Specific embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from start to finish
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
The compressor control method of the embodiment of the present invention, compressor control device and refrigerator, can solve to enter compressor
The problem that the compressor that row power is caused when protecting does not start, refrigerator does not freeze, may also help in engineer and developed in refrigerator
Cheng Zhong, from the higher compressor of sexual valence.
The compressor control method for proposing according to embodiments of the present invention is described with reference to the accompanying drawings.
Fig. 1 is the flow chart of compressor control method according to embodiments of the present invention, as shown in figure 1, the compressor control
Method is comprised the following steps：
S1, obtains the status information of compressor.
Specifically, the operation information of compressor can be detected, for example, enabling signal, current power, rotary speed information etc..
S2, according to status information the current state of compressor is judged.
Specifically, in some cases compressor horsepower is higher for refrigerator, thus, in order to avoid compressor horsepower exceedes work(
The damage of rate threshold value assembly, can judge that compressor, whether in power higher state, is convenient for power according to status information
Protection.For example, when refrigerator has just started i.e. compressor start, compressor horsepower is higher；Again for example, refrigerator duty ratio is larger
When, specifically for example, refrigerator is in hot environment and when placement thing is more, and operation power is also higher.
S3, when compressor is currently at the pre- guard mode of power, according to current state rotational speed regulation pattern is determined.
Specifically, the pre- guard mode of power can be understood as compressor in this case power be possible to exceed power-threshold
Value, it should carry out power and protect to avoid the damage to compressor.
In some embodiments of the invention, the pre- guard mode of power includes that starting state and current power are more than power-threshold
One kind of the state of value, that is, power is too high when judging whether compressor has just started or run, and is likely to result in the damage to compressor
It is bad.
In some embodiments of the invention, when compressor is in starting state, it is defined as starting rotational speed regulation pattern；
When compressor is in state of the current power more than power threshold, it is defined as protecting rotational speed regulation pattern.Say, for compression
Power adjusts in different ways the rotating speed of compressor more than the state of power threshold in machine just startup and operation, so that
Its operation power is unlikely to too high and causes to damage.
S4, according to the rotating speed of the rotational speed regulation mode tuning compressor determined.
In an embodiment of the present invention, for the different conditions of compressor adopt different rotational speed regulation modes.Compressor

When, power is higher, and for the different pre- guard modes of power the rotating speed of compressor is adjusted, it is to avoid its power is too high to be caused to damage.
Compressor control method according to embodiments of the present invention, in compressor guard mode pre- in power, for not
Same current state adjusts the rotating speed of compressor using different rotational speed regulation patterns, such that it is able to avoid compressor horsepower
It is too high and cause damage, i.e., by software improve realize power protect, without the need for changing high cost compressor.
Wherein, in compressor start, the power ratio of compressor is higher, using startup rotational speed regulation mode tuning compressor
Rotating speed.Specifically, control compressor and the first Preset Time is run with the first rotating speed, wherein, the first rotating speed is compressor
Minimum permission rotating speed；The rotating speed for adjusting compressor every the second Preset Time increases preset value, until rotating speed of target.Say,
When compressor just starts, compressor first runs such as 5 minutes a period of time with minimum permission rotating speed, then lifts rotating speed step by step,
Each rotating speed runs second Preset Time such as 30 seconds, until switch to rotating speed of target, for example, with current environmental temperature, humidity,
The rotating speed that the temperature of each temperature range matches.Adjust rotating speed by the way of above on startup, just startup can be avoided
When there is the too high phenomenon of compressor horsepower, when reducing refrigerator work, compressor horsepower reaches the situation of peak power restriction, drop
The low damage to compressor.
Wherein, when the current power of compressor is more than power threshold, using protection rotational speed regulation mode tuning compressor
Rotating speed.It is adjusted using following steps, S41, controlling the rotating speed of compressor reduces, and controls compressor with turning after reducing
Speed operation；Whether S42, judge the current power of compressor more than the power threshold；And, S43, if current power is more than
Power threshold, execution step S41, until current power is less than or equal to power threshold.That is, in the current work(of compressor
When rate is limited more than the peak power of setting, start the protection to compressor, but, in an embodiment of the present invention, power is protected
Shield is not simply to control compressor shutdown, but reduces rotating speed by controlling compressor so that compressor drop rotating speed operation
For a period of time come reduce damage.
Further, after the 3rd Preset Time, controlling the rotating speed of compressor increases, and after controlling compressor to increase
Rotating speed operation；Judge the current power of compressor whether more than power threshold；And, if current power is more than power-threshold
Value, return to step S41 reduces again rotating speed operation a period of time so that refrigerator load lifts again rotating speed after diminishing, for example
The rotating speed matched with current environment and refrigerator state is promoted to, so circulation.
Further, if current power is less than or equal to power threshold, control compressor is run with current rotating speed.
So as to ensure compressor horsepower will not be too high and avoid the occurrence of that compressor does not start or refrigerator does not freeze while cause and damage
Situation.
Below by taking frequency conversion refrigerator work as an example, the power protection process during compressor operating of the embodiment of the present invention is carried out
Explanation.As shown in Fig. 2 be the flow chart of the compressor control method of a specific embodiment according to the present invention, including：
S100, the environment temperature, humidity, the temperature of each compartment according to residing for ice selectes compressor operating rotating speed.
S110, compressor operating.
Whether S120, detection compressor horsepower exceedes power threshold, if it is not, then execution step S130, if it exceeds work(
Rate threshold value, execution step S140.
S130, the compressor operating rotating speed for controlling compressor to select runs, and according to actual refrigeration, environment temperature
Degree, humidity, the temperature change of each compartment, adjust rotating speed, that is, carry out normal compressor control, and return to step S120.
S140, control compressor reduces by 1 grade of rotating speed operation.
S150, judges whether compressor horsepower exceedes power threshold, if it is, return to step S140, otherwise, performs step
Rapid S160.
S160, compressor operating T time.
S170, control compressor lifts 1 grade of operation, and return to step S120.
Specifically, when compressor horsepower is detected more than the i.e. power threshold of peak power for setting, send out to compressor
Send rotating speed to drop 1 grade of signal, compressor is run with the rotating speed after downshifting, judge compressor horsepower whether more than the maximum for setting again
Power, if it is, compressor rotary speed continues to downshift, until meeting compressor horsepower is not more than the peak power for setting.Assume this
When compressor rotating speed be P, compressor with select rotating speed P operating T minutes, after T minutes terminate, frequency conversion board give compressor send
Rotating speed rises 1 grade of signal, and compressor is run with the rotating speed after upshifing, and whether judges compressor horsepower more than the peak power for setting,
If not, compressor is with the rotation speed operation, and into the control of normal press；If it is, 1 grade of operation T1 minute drops in compressor
Afterwards, judge whether again to upshift, until into normal compressor control.Wherein, depending on time T is by concrete condition.
In short, the compressor control method of the embodiment of the present invention, may occur power too high for different phase
Situation, using different rotational speed regulation modes.Wherein, during compressor start, first with slow-speed of revolution operation a period of time, then rise step by step
Shelves, are lifted to the rotating speed matched with current environment and refrigerator state；When compressor horsepower is more than peak power limit value, to pressure
The protection of contracting machine is not directly to control compressor shutdown, but control compressor drop rotating speed operation a period of time, make refrigerator load
Upshift again after diminishing, lifted to the rotating speed matched with current environment and refrigerator state.Can solve in correlation technique to pressure
The compressor that contracting machine carries out being caused when power is protected does not start, the problem that refrigerator does not freeze, meanwhile, engineer developed in refrigerator
Cheng Zhong, can select the higher compressor of sexual valence.
The compressor control device that according to a further aspect of the invention embodiment is proposed is described with reference to the accompanying drawings.
Fig. 3 is the block diagram of compressor control device according to embodiments of the present invention, as shown in figure 3, the compressor control dress
Putting 100 includes acquisition module 10, judge module 20, determining module 30 and adjustment module 40.
Wherein, acquisition module 10 is used to obtain the status information of compressor；Judge module 20 is used to be sentenced according to status information
The current state of disconnected compressor；Determining module 30 is used for when compressor is currently at the pre- guard mode of power, according to current shape
State determines rotational speed regulation pattern；Adjustment module 40 is used for the rotating speed according to the rotational speed regulation mode tuning compressor determined.
Specifically, the pre- guard mode of power can be understood as compressor in this case power be possible to exceed power-threshold
Value, it should carry out power and protect to avoid the damage to compressor.Normally, when refrigerator has just started i.e. compressor start, pressure
Contracting acc power is higher；Again for example, when refrigerator duty ratio is larger, specifically for example, refrigerator is in hot environment and places eastern
When Thebe is more, operation power is also higher.In some embodiments of the invention, the pre- guard mode of power includes starting state
With the one kind for the state that current power is more than power threshold, that is, power is too high when judging whether compressor has just started or run,
It is likely to result in the damage to compressor.Further, determine that rotational speed regulation pattern, to adjust the rotating speed of compressor, is kept away according to current state
Exempt from power too high.
In some embodiments of the invention, determining module 30 is used for, and when compressor is in starting state, is defined as opening
Dynamic rotational speed regulation pattern；When compressor is in state of the current power more than power threshold, it is defined as protecting rotational speed regulation mould
Formula.Say, power adjusts in different ways pressure more than the state of power threshold in startup firm for compressor and operation
The rotating speed of contracting machine, so that its operation power is unlikely to too high and causes to damage.
Adjustment module 40 can control compressor and work under multiple different rotating speeds, wherein, compressor slow-speed of revolution work
When, power is relatively low, and during the high rotary speed working of compressor, power is higher, and for the different pre- guard modes of power compressor is adjusted
Rotating speed, it is to avoid its power is too high to be caused to damage.
Compressor control device 100 according to embodiments of the present invention, in compressor guard mode pre- in power, for
Different current states adjusts the rotating speed of compressor using different rotational speed regulation patterns, such that it is able to avoid compressor work
Rate it is too high and cause damage, realize power protect.
Wherein, adjustment module 40 in the case where rotational speed regulation pattern is started, with the first rotating speed operation first preset by control compressor
Time, wherein, the first rotating speed is the minimum permission rotating speed of compressor, and, adjust turning for compressor every the second Preset Time
Speed increases preset value, until rotating speed of target, for example, matches with the temperature of current environmental temperature, humidity, each temperature range
Rotating speed.Adjust rotating speed by the way of above on startup, can avoid occurring compressor horsepower too high phenomenon when just starting,
When reducing refrigerator work, compressor horsepower reaches the situation of peak power restriction, reduces the damage to compressor.
Wherein, adjustment module 40 is performed under protection rotational speed regulation pattern：S41, controlling the rotating speed of compressor reduces, and
Control compressor is run with the rotating speed after reducing；Whether S42, judge the current power of compressor more than power threshold；And,
S43, if current power is more than power threshold, execution step S41, until current power is less than or equal to power threshold.Also
It is to say, when the current power of compressor is limited more than the peak power of setting, starts the protection to compressor, but, at this
In inventive embodiment, power protection is not simply to control compressor shutdown, but reduces rotating speed by controlling compressor,
So that compressor drop rotating speed runs a period of time to reduce damaging.
Further, after the 3rd Preset Time, control the rotating speed of compressor increases adjustment module 40, and controls compression
Machine is run with the rotating speed after increasing, and whether judges the current power of compressor more than the power threshold, and, in current power
During more than the power threshold, execution step S41 reduces again rotating speed operation a period of time so that refrigerator load diminishes it
