Specific embodiment
The present embodiment provides firstly a kind of air-conditioner control method, and Fig. 1 is air-conditioning according to an embodiment of the invention
The schematic diagram of device control method.
As shown in Figure 1, the air-conditioner control method of the present embodiment includes:
S102, the operational mode after being switched on according to air conditioner send a VSP to the indoor unit blower of air conditioner and identify voltage；
S104 obtains the operational mode of the corresponding air conditioner of VSP identification voltage；
S106 judges that whether dirty the filter screen of air conditioner is stifled according to operational mode.
Generally, by detecting indoor unit blower current value, judge that whether dirty filter screen is stifled according to blower current value, it is former
Reason is: in the process of running, the filter screen that wind first passes through indoor unit air inlet enters in the indoor unit of air conditioner air-conditioning, and changes
It is sent out again by blower after hot device heat exchange.When filter screen dirtying blocks up, valid circulation area can be reduced, the incoming air area of air conditioner
It will correspondingly reduce, correspondingly, air quantity can be reduced to certain degree.
For the blower of the same indoor unit, air quantity is exactly its load, and then load is big greatly for air quantity, and air quantity is small, loads
It is small, and load directly proportional to electric current.If filter screen dirtying is stifled, air quantity decline, blower current value reduces, therefore, blower current value
There are certain corresponding relationships with the dirty stifled situation of strainer, by detection blower fan electric current, can determine whether filter screen according to blower current value
Dirty stifled situation.
However, temperature and density can occur after the indoor heat exchanger heat exchange that the air for entering the room machine passes through air conditioner
Variation causes blower rotation load also to will appear difference, and therefore, air conditioner refrigeration, heating operation can generate not blower electric current
Same influence, when that is to say refrigeration mode and heating mode, filter screen dirtying is stifled to determine that situation is different, need to determine that first air conditioner is opened
Operational mode when machine, then be filtered the dirty stifled situation of net and determine.
Existing fan control module is the tach signal for receiving blower feedback, provides driving voltage, but wind for blower
Machine control module can not know operating modes of air conditioner, therefore, in the operational mode for obtaining the corresponding air conditioner of VSP identification voltage
Before, the corresponding relationship of VSP identification voltage and operating modes of air conditioner should be first established, then searches the VSP from the corresponding relationship
Identify the corresponding operational mode of voltage.In other words, it needs pre- between fan control module and air conditioner booting control module
If an identification voltage corresponding with operational mode, for example, the corresponding identification voltage of heating mode is 5v, refrigeration mode is corresponding
Identification voltage is 6v.
When air conditioner is switched on, operational mode when air conditioner is switched on control module according to booting is sent to fan control module
One VSP identifies voltage, and fan control module determines the operational mode of air conditioner according to the identification voltage, later further according to the operation
Mode is filtered the judgement for netting dirty stifled situation.
When refrigeration mode, air conditioner booting, wind deflector is opened, and wind deflector is opened to setting position, and blower is opened, at this time
It is filtered the judgement for netting dirty stifled situation.When due to refrigeration, after air conditioner booting, blower is turned on quickly, indoor heat exchanger
Temperature is not yet substantially reduced, with indoor heat exchanger heat exchange after air-flow temperature and indoor environment in air themperature difference compared with
Small, the load of blower can be approximately corresponding under current environmental temperature by blower air.
And when heating mode, since heating has anti-cool wind mode, when air conditioner is switched on, blower is simultaneously not turned on, but is waited
When indoor heat exchanger coil temperature is increased to certain numerical value, for example, blower is just opened at 25 DEG C, then it is filtered the dirty stifled feelings of net
The judgement of condition differs greatly at this point, indoor heat exchanger coil temperature has built up with indoor environment temperature, and the load of blower is answered
Corresponding to the air for passing through blower at a temperature of current indoor heat exchanger coils.
Specifically, the filter screen detailed process whether dirty plugging of air conditioner is judged according to operational mode are as follows:
If the operational mode of air conditioner is refrigeration mode, indoor unit blower is opened；
The environment temperature in space where detecting indoor unit, and the electric current of detection blower fan, obtain the first current value；
It obtains the corresponding filter screen dirtying of current environmental temperature and blocks up predetermined current, be denoted as the first pre-set current value；
First current value is compared with the first pre-set current value, if the first current value is less than or equal to the first default electricity
Flow valuve then determines that filter screen dirtying is stifled.
As previously mentioned, blower current value will receive the influence of operating modes of air conditioner, when refrigeration mode, fans load is corresponding
Pass through the air of blower under current environmental temperature, therefore, at a temperature of experiment collection varying environment should be first passed through, the filtering of blower
Dirty stifled predetermined current is netted, the filter screen dirtying of the environment temperature in space and indoor unit blower where establishing indoor unit blocks up predetermined current
Corresponding relationship.
When air conditioner in actual use, when opening operation in a chiller mode, then where the indoor unit space environment
Temperature and the filter screen dirtying of indoor unit blower, which block up in the corresponding relationship of predetermined current, searches the corresponding filtering of current environment temperature
Dirty stifled predetermined current is netted, and the filter screen dirtying is blocked up into predetermined current and is compared with the blower electric current of current detection, therefore, it is determined that
Filter screen dirtying blocks up situation.
When heating mode, the decision process that the filter screen dirtying of air conditioner blocks up situation is specifically included:
If operating modes of air conditioner is heating mode, the indoor heat exchanger coil temperature of air conditioner is detected；
When heat exchanger coils temperature is greater than heat exchanger coils preset temperature, indoor unit blower is opened；
The electric current of indoor unit blower is detected, the second current value is obtained；
It obtains the corresponding filter screen dirtying of heat exchanger coils temperature and blocks up predetermined current, be denoted as the second pre-set current value；
Second current value is compared with the second pre-set current value, if the second current value is less than or equal to the second default electricity
Flow valuve then determines that filter screen dirtying is stifled.
As previously mentioned, when heating mode, fans load corresponds at a temperature of current heat exchanger coils the air for passing through blower,
Therefore, experiment should be first passed through to collect under various heat exchange device coil temperature, the filter screen dirtying of blower blocks up predetermined current, establishes heat exchanger
The filter screen dirtying of coil temperature and indoor unit blower blocks up the corresponding relationship of predetermined current.
In the prior art, in the experiment for obtaining the stifled predetermined current of filter screen dirtying, indoor unit is not freezed or is made
Heat is only to open indoor unit blower, and indoor air enters the room machine by the dirty stifled strainer of air inlet, then passes through detection
The electric current of blower determines that filter screen dirtying blocks up predetermined current, and the acquisition which blocks up predetermined current does not account for air conditioner reality
In the heating operation of border, heat exchanger coils temperature and environment temperature difference and caused by blower current detecting deviation, easily cause to miss
Sentence.
And in the present embodiment, in obtaining the experiment for filtering dirty stifled predetermined current, indoor unit is run with heating mode, is obtained
The filter screen dirtying of corresponding indoor unit blower blocks up predetermined current under various heat exchange device coil temperature, establishes heat exchanger coils temperature with this
Degree blocks up the corresponding relationship of predetermined current with the filter screen dirtying of indoor unit blower.In the practical heating operation of air conditioner, work as indoor unit
When blower is opened, searches and work as from the corresponding relationship that the filter screen dirtying of heat exchanger coils temperature and indoor unit blower blocks up predetermined current
The preceding corresponding filter screen dirtying of heat exchanger coils temperature blocks up predetermined current, which is blocked up the current of predetermined current and detection
The electric current of indoor unit blower is compared, so as to accurately determine that whether dirty filter screen is stifled.
When filter screen dirtying blocks up electric current of the predetermined current less than the indoor unit blower of current detection, determine that filter screen dirtying is stifled,
Meanwhile it can be filtered the operation of net cleaning reminder, for example, to the user terminal output filter screen cleaning bound in advance with air conditioner
Prompt information.
In some embodiments, the control method of air conditioner may also include the accumulated time of record indoor unit operation.Logical
It crosses after the above process determines that filter screen dirtying is stifled, it is pre- can to judge whether the accumulated time of indoor unit operation is equal to or more than second again
If the time, if accumulated time is greater than the second preset time, it is filtered the operation of net cleaning reminder.In the present embodiment, by blower
Electric current determine and indoor unit operation accumulated time be combined, can more accurately determine remind user cleaning filter screen when
Machine.
