[Forms for implementing invention]

Hereinafter, a mode for implementing the present invention (hereinafter referred to as "embodiment") will be described in detail while referring to the appropriate drawings. Fig. 1 shows a perspective view of a state where the vacuum cleaner of this embodiment is housed in a support stand. As shown in Fig. 1, the vacuum cleaner 100 can be changed into various usage forms such as a hand-held state and an upright state to perform cleaning. The support stand 70 accommodating the vacuum cleaner 100 is configured to accommodate the vacuum cleaner 100 in an upright state where the extension pipe 300 (accessory) and the standard suction port 400 (accessory) are connected, and includes a base portion 71 and a bracket portion 72. In addition, the vacuum cleaner 100 can be used by connecting a small suction port (accessory), a broom-type suction port (accessory), an extension hose (accessory), etc., which are not shown. In addition, the standard suction port 400 is an electric brush type that rotates a brush by a motor.

Fig. 2 is an exploded view of the vacuum cleaner of this embodiment. The drawings below FIG. 2 appropriately show the front, rear, left, and right directions as seen from the cleaner body 1. As shown in FIG. 2, the cleaner 100 includes a cleaner body 1, a dust box 2 (dust collecting device), a battery 3, and an airtight keeping member 90.

The cleaner body 1 is configured to include a body portion 10, a motor case body portion 11, and a grip portion 12.

The main body 10 is formed with a connection port 10a (suction port) for connecting an extension tube 300, a standard suction port 400 (refer to FIG. 1), and the like. The connection port 10a is formed of the same resin as the main body 10, the motor case 11, the grip 12, and the like. In addition, the connection port 10a has a substantially circular opening and is formed toward the front. In addition, the connection port 10a is formed with the aforementioned extension tube 300, standard suction port 400, small suction port (not shown), broom type suction port (not shown), etc. (hereinafter, collectively referred to as accessories) that can be connected as accessories. Happening). The connection port 10a is provided with a terminal (not shown) electrically connected to the circuit board 50 (refer to FIG. 6), and when a motor-driven accessory such as a standard suction port 400 is connected, the brush is made by the electrically connected motor Rotate.

Moreover, the dust box 2 is detachably attached to the main body 10, and it is equipped with the introduction pipe 14 (refer FIG. 3) which sends in the air containing the dust inhaled from the connection port 10a to the dust box 2.

The motor case 11 contains an electric blower 40 (refer to FIG. 6) and a circuit board 50 (refer to FIG. 6). In addition, a circular suction port (not shown) is formed on the front surface of the motor case body 11 to suck in clean air after the dust case 2 has been dust collected.

The grip 12 is provided on the rear side of the main body 10 and has a grip 12a formed in a substantially L-shape. The grip portion 12a has a first grip portion 12a1 that linearly extends so as to gradually increase the rear side in the front-rear direction, and a second grip portion 12a2 that linearly extends substantially in the vertical direction. In addition, the grip portion 12a is a second grip portion 12a2 that extends substantially downward from the rear end of the first grip portion 12a1. The first holding portion 12a1 is located on the front side of the second holding portion 12a2. The second grip portion 12a2 is slightly inclined so that the upper part faces the front with respect to the vertical direction. Moreover, the 1st holding part 12a1 and the 2nd holding part 12a2 are substantially rod-shaped, and are continuously formed. In this way, since the first grip 12a1 is also linearly formed with respect to the second grip 12a2, the user can easily recognize the position of the hand. In addition, since the first holding portion 12a1 and the second holding portion 12a2 are bent and connected at an angle close to a right angle, when holding the first holding portion 12a1, the hand is not easily shifted to the side of the second holding portion 12a2 Conversely, when holding the second holding portion 12a2, the hand is not easily shifted to the side of the first holding portion 12a1. The first grip portion 12a1 extends in the front-rear direction so as to gradually increase in height from the rear side. Therefore, it becomes easy for a hand to reach into the gap 12c (refer to FIG. 6).

In addition, an operation button 12b is provided on the upper surface of the first grip 12a1 of the grip 12. The operation button 12b is composed of, for example, three buttons of "strong", "standard", and "cut".

On the upper part of the front end and the upper rear part of the main body 10 are provided release buttons 18a and 18b which are operated when accessories such as the extension pipe 300 are removed. The depressing operation of the release buttons 18a and 18b releases the lock of the main body 10 and the accessories, and the accessories can be removed from the main body 10. The mechanism of the release buttons 18a and 18b will be described later.

In addition, an airtight holding member 90 can be attached to the front end of the main body 10. The airtight holding member 90 has a substantially circular cylinder 91. The cylindrical body 91 has a ring-shaped elastic portion 91a formed of soft resin on the front end side. The cylindrical body 91 has a connection portion 91b formed of a material harder than the aforementioned elastic portion 91a on the base end side and can be connected to the main body portion 10. The cylinder 91 is constituted by integrally forming two different types of members of the elastic portion 91a and the connecting portion 91b. In addition, the elastic portion 91a is composed of an elastically deformable (flexible and deformable) material such as an elastic body. By attaching such an airtight holding member 90 to the connection port 10a of the cleaner body 1, the entire front end 90s of the airtight holding member 90 can be in close contact with the ground, and the attractive force can be increased compared to the case where there is no close contact. In addition, by forming the connecting portion 91b with a rigid one, the airtight maintaining member 90 can be installed in a stable state without falling off to the main body portion 10.

In addition, in the present embodiment, a case where the elastic portion 91a is formed of an elastic material such as an elastic body is taken as an example for description, but it is not limited to this. For example, it is also possible to form substantially the entire cylindrical body 91 with the same material as the connecting portion 91b, and to equip the front end of the cylindrical body 91 with short hairs that are electrostatically transplanted in a ring shape. Even if it is equipped with such an electrostatic flocking, like an elastic body, the front end of the airtight maintaining member 90 can be brought into close contact with the ground, and the attractive force can be increased.

A fitting groove 10b elongated in the longitudinal direction is formed on the outer surface of the connection port 10a of the main body 10. The fitting groove 10b is formed on each of the left and right sides. A projection part (not shown) that is engaged with the aforementioned fitting groove 10b and is locked is formed at the base end of the connection part 91b.

In addition, a light-emitting element may be provided in the upper portion of the connection port 10a in the main body 10.

The battery 3 is a device that supplies electric power to the motor 40a (see FIG. 6) of the electric blower 40 that generates attractive force, and is composed of a secondary battery such as lithium ion and nickel hydrogen. In addition, the battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and the main body 10 can be attached and detached by sliding the case 3a in the front-rear direction.

Fig. 3 is a side view of the cleaner 100 in the state of Fig. 2 viewed from the left. As shown in FIG. 3, the dust box 2 is of a cyclone type, and has a function of separating air containing dust sucked in from the introduction pipe 14 into dust and air, and collecting the dust. In addition, the dust box 2 has a substantially cylindrical accommodating portion 2a, and the accommodating portion is arranged in front of the motor case body 11 with the axial direction in the front-rear direction. In addition, on the upper surface (side surface) of the dust box 2 is formed a substantially rectangular inflow port 2b connected to the introduction pipe 14 (refer to FIG. 2). The air containing the dust flowing into the inflow port 2b becomes a swirling flow, and after the centrifugal force acts on the dust to separate the dust and the air in the dust box 2, the dust-separated air is discharged from the rear (back) of the dust box 2.

In addition, on the front surface of the dust box 2, a lid 2c that opens and closes when the dust accumulated in the dust box 2 is discarded is rotatably supported via a hinge portion 2d. In addition, a lid latch mechanism 2e for unlocking the lid 2c is provided on the upper portion of the lid 2c. In addition, the internal mechanism of the dust box 2 can be constructed 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, the vacuum cleaner 100 has the dust box 2 installed below the main body 10 and in front of the motor box body 11. At this time, if the dust box 2 is mounted on the cleaner body 1, the lid latch mechanism 2e is hidden on the cleaner body 1 side. This is when the lid latch mechanism 2e is installed on the opposite side (outer side), the lid latch mechanism 2e may be released during cleaning. However, if the lid latch mechanism 2e is hidden on the side of the cleaner body 1, malfunctions can be prevented. For example, when cleaning a sofa or under a bed in an upright state, the cleaner body 1 may be brought close to the floor level. At this time, when the cover latch mechanism 2e is installed on the front side, there is a possibility that the cover latch mechanism 2e may be released by contact with the ground. The positions of the lid latch mechanism 2e and the hinge portion 2d are not limited to this, and it does not matter if they are provided on the left and right with respect to the cleaner body 1.

In addition, in the dust box 2, the dust brush 2s (refer to FIGS. 2 and 3) is detachably installed. The dust brush 2s is arranged at a position where the dust box 2 is not easily visible from the outside when the dust box 2 is installed in the cleaner body 1. Therefore, it is not easy to fall off during operation, and there is no need to store the dust removing brush 2s and the vacuum cleaner 100 in a different place.

Fig. 5 is a plan view of the vacuum cleaner of this embodiment. As shown in FIG. 5, the connection part 91b of the airtight holding member 90 is formed with extension parts 91b1, 91b1 which extend rearward on both left and right sides. A concave portion 91b2 is formed between the extended portion 91b1 on the left and the extended portion 91b1 on the right in a plan view. The concave portion 91b2 is fitted to the tip portion 10d1 of the protrusion 10d formed on the upper surface of the tip of the main body portion 10. Thereby, positioning in the front-rear direction and the left-right direction of the airtight maintaining member 90 with respect to the connection port 10a (refer FIG. 2) is performed.

The introduction pipe 14 formed in the main body portion 10 once extends diagonally to the right and then extends downward and is formed, and is connected to the inflow port 2b (see FIG. 2) of the dust box 2. Thereby, a swirling flow can be generated in the receiving portion 2a of the dust box 2, and the separation of dust due to centrifugal force can be effectively performed.

Fig. 6 is a sectional view taken along the line VI-VI in Fig. 5. As shown in FIG. 6, an electric blower 40 is housed in the motor case 11 of the main body 10. The electric blower 40 is driven by a motor 40a. In addition, in the motor case body 11, a circuit board 50 (circuit board) for controlling the cleaner body 1 is housed above the electric blower 40.

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

In addition, the electric blower 40 and the circuit board 50 are located below the first grip 12a1 of the hand grip 12. Thereby, when the user grips the first grip 12a1 and performs an operation, the center of gravity of the vacuum cleaner 100 becomes near below the first grip 12a1. Therefore, when the front end of the cleaner 100 is used upward, the cleaner 100 can be held stably.

In addition, a gap 12c for inserting a hand is formed between the first holding portion 12a1 and the upper surface 11c of the motor case body portion 11. In addition, a gap 12d is formed between the second holding portion 12a2 and the back surface 11d of the motor case body portion 11.

In addition, the thickness T1 of the first grip 12a1 is formed thinly, and the thickness T2 of the second grip 12a2 is formed thicker than the thickness T1. That is, the first grip portion 12a1 is formed thin, and the second grip portion 12a2 is formed thick. In this way, when the second gripping portion 12a2 is held for cleaning, the thickness T2 of the second gripping portion 12a2 is increased, making it easier to hold it strongly, and the strength of the second gripping portion 12a2 can be improved.

The storage battery 3 may be composed of, for example, a lithium ion battery with high energy efficiency. In addition, the battery 3 is arranged below the second grip 12 a 2 of the hand grip 12. In this way, by arranging the battery 3 at the rear end of the vacuum cleaner 100, the center of gravity of the hand grip 12 is brought close to the second grip 12a2. Therefore, when the front end of the vacuum cleaner 100 is used upward, the operating feeling can be reduced. .

In the dust box 2, a filter 5 is accommodated at the rear end of the accommodating portion 2a in the axial direction. The filter screen 5 is formed by being folded into a pleated shape, which can increase the area of the filter screen and reduce the pressure loss caused by the filter screen 5.

In addition, the filter 5 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The HEPA filter refers to an air filter with a particle collection rate of 99.97% or more for particles with a particle diameter of 0.3 μm relative to the rated air volume, and an initial pressure loss of 245 Pa or less.

As shown in FIG. 6, the dust box 2, the motor 40a, and the battery 3 are arrange|positioned on the straight line of the longitudinal direction (front-rear direction) of the cleaner body 1. As shown in FIG. In particular, the dust box 2 and the motor 40a are arranged coaxially in the longitudinal direction (front-rear direction) of the cleaner 100. The installation of the motor 40a and the battery 3 requires a wide space. However, since the motor 40a and the battery 3 and the dust box 2 are arranged in a straight line, the vertical width of the vacuum cleaner 100 can be narrowed, and the vacuum cleaner 100 can be made compact.

In FIG. 6, the flow of air sucked into the cleaner 100 is indicated by the arrow mark F. The air sucked into the dust box 2 enters the electric blower 40. The air passes around the motor 40a to cool the motor 40a. In addition, a part of the air passing through the motor 40a flows in the battery 3 to cool the battery 3. The remaining part of the air passing around the motor 40a and the air passing through the battery 3 merge at the circuit board 50 to cool the circuit board 50, and thereafter, are excluded from the system of the cleaner 100. At this time, since the battery 3 is arranged directly behind the motor 40a, it is easy to allow cooling air to flow in the battery 3. Thereby, the battery 3 can be cooled efficiently.

A circuit board accommodating space 50a for accommodating the circuit board 50 is provided behind the introduction pipe 14 in the housing above the motor 40a. In order to generate a swirling flow inside the dust box 2 at the front part of the cleaner 100, the introduction pipe 14 must be formed and has a certain degree of thickness in the vertical direction. Therefore, even if the frame of the cleaner 100 has a slightly vertical thickness to form the circuit board accommodating space 50a at the rear, the overall thickness of the cleaner 100 in the vertical direction does not increase. Here, if the circuit board 50 is accommodated in the circuit board accommodating space 50a, there is no need to provide another space for accommodating the circuit board 50. Therefore, the increase in the vertical thickness of the cleaner 100 can be suppressed.

In addition, at this time, since the arrangement position of the circuit board 50 becomes higher, the wiring of the connection port 10a provided with the circuit board 50, the connection end to the accessories, and the operation button 12b can be shortened. Therefore, the manufacturing cost of the vacuum cleaner 100 can be reduced by shortening the wiring and improving the workability during manufacturing.

Figures 7 and 8 are both enlarged cross-sectional views around the release buttons 18a and 18b. Even if either of the release buttons 18a, 18b is pressed, the attachment of the aforementioned extension pipe 300, the standard suction port 400 and other accessories to the cleaner body 1 can be released. Fig. 7 shows a state where neither the release buttons 18a, 18b are pressed. In this state, first, when the release button 18a is pressed, the release button 18a and its base end 18a1 are inclined toward the lower front side. Thereby, the predetermined latch mechanism is released, and the accessories can be removed from the cleaner body 1.

On the other hand, as shown in FIG. 8, when the release button 18b is pressed, the release button 18a and its base end 18a1 are inclined toward the lower front side. A long shaft-shaped 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. The base end portion 18b1 of the release button 18b is inclined toward the lower front side, and the base end portion 18b1 pushes out one end of the shaft-shaped member 18c in the forward direction. In this way, the shaft-shaped member 18c moves in the forward direction, and its other end presses the base end portion 18a1 of the release button 18a, and the release button 18a and its base end portion 18a1 are inclined toward the lower front side. Thereby, as shown in FIG. 8, the predetermined latch mechanism is released, and the airtight holding member 90 can be removed from the cleaner body 1.

In addition to the release button 18a, the release button 18b is also provided. Therefore, the user of the cleaner 100 can remove the accessories from the cleaner body 1 by operating the release button 18b while holding the first grip 12a1.

Fig. 9 is a side view of the vacuum cleaner viewed from the right side. The lower rear end of the dust box 2 and the lower front end of the cleaner body 1 are provided with attachment and detachment mechanisms 2g and 19 for attaching and detaching the dust box 2 to the cleaner body 1. That is, when the dust box 2 is attached or detached from the cleaner body 1, the attachment/detachment mechanism 2g and the attachment/detachment mechanism 19 are connected by a predetermined mechanism. The attachment and detachment mechanisms 2g and 19 extend to the lowest part of the cleaner 100, and in particular, the lower end of the attachment and detachment mechanism 19 becomes the lowest part of the cleaner 100, and a foot 19a is provided under the attachment and detachment mechanism 19. In addition, a leg 3n is also provided at the lowermost end of the battery 3.

Taking the lower side of the vacuum cleaner 100 as the bottom, when placed on a horizontal plane F, there are cases where heavy parts such as the motor 40a and the battery 3 are located at the lower rear of the vacuum cleaner 100, and the vacuum cleaner 100 is supported by the feet 19a, 3h In the horizontal plane F. At this time, because the foot 19a is located at the bottom end of the vacuum cleaner 100, and the foot 19a is located in the middle of the longitudinal direction of the vacuum cleaner 100, the vacuum cleaner 100 placed on the horizontal plane F is as shown in FIG. 9 The front shown faces diagonally upward. Therefore, the front end part of the connection port 10a which becomes a suction port also faces diagonally upward. Therefore, the front end 90s of the airtight holding member 90 also faces the oblique upper side. This is because, in a state where the cleaner 100 is supported on the horizontal plane F, the dust remaining in the connection port 10a and the airtight maintaining member 90 is unlikely to fall to the outside.

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

Fig. 10 is a side view as viewed from the left side of the vacuum cleaner of this embodiment. Fig. 11 is a cross-sectional view taken along line XI-XI in Fig. 10. In the frame structure of the cleaner 100, the frame 20 covering the motor 40a and the circuit board 50 is a flame-retardant one-piece case. Since the motor 40a and the circuit board 50 are not covered with a two-layer or three-layer frame structure, the cleaner 100 can be made lighter.

Fig. 12 is a cross-sectional view taken along line XII-XII in Fig. 10. As shown in FIG. 12, the storage battery 3 is a battery pack, and five single cells (battery cells) 3h are arranged in a line up and down in the case 3a, and two in the left and right, and one in the center. In this way, if the axial direction of the single cell 3h is directed in the front-rear direction, the width of the battery 3 can be narrowed compared to the case where the axial direction of the single cell 3h is directed in the left-right direction.

In the case 3a, the single cells 3h are held in a state of being held by a holding member 3j made of synthetic resin and housed. The holding member 3j is configured to form a gap 3k between the upper cell 3h and the lower cell 3h.

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

Fig. 13 is a plan view of a state where accessories are connected to the cleaner. As shown in FIG. 13, the cleaner 100 is configured such that the extension pipe 300 can be connected with the airtight holding member 90 connected to the cleaner body 1. In this way, even if the airtight maintaining member 90 is connected to the cleaner body 1, the position of the connection port 10a of the connection extension pipe 300 does not change. Therefore, the total length L connecting the cleaner body 1 with the extension pipe 300 and the standard suction port 400 can be shortened. In this way, since the standard suction port 400 is located close to the side, the handling is improved and the ease of use can be improved.

In the vacuum cleaner 100 shown in FIG. 13, even from the upright state, the extension tube 300 connected to the standard suction port 400 is removed to be held in a hand-held state, and the airtight maintaining member 90 is also attached to the vacuum cleaner body 1. Therefore, it can be cleaned while increasing the attractive force.

In addition, in the embodiment of FIG. 13, although the case where the extension pipe 300 and the standard suction port 400 are connected to the cleaner 100 is described as an example, it is not limited to this embodiment. For example, the standard suction port 400 is directly connected to the connection port 10a, and it can be used as a vacuum cleaner 100 in a handheld state. Thereby, since the airtightness with the ground can be improved by the airtight maintaining member 90, the attractive force can be improved.

In this way, the vacuum cleaner 100 is capable of attaching and detaching various accessories (accessories) in the state where the airtight maintaining member 90 is attached to the vacuum cleaner body 1, and the use form of cleaning can be quickly switched to perform cleaning. In addition, since the airtight holding member 90 can be directly attached to the cleaner body 1, the vacuum cleaner 100 in the handheld state with the airtight holding member 90 attached can be cleaned while ensuring high suction.

Fig. 14 shows a perspective view of the support stand of the vacuum cleaner. In addition, the support stand 70 shown in FIG. 14 is the state which removed the cleaner 100 and all the accessories (accessories). As shown in FIG. 14, the support table 70 is composed of a base portion 71 and a bracket portion 72.

The base portion 71 has a substantially rectangular placement surface 71a on which the standard suction port 400 (refer to FIG. 1) is placed. The mounting surface 71a is provided with a locking portion 71a1 for locking the standard suction port 400 from sliding down toward the front side.

The bracket portion 72 extends vertically upward from the bracket portion support portion 71b provided behind the mounting surface 71a. An engaging portion 72a is provided at the upper front portion of the bracket portion supporting portion 71b.

Fig. 15 shows a side view of the cleaner and the support stand. As shown in FIG. 15, the cleaner 100 is supported by the support stand 70 in a state where the extension pipe 300 and the standard suction port 400 are connected to the cleaner body 1. Specifically, a substantially L-shaped hook 301 with the front end as the lower side is provided at the front end of the extension pipe 300. Then, the hook 301 is engaged with the engaging portion 72a (FIG. 14) of the bracket portion 72 provided on the support table 70. In addition, the standard suction port 400 is locked to the locking portion 71a1 on the mounting surface 71a. Thereby, with the cleaner body 1 side as the upper side and the standard suction port 400 side as the lower side, the entire cleaner 100 can be supported by the support table 70.

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

In addition, the mounting surface 71 a of the base portion 71 is formed to extend forward from the extension pipe 300. Thereby, in the state where the extension tube 300 is connected to the standard suction port 400, that is, in the state where the extension tube 300 and the standard suction port 400 are connected to the cleaner body 1 (stand state), the mounting surface 71a can support the standard suction port 400. Therefore, the cleaner 100 can be stably supported on the support stand 70.

Fig. 16 is a view of the usage form of the vacuum cleaner in the upright state when cleaning the floor. Fig. 16 shows a state where the extension pipe 300 and the standard suction port 400 are connected to the vacuum cleaner 100 (with the airtight holding member 90 installed) in an upright state, and the vacuum cleaner 100 is made to protrude further forward than the user to clean the floor. At this time, the user holds the second grip portion 12a2 of the hand grip portion 12, and moves the cleaner 100 back and forth while cleaning. Also, although not shown, when cleaning the floor with the vacuum cleaner 100 positioned on the left and right armpits of the user, the user can hold the vacuum cleaner 100 while holding the first grip 12a1 of the grip 12 Move forward and backward. In this way, when cleaning the ground, the user can change the position of the hand grip 12 to perform cleaning.

Fig. 17 is a view of the usage form of the vacuum cleaner in the upright state when cleaning high places. However, when making the vacuum cleaner with the center of gravity on the front side (refer to Japanese Patent Application Laid-Open No. 2016-137165) when it is made upright, when cleaning the vacuum cleaner higher than the ground, the user must lift the tip of the vacuum cleaner up , So it is easy to burden the wrist.

Here, in this embodiment, as shown in FIG. 17, the electric blower 40 (refer to FIG. 6) and the battery 3, which are the weight of the vacuum cleaner 100, are located close to the grip 12 (position close to the side). , The center of gravity G of the vacuum cleaner 100 is close to the user. Thereby, even if the vacuum cleaner 100 is placed in an upright state, when the vacuum cleaner 100 is used to sweep a place higher than the ground, it is easy to clean, and the ease of use can be improved. In FIG. 17, although the case of cleaning the stairs is taken as an example for description, it is also effective when the vacuum cleaner 100 is lifted to clean the panels of the indoor unit of the air conditioner.

In addition, when cleaning the vacuum cleaner 100 in an upright state, to remove the dust remaining at the corners (corners) of the steps, remove the extension tube 300 and the standard suction port 400 from the vacuum cleaner 100 to be held. At this time, since the airtight keeping member 90 is attached to the cleaner 100, it is possible to perform cleaning while increasing the suction force, and it is possible to prevent dust accumulation. In addition, the present invention is not limited to the above-mentioned embodiments, but includes various modifications. For example, the above-mentioned embodiment is a detailed description for easy understanding of the description of the present invention, and it is not limited to those who have all the structures described.
