So that the hydraulic pressure of water tank is higher than the hydraulic pressure of heating device, water in water tank is smoothly flowed into heating device；Its
In, the heating device in hot water inlet pipe road is preferably hot water heating case or boiled water machine, such as stepping-type boiled water machine.
Embodiment two:
For the beneficial effect that the present invention will be described in detail, setting side of the present embodiment to the fluid pipeline of liquid supply apparatus
The function that case and liquid supply apparatus are supported is described in detail.
The present embodiment is illustrated by taking the liquid supply apparatus for supporting two kinds of liquid to export as an example, the liquid supply apparatus point
Indescribably water supply and milk, wherein water inlet line can provide cold water, warm water and hot water.
Specifically, the fluid pipeline in the present embodiment includes water inlet line in embodiment one and into drink pipeline, in order to
Convenient for description, the water storage device in cold water inlet road is set as water tank, and the heating device in hot water inlet pipe road is set as
Heater box (or boiled water machine etc.), as shown in figure 3, Fig. 3 is the piping schematic of liquid supply apparatus provided in this embodiment, water storage
Case provides water source simultaneously for cold water inlet road and hot water inlet pipe road；Storage milk is set as into the drink hutch in drink pipeline
Tank.
Liquid supply apparatus in the present embodiment further includes accumulator tank, is realized by setting accumulator tank to liquid supply apparatus
Cleaning and raffinate recycling.Refering to what is shown in Fig. 3, the transfer tube of accumulator tank is connected to the supply source of third electric pump, the supply source
Side is for liquid faucet side, side specially where container for storing milk.
Specifically, cleaning strategy of the central controller according to setting, opens the first electrical valve and controls the first electric pump just
To rotation, perhaps opens the second electrical valve and the second electric pump of control rotates forward or open the first electrical valve and second
Electrical valve simultaneously controls the first electric pump and the second electric pump and rotates forward, and electricity is pumped into water conduit, and according to the clear of setting
It washes strategy opening third electrical valve and controls third electric pump and rotate backward, the electricity in fluid pipeline transfer tube is pumped into back
It receives in slot.
To rotating forward and counter-rotational paraphrase for electric pump in this present embodiment are as follows: by liquid by liquid supply source pump
When entering to liquid faucet side, the rotation direction of electric pump is set as rotating forward；Liquid is pumped into accumulator tank by liquid faucet side
When side, the rotation direction of electric pump is set as rotating backward.
Cleaning strategy in the present embodiment includes complete machine cleaning and milk pipe cleaning strategy, when needing to clean to complete machine
When, central controller opens the first electrical valve, the second electrical valve and third electrical valve, and controls the first electric pump and second
Electric pump, which rotates forward, controls third electric pump rotates backward, by the water in transfer tube successively via water conduit, milk pipe and milk
The transfer tube of pipeline is pumped into accumulator tank.When needing to clean milk pipe, central controller can open the first electricity
Air valve (or second electrical valve) and third electrical valve, and control the first electric pump (or second electric pump) and rotate forward, it controls
Third electric pump rotates backward, and the water in transfer tube is successively pumped into via the transfer tube of water conduit, milk pipe and milk conduit
Into accumulator tank, the cleaning of milk pipe is realized.Certainly, as shown in figure 3, can be set between cold water inlet road and milk conduit
An alternate transmission pipe is set, and the 5th electrical valve is set on the alternate transmission pipe.When needing to clean milk pipe,
Central controller can open the 5th electrical valve, and control third electric pump rotates backward, the cold water in water tank is pumped into back
It receives in slot, realizes the cleaning to milk pipe.
From figure 3, it can be seen that the liquid supply apparatus in the present embodiment further includes that setting is sharing outside water outlet tube wall
The third temperature sensor of side, third temperature sensor incude the water temperature shared in outlet pipe, and the water temperature that will be sensed in real time
It is transferred to central controller in real time, central controller is rotated backward according to the water temperature control third electric pump received, will not
The water for meeting temperature requirements is pumped into the accumulator tank, until the third temperature sensor senses to water temperature meet expectation
Water temperature closes third electric pump and third electrical valve.
Fig. 4 is the control logic schematic diagram of the accurate cold water out of liquid provided in this embodiment supply setting, with reference to Fig. 4 institute
Show, the central controller controls liquid faucet in the present embodiment goes out cold water, and detailed process is as follows:
S410 judges the working condition of liquid supply apparatus, if at liquid supply apparatus when receiving out cold water instruction
In water outlet or out milk state or be in cleaning state, then follow the steps S421, it is no to then follow the steps S422.
S421 does not execute out cold water instruction, and the reason of do not execute to user feedback.If liquid supply apparatus is currently located
Milk state or be in cleaning state in water outlet or out, then it is just busy to user feedback equipment；If liquid supply apparatus can not be held
Row goes out cold water instruction (instruction that central controller receives imperfect etc. reasons), then instructs and malfunction to user feedback.
S422 opens the first electric pump and the first electrical valve, starts to be pumped into cold water to liquid faucet.
S430 judges whether to complete quantitative-outlet, no to then follow the steps if completion quantitative-outlet, thens follow the steps S440
S422 continues to be pumped into cold water to liquid faucet.
S440 closes the first electric pump and the first electrical valve, suspends to liquid faucet and be pumped into cold water.
S450 judges whether current cup number is last cup, if last cup, thens follow the steps S460, otherwise executes
Step S422.
S460 opens third electric pump and third electrical valve, and controls third electric pump and rotate backward, will be residual in transmission pipeline
The cold electricity stayed is pumped into accumulator tank, terminates cold water output.
As shown in figure 3, the hot water inlet pipe road in Fig. 3 further includes the 4th electrical valve, where the 4th electrical valve
Transfer tube one end is connected to the outlet side of the second electrical valve, and the other end is connected to the outlet side of heater box.
When the hot water inlet pipe road of liquid supply apparatus is not necessarily to supply hot water to outlet pipe, central controller opens the 4th
Electrical valve and control the second electric pump rotate forward, enclosed using the transfer tube between heater box, the second electric pump and the 4th electrical valve
