2. the design temperature that will switch chamber 18 is set in the control when lower than present the temperature inside the box
The control method that the design temperature that switches chamber 18 is set in when lower than present the temperature inside the box has 4 kinds, is illustrated successively below.
(1) first kind of control method
According to first kind of control method of the explanation of the table among Figure 14.
First kind of control method is under the situation of having switched design temperature, makes compressor 46 work forcibly, and the switching chamber of damper device 32 is opened with damper 40, sends into cold air forcibly, reduces the temperature inside the box that switches chamber 18.Then, the temperature inside the box according to switching chamber 18 correspondingly makes this compressor 46 stop.Figure 14 shows this and makes it to stop temperature and promptly cool off and stop temperature, for example, is switching under the situation of cryogenic temperature from refrigerated storage temperature, makes cooling stop temperature and is-28 ℃, under the situation that has arrived this temperature, compressor 46 is stopped.In addition, make compressor 46 duration of works forcibly, cold air is being given switched the chamber and be in closed condition forcibly with the damper of damper 40 other chambers such as refrigerating chamber damper in addition.Owing to do like this, other chamber can not be cooled to below the required temperature.
If this control method, then owing to send into cold air forcibly, so can arrive design temperature quickly, the temperature inside the box that switches chamber 18 simultaneously can not drop to below the required temperature.
(2) second kinds of control methods
According to second kind of control method of the explanation of the table among Figure 15.
Second kind of control method is the same with first kind of control method, makes compressor 46 work forcibly, after its moment that stops to be set in passed through official hour (stopping temperature to call cooling in the following text).Table 6 shows this cooling and stops temperature, is for example switching to from refrigerated storage temperature under the situation of cryogenic temperature, after 60 minutes compressor 46 is stopped.
Even this control method, the temperature inside the box that switches chamber 18 also can become design temperature quickly, and the temperature inside the box can not drop to below the required temperature simultaneously.
(3) the third control method
The third control method is the method after first kind of control method improved, and its difference is that changing cooling according to environment temperature stops temperature.For example, environment temperature is low more, just cooling is stopped temperature and sets highly more.
If this control method, even when then environment temperature is low, the temperature inside the box can not drop to below the required temperature yet.
(4) the 4th kinds of control methods
The 4th kind of control method is the method after second kind of control method improved, and is to stop temperature according to environment temperature change cooling.For example, under the low situation of environment temperature, shorten the time (cooling dwell time) that makes compressor 46 work, the temperature inside the box that switches chamber 18 can not drop to below the required temperature.
As mentioned above, if the refrigerator of the first embodiment of the present invention, then the design temperature that switches the chamber set than the high situation of present the temperature inside the box under, make heater work, the temperature of switching chamber interior is risen, so can arrive design temperature quickly.
In addition, the design temperature that switches the chamber set than the low situation of present the temperature inside the box under, second control device makes compressor operating forcibly, cool-air feed is so can promptly arrive design temperature.
Secondly, as second embodiment of refrigerator 10 of the present invention, the situation of utilizing bottom surface heater 62 and side heater 66 controls to switch the temperature inside the box of chamber 18 is described.
Its control method is as described below two kinds, and next coming in order are illustrated.
(1) first kind of temperature-controlled process
This first kind of temperature-controlled process is to control bottom surface heater 62 and side heater 66 with the environment temperature that refrigerator 10 is set with matching.Be described according to Figure 16.Figure 16 represents the intensity of heater and the relation of environment temperature, and the longitudinal axis is represented the intensity of heater, and transverse axis is represented environment temperature.
When environment temperature was low, the temperature inside the box that switches chamber 18 was also low.Therefore, environment temperature is T1 (for example 15 ℃) when following, and the intensity of heater is made as " by force ", from T1 arrival T2 (for example 30 ℃) time, the intensity of heater is made as " in ", under the environment temperature more than the T1, the intensity of heater is made as " weak " or disconnects.
(2) second kinds of temperature-controlled process
Second kind of temperature-controlled process is according to having switched the situation behind the design temperature, control bottom surface heater 62 and side heater 66.Be described according to Figure 17.Figure 17 shows design temperature is switched to refrigerated storage temperature or the intensity of bottom surface heater 62 and side heater 66 when refrigerated storage temperature switches to cryogenic temperature from cryogenic temperature.
When cryogenic temperature switches to refrigerated storage temperature, make the common intensity height (H) of strength ratio of heater carry out work.Otherwise, when when refrigerated storage temperature switches to cryogenic temperature, make the common intensity low (L) of strength ratio of heater carry out work, perhaps heater is disconnected.
(3) effect of above-mentioned two kinds of temperature-controlled process
The effect of above-mentioned two kinds of temperature-controlled process is described according to Figure 18 and Figure 19.
Figure 18 represents to switch the temperature inside the box of chamber 18 and the relation of environment temperature, the situation when solid line is represented to implement this control method, and dotted line represents to implement the situation of the existing control method of non-control method.
Figure 19 represents to switch the temperature inside the box and the time relation of chamber 18, being illustrated in 0 constantly will set from cryogenic temperature and switch to situation behind the refrigerated storage temperature, situation when solid line is represented to implement this control method, dotted line represent to implement the situation of the existing control method of non-control method.
As shown in figure 18, under existing situation, if environment temperature low (15 ℃), even design temperature is set in refrigerated storage temperature (3 ℃), the temperature inside the box can only reach 0 ℃ can not reach the goal-setting temperature before.In contrast, under the situation of this control method,, also can reach 3 ℃ design temperature even environment temperature is 15 ℃.And, under existing situation,, then exist the trend that the temperature inside the box and this environment temperature consistently rise, but under the situation of this control method if environment temperature changes to 30 ℃ from 15 ℃, the temperature inside the box be certain, promptly 3 ℃.This is because utilize first kind of temperature-controlled process, as one man adds the inside of hot-swap chamber 18 with environment temperature, so can not be subjected to the influence of environment temperature.
Secondly, as shown in figure 19, under the situation of this control method, the refrigerated storage temperature that reaches 3 ℃ takes about 3 hours, and is different therewith, under existing situation, takes about 5 hours.That is, when carrying out this control, can promptly reach the target refrigerated storage temperature.This is because utilize second kind of temperature-controlled process, the design temperature that will switch chamber 18 set than the high situation of present the temperature inside the box under, can increase the thermal capacity of heater 62,66, forcibly in the heating cabinet.In addition, under opposite situation, then reduce the thermal capacity of heater 62,66, perhaps with its disconnection.
If the refrigerator of the second embodiment of the present invention of above explanation, then since the design temperature that will switch the chamber set than the high situation of present the temperature inside the box under, can increase the thermal capacity of heater, under opposite situation, can reduce the thermal capacity of heater, so can promptly reach the goal-setting temperature.
In addition, owing to be provided with second control device, it can control the thermal capacity of heater big more when environment temperature is low more, so under the low situation of environment temperature, even design temperature is set to cryogenic temperature from refrigerated storage temperature, also can reach cryogenic temperature reliably.
