Description

The present invention relates to a floor cleaner, and more particularly, to a self-propelled cleaner that can be automatically moved and cleans dust on the floor.

In ordinary houses and offices, the floor often has minute dust. In order to clean these fine dusts, the cleaning is usually performed by washing or artificial work using a cleaner. In this way, the control of human power is required, which puts a burden on the work on the worker and increases the number of personnel. As a prior art for reducing or avoiding the burden of manpower, a random cleaning operation can be performed on the floor surface by attaching a driving mechanism capable of randomly changing the direction and a cleaning fabric under the top cover with a locking system. A possible mobile robot is disclosed in Chinese Patent No. ZL01818059.0. The cleaning fabric is flexible, and when moved to an adjacent surface such as a corner of a wall, a portion of the cleaning fabric is raised by pressing and can be cleaned against the corner of the wall. Further, the top cover itself can be formed as a vacuum suction device, and fine dust on the floor can be cleaned by performing a dust suction operation on the floor.

However, the above-mentioned prior art has the following problems.
1. When the cleaning work is performed, the cleaning fabric attached to the top cover at the time of movement is folded, so that it cannot be brought into close contact with the floor, resulting in a loss of cleaning effect.
2. When the floor is cleaned, if the piece of cleaning fabric slips into the gap between the floor and the object on the floor, it will be caught or blocked, and the cleaning operation must be interrupted.
3. Since the surface of the cleaning fabric is cleaned according to the degree of bulging of the cleaning fabric, there is often a non-uniform phenomenon in the cleaning range of the adjacent surface.

Chinese Patent No. ZL0188159.0

Therefore, an object of the present invention is to provide a self-propelled cleaner that can be cleaned in close contact with the floor and can efficiently clean the floor without being caught.

In order to achieve the above-described object, a self-propelled cleaner according to the present invention includes an upper lid, a holder, a random direction changing drive mechanism, a pedestal, and a floor surface contact plate. The upper lid is coupled to the pedestal. The pedestal is provided with at least one through hole, an opening is formed in the center of the pedestal, and a flange is formed on the outer periphery of the opening. A holder cover extends downward from the periphery of the holder, the holder cover is covered with a flange of the pedestal, and a swirl space is formed between the inside of the holder cover and the opening, and the top surface of the holder Is provided with an electric machine base and a power supply device. The random direction changing drive mechanism includes an electric machine and a drive wheel set, the electric machine is attached to the electric machine base, the drive wheel set is joined to the electric machine, and the drive wheel set is freely in the turning space. It can rotate. The self-propelled cleaner is randomly moved on the floor by driving the random direction changing drive mechanism. The floor surface contact plate is coupled to the bottom surface of the pedestal, so that when the self-propelled cleaner is operating, the floor surface contact plate can be in close contact with the floor and cleaned. Further, a hook-and-loop fastener for adhering the dust removing paper is provided on the bottom surface of the floor surface contact plate. The size of the dust removing paper is assumed to be substantially the same as the bottom surface of the floor contact plate so that the dust removing paper does not get caught in the gap. Further, cleaning villus may be further provided outside the pedestal to clean the corners of the wall.

The effects of the self-propelled cleaner according to the present invention are as follows.
1. When the self-propelled vacuum cleaner according to the present invention is used, the floor surface contact plate descends due to gravity, so that the cleaning work can be performed while firmly contacting the floor.
2. Since the dust removing paper according to the present invention is in close contact with the floor contact plate when the floor is being cleaned, it is not folded during operation.
3. When the cleaning villus is placed on the self-propelled cleaner according to the present invention, the cleaning range extends from the bottom surface to the upper peripheral surface. There is no phenomenon, and it can be thoroughly cleaned with villi.

An exploded view of the present invention is shown. The exploded view of the random direction change drive mechanism concerning the present invention is shown. The exploded view of one Example concerning this invention is shown. FIG. 4 shows a partial cross-sectional view of the embodiment of FIG.

A swirling space 55 is formed between the inside of the holder cover 23 and the opening 54. The holder 20 is movably fixed to the pedestal 50 by being fixed with screws after the sliding column 51 is fitted with a spring through the receiving hole.

The random direction conversion drive mechanism 30 includes an electric machine 31 and a drive wheel set 40. In the electric machine 31, a normal speed reduction mechanism (not shown) and an output shaft 32 having an outer hexagonal shape are provided. The electric machine 31 is screwed to the electric machine base 21, and the switch 11, the power supply device 22, and the electric machine 31 are electrically connected.

When the driving wheel set 40 is pressed into and engaged with the electrical cover 33, the locking claw 431 is slightly elastically expanded and locked to the electrical cover 33. At the same time, the output shaft 32 is inserted into the transmission hole 421. Inserted and can transmit power. Since the driving wheel set 40 is located in the turning space 55 between the holder cover 23 and the opening 54, the driving wheel set 40 can freely turn in the turning space 55.

The floor surface contact plate 60 has an annular shape, a convex column 61 is provided on the top surface, and a surface fastener 62 for adhering the dust removing paper 70 is provided on the bottom surface. The convex column 61 is positioned by screwing a screw 63 to the end of the convex column 61 through the through hole 52. The size of the dust removing paper 70 is substantially the same as that of the floor surface contact plate 60 and is an annular shape, and therefore does not exceed the outer periphery of the floor surface contact plate 60.

As shown in FIGS. 3 and 4, in actual implementation, the switch 11 is turned on (the switch 11 can be set to stop operating when it reaches a predetermined time, for example, 15 minutes or 30 minutes). Next, when the self-propelled cleaner is placed on the floor surface, the random direction conversion drive mechanism 30 operates in contact with the floor surface, and the floor surface contact plate 60 descends due to gravity. Can adhere to the floor. When the random direction changing drive mechanism 30 is operating, the dust removing paper 70 is in close contact with the floor surface. Furthermore, since reverse torque occurs when the drive wheel set 40 is operating, the self-propelled cleaner rotates in a direction opposite to that of the drive gear 42. Since the dust removing paper 70 is in close contact with the floor surface, and the self-propelled cleaner rotates, the fine dust on the floor surface can be thoroughly cleaned.

5 and 6 show another embodiment of the self-propelled cleaner according to the present invention. In this embodiment, the self-propelled cleaner further includes cleaning villi 80.

An upper opening 81 is provided at the upper end of the cleaning villi 80, a lower opening 82 is provided at the lower end, and villi 83 are provided outside the cleaning villi 80. In actual implementation, the base 50 of the self-propelled cleaner is pushed into the cleaning villi 80 (the dust removing paper 70 may or may not be removed), whereby the lower wheel seat 41 and the switch 11 Is exposed to the outside, and the floor contact plate 60 is bundled on the bottom surface of the pedestal 50. With the addition of the cleaning villi 80, when cleaning with the self-propelled cleaner turned on, it is possible not only to clean the floor, but also to clean the adjacent surface such as the corner of the wall. it can. Further, by sewing an elastic band around the periphery of the upper opening 81 and the lower opening 82, the cleaning villus 80 can be surely brought into close contact with the self-propelled cleaner and the slide dropout may occur. Absent.
