However, the mountain fold of the filter 9 is flipped, and the vibration propagates to the entire dust collecting container 3 around the filter 9. Due to this vibration and impact, fine dust adhering to the back surface of the filter 9 (the surface on the dust collection chamber 4 side) is screened out and collected in the dust collection chamber 4, and the filtration performance of the filter 9 is restored. .

  Next, the control method of the vacuum cleaner in this Embodiment is demonstrated using FIG. FIG. 3 is a control block diagram of the electric vacuum cleaner. First, the inside of the dust collecting container 3 will be described. The electric double layer capacitor 21 that is the power storage means 28 is connected to the power receiving terminal 20 and stores electric energy from the power receiving terminal 20. The dust removal switch 18 is connected between the electric double layer capacitor 21 and the dust removal motor 14. When the dust removal switch 18 is turned on, the electric double layer capacitor 21 and the dust removal motor 14 are electrically connected, and the electric double layer capacitor 21 The dust removal motor 14 rotates with energy.

  The voltage detection means 22 in the vacuum cleaner main body 1 monitors the voltage of the electric double layer capacitor 21 via the power supply terminal 19 and the power reception terminal 20, and is set to a preset threshold value (2. If it is less than 1V), an operation signal is sent to the charging control means 23. The charging control means 23 is composed of a semiconductor switch such as a transistor, and turns on / off the charging means 24 in response to an operation signal from the voltage detection means 22.

  The charging means 24 is a DC power source obtained by commercial power source switching or the like, and is a power source for charging the electric double layer capacitor 21 via the power feeding terminal 19 and the power receiving terminal 20 (in this embodiment, output 2. 1V).

  About the vacuum cleaner comprised as mentioned above, the operation | movement is demonstrated using FIG. When the electric vacuum cleaner is energized with the commercial power supply, the voltage detection means 22 first checks the storage voltage of the electric double layer capacitor 21, and if it is less than 2.1V, charge control is performed until the storage voltage becomes 2.1V or higher. The means 23 is operated to charge the electric double layer capacitor 21. By this charging control, the electric double layer capacitor 21 maintains a voltage of 2.1 V or more when the commercial power is turned on, and the voltage gradually decreases due to natural discharge even when disconnected from the commercial power, but about 2 V for a while. Will be maintained.

  Subsequently, when the user starts the operation of the vacuum cleaner, the sucked dust is accumulated in the dust collection chamber 4. Consider a case where dust accumulated in the dust collection chamber 4 is discarded. The user first removes the dust collection container 3 from the electric vacuum cleaner main body 1 and moves the dust collection container 3 onto a trash box or the like. Next, when the lid 7 is opened, the dust accumulated in the dust collection chamber 4 is discharged to some extent in the trash can, but the dust remains partially attached to the inner wall of the dust collection chamber 4 and the lid 7. .

  At this time, when the user turns on the dust removal switch 18, the dust removal motor 14 is rotated by the electric energy stored in the electric double layer capacitor 21, and the dust collecting container 3 as a whole vibrates around the filter 9 by the operation of the flip body 10. However, as shown in FIG. 4, the vibration propagates not only to the filter 9 but also to the inner wall of the dust collecting chamber 4 and the lid body 7, and the attached dust is removed.

  As described above, in the present embodiment, dust removal operation can be performed on the trash box when the trash is thrown away, so that not only the filter 9 but also dust attached to the inner wall of the dust collection chamber 4 and the lid 7 can be removed. . In addition, when the storage voltage of the electric double layer capacitor 21 is monitored and a storage voltage sufficient to carry out the dust removal operation is stored, the charging means 24 is stopped to save energy that does not consume unnecessary power. An excellent vacuum cleaner can be provided.

(Embodiment 2)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. Note that parts having the same configurations as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. An attachment / detachment switch 26 is attached to the partition wall 15 of the electric vacuum cleaner main body 1, and is configured to be turned on when the dust collecting container 3 is attached to the electric vacuum cleaner main body 1.

  When the electric vacuum cleaner is energized with the commercial power supply, the attachment / detachment detection means 25 sends an operation signal to the timer 27 to start counting for a predetermined time (30 seconds in the present embodiment) and to operate the charge control means 23. Charging of the electric double layer capacitor 21 is started. After 30 seconds, the timer 27 sends a signal to the attachment / detachment detection means 25, and the attachment / detachment detection means 25 stops the operation signal to the timer 27 and stops the charge control means 23 to charge the electric double layer capacitor 21. stop. In the present embodiment, since charging of the electric double layer capacitor 21 is completed in about 25 seconds, the electric double layer capacitor 21 becomes 2.1 V that is the output voltage of the charging means 24 after charging for 30 seconds. Here, if the attachment / detachment switch 26 detects the removal and remounting of the dust collecting container 3, it is assumed that the user has removed the dust using the energy of the electric double layer capacitor 21, so the attachment / detachment detection is performed. The means 25 again performs the charging operation for 30 seconds.

  As described above, in the present embodiment, by using the attachment / detachment detection means 25, there is no need to always operate the charging means 24, and when the charging is unnecessary, the charging means 24 can be stopped. A vacuum cleaner with excellent energy savings can be provided.

  In addition, if a low-voltage, low-current signal line via a contact is used to monitor the storage voltage of the electric double layer capacitor 21 as in the first embodiment, it is easily affected by the contact resistance of the contact portion. In order to detect the voltage with high accuracy, there is a problem that the circuit becomes complicated. However, according to this embodiment, the circuit can be simplified and the cost of the circuit can be reduced. It is also possible to combine Embodiments 1 and 2.

  In the first and second embodiments, the description has been made on the specification that the dust collecting container 3 alone performs the dust removing operation when the user operates the dust removing switch 18. However, the greatest effect of the present invention is the top of the trash can. In order to remove dust adhering to the inner wall of the dust collection chamber 4 and the lid body 7 that could not be removed in the past by performing the dust removal operation in the above-described manner, it is possible to remove dust adhering to the current mainstream or vacuum cleaner. Needless to say, the same effect can be obtained even if the dust collecting container 3 according to the present invention is added to a vacuum cleaner that performs a dust removing operation on the filter when the operation is stopped.

  As described above, the vacuum cleaner according to the present invention can remove not only the filter surface of the dust collecting means but also the dust attached to the inner wall and bottom face of the dust collecting means, and is easy to use. It can be applied to various vacuum cleaners for shops and stores.
