It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
With the improvement of the requirements of users on the quality of life, the air conditioner with the self-cleaning function is gradually replacing the traditional single heat pump unit and becomes a new favorite in the market. However, the current air conditioner with the self-cleaning function only performs the self-cleaning function but does not judge the performance effect.
The invention provides an air conditioner self-cleaning control scheme, which judges the self-cleaning effect after an air conditioner executes a self-cleaning command, so that a user can intuitively know the cleaning condition of a heat exchanger at the moment and provides a judgment basis for judging whether to carry out multiple self-cleaning.
Fig. 1 is a schematic method diagram of an embodiment of a self-cleaning control method for an air conditioner according to the present invention. The control method can be implemented in a main control module of the air conditioner.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner self-cleaning control method includes at least step S110, step S120 and step S130.
Step S110, before the air conditioner executes the self-cleaning function, acquiring a first operation parameter and a first indoor heat exchanger temperature of the air conditioner within a preset time before the air conditioner is shut down.
The first operating parameter includes, for example: the speed of the inner fan, the speed of the outer fan, the number of steps of the throttle valve, and/or the operating frequency of the compressor. Optionally, the first indoor heat exchanger temperature is an average value of indoor heat exchanger temperatures detected within a preset time period during which the operation parameters are stable before the air conditioner is shut down.
Specifically, the air conditioner main control module records the unit operation state and operation parameters in real time. When the air conditioner main control module receives a control instruction for executing the self-cleaning function, the air conditioner main control module autonomously selects a time period T1-T2 with stable operation parameters (the fluctuation range is smaller than a preset threshold value), the time period is delta T, the real-time temperature of the heat exchanger of the indoor unit is detected through a temperature sensor arranged on the heat exchanger of the indoor unit, the real-time temperature of the heat exchanger of the indoor unit of the air conditioner is automatically memorized, and the average temperature T1 of the real-time temperature is calculated.
And step S120, after the air conditioner executes the self-cleaning function, controlling the air conditioner to operate according to the first operation parameter, and recording the temperature of a second indoor heat exchanger of the air conditioner within a preset time length.
Optionally, the second indoor heat exchanger temperature is an average value of a plurality of indoor heat exchanger temperatures detected within a preset time after the air conditioner is controlled to operate stably according to the first operating parameter.
Specifically, the air conditioner is restarted after being stopped to execute one self-cleaning, the air conditioner is controlled to stably operate according to parameters (namely first operation parameters) in a time period from T1 to T2 before the self-cleaning, the real-time temperature of the heat exchanger of the indoor unit of the air conditioner within a preset time length delta T is memorized, and the average temperature T2 of the real-time temperature is calculated.
And step S130, determining the self-cleaning effect of the air conditioner according to the temperature of the first indoor heat exchanger and the temperature of the second indoor heat exchanger.
In one embodiment, whether the indoor heat exchanger surface satisfies the cleanliness condition is determined according to whether a temperature difference Δ T (T2-T1) between the second indoor heat exchanger temperature T2 and the first indoor heat exchanger temperature T1 reaches a preset temperature difference threshold X. If the temperature difference value delta T reaches the preset temperature difference threshold value X, determining that the surface of the indoor heat exchanger meets a clean condition; and if the temperature difference value delta T does not reach the preset temperature difference threshold value X, determining that the surface of the indoor heat exchanger does not meet the cleaning condition.
The preset temperature difference threshold value X is determined according to the attenuation degree of the heat exchange effect before and after the heat exchanger is dirty and blocked, and can be determined through multiple experimental verification, so that the situation that the self-cleaning effect is detected to be inconsistent with the actual effect due to unreasonable setting of the value is avoided, and therefore error information is output.
Because the operation parameters in the time period of participating in calculation and judgment before and after self-cleaning are consistent, the dust and dirt accumulated on the surface of the indoor heat exchanger can reduce the air volume participating in circulation, and the air volume participating in circulation after self-cleaning is executed can be increased; when the unit outputs a certain amount of cold, the temperature of the inner pipe can rise after self-cleaning; when the delta T is larger than or equal to X, the self-cleaning effect of the unit is ideal, and the surface of the heat exchanger is clean; when the delta T is less than X, the self-cleaning effect of the unit is not ideal, and the surface of the heat exchanger is still dirty, blocked and not clean enough.
Optionally, the method further comprises: and after the self-cleaning effect of the air conditioner is determined, controlling the air conditioner to continuously operate according to the current environmental parameters. In order to reduce the influence on the comfort of the air conditioner, the air conditioner exits the judgment logic of the self-cleaning effect, and automatically selects proper operation parameters to continue operation according to the current environment parameters (such as the indoor environment temperature and/or the outdoor environment temperature).
Optionally, the method further comprises: and if the surface of the indoor heat exchanger does not meet the cleaning condition, sending corresponding prompt information to determine whether to execute the self-cleaning function again. Specifically, if it is determined that the surface of the indoor heat exchanger is not clean and the self-cleaning effect of the unit is not ideal, corresponding prompt information is sent to prompt a user to automatically select whether to execute one self-cleaning again.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner self-cleaning control method provided by the present invention with a specific embodiment.
Fig. 2 is a schematic method diagram of an embodiment of a self-cleaning control method for an air conditioner according to the present invention. The air conditioner main control module records the operation state and the operation parameters of the unit in real time as shown in fig. 2. When the unit receives the instruction of executing the self-cleaning function, the air conditioner main control module autonomously selects a time period T1-T2 with stable operation parameters, automatically memorizes the real-time temperature of the heat exchanger of the air conditioner indoor unit and calculates the average temperature T1 through a temperature sensor arranged on the heat exchanger of the indoor unit, and restarts after one self-cleaning is executed. And after the operation is stable according to the parameters in the time period from T1 to T2 before self-cleaning, automatically memorizing the real-time temperature of the heat exchanger of the air conditioner indoor unit in the time period of delta T and calculating the average temperature T2 of the real-time temperature. And calculating the temperature difference delta T of the heat exchangers of the internal machine before and after self-cleaning as T2-T1. Judging whether the delta T meets the judgment condition, wherein if the delta T is larger than or equal to X, the self-cleaning effect of the unit is considered to be ideal, the surface of the heat exchanger is clean, and the self-cleaning effect judgment is quitted; if delta T is less than X, the self-cleaning effect of the unit is not ideal, and the surface of the heat exchanger is dirty, blocked and unclean.
