It to include hot tank, heating element, temperature control subelement, expansion tank and/or normal temperature and pressure water tank.Water in hot tank is from low
Temperature rise is to high temperature, because thermal expansion and cold contraction effect is bound to volume expansion, is also possible to have some bubbles, gas in water or on tank skin
Volume expansion degree after bubble is heated is bigger, in heating process, especially close to boiling point when can also gasify and generate water vapour, cause
Volume further expands.So hot tank has been before heating if filled with water, spilling water and will steam outward during heating
Bubble.To solve this problem, expansion tank is generally all set above hot tank, and is connected to exhaust pipe, is being added to store hot tank
The high-temperature gas that the high-temperature expansion water and release generated in thermal process is emerged, or high-temperature expansion water and high-temperature gas are passed through into row
Tracheae is guided in normal temperature and pressure water tank.For this design, hot water export pipeline must be provided with hot water effluent's valve, because of the water outlet
Valve is always run under severe hot environment, therefore the valve is easy leakage, can also there is following problems.

It asks；
2. increasing manufacture original, the cost of expansion tank itself and matched connecting tube and pneumostome, also promising appearance
The machine case cost receiving expansion tank and increasing；
3. temperature is higher at runtime for expansion tank and matched exhaust pipe, machine can be increased ceaselessly to function of environment heat emission
Energy consumption when device is run.
Swelling water guides normal temperature and pressure water tank scheme into:
1. the coolant-temperature gage in normal temperature and pressure water tank is caused to rise, about 32 DEG C~35 DEG C may be usually risen to, in the industry
It is commonly called as " channeling " phenomenon, feels bad when on the one hand user being caused to take normal-temperature water, on the other hand the temperature range is very suitable for
Bacterial reproduction, therefore using the Drinking fountain room temperature water bacteria of this design scheme exceeded is commonplace phenomenon.
2. " channeling " equally causes energy dissipation.
3. normal temperature and pressure water tank is discharged the air that can all suck equivalent volumes every time, then, the dust that is carried in air,
Bacterium just enters the water in water tank pollution water tank therewith.
It is exactly inside hot tank and exhaust pipe part under normal temperature and pressure water storage tank water level before heating there are one problem
It is filled with water, is on the one hand the volume expansion of water after heating process starts, is deposited in the form of micro-bubble in tank
Gas expansion, after minute bubbles expansion during moving up can and other expanded bubbles congregations become atmosphere
Bubble, air pocket under its buoyancy will continue to move up after entering exhaust pipe, by the water top on bubble to swelling water
Case is pushed up to normal temperature and pressure water tank, this part moved up by bubble be ejected hot tank water be not belonging to thermal expansion generate
Water.This part water of hot tank loss can be supplemented from normal-temperature water water tank by hot tank water inlet pipe automatically, however, this part water
Temperature may be very high, entrained heat is not only to waste, and also exacerbates " channeling " phenomenon.The reason is that this design knot
Bubble in the hot tank of structure can only be discharged by exhaust pipe, and water is had been filled in exhaust pipe, because air slit diameter is typically small,
Bubble cannot pass through the water in exhaust pipe and move up, and the water in exhaust pipe can only be pushed to move up, so as to cause heating
In the process, what exhaust pipe was sprayed to expansion tank or normal temperature and pressure water tank is steam water interface or air-water mixture.
