[0044] As shown in Figures 1-5 The present application provides a filter screen dirty block monitoring method, which comprises:

[0045] S100, determining the actual temperature reaching time of the first indoor temperature regulated by the air conditioner to the first set temperature after the air conditioner is started.

[0046] Wherein, the first indoor temperature is the actual temperature of the current indoor environment, the first set temperature is the indoor target temperature that the user wants to regulate, and the actual temperature reaching time is the actual time of the first indoor temperature rising / dropping to the first set temperature.

[0047] S200, determining the theoretical temperature reaching time of the first indoor temperature regulated by the air conditioner to the first set temperature.

[0048] Wherein, the theoretical temperature reaching time is the theoretical time of the first indoor temperature rising / dropping to the first set temperature calculated according to the running parameters of the air conditioner and the like under the condition that the filter screen does not occur dirty block.

[0049] S300, determining that the filter screen occurs dirty block after determining that the actual temperature reaching time is greater than the theoretical temperature reaching time.

[0050] Wherein, since the theoretical temperature reaching time is the standard time of the actual indoor temperature rising to the target temperature under the condition that the filter screen of the air conditioner does not occur dirty block, when the actual temperature reaching time is greater than the theoretical temperature reaching time, it can be determined that the filter screen occurs dirty block at this time.

[0051] It can be understood that the above filter screen dirty block monitoring method determines the actual temperature reaching time of the air conditioner for adjusting the first indoor temperature to the first set temperature after the air conditioner is started, and determines the theoretical temperature reaching time of the air conditioner for adjusting the first indoor temperature to the first set temperature, and determines whether the filter screen is dirty and blocked according to the actual temperature reaching time and the theoretical temperature reaching time. After the actual temperature reaching time is greater than the theoretical temperature reaching time, it is determined that the filter screen is dirty and blocked, and then the dirty and blocked time of the filter screen is accurately determined according to different use environments.

[0052] In some embodiments, before determining that the actual temperature reaching time is greater than the theoretical temperature reaching time, the filter screen dirty block monitoring method further comprises:

[0053] determining a first difference value of the actual temperature reaching time and the theoretical temperature reaching time.

[0054] Wherein, the actual temperature reaching time is t 实际 , the theoretical temperature reaching time is t 理论 , and the first difference value is Δt1, wherein Δt1=t 实际 -t 理论 .

[0055] determining whether the first difference value is greater than a first preset value.

[0056] Wherein, the first preset value is data pre-stored in the controller of the air conditioner, and the first preset value is generally a positive number, so that there is a certain allowable error in the judgment of the actual temperature reaching time and the theoretical temperature reaching time. That is, in general, even in the case that the filter screen does not occur dirty and blocked, the actual temperature reaching time may be greater than the theoretical temperature reaching time, and will not be exactly equal to the theoretical temperature reaching time. Therefore, the first preset value is set to a positive number, allowing a certain allowable error between the actual temperature reaching time and the theoretical temperature reaching time.

[0057] When it is determined that the first difference value is greater than the first preset value, it is determined that the actual temperature reaching time is greater than the theoretical temperature reaching time.

[0058] Wherein, when the first difference value is greater than the first preset value, it means that the actual temperature reaching time has been greater than the theoretical temperature reaching time, and far exceeds the allowable deviation time, and then it can be determined that the actual temperature reaching time is greater than the theoretical temperature reaching time, that is, the filter screen is dirty and blocked.

[0059] In some embodiments, the filter screen dirty block monitoring method further comprises:

[0060] S400, determining a first temperature reaching time of the air conditioner for adjusting the first indoor temperature to the first set temperature when the filter screen reaches a set dirty block threshold.

[0061] Wherein, the dirty block threshold size represents the dirty block degree of the filter screen, and the set dirty block threshold is the degree of the filter screen when the dirty block alarm needs to be reminded by the air conditioner.

[0062] The first temperature-reach time is a temperature-reach time of the air conditioner for adjusting the indoor temperature from the first indoor temperature to the first set temperature when the filter screen is at a set threshold of the dirty degree, and since the filter screen has a certain degree of dirt, the cooling / heating capacity of the air conditioner is affected, thereby affecting the temperature-reach time.

[0063] The different dirty thresholds correspond to the dirty degrees of the filter screen, and correspond to different first temperature-reach times.

[0064] S500, after determining that the actual temperature-reach time is greater than or equal to the first temperature-reach time, it is determined that the dirty degree of the filter screen reaches the set dirty threshold, and a dirty alarm is performed.

[0065] When the actual temperature-reach time is greater than or equal to the first temperature-reach time, it is determined that the dirty degree of the filter screen reaches the condition that needs to be alarmed and reminded, and then the air conditioner is controlled to perform a dirty alarm.

[0066] In some embodiments, before determining that the actual temperature-reach time is greater than or equal to the first temperature-reach time, the filter screen dirty monitoring method further comprises:

[0067] Determining a second difference value between the actual temperature-reach time and the first temperature-reach time.

[0068] The actual temperature-reach time is t 实际 , the first temperature-reach time is t 脏堵 , and the second difference value is Δt2, where Δt2=t 实际 -t 脏堵 .

[0069] Determining whether the second difference value is greater than a second preset value.

[0070] The second preset value is data pre-stored in the controller of the air conditioner, and the second preset value is generally a positive number, so that there is a certain allowable error in the judgment of the actual temperature-reach time and the first temperature-reach time. That is, in some cases, due to other factors, the actual temperature-reach time is greater than the first temperature-reach time, but the actual dirty degree of the filter screen has not reached the dirty degree corresponding to the set dirty threshold, so the second preset value is set to a positive number, allowing the actual temperature-reach time and the first temperature-reach time to have a certain allowable error.

[0071] When the second difference value is greater than or equal to the second preset value, it is determined that the actual temperature-reach time is greater than or equal to the first temperature-reach time.

[0072] When the second difference value is greater than or equal to the second preset value, it means that the actual temperature-reach time is greater than or equal to the first temperature-reach time, and then it can be determined that the actual temperature-reach time is greater than or equal to the first temperature-reach time, that is, the dirty degree of the filter screen has reached the dirty degree corresponding to the set dirty threshold.

[0073] In some embodiments, S400, determining the first temperature-reach time of the air conditioner adjusting the first indoor temperature to the first set temperature when the filter screen reaches the set dirty block threshold, comprises:

[0074] S410, determining the dirty block cooling / heating capacity of the air conditioner when the filter screen reaches the set dirty block threshold.

[0075] Wherein, when the air conditioner is in heating mode, the dirty block heating capacity is determined; when the air conditioner is in cooling mode, the dirty block cooling capacity is determined.

[0076] Wherein, different dirty block thresholds represent different degrees of dirty block of the filter screen, and different degrees of dirty block of the filter screen have different degrees of influence on the cooling / heating capacity of the air conditioner, therefore, the set dirty block threshold has a corresponding dirty block cooling / heating capacity.

[0077] Wherein, the dirty block cooling / heating capacity corresponding to the set dirty block threshold can be determined by simulation software or preset parameters.

[0078] S420, determining the first temperature-reach time according to the dirty block cooling / heating capacity.

[0079] Wherein, determining the dirty block cooling / heating capacity of the air conditioner is essentially determining the specific influence of the dirty block of the filter screen of the air conditioner on the air intake of the air conditioner. Generally, the air intake directly affects the cooling / heating capacity of the air conditioner. After the dirty block of the filter screen of the air conditioner occurs, it directly affects the air intake of the air conditioner, and then affects the cooling / heating capacity of the air conditioner, thereby forming the dirty block cooling / heating capacity. After the dirty block cooling / heating capacity is determined, the first temperature-reach time can be determined according to the dirty block cooling / heating capacity, the temperature change and the indoor volume.

[0080] In some embodiments, S420, determining the first temperature-reach time according to the dirty block cooling / heating capacity, comprises:

[0081] Determining a first temperature difference according to the first indoor temperature and the first set temperature.

[0082] Wherein, the first indoor temperature is T 室1 , the first set temperature is T 设1 , the first temperature difference is ΔT1, and ΔT1=|T 室1 -T 设1 |.

[0083] Determining the first temperature-reach time according to the first temperature difference, the indoor volume and the dirty block cooling / heating capacity.

[0084] The indoor volume is generally the product of the indoor area and the indoor height of the current indoor environment.

[0085] The first temperature difference is ΔT1, the indoor volume is V, and the dirty-blocking refrigerating / cooling capacity is Q 脏堵 The first temperature-reaching time is t 脏堵 , The constant a is generally 0.86.

[0086] The constant a is generally the ratio of the dirty-blocking refrigerating / cooling capacity to the effective refrigerating / cooling capacity.

[0087] In some embodiments, S410, the dirty-blocking refrigerating / cooling capacity of the air conditioner when the filter screen reaches the set dirty-blocking threshold is determined, including:

[0088] S411, the attenuation ratio of the refrigerating / cooling capacity of the air conditioner when the filter screen reaches the set dirty-blocking threshold is determined.

[0089] The different dirty-blocking thresholds correspond to different attenuation ratios, and the controller of the air conditioner stores a plurality of dirty-blocking threshold ranges and the attenuation ratios corresponding to each dirty-blocking threshold range, that is, the attenuation ratio corresponding to the threshold can be determined by setting the dirty-blocking range in which the dirty-blocking threshold is located.

[0090] S412, the dirty-blocking refrigerating / cooling capacity is determined according to the standard refrigerating / cooling capacity of the air conditioner and the attenuation ratio.

[0091] The attenuation ratio is b, the standard refrigerating / cooling capacity is Q 标准 , and the dirty-blocking refrigerating / cooling capacity Q 脏堵 = Q 标准 *b.

[0092] In some embodiments, S200, the theoretical temperature-reaching time of the air conditioner for adjusting the first indoor temperature to the first set temperature is determined, including:

[0093] S210, the theoretical temperature-reaching time is determined according to the standard refrigerating / cooling capacity of the air conditioner.

[0094] When the air conditioner is in the heating mode, the standard cooling capacity is determined; when the air conditioner is in the cooling mode, the standard refrigerating capacity is determined.

[0095] The standard refrigerating / cooling capacity is actually the rated refrigerating / cooling capacity when the filter screen is not dirty-blocked; after the standard refrigerating / cooling capacity is determined, the theoretical temperature-reaching time can be determined according to the standard refrigerating / cooling capacity, the temperature change, and the indoor volume.

[0096] In some embodiments, S210, determining the theoretical temperature reaching time according to the standard refrigerating capacity / standard heating capacity of the air conditioner, comprising:

[0097] S211, determining the first temperature difference according to the first indoor temperature and the first set temperature.

[0098] Wherein, the first indoor temperature is T 室1 , the first set temperature is T 设1 , the first temperature difference is ΔT1, ΔT1=|T 室1 -T 设1 |.

[0099] Determining the theoretical temperature reaching time according to the first temperature difference, the indoor volume and the standard refrigerating capacity / standard heating capacity.

[0100] Wherein, the first temperature difference is ΔT1, the indoor volume is V, the standard refrigerating capacity / standard heating capacity is Q 标准 , the theoretical temperature reaching time is t 理论 , Wherein a is a constant term, generally a takes the value of 0.86.

[0101] Wherein, a is generally the ratio of the rated refrigerating capacity / rated heating capacity converted to the effective refrigerating capacity / heating capacity.

[0102] In some embodiments, the present application also provides a filter screen dirty block monitoring device 10, comprising an acquisition module 100, a judgment module 200 and a calculation module 300. The acquisition module 100 is used for acquiring the first indoor temperature, and acquiring the actual temperature reaching time of the air conditioner adjusting the first indoor temperature to the first set temperature after the air conditioner starts. The judgment module 200 is used for determining that the filter screen is dirty and blocked after determining that the actual temperature reaching time is greater than the theoretical temperature reaching time. The calculation module 300 is used for determining the theoretical temperature reaching time of the air conditioner adjusting the first indoor temperature to the first set temperature.
