A bend attached to a tip of the extension pipe, and the posture is 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. It is a handy type vacuum cleaner of Claim 1 or 2 characterized by the above-mentioned.

According to a fourth aspect of the present invention, the suction tool is provided on the outer surface of the shutter, the shutter opening the sub suction port in the inverted posture while closing the sub suction port in the basic posture. The handy type vacuum cleaner according to claim 3, further comprising: a roller.
The invention according to claim 5 is characterized in that the suction tool takes the basic posture while holding the one handle, and the suction tool takes the inverted posture while holding the other handle. The handy type vacuum cleaner according to claim 3 or 4.

  The invention according to claim 6 is a handy type electric vacuum cleaner comprising a vacuum cleaner body that can be held and operated by hand, an extension tube extending forward from the cleaner body, and a suction tool attached to a tip of the extension tube. The vacuum cleaner main body includes an electric blower, a dust collecting chamber provided in front of the electric blower, and a connecting member for connecting the extension pipe provided in front of the dust collecting chamber. And a handle that protrudes rearward from the center of the rear end surface of the main body portion and is curved to face the peripheral surface of the main body portion toward the front, at least about the center of the main body portion. A handy-type vacuum cleaner comprising a handle that can be rotated 180 ° to be displaced to a first position and a second position that is 180 ° apart from the first position.

  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. The main body includes a dust collection chamber provided in front of the electric blower and a connecting member for connecting an extension pipe provided in front of the dust collection chamber.

  The pair of handles are provided symmetrically so as to protrude outward at positions spaced 180 ° in the circumferential direction of the peripheral surface of the main body. That is, the pair of handles are disposed symmetrically with the main body portion 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.

In addition, for example, when the area to be cleaned on the floor is moved from a wide area to a narrow area (or vice versa), if the handle is changed from one handle to the other, it is gripped by the weight of the electric blower. The main body is quickly arranged below the handle. Thereby, the handle can be smoothly changed in a stable state.
As a result, usability can be improved.

  According to the second aspect of the present invention, the cleaner main body and the extension pipe connected to the connecting member of the cleaner main body extend in a straight line. For this reason, when the handle is changed from one handle to the other, the main body rotates downward by the weight of the electric blower around the connecting member (cleaner main body) and the extension pipe, and quickly moves below the other handle. To do. As a result, the handle can be smoothly changed 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 stored in the dust collection chamber after passing through the bend, the extension pipe, and the connecting member.

  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 one handle of the pair of handles, and the suction tool takes an inverted posture while holding the other handle.

Here, since the pair of handles are arranged symmetrically with the main body portion serving as the center of gravity interposed therebetween, these handles can be smoothly changed in a stable state. Therefore, if one handle is gripped, the suction tool smoothly assumes the basic posture, and if the other handle is gripped, the suction tool smoothly assumes the inverted posture, which is convenient.
According to the invention of claim 6, 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 the 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. The main body includes a dust collection chamber provided in front of the electric blower and a connecting member for connecting an extension pipe provided in front of the dust collection chamber.

  And the handle | steering-wheel which protrudes back from the center of the rear-end surface of a main-body part, and curves so that it may face the surrounding surface of a main-body part toward the front is provided. The handle can be rotated at least 180 ° around the center of the main body to be displaced into a first position and a second position that is 180 ° apart from the first position. 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), the handle is set to either the first position or the second position so that it can be easily cleaned. You can change the attitude of the vacuum cleaner.

In this case, regardless of whether the handle located at either the first position or the second position is gripped, the main body comes below the gripped handle by 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.
As a result, usability can be improved.

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 suction tool 4 is in an inverted posture.
The suction tool 4 can be switched between the basic posture shown in FIGS. 1 and 2 and the inverted posture shown in FIG. 3. When the suction tool 4 is in the basic posture, the main suction port 52 faces the floor V from above (see FIGS. 1 and 2), and when the suction tool 4 is in the inverted posture, the sub suction port 53 is on 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 sub suction port 53 (see FIG. 3).
Then, when one handle 20A located at the upper end of the cleaner body 2 in the state of FIG. 1 is gripped, the handle 20A is located at the upper end of the cleaner body 2, while the body portion is directly below the handle 20A. 5 is located, and the other handle 20B is located on the opposite side of the handle 20A (the lower surface side of the cleaner body 2) with the main body 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.

In this state, when the handle 20A 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. 2, the roller 55 of the shutter 54 comes into contact with the wall W. This opens the shutter 54.
In the state shown in FIG. 1, the handle 20B is lifted slightly by changing from the handle 20A to the handle 20B. Then, the main body 5 and the handle 20A above the handle 20B in FIG. 1 in the vacuum cleaner main body 2 are centered on the extension pipe 3, the connecting member 8 and the main body 5 extending in a straight line. 5 is rotated downward by the weight of the electric blower 6 around the central axis J of the motor 5. Strictly speaking, the portion other than the suction tool 4 in the vacuum cleaner 1 is twisted 180 ° downward about the central axis J. Thereby, the main-body part 5 and the handle | steering-wheel 20A move to the downward direction of the handle | steering-wheel 20B rapidly, as shown in FIG. Therefore, the handle 20A can be smoothly changed in a stable state from the handle 20B, and the usability is good. Also, at the same time as the main body 5 and the handle 20A move, the extension tube 3 rises a little while twisting according to the handle 20B being lifted slightly, and at this time, the rear end side of the suction tool 4 is lifted. The posture of the suction tool 4 changes to an inverted posture, and the shutter 54 opens. At this time, as shown in FIG. 3, the suction tool 4 in the inverted posture, the extension pipe 3, and the cleaner body 2 are arranged on the same vertical plane.

When the handle 20B is changed from the handle 20B to the handle 20A in this state, the main body 5 and the handle 20B rotate downward together with the extension tube 3 and the connecting member 8, and as shown in FIG. 1, below the handle 20A. Be placed. At the same time, the posture of the suction tool 4 returns from the inverted posture to the basic posture.
In this way, the suction tool 4 takes a basic posture while holding the handle 20A, and the suction tool 4 takes an inverted posture while holding the handle 20B (see FIG. 3). When the handle 20A is changed from the handle 20B to the handle 20B, the main body 5 and the handle 20A are positioned below the handle 20B (see FIG. 3), and when the handle 20B is changed from the handle 20A to the handle 20A, the main body 5 and the handle 20B are Located below.
<Cleaning with a vacuum cleaner>
As shown in FIG. 1, with the suction tool 4 in the basic posture and the shutter 54 closed, an electric plug (not shown) of an electric cord connected to the cleaner body 2 is connected to an outlet (not shown). Connect. And if the switch (not shown) provided in the cleaner main body 2 is turned ON, electric power will be supplied to the electric blower 6, and the electric blower 6 will generate | occur | produce a suction force. This suction force acts inside each of the dust collection chamber 7, the connecting member 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, when the main suction port 52 is opposed to the floor surface V and the upper handle 20A is gripped and the suction tool 4 is moved on the floor surface V, dust on the floor surface V is collected by the main suction port 52. The air is sucked into the housing 50 from the main suction port 52 on the air sucked into the housing 50. Thereafter, these dust and air that have flowed into the housing 50 flow into the connecting member 8 of the cleaner body 2 through the bend 51 and the extension pipe 3.

  The dust and air that have flowed into the connecting member 8 flow into the dust collecting chamber 7 after passing through the connecting member 8. A disposable paper pack 60 (see also FIG. 4 described later) is accommodated in the dust collection chamber 7, and dust and air that have flowed into the dust collection chamber 7 enter the paper pack 60. And while dust cannot pass through the paper pack 60 and accumulates in the paper pack 60, air passes through the paper pack 60 and is then discharged from the exhaust port 14 to the outside of the cleaner body 2 (outside the machine). .

  In the vacuum cleaner main body 2, an extraction port 61 communicating with the dust collection chamber 7 is formed at a portion corresponding to the dust collection chamber 7 on the circumferential surface 5 </ b> A of the main unit 5. The lid 62 is opened and closed. By opening the lid 62, the paper pack 60 in the dust collection chamber 7 can be taken out, so that the dust accumulated in the paper pack 60 (in other words, the dust collection chamber 7) can be discarded.

  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. Therefore, dust can be effectively flowed into the housing 50 from the main suction port 52 and stored in the paper pack 60 of the dust collection chamber 7.

  On the other hand, as shown in FIG. 2, 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 (not shown) scavenge the dust on the wall W into the sub suction port 53, so that the dust adhering to the wall W is efficiently contained in the housing 50. Sucked into.

The dust sucked into the housing 50 is stored in the paper pack 60 of the dust collection chamber 7 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 paper pack 60.
With the suction tool 4 pressed against the wall W in this manner and the shutter 54 opened, the handle 20A 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 sideways, 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 7. 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 2), when the handle 20A is changed from the handle 20A to the handle 20B as described above, the suction tool 4 is in the 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 2), the auxiliary suction port 53 side becomes the bottom surface and the bend 51 side becomes the top surface. Thus, the housing 50 is thinned in the lateral direction (horizontal direction) (see also FIG. 8 described later). That is, 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.
The dust in the narrow area sucked into the housing 50 from the sub suction port 53 is stored in the paper pack 60 of the dust collection chamber 7 as described 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 2). On the other hand, in the inverted posture, the suction tool 4 can be thinned in the lateral direction. 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. 3). 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, since the handle 20A and the handle 20B are arranged symmetrically with the main body 5 serving as the center of gravity interposed therebetween, the handle 20A is held below the gripped handle 20 by the weight of the electric blower 6 regardless of which handle 20 is gripped. The main body 5 comes (see FIGS. 1 to 3). Thereby, since the center of gravity of the cleaner body 2 is located below the hand holding the handle 20, the cleaner body 2 can be moved in a stable state. Further, since the handle 20A and the handle 20B are arranged symmetrically and have the same shape, both the handles 20 can be gripped in the same manner and are easy to use.

  Further, 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 handle 20A and the handle 20B is changed from one to the other, the electric blower 6 Due to its own weight, the main body 5 is quickly placed below the gripped handle. In particular, since the cleaner body 2 and the extension pipe 3 extend in a straight line, when the handle 20 is changed from one handle 20 to the other handle 20, the connecting member 8 (the cleaner body 2) and the extension pipe 3 are used as axes. The main body 5 is rotated downward by its own weight of the electric blower 6, and quickly moves to the lower side of the other handle 20. Thereby, the handle 20 can be smoothly changed in a stable state, and the usability is good.

Since the handle 20 can be smoothly changed in a stable state as described above, if the handle 20A is gripped, the suction tool 4 smoothly assumes the basic posture (see FIGS. 1 and 2), and if the handle 20B is gripped. The suction tool 4 is in an inverted posture smoothly (see FIG. 3).
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.

Below, a modification is demonstrated.
<First Modification>
FIG. 4 is a side view of the cleaner body 2 according to the first modification. FIG. 5 is a side view of the cleaner body 2 of FIG. 4 in the maintenance state. Note that members similar to those described in the above-described embodiments are denoted by the same reference numerals, and description thereof is omitted (the same applies to the following modifications).

  In the case of the cleaner body 2 according to the first modification shown in FIGS. 4 and 5, the cleaner 1 can be stored in a compact manner. In the cleaner body 2 according to this modification, each of the rear side surface (lower side surface in FIG. 4) 23 of the handle 20A and the rear side surface (lower side surface in FIG. 4) 24 of the handle 20B is a flat surface. This is flush with the rear end face 5C. Both the rear side surface 23 and the rear side surface 24 form the rear side surface of the cleaner body 2 together with the rear end surface 5C, and project outward from the rear end surface 5C of the main body portion 5 in the radial direction in the radial direction of the main body portion 5. . That is, the vacuum cleaner body 2 includes a rear side surface 23 that forms one projecting surface projecting outward from the rear end surface 5C of the main body 5 by the rear end of the handle 20A, and a rear end surface 5C of the main body 5 by the rear end of the handle 20B. And a rear side surface 24 that forms the other overhanging surface.

Here, since the handle 20A and the handle 20B are provided symmetrically with respect to the central axis J of the main body 5, the rear side surface 24 of the handle 20B protrudes in a direction separated from the rear side 23 of the handle 20A by 180 °. ing.
Since the rear side surface 23 of the handle 20A, the rear side surface 24 of the handle 20B, and the rear end surface 5C of the main body 5 are flush with each other, the rear side surface 23, the rear side surface 24, and the rear end surface 5C are flush with each other. The flat surface 35 is formed in a unified state.

Further, as shown in FIG. 1, in relation to the storage of the vacuum cleaner 1, 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. A hook 59 is provided. The locking hook 59 may be provided on the suction tool 4. Although not shown, the cleaner body 2 is provided with a concave hook receiver for hooking the locking hook 59.
As described above, when the release button 9 of the connecting member 8 is pressed, the extension pipe 3 is unlocked from the cleaner body 2, so that the suction tool 4 and the extension pipe 3 (see FIG. 1) in an integrated state. ) 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 that has been located at the rear end of the cleaner body 2 until now is opposed to the floor (floor surface V) from above, and FIG. As shown in FIG. 2, the cleaner body 2 is erected so as to be vertically long. 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. Specifically, since the flat surface 35 is long and flat along the arrangement direction of the handle 20A, the main body 5 and the handle 20B, the vacuum cleaner main body 2 is placed on the floor so that the flat surface 35 faces the floor (floor surface V). Even if it mounts, the cleaner body 2 can maintain a stable posture without falling down in the arrangement direction.

  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 59 (see FIG. 1) of the extension pipe 3 is attached to the hook receiver ( (Not shown). 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 fixing the extension pipe 3 and the suction tool 4 to the vacuum cleaner main body 2 that is erected vertically and vertically, the vacuum cleaner 1 can be stored in a compact manner, which is convenient.

In the vacuum cleaner main body 2 according to this modified example, as shown in FIG. 5, the front end surface 5B of the main body 5, the vicinity of the front end surface 5 B on the circumferential surface 5 A, and the connecting member 8 include a lid 65. And can be separated from the cleaner body 2 with the paper pack 60. Therefore, by separating the lid 65 from the cleaner body 2, the paper pack 60 can be removed from the cleaner body 2, whereby dust collected in the paper pack 60 can be discarded.
<Second Modification>
FIG. 6 is a right side view of the cleaner 1 to which the cleaner body 2 according to the second modification is applied. FIG. 7 shows a state where the handle 67 is in the second position in FIG. FIG. 8 shows a state in which the suction tool 4 is rotated by approximately 90 ° in the horizontal plane in FIG.

  In the second modified example shown in FIGS. 6 to 8, the cleaner body 2 is provided with one rotatable handle 67 instead of the pair of handles 20 described above (see FIG. 1). Moreover, below, the front-back, left-right direction of the cleaner 1 which concerns on a 2nd modification is prescribed | regulated on the basis of the attitude | position of the cleaner 1 in FIG. In FIG. 6, the left side is the front side, the right side is the rear side, the back side is the left side, and the near side is the right side. Moreover, the left-right direction is synonymous with the width direction.

  Here, the vacuum cleaner main body 2 according to this modification includes a main body portion 68 having a hollow substantially cylindrical shape. The main body 68 includes the above-described electric blower 6 and the dust collection chamber 7 provided in front of the electric blower 6 therein. A connecting member 8 for connecting the extension pipe 3 provided in front of the dust collection chamber 7 is integrally provided at the front end of the main body 68. In such a vacuum cleaner main body 2, the main body 68 including the electric blower 6 which is a heavy object is the center of gravity.

The main body 68 includes a circumferential surface 68A having a central axis K extending downward in FIG. 6, a front end surface 68B that blocks the circumferential surface 68A from the front side, and a rear end surface 68C that blocks the circumferential surface 68A from the rear side. Is integrated.
In the upper portion of the circumferential surface 68A, a bulging portion 69 that bulges so as to protrude one step upward is integrally provided in the front region thereof. The exhaust port 14 described above is formed in the rear part of the left and right regions of the circumferential surface 68A in a state where a plurality of slits are vertically arranged in the front and rear direction and are arranged in the vertical direction. The connecting member 8 described above is connected to the front end face 68B. The rear end face 68C is substantially circular and is flat along a direction orthogonal to the central axis K. The central axis K passes through the circular center position of the rear end face 68C and the connecting member 8, and the extension pipe 3 described above is positioned on the central axis K.

One end of an electric cord 70 for supplying electric power to the electric blower 6 is connected to the cleaner body 2. When an electric plug (not shown) attached to the other end of the electric cord 70 is connected to an outlet (not shown) and a switch (not shown) provided in the cleaner body 2 is turned ON, the electric blower 6 Is supplied with power.
The handle 67 protrudes rearward along the central axis K from the center of the rear end surface 68C of the main body 68 (position through which the central axis K passes), and then bends outward in the radial direction of the main body 68. It curves and extends forward. In FIG. 6, the front end of the handle 67 is opposed to the bulging portion 69 from the rear side with a gap, and the front portion of the handle 67 (the outer portion in the radial direction of the main body portion 68) is the main body portion 68. Is opposed to the circumferential surface 68 </ b> A with a gap in the radial direction of the main body 68.

  In the handle 67, a base end portion 67 </ b> A connected to the rear end surface 68 </ b> C of the main body portion 68 has a columnar shape with the central axis K as a circle center and is rotatably supported by the main body portion 68. Therefore, the handle 67 can be rotated around the central axis K. Therefore, the handle 67 rotates at least 180 degrees around the center (center axis K) of the main body portion 68, and faces the bulging portion 69 from the rear side (see FIG. 6), and the first position. It can be displaced to a second position (see FIGS. 7 and 8) that is 180 ° apart from the position.

The main body 68 is provided with a lock mechanism 71 for locking the handle 67 at each of the first position and the second position.
9A is a front sectional view of the handle 67 and the locking mechanism 71 in a state in which the handle 67 is locked, and FIG. 9B is a sectional view taken along the line AA in FIG. 9A. . FIG. 9C is a front sectional view of the handle 67 and the lock mechanism 71 in a state in which the handle 67 is unlocked, and FIG. 9D is a sectional view taken along the line BB in FIG. 9C. It is.

  In relation to the lock mechanism 71, as shown in FIG. 9A and FIG. 9B, the outer peripheral surface of the base end portion 67A of the handle 67 is provided with recesses 72 at two locations spaced 180 ° in the circumferential direction. Is formed. Also, as shown in FIG. 9B, an annular groove 73 is formed on the outer peripheral surface of the base end portion 67A on the rear side of the recess 72 (right side in FIG. 9B). The portion 67A is reduced in diameter at the portion where the groove 73 is formed.

In addition, the rear wall 74 that defines the rear end face 68C in the main body 68 is plate-shaped. In the rear wall 74, a round first through hole 74A is formed at a position where the central axis K passes, and at a position slightly away from the first through hole 74A in the radial direction of the main body portion 68, the second through hole 74A is formed. One through hole 74B is formed.
A portion where the groove 73 is formed in the base end portion 67A of the handle 67 is fitted into the first through hole 74A. As a result, the handle 67 is rotatably supported by the rear wall 74 of the main body 68 at the portion where the groove 73 is formed at the base end 67A. In this state, the portion that borders the first through hole 74A in the rear wall 74 is located between the portions that divide the groove 73 from the front and rear in the base end portion 67A, so that the handle 67 is detached from the rear wall 74. There is no. In this state, the front end portion of the base end portion 67 </ b> A is disposed inside the main body portion 68.

The lock mechanism 71 includes a lock member 75, a holder 76, and a release button 77.
The lock member 75 has an elongated cylindrical shape along the radial direction of the base end portion 67 </ b> A of the handle 67. In the lock member 75, one end on the base end portion 67A side forms a rounded tip 75A to close the inside of the lock member 75 from one end side, and the other end opposite to the one end communicates with the inside. An opening 75B is formed. A protrusion 75 </ b> C that protrudes radially outward of the lock member 75 is provided at one place on the outer peripheral surface of the lock member 75. An inclined surface 75D is formed at the end of the protrusion 75C that is farthest from the outer peripheral surface of the lock member 75. The inclined surface 75D is inclined inward in the radial direction of the lock member 75 and toward the tip 75A.

The holder 76 has a base portion 76A that protrudes frontward from the front side surface of the rear wall 74 of the main body portion 68 (the surface facing the inside of the main body portion 68 from the rear side), and a front end portion of the base end portion 67A of the handle 67 at the base portion 76A. It integrally includes a shaft portion 76B formed on the opposite side surface. The shaft portion 76 </ b> B has an elongated cylindrical shape extending toward the base end portion 67 </ b> A of the handle 67.
The release button 77 has a substantially cylindrical shape extending in the front-rear direction, and is fitted into the second through hole 74 </ b> B of the rear wall 74 of the main body 68 from the front side. The rear end portion of the release button 77 is rounded so as to bulge to the rear side in an arc shape, and is exposed to the rear outer side of the rear wall 74 from the second through hole 74B. A flange portion 77 </ b> A is integrally provided at the front edge of the release button 77 and extends in a hook shape outward in the radial direction of the release button 77. The flange 77A is engaged from the front side with a portion of the rear wall 74 that borders the second through hole 74B, so that the release button 77 is prevented from being released from the second through hole 74B of the rear wall 74 to the rear side. .

The release button 77 is integrally provided with a protrusion 77B. The protrusion 77 </ b> B is a long and narrow bar extending forward, and is disposed inside the release button 77. The front end portion of the protrusion 77B protrudes more forward than the flange portion 77A. An inclined surface 77C is formed at the front end of the protrusion 77B so as to be inclined with respect to the direction in which the protrusion 77B extends.
In the lock mechanism 71, the shaft portion 76B of the holder 76 is inserted into the opening 75B of the lock member 75, whereby the lock member 75 is slidably supported by the shaft portion 76B. Here, the coil spring 78 is externally fitted to the shaft portion 76 </ b> B and is partially disposed inside the lock member 75. A coil spring 78 is also included in the lock mechanism 71. The coil spring 78 is a compression spring and is compressed between the inner surface of the lock member 75 and the base portion 76A of the holder 76, thereby urging the lock member 75 in a direction away from the base portion 76A. Yes. The front end portion of the base end portion 67A of the handle 67 is located ahead of the lock member 75 in the direction away from the base portion 76A. As described above, the holder 76 holds the lock member 75.

In the lock member 75 held by the holder 76, the protrusion 75C faces the protrusion 77B of the release button 77 from the front side. At this time, the inclined surface 75D of the protrusion 75C and the inclined surface 77C of the protrusion 77B are in surface contact with each other in a parallel state.
9A, when the distal end 75A of the lock member 75 is fitted in any one of the recesses 72 on the outer peripheral surface of the base end portion 67A of the handle 67, the handle 67 cannot rotate. When the handle 67 is in the first position (see FIG. 6) as shown in FIG. 9A, the lock mechanism 71 locks the handle 67 in the first position.

  In this state, as shown in FIG. 9D, when the release button 77 is pressed from the rear side, the inclined surface 77C of the protrusion 77B of the release button 77 presses the inclined surface 75D of the protrusion 75C of the lock member 75 from the rear side. To do. Thereby, the force by which the inclined surface 77C presses the inclined surface 75D acts on the lock member 75 toward the base portion 76A of the holder 76. Therefore, the entire lock member 75 slides toward the base 76A against the urging force of the coil spring 78, and the tip 75A of the lock member 75 comes off from the recessed portion 72 that has been fitted so far. In this state, the handle 67 can freely rotate.

  Therefore, when the handle 67 that has been in the first position is rotated 180 °, the handle 67 is disposed in the second position (see FIG. 7). At this time, a recess 72 different from the recess 72 fitted so far is located at the tip of the tip 75A of the lock member 75. In this state, when the release button 77 is released after the handle 67 is arranged at the second position (releases the pressure), the inclined surface 77C of the protrusion 77B of the release button 77 becomes as shown in FIG. The inclined surface 75D of the protrusion 75C of the lock member 75 is not pressed from the rear side. As a result, the entire lock member 75 is separated from the base portion 76A by the urging force of the coil spring 78 and slides toward the base end portion 67A side of the handle 67. As shown in FIGS. 9A and 9B, the lock member 75 The tip 75A of the member 75 fits into a recess 72 different from the recess 72 that has been fitted so far. Therefore, the lock mechanism 71 locks the handle 67 at the second position, and the handle 67 cannot be rotated.

Thus, the lock mechanism 71 can lock the handle 67 at each of the first position and the second position, and can release the lock.
As shown in FIG. 6, when the handle 67 is in the first position, the suction tool 4 is in the basic posture. In this state, by grasping the handle 67 at the first position and moving the cleaner body 2 in a suspended state, the entire cleaner 1 can be moved to clean a wide area of the floor surface V.

  When the release button 77 of the lock mechanism 71 is pushed while the handle 67 is held, the handle 67 is unlocked. In this state, without rotating the handle 67, the portion other than the handle 67 and the extension pipe 3 in the cleaner body 2 are slightly floated while being rotated about 180 ° around the central axis K of the main body 68. . Then, as shown in FIG. 7, the handle 67 is rotated relative to the cleaner body 2 and is disposed at the second position, and the suction tool 4 is in an inverted posture. Thereby, the narrow area | region of the floor surface V mentioned above can be cleaned.

  In FIG. 6, after the handle 67 is unlocked, only the handle 67 is rotated and arranged at the second position. Then, since the handle 67 in the second position is disposed on the lower surface of the cleaner body 2, the cleaner body 2 and the extension pipe 3 are disposed so that the handle 67 is disposed on the upper surface of the cleaner body 2. A little floating while rotating about 180 ° around the central axis K. This also causes the suction tool 4 to be in an inverted posture as shown in FIG.

Then, when the handle 67 at the second position is rotated to the first position, the suction tool 4 can be returned to the basic posture as shown in FIG.
According to the second modification, when the area to be cleaned on the floor surface V is moved from a wide area to a narrow area (or vice versa), the handle 67 is moved to either the first position or the second position. By doing so, the attitude | position (strictly the attitude | position of the suction tool 4) of the cleaner 1 can be changed so that it may be easy to clean (refer FIGS. 6-8).

In this case, regardless of whether the handle 67 positioned at the first position or the second position is gripped, the main body 68 comes below the gripped handle 67 due to the weight of the electric blower 6. Thereby, since the center of gravity of the cleaner body 2 is located below the hand holding the handle 67, the cleaner body 2 can be moved in a stable state.
Therefore, usability can be improved. In addition, the handle 67 is located at the upper end side of the cleaner body 2 and floats from the floor surface V in the gripped state regardless of whether the handle 67 is in the first position or the second position. Can be prevented from hitting the floor surface V and damaging the floor surface V.
<Third Modification>

FIG. 11A is a perspective view of the slide member 81 of the exhaust adjustment mechanism 80, and FIG. 11B is a cross-sectional view of the slide member 81. 12A is a perspective view of the holding member 82 of the exhaust adjustment mechanism 80, and FIG. 12B is a cross-sectional view of the holding member 82.

In the third modification, when the exhaust port 14 described above is formed in the rear end surface 5C of the cleaner body 2 (see FIG. 1), the exhaust adjustment mechanism 80 shown in FIG. 10 is attached to the rear end surface 5C. ing. 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. 11 and a holding member 82 shown in FIG.

Referring to FIG. 11, the slide member 81 has a plate shape that is long in the direction in which the handle 20A and the handle 20B (see FIG. 1) are arranged on the rear end surface 5C. Note that the slide member 81 in FIG. 11 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. 11). In FIG. 11, four triangular protrusions 85 are formed in the slide member 81.

Referring to FIG. 12, 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 the triangular projections 85 (see FIG. 11) 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. 12A), 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. 10, in exhaust adjustment mechanism 80 in the completed state, slide member 81 is attached to holding member 82 from the side where holding groove 82 is formed in holding member 82. 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. 11A) in the direction orthogonal to the longitudinal direction thereof The other end 81B (see FIG. 11A) 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. 1) of the main body 5 of the cleaner body 2 from the rear side so as to close the exhaust port 14. 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. 13 is a cross-sectional view of the exhaust adjustment mechanism 80 when the handle 20A is gripped. FIG. 14 is a cross-sectional view of the exhaust adjustment mechanism 80 when the handle 20B is gripped.

  When gripping the handle 20A (see FIGS. 1 and 2), as shown in FIG. 13, the exhaust adjustment mechanism 80 is in a vertically long posture, and the slide member 81 is positioned at the lower limit by its own weight. It is in. 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 handle 20A on the upper end side of the cleaner body 2, the user can comfortably hold the handle 20A (see FIGS. 1 and 2).
On the other hand, when the handle 20A is replaced with the handle 20B, as described above, the handle 20A is positioned below the handle 20B (see FIG. 3). That is, since the upper and lower directions of the vacuum cleaner body 2 are reversed, the slide member 81 slides to a position opposite to the conventional one as shown in FIG. As in the case of holding the handle 20A, it is arranged at the lower limit position. Thereby, even if the handle 20A is replaced with the handle 20B, the flow path Z extending obliquely 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 take place on the hand holding the handle 20B on the upper end side of the cleaner body 2, so that the user Can comfortably grip the handle 20B.
<Fourth Modification>
FIG. 15 is a right sectional view of the cleaner body 2 according to the fourth modification.

As shown in FIG. 15, in the cleaner body 2 according to the fourth modified example, a portion of one of the handles 20 (here, the lower handle 20 </ b> B) that is farthest from the circumferential surface 5 </ b> A of the main body 5. The plate-like rib 90 is integrally provided so as to protrude forward and backward from the handle 20B.
In this case, the electric cord 91 connected to the cleaner body 2 and supplying power to the electric blower 6 can be wound around the handle 20B and stored. In a state where the electric cord 91 is wound around the handle 20B, the rib 90 is engaged with the electric cord 91, so that the electric cord 91 is prevented from falling off the handle 20.

As described above, the handle 20B can be used not only as a handle for gripping but also as a device for winding the electric cord 91, which is convenient.
The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.
