As described above, in the technique shown in Patent Document 1, for example, by connecting the blower nozzle to the exhaust port, the exhaust gas from the exhaust port can be used as a blower. The exhaust port to which the blower nozzle is attached / detached when the blower nozzle is not used is covered with an exhaust cover to suppress the exhaust air velocity from the exhaust port. However, in such a technique, since the exhaust port is covered with the exhaust cover when the blower nozzle is not used, the pressure loss at the exhaust port becomes large. For this reason, there is a risk that the suction force will be reduced during normal suction cleaning by a vacuum cleaner.

The present invention has been made to solve such a problem. The purpose is to prevent dust from being rolled up on the surface to be cleaned by exhaust when the blower nozzle is not in use, without reducing the suction force during normal suction cleaning by a vacuum cleaner, and when the blower nozzle is used, the blower nozzle is used. The purpose is to obtain an electric vacuum cleaner that can improve the performance as a blower by increasing the exhaust air velocity from the exhaust port to which the is connected.

The electric vacuum cleaner according to the present invention has a main body having a suction port and having a dust collecting portion for collecting dust in the air sucked from the suction port, and a main body built in the main body and collecting the dust from the suction port. An electric blower that generates an air flow to be sucked into the dust portion is provided, and an exhaust air passage for exhausting the air that has passed through the dust collecting portion to the outside of the main body is formed inside the main body. The main body is formed with a first exhaust port communicating with the exhaust air passage and a second exhaust port communicating with the exhaust air passage and arranged at a position different from the first exhaust port. A blower nozzle can be attached to and detached from the second exhaust port, and when the blower nozzle is not attached to the second exhaust port, the amount of exhaust gas from the second exhaust port is used as the second exhaust gas. A shutter portion is provided in the mouth to reduce the amount of the blower nozzle as compared with the case where the blower nozzle is attached, and the shutter portion passes through the shutter portion in a state where the second exhaust port is closed to pass through the second exhaust port. air Ru der possible distribution.

According to the electric vacuum cleaner according to the present invention, it is possible to suppress dust winding on the surface to be cleaned by exhaust when the blower nozzle is not in use, without reducing the suction force during normal suction cleaning by the vacuum cleaner, and the blower. When the nozzle is used, the effect is that the performance as a blower can be improved by increasing the exhaust air velocity from the exhaust port to which the blower nozzle is connected.

In the following description, dust and other dust may be collectively referred to simply as "dust". In addition, air mixed with dust may be referred to as "dust-containing air". The air from which dust has been removed may be referred to as "clean air".

The vacuum cleaner 1 according to the first embodiment of the present invention is a cordless type vertical vacuum cleaner. As shown in FIG. 1, the vacuum cleaner 1 includes a main body 3, a pipe body 4, and a suction tool 5 as main components. As shown in FIGS. 2 to 4, the main body 3 includes a handle 15, an outer shell portion 16, and a dust collecting portion 17. The handle 15 is a portion that the user holds by hand while using the vacuum cleaner 1. The user can grasp the main body 3 of the vacuum cleaner 1 by grasping the handle 15.

The outer shell portion 16 is a member that forms the outer shell, that is, the outer cover of the main body 3. As shown in FIG. 3, an electric blower 23, a battery unit 19, and a control unit 24 are built in the outer shell portion 16 of the main body 3. The electric blower 23 is for generating the suction air of the vacuum cleaner 1. The battery unit 19 includes a secondary battery for driving the electric blower 23. The battery unit 19 in the first embodiment is an example of a power supply device that supplies electric power for driving the electric blower 23. The control unit 24 includes a circuit for controlling the operation of the electric blower 23 and the like.

The outer shell portion 16 includes a case portion 18 and a connecting pipe portion 20. The connecting pipe portion 20 is a hollow tubular member to which the pipe body 4 is detachably connected. The connection pipe portion 20 has a suction port 21 for sucking in dust. The suction port 21 is an opening formed at one end of the connecting pipe portion 20. Inside the connecting pipe portion 20, an air passage is formed to guide the airflow of dust-containing air that has passed through the suction port 21 to the dust collecting portion 17.

The handle 15 is arranged so as to be curved in a U shape so as to wrap around the side opposite to the side where the dust collecting portion 17 is arranged when viewed from the case portion 18. One end side of the handle 15 is arranged so as to be continuous in appearance with the other end side of the connecting pipe portion 20. The other end side of the handle 15 extends to the side opposite to the side on which the connecting pipe portion 20 is arranged when viewed from the case portion 18. The other end side of the handle 15 is connected to a strut portion protruding from the side surface of the case portion 18. An operation unit 22 is provided on the other end side of the handle 15. At least a part of the handle 15 exhibits a straight line along a preset axis. In the configuration of this embodiment, the operation portion 22 side of the handle 15 is linear.

The dust collecting unit 17 is for collecting dust in the dust-containing air sucked into the main body 3 by the suction air generated by the electric blower 23. As shown in FIG. 4, the dust collecting unit 17 is detachably attached to the main body 3. As shown in FIG. 5, the dust collecting portion 17 has a columnar appearance as a whole. The dust collecting unit 17 according to the first embodiment has a cyclone unit 26 and a filter unit 25. The cyclone unit 26 is a cyclone separation device. The cyclone unit 26 internally swirls the dust-containing air by the air flow generated by the electric blower 23 to separate dust from the dust-containing air. The filter unit 25 is for filtering fine dust that could not be completely separated by the cyclone unit 26 from the air flow.

In this way, the suction port 21 is formed in the main body 3. Further, the main body 3 has a dust collecting unit 17 that collects dust in the air sucked from the suction port 21. Then, the electric blower 23 built in the main body 3 generates an air flow sucked from the suction port 21 into the dust collecting unit 17.

An exhaust air passage is formed inside the main body 3. The exhaust air passage is an air passage for discharging the air that has passed through the dust collecting portion 17 to the outside of the main body 3. The main body 3 is formed with a first exhaust port 31 and a second exhaust port 32. Both the first exhaust port 31 and the second exhaust port 32 communicate with the exhaust air passage described above. In the configuration example of this embodiment, the first exhaust port 31 is formed at a position in the case portion 18 where the battery portion 19 is housed. Therefore, the battery unit 19 is arranged in the exhaust air passage at a position leading to the first exhaust port 31 in particular. In this configuration example, as shown in FIGS. 2 and 4, the first exhaust port 31 is provided on both sides of the case portion 18, respectively. That is, the first exhaust port 31 is arranged on the side surface of the main body 3.

The second exhaust port 32 is formed at a position different from that of the first exhaust port 31. In the configuration example of this embodiment, the second exhaust port 32 is formed on the other end side of the handle 15, that is, the end surface on the side where the operation portion 22 is provided, and more specifically, on the side surface of the support column portion of the handle 15. Has been done. That is, the second exhaust port 32 is arranged with respect to the handle 15 on the end side opposite to the end side where the first exhaust port 31 is arranged, away from the handle 15. The second exhaust port 32 is open in the same direction as the suction port 21. In the configuration example of this embodiment, the direction in which the second exhaust port 32 and the suction port 21 are opened is along the above-mentioned axis of the handle 15, and the dust collecting portion 17 is arranged when viewed from the case portion 18. It is the direction to be on the side.

The opening area of the second exhaust port 32 is larger than the opening area of the first exhaust port 31. In the configuration example of this embodiment, as described above, the first exhaust port 31 is provided on both sides of the case portion 18. The opening area of the second exhaust port 32 is larger than the total of these first exhaust ports 31.

The electric blower 23 is driven in response to an operation on the operation unit 22 provided on the handle 15. When the electric blower 23 is driven, a suction force acts inside the dust collecting portion 17 and the connecting pipe portion 20, and dust-containing air is sucked from the suction port 21. The dust-containing air sucked into the suction port 21 passes through the connecting pipe portion 20 and is taken into the inside of the dust collecting portion 17. In the dust collecting unit 17, dust is separated from the dust-containing air by the cyclone unit 26 and the filter unit 25. The clean air discharged from the dust collector 17 passes through the electric blower 23. The clean air that has passed through the electric blower 23 passes through the above-mentioned exhaust air passage and is discharged to the outside of the main body 3 from the first exhaust port 31 and the second exhaust port 32.

Here, as described above, the battery unit 19 is arranged in the exhaust air passage described above. Therefore, during the operation of the vacuum cleaner 1, the battery unit 19 can be cooled by the air flow in the exhaust air passage.

As shown in FIG. 1, the tubular body 4 is a hollow tubular member having a linear outer shape. One end side of the tubular body 4 is detachably connected to the suction port 21 of the main body 3. The other end side of the tubular body 4 is detachably connected to the suction tool 5.

The suction tool 5 includes a suction port body 14 and a connecting portion 13. The suction tool 5 is connected to the other end side of the tubular body 4 via the connecting portion 13. The suction tool 5 is for cleaning the surface to be cleaned. The surface to be cleaned is a surface extending parallel to a horizontal surface such as a floor surface. Most of the bottom surface of the suction port body 14 is arranged parallel to the surface to be cleaned. A suction tool opening (not shown) is formed on the bottom surface of the suction port body 14.

In a plan view, the shape of the suction port body 14 is rectangular. The cleaning direction of the suction port body 14 is referred to as the lateral direction of the suction port body 14. In a plan view, the direction perpendicular to the lateral direction of the suction port body 14 is referred to as the longitudinal direction of the suction port body 14. The length (maximum length) of the suction port body 14 in the longitudinal direction is longer than the length (maximum length) in the lateral direction.

One end of the connecting portion 13 is attached to the intermediate portion in the longitudinal direction of the suction port body 14 and to one side in the lateral direction via the joint structure. The other end side of the connecting portion 13 is detachably connected to the other end side of the pipe body 4 described above.

When the vacuum cleaner 1 configured as described above is used as a stick-type vacuum cleaner by connecting the main body 3, the pipe body 4 and the suction tool 5 so as to be integrated, the user can use the handle of the main body 3. Grasp 15 and clean the floor surface so that the longitudinal direction of the pipe body 4 is oblique as shown in FIG. 1, for example. Further, for example, when cleaning the ceiling surface or the like, as shown in FIG. 7, in a state where the main body 3 and the pipe body 4 are connected and the suction tool 5 is removed, the handle 15 of the main body 3 is grasped and the pipe body 4 is cleaned. The longitudinal direction of the is diagonally upward.

Further, the vacuum cleaner 1 according to the embodiment of the present invention can take a particularly two forms of "upright form" and "flat form" described below. In the upright form, the main body 3, the pipe body 4, and the suction tool 5 are connected so as to be integrated, and the bottom surface of the suction tool 5 is directed downward, and the bottom surface of the suction tool 5 and the pipe are formed by the joint structure of the connecting portion 13. It is a form in which the longitudinal axis of the body 4 is substantially perpendicular to the longitudinal axis. Examples of the upright form of the vacuum cleaner 1 are shown in FIGS. 8 to 10. The upright vacuum cleaner 1 can stand on its own.

In the flat form, the main body 3, the pipe body 4, and the suction tool 5 are connected so as to be integrated, and the bottom surface of the suction tool 5 is directed downward, and the bottom surface of the suction tool 5 and the pipe are formed by the joint structure of the connecting portion 13. It is a form in which the longitudinal axis of the body 4 is parallel to each other. The flat form of the vacuum cleaner 1 is shown in FIG. In the flat form, for example, it is easy to clean deep into a low gap between furniture and the floor surface. That is, the height from the floor surface to the suction tool 5 and the pipe body 4 is kept low, and it becomes easy to clean a low place such as under the sofa, so that the operability of the vacuum cleaner 1 can be improved. Further, the suction port body 14 can be inserted deeper into the lower place.

In the flat form, the handle 15 is continuously arranged from the side opposite to the connecting pipe portion 20 of the main body 3 to the upper side of the main body 3. A space is formed between the handle 15 and the outer shell portion 16. The fingers of the hand holding the handle 15 can be inserted into this space. In this way, the handle 15 is continuously arranged from the upper end portion to the lower end portion of the outer shell portion 16. Then, for example, the upper end portion and the lower end portion of the handle 15 are parallel to each other. Further, for example, the intermediate portion of the handle 15 is curvedly connected to the upper end portion and the lower end portion of the handle 15. Therefore, the user can secure an appropriate grip portion according to the situation where cleaning is performed. For example, by holding the wrist in a natural state without bending it, the load on the wrist and hand is reduced.

As shown in FIGS. 12 to 15, in the vacuum cleaner 1 according to this embodiment, the blower nozzle 50 can be attached to and detached from the second exhaust port 32. The blower nozzle 50 is a hollow tubular attachment (accessory). A latch portion 52 is provided on one end side of the blower nozzle 50. The latch portion 52 maintains the coupling state between the second exhaust port 32 of the main body 3 and the blower nozzle 50, and makes it possible to easily release the coupling by the operation of the user.

When the above-mentioned one end side of the blower nozzle 50 is inserted into the second exhaust port 32 of the main body 3, the latch portion 52 is hooked on the edge of the second exhaust port 32, and the second exhaust port 32 and the blower nozzle 50 are connected. The combined state is maintained. When the user pushes the latch portion 52, the coupling state between the second exhaust port 32 and the blower nozzle 50 is released. When the blower nozzle 50 is moved away from the main body 3 in a state where the connection between the second exhaust port 32 and the blower nozzle 50 is released, the blower nozzle 50 can be removed from the main body 3.

A nozzle tip portion 51 is formed on the other end side of the blower nozzle 50. The nozzle tip portion 51 has a tapered shape. An air outlet is formed at the nozzle tip 51.

When the blower nozzle 50 is attached to the second exhaust port 32, the above-mentioned exhaust air passage of the main body 3 passes through the inside of the blower nozzle 50 to the outlet of the nozzle tip 51. When the electric blower 23 is driven in this state, the airflow in the exhaust air passage enters the blower nozzle 50 from the second exhaust port 32. Then, the air flow passes through the blower nozzle 50 and blows out from the nozzle tip 51. In this way, the vacuum cleaner 1 can be used as a blower. When the vacuum cleaner 1 is used as a blower, the user holds the handle 15 and faces the target surface of the nozzle tip portion 51 of the blower nozzle 50. Then, the air ejected from the nozzle tip portion 51 can blow off dust and the like on the target surface.

As shown in FIG. 3, a shutter portion 40 is attached to the second exhaust port 32. The shutter portion 40 is a plate-shaped member and exhibits a lattice shape having a plurality of holes. The shutter portion 40 is attached so that the second exhaust port 32 can be opened and closed. Specifically, in the configuration example described here, the shutter portion 40 is attached to the edge portion of the second exhaust port 32 via the rotation shaft 41 on one side thereof. Then, the shutter portion 40 moves between the position where the second exhaust port 32 is closed and the position where the second exhaust port 32 is opened by rotating inward of the outer shell portion 16 around the rotation shaft 41. It is possible.

A cushion portion 42 is attached to the shutter portion 40. The cushion portion 42 is provided so as to close each of the lattice-shaped holes formed in the shutter portion 40. The cushion portion 42 is made of, for example, a sponge-like material and has breathability. Therefore, even when the shutter portion 40 closes the second exhaust port 32, air can flow through the cushion portion 42 and the shutter portion 40 and through the second exhaust port 32.

However, when the shutter portion 40 closes the second exhaust port 32, the speed of the air flow passing through the second exhaust port 32 becomes slow due to the resistance in the cushion portion 42. Therefore, even if the output of the electric blower 23 is the same, when the shutter unit 40 closes the second exhaust port 32, the shutter unit 40 is compared with the state where the second exhaust port 32 is opened. The amount of exhaust gas from the exhaust port 32 of 2 is reduced.

As shown in FIGS. 12 and 13, when the blower nozzle 50 is attached to and detached from the second exhaust port 32, the blower nozzle 50 is inserted and removed perpendicularly to the opening surface of the second exhaust port 32. That is, the direction of attachment / detachment of the blower nozzle 50 to / from the second exhaust port 32 is perpendicular to the opening surface of the second exhaust port 32. The rotation shaft 41 of the shutter portion 40 is parallel to the opening surface of the second exhaust port 32. Therefore, the rotation shaft 41 is perpendicular to the attachment / detachment direction of the blower nozzle 50 to the second exhaust port 32.

The shutter portion 40 is urged to close the second exhaust port 32 by, for example, a spring or the like. Therefore, as shown in FIG. 3, when the blower nozzle 50 is not attached to the second exhaust port 32, the shutter portion 40 closes the second exhaust port 32.

When the blower nozzle 50 is inserted into the second exhaust port 32, the shutter portion 40 is pushed by the blower nozzle 50 and rotates inward of the outer shell portion 16 around the rotation shaft 41. Then, in a state where the blower nozzle 50 is attached to the second exhaust port 32, as shown in FIG. 14, the shutter portion 40 opens the second exhaust port 32, and the exhaust air passage and the blower nozzle 50 described above of the main body 3 are opened. Completely communicates with the inside of. In this state, the air flow passing through the second exhaust port 32 is not obstructed by the shutter portion 40.

As described above, when the blower nozzle 50 is not attached to the second exhaust port 32, the second exhaust port 32 is closed by the shutter portion 40. Therefore, the displacement from the second exhaust port 32 is suppressed by the shutter unit 40. In other words, when the blower nozzle 50 is not attached to the second exhaust port 32, the shutter unit 40 receives the exhaust amount from the second exhaust port 32 and the blower nozzle 50 to the second exhaust port 32. Reduce than if installed.

Here, the exhaust air passage in the main body 3 leads not only to the second exhaust port 32 but also to the first exhaust port 31. Therefore, the displacement from the first exhaust port 31 increases by the amount of the displacement reduced at the second exhaust port 32. Further, during normal suction cleaning, the user holds the handle 15 and brings the suction port 21 closer to the surface to be cleaned. Since the suction port 21 and the second exhaust port 32 are open in the same direction, the exhaust gas from the second exhaust port 32 is blown out toward the surface to be cleaned. On the other hand, the first exhaust port 31 is not facing the surface to be cleaned.

According to the vacuum cleaner 1 according to this embodiment, when the blower nozzle 50 is not attached to the second exhaust port 32, the displacement from the second exhaust port 32 is reduced, and instead, the second exhaust port 32 is used. By increasing the amount of exhaust from the exhaust port of No. 1, while suppressing a decrease in the suction force during normal suction cleaning by the vacuum cleaner 1, dust is wound up on the surface to be cleaned by the exhaust when the blower nozzle 50 is not in use. Can be suppressed.

At this time, the shutter unit 40 only reduces the amount of exhaust gas from the second exhaust port 32, and does not completely stop the exhaust gas from the second exhaust port 32. By doing so, even when the blower nozzle 50 is not in use, the exhaust gas can be dispersed in both the first exhaust port 31 and the second exhaust port 32, and the decrease in suction force can be further suppressed.

Then, when the blower nozzle 50 is attached to the second exhaust port 32, the shutter portion 40 is opened. Therefore, the amount of exhaust gas from the second exhaust port 32 increases as compared with the case where the blower nozzle 50 is not attached to the second exhaust port 32. Therefore, when the blower nozzle 50 is used, the performance as a blower can be improved by increasing the exhaust air velocity from the second exhaust port 32 to which the blower nozzle 50 is connected.

Here, as described above, the opening area of the second exhaust port 32 is larger than the opening area of the first exhaust port 31. Therefore, when the blower nozzle 50 is used, it is possible to increase the displacement from the second exhaust port 32 as compared with the first exhaust port 31, and the performance as a blower can be further improved.

Further, when the blower nozzle 50 is removed from the second exhaust port 32, the shutter portion 40 closes the second exhaust port 32 by the spring. Then, when the blower nozzle 50 is attached with the second exhaust port 32, the blower nozzle 50 pushes the shutter portion 40 open against the spring, and the second exhaust port 32 is opened. As described above, since the attachment / detachment of the blower nozzle 50 to the second exhaust port 32 and the opening / closing of the second exhaust port 32 by the shutter portion 40 can be linked in a simple configuration, usability can be improved.

As described above, the suction port 21 and the second exhaust port 32 are open in the same direction. Then, the attachment / detachment direction of the blower nozzle 50 to the second exhaust port 32 and the attachment / detachment direction of the pipe body 4 to the suction port 21 are parallel. Therefore, even if the shape of the blower nozzle 50 is a simple straight line, the user can support the main body 3 and use it as a blower in the same manner as during suction cleaning. That is, it is not necessary for the blower nozzle 50 to be provided with a structure for bending the blowout air passage or changing the blowout direction, and the configuration can be simplified.

Further, as shown in FIGS. 2 to 4 and 13, the second exhaust port 32 is arranged closer to the handle 15 than the suction port 21. Therefore, when suction cleaning is performed by the vacuum cleaner 1, the suction port 21 can be easily brought close to the surface to be cleaned without the second exhaust port 32 getting in the way.

Then, as shown in FIGS. 12, 14 and 15, the nozzle tip portion 51 of the blower nozzle 50 attached to the second exhaust port 32 is arranged so as to be separated from the handle 15 by the suction port 21. Therefore, when the vacuum cleaner 1 is used as a blower, the air outlet of the blower nozzle 50 can be easily brought close to the surface to be cleaned without the suction port 21 becoming an obstacle. Therefore, it is possible to obtain an electric vacuum cleaner 1 that is easy to use both as a normal suction cleaner and as a blower.

When the vacuum cleaner 1 is used as a blower, the main body 3 is often supported only by the user's hand without bringing the blower nozzle 50 and the main body 3 into contact with the surface to be cleaned. In the vacuum cleaner 1 of this embodiment, as shown in FIGS. 12, 14 and 15, the longitudinal axis of the blower nozzle 50 attached to the second exhaust port 32 is on the above-mentioned axis of the handle 15. Placed in. Therefore, since the blower nozzle 50 and the air outlet are arranged on the extension line of the above-mentioned axis of the handle 15, the blower nozzle 50 can be easily desired even in an unstable situation in which the main body 3 is supported only by the user's hand. It can be turned in the direction of, and the usability can be improved.

In this embodiment, the handle 15 is continuously formed from the rear end portion to the front end portion of the case portion 18. For example, the rear end and the front end of the handle 15 are parallel. For example, the intermediate portion of the handle 15 is curved and connected to the rear end portion and the front end portion of the handle 15. Therefore, it is possible to secure an appropriate grip portion according to the situation where cleaning is performed. As a result, the user can grasp an easy-to-grip part according to the situation where cleaning is performed.

As shown in FIGS. 16 and 17, the vacuum cleaner 1 of this embodiment is combined with the stand 2 to form a vacuum cleaner system 100. The stand 2 is placed on the floor of the living room, for example. The vacuum cleaner 1 is removed from the stand 2 at the time of use. The stand 2 is, for example, a charging stand. By placing the vacuum cleaner 1 on the stand 2 when not in use, the battery unit 19 of the vacuum cleaner 1 can be charged.

The stand 2 includes a base portion 201, a strut portion 202, and a main body support portion 203. The base portion 201 is a portion serving as a base arranged at the lowermost position of the stand 2. The strut portion 202 is formed upright vertically upward from the upper surface of the base portion 201. The main body support portion 203 is fixed to the intermediate portion of the support column portion 202.

When the vacuum cleaner 1 is placed on the stand 2, the front end side of the suction tool 5 and the side on which the dust collector 17 is arranged are the support columns 202 of the stand 2 when viewed from the pipe body 4 and the connecting pipe portion 20. Directed to. That is, the stand 2 supports the main body 3 of the vacuum cleaner 1 in the above-mentioned upright form from the front end side of the suction tool 5. After the cleaning is completed, the user can place the vacuum cleaner 1 on the stand 2 while moving the vacuum cleaner 1 to the front side of the suction tool 5 as it is. The suction tool 5 is supported by the base portion 201 of the stand 2 when the vacuum cleaner 1 is attached to the stand 2.

In the above, when the vacuum cleaner 1 is used as a blower, a case where a dedicated blower nozzle 50 is attached and used has been described. Regarding this point, as shown in FIG. 18, the pipe body 4 may be attached to the second exhaust port 32 so that the vacuum cleaner 1 can be used as a blower. That is, in this case, the pipe body 4 is removable to both the suction port 21 and the second exhaust port 32. By doing so, the vacuum cleaner 1 can be used as a blower without preparing a dedicated blower nozzle 50.

Further, at this time, it is preferable that the above-mentioned one end side, that is, the side that can be attached to and detached from the suction port 21, can be attached to and detached from the second exhaust port 32. By doing so, when the pipe body 4 is connected to the second exhaust port 32 and used as a blower, the same usage method as when the pipe body 4 is connected to the suction port 21 for suction cleaning may be used. Therefore, usability can be improved.

In the present embodiment, an example in which the dust collecting unit 17 has a cyclone separating device for centrifuging has been described. However, the dust collecting unit 17 is not limited to this as long as it separates the dust from the dust-containing air and accumulates the separated dust. For example, dust and air may be separated by a filter without performing centrifugation. Further, a so-called paper pack type may be used.
