Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vacuum cleaner having a push button for opening a front lid for disposing of dust, which is designed to prevent malfunction of the push button.

(Conventional configurations and their problems) Most conventional vacuum cleaners do not have push button malfunction prevention devices, so the push button is often pressed by mistake during cleaning, causing dust to scatter. Even vacuum cleaners equipped with a malfunction prevention device have the inconvenience of having to separate the main body and dust collection box in order to release the device.

C) An object of the present invention is to solve the above-mentioned conventional problems and to provide a vacuum cleaner in which the push button malfunction prevention device 1F can be removed with a simple operation.

(Structure of the Invention) The present invention has a dust collector which has a main body with a built-in electric blower, a built-in dust collector, a lowering hand at the top, a front lid for disposing of dust at the front, and which is detachable from the main body. A box, a hook on the main body side that engages with a part, and an operating part that protrudes above and outside of the lowering hand, and the main body and a dust collection box are arranged to be movable up and down inside the lowering hand. and a push button member for opening the front lid, the push button member having a push button portion near the lowering hand, the push button member having one locking rib. In addition, the push button malfunction prevention member, which has the other locking rib that normally engages with this locking rib, and a lock release operation part that protrudes from the lower outside of the lowering hand, can be moved up and down inside the lowering hand. The lock release operation part is -L.
The above-mentioned object is achieved by releasing the locking of the ribs for opening both ends when the member for preventing malfunction of the push button moves upward when the push button is pushed in the opposite direction.

(Description of Embodiment) Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. Fig. 1 is a sectional view of the main parts of the vacuum cleaner, and Fig. 2 is a sectional view of the lowering part. 1 is a main body with a built-in electric blower 2, and 3 is a main body 1 with a built-in dust collector 4. 5 is a front lid for dust disposal that is provided in front of the dust collection box 3 so that it can be opened and closed freely, and the rib 7 of the buckle armuro is connected to the rib 8 on the side of the dust collection box 3. It engages and normally covers the front of the dust collection box 3. 9 is a lower hand provided on the upper part of the dust collection box 3, and has two protruding bosses], 0, and 11;
A cover 12 is attached above.

Reference numeral 13 denotes a push button member for opening the front lid, which has a push button 14 near the lowering hand 9, and by pushing the push button 14 in the direction of the arrow, rotates around a shaft 15. 1
6 pushes down the buckle arm 6 to release the engagement between the ribs 7 and 8, and as a result, the front cover 5 is rotated forward about the shaft 18 by the spring 17 and opened. Reference numeral 19 denotes a buckle that is movable up and down within the handle 9 and allows the main body 1 and the dust collection box 3 to be detachably separated in the front and back direction. As shown, it is made up of an elongated plate-like member having a horizontal part 20 and a vertical part 21, and the horizontal part 20 has an operating part 22 that protrudes outside the central recess 12a of the cover 12 and a stopper for preventing deformation and regulating the position of the buckle 19. Said protrusion 10.
Two through holes 23 and 24 are formed in the vertical portion 21, and a hook portion 26 that normally engages with a hook portion 25 on the main body side is formed in the vertical portion 21. 27 is the other locking rib that normally engages with one locking rib 28 provided on the push button side and prevents the push button from malfunctioning to stop the rotation of the push button 14; 29 is the locking rib 28 provided on the push button side; This is a lock release operation part that protrudes from the lower part of the lowering hand 9 in order to release the push/k button malfunction prevention by moving it upwards.In this embodiment, the lock release operation part 29 and the lock rib 27 is provided integrally with the buckle 19 as shown in the figure. 3ot/i A coil spring that is interposed between the lowering hand 9 and the operating part 22 of the buckle 19 and urges the buckle 19 upward; 31.32 is the horizontal part 2o of the buckle 19 and the cover 12;
Buckle 19f is interposed between the coil spring 30 and the coil springs 31 and 32, and due to the balance between the coil spring 30 and the coil springs 31 and 32, the buckle 19, which is also equipped with a pushbutton malfunction prevention function, is normally placed in the position shown, that is, in the dust collection position. The hook for attaching and detaching the box 30 is engaged with the locking ribs 27 and 28 for locking parts 25 and 26 and push button malfunction +L, respectively, to release the operation part 22 of the buckle 19 and the push button malfunction prevention. The unlocking operation portions 29 are held in upward and downward protruding positions, respectively.

In the vacuum cleaner configured as described above, when the lowering hand 9 is held in the normal state shown in FIG. Lock release operation part 29 against elastic force
At the same time, the buckle 19 moves upward, and the locking rib 27 formed at its tip also moves upward, resulting in the state shown in FIG. 5, and the engagement of the locking ribs 27 and 28 is released. As a result, there is no obstacle to the rotation of the push button member 13, and the front cover 5f can be opened by operating the push button part 14 at any time. In other words, when you want to know the amount of garbage or when disposing of garbage, hold the lower hand 9 with one hand and press s.
The front cover 5 can be opened simply by pressing the p-ton part 14.

In addition, when the buckle for attaching and detaching the main body/dust collection box and the member for preventing malfunction of the push button are integrated as in this embodiment, when the main body 1 and the dust collection box 3 are connected, the lowering hand 9 can be used to clean the vacuum cleaner. When holding the buckle 19, the upward movement of the buckle 19 increases the hooking distance between the buckle side and the body side hooking portions 26 and 25, so there is no risk of the buckle malfunctioning causing the body and dust box to separate and the body falling. .

In addition, when separating the main body 1 and the dust collection box 3, push the operating part 22 of the buckle 19 and move it downward as shown by the dotted line in Figure 2, and release the hook parts 25 and 26. It is done.

(Effects of the Invention) As described above, according to the present invention, it is possible to prevent the malfunction of the push button normally used to open the front cover, and to grasp the lower hand with one hand when checking the amount of garbage or when disposing of garbage. The button malfunction prevention device can be released by simply pressing the button, and the front cover can be opened with a single touch using one hand. In addition, when carrying the vacuum cleaner with the main body and dust collection box combined, holding the lower hand, the latch of the buckle between the main body and the dust collection box increases, which may cause the main unit to fall and cause injury during transport. can also be prevented.
