Description

The present invention relates to a vertical vacuum cleaner.

The conventional vertical vacuum cleaner has a handle part that is connected to the suction port body, and an electric blower and a vacuum cleaner body that is equipped with a dust collecting part. When the user rotates the operating body to change the moving direction of the suction port body on the floor, the operating body and the cleaner body rotate together, and a large force according to the weight of the cleaner body Hangs on the handle.
In order to reduce this, it is known to bring the center of gravity of the cleaner body closer to the straight line connecting the wheel and the handle provided at the rear portion of the suction port (see, for example, Patent Document 1).
JP 2005-110714 A (paragraph 0005)

However, as described in Patent Document 1, even if the center of gravity of the cleaner body is brought closer to the straight line connecting the wheel and the handle provided at the rear portion of the suction port body, cleaning is performed against the rotation of the operation body. It does not change that the machine body rotates integrally.
In addition, as a conventional vertical vacuum cleaner,
In the case where the vacuum cleaner body is attached to the operation body, there is a problem that the center of gravity of the vacuum cleaner body moves in the direction in which the operation body rotates, the rotation is promoted and the movement direction changes greatly.
When the vacuum cleaner body is attached to the operation body, the vacuum cleaner body is lifted in the direction opposite to the direction in which the operation body is rotated. There is a problem that it is difficult to change the moving direction because the overall center of gravity of the machine body is opposite to the moving direction of the suction port.
In the prior art, the influence of the weight of the main body of the cleaner on such a grip portion cannot be sufficiently reduced.

  This invention is made | formed by the said situation, and it aims at reducing the influence of the weight of a cleaner body with respect to rotation of the operation body for changing the moving direction of a suction inlet body.

In order to achieve the above object, in the vacuum cleaner of the present invention,
A vacuum cleaner body having an electric blower and a dust collecting portion communicating with the upstream side of the electric blower;
A suction body having a dust suction groove on the bottom surface and a connection part that supports the suction body so as to be rotatable in the left-right direction;
An operating body having a handle portion at one end and the other end connected to the connection portion of the suction port body,
And a rotation mechanism that rotatably supports the vacuum cleaner body around the operation body.

  According to the electric vacuum cleaner of the present invention, since the vacuum cleaner body is rotatably supported with respect to the operation body, the influence of the weight of the vacuum cleaner body on the rotation of the operation body for changing the cleaning direction is affected. It can be reduced.

Hereinafter, an embodiment of a vacuum cleaner according to the present invention will be described with reference to FIGS.

In the description in this specification,
The front means the forward direction of the vacuum cleaner 1, that is, the arrow direction A in FIG. 1, and the rear means the direction opposite to the arrow direction A.
The left-right direction means a direction substantially orthogonal to the arrow direction A.
Further, the gravity direction means the arrow direction B.

The vacuum cleaner shown in FIGS. 1 and 2 is a so-called vertical vacuum cleaner called a stick type or an upright type.
The vacuum cleaner includes a vacuum cleaner main body 18 including a dust collection unit 11 and an electric blower 12, and an air passage member connected to the vacuum cleaner main body 18.

This airway member
A suction body 19 having a dust suction groove on the bottom;
A suction port body 21 having a connection portion 20 connected to the suction body 19 and supporting the suction body 19 so as to be movable in the front-rear direction and pivotable in the left-right direction;
An operating body 28 comprising a handle 24 provided at one end with a handle 23 held by the user, and an extension pipe 27 having the other end connected to the connecting portion 20 of the suction port body 21;
The hose 26 etc. which connect the handle part 24 and the cleaner main body 18 are comprised.

Each air passage member is hollow, and the air passage is configured by connecting the hollow portions of these air passage members,
When the power switch 25 provided on the handle 23 is pressed, power is supplied to the electric blower 12, and the air containing dust sucked from the suction port body 21 by the operation of the electric blower 12 passes through the air passage to the cleaner body. The dust is collected into dust and air by 18 dust collecting portions 11 and exhausted from the exhaust port 15.

As shown in FIG.
The bearing 30 is sandwiched between the support member base 35 and the support member cover 36 formed in the vacuum cleaner main body 18, and is fastened with a screw 37 to constitute a rotation mechanism.

  By inserting the extension pipe 27 into the support part 33 assembled in this way, butting it against the step part below the extension pipe 27, the handle part 24 is inserted from above, and the upper and lower sides of the support part 33 are sandwiched. In addition to restricting the vertical movement, the cleaner body 18 is rotatably supported with respect to the extension pipe 27 of the operation body 28.

When storing a vacuum cleaner configured in this way,
As shown in FIG. 2, the vacuum cleaner main body 18 is locked by the locking means at a position where the operation body 28 stands on the floor surface and is positioned above the suction port body 21, and becomes a self-supporting state.

When using a vacuum cleaner,
When the handle 23 of the operation unit 24 is tilted backward by the user, the cleaner body 18 rotates in the direction of gravity around the support unit 33 as shown in FIG. It will be in the state supported so that rotation around was possible.

  In this state, the dust collected by the user from the suction port body 21 while being moved in the front-rear direction is collected in the dust collecting unit 11 through the air passage.

  Cleaning is performed while moving to the left and right along with the movement in the front-rear direction. For example, the direction change to the right direction while moving in the front direction is performed as follows.

When the user rotates the handle 23 of the operation unit 24 in the right direction together with the forward force, the operation body 28 connected to the operation unit 24 rotates in the right direction.
As a result of being transmitted to the suction main body 19 that is rotatably connected by the connection portion 20 bent in the shape of the rotation, the direction is changed by the suction main body 19 turning rightward.

  At this time, since the cleaner body 18 is rotatably supported by the support portion 33 with respect to the rotation of the operation body 28, it remains in the direction of gravity and does not rotate even if the operation body 28 rotates.

As described above, according to the present embodiment,
In a vertical vacuum cleaner,
With respect to the rotation of the operating body 28 consisting of the extension pipe 27 connected to the connection part 20 of the suction port body 21 with the other end made up of a handle part 24 provided with a handle 23 held at one end by the user. Since the vacuum cleaner main body 18 in which the dust collecting unit 11 and the electric blower 12 are disposed is rotatably supported by the support unit 33,
Even if the operating body 28 rotates, the cleaner body 18 stays in the direction of gravity and does not rotate.
The influence of the weight of the cleaner main body 18 on the rotation of the operating body 28 for changing the cleaning direction when the cleaner is used can be reduced.

  In the present embodiment, the bearing 30 is used as the rotation mechanism of the support portion 33 that rotatably supports the cleaner body 18. However, the present invention is not limited to this, and for example, as shown in FIG. The vacuum cleaner main body 18 is configured such that the bearing 30 in the support portion 33 is omitted, the operation body 28 is configured in a cylindrical shape, and the operation body 28 is directly sandwiched between the support member base 35 and the support member cover 36. The same structure can be used as long as it can be pivotally supported.

  Further, in the present embodiment, the operating body 28 and the connecting portion 20 are used as a part of the air path, but the present invention is not limited to this. For example, as shown in FIG. A machine body 18 that is directly connected by a hose 26 and that does not use the operating body 28 and the connecting portion 20 as an air passage can be similarly configured.

  Further, when it is necessary to largely depress the handle 24 in order to clean the underside of the table or the like using the electric vacuum cleaner of the present embodiment, the cleaner body 18 is directed in the direction opposite to the direction of gravity. By rotating and holding by the rotation prevention mechanism, the cleaner body 18 can be prevented from coming into contact with the floor surface.
