[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-283327 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, in the conventional technology described in the above patent document, dust tends to collect toward the fan motor on the installation stand side, which causes clogging of the ventilation holes in the partition wall upstream of the fan motor, resulting in a decrease in suction performance.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a dust suction device that can reduce the deterioration of suction performance. [Means for solving the problem]

[0006] The dust suction device of the present invention is for recovering dust collected in an electric vacuum cleaner, and comprises a device main body having an electric blower that generates suction force, and a dust collection unit that is detachable from the device main body and collects dust sucked from the electric vacuum cleaner by the electric blower into a dust collection container, the dust collection unit having an inlet section, an outlet section that is located vertically below the inlet section, and an outlet section in the dust collection container, and air flows into the dust collection container from the inlet section due to suction by the electric blower, and the air in the dust collection container flows out from the outlet section, and the dust in the dust collection container can be disposed of from the outlet section, the dust collection container has at least a first side wall section having the outlet section and a second side wall section opposite the first side wall section, and the dust collection container has a partition section located above the outlet section on the second side wall section side of the first side wall section so that a communication section that communicates with the outlet section is formed.

[0007] With the dust suction device of the present invention configured as described above, dust contained in air introduced into the dust collection container from the inlet portion falls through the communication portion formed between the upper partition portion of the outlet portion and the second side wall portion and accumulates on the bottom of the dust collection container, making it difficult for the dust to reach the outlet portion. As a result, the dust suction device of the present invention can improve the dust collection rate in the dust collection container and reduce a decrease in the suction performance of the electric blower caused by dust clogging the outlet portion. [Effects of the Invention]

[0008] According to the present invention, it is possible to realize a dust suction device that can reduce the deterioration of suction performance. [Brief explanation of the drawings]

[0010] 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 below 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 the following description, unless otherwise specified, 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 the vacuum cleaner 200> As shown in Figures 1 and 2, the electric vacuum cleaner 200 is a vacuum cleaner having a stick-shaped (vertical) appearance. The electric vacuum cleaner 200 can 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 electric vacuum cleaner 200 includes a vacuum cleaner main body 210, a handle 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 the part that exerts suction power and performs the function of collecting dust. Specifically, as shown in Fig. 2, cleaner main body 210 includes, inside cleaner main body case 212 that forms the housing, electric blower 214 for sucking air and generating airflow, battery 215, other electronic components, a drive circuit, 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 also forms an outlet that communicates with an inlet of the dust collection section 250. The pipe section 238x extends in the vertical 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 vertical direction.

[0014] Handle portion 220 is a portion provided to allow a user of electric vacuum cleaner 200 to grip cleaner body portion 210. Handle portion 220 is provided on the upper end side of cleaner body portion 210 (the other end side in the longitudinal direction of cleaner body portion 210). Handle portion 220 forms an opening 222 between itself and cleaner body portion 210, through which a hand can be inserted.

[0015] The dust collection unit 250 is a portion where dust sucked by the electric vacuum cleaner 200 is collected. The dust collection unit 250 is disposed below the electric blower 214. In other words, the dust collection unit 250 is aligned with the pipe unit 238x in the front-to-rear direction (the short side direction of the vacuum cleaner main body 210). The dust collection unit 250 is provided so as to be continuous with the vacuum cleaner main body 210. The dust collection unit 250 is of a cyclone type that can centrifuge at least a portion of dust from the air sucked into the dust collection container 252 by the operation of the electric blower 214. The dust collection unit 250 is configured so that the bottom 254 of the dust collection container 252 can be opened and closed. The bottom 254 of the dust collection unit 250 can be opened when the dust collection container 252 is fitted into the receiving part 40 of the dust suction device 10, which will be 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. 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 pipe 280 is a cylindrical member that detachably connects cleaner body 210 and suction tool 290. One end of extension pipe 280 is shaped so that it can be inserted into suction port 238y provided in pipe portion 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 pipe 280, a continuous, communicating 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 vacuum cleaner body 210, or indirectly via extension pipe 280. Suction tool 290 has suction port 292 (see FIG. 10) and joint part 294. Suction port 292 opens toward the bottom. Joint part 294 can be connected to suction port 238y or extension pipe 280. Characteristic features of suction tool 290 will also be described in detail later.

[0018] ≪Dust suction device 10≫ The dust suction device 10 is used to recover dust collected in the dust collection unit 250 of the vacuum cleaner 200 and supports the vacuum cleaner 200. The bottom 254 can be opened while the dust suction device 10 supports the vacuum cleaner 200. A release mechanism for releasing the locking mechanism described above may be provided in the dust suction device 10, or the locking mechanism may be exposed from the dust suction device 10 so that a user can release it by directly touching it. When the locking mechanism is released, the bottom 254 opens. The dust suction device 10 can also be used to suck dust adhering to a dust collector separate from the vacuum cleaner 200, and this function may be independent. 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 includes a device main body 20 and a dust collection unit 50.

[0019] As shown in FIGS. 1 to 4 , the device main 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-like body closed at the top and bottom by a top portion 32 and a bottom portion 34. The device main body 20 has, in the front portion 22, a vacuum cleaner engagement portion 22a that can engage with and support the 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 is located rearward of the vacuum cleaner 200 in a supported state in the front-to-rear direction. The rear portion 24 is a portion that is located rearward of the front portion 22 in the front-to-rear direction. The right side portion 26 and the left side portion 28 are side portions that face each other in the left-to-right direction that is perpendicular to the front-to-rear direction.

[0020] As shown in Fig. 4 and other figures, the device body 20 has a shape that is 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 and other figures, the device body 20 has a first body component 36 that extends in the vertical direction on the right side 26 side, and a second body component 38 that extends in the horizontal 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 part 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 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 is connectable to the dust collection unit 250 (dust collection container 252) of the vacuum cleaner 200 described above by fitting it therein. 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 indicated by the two-dot chain line in FIG. 2 , the dust collection container 252 of the dust collection unit 250 has a bottom 254 that can be opened when fitted into the receiving part 40. Therefore, by fitting the dust collection container 252 into the receiving part 40 and opening the bottom 254, 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 main body 20 can make the dust discharged from the dust collection container 252 in the receiving portion 40 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 so that the connection portion with the dust collecting unit 50 is open toward the rear section 24. Specifically, the introduction portion 36a is open toward the rear section 24 via the introduction port 36c. The exhaust path component 36b extends in the vertical direction and is open toward the rear section 24. By attaching the dust collecting unit 50 to the rear section 24 side of the first main body component 36, the first main body component 36 is in communication with the dust collecting unit 50 via the introduction portion 36a, and a passage for exhausting air from the dust collecting unit 50 can be formed by the exhaust path component 36b and the dust collecting unit 50. Therefore, by attaching the dust collecting unit 50 to the first main body component 36, a series of ventilation paths can be formed that introduce dust-laden air supplied from the receiving portion 40 via the connecting pipe 42 into the dust collecting unit 50 and exhaust air from the dust collecting unit 50.

[0024] The second body component 38 is provided below the first body component 36 and is in communication 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 main body 20 can generate an airflow from the receiving portion 40 through the first body component 36 and the dust collecting unit 50 to the second body component 38 by operating the electric blower 44 with the dust collecting unit 50 attached to the first body component 36 upon operation of a switch or detection of attachment of the vacuum cleaner 200. The airflow that flows into the second body component 38 can be discharged through 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. In this embodiment, the filter 48 is formed by a first filter 48a and a second filter 48b, which are used in a stacked state. 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 side.

[0025] Dust collection unit 50 is a part that collects dust sucked from electric vacuum cleaner 200 by operating electric blower 44. Dust collection unit 50 has a dust collection 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 main body 20. When the dust collection container 52 is attached to the device main body 20 (the outer surface of the device main body 20), the dust collection container 52 is exposed from the device main body 20. In this embodiment, the dust collection container 52 can be attached by joining it to the open end of the rear portion 24 of the first main body constituent portion 36 of the device main body 20. Note that it is preferable to provide a sealing member 55 on the opposing surfaces between the dust collection container 52 and the device main 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 sealing member 55 is provided on the device main body 20 side, but the sealing member 55 may also be provided on the dust collection container 52 side.

[0027] As shown in FIG. 5 and other figures, the dust collection 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 the surface facing the device main body 20 (the front portion 22) when attached to the device main body 20. The second side wall portion 52b faces the first side wall portion 52a and forms the surface facing the rear portion 24. The third side wall portion 52c is a wall portion that forms the surface facing the left side portion 28, and the fourth side wall portion 52d faces the third side wall portion 52c and forms the surface facing the right side portion 26. The upper wall portion 52e is a wall portion that forms the surface facing the ceiling portion 32 of the dust collection container 52. The lower wall portion 52f faces the third side wall portion 52c and is a wall portion that forms 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. A grip portion 67 is provided on the top portion 32.

[0028] The inlet 60 is a portion that serves as an inlet for dust and air into the dust collection container 52. The inlet 60 is provided at a position that is higher than 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 that is provided in the first side wall 52a so as to open at a position corresponding to the inlet 36c of the introduction portion 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 portion 36a of the device body 20.

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

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

[0031] The partition 64 may have any shape or structure as long as it can perform the above-described 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 (the rear portion 24). As shown in Figures 2 and 6, it is preferable that the partition 64a is formed in a bent or curved shape (curved in an arc in the illustrated example). In addition, a communication portion 65 is formed between the partition 64 and the second side wall 52b, which connects the upper and lower sides of the partition 64.

[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 has a base end at or below the lower edge of the inflow opening 70, protruding from the first side wall 52a toward the second side wall 52b (toward the rear portion 24). The partition wall 64a is preferably curved downward from the base end, i.e., the first side wall 52a, toward the second side wall 52b (toward the rear portion 24). The partition wall 64a is formed so that its terminal end (opposite the base end) reaches the lower end of the opening region of the outflow opening 72 or even lower than that lower end. The partition wall 64a is connected to the third side wall 52c and the fourth side wall 52d at both widthwise (left-right) ends 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 wall portions that form both ends of the dust collection container 52 in the width direction (left-right direction) 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 outside the dust collection container 52 is disposed in the hood portion 68 so as to be detachable from the outside of the dust collection container 52. The filter 74 is accessible from the outlet opening 72 and can be attached and detached from the outside of the dust collection container 52 (see FIG. 5). The filter 74 can be disposed midway through the hood portion 68 or at the outlet opening 72, which is the terminal end of the hood portion 68. In this embodiment, the filter 74 is disposed at the opening 68a, which is the starting end of the hood portion 68. That is, the opening 68a functions as a filter placement opening 76 for placing the filter 74. A support portion for supporting the filter 74 is formed on the edge of the filter placement opening 76. The opening 68a (filter placement opening 76) is formed using the first side wall portion 52a and the partition wall 64a. The opening 68a is disposed at a height equal to or higher than the center of the dust collection container 52 in the up-down direction. 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 as a detachable cover for the disposal opening 80, but in this embodiment, it is configured as a pivotable door-like opening / closing door 84. The opening / closing door 84 is covered by the device body 20 when the dust collection container 52 is attached to the device body 20. The opening / closing door 84 is provided with an opening / closing operation section 86, and by operating the opening / closing operation section 86, the opening / closing door 84 can be placed in a locked state where it cannot be opened or closed, or in an unlocked state where it can be opened and closed.

[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 can be any suitable structure that can lock the dust collection unit 50 to the device body 20, but in this embodiment, the locking structure 90 has a first locking structure 90a that is made up of a first engaged portion 92 provided 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 that is made up of a second engaged portion 96 provided on the connecting pipe 42 and a second engaging portion 98 that is provided 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, which is formed in an upwardly convex shape. On the other hand, the lock between the device body 20 and the dust collecting unit 50 can be released by lifting the dust collecting unit 50 and separating the first engaging portion 94 on the dust collecting unit 50 side from the first engaged portion 92 on the device body 20 side. Furthermore, the second locking structure 90b has a second engaging portion 98 that fits into the second engaged portion 96 on the connecting pipe 42 side, thereby locking the dust collecting unit 50 to the device body 20 so that it cannot move upward. This locks the dust collecting unit 50 so that it cannot be lifted and removed from the device body 20. Furthermore, the second engaging 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 first side wall portion 52a by operating an operating portion 98a exposed to the outside on 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 engaging portion 98 is retracted by the operating portion 98a to release the engagement between the second engaged portion 96 and the second engaging portion 98, and then the dust collecting unit 50 is lifted to release the engagement at the first locking structure portion 90a, thereby allowing the dust collecting unit 50 to be removed from the device body 20.

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

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

[0039] <<Variations>> 1, the above-described dust suction device 10 is configured so that the vacuum cleaner 200 can be installed in an upright position by engaging the suction tool 290 of the vacuum cleaner 200 with the vacuum cleaner engagement part 22a while the suction tool 290 is oriented along the front part 22 of the device body 20. However, the present invention is not limited to this. Instead of or in addition to the configuration of the vacuum cleaner engagement part 22a, for example, a mounting part 150 as shown in FIGS. 9 and 10 may be provided so that the vacuum cleaner 200 can be installed with the suction tool 290 placed on the mounting part 150. Furthermore, when the above-described mounting part 150 is provided, it is preferable to provide the suction tool dust suction part 160 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 interfere with the forward and backward movement of suction tool 290.

[0040] Specifically, suction tool dust suction section 160 preferably includes slits 164 extending in the width direction (left-right direction) of suction tool 290 in suction tool placement section 162 where suction tool 290 is placed in mounting section 150, and suction tool suction communication air passage 166 communicating with slit 164. Similar to cleaning unit suction communication air passage 124 described above, suction tool suction communication air passage 166 is an air passage communicating with device main body 20 or dust collection section 50. Therefore, by operating electric blower 44, suction force can be generated in slit 164.

[0041] The mounting portion 150 may be provided with a cleaning member 170 in addition to the above-described slits 164 and suction tool suction communication air passage 166. The cleaning member 170 cleans at least one of the rotating brush 290a of the suction tool 290 and the brush member 290b provided on the bottom side of the suction tool 290. The cleaning member 170 may be formed of a comb-like member, brush-like member, blade, or cutting edge capable of scraping off hair or dust wrapped around the rotating brush 290a. The cleaning member 170 may also be formed of a frictionally charged member that is charged by friction with at least one of the rotating brush 290a of the suction tool 290 and the brush member 290b provided on the bottom side of the suction tool 290. The user may rub the bottom side of suction tool 290 against cleaning member 170 in a front-to-back direction, or friction may be generated by bringing rotating brush 290a, driven by a motor provided in suction tool 290, into contact with cleaning member 170. If cleaning member 170 is configured with frictionally charged portion 170a formed from a frictionally charged member, static electricity generated by friction can attract dust, hair, and the like adhering to the bottom side of suction tool 290. Frictionally charged portion 170a is a material that is easily negatively charged, such as polypropylene. To facilitate the removal of dust from the bottom side of suction tool 290 by moving suction tool 290 back and forth, cleaning member 170 is preferably arranged in a front-to-back alignment with slits 164 that form suction tool dust suction portion 160. Furthermore, if multiple slits 164 are provided in a front-to-back direction, cleaning member 170 may be arranged between the slits 164, 164, which are arranged in a front-to-back alignment.

[0042] <<Effects Obtained by the Configuration of the Dust Suction Device 10>> The effects and the like obtained by the configuration of the dust suction device 10 described above will be described below for each aspect of the present invention.

[0043] [Dust suction device 10 according to the first embodiment of the present invention] As disclosed in Japanese Patent Laid-Open No. 2004-283327, a conventional vacuum cleaner that collects dust using a generated airflow is provided, which includes a vacuum cleaner main body having a dust case on the main body side that collects and stores dust, and an installation stand having a dust case on the installation stand side that stores dust from the dust case on the main body, and which is characterized by having a means for discharging dust from the dust case on the main body side of the vacuum cleaner main body into the dust case on the installation stand side when the vacuum cleaner main body is installed on the installation stand. The vacuum cleaner disclosed 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] However, the vacuum cleaner disclosed in the above patent document has a structure in which the dust case is disposed inside the installation stand, which poses a problem in that it is difficult to attach and detach the dust case.

[0045] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a dust suction device in which the dust collection unit 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 from 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 and an outlet 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 outlet 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 main body 20 when attached to the device main body 20, thereby making it possible to easily attach and detach the dust collection container 52 to and from the device main body 20.

[0048] (1-2) In the dust suction device 10 according 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 that can open and close 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.

[0049] By configuring the dust suction device 10 as described above in (1-2), it is possible to prevent the opening and closing door 84 from opening unexpectedly when the dust collection container 52 is attached to the device body 20.

[0050] (1-3) In the dust suction device 10 according to (1-1) or (1-2) above, the dust collection container 52 preferably has at least a first side wall portion 52a on which the outlet portion 62 is provided and a second side wall portion 52b opposite the first side wall portion 52a, the inlet portion 60 is provided above the outlet portion 62, and the dust collection container 52 preferably has a partition portion 64 located above the outlet portion 62 on the second side wall portion 52b side relative to the first side wall portion 52a so as to form a communication portion 65 communicating with the outlet portion 62.

[0051] By configuring the dust suction device 10 as described above in (1-3), dust contained in the air introduced into the dust collection container 52 from the inlet portion 60 falls 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 accumulates on the bottom of the dust collection container 52, making it difficult for the dust to reach the outlet portion 62. This allows the dust suction device 10 to improve the dust collection rate in the dust collection container 52.

[0052] (1-4) In the dust suction device 10 according to any one of the above (1-1) to (1-3), the dust collection section 50 preferably has a filter 74 that filters air flowing from the inlet section 60 toward the outlet section 62.

[0053] By configuring the dust suction device 10 as described above in (1-4), the filter 74 can capture dust contained in the air flowing from the inlet portion 60 to the outlet portion 62, thereby cleaning the air flowing downstream from the outlet portion 62. This allows the dust suction device 10 to improve the dust collection rate in the dust collection section 50.

[0054] (1-5) In the dust suction device 10 according to any one of (1-1) to (1-4) above, the dust collection section 50 has a filter 74 that filters air flowing from the inlet section 60 toward the outlet section 62, the outlet section 62 has an outlet opening 72 for discharging air outside the dust collection container 52, and the filter 74 is preferably arranged in the outlet opening 72.

[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 unit 50. This allows the dust suction device 10 to prevent dust from leaking outside the dust collection unit 50, thereby increasing the dust collection rate.

[0056] (1-6) In the dust suction device 10 according to any one 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 has a filter placement opening 76 formed by the first side wall section 52a and the partition section 64 for discharging air outside the dust collection container 52, 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 unit 50. This allows the dust suction device 10 to prevent dust from leaking outside the dust collection unit 50 and increase the dust collection rate.

[0058] (1-7) The dust suction device 10 according to any one of (1-1) to (1-6) above comprises 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 passage 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 passage 124.

[0059] By configuring the dust suction device 10 as described above in (1-7), and by 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 through 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 electric 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.

[0061] By configuring the dust suction device 10 as described above in (1-8), the dust collection unit 50 can be used with the dust collection unit 50 firmly locked to 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 Publication No. 2004-283327 discloses an electric vacuum cleaner that generates a suction airflow and collects dust with the generated airflow, and that is composed of a vacuum cleaner main body having a dust case on the main body side that collects and stores dust, and an installation stand having a dust case on the installation stand side that stores dust from the dust case on the main body side, and that when the vacuum cleaner main body is installed on the installation stand, the dust 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 using the suction of a fan motor on the installation stand side.

[0063] Here, in the conventional technology described in the above patent document, dust tends to collect toward the fan motor on the installation stand side, which causes clogging of the ventilation holes in the partition wall upstream of the fan motor, resulting in a decrease in suction performance.

[0064] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a dust suction device that can reduce 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 a device main body 20 having an electric blower 44 that generates suction force, and a dust collection unit 50 that is detachable from the device main body 20 and collects dust sucked from the electric vacuum cleaner 200 by the electric blower 44 in a dust collection container 52, and the dust collection unit 50 has an inlet portion 60, an outlet portion 62 that is provided vertically below the inlet portion 60, and a discharge portion 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 60, the air in the dust collection container 52 flows out from the outlet 62, and the dust in the dust collection container 52 can be disposed of from the outlet 66. The dust collection container 52 has at least a first side wall 52a on which the outlet 62 is provided and a second side wall 52b opposite the first side wall 52a, and the dust collection container 52 is characterized in that it has a partition 64 located above the outlet 62 on the second side wall 52b side relative to the first side wall 52a so as to form a communication section 65 that communicates with the outlet 62.

[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 into the dust collection container 52 from the inlet portion 60 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. This allows the dust suction device 10 to 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 main body 20 having an electric blower 44 that generates suction force, and a dust collection unit 50 that is detachable from the apparatus main body 20 and collects dust sucked from the electric vacuum cleaner 200 by the electric blower 44 in a dust collection container 52, and the dust collection unit 50 has an inlet 60, an outlet 62 provided vertically below the inlet 60, and a discharge unit 66 in the dust collection container 52, and By the suction of the motor-driven blower 44, air flows into the dust collection container 52 from the inlet 60, the air in the dust collection container 52 flows out from the outlet 62, and the dust in the dust collection container 52 can be disposed of from the outlet 66. The dust collection container 52 has at least a first side wall 52a on which the outlet 62 is provided and a second side wall 52b opposite the first side wall 52a, and the outlet 62 is provided at a height equal to or higher than the center position in the vertical direction within the dust collection container 52 or at a position higher than the outlet 66.

[0068] By configuring dust suction device 10 of the present invention as described above in (2-2), dust introduced into dust collection container 52 together with air from inlet 60 is less likely to reach the position where outlet 62 is provided after falling inside dust collection container 52. Therefore, by configuring dust suction device 10 as described above in (2-2), it is possible to reduce a decrease in the suction performance of electric blower 44 caused by dust clogging outlet 62.

[0069] (2-3) In the dust suction device 10 according to (2-1) or (2-1) above, the inlet 60 may be provided in the first side wall 52a, the second side wall 52b, or the upper wall 52e of the dust collection container 52.

[0070] The dust suction device 10 can smoothly introduce the air containing dust into the dust container 52 by being configured as described above in (2-3).

[0071] (2-4) In the dust suction device 10 according to any one of (2-1) to (2-3) above, the partition portion 64 may be bent or curved so that the tip end thereof extends downward.

[0072] By configuring dust suction device 10 as described above in (2-4), dust-containing air introduced into dust collection container 52 can be easily guided to the lower side of outlet 62, and then the air can be guided toward outlet 62. As a result, after the dust introduced into dust collection container 52 together with the air falls inside dust collection container 52, the air in a highly clean state flows out from outlet 62. Therefore, by configuring dust suction device 10 as described above in (2-4), the dust collection rate in dust collection container 52 can be improved, and a decrease in the suction performance of electric blower 44 caused by dust clogging outlet 62 can be reduced.

[0073] (2-5) In the dust suction device 10 according to any one of the above (2-1) to (2-4), the dust collection section 50 preferably has a filter 74 that filters air flowing from the inlet section 60 toward the outlet section 62.

[0074] By configuring the dust suction device 10 as described above in (2-5), the dust suction device 10 can capture dust in the filter 74 and improve the cleanliness of the air discharged from the dust collection unit 50. This allows the dust suction device 10 to improve the dust collection rate in the dust collection container 52.

[0075] (2-6) In the dust suction device 10 according to any one of (2-1) to (2-5) above, the dust collection section 50 has a filter 74 that filters air flowing from the inlet section 60 toward the outlet section 62, the outlet section 62 has an outlet opening 72 for discharging air outside the dust collection container, and the filter 74 is preferably arranged in the outlet opening 72.

[0076] By configuring the dust suction device 10 as described above in (2-6), the filter 74 disposed in the outlet opening 72 can capture dust, thereby improving the cleanliness of the air discharged from the dust collection unit 50. This allows the dust suction device 10 to improve the dust collection rate in the dust collection container 52.

[0077] (2-7) In the dust suction device 10 according to any one of (2-1) to (2-6) 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 has a filter placement opening 76 formed by the first side wall section 52a and the partition section 64 for discharging air outside the dust collection container, and the filter 74 is preferably arranged in the filter placement opening 76.

[0078] By configuring the dust suction device 10 as described above in (2-7), the filter 74 disposed in the filter placement opening 76 can capture dust, thereby improving the cleanliness of the air discharged from the dust collection unit 50. This allows the dust suction device 10 to improve the dust collection rate in the dust collection container 52.

[0079] (2-8) In the dust suction device 10 according to any one of (2-1) to (2-7) above, the filter 74 may be detachably disposed.

[0080] The dust suction device 10 has the above-described configuration (2-8), which allows for appropriate replacement of the filter 74. As a result, cleaning or replacing the filter 74 can ensure the dust capturing ability and ventilation performance of the filter 74.
