Claims

[Scope of Claim for Utility Model Registration] (1) An evaporation tank that is supplied with water from a water supply means and heated by a heating means, a drain valve interposed in the middle of a drain pipe connected to the bottom of the evaporation tank, and the evaporation tank. a plurality of water level detection switches installed at several locations in the vertical direction in a water level detection chamber communicating with the evaporation tank and detecting the water level of the evaporation tank; a controller that controls the operations of the evaporator, and a steam generator comprising: a water level detection chamber side wall serving as a non-heating surface of the evaporator; and a drain port provided at the bottom of the evaporator;
A steam generator characterized in that a scale net is provided to partition the two. (2) The steam generator according to claim 1, wherein the scale net is formed of a heat-generating conductive wire and functions as a heater when energized. (3) The steam generator according to claim 1, wherein the scale net is made of heat-resistant resin or heat-resistant rubber having a large coefficient of thermal expansion. (4) An evaporation tank that is supplied with water from a water supply means and heated by a heating means, a drain valve interposed in the middle of a drain pipe connected to the bottom of the evaporation tank, and a water level detection chamber that communicates with the evaporation tank with a a plurality of water level detection switches installed in several directions and detecting the water level of the evaporation tank; and a controller that controls the operations of the water supply means, heating means, and drain valve, respectively, based on on/off of the water level detection switches. , A film made of heat-resistant resin or heat-resistant rubber having a large coefficient of thermal expansion is formed and adhered to the inner surface of the side wall on the side of the water level detection chamber, which is the non-heating surface of the evaporation tank. A steam generator featuring:
