Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner equipped with a dust collection case that is separated from an electric power case.

Conventionally, in this type of vacuum cleaner, a handle is formed on the top of the dust collection case so that the dust collection case can be easily carried after being removed from the electric case. Generally, an opening is formed in the dust collection case to discard the dust accumulated in the dust collection chamber, and this opening is closed with a lid. Therefore, the lid is opened by gripping the lid, but this has the disadvantage that dust scatters as soon as the lid is opened, staining the hands. For this reason, it has been considered that a push button is provided near the handle, and the lid is opened by operating this push button, but in this case, both are connected in order to transmit the movement of the push button to the lid. The disadvantage is that the cover has to be placed close to the dust collection case, the lid is located at the front or rear of the dust collection case, and the direction of dust emission is horizontal, resulting in poor operability. This invention was made in view of the above points, and it makes disposing of dust extremely hygienic and
To provide a vacuum cleaner that can be operated with good operability.

In this invention, by grasping the handle formed on the upper part and operating the push button, the lid that closes the lower opening of the dust collection case can be opened via the operating member. It is possible to dispose of dust by dropping it downward, and its operability is extremely good.Moreover,
Since the operating member is located between one end wall of the dust collection chamber and the end frame serving as the outer wall, dust does not adhere to the operating member and smooth operation can be maintained. In addition, a suction port is formed in one end wall of the dust collection chamber and an end frame located on the outer surface of the dust collection chamber, and an escape opening for escaping the suction port is formed in the operating member connecting the push button and the lid. The front part of the filter unit can be used to connect the push button and the lid, and the structure can be simplified without complicating the mounting surface with the electric case to which the filter unit is attached. It is composed of An embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes an electric case that houses and holds an electric blower 2, and a dust collection case 4 is detachably attached to one end of the electric blower 1 with a clamp 3.

This dust collection case 4 has both side walls 5 and one end wall 6 shaped into a trapezoid that expands downward, and has a dust collection chamber 4b.
A suction port 7 is formed in one end wall 6 of the housing. Further, the dust collecting case 4 includes an end frame 9 having a cylindrical suction port 8 formed on the front surface thereof. A filter unit 10 is housed and held on the electric case 1 side of the dust collection case 4, and a compression plate 11 is provided on the upper part so as to be vertically movable. This compression plate 11 is fixed to the lower end of the operating piece 13 which is urged upward by a spring 12. Further, at the bottom of the dust collection case 4, there are lids 15, 16 for opening and closing the opening 14.
is rotatably mounted on both sides. A steering wheel 17 is attached to one lid 16. Next, a plate-shaped structure is provided between the dust collection case 4 and the end frame 9 to push open the lids 15 and 16! A movable member 18 is inserted so as to be vertically movable. That is, the lids 15 and 16 each have a wire 19
It is held in a suspended state by the operating member 18. This actuating member 18 has a vertically long relief opening 20 formed in the center to allow the suction port 8 to escape, and a protruding piece 22 that joins to the upper surface of the protruding piece 21 of the operating piece 13 is formed in the upper three parts. ing. A handle 4a is formed at the top of the dust collection case 4,
A push button 18a located near the handle 4a is integrally formed on the upper part of the operating member 18.
4. In such a configuration, the spring 12 urges the compression plate 11, the operating piece 13, and the actuating member 18 upward, so that the lids 15, 16 are suspended from the actuating member 18 via the wire 19. The opening 14 is closed. Then, cleaning is performed by connecting suction hoses (not shown) to the suction ports 7 and 8 and driving the electric blower 2, and the dust 23 is sequentially deposited on the bottom of the dust collection case 4, that is, on the lids 15 and 16. It can be accumulated. Then, by removing the suction hose and pushing the operating piece 13, the compression plate 11 is lowered to compress the dust 23. When the user releases the operating piece 13, the compression plate 11 returns to its original position, but since the dust 23 is compressed from top to bottom, it remains stable without collapsing even if the compression plate 11 is retracted. Then, the dust collecting case 4 is removed from the electric case 1, the handle 4a is grasped, the dust 23 is carried to a place where the dust 23 is to be thrown away, and the lids 15 and 16 are opened, and the dust 23 is thrown away. At this time, since the opening 14 is formed directly below, there is no need to change the orientation of the dust collecting case 4, and the dust 23 is released in the compressed direction, resulting in less dust flying up, which is sanitary. In addition, when the push button 18a is pressed and the actuating member 18 is pushed down, the lids 15 and 16 open while pushing down the compression plate 11, so the work of discarding the dust 23 can be done much more easily without having to pick up the dust by hand. be exposed. Furthermore, since the dust collection case 4 expands downward, the resistance to push out dust is also small. Even in this case,
When the push button 18a is released, the actuating member 18 and the compression plate 11 are returned to their original positions by the force of the spring 12, and the lids 15 and 16 are also connected to the wire 1.
It is drawn to 9 and closes. Since the present invention is configured as described above, by grasping the handle formed on the upper part and operating the push button, the lid closing the lower opening of the dust collection case is opened via the operating member. As a result, the dust can be disposed of by dropping the dust downward, and its operability is extremely good.Moreover, the operating member is connected to one end wall of the dust collection chamber and the end frame that becomes the outer wall. Since the operating member is located between one end wall of the dust collection chamber and the other end located on its outer surface, it is possible to maintain smooth operation without dust adhering to the operating member. A suction port is formed in the frame, and an escape opening for letting the suction port escape is formed in the operating member that connects the push button and the lid, so that the push button and the lid can be connected using the front part of the dust collection case. This has the advantage of simplifying the structure without complicating the mounting surface to the electric case to which the filter unit is attached.
