Description

  The present invention relates to a vacuum cleaner including a dust collecting container in which dust is accumulated.

  Conventional vacuum cleaners are generally connected to a vacuum cleaner main body in which an electric blower is housed, a dust collection hose communicated with the vacuum cleaner main body, a hand operation tube communicated with the dust collection hose, and a hand operation tube. An extension pipe and a suction port connected to the extension pipe are provided. A suction opening facing the surface to be cleaned is formed in the suction port body.

  When a conventional vacuum cleaner is operated, a negative pressure is generated in the main body of the vacuum cleaner by the operation of the electric blower. This negative pressure acts on the suction port body through the dust collecting hose, the hand control pipe, and the extension pipe. Then, the vacuum cleaner sucks the dust collected on the surface to be cleaned such as the floor from the suction opening of the suction port body together with the air to clean the surface to be cleaned. The dust-containing air sucked into the suction port body is separated into air and dust by a high-speed separation method housed in the cleaner body or dust separation means such as a filter. The dust separated from the dust-containing air is guided and accumulated in a dust collection container that is detachably provided on the cleaner body.

  Here, the dust collection container cannot accumulate dust exceeding a predetermined amount, and it is necessary to periodically discard the accumulated dust. At this time, it is desirable that the dust collecting container can be easily discarded without touching the dust by the user of the vacuum cleaner.

  Therefore, the electric vacuum cleaner described in Patent Document 1 includes a dust collection container having a lid that can be opened by operating a button provided on a handle. In this dust container, the lid is opened and the dust is discarded by removing it from the cleaner body and operating the handle button.

Moreover, the vacuum cleaner of patent document 2 is provided with the dust collecting container which has a cover body which can be opened in a double-opening shape by operation of the button provided in the handle.

The portion 20 is pivotally supported so as to be rotatable around the rotation axis H1.

  In addition, the rotational speed of the opening-and-closing lid part 17 can be suppressed by providing the hinge part 20 with a damper or an elastic member that urges the opening-and-closing lid part 17 in the closing direction.

  5 and 6 are partial cross-sectional views of the dust separating and collecting unit accommodated in the vacuum cleaner body of the electric vacuum cleaner according to the present invention. FIG. 5 is a cross-sectional view showing a state where the open / close lid portion of the dust separation dust collection unit is closed, and FIG. 6 is a cross-sectional view showing a state where the open / close lid portion of the dust separation dust collection unit is opened. .

  As shown in FIG. 5, the opening / closing lid portion 17 is provided with a sealing member 45 that seals the opening 25 of the dust collection portion 16. The opening 25 of the dust collecting portion 16 is closed by the opening / closing lid portion 17 to form a space for storing dust. The inner surface portion 46 of the opening / closing lid portion 17 is formed to be curved in a concave shape.

  The guide plate body 24 is located inside the space where dust is accumulated, rather than the opening / closing lid portion 17. When the opening 25 of the dust collecting unit 16 is closed by the opening / closing lid 17, the guide plate 24 and the opening / closing lid 17 overlap each other. The dust guided to the dust collection unit 16 is accumulated on the upper surface portion 47 of the guide plate body 24.

  The hinge portion 20 that pivotally supports the opening / closing lid portion 17 and the stopper portion 26 that holds the closed opening / closing lid portion 17 are provided to face each other with the dust collection portion 16 interposed therebetween. The guide plate 24 is pivotally supported by an inner lid hinge portion 48 provided in the dust collection portion 16 so as to be rotatable. The inner lid hinge portion 48 is provided on the side of the dust collecting portion 16 on the side where the stopper portion 26 of the opening / closing lid portion 17 exists.

  The total length L1 from the end of the part where the rotation axis H1 of the opening / closing lid 17 is provided to the end of the part where the stopper 26 is provided, and the end of the part where the rotation axis H2 of the guide plate 24 is provided When comparing the total length L2 from the first end to the other end, the total length L1 is longer.

  As shown in FIG. 6, when the lid locking mechanism 18 is released, the opening / closing lid 17 rotates about the rotation axis H 1, and the guide plate 24 rotates about the rotation axis H 2 of the inner lid hinge 48. The opening / closing lid portion 17 and the guide plate body 24 are each opened.

  The rotation resistance of the rotation axis H1 of the hinge part 20 is larger than the rotation resistance of the rotation axis H2 of the inner lid hinge part 48, and the opening / closing lid part 17 does not open before the guide plate body 24.

  Here, the opening operation of the opening / closing lid portion 17 and the guide plate body 24 of the dust collecting portion 16 will be described in more detail.

  FIG. 7 is a partial cross-sectional view showing a state in the middle of opening of the opening / closing lid portion of the dust separation and dust collection unit housed in the vacuum cleaner main body of the electric vacuum cleaner according to the present invention.

  As shown in FIG. 7, when the opening / closing lid portion 17 of the dust collecting portion 16 starts to rotate about the rotation axis H <b> 1, the tip 49 of the guide plate body 24 slides on the inner surface portion 46 of the opening / closing lid portion 17. However, it starts to rotate around the rotation axis H2 of the inner lid hinge portion 48. At this time, the direction of rotation of the guide plate 24 is opposite to the direction of rotation of the opening / closing lid 17.

  As a result, the dust accumulated in the dust collecting portion 16, that is, the dust accumulated in the upper surface portion 47 of the guide plate body 24, passes along the upper surface portion 47 and the front end of the inner surface portion 46 of the open / close lid portion 17 and the guide plate body 24. Gradually gathered toward the contact portion with the portion 49.

  When the opening / closing lid portion 17 and the guide plate body 24 are further rotated, the contact portion between the inner surface portion 46 of the opening / closing lid portion 17 and the tip portion 49 of the guide plate body 24 moves away from the opening 25 of the dust collecting portion 16. . At this time, the dust collected in the contact portion between the inner surface portion 46 of the opening / closing lid portion 17 and the distal end portion 49 of the guide plate body 24 is also gathered from the opening 25 of the dust collection portion 16 into the dust collection portion 16. Move away to the outside.

  Eventually, when the opening / closing lid 17 and the guide plate 24 rotate at a predetermined rotation angle from the entire length L1 of the opening / closing lid 17 and the entire length L2 of the guide plate 24, the inner surface 46 and the guide of the opening / closing lid 17 are guided. The opening 25 is opened away from the tip 49 of the plate 24 as shown in FIG. If it does so, the dust which became a lump in the space between the opening-and-closing lid part 17 and the guide plate body 24 will begin to fall freely.

  At this time, since the total length L2 of the guide plate body 24 is smaller than the total length L1 of the opening / closing lid portion 17, the guide plate body 24 starts to rotate while the rotation angle of the opening / closing lid portion 17 is small. The body 24 does not open vigorously.

  Further, since the inner surface portion 46 of the opening / closing lid portion 17 is formed in a concave shape, the guide plate body 24 starts to rotate while the rotation angle of the opening / closing lid portion 17 is small. However, there will be no momentum.

  FIG. 8 is a cross-sectional view of another example showing a state in which the opening / closing lid portion of the dust separation and dust collection unit housed in the vacuum cleaner main body of the electric vacuum cleaner according to the present invention is opened.

  As shown in FIG. 8, a rotation suppression convex portion 50 is formed on the inner lid hinge portion 48 of the guide plate body 24 provided in the dust collection portion 16.

  When the rotation angle θ1 of the guide plate body 24 is reached, the rotation suppression convex portion 50 is pressed against the inner wall of the dust collecting portion 16. The guide plate body 24 does not rotate more than the rotation angle θ1. Here, the rotation angle θ1 of the guide plate body 24 is such that when the guide plate body 24 and the opening / closing lid portion 17 are in contact with each other, the guide plate body 24 and the opening / closing lid portion 17 are in contact with each other. The angle θ2 formed with the opening / closing lid portion 17 is determined to be an obtuse angle.

  According to the guide plate body 24 according to the present embodiment, when the open / close lid portion 17 is closed after the dust is discarded from the dust collecting portion 16, only the operation of closing the open / close lid portion 17 is performed. 24 can be closed together.

  According to the vacuum cleaner 1 according to the present embodiment, when the dust accumulated in the dust collecting portion 16 is discarded, the dust is collected almost in a lump by the opening / closing lid portion 17 and the guide plate body 24, and the dust collecting is performed. It is separated from the opening 25 of the part 16 while being guided to the outside of the dust collecting part 16 and starts to fall freely. When the dust starts to fall freely, a part of the periphery of the dust is partitioned by the opening / closing lid portion 17 and the guide plate body 24. Therefore, when the dust accumulated in the dust collection unit 16 is discarded, the dust does not scatter around the dust collection unit 16.

  In addition, when the dust is discarded, the falling position of the dust can be easily predicted, so that the dust can be reliably discarded in a place intended by the user, for example, a trash can.

  Furthermore, since the dust collection part 16 becomes a box-shaped body closed by the opening / closing lid part 17, and the space where dust is accumulated is partitioned, the dust collection part 16 and the opening / closing lid part 17 that is the lid body are separated. A structure for sealing the dividing surface can be easily configured.

  After the dust is discarded, the guide plate member 24 can be closed together only by the operation of closing the opening / closing lid portion 17, so that the user can easily close the dust collecting portion 16. And from the viewpoint of hygiene.

  The vacuum cleaner according to the present invention is not limited to the canister type vacuum cleaner 1 but may be an upright type, a stick type, or a handy type vacuum cleaner.
