Description

  The present invention relates to a vacuum cleaner that opens a dust collection cover that covers a dust collection chamber opening by an urging force.

As a conventional electric vacuum cleaner of this type, there is one provided with a biasing means that always biases in the opening direction (see, for example, Patent Document 1).
Japanese Utility Model Laid-Open No. 5-25562

  However, in the above-described conventional configuration, in order to cover the dust collection chamber opening with the dust collection cover and maintain confidentiality, a locking means is required to keep the closed state, and extra operation occurs when opening. In addition, there were many parts.

  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described conventional problems, and to provide an easy-to-use vacuum cleaner that maintains an airtight state regardless of the locking means and does not need to open the locking means each time it is opened. And

  In order to solve the above-described conventional problems, an electric vacuum cleaner according to the present invention includes an electric blower that emits suction air, a main body that includes the electric blower, a dust collection chamber that has an opening, and a rotatable main body. And a biasing means for biasing the dust collecting part lid, the biasing means being arranged in the vicinity of the closed state of the dust collecting part lid. By energizing the dust collecting portion cover in the closing direction and energizing the dust collecting portion cover in the opening direction except in the vicinity of the closed state, the air collecting state is maintained and opened without providing a locking portion. Even in this case, it can be opened by slightly lifting the lid.

  The vacuum cleaner of the present invention can provide an easy-to-use vacuum cleaner that can easily open and close the dust collector lid.

  A first aspect of the present invention is an electric blower that emits suction air, a main body incorporating the electric blower, a dust collection chamber having an opening, and is rotatably attached to the main body, and covers the opening in an openable and closable manner. And a biasing means for biasing the dust collector lid, and the biasing means biases the dust collector lid in the closing direction when the dust collector lid is in the closed state. The dust collecting unit cover is urged in the opening direction except in the vicinity of the closed state, and the urging means urges the dust collecting unit cover in the closing direction in the vicinity of the closed state, so that the locking part is not provided. However, even when the airtight state is maintained and the cover is opened, it can be opened only by slightly lifting the lid, and a highly usable vacuum cleaner can be provided.

  In the second invention, the urging means of the first invention is positioned in the direction of closing the opening in the vicinity of the dust collection cover closed state, and moves beyond the rotating shaft when the dust collection cover is opened. By arranging at the position where the biasing force that opens the dust collecting lid acts, the biasing force in the reverse direction can be realized by one biasing means.

  According to a third aspect of the present invention, the biasing means of the first or second aspect of the present invention is a torsion coil spring, and is arranged on the substantially center line of the dust collecting portion lid, so that the lid can be reliably prevented from being twisted during rotation. By using a torsion coil spring, it is possible to obtain an opposition force that counteracts in a small space.

  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)
The vacuum cleaner in the 1st Embodiment of this invention is demonstrated using FIGS. FIG. 1 is an overall perspective view of the vacuum cleaner according to the present embodiment, FIG. 2 is a perspective view of the main body of the vacuum cleaner, and FIG. 3 is a perspective view of the main body when the dust collector lid of the vacuum cleaner is opened.

  1 and 2, reference numeral 1 denotes a main body of the vacuum cleaner, which includes an electric blower (not shown) and a dust collecting means (not shown). A suction port 4 to which the pipe 3 is detachably connected is provided. The other end of the hose 2 is provided with a hand grip pipe 6 having a grip portion 5 that is gripped during cleaning. Reference numeral 7 denotes a telescopic or jointable suction pipe, whose downstream end is detachably connected to the hand grip pipe, and the other end is detachably connected to the floor suction tool 8.

  In FIG. 3, the cleaner body 1 includes a dust collection chamber 9, and a dust collection lid 10 that covers the dust collection chamber 9 so as to be freely opened and closed is provided. A dust collection bag (not shown) for collecting dust is detachably provided in the dust collection chamber 9, and the dust collection lid 10 is rotatably attached to the main body 1 by a rotation shaft 11. A torsion coil spring 12 is provided in the vicinity of the rotating shaft 11 as an urging means.

  4, 5 and 6 are schematic views showing the relationship between the dust collection lid 10 and the torsion coil spring 12 from the closed state to the open state.

  FIG. 7 shows a side view of the main body in the opened state.

  The operation of the above configuration is as follows.

  In the use state or the storage state, the urging force action point 13 of the torsion coil spring 12 is located behind the rotating shaft 11 of the dust collecting lid 10. Power is acting. Due to this inability, the opening of the dust collection chamber 9 is kept airtight by the dust collection lid 10. Since the locked state can be maintained by the urging force of the spring, a system support for locking the dust collecting lid 10 is not necessary.

  When the dust collection lid 10 is opened, by pulling up the dust collection lid 10, a force that moves forward acts on the torsion coil spring 12, and the biasing force action point 13 of the torsion coil spring 12 rotates as the spring moves. By moving forward from the moving shaft 11 and an urging force in the opening direction acts on the dust collecting lid 10, the dust collecting lid 10 is opened and the dust collecting bag can be easily taken out. The relationship between the dust collection lid 10 and the torsion coil spring 12 when the dust collection lid 10 is closed is the reverse of that when the dust collection lid 10 is opened.

  By taking the state opened 90 degrees or more from the closed state as the open state, the dust bag can be easily taken out.
