Description

[Detailed Description of the Invention] [Industrial Application Fields] Ordinary vacuum cleaners for home use have an oval or spherical body with wheels, and a floor suction device connected to the end of an extension pipe via a connecting hose. It is designed to be used by connecting tools, etc.

Then, while grasping the vicinity of the grip of the connected connection hose and pulling the main body, cleaning is performed by sliding the floor suction tool back and forth along the floor surface. This type of vacuum cleaner, which cleans by pulling, has a floor suction device attached to the end of an extension pipe connected to a connecting hose, so the cleaning radius is large despite the short distance the main body moves, and the accessories are not included. It has features such as being able to be stored compactly within the case.

In addition to pull-type vacuum cleaners, there are also stand-type vacuum cleaners that have an upright structure. A stand-type vacuum cleaner has a floor suction device integrally attached to the lower part of the main body, and the vacuum cleaner cleans by pushing and sliding the floor suction device together with the main body. Therefore, here, a vacuum cleaner that pulls the main body will be referred to as a "pull wheel type" and a vacuum cleaner that pushes the body will be referred to as a "push wheel type." The “push wheel-shaped” vacuum cleaner is
It has the advantage of being able to start cleaning the floor immediately, and of being able to store the entire vacuum cleaner in a stand up position in a narrow floor space.

The present invention relates to a vacuum cleaner, and particularly to an ordinary "pull wheel" type vacuum cleaner.
This invention relates to a vacuum cleaner that has been improved so that it can be used like a "push wheel" vacuum cleaner.

[Prior Art] FIGS. 6A and 6B are explanatory diagrams of the configuration of a conventional "pull wheel type" vacuum cleaner.

In Figures 6(A) and (B), (1) is the floor surface, (
2) is the main body of the vacuum cleaner. (3) is an operating section provided on the main body (2), (4) is an intake port, (5) and (6) are front wheels and rear wheels, and (7) is a cord. (8) is a connecting hose, (9) is a gripping part, (10) is a hand switch, (11)
) is the extension pipe, (12) is the floor suction device, and (13) is the case.

A conventional vacuum cleaner having such a configuration is used as follows.

Connect the hose (8) and extension pipe (
11) and the floor suction device (12) and turn on the hand switch (10), the electric blower inside the main body (2) is driven. Then, when the floor suction device (11) is placed on the floor surface (1) and slid, dirt and dust on the floor surface (1) is sucked in from the floor suction device (12) and the extension pipe (1) -1) and the connecting hose (8), the dust is collected into the main body (2).

After cleaning, remove the connecting hose (8), extension pipe (11), and floor suction device (12) from the main body (2) and place them in the case (13) as shown in Figure 6 (B). Place the main body (2) on top and store it.

[Problems to be Solved by the Invention] As described above, in the conventional vacuum cleaner, the connecting hose (8), the extension pipe (11), and the floor suction device (
12) to the main body (2). Furthermore, when cleaning is completed, accessories such as the connecting hose (8) are removed and placed in the case (13), which is then covered with the main body (2) and stored.

For this reason, accessories such as the connecting hose (8) must be connected to the main body (2) each time cleaning is performed, which requires time to prepare and extremely troublesome installation and removal operations.

Further, when cleaning is interrupted due to an unexpected guest, etc., the main body (2) of the vacuum cleaner with all accessories connected ends up being thrown onto the floor. For this reason, a long extension pipe (11
) etc. not only occupy a large area of the floor surface and become a nuisance, but also have the problem that there is a risk of injury due to contact with the extension pipe (11), connection hose (8), etc. and tripping.

The present invention was made with this in mind, and its purpose is to use it as an ordinary vacuum cleaner in the form of a "pulling wheel", and when necessary, use the fixing mechanism to attach the extension pipe to the main body in a stand state. To provide a vacuum cleaner that can be fixed to a vacuum cleaner and used in the same manner as a "push wheel" vacuum cleaner.

[Means for Solving the Problems] The present invention provides a fixing mechanism that removably fixes the main body and the extension pipe at a plurality of locations, and the extension pipe is tilted and fixed to the main body by this fixing mechanism, so that the extension pipe can be fixed to the main body in a stand state. This is a vacuum cleaner that can be held in place.

[Function] After cleaning the "puller type", leave the connecting hose, extension pipe, and floor suction device connected to the main body, and use the fixing mechanism to put the main body in a stand state and fix the extension pipes at multiple locations. . The main body and the extension pipe, which are fixed at multiple points by the fixing mechanism, are firmly connected to each other and held in a stand-up state similar to a "barrow-type" vacuum cleaner.

Also, if necessary, in the stand state with the main body and extension pipe connected, turn on the hand switch and grasp the grip to push out the main body. When the main body is pushed out, the suction surface of the floor suction device moves along the floor as a whole, and dirt on the floor is sucked into the main body, creating a "push wheel-shaped" vacuum cleaner. Cleaning is done in exactly the same way.

[Embodiment] Fig. 1 is an explanatory diagram of the configuration of an embodiment of the present invention, and Fig. 2 is an explanatory diagram of the rear side of the main body. In both figures, parts having the same functions as those in FIG. 6 are denoted by the same reference numerals, but will be explained in more detail here.

The operation of the vacuum cleaner of the present invention configured as described above will be explained next.

Fit the connection part of the connecting hose (8) into the intake port (4) of the main body (2), and connect the extension pipe (11) and the floor suction device (12>) as shown in Figure 1.The cord (7) ) plug A
When Cloo V is plugged into an outlet and the hand switch (10) is turned on, the electric blower built into the main body (2) of the vacuum cleaner is activated, and the air intake port (4) is opened inside the main body (2).
A ventilation path is formed in which air is sucked in from the side, passes through the dust collection chamber, and heads toward the dispersion exhaust port (16).

Now, hold the area near the grip part (9) and move the front and rear wheels (5).
While pulling the main body (2) into a "pulling wheel" shape by rolling and (6), place the floor suction tool (12) on the floor (1) and slide it back and forth as shown by the arrow. As a result, dirt and dust on the floor (1) are sucked in through the gap formed between the floor suction tool (12) and the floor (1). The sucked dust passes through the extension pipe (11) and connection hose (8) to the main body (
2) The dust is collected in the dust collection bag. In the exhaust air after dust collection, the minute components of the dust mixed in are captured by the internal filter, and the filtered clean air is discharged to the outside of the main body (2) from the dispersion exhaust port (23).

For example, if a buzzer sounds while cleaning to notify you of a visitor,
Operate the hand switch (10) to turn off the power. Lift the tip side of the main body (2) and rotate it using the left and right rear wheels (6) as fulcrums. Lift the tip side and attach the auxiliary wheel (24)
When the main body (2) comes into contact with the floor (1), the main body (2) is supported by the left and right rear wheels (6) and the auxiliary wheels (24) and becomes an upright stand state. ), and hold the engagement piece (34) in the fixing mechanism (30),
Insert into the mounting hole (32) on the main body (2) side. At the same time, remove the holder (33) located at the dotted line on the bottom of the main body (2).

The upper part of the extension pipe (11) is fixed with an engagement piece (34) and a mounting hole (32) that are fitted together with a loose tab;
The lower part thereof is held between the locking portions (34) of the holder (33). As a result, the main body (2) and the extension pipe (11
) are fixed and connected to each other at two points. Main body (2
) and the extension pipe (11) are shown in a fixed state in FIG. Inclination angle θ of the extension pipe (11) in a fixed state
is approximately 120 degrees, and the suction surface of the floor suction device (12) is in parallel contact with the floor surface (1). After doing this, I go around the entrance and greet the guests.

When the guests return and you want to resume cleaning after interruption, use the holder (
33) in the opposite direction of the arrow and return it to the position indicated by the broken line.

Next, the engagement piece (34) is pulled out from the mounting hole (32) to release the connection between the extension pipe (11) and the main body (2). When the connection is released and the user moves forward holding the extension pipe (11), the connection hose (8) will extend and the main body (2) will rotate counterclockwise around the rear wheel (B) and fall forward. As a result, the main body (2) is placed on the floor surface (1) with the front wheels (5) and rear wheels (6), and it is possible to perform "pulling wheel" type cleaning in the same way as in the front.

In addition, if necessary, when the main body (2) and the extension pipe (11) are connected in a stand state, turn on the hand switch (10) and squeeze the grip part (9) to push out the main body (2) and the extension pipe (11). 11) move forward as one. At the same time, the suction surface of the floor suction tool (12) moves along the floor (1), and dirt on the floor is sucked into the main body (2).

In this case, since the main body (2) and the extension pipe (11) are securely fixed at two places, the main body (2) can be moved by grasping the grip part (9>) even when the floor is covered with a carpet with high resistance. This allows for smooth cleaning.In this way,
Cleaning is similar to that of a “push wheel” vacuum cleaner.

After cleaning is completed, it can be stored in a stand position as shown in Figure 4, leaning against the corner of the room. When the vacuum cleaner is in the corner of the room, the accessories such as the extension pipe (11) are stored in the case (13) as in the case of FIG.

Then, as shown in the figure, the engaging piece (34) is inserted into the mounting hole (32), and the extension pipe (11) is fitted and locked into the locking part (34) of the holder (33). By locking the locking portion (34), the extension pipe (11>) is fixed to the main body (2) at two places.As a result, the extension pipe (11) with the floor suction device (12) attached to the tip is securely connected to the main body (2), and the main body can be placed in a stand position on a thick carpet floor etc. with high resistance to carry out "push wheel type" cleaning.

In addition, in the above-mentioned embodiment, a vacuum cleaner in which the floor suction device (12) is connected to the tip of the extension pipe (11) is illustrated and explained. You can connect attached suction tools such as round brushes and suction nozzles. Further, although the cleaner body (2) is shown as having a substantially oval shape, the body (2) may have a rectangular shape, a cylindrical shape, or the like. In addition, the exhaust port (22) of the main body (2), (2
3) is provided on the back side, but it may be provided at other positions such as the side surface, and the fixing mechanism (30) and other structures are not necessarily limited to those in the embodiment.

[Effects of the Invention] As described above, the present invention provides a fixing mechanism that removably fixes the main body and the extension pipe at a plurality of locations, and uses this fixing mechanism to tilt the extension pipe and fix it to the main body, so that the extension pipe is in a stand state. A vacuum cleaner is constructed by holding the vacuum cleaner. As a result,
The integration between the floor suction tool and the main body is further strengthened, and it is possible to carry out "push wheel-shaped" cleaning even on long flocked carpet floors. Of course, like a regular "puller-type" vacuum cleaner, you can widen the cleaning radius by moving the main body a short distance, and the accessories can be disassembled into the case for compact storage. Furthermore, by fixing the main body and the extension pipe with a fixing mechanism, it becomes a "push wheel" configuration, which allows you to store it as is and start cleaning immediately.

Therefore, according to the present invention, it is possible to provide a vacuum cleaner that has a simple structure, can be used both as a "pull wheel type" and a "push wheel type," is extremely convenient to handle, and is suitable for home use.
