Further, the method also comprises the following steps:
outputting normal-temperature water: by adjusting the opening of the second valve member 22, filtered water flows into the normal temperature water flow path through the second valve member 22.
When the controller receives the command of outputting the normal temperature water, the booster pump 11 is started to make the filter assembly 1 start to produce water, the controller controls the third valve element 32 to be closed and the fourth valve element 6 to be opened, and the controller controls the second valve element 22 to be opened and adjusted to the maximum aperture, so that the normal temperature water flows out at a larger flow rate, and the normal temperature water flows into the fourth valve element 6 from the second valve element 22 and then flows out from the fourth valve element 6. After the water yield of the normal-temperature water reaches the required water yield, the controller controls the fourth valve member 6 to close, controls the booster pump 11 to stop boosting, and finishes the task of outputting the normal-temperature water.
Specifically, the water outlet control method for the water outlet device provided in this embodiment may be performed according to the following steps when outputting normal temperature water:
step S9: the controller receives a water outlet instruction for outputting normal-temperature water;
step S10: the controller controls the booster pump 11 to be started and the first valve piece and the third valve piece to be closed;
step S11: the controller adjusts the opening degree of the second valve part to the maximum degree and opens the fourth valve part;
step S12: when the water yield of the normal-temperature water reaches the required water yield, the controller receives an instruction of stopping outputting the normal-temperature water;
step S13: the controller controls the booster pump 11 to stop water making, closes the fourth valve and stops outputting normal-temperature water.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
