Description

electric vacuum cleaner

technical field

The present invention relates to an electric vacuum cleaner.

Background technique

Conventionally, in the electric vacuum cleaner, there have been problems such as weight reduction and easy portability for the user. Therefore, various electric vacuum cleaners have been developed.

Furthermore, in recent years, stick vacuum cleaners have been commercialized. Various techniques are also disclosed about stick vacuum cleaners (for example, refer patent document 1).

Patent Document 1 discloses a stick-type vacuum cleaner in which an extension pipe is connected to a dust box and a handle is connected to the dust box.

However, in the structure of the vacuum cleaner described in Patent Document 1, the space between the handle and the dust box is narrow. Therefore, in the case of a user with large hands, it is difficult to hold the vacuum cleaner. In addition, the dust box is connected vertically with respect to the extension pipe. Therefore, the user cannot easily see the internal state of the dust box (for example, the accumulation state of garbage, etc.) during the cleaning process.

Detailed ways

Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, this invention is not limited to this embodiment.

(Embodiment 1)

Hereinafter, the vacuum cleaner according to Embodiment 1 of the present invention will be described with reference to FIG. 1 .

FIG. 1 is a side view of the vacuum cleaner according to Embodiment 1. FIG.

As shown in FIG. 1 , the vacuum cleaner 1 includes a main body portion 2 , a connection pipe portion 3 connected to the main body portion 2 , an extension pipe 4 connected to the connection pipe portion 3 , a suction nozzle 5 connected to the extension pipe 4 , and the like.

The suction nozzle 5 is configured to be detachable from the extension pipe 4 . Moreover, the extension pipe 4 is also comprised so that attachment or detachment with respect to the connection pipe part 3 is possible. Furthermore, the extension pipe 4 may have a structure capable of expanding and contracting.

In the following, for example, in the vacuum cleaner 1 shown in FIG. 1 , the suction nozzle 5 side is the front, the main body 2 side is the rear, the upper arm 6 side is the upper side, and the lower arm 7 side is the lower side. illustrate.

The main body portion 2 includes an upper arm portion 6 , a lower arm portion 7 , an intermediate portion 8 , a handle portion 9 , and the like.

The handle part 9 is formed in the rear side of the main body part 2, and is arrange|positioned so that the upper arm part 6 and the lower arm part 7 may be connected. The handle portion 9 constitutes a portion that the user holds when using the vacuum cleaner 1 .

The intermediate portion 8 is disposed between the upper arm portion 6 and the lower arm portion 7 on the front side of the main body portion 2 , and incorporates a later-described electric fan 10 (see FIG. 2 ) and the like.

The main body portion 2 is formed by combining the above-described components such as the upper arm portion 6 , the lower arm portion 7 , the intermediate portion 8 , and the handle portion 9 .

In consideration of strength and heat resistance, the body of the main body portion 2 is formed of, for example, a thermoplastic resin such as polypropylene (PP) or a material obtained by mixing polypropylene with fibers or the like. In addition, as a material of a body, polypropylene etc. are suitable, but other materials, such as ABS resin, can also be used, for example.

In addition, the main body part 2, the connection pipe part 3, etc. of Embodiment 1 are mainly formed using the material like polypropylene. However, for example, another material such as ABS resin may be used for a part of the parts and a portion where strength is required.

A connecting pipe portion 3 is arranged in front of the main body portion 2 . A dust box 11 is detachably connected to the connection pipe portion 3 on the upper side. An extension pipe 4 is detachably connected to the connection pipe portion 3 on the front side.

A suction nozzle 5 is detachably connected to the extension tube 4 on the front side. The suction nozzle 5 is connected so as to be rotatable within a predetermined angular range with the fulcrum A of the suction nozzle 5 being the direction of the arrow B or the direction of the arrow C in the axial direction.

In addition, the main body of the vacuum cleaner is constituted by the main body portion 2, the dust box 11, and the like.

Moreover, the vacuum cleaner main body can be moved by a user holding the handle part 9 and operating.

The dust box 11 is attached to the upper side of the connection pipe part 3 of the main body part 2 of the vacuum cleaner main body shown in FIG. 1 . Thereby, the user can easily confirm the state of the amount of garbage in the dust box 11 and the like even in a state of holding the handle portion 9 . In this case, it is particularly preferable to constitute the container of the dust box 11 with a transparent material. Thereby, the user can easily confirm the amount of garbage in the dust box 11 . Moreover, as a transparent material, PMMA (polymethyl methacrylate resin), PET (polyethylene terephthalate), etc. are illustrated, for example.

The schematic structure of the vacuum cleaner 1 of Embodiment 1 is comprised as mentioned above.

Next, the structure of the vacuum cleaner main body of the vacuum cleaner 1 will be described with reference to FIG. 2 .

2 : is a figure which shows the schematic structure of the partial cross section of the vacuum cleaner main body of the vacuum cleaner 1 shown in FIG. Specifically, FIG. 2 is a diagram showing an outline of a cross section around the main body portion 2 and the connecting pipe portion 3 in the side view of FIG. 1 . In addition, in FIG. 2, illustration and description are abbreviate|omitted about the structure which is not directly related to this invention.

As shown in FIG. 2 , an electric fan 10 is built in the intermediate portion 8 of the main body portion 2 . A cylindrical dust box 11 is attached to the front of the electric fan 10, for example. At this time, the electric fan 10 and the dust box 11 are arranged so that the rotation axis of the electric fan 10 and the central axis of the dust box 11 are on the same axis D shown in FIG. 2 .

In addition, the space inside the connection pipe portion 3 and the space inside the dust box 11 communicate with each other through the opening. That is, the opening is formed by connecting the first opening 12 formed in the connection pipe portion 3 and the second opening 13 formed in the dust box 11 .

Furthermore, the space inside the dust box 11 and the space inside the electric fan 10 communicate with each other through the opening. That is, the opening is formed by connecting the third opening 14 formed in the dust box 11 and the fourth opening 15 formed in the main body portion 2 .

In the above-described connected state, when the electric blower 10 is driven, suction wind is generated. Dust, garbage, etc. (hereinafter abbreviated as "dust") sucked from the suction nozzle 5 is sucked by the suction wind through the extension pipe 4 , the inside of the connecting pipe part 3 , the first opening 12 and the second opening 13 . Dust box 11. Then, in the dust box 11, the dust is centrifuged from the suction air containing the suctioned dust. After that, the suction air from which the dust has been separated is sucked into the electric fan 10 through the third opening 14 and the fourth opening 15 . The sucked suction air is discharged to the outside from the exhaust port 16 (see FIGS. 9 and 10 ) of the main body 2 .

In addition, the exhaust port 16 is formed in the surface of the part surrounding the circumference|surroundings of the electric fan 10 of the main-body part 2 in FIG. 2, and this is not shown in FIG.

At this time, in the vacuum cleaner 1 of Embodiment 1, for example, the height dimension E of the upper arm portion 6 is formed to be approximately 30 mm, and the height dimension F of the lower arm portion 7 is formed to be approximately 70 mm. The lower arm portion 7 incorporates, for example, a secondary battery 17 such as a lithium ion battery. Therefore, the thickness (height in the up-down direction) of the lower arm portion 7 is set to a thickness required for the built-in secondary battery 17 . That is, the lower arm portion 7 is formed with a larger height dimension (thickness) than the upper arm portion 6 . Thereby, the secondary battery 17, such as the above-mentioned lithium ion battery, is arrange|positioned below the electric blower 10 which has a weight. As a result, since the electric fan 10 and the secondary battery 17 can be balanced, the user can hold the handle portion 9 stably.

The secondary battery 17 is arranged in the area in the lower arm part 7 from the position of the approximate center (including the center) of the electric fan 10 to the rear end of the handle part 9 in the front-rear direction of the vacuum cleaner 1 .

In addition, the secondary battery 17 is arranged so as to extend toward the rear and lower side so as to be inclined with respect to the connecting pipe portion 3 . Specifically, the axis G of the secondary battery 17 is inclined at an angle I (for example, about 10 degrees) with respect to the axis H corresponding to the pipe axis direction of the connection pipe portion 3 . In addition, the angle I does not necessarily have to be 10 degrees, and may be other angles. However, the angle I is preferably an angle in the range of approximately 7 degrees to 13 degrees.

The handle portion 9 is formed to be inclined toward the rear and lower side from the upper arm portion 6 toward the lower arm portion 7 on the rear side of the main body portion 2 . Thereby, as described above, even if the electric fan 10 is arranged above the axis H which is the pipe axis connecting the pipe part 3 , the user can hold the handle part 9 and clean stably.

In addition, as shown in FIG. 2 , the handle portion 9 is configured such that the center of gravity GG exists in the vertical direction of the electric fan 10 on the axis D corresponding to the rotation axis of the electric fan 10 and the axis H corresponding to the pipe axis of the connection pipe portion 3 . between. In this case, it is more preferable that the center of gravity GG of the handle portion 9 exists at a position closer to the axis D of the electric fan 10 than the axis H of the connection pipe portion 3 . Thereby, even if the electric blower 10 is arrange|positioned at the upper position than the axis line H of the connection pipe part 3, a user can hold the handle part 9 and clean stably.

That is, when the shape of the handle portion 9 is different from that of the first embodiment, for example, when the center of gravity GG of the handle portion 9 is located above the axis D of the electric fan 10, the electric The weight of the blower 10 and the secondary battery 17 makes it difficult for the user to freely operate the main body of the electric vacuum cleaner. On the other hand, when the center of gravity GG of the handle portion 9 is located below the axis D of the electric fan 10 and on the side close to the axis H of the connecting pipe portion 3 , the weight of the electric fan 10 causes the user to hold the When the vacuum cleaner body is held and operated, the vacuum cleaner body tends to swing around the axis H. Therefore, the main body of the vacuum cleaner may shake.

Therefore, in the vacuum cleaner 1 according to Embodiment 1, the positional relationship between the center of gravity GG of the handle portion 9 , the secondary battery 17 , the connecting pipe portion 3 , the electric fan 10 , and the shape of the handle portion 9 are optimally configured as described above. With this arrangement, the user can easily operate the vacuum cleaner body with high operability.

Next, the structure around the main body part 2 and the connection pipe part 3 of the vacuum cleaner 1 will be described with reference to FIG. 3 .

Fig. 3 is a side view of the main body portion 2 and the periphery of the connection pipe portion 3 of the vacuum cleaner 1 shown in Fig. 1 .

As shown in FIG. 3 , a power supply terminal 19 is provided in the vicinity of the connection portion connected to the connection pipe portion 3 in front of the lower arm portion 7 of the main body portion 2 . Specifically, the power supply terminal 19 is arranged on the surface (power supply terminal connection surface 18 ) of the portion of the lower arm portion 7 located below the connection portion between the lower arm portion 7 and the connection pipe portion 3 . By providing the power terminal connection surface 18, the power terminal 19 can be reliably fixed to the charging terminal of the charger (refer to FIG. 13).

The power supply terminal 19 is configured to be connectable to a power supply terminal 55 of a holder 50 (see FIG. 13 ) to be described later. Thereby, the electric power supplied from the external power supply can be supplied to the vacuum cleaner body from the power supply terminal 55 of the holder 50 via the power supply terminal 19 . In addition, the secondary battery 17 built in the lower arm portion 7 is charged with the supplied electric power. As a result, compared with a vacuum cleaner connected to an external power source via a cord reel or the like, for example, a wide cleaning area can be freely cleaned without being limited by the length of the cord reel or the like.

The power terminal 19 is arranged so as to protrude forward from the power terminal connection surface 18 so as to be substantially parallel (including parallel) to the axis H corresponding to the pipe axis of the connection pipe portion 3 .

Here, the extension line J shown in FIG. 3 represents a line extending along the bottom surface 7 a of the lower arm portion 7 .

That is, the tip of the power supply terminal 19 is arranged at a position above the extension line J that does not intersect the extension line J described above. This prevents the power supply terminal 19 from coming into contact with the ground when the vacuum cleaner body is placed on the ground, that is, when the bottom surface 7a of the lower arm portion 7 comes into contact with the ground.

Specifically, the power supply terminal 19 is arranged so that the height of the tip of the power supply terminal 19 from the point K shown in FIG. 3 located in the front part 7c of the bottom surface 7a of the lower arm part 7 is upward in the vertical direction of the cleaner body. For example about 18mm. Thereby, the power supply terminal 19 exists in the upper position which does not intersect the extension line J of the bottom surface 7a of the lower arm part 7. FIG. Therefore, the power terminal 19 is not in contact with the ground. Further, the length L of the protruding direction of the power supply terminal 19 protruding from the power supply terminal connection surface 18 is, for example, about 46 mm.

According to the above structure, in the vacuum cleaner 1 of Embodiment 1, when the vacuum cleaner body is placed on the ground, the power supply terminal 19 does not come into contact with the ground. Therefore, the possibility of damage to the power supply terminal 19 due to the contact with the ground can be reduced.

In addition, in the above-mentioned Embodiment 1, the height from the point K on the front side of the bottom surface 7a of the lower arm part 7 to the power supply terminal 19 has been described as an example of a structure of about 18 mm, but it is not limited to this. The height is not particularly limited to 18 mm as long as the height can reduce the possibility of breakage of the power supply terminal 19 . In addition, in the above-mentioned Embodiment 1, the structure in which the length L of the power supply terminal 19 is about 46 mm was demonstrated as an example, but it is not limited to this. The length is not particularly limited to 46 mm, as long as the length can reduce the possibility of breakage of the power supply terminal 19 . Furthermore, in the above-mentioned Embodiment 1, the length L of the power supply terminal 19 is described as the length of the portion protruding forward from the power supply terminal connection surface 18 , but the present invention is not limited to this. For example, the power supply terminal 19 may be configured to protrude forward from the point M shown in FIG. Thereby, it is possible to further reduce the possibility that the power supply terminal 19 comes into contact with the ground.

Moreover, as shown in FIG. 3, the upper arm part 6 of the main-body part 2 of Embodiment 1 is formed to be inclined toward the oblique rear upper side with respect to the intermediate part 8. As shown in FIG. On the other hand, the lower arm portion 7 of the main body portion 2 is formed obliquely toward the rear and lower side with respect to the intermediate portion 8 . According to this structure, the length of the handle part 9 which connects the upper arm part 6 and the lower arm part 7 can be lengthened. Therefore, even a user with a large hand can easily operate the vacuum cleaner 1 while holding the handle portion 9 . That is, for example, when the upper arm portion 6 and the lower arm portion 7 and the intermediate portion 8 are extended rearward substantially parallel (including parallel) to constitute the handle portion, the length of the handle portion cannot be sufficiently ensured. To ensure a sufficient length of the handle portion, the main body portion is enlarged. However, by configuring the handle portion 9 as described above, the length of the handle portion 9 can be sufficiently secured.

Moreover, as shown in FIG. 3, the space part 21 is formed in the part enclosed by the upper arm part 6, the lower arm part 7, the intermediate part 8, and the handle part 9 of the main-body part 2. As shown in FIG. Further, a front inclined portion 20 is formed above the space portion 21 and at the connection portion of the upper arm portion 6 and the handle portion 9 .

The front inclined portion 20 is formed in a shape inclined downward from the point N of the front end of the front inclined portion 20 in contact with the space portion 21 to the point O of the rear end of the front inclined portion 20 in contact with the space portion 21 .

Moreover, the center part 9a of the part of the side which faces the space part 21 of the handle part 9 is formed so that it may protrude toward the front in the shape which curved in the arc shape, for example. Thereby, the user can hold the arc-shaped handle portion 9 with equal force with each of the four fingers other than the thumb, which are substantially arc-shaped (including arc-shaped) when bent.

Moreover, the connection part 7b which connects the part of the side facing the space part 21 of the intermediate part 8 and the lower arm part 7 is formed in the shape recessed in a circular arc shape on the front side, for example. Thereby, the weight of the main body portion 2 can be reduced. In addition, it is possible to realize an appearance design that enables the user to easily recognize the presence of the electric fan 10 in the main body portion 2 from the shape of the recess.

As a specific dimensional relationship, the height in the vertical direction of vacuum cleaner 1 from point P at the rear end on the bottom surface 6a side of upper arm portion 6 to point O at the front end of front inclined portion 20 is, for example, about 20 mm. Moreover, the height in the vertical direction of the vacuum cleaner 1 from the point N of the front end of the front inclined part 20 to the point O of the rear end of the front inclined part 20 is about 5 mm, for example.

That is, in the case of the structure without the front inclined portion 20 , when the grip portion 9 is gripped, the user's index finger enters the narrow space above the space portion 21 . Therefore, the user may feel very difficult to hold. However, by forming the front inclined portion 20 as in the first embodiment, the width above the space portion 21 (the width in the front-rear direction of the vacuum cleaner 1) can be secured. As a result, the user can insert the index finger into the space portion 21 with a margin.

In addition, by disposing the front inclined portion 20, it is possible to disperse the portion where the weight of the vacuum cleaner 1 acts on the user's hand. Specifically, the weight of the vacuum cleaner 1 is distributed over the front inclined portion 20 and the rear portion of the upper arm portion 6 . Therefore, the weight of the vacuum cleaner 1 can be applied to the forefinger side and the base side of the thumb of the user in a distributed manner across the handle portion 9 .

Next, the relationship between the axis H, the axis G, and the axis Q around the main body portion 2 and the connecting pipe portion 3 of the vacuum cleaner 1 will be described with reference to FIG. 4 .

FIG. 4 is a side view around the main body portion 2 and the connecting pipe portion 3 shown in FIG. 1 . Specifically, FIG. 4 shows the relationship of three axes corresponding to the axis H in the pipe axis direction of the connection pipe portion 3 , the axis G of the lower arm portion 7 , and the axis Q of the handle portion 9 .

Here, the angle I shown in FIG. 4 is an angle formed by the axis H of the connecting pipe portion 3 and the axis G of the lower arm portion 7 . The angle R is an angle formed by the axis H of the connecting pipe portion 3 and the axis Q of the handle portion 9 . The angle S is an angle formed by the axis Q of the handle portion 9 and the axis G of the lower arm portion 7 .

The magnitudes of the angles are in the relationship of the angle R, the angle S, and the angle I in order from the angle with the larger angle to the angle with the smaller angle. At this time, among the three angles, the angle I constitutes the smallest acute angle, and the angle R constitutes the largest obtuse angle.

That is, the smallest acute angle I means that the lower arm portion 7 on which the secondary battery 17 is mounted is opened at a relatively small angle with respect to the axis H corresponding to the pipe axis direction of the connection pipe portion 3 . According to this structure, when the handle part 9 is held, the weight of the secondary battery 17 can be prevented from being concentrated on a part of the user's hand in the front-rear direction of the vacuum cleaner 1 .

On the other hand, the largest obtuse angle R means that the angle at which the handle portion 9 is opened with respect to the connecting pipe portion 3 is large. According to this configuration, the area of the space portion 21 between the intermediate portion 8 and the handle portion 9 can be enlarged when the user grips the handle portion 9 . Therefore, the user can easily hold the handle portion 9 .

That is, by setting the three angles in the above-described relationship as in the vacuum cleaner 1 of the first embodiment, the user can easily grasp the handle portion 9 . Furthermore, the weight of the vacuum cleaner 1 can be prevented from being concentrated on a specific part of the user's hand. Therefore, the user can easily perform cleaning for a long time.

Next, the relationship between the user's hand and the handle portion 9 in the state of gripping the handle portion 9 of the vacuum cleaner 1 will be described with reference to FIG. 5 .

FIG. 5 is a partial side view showing a state in which the user holds the handle portion 9 with the hand.

As shown in FIG. 5 , when the user holds the handle portion 9 by hand, the front inclined portion 20 touches the index finger due to the self-weight of the electric vacuum cleaner 1 . At the same time, the rear portion of the upper arm portion 6 touches the vicinity of the base of the thumb. Therefore, the weight of the vacuum cleaner 1 is distributed to the rear of the front inclined portion 20 and the upper arm portion 6 and partially applied to the hand. Thereby, the weight of the vacuum cleaner 1 can be prevented from concentrating on a specific part of the user's hand. As a result, the user can easily operate the vacuum cleaner 1 .

In addition, when the user pushes the electric vacuum cleaner 1 forward, the user holds the handle portion 9 and abuts the index finger against the front inclined portion 20 . Thereby, the vacuum cleaner 1 can be held stably, and the vacuum cleaner 1 can be easily pushed forward.

On the other hand, when the user pulls the vacuum cleaner 1 rearward, the user holds the handle portion 9 and the vicinity of the base of the thumb touches the rear portion of the upper arm portion 6 . Therefore, the user can hold the vacuum cleaner 1 stably. Moreover, the weight of the vacuum cleaner 1 is distributed to the rear of the front inclined portion 20 and the upper arm portion 6 and is partially applied to the hand. In this case, in particular, the rear portion of the upper arm portion 6 can be supported in the vicinity of the base portion of the user's thumb. Thereby, the user can easily pull the vacuum cleaner 1 rearward.

Next, the structure of the dust box 11 of the vacuum cleaner 1 of Embodiment 1 is demonstrated with reference to FIG. 6. FIG.

FIG. 6 is a perspective view of the dust box 11 . In addition, in FIG. 6, the directions shown in FIG. 6 are demonstrated as upper, lower, front, rear, left, and right.

As shown in FIG. 6, the dust box 11 is provided with the cover part 22 which can be opened and closed in the bottom part. The lid portion 22 is opened and closed by the user's operation of the opening and closing lever 23 . Specifically, when the user lowers the opening and closing lever 23 downward, the opening and closing lever 23 pushes the lid portion 22 downward. Thereby, it is comprised so that the cover part 22 may be opened.

Moreover, the dust box 11 has the 2nd opening 13 in the side surface of the front side. When the dust box 11 is attached to the connecting pipe portion 3, the second opening 13 is aligned with the first opening 12 of the connecting pipe portion 3 (see FIG. 2). Thereby, when the electric fan 10 is driven, air flows from the inside of the connection pipe portion 3 to the inside of the dust box 11 .

The dust box 11 also has a third opening 14 on the upper surface. When the dust box 11 is attached to the connecting pipe portion 3, the third opening 14 is aligned with the fourth opening 15 of the main body portion 2 (see FIG. 2). Thereby, when the electric blower 10 is driven, air flows from the inside of the dust box 11 to the inside of the electric blower 10 .

Moreover, when the 2nd opening 13 is seen from the front, the dust box 11 is provided with the 1st holding|maintenance part 25 which holds the brush 24 in the outer periphery of the right side of the opening-closing lever 23, for example. The 1st holding part 25 has the 2nd holding part 26 which holds the brush 24 below.

The cross section of the second holding portion 26 is formed in a substantially U-shape (including the U-shape), and the second holding portion 26 holds the rear end (corresponding to the handle portion) of the brush 24 inserted thereinto. On the other hand, the cross-section of the 1st holding part 25 is formed in a substantially L-shape (L-shape is included), and the 1st holding part 25 hold|maintains the center part vicinity of the brush 24 inserted. That is, the user attaches and accommodates the fur brush 24 in the dust box 11 by inserting the fur brush 24 toward the second holding portion 26 from above.

Moreover, the dust box 11 is provided with the slide part 27 which can slide in an up-down direction by a spring etc. in the upper part, for example. The cover part 22 is provided with the protrusion part 28 which protrudes upward on the front side. Thereby, the dust box 11 is connected to the connection pipe part 3 and the main body part 2 via the sliding part 27 and the protrusion part 28 of the cover part 22 .

Next, a state in which the dust box 11 is connected to the connecting pipe portion 3 and the main body portion 2 will be described in detail with reference to FIGS. 7 and 8 .

FIG. 7 is a perspective view showing a state in which the dust box 11 is attached to the connection pipe portion 3 . FIG. 8 is a perspective view showing a state in which the dust box 11 is removed from the connection pipe portion 3 .

As shown in FIG. 8, the main body part 2 has the 4th opening 15 which generate|occur|produces the suction wind from the electric fan 10, and the 1st connection recessed part 29 in which the dust box 11 is attached. On the other hand, the connection pipe part 3 has the 2nd connection recessed part 30 to which the dust box 11 is attached.

Moreover, the connection pipe part 3 has the 1st opening 12 on one side surface side, and the 1st opening 12 is opened toward the upper direction, and is used for connecting with the 2nd opening 13 of the dust box 11. As shown in FIG. Moreover, the connection pipe part 3 is provided with the brush accommodating part 31 on the other side surface side, and this brush accommodating part 31 accommodates the brush 24 when the dust box 11 is attached to the connection pipe part 3. As shown in FIG.

The brush accommodating portion 31 includes a brush accommodating side wall 32 extending in the longitudinal direction (the pipe axis direction) of the connecting pipe portion 3 , and a rear end of the brush accommodating side wall 32 which is perpendicular to the longitudinal direction of the connecting pipe portion 3 . The rear wall 33 is accommodated by the brushes extending in the intersecting direction. That is, when viewed from above, the brush housing portion 31 is formed into a substantially L-shape (including the L-shape) by the brush housing side wall 32 and the brush housing rear wall 33 .

As shown in FIG. 8, the connection pipe part 3 has the accommodation recessed part 34 which is a recessed part. When the dust box 11 is attached to the connection pipe portion 3 , the accommodating recess 34 accommodates the opening and closing lever 23 and the like of the dust box 11 .

The bottom surface 31 a of the brush storage portion 31 surrounded by the brush storage side wall 32 and the brush storage rear wall 33 is formed to be substantially flush (including flush) with the storage recess 34 . In addition, the brush accommodating part 31 may have a structure in which a step is formed between the bottom surface 31 a part surrounded by the brush accommodating side wall 32 and the brush accommodating rear wall 33 and the accommodating recess 34 .

In addition, as shown in FIG. 8 , a check valve 35 formed of, for example, rubber or the like is disposed in the first opening 12 . The check valve 35 is opened upward by the suction wind generated by the driving of the electric fan 10 . Thereby, the dust suctioned from the suction nozzle 5 enters the inside of the dust box 11 through the first opening 12 of the connecting pipe part 3 . On the other hand, when the driving of the electric blower 10 is stopped, the check valve 35 is closed. This prevents the dust inside the dust box 11 from flowing back to the connection pipe portion 3 .

Next, a method of connecting the connecting pipe portion 3 to the dust box 11 will be described.

First, the lid portion 22 side of the dust box 11 is inclined obliquely downward with respect to the connection pipe portion 3 . In the inclined state, the protrusion 28 of the dust box 11 is inserted into the second connection recess 30 of the connection pipe part 3 .

Next, the third opening 14 side of the dust box 11 is tilted downward.

Then, the sliding portion 27 of the dust box 11 is inserted into the first connecting concave portion 29 of the main body portion 2 .

The dust box 11 is connected to the connection pipe part 3 through the above steps.

At this time, in the state where the dust box 11 is connected to the connection pipe portion 3, as shown in FIG. Accommodate in a location that is not easily visible from the outside. Therefore, the aesthetic appearance of the vacuum cleaner 1 is improved.

That is, the fur brush 24 is mainly used when cleaning the inside of the dust box 11 . Therefore, in the state where the dust box 11 is detached from the connection pipe part 3, the brush 24 is arrange|positioned in the position which a user can easily attach and detach. On the other hand, in the state where the dust box 11 is attached to the connection pipe part 3, the possibility of the user using the fur brush 24 is low. Therefore, the fur brush 24 is accommodated in the fur brush accommodating part 31 so that it cannot be seen from the outside and cannot be attached or detached.

In addition, when the vacuum cleaner 1 is used, the brush storage side wall 32 and the brush storage rear wall 33 constituting the brush storage portion 31 can prevent the (bristle side) of the brush 24 from touching the user's clothes or the like. Further, by the brush housing portion 31 , scattering of dust adhering to the tip of the brush 24 can be prevented.

In addition, when the vacuum cleaner 1 is used, the brush accommodating portion 31 can prevent the brush 24 from falling out of the dust box 11 .

The dust box 11 is connected to the connection pipe part 3 and the main body part 2 as described above.

Next, the internal structure of the lower arm portion 7 of the main body portion 2 will be described with reference to FIGS. 9 and 10 .

FIGS. 9 and 10 are perspective views of the main body portion 2 and the connecting pipe portion 3 shown in FIG. 7 as viewed obliquely from below. Specifically, FIG. 9 is a perspective view showing a state in which the secondary battery 17 is accommodated. FIG. 10 is a perspective view showing a state in which the secondary battery 17 is removed. 9 and 10 illustrate a state in which the battery cover portion 37 is removed from the battery housing portion 36 .

As shown in FIG. 9 , a battery housing portion 36 is formed inside the lower arm portion 7 , and the secondary battery 17 is housed in the battery housing portion 36 . The battery cover portion 37 is attached to the battery housing portion 36 by, for example, screws or the like (not shown). With this configuration, the secondary battery 17 cannot be removed from the battery housing portion 36 unless the user intentionally removes a screw or the like.

As shown in FIG. 10 , the battery housing portion 36 includes a housing recess 38 for housing the secondary battery 17 . The storage recessed portion 38 includes a battery storage wall 39 formed in the front and having a substantially Japanese U-shaped cross section (including the Japanese U-shaped), and a rear wall 40 formed in the rear. The battery housing portion 36 further includes a plurality of ribs 41 formed on the inner side surface of the lower arm portion 7 .

The battery housing wall 39 includes a front wall 42 existing on the front side of the main body portion 2 , and two side walls 43 extending rearward from both left and right sides of the front wall 42 , and the like. The battery housing wall 39 further includes a top wall 44 formed above the front wall 42 and the side wall 43 .

In addition, the battery housing wall 39 is preferably formed of a flame-retardant material. Therefore, in Embodiment 1, the battery housing wall 39 is formed of, for example, a material made of flame-retardant polypropylene.

The battery housing portion 36 is configured as described above.

That is, the secondary battery 17 is accommodated in the battery accommodating portion 36 in a state of being sandwiched between the rear end portions of the both side walls 43 and the rear wall 40 shown in FIG. 9 . At this time, the secondary battery 17 is connected to the cable 45 for supplying electric power to the secondary battery 17 , and is accommodated in the battery accommodating portion 36 . Specifically, the cable 45 and the secondary battery 17 are electrically connected by inserting a connector (not shown) of the cable 45 and a connector (not shown) of the secondary battery 17 . Then, the cable 45 is bent at the top portion 46 along the front wall 42 in the connected state, and the secondary battery 17 is accommodated in the battery accommodating portion 36 . Thereby, the cable 45 is also accommodated in the battery accommodating portion 36 together with the secondary battery 17 . That is, the cables 45 are arranged along the front wall 42 . At this time, the cable 45 is bent at the top portion 46 of the front wall 42 closest to the battery cover portion 37 .

In addition, in Embodiment 1, in the state where the battery cover portion 37 is attached to the battery housing portion 36 , the space (gap) between the battery cover portion 37 and the top portion 46 is set to be substantially the same as the diameter of the cable 45 ( Including the same) or a width larger than the diameter of the cable 45 by about 1 mm to several mm.

That is, when the space between the battery cover portion 37 and the top portion 46 and the diameter of the cable 45 are substantially the same, the cable 45 is accommodated in a state of being in contact with the top portion 46 . Therefore, the vertical movement of the cable 45 is restricted by the battery cover portion 37 .

On the other hand, when the space between the battery cover portion 37 and the top portion 46 is formed with a width of about 1 mm to several mm larger than the diameter of the cable 45 , the cable 45 is slightly separated from the top portion 46 of the front wall 42 . was accepted. Therefore, the vertical movement of the cable 45 is restricted by the battery cover portion 37 .

Moreover, the cable 45 and the connector (not shown) are accommodated in the space enclosed by the front wall 42 and the side wall 43. At this time, the movement of the secondary battery 17 in the front-rear direction is restricted by the contact of the secondary battery 17 with the rear wall 40 and the rear end 43 a of the side wall 43 . Thereby, the contact between the secondary battery 17 and the cable 45 or the contact between the secondary battery 17 and the connector is avoided.

In addition, the power supply terminal 19 is connected to a circuit board (not shown) arranged inside the lower arm portion 7 on the back side of the ceiling wall 44 shown in FIG. 9 via a lead wire (not shown), or is directly connected to the circuit board (not shown). shown) connection. The circuit board is connected to the secondary battery 17 via the cable 45 .

In this case, the cable 45 connected to the secondary battery 17 shown in FIG. 9 needs to be of a certain length. That is, when the cable 45 is short, it may become difficult to connect the connector of the cable 45 and the connector of the secondary battery 17 during assembly. On the other hand, if the cable 45 is too long, the cable 45 may be disconnected when the cable 45 is accommodated.

Therefore, in the vacuum cleaner 1 of Embodiment 1, the length of the cord 45 is set to, for example, about 50 mm. Thereby, at the time of assembly, the connector of the cable 45 and the connector of the secondary battery 17 can be easily connected. Furthermore, in the state where the secondary battery 17 is accommodated in the battery accommodating portion 36 , the occurrence of deflection of the cable 45 can be avoided. As a result, disconnection of the cable 45 can be prevented in advance, and reliability can be improved.

The inside of the lower arm portion 7 of the main body portion 2 is configured as described above, so that the secondary battery 17 is housed in a stable state.

Next, the body 48 and the chassis 47 constituting the main body of the vacuum cleaner will be described with reference to FIG. 11 .

FIG. 11 is an exploded perspective view of the chassis 47 of the main body of the vacuum cleaner and the body 48 connected to the chassis 47 .

As shown in FIG. 11 , the chassis 47 is formed of a so-called honeycomb structure having a plurality of regular hexagonal holes 49 . With the honeycomb structure, the weight reduction of the vacuum cleaner body can be achieved, and the mechanical strength of the vacuum cleaner body can be maintained.

In consideration of strength and heat resistance, the chassis 47 and the body 48 are formed of, for example, thermoplastic resin such as polypropylene (PP), or a material obtained by mixing polypropylene with fibers or the like. That is, for the chassis 47 and the body 48, generally polypropylene or the like is suitable. However, for example, in the case where further mechanical strength or the like is desired, other materials such as ABS resin may be used to form the chassis 47 and the body 48 as necessary.

In addition, in Embodiment 1, the structure in which the chassis 47 and the body 48 are made of the same material has been described as an example, but the chassis 47 and the body 48 may be made of different materials.

In addition, in Embodiment 1, the example in which the hole 49 of the chassis 47 was formed in a regular hexagon was demonstrated, but it is not limited to this. For example, the hole may be formed in other polygons such as a triangle and a quadrangle, and the hole 49 of the chassis 47 may be formed in a circle. However, in consideration of the strength and weight reduction of the chassis 47, the shape of the hole 49 is a regular hexagon most preferable.

At this time, in order to prevent the intrusion of dust, water droplets, etc. from the outside into the inside of the main body portion 2 , it is preferable to have a structure in which no holes are formed in the body 48 other than the exhaust port 16 .

As described above, the chassis 47 has a honeycomb structure, and the body 48 has a structure in which no holes are provided in parts other than the exhaust port 16 . Thereby, the strength of the vacuum cleaner main body can be maintained while realizing the weight reduction of the vacuum cleaner 1 . Furthermore, by covering the body 48 of the chassis 47, the honeycomb structure constituted as the chassis 47 cannot be seen from the outside. Thereby, the aesthetic appearance of the vacuum cleaner body can be improved.

(Embodiment 2)

Hereinafter, the vacuum cleaner 1 according to Embodiment 2 of the present invention will be described with reference to FIGS. 12 to 19 .

In addition, Embodiment 2 mainly demonstrates the form about holding the holder of the vacuum cleaner 1 of Embodiment 1.

FIG. 12 is a perspective view showing a state in which the vacuum cleaner 1 is hung upright on the holder 50 . FIG. 13 is a perspective view showing a state in which the vacuum cleaner 1 is removed from the holder 50 . FIG. 14 is a perspective view showing a state in which the hose 57 is removed from the holder 50 . 15 : is a perspective view which shows the state which connected the hose 57 to the connection pipe part 3 of the vacuum cleaner main body. FIG. 16 is a perspective view of a portion of the base 51 of the vacuum cleaner 1 . FIG. 17 is a sectional view taken along line 17-17 of the base 51 shown in FIG. 16 . FIG. 18 is a perspective view of a portion of the holding portion 53 in a state in which the vacuum cleaner 1 is hung upright on the holder 50 . FIG. 19 is a sectional view taken along line 19-19 of the holding portion 53 shown in FIG. 18 . In addition, in FIGS. 12-14 and FIGS. 16-19, regarding the arrangement|positioning relationship of the holder 50, the direction shown in the figure is demonstrated as upper, lower, front, rear, left, and right. On the other hand, the arrangement relationship of the vacuum cleaner 1 will be described in the same manner as in FIG. 1 .

First, as shown in FIG. 12 , the holder 50 includes a base 51 , a column portion 52 , a holding portion 53 , and the like arranged below. The column portion 52 extends upward from the base 51 . The holding portion 53 is connected to the upper portion of the column portion 52 .

Moreover, as shown in FIG. 13, the holding|maintenance part 53 contains the accommodation recessed part 54 which holds the connection pipe part 3 of the vacuum cleaner 1. As shown in FIG. The holding portion 53 also includes a housing protrusion 56 protruding forward on the lower side of the housing recessed portion 54 . The housing protrusion 56 holds the vacuum cleaner 1 on the holder 50 by sandwiching the front portion 3 a of the connecting pipe portion 3 .

The holder 50 is configured as described above.

Moreover, the vacuum cleaner 1 can be hung upright on the holder 50 by the method demonstrated below.

Specifically, first, the front portion 3a side of the connection pipe portion 3 of the vacuum cleaner 1 is fitted into the housing protrusion 56 of the holding portion 53 of the holder 50 from above. Thereby, the front part 3a of the connection pipe part 3 is clamped by the accommodation protrusion 56. As shown in FIG. At the same time, the portion protruding to the left and right of the connecting pipe portion 3 abuts on the upper portion of the accommodating protrusion 56 . Thereby, the vacuum cleaner body of the vacuum cleaner 1 is attached to the holder 50 . The upper surface 53a of the holding|maintenance part 53 is comprised so that it may contact the front part 7c of the lower arm part 7 of the vacuum cleaner 1 at this time.

The housing recessed portion 54 includes a power supply terminal 55 connected to the power supply terminal 19 arranged in the connection pipe portion 3 . That is, when the vacuum cleaner 1 is hung upright on the holder 50, the power supply terminal 19 of the vacuum cleaner main body and the power supply terminal 55 of the holding part 53 of the holder 50 are connected. Thereby, power is supplied to the power supply terminal 19 from the power supply terminal 55 connected to the external power supply. And the secondary battery 17 (refer FIG. 9) built in the vacuum cleaner main body is charged with the supplied electric power.

In addition, as shown in FIGS. 13 and 14 , the holder 50 includes a base 51 arranged below. The base 51 includes a column portion 52 disposed on an upper surface 51a formed of a flat surface. On the other hand, the suction nozzle 5 of the vacuum cleaner 1 is accommodated on the upper surface 51b formed by the inclined surface of the chassis 51 .

That is, the suction nozzle 5 of the vacuum cleaner 1 is brought into contact with the inclined upper surface 51b portion of the base 51, and is slid downward along the upper surface 51b. Thereby, the vacuum cleaner 1 is accommodated and held in the holder 50 .

Moreover, the holder 50 is comprised so that the hose 57 can be detachably accommodated between the base 51 and the holder 53 .

Specifically, as shown in FIG. 15 , the hose 57 can be removed from the holder 50 , and one end 57 a of the removed hose 57 can be detachably attached to the connection pipe portion 3 of the vacuum cleaner body of the vacuum cleaner 1 . . At this time, the additional suction nozzle 58 for various applications shown in FIG. 12 and the like can be detachably attached to the other end 57b side of the hose 57 . That is, by attaching the hose 57 to the connection pipe part 3, it is set as the structure which can perform the cleaning operation as the hand-held vacuum cleaner 1. FIG.

In addition, as shown in FIG. 16 , the holder 50 includes a plurality of nozzle holes 59 formed in the upper surface 51 a of the base 51 , for example, in the shape of a circular hole. The suction nozzle hole portion 59 is inserted into the attachment portion of the above-mentioned additional suction nozzle 58 . Thereby, the additional suction nozzle 58 can be collectively accommodated in the same holder 50 together with the vacuum cleaner 1 . As a result, the holder 50 excellent in accommodating property can be realized.

In addition, the diameter dimension of the circle of the suction nozzle hole portion 59 is set to be larger than the outer diameter dimension of the attachment portion of the additional suction nozzle 58 for various applications. Thereby, it becomes easy to insert the additional suction nozzle 58 into the suction nozzle hole part 59 corresponding to it.

In addition, as shown in FIGS. 16 and 17 , the holder 50 is provided with a circular hole-shaped hose recess 60 dedicated to the hose 57 in the base 51 . The hose concave portion 60 has a convex portion 61 having, for example, a circular frustum-shaped convex portion 61 formed to protrude upward from the bottom of the base 51 . Moreover, the hose recessed part 60 is provided with the groove 62 provided in the whole periphery between the inner peripheral wall 60a of the hose recessed part 60, and the outer peripheral wall 61a of the convex part 61 of the truncated cone shape. At this time, the diameter of the circle of the circular hole-shaped hose concave portion 60 is set to be larger than the outer diameter of the attachment portion of the hose 57 . Furthermore, the maximum outer diameter dimension of the convex portion 61 of the circular frustum shape is set to be smaller than the inner diameter dimension of the hose 57 . Thereby, when the hose 57 is inserted into the hose concave portion 60 , first, the outer peripheral wall 61 a of the truncated truncated convex portion 61 enters the inside from the end portion of the hose 57 . At this time, since the inclination of the circular truncated shape of the convex portion 61 serves as a guide portion, the hose 57 can be easily put into the hose concave portion 60 . Moreover, since the outer peripheral wall 61a of the convex part 61 of the hose recessed part 60 and the inner periphery of the hose 57 are formed with sufficient clearance, insertion becomes easier. Also, after insertion, the convex portion 61 enters into the interior of the hose 57 . Thereby, the outer peripheral wall 61a of the convex part 61 can more reliably prevent the edge part of the hose 57 from being dented inward and deforming.

On the other hand, as shown in FIGS. 18 and 19 , the holding portion 53 of the holder 50 includes, for example, a convex portion 63 in the shape of a quadrangular pyramid, which is formed downward and on which the hose 57 is attached. One end 57 a of the hose 57 can be fitted to the convex portion 63 . Thereby, both ends of the hose 57 are detachably held by the convex portion 61 and the convex portion 63 of the holder 50 .

Moreover, as shown in FIG. 19, at least two side surfaces which oppose among the four side surfaces of the quadrangular pyramid shape of the convex part 63 are formed in the shape which spreads upward from below. At this time, the maximum dimension (corresponding to the diagonal line) in the cross section in the front-rear direction of the quadrangular pyramid-shaped convex portion 63 is set to be larger than the inner diameter of the hose 57 . As a result, the hose 57 and the convex portion 63 can be held in a press-fitted state. As a result, it is possible to more reliably prevent the hose 57 from falling off the convex portion 63 of the holding portion 53 due to the own weight of the hose 57 .

The holder 50 of the second embodiment is configured as described above.

Hereinafter, the attachment operation of the hose 57 to the above-mentioned holder 50 will be described.

First, for example, one end 57 a of the hose 57 is inserted into the circular hole-shaped hose recess 60 provided in the base 51 of the holder 50 for the exclusive use of the hose 57 . Then, for example, the other end 57b of the hose 57 is fitted into the convex portion 63 provided below the holding portion 53 . Thereby, the hose 57 is attached and held to the holder 50 .

In addition, in the holder 50 of Embodiment 2, accessories such as the additional nozzle 58 are collectively accommodated in the same place together with the vacuum cleaner 1 . Therefore, it is not necessary to secure additional storage places for accessories.

In addition, in Embodiment 2, the length of the column part 52 is comprised so that the length of the hose 57 may be substantially the same (including the same length). That is, the length of the hose 57 is set to the length from the bottom surface 60b of the hose recess 60 provided in the base 51 to the pressing portion of the hose 57 that is pressed into the convex portion 63 of the holding portion 53 approximately the same (including the same) length. Thereby, the hose 57 can be held and accommodated in the holder 50 in an extended state. Therefore, it is possible to prevent the occurrence of wrinkles due to the bending of the hose 57, and it is possible to improve the appearance in appearance at the time of storage. Furthermore, deterioration of the hose 57 due to wrinkles can be prevented in advance. In addition, it is not necessary to secure additional space for accommodating the hose 57 . Therefore, it is possible to configure the vacuum cleaner 1 and the holder 50 which are easy for the user to use and are excellent in accommodating properties.

As mentioned above, although Embodiment 1 and Embodiment 2 were demonstrated, the vacuum cleaner of this embodiment includes the various aspects described below.

For example, as shown in FIG. 2 , the vacuum cleaner of each embodiment is configured such that the center of gravity GG of the handle portion 9 exists between the axis D of the electric fan 10 and the axis H of the connecting pipe portion 3 in the vertical direction of the electric fan 10 . In this case, it is more preferable that the center of gravity GG of the handle portion 9 exists in a position closer to the axis D of the electric fan 10 than the axis H of the connecting pipe portion 3 .

According to this configuration, when the user cleans while holding the handle portion 9, even in the case of the structure in which the electric fan 10 is arranged above the axis H of the connection pipe portion 3, the cleaning can be performed stably.

Moreover, as another technical solution, as shown in FIG. 3, the power supply terminal 19 of the vacuum cleaner 1 is located in the position which does not intersect with the extension line J. Therefore, when the vacuum cleaner main body is placed on the ground, that is, when the bottom surface 7a of the lower arm portion 7 comes into contact with the ground, the power supply terminal 19 is configured so that the power supply terminal 19 does not come into contact with the ground.

According to the technical solution shown in FIG. 3 , when the main body of the vacuum cleaner is placed on the ground, the power terminal 19 does not come into contact with the ground. Therefore, the risk of breakage of the power supply terminal 19 can be reduced.

According to the invention related to the battery accommodating portion 36 described above using FIGS. 9 and 10 , the length of the cable 45 required for accommodating the secondary battery 17 in the battery accommodating portion 36 can be secured during production. Therefore, it is possible to reduce the possibility of disconnection of the cable 45 in the state where the secondary battery 17 is accommodated in the battery accommodation portion 36 .

According to the structure of the brush housing portion 31 shown in FIGS. 7 and 8 , in the state where the dust box 11 is connected to the connection pipe portion 3 , the brush 24 is covered by the brush housing side wall 32 and the brush housing rear wall. 33 Hidden, not easy to see from the outside. Thereby, the aesthetic appearance of the vacuum cleaner 1 can be improved.

In addition, when the electric vacuum cleaner 1 is used, the brush storage side wall 32 and the brush storage rear wall 33 are used to prevent the tip of the brush 24 from touching the user's clothes. Similarly, scattering of dust adhering to the tip of the brush 24 is also prevented. Furthermore, when the vacuum cleaner 1 is used, the brush 24 can be prevented from falling off from the dust box 11 .

According to the aspects described in FIGS. 12 and 13 , the hose 57 can be accommodated in the holder 50 in a state in which the hose 57 is extended. In addition, it is not necessary to secure additional space for accommodating the hose 57 . Therefore, it is possible to realize the holder 50 having a structure that is very easy for the user to use and has an excellent storage property.

(Embodiment 3)

Hereinafter, the vacuum cleaner 1 according to Embodiment 3 of the present invention will be described with reference to FIG. 20 .

20 is a partial side view of the main body portion 2 and the periphery of the connecting pipe portion 3 in the third embodiment.

As shown in FIG. 20 , the vacuum cleaner 1 according to the third embodiment is different from the first embodiment in that the vacuum cleaner 1 according to the third embodiment includes a point P that is inclined forward and downward toward the handle portion 9 from a point P on the rear side of the upper arm portion 6 . the rear inclined portion 64. Here, the rear back side of the upper arm portion 6 corresponds to a portion where the vicinity of the base of the thumb comes into contact when the user grips the handle portion 9 . In addition, since the other structure is the same as that of Embodiment 1, description is abbreviate|omitted.

That is, the vacuum cleaner 1 according to Embodiment 3 includes the front inclined portion 20 that is inclined rearward and downward from the front point N toward the rear point O above the space portion 21 , and the rear inclined portion 64 that is inclined from the rear The point P is inclined forward and downward toward the handle portion 9 . With this shape, when the user grips the handle portion 9 , the front inclined portion 20 reliably contacts the user's index finger, and the rear inclined portion 64 reliably contacts the vicinity of the base of the user's thumb.

Thereby, the upper arm 6 can disperse the force applied to the user's hand (particularly near the base of the index finger and thumb) during cleaning or the like, and it is possible to avoid applying a large force to the local part of the user's hand as much as possible. As a result, the user can easily operate the vacuum cleaner 1 and perform cleaning easily.

In addition, in Embodiment 3, as shown in FIG. 20, the inclination (inclination) of the front inclined part 20 was demonstrated as an example, and the inclination (inclination) is larger than the inclination (inclination) of the rear inclined part 64, but it is not limited to this. For example, the inclination of the rear inclined portion 64 may be larger than the inclination of the front inclined portion 20 .

(Other Embodiments)

The specific form which this vacuum cleaner can take is not limited to the form illustrated in the said embodiment. This vacuum cleaner can employ|adopt various forms different from the said embodiment in the range which achieves the objective of this invention. The modification of the said embodiment shown below is an example of various embodiment which this vacuum cleaner can employ|adopt.

For example, in the above-described embodiment, the configuration using the secondary battery 17 has been described as an example, but the present invention is not limited to this. For example, a non-rechargeable primary battery can also be used. In this case, a structure in which the user can easily replace the primary battery when the primary battery is exhausted is preferable. That is, for example, the battery cover portion 37 may be slidable relative to the main body portion 2 without fixing the battery cover portion 37 with screws or the like. Thereby, the user can slide the battery cover portion 37 to be easily attached to and detached from the main body portion 2 .

In addition, in the said embodiment, when the vacuum cleaner 1 was hung upright on the holder 50, the form which can charge the secondary battery 17 built in the vacuum cleaner main body was demonstrated as an example, but it is not limited to this. For example, it is good also as a form which connects the electric wire from a power supply adapter to a vacuum cleaner main body, and can use the vacuum cleaner 1 with the electric power supplied from a power supply adapter. Moreover, it is good also as a form in which the holder 50 does not have the function which can charge the secondary battery 17 built in the vacuum cleaner main body. Furthermore, it is also possible to simply provide a holder capable of being vertically hung by the electric vacuum cleaner 1 . That is, the holder may have the function of charging the secondary battery 17 or may not have the function of charging the secondary battery 17 , and either of them may be used.

In addition, in the said embodiment, although the structure which provided the brush accommodating part 31 in the connection pipe part 3 was demonstrated as an example, it is not limited to this. For example, an aspect in which the brush accommodating portion 31 is not provided in the connecting pipe portion 3 may be adopted. In this case, the user can take out the brush 24 in a state where the dust box 11 is connected to the connection pipe portion 3 .

In addition, in the said embodiment, although the axial line of the dust box 11 and the axial line of the electric fan 10 were demonstrated at the position of the axial line D which is substantially the same (including the same) as an example, it is not limited to this.
