In table 2, on, which represents refrigeration mark and corresponds to, to be started, and off represents refrigeration mark and corresponds to closing.As described above, The present embodiment can also carry out branch air supply device the case where there are two storage space and more than three storage spaces to tool State adjustment.

Step S1210 judges whether fast-refrigerating is completed according to refrigeration situation, in step S1210, a kind of concrete implementation Process are as follows: the temperature of storage space current first to meet IRT1 < IR1-off, IRT2 < IR2-off, IRT3 < IR3-off simultaneously All conditions close air door if having met, exit high revolving speed mode；If not satisfied, then judge whether RT < R-off, if RT be greater than or equal to R-off then enter step S1212, if RT < R-off, judge the temperature of storage space with and meanwhile meet The all conditions of IRT1 < IR1-on, IRT2 < IR2-on, IRT3 < IR3-on equally close air door if having met, and exit high turn Fast mode, if not satisfied, judging whether to meet RT < (R-off-k), that is, refrigeration room environmental mean temperature RT already below R- Off reaches k degree, and wherein k closes air door if meeting RT < (R-off-k) for preset constant, high revolving speed mode is exited, if RT More than or equal to R-off-k, then S1212 is entered step.Air door is being closed, is exiting after high revolving speed mode, can also judge cold Freeze whether room temperature FT meets FT < F-off, if so, close compressor, enters step S1212, if being otherwise directly entered step S1212。

Step S1212 returns to freezing chamber refrigeration control process, such as returns to step S1102.

Step S1214, into normal zone refrigeration control flow.

Figure 21 is normal refrigeration stream in the zone refrigeration control method of cold compartment of refrigerator according to an embodiment of the invention The logical flow chart of journey.The normal cooling flow suitable for cold compartment of refrigerator mean temperature increase, according to storage room situation into The case where row refrigeration.The normal cooling flow mainly comprises the steps that

Step S2102 starts refrigerating chamber zone refrigeration.The step can carry out after the step S1214 shown in Figure 12.

Step S2104 drives blower and refrigeration air door starting.A kind of concrete implementation process of step S2104 are as follows: first Judge whether to meet RT > R-on, if meeting RT > R-on, judge whether blower is opened, if having turned on, refrigeration air door is set In open state, the step S2108 that then keeps straight on returns to step S2112 if blower is not opened, if RT is less than or equal to R- On then judges to refrigerate whether air door is open state, then enters step S2104 if open state, if refrigeration air door is to close State then returns to step S2112.

Step S2106 judges to refrigerate indoor environment mean temperature and/or the temperature of each storage space memory storing articles is It is no to meet preset refrigeration chamber stop condition；When meeting refrigeration chamber stop condition, refrigeration air door is closed, then directly It connects and returns to step S2112, if being unsatisfactory for refrigeration chamber stop condition, execute step S2108.

Step S2108, the opening temperature threshold value being arranged using multiple storage spaces and closing temperature threshold value determine refrigeration Mark, the step judge that process is essentially identical with step S1206 in Figure 12, are judged respectively multiple storage spaces, determine Respective refrigeration mark out.

Step S2110 determines branch air supply device according to the state for setting gate1, gate2, gate3 in step S2108 Operating status, and branch air supply device is driven to run on the state.The basic phase of process of the step and step S1208 in Figure 12 Together, the state of branch air supply device and the corresponding relationship of gate1, gate2, gate3 are as shown in table 2.

Step S2112 returns to freezing chamber refrigeration control process, such as returns to step S1102.

For refrigeration chamber stop condition used in above step S2106 there are many form, Figure 22 is according to the present invention one The logical flow chart that refrigeration chamber stops is judged in the zone refrigeration control method of the cold compartment of refrigerator of a embodiment, in step After S2202 starting refrigeration chamber stopping judges process, it perform the following steps in sequence:

Step S2204 judges whether the institute for meeting IRT1 < IR1-off, IRT2 < IR2-off, IRT3 < IR3-off simultaneously It has ready conditions, if having met, closes refrigeration air door, execute the step S2112 in Figure 21；If being unsatisfactory for executing step S2206；

Step S2206 judges whether to meet RT < R-off, i.e. the environment mean temperature of refrigerating chamber is lower than default closing temperature Threshold value, if RT < R-off executes the judgment step of step S2208, if RT is more than or equal to R-off, the step in directly execution Figure 21 S2108；

Step S2208 judges whether to meet simultaneously IRT1 < IR1-on, IRT2 < IR2-on, all of IRT3 < IR3-on Part executes the step S2112 in Figure 21 if then closing refrigeration air door；If being unsatisfactory for executing the judgment step of step S2210；

Step S2210 judges whether to meet RT < (R-off-k), that is, refrigeration room environmental mean temperature RT is Reach k degree lower than R-off, i.e. the difference that R-off and RT subtract each other is greater than k, and wherein k is preset constant, represents above second allowance Value executes the step S2112 in Figure 21 if then closing refrigeration air door；Directly execute the step S2108 in Figure 21.

Figure 22 shows a kind of optional situation of refrigeration chamber stop condition, judges in process in some optional simplicity, The step of step S2204 and step S2206 can also only be executed, closes refrigeration air door after determining RT < R-off, executes figure Step S2112 in 21, if RT is more than or equal to R-off, the step S2108 in directly execution Figure 21, so that step be omitted S2208 and step S2210.By test, the refrigeration stop condition of the omission also can achieve the effect of control, but be worse than The process of whole Figure 22.
