The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner having a vacuum motor and a rechargeable vacuum tank without a power source for driving the vacuum cleaner.

A general vacuum cleaner is provided with a vacuum motor, which sucks and removes dust and the like on the surface to be cleaned by the suction force generated by the vacuum motor being driven. Therefore, an AC or DC power supply for driving the vacuum motor must be provided.

A typical example of such a general vacuum cleaner is schematically illustrated in FIG. 1. The illustrated vacuum cleaner is a so-called handy vacuum cleaner, which uses a DC power source to drive the motor, which is suitable for short-term partial cleaning operations and has the advantage that it can be used anywhere while the battery is charged. . However, since the battery can not be used during discharge, the battery should be charged at regular intervals.

As shown in FIG. 1, the vacuum cleaner includes a suction head 1 and a cleaner body 2.

The suction head 1 is detachably mounted to the cleaner body 2. The suction hole 3 is formed in the lower end of the suction head 1, and the dust bag 4 and the filter 5 are attached inside.

In addition, the vacuum cleaner as described above is provided with a charger 10 for charging during discharge of the battery (7).

In the vacuum cleaner configured as described above, the vacuum motor 6 is driven by the power applied from the battery 7, so that the suction force is generated, whereby the dust on the surface to be cleaned is sucked through the suction hole 3 of the suction head 1. Dirt or the like is sucked into the dust bag 4 and collected. At this time, if the cleaning is performed for a predetermined time, the battery 7 is discharged and cannot be used. At this time, the terminal 10a of the charger 10 is inserted into the terminal hole 2a provided in the main body 2, and the battery 7 ) Is used after charging.

However, the above-described general vacuum cleaner has a structure in which a predetermined suction force is generated by using the vacuum motor 6 driven by driving power, and the vacuum motor 6 and the battery are necessarily inside the cleaner body 2.

In addition, the inlet opening and closing means 50 is provided in the button 51 installed to protrude to the upper portion of the vacuum tank 30, and the space portion 52a formed below the button 51, the button 51 Spring 52 for elastically supporting upward and extending from the lower portion of the button 51 to the inlet 32 is formed to open and close the inlet 32 while moving up and down in conjunction with the operation of the button 51. It is comprised by the opening and closing board 53. Here, the opening and closing plate 53 is initially in a state of blocking the inlet 32 by being elastically supported by the spring 52, and when the button 51 is pressed in such a state, the opening and closing plate 53 is lowered. The suction port 32 is opened so that the suction action of air through the suction head 20 is performed by the vacuum pressure of the vacuum tank 30. A handle 35 for handling a cleaner is formed at one side of the vacuum tank 30 in which the button 51 is located.

On the other hand, the vacuum charger 60 is for charging when the vacuum pressure in the vacuum tank 30 is released, the vacuum tank mounting portion having a hole (61a) in communication with the filling valve 40 of the vacuum tank 30 ( A charger body 63 having a 61 formed at an upper portion and an air discharge hole 62 formed at a side thereof, and a fan 64 installed at the charger body 63 to suck and discharge air in the vacuum tank 30, is provided.

Hereinafter, the operation of the cleaner according to the present invention configured as described above will be described.

First, in order to vacuum-fill the vacuum tank 30, when the vacuum tank 30 is mounted on the vacuum charger 60, the sensing sensor 72 installed in the mounting portion 61 of the vacuum charger 60 is pressed to operate the vacuum The control box 73 is notified that the tank 30 is mounted, and the motor 65 is driven by the drive signal of the control box 73.

The fan 64 is rotated as the motor 65 is driven, and the filling valve 40 installed at the rear of the vacuum tank 30 is opened by the suction force due to the rotation of the fan 64, and the vacuum tank 30 is opened. As the air inside is discharged through the air discharge hole 62, the inside of the vacuum tank 30 is in a vacuum state. The charging time of the vacuum tank 30 depends on its capacity, but can be drastically reduced compared to the time required for charging the battery. Therefore, it is particularly suitable for instant and sudden fresh water.

At this time, when the degree of vacuum in the vacuum tank 30 reaches a set value, the pressure sensor 71 installed in the vacuum tank 30 informs the control box 73, and the motor in the control box 73 The drive of 65 is stopped.

That is, when the suction button 20 mounted on the front of the vacuum tank 30 is pressed against the surface to be cleaned, the button 51 is moved, and the inlet port 53 of the negative pressure chamber 31 moves downward. 32 is opened, so that the air inside the suction head 20 is sucked into the inside through the suction port 32 of the vacuum tank 30 in a vacuum state. Therefore, dust or dirt accumulated on the surface to be cleaned is sucked through the suction hole 21 of the suction head 20 and collected in the dust bag 22. At this time, the suction air is introduced into the vacuum tank 30 as it is.

As described above, since the intake air continues to flow into the vacuum tank 30, if the cleaning for a predetermined time, the vacuum in the vacuum tank 30 is released. Then, as described above, the vacuum tank 30 is mounted on the vacuum charger 60 to be used again after vacuum charging.
