Abstract

The utility model discloses a domestic hot pump water heater controller with function of reminding hot water, which belongs to water heater controllers, and comprises a control single chip IC1, a measurement input module, a presskey module, a display module and a clock module, a water temperature sensor for collecting the current water temperature, an evaporator sensor and a discharge temperature sensor, a single chip IC2 connected with the single chip IC1, and four paths of output modules connected with the single chip IC2, wherein the measurement input module, the presskey module, the display module and the clock module are respectively connected with the single chip IC1, the water temperature sensor, the evaporator sensor and the discharge temperature sensor are respectively connected with the measurement input module, and the four paths of output modules comprises a compressor output module, a defrosting output module, a fan output module and an alarm output module. The measurement input module collects the current water temperature through the water temperature sensor, the two single chips regulate the temperature according to the run of the water temperature control compressor and judge whether the temperature condition reminded by the water temperature is met, and the domestic hot pump water heater controller has the beneficial effects that the defects of the regular water pump water heater controller on humanity and intelligence are remedied, thus being capable of reminding a user to use hot water timely, and realizing low carbon consumption and energy conservation.

Description

The household heat pump water heater controller that has the hot water prompting function

Technical field

The utility model relates to a kind of water heater controller, specifically is a kind of household heat pump water heater controller that has the hot water prompting function, is particularly useful for independently setting the control of the household heat pump water heater of heating-up temperature.

Background technology

The controller of heat pump water heater of family expenses all is to possess some simple water heating functions and some other auxiliary control function at present, and the user can independently set heating-up temperature in use as required.Because traditional controller of heat pump water heater can not remind the user to use after water temperature arrives desired temperature, meanwhile, water temperature can progressively be cooled off and heat repeatedly, delay user's normal use, go down for a long time, incrustation scale gathers, and has reduced the service efficiency of Teat pump boiler, has increased unnecessary energy consumption; In addition, whether finish, the user can't leave to do other work fully, has reduced user's time availability in order to wait for and to judge in time that hot water is produced.Can not satisfy requirement to water heater hommization and intelligent aspect.

Summary of the invention

In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of household heat pump water heater controller that has the hot water prompting function, this controller can not only carry out basic controlling such as normal water temperature, defrost and timing, and can the automatically prompting user water temperature reach setting value, can normally use, solve the promptness problem of the subjective water of user.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of household heat pump water heater controller that has the hot water prompting function, comprise single-chip microcomputer IC1, respectively measurement input module, key-press module, display module and the clock module that is connected with single-chip microcomputer IC1; Respectively with cooling-water temperature sensor, evaporator sensor and the exhaust gas temperature sensor of measuring the current water temperature of collection that input module is connected; The single-chip microcomputer IC2 that is connected with single-chip microcomputer IC1, No. four output modules that are connected with single-chip microcomputer IC2.Described No. four output modules are: compressor output module, defrost output module, blower fan output module and alarm output module.

Control principle is: measure input module and gather current water temperature by cooling-water temperature sensor, single-chip microcomputer IC1 and single-chip microcomputer IC2 are according to the start and stop of the water temperature control compressor of measuring, and then the realization adjustment, and judge whether to satisfy the temperature conditions that water temperature is reminded; Come the running of control system simultaneously by the temperature of evaporator sensor and exhaust gas temperature sensor collection correspondence, with the reliability of assurance system realization; Real-time clock module provides the current time so that the decision-making of the period of control for controller; Display module carries out the demonstration of temperature by display devices such as liquid crystal display or charactrons, cooperates key-press module to finish checking of the setting of control parameter, data message simultaneously; The result that the control output module is carried out control decision controls the opening and closing of functions such as compressor, defrost, blower fan, warning respectively, and wherein alarm output module is used to carry out the voice prompt function that water temperature is reminded.

The beneficial effects of the utility model are, can remedy conventional controller of heat pump water heater in hommization, deficiency aspect intelligent, remind the user in time to use hot water, realize low-carbon (LC), purpose of energy saving preferably.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is the control output flow chart of the utility model temperature prompt.

The specific embodiment

As shown in Figure 1, this controller is mainly controlled by two single-chip microcomputer, and input module, key-press module, display module and clock module are measured in single-chip microcomputer IC1 major control; Single-chip microcomputer IC2 controls No. four output modules: compressor output module, defrost output module, blower fan output module and alarm output module; Two chip transmits relevant measurement and control signal by the mode of communication.Cooling-water temperature sensor, evaporator sensor and the exhaust gas temperature sensor that the current water temperature of collection is arranged that are connected with the measurement input module.

As shown in Figure 2, when controller possesses heating condition, can judge in the process of heating automatically whether water temperature has reached the heating interval (desired temperature ± temperature return difference) that the user sets, if reach, controller can be proceeded next bar and judge, whether the duration in this temperature range reaches the stabilization time of hot water preparation, if reach, then controller is exported normal alarm signal; Whether controller continues to judge the duration if water temperature has exceeded (desired temperature+temperature return difference) exceeds the too high prompting time-delay of water temperature, and the words that exceed are then sent rapid voice prompt of frequency or indicator lamp flicker; Simultaneously, if water temperature duration of being lower than (desired temperature-temperature return difference) in when heating reaches hot water produce the time of failure after, controller can send the more low and slow alarm signal of frequency, reminds the user to check that in time controller heats the reason of failure.After above three classes prompting exceeded the prompt time of setting, controller stopped the acousto-optic indication automatically, stops to heat.

Claims

1. a household heat pump water heater controller that has the hot water prompting function is characterized in that: comprise control single chip computer IC1, respectively measurement input module, key-press module, display module and the clock module that is connected with single-chip microcomputer IC1; Respectively with cooling-water temperature sensor, evaporator sensor and the exhaust gas temperature sensor of measuring the current water temperature of collection that input module is connected; The single-chip microcomputer IC2 that is connected with single-chip microcomputer IC1, No. four output modules that are connected with single-chip microcomputer IC2; Described No. four output modules are: compressor output module, defrost output module, blower fan output module and alarm output module.
