Description

Cleaning apparatus

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaner, and more particularly, to a cleaner in which a pair of rollers in contact with each other touches a floor to collect dust or fallen leaves present on the floor.

A general vacuum cleaner is provided with a negative pressure source and a collecting bag in a main body, and is exposed to the floor, and collects solids, such as dust and fallen leaves, which exist on the floor through the hood by the negative pressure source.

However, since the cleaner collects the solids in the collecting bag only by the sound pressure source, when the solids contain moisture or have a large surface area, it is difficult to collect them in the collecting bag through the hood.

A cleaner for overcoming this problem is disclosed in Korean Patent Laid-Open No. 10-2004-0052094.

 The disclosed vacuum cleaner includes a pair of brushes rotatable in a state where the center of rotation axis is arranged in parallel to the hood, and the pair of brushes causes the pair of brushes to scrape the floor so that the solids on the floor (solids with moisture or a large surface area) are provided. Solids, etc.) are picked up and collected by the sound pressure source in the collection bag.

However, the above-described cleaner has a weak force to attract the solids present on the floor because the brushes that rotate in opposite directions to each other in the line contact with the floor, it is difficult to properly pull the solids into the collecting bag when the solids are heavy, In the case where the solid is powder, the rotating brush is curved by elasticity, and then the powder does not flow between the pair of brushes due to the spreading and is scattered out of the pair of brushes.

The present invention has a problem in solving the above problems.

According to the present invention, a pair of rollers rotating in a direction facing each other are rotatably mounted on a cleaner body, and at least one of the pair of rollers is variable so as to be in surface contact with the floor and at the same time the surface of the roller is variable. By making it contact, the said subject can be solved.

According to the present invention, a pair of rollers are variable by means of the above-described problem solving means, the surface contact with the floor to sweep the floor to move the solids between the pair of rollers, the moved solids are in surface contact with each other It is possible to reliably pass to the collection bag arranged between the pair of rollers on the discharge side of the pair of rollers, so that solids or large solids containing moisture can be collected in the collection bag more efficiently than before.

2 is a conceptual diagram of a cleaner of a second embodiment according to the present invention; and
3 is a conceptual diagram of a cleaner of a third embodiment according to the present invention;

Hereinafter, a cleaner according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

1, the cleaner of the first embodiment is indicated by reference numeral 100. In FIG.

The cleaner 100, the body 10 with a handle 11; A front roller (30A) and a rear roller (30B) rotatably mounted on the bottom of the main body (10) in a direction facing each other and in contact with the bottom of the cleaning object in a state of being in surface contact with each other; And an inlet is disposed at the discharge side A between the front roller 30A and the rear roller 30B to discharge at the suction side B (bottom) between the front roller 30A and the rear roller 30B; And a collecting part 40 provided in the main body 10 to receive the solids introduced into the main body.

The front roller 30A disposed on the front side in the traveling direction is a rigid roller whose appearance is not changed by external force, and is in linear contact with the floor to be cleaned.

The rear roller 30B disposed at the rear side of the driving direction is a variable roller whose shape is changed by the weight of the main body that is external force in contact with the floor, and is pressed in the vertical direction by the weight of the main body 10. Is in contact with the floor of the object to be cleaned.

The rear roller 30B may be a ring-shaped tube filled with a compressive fluid, a ring-shaped portion having elasticity such as a sponge, and the like.

The front roller (30A) and the rear roller (30B) is spaced apart in the running direction of the cleaner 100 in parallel to extend in parallel to the front rotary shaft (31A) and the rear rotary shaft (31B) rotatably mounted to the main body (10) It is fixedly circumscribed to each.

At one end of the front rotary shaft 31A and the rear rotary shaft 30B, each of the front gear 32A and the rear gear 32B, which are engaged with each other to rotate in a direction facing each other, is fixedly circumscribed.

The number of teeth of the front gear 32A is larger than the number of teeth of the rear gear 32B so that the rear roller 30B rotates faster than the front roller 30A.

The front roller 30A may be selectively driven by the motor by engaging the drive gear circumscribed to an output shaft of a motor (not shown) mounted on the main body 10 in the front gear 32A.

A chute 50 is disposed on the discharge side A and is fixed to the main body 10, and the tip of the chute 50 is in sliding contact with the front roller 30A and the rear roller 30B, and The proximal end of the chute 50 is connected to the inlet of the collecting part 40 so as to be able to flow.

Push or pull to move, and when the motor is provided in the cleaner 100, when the motor is operated while the front roller 30A is in contact with the floor by raising the back of the main body 10, the entire cleaner 100 Will move forward.

Then, when the user grasps the handle 11 and returns the inclined state of the main body 10 to its original position, the front roller 30A and the rear roller 30B touch the floor, and the rear roller 30B is connected to the main body ( It is pressed by the floor by the weight of 10) to be in surface contact with the floor is variable, and in this state to pull the main body 10, or to operate the motor, the front roller (30A) and the rear roller (30B) The solids existing on the suction side B therebetween are moved between the front roller 30A and the rear roller 30B to the discharge side A, and the solids moved to the discharge side A are separated from the chute 50. The guide is moved into the housing 40 or into the collecting bag 60.

If the accommodating part 40 is connected to the sound pressure source 70, the solid may be more easily accommodated in the accommodating part 40 or the collecting bag 60.

The reason why the main body 10 is moved backward even when the front roller 30A and the rear roller 30B rotate in a direction facing each other is that the rear roller 30B is larger than the contact area of the front roller 30A to the floor. This is because the contact area of) is large.

In addition, the rear roller 30B may be in contact with the bottom outer circumferential surface of the front roller 30A facing the bottom in the state where the rear roller 30B is in contact with the floor. In the state of rotating faster than the roller 30A, the rear roller 30B is in a free state and is continuously pressurized by the front roller 30A while being pressurized by the bottom to deform the inertia of the rear roller 30B. Because it occurs.

The cleaner 100 configured as described above moves the solids on the floor between the front and rear rollers 30A and 30B by sweeping the floor by the rear roller 30B being variable in surface contact with the floor, and the surface of the moved solids in contact with each other. It is possible to reliably pass between the front and rear rollers 30A and 30B, which are secured to the housing portion 40 disposed on the discharge side of the front and rear rollers 30A and 30B, so that solids or surface areas containing moisture are more efficiently than before. Large solids can also be reliably collected in the enclosure.

If the cleaning sheet is laminated on the outer circumferential surfaces of the front and rear rollers 30A and 30B, it is preferable in view of being able to mop and remove the dust on the floor while collecting solids such as dust in the house.
