<p>PURPOSE:To make it unnecessary to keep the water surface in a storage tank on a constant level, by constituting the apparatus in such a manner that a feed water valve is controlled by a thermostat provided in a storage tank, and a hot water sucking port is provided to a float, in a hot water supplying apparatus for an automatic vending machine for cup drinks and the like. CONSTITUTION:The temperature in water in a storage tank is kept constant, by a thermostat 5 which is operated when the temperature in water is raised higher than a predetermined temperature, and by a solenoid operated valve 3 which feeds water into the tank. On the other hand, a hot water feed port 9 is always positioned near the water surface together with a float 8, so that the water in the highest temperature can be taken out from the part near the water surface regardless of the change on water level. With such as arrangement, it is always possible to take out the water in high temperature and the temperature in hot water can be kept constant. That makes it unnecessary to keep the water level constant at all times.</p> |
