It is a cross-sectional view taken along line JJ shown in b).

The dust case 2 is composed of an outer cylinder 2a and an inner cylinder 200, which will be described later. The outer cylinder 2a has a substantially cylindrical shape, and as described above, the upper surface (cylindrical side surface) is provided with a substantially rectangular inflow port 2b, the front and rear are open, the filter 5 described later is provided at the rear, and the lid 2c is provided at the front. To be equipped. Further, as shown in FIG. 29A, the rear part is divided into a separation part 2a1 that swirls and separates air containing dust sucked from the inflow port 2b, and the front part is divided into a storage part 2a2 that stores the separated dust.

As shown in FIG. 29, the inner cylinder 200 has a substantially cylindrical shape, a cylinder portion 210 having a mesh portion 220 provided at the rear, and a piston portion that pushes out dust when the lid 2c is opened, although the structure is omitted at the front. It is equipped with 240. The piston portion 240 is contained in an umbrella portion 230 provided in front of the tubular portion 210, and the umbrella portion 230 is provided with annular ribs (250a, 250b, 250c). The annular ribs are provided to prevent dust conveyed to the accommodating portion 2a2 from returning to the separation portion 2a1 side. In this embodiment, the annular ribs 250a and 250b are attached to the umbrella portion 230, and the annular ribs 250c are provided. Although it is provided in the piston portion 240, the diameter, position, and number are not limited to this. Among these plurality of annular ribs, the annular rib 250a is provided at a position facing the substantially rectangular inflow port 2b provided in the outer cylinder 2a described above. The inflowing air (including dust) flows around the separating portion 2a1 on the upper side and is directly conveyed to the accommodating portion 2a2 on the lower side with the annular rib 250a as a boundary.

In the absence of the annular rib 250a, the flow swirling around the separating portion 2a1 heads for the accommodating portion 2a2 while swirling, and returns from the accommodating portion 2a2 to the separating portion 2a1 while traveling along the piston portion 240. At that time, the annular ribs 250b and 250c suppress the return of dust, but the dust may return to the separation portion 2a1.

By providing the annular rib 250a as in the present embodiment, the air flow flowing under the annular rib 250a of the inflowing air (including dust) blocks the dust returning from the accommodating portion 2a2 to the separating portion 2a1. Preventing the swirling flow swirling the separating portion 2a1 from being disturbed by the dust returning from the accommodating portion 2a2 to the separating portion 2a1, the swirling flow swirling the separating portion 2a1 is strengthened, the centrifugal separation performance of the dust is improved, and the dust is returned. It is possible to prevent dust from adhering to the mesh portion 220 of the inner cylinder 200.

In this embodiment, the annular rib 250a is provided at a position slightly facing the inflow port 2b, but the present invention is not limited to this, and the position where the inflow port 2b is divided into two may be used. Further, although the annular rib 250a is provided on the umbrella portion 240, it may be provided on the tubular portion 210 provided with the mesh portion 220 instead of the umbrella portion 240.

Further, on the front surface of the dust case 2, a lid 2c that opens and closes when the dust accumulated in the dust case 2 is discarded is rotatably supported via a hinge portion 2d. Further, a lid lock mechanism 2e provided with a release button 2f for unlocking the lid 2c is provided on the upper portion of the lid 2c.

Inside the dust case 2, the filter 5 is housed at the rear end of the outer cylinder 2a in the axial direction.

Further, the release button 2f provided by the lid lock mechanism 2e is located at a position facing from the left side of the vacuum cleaner main body 1 (main body 10), behind the side surface of the main body 10, in other words, at a position not protruding from the side surface of the main body 10. Be prepared. This is because if the release button 2f is provided at a position protruding from the side surface of the main body 10, the lid 2c may be released during cleaning, but the release button 2f is prevented from protruding from the side surface of the main body 10. This is because malfunction can be prevented. For example, the vacuum cleaner body 1 may touch furniture or the like during cleaning. At this time, since the release button 2f is provided on the back side of the side surface of the main body 10, it is unlikely that the lid 2c will open unintentionally without accidentally touching the release button 2f with furniture or the like. The position of the release button 2f provided in the lid lock mechanism 2e is not limited to this, and may be provided at a position facing from the right side of the vacuum cleaner main body 1. By adopting a structure in which the release button 2f can be pressed from the side surface of the main body 10 as in the present invention, the dust in the dust case 2 can be easily discharged by one operation at a waste disposal place such as a trash can.

Further, the dust case removal button 5b shown in FIGS. 4 and 5 described above can be slid in the forward direction indicated by the arrow in the drawing to remove the dust case 2 from the vacuum cleaner main body 1. This makes it possible to carry only the dust case 2 and dispose of it even when the vacuum cleaner main body 1 is standing on the charging stand 70 (during charging). Further, since only the dust case 2 can be removed from the vacuum cleaner main body 1, the dust case 2 can be easily washed with water when the dust case 2 is dirty, so that the dust case 2 can be kept clean. As described above, according to the present invention, it is possible to dispose of dust according to the state in which the dust case 2 is attached to the vacuum cleaner main body 1, the state in which the dust case 2 is removed, and the situation of the user. can do.

Further, the dust case 2 is provided with a removable cleaning brush 2s. The cleaning brush 2s is arranged at a position where it is difficult to see from the outside when the dust case 2 is attached to the vacuum cleaner main body 1. Therefore, it is difficult to remove the cleaning brush 2s during operation, and it is not necessary to store the cleaning brush 2s in a place different from the vacuum cleaner 100.

As shown in FIG. 4, the electric blower 40 is housed in the motor case portion 11 of the main body portion 10. In the motor case portion 11, a main body board 50 (control board) for controlling the vacuum cleaner main body 1 is housed below the electric blower 40.

The electric blower 40 is arranged horizontally so that the rotary drive shaft 40a faces the front-rear direction. Further, the air discharged from the electric blower 40 flows to the main body substrate 50 arranged below the electric blower 40 to cool the main body substrate 50.

The main body board 50 is divided into upper and lower parts and arranged in two stages, and components are mainly mounted on opposite surfaces. Most of the air discharged from the electric blower 40 flows so as to cool the parts (heat generating parts) arranged opposite to each other of the main body substrate 50.

Further, the electric blower 40 and the main body substrate 50 are arranged so as to overlap each other in the vertical direction. Therefore, the dimensions in the front-rear direction can be shortened. Further, the electric blower 40 and the main body substrate 50 are located below the first grip portion 12a1 of the handle portion 12. As a result, when the user grips and operates the grip portion 12a1, the center of gravity of the vacuum cleaner 100 is near the lower side of the first grip portion 12a1. Therefore, when the tip of the vacuum cleaner 100 is used upward, the electric cleaning is performed. The machine 100 can be held stably.

Further, a gap 12c having a width dimension H1 for inserting a hand is formed between the first grip portion 12a1 and the upper surface 11c of the motor case portion 11. Further, a gap 12d having a width dimension H2 wider than the width dimension H1 is formed between the second grip portion 12a2 and the back surface 11d of the motor case portion 11. In this way, when the first grip portion 12a1 is gripped and cleaned, the arm can be held in an extended state, so that the vacuum cleaner 100 can be moved back and forth without firmly gripping the first grip portion 12a1. can. Further, when the second grip portion 12a2 is gripped and cleaned, it is necessary to insert a hand (finger) deeply into the gap 12d and grip it strongly. Therefore, by making the width dimension H2 wider than the width dimension H1. The second grip portion 12a2 can be gripped stably.

Further, the thickness T1 of the first grip portion 12a1 is formed to be thin, and the thickness T2 of the second grip portion 12a2 is formed to be thicker than the thickness T1. That is, the first grip portion 12a1 is formed to be thin, and the second grip portion 12a2 is formed to be thick. In this way, when the second grip portion 12a2 is gripped and cleaned, the thickness T2 of the second grip portion 12a2 can be increased to facilitate deep grip and increase the strength of the second grip portion 12a2. can.

The storage battery 3 can be composed of, for example, a lithium ion battery having high energy efficiency. Further, the storage battery 3 is arranged below the second grip portion 12a2 of the handle portion 12. By providing the storage battery 3 at the rear end of the vacuum cleaner 100 in this way, the center of gravity of the handle portion 12 becomes closer to the second grip portion 12a2. Can be lightened.

The storage battery lock member 13 has a claw portion 13a that is locked to the storage battery 3 on the free end side. Further, the storage battery lock member 13 is arranged so as to surround the back surface of the storage battery 3 from the upper end to the lower end, and is configured so that the claw portion 13a and the lower surface of the storage battery 3 are locked on the lower surface of the rear end of the storage battery 3.

By making the storage battery 3 removable in this way, it becomes easier to replace the storage battery 3 as compared with a non-detachable storage battery. In addition, by preparing a spare storage battery 3 and a charging box capable of charging the spare storage battery 3 as an option, when the storage battery on the main body side of the vacuum cleaner 100 is exhausted, it can be immediately replaced with the spare storage battery 3. , It becomes possible to extend the cleaning time. With such a configuration, it is effective when cleaning a wide floor surface such as a store, for example.

Further, the extension portion 71e is configured so as to project rearward from the connection holding portion 72c and the extension member 80 in the side view of FIG.

Further, the upper surface 83a1 of the holding portion 83a is slightly inclined so as to descend toward the front. Further, the second charging terminal 83 is arranged so as to be inclined along the inclination of the upper surface 83a1.

FIG. 17 is a side view when the vacuum cleaner is attached to the charging stand in a stick state. The direction arrow in FIG. 17 indicates the direction of the charging stand 70 (the same applies to FIG. 18).

As shown in FIG. 17, the vacuum cleaner 100 is charged by being connected to the second charging terminal 83 in the stick state. At this time, the user turns the extension pipe 300 downward while grasping the handle portion 12, and lowers the vacuum cleaner main body 1 from above the second charging terminal 83, so that the main body terminal portion 17 is connected to the second charging terminal 83. Is connected. At this time, since the second charging terminal 83 is formed upward, the main body terminal portion 17 can be reliably connected to the second charging terminal 83 by the own weight of the vacuum cleaner 100.

Further, the dust case 2 is in contact with the holding portion 83b, and the extension pipe 300 is held by the extension pipe holding portion 82c of the extension member 80. Further, a part of the standard suction port 400 is in contact with the mounting surface 71a of the base portion 71. As a result, even when charging with the vacuum cleaner 100 having a high center of gravity, the vacuum cleaner 100 can be stably held in the charging stand 70.

Further, when the vacuum cleaner 100 in the stick state is charged by the charging stand 70, the vacuum cleaner 100 is held in a posture of being tilted forward by an angle α with respect to the vertical direction (vertical direction). By holding the vacuum cleaner 100 in the forward leaning posture in this way, the center of gravity of the vacuum cleaner 100 is closer to the front than when the vacuum cleaner 100 is held upright, so that the vacuum cleaner 100 can be moved forward. You can prevent it from falling backwards.

The charging stand 70 can be used as a stand for storing the vacuum cleaner 100 even when the power cord 76 is not connected and the storage battery 3 is not charged.

FIG. 18 is a side view when the vacuum cleaner is attached to the charging stand in a handy state.

As shown in FIG. 18, the vacuum cleaner 100 is connected to the first charging terminal 73 in the handy state. That is, in the state of charging the stick-state vacuum cleaner 100 shown in FIG. 17, the extension member 80 is attached to the stand portion 72 with the connecting terminal portion 82a facing backward (reverse direction). That is, from the state shown in FIG. 16, the extension member 80 is pulled upward from the extension member 80 until the connection between the first charging terminal 73 (see FIG. 15) and the relay terminal 82 is released. Then, the extension member 80 is rotated around the pipe 81 so that the relay terminal 82 faces the rear side, and is lowered until it comes into contact with the upper surface 72a, so that the state shown in FIG. 18 is obtained.

Then, the extension pipe 300 is removed from the vacuum cleaner 100, and the vacuum cleaner 100 and the standard suction port 400 are directly connected. Then, the first charging terminal 73 is connected to the main body terminal 17 by lowering the main body terminal 17 of the vacuum cleaner 100 to which the standard suction port 400 is connected from above the first charging terminal 73. As described above, in the charging stand 70 of the present embodiment, the extension member 80 can be stored in a different direction, and the vacuum cleaner 100 can be charged in a handy state. Further, since the extension member 80 is not stored in a place different from the charging stand 70, the usability can be improved.

The extension pipe 300 can be stored by being held by the extension pipe holding portion 82c of the extension member 80. In this way, the extension member 80 can be held by the extension tube holding portion 82c of the charging stand 70. Therefore, when the vacuum cleaner 100 is changed from the stick state to the handy state, the removed extension tube 300 is extended. It can be quickly attached to the tube holding portion 82c and stored. Further, when the vacuum cleaner 100 is changed from the handy state to the stick state, the extension pipe 300 can be removed from the extension pipe holding portion 82c and quickly attached to the vacuum cleaner 100. Further, since the extension pipe 300 can be held at a position higher than the floor surface, it can be easily attached and detached by the user, and the usability can be improved. Further, since it is not necessary to store the extension tube 300 in a place different from the charging stand 70, usability can be improved.

FIG. 19 is a cross-sectional view showing a connection state between the main body terminal portion and the first charging terminal.

As shown in FIG. 19, when the main body terminal portion 17 is fitted to the first charging terminal 73, the main body terminal 17d comes into contact with the terminal 73c, and the edge portion 17f of the main body terminal 17d is further lowered to cause the terminal 73c to move. It bends backward and deforms. Since the terminal 73c has a spring property of urging toward the front, the main body terminal 17d and the terminal 73c are maintained in contact with each other while the vacuum cleaner main body 1 is mounted on the charging stand 70. , The storage battery 3 (see FIG. 3) is continuously charged.

Further, since the first charging terminal 73 is unevenly fitted with the main body terminal portion 17, for example, even if the user comes into contact with the vacuum cleaner main body 1 during charging, the main body terminal 17d and the terminal 73c are in a conductive state. (Contact state) is not released. Further, even when the second charging terminal 83 (see FIG. 16) is connected to the main body terminal portion 17, even if the user comes into contact with the vacuum cleaner main body 1 during charging, the main body terminal 17d and the terminal 73c are in a conductive state. (Contact state) is not released.

In the charging stand 70 configured in this way, since the first charging terminal 73 is formed on the upper surface 72a of the stand portion 72, the user's line of sight when the first charging terminal 73 and the main body terminal portion 17 are aligned. Since it is located close to, it becomes easy to insert the main body terminal portion 17 into the first charging terminal 73, and it becomes easy to set the vacuum cleaner main body 1 on the charging stand 70. Further, in the charging stand 70, since the second charging terminal 83 is formed on the upper surface 83a1 (see FIG. 15), when the second charging terminal 83 and the main body terminal portion 17 are combined, it is closer to the user's line of sight. Since it is in the position, it becomes easy to insert the main body terminal portion 17 into the second charging terminal 83, and it becomes easy to set the vacuum cleaner main body 1 on the charging stand 70.

Further, in the charging stand 70, the first charging terminal 73 is formed on the upper surface 72a of the stand portion 72. That is, since the first charging terminal 73 is formed at a position higher than the floor surface, it is difficult for dust to accumulate on the first charging terminal 73, and it is also possible to reduce the amount of dust rising from the floor surface and adhering to the first charging terminal 73. Further, in the charging stand 70, the second charging terminal 83 is formed on the upper surface 83a1 of the extension member 80. That is, since the second charging terminal 83 is formed at a position higher than the floor surface, it is difficult for dust to accumulate on the second charging terminal 83, and it is also possible to reduce the amount of dust rising from the floor surface and adhering to the second charging terminal 83.

Further, in the vacuum cleaner 100 set on the charging stand 70, the first charging terminal 73 and the second charging terminal 83 are located at positions close to the center of gravity of the vacuum cleaner 100 (positions of the electric blower 40 and the storage battery 3). By receiving the vicinity of the center of gravity of the first charging terminal 73 and the second charging terminal 83, the vacuum cleaner main body 1 can be stably held on the charging stand 70 during charging.

Further, by applying the vacuum cleaner 100 to the charging stand 70, the dust case 2 can be charged in a removed state, so that the dust case 2 can be charged even while it is being washed and dried.

Further, when the vacuum cleaner 100 is charged on the charging stand 70 in a handy state, the standard suction port 400 does not come into contact with the mounting surface 71a of the base portion 71 (see FIG. 18). Further, the first charging terminal 73 is directed upward, and the main body terminal portion 17 is connected to the first charging terminal 73 from above. As a result, the weight of the vacuum cleaner 100 can be applied to the first charging terminal 73 in a focused manner, so that the main body terminal portion 17 and the first charging terminal 73 can be reliably connected.

Although not shown, when the vacuum cleaner 100 is charged in the stick state, the main body terminal 17 and the second charging terminal 83 of the vacuum cleaner 100 are connected by the same mechanism as in FIG. NS. Therefore, even when the main body terminal portion 17 and the second charging terminal 83 are connected, the same effect as when the first charging terminal 73 and the main body terminal portion 17 are connected can be obtained.

Further, in the charging stand 70, when charging with the standard suction port 400 connected to the vacuum cleaner 100, the vacuum cleaner 100 can be supported by the mounting surface 71a of the base portion 71, so that the vacuum cleaner 100 is standardized with the first charging terminal 73. It can be supported at two points of the suction port 400, and the vacuum cleaner 100 can be stably held on the charging stand 70.

FIG. 20 is a usage pattern diagram when cleaning the floor surface with a stick-state vacuum cleaner.

As shown in FIG. 20, when the vacuum cleaner 100 is put into a stick state and the vacuum cleaner 100 is projected forward from the user to clean the floor surface, the user uses the second grip portion of the handle portion 12. While gripping 12a2, the vacuum cleaner 100 is moved back and forth. Further, although not shown, when cleaning the floor surface with the vacuum cleaner 100 located beside the user, the user holds the first grip portion 12a1 of the handle portion 12 while performing electricity. Move the vacuum cleaner 100 back and forth. In this way, when the user cleans the floor surface, the position of the handle portion 12 can be changed for cleaning.

FIG. 21 is a usage pattern diagram when cleaning a high place with a stick-state vacuum cleaner.

By the way, in the vacuum cleaner (see Patent Document 1) whose center of gravity is on the tip side when it is in the stick state, when cleaning the vacuum cleaner 100 at a place higher than the floor surface, the user of the vacuum cleaner 100 Since it is necessary to lift the tip upward, it becomes easy to put a burden on the wrist.

Therefore, as shown in FIG. 21, since the electric blower 40 (see FIG. 4) and the storage battery 3 which are heavy objects of the vacuum cleaner 100 are located at a position close to the handle portion 12 (a position close to the hand), the vacuum cleaner 100 The center of gravity G of is closer to the user's hand. As a result, even when the vacuum cleaner 100 is put into a stick state and the vacuum cleaner 100 is cleaned at a place higher than the floor surface, it becomes easy to clean and the usability can be improved. In FIG. 21, the case of cleaning the stairs has been described as an example, but it is also effective when the vacuum cleaner 100 is lifted to clean the panel of the air conditioner or the like.

Next, various applied mouthpieces connected to the vacuum cleaner 100 will be described. Various applied mouthpieces can be connected to and replaced with the electric vacuum cleaner 100 as an accessory for cleaning.

22A and 22B show a cross-sectional view showing a standard mouthpiece to which an opening / closing member is attached. FIG. 22A shows a forward movement, FIG. 22B shows a wall abutment, and FIG. 22C shows a reverse movement. In FIG. 22, the motor for driving the rotary brush and the substrate for controlling the rotary brush are not shown.

As shown in FIG. 22A, the standard mouthpiece 400 includes a mouthpiece case 401, a first brush 402 driven by a motor (not shown), and a second brush 403 that rotates due to friction with the floor surface. It is configured to have.

The mouthpiece case 401 has an open lower surface and a space for accommodating the first brush 402 and the second brush 403. The second brush 403 is arranged with a gap behind the first brush 402.

Further, an opening / closing member 404 is provided on the front surface of the mouthpiece case 401. The opening / closing member 404 has a rotation shaft 404a. Further, the opening / closing member 404 has a protrusion 404b extending perpendicular to the axial direction of the rotation shaft 404a, and an opening / closing body 404c extending from the rotation shaft 404a in the direction opposite to the protrusion 404b. The protrusion 404b is made of a hard plate-like member. The opening / closing body 404c is configured by stacking a brush portion 404c1 on the front side and a rubber plate 404c2 on the rear side in the front-rear direction.

As shown in FIG. 22A, when the standard suction port 400 is advanced, the opening / closing body 404c is counterclockwise due to the frictional force between the brush portion 404c1 and the floor surface and the suction force of the electric blower 40. As it rotates, the lower part of the front surface of the mouthpiece case 401 is opened. By opening the opening / closing body 404c in this way, it becomes possible to suck in large dust (dust) located in front of the standard suction port 400.

As shown in FIG. 22B, when the standard suction port 400 hits the wall, the tip (upper end) of the protrusion 404b first hits the wall. Then, when the standard suction port 400 is further pressed toward the wall, the opening / closing member 404 rotates clockwise due to the pushing force at this time, and the opening / closing body 404c operates forward. When the opening / closing body 404c operates forward, the opening 401a at the lower front surface of the mouthpiece case 401 is closed. With this configuration, dust near the wall (corner) can be sucked in and removed. Further, by moving the standard suction port 400 in the left-right direction, dust near the wall can be removed more reliably.

As shown in FIG. 22C, when the standard suction port 400 is moved backward, the opening / closing body 404c rotates clockwise due to the frictional force between the brush portion 404c1 and the floor surface, and the opening / closing body 404c faces forward. Works on. As a result, the static pressure inside the suction case 401 increases, so that dust can be reliably sucked in.

Further, in the cordless vacuum cleaner 100, the suction power is weaker than that of the vacuum cleaner in which electric power is supplied from a household outlet. For this reason, in the standard mouthpiece 400, the front surface (opening 401a) of the mouthpiece case 401 is opened when moving forward (see FIG. 22A), so that the operating force can be lightened and large dust can be sucked. can. Further, when moving backward (see FIG. 22C), the opening / closing member 404 is closed and the static pressure is increased, so that, for example, sand dust in the carpet can be sucked in firmly. Further, by making the standard suction port 400 smaller than the suction port connected to the vacuum cleaner that supplies power from a household outlet, air leakage from the standard suction port 400 can be reduced, and the static pressure is evenly distributed. It will be easier to spread.

FIG. 23 shows various applied mouthpieces, (a) is a perspective view showing a gap mouthpiece, (b) is a perspective view showing a small mouthpiece, (c) is a perspective view showing a broom-type mouthpiece, and (d) is (d). c) is a plan view.

As shown in FIG. 23A, the gap suction port 500 sucks out dust accumulated between furniture, a gap between furniture and a wall, and the like. Further, the gap suction port 500 has a circular tubular main body connection port 501 connected to the vacuum cleaner 100 at the base end, and a narrow suction port 502 directed to the suction object at the tip end.

As shown in FIG. 23 (b), the small mouthpiece (mini power head) 600 is a substantially smaller version of the standard mouthpiece 400 described above, and it is necessary to clean the same place as the place used by the standard mouthpiece 400. It can be applied to places with physical resistance (sofa, bedding, etc.).

Further, the small mouthpiece 600 includes a mouthpiece case 601 narrower than the standard mouthpiece 400, a rotary brush 602 rotated by a motor M (see FIG. 24A), and a cylindrical scraping brush 603 (see FIG. 24). , Is equipped. Further, the small suction port 600 includes a connection port 604 having a terminal electrically connected to the vacuum cleaner 100.

As shown in FIGS. 23 (c) and 23 (d), the broom-type mouthpiece 700 cleans the rail of the sash, the inside of the drawer in which small items are stored, and the like, and includes a brush body 701 for sweeping dust.
