Description

  The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner having a dust removing means for removing dust collecting means.

  Conventionally, as this type of vacuum cleaner, pleats of substantially flat dust collecting means (pleated dust collecting filter) by moving an arm (dust removing means) driven by a filter dust removing motor equipped with a speed reduction mechanism There is one in which the vibration is given by hitting the portions sequentially and the fine dust adhering to the filter surface is shaken off to suppress the reduction in the suction performance (see, for example, Patent Document 1).

  There are many rechargeable vacuum cleaners that incorporate a rechargeable battery (secondary battery) in order to improve portability and convenience of the vacuum cleaner (see, for example, Patent Document 2).

  Among them, there is one in which a solar cell is mounted on a rechargeable vacuum cleaner with a limited operating time to increase the operating time as much as possible (see Patent Document 3).

  In addition, a generator unit is provided in a part of the intake path so that power is generated by the suction air generated by the electric blower in the cleaner body, and the user operates using the electric energy obtained by power generation. Some control signals sent from the operation unit to the electric blower are transmitted by wireless communication (see Patent Document 4).

Japanese Patent No. 4107171 JP 2006-75396 A JP 2003-204910 A JP 2002-78656 A

  However, in the configuration of the conventional vacuum cleaner as described in Patent Document 1, dust removal effect on the filter surface can be expected, but dust removed from the filter surface adheres to the inner wall and bottom surface of the dust collecting means. In other words, the dust separation property when the dust adhered to them was thrown away was not taken into consideration.

  Moreover, in the charge control of the conventional vacuum cleaner which mounts the rechargeable battery (secondary battery) as described in the said patent document 2, unless the user recharges the discharged secondary battery. The next time, there is a problem that the cleaning function using the power of the secondary battery cannot be used immediately.

  Moreover, in the conventional vacuum cleaner which mounted the solar cell in the rechargeable battery (secondary battery) as described in the said patent document 3, the storage battery arrange | positioned in a vacuum cleaner is charged and used also with a solar cell. Therefore, the user must wait for the recharged secondary battery to be recharged, and immediately use the cleaning function using the power of the secondary battery. There was a problem that we could not do it.

  Moreover, in the vacuum cleaner provided with the generator which generate | occur | produces electric power using the suction | inhalation wind as described in the said patent document 4, when a dust collecting means is removed from a vacuum cleaner main body, a suction | attraction force will not act and it will not generate | occur | produce electricity Therefore, there is a problem that the dust removing means in the dust collecting means cannot be operated.

  The present invention solves the above-mentioned conventional problems, and provides a vacuum cleaner with good usability that can remove not only dust on the filter surface but also dust attached to the inner wall and bottom surface of the dust collecting means when throwing away the dust. It is intended to be provided, and after the secondary battery is discharged, the main body of the vacuum cleaner is transported to the place where the commercial power supply is installed, or the plug of the power cord is plugged into the outlet for charging the secondary battery. When the user wants to use without the trouble of connecting, the secondary battery is already charged, and the vacuum cleaner can be used without the user being aware of the charging operation of the secondary battery. The purpose is to provide.

  In order to solve the above-described conventional problems, an electric vacuum cleaner of the present invention includes a vacuum cleaner body having an electric blower that generates suction air, and dust collection means detachably provided on the vacuum cleaner body, The dust collecting means stores a dust removing means for vibrating an inner wall or a component of the dust collecting means, a dust removing driving means for driving the dust removing means, and a first energy for storing electric energy for supplying power to the dust removing driving means. The first power storage means is charged with power storage means, a dust removal switch for electrically connecting the dust removal drive means and the first power storage means, a solar battery, and electric energy generated by the solar battery. The first charging means is provided with a first charging means, and the first charging means, regardless of whether or not commercial power is supplied to the vacuum cleaner, One power storage means Able to charge.

  For example, when the user finishes cleaning with a vacuum cleaner, removes the plug from the outlet, removes the dust collecting means from the vacuum cleaner body, takes it over the trash can and discharges the dust in the dust collecting means, When the dust removal switch is pressed, the first power storage means and the dust removal drive means are electrically connected, and the dust removal drive means moves the dust removal means to vibrate the inner wall and components of the dust collection 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 oscillating operation, the first power storage means is discharged and the electric energy is lost.

  Even if 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, but the first charging means is a solar that always generates power from sunlight or light from the room light. The first energy storage means can be charged with the electric energy of the battery. As a result, if the user tries to clean the next time, for example, the next day, he / she will be worried about the state of the dust collecting means before starting the cleaning, and remove the dust collecting means from the vacuum cleaner main body. Even when the dust removal switch is pressed to discharge the adhered dust inside, the first power storage means is already charged. Is possible.

  In this way, since the first charging means always charges the first power storage means with the electric energy of the solar battery that generates power by sunlight or light from the room light, the user can charge the first power storage means. It is possible to provide a highly usable vacuum cleaner that can use the dust removing function of the dust collecting means when desired to use without being aware of the operation and the charged state.

The vacuum cleaner according to the present invention automatically dusts not only on the filter surface of the dust collecting means but also on the inner wall and bottom surface of the dust collecting means on the spot when the dust in the dust collecting means removed from the vacuum cleaner body is discarded. Can be removed. In addition, even when there is no power supply from a commercial power source, the user can charge the first power storage means by charging the first power storage means with the electric energy of the solar battery that generates power by sunlight or light from the room light. It is possible to provide a highly usable vacuum cleaner that can utilize the dust removing function of the dust collecting means when desired to use without being aware of the operation and the charged state.

  A first invention includes a vacuum cleaner body having an electric blower that generates suction air, and dust collection means detachably provided on the vacuum cleaner body. The dust collection means includes an inner wall of the dust collection means, Dust removal means for vibrating the component, dust removal drive means for driving the dust removal means, first power storage means for storing electrical energy to supply power to the dust removal drive means, the dust removal drive means, and the first A dust removal switch for electrically connecting the power storage means, a solar cell, and a first charging means for charging the first power storage means with the electric energy generated by the solar battery. Regardless of whether or not commercial power is supplied to the vacuum cleaner, the first charging means can charge the first power storage means with the electric energy of the solar cell that generates power by sunlight or light from the room light.

  For example, when the user finishes cleaning with a vacuum cleaner, removes the plug from the outlet, removes the dust collecting means from the vacuum cleaner body, takes it over the trash can and discharges the dust in the dust collecting means, When the dust removal switch is pressed, the first power storage means and the dust removal drive means are electrically connected, and the dust removal drive means moves the dust removal means to vibrate the inner wall and components of the dust collection 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 oscillating operation, the first power storage means is discharged and the electric energy is lost. Even if 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, but the first charging means is a solar that always generates power from sunlight or light from the room light. The first energy storage means can be charged with the electric energy of the battery.

  As a result, if the user tries to clean the next time, for example, the next day, he / she will be worried about the state of the dust collecting means before starting the cleaning, and remove the dust collecting means from the vacuum cleaner main body. Even when the dust removal switch is pressed to discharge the adhered dust inside, the first power storage means is already charged. Is possible.

  In this way, since the first charging means always charges the first power storage means with the electric energy of the solar battery that generates power by sunlight or light from the room light, the user can charge the first power storage means. It is possible to provide a highly usable vacuum cleaner that can use the dust removing function of the dust collecting means when desired to use without being aware of the operation and the charged state.

In the second aspect of the invention, in particular, a charging part that is electrically connected to the first power storage means is disposed in the dust collecting means of the vacuum cleaner body of the first aspect of the invention. Is a second power storage means, a second charge means for controlling charging of the first power storage means and the second power storage means, and a first voltage for detecting a charge voltage of the first power storage means The detection means and a circuit for charging the second power storage means with the electric energy from the solar battery or a circuit for charging the first power storage means with the electric energy stored in the second power storage means are selected. Charging and discharging circuit selection means, wherein the second charging means is a circuit for charging the second power storage means or the first power storage means according to the output voltage of the first voltage detection means. The charging circuit is switched by the charging / discharging circuit selecting means, and the second charging is performed. Stage, it is possible to determine the charge voltage (state) of the first storage means by the output voltage of the first voltage detecting means. When the second charging unit determines that the charging voltage of the first power storage unit is high (that is, the first power storage unit is in a fully charged state), the second charging unit converts the electric energy generated by the solar cell to the first power storage unit. The charging / discharging circuit selection means selects a circuit that charges the second power storage means so that the second power storage means is stored in the second power storage means so that the second power storage means is stored in the second power storage means. Charge. When the second charging means determines that the charging voltage of the first power storage means is low (that is, the charge capacity of the first power storage means is insufficient), the charge / discharge circuit selection means, Select the circuit that charges the first power storage means with the electrical energy stored in the second power storage means, and in combination with the solar cell, the electrical energy stored in the second power storage means, The first power storage means is charged.

  Thus, when the first power storage means is fully charged, the first energy storage means is charged with the electrical energy generated by the solar battery, and the second power storage means is also charged to store the electrical energy. To do. When the charging capacity of the first power storage means is insufficient, the user uses the dust removal function by charging the first power storage means with the electrical energy stored in the second power storage means. When you want to, you can eliminate the state of being unable to use due to insufficient charging.

  In this way, the user can use the dust removing function of the dust collecting means when he / she wants to use it without being aware of the charging operation and the charged state of the first power storage means. In addition, since only the electric energy generated by the solar cell is used without using the electric energy from the commercial power source, it is possible to provide a highly usable vacuum cleaner that is excellent in energy saving.

  According to a third aspect of the invention, in particular, the housing part of the second aspect of the invention is a charging part that is electrically connected to the solar cell, and the cleaner body is a second voltage detector that detects the power generation voltage of the solar cell. The second charging means includes a circuit for charging the second power storage means or the first power storage means in accordance with the output voltages of the second voltage detection means and the first voltage detection means. The charging / discharging circuit selection means switches the circuit to be charged, and the second charging means can determine the charging voltage (state) of the first power storage means based on the output voltage of the first voltage detection means. At the same time, the generated voltage of the solar cell can be determined from the output voltage of the second voltage detecting means. When the second charging unit determines that the power generation voltage of the solar cell is high (that is, the amount of sunlight or room light is sufficient and the solar cell generates sufficient electric energy), A circuit for charging the second power storage means by the charge / discharge circuit selection means so that the electric energy generated by the solar cell is stored not only in the first power storage means but also in the second power storage means. Select and also charge the second power storage means. Further, when the second charging means has a low power generation voltage of the solar cell (that is, the amount of sunlight or room light is insufficient and the electric energy generated by the solar cell is insufficient). When the determination is made, the charging / discharging circuit selection means selects a circuit that charges the first power storage means with the electrical energy stored in the second power storage means, and the second battery instead of the solar battery is selected. Electric energy stored in the power storage means is charged in the first power storage means.

Thus, when the electrical energy generated by the solar cell is sufficient, the first power storage means is charged and the second power storage means is also charged to store the electrical energy. When the electric energy generated by the solar cell is insufficient, the user wants to use the dust removal function by charging the first power storage means with the electric energy stored in the second power storage means. Sometimes it is possible to eliminate the state of being unable to use due to insufficient charging.

  In this way, the user can use the dust removing function of the dust collecting means when he / she wants to use it without being aware of the charging operation and the charged state of the first power storage means. In addition, since only the electric energy generated by the solar cell is used without using the electric energy from the commercial power source, it is possible to provide a highly usable vacuum cleaner that is excellent in energy saving.

  According to a fourth aspect of the present invention, in particular, the electric vacuum cleaner according to any one of the first to third aspects includes a wind power generation unit that generates power using wind power in the intake path or the exhaust path, and the electric power generated by the wind power generation unit. A third charging means for charging energy to the first power storage means is provided, and when the user starts cleaning, the electric energy generated by the solar cell is insufficient and the first power storage means is charged. Even if the voltage is low, the user cleans the wind power generated in the air intake path of the vacuum cleaner being cleaned, the wind power generating means is generated, and the third charging means is Since the electric energy can be charged in the first power storage means, the dust removal function of the dust collecting means can be used when the user finishes cleaning.

  In this way, the electric energy from the commercial power source is not directly used for charging the first power storage means, but using the wind force in the intake path generated by the user performing the cleaning operation, Since electric energy is generated by wind power generation means and used as electric energy for the dust removal function, it is possible to provide a vacuum cleaner with excellent energy saving and good usability.

  In the fifth invention, in particular, the wind power generation means of the fourth invention is arranged in the dust collecting means, and the electric path is completed in the dust collecting means. Can be simplified. For example, when the wind power generation means is provided in the hand operation section, the electrical path passes through the hose, and a connection section (electrical contact) is required between the hose and the cleaner body. And an electrical path passes through the inside of a cleaner body, and a connection part (electrical contact) is needed also between a cleaning body and dust collecting means.

  However, since the wind power generation means is disposed in the dust collection means, the connection portion (electrical contact) is not required and can be simplified, so that the cost of the vacuum cleaner is reduced and the usability is good. A vacuum cleaner can be provided.

  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.

  In FIG. 2, the partition wall 15 of the cleaner body 1 serves as a housing portion that houses the dust collection container 3, and partitions the cleaner body 1 and the dust collection container 3. A lattice-shaped partition wall opening 16 communicating with the two suction portions is provided. Further, a main body inlet B14 is provided at a side portion of the partition wall 15 and communicates with the main body inlet A13 via a communication path (not shown) inside the cleaner body 1.

  The dust collecting container 3 is provided with a filter unit 31 as a filtering means that is detachably attached and a dust collecting chamber 32 for accumulating dust. When the dust collecting container 3 is attached to the cleaner body 1 Is provided with a dust collection container inlet 33 that communicates with the main body inlet B14 of the cleaner body 1 and guides the suction air to the dust collection chamber 32 (see FIG. 2C).

  Then, the suction air from which dust is removed in the dust collecting container 3 passes through the partition opening 16, passes through the electric blower 2, and is discharged from the exhaust port 9 provided at the rear of the cleaner body 1. The In addition, a dust removal switch 34 is configured in the upper part of the dust collecting container 3, and a dust removal means 35 described later is operated by a user operation. A lid body 36 is attached to the bottom of the dust collecting container 3 so as to be freely opened and closed. By opening the lid body 36, dust accumulated in the dust collection chamber 32 can be discharged to the outside.

  The partition wall 15 of the vacuum cleaner main body 1 is provided with a power supply terminal 17 provided in the dust collecting container 3 and serving as a charging unit for electrical connection with an electric double layer capacitor S37 described later. A power receiving terminal 38 paired with the terminal 17 is provided in the dust collecting container 3. These terminals are configured to be electrically connected when the dust collecting container 3 is attached to the cleaner body 1.

  Next, the internal configuration of the dust collecting container 3 will be described with reference to FIG. In FIG. 3, the filter unit 31 includes a frame body 40, a filter 41 that is pleated and provided on the frame body 40, and a flip body 42 that is slidably provided in the lateral direction with the pleats in the vertical direction. The dust removal gear 43 is provided rotatably with respect to the filter unit 31, and the dust removal connecting rod 44 connects the outer periphery of the dust removal gear 43 and a part of the flip body 42. Further, on the surface of the flip body 42 that faces the filter 41, a projection (not shown) that abuts each mountain fold 41a of the pleated filter 41 is provided.

  The fixed rod 45 is fixed to the frame body 40, and a rotating shaft (not shown) of the dust removing gear 43 is rotatably supported by the fixed rod 45. The operation direction of the flip body 42 is configured to restrict the pleats to operate in the horizontal direction with the vertical direction.

  The dust removing gear 43 side of the dust removing connecting rod 44 has a tooth shape that meshes with the dust removing gear 43. When the dust removing gear 43 rotates in the forward or reverse direction, the dust removing connecting rod 44 slides and plays. The body 42 is configured to move in the left-right direction.

  A dust removal motor 46 that is provided with a gear 46 a that meshes with the dust removal gear 43 and that serves as a dust removal drive unit is connected to the dust removal gear 43, and this dust removal motor 46 rotates to transmit power to the dust removal gear 43.

  With the above configuration, when the dust removal motor 46 is rotated, the dust removal gear 43 rotates, and the flip body 42 connected via the dust removal connecting rod 44 reciprocates left and right, while the protrusions provided on the flip body 42 are interposed therebetween. 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. As a result of this vibration and impact, fine dust adhering to the back surface of the filter 41 (the surface on the dust collection chamber 32 side) is screened out and dropped and collected in the dust collection chamber 32, and the filtration performance of the filter 41 is restored. It has become.

  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 dust collecting container 3, an electric double layer capacitor S37 as a first power storage means is provided.

  The solar cell 28 is a power device that uses the photovoltaic effect to directly convert light energy such as sunlight and room light into electric power. The electric energy generated by the solar cell 28 is charged and stored in the electric double layer capacitor S37 through the first charging means 24, here the diode.

  When the light energy such as sunlight or room light is weak and the power generation capacity of the solar cell 28 is low, the diode as the first charging means 24 causes the electric energy stored in the electric double layer capacitor S37 to flow backward and be consumed by the solar cell 28. Not to be. Moreover, the solar cell 28 is provided in the place where sunlight or room light hits well in the outline of the dust collecting container 3 (see, for example, FIG. 1).

  The dust removal switch 34 is connected between the electric double layer capacitor S37 and the dust removal motor 46. When the dust removal switch 34 is turned on, the electric double layer capacitor S37 and the dust removal motor 46 are brought into conduction, and the electric double layer capacitor The dust removal motor 46 is rotationally driven by the electrical energy of S37.

  Next, the cleaner body 1 side surrounded by a dotted line will be described. The vacuum cleaner main body 1 is supplied with power from the commercial power source 12 by inserting the plug 11 (FIG. 1) of the power cord 10 into an outlet (not shown). The vacuum cleaner main body 1 includes a driving unit 21 configured by a bidirectional thyristor for driving the electric blower 2 and a control unit 20 configured by a microcomputer for controlling the driving unit 21. The control means 20 receives the operation information from the hand operation unit 5 by the user and controls the operation of the vacuum cleaner.

  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 by suction force from a horizontally long opening (not shown) on the lower surface of the suction tool 8 and sucked into the dust collecting container 3 in the cleaner body 1 through the extension pipe 7 and the hose 6. And 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.

  When the cleaning is finished, 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 discard the dust collected in the dust collection container 3, the user removes the dust collection container 3 from the cleaner body 1, moves it to the top of the trash box as shown in FIG. The lid 36 is opened, and the dust accumulated in the dust collecting chamber 32 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 shown in FIG. 2, the dust removal motor 46 in FIG. 3 is rotated by the electric energy stored in the electric double layer capacitor S <b> 37 built in the dust collecting container 3. The entire dust collection container 3 vibrates around the filter 41 by the operation of the body 42, and the vibration propagates not only to the filter 41 but also to the inner wall of the dust collection chamber 32 and the lid 36 as shown in FIG. Can be further peeled off and removed.

  After the dust in the dust collecting container 3 is discarded, the charge capacity of the electric double layer capacitor S37 in the dust collecting container 3 is returned to the vacuum cleaner main body 1 in an empty state by the vibration operation, and the user uses the electric vacuum cleaner. Cleared up. Since the solar battery 28 of the vacuum cleaner in the present embodiment is provided in a place where the sunlight or room light hits well on the outer periphery of the dust collecting container 3, whether or not the user is cleaning, Even if the dust collecting container 3 is not attached to the cleaner body 1, power is always generated as long as the solar cell 28 is exposed to light. The generated electric energy is charged in the empty electric double layer capacitor S37 through the first charging means 24.

  Thus, for example, when the user cleans the next day and presses the dust removal switch 34 to remove the dust collecting container 3 from the cleaner body 1 and discharge the dust again after cleaning, Since the multilayer capacitor S37 is already charged, it is possible to perform a dust removal operation in the dust collecting container 3.

  As described above, when the dust in the dust collection container 3 is discarded, the dust attached to the inner wall and the bottom surface of the dust collection chamber 32 can be automatically removed. Moreover, in order to charge the discharged electric double layer capacitor S37 of the dust collecting container 3, the user has to carry the cleaner body 1 to the place where the commercial power supply is installed or connect the plug 11 of the power cord 10 to the outlet. The first charging means 24 automatically charges the electric double layer capacitor S37 with the electric energy generated by the solar cell 28 while the user is not using the dust removal function of the dust collecting container 3 without applying Therefore, when the user wants to use, the electric double layer capacitor S37 can be charged. Thereby, the user can use the dust removing function of the dust collecting container 3 at any time without being aware of the charging operation and the charging state of the electric double layer capacitor S37.

(Embodiment 2)
FIG. 6 is a control block diagram of the electric vacuum cleaner according to the second embodiment of the present invention. In addition, about the same component as the vacuum cleaner in the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The control method of the vacuum cleaner in this Embodiment is demonstrated using FIG. The vacuum cleaner main body 1 and the dust collecting container 3 surrounded by a dotted line are electrically connected by the power supply terminal 17 and the power reception terminal 38. The vacuum cleaner main body 1 includes an electric double layer capacitor H23 as the second power storage means.

  The electric double layer condenser H23 in the vacuum cleaner body 1 is electrically connected to the electric double layer capacitor S37 in the dust collecting container 3 via the charge / discharge circuit selection means 26.

  The charge / discharge circuit selection means 26 is composed of a switch for selecting two circuits. If the switch of the charge / discharge circuit selection means 26 selects the upper contact 26a, the electric energy stored in the electric double layer capacitor H23 is charged in the electric double layer capacitor S37.

Here, in the diode 29, when the electric energy stored in the electric double layer condenser H23 is small and the charging voltage is low, the electric energy stored in the electric double layer capacitor S37 on the dust collecting container 3 side flows backward, and the electric double layer condenser It is prevented from being consumed by H23.

  Moreover, if the switch which is the charge / discharge circuit selection means 26 selects the lower contact 26b, the electric energy generated by the solar cell 28 is charged not only in the electric double layer capacitor S37 but also in the electric double layer capacitor H23. Can do.

  Then, the first voltage detection means 27 detects the charging voltage of the electric double layer capacitor S37 in the dust collecting container 3. The second voltage detection means 25 detects the power generation voltage of the solar cell 28 installed outside the dust container 3. The second charging unit 22 is a circuit for charging the electric energy from the solar cell 28 to the electric double layer condenser H23 according to the detection information from the first voltage detecting unit 27 and the second voltage detecting unit 25. The charge / discharge circuit selection means 26 switches between the circuit for charging the electric energy stored in the electric double layer capacitor H23 to the electric double layer capacitor S37 or the circuit unselected.

  Here, the second charging means 22, the first voltage detecting means 27, and the second voltage detecting means 25 are operated by the electric energy stored in the electric double layer condenser H23.

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

  For example, immediately after the user uses the dust removal function, the charging voltage of the electric double layer capacitor S37 detected by the first voltage detection means 27 is low and is empty (for example, less than 2.1 V).

  At this time, when the power generation voltage of the solar cell 28 detected by the second voltage detection means 25 is sufficient (for example, 3.5 V or more), the second charging means 22 is the charge / discharge circuit selection means 26, Select circuit unselected. Thereby, all the electric energy generated by the solar cell 28 can be charged into the electric double layer capacitor S37 via the first charging means 24.

  Then, if the charging of the electric double layer capacitor S37 proceeds and the charging voltage of the electric double layer capacitor S37 detected by the first voltage detecting means 27 becomes high (for example, 3.1 V or more in the fully charged state), The second charging means 22 selects a lower contact 26b with a switch which is a charging / discharging circuit selection means 26, and forms a circuit for charging the electric energy from the solar cell 28 also to the electric double layer condenser H23.

  By doing so, electric energy more than necessary (more than the capacity of the electric double layer capacitor S37) generated by the solar cell 28 can be charged and stored in the electric double layer capacitor H23.

  For example, if the user uses the dust removal function again, the charging voltage of the electric double layer capacitor S37 detected by the first voltage detecting means 27 is low and becomes empty. At this time, if the generated voltage of the solar cell 28 detected by the second voltage detection means 25 is insufficient (for example, less than 2.1 V), charging from the solar cell 28 to the electric double layer capacitor S37 cannot be expected. . Therefore, if the second charging means 22 selects the upper contact 26a with the switch which is the charging / discharging circuit selection means 26, the electric energy charged and stored in the electric double layer condenser H23 so far, The electric double layer capacitor S37 can be charged again.

As described above, when the electric energy generated by the solar cell 28 is sufficient, the electric double layer capacitor S37 is charged and the electric double layer capacitor H23 is also charged to store the electric energy. When the electric energy generated by the solar cell 28 is insufficient, the user uses the dust removal function by charging the electric double layer capacitor S37 with the electric energy stored in the electric double layer condenser H23. When you want to, you can eliminate the state of being unable to use due to insufficient charging.

  Thus, the user can use the dust removal function of the dust collecting container 3 when he / she wants to use it without being aware of the charging operation and the charging state of the electric double layer capacitor S37. In addition, since only the electric energy generated by the solar cell 28 is used without using the electric energy from the commercial power supply 12, it is possible to provide a vacuum cleaner with good usability and excellent energy saving.

  Here, although the 2nd charging means 22 has shown the form which switches the charging / discharging circuit selection means 26 according to the detection voltage of the 1st voltage detection means 27 and the 2nd voltage detection means 25, the 1st The electric energy from the solar cell 28 is charged to the electric double layer condenser H23 or the electric energy stored in the electric double layer condenser H23 is charged to the electric double layer capacitor S37 only by the information from the voltage detection means 27 of If one of the circuits to be selected is selected and switched by the charge / discharge circuit selection means 26, the circuit can be simplified, the cost of the vacuum cleaner can be reduced, and the energy consumption can be improved. A good vacuum cleaner can be provided.

(Embodiment 3)
FIG. 7 is a side sectional view of the dust collecting container of the electric vacuum cleaner according to the third embodiment of the present invention, and FIG. 8 is a control block diagram of the electric vacuum cleaner. Note that the same components as those in the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.

  7 and 8, the electric vacuum cleaner according to the present embodiment generates electric power by rotating the rotating fan 48 provided in the dust collecting chamber 32 in the dust collecting container 3 and the rotating fan 48 by the wind force. Wind power generation means 47 comprising a machine main body 49 is provided. The wind power generation means 47 is electrically connected to the solar cell 28 in parallel.

  The third charging means 50 is constituted by a diode or the like, and charges and stores the electric energy generated by the wind power generation means 47 in the electric double layer capacitor S37. Here, the diode which is the third charging unit 50 has a low power generation capability of the wind power generation unit 47, and when the generated voltage is low, the electric energy stored in the electric double layer capacitor S37 flows backward and is not consumed by the wind power generation unit 47. I am doing so.

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

  When the user starts cleaning, a complicated wind flow is generated in the dust collection chamber 32 by the suction air generated by the electric blower 2. For example, in FIG. 7, a swirling flow as indicated by an elliptical arrow is generated at the outermost periphery in the dust collection chamber 32. The swirling flow of the suction air contains dust, and while rotating, the airflow and dust are centrifuged, and the dust accumulates in the lower part of the dust collecting chamber 32. The clean air in which dust is collected passes through the filter 41 of the dust collecting container 3, passes through the partition wall opening 16 of the cleaner body 1 shown in FIG. 2, passes through the electric blower 2, and is discharged into the atmosphere from the exhaust port 9. Released into.

  The wind power generation means 47 uses the power of the swirling flow (suction air) generated in the dust collecting container 3 to rotate the rotary fan 48 and generate electric energy by the generator main body 49. The generated electric energy is stored in the electric double layer capacitor S37 by the third charging means 50 as shown in FIG.

  That is, when the user performs cleaning, the suction air generated by the electric blower 2 is used not only for the cleaning operation but also for power generation.

  Even if the electric energy generated by the solar cell 28 is insufficient, or even when the electric double layer capacitor S37 or the electric double layer condenser H23 is undercharged, the user cleans it. Thus, during the cleaning, the wind power generation means 47 generates power using the force of the suction wind generated by the electric blower 2, and the third charging means 50 charges the electric double layer capacitor S37 with the electric energy. Therefore, when the user finishes cleaning, the dust removal function of the dust collecting means 3 can be used.

  In this way, the electric energy from the commercial power supply 12 is not directly used for charging the electric double layer capacitor S37, but the user uses the force of the suction wind generated by the cleaning operation to generate wind power. Since electric energy is generated by the power generation means 47 and used as electric energy for the dust removal function, a vacuum cleaner with good energy saving and good usability can be provided.

  Here, an example in which the wind power generation means 47 is provided in the intake path, in particular, the dust collecting container 3 has been described, but the wind power generation means 47 may be provided in an exhaust path (not shown) in the cleaner body 1.

  For example, FIG. 9 shows a control block diagram in the case where the wind power generation means 47 and the third charging means 50 are provided in the exhaust path in the cleaner body 1.

  The electric energy generated by the wind power generation means 47 is charged and stored in the electric double layer condenser H23 by the third charging means 50. As in the second embodiment, the stored electrical energy can be charged into the electric double layer capacitor S37, thereby eliminating the state where the user cannot use due to insufficient charging when he / she wants to use the dust removal function.

  Thus, the user can use the dust removal function of the dust collecting container 3 when he / she wants to use it without being aware of the charging operation and the charging state of the electric double layer capacitor S37. Moreover, since the wind power generation means 47 uses the electric energy to generate without using the electric energy from the commercial power source 12, it is excellent in energy saving.

  Further, since the dust is removed from the dust collection container 3 in the exhaust path compared to the intake path, the flowing wind is clean. For this reason, the wind power generation means 47 does not require the same dustproof measures as when installed in the intake passage. Therefore, the wind power generation means 47 can be simplified, and the power generation performance degradation and the failure probability due to the adhesion of dust are low. Therefore, the vacuum cleaner is highly reliable and has good usability while realizing low cost. Can be provided.

  In the above embodiment, the first power storage unit and the second power storage unit are each configured by an electric double layer capacitor. However, the first power storage unit and the second power storage unit are realized by other power storage units (for example, a secondary battery). May be.

  As described above, the electric vacuum cleaner according to the present invention uses the power generation means such as a solar battery and wind power generation and the electric energy to store the power in the power storage means without the supply of commercial power. Sometimes dust adhering to the inner wall and bottom of the dust collecting means can be automatically and efficiently removed by vibration dust removal, so it can be widely applied to various household and commercial vacuum cleaners equipped with a dust removal function.
