A weighing type ice vending machine includes an ice cube formation device installed in a machine body for supplying a specific weight of ice cubes after coins are inputted, and a body composed of a storage bucket, an output device, a weight sensing module and a control loop. Pure water is put into an ice tray in the machine body and condensed into ice cubes which are gathered into a storage bucket for a cold storage. A user puts a user's container on a weighing scale of the weight sensing module at an outlet of the machine body outlet and inserts coins whose dollar amount information is displayed. The quantity of outputted ice cubes is calculated and outputted automatically, and then the ice supply is stopped. The quantity of remained ice cubes in the machine body is recorded automatically, such that the ice cube will be produced again timely and the supply of ice cubes will be stopped temporarily.
