The insertion portion 84a has an annular insertion tube insertion portion 84e, which is capable of inserting the insertion tube portion 74c, at a position radially outward of the driven shaft insertion portion 84d. Further, a shaft engaged portion 84f engageable with the shaft engaging portion 74d of the driven shaft 74b is provided inside the driven shaft insertion portion 84d. Therefore, in a state in which the cover member 84 is attached to the end portion of the cleaning element inner tube 82, the driven shaft 74b and the inner insertion tube portion 74c of the second support portion 74 are inserted into the driven shaft insertion portion 84d and the inner insertion tube insertion portion 84e, whereby the cover member 84 and the driven shaft 74b can be rotatably coupled.
The rotary cleaning tool 46 can be rotatably supported by the first support portion 72 by fitting the cleaning tool main body 80 over the cleaning tool inner tube 82 as indicated by the arrow in fig. 6, so as to be in contact with the inner tube flange portion 82a as shown in fig. 4 and 5, and by inserting the bearing 72a constituting the first support portion 72 inside the cleaning tool inner tube 82 at the end portion on the inner tube flange portion 82a side. The rotary cleaning tool 46 can be rotatably supported by the second support portion 74 as shown in fig. 4 and 5 by inserting the bearing 74a, the driven shaft 74b, and the inner insertion tube portion 74c of the second support portion 74 into the driven shaft insertion portion 84d and the inner insertion tube insertion portion 84e of the cover member 84 attached to the end portion of the cleaning tool inner tube 82 as shown by arrows in fig. 6.
The cleaning tool driving unit 48 applies a driving force to the rotary cleaning tool 46 to rotate the same. In the present embodiment, the cleaning element driving unit 48 is built in the rotary cleaning element 46. Specifically, as shown in fig. 6, the cleaning tool driving unit 48 is formed by attaching the driving device 48b to the attachment seat 48a provided on the first support portion 72 side. Specifically, the driving device 48b is mounted in the hollow mounting seat 48 a.
The cleaning element driving portion 48 is sized to be inserted into the rotary cleaning element 46 (cleaning element inner cylinder 82). The driving device 48b is formed by integrating a motor and a speed reducer. The driving device 48b has an output shaft 48c, and the output shaft 48c can output the rotational power of the motor in a state of being decelerated by the decelerator. The output shaft 48c is provided with a driving unit-side engaging portion 48d, and the driving unit-side engaging portion 48d is engageable with an inner cylinder-side engaging portion 86a provided in the cleaning tool inner cylinder 82. The driving unit side engaging portion 48d protrudes in a direction intersecting (substantially orthogonal in the present embodiment) the axial direction of the output shaft 48 c. The cleaning tool driving portion 48 is driven in a state in which the driving portion side engaging portion 48d is engaged with the inner cylinder side engaging portion 86a, and can rotate the rotary cleaning tool 46.
The dust removing portion 50 shown in fig. 10 is for removing dust adhering to the rotary cleaning tool 46. The dust removing portion 50 is provided at a boundary portion between the rotary cleaning tool arrangement portion 60 where the rotary cleaning tool 46 rotates and the second dust collecting portion 64. The dust removing portion 50 extends along the rotary cleaning tool 46. The dust removing portion 50 is provided at a position where it abuts against a cleaning member 80a provided on the surface of the rotary cleaning tool 46. The dust removing portion 50 may be, for example, a blade shape, but in the present embodiment, is formed in a comb-tooth shape. The dust removing portion 50 can efficiently scrape off dust from the surface of the rotary cleaning tool 46, and is provided in a posture suitable for scraping off dust toward the second dust collecting portion 64 side.
The power supply portion 52 is a terminal electrically connected to the cleaning tool driving portion 48 via a wire 67 disposed in the wire housing portion 66. The terminal constituting the power-on portion 52 is electrically connected to a terminal provided on the cleaner body 20 side by connecting the joint portion 44 to the suction tool connection portion 22b of the cleaner body 20. This allows the cleaner body 20 to supply electric power to the cleaner driving unit 48, thereby rotating the rotary cleaner 46.
Action of electric vacuum cleaner 10
The electric vacuum cleaner 10 is operable in a plurality of operation modes including a first cleaning mode and a second cleaning mode. In the present embodiment, the electric vacuum cleaner 10 can select the operation mode by performing the switching operation via the operation unit 28.
The first cleaning mode is an operation mode in which the cleaning tool driving unit 48 is driven in a state in which the driving of the electric blower 22 is stopped. In the first cleaning mode, the electric blower 22 is in a stopped state, and therefore, no attractive force is generated by the electric blower 22. On the other hand, in the first cleaning mode, the cleaning element driving unit 48 is driven, and therefore the rotary cleaning element 46 rotates, so that dust on the cleaning surface is cleaned. In the first cleaning mode, dust is collected in the second dust collection portion 64 by rotation of the rotary cleaning member 46. In the first cleaning mode, the suction force of the electric blower 22 is not effective, and therefore, the dust collected in the second dust collection unit 64 is accumulated in the second dust collection unit 64.
The second cleaning mode is an operation mode for driving the electric blower 22. In the second cleaning mode, the electric blower 22 is in a driven state, thereby generating an attractive force. When the dust collected by the operation in the first cleaning mode is accumulated in the second dust collection unit 64 before the operation in the second cleaning mode, the dust accumulated in the second dust collection unit 64 can be collected to the first dust collection unit 24 by the suction force of the electric blower 22 by starting the operation in the second cleaning mode. In the second cleaning mode, the cleaning tool driving unit 48 may be driven together with the electric blower 22. As a result, the rotary cleaning tool 46 is rotated by the driving of the cleaning tool driving unit 48, and therefore, the dust collected by the rotary cleaning tool 46 is collected by the suction force to the first dust collecting unit 24 via the second dust collecting unit 64. For example, the user can perform cleaning in the first cleaning mode at a timing when the user does not want to generate noise (during night or sleeping of the child), and perform cleaning in the second cleaning mode at other timings, and thus can perform cleaning according to circumstances.
Modification of the invention
The electric vacuum cleaner 10 is merely an example of the present invention, and may have the following configuration, for example.
The electric vacuum cleaner 10 described above can perform the mode switching operation by the operation unit 28, but the present invention is not limited to this, and a voice recognition unit that accepts an operation by voice recognition may be provided instead of the operation unit 28 or in addition to the operation unit 28. In the case of adopting such a configuration, the mode can be switched to the recognized mode on the condition that the voice recognition unit recognizes a voice indicating any one of the plurality of modes. In the case of such a configuration, the mode can be switched easily not only in a type of vacuum cleaner that is used such as the above-described vacuum cleaner 10 in which a user grips the vacuum cleaner by himself or herself, but also in a type of vacuum cleaner that is operated without touching the vacuum cleaner by the user, such as a so-called robot vacuum cleaner.
The electric vacuum cleaner 10 is exemplified by a configuration in which the electric blower 22 is stopped in the first cleaning mode and the electric blower 22 is driven in the second cleaning mode, but the present invention is not limited thereto. For example, a first driving mode for driving the electric blower 22 with a first parameter, a second driving mode for driving the electric blower 22 with a second parameter larger than the first parameter, and the like may be provided in place of the first cleaning mode and the second cleaning mode, or in addition to the first cleaning mode and the second cleaning mode. In the first and second drive modes, the cleaning element drive unit 48 may be driven together with the electric blower 22. The parameter here may be the rotation speed of the electric blower 22, a value indicating the suction force of the electric blower 22, or a value indicating the negative pressure acting on the suction port 62. The electric vacuum cleaner 10 can control the on/off of the electric blower 22 as well as the switching between the first cleaning mode and the second cleaning mode, and can change the suction force by adjusting the output of the electric blower 22 as in the first driving mode and the second driving mode. With such a configuration, the electric vacuum cleaner 10 can perform cleaning in which noise generated by driving the electric blower 22 is suppressed in the first driving mode in which the electric blower 22 is operated at the first parameter (for example, low rotation speed), while performing cleaning in which the attractive force of the electric blower 22 is sufficiently applied in the second driving mode in which the electric blower 22 is operated at the second parameter (for example, high rotation speed). For example, if the electric blower 22 is set to operate with the parameter of the dust reaching the second dust collection unit 64 as the first parameter in the first driving mode and the parameter of the dust reaching the first dust collection unit 24 as the second parameter in the second driving mode, the cleaning can be performed according to circumstances.
The electric vacuum cleaner 10 is illustrated in a state in which the dust receiving inlet 64a of the second dust collecting part 64 is always open, but the present invention is not limited thereto. For example, the vacuum cleaner 10 may be configured such that an intake valve body that can be opened and closed is provided at the intake port 64 a. By adopting such a configuration, the electric vacuum cleaner 10 can suppress leakage of dust collected in the second dust collection unit 64 from the second dust collection unit 64 by vibration or the like.
The electric vacuum cleaner 10 is illustrated as an electric vacuum cleaner in which the discharge port 64b for discharging dust to the first dust collecting portion 24 side in the second dust collecting portion 64 is always open, but the present invention is not limited to this. For example, the vacuum cleaner 10 may be configured such that an openable/closable outlet valve body is provided in the outlet 64 b. With this configuration, dust discharged from the second dust collection unit 64 toward the first dust collection unit 24 can be suppressed from returning into the second dust collection unit 64 by vibration or the like.
The electric vacuum cleaner 10 is an example of a vacuum cleaner having a rod-like appearance, but the present invention is not limited thereto, and may be, for example, a cylinder type vacuum cleaner (including a vacuum cleaner main body having a main body portion and a first dust collecting portion, a handle, and a suction tool 40 communicating with the vacuum cleaner main body via a hose, the handle and the suction tool 40 being connected via an extension tube), a so-called robot type vacuum cleaner, or the like. In the case where the cleaner body 20 and the suction tool 40 are not separate from each other as in the autonomous robot cleaner, the first dust collecting portion 24 and the second dust collecting portion 64 need not be provided in the cleaner body 20 and the suction tool 40 as in the electric cleaner 10, and the first dust collecting portion 24 and the second dust collecting portion 64 may be provided in the same housing or the like. In this case, the second dust collection portion 64 is also disposed between the rotary cleaning tool 46 and a communication portion having a discharge port 64b at an end portion thereof for discharging toward the first dust collection portion 24.
The electric vacuum cleaner 10 is a vacuum cleaner having no extension pipe connecting the cleaner body 20 and the suction tool 40, but the present invention is not limited thereto. The cleaner may be formed to have an extension pipe connecting the cleaner body 20 and the suction tool 40. The electric vacuum cleaner in this case may be configured to: the device is provided with: a cleaner main body 20 including a main body portion 20a and a first dust collection portion 24 for collecting dust, the main body portion 20a having an electric blower 22 for generating suction force; a suction member 40; a handle provided on one side of the main body 20a in the first direction; and an extension pipe connecting the connection portion of the main body portion 20a and the suction tool 40, the main body portion 20a having a connection portion at the other side of the first direction of the extension portion extending in the first direction, the extension portion and the first dust collection portion 24 being arranged in a second direction orthogonal to the first direction. The first dust collection unit 24 is configured to be detachable from the main body 20 a.
The electric vacuum cleaner 10 is configured such that the cleaning tool driving part 48 is disposed inside the rotary cleaning tool 46, but is not limited thereto. The cleaning tool driving unit 48 may be configured by connecting a driving source such as a motor provided outside the rotary cleaning tool 46 to the rotary cleaning tool 46 by a power transmission member such as an endless belt so as to be able to transmit power.
In the above-described electric vacuum cleaner 10, the second dust collection portion 64 is formed so that the width is substantially the same at any portion from the intake port 64a side toward the discharge port 64b side, but the present invention is not limited to this. For example, as shown in fig. 11, the second dust collection portion 64 may be formed so that the width along the axial direction of the rotary cleaning tool 48 decreases from the intake port 64a side toward the discharge port 64b side. With such a configuration, when the suction force of the electric blower 22 acts, the dust flowing into the second dust collection unit 64 can be smoothly sucked from the inlet 64a side toward the outlet 64b side.
The electric vacuum cleaner 10 according to the above embodiment and modification can exhibit the following effects, for example, by having the configurations (1-1) to (1-7).
(1-1) the electric vacuum cleaner 10 includes: an electric blower (electric blower 22) that generates an attractive force; a dust collection unit (dust collection unit 30) that collects dust; a suction port (suction port 62) for sucking dust; a rotary cleaning tool (rotary cleaning tool 46) that rotates by being driven by a cleaning tool driving section (cleaning tool driving section 48); and an operation unit (operation unit 28) that can be switched to any one of a plurality of modes, wherein the dust collection unit has a first dust collection unit (first dust collection unit 24) and a second dust collection unit (second dust collection unit 64), the second dust collection unit is disposed on the suction inlet side of the first dust collection unit in a path connecting the first dust collection unit and the suction inlet, the plurality of modes include a first cleaning mode and a second cleaning mode, the first cleaning mode is a mode in which the cleaning tool driving unit is driven in a state in which the driving of the electric blower is stopped, and the second cleaning mode is a mode in which the electric blower is driven.
The electric vacuum cleaner 10 can be used as follows: when the cleaning tool driving unit is driven in a state in which the driving of the electric blower is stopped by operating in the first cleaning mode, the rotary cleaning tool is rotated to perform cleaning without generating a driving sound of the electric blower. The dust collecting portion of the electric vacuum cleaner 10 further includes a second dust collecting portion disposed on the suction port side with respect to the first dust collecting portion, in addition to the first dust collecting portion. Therefore, when the electric vacuum cleaner 10 is operated in the first cleaning mode in which the electric blower does not generate attractive force, the dust collected by the rotation of the rotary cleaning tool can be collected in the second dust collecting portion.
On the other hand, the electric vacuum cleaner 10 can clean the air by the suction force of the electric blower by driving the electric blower in the second cleaning mode. The electric vacuum cleaner 10 further includes a first dust collection unit at a position separated from the second dust collection unit in a direction away from the suction port (suction direction). Therefore, the electric vacuum cleaner 10 can collect the dust collected in the second dust collection unit by the operation in the first cleaning mode to the first dust collection unit by the suction force of the electric blower.
As described above, the dust collection unit of the electric vacuum cleaner 10 includes the first dust collection unit and the second dust collection unit, and the electric vacuum cleaner 10 can operate in a plurality of modes including the first cleaning mode and the second cleaning mode. Thus, the electric vacuum cleaner 10 can flexibly use the cleaning by the suction force of the electric blower and the cleaning by the rotation of the rotating brush.
(1-2) the electric vacuum cleaner 10 is preferably characterized by comprising a sound recognition unit for recognizing a sound instead of the operation unit, or comprising both the operation unit and the sound recognition unit, and switching to the recognized mode on the condition that the sound recognition unit recognizes a sound indicating any one of the plurality of modes.
According to this configuration, not only when the electric vacuum cleaner 10 is formed as a type of vacuum cleaner that is used such that the user grips the vacuum cleaner in his/her hand or the like as in the above-described embodiment, but also when the vacuum cleaner is formed as a type of vacuum cleaner that is operated without the user touching the vacuum cleaner (autonomous walking), for example, as in a so-called robot vacuum cleaner, the mode can be easily switched.
(1-3) the electric vacuum cleaner 10 is preferably characterized by comprising a suction tool main body (suction tool main body 42) rotatably supporting the rotary cleaning tool, wherein the second dust collecting part forms a part of the suction tool main body, and wherein the part of the second dust collecting part forming the suction tool main body has transparency.
With such a configuration, the electric vacuum cleaner 10 can visually confirm dust collected in the second dust collection unit from the transparent portion of the second dust collection unit. Thus, the electric vacuum cleaner 10 can be used in a manner that confirms the cleaning result of the rotary cleaning tool or that cleans the second dust collecting part while confirming the dust accumulation.
Further, the electric vacuum cleaner 10 may be configured such that the second dust collection portion is not transparent as a whole and the inside cannot be visually confirmed. The electric vacuum cleaner 10 having this structure cannot visually confirm dust accumulated in the second dust collection unit, but can improve the appearance of the second dust collection unit compared to a case where the inside of the second dust collection unit can be seen from the other side.
(1-4) the electric vacuum cleaner 10 is preferably characterized by having a suction body rotatably supporting the rotary cleaning member, and the second dust collecting portion is detachably provided to the suction body.
With such a configuration, the electric vacuum cleaner 10 can easily and appropriately remove the second dust collection unit, discard dust collected in the second dust collection unit, and perform maintenance such as cleaning the second dust collection unit.
Further, the electric vacuum cleaner 10 may be formed such that the second dust collection portion cannot be removed from the suction body. In the case of such a configuration, the electric vacuum cleaner 10 cannot be used for maintenance or the like by removing the second dust collecting portion, but on the other hand, it is possible to suppress problems such as use in a state where the second dust collecting portion is accidentally detached from the suction tool body.
(1-5) the electric vacuum cleaner 10 is preferably characterized by comprising a dust removing portion (dust removing portion 50) for removing dust adhering to the rotary cleaning tool.
The electric vacuum cleaner 10 thus configured can remove dust adhering to the rotary cleaning tool as the rotary cleaning tool cleans the dust by the dust removing section. Therefore, the electric vacuum cleaner 10 provided with the dust removing portion can clean by the rotary cleaning tool while maintaining the rotary cleaning tool in a cleaning state. In addition, dust adhering to the rotary cleaning tool can be easily erased and accumulated in the second dust collection part.
Further, the electric vacuum cleaner 10 may not include the dust removing portion, for example, in the case where the electric vacuum cleaner includes another structure for keeping the rotary cleaning tool clean or the dust does not need to be positively removed from the rotary cleaning tool. Accordingly, the structure of the electric vacuum cleaner 10 is simplified in response to the absence of the dust removing portion.
(1-6) the electric vacuum cleaner 10 is preferably characterized by having a rotary cleaning tool arrangement portion (rotary cleaning tool arrangement portion 60) in which the rotary cleaning tool is arranged, and the second dust collection portion communicates with the rotary cleaning tool arrangement portion.
The electric vacuum cleaner 10 having this structure can smoothly guide and collect dust entering the rotary cleaning tool arrangement portion in accordance with the rotation of the rotary cleaning tool to the second dust collection portion.
(1-7) the electric vacuum cleaner 10 is preferably characterized in that the electric blower and the cleaning element driving section are driven in the second cleaning mode.
Here, the dust box of the dust collector disclosed in patent document 1 (japanese unexamined patent publication No. 53-134769) is provided in the main body together with the rotary brush and the motor, and does not have an electric blower, so that noise during cleaning can be suppressed because sound generated by driving is not generated. However, this conventional vacuum cleaner has a problem that it is difficult to take dust attached to a carpet or a carpet into the main body, for example, because the suction of the electric blower is not utilized.
Accordingly, an object of the present invention is to realize a vacuum cleaner capable of cleaning with noise generated by driving an electric blower suppressed.
In order to achieve this object, the electric vacuum cleaner 10 according to the above embodiment and modification adopts the configurations (2-1) to (2-3). This enables the electric vacuum cleaner 10 to obtain the following effects.
(2-1) the electric vacuum cleaner 10 is characterized by comprising: an electric blower (electric blower 22) that generates an attractive force; a dust collection unit (dust collection unit 30) that collects dust; a suction port (suction port 62) for sucking dust; and an operation unit (operation unit 28) that can be switched to any one of a plurality of modes, wherein the dust collection unit has a first dust collection unit (first dust collection unit 24) and a second dust collection unit (second dust collection unit 64), the second dust collection unit is disposed on the suction port side of the first dust collection unit in a path connecting the first dust collection unit and the suction port, the plurality of modes include a first drive mode and a second drive mode, the first drive mode is a mode in which the electric blower is driven with a first parameter, and the second drive mode is a mode in which the electric blower is driven with a second parameter that is greater than the first parameter.
The electric vacuum cleaner 10 having this configuration is capable of performing cleaning in which noise generated by driving the electric blower is suppressed in the first driving mode in which the electric blower is operated at the first parameter, and is capable of performing cleaning in a state in which the attractive force of the electric blower is sufficiently applied in the second driving mode in which the electric blower is operated at the second parameter. Therefore, cleaning can be performed in which noise generated by driving the electric blower is suppressed.
(2-2) the electric vacuum cleaner 10 is preferably characterized in that the second dust collection part has: an intake port (intake port 64 a) for receiving dust sucked from the suction port; and an intake valve body provided in the intake so as to be openable and closable.
The electric vacuum cleaner 10 thus constructed can suppress leakage of dust collected in the second dust collection unit from the second dust collection unit by vibration or the like.
In the electric vacuum cleaner 10, the intake valve body may not be provided at the intake port of the second dust collection unit. The electric vacuum cleaner 10 having this configuration is simplified in configuration because the intake valve is not present, and an increase in suction resistance due to the provision of the intake valve can be suppressed.
(2-3) the electric vacuum cleaner 10 is preferably characterized in that the second dust collection part has: a discharge port (discharge port 64 b) for discharging dust to the first dust collection unit side; and a discharge port valve body provided in the discharge port so as to be openable and closable.
The electric vacuum cleaner 10 thus configured can suppress dust attracted to the first dust collection unit side by vibration or the like from being affected by vibration or the like and returning to the second dust collection unit side.
Further, the electric vacuum cleaner 10 may not be provided with the discharge port valve body at the discharge port of the second dust collection unit. The electric vacuum cleaner 10 having this configuration is simplified in configuration because the discharge port valve is not present, and an increase in suction resistance due to the provision of the discharge port valve can be suppressed.
Here, the dust box of the dust collector disclosed in patent document 1 (japanese unexamined patent publication No. 53-134769) is provided in the main body together with the rotary brush and the motor, and does not have an electric blower, so that noise during cleaning can be suppressed because sound generated by driving is not generated. However, this conventional dust collector has a problem that the size of the dust box is increased to increase the amount of dust stored therein, and the size of the dust box is reduced to reduce the size of the whole body, which is a problem.
Accordingly, an object of the present invention is to improve the amount of dust stored and to reduce the size of an electric vacuum cleaner.
In order to achieve this object, the electric vacuum cleaner 10 according to the above embodiment and modification adopts the configurations (3-1) to (3-4). This enables the electric vacuum cleaner 10 to obtain the following effects.
(3-1) the electric vacuum cleaner 10 is characterized by comprising: a cleaner main body (cleaner main body 20) provided with a main body portion (main body portion 20 a) and a first dust collection portion (first dust collection portion 24), wherein the main body portion (main body portion 20 a) is provided with an electric blower (electric blower 22) generating attractive force, and the first dust collection portion (first dust collection portion 24) collects dust; and a suction member (suction member 40) having a suction port (suction port 62) for sucking dust and a second dust collection portion (second dust collection portion 64) for collecting dust.
In the electric vacuum cleaner 10, in addition to the first dust collection unit of the cleaner main body, the second dust collection unit provided in the suction tool can be used for collecting dust, and the amount of dust collected increases accordingly. Further, since the second dust collection portion of the electric vacuum cleaner 10 is provided to the suction tool, the first dust collection portion is not increased in size to ensure a large capacity. Therefore, the electric vacuum cleaner 10 can sufficiently secure the amount of dust stored therein and can be miniaturized.
(3-2) the electric vacuum cleaner 10 is preferably: the electric blower is provided with a mode switching unit capable of switching to a plurality of modes having different rotational speeds of the electric blower, wherein the modes include a first drive mode and a second drive mode, the first drive mode is a mode for driving the electric blower at a first rotational speed, and the second drive mode is a mode for driving the electric blower at a second rotational speed greater than the first rotational speed.
In the first drive mode, the electric vacuum cleaner 10 can operate the electric blower at a first rotation speed that is low in rotation speed to perform cleaning. Thus, in the first driving mode, the electric vacuum cleaner 10 can perform cleaning with noise generated by driving the electric blower suppressed. On the other hand, in the second drive mode in which the electric blower is operated at the second rotation speed of the high rotation speed, the electric vacuum cleaner 10 can perform cleaning in a state in which the attractive force of the electric blower is sufficiently acted. Therefore, the electric vacuum cleaner 10 can perform cleaning in which noise generated by driving the electric blower is suppressed.
In the case of the above configuration, the electric vacuum cleaner 10 is operated in the first drive mode and the second drive mode in association with the operation of the electric blower, but the present invention is not limited thereto. Specifically, as in the above embodiment, the electric vacuum cleaner 10 may be configured to perform the first mode operation and the second mode operation in place of or in addition to the first mode operation and the second mode operation, the first mode operation being a mode in which the rotary cleaning tool is rotated in a state in which the electric blower is stopped, and the second mode operation being a mode in which the electric blower is driven.
(3-3) the electric vacuum cleaner 10 is preferably characterized in that the second dust collection part has: an intake port (intake port 64 a) for receiving dust sucked from the suction port; and an intake valve body provided in the intake so as to be openable and closable.
The electric vacuum cleaner 10 thus constructed can suppress leakage of dust collected in the second dust collection unit from the second dust collection unit by vibration or the like.
In the electric vacuum cleaner 10, the intake valve body may not be provided at the intake port of the second dust collection unit. The electric vacuum cleaner 10 having this configuration is simplified in configuration because the intake valve is not present, and an increase in suction resistance due to the provision of the intake valve can be suppressed.
(3-4) the electric vacuum cleaner 10 is preferably characterized in that the second dust collection part has: a discharge port (discharge port 64 b) for discharging dust to the first dust collection unit side; and a discharge port valve body provided in the discharge port so as to be openable and closable.
The electric vacuum cleaner 10 thus configured can suppress dust attracted to the first dust collection unit side by vibration or the like from being affected by vibration or the like and returning to the second dust collection unit side.
Here, when the dust box of the dust collector disclosed in patent document 1 (japanese unexamined patent publication No. 53-134769) is provided in the main body together with the rotary brush and the motor, dust may adhere to wiring connected to devices such as the motor, causing unexpected trouble or the like, or the wiring may interfere with the rotation of the rotary brush. Therefore, in a dust collector such as patent document 1, it is required to adopt a configuration in which wiring is disposed at a position where dust is not attached and separated from a rotary brush.
Accordingly, an object of the present invention is to provide a wiring capable of preventing dust from adhering to the wiring and preventing the rotation of the cleaning tool from being hindered.
In order to achieve this object, the electric vacuum cleaner 10 according to the above embodiment and modification adopts the configuration of (4). This enables the electric vacuum cleaner 10 to obtain the following effects.
(4) The electric vacuum cleaner 10 is characterized by comprising: a cleaner main body (cleaner main body 20) provided with a main body portion (main body portion 20 a) and a first dust collection portion (first dust collection portion 24), wherein the main body portion (main body portion 20 a) is provided with an electric blower (electric blower 22) generating attractive force, and the first dust collection portion (first dust collection portion 24) collects dust; and a suction member (suction member 40) having a suction port (suction port 62) for sucking dust, the suction member having: a cleaning tool drive unit (cleaning tool drive unit 48) that rotates the rotary cleaning tool (rotary cleaning tool 46); a second dust collection unit (second dust collection unit 64) that collects dust; a current-carrying portion (current-carrying portion 52) electrically connected to the cleaning tool driving portion via a wiring (wiring 67); a wiring housing (wiring housing 66) for housing the wiring; and a partition wall (partition wall 68) that separates the wiring housing portion from the second dust collection portion.
The electric vacuum cleaner 10 is provided with a second dust collecting part at the suction member separately from the first dust collecting part of the cleaner main body. The suction tool further includes a wiring housing portion partitioned from the second dust collecting portion by a partition wall, and wiring for connecting the cleaning tool driving portion and the current-carrying portion is disposed in the wiring housing portion. Since the electric vacuum cleaner 10 has such a configuration, the wiring can be disposed so as not to interfere with the driving of the rotary cleaning tool while suppressing adhesion of dust collected in the second dust collecting part to the wiring.
The present invention is not limited to the configuration described in the above embodiment, and design changes and the like can be appropriately performed within a range not departing from the technical scope of the present invention. The constituent elements of the above embodiments and modifications can be arbitrarily selected and combined. Any component of each embodiment or modification may be combined with any component described in the technical means, the specific embodiment, or the like for solving the problem, or any component described in the technical means, the specific embodiment, or the like for solving the problem. Regarding these, it is intended that patent rights be acquired in the present application or in a divisional application based on the present application, or the like.
