Cold warm pure boiling water frequency conversion water dispenser
Technical field
The present invention relates to a kind of water dispenser.
Background technology
Water dispenser is the electrical equipment often using during people live, can Automatic-heating, can provide hot water at any time, use easily, for many years, although the water dispenser profile style of selling on market is ever-changing, but its inside is all electrothermal tube heating, its course of work is lower than when setting value, to start heating when temperature, water is opened the rear heating that automatically stops, when people emit boiling water, discharge reduction in thermotank, cold water flows in thermotank and is supplemented simultaneously, sneak in boiling water, therefore the weak point of this water dispenser is, the hot water majority that people emit is the hot water that boiling water and unboiled water mix, it is not hjolomorphism boiling water, the unboiled water containing not open in this mixing water, do not pass through high-temperature sterilization, long-term drinking is unfavorable to health, the hot water that contains unboiled water is not suitable for for making tea, and as need are made tea, also will heat up water with traditional instruments such as water heater or pots, very inconvenient.Comprehensively above-mentioned, existing water dispenser weak point is: in boiling water, be mixed with unboiled water, be unfavorable for health, be not suitable for making tea; Delivery port temperature is higher, and the boiling water of directly drinking can not be provided.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of water dispenser of hjolomorphism boiling water, the pure boiling water of cold, warm, hot three kinds of temperature that this water dispenser can directly provide.
In order to solve the problems of the technologies described above, the invention provides a kind of cold warm pure boiling water frequency conversion water dispenser, comprise casing, thermotank, water inlet, hot water outlet, cooling water outlet and heater, it is characterized in that: in casing, be also provided with warm water bucket and cold water bucket, thermotank is communicated with warm water bucket and cold water bucket by sewer pipe, warm water bucket is connected respectively warm water outlet and cooling water outlet with cold water bucket, lower water control valve is housed on sewer pipe, in thermotank, be provided with level sensor and temperature sensor, level sensor is connected controller with temperature sensor, controller can be controlled lower water control valve and heater, heater is in parallel with the circuit of lower water control valve, lower water control valve is normally open solenoid valve, heater comprises frequency converter and induction coil.
Further, be provided with three level sensors of upper, middle and lower and a temperature sensor in described thermotank, described controller adopts the time control of BF-3030 type, temperature control, liquid level integrated controller.
Further, below described thermotank, be provided with successively insulating barrier, induction coil and cooling fan.
Further, described thermotank and warm water bucket are wrapped with insulation material, and thermotank is provided with blast pipe, establishes pressure ball in blast pipe, and warm water bucket and cold water bucket are provided with escape pipe.
Further, described cold water bucket wall peripheral hardware semiconductor chilling plate.
Further, the outlet pipe of described warm water bucket and cold water bucket is provided with out water pump, and warm water outlet and cooling water outlet place are provided with the inductive switch of controlling out water pump.
Further again, described controller connects A.C. contactor, and A.C. contactor is controlled the circuit of lower water control valve and heater.
After the present invention's energising, when in thermotank, water level is lower than the position of lower level sensor, controller is opened water inlet control valve, cold water enters in thermotank from water inlet, water level higher than lower level sensor after, controller opens heater, this at present water control valve close, when water level arrives after the upper limit, controller cuts out water inlet control valve, heater continues heating, until reaching 100 degree boiling Time Controllers, water temperature makes heater stop heating, open lower water control valve simultaneously, hot water enters in warm water bucket and cold water bucket by sewer pipe, water level in thermotank is during lower than the position of lower level sensor, repeat said process, so repeatedly, until warm water bucket, water in cold water bucket and thermotank is full up, and after the boiling of the water in thermotank, water dispenser quits work, now, water inlet control valve is in closed condition, lower water control valve is in open mode, water in water dispenser is all pure boiling water, water temperature in thermotank is reduced to be set after minimum temperature, heater just starts heating, during boiling, stop heating, can guarantee that like this water in hot water barrel is high warm water all the time, water in warm water bucket and cold water bucket can be lowered the temperature gradually and be become warm water, if open the semiconductor chilling plate of cold water bucket wall peripheral hardware, can reduce very soon the water temperature in cold water bucket, make it become low-temperature cold water.
In the time of need to making tea with hot water, from hot water outlet, can emit the boiling water of high temperature; While needing warm water directly to drink, can emit warm water from warm water outlet; When it heat need to be drunk cold water, can be directly from emitting the cold water of low temperature in cold water bucket, very easy to use, and be all the pure boiling water after heating disinfection.
The present invention compared with prior art, advantage is: the pure boiling water that can emit three kinds of different temperatures, the existing high-temperature-hot-water that can make tea, also there is the warm water that can directly drink, the cold water that can relieve summer heat in addition and lower the temperature, these water have all passed through the pure boiling water of heating disinfection, and long-term drinking is conducive to health, reduce the infringement of germ; Thermotank is provided with insulating outward, and heat loss is slow, power and energy saving more, and the present invention can establish large, medium and small type, large-scalely does central boiled water supplying system, as long as load onto bifurcated passage tap, is applicable to school, hospital etc.The medium-sized public place that is applicable to, the small-sized various places that need to use water dispenser such as office, family that are applicable to, this is practical is fully automatic working, need not be manually on duty, as long as plug electricity, connect water inlet pipe, maintain just periodic duty for a long time of cold feed.
