Abstract
An intelligent water mixer for providing hot water at different temp. is composed of temp. sensor, microcomputerized controller, driver, electromagnetic valves and water-mixing tube. One of hot and cold water tubes is normally opened and another is controlled by the electromagnetic valves with different flows. According to the temp. requirement, an associated electromagnetic valve is opened. The water is mixed in water-mixing tube in which a blade wheel rotating in differntdirection is installed. Its advantages include small occupied space, high accuracy, simple structure, and easy installation.
Description
The present invention relates to a kind of device of fluid-mixing, especially a kind of water admixing device with the solenoid control watering quantity.
Mostly the water admixing device that uses is water tank type, hand or mechanical type at present, owing to need large water tank, it is big to take up room, the consumption material is many, the cost height, and water tank type, hand water-mixing temperature are uncontrollable, it is big that mechanical type water-water jet hot and cold water mixes the back temperature deviation, temperature accuracy is low, and the pipeline installation is loaded down with trivial details, can not satisfy the needs of people aspect mixing hot and cold water.Notification number is the utility model patent of CN2263313Y, a kind of automatic water-mixing formula electric heater is disclosed, in its water admixing device, cold water, hot water line are by solenoid control, and temperature controller is controlled the unlatching of magnetic valve or closed, to regulate the water temperature of water-water jet, this device has tentatively been realized temperature automatically controlled, but still needs to mix water tank, and it is big to take up room, and temperature accuracy is low, and range of application is little.
Purpose of the present invention is exactly that a kind of intelligent water mixer little, simple in structure, that the water-mixing temperature precision is high that takes up room will be provided.
The object of the present invention is achieved like this, intelligent water mixer is made up of temperature sensor, control device, drive unit, magnetic valve and water admixing device, cold water, hot water line feed water admixing device, and temperature sensor places in the water admixing device, and the temperature signal of collection send control device, output control signal after control device is handled, drive magnetic valve and open or close, the control watering quantity is characterized in that: water admixing device is for mixing water pipe, in this pipe, be fixed with the opposite impeller of direction of rotation.
Described cold water or hot water line have one the tunnel to be often to open, the solenoid control of one group of different flow of another route, and control device is a microcomputer controller, according to water-mixing temperature and the size that temperature deviation is set, the magnetic valve of different flow combination is opened in control.
In the described mixed water pipe, be fixed with water trap after impeller, this water trap is the disk of middle perforate, and temperature sensor places after this water trap.
The ratio of the flow of described different flow magnetic valve is 2
n: ...: 8: 4: 2: 1, correspondingly, microcomputer controller is according to water-mixing temperature and the size that temperature deviation is set, and the control signal of output is encoded to 2
n... .8.4.2.1, the magnetic valve of control corresponding discharge.
The intelligent water mixer that adopts technique scheme to make is because without large water tank, it is little to take up room, cost is low, and temperature can artificially be set, water-mixing temperature precision height, constant temperature speed is fast, simple in structure, stable performance, easy for installation, in the use, the size of the output water yield can not cause the fluctuation of output water temperature, can be widely used in shower, hotel, hospital and printing and dyeing industry, is that a kind of desirable constant temperature mixes wetting system.
Fig. 1 is the mechanical operating part structure chart of water-water jet of the present invention.
Fig. 2 is that the present invention mixes the water pipe cut-away view.
Fig. 3 is a microcomputerized control part block diagram of the present invention.
The present invention is further illustrated below in conjunction with accompanying drawing.In the drawings, what sensor was selected for use is temperature sensor, by the corresponding relation of variations in temperature and resistance change,, send microcomputer controller with the resistance value that sensor sample is returned, when water-mixing temperature when temperature being set changing, the temperature value that microcomputer controller is returned to sensor sample with temperature be set compare, the output control signal is sent drive unit, drive magnetic valve and open or close, the control watering quantity.
Generally speaking, cold water pressure is higher than the heat hydraulic pressure, at hot water flow one regularly, controls the incorporation of cold water, can reach the purpose of constant temperature preferably.In supply channel, hot-water line 4 is in normally open, keep certain flow, connect with mixed water pipe remittance 1, in the cold water pipeline, cold water manifold 3 connects by 4 magnetic valves 2 and mixed water pipe remittance 1, cold water, hot water mixes after mixed water pipe remittance 1 enters mixed water pipe 6 in the front portion of mixing water pipe 6, is fixed with two impellers 9 that direction of rotation is opposite, 10, make the hot and cold water that is in laminar condition, through impeller changing backward, reach turbulent condition, fully mix, after impeller, water trap 11 also is housed, water trap is the disk of a middle perforate, and the current after the commutation reach stable state substantially behind water trap, sensor 5 places after the water trap, the water-mixing temperature of can accurately sampling.At the rear portion of mixing water pipe 6, an impeller 12 also is housed, hot and cold water is further mixed after, by pipeline 8 outputs.Mixed water pipe can be one, also can be several, and several so mixed water pipes are used by short tube 7 UNICOMs together, can make the water-mixing temperature precision higher.
For water-mixing temperature is reached as early as possible temperature is set, reduce magnetic valve and open number of times, the flow of 4 magnetic valves 2 in the cold water pipeline carries out layout by the 8.4.2.1 sign indicating number, the ratio of the flow of 4 magnetic valves is 8: 4: 2: 1, correspondingly, the control signal of microcomputer controller output also is the 8.4.2.1 sign indicating number, control the magnetic valve of different flow respectively, temperature sensor send microcomputer controller with the temperature value that records, microcomputer controller to sample temperature with temperature be set compare, according to its temperature difference size, export corresponding 8.4.2.1 sign indicating number, through drive unit, the magnetic valve of control corresponding discharge, vary in size according to the temperature difference, can reach 16 kinds of state of a controls, can be accurate, control watering quantity apace.After the sampling repeatedly of process certain hour, comparison, judgement, the control, the water temperature of output can reach the temperature of setting, and can keep constant temperature like this.The quantity of magnetic valve can increase or reduce, and changes the corresponding output encoder figure place of microcomputer controller and gets final product.
