As shown in FIG. 4, the stand upper part 51 is assembled so as to enclose a part (upper side) of the dust container 54, and the dust container 54 is removably fixed. The stand upper part 51 is a frame with an open top and bottom, and the dust container 54 is a square pyramid-shaped container with an open top and narrowing downward. The dust container 54 is inserted from the bottom side of the stand upper part 51. In the present embodiment, the stand portion 50 has a square columnar shape, but it may also have a columnar shape. In the case of a columnar shape, the stand upper part 51 is a columnar frame, and the dust container 54 is a truncated conical container that narrows downward. Also good.

The flange portion 23 provided on the lower external surface of the dust case 20 comes into contact with the opening 51a on the upper surface of the stand upper portion 51 when the cleaner main body 2 is placed as shown in FIG. Specifically, the opening 51a is larger than the opening at the bottom of the dust case 20 (the diameter of the bottom of the dust case 20) and smaller than the diameter of the flange 23 mentioned above, so that the opening 51a and the lower part of the dust case 20 fit together. The structure is such that This is to cover the opening 51a with the lower part of the dust case 20, and also has the effect of fixing the vacuum cleaner 1 to the charging stand 5 in a state where it is placed.

Although the details of the function will be described later, the protrusion 60 on the upper surface of the stand upper part 51 allows the bottom of the dust case 20 to It is provided to open the lid 25.

The dust container 54 has vertical unevenness on its external surface, and a hole 55 is provided in the groove 54a. When the dust container 54 is attached to the stand upper part 51, by providing a hole 55 in the groove 54a on the surface of the dust container 54, the gap between the dust container 54 and the inner wall surface of the stand upper part 51 can be increased, and the air flow described later can be improved. It has a positive effect.

FIG. 5 is a perspective view of the stand upper part 51 with the dust container 54 removed. The clamp 56 provided on the dust container 54 has a protruding cylindrical convex portion 56a, and the clamp 56 can be tilted toward the inside of the dust container 54 by cutouts on the left and right sides, and the rigidity of the material allows it to remain in its original position even if it is tilted. Return to When the dust container 54 is mounted on the stand upper part 51, the protrusion 56a of the clamp 56 comes into contact with the inner wall surface of the stand upper part 51, and the clamp 56 is tilted inside the dust container 54. Then, when the dust container 54 is pushed upward, the hole 51b provided on the side surface of the stand upper part 51 fits into the convex part 56a, and the dust container 54 is fixed to the stand upper part 51.

FIG. 6 is a perspective view of the dust container 54, showing a state in which a plastic bag 70 is attached to the dust container 54. When the dust container 54 is inserted from the bottom side of the stand upper part 51 with the plastic bag 70 attached to the dust container 54, the plastic bag 70 is fixed inside the stand upper part 51.

FIG. 7 is a sectional view taken along the line AA shown in FIG. 1 when the vacuum cleaner 1 is placed on the charging stand 5 after cleaning. When the vacuum cleaner 1 is placed on the charging stand 5, the garbage disposal button 21 provided in the dust case 20 of the vacuum cleaner body 2 is pressed by the protrusion 60 provided on the upper surface of the stand upper part 51, and the bottom cover 25 opens within the stand upper part 51. . At this time, the dust discharge mechanism 22 provided in the dust case 20 pushes out the dust 80 inside the dust case 20 downward, and the dust 80 is discharged into the dust container 54, although the details of the structure are omitted. As described above, since the plastic bag 70 is attached to the dust container 54, the dust 80 is contained within the plastic bag 70. In conventional cyclone vacuum cleaners, when discharging dust from the dust case 20, for example, when discharging it into a trash can, the dust may fly up, but in the present invention, the lower part of the dust case 20 and the flange 23 are connected to the opening of the dust container 54. 51a, it is possible to suppress dust from flying up after the garbage is thrown away. In addition, the dust that flies up inside the dust container 54 and the stand upper part 51 settles over time, so that the dust will not fly up when the vacuum cleaner 1 is removed for the next cleaning. Further, when the vacuum cleaner 1 is removed, the inside of the dust container 54 can be seen through the opening 51a on the upper surface of the stand upper part 51, so that it is easy to see how much dust has accumulated.

Next, the hole 59 provided in the base portion 53 of the charging stand 5 described above for sucking out the air inside the charging stand 5 will be described (see FIGS. 2 and 3). FIG. 8 is an external perspective view showing a state in which the suction body 4 of the vacuum cleaner 1 is placed on the base portion 53 facing the charging stand 5. FIG. 9 shows a side center sectional view of the charging stand 5, and arrows shown in the figure indicate air flow. Further, FIG. 9 shows a state in which a plastic bag 70 is attached to the dust container 54.

When the mouthpiece body 4 is placed facing the charging stand 5, the movable part 4a of the mouthpiece body 4 fits into the recess 58 provided in the base part 53. The gap between the surface and the surface can be minimized. This is to increase the amount of air sucked through the holes 59 when the operating switch 11 of the cleaner main body 2 is pressed to operate the cleaner in the state shown in FIG.

As shown in FIG. 8, when the operation switch 11 of the vacuum cleaner main body 2 is pressed down with the suction body 4 placed on the base part 53 to operate, the hole 59 provided in the base part 53 opens in the direction of the arrow shown in FIG. The air inside the charging stand 5 is sucked out. Since the plastic bag 70 is attached, the air to be sucked out goes from the outside of the plastic bag 70 to the inside of the dust container 54, through the hole 55 provided in the dust container 54, and from the outside of the dust container 54 to the inside of the lower part 52 of the stand and the base. This leads to section 53. By sucking out the air outside the plastic bag 70 and inside the dust container 54, the plastic bag 70 sticks to the inner wall surface of the dust container 54, and the plastic bag 70 inside the dust container 54 is moved inside the dust container 54. It can be expanded into a conforming shape. Thereby, the plastic bag 70 does not get in the way when dust is discharged, the dust can be dropped to the bottom of the dust container 54, and the plastic bag 70 can be used effectively. In this embodiment, a hole 55 is provided in the dust container 54 and a hole 59 is provided in the base portion, but these holes are provided in order to spread the plastic bag 70 using the suction force of the vacuum cleaner 1, as described above. When attaching the plastic bag 70 to the dust container 54, it is not necessary to provide holes as long as the user pushes the plastic bag 70 apart by hand.

As described above, by providing the dust container 54 on the charging stand 5, it is possible to suppress dust from flying up when disposing of garbage. Furthermore, since the charging stand 5 also has the function of charging the vacuum cleaner main body 2, the vacuum cleaner 1 is placed on the charging stand 5 every time it is used. Therefore, since the dust inside the dust case 20 is collected every time it is cleaned (every time it is charged), it is possible to prevent dust from accumulating too much on the inner tube 30 and from getting tangled with long hair. The frequency of maintenance can be greatly reduced.

Embodiment 2 A second embodiment of the present invention will be described below with reference to FIG. FIG. 10 is a cross-sectional view taken along the line AA shown in FIG.

The charging stand 5 of the second embodiment includes an electric blower 91 and a paper pack 90 inside. As in the first embodiment, when the vacuum cleaner 1 is placed on the charging stand 5 after cleaning, the bottom cover 25 of the dust case 20 provided in the vacuum cleaner body 2 opens to discharge the sucked dust. The feature of the second embodiment is that the electric blower 90 is activated when the vacuum cleaner 1 is placed on the charging stand, and the dust 80 in the dust case 20 is forcibly collected in the paper pack 90. The charging stand 5 is composed of a stand section 50 and a base section 53, and the stand section 50 is divided into three rooms as shown in the figure.

The first room is a stand upper part 51, the second room is a dust collection case 61 to which a paper pack 90 can be attached, and the third room is a motor case 71 equipped with an electric blower 91, and each space (room) is in communication with each other. ing.

Although not shown, the stand upper part 51 is provided with a switch (such as a tact switch) for driving the electric blower 91 on the upper surface of the stand upper part 51 of the charging stand 5 . The switch is located at a position where it can be pressed by the dust case 20 or the like when the vacuum cleaner main body 2 is placed.

The upper part of the stand 51 only needs to be higher than the locus of rotation of the bottom cover 25 of the dust case 20, and the space is gradually narrowed in a conical shape toward the hole communicating with the second room (the entrance of the paper pack 90). In addition, dust is smoothly contained within the paper pack 90.

The dust collection case 61 is a room in which the paper pack 90 is attached, as described above. The inside of the dust collection case 61 includes a fixing part (not shown) for fixing the entrance of the paper pack 90 on the top surface, and a plurality of holes communicating with the third chamber on the bottom surface. The holes on the bottom surface may be in a grid shape, mesh, etc. as long as the paper pack 90 does not fall, and it is desirable that the opening area be as large as possible.

Further, the side surface of the dust collection case 61 is provided with a lid (not shown) for attaching and detaching the paper pack 90. It is desirable that the lid has a structure that can be opened and closed by being fixed with a hinge or the like, that it is kept airtight with packing or the like when closed, and that it has a locking mechanism. Generally, since the charging stand 5 is often installed near a wall, the lid is provided on the side of the charging stand 5, but the lid is not limited to this, and may be provided on the back.

The motor case 71 communicates with the lower surface of the dust collection case 61, and internally supports and fixes the electric blower 91 against vibration. In this embodiment, a bellmouth-shaped flow path is provided from the bottom surface of the dust collection case 61 to the inlet of the electric blower 91, but the distance between the electric blower 91 and the dust collection case 61 may be shortened by lifting the electric blower 91. In this embodiment, considering ease of use, the dust collection case 61 is provided above so that the user does not have to bend down when attaching/detaching the paper pack 90. The height may be reduced.

The motor case 71 communicates with the base portion 53, and the base portion 53 includes a drive circuit board 93 for the electric blower 91 and an exhaust hole 92. The exhaust hole 92 may be provided in the motor case 71 as long as it is on the exhaust side of the electric blower 91.

When the vacuum cleaner 1 is placed on the charging stand 5 having such a structure, the switch on the upper part of the stand 31 is pressed down almost at the same time as the bottom cover 25 of the dust case 20 of the vacuum cleaner body 2 is opened, and the electric blower 91 is driven. . The suction force of the electric blower 91 sucks outside air from the suction body 4 and the exhaust port (not shown) of the cleaner body 2. Air taken in from the mouthpiece body 4 passes through the extension pipe 3, inside the dust case 20, and reaches the paper pack 90. Air taken in from the exhaust port of the cleaner body 2 reaches the paper pack 90 through the exhaust port, an electric blower (not shown), a filter (not shown), and the inside of the inner cylinder 30. Therefore, not only the dust 80 but also dust and the like attached to the inner wall of the dust case 20 due to static electricity etc. are forcibly accommodated in the paper pack 90. At this time, it is desirable that the driving of the electric blower 91 is automatically stopped after a predetermined period of time has elapsed.

As in this embodiment, by forcibly sucking up the dust inside the dust case 20 with the electric blower 91, it is possible to efficiently suck up the dust that flies up when trash is thrown away, and also to remove the dust that has adhered to the inner wall surface of the dust case 20 due to static electricity, etc. Since the dust can also be collected, the inside of the dust case 20 can be kept clean. Furthermore, since the charging stand 5 also has the function of charging the vacuum cleaner main body 2, the vacuum cleaner 1 is placed on the charging stand 5 every time it is used. Therefore, since the dust inside the dust case 20 is collected every time it is cleaned (every time it is charged), it is possible to prevent dust from accumulating too much on the inner tube 30 and from getting tangled with long hair. The frequency of maintenance can be greatly reduced.
