It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

An air conditioning apparatus, a method of determining a water pollution state, and a storage medium according to some embodiments of the present application are described below with reference to fig. 1 to 5.

Embodiment one:

as shown in fig. 1, according to an embodiment of the present application, there is provided an air conditioning apparatus including: a water washing system 100 and a control device.

Specifically, the water washing system 100 includes: the housing 102 and the fan 104, the housing 102 comprises a liquid storage cavity 1020, and an air inlet 1022 and an air outlet 1024 which are communicated with the liquid storage cavity 1020; the fan 104 is communicated with the air inlet 1022, and the fan 104 supplies air to the liquid storage cavity 1020 through the air inlet 1022; the water washing system 100 is connected to a control device, which is used for determining the pollution state of the liquid in the liquid storage cavity 1020 according to the pollution reference parameter of the water washing system 100.

The invention provides an air conditioning device, which comprises a water washing system 100 and a control device, wherein the water washing system 100 comprises a shell 102 and a fan 104, the shell 102 is provided with a liquid storage cavity 1020, an air inlet 1022 and an air outlet 1024 which are communicated with the liquid storage cavity 1020, the fan 104 is communicated with the air inlet 1022 and is used for supplying air to the liquid storage cavity 1020 through the air inlet 1022, under the condition that the fan 104 is started, air enters the liquid storage cavity 1020 through the fan 104, impurities in the air are dissolved in the liquid after the air is fully contacted with the liquid in the liquid storage cavity 1020, and the purified air flows out from the air outlet 1024. The control device is connected with the water washing system 100, and is used for determining a pollution state of the liquid in the liquid storage cavity 1020 according to pollution reference parameters of the water washing system 100, so as to determine whether the liquid in the liquid storage cavity 1020 needs to be replaced or whether the liquid storage cavity 1020 needs to be cleaned, thereby not only ensuring the purification effect on air, but also avoiding the condition of low purification capability caused by various pollutants in the liquid after filtering the air.

It will be appreciated that a large amount of harmful substances (e.g., dust, particulates, bacteria, formaldehyde) in the air are soluble in water, so that the air is introduced into the liquid in the liquid storage chamber 1020 through the fan 104, so that a large amount of harmful substances are dissolved in water, and the effect of purifying the air is achieved. Specifically, the water washing system 100 further includes an air duct, an outlet of the air duct extends into the liquid storage cavity 1020 and is located below a liquid level of the liquid in the liquid storage cavity 1020, and the fan 104 supplies air into the liquid storage cavity 1020 through the air duct, so that the liquid discharged into the liquid storage cavity 1020 by the fan 104 can fully contact with the liquid, and the liquid flows out from the air outlet 1024 after filtering harmful substances through the liquid.

Further, the air conditioning apparatus further includes a decomposer capable of decomposing harmful substances dissolved in the liquid to avoid polluting water sources or air. Specifically, the decomposer comprises hydrogen peroxide and baking soda, and the hydrogen peroxide and the baking soda are dissolved in water, so that formaldehyde dissolved in water can be decomposed.

It will be appreciated that the contaminated condition includes at least two conditions, a condition requiring treatment and a condition not requiring treatment, i.e., requiring replacement of the liquid in the liquid storage chamber 1020 and/or cleaning of the liquid storage chamber 1020, i.e., the liquid in the liquid storage chamber 1020 is contaminated to a relatively high degree, and thus, no better purification of the air is achieved. The air can be continuously purified without treatment, i.e., without replacement of the liquid in the liquid storage chamber 1020 and/or cleaning of the liquid storage chamber 1020, i.e., with less contamination of the liquid in the liquid storage chamber 1020. Thus, by matching the control device with the water washing system 100, the relationship between the water changing times and the water quality cleaning can be balanced, so that the utilization rate of the liquid by the user is maximized, and the air purifying effect is best.

Further, the pollution reference parameter includes at least one of an on-time of the washing system 100, a water quality parameter, and an air outlet parameter of the air outlet 1024.

In this embodiment, the pollution reference parameter includes at least one of an opening duration of the water washing system 100, a water quality parameter and an air outlet parameter of the air outlet 1024, that is, the control device can determine a pollution state of the liquid in the liquid storage cavity 1020 according to the opening duration of the water washing system 100, for example, the longer the opening duration of the water washing system 100, the longer the duration of purifying the air, the more harmful substances are adsorbed, so that the liquid needs to be replaced after the opening duration reaches the duration threshold. The control device can also determine the pollution state according to the water quality parameter condition in the liquid storage cavity 1020 of the water washing system 100, namely, directly detect the liquid in the liquid storage cavity 1020, and determine the pollution state according to the detection result, namely, determine whether the liquid in the liquid storage cavity 1020 needs to be replaced or not. The control device can also determine the pollution state of the liquid in the liquid storage cavity 1020 according to the air outlet parameter of the air outlet 1024, namely, the air outlet parameter of the air outlet 1024 is detected, when the parameter of the fan 104 is unchanged, namely, the air inlet quantity is unchanged, the air outlet resistance is increased due to the increase of suspended matters or dust and other impurities in water, so that the current water quality state of the liquid in the liquid storage cavity 1020 can be reflected by detecting the air outlet parameter.

It can be understood that the opening time of the water washing system 100 is the cumulative opening time of the water washing system 100 from the last washing, for example, the opening time is recorded for each use of the water washing system 100 after cleaning, the cumulative opening time is obtained by adding the multiple opening time, and when the cumulative opening time reaches the time threshold, it is indicated that the water washing system 100 has been operated for a long time, so that it can be determined that the liquid in the liquid storage cavity 1020 needs to be replaced.

It will be appreciated that the liquid in the reservoir 1020 is directly detected, i.e. the concentration of a substance capable of reacting to the contamination level of the liquid, and that when the concentration of the contaminant reaches a certain threshold, it is determined that a liquid change is required.

It will be appreciated that under the condition that the operation parameters of the blower 104 are unchanged, the air supply amount in the liquid storage chamber 1020 is unchanged, if the liquid is clean enough, the air outlet amount is generally unchanged, if the concentration of the pollutants in the liquid is gradually increased, the adsorption of the pollutants in the air discharged into the liquid by the liquid is reduced, so that the air can flow to the air outlet 1024 with a large amount of impurities such as dust, and the air outlet amount is further affected, that is, the concentration of the pollutants in the liquid affects the air outlet amount, and therefore, the pollutant condition in the liquid can be determined according to the air outlet parameters.

Further, the reference parameters based on pollution include water quality parameters including: at least one of light transmittance, refractive index, reflectivity, transmission spectrum, absorption spectrum, and electrical conductivity of the liquid in the liquid reservoir 1020; the reference parameters based on pollution comprise air outlet parameters, wherein the air outlet parameters comprise: at least one of air outlet pressure of the air outlet 1024, air outlet temperature difference within a preset time, and air flow rate of the air outlet 1024.

In this embodiment, where the contamination reference parameter comprises a water quality parameter, the water quality parameter comprises at least one of light transmittance, refractive index, reflectance, transmission spectrum, absorption spectrum, conductivity of the liquid within the liquid reservoir 1020, i.e., by detecting at least one of light transmittance, refractive index, reflectance, transmission spectrum, absorption spectrum, conductivity of the liquid, the concentration of the contaminant within the liquid can be reflected, and thus the water quality change detected. When the pollution reference parameter includes an air-out parameter, the air-out parameter includes: at least one of air outlet pressure of the air outlet 1024, air outlet temperature difference within a preset time, and air flow rate of the air outlet 1024. That is, by detecting at least one of the air outlet pressure of the air outlet 1024, the air outlet temperature difference within a preset time, and the airflow velocity of the air outlet 1024, the pollutant concentration of the liquid can be reflected, and then the water quality change can be detected.

Specifically, a water quality sensor is placed in the liquid in the reservoir 1020 to measure the conductivity of the water. Because some suspended matters can be dissolved or collected in the water, the conductivity of the water can change with time, the water quality is detected by monitoring the conductivity change, and a user is reminded of changing water.

Specifically, a sensor for measuring the air volume is placed at the air outlet 1024, when the fan 104 is not changed, suspended matters or dust in water are increased, the resistance of the air outlet 1024 is increased, the current water pollution condition can be reflected by detecting the air volume, and the user is reminded of changing water.
