Describe with reference to the accompanying drawings according to the refrigerating plant for water dispenser of embodiment of the present invention proposition, the refrigerating plant control method for water dispenser and water dispenser.
Fig. 1 is the flow chart of the refrigerating plant control method for water dispenser according to the embodiment of the present invention.Refrigerating plant comprises refrigeration module and water dispenser, and as shown in Figure 1, the refrigerating plant control method for water dispenser comprises the following steps:
S1: control refrigeration module and carry out work to lower the temperature to the water in cold water tank.
S2: when the temperature of the water in cold water tank is down to the 1st preset temperature, controls refrigeration module and quits work in the 1st Preset Time.
That is, first control refrigeration module and carry out work, when the temperature of the normal-temperature water in cold water tank is reduced to the 1st preset temperature, controls refrigerating plant and shut down regular hour, such as the 1st Preset Time.
S3: control refrigeration module and again carry out work to proceed cooling to the water in cold water tank.
S4: when the temperature of the water in cold water tank is down to the n-th preset temperature, controls refrigeration module and quits work in the n-th Preset Time.
Wherein, the n-th preset temperature is not more than the (n-1)th preset temperature, and n is more than or equal to 2 and is less than or equal to the positive integer of N.
S5: judge whether the temperature of the water in cold water tank reaches target temperature, when miss the mark temperature, after n increases by 1, repeated execution of steps S3-S4, wherein, target temperature is N preset temperature.
Specifically, refrigerating plant, after shutdown the 1st Preset Time, restarts refrigerating plant, and continue to control refrigeration module and lower the temperature to the water in cold water tank, when the temperature of the water in cold water tank reaches the 2nd preset temperature, the 2nd Preset Time shut down by refrigerating plant.If the 2nd preset temperature reaches target temperature, then without the need to repeated execution of steps S3-S4, just can complete process of refrigerastion, i.e. N=2, can be called that secondary freezes.
If the 2nd preset temperature miss the mark temperature, after n increases by 1, then repeated execution of steps S3-S4, namely control refrigeration module and again carry out work to proceed cooling to the water in cold water tank, and the temperature of water in cold water tank is when being down to the 3rd preset temperature, controls refrigeration module and quit work in the 3rd Preset Time.If the 3rd preset temperature reaches target temperature, then complete process of refrigerastion, i.e. N=3, can be called that three tier structure is cold.
Thus, repeated execution of steps S3-S4, if the 4th preset temperature reaches target temperature, i.e. N=4, can be called that level Four is freezed.By that analogy, until the temperature of water in cold water tank reaches target temperature, i.e. N preset temperature.

In an embodiment of the invention, when N is 3, refrigerating plant is that three tier structure is cold, and step S1-S2 is first order refrigeration, and step S3-S4 is second level refrigeration, and step S5 is third level refrigeration.
Further, the above-mentioned refrigerating plant control method for water dispenser also comprises, and after user's water intaking, obtains the temperature of the water in cold water tank further: if the temperature of the water in cold water tank is less than the 2nd preset temperature, enter the temperature maintenance stage; If the temperature of the water in cold water tank is more than or equal to the 2nd preset temperature and be less than the 1st preset temperature, only perform third level refrigeration; If the temperature of the water in cold water tank is more than or equal to the 1st preset temperature and is less than preset temperature threshold value, perform second level refrigeration and third level refrigeration successively; If the temperature of the water in cold water tank is more than or equal to preset temperature threshold value, perform first order refrigeration, second level refrigeration and third level refrigeration successively.
Be understandable that, the water yield of fetching water in user's cold water tank is larger, and it is more that the temperature of the water in cold water tank rises.Thus, after user's water intaking, if the temperature of the water in cold water tank is greater than target temperature and be less than the 2nd preset temperature, directly enter the temperature maintenance stage, when the temperature of the water namely in cold water tank is more than or equal to the 2nd preset temperature, controls refrigeration module and again carry out work, and the temperature of water in cold water tank is when being down to target temperature, control refrigeration module quits work, and makes the temperature of the water in cold water tank maintain target temperature, takes cold water at any time with standby user.
If the temperature of the water in cold water tank is greater than the 2nd preset temperature and be less than or equal to the 1st preset temperature, then controls refrigeration module and carry out work, and when the temperature of water in cold water tank is down to target temperature, controls refrigeration module and quit work; Enter the temperature maintenance stage, the temperature controlling the water in cold water tank maintains target temperature, takes cold water at any time with standby user.
If the temperature of the water in cold water tank is greater than the 1st preset temperature and is less than or equal to preset temperature threshold value, then control refrigeration module and carry out work, and the temperature of water in cold water tank is when being down to the 2nd preset temperature, controls refrigeration module and quit work in the 2nd preset temperature; Control refrigeration module and again carry out work, and when the temperature of water in cold water tank is down to target temperature, controls refrigeration module and quit work; Enter the temperature maintenance stage, the temperature controlling the water in cold water tank maintains target temperature, takes cold water at any time with standby user.
If the temperature of the water in cold water tank is more than or equal to preset temperature threshold value, then controls refrigeration module and carry out work, and when the temperature of water in cold water tank is down to the 1st preset temperature, controls refrigeration module and quit work in the 1st preset temperature; Control refrigeration module and again carry out work, and when the temperature of water in cold water tank is down to the 2nd preset temperature, controls refrigeration module and quit work in the 2nd preset temperature; Control refrigeration module and again carry out work, and when the temperature of water in cold water tank is down to target temperature, controls refrigeration module and quit work; Enter the temperature maintenance stage, the temperature controlling the water in cold water tank maintains target temperature, takes cold water at any time with standby user.
In addition, it should be noted that, the time that the 1st Preset Time returns to original state according to refrigeration module by duty to N Preset Time is determined.Preferably, the 1st Preset Time can be all identical to N Preset Time, such as, be all more than or equal to 2 minutes.
