  The joint cover 38c is attached to the outer surface of the rotation shaft portion 34c so as to cover the outer side of the handle screw 37a.
  As shown in FIG. 8, when the rotary handle 30 is locked, the lock pin 36b is urged toward the lock plate 36a by the lock spring 36c and is inserted into the lock hole 36e. Thereby, when the user is using the vacuum cleaner 100, it can prevent that the rotation handle 30 rotates.
  When the lock button 38a is pushed down in the locked state shown in FIG. 8, the lock release pin 38d formed inside the lock button 38a pushes down the lock pin 36b while receiving the urging force of the lock spring 36c. At this time, as shown in FIG. 9, the lock pin 36 b is pushed down to a position where the lock pin 36 b comes out of the lock hole 36 e. As a result, the unlocked state shown in FIG. 9 is established, and the pivot shaft portions 34c and 34e, the lock plate 36a, and the lock button 38a are pivotable with respect to the right handle joint 35a and the left handle joint 35b. Thus, by depressing the lock button 38a, the rotary handle 30 can be rotated, and the stick type and the handy type can be switched easily and quickly.
FIG. 10A shows the state of the lead wire in the rotary handle in the stick state, and FIG. 10B shows the state of the lead wire in the rotary handle in the handy state.
As shown in FIG. 10A, a lead wire 39 for connecting the operation buttons 31a and 31b and the main board 50 (see FIG. 3) is provided in the rotary handle 30. One end of the lead wire 39 is connected to the operation button 31b and then connected to the operation button 31a. The lead wire 39 is wound around the rotation shaft (handle screw 37a) of the rotation mechanism 33 and passes through the inside of the expansion pipe 20. The main body substrate 50 (see FIG. 3) is connected.
  In the stick state shown in FIG. 10A, the lead wire 39 positioned around the rotation shaft of the rotation mechanism unit 33 is positioned on the outer peripheral side. On the other hand, in the handy state shown in FIG. 10B when the rotary handle 30 is folded, the lead wire 39 positioned around the rotating shaft of the rotating mechanism unit 33 is positioned on the inner peripheral side. By winding the lead wire 39 around the rotating shaft in this way, the bent portion can be prevented from being concentrated at one place with respect to the lead wire 39, and by making the lead wire 39 follow the movement of the rotary handle 30. Disconnection of the lead wire 39 can be prevented.
Next, the handle clamp 25 (clamp mechanism) of the rotary handle 30 will be described with reference to FIGS. 11 and 12. FIG. 11 shows the clamped state of the rotary handle, and FIG. 12 shows the clamped state of the rotary handle.
As shown in FIG. 11, the handle clamp 25 includes a clamp member 25a that clamps the rotary handle 30, an attachment portion 25b that slidably supports the clamp member 25a on the pipe case portion 13 (main body portion 10), and a clamp member. A clamp spring 25c that biases 25a in a direction (rearward) for clamping the rotary handle 30 and a hooking portion 30a provided on the rotary handle 30 are configured.
  The clamp member 25a is formed along the front-rear direction (stretching direction), a finger hook portion 25a1 for hooking a finger to the front end is formed, and a locking portion 25a2 to be locked to the rotary handle 30 is formed at the rear end. .
  The attachment portion 25b is fixed by being screwed into a boss 13d formed on the upper surface of the pipe case portion 13 via a screw 25d.
  The clamp spring 25c urges the clamp member 25a rearward (in the direction in which the rotary handle 30 is clamped), and is configured by, for example, a compression coil spring. Further, the clamp spring 25c is disposed between the wall portion 13e erected on the upper surface of the pipe case portion 13 and the clamp member 25a.
  The hooking portion 30 a is configured in a hole formed in the rotary handle 30. This prevents the user's hand from touching the hook 30a and prevents clothes and the like from being hooked on the hook 30a.
  In the handle clamp 25 configured as described above, as shown in FIG. 11, the clamp member 25a is pressed backward by the elastic return force of the clamp spring 25c when the clamp member 25a is not operated. As a result, the locking portion 25a2 is locked to the hooking portion 30a, whereby the rotary handle 30 is clamped (locked) in a folded state.
  Then, as shown in FIG. 12, by hooking a finger on the finger hooking portion 25a1 and sliding the clamp member 25a forward while receiving the urging force of the clamp spring 25c, the hooking portion of the locking portion 25a2 and the rotary handle 30 is engaged. The locked state with 30a is released. Thereby, the clamp of the rotary handle 30 is released, the rotary handle 30 can be rotated upward, and the vacuum cleaner 100 can be switched from the handy type to the stick type.
  Further, when the vacuum cleaner 100 is used in a stick shape, the clamp member 25a is in the state shown in FIG. When the rotary handle 30 is rotated in the folding direction from this state, the taper 30b formed on the outer surface of the rotary handle 30 comes into contact with the taper 25a3 formed on the locking portion 25a2. Then, when the rotary handle 30 is pushed down, the clamp member 25a slides forward while receiving the urging force of the clamp spring 25c by this push-down force. When the hook portion 30a of the rotary handle 30 gets over the lock portion 25a2, the lock portion 25a2 is locked to the hook portion 30a by the elastic return force of the clamp spring 25c, and the rotary handle 30 is clamped to the main body portion 10. (Fixed).
  In this way, the rotation handle 30 can be prevented from rattling by fixing the rotation handle 30 to the main body 10 with the handle clamp 25. Further, since the lock can be released by sliding the clamp member 25a forward, it is possible to prevent the rotary handle 30 from being unlocked during use.
FIG. 13: is a right view which shows the whole at the time of using a vacuum cleaner as a handy type.
An exhaust port 10a is provided on the right side surface of the main body 10 (motor case unit 11), and an exhaust filter (not shown) is provided inside the exhaust port 10a. In FIG. 13, the case where the exhaust port 10 a is provided only on one side in the left-right direction is described as an example. However, the exhaust port 10 a may be provided on both the left and right sides of the main body unit 10 (motor case unit 11).
  The exhaust port 10 a is formed in a lattice shape that is substantially parallel to the longitudinal direction (front-rear direction) of the motor case portion 11, and is formed in a lower portion of a surface protruding in a circular shape. Thereby, since each opening by a grating | lattice is formed downward, when a user is using as a handy type with the grip part 30t, there exists an effect that the exhaust of the electric blower 40 does not hit a user directly. Moreover, when using as a handy type, the vacuum cleaner main body 1 may be temporarily placed on the floor or the like, but even if liquid such as water is accidentally spilled from above the main body 10, the main body 10 It is possible to prevent liquid from entering the inside of the fan, and to prevent failure of the electric blower 40 and the storage battery 60. Since the user is assumed to be right-handed, the exhaust port 10a is provided on the right side of the cleaner body 1 to prevent the exhaust from directly hitting the user. In addition, an exhaust port on the left side may be provided to handle the case where the user is left-handed. It may be suppressed.
Next, the configuration and operation of the dust case 2 will be described with reference to FIGS. FIG. 14 is an external front view of the dust case. FIG. 14 shows a state viewed from the pipe case 13 (see FIG. 2) side. In the following description of FIGS. 14 to 33, the front-rear direction in the drawing is referred to as the up-down direction.
As shown in FIG. 14, the dust case 2 has a function of separating the dust containing air sucked from the suction body 3 (see FIG. 1) and the gap nozzle 4 (see FIG. 2) into dust and air and collecting the dust. Have
  Moreover, the dust case 2 has the inflow port 149 connected with the inlet tube 14 (refer FIG. 1). The air containing dust flowing into the inflow port 149 is separated into dust and air in the dust case 2 and then discharged from the upper part of the dust case 2.
FIG. 15 is an exploded view of the dust case.
As shown in FIG. 15, the dust case 2 includes an outer cylinder 128, an inner cylinder 129, a dust collection filter 130, a filter case 131 that houses the dust collection filter 130, an upper lid 132, and a bottom lid 133.
  The outer cylinder 128 is a cylinder in which openings are formed on the upper and lower sides, and the lower opening of the outer cylinder 128 is opened and closed by the bottom lid 133.
  The inner cylinder 129 has a structure in which a filter case 131 is provided above the inner cylinder 129 and is integrated with the filter case 131. The filter case 131 integrated with the inner cylinder 129 is inserted through the opening at the top of the outer cylinder 128.
  A dust collecting filter 130 is housed in the filter case 131, and an upper dust cover 2 is attached to the upper part of the outer cylinder 128, thereby forming an integrated dust case 2 as shown in FIG. 14. At this time, the inner cylinder 129 is mounted so as to be substantially concentric with the outer cylinder 128.
16 is a cross-sectional view taken along the line DD of FIG.
As shown in FIG. 16, when the inner cylinder 129 is attached to the outer cylinder 128, a space for separating and collecting dust is formed between the outer cylinder 128 and the inner cylinder 129. Of the space formed by the outer cylinder 128 and the inner cylinder 129, the rear part (the upper part in the figure) is the dust separation part 134 (see FIG. 16), and the front part (the lower part in the figure) is the dust container 135 (see FIG. 16). Become. The dust separation unit 134 is a space that separates dust from the air that carried the dust, and the dust storage unit 135 is a space that collects and stores dust.
  The upper lid 132 is a substantially cylindrical body that is open at the top and bottom, and is formed to be slightly larger than the outer diameter of the filter case receiving portion 128a so as to cover the filter case receiving portion 128a provided on the upper portion of the outer cylinder 128 described later. .
  The dust case 2 has a structure in which the upper lid 132 and the filter case receiving portion 128a can be fixed by rotating the filter case receiving portion 128a from the state where the upper lid 132 is covered. The filter case receiving portion 128a is formed with a notch (not shown) on the inner surface of the upper lid 132 so that the upper lid 132 can be covered only at a predetermined position, and a protrusion (not shown) is formed on the filter case receiving portion 128a. Is formed. When the upper lid 132 is pressed against the outer cylinder 128 side with the notch and the projection aligned, and the upper lid 132 is rotated, the projection enters the space of the notch and the upper lid 132 can be fixed to the outer cylinder 128. In addition, the upper lid 132 is provided with a lock button 119 and is fixed to the cleaner body 1.
  The dust collection filter 130 includes a frame body and a filter member 147 that is folded into a pleat shape within the frame body. The wave direction of the filter member 147 is preferably the vertical direction (gravity acting direction) (see FIG. 15). This is for facilitating the removal of fine dust adhering to the filter member 147. Further, by folding the filter member 147 into a pleat shape, the filter area can be increased, and the pressure loss due to the filter member 147 can be reduced.
  The filter member 147 is, for example, a 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.
  Further, it is desirable that the dust collecting filter 130 can be washed by the user. Further, another filter such as a sponge filter (not shown) may be provided at the front portion of the dust collection filter 130. It is desirable that the sponge filter extends the frame of the dust collection filter 130 to the front side and can be fitted into the frame. It is desirable that the user can wash the sponge filter with water. As a result, the dust collection filter 130 is less likely to be directly soiled by dust, and the careability is improved.
  Further, the dust collection filter 130 is accommodated in a filter case 131 provided on the upper portion of the inner cylinder 129. Therefore, the dust collection filter 130 is located between the upper lid 132 and the filter case 131 described above. In order for all of the air that has passed through the mesh member 136 of the inner cylinder 129 to pass through the dust collection filter 130, it is necessary to press the dust collection filter 130 between the upper lid 132 and the filter case 131. Therefore, the dust collection filter 130 is provided with a packing 148 on the outer periphery for keeping the upper lid 132 and the filter case 131 airtight.
  The packing 148 is formed of rubber members or the like on the upper and lower surfaces of the flange portion 130 a provided on the outer periphery of the dust collection filter 130. When the dust collecting filter 130 is attached to the filter case 131, the lower surface side of the packing 148 and the flange portion 131 a at the top of the filter case 131 are in contact with each other. An airtight surface 132a is provided on the upper portion of the upper lid 132. When the upper lid 132 is covered from above the dust collecting filter 130 as described above, the upper surface side of the packing 148 and the airtight surface 132a come into contact with each other, and the upper lid 132 is fixed by The dust collection filter 130 is pressed between the upper lid 132 and the filter case 131. At this time, as described above, the packing 137 provided at the lower portion of the filter case 131 and the outer cylinder 128 are pressed together so that airtightness can be maintained.
  Furthermore, the upper surface of the dust collection filter 130 is also provided with a packing 130b for airtight maintenance. The packing 130 b is provided so as to protrude above the top surface of the upper lid 132. When the dust case 2 is attached to the cleaner body 1, the airtightness between the cleaner body 1 and the dust case 2 is maintained by the packing 130 b.
The inner cylinder 129 will be described with reference to FIGS. 17, 18, and 19. 17 is a front view of the inner cylinder, FIG. 18 is an exploded view of the inner cylinder, and FIG. 19 is a cross-sectional view taken along line EE in FIG.
As shown in FIG. 17, the inner cylinder 129 includes an upper cylinder 129a having an intake portion 129c in the upper part and a lower cylinder 129b having a diameter larger than that of the upper cylinder 129a in the lower part.
  The side surface (circumferential surface) of the upper cylinder 129a is provided with an intake portion 129c, and is formed by a lattice-like frame body (support frame). In the dust case 2, the vertical frame body (support frame) is used. However, a lattice shape having a frame body (support frame) in the vertical and horizontal directions may be used.
  The suction member 129c has a mesh member 136 stretched over its outer peripheral surface. The mesh member 136 is held on the frame body (support frame) by covering or insert molding. Further, by providing the mesh member 136 in the intake portion 129c, the upper cylinder 129a has a filter function and suppresses the inflow of fine dust into the inner cylinder 129. The mesh member 136 may be polyester or metal (for example, stainless steel).
  The intake portion 129c may be provided with a plurality of small-diameter through-holes (holes of about φ2 mm that can be molded with a mold) instead of the frame body (support frame). Unlike the case where the mesh member 136 is stretched over the frame (support frame), the one provided with such a through hole is effective for strength and tearing of the mesh member 136, and has the advantage that secondary molding is unnecessary. is there.
  A filter case 131 is integrally formed on the upper cylinder 129a. The filter case 131 has a substantially cylindrical shape and is concentric with the upper cylinder 129a. In addition, the filter case 131 has an opening 131b that is open at the top and has a lower portion that communicates with the internal space of the upper cylinder 129a at a substantially central portion. In addition, although the upper cylinder 129a and the filter case 131 are comprised integrally, you may make it a detachable structure.
  A packing 137 is provided at the lower part of the filter case 131. The packing 137 is in contact with the outer cylinder 128 and the filter case 131 in an airtight state when the filter case 131 is housed in a filter case receiving portion 128a of the outer cylinder 128 described later.
  The packing 137 provided in the filter case 131 has a structure (removable structure) in which a ring-shaped rubber member is mounted in a recess in the lower part of the filter case 131. However, it may be possible to remove the packing 137 when cleaning the dust case 2, and the packing 137 may be forgotten. Therefore, even if the filter case 131 and the packing 137 are molded integrally (secondary molding). I do not care.
  As shown in FIG. 18, the lower cylinder 129b of the inner cylinder 129 is configured concentrically with the upper cylinder 129a (see FIG. 7), and is substantially cylindrical and has an upper surface closed. In other words, the lower cylinder 129b has a shape in which a bottom surface is opened and a space 138 (see FIG. 19) is provided.
  Further, the inner cylinder 129 includes an umbrella part 139 in which the shape of the lower cylinder 129b is offset so as to be included in the space 138 (see FIG. 19) of the lower cylinder 129b, and an upper surface of the space 139a formed in the umbrella part 139. And a cylindrical body 140 formed so as to protrude downward from the space 139a.
  The cylindrical body 140 is concentrically formed with the umbrella portion 139, and the bottom surface 140a is closed to form a substantially hemispherical shape. Moreover, the cylindrical body 140 has a tapered shape that tapers toward the bottom surface 140a. By making the cylindrical body 140 taper so as to taper, it becomes a container shape that expands downward together with the tapered taper part at the bottom of the outer cylinder 128 to be described later, so that it is easy for the garbage to fall when it is discarded Become. Note that the diameter of the cylinder 140 may be reduced in order to increase the dust collection volume.
  As described above, the umbrella portion 139 is enclosed in the lower cylinder 129b and provided with a sliding mechanism that slides in the vertical direction, dust can be easily discharged when the garbage is thrown away. The umbrella portion 139 is accommodated in the lower cylinder 129b except when dust is discarded such as when sucked, and slides downward when dust is discarded, thereby pushing out dust in the dust case 2.
  The sliding mechanism includes a bottomed cylindrical spring case 141, a piston portion 142, a stopper 143, a screw 144, and a spring 145 substantially at the center in the umbrella portion 139.
  As shown in FIG. 19, the spring case 141 includes a spring seat 141 a and a spring shaft 141 b, and the outer periphery of the spring case 141 is covered with the cylindrical body 140 described above.
  The piston part 142 is configured to be nested in the spring case 141. The spring shaft 141b is fastened with screws 144 so that the stopper 143 can be fixed. A spring 145 is inserted into the spring case 141 from above and a nested piston portion 142 integrated with the lower cylinder 129b is mounted, and then the stopper 143 is fastened to the spring shaft 141b with a screw 144 or the like.
  With such a structure, a sliding mechanism of the umbrella portion 139 is configured. The stopper 143 slides to a stopper receiving portion 129d provided on the upper surface of the lower cylinder 129b. Therefore, as described above, the sliding distance is less than the height of the space 138 of the lower cylinder 129b, and the height of the stopper 143 is substantially equal to the sliding distance.
  In the dust case 2, the spring case 141 is formed as a separate part, and the umbrella portion 139 is removable. The umbrella part 139 and the spring case 141 are fixed by a lock mechanism (not shown) provided on both sides, and the umbrella part 139 is rotated to be attached and detached. Further, a notch portion 141c is provided on the side surface of the spring case 141, and a protrusion (not shown) provided on the piston portion 142 is fitted into the notch portion 141c to prevent rotation when the umbrella portion 139 is attached or detached. ing. By providing such an attachment / detachment structure of the umbrella portion 139, even when dust enters the lower cylinder 129b, it is possible to remove the dust by removing the umbrella portion 139. In addition, when the inner cylinder 129 is washed, it can be decomposed, so that moisture can be easily removed and care is facilitated. Although the umbrella part 139 and the spring case 141 are separate parts, the umbrella part 139 and the spring case 141 may be integrally formed. In that case, it becomes possible to mold with a mold by making the cylindrical body 140 a separate part.
  The outer cylinder 128 will be described with reference to FIGS. 20 is a front view showing a state in which the bottom cover of the outer cylinder is opened, FIG. 21 is a side view showing a state in which the bottom cover of the outer cylinder is opened, FIG. 22 is a cross-sectional view taken along line FF in FIG. FIG. 24 is a sectional view showing another form of the dust return prevention surface, FIG. 25 is a sectional view showing still another form of the dust return prevention surface, and FIG. 26 is a cross-sectional view of FIG. FIG. 27 is a cross-sectional view showing the operation when throwing away the garbage.
  As shown in FIGS. 20 and 21, the outer cylinder 128 is a substantially cylindrical body that is open at the top and bottom, and is slightly rounder than the outer diameter of the filter case 131 so as to enclose the filter case 131 (see FIG. 15) at the top. A large filter case receiving portion 128a is provided.
  The filter case receiving portion 128a is formed with a flange portion 128b protruding to the outer surface side and the inner surface side. The bottom surface of the above-described upper lid 132 (see FIG. 15) is in contact with the outer surface side of the flange portion 128b, and the outer diameter of the flange portion 128b is substantially equal to the outer diameter of the upper lid 132.
  Further, although not described in detail in the filter case receiving portion 128a, a cutout portion is provided in one place, and is cut out to a size that avoids a protrusion provided on the outer periphery of the filter case 131. Therefore, the inner cylinder 129 to be inserted into the outer cylinder 128 is positioned by aligning the positions of the notches and the protrusions of the filter case 131.
  In addition, the height of the filter case receiving portion 128a is set higher than the sliding distance of the inner cylinder 129 described above. This is because the filter case 131 can be accommodated in the filter case receiving portion 128a when the inner cylinder 129 is mounted with the bottom lid 133 to be described later closed (the umbrella portion 139 (see FIG. 17) protrudes). If the filter case 131 exceeds this height, the inner cylinder 129 is not stable and is difficult to mount.
  The inner diameter of the flange portion 128b is smaller than the outer diameter of the packing 137 (see FIG. 15) provided at the lower portion of the filter case 131 (see FIG. 15), and when the filter case 131 (see FIG. 15) is fixed, the flange portion 128b. A packing 137 is pressed against the upper portion of the plate to keep it airtight.
  A bottom cover 133 is provided at the opening on the opposite side (lower part of the outer cylinder 128) of the filter case receiving portion 128a so as to be opened and closed. Details of the shape of the bottom lid 133 will be described later.
  An inlet 149 and a lid lock mechanism 150 are provided on the side surface of the outer cylinder 128. As shown in FIG. 23, the inflow port 149 is provided on a surface (b) parallel to the horizontal axis (a), and the inflow port outer wall surface 149a is located outside the outer wall surface 128c of the outer cylinder 128. The outer cylinder 128 and the tangent line S2 are connected. Moreover, the opening of the inflow port 149 has a substantially rectangular shape. Therefore, the inflow port outer wall surface 149a is not parallel to the vertical axis (c). In other words, the inlet 149 protrudes outside the outer diameter of the outer cylinder 128. This is to prevent the inner cylinder 129 and the inflow port 149 provided on the concentric axis with the outer cylinder 128 from overlapping each other when viewed from the surface of the inflow port 149.
  By the way, when the inner cylinder 129 faces the front surface (opening side surface) of the inflow port 149, the air including the dust that has flowed in collides with the inner cylinder 129, and the dust separation performance is deteriorated. Further, since the side surface of the inner cylinder 129 has a filter structure in which the mesh member 136 (see FIG. 15) is spanned as described above, problems such as dust sticking to the mesh member 136 occur, and suction force is reduced. There is also a risk of decline.
  Therefore, the arrangement of the inlet 149 as described above is effective for reducing pressure loss and noise. Incidentally, when the inlet 149 having the same opening area as that of the dust case 2 is accommodated within the outer diameter of the outer cylinder 128, the inner cylinder 129 can be faced from the inlet 149, so that the above-described problem occurs. Therefore, it is necessary to reduce the width direction of the inflow port 149, the flow velocity increases, and pressure loss and noise increase. In order to prevent pressure loss and noise from increasing, it is conceivable to change the aspect ratio of the inflow port 149 to ensure a vertically long inflow port 149, but the vertical area (vertical direction in FIG. 20). If the inlet 149 is used, the height of the dust case 2 increases and the size of the dust case 2 increases. The vacuum cleaner 100 is a stick type / handy type vacuum cleaner, a compact vacuum cleaner body 1 is desired, and the dust case 2 needs to be compact. Therefore, by adopting the dust case 2 described above, it is possible to provide the vacuum cleaner 100 in which the cleaner body 1 is made compact.
  In addition, the inflow port 149 is provided on a surface (b-plane) parallel to the horizontal axis center line (b) shown in FIG. 23, and the surface of the inflow port 149 is located on the inner side (lateral) of the outer diameter of the outer cylinder 128. It is located on the axis center line (b) side. Since the introduction pipe 14 (see FIG. 1), which will be described later, is fluidly connected to the outer cylinder 128, the height (by the surface of the inflow port 149 inside the outer diameter of the outer cylinder 128 as described above, the height ( Thus, the vacuum cleaner 100 can be provided in which the vacuum cleaner body 1 is made compact.
  In addition, although the inflow port 149 has been described as an example in the case of being provided on the left side in the illustration of FIG. 20, it may be provided on the right side. Even when the inflow port 149 is provided on the right side, the swirling direction of the inflowing air is just the opposite direction, and there is no influence on the dust separation performance.
  The upper part of the outer cylinder 128 has a cylindrical shape. The outer cylinder 128 is provided with a dust return prevention surface 151 that is substantially horizontally outward substantially in the vertical direction with respect to the central axis of the outer cylinder 128 at a substantially central portion, as surrounded by a broken line 190 in FIG. Further, the outer cylinder 128 has a shape that expands in a taper shape downward from the dust return prevention surface 151. The dust return return surface 151 is enlarged by about 2.5 mm from the upper cylindrical inner peripheral surface of the outer cylinder 128.
  As shown in FIG. 26, when the inner cylinder 129 is attached to the outer cylinder 128, the lower surface of the umbrella part 139 of the inner cylinder 129 is in the cylinder above the outer cylinder 128, and the lower surface of the umbrella part 139 of the inner cylinder 129 ( Dust accumulates below the flange 146 (see FIG. 17), so the dust returns-preventing surface 151 returns from the dust accumulated at the lower portion of the tapered portion of the outer cylinder 128 and the dust container 135 (see FIG. 16). The dust contained in the air is prevented from returning along the inner surface of the outer cylinder 128. As a result, the dust adheres to the mesh member 136 (see FIG. 15) on the side surface of the inner cylinder 128, and the dust from the mesh member 136 is fine. Therefore, it is possible to provide the vacuum cleaner 100 having the dust case 2 in which a reduction in suction force is suppressed.
  Further, by providing the dust return prevention surface 151 and tapering downward from the dust return prevention surface 151, the volume of the outer cylinder 128 can be increased, and more dust can be accumulated. The dust case 2 is inclined about 8 degrees with the central axis of the dust case 2 in the vertical direction.
  In addition, as shown in FIG. 24, the part enclosed by the broken line 190 of FIG. 22 may provide the annular rib 152 in the substantially vertical direction below the dust return return surface 151. The annular rib 152 extends from the upper cylindrical portion and protrudes to the inside of the tapered portion, so that it is possible to prevent dust from flying back along the inner wall of the outer cylinder 128.
  Further, as shown in FIG. 25, the portion surrounded by the broken line 190 in FIG. 22 is a cylindrical shape in the upper part, and the dust return prevention surface that is inclined upward from the substantially central part in the direction perpendicular to the central axis of the dust case 2. 151A may be provided, and the shape may be formed such that the lower side from the dust return prevention surface 151A expands in a tapered shape. By providing such a tilted dust return prevention surface 151A, it is possible to suppress the sticking of dust to the mesh member 136 on the side surface of the inner cylinder 129 and the blow-off of fine dust from the mesh member 136. It is possible to provide the vacuum cleaner 100 having the dust case 2 in which a reduction in suction force is suppressed.
  As shown in FIG. 26, the bottom lid 133 has a dish-like shape with a depth, and is provided with a packing 157 on the outer periphery of the upper surface so that when the bottom lid 133 is closed, airtightness with the bottom of the outer cylinder 128 can be maintained. It has become. Further, the bottom lid 133 has a dish shape to increase the strength. Further, a hook portion 155 (see FIG. 21) for locking the bottom lid 133 to the outer cylinder 128 is provided on a part of the outer periphery of the bottom lid 133. The outer cylinder 128 is provided with a hinge portion 158 (see FIG. 21) provided with a rotating shaft 158a (see FIG. 21) on the opposite side of the hook portion 155.
  As described above, when attaching the dust case 2 to the cleaner body 1, the recess 159 (see FIG. 33) on the bottom surface of the bottom cover 133 is used as the dust case fixing protrusion 13 a (see FIG. 33) of the cleaner body 1. The dust case 2 is pressed against the cleaner body 1 side with the dust case fixing projection 13a as a starting point. Then, the dust case 2 is integrated with the cleaner body 1 by being locked by the lock button 119 (see FIG. 16) on the upper portion of the upper lid 132. Therefore, when the dust case 2 is attached to the cleaner body 1, the lid lock mechanism 150 is hidden on the cleaner body 1 side. This is because when the lid lock mechanism 150 is provided on the opposite side (outside), the lid lock mechanism 150 may be released during cleaning, but the lid lock mechanism 150 should be hidden behind the cleaner body 1 side. Thus, malfunction can be prevented. For example, the vacuum cleaner main body 1 may be brought close to the floor surface horizontally, such as when cleaning a sofa or under a bed in a stick state. At this time, if the lid lock mechanism 150 is provided on the front side, the floor surface There is a possibility that the lid lock mechanism 150 is released in contact with the. The positions of the lid lock mechanism 150 and the hinge portion 158 are not limited to this, and may be provided on the left and right of the cleaner body 1. Providing them on the left and right can prevent the above-described malfunction and eliminates the projection of the hinge portion 158, so that the height in the front-rear direction can be shortened and the size can be reduced.
  Further, the bottom lid 133 has a dish-shaped center protruding from the center, and the center of the bottom cover 133 includes a recessed portion 170 that has a recessed shape from the protruding portion. The indented portion 170 is larger than the spherical sphere radius of the bottom surface 140a of the cylindrical body 140 described above, and the indented portion 170 is in a state where the bottom lid 133 is open (a state perpendicular to the bottom surface of the outer cylinder 128). Thus, a horizontal surface is not formed in the indented portion 170. Further, the depression 170 is made as shallow as possible so that dust does not remain in the depression 170 when the waste is discharged.
  In addition, the depression 170 is formed as a separate body, and is formed using a material such as POM (polyoxymethylene) so as to reduce wear of the member due to friction with the cylinder 140 when the bottom lid 133 is opened and closed. It has been done. In addition, you may shape | mold the hollow part 170 integrally.
  The lid lock mechanism 150 includes a lid lock cover 153, a button 154, and a spring (not shown).
  The lid lock cover 153 includes a rotation shaft and a spring seat (both not shown), and is configured by providing a notch in a part of the side surface and a part of the bottom surface.
  The button 154 includes a knob portion, a claw portion, a shaft hole, and a spring shaft (all not shown). The shaft hole of the button 154 is fitted to the rotation shaft of the lid lock cover 153. When one end of a spring (not shown) is inserted into the spring shaft of the button 154 and the other end is fixed to the spring seat of the lid lock cover 153, the knob of the button 154 and the bottom surface of the button 154 are cut off from the notch on the side of the lid lock cover 153. The nail part protrudes from the notch. The outer cylinder 128 includes a projection and a screw boss (not shown) for aligning the position of the lid lock cover 153, and the lid lock mechanism 150 is configured by fastening the lid lock cover 153 to the outer cylinder 128 with screws. .
  Using the side of the lid lock cover 153 (facing the knob) as a fulcrum, the spring (not shown) is shrunk by picking the knob, the claw is rotated within the movable range, and the spring (not shown) is loosened. Returns to its natural length and the knob returns to the state of protruding from the lid lock cover 153. When the lid locking mechanism 150 is operated with the bottom lid 133 closed, the claw portion of the button 154 is detached from the hook portion 156 provided on the bottom lid 133, and the bottom lid 133 is opened. The claw portion and the hook portion 156 are provided with slopes, and the slopes come into contact with each other by closing the bottom cover 133. Further, when the bottom cover 133 is pushed up, the button 154 obtains a rotational force to obtain a spring (not shown). The claw part gets over the hook part 156 and the bottom cover 133 is closed again.
  In the structure of the dust case 2 including the outer cylinder 128 and the inner cylinder 129 as described above, the inner cylinder 129 is attached to the outer cylinder 128 so that the sliding mechanism provided in the inner cylinder 129 is the lower end of the outer cylinder 128. This is done by opening and closing the bottom lid 133 provided on the front. As shown in FIG. 27, when the bottom lid 133 is opened, the umbrella portion 139 protrudes downward. When the bottom lid 133 is closed, the spring 145 is contracted and the umbrella portion 139 is accommodated in the lower cylinder 129b. Therefore, when the lid locking mechanism 150 of the bottom lid 133 is released when the garbage is thrown away, the umbrella part 139 jumps downward and pushes out dust.
  In such a sliding mechanism, the state in which the spring 145 is close to the natural length is the state in which the umbrella portion 139 protrudes most. As described above, the vertical sliding distance of the umbrella portion 139 is less than the height of the space 138 of the lower cylinder 129b. In other words, the upper surface 139c (see FIG. 18) of the umbrella portion 139 does not exceed the bottom surface 129e (see FIG. 18) of the lower cylinder 129b. This is to prevent dust from being trapped between the bottom surface 129e and the top surface 139c by eliminating a gap as much as possible between the bottom surface 129e of the lower cylinder 129b and the top surface 139c of the umbrella portion 139 when the garbage is discarded. Further, the umbrella portion 139 is provided with a minimum necessary gap that can easily slide in the space 138 in the lower cylinder 129b. Moreover, since the umbrella part 139 is in the dust accommodating part 135, if the gap (gap) between the outer periphery of the umbrella part 139 and the lower cylinder 129b is too small, it is possible that the dust bites into the gap and is difficult to slide. . The dust case 2 is provided with a gap in consideration of the biting of dust, and is provided with a plurality of ribs 139b (see FIG. 18) on the outer periphery of the umbrella portion 139, so that the gap increases when the gap is increased. Reduced. Further, the umbrella portion 139 is provided with a step portion 139d (see FIG. 18), and the step portion 139d and the bottom surface 129e (see FIG. 18) of the lower cylinder 129b are combined (the umbrella portion 139 is in the space 138 of the lower cylinder 129b). In the accommodated state), there is no gap between the lower cylinder 129b and the umbrella portion 139. This suppresses the entry of dust into the gap between the lower cylinder 129b and the inside of the umbrella portion 139 during dust suction. Moreover, the bottom part of the umbrella part 139 is provided with a collar part 146 (see FIG. 18), and the dust part 146 (see FIG. 16) to the dust separation part 134 (see FIG. 16) is provided with the collar part 146. Suppresses the return. In addition, since dust accumulates below the flange portion 146, it is preferable that the dust discharge timing is before the dust exceeds the flange portion 146.
Next, the operation at the time of dumping will be described with reference to FIGS. 26 and 27. FIG.
As shown in FIG. 26, the bottom lid 133 is released by picking a button 154 (see FIG. 20) of the lid lock mechanism 150 provided on the side surface of the dust case 2. That is, the bottom lid 133 includes a hinge portion 158 (see FIG. 21) on the opposite side of the lid lock mechanism 150, and rotates about the rotation shaft 158a (see FIG. 21) of the hinge portion 158, as shown in FIG. The bottom lid 133 is in a substantially vertical state (the top surface of the bottom lid 133 is vertical).
  At the same time as the bottom cover 133 is opened, the urging force of the spring 145 causes the umbrella part 139 and the cylinder 140 to jump downward from the opening at the lower end of the outer cylinder 128. Accordingly, the umbrella portion 139 is positioned closer to the opening of the lower surface of the outer cylinder 128 when the bottom lid 133 is opened than when the bottom lid 133 is closed. By the sliding movement of the umbrella part 139, the collected dust is pushed downward.
  After closing the garbage, when closing the bottom lid 133, the bottom surface 140a of the cylinder 140 that protrudes downward contacts the recess 170 provided in the center of the bottom lid 133, and the umbrella 139 and the cylinder 140 are pushed upward. Since the bottom surface 140a of the cylindrical body 140 and the recess portion 170 are in contact with each other in a spherical shape, the contact area between the bottom surface 140a of the cylindrical body 140 and the recess portion 170 is kept constant even if the angle of the bottom lid 133 is changed by closing the bottom lid 133. Further, since the force is always applied in the vertical direction by bringing the curved surfaces into contact with each other, the umbrella portion 139 fits in the lower cylinder 129b smoothly. Incidentally, when the bottom cover 133 is brought into contact with a flat surface without providing the recessed portion 170, the direction in which the force is applied is perpendicular to the flat surface, so that the umbrella portion 139 is difficult to return vertically and the bottom cover 133 is difficult to close. When the bottom lid 133 is closed to a substantially horizontal state, the hook portion 156 engages with the hook portion 155 (see FIG. 21), and is locked in a state in which airtightness is maintained by the packing 157 provided on the bottom lid 133.
  Next, in the vacuum cleaner 100, the shape and structure of the introduction pipe 14 that guides air containing dust to the dust case 2, which is upstream of the dust case 2, and the air flow will be described with reference to FIGS. 28 to 33. To do. 28 is a perspective view showing the positional relationship between the dust case and the introduction pipe, FIG. 29 is a view showing the flow of air in the pipe case portion, FIG. 30 is a sectional view taken along the line II in FIG. 29, and FIG. 32 is a front view showing the positional relationship, FIG. 32 is a view showing the flow of air inside the dust case, and FIG. 33 is a cross-sectional view showing the airtight structure of the dust case and the cleaner body. In addition, the code | symbol 171 shown in the figure shows dust, and the arrow A shows the flow of air.
  As shown in FIG. 28, the electric vacuum cleaner 100 for both stick type and handy type is a flow path from the suction port 15 at the tip of the vacuum cleaner body 1 to the inlet 149 of the dust case 2 (outer cylinder 128). An introduction pipe 14 is provided. In FIG. 28, each part is omitted from the state where the dust case 2 is attached to the cleaner body 1 shown in FIG.
  The introduction pipe 14 is provided with an inlet pipe outlet 161 that is open at the front and rear and connected to the inlet 15 of the dust case 2 (outer cylinder 128) at the front and the inlet 15 at the rear. The introduction pipe 14 includes straight pipes 160 a and 160 b, the straight pipe 160 a is located on the side surface of the dust case 2, and the straight pipe 160 b is located in front of the bottom cover 133.
  As shown in FIG. 29, the central axis (d) of the dust case 2 is collinear (parallel) with the central axis (not shown) of the cleaner body 1 when viewed from above. As described above, the dust case 2 is located below the straight part (straight line 160a).
  The central axis (e) of the straight portion (straight line 160 a) of the introduction pipe 14 is parallel to the central axis (d) of the dust case 2. The introduction tube 14 has a substantially S-shape, and the suction body 3 (see FIG. 1) and the like are connected to the suction port 15 at the tip (front). Further, the introduction pipe 14 includes a straight pipe 160 a formed from the inlet 149 (see FIG. 20) of the outer cylinder 128 to the bottom of the outer cylinder 128, and the bottom lid 133 along the outer surface of the bottom lid 133. An inclined pipe 160c bent in a direction toward the center of the pipe and a straight pipe 160b extending forward.
  The central axis (to) of the straight pipe 160b is located on the same line as the central axis (d) of the dust case 2 when viewed from above. In other words, the introduction pipe 14 has a pipe shape in which the central axis of the straight pipe 160a and the central axis (f) of the straight pipe 160b having the suction port 15 are parallel, and both the straight pipes 160a and 160b are connected obliquely downward. Although the inclination angle of the oblique pipe 160c that connects the straight pipes 160a and 160b obliquely downward differs depending on the position of the suction port 15, the position (range) of the suction port 15 is within the bottom surface of the dust case 2 (within the outer diameter of the bottom lid 133). ).
  The introduction pipe 14 is housed in the pipe case portion 13 of the cleaner body 1, and the pipe case portion 13 has a shape in which the left side is swollen when viewed from above. The introduction pipe outlet 161 connected to the inlet 149 of the dust case 2 is provided with a packing 162. When the dust case 2 is attached to the cleaner body 1, the packing 162 and the inlet 149 are pressed against each other to maintain airtightness. It is supposed to be.
  The packing 162 uses a rubber member, a non-breathable sponge-like member, or the like to be integrated with the introduction pipe outlet 161 (secondary molding), or the introduction pipe outlet 161 and the pipe case portion 13. The inlet tube outlet 161 and the packing 162 are kept airtight by being fixed so as to be sandwiched between them. The packing 162 may be provided not at the inlet pipe outlet 161 but at the inlet 149 of the dust case 2. However, when the dust case 2 can be washed with water, if the packing 162 is a separate part, the packing 162 is attached. Since there is a risk of forgetting or the like, it is preferable to provide it at the introduction pipe outlet 161 as described above.
  The air sucked from the suction port 15 flows as shown by the arrow A along the shape of the introduction pipe 14. At this time, the dust 171 having a density greater than that of air and having a heavy weight is pushed to the right inner wall surface side (the left inner wall surface side in the drawing) by the inertial force 180 by the slanting pipe 160c, and the right inner wall surface side (the drawing is illustrated). It is conveyed toward the dust case 2 along the left inner wall surface side. Since the right inner wall surface side of the straight pipe 160 a is connected to the right inner wall surface of the inlet 149 provided in the outer cylinder 128, it is connected to the inner wall surface of the outer cylinder 128 in the tangential direction. Therefore, since the dust 171 conveyed along the right inner wall surface of the straight pipe 160a turns on the inner wall surface of the outer cylinder 128 farthest from the outer periphery of the inner cylinder 129, the centrifugal separation performance is improved.
  As shown in FIG. 31, the straight pipe 160a is located above the straight pipe 160b having the suction port 15 as seen from the suction port 15 side (front). Is transferred to the upper side of the inner wall surface of the straight pipe 160 a by the inertial force 180, so that the dust 171 is transferred above the outer cylinder 128. Thereby, the height direction of the inflow port 149 can be used effectively, and the length of the dust separation part 134 (refer FIG. 16) can be used effectively.
  The higher the dust separation unit 134 is (the longer it is in the front-rear direction), the higher the dust separation performance. Therefore, it is possible to provide the vacuum cleaner 100 having the dust case 2 that ensures the centrifugal separation performance while suppressing the height of the dust separation portion 134 (downsizing) by using the bent introduction tube 14 as described above. Can do.
  In addition, providing the bent portion in the introduction pipe 14 leads to the compactness of the cleaner body 1. For example, when cleaning the bottom of a sofa or bed in a stick type, the cleaner body 1 is brought close to the floor surface and the mouthpiece 3 is inserted into a narrow gap. At this time, in the shape in which the introduction pipe extends straight, the cleaner body 1 cannot be brought close to the floor surface unless the introduction pipe is lengthened. Therefore, the front-rear length of the vacuum cleaner body 1 can be shortened by bending the introduction tube 14 as described above, and the compact vacuum cleaner 100 can be provided. By the way, as a method of shortening the front and back length of the vacuum cleaner body 1, it is possible to bring the introduction pipe closer to the floor surface without reducing the diameter of the dust case 2, but the diameter of the dust case 2 is reduced. By doing so, there is a risk that the separation performance, the amount of dust collection will decrease, and even the pressure loss will deteriorate. Therefore, by bending the introduction pipe 14 as described above, the separation performance is improved, the dust case 2 having a large amount of dust collection and low pressure loss, and a compact vacuum cleaner 100 is provided. can do.
  Further, even when the introduction tube 14 extends straight, unlike the electric vacuum cleaner 100, the dust case 2 is provided on the upper portion of the vacuum cleaner main body 1 (above the pipe case portion 13), so that the cleaner main body 1 described above is provided. It is possible to move the mouthpiece 3 close to the floor surface and insert the mouthpiece 3 into a narrow gap. However, since the inlet 149 of the dust case 2 faces upward, the cleaning main body 1 is cleaned with the floor close to the floor surface, or the body of the vacuum cleaner main body 1 is placed above the dust case 2 in a handy state (dust collecting filter). When the operation is stopped by cleaning with the (130 side) facing downward, dust may remain in the introduction pipe 14. In order to solve this problem, there is a product in which a check valve is provided at the inlet 149, but there is a risk that the check valve may increase pressure loss or dust may be caught in the check valve. Therefore, as described above, the dust case 2 is provided on the lower side of the cleaner body 1 and the introduction pipe 14 is bent, so that it is difficult for dust to remain on the inlet 149 side even in various cleaning postures. It is possible to provide a compact vacuum cleaner 100 that suppresses an increase in pressure loss due to the provision of a stop valve or the like and prevents dust from being caught in the check valve.
  Further, as described above, when the vacuum cleaner main body 1 is viewed from above, the left side of the pipe case portion 4 has a bulging shape. In other words, the central axis of the dust case 2 and the central axis of the cleaner body 1 are parallel (on the same line), but the axis of the straight pipe 160a of the introduction pipe 14 is not on the same line of both axes. In this way, by arranging the introduction tube 14 in an asymmetrical arrangement shifted in the left-right direction from the cleaner main body 1 (dust case 2), the cleaner main body 1 can hardly hit the user's body in the stick-type form. When the introduction tube 14 is arranged on the right side (the left side in the figure) as viewed from the front as described above, the left-hand protrusion of the cleaner body 1 is small, so that it is easy for right-handed users to use, and the introduction tube 14 is provided on the left side. When placed, it is easier for left-handed users to use. Switching between the right side and the left side only requires replacement of the outer cylinder 128, the introduction pipe 14, and the pipe case part 13, so that the vacuum cleaner 100 that realizes a universal design with a small number of parts replacement can be provided.
  As shown in FIG. 32, when the user starts driving with the operation button 31 a or the operation button 31 b provided on the rotary handle 30 (see FIGS. 1 and 2), electric power is supplied to the electric blower 40 from the storage battery 60. And the electric blower 40 drives and inhales air. The sucked air flows from the inlet 15 of the inlet pipe 14 through the inlet pipe outlet 161 into the dust case 2 through the inlet 149 (flow 200). At this time, dust is conveyed from the tangent S2 direction (see FIG. 23) of the outer cylinder 128 into the dust case 2 while being pushed by the bent inner wall of the introduction tube 14 (see FIG. 29). The The air containing the dust flowing in becomes a swirl flow, centrifugal force acts on the dust, and the dust and air are separated (flow 201). That is, dust and air are separated by the dust separation unit 134 which is the upper part in the dust storage unit 135. Most of the separated air flows into the inner cylinder 129 from the intake portion 129c provided in the upper cylinder 129a (flow 202). Then, the air passes through the dust trapping filter 130, passes through the upper opening of the upper lid 132, and reaches the electric blower 40 (flow 203). At this time, the fine dust that has passed through the mesh member 136 of the intake portion 129c is collected by the dust filter 130.
  On the other hand, the dust separated by the centrifugal force passes between the outer cylinder 128 and the lower cylinder 129b by gravity and a part of the air flow, and is conveyed into the dust container 135. At this time, since centrifugal force is acting on the dust, the dust turns in the dust container 135 (flow 204). If the vacuum cleaner 100 is continuously used, the dust disposal timing is reached when the dust gradually accumulates and the dust container 135 is full (in a donut shape).
  By the way, the air flowing into the dust container 135 may flow from the vicinity of the outer periphery of the lower cylinder 129b toward the upper cylinder 129a along the shape of the space 139a of the cylinder 140 and the umbrella 139 (flow 205). In order to suppress the return of dust to the upper cylinder 129a due to the air flow, the depth of the umbrella portion 139 is necessary. Since the dust case 2 is provided with a sliding mechanism for pushing out dust to the lower cylinder 129b, the umbrella portion 139 has a sufficient depth. Further, the return of dust to the upper cylinder 129a is further suppressed by the dust return prevention surface 151 (see FIG. 22) provided at the upper end of the tapered portion of the outer cylinder 128.
  When the dust container 135 is full of dust, the waste is discarded. The dust discharge mechanism is the same as described above. Even when the amount of sucked dust is small, the sliding mechanism of the umbrella 139 and the taper of the outer cylinder 128 are used. Depending on the shape, dust can be discharged.
  In addition, providing a mechanism for discharging dust from below the dust case 2 is effective for a vacuum cleaner (rechargeable vacuum cleaner) having a main body terminal 12d behind the dust case 2, and the dust case 2 Can be prevented from adhering to the rear (upper lid 132 side).
Next, the configuration of the dust case attaching / detaching mechanism (lock button) will be described.
As shown in FIG. 33, the pipe case portion 13 includes a dust case fixing protrusion 13 a for fixing the dust case 2, and the motor case portion 11 includes a dust case fixing hole 118 for fixing the dust case 2. ing. The dust case 2 is provided with a lock button 119 urged by a lock button spring 120. By inserting the dust case fixing protrusion 13a into the recess 159 on the bottom surface of the dust case 2 and rotating the dust case fixing protrusion 13a toward the pipe case 13 side from the starting point, the lock button 119 is caught in the dust case fixing hole 118, The dust case 2 is integrated with the cleaner body 1.
  When removing the dust case 2, the lock button 119 is slid forward to disengage the lock button 119 from the dust case fixing hole 118, and the dust case 2 is rotated in the direction opposite to that when the dust case 2 is attached. 159 can be removed from the dust case fixing protrusion 13a.
  As shown in FIG. 33, the bottom surface (back side surface) of the bottom lid 133 is provided with a recess 159 on the pipe case 13 side of the cleaner body 1, and the dust case fixing protrusion 13 a of the cleaner body 1 A recess 159 (see FIG. 3) on the bottom surface of the bottom lid 133 is fitted. The dust case fixing protrusion 13a and the recess 159 are formed with a width in the left-right direction (the direction perpendicular to the paper surface of FIG. 33). Thereby, when attaching the dust case 2 to the cleaner body 1, the dust case 2 is prevented from operating in the rotational direction.
  The airtight surface 112 that partitions the electric blower 40 and the dust case 2 disposed in the main body 10 is provided with a suction part 113 that allows the electric blower 40 and the dust case 2 to communicate with each other. A protective filter 115 is provided in the air flow path of the suction portion 113 to prevent dust from entering the electric blower 40 when the operation is performed with the dust case 2 removed. Can do.
  Further, it is desirable that the protective filter 115 is configured to be detachable from the main body unit 10 and can be washed with water so that it can be cleaned when dirty. Further, the protective filter 115 is fixed to the main body 10 by a protective filter cover 114. It is desirable that the protective filter cover 114 has a lattice shape configured with holes of a size that does not allow a user's finger to touch the electric blower 40 so that the finger does not enter.
  The main body 10 includes an anti-vibration air-tight rubber 116 made of an elastic seal member such as rubber on the upstream side of the electric blower 40, and the anti-vibration air-tight rubber 116 is in close contact with the flat surface on the outer periphery of the protective filter cover 114. Thus, airtightness can be ensured. Moreover, since the vibration-proof airtight rubber 116 is fixed together with the electric blower 40 in the fixed case 11 a, it also plays a role of absorbing rotational vibration generated by driving the electric blower 40.
  By the way, when attaching the dust case 2 to the main body 10, if the dust case 2 is pushed in while being translated from below (horizontal direction), the packing 120 b is turned up, and there is a possibility that the airtightness between the dust case 2 and the suction portion 113 cannot be secured. . Therefore, the dust case 2 is provided with a recess 159, and the pipe case 13 (main body portion 10) is provided with a dust case fixing projection 13a that fits into the recess 159, so that the dust case fixing projection 13a serves as a fulcrum P. Move. Further, the airtight surface 112 is located behind (on the upper side in the drawing) from the rotation tangent S3 of the upper end surface 2s of the dust case 2. When the dust case 2 is pushed in to the maximum, the upper end surface 2 s of the dust case 2 and the airtight surface 112 become parallel, and the packing 130 b comes into contact with the entire periphery of the opening edge of the suction portion 113. The airtight surface 112 of the main body 10 is inclined at a predetermined angle α (for example, 5 degrees) with respect to the vertical direction (the horizontal direction in the figure).
  In addition, the packing 130b has a shape that expands toward the rear (upward in the drawing) in the cross-sectional view shown in FIG. 33, and further has a shape that turns back toward the front (lower in the drawing) at the rear end. By adopting such a shape, the packing 130b is hardly turned over when the dust case 2 is attached or detached. Even if the packing 130b is not strongly pressed against the suction portion 113, the packing 130b is sucked to the suction portion 113 by the suction force when the electric blower 40 is driven, and the dust case 2 and the suction portion 113 are sucked. Airtightness with the part 113 is ensured reliably.
  Thus, in the above-described electric vacuum cleaner 100, the main body portion 10 including the electric blower 40, the elastic pipe 20 attached to the main body portion 10 so as to be extendable and retractable, and the elastic pipe at the distal end portion of the elastic pipe 20 There is provided a cleaner body 1 having a rotary handle 30 attached so as to be rotatable in 20 expansion / contraction directions (front-rear direction). Thereby, since the position of the rotary handle 30 approaches the electric blower 40 of the main body 10, when the vacuum cleaner 100 is used in a handy state, the rotary handle 30 is set to the center of gravity Ga (see FIG. 2) of the vacuum cleaner 100. It can be brought closer, and there is no significant burden on the user's hand. Further, when the vacuum cleaner 100 is used in a stick state, the center of gravity Ga of the vacuum cleaner 100 can be positioned close to the floor surface, so that a large burden is not placed on the user's hand.
  Further, in the vacuum cleaner 100, the rotary handle 30 has grips 30s and 30t around the elongated opening 32, the telescopic pipe 20 is accommodated in the main body 10, and the rotary handle 30 is placed on the telescopic pipe 20 side. In the state of being rotated and folded (in the handy state), the opening 32 is positioned upward of the electric blower 40. Thereby, since the position of the grip part 30t and the gravity center Ga (refer FIG. 2) of the vacuum cleaner 100 can be made to correspond in the front-back direction, when using it in a handy state, a big burden is put on a user's hand. There is nothing.
  In the vacuum cleaner 100, when the telescopic pipe 20 is housed in the main body 10 and the rotary handle 30 is folded, the length of the electric blower 40 in the longitudinal direction (front-rear direction) and the length of the main body substrate 50 (front-rear direction) ) (The length in the longitudinal direction (front-rear direction) of the storage battery 60) is substantially equal to the length in the longitudinal direction of the opening 32 of the rotary handle 30. As a result, the center of gravity Ga (see FIG. 2) of the vacuum cleaner 100 is positioned below (near) the rotary handle 30, so that the vacuum cleaner 100 can be easily held even when it is in a handy form. It becomes easier to clean and improves usability. Further, when the vacuum cleaner 100 is used in a stick-type form, the center of gravity of the vacuum cleaner 100 is not on the floor but on the floor side, so that it can be cleaned without placing a heavy burden on the hand, and is easy to use. improves. In this way, the vacuum cleaner 100 that is easy to use can be realized in either a handy type or a stick type. Moreover, when storing the vacuum cleaner 100, it can be stored in a low height place by using a handy type.
  Further, the lid lock mechanism 150 provided in the dust case 2 is disposed at a position where the lid lock mechanism 150 is hidden when the dust case 2 is attached to the cleaner body 1. Is released, and the dust collected in the dust case 2 can be prevented from being accidentally discharged. In addition, a cleaning brush 172 is detachably provided in the dust case 2, but the cleaning brush 172 is also hidden when the dust case 2 is attached to the cleaner body 1 during operation. It does not come off, and it is not necessary to store the care brush 172 in a different place from the vacuum cleaner 100.
  Further, since the operation direction of the lock button 119 when removing the dust case 2 from the cleaner body 1 is forward (downward in FIG. 33), the dust case 2 can be prevented from being detached from the cleaner body 1 during operation. .
  Next, the structure of the charging stand 70 is demonstrated with reference to FIG. 34 thru | or FIG. 34 is an external perspective view of the charging stand, FIG. 35 is an exploded perspective view showing the charging stand, FIG. 36 is a perspective view showing the charging terminal of the charging stand, FIG. 37 is a perspective view showing the main body terminal of the vacuum cleaner, and FIG. Is a cross-sectional view showing the connection state of the charging terminal and the body terminal, FIG. 39 is a perspective view when the vacuum cleaner is attached to the charging stand in a handy state, and FIG. 40 is when the vacuum cleaner is attached to the charging stand in a stick state FIG.
  As shown in FIG. 34, the charging stand 70 includes a base portion 71, a stand portion 72, and a charging stand terminal portion 73.
  The base 71 has a substantially rectangular mounting surface 71a on which the suction body 3 (see FIG. 1) is mounted. Moreover, the base part 71 has the extension part 71b extended in the back in the center of the width direction (left-right direction). Application suction body fixing projections 71c and 71c for detachably attaching the application mouthpiece 5 (see FIG. 53) and the like are provided on the left and right sides of the extending portion 71b. When the applied mouthpiece 5 is attached, it can be stored by being inserted into the applied mouthpiece fixing protrusion 71c.
  The stand portion 72 extends upward in the vertical direction (vertical direction) from the rear end portion of the extending portion 71b. In addition, the stand part 72 is formed such that the upper part from the center in the vertical direction is thicker in the front-rear direction than the lower part.
  The charging terminal 73c is a terminal that charges the storage battery 60 by being electrically connected to the cleaner body 1, and is formed to protrude upward from the upper surface 72a.
  As shown in FIG. 35, the stand part 72 is detachable from the base part 71. Note that the base portion 71 and the stand portion 72 may not be detachable, but are desirably detachable in order to improve storage and packing properties.
  The base portion 71 includes a power cord 76 on the rear surface and has a charging board 74 inside. In addition, a weight 75 is provided inside the base portion 71, and the charging stand 70 is unlikely to fall down when the electric vacuum cleaner 100 is attached to the charging stand 70.
  A charging stand terminal portion 73 is provided on the upper surface 72a of the stand portion 72 so that the storage battery 60 can be charged by being electrically connected to a main body terminal portion 12a provided in the storage battery case portion 12 of the cleaner body 1 to be described later. It has become.
  The stand part 72 is provided with a connection pin 72b, and the base part 71 is provided with a connection terminal 71d for receiving the connection pin 72b. The base part 71 and the stand part 72 are electrically connected. In addition, a recess 72 c for escaping the protruding portion of the lock button 119 is formed on the upper front surface of the stand portion 72.
  As shown in FIG. 36, the charging base terminal portion 73 has a substantially rectangular parallelepiped shaped terminal base 73 a that protrudes upward from the upper surface 72 a of the stand portion 72. The terminal block 73a is elongated in the left-right direction. The terminal block 73a is formed with concave portions 73b and 73b having a substantially rectangular parallelepiped shape that are cut out so that the front surface and the upper surface are open at both left and right ends. A charging terminal 73c is provided in each recess 73b. The charging terminal 73c is screwed inside the stand portion 72.
  The terminal block 73a is formed with concave portions 73d and 73d having a substantially rectangular parallelepiped shape that are notched so that the front surface and the upper surface are opened between the charging terminal 73c and the charging terminal 73c.
  The charging terminal 73c is formed by bending an elongated metal plate, and is disposed so as to bend and deform in the front-rear direction in the recess 73b. The charging terminal 73c is electrically connected to the connection pin 72b described above via a lead wire (not shown).
  On the other hand, as shown in FIG. 37, the storage battery case portion 12 of the cleaner body 1 is provided with a main body terminal portion 12a. FIG. 37 illustrates a state in which the main body terminal portion 12a is viewed from the dust case 2 side. The main body terminal portion 12a includes a terminal case 12b, and the terminal case 12b protrudes from the storage battery case portion 12 and is long in the left-right direction.
  A fitting recess 12c into which the terminal block 73a of the charging stand 70 is fitted is formed on the lower surface of the terminal case 12b. A body terminal 12d connected to the charging terminal 73c of the charging base 70 is disposed in the fitting recess 12c. The main body terminal 12d is electrically connected to the storage battery 60 via a lead wire in the storage battery case section 12. Further, in the fitting recess 12c, a fitting protrusion 12e that fits into the recess 73d (see FIG. 36) of the charging base 70 is formed.
  When charging the storage battery 60 of the vacuum cleaner main body 1, the vacuum cleaner main body 1 is lowered downward from the upper position of the charging stand 70, whereby the charging stand terminal portion 73 provided on the upper surface 72 a of the stand portion 72. Is fitted into the fitting recess 12c of the cleaner body 1.
  As shown in FIG. 38, when the main body terminal portion 12 is fitted to the charging base terminal portion 73, the main body terminal 12 d comes into contact with the charging terminal 73 c, and the edge portion 12 f of the main body terminal 12 d is lowered to charge the charging terminal. 73c is bent backward and deformed. Since the charging terminal 73c has a spring property that biases it forward, the main body terminal 12d and the charging terminal 73c are in contact with each other while the cleaner body 1 is mounted on the charging stand 70. The charge to the storage battery 60 is continued.
  Moreover, since the charging stand terminal part 73 has uneven | corrugated fitting with the main body terminal part 12, even if a user contacts the cleaner main body 1 during charge, for example, the electrical connection state of the main body terminal 12d and the charging terminal 73c (Contact state) will not be released.
  In the charging stand 70 configured as described above, since the charging stand terminal portion 73 is formed on the upper surface 72a of the stand portion 72, when the charging stand terminal portion 73 and the main body terminal portion 12 are combined, It becomes a near position, it becomes easy to insert the main body terminal part 12 in the charging stand terminal part 73, and it becomes easy to set the cleaner main body 1 to the charging stand 70.
  In the charging stand 70, the charging stand terminal portion 73 is formed on the upper surface 72 a of the stand portion 72. That is, since the charging stand terminal portion 73 is formed at a high position from the floor surface, it is difficult for dust to accumulate on the charging stand terminal portion 73, and it is also possible to reduce the adhesion of dust rising from the floor surface.
  Moreover, in the vacuum cleaner 100 set to the charging stand 70, since the charging stand terminal part 73 is located in the position (position of the electric blower 40 and the storage battery 60) near the gravity center Ga (refer FIG. 2) of the vacuum cleaner 100, When the charging stand terminal portion 73 receives the vicinity of the center of gravity Ga, the cleaner body 1 can be stably held on the charging stand 70 during charging.
  Moreover, in the charging stand 70, when charging in the state which connected the suction body 3 to the vacuum cleaner 100, since it can be supported by the mounting surface 71a of the base part 71, the vacuum cleaner 100 is connected to the charging base terminal part 73 and the suction mouth. The body 3 can be supported at two locations, and the electric vacuum cleaner 100 can be stably held on the charging stand 70.
  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.
  As shown in FIG. 39, the vacuum cleaner 100 can be charged in a handy state, and as shown in FIG. 40, the vacuum cleaner 100 can be charged in a stick state. Thus, the vacuum cleaner 100 can be set on the charging stand 70 in either the handy state or the stick state. At this time, by mounting the suction body 3 and setting the vacuum cleaner 100, the lower surface of the suction body 3 is supported by the mounting surface 71 a of the base portion 71, so that the vacuum cleaner 100 is supported more stably. can do.
  Further, since the charging base terminal portion 73 is formed at a high position from the floor surface of the upper surface 72a of the stand portion 72, as shown in FIG. 39, the applied suction body 5 is held in the charging base 70, When attaching the vacuum cleaner 100 to the charging stand 70, the vacuum cleaner 100 is prevented from coming into contact with the applied mouthpiece 5, that is, the vacuum cleaner 100 first comes into contact with the stand portion 72, and the applied mouthpiece 5 Can be prevented from falling off the applied suction body fixing projection 71c.
  Further, the charging stand 70 can be used as a stand for storing the cleaner body 1 even when the power cord 76 is not connected and the storage battery 60 is not charged.
  The vacuum cleaner body 1 is provided with a mouthpiece 3 and a charging stand 70 that are detachable. The vacuum cleaner 100 is a rechargeable vacuum cleaner that charges the storage battery 60 at the charging stand 70 and is used as a power source. The vacuum cleaner body 1 includes a power cord and is used as an AC vacuum cleaner. May be.
  Next, the self-supporting structure of the vacuum cleaner 100 will be described with reference to FIGS. 41 and 42. FIG. 41 is a cross-sectional view showing the mouthpiece, and FIG. 42 is a side view when the vacuum cleaner is self-supported in a handy state.
  As shown in FIG. 41, the mouthpiece 3 includes a mouthpiece case 3a and a mouthpiece joint 3b.
  In the suction case 3a, a suction chamber Q having an opening is formed on the lower surface (the surface facing the cleaning surface). The suction chamber Q is provided with a first rotary cleaning body 3c and a second rotary cleaning body 3d.
  The 1st rotation cleaning body 3c rotates by the drive force of a motor (not shown), and is rotatably supported by the suction case 3a. The second rotary cleaning body 3d has a brush whose diameter is smaller than the diameter of the first rotary cleaning body 3c, and is disposed behind the first rotary cleaning body 3c. Further, the suction case 3a is provided with rollers 3e, 3f for supporting the suction case 3a in parallel with the floor surface behind the second rotary cleaning body 3d.
  The inlet joint 3b includes a first connection pipe 3g that is rotatably connected to the inlet case 3a in the front-rear direction, and a second connection that is rotatably connected to the first connection pipe 3g in the left-right direction. A tube 3h.
  The first connecting pipe 3g is configured to be rotatable from a substantially parallel state to a substantially vertical state (up and down direction) with respect to the floor surface (cleaning surface). That is, by rotating the first connection pipe 3g with respect to the suction case 3a with the shaft 3i as a fulcrum, the second connection pipe 3h is rotated between a state substantially parallel to the floor surface and a state substantially vertical. be able to.
  The second connection pipe 3h is configured to be rotatable in the left-right direction (the vertical direction in FIG. 41) with respect to the first connection pipe 3g. Thereby, for example, the main body part 10 can be tilted toward a state substantially parallel to the floor surface from a state in which the main body part 10 is substantially perpendicular to the floor surface.
  The second connection pipe 3h is provided with a power supply terminal 3j that receives power from the storage battery 60. In addition, a connecting pipe 3k connected to the suction port 15 of the cleaner body 1 is formed in the second connecting pipe 3h.
  Further, the second connecting pipe 3h is formed with a protruding portion 3m that protrudes forward in the axial direction of the connecting pipe 3k at the tip. Further, on the upper surface of the mouthpiece case 3a, a contact surface 3n with which the tip of the projection 3m contacts is formed.
  As indicated by the phantom line in FIG. 41, when the suction joint 3b rises forward, the tip of the projection 3m abuts against the contact surface 3n, thereby restricting the forward rotation of the suction joint 3b. Is done.
  As shown in FIG. 42, in the vacuum cleaner 100, when the rotation of the suction joint 3b is restricted, the vacuum cleaner 100 is placed on a vertical line (g) passing through the shaft 3i of the suction joint 3b (first connection pipe 3g). The center of gravity Ga of the main body 1 is located. Thereby, the vacuum cleaner 100 can be made independent.
  Note that whether or not the vacuum cleaner 100 can be made independent depends on the width of the suction case 3a of the suction body 3 in the front-rear direction, and is not limited by the positions of the shaft 3i and the center of gravity Ga.
  Next, the futon inlet will be described with reference to FIGS. 43 is a side view showing the futon inlet, FIG. 44 is a bottom view showing the futon inlet, FIG. 45 is a sectional view showing the futon inlet when the joint is laid down, and FIG. 46 is a sectional view showing the futon inlet when the joint is erected. 47 is a side view showing the handy vacuum cleaner with the futon suction port attached, and FIG. 48 is a side view showing the stick type vacuum cleaner with the futon suction port attached.
  As shown in FIG. 43, the futon inlet 6 includes an inlet body 6a, a rotating body 6b, and a joint 6c.
  The mouthpiece main body 6a has a main body case 6d in which the rotating body 6b is accommodated, and a connecting portion 6e in which a joint 6c is rotatably connected to the upper surface of the main body case 6d. Further, the main body case 6d is positioned at the intermediate portion 6f that extends linearly in the front-rear direction, the front curved portion 6g that is positioned in front of the intermediate portion 6f and curves upward, and the rear of the intermediate portion 6f. And a rear curved portion 6h that curves upward. The main body case 6d is formed symmetrically with respect to the center portion ST1 in the front-rear direction.
  In the rotating body 6b, a part of the rotating body 6b (an area smaller than a semicircle) protrudes downward from the lower surface 6i of the main body case 6d. A plurality of rotating bodies 6b are formed in the front-rear direction. In addition, although the case where the three rotating bodies 6b are provided is described as an example, the number is not limited to three, and may be four or more or two or less. In addition, the three rotators 6b are disposed rearward with respect to the central portion ST1.
  As shown in FIG. 44, the main body case 6d has a horizontally long substantially rectangular shape in plan view, and a horizontally long substantially rectangular opening 6j that is slightly smaller than the main body case 6d is formed on the lower surface 6i of the main body case 6d. Yes.
  The rotating body 6b extends from one end of the opening 6j in the left-right direction to the other end. Further, on the rotating body 6b, plate-like blade portions 6k are formed so as to protrude in a plurality of directions, and the blades are arranged in different directions in the axial direction.
  The futon inlet 6 is configured so that the whole can be washed. For this reason, holes 6v for draining water are formed at a plurality of locations around the opening 6j on the lower surface of the main body case 6d.
  As shown in FIG. 45, the lower surface 6m (the front portion of the lower surface of the suction port body 6a) of the front curved portion 6g of the main body case 6d is formed to warp upward from the opening 6j (the lower surface of the intermediate portion 6f). Yes. Further, the front end (front end) P10 of the lower surface 6m is located above the upper end of the rotating body 6b.
  The lower surface 6n of the rear curved portion 6h of the main body case 6d (the rear portion of the lower surface of the inlet body 6a) is formed to warp upward from the opening 6j (the lower surface of the intermediate portion 6f). Further, the front end (rear end) P20 of the lower surface 6n is located above the upper end of the rotating body 6b.
  A bearing portion 6q that rotatably supports the rotation shaft 6p of the joint 6c is formed in the connection portion 6e of the suction mouth body 6a. The rotating shaft 6p is formed with a contact portion 6u that contacts the opening edge 6t of the connecting portion 6e when the joint 6c is rotated upward. Further, the rotating shaft 6p is formed with a contact portion 6s that contacts the opening edge 6r of the connecting portion 6e when the joint 6c is rotated downward.
  The drain holes 6v are formed at the lower end of the front curved portion 6g and the lower end of the rear curved portion 6h so that water drainage is good.
  Thereby, in the futon suction port 6, when the joint 6c is laid on the floor surface (surface to be cleaned), as shown in FIG. 45, the lower surface (surface on which the opening 6j is formed) of the suction body 6a. It is configured to be γ1 (for example, 15 degrees). When the angle is smaller than γ1 (for example, less than 15 degrees), the front portion of the mouthpiece body 6a is likely to rise when the futon mouthpiece 6 is retracted.
  As shown in FIG. 46, in the futon suction port 6, when the joint 6c is erected most away from the floor surface (surface to be cleaned), the lower surface (surface on which the opening 6j is formed) of the suction body 6a. It is configured to be γ2 (for example, 50 degrees). If the angle is larger than γ2 (for example, more than 50 degrees), it is easy to slip into the futon and the smooth operation of the futon inlet 6 is hindered.
  As shown in FIG. 47, by setting the angle with respect to the lower surface of the mouthpiece main body 6a to γ1, the dust case 2 and the main body 10 do not come into contact with each other when the cleaner body 1 is used as a handy type. The vacuum cleaner body 1 can be moved smoothly back and forth.
  As shown in FIG. 48, by setting the angle with respect to the lower surface of the mouthpiece main body 6a to γ2, it is possible to prevent the force to go into the futon from acting strongly, and the futon inlet 6 can be moved smoothly back and forth. .
  Thus, in the futon suction port 6, the lower surface 6m of the sucking body 6a is warped upward from the opening 6j. Therefore, when the futon suction port 6 is advanced, the lower surface 6m wrinkles the surface of the futon. Can get over the surface irregularities. Further, since the lower surface 6n of the mouthpiece body 6a is also warped upward from the opening 6j, the lower surface 6n can wrinkle the surface of the futon and overcome the irregularities on the surface of the futon even when the futon suction port 6 is retracted. Can do. Thereby, it can suppress that the futon inlet 6 is caught in the futon. Moreover, even if it applies to the rechargeable electric vacuum cleaner 100 having a weak suction force, it can be sucked firmly.
  Moreover, in the futon inlet 6, since the joint 6c which rotates in the front-back direction is provided in the upper surface of the inlet main body 6a, the opening 6j which is the inlet of the futon inlet 6 can be reliably directed to the futon.
  Moreover, in the futon suction port 6, the opening 6j which is the suction port of the futon suction port 6 can be reliably directed to the futon because the joint 6c rotates in the range of 15 degrees to 50 degrees with respect to the lower surface.
  Moreover, in the futon suction port 6, since the rotating shaft 6p of the joint 6c is disposed rearward of the center part ST1 (see FIG. 43) in the front-rear direction of the sucking body 6a, when the futon suction port 6 is advanced. The futon inlet 6 is less likely to be fitted into the futon, and the futon inlet 6 can be moved smoothly.
Next, a rotating brush 80 that is rotatably attached to the cleaner body 1 will be described with reference to FIGS. 49 to 51. 49 is a perspective view showing the storage state of the rotary brush, FIG. 50 is a perspective view showing the use state of the rotary brush, and FIG. 51 is a side view showing the handy vacuum cleaner when the rotary brush is used.
As shown in FIG. 49, the rotary brush 80 includes a rotary brush portion 81 that is rotatably supported by the suction port 15 at the front end of the cleaner body 1, and a fixed brush portion 82.
  The rotating brush portion 81 includes a rotating base 81a and a brush portion 81b implanted in the rotating base 81a.
  The rotating base 81a has a right side portion 81a1 located on the right side of the suction port 15, a left side portion 81a2 located on the left side of the suction port 15, and a lower side portion 81a3 located below the suction port 15 in the stored state. ing. And each edge part of the right side part 81a1 and the left side part 81a2 is rotatably supported by the outer surface of the pipe case part 13. As shown in FIG. Further, the right side portion 81a1 and the left side portion 81a2 are formed so that the width in the front-rear direction increases toward the lower side portion 81a3.
  The brush portion 81b is formed on the right side portion 81a1, the left side portion 81a2, and the lower side portion 81a3 so as to face rearward. Further, the planting direction of the brush portion 81 b is parallel to the axial direction of the suction port 15.
  The fixed brush portion 82 includes a fixed base 82a that is fixed to the pipe case portion 13 and a brush portion 82b that is implanted in the fixed base 82a. Further, the fixed brush portion 82 is disposed between the pipe case portion 13 and the rotating brush portion 81. The brush portion 82b is formed forward and downward with respect to the fixed base 82a.
  As shown in FIG. 50, when the rotating brush portion 81 is rotated, the brush portion 81b is rotated from the rear side to the front side and is inclined downward. At this time, the plate-like portion 81a4 formed on the lower side portion 81a3 is brought into contact with the contact surface 15a (see FIG. 49) formed above the suction port 15, so that the rotation operation of the rotary brush portion 81 is restricted. The
  Thus, by making the rotary brush 80 in use, a closed space can be configured by surrounding the entire periphery of the suction port 15 with the brush portions 81b and 82b on the four sides, so that the suction performance can be improved.
  As shown in FIG. 51, when the cleaner body 1 is used as a handy type, the tips of the brush portions 81b and 82b are made to be flat cleaning surfaces by rotating the rotating brush 80 to bring the brush to the cleaning surface side. It can be contacted. Thereby, the clearance gap between cleaning surfaces can be reduced, suction performance can be improved, and it can clean without damaging a cleaning surface.
  In addition, as shown in FIG. 52, in the vacuum cleaner 100 having the suction body 3, the floor surface under the bed or the sofa is set by using the stick state and putting the vacuum cleaner body 1 in the sleeping state. It becomes possible to clean.
  Further, as shown in FIG. 53, an applied suction body 5 may be attached separately from the suction body 3. The applied suction body 5 is used by being attached to the suction opening 15 so that the tip of the applied suction body 5 is smaller than the distal end of the suction body 3 so that the narrow area where the suction body 3 does not enter can be cleaned. Is desirable. Moreover, in order to clean a high place which cannot reach with a handy type | mold, it is desirable that it is a structure which can be expanded-contracted.
  By the way, in the case where the dust case is arranged on the upper side of the pipe case part, when the operation is stopped when the upper part (hand side) of the dust case is directed downward, the dust in the dust case flows backward to the pipe case part. There is a fear. In the vacuum cleaner having such a configuration, it is necessary to provide a backflow prevention valve at the boundary between the dust case and the pipe case portion in order to prevent backflow. On the other hand, when the applied suction body 5 is attached to the vacuum cleaner 100 and the upper part of the dust case 2 (on the dust collecting filter 130 side) faces downward, the dust case is placed below the pipe case part 13. Therefore, even if the operation is stopped in the state shown in FIG. 53, the dust collected in the dust case 2 does not flow backward to the pipe case 13 side. Even if the operation is stopped with the lower portion of the dust case 2 facing downward, the dust collected in the dust case 2 does not flow back to the pipe case 13 side. Thus, the backflow from the dust case 2 to the pipe case part 13 can be prevented without providing a backflow prevention valve.
  In addition, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning of this invention, it can change variously. For example, the rotation mechanism unit 33 of the rotary handle 30 is not limited to the two forms of the stick state shown in FIG. 1 and the handy state shown in FIG. 2, but can be used in an intermediate state between the handy state and the stick state. May be. Such a configuration can be dealt with by increasing the number of lock holes 36e formed in the lock plate 36a shown in FIG.
  The telescopic pipe 20 has a hollow pipe shape because the lead wires for connection between the operation buttons 31a and 31b of the rotary handle 30 and the main body substrate 50 are housed inside, but this is not restrictive. By arranging the operation button on the main body part 10 so that the lead wire is located outside, it is not necessary to make the elastic pipe 20 into a pipe shape, as long as it can expand and contract in combination with the pipe case part 13, It may be simply a bar shape. Moreover, although the main-body part 10, the expansion-contraction pipe 20, the rotation mechanism part 33, and the rotation handle 30 are described in this order, it is not this limitation. For example, a mechanism in which the main body portion, the rotation mechanism portion, the expansion and contraction pipe, and the rotation handle are arranged in this order, the expansion and contraction pipe 20 is housed in the rotation handle, and is rotated with respect to the main body portion.
