Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to specification word to make those skilled in the art.
As shown in Figure 1, the invention provides a kind of water tap assembly, comprising: infrared inductor, the object of its induction near described water tap 2; Solenoid valve, it is arranged on the supply channel of water tap 2; And control module, its communication is connected to described infrared inductor, and when the distance of the object that described infrared inductor senses is less than predetermined inductive distance, control described solenoid valve to open, such as respond in one's hands or clothing, then supply water, when described infrared inductor is when the internal induction of predetermined inductive distance is less than object, control described closed electromagnetic valve namely, in platform dish, there is not hand or clothing to be cleaned etc., then stop supplying water; Wherein, described predetermined inductive distance sets in the following manner: from the beginning timing by off-position converts "on" position to of described control module, described infrared inductor continues the distance of the object sensed as predetermined inductive distance in regular hour section, until described control module gets back to off-position again, eliminate this predetermined inductive distance.
In said process, control module has following two kinds of situations by power-off to the conversion be energized: if just in running order before switch block, such as want changing table dish, then need the power supply of first control module of artificially breaking, make control module be in off-position, after treating that platform basin has been changed, then recover the power supply to control module, make it be converted to "on" position, now control module just can set predetermined inductive distance.If install a new switch block of the present invention on a new platform basin, control module is originally in off-position, and so after installation is complete, direct power-on switch, powers to control module just passable.In assignment procedure, control module should be in "on" position all the time.
When specifically carrying out the setting of predetermined inductive distance, control module is beginning timing by off-position is converted to "on" position, if infrared inductor continues to sense an object in regular hour section, then using the distance of this sensed object as predetermined inductive distance.And when exceeding above-mentioned " time period ", just judge that setting completes, now, then sense object time, just by the distance of this object and predetermined inductive distance versus, and according to the action of comparison result Controlling solenoid valve.Within the above-mentioned time period, should ensure there is no other objects in platform basin as far as possible, and make infrared inductor sense a certain privileged site of platform basin, and using the distance at this position of platform basin as predetermined inductive distance.Fig. 3 shows a kind of water tap, infrared inductor 6 is arranged near the water outlet of faucet body 24, Fig. 4 shows the using state figure that above-mentioned water tap is arranged on a platform basin 5, as shown in Figure 4, infrared inductor senses that above-mentioned " privileged site " can be the darkest position 51, the bottom of platform basin 5, also can be the edge placement of platform basin.The above-mentioned time period can be 8 ~ 10s.
Particularly, in described water tap assembly, the distance of the object that described infrared inductor senses be the infrared-ray launched according to the infrared transmission module of described infrared inductor by control module after reflections off objects, then to be calculated by the time difference after infrared receiving module receives.Fig. 6 illustrates a mode of execution of infrared inductor, and infrared inductor 6 comprises infrared transmission module 20 (infrared transmitting tube), infrared receiving module 22 (infrared receiving tube) and inductor circuit plate 19.
In addition, water tap assembly of the present invention can also make the adjustment of sensitivity according to the difference of service condition.Particularly, at the initial time of described time period, described control module controls described infrared transmission module and first launches infrared-ray with an initial power, after object emission, infrared receiving module receives the infrared-ray by reflections off objects, and output signal, described control module receives this signal, when the level of this signal is 4V, the working power that described control module sets described infrared transmission module is 50% of initial power, when the level of this signal is 2V, the working power that described control module sets described infrared transmission module is initial power, again get back between off-position in finish time to the described control module of described time period, described infrared transmission module launches infrared-ray with working power.Initial power depends on the self-characteristic of the infrared transmission module of infrared inductor, is generally a few milliwatt, such as 0.5mw.
Above-mentioned service condition comprises the irradiance or electromagnetic radiation intensity etc. of the color and luster of platform basin, material, light.Such as, what install is a dark platform basin before, be replaced by a light platform basin afterwards, the infrared-ray that the dark platform basin of strength ratio of the infrared-ray that light color platform basin reflects reflects is poor, the level of this signal that infrared receiving tube can be caused to export to control chip is lower, then now in order to improve sensitivity, need the intensity strengthening the infrared-ray that infrared transmitting tube sends, namely control module setting infrared transmitting tube launches infrared-ray with larger working power, after setting, only power-off again, infrared transmitting tube all sends infrared-ray with above-mentioned working power, otherwise, when replacing a light platform basin with a dark platform basin, because infrared receiving tube can export stronger signal, then can suitable desensitization, set a less working power.In addition, the material of platform basin also has similar impact, and metal material can cause the infrared-ray of reflection comparatively strong, and the level of the signal that infrared receiving tube exports is also strong, and ceramic material then can cause the infrared-ray of reflection more weak.The irradiance of light and electromagnetic radiation intensity also can be same impact.Therefore, in fact, when each control module resets working power, it is all a various factors such as attribute and Environmental Conditions combining platform basin self at that time, just determine a suitable working power, under this working power, infrared receiving tube can receive the infrared-ray of sufficient intensity, and then control module can be made judge accurately, and make solenoid valve action accurately.
