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 accompanying drawings as appropriate.

Fig. 1 (a) is a perspective view showing a state in which the electric vacuum cleaner of the present embodiment is accommodated on the charging stand in a rod state.

The electric vacuum cleaner 100 can be changed to a hand-held state, a pole state, or other various use modes for cleaning. The charging stand 70a for housing the electric vacuum cleaner 100 houses the electric vacuum cleaner 100 in a pole state, and includes a base member 71, a holder member 72, and a holding member 73. An output plug (DC plug) 81 of an AC adapter 80 for charging the battery 3 mounted in the electric dust collector 100 is attached to the holding member 73, and when the electric dust collector 100 is set on the charging stand 70a, the output plug 81 is connected to the main body terminal portion 17 of the electric dust collector 100 to enable charging. Thus, no electric component can be provided on the charging stand itself, and cost reduction and improvement in production efficiency can be achieved. In addition, since the electrical connection does not change depending on the presence or absence of the holder member 72, the reliability of the product can be ensured.

The base member 71 has a mounting surface 71a and an extension portion 71 b. The mounting surface 71a is a substantially rectangular plate-like portion. The protruding portion 71b is a substantially circular truncated cone shaped portion. The protruding portion 71b is provided substantially perpendicular to the mounting surface 71 a. The center axis of the extension portion 71b is provided so as to be located at a position substantially at the center in the short-side direction and substantially about 3/4 in the long-side direction of the placement 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 stand in a hand-held state. The charging stand 70b in this state accommodates the electric vacuum cleaner 100 in a hand-held state, and unlike the charging stand 70a, the stand member 72 is omitted, and only the base member 71 and the holding member 73 are provided.

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 housing 11, and a handle 12.

The main body 10 is formed with a connection port 10a (suction port) for connecting the extension pipe 300 (see fig. 1) and the standard suction port 400 (see fig. 1). 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. The connection port 10a has a substantially circular opening and is formed so as to face forward. The connection port 10a is connected to a gap/brush switching suction port 110, an extension pipe 300, a standard suction port 400, a small suction port 600, a broom suction port 700, and the like (hereinafter, sometimes collectively referred to as "attachment") as attachments.

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

The motor case 11 houses therein an electric blower 40 (see fig. 6) and a main body substrate 50 (see fig. 6). A circular suction port 11a for sucking clean air collected in the dust collecting case 2 is formed in the front surface of the motor housing 11. Further, a body terminal portion 17 connected to the charging stand 70 is provided on the front surface of the motor case 11 below the inlet 11 a.

The grip portion 12 has a grip portion 12a formed in a substantially L shape provided on the rear side of the main body portion 10. The grip portion 12a includes a first grip portion 12a1 linearly extending in the front-rear direction and a second grip portion 12a2 linearly extending in the substantially vertical direction. The first grip portion 12a1 is located on the upper side and the front side of the second grip portion 12a 2. The second grip portion 12a2 is slightly inclined with respect to the vertical direction such that the upper portion faces forward. The first grip portion 12a1 and the second grip portion 12a2 are substantially rod-shaped and are formed continuously. In this way, since the first grip portion 12a1 and the second grip portion 12a2 are both configured linearly, the user can more easily recognize the position of the handle. Further, since the first grip portion 12a1 and the second grip portion 12a2 are connected so as to be bent at an angle close to a right angle, the hand is less likely to be biased toward the second grip portion 12a2 when gripping the first grip portion 12a1, and the hand is less likely to be biased toward the first grip portion 12a1 when gripping the second 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 supported to be swingable.

Further, an operation button 12b is provided on the top surface of the first grip portion 12a1 of the handle portion 12. The operation button 12b is constituted by 3 buttons of "strong", "normal", and "off", for example.

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

Further, an airtight holding member 90 is attached to the distal end of the main body 10. The airtight maintaining 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 formed of a material harder than the elastic portion 91a and connectable to the main body 10 at the proximal end. The cylindrical body 91 is formed by integrally molding 2 different members, 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 airtight holding member is not brought into close contact. Further, by forming the connection 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 is described as an example, but the present invention is not limited thereto. For example, substantially the entire cylindrical body 91 may be formed of the same material as the connecting portion 91b, and short bristles of electrostatic flocking may be provided annularly at the distal end of the cylindrical body 91. Even if such electrostatic flocking is provided, the tip of the airtight holding member 90 can be brought into close contact with the ground surface in the same manner as the elastic body, and the suction force can be increased.

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

In addition, in the main body 10, a light emitting element 10c (see fig. 2) is provided above the connection port 10 a. The light emitting element 10c is configured to emit light toward the front, i.e., a surface to be cleaned (e.g., a floor surface). 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 10 a.

The battery 3 supplies power to an electric blower 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 the case 3a is detachable from the body 10 by sliding in the front-rear direction.

A terminal portion 3b connected to the main body portion 10 is provided on the top surface of the housing 3 a. Further, a slide groove 3c slidably supported by the main body portion 10 is formed in the top surface of the housing 3a in front of the terminal portion 3 b.

Slide rails

3d, 3d slidably supported by the body 10 are formed on the top surface of the housing 3a so as to project laterally and laterally rearward of the terminal portion 3 b.

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

Further, 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) in the front surface of the case 3 a. The discharge hole 3f is formed to have a shape symmetrical to the introduction hole 3 e.

Further, a lock recess 3g that fits into the lock member 13 and locks to the main body 10 is formed on the back surface of the housing 3 a.

Fig. 3 is an X-direction view of fig. 2.

As shown in fig. 3, the dust box 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 the dust. The dust box 2 has a substantially cylindrical housing portion 2a disposed in the front-rear direction of the motor case 11 with respect to the axial direction. In addition, a substantially rectangular inlet 2b (see fig. 2) connected to the inlet pipe 14 is formed in the top surface (side surface) of the dust box 2. The air containing dust flowing into the inlet 2b becomes a swirling 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.

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

An exhaust port 16 is provided at a lower portion of the motor case 11. The exhaust port 16 has a plurality of slits 16a along the front-rear direction, and the plurality of slits 16a are formed in a vertically aligned manner. The exhaust ports 16 are provided on both the left and right sides, not shown.

As shown in fig. 4, in the electric vacuum cleaner 100, the dust box 2 is mounted below the main body portion 10 and in front of the motor casing portion 11. In this case, when the dust box 2 is attached to the cleaner body 1, the cover lock mechanism 2e is hidden on the cleaner body 1 side. This is because, when the cover lock mechanism 2e is provided on the opposite side (outside), there is a risk that the cover lock mechanism 2e is released during cleaning, and malfunction can be prevented by hiding the cover lock mechanism 2e on the cleaner body 1 side. For example, the cleaner body 1 may be horizontally moved close to the floor surface when the lower side of a sofa or a bed is cleaned in a pole state. At this time, when the lid lock mechanism 2e is provided on the front side, the lid lock mechanism 2e may come into contact with the floor surface and be released. The positions of the cover lock mechanism 2e and the hinge portion 2d are not limited to this, and may be provided on the left and right sides of the cleaner body 1.

In addition, a maintenance brush 2s (see fig. 2 and 3) is detachably provided in the dust box 2. 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 brush is not easily detached during operation, and the maintenance brush 2s does not need to be stored in a place other than 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 as to be positioned inside the airtight holding member 9 of the light emitting element 10 c.

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 projecting portions 91b1, 91b1 formed on both left and right sides thereof and projecting rearward. Between the left protruding portion 91b1 and the right protruding portion 91b1, a concave portion 91b2 is formed 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 top surface of the main body 10. This positions the air-tight holding member 90 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 body 10 extends obliquely rightward and rearward and then extends downward, and is connected to the inlet 2b (see fig. 2) of the dust box 2. This can generate a swirling flow in the housing portion 2a of the dust box 2, and can effectively separate dust 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 10. In other words, the dust box 2 and the battery 3 are configured not to protrude from the side of the 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 the left or right hand 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 airtight holding member 90 is removed from the electric vacuum cleaner 100.

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

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

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

The electric blower 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. In the electric blower 40, the motor case 11 is formed so as to bulge toward the grip portion 12, so that the size of the main body 10 in the front-rear direction (overall length) can be reduced.

Further, the electric blower 40 and the main body base plate 50 are located below the first grip portion 12a1 of the handle 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 near the lower side of the first 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.

Further, a gap 12c having a width H1 for inserting a hand is formed between the first grip portion 12a1 and the top surface 11c of the motor case portion 11. Further, a gap 12d of a width dimension H2 wider than the width dimension H1 is formed between the second grip portion 12a2 and the back surface 11d of the motor case portion 11. In this way, when the first grip portion 12a1 is gripped for cleaning, the vacuum cleaner 100 can be moved forward and backward without forcibly gripping the first grip portion 12a1 because the vacuum cleaner can be held with the arm extended. Further, when cleaning is performed by gripping the second grip portion 12a2, since it is necessary to insert a hand (finger) deeply into the gap 12d and grip it with force, the width H2 is made wider than the width H1, whereby the second grip portion 12a2 can be stably gripped.

In addition, the thickness T1 of the first grip portion 12a1 is formed to be thin, and the thickness T2 of the second grip portion 12a2 is formed to be thicker than the thickness T1. That is, the first grip portion 12a1 is formed to be thin, and the second grip portion 12a2 is formed to be thick. In this way, when the second grip portion 12a2 is gripped and cleaned, the second grip portion 12a2 can be made thicker in thickness T2, which facilitates a deeper grip and can increase the strength of the second grip portion 12a 2.

The battery 3 can be formed of, for example, a lithium ion battery with high energy efficiency. The battery 3 is disposed below the second grip portion 12a2 of the grip portion 12. Since the battery 3 is provided at the rear end of the electric vacuum cleaner 100 in this way, the center of gravity of the grip portion 12 is close to the second grip portion 12a2, and therefore, when the electric vacuum cleaner 100 is used with the front end thereof facing upward, the user can feel the feeling of operation easier.

The lock member 13 has a push button type operation portion 13a formed at a rear end portion. The operating portion 13a has an arm portion 13b extending forward, and the tip of the arm portion 13b is supported by the main body portion 10. The arm portion 13b is biased downward by a spring 13 c. Thus, when the lock member 13 is locked by being fitted into the lock recess 3g, the operation portion 13a is not disengaged from the lock recess 3 g. When the battery 3 is detached from the main body 10, the operating portion 13a is pushed and released from the lock recess 3g against the biasing force of the spring 13.

By making the battery 3 detachable in this way, replacement of the battery 3 becomes easier than if the battery were not detachable. In addition, by selectively preparing the spare storage battery 3 and the charging box capable of charging the spare storage battery 3, when the storage battery on the main body side of the electric vacuum cleaner 100 is consumed, the spare storage battery 3 is replaced, and the cleaning time can be extended. With such a configuration, it is effective, for example, in cleaning a wide floor surface such as a store.

As shown in fig. 6, when a surface passing through the front end surface of the connection port 10a of the body 10 is R1, the front 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 is not projected forward from the surface R1. Thus, 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 with the distal end of the connection port 10a in contact with a hard floor surface such as a hard 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 formed by folding in 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 made of, 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 for particles having a particle diameter of 0.3 μm at a rated air volume 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 70b and the charging stand 70a in the state where the electric vacuum cleaner 100 is detached in the present embodiment, and fig. 8 and 10 are exploded views thereof, respectively. 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 are configured to be reconfigurable. That is, a base projection portion 71c of the base member 71 described later is formed in the same shape as a holder projection portion 72b of the holder member 72, and a recessed portion 72h of the holder member 72 is formed in the same shape as a recessed 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) is 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 at a position approximately about 3/4 degrees in the longitudinal direction (front-rear direction). A base projection shape portion 71c to which the holder member 72 or the holding member 73 can be selectively attached is provided at the tip of the extension portion 71 b. Further, the base member 71 is provided with a counterweight 75 (not shown) therein, and when the electric vacuum cleaner 100 is attached to the charging stand 70, the charging stand 70 is less likely to fall down.

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 portion 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 can be attached, and the shape thereof is the same as that of a base projection-shaped portion 71c provided at the upper end of the base member 71.

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

Further, by coupling and connecting the holding member 73 and the base member 71, 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 attach and detach the AC adapter 80 and the AC adapter 80 for charging the battery 3 of the cleaner body 1, and 2 kinds of combinations of the base member 71 and the holder member 72 and the holding member 73 as the charging stand 70a and the base member 71 and the holding member 73 as the charging stand 70b can be selected for use. An electric vacuum cleaner in which the storage mode during charging can be selected according to the use state of the electric vacuum cleaner 100, such as whether the electric vacuum cleaner 100 is used mainly in a hand-held state or in a pole state, can be provided.

The holder member 72 may be divided into a plurality of members. In this case, it is possible to provide an electric vacuum cleaner capable of selecting a preferred height.

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

Fig. 11 (a) and (b) are enlarged views of the output plug 81 mounting portion of the AC adaptor 80 of the holding member 73. The holder 73 has an opening 73i on the top surface 73b of the holding member 73, to which the output plug 81 of the AC adapter 80 can be attached, and the output plug 81 can be attached to serve as a charging stand for charging the electric vacuum cleaner 100. The guide portions 73a, which are projections serving as guide portions when the main body is attached, are provided on the left and right sides of the output plug 81, and a load is not easily applied to the output plug 81.

The output plug 81 is attached so as to protrude upward from the top surface 73b of the holding member 73, and has guide portions 73a of a substantially rectangular parallelepiped shape on both sides thereof. The guide portion 73a has a chamfered portion formed at the front end.

A substantially rib-shaped guide portion 73e is formed on the front surface 73d of the holder portion 73. The guide portion 73c is a member for guiding the output plug 81 to the cleaner body 1 (see fig. 2) and preventing the cleaner body 1 from falling down, and is formed to protrude forward from both end edge portions of the front surface 72 b. Further, a projection 73f is provided at the lower portion thereof, and is formed so as to be fitted to the bottom of the dust box 2 attached to the cleaner body 1, thereby further preventing the cleaner body 1 from falling down.

The guide portion 73a has a front inclined portion. The front inclined portion is an inclined portion provided from the top surface to the front surface of the guide portion 73 a. The front inclined portion at the front end of the guide portion 73a is used when the electric dust collector 100 is stored in the charging stand 70. When the electric vacuum cleaner 100 is stored in the charging stand 70, the electric vacuum cleaner 100 is gradually moved toward the charging stand 70 from the front thereof. When the dust box 2 approaches, the front surface 73d of the holder 73 comes into contact with it. When the electric vacuum cleaner 100 is moved downward while maintaining this state, it can be moved along the substantially prismatic guide portion 73a and guided to a position where the output plug 81 and the input socket 17b are in good contact with each other. Therefore, the output plug 81 can be stably brought into contact with the input socket 17 b.

In the embodiment, the front inclined portion of the guide portion 73a is inclined at 45 degrees with respect to the horizontal. This allows the electric vacuum cleaner 100 to smoothly move along the substantially prismatic guide portion 73a by its own weight. Further, since the surface area contacted by the front inclined portion is increased as compared with the case where the front inclined portion is not present, the effect of preventing damage or breakage of the inclined portion of the guide portion 73a and the bracket portion 73 can be achieved. Here, the angle is not limited to 45 degrees, and may be an inclination of 1 degree or more and less than 90 degrees as long as the effect of smooth guidance can be achieved. Further, since the effect of more smooth guiding can be achieved when the inclination is small, and the surface area of contact increases when the inclination is large, the effect of further reducing the load on the inclined portion of the guide portion 73a and the bracket portion 73 can be achieved. Further, in order to secure strength, flange portions may be provided in the holder member 72 and the holding member 73.

Fig. 12 is a perspective view showing a state in which the 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.

As shown in fig. 12, a fitting recess 17a into which a guide portion 73a (see fig. 11) 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 socket 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. In addition, the present embodiment employs a type in which the AC adapter is directly connected to the receptacle, but a type in which the AC adapter 80 is connected to the receptacle via a cable with a plug may 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 and charged. With this configuration, even when there is no place to place the charging stand, the battery can be charged in a space-saving manner.

Fig. 15 (a) is a perspective view showing a state in which 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 with the cleaner body 1 directed downward, whereby the body terminal portion 17 is connected to the output plug 81. At this time, since the output plug 81 is formed to face upward, the main body terminal 17 can be reliably connected to the output plug 81 by the own weight of the electric vacuum cleaner 100.

Fig. 16 is a central sectional view of the holder portion 73. In the embodiment, the height of the guide vertical portion 73a1 of the guide portion 73a is 9.5mm, and the height from the guide vertical portion 73a1 to the guide flat end portion 73a2 is set to 5.8mm, which is about 1.6 times the height. Accordingly, the fitting recess 17a has a large area in contact with the guide vertical portion 73a1, and the cleaner body 1 is not easily detached from the charging stand 70 even if the user accidentally touches the cleaner body 1 in a state where the cleaner body 1 is attached to the charging stand 70. The height of the vertical guide portion 73a1 is about 1.6 times the height from the vertical guide portion 73a1 to the flat guide end 73a2, but the ratio of the height of the vertical guide portion 73a1 to the height from the vertical guide portion 73a1 to the flat guide end 73a2 may be greater than 1.6 times or smaller as long as the effect that the cleaner body 1 is not easily detached from the charging stand 70 is achieved. If the height of the guide vertical portion 73a1 is higher than the height from the guide vertical portion 73a1 to the guide flat end portion 73a2, the area of the fitting recess 17a in contact with the guide vertical portion 73a1 increases, so that the cleaner body 1 can be made less likely to fall off from the charging stand 70. If the height of the guide vertical portion 73a1 is lower than that from the guide vertical portion 73a1 to the guide flat end portion 73a2, the inclined portion of the guide portion 73a is enlarged, the cleaner body 1 is easily made to meet the inclined portion of the guide portion 73a, and an effect that the user easily connects the cleaner body 1 to the charging stand 70 can be achieved.

In addition, in a state where the output plug 81 is attached to the holder portion 73, the upper portion of the output plug 81 is located at a position lower than the guide flat end portion 73a, and when the cleaner body 1 is attached to the charging stand 70, the cleaner body 1 is prevented from contacting the output plug 81, and the damage of the output plug 81 can be prevented.

Fig. 17 is a sectional view showing a connection state between the main terminal portion and the output plug 81.

As shown in fig. 17, when the main terminal portion 17 is fitted to the output plug 81, the main terminal 17d comes into contact with the terminal 73c, and the edge portion 17f of the main terminal 17d is lowered, so that the terminal 73c is bent rearward. Since the terminal 73c has elasticity for biasing forward, the main body terminal 17d and the terminal 73c are kept in contact with each other and the battery 3 is continuously charged when the cleaner main body 1 is attached to the charging stand 70.

Further, since the output plug 81 is fitted to the main body terminal portion 17 in a concave-convex manner, even when the 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 top surface 72b of the holder member 72, when the main body terminal portion 17 is attached to the output plug 81, it is positioned close to the line of sight of the user, and therefore, it is easy to insert the main body terminal portion 17 into the output plug 81, and it is easy to set the cleaner main body 1 on the charging stand 70.

In the charging stand 70, the output plug 81 is formed on the top surface 72b of the holder member 72. That is, since the output plug 81 is formed at a position higher than the floor surface, it is difficult to deposit dust on the output plug 81, and it is possible to reduce the dust from being lifted from the floor surface and adhering thereto.

In addition, since the output plug 81 is formed at a position higher than the ground surface, it is possible to prevent the output plug 81 from being damaged by the user stepping on the output plug 81 by mistake or the like.

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 (positions of the electric blower 40 and the battery 3), the vicinity of the center of gravity is supported by the output plug 81, and the cleaner body 1 can be stably held on the charging stand 70 during charging.

Further, since the electric vacuum cleaner 100 can be charged in a state where the dust box 2 is removed by applying it to the charging stand 70, the dust box 2 can be charged even during cleaning and drying.

The output plug 81 is directed upward, and the main terminal portion 17 is connected to the output plug 81 from above. Accordingly, the self weight of the electric vacuum cleaner 100 can be made to act on the output plug 81 with a high degree of importance, and therefore the main body terminal portion 17 and the output plug 81 can be reliably connected.

Grooves

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

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

The charging stand 70 can also be used as a stand for storing the electric vacuum cleaner 100 when the power cord 76 is not connected to the AC adapter 80 (see fig. 18) and the battery 3 is not charged.

In addition, 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 housing table capable of housing a vacuum cleaner, if the vacuum cleaner housing table includes the base member 71, the holder member 72, and the holding member 73, only the vacuum cleaner housing table in a state in which the base member 71 is connected to the holding member 73 can house the vacuum cleaner in the first state (the hand-held state), and the vacuum cleaner housing table in a state in which the base member 71 is connected to the holder member 72 to the holding member 73 can house the vacuum cleaner in the second state (the pole state), an effect can be achieved in which the housing mode at the time of housing can be selected in accordance with the use state of the vacuum cleaner 100.

Fig. 18 shows a state where the extension pipe 300 and the standard suction port 400 are connected to the electric vacuum cleaner 100 (in a state where the airtight holding member 90 is mounted) in a pole state, and the electric vacuum cleaner 100 is protruded to the front of the user to clean the floor. In this case, the user can move the electric vacuum cleaner 100 forward and backward for cleaning while holding the second grip portion 12a2 of the grip portion 12. In addition, although not shown, when the electric vacuum cleaner 100 is to be placed on both the left and right sides of the user to clean the floor, the user can move the electric vacuum cleaner 100 forward and backward while holding the first grip portion 12a1 of the handle portion 12. Thus, when the user cleans the floor, the user can perform cleaning while changing the position of the handle portion 12.

In the electric vacuum cleaner having the center of gravity on the front end side in the pole state (see japanese patent application laid-open No. 2016-.

Then, in the present embodiment, as shown in fig. 19, since the electric blower 40 (see fig. 6) and the battery 3, which are heavy objects of the electric vacuum cleaner 100, are located at positions close to the handle portion 12 (positions close to the hand), the center of gravity G of the electric vacuum cleaner 100 is close to the hand of the user. This makes it easier to clean even when the electric vacuum cleaner 100 is in a pole state and the electric vacuum cleaner 100 is used to clean a place higher than the floor, thereby improving usability. In fig. 19, the case of cleaning a step is described as an example, and the present invention is effective also in the case where the electric vacuum cleaner 100 is lifted to clean a panel of an indoor unit of an air conditioner.
