DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, a dust suction device 10 according to one embodiment of the present invention and a vacuum cleaner system S including the same will be described in detail with reference to the drawings. In the following description, before describing the configuration of the dust suction device 10 in detail, an overview will be given of the configuration of a vacuum cleaner 200 used together with the dust suction device 10 in the vacuum cleaner system S. In addition, in the following description, unless otherwise specified, the positional relationships in the up-down direction, front-rear direction, left-right direction (width direction), etc. will be described based on the state in which the vacuum cleaner 200 is erected as shown in FIG.

[0011] <General configuration of vacuum cleaner 200> As shown in Figures 1 and 2, the vacuum cleaner 200 is a vacuum cleaner having a stick-shaped (vertical) appearance. The vacuum cleaner 200 may be, for example, a rechargeable type, or a type that obtains power from an external power source via a power cord. As shown in Figures 1 and 2, the vacuum cleaner 200 includes a vacuum cleaner main body 210, a handle unit 220, a dust collection unit 250, an extension tube 280, and a suction tool 290.

[0012] Cleaner main body 210 forms the main body of vacuum cleaner 200 and is a part that exerts a suction force to collect dust. Specifically, as shown in Fig. 2, cleaner main body 210 includes, inside cleaner main body case 212 forming a housing, electric blower 214 for sucking air and generating an airflow, battery 215, other electronic components, drive circuits, etc.

[0013] A suction port 238y for connecting an extension tube 280 or a suction tool 290 is provided at the lower end side of the cleaner body 210 (one end side in the longitudinal direction of the cleaner body 210). The cleaner body 210 has a pipe section 238x that forms the suction port 238y at one end and forms an outlet communicating with an inlet of the dust collection section 250. The pipe section 238x extends in the up-down direction (the longitudinal direction of the cleaner body 210). The suction port 238y is provided at the lower side of the cleaner body 210 in the up-down direction.

[0014] Handle portion 220 is a portion provided for a user of vacuum cleaner 200 to grip vacuum cleaner main body 210. Handle portion 220 is provided on the upper end side of vacuum cleaner main body 210 (the other end side in the longitudinal direction of vacuum cleaner main body 210). Handle portion 220 forms an opening 222 between vacuum cleaner main body 210 and handle portion 220 for inserting a hand.

[0015] The dust collecting section 250 is a section where dust sucked by the electric vacuum cleaner 200 is collected. The dust collecting section 250 is disposed below the electric blower 214. In other words, the dust collecting section 250 is aligned with the pipe section 238x in the front-rear direction (the short side direction of the vacuum cleaner main body section 210). The dust collecting section 250 is provided so as to be continuous with the vacuum cleaner main body section 210. The dust collecting section 250 is of a cyclone type capable of centrifuging at least a part of dust from the air sucked into the dust collecting container 252 by the operation of the electric blower 214. The dust collecting section 250 is capable of opening and closing the bottom section 254 of the dust collecting container 252. The dust collecting section 250 can open the bottom section 254 when the dust collecting container 252 is fitted into the receiving section 40 of the dust suction device 10 described in detail later. Dust collection unit 250 has a locking mechanism that locks bottom 254 in a closed state. This locking mechanism can be released regardless of whether vacuum cleaner 200 is attached to dust suction device 10 or not. In other words, when vacuum cleaner 200 is detached from dust suction device 10, the user can operate the locking mechanism (locking portion and locked portion) (for example, by operating a button or releasing the lock) to release the lock of the locking portion from the locked portion.

[0016] Extension tube 280 is a cylindrical member that detachably connects cleaner body 210 and suction tool 290. One end of extension tube 280 is shaped so that it can be inserted into suction port 238y provided in tube section 238x of cleaner body 210, and the other end is shaped so that it can be connected to suction tool 290. By connecting cleaner body 210 and suction tool 290 via extension tube 280, a continuous path (air passage) from suction tool 290 to cleaner body 210 can be formed.

[0017] Suction tool 290 is connected directly to suction port 238y of cleaner body 210, or indirectly via extension tube 280. Suction tool 290 has suction port 292 (see FIG. 10) and joint part 294. Suction port 292 opens toward the bottom. In addition, joint part 294 is connectable to suction port 238y or extension tube 280. Characteristic parts of suction tool 290 will be described in detail later.

[0018] ≪Dust suction device 10≫ The dust suction device 10 is for recovering dust collected in the dust collecting section 250 of the vacuum cleaner 200, and supports the vacuum cleaner 200. The bottom section 254 can be opened while the dust suction device 10 supports the vacuum cleaner 200. A release mechanism for releasing the lock mechanism described above may be provided in the dust suction device 10, or the lock mechanism may be exposed from the dust suction device 10 so that the user can release the lock mechanism by directly touching it. When the lock mechanism is released, the bottom section 254 opens. The dust suction device 10 can also be used to suck up dust attached to a dust collector other than the vacuum cleaner 200, and this function may be performed alone. The dust collector may or may not be attached to the dust suction device 10. As shown in FIGS. 1 to 4, the dust suction device 10 has a device main body 20 and a dust collecting section 50.

[0019] As shown in Figs. 1 to 4, the device body 20 has a peripheral portion 30 having a front portion 22, a rear portion 24, a right side portion 26, and a left side portion 28, and is configured as a hollow box body closed at the top and bottom by a top portion 32 and a bottom portion 34. The device body 20 has a vacuum cleaner engagement portion 22a in the front portion 22 that can engage with and support the electric vacuum cleaner 200 (extension tube 280) in an upright state, although this is not an essential component. Therefore, the front portion 22 is a portion that exists on the rear side of the electric vacuum cleaner 200 in a supported state in the front-rear direction. The rear portion 24 is a portion that is located rearward in the front-rear direction from the front portion 22. The right side portion 26 and the left side portion 28 are side portions that face each other in the left-right direction perpendicular to the front-rear direction.

[0020] As shown in Fig. 4 etc., the device body 20 has a shape bent into a substantially "L" shape when viewed from the rear (an inverted "L" shape when viewed from the front). As shown in Figs. 1 to 4 and 6 etc., the device body 20 has a first body component 36 extending in the up-down direction on the right side 26 side, and a second body component 38 extending in the left-right direction on the bottom 34 side. In the device body 20, the first body component 36 and the second body component 38 are in communication with each other.

[0021] The first main body component 36 is a portion that is connected to the receiving part 40, which will be described in detail later, and the dust collecting part 50. The first main body component 36 has an introduction part 36a that is provided so as to communicate with the receiving part 40, and an exhaust path component 36b that communicates in the vertical direction.

[0022] Here, the receiving part 40 can be connected by fitting the dust collection part 250 (dust collection container 252) of the above-mentioned vacuum cleaner 200. The receiving part 40 is connected to the first main body component 36 via a connecting pipe 42. The receiving part 40 is provided so as to rise upward from the first main body component 36. As shown by the two-dot chain line in FIG. 2, the dust collection container 252 of the dust collection part 250 can open the bottom part 254 when it is fitted into the receiving part 40. Therefore, by fitting the dust collection container 252 into the receiving part 40 and opening the bottom part 254, the dust collected in the dust collection container 252 can be moved to the first main body component 36 via the connecting pipe 42. The connecting pipe 42 is connected to the introduction part 36a of the first main body component 36. Therefore, the device body 20 can allow the dust discharged from the dust collection container 252 in the receiving portion 40 to reach the introduction portion 36a of the first main body forming portion 36 via the connecting pipe 42.

[0023] As shown in FIG. 4, the first main body component 36 is configured to be open toward the rear part 24 at the connection point with the dust collecting part 50. Specifically, the introduction part 36a is open toward the rear part 24 through the introduction port 36c. Moreover, the exhaust path component 36b extends in the vertical direction and is open toward the rear part 24. By attaching the dust collecting part 50 to the rear part 24 side of the first main body component 36, the first main body component 36 can communicate with the dust collecting part 50 through the introduction part 36a and form a passage for exhausting air from the dust collecting part 50 by the exhaust path component 36b and the dust collecting part 50. Therefore, by attaching the dust collecting part 50 to the first main body component 36, a series of ventilation paths can be formed to introduce the dust-containing air supplied from the receiving part 40 through the connection pipe 42 into the dust collecting part 50 and to exhaust the air from the dust collecting part 50.

[0024] The second body component 38 is a part provided below the first body component 36 so as to communicate with the first body component 36. As shown in Figs. 2, 6, and 7, the second body component 38 is provided with an electric blower 44. Therefore, the device body 20 can generate an airflow from the receiving part 40 through the first body component 36 and the dust collecting part 50 to the second body component 38 by operating the electric blower 44 in a state in which the dust collecting part 50 is attached to the first body component 36 by operating a switch or detecting the attachment of the electric vacuum cleaner 200. In addition, the airflow that has flowed into the second body component 38 can be discharged from an exhaust port 46 provided in the second body component 38. A filter 48 is provided at the boundary between the first body component 36 and the second body component 38. The filter 48 can be a single filter or a combination of multiple filters, but in this embodiment, it is composed of a first filter 48a and a second filter 48b, and the two filters are used in a state in which they are overlapped. For example, the upper first filter 48a is a pleated filter, and the lower second filter 48b is a sponge filter. By providing such filters 48, dust contained in the airflow introduced into the first main body component 36 can be prevented from crossing the boundary between the first main body component 36 and the second main body component 38 and flowing into the electric blower 44.

[0025] The dust collecting unit 50 is a part that collects dust sucked from the electric vacuum cleaner 200 by operating the electric blower 44. The dust collecting unit 50 has a dust collecting container 52 and a locking structure 90.

[0026] As shown in FIG. 4, the dust collection container 52 is a container that is detachable from the device body 20. The dust collection container 52 is provided so as to be exposed from the device body 20 when attached to the device body 20 (the outer surface of the device body 20). In this embodiment, the dust collection container 52 can be attached in a state where it is joined to an open end that is opened at the rear part 24 in the first main body forming part 36 of the device body 20. Note that it is preferable to provide a seal member 55 on the opposing surfaces between the dust collection container 52 and the device body 20 so that the suction force of the electric blower 44 can easily act on the dust collection container 52. In this embodiment, the seal member 55 is provided on the device body 20 side, but the seal member 55 may be provided on the dust collection container 52 side.

[0027] As shown in FIG. 5 and other figures, the dust-collecting container 52 is a box-shaped container surrounded on all four sides by four wall surfaces (peripheral walls) consisting of a first side wall portion 52a to a fourth side wall portion 52d, and closed at the top and bottom by an upper wall portion 52e and a lower wall portion 52f. The first side wall portion 52a is a wall portion that forms a surface on the device main body 20 side (front portion 22 side) in a state where the dust-collecting container 52 is attached to the device main body 20. The second side wall portion 52b is a wall portion that faces the first side wall portion 52a and forms a surface on the rear portion 24 side. The third side wall portion 52c is a wall portion that forms a surface on the left side portion 28 side, and the fourth side wall portion 52d is a wall portion that faces the third side wall portion 52c and forms a surface on the right side portion 26 side. The upper wall portion 52e is a wall portion that forms a surface on the top portion 32 side of the dust-collecting container 52. The lower wall portion 52f faces the third side wall portion 52c and is a wall portion forming the surface on the side of the bottom portion 34. The dust collection container 52 has an inlet portion 60, an outlet portion 62, a partition portion 64, and a discharge portion 66. The top portion 32 is provided with a grip portion 67.

[0028] The inlet 60 is a portion that serves as an inlet for dust and air to the dust collection container 52. The inlet 60 is provided at a position that is above the outlet 62 when the dust collection container 52 is attached. The inlet 60 may be provided, for example, on any of the peripheral walls consisting of the first side wall 52a to the fourth side wall 52d of the dust collection container 52, or on the upper wall 52e. In this embodiment, the inlet 60 is formed by an inlet 70 provided in the first side wall 52a so as to open at a position corresponding to the inlet 36c of the introduction part 36a provided in the first main body component 36 of the device body 20. Therefore, when the dust collection container 52 is attached to the first main body component 36 of the device body 20, the inlet 60 is in communication with the introduction part 36a of the device body 20.

[0029] The outflow section 62 is for discharging air to the outside of the dust collection container 52. The outflow section 62 has an outflow opening 72 provided in the first side wall section 52a of the dust collection container 52. The outflow opening 72 is provided at a position that is vertically lower than the inflow port 70 that constitutes the inflow section 60 in a state in which the dust collection container 52 is attached to the first main body forming section 36 of the device main body 20.

[0030] The partition 64 separates the inlet 60 and the outlet 62 inside the dust collection container 52. The partition 64 functions as an obstructing member for preventing the air containing dust from flowing directly from the inlet 60 toward the outlet 62. The partition 64 also functions to guide the air that flows from the inlet 60 into the dust collection container 52 so that it flows downward and then upward. This ensures that the dust that flows into the dust collection container 52 from the inlet 60 together with the air falls into the dust collection container 52, and prevents the dust from flowing out of the outlet 62 along with the air.

[0031] The partition 64 may have any shape or structure as long as it can perform the above-mentioned function. In this embodiment, the partition 64 is provided so as to protrude from the first side wall 52a toward the second side wall 52b (rear portion 24). As shown in Figs. 2 and 6, it is preferable to use a partition wall 64a formed in a bent or curved shape (curved in an arc in the illustrated example). In addition, a communication portion 65 that communicates the upper side and lower side of the partition 64 is formed between the partition 64 and the second side wall 52b.

[0032] The partition wall 64a is provided on the first side wall 52a of the dust collection container 52 at or above the upper edge of the outflow opening 72 and protrudes from the first side wall 52a toward the second side wall 52b (rear 24) with the lower edge of the inflow port 70 or a portion lower than the upper edge as a base end. The partition wall 64a is preferably formed so as to curve downward from the first side wall 52a, which is the base end side, toward the second side wall 52b (rear 24). The partition wall 64a is formed so as to reach the lower end of the opening area of ​​the outflow opening 72 or further below the lower end at the terminal end side (opposite the base end side). The partition wall 64a is connected to the third side wall 52c and the fourth side wall 52d at both ends in the width direction (left-right direction) of the dust collection container 52. As a result, the partition portion 64 is surrounded by the first side wall portion 52a, the third side wall portion 52c, the fourth side wall portion 52d, and the partition wall 64a at the terminal end side (lower end side) of the partition wall 64a, forming a hood portion 68 that communicates with the outflow portion 62. The hood portion 68 has an opening portion 68a that opens downward (toward the lower wall portion 52f). Note that in the hood portion 68, the walls that form both ends in the width direction (left-right direction) of the dust collection container 52 may be separate from the third side wall portion 52c and the fourth side wall portion 52d.

[0033] A filter 74 for filtering air discharged to the outside of the dust container 52 is disposed in the hood portion 68 so as to be detachable from the outside of the dust container 52. The filter 74 is accessible from the outlet opening 72 and is detachable from the outside of the dust container 52 (see FIG. 5). The filter 74 can be disposed in the middle of the hood portion 68 or in the outlet opening 72 which is the end of the hood portion 68, but in this embodiment, the filter 74 is disposed in the opening 68a which is the beginning of the hood portion 68. That is, the opening 68a functions as a filter disposing opening 76 for disposing the filter 74. In the filter disposing opening 76, a support portion for supporting the filter 74 is formed on the opening edge. The opening 68a (filter disposing opening 76) is formed by using the first side wall portion 52a and the partition wall 64a. The opening 68a is disposed at a position having a height equal to or higher than the center in the vertical direction in the dust container 52. In other words, the opening 68 a is provided at a higher position in the dust container 52 than the discharge portion 66 .

[0034] The discharge section 66 is a section for discharging dust collected in the dust collection container 52. The discharge section 66 has a disposal opening 80 and an opening / closing section 82. The disposal opening 80 is an opening for disposing of dust from the dust collection container 52. The opening / closing section 82 is capable of opening and closing the disposal opening 80. The opening / closing section 82 can be configured by a detachable cover or the like for the disposal opening 80, but in this embodiment, it is configured by a pivotable door-like opening / closing door 84. When the dust collection container 52 is attached to the device body 20, the opening / closing door 84 is covered by the device body 20. The opening / closing door 84 is provided with an opening / closing operation section 86, and the opening / closing door 84 can be set to a locked state in which it cannot be opened or closed, or to an unlocked state in which it can be opened or closed, by operating the opening / closing operation section 86.

[0035] 1, 3, 8, etc., the dust suction device 10 has a locking structure 90 for locking the dust collection unit 50 to the device body 20. The locking structure 90 may be any suitable structure capable of locking the dust collection unit 50 to the device body 20, but in this embodiment, the locking structure 90 has a first locking structure 90a consisting of a combination of a first engaged portion 92 provided so as to protrude upward from the top portion 32 of the device body 20 and a first engaging portion 94 provided on the first side wall portion 52a of the dust collection unit 50, and a second locking structure 90b consisting of a combination of a second engaged portion 96 provided on the connection pipe 42 and a second engaging portion 98 provided so as to be able to protrude and retract from the first side wall portion 52a of the dust collection unit 50.

[0036] The first locking structure 90a can lock the device body 20 and the dust collecting unit 50 by attaching the first engaging portion 94 from above to the first engaged portion 92 formed in an upwardly convex shape. On the other hand, the locking of the device body 20 and the dust collecting unit 50 can be released by lifting the dust collecting unit 50 and moving the first engaging portion 94 on the dust collecting unit 50 side away from the first engaged portion 92 on the device body 20 side. In addition, the second locking structure 90b is in a state where the dust collecting unit 50 is locked to the device body 20 so that it cannot move upward by fitting the second engaging portion 98 into the second engaged portion 96 on the connection pipe 42 side. This causes the dust collecting unit 50 to be locked so that it cannot be lifted up and removed from the device body 20. Further, the second engagement portion 98 is biased so as to protrude from the first side wall portion 52a of the dust collecting unit 50, and can be retracted into the inside of the first side wall portion 52a by operating an operation portion 98a exposed to the outside at the upper wall portion 52e of the dust collecting unit 50. Therefore, when removing the dust collecting unit 50 attached to the device body 20, the second engagement portion 98 is retracted by the operation portion 98a to release the engagement between the second engaged portion 96 and the second engagement portion 98, and then the dust collecting unit 50 is lifted to release the engagement at the first locking structure portion 90a, thereby removing the dust collecting unit 50 from the device body 20.

[0037] As shown in FIG. 7 etc., the right side 26 or the left side 28 (the left side 28 in this embodiment) of the device body 20 is provided with a storage section 110 for storing the dust collector 100. The dust collector 100 has a cleaning section 102 for cleaning dust, and a handle section 104. A mop made of microfiber, cotton, or other material that easily becomes static is attached to the cleaning section 102. The storage section 110 is cylindrical and can store at least the cleaning section 102 of the dust collector 100.

[0038] The storage section 110 is provided with a cleaning unit dust suction section 120. The cleaning unit dust suction section 120 is for suctioning dust attached to the cleaning unit 102 of the dust collector 100 stored in the storage section 110. The cleaning unit dust suction section 120 has a suction port 122 that opens toward the inside of the storage section 110. The cleaning unit dust suction section 120 communicates with the device body 20 or the dust collector 50 via a cleaning unit suction communication air passage 124. In this embodiment, the cleaning unit dust suction section 120 communicates with the connection pipe 42 of the device body 20 via the cleaning unit suction communication air passage 124. Therefore, by operating the electric blower 44 provided in the device body 20, a suction force can be generated at the suction port 122 via the cleaning unit suction communication air passage 124. Therefore, by operating electric blower 44 with cleaning part 102 of dust collector 100 housed in housing part 110 , dust adhering to cleaning part 102 can be sucked in through suction port 122 .

[0039] <<Variations>> As shown in Fig. 1, the above-mentioned dust suction device 10 can be installed in an upright state by engaging the suction tool 290 of the vacuum cleaner 200 with the vacuum cleaner engaging part 22a in a state where the suction tool 290 is in a position along the front part 22 of the device body 20. However, the present invention is not limited to this, and instead of or in addition to the configuration of the vacuum cleaner engaging part 22a, for example, a mounting part 150 as shown in Figs. 9 and 10 can be provided, and the vacuum cleaner 200 can be installed with the suction tool 290 placed on the mounting part 150. In addition, when the above-mentioned mounting part 150 is provided, it is preferable to provide a configuration in which the suction tool dust suction part 160 is provided so as to face the bottom side of the suction tool 290 placed on the mounting part 150. Dust suction device 10 may be configured to include suction tool dust suction section 160 in addition to the configuration for recovering dust collected in dust collection section 250 in vacuum cleaner 200, or may be configured to include only suction tool dust suction section 160. The tip of mounting section 150 is configured as a stopper section that protrudes upward to support the front end of suction tool 290, but the stopper section may be eliminated so as not to impede forward and backward movement of suction tool 290.

[0040] Specifically, the suction tool dust suction section 160 may include a slit 164 extending in the width direction (left-right direction) of the suction tool 290 in the suction tool arrangement section 162 where the suction tool 290 is arranged in the placement section 150, and a suction tool suction communication air passage 166 communicating with the slit 164. The suction tool suction communication air passage 166 is an air passage communicating with the device main body 20 or the dust collection section 50, similar to the above-mentioned cleaning section suction communication air passage 124. Therefore, by operating the electric blower 44, a suction force can be generated in the slit 164.

[0041] The placement portion 150 may include a cleaning member 170 in addition to the above-mentioned slit 164 and the suction tool suction communication air passage 166.

The vacuum cleaner in this patent document is configured such that valves are provided on both the vacuum cleaner main body and the installation stand, and the valves are opened by the airflow from the fan motor to discharge dust from the dust case on the vacuum cleaner main body side to the dust case on the installation stand side.

[0044] Here, the vacuum cleaner of the above-mentioned patent document has a structure in which the dust case is disposed inside the installation stand, and therefore there is a problem in that it is difficult to attach and detach the dust case.

[0045] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a dust suction device in which the dust collection section can be easily attached and detached.

[0046] (1-1) The dust suction device 10 of the present invention is for recovering dust collected in an electric vacuum cleaner 200, and comprises an apparatus main body 20 having an electric blower 44 that generates suction force, and a dust collection section 50 that collects dust sucked out of the vacuum cleaner 200 by the electric blower 44 in a dust collection container 52, the dust collection section 50 having an inlet section 60, an outlet section 62 and an exhaust section 66 in the dust collection container 52, the dust collection container 52 being detachable from the apparatus main body 20 and exposed from the apparatus main body 20 when attached to the apparatus main body 20, the suction of the electric blower 44 causes air to flow into the dust collection container 52 from the inlet section 60, and the air in the dust collection container 52 flows out from the outlet section 62, and the dust in the dust collection container 52 can be disposed of from the exhaust section 66.

[0047] As described above in (1-1), the dust suction device 10 has a dust collection section 50 for collecting dust sucked out from the vacuum cleaner 200 that is exposed from the device body 20 when attached to the device body 20, thereby making it possible to easily attach and detach the dust collection container 52 to and from the device body 20.

[0048] (1-2) In the dust suction device 10 relating to (1-1) above, the discharge section 66 has a disposal opening 80 for disposing of dust from the dust collection container 52 and an opening / closing door 84 capable of opening and closing the disposal opening 80, and it is preferable that when the dust collection section 50 is attached to the device main body 20, the opening / closing door 84 is covered by the device main body 20.

[0055] By configuring the dust suction device 10 as described above in (1-5), the filter 74 provided in the outlet opening 72 can capture dust contained in the air discharged from the dust collection section 50. This allows the dust suction device 10 to suppress leakage of dust to the outside of the dust collection section 50 and increase the dust collection rate.

[0056] (1-6) In the dust suction device 10 relating to any of (1-1) to (1-5) above, the dust collection section 50 has a filter 74 that filters air flowing from the inlet section 60 toward the outlet section 62, and the outlet section 62 defines a filter placement opening 76 for discharging air outside the dust collection container 52 by the first side wall section 52a and the partition section 64, and the filter 74 is preferably arranged in the filter placement opening 76.

[0057] By configuring the dust suction device 10 as described above in (1-6), the filter 74 disposed in the filter placement opening 76 formed by the first side wall portion 52a and the partition portion 64 can capture dust contained in the air discharged from the dust collection section 50. This allows the dust suction device 10 to suppress leakage of dust to the outside of the dust collection section 50 and increase the dust collection rate.

[0058] (1-7) In the dust suction device 10 relating to any of (1-1) to (1-6) above, a dust collector 100 having a cleaning part 102 for cleaning dust and a handle part 104, a storage part 110 for storing at least the cleaning part 102, and a cleaning part suction communication air duct 124 that connects the device body 20 or the dust collection part 50 to the storage part 110, and it is preferable that the suction force of the electric blower 44 acts on the storage part 110 via the cleaning part suction communication air duct 124.

[0059] By configuring the dust suction device 10 as described above in (1-7), and storing the dust collector 100 in the storage section 110, the dust adhering to the cleaning section 102 can be sucked in by the suction force of the electric blower 44 acting via the cleaning section suction communication air passage 124. This allows the dust suction device 10 to suck in not only the dust collected in the vacuum cleaner 200, but also the dust adhering to the cleaning section 102 of the dust collector 100.

[0060] (1-8) In the dust suction device 10 according to any one of the above (1-1) to (1-7), the dust collection unit 50 may have a locking structure for locking with the device body 20.

This allows the dust suction device 10 to fully utilize the suction power of the electric blower 44 provided in the device body 20.

[0062] [Dust suction device 10 according to the second embodiment of the present invention] Japanese Patent Application Laid-Open No. 2004-283327 discloses a vacuum cleaner that generates a suction airflow and collects dirt with the generated airflow, the vacuum cleaner comprising a vacuum cleaner main body having a dust case on the main body side that collects and stores dirt, and an installation stand having a dust case on the installation stand side that stores dirt from the dust case on the main body side, and when the vacuum cleaner main body is installed on the installation stand, the dirt in the dust case on the main body side of the vacuum cleaner main body is discharged into the dust case on the installation stand side by utilizing the suction of a fan motor on the installation stand side.

[0063] Here, in the conventional technology described in the above patent document, there is a problem in that dust tends to gather toward the fan motor on the installation stand side, causing clogging of the ventilation holes in the partition wall upstream of the fan motor, thereby reducing suction performance.

[0064] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a dust suction device capable of reducing the deterioration of suction performance.

[0065] (2-1) The dust suction device 10 of the present invention is for recovering dust collected in an electric vacuum cleaner 200, and comprises an apparatus body 20 having an electric blower 44 that generates a suction force, and a dust collection section 50 that is detachable from the apparatus body 20 and collects dust sucked out of the electric vacuum cleaner 200 by the electric blower 44 in a dust collection container 52. The dust collection section 50 has an inlet section 60, an outlet section 62 provided vertically below the inlet section 60, and a discharge section 66 in the dust collection container 52, and by the suction of the electric blower 44, Air flows into the dust collection container 52 from the inlet portion 60, the air inside the dust collection container 52 flows out from the outlet portion 62, and the dust inside the dust collection container 52 can be disposed of from the outlet portion 66.

The dust collection container 52 is characterized in that it has a partition portion 64 located above the outlet portion 62 so that a communication portion 65 communicating with the outlet portion 62 is formed on the second side wall portion 52b side relative to the first side wall portion 52a.

[0066] By being configured as described above in (2-1), the dust suction device 10 of the present invention allows dust contained in the air introduced from the inlet portion 60 into the dust collection container 52 to fall through the communication portion 65 formed between the upper partition portion 64 of the outlet portion 62 and the second side wall portion 52b and accumulate on the bottom of the dust collection container 52, making it difficult for the dust to reach the outlet portion 62. As a result, the dust suction device 10 can improve the dust collection rate in the dust collection container 52 and reduce a decrease in the suction performance of the electric blower 44 caused by dust clogging the outlet portion 62.

[0067] (2-2) The dust suction device 10 of the present invention is for recovering dust collected in an electric vacuum cleaner 200, and comprises an apparatus body 20 having an electric blower 44 that generates a suction force, and a dust collection section 50 that is detachable from the apparatus body 20 and collects dust sucked out of the electric vacuum cleaner 200 by the electric blower 44 in a dust collection container 52, the dust collection section 50 having an inlet section 60, an outlet section 62 provided vertically below the inlet section 60, and a discharge section 66 in the dust collection container 52, By suction from the powered blower 44, air flows into the dust collection container 52 from the inlet portion 60, the air inside the dust collection container 52 flows out from the outlet portion 62, and the dust inside the dust collection container 52 can be disposed of from the outlet portion 66.
