Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention is characterized in that the member forming the front edge of the suction port can slide up and down to change the shape and size of the dust collection suction port. This invention relates to an improvement of a floor suction device for a monkey vacuum cleaner.

(B) Conventional technology The floor suction device of a vacuum cleaner needs to minimize the gap between the dust collection suction port and the floor in order to increase the negative pressure inside the main body and ensure dust collection power. was there. On the other hand, when the amount of dust to be sucked in is large, the member defining the front edge of the suction port is configured to be able to slide up and down to allow the large amount of dust to be sucked in. However, when the member is slid upward in response to large particles, the negative pressure inside the main body becomes low, resulting in a drawback that the deep suction performance becomes extremely poor.

Furthermore, the floor suction device disclosed in Japanese Patent Application Laid-Open No. 59-211421 has a protrusion that can slide up and down the member that partitions the front edge of the suction port to change the shape and size of the dust collection suction port. However, this protrusion is located in front of the suction port, and the distance from the front edge of the suction port to the front of the main unit is large, so when cleaning the vertical wall of a room:
The front part of the main body hits a vertical wall and cannot collect dust by the distance from the front edge of the suction port to the front part of the main body, and the larger the distance, the larger the part that cannot be collected.

(c) Problems to be solved by Part 8A This invention improves the suction performance of large dirt, does not reduce the deep suction performance, and is easy to move, and furthermore, when cleaning the vertical walls of a room.

To provide a floor suction tool for a vacuum cleaner, which has a small part where dust cannot be collected.

B) Means for Solving the Problems The floor suction tool for a vacuum cleaner of the present invention is provided with a connection part with a suction pipe at the rear of the main body, and a suction port for collecting dust at the front bottom of the main body, The front vertical plate of the main body, which defines the front edge of the dust collection suction port and constitutes the inner wall of the dust collection suction port, is supported so as to be slidable in the vertical direction relative to other parts of the main body, and K. A shielding plate is disposed at the rear of the dust collection suction port so as to be slidable up and down, and the shielding plate is interlocked with the front vertical plate so as to slide in the opposite direction to the front vertical plate. It is said that

(e) Function Under normal conditions, the front vertical plate is lowered to create a smaller gap with the floor, and at this time the shielding plate is raised. When sucking in large debris, the front vertical plate slides completely upwards, increasing the gap between the front vertical plate and the floor, while the shielding plate simultaneously slides downward, reducing the gap with the floor. The negative pressure inside the floor suction does not become low.

Only the front vertical plate is disposed in front of the front edge of the dust collection suction port, and since the distance from the front edge of the suction port to the front of the main body is small, the amount of dust left after collecting is small.

(f) Example As shown in FIGS. 1 to 8, the floor suction tool 1 of the vacuum cleaner has a main body 2, a bend 8 which is a connection part with a suction pipe (not shown), and a bottom plate of the main body 2. Lower case 4 and main body 2
A dust collection suction port 6 defined by a front vertical plate 5 that slides vertically with respect to other parts of the screen, and a shielding plate 7 that slides vertically and is disposed behind the suction port 6. and a sliding means that slides in conjunction with the front vertical plate 5 and the shielding plate 7 in the vertical direction and in mutually opposite directions.

The main body 2 has a box-like structure, with a suction chamber 9 and a turbine chamber 10 formed inside by a lower case 4 and an upper case 8. A rotating brush 11 is rotatably supported in the suction chamber 9, and an air turbine 12 is rotatably supported in the turbine chamber 1O.

The bend 8 is attached to the main body 2 via a bend cover 18. The pend cover 18 can freely rotate up and down relative to the main body 2. Bend 8 is a pend cover 18
The pend cover 18 is rotatable in the axial direction.

The front vertical plate 5 has approximately the same width as the width of the suction port 6, and is supported so as to be slidable in the vertical direction by a sliding means. 14 is an inclined portion of the front vertical plate 5.

The shielding plate 7 has an elastic lip 15 at its lower end, an opening 16 provided in the lower case 4 and a lip 17 in the upper case 8.
18, it is supported so as to be slidable in the vertical direction by a sliding means.

The main part of the sliding means is disposed above the front vertical plate 5. The sliding means includes a lip 19 of the lower case 4 and a rib 20 of the upper case 8 into which the front vertical plate 5 is inserted and positioned for longitudinal and horizontal direction, and a first inclined groove provided diagonally on the rear surface of the front vertical plate 5. 21 and an adjustment plate 28 having a first bin 22 that fits and moves in the first inclined groove 21, and adjusts the adjustment plate 28 in the left-right direction while maintaining the fitted state between the first bin 22 and the first inclined groove 21. A rib 20 of the upper case 8 that is slidably supported, and a presser member 24 of the lower case 4,
A second inclined groove 25 is provided on the upper front surface of the shielding plate 7 in a direction opposite to that of the first inclined groove 21 and extends rearward from the adjustment plate 28 and moves while fitting into the second inclined groove 25. It consists of a second bin 26. Reference numeral 27 denotes a sliding knob for the adjustment plate 28, which protrudes from an opening 28 provided in the upper case 8.

In addition, 29 is a bumper attached around the main body 2, 80 is a front wheel, 81 is a rear wheel, and 32 is a switching lever for switching between carpet use and folding use.

The floor suction tool 1 for a vacuum cleaner according to the present invention is configured as described above. Therefore, when the amount of dust to be sucked in by the vacuum cleaner is small, the main body 2 as shown in Figs.
The front vertical plate 5 is used in the lowest position relative to other parts. At this time, the gap (A) between the front vertical plate 5 and the floor becomes smaller, and the second bin 26 of the adjustment plate 28 of the shielding plate 7 fits into the lowest part of the second inclined groove part 25. Therefore, it is located above, and there is a gap (B) between it and the floor, which maintains appropriate deep suction performance as a whole and prevents the negative pressure directly facing the suction from becoming too high and causing poor mobility. To prevent.

Next, if the vacuum cleaner has to suck up a large amount of dust,
Operate the slide knob in the direction of the arrow in Figure 5), 1st
Slide the adjustment plate 28 so that the pin 22 comes to the bottom of the first inclined groove part 21. The front vertical plate 5 has a first inclined groove portion 21
is supported by the first bin 22 and slides upward relative to the other parts of the main body 2, creating a large gap (C) between it and the floor. At this time, by sliding the adjustment plate 28, the second bin 2
6 moves horizontally, and the second inclined groove portion 25
The second bin 26 fits into the top of the second inclined groove 25, the shielding plate 7 is positioned downward, and the gap (D) between it and the floor becomes smaller and the second bin 26 is placed directly in front of the suction. prevent the negative pressure from becoming low. 7 to 9 show a state in which the front vertical plate 5 has slid upward and the shielding plate 7 has slid downward. By using the front vertical plate 5 in this state, the user can avoid sucking in large pieces of dirt.

The height of the front vertical plate 5 can be changed relative to the other parts of the main body 2 by sliding the adjustment plate 28 according to the size of the dust to be sucked in, so that the front vertical plate 5 can always be placed directly in the direction of the suction. Negative pressure can be obtained, easy to move, and effective deep suction performance can be obtained. Also, during normal use, the shielding plate 7
By raising lip 15, lip 15 is raised.
5 will not wear out.

(G) Effects of the Invention According to the present invention, even if the shape and size of the dust collection suction port change depending on the size of the dust to be sucked, the same appropriate negative pressure can always be obtained, improving the suction performance for large dust. It is possible to obtain a floor suction tool for a vacuum cleaner that is easy to move, has no deterioration in deep suction performance, and is easy to move. Furthermore, since the distance from the front edge of the suction port to the front of the main unit is small,
When cleaning the vertical walls of a room, the area where dust cannot be collected can be kept small.
