[0010] Hereinafter, a vacuum cleaner 1 according to one embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the overall configuration of the vacuum cleaner 1 will be outlined first, and then the main parts will be described in more detail. In the following description, unless otherwise specified, the positional relationships in the up-down direction, width direction, etc. will be described based on the state in which the vacuum cleaner 1 is erected as shown in FIG.

[0011] <Overall configuration of vacuum cleaner 1>

[0012] As shown in Figs. 1 to 3, the vacuum cleaner 1 is a vacuum cleaner having a stick-shaped (vertical) appearance. The vacuum cleaner 1 is a rechargeable vacuum cleaner equipped with a battery, but may also be a vacuum cleaner that obtains power from an external power source via a power cord. As shown in Fig. 1, the vacuum cleaner 1 includes a vacuum cleaner main body 10, a dust collecting section 20, an extension tube 30 (tube section), and a suction tool 40. The vacuum cleaner 1 may form a vacuum cleaner system S including a base 2 and the like as shown in Figs. 1 to 3.

[0013] The vacuum cleaner main body 10 constitutes the main body of the vacuum cleaner 1 and is the part that exerts suction power to collect dust. Specifically, as described in detail later, the vacuum cleaner main body 10 includes, inside a main body case 100 that forms a housing, an electric blower 16 for sucking in air and generating an airflow, a drive circuit for driving other electronic components, and other components.

[0014] As shown in Figs. 1 to 5, the vacuum cleaner body 10 includes a handle 12 (grip) and an operation unit 14. The handle 12 is a part provided for a user of the vacuum cleaner 1 to grip the vacuum cleaner body 10. That is, the vacuum cleaner 1 is configured so that the user can grip the vacuum cleaner body 10 by, for example, passing the user's fingers, except for the thumb, through an opening provided in the handle 12. The operation unit 14 is for operating the vacuum cleaner 1. The operation unit 14 is for, for example, turning the power on and off. The handle 12 in this embodiment is provided on one side in a direction (short side direction) perpendicular to the longitudinal direction of the vacuum cleaner body 10, and the side on which the handle 12 exists is defined as the front side based on the direction perpendicular to the longitudinal direction of the vacuum cleaner body 10, but when the handle is provided at an end (upper end) of the longitudinal direction of the vacuum cleaner body 10, the direction extending between one end and the other end of the handle is the front-rear direction.

[0015] The dust collection unit 20 is a portion where dust sucked by the vacuum cleaner 1 is collected. The dust collection unit 20 is provided so as to be continuous with the vacuum cleaner body 10. A suction port 22 is provided on the lower end side of the dust collection unit 20. This allows the dust collection unit 20 to suck in dust through the suction port 22.

[0016] 1 to 3, extension tube 30 is a tubular member that detachably connects vacuum cleaner body 10 and suction tool 40. One end of extension tube 30 is shaped so that it can be inserted into suction port 22, and the other end is shaped so that it can be connected to suction tool 40. By connecting vacuum cleaner body 10 and suction tool 40 via extension tube 30, a continuous path from suction tool 40 to vacuum cleaner body 10 can be formed.

[0017] As shown in FIG. 1 and FIG. 2, the suction tool 40 includes a suction tool body 42 and a joint part 44. The suction tool 40 includes a cleaning body (not shown) and a cleaning body drive mechanism (not shown) inside the suction tool body 42. The suction tool body 42 is a part that is placed on the floor during cleaning, and has a shape that is long in the left-right direction compared to the front-rear direction in which the user operates during cleaning. Inside the suction tool body 42, a suction space is formed with an open end on the floor side for sucking in air and dust from the outside. The joint part 44 is attached to the suction tool body 42 so as to be rotatable within a predetermined rotation range (front-rear and left-right directions). The joint part 44 is a part to which the end of the extension tube 30 described above is connected. The joint part 44 is cylindrical, and the internal space is connected to the suction space.

[0018] The electric vacuum cleaner 1 is roughly configured as described above. The electric vacuum cleaner 1 has a characteristic structure in the structure of the vacuum cleaner body 10, centering on the dust collection unit 20 and the structure in the vicinity thereof. The characteristic structure of the vacuum cleaner body 10, centering on the dust collection unit 20, etc., will be described in more detail below.

[0019] <Characteristic configuration of the vacuum cleaner body 10> 1 etc., the vacuum cleaner body 10 has a suction port 22 on one side (lower side) in the up-down direction (first direction). The vacuum cleaner body 10 also has a handle 12 at a position opposite (upper side) to the suction port 22 in the up-down direction when in the up-down position. In other words, the vacuum cleaner body 10 has the suction port 22 on one side in the longitudinal direction (first direction) and the handle 12 on the other side in the longitudinal direction.

[0020] As shown in Figs. 4 to 8, the vacuum cleaner body 10 has a dust collection section 20 at a position between the handle 12 and the suction port 22 in the up-down direction (longitudinal direction). The dust collection section 20 has a dust collection space 24 inside the vacuum cleaner body 10, which is provided so as to communicate with the suction port 22. Furthermore, as shown in Fig. 5, an electric blower 16 is provided inside the vacuum cleaner body 10 at a position above the dust collection space 24 of the dust collection section 20 in the up-down direction. Thus, the vacuum cleaner body 10 can apply negative pressure to the suction port 22 by operating the electric blower 16.

[0021] As shown in FIG. 5, the vacuum cleaner body 10 contains a battery 18 inside. The battery 18 is electrically connected inside the vacuum cleaner body 10 so as to supply power to the electric blower 16. The battery 18 can be provided at any suitable location inside the vacuum cleaner body 10, and may be located, for example, above or behind the electric blower 16. In the vacuum cleaner body 10 of this embodiment, the battery 18 is located above the electric blower 16. The vacuum cleaner body 10 also has a control board 17 on which a control unit for controlling the electric vacuum cleaner 1 is mounted. The control board 17 is located on the front side in line with the battery 18, but may be located above or behind the battery 18. The control board 17 is wired to the operation unit 14, the electric blower 16, and the battery 18.

[0022] 5, a wiring 18a is connected to the control board 17 in order to supply power from the battery 18 to the suction tool 40. The wiring 18a is arranged to extend to the suction port 22 side via the handle 12 and the wiring housing 25 on the front side of the dust collection space 24. By connecting the extension tube 30 to the suction port 22, the extension tube 30 is electrically connected to a wiring (not shown) arranged inside the extension tube 30 via a terminal (not shown) provided on one end side of the extension tube 30 and the suction tool 22 of the vacuum cleaner body 10. In addition, a terminal (not shown) is provided on the other end side of the extension tube 30 and the suction tool 40, and by connecting the extension tube 30 and the suction tool 40, both are electrically connected. Therefore, by connecting one end side of the extension tube 30 to the suction port 22 and connecting the other end side of the extension tube 30 to the suction tool 40, power can be supplied from the battery 18 to the suction tool 40. This allows the drive unit to be operated when the suction tool 40 includes a drive unit for rotating the cleaning body (rotary brush). The wire housing 25 communicates with the handle 12. The wire housing 25 is configured so that its left-right width is narrower than the dust collection space 24. Preferably, the wire housing 25 extends to the suction port 22 side while maintaining the left-right width of the handle 12, and can reduce unevenness in design. One end of the handle 12 is connected to a position above the electric blower 16 in the longitudinal direction (first direction) of the vacuum cleaner body 10, and the other end of the handle 12 is connected to a position below the electric blower 16 in the longitudinal direction (first direction) of the vacuum cleaner body 10 and is connected to the wire housing 25. In this way, it is possible to avoid wiring around the electric blower 16, and thus to achieve compactness.

[0023] As described above, the suction port 22 is provided on one side (lower side) in the up-down direction (first direction) of the vacuum cleaner body 10. The suction port 22 is open so that the suction tool 40 can be directly connected or the extension tube 30 connected to the suction tool 40 can be connected. As shown in Fig. 5, when a central axis C1 extending along the up-down direction in the dust collection space 24 provided inside the dust collection section 20 is assumed, the suction port 22 is provided at a position on the front side in the front-rear direction (second direction) based on the central axis C1 in a direction (short direction) perpendicular to the longitudinal direction of the vacuum cleaner body 10.

[0024] The dust collection space 24 is a space for collecting dust sucked through the suction port 22. The dust collection space 24 is constituted by a hollow space provided inside the dust collection unit 20 described above. The dust collection space 24 is located inside the vacuum cleaner body 10, below the electric blower 16. As shown in Figs. 8 and 9, the dust collection space 24 has an opening 24a that is open toward the rear side (back side) in the front-rear direction of the vacuum cleaner body 10. The dust collection space 24 may directly accommodate the dust sucked through the suction port 22, but in this embodiment, it is capable of accommodating a paper (cloth, nonwoven fabric) pack (not shown) attached to a pack connection part 28b provided at the end of the air passage configuration part 28 described later. As a result, the dust collection space 24 is capable of collecting dust in a paper pack set inside through the opening 24a.

[0025] The opening / closing part 26 is for opening and closing the dust collection space 24. Therefore, the opening / closing part 26 is located on the rear side (back side) in the front-rear direction in the vacuum cleaner body 10. As long as the opening / closing part 26 can open and close the dust collection space 24, it can be, for example, a lid type that can be attached and detached to the opening 24a, a shutter type that opens and closes the opening 24a with an action such as sliding, or a type that can be opened and closed by pivoting the upper or lower end of the opening / closing part 26 to be rotatably supported by a pivot shaft. In this embodiment, the opening / closing part 26 is a lid type that can be attached and detached to the opening 24a.

[0026] As shown in FIG. 5 to FIG. 9, the opening / closing part 26 has a first engaging part 26x that can be engaged with a first engaged part 24x provided on the dust collection space 24 side, and a second engaging part 26y that can be engaged with a second engaged part 24y provided on the dust collection space 24 side. The first engaging part 26x and the first engaged part 24x are each located on one side in the vertical direction (lower side in the illustrated example), and the second engaging part 26y and the second engaged part 24y are each located on the other side in the vertical direction (upper side in the illustrated example). The first engaged part 24x and the second engaged part 24y provided on the dust collection space 24 side can each be configured, for example, by a concave part, a convex part, a notch, a piece-like part, or the like. Also, the first engaging part 26x and the second engaging part 26y can each be configured, for example, by a convex part, a concave part, a piece-like part, or the like that can be engaged with the first engaged part 24x or the second engaged part 24y.

[0027] In this embodiment, the first engaging portion 26x is configured by a convex portion formed to protrude in the vertical direction at the lower end side of the opening / closing portion 26, and the first engaged portion 24x is configured by a concave portion formed to be able to receive the first engaging portion 26x. The second engaging portion 26y is configured by a slide piece that slides in the vertical direction by a sliding operation at the upper end side of the opening / closing portion 26. The second engaged portion 24y is configured by a concave portion that can receive the slide piece that constitutes the second engaging portion 26y when the opening / closing portion 26 is attached to close the opening 24a of the dust collection space 24. As a result, the vacuum cleaner body 10 can engage the opening / closing part 26 at the lower end by inserting the first engagement portion 26x provided on the lower end side of the opening / closing part 26 into the first engaged portion 24x, and when the opening / closing part 26 is attached to cover the opening 24a, the second engagement portion 26y can be slid at the upper end side of the opening / closing part 26 to engage the second engagement portion 26y with the second engaged portion 24y, thereby fixing the opening / closing part 26 to the vacuum cleaner body 10.

[0028] The engagement structure (first engaged portion 24x, second engaged portion 24y) may be released by pressing a push button (an example of an operating piece) instead of by sliding a slide piece (an example of an operating piece). In other words, the operating piece may be switchable between a locked state in which the opening / closing unit 26 is locked in a closed state and a released state in which the locked state of the opening / closing unit 26 is released. The operating piece may be present at either the upper end side or the lower end side of the opening / closing unit 26 in the first direction, and in the case where the upper or lower end of the opening / closing unit 26 is configured to be rotatably supported by a rotating shaft, the operating piece is present on the opposite side of the rotating shaft in the first direction.

[0029] In addition, the back side of the vacuum cleaner body 10 has a protruding portion 9 protruding outward. As a result, when the rear side of the vacuum cleaner 1 is placed so that it contacts a wall or a floor surface, the vacuum cleaner body 10 is separated from the wall or floor surface by the length of the protruding portion 9 in the front-rear direction (the thickness of the protruding portion 9), so that the above-mentioned operating piece can be prevented from being operated unintentionally. The protruding portion 9 is preferably provided on the other side (upper side) of the opening / closing portion 26 in the first direction, and more preferably, is provided at the upper end in the first direction. In addition, the protruding portion 9 preferably protrudes rearward from the operating piece in the front-rear direction. In addition, although not an essential configuration, the protruding portion 9 preferably has a rubber member 9a for preventing slipping on the wall or floor surface. When the vacuum cleaner 1 is placed on the floor surface, the back side of the vacuum cleaner body 10 is supported by the protruding portion 9 and the lower end in the first direction.

[0030] As shown in FIG. 5 and other figures, the air passage forming section 28 is a portion forming an air passage that communicates between the suction port 22 and the dust collection space 24. The air passage forming section 28 has a communication port 28a at an end opposite to the suction port 22 in the up-down direction (first direction). The communication port 28a is provided with a valve body 28e that opens the communication port 28a by suction force and closes the communication port 28a when suction is stopped. The communication port 28a is located at a position offset in the front-rear direction from the suction port 22. The center of the suction port 22 (the central axis C2 that passes through the center of the suction port 22 and extends in the up-down direction) is located forward in the front-rear direction compared to the center of the communication port 28a (the central axis C3 that passes through the center of the communication port 28a and extends in the up-down direction). In order to communicate between the suction port 22 and the communication port 28a in such a positional relationship, the air passage forming section 28 has an inclined portion 28x that is inclined toward the front in the front-rear direction as it approaches the lower side in the up-down direction. That is, air passage forming portion 28 is inclined toward the rear side in the front-rear direction toward dust collection space 24. In addition, since opening / closing portion 26 is provided on the upper side in the vertical direction relative to communication opening 28a, inclined portion 28x of air passage forming portion 28 is inclined toward opening / closing portion 26 toward the upper side in the vertical direction.

[0031] As shown in FIG. 10 and other figures, the air passage configuration section 28 has a pack connection section 28b at the end on the communication port 28a side. The pack connection section 28b is a section to which a paper pack (not shown) disposed inside the dust collection space 24 is connected. The pack connection section 28b has a cylindrical section 28c and a pack engagement section 28d. The cylindrical section 28c is a cylindrical section provided so as to protrude toward the inside of the dust collection space 24. The cylindrical section 28c is insertable into the opening of the paper pack. The pack engagement section 28d holds the paper pack by engaging with the end of the paper pack when the cylindrical section 28c is inserted into the opening of the paper pack. The pack engagement section 28d may be any type that can engage with the paper pack, and may be, for example, a clip-shaped section that holds the paper pack by pinching it, or a hook-shaped section that can hook and engage the end of the paper pack. In the illustrated example, the pack engagement section 28d is a hook-shaped section.

[0032] <Effects obtained by vacuum cleaner 1> The effects and the like obtained by the vacuum cleaner 1 exemplified in the above embodiment will be described below.

[0033] (1) The electric vacuum cleaner 1 according to one embodiment of the present invention described above has a vacuum cleaner body 10 equipped with a suction port 22 provided on one side in a first direction and a handle 12 provided on the other side in the first direction. The vacuum cleaner body 10 has an electric blower 16 that applies negative pressure to the suction port 22 and a dust collection space 24 for collecting dust, and has an opening / closing part 26 for opening and closing the dust collection space 24 at the rear side in the front-to-rear direction perpendicular to the first direction.

[0034] As described above, the vacuum cleaner 1 is configured such that the opening / closing part 26 for opening and closing the dust collection space 24 is provided at the rear in the front-to-rear direction, which allows the vacuum cleaner body to be designed with a degree of freedom not attained by conventional techniques, as compared with a configuration in which the opening / closing part 26 is provided at the front. Therefore, by configuring the vacuum cleaner 1 as described above in (1), the degree of design freedom can be improved.

[0035] (2) In the electric vacuum cleaner 1 relating to (1) above, the vacuum cleaner body 10 has an air passage forming section 28 that connects the suction port 22 and the dust collection space 24, and the air passage forming section 28 has a communication port 28a at an end opposite the suction port 22 in the first direction, and the center of the suction port 22 is located forward in the fore-and-aft direction compared to the center of the communication port 28a.

[0036] As described above in (2), the electric vacuum cleaner 1 is configured such that the center of suction port 22 is located forward of the center of communication port 28a, thereby making it possible to prevent dust from flowing back toward the suction port inside dust collection space 24. In particular, when the user holds vacuum cleaner body 10 so that the first direction is along the up-down direction, it is easy to prevent dust from flowing back inside dust collection space 24.

[0037] (3) In the electric vacuum cleaner 1 relating to (1) or (2) above, the vacuum cleaner body 10 has an air passage forming section 28 that connects the suction port 22 and the dust collection space 24, and the air passage forming section 28 is inclined toward the opening / closing section 26 as it moves toward the other side of the first direction.

[0038] By configuring the vacuum cleaner 1 to be inclined toward the opening / closing part 26 toward the other side in the first direction as described above in (3), it is possible to prevent dust from flowing back toward the suction port inside the dust collection space 24. In particular, when the user holds the vacuum cleaner body 10 so that the first direction is along the up-down direction, it is easy to prevent dust from flowing back inside the dust collection space 24.

[0039] (4) In the electric vacuum cleaner 1 relating to any of (1) to (3) above, the vacuum cleaner body 10 has a dust collection space 24 below the electric blower 16, and has a battery 18 on one side of the electric blower 16 in the first direction or on the rear side of the electric blower 16 in the front-to-rear direction, the handle 12 is arranged in front of the electric blower 16 in the front-to-rear direction, and the suction port 22 is located on the front side in the front-to-rear direction based on a central axis C1 along the first direction in the dust collection space 24, and is connectable to an extension tube 30 connected to a suction tool 40.

[0040] With the configuration of (4) above, the center of gravity of the vacuum cleaner 1 is located on the suction port 22 side of the vacuum cleaner body 10, and the distance between the center of gravity and the gripping position is short when the handle 12 is gripped. This allows the vacuum cleaner 1 to be highly maneuverable when the handle 12 is gripped.

[0041] (5) In the electric vacuum cleaner 1 relating to any one of (1) to (4) above, the vacuum cleaner body 10 is provided with a battery 18 and has wiring 18a electrically connected to the battery 18 to supply power from the battery 18 to the suction tool 40 communicating with the vacuum cleaner body 10, the vacuum cleaner body 10 has a wiring accommodating section 25 that accommodates the wiring 18a passing through the handle 12, and the wiring accommodating section 25 is located in front of the dust collection space 24 in the front-to-rear direction.

[0042] By configuring the vacuum cleaner 1 as described above in (5), it is possible to avoid wiring around the electric blower 16, and therefore it is possible to realize a compact design.

[0043] (6) In the electric vacuum cleaner 1 according to any one of (1) to (5) above, an operating piece is provided for switching between a locked state in which the opening / closing unit 26 is locked in a closed state and an unlocked state in which the locked state of the opening / closing unit 26 is unlocked, and the vacuum cleaner body 10 has a protrusion that protrudes rearward in the front-to-rear direction on the other side of the opening / closing unit 26 in the first direction.

[0044] By configuring the vacuum cleaner 1 as described above in (6), when the vacuum cleaner 1 is placed on a wall or floor, it is possible to prevent the operating piece from being unintentionally operated and the opening / closing part 26 from being opened unintentionally.

[0045] The present invention is not limited to the above-mentioned embodiments and modifications, and other embodiments may be possible within the scope of the claims. The components of the above-mentioned embodiments may be arbitrarily selected and combined. Any component of the embodiment may be arbitrarily combined with any component described in the means for solving the problems or any component that embodies any component described in the means for solving the problems.
