This device is simulated manual work fully and is joined the milk step, cuts down the consumption of energy, and has reduced use cost, has improved the product price ratio and the market competitiveness.The utility model is through experimental study, this device water distribution temperature error: ± 1 ℃; Water distribution volumetric errors: ± 5ml.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the control procedure according to the optimum implementation automatic distribution water of the utility model.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The baby formula milk powder of implementing according to the preferred plan of the utility model constant temperature water distribution system of weighing automatically is as shown in Figure 1.Constitute by hot water tank, hot water temperature's testing circuit, cold water vessels, cold water temperature testing circuit, magnetic valve, the circuit of weighing, microcontroller, keyboard input circuit and liquid crystal display circuit.When not receiving the water distribution instruction, system is as an electronic balance job.Any object (quality must in the LOAD CELLS range) is placed on (circuit of weighing) on the weighing unit, and its quality all can be presented at (model is LCD1602) on the liquid crystal display.If microcontroller (model is ATmega16) has been received by the order of keyboard input circuit input, has then been got into the water distribution pattern.Hot water tank and cold water vessels are installed in the top of water dispensing apparatus respectively, and hot water temperature's sensor and cold water temperature sensor lay respectively in two containers.Temperature sensor adopts the LM235 chip.Signal conditioning circuit adopts the AD620 chip.LOAD CELLS adopts cantilever beam sensor, range 0-600g.
Utilize said apparatus to carry out the automatic concocting method of the water temperature water yield and be specialized application in allotment milk powder, can obtain allocating the required warm water of milk powder and the water yield to have characteristics such as energy-conservation, easy-to-use, accurate.At first use and press the required water temperature of key assignments and the water yield; Detect hot water and cold water respectively through hot water temperature's sensor and cold water temperature sensor then; Obtain hot water temperature's value and cold water temperature value, send into micro controller module and carry out data, according to specific heat of water and heat Transfer Formula:
Wherein the hot water temperature be T1 (℃), volume is V1 (ml), cold water temperature be T2 (℃), volume is V2 (ml), the water temperature of allotting after the mixing be T (℃), the water yield is V (ml).The density of water is C, and specific heat of water is (Q).
Obtain cold water and hot water volume by formula (1), (2) cancellation C and Q:
Through type (3), formula (4) calculate the water yield of required cold water of water distribution and hot water; The numerical value that the real-time monitoring pressure sensor of while single-chip microcomputer obtains; Provide control signal according to this numerical value single-chip microcomputer; The Kai Heguan of control magnetic valve just can put into cup with the cold water and the hot water of proper ratio, the warm water that is the appointment water temperature water yield that obtains after the mixing.
As shown in Figure 2, the water distribution pattern is divided two kinds, and first kind is to carry out water distribution by water distribution temperature that directly provides and water distribution volume.After microcontroller is received preparation information, detect the water temperature in the container respectively, calculate required hot water and cold water volume according to decreasing water distribution method through hot water temperature's sensor assembly and cold water temperature sensor assembly.Be converted into required hot water and cold water quality then respectively.Microcontroller output control signal is opened cold water water distribution control valve and is emitted cold water, the circuit of the weighing this moment cold water quality of weighing in real time, and when reaching when needing the cold water quality, microcontroller output control signal is closed cold water water distribution control valve.Export control signal simultaneously and open hot water water distribution control valve and emit hot water, this moment the Weighing cell module water distribution quality of weighing in real time, when reaching when needing the water distribution quality, microcontroller output control signal is closed hot water water distribution control valve.The water distribution temperature that directly provides and the water distribution pattern of water distribution volume are promptly accomplished.
Second kind is to carry out water distribution according to the proportionate relationship of the quality of milk powder in the feeding bottle, design temperature and milk powder and water.Under this pattern, after microcontroller was received preparation instruction, through the circuit measuring quality of milk powder of weighing, the milk powder that provides according to formula milk then and the proportionate relationship of water calculated the quality that needs water distribution.After water distribution quality and water distribution temperature had been arranged, following step was identical with first kind of pattern.
