Abstract
The invention discloses a refrigerator chamber supercooling fault detection system and a refrigerator chamber supercooling fault detection method. The refrigerator chamber supercooling fault detection system is characterized by comprising a temperature sensor unit, a control unit and a display unit, wherein the temperature sensor unit is arranged in a refrigerator chamber and is used for detecting the temperature in the refrigerator chamber, the control unit is used for collecting the temperature, measured by a temperature sensor, of the refrigerator chamber in real time, and transmitting fault signals to the display unit, and the display unit is arranged on the outer surface of a refrigerator and is used for displaying the fault signals. The system and the method provided by the invention can be used for accurately detecting the supercooling fault of the refrigerator chamber, the method is simple, the users can be fast reminded when the supercooling fault occurs, and the problem of cold damage to food caused when the temperature of the refrigerator chamber is much lower than the designed temperature range is effectively avoided.
Description
Technical field
The present invention relates to refrigerator compartment and cross cold fault detection system and detection method.
Background technology
Refrigerator compartment is excessively cold refers to that refrigerator temperature departs from a chamber design temperature scope, as 2～8 ℃ of refrigerator cold-storage compartment temperature scopes of design.Refrigerator in use, if the refrigerator cold-storage mean temperature lower than 0 ℃, can think that refrigerating chamber is excessively cold.Refrigerator compartment occurred that cold fault happened occasionally, once, after breaking down, the user can not find immediately, can cause the foods such as vegetable and fruit to be damaged by frost.General electric control refrigerator is at each indoor temperature sensor that all is provided with, for controlling the temperature of chamber between place.Multi-chamber's direct cooling refrigerator generally coordinates the start-stop of compressor to control temperature by switching solenoid valve; Multi-chamber's wind cooling refrigerator with a single evaporator is to open and close and coordinate the compressor start-stop to control compartment temperature by air door.Once can't switch or closing fault appears in magnetic valve, air door, will cause between correspondence the chamber design temperature on the low side.For refrigerating chamber, temperature can cause vegetable and fruit etc. to be damaged by frost lower than 0 ℃ especially.
Summary of the invention
For solving the existing weak point of above-mentioned prior art, the present invention is existing for controlling the sensor of compartment temperature by electric control refrigerator, the detection system and the detection method thereof that provide a kind of refrigerator compartment to cross cold fault, to detecting in time crossing cold fault and informing the user of refrigerator.
Technical solution problem of the present invention adopts following technical scheme:
The characteristics that refrigerator compartment of the present invention is crossed the cold fault detection system are: described detection system comprises temperature sensor unit, control module and display unit;
Described temperature sensor unit is arranged in refrigerator compartment, for detection of reaching, controls the refrigerator compartment temperature;
Described control module is used for the measured refrigerator compartment temperature of the described temperature sensor of Real-time Collection, and transmits fault-signal to described display unit;
Described display unit is arranged at the fridge exterior face, for showing fault-signal.
The characteristics that refrigerator compartment of the present invention is crossed the cold fault detection system also are: at described control module, be provided with the temperature limit value, when the lasting time lower than described temperature limit value of refrigerator compartment temperature that control module collects is not less than T, control module transmits fault-signal to described display unit;
T is 1～30min.
Described temperature limit value is lower than described chamber break point temperature 1-10 ℃.
The detection method that refrigerator compartment of the present invention is crossed cold fault is to carry out as follows:
A, connection refrigerator power supply, described detection system is started working;
