JP 2006-34720 A (FIGS. 1 to 3 and FIG. 9)

  As described above, the portable vacuum cleaner disclosed in Patent Document 1 has a dust box that is detachably attached to the front portion (dust collection chamber) of the cleaner body, and the entire side surface of the dust box is attached to the side wall of the body case (dust collection). It is configured to be received by the side wall of the chamber. Further, a filter (air inlet filter) disposed at the suction port on the electric blower side of the dust collection chamber is also detachably mounted from the mounting port of the dust collection chamber. However, in the case of a portable vacuum cleaner, the main body of the vacuum cleaner is small and the attachment port of the dust collection chamber is also narrow and often narrower than the width of the hand. There was a problem that it was difficult to perform because of being obstructed by the (side wall of the dust collecting chamber). In particular, those that can stand on their own as shown in Patent Document 1 become more difficult because the top surface of the dust collection chamber on which the filter is mounted is difficult to see in the self-standing state.

  In addition, the dust collection chamber to which the dust box is attached has a box shape, so if dust is spilled into the dust collection chamber when the dust box that has accumulated dust is removed from the dust collection chamber, it will be removed. It was not easy to take it out of.

  In addition, since a rechargeable battery, which is a power source for driving, is built in the handle, a heavy battery is positioned at the top in a self-supporting state, so the center of gravity is high and the floor surface in a self-supporting state It ’s easier to tip over when it ’s tilted or something hits it. In addition, since the handle position and the center of gravity are close to each other, the load applied to the hand is increased due to the lever principle when the cleaner body is tilted backward.

  Accordingly, the present invention has been made to solve such a problem, and the maintainability of the filter detachably attached to the electric blower side suction port of the dust collection chamber is improved and the filter spills into the dust collection chamber. An object of the present invention is to provide a portable vacuum cleaner that can easily take out dust.

  It is another object of the present invention to provide a portable vacuum cleaner that can improve stability in a self-supporting state and can reduce a load applied to a hand during use.

  In order to achieve the above-described object, the invention according to claim 1 of the present application is formed in a dust collector chamber in which a dust collection chamber is disposed at a front portion and an electric blower is built in a rear portion, and the dust collection chamber. A dust box that is detachably mounted from the mounting port, and a filter that is detachably mounted from the mounting port of the dust collection chamber to the suction port on the electric blower side of the dust collection chamber, In addition, it is characterized in that it is formed by cutting out in a substantially arc shape across both side walls of the dust collection chamber.

  The invention according to claim 2 is characterized in that a suction nozzle that communicates with the dust collection chamber and is removably mounted with a floor suction tool is provided at the end of the vacuum cleaner body on the dust collection chamber side. Provided with a handle at the electric blower side end of the machine body, the vacuum cleaner body can stand upright above the floor suction tool with the floor suction tool attached to the suction nozzle It is characterized by comprising.

  According to a third aspect of the present invention, the battery serving as a driving power source for the electric blower is positioned in a substantially lateral direction of the electric blower in a state where the vacuum cleaner main body stands and stands above the floor suction tool. It is characterized by arranging in this way.

  The invention according to claim 4 is arranged in such a manner that the vacuum cleaner main body is tilted with the lower side of the battery facing outward and the upper side facing inward with the floor suction tool standing and self-supporting. And the said vacuum cleaner main body was formed in the shape where the upper part side tapers, It is characterized by the above-mentioned.

  The invention according to claim 5 is characterized in that, in a state where the vacuum cleaner main body stands up above the floor suction tool and is self-supporting, the handle is formed in a curved shape almost directly above the battery. It is what.

  According to a sixth aspect of the present invention, in the state where the vacuum cleaner body stands up above the floor suction tool and is self-supporting, the upper end portion of the handle is positioned substantially directly above the battery and protrudes downward. A convex portion is formed.

  According to the invention of claim 1 of the present application, the mounting port of the dust collection chamber to which the dust box is detachably mounted is formed by cutting out the substantially circular arc shape on both side walls of the dust collection chamber. Even if it is a narrow attachment port that cannot be inserted into the fist of the hand, which is unique to vacuum cleaners, the index finger should be placed so that the back side of the hand is directed to the attachment port that is cut out in a substantially arc shape across the side walls of the dust collection chamber. The filter can be easily attached and detached using a middle finger or the like. Therefore, the maintainability of the filter detachably attached to the electric blower side suction port of the dust collection chamber is improved. Also, dust spilled into the dust collection chamber can be easily taken out because the mounting port of the dust collection chamber is cut out in a substantially arc shape across both side walls of the dust collection chamber.

  In the case where the vacuum cleaner body is configured to be able to stand on its own above the floor suction tool as in the second aspect of the invention, the top surface of the dust collection chamber in which the filter is mounted can be seen in the standing state. Since it is difficult, the above-described effect is particularly effective.

  According to the third aspect of the present invention, the battery serving as the power source for driving the electric blower is positioned substantially in the lateral direction of the electric blower in a state where the vacuum cleaner main body stands and stands above the floor suction tool. As a result of the arrangement, the position of the center of gravity is lowered as compared with that incorporated in the handle as described in Patent Document 1 described above, so that stability in a self-supporting state is improved. In addition, since the handle position and the center of gravity are far from each other, when the cleaner body is tilted backward, the load applied to the hand is reduced due to the principle of the lever, and the usability is improved.

  According to the invention described in claim 4, in a state where the vacuum cleaner body stands up above the floor suction tool and is self-supporting, the battery is disposed so that the lower side is inclined outward and the upper side is inclined inward. Since the upper part of the vacuum cleaner main body is tapered, the upper side of the vacuum cleaner main body is tapered, and the center of gravity of the vacuum cleaner main body is further lowered by the thicker lower part of the vacuum cleaner main body. And usability is further improved.

  According to the fifth aspect of the present invention, the handle is formed in a curved shape facing substantially directly above the battery in a state where the vacuum cleaner main body stands up above the floor suction tool and is self-supporting. The curved handle can be easily held by hand, and the heavy battery is almost directly under the handle, so that the main body of the vacuum cleaner does not shake when lifted and can be lifted stably.

  According to the sixth aspect of the present invention, in a state where the vacuum cleaner main body stands up above the floor suction tool and is self-supporting, the upper end portion of the handle is positioned substantially directly above the battery and protrudes downward. By forming the part, the convex part hits the little finger while holding the handle with the hand and the hand does not move, so the stability during carrying and use is improved, and the heavy battery is almost the same as the convex part Since it comes directly under, the main body of the vacuum cleaner shakes later when it is lifted, so that the finger and the convex part are not deteriorated, and it can be lifted more stably.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a side view of a portable vacuum cleaner according to an embodiment of the present invention in a self-supporting state, FIG. 2 is a longitudinal sectional view showing an internal configuration thereof, and FIG. 3 is a side view of a state in which the dust box is removed. is there.

  The portable vacuum cleaner 1 according to the present embodiment performs cleaning by lifting the vacuum cleaner body with one hand and moving the body itself with one hand. The floor suction tool 3 detachably attached to the front end (lower end in the self-standing state in FIGS. 1 to 3) and the rear end (upper end in the self-standing state in FIGS. And a curved handle 4 formed.

  As shown in FIG. 2, the vacuum cleaner main body 2 has a dust collection chamber 5 disposed in the front portion (lower portion in the self-standing state of FIG. 2), communicates with the dust collection chamber 5, and has a floor suction tool 3. A suction nozzle 6 that is detachably mounted is provided in a protruding manner, and an electric blower 7 and a rechargeable battery 8 that is a driving power source are built in a rear portion (upper portion in a self-standing state in FIG. 2).

  A dust collection dust box 10 is detachably attached to the dust collection chamber 5 from a mounting opening 9 formed in the dust collection chamber 5. Further, the suction port 11 on the electric blower 7 side of the dust collecting chamber 5 is provided with an air inlet filter 12 that prevents dust leaked from the dust box 10 from being sucked to the electric blower 7 side. The air inlet filter 12 is also detachably mounted from the mounting port 9 of the dust collecting chamber 5.

  As shown in FIG. 3, the mounting port 9 of the dust collection chamber 5 is formed by cutting out a substantially arc shape across both side walls of the dust collection chamber 5. Specifically, a first arc 13a cut out along the suction port 11 on the electric blower 7 side on the rear end (upper end in the self-standing state of FIG. 3) side of the mounting port 5 and the front end ( In the self-supporting state of FIG. 3, it is formed by two arcs of a second arc 13b reaching from the lower end) to both ends of the first arc 13a. The extension line of the second arc 13b is curved in a substantially S shape and continues to the handle 4.

  As shown in FIG. 1, the dust box 10 is mounted on the mounting port 9 of the dust collection chamber 5 formed by cutting out the both side walls in a substantially arc shape as described above, with both side surfaces exposed. The dust box 10 is a resin dust collecting container, and as shown in FIG. 2, the dust box 10 has a small opening 10a corresponding to the suction port 6a of the suction nozzle 6 in the mounted state, and an electric blower 7 to which the air inlet filter 12 is mounted. A side corresponding to the suction port 11 on the side is greatly opened, and a bowl-shaped dust filter 14 is configured to be opened and closed by a hinge 15 in the opening 10b.

  The dust filter 14 is integrally configured by attaching the nonwoven fabric 16 to the ventilation port of the dust filter packing 17 by sewing or the like. A coiled spring 18 is attached as a vibrating body to the bottom frame 17a of the dust filter packing 17 to which the nonwoven fabric 16 is attached.

  On the other hand, the portable vacuum cleaner 1 according to the present embodiment has the floor suction tool 3 mounted on the suction nozzle 6 integrally projecting from the vacuum cleaner body 2 as described above, as shown in FIGS. As shown in FIG. 3, the cleaner body 2 is configured to be able to stand on its own in a state where it stands up above the floor suction tool 3.

  The suction nozzle 6 is a cylindrical body projecting a predetermined length from the front end of the vacuum cleaner body 2, and a nozzle suction port 6 b that is cut obliquely is formed at the tip, and a corner portion such as a floor and a wall or a gap is formed. Used when cleaning.

  On the other hand, the floor suction tool 3 is a substantially T-shaped suction tool in plan view, and is a hollow shape into which the suction nozzle 6 is inserted by being connected to the casing 19 extending in the width direction and the central rear end of the casing 19. The connection vent 20 is provided. A suction port 21 extending in the width direction is formed on the front bottom surface of the casing 19. A rotating brush 22 is provided in the casing 19 so as to face the suction port 21. The rotary brush 22 is rotationally driven by a brush motor 23 built in the casing 19 and can contact the floor surface via the suction port 21 to scoop up dust and efficiently suck in dust.

  The connection vent 20 is a hollow body that communicates with the suction port 21 via the casing 19 and has a length substantially the same as that of the suction nozzle 6 on the main body 2 side, and its front end is connected to the casing 19 so as to be rotatable up and down. As a result, it swings up and down around the front end. Accordingly, the angular position of the casing 19 changes in the vertical direction with respect to the main body 2. Therefore, even if the main body 2 tilts backward, the suction port 21 (rotating brush 22) is not separated from the floor surface.

  In addition, the floor suction tool 3 includes, for example, a charging terminal (not shown) that is electrically connected to the rechargeable battery 8, and the charging terminal is connected to an external power source. By being connected to a power supply side terminal (not shown), it is configured to be able to be charged while maintaining an independent state.

  On the other hand, the electric blower 7 faces the suction port 12 of the dust collection chamber 5 and sucks air 24 from the suction nozzle 6 and the floor suction tool 3 through the dust collection chamber 5 and the suction fan 24. The suction motor 25 is configured to rotate the fan 24. The suction fan 24 has a larger diameter than the suction motor 25.

  As shown in FIG. 2, the rechargeable battery 8 serving as a power source for driving the suction motor 25 and the brush motor 23 of the electric blower 7 is disposed so as to be positioned substantially in the lateral direction of the electric blower 7. Has been.

  Further, the rechargeable battery 8 is disposed so that the lower side faces outward (back side) and the upper side faces inward, thereby forming the cleaner body 2 in a shape in which the upper side is tapered. is doing. In this arrangement, the difference between the diameters of the suction fan 24 and the motor 25 of the electric blower 7 is effectively used, and the arrangement is inclined from the suction fan 24 side having a larger diameter to the motor 25 side having a smaller diameter. is there.

  Further, on the outer surface of the cleaner body 2 corresponding to the arrangement position of the rechargeable battery 8, as shown in FIGS. 1 and 3, a plurality of air for discharging the air sucked by the suction fan 24 to the outside. An exhaust hole 26 is formed.

  On the other hand, the handle 4 is formed in a shape that is curved in a self-standing state from the upper end on the front surface side of the cleaner body 2 toward almost directly above the rechargeable battery 8. Further, a convex portion 27 is formed at the upper end portion of the handle 4 so as to be located almost directly above the rechargeable battery 8 and project downward.

  On the surface of the handle 4 on the cleaner body 2 side, a power switch 28 for operating the portable vacuum cleaner 1 is provided. The power switch 28 is configured to be able to be switched in, for example, two stages. When the one-stage switch is turned on, the rechargeable battery 8 and the motor 25 of the electric blower 7 are electrically connected, and the floor switch In the state where the suction tool 3 is mounted, the rechargeable battery 8 and the brush motor 23 are electrically connected when the one-step switch is turned on.

  In the above configuration, the user lifts the handle 4 of the portable vacuum cleaner 1 in a self-supporting state by holding it with one hand, and further turns on the power switch 28 to move the portable vacuum cleaner 1 while sucking the floor. Cleaning can be performed by sucking dust from the tool 3.

  That is, when the power supply switch 28 is turned on in a state where the floor suction tool 3 is attached to the vacuum cleaner body 2, the suction motor 25 is driven, the suction fan 24 is rotated, and the fan 24 An air flow from the front to the rear is generated. As a result, an air flow (suction force) from the suction port 21 of the floor suction tool 3 into the dust collection chamber 5 is generated, and the floor suction tool 3 is landed on the floor surface, thereby allowing dust on the floor surface to be collected. Is sucked in from the suction port 21, passes through the casing 19 and the connection vent 20 (inside the suction nozzle 6), is captured by the dust filter 14 of the dust box 10 attached to the dust collection chamber 5, and is captured in the dust box 10. Can be stored. The air after the dust is removed is discharged out of the machine from the exhaust hole 26 of the cleaner body 2 while cooling the suction motor 25 and the rechargeable battery 8. Further, the dust accumulated in the dust box 10 can be discarded by removing the dust box 10 from the cleaner body 2.

  Further, when the power switch 28 is turned on in the state where the floor suction tool 3 is mounted, the rechargeable battery 8 and the brush motor 23 of the floor suction tool 3 are electrically connected, and the brush The motor 23 is driven and the rotary brush 22 is driven to rotate. In this state, when the floor suction tool 3 is landed on the floor surface, the rotary brush 22 scoops up the dust on the floor surface, and the dust is sucked better.

  On the other hand, when the floor suction tool 3 is removed from the cleaner body 2, the suction nozzle 6 appears. In this state, by turning on the power switch 28, dust can be sucked from the nozzle suction port 6b of the suction nozzle 6. Thereby, the dust collected in the corner of the floor can be satisfactorily sucked by arranging the suction port 6b of the suction nozzle 6 along the corner of the floor.

  If cleaning as described above is repeated, dust adheres to the air inlet filter 12 and becomes clogged. Therefore, it is necessary to periodically remove the air inlet filter 12 and perform maintenance.

  At the time of this maintenance, the attachment port 9 of the dust collection chamber 5 is formed by cutting out substantially arc-shaped over both side walls of the dust collection chamber 5, so that the entire hand, which is peculiar to a portable vacuum cleaner, cannot be inserted. Even with a narrow attachment port, the air inlet filter 12 is attached to the attachment port 9 that is cut out in a substantially arc shape across the both side walls of the dust collecting chamber 5 by using the index finger, the middle finger, etc. It can be easily attached and detached.

  Therefore, the maintainability of the air inlet filter 12 is improved. Also, dust spilled into the dust collection chamber 5 is easy to take out because the mounting port 9 of the dust collection chamber 5 is cut out in a substantially arc shape across both side walls of the dust collection chamber 5.

  In the case where the vacuum cleaner body 2 is configured so as to be able to stand on its own above the floor suction tool 3 as in the present embodiment, the ceiling of the dust collection chamber 5 to which the air inlet filter 12 is mounted in the standing state. Since the surface is difficult to see, the above-described effects are particularly effective.

  Further, when cleaning is performed, relatively large dust among the sucked dust is collected in the dust box 10, but a part of the fine dust adheres to the nonwoven fabric 16 of the dust filter 14. Previously, dust was removed by removing the dust filter from the dust box and shaking the dust filter. It was not possible to remove dust cleanly.

  Therefore, in this embodiment, as described above, the spring 18 is attached as a vibrating body to the dust filter packing 17 to which the nonwoven fabric 16 is attached. The spring 18 is pulled in the direction of the arrow shown in FIG. 4A and extended as shown in FIG. The fine dust that enters can be efficiently removed. As shown in FIG. 4C, the spring 18 can be flipped back and forth or left and right to impart vibration to the nonwoven fabric 16 of the dust filter 14. When dust is removed in this way, the fine dust adheres to the non-woven fabric 16 of the dust filter 14 and accumulates at the bottom of the dust box 10. Thereafter, the dust filter 14 attached via the hinge 15 is lifted up to lift the dust filter 14 shown in FIG. The dust box 10 may be thrown away by opening the opening 10b of the dust box 10 as shown in FIG. As the vibrating body, the spring 18 is preferable because it can efficiently vibrate, but other vibrating bodies can also be used.

  In this way, fine dust that has entered the eyes of the nonwoven fabric 16 of the dust filter 14 can be efficiently removed with a simple configuration in which a vibrating body is provided on the dust filter packing 17 to which the nonwoven fabric 16 of the dust filter 14 is attached.

  Moreover, since this portable vacuum cleaner 1 can be made to stand independently by making the casing 19 of the floor suction tool 3 land on the floor surface, when the portable vacuum cleaner 1 is not used, the portable vacuum cleaner 1 is made to stand on its own. If so, the space occupied by the portable vacuum cleaner 1 can be reduced. Moreover, since the casing 19 is landing on the floor surface in the self-supporting state, it is possible to easily shift to the cleaning operation.

  In this embodiment, since the rechargeable battery 8 is arranged so as to be positioned substantially in the lateral direction of the electric blower 7 in the above-described self-supporting state, compared to a battery built in a handle as described in Patent Document 1 of the related art. Since the position of the center of gravity is lowered, the stability in an independent state is improved.

  Further, since the position and the center of gravity of the handle 4 are far from each other, when the cleaner body 2 is tilted rearward, the load applied to the hand is reduced by the lever principle and the usability is improved.

  Furthermore, in the self-supporting state, the rechargeable battery 8 is arranged so that the lower side is inclined outward and the upper side is inclined inward, and the cleaner body 2 is formed in a shape in which the upper side is tapered. Since the upper side of the cleaner body 2 in the state is tapered and the lower side is thicker, the center of gravity of the cleaner body 2 as a whole is further lowered, so that the above-described stability and usability are further improved.

  In addition, since the handle 4 is formed in a curved shape so as to be almost directly above the rechargeable battery 8 in a self-supporting state, the curved handle 4 can be easily held by the hand in a self-supporting state, and the heavy charging is performed. Since the battery 8 is almost directly below the handle 4, there is little swing of the cleaner body 2 when it is lifted, and it can be lifted stably.

  Furthermore, a convex portion 27 is formed on the upper end portion of the handle 4 in a self-supporting state so as to be positioned almost directly above the rechargeable battery 8 and project downward. Since the hand 27 does not slip out of hand, stability during carrying and use is improved, and the heavy-weight rechargeable battery 8 is almost directly under the convex part, so that the vacuum cleaner body 2 swings back when lifted. As a result, it is possible to lift the hand more stably without causing the hand fingers and the convex portion 27 to be hung.
