Accordingly, the second step portion 252 may be formed long along the longitudinal direction of the coupling groove 25, and both ends may be rounded.

The coupling groove 25 may include a first penetration portion 259 (see FIG. 8) formed by penetrating approximately in the center of the second step surface 252a. Additionally, it may include a bracket fixing portion 253 extending along the circumference of the first penetrating portion 259 from the second step surface 252a toward the inside of the first penetrating portion 259 . The bracket fixing portion 253 is configured to prevent the magnet assembly 26, which will be described later, from being removed.

In addition, the bracket fixing part 253 may have a rectangular fixing hole 253a formed in the center. Accordingly, a portion of the second bracket 261 may be exposed through the fixing hole 253a.

(256) may be further included.

And, surrounded by the side support portion 255, the front support portion 256, and the rear support portion 254, an inlet space into which the magnetic assembly 26 is introduced may be formed. Accordingly, the lead-in space will have the same cross-sectional area as the first penetration part 259.

Meanwhile, the positions of the front support 256 and the rear support 254 are designed to express that they are formed at the front and rear, with the front support 256 formed at the rear and the rear support 254 formed at the front. It could be. Hereinafter, the description will be limited to an example in which the front support portion 256 is formed at the front and the rear support portion 254 is formed at the rear.

A locking portion 257 extending inward may be formed at an extended end of the rear support portion 254. The locking portion 257 is configured to prevent the magnetic assembly 26 from being removed, and may have a hook shape, for example.

A second penetrating portion 258 partially penetrating may be formed in the front support portion 256. In detail, the second penetration portion 258 penetrates the second step surface 252a and a portion of the front support portion 256 that is in contact with the second step surface 252a. Accordingly, the front support part 256 becomes relatively easy to bend, and by bending the front support part 256, it is possible to secure a space for inserting the magnetic assembly 26 into the introduction space.

The magnetic assembly 26 may include a magnet 262 and a second bracket 261. In addition, the magnetic combination body 26 may be formed, for example, with the magnet 262 interposed between two second brackets 261. And, the second bracket 261 may be a magnetic material. For example, the second bracket 261 may be made of iron.

Additionally, the total thickness of the two second brackets 261 and the magnet 262 may be equal to or slightly smaller than the gap between the front support portion 256 and the rear support portion 254.

In addition, although not shown, a protrusion is formed at the center of the second bracket 261 protruding toward the magnet 262, and a groove is formed in the magnet at a position corresponding to the protrusion so that the magnets can be coupled to each other. However, various methods of combining the second bracket 261 and the magnet 262 may be suggested by those skilled in the art.

The width of the magnet 262 may be equal to or slightly smaller than the distance between the side supports 255. Accordingly, the magnet 262 may be formed as a substantially rectangular parallelepiped.

A portion of the second bracket 261 may be formed to be equal to or slightly smaller than the distance between the side supports 255, and the remainder may be formed to be stepped so as to protrude through the fixing hole 253a. Accordingly, for example, the second bracket 261 may be formed to have an overall substantially rectangular parallelepiped shape and may be formed to protrude convexly from a portion where the fixing hole 253a is formed.

Additionally, the end surface from which the second bracket 261 protrudes may be formed to be flat. Accordingly, the second bracket 261 may be in surface contact with the first bracket 382 at a portion protruding through the fixing hole 253a.

Figure 8 is a cross-sectional perspective view schematically showing the coupling groove and coupling protrusion according to an embodiment of the present invention.

Referring to FIGS. 3 and 8 , when the suction grill 30 contacts the panel 20, the engaging protrusion 38 may be inserted into the engaging groove 25.

Accordingly, the second bracket 261, which is in contact with the magnet 262 and is magnetic, can be coupled to the first bracket 382 by magnetic force. Meanwhile, the magnetic force of the magnet 262 should be designed not to be too strong so that it is difficult for the user to separate the suction grill 30.

When the first bracket 382 and the second bracket 261 are coupled, the screw 383 may be located between the bracket fixing part 253 and the second step part 252. Of course, the screw hole 382a and the screw groove 381a should be formed at corresponding positions between the bracket fixing part 253 and the second step part 252. Accordingly, a portion of the screw 383 protruding to the outside of the second bracket 261 may be inserted into the space between the bracket fixing portion 253 and the second step portion 252 at a predetermined interval. Therefore, when the first bracket 382 and the second bracket 261 are combined, they do not interfere with each other and a narrow gap can be maintained.

Additionally, the weight of the panel 20 may be reduced by preventing the protrusion 32 from being formed below the center of the second bracket 261. However, if necessary, a reinforcement portion 385 may be formed to strengthen support for the second bracket 261.
