DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, modes for carrying out the present invention (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings as appropriate.

FIG. 1 shows a perspective view of a vacuum cleaner 100 according to an embodiment stored in a support stand 70. In the drawings from FIG. 1 onwards, the front, back, left, right, top and bottom directions as seen from the cleaner body 1 are shown as appropriate.

The vacuum cleaner 100 can be used for cleaning in various usage modes, such as a handy state (see FIG. 2) and a stick state (see FIGS. 1 and 16). The support stand 70 in which the vacuum cleaner 100 is housed includes a base portion 71 and a stand portion 72.

As shown in FIG. 1, the vacuum cleaner 100 is housed in a stick state with an extension pipe 300 (accessory) and a standard suction port 400 (accessory) connected to the support stand 70.

The vacuum cleaner 100 can be used by connecting a small suction spout (accessory), a broom-shaped suction mouth (accessory), an extension hose (accessory), etc., all of which are not shown. Note that the standard suction port 400 is of a power brush type in which a brush is rotated by a motor.

FIG. 2 shows a perspective view of the vacuum cleaner 100 of the embodiment in a handy state. FIG. 4 shows an exploded perspective view of the vacuum cleaner 100 in a handy state.

The vacuum cleaner 100 includes a vacuum cleaner main body 1, a dust case 2 (dust collector), a storage battery 3, and a handy cleaning member 90.

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

As shown in FIG. 3, the main body portion 10 is formed with a connection port 10a which is a suction port to which an extension pipe 300, a standard suction port 400 (see FIG. 1), etc. are connected. The connection port 10a forms an inlet of the suction pipe 10b.

The connection port 10a is formed with a substantially circular opening at the front. The connection port 10a is molded from the same resin as the main body portion 10, the motor case portion 11, the handle portion 12, and the like. The upper plate 11d of the motor case portion 11 has an inclination that descends toward the rear.

The connection port 10a is configured to allow attachments such as an extension pipe 300 (see FIG. 1), a standard suction port 400, a small suction port (not shown), a broom-shaped suction port (not shown), etc. to be connected. A terminal (not shown) electrically connected to the circuit board 50 (see FIG. 8) is built into the connection port 10a. When a motorized accessory, such as the standard mouthpiece 400 shown in FIG. 1, is connected, the brush is rotated by an electrically connected motor (not shown).

A dust case 2 is detachably attached to the main body 10 shown in FIG. 4, and an introduction pipe 14 (see FIGS. 7 and 8) sends air containing dust sucked in from the connection port 10a into the dust case 2. It is equipped with FIG. 5 shows an exploded side view of the vacuum cleaner 100 in a handy state. FIG. 6 shows a view taken in the I direction of FIG. 2.

The motor case portion 11 includes a fan motor 40 (see FIG. 8) and a circuit board 50. The circuit board 50 is arranged along or substantially parallel to the upper plate 11d of the motor case portion 11 that is inclined rearward and downward.

A circular suction port 11a (see FIG. 4) is formed on the front surface of the motor case portion 11, through which clean air after dust collection in the dust case 2 is sucked.

The handle portion 12 shown in FIG. 2 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 includes a first gripping portion 12a1 that extends linearly in the front-rear direction so as to be gradually higher toward the rear, and a second gripping portion 12a2 that extends linearly in an approximately vertical direction. The first grip part 12a1 is located on the front side of the second grip part 12a2. The first grip portion 12a1 extends in the front-rear direction so as to be gradually higher toward the rear. The second gripping portion 12a2 extends diagonally downward from the rear end of the first gripping portion 12a1 toward the rear. Therefore, it is easy to put a hand into the gap 12c.

The first gripping portion 12a1 and the second gripping portion 12a2 are substantially rod-shaped and continuously formed. By configuring the first gripping part 12a1 and the second gripping part 12a2 in a straight line, the user can easily recognize the position of the handle.

In addition, since the first gripping part 12a1 and the second gripping part 12a2 are connected so as to be bent at an angle close to a right angle, when the first gripping part 12a1 is gripped, the hand is moved toward the second gripping part 12a2. On the other hand, when gripping the second gripping part 12a2, it is difficult for the hand to shift toward the first gripping part 12a1.

Therefore, it becomes easy to put a hand into the gap 12c (see FIG. 2).

As shown in FIG. 2, an operation button 12b is provided on the upper surface of the first grip part 12a1 of the handle part 12. The operation buttons 12b include, for example, three buttons: "Strong", "Standard", and "Off".

A release button 18a is provided at the upper front end of the main body 10 to be operated when removing accessories such as the extension tube 300. By pressing the release button 18a, the main body 10 and the accessory are unlocked, and the accessory can be removed from the main body 10. Since only one release button 18a is provided, the vacuum cleaner 100 can be made smaller and lighter.

As shown in FIG. 4, a handy cleaning member 90 can be attached to the front end of the main body 10. The handy cleaning member 90 has a substantially cylindrical body 91 . The cylindrical body 91 has a brush portion 91a on the distal end side in which soft bristles 91a1 are planted in bundles. The cylindrical body 91 is made of a hard material and has a connecting part 91b connectable to the main body part 10. The cylindrical body 91 has a brush portion 91a and a connecting portion 91b integrally formed. By forming the connecting portion 91b with a hard material, the handy cleaning member 90 can be stably attached to the main body portion 10 without falling off. Since the handy cleaning member 90 has the brush portion 91a, the vacuum cleaner 100 can suck the dirt while scraping out the dirt with the brush portion 91a, so that cleaning can be performed efficiently. Therefore, the usability of the vacuum cleaner 100 is improved.

Since the cylindrical body 91 has the brush portion 91a with the annular short bristles 91a1 implanted at the tip, the tip of the handy cleaning member 90 can be brought into close contact with the floor surface, and the suction power can be improved.

Fitting grooves 10e and 10c (see FIG. 5), which are elongated in the vertical direction, are formed on the outer surface of the connection port 10a of the main body portion 10 shown in FIG. 4. The fitting groove 10e is formed with one groove on each of the left and right sides, and a fitting groove 10c is formed at the bottom thereof. A protrusion (not shown) is formed at the base end of the connecting portion 91b to be engaged with and engaged with the fitting groove 10e and the fitting groove 10c. Since vertically elongated fitting grooves 10e and 10c are formed on the outer surface of the connection port 10a of the main body 10, the handy cleaning member 90 can be easily attached to the connection port 10a of the main body 10, improving usability.

The storage battery 3 shown in FIG. 6 is composed of a secondary battery such as a lithium ion battery or a nickel metal hydride battery, and supplies electric power to a motor 40a of a fan motor 40 that generates suction force. As shown in FIG. 4, the storage battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin. The case 3a can be attached to and detached from the main body 10 by sliding it in the front-back direction.

As shown in Fig. 5, the dust case 2 is of a cyclone type, and separates the air containing dust sucked in from the introduction pipe 14 (see Figs. 7 and 8) into dust and air, and collects the dust. Has a function. FIG. 7 shows a top view of the vacuum cleaner 100 of the embodiment.
The dust case 2 is disposed in front of the motor case portion 11 with the axial direction being the front-rear direction, and has a substantially cylindrical housing portion 2a. A substantially rectangular inlet 2b (see FIG. 4) connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust case 2. The air containing dust that has flowed into the inlet 2b becomes a swirling flow, centrifugal force acts on the dust, and the dust and air are separated in the dust case 2.The air from which the dust has been separated flows into the dust case 2. It is discharged from the rear part (arrow M in Fig. 8).

As shown in FIG. 4, a lid 2c is rotatably supported on the front surface of the dust case 2 via a hinge portion 2d, which is opened and closed when disposing of the dust accumulated in the dust case 2. Further, a lid locking mechanism 2e for unlocking the lid 2c is provided at the top of the lid 2c.

As shown in FIG. 2, in the vacuum cleaner 100, the dust case 2 is attached below the main body part 10 and in front of the motor case part 11. In this case, when the dust case 2 is attached to the cleaner body 1, the lid locking mechanism 2e is hidden behind the cleaner body 1 side. This is because if the lid locking mechanism 2e is provided on the opposite side (outside), there is a risk that the lid locking mechanism 2e will be released during cleaning. However, by making the lid locking mechanism 2e hidden behind the cleaner main body 1 side, malfunction can be prevented.

Further, a cleaning brush 2s (see FIG. 4) is detachably provided in the dust case 2. 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 body 1. Therefore, it is difficult to come off during operation, and there is no need to store the cleaning brush 2s in a separate location from the vacuum cleaner 100.

As shown in FIG. 7, the introduction pipe 14 formed in the main body 10 first extends obliquely to the right rear, and then extends downward, and is connected to the inlet 2b of the dust case 2 (see FIG. 4). . Through the introduction pipe 14, a swirling flow can be generated within the housing portion 2a of the dust case 2 shown in FIG. Due to the swirling flow within the storage section 2a, dust can be effectively separated by centrifugal force.

FIG. 8 shows a cross-sectional view taken along line II-II in FIG.

The motor case portion 11 of the main body portion 10 houses a fan motor 40 and a first elastic member 60 and a second elastic member 70 around the fan motor 40 . A circuit board 50 for controlling the cleaner body 1 is housed in the motor case portion 11 above the fan motor 40 .

The fan motor 40 and the circuit board 50 are arranged to overlap in the vertical direction. Therefore, the longitudinal dimension of the cleaner body 1 can be shortened. Furthermore, since the fan motor 40 is formed so that the motor case portion 11 overlaps with the handle portion 12 side, the dimension of the main body portion 10 in the front-rear direction (total length) can be shortened.

Further, the fan motor 40 and the circuit board 50 are located below the first grip portion 12a1 of the handle portion 12. Thereby, when the user grips and operates the first grip part 12a1, the center of gravity of the vacuum cleaner 100 is located near the bottom of the first grip part 12a1. Therefore, when using the vacuum cleaner 100 with the tip facing upward, the vacuum cleaner 100 can be stably held.

Furthermore, a gap 12c for inserting a hand is formed between the first gripping part 12a1 and the second gripping part 12a2 and the top plate 11d of the motor case part 11.

The upper surface plate 11d of the motor case portion 11 is formed with an inclination such that the rear side is downwardly inclined.

The circuit board 50 is arranged along the upper surface plate 11d of the motor case portion 11 or with an inclination close to parallel to the upper surface plate 11d. Thereby, the space inside the motor case portion 11 can be widely utilized without narrowing the gap 12c for inserting the hand. Therefore, the vertical dimensions of the motor case portion 11 can be shortened, and the vacuum cleaner main body 1 can be made smaller.

The storage battery 3 is arranged below the second grip part 12a2 of the handle part 12. The storage battery 3 can be configured with, for example, a lithium ion battery with high energy efficiency.

A filter 5 is housed in the dust case 2 at the rear end of the housing portion 2a in the axial direction. The filter 5 is folded into a pleat shape, and the filter area can be increased, and the pressure loss caused by the filter 5 can be reduced. The filter 5 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter).

(First embodiment)
FIG. 9(a) is a side view of the fan motor 40, the first elastic member 60, and the second elastic member 65, and FIG. 9(b) is a side view of the fan motor 40, the first elastic member 60, and the second elastic member 65. A perspective view seen diagonally from above and from the front is shown.
As shown in FIGS. 9(a) and 9(b), the fan motor 40 includes a casing 40b having an intake hole 40b1 protruding forward and a tapered portion 40b2 tapering toward the rear, and an impeller 40c contained in the casing 40b. and a motor section 40a that drives this impeller 40c.

FIG. 10(a) shows a front view of the first elastic member 60, and FIG. 10(b) shows a rear view of the first elastic member 60.
As shown in FIGS. 10(a) and 10(b), the first elastic member 60 has a cylindrical shape, and has an annular portion 60a formed of an annular surface on the inside, and an annular portion 60a along the circumference. A plurality of protrusions 60b are arranged radially at equal intervals. Each protrusion 60b is arranged at intervals of approximately 15 degrees. Note that this interval may be larger or smaller than about 15 degrees. The protrusion 60b widens rearward in a tapered shape. The tapered shape of the protrusion 60b is configured to follow the tapered portion 40b2 of the casing 40b. By providing the protrusions 60b at equal intervals in this manner, the motor section 40a can be held in a well-balanced manner, the vibration-proofing effect can be enhanced, and noise caused by vibration of the motor can also be prevented. Furthermore, by providing a plurality of protrusions 60b, the motor section 40a can be more firmly and stably held within the motor case section 11. Note that the protrusion 60b may have 10 or more protrusions as shown in the figure, or may have fewer than 10 protrusions. Although the first elastic member 60 is shown as a projection 60b in FIGS. 9 and 10, the first elastic member 60 is not limited to this, and may be supported by an annular surface along the tapered portion 40b2 of the casing 40b.

The annular portion 60a of the first elastic member 60 is attached to the outer periphery of the protruding intake hole 40b1 of the casing 40b, and the protrusion 60b is in close contact with the tapered portion 40b2 at the rear of the protruding intake hole. This increases the area in which the fan motor 40 and the first elastic member 60 come into close contact with each other, making it possible to better absorb the vibrations of the fan motor 40 and thereby reducing the vibrations of the fan motor 40.
FIG. 11(a) shows a front view of the second elastic member 65, and FIG. 11(b) shows a rear view of the second elastic member 65.
As shown in FIGS. 11(a) and 11(b), the second elastic member 65 has a cylindrical shape, and has eight circular parts 65a, two rectangular parts 65b, and 12 protrusions on the outer periphery. 65c is placed.
The eight circular parts 65a are arranged at positions symmetrical with respect to the center of the cylindrical circle of the second elastic member 65. Note that the circular portion 65a may have 10 or less circular portions as shown in FIG. 11, or may have more than 10 circular portions.
The two rectangular portions 65b are arranged point-symmetrically with respect to the center of the cylindrical circle of the second elastic member 65. Note that the rectangular portion 65a may have five or less rectangular portions as shown in FIG. 11, or may have more than five rectangular portions.
The circular portion 65a and the rectangular portion 65b are sandwiched between the motor case portion 11 and suppress movement of the fan motor 40 in the radial direction.

The twelve protrusions 65c are arranged at equal intervals on the circumference, and can suppress the movement of the fan motor 40 in the axial direction, thereby reducing vibrations of the fan motor 40 and further preventing noise. Note that the protrusion 65c may have ten or more circular parts as shown in FIG. 11, or may have fewer than ten circular parts.
FIG. 13 shows a set of the motor case 30, the first elastic member 60 or the third elastic member 61 of the second embodiment described later, the second elastic member 65, and the fan motor 40, in an enlarged view of part P in FIG. FIG. 13 shows a perspective view of the motor case 30 as seen from the diagonally upper left rear side.

As shown in FIGS. 12 and 13, the outer circumferential portion 60f of the first elastic member 60 is held between the circular ribs 30a of the motor case 30 to suppress movement of the fan motor 40 in the radial direction. Further, the front portion 60c of the first elastic member 60 is in pressure contact with the partition plate 30b of the motor case 30, and suppresses movement of the fan motor 40 in the axial direction.

Further, the front part 60c of the first elastic member 60 and the partition plate 30b of the motor case 30 come into pressure contact, and the front back part 60d of the first elastic member 60 and the front part of the protruding intake hole 40b1 of the casing 40b come into pressure contact with each other. , ensuring airtightness between the motor case 30 and the fan motor 40. Therefore, there is no need for an additional member to ensure airtightness in the part, making it possible to reduce the number of parts and reduce the weight.

Further, the diameter of the hole 60e on the intake hole side of the first elastic member 60 is larger than the diameter of the hole on the intake hole side of the fan motor 40. Further, the front surface portion 60c of the first elastic member 60 on the intake hole side is configured such that the hole diameter decreases from the front to the rear. This smoothes the flow of air flowing into the fan motor 40 and reduces loss of intake air.
Therefore, according to this embodiment, the first elastic member 60 can absorb the shock when the fan motor 40 is driven and can prevent the fan motor 40 from touching the main body 100, ensuring secure fixation to the main body and improving quality. improves. By providing the first elastic member 60, vibration mainly caused by the impeller 40c included in the fan motor 40 can be reduced. Furthermore, by providing the second elastic member 65, vibrations mainly caused by the motor 40a can be reduced. Note that although this embodiment discloses a configuration that includes both the first elastic member 60 and the second elastic member 65, the present invention is not limited to this, and vibrations can be reduced even if either one is present. However, by including both elastic members, a vacuum cleaner with lower vibration and noise can be realized.

(Second embodiment)
Next, a modification of the first elastic member 60 described above will be described using FIGS. 12(a) and 12(b). In addition, in this embodiment, only the first elastic member 60 is changed to a third elastic member 61, and the other structures are the same. FIG. 12(a) shows a front view of the third elastic member 61, and FIG. 12(b) shows a rear view of the third elastic member 61 of the second embodiment. As shown in FIG. 12, the third elastic member 61 has a cylindrical shape, and has an annular portion 61a formed of an annular surface on the inside, and a plurality of elastic members regularly arranged along the circumference. A protrusion 61b is arranged. By regularly providing the protrusions 61b while maintaining the triangular shape, the fan motor 40 can be held in a well-balanced manner, and the vibration isolation effect can be enhanced. Furthermore, noise caused by vibration of the motor can also be prevented.
FIG. 14 shows the motor case 30. The motor case has a substantially cylindrical shape, and has a circular rib 30a and a partition plate 30b inside.

FIG. 15 shows a side view of the vacuum cleaner 100 viewed from the right side.

Attachment and detachment mechanisms 2g and 19 for attaching and detaching the dust case 2 to and from the cleaner body 1 are provided at the lower rear end of the dust case 2 and at the lower front end of the cleaner body 1. That is, when attaching the dust case 2 to the cleaner body 1, the attachment/detachment mechanism 2g and the attachment/detachment mechanism 19 are connected by a predetermined mechanism. The attachment/detachment mechanism 2g, 19 extends to the lowest part of the vacuum cleaner 100, and in particular, the lower end of the attachment/detachment mechanism 19 is the lowest part of the vacuum cleaner 100, and the leg part 19a is provided below the attachment/detachment mechanism 19. ing. A leg portion 3n is also provided at the rearmost lower end of the storage battery 3. As shown in FIG. 17, when the vacuum cleaner 100 is placed with its lower side facing down on a horizontal floor surface Y, heavy components such as the fan motor 40 and the storage battery 3 are placed at the rear of the vacuum cleaner 100. The vacuum cleaner 100 may be located at the bottom, and the vacuum cleaner 100 is supported on the horizontal floor surface Y by the legs 19a and 3n. At this time, the leg part 19a is located at the lowest end of the vacuum cleaner 100, and since the leg part 19a is located at an intermediate position in the longitudinal direction of the vacuum cleaner 100, the vacuum cleaner 100 is placed on the horizontal floor surface Y. As shown in FIG. 15, the vacuum cleaner 100 has its front facing diagonally upward.

Therefore, the distal end of the connection port 10a serving as a suction port also faces diagonally upward, and the distal end 90s of the handy cleaning member 90 also faces diagonally upward. Therefore, when the vacuum cleaner 100 is supported on the horizontal floor surface Y, dust remaining inside the connection port 10a and the handy cleaning member 90 is unlikely to spill out to the outside.

As shown in FIG. 15, 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. 16 shows a front view of the vacuum cleaner 100 with the accessory extension tube 300 and standard suction port 400 connected.

The vacuum cleaner 100 is configured such that an extension tube 300 can be connected to the vacuum cleaner main body 1 with the handy cleaning member 90 connected thereto. In this way, even if the handy cleaning member 90 remains connected to the cleaner body 1, the position of the connection port 10a (see FIG. 4) for connecting the extension tube 300 does not change. Therefore, the total length of the connection between the cleaner body 1, the extension tube 300, and the standard suction port 400 can be kept short. This brings the standard suction port 400 closer to the user's hand, making it easier to handle the vacuum cleaner 100 and improving its usability.

Even if the vacuum cleaner 100 is changed from the stick state shown in FIG. 16 to the handy state shown in FIG. It remains attached. Therefore, cleaning can be performed with increased suction power.

In addition to using the vacuum cleaner 100 by connecting the extension tube 300 and the standard suction port 400, for example, the vacuum cleaner 100 can be used as a handy vacuum cleaner 100 by directly connecting the standard suction port 400 to the connection port 10a.

In this way, in the vacuum cleaner 100, various accessories (attachments) can be attached and detached while the handy cleaning member 90 remains attached to the cleaner body 1. Therefore, the vacuum cleaner 100 can quickly switch the usage mode for cleaning. Moreover, since the handy cleaning member 90 can remain attached to the vacuum cleaner main body 1, cleaning can be performed while scraping out dust in the handy vacuum cleaner 100 with the handy cleaning member 90 attached. Furthermore, since there is no need to remove the handy cleaning member 90, there is no chance of it being lost.

FIG. 17 shows a side view of the vacuum cleaner 100 and the support stand 70.

The vacuum cleaner 100 is supported by the support stand 70 with the extension pipe 300 and the standard suction port 400 connected to the vacuum cleaner main body 1. Specifically, a substantially L-shaped hook 301 is provided at the distal end of the extension tube 300, with the distal end facing downward. When supporting the vacuum cleaner 100 on the support stand 70, the hook 301 is engaged with a locking part 72a provided on the stand part 72 of the support stand 70. Further, the standard suction port 400 is locked to the locking portion 71a1 on the mounting surface 71a. Thereby, the entire vacuum cleaner 100 can be supported on the support stand 70 with the vacuum cleaner main body 1 side on the upper side and the standard suction port 400 side on the lower side.

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

As shown in FIG. 1, the mounting surface 71a of the base portion 71 is formed to extend further forward than the extension tube 300. Thereby, in a state where the standard suction port 400 is connected to the extension tube 300, that is, in a state where the extension tube 300 and the standard suction port 400 are connected to the vacuum cleaner main body 1 (stick state), the standard suction port 400 can be supported on the mounting surface 71a. Therefore, the vacuum cleaner 100 can be stably supported on the support stand 70.

FIG. 18 shows a side view of a usage pattern when cleaning a floor surface Y with the vacuum cleaner 100 in a stick state. FIG. 16 shows a vacuum cleaner 100 with the handy cleaning member 90 attached, an extension pipe 300 and a standard suction port 400 connected to make it stick, and the vacuum cleaner 100 pushed out ahead of the user to clean the floor. This is a case of cleaning Y.

In this case, the user can clean the vacuum cleaner 100 while holding the second grip part 12a2 of the handle part 12 and moving the vacuum cleaner 100 back and forth. Although not shown, when cleaning the floor surface Y with the vacuum cleaner 100 positioned on the left and right sides of the user, the user grasps the first grip portion 12a1 of the handle portion 12. At the same time, the vacuum cleaner 100 can be moved back and forth. In this manner, when the user cleans the floor surface Y, the user can change the position of the handle portion 12 and clean the floor surface Y.

In conventional vacuum cleaners whose center of gravity is on the tip side when in the stick state (see Japanese Patent Application Laid-open No. 2016-137165), when the vacuum cleaner is used in a place higher than the floor Y, the user can Since it is necessary to lift the tip upward, there is an inconvenience in that it tends to put strain on the wrist.

FIG. 18 shows a side view of a usage pattern when cleaning a high place with the stick vacuum cleaner 100.

In this vacuum cleaner 100, as shown in FIG. 18, the fan motor 40 (see FIG. 8) and the storage battery 3, which are heavy items, are located close to the handle portion 12 (close to the user's hand), so the electric power is The center of gravity of the vacuum cleaner 100 is closer to the user's hand.

Thereby, 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 Y, such as a staircase K, it becomes easier to clean, and usability can be improved.

In addition, in FIG. 19, the case of cleaning the stairs K was explained as an example, but it is also effective when lifting the vacuum cleaner 100 to clean the panel of an indoor unit of an air conditioner.

In addition, when the vacuum cleaner 100 is used in a stick state, when removing dust remaining at the corner of the stairs K, the extension tube 300 and standard suction port 400 can be removed from the vacuum cleaner 100 to make it handy. Make it. In this case, since the handy cleaning member 90 remains attached to the vacuum cleaner 100, it is possible to immediately clean the corners of the stairs K to remove the dust remaining thereon, thereby suppressing the amount of dust left behind. .

Note that the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the embodiments described above are described in detail to explain the present invention in an easy-to-understand manner, and the present invention is not necessarily limited to having all the configurations described.
