Filed: 2008-06-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a water server capable of positively determing whether an air purging is needed, allowing a heater to perform a heating operation upon performing an automatic air purging as required and positively avoiding an occurrence of empty burning.  <P>SOLUTION: A self heat generating type thermistor is used as a temperature-water detecting sensor and presence/empty of water can be detected in addition to the sensing of temperature. At first, a detected temperature within a hot water tank is applied and when the temperature is 40°C or more, it is discriminated that water (hot water) is present within the tank to allow a heater to perform a heating operation (YES at S2, S3). When the temperature is below 40°C, the temperature-water detecting sensor is switched over to a water detecting state to discriminate whether water is present because it is vague whether water is present (S5, S6). When water is present, the heater is allowed to perform heating operation (YES at S6) and in turn when water is not present, a hot water intake valve is controlled to open and an air purging is carried out within the hot water tank (S7). Heating at the heater is allowed (S3) upon air purging until the tank is filled with water up to its full-filled state (YES at S8).  <P>COPYRIGHT: (C)2010,JPO&INPIT
