embodiment with ultraviolet rays, The ultraviolet rays emitted from the ultraviolet lamp 67 are stronger than those for generating the redox effect of the photocatalyst, and the destruction of DNA such as germs and the like (Sterilization) light having a sterilization effect, it is possible to sterilize (sterilize) in a short time. Therefore, the power saving of the electric vacuum cleaner 11 becomes possible.

In addition, for example, in the case where the period from the last cleaning to the current cleaning is open, it is considered that the bacteria are proliferating in the inside of the air passage W (the second separation / collection unit 27) It is possible to reliably prevent the generation of an unusual smell in the exhaust gas at the time of starting the electric blower 31 by disinfecting (sterilizing) by the ultraviolet lamp 67 before the start of the electric blower 31, that is, before the electric blower 31 is started .

When the electric blower 31 is turned on by the setting button 22 before the predetermined time T2 elapses from the timing at which the plug portion 121a is connected to the commercial AC power supply e, It is possible to prevent the problem that the electric blower 31 is not started even though the setting button 22 is being operated by operating the ultraviolet lamp 67 continuously during the operation of the air blower 31 (The second separation / collection unit 27) can be reliably sterilized (sterilized).

The second and third embodiments may be combined. That is, the control of the third embodiment may be performed prior to the start of the electric vacuum cleaner 11, and the control of the second embodiment may be performed when the electric vacuum cleaner 11 is stopped during driving. At this time, for example, in the step 19 of the third embodiment, when the setting of the electric blower 31 is set to OFF by the setting button 22 before the second predetermined time T2, which is the predetermined time, The timer 211 may reset the timer T, for example, and proceed to step 2 of the second embodiment.

According to at least one of the second and third embodiments, the first separating dust collecting part 26 and the second separating dust collecting part 26, which rotate dust air sucked by the driving of the electric blower 31 to centrifugally collect dust, It is possible to efficiently remove germs by ultraviolet rays by connecting the separation dust collecting section 27 in multiple stages and irradiating ultraviolet rays from the ultraviolet lamp 67 to the second separation dust collecting section 27 located on the downstream side.

That is, since the compressed air introduced into the second separating dust collecting section 27 is centrifuged by the first separating dust collecting section 26, the dust is not stored in the second separating dust collecting section 27. Therefore, when ultraviolet rays are irradiated from the ultraviolet lamp 67 to the second separation / dust collecting unit 27, the ultraviolet rays are not blocked or diffused by the germination, so that the germs can be effectively removed by ultraviolet rays.

Particularly, since the dust is mainly collected in the first separating dust collecting part 26, the user frequently carries out maintenance such as removing the dust from the inside of the case 25 from the first separating dust collecting part 26, It is difficult for the dust to accumulate in the inside over a long period of time, and reproduction of germs and the like is relatively small. On the other hand, since the second separating dust collecting section 27 is located at the rear end of the first separating dust collecting section 26 from which most of the dust is removed, dust (seizure) is hardly stored and maintenance such as disposal of dust is not performed frequently , Germs and the like tend to propagate more than the first separating dust collecting part (26). That is, in the dust collecting means 28, the amount of dust collected at the rear end (downstream side) is small, so frequent maintenance is not required, and dust and dirt tend to be stored over a long period of time. Therefore, the second separating / collecting section 27 located on the downstream side is sterilized (sterilized) by irradiating ultraviolet rays, thereby making it difficult for the collecting means 28 to reproduce the whole germs.

The ultraviolet lamp 67 is configured to emit ultraviolet rays to the separation chamber 181 of the second separation and collection section 27 and the outflow air passage section 178 through which the dust separated by the separation chamber 181 passes, It is possible to sterilize (sterilize) the humidified air just before the dust is centrifugally separated by the separation chamber 181 and the air after the dust has been centrifuged by the separation chamber 181, Can be effectively removed. Particularly, the air passing through the outflow air passage portion 178 is not sucked into the electric blower 31 after being sucked into the electric blower 31, It is possible to more reliably prevent the odorous odor from occurring in the exhaust from the electric blower 31 due to the sterilization of air.

In the second and third embodiments, the first separating dust collecting section 26 and the second separating dust collecting section 27 may have any structure as long as dust can be collected from the dust air.

The ultraviolet lamp 67 may be configured to emit ultraviolet light to an arbitrary portion of the air passage W. [

In each of the above-described embodiments, the second separation and dust collecting section 27 is formed by plated with a portion where ultraviolet rays are irradiated so as not to be deteriorated by the ultraviolet ray irradiated from the ultraviolet lamp 67 Or a member other than synthetic resin, which is not deteriorated by ultraviolet rays (hardly deteriorates), may be used.

The electric vacuum cleaner 11 is not limited to the canister type but may be an upright type cleaner body 13 having a bottom brush 19 connected to the lower portion of the cleaner main body 13 having a length in the vertical direction, A handy type in which the floor brush 19 and the like are directly connected to clean the vacuum cleaner main body 13 while transporting the vacuum cleaner main body 13 or a robot type in which the cleaner main body 13 frequently or autonomously runs by a drive wheel Can be used.

In addition, although a few embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention.
