More specifically, the mounting portion 38 protrudes from the edge of the first surface 320 in the width direction. The mounting portion 38 may have a ring shape in which a hole is formed in the center thereof. Similarly, the number of mounting portions is not limited, but at least two mounting portions are preferably formed to firmly fix the screen member.

According to another embodiment of the present invention, as shown in Figures 8a and 8b, the screen member 30, 130, 230 may be fitted with a fitting portion 40 that can be fitted to the lower side. The fitting portion 40 is fixed portion 42; And a shrinking portion 44 capable of shrinking the thickness of the fitting portion 40. As in other embodiments, there is no limit to the number of fittings, but at least two fittings are preferably formed to secure the screen member.

Hereinafter, various embodiments of the coupling part 50 formed on the surface 28 and the coupling of the screen member 30, 130, 230 and the coupling part 50 will be described.

According to another embodiment of the present invention, as shown in FIG. 9, the coupling portion formed on the innermost top surface 28 of the refrigerating compartment door may be the magnet member 150. In the screen members 30, 130, and 230, a magnetic material 46 may be embedded in one side or the first surface 320 for coupling with the magnet member 150, and the magnetic material embedded in the first surface 320. 46 and the magnet member 150 are aligned so that both can be combined. In this case, the screen member may be firmly fixed, and at the same time, the detachable and clean beauty may be provided.

According to another embodiment of the present invention, as shown in FIG. 10, the coupling portion may be a substantially cylindrical hollow 250 penetrating a predetermined depth through the innermost top surface 28 of the refrigerating compartment door 24. In addition, a thread may be formed on an inner circumferential surface of the hollow 250. The hollow 250 is arranged in alignment with the through-holes 36 of the screen members 30, 130, 230, and combines the screen members 30, 130, 230 through the fastening member 60, the thread is formed on the outer peripheral surface Let's do it.

According to another embodiment of the present invention, as shown in FIG. 11, the engagement portion may be a protrusion 350 protruding from the top surface 28. The protrusion 350 is shown in an enlarged one side view of FIG. The protrusion 350 includes a first portion 360 protruding from the top surface 28 of the interior of the refrigerating compartment door and having a first diameter; And a second portion 370 protruding from the first portion 360 and having a second diameter that is greater than the first diameter; And a cutout part 380 penetrating at least a portion of a center portion of the first part 360 and the second part 370. The protrusion 350 may be coupled to the through hole 36 formed in the screen members 30, 130, and 230. According to another example, the protrusion 350 may be coupled to the mounting portion 38 of the screen member (30, 130, 230). The diameter of the through hole 36 or the inner diameter of the mounting portion 38 is smaller than the outer diameter of the second portion 370 so that the cutout portion when the through hole 36 or the mounting portion 38 is engaged with the protrusion 350. As the 380 contracts, the through hole 36 or the mounting portion 38 is coupled to the first portion 360 by passing through the second portion 370. The configuration of the protrusion 350 facilitates detachment and at the same time prevents the mounted screen member from being accidentally separated.

In addition, as shown in FIG. 12A, in accordance with another embodiment of the present invention, the engagement portion may be a groove 450 recessed to a certain depth at the top surface 28.
