Description

The present invention relates to an electric vacuum for sucking and collecting fallen leaves and the like.

For example, in an electric vacuum as in Patent Document 1 below, an air flow is generated by the rotation of a fan to suck in dust such as fallen leaves. The inhaled fallen leaves are crushed by a fan and sent to a dust collection bag. The dust bag is breathable, and the crushed fallen leaves are filtered and collected by the dust bag. However, since the dust collecting bag is breathable, fine dust passes through the eyes of the dust collecting bag and diffuses to the surroundings. On the other hand, if the dust collecting bag is made finer, clogging is likely to occur and the suction performance is likely to be deteriorated. On the contrary, if the dust collecting bag is roughened, clogging is less likely to occur, but fine dust is likely to be scattered.

Japanese Patent No. 3501750

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an electric vacuum capable of suppressing deterioration of suction performance while suppressing scattering of fine dust.

The present invention has been made to solve the above problems, and the electric vacuum according to the present invention generates an air flow in the middle of the air flow path and crushes the sucked dust such as fallen leaves to the exhaust side. It is an electric vacuum equipped with a sending fan, and is characterized by having a cyclone device on the exhaust side of the fan.

Since the electric vacuum having this configuration is provided with a cyclone device, a non-breathable non-breathable plastic film dust bag can be used, and dust can be collected in the dust bag. can. Therefore, fine dust is less likely to be scattered around during the work, and the work can be performed in a good working environment. In addition, it is not necessary to transfer the accumulated dust to another garbage bag, and the accumulated dust can be disposed of together with the garbage bag. Further, since the cyclone device is provided, the suction performance is unlikely to deteriorate, and the suction work can be performed with a stable suction force. On the other hand, the sucked dust such as fallen leaves is crushed by the fan and sent to the exhaust side. The dust on the exhaust side of the fan is smaller than the dust on the intake side of the fan, and the cyclone device can be miniaturized by providing a cyclone device in the air flow path on the exhaust side of the fan.

In particular, it is preferable that the vacuum body is provided with a grip portion, a cyclone device is provided below the grip portion, and the exhaust port of the cyclone device faces the rear side. The fact that the exhaust port of the cyclone device faces the rear side is not limited to the case where the exhaust port of the cyclone device faces directly behind, and the exhaust port of the cyclone device may face diagonally upward. Therefore, the central axis of the cyclone device is not limited to horizontal, and may be inclined in the vertical direction so that the front side is the lower side and the rear side is the upper side. Further, the central axis of the cyclone device may be inclined at an angle of 45 degrees or less in the left-right direction. In any case, it is preferable that the exhaust port of the cyclone device faces the rear side rather than facing the front side, directly above or directly beside it. According to this configuration, since the cyclone device is located below the grip portion, the cyclone device is less likely to get in the way when the operator grips the grip portion and performs the work. In addition, the cyclone device does not obstruct the view of the operator when sucking the fallen leaves or the like, which is the object to be sucked, from the intake port located on the front side. Furthermore, since the cyclone device is arranged with the exhaust port facing the rear side, the width of the electric vacuum is larger than that of the configuration in which the cyclone device is arranged with the exhaust port facing the right side or the left side, for example. It is hard to become. When gripping the gripped portion with the right hand, the operator often stands on the left side of the electric vacuum, and when gripping the gripped portion with the left hand, the worker stands on the right side of the electric vacuum. Therefore, if the width of the electric vacuum becomes large, it becomes difficult to perform the work. However, with the above configuration, the width of the electric vacuum does not easily become large, so that the operability is good. Moreover, since the exhaust port faces the rear side instead of the right side or the left side, it is difficult for the worker standing on the left side or the right side of the electric vacuum to be exposed to the exhaust air discharged from the cyclone device.

Further, the cyclone device is configured to be detachably attached to the attachment portion of the vacuum body, and the cyclone device and the breathable dust collecting bag are interchangeably attached to the attachment portion of the vacuum body. preferable. If the cyclone device is detachably configured and can be replaced with a breathable dust collecting bag in this way, the cyclone device and the breathable dust collecting bag can be used properly according to the situation. For example, when collecting a large amount of fallen leaves, it is possible to work efficiently by using a large-capacity breathable dust bag, and the breathable dust bag is lighter than a cyclone device. There is also the advantage of having.

As described above, since the cyclone device is provided, dust can be collected in a non-breathable garbage bag, and the scattering of fine dust is suppressed. Further, by providing a cyclone device, deterioration of suction performance can be prevented. Further, by providing a cyclone device on the exhaust side of the fan, a small cyclone device can be used, and the electric vacuum can be made smaller and lighter.

The dust collecting unit includes a cyclone unit 2 and a bag unit 3, both of which are configured to be detachably attached to the same attachment portion 20 of the vacuum body 1. FIG. 1 shows a state in which the cyclone unit 2 is attached to the vacuum body 1, and FIG. 2 shows a state in which the cyclone unit 2 is removed. On the other hand, FIG. 3 shows a state in which the bag unit 3 is attached to the vacuum body 1. As described above, the vacuum main body 1 is shared, and one of the cyclone unit 2 and the bag unit 3 can be attached to one attachment portion 20 of the vacuum main body 1 for use.

As shown in FIGS. 1 to 3, the vacuum main body 1 includes a nozzle portion 21 extending diagonally downward from the rear side toward the front side, and wheels 7 are provided in the lower portion of the front portion of the nozzle portion 21. ..

A blower section 16 extends in parallel with the air flow path 13 on the intake side below the air flow path 13 on the intake side, and an exhaust port 12 for the blower opens at the lower part of the front end portion of the nozzle portion 21. There is. Therefore, the intake port 10 and the exhaust port 12 for the blower are arranged one above the other.

The upper part of the vacuum body 1 is provided with a main handle portion 22 located on the rear side and a sub handle portion 23 located on the front side thereof. In the present embodiment, the main handle portion 22 and the sub handle portion 23 form a grip portion. The sub handle portion 23 is located above the rear end portion of the nozzle portion 21, and the main handle portion 22 is located at the rearmost portion of the vacuum body 1. A switch 27 for operating and stopping the motor 4 is provided on the upper surface between the sub-handle portion 23 and the main handle portion 22.

The motor 4 is located on the front side of the main handle portion 22, is located on the rear side of the sub handle portion 23, and is located obliquely lower and rear side of the sub handle portion 23.

The nozzle portion 21 is inclined diagonally downward with respect to the rotation center axis of the motor 4 and the fan 5, and the fan 5 is located on the rear side of the rear end portion of the nozzle portion 21. The rotation direction of the fan 5 is counterclockwise when viewed from the front side as shown in FIG. 4, and when the fan 5 rotates, air is sucked from the intake port 10 and heads toward the fan 5. The fan 5 is configured to discharge the air coming from the front side to the outside in the radial direction, and is configured to be able to crush fallen leaves and the like.

As shown in FIG. 4, an air flow path is formed around the fan 5 so as to go around the fan 5 for substantially one round. The air flow path that goes around the fan 5 is a section on the upstream side of the air flow path on the exhaust side and is a common section 14. The common section 14 is formed so as to gradually increase in diameter along the rotation direction of the fan 5. Specifically, the common section 14 gradually increases in diameter counterclockwise from the lower right position when viewed from the front side, and becomes the largest diameter at the lower left position. Therefore, the cross-sectional area of the common section 14 gradually increases along the rotation direction of the fan 5 and becomes the largest at the lower position of the fan 5.

<Cyclone unit 2>
The electric vacuum includes a cyclone unit 2 for filtering and collecting dust such as fallen leaves crushed by the fan 5. The cyclone unit 2 includes a mounting holder 50, a unit main body, and a dust case 70. The mounting holder 50 is a member for mounting the cyclone unit 2 to the mounting portion 20 of the vacuum body 1. The mounting holder 50 includes a front locking portion 51 located at the front end portion and a rear locking portion 52 located at the rear end portion, and the vacuum main body 1 is provided with two front and rear locking portions 51 and 52. It is configured so that it can be detachably attached to the bottom. The front locking portion 51 is locked to the front main body locking portion 24 provided at the lower part of the vacuum main body 1 and serves as a rotation fulcrum at the time of attachment / detachment. The locking portion 52 on the rear side is locked to the main body locking portion 25 on the rear side, and the locked state can be released by pressing. When attaching / detaching the cyclone unit 2 to / from the vacuum main body 1, the front locking portion 51 is locked to the front main body locking portion 24, and the cyclone unit 2 is used as a fulcrum in the left-right direction with the front locking portion 51 as a fulcrum. Rotate up and down around the axis.

The unit main body is a main part of the cyclone unit 2 provided with the cyclone device S, and is attached to the lower side of the attachment holder 50 with screws or the like. The main body of the unit is for filtering dust such as crushed fallen leaves. The unit main body includes a cyclone housing 60 having an outer cylinder portion 61, and an inner cylinder body 62 removably attached to the cyclone housing 60. In the present embodiment, the cyclone device S is composed of the outer cylinder portion 61 and the inner cylinder body 62 of the cyclone housing 60. The cyclone housing 60 is attached to the attachment holder 50.

The cyclone housing 60 includes an outer cylinder portion 61 having a connection opening 63 connected to an exhaust port 11 for dust collection of the vacuum body 1, and a lid portion 64 for covering the upper surface opening of the dust case 70. I have. The outer cylinder portion 61 is arranged in a forward tilted posture in which the direction of the center line (axis direction) is the front-rear direction and the front end is located on the lower side with respect to the rear end. Therefore, the outer cylinder portion 61 extends substantially parallel to the nozzle portion 21. The outer cylinder portion 61 is located below the motor 4 as a whole and below the main handle portion 22 and the sub handle portion 23. Specifically, the rear end portion of the outer cylinder portion 61 is the main handle. It is located below the portion 22, and the front end of the outer cylinder portion 61 is located below the sub-handle portion 23. Both ends of the outer cylinder 61 are open. The connection opening 63 of the outer cylinder portion 61 is formed at the rear portion and the upper portion of the outer cylinder portion 61. The connection opening 63 is open on the upper side and diagonally forward in order to face the dust collecting exhaust port 11.

The inner cylinder body 62 is inserted from the rear end portion of the outer cylinder portion 61 into the inside of the outer cylinder portion 61. The inner cylinder 62 is coaxially located inside the outer cylinder 61 of the cyclone housing 60 with a gap, and a tubular space is formed between the inner cylinder 62 and the outer cylinder 61. ing. Therefore, the inner cylinder 62 also extends substantially parallel to the nozzle portion 21. The inner cylinder 62 is a cylinder having one end closed and the other end open, and is mounted inside the outer cylinder portion 61 so that the closed side is the front side and the opening side is the rear side. An annular collar portion 65 is formed at the rear end portion of the inner cylinder 62, and the collar 65 is the rear end of the tubular space formed between the inner cylinder 62 and the outer cylinder 61. Close the part. The peripheral wall portion 66 of the inner cylinder 62 has a tapered shape that gradually decreases in diameter toward the front end portion on the closed side. Therefore, the tubular space formed between the outer cylinder portion 61 and the inner cylinder body 62 gradually expands from the rear side to the front side. While a large number of small holes 67 are formed in the peripheral wall portion 66 of the inner cylinder body 62, the small holes 67 are not formed in the front wall portion 68 which is the bottom surface portion of the inner cylinder body 62. Small holes 67 are formed in most of the peripheral wall portion 66 of the inner cylinder 62, but the dust sent through the exhaust port 11 for dust collection and the connection opening 63 of the outer cylinder 61 is small. In order to prevent the holes 67 from entering, as shown in FIG. 4, there is a region in the rear part of the peripheral wall portion 66 and in the upper portion where the small hole 67 is not formed in the entire circumference of the peripheral wall portion 66. .. The region where the small holes 67 are not formed is a portion of the entire circumference facing the connection opening 63. The front end portion (front wall portion 68) of the inner cylinder body 62 is substantially the same as the front end portion of the outer cylinder portion 61 in the front-rear direction.

The center line of the inner cylinder 62 and the center line of the outer cylinder 61 are the center lines of the cyclone device S. Therefore, the cyclone device S is substantially parallel to the nozzle portion 21. The position of the center line of the cyclone device S in the left-right direction is substantially the same as the position of the center line of the fan 5 in the left-right direction. More specifically, as shown in FIG. 4, the position of the center line of the cyclone device S in the left-right direction is slightly offset in the left-right direction with respect to the position of the center line of the fan 5 in the left-right direction. , The electric vacuum is on the left side when viewed from the front side. As described above, the fan 5 rotates counterclockwise when viewed from the front side, and the air flow flows counterclockwise when viewed from the front side in the common section 14 orbiting the fan 5. On the other hand, in the cyclone device S, an air flow flows clockwise when viewed from the front side in a tubular space between the outer cylinder portion 61 and the inner cylinder body 62. In this way, the rotation direction of the fan 5 and the flow direction of the air flow in the common section 14 orbiting the fan 5 are opposite to the flow direction of the air flow in the cyclone device S.

Then, the dust crushed together with the air flow is sent from the dust collecting exhaust port 11 to the tubular space between the outer cylinder portion 61 and the inner cylinder body 62. Dust orbits a tubular space with air. The air passes through the small hole 67 on the peripheral wall of the inner cylinder 62 inward and is discharged to the outside through the rear end opening of the inner cylinder 62. In this way, the rear end opening of the inner cylinder 62 becomes the exhaust port S1 of the cyclone device S. The dust goes around the tubular space in a spiral shape and faces the front side, is discharged downward from the front end opening of the outer cylinder portion 61, and falls into the dust case 70.

The dust case 70 is detachably attached to the lid portion 64 of the cyclone housing 60 from below. The dust case 70 has a bottomed box shape with a top opening and is not breathable, and is preferably made of synthetic resin. In this embodiment, it has a rectangular parallelepiped shape that is long in the front-rear direction. As described above, in the reference state where the center lines of the motor 4 and the fan 5 are horizontal, the dust case 70 is in a state of being tilted rearward by a predetermined angle. However, when the dust case 70 is in a horizontal state so that the bottom surface of the dust case 70 is substantially parallel to the ground, it is the basic suction work posture of the electric vacuum, and in that state, the center line of the motor 4 and the fan 5 Is in an inclined state with the front side on the lower side.

A pair of front and rear locking portions 71 are provided on the upper end portion of the dust case 70, and a pair of front and rear locking portions 69 are provided on the lid portion 64 of the cyclone housing 60 correspondingly. The dust case 70 can be attached to the lid portion 64 by locking the pair of front and rear locking portions 71 of the dust case 70 to the pair of front and rear locking portions 69 of the lid portion 64, respectively. By attaching the dust case 70 to the lid portion 64, the upper surface opening of the dust case 70 is closed by the lid portion 64. In FIG. 1, a state in which the dust case 70 is removed from the lid portion 64 is shown by a chain double-dashed line.

The dust case 70 has shape retention and maintains its box shape by its own rigidity even when it is empty. It is preferable that at least a part of the dust case 70 is transparent so that the inside can be seen from the outside. In the present embodiment, a transparent window portion 72 is provided on the side wall portion of the dust case 70, and the internal state can be visually recognized from the outside through the window portion 72. A non-breathable garbage bag 73 is attached to the inside of the dust case 70, and dust can be collected in the garbage bag 73. The garbage bag 73 may be a general-purpose one or a dedicated one. The garbage bag 73 can be replaced by removing the dust case 70 from the lid portion 64.

<Bag unit 3>
FIG. 3 shows a state in which the bag unit 3 is attached to the vacuum body 1. The bag unit 3 includes a dust collecting bag 80 mainly made of a flexible and breathable cloth, and a mounting holder 50 for detachably attaching the dust collecting bag 80 to the mounting portion 20 of the vacuum body 1. ing. The mounting holder 50 of the bag unit 3 has the same specifications as the mounting holder 50 of the cyclone unit 2, and the common mounting holder 50 is used for the bag unit 3 and the cyclone unit 2. A disposal port (not shown) that can be opened and closed by a fastener is provided on the rear surface side of the dust collection bag 80, and dust collected inside can be taken out from the disposal port and replaced with another garbage bag for disposal. The dust collecting bag 80 includes a ring 8 that can be hooked on a hook 26 provided on the lower surface of the nozzle portion 21 of the vacuum body 1.

In the electric vacuum configured as described above, since the cyclone unit 2 is attached as a dust collecting unit, a non-breathable dust bag 73 can be used, and dust is collected in the dust bag 73. be able to. Therefore, fine dust is less likely to be scattered around during the work, and the work can be performed in a good working environment. Further, it is not necessary to transfer the accumulated dust to another bag, and the accumulated dust can be taken out from the dust case 70 together with the garbage bag 73 and disposed of.

Further, since the cyclone device S is provided, the suction performance is unlikely to deteriorate, and the suction work can be performed with a stable suction force. The dust on the exhaust side of the fan 5 is smaller than the dust on the intake side of the fan 5, and the cyclone device S is provided on the exhaust side of the fan 5, so that a small cyclone device S is sufficient. The electric vacuum can be miniaturized.

Further, since the cyclone device S is arranged under the main handle portion 22, the cyclone device S does not easily interfere with the work, and when the cyclone device S sucks the fallen leaves or the like from the intake port 10, the cyclone device S is an operator. It is easy to perform suction work without obstructing the view of the cyclone. Further, since the exhaust port S1 of the cyclone device S faces the rear side, the width of the cyclone unit 2 does not increase as compared with the case where the exhaust port S1 of the cyclone device S faces the right side or the left side. , The width of the electric vacuum can be suppressed, making it easy to work. Moreover, since the exhaust port S1 of the cyclone device S faces the rear side instead of the right side or the left side, it is difficult for the exhaust air of the cyclone device S to hit the worker standing on the left side or the right side of the electric vacuum. Since the dust case 70 also has a rectangular parallelepiped shape that is long in the front-rear direction, the width can be suppressed. Further, since the cyclone device S is not in a horizontal posture but in a forward leaning posture in which the front side is lowered like the nozzle portion 20, dust smoothly falls from the front end opening of the outer cylinder portion 61 into the dust case 70.

Further, since the rotation direction of the fan 5 and the rotation direction (circulation direction) of the air flow in the cyclone device S are opposite to each other, the air flow circulating around the fan 5 smoothly flows into the cyclone device S. Can be done. Further, it becomes easy to bring the center line of the cyclone device S closer to the center line of the fan 5 in the left-right direction, and it is possible to prevent the cyclone unit 2 from protruding laterally from the vacuum body 1 and the width of the electric vacuum. Can be suppressed.

Further, both the cyclone unit 2 and the bag unit 3 are detachable from the attachment portion 20 of the vacuum body 1, and the cyclone unit 2 and the bag unit 3 can be arbitrarily replaced. Therefore, the cyclone unit 2 and the bag unit 3 can be used properly according to the situation. For example, in a situation where you want to enjoy the advantages of the cyclone unit 2 as described above, you can work by attaching the cyclone unit 2 to the vacuum body 1, and conversely, you can collect a large amount of fallen leaves or have the advantage of being lightweight. When it is desired to utilize the work, the bag unit 3 can be attached to perform the work.

In the present embodiment, the cyclone unit 2 is removable and can be replaced with the bag unit 3 after being removed. However, the cyclone unit 2 is not removable and the cyclone device S. May be inseparably integrated with the vacuum body 1.

Further, although the device having the blower function has been described in the above embodiment, the device may not have the blower function and therefore may not have the exhaust port 12 for the blower or the switching drum 6.

Further, the arrangement mode of the cyclone device S can be variously changed, and is not limited to the configuration in which the cyclone device S is arranged below the main handle portion 22 and the sub handle portion 23 as the grip portion as described above. The cyclone device S may be located on the front side of the handle portion 90 which is the grip portion as described above. The electric vacuum shown in FIG. 6 is a vertical type, in which the intake port 10 opens downward on the front side of the wheel 7, and the fan 5 and the motor 4 are arranged at a position away from the wheel 7 on the upper side. Has been done. Specifically, the fan 5 and the motor 4 are located directly above the wheels 7 and separated from each other. The center line of the fan 5 and the center line of the motor 4 face in the vertical direction, the motor 4 and the fan 5 are on the same line, and the motor 4 is located above the fan 5. The nozzle portion 21 extends rearward from the intake port 10 toward the wheel 7 and then rises to reach the fan 5. The air flow path 13 on the intake side formed inside the nozzle portion 21 is also formed along the shape of the nozzle portion 21, and extends from the intake port 10 to the rear side and then rises to reach the fan 5. .. The handle portion 90 is located above and behind the motor 4. The handle portion 90 extends toward the rear side while being inclined substantially horizontally or slightly downward, and a switch 27 for operating and stopping the motor 4 is provided on the lower surface thereof.

The air flow path 91 on the exhaust side is formed on the front side from the fan 5, and a cyclone device S is provided on the exhaust side of the fan 5. The air flow path 91 on the exhaust side is connected to the cyclone device S from the fan 5 toward the front side and then toward the upper side. The cyclone device S is arranged so as to have a center line in the vertical direction. Therefore, both the cyclone device S and the fan 5 are arranged along the vertical direction and are in a parallel relationship. Similar to the above, the cyclone device S includes an outer cylinder portion 61 and an inner cylinder body 62 (inner cylinder portion). The center line of the outer cylinder portion 61 and the center line of the inner cylinder body 62 are coaxial and run in the vertical direction. As shown in FIG. 7, the fan 5 rotates counterclockwise when viewed from below, so that the air flow flows counterclockwise when viewed from below around the fan 5. On the other hand, in the cyclone device S, the air flow flows clockwise when viewed from below. As described above, the rotation direction of the air flow in the cyclone device S, the rotation direction of the fan 5, and the rotation direction of the air flow flowing around the fan 5 are opposite to each other. The center line of the fan 5 and the center line of the cyclone device S have the same position in the left-right direction and are arranged without offset. A dust case 70 is detachably attached directly below the cyclone device S. Since the air flow path 91 on the exhaust side rises between the fan 5 and the cyclone device S and the height of the cyclone device S is set to substantially the same height as the heights of the fan 5 and the motor 4, the cyclone device S The separation distance between the cyclone device S and the nozzle unit 21 can be increased, and a large dust case 70 can be arranged between the cyclone device S and the nozzle unit 21. The dust case 70 is arranged so as not to protrude from the lower portion of the nozzle portion 21 to the front side.
