According to the anti-scalding water tap, the water temperature can be detected in advance by detecting infrared characteristic emitted by hot water, and the electromagnetic valve is timely closed to prevent overheated water from flowing out of the water tap.
Description
Technical field
The present invention relates to the hot-water heating apparatus field, especially, is a kind of anti-scald water tap that prevents that hot water from overflowing.
Background technique
Water tap is living appliance inseparable in the daily life, and it can be divided into several water taps such as single-plicate, twin and tri-coupling type.In addition, also have dividing of monolever and dual-handle.Single-plicate can connect cold water pipe or hot-water line; Twin can connect cold and hot two pipelines simultaneously, and is multiplex in the bathroom washbasin and there is the kitchen of hot water supply to wash the water tap of nappy; Tri-coupling type can also connect shower nozzle except connecing two pipelines of hot and cold water, be mainly used in the water tap of bathtub.The temperature that the monolever water tap can be regulated hot and cold water by a handle, dual-handle then need regulate cold water pipe respectively and hot-water line is regulated water temperature.
Because the sign of the cold and hot water end (W.E.) of most of water taps is also not obvious; simultaneously; because water temperature also can't be known by range estimation, therefore, the event that when the operation water discharge of water faucet, usually can scald; prevent the generation of this type of event; usually near the water outlet of water tap, the valve with temperature inductor is set together, when water temperature over-high; inductor meeting throttle down; prevent that the people from scalding, still, because inductor is after touching hot water; carry out again the action of throttle down; simultaneously, because the impact of circuit delay and valve response speed is understood some hot water and is crossed valve; flow out tap outlet, and then cause the scald accident.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of anti-scald water tap, the temperature probe of this anti-scald water tap can detect water temperature in advance, and in time throttle down prevents overheated current depotition cock.
The technical solution adopted for the present invention to solve the technical problems is:
This anti-scald water tap comprises the water outlet housing, contains valve body and the operating stem of cold and hot water inlets; described water outlet housing comprises feed-water end and waterexit end; described valve body is arranged on the feed-water end of described water outlet housing; described operating stem connects described valve body and is arranged on the outside of described water outlet housing; near the distolateral overtemperature protection valve body that is provided with of described water outlet, described overtemperature protection valve body comprises water channel and is set in sequence in described water channel interior infrared probe and solenoid valve in the described water outlet housing.
As preferably, be coated with reflecting coating on the described water channel inwall.
As preferably, described water channel contains a bend, and described bend arranges described infrared probe on the wall of described water channel water intake.
As preferably, described water channel comprises a spherical cavity, the fixing central position with described spherical cavity by a pole of described infrared probe.
The invention has the advantages that:
Utilize the reflecting coating in water channel and the water channel to make whole water channel have the effect of similar optical fiber; when hot water one enters described water channel; the infrared rays of hot water itself transfers to infrared probe through water channel; judge the switching of solenoid valve behind the infrared probe thermometric, make whole overtemperature protection valve body can thoroughly stop overheated current depotition cock.
