Description
Technical field
The present invention relates to a kind of water tap, especially relate to a kind of water tap of Manual-automatic integrated.
Background technique
At present, the water tap form on market is various, is roughly divided into hand control and automation two kinds, is exactly manually utilize manpower to be opened or closed by tap valve, automatic then be automatically opened or closed valve when responding to.Wherein automatic faucet comprises again induction type and touch etc., these water taps extensively in dining room, airport, hospital, the public place such as hotel use and use at private sites such as families.Existing inductive water tap uses very suitable in public places, because do not need to contact the unlatching that can realize water tap, can effectively eliminate safe and sanitary hidden danger; But this induction type water exit mode is at private sites such as families or cure the larger occasion of the water consumptions such as chamber wash, food factory and chain eatery, or needs the occasion of continuous water, it uses and just seems too dull and not handy.And general touching type water tap adopts the touching type water tap of electrical adjustment structure, the parts of core be touch type electronic circuit board and on control circuit, during use, its touch point tactile that catches can use, and after finishing using, again touches and can close.But the touch sensible element of this kind of touching type water tap is generally arranged in the main body of water tap, and this main body and installation table top are for insulate.But this set method easily because the spray splash of table top or the interference of other factor, causes touch switch, continues to open solenoid valve.
Inductive water tap realizes the switch of solenoid valve by sensor circuit.But if the touch sensible element of water tap outside or infrared induction component wear, can not respond to extraneous trigger message, now, what can have a strong impact on people uses regimen condition, and maintenance procedure is complicated.Simultaneously, this inductive water tap is of a great variety; If installed and used at home, general old man is difficult to be convenient to use, and also needs the using method constantly grasping various inductive water tap, and what therefore can have influence on old man and child uses regimen condition.
Summary of the invention
The object of the invention is to overcome shortcoming of the prior art with not enough, a kind of water tap of Manual-automatic integrated is provided.
The present invention is realized by following technological scheme: a kind of water tap of Manual-automatic integrated, comprises tap main body, water outlet part, hand handle, mechanical switch, touch sensible element, the first action induction element, the second action induction element, control unit and solenoid valve; One end of this water outlet part is connected with tap main body, and the other end is provided with a water outlet; This mechanical switch is arranged on exhalant canal; This hand being arranged on this tap main body, and controls the open and close of this mechanical switch; This solenoid valve is arranged on exhalant canal;
Described control unit comprises a detection judge module, in order to judge the opening state of mechanical switch; When mechanical switch is opened, control unit processes the signal from touch sensible element or action induction element; When mechanical switch is closed, control unit does not process the signal from touch sensible element or action induction element.
Touch signal is sent to control unit by described touch sensible element; When closed electromagnetic valve, the unlatching of this control unit Controlling solenoid valve; When solenoid valve is opened, not to this touch signal process.
The induction zone of described first action element arranges water outlet; When sensing that object enters induction zone, send the first trigger signal to control unit; When closed electromagnetic valve, by the unlatching of this control unit Controlling solenoid valve; When solenoid valve is opened, described control unit is not to this first trigger signal process; When this first action induction element will sense that object departs from induction zone, send the second trigger signal and be sent to control unit, by the closedown of control unit Controlling solenoid valve.
The induction zone of described second action induction element and the induction zone of the first action element isolated; When detecting that object enters the induction zone of the second action element, induced signal is sent to control unit, when closed electromagnetic valve, by the unlatching of this control unit Controlling solenoid valve; When this solenoid valve is opened, by the closedown of this control unit Controlling solenoid valve.
By by mechanical switch, touch-induction-type switch and action induction switch application on a water tap, hand control and automation integration can be realized.Meanwhile, what control this water tap by mechanical switch and solenoid valve goes out water state simultaneously.
As a further improvement on the present invention, described hand handle insulate with tap main body; This touch sensible element is arranged on this hand upper.Touch sensible element while unlatching mechanical switch can be made, start solenoid valve, to make the water outlet water outlet of tap main body simultaneously.
As a further improvement on the present invention, described first action induction element is infrared induction element, and the water outlet that this first action induction element is arranged on water outlet part is peripheral; Described second action element is infrared induction element, and this second sense cell is arranged on the outer side surface of water outlet part.By the first action induction element and the second action induction element are provided separately, can avoid causing signal disturbing.
As a further improvement on the present invention, a timer is also comprised; When mechanical switch open and closed electromagnetic valve time, this control unit receives the signal of touch sensible element, and Controlling solenoid valve is opened and controlled this timer and carries out timing; When the Cumulative time of timer reaches setting value, by signal back control unit, by the closedown of control unit Controlling solenoid valve, this timer automatic clear simultaneously;
When mechanical switch is opened and solenoid valve is opened, when this control unit receives the signal of touch sensible element, control timer resets and reclocking, when the Cumulative time of timer reaches setting value, by signal back control unit, by the closedown of control unit Controlling solenoid valve, this timer automatic clear simultaneously.
During by transmitting the unlatching of the first trigger signal with Controlling solenoid valve at touch sensible element, increase and the effect of timing is carried out to the opening time, prevent the waste of water resources.And after closed electromagnetic valve, reset by timer, timing when ensureing each unlatching is identical.
As a further improvement on the present invention, described control unit receives the first trigger signal of the first infrared induction element under closed electromagnetic valve state, then Controlling solenoid valve is opened, and controls this timer and carry out timing; When the Cumulative time of timer reaches setting value, by signal back control unit, by the closedown of control unit Controlling solenoid valve, this timer automatic clear simultaneously;
When described control unit receives the first trigger signal of infrared induction element under solenoid valve opening state, then do not perform any operation.
By transmit at the first infrared induction element the first trigger signal with the unlatching of Controlling solenoid valve while, increase to the opening time carry out timing effect, avoid causing the waste causing water resources.And after closed electromagnetic valve, reset by timer, timing when ensureing each unlatching is identical.
As a further improvement on the present invention, described second infrared induction element, by when sensing that object enters the induction zone of the second infrared induction element, sends induced signal to control unit; When closed electromagnetic valve, Controlling solenoid valve is opened, and controls this timer simultaneously and carries out timing; When the Cumulative time of timer reaches setting value, by signal back control unit, by the closedown of control unit Controlling solenoid valve, this timer automatic clear simultaneously.
