Beschreibung
Zusammenfassung:	The utility model discloses a photoelectric frost sensor which comprises a base, a heat conductor, a light emitter, a light receiver, an upper cover board and a fixing element, wherein the base is a flat board with two heaves, a semi-cylindrical groove is arranged in the bottom side of the flat board, the heat conductor is nested in the groove of the substrate, the top part of the heat conductor extends out of the upper surface of the flat board of the substrate, the light emitter and the light receiver are respectively positioned in the inner sides of the two heaves of the base and connected with the upper cover board into a whole body, the upper cover board is connected with the two heaves of the base, and the base is connected with the fixing element. The base is made of an electric insulating material, a heat insulating material and the like, and the heat conductor is made of a heat conducting material. The photoelectric frost sensor has the effects of directly sensing the frost layer thickness of refrige
