Abstract

PURPOSE:To contain a hose in a small way, and to facilitate carrying it by connecting a freely bendable extension hose to the tip of a suction hose connected to a dust collection chamber, and connecting a hard extension tube to the tip part of this extension hose so as to be freely containable in the extension hose. CONSTITUTION:In the vacuum cleaner main body 1 which contains a motor-driven air blower, and also, is provided with a dust collection chamber 2 in the upper part, a suction hose 3 whose one end is connected to the dust collection chamber 2 is provided so as to be freely rotatable, and the other end of this suction hose 3 is connected to a connecting cylinder 5 for communicating with a suction port 4 so as to be freely attachable and detachable through an end tube 6. Usually, this cleaner is used in a state that the suction hose 3 is connected to the connecting cylinder 5 in such a way. On the other hand, in the case of cleaning a ceiling, a clearance of the reverse side of furniture, etc., the suction hose 3 is detached from the connecting cylinder 5, a connecting tube 12 of an extension hose 8 of a bellows structure is connected to the end tube 6, and also, a hard extension tube 9 contained in the extension hose 8 is handled so as to draw it out, and cleaning is executed by suction force for working on a brush 16 of the tip of the extension tube 9.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner having an extension tube and an extension hose.

[0002]

2. Description of the Related Art As a conventional technique of the present invention, Japanese Patent Laid-Open No.
As shown in Japanese Patent No. 189330, a hose connected to a cleaner body is detachably attached to a floor nozzle, and the hose can be removed from the floor nozzle when cleaning the ceiling or cleaning the bed. I removed it and attached it to the extension pipe for cleaning.

[0003]

However, in the above-mentioned prior art, since the extension pipe is made of a hard pipe, the bent portion is only the hose portion connected to the cleaner body, and the bottom portion of the bed. There was an inconvenience that it was difficult to clean the gap behind the chest and chest. It is an object of the present invention to eliminate such inconvenience and provide a convenient electric vacuum cleaner.

[0004]

The electric vacuum cleaner of the present invention comprises:
A cleaner body, a suction hose connected to the dust collecting chamber of the cleaner body, a bendable extension hose connected to the tip of the suction hose, and an extension hose extending from the tip of the extension hose. And a hard extension tube that is slidably inserted into the inside of the.

Further, in the vacuum cleaner of the present invention, a spiral reinforcing member is provided inside the extension hose along an inner wall of the extension hose, and an arcuate portion is provided at an end of the extension tube on the extension hose side. It is characterized by being shaped.

Further, the vacuum cleaner according to the present invention is characterized in that a brush is installed along the opening edge of the end portion of the extension pipe protruding outside the extension hose.

[0007]

According to the electric vacuum cleaner of the present invention, since the bendable extension hose is connected to the tip end of the suction hose, the length of the bendable portion is increased and the degree of freedom is increased. Also, since the extension pipe is stored inside the extension hose, it can be stored compactly. Furthermore, since the arcuate portion is formed at the end of the extension pipe on the extension hose side, the end of the extension pipe can be smoothly inserted without being caught in the spiral reinforcing member provided along the inner surface of the extension hose. It

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. Reference numeral 1 is a main body of an electric vacuum cleaner in which an electric blower (not shown) is built in and a dust collecting chamber 2 is provided on an upper portion thereof. Reference numeral 3 denotes a suction hose whose one end is connected to the dust collection chamber 2, and the other end is detachably connected to a connection cylinder 5 communicating with the suction port 4 via an end pipe 6. Reference numeral 7 denotes a handle provided on the cleaner body 1 for performing normal cleaning with this handle.

2 to 4 are sectional views showing the relationship between the extension hose 8 and the extension pipe 9, and FIG. 2 shows the extension hose 8 in a contracted state in which the projection 10 of the extension pipe 9 is located inside the extension hose 8. It is stored until it comes into contact with the holding tube 11 provided at one end. 1
Reference numeral 2 denotes a connecting pipe provided at the other end of the extension hose 8 and is detachably attached to the end cylinder 6. 3 shows a state in which only the extension hose 8 is extended, and FIG.
It is shown in a stretched state.

FIG. 5 shows a state in which the end pipe 6 of the suction hose 3 is removed from the connecting cylinder 5, and the suction hose 3 is rotated to direct the end pipe 6 upward. FIG. 6 shows a state in which the suction hose 3 and the extension hose 8 are connected via the end pipe 6 and the connection pipe 12, and the extension pipe 9 is further drawn out. FIG. 7 shows a state in which the extension tube 9 is being accommodated in the extension hose 8.
Since the arcuate portion 14 is formed on the storage-side end portion 13 of the extension pipe 9 as shown in an enlarged view, it is possible to catch on the spiral reinforcing member 15 provided along the inner surface of the extension hose 8. It will be smoothly stored in the extension hose 8. Reference numeral 16 is a brush that is planted at the opening edge of the extension tube 9.

Since this embodiment is configured as described above, during normal cleaning, the cleaning operation is performed in the state shown in FIG. 1, and when cleaning the ceiling, under the bed, or the gap on the back side of furniture, etc. Clean in the state shown in FIG. in this case,
Since the extension hose is bendable, it can be bent in all directions, and is easy to use, especially for cleaning gaps in narrow places.

[0013]

According to the present invention, since the hard extension pipe is housed in the bendable extension hose, the extension hose can be stored small in the housed state and the extension hose does not bend, so that it is easy to carry and hold. In addition, since the extension hose itself is bendable, it can be bent in any direction during cleaning to facilitate cleaning. Further, since the arcuate portion provided on the extension pipe does not catch on the spiral reinforcing member of the extension hose, the extension pipe can be smoothly stored in the extension hose.
