PROBLEM TO BE SOLVED: To provide a steam generator capable of preventing clogging of scale in a drain port.SOLUTION: A steam generator is configured by: a water storage chamber 28 for storing water; a first steam generating heater 50 and a second steam generating heater 51 for generating steam by heating the water in the water storage chamber 28; a water supply pump 41 for sending water through a water supply port 38 and a water supply passage 40 provided in the water storage chamber 28; a drain passage 43 for draining water through a drain port 39 provided at the water storage chamber 28; a steam jetting port 32 for jetting steam generated in the water storage room 28; and a rib 55 which is arranged in the upstream of the drain port 39 and in which an opening 59 smaller than the flow passage of the drain port 39 is formed. With this configuration, scale pieces pass from a gap by unevenness generating when fixing a filter of a separate member for preventing the scale pieces clogging of the drain port 39 by welding and the like, and the situation is prevented where water cannot be drained because of the scale pieces clogging the drain port 39. |
