Description

[Detailed Description of the Invention] This invention relates to a vacuum cleaner in which a dust collection case is connected to a main body case in parallel.

Generally, in this type of vacuum cleaner, the dust collection case is connected to the main body case by a locking device, and can be removed from the main body case by operating the locking device.

Furthermore, a rotatable lid for opening and closing the dust disposal opening is provided at the bottom of the dust collection case, a clamp is provided for locking the lid, and the clamp is locked by operating the aforementioned locking device. Some devices are equipped with a release device that releases the state so that dust disposal can be performed with a single touch.

However, with such devices, when removing the dust collection case from the main case or carrying the dust collection case to the dust disposal area, the locking device may be operated until the clamp is released from the locked state. This tends to cause the lid to open and dust to scatter around.

This invention was developed in view of the above points, and the dust collection case can be removed from the main case by operating the locking device, and the lid can also be opened. It is an object of the present invention to provide a vacuum cleaner that prevents dust from scattering due to inadvertence.

This device has a dust collector with a handle formed on the top, a lid that opens and closes the dust disposal opening rotatably attached to the bottom, and a clamp that permanently locks the rotating end of the lid. A case is provided, and a locking device for removably locking the dust collection case to the main body case is provided on the dust collection case, and the locking state of the clamp is released by further pressing the operating portion of the locking device. A release device is provided, and is engaged between the release device and the locking device, and is normally biased to a position where the locking device cannot release the release device, in a direction perpendicular to the direction of movement of the locking device. The present invention is characterized in that a safety device is provided which causes the locking device and the release device to engage with each other by movement.

Therefore, by operating the locking device, the dust collection case is released from the main case and the lid is opened for dust disposal, but a safety device provided separately from the locking device is required. The release device that releases the lid cannot be operated unless operated, and this prevents the user from inadvertently releasing the clamp that locks the lid and opening the opening, and prevents dust from scattering. It is possible to prevent serious accidents from occurring.

An embodiment of this invention will be explained based on the drawings.

Reference numeral 1 denotes a main body case with a built-in electric blower (not shown), and a dust collection case 2 connected to the front end of the main case 1 has a filter section 3 detachably attached to the main case 1 side. is provided.

The filter section 3 consists of a filter frame 4, a suction surface 5 of the filter frame 4 which is a net filter, a sponge-like filter 6 on the inner surface of the suction surface 5, and a filter 7 folded in a zigzag shape.

The periphery of the rear wall 8 of this filter frame 4 is provided with the dust collecting case 2.
A seal backing 9 that maintains airtightness with the inner surface of the main body case 1 is fitted, and a seal backing 11 that maintains airtightness with the front end wall 10 of the main body case 1 is fitted on the opening edge of the rear wall 8. It is fitted.

Further, a handle 12 is formed at the top of the dust collection case 2, a suction port 13 is formed at the front end, and an opening 14 for disposing of dust is formed at the bottom.

Further, a lid 15 for opening and closing the opening 14 is provided with its front end rotatably attached to a hinge 16 provided at the front end of the dust collection case 2.

An L-shaped retaining piece 17 is formed at the rear end of the lid body 15.

On the side of the main body case 1 of the handle 12, a clamp 19, which is a locking device that engages with a retaining hole 18 formed in the main body case 1, slides while its operating portion 20 is urged upward. It is set freely.

Further, the rear wall 8 of the filter frame 4 is used on the side where the dust collecting case 2 is connected to the main body case 1, and the lid body 1 is
A clamp 21 that engages with the engagement piece 17 of No. 5 is rotatably provided while being biased in the locking direction by a spring (not shown).

That is, the protruding piece 22 formed below the rear wall 8 is a supporting member of this clamp 21.

A release device 23 is provided on the connecting portion side of the dust collecting case 2 with the main body case 1 so as to be vertically movable.

This release device 23 is frame-shaped and is urged upward by a spring 25 whose one end is supported by a spring receiver 24 formed on the rear wall 8 of the filter frame 4.

The top of the release device 23 corresponds to the indenter 26 formed on the clamp 19 at a predetermined distance.

A seal backing 27 is provided between the opening edge of the opening 14 and the lid 15.

Therefore, a spring 28 is provided between the indenter 21 of the clamp 19 and the top of the release device 23 so that the blocking portion 2
A safety device 30 is provided which is biased such that 9 is located between the indenter 21 and the top.

This safety device 30 is formed with a notch 31 adjacent to the blocking portion 29 in the biasing direction, and an operating portion 32 is protruded outward while perpendicular to the operating portion 20 of the clamp 19 .

The dust collection case 2 is provided with a compression plate 34 that is biased upward and is movable up and down, with the knob 23 projecting upward to compress dust.

In such a configuration, the dust collected in the dust collection case 2 is compressed by the compression plate 34 by pressing the knob 33.

When disposing of dust, grip the handle 12 of the dust collection case 2 with your left hand.

At this time, in order to operate the operating portion 20 of the clamp 19, it is natural and common to hold the clamp 19 with the thumb facing toward the main body case 1 side.

Therefore, the clamp 19 is disengaged from the engagement hole 18 by the pressing operation of the thumb operation part 20.

If the dust collecting case 2 is lifted as it is, the engagement between the retaining piece 17 and the retaining recess 35 of the main body case 1 will also be released.

At this time, if there is no safety device 30, if the clamp 19 is pushed deeper, the release device 23 will cause the indenter 26 to bend the spring 25 and force the clamp 21 to rotate in the unlock direction, opening the door. 14 is opened and dust is scattered around, but since the blocking part 29 is located between the indenter 26 of the clamp 19 and the top of the release device 23, even if you inadvertently try to push the clamp 19 deeply, it will not work. The pressing force is not transmitted to the release device 23.

The same applies when carrying the dust collection case 2 to the dust disposal area.

Therefore, the opening 14 will not be opened inadvertently and dust will not be scattered.

Next, when the dust collection case 2 is brought to the dust disposal area, the user presses the operating section 32 of the safety device 30 with his or her index finger and deeply presses the operating section 20 of the clamp 19 with his or her thumb.

As a result, the indenter 26 of the clamp 19 passes through the notch 31 of the safety device 30 and presses the top of the release device 23 downward, forcibly releasing the engagement between the clamp 21 and the engagement piece 18.

Then, the lid body 15 rotates around the hinge 16 to open the opening 14 and the dust is thrown away.

At this time, since the operating part 20 of the clamp 19 and the operating part 32 of the safety device 30 are provided close to each other and are orthogonal to each other, the handle 12 can be easily operated with the thumb and forefinger without having to change hands.

Furthermore, since the operating sections 20 and 32 are orthogonal to each other, there is no possibility of inadvertently operating them at the same time.

This invention is equipped with a safety device that can cut off the locking device and the release device as described above, so if this safety device is not operated, even if the locking device is operated, it will not be transmitted to the release device.
Therefore, even if the locking device is operated inadvertently, the locking device of the clamp will not be released and the opening will be opened. This prevents dust from scattering and is sanitary, and the safety device Since the operating section and the operating section of the locking device are provided close to each other, operation can be easily performed with one hand.Moreover, since these operating sections are arranged substantially orthogonally, there is no possibility of erroneous operation and operation can be performed using the thumb and forefinger. It has the following effects:
