Abstract

PURPOSE:To avoid an obstacle smoothly, and to improve the traveling performance by a method wherein a cleaner main body is supported free to rotate in either the right or left circumferential direction on a carrier which first comes in contact with the obstacle when the cleaner main body moves on a surface to be cleaned. CONSTITUTION:When a suction hose 30 is pulled in the direction shown by an arrow P in such a state that a bumper 17 and an elastic cover 17a come in to contact with an obstacle A, a stand 8 turns to get away from the obstacle A, so that a cleaner main body 1 is able to move even in a room where many pieces of furniture, etc., are located. As the rotating angle of the cleaner main body 1 on the stand 8 is restricted by a stopper, a cord 3 does not wind around the stand 8 several times. In case the stand 8 is in a fixed state on a shaggy carpet, the main body 1 rotates on the stand when the suction hose 30 is pulled to the right and left, so that the cleaner main body easily shifts the direction. As the gravity center of the cleaner main body 1 is located near the surface to be cleaned, and legs 9 are protruded out, the cleaner main body does not tumble over and smoothly travels in the direction the cleaner is pulled.

At this time, when you pull the suction hose, the mounting table rotates and moves, and the vacuum cleaner body moves in the direction away from the obstacle. The vacuum cleaner body and the mounting table run on the surface to be cleaned in the direction pulled by the suction hose.

Even if the mounting base becomes almost fixed on the surface to be cleaned.

Pull the suction hose in the circumferential direction of the vacuum cleaner body.

Since the fitting part of both the mounting table and the vacuum cleaner body is almost a perfect circle, the vacuum cleaner body rotates smoothly on the mounting table, and
The suction hose and the vacuum cleaner body rotate slightly on the mounting table. If at least the upper part of the vacuum cleaner main body is hemispherical, the suction hose can be made to have a smaller turning radius.

Furthermore, if a large electric blower or a cord reel of one weight is placed at the bottom of the vacuum cleaner body, the center of gravity of the vacuum cleaner body approaches the surface to be cleaned, and the running of the vacuum cleaner body becomes stable. In addition, if the suction hose is attached to the vacuum cleaner body, and the attachment part of the suction hose faces downward, the tilt of the vacuum cleaner body when the suction hose is pulled will be reduced, and the vacuum cleaner body will be prevented from flipping over. do. Furthermore, if the legs are made to protrude outward from the side wall of the cylindrical mounting base, the inner bottom of the cylindrical mounting base can be brought closer to the surface to be cleaned, and the vacuum cleaner body placed on the cylindrical mounting base can , to get closer to the surface to be cleaned.

The vacuum cleaner body rotates on the mounting table, but the rotation angle is
The rotation angle is controlled to a predetermined angle by the rotation angle regulating means.

Therefore, the i'awX cord does not become entangled with the vacuum cleaner body or the mounting table, and no excessive force is applied to the power cord.

Since the vacuum cleaner main body is formed from a hemispherical upper case and a bottomed cylindrical lower case, a vacuum cleaner main body with a round external design can be easily manufactured.

Moreover, if the vacuum cleaner main body is formed from two cases, an upper case and a lower case, and the lower end outer periphery of the upper case is flush with the outer periphery of the mounting table or located outward from the outer periphery of the mounting table, the outer periphery of the upper case Prevents dirt from entering the mounting table.

When the vacuum cleaner body runs, the lower surface of the legs projecting outward from the stand is covered with a bowl-shaped mounting frame, the mounting frame functions as a sled, and the legs easily get over the threshold.

While the electric blower is operating, the exhaust flow from the electric blower is

The suction hose can be moved close to the surface to be cleaned, and the legs 9 are made to protrude outward from the side wall of the mounting table 8, and the casters 10 are attached to the legs 9. It follows the direction of the pull and runs smoothly.

Furthermore, if the member 13 with a circular cross section, such as a small wheel, is damaged due to long-term use and you want to replace it with a new member with a circular cross section, turn the vacuum cleaner body 1 over.
By removing the fasteners 14, the mounting table 8 is separated from the cleaner body 1. When the mounting table 8 is separated, the vacuum cleaner main body 1
Since the member 13 with a circular cross section provided on the outer bottom is exposed, the damaged one of the exposed member 13 with a circular cross section can be removed and replaced with a new member with a circular cross section.

Furthermore, in assembling the vacuum cleaner main body 1 and the mounting table 8, first, the hemispherical upper case 1a is held horizontally using a Yato. In addition, inside the case la, there is an inner case 45.
Code reel 4. Attach the sound insulation case 22 and electric blower 2. Thereafter, a bottomed cylindrical lower case 1b having a circular cross-sectional member 13 (small wheels) attached thereto is attached to the upper case 1a. Finally, if you cover the lower case 1b with the mounting table 8 which is equipped with casters in advance and rotatably attach the mounting table 8 to the lower case 1b,
All assembly work is completed.

Although each structure has been specifically described in the above embodiments, other structures may be used as long as they can achieve the same effects as the present invention.

For example, the member 13 having a circular cross section may be rotatably attached to the mounting table 8 side, or may be arranged between the outer wall of the lower case 1 and the inner wall of the mounting table 8.

If noise reduction is not an issue, as shown in another embodiment of FIG. Exhaust port 1 that discharges from the side of 100
03 may be arranged in a positional relationship such that the exhaust flow is discharged diagonally to the rear left when viewed from the suction port 102. With this arrangement, the exhaust air is less likely to be blown onto the user's feet or the like. As in the other embodiment shown in FIG. 12, when the exhaust port 103 is used to discharge the air directly to the outside from the side surface of the cleaner main body 100, the mounting table 8 does not need to have a cylindrical shape with a bottom.
It doesn't matter if there is a hole in the bottom. The number of legs 9 and casters 10 is not limited to four, and may be three or five or more. The cross-sectional circular member 13 is also 3
The number is not limited to 4 or more, but may be 4 or more.

Furthermore, if the lowering of the center of gravity of the vacuum cleaner body 1 can be sacrificed a little, the legs 9 may be made to protrude from the bottom of the mounting table 8 to the outside of the mounting table 8. Furthermore, if only the ability to avoid obstacles is important and it is acceptable to sacrifice a little improvement in preventing the vacuum cleaner body 1 from flipping over, it is possible to eliminate the leg portions 9 in the cylindrical mounting table 8. Casters 9 may be attached to the lower surface of the stand 8. e If the outer circumferential diameter of the mounting table 8 is made much larger than the outer circumferential diameter of the vacuum cleaner main body 1, casters 9 can be directly attached to the lower surface of the mounting table 8 without providing legs 9 on the side walls of the mounting table 8. Even if the vacuum cleaner main body 1 is turned over, it is possible to prevent it from tipping over. Furthermore, the structure in which the exhaust passage 61 is formed between the mounting table 8 and the vacuum cleaner main body 1 can be used even if the upper part of the vacuum cleaner main body l does not have a hemispherical shape, or by providing legs 9 on the side wall of the mounting table 8. Placement stand 8
It can also be applied to those that have casters directly on the underside of the machine.

Furthermore, the means for regulating the rotation angle of the vacuum cleaner main body 1 can be implemented by using a device that does not make the upper part of the vacuum cleaner main body 1 spherical, or by not providing legs 9 on the side wall of the mounting table 8. It can also be applied to products that have casters installed directly on the bottom surface. The rotation angle can also be greater than 360 degrees.

According to the vacuum cleaner of claim 7, since the fitting portion between the mounting table and the vacuum cleaner body is approximately a perfect circle, the Tfil remover body rotates left and right with a minimum radius, and the direction of the vacuum cleaner body can be changed. It becomes extremely simple.

According to the vacuum cleaner according to claims 8 and 9, when the suction hose attached to the vacuum cleaner body is pulled from side to side, the legs protruding outward from the mounting base function as support rods, and the vacuum cleaner body It can prevent this from happening again.

In terms of the vacuum cleaners in S# requirements 10 and 11, the rotation of the vacuum cleaner body is regulated and the vacuum cleaner body does not rotate freely in one direction on the mounting table, so the power cord cannot be placed on the mounting table. Prevents it from becoming entangled in the mounting stand.

According to the vacuum cleaner according to claims 12 and 13, a heavy electric blower and a cord reel are provided at the bottom of the vacuum cleaner body,
Since the center of gravity of the vacuum cleaner body is moved closer to the surface to be cleaned, it is possible to prevent the vacuum cleaner body from flipping over.

According to the vacuum cleaner according to claims 14, 15, and 16, since the upper part of the vacuum cleaner body is hemispherical, the suction hose can be connected with the vacuum cleaner body in the circumferential direction of the F6# machine body with the minimum rotation radius. It can be rotated. Furthermore, according to the vacuum cleaner of claim 16, the knob concave part of the parts storage lid also serves as the knob concave part of the handle, thereby reducing the number of concave parts on the upper surface of the vacuum cleaner body, so that the vacuum cleaner body has a round shape. There is no harm to it.

According to the vacuum cleaner according to claims 17 and 18, the vacuum cleaner body can be easily moved in the mounting table so that its axis of rotation is substantially vertical, without causing the vacuum cleaner main body to shift from side to side on the mounting table. It can rotate.

According to the vacuum cleaner of claim 19, even if the suction hose attached to the hemispherical portion of the vacuum cleaner body is pulled from side to side, the tensile force acts mostly in the direction of rotating the vacuum cleaner body in the circumferential direction. To become.

According to the vacuum cleaner of Claims 20, 21, 22, and 23, the vacuum cleaner body is formed from the upper case and the lower case, so that it is possible to easily create a vacuum cleaner body in which only the upper part is hemispherical. Can be done.

According to the vacuum cleaner of the twenty-fourth aspect, since the upper case is covered with the lower case, even if dirt adhering to the upper case falls, it will not enter the mounting table. It is possible to prevent dirt from entering the mounting table and obstructing the rotation of the vacuum cleaner body.

According to the vacuum cleaner of claims 25, 26, and 27, since the lower surface of the leg portion is bowl-shaped, the vacuum cleaner body can be moved smoothly over a protrusion such as a threshold. In addition, the curved surfaces of the legs allow the legs to smoothly slide around obstacles even if they hit them, and prevent the power cord from getting caught in the legs. .

According to the vacuum cleaner of Claims 28, 29, 30, and 31, the mounting table functions as a noise-muffling tube with a long exhaust passage,
Since the exhaust flow is dispersed and exhausted at low speed, the noise generated by the rotation of the electric blower can be reduced. Moreover, the exhaust flow flowing from the bottom of the vacuum cleaner body toward the mounting base increases the pressure in the exhaust passage between the vacuum cleaner body and the mounting base, causing the vacuum cleaner body to float. The rotational force for rotating the main body can be reduced.

According to the vacuum cleaner of claim 32, even if the vacuum cleaner has a structure in which the exhaust port is provided on the side surface of the vacuum cleaner body, the exhaust air from the exhaust port rarely hits the user directly during cleaning, making it easier to use. Everywhere is good.
