222 states individually opened, blower fan 230 and cold source equipment start, individually to the first storage space air feed so that temperature is beyond pre-
If the article fast cooling of temperature, substantially reduces the influence to other articles, fridge freshness retaining storing effect is improved.In another example
The bulk temperature for determining storing compartment in compartment temperature sensing device is higher than limit value.Now, branch air-supply arrangement can start,
Make to feed to the first air feed mouth 211, feed to the distribution openings 222 of the second air feed mouth 212 and the 3rd air feed mouth 213 while open, to storing
Compartment is integrally freezed, and ensure that the balance of storing compartment internal temperature.
The refrigerator of the present embodiment, infrared sensing device 130 is driven vertically in multiple storages using toothed belt transmission component 300
Moved in object space 140, make infrared sensing device 130 sense the article 150 placed in multiple storage spaces 140 discharge it is infrared
Line, to determine the surface temperature of article 150.So as to be can be achieved using an infrared sensing device 130 to different storage spaces
The temperature of storage article 150 in 140 is sensed, and so that the position of refrigerator endogenous pyrogen and temperature is precisely determined, is easy to root
It is controlled according to the situation of thermal source, optimal storage condition is provided for the food in refrigerator, reduces the nutrition leak of food, and
The hardware cost of sensor is saved, is optimized additionally by the arrangement to infrared sensing device, it is ensured that infrared
The infrared sensing region of sensing device can cover whole storage space so that the thermal source of the indoor all positions of storing is determined,
Avoid being interfered simultaneously.
Further, the refrigerator of the present embodiment is wind cooling refrigerator, using ducting assembly according to the surface temperature of article by
Control ground distributes the cooling flow for coming from low-temperature receiver to multiple storage spaces.So as to targetedly to there is high temperature article
Storage space freezed, avoid to whole storing compartment carry out refrigeration waste electric energy.
So far, although those skilled in the art will appreciate that detailed herein have shown and described multiple showing for the present invention
Example property embodiment, still, still can be direct according to present disclosure without departing from the spirit and scope of the present invention
It is determined that or derive many other variations or modifications for meeting the principle of the invention.Therefore, the scope of the present invention is understood that and recognized
It is set to and covers other all these variations or modifications.
