The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
It is described in further detail below in conjunction with technical solution of the attached drawing to the utility model embodiment, it is clear that described reality
Applying example is only the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention,
It is practical new to belong to this for those skilled in the art's every other embodiment obtained without creative efforts
The range of type protection.
Embodiment one
As shown in Figure 1, present embodiment provides a kind of blowdown apparatus of water cooler, which includes being equipped with blowdown
Whether the water tank 1 of mouth, the water quality for monitoring water in water tank 1 meet the water quality monitor 2 of preset condition, are used to open or close
The first switch valve 3 of sewage draining exit, for carrying out the moisturizing component of moisturizing to the water tank 1 and being electrically connected to 3 He of first switch valve
The controller 4 of water quality monitor 2.The present embodiment not only realizes the automatic pollution discharge and moisturizing of water cooler, reduce maintenance at
This, has also greatly ensured the normal operation of water cooler, has improved the reliability of water cooler, extended making for water cooler
Use the service life.
Above-mentioned water quality monitor 2 is located at 1 bottom of water tank, real-time monitoring change of water quality, and the water quality monitored includes in water tank 1
PH value, salinity and the total hardness of water, wherein the salinity of water is mainly the concentration of CaCO3 in water cooler water tank 1.Water quality is to cold
The influence of water dispenser group is illustrated by taking total hardness of water as an example, if total hardness of water is too high, fouling is easy on each device, influences cooling-water machine
Group heat exchange, reduces operational efficiency.As long as the pH value, salinity and total hardness in water tank 1 have one to meet the corresponding first default item
Part, then it is assumed that need to carry out water tank 1 blowdown, controller 4 controls first switch valve 3 and opens；It is monitored when water quality monitor 2
The pH value of water quality, salinity and total hardness all meet corresponding second preset condition in water tank 1, then it is assumed that and blowdown terminates,
First switch valve 3 is closed at this time.
Further, above-mentioned first preset condition refers respectively to refer to the pH value of water quality in water tank 1 less than 6.8 or is greater than
9, when total hardness of water is greater than 1100mg/L greater than the concentration of CaCO3 in 500mg/L, water；Second preset condition refers respectively to refer to
The pH value of water quality is more than or equal to 7.0 and is less than or equal to 8.5, total hardness of water less than or equal to CaCO3 in 300mg/L, water in water tank 1
Concentration is less than or equal to 800mg/L.
Controller 4 in the present embodiment is PLC controller or singlechip controller, can be located in water tank 1 by receiving
Water quality monitor 2 water quality that is monitored control being turned on or off for first switch valve 3.
In order to make sewage and the full and uniform mixing of moisturizing, the more water quality accurately in monitoring water tank 1 becomes above-mentioned blowdown apparatus
Change, it is preferable that moisturizing component is located at one end of water tank 1, and sewage draining exit is located at the other end of water tank 1.
Specifically, above-mentioned moisturizing component includes ball-cock assembly 5, and in drainage procedure, water level is lower than 5 water of ball-cock assembly in water tank 1
When the minimum setting value in position, ball-cock assembly 5 can be automatically turned on, and carried out moisturizing to water tank 1, avoided water in water tank 1 from being drained from, lead to cold water
Compressor emergency shutdown.When liquid level reaches 5 water level highest set value of ball-cock assembly, ball-cock assembly 5 can be automatically closed, and be stopped to 1 moisturizing of water tank.
The water cooler realizes the automatic water supplement of water cooler by increased moisturizing component, prevent water in water tank 1 because of blowdown or
Other reasons and cause the water in water tank 1 to be drained from, cause water cooler to be shut down.
Present embodiment also provides a kind of water cooler, the blowdown apparatus including above-mentioned water cooler.The water cooler
Water quality monitor 2 and switch valve are increased, water cooler is realized by the water quality in 2 real-time monitoring water tank 1 of water quality monitor
Automatic pollution discharge, easy to operate, the water in water tank 1 is replaced in time, substantially increases the operational efficiency of water cooler.
Preferably, above-mentioned first switch valve 3 is solenoid valve, solenoid valve is selected not only can to realize the valve when being powered
Automatic opening or closing, can also be operated manually when something goes wrong in solenoid valve.
