Description

  The present invention relates to a vacuum cleaner.

  A general vacuum cleaner includes a main body provided with an electric blower, a suction part that is moved along the floor surface, and a connection hose that connects the suction part to the main body. A disposable filter can be attached. When this type of vacuum cleaner is operated, the outside of the machine (air on the floor) is sucked from the suction part by the drive of the electric blower provided in the body, and the air passes through the connection hose to the body. It is sucked into the main body from the suction port formed in the. The inlet of the disposable filter accommodated in the body communicates with the suction port, and when the air sucked from the suction port passes through the disposable filter, dust contained in the air is captured by the disposable filter (for example, , See Patent Document 1).

  However, this type of vacuum cleaner is uneconomical because it uses a disposable filter and is not preferable from the viewpoint of environmental protection. Further, since the disposable filter is not replaced until a certain amount of dust is accumulated in the filter, there is a problem that bad odor is generated from the accumulated dust or the like, and the suction force is reduced as the dust is accumulated, and the dust collection efficiency is deteriorated.

Recently, there has been known an electric vacuum cleaner equipped with a swirling dust collector that can swirl the air sucked from the suction port to separate and capture the dust contained in the air by centrifugal force. . The dust accumulated in the swivel dust collector can be easily removed by removing the dust collector from the main body and performing a predetermined operation. In vacuum cleaners that use a swirling dust collector, the dust collected in the swirling dust collector is frequently removed (for example, every time cleaning is performed), thereby reducing the generation of bad odors and reducing dust collection efficiency. There is an advantage that it can be prevented.

And a leg member (65) for standing and holding the dust collector together with the mounting part on the floor surface is formed on the lower surface of the casing. The vacuum cleaner is characterized in that the dust collector is formed at a height in which the inlet of the dust collector is substantially horizontal or upward in a state where the dust collector is erected and held.

  The alphanumeric characters in parentheses represent corresponding components in the embodiments described later. The same applies hereinafter.

  According to this configuration, even when the swivel dust collector is removed from the vacuum cleaner and placed on the floor when cleaning the swirl dust collector, it is formed by extending a part of the bonding rib. Accordingly, the swivel type dust collector can be prevented from falling down and spilling out dust accumulated therein. Further, since the leg member is formed in a height in which the entrance of the dust collector is substantially horizontal or upward with the dust collector standing and held, a swivel dust collector using the leg member and the mounting portion is used. It is possible to prevent dust accumulated in the swivel type dust collector from spilling out from the inlet in a state where the is vertically held. Therefore, it is possible to further improve the workability when removing the dust accumulated in the swivel type dust collector.

  According to the second aspect of the present invention, the air sucked from the suction port (104) can be swirled so that dust contained in the air can be separated and captured by centrifugal force, and the air after the dust is captured. A vacuum cleaner (101; 101A; 101B; 101C) equipped with a swirling dust collector (107) that discharges air from the exhaust port, wherein the swirling dust collector is air sucked from an inlet (50) A hollow casing (52) that can be swiveled inside, and a filter for capturing the dust contained in the air by passing the air discharged from the exhaust port (53) formed in the rear surface of the casing (54) and a filter holding member (55) for holding the filter, and a fixing part (5) for rotatably fixing the filter holding member on both the left and right sides of the lower surface of the casing. ) And a leg member (65) for standing and holding the dust collector on the floor surface together with the fixed portion is formed on the lower surface of the casing, and the leg member is used to stand the dust collector. The vacuum cleaner is characterized in that the inlet of the dust collector is formed in a horizontal direction or a height facing upward in a state where the dust collector is held.

  According to this configuration, even when the swivel dust collector is removed from the vacuum cleaner and placed on the floor when cleaning the swirl dust collector, it is formed by extending a part of the bonding rib. Therefore, the swiveling dust collector can be prevented from falling down and spilling out dust accumulated therein. In addition, the leg member is formed at a height in which the entrance of the dust collector is substantially horizontal or upward with the dust collector standing and held, so that the swivel type dust collector using the leg member and the fixing portion is used. It is possible to prevent dust accumulated in the swivel type dust collector from spilling out from the inlet in a state where the is vertically held. Therefore, it is possible to further improve the workability when removing the dust accumulated in the swivel type dust collector.

  The invention according to claim 3 is characterized in that a cleaning tool (66) usable when cleaning the dust collector (107) is held on the rear surface of the leg member (65). It is a vacuum cleaner as described in.

  According to this configuration, since the cleaning tool is not held on the wall surface of the dust collecting chamber but is held on the dust collecting device, when the disposable filter is mounted, the cleaning is performed by holding the disposable filter on the wall surface of the dust collecting chamber. It is possible to prevent harmful effects such as damage due to contact with tools.

  Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a cross-sectional view of the electric vacuum cleaner 1 according to the first embodiment of the present invention as viewed from the right side when the electric vacuum cleaner 1 is cut along a vertical plane along the front-rear direction. FIG. 2 is a cross-sectional view of the electric vacuum cleaner 1 as viewed from above when the electric vacuum cleaner 1 is cut along a horizontal plane. The description will be made assuming that the left side in FIG. 1 is the front, the right side is the rear, the upper side in FIG. 2 is the left side, and the lower side is the right side.

  Referring to FIGS. 1 and 2, this vacuum cleaner 1 includes a main body 3 provided with an electric blower 2 and a connection hose 5 having one end inserted into a suction port 4 formed at the front end of the main body 3. (In FIG. 2, the connection hose 5 is omitted). The connection hose 5 is a long tubular member at least part of which is formed in a bellows shape, and a suction portion is attached to the other end (not shown). When cleaning is performed, the dust blower on the floor surface is sucked together with the air from the suction portion by moving the suction portion along the floor surface while the electric blower 2 provided in the main body 3 is driven. Air sucked from the suction portion flows into the main body 3 from the suction port 4 through the connection hose 5. A plurality of wheels 6 are attached to the lower part of the main body 3, and the main body 3 can be moved along the floor surface by rolling these wheels 6 along the floor surface. Yes.

  The vacuum cleaner 1 is equipped with a swiveling dust collector 7 for swirling the air sucked from the suction port 4 to separate and capture dust contained in the air by centrifugal force. Can be done. A blower housing chamber 8 for housing the electric blower 2 is formed on the rear side in the main body 3, and a dust collection chamber 9 for housing the dust collecting device 7 is formed on the front side in the main body 3. The electric blower 2 is arranged in a space of about two-thirds on the right side in the blower housing chamber 8, and the space on the left third in the blower housing chamber 8 is supplied with electric power from the outside to the vacuum cleaner 1. The cord accommodating part 11 which accommodates the power cord 10 for supplying this is formed. A cord winding wheel 12 is disposed in the cord housing portion 11 so as to be rotatable about a rotary shaft 12A extending in the left-right direction. When the electric vacuum cleaner 1 is not used, the power cord 10 is connected to the cord winding wheel 12. It can be accommodated in the cord accommodating part 11 in the state wound around the outer peripheral surface.

  The upper surface of the dust collection chamber 9 is opened, and the upper surface opening can be covered with the dust cover 13. A substantially circular opening 14 communicating with the suction port 4 is formed in the front wall 9 </ b> A that partitions the front surface of the dust collection chamber 9. The opening 14 is formed to be slightly upward with respect to the vertical plane, that is, to be inclined forward as it goes upward. An air inlet 15 into the dust collecting chamber 9 is formed in a substantially circular shape on the front surface of the dust collecting device 7, and a cylindrical inlet pipe 16 projects from the inlet 15 toward the front. The front end edge of the inlet pipe 16 is formed so as to be inclined forward as it goes upward corresponding to the inclination of the opening 14. The dust collector 7 is inserted into the dust collecting chamber 9 from above through the upper surface opening with the dust cover 13 opened. By making the front end edges of the opening 14 and the inlet pipe 16 inclined with respect to the vertical plane as described above, even when the dust collector 7 is inserted into the dust collecting chamber 9 vertically downward, the opening 14 Can be prevented from interfering with the peripheral edge of the inlet pipe 16. A substantially annular packing 17 is attached to the peripheral edge of the opening 14, and the front end edge of the inlet pipe 16 is pressed against the packing 17 in a state where the dust collecting device 7 is housed in the dust collecting chamber 9. Thus, the gap between the opening 14 and the front end edge of the inlet pipe 16 is sealed.

  The dust collector 7 is made of, for example, resin and has a hollow casing 18 inside which air can be swirled, and air discharged from an exhaust port 19 formed on the rear surface of the casing 18. The filter 20 for capturing dust contained in the air and the filter holding member 18B that surrounds and holds the outer periphery of the filter 20 are provided. The filter 20 is made of a material containing urethane, for example.

  The inlet 15 is formed on the front surface of the casing 18, and the inlet pipe 16 protrudes forward from the inlet 15. A swirl passage 21 is defined in the casing 18 by a partition wall. More specifically, the air that has entered the casing 18 from the inlet 15 swivels clockwise around the swirl axis 22 (see FIG. 2) as viewed from the front side along the swirl passage 21. It has become. The end portion of the swirl flow path 21 communicates with a dust collection portion 23 that extends immediately upstream (immediately forward) of the exhaust port 19.

  Dust contained in the air that has flowed into the casing 18 from the inlet 15 in the process of swirling along the swirl flow path 21 is caused to act outwardly in the swirl flow path 21 (with respect to the swirl axis 22 by the action of centrifugal force). (Radially outward side). A substantially cylindrical filter 24 (see FIG. 2) is disposed in the casing 18 along the turning axis 22. The filter 24 is, for example, a mesh filter formed by connecting metal wires in a lattice shape. The rear end of the filter 24 faces the upstream side of the exhaust port 19 in the dust collecting portion 23. With such a configuration, the dust contained in the air swirling along the swirl flow path 21 swirls outward in the swirl flow path 21, and thus is guided to the dust collection unit 23 without passing through the filter 24. However, a part of the air swirling on the inner side (the swirl axis 22 side) in the swirling flow path 21 (air from which dust has been separated) passes through the filter 24 and passes through the filter 24. It is led to the upstream side of the exhaust port 19. Therefore, the dust contained in the air flowing into the casing 18 from the inlet 15 can be separated by the centrifugal force and captured by the dust collecting unit 23, and the air from which the dust has been separated is exhausted through the filter 24 through the exhaust port 19. Since it can guide to the side, dust can be captured well.

  FIG. 3 is a perspective view of the filter holding member 18 </ b> B viewed from diagonally upward on the front side. FIG. 4 is a perspective view showing a state in which the filter holding member 18B and the filter 20 held by the filter holding member 18B are cut along a horizontal plane.

  Referring to FIGS. 3 and 4, filter holding member 18 </ b> B is made of, for example, a resin, and has a substantially rectangular rear plate portion 25 and an annular shape that protrudes forward along the outer peripheral edge of rear plate portion 25. The side plate portion 26 is integrally formed. The filter 20 is fitted into the filter holding member 18B so that the outer peripheral surface thereof is along the inner peripheral surface of the annular side plate portion 26. When the filter 20 is fitted into the filter holding member 18B, the front surface thereof is the front edge of the annular side plate portion 26. It becomes almost the same. A positioning projection 27 is formed on the inner peripheral surface (the lower left corner) of the annular side plate portion 26, and a recess 28 is formed at a position corresponding to the positioning projection 27 of the filter 20 (the lower left corner). Has been. Therefore, by fitting the filter 20 into the filter holding member 18B so that the positioning projection 27 enters the recess 28, the filter 20 can be mounted without making a mistake in the front / back and top / bottom / left / right orientations.

  At both left and right end portions of the lower end edge of the annular side plate portion 26, attachment portions 29 for attaching the filter holding member 18B to the casing 18 so as to be rotatable are formed. In addition, an operation unit 30 is formed to project at the center in the left-right direction of the upper end edge of the annular side edge 26. When removing dust accumulated in the dust collector 7 (in the casing 18), the dust cover 7 is opened and the dust collector 7 is extracted from the dust chamber 9, and then the operation unit 30 is pulled backward. Thus, the inside of the casing 18 can be opened by rotating the filter holding member 18B around the mounting portion 29. In this state, the dust in the casing 18 can be easily removed, and the dust attached to the filter 20 can be removed by removing the filter 20 from the filter holding member 18B.

  A substantially rectangular opening 31 is formed in the rear plate portion 25 of the filter holding member 18B, and a plurality of bar members (vertical ribs 32A) extending in the vertical direction and a plurality of bars extending in the left-right direction are formed in the opening 31. Are arranged in a lattice shape, thereby forming a plurality of ventilation holes for allowing air discharged from the exhaust port 19 through the filter 20 to pass therethrough. The front surface of each horizontal rib 32B projects forward from the front surface of each vertical rib 32A. In addition, an annular rib (a peripheral rib 32 </ b> C) that protrudes forward is formed at the peripheral edge of the opening 31. The front surface of the peripheral rib 32C projects forward from the front surface of each lateral rib 32B. With such a configuration, in a state where the filter 20 is fitted into the filter holding member 18B, the front surface of each lateral rib 32B abuts on the rear surface of the filter 20, and the peripheral rib 32C bites into the peripheral portion of the rear surface of the filter 20. It has become. In this state, the rear surface of the filter 20 and the vertical rib 32A are separated from each other with a predetermined interval (for example, about 6 mm).

  Referring to FIGS. 1 and 2 again, when the dust collector 7 is inserted into the dust collection chamber 9, the rear surface of the filter holding member 18 </ b> B comes into contact with the rear wall 9 </ b> B that defines the rear surface of the dust collection chamber 9. The portion from the center portion of the rear wall 9B to the right side (the portion of the blower housing chamber 8 that faces the space where the electric blower 2 is disposed) has a smaller area than the area of the filter 20 (the exhaust port 19). A substantially rectangular opening 33 is formed. The opening 33 communicates the dust collection chamber 9 and the blower housing chamber 8, and faces the suction port 2 </ b> A of the electric blower 2 disposed in the blower housing chamber 8. For example, the opening 33 is covered with a filter 34 having a pleated structure in which filter papers are arranged in a bellows shape.

  In this embodiment, the dust collector 7 (casing 18) is made as large as possible (from the left end of the dust collection chamber 9) in order to improve the dust collection efficiency by favorably swirling the air sucked from the suction port 4 of the main body 3. The exhaust port 19 is formed larger (over the entire rear surface of the dust collector 7) in order to discharge the air from the dust collector 7 well. If the exhaust port 19 is formed larger, the filter 20 covering the exhaust port 19 can be formed larger, so that clogging of the filter 20 can be suppressed.

  On the other hand, a space (for example, a cord winding wheel 12) for arranging other parts other than the electric blower 2 is arranged in the blower housing chamber 8 adjacent to the rear side of the dust collecting chamber 9 with the rear wall 9B interposed therebetween. Therefore, the opening 33 formed in the rear wall 9B is inevitably formed smaller than the exhaust port 19. In such a case, air flows favorably from the portion facing the opening 33 to the opening 33 through the filter 20 in the entire exhaust port 19, but air circulation in the portion not facing the opening 33 is performed. It gets worse.

  In this embodiment, by separating the rear surface of the filter 20 and the vertical rib 32A, air exhausted through the filter 20 from a portion not facing the opening 33 of the exhaust port 19 is guided to the opening 33 side. The guide path 35 is formed. Therefore, since the air passage in the part which does not oppose the opening 33 of the exhaust port 19 can be ensured by the guide path 35, the fall of suction force is suppressed and dust collection efficiency improves.

  Particularly, since the rear surface of the filter holding member 18B is in contact with the rear wall 9B, the dust collecting device 7 can be firmly fixed in the dust collecting chamber 9 and formed between the vertical rib 32A and the filter 20. The guide path 35 can be configured by the space formed.

  In addition, by causing the peripheral rib 32C formed on the filter holding member 18B to bite into the rear surface of the filter 20, it is possible to prevent a gap from being generated between the peripheral edge of the filter 20 and the filter holding member 18B. Therefore, the peripheral rib 32C serves as a wall, so that it is possible to prevent the dust from leaking from the inside of the dust collecting device 7 through between the peripheral portion of the filter 20 and the filter holding member 18B.

  Furthermore, in this embodiment, since the vertical ribs 32A and the horizontal ribs 32B as the filter cover are formed integrally with the filter holding member 18B, the number of parts can be reduced and the manufacturing cost can be reduced.

  In this embodiment, the portion of the dust collecting portion 23 that does not face the opening 33 (left side portion) is formed to be narrower than the portion that faces the opening 33 (right side portion). ing. Moreover, the space of the dust collection part 23 is formed so that a cross-sectional area may become narrow gradually toward the part which is not facing the opening 33 (refer FIG. 2). In general, the air swirling in the dust collector 7 tends to flow into a narrower space. By adopting the configuration as described above, the air faces the opening 33 of the exhaust port 19 where air circulation is poor. Since air can be positively guided to the portion that does not face, not only the portion facing the opening 33 but also the entire exhaust port 19 including the portion not facing the opening 33 can be discharged. . Thereby, the collected dust can be guided to a narrow space and gradually accumulated from the space not facing the opening 33, and finally the dust can be captured by the entire filter 20. , Dust collection efficiency is improved.

  The configuration of the dust collector 7 is not limited to the above configuration, and may have the same configuration as that of the dust collector 107 according to the second embodiment described in detail later with reference to FIGS. .

  FIG. 5: is sectional drawing which looked at the cross section when the vacuum cleaner 101 which concerns on 2nd Embodiment of this invention is cut | disconnected by the vertical surface along the front-back direction from the right side. FIG. 6 is a plan view of the electric vacuum cleaner 101 and shows a state where the dust cover 113 is removed. In the following description, the left side in FIG. 5 is the front, the right side is the rear, the upper side in FIG. 6 is the left side, and the lower side is the right side.

  5 and 6, this vacuum cleaner 101 includes a main body 103 including an electric blower 102, and a connection hose (not shown) is connected to a suction port 104 formed at the front end of the main body 103. ) Can be inserted. The connection hose is a long tubular member at least part of which is formed in a bellows shape, and a suction portion is attached to the other end (not shown). When cleaning, the dust blower on the floor surface is sucked together with the air from the suction portion by moving the suction portion along the floor surface while the electric blower 102 provided in the main body 103 is driven. The air sucked from the suction part flows into the main body 103 from the suction port 104 through the connection hose. A plurality of wheels 106 are attached to the lower portion of the main body 103, and the main body 103 can be moved along the floor surface by rolling these wheels 106 along the floor surface. Yes.

  One of the features of the vacuum cleaner 101 is that the air sucked from the suction port 104 is swirled, whereby the dust contained in the air is separated by centrifugal force and captured so as to be captured. (Not shown in FIGS. 5 and 6) and a disposable filter 40 (not shown in FIGS. 5 and 6), such as a commercially available paper pack, can be alternatively mounted. There is in point. According to such a configuration, the user can selectively wear the dust collector 107 or the disposable filter 40 according to his / her preference, so that convenience is improved.

  A blower housing chamber 108 that houses the electric blower 102 is formed on the rear side of the main body 103, and a dust collection chamber 109 that houses the dust collector 107 or the disposable filter 40 is formed on the front side of the main body 103. Has been. When the vacuum cleaner 101 is not used, the power cord 110 for supplying electric power to the vacuum cleaner 101 from the outside is wound around the left side of the blower housing chamber 108 so that the vacuum cleaner 101 can be housed. It has become.

  The upper surface of the dust collection chamber 109 is opened, and the upper surface opening can be covered with the dust cover 113. The dust cover 113 has a rear end attached to the main body 103 so as to be rotatable, and the dust collection chamber 109 can be opened and closed by rotating the dust cover 113 (in FIG. 5, The dust cover 113 is shown open.) A substantially circular opening 114 communicating with the suction port 104 is formed in the front wall 109 </ b> A that partitions the front surface of the dust collection chamber 109. The opening 114 is formed to be slightly upward with respect to the vertical plane, that is, to be inclined forward as it goes upward. A substantially annular packing 117 is attached to the periphery of the opening 114.

  In the upper part of the front end of the dust collection chamber 109 (the front end portion of the upper surface opening), when the disposable filter 40 is accommodated in the dust collection chamber 109, a locking member 41 for fixing the disposable filter 40 is provided in the left-right direction. It is attached so as to be rotatable about an extending rotation shaft (not shown). The locking member 41 includes a base portion 42 extending in the left-right direction, a pair of locking projections 43 protruding rearward from the left and right end portions of the base portion 42, and an operation portion protruding upward from the central portion in the left-right direction of the base portion 42. 44 is formed integrally. The locking member 41 is biased clockwise in FIG. 5 by an elastic member such as a spring, and is held at a position (initial position) as shown in FIG. 5 when the disposable filter 40 is not fixed. ing. On each lower surface of the pair of locking projections 43, a claw portion 43A for hooking the upper end edge of the disposable filter 40 is formed to project.

  FIG. 7 is a cross-sectional view of the vacuum cleaner 101 taken along a vertical plane along the front-rear direction, as viewed from the right side, and shows a state where the disposable filter 40 is attached.

  As shown in FIG. 7, the disposable filter 40 includes a substantially rectangular flat plate-shaped mount 40A and a bag-shaped filter paper filter 40B having an opening fixed to the rear surface of the mount 40A. A substantially circular inlet 45 having a shape corresponding to the opening 114 is formed at the center of the mount 40A, and the rear side of the inlet 45 is covered with a filter paper filter 40B.

  Referring to FIGS. 5 to 7, the left and right sides of the front wall 109 </ b> A of the dust collection chamber 109 are used to guide the left and right edges of the mount 40 </ b> A when the disposable filter 40 is attached to and detached from the dust collection chamber 109. A pair of guide members 46 are formed so as to extend in the vertical direction. Further, at the front end of the bottom surface of the dust collection chamber 109, when the disposable filter 40 is mounted in the dust collection chamber 109, the lower end edge of the mount 40A of the disposable filter 40 is prevented from shifting to the rear side. A pair of stoppers 47 are formed to protrude.

  When the disposable filter 40 is accommodated in the dust collection chamber 109, first, the operation portion 44 is pulled forward, and the locking member 41 is rotated counterclockwise in FIG. The protrusion 43 is retracted from the insertion path of the disposable filter 40 (mounting sheet 40A). In this state, the disposable filter 40 is inserted into the dust collecting chamber 109 from above through the upper surface opening, and the left and right side edges of the mount 40A are slid downward along the pair of guide members 46. In this way, after the bottom edge of the mount 40A is brought into contact with the front side of the pair of stoppers 47 on the bottom surface of the dust collecting chamber 109, the force applied to the locking member 41 is released, and the locking member 41 is moved. By rotating toward the initial position side (clockwise in FIG. 5), the claw portions 43A of the pair of locking projections 43 are locked to the upper edge of the mount 40A. As a result, the mount 40A is pressed against the packing 117 by the forward force received from the locking projection 43, and the peripheral edge of the inlet 45 on the front surface of the mount 40A is pressed against the packing 117, so that the opening 114 and the inlet The gap with 45 is sealed.

  When the vacuum cleaner 101 is operated (the electric blower 102 is driven) with the disposable filter 40 attached, the air sucked from the suction portion flows into the main body 103 via the connection hose and the suction port 104, and the opening 114 To the filter paper filter 40B of the disposable filter 40 through the inlet 45. When the air guided into the filter paper filter 40B passes through the filter paper filter 40B, dust contained in the air is captured.

  Referring to FIGS. 8 and 9, an air inlet 50 into the dust collecting chamber 107 is formed in a substantially circular shape on the front surface of the dust collector 107, and has a cylindrical shape from the inlet 50 toward the front. An inlet pipe 51 is formed to protrude. The front end edge of the inlet pipe 51 is formed so as to be inclined forward as it goes upward corresponding to the inclination of the opening 114.

  The dust collector 107 is made of, for example, resin and has a hollow casing 52 in which air can be swirled, and air exhausted from an exhaust port 53 formed on the rear surface of the casing 52. A filter 54 for capturing dust contained in the air and a filter holding member 55 that surrounds and holds the outer periphery of the filter 54 are provided. The filter 54 is made of a material containing urethane, for example. On both the left and right sides of the lower surface of the filter holding member 55, mounting portions 56 for rotatably mounting the filter holding member 55 to the casing 52 are formed so as to protrude downward. Further, on both the left and right sides of the rear end of the lower surface of the casing 52, fixing portions 57 for fixing the mounting portions 56 of the filter holding member 55 so as to be rotatable are formed so as to protrude downward.

  In this embodiment, a tissue paper can be sandwiched between the casing 52 and the filter holding member 55 (immediately upstream of the filter 54), and the tissue paper sandwiched between the casing 52 and the filter holding member 55 can be sandwiched. Can be pressed by a metal pressing frame 58 that is bent along the outer periphery of the casing 52. The left end of the presser frame 58 is bent toward the right, and the right end of the presser frame 58 is bent toward the left. Both end portions of the presser frame 58 constitute a rotation shaft 63 of the presser frame 58. The presser frame 58 has a left end portion (left rotation shaft 63) fixed to the left attachment portion 56 and a fixed portion. The casing 57 and the filter holding member 55 are attached to the portion 57 so that the right end portion (right turning shaft 63) is rotatably attached to the right attachment portion 56 and the fixing portion 57.

  10 is a cross-sectional view of a portion A shown in FIG.

  As shown in FIG. 10, each mounting portion 56 formed on the filter holding member 55 includes a pair of sandwiching portions 56 </ b> A and 56 </ b> B that face each other in the left-right direction at a predetermined interval. In the pair of sandwiching portions 56A and 56B, substantially cylindrical rotating shafts 59 project along the same axis line from the lower portions of the surfaces facing each other.

  Each fixing portion 57 formed in the casing 52 penetrates the insertion portion 57A inserted between the pair of sandwiching portions 56A and 56B of the corresponding attachment portion 56 and the rotation shaft 63 of the pressing frame 58. Part 57B. A through hole 60 penetrating in the left-right direction is formed in the lower end portion of the insertion portion 57A. By inserting the insertion portion 57A between a pair of sandwiching portions 56A and 56B of the corresponding attachment portion 56, the left side The rotation shaft 59 of the holding portion 56A can be inserted into the through hole 60 from the left side, and the rotation shaft 59 of the right holding portion 56B can be inserted into the through hole 60 from the right side. Thereby, the filter holding member 55 can be rotatably attached to the casing 52.

  A through hole 61 penetrating in the left-right direction is formed in the lower portion of the through portion 57B. Further, of the pair of sandwiching portions 56A, 56B, the sandwiching portion 56A on the penetrating portion 57B side has an insertion hole 62 formed on the penetrating portion 57B side. Therefore, the rotation shaft 63 of the presser frame 58 passes through the corresponding through hole 61, and the end portion thereof is inserted and attached to the corresponding insertion hole 62, so that the rotation shaft 63 is rotatably held. be able to. According to such an attachment structure, the rotation shaft 63 can be attached across the two members of the casing 52 and the filter holding member 55, so that it is difficult to come off from the attachment state and a sturdy structure is provided. it can.

  Further, since the rotation shaft 63 only needs to be inserted / inserted into the corresponding through hole 61 and insertion hole 62, compared to a configuration in which the rotation shaft 63 is attached using a fixture such as an E-ring, Installation can be done with simple work.

  Furthermore, since each end of the rotation shaft 63 is inserted into the insertion hole 62, even if there is a burr at each end, the burr is not exposed to the outside and is safe.

  In FIG. 10, the mounting structure in the vicinity of the left mounting portion 56 and the fixing portion 57 has been described. However, the mounting structure in the vicinity of the right mounting portion 56 and the fixing portion 57 has the same configuration.

  In order to remove dust accumulated in the dust collector 107 (in the casing 52), the dust cover 107 is opened and the dust collector 107 is extracted from the dust chamber 109, and then the rotating shaft 59 of the mounting portion 56 is moved. The inside of the casing 52 can be opened by rotating the filter holding member 55 to the center. In this state, dust in the casing 52 can be easily removed, and the dust attached to the filter 54 can be removed by removing the filter 54 from the filter holding member 55.

  When the dust collector 107 is used with the tissue paper sandwiched between the casing 52 and the filter holding member 55 (immediately upstream of the filter 54) and the peripheral edge of the tissue paper being pressed by the holding frame 58, Since the air in the casing 52 that flows to the exhaust port 53 passes through the tissue paper before passing through the filter 54, most of the dust contained in the air is captured by the tissue paper. In this case, when removing the dust accumulated in the dust collector 107 (in the casing 52), the inside of the casing 52 is opened by rotating the filter holding member 55, and the dust in the casing 52 is easily removed. In addition, the peripheral edge of the tissue paper can be released by rotating the pressing frame 58, and the tissue paper can be removed and discarded. According to such a configuration, since dust hardly adheres to the filter 54, the trouble of removing the dust attached to the filter 54 can be saved, and convenience is improved.

  Referring to FIGS. 8 and 9 again, casing 52 is formed by adhering (for example, welding) a front member 52A constituting the front portion and a rear member 52B constituting the rear portion to each other. Has been. More specifically, on the outer peripheral edge of the rear end of the front member 52A and the outer peripheral edge of the front end of the rear member 52B, bonding ribs for bonding the front member 52A and the rear member 52B to each other over the entire circumference. 64A and 64B are projectingly formed. When these bonding ribs 64A and 64B are brought into contact with each other and a predetermined welding process is performed, the bonding ribs 64A and 64B can be welded together to join the front member 52A and the rear member 52B.

  In this embodiment, a pair of leg members 65 is formed by extending the left and right sides of the lower end of the bonding rib 64A of the front member 52A downward. With such a configuration, when the dust collector 107 is removed from the electric vacuum cleaner 101 and placed on the floor surface when cleaning the dust collector 107, the other pair of leg members 65 and the other of the casing 52 are removed. The portion (the attachment portion 56 and the fixing portion 57) can be erected and held. Accordingly, it is possible to prevent the dust collecting device 107 from falling down and spilling the dust accumulated in the dust collecting device 107, so that the workability when removing the dust accumulated in the dust collecting device 107 can be improved.

  In this embodiment, the lower ends of the pair of leg members 65 are extended to the same height as the lowermost ends of the other parts of the casing 52 (the respective lower ends of the attachment portion 56 and the fixing portion 57). In a state where the dust collector 107 is held upright by using a pair of leg members 65, the inlet 50 of the dust collector 107 is directed substantially in the horizontal direction. According to this configuration, dust collected in the dust collector 107 can be prevented from spilling out from the inlet 50 in a state where the dust collector 107 is erected and held using the pair of leg members 65. The workability at the time of removing dust accumulated in the apparatus 107 can be further improved. However, the configuration is not limited to the configuration in which the inlet 50 of the dust collector 107 faces substantially in the horizontal direction in a state where the dust collector 107 is held upright using the pair of leg members 65, and the inlet 50 is upward (obliquely upward). It is also possible to adopt a configuration that faces the above.

  Furthermore, in this embodiment, the cleaning tool 66 (for example, brush) which can be used at the time of cleaning of the dust collector 107 can be hold | maintained to the rear surface of a pair of leg member 65. FIG. According to such a configuration, since the cleaning tool 66 is not held by the wall surface of the dust collecting chamber 109 but is held by the dust collecting device 107, the filter paper filter 40B of the disposable filter 40 when the disposable filter 40 is attached. Can be prevented from coming into contact with the cleaning tool 66 held on the wall surface of the dust collecting chamber 109 and being damaged.

  In addition, since the pair of leg members 65 are formed by extending a part of the bonding rib 64A, the dust collector 107 can be configured with a simple configuration as compared with a configuration in which the leg members are provided independently. While being able to hold upright, the cleaning tool 66 can be held with a simple configuration.

  The inlet 50 is formed on the front surface of the casing 52 (the front member 52A), and the inlet pipe 51 is projected from the inlet 50 toward the front. In the casing 52, a swirl passage 67 is defined by a partition wall. More specifically, the air that has entered the casing 52 from the inlet 50 is viewed from the front side along the swirl passage 67 around the swirl axis 68 extending in the front-rear direction, as indicated by arrows in FIG. Turn clockwise. The end portion of the swirl passage 67 communicates with a dust collection portion 69 that extends to the upstream side (immediately front side) of the exhaust port 53.

  Dust contained in the air that has flowed into the casing 52 from the inlet 50 in the process of swirling along the swirl flow path 67, due to the action of centrifugal force, on the outer side (with respect to the swirl axis 68). (Radially outward side). A substantially cylindrical filter 70 is disposed in the casing 52 along the turning axis 68. The filter 70 is, for example, a mesh filter formed by joining metal wires in a lattice shape. The rear end of the filter 70 faces the upstream side of the exhaust port 53 in the dust collecting portion 69. With such a configuration, the dust contained in the air swirling along the swirl flow path 67 swirls outward in the swirl flow path 67, and thus is guided to the dust collecting unit 69 without passing through the filter 70. However, a part of the air swirling on the inner side (the swirl axis 68 side) in the swirl flow path 67 (air from which dust has been separated) passes through the filter 70 and passes through the filter 70. It will be led to the upstream side of the exhaust port 53. Accordingly, dust contained in the air flowing into the casing 52 from the inlet 50 can be separated by the centrifugal force and captured by the dust collecting unit 69, and the air from which the dust has been separated is exhausted through the filter 70 through the exhaust port 53. Since it can guide to the side, dust can be captured well.

  A lid 71 that covers the front side of the filter 70 is attached to the front surface of the casing 52 (front member 52A) so as to be opened and closed. By opening the lid 71 and opening the front side of the filter 70, the filter 70 can be pulled out to the front side for cleaning. A rib 72 protruding forward is formed on the side (right side) of the inlet 50 on the front surface of the casing 52 (front member 52A). The rib 72 extends in the vertical direction (the direction in which the dust collector 107 is attached / detached), and the tip thereof extends to the vicinity of the front end of the inlet pipe 51. On the upper part of the casing 52, a gripping portion 73 for gripping when the dust collector 107 is attached and detached extends in the front-rear direction.

  FIG. 11 is a cross-sectional view of the electric vacuum cleaner 101 cut from a vertical plane along the front-rear direction, as viewed from the right side, and shows a state in the middle of mounting the dust collector 107. FIG. 12 is a cross-sectional view of the electric vacuum cleaner 101 as viewed from the right side when the electric vacuum cleaner 101 is cut along a vertical plane along the front-rear direction, and shows a state in which the dust collector 107 is mounted.

  Referring to FIGS. 11 and 12, dust collector 107 is inserted into dust collection chamber 109 from above through the upper surface opening with dust cover 113 opened. That is, the dust collecting device 107 is accommodated in the dust collecting chamber 109 so as to slide vertically downward (along the radial direction of the inlet 50) with respect to the dust collecting chamber 109. The distance between the pair of locking projections 43 of the locking member 41 is set to be larger than the outer diameter of the inlet pipe 51 of the dust collecting device 107, and the dust collecting device 107 is inserted into the dust collecting chamber 109. At this time, as shown by a one-dot chain line in FIG. 11, the inlet pipe 51 passes between the pair of locking projections 43. According to such a configuration, when the disposable filter 40 is accommodated in the dust collection chamber 109, the mount 40A of the disposable filter 40 can be locked using the pair of locking projections 43, and When the dust collector 107 is housed in the dust chamber 109, the inlet pipe 51 of the dust collector 107 interferes with the pair of locking projections 43 for locking the mount 40 </ b> A of the disposable filter 40. Can be prevented. Therefore, the dust collector 107 or the disposable filter 40 can be mounted satisfactorily.

  In a state where the dust collector 107 is mounted in the dust collecting chamber 109, the front end edge of the inlet pipe 51 is pressed against the packing 117 as shown in FIG. The gap is sealed. As described above, the opening 114 is formed to be slightly upward with respect to the vertical plane, that is, to be inclined forward as it goes upward, and the front edge of the inlet pipe 51 is also inclined to the opening 114. Correspondingly, it is formed to incline forward as it goes upward. Therefore, even when the dust collector 107 is inserted into the dust collecting chamber 109 vertically downward, it is possible to prevent the peripheral portion of the opening 114 from interfering with the inlet pipe 51.

  FIG. 13 is a view showing a modification of the packing 117 when the dust collector 107 and the disposable filter 40 are attached. FIG. 13A is an enlarged view of a portion B shown in FIG. 7, and shows a deformation mode of the packing 117 when the disposable filter 40 is mounted, and FIG. 13B is a portion C shown in FIG. 12. FIG. 6 is an enlarged view of the packing 117 when the dust collector 107 is mounted.

  The packing 117 is formed of, for example, an elastic member such as rubber, and has a cylindrical base 117A fitted into the opening 114, a cylindrical portion 117B protruding from the rear surface of the base 117A, and a radially outer side from the rear end of the cylindrical portion 117B. An annular elastic deformation portion 117C projecting toward the side and an annular protrusion 117D protruding rearward from the coupling portion between the cylindrical portion 117B and the annular elastic deformation portion 117C are integrally formed. The annular protrusion 117D is formed in a convexly curved cross section (substantially arcuate cross section).

  When the disposable filter 40 is mounted, as shown in FIG. 13 (a), the annular protrusion 117D bites into the inner periphery of the inlet 45 of the disposable filter 40, and the entire front surface of the mount 40A extends to the entire rear surface of the annular elastic deformation portion 117C. (A peripheral edge portion of the inlet 45) comes into contact, and the annular elastic deformation portion 117C is pressed forward and elastically deformed. On the other hand, the inlet pipe 51 of the dust collector 107 is substantially the same size as the inlet 45 of the disposable filter 40 or larger than the inlet 45 of the disposable filter 40, and when the dust collector 107 is attached, As shown in FIG. 13B, the front end edge of the inlet pipe 51 comes into contact with the rear surface of the annular elastic deforming portion 117C, and the annular elastic deforming portion 117C is pressed forward and is elastically deformed. With such a configuration, regardless of whether the dust collector 107 or the disposable filter 40 is attached, the packing 117 presses the peripheral edge of the inlet 45 or the front end of the inlet pipe 51 with sufficient elastic force, and the peripheral edge of the inlet 45 Since the air can be satisfactorily prevented from leaking from the front part of the inlet and the inlet pipe 51, the dust collection efficiency is improved.

  Further, since the annular protrusion 117D has a convexly curved cross section, the peripheral portion of the inlet 45 and the front end of the inlet pipe 51 are in the process of sliding the dust collector 107 or the disposable filter 40 into the dust collecting chamber 109. Even if the edge interferes with the annular protrusion 117D, it can be moved along the convex curved surface of the annular protrusion 117D. Therefore, the dust collector 107 or the disposable filter 40 can be mounted satisfactorily.

  FIG. 14 is a view showing a modification of the packing 117, FIG. 14 (a) is a view of the packing 217 according to this modification as viewed from the rear, and FIG. 14 (b) is FIG. 14 (a). Sectional drawing seen along the GG line | wire which shows is shown, respectively.

  Referring to FIG. 14, packing 217 according to this modification is formed of an elastic member such as rubber, for example, and similar to packing 117 according to the above-described embodiment, cylindrical base 217 </ b> A fitted into opening 114, and A cylindrical portion 217B that protrudes from the rear surface of the base portion 217A, an annular elastic deformation portion 217C that protrudes radially outward from the rear end of the cylindrical portion 217B, and a coupling portion between the cylindrical portion 217B and the annular elastic deformation portion 217C An annular projection 217D that protrudes rearward from the rear is integrally formed. The annular protrusion 217D is formed in a convexly curved cross section (substantially arcuate cross section).

  The characteristic of the packing 217 according to this modification is that the upper end portion of the annular elastic deformation portion 217C projects further outward (upward) than the other portions to form a guide portion 217E. . The guiding portion 217E is formed in a curved shape that is inclined forward as it goes upward.

  According to such a configuration, in addition to the same effects as the case where the packing 117 according to the above embodiment is adopted, when the dust collector 107 or the disposable filter 40 is mounted, the dust collector 107 inserted from above. The front end edge of the inlet pipe 51 and the mount 40A of the disposable filter 40 can be slidably contacted along the curved surface of the rear surface of the guide portion 217E and can be favorably guided to the annular elastic deformation portion 217C side. Therefore, the dust collector 107 or the disposable filter 40 can be mounted more satisfactorily.

  FIG. 15 is a plan view of the electric vacuum cleaner 101A according to the first modification of the second embodiment, and shows a state where the dust cover 113 is removed.

  In this electric vacuum cleaner 101A, as a fixing part for fixing the mount 40A of the disposable filter 40, instead of using the locking member 41 as in the second embodiment, a part of the pair of guide members 46 is used. It is characterized in that it can be used to lock the mount 40A. Accordingly, the configuration is the same as that of the second embodiment except that the locking member 41 is omitted and the shape of the pair of guide members 46 is changed. Reference numerals are assigned and explanations thereof are omitted.

  Referring to FIG. 15, rear end portions of a pair of guide members 46 (left guide member 46L and right guide member 46R) formed to protrude rearward on the left and right sides of front wall 109A of dust collection chamber 109. Are bent at a substantially right angle toward the opposing guide member side. That is, the rear end portion of the left guide member 46L is formed with a bent portion 48L that is bent toward the right, and the rear end portion of the right guide member 46R is bent toward the left. A bent portion 48R is formed.

  When the disposable filter 40 is accommodated in the dust collection chamber 109, the disposable filter 40 is inserted into the dust collection chamber 109 from above through the upper surface opening, and the left and right side edges of the mount 40A are paired with a pair of guide members 46. Slide downward along the front surfaces of the pair of bent portions 48L and 48R. In this way, after the lower end edge of the mount 40A is brought into contact with the front side of the pair of stoppers 47 on the bottom surface of the dust collection chamber 109, the dust cover 113 is closed. A locking portion (not shown) for locking the upper edge of the mount 40A of the disposable filter 40 is formed on the inner surface of the dust cover 113 (the surface that becomes the dust collection chamber 109 side when closed). When the dust cover 113 is closed, the upper end edge of the mount 40A of the disposable filter 40 is pressed forward by the locking portion. Thus, when the dust cover 113 is closed, the mount 40A is pressed against the packing 117 by the forward force received from the locking portion, and the peripheral edge portion of the inlet 45 on the front surface of the mount 40A is pressed against the packing 117. Thus, the gap between the opening 114 and the inlet 45 is sealed.

  In this modification, the distance between the ends of the pair of bent portions 48L and 48R is set to be larger than the outer diameter of the inlet pipe 51 of the dust collector 107, and the dust collector 107 is placed in the dust chamber 109. When being inserted, the inlet tube 51 passes between the pair of bent portions 48L and 48R. According to such a configuration, when the disposable filter 40 is accommodated in the dust collection chamber 109, the disposable filter 40 can be locked using the pair of bent portions 48L and 48R, and the dust collection chamber 109 can be locked. When the dust device 107 is accommodated in the dust collecting chamber 109, the inlet pipe 51 of the dust collector 107 interferes with the pair of bent portions 48L and 48R for locking the mount 40A of the disposable filter 40. Can be prevented. Therefore, the dust collector 107 or the disposable filter 40 can be mounted satisfactorily.

  FIG. 16 is a cross-sectional view of the electric vacuum cleaner 101B according to the second modification of the second embodiment taken along the vertical plane along the front-rear direction, as viewed from the right side, and is a dust collector 107 or a disposable A state where none of the filters 40 is mounted is shown. FIG. 17 is a cross-sectional view of the dust cover 113 viewed along line DD shown in FIG.

  In this electric vacuum cleaner 101B, the dust collecting device 107 is not accommodated in the dust collecting chamber 109 by the stopper 80 provided in the dust cover 113, and the mount 40A of the disposable filter 40 is fixed to the locking member 41. In the state where the dust cover 113 is not closed, the dust collecting device 107 is accommodated in the dust collecting chamber 109, and the mount 40A of the disposable filter 40 is fixed to the locking member 41. The dust cover 113 is allowed to be closed. Accordingly, since the configuration other than the portion related to the stopper 80 has the same configuration as that of the second embodiment, the same configuration is denoted by the same reference numeral and the description thereof is omitted.

  Referring to FIGS. 16 and 17, a mounting portion 81 for mounting the stopper 80 is formed to project at the central portion in the left-right direction at the front portion of the inner surface of the dust cover 113. A rotating shaft 82 extending in the left-right direction is attached to the lower portion of the attachment portion 81. The stopper 80 has a shape that is long in the front-rear direction, and is rotatably held by the rotary shaft 82 at a position slightly closer to the center of the stopper 80. The rotating shaft 82 is covered with a cylindrical portion of a torsion coil spring 83, one end of the torsion coil spring 83 is locked to the mounting portion 81, and the other end is locked to the stopper 80. Accordingly, the stopper 80 is urged clockwise in FIG. 16 by the urging force of the torsion coil spring 83. When an external force other than the urging force from the torsion coil spring 83 is not acting on the stopper 80, the upper surface of the front end portion of the stopper 80 abuts on the lower surface of the front wall 81A of the mounting portion 81, and the stopper 80 is shown in FIG. It does not rotate further clockwise than the state shown.

  When the dust cover 113 is closed in this state, the operation portion 44 of the locking member 41 is positioned on the locus of the front end portion of the stopper 80. That is, when the dust cover 113 is closed in a state where the dust collecting device 107 is not accommodated in the dust collecting chamber 109 and the mount 40A of the disposable filter 40 is not fixed to the locking member 41, the front end portion of the stopper 80 is closed. Is brought into contact with the upper end of the operation portion 44 of the locking member 41, thereby preventing the dust cover 113 from being closed. A protrusion 80A that protrudes downward is formed at the front end of the lower surface of the stopper 80, and a force is applied in a direction to further close the dust cover 113 with the front end of the stopper 80 being in contact with the upper end of the operation unit 44. Even in such a case, the protrusion 80 </ b> A can prevent the operating portion 44 from getting over the front side of the stopper 80.

  FIG. 18 is a cross-sectional view of the electric vacuum cleaner 101B as viewed from the right side when the electric vacuum cleaner 101B is cut along a vertical plane along the front-rear direction, and shows a state where the disposable filter 40 is mounted.

  As shown in FIG. 18, in the state where the disposable filter 40 is mounted, the upper edge of the mount 40A of the disposable filter 40 is locked by a pair of locking protrusions 43, and the locking member 41 is more than the state shown in FIG. It becomes a position (fixed position) rotated counterclockwise. When the dust cover 113 is closed in this state, the dust cover 113 is allowed to be closed without the front end portion of the stopper 80 coming into contact with the locking member 41 (operation portion 44). .

  The corner portion of the rear end portion of the stopper 80 is chamfered into a smoothly curved shape, and the filter paper filter 40B of the disposable filter 40 accommodated in the dust collecting chamber 109 comes into contact with the rear end portion of the stopper 80, and the filter paper. The filter 40B can be prevented from being broken.

  FIG. 19 is a cross-sectional view of the electric vacuum cleaner 101B as viewed from the right side when the electric vacuum cleaner 101B is cut along a vertical plane along the front-rear direction, and in the middle of closing the dust cover 113 with the dust collector 107 attached. Indicates the state. FIG. 20 is a cross-sectional view of the electric vacuum cleaner 101B as viewed from the right side when the electric vacuum cleaner 101B is cut along a vertical plane along the front-rear direction, and the dust cover 113 is completely closed with the dust collector 107 attached. Shows the state.

  As shown in FIG. 19, when the dust cover 113 is closed in a state where the dust collector 107 is accommodated in the dust chamber 109, the casing 52 (front member) of the dust collector 107 is placed on the locus of the rear end portion of the stopper 80. 52A) is positioned. That is, when the dust cover 113 is closed in a state where the dust collecting device 107 is accommodated in the dust collecting chamber 109, the rear end portion of the stopper 80 comes into contact with the casing 52, and due to the acting force from the casing 52, the stopper 80 is It will rotate counterclockwise in FIG. 19 against the urging force of the torsion coil spring 83.

  When the dust cover 113 is further closed from the state shown in FIG. 19, the rear end portion of the stopper 80 slides along the surface of the casing 52, so that the rear end portion is lifted upward, and the stopper 80 is shown in FIG. 19. When the dust cover 113 is completely closed by rotating counterclockwise, the state shown in FIG. 20 is obtained. As described above, when the dust cover 113 is closed with the dust collector 107 mounted, the stopper 80 rotates by the acting force from the dust collector 107, so that the front end of the stopper 80 is engaged with the locking member 41. The dust cover 113 is allowed to close by being displaced to a position where it does not come into contact with the (operation unit 44).

  According to such a configuration, when either the dust collector 107 or the disposable filter 40 is attached, the dust cover 113 can be closed, but both the dust collector 107 or the disposable filter 40 are attached. If not, the dust cover 113 cannot be closed. Therefore, it is possible to prevent the operation of the electric vacuum cleaner 101B in a state where neither the dust collecting device 107 nor the disposable filter 40 is attached, so that convenience is improved.

  However, the means for applying the urging force to the stopper 80 is not limited to the torsion coil spring 83 but may be another elastic member.

  FIG. 21 is a cross-sectional view of the electric vacuum cleaner 101C according to the third modification of the second embodiment as cut from the horizontal plane when viewed from above, and the dust collector 107 or the disposable filter 40 is attached to the vacuum cleaner 101C. Indicates a state that has not been done. FIG. 22 is a cross-sectional view taken along the line EE shown in FIG. 21 and shows a state where neither the dust collector 107 nor the disposable filter 40 is attached.

  In the vacuum cleaner 101C, the dust collector 107 is not accommodated in the dust collection chamber 109 by the stopper 90 disposed in the dust collection chamber 109, and the mount 40A of the disposable filter 40 is mounted on the locking member 41. In the unfixed state, the dust cover 113 is prevented from being closed, the dust collecting device 107 is accommodated in the dust collecting chamber 109, and the mount 40A of the disposable filter 40 is fixed to the locking member 41. In this state, the dust cover 113 is allowed to be closed. Accordingly, since the configuration other than the portion related to the stopper 90 has the same configuration as that of the second embodiment, the same configuration is denoted by the same reference numeral and the description thereof is omitted.

  Referring to FIGS. 21 and 22, a stopper holding member 91 for holding the stopper 90 is attached to the right side of the front wall 109 </ b> A of the dust collection chamber 109 at the position immediately to the left of the right guide member 46 </ b> R. Yes. The stopper 90 is rotatably held by a rotation shaft 92 that is attached to the stopper holding member 91 so as to extend in the left-right direction. At the front side portion of the inner surface of the dust cover 113, a locking projection 93 that can be locked to the stopper 90 is formed to protrude. The stopper 90 has an elongated shape in the vertical direction, and a lower portion thereof is rotatably held by a rotation shaft 92. A columnar projection 90A is formed on the front surface of the lower end portion of the stopper 90, and the compression coil spring 94 whose front end surface is in contact with the rear surface of the stopper holding member 91 is covered with the columnar projection 90A. The stopper 90 is urged counterclockwise in FIG. 22 by the urging force of the coil spring 94. In a state where an external force other than the urging force from the compression coil spring 94 is not acting on the stopper 90, the tip of the rib 90B protruding from the upper front portion of the stopper 90 comes into contact with the rear surface of the stopper holding member 91, and the stopper 90 is in FIG. Is prevented from rotating further counterclockwise than the state shown in FIG.

  When the dust cover 113 is closed in this state, the upper end portion of the stopper 90 is positioned on the locus of the lower end portion of the locking projection 93. That is, when the dust cover 113 is closed in a state where the dust collecting device 107 is not accommodated in the dust collecting chamber 109 and the mount 40A of the disposable filter 40 is not fixed to the locking member 41, the locking protrusion 93 is obtained. Since the lower end surface of the abutment contacts the upper end surface of the stopper 90, the dust cover 113 is prevented from being closed. Projections 95 projecting upward are formed at the front end and the rear end of the upper end surface of the stopper 90, respectively, and the lower end surface of the locking projection 93 is in contact with the upper end surface of the stopper 90. In contrast, even when a force is further applied in the closing direction, the protrusion 95 can prevent the locking protrusion 93 from getting over the front side or the rear side of the stopper 90.

  FIG. 23 is a cross-sectional view taken along the line EE shown in FIG. 21 and shows a state where the disposable filter 40 is attached.

  The stopper 90 is positioned in the insertion path of the mount 40A of the disposable filter 40. When the disposable filter 40 is mounted, the front surface of the mount 40A is stopped in the process of sliding the mount 40A downward along the guide member 46. 90 is in sliding contact with the rear surface. Thereby, in the process in which the disposable filter 40 is mounted, the stopper 90 resists the biasing force of the compression coil spring 94 from the position (initial position) shown in FIG. 22 by the acting force from the disposable filter 40 (mount 40A). And rotate clockwise. And as shown in FIG. 23, in the state which mounted | worn with the disposable filter 40, the whole rear surface of the stopper 90 contact | abuts to the front surface of the mount 40A of the disposable filter 40. FIG. When the dust cover 113 is closed in this state, the dust cover 113 is allowed to be closed without the lower end surface of the locking projection 93 contacting the upper end surface of the stopper 90.

  FIG. 24 is a cross-sectional view of the electric vacuum cleaner 101 </ b> C cut from a horizontal plane as seen from above, and shows a state in which the dust collecting device 107 is attached. FIG. 25 is a cross-sectional view taken along line FF shown in FIG. 24 and shows a state in which the dust collector 107 is attached.

  As described with reference to FIGS. 8 to 10, the rib 72 extending in the vertical direction (the direction in which the dust collector 107 is attached or detached) is formed on the side (right side) of the inlet 50 on the front surface of the dust collector 107 (casing 52). However, it protrudes toward the front. The stopper 90 is located in the insertion path of the rib 72 of the dust collector 107. When the dust collector 107 is mounted, the stopper 90 is slid downward in the process of sliding the dust collector 107 downward. ) Is in sliding contact with the rear surface of the stopper 90. Thus, in the process of attaching the dust collector 107, the stopper 90 is biased by the compression coil spring 94 from the position (initial position) shown in FIG. 22 by the acting force from the dust collector 107 (rib 72). It will rotate clockwise against this. As shown in FIG. 25, in the state where the dust collector 107 is mounted, the entire front end surface of the rib 72 of the dust collector 107 abuts on the rear surface of the stopper 90. When the dust cover 113 is closed in this state, the dust cover 113 is allowed to be closed without the lower end surface of the locking projection 93 contacting the upper end surface of the stopper 90.

  According to such a configuration, when either the dust collector 107 or the disposable filter 40 is attached, the dust cover 113 can be closed, but both the dust collector 107 or the disposable filter 40 are attached. If not, the dust cover 113 cannot be closed. Therefore, it is possible to prevent the operation of the electric vacuum cleaner 101C from being started in a state where neither the dust collector 107 nor the disposable filter 40 is attached, so that convenience is improved.

  However, the means for applying the urging force to the stopper 90 is not limited to the compression coil spring 94 but may be another elastic member.

  The present invention is not limited to the contents of the above embodiments, and various modifications can be made within the scope of the claims.
