Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Embodiment 1
As shown in Figure 1, it is；Wherein, the drip tray fault detection and control method, comprising:
Step 100, drip tray water level is obtained in real time；
Water level sensor 2 is set in drip tray, can obtain the water level of drip tray in real time, consequently facilitating according to water receiving
Disk water level carries out subsequent judgement and operation.
Step 200, judge whether drip tray water level is greater than the first watermark threshold；
Wherein, first watermark threshold is the 2/3 of drip tray peak level, is denoted as 2/3L, wherein L expression connects
The peak level that water pond can be contained or be accommodated can with drip tray if drip tray does not indicate peak level in production
Peak level (more again to overflow drip tray) with receiving is the peak level L in the application, if drip tray is indicated in production
It can be in the application according to peak level that the peak level or drip tray that this is indicated can accommodate when peak level
Peak level L.
Step 300, if so, determining that the drip tray by foreign matters from being blocked, controls air-conditioner set and shuts down；
By 2/3 as judge whether be foreign matters from being blocked condition, determine according to the actual situation, what is normally handled
In the process, general water level does not exceed the 2/3 of peak level, therefore is used as Rule of judgment for 2/3；If the numerical value is too low,
It is possible that often assert that drip tray by foreign matters from being blocked, and then reports failure, but failure is reported caused by this numerical value is too low, had
Very maximum probability can be wrong report, and this reduces the accuracys of judgement, influence the using effect of user；If the numerical value is excessively high,
It may occur after reporting failure, have little time reparation etc. and cause the case where water level goes up to peak level and overflows in drip tray, make
At building damage, the using effect of user is influenced.
Step 400, if it is not, then judging whether the drip tray water level is greater than the second watermark threshold；
Wherein, the value range of second watermark threshold be 0.4L-0.6L, wherein L indicate drip tray can contain or
The peak level of receiving, it is specific as described above.If the value of the second watermark threshold is excessively high, failure was easily occurred in later not
And repair, so that water level continues to go up, drip tray is overflowed, building damage is caused；If value is too low, it is easy to appear and often recognizes
To be to break down, very maximum probability can be wrong report, just reduce the accuracy of judgement, influence the using effect of user.
Preferably, the value range of second watermark threshold be 1/2L, in this way, will not both generate maximum probability wrong report or
Person frequently reports the case where failure, will not be in report failure later not as good as repairing, so that overflowing drip tray or exceeding the first water level
Threshold value leads to the case where directly shutting down, to improve the experience effect of user.
Step 500, if so, according to inner disc temperature and drip tray temperature, control air-conditioner set progress ice operation.
It, can be in this way, whether can be judged by foreign matters from being blocked by the water level of drip tray drip tray water draining beak
The water freezing blocking that whether is condensed of drip tray water draining beak is judged by drip tray water level and temperature, so as to go out
When existing condensed water ice blockage water draining beak and foreign matters from being blocked water draining beak, determines in time or find, and then take shutdown or change
The corresponding measure such as ice, prevents the consequences such as the leak as caused by can not drain, and improves using effect and the user of air-conditioner set
Experience.
Further, as shown in connection with fig. 2, in the drip tray fault detection and control method, after the step 500, packet
It includes:
Step 600, after the first preset time, judge whether the drip tray water level is less than or equal to the second water level threshold
Value；
Wherein, first preset time determines according to actual conditions, can be grasped for the air-conditioner set progress ice
The time of work in other words after the operation of air-conditioner set completionization ice, then judges whether the drip tray water level is less than or equal to institute
The second watermark threshold is stated, in this way, the effect that can be operated to air-conditioner set ice judges, to judge whether drip tray blocks up
The reason of plug and drip tray block is foreign matters from being blocked or ice blockage；Wherein, first preset time may be tool
The period of body, which is more than or equal to the time of air-conditioner set progress ice operation, this way it is not necessary to right
Whether the operation of completion ice is judged air-conditioner set, directly can judge drip tray water level again by determining on the time
On opportunity, on the basis of so as to judge in the effect that can be operated to air-conditioner set ice, simple flow step is saved
Judge the time；Wherein, first preset time may be other specific periods, and value can be 20min-
30min prevents the air-conditioning as caused by frequently determining in this way, can be defined to the frequency of drip tray water level is judged again
Unit frequent switching, or as determining that inaccuracy is judged not in time or judged caused by the frequency is too low, improve the efficiency of judgement
And accuracy.
Preferably, first preset time is 25min.
Step 700, if it is not, then adding up primaryization ice number of operations, and judge whether describedization ice number of operations is greater than three
It is secondary；
If the drip tray water level is greater than second watermark threshold, it may be considered that being the operation of air-conditioner set progress ice
And it is unsuccessful, among these being likely to be ice be not thorough or the too fast causedization ice of icing rate after regelation, also have
May be ice is smooth, but the blocking of drip tray water draining beak fails caused by improvement；Therefore the number for changing ice operation is carried out
It is accumulative, accurately determined in order to subsequent.
Step 800, if describedization ice number of operations is greater than three times, determine that the drip tray by foreign matters from being blocked, resets institute
Stating ice number of operations, and control the air-conditioner set and shut down；
If describedization ice number of operations is greater than three times, it may be considered that being by the way that continuously air-conditioner set progress ice is grasped three times
Make, not can solve the blockage problem of drip tray water draining beak, blocked if it is caused by icing, pass through air conditioner continuously three times
The operation of groupization ice can be obviously improved its blockage problem, therefore be more than three times, it may be considered that drip tray water draining beak is not knot
Blockage problem caused by ice that is to say foreign matters from being blocked water draining beak；In this way, by sentencing later to the accumulative of change ice number of operations
It is fixed, eliminate single ice operating trouble, icing rate it is fast etc. caused by erroneous judgement so that the judgement to foreign matters from being blocked is more quasi-
Really, it is targetedly operated so as to provide, overflows damage building to avoid condensed water caused by foreign matters from being blocked, further mention
The experience of high user.
Step 500, if describedization ice number of operations is less than or equal to three times, according to the inner disc temperature and the drip tray
Temperature controls the air-conditioner set progress ice operation.
Describedization ice number of operations is less than or equal to three times, and drip tray water level does not drop to home, it is likely that single
Caused by secondaryization ice operating trouble, icing rate are fast etc., therefore repeat air-conditioner set progress ice and operate, thus reduce because
The blocking of water draining beak caused by icing.
In this way, it is accumulative by continuous change ice operation three times, wrong report foreign matters from being blocked can be prevented, if continuous water receiving three times
Disk can not still empty water, it is understood that there may be factor be drip tray because foreign matter causes dirty stifled, non-icing reason causes, or freezes
It is especially thick, it can not be eliminated and be blocked by the operation of air-conditioner set itself, at this point, foreign matters from being blocked can also be regarded as, into
Row reports failure, so as to effectively remind user to check the situation in drip tray, reaches and user is reminded to remove blocking or temporary
It stops using, prevents condensed water from overflowing drip tray.
Further, as shown in connection with fig. 3, in the drip tray fault detection and control method, the step 500, according to
The inner disc temperature and the drip tray temperature control the air-conditioner set progress ice operation, comprising:
Step 510, the inner disc temperature and the drip tray temperature of the air-conditioner set are obtained；
It can be obtained by the temperature sensor 3 being arranged in air-conditioner set and the temperature sensor 3 being arranged on drip tray
Take inner disc temperature and drip tray temperature；Consequently facilitating subsequent judgement.
Step 520, judge the drip tray temperature whether less than 0 DEG C；
Drip tray temperature then has begun accumulated ice, it is stifled that accumulated ice situation will lead to drip tray water draining beak less than 0 DEG C in drip tray
Plug.
Step 530, if so, judging whether the duration of the drip tray temperature less than 0 DEG C is greater than first time threshold
Value；
Wherein, the value range of the first time threshold is 0.5min-2min；In this way, passing through setting first time threshold
Value can prevent the temperature sensor 3 as caused by sensor fault or other external causes interference (as cold air brushes) from measuring
Mistake, to improve the accuracy of judgement.
Preferably, the first time threshold is 1min；In this way, both (can be handled to drip tray accumulated ice in time
One time threshold is excessive, can drag judgement and processing slowly to drip tray accumulated ice situation), it is also possible to prevent by external cause or sensor
The interference of failure improves the accuracy of judgement.
Step 540, if the duration is greater than the first time threshold, determine that drip tray freezes, described in control
Air-conditioner set carries out the operation operation of drip tray ice.
In this way, drip tray accumulated ice situation is judged by the drip tray temperature, by the way that first time threshold is arranged,
Prevent from interfering due to sensor fault or other external causes, improve the accuracy of judgement, thus the case where freezing to drip tray into
Row determines, with the operation of taking ice in time.
Further, as shown in connection with fig. 4, the step 500 further include:
Step 550, if the drip tray temperature is not less than 0 DEG C, judge the inner disc temperature whether less than 0 DEG C；
Wherein, the condensed water that drip tray contains is dripped from evaporator, if the temperature of drip tray is lower than 0 DEG C,
Drip tray can freeze；If the temperature (that is to say inner disc temperature) of evaporator is lower than 0 DEG C, evaporator may freeze, this meeting
The condensed water for causing condensed water to be difficult to drip or drip is easy to the accumulated ice on drip tray, and then blocks condensate water discharging mouth,
Thus need to judge inner disc temperature.
Step 560, if the inner disc temperature is less than 0 DEG C, whether judge the duration of the inner disc temperature less than 0 DEG C
Greater than the first time threshold；
Wherein, the value range of the first time threshold is 0.5min-2min；In this way, passing through setting first time threshold
Value can prevent the temperature sensor 3 as caused by sensor fault or other external causes interference (as cold air brushes) from measuring
Mistake, to improve the accuracy of judgement.
Preferably, the first time threshold is 1min；In this way, both (the can be handled to evaporator icing in time
One time threshold is excessive, can drag judgement and processing slowly to drip tray accumulated ice situation), it is also possible to prevent by external cause or sensor
The interference of failure improves the accuracy of judgement.
Step 570, it if so, determining that evaporator freezes, controls the air-conditioner set and is evaporated the operation operation of device ice.
In this way, being judged by the inner disc temperature evaporator ice condition, by the way that first time threshold is arranged, prevent
Only since sensor fault or other external causes interfere, the accuracy of judgement is improved, so that the case where freezing to evaporator carries out
Determine, with the operation of taking ice in time.
Wherein, why first drip tray temperature is judged, only in the case where drip tray temperature is greater than 0 DEG C,
It goes to judge inner disc temperature, is to operate the method operated with drip tray ice by evaporator ice to determine；In the application,
Due to can not be directly to drip tray progress ice, so being to influence drip tray by improving the temperature of evaporator, to dock
Water pond progress ice, therefore, will be when to drip tray progress ice as long as determining to be drip tray accumulated ice, while will evaporate
The icing of device removes (if evaporator also freezes) and therefore first judges drip tray temperature, so that changing ice behaviour
Make more convenient, quick.
In addition, if newly increased the mode of other drip tray ice, such as that heating tape is arranged on drip tray is independent
To the mode of drip tray ice, in above-mentioned judgement, first inner disc temperature can also be judged, be only greater than 0 in inner disc temperature
In the case where DEG C, just the temperature of drip tray is judged, or inner disc temperature and drip tray temperature are judged simultaneously, so
It freezes afterwards for drip tray and evaporator freezes while taking ice operates.
Further, as shown in connection with fig. 5, the step 570, comprising:
Step 571, it controls outer blower and compressor is out of service, and record outer fan parking duration；
Step 572, control inner blower brings into operation；
It wherein, be to evaporator progress ice, due to having anti-freeze function, institute to evaporator in existing air-conditioner set
Even if will not be ice of great thickness, under normal circumstances, evaporator is frosting, only more special with evaporator icing
In the case of, Cai Huijie very thin ice, therefore in evaporator ice, do not need additional heating movement, it is only necessary to by outside
Wind (temperature outside is generally higher than 0 DEG C) directly brush on evaporator can, therefore, stop outer blower and compressor,
Only allow inner blower, that is, can reach extraneous wind and directly brush the purpose of evaporator, to be evaporated device ice.
Step 573, judge whether the outer fan parking duration be greater than second time threshold and the inner disc temperature
Greater than the first temperature threshold；
Wherein, the value range of the second time threshold is 2min-5min；In this way, the shutdown of compressor can be made
Duration (compressor and outer blower are simultaneously stopped, therefore the shutdown duration of outer blower is also the shutdown duration of compressor) is longer, prevents
Only compressor is damaged due to frequently stopping machine.
Preferably, the second time threshold is 3min or 4min；In this way, compressor can be made to guarantee air conditioner
High-low pressure in group just starts to start after restoring balance, to prevent the damage caused by compressor of high-low pressure imbalance.
Wherein, the value range of first temperature threshold is 5 DEG C -10 DEG C；In this way, can judge to steam by inner disc temperature
Whether hair device changes ice completion, and accuracy is high.
Preferably, first temperature threshold is 7 DEG C, in this way, the accuracy of judgement is higher.
Step 574, if outer fan parking duration is greater than second time threshold and the inner disc temperature is greater than the first temperature threshold
Value, then judge whether the inner disc temperature is greater than third time threshold greater than the duration of the first temperature threshold；
Wherein, the third time threshold be 5s-20s, in this way, by setting third time threshold, can prevent due to
3 measuring error of temperature sensor caused by sensor fault or other external causes interference (as outside air brushes), to improve
The accuracy of judgement；Evaporator ice condition condition can also be determined in time, to improve the efficiency of evaporator ice operation (when third
Between threshold value it is excessive, judgement and processing slowly to evaporator ice condition condition can be dragged).
Preferably, the third time threshold is 10s；In this way, further increasing the accuracy of judgement and changing ice operation
Timeliness.
Step 575, it if the duration is greater than third time threshold, controls the air-conditioner set and is switched to refrigeration mould
Formula.
In this way, outside air is brushed by evaporator by operation inner blower, so that evaporator progress ice is operated, and
