Embodiment

In the following detailed description, a large amount of specific details are proposed, in order to provide thorough understanding of the present invention.But, It will be understood by those within the art that can also implement the present invention even if without these specific details.In other cases, without detailed Well-known method, process, component and circuit are carefully described, in order to avoid influence the understanding of the present invention.

For the ease of understanding the illustrative embodiment in the present invention faster, letter is carried out to the main thought of the present invention at this Unitary declaration:

In the prior art, during air conditioner cooling condition is run, the surface of heat exchanger can accumulate dust and dirt, these dirt Dirty on the one hand to reduce the heat exchange property of heat exchanger, on the other hand easily breed bacteria, formation spot are mould, these bacteriums and the mould meeting of spot Peculiar smell is produced in device.In the prior art when air conditioner is freezed or dehumidify operating when, its internal heat exchanger is used as evaporation Device is used, and heat exchanger is reduced the surface temperature of heat exchanger by the heat transfer of refrigerant, and now the vapor in indoor set can quilt Aqueous water (i.e. condensed water) is condensed into, the condensed water of formation can adhere to the part surface of heat exchanger, be affected by gravity, to flowing down It is dynamic, it is collected by the drip tray for being arranged on heat exchanger bottom.But the above method is for the surface cleaning and inequality of heat exchanger It is even, and the condensed water that may also be resulted in is not enough, and carry out when heating and blowing operation, indoor heat exchanger can not be produced Raw condensed water, causing the dust and dirt of heat exchanger surface can not be eliminated.

Embodiment 1

The present invention passes through environment temperature and ambient humidity by influenceing every influence factor of condensed water formation to be analyzed Determine that heat exchanger is used for the Optimal Temperature of condensed steam under the present circumstances in itself, then with the rotating speed of the blower fan to indoor set Regulation, realizes the heating and cooling of heat exchanger, the actual temperature of heat exchanger is maintained to the Optimal Temperature analyzed, enough to be formed Condensed water ensures the cleaning effect of the dust and dirt on heat exchanging device surface, and minimum energy consumption, accomplishes to save energy resources.

Referring now to Fig. 1, Fig. 1 shows that a kind of adjusted based on wind speed collects the flow chart that condensed water cleans air conditioner.

As shown in figure 1, a kind of method for being adjusted based on wind speed and collecting condensed water cleaning air conditioner is disclosed, including:Utilize Water vapor condensation in air conditioner into aqueous water, will be attached to the dirt on the surface of the heat exchanger by the heat exchanger in air conditioner Remove, in the process, in addition to:

S11, according to the current environment temperature of the air conditioner and ambient humidity, determine the heat exchanger for condensed water steam The surface temperature of gas, is used as preferred temperature;

Wherein, ambient humidity is the relative humidity detected, and the preferred temperature determined can be a temperature spot such as x DEG C or a temperature range such as [y DEG C, z DEG C], y<z.

S12, the rotating speed by adjusting the blower fan in the air conditioner, by the temperature adjustment of the heat exchanger and maintain institute State preferred temperature.

Wherein, by monitoring the current actual temperature of heat exchanger in real time during being somebody's turn to do, two regulation strategies, one can be included It is the regulation in the case that the actual temperature detected is more than preferred temperature, makes the temperature drop of heat exchanger, two is when monitoring The actual temperature gone out is less than the regulation in the case of preferred temperature, raises the temperature of heat exchanger;Furthermore it is also possible to including the 3rd Individual regulation strategy, i.e., the actual temperature that ought be detected meets the regulation in the case of the requirement of preferred temperature, makes the temperature of heat exchanger Degree remains unchanged.

Influence of the present invention by analysis environments temperature and ambient humidity to dew point, determines that heat exchanger is most under current environment Good temperature, to obtain the dust and dirt that the condensed water of sufficient amount removes heat exchanger surface.And in the actual temperature and optimal temperature of heat exchanger When degree is not inconsistent, using the regulation to rotation speed of fan, rising or falling for heat exchanging device temperature is realized, the temperature of heat exchanger is maintained It is determined that optimum temperature, reach automated cleaning and the automatic adjusument of heat exchanger, and ensure that heat exchanger cleaning effect Really.

The signified dew-point temperature in some illustrative embodiments in the present invention refers under current environment in air conditioner Vapor is converted to the temperature required for aqueous water.Due to reasons such as the pressure size in environment, temperature level, humidity sizes Cause the difference of dew-point temperature, it is therefore desirable to analysis determination is carried out to the dew-point temperature under current environment, in addition, for user Atmospheric pressure in speech, its surrounding air is relatively stable, therefore is mainly environment temperature and environment for the influence of dew-point temperature Both humidity.

In some illustrative embodiments, according to the current environment temperature of air conditioner and ambient humidity, the heat exchange is determined The preferred temperature of device, is specifically included:

S21, according to the current environment temperature of air conditioner and ambient humidity, analyze the dew-point temperature under current environment;

7. clean method according to claim 5, it is characterised in that it is described according to the air conditioner under heating condition Cleaning procedure described in handling strategy execution, is specifically included:
The air conditioner is switched into cooling condition, using the heat exchanger in air conditioner by the water vapor condensation in air conditioner into liquid State water, will be attached to the dirt removal on the surface of the heat exchanger.
8. clean method according to claim 4, it is characterised in that according to processing of the air conditioner under cooling condition Cleaning procedure described in strategy execution, is specifically included:
Perform following at least one times operate:
Perform the cleaning procedure operation first time period, then normal refrigerating operaton second time period.
9. a kind of adjusted based on wind speed collects the device that condensed water cleans air conditioner, based on using the heat exchanger in air conditioner by sky Adjust the water vapor condensation in device into aqueous water, will be attached to the dirt removal on the surface of the heat exchanger, including:
Judge module, the trigger condition of the cleaning procedure is performed for judging whether the air conditioner meets;
Cleaning module, for when meeting the trigger condition, according to the current operating condition of the air conditioner according to the fortune Cleaning procedure described in the corresponding processing strategy execution of row operating mode;Wherein described cleaning module includes:
Parsing module, including:
First analyzing sub-module, according to the current environment temperature of the air conditioner and ambient humidity, is analyzed under current environment Dew-point temperature;With
Second analyzing sub-module, for the dew-point temperature to analyze, determine the heat exchanger be used for condense expectation temperature Degree;
Adjustment module, by adjusting the rotating speed of the blower fan in the air conditioner and/or the working frequency of compressor, by the heat exchange The temperature adjustment of device simultaneously maintains the preferred temperature;And second analyzing sub-module determines the expectation according to equation below Temperature:
Teva=t- Δs t
Wherein, the Teva is the preferred temperature of the heat exchanger, and t is dew-point temperature, and Δ t is the phase of dew-point temperature and heat exchanger Hope the temperature difference.
