  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a vertical vacuum cleaner according to an embodiment. The vertical vacuum cleaner 1 includes a main body 4 that houses an electric blower 2 and a dust collector 3 (see FIG. 3 for both). A suction port body 5 having an air inlet facing the floor surface is provided below the main body portion 4, and the main body portion 4 can be tilted with respect to the suction port body 5.

  A detachable extension pipe 6 extends in the vertical direction above the main body 4 as will be described in detail later. A grip 8 that is gripped by the user is provided on the upper part of the extension pipe 6. A telescopic connection hose 7 is connected to one end of the extension pipe 6. The extension pipe 6 and the electric blower 2 in the main body 4 communicate with each other through the connection hose 7.

  2 and 3 show a front view and a side sectional view of the vertical vacuum cleaner 1, respectively. In the main body 4, a dust collection unit 3 is arranged below the electric blower 2 in communication. The suction port body 5 and the dust collecting part 3 communicate with each other through an air flow path 4 a provided in the main body part 4. The dust collection unit 3 has a dust collection container 3a and is of a cyclone type that separates dust by a swirling airflow. The front panel 4d of the main body 4 can be opened and closed by holding the handle 4e, and the dust collecting container 3a that collects dust can be attached and detached together with the front panel 4d.

  An air flow path 4 b that opens at the upper surface and communicates with the dust collection unit 3 is provided at the rear of the main body 4. A lower support portion 4c into which the lower end of the connection hose 7 is fitted is formed at the upper end of the air flow path 4b. The lower portion of the connection hose 7 is supported substantially vertically by the lower support portion 4c. The upper end of the connection hose 7 is fitted into an upper support portion 9 a formed on the movable portion 9 attached to the extension pipe 6. The movable portion is rotatably supported by the shaft portion 9b, and the upper portion of the connection hose 7 is supported substantially vertically by the upper support portion 9a. As will be described in detail later, the connection hose 7 is provided with a hooking portion 20 for hooking the power cord 14 (see FIG. 9).

  Between the electric blower 2 and the air flow path 4b, an extension pipe housing part 4f that opens the upper surface of the main body part 4 is provided. The extension pipe storage portion 4f stores the tip of the extension pipe 6, and the extension pipe 6 can be detached from the main body portion 4 as shown in FIG.

  The extension pipe 6 can be divided into a lower part 6a and an upper part 6b as shown in FIG. An air flow path 6d composed of a through hole is formed in the lower part 6a, and an extension pipe 6c is arranged in the air flow path 6d. When the extension pipe 6 is detached from the main body portion 4, the extension pipe 6 can be extended by pulling out the extension pipe 6 c from the tip of the extension pipe 6.

  An air flow path 6e formed of a through hole is formed in the upper portion 6b where the grip portion 8 is provided. The upper end of the air flow path 6 e and the upper support part 9 a of the movable part 9 are connected by an intermediate hose 10 inserted through the movable part 9. The intermediate hose 10 is made of a softer resin than the connection hose 7, is formed in a bellows, and has flexibility. Thereby, the intermediate hose 10 follows the movable part 9 which rotates with respect to the extension pipe 6, and the connection between the extension pipe 6 and the connection hose 7 can be maintained.

  In the vertical vacuum cleaner 1 having the above configuration, when the electric blower 2 is driven in a state where the extension pipe 6 is attached to the main body 4, air is sucked together with dust from the suction port of the suction port body 5. The air sucked from the intake port flows into the dust collecting part 3 through the air flow path 4a, and the dust is separated by the centrifugal force due to the turning. The separated dust accumulates in the dust collecting container 3a and is discarded by opening the front panel 4d. The air from which the dust is removed by the dust collecting unit 3 is exhausted from an exhaust port (not shown) through a room in which the electric blower 2 is disposed. Thereby, the floor surface is cleaned.

  At this time, the extension pipe 6 and the inner surface of the extension pipe storage portion 4f are sealed by packing (not shown), and no airflow flows between the extension pipe storage portion 4f and the air flow path 4b. Thereby, the work rate reduction of the vertical vacuum cleaner 1 is prevented.

  When the extension pipe 6 is detached from the main body 4 by operating the hook 11, the extension pipe 6c is pulled out from the tip of the extension pipe 6 as shown in FIG. When the electric blower 2 is driven, air is sucked together with dust from the tip of the extension pipe 6c. The air sucked from the extension pipe 6c flows through the air flow paths 6d and 6e, the intermediate hose 10 and the connection hose 7 of the extension pipe 6 and flows into the dust collecting section 3 through the air flow path 4b.

  As a result, as shown in FIG. 7, it is possible to easily clean the air conditioner, ceiling, furniture gap, and the like disposed above the room. Further, when the upper portion 6b of the extension pipe 6 is separated by the operation of the hook 12, the desk top can be easily cleaned as shown in FIG.

  FIG. 9 is a perspective view of the vertical vacuum cleaner 1 as seen from the back. An outlet 4g through which the power cord 14 is pulled out is provided at the top of the main body 4. The power cord 14 extending from the outlet 4g is hooked to a hooking portion 20 attached to the connection hose 7. Thereby, the usability deterioration by the power cord 14 hanging down and entangled with the suction inlet 5 during cleaning can be prevented.

  10, 11, and 12 show a perspective view of the latching portion 20 as seen from the back side, a perspective view as seen from the front side, and a bottom view. The latching portion 20 made of a resin molded product has flexibility and has an annular portion 21 that fits with the connection hose 7. The annular portion 21 is divided at one place, and can be bent at a fold line 21a separated from the divided place by about a half circumference.

  Further, the annular portion 21 is provided with hooks 22 and holes 23 at both ends in the circumferential direction facing each other by division. By inserting the connection hose 7 into the annular portion 20 and engaging the hook 22 with the hole portion 23, the connection hose 7 is sandwiched and the latching portion 20 is attached to the connection hose 7. The connecting hose 7 may be clamped by elasticity without dividing the annular portion 20.

  A groove portion 24 through which the power cord 14 is inserted and hung is provided at a position about 90 ° away from the fold line 21a. The front surface of the groove 24 is covered with a gap 25a by a front wall 25 extending from both side walls. When the power cord 14 is pressed against the gap 25a, the front wall 25 is elastically deformed, and the power cord 14 can be inserted into the groove 24.

  The upper portion of the gap 25a is narrower than the lower portion. For this reason, when the power cord 14 extending from below is pulled from below, it can be easily detached from the groove 24, but when it is pulled from above, it is not easily detached. Thereby, the power cord 14 is hard to come off during cleaning, and the convenience of the vertical vacuum cleaner 1 can be improved.

  A hook insertion portion 26 into which a hook 6f (see FIG. 3) provided on the extension pipe 6 is inserted is provided at a position about a half circumference away from the groove portion 24. The hook insertion part 26 is provided with a front wall 26 a that covers the upper part on the front side and a rib 26 b that protrudes from the annular part 21. When the vertical vacuum cleaner 1 is stored, the hook 6f is inserted into the hook insertion portion 26 as shown in FIG. The hook 20 is sandwiched between the front wall 26 a and the rib 26 b so that the connection hose 7 is held by the extension pipe 6.

  That is, the hook 6 f and the hook insertion portion 26 constitute a hose holding portion that holds the connection hose 7 without spreading when the vertical vacuum cleaner 1 is stored. Therefore, it is not necessary to separately provide a holding member in the connection hose 7, and the number of parts of the vertical vacuum cleaner 1 can be reduced. You may comprise a hose holding part by the hole provided in the extension pipe 6, and the hook provided in the latching | locking part 20. FIG.

  FIG. 14 shows a front view of the connection hose 7, and FIG. 15 shows a cross-sectional view of part A in FIG. 14. The connection hose 7 has a core wire 7a formed in a spiral shape, and a surface member 7b made of a resin molded product is supported by the core wire 7a. The connection hose 7 can be expanded and contracted by the elasticity of the core wire 7a.

  The surface member 7b has a spiral cylindrical surface 7c whose peripheral surface is flat in the axial direction, and the adjacent cylindrical surfaces 7c are connected by a connecting surface 7d. When the connection hose 7 is contracted, the connecting surface 7d is folded on the inner surface of the cylindrical surface 7c, and the adjacent cylindrical surfaces 7c approach each other and are stacked in the axial direction. Therefore, when the extension pipe 6 is attached to the main body 4, it can be slid up and down by sliding the latching portion 20 with the cylindrical surface 7 c with respect to the connection hose 7 arranged substantially vertically.

  When the connection hose 7 is pulled in the axial direction, the connecting surface 7d is pulled out from the inner surface side of the cylindrical surface 7c, the interval between the adjacent cylindrical surfaces 7c is widened, and the connection hose 7 is extended. Therefore, when the extension pipe 6 is detached from the main body 4, the connection hose 7 can be extended to easily clean the ceiling and the like. At this time, if the latching portion 20 is slid downward, the connection hose 7 can be greatly extended.

  In FIG. 15, an arrow B indicates the direction of airflow. Since the connecting surface 7d is folded downward, the connecting surface 7d is inclined so that the opening area on the downstream side is narrowed. For this reason, it is possible to suppress an increase in pressure loss due to the connecting surface 7d when cleaning is performed in a state where the extension pipe 6 is detached and a part of the connection hose 7 is contracted.

  According to this embodiment, since the hooking portion 20 of the power cord 14 is attached to the telescopic connection hose 7, the connection hose 7 extends when the extension pipe 6 is detached from the main body portion 4, so that the power cord 14 is removed. There is no need. For this reason, the extension pipe 6 can be easily detached and cleaned, and the convenience of the vertical vacuum cleaner 1 can be improved.

  Further, an annular portion 21 for holding the connection hose 7 is provided in the latching portion 20, and when the extension pipe 6 is attached to the main body portion 4, the connection hose 7 is contracted and is supported substantially vertically on the main body portion 4. Therefore, the latching part 20 can be easily moved up and down by sliding the annular part 21 of the latching part 20 and the connection hose 7. Therefore, the position of the latching portion 20 can be changed by attaching and detaching the extension pipe 6 so that the power cord 14 does not get in the way, and the convenience of the vertical vacuum cleaner 1 can be further improved.

  Further, when the extension pipe 6 is attached to the main body portion 4 and the connection hose 7 is contracted, the cylindrical surface 6c continuous in the axial direction is laminated, so that the annular portion 21 of the latching portion 20 and the cylindrical surface 7c of the connection hose 7 are laminated. Can be moved up and down more easily.

  Further, since the connecting hose 7 is connected to the spiral cylindrical surface 7c supported by the core wire 7a and the connecting hose 7 is contracted, the connecting hose 7 is folded to the inner surface of the cylindrical surface 7c. A sufficient thickness can be secured.

  Further, since the cylindrical surface 7c is reinforced by the folded connection surface 7d, the connection hose 7 is difficult to bend, and the latching portion 20 can be moved up and down more easily. In addition, it is possible to ensure a large inner diameter when the connection hose 7 is contracted. Thereby, when cleaning in a state where a part of the connection hose 7 is contracted, a large air flow area can be secured and a high suction force can be maintained.

  In addition, although the cylindrical surface 7c consists of a helical member, you may comprise by a some annular member and it may connect with a connection surface. Moreover, you may form the cylindrical surface 7c and the connection surface 7d by another member.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the vertical vacuum cleaner which can be attached or detached with respect to a main-body part with the extension pipe extended from the main-body part and having a holding part.
