Abstract
The invention discloses a refrigerator fault detection system and detection method. The refrigerator fault detection system comprises a temperature sensor at the position of an inlet of an evaporator of a refrigerator, a control unit connected with the temperature sensor and a display unit connected with the control unit. The refrigerator fault detection method includes the steps of opening a compressor of the refrigerator, meanwhile, enabling the control unit to start to record the initial temperature value of the temperature sensor, continuously detecting the temperature value of the temperature sensor in the limited time of 2-30min, comparing the temperature value with the initial temperature value, and if the drop-out value of the temperature of the temperature sensor is smaller than the preset value of 2-6 DEG C, enabling the control unit to send out fault signals, and enabling the display unit to display the fault signals. According to the refrigerator fault detection system, software is adopted to conduct recording and recognition in a full-automatic mode, in the use process of the refrigerator, manual detection is not required, the speed is high, the efficiency is high, the cost is low, and the misjudgment rate is basically zero.
Description
Technical field:
The present invention relates to a kind of fault detection system and detection method of refrigerator.
Background technology:
In the refrigerator use procedure, refrigerator occurs that the failure condition that does not freeze is more, in case after breaking down, the user can not find immediately, causes food spoilage serious, thereby causes customer complaint, affects product quality and brand image.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of refrigerator do not freeze detection system and detection method of fault of detecting, situation of change by control module acquisition and recording sensor temperature, and the relation between comparison changing value and preset value, the judgement refrigerator has fault-free, and detected fault message is shown by display unit, thereby in time inform the user.
Technical solution problem of the present invention adopts following technical scheme:
A kind of fault detection system of refrigerator, it comprises:
The display unit of being located at the temperature sensor of evaporator of refrigerator porch, the control module that is connected with described temperature sensor and being connected with described control module.
Described control module is located in the control device of refrigerator; Described display unit is located in the display unit of refrigerator.
Adopt this fault detection system to carry out the detection method of breakdown of refrigerator, comprise the following steps:
When freezer compressor was opened, described control module started to record the initial temperature value of described temperature sensor, in limiting time (2-30min), continued to detect described sensor temperature value, and compared with described initial temperature value;
In described limiting time, if described sensor temperature drop-out value less than preset value, control module sends fault-signal and shows through described display unit.Described preset value is 2-6 ℃.
In described limiting time, if the sensor temperature drop-out value more than or equal to preset value, detection of end; After limiting time, judge described freezer compressor continuous operating time, if continuous operating time reaches setting value, and sensor temperature sends fault-signal higher than limit value.
Described compressor continuous operating time setting value is 5-10 hour.The limit value of described sensor temperature is-15--20 ℃.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Breakdown of refrigerator detection system of the present invention, adopt software automatically to record identification, in the refrigerator use procedure, do not need manual detection, and speed is fast, and efficiency is high, and cost is little, and False Rate is zero substantially.In case fault appears not freezing in refrigerator, can find in advance, and the prompting user, can avoid the too high rear user of refrigerator temperature rise could find the fault of not freezing, cause the problem of food spoilage, thereby guaranteed the quality of product.
The accompanying drawing explanation:
Fig. 1 is the fault detection system figure of refrigerator of the present invention; Fig. 2 is the flow chart of detection method.
Below pass through the specific embodiment, and the invention will be further described by reference to the accompanying drawings.
The specific embodiment:
As Fig. 1, breakdown of refrigerator detection system of the present invention, system hardware comprises the temperature sensor of being located at the evaporator of refrigerator porch, the control module that is connected with described temperature sensor and the display unit that is connected with described control module.According to control module collecting temperature sensor values, compare, judge that whether refrigerator breaks down, and then shows and informs the user by display unit.
Referring to Fig. 2, according to detection system of the present invention, carry out the detection method of breakdown of refrigerator: step S110, detect the sensor temperature of refrigerator, refrigerator powers on and when compressor is opened, starts to detect, the sensor initial temperature value T0 of control module detection record refrigerator.Step S120 and S130: in limiting time 2-30min, continue real time detecting sensor temperature value Ti, and with initial value T0 relatively, if the sensor temperature drop-out value less than preset value, control module sends fault-signal and shows through display unit.Preset value is empirical value, is made as 2-6 ℃.Be understandable that above-mentioned preset temperature value only is in the purpose of example, the embodiment of the present invention is not limited to this, should set according to actual conditions.
Step S140: in limiting time, as the sensor temperature drop-out value in limiting time 2-30min more than or equal to preset value, detection of end; After limiting time, judgement freezer compressor continuous operating time, as continuous operating time, reach setting value 5-10 hour, and sensor temperature sends fault-signal higher than limit value-15--20 ℃.In an embodiment of the present invention, preset temperature value only is in the purpose of example, and the embodiment of the present invention is not limited to this, should set according to actual conditions.
