  In patent document 1, in order to compress the dust in a dust storage chamber, since a user must operate a compression board with an operation lever, a user's burden is large.

  Therefore, instead of the first filter of Patent Document 1, it is conceivable to provide the dust container of Patent Document 3 so as to open upward. However, in Patent Document 1, the air that has flowed into the dust storage chamber is the lower end of the intake cylinder. Since it is sucked from the opening, the dust accumulated in the dust container of Patent Document 3 is also sucked together with the air from the lower side of the intake cylinder, and as a result, the amount of dust deposited on the first filter in front of the electric blower increases. There is a risk that the suction power will decrease.

  In Patent Document 2, since the separation chamber and the dust container are arranged in parallel, the diameter of the separation chamber and its inner cylinder cannot be increased, and the dust is deposited in the separation chamber as the dust accumulates in the dust container. The contribution of the intake air from the inner cylinder increases, and the pressure loss of the intake air increases. As a result, the suction force may be reduced as compared with the initial state in which no dust is accumulated. Further, in Patent Document 2, since the mesh-like net filter is planar, the user may not be able to easily remove dust stuck to the mesh-like net filter.

  Therefore, it is conceivable to provide the dust container of Patent Document 3 instead of the mesh-shaped net filter of Patent Document 2, but the dust container of Patent Document 3 has a container shape. There is a risk that the shape of the. In addition, when the user holds the handle of Patent Document 2 and opens the rear part of the dust collecting case, the direction of the dust container of Patent Document 3 is the front side (handle) side for the user. There is a risk that the dust inside the container will be caught by the rear part of the dust container of Patent Document 2 and will not be discharged well, and the dust container itself that has jumped out will hit the rear part of the dust container and the dust container itself will not jump out well. is there.

(A) is a perspective view of the state which opened the front cover of the dust accommodating part of the Example of this invention, (B) is the perspective view of the state which opened the rear filter of the dust accommodating part of the Example of this invention. FIG. (A) is the front view seen from the dust accommodating part outer side of the front cover of the dust accommodating part of the Example of this invention, (B) is dust accommodating of the front cover of the dust accommodating part of the Example of this invention. It is the front view seen from the part inside. It is the front view seen from the dust separation part side when the front cover of the dust accommodating part of the Example of this invention is removed. It is a general-view figure of the vacuum cleaner of the Example of this invention.

  In FIG. 1, the cross-sectional view of the cleaner body of the Example of this invention is shown. It is preferable that the vacuum cleaner main body 1 is horizontally placed in the usage state of the vacuum cleaner, and the vacuum cleaner main body 1 is vertically placed in the housed state of the vacuum cleaner. When the vacuum cleaner is in use, if the main body inlet 21 side is the front (upstream side) and the main body exhaust port 30 side is the rear (downstream side), the main body inlet 21 is in the direction of gravity in the housed state of the vacuum cleaner. The main body exhaust port 30 is on the lower side in the direction of gravity action. FIG. 1 is a cross-sectional view of the vacuum cleaner main body 1 when the vacuum cleaner is in use.

  First, the structure of the cleaner body 1 will be described. The dust collector 2 that collects dust from the sucked air is detachably disposed on the front side of the cleaner body 1. When the longitudinal direction (axial direction) of the dust collector 2 is a gravity action direction, the height of the cleaner body 1 is increased. On the other hand, the closer the axial direction of the swirling flow in the dust collector 2 (the axial direction of the dust collecting device 2) is to the gravity acting direction, the greater the separation effect due to the centrifugal separation action, and the axial direction of the swirling flow in the dust collecting device 2 When the angle exceeds 45 ° with respect to the direction of gravity action, the separation effect due to the centrifugal separation action is extremely reduced. Therefore, in order to reduce the height of the vacuum cleaner main body 1 and suppress the decrease in the separation effect due to the centrifugal separation action, in this embodiment, the axial direction of the dust collector 2 is 40 ° to the gravity action direction. It is about 45 °. However, in order to increase the separation effect by the centrifugal separation action, the axial direction of the dust collector 2 may be smaller than 40 ° (for example, 0 °) with respect to the gravity action direction. Instead of disposing the dust separation unit (swivel unit) 4 on the lower side and the dust storage unit 5 on the upper side, the dust separation unit 4 may be disposed on the upper side and the dust storage unit 5 on the lower side. . In this case, the inlet pipe 3 is preferably connected to the circumferential surface of the front end portion in the axial direction of the dust separator 4.

  The dust collector 2 swirls the sucked air and communicates with the dust separator 4 that separates the dust by a centrifugal separation action (cyclone method), and the dust separator 4 accommodates the dust separated by the dust separator 4. A dust container 5 is provided. The dust separator 4 and the dust container 5 are arranged in the axial direction of the dust collector 2 and are connected and communicated with each other in the axial direction. That is, the dust separator 4 is disposed on the front side of the cleaner body 1, and the dust container 5 is disposed on the front side of the cleaner body 1 with respect to the dust separator 4. The dust separator 4 and the dust container 5 are connected so that the user can easily separate the dust separator 4 and the dust container 5. A tubular main body inlet 21 is provided at the front end of the cleaner body 1. A part of the front end face in the axial direction of the dust separator 4 is open, and the opening is connected to the inlet pipe 3. Instead of the front end surface in the axial direction of the dust separator 4, the circumferential surface of the front end in the axial direction of the dust separator 4 may be connected to the inlet pipe 3.

  The dust separation unit 4 includes a hollow substantially cylindrical outer cylinder 6 and a hollow substantially cylindrical inner cylinder 7 enclosed in the outer cylinder 6 with a concentric axis with the outer cylinder 6. When the axial direction of the dust separation part 4 is inclined with respect to the gravity action direction in order to prevent the separation effect due to the centrifugal separation action from deteriorating due to the axial center of the swirling flow being shifted in the gravity action direction by gravity. The axis of the inner cylinder 7 may be shifted downward with respect to the axis of the outer cylinder 6. As shown in FIG. 3A, one end surface (front end surface) in the axial direction of the outer cylinder 6 is closed except for an opening connected to the inlet pipe 3, and the other end surface in the axial direction (rear end surface) of the outer cylinder 6. ) Is open. The outer cylinder 6 is preferably made of transparent or translucent plastic or resin so that dust accumulation can be seen by the user or a sensor provided outside the outer cylinder 6 can detect the accumulation of dust. One end face (front end face) in the axial direction of the inner cylinder 7 is closed, and the other end face (rear end face) in the axial direction of the inner cylinder 7 is open. As shown in FIG. 3A, a recessed portion 8 that is recessed inward in the axial direction of the inner cylinder 7 is formed at the center of the closed portion of one end surface in the axial direction of the inner cylinder 7. The inlet pipe 3 is opposed to the closed portion of one end surface in the axial direction of the inner cylinder 7, that is, the recessed portion 8. As shown in FIG. 3A, a part of the recessed portion 8 reaches the outer peripheral end of the inner cylinder 7. In order to reduce the pressure loss of air, it is preferable that the opening direction of the recessed part 8 is a downward direction. However, the opening direction of the recessed part 8 may be upward or lateral. As shown in FIG. 3A, at the outer peripheral end of the inner cylinder 7 of the recess 8, the recess 8 does not face straight in the radial direction of the inner cylinder 7 but is slightly inclined in the circumferential direction. As shown in FIG. 1, the depth of the recess 8 in the axial direction is about half of the axial length of the cylindrical portion of the inner cylinder 7. However, the axial depth of the recessed portion 8 may extend over substantially the entire axial length of the cylindrical portion of the inner cylinder 7. In this case, the opening of the recessed portion 8 is formed in a part of the circumferential surface of the inner cylinder 7 over almost the entire length of the cylindrical portion of the inner cylinder 7. Further, a guide tube 38 is connected to the outer peripheral end of the recess 8. The cross section of the guide tube 38 has a substantially quarter circle shape, is formed along the outer peripheral surface of the inner cylinder 7, and the outer peripheral surface of the inner cylinder 7 also forms part of the inner wall surface of the flow path. On the outer peripheral surface of the inner cylinder 7, it is formed about several centimeters in the circumferential direction. Therefore, the air that has flowed in the axial direction by the inlet pipe 3 is changed in the radial direction by the recessed portion 8 and further changed in the circumferential direction by the outer peripheral end portion of the inner cylinder 7 of the recessed portion 8. At 38, it can be changed in the circumferential direction. Moreover, it is preferable that the recessed part 8 does not have an unevenness | corrugation and is formed in a curved surface. Thereby, air can be sufficiently swirled while suppressing pressure loss. The guide tube 38 may not be provided. An outer extension 34 extending toward the outer cylinder 6 is formed on the outer periphery of the other axial end surface (rear end face) of the inner cylinder 7. That is, as shown in FIG. 3A, the other axial end surface (rear side end surface) of the inner cylinder 7 has an annular shape with the inner side of the inner cylinder 7 opened.

  As shown in FIG. 3A, a part of the outer extending portion 34 in the circumferential direction is open. With this opening, air outside the inner cylinder 7 can flow into the dust container 5. The inner cylinder 7 is made of an antibacterial metal (for example, silver, copper) or an antibacterial substance (for example, silver, copper) or a coated metal (for example, stainless steel) so as to suppress the growth of bacteria. Preferably it is configured. However, the inner cylinder 7 may be comprised with resin also including a cylindrical part. Then, as shown in FIG. 3A, the outer cylinder 34 is inserted in the axial direction from the other axial end surface of the outer cylinder 6, so that the outer peripheral end of the outer extension 34 comes into contact with the inner periphery of the outer cylinder 6. As a result, the other axial end surface of the outer cylinder 6 is closed. The outer cylinder 6 and the inner cylinder 7 are connected so that the user can easily separate the outer cylinder 6 and the inner cylinder 7. A plurality of through holes 33 are provided on the circumferential surface of the inner cylinder 7. The inner cylinder 7 has a filter function by the plurality of through holes 33. The through-hole 33 allows air to flow from the outer side of the inner cylinder 7 to the inner side of the inner cylinder 7 without large dust flowing into the inner cylinder 7. Although it depends on the suction force, garbage having a weight of 1 yen or more cannot be sucked up in the outer cylinder 6 and may remain in the outer cylinder 6. By connecting the outer cylinder 6 and the inner cylinder 7 so that the user can easily separate the outer cylinder 6 and the inner cylinder 7, the user can easily separate the outer cylinder 6 and the inner cylinder 7 from each other. The dust accumulated in the outer cylinder 6 can be easily discharged, and the hair and lint caught in the through hole 33 of the inner cylinder 7 can be easily removed.

  In order to keep the airtightness of the connecting portion between the dust separator 4 and the dust container 5, a packing 9 is provided on the other axial end surface of the inner cylinder 7. The packing 9 is not only provided on the outer extension 34, but also projects in the axial direction of the inner cylinder 7. Therefore, the inside of the inner cylinder 7 is not completely hollow, and a partially closed space exists due to the packing 9. Further, a recessed portion 39 that is recessed inward in the axial direction of the inner cylinder 7 is formed in a portion of the packing 9 that protrudes to the inner side of the inner cylinder 7. The recess 39 has a handle function. Thereby, the user can hold the dust separation part 4 or the inner cylinder 7 by inserting a finger into the recess 39. A part of the upper side of the extended portion 34 is open and communicates with the outer flow path 35 of the front lid 11. That is, the inside of the outer cylinder 6 and the outside of the cylindrical portion of the inner cylinder 7 communicates with the outer flow path 35 of the front lid 11. As shown in FIG. 3 (A), the circumferential wall surface of the opening on the upper side of the extended portion 34 has a high wall surface on the side facing the opening of the guide tube 38 in the circumferential direction. The wall surface on the opening side of the guide tube 38 is preferably low. For example, assuming that the opening direction of the guide tube 38 is the counterclockwise direction when the dust separation unit 4 is viewed from the front, the left wall surface is high among the circumferential wall surfaces of a part of the upper opening of the extension portion 34, The wall on the right side is low. That is, since a part of the upper side of the extended portion 34 is opened, the circumferential direction of the extended portion 34 is less than one round of the outer periphery of the inner cylinder 7 but is shifted in a spiral shape. Therefore, the swirling flow outside the inner cylinder 7 can collide with the wall surface in the circumferential direction of a part of the opening on the upper side of the extended portion 34 and can smoothly change the direction in the axial direction. Also easily flows to the dust container 5. On the other hand, the inner side of the inner cylinder 7 communicates with the inner flow path 36 of the front lid 11.

  The dust container 5 is provided with a hollow case 10 having an axially one end face (front end face) and an axially other end face (rear end face) that are substantially inverted triangular in cross section. One end surface in the axial direction of the case 10 is closed by a front lid 11 that can be opened and closed. A shaft 31 is provided at the lower end of the front lid 11, and the shaft 31 is supported by the lower end of the case 10. The front lid 11 can be rotated back and forth in the axial direction of the case 10 with the shaft 31 as a fulcrum. A claw projects from the upper end portion of the front lid 11 on the case 10 side. On the other hand, a button 17 (which may be a lever) that can be pressed by the user is provided on the upper front side of the case 10, and a transmission rod (rod) 18 extending to the front side of the case 10 is connected to the button 17. One end of the transmission rod 18 is connected to the button 17, and the other end of the transmission rod 18 is formed in a claw shape. The claw at the other end of the transmission rod 18 can be engaged with the claw at the upper end of the front lid 11. When the front lid 11 is closed to the case 10, it is possible to prevent the front lid 11 from being opened by engaging the claw at the other end of the transmission rod 18 and the claw at the upper end of the front lid 11. When the user presses the button 17, the transmission rod 18 slides forward (may rotate upward), and the engagement between the other end of the transmission rod 18 and the upper end of the front lid 11 is engaged. The combination is released and the front lid 11 can be opened from the case 10 by gravity. While the handle 16 is formed in a horizontal direction, the normal direction of one end surface in the axial direction of the case 10 (corresponding to the front lid 11 portion) is inclined by 45 ° to 50 ° with respect to the horizontal direction. That is, when the user holds the handle 16 and lifts the dust container 5, one end surface in the axial direction of the case 10 (corresponding to the front lid 11 portion) faces downward (the direction of gravity action). Therefore, the front lid 11 can be opened from the case 10 by gravity. As will be described later, if the dust collection basket (dust collection container) 12 is urged by a spring (elastic body) to jump out to the front side of the case 10, the dust collection basket 12 pushes the rear surface of the front lid 11. Therefore, when the user presses the button 17, the front lid 11 can be smoothly opened from the case 10 by the pressing force of the dust collecting basket 12.

  The other axial end surface of the case 10 is closed by a filter 15 that can be opened and closed. A shaft 32 is provided at the lower end of the filter 15, and the shaft 32 is supported by the lower end of the case 10. The filter 15 can be rotated back and forth in the axial direction of the case 10 with the shaft 32 as a fulcrum. The filter 15 is formed with a filter member that is folded in a breez shape within a frame having a substantially square cross-sectional shape. As shown in FIG. 4B, the wave direction of the filter member is preferably the vertical direction (gravity acting direction). The filter 15 is, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). A HEPA filter is an air filter having a particle collection rate of 99.97% or more with respect to particles having a rated air volume of 0.3 μm and an initial pressure loss of 245 Pa or less. A packing 25 may be provided on the surface of the filter 15 opposite to the case 10. The packing 25 can maintain airtightness between the other axial end surface of the dust container 5 and the cleaner body 1 (particularly, the inlet of the intake duct 27). The shaft 31 and the shaft 32 may be shared. Further, the shaft 32 may be provided not at the lower end portion of the filter 15 but at the upper end portion of the filter 15.

  A dust collecting basket 12 is enclosed in the case 10. The shape of the dust collecting basket 12 may be a cage shape, a box shape or a container shape with one surface opened, or a dustpan shape. That is, the dust collecting basket 12 has a shape recessed on the opposite side to the opening. The cross-sectional shape of the dust collecting basket 12 may be a substantially square shape, a substantially circular shape, or a substantially triangular shape. The cross-sectional shape of the dust collecting basket 12 is preferably smaller from the opening surface toward the bottom surface. As a result, the cross-sectional area increases toward the side (opening side) where the dust is discharged, so that the user can easily discharge the dust accumulated in the dust collecting basket 12. The shape of the dust collecting basket 12 is formed by a frame body (support frame). It is preferable that a mesh member made of metal, nylon, or the like is coated or adhered to the bottom surface other than the opening surface of the dust collecting basket 12 and the top, bottom, left, and right surfaces. By providing not only the bottom surface of the dust collecting basket 12 but also the top, bottom, left, and right surfaces, air flow can be secured even if dust accumulates on the bottom surface of the dust collecting basket 12, and the pressure loss of the suction air Can be reduced, and a decrease in suction force can be suppressed. This mesh member is air permeable and has a filter function of collecting dust. A disposable tissue paper may be used instead of the mesh member, or a mesh member and a tissue paper may be combined as long as they are breathable and have a filter function for collecting dust. For example, the user may wear tissue paper on the mesh member. The opening surface of the dust collecting basket 12 coincides with the opening surface of one end surface (front end surface) in the axial direction of the case 10. That is, the opening direction of the dust collecting basket 12 and the opening direction of the one end surface in the axial direction of the case 10 are the same. As shown in FIG. 6, the upper half of the outer peripheral end of the opening surface of the dust collecting basket 12 abuts on the inner peripheral surface of one end surface in the axial direction of the case 10, and the outer peripheral end of the opening surface of the dust collecting basket 12. The lower half is not in contact with the inner peripheral surface of one end surface of the case 10 in the axial direction. The dust collecting basket 12 has a shaft 14 at the bottom. The shaft 14 is supported in the case 10. Therefore, the dust collecting basket 12 can be rotated back and forth in the axial direction of the case 10 with the lower shaft 14 as a fulcrum. Thereby, when the front lid 11 is opened from the dust container 5, a part of the dust collecting basket 12 can be ejected from the dust container 5 by gravity. Since the formation position of the shaft 14 with respect to the case 10 is on the same side (lower side) as the formation position of the shaft 31 with respect to the case 10, the front cover 11 is obstructed when the front cover 11 is opened from the dust container 5. A part of the dust collecting basket 12 can be ejected from the dust container 5 without any trouble. Further, the shaft 14 may be provided with a helical spring in which an elastic force acts in a direction in which the dust collecting basket 12 is pushed out to the front lid 11 side. As a result, when the front lid 11 is opened from the dust container 5, a part of the dust collection basket 12 can jump out of the dust container 5 vigorously by the elastic force of the spring. The dust accumulated in 12 can be easily discharged. Further, the dust collecting basket 12 is divided into two parts in the vertical direction, that is, it is preferably composed of two structures, that is, an upper half frame (support) and a lower half frame (support). The two divided dust collecting baskets 12 are connected by a shaft 13 formed outside the bottom surface of the dust collecting basket 12. Therefore, as shown in FIG. 4 (A), the dust collecting basket 12 has the opening surface of the dust collecting basket 12 split vertically, with the middle of the bottom as a fulcrum. In particular, when a part of the dust collection basket 12 jumps out of the dust container 5, the dust collection basket 12 breaks up and down. As a result, the user can more easily discharge the dust accumulated in the dust collecting basket 12. In particular, dust stuck to the inner surface of the dust collecting basket 12 can be easily removed. However, the upper and lower divided configuration of the dust collecting basket 12 is not essential. In addition, as described above, the front side of the case 10 is inclined by 40 ° to 45 ° with respect to the direction of gravity action, and the dust collection basket 12 jumps out of the dust storage portion 5 by 30 °, so that the dust collection basket 12 Dust accumulated inside can be discharged in the direction of gravity.

  An outer channel 35 and an inner channel 36 penetrating in the axial direction are formed in the front lid 11. The outer flow path 35 is formed on the upper side of the front lid 11, and one end of the outer flow path 35 communicates with the opening of the extended part 34, particularly between the outer cylinder 6 and the inner cylinder 7 of the dust separation part 4. The other end of the outer flow path 35 communicates with the opening of the dust collecting basket 12 in the case 10. In order to prevent the dust accumulated in the dust collecting basket 12 from flowing back to the outer flow path 35 and the dust separation part 4 when the vacuum cleaner is stopped, the other end of the outer flow path 35 is the opening of the dust collecting basket 12. Of these, it is preferable to communicate with the upper half or near the upper end. However, the other end of the outer flow path 35 may communicate with the central portion of the opening of the dust collecting basket 12. Furthermore, in order to prevent the dust accumulated in the dust collecting basket 12 from flowing back to the outer flow path 35 and the dust separator 4 when the vacuum cleaner is stopped, A check valve (not shown) that covers the flow path 35 is preferably formed. The check valve rotates to the dust collecting basket 12 with the upper end as a fulcrum. However, the check valve is not an essential configuration. The cross-sectional area of the outer flow path 35 increases from one end of the outer flow path 35 toward the other end. The formation direction of the outer flow path 35 is a direction from the outer side of the front lid 11 toward the center side from one end of the outer flow path 35 to the other end. That is, the direction is from the outside of the dust collecting basket 12 toward the center side. In order to suppress the turbulence of the air flowing into the dust collecting basket 12 from the outer flow path 35, the outer flow path 35 is formed in the direction of the wall surface (upper wall surface) on the side where the outer flow path 35 of the dust collecting basket 12 communicates. Is preferred. The inner flow path 36 is formed from the center of the front lid 11 to the lower side, and one end of the inner flow path 36 communicates with the other end opening in the axial direction of the inner cylinder 7 (inside the inner cylinder 7) of the dust separator 4; The other end of the inner flow path 36 communicates with the case 10, particularly with the outside of the dust collecting basket 12. The other end of the inner flow path 36 is preferably in communication with the lower outside of the dust collecting basket 12. The inner flow path 36 is formed avoiding the outer flow path 35. Contrary to the outer flow path 35, the cross-sectional area of the inner flow path 36 is reduced from one end of the inner flow path 36 toward the other end.

  A handle 16 that extends in the horizontal direction and can be gripped by the user is provided on the outer side of the upper portion of the dust container 5. The user can hold the handle 16, lift the dust container 5 upward, and remove only the dust container 5 from the cleaner body 1 while leaving the dust separator 4 in the cleaner body 1. In addition, if the dust separation part 4 and the dust storage part 5 are connected, if the user holds the handle 16 and lifts the dust storage part 5 upward, the dust separation part 4 and the dust storage part 5 will be described. And, that is, the dust collector 2 itself can be removed from the cleaner body 1. As shown in FIG. 1, the axial direction other end surface (corresponding to the filter 15 portion) of the dust container 5 is preferably inclined toward the case 10 than the vertical surface (gravity acting direction). That is, it is preferable that the lower part is closer to the case 10 side than the upper part of the other axial end surface of the dust container 5. Moreover, as shown in FIG. 1, the formation direction of the axial direction one end surface (equivalent to front cover 11 part) of the dust accommodating part 5 is about 40 to 45 degrees on the case 10 side from the vertical surface (gravity acting direction). Inclined. That is, the lower part is closer to the case 10 side than the upper part of the one axial end surface of the dust container 5. As a result, the one end surface in the axial direction and the other end surface in the axial direction of the dust container 5 have an inverted C shape with respect to the vertical surface (gravity acting direction). Thereby, when a user lifts the dust accommodating part 5 upward, it becomes less caught, and the user can easily remove the dust accommodating part 5 from the cleaner body 1. Then, the user can easily remove the dust separator 4 from the cleaner body 1 by holding the recess 39 and lifting the dust separator 4 upward or obliquely upward after removing the dust container 5. As shown in FIG. 1, it is preferable that the axial direction other end surface (corresponding to the inlet pipe 3 portion) of the dust separation portion 4 is inclined toward the outer cylinder 6 side than the vertical surface (gravity acting direction). That is, it is preferable that the lower part is closer to the outer cylinder 6 side than the upper part of the other axial end surface of the dust separator 4. As a result, when the user lifts the dust separator 4 upward or obliquely upward, there is less catching, and the user can easily remove the dust separator 4 from the cleaner body 1. Further, not only when the user removes the dust separator 4, but also when the dust separator 4 and the dust container 5 are integrated, that is, when the dust collector 2 itself is removed from the cleaner body 1. Since the one end surface in the axial direction and the other end surface in the axial direction have an inverted C shape with respect to the vertical surface (the direction of gravity action), the user is less likely to be caught when lifting the dust collector 2 upward. Can easily remove the dust collector 2 from the cleaner body 1.

  A hose joint pipe 20 is inserted into the main body inlet 21 and can hold the hose joint pipe 20. A packing 22 is provided at one end of the main body inlet 21. Thereby, the airtightness of the hose joint pipe 20 and the inlet pipe 3 can be maintained. A caster support portion 23 for supporting casters is provided at the front lower end of the vacuum cleaner body 1 (below the dust collector 2). An intake duct 27 extending in the front-rear direction of the cleaner body 1 is provided on the upper rear side in the cleaner body 1. An opening at one end in the extending direction of the intake duct 27 faces the filter 15. An auxiliary filter 26 is provided near the opening at one end of the intake duct 27. Thereby, it is possible to suppress the electric blower 28 from sucking the dust remaining outside the dust collector 2. The other end in the extending direction of the intake duct 27 is closed, and the lower portion near the other end in the extending direction of the intake duct 27, that is, the electric blower 28 side is opened. A dust removing device 24 that removes dust adhering to the filter 15 is provided at a position in contact with the filter 15 at an upper portion of one end of the intake duct 27 of the cleaner body 1. The dust removing device 24 includes a spiral spring (elastic body) on the outer periphery of the rotating body. The dust removing device 24 is rotated by a motor or by pulling out a cord reel, and a spiral spring repels a filter member of the filter 15 to shake off dust attached to the filter 15. As described above, since the wave direction of the filter 15 is the vertical direction, the dust that has been shaken off easily falls in the direction of gravity. The dust shaken off from the filter 15 accumulates in the case 10. Accordingly, clogging of the filter 15 can be suppressed, a decrease in air pressure loss can be suppressed, and a decrease in suction force can be suppressed. An electric blower 28 that generates a suction force is provided on the lower rear side in the cleaner body 1. The electric blower 28 is installed vertically so that the suction port of the electric blower 28 faces upward. An exhaust duct 40 communicating with the exhaust port of the electric blower 28 is provided on the downstream side of the electric blower 28 and on the front side of the electric blower 28. Further, a filter 29 communicating with the exhaust duct 40 is provided on the downstream side of the exhaust duct 40 and on the front side of the exhaust duct 40. The filter 29 is formed with a filter member that is folded in a breez shape within a frame having a substantially square cross-sectional shape. The wave direction of the filter member is preferably the longitudinal direction (gravity acting direction). The filter 15 is, for example, a high-density ULPA filter (Ultra Low Penetration Air Filter). The ULPA filter is an air filter having a particle collection rate of 99.9995% or more with respect to particles having a rated air volume of 0.15 μm and an initial pressure loss of 245 Pa or less. The particle collection efficiency is higher than the collection efficiency. And the main body exhaust port 30 is provided in the rear-end surface of the cleaner body 1. FIG.

  Next, the flow of air during operation (when in use) of the vacuum cleaner will be described. The arrows in FIG. 1 indicate the flow of air. When the user turns on the power of the vacuum cleaner, the electric blower 28 operates and generates a suction force. The air sucked from the hose joint pipe 20 flows into the outer cylinder 6 through the inlet pipe 3, hits the dent portion 8, changes its direction in the radial direction, and further, the outer periphery of the inner cylinder 7 of the dent portion 8. The direction is slightly changed in the circumferential direction at the end, and the direction is further changed in the circumferential direction by the guide tube 38. As a result, air turns around the outer cylinder 6 about the axis of the outer cylinder 6. That is, it becomes a swirl flow. The heavy dust contained in the air collects outside the swirling flow by the centrifugal separation action accompanying the swirling of the air. Light dust contained in the air remains not only outside the swirl but also inside. However, in general household cleaning, most of the dust collects outside the swirling flow, and much dust does not remain inside the swirling flow. The air outside the inner cylinder 7 flows into the dust collecting basket 12 through the outer flow path 35 together with heavy dust. The dust is collected by the dust collecting basket 12, accumulated, and further compressed by the suction force. Since the dust is automatically compressed by the suction force, a lot of dust can be held without bothering the user. The air passes through the bottom surface and the top, bottom, left and right surfaces of the dust collecting basket 12 and reaches the filter 15. On the other hand, the swirling inner air flows into the inner cylinder 7 from the through hole 33 of the inner cylinder 7. Dust larger than the through hole 33 cannot pass through the through hole 33 and remains outside the inner cylinder 7. The air in the inner cylinder 7 together with light dust and small dust flows through the inner flow path 36 and flows into the lower outside of the dust collecting basket 12 in the case 10 and reaches the filter 15. The air that has passed through the dust collecting basket 12 and the air that has not passed through the dust collecting basket 12 merge before the filter 15 and pass through the filter 15. The filter 15 collects light dust, small dust, and other dust contained in the air. Air that passes through the filter 15 and contains almost no dust flows through the auxiliary filter, flows into the intake duct 27, passes through the opening at the lower portion of the intake duct 27, and is sucked from the suction port at the upper portion of the electric blower 28. The air discharged from the discharge port on the side of the electric blower 28 reaches the filter 29 through the exhaust duct 40, and the dust remaining by the filter 29 is collected. The air that has passed through the filter 29 passes through the electric blower 28, the cord reel chamber (not shown), the gap at the bottom of the cleaner body 1, and the like, and is discharged from the body exhaust port 30 to the outside of the cleaner body 1. . In particular, since the filter 29 has a dust collection efficiency equivalent to or higher than that of a filter mounted on the air cleaner, the air discharged from the cleaner body 1 to the outside is equivalent to or higher than that of the air cleaner. Has been cleaned. FIG. 2A shows a perspective view of the dust collector of the embodiment of the present invention, and FIG. 2B shows a cross-sectional view of the dust collector of the embodiment of the present invention. The user can remove the dust collector 2 from the cleaner body 1 by holding the handle 16 and lifting the dust collector 2 upward. However, the dust separator 4 may be left in the cleaner body 1 and only the dust container 5 may be removed from the cleaner body 1. As shown in FIG. 2A, the outer shape of the cross section of the dust separation portion 4 viewed from the axial direction is a substantially circular shape. The outer shape of the cross section of the dust container 5 is substantially circular at the front lid 11, but is substantially square after the front lid 11, and is also substantially square at the filter 15. As shown in FIG. 2B, the opening direction at one axial end of the case 10 and the opening direction at the other axial end of the case 10 are not in a straight line and differ by about 45 ° to 50 °. That is, the axial direction of the dust container 5 is bent slightly forward from the middle. As described above, one end surface in the axial direction of the dust collector 2 (portion of the inlet pipe 3) faces slightly downward (the direction of gravity action), and the other end surface in the axial direction of the dust collector 2 (portion of the filter 15) is also , Slightly facing downward (gravity acting direction), one end surface in the axial direction and the other end surface in the axial direction of the dust collector 2 have an inverted C shape with respect to the vertical surface (gravity acting direction). Therefore, when the dust collector 2 is lifted upward, the amount of catch is reduced, and the user can easily remove the dust collector 2 from the cleaner body 1.

  FIG. 3A shows a perspective view of the inner cylinder and the outer cylinder of the embodiment of the present invention, and FIG. 3B shows a perspective view of the back side of the inner cylinder of the embodiment of the present invention. One end surface of the outer cylinder 6 is closed except for a portion where the inlet pipe 3 is formed, and the other end surface of the outer cylinder 6 is opened. The inner cylinder 7 has an annular extending portion 34 at one end of the cylindrical portion. As shown in FIG. 3A, the outer peripheral end of the other end surface of the outer cylinder 6 abuts on the outer peripheral end of the outer extension part 34 by being inserted into the outer cylinder 6 from the cylindrical portion of the inner cylinder 7 in the axial direction. Thus, the inner cylinder 7 is formed in the outer cylinder 6. As shown in FIG. 3A, the opening direction of the inlet pipe 3 and the opening of the recessed portion 8 are opposed to each other. The opening direction of the recess 8 toward the outer peripheral end of the inner cylinder 7 is substantially downward, and the opening direction of the guide tube 38 in the circumferential direction is counterclockwise. The circumferential opening direction of the guide tube 38 may be clockwise. And the hole penetrated to an axial direction is provided in the upper part of the outward extension part 34, ie, the upper part of the outward extension part 34 is opening. The left wall surface of the opening is higher than the right wall surface. That is, the wall surface (left wall surface) of the upper opening of the extension part 34 facing the opening direction in the circumferential direction of the guide tube 38 is higher than the other wall surface (right wall surface). The surface of the extended portion 34 is spiral, and has a function of a flow path that smoothly guides air to the opening above the extended portion 34. As shown in FIG. 3 (B), the upper substantially semicircular portion in the inner cylinder 7 is provided with a recessed portion 39 that is recessed toward the inner side of the inner cylinder 7, and the lower substantially semicircular portion is formed in the inner cylinder 7. Open in. When the flow rate of air outside the inner cylinder 7 is made larger than the flow rate of air inside the inner cylinder 7 in a state where dust is not accumulated in the dust collecting basket 12, the upper portion of the extended portion 34 is higher than the opening area inside the inner cylinder 7. The opening area may be increased. The area of the recessed portion 39 may be increased as compared with the opening into the inner cylinder 7, or the area of the opening into the inner cylinder 7 may be increased as compared with the recessed portion 39. Then, the user can easily hold the dust separation part 4 or the inner cylinder 7 by putting his / her finger into the recess 39.

  When the cylindrical portion of the inner cylinder 7 is formed of a metal material having an antibacterial effect, first, a plurality of through-holes 33 having a diameter of about 0.1 mm to 0.4 mm are etched into a thin metal plate, and then both ends are formed. Join into a cylindrical shape. The through hole 33 may be punched. Examples of the metal material having an antibacterial effect include stainless steel, silver, and copper. The alloy is not limited to stainless steel, silver and copper, and may be any alloy containing silver or copper or having silver or copper surface-deposited. The thickness of the metal thin plate is 1 mm or less, and about 0.1 mm to 0.5 mm is preferable for improving workability. When the metal thin plate is thin, it is preferable to fix both ends in the axial direction of the cylindrical metal thin plate with a resin having good formability in order to improve the strength and the roundness. Specifically, a substantially circular one-end mold of the inner cylinder 7 having the recessed portion 8 and the guide tube 38 and a mold of the other end of the inner cylinder 7 having the annular outer extension 34 are formed into a molded mold. Then, a cylindrical metal thin plate is set, and then insert molding is performed by pouring resin into a mold. In the case of insert molding, the metal thin plate may not be formed into a cylindrical shape by joining both ends. Thus, only the cylindrical portion of the inner cylinder 7 in which the substantially circular one end portion of the inner cylinder 7 having the recessed portion 8 and the guide tube 38 and the other end portion of the inner cylinder 7 having the annular outer extending portion 34 are made of resin. Can be made of a metal material. Insert molding can simplify the manufacturing process.

  FIG. 4 (A) shows a perspective view of a state where the front cover of the dust container of the embodiment of the present invention is opened, and FIG. 4 (B) shows the rear filter of the dust container of the embodiment of the present invention opened. FIG. As shown in FIG. 4A, when the front lid 11 is pivoted downward with the shaft 31 as a fulcrum, the dust collecting basket 12 is also pivoted downward with the shaft 14 as a fulcrum. At this time, the dust collecting basket 12 is divided into two parts up and down with the shaft 13 as a fulcrum. The opening of the dust collection basket 12 when it jumps out of the dust storage section 5 is wider than the opening of the dust collection basket 12 stored in the dust storage section 5. As a result, the dust stuck to the inner surface of the dust collecting basket 12 can be easily removed. When the user attaches the tissue paper along the inner surface of the dust collecting basket 12, the end of the tissue paper is sandwiched between the frame of the opening of the dust collecting basket 12 and the outer peripheral end of the front lid 11. In this case, the tissue paper can be prevented from shifting or coming off. As shown in FIG. 4B, the filter 15 is also rotated downward and opened with the shaft 32 as a fulcrum. As a result, the user can easily discharge the dust accumulated outside the dust collecting basket 12 in the case 10, and can easily remove the dust attached to the side surface of the case 10 of the filter 15.

  FIG. 5A is a front view of the front cover of the dust container of the embodiment of the present invention as viewed from the outside of the dust container, and FIG. 5B is a front view of the dust container of the embodiment of the present invention. It is the front view seen from the dust accommodating part of a lid | cover. The hatched portion in the figure shows the frontmost surface, not the cross section. A shaft 31 that is rotatably supported by the case 10 is provided at the lower end of the front lid 11. The front lid has a substantially circular shape. A substantially circular portion outside the shaded portion shown in FIG. 5A can contact the outer peripheral end of the other end surface in the axial direction of the dust separation portion 4. A substantially circular portion inside the hatched portion shown in FIG. 5A can contact the outer peripheral end of the other axial end surface of the inner cylinder 7 of the dust separating portion 4. On the upper side of the front lid 11, that is, on the side opposite to the shaft 31, an opening of the outer flow path 35 is formed between a substantially circular portion outside the shaded portion and a substantially circular portion inside. The opening position on the front side (outside of the dust container 5) of the outer channel 35 may be the left and right sides or the lower side of the front lid 11, but the opening position on the back side (inside the dust container 5) of the outer channel 35 is the front cover. 11, the opening position on the front side of the outer flow path 35 is also preferably above the front lid 11 in order to reduce the pressure loss of the air by reducing the length of the outer flow path 35. . On the other hand, an opening of the inner flow path 36 is formed inside the inner cylinder 7. In the front view of FIG. 5A, the opening area of the inner flow path 36 is larger than the opening area of the outer flow path 35, but the upper semicircular portion in the inner cylinder 7 has a recess 39. Therefore, when the flow rate of air outside the inner cylinder 7 is made larger than the flow rate of air inside the inner cylinder 7, the substantial flow path area is that the opening of the inner flow path 36 is larger than the opening area of the outer flow path 35. The area is smaller. A portion where the opening of the outer flow path 35 between the substantially circular portion outside the shaded portion and the inner substantially circular portion is not formed is closed. A substantially circular portion outside the shaded portion shown in FIG. 5B abuts on the outer peripheral end of the axial end surface of the case 10 and a part of the outer peripheral end of the opening of the dust collecting basket 12. As shown in FIG. 5B, the opening of the outer flow path 35 is formed above the vertical center line of the front lid 11. Thereby, when the vacuum cleaner is stopped, it is possible to prevent the dust accumulated in the dust collecting basket 12 from flowing back to the outer flow path 35 and the dust separator 4. However, the opening of the outer flow path 35 may be formed in the center portion including the vertical center line of the front lid 11. Furthermore, it is preferable to form a check valve (not shown) that covers the outer flow path 35. This further prevents the dust accumulated in the dust collecting basket 12 from flowing back to the outer flow path 35 and the dust separator 4 when the vacuum cleaner is stopped. On the other hand, an opening of the inner flow path 36 is formed near the lower end of the front lid 11. However, the opening position of the inner flow path 36 may be lower than the opening position of the outer flow path 35, or may be on the left or right side or the upper side. The hatched portion on the upper side of the opening of the inner flow path 36 contacts the lower end of the outer peripheral end of the opening of the dust collecting basket 12. Then, as shown in FIG. 5B, the opening area of the outer flow path 35 is larger than the opening area of the inner flow path 36 on the back side of the front lid 11 (inside the dust container 5). Furthermore, as shown in FIGS. 5A and 5B, the opening area (FIG. 5B) of the other end (back side) of the outer flow path 35 is equal to that of one end (front side) of the outer flow path 35. It is larger than the opening area (FIG. 5A). That is, the outer flow path 35 extends from one end to the other end. On the other hand, as shown in FIGS. 5 (A) and 5 (B), the opening area (FIG. 5 (B)) of the other end (back side) of the inner flow path 36 is equal to that of one end (front side) of the inner flow path 36. It is smaller than the opening area (FIG. 5A). That is, the inner flow path 36 is narrowed from one end to the other end.

  FIG. 6 is a front view as seen from the dust separation unit side when the front cover of the dust container of the embodiment of the present invention is removed. As in FIG. 5, the hatched portion in the figure indicates the frontmost surface, not the cross section. The substantially circular shaded portion is in contact with the outer peripheral end of the front lid 11. As shown in FIG. 6, the outer peripheral end of the opening on one end surface in the axial direction of the case 10 abuts a part of the outer peripheral end of the opening of the dust collecting basket 12. As shown in FIG. 6, 80% or more of the opening on one end surface in the axial direction of the case 10 is occupied by the opening of the dust collecting basket 12. A region other than the opening of the dust collection basket 12 in the opening of the case 10 (the remaining 20% or less) faces the opening of the inner flow path 36 and communicates with the inner flow path 36.

  FIG. 7 is a schematic view of a vacuum cleaner according to an embodiment of the present invention. In addition to the vacuum cleaner main body 1, the vacuum cleaner includes a suction tool 50 having a suction port, one end communicating with the suction tool 50, a telescopic joint pipe (extension pipe) 51, and one end communicating with the other end of the joint pipe 51. An operation tube 52 having a handle 53 and an operation button / switch that are gripped by the user, and a hose 54 having one end communicating with the other end of the operation tube 52 and the other end forming the hose coupling tube 20 are provided. The hose joint pipe 20 is inserted into the main body inlet 21 of the cleaner body 1 and can be held. Further, wheels 55 are provided on both side surfaces of the cleaner body 1. And if the power supply of a vacuum cleaner is turned ON by operation to an operation button / switch from a user, the electric air blower 28 will act | operate and will generate | occur | produce suction | attraction force. The air sucked from the suction port of the suction tool 50 passes through the joint pipe 51, the operation pipe 52, the hose 54, and the hose joint pipe 20 in this order, and flows into the cleaner body 1.

  According to the embodiment of the present invention, dust can be compressed without bothering the user, the user can easily discharge the dust that has been compressed and accumulated, and a reduction in suction force can be suppressed.

  The present invention is applicable to a vacuum cleaner.
