In addition, a plurality of plate-like partition portions 201a are provided in the front-rear direction along the left-right width direction inside the dust collection case body 201, and a plurality of partition portions 201a are provided inside the dust collection case body 201 by the partition portions 201a. The reservoir 201b is partitioned in the front-rear direction. These partition portions 201a are hermetically connected to the lower ends of the connecting portions 183, so that the respective reservoir portions 201b communicate with the separation chambers 181 adjacent in the left-right width direction. Further, the dust collection case body 201 is located on the lower end side of each separation chamber 181 in the central row L1, in other words, on the opposite side of the rectification unit 185 (introduction opening) with respect to the separation chamber 181. Then, it is located directly under the separation chamber 181 in the central row L1, that is, on the extension of the central axis of the cylinder passing portion 189 of the separation chamber 181 in the central row L1. Therefore, the dust collection case body 201 is located on the opposite side of the window 195 (ultraviolet lamp 67) through the separation chamber 181.

Further, the receiving portion 203 is a portion that supports the lower end portion of the connecting portion 183, and the lower end portion of the connecting portion 183 is airtightly connected.

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

At the time of cleaning, the first separated dust collecting part 26 and the second separated dust collecting part 27 are previously attached to the main body case 25 of the cleaner body 13 respectively.

When attaching the second separated dust collecting portion 27, the second separated dust collecting portion 27 is fixed to the main body case 25 by the second attaching / detaching mechanism by inserting and pushing the second separated dust collecting portion 27 into the mounting recess 44 from the front of the main body portion 32. In this state, the edge of the outflow opening 194, which is the downstream end of the outflow air passage portion 178, is pressed against the communication port seal member 64 and is hermetically connected to the communication port 63, and the window 195 (transmission member 195a) Is opposed to the ultraviolet lamp 67 through a slight gap.

Further, when attaching the first separated dust collecting portion 26, the front lower portion of the lid body 132 is placed on the protruding portion 33 while the handle portion 152 is gripped, and is rotated rearward around the front lower portion. . Then, the first separated dust collecting part 26 is fixed to the main body case 25 by the first attaching / detaching mechanism while being positioned in the left-right width direction with respect to the main body case 25. In this state, the edge portion of the inlet 135 of the first separation dust collecting portion 26 is pressed against the communication opening seal member 104 and hermetically connected to the communication opening 103, and the discharge port seal member 155 of the discharge port 154 is The discharge port 154 and the inflow opening 182e are hermetically connected by being pressed against the edge of the inflow opening 182e of the second separated dust collecting portion 27. Further, the rear end side of the handle portion 152 of the first separated dust collecting portion 26 is connected to the front end side of the arrangement portion 66 of the main body case 25.

Therefore, the air passage W is formed by airtightly connecting the pipe portion 12 and the suction side of the electric blower 31 via the first separated dust collecting portion 26 and the second separated dust collecting portion 27.

Then, in a state where power can be supplied by the power supply unit 121, the user operates the desired setting button 22 by holding the holding unit 21, so that the control unit controls the phase angle of the electric blower 31, and the setting button 22 The electric blower 31 is driven in the operation mode set by the operation.

The negative pressure generated by the driving of the electric blower 31 is the communication air passage portion 115, the communication port 63, the second separation dust collection portion 27, the first separation dust collection portion 26, the communication opening 103, the upstream side of the downstream duct portion 39. It acts on the pipe part 12 through the duct part 38 and the main body suction port 107. In the pipe portion 12, negative pressure acts on the hose body 16, the extension pipe 18, and the floor brush 19, and dust is sucked together with air from the tip of the floor brush 19 placed on the surface to be cleaned.

The dust-containing air passes through the floor brush 19, the extension pipe 18, and the hose body 16, and passes through the communication opening 103 of the upstream duct portion 38 from the main body suction port 107 to the inside of the case body 125 of the first separation dust collection portion 26. Through the inlet 135. The dust-containing air flowing in from the inlet 135 swirls in the circumferential direction between the case body 125 (case body 131) and the swivel part body 161 of the swivel part 126, and the coarse dust is centrifuged and gravity is lowered. It falls and is collected in the lower part of the case body 125 (case body 131) of the first separated dust collection unit 26.

The dust-containing air swirling in the first separation dust collecting portion 26 flows from the ventilation opening 166 into the swirling portion main body 161 through the dust collecting filter 167. When passing through the dust collection filter 167, dust finer than coarse dust in the dust-containing air is collected by the dust collection filter 167. Part of the dust-containing air swirling in the first separated dust collecting section 26 flows toward the compression section 162 and flows into the swiveling section main body 161 from the communication opening 168 via the compression filter 169. . When passing through the compression filter 169, dust finer than coarse dust in the dust-containing air is collected in the compression filter 169 and also collected in the case body 125 (case body 131). Dust is pressed against the compression filter 169 and compressed.

The dust-containing air that has passed through the inside of the swivel unit body 161 (air containing fine dust) passes through the connection air passage 153, is then discharged from the discharge port 154, and flows into the inflow air passage portion 177 from the inflow opening 182e. Then, the air flows into the rectifying passage portions 188 of the respective rectifying portions 185 of the second separation dust collecting portion 27 from the introduction opening and flows into the separation chambers 181 while being rectified by the rectifying passage portions 188.

The dust-containing air that has flowed into the separation chamber 181 swirls in the circumferential direction along the inner peripheral surface of the separation chamber 181 at a flow velocity greater than the swirling flow velocity in the case body 125 of the first separation dust collection unit 26. Then, fine dust (fine dust) is centrifuged and gravity falls from the lower end of each separation chamber 181 to the dust collecting case 172 via the connecting portion 183, and the dust collecting case main body 201 of the dust collecting case 172 It is collected in each reservoir 201b. The clear air from which fine dust (fine dust) has been removed passes through the cylinder 189 of the rectifying unit 185, is extracted to the outflow air passage unit 178, and merges with each other.

The air merged into the outflow air passage 178 is sucked from the outflow opening 194 through the communication port 63 into the electric blower 31 in the electric blower chamber from the communication air passage 115 of the downstream duct 39. After passing through the blower 31 and cooling the electric blower 31, it is exhausted from the exhaust port located on the front side of the electric blower 31 to the side to become exhaust air. The exhaust air flows through the filter 119 and flows into the connection air passage portion 117 of the downstream duct portion 39, and flows from the connection air passage portion 117 into the power supply chamber 40. The power supply unit 121 is cooled. The exhaust air that has passed through the power supply chamber 40 to the rear is diffused when flowing into the diffusion chamber 41, and is distributed and exhausted from the exhaust holes 109 to the outside of the main body case 25 of the cleaner body 13.

When the cleaning is completed, the user operates the setting button 22 so that the control unit first operates the ultraviolet lamp 67 to irradiate ultraviolet rays for a predetermined time, and then stops the electric blower 31 and the ultraviolet lamp 67. Since the ultraviolet lamp 67 is in close proximity to the second separated dust collecting part 27 through only a small gap, the ultraviolet irradiation time is about several seconds to several tens of seconds. A fungus (bactericidal) effect can be obtained (FIG. 10). Then, the ultraviolet rays irradiated from the ultraviolet lamp 67 pass through the window portion 195 through the opening 68 below the arrangement portion 66 and the transmission member 195a, and are irradiated to the outflow air passage portion 178 in the second separated dust collection portion 27. The inside of the outflow air passage portion 178 is sterilized (sterilized) and irradiated into each separation chamber 181 through each connection opening 192a to sterilize (sterilize) the inside of the separation chamber 181. Further, a part of the ultraviolet light irradiated into the separation chamber 181 located in the central row L1 passes through the separation chamber 181 in the axial direction and is irradiated into the dust collection case body 201 of the dust collection case 172. Fine dust (fine dust) stored in the dust case main body 201 and in the reservoir 201b of the dust collection case main body 201 is sterilized (sterilized).

When a predetermined amount or more of dust has accumulated in the dust collecting case 172 of the first separated dust collecting unit 26 and the second separated dust collecting unit 27, the user can use the first separated dust collecting unit 26 and the second separated dust collecting unit 172. The dust portions 27 can be removed from the main body case 25 to discard dust.

As described above, according to the first embodiment, the first separated dust collecting unit 26 and the second separated dust collecting unit that rotate the dust-containing air sucked by the driving of the electric blower 31 to collect the dust by centrifugal separation. By connecting the unit 27 in multiple stages and irradiating the second separated dust collecting unit 27 located on the downstream side with ultraviolet rays from the ultraviolet lamp 67, germs can be effectively removed by ultraviolet rays.

That is, since the dust-containing air flowing into the second separated dust collecting portion 27 is obtained by centrifuging coarse dust by the first separated dust collecting portion 26, the second separated dust collecting portion 27 accumulates coarse dust. There is nothing. Therefore, when the second separation dust collecting unit 27 is irradiated with ultraviolet rays from the ultraviolet lamp 67, the ultraviolet rays are not blocked or diffused by the coarse dust, so that germs can be effectively removed by the ultraviolet rays.

Particularly, since coarse dust is mainly collected in the first separated dust collecting portion 26, the user frequently removes the first separated dust collecting portion 26 from the main body case 25 and discards the dust inside. Since maintenance is performed, it is difficult for dust to accumulate inside for a long period of time, and propagation of germs and the like is relatively small. On the other hand, the second separated dust collecting portion 27 is located at the rear stage of the first separated dust collecting portion 26 from which most of the dust has been removed, so that dust (fine dust) is difficult to collect and maintenance such as dust disposal is performed. However, various germs and the like are more likely to propagate than the first separated dust collection unit 26. That is, in the dust collecting means 28, the amount of dust collected in the latter stage (downstream side) is small, and frequent maintenance is not required, and the dust tends to be accumulated over a long period of time. Therefore, by irradiating the second separated dust collecting portion 27 located on the downstream side with ultraviolet rays for sterilization (sterilization), it is possible for the dust collection means 28 as a whole to hardly propagate bacteria.

Further, the ultraviolet lamp 67 irradiates the separation chamber 181 of the second separation dust collecting portion 27 and the outflow air passage portion 178 through which the air separated from the dust is passed by the separation chamber 181 with ultraviolet rays. Each of the dust-containing air immediately before the dust is centrifuged by the separation chamber 181 and the air after the dust is centrifuged by each separation chamber 181 can be sterilized (sterilized), so that germs can be removed more effectively. . In particular, the air passing through the outflow air passage portion 178 has no place where germs are likely to be generated downstream, and is sucked into the electric blower 31 and then exhausted. By sterilizing (sterilizing), it is possible to more reliably prevent the generation of a strange odor in the exhaust from the electric blower 31.

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

Furthermore, the dust collecting means 28 may be configured to include a multi-stage centrifuge of three or more stages. In this case, the ultraviolet lamp 67 is configured to irradiate at least one of the centrifugal separation units excluding the most upstream centrifugal separation unit, that is, at least one of the centrifugal separation units located on the downstream side. The same operational effects as those of the first embodiment can be obtained.

Next, a second embodiment will be described with reference to FIGS. 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 second embodiment, in the first embodiment, the electric blower 31 is turned on / off by the control means 211 such as a microcomputer housed in the main body 32 in accordance with the setting operation of the setting button 22. Are controlled.

Further, the ultraviolet lamp 67 sterilizes (sterilizes) a part of the air passage W by irradiating ultraviolet rays onto the second separated dust collecting portion 27 in this embodiment, and is turned off by the control means 211, for example. The lighting state including is controlled.

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

The control means 211 is configured such that an operation signal from the setting button 22 is input. Further, the control means 211 can be operated by receiving power from a power supply unit 121 in which a plug unit 121a at the tip is connected to a commercial AC power source e that is a power source, for example, via a control element Tr such as a triac, The input of the electric blower 31 is set according to the operation signal from the setting button 22.

Further, the control means 211 is electrically connected to a timer T as a time measuring means and an ultraviolet lamp 67, and the operation of the ultraviolet lamp 67 can be controlled. In this embodiment, the timing at which the control unit 211 operates the ultraviolet lamp 67 is immediately before the setting unit 22 is operated and the control unit 211 stops the electric blower 31 while the electric blower 31 is operating. Yes, the ultraviolet lamp 67 is operated for a first predetermined time T1 measured via a timer T. The first predetermined time T1 is preferably variably set in accordance with, for example, the operation time of the electric blower 31, that is, the length of time from the start to the stop of the electric blower 31 this time. When the first predetermined time T1 is set, for example, a preset threshold value or threshold values are compared with the operating time of the electric blower 31 and set in advance corresponding to the magnitude relationship between the operating time and the threshold value. The first predetermined time T1 may be calculated and set by a predetermined mathematical formula using the operation time of the electric blower 31 as a variable. In any case, the longer the operating time of the electric blower 31 is, the more dust is accumulated in the dust collecting case 172 of the second separated dust collecting unit 27. 1 It is preferable to set the predetermined time T1 long.

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

When cleaning, the user can operate the desired setting button 22 by holding the grip portion 21 in a state in which the plug portion 121a is connected to the commercial AC power source e and power can be supplied by the power source portion 121. The control means 211 fed from the power supply unit 121 controls the phase angle of the electric blower 31 via the control element Tr, drives the electric blower 31 in the operation mode set by the operation of the setting button 22, Due to the negative pressure generated by the drive, dust is sucked together with air from the tip of the floor brush 19 placed on the surface to be cleaned. Since the process of separating and collecting each dust from the dust-containing air is the same as that in the first embodiment, description thereof is omitted.

When the cleaning is completed, the user operates the setting button 22 so that the control unit 211 first operates the ultraviolet lamp 67 to irradiate ultraviolet rays, and then stops the electric blower 31 and the ultraviolet lamp 67. That is, during the operation of the electric blower 31, the control means 211 determines whether or not a stop operation has been performed by the setting button 22, that is, whether or not the electric blower 31 has been set off (step 1). Step 1 is repeated when it is determined that is not set, and when it is determined that OFF is set, the control means 211 starts the timer T and lights (starts) the ultraviolet lamp 67 (Step 2). . Thereafter, the control means 211 determines the timing at which the electric blower 31 is set to OFF, that is, whether or not the first predetermined time T1 has elapsed from the lighting of the ultraviolet lamp 67 (step 3). If it is determined that the time has not elapsed, step 3 is repeated. If it is determined that the first predetermined time T1 has elapsed, the control unit 211 stops the timer T and the ultraviolet lamp 67 (step 4). Note that the timer T may be reset at the same time as this stop, or may be reset immediately before starting in step 2. The timing of stopping the electric blower 31 is, for example, immediately before the start of the ultraviolet lamp 67 and the timer T (immediately after it is determined that OFF is set in step 1), simultaneously with the start of the ultraviolet lamp 67 and the timer T, the ultraviolet lamp 67 During the operation of the timer T, it is possible to set an arbitrary timing such as when the ultraviolet lamp 67 and the timer T are stopped or after the ultraviolet lamp 67 and the timer T are stopped.

The ultraviolet rays emitted from the ultraviolet lamp 67 pass through the window portion 195 through the opening 68 and the transmission member 195a below the arrangement portion 66, and are emitted to the outflow air passage portion 178 in the second separated dust collecting portion 27. The inside of the outflow air passage portion 178 is sterilized (sterilized) and irradiated into each separation chamber 181 through each connection opening 192a to sterilize (sterilize) the inside of the separation chamber 181. Further, a part of the ultraviolet light irradiated in the separation chamber 181 passes through the separation chamber 181 in the axial direction and is irradiated to the dust collection case 172, and is stored in the dust collection case 172 and the dust collection case 172. Disinfect (sterilize) the fine dust produced.

As described above, according to the second embodiment, the control unit 211 performs the first predetermined time T1, the ultraviolet ray from the timing when the electric blower 31 is set off by the setting button 22 while the electric blower 31 is operating. The lamp 67 is operated to sterilize the inside of the air passage W, in the present embodiment, by irradiating ultraviolet rays to the second separated dust collecting portion 27, for example, to circulate the exhaust air of an electric blower and to generate heat. Compared with the case of sterilization (sterilization) by the use of the above, it is possible to reduce the noise, and the ultraviolet rays irradiated from the ultraviolet lamp 67 are stronger than those for generating the oxidation-reduction action of the photocatalyst. Since the light is sterilization (sterilization) light having a sterilization (sterilization) effect by destroying, the sterilization (sterilization) can be performed in a short time. Therefore, power saving of the vacuum cleaner 11 can be achieved.

In addition, the electric blower 31 is considered to increase the amount of dust collected in the second separated dust collecting unit 27 and to increase the amount of germs in the air passage W (second separated dust collecting unit 27) as it is operated for a long time. Therefore, the first predetermined time T1 for operating the ultraviolet lamp 67 is changed corresponding to the operation time of the previous electric blower 31. Specifically, the longer the operation time of the electric blower 31 is, the first predetermined time T1 is. Is set longer, the air passage W (second separated dust collecting portion 27) can be sterilized (sterilized) more effectively.

Next, a third embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 2nd Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

In this third embodiment, instead of the control of the second embodiment, the control means 211 is able to supply the ultraviolet lamp 67 to the electric blower 31 from the commercial AC power source e, in other words, the plug portion. T2 is operated for a predetermined time from the timing (plug-in) at which 121a is connected to the commercial AC power source e.

In addition, the control means 211 is connected to the electric blower 31 when the electric blower 31 is turned on by the setting button 22 before the predetermined time T2 has elapsed from the above timing when the plug unit 121a is connected to the commercial AC power source e. The ultraviolet lamp 67 is continuously operated during the operation of 31. That is, the control unit 211 operates the ultraviolet lamp 67 until a predetermined time T2 elapses from the above timing when the plug unit 121a is connected to the commercial AC power source e, regardless of whether or not an operation for starting the electric blower 31 is performed. Continue.

That is, as shown in the flowchart of FIG. 13, the control unit 211 determines whether or not the plug unit 121a is connected to the commercial AC power source e (whether or not it is plugged in) (step 11). If it is determined in step 11 that the plug unit 121a is not connected to the commercial AC power source e (not plugged in), step 11 is repeated. If it is determined in step 11 that the plug unit 121a is connected to the commercial AC power source e (plugged in), the control unit 211 activates the timer T and turns on the ultraviolet lamp 67 (activates the activation). (Step 12).

Next, the control means 211 determines the timing when the plug unit 121a is connected to the commercial AC power source e, that is, whether or not a predetermined time T2 has elapsed since the ultraviolet lamp 67 is turned on (step 13). If it is determined in step 13 that the predetermined time T2 has elapsed, the control unit 211 stops the timer T and the ultraviolet lamp 67 (step 14), and the setting button 22 activates the operation, that is, the electric blower 31 is turned on. It is determined whether it has been set (step 15). If it is determined in this step 15 that ON is not set, step 15 is repeated. If it is determined that ON is set, the electric blower 31 is activated in the operation mode set by the setting button 22. (Step 16).

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

After this step 18, the control means 211 determines the timing at which the plug unit 121a is connected to the commercial AC power source e, that is, whether or not a predetermined time T2 has elapsed since the lighting of the ultraviolet lamp 67 (step 19). When it is determined that T2 has not elapsed, step 19 is repeated, and when it is determined that the predetermined time T2 has elapsed, the timer T and the ultraviolet lamp 67 are stopped (step 20). In step 19, when the electric blower 31 is set off by the setting button 22 before the predetermined time T2 elapses, the control unit 211 immediately stops both the ultraviolet lamp 67 and the electric blower 31, for example. Alternatively, the electric blower 31 may be stopped together with the ultraviolet lamp 67 after a predetermined time T2 has elapsed from the timing at which the plug unit 121a is connected to the commercial AC power source e, or the electric blower 31 is stopped and then the plug The lighting of the ultraviolet lamp 67 may be continued until a predetermined time T2 elapses from the timing when the unit 121a is connected to the commercial AC power source e. The timer T may be reset simultaneously with the stop of step 14 or step 20, or may be reset immediately before being started in step 12.

According to the third embodiment described above, the ultraviolet ray lamp starts from the timing when the control unit 211 can supply power to the electric blower 31 from the commercial AC power source e, that is, the timing when the plug part 121a is connected to the commercial AC power source e. 67 is operated for T2 for a predetermined time to sterilize by irradiating ultraviolet rays to the air passage W, in this embodiment the second separated dust collecting portion 27, for example, by circulating the exhaust air of an electric blower and its heat. Compared with the case of sterilization (sterilization) by the use of the above, it is possible to reduce the noise, and the ultraviolet rays irradiated from the ultraviolet lamp 67 are stronger than those for generating the oxidation-reduction action of the photocatalyst. Since the light is sterilization (sterilization) light having a sterilization (sterilization) effect by destroying, the sterilization (sterilization) can be performed in a short time. Therefore, power saving of the vacuum cleaner 11 can be achieved.

In addition, for example, when the period from the previous cleaning to the current cleaning is open, it is considered that germs are growing inside the air passage W (second separated dust collecting portion 27). By performing sterilization (sterilization) with the ultraviolet lamp 67 before starting the cleaning, that is, before the electric blower 31 is started, it is possible to reliably prevent the generation of a strange odor in the exhaust when the electric blower 31 is started.

Furthermore, when the electric blower 31 is set to ON by the setting button 22 before the predetermined time T2 has elapsed from the timing when the plug unit 121a is connected to the commercial AC power source e, the electric blower 31 continues during operation. By operating the ultraviolet lamp 67, there is no problem that the electric blower 31 does not start even though the setting button 22 is operated, and the air passage W (second separated dust collecting portion 27) Can be surely sterilized (sterilized).

Note that the second and third embodiments may be combined. That is, the control of the third embodiment may be performed before the vacuum cleaner 11 is started, and the control of the second embodiment may be performed when the driven vacuum cleaner 11 is stopped. . At this time, for example, in step 19 of the third embodiment, when the electric blower 31 is set off by the setting button 22 before the second predetermined time T2, which is a predetermined time, has passed, the control unit 211 For example, the timer T may be reset and the process may proceed to step 2 of the second embodiment.

According to at least one of the second and third embodiments, the first separated dust collecting unit 26 that swirls the dust-containing air sucked by the driving of the electric blower 31 and collects the dust by centrifugal separation. And the second separated dust collecting portion 27 are connected in multiple stages, and the second separated dust collecting portion 27 located on the downstream side is irradiated with ultraviolet rays from an ultraviolet lamp 67, thereby effectively removing germs by ultraviolet rays. it can.

In the second and third embodiments, the first separated dust collecting unit 26 and the second separated dust collecting unit 27 can have any configuration as long as dust can be collected from the dust-containing air.

Further, the ultraviolet lamp 67 can be configured to irradiate ultraviolet rays at any location in the air passage W.

Moreover, in each said embodiment, when the 2nd separated dust collection part 27 is shape | molded with the synthetic resin, it plated to the location which ultraviolet rays hit so that it may not deteriorate with the ultraviolet rays irradiated from the ultraviolet lamp 67 etc. A countermeasure may be taken, and for example, a material other than a synthetic resin may be provided using a member that is not deteriorated (not easily deteriorated) by ultraviolet rays.

Further, the vacuum cleaner 11 is not limited to a canister type, for example, an upright type in which a floor brush 19 is connected to the lower part of a vacuum cleaner body 13 that is vertically long, and a floor brush 19 is directly attached to the vacuum cleaner body 13. A handy type that is connected and cleaned while carrying the cleaner main body 13 or a robot type that the cleaner main body 13 self-runs by driving wheels (running wheels) or autonomously travels can be used.
