By inserting, the dust collecting container 4 can be stored in a predetermined position.

  As shown in FIG. 2, the dust collecting container 4 has a communication port 12 communicating with the suction port 3 and a disposal opening 4 c for discarding accumulated dust on the opposite side of the communication port 12. It is composed of an accumulating portion 4a for accumulating sucked dust and a rear lid portion 4b.

  The lid 4b is formed from a filter 17 that is integrally formed with the frame 16. A seal packing 18 as a sealing means is provided on the entire periphery of the frame body 16 on the side of the disposal opening 4c. When the lid body portion 4b is closed, the frame body 16 is tightly sealed with the accumulation portion 4a. The lid portion 4b is attached to the accumulating portion 4a by two hinge portions 19 and 19 disposed on the lower side of the frame body 16 so as to be openable and closable, and the locking portion 20 and the lid provided above the accumulating portion 4a. It is comprised so that it can close | close so that locking is possible by the to-be-latched part 21 provided in the body part 4b.

  The filter 17 is a fine dust filter that has been pleated (processed into a cross-sectional wave shape) so that linearly extending peaks and troughs are alternately formed. The direction of the fold of the valley portion is formed so as to be in the vertical direction in a state where the dust collecting container 4 is placed on the dust collecting container storage portion 5 of the main body 1 in the entire filter.

  FIG. 3 is a diagram showing a configuration for attaching the dust removing body, and FIG. 4 is a diagram showing a longitudinal section of the dust collecting container. 3 and 4, a reinforcing portion 22 that reinforces the peak portion is formed integrally with the filter 17 at the peak portion of the filter 17, and dust removal described later is performed on the reinforcing portion 22 in a direction orthogonal to the peak portion. The protrusion 23 is integrally provided so that the body 24 can move slidably. The dust removing body 24 is fixed by being sandwiched by a cover member 25 so that the dust removing body 24 can be moved and fitted with a groove 26 that can be fitted to the projecting portion 23 on the upper side. It is attached by screw or claw fitting.

  The dust removing body 24 includes a main body portion 27, a base portion 28, and a contact portion 29 that contacts the reinforcing portion 22 of the filter 17. The main body 27 is made of a flexible and flexible material such as rubber, the base 28 and the contact portion 29 are formed of resin or the like, and the base 28 and the contact portion 29 are fitted with unevenness, bonded, and fixed with screws. , And combinations thereof, are fixed to the main body 27. Further, as shown in FIG. 5, the base 28 and the main body 27 are combined with each other at the hinge portion, and the filter 17 is moved by the spring 30 so as to be swingable in the direction perpendicular to the surface of the filter 17 between the hinge portions. You may comprise so that it may urge to the surface side.

  On the front side of the filter 17, a coarse dust prefilter 32 made of nylon or polyester and formed integrally with the cover body 31 is installed. Further, a sealing means is provided at the rear portion of the lid body portion 4 b of the dust collection container 4, that is, at the joint portion between the peripheral portion of the opening of the frame body 16 and the rear wall of the dust collection container storage portion 5 communicating with the electric blower chamber 7. When the seal packing 33 is provided and the dust collection container 4 is stored in the dust collection container storage part 5, the peripheral part on the rear side of the lid part 4b and the rear wall of the dust collection container storage part 5 are sealed. The seal packing 33 is formed integrally with the frame body 16. When the dust collection container 4 configured in this way is stored in the dust collection container storage section 5, the sealing section 4a, the storage section 4a and the lid section 4b are joined by the respective sealing means. The air inlet and the air inlet of the electric blower 6 communicate with each other in an airtight manner by sealing the joint between the air inlet and the opening peripheral portion of the rear part of the lid part 4b and the rear wall of the dust container storage part 5. Is done.

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

  When suction is started by driving the electric blower 6, dust on the surface to be cleaned is sucked from a floor suction tool (not shown). The dust contained in the sucked air passes through the communication port 12 of the dust collecting container 4 and strikes the net-shaped prefilter 32 in a straight line. At this time, coarse dust is filtered by the pre-filter 32, and fine dust passes through the pre-filter 32 together with air and hits the filter 17 which is the next main filter. The filter 17 has a large pressure loss and cannot easily pass through, and the fine dust and air that collide with the filter 17 travels in a straight and upward direction along the straight ridges and valleys of the pleated filter 17. To do. However, since the coupling portion between the accumulation portion 4a and the lid portion 4b is tightly sealed by the seal packing 18, fine dust is not discharged outside the dust collecting container 4, and the dust collecting container storage portion 5 is not soiled.

  As the suction continues, coarse dust accumulates in the accumulating portion 4a and fine dust that has passed through the prefilter 32 adheres to the peaks and valleys of the filter 17 of the lid portion 4b, and the filter 17 becomes clogged. The suction force will be reduced. In particular, when dust such as cement or powder is sucked, the filter 17 is clogged significantly.

  Thus, the dust stuck to the peak and valley of the filter 17 is slid along the protruding portion 23 so that the contact portion 29 of the dust remover 24 and the reinforcing portion 22 provided on the filter 17 are formed. It is possible to remove the entire fine dust adhering to the surface of the filter 17 by vibrating so that the peak portion of the filter 17 touches and shakes. Further, the fine dust adhering to the valley (deep part) is removed by bending the dust removing body 24 in a direction perpendicular to the surface of the filter 17 and applying vibration that strikes the reinforcing part 22 of the filter 17 with the contact part 29. be able to.

  Further, since the contact portion 29 of the dust removing body 24 is made of a material harder than the reinforcing portion 22 of the filter 17, dust is separated from the valley portion and the surface when the filter 17 is bent and struck in a direction perpendicular to the surface of the filter 17. The sex can be further improved.

  It should be noted that the sliding vibration and the rocking vibration may be either vibration depending on the type and amount of dust attached to the filter 17, and it goes without saying that the dust removal operation by vibrating both is more effective.

  As described above, in the present embodiment, the dust removing body 24 is slidable on the protrusion 23 and swingable in the direction perpendicular to the surface of the filter 17, so that On the other hand, the vibration that is slid in the orthogonal direction and fluctuates the peak portion and the vibration that is swung in the direction perpendicular to the surface of the filter 17 and strikes the valley portion (deep portion) are applied to the filter 17. In addition to removing dust attached to the surface, it is also possible to reliably remove dust attached to or adhered to the deep part of the valley.

  Further, by forming the contact portion 29 of the dust removing body 24 with a material harder than the reinforcing portion 22 of the peak portion of the filter 17, the vibration due to the sliding of the dust removing body 24 and the vibration of the tapping due to the swinging are stronger in the filter 17. As a result, the dust removal effect can be further improved.

  As described above, the vacuum cleaner according to the present invention can surely remove the dust adhered to or adhered to the surface and deep part of the filter, and thus is particularly useful for home and commercial vacuum cleaners. .
