Note that this extension pipe 37 is not an essential component.

The suction port body 38 sucks dust from the floor surface by the negative pressure generated by driving the electric blower 15 . In this embodiment, the suction port body 38 is, for example, a floor brush that is placed on the floor and moved on the floor. The suction port body 38 has a case body 63 . The suction port body 38 also has a connection pipe 64 connected to the distal end side of the extension pipe 37 . This inlet body 38 may comprise a rotating cleaning body. Note that the suction port body 38 is not an essential component.

Next, the cleaning operation according to the embodiment will be described.

Briefly, the user connects the extension pipe 37 and the suction port body 38 to the tip of the hose body 31 connected to the cleaner main body 13 by the connecting body 32, and puts the suction port body 38 on the floor surface. The electric blower 15 is driven by holding the holding portion 61 and operating the setting button 20 . Then, the vacuum cleaner main body 13 is pulled by the air passage body 22 and moved to an appropriate position, and the suction port body 38 is repeatedly moved back and forth on the floor surface to utilize the negative pressure generated by driving the electric blower 15. Then, the dust on the floor surface is sucked together with the air from the suction port of the suction port body 38 .

At this time, the cleaner main body 13 can be used regardless of whether the main body portion 25 is in the normal position or the reverse position. For example, when the body portion 25 is in the normal position, the normal position support member 47 contacts the floor F with the normal position wheels 51 (FIG. 1), and the cleaner body 13 (main body portion 25) is moved together with the running wheels 24 on both sides. Stable running becomes possible by supporting the floor F at three points. At this time, the base end side of the hose body 31 is kept at a height with respect to the floor F by the normal position support member 47 and is not in contact with the floor F, and is not rubbed against the floor F. On the other hand, for example, when the body portion 25 is in the reverse position, the reverse position support member 48 contacts the floor F with the wheels 52 for reverse position (FIG. 2), and the running wheels 24 on both sides of the cleaner body 13 (the body portion 25 ) is supported on the floor F at three points, stable running becomes possible. At this time, the base end side of the hose body 31 is kept at a height with respect to the floor F by the reverse position support member 48, is out of contact with the floor F, and is not rubbed against the floor F.

In addition, for example, when changing direction, by swinging the main body 25 so as to turn it upside down about the rotation axis of the running wheel 24, the normal position and the reverse position are changed, and the vehicle runs on the spot. Reversal of direction is possible.

The dust-containing air sucked from the suction port of the suction port body 38 is sucked into the dust collection section 14 via the connection pipe 64, the extension pipe 37 and the hose body 31. The dust in the dust-containing air is separated and collected in the dust collection unit 14, and the air from which the dust is separated is sucked into the electric blower 15, cooled by the electric blower 15, and then exhausted from the cleaner main body 13. be. When the cleaning is finished, the user operates the setting button 20 to stop the electric blower 15. - 特許庁The dust collected by the dust collector 14 is discarded as necessary.

As described above, according to the present embodiment, one end of the hose body 31 is moved by contact with the floor F at the positions on the one swinging direction side and the other swinging direction side of the body portion 25 with respect to the connection body 32 . By providing a support member 33 that defines each swing end of the main body 25 at a position where the side does not contact the floor F, the height of the hose body 31 from the floor F is secured when the main body 25 swings. As a result, the lower portion of the hose body 31 is less likely to come into contact with the floor F, and the contact of the lower portion of the hose body 31 with the floor F pushes the base end of the hose body 31 upward, so that the connection body 32 (holding portion 41) is pushed upward. The base end of the hose body 31 is not easily deformed due to contact with the cleaner body 31, and the lower part of the base end side of the hose body 31 is not easily rubbed against the floor F when the cleaner body 13 runs, and the hose body 31 is not easily damaged.

In addition, by urging the support member 33 (normal position support member 47) against the connection body 32 by the urging member 34, the impact when the support member 33 (normal position support member 47) contacts the floor F is reduced. Since the force can be relieved by the biasing member 34, the user can swing and turn the body portion 25 of the cleaner body 13 without hesitation.

Further, since the support member 33 is provided with wheels 49 contacting the floor F, the cleaner main body 13 is movably supported by the wheels 49 together with the running wheels 24, thereby improving the running stability. Moreover, the normal position support member 47 is rotatably axially supported with respect to the connection body 32 (main body gripping portion 35), and is attached by the biasing member 34 in the direction of protruding from the connection body 32 (main body gripping portion 35). By applying force, the normal position wheel 51 maintains an appropriate contact pressure with the floor F, and the cleaner main body 13 can run smoothly.

By providing the connecting body 32 with the body gripping portion 35 to be gripped, the user can grip the body gripping portion 35 to lift the cleaner body 13 .

Further, by providing the main body gripping portion 35 along the traveling direction of the running wheels 24 of the cleaner main body 13, for example, when the cleaner main body 13 is erected with the front portion (air passage body 22 side) facing upward, The cleaner main body 13 can be easily lifted by the main body gripping part 35, and the space formed between the connecting body 32 and the floor F by the support member 33 can be effectively used, so that the main body gripping part 35 can be arranged in a space-saving manner.

Moreover, by inclining the end (front connecting portion 56) of the main body gripping portion 35 on the side of the hose body 31 in the direction toward the center of the hose body 31, for example, a position where the main body gripping portion 35 is on the lower side, the main In the embodiment, in the normal position, the end portion (front connecting portion 56) of the body grip portion 35 facing the floor F on the side of the hose body 31 is against unevenness on the floor F and small obstacles O (FIG. 1). It acts as a so-called sled, and it is possible to easily get over them and allow the cleaner body 13 to run smoothly. Furthermore, since the main body gripping portion 35 as a whole is inclined toward the front in a direction approaching the center of the hose body 31, it is possible to more easily overcome irregularities on the floor F and small obstacles.

In the above embodiment, instead of the normal position support member 47 of the support member 33, the reverse position support member 48 may be provided rotatably with respect to the connection body 32, or the normal position support member 47 and the reverse position support member 48 may be provided. Each of the position support members 48 may be provided rotatably with respect to the connector 32 . In this case, it is preferable that the reverse position support member 48 is also biased by the biasing member 34 .

Further, the main body gripping portion 35 may be provided at the lower portion of the connecting body 32 when the main body portion 25 is in the reversed position and the upper portion of the connecting body 32 when the main body portion 25 is in the normal position. A body gripping portion 35 positioned below the connecting body 32 with the body 25 in the normal position and a body gripping portion 35 positioned below the connecting body 32 with the body 25 in the reversed position may be provided. That is, the main body gripping portion 35 may be provided on the connector 32 at each of the one swing direction side (normal position side) and the other swing direction side (reverse position side) of the main body portion 25 .

Furthermore, the support member 33 itself may be configured to be made of an elastic material. In this case, even if the biasing member 34 is not used, the impact when the support member 33 comes into contact with the floor F can be reduced, so that the user can swing the main body 25 of the cleaner body 13 without hesitation. can be inverted.
