Specific embodiment

In order to make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to drawings and examples, Invention is further described in detail.

Referring to Figure 1, which show the flow chart of the clean method one embodiment of the air condition of that present invention intelligent self-cleaning.

As shown in Figure 1, the embodiment realizes that the process of the clean method of air conditioner intelligent self-cleaning includes the following steps:

Step 11: judging whether air conditioner meets the entry condition for executing automatically cleaning processing.

Wherein, the entry condition for meeting execution automatically cleaning processing includes two, first entry condition are as follows: while meeting room The condition of interior someone, the accumulated running time of air conditioner are greater than the condition of setting accumulated running time threshold value, indoor environment temperature Condition, indoor environment humidity greater than set environment temperature are greater than the condition of set environment humidity and air conditioner is in shutdown shape The condition of state;Second entry condition are as follows: at the same meet indoor nobody condition within the setting duration, air conditioner it is accumulative Runing time is greater than the condition for setting accumulated running time threshold value and air conditioner is in the condition of off-mode.

That is, only have while meeting five conditions in first entry condition, or second is met simultaneously and is opened Three conditions in dynamic condition just determine it is to meet the entry condition for executing automatically cleaning processing.

With the development of Cloud Server technology and intelligent air conditioner technology, above-mentioned multiple conditions can pass through intellectual technology It realizes, participation without user.Wherein, the accumulated running time of air conditioner can be taken by the cloud of air conditioner intelligent link Business device take statistics and obtain to the runing time of air conditioner, indoor environment temperature can by Cloud Server by setting indoors, The output signal of the temperature sensor of temperature detection signal is connect and can uploaded with Cloud Server and is obtained, and indoor environment humidity can With by Cloud Server by setting indoors, with Cloud Server connect and can upload Humidity Detection signal humidity sensor it is defeated Out signal and obtain, air conditioner off-mode can also obtain the monitoring of conditioners running conditions by Cloud Server, and It is indoor whether the monitoring of someone can by Cloud Server by setting indoors, connect simultaneously energy uploading detection signal with Cloud Server Touching sensor output signal and obtain.Therefore, Cloud Server get with can be convenient it is indoor whether someone, air conditioner Accumulated running time, indoor environment temperature, indoor environment humidity and air conditioner off-mode.So, by cloud service Setting accumulated running time threshold value, setting duration, set environment temperature and set environment humidity, cloud clothes are stored in advance in device Business device can determine whether to meet all Rule of judgment in one of entry condition simultaneously at any time, and determine to meet certain Confirmation meets the entry condition for executing automatically cleaning processing when one entry condition.

Can be a fixed value also, for setting runing time threshold value, preferably can it is different according to season or The current operating condition of air conditioner and the value of adaptive change.For example, if winter or heating operation operating condition, when setting is run Between threshold value value be the first runing time threshold value, and if summer or refrigerating operaton operating condition, set runing time threshold value value For the second runing time threshold value, and the first runing time threshold value is less than the second runing time threshold value.

For set environment temperature, it is contemplated that user's comfort, preferably 20 DEG C.

For set environment humidity, refer to relative humidity, it is contemplated that the formation humidity requirement of condensed water, preferably 40%.

And for setting the duration, error is monitored to reduce, preferably 30min.

Step 12: if satisfied, air conditioner opens automatically cleaning processing function, executing the automatically cleaning processing of heat exchanger.

That is, meeting the condition of indoor someone at the same time, the accumulated running time of air conditioner is greater than the accumulative operation of setting It is wet greater than set environment that the condition of time threshold, indoor environment temperature are greater than the condition of set environment temperature, indoor environment humidity The condition and air conditioner of degree are in the entry condition that the condition of off-mode this five conditions are constituted, alternatively, same When meet it is indoor when the accumulated running time for setting nobody condition in the duration, air conditioner being greater than the accumulative operation of setting Between threshold value condition and in the case that air conditioner is in the entry condition that the condition of off-mode is constituted, determine to meet The entry condition for executing automatically cleaning processing then controls air conditioner and automatically turns on automatically cleaning processing function, executes the certainly clear of heat exchanger Clean processing.

Wherein, the process for executing the automatically cleaning processing of heat exchanger can be realized using the method for the prior art.As excellent The embodiment of choosing, using Fig. 2 shows detailed process realize, be detailed in the description below to Fig. 2.

In this embodiment, in the entry condition for executing automatically cleaning processing, it is indoor within the setting duration nobody The personnel state of current indoor is reflected, the accumulated running time of air conditioner reflects the dust accumulation degree of heat exchanger in air conditioner, The size of indoor environment temperature reflects the level of comfort of current indoor temperature, the size of indoor environment humidity reflect to be formed it is cold The complexity and water of condensate, and the off-mode of air conditioner reflects user to the operation demand situation of air conditioner.So, It, can be in heat exchanger product using judgement relationship above-mentioned as Rule of judgment by judging parameter using these parameters as condition There are dust and dirt, indoor someone but just execute in the case that indoor environment temperature and humidity are higher and air conditioner is not used by a user to change The automatically cleaning of hot device is handled, alternatively, just in the case where heat exchanger product has dust and dirt, indoor nobody and air conditioner are not used by a user The automatically cleaning processing of heat exchanger is executed, and entire deterministic process and automatically cleaning treatment process fully automated can be realized, without using Participation processing in family had both avoided without automatically cleaning and had blindly executed energy consumption problem caused by automatically cleaning is handled, also effectively prevented Air conditioner is because execution automatically cleaning processing causes room temperature uncomfortable and influences air conditioner because executing automatically cleaning treatment process Normal course of operation and the problem of influence user's comfortable sexual experience, both improved air conditioner properties of product and intelligence degree, Improve the user satisfaction and convenience of user.

Moreover, then air conditioner is protected in a step 11 if it is determined that air conditioner is unsatisfactory for executing the entry condition of automatically cleaning processing Former working condition is held not change.

As preferred embodiment, during executing automatically cleaning processing, once indoor someone is monitored, then automatically Exit automatically cleaning treatment process.Also, if automatically cleaning treatment process has been not carried out and has interrupted, meet the starting of step 11 again When condition, automatically cleaning processing is reentered again.

Fig. 2 is referred to, which show the specific flow chart that the automatically cleaning processing of heat exchanger is executed in Fig. 1.

As shown in Fig. 2, the embodiment realizes that the process of the automatically cleaning processing of heat exchanger includes the following steps:

Step 121: determining the current operating condition of air conditioner, held according to processing strategie corresponding with current operating condition Row self-cleaning program.

Specifically, being the operating condition for determining that air conditioner is current, according to processing plan corresponding with current operating condition Self-cleaning program is slightly executed, the vapor in air conditioner is condensed into liquid water using the heat exchanger in air conditioner, utilizes liquid Water heat exchanging device carries out automatically cleaning processing.

Wherein, the current operating condition of air conditioner can be cooling condition, heating condition, air-supply operating condition and dehumidifying Operating condition etc..The current operating condition of air conditioner can pass through indoor/outdoor environment temperature, indoor/outdoor ambient humidity etc. The corresponding relationship of parameter and known parameter and operating condition and obtain.Communication based on intelligent air-conditioning and Cloud Server, when Preceding operating condition can be monitored and be obtained by Cloud Server.Based on this, automatically cleaning processing function, execution are opened in air conditioner When the automatically cleaning processing of heat exchanger, the current operating condition of air conditioner is determined first, different operating conditions is carried out respectively Corresponding cleaning strategy, to guarantee the cleaning effect for being satisfied with different operating conditions.

For example, if it is decided that the current operating condition of air conditioner is heating condition, executes the strategy of automatically cleaning processing Are as follows: operating modes of air conditioner is switched into refrigeration mode operation, and controls runing time and is no less than the first setting runing time, benefit The vapor in air conditioner is condensed into liquid water with the heat exchanger in air conditioner, is carried out certainly using the liquid water heat exchanging device Cleaning treatment.Moreover, because air conditioner normal operation mode is heating mode under heating condition, for the heat exchange in indoor unit For device, it is condenser, condensed water will not be generated, thus, it not will do it automatically cleaning in a heating mode.Therefore, the first setting Runing time is a longer time value, and when executing automatically cleaning processing, control runing time is longer, so as to in indoor unit Heat exchanger execute long-time, thoroughly automatically cleaning.

If it is determined that the current operating condition of air conditioner is cooling condition, the strategy of automatically cleaning processing is executed are as follows: air conditioner Refrigeration mode is run, and runing time is controlled and is no less than the second setting runing time, using the heat exchanger in air conditioner by air-conditioning Vapor in device is condensed into liquid water, carries out automatically cleaning processing using liquid water heat exchanging device.Due to empty under cooling condition Adjusting device normal operation mode is refrigeration mode or dehumidification mode, is evaporator, just for the heat exchanger in indoor unit Condensed water generation is had in normal operational process, therefore, it is possible to carry out part automatically cleaning.Therefore, second runing time is set to be small In a time value of the first setting runing time, when executing automatically cleaning processing, control runing time is shorter, can be with lower Power consumption realize more thorough automatically cleaning.

Self-cleaning program is executed according to processing strategie corresponding with current operating condition, can specifically use following step 122 and the process of step 123 realize.

Step 122: indoor current environmental temperature and current environment humidity where obtaining air conditioner determine that heat exchanger is used for The surface temperature of condensation and as target temperature.

Wherein, it is got in real time when current environmental temperature and current environment humidity refer to starting automatically cleaning processing routine Indoor environment temperature and indoor environment relative humidity;And the target determined according to current environmental temperature and current environment humidity Temperature can be a temperature spot, be also possible to a temperature range.

As preferred embodiment, first according to current environmental temperature and current environment humidity, determine under current environment Dew-point temperature;Then, according to the dew-point temperature under current environment determine heat exchanger for condensation target temperature.

Specifically, dew-point temperature refers to that the vapor under current environment in air conditioner is converted to temperature required for liquid water Degree.Cause dew-point temperature different due to pressure size, temperature level and humidity size in environment etc., it is therefore desirable to right Dew-point temperature under current environment carries out analysis determination.In addition, the atmospheric pressure in surrounding air is more for corresponding user Stablize, therefore, the principal element influenced on dew-point temperature is environment temperature and ambient humidity.Thus, as preferred embodiment party Formula, the dew-point temperature under current environment can be determined according to following formula: t=U(A+BT)+CT-D.In the formula, t is dew point Temperature, U are ambient humidity, and T is environment temperature, and A, B, C and D are respectively the first adjustment factor, the second adjustment factor, third adjusting Coefficient and the 4th adjustment factor.Preferably, the value model of the first adjustment factor A, the second adjustment factor B and third adjustment factor C It encloses for 0-1, to reduce calculating error.For example, the first adjustment factor A value is 0.198, the second adjustment factor B is 0.0017, the Three adjustment factor C are 0.84.And the value range of the 4th adjustment factor D is 15-25, for example, selecting 19.2.

After calculating dew-point temperature t, it is preferred to use following formula determines the target temperature under current environment: Teva= t-Δt.In the formula, Teva is target temperature, and t is dew-point temperature, and Δ t is the target temperature difference of dew-point temperature and heat exchanger.It is excellent Choosing, target temperature difference Δ t is setting value or matches acquisition in known heat transfer temperature difference table according to current environmental temperature.Consider To heat exchange situation under normal circumstances, the selection range of target temperature difference Δ t is 3-15 DEG C.Preferably, Δ t value is 8 DEG C.This It outside, can also be in such a way that heat transfer temperature difference table matches and obtains target temperature difference.In this case, being previously stored with environment temperature and mesh The correspondence table of the temperature difference is marked, for example, environment temperature is greater than 30 DEG C, and corresponding target temperature difference is 6 DEG C;Environment temperature is located at 20-30 DEG C In range, corresponding target temperature difference is 8 DEG C.So, the target temperature to match with current environmental temperature is found from corresponding table Difference, and assignment is in Δ t.

The dew-point temperature under current environment is determined by environment temperature and ambient humidity, then true with calculated dew-point temperature Determine heat exchanger for condensation surface temperature and as target temperature, it is ensured that the target temperature of acquisition is accurate and reliable, thus The automatically cleaning that enough condensed waters carry out heat exchanger can be obtained in a short time.

Step 123: by adjusting the revolving speed of the blower in air conditioner and/or the working frequency of compressor, by heat exchanger Temperature adjusts and maintains target temperature.

Wherein, which passes through the currently practical surface temperature of real-time monitoring heat exchanger, when the currently practical table detected When face temperature is greater than target temperature, by adjusting the revolving speed of blower and/or the working frequency of compressor, so that the surface of heat exchanger Temperature decline;When the currently practical surface temperature detected is less than target temperature, by the revolving speed and/or the compression that adjust blower The working frequency of machine, so that the surface temperature of heat exchanger increases;And when the currently practical surface temperature detected meets target temperature When spending, by adjusting the revolving speed of blower and/or the working frequency of compressor, so that the surface temperature of heat exchanger remains unchanged.

Therefore, using the adjusting of rotation speed of fan and/or compressor frequency, heat exchanger surface temperature is adjusted simultaneously in a short time Optimal target temperature is maintained, the quick self cleaning and adaptivity for reaching heat exchanger are adjusted, and ensure that the certainly clear of heat exchanger Clean effect.

Specifically, drop can be taken when the currently practical surface temperature of the heat exchanger detected is greater than target temperature The regulative mode of the working frequency of the revolving speed and/or promotion compressor of low blower, so that the surface temperature of heat exchanger declines.If prison When the currently practical surface temperature for the heat exchanger measured is less than target temperature, the revolving speed for promoting blower and/or reduction can be taken The regulative mode of the working frequency of compressor, so that the surface temperature of heat exchanger increases.And when the currently practical surface detected When temperature meets target temperature, maintains the current rotating speed of blower constant and/or maintain the present operating frequency of compressor constant.

By using above-mentioned adjusting, guarantee that air conditioner voluntarily completes the tune by the surface temperature of heat exchanger to target temperature It is whole, it realizes automatic adjustment, guarantees clean effect.

Using the automatically cleaning treatment process of above-described embodiment, is performed an analysis by influencing the factor that condensed water is formed, pass through reading Environment temperature and current environment humidity is taken to determine that heat exchanger itself is used for the Optimal Temperature of condensed steam under the present circumstances, then With the adjusting of rotation speed of fan and/or compressor operating frequency to indoor unit, the heating or cooling of heat exchanger are realized, by heat exchanger Actual surface temperature maintain determining Optimal Temperature, guarantee the dust and dirt on heat exchanging device surface to form enough condensed waters Clean effect is carried out, and realizes least energy consumption, accomplishes the energy conservation of air conditioner.

The above embodiments are merely illustrative of the technical solutions of the present invention, rather than is limited;Although referring to aforementioned reality Applying example, invention is explained in detail, for those of ordinary skill in the art, still can be to aforementioned implementation Technical solution documented by example is modified or equivalent replacement of some of the technical features;And these are modified or replace It changes, the spirit and scope for claimed technical solution of the invention that it does not separate the essence of the corresponding technical solution.
