Description

  The present invention relates to a vacuum cleaner used in general households.

  A conventional vacuum cleaner will be described with reference to FIGS.

The vacuum cleaner main body 1 includes an electric blower 2 and is configured by a dust collection chamber 3 disposed in front of the electric blower 2. The upper portion of the vacuum cleaner main body 1 covers the dust collection chamber 3 and is rotatably supported by a dust collection chamber. A chamber lid 4 is provided. A dust collection bag 5 for collecting dust is provided in the dust collection chamber 3, and a mouth plate 6 provided on the dust collection bag 5 is provided on the front side of the main body 1 by guides 7 provided on both sides of the dust collection chamber 3. The mouth plate 6 is detachably held by a holder 10 provided on the main body front side partition wall 9. Extruding means 18 for pushing the mouth plate 6 to the rear of the dust collecting chamber 3 is provided on the front partition wall 9, and moving means 19 for moving the mouth plate 6 upward is provided at the bottom of the dust collecting chamber 3 corresponding to the guide 7. Then, the dust collection chamber lid 4 is opened and the mouth plate 6 held by the holder 17 is opened, and the mouth plate 6 is projected upwardly from the dust collection chamber 3 by the pushing means 18 and the moving means 19 ( For example, see Patent Document 1).
Japanese Patent No. 3154316

  In the conventional configuration, the dust bag is projected upward by the moving means that moves the mouth plate portion upward. However, when dust accumulates in the dust bag, the dust bag is closer to the dust bag side than the mouth plate portion. However, since the weight increases, there is a problem that it is difficult to protrude the dust bag side upward even if only the mouth plate portion is moved by the moving means.

  This invention solves the said subject, and it aims at providing the vacuum cleaner which can take out a dust bag easily.

  In order to solve the above-described conventional problems, the electric vacuum cleaner of the present invention includes an electric blower that emits suction air, a dust collection bag that collects dust sucked by the electric blower, and an opening. A dust collection chamber for storing the bag; an openable / closable dust collection chamber cover for covering the opening of the dust collection chamber; and the dust collection bag provided inside the dust collection chamber so as to face the lower surface of the dust collection bag. And the pushing means for urging the dust bag toward the opening, so that the dust bag is easily protruded upward by pushing and pushing the dust bag portion that accumulates and accumulates dust. Easy to do.

  The vacuum cleaner of this invention can provide the vacuum cleaner which can take out a dust bag easily.

  According to a first aspect of the present invention, there is provided an electric blower that generates suction air, a dust collection bag that collects dust sucked by the electric blower, a dust collection chamber that has an opening and stores the dust collection bag, and the dust collection An openable and closable dust collecting chamber cover for covering the opening of the chamber, and an extrusion means provided inside the dust collecting chamber so as to face the lower surface of the dust collecting bag and biasing the dust collecting bag toward the opening. Since the dust collecting bag portion where dust is accumulated and the largest weight is urged, it is easy to push out, and the dust collecting bag easily protrudes upward and can be easily taken out.

  According to a second aspect of the present invention, there is provided an extruding spring as an extruding means, a holding portion for holding one end of the extruding spring facing the opening of the dust collecting chamber inside the dust collecting chamber, Since the other end is brought into contact with the lower surface of the dust bag, the dust bag easily protrudes upward at the same time as the dust chamber cover is opened, and can be easily taken out.

  In the third aspect of the invention, since the push plate is provided at one end of the push spring and the push plate is brought into contact with the lower surface of the dust bag, the dust bag can be pushed upward in a more stable state.

  In the fourth invention, since the extruded plate is formed of a breathable material, even if the dust collection bag is inflated, it is not in close contact with the dust collection chamber wall, and the intake passage is secured, so that the air flow reduction is reduced. The effect is also obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
A first embodiment of the present invention will be described with reference to FIG.

  The vacuum cleaner main body 1 includes an electric blower 2 and is configured by a dust collection chamber 3 disposed in front of the electric blower 2. The upper portion of the vacuum cleaner main body 1 covers the dust collection chamber 3 and is rotatably supported by a dust collection chamber. A chamber lid 4 is provided. A dust collection bag 5 for collecting dust is provided in the dust collection chamber 3, and a mouth plate 6 provided in the dust collection bag 5 is accommodated facing the suction port 8 provided on the front side of the main body. Is detachably held by a holder 10 provided on the front partition wall 9 of the main body. At least one or more pushing springs 11 are provided on the lower surface side of the dust collecting bag 5, and a holding portion 13 that holds the pushing spring 11 is provided integrally with the dust collecting chamber 3 at a position facing the opening 12 of the dust collecting chamber 3. One end 14 of the pushing spring 11 is held, and the other end 15 is provided with an pushing plate 16 so as to be in contact with the lower surface and the side surface of the dust bag 3. The pushing spring 11 has the other end 15 larger than the winding diameter of the one end 14. When the dust bag 5 is not attached to the dust collection chamber 3, the holder 10 rotates in a direction in which the dust collection chamber lid 4 does not close because the holder 10 interferes with a part of the dust collection chamber lid 4. The dust collection chamber cover 4 is provided so as to rotate in a closing direction without interference when mounted. The extruded plate 16 is formed in a lattice shape.

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

  Since the pushing spring 11 for pushing the dust collecting bag 5 toward the opening 12 of the dust collecting chamber 3 is provided on the lower surface of the dust collecting bag 5, the dust collecting bag portion where dust is accumulated and the largest weight is pushed out. When the dust collection chamber lid 4 is opened, the dust collection bag 5 easily protrudes upward and can be easily taken out. Further, since the pushing spring 11 has a larger other end 15 than the winding diameter of the one end 14, and the other end 15 is provided with the pushing plate 16, the contact area with the lower surface of the dust bag 5 is large and stable. Thus, the dust bag 5 can be pushed upward. The extrusion plate 16 is in contact with the outer peripheral side surface and the lower surface of the dust collection bag 5 and is formed in a lattice shape so that it adheres closely to the inner wall of the dust collection chamber 3 even if dust collects and spreads in the dust collection bag 5. And is easily pushed upward because of low frictional resistance. Furthermore, since the extrusion plate 16 is formed in a lattice shape, an intake passage is secured in the lattice portion, and a reduction in air volume can be reduced. Further, since the holder 10 that holds the mouth plate 6 in a detachable manner is provided, the dust collection bag 5 is prevented from unexpectedly protruding upward when the dust collection chamber cover 4 is opened and held. When the user releases the tool 10, the dust bag 5 can be protruded upward and easily taken out. Furthermore, the holder 10 can also prevent erroneous attachment of the dust bag 5.

  As described above, the vacuum cleaner according to the present invention is extremely useful for a vacuum cleaner equipped with a dust collection bag and the like because it is very easy to take out the dust collection bag.
