Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vacuum cleaner used in a general household.
[0002]
[Prior art]
Conventionally, a vacuum cleaner has been configured as shown in FIG. Hereinafter, the configuration will be described.
[0003]
As shown in FIG. 54, the electric blower 501 is disposed in the cleaner main body 502, and has a dust collecting portion 504 in which a dust collecting bag 503 is built above the cleaner main body 501, and the dust collecting portion 504 The suction part 505 is connected by a hose 506. In FIG. 54, as indicated by an arrow, dust is sucked together with air from the bottom surface portion 507 of the suction portion 505 by the electric blower 501 and rises against the gravity inside the hose 506, and the dust is filtered by the dust collecting bag 503. , Captured inside the dust bag 503. The sucked air passes through the dust bag 503, passes through the inside of the electric blower 501, and is discharged to the outside through the exhaust port 508.
[0004]
Moreover, the vacuum cleaner which has the charging stand which built the rechargeable battery and also used as a stand is comprised as shown in FIG. The vacuum cleaner main body 509 accommodates a secondary battery and an electric blower (both not shown), and a suction tool 510 is tiltably attached to the lower portion of the vacuum cleaner main body 509. The charging stand 511 charges a secondary battery stored in the cleaner body 509. The charging stand 511 includes a placement portion 512 on which the suction tool 510 is placed, a power transformer for charging, and a charging terminal. And a box-like portion 513 provided with (not shown).
[0005]
And if the suction tool 510 is mounted on the mounting part 512 of the charging stand 511, the terminal provided in the cleaner body 509 and the terminal of the charging stand 511 are electrically connected, so that the secondary battery is charged. It is composed.
[0006]
Also, as shown in FIG. 56, by setting the cleaner body 514 with the secondary battery built in the charger 515, the circuit connected to the electric blower 516 in the cleaner body 514 is forcibly cut off. Some switches to a dedicated charging circuit.
[0007]
When the cleaner body 514 is set in the charger 515, the charging terminal 517a is deformed simultaneously with the deformation terminal 518a, and the deformation terminal 518a is separated from the fixed terminal 518c. By this operation, the electric blower 516 is closed regardless of whether the switch 519 is opened or closed, and becomes a circuit dedicated to charging.
[0008]
This is because, when charging is performed with the switch 519 turned on, the power consumption in the electric blower 516 exceeds the charging capacity of the charger 515, so that the charging cannot be performed substantially. Therefore, by switching the circuit, the battery can be reliably charged regardless of the state of the switch 519.
[0009]
[Problems to be solved by the invention]
However, since the electric blower 501 is disposed in the cleaner body 502, the weight and volume of the cleaner body 502 are large, the weight applied to the handle 118 during use is large, and the operability is not good. It was.
[0010]
Further, when the cleaner main body 502 is set substantially perpendicular to the floor surface and the cleaner main body 502 is rotated rearward, there is no obstacle behind the cleaner main body 502. When rotating forward, the lower part of the cleaner body 502 and the upper part of the suction part 505 hit and the rotation of the cleaner body 502 is suppressed. For this reason, the distance for reciprocating the vacuum cleaner main body 502 with the handle 118 is limited, and the floor area for reciprocating the vacuum cleaner main body 502 is limited, increasing the number of reciprocations and increasing the time for cleaning the floor surface and the like. It was becoming.
[0011]

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0016]
(Reference Example 1)
Reference Example 1 of the present invention will be described with reference to FIGS.
[0017]
As shown in FIGS. 1 to 3, the vacuum cleaner main body 1 includes a suction portion 2 on the front side and a main body portion 5 including a dust collection portion 3 and an electric blower 4 on the rear side. The handle 6 includes a handle 7 and is attached to a shaft support 8 that is rotatably provided on the main body 5. The battery 10 is a primary battery or a secondary battery for power supply, and is disposed between the main body portion 5 and the suction portion 2 and integrated with a heat shrink film.
[0018]
The dust collecting unit 3 includes a filter 11, is fitted to the mounting unit 12 of the main body unit 5, and is detachably mounted with a buckle (not shown), and has a substantially cylindrical configuration. As shown in FIG. 4, the dust collection portion 3 is formed with an intake port 14 having an intake packing 13 attached to the outer periphery thereof, and is pressed against the end surface of the intake passage 16 communicating with the intake portion 15 provided in the suction portion 2. is doing.
[0019]
The electric blower 4 is held by a support 17 made of an elastic body, and is fixed to the main body 5 with a screw (not shown) together with the motor case 18 as shown in FIG. Further, the shaft support portion 8 of the handle portion 6 is rotatably attached with the outer periphery of the motor case 18 as a bearing portion. Further, as shown in FIG. 7, the electric blower 4 is connected in parallel to the power supply battery 10 via a current fuse 19 and a power switch 20. The suction part 2, the dust collection part 3, the electric blower 4, the intake passage 16, and the battery 10 are arranged on a substantially flat surface in the cleaner body 1.
[0020]
In the above configuration, dust sucked together with the suction air of the electric blower 4 from the suction portion 2 passes through the intake passage 16 and is carried to the dust collection portion 3 and is captured by the filter 11. At this time, since the dust collecting unit 3 and the electric blower 4 are disposed on a substantially flat surface with the suction unit 2, the dust only needs to move on a substantially horizontal surface near the floor surface, and does not need to be lifted upward. Dust having a relatively large mass can be captured with small energy, and the battery 10 and the electric blower 4 can be made small and light.
[0021]
Further, since all the components are housed in the cleaner body 1 and the handle portion 6 is independently rotatable with the cleaner body 1, the weight of the cleaner body 1 does not act on the handle 7 during use. Therefore, the load during cleaning can be reduced.
[0022]
Next, as shown in FIG. 1 to FIG. 3, the dust collecting unit 3 and the electric blower 4 configured in the main body unit 5 provided behind the suction unit 2 have their axes HH in the longitudinal direction of the suction unit 2. The width L of the main body 5 is smaller than the width W of the suction portion 2.
[0023]
In the above configuration, the dust collection unit 3 and the electric blower 4 of the main body unit 5 are arranged in parallel with the longitudinal direction of the suction unit 2, so that the size in the front-rear direction can be reduced and made compact. There are few protrusions when placed on the wall when the stand is stowed, and the stowage can be improved. Further, since the width dimension L of the main body part 5 is smaller than the width dimension W of the suction part 2, the side surface of the main body part 5 does not hit the furniture or the like before the suction part 2 during cleaning, and the suction part 2 Since the dust can be captured by effectively using the entire width of the cleaning space, the cleaning efficiency can be improved.
[0024]
Next, as shown in FIGS. 1 and 5, the first traveling roller 21 is provided on the lower surface of the main body portion 5, and the battery 10 is disposed between the first traveling roller 21 and the suction portion 2. It is configured so that it can be removed by detaching the lid 22. Moreover, in FIG. 5, the suction part 2 and the main-body part 5 are comprised by the inclined plane 23 which substantially touches both upper surfaces.
[0025]
In the above configuration, the weight of the battery 10 acts in the direction of pressing the suction part 2 against the floor surface with the first traveling roller 21 as the center, and the gap between the suction part 2 and the floor surface can be stably secured, and the dust collection Efficiency can be increased. In addition, the inclined flat surface 23 can be smoothly inserted under furniture or the like during the cleaning, so that the catch can be reduced and the usability can be improved.
[0026]
Further, as shown in FIGS. 1 and 6, the suction part 2 is configured with an exhaust part 24 at an end opposite to the intake part 15 provided at one end. An exhaust passage 27 communicating with the exhaust part 24 through the discharge part 26 of the part 5 is configured. A brush body 30 in which a lip body 28 made of a bristle brush or a rubber blade or the like is attached to a shaft body 29 is rotatably attached to the inside of the suction portion 2 by a bearing 31 and can be driven to rotate by a motor 32 via a belt body 33. I am doing so. The brush body 30 constitutes a dust scooping body.
[0027]
Further, the lip body 28 is made of hair or rubber material that can be washed with water, and the shaft body 29 is also made of synthetic resin material that can be washed with water. The upper cover 34 can be detached from the cleaner body 1 and can be attached and detached together with the bearing 31. It has a configuration. A part of the outer periphery of the electric motor 32 is configured to face the exhaust passage 27. Further, as shown in FIG. 7, the electric motor 32 is also electrically connected to the battery 10 in parallel.
[0028]
In the above-described configuration, the exhaust from the electric blower 4 is discharged from the exhaust port 25 and the discharge unit 26 through the exhaust passage 27 to the floor surface from the exhaust unit 24 to raise dust on the floor surface. A circulation flow that flows into the suction portion 15 through the suction portion 2 is formed, and the movement of dust to the dust collection portion 3 can be facilitated, and the dust collection efficiency can be increased. Further, due to the synergistic action of the scraping by the rotation of the brush body 30 and the circulation flow, the dust collection efficiency is increased as compared with the case of only the scraping by the rotation of the brush body 30 and the case of only the circulation flow without the brush body 30. be able to.
[0029]
Furthermore, since the brush body 30 is configured so as to be washed with water, the brush body 30 can always be kept clean, and the brush body 30 can be quickly and completely dried by the exhaust circulation flow, so that a sanitary configuration can be achieved. Further, by applying exhaust to the electric motor 32, even if the output of the electric motor 32 is increased, the temperature rise of the winding portion and the sliding brush can be suppressed, and the durability can be improved.
[0030]
Next, as shown in FIG. 4, a scraping portion 35 is provided on the rear lower surface of the suction portion 2 so as to protrude forward from the rear end of the outer periphery of the brush body 30 over substantially the entire width region of the suction portion 2. A holding part 37 having a flat part behind the scraping part 35 and capable of temporarily holding dust is provided. As shown in FIGS. 3 and 5, the first traveling roller 21 is provided on the lower surface of the main body 5, and the second traveling roller 36 is disposed on both sides behind the suction portion 2.
[0031]
In the above configuration, since the scraping portion 35 is provided, the dust scraping portion for scooping up the dust scraped up by the rotation of the brush body 30 to the holding portion 37 is formed, so that the dust is transferred to the dust collecting portion 3. It becomes easy and dust collection efficiency can be improved. The front end of the suction portion 2 can be floated with respect to the floor surface by the second traveling roller 36, and the front lower end E of the suction portion 2 forms a gap with the floor surface over the entire area. It is possible to easily absorb the dust from the entire area of the wall, and to reduce the operation resistance such as bumping on the carpet, so that the dust collection efficiency is high and the usability can be improved.
[0032]
(Reference Example 2)
Next, Reference Example 2 will be described with reference to FIGS.
[0033]
As shown in FIGS. 8 to 10, the vacuum cleaner main body 101 has a dust collection chamber 102 for accumulating dust therein, and an electric blower 104 having a dust collection filter 113 and a suction fan 112 in the dust collection chamber 102. Provided. The brush body 106 scoops up dust from the floor surface, is supported by a bearing 116, and is driven by a motor 105 via a belt 114 and a pulley 115. The battery 118 drives the electric blower 104, the electric motor 105, and the like.
[0034]
An intake portion 108 communicating from the suction portion 117 to the dust collecting chamber 102 and an exhaust portion 107 that discharges the exhaust from the electric blower 104 to the suction portion 117 are provided, and an airflow circulating from the exhaust portion 107 to the intake portion 108 is generated. A part of the exhaust air 109 discharged from the electric blower 104 is circulated to the exhaust part 107 of the suction part 117, and a part of the exhaust air is discharged to other than the suction part 117. The air volume of the intake air 110 that circulates to 108 is 50 to 95% of the total exhaust volume from the electric blower 104.
[0035]
In the above configuration, when the electric blower 104 is driven, the inside of the dust collecting chamber 102 is brought into a negative pressure state. As shown in FIGS. 11 and 12, a part of the exhaust air 109 discharged from the electric blower 104 is struck to the floor surface from the exhaust part 107 communicating with the suction part 117 from the rear of the electric blower 104, and the rest. Is discharged to the outside from the exhaust port 120 that communicates with the suction portion 117 and the outside. Thereby, the dust 103 on the floor surface is blown off by the suction part 117 and is released from the floor surface.
[0036]
Further, the suction portion 117 is provided with a brush body 106 that is configured to be rotatable with the cleaner body 101 at both ends by bearings 116, and this brush body 106 transmits power from the electric motor 105 by a pulley 115 and a belt 114. And rotate. The brush body 106 rotates to scrape dust that has hidden behind the hairs on the floor such as a carpet.
[0037]
The dust 103 released from the floor surface by the brush body 106 and the exhaust air 109 rides on the airflow circulating from the air portion 107 to the air intake portion 108 and is carried from the air intake portion 108 to the inside of the dust collecting chamber 102 to collect the dust. Accumulated in the dust collection chamber 102 by the filter 113. As a result, even if the suction force of the electric blower 104 is weak, by blowing the exhaust air 109 onto the floor surface, the dust 103 can be lifted from the floor surface and the dust collection efficiency can be improved.
[0038]
In addition, it is possible to prevent the dust 103 from being scattered to the suction portion 117 due to the air volume and the air speed of the exhaust air 109 being struck against the floor surface. Furthermore, since the heat generated from the electric blower 104 can be radiated to the outside together with the exhaust that is released to other than the suction portion 117, it is possible to suppress an increase in the temperature of the vacuum cleaner.
[0039]
Since part of the exhaust is discharged to the outside and not all is circulated to the intake section 108, the temperature rise of the electric blower 104 and the like can be suppressed, and durability can be improved. In addition, on a floor surface such as a carpet having a long bristle foot, the brush body 106 scoops up the floor surface, so that the exhaust air 109 reaches the back of the bristle foot and can blow up dust in the deep part of the floor surface.
[0040]
(Reference Example 3)
Next, Reference Example 3 will be described with reference to FIGS. 13 and 14.
[0041]
As shown in the figure, the air volume control valve 119 can adjust the air volume circulating from the exhaust section 107 to the suction section 117, the air volume discharged to the exhaust port 120, or both. Other configurations are the same as those of the second reference example.
[0042]
In the above configuration, the air volume control valve 119 is configured to be rotatable, and the air volume of the exhaust air 109 struck against the floor surface from the exhaust unit 107 and / or the air volume discharged to the exhaust port 120, or both, Adjust optimally according to the amount of dust in the dust chamber. As a result, the amount of the exhaust air 9 struck against the floor surface and the amount of dust in the dust collection chamber can be reduced while suppressing the scattering of the dust generated due to the excessively high wind speed to the outside of the suction portion 117. Dust on the floor can be collected most efficiently.
[0043]
(Reference Example 4)
Next, Reference Example 4 will be described with reference to FIG.
[0044]
As shown in FIG. 15, the suction portion 117 is provided at one end of the suction portion 117, and the exhaust portion 107 is provided at the other end opposite to the suction portion 117, and the exhaust air 109 discharged from the exhaust portion 107 is in the longitudinal direction of the suction portion 117. It is configured to generate an airflow that passes substantially parallel to the floor surface and circulates to the intake section 108. Other configurations are the same as those in Reference Example 2 described above.
[0045]
In the above configuration, since the airflow circulating from the exhaust unit 107 to the intake unit 108 is generated substantially in parallel with the floor surface in the longitudinal direction of the suction unit 117, dust and air move on a substantially horizontal plane near the floor surface. It becomes difficult to be disturbed by gravity. Further, by blowing the exhaust air 109 onto the floor surface, dust can be raised from the floor surface, and the dust collection efficiency can be improved.
[0046]
In addition, since the airflow circulating from the exhaust part 107 to the intake part 108 passes through the entire floor surface below the opening of the suction part 117, the exhaust air 109 flows smoothly over the longest distance to the intake part 108. Thus, the dust collection effect can be improved over a wide area of the floor. Further, since the exhaust air 109 circulates to the intake portion 108 so that the exhaust does not leak to the outside of the suction portion 117, the dust below the suction portion 117 does not scatter to the outside of the suction portion 117 and is easy to use. Can be improved.
[0047]
In addition, as shown in FIG. 16, exhaust portions 107 are provided at both left and right ends of the suction portion 117, and an intake portion 108 is provided in the middle of the exhaust portions 107, thereby exhausting the two exhaust portions 107 to hit the floor surface. Both the winds 109 circulate to the inner intake section 108, the distance between the exhaust section 107 and the intake section 108 is reduced, and the dust moving distance is reduced, thereby improving the dust collection performance.
[0048]
Further, it is possible to suppress the exhaust air 109 from leaking from the suction portion 117 to the outside of the suction portion 117, and dust at the lower portion of the suction portion 117 is not scattered outside the suction portion 117, so that the usability can be improved.
[0049]
In addition, as shown in FIG. 17, the intake portions 108 are provided at both left and right ends of the suction portion 117, and the exhaust portion 107 is provided in the middle of the intake portions 108, so that the exhaust portion 107 at the center of the suction portion 117 is placed on the floor surface. The exhausted air 109 struck is divided into two parts and circulates to the intake parts 108 at both ends of the suction part 117. Thereby, the dust collection capability near the center part of the suction part 117 can be improved, and it becomes easy to operate a vacuum cleaner aiming at the dust on a floor surface.
[0050]
(Reference Example 5)
Next, Reference Example 5 will be described with reference to FIGS.
[0051]
As shown in FIGS. 18 and 19, the exhaust part 107 is provided in front of the suction part 117 over substantially the entire width of the suction part 117. The intake portion 108 is provided behind the suction portion 117, and the exhaust air 109 is configured to be diffused from the exhaust portion 107 in the width direction from the front of the suction portion 117 and hit against the floor surface. Other configurations are the same as those of the reference example 2 described above, and the same configurations are denoted by the same reference numerals and description thereof is omitted.
[0052]
In the above-described configuration, the dust on the floor surface of the entire suction portion 117 in the width direction is blown out evenly by the exhaust air 109 and is released from the floor surface. Thereby, the dust blowing effect by the exhaust air 109 is produced in a wide range, and the dust can be collected evenly over the wide floor surface.
[0053]
In addition, as shown in FIG. 20, the exhaust part 107 is provided behind the suction part 117 over substantially the entire width of the suction part 117, the intake part 108 is provided in front of the suction part 117, and the exhaust air 109 is supplied from the exhaust part 107. By being configured so that it is diffused in the width direction from behind the suction portion 117 and struck against the floor surface, the exhaust air 109 causes the dust on the entire floor surface in the width direction of the suction portion 117 to be blown out evenly from the floor surface. Liberate.
[0054]
At this time, as shown in FIG. 21, the bending direction of the carpet or the like due to the advancement of the suction portion 117 during the operation of the vacuum cleaner is the same as the direction in which the exhaust air 109 is blown. Exhaust air 109 is blown up to. As a result, the dust blowing effect by the exhaust air 109 is generated in a wide range, and it is possible to collect the dust on the floor surface in a wide range and improve the dust collecting ability.
[0055]
(Reference Example 6)
Next, Reference Example 6 will be described with reference to FIG.
[0056]
As shown in FIG. 22, the exhaust unit 107 sets the opening area to be smaller than the opening area of the intake unit 108, and the wind speed of the exhaust air 109 discharged from the exhaust unit 107 is the intake air 110 sucked into the intake unit 108. The speed is higher than the wind speed. Other configurations are the same as those in Reference Example 2 described above.
[0057]
In the above configuration, by reducing the opening area of the exhaust portion 107, the wind speed of the exhaust air 109 is increased, and the exhaust air 109 can be strongly blown to the floor surface by hitting it against the floor surface. Dust and the like lurking in the deep part of the floor such as a long carpet can be raised from the floor to improve the dust collection efficiency.
[0058]
Further, as shown in FIG. 23, the opening area of the exhaust part 107 is set larger than the opening area of the intake part 108, and the wind speed of the exhaust air 109 discharged from the exhaust part 107 is sucked into the intake part 108. By making the speed lower than the wind speed of the air, it is possible to prevent the dust from being sucked out to the outside of the suction portion 117, which is generated because the wind speed of the exhaust air 109 struck against the floor surface is too high.
[0059]
In addition, by making the wind speed of the exhaust air 109 released from the exhaust section 107 substantially the same as the wind speed of the intake air 110 sucked into the intake section 108, the exhaust air 109 is blown onto the floor surface and dust is blown from the floor surface. In addition to improving the dust collection efficiency, the wind speed of the airflow generated from the exhaust unit 107 to the intake unit 108 is stabilized, and dust released from the floor surface can be collected smoothly from the intake unit 108.
[0060]
Further, as shown in FIG. 24, an air volume control valve 119 is provided in the vicinity of the exhaust unit 107 and the intake unit 108 so as to be slidable to the left and right, and the opening areas of the exhaust unit 107 and the intake unit 108 are freely adjusted. For example, on the floor surface of a carpet or the like, for example, on the floor surface of a carpet or the like, the air volume regulating valve on the exhaust section 107 side is adjusted by adjusting the wind speed of the exhaust air 109 discharged from the air or the air speed of the intake air 110 sucked into the intake section 108 By narrowing 119 and opening the air volume control valve 119 on the intake section 108 side, the wind speed of the exhaust air 109 can be increased, so that dust behind the bristle can be raised and the dust collection performance can be improved. On the wooden floor, conversely, the air volume control valve 119 on the exhaust section 107 side is opened and the air volume control valve 119 on the intake section 108 side is throttled to suppress dust on the floor from being scattered around. Can do.
[0061]
Further, as shown in FIG. 25, a guide wall 111 for smoothly guiding the exhaust air 109 and the intake air 110 is provided in the vicinity of the exhaust unit 107 and the intake unit 108, thereby providing a guide provided in the vicinity of the exhaust unit 107. The wall 111 can guide the exhaust air 109 in the direction toward the intake portion 108, and the guide wall 111 provided in the vicinity of the intake portion 108 can guide the intake air 110 in the direction toward the intake portion 108. Flows smoothly to the intake section 108, the air flow in the suction section 117 is stabilized, and the dust released from the floor surface by the exhaust air 109 can be collected smoothly from the intake section 108.
[0062]
(Reference Example 7)
Next, Reference Example 7 will be described with reference to FIG.
[0063]
As shown in FIG. 26, a brush body (dust scooping body) 106 is configured to be rotatable or oscillating, and a belt-like dust scooping portion 106a is attached to the brush body 106 in a spiral manner to rotate the brush body 106. The direction of the airflow that flows along the twist of the belt-like dust scooping portion 106a generated by this and the direction of the airflow that flows from the exhaust portion 107 to the intake portion 108 is matched. Other configurations are the same as those in Reference Example 2 described above.
[0064]
In the above configuration, the dust on the floor raised by the exhaust air 109 from the exhaust unit 107 is aligned with the traveling direction of the air flow along the twist of the belt-like dust scooping unit 106a generated by the rotation of the brush body 106. Therefore, since the dust collides with the belt-shaped dust scraping portion 106a, the dust flow is not hindered and is carried to the intake portion 108. Thereby, the airflow in the suction part 117 and the flow of dust become smooth, and dust collection performance can be improved.

[0071]
In the above-described configuration, the substantially cylindrical handle arm body 227 can eliminate unevenness in design and can be reduced in size from the shape equivalent to the outer periphery 225 of the substantially cylindrical cleaner body 215. Furthermore, since the outer diameter of the rotating handle arm body 227 is the same as the outer diameter 225 of the cleaner body 215, even if a large impact is applied to the handle arm body 227, the handle arm body 227 can be prevented from being broken and the strength is improved. can do.
[0072]
When cleaning, when the cleaner body 215 is reciprocated by holding the handle 230 formed on the handle arm body 227, the reciprocation distance can be increased, and the number of reciprocations can be reduced to improve usability.
[0073]
As shown in FIG. 29, the handle arm body 227 is positioned substantially in the center in the longitudinal direction of the cleaner body 215, and the electric blower 218 is disposed inside the handle arm body 227. With this configuration, the handle arm body 227 is positioned substantially at the center of the cleaner body 215 when the handle arm body 227 is carried with the rod-like protrusion 228 from the handle arm body 227, so that the weight balance of the cleaner body 215 is balanced. It becomes better and easier to carry.
[0074]
Furthermore, useless space is not required for the arrangement of the dust collection chamber 216 and the electric blower 218 in the cleaner main body 215, and the entire cleaner main body 215 can be reduced in size and weight.
[0075]
Further, as shown in FIGS. 29 and 30, the outer periphery of the cover 231 that covers the outer periphery of the electric blower 218 is used as a support shaft 232, and the handle arm body 227 is slid on the support shaft 232. Further, a part of the cover 231 forms an outline of the cleaner body 215, and is locked by a dust collection chamber lid 223 and an upper outline 224 disposed at both ends of the cover 231. With this configuration, the turning structure of the handle arm body 227 can be configured with two parts, the handle arm body 227 and the cover 231, and can be easily formed without using complicated parts.
[0076]
Further, as shown in FIGS. 27 and 28, a male or female screw is formed at the distal end of a rod-like protrusion 228 from the handle arm body 227, a plurality of extension pipes 229 made of pipes and the like, and a grip 30 with grip. Each is detachable. With this configuration, as shown in FIG. 31, according to the user-friendly height, the number of extension tubes 229 used can be changed to adjust the hand height of the handle 230, improving usability. be able to. Furthermore, by removing each extension tube 229 and the handle 230, it can be stored in a small storage space.
[0077]
Further, as shown in FIG. 32, the rod-like protrusion 228 and the grip handle 230 are configured to be detachable with screws or the like, so that the grip handle 230 is connected to the protrusion 228, and the handle If it has 230 and it cleans, it can be used as a handy type cleaner, and since handle 230 has grip nature, it can be operated without a sense of incongruity.

[0079]
(Example 2)
Next, Example 2 will be described with reference to FIGS. 34 and 35. FIG.
[0080]
As shown in FIG. 34, the substantially cylindrical handle arm body 227 is configured to rotate along the same locus as the outer periphery 225 of the substantially cylindrical cleaner body 215, and the handle arm body 227 The handle arm body 227 is rotated largely in the front-rear direction, and the handle arm body 227 can be rotated until the rod-shaped protrusion 228 hits an obstacle. It is configured to rotate. Other configurations are the same as those of the first embodiment.
[0081]
In the above configuration, as shown in FIG. 34, when cleaning the bottom of a narrow table or the like, the length La of the extension pipe 229 can be used effectively, and the interior can be cleaned to the back. Moreover, it becomes possible to clean from either the front side or the rear side of the cleaner body 215 according to the convenience of the user.
[0082]
Further, as shown in FIG. 35, since the rotation direction of the conventional cleaner body is mainly backward rotation, the movement distance of the cleaner body is the length of the user's hand and the movement of the cleaner body. Although it is the sum of the distance L1, since the rotation of the cleaner main body 215 can be greatly rotated in the forward direction, the cleaner main body 215 can be moved to the distance L2, and the cleaner main body 215 is moved to the same distance. The cleaning floor area to be reciprocated increases, the number of times the cleaner body 215 is reciprocated decreases, and the time can be shortened.
[0083]
In addition, as shown in FIG. 36, when the convex portion 233 is formed at the lower rear side of the cleaner body 215 and the cleaner body 215 is tilted in the vertical direction with respect to the floor surface, the convex portion 233 and the cleaner body 215 When the outer periphery 225 is in contact with the floor surface and has a function as a heel rest 233a, the cleaner body 215 can be tilted vertically to be in a standing state, and when the cleaner body 215 is stored in a narrow place, The depth L3 of the storage space can be shortened by tilting the cleaner body 215 in a direction perpendicular to the floor surface and rotating the handle arm body 227 in the forward direction of the cleaner body 215. Can be improved.
[0084]
Example 3
Next, Example 3 will be described with reference to FIGS.
[0085]
As shown in FIGS. 37 and 38, a plate-like spring 235 fixed by a rib 234 is provided inside the handle arm body 227, and the approximate center of the spring 235 is the center of rotation 226 as shown in FIG. And projecting in a substantially arcuate shape 236.
[0086]
A plurality of bosses 238 each having a recess 237 formed in the cover 231 are arranged opposite to the substantially arcuate shape 236 of the spring 235. The spring 235 is fitted and locked in the recess 237 according to the position where the handle arm body 227 rotates.
[0087]
The spring force of the substantially circular arc shape 236 of the spring 235 fitted into the concave portion 237 and locked is such that each of the suction ports 219 is formed when the vacuum cleaner main body 215 is floated in the air by holding the bar-like protruding portion 228 or the like. When the force by which the air inlet 219 rotates naturally by the weight of the component is (F) and the force by which the handle arm 227 is rotated by the vacuum cleaner body 215 by holding the handle 230 is (F1), the spring The force is set to satisfy (F) ≦ (F1). Further, the spring force of the substantially circular arc shape 236 of the spring 235 fitted and locked in each recess 237 is set to be slightly larger than (F). Other configurations are the same as those of the first embodiment.
[0088]
In the above configuration, when the vacuum cleaner main body 215 is floated in the air with the handle 230, the spring 235 is urged to one of the plurality of recesses 237, and the rotation of the handle arm body 227 is suppressed. When carrying the vacuum cleaner main body 215 with 230, the handle arm body 227 is not easily rotated, the locked state of the vacuum cleaner main body 215 is maintained, and the carrying can be carried comfortably.
[0089]
Further, when the handle arm body 227 is rotated to the rear of the cleaner body 215 when it is desired to be in a cleaning state, the air inlet 219 can smoothly transition to the cleaning state without following the handle arm body 227.
[0090]
Also, as shown in FIGS. 37 and 39, the rod-shaped protrusion 228 from the handle arm body 227 is substantially perpendicular to the floor surface, and is substantially on the center line 239 of the cleaner body 215, and the spring 235 is substantially omitted. An arcuate shape 236 is disposed, and a plurality of concave portions 237 provided on the cover 231 are disposed. Protruding margins 240 are formed at both ends of the boss 238 in which the recess 237 is formed. When the front side of the cleaner body 215 of the protrusion allowance 240 is the first protrusion allowance 241 and, conversely, the rear side of the cleaner body 15 is the second protrusion allowance 242, the first protrusion allowance 241 on the front side. Is slightly larger outward than the second protrusion margin 242 on the rear side.
[0091]
With this configuration, when the handle arm body 227 is rotated, the substantially arcuate shape 236 of the spring 235 interlocking with the handle arm body 227 rides on the protrusion margin 240. Here, since the first projecting margin 241 on the front side projects slightly larger outward than the second projecting margin 242 on the rear side, the force that the substantially arcuate shape 236 of the spring 235 rides on the projecting margin 240 is large. Therefore, as shown in FIG. 41, the force (F2) for turning the handle arm body 227 rearward of the cleaner body 215 by the handle 230 is smaller than the force (F3) for turning forward.
[0092]
Therefore, when the normal vacuum cleaner main body 215 in which the extension tube 229 and the handle 230 are perpendicular to the floor surface is stored or stored, the standability in the standing state is improved, and the extension tube 229 and the handle 230 are easily tilted. It wo n’t fall.
[0093]
In addition, the operation of rotating the handle arm body 227 by holding the handle 230 often rotates backward of the cleaner body 215 when actually cleaning. However, even if the position changes in a position perpendicular to the floor surface, the handle 230 is rarely operated in a state perpendicular to the floor surface, and can be used without any problem in operation.
[0094]
Example 4
Next, Example 4 will be described with reference to FIG.
[0095]
As shown in FIG. 42, the limit switch 243 enters and cuts off the energization circuit to the electric blower 218, and is fixed to the cover 231 with a convex rib 244. Further, a contact rib 246 that presses the contact portion 245 of the limit switch 243 when the handle arm body 227 is rotated is formed inside the handle arm body 227. Other configurations are the same as those of the first embodiment.
[0096]
In the above configuration, by rotating the handle arm body 227, the contact rib 246 operates the contact portion 245 of the limit switch 243. Therefore, by turning the handle arm body 227, a switch for starting and stopping is operated. Without any operation, it is immediately cleaned and the usability can be improved.

The cleaner main body 301 is regulated at a predetermined position of the charger 307 by the connection between the terminal connection portion 305 and the terminal portion 309 and the fitting between the hole portion 306 and the convex portion 312.
[0102]
From both side surfaces of the box-shaped part 308, a guide 313 is extended forward, and when the cleaner body 301 is placed on the charger 307, the guide 313 has a terminal connection part 305, a terminal part 309, and a hole. The portion 306 and the convex portion 312 are guided so as to correspond to each other, and the relationship between the interval A of the guide 313 and the width B of the portion placed on the charger 307 of the cleaner body 301 is A ≧ B. Preferably, A is set slightly larger than B.
[0103]
An upper portion of the front surface of the box-shaped portion 308 forms an inclined surface 314, and the rear roller 316 of the cleaner main body 301 rolls on the inclined surface 314. A display lamp 315 for energization display is provided on the upper surface of the box upper portion 308.
[0104]
In the above-described configuration, the secondary battery 303 and the electric blower 304 are housed inside, the vacuum cleaner body 301 having the charging terminal connection portion 305, and the charger 307 provided separately from the vacuum cleaner body 301, and The charger 307 includes a box-shaped portion 308 that houses the power transformer 310 and a charging terminal portion 309 that protrudes forward from the box-shaped portion 308, thereby reducing the size of the charger 307 itself. can do.
[0105]
In particular, the charger 307 places the rear side of the cleaner body 301 on the plate-like portion 311, and the suction portion 301 a located in front of the cleaner body 301 is located in front of the plate-like portion 311, so the suction portion is also The size of the conventional charger placed is significantly reduced.
[0106]
Further, the charging terminal portion 309 protrudes from the side wall of the box-shaped portion 308 of the charger 307, and the charging terminal is placed in the charging terminal connection portion 305 provided at a portion other than the suction portion 301a of the cleaner body 301. By adopting a configuration in which the portion 309 is inserted, the overall outer dimension in a state where the cleaner main body 301 is set in the charger 307 can be reduced, and a place for storage can be avoided during charging and storage.
[0107]
In the case where a rotating brush is provided in the suction portion 301a, dust attached to the rotating brush may fall on the floor surface when the cleaner body 301 is set on the charger 307, but as described above, on the charger 307 Therefore, if the cleaner body 301 is removed from the charger 307 in order to start cleaning, the dust that has fallen can be easily sucked out.
[0108]
Further, a plate-like portion 311 on which a part of the cleaner main body 301 is placed is provided near the bottom of the front surface of the box-like portion 308 of the charger 307, and the plate-like portion 311 and the cleaner main body 301 opposite to the plate-like portion 311 are provided. By providing at least one pair of convex portions 312 and holes 306 that engage with each other on the lower surface, the cleaner main body 301 can be more securely fixed to the charger 307.
[0109]
In addition, a pair of guides 313 are provided from the vicinity of both end surfaces of the front surface of the box-shaped portion 308 of the charger 307, and the position of the rear portion of the cleaner body 301 is regulated between them. The main body 301 can be set more easily and reliably. In particular, when the cleaner main body 301 is set on the charger 307 with the grip portion on the upper end side of the handle 302, the action of the guide 313 can be performed smoothly and reliably, and the strength of the charger 307 as a whole is improved. can do.
[0110]
Moreover, by setting the front upper part of the box-shaped part 308 of the charger 307 as an inclined surface 314, the rear roller 316 rolls on the inclined surface 314, and the cleaner body 301 can be set more smoothly on the charger 307. it can.
[0111]
In this reference example, the surface of the charger 307 facing the cleaner main body 301 is an inclined surface constituted by a flat surface. However, an invitation shape such as a cylindrical surface having a large radius (both concave and convex) is acceptable. The same effect can be obtained with other similar shapes.
[0112]
Further, it is needless to say that the same effect can be obtained by making the surface opposite to the charger 307 on the cleaner body 301 side an inclined surface or a cylindrical surface, and further, the effect can be further enhanced by implementing both. Absent.
[0113]
Further, the charging terminal connecting portion 305 is provided on the outer peripheral portion of the electric motor 304 a of the electric blower 304, that is, the terminal connecting portion 305 is provided without projecting outside the cleaner main body 301.

Even when the rear portion of the cleaner body 301 interferes with the inclined surface 314 of the charger 307 or the front surface of the box-shaped portion 308, the resistance is reduced because the rear roller 316 contacts the inclined surface 314 or the box-shaped portion 308. The attachment / detachment work can be easily performed, and the use of a soft material for the roller can be expected to reduce the impact generated during the attachment / detachment and to prevent damage.
[0117]
(Reference Example 9)
Next, Reference Example 9 will be described with reference to FIGS.
[0118]
As shown in the drawing, the vacuum cleaner main body 401 holds an operation handle 402 having a length of about 1 m at an upper portion thereof so as to be rotatable. Inside the vacuum cleaner main body 401, a secondary battery 403 and an electric blower 404 driven by the secondary battery 403 are mounted. Further, a terminal connection portion 405 for charging and a hole portion 406 are provided on the rear lower surface of the cleaner body 401.
[0119]
A switch 417 is built in the cleaner main body 401. As the ring 402a coupled to the handle 402 rotates backward about the cylindrical shaft portion 401c of the cleaner main body 401, one of the rings 402a. The cam surface 402b provided in the section pushes the lever 417a of the switch 417 so that the switch 417 enters. That is, the cutting state and the entering state are switched with the inclined portion of the cam surface 402b as a boundary.
[0120]
The tilt angle of the handle 402 until the handle 402 in the cut state is switched from the upright state to the enter state is about 10 degrees, whereas the tilt angle in the actual use state is when the handle length is 1 m. Since it is at least around 30 degrees, the switch 717 is not cut off during use.
[0121]
The charger 407 includes a box-shaped portion 408 and a charging terminal portion 409 provided at the front portion thereof. A power transformer 410 for charging is housed near the terminal portion 409 in the box-shaped portion 408. An indicator lamp 415 for energization display is provided on the external surface of the charger 407.
[0122]
A plate-like portion 411 is formed at the lower front end of the box-like portion 408, and a convex portion (engaged portion) 412 is provided on the plate-like portion 411, and this convex portion 412 is connected to the terminal connection portion 405 of the cleaner body 401. In a state where the terminal portion 409 of the charger 407 is connected, the charger 407 is provided at a position to be fitted into the hole portion 406. The terminal connection part 405 is provided with a positive electrode connection terminal 405a and a negative electrode connection terminal 405b, and the terminal part 409 is provided with a positive electrode charge terminal 409a and a negative electrode charge terminal 409b. It has a simple structure.
[0123]
Further, when the handle 402 is at a position where the switch 417 can be turned off, a recess (engagement portion) 402c is provided on the outer peripheral surface of the ring 402a at the same position as the hole portion 406. When set to 407, the convex portion 412 passes through the hole portion 406 and then fits into the concave portion 402c. In addition, an inclined portion 412 a is provided at the tip of the convex portion 412. In addition, a display lamp 415 using a light emitting diode is provided on the top surface of the charger 407.
[0124]
In the above configuration, when the cleaner body 401 is set in the charger 407 when the handle 402 is at the position where the switch 417 is turned off, the convex portion 412 passes through the hole portion 406 and then fits into the concave portion 402c. In this state, the handle 402 does not rotate, and therefore the switch 417 is not turned on. On the contrary, in the state where the switch 417 is turned on, the handle 402 is rotated, so that the recess 402c is moved to a position different from the hole 406, and the cleaner body 401 is charged. The device 407 cannot be set in a normal state.
[0125]
Therefore, the positive electrode connecting terminal 405a and the positive electrode charging terminal 409a, the negative electrode connecting terminal 405b and the negative electrode charging terminal 409b are not in contact with each other when the switch 417 is turned on, and are contacted only when the switch 417 is turned off. The circuit on the charger 407 side and the cleaner body 401 side is connected.
[0126]
The concave portion 402c and the hole portion 406 are provided on the bottom surface of the vacuum cleaner body 401, and the opposing convex portion 412 protrudes upward from the charger 407. Can be fitted together.
[0127]
Moreover, since the hole 406 is provided in the non-movable part of the cleaner main body 401, the cleaner main body 401 is reliably positioned with respect to the charger 407. Since the inclined portion 412a is provided on the outer periphery of the tip portion of the convex portion 412, the inclined portion 412a invites the inlet of the concave portion 402c even if the hole portion 406 and the concave portion 402c on the bottom surface of the cleaner body 401 are slightly displaced. The concave portion 402c is moved to a normal position. The indicator lamp 415 provided on the external surface of the charger 407 is turned on only when the cleaner body 401 is set in a normal state with respect to the charger 407 and the terminal connection portion 405 and the terminal portion 409 come into contact with each other.
[0128]
As described above, a recess (engagement portion) 402c for engaging the projection (engaged portion) 412 provided in the charger 407 and setting the cleaner main body 401 to the charger 407 is provided. When the switch 417 moves in accordance with the operation of 402 and the recess 402c does not engage with the protrusion 412 in the on position of the switch 417, only when the switch 417 is mechanically disconnected, Since the charger 407 can be connected, the circuit configuration is simplified, and the product defect rate that occurs in connection with the connection is reduced. As a result, the battery can be charged more reliably while being inexpensive, and is easy to use. Can be improved.
[0129]
In addition, since the handle 402 is used as the operation portion of the switch 417, the cleaner main body 401 and the charger 407 can be connected only when the switch 417 is turned off more securely without adding another part, and is inexpensive. Thus, usability can be improved.
[0130]
In addition, when the concave portion (engagement portion) 402c is exposed from the bottom surface of the cleaner body 401, the fitting operation of the cleaner body 401 and the charger 407 is performed by the weight of the cleaner body 401. If they are combined, the cleaner main body 401 will not be detached from the charger 407 and can be charged more reliably unless the cleaner main body 401 is artificially lifted or even a large impact is applied.
[0131]
Further, since the convex portion (engaged portion) 412 provided on the charger 407 is structured to be engaged with the concave portion 402c through the hole 406 provided on the bottom surface of the cleaner body 401, the vacuum cleaner for the charger 407 is provided. Since the positioning of the main body 401 is not affected by the rotation of the handle 402 or the like, not only is the positional deviation difficult to occur, but the convex portion 412 is reliably guided to the normal position, so the terminal connecting portion 405 and the terminal The portion 409 is contacted more accurately, and more reliable charging can be performed.
[0132]
In addition, since the inclined portion 12a is provided at the tip of the convex portion 412 provided in the charger 407, the inlet of the concave portion 402c is invited even when the hole portion 406 and the concave portion 402c on the bottom surface of the cleaner body 401 are slightly shifted. However, since the concave portion 402c is moved to the proper position, the cleaner body 401 does not become insufficiently attached to the charger 407, and charging can be performed more reliably.
[0133]
Further, since either the charger 407 or the cleaner main body 401 is provided with a display lamp 415 that operates only when the cleaner main body 401 and the charger 407 are electrically connected, the charger 407 is provided. Therefore, it is possible to reduce charging errors caused by imperfectly setting the vacuum cleaner body 401.
[0134]
In this reference example, the display lamp 415 is used as the notification means. However, the display lamp 415 is not limited to visual means, and it is needless to say that any means such as auditory means by an electronic alarm can be used. .

【The invention's effect】
As described above, according to the present invention, the handle arm body has an intake port for sucking dust in the front and a handle arm body that rotates or slides at least a part of the outer periphery of the cleaner body at the rear. The diameter of the handle can be increased, the strength is improved, and the shape of the handle arm body can be slimmed in design.
[0136]
Further, in a vacuum cleaner body having an air suction port for sucking dust in the front and incorporating both a dust collection chamber and an electric blower in the rear, at least the outer periphery of the vacuum cleaner body with the approximate center of the vacuum cleaner body as a rotation center Since the handle arm body that pivots or slides a part is provided, the weight balance of the cleaner body can be improved and can be easily carried.
[0137]
In addition, since the handle arm body is disposed so as to be positioned substantially in the center in the longitudinal direction of the cleaner body, and the electric blower is disposed substantially inside the handle arm body, the weight balance of the cleaner body is improved. Can be easily carried around. Furthermore, the vacuum cleaner body can be miniaturized by effectively using spaces such as a dust collection chamber and an electric blower in the vacuum cleaner body.
