<p>PURPOSE:To keep a discharging nozzle for drink dispenser to be sanitary by providing a temperature sensible semiconductor which is arranged inside a nozzle body made of plastics and a metal ring which is in contact with the temperature sensible semiconductor. CONSTITUTION:In a drink dispenser, an inside of a discharging nozzle and a surface of a tip end of the nozzle become wet after drink is sold or charged by attachment of a small amount of drink syrup, carbonated water, cold water or the like. When alternating or direct current is supplied to terminals 16 and 18 which are connected to a temperature semiconductor 12 of a discharging nozzle, the temperature semiconductor 12 generates heat. The generated heat is transmitted to a metal ring 14 and further led to the discharging nozzle, which is heated as a whole. By this, surfaces of a hole and a tip end of the nozzle, which are wet, are dried up gradually. After drink is sold or charged, the surfaces of the hole and the tip end of the nozzle are heated and dried, so that general bacteria and micro-organisms can hardly propagate by lack of water, whereby the nozzle can be protected from contamination.</p> |
