Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vacuum cleaner, and more particularly to a so-called stick-type vacuum cleaner.

[Conventional technology]

A conventional stick-type vacuum cleaner has a structure in which an extension tube is attached to a small vacuum cleaner body, and a suction port is attached to the tip of the extension tube.

[Problem that the invention seeks to solve]

However, with this type of structure, although it is suitable for cleaning the floor and low places close to it, the tip is too long for cleaning places much higher than the floor, such as walls and table tops.
It is not suitable as it is too heavy.

On the other hand, rechargeable vacuum cleaners are suitable for cleaning walls, tables, etc., but due to their size, weight, and other aspects of operability,
Since a rechargeable battery with a large capacity cannot be used, only a low-input and small-output vacuum cleaner can be obtained, and it is not suitable for cleaning large areas such as floors.

Therefore, as a vacuum cleaner that has the functions of both a stick-type vacuum cleaner and a rechargeable vacuum cleaner, we have developed a hand-held vacuum cleaner body that has a suction port on one side and has an electric blower and a rechargeable battery inside. and a mounting part for removably attaching the vacuum cleaner body, an extension pipe communicating with the suction port of the vacuum cleaner body is connected to one end of the mounting part, and a handle is attached to the other end of the fitting part. A vacuum cleaner has been proposed, which is equipped with a support member having a suction port connected to the tip of the extension tube, and in which the electric blower can be operated on either an AC power source or a DC power source by switching. No. 59-197554).

However, in such vacuum cleaners, the main body of the vacuum cleaner is detachably attached to and removed from the attachment part of the support, so for example, when the vacuum cleaner is not in use, the electric cord can be connected around the main body of the vacuum cleaner and the support. If a winding structure is adopted, even when only the vacuum cleaner body is used, the electric cord must be untied even though the vacuum cleaner body is powered by a rechargeable battery. , since it is a walking stick type,
Depending on the setting position of the protrusion as a wrapping part for wrapping an electric cord, there is a problem that the protrusion may get caught on clothing during operation.

The present invention has been made to solve these problems, and is a stick-type vacuum cleaner comprising the above-described handy type vacuum cleaner body and a support body to which the vacuum cleaner body is removably fitted. In a vacuum cleaner, the purpose is to prevent the electrical cord of the support from becoming an obstacle when attaching and detaching the vacuum cleaner body, or to prevent the wrapped part of the electrical cord from getting caught on clothing during operation. It is.

[Means for solving problems]

The present invention has a handy type vacuum cleaner main body that has a suction port on one side and an electric blower inside, and a mounting part to which the vacuum cleaner main body is detachably attached, and one end of the mounting part has the above-mentioned cleaning device. An extension tube is connected to the suction port of the vacuum cleaner body, a handle is attached to the other end of the fitting part, and a support body is connected to the suction port body at the tip of the extension tube, A rechargeable battery is provided which is charged by an alternating current VLN source relayed through the support, and the electric blower mode is changed to an alternating current type by switching between the direct current power source and the alternating current power source. l! It can be operated with either a DC power source or a DC power source.
The present invention is characterized in that a wrapping portion for an electric cord provided on the support and for supplying AC power is provided on a surface different from the mounting portion of the support.

[Effect]

According to the present invention, when the vacuum cleaner is not in use, the electric cord of the support body is wound around a wrapping part formed on a surface of the support body that is different from the attachment part of the vacuum cleaner main body, and the When cleaning using only the main body, the cord wrapped around the main body should not become an obstacle when attaching and detaching the main body of the vacuum cleaner.

A (+) side charging terminal 79 is connected to an intermediate position of the next coil.

Next, the operation of the vacuum cleaner of this embodiment will be explained.

When using this vacuum cleaner to clean low places such as floors, the vacuum cleaner main body 1 is fitted and attached to the attachment portion 32 of the support 31 before use.

When the vacuum cleaner main body 1 is attached to the mounting part 32, the vacuum cleaner main body 1
each pair of AC terminals 55 of the internal circuit section 51 provided therein;
A pair of DC terminals 59 are respectively connected to a pair of DC power terminals 74 and a pair of charging terminals 79 of the in-support circuit section 5λ provided on the support 31, so that the AC circuit 53 and the AC power circuit 72 are connected to each other. In addition to connecting, the DC power supply circuit 5
4 and the charging circuit 73 are connected.

Also, by attaching the vacuum cleaner main body 1 to the attachment part 32, the second switch button 19 is pressed and the second changeover switch 6 is pressed.
2 is turned off and the DC'rtm circuit 54 is opened.

Therefore, even if the first selector switch 56 is turned to the DC power supply circuit 54 side, the electric blower 12 will not operate. On the other hand, the first changeover switch 56 is turned on to the AC circuit 53 side, and the AC power supply 71
When the electric blower 2 is turned on, the electric blower 2 is activated, so cleaning is performed in this state.

By the way, when the vacuum cleaner main body 1 is fitted into the mounting portion 32, the charging circuit 73 and the rechargeable battery 61 of the DC power supply circuit 54 are connected, so that the rechargeable battery 61 is charged.

This charging is carried out between the AC N source circuit 72 and the AC circuit 53.
Charging is performed even while the electric blower I12 is being operated with alternating current from the charging station, so charging efficiency is good.

Next, when cleaning a slightly higher place such as the top of a table, the extension tube 33 of the support body 31 is too long and cleaning is difficult, so the vacuum cleaner main body 1 is removed from the attachment part 32 of the support body 31. Support 3
When the vacuum cleaner main body 1 is removed from the first mounting portion 32, the second switch button 19 protrudes and the second changeover switch 62 is turned on, making it possible to use the rechargeable battery 61 as a DC power source. When the changeover switch 56 is turned on to the DC power supply circuit 54 side, the electric blower 2 is operated by the rechargeable battery 61, so cleaning is performed in this state. In this case, the nozzle 23 is removed from the nozzle storage recess 24 and inserted into the suction port 21.

By the way, the electric circuit of the vacuum cleaner consists of an in-body circuit section 51 on the side of the vacuum cleaner body 1 and an in-support circuit section 52 in the support body 31.
Since there is no charging transformer 75 or the like inside the vacuum cleaner body 1, the weight of the interior of the vacuum cleaner body 1 is reduced, the cleaning body 1 is easy to hold, and cleaning is facilitated.

Furthermore, when the cleaning main body 1 is attached to the support 31 for cleaning, the nozzle 23 is fitted into the nozzle storage recess 24, so there is no chance of the nozzle 23 being lost. When cleaning only with the cleaner body 1, the nozzle 23 can be removed from the storage recess 24 and immediately attached to the suction port 21, eliminating the need for bringing the nozzle 23 from another storage location.

In addition, when the vacuum cleaner is not in use, the electric cord 44 is wound around the first and second hooks 39 and 40 and stored, and the vacuum cleaner body 1 is fitted onto the mounting portion 32 of the support 31 and attached to the wall of the room. 4
The hook hole 41a is engaged with the third hook 42 provided in the vacuum cleaner body 1, and the vacuum cleaner, which is integrated with the support body 31 and the vacuum cleaner body 1, is hung.

. In this way, the vacuum cleaner can be hung on the wall surface 43, etc., so a large space is not required for the vacuum cleaner, and the vacuum cleaner can be used easily. The hook hole 41a, which is engaged with the third hook 42, is provided on the back surface of the mounting portion 32 of the support body 31 so as to be located inside the wound electric cord 44, so that the vacuum cleaner can It will be supported by the most important parts such as the vacuum cleaner body 1 and the electric cord 44,
The vacuum cleaner is hung stably.

Also, the hook 39°40 is the part where the electric cord 44 is wrapped.
Since the hook hole 41a is provided on the back side of the attachment part 32 of the support body 31, the electric cord 44 is located on the wall surface 43 side when the vacuum cleaner is hung, so the appearance is good. Further, since the mounting portion 32 is located on the outside surface side, when cleaning using only the vacuum cleaner body 1, the vacuum cleaner body 1 can be attached and detached while the support body 31 is hung on the wall surface 43. .

Further, by running a vacuum cleaner while the electric cord 44 is plugged into an outlet, the rechargeable battery 61 can be charged in this state.

When the electric cord 44 that has been wound and stored around the first and second hooks 39 and 40 is to be used again, the second
Since the hook 40 is rotatable, when the L-shaped bending direction is turned inward, this second hook 40 is rotatable.
Since the electric cord hooked on the hook 40 can be removed at once, it can be removed more quickly than unwinding it.

Furthermore, when the vacuum cleaner main body 1 is attached to the support 31 for cleaning, the first and second hooks 39 and 40 are located on the lower surface side, so that these hooks 39 and 40 are closed during operation.
．． 40 will not get caught on clothes etc.

In addition, in this embodiment, a second changeover switch 62 is provided,
When the vacuum cleaner main body 1 is attached to the mounting part 32, this second
The changeover switch 62 is turned off and the rechargeable battery 61 cannot be used. However, if this second changeover switch 62 is not provided, the vacuum cleaner main body 1 cannot be used by being attached to the attachment part 32 of the support body 31. In this case, either alternating current or direct current can be used by selecting with the first changeover switch 56. Therefore, if the electric cord 44 is not long enough and can be operated with DC current from the DC power supply circuit 54 even in a place where the suction port 34 of the support body 31 cannot reach, the electric cord 44 can be disconnected from the indoor outlet. You can clean by going to hard-to-reach places.

〔Effect of the invention〕

According to the present invention, in a stick-type vacuum cleaner including a handy-type vacuum cleaner body and a support body having a mounting portion to which the vacuum cleaner body is attached, the electric cord of the support body is connected to the support body. Since the cord is wound and stored in a wrapping part formed on a different surface from the attachment part, it is easy to store and remove the cord, and it can be stored in an attractive manner. The cord does not become an obstacle when attaching and detaching the vacuum cleaner main body during use, and furthermore, if the attachment part is provided on the front of the support and the wrapping part is provided on the back, the vacuum cleaner main body can be supported. When used by being attached to an attachment part of the body, the wrapping part does not get caught on clothes or the like.
