Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described by corresponding accompanying drawing.Obviously, described embodiment is only the present invention one
Section Example rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.
According to embodiments of the invention, it is provided that the high-pressure modular guard method of a kind of air purifier, as shown in Figure 1 originally
The flow chart of one embodiment of the method for invention.The high-pressure modular guard method of this air purifier may include that
At step S110, obtain the feedback voltage of times die block of described high-pressure modular.
In one example, high-pressure modular can include high voltage control sections, boosting part and laminate section again.Times die block
I.e. times laminate section in high-pressure modular.
Such as: in voltage mode transformation process, high-pressure modular needs the regular hour to complete the mistake of low pressure liter high pressure
Journey.
Such as: the multiplication of voltage module feedback voltage of low-voltage needs the regular hour, just can be switched to high pressure mode times
Die block feedback voltage.
Such as: voltage sensor can be passed through, obtain the feedback voltage of described high-pressure modular.
Thus, by obtaining the feedback voltage of described times die block, the voltage of described high-pressure modular can be obtained easily
Information, obtains mode easy, obtains result reliability high.
At step S120, when described feedback voltage is consistently less than default reference value in preset duration, determine institute
State high-pressure modular to break down.
Alternatively, described fault, may include that sparking, short circuit at least one.By the concrete fault such as sparking, short circuit
Process, described high-pressure modular reliability of operation and safety can be improved.
Such as: in the voltage mode transformation process of air purifier high-pressure modular, the phenomenon of sparking is easily produced.
Thus, by determining that described high-pressure modular breaks down when described feedback voltage is less than described reference value, it is judged that
Mode is reliable, it is judged that result accuracy is good.
At step S130, based on described fault, when described high-pressure modular is in voltage mode transformation process, if described
The output voltage of described high-pressure modular more than the first high-voltage value preset, is then reduced to described the by the output voltage of high-pressure modular
One high-voltage value.
Such as: in voltage mode transformation process, if the long period (such as: 30ms) is less than the feedback of multiplication of voltage module settings
Reference value U0 of voltage, then it is believed that there is spark phenomenon, carry out reducing output voltage and process.
Such as: when high tension voltage output (more than 6KV) judges sparking, first carry out dropping low-voltage output to process.
Thus, by carry out when High voltage output voltage breaks down reduce output voltage process, processing mode safety, can
Leaning on, and do not interfere with the normal use of described air purifier, hommization is good.
In an optional example, in step s 130, the output voltage of described high-pressure modular is reduced to described first
High-voltage value, may include that the reduction when output voltage to described high-pressure modular carries out tide state processes.
In one example, the reduction when output voltage to described high-pressure modular of step S130 carries out tide state processes
Detailed process, may include that when described air purifier local environment humidity for tide state time, directly make described high-pressure modular by
Damp state the first high-voltage value pattern output voltage preset, the output voltage of described high-pressure modular will be reduced to described first high pressure
Value.
Such as: the example that ginseng is shown in Table 1, after entering tide morphotype formula, it is directly entered the output of 6KV voltage.If there is again
The continuous 30ms of die block feedback voltage is less than the situation of reference value U0, and concrete process sees properly functioning Protection of arcing.And then, at height
Under wet 6KV pattern, the multiplication of voltage continuous 30ms of the module feedback voltage situation less than reference value U0 occur, concrete process is shown in properly functioning
Protection of arcing.
Such as: when being turned low-voltage by high pressure mode, U0 reference value directly switches.
Such as: during by high humidity 15KV pattern change of tide state 6KV pattern, the reference value of U0 is directly switched to 0.287V by 1.11V.
Thus, by the output voltage of described high-pressure modular is carried out tide state time reduction process, can more efficient, more may be used
The safety of described high-pressure modular when safeguarding tide state by ground.
In an optional example, in step s 130, the output voltage of described high-pressure modular is reduced to described first
High-voltage value, may include that the reduction when output voltage to described high-pressure modular carries out high humidity processes.
Below in conjunction with the flow chart of the embodiment that high humidity blood pressure lowering in the method for the present invention shown in Fig. 3 processes, furtherly
The detailed process that reduction when the output voltage to described high-pressure modular of bright step S130 carries out high humidity processes.
Step S310, when the humidity of described air purifier local environment is high humidity, described high-pressure modular acquiescence is by pre-
If high humidity the second high-voltage value pattern output voltage；Under described high humidity the second high-voltage value pattern, when described high-pressure modular occurs
The second timer counter is carried out during described fault.
Step S320, when the second cumulative number that described second timer counter obtains reaches the second preset times, makes institute
State high humidity the first high-voltage value pattern output voltage that high-pressure modular is reduced to preset, will the output voltage drop of described high-pressure modular
The most described first high-voltage value.
Such as: the example that ginseng is shown in Table 1, after entering high wet model, acquiescence presses high humidity 15KV pattern output voltage.At height
Under wet 15KV pattern, if 30ms detects that multiplication of voltage module feedback voltage less than U0, then adds up primary fault, has reached continuously
After number of stoppages N0, enter high humidity 6KV pattern.
Thus, reduction during by the output voltage of described high-pressure modular carries out high humidity processes, can more precisely, more pacify
Entirely realizing the step pressure reducing of described high-pressure modular output voltage during high humidity, reliability can be ensured well.
In an optional example, in step s 130, the output voltage of described high-pressure modular is reduced to described first
High-voltage value, may include that the reduction when output voltage to described high-pressure modular carries out non-high humidity processes.
The flow chart of the embodiment that non-high humidity blood pressure lowering processes in method below in conjunction with the present invention shown in Fig. 4, further
The detailed process that reduction when the output voltage to described high-pressure modular of step S130 carries out non-high humidity processes is described.
Step S410, when the humidity of described air purifier local environment is non-high humidity, described high-pressure modular acquiescence is pressed
Non-high humidity the 3rd high pressure binarization mode output voltage preset；Under described non-high humidity the 3rd high pressure binarization mode, when described high pressing mold
The second timer counter is carried out when block breaks down.
In one example, from humidity from low to high, can be divided into successively: non-high humidity < 70%, high humidity 70%～85%,
Tide state > 80% these 3 stages.
Such as: the example that ginseng is shown in Table 1, after entering not high wet model, acquiescence is by non-high humidity 18KV pattern output voltage.
Under non-high humidity 18KV pattern, if 30ms detects that multiplication of voltage module feedback voltage less than reference value U0, then adds up once continuously
Fault.
Step S420, when the second cumulative number that described second timer counter obtains reaches the second preset times, makes institute
State non-high humidity the second high-voltage value pattern output voltage that high-pressure modular is reduced to preset；In described non-high humidity the second high-voltage value pattern
Under, the second timer counter is carried out when described high-pressure modular breaks down.
Such as: the example that ginseng is shown in Table 1, after having reached number of stoppages N0, non-high humidity 16KV pattern is entered.In not high
Under wet 16KV pattern, if 30ms detects that multiplication of voltage module feedback voltage is less than U0 continuously.
Step S430, when the second cumulative number that described second timer counter obtains reaches the second preset times, then makes
Described high-pressure modular is reduced to non-high humidity the first high-voltage value pattern output voltage preset, will described high-pressure modular output electricity
The most described first high-voltage value of pressure drop.
Such as: the example that ginseng is shown in Table 1, after having reached number of stoppages N0, non-high humidity 15KV pattern is entered.In not high
Under wet 15KV pattern, if 30ms detects that multiplication of voltage module feedback voltage, less than reference value U0, has reached the number of stoppages continuously
After N0, enter non-high humidity 6KV pattern.
Table 1: the value (such as: N0 can be 1～3 with value) of different mode voltage U0 and number of stoppages N0.
Thus, processed by the reduction when output voltage of described high-pressure modular is carried out non-high humidity, can more precisely, more
Being reliably achieved the step pressure reducing of described high-pressure modular output voltage during non-high humidity, safety can be greatly improved, user
The experience used is the most more preferably.
In an optional embodiment, after step s 130, it is also possible to including: by the output electricity of described high-pressure modular
Fault treating procedure after the most described first high-voltage value of pressure drop.
Below in conjunction with the flow chart of an embodiment of troubleshooting in the method for the present invention shown in Fig. 2, further illustrate step
The detailed process of the troubleshooting after rapid S130.
