Description

Electric vacuum cleaner

Technical Field

Embodiments of the present invention relate to an electric vacuum cleaner for holding a dust bag in a dust chamber.

Background

Conventionally, in an electric vacuum cleaner in which a dust bag is attached to a dust collecting chamber and used, there is a vacuum cleaner in which a holding portion for holding a pocket frame of the dust bag and a holding unit for locking the dust bag held by the holding portion are provided in the dust collecting chamber. The holding unit is forced towards the inner side of the dust collection chamber to press the bag opening frame of the dust collection bag. Therefore, the holding unit is inclined toward the inner side of the dust collecting chamber in a state that the dust collecting bag is not mounted in the dust collecting chamber, and the cover body is not closed by being abutted with the cover body for opening and closing the dust collecting chamber, thereby playing a role as a safety device for avoiding that the electric dust collector is used by mistake when the dust collecting bag is not mounted.

Since such a holding unit largely occupies the mounting path of the dust bag in a state where the dust bag is not mounted, it is necessary to raise the holding unit against a biasing force so as to retract when the dust bag is mounted, and to insert the bag opening frame into the gap between the holding unit and the holding portion while maintaining the retracted state, and the mounting work is troublesome.

Detailed Description

Hereinafter, an embodiment will be described with reference to the drawings.

In fig. 8, numeral 1 denotes an electric vacuum cleaner. In the present embodiment, the user moves the electric vacuum cleaner 1 while walking on the floor surface, collects dust on the floor surface, and cleans the floor surface. In the present embodiment, a horizontal type electric vacuum cleaner is described as an example of the electric vacuum cleaner 1, but a vertical type, a stick type, a hand-held type electric vacuum cleaner, or the like may be used, or an autonomous traveling type sweeping robot may be used. In the present embodiment, the front-back direction, the left-right direction, and the up-down direction are described with reference to a state in which the horizontal type electric vacuum cleaner 1 is placed on a plane such as a floor surface.

The electric vacuum cleaner 1 includes a cleaner main body 2. In the present embodiment, the air duct body 3 is detachably connected to the cleaner main body 2. The air passage body 3 forms a suction air passage. In the present embodiment, the air passage body 3 includes a flexible tube body 4, an extension tube 5, and a suction port body 6. Further, air duct body 3 includes an operation portion 7 for a user to perform a gripping operation. A setting unit 8 is disposed in the operation unit 7, and the setting unit 8 is used to set the start and stop of the electric vacuum cleaner 1. In addition, the air duct body 3 may be configured to correspond to each of the modes when the electric vacuum cleaner 1 is of a vertical type, a pole type, or a hand-held type, and is not required when the electric vacuum cleaner 1 is a sweeping robot.

A suction port 9 is formed in the cleaner body 2. The suction port 9 is located at the front end of the cleaner body 2, but is not limited to this position. In the present embodiment, the air duct body 3 is connected to the suction port 9. Further, a suction port seal 10 (see fig. 6) is attached to the suction port 9. The suction port seal 10 is formed of an elastic member or the like, and is attached to the downstream end side of the suction port 9.

As shown in fig. 6 and 7, the cleaner body 2 includes a main body 11. The main body 11 has a dust collecting chamber 12 formed therein. A dust collection chamber 12 is formed at the front of the cleaner body 2. Dust collection chamber 12 communicates with suction port 9, and a downstream end portion of suction port seal 10 attached to suction port 9 protrudes into dust collection chamber 12. The dust collecting chamber 12 of the present embodiment is open at the upper side. The dust collecting chamber 12 may be opened to the left or right, and is not particularly limited. A sealing member 13 for sealing the dust collecting chamber 12 is attached to an opening edge of the dust collecting chamber 12. The sealing member 13 is formed of, for example, an elastically deformable member. The sealing member 13 is continuously disposed along the opening edge of the dust collecting chamber 12. The dust collecting chamber 12 is openable and closable by a lid 14. The lid 14 is rotatably supported by the main body 11, and the closing portion 15 is pressed against the sealing member 13 in a state where the dust collecting chamber 12 is closed, thereby hermetically closing the dust collecting chamber 12. The lid 14 is locked to the body 11 by the locking means 16 in a state where the dust collecting chamber 12 is closed. The locking unit 16 may be formed on the cover 14 or the main body 11. As shown in fig. 6, the dust collecting chamber 12 communicates with the intake side of an electric blower 17 serving as a suction source disposed in the main body 11. The electric blower 17 is operated by power supplied from a power supply unit such as a lead reel device or a secondary battery disposed in the main body 11, and is controlled by the control unit 19. The exhaust side of the electric blower 17 communicates with an exhaust port 20 provided in the cleaner body 2.

Further, as shown in fig. 1, for example, a dust bag 22 is attached to the dust chamber 12. The dust bag 22 is used for filtering and trapping dust from dust-containing air. As the dust bag 22, a paper bag, a cloth bag, or the like is used. The dust bag 22 of the present embodiment is configured to be attached to the dust chamber 12 from the upper side, but is not limited to attachment from this direction, and the dust bag 22 may be configured to be attached from the left side or the right side. The dust bag 22 of the present embodiment includes a pocket frame 23. The pocket frame 23 is formed of hard paper or thick paper. Further, pocket frame 23 is formed in a rectangular shape, and has opening 24 communicating with suction port 9 in a state of being attached to dust collection chamber 12.

The dust bag 22 is provided with a filter portion 25. The filter material portion 25 allows dust-containing air to pass through the filter material portion, thereby filtering dust. The filter section 25 is formed in a bag shape of a single-layer or multi-layer filter medium or the like, integrally connected to the bag opening frame 23, and the inside thereof communicates with the opening 24. In fig. 6, the dust bag 22 is shown in a state before use in which the filter material portion 25 is folded, but the filter material portion 25 expands in the dust collecting chamber 12 by introducing dust-containing air into the inside. The dust bag 22 is held by a dust bag holder 26 provided in the dust chamber 12.

The dust bag holding portions 26 are located on both left and right sides of the suction port 9. The dust bag holder 26 is disposed on the suction side of the dust chamber 12. The dust bag holder 26 of the present embodiment is disposed at the front end portion in the dust collecting chamber 12. The position of the dust bag holder 26 is not limited to this position. The dust bag holding portion 26 of the present embodiment is disposed separately on both sides of the inlet seal 10. The dust bag holding portion 26 includes a side portion regulating portion 27 (see fig. 1 to 3) that regulates the position of the side portion of the bag opening frame 23 of the dust bag 22. The side restricting portion 27 is formed to extend toward the side into which the dust bag 22 is inserted, that is, toward the opening of the dust chamber 12. The side restricting portions 27 of the present embodiment protrude upward from the bottom of the dust collecting chamber 12, but are not limited to this direction. The dust bag holder 26 includes a position regulating portion 28 for regulating the position of the bag opening frame 23 of the dust bag 22 opposite to the suction port 9. The position regulating portion 28 connects the opening 24 of the bag opening frame 23 of the dust bag 22 to the suction port 9 in an airtight manner by bringing the periphery of the opening 24 into close contact with the suction port seal 10. The position restricting portion 28 is located inside, i.e., on the rear side of the dust collecting chamber 12, separately from the suction port 9 and/or the suction port seal 10. The position of the position restricting portion 28 is not limited to this position. In addition, the position restricting portion 28 is formed continuously with the side restricting portion 27. The position restricting portion 28 is formed to extend toward the side into which the dust bag 22 is inserted, i.e., the opening direction of the dust collecting chamber 12. The position regulating portion 28 is formed with an introduction portion 30, and the introduction portion 30 extends toward the opening of the dust collecting chamber 12, which is the side into which the dust bag 22 is inserted, and is inclined in a direction away from the suction port 9. The introduction portion 30 of the present embodiment introduces the pocket opening frame 23 of the dust bag 22 between the position regulating portion 28 and the suction port 9 or the suction port seal 10. The introduction portion 30 is located at the upper end of the position regulating portion 28 and is formed to be inclined upward and rearward. The position and the inclination direction of the introduction portion 30 are not limited to these positions and directions.

The dust bag holder 26 is provided with a rotatable member 32 at an upper portion, which is a side into which the dust bag 22 is inserted. The rotating member 32 is rotatable with respect to the dust collecting chamber 12 to the outside, i.e., the front side, and the inside, i.e., the rear side. The position and direction of the rotation member 32 vary depending on the direction of the opening of the dust collecting chamber 12, but the position and direction of the rotation member 32 are not limited to these positions and directions. The rotating member 32 functions as a safety device for preventing the lid 14 from closing the dust collecting chamber 12 in a state where the dust bag 22 is not attached. The rotating member 32 of the present embodiment is used to lock the pocket frame 23 of the dust bag 22 held by the dust bag holding portion 26.

As shown in fig. 1, 4, and 5, the rotating member 32 includes a member body 34 rotatably supported with respect to the body 11. The member body portion 34 is rotatably supported on a shaft support portion 35 of the body portion 11 via a rotation shaft 34 a. The rotating shaft 34a of the present embodiment extends in the left-right direction, but is not limited to this direction. For example, in the case where the rotating member 32 is disposed in the vertical direction, the rotating shaft 34a extends in the vertical direction. Further, a biasing unit 36 is attached to the rotating shaft 34 a. The urging unit 36 urges the rotating member 32 to rotate toward the front side, which is the outer side of the dust collection chamber 12. The urging unit 36 uses a torsion spring in the present embodiment, but is not limited thereto, and a coil spring or the like may be used.

The rotating member 32 includes a sealing restriction portion 38 that restricts sealing of the dust collection chamber 12 by the lid 14. The closing restriction portion 38 protrudes from the member body portion 34, and abuts against the lid body 14 at a position rotated outward, i.e., forward, with respect to the dust collection chamber 12 in a state where the dust collection bag 22 is not attached to the dust collection bag holding portion 26, thereby blocking the closing of the dust collection chamber 12 by the lid body 14. The closing restriction portion 38 of the present embodiment is formed continuously with the upper portion of the member main body portion 34. The closing restriction portion 38 is formed to be bent toward the front side, which is the outer side of the dust collecting chamber 12, with respect to the member body portion 34. Further, the closing restriction portion 38 extends upward from the opening edge of the dust collection chamber 12 of the body portion 11. The position, bending, and other directions of the closing restriction portion 38 vary depending on the arrangement of the rotating member 32, and therefore, the present invention is not limited to this.

The rotating member 32 further includes a load receiving portion 40 below the closing restriction portion 38. The load receiving portion 40 is in contact with a support portion 41 formed in the main body portion 11 in a state where the dust bag 22 is not attached to the dust bag holding portion 26, and thereby receives a force from an upper side, which is a side into which the dust bag 22 is inserted. The load receiving portion 40 protrudes from the member body portion 34 to the outside of the dust collecting chamber 12, i.e., to the front side. The load receiving portion 40 of the present embodiment is formed in a rib shape along the vertical direction, i.e., the direction along the insertion direction of the dust bag 22. In the present embodiment, a pair of the load receiving portion 40 and the support portion 41 is formed so as to be separated from each other in the left-right direction.

The rotating member 32 includes a contact portion 43 at a position opposite to the closing restriction portion 38 with respect to the rotating shaft 34 a. The contact portion 43 is configured to rotate the rotating member 32 toward the rear side, which is the inner side of the dust collecting chamber 12, by coming into contact with the pocket opening frame 23 of the dust collecting bag 22 attached to the dust collecting bag holding portion 26. The contact portion 43 is formed from the member body portion 34 so as to be located on the opposite side, i.e., the lower side, from the closing restriction portion 38. The contact portion 43 extends toward the rear side, which is the inner side of the dust collecting chamber 12, with respect to the rotation shaft 34 a. Further, the contact portion 43 extends along the rotational axis direction of the rotational member 32. Thereby, the rotating member 32 is configured to rotate in the opposite directions of the closing restriction portion 38 side and the contact portion 43 side with the rotating shaft 34a as a fulcrum. The contact portion 43 of the present embodiment is rod-shaped and extends from the member main body portion 34 to the left and right, but is not limited to this configuration and shape, and may be formed to extend only to either the left or the right. In addition, the contact portion 43 of the present embodiment is set closer than the closing restriction portion 38 with respect to the distance in the rotation radial direction of the rotation member 32. The contact portions 43 extend outward of the suction port 9 and the suction port seal 10, i.e., in both the left and right directions. The direction of the position, shape, and the like of the contact portion 43 varies depending on the arrangement of the rotating member 32, and therefore, is not limited thereto. The rotating member 32 has a cutout 44 formed between the left and right contact portions 43 to avoid the suction port 9 and the suction port seal 10.

The rotating member 32 includes a pressing portion 45 protruding toward the rear side, which is the inside of the dust collecting chamber 12. The pressing portion 45 presses the bag opening frame 23 of the dust bag 22 held by the dust bag holding portion 26, and prevents the dust bag 22 from being detached from the dust bag holding portion 26. The pressing portion 45 is formed to protrude from the member main body portion 34 in a rib shape. The pressing portion 45 extends in the left-right direction, but is not limited thereto. The pressing portion 45 is formed at a position close to the rotation shaft 34a with respect to the closing restriction portion 38. In the present embodiment, the pressing portion 45 is formed on the rotating member 32, but the present invention is not limited to this configuration, and a configuration may be adopted in which the pressing portion such as a rib that presses the bag opening frame 23 of the dust collection bag 22 in a state where the dust collection chamber 12 is closed by the lid 14 is formed on the lid 14.

Next, the operation of one embodiment will be described.

In the case where the dust bag 22 is not mounted to the dust chamber 12, the user mounts the dust bag 22 to the dust chamber 12 before starting dust collection. In a state where the dust collecting chamber 12 is not equipped with the dust collecting bag 22, as shown in fig. 1, the rotating member 32 is rotated to the outside, i.e., the front side, with respect to the dust collecting chamber 12 by the urging force of the urging means 36, and the closing restriction portion 38 is positioned in the movable range of the lid body 14 overlapping with the seal member 13 and interfering with the lid body 14, whereby the rotating member 32 abuts against the close portion 15 at the position of the closing restriction portion 38 to hinder the closing of the lid body 14. In this position, the closing restriction portion 38 of the rotation member 32 is not positioned on the mounting path of the dust bag 22 to the dust bag holder 26, and only the contact portion 43 slightly protrudes toward the upper side, which is the mounting side of the dust bag 22 of the dust bag holder 26. Therefore, the upper side of the dust bag holding portion 26 is opened with little obstruction by the rotating member 32.

Therefore, in a state where the user opens the lid 14, as shown in fig. 2, the pocket frame 23 of the dust bag 22 can be easily inserted while being aligned with the dust bag holding portion 26. The positions of both side portions of the pocket frame 23 are regulated by the side regulating portions 27, the positions of the rear side portions of the pocket frame 23 are regulated by the position regulating portions 28, and the pocket frame 23 of the dust bag 22 is inserted between the dust bag holding portions 26 on both sides and the suction port 9. The inserted positions on both sides of the opening 24 of the bag opening frame 23 are in contact with the contact portions 43 on the lower side of the rotating shaft 34a, and the position on the upper side of the rotating member 32 with respect to the rotating shaft 34a is rotated inward, that is, rearward with respect to the dust collection chamber 12 about the rotating shaft 34a by pressing the contact portions 43 against the biasing force of the biasing means 36, and is retracted from the movable range of the lid 14. At this time, since the introduction portion 30 is formed in the position regulating portion 28 above the dust bag 22 inserted in the dust bag holding portion 26, the pocket frame 23 inserted into the dust bag holding portion 26 so as to be inclined toward the inside of the dust chamber 12 with respect to the rotating member 32 is smoothly introduced into the space between the position regulating portion 28 of the dust bag holding portion 26 and the suction port 9.

As shown in fig. 3, when the pocket frame 23 of the dust collection bag 22 is further pushed in and the pocket frame 23 reaches the bottom of the dust collection chamber 12, the portion around the opening 24 of the pocket frame 23 is in close contact with the suction port seal 10, the opening 24 and the suction port 9 are connected in an airtight manner, and the pressing portion 45 of the rotating member 32 presses the pocket frame 23 from above. When the dust bag 22 is held in the dust collection chamber 12 in this manner, the closing restriction portion 38 is retracted out of the movable range of the lid body 14 by being separated from the sealing member 13, and therefore, when the dust collection chamber 12 is closed by the lid body 14, the closing restriction portion 38 does not interfere with the lid body 14, and therefore, the dust collection chamber 12 can be closed by the lid body 14. Therefore, the user turns the lid 14 to close the dust collection chamber 12, and the lid 14 is locked to the main body 11 by the locking unit 16. In this state, the tight part 15 of the lid 14 is pressed against the sealing member 13, and the dust collecting chamber 12 is sealed.

When the user operates the setting unit 8 for setting the start and stop of the electric vacuum cleaner 1 and the electric vacuum cleaner 1 is started, the electric blower 17 operates to generate a negative pressure. The user grips the operation unit 7 and sucks dust on the floor surface together with air through the suction port body 6 and the like. The dust-containing air is sucked from the suction port 9 into the opening 24 of the dust bag 22 attached to the dust chamber 12, and the dust is separated and collected in the filter member 25 of the dust bag 22. The air from which the dust is separated is sucked by the electric blower 17. The air sucked into the electric blower 17 cools the electric blower 17, is discharged from the electric blower 17, and is further discharged to the outside of the cleaner body 2 through the exhaust port 20.

When the dust collection is completed, the user operates the setting unit 8 to stop the operation of the electric vacuum cleaner 1. When the dust bag 22 accumulates a predetermined amount or more of dust or the filter portion 25 is clogged and the suction force of the electric blower 17 is lowered, the user releases the locking of the cover 14 to the main body 11 by the locking means 16, and rotates the cover 14 to open the dust collecting chamber 12. Then, the dust bag 22 is pulled out from the dust bag holding portion 26 and removed from the dust chamber 12 while rotating the rotating member 32 forward against the biasing force, and then the dust bag 22 is discarded together with the dust.

According to the above-described embodiment, at least a part of the rotating member 32 is positioned in the movable range of the lid body 14 in the state where the dust bag 22 is not attached to the dust bag holding portion 26, whereby the lid body 14 can be prevented from being closed in the state where the dust bag 22 is not attached. Therefore, since the user can easily notice that the dust bag 22 is not attached by not closing the lid body 14, it is possible to suppress the electric vacuum cleaner 1 from being operated erroneously in a state where the dust bag 22 is not attached. In addition, in a state where the dust bag 22 is not attached, the rotation member 32 is located outside the dust chamber 12 with respect to the dust bag holder 26 of the dust bag 22 and at a position not obstructing the attachment path of the dust bag 22 with respect to the dust bag holder 26, so that the dust bag 22 can be easily attached to the dust bag holder 26. In the state where the dust bag 22 is attached to the dust bag holding portion 26, the contact portion 43 of the rotating member 32 and the pocket frame 23 of the dust bag 22 come into contact with each other, so that the rotating member 32 rotates and retreats from the movable range of the lid 14 to the inside of the dust chamber 12, and therefore the dust chamber 12 can be closed by the lid 14.

Further, even if the user mistakenly presses the bag opening frame 23 of the dust bag 22 against the rotation member 32 when attaching the dust bag 22, the force from the side of inserting the dust bag 22 into the dust bag holding portion 26 is received by the load receiving portion 40, and therefore the rotation member 32 is less likely to be damaged. In particular, in the case of the dust collecting chamber 12 opened upward, the user can easily press the rotating member 32 into the pocket frame 23 while applying gravity when attaching the dust collecting bag 22, and therefore, the load can be received by the load receiving portion 40, and damage or the like of the rotating member 32 can be suppressed.

Further, since the contact portion 43 of the rotating member 32 extends further outward than the suction port 9, when the dust bag 22 is attached to the dust bag holding portion 26, the contact portion 43 can be easily brought into contact with a position around the opening portion 24 with respect to the pocket frame 23, and the rotating member 32 can be rotated to be easily retracted from the movable range of the lid body 14 to the inside of the dust collecting chamber 12.

Further, since the contact portion 43 and the closing restriction portion 38 located on the opposite sides to each other with the rotation shaft 34a interposed therebetween are located closer to the rotation shaft 34a in the rotation radial direction than the rotation shaft 34a, the range in which the closing restriction portion 38 rotates is set larger than the range in which the contact portion 43 moves due to contact with the pocket frame 23 of the dust bag 22, and the closing restriction portion 38 can be retracted largely to the inside of the dust chamber 12, and the closing restriction portion 38 is located largely to the outside with respect to the dust chamber 12 before the dust bag 22 is attached, so that attachment of the dust bag 22 is not easily hindered.

In the above-described embodiment, the dust collecting chamber 12 having an upper opening is opened and closed by the lid 14, but the present invention is not limited to this configuration, and the present invention is also applicable to a configuration in which the dust collecting chamber 12 having front and left and right openings is opened and closed by the lid 14. Therefore, the direction and position described in the above embodiment are appropriately set according to the installation position of the electric vacuum cleaner 1, the shape of the electric vacuum cleaner 1, and the like.

Several embodiments of the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
