In addition, the vacuum cleaner main body can be routed through the suction hose to perform a wide range of cleaning comfortably.

In this conventional example, since the main body of the vacuum cleaner is composed of a plurality of irregularly shaped parts, various storage methods have been conventionally proposed.

[0005] The most mainstream method at present is to store the entire body in a vertical position without disconnecting the connection. Specifically, first, stand the back part of the main body so as to be in contact with the floor surface, further remove the fixing of the extendable connecting pipe, shorten its length, and hold it in the vertical posture with the mouthpiece below and the handle at the top. To be installed on the bottom side of the vacuum cleaner body. In this mounting method, the protrusion provided at the end of the connection pipe on the suction body side is inserted into a recess provided at the tip of the vacuum cleaner main body.

[0006] The connecting pipe used in these conventional examples is composed of two pipes, an outer pipe and an inner pipe, and the outer pipe is provided with a locking recess formed along the longitudinal direction of the inner pipe. It is structured to be fixed at any position via a stopper.

This conventional example is disclosed, for example, in Japanese Patent Application Laid-Open No. 8-191.
No. 781 and JP-A-9-56648.

[0008]

According to the conventional vacuum cleaner, a plurality of components can be stored in a vertical position without being disassembled, so that they can be used immediately when desired and the installation property can be improved. .

However, there are the following problems.

(1) First, the operation of erecting the vacuum cleaner body must be performed in a crouching posture or a crouching posture. (It is not recommended to set up via a suction hose.) (2) The conventional connection pipe is made to be able to expand and contract by sliding two pipes of different diameters. You have to manipulate and adjust its length with both hands. In use, the length of the connecting pipe must be adjusted using both hands.

(3) Next, in the crouching posture or the crouching posture, the connection pipe must be attached to the bottom side of the vacuum cleaner main body by holding down the vacuum cleaner main body in the vertical posture.

(4) Transporting is prohibited in this vertical storage position, and the vacuum cleaner main body and the connecting pipe must be separated and disassembled and held in a bent position or bent position.

As described above, the conventional vacuum cleaner has to take a crouching posture or a crouching posture when storing or transporting, and the user is forced to take an unreasonable posture. By solving the problem, it is expected that the vacuum cleaner will be easier to use.

Next, a method of operating the vacuum cleaner 1 according to the present embodiment will be described in more detail with reference to FIGS. FIG. 11 is an operation explanatory diagram for changing from the cleaning posture to the storage posture.

In FIG. 2, in the vacuum cleaner 1 of this embodiment, the user can perform various operations by holding the handle 300 in a standing posture. For example, in this embodiment, the user holding the hand handle 300 moves the mouthpiece 500 by holding the handle portion 302 straight and moving the hand handle 300 in the V1 direction, so that the normal suction port 1004 can be cleaned in a wide range of directions. At this time, good traveling can be obtained via the large rear roller 1007 and the front roller 1006, which are mainly subjected to the load from the hand handle 300. Further, the main body 1 of the vacuum cleaner is connected via a suction hose 200 connected to the handle 300 at hand.
00 can be pulled and run.

Further, by twisting the handle portion 302 from the movement in the direction V1, the mouthpiece 500 is turned in accordance with the twist angle, so that the suction body 1000 is moved in an oblique posture, or the turned suction body is turned. Suction body 5 so as to turn the steering wheel of the car along the short direction of 1000
00 can be changed. At this time, the suction hose 200 is connected to the connection pipe 40 of the handle 300 at hand.
By rotating around the center axis A1 of 0, it always operates below the handle 300,
Even if the user twists the handle 302, the suction hose 20
Since 0 is not raised, the burden on the hands can be reduced. In addition, even when the hand-held handle 300 is suddenly moved even when the hand-held handle 300 is suddenly moved during the pulling operation of the vacuum cleaner main body 100, the hand-held handle 300 can have a buffering action, so that the burden on the hand can be reduced. it can.

Further, in this embodiment, the handle portion 302 is twisted by 90 degrees so that
Can be turned by about 90 degrees. And by making the longitudinal direction of the mouthpiece 500 the same direction as the front-back direction of the handle 300, the mouthpiece 500 can be inserted into a narrow gap, and the long side of the front part of the mouthpiece 500 is attached to the wall surface. The contact can be made to move in the V2 direction.

Referring to FIGS. 1 and 11, a method of storing the vacuum cleaner 1 will be described. Here, FIG. 11 is an explanatory diagram showing a process of changing the vacuum cleaner main body 100 from the cleaning posture to the vertical storage posture. First, FIG. 1A shows a landscape posture in which the main body 100 of the vacuum cleaner is supported by the moving means 102. A process of changing from this state to the vertical storage posture will be described. In order to change from the state shown in FIG. 3A to the vertical storage posture, the hand handle 300 or the hand handle 300 and the connection pipe 400 are held by hand to float the mouthpiece 500, and the first piece of the floated mouthpiece 500 is lifted. And the first fixing means 101 of the vacuum cleaner main body 100 are connected. At this time, since the suction body 500 includes the first rotating portion 1503 near the center of gravity G1 of the suction main body 1000, the bottom surface is in a state parallel to the cleaning surface (a state close to parallel). be able to. Therefore, the first fixing means 501, ie, the rear roller 100
7 can be directed to the user holding the handle 300 at hand. Moreover, since the rear roller 1007 is provided at the end of the projecting portion 1012 projecting rearward of the mouthpiece main body 1000, the user can see the first fixing means 101 as the first fixing means 101 while looking at the rear roller 1007. 101,
Positioning for connection of 501 is easy.

Here, in this embodiment, the mouthpiece 50
The first fixing means 10 is used to improve the handleability when lifting the cleaning surface once from the cleaning surface and landing the cleaning surface again on the cleaning surface.
In order to improve the handleability of the connection between 1,501, the bottom surface of the suction body 500 is configured to be parallel to the cleaning surface. However, it is not always necessary to take the parallel posture in order to improve the handleability of the connection between the first fixing means 101 and 501. For example, in the conventional mouthpiece 500, the front portion of the mouthpiece 500 is lowered when the mouthpiece 500 is lifted because the center of gravity G1 is located at the front. However, the front part of the mouthpiece 500 is lifted, and the rear roller 10 is lifted.
The center of gravity G1 of the suction main body 1000 may be provided on the rear side of the first rotating unit 1503 rather than the horizontal position so that 07 projects downward.

According to this embodiment, the user operates the first fixing means 101 by the operation shown in FIG.
501, the hand handle 300 is pushed down along the longitudinal direction of the connecting pipe 400 so that the tip (hose mounting portion side) of the vacuum cleaner main body 100 is moved around the rotation axis B1 of the large wheel 103. Rotate it in a floating state to change it to the state shown in the figure (b), and push it down further (c)
As shown in the figure, the back of the vacuum cleaner main body 100 (exhaust portion 154).
Side) can be made to take a vertical storage posture such that it contacts the cleaning surface.

In this embodiment, the rotating portion 130 as the first fixing means 101 is rotated by the pressing operation of the hand handle 300 to start the winding switch 127. The power cord 120 can be drawn into the cord reel device 123 based on the power cord. Thereby, the user can omit the operation process of the winding switch 127.

In this embodiment, the position of the center of gravity G1 of the main body 100 of the vacuum cleaner is moved backward by winding the power cord 120, and the first fixing means 101 rotates the large wheel 103. The vacuum cleaner main body 100 is provided near the axis B1, and the large wheel 103 is a wheel having a large diameter, and the pushing-down operation is pushed obliquely rearward from above the front part. Is a fixed position, and the posture can be changed lightly.

In the vertical storage position, the first
Fixing means 101 and 501 are connected. From this state, the trigger switch 3 provided on the handle 300
By operating 01, the fixing of the connection pipe 400 can be released. In this embodiment, the release state is maintained while the trigger switch 301 is pulled, and the trigger switch 301 is released to release the trigger switch 301 to a fixed state.
Therefore, when shortening the connection pipe 400, the trigger switch 301 is pulled. Thus, the user can easily handle the operation because the operation and the operation are performed in conjunction with each other.

Further, by performing an operation of further pushing down the hand handle 300, the length of the connection pipe 400 is reduced. That is, the end of the second tube 440 is taken into the first tube 420. Due to the continuation of the pushing-down operation, the vacuum cleaner main body 100 in which the mounting protrusion 410 as the second fixing means 401 provided at the lower end of the first pipe 420 is positioned at the top in the vertical storage posture. The second fixing means 108 is inserted into the mounting recess 109.

The mounting recess 109 is connected to the connection pipe 400.
Is a position where the mounting projections 410 are inevitably reached by being pushed straight down to the lower rear, and, when viewed from the user, the mounting projections 410 protrude greatly,
In addition, since the mounting recess 109 is provided at the upper end, the positional relationship between the mounting projection 410 and the mounting recess 409 can be seen, and the fitting is easy. Then, the length of the connection pipe 400 is fixed again by operating the trigger switch 301, so that the handle 300
Is fixed so as to be carried on the back of the vacuum cleaner main body 100. Thus, the vacuum cleaner 1 is supported by the pair of large wheels 103 and the mounting projections 410 provided on the upper rear surface of the vacuum cleaner main body 100, and the vertical storage posture having the handle 300 at the upper end thereof. It can be.

According to this vertical storage posture, the installation area can be reduced in the installation state, so that the vacuum cleaner 1 composed of a plurality of irregularly shaped parts can be assembled and used immediately without taking up space between furniture or a corner of a room. Can be stored in a state.
In this vertical storage position, a suction body assembly 600 including the handle 300, the connection pipe 400, and the suction body 500.
Are the first and second fixing means 501, 101, 108,
Since the vacuum cleaner 1 is fixedly supported by the vacuum cleaner main body 100, the vacuum cleaner 1 in the vertical storage posture can be lifted or moved via the hand handle 300 disposed at the upper end.

For example, in the case of cleaning, the user may move the vacuum cleaner 1 in the vertical storage position, which is arranged in the corner of the room, by holding the handle 300 and gently lifting it. The posture can be changed so that the large wheel 103 is turned to the right. And the hand handle 30
0, the vacuum cleaner main body 100 is supported by a pair of large wheels 103, the vertical storage posture is tilted, and the vacuum cleaner 1 can be easily rotated by two wheels by pulling through the hand handle 300 as it is. It can be moved by traveling.

That is, in the conventional vacuum cleaner 1, it is possible to take the vertical storage position, but the connection pipe 400 is maintained so that the connection pipe 400 maintains the vertical position with respect to the main body 100 of the vacuum cleaner. The connecting means 400 is separated from the vacuum cleaner 1 even if the handle 300 is pulled because the fixing means provided in the vacuum cleaner 1 only scratches the vacuum cleaner 1. For this reason, in the conventional example, when the vacuum cleaner 1 in the housed state is moved, it must be held by a handle provided on the vacuum cleaner main body 100, for example, the first retractable handle 136 or the like. Therefore, the user must change the state from the standing posture to the crouching posture, and hold the handle of the vacuum cleaner 1.

However, according to this embodiment, since the connecting pipe 400 is fixed to the main body 100 of the vacuum cleaner, the vacuum cleaner 1 can be connected via the handle 300 provided at the upper end of the connecting pipe 400. Can be moved. In addition, since the handle 300 is arranged at a high position, the user can move the electric vacuum cleaner 1 without greatly changing the posture from the standing posture.

When cleaning is performed at a predetermined position, the user operates the trigger switch 301 provided on the hand handle 300 to release the fixing of the connection tube 400, and pulls up the hand handle 300 as it is. The second
Can be disconnected. Then, the trigger switch 301 is opened in a state where the handle 300 is further pulled up and the length of the connection pipe 400 is set to an arbitrary length, thereby fixing the length of the connection pipe 400 again. By raising
By rotating the fixing means 501 and 101 around the rotation axis B1 of the large wheel 103, the vacuum cleaner main body 100 in the vertical storage posture can be changed to the horizontally long cleaning posture supported by the traveling means 102. . Since the connection of the first fixing means 501 and 101 is released by the operation for changing to the cleaning posture, the user can place the mouthpiece 500 on the cleaning surface. Then, the power cord 120
By pulling it out and plugging it into a household power outlet, cleaning can be started.

As described above, according to this embodiment, the user can operate most of the operations with the hand handle 300 arranged at a position where the user can operate in the standing posture. Since the operation of the vacuum cleaner can be performed without greatly changing the posture from the posture, it is possible to reduce the load of housework that places a burden on the lower back.

Of course, this embodiment is not limited to the above operation method. For example, the user takes the crouching posture, changes the vacuum cleaner main body 100 in the cleaning posture to the vertical storage posture, further raises the mounting bracket 105, pulls in the power cord 120, and pulls the mounting bracket 105 while pulling in. First fixing means 501, 1
The second fixing means 401 and 108 may be connected while operating the second lock switch 403 to adjust the length of the connection pipe 400. Similarly, the vacuum cleaner main body 100 in this vertical storage posture is
It is also possible for the user to change to the cleaning posture by directly operating the second lock switch 103 and the mounting bracket 105 in the crouching posture.

As described above, according to this embodiment, the user can select two operations. One is to directly operate the operation of the trigger switch 301 and the operation of the mounting bracket 105 by hand. The other is to operate indirectly via the hand handle 300. With these two operations, selection can be made according to the user's preference.

The structure is not limited to the structure of the first embodiment shown in FIG.

For example, when the trigger switch 301 is provided below the handle portion 302, the trigger switch 301 is operated with an index finger, so that the trigger switch 301 is pulled up with a structure as shown in FIGS. A simple structure allows easy operation.

That is, in the first embodiment shown in FIG.
1 is pulled up as shown by an arrow E1 so that the first connecting rod 3
83 is converted via the connecting plate 381 to form the second connecting rod 3
A stress is applied to push the end portion 84 downward as indicated by arrow E2.
The stress abuts on the end of the third connecting rod 426 of the connecting pipe 400 and pushes it downward due to the connection between the handle 300 and the connecting pipe 400. Then, the other end of the third connecting rod 426 rotates the fixing claw 428 to pull up the claw fixing the second tube 440 to release the fixed state.

In the embodiment shown in FIG. 11C, the direction of the force is not changed by the connecting plate 381 and the trigger switch 3 is turned on.

May be directly transmitted to the connecting pipe expansion / contraction mechanism 402 by the connecting rod 426). Specifically, the trigger switch 301 is formed in a rod shape, the center of which is rotatably attached to the switch hole 385, and one end is exposed to the outside.
The other end is located inside, and the first connecting rod 38
3 is installed. According to this structure, the number of parts can be reduced because the connecting plate 381 can be eliminated and the number of connecting rods can be reduced to two.

On the other hand, when the trigger switch 301 is provided above the handle portion 302, it is easy to apply a force by pressing with the thumb. When the trigger switch 301 is pressed in this manner, a converting means for converting the stress, for example, the connecting plate 381X is newly provided on one of the hand handle 300 and the connecting pipe 400. For example, in the structure as shown in FIG. 3B, by providing a connecting plate 381X at the handle connection portion 434 of the connection pipe 400, the force for pushing down the trigger switch 301 as shown by the arrow E3 is converted, and the claw portion is pulled up and fixed. It can be canceled.

As described above, in this embodiment, for example, the structure of each part in FIG. 12 is appropriately combined in consideration of the location where the trigger switch 301 is provided and the direction of the stress for operating the trigger switch.
