Product.Fig. 6 is the schematic diagram of the overheating prompt method of refrigerating device according to an embodiment of the invention, refrigerating dress
The overheating prompt method set may comprise steps of:
Step S602 detects the unlatching event of the door body 500 of refrigerating device 10；
Step S604, determine door body 500 open after, detect 10 position of refrigerating device environment temperature and
Temperature Distribution in the 400 front setting regions of cabinet of refrigerating device 10；
Temperature Distribution is compared with environment temperature, determines to be placed into the object of refrigerating device 10 by step S606
The temperature of product；
Step S608, judges whether the temperature of article is higher by and the matched temperature threshold of environment temperature；
Step S610, if so, the first article overheating prompt signal of output.
It wherein to be placed into the temperature of the article of refrigerating device 10, can obtain in the following manner: from Temperature Distribution
In find out temperature and region that environment temperature has differences, and using the maximum temperature in region as the temperature of article.Before cabinet 400
Portion's setting regions can be the space in 410 front preset distance of storage room.To be placed into the article of refrigerating device 10
A kind of interchangeable detection mode of temperature be that will test the temperature of the mobile target of range to be used as to be placed into the storage room 410
Article temperature.
Step S608 can determine matched temperature threshold according to environment temperature first, then by the temperature of article with
The temperature threshold matched is compared, and in the case where article temperature is greater than temperature threshold, determines that article overheats.Wherein basis
Environment temperature determines that the step of matched temperature threshold can be with are as follows: judges whether environment temperature is higher than the first preset temperature；
In the case where environment temperature is higher than the first preset temperature, temperature threshold is the sum of environment temperature and the second preset temperature；And
In the case where environment temperature is less than or equal to the first preset temperature, temperature threshold is the first preset temperature.Judge the temperature used
Degree threshold value is matched with environment temperature, so as to avoid judging by accident using fixed temperature threshold bring, such as in environment temperature
When excessively high, the article of room temperature is mistaken for overheat article, or at low ambient temperatures, environment temperature will be apparently higher than
The overheat article of degree regards as room temperature article.
In addition, user is usually to pick and place article with hand, temperature threshold needs to exclude user's hand temperature interference, therefore one
In a little alternative embodiments, above-mentioned first preset temperature is obtained according to the temperature statistics to human hands, the skin surface temperature of human body
Degree is generally below normal body temperature, and the skin temperature of parts of body differs greatly.The temperature of hand is generally 30 DEG C, in addition to by other than
Outside portion's environmental stimulus, the temperature of hand is generally at 30 DEG C or so.Therefore above-mentioned first preset temperature can be set to 30 DEG C.Second is pre-
If temperature can prevent from judging by accident for a constant as allowance is judged, value range can be 2 to 5 DEG C, generally can be set
It is 3 DEG C or 5 DEG C, so as in the case where environment temperature is more than 30 DEG C, if the article temperature detected is more than environment
Temperature reaches 3 DEG C or 5 DEG C, that is, thinks that article overheats.In the case where environment temperature is lower than 30 DEG C, if the article detected
Temperature is more than the temperature of user's hand, that is, thinks that article overheats.
First article overheating prompt signal can non-buzzer issue the alarm light of buzzing alarm and/or alarm lamp, separately
Outer first article overheating prompt signal can also be exported using modes such as display screen display reminding image, voice promptings.
It can also include: the close event for detecting the door body 500 of refrigerating device 10 after step S610；In determination
After door body 500 is closed, the Temperature Distribution inside refrigerating device 10 is detected, to determine the temperature for the article being newly put into；Judgement
Whether the temperature for the article being newly put into exceeds temperature threshold, if so, the second article overheating prompt signal of output.Meeting following appoint
Stop exporting the second article overheating prompt signal in the case where one of meaning condition: the temperature for the article being newly put into drops to temperature
Spend threshold value or less；The article being newly put into is removed；The time for persistently exporting the second article overheating prompt signal is more than preset time
Threshold value；And get externally input stopping prompt command.
Temperature Distribution inside refrigerating device 10 avoids the interference of user's hand temperature, and the article temperature of detection is more
It is accurate to add, so as to persistently be prompted.Second article overheating prompt signal can export article by the way of alarm lamp
Overheating prompt signal, since during user is put into article, the first article overheating prompt signal had carried out alarm, because
This second overheating prompt signal can carry out overheating prompt by the way of minimizing to user's interference.
Overheat judgement is carried out, three factors are primarily present: to be placed into the temperature T3 of article, picking and placing user's hand temperature of article
It spends T4 (about 30 DEG C), the temperature T2 of 10 place environment of refrigerating device.
In above three factor, the temperature T3 to be placed into article be carry out detection main object, however due to hand with to
It is put into article directly to contact, the first article temperature detector 120 can also detect while temperature of the detection to be placed into article
The temperature of hand, and the temperature of hand other than individual external actions the case where (such as just with cold water or hot water being washed one's hands), the temperature of hand
Degree is substantially stable.
General refrigerating device can just be put into storage room 410 after needing for article to be placed into room temperature (room temperature), because
This under normal circumstances, the temperature for being placed in the article in environment for a long time should be identical as environment temperature.And it was actually using
Cheng Zhong when high temperature food places cooling, have to must wait until that temperature is consistent with environment temperature, not necessarily to be placed into the temperature of article
It can permit and be suitably slightly above environment temperature.Therefore temperature threshold can be set above to environment temperature, such as T1=T2+n,
T1 is temperature threshold, and n is the second preset temperature, and value range can be 2 to 5 DEG C, generally can be set to 3 DEG C or 5 DEG C.
Therefore, when environment temperature and to be placed into the temperature of article it is all lower when, to prevent refrigerating device 10 to temperature
Higher hand false alarm；When environment temperature it is higher (torrid areas, summer high-temperature, winter heating environment in), one should prevent
To environment temperature false alarm when enabling, also to guarantee to be more than a certain range of article Normal Alarm of environment temperature to temperature.
Based on the above principles, the principle of excess temperature prompt is carried out are as follows:
At low ambient temperatures, the heat removal capacity of refrigerating device 10 is good, and the heat of article will not disappear
Consuming excessive electric energy and time will be lowered, but for high temperature article, preferably also be placed into the range of environment temperature again
It is put into storage room 410, therefore when the temperature of article is higher than the temperature of hand, i.e. sending standby signal.
When instant food temperature is high, even if slightly above hand temperature, also will call the police；
In the higher situation of environment temperature, the heat removal capacity of refrigerating device 10 is deteriorated, and high temperature article is also not easy to put
Set environment temperature, therefore can when that is, article temperature is less than or equal to T2+n detecting that article temperature is slightly above environment temperature
To be much higher than environment temperature in article temperature, i.e., when article temperature is greater than T2+n, carry out overheat warning without overheat warning.
Since hand can be sensed simultaneously when detecting article temperature, and its temperature is basicly stable, therefore can be according to hand
Temperature setting temperature threshold.
Environment temperature, the temperature of hand, article temperature can all be sensed by infrared temperature sensing device simultaneously, and infrared temperature sensing device can be with
Only the maximum temperature sensed is handled, i.e. T=max { T2, T4, T3 }.
As T2≤T4, the temperature T4 of hand is higher than environment temperature T2, only judges T4 and article temperature T3, if T3≤
T4 only senses temperature in one's hands, i.e. T=T4, prompts without excess temperature；Work as T3 > T4, only sense article temperature, i.e. T=T3, carries out
Excess temperature prompt；
As T2 > T4, environment temperature T2 is higher than the temperature T4 of hand, then only judges environment temperature T2 and article temperature T3,
If working as T3≤T2, environment temperature, i.e. T=T2 are only sensed, is prompted without excess temperature；In the case where T3 > T2, only sense
Article temperature, i.e. T=T3 prompt if T≤T2+n without excess temperature, and T1 > T2+n carries out excess temperature prompt；
To the infrared temperature probe sensing and judgement mark of 400 front temperature-sensitive of cabinet verification 410 inside temperature-sensitive of storage room
