Description

  The present invention relates to a vacuum cleaner in which a filter of a filtering type is disposed on the suction side of an electric blower.

  When the filter that suppresses the suction of dust into the electric blower of the vacuum cleaner is clogged, the filter is washed with water and regenerated, or maintenance such as replacement with a new filter is required. As the resistance increases, the force for sucking in the dust-containing air decreases and the cleaning performance decreases.

  In particular, in vacuum cleaners having a dust separation unit that uses the inertial force of dust, such as a cyclone type, which has been developed in recent years, due to the performance of the dust separation unit, there is a need for a fine filter for a filter disposed between the separation unit and the electric blower. The present inventors have clarified that the amount of dust attached is large and the dust separation action using the inertial force of the dust tends to be reduced based on this. For this reason, in this kind of vacuum cleaner, it is requested | required to improve the clogging of a filter at an early stage.

  2. Description of the Related Art Conventionally, a filter equipped with a dust removing device to improve filter clogging is known (for example, see Patent Document 1).

In the electric vacuum cleaner of Patent Document 1, dust is removed from the wave shape filter by utilizing the rotation of a cord reel in which a power cord taken in and out of the main body is wound and fed out. Specifically, a leaf spring net dust remover with an integrated receiver is attached to the back of the filter. By rotating the cam in conjunction with the cord reel, the filter is subjected to impact vibration by a vibrating net dust remover. For this reason, the filter can always be removed by the cord reel operation before and after cleaning.
JP-B-60-49495 (Field of Use of Invention, column 8, lines 32-44, column 11, lines 9-13, column 12, columns 31-13, column 8, lines 1 to 4) (Figure)

  Furthermore, when the dust trapped by the filter is left in a trapped state for a long period of time, for example, for at least one day and night, it may solidify by sucking moisture in the air in the cleaner body. In particular, when dirt is mixed, the trapped dust tends to harden. As the solidification of the dust progresses, it becomes more difficult to remove the hardened dust from the filter. Therefore, it is required to improve the clogging of the filter filter included in the vacuum cleaner at an early stage.

  On the other hand, in the inertial separation type vacuum cleaner that separates dust from the suction air by a cyclone type or the like, the amount of fine dust adhering to the filter tends to be large as described above. Although it is preferable that automatic dust removal can be performed as early as possible at the stage where it does not set, a vacuum cleaner that satisfies these requirements has not been provided.

  In Patent Document 1, the rotation of the cord reel is used to operate the dust removing device. For this reason, a vacuum cleaner that does not include a cord reel, that is, a cordless vacuum cleaner in which a secondary battery is built in a vacuum cleaner body and an electric blower is driven by the power of the battery is disclosed in Patent Document 1. Cannot be applied and new measures are desired.

  The problem to be solved by the present invention is to obtain a vacuum cleaner capable of automatically removing dust from a filter immediately after cleaning using an operation for charging.

  In order to solve the above-mentioned problems, the present invention provides a filter body for filtering dust and trapping dust in a vacuum cleaner body incorporating an electric blower and a secondary battery for supplying power to the blower, and this filter. The secondary battery in the vacuum cleaner main body installed on the charging stand or the main body of the vacuum cleaner, which is provided with a dust removing means for removing dust by vibration and is always connected to the power supply and used to charge the secondary battery A control means having a dust removal control unit for operating the dust removal means before the start of charging is provided, and this control means is used for dust removal of the secondary battery based on the fact that the main body of the vacuum cleaner is installed on the charging stand. The dust removing means is operated by supplying it to the electric motor.

  The fact that the main body of the vacuum cleaner that has been shut down is installed on the charging stand means that the secondary battery can be charged as soon as cleaning is finished and the main body of the vacuum cleaner is removed, or the cleaning is interrupted. Since it is time to charge the secondary battery, in the present invention in which the dust removal means is operated by the control means based on this, for example, every time cleaning is completed, the dust trapped in the filter is not completely solidified. The filter can be vibrated by dust removing means to remove dust early.

Further, in order to solve the above-described problems, an air blower, a secondary battery that supplies power to the air blower, and a vacuum cleaner body that incorporates a charging device that charges the battery are used to filter the suction air and capture dust. A filter for removing dust by vibrating the filter, and a control means, respectively, and the control means removes the dust removal means based on the connection of the power plug connected to the charging device to the power source. with operating, by the control means, so that to operate the dust removal means prior charging start of the secondary battery in the cleaner body in a state where the power plug is connected to a power source.

  The connection of the power plug to the power supply is based on the fact that the cleaning is completed and the secondary battery can be charged, or the cleaning is interrupted and the secondary battery needs to be charged. In the present invention in which the dust removal means is operated by the control means, the dust can be vibrated by the dust removal means and the dust can be quickly removed before the dust trapped by the filter is hardened.

  In these inventions, it is preferable that the control means stops the operation of the dust removing means when the electric blower is driven during the operation of the dust removing means.

  According to the present invention, an electric vacuum cleaner capable of automatically removing dust from a filter by supplying electric power of a secondary battery to a dusting motor before starting charging after cleaning using an operation for charging. Can provide a machine.

  As shown in FIG. 2, the cleaner body 2 is configured, for example, in a canister shape, and can be attached to and detached from a main body case 23 to which a front wheel 21 and a rear wheel 22 running on a surface to be cleaned are attached, and the front side of the case 23. And a third filter 30 that is detachably attached to the dust collection case 24. The main body case 23 has a dust collection case receiver 23b protruding forward at its lower end, and a dust collection case 24 is detachably mounted on the receiver 23b.

  In the main body case 23, an electric blower 25, a secondary battery 26 serving as a power source for the blower 25, a dust removing means such as a dust removing device 27, a control means such as a control device 28, and the like are provided. A pair of power receiving terminals 29 (see FIGS. 1 and 5) connected to the output terminal 11a when placed on the charging stand 1 are provided.

  The electric blower 25 driven by the electric power discharged from the secondary battery 26 is built in the main body case 23 with the suction port 25a facing forward, for example, and the air discharged from the exhaust hole 25b of the blower 25 is The exhaust case 23c (see FIG. 1) provided in the main body case 23 is discharged out of the main body case 23. For example, the secondary battery 26 made of a nickel metal hydride battery or the like is disposed below the electric blower 25.

  The dust removing device 27 is an electric drive type driven by electric energy, and includes a support frame 31 made of a synthetic resin having air permeability, a dust remover 32, a dust removing motor 33, and a drive gear 34. .

  Specifically, as shown in FIG. 2, the support frame 31 is disposed between a filter 30 described later and a suction port 25 a of the electric blower 25. The frame 31 has a large number of air holes 31a facing the back surface (downstream surface) of the filter 30, and has a shaft portion 31b protruding to the front side (upstream side).

  As shown in FIG. 3, the dust remover 32 has a ring shape, and a plurality of ribs 32 a extending in the radial direction are provided on the inside thereof, and an annular rib 32 b that intersects with the ribs 32 a is provided. Therefore, the dust remover 32 can be ventilated. Further, the dust remover 32 has a dust removal convex portion 32 c protruding toward the filter 30 and is formed by providing a gear portion 32 d on the outer peripheral portion. The dust remover 32 is disposed between the support frame 31 and the filter 30 with the shaft fitting portion 32e at the center thereof being rotatably fitted to the shaft portion 31b.

  A small electric motor is used for the dust motor 33. The electric motor 33 is attached to, for example, a motor arrangement portion 31 c formed integrally with the support frame 31 and is arranged in the vicinity of the gear portion 32 d of the dust remover 32. A gear mounting shaft 35 is fitted on the outer periphery of the rotating shaft 33 a of the electric motor 33, and a drive gear 34 is mounted on the shaft 35. The drive gear 34 is much smaller in diameter than the gear portion 32d of the dust remover 32, and is engaged with the gear portion 32d. Therefore, when the electric motor 33 is energized, the dust remover 32 is decelerated and rotated through gear transmission. The electric motor 33 is appropriately supplied with electric power from the secondary battery 26.

  The dust removing device 27 having the above configuration is unitized with the support frame 31 as a reference, and can be easily incorporated into the main body case 23. 2 indicates a protective cover, which is formed integrally with the support frame 31, and is a part of the toothed portion of the drive gear 34 (excluding the meshing portion with the gear portion 32d). ) For safety.

  The power receiving terminal 29 protrudes into a recess 23d formed in the end wall 23a of the main body case 23, and is attached to the end wall 23a. The power receiving terminal 29 is electrically connected to the secondary battery 26. For this reason, the secondary battery 26 can be charged at the same time when the cleaner body 2 is placed on the charging stand 1.

  The control device 28 is configured by mounting a microprocessor and other circuit components on a circuit board. For example, the control device 28 is arranged below the electric blower 25 and behind the secondary battery 26. As shown in FIG. 5, the control device 28 has a function of controlling the drive circuit 36 to selectively supply the electric power of the secondary battery 26 to the electric blower 25 or the dust removal electric motor 33.

  Furthermore, the control device 28 has a dust removal control unit 28a. This control unit 28a has a function of operating the dust removing device 27 before starting the charging of the secondary battery 26 in the cleaner body 2 installed on the charging stand 1, and the electric blower 25 during the charging of the secondary battery 26. It has a function of cutting off the power supply to the dust removal motor 33 when electric power is supplied. The start of charging the secondary battery 26 can be detected by the control device 28 by an input from the signal line 37 shown in FIG. 5, and the power supply to the electric blower 25 can be detected by the control device 28 by an input from the operation unit 20.

  As shown in FIG. 2, the dust collection case 24 has a container part 24 a whose rear surface is opened in a posture when the vacuum cleaner is in use, and the container part 24 a includes a lower dust storage chamber 41 and an upper part. The partition wall 43 is divided into a negative pressure chamber 42. The dust collection case 24 has the dust suction port 2 a that projects forward of the negative pressure chamber 42 and communicates with the negative pressure chamber 42. Further, the negative pressure chamber 42 of the dust collection case 24 is provided with a dust separator 44 that separates using the inertia force of the dust in the sucked air.

  The dust separator 44 includes a separation cylinder part 45 having a hollow frustum shape in which a large-diameter frame part 45a and a small-diameter frame part 45b are integrally connected by a plurality of ribs provided at intervals in the circumferential direction, and the cylinder part 45. A filter-type first filter 46 having a truncated cone shape such as a net of a predetermined mesh, and a communication cylinder part 47 provided by communicating the small-diameter frame part 45b of the separation cylinder part 45 and the dust storage part 41; It has. The dust separator 44 has the downstream opening 2a1 of the dust suction port 2a located inside the large diameter frame portion 45a to connect the large diameter frame portion 45a to the container portion 24a and the downstream opening of the communication cylinder portion 47. An end (exit) is provided to be connected to the upper part of the partition wall 43. By providing the dust separator 44 in this way, the inside of the separation cylinder portion 45 communicates straight with the dust suction port 2a on the upstream side, and the negative pressure chamber 42 via the first filter 46 on the downstream side. Communicating with

  Although not shown in the drawing, the communication cylinder portion 47 is located on the downstream side of the small-diameter frame portion 45b and faces the small-diameter frame portion 45b. And a second guide wall portion. The second guide wall portion is provided so as to be able to guide air obliquely downward toward the upper inner wall surface of the dust storage portion 41, and thereby a swirl flow along the inner peripheral surface of the dust storage portion 41 is introduced into the dust storage portion 41. It can be formed. A filter-type second filter 48 such as a net communicating with the dust storage chamber 41 and the negative pressure chamber 42 is attached to the through hole opened in the ceiling wall portion of the partition wall 43.

  The dust collection case 24 has a handle 49 for carrying the dust collection case 24 independently from the main body case 23, and has a bottom lid 50 for opening and closing the lower end opening of the dust storage chamber 41. The bottom lid 50 is provided so as to be opened by pressing a lid operation button (not shown) provided on the handle 49. Furthermore, a wall portion 52 that forms a fine dust reservoir 51 is integrally provided at the lower end of the rear opening of the container portion 24a of the dust collecting case 24. The upper and lower ends of the fine dust reservoir 51 are opened, and the lower end opening thereof is opened and closed by the bottom lid 50 together with the lower end opening of the dust chamber 41.

  The third filter 30 is detachably attached to the rear opening of the container portion 24a of the dust collecting case 24. The third filter 30 can be used as long as it is a filtration type, but in this embodiment, the filter frame 55 made of synthetic resin and the filter mat are pleated so as to have a waveform, and the inside of the filter frame 55 And a filter element 56 attached thereto. The lower end of the filter 30 is placed on the wall 52 so that a number of grooves on the upstream side (front side) and a number of grooves on the downstream side (back side) of the filter element 56 extend in the vertical direction. The rear opening of the container part 24a is closed in a standing posture.

  As the dust collecting case 24 is attached to the main body case 23 together with the third filter 30, the tip of the dust removal convex portion 32 c enters the groove on the back surface side of the filter element 56 as shown in FIG. 2. . Thereby, when the dust remover 32 is driven to rotate about the shaft portion 31b, the dust removal convex portion 32c gets over the bent portion protruding in the back surface direction between the grooves on the back surface side of the filter element 56, so that the filter element 56 can be vibrated. The lower frame portion 55 a of the filter frame 55 placed on the wall portion 52 does not have a width that covers the entire upper end opening of the fine dust reservoir 51, and a part of the upper end opening of the fine dust reservoir 51 is not covered. It is open. Therefore, as described above, when the filter element 56 is vibrated, the dust that freely falls from the upstream surface of this element can be accommodated in the fine dust reservoir 51 communicating downward. .

  The cordless vacuum cleaner having the above-described configuration drives the electric blower 25 with the electric power of the secondary battery 26 to suck dust on the surface to be cleaned together with air through the air flow introducing means 16, thereby obtaining a vacuum suction type. A cleaning operation can be performed. In this case, in this embodiment, the dust is next separated from the dust-absorbing air (suction air) by the inertial separation action by the straight flow.

  This separation will be described. The sucked dust and air are sucked into the separation cylinder portion 45 of the dust separator 44, and a part of the dust and air is sucked into the negative pressure chamber 42 of the dust collecting case 24 through the first filter 46. The air passes through the third filter 30 and is sucked into the suction port 25a of the electric blower 25.

  In such suction, dust having a mass greater than or equal to a predetermined amount sucked into the separation cylinder portion 45 linearly extending in the front-rear direction of the cleaner body 2 is suddenly changed in direction due to its inertia, and the first filter 46. Cannot pass through. For this reason, the dust having the mass is separated from the air passing through the first filter 46 and travels straight in the downstream direction, collides with the first guide wall portion of the communication tube portion 47, and moves along the second guide wall portion. It is introduced into the reservoir chamber 41.

  At the same time, a part of the air is introduced into the dust chamber 41 through the communication tube portion 47 in the same manner as the dust having the mass, and the downward swirling flow rotates along the inner peripheral surface of the dust chamber 41. It becomes. For this reason, the dust introduced into the dust chamber 41 is accumulated while being compressed along the lower inner peripheral surface of the dust chamber 41 by the swirling flow. The air that has been introduced into the dust chamber 41 and turned into a swirling flow is lifted and reversed at the center of the dust chamber 41 and is sucked into the negative pressure chamber 42 through the second filter 48.

  On the other hand, the lighter weight dust does not go straight through the separation cylinder portion 45 but flows into the negative pressure chamber 42 on the air passing through the first filter 46 by the negative intake pressure of the electric blower 25. 46 is attached to the inner peripheral surface.

  As described above, in the dust separator 44, dust having a large mass such as coarse dust tries to go straight without rotating the dust-containing air and centrifuging the dust and air while reversing the traveling direction of the swirl flow. Since this dust is separated from the air by utilizing the inertial force, the air path loss in the dust separator 44 is small.

  The fine dust flowing on the air sucked into the negative pressure chamber 42 due to the inertia separation is filtered by the third filter 30 before being sucked into the electric blower 25, and the upstream surface of the filter element 56. To be captured. In the above cleaning, the air that has passed through the third filter 30 is sucked into the electric blower 25 through the dust remover 32 and the vent hole 31a of the support frame 31, but in this case, the dust removal device 27 is not operated. The dust removing device 27 does not become a large air path resistance.

  When cleaning is completed or when cleaning is interrupted due to power consumption of the secondary battery 26, the user generally puts the cleaner body 2 in an upright position and places it on the charging stand 1. It is. Thereby, the power receiving terminal 29 of the cleaner main body 2 in the state where the operation is stopped and the output terminal 11a of the charging stand 1 are connected. Since commercial power is always supplied to the charging device 11 in the charging stand 1, charging with respect to the secondary battery 26 in the cleaner body 2 is started simultaneously with the placement, for example, along with the placement.

  The start of charging is detected by the control device 28 by a current supplied from the control device 28 via the signal line 37. Based on this, the control device 28 controls the drive circuit 36 through the dust removal control unit 28a to cut off the energization to the electric blower 25, and to the dust removal motor 33 of the dust removal device 27 as follows. Energize continuously for hours.

  That is, based on the fact that the user places the vacuum cleaner main body 2 on the charging stand 1 in order to start charging as described above, before starting charging, the power of the secondary battery 26 and the like is used for dusting. The dust removal device (dust removal mechanism) 27 can be quickly operated by supplying the electric motor 33. When the dust removing device 27 is driven, the dust remover 32 is rotated by the power of the electric motor 33 as described above, so that the filter element 56 of the third filter 30 is vibrated by the dust removing convex portion 32c, and the element 56 The trapped dust is dropped. Therefore, automatic dust removal of the third filter 30 can be performed at an early stage without leaving a long time since the dust is captured by the third filter 30 during cleaning.

  As described above, the automatic dust removal of the third filter 30 that suppresses the suction of dust into the electric blower 25 is performed by the user following the cleaning end or the cleaning interruption due to the power consumption of the secondary battery 26 by the user. This is carried out based on the fact that the secondary battery 26 can be charged by being set on the charging stand 1. As a result, early dust removal is quickly and automatically performed without taking a long time since the dust is captured by the third filter 30 during cleaning.

  That is, early dust removal can be performed by automatically vibrating the filter element 56 in a state where the dust trapped by the third filter 30 does not absorb moisture and start to solidify. For this reason, the effect of dust removal is high. Furthermore, since the clogging of the third filter 30 due to dust dropping performed at such timing is performed every time the cleaner body 2 is placed on the charging stand 1, a normal operation such as closing the cleaner body 2 is performed. The operation can be repeated almost regularly without requiring any special work for dust removal, which is convenient for use.

  In particular, in the present embodiment, although the dust separator 44 is inertially separated, the amount of fine dust adhering to the third filter 30 tends to be large. The clogging of the third filter 30 can be eliminated almost immediately after use. For this reason, it can be suppressed that the dust trapped in the third filter 30 before the next cleaning is solidified and the airflow resistance reduces the inertial separation effect.

  In addition, since the clogging of the third filter 30 described above is performed in a state in which the operation of the cleaner body 2 is stopped, it is also preferable in that the electric blower 25 does not suck in fine dust due to dust removal. . Incidentally, if it is assumed that the dust removing device 27 is operated in the state where the electric blower 25 is operated, the attached fine dust is caused by distortion or the like in the filter tissue of the vibrating filter element 56. It becomes easy to pass through the filter element 56. At the same time, the dust falling due to the vibration of the filter element 56 rises again and is easily attracted to the surface of the filter element 56, so that effective dust removal becomes difficult.

  The dust removal operation is automatically terminated after a predetermined time from the start by the dust removal control unit 28a. As a result, the filter element 56 can be vibrated for an unnecessarily long time so that the life of the element 56 is not shortened.

  At the same time, when the electric blower 25 is operated via the operation unit 20 during the dust removal operation due to a user's erroneous operation or the like, the dust removal control unit 28a supplies the dust removal motor 33 via the drive circuit 36. The energization is turned off and the operation of the dust removing device 27 is stopped. Thereby, it can suppress that the electric blower 25 sucks in fine dust.

  When the secondary battery 26 reaches full charge, the control device 28 detects this and stops charging the secondary battery 26.

  FIG. 6 shows a second embodiment of the present invention. Since this embodiment has basically the same configuration as that of the first embodiment, the same configuration is denoted by the same reference numeral as that of the first embodiment, description of the configuration and operation is omitted, and different configurations are described below. To do. For the same configuration, refer to FIGS.

  In 2nd Embodiment, the charging device 11 which charges the secondary battery 26 in the cleaner body 2 is incorporated, and the power receiving terminal 29 is electrically connected to the both poles. The charging stand 1 has a built-in power supply circuit 10 to which a power plug 12 is connected. A pair of output terminals 10 a electrically connected to the circuit 10 are disposed in the terminal receiving portion 15. The output terminal 10 a is connected to the power receiving terminal 29 of the main body 2 when the cleaner main body 2 is placed on the charging stand 1. Configurations other than those described above are the same as those in the first embodiment, including configurations not shown in FIG.

  Therefore, also in the second embodiment, the automatic dust removal of the third filter 30 that suppresses the suction of dust into the electric blower 25 is performed when cleaning is completed and the secondary battery 26 can be charged, or In accordance with the cleaning interruption due to the power consumption of the secondary battery 26, the user quickly and automatically removes the dust based on the fact that the user places and sets the cordless type cleaner body 2 on the charging stand 1. As described above, the third filter 30 can be automatically dusted early without taking a long time from the dust trapping by the third filter 30 accompanying the cleaning, so that the problem of the present invention can be solved.

  In addition, 2nd Embodiment may incorporate the power supply circuit 10 in the cleaner body 2 'as shown with a dashed-two dotted line in FIG. 6, and may be implemented as a vacuum cleaner with a cord. In this case, the charging stand 1 may be omitted, and the power supply circuit 10 and the charging device 11 can be directly and electrically connected by electric wires, and a cord reel in which a power cord is taken in and out of the cleaner body 2. (Not shown).

  For this reason, the rechargeable battery 26 is charged by inserting and connecting the power plug 12 connected to the power cord to a commercial power source. In this embodiment, the dust removal control unit 28a of the control device (control means) 28 is configured to automatically operate the dust removal device (dust removal means) 27 based on the power plug 12 being connected to a commercial power source. The

  As a result, when the cleaning is completed and the secondary battery 26 can be charged, or in accordance with the cleaning interruption due to the power consumption of the secondary battery 26, the user plugs the power plug 12 into a commercial power source in order to start charging. Based on the plug-in connection, the dust is automatically and promptly removed. Thereby, since the automatic dust drop of the 3rd filter 30 can be carried out at an early stage, without putting a long time from the capture | acquisition of the dust with the 3rd filter 30 accompanying cleaning, the subject of this invention can be solved.

  Each of the above embodiments is configured as described above, but the present invention is not limited thereto.

  For example, in the first and second embodiments, the dust removal controller 28a of the control device (control means) 28 is replaced with the vacuum cleaner body 2 installed on the charging stand 1 in place of the functions described in these embodiments. It is good also as a structure which has the function to drive the electric motor 33 for dust removal automatically for the predetermined time during the charge with respect to the secondary battery 26 inside. Thereby, when cleaning is completed and charging to the secondary battery 26 is possible, or in accordance with the cleaning interruption due to power consumption of the secondary battery 26, the main body of the vacuum cleaner is placed in the charging stand 1 so that the user can start charging. For example, when the charging is started, for example, simultaneously with the start of charging, power such as the secondary battery 26 is supplied to the dusting motor 33 to quickly operate the dust removing device (dust removing mechanism) 27. it can. Therefore, automatic dust removal of the third filter 30 can be performed at an early stage without taking a long time since the dust is captured by the third filter 30 during cleaning, so that the problem of the present invention can be solved.

  Furthermore, in the first and second embodiments, the dust removal control unit 28a of the control device (control means) 28 is replaced with the vacuum cleaner body 2 installed on the charging stand 1 in place of the functions described in these embodiments. It is good also as a structure which has a function which interrupts charge and operates the dust removal apparatus (dust removal mechanism) 27 after the predetermined time from the charge start with respect to the secondary battery 26 inside. Thereby, when cleaning is completed and charging to the secondary battery 26 is possible, or in accordance with the cleaning interruption due to power consumption of the secondary battery 26, the main body of the vacuum cleaner is placed in the charging stand 1 so that the user can start charging. After charging 2 for a predetermined time, the power of the secondary battery 26 can be supplied to the dusting motor 33 and the dust removing device (dust removing mechanism) 27 can be operated quickly. Therefore, since the automatic dust removal of the third filter 30 can be performed at an early stage without leaving a long time since the dust is captured by the third filter 30 accompanying the cleaning, the problem of the present invention can be solved.
