Technical field
The utility model relates to water heater control and regulation technical field, particularly relates to a kind of immediately heating water heater that carries out temperature or gear regulation and control heating with controllable silicon.
Background technology
High-power instant electric water heater's extensive use, its operation principle: after power supply energising, by electrons heat components and parts, carry out Fast Heating flowing water, and can control water temperature by circuit, flow velocity, power electromagnet field, but immediately heating water heater shift control is to carry out stepping by relay substantially at present, and each gear is to be arranged in a combination by relay, gear is more, required relay is also just more, but because of its inner space of water heater limited, thereby the gear that has greatly limited immediately heating water heater regulates quantity, power output can not be segmented, immediately heating water heater leaving water temperature be there will be add one grade of heating leaving water temperature overheated, few one grade of large cold phenomenon of heating leaving water temperature, temperature accuracy is inadequate, while is because each relay needs to carry out current switching in shift transformation process, and contact service life comparatively limited (having require service life) of relay, each relay load is unadjustable.In many gears immediately heating water heater industry, this carries out permutation and combination application with regard to a plurality of relays of needs, has greatly improved production cost, and the actuating of relay is often because electric current is large, easily produces spark, the contact of singing, make circuit cisco unity malfunction, and have larger potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of immediately heating water heater that carries out temperature or gear regulation and control heating with controllable silicon, can directly with silicon controlled as switch, regulate the number of turn of transformation, control power output size, thereby accurate adjustment temperature height, meet different temperature points required while taking a shower, SCR control electric current is divided into random shift, realizes the required any temperature spot of human bathing.
For solving the problems of the technologies described above, a kind of immediately heating water heater that carries out temperature or gear regulation and control heating with controllable silicon that the utility model provides, comprise load circuit and control circuit, described load circuit comprises silicon-controlled device and heating tube, described silicon-controlled device and heating tube series connection are in described load circuit, described control circuit comprises control module and the inflow temperature sensor being connected with described control module, leaving water temperature sensor and water flow sensing unit, and described control module is connected with described silicon-controlled device.
Preferably, described control circuit also comprises the display board being connected with described control module, for displays temperature information.
Preferably, described control module is R5F2L357C chip.
Preferably, also comprise bipolar temperature controller with manual reset.
The utility model immediately heating water heater adopts SCR control current technique to compare with existing Control gear structure, gear can be set arbitrarily, realize the Linear Control of electric current, between gear transposing, realize electrodeless linear regulation, gear is excessively steady, does not have contact arc discharge phenomenon, reaches the unlimited gear regulating power of water heater, extended the Acceptable life of product, cost-saving and reduced the usage space of interiors of products.
Accompanying drawing explanation
Fig. 1 is the utility model immediately heating water heater circuit connection diagram.
Main description of reference numerals:
Bipolar temperature controller with manual reset 11 silicon-controlled devices 12
Water flow sensing unit 17 display boards 18.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, for the utility model carries out the immediately heating water heater circuit connection diagram of temperature or gear regulation and control heating with controllable silicon, comprise load circuit and control circuit, described load circuit comprises silicon-controlled device 12 and heating tube 13, described silicon-controlled device 12 and heating tube 13 series connections are in described load circuit, described control circuit comprises control module 14 and the inflow temperature sensor 15 being connected with control module 14, leaving water temperature sensor 16 and water flow sensing unit 17, described power input is provided with bipolar temperature controller with manual reset 11, described control module 14 is connected with described silicon-controlled device 12, be used for controlling described silicon-controlled device 12 trigger currents.Described control circuit also comprises the display board 18 being connected with control module 14, for displays temperature information.Described control module 14 is R5F2L357C chip.
The utility model by the immediately heating water heater operation principle that controllable silicon carries out temperature or gear regulation and control heating is: first by inflow temperature sensor 15 and leaving water temperature sensor 16, corresponding temperature signal detected, and feed back in control module 14, water flow sensing unit 17 detects discharge high low signal and feeds back to control module 14, the break-make of being controlled controllable silicon electric currents by control module 14 is divided into random shift control heating tube 13 with size and heats, to meet the shower demand of leaving water temperature.Also can calculate by the proportioning of feed water flow value and inflow temperature, thereby according to setting leaving water temperature value, the heating power of the inner heating tube of comprehensive regulation, guarantees the constant of leaving water temperature, and regulates and controls targetedly heating power, saves the loss of the energy.
The utility model can be also average stepping, stepping etc. as required according to customer demand respective design, thereby control flexibly every grade of power, effectively realize user's experience requirements, and can Linear Control current system, having avoided different gears to switch the dash current causing, is effectively the service life of having improved parts.The utility model immediately heating water heater adopts SCR control current technique to compare with existing Control gear structure, gear can be set arbitrarily, realize the Linear Control of electric current, between gear transposing, realize electrodeless linear regulation, gear is excessively steady, does not have contact arc discharge phenomenon, reaches the unlimited gear regulating power of water heater, extended the Acceptable life of product, cost-saving and reduced the usage space of interiors of products.
By specific embodiment, the utility model is had been described in detail above, but these not form restriction of the present utility model.In the situation that not departing from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection domain of the present utility model.
