The lever member 40 protrudes downward when the filter 33 is attached and detached, and rotates and retracts upward when the filter 33 is attached. Thereby, the lever member 40 abuts on the bottom surface of the fitting portion 32a when the filter 33 is not attached, and the filter case 34 cannot be normally inserted into the fitting portion 32a.

  A lock member 36 made of a slide member that slides in a substantially circumferential direction is provided at the rear portion of the fitting portion 32 a of the container cover 32. FIG. 11 shows a rear view of the cyclone dust collecting portion 3 when the lock member 36 is viewed from the front. FIG. 12 is a cross-sectional view taken along the line DD in FIG. On the peripheral surface of the filter case 34, a step portion 34b is projected. The lock member 36 has a knob 36a protruding outward, and slides in sliding contact with the upper surface of the step portion 34b by operating the knob 36a.

  As shown in FIGS. 11 and 12, when the lock member 36 is disposed at the unlocked position away from the step portion 34b, the filter case 34 can be attached to and detached from the fitting portion 32a. As shown in FIGS. 13 and 14, when the lock member 36 slides and is disposed at the lock position where it engages with the stepped portion 34 b, the filter case 34 is held by the fitting portion 32 a.

  An inclined surface 36b is formed on the lower end of the lock member 36 on the side close to the step 34b. When the filter case 34 is inserted into the fitting portion 32a, the filter 33 is placed on the annular rib 32b (see FIG. 8) protruding from the bottom surface of the fitting portion 32a. At this time, the lock member 36 in the unlocked position is arranged such that the sliding contact surface with the step 34b is higher than the step 34b.

  Since the front end of the lock member 36 is formed of the inclined surface 36b, the lock member 36 can be easily slid to the lock position while the filter case 34 is pushed down. Thereby, the lock member 36 can maintain the filter case 34 in a state where the filter case 34 is lowered against the elastic force of the filter 33 at the lock position, and the rib 32 b and the filter 33 can be brought into close contact with each other.

  Moreover, the step part 34b is formed in the inclined surface which the front goes up, and the filter case 34 advances by the lock member 36 sliding and being arrange | positioned to a lock position. FIG. 15 shows a detailed view of part B of FIG. A convex portion 34 c is formed on the front surface of the filter case 34. On the front side of the fitting portion 32a, a concave portion 32c made of a through hole facing the convex portion 34c is formed.

  When the lock member 36 moves from the unlocked position to the locked position, the filter case 34 moves forward, and the convex portion 34c is fitted into the concave portion 32c as shown in FIG. Thereby, the front part of the filter case 34 can be maintained in the lowered state, and the rib 32b and the filter 33 can be more closely attached. A rib that is inclined so that the left side in FIG. 14 is rearward may be erected on the stepped portion 34b, and the filter member 34 may slide forward when the lock member 36 slides.

  The upper part of the convex part 34c is an inclined surface whose vertical section is formed in an arc shape. For this reason, the convex part 34c distribute | arranged above the recessed part 32c with the elastic force of the filter 33 can be easily fitted to the recessed part 32c.

  Further, a rib (not shown) is provided on the back surface of the storage chamber 4g (see FIG. 3) of the main body portion 4 so that the knob 36a of the lock member 36 in the unlocked position is in contact with the back surface. Thereby, when the filter case 34 is not attached, the storage of the cyclone dust collecting portion 3 is prevented by the contact between the tab 36a of the lock member 36 and the rib. Therefore, forgetting to attach the filter case 34 can be prevented.

  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 through the air flow path 4a and flows into the dust collecting container 31 of the cyclone dust collecting unit 3 through the air inlet 31a.

  The air flowing into the dust collecting container 31 from the air inlet 31a becomes a swirling airflow in the dust collecting container 31, and the dust is separated and accumulated in the dust collecting container 31 by centrifugal force. The air from which dust has been removed in the dust collecting container 31 ascends the inner cylinder 35 through the exhaust port 35a as indicated by an arrow A (see FIG. 8), and fine dust is collected by the filter 33. The air in which dust is collected by the filter 33 flows out from the air outlet 34a, and is exhausted from an exhaust port (not shown) through the room where the electric blower 2 is disposed through the communication hole. 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 portion 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 cyclone dust collecting section 3 through the air flow path 4b.

  Thereby, as shown in FIG. 18, 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 or the like can be easily cleaned as shown in FIG.

  When dust accumulates in the dust collecting container 31, the handle 3b is held and the cyclone dust collecting unit 3 is taken out from the storage chamber 4g. The container cover 32 and the dust collecting container 31 are separated, and the dust accumulated in the dust collecting container 31 is discarded. Further, the lock member 36 is disposed at the unlocked position, the filter case 34 is detached from the container cover 32, and the filter 33 taken out from the filter case 34 is cleaned. Thereby, the fall of the dust collecting force by the clogging of the filter 33 can be recovered.

  According to this embodiment, since the cyclone dust collection part 3 was accommodated in the storage chamber 4g, the aesthetics of the vertical vacuum cleaner 1 are improved without the cyclone dust collection part 3 being exposed. In addition, the upper wall of the storage chamber 4g having the communication hole and the upper surface of the cyclone dust collecting unit 3 having the air outlet 34a are inclined surfaces that are lowered rearward. For this reason, the cyclone dust collecting part 3 can be attached and detached without causing sliding friction between them, and these can be brought into close contact with each other when the storage is completed. Therefore, the cyclone dust collection part 3 can be attached or detached easily.

  In addition, since the lock member 36 that keeps the filter case 34 lowered against the elastic force of the filter 33 is provided at the rear of the container cover 32, the filter 33 and the container cover 32 can be easily brought into close contact with each other. Can be prevented from flowing out. Thereby, when cleaning the filter 33, the filter case 34 can be attached or detached easily, and the convenience of the vertical vacuum cleaner 1 is improved. Further, the rear portion of the filter case 34 can be lowered by the lock member 36 so that the cyclone dust collecting portion 3 can be easily inserted into the storage chamber, and the lock member 36 provided at the rear portion is not exposed to prevent the appearance from deteriorating. Can do.
