Dishwasher with heater and method of controlling the same

A method of controlling a dishwasher having a washing chamber, comprising:

• heating air for the washing chamber in a heater positioned outside the washing chamber;
• supplying the heated air to the washing chamber with a blowing fan;
• supplying water into the washing chamber;
• and
• generating hot water through a heat exchange between the heated air and the supplied water,
• wherein the heating of the air for the washing chamber is performed at each of initial stages of washing and rinsing processes, and
• the washing and rinsing processes are each performed using the generated hot water.

A method of controlling a dishwasher having a washing chamber and an air generator that provides hot air into the washing chamber, the air generator having a heater and a blowing fan, comprising:

• starting supplying of water into the washing chamber;
• operating the air generator, the hot air from the air generator heating the supplied water in the washing chamber;
• stopping the supplying of water and operating the air generator if a preset variable corresponding to a property of the washing chamber exceeds a first value;
• and
• starting the supplying of water if the preset variable of the washing chamber exceeds a second value.

A method of controlling a dishwasher having a washing chamber, comprising:

• heating air for the washing chamber in a heater positioned outside the washing chamber;
• supplying the heated air to the washing chamber with a blowing fan;
• supplying water into the washing chamber;
• generating hot water through a heat exchange between the heated air and the supplied water;
• and
• performing a main washing process comprising:
• if a temperature of the air in the washing chamber is increased by a predetermined amount, periodically supplying the water into the washing chamber and then heating the water by the heated air,
• determining whether a water level of the water reaches a preset water level;
• if the water level of the washing water reaches the preset water level, stopping the supplying of the water, while continuously heating and circulating the air in the washing chamber,
• if a temperature of the water reaches a preset temperature, stopping the heating and circulating of the air and circulating the water supplied, and
• if a preset washing time elapses, stopping the main washing process.
