Abstract

PURPOSE:To automatically stop the operation of a vacuum cleaner, whenever a cleaning work is interrupted, by providing the holding section of a body with a switch for stopping the operation of an electric blower at the time of putting a holder on an extension in a service condition. CONSTITUTION:A holder 9 formed on the second extension hose 7 is inserted in the holding section 10 of a cleaner body 1, when a user temporarily goes away from a clearer during a cleaning work. In this state, a hose 3, the first and second extension hoses 6 and 7, and a floor brush 8 come to be kept upright and held in such a condition as connected to a cleaner body 1, and the handle 5 of the hose 3 comes to a position easy for a user's holding. When the holder 9 is inserted in the section 10, a switch 11 is operated and a control circuit saves the state of output to a drive circuit, thereby sending a signal to the drive circuit for stopping an electric blower. In starting again a cleaning work, the holder 9 is pulled out of the section 10 and the switch 11 is thereby operated. In addition, the control circuit actuates the drive circuit in the state of the saving output, thereby enabling the cleaning work to be again started with the same suction force as before, and further enabling a convenience for use to be improved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an electric vacuum cleaner capable of temporarily holding a hose and an extension pipe especially when cleaning is interrupted.

[0002]

2. Description of the Related Art Conventionally, as an electric vacuum cleaner for temporarily holding a hose and an extension pipe, for example, Japanese Patent Laid-Open No. 4-8331 (A47L)
9/00) is known. In this vacuum cleaner, when removing obstacles such as furniture or doing other tasks during cleaning, hold the holder provided on the extension tube in the holding part formed on the cleaner body and use it again. The hose and the extension pipe can be held so that the handle portion of the hose is located at a height where it can be easily gripped.

However, in this configuration, it is necessary to operate the control switch every time the cleaning is interrupted to turn off the power and set the suction force according to the surface to be cleaned when cleaning again, which is not convenient. was there.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an electric vacuum cleaner which can improve the convenience of use when cleaning is interrupted.

[0005]

The first means of the present invention is to:
A cleaner main body having a built-in electric blower, a hose connected to an intake port formed in the cleaner main body, an extension pipe connected to the hose, and a floor suction tool connected to the extension pipe,
The cleaner body is provided with a holding portion for detachably holding the holder provided on the extension tube, and the holding portion is provided with a switch for stopping the driving of the electric blower when the holder is attached. .

A second means of the present invention is a control switch which has a cleaner body having an electric blower built-in, one end connected to a suction port formed in the cleaner body, and the other end which controls driving of the electric blower. A hose provided with a handle portion, an extension tube connected to the other end of the hose, a floor suction tool connected to the extension tube, and a holder provided on the extension tube and attached to a holding portion formed in the cleaner body. A holder that is freely held, a switch that is provided in the holder of the cleaner body and that outputs the mounting state of the holder, and based on the output of the switch, stores the driving state of the electric blower when the holder is mounted. It is characterized in that a control circuit for cutting off the electric power to the electric blower and for re-driving the electric blower in the driving state stored when the holder is removed is provided.

[0007]

According to the first means of the present invention, when temporarily leaving the vacuum cleaner, for example, when organizing items in the room during cleaning,
The holder formed on the extension tube is held by the holder of the cleaner body. In this state, the hose, extension pipe, and floor suction tool are erected and held in a state of being connected to the cleaner body, and the handle of the hose is located at a height that is easily gripped by the user. By inserting the holder into the holder, the switch is operated and the electric blower is stopped.

According to the second means of the present invention, during cleaning,
When temporarily leaving the cleaner, such as when organizing indoors, the holder formed on the extension tube is held by the holder of the cleaner body. In this state, the hose, extension pipe, and floor suction tool are erected and held in a state of being connected to the cleaner body, and the handle of the hose is located at a height that is easily gripped by the user. By inserting the holder into the holder, the switch is operated and the control circuit stores the drive state of the electric blower and stops the electric blower.

When the holder is removed from the holder, the switch is operated, the electric blower is driven in the drive state stored in the control circuit, and the operation is resumed with the same suction force as before the interruption.

[0010]

An embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a cleaner body having a built-in electric blower 16, which has a suction port 2 formed on the front surface thereof. A hose 3 is detachably connected to the suction port 2 at one end thereof, and has a handle 5 having a control switch 4 for controlling driving of the electric blower 16 at the other end. 6 is a first extension pipe detachably connected to the other end of the hose 3, 7 is a second extension pipe detachably connected to the first extension pipe 6, and 8 is a detachable connection to the second extension pipe 7. The second extension pipe 7 is a floor suction tool that is freely connected.
A holder 9 is detachably held by a holder 10 of the cleaner body 1 described later.

Reference numeral 10 denotes a holding portion formed on the rear portion of the side surface of the cleaner main body 1, and by inserting and holding the holding tool 9, the hose 3, the first and second extension pipes 6 and 7, and the floor suction tool 8 are provided. It can be held upright while being connected to the cleaner body 1. Reference numeral 11 denotes a switch provided on the holding portion 10, and the operating portion 12 is arranged at a position operated by inserting the holding tool 9 into the holding portion 10.
The insertion status to 10 is output.

Next, the circuit will be described with reference to FIG.
Is a control circuit consisting of a microcomputer, and a power supply circuit
The constant voltage is supplied from 14. The control circuit 13 inputs the outputs from the control switches 4 and 11, controls the electric blower 16 via the drive circuit 15, and displays the driving state of the electric blower 16 on the display unit 17. There is.

Thus, when temporarily leaving the cleaner, such as when cleaning up the items in the room during cleaning, the holder 9 formed on the second extension tube 7 is attached to the holder 10 of the cleaner body 1. insert.
In this state, the hose 3, the first and second extension pipes 6 and 7, and the floor suction tool 8 are held upright while being connected to the cleaner body 1, and the handle 5 of the hose 3 can be easily grasped by the user. Located at height.

By inserting the holder 9 into the holder 10, the switch 11 is operated, the control circuit 13 stores the output state to the drive circuit 15 and outputs a signal to the drive circuit 15 to stop the electric blower 16. To do.

When cleaning is performed again, the holder 9 is attached to the holding portion.
When pulled out from 10, the switch 11 is operated and the control circuit 13
The drive circuit 15 is driven in the output state memorized by, and the operation is restarted with the same suction force as before the interruption.

[0017]

According to the structure of claim 1 of the present invention, the operation can be stopped without operating the control switch every time the cleaning is interrupted, and the convenience of use can be improved. Play.

According to the second aspect of the present invention, the operation can be stopped without operating the control switch each time the cleaning is interrupted, and the operation can be restarted with the same suction force as before the interruption. Therefore, it is possible to improve the usability.
