Description

Stick type vacuum cleaner

The present invention relates to a stick type vacuum cleaner that can be stored upright.

Generally, a stick type vacuum cleaner has a vertically long shape. Therefore, the stick type vacuum cleaner can be stored upright in a relatively narrow space formed in a living space such as a living room (see, for example, Patent Document 1).

In other words, in a stick-type vacuum cleaner, storage is an important factor. Therefore, it is desirable that the stick type vacuum cleaner has a structure that can be stored in a narrower space.

Hereinafter, the present embodiment will be described with reference to the drawings. The present invention is not limited to the embodiments.

(Embodiment)
Below, the structure of the stick type | formula vacuum cleaner (this may be abbreviated as "vacuum cleaner" hereafter) of this Embodiment is demonstrated with reference to FIG. 1 and FIG.

FIG. 1 is a side view of the vacuum cleaner 1 according to the present embodiment. FIG. 2 is a front view of the vacuum cleaner 1 of FIG.

As shown in FIG. 1, the vacuum cleaner 1 of the present embodiment includes a main body 10 and a suction tool unit 20.

The main body 10 includes a housing 11, a handle 12, an extension pipe 60, a suction unit 70, a dust collection unit 80, a dust box 90, a battery unit 100, and the like. The housing 11 and the extension tube 60 have an elongated shape. One end of the extension pipe 60 is connected to one end of the housing 11. The suction tool unit 20 is connected to the other end of the extension pipe 60. In addition, the longitudinal direction of the housing 11 and the extension pipe 60 is defined by the longitudinal direction ZA that is the longitudinal direction of the cleaner 1 shown in FIG. A direction perpendicular to the paper surface of FIG. 1 is defined by the width direction ZB.

The handle 12 is attached to the other end of the housing 11. The user operates the vacuum cleaner 1 by grasping the handle 12.

The suction unit 70, the dust collection unit 80, the dust box 90, and the battery unit 100 are attached to the rear surface of the housing 11. In the vertical direction ZA, the units of the dust box 90, the dust collection unit 80, the suction unit 70, and the battery unit 100 are arranged in order from the extension tube 60 side. At this time, the longitudinal directions of the suction unit 70, the dust collection unit 80, the dust box 90, and the battery unit 100 are arranged in parallel with the longitudinal direction ZA of the cleaner 1.

The outer diameters of the case 71 of the suction unit 70, the case 81 of the dust collection unit 80, the case 91 of the dust box 90, and the case 101 of the battery unit 100 are approximately equal (including cases where they are equal). The outer diameter defines the maximum dimension of the main body 10 in the width direction ZB (hereinafter, “maximum width of the main body 10”).

The suction unit 70 includes an electric blower 72 inside. The electric blower 72 generates a suction force for sucking dust. The dust collection unit 80 is constituted by, for example, a centrifugal dust collector, and separates dust and air sucked by the suction unit 70. The dust box 90 accommodates the dust compressed by the dust collection unit 80. The battery unit 100 supplies power to the suction blower unit 20 and the electric blower 72 of the suction unit 70.

In addition, in the front view of the cleaner 1 shown in FIG. 2, the direction orthogonal to the longitudinal direction ZA of the cleaner 1 is the width direction ZB of the cleaner 1.

The dimensions in the width direction ZB of the housing 11 and the extension pipe 60 are approximately equal (including the case where they are equal). The dimensions of the suction unit 70, the dust collection unit 80, the dust box 90, and the battery unit 100 in the width direction ZB are approximately equal (including the case where they are equal). The dimension of each unit in the width direction ZB is larger than the dimension of the housing 11 and the extension pipe 60 in the width direction ZB.

As described above, the vacuum cleaner 1 of the present embodiment is configured.

Hereinafter, the configuration of the suction tool unit 20 will be described with reference to FIGS. 2 to 6.

FIG. 3 is a perspective view of the suction tool unit 20 of FIG. FIG. 4 is a bottom view of the suction tool unit 20 of FIG. FIG. 5 is a cross-sectional view of the suction tool unit 20 of FIG. 6 is a cross-sectional view taken along line 6-6 of FIG.

3 and 4, the suction tool unit 20 includes a suction tool 30 and a connecting pipe 40. The suction tool 30 includes a case 31, a shutter 32, a rotating brush 33, and a roller 34. 2, the dimension of the suction tool 30 in the longitudinal direction ZD is larger than the maximum width of the main body 10, for example, the dimension of the suction unit 70 in the width direction ZB.

As shown in FIG. 4, the case 31 includes a suction port 31Q that opens to the bottom surface 31P. The rotating brush 33 is disposed in the suction port 31Q. The shutter 32 is provided at a portion on the front side of the case 31 so as to be movable with respect to the case 31. Thereby, the shutter 32 opens or closes the front portion of the case 31. When the portion on the front side of the case 31 is opened, the suction port 31Q also opens on the front side of the case 31 (see FIG. 10).

The roller 34 is provided on the front surface of the shutter 32 and rotates in the longitudinal direction ZD of the suction tool 30. The roller 34 enables smooth movement of the suction tool 30 when the suction tool 30 moves in the width direction ZB while being in contact with a wall or a floor surface.

The rotating brush 33 includes a base material 33a, a plurality of first bristle brushes 33b, and a plurality of second bristle brushes 33c. The base material 33 a is supported by the case 31 in a state where the base material 33 a can rotate with respect to the case 31. The plurality of first bristle brushes 33b and second bristle brushes 33c are planted alternately in the circumferential direction on the outer circumference of the base material 33a. The first bristle brush 33b is planted on the base material 33a with no gap in the longitudinal direction of the base material 33a (corresponding to the longitudinal direction ZD of the suction tool 30). Each of the plurality of second bristle brushes 33c includes a plurality of unit brushes 33d planted at a constant interval in the longitudinal direction of the base material 33a. Thereby, a gap 33e through which air can flow smoothly is formed between the adjacent unit brushes 33d. Therefore, in the state where the shutter 32 is opened, the air in front of the case 31 flows into the case 31 through the gap 33e. In this case, the resistance to the flowing air is smaller than when the gap 33e is not formed. Thereby, the suction | attraction force of the suction tool unit 20 increases. As a result, dust can be efficiently collected with less power.

Further, the connecting pipe 40 is connected to the extension pipe 60 shown in FIG. As shown in FIG. 5, the suction tool 30 is rotatably connected to the connection pipe 40 around a first axis JX <b> 1 that is a rotation center axis of the connection pipe 40.

Therefore, the vacuum cleaner 1 can take a plurality of forms according to the rotation of the suction tool 30. The plurality of forms include, for example, a first form, a second form, and a third form, which will be described below with reference to FIGS. 6 to 8, 13, and 19.

1st form is a form which consists of a 1st state which the suction tool 30 used for cleaning of the floor surface FL takes. As shown in FIG. 2, the first state is a state in which the longitudinal direction ZD of the suction tool 30 is parallel to the width direction ZB of the cleaner 1.

2nd form is a form which consists of a 2nd state which the suction tool 30 takes, when the vacuum cleaner 1 passes in the process changed from a 1st form to a 3rd form. As shown in FIG. 13, the second state is a state in which the longitudinal direction ZD of the suction tool 30 is orthogonal to the longitudinal direction ZA of the cleaner 1 in a side view of the cleaner 1. Therefore, a 2nd form is taken when cleaning the floor surface FL of a narrow clearance gap between furniture, for example.

3rd form is a form which consists of the 3rd state which the suction tool 30 used when arrange | positioning the vacuum cleaner 1 in predetermined | prescribed storage places, such as a stand. As shown in FIG. 19, the third state is a state in which the longitudinal direction ZD of the suction tool 30 is arranged along the longitudinal direction ZA of the main body 10 in the front view of the cleaner 1.

The suction tool 30 further includes a nozzle motor 35 and a rotation control unit 36 as shown in FIG. The nozzle motor 35 and the rotation control unit 36 are accommodated in the case 31. The nozzle motor 35 is driven by electric power supplied from the battery unit 100 (see FIG. 1), and rotates the rotating brush 33.

The case 31 includes a communication pipe 31a and a support part 31b. The communication pipe 31a is provided in the case 31 so as to communicate with the suction port 31Q that opens to the bottom surface 31P. The support portion 31 b supports the connection pipe 40 in a portion inserted into the case 31 so as to be rotatable with respect to the suction tool 30.

The connecting pipe 40 includes a first connecting pipe 41, a second connecting pipe 42, a restricting portion 43, and the like. The first connection pipe 41 is disposed in the case 31 and is connected to the communication pipe 31a. The first connecting pipe 41 includes a flange 41a on the outer periphery. The flange 41a is accommodated in the support portion 31b. The second connecting pipe 42 is connected to the extension pipe 60 in a state in which it cannot rotate with respect to the extension pipe 60 (see FIG. 1).

The connecting portion 40X between the first connecting pipe 41 and the second connecting pipe 42 is constituted by a ball joint. The connecting portion 40X includes at least a second axis JX2 along the width direction ZB of the cleaner 1 as a rotation center axis.

The regulating part 43 is attached to the case 31 so as to cover a part of the connecting part 40X. The restricting portion 43 restricts the first connecting pipe 41 and the second connecting pipe 42 from rotating around an axis other than the second axis JX2. Thereby, the 1st connecting pipe 41 and the 2nd connecting pipe 42 rotate relatively only around the 2nd axis JX2.

The suction tool unit 20 further includes a rotating structure S. The rotating structure S rotates the suction tool 30 relative to the main body 10 so that the longitudinal direction ZD of the suction tool 30 is along the longitudinal direction ZA of the main body 10 (see FIG. 2).

Rotating structure S includes a first rotating structure S1 and a second rotating structure S2. The first rotating structure S1 rotates the suction tool 30 with respect to the connecting pipe 40 around the first axis JX1. The second rotating structure S2 rotates the suction tool 30 with respect to the connecting pipe 40 around the second axis JX2. Note that the second rotating structure S2 includes a connecting portion 40X between the first connecting pipe 41 and the second connecting pipe 42, and a restricting portion 43.

1st axis | shaft JX1 is arrange | positioned along the orthogonal direction ZE orthogonal to the longitudinal direction ZD in the planar view of the suction tool 30 shown in FIG. Specifically, the first axis JX1 is disposed, for example, at the center in the longitudinal direction ZD of the suction tool 30 and in the center in the height direction ZF (thickness direction).

On the other hand, the second axis JX2 is arranged along the width direction ZB in the front view of the main body 10 shown in FIG. The second axis JX2 is disposed, for example, at the center position of the suction tool 30 in the height direction ZF.

The connecting pipe 40 further includes a lock mechanism 50. The lock mechanism 50 locks the relative rotation between the first connecting pipe 41 and the second connecting pipe 42. That is, the lock mechanism 50 can take an unlocked state in which the first connecting pipe 41 and the second connecting pipe 42 can be rotated relative to each other and a locked state in which the rotation is impossible.

The lock mechanism 50 includes a protruding portion 51 formed on the second connecting pipe 42 and a convex portion 52 formed on the restricting portion 43. The locked state and the unlocked state are configured by the presence or absence of the fitting between the protruding portion 51 and the protruding portion 52.

As described above, the suction tool unit 20 of the present embodiment is configured.

Hereinafter, the configuration and operation of the first rotating structure S1 of the rotating structure S of the suction tool unit 20 will be described with reference to FIGS.

First, the configuration of the first rotating structure S1 will be specifically described.

1st rotation structure S1 is comprised by the rotation control part 36 provided with the piston 36a and the elastic member 36b. The rotation control unit 36 controls the rotation of the suction tool 30 with respect to the connecting pipe 40 around the first axis JX1. The piston 36 a is arranged in the case 31 so as to be in contact with the flange 41 a of the first connecting pipe 41 in a state in which the piston 36 a is movable in the longitudinal direction ZD of the case 31. The elastic member 36b is disposed in the case 31 so as to give a biasing force that presses the piston 36a against the flange 41a. The elastic member 36b is exemplified by a coil spring, for example. The flange 41a is formed in a quadrangle, for example.

The flange 41a has protrusions 41b protruding toward the support portion 31b at two adjacent corners on the side opposite to the piston 36a that comes into contact.

The support portion 31b includes, for example, an arc-shaped wall portion 31c provided on the opposite side of the piston 36a with respect to the first axis JX1 in the longitudinal direction ZD of the suction tool 30.

As described above, the first rotating structure S1 of the rotating structure S is configured.

Next, the operation of the first rotating structure S1 will be described.

As shown in FIG. 6, first, when the suction tool 30 is in the first state, the entire top surface 36aa of the piston 36a of the rotation control unit 36 is pressed against the first side surface 41d of the flange 41a. Thereby, one protrusion 41b formed at the corner of the flange 41a is pressed against the wall portion 31c of the support portion 31b. Therefore, a frictional force is generated between the flange 41a and the piston 36a and the wall portion 31c. The frictional force acts as a resistance against the force that relatively rotates the suction tool 30 and the first connecting pipe 41. As a result, the suction tool 30 can easily maintain the first state.

Next, when a force for rotating the suction tool 30 and the first connection pipe 41 is applied, the suction tool 30 and the connection pipe 40 rotate relatively. Thereby, the contact position of the flange 41a and the piston 36a changes. At this time, when the rotation angle of the suction tool 30 is less than a predetermined angle, the biasing force by the elastic member 36b of the rotation control unit 36 acts to return the rotation position of the suction tool 30 to the rotation position of the first state. . Therefore, normally, even if a user does not apply rotational force to the suction tool 30 and the connection pipe 40, the suction tool 30 returns to a 1st state. The rotation angle is a rotation angle of the suction tool 30 when the first state of the suction tool 30 is used as a reference. The predetermined angle is 45 °.

Then, as shown in FIG. 7, when the rotation angle of the suction tool 30 reaches a predetermined angle (45 °), the top surface 36aa of the piston 36a comes into contact with the top portion 41e of the flange 41a. As a result, the piston 36a is pushed most into the elastic member 36b side. If the rotation angle of the suction tool 30 is further increased from this state, the suction tool 30 and the connecting pipe 40 rotate relatively. As a result, the top surface 36aa of the piston 36a comes into contact with the second side surface 41f of the flange 41a.

Next, as shown in FIG. 8, when the rotation angle of the suction tool 30 reaches the maximum angle, the entire top surface 36aa of the piston 36a is pressed against the second side surface 41f of the flange 41a. The maximum angle is 90 °. Thereby, the suction tool 30 will be in the above-mentioned 2nd state. At this time, the other protrusion 41b formed at the corner of the flange 41a contacts the side surface 36ab of the piston 36a. Therefore, the suction tool 30 and the 1st connection pipe 41 cannot rotate in the direction where the rotation angle of the suction tool 30 increases further.

Further, when the rotation angle of the suction tool 30 exceeds a predetermined angle (45 °) and is less than the maximum angle (90 °), the biasing force of the elastic member 36b of the rotation control unit 36 causes the suction tool 30 to It works to be close to the rotation position of the state. Therefore, even if it does not give rotational force to the suction tool 30 and the connecting pipe 40, the suction tool 30 rotates and changes to the second state. As a result, high operability can be obtained.

As described above, the first rotating structure S1 of the rotating structure S operates.

Hereinafter, the operation of the cleaner 1 will be described with reference to FIGS. 9 to 11 and 19.

First, as shown in FIG. 9, when the vacuum cleaner 1 taking the first form is used for cleaning the floor surface FL, the shutter 32 of the suction tool 30 closes the front part of the case 31.

From the above state, as shown in FIG. 10, when the cleaner 1 approaches the wall surface WS, the shutter 32 is pressed against the wall surface WS. As a result, the shutter 32 moves relative to the case 31 so as to rotate backward while the front is lifted, and the front part of the case 31 is opened. Therefore, air also flows into the case 31 from the front side of the case 31. As a result, the dust present at the corner C constituted by the floor surface FL and the wall surface WS can be easily sucked.

Further, when the cleaner 1 is used, for example, for cleaning a narrow space between furniture, the cleaner 1 is changed to the second form as shown in FIG.

In the second embodiment, first, the shutter 32 of the suction tool 30 is pressed against the floor surface FL. In this case, as in the first embodiment, the shutter 32 moves relative to the case 31, and the front part of the case 31 is opened. Therefore, air also flows into the case 31 from the front side of the case 31. As a result, dust existing on the floor surface FL in the gap between the furniture can be easily sucked.

Furthermore, when the cleaner 1 is disposed in a predetermined storage location such as a stand, for example, the cleaner 1 is changed to the third form as shown in FIG.

In the third embodiment, the suction tool 30 is arranged such that the longitudinal direction ZD is along the longitudinal direction ZA of the main body 10 in the front view of the vacuum cleaner 1. Thereby, the dimension of the longitudinal direction ZD of the suction tool 30 becomes smaller than the dimension of the width direction ZB of the cleaner 1 in a 1st form. Therefore, the cleaner 1 can be stored in a narrower space. Further, the dimension of the suction tool 30 in the height direction ZF is narrower than the maximum width of the main body 10. Therefore, the vacuum cleaner 1 can be accommodated in a much smaller space.

As described above, the vacuum cleaner 1 operates.

Hereinafter, a procedure for changing the configuration of the vacuum cleaner 1 from the first configuration to the third configuration will be described with reference to FIGS. 12 to 14.

As shown in FIG. 12, first, the suction tool 30 indicated by the dotted line, which takes the first state in the first mode, is rotated around the second axis JX2 in the rotation direction R shown in the figure. At this time, the suction tool 30 is rotated until the orthogonal direction ZE (see FIG. 5) is parallel to the longitudinal direction ZA of the main body 10.

Next, the suction tool 30 is rotated around the first axis JX1 in the rotation direction W1 shown in FIG. Thereby, as shown in FIG. 13, the suction tool 30 will be in a 2nd state.

Next, the suction tool 30 is rotated around the second axis JX2 in the rotation direction R1 shown in FIG. At this time, as shown in FIG. 14, the longitudinal direction ZD of the suction tool 30 rotates so as to follow the longitudinal direction ZA of the main body 10. Thereby, the suction tool 30 will be in the 3rd state shown in FIG.

By the above operation, the cleaner 1 completes the change from the first form to the third form.

Hereinafter, the state of the lock mechanism 50 corresponding to each form of the suction tool 30 will be described.

First, the state of the lock mechanism 50 in the process in which the suction tool 30 changes from the second state to the third state will be described with reference to FIGS. 15 and 16.

FIG. 15 shows the relationship between the suction tool 30 and the connecting pipe 40 in the process in which the state of the suction tool 30 changes from the second state to the third state. FIG. 16 is an enlarged view showing the state of the lock mechanism 50 in this state.

As shown in FIG. 15 and FIG. 16, in the process in which the suction tool 30 changes from the second state to the third state, the convex portion 52 and the protruding portion 51 constituting the lock mechanism 50 are not caught. Therefore, a gap G is formed between the end 41c of the first connecting pipe 41 and the outer peripheral surface 42a of the second connecting pipe 42. Thereby, the lock mechanism 50 is maintained in the unlocked state.

Next, the state of the lock mechanism 50 when the suction tool 30 is in the third state will be described with reference to FIGS. 17 and 18.

FIG. 17 shows the relationship between the suction tool 30 and the connecting pipe 40 when the suction tool 30 takes the third state. FIG. 18 is an enlarged view showing the state of the lock mechanism 50 in this state.

When the suction tool 30 is in the third state, as shown in FIGS. 17 and 18, the convex portion 52 and the protruding portion 51 constituting the lock mechanism 50 are caught. Thereby, rotation to the one side of the suction tool 30 and the connecting pipe 40 around the second axis JX2 is restricted.

In the above state, the end 41c of the first connecting pipe 41 and the outer peripheral surface 42a of the second connecting pipe 42 are in contact with each other. Thereby, the rotation to the other of the suction tool 30 and the connecting pipe 40 around the second axis JX2 is also restricted.

Thus, a state in which the suction tool 30 is locked by the lock mechanism 50 is formed.

Therefore, when the cleaner 1 is stored in a stand or the like in a locked state, the suction tool 30 does not rotate with respect to the main body 10 even if the cleaner 1 is moved. Thereby, workability | operativity when accommodating the cleaner 1 improves.

(Modification)
In the said embodiment, although the example of the form which a stick type vacuum cleaner can take was demonstrated, it is not restricted to the said embodiment.

That is, the stick type vacuum cleaner of the present embodiment can take a form in which, for example, the following modification example of the embodiment and at least two modification examples that do not contradict each other are combined. .

Specifically, the arrangement of FIG. 19 has been described as an example of the position of the suction tool 30 that narrows the maximum width of the vacuum cleaner 1, but is not limited to this arrangement. For example, the suction tool 30 may be disposed on the back side of the main body 10 and below the dust box 90. Also in this case, the maximum width of the cleaner 1 can be narrowed as in the case of the arrangement of the suction tool shown in FIG.

Also, the configuration of the lock mechanism that locks the suction tool 30 can be arbitrarily changed. For example, instead of the lock mechanism 50, the cleaner 1 may be configured to include a lock mechanism that fixes the suction tool 30 to the extension pipe 60 when the suction tool 30 is in the third state. For example, the lock mechanism may be configured to fix the suction tool 30 by using a magnetic force between a magnet provided in the suction tool 30 and a magnet provided in the extension pipe 60. Furthermore, the suction tool 30 may be configured to be fixed by fitting a part of the suction tool 30 and a part of the extension pipe 60 together.

As described above, the stick type vacuum cleaner of the present invention has a rotating structure that can rotate the suction tool with respect to the main body so that the longitudinal direction of the suction tool is along the longitudinal direction of the main body, and the length of the suction tool. A locking mechanism that locks rotation of the suction tool relative to the main body in a state where the direction is along the longitudinal direction of the main body.

According to this configuration, when the longitudinal direction of the suction tool is along the longitudinal direction of the main body, the dimension in the width direction in the front view of the stick type vacuum cleaner is shortened. Thereby, a stick type vacuum cleaner can be accommodated in a narrower space. Moreover, in the said state, rotation of a suction tool can be locked with a locking mechanism. Thereby, workability | operativity at the time of accommodating a stick type vacuum cleaner improves.

Further, the stick type vacuum cleaner of the present invention may be configured such that the height of the suction tool is the same as the maximum width of the main body or narrower than the maximum width in a state where the longitudinal direction of the suction tool is along the longitudinal direction of the main body. . Thereby, a vacuum cleaner can be accommodated in a still narrower space.

In the stick type vacuum cleaner of the present invention, the rotating structure has a first rotating structure for rotating the suction tool around a first axis orthogonal to the height direction of the suction tool and the longitudinal direction of the suction tool, and a main body. It is good also as a structure containing the 2nd rotation structure which rotates a suction tool around the 2nd axis | shaft orthogonal to the longitudinal direction of a main body in front view. Thereby, it becomes easy to suck in the dust existing on the floor surface FL of the gap between furniture and the like.

In the stick type vacuum cleaner of the present invention, when the longitudinal direction of the suction tool is in the first state along the second axis, and the longitudinal direction of the suction tool is in the second state orthogonal to the second axis, When the rotation angle of the suction tool based on the first state is less than a predetermined angle, a force is applied to the suction tool so that the rotation position of the suction tool approaches the rotation position in the first state. And when the rotation angle of a suction tool is more than a predetermined angle, you may further provide the rotation control part which gives force to a suction tool so that the rotation position of a suction tool may approach the rotation position in a 2nd state. Thereby, even if a user does not apply rotational force to a suction tool and a connection pipe, a suction tool can be easily returned to a 1st state.

The present invention can be applied to various stick-type vacuum cleaners for home use and business use.
