Description

Vacuum cleaner with individually adjustable height of dust brush roller and mop brush roller

The present invention relates to a cleaner capable of individually adjusting the heights of a dust brush roller and a wet mop brush roller, and more particularly, the height of a dust brush roller for sucking dust on the floor and a wet mop brush roller for cleaning the floor with water and a vacuum cleaner capable of performing suction cleaning and water cleaning more efficiently by individually controlling the operating speed.

A vacuum cleaner refers to a device that removes air or dust or contaminants from a point to be cleaned by suctioning or sweeping using power generated by a motor mounted on a cleaner body or a nozzle.

Such vacuum cleaners are classified into canister cleaners, upright cleaners, stick cleaners, handy cleaners, and robot cleaners. The canister cleaner is provided with a suction nozzle for sucking dust separately from the cleaner body, and the cleaner body and the suction nozzle are connected to each other by a connecting device. The upright vacuum cleaner has a type in which the suction nozzle is rotatably connected to the cleaner body.

In the case of stick cleaners and handy cleaners, in which users hold the cleaner body by hand, the number of users is steadily increasing due to the recent increase in single-person households and convenience of use or storage.

A characteristic of the stick vacuum cleaner is that the suction motor is disposed close to the suction nozzle (lower center), and in the case of a handy vacuum cleaner, the suction motor is disposed close to the grip part (upper center).

The suction nozzle refers to the part that touches the floor and directly sucks in dust and air. The suction power generated by the suction motor mounted inside the cleaner body is transmitted to the suction motor, and dust and air are sucked into the suction nozzle by the suction power.

The suction nozzle is equipped with a roller (or agitator), which facilitates the suction of dust or dirt. The rollers play a role in improving the dust collection performance of the vacuum cleaner by scraping off dust from the floor or carpet while rotating.

A brush is attached to the roller, and the brush of the roller causes friction with the floor or carpet, making it easier for the nozzle to suck in dust or foreign substances.

On the other hand, even when cleaning by sucking foreign substances on the floor with a roller, it is necessary to mop because old dirt or viscous substances on the floor do not stick to the floor and fall off. However, if you mop yourself, your back and knees will not only hurt, but even if you mop after removing the moisture, the floor will become dry with water, and sometimes you have to rub it vigorously several times to remove it, which consumes a lot of stamina. In order to solve this problem, a cleaner equipped with a roller or a roller-type brush attached to the surface such as a wet mop capable of cleaning with water, like a dust brush roller, is used.

However, in the case of a wet mop vacuum cleaner according to the prior art, since the dust brush roller having a suction function and the wet mop brush roller serving as a water cleaner are mounted at the same height, the wet mop brush roller absorbs dust There was a problem in that the suction of the brush roller was prevented so that the suction was not efficient.

However, when the power of the vacuum cleaner is turned off, there may be cases in which substances existing on the floor are attached to the wet mop brush roller due to the viscous specificity of the wet mop brush roller, or foreign substances remain on the floor because suction is not completed. In this case, foreign substances attached to the wet mop brush roller fall to the floor in the process of cleaning the vacuum cleaner, or the user has to re-clean the unsucked foreign substances remaining on the floor.

However, even when the vacuum cleaner 100 according to the present invention receives a power-off command from the user, as shown in FIG. 10 , the operation of the wet mop brush roller motor 40 stops, but the operation of the dust brush roller motor 10 is maintained for a certain period of time (tx) to absorb the foreign substances remaining on the floor or to absorb the foreign substances remaining on the wet mop brush rollers (50, 60), so that the user does not clean the remaining in the process of cleaning the vacuum. We can provide an environment that does not

In addition, when a power-off command is received from the user, in addition to the speed of the dust brush roller motor 10 in order to efficiently remove foreign substances remaining on the floor, the suction motor 120 in the body 11 It is possible to more efficiently absorb the dust on the floor surface by increasing the suction speed of the

10 is a diagram illustrating a state in which a rotation direction of a dust brush roller is changed according to an operation direction of a cleaner according to another embodiment of the present invention.

In general, when cleaning while the user pushes the vacuum cleaner forward, the direction of the rollers is shown in FIG. It is efficient to rotate from the outside to the inside as shown. Accordingly, since the rotation direction of the dust brush rollers 20 and 30 is generally fixed in one direction, there is a disadvantage in that cleaning efficiency is lower than when the vacuum cleaner is pushed while pulling.

However, the cleaner 100 according to the present invention controls the dust brush roller motor 10 and the wet mop brush roller motor 40 to rotate the dust brush rollers 20 and 30 and the wet mop brush rollers 50 and 60 in the rotation direction. can be individually controlled, the cleaning efficiency can be improved by controlling the rotation directions of the dust brush rollers 20 and 30 and the wet mop brush rollers 50 and 60 differently depending on the operating direction of the cleaner 100 .

Specifically, as shown in FIG. 10(a), when the cleaner 100 pushes forward and cleans, the dust brush rollers 20 and 30 are rotated in the rotation direction from the outside to the inside to efficiently remove the dust. In the case of cleaning in the direction in which the cleaner 100 pulls, on the contrary, as shown in FIG. As always, there is an advantage of efficiently absorbing dust.

Up to now, the components and control method of the cleaner 100 according to an embodiment have been described in detail through the drawings.

In the vacuum cleaner capable of individually adjusting the heights of the dust brush roller and the wet mop brush roller according to an embodiment, the height of the dust brush roller is lower than the height of the wet mop brush roller when the vacuum cleaner operates in the suction mode, and operates in the water cleaning mode In this case, the height of the wet mop brush roller is lower than that of the dust brush roller, so that both suction and water cleaning can be efficiently cleaned.

In addition, the vacuum cleaner capable of individually adjusting the height of the dust brush roller and the wet mop brush roller according to an embodiment stops the operation of the wet mop brush roller when the suction mode operates, and the dust brush when the cleaner operates in the water cleaning mode By stopping the operation of the roller, there is an advantage of increasing the efficiency of power and at the same time increasing the cleaning efficiency.

In addition, the vacuum cleaner capable of individually adjusting the height of the dust brush roller and the wet mop brush roller according to an embodiment operates the dust brush roller for a certain period of time even when the power of the cleaner is turned off, so that the remaining floor surface and There is an advantage of efficiently removing the dust remaining on the wet mop brush roller.
