Description

[Detailed description of the invention] The present invention relates to a vacuum cleaner.

Conventionally, there are vacuum cleaners in which a dust collection bag can be set in the dust collection chamber in order to easily dispose of the garbage in the dust collection case, but when opening the lid and taking out the dust collection bag by hand, the user's hands are If there is dirt or a dust disposal opening is formed on the bottom surface, it is troublesome to take out the dust collection bag, and there is a risk of dirt spilling out of the dust collection bag, which is unsanitary. This invention was made in view of these points, and when using a dust collection bag, it is possible to use the dust collection bag to collect dust without spilling garbage or getting your hands dirty, and without fear of tearing the dust collection bag. The purpose is to create a vacuum cleaner that can be taken out of the case.

In this invention, when the dust collection bag is used, the mounting flange of the dust collection bag is held between the lid attached to the dust collection case and the dust compression plate, and when the dust is to be disposed of, the dust compression plate is linked to the opening operation of the lid. Slide the dust collection bag toward the dust disposal opening, and the dust compression plate pushes out the dust collection bag together with the mounting flange toward the trash can, etc., so you can throw away dust with one touch without getting your hands dirty or spilling the dust. The structure is designed to prevent the dust collection bag from tearing as well as to prevent the dust collection bag from tearing.

An embodiment of the present invention will be described based on the drawings.

1 is an electric case housing an electric blower 2, and a dust collection case 4 is removably attached to one end of this electric case 1 with a clamp 3.The dust collection case 4 has both side walls 5 facing downward. It has a trapezoidal shape that expands toward the front, and a suction port 7 is formed in the front wall 6.
An end frame 9 having a suction port 8 is attached to the front surface of the dust collection case 4. Furthermore, a dust collection chamber 11 in which a filter unit 10 is inserted is formed inside the dust collection case 4, and a dust compression plate 12 is held in the upper part of the dust collection case 4 so as to be movable up and down. This dust compression plate 12 is fixed to the lower end of an operating piece 14 which is urged upward by a spring 13. Furthermore, a dust disposal opening 15 is provided at the bottom of the dust collection case 4.
Lids 16 and 17 for opening and closing are rotatably attached. A turning wheel 18 is attached to one lid 17. Next, an opening/closing operation plate 19 as an opening/closing operation body is inserted between the front wall 6 of the dust collection case 1 and the end frame 9 so as to be movable up and down, and the lid is attached to both sides of the opening/closing operation plate 19. 16,
A wire 20 for suspending the operation piece 17 is attached, and a vertically long escape opening 21 is formed in the center from which the cylindrical suction port 8 projects, and the upper part is joined to the upper surface of the projection piece 22 of the operation piece 14. A protruding piece 23 is formed as an operating section.

A pair of left and right leaf springs 24 elastically connected to both sides of the front wall 6 of the dust collection chamber 11 are fixed to the both side walls 5.

A mounting flange 26 made of cardboard or the like fixed to the opening edge of the breathable dust collection bag 25 opens the opening 26a to the front wall 6 by the leaf spring 24 in correspondence with the suction ports 7 and 8.
is pressed against. Both upper and lower edges of the mounting flange 26 are held between the dust compression plate 12 and the lids 16 and 17. Note that the operation piece 14 and the opening/closing operation plate 19 are located near the handle 27 of the dust collection case 4.

In such a configuration, by driving the electric blower 2, outside air containing dust is discharged from the suction ports 7 and 8 to the dust collection bag 25.
It is stored in

When discarding the dust collection bag 25 along with the garbage, the suction hose (not shown) is pulled out from the suction port 8 and the opening/closing operation plate 19 is pushed down. Thereby, the wire 20 pushes down the lids 16 and 17 in the opening direction. At this time, since the protrusions 22 and 23 are joined together, the dust compression plate 12 pushes down the mounting flange 26 in conjunction with the opening operation of the lids 16 and 17, and thereby the dust collection bag 25 is placed in a predetermined position such as a trash can. be discarded at a location. The opening operation of the lids 16 and 17 and the operation of taking out the dust collection bag 25 are performed by using the fingers of the hand holding the handle 27 on the opening/closing operation plate 1.
All you have to do is press 9, so it's a one-touch operation and doesn't get your hands dirty. Since the mounting flange 26 is pushed down along the front wall 6 while the dust disposal opening 15 also faces downward, dust is difficult to spill out. In addition, since both side walls 5 of the dust collection chamber 11 expand downward, the dust collection bag 25 will not be torn due to frictional force with the side walls 5. When the user releases the opening/closing operation plate 19, the force of the spring 13 causes the dust compression plate 12 and the opening/closing operation plate 19 to return upward, and the lids 16, 17 are lifted up to close the dust disposal opening 15. When setting a new dust collection bag 2J5, insert the mounting flange 26 through the dust disposal opening 15 with the lid open, sandwich it between the front wall 6 and the leaf spring 24, and then attach the upper and lower edges of the mounting flange 26 to the lid 16, 17
and the dust compression plate 12. In this state, the mounting flange 26 is pressed against the front wall 6 by the force of the plate spring 24, and the airtightness with the suction port 7 is also high. Furthermore, when cleaning without using the dust collection bag 25, the dust is collected in the space in front of the filter unit 10, but if necessary, by pressing the operation piece 14, the dust compression plate 12 is able to remove the dust inside. Compact with trash.

When disposing of dust, carry the dust collection case 4 to the designated location,
Push the opening/closing operation plate 12 to open the lids 16 and 17. At this time as well, since the dust compression plate 12 is lowered, the dust accumulated inside is pushed out by the dust compression plate 12, and the resistance to push out the compressed dust due to the slope of both side walls 5 is also small. Since this invention is configured as described above, by closing the lid of the dust collection case, the mounting flange of the dust collection bag can be fixed between the lid and the dust compression plate, and by opening the lid, the dust compression plate can be fixed. The plate, together with the mounting flange of the dust collection bag, pushes the dust collection bag towards the dust disposal opening, so there is no risk of tearing the dust collection bag, and dust disposal can be done with one touch without getting your hands dirty. This has the effect of preventing spillage.
