Description

Electric vacuum cleaner

The present invention relates to a vacuum cleaner that removes dust adhering to the inner surface of a dust collection chamber by vibrating the dust collection chamber.

For example, Patent Document 1 proposes an example in which a conventional vacuum cleaner removes fine dust adhering to a dust collection filter surface with an arm (dust removal unit) driven by a motor having a speed reduction mechanism. According to Patent Document 1, an arm is moved by a motor and, for example, a pleated portion of a substantially planar dust collecting portion composed of a pleated dust collecting filter is sequentially beaten to give vibrations to the surface of the dust collecting filter. The adhering fine dust was shaken off and removed. Thereby, the fall of the suction performance of the vacuum cleaner was suppressed. In other words, the conventional configuration exhibits a great effect for dust removal on the dust collection filter surface.

However, most of the dust removed from the dust collection filter surface can be discarded, but part of the dust adheres to the inner wall and bottom surface of the dust collection chamber. However, in the conventional vacuum cleaner, the dust separation property at the time of throwing away the dust attached to the dust collecting chamber has not been considered.

Moreover, the partition 15 of the vacuum cleaner main body 1 shown in FIG. 1B is provided with a power supply terminal 19 for energizing the power storage unit 28 provided in the dust collecting container 3 shown in FIG. 1C. A dust receiving container 3 is provided with a power receiving terminal 20 that is paired with the power feeding terminal 19 of the dust collecting container 3. Thereby, when the dust collecting container 3 is attached to the main body 1 of the vacuum cleaner, the power feeding terminal 19 and the power receiving terminal 20 are connected.

Hereinafter, the internal configuration of the dust collecting container 3 of the present embodiment will be described with reference to FIG. FIG. 2 is a cutaway perspective view of the dust collecting container in the same embodiment.

As shown in FIG. 2, the filter unit 5 constituting the dust removing unit 5 includes a frame 8, a pleat-folded filter 9 provided in the frame 8 with the pleats in the vertical direction, and a dust removing operation unit 29. It consists of and.

And the dust removal operation | movement part 29 is comprised from the flip body 10, the dust removal gear 11, the dust removal connection rod 12, the fixed rod 13, and the dust removal motor 14. Here, the flip body 10 is slidable in the lateral direction along the fixed rod 13. The dust removal gear 11 is provided to be rotatable with respect to the filter unit 5. The dust removal connecting rod 12 connects the outer periphery of the dust removal gear 11 and a part of the flip body 10.

Further, on the surface of the flip body 10 facing the filter 9, there are provided protrusions (not shown) that come into contact with each fold portion of the pleated filter 9.

The fixing rod 13 is fixed to the frame 8, and the rotating shaft of the dust removing gear 11 is fixed to the fixing rod 13. Thereby, the operation | movement (movement) direction of the flip body 10 is controlled by the horizontal direction (arrow in FIG. 2) on either side.

Also, a tooth profile that meshes with the dust removal gear 11 is formed on the side of the dust removal connecting rod 12 facing the dust removal gear 11. Then, when the dust removal gear 11 rotates forward or reversely, the dust removal connecting rod 12 slides, and the flip body 10 connected to the dust removing connecting rod 12 moves in the left-right direction.

The dust removal motor 14 includes a gear that meshes with the dust removal gear 11, and is connected to the dust removal gear 11 through the gear of the dust removal motor 14. The dust removal motor 14 rotates to transmit power to the dust removal gear 11.

The operation of the filter unit 5 which is a dust removing unit having the above configuration will be described below.

First, when the dust removal motor 14 is rotated, the dust removal gear 11 is rotated, and the flip body 10 connected via the dust removal connecting rod 12 reciprocates left and right. At this time, the projection provided on the repelling body 10 repels the mountain fold portion of the filter 9, so that the filter 9 vibrates. The vibration of the filter 9 is propagated throughout the dust collection container 3. At this time, the fine dust adhering to the back surface of the filter 9 (the surface on the dust collection chamber 4 side) is shaken off by the suction of the vacuum cleaner due to the vibration and impact propagated to the dust collection container 3, and is collected in the dust collection chamber 4. Accumulate. Thereby, the filtration performance of the filter 9 can be revived.

Hereinafter, the control method of the vacuum cleaner in the present embodiment will be described with reference to FIG. 1A to FIG. 1C using FIG. FIG. 3 is a control block diagram according to the embodiment.

First, control in the dust collecting container 3 will be described.

As shown in FIG. 3, for example, the electric double layer capacitor 21 constituting the power storage unit 28 is connected to the power receiving terminal 20. The electric double layer capacitor 21 stores electrical energy supplied via 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 brought into conduction. Thereby, the dust removal motor 14 rotates with the electric energy stored in the electric double layer capacitor 21, and the dust removal operation is started.

Next, control in the vacuum cleaner body 1 will be described.

As shown in FIG. 3, the voltage detection unit 22 in the vacuum cleaner body 1 monitors the voltage of the electric double layer capacitor 21 through the power supply terminal 19 and the power reception terminal 20. At this time, if the voltage detected by the voltage detection unit 22 is less than a preset threshold value (for example, 2.1 V in the present embodiment), an operation signal is sent to the charge control unit 23. Note that the charge control unit 23 is configured by a semiconductor switch such as a transistor, for example.

Then, the charging unit 24 is controlled to be turned on / off according to the operation signal from the voltage detection unit 22. The charging unit 24 is a DC power source obtained by switching a commercial power source, 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 the present embodiment, For example, the output voltage is 2.1 V).

The operation of the vacuum cleaner configured as described above will be described with reference to FIG.

First, when the power cord of the electric vacuum cleaner is connected to a commercial power supply via an outlet and the electric power is supplied to the electric vacuum cleaner, the voltage detection unit 22 checks the voltage of the electric double layer capacitor 21. At this time, when the voltage of the electric double layer capacitor 21 is less than 2.1 V, the charging control unit 23 operates the charging unit 24 until the voltage of the electric double layer capacitor 21 becomes 2.1 V or more, so that the electric double layer The capacitor 21 is charged. By the charging control of the charging control unit 23, the voltage of the electric double layer capacitor 21 is maintained at 2.1 V or more when the commercial power supply is energized. On the other hand, when the vacuum cleaner is disconnected from the commercial power source, the voltage of the electric double layer capacitor 21 gradually decreases due to natural discharge, but is maintained at a voltage of about 2 V for a while.

Next, when the user starts the operation of the vacuum cleaner, the dust sucked from the suction nozzle is accumulated in the dust collecting chamber 4.

Therefore, in the following, the operation when the dust accumulated in the dust collection chamber 4 is discarded will be described with reference to FIG. FIG. 4 is a diagram illustrating a state of the dust collecting container at the time of throwing away dust in the same embodiment.

First, the user removes the dust collecting container 3 from the electric vacuum cleaner main body 1 as shown in FIG. Then, the removed dust collection container 3 is moved onto, for example, a trash can.

Next, when the lid 7 provided at the lower part of the dust collection chamber 4 of the dust collection container 3 is opened, most of the dust accumulated in the dust collection chamber 4 is discharged into the trash box. However, part of the dust adhering to the inner wall of the dust collection chamber 4 and the lid 7 remains in the dust collection chamber 4.

At this time, when the user turns on the dust removal switch 18 shown in FIG. 1C, the dust removal motor 14 is rotated by the electric energy stored in the electric double layer capacitor 21 which is the power storage unit 28. Accordingly, the entire dust collecting container 3 is vibrated around the filter 9 by the flip body 10 that reciprocates in accordance with the rotation of the dust removal motor 14. At this time, as shown in FIG. 4, vibration propagates not only to the filter 9 but also to the inner wall of the dust collection chamber 4 and the lid body 7. As a result, dust adhering to the inner wall of the dust collecting chamber 4 and the lid 7 is removed by vibration.

As described above, according to the present embodiment, the dust collection container 3 alone removed from the electric vacuum cleaner main body 1 can perform dust removal operation on a trash box or the like when throwing away trash. As a result, dust adhering to not only the filter 9 but also the inner wall of the dust collection chamber 4 and the lid 7 can be easily removed by the dust removal operation.

Further, according to the present embodiment, when the voltage of the electric double layer capacitor 21 used in the power storage unit 28 is monitored by the voltage detection unit 22 and sufficient electric energy is stored to perform the dust removal operation, The charging operation by the charging unit 24 is stopped. Thereby, since unnecessary electric power is not consumed, the vacuum cleaner excellent in energy saving property is realizable.

(Embodiment 2)
Hereinafter, the vacuum cleaner of the 2nd Embodiment of this invention is demonstrated using FIG. 5 and FIG. 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.

FIG. 5 is a perspective view of the electric vacuum cleaner according to Embodiment 2 of the present invention. FIG. 5 is a perspective view of the vacuum cleaner main body 1 with the dust collecting container 3 removed from the main body inlet A17 (front) of the vacuum cleaner main body 1.

As shown in FIG. 5, the vacuum cleaner of the present embodiment is provided with a detachable switch 26 on the partition wall 15 of the vacuum cleaner body 1. When the dust collecting container 3 is attached to the electric vacuum cleaner main body 1, the attachment / detachment switch 26 is turned on.

The operation of the vacuum cleaner configured as described above will be described with reference to FIG. FIG. 6 is a control block diagram in the same embodiment.

First, when the power supply cord of the vacuum cleaner is connected to a commercial power supply via an outlet, the vacuum cleaner is energized, and the attachment / detachment switch 26 is turned on, detection information such as on is input to the attachment / detachment detection unit 25. . When the detection information is input, the attachment / detachment detection unit 25 sends an operation signal to the timer 27 to start counting for a predetermined time (in this embodiment, for example, 30 seconds). Then, the charging control unit 23 is operated to start charging the electric double layer capacitor 21 that is the power storage unit 28 via the charging unit 24.

After 30 seconds have elapsed, upon receiving a signal from the timer 27 to the attachment / detachment detection unit 25, the attachment / detachment detection unit 25 stops the operation signal to the timer 27. Then, the charging control unit 23 stops the operation of the charging unit 24 and stops charging the electric double layer capacitor 21. In this embodiment, since charging of the electric double layer capacitor 21 is completed in about 25 seconds, the predetermined time is set to 30 seconds.

Then, by charging for 30 seconds, the voltage of the electric double layer capacitor 21 becomes 2.1 V that is the output voltage of the charging unit 24.

In addition, when the attachment / detachment switch 26 detects the removal and remounting of the dust container 3, it is assumed that the user has performed a dust removal operation using the electric energy of the electric double layer capacitor 21. Therefore, the attachment / detachment detection unit 25 performs the charging operation for 30 seconds again by the charging unit 24 via the timer 27 and the charging control unit 23.

As described above, according to the present embodiment, the use of the attachment / detachment detection unit 25 eliminates the need to constantly operate the charging unit 24 to charge the electric double layer capacitor 21. Thereby, when charging is unnecessary, the operation of the charging unit 24 can be stopped. As a result, a vacuum cleaner excellent in energy saving can be provided.

In addition, according to the present embodiment, compared to the voltage detection unit of the first embodiment, since it can be configured with a simple circuit by the detachable switch 26, the detachment detection unit 25, the timer 27, etc., the cost of the circuit can be reduced. realizable. That is, in the first embodiment, in order to monitor the voltage of the electric double layer capacitor 21, if a low voltage and low current signal line through contacts such as the power feeding terminal 19 and the power receiving terminal 20 is used, Since it is easily affected by the contact resistance, a complicated circuit is required to accurately detect the voltage of the electric double layer capacitor 21. Needless to say, charging of electric double layer capacitor 21 that is power storage unit 28 may be controlled by combining voltage detection unit 22 of the first embodiment and attachment / detachment detection unit 25 of the second embodiment. Thereby, energy saving property can be improved further.

In the first embodiment and the second embodiment, the example in which the dust collecting container 3 alone performs the dust removing operation when the user operates the dust removing switch 18 is described, but the present invention is not limited to this. For example, the same effect can be obtained even if the dust collecting container 3 alone is added to the vacuum cleaner that performs the dust removing operation of the filter at the time of energization or the operation of the vacuum cleaner which has become the mainstream these days. Needless to say. In other words, by performing a dust removal operation on the trash can, dust attached to the inner wall of the dust collection chamber 4 and the lid 7 that could not be removed in the past can be removed.

As described above, the vacuum cleaner of the present invention includes a dust collection container that collects dust attached to the main body of the vacuum cleaner, a dust removal unit that removes dust in the dust collection container, and a dust collection container. A power storage unit that stores the stored electrical energy, a charging unit that charges the power storage unit with electrical energy, and a dust removal operation unit that operates the dust removal unit using the electrical energy stored in the power storage unit.

This configuration can remove not only the filter surface of the dust removal unit, but also dust adhering to the inner wall and bottom surface of the dust collection chamber.

Moreover, the vacuum cleaner of the present invention includes a charge control unit that controls the charging unit and a voltage detection unit that detects a charging voltage of the power storage unit, and the charge control unit is based on detection information of the voltage detection unit. Control the charging part.

With this configuration, it is possible to charge the power storage unit by operating the charging unit only when the power storage unit needs to be charged. As a result, when charging is unnecessary, the operation of the charging unit is stopped and the power storage unit is not charged, so that a vacuum cleaner with excellent energy saving can be realized.

Further, the vacuum cleaner of the present invention includes an attachment / detachment detection unit that detects attachment / detachment of the main body of the vacuum cleaner, and the charge control unit controls the charging unit based on detection information from the attachment / detachment detection unit.

This configuration makes it possible to detect that the dust container has been removed from the main body of the vacuum cleaner and reattached. Further, when the attachment / detachment detection unit detects attachment / detachment of the dust collecting container, the charging control unit operates the charging unit again, and therefore it is not necessary to always operate the charging unit. As a result, when charging is unnecessary, the operation of the charging unit is stopped and the power storage unit is not charged, so that a vacuum cleaner with excellent energy saving can be realized.

Further, in the electric vacuum cleaner of the present invention, the power storage unit is composed of an electric double layer capacitor.

This configuration enables rapid charging with a large current, so that even a device that is energized only for a short time, such as a vacuum cleaner, can complete charging in an earlier time. Further, since the charge / discharge circuit can be simplified as compared with the secondary battery, the cost can be reduced.

The vacuum cleaner of the present invention can remove dust adhering not only to the filter surface of the dust removing unit but also to the inner wall and bottom surface of the dust collecting chamber, so it is applicable to various vacuum cleaners for home use, business use, and store use. it can.
