EMBODIMENT OF THE INVENTION Hereinafter, the form (henceforth "embodiment") for implementing this invention is demonstrated in detail, referring drawings suitably.
FIG. 1 is a perspective view showing a state in which the vacuum cleaner of this embodiment is housed in a support base.
As shown in FIG. 1, the electric vacuum cleaner 100 can be changed to various usage patterns such as a handy state and a stick state for cleaning. The support base 70 in which the vacuum cleaner 100 is housed is for storing the vacuum cleaner 100 in a stick state in which the extension tube 300 (accessory) and the standard suction port 400 (accessory) are connected. 72. Further, the vacuum cleaner 100 can be used by connecting a small mouthpiece (accessory), a broom-shaped mouthpiece (accessory), an extension hose (accessory), etc., all of which are not shown. The standard mouthpiece 400 is of a power brush type in which a brush is rotated by a motor.

FIG. 2 is an exploded view of the vacuum cleaner of this embodiment. In FIG. 2 and subsequent drawings, the front, rear, left, right, up and down directions as viewed from the main body 1 of the cleaner are shown as appropriate.
As shown in FIG. 2 , the electric vacuum cleaner 100 includes a cleaner main body 1 , a dust case 2 (dust collector), a storage battery 3 and an airtight holding member 90 .

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

The body portion 10 is formed with a connection port 10a (suction port) to which the extension tube 300, the standard suction port 400 (see FIG. 1), etc. are connected. The connection port 10a is molded from the same resin as the body portion 10, the motor case portion 11, the handle portion 12, and the like. Moreover, the connection port 10a has a substantially circular opening and is formed facing forward. In addition, the connection port 10a includes accessories such as the extension pipe 300, the standard mouthpiece 400, the small mouthpiece (not shown), and the broom-shaped mouthpiece (not shown) (hereinafter collectively referred to as attachments). ) can be connected. The connection port 10a incorporates a terminal (not shown) electrically connected to the circuit board 50 (see FIG. 6). , are electrically connected and the brushes are rotated by a motor.

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

The motor case portion 11 includes an electric blower 40 (see FIG. 6) and a circuit board 50 (see FIG. 6). A circular suction port (not shown) is formed on the front surface of the motor case portion 11 through which clean air after being collected by the dust case 2 is sucked.

The handle portion 12 is provided on the rear side of the main body portion 10 and has a grip portion 12a formed in a substantially L shape. The gripping portion 12a has a first gripping portion 12a1 linearly extending in the front-rear direction so as to gradually become higher rearward, and a second gripping portion 12a2 substantially linearly extending in the vertical direction. In the gripping portion 12a, the second gripping portion 12a2 extends substantially downward from the rear end of the first gripping portion 12a1. The first gripping portion 12a1 is located on the front side of the second gripping portion 12a2. The second grip portion 12a2 is slightly inclined with respect to the vertical direction so that the upper portion faces forward. Also, the first gripping portion 12a1 and the second gripping portion 12a2 are formed in a substantially rod shape and continuously. In this way, by forming both the first gripping portion 12a1 and the second gripping portion 12a2 linearly, the user can easily recognize the position of the handle. In addition, since the first gripping portion 12a1 and the second gripping portion 12a2 are connected so as to be bent at an angle close to a right angle, when the first gripping portion 12a1 is gripped, the second gripping portion 12a2 is held by the hand. Conversely, when the second gripping portion 12a2 is gripped, the hand is less likely to slip toward the first gripping portion 12a1.
The first grip portion 12a1 extends in the front-rear direction so as to gradually become higher toward the rear side. Therefore, it is easy to insert a hand into the gap 12c (see FIG. 6).

An operation button 12b is provided on the upper surface of the first grip portion 12a1 of the handle portion 12. As shown in FIG. The operation button 12b is composed of, for example, three buttons "strong", "standard", and "off".

Release buttons 18a and 18b that are operated when accessories such as the extension tube 300 are removed are provided at the upper front end and rear upper part of the main body 10 . By depressing the release buttons 18a and 18b, the lock between the main unit 10 and the accessory is released, and the accessory can be removed from the main unit 10. FIG. The mechanism of the release buttons 18a and 18b will be described later.

Further, an airtightness holding member 90 can be attached to the front end of the body portion 10 . This airtight holding member 90 has a substantially circular cylindrical body 91 . The cylindrical body 91 has an elastic portion 91a made of a soft resin and formed in a ring shape on the distal end side. The cylindrical body 91 has a connecting portion 91b formed of a material harder than the elastic portion 91a on the base end side and connectable to the main body portion 10. As shown in FIG. The cylindrical body 91 is formed by integrally molding two different members, an elastic portion 91a and a connecting portion 91b. The elastic portion 91a is made of an elastically deformable (flexurally deformable) material such as elastomer. By attaching such an airtightness holding member 90 to the connection port 10a of the cleaner main body 1, the entire tip 90s of the airtightness holding member 90 can be brought into close contact with the floor surface, and the suction force is improved compared to the case where the airtight holding member 90 does not come into close contact. can be made Further, by forming the connection portion 91b with a hard material, the airtightness holding member 90 can be stably attached to the main body portion 10 without falling off.

In the present embodiment, the elastic portion 91a is made of an elastic material such as elastomer. For example, substantially the entire cylindrical body 91 may be made of the same material as that of the connecting portion 91b, and a ring of short hairs electrostatically implanted at the tip of the cylindrical body 91 may be provided. Even with such electrostatic flocking, it is possible to bring the tip of the airtight holding member 90 into close contact with the floor surface in the same manner as with an elastomer, thereby improving the suction force.

A longitudinally elongated fitting groove 10b is formed on the outer surface of the connection port 10a of the main body 10. As shown in FIG. The fitting groove 10b is formed on each of the left and right sides. A protruding portion (not shown) is formed at the proximal end of the connecting portion 91b so as to be engaged with the fitting groove 10b by engaging with the fitting groove 10b.

A light-emitting element may be provided on the main body 10 above the connection port 10a.

The storage battery 3 supplies electric power to a motor 40a (see FIG. 6) of an electric blower 40 that generates a suction force, and is composed of a secondary battery such as lithium ion or nickel hydrogen. The storage battery 3 has a substantially semicylindrical case 3a made of synthetic resin, and can be attached to and detached from the main body 10 by sliding the case 3a forward and backward.

FIG. 3 is a side view of the vacuum cleaner 100 in the state of FIG. 2 viewed from the left.
As shown in FIG. 3, the dust case 2 is of a cyclone type, and has the function of separating air containing dust sucked from the introduction pipe 14 into dust and air and collecting the dust. The dust case 2 is arranged in front of the motor case portion 11 with its axial direction extending in the front-rear direction, and has a substantially cylindrical storage portion 2a. A substantially rectangular inlet 2 b (see FIG. 2 ) connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust case 2 . The dust-laden air flowing into the inlet 2b becomes a swirling flow, centrifugal force acts on the dust, and after the dust and air are separated in the dust case 2, the air from which the dust is separated flows into the dust case. 2 is ejected from the rear (back).

Further, on the front surface of the dust case 2, a lid 2c that opens and closes when dust accumulated in the dust case 2 is discarded is rotatably supported via a hinge portion 2d. A lid lock mechanism 2e for unlocking the lid 2c is provided on the top of the lid 2c. Note that the internal mechanism of the dust case 2 can be configured based on Japanese Patent Application Laid-Open No. 2016-137165.

FIG. 4 is a perspective view of the vacuum cleaner of this embodiment.
As shown in FIG. 4 , in the vacuum cleaner 100 , the dust case 2 is attached below the body portion 10 and in front of the motor case portion 11 . In this case, when the dust case 2 is attached to the cleaner main body 1, the lid lock mechanism 2e is hidden on the cleaner main body 1 side. If the lid lock mechanism 2e is provided on the opposite side (outside), the lid lock mechanism 2e may be released during cleaning. However, by hiding the lid lock mechanism 2e on the side of the main body 1 of the vacuum cleaner, malfunction can be prevented. For example, when cleaning under a sofa or bed in a stick state, the cleaner body 1 may be horizontally brought close to the floor surface. At this time, if the lid lock mechanism 2e is provided on the front side, there is a possibility that the lid lock mechanism 2e will come into contact with the floor surface and be released. The positions of the lid lock mechanism 2e and the hinge portion 2d are not limited to this, and they may be provided on the left and right sides of the cleaner body 1. FIG.

Further, the dust case 2 is detachably provided with a cleaning brush 2s (see FIGS. 2 and 3). The cleaning brush 2s is arranged at a position where it is difficult to see from the outside when the dust case 2 is attached to the cleaner main body 1.例文帳に追加Therefore, it is difficult to come off during operation, and there is no need to keep the cleaning brush 2s in a separate place from the vacuum cleaner 100. - 特許庁

FIG. 5 is a plan view of the vacuum cleaner of this embodiment.
As shown in FIG. 5, the connection portion 91b of the airtightness holding member 90 has extension portions 91b1, 91b1 extending rearward on both left and right sides. A concave portion 91b2 is formed in plan view between the left extending portion 91b1 and the right extending portion 91b1. This concave portion 91b2 is fitted with a front end portion 10d1 of a protruding portion 10d formed on the top surface of the tip of the body portion 10. As shown in FIG. As a result, the airtightness holding member 90 is positioned in the front-rear direction and the left-right direction with respect to the connection port 10a (see FIG. 2).

An introduction pipe 14 formed in the main body 10 once extends obliquely rearward to the right and then downward, and is connected to the inlet 2b of the dust case 2 (see FIG. 2). As a result, a swirling flow can be generated in the housing portion 2a of the dust case 2, and the dust can be effectively separated by centrifugal force.

FIG. 6 is a sectional view taken along line VI-VI of FIG. As shown in FIG. 6, the motor case portion 11 of the main body portion 10 accommodates an electric blower 40 . The electric blower 40 is driven by a motor 40a. A circuit board 50 (circuit board) for controlling the cleaner main body 1 is housed above the electric blower 40 in the motor case portion 11 .

Also, the electric blower 40 and the circuit board 50 are arranged so as to overlap in the vertical direction. Therefore, the dimension of the cleaner main body 1 in the front-rear direction can be shortened. In addition, the motor case portion 11 of the electric blower 40 protrudes toward the handle portion 12 side, so that the front-rear direction (full length) of the main body portion 10 can be shortened.

Also, the electric blower 40 and the circuit board 50 are positioned below the first grip portion 12 a 1 of the handle portion 12 . Thereby, when the user grips and operates the first grip portion 12a1, the center of gravity of the vacuum cleaner 100 is in the vicinity of the lower portion of the first grip portion 12a1. Therefore, when using the vacuum cleaner 100 with the tip facing upward, the vacuum cleaner 100 can be stably held.

A gap 12c for inserting a hand is formed between the first grip portion 12a1 and the upper surface 11c of the motor case portion 11. As shown in FIG. A gap 12 d is formed between the second grip portion 12 a 2 and the rear surface 11 d of the motor case portion 11 .

Also, the thickness T1 of the first gripping portion 12a1 is formed thin, and the thickness T2 of the second gripping portion 12a2 is formed thicker than the thickness T1. That is, the first gripping portion 12a1 is thin, and the second gripping portion 12a2 is thick. In this way, when cleaning while gripping the second grip portion 12a2, increasing the thickness T2 of the second grip portion 12a2 makes it easier to grip deeply and increases the strength of the second grip portion 12a2. can.

The storage battery 3 can be composed of, for example, a lithium-ion battery with high energy efficiency. Moreover, the storage battery 3 is arranged below the second grip portion 12 a 2 of the handle portion 12 . By providing the storage battery 3 at the rear end of the vacuum cleaner 100 in this way, the center of gravity of the handle portion 12 is brought closer to the second grip portion 12a2, so that when the tip of the vacuum cleaner 100 is used with the tip facing upward, the operational feeling is reduced. can be lightened.

The airtightness holding member 90 is formed so that the tip (tip surface) 90s is inclined so as to recede from the upper part to the lower part so as to be substantially parallel to the surface to be cleaned when the second end 12a2 ends. there is The dust case 2 is positioned behind a plane R2 passing through the tip 90s. As a result, even when the tip 90s of the airtight holding member 90 is brought into contact with a floor surface such as flooring, the dust case 2 can be prevented from coming into contact with the floor surface.

Inside the dust case 2, a filter 5 is housed at the rear end in the axial direction of the housing portion 2a. The filter 5 is folded into a pleated shape, and can increase the filter area and reduce the pressure loss caused by the filter 5 .

The filter 5 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). A HEPA filter is an air filter that has a particle collection rate of 99.97% or more for particles with a particle size of 0.3 μm at a rated air flow rate and an initial pressure loss of 245 Pa or less.

As shown in FIG. 6, the dust case 2, the motor 40a, and the storage battery 3 are arranged on a straight line in the longitudinal direction (front-rear direction) of the cleaner body 1. As shown in FIG. In particular, the dust case 2 and the motor 40a are arranged coaxially in the longitudinal direction (front-rear direction) of the vacuum cleaner 100. As shown in FIG. The motor 40a and storage battery 3 require a large space for their installation. However, since the motor 40a and the storage battery 3 are arranged in a straight line with the dust case 2, the vertical width of the cleaner 100 can be narrowed and the cleaner 100 can be made compact.

In FIG. 6 , an arrow F indicates the flow of air sucked into vacuum cleaner 100 . Air sucked into the dust case 2 enters the electric blower 40 . The air passes around the motor 40a to cool it. Also, part of the air that has passed through the motor 40 a flows through the storage battery 3 to cool the storage battery 3 . The remaining part of the air that has passed around the motor 40 a and the air that has passed through the storage battery 3 join at the circuit board 50 to cool the circuit board 50 and then are discharged outside the system of the cleaner 100 . .
In this case, since the storage battery 3 is arranged right behind the motor 40a, it is easy to flow the cooling air in the storage battery 3. Thereby, the storage battery 3 can be efficiently cooled easily.

A circuit board housing space 50a for housing a circuit board 50 is provided in the housing above the motor 40a behind the introduction tube 14. As shown in FIG. Since the introduction pipe 14 must be formed in the front part of the cleaner 100 in order to generate a swirling flow inside the dust case 2, the front part has a certain amount of thickness in the vertical direction. Therefore, even if the housing of the cleaner 100 is slightly thickened in the vertical direction behind it to form the circuit board accommodation space 50a, the overall thickness of the cleaner 100 in the vertical direction is not increased. Therefore, if the circuit board 50 is housed in the circuit board housing space 50a, there is no need to separately provide a space for housing the circuit board 50, so an increase in the thickness of the cleaner 100 in the vertical direction can be suppressed.

Further, in this case, since the circuit board 50 is arranged at a higher position, it is possible to shorten the wire connection between the circuit board 50 and the connection port 10a having connection terminals for the accessories and the operation button 12b. Therefore, the manufacturing cost of the vacuum cleaner 100 can be reduced by shortening the wire connection and improving the workability during manufacturing.

7 and 8 are enlarged sectional views around the release buttons 18a and 18b. By pressing any of the release buttons 18a and 18b, the connection of accessories such as the extension pipe 300 and the standard mouthpiece 400 to the main body 1 of the cleaner can be released. FIG. 7 shows a state in which neither release button 18a nor 18b is pressed. In this state, when the release button 18a is first pressed, the release button 18a and its base end portion 18a1 tilt forward and downward. As a result, a predetermined lock mechanism is released, and the accessory can be removed from the cleaner main body 1. - 特許庁

On the other hand, as shown in FIG. 8, when the release button 18b is pressed, the release button 18b and its base end 18b1 tilt forward and downward. A long shaft-like member 18c is arranged between the base end portion 18a1 of the release button 18a and the base end portion 18b1 of the release button 18b. When the base end portion 18b1 of the release button 18b tilts forward and downward, the base end portion 18b1 pushes one end of the shaft-like member 18c forward. Then, the shaft-shaped member 18c moves forward, and the other end presses the base end 18a1 of the release button 18a, and the release button 18a and its base end 18a1 tilt forward and downward. Thereby, as shown in FIG. 8, the predetermined lock mechanism is released, and the airtightness holding member 90 can be removed from the cleaner main body 1. As shown in FIG.

By providing the release button 18b in addition to the release button 18a, the user of the vacuum cleaner 100 can operate the release button 18b while holding the first grip part 12a1 to remove the accessory from the cleaner body 1. can be done.

FIG. 9 is a side view of the vacuum cleaner viewed from the right side.
Attachment/detachment mechanisms 2 g and 19 for attaching/detaching the dust case 2 to/from the cleaner body 1 are provided at the lower rear end of the dust case 2 and the lower front end of the cleaner body 1 . That is, when attaching the dust case 2 to the cleaner main body 1, the attachment/detachment mechanism 2g and the attachment/detachment mechanism 19 are connected by a predetermined mechanism. The attachment/detachment mechanisms 2g and 19 extend to the lowest part of the vacuum cleaner 100. In particular, the lower end of the attachment/detachment mechanism 19 is the lowest part of the vacuum cleaner 100, and the leg portion 19a is provided below the attachment/detachment mechanism 19. It is A leg portion 3n is also provided at the bottom end of the rear end of the storage battery 3. As shown in FIG.

When the vacuum cleaner 100 is placed on a horizontal plane F with the lower side of the vacuum cleaner 100 facing down, heavy parts such as the motor 40a and the storage battery 3 may be present in the lower rear portion of the vacuum cleaner 100. Vacuum cleaner 100 is supported on horizontal plane F by legs 19a and 3h. At this time, the leg portion 19a is located at the lowest end of the vacuum cleaner 100, and the leg portion 19a is located at an intermediate position in the longitudinal direction of the vacuum cleaner 100. The cleaner 100 faces obliquely upward as shown in FIG. Therefore, the tip of the connection port 10a, which serves as a suction port, also faces obliquely upward. Therefore, the tip 90s of the airtight holding member 90 also faces obliquely upward. Therefore, when the vacuum cleaner 100 is supported on the horizontal plane F, dust remaining inside the connection port 10a and the airtightness holding member 90 is less likely to spill out.

As shown in FIG. 9, the storage battery 3 can be charged by connecting an AC adapter (not shown) to a terminal t provided on the right side of the cleaner body 1 .

FIG. 10 is a side view of the vacuum cleaner of this embodiment as seen from the left side.

11 is a cross-sectional view taken along line XI-XI of FIG. 10. FIG.
In the housing structure of the vacuum cleaner 100, the housing 20 covering the motor 40a and the circuit board 50 is a single flame-retardant case. Since the motor 40a and the circuit board 50 are not covered with a double or triple housing structure, the weight of the electric vacuum cleaner 100 can be reduced.

12 is a cross-sectional view taken along the line XII-XII of FIG. 10. FIG.
As shown in FIG. 12, the storage battery 3 is an assembled battery, and five electric cells 3h (battery cells) are arranged in a case 3a, two each vertically and horizontally, and one in the center. are placed. In this way, by orienting the axial direction of the cell 3h in the front-back direction, the width of the storage battery 3 can be made narrower than when the axial direction of the cell 3h is oriented in the left-right direction.

Further, the unit cell 3h is accommodated in the case 3a while being held by a holding member 3j made of synthetic resin. The holding member 3j is configured such that a gap 3k is formed between the upper cell 3h and the lower cell 3h.

By forming such a gap 3k, air can flow around each cell 3h, and each cell 3h can be effectively cooled.

FIG. 13 is a plan view of the vacuum cleaner connected with the accessory.
As shown in FIG. 13 , the electric vacuum cleaner 100 is configured such that the extension pipe 300 can be connected while the airtightness maintaining member 90 is connected to the cleaner main body 1 . Thus, even if the airtightness holding member 90 is connected to the main body 1 of the cleaner, the position of the connection port 10a to which the extension pipe 300 is connected does not change. Therefore, the total length L connecting the cleaner main body 1, the extension pipe 300 and the standard suction port 400 can be kept short. As a result, the position of the standard mouthpiece 400 is close to the user's hand, so that handling is improved and usability can be improved.

In the electric vacuum cleaner 100 shown in FIG. 13, even if the extension pipe 300 to which the standard suction port 400 is connected is removed from the stick state to make it handy, the airtightness holding member 90 is still attached to the cleaner body 1. . Therefore, cleaning can be performed while the suction force is increased.

In the embodiment of FIG. 13, the case where the extension pipe 300 and the standard mouthpiece 400 are connected to the electric vacuum cleaner 100 has been described as an example, but the present invention is not limited to this embodiment. For example, the standard suction mouthpiece 400 can be directly connected to the connection port 10a and used as a handy electric vacuum cleaner 100. - 特許庁As a result, the airtightness with the floor surface is enhanced by the airtightness holding member 90, so that the suction force can be enhanced.

In this way, in the vacuum cleaner 100, various accessories (attachments) can be attached and detached while the airtightness holding member 90 is attached to the vacuum cleaner body 1, and cleaning is performed by quickly switching the usage mode of cleaning. be able to. Further, since the airtightness holding member 90 can be left attached to the vacuum cleaner main body 1, the handy electric vacuum cleaner 100 to which the airtightness holding member 90 is attached can perform cleaning while securing a high suction force.

FIG. 14 is a perspective view showing the support base of the vacuum cleaner. Note that the support base 70 shown in FIG. 14 is in a state in which the vacuum cleaner 100 and all accessories (attachments) are removed. As shown in FIG. 14, the support base 70 is composed of a base portion 71 and a stand portion 72 .

The base portion 71 has a substantially rectangular mounting surface 71a on which the standard mouthpiece 400 (see FIG. 1) is mounted. The mounting surface 71a is provided with a locking portion 71a1 for locking the standard mouthpiece 400 from sliding forward. Further, since the base portion 71 gradually becomes higher toward the rear side in the front-rear direction, the stand portion support portion 71b has an inclination angle of 1 degree with respect to the horizontal plane. Therefore, even when the support base 70 is stored near the wall, it is possible to prevent the electric vacuum cleaner 100 from hitting the wall.

The stand portion 72 extends vertically upward from a stand portion support portion 71b provided behind the mounting surface 71a. An engaging portion 72a, which is a concave portion recessed rearward along the vertical direction, is provided in the upper front portion of the stand portion support portion 71b. Further, the upper end portion of the stand portion 72 is provided with an inclined surface 72b inclined toward the engaging portion 72a. As a result, the inclined surface 72b guides and facilitates installation when supporting in a stick state. The installation method will be described later.

FIG. 15 is a side view showing the vacuum cleaner and the support base.
As shown in FIG. 15 , the vacuum cleaner 100 is supported by the support base 70 with the extension pipe 300 and the standard mouthpiece 400 connected to the cleaner body 1 . Specifically, a substantially L-shaped hook (projection projecting downward) 301 is provided at the tip of the extension tube 300 with the tip facing downward. Then, the hook 301 is engaged with the engaging portion 72a (FIG. 14) provided on the stand portion 72 of the support base 70. As shown in FIG. Also, the standard mouthpiece 400 is locked to the locking portion 71a1 on the mounting surface 71a. As a result, the entire electric vacuum cleaner 100 can be supported by the support base 70 with the main body 1 of the vacuum cleaner as the upper side and the standard suction port 400 side as the lower side, and the size of the support base can be reduced. The position of the hook 301 is not limited to this, and it is possible to store it in a stick state in which the extension pipe and the standard suction port are connected to the cleaner body by providing it in a place other than the cleaner main body 1, such as the upper end of the standard suction port 400. However, it does not matter because the effect of miniaturization of the support base is achieved.

In order to install and maintain the entire vacuum cleaner 100 on the support base 70, the extension tube 300 adopts resin (glass-filled polypropylene or carbon) that is hard to deform. As a result, even when the hook 301 at the tip of the extension tube 300 is engaged with the support base 70, deformation during long-term use is suppressed.

In this way, the vacuum cleaner 100 can be installed on the support base 70 in a stick state, so that the vacuum cleaner 100 can be immediately used in a stick state when cleaning next time.

Further, the mounting surface 71 a of the base portion 71 is formed so as to extend forward from the extension pipe 300 . As a result, the standard suction port 400 can be supported by the mounting surface 71a in a state in which the extension pipe 300 is connected to the standard suction port 400, that is, in a state in which the extension pipe 300 and the standard suction port 400 are connected to the cleaner body 1 (stick state). can be done. Therefore, the vacuum cleaner 100 can be stably supported by the support base 70 .

Furthermore, as another embodiment of the present invention, a structure in which a charging terminal is provided in the aforementioned engaging portion 72a and a connection terminal is provided in the hook 301 so that charging can be performed in an installed state will be described.
In the above-described embodiment, the engaging portion 72a and the hook 301 are engaged to support the entire vacuum cleaner 100 on the support base 70, but the engaging portion 72a is provided with the charging terminal and the hook 301 is provided with the connecting terminal. This makes it possible to charge the battery while it is installed.
In other words, the concave portion has a stand-side terminal, and the convex portion has a body-side terminal that contacts the support-side terminal in a state of being engaged with the concave portion. By providing a storage battery that is charged in a state in which it is in contact with the support side terminal, it is possible to charge the device in an installed state.
As a result, the trouble of connecting the AC adapter can be saved, and the battery can be easily charged.

FIG. 16 is a usage diagram for cleaning a floor surface with a stick vacuum cleaner.
In FIG. 16, the extension tube 300 and the standard mouthpiece 400 are connected to the electric vacuum cleaner 100 (with the airtightness holding member 90 attached) to make a stick state, and the electric vacuum cleaner 100 protrudes forward from the user to cover the floor surface. This is the case for cleaning. In this case, the user can perform cleaning while gripping the second grip portion 12a2 of the handle portion 12 and moving the vacuum cleaner 100 back and forth. Further, although not shown, when cleaning the floor surface with the electric vacuum cleaner 100 positioned on the left and right sides of the user, the user holds the first holding portion 12a1 of the handle portion 12 and , the vacuum cleaner 100 can be moved back and forth. In this way, when the user cleans the floor surface, he/she can clean by changing the position of the handle portion 12 .

FIG. 17 is a usage diagram for cleaning a high place with a stick vacuum cleaner.
By the way, with a vacuum cleaner whose center of gravity is on the tip side when it is in a stick state (see Japanese Patent Application Laid-Open No. 2016-137165), when cleaning a place higher than the floor surface, the user tends to move the vacuum cleaner. Since it is necessary to lift the tip upward, a burden is easily applied to the wrist.

Therefore, in the present embodiment, as shown in FIG. 17, the electric blower 40 (see FIG. 6) and the storage battery 3, which are heavy components of the vacuum cleaner 100, are positioned close to the handle portion 12 (positions close to hand). , the center of gravity G of the vacuum cleaner 100 becomes closer to the hand of the user. As a result, even when the vacuum cleaner 100 is in a stick state and the vacuum cleaner 100 is used to clean a place higher than the floor surface, it becomes easy to clean, and usability can be improved. In FIG. 17, the case of cleaning the stairs has been described as an example, but it is also effective when lifting the electric vacuum cleaner 100 to clean the panel of the indoor unit of the air conditioner.

Also, when using the vacuum cleaner 100 in a stick state, when removing dust remaining on the corners of the stairs, the extension tube 300 and the standard suction port 400 are removed from the vacuum cleaner 100 to make it handy. do. In this case, since the vacuum cleaner 100 is still attached with the airtightness holding member 90, it is possible to perform cleaning with an increased suction force, thereby preventing dust from being left unabsorbed.
In addition, the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the described configurations.
