In any situation, wherein M be preset constant, represent a certain storage room occur temperature higher than the first storage room unlatching
The article of cryogenic temperature threshold value M degree, that is, stored high temperature food, drive blower to be run if being judged as YES with high revolving speed, and make
Compressor is run with high revolving speed, if being judged as NO, judges whether compressor is in high-speed state, if compressor is not in high turn
Fast state thens follow the steps S1214, if compressor is in high-speed state, directly opens refrigeration air door.It is driven in step S1204
The process of dynamic blower, compressor and refrigeration air door includes state deterministic process, if judging to be in the operation shape needed
State does not repeat then to control.In driving blower and compressor high-speed cruising, and after opening refrigeration air door, step is executed
S1206。
Step S1206, the opening temperature threshold value being arranged using multiple storage spaces and closing temperature threshold value determine refrigeration
Mark, is introduced by taking the first storage space as an example, judges IRT1 > IR1-on, if gate1 is set as starting, sentence if not
Whether disconnected gate1 has been starting state, if gate1 is in off state, is judged next storage space, if gate1 is
Open state judges IRT1 < IR1-off, if so, gate1 is set off and is judged next storage space, if not
Directly next storage space is judged, corresponds to other storage spaces such as the second storage space, third storage space, it can be with
Use the deterministic process for being similar to the first storage space.In Figure 12 by taking the deterministic process of three storage spaces as an example, actually make
With in the process, can be increased and decreased according to the quantity of storage space, and the timing of the deterministic process of each storage space
It is not limited, can carry out one by one, can also carry out parallel.

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.

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.

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,
