As shown in FIG. 1, the electric vacuum cleaner 1 according to Embodiment 1 includes a suction tool 2, a connection pipe 3, a suction hose 4, a cleaner body 5, a suction pipe 8, and a handle 9. The suction tool 2 includes a suction port body 6 and a connecting portion 7. The suction tool 2 is an example of a cleaning tool. The cleaner body 5 includes a hose connection port 11, a power cord 12, and wheels 13. The hose connection port 11 is located in the front part of the cleaner body 5. The wheels 13 are located on both sides of the rear half of the cleaner body 5.

  The suction port body 6 of the suction tool 2 sucks dust on the surface to be cleaned (hereinafter referred to as “surface to be cleaned”) together with air. The suction port body 6 is an example of a body. The connecting portion 7 connects the suction pipe 8 to the suction port body 6. The suction pipe 8 is an example of a wand. The wand is a tubular member or a rod-shaped member. One end of the suction pipe 8 may be detachable from the connecting portion 7. One end portion of the suction pipe 8 and a part of the connecting portion 7 may be integrated.

  The other end of the suction pipe 8 is connected to one end of the connection pipe 3. The connection pipe 3 is a cylindrical member that is bent halfway. The other end of the connection pipe 3 is connected to one end of the suction hose 4. The suction hose 4 is a flexible bellows-like member. The other end of the suction hose 4 is connected to the hose connection port 11 of the cleaner body 5. The vacuum cleaner body 5 is for separating dust from air containing dust and discharging the air from which the dust has been removed. Hereinafter, air containing dust is also referred to as “dusty air”. The air from which dust has been removed is also referred to as “clean air”. The clean air is returned from the cleaner body 5 to the room, for example.

  When the user performs cleaning using the electric vacuum cleaner 1, the user holds the handle 9. The handle 9 may be formed at least partially from a soft material such as gel. By forming the handle 9 at least partially from a soft material, the frictional force increases with the hand holding the handle 9 and the user can easily grip the handle 9. As a result, the operability of the suction tool 2 can be further improved. The handle 9 may be formed of a material that is softer than the suction pipe 8. The handle 9 may have a rod shape. The central axis of the rod-shaped handle 9 may coincide with the central axis of the suction pipe 8. In FIG. 1, the central axis of the handle 9 and the central axis of the suction pipe 8 are indicated by alternate long and short dash lines. When the overall shape of the handle 9 exhibits a rod-like shape coaxial with the central axis of the suction pipe 8, the hand movement and muscle load when the handle 9 is twisted are reduced. As a result, handling of the suction tool 2 is facilitated, and operability can be further improved. The handle 9 may be formed so that the cross-sectional area of the tip portion is larger than the cross-sectional area at the center in the longitudinal direction. The handle 9 may be formed such that the side farther from the suction port body 6 is thicker than the side closer to the suction port body 6 in the longitudinal direction.

  A double-headed arrow in FIG. 1 shows an example of how to move the handle 9. The movement in the twist direction A is a rotation around the central axis of the handle 9 and the suction pipe 8. The movement in the inclination direction B is a movement for changing the angles of the handle 9 and the suction pipe 8 with respect to the surface to be cleaned.

As shown in FIGS. 6 and 7, the accommodation unit 14 includes an intake air passage forming unit 20. The intake air passage forming unit 20 forms an intake air passage 21 for guiding dust-containing air to the dust collecting unit 15 in the cleaner body 5. The intake air passage forming unit 20 is provided so as to pass through the internal space of the container 16. One end of the intake air passage forming unit 20 opens at the front surface of the housing unit 14. The one end of the intake air passage forming unit 20 forms the hose connection port 11. The other end of the intake air passage forming unit 20 opens at the upper surface of the accommodation unit 14. That is, the other end of the intake air passage forming portion 20 is opened by the housing body 17. The other end of the intake air passage forming unit 20 forms a first connection port 18 connected to the dust collection unit 15.

  The dust collection unit 15 is for separating dust from dust-containing air and temporarily storing the separated dust. The dust collecting unit 15 separates dust from the air by centrifugal force by rotating the dust-containing air inside. That is, the dust collection unit 15 is a cyclone separation device having a cyclone separation function.

  As shown in FIGS. 6 and 7, the accommodation unit 14 includes an exhaust air passage forming unit 22. The exhaust air passage forming unit 22 forms an exhaust air passage 23 for guiding the clean air discharged from the dust collection unit 15 to an exhaust port (not shown) in the cleaner body 5. The exhaust air passage forming part 22 is provided so as to pass through the internal space of the container 16.

  As shown in FIGS. 6 and 7, an electric blower 24 is provided inside the accommodation unit 14. The electric blower 24 is for generating an airflow in each air passage formed in the vacuum cleaner 1. The air paths formed in the vacuum cleaner 1 are an air path for allowing dust-containing air to flow into the cleaner body 5 from the outside, an intake air path 21, a space in the dust collecting unit 15, and an exhaust air path. 23. The electric blower 24 is disposed in the exhaust air passage 23 at a preset position near the rear end of the housing unit 14.

  When the electric blower 24 starts the suction operation, an air flow is generated in each air passage formed in the vacuum cleaner 1. At this time, a suction force is generated inside the suction tool 2, the connection pipe 3, and the suction hose 4. The dust-containing air sucked into the suction port body 6 of the suction tool 2 is taken into the cleaner body 5 from the hose connection port 11. Dust-containing air that has flowed into the cleaner body 5 is sent to the dust collection unit 15 from the first connection port 18 via the intake air passage 21. Inside the dust collection unit 15, dust is separated from the dust-containing air. The clean air discharged from the dust collection unit 15 flows into the exhaust air passage 23 and passes through the electric blower 24 in the exhaust air passage 23. The clean air that has passed through the electric blower 24 further travels through the exhaust air passage 23 and is discharged from the exhaust port to the outside of the cleaner body 5.

  Next, the suction tool 2 will be described. In the following, as a general rule, a description will be given based on a state where the suction port body 6 is placed on a horizontal surface to be cleaned, that is, a state where a horizontal surface is cleaned. FIG. 8 is a schematic perspective view of the suction tool 2 of the first embodiment. FIG. 9 is a top view of the suction tool 2 of the first embodiment. FIG. 9 shows a state in which the longitudinal axis 82 of the suction pipe 8 is parallel to the short direction of the suction port body 6. FIG. 10 is a bottom view of the suction tool 2 of the first embodiment.

  As shown in FIGS. 8 to 10, the suction tool 2 includes a suction port body 6 and a connecting portion 7. FIG. 9 is a view of the suction port body 6 as viewed from above with the horizontal surface placed. When the suction port 6 is placed on a horizontal surface and viewed from above, the following is obtained. The length of the suction port body 6 in the longitudinal direction is L. The length of the suction port body 6 in the short direction is W. The short side direction is a direction perpendicular to the long side direction.

  In this Embodiment, the shape of the suction inlet 6 in top view is a rectangle or a rectangle. The length of the long side of the rectangle corresponds to L, and the length of the short side corresponds to W. Further, the shape of the suction port body 6 in a side view from the longitudinal direction and a side view from the short side direction is also a rectangle or a rectangle. That is, the suction inlet 6 of the present embodiment has a rectangular parallelepiped shape.

  Moreover, the shape which united the connection part 7 and the suction inlet body 6 is a rectangle by the top view. Thereby, with a small structure, a small turn is effective and the cleaning property is high.

  In the following description, the front, rear, left, and right when viewed from the user when the suction port body 6 is reciprocated in the short direction in a wide form to be described later and cleaned are defined as front, rear, left and right of the suction port body 6. 9, the left end 103 of the suction port body 6 in the longitudinal direction is the left end 103, the right end is the right end 104, the upper side is the front end 101, and the lower side is the rear end 102. When cleaning is performed by reciprocating the suction port body 6 in the lateral direction, the handle 9 is held on the rear end 102 side.

  In the top view of FIG. 9, the left end 103 and the right end 104 extend linearly. Not limited to such a configuration, the left end 103 and the right end 104 in a top view may be at least partially curved or broken. In this case, the length L in the longitudinal direction of the suction port body 6 indicates the maximum length in the longitudinal direction between the left end 103 and the right end 104 in a top view. In the present embodiment, the distance between the front end 101 and the rear end 102 of the suction port body 6 is generally constant along the longitudinal direction of the suction port body 6. Not only in such a configuration, the distance between the front end 101 and the rear end 102 of the suction port body 6 may change along the longitudinal direction of the suction port body 6. In this case, the length W in the short direction of the suction port body 6 indicates the maximum length in the short direction between the front end 101 and the rear end 102 in a top view.

  In the present embodiment, the connecting portion 7 is connected to the upper surface of the suction port body 6. The connecting portion 7 is on the upper surface side of the suction port body 6. The connection part 7 of this Embodiment is arrange | positioned in the center of the length L of the longitudinal direction of the suction inlet body 6. FIG. Not only such a structure but the connection part 7 may be arrange | positioned in the position biased from the center of the length L of the longitudinal direction of the suction inlet body 6. FIG.

  As shown in FIG. 8, the suction port 6 may include an upper case 31 and a lower case 32. The connecting part 7 in the present embodiment includes a first rotating part 71 and a second rotating part 72. The first rotating portion 71 rotates together with the suction pipe 8. The first rotating portion 71 rotates integrally with the suction pipe 8. The first rotating part 71 is rotatable about the first rotation axis X with respect to the second rotating part 72. The second rotating portion 72 is connected to the suction port body 6 so as to be rotatable about the second rotation axis Y. In FIG. 8, the first rotation axis X and the second rotation axis Y are indicated by alternate long and short dash lines.

  In the present embodiment, the first rotating portion 71 of the connecting portion 7 and the suction pipe 8 are integrally formed. Not only such a structure but the 1st rotation part 71 of the connection part 7 and the suction pipe 8 may be comprised by another member. The 1st rotation part 71 of the connection part 7 and the suction pipe 8 may be connected so that attachment or detachment is possible.

  As shown in FIG. 8, an air passage 81 is formed inside the suction pipe 8. As shown in FIG. 10, the suction port body 6 includes a suction opening 63. The suction opening 63 opens on the bottom surface 64 of the suction port body 6. The suction opening 63 is disposed at a position closer to the front end 101 than the rear end 102 of the suction port body 6. The bottom surface 64 of the suction port body 6 faces the surface to be cleaned during use, that is, during cleaning. An air passage that is fluidly connected to the suction opening 63 and the air passage 81 is formed inside the connecting portion 7. The air path inside the connecting portion 7 will be described later.

  When the electric blower 24 is activated, dust-containing air is sucked from the suction opening 63. Thereafter, the dust-containing air passes through the air passage inside the connecting portion 7 and the air passage 81 inside the suction pipe 8 and flows into the connection pipe 3.

  As shown in FIG. 10, a plurality of wheels 47 that support the suction port body 6 while being rolled with respect to the surface to be cleaned are attached to the bottom surface 64 of the suction port body 6. The rotation axis of the wheel 47 is parallel to the longitudinal direction of the suction port body 6. The plurality of wheels 47 include a wheel 47 that is in front of the center of the length W in the short direction of the suction port body 6 and a wheel 47 that is behind the center. The wheel 47 may use a soft material for the surface in particular.

  The wheel 47 rotates mainly when the suction port body 6 is moved in the short direction for cleaning. Compared with the structure which has the connection part 7 in the back of the suction inlet body 6 because the connection part 7 exists in the upper surface side of the suction inlet body 6, a power point becomes the front or upper direction. Therefore, when a force is applied forward, the suction port body 6 can be easily pulled forward. In the present embodiment, the provision of the wheel 47 in front of the center of the length W in the short direction of the suction port body 6 makes it possible to reduce the chance of such picking. Further, by using a soft material for the wheel 47, it is difficult to damage the contacted surface to be cleaned. For example, it is difficult to damage the surface to be cleaned even when the wheel 47 does not rotate, such as when the suction port body 6 is moved in the longitudinal direction for cleaning.

  FIG. 11 is a schematic cross-sectional view taken along the line HH in FIG. In FIG. 11, in order to simplify the drawing, the thickness of the wall of each part is ignored and the cross section of the wall is represented by a line. Hereinafter, with reference to FIG. 11, the suction tool 2 of this Embodiment is further demonstrated.

  The first rotation axis X is in a torsional position relationship with respect to the second rotation axis Y. The second rotation axis Y is substantially perpendicular to the longitudinal direction of the suction port body 6. As the second rotating portion 72 of the connecting portion 7 rotates about the second rotating shaft Y, the direction of the first rotating shaft X changes. The first rotating shaft X is relative to the second rotating shaft Y. To maintain the twisted position relationship. The second rotating portion 72 can rotate around the second rotation axis Y within a preset angle range with respect to the suction port body 6. The first rotating portion 71 of the connecting portion 7 can rotate around the first rotation axis X within a preset angle range with respect to the second rotating portion 72.

  An air passage communicating with the air passage 81 of the suction pipe 8 is formed inside the first rotating portion 71. The first rotating unit 71 includes a first shutter 71a and a second shutter 71b. The first shutter 71a and the second shutter 71b are walls having a circular cross section perpendicular to the first rotation axis X. A first rib 71c protruding outward is formed at the end of the first shutter 71a. A second rib 71d protruding outward is formed at the end of the second shutter 71b.

  The second rotating unit 72 includes a third shutter 72a and a fourth shutter 72b. The third shutter 72a and the fourth shutter 72b are walls having a circular arc shape in cross section perpendicular to the first rotation axis X. A third rib 72c projecting inward is formed at the end of the third shutter 72a. A fourth rib 72d that protrudes inward is formed at the end of the fourth shutter 72b.

  When the first rotating portion 71 rotates about the first rotation axis X with respect to the second rotating portion 72, the first shutter 71a enters and exits the inside of the third shutter 72a, and the second shutter 71b is the fourth shutter 72b. Go in and out of the inside. The rotation range of the first rotating portion 71 is restricted by the first rib 71c hitting the third rib 72c and the second rib 71d hitting the fourth rib 72d.

  A space surrounded by the first shutter 71a, the second shutter 71b, the third shutter 72a, and the fourth shutter 72b forms a part of the air path inside the connecting portion 7. According to such a structure, the air path inside the connection part 7 can be enlarged, pressure loss decreases, and suction performance improves.

  The suction port body 6 includes a protruding portion 65 that protrudes upward from the upper surface of the suction port body 6. An air passage 66 communicating with the agitator chamber 50 is formed inside the protrusion 65. The second rotating portion 72 is connected to the protruding portion 65 so as to be rotatable about the second rotation axis Y. An air path is formed inside the second rotating unit 72. The protrusion 65 has a circular opening with the second rotation axis Y as the center. The second rotating portion 72 has a circular opening with the second rotation axis Y as the center. At the joint 73 between the projecting portion 65 and the second rotating portion 72, the circular opening of the projecting portion 65 and the circular opening of the second rotating portion 72 are relatively rotatably connected.

  The air passage 66 inside the protruding portion 65 communicates with the air passage inside the second rotating portion 72 of the connecting portion 7. The inlet portion 67 serves as an inlet from the agitator chamber 50 to the air passage 66. The inlet 67 opens above the agitator chamber 50.

  In the following description, the first angle α and the second angle β are defined as follows. The first angle α is an inclination angle of the longitudinal axis 82 of the suction pipe 8 with respect to the horizontal plane. The second angle β is an angle between a straight line in the longitudinal direction of the suction port body 6 and a vertical plane including the longitudinal axis 82 of the suction pipe 8. In other words, as shown in FIG. 9, the angle between the straight line in the longitudinal direction of the suction port 6 and the straight line representing the longitudinal axis 82 of the suction pipe 8 is the second angle β as viewed from above. FIG. 9 shows a state where the first angle α is 0 ° and the second angle β is 90 °.

  As shown in FIG. 11, when the second angle β is 90 °, the first angle α is defined as 0 ° when the suction pipe 8 is tilted rearward of the suction port 6 and the longitudinal axis 82 becomes horizontal. To do. When the second angle β is 90 °, the first rotation portion 71 rotates about the first rotation axis X with respect to the second rotation portion 72, whereby the magnitude of the first angle α can be changed. The position of the suction pipe 8 indicated by the solid line in FIG. 11 represents a state where the first angle α is 0 °. The position of the suction pipe 8 indicated by a broken line in FIG. 11 represents a state where the first angle α is 90 °.

  For example, as shown in FIG. 11, the angle range in which the connecting portion 7 can rotate about the first rotation axis X changes from 0 ° to 90 ° when the second angle β is 90 °. It may be a possible range. The angle range in which the connecting portion 7 can rotate around the first rotation axis X may be larger, for example, a range in which the first angle α can vary from 0 ° to 135 ° or 180 °.

  The second rotation axis Y is inclined with respect to the vertical line. In the present embodiment, the second rotation axis Y is inclined so that the second rotation axis Y faces obliquely upward toward the front of the suction port body 6.

  In the following description, the absolute value of the acute angle formed by the vertical line and the second rotation axis Y is simply referred to as “the inclination angle of the second rotation axis Y”. The inclination angle of the second rotation axis Y is preferably 10 ° to 80 °. Within this range, the wobbling of the suction port body 6 when moving the suction port body 6 in the short direction for cleaning can be reliably suppressed, and it is easy to operate. Within the above range, the greater the inclination angle of the second rotation axis Y, the more reliably the wobbling of the suction port body 6 when the suction port body 6 is moved in the short direction for cleaning. The inclination angle of the second rotation axis Y is more preferably 45 ° or near (for example, a range of 40 ° to 50 °).

  If the inclination angle of the second rotation axis Y is as described above, the following effects can be obtained. Gravity acts on the friction between the suction port body 6 and the surface to be cleaned, and the inclination of the suction port body 6 is suppressed. As the tilt angle of the second rotation axis Y increases, the action of gravity increases, so the tilt can be further suppressed. Further, by twisting the handle 9 and the suction pipe 8, the direction of the suction port body 6 can be changed while maintaining the bottom surface 64 of the suction port body 6 parallel to the surface to be cleaned. Thereby, since the direction of the suction inlet body 6 can be changed without moving an arm or an elbow, a high cleaning property is obtained.

  When the cross-sectional shape of the air passage 81 in the suction pipe 8 is a polygon, the intersection of the vertical bisector of one side of the polygon and the vertical bisector of the other side is the length of the suction pipe 8. A line connected in the direction may be regarded as the longitudinal axis 82 of the suction pipe 8. When the cross-sectional shape of the air passage 81 in the suction pipe 8 is circular, a line connecting the center of the circle in the longitudinal direction of the suction pipe 8 may be regarded as the longitudinal axis 82 of the suction pipe 8.

  As the connecting portion 7 rotates around the first rotation axis X and the second rotation axis Y, the magnitude of the second angle β shown in FIG. 9 can be changed. The range in which the second angle β can change may be from 0 ° to 180 °.

  FIG. 12 is a rear view of the suction tool 2 of the first embodiment. In the rear view shown in FIG. 12, the range in which the angle of the longitudinal axis 82 of the suction pipe 8 with respect to the horizontal plane can be changed may be a range indicated by γ, that is, a range from 0 ° to 180 °.

  The first angle α and the second angle β increase or decrease as the connecting portion 7 rotates about the first rotation axis X and the second rotation axis Y. Usually, when using the suction tool 2, it cleans so that the bottom face 64 of the suction inlet body 6 may maintain the attitude | position in which the suction inlet body 6 was set | placed on the horizontal surface. Assuming that the second rotation axis Y is parallel to the vertical line, even if the suction port body 6 rotates about the second rotation axis Y, the bottom surface 64 of the suction port body 6 is maintained horizontal. For this reason, when it is assumed that the second rotation axis Y is parallel to the vertical line, when the suction port body 6 is moved in the short direction for cleaning, the frictional force between the surface to be cleaned is the suction port body. If the left and right sides of 6 are not equal, the suction port body 6 may rotate around the second rotation axis Y against the user's will. On the other hand, according to the present embodiment, it is possible to reliably prevent such a situation from occurring because the second rotation axis Y is inclined with respect to the vertical line. Further, since the second rotation axis Y is arranged at a position inclined with respect to the vertical direction of the upper surface of the suction port 6, the suction pipe 8 does not interfere and the rotation range can be increased.

  9 to 12 show a state where the second angle β is 90 °. As shown in FIGS. 9 and 10, in the state where the second angle β is 90 °, the size of the connecting portion 7 along the short direction of the suction port body 6 is the length of the suction port body 6 in the short direction. Less than W. As shown in FIG. 12, the connecting portion 7 has a symmetrical shape through a plane perpendicular to the bottom surface 64 through the center in the longitudinal direction when the second angle β is 90 °. Moreover, as shown in FIG. 9, the connection part 7 exists inside the outer edge of the suction inlet body 6 by the top view.

  In the suction tool 2 of the present embodiment, the longitudinal axis 82 of the suction pipe 8 can be substantially parallel to the longitudinal direction of the suction port body 6. For example, in FIG. 11, assuming that the inclination angle of the second rotation axis Y is 45 °, the first rotation portion 71 is set to the first rotation portion 72 with respect to the second rotation portion 72 so that the first angle α is 45 °. After the rotation about the rotation axis X, the second rotation part 72 is rotated 90 degrees to the left or right about the second rotation axis Y, so that the longitudinal axis 82 of the suction pipe 8 becomes the suction port body 6. It becomes a state substantially parallel to the longitudinal direction.

  In this specification, “substantially parallel” includes a range of ± 10 ° with respect to a completely parallel state.

  In the following description, for example, a narrow gap formed between furniture and the like is referred to as a “narrow portion”. In the present embodiment, the following effects can be obtained. Since the longitudinal axis 82 of the suction pipe 8 is substantially parallel to the longitudinal direction of the suction port body 6, the suction port body 6 is inserted to the back of the narrow portion having a depth and a low height. it can. For this reason, a narrow part with a depth and a low height can be easily cleaned.

  As shown in FIG. 11, the suction tool 2 of the present embodiment can be in a state in which the longitudinal axis 82 of the suction pipe 8 is substantially parallel to the lateral direction of the suction port body 6. By setting it in this state, it is possible to efficiently clean a low place having a depth, a wide width, and a low height.

  In the present embodiment, the connecting portion 7 is disposed inside the outer edge of the suction port body 6 in a top view, and the first angle α is in the range of 0 ° to 90 ° and the second angle β is in the range of 0 ° to 180 °. It can be rotated with. In other words, the width of the suction pipe 8 fits inside the length W of the suction port body 6 in the short direction. According to such a configuration, when the longitudinal axis 82 of the suction pipe 8 is substantially parallel to the longitudinal direction of the suction port body 6, the length W of the suction port body 6 in the short direction is set. Since each part fits in the range, the narrow part can be cleaned more easily. Moreover, when cleaning a low place, it fits in the height of the sum total of the suction inlet body 6 and the connection part 7. FIG. For this reason, it is excellent in cleaning property, and efficient cleaning becomes possible in a short time.

  FIG. 13 is a top view showing a usage pattern of the suction tool 2 of the first embodiment. FIG. 14 is a top view showing another usage pattern of the suction tool 2 of the first embodiment. FIG. 13 shows a usage pattern in which the suction port body 6 is moved along the short direction. FIG. 14 shows a usage pattern in which the suction port body 6 is moved along the longitudinal direction. Hereinafter, the usage pattern illustrated in FIG. 13 is also referred to as a “wide configuration”, and the usage configuration illustrated in FIG. 14 is also referred to as a “narrow configuration”.

  The user can operate the direction of the suction port body 6 of the suction tool 2 with a hand holding the handle 9 when cleaning using the electric vacuum cleaner 1. For example, when the handle 9 is rotated in the twist direction A shown in FIG. 1, the connecting portion 7 is rotated and the direction of the suction port body 6 is changed. The user can change the direction of the suction port body 6 when moving the handle 9 back and forth by operating the handle 9. In this case, the direction of the suction port body 6 can be changed between, for example, a wide form and a narrow form. By making the direction of the suction port body 6 wide, it is possible to easily clean a wide area. By narrowing the direction of the suction port body 6, it is possible to easily clean narrow places such as narrow portions.

  In the present embodiment, the following effects can be obtained. It is possible to change the usage form of the suction tool 2 between a wide form and a narrow form according to a condition. For example, when cleaning a wide area such as the center of a room, the cleaning range can be widened by using the suction tool 2 in a wide form. For example, when cleaning a narrow part such as a gap in furniture, the suction port body 6 can be inserted into the back of the narrow part by using the suction tool 2 in a narrow form. By simply changing the direction of the suction port body 6, it is possible to cope with cleaning of various scenes including wide areas and narrow areas. It is possible to reduce the necessity to remove and replace the attachment according to the place to be cleaned, and to reduce the burden on the user. Moreover, the specific dimension of the length L of the longitudinal direction of the suction inlet body 6 is not specifically limited. In the embodiment described above, in the wide form, the frictional force between the surface to be cleaned and the left end 103 side of the suction port body 6 and the frictional force on the surface to be cleaned and the right end 104 side of the suction port body 6 Even if a difference arises, it can suppress reliably that the 2nd angle (beta) in FIG. 13 fluctuates, and it can clean efficiently.

  As shown in FIGS. 10 and 11, the suction tool 2 includes an agitator 35 and a motor 37. The agitator 35 is rotatably attached to the suction port body 6. The rotation axis R <b> 1 of the agitator 35 is parallel to the longitudinal direction of the suction port body 6. As the agitator 35 rotates, the surface to be cleaned is agitated and dust is scraped up from the surface to be cleaned. When the suction port body 6 includes the upper case 31 and the lower case 32, the agitator 35 may be attached to the lower case 32. A driven wheel 36 is connected to one end side of the agitator 35. The driven wheel 36 rotates integrally with the agitator 35. The other end side of the agitator 35 is rotatably supported with respect to the suction port body 6 via the shaft 48.

  The motor 37 rotates the agitator 35. The motor 37 in the present embodiment is an electric motor. In the present invention, the motor 37 that rotates the agitator 35 is not limited to an electric motor, and may be a turbine that rotates by an air flow, for example. The motor 37 includes a drive shaft 38. The rotation axis R2 of the drive shaft 38 of the motor 37 is parallel to the rotation axis R1 of the agitator 35. The drive shaft 38 is connected to the driven wheel 36 via the drive belt 40. The driving force of the motor 37 is transmitted to the agitator 35 via the driving shaft 38, the driving belt 40, and the driven wheel 36, whereby the agitator 35 rotates. Further, instead of the illustrated configuration, the driving force of the motor 37 may be transmitted to the agitator 35 by other transmission means such as a gear train.

  The suction port body 6 includes a suction opening 63 and an agitator chamber 50. The agitator chamber 50 is formed inside the suction port body 6. The suction opening 63 is an opening formed in the bottom surface 64 of the suction port body 6. The agitator chamber 50 accommodates the agitator 35. A suction opening 63 is formed by opening at least a part of the lower surface of the agitator chamber 50. When the electric blower 24 is activated, dirty air is sucked from the suction opening 63. The suction port body 6 may further include a suction opening formed on a surface (for example, a side surface) other than the bottom surface 64 of the suction port body 6. In this case, the total opening area of the suction openings formed on the surface other than the bottom surface 64 of the suction port body 6 is preferably smaller than the total opening area of the suction openings 63 formed on the bottom surface 64 of the suction port body 6. By configuring as such, the following effects can be obtained. Since dust can be mainly sucked from the suction opening 63 formed on the bottom surface 64 of the suction port body 6, the variation in suction performance can be reduced.

  In the present embodiment, the rotation shaft R2 of the motor 37 is made parallel to the rotation shaft R1 of the agitator 35, so that the following effects can be obtained. The motor 37 can be arranged in a space-saving manner. The area of the suction opening 63 can be increased. The suction tool 2 can be reduced in weight. As shown in FIG. 10, in the present embodiment, the direction in which the drive shaft 38 protrudes from the motor 37 is the same direction as the direction in which the driven wheel 36 protrudes from the agitator 35.

  As shown in FIG. 11, the agitator 35 includes a cylindrical base body 43 and a protruding member 44. The protruding member 44 protrudes from the outer peripheral surface of the cylindrical base body 43. The protruding member 44 is held by a holding portion (not shown) provided on the cylindrical base body 43. As the projecting member 44, for example, fibrous brush hairs may be used, or a blade of soft material may be used, or a combination thereof may be used. The protruding members 44 may be arranged on the outer periphery of the cylindrical base body 43 along a spiral line centering on the rotation axis R1. In that case, the projecting members 44 may be arranged in at least two rows (for example, four rows), and valleys along the above-described spiral line may be formed between the rows. Alternatively, the protruding members 44 may be arranged on the outer periphery of the cylindrical base body 43 in parallel with the rotation axis R1. In the present embodiment, the motor 37 is disposed at a position close to the left end 103 of the suction port body 6. The motor 37 may be disposed at a position near the right end of the suction port body 6.

  In FIG. 11, the air path of the suction tool 2 is demonstrated. The dust-containing air sucked from the suction opening 63 travels upward from the agitator chamber 50, flows into the air passage 66 from the inlet portion 67, and reaches the position of the second rotation axis Y when it is refracted or curved. Then, it progresses to the suction pipe 8 side through the position of the first rotation axis X. That is, in the air path of the suction tool 2, the position of the first rotation axis X is downstream of the position of the second rotation axis Y.

  Temporarily, if the inlet part used as the inlet of the air path connected from the inside of the agitator chamber 50 to the inside of the connection part 7 is opened in the rear of the agitator chamber 50, the suction port body 6 is moved backward in the short direction. At this time, the relative velocity of the airflow with respect to the inlet portion decreases, and it becomes difficult for dust to enter the agitator chamber 50 from the inside of the agitator chamber 50, which may reduce the cleaning performance. Further, there may be a difference in suction performance between when the suction port 6 is advanced in the short direction and when it is retracted. On the other hand, according to the present embodiment, the inlet portion 67 serving as the inlet of the air passage 66 connected from the inside of the agitator chamber 50 to the inside of the connecting portion 7 is opened above the agitator chamber 50, thereby achieving the following effects. Is obtained. If it is this Embodiment, regardless of the moving direction of the suction inlet body 6, a difference in suction performance hardly arises and cleaning unevenness can be reduced.

  If it is this Embodiment, the following effects are acquired because the connection part 7 exists in the upper surface side of the suction inlet body 6. FIG. A downward force is applied to the entire suction port body 6, and the suction port body 6 is unlikely to float. In particular, the suction port body 6 easily sinks with a carpet or the like, so that high suction performance can be obtained.

Embodiment 2. FIG.
Next, the second embodiment will be described with reference to FIG. 15 to FIG. 17. The description will focus on the differences from the first embodiment described above, and the description of the same or corresponding parts will be simplified or described. Omitted.

  FIG. 15 is a schematic perspective view of the suction tool 2 of the second embodiment. FIG. 16 is a rear view of the suction tool 2 according to the second embodiment. FIG. 17 is a schematic cross-sectional view taken along the line JJ in FIG. In FIG. 17, in order to simplify the drawing, the thickness of the wall of each part is ignored, and the cross section of the wall is represented by a line.

  As shown in FIG. 17, in the second embodiment, the second rotation axis Y is inclined so that the second rotation axis Y faces obliquely downward toward the front of the suction port body 6. The position of the suction pipe 8 indicated by the solid line in FIG. 17 represents a state where the first angle α is 0 °. The position of the suction pipe 8 indicated by a broken line in FIG. 17 represents a state where the first angle α is 135 °. For example, as shown in FIG. 17, the angle range in which the connecting portion 7 can rotate about the first rotation axis X changes from 0 ° to 135 ° when the second angle β is 90 °. It may be a possible range.

  In the suction tool 2 according to the second embodiment, the longitudinal axis 82 of the suction pipe 8 can be substantially parallel to the longitudinal direction of the suction port body 6. For example, in FIG. 17, assuming that the inclination angle of the second rotation axis Y is 45 °, the first rotation portion 71 is set to the first rotation portion 72 with respect to the second rotation portion 72 so that the first angle α is 135 °. After the rotation about the rotation axis X, the second rotation part 72 is rotated 90 degrees to the left or right about the second rotation axis Y, so that the longitudinal axis 82 of the suction pipe 8 becomes the suction port body 6. It becomes a state substantially parallel to the longitudinal direction.

  According to the second embodiment, an effect similar to that of the first embodiment described above can be obtained.

Embodiment 3 FIG.
Next, the third embodiment will be described with reference to FIG. 18 to FIG. 20. The difference from the above-described embodiment will be mainly described, and the description of the same or corresponding parts will be simplified or omitted. To do.

  FIG. 18 is a rear view of the suction tool 2 of the third embodiment. FIG. 19 is a schematic perspective view of the suction port body 6 provided in the suction tool 2 of the third embodiment. 20 is a schematic cross-sectional view taken along the line KK in FIG. However, FIG. 20 shows a state when the second angle β is 90 °. In FIG. 20, in order to simplify the drawing, the thickness of the wall of each part is ignored, and the cross section of the wall is represented by a line.

  As shown in FIG. 19, the suction port 6 included in the suction tool 2 of the third embodiment includes a first upper surface 68 and a second upper surface 69. The second upper surface 69 is at a position lower than the first upper surface 68. In the rear portion of the suction port body 6, the first upper surface 68 is on the left side and the second upper surface 69 is on the right side with the connecting portion 7 as a boundary. In the front portion of the suction port body 6, there is a first upper surface 68 over the entire length of the suction port body 6 in the longitudinal direction. The suction port body 6 includes a support portion 610 that supports the connecting portion 7. The support part 610 will be described later. In FIG. 19, the illustration of the support portion 610 is simplified.

  In the second embodiment, an example in which the second upper surface 69 is formed on the right side of the suction port body 6 will be described, but the second upper surface 69 may be formed on the left side of the suction port body 6.

  As shown in FIG. 18, when the longitudinal axis 82 of the suction pipe 8 is substantially parallel to the longitudinal direction of the suction port body 6, the connecting portion 7 and the suction pipe 8 are at least partially It is located at a height between the upper surface 68 and the second upper surface 69. When the longitudinal axis of the suction pipe 8 is substantially parallel to the longitudinal direction of the suction port 6, the second upper surface 69 extends at least partially along the longitudinal direction of the suction pipe 8.

  According to the third embodiment, in addition to the effects similar to those of the first embodiment, the following effects can be obtained. Since the position of the suction pipe 8 is lower when the longitudinal axis 82 of the suction pipe 8 is substantially parallel to the longitudinal direction of the suction port body 6, it is possible to efficiently clean a low place having a low height. .

  The cross-sectional shape of the second upper surface 69 cut along a plane perpendicular to the longitudinal direction of the suction port body 6 is constant along the longitudinal direction of the suction port body 6 in at least a part of the second upper surface 69. When the longitudinal axis 82 of the suction pipe 8 is substantially parallel to the longitudinal direction of the suction port body 6, that is, in the state of FIG. 18, it may be as follows. The second upper surface 69 may be formed such that the distance between the second upper surface 69 and the suction pipe 8 is constant along the longitudinal direction of the suction port body 6. For example, when the suction pipe 8 has a cylindrical shape, at least a part of the second upper surface 69 may have a recessed shape. The suction pipe 8 may fall within a height range equal to or lower than the first upper surface 68.

  As shown in FIG. 18, the suction tool 2 of the third embodiment includes a motor 37. The motor 37 is an example of a driving unit that drives the agitator 35. The second upper surface 69 extends from the position of the connecting portion 7 to one end in the longitudinal direction of the suction port body 6, that is, the right end 104. The position of the motor 37 in the longitudinal direction of the suction port body 6 is on the other end side in the longitudinal direction of the suction port body 6 with respect to the connecting portion 7, that is, on the left end 103 side. Thereby, the following effects are acquired. The motor 37 needs a certain size in order to rotate the agitator 35 at high speed. If the motor 37 is disposed on the same side as the second upper surface 69 with respect to the connecting portion 7, the suction port body 6 is increased in size. On the other hand, according to the present embodiment, the suction port body 6 can be reduced in size by arranging the motor 37 on the side opposite to the second upper surface 69 with respect to the connecting portion 7.

  As shown in FIG. 20, the position of the second upper surface 69 is behind the position of the agitator chamber 50 with respect to the position of the suction port body 6 in the short direction. The upper end of the agitator chamber 50 is above the second upper surface 69. An air passage 611 communicating with the agitator chamber 50 is formed inside the support portion 610 that supports the connecting portion 7. The second rotating portion 72 is connected to the support portion 610 so as to be rotatable about the second rotation axis Y. An air path is formed inside the second rotating unit 72. The support portion 610 has a circular opening with the second rotation axis Y as the center. The second rotating portion 72 has a circular opening with the second rotation axis Y as the center. At the joint portion 73 between the support portion 610 and the second rotation portion 72, the circular opening of the support portion 610 and the circular opening of the second rotation portion 72 are relatively rotatably connected.

  The air passage 611 inside the support portion 610 communicates with the air passage inside the second rotating portion 72 of the connecting portion 7. The inlet 612 serves as an inlet from the agitator chamber 50 to the air passage 611. The inlet portion 612 opens above the agitator chamber 50.

  In the third embodiment, the second rotation axis Y is inclined so that the second rotation axis Y faces obliquely upward toward the front of the suction port body 6. The position of the suction pipe 8 indicated by the solid line in FIG. 20 represents a state where the first angle α is 0 °. The position of the suction pipe 8 indicated by a broken line in FIG. 20 represents a state where the first angle α is 90 °. For example, as shown in FIG. 20, the angle range in which the connecting portion 7 can rotate about the first rotation axis X changes from 0 ° to 90 ° when the second angle β is 90 °. It may be a possible range.

  In the suction tool 2 of the third embodiment, the longitudinal axis 82 of the suction pipe 8 can be substantially parallel to the longitudinal direction of the suction port body 6. For example, in FIG. 20, assuming that the inclination angle of the second rotation axis Y is 45 °, the first rotation portion 71 is first with respect to the second rotation portion 72 so that the first angle α is 45 °. After rotating around the rotation axis X, the second rotation part 72 is rotated 90 ° clockwise about the second rotation axis Y, so that the longitudinal axis 82 of the suction pipe 8 is in the longitudinal direction of the suction port body 6. It becomes a substantially parallel state.

  The rotation angle of the connection part 7 may be limited by the connection part 7 being disposed at a position lower than the first upper surface 68. The second angle β may be rotatable between 0 ° and 180 °. When the second angle β is 0 ° to 90 °, the first angle α may be rotatable at 0 ° to 90 °. When the second angle β is larger than 90 °, the rotation range of the first angle α is narrowed.

  According to the third embodiment, the following effects can be obtained. The height of the suction tool 2 can be suppressed by lowering the installation position of the connecting portion 7. For this reason, since it is excellent in the operativity at the time of cleaning of low places, such as under a sofa, cleaning property improves. In addition, since the position of the connecting portion 7 is low, it is possible to prevent the suction tool 2 from floating and picking up with the lower front end of the suction port body 6 as a fulcrum, thereby improving operability. By making the right end 104 side of the suction port body 6 lower than the left end 103 side, the suction port body 6 can be rotated from the wide form to the narrow form by twisting the handle 9 and the suction pipe 8 clockwise. . A right-handed person is more likely to turn in a clockwise direction. A greater force is required when changing from the wide configuration to the narrow configuration than when returning. When returning from the narrow configuration to the wide configuration, the load is less because of the resilience, a smaller force is required than from the wide configuration to the narrow configuration.

  In the present embodiment, the suction pipe 8 has a circular cross section. At least a part of the second upper surface 69 has an arc-like cross-sectional shape along the outer peripheral surface of the suction pipe 8.

  If it is this Embodiment, since the width | variety when it is set as a narrow form is only the width | variety of the suction inlet body 6, it is excellent in the cleanability of a narrow place. Moreover, when cleaning the place where height is low, it becomes the height only for the height of the suction inlet body 6. For this reason, when it cleans with a narrow form, since it becomes possible to clean without the connection part 7 and the suction pipe 8 interfering with the cleaning location vicinity, it is excellent in the cleanability of a low place.

Embodiment 4 FIG.
Next, the fourth embodiment will be described with reference to FIG. 21 and FIG. 22. The difference from the above-described embodiment will be mainly described, and the description of the same or corresponding parts will be simplified or omitted. To do.

  FIG. 21 is a top view of the suction tool 2 according to the fourth embodiment when used in a wide form. FIG. 22 is a top view of the suction tool 2 according to the fourth embodiment when used in a narrow form.

  In the first to third embodiments described above, the position of the connecting portion 7 in the longitudinal direction of the suction port body 6 is at the center of the suction port body 6 in the longitudinal direction. Not only in such a configuration, the position of the connecting portion 7 in the longitudinal direction of the suction port body 6 may be biased toward the left end 103 side or the right end 104 side with respect to the longitudinal center of the suction port body 6. .

  As shown in FIGS. 21 and 22, in Embodiment 4, the position of the connecting portion 7 in the longitudinal direction of the suction port body 6 is toward the right end 104 side with respect to the longitudinal center of the suction port body 6. The case where it is biased will be described as an example. It is not limited to this example, The position of the connection part 7 about the longitudinal direction of the suction port body 6 may be biased toward the left end 103 side with respect to the center of the suction port body 6 in the longitudinal direction.

  According to the fourth embodiment, in addition to the effects similar to the above-described embodiment, the following effects can be obtained. Since the rotation radius at the time of rotating the suction inlet body 6 centering on the connection part 7 in top view can be enlarged, more efficient cleaning becomes possible. When cleaning a low place having a height higher than that of the suction port body 6 and lower than that of the connecting portion 7, the low place is reduced to a length close to the full length of the suction port body 6 by adopting the narrow form of FIG. 22. The suction port body 6 can be inserted into. When the suction port body 6 moves in the wide form, even if the position of the connecting portion 7 is not at the center in the longitudinal direction of the suction port body 6, the second rotation axis Y is inclined with respect to the vertical line. The suction port body 6 can be reliably prevented from rotating around the second rotation axis Y, and can be efficiently cleaned.

When applied to a floor mop, the body of the cleaning tool can hold a textile or sponge for cleaning. When the cleaning tool of the present invention is applied in addition to the suction tool 2 for the electric vacuum cleaner, the body may not include the suction opening, the wand may be a rod-shaped member, and the connecting portion may not include the air path. .
