Wherein, described control button 4 comprises cold water button, hot water button, warm water button and stop button.
Described support front end is provided with insulation indicator lamp and burner on light 3.
Automatic filling control method of the present invention comprises the steps:
(1) state when water surface is X with the distance on cup edge in setting water tumbler is that water tumbler fills;
(2) height of the initial position of setting Fibre Optical Sensor on described slide block at the bottom of apart from cup is H, and the range of described Fibre Optical Sensor is designated as P, meets P>X; The initial position of described Fibre Optical Sensor is greater than P-X apart from the height on cup edge;
(3) water tumbler is placed on to water outlet and takes over bottom, and choosing is by corresponding control button;
(4) existence of ultrasonic sensor sensing drinking cup, and obtain water tumbler altitude information information and deliver to described automatic filling controller, described automatic filling controller is connected corresponding magnetic valve according to user's selection, and the water of water outlet in taking over flows in water tumbler; Described water tumbler height is designated as Y;
(5) distance that the final position that described Fibre Optical Sensor declines is set between the water surface that described Fibre Optical Sensor and water tumbler fill water place is range P, the distance that described automatic filling controller declines according to Fibre Optical Sensor described in the initial position of Fibre Optical Sensor and whole position calculation, and draw the rotating cycle of described stepper motor, drop to final position and put thereby control described slide block and Fibre Optical Sensor.The distance that described Fibre Optical Sensor declines is H-(Y+P-X).
(6) in filling process, described automatic filling controller has judged whether that stop button is pressed and whether water tumbler is withdrawn from, if there is stop button to press, automatic filling controller control respective electrical magnet valve power-off, stops water outlet; If do not have stop button to press, and do not have water tumbler to be withdrawn from, keep respective electrical magnet valve to connect, keep water state; If water tumbler is withdrawn from, automatic filling controller control respective electrical magnet valve power-off, stops water outlet, meanwhile, stepper motor reversion described in the control of automatic filling controller, described Fibre Optical Sensor is got back to initial position.
(7) in the time that the water surface rises to distance cup edge for X place, described in water surface distance, the distance of Fibre Optical Sensor just in time reaches the range P of Fibre Optical Sensor this moment, described Fibre Optical Sensor has echo-signal to return and be received, deliver to described automatic filling controller simultaneously, the power-off of described automatic filling controller control respective electrical magnet valve, water outlet is taken over and is stopped water outlet.
When use, bucket 1 is put on the support 2 of water dispenser.Water enters in hot water preparation plant 15 and heats.
In automatic filling controller, the artificial water surface of setting is X with the specific range on cup edge in advance, thinks that state when the water surface is X with the distance on cup edge is for completely filling state.When user takes drinking water, without the size and the volume that judge water tumbler, only water tumbler is positioned over to water outlet and takes over 5 below, and press cold/heat/warm water button according to the requirement choosing of oneself, the information of selected button sends automatic filling controller to.Described ultrasonic sensor 7 senses the existence of water tumbler and information is delivered to automatic filling controller as occupancy sensor on the one hand, automatic filling controller is only received after control button and two signals of ultrasonic sensor, then is judged according to user-selected button.If what press is hot water button, to control hot water end magnetic valve and open, the hot water in hot water preparation plant 15 enters water outlet by hot-water line 14, hot water end magnetic valve 16 and takes over 5, for water tumbler rushes hot-water flooding.If what press is cold water button, to control cold water end magnetic valve and open, cold water enters water outlet by cold water pipe 19, cold water end magnetic valve 18 and takes over 5, for water tumbler rushes cold water injection.If what press is warm water button, control hot water end magnetic valve 16 and cold water end magnetic valve 18 is opened simultaneously, cold water enters water outlet and takes over 5 after mixing by three-way connection 17 with hot water, be water tumbler punching note warm water.If user only presses control button, water tumbler is not placed on to water outlet adapter place, ultrasonic sensor does not have occupy-place signal to send to automatic filling controller, and automatic filling controller is only received a signal, can not control any one magnetic valve and open, water outlet takes over 5 will can water outlet.Ultrasonic sensor 7 utilizes the range finder module of self to detect the height of water tumbler on the other hand, data message high cup is sent to automatic filling controller after obtaining the high data of cup.
Because described leading screw 10 has definite pitch and step angle, automatic filling controller can be controlled the number of turns that described stepper motor 6 moves, and therefore just can make the Fibre Optical Sensor 8 being connected with the slide block 12 on leading screw can drop to along described leading screw 10 position of needs by automatic filling controller.In the present embodiment, setting measured cup high is Y, the range of described Fibre Optical Sensor is P, described Fibre Optical Sensor 8 is the adjustable range sensors of determining, in the time that the probe of water surface distance Fibre Optical Sensor is greater than P, sensor is transmitted signal only, receive without echo-signal, in the time that the probe of water surface distance Fibre Optical Sensor is less than or equal to P, just having echo-signal returns, and send reception signal to automatic filling controller, therefore when automatic filling controller receives after water tumbler altitude information, can after computing, make described stepper motor 6 rotate and control its number of turn-taking, make described Fibre Optical Sensor 8 drop to water tumbler in the distance of the water surface be the position of range P.Along with continuous water outlet is taken in water outlet, the water surface in cup constantly rises, be X place when the water surface rises to the distance on cup edge, it is the so-called state of filling, now, the distance of the probe of the water surface and Fibre Optical Sensor 8 is just in time the range P of Fibre Optical Sensor, Fibre Optical Sensor 8 will have echo-signal to return and be received, automatic filling controller is received after this signal, make immediately the magnetic valve power-off of having switched on, magnetic valve is in closed condition, water outlet is taken over 5 and is stopped water outlet, after user takes the water tumbler of full dress away because described ultrasonic sensor 7 cannot detect water tumbler occupy-place information, therefore cannot send occupy-place signal and the high signal of cup to automatic filling controller, described in the control of automatic filling controller, stepper motor 6 reverses, described Fibre Optical Sensor 8 is got back to initial position, whole system is in original state.
If in use appearring in water dispenser, user forces to withdraw from the situation of water tumbler, ultrasonic sensor 7 cannot send occupy-place signal and the high signal of cup to automatic filling controller, therefore automatic filling controller makes the magnetic valve power-off of switching at once, water outlet is taken over and is stopped water outlet; If user only needs to access half cup water, can in filling process, people stop key for pressing, by artificial water receiving process forced interruption, system restPoses at once.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
