Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION The present invention relates to a vacuum cleaner whose dust disposal opening is closed with a lid.

Technical Background and Problems Conventionally, in this type of vacuum cleaner, in order to open the lid that blocks the dust disposal opening, one has to grasp the dust case with one hand and push the lid with the other hand. The clamps on the body must be removed. Therefore, it is easy to get your hands dirty with dust during operation, and furthermore, the opening position during operation is close to your face, which is unhygienic.

OBJECTS OF THE INVENTION An object of the present invention is to provide a vacuum cleaner that allows the lid to be opened while holding the dust case with one hand.

Embodiment of the Invention An embodiment of the present invention will be explained based on the drawings. Reference numeral 1 denotes a main body case that houses an electric blower 2 and a cord reel 4 around which a cord 3 is wound, and has wheels 5 on both sides of the lower part. Next, a dust case 9 is provided in which a suction port 6 and a concentration chamber 8 having an open lower surface are formed. ,
The dust collection chamber 8 is provided with a filter unit 10 and a compression plate 11 that moves up and down while being forced upward. Further, a dust removal body 14 is provided on the exhaust side partition wall 12 of the dust case 9, and the dust removal body 14 rotates by inheriting the rotation of the cord reel 4 via a gear 13. ] A backing 16 is provided which joins to the partition wall 15 on the suction side. A backing 17 is also attached to the opening edge of the dust case 9. A through hole 18 is formed in the partition wall 15 of the main body case 1, a through hole 19 is formed in the dust removing body 14 (FIG. 2), and a through hole 19 is also formed in the partition wall 12 of the dust case 9 (not shown). It has holes. Thus, a lid body, ie, a stone lid 21, is provided to which a pivot shaft 20, which is a wheel, is attached. Near one end of the bottom cover 21 on the exhaust side, as shown in FIG. A pinion 23 and a fulcrum shaft 24 are formed, and a locking protrusion 25 that projects downward from the center is formed. On both sides of the lower part of the partition wall 12 of the dust case 9, there is a holding part 26 which serves as a U-shaped shaft attachment part that holds the fulcrum shaft 24 rotatably in a vertical plane and movable back and forth on a horizontal plane. It is formed. Also, on the lower suction side of the dust case 9, there is an engaging portion 21a at the free rotation end of the bottom cover 21 as shown in FIG.
A locking portion 27 is formed which engages with the backing 17 and supports the bottom lid 21 from below.

Further, a recess 28 having a depth a is formed on the upper surface of the bottom lid 21 and approaches the substantially inside side of the exhaust side of the backing 17. Thus, the dust case 9 is prevented from moving in the front-rear direction by fitting the locking protrusion 25 of the bottom cover 21 into a fixed locking portion 29 formed at the lower part of the main body case 1. It is connected to the main body case 1 by engaging the latch portion 32 of the movable locking body 31 provided near the handle 30 in the locking hole 33 of the main body case 1. A transmission body 34 is provided that moves up and down along the partition walls 1 and 2 of the dust case 9.

As shown in FIGS. 2 and 3, this transmitting body 34 has a pair of left and right legs 35, and these legs 35 have a notch 36 shaped like a sling 1 through which the hinge piece 22 of the bottom cover 21 enters and exits. Elongated holes 37 are formed to hold both ends of the fulcrum shaft 24 rotatably and relatively movable up and down, and the upper portions of the elongated holes 37 are inclined upwardly toward the partition wall 12. A slope 38 is formed. Also, a rank 39 is formed on the inner surface of these leg portions 35, as shown in FIG. 8, and engages with the pinion 23. On the upper side of this rack 39, there is a slope 40 formed on the outer periphery where the teeth of the pinion 23 are not formed.
A slope 41 is formed that abuts against the fulcrum shaft 24 and presses the fulcrum shaft 24 toward the partition wall 12 when the abutment occurs.

Next, the exhaust side of the handle 30 of the dust case 9 is covered with a plate 42 as shown in FIG.
The upper end thereof and the movable locking member 31 are elastically connected to each other with a compression spring 45 interposed therebetween, so that the two can move together or independently. Further, in the internal space 43, an operating section 46 serving as a push button is provided so as to be slidable in the left and right directions while being biased in the return direction by a compression spring 47. As shown in FIGS. 4 to 7, the movable locking body 31 is locked with four parts 48 formed at the upper center of the operating portion 46 when it is locked with the locking hole 33 of the main body case 1. A lock portion 49 and a claw 50 are formed by a protrusion that locks the sliding operation of the operating portion 46. The operating portion 46 also includes a claw 51 that engages with the upper side of the claw 50, a locking portion 53 that engages with the upper surface of the claw 52 of the transmission body 34 to lock its movement in the opening direction (upward), and The pushing operation of the portion 46 causes the transmission body 34 to
A suppressing portion 55 is formed which abuts against and scoops up the claw 54.

In such a configuration, the state in which the movable locking body 31 is locked in the locking hole 33 of the main body case 1 is the state in which the movable locking body 31 is shown in the imaginary line in FIG. In this case, the lock portion 49 protrudes into the recess 48 and prevents the sliding operation of the operating portion 4G. Movable staff i
When the dust case 9 is moved away from the main body case 1 by pushing the unit 31, the movable locking body 31 is raised by the force of the compression spring 45 until its claw 50 comes into contact with the claw 51 of the operating part 46 (Fig. 4), and the lock part 49 is withdrawn from the recess 48.

to release the operating section 46. The bottom cover 21 is pressed against the backing 17 by the locking part 27, and the gravity of the bottom cover 21 and the pivot shaft 20 does not act as a driving force for the opening operation. However, when the operating part 46 is pressed, the first Claw s shown in Figure 4
o and st are released, and the movable locking body 31 is further retracted upward by the force of the compression spring 45. Then, the lock portion 53 releases the transmission body 34, and the transmission body 34 is moved by the force of the compression spring 44 and the operation portion 46. The pressure increases due to the pressing force of the suppressing portion 55. When the amount of pressure reaches T, it means that the transmitting body 34 is
This means that the fulcrum shaft 24 has risen from the position a) to the position shown in FIG. Just slide.

In other words, the engaging portion 21a at the free rotation end of the bottom cover 21 is connected to the locking portion 2.
Freed from 7. At this time, the bottom cover 21 is removed as shown in FIG. 8(b).
Because the four parts 28 are formed as shown in the figure, the bottom cover 21 can be easily separated from the backing 17, so the force required to slide the bottom cover 21 is small. This allows the bottom cover 21 to be brought into pressure contact with the backing 17 with a strong force during closure, thereby improving sealing performance. In this way, after the bottom cover 21 and the locking part 27 are disengaged, the bottom cover 21 is urged in the opening direction by its own weight and the weight of the rotation @2o, so it cannot rotate about the holding part 26 as a fulcrum. , the pinion 23 engages with the rack 39, so it bottoms out from the position shown in FIG. 8(c) to the position shown in FIG. 8(d)! 2
1 rotates. In this process, the transmission body 34 is connected to the movable locking body 3.
It moves independently and is not linked to 1. When the lid is opened and the dust is thrown away, the compression spring 4 increases when the movable locking body 31 is pressed.
5, the transmission body 34 is interlocked and lowered. Therefore, by an operation opposite to the opening operation, the bottom cover 21 rotates in the closing direction and joins to the backing 17 of the dust case 9, and then slides in the joined state and moves forward (to the left in FIG. 1). The engaging portion 2 ] a slides and engages with the locking portion 27 . In this state, unless the operation part 46 is pressed, the transmission body 3
4 is locked in the opening direction, and the downward movement of the transmitting body 34 is locked by the joining of the slopes 40 and 41 as shown in FIG. 8(a). At this time, the fulcrum shaft 24 is also 2
1 and the locking part 27 is suppressed in the direction of increasing, therefore, the bottom cover 21 has a high airtightness and is securely locked, and dust remaining in the dust case 9 is prevented from spilling. This series of operations is possible by arranging the movable locking body 31 and the operation part 46 near the handle 30 of the dust case 9, making it easy to attach and detach the main case 1 and the dust case 9 and to open and close the bottom cover 21 with one hand. Even if the stroke between the movable locking body 31 and the transmission body 46 is small, the bottom cover 21 can be opened and closed widely by the engagement between the rack 39 and the pinion 23. That is, the pressing force of the bottom cover 21 against the backing 17 is sufficient, the airtightness is improved, and the amount of protrusion of the movable locking body 31 is also reduced, thereby improving the aesthetic design. Also,
Since the lid 21 is held by the holding part 26 and the locking part 27, it will not open or lose its airtightness even if it is biased in the opening direction and receives pressure from the compression plate 11 when compressing dust. Never. Then, the locking protrusion 25 of the bottom cover 21 is fitted into the fixed locking portion 29 of the main body case 1, and the movable locking body 31 is pushed and locked in the locking hole 33, thereby connecting the main body case 1 and the dust case 9. However, this state is the seventh
As shown in the figure, the lock part 49 of the movable locking body 31 is connected to the operating part 46.
Therefore, in this state, a force in the longitudinal direction is applied to the bottom cover 21 due to the frictional force between the rotation @2o and the bottom surface, but as described above, the fulcrum shaft 24 of the bottom cover 21 is locked. The long hole 37 of the transmitting body 34 prevents movement in the front-back direction, and the free end edge of the bottom cover 21 engages with the locking part 27.
In addition, the protrusion 25 is prevented from moving back and forth by the fixed locking portion 29, so that the bottom cover 21 and the locking portion 27 are prevented from moving back and forth.
The rap will never come off. This locking protrusion 25 is
Since the fixed locking portion 29 is surrounded by a 90-inch ring, the design beauty is not impaired, and since the dust case 9 is opened when the dust case 9 is separated from the main body case 1, opening and closing operations of the bottom cover 21 are not required more than 1 times.
There is no way to set it to 1.

Effects of the Invention As described above, the present invention provides a cover for closing the opening of the case to the dust case 1 so that one end thereof is pivotally supported by the dust case and the other end engages with the locking part. A push button for releasing the engaging part from the locking part of the dust case is provided near the handle, so you can easily open the lid while holding the dust case with one hand, and this allows you to free your hands when disposing of the dust. It does not get dirty and the opening is located away from the face, so it is hygienic.
