Due to the intake force when the electric blower is driven, dust-containing air is sucked from the suction port 201, and the sucked dust-containing air is sucked into the cleaner body 204 through the extension pipe 202 and the hose 203, and a dust collecting case 301 described later. After collecting (collecting) the dust, exhaust the air out of the machine.

  FIG. 3 is an external view of the cleaner body 204 according to one embodiment of the present invention. As shown in FIG. 3, the vacuum cleaner main body 204 has a dust collection portion 205 that forms a dust collection portion 205 in a dust collection case storage portion formed in a recess of the upper body case 207 disposed between the lower body case 206 and the upper lid 302. A case 301 is detachably attached, and an upper lid 302 that can be freely opened and closed is provided so as to cover the dust collecting portion 205. The upper lid 302 is attached to the upper rear portion of the upper body case 207 so as to be able to turn. As shown in FIG. 3, the dust collection case 301 is taken in and out by opening the upper lid 302, and the upper lid 302 is closed during operation of the vacuum cleaner.

  When the cleaner is operated, the dust-containing air conveyed to the cleaner main body 204 is separated into dust and air by the dust collecting unit 205, and the separated dust is stored in the dust collecting case 301.

  FIG. 1 is an external view of a dust collection case 301 according to an embodiment of the present invention. The dust collection case is provided with a first locking means 102 and a second locking means 104. The first locking means 102 also serves as a lid opening / closing button for opening and closing the dust discharge lid 101, and the second locking means 104 functions as an erroneous opening / closing prevention function of the first locking means 102.

  FIG. 11 is a side view of the second locking means 104 according to one embodiment of the present invention. The second locking means 104 includes a convex portion 401 that is pushed from the upper main body case when the dust collecting case 301 is attached to the cleaner main body 204, that is, a power point. When the convex portion 401 is pushed, the shaft 403 rotates around the rotation center. The hook 402 is provided on the upper part of the second locking means 104 on the opposite side of the shaft 403 across the convex portion 401. A spring B405 is provided between the second locking means 104 and the dust discharge lid 101. For this reason, when the convex portion 401 is not biased, the hook 402 is pushed by the spring B and biased to the left of the arrow in FIG. 11, that is, in a direction away from the dust discharge lid 101.

  Here, the second locking means 104 is provided with a collar C411. The cage C411 is engaged with the dust discharge lid 101, and the shaft 403 is attached to the dust discharge lid 101, so that the second locking means 104 is prevented from being detached from the dust discharge lid 101.

  Note that when the convex portion 401 is pushed, the second locking means 104 may move in parallel to the dust discharge lid 101 side. However, when the convex portion 401 is pushed, the shaft 403 rotates as shown in FIG. It is more preferable to rotate about the center because the displacement of the hook 402 can be increased compared to the displacement of the convex portion 401 and the first locking means 102 can be easily locked.

FIG. 12 is a side view of the first locking means 102 according to one embodiment of the present invention. Since the first locking means 102 is biased by the spring A404, the flange A409 arranged on the opposite side of the spring A404 across the shaft 107 provided on the first locking means 102 is shown in FIG. The arrow is biased downward. For this reason, the jar A409 engages with a locking portion 106 provided on the dust discharge lid 101 to close the dust discharge lid 101. In addition, since the handle 103 presses the upper side of the first locking means 102, it is prevented from being detached from the dust collecting case 301.

Next, the function of the second locking means 104 will be described with reference to FIGS. FIG. 4 is an external view of a dust collection case 301 according to an embodiment of the present invention. FIG. 7 is a central longitudinal sectional view of the dust collecting case 301 shown in FIG. FIG. 8 is an enlarged view of part A shown in FIG.

  The dust collecting case 301 is provided with a dust discharge lid 101 for discarding accumulated dust and a first locking means 102 that also serves as a lid opening / closing button for opening and closing the dust discharge lid 101. When the dust collecting case 301 is taken out from the dust collecting unit 205, the user holds the handle 103 and pulls it out from the cleaner main body 204. At this time, there is a possibility that the first locking means 102 may be pushed by mistake. Therefore, in this invention, the 2nd latching means 104 is provided in the outer side of the dust discharge lid 101 so that rotation is possible. That is, when the first locking means 102 is operated when the second locking means 104 is in a position where the second locking means 104 is locked with the first locking means 102, the first locking means 102 is moved to the dust discharge lid. Although the locking of 101 is released, the dust discharging lid 101 is not opened because it is locked with the second locking means 104.

  In these drawings, the dust collecting case 301 is attached to the cleaner main body 204, and the second locking means 104 is shown in FIG. It is in a state. In the state where the dust collecting case 301 is attached to the cleaner body 204, the second locking means 104 has the convex portion 401 at the tip abutting against the upper body case 207 of the cleaner body 204, and the dust collecting case 301. It is pushed toward the filter 303 provided on the downstream side.

In the present embodiment, when the convex portion 401 is pushed, the second locking means 104 is disposed in the second locking means 104 with the shaft 403 provided below the convex portion 401 as the rotation center. The hook 402 is biased toward the dust discharge lid 101 side. At this time, even if the first locking means 102 is pushed down, the dust discharge lid 101 can be prevented from opening because it is locked by the hook 402. In addition, if the protruding hooks B410 are provided in the first locking means 102, the hook 402 can be made difficult to come off from the first locking means.

Here, the second locking means 104 has a hook 402 disposed above the second locking means 104 with the shaft 403 provided below the convex portion 401 as a rotation center on the dust discharge lid 101 side. It is energized. Since it arrange | positions in this way, compared with the displacement of the convex part 401, the displacement of the hook 402 can be enlarged. For this reason, the action | operation which the 2nd latching means 104 latches the said 1st latching means 102, and cancellation | release of this latching can be performed reliably.

As described above, even if the user accidentally presses the first locking means 102, the dust discharging lid 101 does not open because it is locked by the second locking means 104. Further, even if the dust collecting case 301 is pulled out while the first locking means 102 is pressed, the dust discharge lid 101 will not be opened because it is continuously locked by the second locking means 104. As a result, when the dust collection case 301 is taken out from the cleaner main body 204, the dust discharge lid 101 can be prevented from being accidentally opened, and dust stored in the dust collection case 301 can be prevented from being spilled.

  Here, when the dust collecting case 301 is attached to the cleaner body 204, the first locking means 102 may not be pushed by the second locking means 104. Further, even if the first locking means 102 can be pushed when the dust collecting case 301 is attached to the cleaner body 204, the hook 402 and the first locking means provided on the second locking means 104 If it arrange | positions so that 鉤 B410 provided in may not remove | deviate, it can prevent that the dust discharge lid | cover 101 opens accidentally.

  The first locking means 102 is provided with a flange A409 that locks the dust discharge lid 101 on the side opposite to the flange B410. The first locking means 102 is biased by a spring A404 in a direction in which the ridge A409 locks the dust discharge lid 101. For this reason, if the 1st latching means 102 is pushed down, heel A409 will move upwards, the latching of the dust discharge lid 101 will be cancelled | released, and the dust discharge lid 101 will open. Here, even when the dust discharge lid 101 is closed, the second locking means 104 is pressed in the direction opposite to the first locking means 102 by the spring B405, so that the dust discharge lid 101 is locked. There is no hindrance.

FIG. 5 is an external view of a dust collection case 301 according to an embodiment of the present invention. FIG. 9 is a central longitudinal sectional view of the dust collecting case 301 shown in FIG. FIG. 10 is an enlarged view of a portion B shown in FIG. FIG. 6 is an external view of a dust collection case according to an embodiment of the present invention. In these drawings, the dust collecting case 301 is removed from the cleaner body 204. When the dust collecting case 301 is taken out from the cleaner body 204, the convex portion 401 provided on the second locking means 104 is not biased toward the dust discharge lid 101 side. For this reason, the spring B405 (see FIG. 7) provided inside the second locking means 104 extends, rotates around the shaft 403, and moves away from the first locking means 102. As a result, the first locking means 102 can freely rotate. Further, since the rotation of the second locking means 104 is automatically performed by the spring B405, the user can use the second locking means 104.
There is no need to move.

  For this reason, when discarding the dust in the dust collecting case 301, as shown in FIG. 6, the first locking means 102 that also serves as a lid opening / closing button for opening and closing the dust discharge lid 101 may be pushed. Here, when the locking of the dust discharge lid 101 is released by pressing the first locking means 102, the dust discharge lid 101 opens and the dust can be discarded from the opening 304. For this reason, it is possible to prepare for disposal of the dust in the dust collecting case 301.
