  In FIG. 1, the vacuum cleaner body 2 of the electric vacuum cleaner 1 separates dust from air containing dust (dust-containing air), and discharges the air (clean air) from which the dust has been removed (for example, returned to the room). Is for. The cleaner body 2 is provided with a dust collecting portion 2a that captures and collects dust (dust) in the dust-containing air that has flowed into the cleaner body 2. The vacuum cleaner body 2 includes an electric blower 2b. The electric blower 2b is for creating an air flow for sucking dust-containing air into the dust collecting part 2a of the cleaner body 2.

  One end of the hose 3 is connected to the front end of the cleaner body 2. This hose 3 consists of a cylindrical member provided with flexibility by the bellows. One end of the connection pipe 4 is connected to the other end of the hose 3. The connection pipe 4 is formed of a hollow cylindrical member that is bent halfway. The connection pipe 4 is provided with a handle portion 4a. The handle 4a is for a user of the vacuum cleaner to operate. The handle portion 4a is provided with an operation switch for controlling the operation of the electric vacuum cleaner 1.

  One end of the suction pipe 5 is connected to the other end of the connection pipe 4. The suction pipe 5 is made of a straight member having a hollow cylindrical shape. A cleaning tool 6 is connected to the other end (exhaust side) of the suction pipe 5. This cleaning tool 6 is for sucking together dust (dust) on the floor surface together with air from an opening formed downward.

  FIG. 2 shows details of the cleaning tool 6. The cleaning tool 6 includes a frame body 7, a gap closing portion 8, and a connecting member 9. The frame 7 is composed of a member that has a substantially semi-cylindrical shape. A lower opening 7 a is formed on the lower surface side of the frame body 7. A front opening 7 b is provided on the front side of the frame body 7, that is, on the side opposite to the side connected to the connection pipe 4. An opening having the same shape as the front opening 7 b is also provided on the rear side of the frame body 7, that is, on the side connected to the connection pipe 4.

  The gap closing portion 8 is also composed of a member having a substantially semi-cylindrical shape like the frame body 7. However, the radius dimension of the substantially semicylindrical shape of the gap closing portion 8 is formed to be slightly larger than that of the frame body 7. The gap closing portion 8 is disposed on the outer peripheral side on the rear side of the frame body 7 (the side connected to the connection pipe 4). The frame body 7 and the gap closing portion 8 are provided to be slidable in the front-rear direction.

  One end of the connecting member 9 is attached to the rear side of the gap closing portion 8. The other end of the connecting member 9 is detachably attached to the tip of the suction pipe 5. A pair of rotating shafts 9 a is provided at the one end portion attached to the gap closing portion 8 of the connecting member 9. These rotation shafts 9a are provided on the left and right sides of the one end side of the connecting member 9 so as to protrude outward.

  Correspondingly, a recess is provided on the lower inner surface on the rear side attached to the connecting member 9 of the gap closing portion 8. Then, by engaging the distal end portion of the rotation shaft 9a of the connecting member 9 in the recess of the gap closing portion 8, the gap closing portion 8 and the connecting member 9 are rotated about an axis along the left-right direction. Mounted freely.

  In this manner, the connection angle between the frame body 7 and the suction pipe 5 can be adjusted, so that the user holds the handle portion 4a and applies the lower opening 7a of the cleaning tool 6 to the surface to be cleaned for cleaning. When performing, the lower opening 7a can follow the surface to be cleaned.

  A pair of support plates 9 b are provided at the one end of the connecting member 9. These support plates 9b are formed of flat plate-like members provided so as to protrude outward on the upper side of the rotation shaft 9a on the left and right sides of the one end side of the connecting member 9, respectively.

  A winding spring 10 is attached around the rotation shaft 9a. The winding spring 10 rotates the gap closing portion 8 with respect to the connecting member 9 in a direction in which the gap closing portion 8 or the rear end of the frame body 7 is brought into contact with the support plate 9b of the connecting member 9. Is energized.

  The frame body 7 and the gap closing portion 8 are moved from the use position shown in FIG. 2 to the storage position shown in FIG. 4 through the state shown in FIG. Rotate. Conversely, the frame body 7 and the gap closing portion 8 may be rotated with respect to the connecting member 9 from the storage position shown in FIG. 4 to the use position shown in FIG. 2 via the state shown in FIG. Is possible.

  In the use position, the rear end of the frame body 7 or the gap closing portion 8 is in contact with the support plate 9b. The support plate 9b rotates the frame body 7 and the gap closing portion 8 so that the frame body 7 and the gap closing portion 8 are disposed at the use position when the frame body 7 and the gap closing portion 8 are rotated. It can also be said to regulate the range.

  Further, the frame body 7 and the gap closing portion 8 in the storage position are arranged at positions along the outer periphery of the connecting member 9 and the suction pipe 5. In this state, the extension pipe 11 or another cleaning tool (not shown) can be further connected to the tip of the suction pipe 5 (FIG. 5).

  In this way, the frame body 7 is disposed such that the space from the space in the frame body 7 to the space in the suction pipe 5 is continuous, and the frame body 7 is disposed outside the suction pipe 5. It is provided so as to be movable between the storage positions. For this reason, when the cleaning tool 6 is not used, the extension pipe 11 or another cleaning tool is connected to the tip of the suction pipe 5 while the cleaning tool 6 is attached to the suction pipe 5. Can be very convenient. In the use position, the tip of the suction pipe 5 is arranged below the rear of the frame body 7.

  A concave groove-like spring accommodating portion 7c is formed in the substantially central portion of the outer periphery of the frame body 7 in the front-rear direction. A push spring 12 is housed in the spring housing portion 7c. With reference to FIGS. 6 and 7, the attached state of the pressing spring 12 and the operation of the frame body 7 and the gap closing portion 8 by the pressing spring 12 will be described. One end on the rear side of the pressing spring 12 is locked to a frame body side spring locking portion 7 d provided at the rear end portion of the spring housing portion 7 c of the frame body 7. The other end on the front side of the pressing spring 12 is locked to a gap closing portion side spring locking portion 8 a provided near the front end of the inner peripheral surface of the gap closing portion 8.

  Accordingly, the push spring 12 biases the frame body 7 toward the rear side with respect to the gap closing portion 8. As described above, the support plate 9b of the connecting member 9 is disposed on the rear side of the gap closing portion 8. In other words, it can be said that the pressing spring 12 biases the frame body 7 in the direction in which the frame body 7 is pressed against the support plate 9 b of the connecting member 9.

  When the front end side (left side as viewed in the drawing) of the frame body 7 is lowered downward from the state in which the frame body 7 is disposed substantially horizontally (FIG. 6), the frame body 7 becomes a gap closing portion by the action of the pressing spring 12. It is pushed backward (right side as viewed in the drawing) from 8 (FIG. 7). For this reason, as shown in FIG. 8, even if the orientation of the frame body 7 with respect to the connecting member 9 changes, the state in which the rear end portion of the frame body 7 abuts against the support plate 9b by the pressing spring 12 is maintained. Further, it is possible to prevent a large gap from being formed between the rear end portion of the frame body 7 and the connecting member 9.

  In this way, by providing the gap closing portion 8 at the connection portion between the frame body 7 and the suction pipe 5 so as to close the gap generated according to the change in the connection angle between the frame body 7 and the suction pipe 5. The airflow leakage at the connecting portion between the frame body 7 and the suction pipe 5 is suppressed, and the reduction in the suction force of the cleaner body 2 and the reduction in the cleaning ability of the cleaning tool 6 due to the weakening of the vibration of each wiping sheet are suppressed. be able to.

  As described above, the cleaning tool 6 is detachable from the suction pipe 5. FIG. 9 shows a single cleaning tool 6 removed from the suction pipe 5. As shown in FIG. 9, the left and right sides of the connecting member 9 on the rear side, that is, the side connected to the suction pipe 5, are cut out in a substantially U shape to form a cutout portion 9c.

  The inner diameter dimension of the connecting member 9 on the side connected to the suction pipe 5 is adjusted to be slightly smaller than the outer diameter dimension of the suction pipe 5. The connecting member 9 is produced by integrally molding a resin such as plastic and has a certain degree of elasticity. The connecting member 9 is formed of a cylindrical member with an upper portion cut off. Further, by forming the notch portions 9c on both sides, the connecting member 9 is adjusted so that the side connected to the suction pipe 5 is appropriately elastically deformed. The The connecting member 9 can be appropriately attached to and detached from the suction pipe 5 by utilizing the restoring force at the time of elastic deformation.

  A bristle brush unit 5 a is provided near the tip of the suction pipe 5. By rotating the bristle brush unit 5a to the position shown in FIG. 10 with the cleaning tool 6 removed from the suction pipe 5, the user of the electric vacuum cleaner 1 uses the brush of the bristle brush unit 5a for cleaning and electricity. Suction by the vacuum cleaner 1 can be performed. When the cleaning tool 6 is attached to the suction pipe 5, the bristle brush unit 5a is rotationally moved to a storage position as shown in FIGS. 2 and 3, for example.

  Returning to FIG. 2 again, at the portion facing the front opening 7b in the frame body 7, three sheet support members, that is, a center sheet support member 13a, a left sheet support member 13b, and a right sheet support member 13c are attached. . These sheet support members are formed, for example, by bending a thin rod-shaped metal member into a substantially L shape. These sheet support members have one side of the substantially L shape attached to the inner peripheral surface of the frame body 7 and the other side of the substantially L shape is disposed along the opening surface of the front opening 7b. At this time, the other side of the substantially L-shape is arranged so as to be substantially perpendicular to the inner peripheral surface of the frame body 7.

  A configuration for attaching these sheet support members to the frame body 7 will be described with reference to FIGS. 11 and 12. These sheet support members are provided on the claw-shaped support member fixing portions provided on the inner peripheral surface on the front side of the frame body 7 corresponding to the respective sheet support members, and the substantially L-shaped of each sheet support member. The frame 7 is attached by engaging the one side.

  Specifically, the center sheet support member 13a is engaged and attached to a center support member fixing portion 14a provided at a substantially central portion near the front on the inner peripheral surface of the frame body 7. The left seat support member 13b is engaged with and attached to a left support member fixing portion 14b provided near the front on the inner peripheral surface of the frame body 7 and on one side in the vicinity of the lower opening 7a. Further, the right seat support member 13c is engaged with and attached to a right support member fixing portion 14c provided near the front side on the inner peripheral surface of the frame body 7 and on the other side near the lower opening 7a.

  The substantially L-shaped one side of these sheet support members can be rotated with respect to the corresponding support member fixing portion about the longitudinal direction of the one side. Engaged. Therefore, each sheet support member is used in a position in which the other side of the substantially L-shape is erected substantially vertically with respect to the inner peripheral surface of the frame body 7 (for example, FIGS. 2 and 3). And the storage position (for example, FIG. 11 and FIG. 12) in which the other side of the substantially L-shape is laid down along the inner peripheral surface of the frame body 7 It is possible.

  A wiping sheet is attached to each other side of the substantially L-shape of each sheet support member. Specifically, a central wiping sheet 15a is attached to the other side of the substantially L-shaped center sheet support member 13a, and the other side of the substantially L-shaped left sheet support member 13b is The left wiping sheet 15b is attached, and the right wiping sheet 15c is attached to the substantially L-shaped other side of the right sheet supporting member 13c.

  These wiping sheets are made of a thin plate-like sheet body having a substantially rectangular shape or a substantially strip shape. These wiping sheets are made of a material having sufficient flexibility to be able to vibrate due to the action of the air flow when there is an air flow of a certain speed or more around the wiping sheet. As such a material, for example, various cloths such as paper, woven fabric or knitted fabric, non-woven fabric, plastic sheet, vinyl sheet and the like can be used. Especially, a nonwoven fabric is suitable.

  By fixing the short side of the corresponding wiping sheet to the other side of the substantially L shape of each sheet supporting member, each wiping sheet is attached to the corresponding sheet supporting member. The length of the short side of these wiping sheets is substantially the same as the length of the said other side of the said substantially L shape of each sheet | seat support member which supports these wiping sheets.

  On the other hand, the length of the long side of the wiping sheet is different between the central sheet supporting member 13a, the left wiping sheet 15b, and the right wiping sheet 15c. Specifically, the length of the long side of the central wiping sheet 15 a is slightly shorter than the length of the frame body 7 in the front-rear direction. On the other hand, the length of the long side of the left wiping sheet 15b and the right wiping sheet 15c is shorter than the central wiping sheet 15a and is about half of the central wiping sheet 15a.

  The substantially L-shaped other side of the sheet supporting member to which each wiping sheet is attached is disposed substantially perpendicular to the inner peripheral surface of the frame 7 at the use position as described above. For this reason, the central wiping sheet 15a attached to the central sheet support member 13a is disposed such that one end edge of the long side faces the opening surface of the lower opening 7a. Further, the left wiping sheet 15b and the right wiping sheet 15c attached to the left sheet supporting member 13b and the right sheet supporting member 13c, respectively, have a substantially rectangular shape opposed to the opening surface of the lower opening 7a. Be placed.

  In other words, the center sheet support member 13a is provided so as to protrude downward from the center of the front upper portion of the frame body 7, that is, in a direction perpendicular to the opening surface of the lower opening 7a. Further, the left seat support member 13b and the right seat support member 13c are provided so as to protrude from the front left and right sides of the frame body 7 in a direction parallel to the opening surface of the lower opening 7a.

  When the frame body 7 and the gap closing portion 8 are in the use positions as shown in FIG. 2, the center sheet support member 13a, the left sheet support member 13b, and the right sheet support member 13c are also used positions in the frame body 7. Can be pulled out and placed.

  On the other hand, when the frame body 7 and the gap closing portion 8 are in the storage positions as shown in FIGS. 4 and 5, the sheet support members and the suction pipe 5 are not left in the use positions as they are. Will interfere. Therefore, when the frame body 7 and the gap blockage portion 8 are set to the storage position, the sheet support members are set to the storage position before the frame body 7 and the gap blockage portion 8 along the inner peripheral surface of the frame body 7, and then the frame body 7 and the gap blockage portion are set. By setting 8 to the storage position, interference between the sheet support member and the suction pipe 5 can be avoided.

  As shown in FIGS. 11 and 12, a pair of guide portions 7e are formed on the left and right side edges of the lower opening 7a of the frame body 7 in the front-rear direction. These guide portions 7 e protrude outward from the outer peripheral surface of the frame body 7. These guide portions 7e are slidably engaged with the gap closing portion 8. These guide portions 7e are for guiding the sliding direction when the frame body 7 slides in the front-rear direction with respect to the gap closing portion 8.

  In the cleaner body 2 including the cleaning tool 6 configured as described above, the suction pipe 5 extends from the lower opening 7a and the front opening 7b of the cleaning tool 6 to the dust collection part 2a of the cleaner body 2. It is formed continuously through the inside of the connection pipe 4 and the hose 3. That is, the cleaning tool 6, the suction pipe 5, the connection pipe 4, and the hose 3 constitute a part of a suction path for allowing dust-containing air to flow into the dust collection part 2 a of the cleaner body 2.

  When the user starts the suction operation of the electric blower 2b by operating the operation switch of the handle portion 4a or the like, the airflow sucked into the suction pipe 5 from the lower opening portion 7a and the front opening portion 7b toward the rear in the frame body 7 Will occur.

  In this state, when the lower opening 7a is applied to the floor surface to be cleaned, the lower opening 7a and the surface to be cleaned are opposed to each other, and the gap through which air can be sucked from the lower opening 7a is reduced. On the other hand, the opening side of the front opening 7b remains wide open. Therefore, when the lower opening 7a of the cleaning tool 6 is applied to the surface to be cleaned, the airflow that mainly flows into the frame 7 from the front opening 7b and flows from the front toward the rear in the frame 7 is dominant. .

  The central wiping sheet 15a, the left wiping sheet 15b, and the right wiping sheet 15c are arranged in the airflow generated in the frame body 7 in this way. Then, each wiping sheet flutters and vibrates due to the airflow around each wiping sheet.

  At this time, since the central wiping sheet 15a is disposed so that one end edge of the long side faces the opening surface of the lower opening 7a as described above, the one end edge of the central wiping sheet 15a is cleaned. Make a round trip to the left and right of the surface. And the to-be-cleaned surface is wiped by the said one edge of the center wiping sheet | seat 15a, or it is swept away, and the dust on a to-be-cleaned surface can be removed efficiently, and it can attract | suck to the cleaner body 2.

  Moreover, since the left-side wiping sheet 15b and the right-side wiping sheet 15c are disposed so that one surface thereof faces the opening surface of the lower opening 7a, the one surface of the left-side wiping sheet 15b and the right-side wiping sheet 15c is cleaned. Waves up and down so that it can be struck on the surface. And the said one surface of the left-side wiping sheet 15b and the right-side wiping sheet | seat 15c removes the dust on a to-be-cleaned surface efficiently according to the principle similar to what is called "hataki". The dust removed from the surface to be cleaned is sucked into the cleaner body 2.

  FIG. 13 shows a cleaning area where each wiping sheet can remove dust on the surface to be cleaned. One end of the central wiping sheet 15a is fixed on the upstream side of the airflow formed in the frame body 7 by the central sheet support member 13a. The central wiping sheet 15a vibrates so as to wave from side to side with the fixed point as the central axis. Therefore, the central sheet cleaning region 16a where the dust on the surface to be cleaned can be removed by the central wiping sheet 15a is the narrowest at the position where the upstream central wiping sheet 15a is fixed, and gradually becomes wider toward the downstream. It becomes a shape.

  On the other hand, for the left-side sheet cleaning region 16b by the left-side wiping sheet 15b and the right-side sheet cleaning region 16c by the right-side wiping sheet 15c, these wiping sheets have a substantially rectangular surface facing the surface to be cleaned. The width is not significantly different between the upstream side and the downstream side.

  As can be seen from FIG. 13, in the central wiping sheet 15a, the left and right sides near the central sheet supporting member 13a to which the central wiping sheet 15a is fixed cannot be cleaned. Therefore, by arranging the left wiping sheet 15b and the right wiping sheet 15c on the left and right sides of the central sheet support member 13a, it is possible to clean even a range that cannot be covered only by the central wiping sheet 15a.

  In this way, the surface of the wiping sheet provided in the center is substantially perpendicular to the surface to be cleaned, the left and right wiping sheets are shortened from the center, and the surface of the wiping sheet is covered. By arranging it so that it is almost parallel to the cleaning surface, the central wiping sheet cleans the downstream side of the airflow more widely, and the left and right sides of the upstream side where cleaning leakage occurs only with the central wiping sheet Cleaning can be performed with the left and right wiping sheets, and almost the entire area of the lower opening 7 a of the cleaning tool 6 can be set as the cleaning range.

  As shown in FIGS. 2 and 3, bristle brush portions 7 f are provided downward on the left and right side edges of the lower opening 7 a near the front of the frame body 7. Therefore, when cleaning is performed by moving the cleaning tool 6 back and forth and right and left with respect to the surface to be cleaned, in addition to the cleaning effect of each wiping sheet, dust on the surface to be cleaned is also supplementarily removed by the bristle brush portion 7f. Effect can be obtained. Moreover, it can replace with this bristle brush part 7f, and the same effect can be acquired even if it uses a nonwoven fabric etc., for example.

  Furthermore, by making each wiping sheet detachable with respect to each sheet support member, even when the wiping sheet becomes dirty or deteriorates, and the cleaning ability of the cleaning tool 6 is reduced, the wiping sheet can be easily replaced with a new one. It can be exchanged for a convenience. Further, the same effect can be obtained by making each sheet support member detachable from the frame body 7.

  In the cleaning tool configured as described above, one end of each wiping sheet is fixed by each sheet support member so that at least a part thereof can contact the surface to be cleaned. At this time, one end of the wiping sheet fixed by the sheet support member is disposed on the upstream side of the airflow generated in the frame of the cleaning tool when the electric vacuum cleaner is in operation. And by the effect | action of the airflow which generate | occur | produces in this way, each wipe sheet vibrates with each end fixed, and removes the dust on a to-be-cleaned surface.

  In addition, a front opening is formed on the front surface, a lower opening is formed on the lower surface, and includes a frame that serves as an air passage for the airflow, and each wiping sheet is disposed so as to face the lower opening in the frame, One end is fixed to each sheet support member provided on the front opening side of the frame.

  For this reason, it is a small and simple configuration, and by driving the operation of the wiping sheet that is the cleaning body by the air flow generated by the electric blower of the vacuum cleaner, the cleaning body for removing dust on the surface to be cleaned A special power source for driving the operation is unnecessary, and dust on the surface to be cleaned can be efficiently removed and only the surface to be cleaned can be obtained. Furthermore, lint and hair are not easily entangled, and these do not adversely affect the cleaning effect.

  In addition, each wiping sheet contacts and rubs violently with a to-be-cleaned surface and a frame. Therefore, each wiping sheet and / or frame may be provided with an antistatic function. For example, each wiping sheet and frame is made of a material to which an antistatic agent such as carbon is added. Carbon may be fibrous. An antistatic agent made of an organic compound such as an anionic, cationic or nonionic surfactant may be added to each wiping sheet. Or you may comprise each wiping sheet with the material which apply | coated the antistatic agent which consists of an organic compound as mentioned above. By providing each wiping sheet and / or frame body with an antistatic agent inside or on the surface, static electricity generated by the contact between each wiping sheet and the surface to be cleaned or each wiping sheet and the frame body can be reduced. Thereby, the dust adhering to a frame can be decreased. In addition, it is possible to enhance the effect of removing dust charged and adhering to the surface to be cleaned.

  The central wiping sheet 15a may be configured by stacking a plurality of sheets.
