  However, in the above configuration, the one having the above-mentioned mouth frame presser requires two operations of inserting the mouth frame after rotating the mouth frame presser in order to attach and detach the dust bag. The bag was not removable.

  In addition, when the mouth frame retainer is located at the upper part of the mouth frame, the mouth frame retainer becomes an obstacle when the dust bag is inserted, and the positioning rib that determines the position of the dust bag from above and the intake port Since it is hidden by the mouth frame presser and difficult to see, the user wears a dust bag according to his senses. For this reason, erroneous insertion has occurred, the air intake hole and the air intake port are displaced, which causes dust leakage, which causes the failure of the electric blower and the vacuum cleaner. In addition, when taking out the dust bag, which is full of dust, the mouth frame retainer gets caught in the air intake hole, making it difficult to remove, and the dust in the dust bag may spill out, which is untrustworthy to the user. The dust that spilled into the dust collection chamber entered the electric blower directly, thereby leading to the breakdown of the vacuum cleaner.

It is possible to prevent the lid from closing due to negative pressure.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
A first embodiment of the present invention will be described with reference to FIGS.

  In FIGS. 1, 2, and 3, a vacuum cleaner main body 1 includes a dust collection chamber 3 having an intake port 2 at the front and an electric blower chamber (not shown) having an electric blower 17 (shown in FIGS. 11 and 12) at the rear. The suction port 2 is provided with a vacuum cleaner main body 1 and an air tight packing A4 for a hose (not shown). The upper part of the dust collecting chamber 3 is in an open state, and has a packing B5 around the entire upper end of the open part. Reference numeral 6 denotes a lid provided on the vacuum cleaner main body so as to be rotatable about its rear portion as a fulcrum, and covers the upper opening of the dust collecting chamber 3. The lid body 6 has a tight rib 7 that is substantially in the same shape as the packing B5 and is in tight contact with the packing B5 when the lid is closed. A dust collection bag 9 having a mouth frame 8 is detachably mounted in the dust collection chamber 3. The dust bag 9 is inserted into a positioning portion 10 made of ribs and the like located on the left and right sides of the suction port 3 of the dust collection chamber 3 while the suction hole 8 a of the mouth frame 8 is opposed to the suction port 2 of the dust collection chamber 3. The lower end of the mouth frame is fitted and attached to an auxiliary positioning portion 11 such as a rib that determines the front and rear position of the mouth frame on the bottom surface of the dust collecting chamber, and the mouth frame 8 is formed by the positioning portion 10 and the auxiliary positioning portion 11. Is positioned. Note that the upper part between the left and right positioning parts 10 is not open and has an open state as described in the conventional example.

  Reference numeral 12 denotes a dust bag detecting body provided on the front inner surface of the lid body 6 and is rotatably mounted using ribs provided on the inner surface of the lid body as shown in FIGS. The dust bag detection body 12 has a detection portion 12B on the rear and a projection 12A on the front centering on the rotation support portion, both of which are integrally formed in this embodiment. The dust bag detecting body 12 constitutes the protrusion 12A at a position where the lid 6 is not closed, and the detector is located at a position where the lid 6 is brought into contact with the mouth frame 8 as the lid 6 is closed. 12B is provided. In addition, the dust bag detecting body 12 is always urged by a spring body (elastic body) 13 so that the protruding portion 12A protrudes outside the tight rib 7 at a position that prevents the lid body 6 from being closed. It is provided. The dust bag detecting body 12 is a portion of the detecting portion 12B that contacts the mouth frame 8, and engages with the mouth frame 8 when the protruding portion 12A protrudes out of the tight rib 7. A portion 12C is provided, and by this engagement, the mouth frame 8 is urged toward the intake port 2 side of the dust collecting chamber 3 by the urging force of the spring body 13 to be brought into close contact therewith.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  As shown in FIG. 4, when the lid 6 is in an open state, the dust bag detecting body 12 is urged by the spring body 13 to a position where the protruding portion 12 </ b> A protrudes outside the tight rib 7.

  In order to set the dust collection bag 9 in the dust collection chamber 3 in this state, the mouth frame 8 may be fitted to the positioning portion 10 as it is without any operation. In this state, that is, in a state where the mouth frame 8 is set at a predetermined position in the dust collection chamber 3 and the dust bag is inserted, the lid body 6 is rotated so as to be in a closed state. The detection part 12B of the dust bag detection body 12 contacts the upper end part of the mouth frame 8 as shown in FIG. When further rotated to the closed state, as shown in FIG. 5B, the detecting portion 12B starts to rotate upward, and at the same time, the protruding portion 12A rotates to move away from the tight rib 7. Finally, as shown in FIG. 3, the lid body 6 is rotated to a predetermined position to be in a closed state, and the tight rib 7 and the packing B5 are brought into contact with each other to perform air tight. Then, the mouth frame 8 is brought into close contact with the air inlet 2.

  Next, as shown in FIG. 6, when the mouth frame 8 is not inserted into the dust collection chamber 3, the protrusion 12 </ b> A of the dust collection bag detection body 12 remains in the tight rib 7 even if the lid body 6 is turned to the closed state. Therefore, the protrusion 12A is sandwiched between the tight rib 7 and the packing B5, and the lid 6 is not completely closed.

  Further, when removing the dust bag 9 from the dust chamber 3, it is only necessary to open the lid 6, whereby the dust bag detector 12 is rotated by the urging force of the spring body 13, and the projection 12 </ b> A thereof is tight rib 7. And the engaging portion 12C of the detecting portion 12B is disengaged from the mouth frame 8. Therefore, it is sufficient to hold the mouth frame 8 and extract it as it is without performing any operation.

  In this way, the dust bag detecting body 12 is provided on the lid body 6 to prevent the user from accidentally using the dust bag 9 without setting it in the dust collection chamber 3. Can be attached and detached in one operation. In addition, when the dust bag 9 is mounted, the intake port can be easily seen from above and can be mounted in a stable state. Therefore, erroneous insertion of the dust bag 9 can be prevented. Further, when the dust bag 9 is taken out, it is not caught in the mouth frame and the air intake hole, so that dust in the dust bag is not spilled. In this way, it is possible to prevent the vacuum cleaner from being broken due to dust leakage occurring during erroneous insertion and removal.

  Further, as the lid 6 is in the closed state, the dust bag detecting body 12 is brought into contact with the mouth frame 8 of the dust bag so that the detection unit 12B moves, and the projection 12A can be closed by the movement. Since it is configured to move to the position, a drive source for moving the dust bag detector is not particularly required.

  In addition, the dust bag detector 12 supports the protrusion 12A and the detector 12B so that the dust bag 9 can rotate freely. The protrusion 12A has a dust bag 9 attached to the dust chamber 3 as a detector. The lid 6 is positioned so as not to be in the closed state when it is not detected that the projection 12A is moved, and the protrusion 12A is moved by rotation. This makes it possible to reduce the size.

  Further, the dust bag detecting body 12 is urged by an elastic body so that the protrusion 12A is sandwiched between the tight rib 7 and the packing B5 of the lid and cannot be closed when the dust bag is not attached. Since the lid is always located where the lid cannot be closed, the projection 12A can be inadvertently closed so that the lid remains unattached to the dust bag. Can be prevented from being closed. In addition, there is no gap between the tight rib 7 and the packing B5, so that the dust collection chamber is not tight even if the user turns on the power without attaching the dust bag. It is possible to prevent dust from being sucked in from the suction tool by mistake, and prevent dust from being directly sucked into the electric blower, thereby preventing misuse and improving durability.

  The dust bag detection body is urged by an elastic body so that the protrusion is positioned at a position where the lid cannot be closed when the dust bag is not attached, and the dust bag mouth frame is part of the detection section. To urge the mouth frame toward the air inlet side of the dust collection chamber, and the mouth frame can be brought into close contact with the air inlet even without the mouth frame presser as shown in the conventional example. It is possible to simplify the configuration that eliminates the need for frame pressing.

  In the above-described embodiment, the dust bag detecting body 12 is rotated. However, the protrusion and the detection part slide together by, for example, linking the protrusion and the detection part using a cam mechanism or the like. It may be of any type, and the case where the dust bag detecting body 12 is energized with a spring body and the detecting portion is provided with an engaging portion in order to bring the mouth frame 8 into close contact with the air inlet of the dust collecting chamber will be described. However, a rib for close contact with the mouth frame or the like may be provided on the lid without giving such a function to the dust bag detection body, so long as the object of the present invention is satisfied. Any configuration is acceptable.

  In order to set the dust collection bag 9 in the dust collection chamber 3 in this state, the mouth frame 8 may be fitted to the positioning portion 10 as it is without any operation. In this state, that is, in a state where the mouth frame 8 is set at a predetermined position in the dust collection chamber 3 and the dust bag is inserted, the lid body 6 is rotated so as to be in a closed state. The detection part 12B of the dust bag detection body 12 contacts the upper end part of the mouth frame 8 as shown in FIG. When further rotated to the closed state, as shown in FIG. 7B, the detecting portion 12B starts to rotate upward, and at the same time, the protruding portion 12A rotates to move away from the rib body. Finally, as shown in FIG. 3, the lid body 6 is rotated to a predetermined position to be in a closed state, and the tight rib 7 and the packing B5 are brought into contact with each other to perform air tight. Then, the mouth frame 8 is brought into close contact with the air inlet 2.

  Next, as shown in FIG. 8, when the mouth frame 8 is not inserted into the dust collection chamber 3, the protruding portion 12 </ b> A of the dust collection bag detection body 12 remains the rib body even if the lid body 6 is turned to the closed state. 14, the protrusion 12 </ b> A is sandwiched between the stopper 15 provided in the dust collection chamber 3 and the rib body 14, and the lid body 6 is not completely closed.

  In addition to the operation of the first embodiment, even if the user closes the lid with the mouth frame 8 not attached to the dust collection chamber 3, the protruding portion 12A is sandwiched between the packing B5 and the tight rib 7. Absent. Therefore, since the packing B5 and the tight rib 7 are not damaged by the impact when sandwiching the protruding portion 12A, it is possible to prevent the suction performance from being lowered due to misuse and to improve the durability.

  In addition to the effects of the first and second embodiments, even when the user closes the lid with the mouth frame 8 not attached to the dust collection chamber 3, the protrusion 12A is configured by the soft body 16. Therefore, even if the projection 12A is sandwiched between any part of the lid and the dust collection chamber, it will not be damaged by impact. For this reason, since the restriction on the position of the protrusion 12A is reduced, the protrusion 12A can be disposed at a better position, and the deterioration of the suction performance due to misuse can be prevented and the durability can be improved.

(Embodiment 4)
A fourth embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 11, the protrusion 12A is arranged in the vicinity of the substantially center line of the lid.
