Specifically, if the first set time does not elapse in the first set time elapsed board step (S911), room temperature water may be continuously supplied from the water tank 9 to the boiler 71 in the room temperature water supply step (S500). Conversely, when the first set time previously set in the first set time elapsed board step (S911) elapses, the first sterilization function execution step (S912) may be performed.

In this case, the extraction sterilization unit 64, the passage sterilization unit 63, the nozzle sterilization unit 65, and the recovery sterilization unit 66, excluding the water bottle sterilization unit 61, may not operate.

That is, in the first sterilization function execution step (S912), after room temperature water is supplied from the water tank 9 to the boiler 71, the water bottle sterilization unit 61 is operated for a predetermined first sterilization time, so that the water bottle body 91 Internal sterilization may proceed.

When it is determined that the first sterilization time has elapsed in the first sterilization time elapsed determination step (S913), the first sterilization function termination step (S914) in which the operation of the water bottle sterilization unit 61 is stopped is performed, and room temperature water heating step (S300) may proceed.
