A steam generator and a method for generating steam, the generator comprising a steam chamber fed with water from a water from a water reservoir for heating by a heating source to generate steam, steam being delivered out through a steam outlet, and waste water being evacuated through a drain, the steam generator comprising a control chamber, in fluid communication with the steam chamber so as that a water level in the control chamber is indicative of a water level in said steam chamber; at least one water level-sensor configured for detecting the water level in the control chamber; and a control unit receiving a signal from the water level-sensor. There is further provided a method of generating steam in a steam chamber receiving Water is fed from the water reservoir simultaneously to the steam chamber and to the control chamber, through a single feeding valve, the feed water being mixed with hot waste water drained from the steam chamber, upstream of a drain pump.

A steam generator has a water container and an upper heating device and a lower heating device, a first temperature detection device covering a temperature detection area including the area covered by the two heating devices, a control device for monitoring and evaluating the first temperature detection device and for controlling the activation state of the two heating devices. A flat first temperature detection device covers the outside of the container, and a second spot-like temperature sensor is located on the water container in a region of an upper border of the upper heating device. Both temperature detection devices are used to activate and deactivate the two heating devices such that at first the lower heating device is activated to start generating steam as fast as possible.

A clothes care apparatus includes a main body including a care room accommodating clothes and a steam generator configured to generate steam to be supplied to the care room. The steam generator includes a case having a first side surface and a second side surface opposite to the first side surface with respect to a center line. A first housing is coupled to the case between the first side surface and the center line, and a second housing is coupled to the case between the second side surface and the center line. A first electrode is supported by the first housing, and a second electrode is supported by the second housing and separated from the first electrode.

Provided is a system, in which a display is mounted to a steam generating device to monitor a driving situation or an erroneous operation situation of the steam generating device through the display. It is possible to monitor an operation situation of a steam generating device through a simple screen configuration in real time at a glance, and enable a user to diversely analyze reasons by various factors when an abnormal operation is generated and cope with the abnormal operation.
