The left handle joint 35b is fixed to the right handle joint 35a, and is positioned at a position facing the lock pin 36b, and is formed with a circular through hole 35i. In addition, at the left handle joint 35b, which is tied to the center in the radial direction, a handle screw for inserting the handle screw 37a is formed Through hole 35j. In addition, a screw insertion hole 35k is formed at the left handle joint 35b at a position facing the screw boss 35f.

The lock plate 36a is formed by a circular metal plate, and a hole 36d is formed at the center portion in the radial direction. In addition, at the locking plate 36a, a locking hole 36e that allows the locking pin 36d to freely advance and retract is formed at the outer peripheral side of the hole 36d. In addition, cutouts 36f and 36f are formed so as to perform positioning in the direction of the front and back surfaces of the locking plate 36a and restrict the rotation operation.

The lock pin 36b is supported by the rotation shaft portion 34e and can move freely in the left-right direction (the rotation shaft direction of the rotation handle 30). The lock pin 36b is pushed toward the lock hole 36e side of the lock plate 36a by the lock spring 36c.

The handle screw 37a is sequentially inserted into the handle screw insertion hole 34d of the handle body portion 34a, the handle screw insertion portion 35e of the right handle joint 35a, the handle screw insertion hole 35j of the left handle joint 35b, and the hole 36d and The handle screw is inserted into the through hole 34f and then screwed with the handle nut 37b.

The lock button 38a is supported at the rotation shaft portion 34e of the handle cover 34b so as to be freely depressible. A lock release pin 38d is formed inside the lock button 38a at a position facing the lock hole 34g (refer to FIG. 8).

The lock spring 38b is interposed between the rotation shaft portion 34e and the lock button 38a, and is pressed in a direction (left direction in the figure) that pushes the lock button 38a upward.

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, in a state where the rotating handle 30 is being locked, the locking pin 36b is pushed toward the locking plate 36a side by the locking spring 36c and is inserted into the locking hole 36e in. With this, it is possible to prevent the rotating handle 30 from rotating when the user is using the electric vacuum cleaner 100.

In the locked state shown in FIG. 8, if the lock button 38a is pressed, the lock release pin 38d formed on the inner side of the lock button 38a is subjected to the pushing force of the lock spring 36c The locking pin 36b is pressed down on one side. At this time, as shown in FIG. 9, the locking pin 36b is pressed all the way to the position where it is pulled out from the locking hole 36e. By this, it becomes the unlocked state shown in FIG. 9, and the rotation shaft portions 34c, 34e, the lock plate 36a, and the lock button 38a become rotatable relative to the right handle joint 35a and the left handle joint 35b status. In this way, by pressing the lock button 38a, the rotary handle 30 can be rotated, and the upright type and the handheld type can be easily and quickly switched.

FIG. 10(a) is the state of the wire in the rotating handle in the upright state, and FIG. 10(b) is the state of the wire in the rotating handle in the hand-held state.

As shown in FIG. 10(a), in the rotary handle 30, a wire 39 is provided to connect the operation buttons 31a, 31b and the body substrate 50 (refer to FIG. 3). This wire 39 is connected to the operation button 31a after one end is connected to the operation button 31b, and is rotated The rotating shaft (handle screw 37a) of the rotating mechanism portion 33 is wound around once, and then passes through the telescopic tube 20 to be connected to the main body substrate 50 (refer to FIG. 3).

In the upright state shown in FIG. 10(a), the wire 39 positioned around the rotation axis of the rotation mechanism portion 33 is positioned at the outer peripheral side. On the other hand, in the hand-held state shown in FIG. 10(b) where the rotation handle 30 is folded, the wire 39 positioned around the rotation axis of the rotation mechanism portion 33 is positioned at the inner periphery side. By winding the wire 39 around the rotating shaft in this way, the bending place can be concentrated in one place for the wire 39, and by making the wire 39 follow the movement of the rotary handle 30, it can be Prevent wire 39 from breaking.

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 clamp state of the rotary handle, and Fig. 12 shows the clamp release state of the rotary handle.

As shown in FIG. 11, the handle clamp 25 includes a clamp member 25a that clamps the rotating handle 30, and the clamp member 25a is slidably supported by the pipe portion 13 (body portion 10 ) At the mounting portion 25b, and the clamp spring 25c that pushes the clamp member 25a toward the direction (rear) where the rotary handle 30 is clamped, and the hook portion 30a provided at the rotary handle 30, and Constitute it.

The clamp member 25a is formed along the front-rear direction (telescopic direction), and a finger hooking portion 25a1 for hooking a finger is formed at the front end, and is formed as a rotation handle 30 at the rear end The locking portion 25a2 that is locked.

The mounting portion 25b is fixed by screwing to a boss 13d formed on the upper surface of the tube box portion 13 via screws 25d.

The clamp spring 25c pushes the clamp member 25a to the rear (using the rotating handle 30 in the direction of the clamp), and is composed of a compression coil spring, for example. In addition, the clamp spring 25c is disposed between the wall surface 13e erected on the upper surface of the pipe box portion 13 and the clamp member 25a.

The hook portion 30a is configured in a hole formed in the rotary handle 30. With this, it is prevented that the user's hand touches the hook portion 30a or the clothes are hooked on the hook portion 30a.

In the handle clamp 25 constructed in this way, as shown in FIG. 11, with the elastic restoring force of the clamp spring 25 c in a state where the clamp member 25 a is not operated, the clamp member 25 a The system was pushed towards the rear. With this, the locking portion 25a2 is locked to the hook portion 30a, and thereby, the rotating handle 30 is clamped (locked) in a folded state.

In addition, as shown in FIG. 12, generally, by hooking a finger at the finger hooking portion 25a1, and while receiving the pushing force of the clamp spring 25c, the clamp member 25a slides forward, and the locking portion 25a2 and the rotation The locked state between the hooking portions 30a of the handle 30 is released. With this, the clamp system of the rotary handle 30 is released, the rotary handle 30 can be turned upward, and the electric vacuum cleaner 100 can be switched from the handheld type to the upright type.

In addition, when the electric vacuum cleaner 100 is used as an upright type, the clamp member 25a is in the state shown in FIG. If From this state, turning toward the direction in which the rotary handle 30 is folded, the tapered portion 30b formed on the outer surface of the rotary handle 30 comes into contact with the tapered portion 25a3 formed on the locking portion 25a2. Thereafter, by pressing down the rotary handle 30, the pressing member 25a slides forward while receiving the urging force of the clamp spring 25c. After that, when the hook portion 30a of the rotary handle 30 passes over the locking portion 25a2, the locking portion 25a2 is locked at the hook portion 30a by the elastic restoring force of the clamp spring 25c, and the rotary handle 30 is locked The clamp is (fixed) at the body portion 10.

In this way, by fixing the rotating handle 30 to the body portion 10 with the handle clamp 25, it is possible to prevent the rotating handle 30 from shaking. In addition, since the locking can be released by sliding the jaw member 25a forward, it is possible to prevent the locking of the rotary handle 30 from being released during use.

Fig. 13 is a right side view showing the whole when the electric vacuum cleaner is used as a hand-held type.

On the right side surface of the body portion 10 (motor box portion 11), an exhaust port 10a is provided, and inside the exhaust port 10a, an exhaust filter (not shown) is provided. In addition, in FIG. 13, although the case where the exhaust port 10a is provided only on one side in the left-right direction is described as an example, it may be provided on the left and right of the body portion 10 (motor box portion 11) On both sides.

The exhaust port 10a is formed in a lattice shape in a slightly parallel direction with respect to the longitudinal direction (front-rear direction) of the motor box portion 11, and is formed at the lower portion of the surface protruding in a circle. With this, due to The openings formed by the grid are formed to face downward. Therefore, when the user holds the handle portion 30t and uses it as a hand-held type, it can exert an effect that the exhaust of the electric blower 40 is not directly blown to the user. Also, when used as a hand-held type, although the vacuum cleaner body 1 may be temporarily placed on the ground, etc., even if the liquid such as water is accidentally removed from above the body portion 10 In the case of dumping, it is also possible to prevent liquid from intruding into the inside of the main body 10, and to prevent malfunction of the electric blower 40 or the battery 60. In addition, since it is assumed that the user is a right-handed person, the exhaust port 10a is provided on the right side of the vacuum cleaner body 1 to prevent the exhaust gas from directly blowing to the user. In addition, an exhaust port may be provided on the left side to correspond to the case where the user is a left-hander, or it may be exhausted by being provided not only on one side but on the left and right sides The air volume is dispersed, and the situation that the exhaust gas directly blows to the user is suppressed.

Next, the configuration and function of the dust box 2 will be described with reference to FIGS. 14 to 33. Figure 14 is a front view of the appearance of the dust box. In addition, FIG. 14 is a state when the tube box portion 13 (refer to FIG. 2) side is observed. In the following descriptions of FIGS. 14 to 33, the front and rear directions of the illustration are referred to as up and down directions.

As shown in FIG. 14, the dust box 2 is provided with air containing dust sucked from the suction port body 3 (refer to FIG. 1) or the slit nozzle 4 (refer to FIG. 2) into dust and air. The function of collecting dust.

In addition, the dust box 2 is provided with an inflow port 149 connected to the introduction pipe 14 (refer to FIG. 1 ). What flows into this inlet 149 includes The dust air is separated into dust and air in the dust box 2 and then discharged from the upper part of the dust box 2.

Figure 15 is an exploded view of the dust box.

As shown in FIG. 15, the dust collecting box 2 is provided with an outer cylinder 128, an inner cylinder 129, a dust collecting filter 130, a filter box 131 containing the dust collecting filter 130, an upper cover 132, and a bottom cover 31, And constitute it.

The outer cylinder 128 is a cylinder formed with an opening at the top and bottom, and the opening at the lower part of the outer cylinder 128 is opened and closed by the bottom cover 133.

The inner cylinder 129 is provided with a screen box 131 at the upper portion of the inner cylinder 129, and has a structure integrated with the screen box 131. Moreover, the screen box 131 integrated with the inner cylinder 129 is inserted through the opening of the upper portion of the outer cylinder 128.

The dust collecting filter 130 is housed in the filter box 131, and by installing the upper cover 132 on the upper portion of the outer cylinder 128, it becomes a dust collecting box 2 which is integrated as shown in FIG. 14 . At this time, the inner cylinder 129 is installed so as to be slightly concentric with the outer cylinder 128.

FIG. 16 is a D-D cross-sectional view of FIG. 14.

As shown in FIG. 16, if the inner cylinder 129 is installed at the outer cylinder 128, a space for separating and collecting dust is formed between the outer cylinder 128 and the inner cylinder 129. In the space formed by the outer cylinder 128 and the inner cylinder 129, the rear part (the upper part of the figure) becomes the dust separation part 134 (refer to FIG. 16), and the front part (the lower part of the figure) becomes the dust accommodating part 135 (refer to the figure) 16). The dust separation part 134 is a space for separating dust from the air that transports the dust, and the dust storage part 135 is a space for collecting and storing dust.

The upper cover 132 is a slightly cylindrical body that opens up and down, and is formed as a filter box receiving portion 128a so as to cover a filter box receiving portion 128a provided on the upper portion of the outer tube 128 described later. The outer diameter is larger than the previous circle.

In the dust box 2, the upper cover 132 can be rotated to fix the upper cover 132 and the filter box receiving portion 128a from the state where the upper cover 132 is covered on the filter box receiving portion 128a. At the filter box receiving portion 128a, a cut-out portion (not shown) is formed on the inner surface of the upper cover 132 in such a way that it can cover the upper cover 132 only at a specific position, and is received by the filter box A protrusion (not shown) is formed at the portion 128a. If the upper cover 132 is pushed toward the outer tube 128 side and the upper cover 132 is rotated in a state where the cutout portion and the protrusion portion are aligned with each other, the protrusion portion enters the space of the cutout portion, and the upper cover 132 can be moved Fixed at 128 places on the outer cylinder. In addition, the upper cover 132 is provided with a lock button 119 and is fixed to the cleaner body 1.

The dust trap filter 130 is composed of a frame body and a filter member 147 folded into a skirt shape in the frame body. The wave direction of the filter member 147 is preferably the longitudinal direction (direction of gravity action) (refer to FIG. 15). This is because it is easy for the fine dust adhering to the filter member 147 to fall. In addition, by folding the screen member 147 into a skirt shape, the area of the screen can be increased, and the pressure caused by the screen member 147 can be reduced Force loss.

The filter member 147 is, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The so-called HEPA filter refers to an air filter equipped with a particle trapping rate of 99.97% or more for particles with a particle diameter of 0.3 μm under the rated air volume and an initial pressure loss of 245 Pa or less.

In addition, the dust filter 130 is ideally capable of being washed by a user. In addition, another filter such as a sponge filter (not shown) may be provided in front of the dust filter 130. The sponge filter is ideal to extend the frame of the dust catching filter 130 toward the front side and to be embedded in the frame. In addition, the sponge filter is ideal to allow the user to wash with water. With this, the dust trap 130 is not easily contaminated by dust, and the maintainability is improved.

In addition, the dust collection filter 130 is housed in the filter box 131 provided at the upper portion of the inner tube 129. Therefore, the dust filter 130 is located between the upper cover 132 and the filter box 131. In order for all the air passing 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 cover 132 and the filter box 131. Therefore, the dust trap filter 130 is attached to the outer periphery and is provided with a gasket 148 that is effective for maintaining airtightness between the upper cover 132 and the filter box 131.

The washer 148 is formed on the upper and lower surfaces of the flange portion 130a provided on the outer periphery of the dust filter 130, and is formed by a rubber member or the like. If the dust filter 130 is installed in the filter box 131, the gasket 148 The lower surface side is in contact with the flange portion 131a on the upper portion of the screen box 131. At the upper portion of the upper cover 132, an airtight surface 132a is provided. As described above, if the upper cover 132 is covered from above the dust filter 130, the upper side of the gasket 148 is connected to the airtight surface 132a. By fixing the upper cover 132, the dust filter 130 is pressed between the upper cover 132 and the filter box 131. At this time, as described above, it is pressure-bonded in such a manner that it can be kept airtight between the gasket 137 provided in the lower part of the screen box 131 and the outer cylinder 128.

Furthermore, a gasket 130b useful for airtight holding is also provided on the upper surface of the dust filter 130. The gasket 130b is provided so as to protrude upward from the top surface of the upper cover 132. When the dust box 2 is attached to the cleaner body 1, the airtightness between the cleaner body 1 and the dust box 2 is maintained by the gasket 130b.

The inner cylinder 129 will be described using FIGS. 17, 18 and 19. Fig. 17 is a front view of the inner cylinder, Fig. 18 is an exploded view of the inner cylinder, and Fig. 19 is an E-E sectional view of Fig. 17.

As shown in FIG. 17, the inner cylinder 129 is provided with an upper cylinder 129a having a suction portion 129c at the upper portion, and a lower cylinder 129b having a larger diameter than the upper cylinder 129a at the lower portion. And constitute it.

The side surface (peripheral surface) of the upper cylinder 129a is provided with a suction part 129c and is formed by a lattice-shaped frame body (stent bone). In addition, although the above-mentioned dust collecting box 2 is a frame body (bracket bone) in the up-down direction, it may be configured as a frame body (bracket bone) in the up-down, left-right direction Lattice.

The air intake portion 129c is surrounded by a mesh member 136 that is entirely covered on the outer peripheral surface. The mesh member 136 is held by the frame (bracket bone) by coating or insert molding. In addition, by providing the mesh member 136 at the suction portion 129c, the upper cylinder 129a has a screen function, and suppresses the inflow of fine dust toward the inside of the inner cylinder 129. In addition, the mesh member 136 may be polyester or metal (for example, stainless steel).

In addition, the suction part 129c may be configured not to adopt a frame (stent bone), but to be provided with a plurality of small-diameter through holes (holes of about Φ2 mm that can be molded by a mold). The provision of such a through hole is different from the case where the mesh member 136 is completely covered on the frame (bracket bone). It is advantageous in terms of strength and to prevent the mesh member 136 from breaking, and it is not necessary The advantages of secondary molding.

At the upper side of the upper cylinder 129a, a screen box 131 is integrally formed. The screen box 131 is substantially cylindrical and is configured to be concentric with the upper cylinder 129a. In addition, the screen box 131 has an upper portion opened, and is provided with an opening portion 131b that communicates with the inner space of the upper cylinder 129a at a slightly central portion. In addition, although the upper cylinder 129a and the screen box 131 are integrated, it is also possible to adopt a structure that can be attached and detached.

In addition, a gasket 137 is provided below the screen box 131. This washer 137 is to hold the outer cylinder 128 and the filter when the filter box 131 is accommodated in the filter box receiving portion 128a of the outer cylinder 128 described later The cages 131 are in airtight contact.

The washer 137 provided at the screen box 131 has a structure in which a ring-shaped rubber member is mounted in a recessed portion at the bottom of the screen box 131 (removable structure). However, it can also be presumed that when washing the dust box 2, the gasket 137 may be removed, and the gasket 137 may be forgotten to be installed, so the filter box may also be used. 131 and washer 137 are integrally formed (secondary forming).

As shown in FIG. 18, the lower inner cylinder 129b of the inner cylinder 129 is formed concentrically with the upper cylinder 129a (refer to FIG. 7), and is slightly cylindrical, and the upper surface is closed. In other words, the lower cylinder 129b is shaped to have a space 138 (see FIG. 19) with the bottom surface open.

In addition, the inner cylinder 129 is provided with an umbrella portion 139 that deflects the shape of the lower cylinder 129b so as to be enclosed in the space 138 (refer to FIG. 19) of the lower cylinder 129b, and is formed here The upper surface of the space 139a in the umbrella portion 139 rises downward and is formed to protrude from the space 139a so as to be convex.

The cylindrical body 140 is configured to be concentric with the umbrella portion 139, and the bottom surface 140a is occluded and has a slightly hemispherical shape. In addition, the cylindrical body 140 has a generally tapered shape whose front end is tapered as it faces the bottom surface 140a. By configuring the barrel 140 to have a generally tapered shape that narrows the front end, since it fits into a thick tapered portion at the front end of the lower portion of the outer barrel 128 described later, it becomes a container shape that expands downward. Therefore, The garbage system becomes easy to fall when discarding garbage. In addition, the system can also expand the dust collection volume, and The diameter of the cylinder 140 is reduced.

As described above, by enclosing the umbrella portion 139 in the lower cylinder 129b and providing a sliding mechanism that slides up and down, it becomes easy to discharge dust when discarding garbage. The umbrella part 139 is accommodated in the lower cylinder 129b except when discarding garbage during suction, etc., and when discarding garbage, it becomes the dust in the dust collecting box 2 by sliding downward roll out.

The sliding mechanism includes a bottomed cylindrical spring box 141, a piston 142, a stopper 143, a screw 144, and a spring 145 in the center of the umbrella portion 139.

As shown in FIG. 19, the spring box 141 is provided with a spring seat 141a and a spring shaft 141b. The outer periphery of the spring box 141 is covered by the aforementioned cylindrical body 140.

The piston portion 142 is configured to be inserted into the spring case 141. The spring shaft 141b has a structure in which the stopper member 143 is fixed by the screw 144 so as to be fixed. At the spring box 141, the spring 145 is inserted from above, and the inserted piston portion 142 integrated with the lower cylinder 129b is installed. After that, the stop member 143 is attached to the spring shaft 141b by a screw 144 or the like on.

With this structure, the sliding mechanism of the umbrella portion 139 is constituted. The stop member 143 slides up to the stop member receiving portion 129d provided on the upper surface of the lower cylinder 129b. Therefore, as mentioned above, since the sliding distance is less than the height of the space 138 of the lower cylinder 129b, the height of the blocking member 143 becomes the sliding distance The difference is slightly equal.

In the dust collecting box 2 described above, the spring box 141 is formed of separate parts, and the umbrella portion 139 is detachable. The fixing of the umbrella portion 139 and the spring box 141 is performed by a lock mechanism (not shown) provided at both locations, and the umbrella portion 139 is rotated to perform attachment and detachment. In addition, on the side surface of the spring box 141, a notch portion 141c is provided, and on the notch portion 141c, a protrusion portion (not shown) provided on the piston portion 142 is fitted and becomes an umbrella portion 139 is a rotation stopper during loading and unloading. By providing such an attachment and detachment structure of the umbrella portion 139, even when dust enters the lower cylinder 129b, it becomes possible to remove the dust by removing the umbrella portion 139. In addition, when the inner cylinder 129 is cleaned, it is easy to remove moisture by being able to be decomposed, and the handling system becomes easy. In addition, although the umbrella portion 139 and the spring case 141 are separate components, the umbrella portion 139 and the spring case 141 can be integrally formed. At this time, by making the cylindrical body 140 independent of each other, it becomes possible to mold with the mold.

The outer cylinder 128 will be described with reference to FIGS. 20 to 26. Fig. 20 is a front view showing the state where the bottom cover of the outer cylinder is opened, and Fig. 21 is a side view showing the state where the bottom cover of the outer cylinder is opened. 21 is the FF cross-sectional view of FIG. 21, FIG. 23 is the GG cross-sectional view of FIG. 21, FIG. 24 is a cross-sectional view showing other forms of the dust rewind prevention surface, and FIG. 25 is the dust rewind Fig. 26 is a cross-sectional view of HH in Fig. 16, and Fig. 27 is a motion for discarding garbage. A cross-sectional view for display.

As shown in FIG. 20 and FIG. 21, the outer cylinder 128 is a slightly cylindrical body with openings at the top and bottom, and is provided with a method of enveloping the filter box 131 (refer to FIG. 15) at the top. The filter box receiving portion 128a is formed to be one circle larger than the outer diameter of the filter box 131.

At the screen box receiving portion 128a, a flange portion 128b protruding on the outer surface side and the inner surface side is formed. The outer surface side of the flange portion 128b is in contact with the bottom surface of the upper cover 132 (refer to FIG. 15), and the outer diameter of the flange portion 128b is approximately equal to the outer diameter of the upper cover 132.

In addition, although the detailed description is omitted, the filter box receiving portion 128a is provided with a cut-out portion at one place, and is sized to avoid the protrusions provided on the outer periphery of the filter box 131 Make a cut. Therefore, the positioning of the inner cylinder 129 inserted into the outer cylinder 128 is performed by matching the position of the cutout portion and the protrusion of the screen box 131.

In addition, the height of the screen box receiving portion 128a is set to be higher than the sliding distance of the inner cylinder 129 as described above. This is because when the inner cylinder 129 is installed with the bottom cover 133 described later closed (in a state where the umbrella portion 139 (refer to FIG. 17) is protruded), the filter box 131 is accommodated in If the height of the filter box receiving portion 128a exceeds this height, the inner tube 129 becomes unstable and becomes difficult to install.

The inner diameter of the flange portion 128b is smaller than the outer diameter of the washer 137 (refer to FIG. 15) provided below the filter box 131 (refer to FIG. 15). When the filter box 131 (refer to FIG. 15) ) When fixed, the washer 137 The system is press-contacted to the upper part of the flange portion 128b and is kept airtight.

A bottom cover 133 is provided at the opening on the opposite side (the lower part of the outer cylinder 128) of the screen box receiving portion 128a. The details of the shape of the bottom cover 133 will be described later.

At the side of the outer cylinder 128, an inflow port 149 and a lid lock mechanism 150 are provided. As shown in FIG. 23, the inflow port 149 is provided on a surface (B) parallel to the horizontal axis (A). The outer wall surface 149a of the inflow port is located on the outer wall surface 128c of the outer cylinder 128. Further outside, it is configured to be connected to the outer cylinder 128 with a tangent line S2. In addition, the opening of the inflow port 149 has a slightly rectangular shape. Therefore, the outer wall surface 149a of the inlet is not parallel to the center line (C) of the longitudinal axis. In other words, the inflow port 149 protrudes more outward than the outer diameter of the outer cylinder 128. This is so that the inner cylinder 129 provided on the concentric axis with the outer cylinder 128 does not overlap with the inlet 149 when viewed from the surface of the inlet 149.

In addition, when the inner cylinder 129 is configured to face from the front surface (the side of the opening side) of the inlet 149, the air containing dust that flows in will collide with the inner cylinder 129 to separate the dust. Department will be reduced. In addition, since the side surface of the inner cylinder 129 has a mesh structure in which the mesh member 136 (refer to FIG. 15) is draped as described above, problems such as the adhesion of dust to the mesh member 136 may occur. There may also be a risk of reducing attractiveness.

Therefore, if the inflow port 149 is arranged as described above, it is also effective for reducing pressure loss and noise. another In addition, if the inlet 149 having the same opening area as the dust box 2 is accommodated in the outer diameter of the outer cylinder 128, the inner cylinder 129 faces from the inlet 149, so the aforementioned problem occurs. Therefore, it is necessary to reduce the width direction of the inflow port 149, which will increase the flow rate and cause an increase in pressure loss and noise. In order not to increase the pressure loss and noise, although it is also possible to change the aspect ratio of the inlet 149 and set it as a vertically long inlet to ensure the opening area, if it is set to be vertically long (upper and lower direction in FIG. 20) At the inlet 149, the height of the dust box 2 will increase, and the dust box 2 will become larger. The electric vacuum cleaner 100 is an upright, hand-held dual-purpose vacuum cleaner, and it is desired that the compact vacuum cleaner body 1 is also compact for the dust box 2. Therefore, by using the aforementioned dust box 2, it is possible to provide the electric vacuum cleaner 100 which compacts the vacuum cleaner body 1.

In addition, the inlet 149 is provided on a surface (B surface) that is parallel to the center line (A) of the horizontal axis shown in FIG. 23, and the surface of the inlet 149 is located at the outer cylinder 128. The outer diameter and the inner side (horizontal axis center line (A) side). At the outer cylinder 128, the introduction tube 14 (refer to FIG. 1) described later is fluidly connected. Therefore, by generally setting the surface of the inlet 149 as described above to the inner side of the outer diameter of the outer cylinder 128 It is possible to reduce the height (the height in the vertical direction), and it is possible to provide the electric vacuum cleaner 100 which makes the vacuum cleaner body 1 compact.

In addition, although the inlet 149 is illustrated in the series of FIG. 20 as an example where it is provided on the left side, it may be provided on the right side. Even if you set the inlet 149 to the right In this case, only the direction of rotation of the inflowing air will be reversed, and there will be no effect on the performance of dust separation.

The upper part of the outer cylinder 128 has a cylindrical shape. At the outer cylinder 128, it is generally surrounded by a broken line 190 in FIG. 22, and a dust rewind prevention surface 151 is provided at a slightly central portion with respect to the central axis of the outer cylinder 128 and slightly horizontally outward at a slightly vertical direction . In addition, the outer cylinder 128 is provided with a tapered shape that expands downward from the dust rewind prevention surface 151. In addition, the dust rewind prevention surface 151 is enlarged from the cylindrical inner peripheral surface of the upper part of the outer cylinder 128 by about 2.5 mm.

As shown in FIG. 26, in a state where the inner cylinder 129 is installed in the outer cylinder 128, the lower surface of the umbrella portion 139 of the inner cylinder 129 is located in the cylinder above the outer cylinder 128, and the dust is accumulated in the inner cylinder Below the umbrella portion 139 of the barrel 129 (lower than the flange portion 146 (refer to FIG. 17)). Therefore, the dust rewind prevention surface 151 is used to prevent the dust accumulated in the lower part of the tapered portion of the outer cylinder 128 or the dust contained in the air returned from the dust accommodating portion 135 (FIG. 16) The inner surface of the outer cylinder 128 is rolled back. By this, since it is possible to suppress the attachment of dust to the mesh member 136 (refer to FIG. 15) on the side of the inner tube 128 and the blowing of fine dust through the mesh member 136, it is possible to provide a There is an electric vacuum cleaner 100 of the dust box 2 that suppresses the decrease in attractive force.

In addition, by providing the dust rewind prevention surface 151 and making the lower portion tapered from the dust rewind prevention surface 151, the volume of the outer cylinder 128 is expanded, and more dust can be accumulated. In addition, it was tilted about 8 degrees from the state where the central axis of the dust box 2 was set in the vertical direction oblique.

In addition, the portion surrounded by the dotted line 190 in FIG. 22 may also be provided with a circular ring-shaped rib 152 in a slightly vertical direction below the dust rewind prevention surface 151 as shown in FIG. 24. The annular rib 152 extends from the upper cylindrical portion and protrudes from the inner side of the tapered portion, and can further prevent the dust from rewinding along the inner wall of the outer cylinder 128.

In addition, the portion surrounded by the dotted line 190 in FIG. 22 can also be provided as shown in FIG. 25, and is provided with a cylindrical shape at the upper portion and is slightly centered compared to the dust box 2 The dust rewind prevention surface 151A, which is inclined further upward in the vertical direction of the central axis, is assumed to be gradually expanded from the dust rewind prevention surface 151A downward in a tapered shape. By providing such inclined dust rewind prevention surface 151A, it is possible to suppress the attachment of dust to the mesh member 136 on the side of the inner cylinder 129 and the blowing of fine dust through the mesh member 136 Therefore, it is possible to provide an electric vacuum cleaner 100 equipped with the dust box 2 that suppresses the reduction of attractive force.

As shown in FIG. 26, the bottom cover 133 is in the shape of a dish with a depth, and is provided with a gasket 157 on the outer periphery of the upper surface, and becomes able to maintain the bottom cover 133 when the bottom cover 133 is closed. The bottom of the barrel 128 is airtight. In addition, the bottom cover 133 is formed into a dish shape to increase the strength. In addition, a part of the outer periphery of the bottom cover 133 is provided with a hook portion 155 (see FIG. 21) for locking the bottom cover 133 to the outer tube 128. At the outer cylinder 128, it is opposite to the hooking part 155 At this point, a pivot portion 158 (refer to FIG. 21) provided with a rotating shaft 158a (refer to FIG. 21) is provided.

As described above, when the dust box 2 is mounted on the cleaner body 1, the concave portion 159 (refer to FIG. 33) on the bottom surface of the bottom cover 133 is fitted into the dust box fixing protrusion 13a of the cleaner body 1 (refer to 33), the dust box 2 is pressed and attached to the cleaner body 1 side using the dust box fixing protrusion 13a as a starting point. After that, by using the lock button 119 (refer to FIG. 16) on the upper part of the upper cover 132 to lock, the dust box 2 is integrated with the cleaner body 1. Therefore, if the dust box 2 is mounted on 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), there is a possibility that the lid lock mechanism 150 may be released during cleaning. However, by locking the lid lock mechanism 150 Hidden on the side of the vacuum cleaner body 1, it can prevent malfunction. For example, when cleaning under the sofa or under the bed in an upright state, the cleaner body 1 may be approached horizontally with respect to the ground. However, at this time, the lid lock mechanism 150 When it is installed on the surface side, there is a possibility that the cover lock mechanism 150 may be released due to mutual contact with the ground. The positions of the cover lock mechanism 150 and the pivot portion 158 are not limited to this, and may be provided on the left and right relative to the cleaner body 1. By being disposed on the left and right, the aforementioned malfunction can be prevented, and the protrusion of the pivot portion 158 can also disappear. Therefore, the height in the front-rear direction can be shortened and the body can be made compact.

In addition, the bottom cover 133 is provided with a dish-shaped center protruding In addition, a concave portion 170 having a concave shape is formed in the central portion from the protruding portion. The recessed portion 170 is configured to be larger than the spherical radius of the spherical surface of the bottom surface 140a of the cylindrical body 140. The recessed portion 170 is configured such that the bottom cover 133 is in an open state (relative to the bottom surface of the outer cylinder 128) In the vertical state), no horizontal plane appears at the recess 170. In addition, the recess 170 is made as shallow as possible, so that no dust remains in the recess 170 when the garbage is discharged.

In addition, the concave portion 170 is formed as an independent body, and in order to reduce the wear of the components caused by the friction between the bottom cover 133 and the cylinder 140 when the bottom cover 133 is opened and closed, POM (polyoxymethylene) or the like is used. Material to form. In addition, the recess 170 can also be integrally formed.

The lid lock mechanism 150 is composed of a lid lock cover 153, a key 154, and a spring (not shown).

The cover lock cover 153 is provided with a rotating shaft and a spring seat (both not shown), and is provided with a cut-out portion at a part of the side surface and a part of the bottom surface.

The key 154 is provided with a gripping portion, a claw portion, a shaft hole, and a spring shaft (none of which are shown). At the rotation axis of the cover lock cover 153, a shaft hole of the key 154 is fitted. If one end of a spring (not shown) is inserted into the spring shaft of the key 154, and the other end is fixed to the spring seat of the cover lock cover 153, the pinching part of the key 154 is locked from the cover lock cover 153 The side cutout protrudes, and the claw part protrudes from the bottom cutout. The outer cylinder 128 is provided with a protrusion and a screw boss (not shown) opposite to the position of the cover lock cover 153, and the cover lock cover 153 is screwed to the outside At the barrel 128, a lid lock mechanism 150 is formed.

Using the side of the cover lock cover 153 (opposite to the pinch grip) as a fulcrum, the spring (not shown) is shortened by pinching the pinch grip, and the claw is rotated within the movable range. When the grip force is relaxed, the spring (not shown) returns to its natural length, and the pinch grip part is returned to the state where it protrudes from the cover lock cover 153. When the lid lock mechanism 150 is operated with the bottom cover 133 closed, the claw of the button 154 is disengaged from the hook portion 156 provided at the bottom cover 133, and the bottom cover 133 is opened. The claw part and the hooking part 156 are provided with inclined surfaces each other. By closing the bottom cover 133, the inclined surfaces are in contact with each other. By pushing the bottom cover 133 up further, the button 154 obtains a rotational force and a spring ( (Not shown) is shortened, the claw part goes over the hooking part 156 and the bottom cover 133 is closed again.

In the structure of the dust box 2 provided with the outer cylinder 128 and the inner cylinder 129 as described above, by mounting the inner cylinder 129 in the outer cylinder 128, the sliding mechanism provided at the inner cylinder 129 is The bottom cover 133 provided at the lower end of the outer tube 128 is opened and closed. As shown in FIG. 27, in the state where the bottom cover 133 is opened, the umbrella portion 139 is tied downward and protrudes. If the bottom cover 133 is closed, the spring 145 is shortened and the umbrella portion 139 is housed in Inside the lower cylinder 129b. Therefore, when the lid lock mechanism 150 of the bottom cover 133 is released when the garbage is discarded, the umbrella portion 139 is ejected downward and the dust is pushed out.

In such a sliding mechanism, the spring 145 is in a state close to the natural length, and the body is the state where the umbrella portion 139 is most popped up. The sliding distance of the upper and lower parts of the umbrella part 139 is the same as the above, and it is set to be less than the lower part The height of the space 138 of the cylinder 129b. In other words, the upper surface 139c of the umbrella portion 139 (refer to FIG. 18) is configured not to exceed the bottom surface 129e of the lower cylinder 129b (refer to FIG. 18). This is to prevent dust from being caught between the bottom surface 129e and the upper surface 139c by discarding as little space as possible between the bottom surface 129e of the lower cylinder 129b and the upper surface 139c of the umbrella portion 139 when discarding garbage For the sake of suppression. In addition, the umbrella portion 139 is provided with the minimum clearance necessary to allow easy sliding in the space 138 in the lower cylinder 129b. In addition, since the umbrella portion 139 is located in the dust accommodating portion 135, if the gap (gap) between the outer periphery of the umbrella portion 139 and the lower cylinder 129b is too small, it can be presumed that dust may be bitten into the gap and It becomes difficult to slide. The dust collecting box 2 is provided with a clearance considering the bite of the dust, and by providing a plurality of ribs 139b (refer to FIG. 18) on the outer periphery of the umbrella portion 139, the gap will be increased The sway of sliding caused by the big event is reduced. Furthermore, the umbrella portion 139 is provided with a stepped portion 139d (refer to FIG. 18), and the stepped portion 139d and the bottom surface 129e (refer to FIG. 18) of the lower cylinder 129b are opposed to each other (the umbrella portion 139 is accommodated in the lower circle In the state of the space 138 of the cylinder 129b, the gap between the lower cylinder 129b and the umbrella portion 139 disappears. With this, it is possible to suppress the dust entering the gap between the lower cylinder 129b and the umbrella portion 139 when the dust is attracted. Further, at the bottom of the umbrella portion 139, a flange portion 146 (refer to FIG. 18) is provided, and by this flange portion 146, the dust is returned from the dust accommodating portion 135 (refer to FIG. 16) to the dust separating portion 134 (Refer to FIG. 16) The situation at this point is suppressed. In addition, since the dust is accumulated under the flange part 146, as long as the dust will exceed the flange part The timing before 146 may be set as the timing of dust emission.

Next, the operation when discarding garbage will be described with reference to FIGS. 26 and 27.

As shown in FIG. 26, the bottom cover 133 is released by pinching the button 154 (refer to FIG. 20) of the cover lock mechanism 150 provided at the side of the dust box 2. That is, the bottom cover 133 is on the opposite side of the cover lock mechanism 150, and is provided with a pivot portion 158 (refer to FIG. 21), and rotates with the rotation axis 158a (refer to FIG. 21) of the pivot portion 158 as an axis As shown in FIG. 27, the bottom cover 133 is slightly vertical (the upper surface of the bottom cover 133 is vertical).

Simultaneously with the opening of the bottom cover 133, by the urging force of the spring 145, the umbrella portion 139 and the cylinder 140 are ejected downward from the opening at the lower end of the outer cylinder 128. As a result, the position of the umbrella portion 139 is closer to the opening of the lower surface of the outer cylinder 128 compared to the position when the bottom cover 133 is closed. By the sliding action of the umbrella portion 139, the collected dust is pushed downward.

After the trash is discarded, when the bottom cover 133 is closed, the bottom surface 140a of the barrel 140 that is ejected downward is in contact with the concave portion 170 provided at the center of the bottom cover 133, and the umbrella portion 139 and the barrel 140 are Push upwards. Since the bottom surface 140a of the barrel 140 and the recessed portion 170 are connected in a spherical shape, even if the angle of the bottom cover 133 changes due to the action of closing the bottom cover 133, the bottom surface 140a of the barrel 140 can be changed The contact area with the recess 170 is kept constant, In addition, by bringing these curved surfaces into contact with each other, since the force is constantly applied in the vertical direction, the umbrella portion 139 is smoothly accommodated in the lower cylinder 129b. In addition, when the recess 170 is not provided at the bottom cover 133 and the surfaces are in contact with each other, since the direction of the applied force is perpendicular to the plane, it is difficult for the umbrella portion 139 to return vertically, and the bottom cover 133 The system becomes difficult to close. Also, if the bottom cover 133 is closed to a slightly horizontal state, the hooking portion 156 and the hooking portion 155 (refer to FIG. 21) are engaged with each other, and are airtight by the gasket 157 provided at the bottom cover 133 Locked in a state of keeping.

Next, for the shape and structure of the introduction pipe 14 that guides the air containing dust into the dust box 2 at the upstream side of the dust collector 2 at the electric vacuum cleaner 100, refer to FIG. 28 ~ Figure 33 to illustrate. Fig. 28 is a perspective view showing the positional relationship between the dust box and the introduction pipe, Fig. 29 is a view showing the flow of air in the pipe box, and Fig. 30 is a section II of Fig. 29 Fig. 31 is a front view showing the positional relationship between the dust box and the introduction pipe, Fig. 32 is a view showing the flow of air inside the dust box, and Fig. 33 is A sectional view showing the airtight structure of the dust box and the vacuum cleaner body. In addition, the element symbol 171 shown in the figure represents dust, and the arrow A represents the flow of air.

As shown in FIG. 28, the upright/handheld dual-purpose electric vacuum cleaner 100 is equipped with a flow inlet from the suction port 15 at the front end of the vacuum cleaner body 1 to the dust box 2 (outer cylinder 128) The introduction pipe 14 of the flow path up to 149. In Figure 28, it is the In the state where the dust box 2 is mounted on the cleaner body 1, parts are omitted, and only the introduction pipe 14 and the dust box 2 are exhibited.

The introduction pipe 14 is provided with an introduction pipe outlet 161 which is opened at the front and rear and connected to the suction port 15 at the front and connected to the inlet 149 of the dust box 2 (outer cylinder 128) at the rear. In addition, the introduction pipe 14 is provided with linear pipes 160a and 160b. The linear pipe 160a is located on the side of the dust box 2, and the linear pipe 160b is located in front of the bottom cover 133.

As shown in FIG. 29, the central axis (D) of the dust box 2 is positioned on the same line (parallel) as the central axis (not shown) of the cleaner body 1 when viewed from above. As described above, the dust box 2 is positioned below the straight portion (straight pipe 160a).

The central axis (E) of the straight portion (straight piping 160a) of the introduction pipe 14 is parallel to the central axis (D) of the dust box 2. The introduction tube 14 is slightly S-shaped, and the suction port body 3 (refer to FIG. 1) is connected to the suction port 15 at the front end (front). In addition, the introduction pipe 14 is provided with a straight pipe 160a formed from the inflow port 149 (refer to FIG. 20) of the outer cylinder 128 to the bottom of the outer cylinder 128, and along the outer surface of the bottom cover 133 The inclined piping 160c bent to the direction toward the center of the bottom cover 133 and the straight piping 160b extending toward the front.

The central axis (F) of the linear piping 160b is positioned on the same line as the central axis (D) of the dust box 2 when viewed from above. In other words, the introduction pipe 14 is such that the central axis of the linear pipe 160a and the central axis (F) of the linear pipe 160b having the suction port 15 are parallel to each other, and The two straight pipes 160a and 160b are connected diagonally downward to form a connected pipe. The angle of inclination of the pipe 160c connecting the two straight pipes 160a and 160b toward the oblique downward direction differs depending on the position of the suction port 15, however, it is configured such that the position (range) of the suction port 15 is located The general shape in the bottom surface of the dust box 2 (inside the outer diameter of the bottom cover 133).

In addition, the introduction tube 14 is housed in the tube box portion 13 of the cleaner body 1, and the tube box portion 13 has a shape in which the left side is expanded when viewed from above. At the outlet 161 of the introduction pipe connected to the inlet 149 of the dust box 2, a gasket 162 is provided. If the dust box 2 is mounted on the cleaner body 1, the gasket 162 and the inlet 149 are pressed against each other Connect and become airtight.

The gasket 162 is formed by using a member made of rubber or a sponge-like member that does not have air permeability, etc., to be generally integrated with the outlet 161 of the inlet pipe (secondary molding), or is sandwiched by the inlet pipe The outlet 161 and the tube box portion 13 are fixed so as to maintain the airtightness between the inlet 161 and the gasket 162. Furthermore, although the gasket 162 may not be provided at the outlet 161 of the introduction pipe but at the inlet 149 of the dust box 2, when the dust box 2 is made washable, when the gasket 162 In the case of a separate part, there is a possibility that the gasket 162 may be forgotten to be installed. Therefore, it is desirable to install it at the outlet 161 of the introduction pipe as described above.

The air sucked from the suction port 15 follows the shape of the introduction pipe 14 and flows generally as indicated by the arrow A. At this time, the density is relatively empty The dust 171 with greater air and weight is pushed to the right inner wall surface side (left inner wall surface side in the figure) of the linear piping 160a by the inertial force by tilting the pipe 160c, and along the right inner wall surface side ( (The left inner wall surface side in the illustration) is transported toward the dust box 2. The right inner wall surface side of the straight pipe 160a is connected to the right inner wall surface of the inflow port 149 provided at the outer cylinder 128, so it is connected to the inner wall surface of the outer cylinder 128 in a tangential direction. Therefore, the dust 171 transported along the right inner wall surface of the straight pipe 160a is swirled on the inner wall surface of the outer cylinder 128 which is farthest from the outer circumference of the inner cylinder 129, so the centrifugal separation performance is improved.

As shown in FIG. 31, according to the drawing from the suction port 15 side (front), the straight pipe 160a is positioned above the straight pipe 160b provided with the suction port 15. Therefore, The above-mentioned flow is the same. Since the dust 171 is transported toward the upper side of the inner wall surface of the linear pipe 160a by the inertial force 180, the dust 171 is transported above the outer cylinder 128. By this, it can be used effectively for the height direction of the inflow port 149, and can be used effectively for the length of the dust separation part 134 (refer FIG. 16).

The higher the dust separation portion 134 (the longer in the front-rear direction), the higher the centrifugal separation performance of the dust. Therefore, by making the introduction pipe 14 curved as described above, it is possible to provide a device which has the height of the dust separation part 134 suppressed (compacted) and also has the centrifugal separation performance. The electric vacuum cleaner 100 of the dust box 2 secured.

In addition, the provision of the bent portion at the introduction pipe 14 is also correct It helps to make the vacuum cleaner body 1 compact. For example, when sweeping under a sofa or under a bed in an upright form, it is a general action to bring the cleaner body 1 close to the floor and let the suction nozzle body 3 enter a narrow gap. At this time, if the introduction pipe system has a shape extending straight, the vacuum cleaner body 1 cannot be brought close to the ground unless the introduction pipe is made long. Therefore, by bending the introduction tube 14 as described above, the front and rear lengths of the vacuum cleaner body 1 can be shortened, and a compact electric vacuum cleaner 100 can be provided. In addition, as a method of shortening the length of the front and back of the vacuum cleaner body 1, although the diameter of the dust collecting box 2 can also be reduced, it is possible to approach the ground without making the introduction tube too long, but If the diameter of the dust box 2 is reduced, there is a risk that the separation performance and the amount of dust collected will be reduced and the pressure loss will be further deteriorated. Therefore, by bending the introduction pipe 14 as described above, the dust collecting box 2 can have a high separation performance, a large dust collection amount, and a small pressure loss, and can provide a compact electric vacuum cleaner 100 .

In addition, even if the introduction tube 14 has a straight shape, the dust collecting box 2 is provided above the cleaner body 1 (above the tube box portion 13) by being different from the electric vacuum cleaner 100 described above. The aforementioned general action of bringing the cleaner body 1 close to the ground and causing the suction port body 3 to enter a narrow gap. However, since the inflow port 149 of the dust box 2 faces upward, when the cleaner body 1 is swept close to the ground, or in a hand-held state, the posture of the cleaner body 1 becomes that of the dust box 2 When the upper part (dust filter 130 side) is swept downwards, there will be dust left in the inlet pipe when the operation is stopped 14 within the risk. In order to solve this problem, although there is a product provided with a check valve at the inflow port 149, however, as a result, there may be an increase in pressure loss caused by the check valve or dust may be caught in the check valve In the middle of it. Therefore, by arranging the dust box 2 below the cleaner body 1 and bending the introduction tube 14 as described above, the dust becomes difficult to remain in the inflow port 149 regardless of the various cleaning positions Therefore, it is possible to suppress an increase in pressure loss caused by the installation of a check valve, etc., or to prevent dust from getting stuck in the check valve, and to provide a compact electric vacuum cleaner 100.

Also, as described above, if the cleaner body 1 is viewed from above, the left side of the tube box portion 4 is expanded. In other words, although the central axis of the dust box 2 and the central axis of the cleaner body 1 are parallel (on the same line), the axis of the linear pipe 160a of the introduction pipe 14 is not positioned on the same line of the two axes. In this way, by adopting an asymmetrical arrangement in which the introduction tube 14 deviates from the cleaner body 1 (dust box 2) in the left-right direction, in the upright type, the cleaner body 1 can be made difficult Collision with the user's body. When the introduction tube 14 is arranged on the right side (the left side in the figure) when viewed from the front as described above, the left side of the vacuum cleaner body 1 is less swollen, so right-handed users The system is easy to use, and when the introduction tube 14 is arranged on the left side, the left-handed user system becomes easy to use. The switching between the right side and the left side only needs to be exchanged for the outer tube 128 and the introduction tube 14 and the tube box portion 13, so it is possible to provide a circuit that can realize a universal design with a small number of parts exchanged Motion cleaner 100.

As shown in FIG. 32, if the user starts operation through the operation button 31a or the operation button 31b provided at the rotary handle 30 (refer to FIGS. 1 and 2), the battery 60 is used for the electric blower. 40 power supply. After that, the electric blower 40 is driven to suck in air. The sucked air flows from the suction port 15 of the introduction pipe 14 through the introduction pipe outlet 161 to the dust collecting box 2 through the inflow pipe 149 (flow 200). At this time, the dust is pushed to the right inner wall surface of the introduction tube 14 by the curved portion of the introduction tube 14 (refer to FIG. 29 ), while being inside the dust box 2 from the tangent S2 direction of the outer tube 128 ( Refer to Figure 23). The inflowing air containing dust becomes a swirling flow, and centrifugal force acts on the dust, and the dust and air are separated (flow 201). That is, at the dust separation part 134 which is the upper part in the dust storage part 135, the dust and the air system are separated. Most of the separated air flows into the inner cylinder 129 from the suction part 129c provided at the upper inner cylinder 129a (flow 202). After that, the air system passes through the dust trap filter 130, and then passes through the upper opening of the upper cover 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 suction part 129c is collected by the dust collection 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 transported into the dust storage portion 135. At this time, since the centrifugal force acts on the dust, the dust rotates in the dust storage portion 135 (flow 204). However, if the electric vacuum cleaner 100 continues When used, the dust gradually accumulates, and when the dust accommodating portion 135 becomes full (doughnut-shaped), it is a time to discard garbage.

In addition, the air flowing into the dust accommodating portion 135 may have a shape along the cylindrical body 140 and the space 139a of the umbrella portion 139, and may flow from the vicinity of the outer periphery of the lower cylinder 129b toward the upper inner cylinder 129a side ( Flow 205). In order to suppress the dust caused by this air flow back to the upper inner cylinder 129a side, the umbrella portion 139 needs to have a depth. Since the dust collecting box 2 is provided with a sliding mechanism for pushing the dust to the lower cylinder 129b, the umbrella portion 139 is provided with a sufficient depth. Further, by the dust rewind prevention surface 151 (refer to FIG. 22) provided at the upper end of the tapered portion of the outer cylinder 28, the return of the dust toward the upper cylinder 129a side is further suppressed.

When the dust storage unit 135 is full of dust, the garbage is discarded. However, the garbage discharge mechanism is as described above. Even when the amount of dust attracted is small, the umbrella can be used. The sliding mechanism of the part 139 and the tapered shape of the outer cylinder 128 discharge the dust.

In addition, it is effective to provide a mechanism for discharging dust from below the dust box 2 in this way, which is effective for an electric vacuum cleaner (rechargeable electric vacuum cleaner) having a body terminal 12d behind the dust box 2 Therefore, it is possible to suppress the dust from adhering to the rear side of the dust box 2 (the upper cover 132 side).

Next, the structure of the dust box attachment/detachment mechanism (lock key) will be described.

As shown in FIG. 33, at the tube box portion 13, a dust box fixing protrusion 13a useful for fixing the dust box 2 is provided, and at the motor box portion 11, a dust box 2 is provided for effectively fixing the dust box 2 For fixing the fixing hole 118 of the dust box. The dust collecting box 2 is provided with a lock button 119 which is pushed by the lock button spring 120. By inserting the dust box fixing protrusion 13a into the concave portion 159 on the bottom surface of the dust box 2, and using the dust box fixing protrusion 13a as a starting point to rotate it to the side of the pipe box portion 13, the lock button 119 is hooked Hanging in the dust box fixing hole 118, the dust box 2 is integrated with the cleaner body 1.

When the dust box 2 is detached, by sliding the lock button 119 toward the front side, the lock button 119 is disengaged from the dust box fixing hole 118, and by directing the dust box 2 in the opposite direction to the installation By turning, the recessed part 159 can be detached from the dust box fixing protrusion 13a.

As shown in FIG. 33, at the bottom surface (back surface) of the bottom cover 133, a recessed portion 159 is provided at the tube box portion 13 side of the vacuum cleaner body 1, and becomes a protrusion for fixing the dust box of the vacuum cleaner body 1. 13a and the concave portion 159 (refer to FIG. 3) on the bottom surface of the bottom cover 133 are fitted together. In addition, the dust box fixing protrusion 13a and the recessed portion 159 are formed to have a wide width in the left-right direction (the vertical direction of the paper surface in FIG. 33). With this, when the dust box 2 is mounted on the cleaner body 1, the situation in which the dust box 2 moves toward the direction of rotation is suppressed.

At the airtight surface 112 formed by partitioning the electric blower 40 and the dust box 2 arranged at the main body 10, a suction part 113 is provided to connect the electric blower 40 and the dust box 2 together. Inhale here In the air flow path of the part 113, a protective filter 115 is provided to prevent the dust from intruding into the interior of the electric blower 40 when the dust box 2 is removed and the operation is inadvertently performed. To prevent.

In addition, the protection filter 115 is preferably constructed so as to be able to be cleaned when soiled so that it can be freely attached and detached from the main body 10, and is composed of a material that can be washed with water. In addition, the protection filter 115 is fixed to the body portion 10 by the protection filter cover 114. The protective filter cover 114 is ideally a lattice-shaped hole composed of holes that cannot be entered by the fingers in a manner that does not allow the user's fingers to contact the electric blower 40.

The main body portion 10 is located on the upstream side of the electric blower 40, and is provided with a shock-proof airtight rubber 116 composed of an elastomer sealing member such as rubber. By the shock-proof airtight rubber 116 and the protection filter cover 114 The flat surfaces on the outer periphery are tightly attached to each other to ensure airtightness. Since the anti-vibration airtight rubber 116 is fixed in the fixed box 11a and is fixed together with the electric blower 40, it also has a function of absorbing the rotational vibration action caused by the driving of the electric blower 40.

In addition, when the dust box 2 is mounted on the body 10, if it is pushed in from the bottom (horizontal direction) while moving in parallel, the gasket 120b will be lifted up, and there is no guarantee of dust collection. There is a risk of air tightness between the tank 2 and the suction part 113. Therefore, the dust box is fixed by providing the concave portion 159 at the dust box 2 and the dust box fixing protrusion 13a fitted in the concave portion 159 at the tube box portion 13 (main body portion 10) The protrusion 13a rotates as a fulcrum P. Furthermore, the airtight surface 112, position It is placed further back (upper side in the figure) than the tangent line S3 of the upper end surface 2s of the dust collecting box 2 to rotate. However, when the dust box 2 is pushed in to the maximum, the upper end surface 2s of the dust box 2 and the airtight surface 112 become parallel, and the gasket 130b is made at the entire circumference of the opening edge of the suction portion 113 contact. In addition, the airtight surface 112 of the body portion 10 is inclined at a specific angle α (for example, 5 degrees) with respect to the up-down direction (horizontal direction in the figure).

In addition, the gasket 130b is shaped to expand toward the rear (upward in the figure) in the cross-sectional view shown in FIG. 33, and further toward the front (downward in the figure) at the rear end. ) Made a reversed shape. With such a shape, it is difficult for the gasket 130b to be lifted when the dust box 2 is detached. Moreover, even if the gasket 130b is not strongly pressed to the suction portion 113, the suction force caused when the electric blower 40 is driven becomes negative pressure, and the gasket 130b is attracted to the suction portion 113. The airtight system between the dust box 2 and the suction part 113 is reliably ensured.

In this way, in the aforementioned electric vacuum cleaner 100, the vacuum cleaner body 1 is provided. The vacuum cleaner body 1 is provided with: a body portion 10 having an electric blower 40; The telescopic tube 20 installed; and a rotating handle 30 rotatably mounted at the front end of the telescopic tube 20 toward the telescopic direction (front-rear direction) of the telescopic tube 20. By this, since the position of the rotary handle 30 is close to the electric blower 40 of the body portion 10, when the electric vacuum cleaner 100 is used in a hand-held state, the rotary handle 30 can be brought close to the center of gravity Ga of the electric vacuum cleaner 100 (reference Figure 2), without The user's hand creates a great burden. In addition, when the electric vacuum cleaner 100 is used in an upright state, since the center of gravity Ga of the electric vacuum cleaner 100 can be positioned close to the ground, there is no possibility of causing a large burden on the hand of the user.

Also, in the electric vacuum cleaner 100, the rotating handle 30 is provided around the opening 32 formed in an elongated shape, and is provided with handle portions 30s and 30t. The telescopic tube 20 is accommodated in the body portion 10 and the rotating handle 30 When it is turned to the telescopic tube 20 side and folded (in a hand-held state), the opening 32 is positioned above the electric blower 40. By this, since the position of the handle portion 30t and the center of gravity Ga (refer to FIG. 2) of the electric vacuum cleaner 100 can be matched with each other in the front-rear direction, when used as a handheld state, there is no The situation that the hand causes a big burden.

In addition, in the electric vacuum cleaner 100, when the telescopic tube 20 is accommodated in the main body 10 and the rotating handle 30 is folded, the length of the electric blower 40 in the longitudinal direction (front-rear direction) and the longitudinal direction of the main body substrate 50 The length of the (longitudinal direction) of the two (the length of the battery 60 in the longitudinal direction (front-to-rear direction)) is configured to be slightly equal to the length of the opening 32 of the rotary handle 30 in the longitudinal direction . By this, since the center of gravity Ga (refer to FIG. 2) of the electric vacuum cleaner 100 is positioned close to (near) the rotary handle 30, it is easy to use the electric vacuum cleaner 100 as a handheld type. It is easy to take and clean, and the convenience of use is improved. In addition, when the electric vacuum cleaner 100 is used in an upright state, the electric vacuum cleaner The center of gravity of 100 is not on the hand but on the ground, so it can be cleaned without causing a great burden on the user's hand, and the convenience of use is improved. In this way, it is possible to realize an electric vacuum cleaner 100 that is easy to use regardless of whether it is a handheld type or an upright type. In addition, when the electric vacuum cleaner 100 is stored, it can be stored in a place with a low height by making it a handheld type.

In addition, the lid lock mechanism 150 provided at the dust box 2 is installed in the hidden position when the dust box 2 is mounted on the cleaner body 1 because the lid lock mechanism 150 is arranged. Therefore, it is possible to prevent the lid lock mechanism 150 from being released during operation and accidentally discharging the dust collected in the dust box 2. In addition, although the cleaning brush 172 is detachably provided in the dust box 2, the cleaning brush 172 is also hidden when the dust box 2 is attached to the cleaner body 1 Therefore, the system does not fall off during operation, and there is no need to separately store the cleaning brush 172 in a place different from the electric vacuum cleaner 100.

In addition, since the operation direction of the lock button 119 when removing the dust box 2 from the cleaner body 1 is directed forward (downward direction in FIG. 33), it is possible to prevent the dust box 2 from being operated When it comes off from the cleaner body 1.

Next, the configuration of the charging stand 70 will be described with reference to FIGS. 34 to 40.

As shown in FIG. 38, when the body terminal portion 12 is fitted to the charging station terminal portion 73, the body terminal 12d is in contact with the charging terminal 73c, and by further lowering the edge portion 12f of the body terminal 12d, The charging terminal 73c is bent and deformed toward the rear. The charging terminal 73c is provided with a spring property that pushes forward, so that the main body terminal 12d and the charging terminal 73c maintain contact with each other while the cleaner body 1 is mounted on the charging stand 70. The battery 60 is continuously charged.

In addition, since the charging station terminal portion 73 is concave-convexly fitted with the main body terminal portion 12, even if the user touches the cleaner body 1 during charging, for example, the main body terminal 12d and the charging terminal 73c will not be caused. When the conduction state (contact state) between them is released.

At the charging stand 70 configured in this manner, since the charging stand terminal 73 is formed at the upper surface 72a of the upright part 72, when the charging stand terminal 73 and the body terminal 12 are aligned with each other, it is It becomes a position close to the line of sight of the user, and it becomes easy to insert the body terminal portion 12 into the charging stand terminal portion 73, and it becomes easy to mount the cleaner body 1 on the charging stand 70.

In addition, at the charging stand 70, the charging stand terminal portion 73 is formed at the upper surface 72a of the standing portion 72. That is, since the charging station terminal portion 73 is formed at a position higher than the ground, the system becomes less likely to accumulate dust on the charging station terminal portion 73, and it can also reduce the dust from being rolled up from the ground And attached to the situation.

In addition, at the electric vacuum cleaner 100 mounted on the charging stand 70, the charging station terminal 73 is positioned close to the center of gravity Ga (refer to FIG. 2) of the electric vacuum cleaner 100 (position of the electric blower 40 and the battery 60) Therefore, by carrying the vicinity of the center of gravity Ga with the charging table terminal portion 73, it is possible to stably hold the cleaner body 1 on the charging table 70 during charging.

In addition, when charging is performed in the state where the suction port body 3 is connected to the electric vacuum cleaner 100 at the charging stand 70, since it can be supported by the mounting surface 71a of the base portion 71, it can be The charging station terminal portion 73 and the suction port body 2 support the electric vacuum cleaner 100 in two places, and the electric vacuum cleaner 100 can be stably held on the charging station 70.

Moreover, by applying the electric vacuum cleaner 100 to the charging stand 70, the system can be charged with the dust box 2 removed, so even if the dust box 2 is being washed and dried In the middle, it can also be charged.

As shown in FIG. 39, the electric vacuum cleaner 100 can be charged in a hand-held state, and as shown in FIG. 40, the electric vacuum cleaner 100 can also be charged in an upright state. In this way, the electric vacuum cleaner 100 can be mounted on the charging stand 70 in either the hand-held state or the upright state. At this time, by attaching the suction nozzle body 3 and installing the electric vacuum cleaner 100, since the lower surface of the suction nozzle body 3 is supported by the mounting surface 71a of the base portion 71, the electric vacuum cleaner 100 can be supported more stably.

Moreover, since the charging table terminal portion 73 is formed at a position higher than the ground surface of the upper surface 72a of the upright portion 72, as shown in FIG. 39, when the application nozzle body 5 is held on the charging table 70 When the electric vacuum cleaner 100 is installed on the charging stand 70 in a state where it is in contact, the contact between the electric vacuum cleaner 100 and the application nozzle body 5 can be suppressed, that is, the electric vacuum cleaner 100 first comes into contact with the upright portion 72, and It is possible to suppress the situation where the application nozzle body 5 falls off from the application nozzle body fixing protrusion 71c.

In addition, the charging stand 70 can function as a stand when accommodating the cleaner body 1 even when the power cord 76 is not connected and the battery 60 is not charged.

The vacuum cleaner body 1 is detachably provided with a suction port body 3 and a charging stand 70. In addition, although the electric vacuum cleaner 100 is a rechargeable vacuum cleaner that charges the battery 60 by the charging stand 70 and is used as a power source, it can also be equipped with a power cord at the vacuum cleaner body 1 and used as an AC type To use the electric vacuum cleaner.

Next, the self-supporting structure of the electric vacuum cleaner 100 will be described with reference to FIGS. 41 and 42. Fig. 41 is a cross-sectional view showing the suction port body, and Fig. 42 is a side view of the electric vacuum cleaner when it is held in a hand-held state.

As shown in FIG. 41, the mouthpiece body 3 is composed of a mouthpiece box 3a and a mouthpiece connector 3b.

The suction box 3a is attached to the lower surface (the surface facing the cleaning surface), and is formed with a suction chamber Q having an opening. Also, in this suction chamber At Q, the first rotating cleaning body 3c and the second cleaning rotating body 3d are provided.

The first rotating cleaning body 3c is rotated by the driving force of a motor (not shown), and is rotatably supported by the suction box 3a. The second rotating cleaning body 3d is provided with a brush having a smaller diameter than the diameter of the first rotating cleaning body 3c, and is arranged behind the first rotating cleaning body 3c. In addition, the suction box 3a is provided behind the second rotating cleaning body 3d, and rollers 3e and 3f are provided to support the suction box 3a parallel to the ground.

The suction port connector 3b is provided with a first connection tube 3g rotatably connected in the front-rear direction with respect to the suction box 3a, and a first connection tube 3g rotatably connected in the left-right direction with respect to the first connection tube 3g 2 Connect the tube 3h.

The first connecting pipe 3g is configured to be rotatable (in the vertical direction) from a state slightly parallel to the ground (cleaning surface) until it becomes a state slightly vertical. That is, by rotating the first connecting tube 3g relative to the suction box 3a with the shaft 3i as a fulcrum, the second connecting tube 3h can be slightly parallel to the ground and perpendicular to the ground. Rotate between.

The second connecting pipe 3h is configured to be rotatable in the left-right direction (the direction perpendicular to the paper surface in FIG. 41) relative to the first connecting pipe 3g. With this, for example, it is possible to fall the body 10 toward a state slightly parallel to the ground from the state where the body 10 is set slightly perpendicular to the ground.

In addition, at the second connection pipe 3h, a power supply terminal 3j for supplying power from the battery 60 is provided. In addition, at the second connecting pipe 3h, a connecting pipe 3k connected to the suction port 15 of the cleaner body 1 is formed.

In addition, at the second connecting pipe 3h, a protruding portion 3m protruding forward in the axial direction of the connecting pipe 3k is formed at the front end portion. In addition, on the upper surface of the mouthpiece box 3a, a contact surface 3n for contacting the front end of the protrusion 3m is formed.

As shown by the imaginary line in FIG. 41, when the suction port 3b is raised toward the front, by protruding the front end of the protrusion 3m and touching the abutment surface 3n, the forward rotation of the suction port 3b is performed limit.

As shown in FIG. 42, in the electric vacuum cleaner 100, when the rotation of the suction port joint 3b is restricted, the center of gravity Ga of the cleaner body 1 is located on the axis 3i passing through the suction port joint 3b (the first connection pipe 3g) Lead straight (F). This makes it possible to make the electric vacuum cleaner 100 self-supporting.

In addition, as to whether the electric vacuum cleaner 100 can be made independent, it also changes with the width of the front and back directions of the suction box 3a of the suction port body 3, so it is not limited by the positions of the shaft 3i and the center of gravity Ga By.

Next, the quilt suction port will be described with reference to FIGS. 43 to 48. Figure 43 is a side view showing the quilt suction port, Figure 44 is a bottom view showing the quilt suction port, and Figure 45 is a pair Fig. 46 is a cross-sectional view showing the quilt suction port when the joint is lying down, and Fig. 46 is a cross-sectional view showing the quilt suction port when the joint is upright. The side view showing the electric vacuum cleaner in the state shown in FIG. 48 is a side view showing the upright electric vacuum cleaner with the quilt suction port installed.

As shown in FIG. 43, the quilt suction port 6 is composed of a suction port body 6a, a rotating body 6b, and a joint 6c.

The suction port body 6a is provided with a body box 6d that houses the rotating body 6b, and a connection portion 6e that rotatably connects the joint 6c on the upper surface of the body box 6d. In addition, the main body box 6d is provided with an intermediate portion 6f extending linearly toward the front-rear direction, a curved portion 6g before the intermediate portion 6f and a curved portion 6g before bending upward, and a position behind the intermediate portion 6f The curved portion 6h after being curved toward the upper side. In addition, the main body box 6d is formed so as to be front-rear symmetrical with the center portion ST1 in the front-back direction as a boundary.

The rotating body 6b is a part of the rotating body 6b (a region smaller than a semicircle and a smaller area) protruding downward with respect to the lower surface 6i of the body box 6d. In addition, a plurality of rotating bodies 6b are formed in the front-rear direction. In addition, although the case where three rotating bodies 6b are provided is described as an example, the system is not limited to three, and may be four or more, or two or less. In addition, the three rotating bodies 6b are arranged rearward with respect to the central portion ST1.

As shown in FIG. 44, the body box 6d is viewed as a horizontally long and slightly rectangular shape when viewed from a plane, at a position 6i below the body box 6d, It is formed with a horizontally elongated slightly rectangular opening 6j which is smaller than the main body box 6d by one circle.

The rotating body 6b is arranged so as to extend from one end in the left-right direction of the opening 6j to the other end. Further, at the rotating body 6b, a plate-shaped blade portion 6k is formed to protrude toward a plurality of directions, and the direction of the blade is changed every time a certain length is spaced in the axial direction.

In addition, the quilt suction port 6 is constructed so as to be able to clean the entire body. Therefore, under the main body box 6d, at a plurality of places around the opening 6j, holes 6v for drainage are formed.

As shown in FIG. 45, the lower surface 6m of the curved portion 6g (the lower portion of the front surface of the suction port body 6a) before the body box 6d is curved more upward than the opening 6j (lower surface of the middle portion 6f) And was formed. In addition, the tip (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 bent portion 6h (rear portion of the lower surface of the mouthpiece body 6a) behind the body box 6d is formed so as to be bent more upward than the opening 6j (lower surface of the intermediate portion 6f). In addition, the tip (rear end) P20 of the lower surface 6n is positioned higher than the upper end of the rotating body 6b.

At the connecting portion 6e of the mouthpiece main body 6a, a bearing portion 6q that supports the rotation shaft 6p of the joint 6c rotatably is formed. At the rotating shaft 6p, when the joint 6c is rotated upward, an abutting portion 6u that abuts against the opening edge 6t of the connecting portion 6e is formed. Further, at the rotating shaft 6p, there is formed a contact portion 6s that contacts the opening edge 6r of the connecting portion 6e when the joint 6c is turned downward.

The drain hole 6v is formed at the lower end of the front curved portion 6g and the lower end of the rear curved portion 6h.

With this, at the quilt suction port 6, when the joint 6c is laid down to the ground (cleaned surface) side, as shown in FIG. 45, it is configured to face the lower surface of the suction port body 6a (is formed The surface of the opening 6j) becomes γ1 (for example, 15 degrees). In addition, if the angle is smaller than γ1 (for example, if it is less than 15 degrees), when the quilt suction port 6 is retracted, the front part of the suction port body 6a easily floats.

As shown in FIG. 46, at the quilt suction port 6, when the joint 6c is erected so as to be farthest from the ground (the surface to be cleaned), it is configured to face the lower surface of the suction port body 6a (quilt The surface where the opening 6j is formed) becomes γ2 (for example, 50 degrees). In addition, if the angle is larger than γ2 (for example, if it exceeds 50 degrees), it becomes easy to drill into the quilt, which hinders the smooth movement of the quilt suction port 6.

As shown in FIG. 47, by setting the angle with respect to the lower surface of the suction nozzle body 6a to γ1, when the cleaner body 1 is used as a hand-held type, the dust box 2 and the body portion 10 become incompatible with cotton. Being contacted, it becomes possible to move the cleaner body 1 forward and backward smoothly.

As shown in FIG. 48, by setting the angle with respect to the lower surface of the suction port body 6a to γ2, it is possible to prevent the force of drilling into the quilt from being strongly applied, so that the quilt suction port 6 can be oriented before Later it moved smoothly.

In this way, at the quilt suction port 6, since the lower surface 6m of the suction port body 6a is bent more upward than the opening 6j, when advancing the quilt suction port 6, the lower 6m follows the surface of the quilt The creases of the paper can go forward, and can overcome the unevenness of the surface of the quilt. In addition, since the lower surface 6n of the suction port body 6a is curved more upward than the opening 6j, when the quilt suction port 6 is retracted, the same is achieved by following the crease on the surface of the quilt by the lower surface 6n , And can overcome the unevenness of the surface of the quilt. With this, the situation in which the quilt suction port 6 is hooked on the quilt 6 can be suppressed. In addition, even if the rechargeable electric vacuum cleaner 100 with a weak suction force is applied, it can be sucked well.
