Fig. 6 is an operation schematic diagram of a lock mechanism unit of a dust collector according to a third embodiment, where (a) is a locked state and (B) is an unlocked state. In fig. 6(a) and (B), the same elements as those in fig. 4(a) and (B) are denoted by the same reference numerals.
The electric vacuum cleaner of the third embodiment has the same configuration as the first embodiment, except that the lock mechanism 212d of the dust collection device 212 is different from that of the first embodiment. Hereinafter, differences between the third embodiment and the first embodiment will be mainly described.
As shown in fig. 6(a) and (B), in the lock mechanism portion 212d of the third embodiment, a circular plate-shaped operating knob 212da is provided on the lid portion 212B so as to be rotatable about a shaft 212dx that is substantially perpendicular to the first linear axis a.
The housing recess 212bf of the cover 212b is formed in a substantially hemispherical shape.
The operation handle 212da is provided with a folded-sheet-shaped finger-digging piece portion 212dy which is easy to grasp the operation handle 212da at one end in a direction orthogonal to the axial center direction of the shaft 212dx, and is also provided with a notched portion 212dz at the other end opposite to the finger-digging piece portion 212 dy. When the operation handle 212da is rotated about the axis 212dx, the end portions of the finger piece portions 212dy and the notched portions 212dz are bent so as not to contact the cover portion 212 b.
Further, a projection 212bz is provided at a part of an opening edge of the housing recess 212bf of the cover portion 212b, and the projection 212bz abuts against the notch 212dz of the operation knob 212 da.
As shown in fig. 6(a), the operating knob 212da is disposed in substantially the same one surface as the upper outer surface 212dd of the operating knob 212da and the upper surface 212bg of the lid portion 212b in the closed state of the lock mechanism portion 212 d. At this time, the finger portion 212dy of the operation handle 212da is accommodated in the accommodation recess 212bf, and the notch portion 212dz abuts against the projection portion 212bz to define the rotational direction about the axis 212dx of the operation handle 212 da. That is, even if the finger piece portion 212dy side of the upper outer surface 212dd of the operation panel 212da is pressed, the operation knob 212da does not rotate.
The movement direction conversion unit of the lock mechanism 212d includes a first moving member 212g movable in a first linear direction a substantially perpendicular to the axial direction of the shaft 212dx, a second moving member 212h movable in a second linear direction B substantially perpendicular to the first linear direction a, and a biasing member 212i, and the locking convex portion 12db is coupled to the second moving member 212 h. The first moving member 212g, the second moving member 212h, and the urging member 212i are supported by a rib structure in the cover portion 212 b.
The first moving member 212g has a first inclined surface 212ga and a second inclined surface 212gb, and the first inclined surface 212ga is slidably connected to an operation knob 212da that rotates about a shaft 212 dx; the second inclined surface 212gb is provided on the opposite side of the first inclined surface 212ga in the first straight direction a.
The second moving member 212h has a third inclined surface 212ha slidably connected to the second inclined surface 212gb of the first moving member 212g moving in the first linear direction a, and a hole 212hb through which the lower end of the second inclined surface 212gb of the first moving member 212g is inserted.
The biasing member 212i is a compression coil spring that biases the second moving member 212h in a direction in which the third inclined surface 212ha of the second moving member 212h presses the second inclined surface 212gb side of the first moving member 212 g.
In the lock mechanism portion 212d having such a configuration, in the locked state shown in fig. 3 and 6(a), the second moving member 212h urged by the urging member 212i moves toward the locking convex portion 12db in the second linear direction B.
At this time, since the operation handle 212da of the dust collection device 212 is received in the receiving recess 212bf of the cover 212b, the upper outer surface 212dd of the operation panel 212da and the upper surface 212bg of the cover 212b are arranged in a substantially flat state on substantially the same one surface.
When the locked state of the lock mechanism portion 212d is released, the operation knob 212da is rotated about the shaft 212dx by pressing the upper outer surface 212dd on the projection portion 212bz side of the operation knob 212 da. As a result, as shown in fig. 6 (B), the end portion of the operation handle 212da on the notched portion 212dz side moves toward the bottom portion of the housing recess 212bf, and the end portion of the operation handle 212da on the finger piece portion 212dy side protrudes outward from the housing recess 212 bf. Further, the end portion of the second moving member 212da on the notched portion 212dz side is slidably connected to the first inclined surface 212ga of the first moving member 212g, whereby the first moving member 212g moves toward the second moving member 212h in the first linear direction a.
Further, the second inclined surface 212gb of the first moving member 212g that moves is slidably connected to the third inclined surface 212ha of the second moving member 212h, whereby the second moving member moves to the opposite side of the locking convex portion 12db in the second linear direction B against the biasing force of the biasing member 212 i. As a result, the locking convex portion 12db is disengaged from the locking concave portion 11eb of the mounting
In this manner, the locking operation of the locking mechanism portion 212d can be performed by turning the operation knob 212 da.
Further, when the lock is released, since the operation handle 212da protrudes from the upper surface 212bg of the cover 212b from the end portion on the finger piece portion 212dy side, the user can hold the operation handle 212da to lift and detach the dust collecting device 212 from the mounting
Further, when the dust collection device 212 is remounted on the mounting
In this manner, the locking operation of the locking mechanism portion 212d can be performed by turning the operation knob 212 da.

In the first to third embodiments, the case where the upper outer surface of the operation handle and the upper surface of the lid portion of the dust collecting device are arranged in a flat substantially same surface is exemplified, but the outer surface of the operation handle and the upper surface of the lid portion may be arranged in a curved substantially same surface. In this way, the curved outer surface of the housing of the driving device and the upper surface of the dust collecting device can form a continuous surface, thereby improving the design.

(conclusion)
The electric dust collector of the invention comprises a dust collecting device and a driving device, wherein the dust collecting device is provided with a locking mechanism part, the driving device comprises a carrying part which can lock and unlock the dust collecting device by the locking mechanism part and is internally provided with an electric blower,
the dust collecting device has an operation handle capable of releasing the locking of the dust collecting device which is placed on the placing portion of the driving device and locked by the locking mechanism portion,
the unlocking operation of the operating handle is an operation of moving the operating handle in a direction different from a direction in which the operating handle is pulled up when the dust collecting device is lifted from the mounting portion after the unlocking operation.
According to this configuration, after the unlocking operation is performed by the operating handle, the dust collecting device can be lifted from the mounting portion of the driving device by performing a lifting operation different from the unlocking operation. Thus, even if the user lifts the operation handle by mistake during the transportation of the driving device, the locking of the locking mechanism part is not released, and the dust collecting device is not separated from the driving device. Further, according to this configuration, the operating handle is made difficult to grasp when the lock operation is released, so that it is possible to suppress an incorrect operation in which the user grasps the operating handle and lifts the driving device.
The electric vacuum cleaner of the present invention may have the following configuration, or may be an appropriate combination of these configurations.
The unlocking operation may be an operation of pressing the operation knob, an operation of rotating the operation knob, or an operation of pressing and rotating the operation knob.
With this configuration, the user can be made aware that the lifting operation of the release handle cannot be performed unless the release lock operation of the push or turn operation handle is performed.
The drive device has a locking recess in the placement portion,
the dust collecting device includes an outer portion having an exposed surface exposed to the outside in a state where the dust collecting device is mounted on the mounting device, and the lock mechanism portion provided on the outer portion,
the locking mechanism portion comprises the operation handle which can move in a approaching direction approaching to the exposed surface side of the external portion and a protruding direction protruding from the exposed surface; a locking convex part which can be locked with the locking concave part; a moving direction converting portion which can convert the unlocking operation into the linear movement of the locking convex portion,
the outer portion has a housing recess on the exposed surface, the housing recess housing the operating handle moving in the approaching direction,
the operating handle may have an outer surface disposed in substantially the same plane as the exposed surface of the outer portion in a state of being accommodated in the accommodating recess.
According to this configuration, since the operation knob before the lock release operation is stored in the storage recess of the exterior member and becomes a state in which it is difficult to grasp the operation knob, it is possible to suppress such an inappropriate operation that the user grasps the operation knob and lifts up the drive device.
The approach direction and the projection direction are the same first linear direction,
the first moving member, it has first inclined plane and couples to said operating handle movably in the said first straight line direction; a second moving member having a second inclined surface slidably connected to the first inclined surface of the first moving member moving in the first linear direction, and movable in a second linear direction substantially perpendicular to the first linear direction; a biasing member of an alternate operation type that biases the second moving member in a direction in which the second inclined surface presses the first inclined surface,
the locking protrusion may be coupled to the second moving member.
According to this configuration, after the dust collecting device is placed on the placing portion of the driving device while holding the operation handle in the protruding state, the first moving member is moved in the first linear direction by pressing (moving) the operation handle in the approaching direction, the second inclined surface is slidably connected to the first inclined surface of the moving first moving member, and the second moving member is moved in the second linear direction, so that the locking convex portion is locked to the locking concave portion, and the dust collecting device is placed in the locked state. At this time, the urging member is in a shortened state.
Further, by depressing the operation handle again, the urging member is depressed again via the first and second moving members to be in an extended state, and the second moving member is moved in the opposite direction by extending the urging member, and the locking protrusion is disengaged from the locking recess to release the lock, and the operation panel is automatically moved in the protruding direction via the second and first moving members. Thus, the dust collecting device can be detached from the mounting portion by lifting the operation handle.
The approach direction and the projection direction are the same first linear direction,
the operating handle is rotatably arranged on the outer part by taking an axis parallel to the first straight line direction as a center,
the moving direction converting part comprises a shaft part connected with the operating handle on the axis; a cam portion rotatably coupled to the shaft portion about the shaft center; a moving member slidably connected to the rotating cam portion and moving in a second linear direction substantially perpendicular to the first linear direction,
the locking protrusion may be coupled to the moving member.
According to this configuration, after the dust collecting device is placed on the placing portion of the driving device while holding the operation handle in the protruding state, the operation handle is pressed (moved in the approaching direction) and rotated in one direction about the shaft portion, so that the moving member is moved in the second linear direction by the rotating cam portion, and the locking convex portion is locked to the locking concave portion, thereby bringing the dust collecting device into the locked state.
Further, by rotating the operation knob in the opposite direction, the moving member is moved in the opposite direction by the rotating cam portion and the locking protrusion is disengaged from the locking recess to unlock, and the dust collecting device can be detached from the mounting portion by pulling up (moving in the protruding direction) the operation knob.
The movement direction conversion unit may further include a biasing member for biasing the operation handle in the protruding direction.
According to this configuration, the operation knob is automatically pushed out in the protruding direction by the urging member when the unlocking operation is performed, and therefore, the user can easily grasp the operation knob when the lifting operation is performed.
The operating handle is rotatably provided on the outer portion via a shaft,
the moving direction converting section includes a first moving member movable in a first linear direction substantially perpendicular to an axial center direction of the shaft, a second moving member movable in a second linear direction substantially perpendicular to the first linear direction, and a biasing member,
the first moving member has a first inclined surface and a second inclined surface, and the first inclined surface is slidably connected to the operating handle that rotates about the shaft; the second inclined surface is provided on the opposite side of the first inclined surface in the first straight line direction.
The second moving member has a third inclined surface slidably connected to the second inclined surface of the first moving member moving in the first linear direction,
the urging member urges the second moving member in a direction in which the third inclined surface presses the second inclined surface,
the locking protrusion may be coupled to the second moving member.
According to this configuration, after the dust collecting device is placed on the placing portion of the driving device while holding the operation handle in the protruding state, the second moving member is moved in the second linear direction by the urging member by rotating the operation handle in one direction (approaching direction) about the shaft portion, and the locking convex portion is locked to the locking concave portion, thereby bringing the dust collecting device into the locked state.
Further, by rotating the operating handle in the opposite direction (projecting direction), the first inclined surface is slidably connected to the operating handle and the first moving member moves in the first linear direction, the third inclined surface is slidably connected to the second inclined surface of the moving first moving member and the second moving member moves in the opposite direction against the biasing force of the biasing member, and the locking convex portion is disengaged from the locking concave portion and becomes the unlocked state. Therefore, the dust collecting device can be detached from the mounting portion by holding the operation handle.
Furthermore, the disclosed embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is indicated not by the above description but by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the claims.
