Abstract
The utility model provides a household refrigerator alarm system, it includes temperature measuring module, pressure detection module, the module that resets, ecu, alarm module, ecu links to each other with temperature measuring module, pressure detection module, the module that resets, alarm module respectively, the pressure detection module detects refrigerator door action, and ecu received the signal, took notes temperature at that time, the temperature that detects after a period and initial temperature relatively, when the temperature difference satisfied the setting value, alarm module sent corresponding chimes of doom, the module that resets is auxiliary module, is used for the manual reset system. The utility model discloses simple structure, whether convenient to use is convenient for forget to close or do not close tight and detect to refrigerator freezer door, in time reminds people to close the refrigerator door tight to reduce power consumption.
Description
Technical field
The utility model designs a kind of alarm, particularly relates to a kind of refrigerator warning system.
Background technology
Along with the development of science and technology, household electrical appliance are more and more universal, household electric refrigerator use amount increases gradually, and household electric refrigerator is the work that is energized for a long time, and power consumption is large, if the refrigerating chamber door of refrigerator does not close, or do not close tight, and user does not have Timeliness coverage, larger energy consumption can be caused, and increase the working strength of refrigerator, refrigerator reduction in service life even damages.Existing refrigerator, the overwhelming majority does not have warning system, just in case occur forgetting and close the door, or situation about not closing tight, bring economic loss to user.
Utility model content
The utility model provides a kind of intelligent refrigerator warning system, this system features in convenient, and structure is simple, the advantages such as good stability.
For achieving the above object, the technical scheme adopted is: a kind of household electric refrigerator warning system, it is characterized in that: temperature-measuring module, pressure detecting module, reseting module, electronic control unit, alarm module, described temperature-measuring module, pressure measuring module are embedded in refrigerator refrigeration door edge, the signal detected is sent to electronic control unit by described temperature-measuring module, pressure measuring module, electronic control unit processes surveyed signal, force value reduces and temperature difference meets setting value time output alarm signal report to the police to alarm module.
Above-mentioned household electric refrigerator warning system also comprises reseting module, and described reseting module is connected with electronic control unit, and comprises Independent keys, can hand-reset.
Above-mentioned household electric refrigerator warning system also comprises alarm module, and described alarm module is buzzer.
Above-mentioned household electric refrigerator warning system also comprises electronic control unit, and described electronic control unit comprises A/D modular converter, STM32.
Accompanying drawing explanation
Fig. 1 is system architecture diagram of the present utility model.
Detailed description of the invention
The explanation of detailed description of the invention is carried out: Fig. 1 is system architecture diagram of the present utility model in conjunction with accompanying drawing in description, comprise temperature-measuring module, pressure detecting module, reseting module, electronic control unit, alarm module, described temperature-measuring module measurement module is embedded in refrigerator refrigeration door edge, the signal detected is sent to electronic control unit by temperature-measuring module, electronic control unit processes surveyed signal, and the signal after judging is sent to alarm module.
Described household electric refrigerator warning system also comprises pressure detecting module, described pressure detecting module adopts resistance strain type pressure sensor, quiet dynamically all applicable, and small volume, pressure detecting Module-embedding to refrigerating chamber door edge is used for detecting refrigerating chamber door action.
Described household electric refrigerator warning system also comprises reseting module, and described reseting module is connected with electronic control unit, and comprises Independent keys, can hand-reset.
Described household electric refrigerator warning system also comprises alarm module, and described alarm module is buzzer.
Pressure detecting module is positioned at refrigerating chamber door edge, when opening refrigerating chamber door, the force value detected changes, and is sent to electronic control unit, is controlled by an electronic control unit temperature detecting module, by thermograph now to memory cell, when refrigerating chamber door does not close, or when having a small amount of gap, the temperature that temperature detecting module detects compares with initial value, when temperature difference reaches setting value, with regard to warning reminding user.
