Example (b):

this embodiment provides a refrigerator food reminding device that unfreezes, refer to and draw together the figure, the reminding device that unfreezes locates in the refrigerator, including fixing support 1, jar body 3, detection device, reminding device, communication module and singlechip 7, jar body 3 is located on the fixing support, reminding device, communication module and detection device respectively with the singlechip is connected, fixing support includes base 1 and support 8, the one end of support with fixing support connects, and the other end is fixed jar body 3, singlechip, communication module and reminding device fix on the base.

The detection device is arranged in the tank body and used for detecting whether ice in the tank body is thawed into liquid or not, the single chip microcomputer is used for receiving thawing signals sent by the detection device and sending alarm commands to the reminding device so as to send alarm signals, and meanwhile data interaction is carried out between the single chip microcomputer and a mobile phone client of a user through the communication module.

This reminding device thaws is placed in the refrigerator, fixing support has the supporting role, non-conductive liquid has been placed to jar internal 3, when the refrigerator normally operates, liquid is frozen into solid-state, cause the refrigerator indoor temperature too high when refrigerator outage or system fault, thereby when leading to liquid ice to melt, detection device sends thawing signal and gives the singlechip, the singlechip sends alarm command and gives alarm device, provide the user through alarm device, carry out data interaction through communication module and user's cell-phone simultaneously, make outside user can know whether unfreeze in the refrigerator in real time, in order to prevent eating the food that unfreezes rotten. It should be noted that, when the ice in the tank body is thawed and melted to make the steel ball fall, it indicates that the food in the refrigerator has been thawed at this time, and the steel ball contacts with the spring to generate a corresponding thawing signal.

In this embodiment, specifically, detection device includes steel ball 4, copper axle 5 and spring 6, copper axle 5 is fixed the middle part of the jar body 3, the both ends of copper axle 5 respectively with the top and the bottom of the jar body 3 are connected, 4 strings of steel ball are located on the copper axle 5, the bottom is equipped with the recess in the jar body 3, spring 6 locates in the recess, spring 6 and copper axle respectively through the wire respectively with two pin connections of singlechip 7, steel ball 4 along when copper axle 5 whereabouts with spring 6 contacts to produce the signal of telecommunication that unfreezes and give the singlechip.

When the refrigerator normally works and unfreezing phenomenon does not occur, ice is filled in the tank body, the steel ball string is arranged on the copper shaft, the ice is solid and is blocked, the steel ball is located above the copper shaft, when the ice is unfrozen in the refrigerator, the ice in the tank body is melted into liquid, the steel ball is in contact with the spring after falling down along the copper shaft, the steel ball, the copper shaft, the spring and the single chip microcomputer form a passage of the ball spring trigger, unfrozen electric signals are generated for the single chip microcomputer, the copper shaft is used as a guide rail of the steel ball, the copper shaft with good conductivity is adopted, and unstable work of the ball spring trigger caused by overlarge conductor resistance of other metal shafts can be avoided.

The single chip microcomputer sends an alarm command to the alarm device, and the alarm device sends an alarm signal to remind a user that food in the refrigerator is in a unfreezing state.

In order to enable a user to know the thawing time of food in the refrigerator and judge whether the food is rotten or not, a timing module is arranged in the single chip microcomputer and used for recording the thawing time and sending the thawing time to a user client.

In this embodiment, in order to enable the reminding device to be used repeatedly and automatically, after a refrigerator thawing reminding is performed, the detection device can return to an initial state so as to perform the next monitoring, and the tank body is fixed on the fixed support through the turnover mechanism. The turnover mechanism is a steering engine, the steering engine is fixed on the fixed support, an output shaft of the steering engine is connected with the tank body through a connector, and the steering engine is connected with the single chip microcomputer and overturns the tank body for 180 degrees under the control of the single chip microcomputer. Specifically, after ice is thawed into liquid, the steel ball slides downwards under the action of gravity, then the steel ball is contacted with the spring to generate an electric signal, the electric signal is transmitted to the single chip microcomputer, the single chip microcomputer starts timing the thawing time after receiving the signal, and meanwhile, the steering engine is controlled to move, so that the tank body is turned over, and the turning is performed for enabling the steel ball to return to the initial position relative to the tank body. After the liquid in the tank body freezes again, the single chip microcomputer receives a signal and controls the steering engine again to turn over the tank body. Specifically, a film pressure sensor is arranged on the inner wall of the tank body, the volume of water is increased after the water becomes ice, then the pressure applied to the inner wall of the tank body is increased, when the pressure applied to the pressure sensor reaches a certain value, a signal is sent to the single chip microcomputer, the single chip microcomputer knows that the tank body is frozen again, and the turning is performed at the moment to enable the tank body to return to the initial position, finish the timing state and enter the monitoring state again.

It should be noted that the thin film pressure sensor used in this embodiment may be obtained by directly purchasing the thin film pressure sensor from the market, for example, the model may be FSR402, and the working principle thereof is common general knowledge and will not be described herein again.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
