Example IV
The present embodiment and embodiment three the difference is that, the hot tank 5 of the water dispenser of the embodiment, hot tank outlet pipe 9, heat
The outer wall of tank water inlet pipe 20 and water fountain effluent pipe 21 is equipped with insulating layer 17, it is preferred that the outer wall and/or heat exchanger of return pipe 13
Outer wall also be provided with insulating layer 17.
Leaving water temperature self-adaptation type water dispenser of the invention is hindered by the way that return pipe is arranged, and by the water flow to return pipe
After power or circling water flow rate are adjusted by proper method, then when water dispenser operates normally, as long as the hot tank of water dispenser is kept
Power supply is connected, and starts the thermostatic control function of hot tank, the leaving water temperature of water dispenser is always able to maintain that in satisfied range, i.e.,
The output water temperature of the water dispenser is close to constant temperature, even if user fetches water, time interval length is that arbitrary value or environment temperature are very low,
The leaving water temperature variation of water dispenser also can be in satisfied range.
Why there is water dispenser of the present invention this length to environment temperature and water intaking time interval to have automatic adjusument
Ability, be because environment temperature is lower, the heat dissipation of outlet valve water inlet pipe is faster, and internal water generates the power of free convection
Bigger, i.e., circular flow is bigger, and the hot water that hot tank is supplemented towards outlet valve water inlet pipe is more, as long as the water inside hot tank
Basic constant temperature is kept, the water temperature inside outlet valve water inlet pipe is also held substantially constant；If environment temperature is higher (such as close
40 DEG C), the heat dissipation of outlet valve water inlet pipe is slower, and internal water generates the power of free convection with regard to smaller, and circular flow is also
Smaller, the hot water that hot tank is supplemented towards outlet valve water inlet pipe is fewer, as long as the water inside hot tank keeps basic constant temperature, outlet valve
Water temperature inside water inlet pipe is equally able to maintain substantially constant.Similarly, user's water intaking time interval is longer, outlet valve water inlet pipe
Heat dissipation capacity is more, and the water temperature in pipe is lower, and the power that internal water generates free convection is bigger, i.e., circular flow is got over
Greatly, the hot water that hot tank is supplemented towards outlet valve water inlet pipe is more, as long as water inside hot tank keeps basic constant temperature, outlet valve into
Water temperature inside water pipe is also held substantially constant；If user fetches water, time interval is very short, it is clear that the width of leaving water temperature decline
It is almost unchanged to spend also seldom or even leaving water temperature.
The free convection principle in thermal conduction study is utilized in leaving water temperature self-adaptation type water dispenser of the invention, merely adds back
Control valve, throttle valve in flow tube and its pipeline do not increase temperature detection and provide the water pump of flow dynamic to circulate,
Also without in addition increase electrical control (using the scheme of gravity-held check valve), required part is few, and system is simple, thus manufacture at
This low and high reliablity, application easy to spread.
The foregoing is merely presently preferred embodiments of the present invention, is merely illustrative for the purpose of the present invention, and not restrictive
