Abstract
The invention discloses a detecting system and a detecting method for faults of refrigerator defrosting system. System hardware comprises a temperature sensor, a control unit and a display unit. The detecting method comprises the following steps that at the moment of starting detection, the continuous connection frequency of a refrigerator defrosting heater and a temperature value of the temperature sensor when the refrigerator defrosting heater is disconnected are recorded, and if the defrosting heater reaches the largest connection frequency, and meanwhile the temperature of the temperature sensor does not reach a set value, a fault signal is sent out. According to the detecting system and the detecting method for faults of the refrigerator defrosting system, software full-automatic recording identification is adopted, and in the use process of a refrigerator, manual detection is unnecessary, so that speed and efficiency are high. Once the automatic defrosting system malfunctions, the faults can be found in advance and a user is notified, and the influence on normal and efficient work of the refrigerator caused by abnormal defrosting of the refrigerator can be avoided.
Description
Technical field:
The present invention relates to a kind of detection system and detection method of defrosting system of refrigerator fault.
Background technology:
In refrigerator use procedure, the situation of defrosting system of refrigerator fault happens occasionally, once after breaking down, refrigeration for refrigerator can not carry out normally and efficiently, and user can not find immediately, causes the waste of electric power energy.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of detection system and the detection method that detect defrosting system of refrigerator fault.By situation of change and the defrosting heater connection number of times of control unit acquisition and recording sensor temperature, and and make comparisons between preset value, judge that defrosting system of refrigerator has fault-free, and the fault message detected is shown by display unit, thus informing user in time, the present invention is particularly useful for the wind cooling refrigerator with intelligent defrosting rule.
Technical solution problem of the present invention adopts following technical scheme:
A detection system for defrosting system of refrigerator fault, described system comprises: the display unit being arranged in the temperature sensor on evaporator of refrigerator, the control unit be connected with described temperature sensor and being connected with described control unit.
Described control unit is a part for the control device of described refrigerator.
Described display unit is a part for the display system of described refrigerator.
Adopt said detecting system to carry out a detection method for defrosting system of refrigerator fault, it comprises the following steps:
When refrigerator enters defrost program, defrosting heater is connected, the temperature of temperature sensor described in shown control unit record, if the described defrosting heater working time reaches default maximum duration, the value of described temperature sensor still lower than the setting value exiting defrost program, then disconnects defrosting heater;
Described defrosting heater is reclosed after waiting for the t1 time, repeat above-mentioned circulation, if defrosting heater connects number of times continuously reach default maximum times, then force to disconnect, control unit sends fault-signal to display unit, and described display unit demonstrates fault message corresponding to described fault-signal.
It is 1-5 time that described defrosting heater presets maximum connection number of times.
The setting value that described temperature sensor exits defrost program is 0 ~ 20 DEG C.
The described t1 time is 8-12min.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Adopt defrosting system of refrigerator fault detection method of the present invention, be particularly useful for the wind cooling refrigerator with intelligent defrosting rule, software is adopted automatically to record identification, control unit machine display unit can adopt original control device and display unit in refrigerator, in refrigerator use procedure, do not need manual detection, speed is fast, and efficiency is high.Once defrosting system of refrigerator breaks down, can find in advance, and point out user, can avoid because of defrosting system fault causes refrigerator refrigeration system can not Effec-tive Function, cause the waste of electric power energy.
Accompanying drawing illustrates:
Fig. 1 is System's composition figure of the present invention; Fig. 2 is the flow chart of detection method.
Below by way of detailed description of the invention, and the invention will be further described by reference to the accompanying drawings.
Detailed description of the invention:
Embodiment: shown in Fig. 1, defrosting system of refrigerator fault detection system of the present invention, its hardware comprises: the display unit being arranged in the temperature sensor on evaporator of refrigerator, the refrigerator control unit be connected with this temperature sensor and being connected with control unit.Control unit can be a part for the original control device of refrigerator, the instantaneous value of temperature sensor when connecting number of times continuously for detection record refrigerator defrosting heater and disconnect, judge whether defrosting system of refrigerator breaks down, then inform user by display unit display.
Adopt said system to carry out the detection method of defrosting system of refrigerator fault, it comprises the following steps:
When refrigerator enters defrost program, open this detection system, defrosting heater is connected and the working time reaches default maximum duration (being generally 60min), the now temperature of control unit record temperature sensor, if the value of temperature sensor still lower than the setting value exiting defrost program, then disconnects defrosting heater;
Defrosting heater is reclosed after waiting for the t1 time (the t1 time is 8min), repeat above-mentioned circulation, if defrosting heater connects number of times continuously reach default maximum times, then force to disconnect, control unit sends fault-signal to display unit, and described display unit demonstrates fault message corresponding to described fault-signal.
In above-mentioned steps, the temperature sensor setting value exiting defrost program can be 0 ~ 20 DEG C, is generally 5-15 DEG C, is generally 8 DEG C according to the optimum setting value of practical experience, it is 1-5 time that defrosting heater disconnects the default maximum times connected again, is for 3 times best based on experience value.Adopt system and method for the present invention, can detect refrigerator ruuning situation in real time for a long time, in refrigerator use procedure, not need manual detection, speed is fast, and efficiency is high.Once defrosting system of refrigerator breaks down, can find in advance, and point out user by display unit, can avoid because of defrosting system fault causes refrigerator refrigeration system can not Effec-tive Function, cause the waste of electric power energy.
