This design is based on the fact that the use of the space on the upper surface is not suitable due to the opening of the upper door due to the nature of the lid-shaped Yangmun Kimchi refrigerator which is used in kitchens of general homes and restaurants. First, the bottom surface of the sliding lower plate 30, which aligns the left and right sides of the rail, is fixed to the upper surface of the side door of the lid-shaped two-sided kimchi refrigerator 10 with a double-sided tape. After the door is completely opened, the sliding roof rail (60) is pushed horizontally outward from the inside of the sliding lower rail (40), and then the sliding door is moved left and right by closing one door . Thereafter, when the upper surface of the sliding upper plate 50 and the rotary shaft 90 of the 180-degree rotary shelf 70 are fixed with a bolt nut, 180 degrees rotation is also possible. At this time, the 180-degree rotating shelf 70 is a 180-degree rotating shelf rotatable by 90 ° to the front which is the user direction when the rotary knob 80 is on the left or right side of the rotation axis coinciding with the rail direction, Prevention guard rails 100 are also provided on four sides of the upper surface of the main body 70 in order to prevent the display products from falling when moving left and right and rotating. When the above is completed, the usage method is as follows. First, the left and right doors of the Kimchi refrigerator are opened in a situation where the rotary knob 80 is on the right side of the rotary shaft 90 from the front of the user. In this situation, when you want to open the left door of the Kimchi refrigerator, pull the rotary knob 90 degrees toward the user, send the top of the rail to the right side, open the left door of the Kimchi refrigerator, and open the right door of the kimchi refrigerator If you want to do this, pull the rotary knob 90 degrees toward the user, send the top of the rail to the left side, and open the right door of the K
