Abstract
A temperature controller comprises a temperature sensor which sends collected temperature signals to a microcontroller, and the microcontroller compares the temperature signals with a preset value and outputs a regulating instruction to an execution circuit after the comparison; and an input end of the microcontroller is connected with a power detection circuit, and an output end of the microcontroller is connected with an alarm circuit. According to the technical scheme, functions of temperature control and power cut alarm are provided. The temperature can be controlled accurately during normal energization, when an outer power supply is off, an inner storage battery is used for supplying power for the microcontroller continuously, a buzzer warns a user, and the temperature is displayed continuously.
Description
Technical field
The utility model relates to a kind of temperature controller that is applied in refrigerator or refrigerator-freezer.
Background technology
Original temperature controller only possesses temperature control function.But when power cut-off, the temperature controller in refrigerator or the refrigerator-freezer does not have any effect on the contrary, causes the temperature control of refrigerator or refrigerator-freezer, thereby causes safety problem.
Summary of the invention
The purpose of the utility model provides a kind of safe temperature controller.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises temperature sensor, and temperature sensor is sent into the temperature signal that collects in the microcontroller, and microcontroller compares temperature signal and preset value, and relatively output regulation and control instruction in back is to executive circuit; The input of said microcontroller connects power sense circuit, and the output of microcontroller connects warning circuit.
Described executive circuit is made up of the relay that is arranged on the machine operation loop.
The output of said microcontroller also is connected with the stand-by power supply start-up circuit.
Adopt the utility model of technique scheme, the function that has temperature control simultaneously and have a power failure and report to the police.During normal power-up, can control temperature exactly, when external power source breaks off, continued to its power supply of control by internal battery, buzzer call is reminded the user, and continues displays temperature.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises temperature sensor, and temperature sensor is sent into the temperature signal that collects in the microcontroller, and microcontroller compares temperature signal and preset value, and relatively output regulation and control instruction in back is to executive circuit; Above-mentioned executive circuit is made up of the relay that is arranged on the machine operation loop.When executive circuit was received regulation and control instruction, the actuating of relay made the machine operation loop works in the state of appointment.
The utility model has warning function when having a power failure for being implemented in, and the input of above-mentioned microcontroller connects power sense circuit, and whether this power sense circuit is exactly having the triggering signal of electricity to send in the microcontroller, the output connection warning circuit of microcontroller.When outage, microcontroller output alarm signal, the buzzer warning in the warning circuit.
In addition, the output of above-mentioned microcontroller also is connected with the stand-by power supply start-up circuit.Above-mentioned stand-by power supply start-up circuit comprises power supply relay, and this power supply relay is arranged in the work loop of reserve battery.Like this, in the time of outage, microcontroller is also exported enabling signal, and subsequent use battery is started working, thereby is that temperature sensor, microcontroller, warning circuit etc. provide power supply.
