(Embodiment 1)
FIG. 1 shows a configuration diagram of a vacuum cleaner according to Embodiment 1 of the present invention. In FIG. 1, an extension tube 2 having a suction tool 3 detachably attached to the tip is connected to a hand handle 4, a hose 5 extending from the hand handle 4 is detachably connected to the main body 1, and the main body 1 is free from dust. It has a dust collection chamber body 11 that accumulates and can be detached from the main body 1.

  FIG. 2 shows a cross-sectional view of the main body 1. The main body 1 has a built-in electric blower 12 that generates suction air for sucking dust, and suction air flows into the intake port of the electric blower 12 through the filter 18 and the communication port 19 of the dust collecting chamber body 11. To do.

  In order to prevent the dust collection chamber body 11 from coming off without permission, the main body 1 is provided with a removal prevention means 34 comprising a slide-type lock, and the removal prevention means 34 is moved forward of the main body (on the dust collection chamber body 11 side). (Hereinafter, this operation is referred to as “setting”) prevents the dust collection chamber body 11 from being detached from the main body 1, and is moved to the rear of the main body (hereinafter, this operation is referred to as “release”). 11 can be removed from or attached to the main body 1. Further, the removal preventing means 34 has a structure that cannot be set when the dust collection chamber body 11 is not correctly mounted. At the same time as setting, the user also checks whether the dust collection chamber body 11 is correctly mounted. Can do.

  In addition, the main body 1 includes attachment / detachment detection means 35 including a switch for detecting whether or not the dust collection chamber body 11 is mounted. When the dust collection chamber body 11 is mounted on the main body 1, the switch is pushed, It is detected that the dust collection chamber body 11 is attached to the main body 1.

  In the vicinity of the filter 18, a vibration device that is a dust removing means 31 is provided, and the dust removing means 31 includes a vibrator 13 that vibrates the dust collection chamber body 11 and an electromagnet 17 that operates the vibrator 13. The electromagnet 17 is formed of a coil 15 and a core 16 and is disposed in the vicinity of the vibrator 13 so as to vibrate the vibrator 13 by a magnetic field. The dust removal control means 32 includes a control circuit (not shown) for controlling the current flowing through the electromagnet 17 and a dust removal switch 21 (see FIG. 4) installed on the display panel 20. When the dust removal switch 21 is operated while the dust removal means 31 is stopped, the control circuit of the dust removal control means 32 rectifies the AC voltage of the power source to the coil 15 by half-wave rectification by a rectification means (not shown) such as a diode. Applied voltage. Since the applied voltage is a half-wave rectified voltage, the current flowing through the coil 15 is intermittent, and the magnetic field generated from the electromagnet 17 is also intermittent. As a result, the electromagnet 17 repeatedly attracts and separates the vibrator 13 and gives vibration to the vibrator 13, and the vibrator 13 strikes the filter 18 of the dust collection chamber body 11 to vibrate the dust collection chamber body 11 and the filter 18. And remove dust adhering to them. When the dust removal switch 21 is operated during the dust removal operation, the control circuit stops supplying power to the coil 15 and the vibration of the vibrator 13 stops. In the present embodiment, by directly hitting the filter 18 in the middle of the intake path, dust attached to the filter 18 that causes a reduction in the air volume can be removed intensively.

  FIG. 4 is a front view of the display panel 20 of FIG. 2, in which a dust removal operation notification means 33 and a dust removal permission notification means 36 comprising a dust removal switch 21 and LEDs are installed.

  FIG. 5 shows a control block diagram of the vacuum cleaner. In FIG. 5, 31 is a dust removal means for performing dust removal operation, 32 is a dust removal control means for controlling the dust removal means 31, 33 is a dust removal operation notification means for notifying the stop of dust removal, and 34 is for removing the dust collecting chamber body 11. Detachment preventing means 35 for preventing and removing, 35 is an attachment / detachment detecting means for detecting attachment / detachment of the dust collecting chamber body 11, and 36 is a dust removal permission notifying means for notifying that the dust removal control means does not prohibit the operation of the dust removing means 31. .

  The operation of the vacuum cleaner configured as described above will be described.

When the electric blower 12 operates to generate a suction force, dust is sucked into the dust collection chamber body 11 from the suction tool 3 together with the suction air. The dust collection chamber body 11 has a filter 18. The dust is filtered by the filter 18, and only the suction air from which the dust has been removed is sucked into the electric blower 12 through the communication port 19, and the dust collection chamber body 11. Dust accumulates on the surface. At this time, since the suction air always passes through the vicinity of the communication port 19 of the filter 18, dust is most likely to adhere to this vicinity. As shown in FIG. 3A, when dust adheres to this area, the dust attached to the filter 18 prevents the suction air from passing even if the dust collecting body 11 does not accumulate much dust. As a result, the suction force decreases and the cleaning efficiency deteriorates.

  Therefore, the user operates the dust removal switch 21 to vibrate the filter 18 of the dust collecting chamber body 11 with the vibrator 13 and to blow off the dust adhering to the vicinity of the communication port 19 of the filter 18 to restore the suction air volume. Cleaning efficiency can be maintained (see FIG. 3B). Further, when the user operates the dust removal switch 21 again during the dust removal operation, the dust removal means 31 can be stopped at an arbitrary timing.

  As shown in the following example, the dust removal control means 32 may operate and stop the dust removal means 31 without the user operating the dust removal switch 21, and in this case, the user does not notice the dust removal operation. There is. Therefore, by turning on and off the LED of the dust removal operation notification means 33, the user can know whether or not the dust removal operation is being performed, and usability can be improved. Further, when the dust removal operation is prohibited, the dust removal means 31 does not operate even if the dust removal switch 21 is operated. Therefore, when the operation of the dust removal means 31 is not prohibited, the LED of the dust removal permission notification means 36 is turned on, so that the user can be notified of the timing at which dust removal is possible and the usability can be improved.

  When dust is removed by vibration of the dust removing means 31 or when the dust collecting chamber body 11 is not attached to the main body 1, dust removal may not be effective even when the user performs dust removal by operating the dust removal switch 21. Therefore, when the attachment / detachment detection means 35 detects the detachment of the dust collecting chamber body 11, by prohibiting the operation of the dust removal means 31, useless dust removal operation can be prevented and dust removal can be performed efficiently.

  The above example will be described using the time table of FIG. When the dust removal switch 21 is operated while the dust collection chamber body 11 is mounted on the main body 1, (a) the dust removal control means 32 operates the dust removal means 31 and turns on the LED of the dust removal operation notification means 33. When the dust removal switch 21 is operated again during the operation of the dust removal means 31, (b) the dust removal control means 32 stops the dust removal means 31 and turns off the LED of the dust removal operation notification means 33. When the dust removal switch 21 is operated again here, (c) the dust removal control means 32 operates the dust removal means 31 again and turns on the LED of the dust removal operation notification means 33. Here, when the dust collection chamber body 11 is removed from the main body 1, (d) the dust removal control means 32 prohibits the operation of the dust removal means 31 and turns off the LED of the dust removal permission notification means 36. At this time, when the dust removing means 31 is operating, the operation is stopped. While the dust collection chamber body 11 is not attached to the main body 1, even if the dust removal switch 21 is operated, the (e) dust removal control means 32 does not operate the dust removal means 31. When the dust collection chamber body 11 is attached to the main body 1, (f) the dust removal control means 32 releases the operation prohibition of the dust removal means 31 and turns on the LED of the dust removal permission notification means 36. At this time, since the dust removing means 31 is stopped, by operating the dust removing switch 21 again, (g) the dust removing control means 32 operates the dust removing means 31 again. By performing the above operation, useless dust removal operation can be prevented and dust removal can be performed efficiently.

Also, immediately after the dust collection chamber body 11 is filled with dust due to cleaning, the user removes the dust collection chamber body 11 from the main body 1 to discard the dust, and cleans the dust collection chamber body 11 and the filter 18. In addition, not much dust is attached to the filter 18, and even if dust removal is performed immediately after the dust collection chamber body 11 is mounted on the main body 1 in this state, the dust removal effect cannot be obtained. Therefore, the dust removal control means 32 has a first predetermined time (after the attachment / detachment detection means 35 detects the attachment of the dust collecting chamber body 11 to the main body 1 (
For example, for 10 minutes, the operation of the dust removing means 31 is prohibited, and the dust removing operation in a state where the dust collecting chamber body 11 and the filter 18 are not sucking up dust immediately after cleaning is prohibited, and the dust is efficiently removed. be able to.

  The above example will be described with reference to the time table of FIG. The dust removal control means 32 includes a timer therein and measures the time since the dust collection chamber body 11 is mounted on the main body 1. When the dust collection chamber body 11 is attached to the main body 1, (a) the dust removal control means 32 detects a signal from the attachment / detachment detection means 35 and starts measuring the time of the timer. The dust removal control means 32 prohibits the operation of the dust removal means 31 until the time measured by the timer reaches 10 minutes, and turns off the LED of the dust removal permission notification means 36. Even if the dust removal switch 21 is operated at this time, the dust removal control means 32 does not operate the dust removal means 31. When the measurement time of the timer reaches 10 minutes, (c) the dust removal control means 32 releases the prohibition of the operation of the dust removal means 31 and turns on the LED of the dust removal permission notification means 36. At this time, since the dust removing means 31 is stopped, by operating the dust removing switch 21 again, (g) the dust removing control means 32 operates the dust removing means 31 again. By performing the above operation, it is possible to prohibit the dust removal operation in a state where the dust is not sucked in immediately after cleaning the filter 18 and the dust removal efficiency is not good, and the dust can be efficiently removed. Moreover, about the time which prohibits operation | movement of the dust removal means 31, time measurement according to the actual use time of a vacuum cleaner is performed by performing time measurement of a timer only during operation, or not only time measurement using a timer, It is possible to change the period of stopping the dust removing means 31 according to the usage status of the cleaner, such as stopping until the electric blower 12 is operated, and to perform more efficient dust removal according to the actual usage status. it can.

  Conversely, by operating the dust removing means 31 for a second predetermined time (for example, 5 seconds) when the dust collecting chamber 11 is mounted on the main body 1, the user is informed that dust removal is effective and used. Can be improved. In this case, since the purpose of operating the dust removing means 31 is different, an operation different from the normal dust removing operation, for example, by increasing the power supplied to the dust removing means 31 to increase the vibration of the dust removing means 31 than usual, By periodically turning the means 31 on and off (for example, every 0.5 seconds), the vibration sound of the dust removing means 31 is made different from the normal sound, and the user is clearly informed that dust removal is effective. Can do.

  The above example will be described with reference to the time table of FIG. The dust removal control means 32 includes a timer as in the above example, and measures the time from when the dust collection chamber body 11 is mounted on the main body 1. When the dust collection chamber 11 is mounted on the main body 1, (a) the timer starts measuring time, the dust removal control means 32 increases the power supplied to the dust removal means 31 more than usual, and the vibration of the dust removal means 31 is reduced. Make it stronger than usual. When the measurement time of the timer reaches 5 seconds, (b) the dust removal control means 32 stops the operation of the dust removal means 31. By performing the above operation, it is possible to clearly notify the user that dust removal is effective.

  In the above description, an example in which the attachment / detachment detection unit 35 is used to detect attachment / detachment of the dust collection chamber body has been described. In this case, a switch or the like for newly detecting the attachment / detachment of the dust collection chamber body 11 is described. It is necessary to provide a device. Therefore, in general, a vacuum cleaner in which the dust collection chamber body 11 is detachable has the removal prevention means 34. When removing the dust collection chamber body 11 from the main body 1, it is necessary to release the removal prevention means 34. Taking advantage of this, the removal prevention means 34 can be used in place of the attachment / detachment detection means 35. In this case, although the moment of attachment / detachment of the dust chamber 11 cannot be accurately detected, the attachment / detachment of the dust chamber can be detected without providing a new device for detecting the attachment / detachment of the dust chamber. it can. In this case, detection can be performed by setting and releasing the removal preventing means 34 instead of detection of mounting of the dust collecting chamber body 11, and the same effect can be obtained by performing the dust removal operation described above. .

Further, in this case, there is still a time during which the dust collecting chamber body 11 is still attached to the main body 1 even when the removal preventing means 34 is released. In this case, when dust removal is necessary, such as when the removal prevention means 34 is released during the dust removal operation, the vibration of the dust removal means 31 is made stronger than usual for 5 seconds, or the dust removal means 31 is turned on every 0.5 seconds. By turning it off, the user can be informed that dust removal is still necessary, and usability can be improved.

  The above example will be described using the time table of FIG. The dust removal control means 32 includes a timer as in the above example, and measures the time after the removal prevention means 34 is released. When the removal prevention means 34 is released when the dust removal switch 21 is operated by operating the dust removal switch 21, (b) the timer starts measuring time, and the dust removal control means 32 is removed from the dust removal means 31. The electric power supplied to is increased more than usual, and the vibration of the dust removing means 31 is made stronger than usual. When the measurement time of the timer reaches 5 seconds, (c) the dust removal control means 32 stops the operation of the dust removal means 31. By performing the above operation, the user can be notified that dust removal is still necessary, and usability can be improved.

  As described above, the electric vacuum cleaner according to the present invention can efficiently remove dust in the dust collecting chamber, and can provide an electric vacuum cleaner capable of sucking more dust.
