The front side, rear side, left side, and right side described with reference to FIGS. 1 and 2 do not necessarily match the front side, rear side, left side, and right side described with reference to FIGS. This is because they are shown in each drawing for ease of explanation.

FIG. 3 is a perspective view of the dust collector 3. FIG. The left side of the dust collector 3 shown in FIG. The front side, the upper side of the paper, is the upper side of the dust collector 3, and the lower side of the paper is the lower side of the dust collector 3.

The dust collecting device 3 includes a dust collecting container 6 made of a transparent or translucent material (for example, a resin such as polyethylene terephthalate) for collecting dust centrifugally separated from the sucked air, and a dust collecting container 6 which is detachable from the dust collecting container 6 . and a releasably connected lid 7 . A suction port 8 is formed at the rear of the dust collection container 6 for receiving the suction air (arrow in FIG. 3) sucked through the nozzle 5 and the extension pipe 4 . Furthermore, the lid portion 7 is formed with an outlet 9 for discharging the suctioned air from which the dust is separated by centrifugal separation to the main body 1 of the cleaner. A filter 10 is provided for removing small dust particles. As the filter 10, for example, a pleated filter or the like is used.

The lid portion 7 is attached to the dust collecting container 6 by a first engaging portion 11 arranged in front of the dust collecting device 3 and a second engaging portion 12 arranged in the rear side of the dust collecting device 3. Removably engaged. The first engaging portion 11 is, for example, disengaged from the dust collection container 6 when a user slides up and down, and the second engaging portion 12 is, for example, The engagement with the dust collection container 6 is released by a person's pressing operation. Also, the lid portion 7 is detachably engaged with the dust collection container 6 via a packing or the like (not shown).

FIG. 4 is a perspective view showing a state in which the lid portion 7 and the inner cylinder 13 are removed from the dust collection container 6. As shown in FIG. 4, the left side of the dust collector 3 is the left side of the dust collector 3, the right side of the paper is the right side of the dust collector 3, the front side of the paper is the rear side of the dust collector 3, and the back side of the paper is the back side of the paper. The front side of the dust collector 3 , the upper side of the paper surface is the upper side of the dust collector 3 , and the lower side of the paper surface is the lower side of the dust collector 3 .

As shown in FIG. 4 , an inner cylinder 13 is attached to the lid portion 7 , and the inner cylinder 13 has a central portion 15 having a plurality of opening holes 14 and an umbrella portion 16 below the central portion 15 . are doing. A tubular lower cylinder 17 is formed downwardly projecting from the central portion of the umbrella portion 16 . A mesh filter is arranged in the opening 14 of the central portion 15, and dust in the sucked air is removed by this filter.

The head portion 16 has a horizontal protrusion 18 that protrudes in the horizontal direction, and a lower protrusion 19 that protrudes downward from the protrusion. The horizontal projection 18 projects horizontally more or less than the position where the lower projection 19 exists. This protruding portion contributes to some extent to preventing the dust collected in the dust container 6 from flying up.

A step portion 20 having a substantially stepped notch is formed behind the umbrella portion 16, and a notch portion 21 having a substantially V-shaped notch is formed on the left side of the umbrella portion 16. . Further, the cutout portion 21 is formed with a substantially V-shaped rising prevention rib 22 projecting in the horizontal direction from the cutout portion 21 . This rising prevention rib 22 is for preventing the dust collected in the vicinity of the lower portion of the rising prevention rib 22 of the dust collecting container 6 from rising up.

The notch 21 is formed in the lower protrusion 19 for the purpose of collecting as much dust as possible inside the dust collecting container 6 and facilitating the passage of suction air.

The suction air sucked from the suction port 8 has a particularly high wind velocity immediately after entering the dust collection container 6. - 特許庁Therefore, there is a possibility that dust collected near the suction port 8 may rise. In order to avoid such a situation as much as possible, in the present embodiment, a rising prevention rib 22 is provided in the vicinity of the suction port 8 . More specifically, the rising prevention rib 22 is formed on the surface side of the inner cylinder 13 (more specifically, the lower protrusion 19 of the inner cylinder 13) through which the suction air immediately after being sucked from the suction port 8 passes. is set in

In addition, the rising-up prevention rib 22 has a horizontally extending portion (horizontal portion 30) and downwardly inclined portions (inclined portions 31) on both left and right sides of this surface. It has a V-shaped shape (see FIG. 7). The horizontal portion 30 is substantially parallel to the direction of the suction air coming in from the suction port 8, and this shape prevents the wind speed of the suction air from decreasing as much as possible. In addition, the inclined portion 31 is inclined so as to avoid a reduction in the wind speed of the suction air rotating inside the dust container 6 as much as possible.

It is necessary that the ribs 22 for preventing dust from rising up have a shape that can reduce the rising of dust as much as possible. In the embodiment, by adopting a substantially V-shaped shape having the inclined portion 31, the flow of air is not hindered as much as possible, and the rise of dust is prevented as much as possible.

FIG. 5 is a perspective view showing a state in which the lid portion 7 and the inner cylinder 13 are removed from the dust collection container 6. As shown in FIG. 5, the left side of the dust collection container 6 is the left side of the dust collection container 6, the right side of the paper is the right side of the dust collection container 6, the front side of the paper is the rear side of the dust collection container 6, and the back side of the paper is the back side of the paper surface. The front side of the dust collection container 6, the upper side of the paper surface is the upper side of the dust collection container 6, and the lower side of the paper surface is the lower side of the dust collection container 6. Although a suction port 8 is actually formed in the dust collection container 6, the illustration of the suction port 8 is omitted.

A first collision wall 23 projecting from the inner surface of the lower protrusion 19 toward the central axis of the inner cylinder 13 is formed at the rear portion of the umbrella portion 16 in FIG. The impingement wall 23 is indicated by a dotted line). When the suction air hits the first collision wall 23 , dust contained in the airflow falls to the bottom of the dust collection container 6 .

On the other hand, a second collision wall 24 projecting toward the central axis of the dust collection container 6 is formed on the inner surface of the rear portion of the dust collection container 6 (in FIG. 6, the second collision wall 24 are shown as solid lines). When the suction air hits the second collision wall 24 , the dust contained in the airflow falls to the bottom of the dust collection container 6 .

It is preferable to form one first collision wall 23 and one second collision wall 24 at the positions shown in FIG. This is because if the number of collision walls is too large, the wind speed of the suction air may decrease.

6 is a perspective view showing a state in which the lid portion 7 shown in FIG. 5 is attached to the dust container 6. FIG. Incidentally, the suction port 8 is actually formed in the dust collection container 6, but if the suction port 8 is shown in FIG. Illustration is omitted. However, the position of the suction port 8 in FIG. 6 can be easily understood from FIG. 3 and the like.

In FIG. 6, as in FIG. 5, the left side of the dust collection container 6 on the paper surface is the left side of the dust collection container 6, the right side of the paper surface is the right side of the dust collection container 6, the front side of the paper surface is the rear side of the dust collection container 6, and the back side of the paper surface is the rear side of the dust collection container 6. The front side of the dust collection container 6, the upper side of the paper surface is the upper side of the dust collection container 6, and the lower side of the paper surface is the lower side of the dust collection container 6.

In FIG. 6 , arrows and solid lines overlapping the arrows indicate the flow of the suction air in the dust collection container 6 . The suctioned air entering the dust container 6 from the suction port 8 begins to rotate clockwise inside the dust container 6, and rotates clockwise around the inner cylinder 13, that is, in the direction indicated by the arrow in FIG. do.

As the suction air rotates clockwise around the inner cylinder 13 many times, the suction air gradually moves toward the bottom surface of the dust container 6 . The suctioned air hits the right side of the second collision wall 24 , and dust contained in the suctioned air accumulates on the right side of the second collision wall 24 due to the impact.

Although not shown in FIG. 6, the suction air rotates clockwise also inside the lower protrusion 19, and the suction air hits the first collision wall 23, causing the dust to move toward the first collision wall 23. falls on the bottom surface of the dust collection container 6 and accumulates on the right side of the second collision wall 24.例文帳に追加

In this way, dust accumulates in the dust collection container 6 in order from the right side of the second collision wall 24 counterclockwise. When the dust accumulates up to the left side of the second collision wall 24 and reaches the upper end of the dust disposal line 25 printed on the dust collection container 6, the user removes the dust collection device 3 from the main body 1 and engages the first engagement. By disengaging the portion 11 and the second engaging portion 12 from the dust collection container 6 and removing the lid portion 7 from the dust collection container 6, the dust in the dust collection container 6 is thrown into the trash can. Dust disposal is complete.

When the dust is collected up to the upper end of the dust disposal line 25, the height of the dust on the left side of the dust collection container 6 and the height of the dust on the right side of the dust collection container 6 in FIG. 6 are substantially the same. If the dust piles up any further, the height of the dust becomes higher than the notch 21, and not only is there a possibility that the dust will rise up, but it will also become difficult for the suction air to rotate within the dust collecting container 6.例文帳に追加Therefore, it is preferable that the garbage disposal line 25 is printed up to the approximately V-shaped inclined surface (inclined portion 31) of the notch portion 21. As shown in FIG.

Further, if the second collision wall 24 were not provided, there is a possibility that dust would accumulate on the bottom of the dust collection container 6 from the left side of the dust collection container 6 . As a result, even though the dust does not accumulate on the entire bottom of the dust collection container 6, the dust accumulates near the upper end of the dust disposal line 25 printed on the left side of the dust collection container 6, and the user cannot collect the dust. It is also possible that the dust inside the container 6 is thrown into a trash can.

In this embodiment, in order to avoid such a situation as much as possible, as described above, dust accumulates in order from the right side of the dust collection container 6, and when the dust accumulates up to the dust disposal line 25 of the dust collection container 6, , the dust up to the dust disposal line 25 is in a state in which the entire dust collection container 6 is collected substantially evenly.

When the user sees that the dust has accumulated up to the dust disposal line 25 and goes to throw the dust into the trash can, the dust is accumulated almost evenly throughout the dust collection container 6, so the user does not want to throw the dust into the trash can. The number of throw-aways can be minimized.

FIG. 7 is a perspective view showing a state in which the dust container 6 is filled with dust. 7, the left side of the dust collection container 6 is the left side of the dust collection container 6, the right side of the paper is the right side of the dust collection container 6, the front side of the paper is the rear side of the dust collection container 6, and the back side of the paper is the back side of the paper surface.

Although a suction port 8 is actually formed in the dust collection container 6, the illustration of the suction port 8 is omitted. However, the position of the suction port 8 in FIG. 7 can be easily understood from FIG. 3 and the like.

As described earlier with reference to FIG. 6, dust accumulates on the right side of the second collision wall 24, and this dust accumulates in the dust collection container 6 in order counterclockwise.

A first gap 26 is formed between the first collision wall 23 and the second collision wall 24 . This first gap 26 is a gap for allowing the suction air to pass from the right side of the second collision wall 24 to the left side. It may become impossible to centrifuge the dust efficiently.

A stepped portion 20 is formed on the bottom side of the lower projection 19 . The height width of the step portion 20 is substantially the same as that of the first gap 26 . Even if dust accumulates in the dust collection container 6 and the height of the stepped portion 20 reaches approximately the height of the second collision wall 24, the suction air is blown through the gap between the stepped portion 20 and the first gap 26. It's meant to let you pass through.

When the dust collecting container 6 of FIG. 7 is viewed from the rear of the dust collecting container 6, the suction port 8, the horizontal portion 30 and the inclined portion 31 of the rising prevention rib 22, and the first An impingement wall 23 and a second impingement wall 24 are arranged. With such a positional relationship, the dust is accumulated in the dust collection container 6 counterclockwise in order from the right side of the first collision wall 23 and the second collision wall 24 , and the dust is evenly distributed on the bottom of the dust collection container 6 . In addition, it is possible to prevent the dust from rising up due to the high-velocity suction air coming from the suction port 8 as much as possible.

As shown in FIG. 8 , the first collision wall 23 and the second collision wall 24 exist at substantially the same position in the vertical direction of the dust collector 3 . Also, the suction air passes through the first gap 26 to the fourth gap 29 shown in FIG. 8, and passes from the right side to the left side of the first collision wall 23 and the second collision wall 24 in FIG.

8, the first gap 26 is the gap between the first collision wall 23 and the second collision wall 24, and the second gap 27 is the gap between the lower cylinder 17 and the first collision wall 23. A third gap 28 is a gap between the first collision wall 23 and the inside of the dust collection container 6, and a fourth gap 29 is a gap between the lower cylinder 17 and the third 2 and the collision wall 24 . These gaps are gaps for allowing the suction air to swirl inside the dust collecting container 6 as much as possible when dust accumulates inside the dust collecting container 6 .
