Detailed description of the invention
Common storage-type electric water heater, generally comprises casing, temperature control system, heating system, inlet and outlet system, corrosion protection system and leakage protection system.A kind of counnter attack that the utility model proposes is added with the energy-saving water-storage formula electric heater of heat, is on this basis, and one is increase current inductive switch, judges that whether water heater is in use with this; Two is improve temperature control system, temperature controller in temperature control system after improvement or temperature control plate have collection memory function to current inductive switch signal condition, after current inductive switch signal condition is effective, temperature control system allows to export thermal control signals, heat rear current inductive switch signal effective status to be eliminated, namely reach water heater and in use then allow heating, the object in use then no longer repeatedly do not heated, but under power on or timing heated etc. initiatively needs heating state, temperature control system does not limit by described current inductive switch signal condition.
Therefore, a kind of counnter attack that the utility model proposes is added with the specific embodiments of the energy-saving water-storage formula electric heater of heat, only need introduce the temperature controller in the temperature control system after improvement or temperature control plate, and the embodiment of current inductive switch these two aspects.
The temperature control system of storage-type electric water heater is mainly divided into mechanical temperature-control and electronic temperature control two kinds, and storage-type electric water heater is also divided into mechanical temperature-control storage-type electric water heater and electronic temperature control storage-type electric water heater thus.
Fig. 1 is the temperature control system heating control circuit schematic diagram of standard machinery temperature control storage-type electric water heater, temperature controller wherein has pressure type, double-metal sheet type etc. dissimilar, but its cardinal principle is all utilize the characteristic of expanding with heat and contract with cold different with the thermal coefficient of expansion of different materials of material to realize, therefore it disconnects or closed relevant with water temperature in casing, water temp. heating is high disconnect to setting value stop heating cooling to be low to moderate certain value after closed beginning heat.The water temperature value read from cooling-water temperature sensor also similarly, is compared with setting value by microprocessor unlike the latter by ordinary electronic temperature control storage-type electric water heater, reaches the setting value upper limit and then stops heating then starting heating lower than setting value lower limit.In a word, after common storage-type electric water heater powers on, no matter whether in use, just so repeatedly heat circularly always.
Fig. 2 adopts a kind of counnter attack of the present utility model to be added with the energy-saving temp controller 3 of heat and alternative standard machinery temperature control storage-type electric water heater thermostat schematic diagram thereof.Described energy-saving temp controller 3 is made up of temperature detect switch (TDS), heating control circuit 2 and relay; Heating control circuit 2 connects current inductive switch 1 and temperature detect switch (TDS) two input signals, and its output signal is the thermal control signals for controlling to add electrothermal relay.
Heating control circuit 2, bistable circuit, the forming with door and power supply for combination water influenza inductive switch status signal and temperature detect switch (TDS) signal for the gathering storage of water influenza inductive switch signal condition that mainly comprise current inductive switch signal input circuit (A, B and C are the tie points for being connected current inductive switch sensor), are made up of d type flip flop, the current inductive switch status signal that d type flip flop exports and temperature detect switch (TDS) signal through with Men Xiangyu after signal be just the thermal control signals of relay.Low level when there being water flow current inductive switch to close, d type flip flop set is exported and keeps high level (current inductive switch signal condition is effective), at this moment the thermal control signals state exported with door and temperature detect switch (TDS) state are consistent, and namely the utility model water heater is in use identical with existing electric heater work, after being heated to certain value, temperature detect switch (TDS) disconnects, therefore the low level produced is while making relay disconnect stopping heating, also make d type flip flop reset and export maintenance low level (current inductive switch signal effective status is eliminated), make the thermal control signals state that exports with door and temperature detect switch (TDS) state irrelevant and be forced to remain without thermal control signals, at this moment no matter whether temperature detect switch (TDS) state changes, relay is in off-state all always, reach and no longer repeatedly heat object, until there is water flow to make d type flip flop be set (current inductive switch signal condition is effective), just may heat again.
In Fig. 2, energy-saving temp controller 3 circuit diagram is signal annexation schematic diagram.Wherein bistable circuit function mainly gathers storage of water influenza inductive switch signal condition, other circuit such as rest-set flip-flop can also be adopted to form, also can be that other has the circuit gathering memory function, bistable circuit and also can adopt a slice EPLD with the logic circuit such as door or being built in other ASIC and realize around thereof, for reducing gate circuit, pull-up resistor and diode combinations can be adopted to realize with door.Its power supply of different current inductive switch sensors is also different with output signal type, as passive dry contact, normally opened contact normally-closed contact, voltage signal or current signal, they should have corresponding input circuit and power supply mode, usually prioritizing selection normally-closed contact type current inductive switch and corresponding input circuit is answered, object be convenient between current inductive switch with described temperature control system signal be connected when disconnecting, described water heater still can normal work as common water heater, and just the multiple heating function of described counnter attack lost efficacy; Its signal or high level, low level, pulse, along signal, are acted on set-reset end signal or the clock of trigger, need be determined according to physical circuit.Current inductive switch input circuit, power supply mode and signal thereof in Fig. 2 just for example, are not unalterable to the trigger mode of action, but need to do corresponding change according to dissimilar current inductive switch, bistable circuit etc.The thermal control signals exported with door needs power drive rear drive relay, and relay contact should have protection circuit; Contactor can be adopted as required to substitute relay, and namely described in the utility model, relay comprises contactor; Also controllable silicon can be adopted to substitute relay, for the sake of security, the thermal control signals exported with door is generally re-used as silicon controlled trigger signal after photoelectric coupler isolation, or directly adopts solid-state relay, and namely controllable silicon described in the utility model comprises solid-state relay.Below be all apparent, relevant art is also simple ripe, without the need to example one by one, followingly also to repeat no longer one by one.
Fig. 3 adopts a kind of counnter attack of the present utility model to be added with the energy-saving temp controller 4 of heat and the thermostat schematic diagram of alternative standard machinery temperature control storage-type electric water heater thereof.Compared with described energy-saving temp controller 3, they realize the identical implementation of principle difference, energy-saving temp controller 4 adopts the microprocessor of single-chip microcomputer and so on to substitute bistable circuit etc., current inductive switch signal is connected with microprocessor I/O port with temperature detect switch (TDS) signal, thermal control signals is exported by microprocessor I/O port, microprocessor gathers current inductive switch signal and temperature detect switch (TDS) signal by I/O port, and a state flag bit is set for storage of water influenza inductive switch signal condition, when water flow current inductive switch signal intensity, this flag bit is set to effective status.Water temperature is low to moderate setting value temperature detect switch (TDS) and closes, when microcontroller acquires is to (such as by level or signal along triggered interrupts) during this signal, first inquire about current inductive switches signal condition flag bit (realize current inductive switch status signal and temperature detect switch (TDS) signal " with " the another kind of mode that combines), this flag bit is set to effective status and just allows to export thermal control signals, to power on etc. initiatively need heating state not judge this flag bit state directly exports thermal control signals; Water temperature is heated highly to be disconnected to setting value temperature detect switch (TDS), when microcontroller acquires is to then stopping during this signal exporting thermal control signals, is removed by flag bit effective status simultaneously.
Described temperature detect switch (TDS), the temperature controller adopted with common mechanical temperature-control storage-type electric water heater has same or similar temperature-control performance and temperature control principle, manufactured materials and technique etc., and the contact that difference of them needs to carry heating circuit Current Voltage and described temperature detect switch (TDS) primarily of the contact capacity of described temperature controller only needs caused by carrying switching signal.Most simple and practical scheme is that described temperature detect switch (TDS) directly adopts described temperature controller.Described heating control circuit is little on area volume impact, in order to make described energy-saving temp controller compact conformation minimum on existing water heater structure impact, also be to reduce costs simultaneously, by designing relay and the integration of described temperature detect switch (TDS) especially, such as they share an annular seal space etc., but be now still relay and temperature detect switch (TDS) two parts in logic, do not change the composition of energy-saving temp controller described in the utility model.Also controllable silicon can be adopted to substitute relay.
Fig. 4 is energy-saving temperature-control plate 5 schematic diagram that a kind of counnter attack of the present utility model is added with heat, is mainly used in electronic temperature control storage-type electric water heater.General containing microprocessor in common temperature control plate circuit in the temperature control system of existing electronic temperature control storage-type electric water heater, energy-saving temperature-control plate 5 mainly increases current inductive switch signal input circuit in common temperature control plate circuit, for connecting the microprocessor in current inductive switch and common temperature control plate, current inductive switch signal is directly gathered by the microprocessor in common temperature control plate circuit, and a state flag bit is set for it, current inductive switch signal condition is stored in this flag bit, when the inductive switch action of water flow current, this flag bit is set to effective status.Pass through cooling-water temperature sensor, microcontroller acquires to water temperature value be low to moderate setting value need heating time, inquire about this flag bit first, this flag bit is set to effective status and just can heats, water temperature is heated high while setting value stopping heating, and this flag bit effective status is removed by microprocessor.Under upper electrical heating, timing heated etc. initiatively need heating state, microprocessor does not judge this flag bit state before output thermal control signals, and namely going up electrical heating, timing heated etc. initiatively needs heating not by current inductive switch marker position state limit.Obviously compared with existing common temperature control plate, described energy-saving temperature-control plate 5 pairs of costs and structure influence very micro-.
Fig. 5 is energy-saving temperature-control plate 6 schematic diagram that a kind of counnter attack of the present utility model is added with heat, is the another kind of implementation for electronic temperature control storage-type electric water heater energy-saving temperature-control plate.Existing common temperature control plate circuit base adds heating control circuit 2, heating control circuit 2 is identical with related circuit in Fig. 2 or Fig. 3, what difference was mainly that heating control circuit 2 in Fig. 2 Fig. 3 accepts is temperature detect switch (TDS) signal, and heating control circuit 2 in Fig. 5 accepts is the thermal control signals that existing common temperature control plate circuit exports, also can be that other has the control circuit gathering memory function.Wherein, the relay in Fig. 5 is on former common temperature control plate circuit, is shifted out just for convenience of explanation; Power supply in heating control circuit 2 directly can utilize the power supply on existing common temperature control plate circuit.
The required current inductive switch increased of the utility model, also water flow switch is claimed, whether its effect has current influent stream to go out casing for induction, judge that whether water heater is in use accordingly, under it participates in control, reach water heater and in use then allow heating in use then no longer repeatedly not heat object.As long as the sensor that can produce switching signal under flow action all can be used as described current inductive switch, common are tongue tube and float magnetic induction switch, Hall water flow switch, infrared water flow switch etc., can directly outsourcing also can make by oneself.Different current its switching signal of inductive switch and power supply mode are not quite similar, its input circuit, effect bistable circuit or microprocessor mode and power supply etc., also therefore may with the circuit in embodiment to some extent difference be apparent, these technology be all very ripe simple and clear and without the need to describe in detail.
Current inductive switch can be arranged on any position that can sense water flow in casing or inlet and outlet system.Wherein be arranged on the water inlet of inlet and outlet system or delivery port position to be more reliably more convenient for installation and maintenance, on existing water heater structure almost without impact.During concrete enforcement, usually current inductive switch can be arranged on water inlet, to avoid high temperature on the impact of current inductive switch; User installation behaviour is reduced in order to reduce costs, also can by special, the pressure-reducing valve of current inductive switch with the water outlet being positioned at inlet and outlet system is made of one, at this moment should select and the type current inductive switch of the high temperature of resistance to delivery port or attention can take provision for thermal insulation, in order to increase confidence level, current inductive switch is preferably positioned at external water pipe side after pressure-reducing valve exhaust outlet, namely water outlet be first through vent position again through current inductive switch, less on the impact of current inductive switch when such casing water is added the spilling water after thermal expansion and pressure large exhaust.
Current inductive switch is connected with the signal between temperature control system, usually adopts cable to connect, also can adopt soft PCB, infrared ray even dedicated radio link as required, so these technology are all simple and clear and ripe, without the need to describing in detail.Signals collecting memory circuit in current inductive switch and temperature control system is designed to one etc., these are pro forma change, do not change the essence having signal annexation between current inductive switch described in the utility model and temperature control system.
