Fig. 9 be refrigerating device according to an embodiment of the invention except oxygen control method schematic diagram.This method
Suitable for having the refrigerating device of electrolysis deoxygenation component 200, and the electrolysis deoxygenation component 200 has to anode plate air-supply
Blower 250.The control method is perform the following steps in sequence:
Step S902 detects that the door body of refrigerating device opens trigger signal.
Step S904 judges whether electrolysis deoxygenation component 200 is in running order.Above-mentioned electrolysis deoxygenation component 200 is in
Working condition refers to: the connection line of battery and anode plate and cathode plate is connected, and electrolysis deoxygenation component 200 is being electrolysed storing sky
Interior oxygen.In the present embodiment, can judge by the way that whether the connection line of battery and anode plate and cathode plate is connected
Whether in running order it is electrolysed deoxygenation component 200.
Step S906, if the judging result of step S904 is yes, independent closing blower 250.The door body of refrigerating device
When unlatching, if electrolysis deoxygenation component 200 is in working condition, then blower 250 is also necessarily in open state.It is electrolysed deoxygenation
For component 200 using electrolysis deoxygenation, the noise that electrolysis generates itself is smaller, and main noise source is blower 250.When detecting use
Door body is opened at family, and is electrolysed deoxygenation component 200 when being currently running, and individually closes the blower 250 of electrolysis deoxygenation component, and is electrolysed and is removed
Oxygen component 200 continues to be electrolysed deoxygenation, and when preventing user using refrigerating device, the noise that blower 250 generates produces user
It is raw to influence.
Step S908, if the judging result of step S904 is no, off-state and blower of the holding battery for electrical connection
250 closed state, until detecting that door body closes trigger signal.If electrolysis deoxygenation component 200 is in off working state, then
Blower 250 is also at closed state, then keeping the off working state of electrolysis deoxygenation component 200 and the pass of blower 250 simultaneously
Closed state is until detect that door body is closed once again.
Figure 10 be refrigerating device according to an embodiment of the invention except oxygen control method flow chart.This method
It perform the following steps in sequence:
Step S1002 detects that the door body of refrigerating device opens trigger signal.
Step S1004 judges whether electrolysis deoxygenation component 200 is in running order.
Step S1006, if the judging result of step S1004 is yes, independent closing blower 250.If refrigerating device
Door body is opened, and deoxygenation component is in running order, then being first shut off the blower 250 of deoxygenation component.To prevent user from making
When with refrigerating device, the noise that blower 250 generates has an impact user.
Step S1008, if the judging result of step S1004 is no, off-state and wind of the holding battery for electrical connection
The closed state of machine 250, until detecting that door body closes trigger signal.

200 break-ofves.If user further opens container for storing, then disconnecting the connection of battery Yu cathode plate and anode plate again, make
It is electrolysed deoxygenation component 200 and stops electrolysis deoxygenation.When opening container for storing, storage space is connected to user with external environment, in
The atmosphere in portion is destroyed, and cannot achieve deaerating effect being electrolysed deoxygenation component 200 and working on, at this point, disconnected in time
The connection of battery Yu cathode plate and anode plate is opened, to save battery power, while the use of electrolysis deoxygenation component 200 can also be improved
Service life.
Step S1014, if detect the closing trigger signal of container for storing and the closing trigger signal of door body.User makes
After container for storing, can successively close container for storing and door body, refrigerating device can be sequentially received container for storing
Close the closing trigger signal of trigger signal and door body.
Step S1016, if the judging result of step S1014 be it is yes, reclose battery for being electrically connected and opening blower
250.After confirming that user closes door body, electrolysis deoxygenation component 200 is again turned on work, while blower 250 is again turned on.
Step S1018, if the judging result of step S1010 be it is no, keep blower 250 close in the state of, control electricity
Solution deoxygenation component 200 continues working.If user only opens refrigerating device and is not switched on container for storing, then, electrolysis removes
Oxygen component 200 carries out electrolysis deoxygenation in the case where blower 250 is closed, and can not only prevent blower 250 from generating noise in this way, but also
Enable to the atmosphere that rich nitrogen oxygen deprivation is kept inside storage space.
Step S1020 judges whether the closing trigger signal for detecting container for storing.After user's use, it can close
Door body, refrigerating device can receive the closing trigger signal of door body.
Step S1022, if the judging result of step S1020 be it is yes, reopen blower 250.When confirmation user closes door
After body, blower 250 is again turned on, and keeps unlatching work synchronous with electrolysis deoxygenation component 200.
Step S1024, control electrolysis deoxygenation component 200 are run according to preset operating mode.Shape is remained turned-off in door body
When state, control electrolysis deoxygenation component 200 is according to the operating mode discontinuous operation set.Meanwhile blower 250 is in electrolysis deoxygenation group
Part 200 is opened when working, and is remained turned-off when being electrolysed deoxygenation component 200 and not working.Specifically, above-mentioned electrolysis deoxygenation component 200
Preset operating mode are as follows: electrolysis deoxygenation component 200 connect battery for electrical connection continue working the first preset time after, disconnect
Battery for be electrically connected the second preset time of break-off, and recycle above-mentioned steps interval start and stop work.It is above-mentioned first it is default when
Between and the second preset time according to the size of storage space and the working efficiency of deoxygenation component 200 can be electrolysed be determined,
In the present embodiment, the first preset time can be set as 1 hour, and the second preset time can be set as 5 hours.
