[0003] Reference announcement number CN212511943U is an easy-to-clean household refrigerator evaporator, which includes a heat exchange tube, a slide rod and a cleaning plate. Heat exchange fins are evenly arranged on the outside of the heat exchange tube, and the upper and lower ends of the heat exchange fins are connected to connecting plates. A support rod is installed at one end of the connecting plate away from the heat exchange fins, and the left and right ends of the support rod are connected to end blocks. The slide rod is installed between the adjacent upper and lower end blocks, and the outside of the slide rod is connected to a sleeve. One end of the connecting rod is fixed to the inner outer wall of the sleeve, and a bearing is installed at the other end of the connecting rod.
