The second charging unit starts charging the second power storage unit. At the same time, the first charging means also starts charging the electric energy of the second power storage means to the first power storage means.

  When the user finishes cleaning, removes the plug from the outlet, removes the dust collecting means from the main body of the vacuum cleaner, takes it over the trash box and discharges the dust in the dust collecting means, pressing the dust removal switch will The means and the driving means are electrically connected, and the driving means moves the dust removing means to vibrate the inner wall and components of the dust collecting means. Thereby, the dust adhering to the inner wall and bottom surface of the dust collecting means can be removed on the spot. Thereafter, the user clears the vacuum cleaner. Due to the vibration operation, the first power storage means is discharged and has no electrical energy. When the dust collecting means is returned to the main body of the vacuum cleaner, there is no power supply from the commercial power source because the plug is removed from the outlet. However, the first charging means operates with the electric energy stored in the second power storage means, and can charge the discharged first power storage means with the electric energy of the second power storage means.

  This way, the next time the user takes out the vacuum cleaner to clean, and before inserting the plug of the power cord into the outlet, he / she is worried about the state of the dust collecting means and removes the dust collecting means from the main body of the cleaner. Even when the dust removal switch is pressed in order to discharge the dust, the first power storage means is already charged, so that the dust collection means can perform the dust removal operation.

  Thus, while the user is cleaning, the first power storage means and the second power storage means are charged, and the electric energy of the second power storage means can be obtained even when no power is supplied from the commercial power source. By charging the first power storage means, the user can use the dust removal function of the dust collecting means at any time without being aware of the charging operation and the state of charge of the first power storage means.

Thereby, the dust adhering to the inner wall and bottom surface of the dust collecting means can be removed on the spot. Thereafter, the user clears the vacuum cleaner. Due to the vibration operation, the first power storage means is discharged and has no electrical energy. When the dust collecting means is returned to the main body of the vacuum cleaner, there is no power supply from the commercial power source because the plug is removed from the outlet. However, the first charging means operates with the electric energy stored in the second power storage means, and can charge the discharged first power storage means with the electric energy of the second power storage means.

  This way, the next time the user takes out the vacuum cleaner to clean, and before inserting the plug of the power cord into the outlet, he / she is worried about the state of the dust collecting means and removes the dust collecting means from the main body of the cleaner.

However, it plays the mountain fold 41a of the filter 41 and propagates the vibration to the entire dust collecting container 3 around the filter 41. Due to this vibration and impact, fine dust adhering to the back surface of the filter 41 (surface on the dust collection chamber 32 side) is screened out and collected in the dust collection chamber 32, and the filtration performance of the filter 41 is restored. .

  Next, the control method of the vacuum cleaner in this Embodiment is demonstrated using FIG. First, the inside of the dust container 3 surrounded by a dotted line will be described. In the present embodiment, the first power storage means 37 is composed of an electric double layer capacitor or the like, and this first power storage means 37 is connected to the power receiving terminal 38 and is a power supply terminal on the cleaner body 1 side. The electrical energy supplied from 17 is stored.

  The dust removal switch 34 is connected between the first power storage means 37 and the dust removal motor 46. When the dust removal switch 34 is turned on, the first power storage means 37 and the dust removal motor 46 are electrically connected to each other. The dust removal motor 46 is rotationally driven by the electrical energy of the power storage means 37.

The vacuum cleaner main body 1 surrounded by the dotted line is supplied with power from the commercial power source 50 by inserting the plug 11 (FIG. 1) of the power cord 10 into an outlet (not shown). The cleaner main body 1 has a control means 20 composed of a microprocessor, an IC memory, etc., and receives operation information from the hand operating section 5 by the user, and controls the operation of the cleaner main body 1 and the like.

  The control means 20 is connected to the second charging means 22 and performs control to turn on / off the second charging means 22. The second charging unit 22 is a DC power source obtained from the commercial power source 50 with a switching power source or the like, and is a power source for charging the second power storage unit 23.

  Here, the 2nd electrical storage means 23 is comprised with the electrical double layer capacitor. The second voltage detection means 25 monitors the voltage of the second power storage means 23 of the cleaner body 1 and is less than a preset threshold value (3.1 V in this embodiment). If it is, a signal is sent to the control means 20.

  The first charging unit 24 is a DC power source obtained from the second power storage unit 23 and charges the first power storage unit 37 of the dust collecting container 3 via the power feeding terminal 17 and the power receiving terminal 38. The first voltage detection means 27 monitors the voltage of the first power storage means 37 of the dust collecting container 3 through the power supply terminal 17 and the power reception terminal 38, and sets a preset threshold value (in this embodiment). Is less than 2.1V), an operation signal is sent to the first charging means 24 to control ON / OFF of the first charging means 24.

  Further, the first charging unit 24 uses a signal from the control unit 20 to supply electric energy serving as a supply source for charging the first power storage unit 37 of the dust collecting container 3 to a commercial power source or a second of the cleaner body 1. Is selected by the power supply selection means 26. The notifying means 28 is means for notifying information of the first voltage detecting means 27 for detecting the voltage of the first power storage means 37 of the dust collecting container 3 by a level meter display or the like constituted by LEDs. When the user operates the operation means 29 constituted by a push switch or the like, the user is notified of the state of charge of the first power storage means 37.

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

  First, in order to perform cleaning, the user pulls out the power cord 10 from the cleaner body 1 and connects the plug 11 attached to the tip of the power cord 10 to an outlet. When the hand operation unit 5 is operated and, for example, the operation mode “strong” is selected, the control unit 20 sends a predetermined signal to the drive unit 21 based on the information from the hand operation unit 5, and the electric blower 2 is driven.

  The electric blower 2 starts to rotate and generates a suction force, so that the user can start cleaning. The dust on the cleaning surface is sucked in by suction force from a horizontally long opening (not shown) provided on the lower surface of the suction tool 8, and is transferred to the dust collecting container 3 in the cleaner body 1 through the extension pipe 7 and the hose 6. And is collected there.

  The suction air that does not contain dust that has passed through the dust collecting container 3 passes through the electric blower 2 and is released into the atmosphere from the exhaust port 9. In this way, cleaning by the user is performed.

  First, when the plug 11 is connected to the outlet, the control means 20 confirms the storage voltage of the second power storage means 23 mounted on the cleaner body 1 with the information of the second voltage detection means 25, When the voltage is less than 3.1 V, the second charging unit 22 is turned on to charge the second power storage unit 23 until the stored voltage becomes 3.1 V or higher.

By this charging control, the second power storage means 23 can maintain a voltage of 3.1 V or higher when the commercial power supply is energized. The control means 20 sends a control signal to the first charging means 24 in parallel with the control. According to this control signal, the first charging unit 24 sets the commercial power supply as insufficiently charged if the second storage unit 23 detected by the second voltage detection unit 25 is less than 3.1 V if the stored voltage is less than 3.1V. If it is 1 V or more, the second power storage means 23 is selected by the power supply selection means 26 as the power supply.

  Then, the first charging unit 24 charges the first power storage unit 37 of the dust collecting container 3 with the electric energy obtained from the selected power source through the power feeding terminal 17 and the power receiving terminal 38.

  When cleaning is completed, the user operates a stop button (not shown) of the hand operation unit 5. In response to this, the control means 20 sends a stop signal to the drive means 21 to stop the driving of the electric blower 2. Then, in order to save energy consumed by the vacuum cleaner body 1 with standby power, the plug 11 is removed from the outlet, and the collected dust is discarded.

  The user removes the dust collecting container 3 from the vacuum cleaner body 1 and moves it onto a trash can or the like as shown in FIG. 5, opens the cover 36 of the dust collecting container 3, and accumulates in the dust collecting chamber 32. Dust is discharged into the trash can.

  At this time, the collected dust is discharged into the trash box to some extent, but part of the dust remains attached to the inner wall and bottom surface of the dust collection chamber 32 and the lid 36. At this time, when the user turns on the dust removal switch 34, the dust removal motor 46 is rotated by the electric energy stored in the first power storage means 37 built in the dust collecting container 3, and the operation of the flip body 42 The entire dust collecting container 3 vibrates around the filter 41, and the vibration propagates not only to the filter 41 but also to the inner wall of the dust collecting chamber 32 and the lid 36 as shown in FIG. can do.

  After the garbage is thrown away, the charging capacity of the first power storage means 37 in the dust collecting container 3 is almost completely returned to the vacuum cleaner main body 1 and accommodated by the vibration operation. At this time, since the power supply from the commercial power supply 50 is cut off for the purpose of saving energy before throwing away the trash, the first power storage means 37 cannot be charged from the commercial power supply 50.

  A control block diagram at this time is shown in FIG. The 2nd electrical storage means 23 of the vacuum cleaner main body 1 is fully charged by the cleaning of the user before throwing away trash. Using this electric energy, the first power storage means 37 of the empty dust collection container 3 is charged.

  Further, the electric energy of the second power storage means 23 of the cleaner body 1 is also supplied as electric energy for operating the first charging means 24, the first voltage detecting means 27, the notifying means 28, and the operating means 29. Yes.

  First, when the dust collection container 3 is stored in the cleaner body 1, the first voltage detection means 27 detects the voltage of the first power storage means 37 of the dust collection container 3. If it is detected that it is empty (less than 2.1 V), an operation signal is sent to the first charging means 24. At this time, since the first charging means 24 has no signal from the control means 20 (the supply of the commercial power supply 50 is cut off), the second power storage means of the cleaner body 1 using the supply power selection means 26 is used. 23 is selected as the power source.

  Thereby, the first charging means 24 can charge the electric energy of the second power storage means 23 to the first power storage means 37 of the dust collecting container 3. If charging proceeds and the first voltage detecting means 27 detects 2.1 V or more, it is determined that charging to the first power storage means 37 is completed, and a stop signal is sent to the first charging means 24, Stop charging.

Thus, even if the power supply from the commercial power supply is interrupted, the first energy collection container 3 that has been emptied by using the electric energy charged in the second power storage means 23 built in the cleaner body 1 is used. The power storage means 37 can be charged. This operation can be repeated any number of times until the second power storage means 23 of the cleaner body 1 is empty.

  As a result, the next time the user takes out the electric vacuum cleaner to be cleaned, and before the plug 11 is inserted into the outlet, the state in the dust collecting container 3 is anxious, and the dust collecting container 3 is vacuumed. Even when the dust removal switch 34 is pressed in order to remove dust from the main body 1, the first power storage means 37 is already charged, so that the dust removal operation in the dust collecting container 3 can be performed. Can be done.

  As described above, the vacuum cleaner body 1 is carried to the place where the commercial power source 50 is installed, or the plug 11 of the power cord 10 is connected to an outlet for charging the first power storage means 37 of the discharged dust collecting container 3. Even if the user wants to use the first power storage means 37, the user is not conscious of the charging operation and the state of charge of the first power storage means 37. The dust removal function of the dust container 3 can be used at any time.

  Further, since the first voltage detection means 27 monitors the voltage of the first power storage means 37 of the dust collecting container 3, when the user presses the operation means 29 provided in the cleaner body 1, The information can be notified to the user by a level meter display (notification means 28) constituted by LEDs. In this operation, as described above, the electric energy of the second power storage means 23 of the cleaner body 1 is also supplied as the electric energy that the first voltage detection means 27, the notification means 28, and the operation means 29 operate. Therefore, notification can be made without using the electric energy of the first power storage means 37 of the dust collecting container 3, that is, without shortening the time of the dust removal operation performed by the user.

  As described above, when the user is wondering whether the dust removal operation is possible even if the plug is not inserted into the outlet and the commercial power supply 50 is not supplied to the electric vacuum cleaner, the first power storage means is provided. Since the amount of electrical energy stored in 37 can be confirmed by the notification means 28, the dust removal function of the vacuum cleaner can be used with peace of mind. It is possible to provide a vacuum cleaner that has good usability and high satisfaction for the user.

  In the above-described embodiment, each of the first power storage unit 37 and the second power storage unit 23 is described as being configured with an electric double layer capacitor, but may be implemented with a secondary battery.

  As described above, the vacuum cleaner according to the present invention can efficiently remove dust adhering to the inner wall and the bottom of the dust collecting means when throwing away garbage, and can be used for various households having a dust removing function using the power storage means. Widely applicable to commercial vacuum cleaners.
