Detailed Description

Hereinafter, a mode for carrying out the present invention (hereinafter referred to as "embodiment") will be described in detail with reference to the drawings as appropriate.

Fig. 1(a) is a perspective view showing a state in which the electric vacuum cleaner of the present embodiment is housed in the charging stand in a lever type (スティック) state.

The electric vacuum cleaner 100 can be changed to various use states such as a hand-held (ハンディ) state and a stick-type state to perform cleaning. The charging stand 70a for housing the electric vacuum cleaner 100 is configured to house the electric vacuum cleaner 100 in a bar-type state, and includes a base member 71, a holder member 72, and a holding member 73. The output plug 81 of the AC adapter 80 for charging the battery 3 attached to the electric vacuum cleaner 100 is attached to the holding member 73, and when the electric vacuum cleaner 100 is set on the charging stand 70a, the output plug 81 can be connected to the input jack 17b of the electric vacuum cleaner 100 to be charged. By adopting such a structure, any electric component is not required to be arranged on the charging stand, so that the cost can be reduced and the production efficiency can be improved. In addition, the electrical connection is not changed regardless of whether the holder member 72 is provided, and thus reliability of the product can be ensured.

The base member 71 has a mounting surface 71a and an extending portion 71 b. The mounting surface 71a is a substantially rectangular plate-shaped portion. The extension 71b is a substantially truncated cone-shaped portion. The extension portion 71b is provided substantially perpendicular to the mounting surface 71 a. The central axis of the extending portion 71b is positioned substantially at the center in the short side direction and substantially at the right and left sides 3/4 in the longitudinal direction of the mounting surface 71 a.

Fig. 1(b) is a perspective view showing a state in which the electric vacuum cleaner of the present embodiment is stored in a charging station in a hand-held state. The charging stand 70b in this state accommodates the vacuum cleaner 100 in a hand-held state, and unlike the charging stand 70a, the stand member 72 is omitted and is constituted only by the base member 71 and the holding member 73.

As shown in fig. 2, the electric vacuum cleaner 100 includes a cleaner body 1, a dust box 2 (dust collecting device), a battery 3 (power storage device), and an airtight holding member 90.

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

The main body 10 is formed with a connection port 10a (suction port) connected to an extension pipe 300 (see fig. 1), a standard suction port 400 (see fig. 1), and the like. 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 to face forward. The gap/brush switching nozzle 110, the extension pipe 300, the standard suction port 400, the small suction port 600, the broom-type suction port 700, and the like (hereinafter, may be collectively referred to as "attachments") as attachments can be connected to the connection port 10 a.

The dust box 2 is detachably attached to the main body 10, and an inlet pipe 14 (see fig. 3) for sending air containing dust sucked from the connection port 10a into the dust box 2 is provided.

The motor case 11 is provided with a motor fan 40 (see fig. 6) and a main body board 50 (see fig. 6). A circular suction port 11a is formed in the front surface of the motor case portion 11, and clean air collected by the dust case 2 is sucked into the suction port 11 a. A main body terminal portion 17 connected to the charging stand 70 is provided on the front surface of the motor case portion 11 below the suction port 11 a.

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 includes: a1 st grip portion 12a1 linearly extending in the front-rear direction; and a2 nd grip portion 12a2 extending linearly in a substantially vertical direction. The 1 st grip portion 12a1 is located above and in front of the 2 nd grip portion 12a 2. The 2 nd grip portion 12a2 is slightly inclined so that the upper portion is forward in the vertical direction. The 1 st grip 12a1 and the 2 nd grip 12a2 are substantially rod-shaped and continuously formed. In this way, by configuring both the 1 st grip portion 12a1 and the 2 nd grip portion 12a2 to be linear, the user can easily recognize the position of the handle. Since the 1 st grip portion 12a1 and the 2 nd grip portion 12a2 are connected so as to be bent at an angle close to a right angle, the hand does not easily slip to the 2 nd grip portion 12a2 when gripping the 1 st grip portion 12a1, and the hand does not easily slip to the 1 st grip portion 12a1 when gripping the 2 nd grip portion 12a 2.

The handle portion 12 is provided with a lock member 13 for locking the battery 3. The lock member 13 is formed in a push button type and is swingably supported.

A hand operation portion 12b is provided on the upper surface of the 1 st grip portion 12a1 of the handle portion 12. The hand operation portion 12b is constituted by 3 buttons of "strong/turbo", "standard/turbo", and "off", for example.

A release button 18 is provided at an upper portion of a front end of the main body 10, and the release button 18 is operated when an accessory such as an extension pipe 300 (see fig. 1) is removed. By pushing the release button 18, the lock between the main body 10 and the accessory can be released, and the accessory can be detached from the main body 10.

An airtight holding member 90 is attached to the distal 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 of a soft resin in a ring shape on the distal end side. The cylindrical body 91 has a connecting portion 91b at the base end side, which is connectable to the main body 10, and the connecting portion 91b is formed of a material harder than the elastic portion 91 a. The cylindrical body 91 is formed by integrally forming 2 members of different kinds, i.e., the elastic portion 91a and the connecting portion 91 b.

The elastic portion 91a is made of an elastically deformable (flexibly deformable) material such as an elastic body. By attaching the 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 can be increased as compared with the case where the member is not brought into close contact. By forming the connecting portion 91b of a hard material, the airtight holding member 90 can be attached to the main body portion 10 in a stable state 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, the cylindrical body 91 may be formed of substantially the same material as the connecting portion 91b, and the short electrostatic flocking hairs may be annularly provided at the distal end of the cylindrical body 91. Even if such electrostatic flocking (bristles) is provided, the tip of the airtight holding member 90 can be brought into close contact with the floor surface in the same manner as the elastic body, thereby improving the suction force.

A fitting groove 10b elongated in the longitudinal direction is formed in the outer surface of the connection port 10a of the body 10. The fitting grooves 10b are formed in 1 piece on each of the left and right sides. At the root end of the connecting portion 91b, a locking protrusion (not shown) is formed to be engaged with the engaging groove 10b in a concave-convex manner.

The main body 10 is provided with a light emitting element 10c (see fig. 2) above the connection port 10 a. The light emitting element 10c is configured to emit light forward, that is, toward a surface to be cleaned (floor surface, etc.). The distal end surface 10c1 of the light emitting element 10c is substantially flush with the distal end 10a1 of the connection port 10 a.

The battery 3 supplies electric power to the electric fan 40 (see fig. 6) and the like, and is formed of a secondary battery such as lithium ion or nickel hydrogen. The battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and is attached to and detached from the main body 10 by sliding the case 3a in the front-rear direction.

On the upper surface of the case 3a, a terminal portion 3b connected to the main body portion 10 is provided. Further, a slide groove 3c slidably supported by the main body portion 10 is provided on the upper surface of the cartridge 3a in front of the terminal portion 3 b.

Slide rails

3d, 3d slidably supported by the main body 10 are formed on the upper surface of the case 3a so as to project to the left and right behind the terminal portion 3 b.

An introduction hole 3e through which cooling air for cooling the battery 3 can be introduced is formed in the front surface of the case 3a on one side (left side) in the left-right direction (width direction). The introduction hole 3e is formed to be elongated in the vertical direction.

A discharge hole 3f for discharging air after cooling the battery 3 is formed in the other side (right side) in the left-right direction (width direction) on the front surface of the case 3 a. The discharge hole 3f is formed to have a shape bilaterally symmetrical to the introduction hole 3 e.

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

Fig. 3 is a view when viewed along an arrow in the X direction of fig. 2.

As shown in fig. 3, the dust box 2 is of a cyclone (cyclone) type, and has a function of separating air containing dust sucked from the inlet pipe 14 into dust and air, and collecting the dust. The dust box 2 is disposed in front of the motor box portion 11 in the axial direction, and has a substantially cylindrical housing portion 2 a. A substantially rectangular inlet port 2b (see fig. 2) connected to the inlet pipe 14 is formed in the upper surface (side surface) of the dust box 2. The air containing dust flowing into the inlet 2b becomes a swirling air flow, centrifugal force acts on the dust, the dust is separated into dust and air in the dust box 2, and the air from which the dust is separated is discharged from the rear (back) of the dust box 2.

A cover 2c is rotatably supported by a hinge portion 2d on the front surface of the dust box 2, and the cover 2c is opened and closed when dust accumulated in the dust box 2 is discarded. A cover locking mechanism 2e for releasing the locking of the cover 2c is provided on the upper portion of the cover 2 c. The mechanism inside the dust box 2 can be configured as described in japanese patent application laid-open No. 2016-137165.

An exhaust port 16 is provided at the lower portion of the motor case portion 11. The exhaust port 16 has a plurality of slits 16a in the front-rear direction, and the plurality of slits 16a are formed to be aligned in the vertical direction. The exhaust ports 16 are provided on the left and right sides, but are not illustrated here.

As shown in fig. 4, in the electric vacuum cleaner 100, the dust box 2 is attached to the lower side of the main body 10 and the front side of the motor box 11. In this case, when the dust box 2 is attached to the cleaner body 1, the cover locking mechanism 2e is hidden on the cleaner body 1 side. This is because, in the case where the cover lock mechanism 2e is provided on the opposite side (outside), there is a problem that the cover lock mechanism 2e is released during cleaning, but erroneous operation can be prevented by hiding the cover lock mechanism 2e on the cleaner main body 1 side. For example, when cleaning the underside of a sofa, a bed, or the like in a pole-type state, the cleaner body 1 may be brought close to the floor surface in parallel. 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 cover lock mechanism 2e and the hinge portion 2d are not limited to the above-described configuration, and may be provided on the left and right sides with respect to the cleaner body 1.

The dust box 2 is detachably provided with a maintenance brush 2s (see fig. 2 and 3). The maintenance brush 2s is disposed at a position where it is not easily visible from the outside when the dust box 2 is attached to the cleaner body 1. Therefore, the maintenance brush 2s is not easily detached during operation, and it is not necessary to store the maintenance brush in a place different from the electric vacuum cleaner 100.

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

Fig. 5 is a plan view of the electric vacuum cleaner of the present embodiment.

As shown in fig. 5, the connecting portion 91b of the airtight holding member 90 has extending portions 91b1, 91b1 formed on both left and right sides thereof and extending rearward. A concave portion 91b2 is formed between the left extending portion 91b1 and the right extending portion 91b1 in a plan view. The concave portion 91b2 is fitted into the front end portion 10d1 of the protruding portion 10d formed on the front end upper surface of the main body 10. Thereby, the airtight holding member 90 is positioned in the front-rear direction and the left-right direction with respect to the connection port 10a (see fig. 2).

The introduction pipe 14 formed in the main body 10 extends obliquely rearward to the right and then extends downward, and is connected to the inlet 2b (see fig. 2) of the dust box 2. This can generate a swirling air flow in the housing portion 2a of the dust box 2, and effectively separate dust by centrifugal force.

The width of each of the dust box 2 and the battery 3 is formed slightly shorter than the width W of the main body 10. In other words, the dust box 2 and the battery 3 do not protrude from the side surface of the main body 10. Accordingly, the electric vacuum cleaner 100 can be smoothly moved in the front-rear direction regardless of whether the user holds the cleaner with one of the left and right hands to perform cleaning, and the usability can be improved.

Fig. 6 is a sectional view taken along line VI-VI of fig. 5. Fig. 6 shows a state where the air-tightness maintaining member 90 is removed from the electric vacuum cleaner 100.

As shown in fig. 6, the motor case portion 11 of the main body portion 10 houses a motor fan 40. In the motor case portion 11, a main body board 50 (control board) for controlling the cleaner main body 1 is housed below the electric fan 40.

The electric fan 40 is disposed laterally so that the rotary drive shaft 40a faces the front-rear direction. The air discharged from the electric fan 40 flows to the main body substrate 50 disposed below the electric fan 40, and cools the main body substrate 50. A part of the air after cooling the body substrate 50 cools the battery 3.

The main body substrate 50 has an upper substrate 50a and a lower substrate 50b arranged in upper and lower 2 layers, and various components are mounted mainly on the surfaces (the lower surface of the upper substrate 50a and the upper surface of the lower substrate 50 b) facing each other. Almost all of the air discharged from the electric fan 40 flows so as to cool the components (heat generating components) disposed opposite to each other on the respective main substrates 50. The main body board 50 is covered with a flame-retardant resin case 51, and wind (air) discharged from the electric fan 40 flows from the rear side to the front side in the resin case 51, and then flows through the lower side of the bottom surface of the resin case 51 to the battery 3 side.

The electric fan 40 and the main body board 50 are arranged to overlap each other in the vertical direction. Therefore, the dimension in the front-rear direction can be shortened. The electric blower 40 can reduce the size of the main body 10 in the front-rear direction (overall length) by forming the motor case portion 11 so as to bulge toward the grip portion 12.

The electric blower 40 and the main body board 50 are located below the 1 st grip portion 12a1 of the grip portion 12. Accordingly, when the user grips the grip portion 12a1 and operates it, the center of gravity of the electric vacuum cleaner 100 is located in the vicinity of the lower side of the 1 st grip portion 12a1, and therefore, when the electric vacuum cleaner 100 is used with the distal end thereof facing upward, the electric vacuum cleaner 100 can be stably held.

A gap 12c having a width H1 into which a hand is inserted is formed between the 1 st grip portion 12a1 and the upper surface 11c of the motor case portion 11. A gap 12d having a width H2 larger than the width H1 is formed between the 2 nd grip portion 12a2 and the back surface 11d of the motor case portion 11. In this way, when cleaning is performed by gripping the 1 st grip 12a1, the electric vacuum cleaner 100 can be moved in the front-rear direction without strongly gripping the 1 st grip 12a1 because the wrist can be held in an extended state. When the second grip portion 12a2 is gripped and cleaned, since it is necessary to insert a hand (finger) deeply into the gap 12d and strongly grip it, the second grip portion 12a2 can be gripped stably by making the width H2 larger than the width H1.

The thickness T1 of the 1 st grip portion 12a1 is formed to be thin, and the thickness T2 of the 2 nd grip portion 12a2 is formed to be larger than the thickness T1. That is, the 1 st grip portion 12a1 is formed to be thin, and the 2 nd grip portion 12a2 is formed to be thick. In this way, when cleaning is performed by gripping the 2 nd grip portion 12a2, the 2 nd grip portion 12a2 can be easily gripped deeply by increasing the thickness T2 of the 2 nd grip portion 12a2, and the strength of the 2 nd grip portion 12a2 is improved.

The battery 3 can be formed of, for example, a lithium ion battery having high energy efficiency. The battery 3 is disposed below the 2 nd grip portion 12a2 of the handle portion 12. Since the center of gravity of the grip portion 12 can be brought close to the 2 nd grip portion 12a2 by providing the battery 3 at the rear end of the electric vacuum cleaner 100 in this way, the operational feeling can be reduced when the electric vacuum cleaner 100 is used with the front end facing upward.

The lock member 13 has a push button type operation portion 13a formed at a rear end portion. The operation portion 13a includes a wrist portion 13b extending forward, and the front end of the wrist portion 13b is supported by the main body portion 10. The arm 13b is biased downward by a spring 13 c. Thus, when the lock member 13 is fitted into the lock recess 3g and locked, the operation portion 13a does not come out of the lock recess 3 g. When the battery 3 is detached from the main body 10, the operating portion 13a can be disengaged from the locking recess 3g by pressing the operating portion 13a against the biasing force of the spring 13.

By making the battery 3 detachable in this way, the battery 3 can be easily exchanged as compared with a case where the battery is not detachable. Further, by preparing the backup battery 3 and the charging box capable of charging the backup battery 3 as options, when the main body side battery of the electric vacuum cleaner 100 is consumed, the cleaning time can be extended by replacing the backup battery 3. By adopting such a configuration, it is effective in cleaning a wide floor surface of a store or the like, for example.

As shown in fig. 6, when a surface passing through the distal end surface of the connection port 10a of the main body 10 is R1, the distal end 2f of the dust box 2 is substantially flush with a surface R1 (a surface extending in the vertical direction with respect to the paper surface). The front end 2f of the dust box 2 does not protrude forward of the surface R1. With such a configuration, even when cleaning is performed in a state where the air-tightness holding member 90 is not attached to the cleaner body 1, cleaning can be performed while the distal end of the connection port 10a is brought into contact with a hard floor surface such as a floor.

In the dust box 2, a filter 5 is housed at the rear end in the axial direction of the housing portion 2 a. The filter 5 is folded into a pleated shape, and the filter area can be increased and the pressure loss caused by the filter 5 can be reduced.

The Filter 5 is, for example, a High-density HEPA Filter (High Efficiency Particulate Air Filter). The HEPA filter is an air filter having a performance as described below, a particle trapping rate of 99.97% or more with respect to particles having a particle diameter of 0.3 μm at a rated air flow rate, and an initial pressure loss of 245Pa or less.

Fig. 7(a) and (b) and fig. 9(a) and (b) are perspective views of the charging stand 70a and the charging stand 70b in a state where the electric vacuum cleaner 100 according to the present embodiment is detached, and fig. 8 and 10 are exploded views thereof. The connecting portion between the base member 71 and the holder member 72 and the connecting portion between the holder member 72 and the holding member 73 have the same shape and can be replaced. That is, a base projection shape portion 71c of the base member 71 described later has the same shape as a holder projection shape portion 72b of the holder member 72, and a recessed shape portion 72h of the holder member 72 has the same shape as a recessed shape portion 73h of the holding member 73.

The base member 71 has a substantially rectangular placement surface 71a on which the standard suction port 400 (see fig. 1) can be placed. The base member 71 has an extending portion 71b extending upward at a position substantially at the center in the width direction (left-right direction) and substantially at the left-right position 3/4 in the longitudinal direction (front-rear direction). A pedestal protrusion 71c to which the bracket member 72 or the holding member 73 can be selectively attached is provided at the tip of the extension 71 b. The base member 71 is provided with a weight 75 (not shown) therein, and the charging stand 70 is not easily fallen down when the electric vacuum cleaner 100 is attached to the charging stand 70.

The holder member 72 has a substantially cylindrical shape, and a lower end portion thereof is a concave portion 72h fitted to the base projection 71c of the base member 71. The upper end portion is provided with a holder projection-shaped portion 72b to which the holding member 73 is attachable, which is the same shape as the base projection-shaped portion 71c provided at the upper end of the base member 71.

By coupling the holder member 72, the holding member 73, and the base member 71 configured as described above, as shown in fig. 7, a surface where the base member 71 is continuous with the holder member 72 and the holding member 73 is configured, and the charging stand 70 having a good appearance can be obtained.

By coupling the holding member 73 and the base member 71, as shown in fig. 9, a surface where the holding member 73 and the base member 71 are continuous is formed, and a charging stand having a good appearance can be obtained.

That is, the AC adapter 80 and the AC adapter 80 for charging the battery 3 of the cleaner body 1 can be attached to and detached from the charging stand 70a and the charging

stand

70b, and 2 combinations of the base member 71 such as the charging stand 70a, the combination of the holder member 72 and the holding member 73, and the combination of the base member 71 such as the charging stand 70b and the holding member 73 can be selected and used. In this way, it is possible to provide an electric vacuum cleaner capable of selecting a storage mode at the time of charging according to a use state of the electric vacuum cleaner 100 (mainly, a state in which the electric vacuum cleaner 100 is used in a hand-held state and a state in which the electric vacuum cleaner 100 is used in a stick-type state).

The holder member 72 may be configured as a member that can be disassembled into a plurality of pieces. In this case, it is possible to provide a vacuum cleaner including a charging stand of which a preferred height can be selected.

The holding member 73 may be provided with a hole through which it can be fixed to a wall surface by a screw or the like.

Fig. 11(a) and (b) are enlarged views of the mounting portion of the output plug 81 of the AC adaptor 80 of the holding member 73. An opening 73i to which the output plug 81 of the AC adapter 80 is attached is provided in the upper surface 73b of the holding member 73, and the output plug 81 is attached to the opening 73i, whereby the vacuum cleaner can be used as a charging stand for charging the vacuum cleaner 100. The output plug 81 is attached so as to protrude upward from the upper surface 73b of the holding member 73, and has guide portions 73a of a substantially rectangular parallelepiped shape on the left and right sides thereof, which serve as guides when the body is attached. With this guide portion 73a, it is made difficult for a load to be applied to the output plug 81. The guide portion 73a has a chamfered portion formed at the tip.

A substantially rib-shaped guide portion 73e is formed on the front surface 73d of the holding member 73. The guide portion 73e is a member for guiding the cleaner body 1 (see fig. 2) to the output plug 813 and preventing the cleaner body 1 from falling down, and is formed to protrude forward from both end edge portions of the front surface 73 d. The projection 73f is provided at the lower portion thereof, and is fitted to the bottom of the dust box 2 attached to the cleaner body 1, whereby the falling of the cleaner body 1 can be further prevented.

Fig. 12 is a perspective view showing a state in which a main body terminal portion of the electric vacuum cleaner connected to the output plug 81 of the AC adapter 80 is viewed from the dust box side upward.

As shown in fig. 12, a fitting recess 17a into which a guide portion 73a (see fig. 11(a) and (b)) of the charging stand 70 is fitted is formed in the main body terminal portion 17 of the cleaner main body 1. An input jack 17b connected to an output plug 81 of the AC adapter 80 is disposed at the center in the fitting recess 17 a. The input jack 17b is connected to a terminal (not shown) connected to the terminal portion 3b of the battery 3 by a lead wire (not shown).

Fig. 13 is an external view of the AC adapter 80. A type of directly connecting the AC adapter to the receptacle is adopted in the present embodiment, but a type of connecting from the AC adapter 80 main body to the receptacle via a cord with a plug may also be used.

Fig. 14 is an external view showing a state in which the AC adapter 80 is directly connected to the electric vacuum cleaner for charging. With this configuration, even when there is no place where the charging stand is placed, the charging can be performed in a space-saving manner.

Fig. 15(a) is a perspective view showing how the AC adapter 80 is attached to the holding member of the charging stand, and fig. 15(b), (c), and (d) are central sectional views.

The user lowers the cleaner body 1 from above the output plug 81 by moving the cleaner body 1 downward, and connects the body terminal portion 17 to the output plug 81. At this time, since the output plug 81 is formed to face upward, the main body terminal portion 17 can be reliably connected to the output plug 81 by the self weight of the electric vacuum cleaner 100.

Fig. 16 is a sectional view showing a connection state between the main terminal portion and the output plug 81. When the guide portion 73a of the charging stand 70 is fitted into the fitting recess 17a of the main body, the output plug 81 located at the center thereof is fitted into the input socket 17b, and the AC adapter 80 is electrically connected to the electric vacuum cleaner 1. While the cleaner body 1 is mounted on the charging stand 70, the output plug 81 and the input jack 17b are kept in contact with each other, and the battery 3 is continuously charged.

Since the output plug 81 is fitted to the main body terminal portion 17 in a concave-convex manner, even if a user touches the cleaner main body 1 during charging, for example, the conductive state (contact state) between the main body terminal 17d and the terminal 73c is not released.

In the charging stand 70 configured as described above, since the output plug 81 is formed on the upper surface 72b of the holder member 72, when the main body terminal portion 17 is attached to the output plug 81, the main body terminal portion 17 is easily inserted into the output plug 81 because it is positioned close to the line of sight of the user, and the cleaner main body 1 is easily mounted on the charging stand 70.

In the charging stand 70, an output plug 81 is formed on the upper surface 72b of the holder member 72. That is, since the output plug 81 is formed at a position higher than the floor surface, dust is less likely to accumulate on the output plug 81, and dust rising from the floor surface and adhering to the output plug 81 can be reduced.

In the electric vacuum cleaner 100 mounted on the charging stand 70, since the output plug 81 is located at a position close to the center of gravity of the electric vacuum cleaner 100 (the position of the electric blower 40 and the battery 3), the cleaner body 1 can be stably held on the charging stand 70 during charging by the output plug 81 being subjected to the vicinity of the center of gravity.

Since the electric vacuum cleaner 100 can be charged with the dust cartridge 2 detached by mounting it on the charging stand 70, the charging can be performed even when the dust cartridge 2 is being cleaned and dried.

The output plug 81 is directed upward, and the main terminal portion 17 is connected to the output plug 81 from above. With such a configuration, the weight of the electric vacuum cleaner 100 can be applied to the output plug 81 with high priority, and therefore the main body terminal portion 17 and the output plug 81 can be reliably connected.

Grooves

72g, 73g in which an output cable 82 of the AC adapter 80 can be disposed are provided on the back surfaces of the holder member 72 and the holding member 73.

The charging stand 70 can be stored and charged with the standard suction port 400 and other accessories connected to the electric vacuum cleaner 100, but is not shown here.

The charging stand 70 can be used as a stand when the electric vacuum cleaner 100 is stored even when the AC adapter 80 is not connected and the battery 3 is not charged.

In a state where the electric vacuum cleaner 100 is stored in the charging stand 70, the battery 3 is positioned at the upper end, and the lock member 13 is positioned at the upper end of the battery 3, so that the battery 3 can be easily attached and detached.

In other words, in the vacuum cleaner storage stand capable of storing the vacuum cleaner, the vacuum cleaner storage stand has the base member 71, the holder member 72, and the holding member 73, the vacuum cleaner storage stand in a state in which only the base member 71 and the holding member 73 are connected can store the vacuum cleaner in the first state (the hand-held state), and the vacuum cleaner storage stand in a state in which only the base member 71, the holder member 72, and the holding member 73 are connected can store the vacuum cleaner in the second state (the pole-type state).

Fig. 17 is a schematic view of a cleaning operation of the electric vacuum cleaner in a stick-type state.

Fig. 17 shows a state in which the extension pipe 300 and the standard suction port 400 are connected to the electric vacuum cleaner 100 (with the airtight holding member 90 attached) in a pole-type state, and the electric vacuum cleaner 100 is extended to a position in front of a user to clean a floor surface. In this case, the user can perform cleaning while gripping the 2 nd gripping part 12a2 of the handle part 12 and moving the vacuum cleaner 100 forward and backward. When the electric vacuum cleaner 100 is placed on the left and right sides of the user to clean the floor surface (not shown), the user can move the electric vacuum cleaner 100 forward and backward while holding the 1 st grip portion 12a1 of the grip portion 12. Thus, when the user cleans the floor surface, the position of the handle portion 12 can be changed to clean the floor surface.

However, in the electric vacuum cleaner having the center of gravity located on the front end side when the electric vacuum cleaner is in the lever-type state (see japanese patent application laid-open No. 2016-137165), when cleaning a place having a relatively high floor surface by the electric vacuum cleaner, the user needs to lift the electric vacuum cleaner with the front end thereof facing upward, and thus a load is easily applied to the wrist.

In the present embodiment, as shown in fig. 18, the electric blower 40 (see fig. 6) and the battery 3, which are the heavy objects of the electric vacuum cleaner 100, are located close to the grip portion 12 (close to the hand), and therefore the center of gravity G of the electric vacuum cleaner 100 is close to the hand of the user. Accordingly, even when the electric vacuum cleaner 100 is set in the pole-type state and the electric vacuum cleaner 100 is used to clean a place higher than the floor surface, the cleaning is easy and the usability can be improved. In fig. 18, the case of cleaning a step is described as an example, but the case of lifting the electric vacuum cleaner 100 to clean a panel or the like of an indoor unit of an air conditioner is also effective.

Fig. 19 shows the hand operation portion 12 b. The hand operation unit 12b is constituted by 3 buttons, for example, a "strong turbine" button 12b1, a "standard turbine" button 12b2, and a "off" button 12b 3. In a state where the electric blower is stopped (in a state where the other button is not pressed after the "off" button 12b3 is pressed), the "strong" operation mode or the "normal" operation mode can be operated by pressing the "strong turbine" button 12b1 or the "normal turbine" button 12b 2. The "strong" operation mode enables operation with a large attraction force as compared with the "standard" operation mode. Further, in the "strong" operation mode and the "standard" operation mode, the button of the hand operation portion corresponding to each operation mode is pressed again (the "strong turbine" button 12b1 is pressed in the "strong" operation mode, and the "standard/turbine" button 12b2 is pressed in the "standard" operation mode), whereby the "turbine" operation mode in which the attraction force is temporarily increased (for example, about 5 seconds) can be operated. This makes it possible to immediately enter a mode for temporarily increasing the suction force during cleaning, and to operate garbage or the like that has entered the deep part of the carpet while temporarily increasing the suction force. As a method for increasing the suction force, for example, there is a method of increasing the input to the electric blower.

The attraction of each "turbo" mode operating by pressing the "strong/turbo" button 12b1 or the "standard/turbo" button 12b2 twice is the same. Thus, in both the "strong" operation mode and the "normal" operation mode, the operation can be performed in the same "turbine" operation mode by pressing the button once. Thus, even during the cleaning in each operation mode, the mode for temporarily increasing the suction force can be immediately entered.

When the operation mode of the "turbine" is finished (when the operation mode is finished for about 5 seconds, for example), the operation mode is returned to the previous operation mode before the button is pressed. For example, when the "strong turbine" button 12b1 is pressed in the "strong" operation mode to operate in the "turbine" operation mode, the operation mode returns to the "strong" operation mode, and when the "standard turbine" button 12b2 is pressed in the "standard" operation mode to operate in the "turbine" operation mode, the operation mode returns to the "standard" operation mode.

Here, the continuous use time in the case of operating only in the "strong" operation mode or the "standard" operation mode is shortened by the time corresponding to the operation time due to the operation in the "turbine" operation mode (for example, when operating once in the "turbine" operation mode, the continuous use time in the other operation mode is shortened by about 5 seconds.
