Technical field
The utility model relates to a kind of air-source water heater controller, and specifically a kind of domestic air energy water heater controller is applicable to the control of domestic air energy water heater.
Background technology
In recent years, domestic air can water heater be shown one's talent from pot-type boiler market with its advantage such as energy-conservation, safe, more and more is subject to people's favor.The principle of air-source water heater hot water preparing is different from traditional gas water heater or electric heater; it need to utilize compressor bank to carry out work; for the safety of unit operation, in the process of hot water preparing, also need to carry out defrost, exhaust high temperature protection, system pressure protection etc. according to ruuning situation.Because the above technical characterictic of domestic air energy water heater, present air-source water heater controller on the market is many derives from highly professional generator set controller, except showing, arranging the water temperature, the unit operation parameter that can also show series of complex, and can carry out some manual controls to unit by controller, these functions purposes for common domestic applications is little, too specialty, loaded down with trivial details, the user is difficult for left-hand seat, and produces maloperation easily.
In the concrete application of family expenses air-source water heater, user's occasional needs to use hot water after being expected at special time, the solution of domestic air energy water heater controller is to comprise real time clock circuit in controller inside on the market at present, and one or more groups is provided, and regularly the time period of open and close is arranged by the user, but this method complex operation, As time goes on clocking error can strengthen or occur mistake simultaneously, cause water heater in needs hot water, not work, perhaps misoperation when not needing hot water.
Summary of the invention
In order to overcome above-mentioned domestic air energy water heater controller deficiency in the use, the utility model provides a kind of domestic air energy water heater controller, this controller is when satisfying the control of domestic air energy water heater unit, demonstration and the operation of controller have been simplified, the operation that the domestic consumer is commonly used is assigned to concrete single button, and singly-bound reservation timing function is provided, arrange simple and easy, directly perceived, realistic domestic consumer's operation requirements.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of domestic air energy water heater controller, comprise line control machine and control panel, described control panel comprises the microcontroller II, the sensor acquisition module, relay output module, power module and the communication module that are connected with the MCU II respectively; Described sensor acquisition module comprises cooling-water temperature sensor, evaporator temperature sensor, exhaust gas temperature sensor; Described relay output module comprises the driving relay of controlling compressor, the driving relay of control cross valve and the driving relay of control evaporator fan; Described line control machine comprises the microcontroller I, the key-press module and the display module that are connected with the MCU I respectively; Described key-press module comprises that touching chip I, touch chip II and switch switch, timer reservation key, temperature increase key and temperature reduces four buttons of key; Switch switch, timer reservation key and touch the chip I and is connected gauge tap machine and timer reservation, temperature increase key and are connected key with temperature and are connected the increase of controlling water temperature with touch chip II and reduce; Display module shows current water temperature, cooperates simultaneously button to finish reservation timing, water temperature setting; The microcontroller I is connected by communication module with the microcontroller II.
The specific works process is as follows:
(1) user can water heater start shooting domestic air or shutdown by the soft-touch control switch in use; Disposable automatically the beginning heats after arranging 1～24 hour by the timer reservation key, or the cancellation timer reservation; Increase key by temperature and increase desired temperature; Reduce key by temperature and reduce desired temperature.
(2) display shows user's operation information when the user operates, and shows in real time water temperature behind user's end operation.
(3) duty and the set temperature that arrange according to the user of microcontroller, and the default control parameter of producer carries out the control of unit, obtains current water temperature, evaporator temperature, delivery temperature by measurement module.When reservation regularly or during start, after water temperature is lower than user's design temperature and deducts default control return difference, by the control module drive compression machine hot water preparing of starting working, after reaching user's design temperature, water temperature stops hot water preparing; After evaporator temperature is lower than frosting temperature certain hour, drives the cross valve commutation and defrost; Close compressor when excessive discharge temperature, time-out heats.
The beneficial effects of the utility model are: this controller possess can unit to domestic air normally control function in, kept switching on and shutting down and the temperature that the domestic consumer commonly uses function be set, and increased singly-bound timer reservation function.Touch key-press is easy to operate; Keypress function is succinctly directly perceived, operates simple and easyly, can avoid maloperation; Adopt the singly-bound reservation regularly, operate simple and easyly, also do not have the impact of real-time clock cumulative errors, more realistic domestic consumer's operation requirements.
