The charging stand 70 a that accommodates the vacuum cleaner 100 accommodates the vacuum cleaner 100 in a rod state, and includes a base member 71 , a bracket member 72 , and a holding member 73 . The output plug (DC plug) 81 of the AC adapter 80 for charging the battery 3 mounted in the vacuum cleaner 100 is mounted on the holding member 73, and the output plug 81 is connected to the vacuum cleaner 100 when the vacuum cleaner 100 is set on the charging stand 70a. The main body terminal portion 17 of the battery is connected to enable charging. By doing so, it is possible to completely eliminate the provision of electrical components in the charging stand itself, and it is possible to reduce costs and improve production efficiency. In addition, the electrical connection does not change depending on the presence or absence of the bracket member 72, so that the reliability of the product can be ensured.

The base member 71 has a mounting surface 71a and an extension portion 71b. The placement surface 71a is a substantially rectangular plate-like portion. The protruding portion 71b is a substantially circular truncated portion. The protruding portion 71b is provided so as to be substantially perpendicular to the mounting surface 71a. The center axis of the extension part 71b is provided so that it may be located in the substantially center of the transversal direction of the mounting surface 71a, and the position of approximately 3/4 of the longitudinal direction.

In addition, Fig. 1(b) is a perspective view showing a state in which the vacuum cleaner according to the present embodiment is accommodated in the charging stand in a hand-held state. The charging stand 70b in this state accommodates the vacuum cleaner 100 in a hand-held state. Unlike the charging stand 70a, the stand member 72 is omitted and only the base member 71 and the holding member 73 are provided.

Fig. 2 is an exploded view of the vacuum cleaner according to the present embodiment.

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

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

The main body portion 10 is formed with a connection port 10a (suction port) for connecting the extension tube 300 (refer to Fig. 1 ) and the standard suction port 400 (refer to Fig. 1 ) and the like. The connection port 10a is formed of the same resin as the main body portion 10, the motor case portion 11, the handle portion 12, and the like. In addition, the connection port 10a has a substantially circular opening and is formed to face forward. In addition, the gap/brush switching suction port 110, the extension tube 300, the standard suction port 400, the small suction port 600, the broom-type suction port 700, etc. (hereinafter also collectively referred to as accessories) can be connected to the connection port 10a as accessories.

In addition, the main body 10 is provided with an introduction pipe 14 (refer to Fig. 3 ) to which the dust box 2 is detachably mounted, and which feeds the dust-containing air sucked from the connection port 10a into the dust box 2.

The first grip portion 12a1 is located on the upper side and the front side compared to the second grip portion 12a2. The second grip portion 12a2 is slightly inclined so that the upper portion faces forward with respect to the vertical direction. In addition, the first grip portion 12a1 and the second grip portion 12a2 are substantially rod-shaped and formed continuously. In this way, since the first grip portion 12a1 and the second grip portion 12a2 are both formed in a linear shape, the user can more easily recognize the position of the handle. In addition, since the first gripping portion 12a1 and the second gripping portion 12a2 are bent and connected at an angle close to a right angle, it is difficult for the hand to deviate from the second gripping portion 12a2 when gripping the first gripping portion 12a1. When the two holding parts 12a2 are used, the hand is not easily inclined to the first holding part 12a1.

In addition, the handle portion 12 is provided with a locking member 13 for locking the battery 3 . The locking member 13 is formed in a button type and is supported so as to be swingable.

The cylindrical body 91 is formed by integrally molding two non-identical members, the elastic portion 91a and the connecting portion 91b. In addition, the elastic portion 91a is made of an elastically deformable (flexurally deformable) material such as an elastic body. By attaching such an airtight holding member 90 to the connection port 10a of the cleaner body 1, the entire front end 90s of the airtight holding member 90 can be brought into close contact with the floor, and the suction force can be improved compared with the case of not being in close contact. Further, by forming the connection portion 91b with 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 addition, in the present embodiment, the case where the elastic portion 91a is formed of an elastic material such as an elastic body has been described as an example, but the present invention is not limited to this. For example, substantially the entire cylindrical body 91 may be formed of the same material as that of the connecting portion 91b, and the distal end of the cylindrical body 91 may be provided with short hairs of electrostatically implanted hairs annularly. Even if such electrostatic flocking is provided, the front end of the airtight holding member 90 can be brought into close contact with the ground like the elastic body, and the suction force can be improved.

On the outer surface of the connection port 10a of the main body portion 10, an elongated fitting groove 10b is formed in the longitudinal direction. This fitting groove 10b is formed one on each of the left and right sides. At the base end of the connection portion 91b, a projection portion (not shown) that is engaged with the above-mentioned fitting groove 10b in a concavo-convex manner to be locked is formed.

The light-emitting element 10c is configured to emit light toward the front, that is, the surface to be cleaned (the floor, etc.). In addition, the front end surface 10c1 of the light-emitting element 10c and the front end surface 10a1 of the connection port 10a are located on substantially the same surface.

The battery 3 supplies power to the electric blower 40 (refer to FIG. 6 ) and the like, and is composed of a secondary battery such as lithium ion, nickel metal hydride, or the like. The 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 portion 3b connected to the main body portion 10 is provided on the top surface of the case 3a. In addition, on the top surface of the housing 3a, in front of the terminal portion 3b, there is formed a sliding groove 3c which is slidably supported by the main body portion 10. As shown in FIG. Further, on the top surface of the housing 3a, slide rails 3d and 3d slidably supported by the main body portion 10 are formed to protrude to the left and right sides at the rear of the terminal portion 3b.

In addition, an introduction hole 3e for introducing cooling air for cooling the battery 3 is formed in one (left side) of the left-right direction (width direction) on the front surface of the case 3a. The introduction hole 3e is formed elongated in the vertical direction.

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

In addition, on the rear surface of the case 3a, a locking recess 3g which is fitted with the locking member 13 and locked to the main body portion 10 is formed.

FIG. 3 is a view in the direction X of FIG. 2 .

As shown in Fig. 3, the dust box 2 is of a cyclone type, and has a function of separating the dust-containing air sucked from the introduction pipe 14 into dust and air, and collecting the dust. In addition, the dust box 2 has a substantially cylindrical accommodating portion 2a arranged in front of the motor housing portion 11 with the axial direction being the front-rear direction. Further, on the top surface (side surface) of the dust box 2, a substantially rectangular inflow port 2b connected to the introduction pipe 14 is formed (see Fig. 2 ). The dust-containing air flowing into the inflow port 2b becomes a swirling flow, centrifugal force acts on the dust, and is separated into dust and air in the dust box 2. ) is discharged.

Moreover, the cover 2c which opens and closes when discarding the dust accumulated in the dust collecting box 2 is supported by the front surface of the dust collecting box 2 via the hinge part 2d so that rotation is possible. In addition, on the upper part of the cover 2c, a cover locking mechanism 2e for releasing the lock of the cover 2c is provided. In addition, the mechanism inside the dust box 2 can be configured based on Japanese Patent Application Laid-Open No. 2016-137165.

An exhaust port 16 is provided in the lower part of the motor case portion 11 . The exhaust port 16 has a plurality of slits 16a along the front-rear direction, and the plurality of slits 16a are formed to be aligned in the up-down direction. In addition, although not shown in figure, the exhaust port 16 is provided in the left and right sides.

Fig. 4 is a perspective view of the vacuum cleaner of the present embodiment.

As shown in Fig. 4 , in the vacuum cleaner 100, the dust box 2 is attached below the main body portion 10 and in front of the motor housing portion 11. As shown in Figs. In this case, when the dust box 2 is attached to the cleaner body 1, the lid locking mechanism 2e is hidden on the cleaner body 1 side. This is because if the lid locking mechanism 2e is provided on the opposite side (outer side), there is a risk that the lid locking mechanism 2e will be released during cleaning, but by concealing the lid locking mechanism 2e on the side of the cleaner body 1, it is possible to prevent errors. action. For example, when cleaning the underside of a sofa or a bed in a rod state, the cleaner body 1 may be brought close to the floor horizontally. At this time, when the lid locking mechanism 2e is provided on the front side, there is a possibility that the lid locking mechanism 2e comes into contact with the ground and is released. The positions of the lid locking mechanism 2e and the hinge portion 2d are not limited to this, and may be provided on the left and right with respect to the cleaner body 1.

Moreover, in the dust box 2, the maintenance brush 2s (refer FIG. 2, FIG. 3) is detachably provided. The maintenance brush 2s is arranged in a position where it is difficult to see from the outside when the dust box 2 is attached to the cleaner body 1. As shown in FIG. Therefore, it is not easy to fall off during operation, and it is not necessary to store the maintenance brush for 2 s in a place other than the vacuum cleaner 100 .

In addition, when the airtight holding member 90 is attached to the cleaner body 1, the light-emitting element 10c is covered by the airtight holding member 90. As shown in FIG. In other words, the inner diameter of the airtight holding member 90 is set so that the light-emitting element 10c is located inside the airtight holding member 9. As shown in FIG.

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

As shown in Fig. 5 , the connecting portion 91b of the airtight maintaining member 90 is formed with extending portions 91b1 and 91b1 extending rearward on both the left and right sides. A concave portion 91b2 is formed between the left-side overhang portion 91b1 and the right-side overhang portion 91b1 in plan view. The concave portion 91b2 is fitted with the distal end portion 10d1 of the protruding portion 10d formed on the distal end top surface of the main body portion 10. As shown in FIG. 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 (refer to Fig. 2 ) is performed.

The introduction pipe 14 formed in the main body portion 10 is formed to extend diagonally rearward to the right, and then to extend downward, and is connected to the inflow port 2b (see Fig. 2 ) of the dust box 2. As a result, a swirling flow can be generated in the accommodating portion 2a of the dust box 2, and dust can be effectively separated by centrifugal force.

The respective widths of the dust box 2 and the battery 3 are formed to be slightly shorter than the width W of the main body portion 10 . In other words, the dust box 2 and the battery 3 are configured so as not to protrude from the side of the main body portion 10 . This makes it possible to smoothly move the vacuum cleaner 100 in the front-rear direction regardless of whether the user is cleaning with the right and left hands, and the usability can be improved.

FIG. 6 is a cross-sectional view taken along the line VI-VI of FIG. 5 . In addition, Fig. 6 shows a state in which the airtight holding member 90 is removed from the vacuum cleaner 100. As shown in Figs.

As shown in Fig. 6 , in the motor case portion 11 of the main body portion 10, an electric blower 40 is accommodated. In addition, in the motor casing portion 11, below the electric blower 40, a main body substrate 50 (control substrate) for controlling the cleaner main body 1 is accommodated.

The electric blower 40 is arranged laterally so that the rotational drive shaft 40a faces the front-rear direction. In addition, the air discharged from the electric blower 40 flows to the main body substrate 50 arranged below the electric blower 40, and the main body substrate 50 is cooled. In addition, a part of the air after cooling the main body substrate 50 cools the battery 3 .

The main body 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 mounted mainly on the opposing surfaces (the bottom surface of the upper substrate 50a and the top surface of the lower substrate 50b). Almost all of the air discharged from the electric blower 40 flows so as to cool the components (heat-generating components) of the main body substrates 50 which are arranged opposite to each other. In addition, 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 in the resin case 51 from the rear side to the front side, and then passes through the bottom surface of the resin case 51 . The lower side flows to the side of the battery 3 .

In addition, the electric blower 40 and the main body substrate 50 are arranged so as to overlap in the vertical direction. Therefore, the dimension in the front-rear direction can be shortened. In addition, the electric blower 40 can be shortened in the front-rear direction (overall length) of the main body portion 10 by forming the motor case portion 11 to bulge toward the handle portion 12 side.

In addition, the electric blower 40 and the main body substrate 50 are positioned below the first grip portion 12a1 of the handle portion 12. Thereby, when the user grips and operates the grip portion 12a1, the center of gravity of the vacuum cleaner 100 is in the vicinity of the lower side of the first grip portion 12a1. Therefore, when the vacuum cleaner 100 is used with the front end facing upward, the vacuum cleaner 100 can be stably used. Hold the vacuum cleaner 100.

Further, between the first grip portion 12a1 and the top surface 11c of the motor case portion 11, a gap 12c for inserting a hand having a width dimension H1 is formed. In addition, a gap 12d having a width dimension H2 wider than the width dimension H1 is formed between the second grip portion 12a2 and the rear surface 11d of the motor case portion 11. As shown in FIG. In this way, when the first grip portion 12a1 is gripped for cleaning, the arm can be held in a stretched state. Therefore, the vacuum cleaner 100 can be moved back and forth without strongly gripping the first grip portion 12a1. In addition, in the case of holding the second holding part 12a2 for cleaning, since it is necessary to insert the hand (finger) deeply into the gap 12d and hold it firmly, the width dimension H2 can be made wider than the width dimension H1, and the stability can be stabilized. The second holding portion 12a2 is held firmly.

Moreover, the thickness T1 of the 1st holding part 12a1 is formed thin, and the thickness T2 of the 2nd holding part 12a2 is formed thicker than the thickness T1. That is, the 1st holding part 12a1 is formed thin, and the 2nd holding part 12a2 is formed thick. In this way, when the second grip portion 12a2 is gripped and cleaned, the thickness T2 of the second grip portion 12a2 is made thicker, so that the second grip portion 12a2 can be easily gripped deeply and the strength of the second grip portion 12a2 can be increased.

The storage battery 3 can be constituted by, for example, a lithium-ion battery with high energy efficiency. In addition, the battery 3 is arranged below the second grip portion 12a2 of the handle portion 12. As shown in FIG. In this way, by arranging the battery 3 at the rear end of the vacuum cleaner 100, the center of gravity of the handle portion 12 is close to the second grip portion 12a2, so when the front end of the vacuum cleaner 100 is used upward, the operating feeling can be improved.

The locking member 13 is formed with a button-type operation portion 13a at the rear end portion. The operation portion 13 a has an arm portion 13 b extending forward, and the front end of the arm portion 13 b is supported by the main body portion 10 . Moreover, the arm part 13b is urged|biased downward by the spring 13c. Thereby, when the locking member 13 is fitted into the locking recessed portion 3g and locked, the operation portion 13a is prevented from coming out of the locking recessed portion 3g. In addition, when the battery 3 is removed from the main body portion 10, the operation portion 13a can be disengaged from the lock recessed portion 3g against the urging force of the spring 13 by pressing the operation portion 13a.

In this way, by making the storage battery 3 detachable, the replacement of the storage battery 3 becomes easier compared with the non-detachable storage battery. In addition, by optionally preparing a spare battery 3 and a charging case capable of charging the spare battery 3, when the battery on the main body side of the vacuum cleaner 100 is consumed, it can be replaced with the spare battery 3, so that cleaning can be prolonged. time. This configuration is effective, for example, when cleaning a wide floor such as a store.

As shown in FIG. 6 , when the surface passing through the front end surface of the connection port 10a of the main body portion 10 is designated as R1, the front end 2f of the dust box 2 and the surface R1 (the surface extending in the vertical direction with respect to the paper surface) are constituted. roughly on the same plane. In addition, the front end 2f of the dust box 2 is prevented from protruding further forward than the surface R1. Thereby, even when cleaning in the state where the airtight holding member 90 is not attached to the cleaner body 1, the front end of the connection port 10a can be cleaned so that the front end of the connection port 10a is in contact with a hard floor such as a hard floor.

In the dust box 2, the filter 5 is accommodated at the rear end in the axial direction of the accommodating portion 2a. The filter 5 is formed by being folded in a pleated shape, so that the filter area can be increased and the pressure loss caused by the filter 5 can be reduced.

In addition, the filter 5 is formed of, for example, a high-density HEPA filter (High Efficiency Particulate AirFilter). The HEPA filter is an air filter having a performance of having a particle collection rate of 99.97% or more for particles having a particle size of 0.3 m at a rated air volume, and an initial pressure loss of 245 Pa or less.

(a) and (b) in FIG. 7 and (a) and (b) in FIG. 9 are perspective views of the charging stand 70b and the charging stand 70a in a state in which the vacuum cleaner 100 in the present embodiment has been removed, and FIG. 8 and Figure 10 are their exploded views, respectively. The connection portion between the base member 71 and the bracket member 72 and the connection portion between the bracket member 72 and the holding member 73 have the same shape, and are configured to be recombinable. That is, the shape of the base protrusion-shaped portion 71c of the base member 71 and the shape of the holder protrusion-shaped portion 72b of the holder member 72, which will be described later, are the same shape. The shape is the same shape.

The base member 71 has a substantially rectangular placement surface 71a on which the standard suction port 400 (see Fig. 1 ) is placed. In addition, the base member 71 has a protruding portion 71b extending upward at approximately the center in the width direction (left-right direction) and approximately 3/4 in the longitudinal direction (front-rear direction). A base protrusion-shaped portion 71c that can be attached to the bracket member 72 or the holding member 73 is provided at the front end of the extension portion 71b. In addition, the base member 71 is provided with a counterweight 75 (not shown) inside, so that when the electric vacuum cleaner 100 is mounted on the charging stand 70, the charging stand 70 is not easily toppled.

The bracket member 72 has a substantially cylindrical shape, and the lower end portion thereof is a concave-shaped portion 72h into which the base protrusion-shaped portion 71c of the base member 71 is fitted. In addition, the upper end portion is provided with a bracket protrusion-shaped portion 72b to which the holding member 73 can be attached, and has the same shape as the base protrusion-shaped portion 71c provided on the upper end of the base member 71. As shown in FIG.

By connecting the bracket member 72, the holding member 73, and the base member 71 configured in this way, the base member 71, the bracket member 72, and the holding member 73 form a continuous surface as shown in FIG.

In addition, by connecting the holding member 73 to the base member 71 in a coupled manner, as shown in Fig. 9 , the holding member 73 and the base member 71 form a continuous surface, and a charging stand having a good appearance can be obtained.

That is, the charging stand 70a and the charging stand 70b can be attached to and detached from the AC adapter 80 and the AC adapter 80 for charging the battery 3 of the cleaner body 1, and the base member 71 such as the charging stand 70a, the bracket member 72, and the holding member 73 can be selected. The combination and the combination of the base member 71 and the holding member 73 such as the charging stand 70b are used. It is possible to provide a vacuum cleaner in which the storage method during charging can be selected according to the use state of the vacuum cleaner 100 in which the vacuum cleaner 100 is mainly used in a hand-held state or in a stick state.
