Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment one
The control method of a kind of refrigerator air door that the present embodiment provides, comprises the steps:
Steps A: the actual temperature gathering each room of refrigerator, obtains the actual temperature value of each room, be designated as T
room between i, wherein i is positive integer, and i=1 ~ n, n are the number of room between refrigerator;
Step B: the target temperature value T setting each room
i target, and by formula Δ T
i=T
room between i– T
i target, obtain the temperature gap Δ T of each room
i, wherein, T
i targetthe door opening temperature preset for room between correspondence or air door closing temperature;
Step C: set the first reference value N and the second reference value M, wherein N<M, and the air door controlling each room by following three conditions:
As Δ T
iwhen being all less than or equal to N, then the air door Close All of each room, simultaneously compressor shutdown, after the time period t of interval setting, then return steps A;
As Δ T
iwhen being all more than or equal to M, then compressor start work, the air door of each room is all opened simultaneously, after the time period t of interval setting, then returns steps A;
Under other conditions, then compare each temperature gap Δ T
isize, between opening corresponding to maximum temperature difference, the air door of room, closes the air door of all the other each rooms, after the time period t of interval setting, then returns steps A.The object of the airdoor control under this condition be in order to allow actual temperature value maximum with the temperature gap of corresponding target temperature value between room fast-refrigerating.
Step D: record the door opening of each room or the duration t of closed condition
i continues, and by duration t
i continuesrespectively with the duration t preset
ifmake comparisons:
If t
i continuesin have and be more than or equal to default duration t
if, then between correspondence the air door action of room once, air door action once refers to: if air door was opening originally, then the action reopened again after performing the closedown of main air intake; If air door was closed condition originally, then the action of again closing again after performing the unlatching of main air intake.Its object is for preventing air door to be failure to actuate for a long time and being frozen in.
Wherein, in step C, the span of the first reference value N is: 0<N≤5, and the span of the second reference value M is: 5<M≤30, and the span of t is: 0.1 minute≤t≤5 minute.In step D, t
ifspan be: 30 minutes≤t
if≤ 120 minutes.
Embodiment two
As preferred embodiment, in the control method of above-mentioned refrigerator air door, refrigerator has an evaporimeter, in each room of refrigerator, be provided with room between evaporimeter be between room 1, between the air door of room 1 include a room one and to blow an air door 1a and room one return air air door 1b, the air door of all the other rooms has only included air-supply air door, between in above-mentioned control method pair the control of the air door of room 1 to refer to pair between room one to blow the Synchronization Control of air door 1a and a room one return air air door 1b.
Below to do following description with the refrigerator of room between two to the method implementation process:
See Fig. 1, refrigerator has room and tool evaporimeter 3 between two, be provided with room between evaporimeter 3 be between room 1, another room be between room 22, between the air door of room 1 include a room one and to blow an air door 1a and room one return air air door 1b, the air door of a room 22 has only included a room two and to have blown air door 2a.Between room 1 refrigeration by pair between a room one air door 1a and room one return air air door 1b that blows carry out Synchronization Control, the refrigeration of a room 22 is controlled by a room two air door 2a that blows.The control method of this refrigerator air door comprises the steps:
Steps A: the actual temperature of room 1 and a room 22 between collection, obtains the actual temperature value of room between two, be designated as T
1 room, T
2 rooms;
Step B: the target temperature value T of room between setting two
1 target, T
2 targets, and by formula Δ T
i=T
room between i– T
i target, obtain the temperature gap Δ T of room between two
i, i.e. Δ T
1=T
1 room– T
1 target, Δ T
2=T
2 rooms– T
2 targets, wherein, T
1 targetthe door opening temperature preset for a room 1 or air door closing temperature, T
2 targetsthe door opening temperature preset for a room 22 or air door closing temperature;
Step C: set the first reference value N and the second reference value M, wherein N<M, and 0<N≤5,5<M≤30, and the air door controlling room between two by following three conditions:
As Δ T
1with Δ T
2when being all less than or equal to N, then the air door Close All of room between two, simultaneously compressor shutdown, after the time period t of interval setting, then return steps A, the span of t is: 0.1 minute≤t≤5 minute;
As Δ T
1with Δ T
2when being all more than or equal to M, then compressor start work, between two, the air door of room is all opened simultaneously, after the time period t of interval setting, then returns steps A;
Under other conditions, then compare two temperature gap Δ T
1with Δ T
2size, between opening corresponding to maximum temperature difference, the air door of room, closes the air door of room between all the other, after the time period t of interval setting, then returns steps A.
Δ T is drawn if such as compare
1be greater than Δ T
2, then between, the room two air door 2a that blows closes, and a a room one air door 1a and room one return air air door 1b that blows opens; Otherwise a room two air door 2a that blows opens, a a room one air door 1a and room one return air air door 1b that blows closes.The beneficial effect of this control law is adopted to be in the present embodiment: the target temperature value T set when a room 22
2 targetstime lower, for meet between room 22 each several part temperature particularly bottle frame temperature reach the target temperature value T of setting as early as possible
2 targets, between closedown, between room 1, blow an air door 1a and room one return air air door 1b in room one, can ensure larger blast and air quantity is delivered to a room 22, thus between ensureing, room 22 reaches the target temperature value T of its setting sooner
2 targets.
Step D: the door opening of room or the duration t of closed condition between recording two
1 continues, t
2 continue, and by duration t
1 holds continuous, t
2 continuerespectively with the duration t preset
ifmake comparisons:
If t
1 continues, t
2 continuein have and be more than or equal to default duration t
ifthen between correspondence the air door action of room once, air door action once refers to: if air door was opening originally, then the action reopened again after performing the closedown of main air intake; If air door was closed condition originally, then the action of again closing again after performing the unlatching of main air intake.Wherein, t
ifspan be: 30 minutes≤t
if≤ 120 minutes.
The control method of a kind of refrigerator air door disclosed by the invention, can realize the object that each room reaches default target temperature fast, ensures refrigeration system Effec-tive Function simultaneously.For windy door refrigerator, can meet user suddenly after a lot of food is put in a certain room, room needs the demand of fast-refrigerating around here; There is for windy door the refrigerator of temperature-changing chamber function, if desired unexpected room between is become freezing function from cold storage function, or the target temperature set between room between two differs greatly, now need the target temperature corresponding room being reached fast setting, can be realized by method provided by the invention.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
