  The vacuum cleaner main body 1 includes a main body portion 10, a motor case portion 11, and a handle portion 12.

  The main body 10 is formed with a connection port 10a (suction port) to which an extension pipe 300 (see FIG. 1), a standard suction port 400 (see FIG. 1) and the like are connected. The connection port 10a is formed of the same resin as the main body 10, the motor case 11, the handle 12, and the like. The connection port 10a has a substantially circular opening and is formed with the axial direction facing forward. Further, the connection port 10a includes the gap / brush switching nozzle 110, the extension pipe 300, the standard suction port 400, the small suction port 600, the broom suction port 700, and the like as accessories (hereinafter may be collectively referred to as an attachment). Can be connected.

  The main body 10 is provided with an introduction pipe 14 (see FIG. 3) to which the dust case 2 is detachably attached and air containing dust sucked from the connection port 10a is sent to the dust case 2.

  The motor case portion 11 includes an electric blower 40 (see FIG. 6) and a main body substrate 50 (see FIG. 6). In addition, a circular suction port 11 a into which clean air collected by the dust case 2 is sucked is formed on the front surface of the motor case portion 11. A main body terminal portion 17 connected to the charging base 70 is provided on the front surface of the motor case portion 11 below the suction port 11a.

  The handle portion 12 is provided on the rear side of the main body portion 10 and has a grip portion 12a formed in a substantially L shape. The grip portion 12a includes a first grip portion 12a1 that extends linearly in the front-rear direction and a second grip portion 12a2 that extends linearly in the substantially vertical direction. The 1st holding part 12a1 is located in the upper part and the front side rather than the 2nd holding part 12a2. The second grip portion 12a2 is slightly inclined so that the upper portion is directed forward with respect to the vertical direction. Further, the first grip portion 12a1 and the second grip portion 12a2 are formed in a substantially rod shape and continuously. As described above, both the first gripping portion 12a1 and the second gripping portion 12a2 are configured in a straight line, so that the user can easily recognize the position of the handle. Further, since the first gripping part 12a1 and the second gripping part 12a2 are connected so as to be bent at an angle close to a right angle, the hand is shifted to the second gripping part 12a2 when gripping the first gripping part 12a1. On the other hand, when the second gripping portion 12a2 is gripped, it is difficult for the hand to slip to the first gripping portion 12a1.

  The handle portion 12 is provided with a lock member 13 for locking the storage battery 3. The lock member 13 is formed in a button shape and is supported so as to be swingable.

  An operation button 12b is provided on the upper surface of the first gripping portion 12a1 of the handle portion 12. The operation button 12b includes, for example, three buttons “strong”, “standard”, and “off”.

  A release button 18 that is operated when an accessory such as the extension pipe 300 (see FIG. 1) is removed is provided on the upper front end of the main body 10. By depressing the release button 18, the lock between the main body 10 and the accessory is released, and the accessory can be removed from the main body 10.

  An airtight holding member 90 is attached to the front end of the main body 10. The hermetic holding member 90 has a substantially circular cylindrical body 91. The cylindrical body 91 has an elastic portion 91a formed in an annular shape with a soft resin on the tip side. The cylindrical body 91 is formed of a material harder than the elastic portion 91 a on the base end side, and has a connection portion 91 b that can be connected to the main body portion 10. The cylindrical body 91 is configured by integrally molding two different members of an elastic portion 91a and a connecting portion 91b. The elastic portion 91a is made of an elastically deformable (flexible deformable) material such as an elastomer. By attaching such an airtight holding member 90 to the connection port 10a of the cleaner body 1, the entire tip 90s of the airtight holding member 90 can be brought into close contact with the floor surface, and the suction force is improved as compared with the case where the airtight holding member 90 is not in close contact. Can be made. In addition, by forming the connecting portion 91b with a hard material, the airtight holding member 90 can be attached to the main body portion 10 in a stable state without falling off.

  In the present embodiment, the case where the elastic portion 91a is formed of an elastic material such as an elastomer has been described as an example. However, the present invention is not limited to this. For example, substantially the entire cylindrical body 91 may be formed of the same material as that of the connection portion 91b, and short hairs electrostatically implanted at the tip of the cylindrical body 91 may be provided in an annular shape. Even with such electrostatic flocking, the tip of the airtight holding member 90 can be brought into close contact with the floor surface as in the case of an elastomer, and the suction force can be improved.

  A long and narrow fitting groove 10 b is formed on the outer surface of the connection port 10 a of the main body 10. The fitting groove 10b is formed on each of the left and right sides. At the base end of the connecting portion 91b, a protrusion (not shown) is formed that is engaged with the fitting groove 10b to be engaged and locked.

  Moreover, the light emitting element 10c (refer FIG. 2) is provided in the main-body part 10 above the connection port 10a. The light emitting element 10c is configured to emit light toward the front, that is, the surface to be cleaned (floor surface or the like). In addition, the tip surface 10c1 of the light emitting element 10c is located on substantially the same plane as the tip 10a1 of the connection port 10a.

  The storage battery 3 supplies electric power to the electric blower 40 (see FIG. 6) and is composed of a secondary battery such as lithium ion or nickel metal hydride. The storage battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and is detachable from the main body 10 by sliding the case 3a in the front-rear direction.

  A terminal portion 3b connected to the main body portion 10 is provided on the upper surface of the case 3a. In addition, a slide groove 3c that is slidably supported by the main body portion 10 is formed in front of the terminal portion 3b on the upper surface of the case 3a. In addition, on the upper surface of the case 3a, slide rails 3d and 3d that are slidably supported by the main body portion 10 are formed on the rear side of the terminal portion 3b so as to protrude leftward and rightward.

  In addition, on the front surface of the case 3a, an introduction hole 3e into which cooling air for cooling the storage battery 3 is introduced is formed on one side (left side) in the left-right direction (width direction). The introduction hole 3e is elongated in the vertical direction.

  In addition, a discharge hole 3f through which air after cooling the storage battery 3 is discharged is formed on the front surface of the case 3a on the other side (right side) in the left-right direction (width direction). The discharge hole 3f is formed so as to have a symmetrical shape with the introduction hole 3e.

  Further, a lock recess 3g is formed on the back surface of the case 3a so that the lock member 13 is fitted and locked to the main body 10.

3 is a view in the direction of the arrow X in FIG.
As shown in FIG. 3, the dust case 2 is of a cyclone type, and has a function of separating the air containing the dust sucked from the introduction pipe 14 into dust and air and collecting the dust. The dust case 2 is disposed in front of the motor case portion 11 with the axial direction being the front-rear direction, and has a substantially cylindrical storage portion 2a. Further, a substantially rectangular inflow port 2 b (see FIG. 2) connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust case 2. The air containing dust flowing into the inflow port 2b becomes a swirl flow, centrifugal force acts on the dust, and after the dust and air are separated in the dust case 2, the air from which the dust is separated is the dust case. 2 is discharged from the rear (rear).

  A lid 2c that opens and closes when the dust accumulated in the dust case 2 is discarded is supported on the front surface of the dust case 2 via a hinge portion 2d. In addition, a lid lock mechanism 2e for releasing the lock of the lid 2c is provided on the top of the lid 2c. In addition, about the mechanism inside the dust case 2, it can comprise based on Unexamined-Japanese-Patent No. 2006-137165.

  An exhaust port 16 is provided at the lower portion of the motor case portion 11. The exhaust port 16 has a plurality of slits 16a along the front-rear direction, and the plurality of slits 16a are formed side by side in the vertical direction. Although not shown, the exhaust ports 16 are provided on both the left and right sides.

FIG. 4 is a perspective view of the vacuum cleaner of the present embodiment.
As shown in FIG. 4, in the vacuum cleaner 100, the dust case 2 is attached below the main body 10 and in front of the motor case 11. In this case, when the dust case 2 is attached to the cleaner body 1, the lid lock mechanism 2 e is hidden on the cleaner body 1 side. This is because when the lid lock mechanism 2e is provided on the opposite side (outside), the lid lock mechanism 2e may be released during cleaning, but the lid lock mechanism 2e should be hidden behind the cleaner body 1 side. This is because malfunction can be prevented. For example, the vacuum cleaner main body 1 may be brought close to the floor surface horizontally, for example, when cleaning the bottom of a sofa or bed in a stick state. At this time, when the lid locking mechanism 2e is provided on the front side, there is a possibility that the lid locking mechanism 2e is released by contacting the floor surface. The positions of the lid lock mechanism 2e and the hinge portion 2d are not limited to this, and the lid lock mechanism 2e and the hinge portion 2d may be provided on the left and right with respect to the cleaner body 1.

  The dust case 2 is detachably provided with a maintenance brush 2s (see FIGS. 2 and 3). The care brush 2s is disposed at a position that is difficult to see from the outside when the dust case 2 is attached to the cleaner body 1. For this reason, it is hard to come off during driving, and it is not necessary to store the care brush 2s in a place different from the vacuum cleaner 100.

  Further, when the airtight holding member 90 is attached to the cleaner body 1, the light emitting element 10 c is covered by the airtight holding member 90. In other words, in the airtight holding member 90, the inner diameter of the airtight holding member 90 is set so that the light emitting element 10c is positioned inside the airtight holding member 9.

FIG. 5 is a plan view of the electric vacuum cleaner of the present embodiment.
As shown in FIG. 5, the connection part 91b of the airtight holding member 90 is formed with extension parts 91b1 and 91b1 extending rearward on both the left and right sides. A concave portion 91b2 is formed between the left extending portion 91b1 and the right extending portion 91b1 in plan view. The concave portion 91b2 is fitted to the front end portion 10d1 of the protruding portion 10d formed on the top surface of the front end of the main body portion 10. Accordingly, the airtight holding member 90 is positioned in the front-rear direction and the left-right direction with respect to the connection port 10a (see FIG. 2).

  The introduction pipe 14 formed in the main body 10 is formed to extend obliquely rearward to the right and then extend downward, and is connected to the inlet 2b (see FIG. 2) of the dust case 2. Thereby, a swirl | vortex flow can be generated in the accommodating part 2a of the dust case 2, and the separation of dust by a centrifugal force can be performed effectively.

  The widths of the dust case 2 and the storage battery 3 are slightly shorter than the width W of the main body 10. In other words, the dust case 2 and the storage battery 3 are configured not to protrude from the side of the main body 10. Thereby, even if a user carries out cleaning with either left or right hand, the vacuum cleaner 100 can be smoothly moved in the front-rear direction, and usability can be improved.

6 is a cross-sectional view taken along line VI-VI in FIG. FIG. 6 shows a state where the airtight holding member 90 is removed from the vacuum cleaner 100.
As shown in FIG. 6, an electric blower 40 is accommodated in the motor case portion 11 of the main body portion 10. Further, in the motor case portion 11, a main body substrate 50 (control substrate) for controlling the cleaner main body 1 is accommodated below the electric blower 40.

  The electric blower 40 is placed horizontally so that the rotational drive shaft 40a faces in the front-rear direction (horizontal direction). Further, the air discharged from the electric blower 40 flows into the main body substrate 50 disposed below the electric blower 40 to cool the main body substrate 50. A part of the air that has cooled the main body substrate 50 cools the storage battery 3.

  The main body substrate 50 has an upper substrate 50a and a lower substrate 50b that are divided into two stages and are arranged in two stages, and various components are mainly disposed on opposing surfaces (the lower surface of the upper substrate 50a and the upper surface of the lower substrate 50b). Has been implemented. Most of the air discharged from the electric blower 40 flows so as to cool the components (heat generating components) arranged opposite to each other of the main body boards 50. The main body substrate 50 is covered with a flame retardant resin case 51, and the wind (air) discharged from the electric blower 40 flows from the rear side to the front side in the resin case 51, and the resin It flows through the lower side of the bottom of the case 51 to the storage battery 3 side.

  Moreover, the electric blower 40 and the main body board | substrate 50 are arrange | positioned so that it may overlap with an up-down direction. For this reason, the dimension of the front-back direction can be shortened. Moreover, the electric blower 40 can shorten the dimension of the front-back direction (full length) of the main-body part 10 because the motor case part 11 bulges in the handle | steering-wheel part 12 side, and is formed.

  In addition, the electric blower 40 and the main body substrate 50 are located below the first grip portion 12a1 of the handle portion 12. As a result, when the user grips and operates the grip portion 12a1, the center of gravity of the vacuum cleaner 100 is near the lower portion of the first grip portion 12a1, so when using the tip of the vacuum cleaner 100 upward, the vacuum cleaner The machine 100 can be stably held.

  Further, a gap 12c having a width dimension H1 for inserting a hand is formed between the first gripping part 12a1 and the upper surface 11c of the motor case part 11. Further, a gap 12d having a width H2 wider than the width H1 is formed between the second grip 12a2 and the back surface 11d of the motor case 11. As described above, when the first grip portion 12a1 is gripped and cleaned, the arm can be held in an extended state, so that the vacuum cleaner 100 can be moved back and forth without gripping the first grip portion 12a1 strongly. it can. Further, when gripping and cleaning the second gripping part 12a2, it is necessary to insert a hand (finger) deeply into the gap 12d and grip it strongly, so by making the width dimension H2 wider than the width dimension H1, The second grip portion 12a2 can be stably gripped.

  Moreover, the thickness T1 of the first grip 12a1 is formed thin, and the thickness T2 of the second grip 12a2 is formed thicker than the thickness T1. That is, the first grip portion 12a1 is thin and the second grip portion 12a2 is thick. As described above, when the second gripping portion 12a2 is gripped and cleaned, the thickness of the second gripping portion 12a2 can be increased to increase the strength of the second gripping portion 12a2. it can.

  The storage battery 3 can be composed of, for example, an energy efficient lithium ion battery. Further, the storage battery 3 is disposed below the second grip portion 12 a 2 of the handle portion 12. Thus, by providing the storage battery 3 at the rear end of the vacuum cleaner 100, the center of gravity of the handle portion 12 is close to the second gripping portion 12a2, so that when the tip of the vacuum cleaner 100 is used upward, the operational feeling Can be lightened.

  The lock member 13 is formed with a button-type operation portion 13a at the rear end. The operation portion 13 a has an arm portion 13 b extending forward, and the front end of the arm portion 13 b is supported by the main body portion 10. The arm portion 13b is urged downward by a spring 13c. Thereby, when the lock member 13 is fitted and locked in the lock recess 3g, the operation portion 13a is prevented from coming out of the lock recess 3g. Moreover, when removing the storage battery 3 from the main-body part 10, the operation part 13a can come out of the lock recessed part 3g, repelling the urging | biasing force of the spring 13 by pressing the operation part 13a.

  Thus, by making the storage battery 3 detachable, it becomes easier to replace the storage battery 3 than when the storage battery is non-detachable. In addition, by preparing a spare storage battery 3 and a charging box that can charge the spare storage battery 3 as an option, when the storage battery on the main body side of the vacuum cleaner 100 is exhausted, by replacing it with the spare storage battery 3, It becomes possible to extend the cleaning time. Such a configuration is effective, for example, when cleaning a large floor such as a store.

  As shown in FIG. 6, when the surface passing through the front end surface of the connection port 10a of the main body 10 is R1, the front end 2f of the dust case 2 and the surface R1 (surface extending in the vertical direction with respect to the paper surface) are approximately. It is comprised so that it may become flush. Note that the tip 2f of the dust case 2 does not protrude forward from the surface R1. Thereby, even if it is a case where it cleans in the state which does not attach the airtight holding member 90 to the cleaner body 1, it can clean, making the front-end | tip of the connection port 10a contact hard floor surfaces, such as a flooring.

  A filter 5 is accommodated in the dust case 2 at the axial rear end of the accommodating portion 2a. The filter 5 is configured to be folded in a pleat shape, and can increase the filter area and reduce the pressure loss due to the filter 5.

  Moreover, the filter 5 is comprised, for example by the high-density HEPA filter (High Efficiency Particulate Air Filter). A HEPA filter is an air filter having a particle collection rate of 99.97% or more with respect to particles having a rated air volume of 0.3 μm and an initial pressure loss of 245 Pa or less.

FIG. 7 is a side view of the vacuum cleaner of the present embodiment.
As shown in FIG. 7, the vacuum cleaner 100 has an exhaust port 16 for discharging the sucked air to the outside. The exhaust port 16 is formed at a height position of the main body substrate 50 (see FIG. 6). A louver (air path switching member) 16b is attached to the outer surface of the exhaust port 16 so as to cover a plurality of slits 16a (see FIG. 3). In FIG. 7, the exhaust port 16 on the front side of the drawing is closed by the louver 16b, and the exhaust port on the opposite side is open.

  The airtight holding member 90 is formed so that the tip (tip surface) 90s is inclined so as to recede from the upper part toward the lower part. The dust case 2 is located behind the surface R2 passing through the tip 90s. Thereby, even when the tip 90s of the airtight holding member 90 is brought into contact with a floor surface such as flooring, the dust case 2 can be prevented from hitting the floor surface.

8 is a cross-sectional view taken along line VIII-VIII in FIG.
As shown in FIG. 8, the slit 16a of the exhaust port 16 is formed in a substantially semicircular wall 16c divided into left and right. A plurality of slits 16a are formed on the wall surface 16c on the left and right. The louver 16b is slidably provided along the wall surface 16c. The louver 16b is formed with protrusions 16b1 and 16b1 at both ends in the circumferential direction. In FIG. 8, the louver 16b is located on the left side (the right side in the figure), and the right side (the left side in the figure) slit 16a is exposed.

  In the main body substrate 50, an upper substrate 50a and a lower substrate 50b are arranged apart from each other in the vertical direction, and are accommodated in a case 51 made of a flame-retardant resin that is formed in a concave shape. The case 51 has a bottom surface portion 51a and left and right side surface portions 51b and 51c. For this reason, the upper substrate 50a and the lower substrate 50b cannot be visually recognized from the outside through the slit 16a of the exhaust port 16. Thereby, in the vacuum cleaner 100, it can prevent that a foreign material penetrate | invades from the outer side of the exhaust port 16, and contacts the main body board | substrate 50. FIG.

  Further, the exhaust port 16 is formed so as to communicate with the motor case portion 11, and is configured such that the exhaust from the electric blower 40 cools the main body substrate 50 and is then discharged from the slit 16 a. Moreover, since the exhaust port 16 is located in the lower part of the motor case part 11, it becomes possible to suppress that exhaust hits a user. Further, since the exhaust port 16 of the present embodiment can freely change the left and right direction of the exhaust, it is possible to prevent the exhaust from directly hitting the user regardless of whether the user is right-handed or left-handed.

  Further, on the surface of the louver 16b, ridge portions 16b1 and 16b1 projecting outward are formed. Thereby, when moving the louver 16b to the left and right, it becomes easy to hook a finger on the protruding portion 16b1, thereby facilitating the operation of moving the louver 16b to the left and right, and changing the direction of the exhaust gas quickly and easily. be able to.

9 is a cross-sectional view taken along line XI-XI in FIG.
As shown in FIG. 9, in the storage battery 3, six unit cells 3h (battery cells) are arranged in the case 3a side by side in the vertical direction. Further, the upper three unit cells 3h1 are arranged such that the center cell 3h1 at the left and right is lower than the unit cells 3h1 on the left and right sides, and the center of the unit cell 3h1 when the unit cell 3h1 is viewed from the axial direction. Are arranged in a V shape. Similarly, the lower three cells 3h2 are also arranged in a V shape. Thus, the width of the storage battery 3 can be made narrower by orienting the axial direction of the unit cell 3h (3h1, 3h2) in the front-rear direction than in the case where the axial direction of the unit cell 3h is directed in the left-right direction. Moreover, the width of the storage battery 3 can be further reduced by arranging the unit cells 3h1, 3h2 in two upper and lower stages and arranging the unit cells 3h1, 3h2 in a V shape. Thus, it can reduce that the storage battery 3 contacts a user during cleaning by narrowing the width | variety on either side.

  Thus, by disposing the unit cells 3h in a V shape, a recess 3i is formed on the upper side of the case 3a. In the case 3a, the above-described slide groove 3c is formed so as to protrude toward the recess 3i. On the other hand, a rail section 15 having a T-shape in cross section is formed on the main body portion 10 (below the handle portion 12) facing the slide groove 3c so as to project the slide groove 3c in a slidable manner. Thus, by forming the slide groove 3c in the dead space, the space can be used effectively, and the height dimension of the storage battery 3 can be kept low.

  Further, the cell 3h is accommodated in the case 3a while being held by a synthetic resin holding member 3j. The holding member 3j is configured such that gaps 3k1 and 3k1 are formed between the upper unit cell 3h1 and the lower unit cell 3h2. Further, a gap 3k2 is formed between the upper surface of the holding member 3j and the upper surface of the case 3a. Further, gaps 3k3 and 3k3 are formed between the left and right side surfaces of the holding member 3j and the side surface of the case 3a. Further, gaps 3k4 and 3k4 are formed between the lower surface of the holding member 3j and the bottom surface of the case 3a.

  By forming such gaps 3k1, 3k2, 3k3, 3k4, air can flow around each unit cell 3h, and each unit cell 3h (3h1, 3h2) can be effectively cooled.

FIG. 10 is a perspective view showing a state in which the battery is removed from the electric vacuum cleaner of the present embodiment as seen from the rear and obliquely rearward.
As shown in FIG. 10, the air that has cooled the main body substrate 50 (see FIG. 8) is led out from the main body 10 (the vacuum cleaner main body 1) on the back surface of the motor case portion 11 (the surface facing the front surface of the storage battery 3). A lead hole 11s to be discharged (discharged) is formed. The lead-out hole 11s is formed at a position facing the introduction hole 3e (see FIG. 2) of the storage battery 3. In other words, the lead-out hole 11 s and the introduction hole 3 e communicate with each other when the storage battery 3 is mounted on the main body 10. The communication direction between the lead-out hole 11s and the introduction hole 3e is the front-rear direction.

  The main body portion 10 is formed with hanging portions 10e and 10e that hang from the left and right ends below the handle portion 12. On the inner wall surface of the hanging part 10e, a projecting part 10f projecting inward is formed extending in the front-rear direction. The left protrusion is not shown. Thereby, the storage battery 3 is supported by the main body part 10 by sliding the slide rails 3d and 3d on the protruding part 10f with the storage battery 3 facing the front side from the back side (rear side) of the cleaner body 1. And the storage battery 3 is locked to the main-body part 10 with the lock member 13 because the back surface part 3m of the case 3a of the storage battery 3 abuts against the rear end face of the hanging part 10e. At this time, the lead-out hole 11s of the main body 10 and the introduction hole 3e (see FIG. 2) of the storage battery 3 are in communication with each other, and the air led out from the lead-out hole 11s is introduced into the introduction hole 3e (see FIG. 2). .

FIG. 11 is a perspective view showing a state in which the electric vacuum cleaner of the present embodiment is looked up from below.
As shown in FIG. 11, a holding plate 11 t that holds the louver 16 b is formed at the lower end of the motor case portion 11. The movement of the louver 16b in the right direction is restricted by the left ridge 16b1 coming into contact with the left edge of the holding plate 11t. Similarly, when the right ridge 16b1 (see FIG. 8) abuts on the right edge of the holding plate 11t, the operation of the louver 16b in the left direction is restricted. Thus, holding the louver 16b by the holding plate 11t can prevent the louver 16b from falling off the motor case portion 11. Further, by holding the louver 16b by the holding plate 11t, the louver 16b, which is a movable member, does not come into contact with the floor surface or the like, and the louver 16b can be prevented from being damaged.

  A support portion 11p having a flat surface 11p1 is formed on the lower surface of the motor case portion 11 in front of the exhaust port 16. On the other hand, a support part 3p having a rectangular plane 3p1 is formed on the lower surface of the storage battery 3. The plane 11p1 and the plane 3p1 are located on the same plane. Thereby, when the cleaner body 1 is placed on the floor surface in a handy state, the support portions 3p and 11p are supported in a posture in which the axial direction of the connection port 10a faces a horizontal direction parallel to the floor surface.

FIG. 12 is a front view of the electric vacuum cleaner of the present embodiment.
As shown in FIG. 12, the main body 10 is provided with an airtight holding member 90 so as to surround the connection port 10a. The hermetic holding member 90 has an opening 90t having a diameter larger than the diameter D of the connection port 10a. The opening 90t is formed so that the length in the vertical direction is longer than the length in the horizontal direction, and has a substantially elliptical shape when viewed from the axial direction.

  The main body 10 (the vacuum cleaner main body 1) has connection terminals 10u and 10u that are electrically connected to the various attachments described above (see FIG. 1, excluding the broom suction port 700) above the connection port 10a. Has been. And in the main-body part 10 (vacuum cleaner main body 1), the light emitting element 10c is formed in the upper direction of the connection terminals 10u and 10u. That is, the hermetic holding member 90 has not only the connection port 10a but also the opening 90t surrounding the connection terminals 10u and 10u and the light emitting element 10c.

  As described above, the airtight holding member 90 has a diameter larger than that of the connection port 10a and is attached to the outside of the connection port 10a (the outer surface side of the cleaner body 1). The attachment can be attached and detached without removing it from the main body 1). Thereby, when cleaning the vacuum cleaner main body 1 in a stick state, it is possible to switch to the handy state by operating the release button 18. In addition, in this case, since the airtight holding member 90 remains connected to the connection port 10a of the cleaner body 1, the cleaning can be continued with the suction force increased.

  Further, the vacuum cleaner 100 is configured such that the light emitting element 10c is positioned inside the airtight holding member 90 and outside the attachment even when the gap / brush switching nozzle 110 (see FIG. 1) is connected to the connection port 10a. ing. Thereby, it becomes possible to illuminate the floor surface between the airtight holding member 90 and the gap / brush switching nozzle 110, and the cleanability of dark places such as gaps in furniture can be improved.

FIG. 13A shows an irradiation state by the light emitting element when the airtight holding member is attached, and FIG. 13B shows an irradiation state by the light emitting element when the airtight holding member is not attached.
In the comparative example shown in FIG. 13B, the light irradiated from the light emitting element 10c is irradiated to the floor M while being diffused from the connection port 10a. For this reason, when the light is diffused in a high range, the light applied to the floor surface M becomes blurred and dark. On the other hand, in the present embodiment shown in FIG. 13A, the diffusion of the light emitted from the light emitting element 10c is suppressed by the airtight holding member 90, and the flashlight effect by the airtight holding member 90 causes the floor surface. M is spot irradiated. Since the light is thus reduced, the light irradiated to the floor surface M becomes brighter than that in FIG. Therefore, the dust on the floor surface M can be easily identified, and the cleaning performance can be improved.

FIG. 14 is a schematic diagram showing a cooling structure of the storage battery.
As shown in FIG. 14, when the storage battery 3 is attached to the cleaner body 1, the lead-out hole 11 s communicates with the introduction hole 3 e in a state of facing each other. At this time, the communication direction between the lead-out hole 11s and the introduction hole 3e is the front-rear direction. In this state, when the electric blower 40 (see FIG. 6) is driven, the sucked air flows through the motor case portion 11 toward the outlet hole 11s. The air discharged from the outlet hole 11s is supplied to the introduction hole 3e, flows through the gaps 3k1, 3k3, and the like from the front to the rear of the unit cell 3h, and cools the unit cell 3h. Then, the air that flows to the rear of the unit cell 3h flows through the gaps 3k1 and 3k3 from the rear to the front of the unit cell 3h, and flows toward the discharge hole 3f. And the air discharged | emitted from the discharge hole 3f collides with the back surface of the motor case part 11, and is discharged | emitted outside from the clearance gap between the motor case part 11 and the case 3a of the storage battery 3. FIG. In addition, you may make it return the air discharged | emitted from the discharge hole 3f in the motor case part 11, and is discharged | emitted outside from the clearance gap by the side of the cleaner body 1. FIG. Further, a slit may be provided in the storage battery 3 so that air is discharged from the slit.

  In the above description, the case where the partition plate for guiding the air flow is not provided in the storage battery 3 is described as an example. However, the partition for guiding the air in the storage battery 3 to the back side (rear side). A plate may be provided.

  In the above description, a part of the air generated by the suction force by the electric blower 40 (see FIG. 6) is discharged from the exhaust port 16 (see FIG. 3) after cooling the main body substrate 50 (see FIG. 6), The case where the remaining part is used for cooling the storage battery 3 has been described as an example. Note that all the air that has cooled the main body substrate 50 may be used for cooling the storage battery 3. Thereby, the storage battery 3 can be cooled more efficiently. Further, the storage battery 3 may be cooled by dividing the air from the electric blower 40 into the main body substrate 50 and the outlet hole 11s. Thereby, by cooling with the air which does not pass the main body board | substrate 50, the storage battery 3 can be cooled with cooler air, and the cooling efficiency of the storage battery 3 can be improved.

  Moreover, in the vacuum cleaner 100, by making the opening area of the introduction hole 3e larger than the opening area of the extraction hole 11s, it becomes easier to introduce the air derived from the extraction hole 11s into the introduction hole 3e. It can be cooled efficiently.

FIG. 15A is a sectional view showing a modification of the communication structure between the outlet and the inlet, and FIG. 15B is a sectional view showing another modification of the communication structure between the outlet and the inlet.
As shown in FIG. 15 (a), the lead-out hole 11s1 formed in the motor case portion 11 has a convex shape protruding toward the storage battery 3, the introduction hole 3e1 formed in the storage battery 3 has a concave shape, and the lead-out hole 11s1 and the introduction hole 3e1 may be a structure in which concave and convex are fitted. The storage battery 3 side may be convex and the motor case 11 side may be concave. Thereby, the airtightness between the outlet hole 11s1 and the inlet hole 3e1 can be increased, and the air led out from the outlet hole 11s1 can be efficiently introduced into the inlet hole 3e1.

  Further, as shown in FIG. 15B, an annular seal member 19 that surrounds both the entire periphery of the lead-out hole 11s and the entire periphery of the lead-in hole 3e may be provided between the lead-out hole 11s and the lead-in hole 3e. Good. Thereby, the airtightness of the lead-out hole 11s and the introduction hole 3e can be increased, and the air led out from the lead-out hole 11s can be efficiently introduced into the introduction hole 3e.

FIG. 16 is a plan view showing a state in which accessories are connected to the vacuum cleaner.
As shown in FIG. 16, the electric vacuum cleaner 100 is configured so that the extension pipe 300 can be connected in a state where the airtight holding member 90 is connected to the cleaner main body 1. Thus, even if the airtight holding member 90 is connected to the cleaner body 1, the position of the connection port 10a to which the extension pipe 300 is connected does not change. Therefore, the full length L which connected the cleaner main body 1, the extension pipe 300, and the standard suction opening 400 can be restrained short. Thereby, since the position of the standard suction port 400 becomes near at hand, handling becomes favorable and usability can be improved.

  In the vacuum cleaner 100 shown in FIG. 16, even if the extension pipe 300 to which the standard suction port 400 is connected is removed from the stick state to be in a handy state, the airtight holding member 90 is still attached to the cleaner body 1. . Therefore, cleaning can be performed in a state where the suction force is increased.

  In the embodiment of FIG. 16, the case where the extension pipe 300 and the standard suction port 400 are connected to the electric vacuum cleaner 100 has been described as an example, but the embodiment is not limited to this embodiment. For example, the standard suction port 400 can be directly connected to the connection port 10a and used as the handheld vacuum cleaner 100. Thereby, since airtightness with a floor surface is improved by the airtight holding member 90, suction force can be increased. In addition, even if the airtight holding member 90 is connected to the vacuum cleaner main body 1, the position of the connection port 10a to which the standard suction port 400 is connected does not change, so that the total length connecting the cleaner main body 1 and the standard suction port 400 is kept short. Can improve usability.

  As described above, in the vacuum cleaner 100, various accessories (attachments) can be attached and detached while the airtight holding member 90 is attached to the vacuum cleaner main body 1, and cleaning is performed by quickly switching the usage pattern of the cleaning. be able to. Moreover, since the airtight holding member 90 can be left attached to the cleaner body 1, the handy electric vacuum cleaner 100 to which the airtight holding member 90 is attached can perform cleaning while ensuring a high suction force.

Next, the effect of the vacuum cleaner 100 of this embodiment is demonstrated.
In the vacuum cleaner 100 of this embodiment, the electric blower 40 that generates suction force and the cleaner main body 1 that houses the electric blower 40 are provided, and the connection port 10a (suction port) of the vacuum cleaner main body 1 includes: An airtight holding member 90 that secures airtightness between the floor surface (surface to be cleaned) is provided. According to this, since the entire tip 90s of the airtight holding member 90 can be brought into close contact with the floor surface (surface to be cleaned), the suction force can be improved and the usability can be improved.

  Moreover, in this embodiment, the airtight holding member 90 is provided detachably with respect to the cleaner body 1 (refer FIG. 2 and FIG. 3). According to this, even if the airtight holding member 90 is damaged, the airtight holding member 90 can be easily replaced.

  Moreover, in this embodiment, the cleaner body 1 includes the light emitting element 10c that illuminates the floor surface (surface to be cleaned), and the light emitting element 10c is located on the back side of the tip 90s of the airtight holding member 90 (see FIG. 6 and 12). According to this, the floor surface can be spot-irradiated by the flashlight effect of the airtight holding member 90, the dust in the dark place can be easily identified, and the cleaning performance can be improved.

  Moreover, in this embodiment, the cleaner main body 1 can attach or detach an attachment (accessory), and the opening 90t which can attach or detach an attachment in the state with the airtight holding member 90 provided in the cleaner main body 1 (FIG. 12). According to this, since it is not necessary to attach and detach the airtight holding member 90 when attaching and detaching the attachment, the usability of the electric vacuum cleaner 100 can be improved.

  In the present embodiment, the airtight holding member 90 has an annular elastic portion 91a that can be elastically deformed at the tip. According to this, the entire tip 90s of the airtight holding member 90 can be brought into close contact with the floor surface, the suction force can be improved as compared with the case where the tip 90s is not in close contact, and dust can be reliably sucked.

  Moreover, in this embodiment, the electric blower 40 which generate | occur | produces attraction | suction force, the vacuum cleaner main body 1 which accommodates the electric blower 40, and the storage battery 3 provided in the vacuum cleaner main body 1 so that attachment or detachment is possible while supplying electric power to the electric blower 40. And comprising. The cleaner body 1 is formed with a lead-out hole 11s through which exhaust gas is led out from the electric blower 40, and the storage battery 3 is formed with an introduction hole 3e through which the exhaust gas led out from the lead-out hole 11s is introduced. By the way, in the vacuum cleaner provided with the detachable rechargeable battery, the rechargeable battery could not be cooled, and the storage battery was at a high temperature or the power consumption could not be increased. Therefore, in the present embodiment, the storage battery 3 can be cooled using the exhaust gas by connecting the outlet hole 11s and the introduction hole 3e in the vacuum cleaner 100 in which the storage battery 3 is removable. Thereby, it becomes possible to achieve high output while suppressing the temperature rise of the storage battery 3.

  In the present embodiment, the lead-out hole 11s and the introduction hole 3e are formed at positions facing each other. According to this, it is possible to introduce the exhaust (air) led out from the lead-out hole 11s into the introduction hole 3e without forming another flow path (see FIG. 14). Incidentally, in the case where the lead-out hole 11s and the introduction hole 3e do not face each other, the direction of the lead-out hole 11s and the introduction hole 3e is formed sideways, and the lead-out hole 11s and the introduction hole 3e are formed by separate pipes. It is a case to tie.

  In the present embodiment, the storage battery 3 includes a plurality of columnar unit cells 3h (battery cells), and the axial direction of the unit cell 3h is the same as the communication direction S (front-rear direction) in which the lead-out hole 11s communicates with the introduction hole 3e. Direction (see FIG. 14). According to this, exhaust can be flowed along the axial direction of the unit cell 3h, and the unit cell 3h can be efficiently cooled.

  Moreover, in this embodiment, the attachment / detachment direction (front-back direction) of the storage battery 3 with respect to the cleaner main body 1 and the communication direction S (front-back direction) are the same directions (refer FIG. 10). According to this, since the hole is formed in the direction in which the storage battery 3 is pressed, the lead-out hole 11s and the introduction hole 3e can be easily communicated while ensuring airtightness.

  Moreover, in this embodiment, the attachment / detachment direction of the storage battery 3 with respect to the cleaner body 1 is a horizontal direction. According to this, since the self-weight of the storage battery 3 acts in the surface direction (surface formed in the vertical direction and the horizontal direction) between the outlet hole 11s and the inlet hole 3e, the airtightness between the outlet hole 11s and the inlet hole 3e. It is difficult to impair the sex. On the other hand, when the storage battery attachment / detachment direction (attached upward and removed downward) and the communication direction are in the vertical direction, the communication holes act in the direction of separating the communication holes due to the own weight of the storage battery. It becomes difficult to ensure airtightness.

  In the present embodiment, one of the lead-out hole 11s and the introduction hole 3e has a convex shape and the other has a concave shape (see FIG. 15A). According to this, the airtightness between the lead-out hole 11s and the introduction hole 3e can be improved, and the storage battery 3 can be efficiently cooled.

As shown in FIG. 23, the vacuum cleaner 100 is stored in the charging stand 70 with the airtight holding member 90 facing downward in the vertical direction. At this time, the storage battery 3 is configured not to protrude from the line L1 extending from the back surface 72a1. The extension tube 300 is held by the holding portion 72d in a slightly inclined state. Further, the standard suction port 400 is stored (contained) in a state of being in contact with the placement surface 71a.

  The small suction port 600 is stored (accommodated) so that the protrusion 71c2 (see FIG. 17) of the side storage part 71c is inserted into the connecting pipe part 600a connected to the connection port 10a (see FIG. 2). Further, the broom-type suction port 700 is stored (stored) so that the connecting pipe portion (not shown) connected to the connection port 10a (see FIG. 2) is inserted into the hole of the side portion storage portion 72t (see FIG. 17). )

  The small suction port 600 is a simple and simplified version of the standard suction port 400, and is applied to places (such as sofas and bedding) that are mentally resistant to cleaning the same place as the standard suction port 400. it can.

  The broom-type suction port 700 cleans a sash rail, a drawer in which small items are stored, and has a brush body for sweeping dust and a rubber tube for sucking dust. Yes. The tube has a suction port with a diameter that can be flexibly deformed and does not suck small articles. Further, the broom-type suction port includes a plurality of tubes, is arranged linearly in a plan view, and includes a brush body on both sides of the tube.

FIG. 24 is a cross-sectional view showing a connection state between the main body terminal portion and the charging terminal.
As shown in FIG. 24, when the main body terminal portion 17 is fitted to the charging terminal 73, the main body terminal 17d comes into contact with the terminal 73c, and the edge portion 17f of the main body terminal 17d is lowered, so that the terminal 73c is moved backward. Deforms and deforms. Since the terminal 73c has a spring property that biases it forward, the main body terminal 17d and the terminal 73c are kept in contact with each other while the cleaner body 1 is mounted on the charging stand 70. The charging of the storage battery 3 (see FIG. 2) is continued.

  Moreover, since the charging terminal 73 is concavo-convexly fitted with the main body terminal portion 17, for example, even if the user contacts the cleaner main body 1 during charging, the conduction state (contact) between the main body terminal 17d and the terminal 73c. State) will not be released.

  In the charging stand 70 configured as described above, since the charging terminal 73 is formed on the upper surface 72b of the stand portion 72, when the main body terminal portion 17 is attached to the charging terminal 73, the charging terminal 73 is positioned close to the user's eyes. Become. Thereby, it becomes easy to insert the main body terminal portion 17 into the charging terminal 73, and it becomes easy to set the cleaner main body 1 on the charging stand 70.

  In the charging stand 70, the charging terminal 73 is formed on the upper surface 72 b of the stand portion 72. That is, since the charging terminal 73 is formed at a high position from the floor surface, it is difficult for dust to accumulate on the charging terminal 73, and it is possible to reduce dust from adhering to the floor surface.

  Moreover, in the vacuum cleaner 100 (refer FIG. 1) set to the charging stand 70, since the charging terminal 73 is located in the position (position of the electric blower 40 and the storage battery 3) near the gravity center of the vacuum cleaner 100, the vicinity of the gravity center is set. By receiving the charging terminal 73, the cleaner body 1 can be stably held on the charging stand 70 during charging.

  Further, by applying the vacuum cleaner 100 to the charging stand 70, charging can be performed with the dust case 2 removed, so that charging can be performed even while the dust case 2 is being cleaned and dried.

  Further, the charging terminal 73 faces upward, and the main body terminal portion 17 is connected to the charging terminal 73 from above. Thereby, since the dead weight of the vacuum cleaner 100 can be made to act on the charge terminal 73 intensively, the main body terminal part 17 and the charge terminal 73 can be connected reliably.

  Although not shown, the charging stand 70 can be charged with the standard suction port 400 connected to the vacuum cleaner 100.

  The charging stand 70 can be used as a stand for storing the vacuum cleaner 100 even when the power cord 76 (see FIG. 17) is not connected and the storage battery 3 is not charged.

  Moreover, in the state which accommodated the vacuum cleaner 100 in the charging stand 70, since the storage battery 3 is located in an upper end and the lock member 13 is located in the upper end of the storage battery 3, attachment / detachment of the storage battery 3 can be performed easily. it can.

FIG. 25 is a diagram showing a usage pattern when the floor surface is cleaned with a vacuum cleaner in a stick state.
25, the extension pipe 300 and the standard suction port 400 are connected to the vacuum cleaner 100 (with the airtight holding member 90 attached) to make it stick, and the vacuum cleaner 100 protrudes forward from the user so that the floor surface is covered. This is when cleaning. In this case, the user can perform cleaning while moving the vacuum cleaner 100 back and forth while holding the second holding portion 12a2 of the handle portion 12. Although not shown, when cleaning the floor surface with the vacuum cleaner 100 positioned on the left and right sides of the user, the user holds the first grip portion 12a1 of the handle portion 12 while gripping the first grip portion 12a1. The vacuum cleaner 100 can be moved back and forth. Thus, when the user cleans the floor, the position of the handle portion 12 can be changed and cleaned.

FIG. 26 is a diagram showing a usage pattern when a high place is cleaned with a vacuum cleaner in a stick state.
By the way, in the vacuum cleaner (refer to JP, 2006-137165, A) where the center of gravity is on the tip side when the stick is made, when the vacuum cleaner is cleaned at a place higher than the floor surface, Since it is necessary to lift the tip upward, it is easy to put a burden on the wrist.

  Therefore, in the present embodiment, as shown in FIG. 26, the electric blower 40 (see FIG. 6) and the storage battery 3, which are heavy objects of the vacuum cleaner 100, are in a position close to the handle portion 12 (position close to the hand). The center of gravity G of the vacuum cleaner 100 is close to the user's hand. Thereby, even if it is a case where the vacuum cleaner 100 is made into a stick state and the vacuum cleaner 100 is cleaned in a place higher than the floor surface, it becomes easy to clean, and usability can be improved. In FIG. 26, the case where the staircase is cleaned is described as an example, but it is also effective when the vacuum cleaner 100 is lifted to clean the panel of the indoor unit of the air conditioner.

  In addition, when the vacuum cleaner 100 is used in a stick state, when removing dust remaining at the corner (corner) of the staircase, the extension pipe 300 and the standard suction port 400 are removed from the vacuum cleaner 100 to be in a handy state. To do. In this case, since the airtight holding member 90 is still attached to the electric vacuum cleaner 100, cleaning can be performed with the suction force increased, and dust can be prevented from being left unabsorbed.

Next, various applied suction bodies connected to the vacuum cleaner 100 will be described. The above-described electric vacuum cleaner 100 can be cleaned by changing various applied suction bodies (attachments) as accessories.
FIGS. 27A and 27B are cross-sectional views showing a standard suction port to which an opening / closing member is attached, in which FIG. 27A shows a forward time, FIG. 27B shows a time when it hits a wall, and FIG. In FIG. 27, illustration of a motor for driving the rotating brush and a substrate for controlling the rotating brush are omitted.

  As shown in FIG. 27A, the standard suction port 400 includes a suction case 401, a first brush 402 driven by a motor (not shown), and a second brush 403 that is rotated by friction with the floor surface. And is configured.

  The suction case 401 has a space in which the lower surface is opened and the first brush 402 and the second brush 403 are accommodated. The second brush 403 is disposed behind the first brush 402 with a gap.

  An opening / closing member 404 is provided on the front surface of the suction case 401. The opening / closing member 404 has a rotating shaft 404a. The opening / closing member 404 includes a protrusion 404b extending perpendicular to the axial direction of the rotation shaft 404a, and an opening / closing body 404c extending from the rotation shaft 404a in the direction opposite to the protrusion 404b. The protrusion 404b is formed of a hard plate member. The opening / closing body 404c is configured such that a brush portion 404c1 on the front side and a rubber plate 404c2 on the rear side are overlapped in the front-rear direction.

  As shown in FIG. 27A, when the standard suction port 400 is moved forward, the opening / closing body 404c is rotated counterclockwise by the frictional force between the brush portion 404c1 and the floor surface and the suction force of the electric blower 40. It rotates and the lower part of the front surface of the suction case 401 is opened. By opening the opening / closing body 404c in this way, it becomes possible to suck in large dust (dust) located in front of the standard suction port 400.

  As shown in FIG. 27B, when the standard suction port 400 hits the wall, the tip (upper end) of the protrusion 404b first hits the wall. When the standard suction port 400 is further pressed toward the wall, the opening / closing member 404 is rotated clockwise by the pressing force at this time, and the opening / closing body 404c is moved forward. As the opening / closing body 404c moves forward, the opening 401a at the lower front of the suction case 401 is closed. By configuring in this way, it is possible to suck and remove dust near the wall (corner). Further, by moving the standard suction port 400 in the left-right direction, dust near the wall can be more reliably removed.

  As shown in FIG. 27 (c), when the standard suction port 400 is moved backward, the opening / closing body 404c is rotated clockwise by the frictional force between the brush portion 404c1 and the floor surface so that the opening / closing body 404c is directed forward. To work. Thereby, the static pressure in the suction case 401 is increased, so that dust can be reliably sucked.

  Moreover, in the cordless vacuum cleaner 100, the suction force is weaker than that of a vacuum cleaner to which power is supplied from a household outlet. For this reason, in the standard suction port 400, the front surface (opening 401a) of the suction case 401 is opened when moving forward (see FIG. 27A), so that the operation force can be reduced and large dust can be sucked. Further, when the vehicle is moved backward (see FIG. 27C), the opening / closing member 404 is closed and the static pressure is increased, so that, for example, sand dust in the carpet can be sucked firmly. In addition, by configuring the standard suction port 400 to be smaller than the suction port connected to a vacuum cleaner that supplies electric power from a household outlet, it is possible to reduce air leakage from the standard suction port 400 and to equalize the static pressure. It becomes easy to get around.

FIG. 28 is a side view showing a state in which the extension hose is stored.
As shown in FIG. 28, the extension hose 800 is connected to the suction port 802 having a handle 801 at the distal end, the connection port 803 connected to the cleaner body 1 (see FIG. 2) at the proximal end, and the suction port 802. And a bellows tube 804 that connects the mouth 803. In addition, the extension hose 800 in this embodiment can be accommodated in the charging stand 70 in the state which the suction port 802 and the connection port 803 were connected, and the extension hose 800 was made cyclic | annular. By being housed in this way, the extension hose 800 can be stably held on the charging stand 70.

  The extension hose 800 is provided with an electric wire (not shown) that connects the suction port 802 and the connection port 803. The connection port 803 is provided with a connection terminal electrically connected to the cleaner body 1, and the suction port 802 has connection terminals electrically connected to the extension pipe 300, the standard suction port 400, and the small suction port 600. Is provided.

  By connecting the extension hose 800 to the vacuum cleaner main body 1 and using the vacuum cleaner main body 1 with one hand and the handle 801 with the other hand, the position of the small suction port 600 can be freely set. Cleaning is possible while changing. This makes it easier to clean the seats and feet in the vehicle as compared to a vacuum cleaner without an extension hose.

  Further, when the extension hose 800 is stored in the charging stand 70, the handle 801 is configured to face upward, so that the handle 801 can be easily detached from the charging stand 70. Moreover, since the direction of the front end 801a of the handle 801 is set to be obliquely upward, the handle 801 can be gripped in a normal use state when the user stands in front of the charging stand 70, and the extension hose 800 Easy to put on and take off.

The handle portion 120 has a structure in which the first grip portion 12a1 is not provided on the handle portion 12 of the present embodiment. When the extension hose 810 is connected to the cleaner body 1 having such a handle portion 120, the tip of the cleaner body 1 faces downward due to the center of gravity. For this reason, it is necessary to lengthen the length L10 of the extension hose 810 as shown in FIG.

  On the other hand, the vacuum cleaner 100 of this embodiment shown in FIG. 29A includes a handle portion 12 provided with a first grip portion 12a1 in addition to the second grip portion 12a2. For this reason, when the extension hose 800 is connected to the cleaner body 1, the user grips the first grip portion 12 a 1 so that the tip of the cleaner body 1 faces forward. For this reason, as shown to Fig.29 (a), it becomes possible to comprise the length L1 of the extension hose 800 shorter than the case of FIG.29 (b). Thereby, also when accommodating the extension hose 800 in the charging stand 70, the extension hose 800 can be accommodated compactly.

FIG. 30 is a diagram showing another usage pattern of the electric vacuum cleaner.
As shown in FIG. 30, the vacuum cleaner 100 can be used in a state where the extension pipe 300 is connected to the tip of the extension hose 800 and the standard suction port 400 is connected to the tip of the extension tube 300. In this case, the user grasps the floor surface with the standard suction port 400 while holding the first grip portion 12a1 of the handle portion 12 of the cleaner body 1 with one hand and holding the handle 801 of the extension hose 800 with the other hand.
