Further, in this embodiment, the ring-shaped main wheel 101 is disposed by utilizing the periphery of the thick filter storage chamber 127. The cross-sectional shape of the main wheel 101 is such that the ground contact surface is thin. Has a substantially triangular shape,
The triangular slope and the arc surface of the filter cover are continuous to form an outer peripheral surface of a substantially spherical body.

Further, a ring-shaped sliding surface which contacts the ring-shaped wheel base 126 is formed inside the main wheel 101, and a thin fixing rib projecting inward is formed outside the ring-shaped sliding surface. In this embodiment, by holding the fixing rib between the end of the wheel base 126 and the end of the outer periphery of the wheel cover 133, it is possible to obtain good running performance without rattling.

In FIG. 5, as described above, in this embodiment, the periphery of the cleaner main body 100 has a double structure. That is, the dust collection chamber 133 surrounded by the inner wall surface 124 and the partition wall 121 is formed at the front part of the main body, and the dust collection chamber 133 surrounded by the inner wall surface 124 and the partition wall 121 is formed at the rear part of the main body. An air blowing chamber 114 is formed. Then, the outer space 51 is formed which continuously surrounds both sides and the rear of the dust collecting chamber 113 and the air blowing chamber 114 surrounded by the inner wall surface 124.

Here, in FIG.
Is divided by a communication passage 164. As shown in FIG. 4, the ventilation passage 164 and the outer space 51 are vertically divided into two stages, and FIG. 5 shows a portion of the ventilation passage 164. This is due to the cross section.

Further, on both sides of the outer space 51, the filter storage portions 127 communicated with the ventilation passage 164 are arranged. As shown in FIG. 15, the cleaning filter 112 folded into a flat box shape is stored in the filter storage portion 127 so as to be positioned outside by the positioning rib 165. Thereby, the ventilation path 1
The exhaust air guided to 64 is spread over the entire clean filter 112 by the space formed by the positioning ribs 165, so that the entire clean filter 112 can be used efficiently.

The exhaust air discharged to the outside from the filter storage chamber 127 is reversed by the wheel cover space 133a, and is adjacent to the outside air through the passage 135 formed around the filter storage chamber 133. It is led to the space 51. And the exhaust air led to this outer space 51 is
Air is exhausted from the cleaner body 100 through an exhaust port 166 formed in the outer wall 123 around the wheel base 126.

On the other hand, in this embodiment, as described with reference to FIG. 4, the outer space 51 is used as a storage space for the control board 125, and is also used as a connection space for connecting the transmission products.

In this embodiment, the electric power supplied from the power supply chamber 115 is supplied to the electric blower 117, the suction hose 200 and the extension pipe 40 via the control board 125.
0 to the suction body 500, so that the hose connection portion 104 connecting the suction hose 200 and the power supply chamber 1 are connected.
15 via the outer space 51. Similarly, the electric blower 117 is connected via the outer space 51 on the back side.

The release lever 160 provided in the power supply chamber 115 is transmitted to the outer space 51 via an opening 167 formed in the base case 118. The release lever 160 is provided to be rotatable in the horizontal direction via a rotation shaft.
When pressed by 59 and rotated via the rotation shaft, the vertical force is converted into a horizontal force, and the winding mechanism of the cord reel mechanism is operated to wind the power cord.

The pair of legs 118 are formed on both sides of the rear surface of the base case 118. One of the legs 118 is disposed above the plug storage portion of the cord reel device, so that the end of the plug can be hidden from the user, so that the design of the plug storage device can be improved. For example, it is possible to reduce the possibility that the ends of the plugs come into contact with the floor surface and the like when the storage position is reached, and the plug ends are damaged.

Next, the second power supply section 111 will be described with reference to FIG. This second power supply unit 111
The charging pack 168 includes a plurality of cells, and the power supply chamber cover 109a that holds the charging pack 168 from the bottom. Although various types of rechargeable batteries can be used as the rechargeable battery, in this embodiment, a rechargeable battery having 19.2 volts and a weight of 870 g by combining 16 cylindrical cells is employed. In this embodiment, two cylindrical cells are arranged in front and rear, with the longitudinal direction thereof coincident with the front-rear direction of the cleaner body 100, and the four cells are arranged in the left-right direction.
The charging pack 168 has a substantially rectangular parallelepiped shape with two rows and two vertical stages.

In this embodiment, the size of the code reel 163 is reduced (the diameter is 150 mm, the height is 150 mm) by making the power cord used for the code reel device 129 thin (0.75 mm 2). Is 45 mm).
The charging pack 168 is connected to the cord reel device 129.
Are set in the power supply room 115 for storing the large space without taking a large dead space.

The power supply room cover 109a comprises a charging terminal room 169 in which a charging terminal portion 132 is formed, and a charging room cover 170 which is openably and closably attached to the charging terminal room 169. Is located on the back side when attached to the cleaner body 100,
The pair of charging terminals 1 formed in a concave shape on the back side.
32 are formed.

On the other hand, when the charging terminal chamber 169 is attached to the power supply recess 115a, the charging chamber lid 170 can open and close the charging chamber 171 formed by the charging terminal chamber 169 and the power supply recess 115a. To cover. The user can open the charging chamber cover 170 fixed with screws or the like, and pull out the charging pack 168 connected to the charging terminal chamber 169 through the cord into the charging chamber 171 to perform maintenance.

The charging pack 168 of this embodiment
Sets the standard of the usable time to about 40 minutes. According to this, it is possible to clean about 160 tatami mats with one charge being 15 sec. Normally, one cleaning operation using the vacuum cleaner 1 takes about 5 to 8 minutes, so that sufficient power can be obtained in a normal cleaning operation.

As described above, in this embodiment, the first power supply section 110 and the second power supply section 111 constituting the power supply chamber 115 are replaced to provide a cordless vacuum cleaner and a home wiring. Since it is compatible with an electric vacuum cleaner, parts can be shared and cost can be reduced.

Further, the power supply chamber cover 109 constituting the first power supply section 110 and the power supply chamber cover 109a constituting the second power supply section 111 have the same basic shape. By arranging the plug lead-out portion and the charging terminal portion 132 at a portion corresponding to the rear portion of the vacuum cleaner main body 100, it is possible to cope with a general vacuum cleaner without increasing its usage.

Next, referring to FIGS. 7 to 11, the external structure of the cleaner body 100 according to this embodiment will be described in detail. FIG. 7 is an external perspective view of the cleaner body. FIG. 8 is an external view of the cleaner main body 100, and FIG.
(B) is a front view, (c) is a right side view, and (d) is a rear view. FIG. 9 is a bottom view. FIG. 10 is a right side view in a state where the main handle is raised, and FIG. 11 is a right side view in a state where a dust collection cover covering an upper part of the dust collection chamber is opened. Note that the cleaner main body 100 shown in FIGS. 7 to 11 has a first power supply unit 110 attached.

In FIGS. 7 and 8, as described above,
One of the features of this cleaner body 100 is that it has a substantially spherical basic form. The basic idea of this embodiment is that both sides of the sphere are the main wheels 101 whose center axis and the rotation axis are substantially coincident with each other, and the contact portion 101a formed on the outer periphery of the main wheel 101 is a floor surface. So that the cleaner main body 100 can be moved, and the bottom of a main body housing 116 that supports the main wheel 101 is cut inside the main wheel 101 so as to be movable. 10
3 is formed. Then, the auxiliary wheel 102 is disposed behind the flat portion 103 so that stable running is possible. As a result, stable running with three-point support is possible.

More specifically, the main body of the cleaner body 100 according to this embodiment has a basic shape of a sphere having a diameter W of 250 mm. The main wheel 101 having the center axis of the sphere substantially as the center of rotation is provided in the inner space on both sides of the sphere. here,
Since the wheel 101 is for driving the cleaner body 100, the installation surface 10 on the outer periphery of the main wheel 101 is used.
Since 1a is naturally installed on the floor, the size (diameter) of the main wheel 101 determines the size of the cut at the lower part of the sphere. In this embodiment, if the diameter of the main wheel 101 is increased, the wheel width W1 is reduced and the stability is lost, and the device arrangement space between the main wheels 101 is reduced. Focusing on the fact that when the diameter W is reduced, the size of the cut at the bottom of the sphere becomes larger and the internal volume of the cleaner body 100 becomes smaller, and the diameter h1 of the main wheel 101 is reduced to 160 m.
m. That is, in this embodiment, the diameter h1 of the main wheel has a size of about 65% with respect to the diameter W of the sphere, but the same effect is obtained at a ratio of 60% to 70%, for example, the diameter of the sphere. W is 25
In the case of 0 mm, the size of the main wheel h1 is changed from 150 mm to 1
If the size is 75 mm, the same operation and effect as those of this embodiment can be obtained.

In order for the main wheels 101 to be installed on the floor surface and to achieve good running, if the vehicle height is low, the threshold may hit the flat portion 103 and damage the threshold. Therefore, in this embodiment, the vehicle height h3 is set to 15 mm
Is set to According to this height, even if the main wheel 101 of the vehicle width W1 is inclined across the threshold, the flat portion 1
03 rarely hits the threshold. Furthermore, if the main wheel 101 is disposed at the center of both sides of the sphere and has the size of the vehicle height h3 and the diameter h2, the direction can be changed smoothly and the vehicle can be prevented from falling down. Further, it is possible to make it easy to get over a threshold or a cord.

In this embodiment, the wheel cover 133 constitutes the most protruding portion on both sides of the substantially spherical body. For this reason, it is conceivable that the overhanging portion is damaged by an obstacle. However, in this embodiment, since the wheel cover 133 forms a part of a sphere, the structure is such that strength can be obtained.

Further, in this embodiment, since the wheel cover 133 is formed of a transparent resin material, it is conceivable that the wheel cover 133 may be scratched by an obstacle. In particular, it is necessary to consider that the wheel cover 133 is transparent and scratches are conspicuous. Therefore, in this embodiment, a belt-like overhang 172 is formed in the horizontal direction near the center position of the wheel cover 133, and a grain pattern or the like is applied to the surface in advance.

Further, since the band-like overhanging portion may be slightly overhanging from the surface, it may be represented by a slightly raised character string instead of the belt-like overhanging portion. For example, by molding the product name in accordance with the overhang, it is possible to improve the merchantability and to take measures against abrasion and the like.

Also, as described above, in this embodiment, the three-point supporting leg 1
07 and 108 are provided. One of the leg portions 108 formed on both sides of the lower portion is arranged so as to make the plug hard to be seen from above, so that the design is enhanced while the lower portion is open. Easy.

Also, as shown in FIGS. 8D and 9,
In this embodiment, below the pair of legs 108,
A pair of auxiliary legs 108a is provided. This means that, when the traveling wheels are supported at three points as in the present embodiment, the rear auxiliary wheel 102 is used as a fulcrum and the storage posture of the vertical posture (see FIG. 31) is taken. Has an angled shape (planar shape is circular), so it may fall obliquely backward when the form changes, and fall down sideways without being able to take the three-point support posture by the legs 107 and 108. . These problems can be solved by providing the legs 108 at a lower position.
If 8 protrudes downward, it will be a hindrance when running or rotating.

In this embodiment, the position of the center of gravity is higher than the center position of the sphere because the electric blower 117 is disposed above, so that when the leg 108 is lowered, the load is increased. It is difficult to maintain a stable storage posture due to too much engagement with the leg 107 side.

Therefore, in the present embodiment, a pair of auxiliary legs 108a having a smaller overhang than the pair of legs 108 is provided below the pair of legs 108, so that when the posture is changed to the vertical posture, the auxiliary legs 108a are formed. It serves as a guide to prevent the auxiliary leg 108a from falling obliquely backward, and serves to improve the change to the storage position.

Further, in this embodiment, the hose mounting portion 104 is provided at the front portion of the cleaner body 100 so as to protrude from the sphere, so that the dust collecting chamber 113 and the blowing chamber 11 are provided.
4 and a power supply chamber 115 (refer to FIG. 3), while maintaining a substantially spherical shape in which the suction hose 200 is pulled to keep running.

That is, in order to cope with the pulling travel by the suction hose 200, the hose mounting portion 104 needs to have a mounting portion having a length to some extent. If the hose mounting portion 104 having this length is to be substantially included in a sphere, a dead space increases around the hose mounting portion 104, and the entire sphere needs to be enlarged. Also, the impression of the sphere may be destroyed. Therefore, in this embodiment, by providing the hose mounting portion 104 so as to protrude from the sphere, a compact vacuum cleaner main body 100 having good internal mounting efficiency is realized.

The lock switch 148, the dust collection chamber cover 120, the opening / closing handle, and the auxiliary handle 106
In addition to providing good strength, the shape of the substantially spherical body is given a one-point accent to improve the design.

As described above, the cleaner main body 100 according to the present embodiment has a structure in which impacts are dispersed and are not easily deformed since the cleaner has a basic shape of a substantially spherical body having excellent strength.
In addition, by adopting the spherical structure excellent in strength, the thickness of the resin can be reduced or the number of internal reinforcing ribs can be reduced, so that the weight can be reduced. Furthermore, the sound generated from the inside is less likely to reverberate by adopting the substantially spherical basic form, and the hermetically sealed structure including the double structure has a small sound leakage and can greatly contribute to noise reduction. .

In FIG. 10, in this embodiment, the rotary shaft 143 of the main handle portion 105 is provided substantially above the center position of the spherical body, and as shown in FIG. 147 is provided at a position lower than the rotation shaft 143 and at the rear. Thus, the cleaner main body 100 can be lifted in a well-balanced manner with a large handle. Further, the dust collection chamber cover 120 is opened to expose the dust collection chamber 113 to a large extent. Replacement can be facilitated.

In this embodiment, the main handle 1
05 is pulled up from the rear, and the dust collection chamber cover 120 is pulled up from the front. In this case, the main handle 105 must be provided in the vicinity of the center of the sphere, and the opening and closing angle of the dust collection chamber cover 120 must be increased so as to obtain as large an opening as possible. The problem here is that the upper surface of the spherical center position is spherical.

For example, if the rotation shafts 143 and 147 of the main handle portion 105 and the dust collection chamber cover 120 are the same rotation shaft, the shape of the sphere must be broken. Therefore, it is necessary to make one rotation axis lower than the other rotation axis in accordance with the spherical surface. Further, when the rotation shaft 147 of the dust collection chamber cover 120 is to be provided inside the main handle section 105, the main handle section 10 of the dust collection chamber cover 120 is not provided.
5, a large opening / closing angle cannot be obtained. Further, the main handle portion 105 becomes too large.

Therefore, in this embodiment, the two rotating shafts 143 and 147 are provided with a height difference and a front-back difference as described above, that is, the positions of the rotating shafts of the two rotating shafts 143 and 147 are set in the vertical direction. The rotary shaft 147 of the dust collecting chamber cover 120 is provided to be shifted rearward from the rotary shaft 143 in order to obtain a large opening. Thereby, the usability of the main handle portion 105 and the dust collection chamber cover 120 arranged near the top of the sphere can be improved.

Next, FIGS. 3 to 5 and FIGS. 12 to 16
The flow of air in the cleaner body 100 according to this embodiment will be described with reference to FIG. 12 is an exploded perspective view showing a state in which the ventilation cover 136 is removed, FIG. 13 is an enlarged view of the exhaust port 166, FIG. 14 is a perspective view showing a reversing path of the air passing through the cleaning filter, and FIG. FIG. 16 is a partially enlarged view showing a nearby exhaust passage, and FIG.

First, referring to FIG.
The air containing dust sucked through the suction hose 200 connected to the dust collecting chamber 113 enters the dust collecting chamber 113 from the hose connection portion 104, and the air in the disposable dust collecting bag 152 attached to the dust collecting chamber 113 It is taken in. The air from which dust has been removed by the disposable dust bag 152 is taken into the electric blower 117 provided in the blower chamber 114 through the ventilation slit 154 provided in the partition wall 121 and the primary filter. The air taken into the electric blower 117 cools its own drive motor 156 and then reaches the air passage space 158.

4 and 5, the air discharged to the air passage space 158 is sent to the filter storage chamber 127 through the communication path 164, and the air is discharged from the clean filter 112 in the filter storage chamber 127. By passing through, fine dust can be removed and exhaust with high cleanliness can be performed.

Here, the cleaning filter 112 used in this embodiment is a three-stage filter including antibacterial and deodorant. In other words, an HEPA clean filter is used in which an ultra-fine charged layer (for example, a non-woven fabric of non-woven fabric) that can be used to remove fine dust such as mites, pollen, mold spores, and mite dust is sandwiched between an antibacterial deodorant fiber layer and a special reinforcing layer. Has adopted. Since the clean filter 112 employs a filter used in an air purifier or the like, by passing the clean filter 112 therethrough, indoor air can also be cleaned. For example, according to the cleaning filter 112 of this embodiment, it is possible to remove fine dust of 0.3 μm or more by 99.9% and discharge clean air.

In this embodiment, the stacked cleaning filters 112 are folded to form a substantially rectangular parallelepiped shape. If this is provided in the circular main wheel 101, it is possible to obtain the largest clean area if it is formed in a circular shape. However, in this case, the yield associated with the manufacture of the cleaning filter 112 is reduced, and the cost is increased. Therefore, in this embodiment, the yield can be improved by forming a substantially rectangular parallelepiped.

In this embodiment, the air that has passed through the cleaning filter 112 is inverted and taken into the outer space 51 again, so that the exhaust passage is lengthened to reduce noise. This will be described with reference to FIGS.

12 to 15, in this embodiment, the air that has passed through the cleaning filter 112 passes through the central opening 137 provided at the center of the ventilation cover 132, and the air in the wheel cover 133 is removed. Cover space 1
The air is discharged into the wheel cover space 133a, and is reversed to reach the outer space 51 via the outer opening 138 of the ventilation cover 132 and the ventilation path 135. Then, after cooling the control board 125 provided in the outer space 51, from the space between the main wheel 101 and the main body casing 116 through the exhaust port 166 formed around the wheel base 126. Exhausted.

Referring to FIG. 12, in this embodiment, the communication passage 164 is arranged to be offset with respect to the filter storage chamber 127. However, as shown in FIG. Since the space is provided in front of the air, the air entering from the communication path 164 is cleaned using the entire cleaning filter 112. Further, the outer opening 138 has an L-shaped cross section, and the outer wheel opening 138 is connected to the communication passage 1 from the transparent wheel cover 133.
The inside of 64 is hidden. At this time, since the air to be exhausted is refracted and exhausted a plurality of times, each refracted portion is formed in an R shape for noise reduction.

Further, in FIGS. 12 and 13, in this embodiment, since the clean air is discharged from the space (gap) between the main wheel 101 and the main body casing 16, the outer space 51 is discharged from this gap. There is a possibility that the inside can be seen or a foreign substance is mixed in from the gap. Therefore, in this embodiment, in order to solve the above problem,
An exhaust port 166 formed around the 126 wheel base
The slit shape is devised.

That is, the exhaust port 166 is formed with a plurality of ring-shaped openings around the wheel base 126 so that the openings become narrower toward the outer periphery.
Thus, the wheel base 126 which is hard to be seen from the outside
By evacuating more from the side and making the outer periphery thinner, it is harder to see from the outside and foreign matter is less likely to enter.
Furthermore, around the wheel base 126, the main wheels 101
Since it is also a part that needs strength to support the exhaust port, by forming the exhaust port 166 as an opening divided in the circumferential direction,
In addition to solving this problem, the effect of making it difficult for the foreign matter to enter is further enhanced.

According to this embodiment, as shown in FIG. 16, since the air is discharged from the periphery of the main wheel 101, for example, the user holding the main handle portion 105 is directly operated by the wheel. Compared with a structure in which the air is exhausted, since the exhaust is not directly applied, it is possible to reduce the discomfort to the user. Further, since the air to be exhausted is exhausted through a long exhaust passage as compared with the air exhausted directly from the main wheel 101, noise can be reduced. In particular, as in this embodiment, the blower chamber 115 and the main wheels 1
In the case where 01 is arranged at the shortest distance, if an exhaust port is provided in the wheel cover 133, noise in the ventilation chamber 115 is exhausted through the shortest distance opening, which may cause discomfort to the user. Becomes However, in this embodiment,
By closing the wheel cover at the shortest distance, noise can be reduced. In addition, the exhaust passage can be made longer accordingly. Noise can be further reduced.

Further, since the exhaust port 166 is located behind the upper half portion of the main wheel 101, the exhaust flow toward the floor surface is reduced, and the dust on the floor surface is not sowed up.

By being twisted about the tube axis of 00, the mouthpiece body 501 can be rotated with respect to the floor surface.

Next, FIGS. 18 and 19 and FIGS. 23 and 2
4, the specific structure and operation of the rotating brush 504 will be described. First, as shown in FIG. 23, the rotating brush 504 includes four blades 522 projecting in a cross shape outward at an equal interval with respect to the rotating shaft. This feather 5
Reference numeral 22 indicates that the left and right rotating brushes 504 are attached with a shift of 45 degrees. For this reason, as shown in FIG. 24, when the wing 522a of the rotating brush 504a lifts the floor surface to one side, the wing 522b of the other rotating brush 504b does not contact the floor surface. When the rotating brush 504 rotates, the states of the left and right rotating brushes 504 are reversed. This allows
In this embodiment, the left and right rotating brushes 504 alternately lift the floor to perform cleaning.

Further, as shown in FIG.
Are formed so as to protrude on both sides. For this reason, the front portions on both sides of the rotating brush 504 are connected to the bearing portions 510.
, And the rear portion protrudes to both sides from the bearing portion 510 and rotates. On the other hand, the central portion of the rotary brush 504 is arranged such that the front portion of the connecting gear 511
The tips of 22 overlap and rotate.

The wing 522 shown in FIG. 17 to FIG.
Although it is formed of a plate-shaped flexible spatula, a brush having a long bristle has the same effect as long as the brush has a similar shape. As shown in FIGS. 18 and 19, a pair of rotating brushes 5 are provided.
The wings 522 may be formed by twisting along the longitudinal direction as long as the wings 522 of 04 overlap each other at the center.

According to the mouthpiece 500 of this embodiment having such a structure, as shown in FIGS. 18 and 19, the drive motor 505 provided at the center of the mouthpiece body 501 is provided.
Is transmitted to the rotating brushes 504 on both sides to rotate, so that the raised dust can be sucked while the floor surface is lifted, thereby improving the cleaning efficiency.

In this case, as in the conventional example, the one employing one rotating brush has a driving belt provided on one side for rotating the rotating brush. There is a problem that the cleaning performance of the device decreases.
However, according to this embodiment, since the drive mechanism for the rotating brush is not provided on one side, the above-mentioned problem can be reduced.

In this embodiment, the suction main body 5
When both side portions of the suction port 01 are located at corner portions of the wall surface, or when one side of the suction main body 501 is moved along the wall surface, the edge portion of the wing 522 protruding from the bearing portion 510 causes the edge portion of the wall to close. Since the cleaning can be performed, the above problem can be further reduced.

On the other hand, in this embodiment, since the drive mechanism is provided at the central portion of the pair of rotary brushes 504, there is a concern that there is a problem in the cleanability of the central portion. However, in this embodiment, since the free connecting portion 502 is provided in the central portion, the suction force of this portion is higher than the suction force of both sides, so that the portion with poor performance in lifting can be solved. Moreover, the lifting of the central part is performed by the suction body 5
By simply changing the movement of 00, the rotary brush 504 can be used to raise it. However, considering that the cleaning of the wall is physically difficult, the structure is excellent in cleaning the wall.

Further, in this embodiment, the gap between the pair of rotary brushes 504 can be reduced by arranging the pair of rotary brushes 504 in a V-shape.
Further, in this embodiment, the above problem can be further reduced by making the tips of the blades 522 of the rotating brushes 504 on both sides overlap.

In this embodiment, openings 523 are formed at both ends of the lower case 506 shown in FIG. 17 to form clearance holes at the front ends of the blades 522 at both rear portions of the rotating brush 504. ing. Therefore, this opening 5
Since the tips of the wings 522 protrude from 23, the cleanliness of the wall can be further improved.

In the embodiment shown in FIGS. 18 and 19, the drive motor 505 is provided so that the rotation axis coincides with the depth direction of the mouthpiece 500, so that the balance in the left-right direction can be improved. In this embodiment, a connecting gear 511 having uneven teeth formed on the circumferential side of the disk is used, and the rotating shafts of the pair of rotating brushes 504 whose bending axes are bent are connected by a flexible rotating connecting member. The pair of rotating brushes 504 arranged in a V-shape can be rotated by the driving force of the driving motor 505.

The same operation and effect are not limited to this structure. For example, FIG. 20 shows a case where the rotating shaft of the drive motor 505 is arranged along the longitudinal direction of the suction main body 501. This can be achieved by employing a triangular gear 524. Further, as shown in FIG. 21, the connection gear 511 and the drive motor 505 may be arranged obliquely. In the embodiments of FIGS. 20 and 21, the drive motor 505 can be shifted to one side from the center position of the mouthpiece 500, so that the control board and the like can be arranged in the space created by this eccentric arrangement. .

The embodiment shown in FIG. 22 shows a structure in which the drive belt 525 is employed without using the connecting gear 511. Thus, the pair of rotating brushes 504
Are arranged in a V-shape, and the drive motor 505 disposed at the center thereof is connected by various connection structures, so that the restriction due to the arrangement of the drive motor 505 can be relaxed. Suction body 501 in which is disposed
The drive motor 505 and various control boards can be centrally arranged at the rear center of the vehicle. This makes it possible to reduce the size of the suction port body 501 other than the central portion, and to improve the cleanability of a narrow gap or a wall.

Next, the external structure of the mouthpiece 500 will be described with reference to FIGS. In FIG. 25, the rotating brush 504 is disposed in a suction body dust collecting chamber 521 above the dust collecting port 503 (see FIG. 27) opened in a V-shape on the bottom surface of the lower case 506, and its wings are arranged. The blade 522 is arranged to be exposed from the dust collection port 503. A first rotating shaft portion 516 for connecting the free connecting portion 502 is formed from an upper center to a rear portion of the suction body dust collecting chamber 521, and the rotating brush 504 sucks up dust and air together. It can be conveyed to the free connecting portion 502.

The drive motor 505 is disposed behind the suction body dust collection chamber 521, and the free connecting portion 502 rotates at a position above the drive motor 505 and the suction body dust collection chamber 521. Can work as possible.

Referring to FIGS. 26 and 27,
1 has a structure in which the front side is formed linearly, the length in the depth direction becomes narrower toward both sides, and the free connecting portion 502 is attached to the rear of the central portion. Since the drive motor 505, the control board, and the like are centrally arranged in the central rear portion of the suction main body 501 to which the free connecting portion 502 is attached, the suction main body 501 can be made flat and small. , To improve the cleanability of narrow gaps.

Further, as shown in FIG.
03 are formed close to the end of the mouthpiece body 501, so that the cleaning property at the wall side can be improved.

Next, the extension pipe 400 will be described in detail with reference to FIGS. FIG. 28 is an exploded view of parts of the extension pipe 400, FIG. 29 is an explanatory view of the expansion and contraction operation of the extension pipe 400, and FIGS.

First, the structure of the extension pipe 400 according to this embodiment will be described with reference to FIG. The extension pipe 40

The first tube 401 is a cylindrical straight tube, and the second tube 402 can be accommodated in the entire length of the tube. For this reason, as shown in FIG. 29A, in a state where the second pipe 402 is pulled out to the maximum, the two pipes 402 are stretched to the maximum except for the part where the two pipes 402 are wrapped and connected in terms of strength. Conversely, as shown in FIG. 29 (c), in a state where the second tube 402 is retracted and contracted to the minimum, the upper end of the second tube 402 is connected to the first tube. 4
01 can be stored near the upper end of the
Since the longest dimension and the minimum dimension associated with the expansion and contraction of 0 can be increased, the storability can be improved while improving the usability of a tall user.

Further, in this embodiment, the hand handle 300 is disposed near the upper end of the first tube 401 in the longitudinal direction. For this reason, compared with the conventional example in which the handle is attached to the upper end of the extension tube, the length of the handle can be set to the range of expansion and contraction of the extension tube 400. The difference between the longest dimension and the minimum dimension due to expansion and contraction of the tube 400 can be increased.

The handle portion 300 is formed so as to branch off to the upper end of the first tube 401 to form the holding portion 301. And this holding part 3

The release button 303 is provided at a position where the user can operate with one finger while holding the holding part 303 with one hand, and an operation of pulling the release button 303 with one finger (moves upward in the drawing) Operation), the locked state of the lock mechanism 408 is released. That is, in this embodiment, the connecting rod 411 passing through the connecting rod passage 405 and the connecting rod 41
The release button 303 and the sliding member 410 are connected to each other via a direction changing mechanism 412 that changes the moving direction of the moving member 1. When the user operates the release button 303 so as to be attracted (pulled upward in the drawing), the connecting rod 411 is pulled upward (upward) in the direction of the arrow. This pulling force is reversed by the direction change conversion mechanism 412 and operates in a direction to push the sliding member 410 downward. The sliding member 410 is in a normal state,
The stopper pin 409 is held at an upper position by a spring (not shown) and protrudes inward. The locking state of the second pipe 402 is released by the projecting stop pin 409 entering the concave portion of the sliding member 410 as the sliding member 410 moves.

As described above, in this embodiment, for example, the user holding the holding portion 302 in the standing posture only operates the release switch 303, and this extension tube 40
The length of 0 can be adjusted.

Next, as shown in FIG. 37, the extension tube 400 can rotate left and right by forming one end of a lower arm 514a and an upper arm 515a so as to form a second rotating part 517a. When the other end of the lower arm 514a is provided with a rotation axis orthogonal to the rotation axis of the second rotation part 517a, and combined with the suction body 500a that rotates the suction main body 501a in the vertical direction with respect to the floor surface, The extension pipe 400
The leg portion 404 is caused in conjunction with the contracting operation of the mouthpiece, and further, the rotation of the second rotating portion of the mouthpiece 400 is locked so that the contracted extension tube 400 can be held in a vertical posture. . This structure can be provided with the same structure in the mouthpiece 500 described with reference to FIG. 17, but for convenience of explanation, the mouthpiece 500a will be described. The mouthpiece 500a shown in FIG. 28 is different from the mouthpiece 50 shown in FIG.
0a shows an exploded view.

The leg 404 has one longitudinal end rotatably attached to the end of the first tube 401, and the longitudinal direction of the leg 404 is connected to the first tube 401 via a spring 413. The other end is arranged to extend toward the second tube 402 side along the longitudinal direction of the body 401.

On the other hand, the mouthpiece 500a is attached to the other end of the second pipe 402. This mouthpiece 500
The upper arm 515a has a tubular shape, one end of which is attached to the end of the second tubular body 402, and the other end of which is L
The second rotating part 517a is bent in a shape. Also,
A communication pin 550 is provided on a side surface (front side) of the upper arm portion 515a.
Are slidably mounted along the longitudinal direction of the upper arm 515a, and the outside thereof is covered with a pin cover 551. And the communication pin 550 is always
The upper end protrudes toward the second tube body 402 and is arranged.

The lower arm 514a has the tubular shape and has one end rotatably attached to the mouthpiece body 501a and the other end bent into an L-shape.

Now, a method of operating the extension pipe 400 having such a structure and the mouthpiece 500a will be described with reference to FIG.

First, in FIG. 29 (a), in this embodiment, when the user holds the holding portion with one hand and operates the release lever 303 in the direction of pulling with the index finger (the direction of the arrow), the connection is established. The rod 411 operates as shown by the arrow and is pulled upward. As shown in FIG. 28, the pulled connecting rod 411 is inverted by the direction changing mechanism 412 and operates in a direction to push the sliding member 410 downward, so that the lock mechanism 408 is locked. Is removed, the extension tube 400 can be expanded and contracted. If the handle 300 is moved downward in this state, the extension tube 400 can be contracted by gravity or the like. Then, if the release switch 303 is returned to its original position with an appropriate length, the lock mechanism 408 is again returned.
Can be locked.

In this state, when the handle portion 300 is pushed downward, the leg portion 40 which has been housed along the longitudinal direction of the extension tube 400 is obtained.
When the front end of the upper part 4 rides on the upper end part of the upper arm part 515a of the suction body 500a and further pushes down the hand handle part 300, the lower end part gradually turns outward along the inclined surface inside the leg part 404. (See FIG. 2B). Then, the lower end of the first tube 401 hits the upper end of the communication pin 550 provided on the upper arm 515a and pushes it down. The lower end of the communication pin 550 that has been pushed down is fixed to a fixed lock hole 554 provided at the upper end of the decorative cover 553 of the lower arm 514a.
Fits. Accordingly, the rotation of the mouthpiece 500a in the left-right direction is locked, and the mouthpiece body 501 is locked.
a and the extension tube 400 are fixed, and the leg portion 404 opened outward is also fixed.

As a result, the extension pipe 4 in the vertical state
Since 00 is held as a three-point support by the suction body 501a and the leg 404, the vacuum cleaner 1 can be installed in a state as shown in FIG.

Returning to FIG. 28, an L-shaped bent tube 201 is provided at the end of the suction hose 200 attached to the extension tube rotating part 403 formed at one end of the first tube 401. The end of the bent tube 201 is
Together with one end of the tube 401, the extension tube rotating part 403 in which the bent tube 201 rotates on the same rotation axis as the tube axis of the first tube 401 is formed.

Furthermore, a hose member is rotatably attached to the other end of the bent tube 201. That is, the first
The hose member is attached to the pipe body 401 by two rotating mechanisms, so that the user can
Even if various movement operations to the mouthpiece 500 are performed while holding the value of 0, the suction hose 200 can be operated without being twisted and without imposing a large burden on the user.

According to such an extension tube 400, it can be extended to an appropriate length at the time of use, and at the time of storage, can be stored in a size that can be stored in a closet. FIG. 30 to FIG. 33 show dimensional relationships and installation or storage postures in various states.

First, FIG. 30 shows a dimensional relationship assuming a case in which a standard Japanese house is stored at the height of a closet. As described above, the cleaner main body 50 of this embodiment
0 indicates that the container can be stored in the vertical position, and FIG. 30 shows a case where the container is stored in the closet in this storage position.

The height H1 of the lower storage section of the closet of a standard Japanese house is about 700 mm. The height H2 when the extension pipe 400 and the mouthpiece 500 are assembled at this height H1 and stored in a vertical position must be 695 mm or less. When the height is set at the height H2, the suction hose 200 is used.
Bend the hose when attaching
Considering the height of the pipe, the height H up to the longest part of the extension pipe 400
3 must be less than about 665 mm. Further, since the height H6 of the mouthpiece 500 needs to be 140 mm, the length H5 of the extension tube 400 is 525 mm. Since the length H7 of the overlapping portion between the first pipe 401 and the second pipe 402 needs to be about 40 mm, the extendable stroke H4 of the extension pipe 400 in this embodiment is set to about 48.
It is set to 5 mm.

On the other hand, as shown in FIG. 31, according to the extension pipe 400 adopting the above-mentioned dimension system, when the extension pipe 400 is set up, the longest length of the extension pipe 400 is equal to the length of the suction hose 200. Of the extension pipe 400 can be set to 1150 mm. If it can be extended to such a length, the length of the extension pipe of a general vacuum cleaner can be secured.

The length of the extension pipe 400 is somewhat affected by the height H6 of the suction body 500 and the height of the suction hose 200.
A similar effect can be obtained if the length H5 is within the range of 495 mm to 550 mm.

Further, the extension pipe 400 according to this embodiment
According to FIG. 30, the extension pipe 400 can be installed independently as shown in FIG.
Since it is not necessary to set and store at 0, the trouble of setting can be saved, and the responsiveness at the time of use is improved. Furthermore, as shown in FIG. 33, when cleaning is temporarily stopped, the extension pipe 400 can be held in an upright posture, so that the extension pipe 400 is bent over the floor as in the conventional example, and Since the work can be performed in a standing posture without performing a crouching operation, usability can be improved.

Next, the charging stand 600 will be described with reference to FIGS. In this embodiment, when the second power supply unit 111 is attached to the cleaner main body 100, the charging can be automatically performed at the time of storage by using the charging stand 600 shown in FIG.

In FIGS. 34 and 35, the charging stand 60
Reference numeral 0 denotes a flat and deep main body shape having a substantially rectangular upper surface. The charging stand 600 includes a plate-shaped lower case 601 and an upper case 602 that covers an upper portion of the lower case 601. The charging stand 600 is provided with a raised portion 603 at the rear, a cleaner main body receiving portion 604 formed with an arc-shaped wall at the front, and further provided at the forefront with the cleaner main body receiving portion 604. A mouthpiece receiving portion 605 formed by standing up one step is formed. The raised portion 603
Is provided with a charging device (not shown) therein, and ventilation holes 606 are respectively formed in lower portions on both sides of the raised portion 503 and the arc-shaped wall surface in order to cool internal heat by natural convection. . A charging lamp 607 is provided on the upper surface of the protruding portion 603.

The vacuum cleaner main body receiving portion 604 is provided at its front side with a convex charging terminal 608 that fits into the concave charging terminal portion 132 provided on the vacuum cleaner main body 100. A positioning guide 609 for holding the leg portion 107 is provided from the rear side to the arc-shaped wall surface.

[0168] In the charging stand 600 of this embodiment, the standard charging time is set to 4 hours. For this reason, if the cleaning work is performed before the charging, the charging can be completed by the evening. If the user wants to use it suddenly, it can be used for 10 minutes when charging for 1 hour and 5 minutes when charging for 30 minutes.

The charging lamp 607 is turned on during charging, and the lamp is turned off when charging is completed, thereby preventing the battery from being damaged due to excessive charging.

In FIG. 36, in this embodiment, the legs 307 and 308 are set in a vertical position such that the upper surface of the cleaner main body 100 is located on the ridge 603 side so that the legs 307 and 308 are installed on the charging stand 600. Set by

In this embodiment, the mouthpiece receiving portion 60
5 is formed to be smaller than the depth dimension of the suction body 500 in which it is installed. That is, in the mouthpiece 500, the angle of the free connecting portion 502 in the height direction with respect to the mouthpiece body 501 is set to 90 degrees.
When the 02 is rotated, there is no room for the rotation operation of the universal connecting portion 502, and it becomes difficult to set the charging unit 600 on the charging stand 600. In addition, some of the recent flexible connecting portions 502 cannot have an angle of 90 degrees in the vertical direction. For this reason, the depth dimension of the mouthpiece receiving portion 605 is set such that the height of the free connecting portion 502 can be set to the charging stand 600 with a sufficient angle with respect to the mouthpiece 500. It is smaller than the depth dimension of the mouthpiece 500.

More specifically, the size of the mouthpiece receiving portion 605 is set so as to place the vertically installed extension pipe 400 within its projected area. As a result, FIG.
(A) As shown in the drawing, the mouthpiece 500 is located just below the extension pipe 400 and the mouthpiece receiving portion 6 of the charging stand 600.
05, and the mouthpiece receiving portion 605 has a thickness in the height direction, so that the tip of the mouthpiece 500 is lowered forward and installed on the charging stand 600. As a result, there is play in the operation range of the suction main body 501,
01 is easier to install on this charging stand 600 than disposing it on a horizontal installation surface. In addition, the suction main body 50
(1) As shown in FIG. 3 (b), the charging stand 600 is set on a carpet floor as shown in FIG.
Even when the charging stand 600 is buried on the carpet floor, the height (thickness) of the mouthpiece receiving portion 605 allows the buried portion to be absorbed by the play. The handleability at the time of installation can be improved.
In addition, the installation area of the charging stand 600 can be minimized.

Next, FIG. 37 shows the main body 100 of the cleaner.
