A kind of wind cooling refrigerator air door neglected loading provided by the invention detects alarm method, and the method is adopted by temperature sensor
Collect refrigerating chamber real time temperature, according to the difference of real time temperature between refrigerating chamber initial temperature and room as judgement air door installation condition base
Plinth, and marker bit is set, by marking bit value to determine whether neglected loading air door, the aobvious of failure code is carried out by outer display board
Show.
Further, the method specifically includes following steps：
Step 1 starts testing process, closes air door, and when air door closes specific time, record temperature of refrigerating chamber is as initial temperature
Degree；
Step 2 is acquired temperature in refrigerating chamber using temperature sensor interval setting duration, and will be collected every time
Temperature is compared with initial temperature between room, and setting flag position is the air door neglected loading timer when difference is more than given threshold,
And 1 is added to the timer；
Step 3, when temperature is less than given threshold with initial temperature difference between certain primary collected room, judgement air door installation
Normally, timer is reset, and enters conventional commodity inspection Programmable detection refrigerator other parts；
Step 4 judges air door neglected loading, exits detection, carried out by outer display board when the timer is more than given threshold
The display of failure code.
Initial temperature temperature between room of the air door after closing when 2min.
As a preferred embodiment, the threshold value of timer is 120s.
As a preferred embodiment, the decision threshold of temperature and initial temperature difference is -2 DEG C between the room.
A kind of wind cooling refrigerator air door neglected loading detection alarm method provided by the invention is primarily present following advantage：
The present invention acquires refrigerator room temperature by refrigerator in real time, and certain operations judgement is carried out by the temperature to acquisition, to
Make refrigerator that can go out air door neglected loading with automatic decision, and then can alarm on display board plate automatically.Surveyor sees in this way
It is known that be air door neglected loading to alarm code；It the device reduces False Rate, avoids judging by accident, avoids the refrigerator stream of neglected loading air door
To market；Refrigerator commodity inspection percent of pass is improved, efficiency is improved.
Description of the drawings
Fig. 1 is the overall logic schematic diagram of wind cooling refrigerator air door neglected loading detection alarm method of the present invention；
Fig. 2 is wind cooling refrigerator air door neglected loading detection alarm method flow chart of the present invention.
Specific implementation mode
The present invention provides a kind of wind cooling refrigerator air door neglected loading detection warning device, to make the purpose of the present invention, thinking more
Clear, clear, with reference to example, the present invention is described in more detail.It should be appreciated that it is described herein specific implementation only to
It explains the present invention, is not intended to limit the present invention.
A kind of wind cooling refrigerator air door neglected loading provided by the invention detects alarm method, and the method is adopted by temperature sensor
Collect refrigerating chamber real time temperature, according to the difference of real time temperature between refrigerating chamber initial temperature and room as judgement air door installation condition base
Plinth, and marker bit is set, by marking bit value to determine whether neglected loading air door, the aobvious of failure code is carried out by outer display board
Show.
Further, the method specifically includes following steps：
Step 1 starts testing process, closes air door, and when air door closes specific time, record temperature of refrigerating chamber is as initial temperature
Degree；
Step 2 is acquired temperature in refrigerating chamber using temperature sensor interval setting duration, and will be collected every time
Temperature is compared with initial temperature between room, and setting flag position is the air door neglected loading timer when difference is more than given threshold,
And 1 is added to the timer；
Step 3, when temperature is less than given threshold with initial temperature difference between certain primary collected room, judgement air door installation
Normally, timer is reset, and enters conventional commodity inspection Programmable detection refrigerator other parts；
Step 4 judges air door neglected loading, exits detection, carried out by outer display board when the timer is more than given threshold
The display of failure code.
As shown in Figure 1 and Figure 2, a kind of wind cooling refrigerator air door neglected loading provided by the invention detects alarm method according to lower section
Formula is detected：
Into after detection program, first 30 minutes, refrigerating chamber had refrigeration to ask, and air door is opened.30th minute to 45 minutes, refrigerating chamber without
Refrigeration request, air door are closed.It is whether normal that air door is detected by the cooling of a period of time.
If air door installation is normal, enter the conventional commodity inspection stage, if it find that air door neglected loading, then alarm and exit inspection
Ranging sequence.
In air door dwell period, before being closed with air door when 2min, the temperature of refrigerating chamber is initial decision temperature, and starts wind
Door missing inspection decision-making function.First, temperature when air door being closed first 2 minutes in refrigerating box, as initial temperature, and with rule
It fixes time interval, such as 1s, real time temperature between recording room；Judge the difference of real time temperature between initial temperature and room, a wind is set
Door neglected loading timer is more than set temperature per once difference, and the temperature value employed in the present embodiment is -2 DEG C, air door leakage
Dress timer adds 1s；If certain difference is not greater than set temperature, air door neglected loading timer is reset；If air door neglected loading timing
Device value then judges air door neglected loading more than given threshold, exits this commodity inspection, and report an error, which is 120min or smaller.
In above process, it is a variable in this program that air door neglected loading judgement, which enables value, when program goes to air door
Illustrate the decision condition for not meeting air door neglected loading when enabled value is 0 when dwell period, then continues to execute commodity inspection program；When
Enabled value illustrates the decision condition for having reached air door neglected loading when being 1, when can carry out air door neglected loading and determined that i.e. air door is closed
Between have reached 2min.
Commodity inspection program：Commodity inspection 45 minutes in total, first 30 minutes are the door opening stages, need not carry out air door neglected loading inspection
It surveys；15 minutes are air door dwell periods afterwards, need to carry out air door neglected loading detection.So whether determining program is to execute air door pass
It closes the stage, if it is carries out the timing of air door shut-in time；If not then read-me, 30 minutes air doors are opened also before execution
Opening the stage then continues to execute commodity inspection program.
It can be determined that when reaching 120s to air door neglected loading timing continuous integration and alarm for error, if air door neglected loading meter
When continuous integration do not arrive 120s be then likely to be parallel in normal temperature fluctuation, it is believed that do not malfunction, then continue to execute
Remaining commodity inspection program.
There are many this patent concrete application approach, and the foregoing is merely the preferred embodiments of this patent, are not intended to limit
The embodiment and protection domain of this patent are made under the premise of this patent principle to those skilled in the art
With replacing and obviously changing obtained scheme, should all be included in the protection domain of patent.
