The handy type electric vacuum cleaner according to claim 6, wherein the vacuum cleaner main body is provided with a hook receiver for hooking the removed extension pipe and a locking hook provided on the suction tool. is there.

  According to an eighth aspect of the present invention, one end side of an electric cord for supplying electric power to the electric blower is embedded in the sub handle, and the one end side of the electric cord is in the use of the sub handle. When the vacuum cleaner main body is erected, it is in a state of extending in the protruding direction of the sub handle while avoiding the other protruding surface of the sub handle. 8. The handy type vacuum cleaner according to claim 6, further comprising a cord extending direction adjusting member.

According to the first aspect of the present invention, a handy type electric vacuum cleaner having a vacuum cleaner body that can be operated by hand, an extension pipe extending forward from the vacuum cleaner body, and a suction tool attached to a tip of the extension pipe. In the machine, in the vacuum cleaner main body, the main body including the heavy electric fan is the center of gravity.
On the peripheral surface of the main body, a main handle is provided at a predetermined angular position, and a sub handle is provided at an angular position that is 180 ° apart from the angular position where the main handle is provided. The main handle and the sub handle are both provided so as to project outward from the peripheral surface of the main body.

A connecting pipe is provided integrally with the sub handle on the front extension line of the sub handle. In the connecting pipe, an extension pipe can be connected to the tip, and the rear end is curved by approximately 90 °, and the connecting pipe guides air and dust to the dust collecting case of the main body.
Here, the main handle and the sub handle are disposed symmetrically with the main body serving as the center of gravity interposed therebetween. In this case, regardless of which handle is gripped, the main body comes below the gripped handle due to the weight of the electric blower. Thereby, since the center of gravity of the cleaner body is located below the hand holding the handle, the cleaner body can be moved in a stable state.

  For example, when the area to be cleaned on the floor surface is moved from a wide area to a narrow area (or vice versa), if one of the main handle and the sub handle is changed from one to the other, the electric blower Due to its own weight, the main body is quickly arranged below the gripped handle. Thereby, the handle can be smoothly changed in a stable state.

As a result, usability can be improved.
According to the invention described in claim 2, the extension pipe is connected to the tip of the connection pipe, and in this state, the sub handle, the connection pipe and the extension pipe extend in a straight line. For this reason, when the main handle is changed to the sub handle, the main body portion is rotated downward by the weight of the electric blower around the sub handle, the connection pipe, and the extension pipe, and quickly moves below the sub handle. As a result, the main handle can be smoothly switched from the main handle to the sub handle in a stable state, and it is easy to use.

  According to the invention of claim 3, in the suction tool, the main suction port is formed on the bottom surface of the housing, the sub suction port is formed on the front surface, and the bend is connected to the housing. The bend is rotatable around a connecting portion with the housing, and is attached to the tip of the extension pipe. Therefore, when the electric blower generates a suction force, dust is sucked into the housing from the main suction port or the sub suction port, and is collected in the dust collecting case after passing through the bend, the extension pipe, and the connection pipe.

  The suction tool can be switched between a basic posture in which the main suction port faces the floor surface and an inverted posture in which the sub suction port faces the floor surface. Therefore, in a basic posture, dust in a wide area of the floor can be efficiently sucked into the housing from the main suction port. On the other hand, since the suction tool can be thinned in the horizontal direction in the inverted posture, the suction tool in the inverted posture is inserted into the gap between the wall surface of the room and the furniture, or the gap between the furniture and the furniture, and the floor in these gaps. Dust in a narrow area can be sucked into the housing from the sub suction port. That is, by switching the posture of the suction tool between the basic posture and the inverted posture, the handy type vacuum cleaner can clean both a wide area and a narrow area on the floor surface, which is convenient.

According to invention of Claim 4, the suction tool contains the shutter and the roller provided rotatably on the outer surface of the shutter.
Since the shutter closes the sub suction port in the basic posture, dust on the floor surface can be efficiently sucked into the housing from the main suction port facing the floor surface. In addition, for example, when the suction tool is to be moved along the wall surface in the room, the roller touches the wall surface and rolls, so that the suction tool can be moved smoothly and is convenient.

On the other hand, since the shutter opens the sub suction port in the inverted posture, dust in a narrow region of the floor surface can be efficiently sucked into the housing from the sub suction port facing this region. At this time, since the roller rolls while touching the floor surface, the suction tool in the inverted posture can be smoothly moved on the floor surface, which is convenient.
According to the fifth aspect of the present invention, the suction tool takes a basic posture while holding the main handle, and the suction tool takes an inverted posture while holding the sub handle.

Here, since the main handle and the sub handle are disposed symmetrically with the main body portion serving as the center of gravity interposed therebetween, the handles can be smoothly changed in a stable state. Therefore, if the main handle is gripped, the suction tool smoothly assumes the basic posture, and if the sub handle is gripped, the suction tool smoothly assumes the inverted posture, which is convenient.
In particular, since the sub handle, the connecting pipe and the extension pipe extend in a straight line, the main handle can be smoothly changed from the main handle to the sub handle. It becomes an inverted posture smoothly and is even easier to use.

  According to the sixth aspect of the present invention, the cleaner body includes a substantially circular rear end surface formed by the rear end of the main body portion, and a one-side stretch projecting outward from the rear end surface of the main body portion by the rear end of the main handle. It has a projecting surface and the other projecting surface projecting from the rear end surface of the main body by the rear end of the sub handle. The other projecting surface projects in a direction 180 ° away from the one projecting surface, and the substantially circular rear end surface, the one projecting surface, and the other projecting surface form a flat surface.

In this case, since the flat surface is long and flat along the alignment direction of the main handle, the main body portion, and the sub handle, when the cleaner body is placed on the floor so that the flat surface faces the floor, the cleaner body is A stable posture can be maintained without falling in the arrangement direction.
According to the seventh aspect of the present invention, the extension pipe and the suction tool can be removed from the cleaner body, and the cleaner body can be erected with the flat surface of the cleaner body facing the floor. At this time, the cleaner body can maintain a stable posture. The vacuum cleaner main body is provided with a hook receiver for hooking the removed extension pipe and the hook provided on the suction tool. The extension pipe and suction tool are fixed to the main body of the machine, and the handy vacuum cleaner can be stored compactly, making it easy to use.

According to the invention described in claim 8, one end of the electric cord for supplying electric power to the electric blower is embedded in the sub handle. Moreover, the cord extension direction adjusting member is provided in the handy type vacuum cleaner.
The cord extension direction adjusting member causes one end of the electric cord to extend backward from the other extension surface of the sub handle when in use, and when the cleaner body is erected, the other extension surface of the sub handle is extended. Avoiding it, it will be in the state of extending in the direction of the sub handle. Therefore, when the vacuum cleaner main body is erected, it can be prevented that one end side of the electric cord extends from the other overhanging surface and hits the floor so that the vacuum cleaner main body is inclined and the posture of the vacuum cleaner main body becomes unstable.

The long hole 32 is for passing the finger of the hand holding the main handle 30. The entire main handle 30 has a substantially D shape that bulges upward (in the radial direction of the main body portion 5) in an arc shape. That is, the main handle 30 is provided at a predetermined angular position on the peripheral surface (circumferential surface) of the main body 5 so as to project outward from the peripheral surface. A switch 33 that is operated to control the operation of the motor 15 is provided on the front portion of the upper side surface of the main handle 30.

The rear side surface 30A of the main handle 30 is a flat surface, is continuous from the upper side with respect to the rear end surface 5C of the main body 5 and is flush with the rear end surface 5C. In other words, the cleaner body 2 has a rear side surface 30 </ b> A that forms one overhanging surface projecting outward from the rear end surface 5 </ b> C of the main body portion 5 by the rear end of the main handle 30.
The sub handle 31 is integrally provided on the lower portion of the circumferential surface of the main body 5 and is positioned on the opposite side of the main handle 30 with the electric blower 6 (or the central axis J of the main body 5) interposed therebetween. is doing. In other words, the sub handle 31 is provided so as to project outward from the peripheral surface at an angular position of the peripheral surface of the main body 5 that is 180 ° apart from the angular position where the main handle 30 is provided. The main handle 30 and the sub handle 31 are symmetrical with respect to the electric blower 6 (the central axis J of the main body 5).

  The sub handle 31 is substantially L-shaped. Specifically, the sub handle 31 is orthogonal to the straight portion 31A extending linearly from the rear end of the straight portion 8A of the connecting pipe 8 to the rear side along the straight portion 8A, and from the rear end of the straight portion 31A to the straight portion 31A. And an orthogonal portion 31 </ b> B integrally extending from the lower side to the rear end portion of the main body portion 5. The connecting portion between the straight portion 31A and the orthogonal portion 31B is rounded.

Here, on the basis of the connecting pipe 8, the connecting pipe 8 is provided integrally with the sub handle 31 on the front extension line of the straight portion 31 </ b> A of the sub handle 31.
The L-shaped sub handle 31 and the lower portion of the circumferential surface of the main body 5 define a long hole 34 through which the finger of the hand holding the main handle 30 passes. The long hole 34 is long along the central axis J of the main body 5.

  The rear side surface 31C of the orthogonal portion 31B of the sub handle 31 is a flat surface, is continuous from the lower side with respect to the rear end surface 5C of the main body 5, and is flush with the rear end surface 5C. In other words, the cleaner body 2 has a rear side surface 31 </ b> C that forms the other projecting surface that projects outward from the rear end surface 5 </ b> C of the main body 5 by the rear end of the sub handle 31. Here, since the main handle 30 and the sub handle 31 are symmetrical with respect to the electric blower 6 (main body 5), the rear side surface 31C of the sub handle 31 is separated from the rear side surface 30A of the main handle 30 by 180 °. It protrudes in a drooping direction.

As described above, since the rear side surface 30A of the main handle 30 and the rear end surface 5C are flush with each other, the rear side surface 31C of the sub handle 31, the rear side surface 30A of the main handle 30, and the rear end surface 5C of the main body 5 are provided. Is flat and forms a flat surface 35 in a unified state.
In addition, one end side 37 </ b> A of an electrical cord 37 is connected to the cleaner body 2 in order to supply external power to electrical components such as the electric blower 6. One end side 37 </ b> A of the electric cord 37 is embedded in the straight portion 31 </ b> A of the sub handle 31. Further, a bushing 39 is provided on one end side 37A, and the bushing 39 is also embedded in the straight portion 31A. That is, since the bushing 39 is configured not to protrude from the sub handle 31, the vacuum cleaner body 2 (the vacuum cleaner 1) is reduced in size, and when the sub handle 31 is gripped, Bushing 39 does not get in the way.

A notch 38 (cord extending direction adjusting member) is continuously formed at the lower end portion of the rear side surface 31C of the orthogonal portion 31B and the substantially rear half of the lower side surface of the linear portion 31A. The electric cord 37 protrudes from the notch 38. An electric plug (not shown) is connected to the other end of the electric cord 37. When this electric plug is connected to an outlet (not shown), the electric cord 37 is connected to an electric component such as the electric blower 6 and the like. Can supply power.
<Extension pipe>
Referring to FIG. 1, the extension tube 3 is a substantially circular tube extending linearly, and can be divided into a first tube 40 on the cleaner body 2 side and a second tube 41 on the suction tool 4 side. The lengths of the first tube 40 and the second tube 41 are substantially the same. The rear end portion of the second tube 41 is accommodated inside the front end portion of the first tube 40. In this state, the first tube 40 and the second tube 41 are coaxial. By accommodating the second pipe 41 in the first pipe 40, the extension pipe 3 can be expanded and contracted to change the length of the extension pipe 3.

  A concave portion 42 is formed at one place on the outer peripheral surface of the rear end portion of the first tube 40 (see FIG. 8 described later). As will be described later, the recess 42 receives the hook 9B (see FIG. 2) of the release lever 9 at the tip 8B of the connection pipe 8 of the cleaner body 2. An adjustment button 43 is provided on the upper side surface of the front end portion of the first tube 40. The adjustment button 43 is operated when the extension tube 3 is expanded and contracted.

  A plurality of concave portions 44 are formed on the upper side surface of the second pipe 41 so as to be arranged in parallel at intervals in almost the entire region in the length direction (see FIG. 1B). A claw (not shown) provided in the first tube 40 is caught in any of the recesses 44, and in this state, the expansion and contraction of the extension tube 3 is restricted. When the adjustment button 43 is pressed, the claw (not shown) can be removed from the recessed portion 44 that has been hooked so far, and the extension tube 3 can be expanded and contracted. When the adjustment button 43 is released after the extension tube 3 is expanded or contracted to have an arbitrary length, the above-described claw (not shown) is caught in the nearest recess 44, so that the extension tube 3 can be extended to an arbitrary length. Can be maintained.

A removal button 45 is provided on the upper side surface of the front end portion of the second tube 41. The removal button 45 is operated when removing the suction tool 4 from the extension pipe 3.
Such an extension pipe 3 is connected to the tip 8B (the cleaner body 2) by the rear end of the first pipe 40 being fitted into the tip 8B of the connection pipe 8 of the cleaner body 2. Is done. In a state where the extension tube 3 is connected to the tip 8B, a hook 9B (see FIG. 2) of the release lever 9 at the tip 8B of the connection tube 8 is placed in the recess 42 (see FIG. 8) at the rear end of the first tube 40. Thus, the extension tube 3 is fixed (locked) to the vacuum cleaner body 2 so as not to be detached. When the release button 9A of the release lever 9 is pressed, the release lever 9 swings and the hook 9B is released from the recess 42, so that the extension pipe 3 is unlocked from the cleaner body 2, and the extension pipe 3 is removed from the vacuum cleaner. It can be removed from the main body 2.

As shown in FIG. 1, in a state where the extension tube 3 is coupled to the tip 8 </ b> B of the connection tube 8, the sub handle 31, the connection tube 8 and the extension tube 3 extend in a straight line.
<Suction tool>
The suction tool 4 includes a housing 50 and a bend 51.
The housing 50 has a box shape that is long (wide) in the width direction and flat and flat in the vertical direction. A main suction port 52 that is long in the width direction is formed on the front side of the bottom surface 50 </ b> A of the housing 50, and a sub suction port 53 that is long in the width direction is formed on the front surface 50 </ b> B of the housing 50. The sub suction port 53 is continuous from the front side with respect to the main suction port 52. The main suction port 52 and the sub suction port 53 communicate with the inside of the housing 50.

  A shutter 54 is provided on the front surface 50 </ b> B of the housing 50. The shutter 54 has a plate shape that is long in the width direction. The shutter 54 is curved so as to bulge in an arc shape toward the front upper side as viewed from the width direction. Rollers 55 are provided at both ends in the width direction of the front side surface (outer surface) of the shutter 54. The roller 55 has a cylindrical shape extending to the front upper side, and the tip end (front upper end) is rounded. The roller 55 is rotatable about an axis (not shown) extending to the front upper side.

The shutter 54 covers the sub suction port 53 from the front upper side so as to be opened and closed. In FIG. 1, the shutter 54 closes the sub suction port 53. In the opened shutter 54, the rear portion is accommodated in the housing 50 (not shown) so as to be hidden under the front end portion of the top wall 50C of the housing 50.
Here, the shutter 54 is biased by a biasing member (a spring or the like) so as to close. Therefore, as shown in FIG. 3, by pressing the roller 55 against the wall W, the shutter 54 can be opened against the urging force of the urging member. Conversely, when the roller 55 is separated from the wall W, the shutter 54 is quickly closed by the urging force of the urging member as shown in FIG.

  As shown in FIG. 1A, a connection tube 56 is attached to the center in the width direction of the rear surface of the housing 50. The connecting cylinder 56 has a substantially cylindrical shape having a central axis extending in the front-rear direction, is inserted through the rear surface of the housing 50 from the rear, and is supported by the housing 50 so as to be rotatable about the central axis described above. , Part of the housing 50. The inside of the connection tube 56 communicates with the housing 50. The rear end surface of the connecting tube 56 and one place on the outer peripheral portion are continuously cut out to form a cutout portion 56A.

The bend 51 has a tubular shape elongated in the front-rear direction in FIG. 1A, and the front end thereof is formed in a substantially spherical shape. The front end of the bend 51 is inserted through the notch 56A of the connection tube 56 of the housing 50 from behind, whereby the bend 51 is supported by the connection tube 56 (housing 50).
Specifically, in the bend 51, the front end is connected to the housing 50, and the rear end protrudes rearward from the housing 50. In this state, the bend 51 is rotatable with respect to the connection tube 56 with the front end as a fulcrum. In FIG. 1A, the bend 51 is rotatable up and down. Since the connecting cylinder 56 is rotatable about a central axis extending in the front-rear direction, the bend 51 rotates with respect to the connecting cylinder 56 and the central axis extending in the front-rear direction together with the connecting cylinder 56. Can be turned around. That is, the bend 51 can be rotated around the connection cylinder 56 that is a connecting portion with the housing 50.

The inside of the bend 51 communicates with the inside of the housing 50 through the inside of the connection cylinder 56. The bend 51 is attached to the distal end of the extension pipe 3 (the front end of the second pipe 41) at the rear end.
A rotating brush 57 is provided in the housing 50. The rotary brush 57 is supported by the left and right side walls of the housing 50 so as to be longitudinal in the width direction. The bristles of the rotating brush 57 face both the main suction port 52 and the sub suction port 53. A motor and a turbine are provided in the housing 50 (not shown). When the motor is driven by receiving electric power from the cleaner body 2 or the turbine is rotationally driven by air sucked into the housing 50 as will be described later, the rotating brush 57 is driven by the motor or the turbine. And rotate.

FIG. 3 is a right side view of the cleaner 1 in a state where the shutter 54 of the suction tool 4 is opened. 4A is a side view of the cleaner 1 in a state where the suction tool 4 is in an inverted posture, and FIG. 4B is a rear view of the cleaner 1 in a state where the suction tool 4 is in an inverted posture. is there.
Such a suction tool 4 can be switched between a basic posture shown in FIGS. 1 and 3 and an inverted posture shown in FIG. 4. When the suction tool 4 is in the basic posture, the main suction port 52 is opposed to the floor surface V from above (see FIGS. 1 and 3), and when the suction tool 4 is in the inverted posture, the sub suction port 53 is the floor. It faces the surface V from above.

If the suction tool 4 is in the basic posture when the roller 55 is not pressed against the wall W, the shutter 54 closes the auxiliary suction port 53 (see FIG. 1). On the other hand, when the suction tool 4 is in the inverted posture, the roller 55 is brought into contact with the floor surface V, so that the shutter 54 moves in the opening direction and opens the auxiliary suction port 53 (see FIG. 4).
As shown in FIG. 1, when the main handle 30 is gripped in the cleaner body 2, the main handle 30 is located at the upper end of the cleaner body 2, the body portion 5 is located directly below the main handle 30, and the sub handle 31 is located on the opposite side of the main handle 30 (the lower surface side of the cleaner body 2) with the body portion 5 interposed therebetween. In this state, the suction tool 4 takes a basic posture, and the extension pipe 3 extends obliquely to the rear upper side while being orthogonal to the longitudinal direction (width direction) of the housing 50 of the suction tool 4. At this time, in the cleaner body 2, the connection pipe 8 and the sub handle 31 extend on the extension line of the extension pipe 3.

In this state, when the main handle 30 is held and moved forward, and the suction tool 4 is pressed against the indoor wall W from the shutter 54 side as shown in FIG. 3, the roller 55 of the shutter 54 contacts the wall W. As a result, the shutter 54 is opened.
Further, in the state of FIG. 1, the main handle 30 is changed to the sub handle 31, and the sub handle 31 is slightly lifted. Then, the main body 5 and the main handle 30 above the sub handle 31 in FIG. 1 in the vacuum cleaner main body 2 have the extension pipe 3, the connecting pipe 8 and the sub handle 31 extending in a straight line as axes of the electric blower 6. It turns downward by its own weight. Strictly speaking, the portion other than the suction tool 4 in the vacuum cleaner 1 is twisted 180 ° downward about the extension pipe 3, the connection pipe 8 and the sub handle 31. Thereby, the main-body part 5 and the main handle 30 move rapidly below the sub handle 31, as shown in FIG. Therefore, the main handle 30 can be smoothly changed from the main handle 30 to the sub handle 31 in a stable state, which is convenient. Further, at the same time as the main body 5 and the main handle 30 move, the extension tube 3 rises a little while twisting in response to the sub handle 31 being slightly lifted. At this time, the rear end side of the suction tool 4 is lifted. Therefore, the posture of the suction tool 4 changes to an inverted posture, and the shutter 54 opens. At this time, the suction tool 4 in the inverted posture, the extension pipe 3 and the cleaner body 2 are arranged on the same vertical plane H (see FIG. 4B).

When the sub handle 31 is replaced with the main handle 30, the main body 5 and the sub handle 31 rotate downward together with the extension pipe 3, the connecting pipe 8, and the sub handle 31, and as shown in FIG. It is disposed below the handle 30. At the same time, the posture of the suction tool 4 returns from the inverted posture to the basic posture.
As described above, the suction tool 4 takes the basic posture while the main handle 30 is gripped, and the suction tool 4 takes the inverted posture while gripping the sub handle 31. When the main handle 30 is changed to the sub handle 31, the main body 5 and the main handle 30 are positioned below the sub handle 31, and when the sub handle 31 is changed to the main handle 30, the main body 5 and the sub handle 31 are main. Located below the handle 30.
<Cleaning with a vacuum cleaner>
As shown in FIG. 1, in a state where the suction tool 4 is in the basic posture and the shutter 54 is closed, an electric plug (not shown) of the electric cord 37 is connected to an outlet (not shown) to switch the main handle 30. When 33 is turned ON, electric power is supplied to the electric blower 6 (motor 15), and the electric blower 6 generates a suction force (see FIG. 2). This suction force acts inside each of the dust collecting portion 7, the connecting pipe 8, the extension pipe 3, the bend 51, and the housing 50.

As a result, a suction force also acts on the main suction port 52 of the bottom surface 50 </ b> A of the housing 50, so that air outside the housing 50 is sucked into the housing 50 from the main suction port 52.
Therefore, if the main handle 30 is gripped and the suction tool 4 is moved on the floor surface V with the main suction port 52 facing the floor surface V, dust on the floor surface V is attracted from the main suction port 52. It rides on the air sucked into the housing 50 and is sucked into the housing 50 from the main suction port 52. Thereafter, the dust and air that have flowed into the housing 50 flow into the connecting pipe 8 of the cleaner body 2 through the bend 51 and the extension pipe 3.

  Referring to FIG. 2, the dust and air that have passed through connecting pipe 8 are collected through the communication port 11 of the main body 5 and the intake port 18 </ b> B of the dust collecting case 18, as indicated by solid thick arrows. It flows into the case 18 and reaches the gap X described above (the gap X between the outer peripheral surface of the guide member 19 and the inner peripheral surface of the dust collecting case 18). That is, the connecting pipe 8 guides air and dust to the dust collecting case 18.

The air that has reached the gap X passes through the gap X while turning around the guide member 19 as indicated by the broken thick arrow, and corresponds to the substantially front half of the internal space of the dust collecting case 18. It reaches the dust chamber Y and flows to the rear side while turning in the dust chamber Y.
The air that has flown rearward through the dust collection chamber Y passes through the through hole 22 of the partition wall 19D of the guide member 19 or returns to the gap X again as indicated by the one-dot chain line thick arrow. By passing through the through-hole 22 or the like, the gas flows into the inside of the guide member 19 (a region behind the partition wall 19D). In order to allow the air that has flowed into the dust collection case 18 to once flow into the dust collection chamber Y and then pass through the through hole 22, the through hole 22 is formed in the guide member 19 through the intake port of the dust collection case 18. It is formed at a position away from the position facing 18B.

The air that has flowed into the guide member 19 passes through the filter 21 and reaches the inside of the holder 20 as indicated by a two-dot chain line, and then the motor 12 is opened from the opening 12 on the front surface of the motor cover 16. After being sucked into the cover 16, it passes through the discharge port 17 and is discharged from the exhaust port 14 on the rear end surface 5 </ b> C of the main body 5 to the outside of the machine.
As described above, the size of the gap X in the radial direction of the dust collecting case 18 (guide member 19) is constant in the portion that coincides with the cylindrical portion 19A, but is narrow in the portion that coincides with the enlarged diameter portion 19B. Yes. That is, the gap X is narrow on the dust collection chamber Y side. Therefore, when air flows from the gap X to the dust collection chamber Y, a pressure difference is generated between the dust collection chamber Y and the gap X, with the dust collection chamber Y side being narrower in the gap X as a boundary. Thereby, the dust that flows into the dust collection case 18 together with the air and reaches the gap X is vigorously sent to the dust collection chamber Y by this pressure difference, and enters the dust collection chamber Y on the front side (the bottom of the dust collection case 18). From the side).

There may be dust that rides on the air and flows into the guide member 19, but this dust is captured by the filter 21. Further, another filter 25 is provided at the exhaust port 14, and fine dust that is not captured by the filter 21 is captured by the filter 25. The filter 25 also has a function of reducing exhaust noise.
By removing the dust collecting part 7 from the main body part 5, dust accumulated in the dust collecting chamber Y can be discarded or the filter 21 can be maintained.

  As shown in FIG. 1, in the state where the suction tool 4 is in the basic posture, the shutter 54 closes the sub suction port 53, so that the suction force can be applied only to the main suction port 52. Therefore, the dust on the floor surface V can be efficiently sucked into the housing 50 from the main suction port 52 facing the floor surface V. Further, the rotating rotary brush 57 scrapes up dust on the floor surface V from the main suction port 52. Accordingly, dust can be effectively introduced from the main suction port 52 into the housing 50 and stored in the dust collection chamber Y of the dust collection case 18.

  On the other hand, as shown in FIG. 3, when the suction tool 4 is pressed against the wall W, the shutter 54 opens the auxiliary suction port 53. In this case, since the suction force also acts on the sub suction port 53, dust can be sucked into the housing 50 from the sub suction port 53. In this case, since the sub suction port 53 faces the wall W, dust adhering to the wall W can be sucked into the housing 50 from the sub suction port 53. Further, the brush bristles facing the sub suction port 53 in the rotating rotary brush 57 scrape the dust on the wall W into the sub suction port 53, so that the dust adhering to the wall W is efficiently sucked into the housing 50.

The dust sucked into the housing 50 is stored in the dust collecting chamber Y (see FIG. 2) of the dust collecting case 18 as described above. Further, dust on the floor surface V at the wall W (at the wall) is sucked into the housing 50 from the main suction port 52 and collected in the dust collecting chamber Y.
With the suction tool 4 pressed against the wall W in this manner and the shutter 54 opened, the main handle 30 is gripped and the suction tool 4 is moved laterally along the wall W. Then, the roller 55 of the shutter 54 touches the wall surface of the wall W and rolls. Thereby, by being guided by the roller 55, the suction tool 4 can be smoothly moved laterally along the wall W, which is convenient. When the suction tool 4 moves laterally, the dust on the wall W and the dust on the wall are sucked into the housing 50 and stored in the dust collection chamber Y. Note that the suction tool 4 in the basic posture with the shutter 54 closed can be placed along the wall W. At this time, the roller 55 touches the wall surface of the wall W and rolls, so that the suction tool 4 moves to the wall W. It can be smoothly moved laterally along.

Further, when the suction tool 4 is in the basic posture (see FIGS. 1 and 3), if the main handle 30 is changed to the sub handle 31 as described above, the suction tool 4 is in an inverted posture as shown in FIG. . When the suction tool 4 is in an inverted posture, the roller 55 comes into contact with the floor surface V and is pushed from below by the floor surface V, whereby the shutter 54 is opened.
When the suction tool 4 is in the inverted posture, in the housing 50 that is wide and flat in the vertical direction in the basic posture (see FIGS. 1 and 3), the sub suction port 53 side is the bottom surface and the bend 51 side is the top surface. Thus, the housing 50 is thinned in the lateral direction (horizontal direction) (the facing area of the housing 50 with respect to the floor surface V is reduced). Therefore, the housing 50 can be inserted into a narrow region on the floor surface V such as a gap between the wall surface of the wall W and the furniture or a gap between the furniture and the furniture.

At this time, since the shutter 54 opens the sub suction port 53, the dust in the narrow region of the floor surface V can be efficiently sucked into the housing 50 from the sub suction port 53 facing this region. it can. At this time, since the roller 55 touches and rolls on the floor surface V, the suction tool 4 in an inverted posture can be smoothly moved on the floor surface V, which is convenient.
And the dust in the narrow area | region suck | inhaled in the housing 50 from the sub suction port 53 is collected in the dust collection chamber Y (refer FIG. 2) of the dust collection case 18, as mentioned above.

  Thus, in the basic posture, dust in a wide area of the floor surface V can be efficiently sucked into the housing 50 from the main suction port 52 (see FIGS. 1 and 3). On the other hand, since the suction tool 4 can be thinned in the lateral direction in the inverted posture, the suction tool 4 in the inverted posture is inserted into the gap between the wall surface of the room and the furniture or the gap between the furniture and the furniture. The dust in the narrow area of the floor surface V can be sucked into the housing 50 from the sub suction port 53 (see FIG. 4). That is, by switching the posture of the suction tool 4 between the basic posture and the inverted posture, the vacuum cleaner 1 can clean both a wide region and a narrow region on the floor surface V, and is convenient.

  Further, the main handle 30 and the sub handle 31 are arranged symmetrically with the main body portion 5 serving as the center of gravity interposed therebetween, so that no matter which handle is gripped, the weight of the electric blower 6 causes the lower portion of the gripped handle to be held. The main body 5 comes. Thereby, since the center of gravity of the cleaner body 2 is located below the hand holding the handle, the cleaner body 2 can be moved in a stable state.

  In addition, when the area to be cleaned on the floor surface V is moved from a wide area to a narrow area (or vice versa), if one of the main handle 30 and the sub handle 31 is changed from one to the other, the electric blower The main body 5 is quickly placed under the gripped handle by its own weight. Thereby, the handle can be smoothly changed in a stable state. As a result, if the main handle 30 is gripped, the suction tool 4 smoothly assumes the basic posture, and if the sub handle 31 is gripped, the suction tool 4 smoothly assumes the inverted posture.

In particular, since the sub handle 31, the connecting pipe 8, and the extension pipe 3 extend in a straight line, the main handle 30 can be smoothly transferred from the main handle 30 to the sub handle 31. Therefore, if the sub handle 31 is gripped, The suction tool 4 is in the inverted posture more smoothly (see FIG. 4).
As described above, the same suction tool 4 can continuously clean a wide area and a narrow area on the floor surface V without interruption, thereby improving usability.
<Storage of vacuum cleaner>
FIG. 5 is a perspective view of the vacuum cleaner 1 in the housed state. FIG. 6 is a side view of the cleaner 1 in the housed state. FIG. 7 is a plan view of the vacuum cleaner 1 in the housed state. FIG. 8 is a side view of the modified vacuum cleaner 1 in the housed state.

  As shown in FIG. 1 (a), the outer peripheral surface of the front end portion (end portion on the suction tool 4 side) of the extension pipe 3 is bent to the suction tool 4 side in relation to the storage of the cleaner 1. A stop hook 60 is provided. The locking hook 60 may be provided on the suction tool 4. Further, as shown in FIG. 5, a hook receiver 61 for hooking a locking hook 60 is integrally provided on each of the left outer peripheral surface and the right outer peripheral surface on the tip 8B side of the connecting pipe 8 of the cleaner body 2. It has been. That is, the pair of hook receivers 61 are provided so as to be symmetric with respect to the connection pipe 8. Each hook receiver 61 has a box shape having an open portion 61 </ b> A on at least the tip 8 </ b> B side of the connection pipe 8.

As described above, when the release button 9A (see FIG. 1) of the connecting pipe 8 is pressed, the lock of the extension pipe 3 with respect to the cleaner body 2 is released, so that the suction tool 4 and the extension pipe in an integrated state are released. 3 can be removed from the cleaner body 2.
After removing the suction tool 4 and the extension pipe 3 from the cleaner body 2, the flat surface 35 (see FIGS. 1 to 4) that has been located at the rear end of the cleaner body 2 until now is placed on the floor (floor surface V). The vacuum cleaner main body 2 is erected so as to be vertically long, facing from above. At this time, since the flat surface 35 is in surface contact with the floor surface V, the standing cleaner body 2 can maintain a stable posture (see also FIG. 6).

  Then, after the suction tool 4 is positioned at the lower end so that the extension pipe 3 extends substantially vertically upward from the suction tool 4, the locking hook 60 of the extension pipe 3 is connected to the open portion 61 </ b> A of any hook receiver 61. And is hooked on the hook receiver 61 from above. Then, the suction tool 4 and the extension pipe 3 are fixed to the cleaner body 2 in a state where the extension pipe 3 extends substantially vertically, and the cleaner 1 enters the housed state. That is, by hooking the locking hook 60 on the hook receiver 61, the extension pipe 3 and the suction tool 4 can be fixed to the standing cleaner body 2, and the cleaner 1 can be stored in a compact manner. .

  At this time, as shown in FIG. 6, in the cleaner body 2, the flat surface 35 continues to be in surface contact with the floor surface V, and the lower end portion of the suction tool 4 is in contact with the floor surface V. Here, since the flat surface 35 is long and flat along the arrangement direction of the main handle 30, the main body 5 and the sub handle 31, the vacuum cleaner main body 2 is placed so that the flat surface 35 faces the floor (floor surface V). Even when placed on the floor, the vacuum cleaner main body 2 can maintain a stable posture without falling in the arrangement direction (see the thick solid arrow in FIG. 7). On the other hand, since the lower end part of the suction tool 4 and the flat surface 35 of the cleaner body 2 are in contact with the floor surface V, the cleaner is moved in the direction orthogonal to the arrangement direction (see the thick broken line arrow in FIG. 7). The main body 2 (the entire vacuum cleaner 1) does not fall down. That is, with such a configuration, the posture of the vacuum cleaner 1 in the housed state can be stabilized.

As shown in FIG. 8, the hook receiver 61 is provided on the outer peripheral surface of the connecting pipe 8 other than the left outer peripheral surface and the right outer peripheral surface (the lower outer peripheral surface when the cleaner 1 is in the posture of FIG. 1). Also good. Moreover, in the cleaner 1 in the housed state, the extension pipe 3 may be contracted (see FIGS. 5 to 8), or the extension pipe 3 may be extended.
FIG. 9 is a side view of the cleaner body 2 in a state of being erected on the floor surface V, and a part thereof is shown in cross section. FIG. 10A is a side view of the cleaner body 2 according to the modification, and a part thereof is shown in cross section. FIG. 10B is a side view of the cleaner body 2 in a state in which the cleaner body 2 according to the modification is erected on the floor surface V, and a part thereof is shown in cross section.

  With reference to FIG. 2, as described above, one end side 37 </ b> A of the electric cord 37 is embedded in the straight portion 31 </ b> A of the sub handle 31. One end side 37A of the electric cord 37 is in a sub handle via a notch 38 on the rear side surface 31C of the orthogonal portion 31B of the sub handle 31 when in use (when the cleaner body 2 is suspended and cleaned). The rear side surface 31C of the 31 extends rearward.

  On the other hand, as described above, when the cleaner body 2 is erected with the flat surface 35 of the cleaner body 2 facing the floor V from above, as shown in FIG. It is curved and extends in the lateral direction by protruding from the notch 38 in the straight portion 31A. That is, the one end side 37 </ b> A is in a state of avoiding the rear side surface 31 </ b> C of the sub handle 31 and extending in the extending direction of the sub handle 31 (direction outward from the peripheral surface of the main body 5).

Further, instead of the notch 38, a rotating member 70 (cord extending direction adjusting member) shown in FIGS. 10A and 10B can be used.
The rotating member 70 integrally includes a cylindrical portion 71 and a pipe portion 72 that extends linearly from one place on the circumferential surface of the cylindrical portion 71 in the radial direction of the cylindrical portion 71. The inside of the cylindrical part 71 and the inside of the pipe part 72 are in communication. In addition, an opening 71 </ b> A communicating with the inside of the cylindrical portion 71 is formed at a position 180 ° apart from the connecting position with the pipe portion 72 in the circumferential direction on the circumferential surface of the cylindrical portion 71. In addition, an opening 72 </ b> A communicating with the inside of the pipe portion 72 is formed at the free end portion of the pipe portion 72 opposite to the base end portion connected to the cylindrical portion 71.

In the rotating member 70, the cylindrical portion 71 is embedded in a connecting portion between the straight portion 31A and the orthogonal portion 31B in the sub handle 31. The rotation member 70 can rotate between a linear position (see FIG. 10A) and a rotation position (see FIG. 10B) around the cylindrical portion 71.
When in the straight position, the tube portion 72 of the rotating member 70 extends from the rear side surface 31C of the sub handle 31 along the extension line of the straight portion 31A, and the opening 72A of the tube portion 72 extends from the rear side surface 31C to the rear side. It faces the rear at the position protruding to the back (see FIG. 10A).

At the rotation position, the pipe portion 72 extends along the extension line of the orthogonal portion 31B, and the opening 72A of the pipe portion 72 faces the direction avoiding the rear side surface 31C (see FIG. 10B).
In the rotating member 70, one end side 37A of the electric cord 37 is accommodated. One end side 37 </ b> A passes through an opening 71 </ b> A of the cylindrical portion 71 and is connected to an electrical component (such as the electric blower 6 described above) in the cleaner main body 2, and from the opening 72 </ b> A of the pipe portion 72 to the outside of the cleaner main body 2. It is sticking out.

As shown in FIG. 10A, when the rotating member 70 is in the linear position, the one end side 37 </ b> A of the electric cord 37 extends rearward from the rear side surface 31 </ b> C of the sub handle 31 through the opening 72 </ b> A of the tube portion 72. It has become.
On the other hand, when the cleaner main body 2 is erected, the rotating member 70 is brought into contact with the floor surface V, and thus rotates to the rotating position as shown in FIG. 10B. When the rotating member 70 is in the rotating position, the one end side 37A of the electric cord 37 avoids the rear side surface 31C of the sub handle 31 through the opening 72A of the pipe portion 72, and extends the sub handle 31 as described above. It extends in the direction.

Due to these notches 38 (see FIGS. 2 and 9) and the rotating member 70, one end side 37A of the electric cord 37 extends rearward from the rear side surface 31C of the sub handle 31 when used (see FIG. 2 and FIG. 10A). On the other hand, when the cleaner body 2 is erected, the one end side 37A avoids the rear side 31C of the sub handle 31 and extends in the extending direction of the sub handle 31 (see FIGS. 9 and 10B). . Therefore, when the cleaner main body 2 is erected, the one end side 37A of the electric cord 37 extends from the rear side surface 31C and hits the floor surface V (between the rear side surface 31C and the floor surface V). It can prevent that 2 inclines and the attitude | position of the cleaner body 2 becomes unstable (refer FIG. 9 and FIG. 10B).

FIG. 11A is a perspective view of the exhaust adjustment mechanism 80 attached to the rear end surface 5C of the cleaner body 2, and FIG. 11B is a cross-sectional view of the exhaust adjustment mechanism 80. FIG. 12A is a perspective view of the slide member 81 of the exhaust adjustment mechanism 80, and FIG. 12B is a cross-sectional view of the slide member 81. FIG. 13A is a perspective view of the holding member 82 of the exhaust adjustment mechanism 80, and FIG. 13B is a cross-sectional view of the holding member 82.

An exhaust adjustment mechanism 80 shown in FIG. 11 is attached to the rear end surface 5C (see FIG. 2) of the cleaner body 2. The exhaust adjustment mechanism 80 adjusts the direction of exhaust from the exhaust port 14 of the rear end face 5C.
The exhaust adjustment mechanism 80 includes a slide member 81 shown in FIG. 12 and a holding member 82 shown in FIG.

Referring to FIG. 12, the slide member 81 has a plate shape that is long in the direction in which the main handle 30 and the sub handle 31 (see FIG. 2) are arranged on the rear end surface 5C. Note that the slide member 81 in FIG. 12 has a substantially rectangular shape, but actually, the slide member 81 may have an elliptical shape or a circular shape as long as it covers the exhaust port 14 of the cleaner body 2.
The slide member 81 is formed with a plurality of (here, five) slits 83 penetrating the slide member 81 in the thickness direction so as to be aligned in the longitudinal direction of the slide member 81. The slit 83 is long in a direction orthogonal to the longitudinal direction of the slide member 81. Each slit 83 is divided into two in the longitudinal direction by a rib 84 extending in the middle in the longitudinal direction. In the slide member 81, a portion between adjacent slits 83 forms a triangular protrusion 85 that protrudes in a triangular shape in a predetermined direction (right side in FIG. 12). In FIG. 12, four triangular protrusions 85 are formed in the slide member 81.

Referring to FIG. 13, the holding member 82 is larger than the slide member 81 and has a plate shape that is long in the arrangement direction. In the holding member 82, both end portions in a direction orthogonal to the longitudinal direction are bent in directions approaching each other, whereby the both end portions of the holding member 82 extend in parallel while being recessed in directions away from each other. A guide groove 86 is formed.
In the holding member 82, the number of triangular projections 85 (see FIG. 12) of the slide member 81 (in this case, with outlets 87 penetrating the holding member 82 in the thickness direction aligned in the longitudinal direction of the holding member 82 (here, Only 4). Each outlet 87 is long in a direction perpendicular to the longitudinal direction of the holding member 82.

  In the side surface of the holding member 82 opposite to the side where the guide groove 86 is formed (the front side surface in FIG. 13A), both end edges of the outlets 87 in the longitudinal direction approach each other. A plate-shaped guide rib 88 extending in a slanting direction is formed. That is, a pair of guide ribs 88 is provided for each outlet 87. A predetermined gap is secured between the tips of the pair of guide ribs 88 of each outlet 87.

  Referring to FIG. 11, in exhaust adjustment mechanism 80 in the completed state, slide member 81 is attached to holding member 82 from the side of holding member 82 where guide groove 86 is formed. At this time, the longitudinal directions of the slide member 81 and the holding member 82 are the same. At this time, each triangular projection 85 of the slide member 81 is fitted with play in the longitudinal direction with respect to the outlet 87 at a corresponding position in the holding member 82, and the tip of each triangular projection 85 is The gaps at the tips of the pair of guide ribs 88 of each outlet 87 are fitted with play in the longitudinal direction.

  In a state where the slide member 81 is attached to the holding member 82, in the slide member 81, one end portion 81 </ b> A (see FIG. 12A) in the direction orthogonal to the longitudinal direction is the guide groove 86 on the same side in the holding member 82. The other end 81B (see FIG. 12A) is fitted in the guide groove 86 on the same side in the holding member 82. Thus, the slide member 81 is supported by the holding member 82 so as to be slidable along the longitudinal direction thereof. The slide member 81 can slide by the amount of play of the triangular protrusion 85 at each outlet 87.

Such an exhaust adjustment mechanism 80 is attached to the rear end surface 5C (see FIG. 2) of the main body portion 5 of the cleaner body 2 from the rear side so as to close the exhaust port. In this state, in the exhaust adjustment mechanism 80, each slit 83 of the slide member 81 communicates with the exhaust port 14 from the rear side.
FIG. 14 is a cross-sectional view of the exhaust adjustment mechanism 80 when the main handle 30 is gripped. FIG. 15 is a cross-sectional view of the exhaust adjustment mechanism 80 when the sub handle 31 is gripped.

  When the main handle 30 is gripped (see FIGS. 1 and 3), as shown in FIG. 14, the exhaust adjustment mechanism 80 has a vertically long posture, and the slide member 81 has a lower limit due to its own weight. In position. At this time, each triangular protrusion 85 of the slide member 81 is located at the lower end of the corresponding outlet 87 and is in surface contact with the guide rib 88 on the lower end side of the outlet 87, while the upper end of the outlet 87 is It is separated from the guide rib 88 on the side. Thus, a predetermined flow path Z is formed between each triangular protrusion 85 and the guide rib 88 on the upper end side of the corresponding outlet 87. Each flow path Z extends obliquely downward while connecting the slit 83 adjacent to the triangular protrusion 85 from the upper side by the slide member 81 and the gap between the tips of the pair of guide ribs 88 of each outlet 87. Therefore, as shown by the thick arrows, the exhaust from the exhaust port 14 flows obliquely downward in each flow path Z, and obliquely downwards toward the outside of the machine from the gap between the tips of the pair of guide ribs 88 of each outlet 87. Discharged.

Therefore, since the exhaust discharged diagonally downward does not reach the hand holding the main handle 30 on the upper end side of the cleaner body 2, the user can comfortably hold the main handle 30 (see FIGS. 1 and 3). ).
On the other hand, when the main handle 30 is changed to the sub handle 31, as described above, the main handle 30 is positioned below the sub handle 31 (see FIG. 4). That is, since the up-and-down direction of the cleaner body 2 is reversed, the slide member 81 slides to a position opposite to the conventional position as shown in FIG. Similarly to the case where the main handle 30 is held, it is arranged at the lower limit position. Thereby, even if it changes over from the main handle 30 to the sub handle 31, the flow path Z extended diagonally downward is formed. Therefore, since the exhaust from the exhaust port 14 is discharged obliquely downward toward the outside of the machine (see the thick line arrow), it does not affect the hand holding the sub handle 31 on the upper end side of the cleaner body 2. The user can grip the sub handle 31 comfortably.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.
