Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a vacuum cleaner, and particularly to a vacuum cleaner suitable for improving the running performance of the vacuum cleaner, the strength of the wheel attachment portion, and the storability of the attached suction port.

[Background of the invention]

In conventional vacuum cleaners, the axle bearing stand that supports the axle is made of plastic material and is provided separately from the vacuum cleaner body, and the attached suction port can be held on this. A rib was provided, and the inner diameter of this circular rib was matched to the fitting diameter of the attached suction port. With this type of configuration, space is required to store the attached suction port on the wheel bearing stand, and the wheel stand needs to be extended from the vacuum cleaner body, which reduces the mechanical strength of the wheel bearing stand itself. The problem is that the only way to reinforce it is to install ribs, and for reasons of strength, the storage position of the attached suction mouth is restricted, meaning that it cannot be extended from the main body of the vacuum cleaner. Furthermore, there is a drawback that if the attached suction port is accidentally pulled laterally while the Class I suction port is stored, there is a risk that the circular rib may be damaged. Furthermore, when storing the attached suction port, it is inserted while aiming at the inner diameter of the circular rib, so there is a drawback that it is difficult to fit.

[Purpose of the invention]

It is an object of the present invention to provide a vacuum cleaner which eliminates the following two drawbacks of the prior art, improves the strength of the wheel attachment portion, and improves running performance and storage of the suction port.

[Summary of the invention]

In the present invention, the axle bearing stand 5 is provided separately from the main body of the vacuum cleaner and extends out, and a circular groove with a bottom and having a depth below the axle axis is provided in the projecting part approximately on the axle axis. The diameter of the groove matches the fitting diameter of the attached suction port, and the circular groove serves as a reinforcement to improve the strength of the axle bearing base.Furthermore, if the strength is still insufficient, the side surface of the axle bearing base A reinforcing rib can be freely placed between the wheel cradle and the circular groove, and since this reinforcing rib is provided inside the wheel holder, it is not visible on the outside, so it is not a design problem. There is no need to worry about spoiling the aesthetic appearance. Also,
Since there is no circular rib on the top of the axle bearing stand, the area other than the groove can be made flat, so when storing the accessory nozzle, the fitting end of the accessory nozzle can be slid flat and guided into the groove. , the storage capacity of the attached mouthpiece has been improved.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. The vacuum cleaner main body 1 is composed of a main body case 2 having a built-in electric blower If& (not shown) in the upper part, and a dust collection case 3 having a built-in dust collector (not shown) in the lower part. The dust collection case 3 has casters 4 and an axle 5 for running, via a caster holder 6 and an axle holder 7, respectively. Here, the caster pedestal 6 and the wheel bearing pedestal 7 are constructed separately from the dust collection case 3, and are fixed with screws. The axle holder 7 is provided with cylindrical portions 8 at both ends to rotatably mount the wheel 5, and the axle 5 is attached to the wheel holder 7 by a snap fit. The cylindrical portion 8 of the axle bearing stand 7 is configured to protrude beyond the outer periphery of the dust collection case 3, and the protruding portion 9 has a circular groove 10 with a bottom and having a depth below the axis of the axle 7. is provided approximately on the axis of the axle 5, and the groove diameter of the circular groove 10 is set to match the fitting diameter of the attached suction ports such as the gap suction port 11 and the shelf side suction port 12. Furthermore, the inside of the wheel holder 7 has a reinforcing rib 15 that connects the side surface 13 of the circular groove 10 and the side surface 14 of the axle holder 7.

In the vacuum cleaner described above, forces are applied to the casters 4 and caster pedestal 6, as well as the axle 5 and axle pedestal 7, due to driving, accidental dropping, ftl'tt, etc.
However, in particular, the dust collection case 3 is used to store the attached suction port.
Since the configuration is made to protrude more, the strength of the axle bearing stand 7 becomes a problem, but in this embodiment, the circular groove 1O for storing the accessory suction ports such as the gap suction port 11 and the shelf side suction port 12 has a bottom. Moreover, since it is located on the axis of the axle 5, which receives the impact force first, and is formed integrally with the axle bearing pedestal 7, it serves as a reinforcement. In addition, if further reinforcement of the axle bearing stand 7 is required, since the circular groove lO has a depth below the axis of the axle 5, a reinforcing rib 15 having sufficient height for reinforcement can be inserted into a circular shape. Side surface 13 of groove lO
Since the reinforcing ribs 15 are not visible on the outside and can be effectively provided between the reinforcing ribs 15 and the side surface 14 of the axle bearing pedestal 7, they can be freely placed and added as needed.

Furthermore, the upper surface of the axle bearing stand 7 is set flat except for the circular groove 13, so that when storing the suction port,
It can be inserted into the circular groove 10 by sliding on the upper surface 16 of the fitting end r of the attached suction port.

That is, according to the present embodiment, the wheel bearing stand 7 is configured to extend out from the dust collection case 3 in order to accommodate the accessory suction ports such as the gap suction port 11 and the shelf side suction port 12, which poses a problem. The strength can be sufficiently ensured by the circular groove 10 and the reinforcing ribs 15, and the reinforcing ribs 15 can be added as necessary.
can be added in a free arrangement, which has the effect of improving the strength of the axle bearing stand. In addition, since it can be reinforced for strength, the axle bearing stand 7 can be configured to extend sufficiently from the dust collection case 3, so the position of the axle 5 can be shifted to the rear of the vacuum cleaner body 1, making it difficult to fall over and providing stable running. This has the effect of improving running performance, that is, improving running performance. Furthermore, since the fitting end of the accessory suction port can be inserted into the circular groove 10 by sliding on the upper surface 16 of the axle bearing base 7, there is an effect that the accessory suction port can be easily stored.

〔Effect of the invention〕

According to the present invention, in the case where the axle mounting portion of the wheel holder protrudes from the main body of the vacuum cleaner and the attached suction port can be stored in the protruding portion, the wheel holder can be sufficiently secured. Since the axle mounting part of the vacuum cleaner body is sufficiently protruded, it has the effect of improving the running stability of the vacuum cleaner body, and since the top surface of the wheel holder is flat except for the groove, the attached suction It can be stored by sliding it,
Furthermore, since the wheel attachment portion can be sufficiently extended from the vacuum cleaner main body, a sufficient space can be secured for the storage portion, so that the vacuum cleaner can be easily stored.
