  FIG. 1 is a perspective view showing a state in which the vacuum cleaner of this embodiment is housed in a charging stand together with accessories.

(Body storage state)
As shown in FIG. 1, the electric vacuum cleaner 100 can perform cleaning by changing to various use modes such as a handy state and a stick state. The charging stand 70 in which the vacuum cleaner 100 is housed is configured to house the vacuum cleaner 100 in a stick state in which an extension tube 300 (accessory) and a standard suction port 400 (accessory) are connected. A part 72 is provided. In addition to the vacuum cleaner 100, the charging stand 70 can house a small suction port 600 (accessory), a broom-type suction port 700 (accessory), and an extension hose 800 (accessory) together. The standard suction port 400 is of a power brush type in which a brush is rotated by a motor.

  FIG. 2 is an exploded view of the vacuum cleaner of the present embodiment.

  As shown in FIG. 2, the vacuum cleaner 100 includes a cleaner body 1 that sucks dust, a dust case 2 that stores sucked dust and is a dust collecting unit that is detachable from the cleaner body 1, and a storage battery 3 ( A power storage device) and an airtight holding member 90.

(Body configuration)
The cleaner main body 1 includes a main body 10, a motor case 11, and a handle 12.

  The main body 10 has a connection port 10a (suction port) to which the extension pipe 300 (see FIG. 1) and the standard suction port 400 (see FIG. 1) are connected. The connection port 10a is formed of the same resin as the main body 10, the motor case 11, the handle 12, and the like. The connection port 10a has a substantially circular opening and is formed facing forward. The connection port 10a can be connected to the extension pipe 300, the standard suction port 400, the small suction port 600, the broom-type suction port 700, and the like (hereinafter, sometimes collectively referred to as an attachment) as accessories. It has become.

  Further, the main body 10 is provided with an introduction pipe 14 (see FIG. 3) to which the dust case 2 is detachably attached and which sends air containing dust sucked from the connection port 10a into the dust case 2.

  The motor case 11 includes an electric blower 40 (see FIG. 6) and a main body substrate 50 (see FIG. 6). In addition, a circular suction port 11a into which clean air collected by the dust case 2 is sucked is formed on the front surface of the motor case portion 11. Further, a body terminal 17 connected to the charging stand 70 is provided below the suction port 11 a on the front surface of the motor case 11.

(Main body and handle)
The handle portion 12 is provided on the rear side of the main body portion 10 and has a grip portion 12a formed in a substantially L shape. The grip portion 12a has a first grip portion 12a1 extending linearly in the front-rear direction and a second grip portion 12a2 extending substantially in the vertical direction in an arc shape. The first grip 12a1 is located above and in front of the second grip 12a2. The second grip portion 12a2 is slightly inclined so that the upper portion faces forward with respect to the vertical direction. Further, the first gripping portion 12a1 and the second gripping portion 12a2 are formed substantially in a rod shape and continuously. In addition, since the inner shape of the second gripping portion 12a2 is formed so that the center expands, it is difficult for the hand to shift to the second gripping portion 12a2 when the first gripping portion 12a1 is gripped. When holding the portion 12a2, it is difficult for the hand to be shifted to the first holding portion 12a1.

  Further, the handle portion 12 is provided with a lock member 13 for locking the storage battery 3. The lock member 13 is formed in a button shape and is swingably supported.

  An operation button 12b is provided on an upper surface of the first grip 12a1 of the handle 12. The operation button 12b includes, for example, three buttons of “strong”, “standard”, and “off”.

  An operation member 20 from which accessories can be removed is attached to the upper surface of the handle portion 12 and forward of the operation button 12b. The operating member 20 has a push button shape, and when the operating member 20 is pressed down, the lock between the main body 10 and the accessory is released, and the accessory can be removed from the main body 10. .

  The operation member 20 is located in front of the upper surface of the first gripper 12a1 and is arranged within a range where the thumb of the gripping hand can reach when the first gripper 12a1 is gripped. The member 20 can be operated. At this time, by arranging the operation member 20 on the front side of the first grip portion 12a1, it is possible to prevent a risk that the accessory is accidentally dropped when the handle portion 12 is gripped during the cleaning operation. A specific range of the arrangement of the operation member 20 is that the operation button 12b is arranged at a position within 55 cm, which is the average length of the thumb of an adult female in Japan, from the front end position of the operation button 12b. The lock between the main body 10 and the accessory can be released with the hand holding the part 12.

  In the present embodiment, the case where the shape of the operation member 20 is a push button is described as an example, but is not limited to this. For example, a trigger shape that can be operated backward may be used, or a lever shape that can be operated in the front-back or left-right direction may be used. However, in the case of the trigger shape, when the vacuum cleaner 100 to which the accessory is connected is cleaned while holding the first grip portion 12a1, a finger is erroneously put on the trigger, and the accessory is attached during the cleaning operation. The push button shape or the lever shape is desirable because the user may fall off and be injured by the user. In the present embodiment, the case where the operation member 20 is the upper surface of the handle portion 12 has been described as an example, but the present invention is not limited to this. As long as the operation can be performed while holding the first holding portion 12a1, it may be disposed on the side surface of the handle portion 12, for example.

(Handy nozzle)
An airtight holding member 90 is attached to a front end of the main body 10. The airtight holding member 90 has a substantially circular cylindrical body 91. The cylindrical body 91 has an elastic portion 91a formed in an annular shape with a soft resin on the distal end side. The tubular body 91 is formed of a material harder than the elastic portion 91a on the base end side, and has a connecting portion 91b connectable to the main body portion 10. The cylindrical body 91 is formed by integrally molding two different members, an elastic portion 91a and a connecting portion 91b. The elastic portion 91a is made of an elastically deformable (flexibly deformable) material such as an elastomer. By attaching such an airtight holding member 90 to the connection port 10a of the cleaner body 1, the entire distal end 90s of the airtight holding member 90 can be brought into close contact with the floor surface, and the suction force is improved as compared with a case where the airtight holding member 90 is not in close contact. Can be done. Further, by forming the connection portion 91b with a hard material, the airtight holding member 90 can be stably attached to the main body 10 without falling off.

  In the present embodiment, the case where the elastic portion 91a is formed of an elastic material such as an elastomer has been described as an example, but the present invention is not limited to this. For example, substantially the entirety of the cylindrical body 91 may be formed of the same material as that of the connecting portion 91b, and the tip of the cylindrical body 91 may be provided with short hairs which are electrostatically planted in a ring shape. Even with such an electrostatic flocking, the tip of the airtight holding member 90 can be brought into close contact with the floor surface as in the case of the elastomer, and the suction force can be improved.

  A long and narrow fitting groove 10b is formed on the outer surface of the connection port 10a of the main body 10. The fitting groove 10b is formed on both left and right sides one by one. A protrusion (not shown) is formed at the base end of the connection portion 91b so as to be engaged and recessed with the fitting groove 10b.

(LED light)
In the main body 10, a light emitting element 10c (see FIG. 2) is provided above the connection port 10a. The light emitting element 10c is configured to emit light forward, that is, toward a surface to be cleaned (floor surface or the like). Further, the distal end surface 10c1 of the light emitting element 10c is located on substantially the same plane as the distal end 10a1 of the connection port 10a.

(battery)
The storage battery 3 supplies electric power to the electric blower 40 (see FIG. 9) and the like, and is configured by a secondary battery such as lithium ion or nickel hydride. The storage battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and can be attached to and detached from the main body 10 by sliding the case 3a in the front-rear direction.

  A terminal 3b connected to the main body 10 is provided on the upper surface of the case 3a. In addition, a slide groove 3c slidably supported by the main body 10 is formed on the upper surface of the case 3a in front of the terminal 3b. A slide rail 3d slidably supported by the main body 10 is formed on the upper surface of the case 3a behind the terminal 3b so as to protrude left and right.

  In addition, an introduction hole 3e into which cooling air for cooling the storage battery 3 is introduced is formed on one side (left side) in the left-right direction (width direction) on the front surface of the case 3a. The introduction hole 3e is formed to be elongated vertically.

  On the front surface of the case 3a, a discharge hole 3f for discharging air after cooling the storage battery 3 is formed on the other side (right side) in the left-right direction (width direction). The discharge hole 3f is formed so as to have a symmetrical shape with respect to the above-described introduction hole 3e.

  On the back surface of the case 3a, there is formed a lock recess 3g in which the lock member 13 is fitted and locked to the main body 10.

  FIG. 3 is a view as seen in the X direction of FIG.

  As shown in FIG. 3, the dust case 2 is of a cyclone type, and has a function of separating air containing dust sucked from the introduction pipe 14 into dust and air, and collecting dust. Further, the dust case 2 is disposed in front of the motor case portion 11 with the axial direction being in the front-rear direction, and has a substantially cylindrical accommodating portion 2a. On the upper surface (side surface) of the dust case 2, a substantially rectangular inflow port 2b (see FIG. 2) connected to the introduction pipe 14 is formed. The air containing dust and dust that has flowed into the inflow port 2b flows around the housing 2a, which is a substantially cylindrical outer cylinder, and the inner cylinder 2h (see FIG. 4) provided concentrically within the housing 2a. A swirling flow is generated, and centrifugal force acts on the dust. The dust is separated into dust and air in the dust case 2, and the air from which the dust is separated is discharged from the rear (rear) of the dust case 2. The inner cylinder 2h has a sliding piston portion 2p (see FIG. 4), and one end of the piston portion 2p is removable.

  On the front surface of the dust case 2, a lid 2c that opens and closes when discarding dust accumulated in the dust case 2 is rotatably supported via a hinge 2d. A lid lock mechanism 2e for unlocking the lid 2c is provided above the lid 2c. The mechanism inside the dust case 2 can be configured based on JP-A-2006-137165. An exhaust port 16 is provided below the motor case 11. The exhaust port 16 has a plurality of slits 16a along the front-back direction, and the plurality of slits 16a are formed side by side in the vertical direction. Although not shown, the exhaust ports 16 are provided on both left and right sides.

  FIG. 4 is a diagram illustrating the structure of the inner cylinder of the dust case 2 that is a dust collecting unit. In this structure, one inner cylinder is used for different outer cylinders to share the inner cylinder.

  4A and FIG. 4B differ in the length of the housing portion 2a which is an outer cylinder. In the present embodiment, the outer cylinder of FIG. 4A is referred to as a first outer cylinder 2a1, and FIG. The outer cylinder of (b) is a second outer cylinder 2a2 shorter than the first outer cylinder 2a1.

  As described above, when the type of the outer cylinder is different for the vacuum cleaner, for example, a stick type and a handy type, it is necessary to manufacture different dust cases, that is, different outer cylinders. Conventionally, the inner cylinder was also manufactured in accordance with the outer cylinder, but in the present invention, one inner cylinder is manufactured, and even if different outer cylinders are shared, the manufacturing cost is reduced. It is. In addition, by sharing the inner cylinder, an effect of preventing a mounting error, such as mounting a different inner cylinder to a different outer cylinder, is also exerted.

  As a specific structure, the dust case 2 which is a dust collecting portion in FIG. 4A is configured by a first outer cylinder 2a1, an inner cylinder 2h, and a filter 5, and FIG. , A second outer cylinder 2a2, an inner cylinder 2h, and a filter 5.

  The first outer cylinder 2a1 has a first connection portion 2i provided with an inner cylinder connection portion 2g connected to the inner cylinder 2h, and the second outer cylinder 2a2 has an inner cylinder connection portion 2g connected to the inner cylinder 2h. The provided second connection part 2f is provided. Here, the same inner cylinder connecting portion is used for the first outer cylinder 2a1 and the second outer cylinder 2a2, but they may be different.

  As shown in FIG. 4A, the first connecting portion 2i is provided with a connecting portion 2g below the outer cylinder top surface, and the second connecting portion 2f is as shown in FIG. 4B. A connecting portion 2g is provided on the upper side of the outer cylinder top surface.

  As described above, by providing the inner cylinder attachment portions such as the first connection portion 2i and the second connection portion 2f corresponding to the respective outer cylinders, the inner cylinder 2h can be shared.

  The housing 2a (the first outer cylinder 2a1 and the first outer cylinder 2a1) houses a dust collection chamber 2t in which the sucked dust is stored, a revolving portion 2r in which the sucked dust turns, and a filter 5. And a filter housing 2u. Although the first connection portion 2i and the second connection portion 2f are provided in the turning portion 2r in FIG. 4, depending on the structure of the dust case 2, they may be provided in the dust collection chamber 2t or the filter storage portion 2u. good.

  FIG. 5 is a schematic diagram of the dust case 2 which is a dust collecting unit.

  In FIGS. 4A and 4B, the inner cylinder mounting portions such as the first connection portion 2i and the second connection portion 2f located on the outer cylinder top surface have a substantially horizontal shape, but in FIG. The inner cylinder mounting portion located on the top surface of the outer cylinder has a substantially conical shape. Specifically, the shape is such that a position 2j at which the outer cylinder housing portion 2a and the inner cylinder 2h are mounted, and an intake port 2k for sucking dust are apex and inclined in a substantially conical shape toward the intake port direction. is there. By adopting such a shape that is inclined in a substantially conical shape, the surface becomes a dust clogging suppression surface, and it is possible to prevent dust from being clogged.

  FIGS. 6A and 6B show another embodiment of FIG. 5, and the shape which is inclined in a substantially conical shape is based on a fulcrum 2m located inside the substantially cylindrical accommodating portion 2a in FIG. 6A. It has a gentle circular shape, that is, a curved shape having a predetermined curvature, and has a concave curved surface with respect to the filter 5 side. In FIG. 6B, the shape that is inclined in a substantially conical shape is a gentle circular shape based on a fulcrum 2n located outside the substantially cylindrical accommodating portion 2a, that is, a curved surface shape having a predetermined curvature. It has a convex curved surface on the 5 arrangement side. have.

  FIG. 7 is a perspective view of the vacuum cleaner of the present embodiment.

  As shown in FIG. 7, in the vacuum cleaner 100, the dust case 2 is attached below the main body 10 and in front of the motor case 11. In this case, when the dust case 2 is mounted on the cleaner body 1, the lid lock mechanism 2e is hidden behind the cleaner body 1. This is because if the lid lock mechanism 2e is provided on the opposite side (outside), the lid lock mechanism 2e may be released during cleaning, but the lid lock mechanism 2e should be hidden behind the cleaner body 1. This can prevent malfunction. For example, when cleaning the sofa or under the bed in a stick state, there is a case where the cleaner main body 1 is brought close to being horizontal with respect to the floor surface. At this time, when the lid lock mechanism 2e is provided on the front side, there is a possibility that the lid lock mechanism 2e is released by contact with the floor surface. The positions of the lid lock mechanism 2e and the hinge portion 2d are not limited to these, and may be provided on the left and right sides of the cleaner body 1.

  The dust case 2 is provided with a maintenance brush 2s (see FIGS. 2 and 3) in a detachable manner. The care 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 cleaner body 1. For this reason, it is hard to come off during driving, and it is not necessary to keep the cleaning brush 2s in a place different from the vacuum cleaner 100.

  When the airtight holding member 90 is attached to the cleaner body 1, the airtight holding member 90 covers the light emitting element 10c. In other words, the inner diameter of the airtight holding member 90 is set so that the light emitting element 10 c is located inside the airtight holding member 9.

  FIG. 8 is a plan view of the vacuum cleaner of the present embodiment.

  As shown in FIG. 8, the connecting portion 91b of the airtight holding member 90 is formed with extending portions 91b1 and 91b1 extending rearward on both left and right sides. A concave portion 91b2 is formed between the left extending portion 91b1 and the right extending portion 91b1 in plan view. The concave portion 91b2 fits with the front end 10d1 of the protrusion 10d formed on the top surface of the distal end of the main body 10. Thereby, the positioning of the airtight holding member 90 in the front-rear direction and the left-right direction with respect to the connection port 10a (see FIG. 2) is performed.

  The introduction pipe 14 formed in the main body 10 is formed to extend once obliquely rightward and backward and then extend downward, and is connected to the inflow port 2b of the dust case 2 (see FIG. 2). Thus, a swirling flow can be generated in the storage portion 2a of the dust case 2, and the dust can be effectively separated by centrifugal force.

  The width of each of the dust case 2 and the storage battery 3 is slightly shorter than the width W of the main body 10. In other words, the configuration is such that the dust case 2 and the storage battery 3 do not protrude from the side of the main body 10. Thus, even if the user holds the left or right hand to perform cleaning, the vacuum cleaner 100 can be smoothly moved in the front-rear direction, and usability can be improved.

  FIG. 9 is a sectional view taken along line VI-VI of FIG. FIG. 9 shows a state in which the airtight holding member 90 is removed from the vacuum cleaner 100.

  As shown in FIG. 9, an electric blower 40 is housed in the motor case 11 of the main body 10. In the motor case 11, a main board 50 (control board) for controlling the cleaner body 1 is accommodated below the electric blower 40.

  The electric blower 40 is disposed horizontally so that the rotary drive shaft 40a faces in the front-rear direction. In addition, the air discharged from the electric blower 40 flows to the main board 50 disposed below the electric blower 40 to cool the main board 50. Further, a part of the air that has cooled the main body substrate 50 cools the storage battery 3.

  The main substrate 50 has an upper substrate 50a and a lower substrate 50b which are vertically divided and arranged in two stages, and various components are mainly provided on opposing surfaces (the lower surface of the upper substrate 50a and the upper surface of the lower substrate 50b). Has been implemented. Most of the air discharged from the electric blower 40 flows so as to cool the components (heating components) of each main body substrate 50 which are opposed to each other. The main body substrate 50 is covered with a flame-retardant resin case 51, and the wind (air) discharged from the electric blower 40 flows from the rear to the front in the resin case 51, and It flows to the storage battery 3 side through the lower side of the bottom surface of the case 51.

  The electric blower 40 and the main body substrate 50 are arranged so as to overlap in the up-down direction. For this reason, the dimension in the front-rear direction can be shortened. In the electric blower 40, the size of the main body 10 in the front-rear direction (total length) can be reduced by forming the motor case portion 11 so as to protrude toward the handle portion 12 side.

  In addition, the electric blower 40 and the main body substrate 50 are located below the first holding portion 12a1 of the handle portion 12. Accordingly, when the user grips and operates the gripping portion 12a1, the center of gravity of the vacuum cleaner 100 is near the lower side of the first gripping portion 12a1. The machine 100 can be stably held.

  A gap 12c having a width H1 for inserting a hand is formed between the first grip 12a1 and the upper surface 11c of the motor case 11. In addition, a gap 12d having a width H2 wider than the width H1 is formed between the second grip 12a2 and the rear surface 11d of the motor case 11. As described above, when cleaning the first grip portion 12a1 by gripping, since the arm can be held in a stretched state, the vacuum cleaner 100 can be moved back and forth without strongly gripping the first grip portion 12a1. it can. In addition, when cleaning by gripping the second grip portion 12a2, it is necessary to insert a hand (finger) deeply into the gap 12d and strongly grip the same, so that the width H2 is made larger than the width H1. The second grip 12a2 can be stably gripped.

  The thickness T1 of the first grip 12a1 is formed to be thin, and the thickness T2 of the second grip 12a2 is formed to be larger than the thickness T1. That is, the first grip 12a1 is formed thin, and the second grip 12a2 is formed thick. As described above, when cleaning by grasping the second grasping portion 12a2, by increasing the thickness T2 of the second grasping portion 12a2, it is easy to grasp deeply, and the strength of the second grasping portion 12a2 can be increased. it can.

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

  The lock member 13 has a button-shaped operation portion 13a formed at the rear end. The operation unit 13a has an arm 13b extending forward, and a front end of the arm 13b is supported by the main body 10. The arm 13b is urged downward by a spring 13c. Thus, when the lock member 13 is fitted and locked in the lock recess 3g, the operation portion 13a is prevented from falling out of the lock recess 3g. When the storage battery 3 is to be removed from the main body 10, the operating portion 13a can be pushed out of the lock recess 3g by pressing the operating portion 13a while repelling the urging force of the spring 13.

  As described above, by making the storage battery 3 detachable, the storage battery 3 can be easily replaced as compared with a storage battery that cannot be removed. In addition, by preparing a spare storage battery 3 and a charging box that can charge 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 is replaced with the spare storage battery 3. The cleaning time can be extended. This configuration is effective, for example, when cleaning a wide floor such as a store.

  As shown in FIG. 9, when a surface passing through the distal end surface of the connection port 10 a of the main body 10 is defined as R <b> 1, the distal end 2 f of the dust case 2 and the surface R <b> 1 (a surface extending in a direction perpendicular to the paper surface) are substantially formed. It is configured to be flush. The tip 2f of the dust case 2 does not protrude forward from the surface R1. Accordingly, even when cleaning is performed without attaching the airtight holding member 90 to the cleaner main body 1, it is possible to perform cleaning while bringing the tip of the connection port 10a into contact with a hard floor surface such as a flooring.

  A filter 5 is accommodated in the dust case 2 at an axially rear end of the accommodating portion 2a. This filter 5 is configured to be folded in a pleated shape, so that the filter area can be increased and the pressure loss due to the filter 5 can be reduced.

  Further, the filter 5 is configured by, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The HEPA filter is an air filter having a particle collection rate of 99.97% or more with respect to particles having a rated air volume of 0.3 μm and an initial pressure loss of 245 Pa or less.

FIG. 10 is a partially enlarged view around the handle of FIG.

  As shown in FIG. 10, the operation member 20 is disposed at a position separated from the fitting portion 21 disposed at the tip of the main body 10. Further, the operating member 20 is linked with the connecting member 20a that slides forward in conjunction with the operation of the operating unit 20, an interlocking member 20b that slides forward in conjunction with the connecting member 20a, and in conjunction with the interlocking member 20b. The fitting member 20c swings.

  The operation member 20 has a substantially rectangular cross section on the upper surface side and a substantially triangular cross section on the bottom surface side.

  The connecting member 20a is disposed below the operating member 20, and has an inclined surface on one end surface that is substantially parallel to the inclined surface of the operating member 20, and has a substantially rectangular shape on the other end surface for pushing the connecting member 20b forward. Have.

  The connecting member 20b is disposed on the front side of the connecting member 20a, and has a substantially rectangular surface on one end surface in contact with the connecting member 20a, and a substantially rectangular surface on the other end surface in contact with the fitting member 20c.

  The fitting member 20c is arranged on the front side of the connecting member 20b, has a shaft portion supported by the main body 10 on a side surface, and a surface that comes into contact with the fitting member 20c above the shaft portion. The fitting portion includes a fitting claw for fitting the accessory and the cleaner body 1 and a receiving portion for a fitting spring 20d for urging the fitting claw downward at the other end. Since the fitting member 20b is urged downward by the fitting spring 20d, when the fitting member 20b is fitted and locked in the recess of the accessory, the fitting between the main body 10 and the accessory is performed. It does not come off.

  When the operating member 20 is pressed, the downward force is converted into a forward force by the connecting member 20a connected to the operating member 20, and the interlocking member 20a is pushed forward. Next, when the force of the connecting member 20a is applied to the connecting member 20b, the fitting member 20c that is in contact with the connecting member 20b receives the front-side force. At this time, since the contact surface between the connecting member 20b and the fitting member 20c is above the shaft portion of the fitting member 20c, the fitting claw of the fitting member 20c comes off while repelling the urging force of the fitting spring 20d, The fitting with the accessory is released.

  FIG. 11 is a side view of the vacuum cleaner of the present embodiment.

  As shown in FIG. 11, the vacuum cleaner 100 has an exhaust port 16 for discharging the sucked air to the outside. The exhaust port 16 is formed at a height position of the main body substrate 50 (see FIG. 9). A louver (air passage switching member) 16b is attached to the outer surface of the exhaust port 16 so as to cover a plurality of slits 16a (see FIG. 3). In FIG. 8, the exhaust port 16 on the near side of the drawing is closed by the louver 6b, and the exhaust port on the opposite side is open.

  The airtight holding member 90 is formed such that a distal end (tip surface) 90s is inclined so as to retreat from an upper portion to a lower portion. The dust case 2 is located rearward with respect to the plane R2 passing through the tip 90s. Thereby, even when the tip 90s of the airtight holding member 90 is brought into contact with a floor surface such as a flooring, the dust case 2 can be prevented from hitting the floor surface.

  FIG. 12 is a sectional view taken along line VIII-VIII of FIG.

  As shown in FIG. 12, the slit 16a of the exhaust port 16 is formed on the substantially semicircular wall surface 16c so as to be divided into right and left. A plurality of slits 16a are formed on the left and right sides of the wall surface 16c. The louver 16b is slidably provided along the wall surface 16c. The louver 16b is provided with ridges 16b1 and 16b1 at both ends in the circumferential direction. In FIG. 12, the louver 16b is located on the left side (the right side in the figure), and the slit 16a on the right side (the left side in the figure) is exposed.

  The main substrate 50 has an upper substrate 50a and a lower substrate 50b which are vertically spaced apart from each other, and is housed in a concave flame-retardant resin case 51. The case 51 has a bottom surface 51a and left and right side surfaces 51b and 51c. For this reason, the upper substrate 50a and the lower substrate 50b cannot be visually recognized from the outside through the slit 16a of the exhaust port 16. Thus, in the vacuum cleaner 100, it is possible to prevent foreign substances from entering from outside the exhaust port 16 and coming into contact with the main body substrate 50.

  The exhaust port 16 is formed so as to communicate with the motor case portion 11, and is configured such that exhaust from the electric blower 40 cools the main body substrate 50 and then is exhausted from the slit 16 a. Further, since the exhaust port 16 is located below the motor case section 11, it is possible to suppress the exhaust from hitting the user. Further, since the left and right directions of the exhaust can be freely changed in the exhaust port 16 of the present embodiment, the exhaust can be prevented from directly hitting the user whether the user is right-handed or left-handed.

  A ridge 16b1 is formed on the surface of the louver 16b so as to protrude outward. Thereby, when moving the louver 16b left and right, it becomes easy to hook a finger on the ridge 16b1, and the operation of moving the louver 16b left and right becomes easy, and the direction of exhaust is changed quickly and easily. be able to.

(Body and handle alignment)
FIG. 13 is a cross-sectional view of FIG. The main body 10 includes a main body case 30 and a main body cover 31 so as to cover the motor case 11. The handle portion 12 has a handle cover 12e on the upper surface and a main body case portion 30 on the lower surface. The main body case 30 and the main body cover 31 have a corner R on the fitting surface on the handle 12 side, and have a structure that does not cause injury when the gripping portion 12a is gripped and a finger hits the fitting surface. At this time, the fitting surface may be the end face of the corner R, but by setting the center of the corner R as shown in FIG. .

  FIG. 14 is a front view of the vacuum cleaner of the present embodiment.

  As shown in FIG. 14, an airtight holding member 90 is provided in the main body 10 so as to surround the connection port 10a. The airtight holding member 90 has an opening 90t having a diameter larger than the diameter D of the connection port 10a. The opening 90t has a length in the up-down direction longer than the length in the left-right direction, and has a substantially elliptical shape when viewed from the axial direction.

  In addition, connection terminals 10u, 10u that are electrically connected to the various attachments described above (see FIG. 1, except for the broom-type suction port 700) are formed above the connection port 10a in the main body unit 10 (the cleaner body 1). Have been. In the main body 10 (cleaner main body 1), a light emitting element 10c is formed further above the connection terminals 10u, 10u. That is, the airtight holding member 90 has not only the connection port 10a but also the opening 90t surrounding the connection terminals 10u, 10u and the light emitting element 10c.

  As described above, the airtight holding member 90 is made larger in diameter than the connection port 10a, and is attached to the outside of the connection port 10a (the outer surface side of the cleaner body 1). The attachment can be attached and detached without detaching it from the main body 1). Thus, when the cleaner body 1 is being cleaned in the stick state, the handy state can be switched by operating the release button 18. Moreover, in this case, since the airtight holding member 90 is still connected to the connection port 10a of the cleaner body 1, the cleaning can be continued with the suction force increased.

  FIG. 15A shows an irradiation state by the light emitting element when the airtight holding member is attached, and FIG. 15B shows an irradiation state by the light emitting element when the airtight holding member is not attached.

  In the comparative example shown in FIG. 15B, the light emitted from the light emitting element 10c is applied to the floor M while diffusing from the connection port 10a. For this reason, when the light is diffused to a high range, the light applied to the floor surface M becomes dim and dark. On the other hand, in the present embodiment shown in FIG. 15A, the light emitted from the light emitting element 10 c is suppressed from being diffused by the airtight holding member 90, and the floor surface is illuminated by the flashlight effect of the airtight holding member 90. M is irradiated in a spot manner. Since the light is narrowed in this way, the light applied to the floor surface M is brighter than that in FIG. Therefore, it is easy to determine the dust on the floor surface M, and the cleaning performance can be improved.

  FIG. 16 is a plan view showing a state in which accessories are connected to the vacuum cleaner.

  As shown in FIG. 16, the vacuum cleaner 100 is configured to be able to connect the extension pipe 300 in a state where the airtight holding member 90 is connected to the cleaner body 1. Thus, the position of the connection port 10a for connecting the extension pipe 300 does not change even when the airtight holding member 90 is connected to the cleaner body 1. Therefore, the total length L connecting the cleaner body 1, the extension pipe 300, and the standard suction port 400 can be reduced. As a result, the position of the standard suction port 400 is close to the user's hand, so that the handling is improved and the usability can be improved.

  In the vacuum cleaner 100 shown in FIG. 16, even when the extension pipe 300 to which the standard suction port 400 is connected is removed from the stick state to be in a handy state, the airtight holding member 90 is still attached to the cleaner body 1. . Therefore, cleaning can be performed in a state where the suction force is increased.

  In the embodiment of FIG. 16, the case where the extension pipe 300 and the standard suction port 400 are connected to the vacuum cleaner 100 has been described as an example. However, the present invention is not limited to this embodiment. For example, the standard suction port 400 can be directly connected to the connection port 10a to be used as the handy vacuum cleaner 100. Thereby, the airtightness with the floor surface is improved by the airtight holding member 90, so that the suction force can be increased.

  As described above, in the vacuum cleaner 100, various accessories (attachments) can be attached and detached while the airtight holding member 90 is attached to the cleaner main body 1, and the cleaning mode is quickly switched to perform cleaning. be able to. Moreover, since the airtight holding member 90 can be left attached to the cleaner main body 1, the handy vacuum cleaner 100 to which the airtight holding member 90 is mounted can perform cleaning while securing a high suction force.

  FIG. 17 is a perspective view showing a charging stand of the vacuum cleaner. The charging stand 70 shown in FIG. 17 is in a state where the vacuum cleaner 100 and all accessories (attachments) are removed. Further, the charging stand 70 will be described with reference to the direction shown in FIG. 17 unlike FIG.

  As shown in FIG. 17, the charging stand 70 includes a base 71 and a stand 72.

  The base portion 71 has a substantially rectangular mounting surface 71a on which the standard mouthpiece 400 (see FIG. 1) is mounted. Further, the base portion 71 has an extending portion 71b extending rearward at the center in the width direction (lateral direction). On the left and right sides of the extension portion 71b, side storage portions 71c and 71d for attaching and storing the small suction port 600 (accessory, attachment) and the broom-type suction port 700 (accessory, attachment) are provided. ing.

  The stand 72 extends vertically (up and down) upward from the extension 71b. In addition, a bulging portion 72a having a thickness (bulging) is formed at an upper portion of the stand portion 72 in front of a lower portion.

  A charging terminal 73 used when charging the vacuum cleaner 100 (see FIG. 1) is provided on an upper surface 72b of the stand section 72. The charging terminal 73 is electrically connected to the cleaner body 1 (see FIG. 2). The charging terminal 73 is a terminal for charging the storage battery 3 and is formed to protrude upward from the upper surface 72b of the stand 72 in the vertical direction.

  A substantially semicircular guide portion 72c is formed on the upper surface 72b of the stand portion 72. The guide portion 72c is a member that guides the cleaner main body 1 (see FIG. 2) to the charging terminal 73 and prevents the cleaner main body 1 from falling down, and is formed to protrude upward from the outer peripheral edge of the upper surface 72b. ing. The guide 72c is formed along the outer peripheral surface of the motor case 11 (see FIG. 2).

  On the right side surface of the stand portion 72, a hook portion 72d for hooking the extension hose 800 (see FIG. 1) is formed.

  FIG. 18 is a side view showing the vacuum cleaner, various accessories, and a charging stand. FIG. 18 shows a state where the extension hose 800 (see FIG. 1) is removed.

  As shown in FIG. 18, the vacuum cleaner 100 is stored in the charging stand 70 with the extension pipe 300 and the standard suction port 400 being connected. At this time, the storage battery 3 is configured not to project from the line L1 extending from the back surface 72a1.

  The small suction port 600 is stored (stored) such that the protrusion 71c2 (see FIG. 17) of the side storage section 71c is inserted into the connection pipe section 600a connected to the connection port 10a (see FIG. 2). Similarly, the broom-type suction port 700 is stored (stored) such that the side storage portion 71c (see FIG. 17) is inserted into a connection pipe (not shown) connected to the connection port 10a (see FIG. 2). Is done.

  The small mouthpiece 600 is a substantially small and simplified version of the standard mouthpiece 400, and is applied to a place (sofa, bedding, etc.) where there is a mental resistance to cleaning the same place used by the standard mouthpiece 400. it can.

  The broom-type suction port 700 is for cleaning rails of a sash, a drawer in which small items are stored, and the like. The broom-type suction port 700 includes a brush body for sweeping dust and a rubber tube for sucking dust. I have. The tube has a suction port that is flexible and can be deformed and does not suck small articles. The broom-type suction port includes a plurality of tubes, is linearly arranged in a plan view, and includes brush bodies on both sides of the tubes.

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

  As shown in FIG. 19, when the main body terminal portion 17 is fitted to the charging terminal 73, the main body terminal 17d comes into contact with the terminal 73c, and further, the edge portion 17f of the main body terminal 17d descends, so that the terminal 73c moves rearward. It bends and deforms. Since the terminal 73c has a spring property for urging forward, the main body terminal 17d and the terminal 73c are maintained in contact with each other while the cleaner main body 1 is mounted on the charging stand 70. Then, charging of the storage battery 3 (see FIG. 2) is continued.

  In addition, since the charging terminal 73 is fitted into the main body terminal portion 17 in an uneven manner, for example, even if the user comes into contact with the cleaner main body 1 during charging, the conduction state between the main body terminal 17d and the terminal 73c (contact state). State) is not released.

  In the charging stand 70 thus configured, since the charging terminal 73 is formed on the upper surface 72b of the stand portion 72, when the main body terminal portion 17 is attached to the charging terminal 73, the charging terminal 73 is located at a position close to the eyes of the user. This makes it easier to insert the main body terminal portion 17 into the charging terminal 73 and to set the cleaner main body 1 on the charging stand 70 easily.

  In the charging stand 70, a charging terminal 73 is formed on an upper surface 72 b of the stand 72. That is, since the charging terminal 73 is formed at a position higher than the floor surface, it is difficult for dust to be deposited on the charging terminal 73, and it is also possible to reduce dust coming up from the floor surface and adhering.

  In the vacuum cleaner 100 (see FIG. 1) set on the charging stand 70, the charging terminal 73 is located at a position close to the center of gravity of the vacuum cleaner 100 (the position of the electric blower 40 and the storage battery 3). By receiving the charging terminal 73, the cleaner main body 1 can be stably held on the charging stand 70 during charging.

  In addition, by applying the vacuum cleaner 100 to the charging stand 70, charging can be performed with the dust case 2 removed, so that charging can be performed even while the dust case 2 is being washed and dried.

  Further, the charging terminal 73 faces upward, and the main body terminal portion 17 is connected to the charging terminal 73 from above. Thereby, the own weight of the vacuum cleaner 100 can be mainly applied to the charging terminal 73, so that the main body terminal portion 17 and the charging terminal 73 can be reliably connected.

  Although not shown, the charging stand 70 can be charged even when the extension tube 300 is removed from the vacuum cleaner 100, or can be charged while the standard suction port 400 is connected.

  Note that the charging stand 70 can be used as a stand for storing the vacuum cleaner 100 even when the power cord 76 (see FIG. 17) is not connected and the storage battery 3 is not charged.

  In addition, when the vacuum cleaner 100 is stored in the charging stand 70, the storage battery 3 is located at the upper end and the lock member 13 is located at the upper end of the storage battery 3, so that the storage battery 3 can be easily attached and detached. it can.

  FIG. 20 is a diagram illustrating a usage pattern when the floor surface is cleaned by the vacuum cleaner in the stick state.

  FIG. 20 shows a state in which the extension pipe 300 and the standard suction port 400 are connected to the vacuum cleaner 100 (while the airtight holding member 90 is mounted) to form a stick state, and the vacuum cleaner 100 is protruded forward from the user to raise the floor surface. This is the case when cleaning. In this case, the user can perform cleaning while moving the vacuum cleaner 100 back and forth while holding the second holding portion 12a2 of the handle portion 12. Although not shown, when cleaning the floor with the vacuum cleaner 100 positioned on the left and right sides of the user, the user holds the first holding portion 12a1 of the handle portion 12 while holding the first holding portion 12a1. The vacuum cleaner 100 can be moved back and forth. As described above, when the user cleans the floor surface, the user can change the position of the handle portion 12 and perform the cleaning.

  FIG. 21 is a diagram illustrating a usage pattern when a high place is cleaned by the vacuum cleaner in the stick state.

  By the way, in a vacuum cleaner whose center of gravity is on the tip side when the stick state is set (see Japanese Patent Application Laid-Open No. 2006-137165), when cleaning the vacuum cleaner at a place higher than the floor surface, the user needs the vacuum cleaner. Since it is necessary to lift the tip upward, a burden is easily applied to the wrist.

  Therefore, in the present embodiment, as shown in FIG. 21, the electric blower 40 (see FIG. 9) and the storage battery 3, which are heavy objects of the vacuum cleaner 100, are at positions near the handle portion 12 (positions near the hand). The center of gravity G of the vacuum cleaner 100 is close to the user. Accordingly, even when the vacuum cleaner 100 is in a stick state and the vacuum cleaner 100 is to be cleaned at a place higher than the floor, it is easy to clean, and the usability can be improved. In FIG. 21, the case where the stairs are cleaned has been described as an example. However, it is also effective when the vacuum cleaner 100 is lifted to clean the panel of the indoor unit of the air conditioner.

  In addition, when the vacuum cleaner 100 is used in a stick state, when removing dust remaining at the corner (corner) of the stairs, the extension pipe 300 and the standard suction port 400 are removed from the vacuum cleaner 100 to be in a handy state. I do. In this case, since the air-tightness holding member 90 is still attached to the vacuum cleaner 100, cleaning can be performed with the suction force increased, and it is possible to prevent dust from being sucked.

  Next, various applied mouthpieces connected to the vacuum cleaner 100 will be described. The vacuum cleaner 100 described above can be cleaned by changing the connection of various kinds of applied suction bodies (attachments) as accessories.

  FIGS. 22A and 22B are cross-sectional views showing a standard mouthpiece to which an opening / closing member is attached, wherein FIG. 22A shows a forward movement, FIG. In FIG. 22, illustration of a motor for driving the rotating brush and a board for controlling the rotating brush is omitted.

  As shown in FIG. 22A, the standard suction port 400 includes a suction case 401, a first brush 402 driven by a motor (not shown), and a second brush 403 that is driven to rotate by friction with a floor surface. , And is configured.

  The suction 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 behind the first brush 402 with a gap.

  An opening / closing member 404 is provided on the front surface of the suction case 401. The opening / closing member 404 has a rotation shaft 404a. The opening / closing member 404 has a projection 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 a direction opposite to the projection 404b. The protrusion 404b is formed of a hard plate-like member. The opening / closing body 404c includes a brush part 404c1 on the front side and a rubber plate 404c2 on the rear side, which are superposed one on the other.

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

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

  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, and the opening / closing body 404c faces forward. Works. As a result, the static pressure in the suction case 401 is increased, so that dust can be reliably sucked.

  Further, in the cordless vacuum cleaner 100, the suction power is weaker than that of a vacuum cleaner in which electric power is supplied from a household outlet. Therefore, in the standard mouthpiece 400, the front surface (opening 401a) of the mouthpiece case 401 is opened at the time of forward movement (see FIG. 22A), so that the operation force can be reduced and large dust can be sucked. Further, when the vehicle moves backward (see FIG. 22C), the opening / closing member 404 is closed and the static pressure is increased, so that, for example, sand dust and the like in the carpet can be sucked firmly. Further, by configuring the standard suction port 400 to be smaller than a suction port connected to a vacuum cleaner supplying electric power from a household outlet, air leakage from the standard suction port 400 can be reduced, and the static pressure can be evenly reduced. It will be easier to get around.

  FIG. 23 is a side view showing the storage state of the extension hose.

  As shown in FIG. 23, the extension hose 800 has a suction port 802 provided with a handle 801 at the distal end, a connection port 803 connected to the cleaner body 1 (see FIG. 2) at the base end, and a connection with the suction port 802. And a bellows tube 804 that connects to the mouth 803. The extension hose 800 in the present embodiment can be housed in the charging stand 70 in a state where the suction port 802 and the connection port 803 are connected and the extension hose 800 is formed in an annular shape. By being stored in this way, the charging stand 70 can stably hold the extension hose 800.

  The extension hose 800 is provided with an electric wire (not shown) for connecting the suction port 802 and the connection port 803. The connection port 803 is provided with a connection terminal electrically connected to the cleaner main body 1, and the suction port 802 is provided with a connection terminal electrically connected to the extension pipe 300, the standard suction port 400, and the small suction port 600. Is provided.

  By using such an extension hose 800 connected to the cleaner main body 1, the position of the small suction opening 600 can be freely adjusted while holding the cleaner main body 1 with one hand and the handle 801 with the other hand. Cleaning is possible while changing. This makes it easier to clean seats, feet, and the like in the vehicle than a vacuum cleaner without an extension hose.

  In addition, when the extension hose 800 is stored in the charging stand 70, the handle 801 is configured to face upward, so that the handle 801 can be easily removed from the charging stand 70. Further, since the direction of the tip 801a of the handle 801 is set obliquely upward and forward, when the user stands in front of the charging stand 70, the handle 801 can be gripped in a normal use state, and the extension hose 800 Easy attachment and detachment.

  FIGS. 24A and 24B show a use state of the extension hose, wherein FIG. 24A shows a vacuum cleaner having a handle portion of the present embodiment, and FIG. 24B shows a vacuum cleaner having a handle portion of a comparative example.

  The vacuum cleaner shown in FIG. 24B includes the cleaner body 1 and a handle 120. The handle part 120 has a structure in which the first grip part 12a1 is not provided on the handle part 12 of the present embodiment. When the extension hose 810 is connected to the cleaner main body 1 having such a handle portion 120, the tip of the cleaner main body 1 faces downward due to the center of gravity. Therefore, as shown in FIG. 24B, it is necessary to increase the length L10 of the extension hose 810.

  On the other hand, the vacuum cleaner 100 of the present embodiment shown in FIG. 24A includes a handle portion 12 provided with a first grip portion 12a1 in addition to the second grip portion 12a2. For this reason, when the extension hose 800 is connected to the cleaner main body 1, the user grips the first grip portion 12a1 so that the tip of the cleaner main body 1 faces forward. Therefore, as shown in FIG. 24A, the length L1 of the extension hose 800 can be configured to be shorter than that in the case of FIG. 24B. Thus, even when the extension hose 800 is stored in the charging stand 70, the extension hose 800 can be stored compactly.

  FIG. 25 is a view showing another usage pattern of the vacuum cleaner.

  As shown in FIG. 25, the vacuum cleaner 100 can be used with the extension hose 300 connected to the extension pipe 300 and the extension pipe 300 connected to the standard suction port 400. In this case, the user holds the first holding portion 12a1 of the handle portion 12 of the cleaner body 1 with one hand, and holds the handle 801 of the extension hose 800 with the other hand, and uses the standard suction port 400 to hold the floor surface.
