High cooling efficiency.Also, in the present embodiment, by between outlet 30d and cold air return port 39 fabricated food detect
Sensor 48 can accurately detect the case where placed warm food in the rapid cooling section, can automatically start
Rapid freezing.Also, if configuring aluminium pallet in rapid cooling section, recognizable user's energy is that rapid cooling is used
Space.
In addition, tight downsides of the second cold duct 11b due to the shelf 34b near the intermediate altitude positioned at refrigerating chamber 2
Outlet 30c is also set up, the space (the region 2E in Fig. 3) between shelf 34c and shelf 34d can be made also to become rapid cooling
Section.Here, food inspection sensor 48 is located at the tight downside of shelf 34c, even if the spatially placement food on partition board 34c
In the case of also can detect.In addition, due in the 2E of region there is no the component of partition will be controlled, also can will be compared to
The region of the tight upside of the big space of region 2C width, i.e. left side shelf 34d is as rapid cooling object.
Here, the control about the automatic rapid cooling carried out by food inspection sensor 48, uses Figure 15 and Figure 16
It illustrates.First, it is determined that whether the setting of automatic rapid cooling pattern connects (step S1).In automatic rapid cooling pattern
When being set as the state connected, in step s 2 to for determining whether in the case of the on-off action of progress door 2a, 2b
The monitored state of rapid cooling shifts.In step s3, after being shifted to monitored state, food inspection sensor 48 will be anxious
Quickly cooling but allows in the case of judging that the state of critical value or more maintains Time constant (rapid cooling starts to judge the time), is considered as
In the lower part input food of refrigerating chamber 2, start rapid cooling.Here, rapid cooling allows to judge critical value relative to closing door
The detection temperature of food inspection sensor 48 when 2a, 2b sets the high value of steady temperature.
If starting rapid cooling, make 24 high speed rotation of compressor (2000rpm~4000rpm), the also high speed of box fan 9
While rotation, both it is to beat to make the baffle 20b of the baffle 20a and the second cold duct 11b of the first cold duct 11a
Open state cools down entire refrigerating chamber 2 first to the top of refrigerating chamber 2 and lower part both sides' cool-air feed.Then, in food inspection
The temperature that sensor 48 is detected is to make the first refrigerator pipe in the case of scheduled critical value (critical value of baffle 20a) is below
The baffle 20a of road 11a is in off state.At this point, only from the second cold duct 11b cool-air feeds, the second cold duct 11b due to
Only there is outlet in the lower part of refrigerating chamber 2, so, concentrate cooling region 2D and region 2E as 2 lower part of refrigerating chamber.
Secondly, it is the scheduled critical value (gear lower than baffle 20a critical values in the value that food inspection sensor 48 is detected
The critical value of plate 20b) it is below in the case of, the baffle 20b of the second cold duct 11b is also in off state, stop compressor 24
And the rotation of box fan 9, terminate rapid cooling.In addition, making the opportunity that baffle 20a, baffle 20b are in off state can be with base
Whether judged (step S4) by the predetermined time after starting rapid cooling.
In this way, in the present embodiment, after the opening and closing of door 2a, 2b, being detected cold with food inspection sensor 48
It hides in the case that room lower part put into food, using the first cold duct 11a on main cooling top, mainly cools down the of lower part
After both two cold duct 11b cool-air feeds and entire refrigerating chamber cooling first, it is cold to only use the second cold duct 11b supplies
Gas simultaneously concentrates cooling refrigerating chamber lower part.Especially in the present embodiment, the outlet due to being set on the second cold duct 11b
The opening of outlet 30e, 30f, 30a, the 30b of the gross area of the opening area of 30c, 30d than being set to the first cold duct 11b
The gross area of area is small, therefore improves the wind speed of the cold air supplied to the rapid cooling section of 2 lower part of refrigerating chamber, can be effectively
The cooling space.Also, in the case where carrying out only using the cooling of the second cold duct 11b after door 2a, 2b opening and closing at once,
Due to the high influence of refrigerating chamber bulk temperature, the food of lower part is difficult to cool down, therefore such as above-mentioned, carries out using two pipelines first
Cooling.
As a result, can inhibit the food in the pot of refrigerating chamber lower part mild chafing dish is put into refrigerating chamber lower part
The food temperature of surrounding rises and prevents from deteriorating.In addition, sub-cooled remote refrigeration of food in mild pot can be inhibited
Room top and reduce consumption electric power.
Here, even if explanation carries out cooling situation with the second cold duct 11b if refrigerating mode in above-mentioned Fig. 8,
In refrigerating mode in Fig. 8, using detection the temperature inside the box until the second temperature sensor 42 of refrigerating chamber lower part is controlled, press
The rotary speed of contracting machine 24 and box fan 9 is also low speed rotation.For this, in the refrigerating mode of automatic rapid cooling,
Controlled using the food inspection sensor 48 being set near the rapid cooling section of refrigerating chamber lower part, make compressor 24 with
And the rotary speed of box fan 9 rises to high speed rotation.Therefore, the input of mild food and opposite can accurately be detected
Quickly and efficiently cold air is made to contact in its food.
Also, the not only automatically rapid cooling if the lower part input food in refrigerating chamber 2, also by by control panel
In the case that the selection of equal progress, user set, can not also discussing the presence or absence of food inspection, all forcibly rapid cooling is cold
Hide the lower part of room 2.
Secondly, using each temperature sensor and each cold duct, about 2 DEG C low with the temperature compared to 2 top of refrigerating chamber
The control of lower layer's cooling of the temperature of lower of above mode Keep cool room 2 illustrates.Lower layer's refrigerating mode can use control
The setting that panel is turned on/off, in the case where the pattern is set as connection, compared to making baffle the case where setting
The opening state of 20b is elongated (to improve the ratio of the opening state time of the baffle 20b of the opening state time relative to baffle 20a
Example).Specifically, different from the case where setting is disconnected, setting baffle 20a is in off state and only baffle 20b is in an open state
Time.But the rotary speed of the compressor 24 in lower layer's cooling operating such high speed rotation, dimension when not being rapid cooling
Hold low speed rotation (1000rpm~2000rpm).
Secondly, the control in the case of connecting is set as about lower layer's refrigerating mode to illustrate using Figure 17.In lower layer
In cooling operating, compressor 24 stop after pass through the predetermined time in the case of or second temperature sensor 42 detection
In the case that temperature is predetermined critical (baffle critical value) or more, make to make while 24 low speed rotation of compressor baffle 20a,
Both 20b are in an open state.Then, it is that (baffle 20a's is critical for predetermined critical in the detection temperature of second temperature sensor 42
Value) it is below in the case of so that baffle 20a is in off state.Moreover, the detection temperature in second temperature sensor 42 is predetermined faces
In the case of dividing value (critical value of baffle 20b) is below, baffle 20b is also in off state.
Even if in general refrigerator, it may have the Cryogenic air in refrigerator is easy to assemble downwards, even if in refrigerating chamber, phase
Than in top, the tendency of lower part low temperature, but according to the present embodiment, the further difference of the temperature of top and lower part can be made
Change, even the different food of temperature band suitable for preserving also may be selected to distinguish storage place.Moreover, because refrigerating chamber lower part phase
Than low temperature can be remained in general refrigerator, therefore the case where decompression storeroom 35 of Cord blood etc. is saturated because of food
Under, it can be utilized instead of the space of the refrigerating chamber lower part, ease of use is good.Also, lower layer's refrigerating mode is set as disconnected
The case where opening is control as shown in Figure 8, and baffle 20a, 20b always make the two be in an open state on identical opportunity, always in phase
Same opportunity is in off state.In addition, the object space of lower layer's refrigerating mode is than pair as above-mentioned automatic rapid cooling pattern
The 2D+2E (Fig. 3) of image space greatly, whole spaces between shelf 34b and shelf 34e.
In the present embodiment, have and carried out automatically if input food in the predetermined interval of refrigerating chamber lower part if detecting
The above-mentioned automatic rapid cooling pattern of rapid cooling makes refrigerating chamber lower part low temperature and makes and refrigerating chamber compared to the when of setting is disconnected
Above-mentioned lower layer's refrigerating mode that the temperature difference on top becomes larger, the on-off of the setting in these patterns always with one-off simultaneously
It carries out.That is, can not be set as only making above-mentioned automatic refrigerating mode be connect and make lower layer's refrigerating mode be disconnect, make it is above-mentioned automatic
Rapid cooling pattern is to disconnect and lower layer's refrigerating mode is only made to be connection.In this way, above-mentioned due to that can be switched simultaneously with once-through operation
Two patterns, therefore improve the convenience of user.
In addition, above-mentioned two pattern concurrently set for connection in the case of, compared to be set as one by one connect
Situation improves cooling effect.I.e., it is assumed that only above-mentioned automatic rapid cooling pattern is set as the case where connecting being capable of cooling throwing ahead of time
Enter the food in rapid cooling section, but it is temperature to be placed into other food in the refrigerator space other than rapid cooling section
Spend relatively high state.Therefore, in rapid cooling section shortly after input food, the temperature of other food that has been stored in
In the case of rising, there is a possibility that more than refrigerating temperature zone.On the other hand, it is assumed that only above-mentioned lower layer's refrigerating mode is set as
The case where connection, the cooling food for putting into rapid cooling section are natural slowly, compare there is also being in and
The possibility that other food of the speech lower state of temperature are cooled excessively.In this way, by by above-mentioned automatic rapid cooling pattern
It is concurrently set with above-mentioned lower layer's refrigerating mode to connect, it can be achieved that being quickly cooled down the food newly put into and inhibiting to being stored in
Food the cooling operating that influences of temperature.
In addition, being set to decompression storeroom 35, the heat-insulated partition walls between refrigerating chamber 2 and ice-making compartment 3, upper layer freezing chamber 4
28, the component of feedwater piping 64 of ice making etc. is due to attached in ice-making compartment 3, the upper layer freezing chamber 4 in cryogenic temperature band
Closely, it therefore is easy to become low temperature.Therefore, in order to which these components remain the temperature that do not freeze, in heat-insulated partition walls 28 and subtract
While pressing the bottom surface side setting decompression storage compartment temperature of storeroom 35 to ensure heater 65, and water supply interior in heat-insulated partition walls 28
The bottom surface side setting feedwater piping temperature of pipeline 64 ensures heater 66 (Fig. 4).
Moreover, if lower layer's refrigerating mode, automatic rapid cooling pattern is made to be set as connecting, above-mentioned component is easy into one
Walk low temperature.Therefore, as shown in figure 19 when these are set as connecting, when being compared to disconnection setting, make decompression storage compartment temperature
It ensures that heater 65, feedwater piping temperature ensure that the conduction time of heater 66 is long, is more reliably prevented from and freezes.Also, due to
These temperature ensure that the purpose of heater is to prevent the reduction of temperature, therefore more than make the conduction time of heater extended side
Method, even improving the other methods of the output of heater, purpose can also be reached.
