Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction hose of a vacuum cleaner which is detachably attached to a tip of a vacuum cleaner side hose for use.

[0002]

2. Description of the Related Art In FIG. 6, a vacuum cleaner 1 having a plurality of wheels 2 sucks air containing dust from a suction connection portion 3 and removes the dust through a filter (not shown), and then from an exhaust port (not shown). Air can be discharged.

A flexible bellows hose 5 is attached to the suction connecting portion 3 via the connecting portion 5a. Further, the main hose 6 is attached via a connecting portion 5b provided at the tip of the bellows hose 5. The main hose 6 is made of metal or synthetic resin for the convenience of handling and has an axis Z.
It has an inflexible structure that is straight to zero. Further, at the tip of the main hose 6, for example, a connection portion (insertion port) 6a shown in FIG. 7 corresponding to the connection portion 7a of the suction tool 7 is provided.
6h is a through hole forming an air flow path.

In the assembled state shown in FIG. 6, while holding the main hose 6, the suction tool 7 is moved on the floor or the like. Then, the air containing dust is sucked into the suction tool 7 and the main hose 6.
Through the (through hole 6h) and the bellows hose 5, the cleaner 1 is sucked to remove dust.

By the way, although the suction tool 7 is configured to efficiently clean a horizontal floor surface or the like, it is not suitable for cleaning a small gap 61 between furniture 60L and 60R shown in FIG. 8, for example. Thus, as shown in FIG. 7, an attachment 8 can be attached to the tip of the main hose 6 forming the cleaner-side hose (connecting portion 6a) in place of the suction tool 7.

The attachment 8 is in the form of a tip end cylindrical cylinder nozzle having a thick portion 8L having a connection portion (connection port) 8b and a detail 8S having a suction port 8a, and the suction port 8a and the connection portion (connection port). ) 8b is communicated with a suction through hole 8h forming an air flow path. Therefore, the axis Z0
If the attachment 8 of the axis Z1 attached to the tip of the main hose 6 (connecting portion 6a) is inserted between the furniture 60L and 60R while being fed in the direction of the axis Z1 (Z0), the above gap 6
The inside of 1 can be cleaned.

[0007]

However, the attachment 8 of the related art is not limited to the nozzle shape of the tip end iris cylinder shown in FIG. 7, but is formed of a hard synthetic resin, that is, an inflexible structure. Therefore, no matter how large the length L in the direction of the axis Z1 is, the wall surface 50 and the furniture 6 shown in FIG.
It is very difficult to suck (clean) the dust accumulated in the gaps 51L and 51R between the 0L and 60R. In particular, it is impossible to clean dust that has adhered to the wall surface 50 and the back surface 63 of the furniture 60L and 60R, that is, the upper and lower sides of the standing surface. Furthermore, as shown in FIG.
It is difficult to clean the dust accumulated on the upper surface 64 of the furniture 60L (60R) no matter how the angle is adjusted. That is, the attachment 8 of the related art has a low applicability to a curved portion, a narrow place, an upright surface, an upper surface, and the like, and it is impossible to clean those places.

An object of the present invention is to provide a suction hose for a vacuum cleaner, which has a wide applicability to curved portions, narrow places, upright surfaces, upper surfaces, etc. and can be cleaned with high efficiency.

[0009]

SUMMARY OF THE INVENTION According to the present invention, a base end has a connection port that can be directly or indirectly attached to or removed from the tip of a cleaner-side hose, and a suction port is provided on at least one of the tip and the peripheral surface. The hose body has a body-holding member mounted along the longitudinal direction of the hose body, and the hose body is made of a highly flexible material that can be easily bent and deformed. It is characterized in that it is formed of a material that can be bent and deformed by an external force and can retain the shape of itself and the hose body after the bending and deformation when the external force is removed after the bending and deformation.

In the invention of such a structure, the hose body is attached to the hose on the cleaner side by using the connection port provided at the base end portion of the hose body. Then, when an external force is applied to cause the hose body to be entirely curved and deformed, the posture maintaining member is also curved and deformed. If the external force is removed in this state, the posture maintaining member can retain the posture of the self and the hose body after being curved and deformed. Therefore, if this hose body is inserted, dust can be sucked from the suction port provided at the tip and / or the peripheral surface, so that the curved portion, the narrow place, the rising surface and the upper surface can be efficiently cleaned.

When cleaning the gap between the furniture and the wall surface shown in FIG. 7, the tip end side of the main body hose is slightly curved and deformed to the left (right) side in order to determine the directionality. When the main body hose is pushed in, the tip end hits the wall surface. That is, an external force is received from the wall surface. Therefore, if the main body hose is further pushed in, the main body hose can be inserted into the gap while being curvedly deformed, so that the back surface of the furniture or the like can be easily cleaned.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) In FIG.
The suction hose 10 of the cleaner is composed of a hose body 11 and a posture holding member 21, and is attachable to and removable from the cleaner-side hose 6 via the attachment 30, that is, indirectly.
