Steam generator and control method of steam generator

A steam generator comprising:

• a first chamber configured to store water;
• a heater configured to generate steam by heating the water;
• an overheating protector configured to protect the heater from overheating by:
• based on a temperature of the heater reaching a first temperature, cutting power supplied to the heater to protect the heater from overheating;
• a first temperature sensor configured to protect against mis-triggering of the overheating protector by:
• based on the temperature of the heater reaching a second temperature that is lower than the first temperature, cutting the power supplied to the heater for a first time period;
• and
• resuming supply of power to the heater after the first time period;
• and
• a controller electrically connected to the heater and first temperature sensor and configured to control an operation of the steam generator.

A control method of a steam generator, comprising:

• supplying water to a first chamber configured to store water;
• supplying power to a heater configured to generate steam by heating the water;
• performing overheating protection for the heater by:
• based on a temperature of the heater reaching a first temperature, performing the overheating protection for the heater by cutting the power supplied to the heater to protect the heater from overheating;
• protecting against mis-triggering of the overheating protection for the heater by:
• based on the temperature of the heater reaching a second temperature that is lower than the first temperature, cutting the power supplied to the heater for a first time period;
• and
• resuming supplying of the power to the heater after the first time period;
• and
• based on the temperature of the heater reaching the second temperature that is lower than the first temperature, determining a presence of scale buildup.
