It is connected to the rear end. The dust collection hose 9 communicates with the dust collection chamber 6 of the cleaner body 2. The second pipe 11 accommodates a part of the operation pipe 3 provided with the handle portion 10 at the rear portion and has an attachment recess 12.

  Then, when the attachment recess 12 of the second pipe 11 is inserted into the connection opening 13 of the cleaner body 2 and engaged with the engagement protrusion (not shown), the engagement protrusion is moved by the lock mechanism (not shown). The second pipe 11, which is locked to 12 and accommodates a part of the operation pipe 3 inside, is attached to almost the entire area of the cleaner body 2 in the longitudinal direction. When the tip of the second pipe 11 is inserted into the connection opening 13 of the cleaner body 2, the tip of the second pipe 11 is sealed at the back. The lock of the engaging protrusion is released by pulling a release lever 15 provided on the upper surface of the handle 8 of the cleaner body 2.

  The operation pipe 3 includes a second pipe 11 and a small-diameter pipe 16 that is a third pipe inserted into the second pipe 11, and the small-diameter pipe 16 and the operation pipe 3 are inside the second pipe 11. Communicate. The second pipe 11 expands and contracts when the operation pipe 3 slides and moves within the second pipe 11, and is supported on the sliding coupling body 17 of the second pipe 11 by a spring 22 that is an elastic body. When the expansion / contraction operation button 18 provided is pressed, the second pipe 11 can be slid. When the expansion / contraction operation button 18 is released, the second pipe 11 is locked at that position. Yes.

  Reference numeral 23 denotes a closed body made of an elastic body provided so as to seal the communication portion 24 to the communication portion 24 of the small-diameter pipe 16 and the operation pipe 3 as a third pipe, and is adhered to the inner peripheral wall surface of the operation pipe 3. The inner peripheral tip of the closing body 23 is pressed against the outer peripheral wall surface of the small-diameter pipe 16 to prevent dust leakage and air leakage at the communication portion between the small-diameter pipe 16 and the operation pipe 3.

  The specific material of the closing body 23 made of an elastic body is composed of a rubber material such as natural rubber or urethane rubber, or a resin material having elasticity such as an elastomer.

  The portion of the sliding joint 17 of the second pipe 11 is exposed to the outside from the connection opening 13 of the cleaner body 2 when the second pipe 11 and the operation pipe 3 are attached to the cleaner body 2. . Therefore, the expansion / contraction operation button 18 provided on the sliding coupling body 17 is exposed to the front side of the cleaner body 2 as a part of the outline of the cleaner body 2.

  Further, the small-diameter pipe 16 is further expanded and contracted by sliding in the second pipe 11. Then, when the button 20 provided on the sliding connecting portion 19 is pressed, the small diameter pipe 16 can be slid and when the button 20 is released, the small diameter pipe 16 is locked at that position.

The suction port body 1 communicates with the dust collecting chamber 6 via the rotary tube 4 and the connection portion 5. However, in the state where the vacuum cleaner body 2 is erected, the communication is blocked, although not particularly shown. It has a structure. Further, as described above, the tip of the second pipe 11 attached to the cleaner body 2 is sealed at the back. Therefore, the suction from the tip of the small-diameter pipe 16 communicating with the operation pipe 3 and the second pipe 11 is performed with the second pipe 11 placed in the cleaner body 2 in the state where the cleaner body 2 is upright.
It can be used by removing it from.

  A power switch (operation switch) 21 for the electric blower 7 is provided on the upper portion of the cleaner body 2.

  About the vacuum cleaner in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, as shown in FIG. 2, the expansion / contraction operation button 18 is pushed to extend the operation pipe 3 housed in the second pipe 11. When the power switch 21 is turned on, the electric blower 7 is driven and the air in the dust collecting chamber 6 is sucked by the electric blower 7. By this suction, the dust collection chamber 6 becomes negative pressure, and this negative pressure acts on the rotary tube 4 and the suction chamber of the suction port body 1, and dust is sucked together with air from the suction opening of the suction chamber.

  Air and dust sucked into the suction chamber are sucked into the dust collecting chamber 6 of the cleaner body 2 through the rotary tube 4, and the dust is collected by the dust collecting filter F. The dust collection method may be a cyclone method without the dust collection filter F.

  Here, as shown in FIG. 1, a part of the operation pipe 3 is accommodated in the second pipe 11 that extends and contracts from the other end of the operation pipe 3, so that the cleaner pipe 2 can be operated by the operation pipe 3. The height of the storage when the second pipe 11 storing 3 is installed and the stand is stored on the floor surface can be lowered, and the vacuum cleaner can be stored compactly in the corner of the room without taking up space It is.

  In the case where the second pipe 11 is stored inside the operation pipe 3, a space for storing the second pipe 11 is required inside the operation pipe 3, so that the entire length of the operation pipe 3 is increased and the operation pipe 3 is shortened. When this occurs, the length protruding from the cleaner body 2 becomes longer, and the storage height from the floor surface where the operation pipe 3 is retracted and stored in the cleaner body 2 is increased. .

  Further, the sliding coupling body 17 portion of the second pipe 11 is exposed to the outside from the connection opening 13 of the cleaner body 2 when the operation pipe 3 is attached to the cleaner body 2 (the telescopic operation button 18 is cleaned). And the telescopic operation button 18 is exposed to the outer shell of the main body and stored in the main body 2 of the cleaner, so that the second pipe 11 is stored in the main body 2 of the cleaner. Since the telescopic operation button 18 provided on the pipe 11 is exposed to the outer shell of the main body, the telescopic operation button is simultaneously held while holding the handle 10 of the operation pipe 3 with one hand and holding the vacuum cleaner main body 2 side with the other hand. 8 can be operated, the operation pipe 3 can be expanded and contracted from the cleaner body 2 with one touch (one operation).

And when cleaning the floor surface by the suction inlet 1, as shown in FIG. 2, if the vacuum cleaner main body 2 is moved back and forth by holding the handle portion 10 of the operation pipe 3, the floor surface and the like are cleaned. Can be done. (At this time, the tip of the second pipe 11 attached to the cleaner body 2 is sealed.)
As shown in FIG. 4, when cleaning is performed by removing the second pipe 11 in which the operation pipe 3 is stored from the cleaner body 2, the cleaner body 2 is erected (the cleaner body 2 is erected). In this state, the communication with the dust collecting chamber 6 is cut off.) The lock of the engaging protrusion is released by pulling the release lever 15 provided on the upper portion of the cleaner body 2, and the operation pipe 3 is stored. By removing the second pipe 11 from the cleaner body 2, the air and dust sucked from the tip of the small-diameter pipe 16 are removed from the cleaner body 2 via the second pipe 11, the operation pipe 3 and the dust collecting hose 9. It is sucked into the dust collection chamber 6.

  Here, by providing a closing body 23 that seals the communication portion 24 in the communication portion 24 of the small-diameter pipe 16 and the operation pipe 3 that is the third pipe, it is possible to prevent spillage of dust from the communication portion 24 and the communication portion. The air leakage from 24 can be eliminated and the reduction of the suction force can be prevented.

  Further, since the closing body 23 is made of a rubber material such as natural rubber or urethane rubber or a resin material having elasticity such as an elastomer, the sealing portion 23 is secured and the operation pipe 3 and the third pipe are used. The sliding operability with a certain small diameter pipe 16 can be ensured.

  Furthermore, by providing the closing body 23 by adhering to the inner peripheral wall surface of the communication portion 24 of the operation pipe 3, the closing body 23 can be configured at low cost and easily assembled.

  In addition, it has a second pipe 11 that extends and contracts from the other end of the operation pipe 3, and further has a small diameter pipe 16 that is a third pipe that extends and contracts from the other end of the second pipe 11. By connecting and holding the small-diameter pipe 16 and the operation pipe 3 inside the second pipe 11, the second pipe 11 is removed from the cleaner body 2, and the operation pipe 3, the second pipe 11, and the small-diameter pipe 16 are connected. When the pipes are stretched, the flow of dust sucked through the pipe parts can be made smooth, and the ends of the pipe parts can be securely held to ensure the strength.

  In particular, the end of the small diameter pipe 16 and the end of the operation pipe 3 are communicated and held inside the second pipe 11 so that the total length of the pipe portion when the operation pipe 3, the second pipe 11, and the small diameter pipe 16 are extended. The strength of the can be improved.

  When the small-diameter pipe 16 and the operation pipe 3 are configured not to communicate with each other inside the second pipe 11, the flow path through which dust is sucked from the relatively small-diameter small-diameter pipe 16 into the large-diameter second pipe 11. After that, since the dust is sucked into the operation pipe 3 having a diameter smaller than that of the second pipe 11 from the second pipe 11 having a larger diameter, the smooth flow of the dust is prevented, This causes a problem that dust accumulates without being sucked into the second pipe 11 due to clogging or the like.

  In addition, since the small-diameter pipe 16 that is the third pipe is accommodated in the operation pipe 3, each pipe portion when the second pipe 11 that accommodates the operation pipe 3 is pulled out and extended from the cleaner body 2 is sucked. It is possible to prevent the dust from being caught or clogged by smoothing the flow of the dust.

  The flow path through which the dust is sucked is configured such that the dust is sucked into the operation pipe 3 having a diameter larger than that of the small-diameter pipe 16 from the relatively small-diameter pipe 16. It can prevent catching and clogging. On the contrary, when the operation pipe 3 is stored in the small-diameter pipe 16, the end face of the operation pipe 3 stands in a reverse step with respect to the flow direction in which the dust is sucked in the flow path for sucking the dust. Thus, the smooth flow of dust is hindered, causing problems such as dust catching and clogging.

  Further, by providing a small-diameter pipe 16 that is a third pipe that extends and retracts from the other end of the second pipe 11, the second pipe 11 is removed from the cleaner body 2, and the operation pipe 3 and the second pipe are removed. In this way, the entire length of the pipe portion when the small-diameter pipe 16 is extended can be secured long.

And the air attracted | sucked by the electric blower 7 passes through the motor (not shown) of the electric blower 7, and cools this motor. The air that has cooled the motor is exhausted from an exhaust hole (not shown) provided in the cleaner body 2 through an electric chamber (not shown).

  In the present embodiment, as shown in FIG. 5, instead of the closing body 23 in the first embodiment, a raised cloth 30 having air permeability is connected to the small-diameter pipe 16 that is the third pipe and the operation pipe 3. The unit 24 is provided. The brushed cloth 30 is provided by being bonded to the inner peripheral wall surface of the operation pipe 3, and the inner peripheral tip of the brushed cloth 30 is pressed against the outer peripheral wall surface of the small diameter pipe 16 and serves as a communication portion between the small diameter pipe 16 and the operation pipe 3. Prevents the leakage of trash such as coarse trash excluding fine dust.

  By providing a raised fabric 30 having air permeability instead of the closed body 23 that seals the gap in the communicating portion 24 between the third pipe and the operation pipe 3, the raised fabric 30 provided in the communicating portion 24 is connected to the communicating portion 24. It is possible to prevent the spilling of dust and to collect the dust accumulated in the communicating portion 24 in an attempt to spill again by the suction air passing through the raised cloth 30.

  Further, the raised cloth 30 is brought into contact (pressure contact) with the small-diameter pipe 16 which is the third pipe, thereby ensuring the sliding operability between the operation pipe 3 and the small-diameter pipe 16 and wear due to repeated sliding operations. Loss and durability can be secured.

  In the present embodiment, the raised fabric 30 having air permeability is composed of the hair 32 planted on the base material 31, and the hair 32 is densely planted on the base material 31 to prevent dust leakage up to very fine dust. In addition to being able to prevent this, air leakage from the communication portion 24 can be suppressed to some extent, and a reduction in suction force can be relatively improved.

  On the contrary, if the hair 32 is roughly planted on the base material 31, the dust accumulated in the communication portion 24 in a spilling manner can be sucked relatively strongly.

  Further, by providing the raised cloth 30 by adhering to the inner peripheral wall surface of the communication portion 24 of the operation pipe 3, the raised cloth 30 can be configured at low cost and easily assembled.

  In the first embodiment, the closing body 23 is bonded to the inner peripheral wall surface of the operation pipe 3, but in the present embodiment, the closing body 23 is attached to the outer periphery of the small-diameter pipe 16 as shown in FIG. Adhering to the wall surface, the outer peripheral tip of the closing body 23 is pressed against the inner peripheral wall surface of the operation pipe 3.

  Similarly, in the second embodiment, the brushed cloth 30 is provided by being bonded to the inner peripheral wall surface of the operation pipe 3, and the inner peripheral tip of the brushed cloth 30 is pressed against the outer peripheral wall surface of the small-diameter pipe 16. However, as shown in FIG. 7, the raised cloth 30 may be provided by being bonded to the outer peripheral wall surface of the small-diameter pipe 16, and the outer peripheral tip may be pressed against the inner peripheral wall surface of the operation pipe 3.

As a result, the closing body 23 or the raised cloth 30 can be constructed at a low cost, and the bonding workability of the closing body 23 or the raised cloth 30 is improved by bonding the closing body 23 or the raised cloth 30 to the outer peripheral wall surface of the small-diameter pipe 16, thereby further improving the assembly.
