Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control cleaner which can be driven freely by a remote control to clean a narrow space in a room.

[0002]

2. Description of the Related Art A conventional floor-moving vacuum cleaner has a cleaner body and a dust collecting chamber (a connection opening communicating with the cleaner body).
, An extension pipe (pipe) detachable from the tip of the flexible hose, and a floor nozzle connected to the extension pipe (not shown).

At the time of cleaning, a hose, an extension pipe, and a floor nozzle are respectively connected to the cleaner body in advance to assemble the cleaner. After this, the cord of the cleaner itself (plug in)
To a power outlet. Then, the extension tube is gripped so that the tip of the floor nozzle is brought into contact with an appropriate place on the floor, and in this state, the tip of the floor nozzle is rubbed to suck and clean the dust on the floor.

[0004]

In a conventional floor-moving vacuum cleaner, a flexible hose, an extension tube, and a floor nozzle must be connected to the cleaner body before use. The work is troublesome. In particular, when cleaning the dirt of only a part of the room, this assembling and connecting work cannot be perceived to be more troublesome. At the end of the cleaning, the components must be disconnected and disassembled again.

Further, the external dimensions of a vacuum cleaner in which a long hose, an extension pipe and a floor nozzle are integrally connected to the main body of the vacuum cleaner are very large. For this reason, it is difficult to clean a small room in which many pieces of furniture are mixed and the top surface of a piece of furniture, and it is usually left unclean.

Further, it is difficult to clean the space below the bed in the room because the extension tube is in the way. In particular, the area around the hospital bed and the space under the bed where the inpatient lays can be used with a large floor moving vacuum cleaner because of noise, exhaust, etc., so that it is hardly cleaned and extremely dirty. It is.

The present invention solves the above problems, eliminates the need to connect hoses and extension pipes to the main body of the vacuum cleaner, and removes dirt in small rooms and gaps by simple operation using a remote controller. It is an object of the present invention to provide a remote controller cleaner that can be easily cleaned.

[0008]

In order to achieve this object, a remote-control cleaner according to the present invention has the following configuration. The remote control cleaner includes a remote controller and a cleaning body that freely travels in response to a command signal from the remote controller. The cleaning body includes a body having a power supply unit and a motor, and a body having a motor. A dust collection chamber with an open / close cover that has a floor nozzle opening with a freewheel provided on the bottom surface, a valve that communicates with the floor nozzle opening at the front to prevent backflow of dust, and a dust collection filter at the rear. And a suction fan provided outside the dust collection chamber, and an exhaust pipe communicating with the dust collection chamber via the suction fan.

[0009] In the remote control cleaner having such a configuration, the joystick (operation lever) of the remote control operation device is used.
By operating the, the cleaning traveling body can be arbitrarily run.

When the cleaning traveling body starts traveling (the driving motor is driven), the suction fan is driven at the same time. In other words, when the cleaning traveling body travels on the floor of the room, the suction fan operates at the same time, and the dust is sucked into the airflow duct of the cleaning traveling body (body body) together with the outside air.

That is, dust on the floor surface is sucked together with the outside air from the opening of the floor nozzle portion closest to the floor surface. The sucked outside airflow (airflow containing dust) is guided to the dust collection chamber via the valve body, collected by the dust collection filter, and stays in the chamber. The airflow that has passed through the dust collection filter is exhausted to the outside through an exhaust port of an exhaust pipe via a fan outside the chamber.

Therefore, in cleaning, it is only necessary to operate the operation levers of the remote controller to move the cleaning traveling body arbitrarily. Therefore, the vacuum cleaner itself is compact,
Not only can it be used in a space of a small room where many furnitures are mixed, but dust in a narrow gap between adjacent furnitures can be easily collected.

Furthermore, since the movement of the cleaning traveling body is performed by remote control operation, anyone can easily execute the movement, and at the same time, the child enjoys the remote control operation, and at the same time, cleans his / her own child room. You can keep the room clean.

In this case, when the cleaning traveling body 1 enters into a narrow space which cannot be seen from the outside at all, the cleaning is performed while confirming whether there is any dust on the back side with the screen cleaner of the remote controller 2. The advance of the traveling body 1 can be operated.

[0038]

According to the present invention, as described above, the cleaning traveling body is arbitrarily moved by operating the remote controller, so that the cleaning body can be flexibly attached to the cleaner main body like a conventional floor-moving vacuum cleaner. There is no need to connect and assemble the flexible hose, the extension pipe, and the floor nozzle, and the troublesome connection action can be eliminated. In addition, it is not possible to easily use a small room that cannot be used with a large-sized vacuum cleaner that requires a large three-dimensional space for use, and it is possible to clean not only the gap between furniture but also the top surface of the top plate of furniture. Further, since dust is collected by moving the cleaning traveling body by remote control operation, it is possible to very quietly and quickly clean the periphery of the bed where the patient lies, such as a hospital, and the space under the bed. Further, since the cleaning traveling body is modeled on the appearance of an F1 race car, a child or the like can enjoy his / her remote control operation and simultaneously clean his / her own children's room. Furthermore, since the power source of the cleaning traveling body is a storage battery, it can be charged from a commercial power source, the cord is not required for cleaning, and the cleaning operation is further simplified.
