Description
Technical field
The utility model relates to a kind of water heater, specifically a kind of control system of protection against electric shock storage-type electric water heater.
Background technology
Storage-type electric water heater has come into dry family ten thousand family as a kind of common electric, safety problem in its use procedure, also the focus that people pay close attention to just day by day is become, lay special stress on leaks electricity safety problem by storage-type electric water heater new standard, and safety standard, performance standard, installation specification 3 motions enter the review stage.When wherein having a bath, electric leakage is that this safety problem compares distinct issues at present.From electric leakage reason, mainly contain power line electric leakage, heating tube insulating properties are bad, imperfect earth etc.When people open the effluent switch of water heater, just likely cause personal injury.People mainly install electricity-preventing wall device additional for solving electrical leakage problems, but its cost compare is high.Also having a kind of is use the safe voltage of big current to power, but too low voltage heating effect is poor, and needs to arrange transformer, too increases production cost.Because storage-type electric water heater has certain moisture storage capacity, general moisture storage capacity enough users use, and therefore, in use can use by deenergization, this just needs user to pull out attaching plug in use, operates very loaded down with trivial details, trouble like this.If forget operation during use, or can be dangerous.If moreover use after, do not switch on power in time, water heater also can be caused to work, cause next time use time do not have hot water to use.Therefore people also can select to install earth leakage protective device, but earth leakage protective device insufficient sensitivity, that is can not power-off in time in the moment of electric leakage, equally also can cause danger.
Utility model content
The purpose of this utility model is the shortcoming existed to overcome prior art, and provide a kind of structure simple, easy to assembly, production cost is low, and security performance is high, can when user uses hot water the control system of a kind of protection against electric shock storage-type electric water heater of auto power off.
The utility model object realizes with the following methods: a kind of control system of protection against electric shock storage-type electric water heater, it comprises power supply and is located at the heat-generating pipe in water-heater water tank, temperature sensor, it is characterized in that: described heat-generating pipe is connected by relay with between power supply, relay Electricity Federation in the controls, described control system is also connected with the water flow sensing unit be arranged in outlet pipe or water inlet pipe, when water flow sensing unit has detected water flow, after the computing signal of master control borad and control system, disconnect relay immediately, stop powering to heat-generating pipe, when there is no the water-flow signal detected, relay recovery is to the power supply of heat-generating pipe, heat-generating pipe is heated to design temperature to water.
Described master control borad is also connected with infrared sensor, when detecting bathroom and having people, automatically disconnects relay, stop powering to heat-generating pipe.
In the outlet pipe that described water flow sensing unit is connected on water heater or water inlet pipe.
Described water flow sensing unit comprises two ends with the supervisor of pipe joint and the impeller be located in pipe, and impeller is connected in rotating shaft, and being provided with outside rotating shaft can the Hall element of perception axis of rotation.
Described Hall element is outside equipped with attachment plug and master control borad electrically connects.
The beneficial effects of the utility model are: 1) structure is simple, and easy to assembly, production cost is low, improve the market competitiveness.2) when having people to use hot water by water flow sensing unit or the detection perception of infrared sensor, automatically disconnect water heater power supply, ensure that user can not get an electric shock, promote the safety in utilization of water heater.3) whole process Automatic Control, without the need to manual operation, alleviates burden for users, promotes intelligence degree.

Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.A kind of control system of protection against electric shock storage-type electric water heater, it comprises power supply and is located at the heat-generating pipe in water-heater water tank, temperature sensor, it is characterized in that: described heat-generating pipe is connected by relay with between power supply, relay Electricity Federation in the controls, described control system is also connected with the water flow sensing unit 1 be arranged in outlet pipe or water inlet pipe, when water flow sensing unit has detected water flow, after the computing signal of master control borad and control system, disconnect relay immediately, stop powering to heat-generating pipe, when there is no the water-flow signal detected, relay recovery is to the power supply of heat-generating pipe, heat-generating pipe is heated to design temperature to water.
Described master control borad is also connected with infrared sensor, when detecting bathroom and having people, automatically disconnects relay, stop powering to heat-generating pipe.
In the outlet pipe that described water flow sensing unit 1 is connected on water heater or water inlet pipe.
Described water flow sensing unit 1 comprises two ends with the supervisor 3 of pipe joint 2 and the impeller 4 be located in pipe, and impeller 4 is connected in rotating shaft 5, and being provided with outside rotating shaft 5 can the Hall element 6 of perception axis of rotation.
Described Hall element 6 is outside equipped with attachment plug 7 and electrically connects with master control borad.
Operation principle: be provided with the water flow sensing unit with master control borad and control system Electricity Federation in this case in the controls, the power supply of heat-generating pipe is linked in power supply by relay, when user uses hot water, outlet pipe or the water inlet pipe of water heater have water flow, thus promote the wheel rotation of water flow sensing unit, when Hall element detects wheel rotation, produce the signal of telecommunication and feed back to control system, control system cuts off the power supply of heat-generating pipe or whole system immediately, thus avoids the hidden danger of user's electric shock from root.
Except using water flow sensing unit, infrared sensor also can be adopted to detect, (be generally inside, bathroom) when user comes in search coverage, control system can disconnect relay, stop powering to heat-generating pipe, the function of water outlet power-off can be realized equally, ensure user's use safety.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to allow the personage being familiar with this art can understand content of the present utility model and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
