BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein; It is intended that the disclosure of the present invention be limited only by the terms of the appended claims. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

First, the general structure of the dust collecting blade provided in the cleaning robot to which the present invention is applied will be described.

1 is a view for explaining the configuration of the body and dust container of a conventional cleaning robot, Figure 2 is a view showing the configuration of the dust container and the inflow path of the garbage shown in FIG.

Referring to FIG. 1, the cleaning robot to which the structure of the dust collecting blade according to the present invention is applied includes a moving robot body 1 and a dust container 20 coupled to the rear of the robot body 1. The rear of the robot body 1 is provided with a mounting space (1a) for mounting the dust container 20, the dust collecting blade 10 is formed in the lower front of the dust container (20).

Referring to FIG. 2, the dust collecting blade 10 is formed to be inclined downward along the garbage inlet 210 formed in the dust container 20, and when the dust container 20 is mounted on the robot body 1, the robot body 1 is formed. It is located at the bottom of the). Such a dust collecting blade 10 is preferably made of an elastic material such as rubber. This is to easily overcome obstacles such as thresholds or carpets while the cleaning robot is running.

FIG. 3 is a view illustrating a conventional dust collecting blade, and FIG. 4 is a view illustrating a state in which the dust collecting blade illustrated in FIG. 3 is folded backward.

Referring to FIG. 3, it can be seen that the dust collecting blade 10 is positioned in contact with the rear of the brush 30. When the brush 30 is rotated, the garbage on the carpet CA flows into the dust container 20 along the dust collecting blade 10 disposed at the rear of the brush 30. The end of the dust collecting blade 10 is formed to be inclined downward downward, it is configured to minimize the separation with the brush (30).

Referring to FIG. 4, when the cleaning robot travels on the carpet CA, due to the carpet ridge, the end of the dust collecting blade 10 is folded in the opposite direction in the driving direction. In this case, the garbage on the carpet CA does not flow into the dust container 20 along the dust collecting blade 10, and remains between the brush 30 and the dust collecting blade 10, thereby reducing the dust collecting performance of the cleaning robot. Floating problem occurs.

The present invention, to improve the problem of such a dust collecting blade (10). It is a main technical feature to propose a support for supporting the dust collecting blade 10 from the rear.

FIG. 5 is a view illustrating a support part integrally formed at the bottom of the dust container as a first preferred embodiment of the dust collecting blade structure of the cleaning robot according to the present invention.

FIG. 5 shows only the parts which are characterized in order to conceptually clearly understand the configuration relations for the preferred embodiments of the present invention, and as a result, various modifications of the drawings are expected, and the present invention needs to be greatly limited to the specific forms shown. There is no.

5, a preferred embodiment of the dust collecting blade structure of the cleaning robot according to the present invention includes a dust collecting blade 100 and a support 200 supporting the dust collecting blade 100 so as not to be folded backward.

The support part 200 is formed on the bottom surface of the dust container 20 to which the dust collecting blades 100 are fixed, and the ends thereof are formed to be in contact with the rear surface of the dust collecting blades 10. Thus, the support 200 may be formed of one member long along the width of the dust collecting blade 100, but the present invention is not limited thereto, and is formed of a plurality of members arranged along the width of the dust collecting blade 100. It may be.

The support 200 may be integrally formed with the dust container 20 or may be formed as a separate part from the dust container 20.

First Embodiment

First, when the dust collecting blades 100 are integrally formed with the dust container 20, the dust collecting blades 100 extend from the bottom surface 22 of the dust container 20 so that their ends are bent toward the rear surface of the dust collecting blades 10. It is injection molded integrally with the dust container 20.

As can be seen in Figure 5, because the end of the forward support 200 is in contact with the rear surface of the dust collecting blade 100, to maintain a constant distance between the brush 30 and the dust collecting blade 100, The dust collecting blade 100 is supported so as not to be bent backward.

The support part 200 may be injection molded from the same material as the dust container 20, but may be formed of a different material from the dust container 20 by a double injection molding method. At this time, the support portion 200 is preferably made of a material having a smaller elastic force and greater hardness than the dust collecting blade 100.

Second Embodiment

6 and 7 are diagrams for explaining a support unit coupled as a separate part to the bottom of the dust container as a second embodiment of the dust collecting blade structure of the cleaning robot according to the present invention.

When the dust collecting blade 100 is formed as a separate part from the dust container 20, the dust collecting blade 100 is coupled to the bottom surface 22 of the dust container 20 and its end is bent toward the rear surface of the dust collecting blade 10.

As shown in FIG. 6, as the support part 200, a separate elastic member may be coupled to the bottom surface 22 of the dust container 20. At this time, the elastic force of the support 200, should be configured to be lower than the dust collecting blade (10). On the other hand, as shown in Figure 7, the spring-shaped support 200 for generating a rotation moment forward with respect to C of Figure 7 may be illustrated.

At this time, the elastic force of the spring-shaped support 200 is properly designed so that the distance between the brush 30 and the dust collecting blade 10 is kept constant even when the cleaning robot travels on an obstacle such as a threshold or a carpet.

Embodiments of the support 200 shown in FIGS. 6 and 7 may be detachably formed on the bottom surface 22 of the dust container 20. Alternatively, the dust container 20 may be formed to be sunk and protrude only when necessary to support the dust collecting blade 100.

Meanwhile, referring to FIGS. 5 to 7, it can be seen that a plurality of protrusions 110 are formed on the rear surface of the dust collecting blade 100. The protrusion 110, together with the support part 200 described above, prevents the dust collecting blade 100 from being deformed from the elastic region to the plastic region by folding back the obstacle by the obstacle, and serves to reinforce the restoring force. When the dust collecting blade 100 is deformed into the plastic region, the restoring force is lost, so that the clearance between the brush 30 and the end of the dust collecting blade 100 is increased, thereby reducing the efficiency of inflowing garbage into the dust container.

The end of the support 200 as described above, is bent downwardly inclined forward to be caught by the protrusion 110. The shape of the end of the support 200 may be variously changed in size and shape in order to enlarge the contact area with the protrusion 110.

It has been described above with respect to the dust collecting blade structure of the cleaning robot according to the present invention and a preferred embodiment of the cleaning robot including the same.

It is to be understood that the above-described embodiments are illustrative in all aspects and should not be construed as limiting, the scope of the invention being indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
