Description
Technical field
The present invention relates to radiating control fields, specifically, being related to the change of a kind of radiator control method, this method of realization
Frequency device assembly further relates to the household electrical appliance using this frequency converter assembly, further relates to a kind of computer readable storage medium.
Background technique
Frequency converter is widely used on the household electrical appliance such as air-conditioning, washing machine, also, in general, is provided in frequency converter
Power module, such as IGBT constant power pipe, since power module generates a large amount of heat at work, if heat cannot be timely
It distributes, will lead to heat and gathered on power module periphery and power module is caused to damage, influence the service life of power module, into
And influence the service life of frequency converter.
Therefore, device of the setting for heat dissipation usually in frequency converter, such as radiator fan etc., by radiator fan by function
The heat that rate module generates dispels, and realizes the purpose for reducing temperature of power module.Due in powerful frequency converter, in addition to function
Outside rate module needs to radiate, the device of general strong power part is also required to radiate, thus, system of radiating in big-power transducer
The design of system is particularly significant, needs to carry out in the corresponding radiator fan of the device periphery of power module and strong power part configuration scattered
Heat.
In general, radiator fan is arranged in frequency converter to constitute frequency converter assembly, and controlled by a processor
The work of radiator fan processed, such as processor export control signal to relay switch to control relay switch on-off, relay
Device switch is connected between power supply and radiator fan, and when processor exports closure signal to relay switch, relay is opened
It closes and closes, radiator fan is powered, and when processor exports cut-off signal to relay switch, relay switch is disconnected, radiation air
Fan no power.
Existing frequency converter is that in frequency converter starting, radiator fan is just started to work, frequency conversion to the control of radiator fan
Radiator fan is closed when device stops working, or uses simpler mode, and frequency converter works always once powering on radiator fan.
After the radiator fan control logic figure of existing frequency converter assembly is as shown in Figure 1, work as frequency converter energization, the on-off of radiator fan
Instruction is all high level signal, i.e. radiator fan continues working, and the working condition of radiator fan and power module, strong power part
Device temperature it is unrelated.
But the calorific value of each device is related with the operation power of frequency converter in frequency conversion tank, the operation power of frequency converter is got over
Big calorific value is also bigger, and when frequency converter operation power is small, the calorific value of device is smaller in frequency conversion tank, and frequency conversion in-cabinet temperature is not
Height, radiator fan can not work.If radiator fan continues working, the service life of radiator fan is not only influenced, can also be led
Send a telegraph the waste of energy.
In addition, under existing control logic, radiator fan is still constantly in when short trouble occurs for radiator fan
Energized state will lead to radiator fan continuous heating and more serious accident caused to occur.Under existing control model, heat dissipation
The working time of fan is longer, influences the service life of radiator fan, also will affect the reliability of frequency converter work.
Summary of the invention
The first object of the present invention be to provide a kind of extension radiator fan service life and improve frequency converter assembly use can
By the radiator control method of property.
The second object of the present invention is to provide a kind of frequency converter assembly for realizing above-mentioned radiator control method.
The third object of the present invention is to provide a kind of household electrical appliance using above-mentioned frequency converter assembly.
The fourth object of the present invention is to provide a kind of computer readable storage medium for realizing above-mentioned radiator control method.
The first purpose to realize the present invention, radiator control method provided by the invention include acquisition heat source temperature, and
Climbing speed of the heat source temperature within the unit time is calculated, as climbing speed of the heat source temperature within the unit time is greater than on default
Raising speed rate then issues the instruction for stopping radiator work.
By above scheme as it can be seen that judging whether the radiators such as radiator fan go out by the climbing speed for detecting heat source temperature
Existing failure stops the work of radiator once radiator breaks down, and avoids continuing to be powered and lead after radiator breaks down
The problem of causing radiator damage.In this way, the service life of radiator can be extended, and then extend the use longevity of frequency converter assembly
Life, and improve the reliability of frequency converter assembly.
One Preferable scheme is that, confirm that climbing speed of the heat source temperature within the unit time is greater than default climbing speed
Afterwards, it also executes: issuing the prompt information of radiator failure.
It can be seen that can be confirmed that radiator breaks down after heat source temperature climbing speed is too fast, being prompted by issuing
Information can allow user or service personnel to overhaul in time to radiator, while the reason of also user is allowed to know failure, into
Row targetedly maintenance, avoids the wrong damage repaired frequency converter assembly and lead to frequency converter assembly.
Further embodiment is to confirm that climbing speed of the heat source temperature within the unit time is greater than default climbing speed packet
It includes: calculating the heat source temperature single climbing speed within the unit time at least twice, and confirm in the unit time at least twice
Single climbing speed is greater than default climbing speed.
As it can be seen that radiator failure is just determined after the climbing speed detection repeatedly to heat source temperature, it can be to avoid
Lead to false judgment because of single primary erroneous detection, improves the accuracy judged radiator state.
Further scheme is to calculate single climbing speed of the heat source temperature at least twice within the unit time to include:
Heat source temperature is calculated in the single climbing speed in unit time first time and is confirmed on the single in unit time first time
After raising speed rate is greater than default climbing speed, single climbing speed of the heat source temperature within second of unit time is calculated.
It can be seen that after the single climbing speed only calculated within unit time first time is greater than default climbing speed,
It just executes second and calculates, can cause the operand of processor is excessive to ask to avoid multiple calculating is executed every time in this way
Topic.
Further scheme is that the single climbing speed confirmed within unit time first time is greater than default climbing speed
Afterwards, after preset interval time, single climbing speed of the heat source temperature within second of unit time is calculated.
As it can be seen that the single climbing speed in unit time twice in succession calculate between there is certain interval time, can
To improve the accuracy for judging radiator working condition, avoid being influenced because of the fluctuation in the temperature detecting module short time to scattered
Hot device whether the judgement of failure.
Further scheme is to confirm that the single climbing speed in unit time first time is greater than default climbing speed
Afterwards, the single climbing speed such as heat source temperature within second of unit time is not more than default climbing speed, then confirms heat source temperature
The climbing speed spent within the unit time is not more than default climbing speed.
It can be seen that will not recognize if the single climbing speed judging result twice in succession in the unit time is not identical
For radiator failure, in this way it is possible to prevente effectively from erroneous judgement to radiator failure situation.
One optional scheme is that the instruction that sending stops radiator work includes: to issue open command to switching device,
Wherein, switching device is connected between radiator and power supply, specifically, switching device is relay switch.
As it can be seen that controlling the start and stop of radiator by switching devices such as relay switches, it may be convenient to realization pair
The control of radiator working condition, and control circuit design is very simple.
One optional scheme is such as to confirm climbing speed of the heat source temperature within the unit time no more than default upper raising speed
Rate also executes: judging whether heat source temperature is higher than the first temperature threshold, if so, the instruction of output radiator starting work.
It can be seen that being not starting radiator work at once, but reaching one in heat source temperature after frequency converter starting
Just start work after fixed temperature, it in this way can be to avoid radiator works long hours after frequency converter starting and influences radiator
Service life.
Further embodiment is such as to confirm that climbing speed is not more than default climbing speed, also executes: judging that heat source temperature is
It is no to be lower than second temperature threshold value, if so, the instruction that output radiator stops working；Wherein, second temperature threshold value is lower than the first temperature
Spend threshold value.
As it can be seen that, if heat source temperature declines, radiator will stop working, can keep away in this way in the frequency converter course of work
Exempt from the service life that radiator worked long hours and influenced radiator after frequency converter starting.
To realize the second purpose for being, frequency converter assembly provided by the invention has frequency converter and radiator, heat dissipation

Reason device and memory, memory are stored with computer program, and processor, which executes the computer program, can be achieved on the heat dissipation
Device control method.Frequency converter assembly of the invention can be applied on the household electrical appliance such as air-conditioning, washing machine.
Radiator control method embodiment:
The present embodiment is applied on frequency converter assembly, and frequency converter assembly includes a frequency converter, and is provided in frequency converter
Power module, such as powerful field-effect tube, IGBT etc. in addition, being additionally provided with forceful electric power device in frequency converter, such as rectify
All there may be a large amount of heats during the work time for device, inverter etc., these power modules and forceful electric power device, therefore, become
Frequency device assembly is provided with radiator, which is provided with radiator fan, by radiator fan by the heat of the generations such as power module
Amount is blown away, to realize the function of cooling.
Circuit board is provided in radiator, be provided with referring to fig. 2, on circuit board processor 11, start-up and shut-down control module 14 with
And relay switch 16, in addition, being additionally provided with temperature detecting module 12 in frequency converter assembly, it is preferred that temperature detecting module 12
For temperature sensor, temperature sensor be can be set on 13 periphery of heat source, such as power module or forceful electric power device is arranged in
Periphery, in order to accurately detect the temperature of such as power module, forceful electric power device.Certainly, temperature sensor can also be with power
The heat sources 13 such as module, forceful electric power device are arranged on same circuit board, are also able to detect the temperature of heat source in this way.
After temperature detecting module 12 detects the temperature of heat source 13, temperature value detected is transmitted to processor 11, by
Processor 11 calculates climbing speed of the temperature of heat source 13 within the unit time and also judges certainly the temperature of heat source 13,
The temperature of heat source 13 is compared with predetermined temperature threshold value, judges whether the temperature of heat source 13 is excessively high.
In the present embodiment, start-up and shut-down control module 14 can receive the instruction of the sending of processor 11, and processor 11 is to start and stop control
The instruction that molding block 14 issues is the instruction for controlling the starting of radiator fan 15 or stopping, specifically, being indicated with high level signal
It controls radiator fan 15 to start, indicates that control radiator fan 15 stops with low level signal.In order to control the work of radiator fan 15
Make, relay switch 16 is connected between power supply and radiator fan 15, and start-up and shut-down control module 14 receives the transmission of processor 11
After instruction, corresponding level signal is exported to relay switch 16, to control the closure or disconnection of relay switch 16.
Specifically, processor 11 can be the device that single-chip microcontroller etc. has data-handling capacity, a pin of single-chip microcontroller
High level signal or low level signal are exported to start-up and shut-down control module 14, and start-up and shut-down control module 14 can be a Sofe Switch
Device, such as triode or field-effect tube, which receives the level signal of single-chip microcontroller output, and controls relay switch
16 coil is powered or no power.For example, start-up and shut-down control module 14 is a triode, the base stage of the triode is connected to list
One pin of piece machine, the collector of triode are connected to power supply, and emitter is connected to the coil of relay switch 16.Work as monolithic
When machine exports high level signal, the coil of triode ON, relay switch 16 is powered, and relay switch 16 is closed, radiation air
15 starting work of fan.When single-chip microcontroller exports low level signal, triode cut-off, the coil no power of relay switch 16, after
The contact of electric switch 16 disconnects, and radiator fan 15 stops working.
The control method of radiator is introduced below with reference to Fig. 3.Firstly, executing step S1, processor 11 passes through temperature detection
Module 11 obtains the temperature value of heat source 13, such as the temperature of detection power module or forceful electric power device.Preferably, if power
Module and the quantity of forceful electric power element are multiple, and are distributed in different positions, and multiple temperature sensors point can be respectively set
The temperature of different power modules, forceful electric power device is not detected, and multiple and different radiator fans is set, each radiator fan
It radiates for one or more adjacent power module, forceful electric power device.
Then, step S12 is executed, climbing speed of the heat source temperature within the unit time is calculated.For example, the unit time can be with
It is set as 1 minute or 2 minutes, can also be adjusted according to actual needs.Therefore, temperature sensor is more within the unit time
The secondary temperature value for obtaining heat source 13, such as unit time are set as 1 minute, then temperature sensor repeatedly obtains in 1 minute
Heat source temperature, as at the beginning of one section of detection time, finish time, centre several moment, such as when a length of 1 minute
At interval of the temperature of the heat source 13 of detection in 10 seconds, multiple temperature values available in this way in detection time, and then calculate
Temperature rate-of-rise in unit time such as rises 2 DEG C per minute.
Certainly, if only by once calculating i.e. climbing speed of the confirmation heat source temperature within the unit time greater than default
Climbing speed, it is likely that the case where leading to erroneous detection generation is being unfavorable for the state whether to break down to radiator fan and is carrying out just
Really judgement.Therefore, if it is desirable to confirm that radiator fan breaks down, then needs to contact and be detected within the unit time more than twice
Temperature rate-of-rise to heat source is greater than default climbing speed.
Specifically, referring to fig. 4, after processor receives the heat source temperature numerical value of temperature detecting module transmission, executing step
S11 calculates the single climbing speed of unit time first time inner heat source temperature, and the single climbing speed of the present embodiment is heat source
The rate of the rising calculated of the temperature within a unit time.
Then, step S12 is executed, is judged within unit time first time, whether the single climbing speed of heat source temperature is big
In default climbing speed.Such as the multi collect heat source temperature in one minute, and heat source temperature is calculated in one minute
Variation such as rises 2 DEG C in one minute.It can then calculate within unit time first time, the single climbing speed of heat source temperature
It is 2 DEG C of rising per minute.
If preset default climbing speed is 1.5 DEG C per minute, the judging result of step S12 is yes, execution
Step S14.If in unit time first time that step S11 is calculated, the single climbing speed of heat source temperature is not more than on default
Raising speed rate, then the judging result of step S12 is no, executes step S13, confirms the climbing speed of unit time inner heat source temperature not
Greater than default climbing speed.
If it is confirmed that the single climbing speed of heat source temperature is greater than default climbing speed, then within unit time first time
Step S14 is executed, the single climbing speed of second of unit time inner heat source temperature is calculated.Preferably, list for the first time is being calculated
After heat source temperature single climbing speed in the time of position, after certain time interval, just execute in second of unit time
Heat source temperature single climbing speed calculating.For example, interval time can be set as 2 minutes or 3 minutes.By preset
After interval time, just execute step S14, in this way, can be improved to radiator whether the accuracy of fault detection.
After the single climbing speed for calculating second of unit time inner heat source temperature, step S15 is executed, second of judgement single
Whether the single climbing speed of position time inner heat source temperature is greater than default climbing speed, such as the multi collect heat source in one minute
Temperature, and rate of change of the heat source temperature in one minute is calculated, such as rise 1 DEG C in one minute.It can then calculate
In second of unit time, the single climbing speed of heat source temperature is 1 DEG C of rising per minute.
Then, step S15 is executed, is judged within second of unit time, whether the single climbing speed of heat source temperature is big
In default climbing speed.Such as the multi collect heat source temperature in one minute, and heat source temperature is calculated in one minute
Variation such as rises 1 DEG C in one minute.It can then calculate within second of unit time, the single climbing speed of heat source temperature
It is 1 DEG C of rising per minute.
If preset default climbing speed is 1.5 DEG C per minute, the judging result of step S15 is no, execution
Step S13, that is, the climbing speed of confirmation unit time inner heat source temperature are not more than default climbing speed.If step S14
In second of the unit time calculated, the single climbing speed of heat source temperature is greater than default climbing speed, the then judgement of step S15
It as a result is yes, execution step S16, the climbing speed of confirmation unit time inner heat source temperature, which is greater than, presets climbing speed.
As it can be seen that the present embodiment is by calculating the single climbing speed in unit time inner heat source temperature twice in succession, only
Have single climbing speed twice in succession both greater than default ascending threshold when, just the climbing speed of confirmation heat source temperature is excessively high, i.e.,
The judging result of step S3 be it is yes, can be confirmed that radiator fan breaks down at this time, and execute step S4, the sending of processor 11 stops
The only instruction of radiator fan work, i.e. output low level signal.
After processor 11 issues low level signal, the triode as start-up and shut-down control module 14 will end, and relay is opened
16 coil no power is closed, therefore relay switch 16 is in an off state, radiator fan 15 and power supply disconnect, at this point, heat dissipation
Fan 15 does not work.In this way, disconnecting the power supply of radiator fan 15 in the case where radiator fan 15 breaks down, avoiding radiating
Fan 15 continues to be powered and damage in case of a fault.Since the failure of radiator fan 15 may be because of radiator fan
There is situations such as short circuit in inside, and the power supply of cutting radiator fan 15 can effectively avoid more serious accident from sending out in time at this time
It is raw.
After executing step S4, processor 11 also executes step S5, issues the prompt information of radiator fan failure, such as passes through
Display screen shows the suggestion voice of radiator fan failure, or issues alarm sound by buzzer, or pass through LED light etc.
Light emitting device issues alarm light, in order to prompt user's radiator fan to break down.
If the judging result of step S3 be it is no, i.e. climbing speed of the temperature within the unit time of confirmation heat source is not more than
Default climbing speed, then it represents that radiator fan does not break down, and executes step S6, judges whether heat source temperature is higher than the first temperature
Threshold value is spent, for example, the first temperature threshold can be set as 50 DEG C.If heat source temperature is higher than the first temperature threshold, execute
Step S7, processor 11 issue the instruction of starting radiator fan work, i.e. output high level signal, start-up and shut-down control module 14 is led
Logical, the coil of relay switch 16 is powered, and relay switch 16 is in closed state, and radiator fan 15 powers on and works.
If heat source temperature is not higher than the first temperature threshold, S8 is thened follow the steps, judges whether heat source temperature is lower than second
Temperature threshold, in the present embodiment, second temperature threshold value is lower than the first temperature threshold, such as the first temperature threshold is set as 50 DEG C
In the case where, second temperature threshold value can be set as to 40 DEG C.When heat source temperature is lower than second temperature threshold value, step is executed
S9 is issued and is stopped the instruction that radiator fan works, i.e. the output of processor 11 low level signal, and three as start-up and shut-down control module 14
Pole pipe will end, the coil no power of relay switch 16, therefore relay switch 16 is in an off state, radiator fan 15 with
Power supply disconnects, at this point, radiator fan 15 does not work.
Finally, executing step S10, judge whether frequency converter stops working, if it is, terminating the control to radiator fan
System, such as processor 11 export low level signal, stop the power supply to radiator fan 15.If frequency converter does not stop working,
S2 is then returned to step, calculates climbing speed of the heat source temperature within the unit time again.
The relationship of control level and the temperature of the present embodiment radiator fan is as shown in figure 5, the temperature of only heat source is higher than the
When one temperature threshold TH1, radiator fan just starts work, and when heat source temperature is lower than second temperature threshold value TH2, radiator fan will
It stops working, and the first temperature threshold TH1 is higher than second temperature threshold value TH2, can frequently start to avoid fan in this way, stop
Only.
Since the present embodiment is not the random start radiator fan after frequency converter starting to the control of radiator fan, only
Just will start radiator fan after the temperature of heat source reaches certain temperature, once and the temperature of heat source drop to second temperature
After below threshold value, the work of radiator fan will be stopped, therefore the present embodiment is it is possible to prevente effectively from radiator fan works long hours, from
And extend the service life of radiator fan, also extend the service life of frequency converter assembly.
Further, since radiator fan can be just stopped working after heat source temperature drops to second temperature threshold value or less,
If by the first temperature threshold, second temperature threshold value setting it is relatively reasonable, can be excessively high to avoid heat source temperature and influence frequency converter
The problem of work.
In addition, the present embodiment judges whether radiator fan occurs by climbing speed of the heat source temperature within the unit time
Failure can effectively detect the working condition of radiator fan, the feelings especially whether to break down to radiator fan
Condition is detected, and avoids the continued power after radiator fan breaks down and problem short-circuit, that radiator fan temperature is excessively high occurs.
It is not only to be determined with one-time detection, but pass through continuous several times in unit also, when judging whether radiator fan breaks down
The climbing speed of heat source temperature is detected in time, calculate it is determining, to improve to radiator fan failure state
Judgment accuracy.
Certainly, the present embodiment be by the unit time twice in succession to the detection of the single climbing speed of heat source temperature with
Judge radiator whether failure, practical application uses, and can be continuous three times or continuously in four unit time, heat source temperature
Climbing speed when being greater than default climbing speed, just confirm radiator failure.Also, it is reserved before detection twice in succession
