Based on the hardware architecture, the embodiment of the self-cleaning control method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a diagram of an embodiment of a self-cleaning control method of an air conditioner according to the present invention, the self-cleaning control method of the air conditioner includes the following steps:
step S10, after entering the self-cleaning refrigeration stage of the air conditioner, acquiring the indoor environment temperature in the space acted by the air conditioner;
in the invention, the air conditioner can enter self-cleaning according to a fixed key on a remote controller, and can also be determined according to the cleaning degree of a heat exchanger in the air conditioner or the total running time of the air conditioner, and the air conditioner automatically enters self-cleaning when the concentration of dirt on the air conditioner is detected to be high or the total running time is more than 1000 hours or 800 hours. The air conditioner self-cleaning device comprises a refrigeration condensate water generation stage, a refrigeration frosting stage, a heating defrosting stage and a heating drying stage, wherein the refrigeration condensate water generation stage operates at the highest frequency or when the compressor is controlled to start to enter refrigeration operation, the operation frequency of the compressor of the air conditioner is increased so as to improve the capacity of the air conditioner for generating condensate water, and condensate water is generated quickly and greatly so as to meet the requirement of the air conditioner self-cleaning.
The method is used for controlling the refrigeration stage, and after the air conditioner enters the self-cleaning refrigeration stage, the indoor environment temperature in the space acted by the air conditioner is obtained. The indoor environment temperature is obtained through a temperature sensor arranged in the indoor environment, or is detected through wearable equipment worn by an indoor user, or is detected through a temperature sensor arranged on the air conditioner.
Step S20, when the indoor environment temperature is reduced to a first preset temperature, controlling the indoor fan of the air conditioner to reduce the wind speed to operate;
and step S30, after the frosting in the refrigeration stage is finished, controlling the compressor to enter heating and defrosting so as to clean the indoor heat exchanger of the air conditioner.
After the indoor ambient temperature is detected, the detected indoor ambient temperature is compared with a first preset temperature, which is a set temperature set by a user, that is, a temperature required by the user, for example, 24 degrees or 26 degrees, etc., and is set according to the user's requirement. Through the control of the air conditioner, the indoor environment temperature reaches the first preset temperature, and the indoor environment temperature meets the user requirements. When the air conditioner enters a self-cleaning refrigeration stage, in order to accelerate the speed of generating condensed water, the frequency of a compressor of the air conditioner is set to be the highest or the operating frequency higher than the temperature required by a user; the running frequency of the air conditioner entering self-cleaning is 10Hz-120Hz, or the frequency is more than 10Hz, the air conditioner runs at high frequency, the frequency of the air conditioner entering self-cleaning refrigeration can also be limited to be more than the preset frequency, the preset frequency is 10% or 60% of the highest frequency of the air conditioner, and the setting is carried out according to the requirement of generating condensed water by refrigeration; for example, the maximum compressor frequency is 130Hz, and the compressor frequency entering the self-cleaning refrigeration is higher than 13 Hz. Indoor ambient temperature reduces when first presetting the temperature, in order to guarantee that the air conditioner produces the demand of comdenstion water, do not reduce the compressor frequency, and control air conditioner indoor fan reduces the wind speed operation, reduce the air conditioner effect and to the influence of indoor space, and then when guaranteeing to produce the comdenstion water, reduce indoor fan wind speed, send into indoor environment with colder wind-force still less, can guarantee that the produced refrigerating capacity of compressor that hangs down produces still less influences indoor environment, the indoor environment in the effect space has been guaranteed, and the comfort level is improved. The control of the rotating speed of the indoor fan in the self-cleaning stage of the air conditioner is optionally applied to the situation that a user exists in an action space of the air conditioner, and before the air conditioner enters the self-cleaning stage, the user operates the air conditioner to use, the set temperature of the air conditioner is set or the air conditioner runs at the default temperature, and the set temperature or the default temperature is the first preset temperature. Of course, the above-mentioned control for reducing the wind speed of the indoor fan may also be applied to other scenarios, for example, a normal self-cleaning scenario of an air conditioner. After high-frequency refrigeration is carried out for a period of time, for example, 10 minutes or 8 minutes, the indoor heat exchanger of the air conditioner frosts, and a frosting stripping operation is carried out to strip the dirt on the indoor heat exchanger; after frosting for a period of time, for example, 2 minutes or 3 minutes, the compressor is stopped for 2s or 5s, and the compressor is started to heat; in the initial heating stage, the frost layer on the indoor heat exchanger is melted, the frost layer is changed into water in a heating mode, the indoor heat exchanger is cleaned, and then the indoor heat exchanger is dried in a heating mode, so that bacteria are prevented from being generated. In the heating and drying stage, if the outdoor environment temperature reaches a certain temperature, for example, 30 degrees or 35 degrees, the heating and drying stage is not required to be started, the three stages of refrigeration, frosting and heating and defrosting are directly adopted to complete the drying of the indoor heat exchanger, and the drying of the indoor heat exchanger can be completed in a natural air drying mode. The self-cleaning of the indoor heat exchanger of the air conditioner is completed by generating condensed water in refrigeration, frosting in refrigeration, defrosting in heating and drying in heating.
In the technical scheme that this embodiment provided, the air conditioner is at the refrigeration stage of automatically cleaning, at the quick refrigerated in-process of air conditioner, when indoor ambient temperature reduces to under the anticipated temperature of user, the control air conditioner reduces the wind speed operation of indoor fan, sends into less cold volume to indoor environment, and then when guaranteeing to produce the comdenstion water, controls indoor ambient temperature and satisfies the user's demand for air conditioner control is more reasonable, has increased the travelling comfort.
In an embodiment, referring to fig. 3, the controlling the indoor fan of the air conditioner to operate at a reduced wind speed when the indoor ambient temperature is reduced to the first preset temperature includes:
step S21, when the indoor environment temperature is reduced to a first preset temperature, the refrigeration state of the air conditioner is obtained;
and step S22, controlling the indoor fan of the air conditioner to reduce the wind speed to operate when the refrigeration state reaches the preset refrigeration state.
In this embodiment, when the air speed operation of the indoor fan of the air conditioner is reduced, the air speed operation needs to be adjusted according to the cooling state of the air conditioner, when the indoor environment temperature is reduced to a first preset temperature, that is, when the indoor environment temperature is reduced to a temperature below a temperature expected by a user, or when the indoor environment temperature is reduced to a temperature expected by a user, the cooling state of the air conditioner is obtained, the cooling state is the cooling capacity of the air conditioner, the stronger the cooling capacity is, the greater the effect on the temperature reduction of the indoor environment is, and when the cooling state of the air conditioner reaches the preset cooling state, the air speed operation of the indoor fan of the air conditioner is controlled to be reduced. For example, when the refrigeration capacity generated by the refrigeration state is higher than the refrigeration capacity required for maintaining the first preset temperature, it indicates that the preset state is satisfied, and when the refrigeration capacity required for maintaining the first preset temperature is lower than the first preset temperature, it is determined that the preset state is not satisfied, and when the preset state is not satisfied, it is not necessary to reduce the rotation speed of the indoor fan. The time for reducing the indoor fan of the air conditioner is more accurate through the judgment of the refrigeration state. When the preset refrigeration state is the preset frequency of the compressor, the preset frequency is 20Hz to 100Hz, or the preset frequency is greater than or equal to 20Hz, or may be defined as the preset frequency being 20% to 90% of the maximum operation frequency of the compressor of the air conditioner, for example, when the maximum operation frequency of the compressor is 130Hz, the preset frequency is greater than 26Hz and less than 117 Hz.
In an embodiment, referring to fig. 4, the step of controlling the indoor fan of the air conditioner to operate at a reduced wind speed when the cooling state reaches the preset cooling state includes:
step S211, determining a wind speed adjusting amplitude corresponding to the refrigeration state;
and S212, controlling the indoor fan of the air conditioner to reduce the wind speed to operate according to the wind speed adjusting amplitude.
The method comprises the steps that the reduction adjustment amplitude of an indoor fan is related to a refrigeration state, the higher the refrigeration capacity of the refrigeration effect is, the larger the adjustment amplitude of the fan is, the air speed adjustment amplitude is determined according to the refrigeration state, the air speed of the indoor fan of the air conditioner is controlled to be reduced to operate according to the air speed adjustment amplitude, a corresponding relation is established between the refrigeration state and the air speed adjustment amplitude, the air speed adjustment amplitude in the refrigeration state is determined according to the corresponding relation, and the refrigeration state can be judged by the coil temperature of an indoor heat exchanger or determined by the surface temperature of the indoor heat.
The air speed adjustment is related to the refrigeration state, and the adjustment amplitude is adjusted along with the difference of the refrigeration state, so that the air speed reduction control is more accurate, and the comfort level of the air conditioner is further improved.
In an embodiment, referring to fig. 5, after the step of controlling the indoor fan of the air conditioner to operate at a reduced wind speed when the indoor ambient temperature is reduced to the first preset temperature, the method further includes:
step S40, judging whether the condensed water generated in the refrigeration stage of the air conditioner meets the self-cleaning requirement of the air conditioner;
and step S50, when the self-cleaning requirement is not met, adjusting the wind speed of the indoor fan of the air conditioner according to the self-cleaning requirement of the air conditioner.
After reducing the wind speed of the indoor fan of the air conditioner, judging whether the condensate water generated in the refrigeration stage of the air conditioner meets the self-cleaning requirement of the air conditioner, if so, maintaining the current operation parameter operation of the air conditioner, if not, adjusting the wind speed of the indoor fan of the air conditioner according to the self-cleaning requirement of the air conditioner, namely, when the condensate water generating requirement is not met, adjusting the wind speed of the indoor fan again to meet the requirement of generating the condensate water, monitoring the generated condensate water and the indoor refrigeration to more accurately meet the self-cleaning requirement and the refrigeration requirement, improving the comfort level, and when the wind speed of the indoor fan of the refrigeration requirement and the self-cleaning requirement is switched, adopting a mode of setting time to switch between the wind speeds of the two requirements, for example, when the indoor refrigeration is about to be influenced, the wind speed is adjusted, and after the adjustment, the wind speed is adjusted back when the influence on the generated condensed water is about to be exerted.
In an embodiment, referring to fig. 6, when the self-cleaning requirement is not satisfied, the step of adjusting the wind speed of the indoor fan of the air conditioner according to the self-cleaning requirement of the air conditioner includes:
step S41, when the self-cleaning requirement is not satisfied, acquiring the difference between the condensed water generated in the refrigeration stage of the air conditioner and the condensed water required by the self-cleaning of the air conditioner;
and step S42, increasing the rotating speed of the fan according to the difference and the humidity of the indoor environment.
When the requirement for self-cleaning condensate water is not met, the difference value between the condensate water generated in the refrigeration stage of the air conditioner and the condensate water required by the self-cleaning of the air conditioner is obtained, the amount of the condensate water required to be generated is obtained, and then the rotating speed of a fan is increased or the humidity of the indoor environment is increased according to the amount and the humidity of the indoor environment. The difference value and the humidity of the indoor environment have a corresponding relation with the wind speed, and are obtained in advance, or the quantity of the generated condensed water and the humidity of the indoor environment have a corresponding relation with the wind speed. When the humidity is insufficient, the air can be humidified by an external device, such as a humidifier or the humidifying function of an air conditioner, so that the humidity requirement is met, and when the humidity is increased, more condensed water is generated.
Through the calculation of the difference value of the condensed water generated by refrigeration, the rotation speed of the indoor fan can be accurately obtained and adjusted, so that the adjustment of the indoor fan is more accurate.
In an embodiment of the present invention, after the difference is calculated, the humidity of the indoor environment is increased according to the difference, and the humidity is increased by humidifying the indoor environment, so that expected condensed water can be generated, and the difference of the condensed water generated by refrigeration and the humidity of the indoor environment have a corresponding relationship and are established in advance. Through humidification, can satisfy the demand that produces the comdenstion water of refrigeration when reducing the wind speed, and then satisfy the demand of automatically cleaning.
In an embodiment, referring to fig. 7, after the step of obtaining the indoor ambient temperature in the space served by the air conditioner after entering the cooling stage of the self-cleaning of the air conditioner, the method further includes:
and step S60, when the indoor environment temperature is reduced to a second preset temperature, controlling the compressor of the air conditioner to reduce the frequency operation, wherein the second preset temperature is less than the first preset temperature.
After the temperature of the indoor environment is obtained, when the temperature of the indoor environment is reduced to a second preset temperature, the second preset temperature is smaller than the first preset temperature, and the indoor environment temperature is far lower than the temperature expected by a user, so that the influence of refrigeration on the environment needs to be quickly reduced, and the compressor of the air conditioner is controlled to reduce the frequency operation. And the reduction of the frequency operation is related to the difference value between the second preset temperature and the first preset temperature, the amplitude of the frequency reduction is determined according to the temperature difference value, the larger the difference value is, the larger the reduction amplitude is, the smaller the difference value is, and the smaller the reduction frequency amplitude is.
