As shown in fig. 1, the indoor unit of the air conditioner includes a condensed water collecting device 10 and an oxygen generating device 20 disposed therein. Wherein, the condensed water collecting device 10 is arranged below the indoor heat exchanger and is used for collecting the condensed water generated by the indoor heat exchanger. One end of the oxygen generating device 20, namely a water inlet, is connected with a water outlet of the condensed water collecting device 10 through a pipeline; the other end of the oxygen-making device 20, namely the air outlet, is communicated with the air outlet of the indoor unit through a pipeline. The air outlet of the oxygen generator 20 is connected with two air outlet pipelines, one pipeline is communicated with the air outlet of the indoor unit, and oxygen generated by the oxygen generator 20 is sent into the indoor unit. The other pipe is communicated with the outside of the room, and the gas such as hydrogen generated by the oxygen generator 20 is discharged to the outside of the room. Here, the oxygen generation principle of the oxygen generator 20 is to electrolyze water into oxygen and hydrogen by electrolyzing condensed water.

Optionally, the indoor unit of the air conditioner further includes an oxygen humidifying device 40 connected to the oxygen pipe of the oxygen generating device 20. Here, in order to avoid direct discharge of dry oxygen into the indoor air, discomfort is caused to the user. The oxygen generated by the oxygen generator 20 is humidified before being discharged into the room. Thus, the comfort level of the air environment can be effectively improved. In addition, the temperature of the oxygen after humidification is prevented from being too low, and the fluctuation of the indoor temperature is avoided. The oxygen humidifying device 40 has a heating function, and changes the water temperature by adjusting the power. Meanwhile, the heating water can also increase the humidity inside the oxygen humidifying device 40 to help humidifying the oxygen.

Optionally, the indoor unit of the air conditioner further includes a water storage device 30. The water storage device 30 is communicated with the condensed water collecting device 10 through a pipeline and is used for replenishing water for the condensed water collecting device 10 or discharging condensed water in the condensed water collecting device 10 into the water storage device 30. Here, during the wet summer season, the indoor heat exchanger may generate a large amount of condensed water in the cooling mode of the air conditioner. When the amount of the water stored in the condensed water collecting device 10 reaches the upper limit value, the condensed water in the condensed water collecting device 10 may be drained to the water storage device 30. Meanwhile, in winter dry seasons, the air conditioner operates in a heating mode, and the indoor heat exchanger does not produce condensed water any more. In this case, the condensed water in the condensed water collecting device 10 is not enough to make the oxygen generator 20 generate enough oxygen, and the water storage device 30 is needed to supplement water for the condensed water collecting device 10.

Furthermore, the water storage device 30 can also be connected to the oxygen production device 20 through a pipeline, i.e. the water in the oxygen production device 20 can be directly supplied through the condensed water collection device 10 or the water storage device 30. In this way, when the amount of water in the condensate water collecting device 10 is insufficient, the water can be directly supplied from the water storage device 30.

As shown in fig. 2, an embodiment of the present disclosure provides a method for controlling air conditioning indoor air, including:

s101, acquiring the indoor current air quality by the processor under the condition of air conditioner operation.

S102, if the current air quality is lower than the preset quality, the detection element detects the condensed water amount of the condensed water collection device.

S103, controlling the oxygen generator to start and operate by the processor under the condition that the amount of the condensed water is larger than the first water amount threshold value.

In the embodiment of the disclosure, the indoor air quality can be acquired in real time or periodically during the operation process of the air conditioner. Specifically, the concentration of oxygen or carbon dioxide in the indoor air is detected by a sensor, and a corresponding threshold value is set. For determining the indoor air quality, for example, an oxygen threshold is set, and when the current oxygen concentration in the indoor air is lower than or equal to the oxygen threshold, poor indoor air quality is indicated. Or a carbon dioxide threshold value is set, and when the concentration of the carbon dioxide in the current air is higher than the carbon dioxide threshold value, the indoor air quality is poor. Here, the preset quality may be a carbon dioxide threshold value or an oxygen threshold value, or the like. Further, the detection period can be determined according to the running time of the air conditioner. Specifically, when the air conditioner operation time is less than or equal to the preset time, the detection period is a first time, and the first time may be 20 to 30 minutes. And when the running time of the air conditioner is longer than the preset time, detecting the indoor current air quality in real time or every second time, wherein the second time can be 5-10 minutes. Thus, the appropriate detection period can be set in combination with the operation time length of the air conditioner. The indoor air quality can be prevented from being repeatedly detected when the indoor air quality is better at the early stage of the operation of the air conditioner.

And when the current air quality indicates that the indoor air is poor, judging whether the amount of condensed water in the condensed water collecting device is sufficient or not. Here, a first water amount threshold is set for determining the amount of condensed water. If the amount of condensed water is greater than the first water amount threshold, it indicates that the amount of condensed water is sufficient. At the moment, the oxygen generation device can be controlled to start to operate so as to ionize the condensed water to generate oxygen and improve the indoor air quality.

By adopting the method for controlling the air conditioner to condition the indoor air, provided by the embodiment of the disclosure, the condensed water generated by the indoor heat exchanger during the air conditioner refrigeration operation can be recovered. And the oxygen generator is started under the condition that the indoor air quality is reduced and the amount of condensed water is sufficient due to the long-time operation of the air conditioner. The oxygen generator electrolyzes the condensed water to generate oxygen, so as to improve the quality of indoor air. Therefore, condensed water generated by the operation of the air conditioner can be fully utilized, and the indoor air quality can be improved.

Optionally, in step S101, the processor obtains indoor current air quality, including:

the detection element detects the oxygen concentration and the carbon dioxide concentration of the current air in the room.

The processor calculates a ratio of the oxygen concentration to the carbon dioxide concentration.

Here, in order to determine the indoor air quality more accurately, the air quality is reflected by the relative change of the gas. Specifically, the oxygen concentration and the carbon dioxide concentration of indoor air are detected; and calculating to obtain the ratio of the oxygen concentration to the carbon dioxide concentration. The current indoor air quality is represented by the ratio. The relative change can reflect the air quality more accurately than a single change in oxygen concentration or carbon dioxide concentration.

Referring to fig. 3, an embodiment of the present disclosure provides another method for controlling air-conditioning indoor air, including:

s201, the processor acquires the indoor current air quality under the condition of air conditioner operation.

S202, if the current air quality is lower than the preset quality, the detection element detects the condensed water amount of the condensed water collection device.

S203, controlling the oxygen generator to start and operate by the processor under the condition that the amount of the condensed water is larger than the first water amount threshold value.

S204, detecting the current humidity of the indoor environment by a detection element; and under the condition that the current humidity is less than or equal to the humidity threshold value, the processor controls the oxygen humidifying device to be started, and adjusts the operating parameters of the oxygen humidifying device according to the current humidity.

In the embodiment of the present disclosure, it is determined whether the oxygen humidification device needs to be turned on to humidify the generated oxygen according to the current humidity of the indoor environment. Here, the value of the humidity threshold may range from 50% to 60%. When the current humidity is below the humidity threshold, it indicates that the indoor ambient humidity is low. In this case, if oxygen is directly supplied into the room, dry oxygen is inhaled by the user, causing discomfort to the user. Therefore, the dry oxygen needs to be humidified and then discharged into the room. When the indoor environment humidity is high, the dry oxygen is humidified after being discharged into the room, and then is inhaled by the user. Furthermore, after the oxygen humidifying device is started, the operating parameters of the oxygen humidifying device are adjusted according to the current humidity. Here, the operation parameter may be a humidification power, or an opening degree of a corresponding valve, or the like. An adjusting valve can be arranged at the air inlet of the oxygen humidifying device, and the entering amount of oxygen can be adjusted. Specifically, the lower the current humidity is, the greater the operating power of the oxygen humidification device is, or the smaller the opening degree of the valve is. The valve opening of the air inlet is adjusted, so that the situation that the pressure of the oxygen humidifying device is overlarge due to excessive oxygen and part of oxygen is sent into a room without being humidified can be avoided. Adjust oxygen humidification device's operating power, can adjust the inside humidity of oxygen humidification device, power is big more, and the inside humidity of oxygen humidification device is high more for the oxygen that overflows from the aquatic can further be by the internal environment humidification, like this, when internal pressure is great, also can guarantee that oxygen is humidified.

Optionally, in step S204, the processor adjusts an operation parameter of the oxygen humidification device according to the current humidity, including:

the processor determines the humidification specific gravity of the oxygen according to the difference value between the current humidity and the humidity threshold value.

The processor adjusts the operation power of the oxygen humidifying device according to the corresponding relation between the humidifying specific gravity of the oxygen and the power of the oxygen humidifying device.

Generally, the greater the difference between the current humidity and the humidity threshold, the greater the humidification specific gravity of the oxygen. Here, the current humidity RH_{When in use}With humidity threshold RH_sThe relationship between the difference Δ RH of (d) and the humidification specific gravity P of oxygen can be determined by referring to table 1. Alternatively, the humidified specific gravity may be linearly related to the difference. Further, the operating power is determined by combining the corresponding relation between the humidification specific gravity and the power of the oxygen humidification device. For example, different humidification specific gravities correspond to the running power of different gears.

		RH₂＜ΔRH	P₃

Referring to fig. 4, an embodiment of the present disclosure provides another method for controlling air-conditioning indoor air, including:

s301, the processor acquires the indoor current air quality under the condition of air conditioner operation.

S302, if the current air quality is lower than the preset quality, the detection element detects the condensed water amount of the condensed water collection device.

And S303, controlling the oxygen generator to start and operate by the processor under the condition that the condensed water amount is greater than the first water amount threshold value.

S304, the processor controls the oxygen humidifying device to be started; and adjusting the operating parameters of the oxygen humidification device according to the current humidity.

In the embodiment of the disclosure, when the oxygen generation device is started, the oxygen humidification device is synchronously started. The air conditioner can operate in a cooling or heating mode to reduce the humidity of the indoor environment. Thus, oxygen is humidified while oxygen is being generated. And the operation parameters of the oxygen humidifying device are adjusted by combining the current humidity. Thereby realizing the humidity that improves oxygen, improving user's comfort level. For adjusting the operating parameters of the oxygen humidifier, reference is made to the above.

Referring to fig. 5, an embodiment of the present disclosure provides another method for controlling air-conditioning indoor air, including:

s401, the processor acquires the indoor current air quality under the condition of air conditioner operation.

S402, if the current air quality is lower than the preset quality, the processor acquires the running mode of the air conditioner; in the case of the air conditioner operating in the cooling mode, the detection element detects the amount of condensed water of the condensed water collection device.

And S403, controlling the oxygen generator to start and operate by the processor under the condition that the amount of the condensed water is greater than the first water amount threshold value.

In the embodiment of the disclosure, when the current air quality indicates that the indoor air is poor, the operation mode of the air conditioner is acquired. And under the condition that the air conditioner operates in a refrigeration mode, detecting the amount of condensed water of the condensed water collecting device. Here, since the condensed water is generated during air-conditioning cooling, the amount of water is detected during air-conditioning cooling. When the air conditioner heats, condensed water is basically not available, and the water quantity in the condensed water collecting device is inevitably insufficient. So that the step of detecting the amount of water can be omitted.

Optionally, in the case that the air conditioner operates in the heating mode, or in the case that the amount of the condensed water is less than or equal to the first water amount threshold, the processor controls the water storage device to replenish water to the condensed water collection device.

Here, in the case where the air conditioner operates in the cooling mode and the amount of the condensed water is insufficient, or the air conditioner operates in the heating mode, the water storage device is controlled to replenish water to the condensed water collection device. Specifically, a high water level detecting meter may be provided in the condensed water collecting device, and when the amount of water in the condensed water collecting device reaches a high water level, the water storage device is controlled to stop supplying water to the condensed water collecting device. And when the amount of the condensed water is larger than the first water amount threshold value, the oxygen generation device is controlled to start and operate. In addition, the water quantity of the condensed water collecting device is detected in real time in the operation process of the oxygen production device. And under the condition that the water amount is less than or equal to the first water amount threshold value, controlling the water storage device to replenish water for the condensed water collecting device. Therefore, in the oxygen generation process, the sufficiency of water and the non-intermittence of oxygen generation are ensured, and the efficiency of improving the indoor air quality is improved.

Optionally, the processor controls the water storage device to replenish water for the condensed water collecting device, including:

and under the condition that the water amount is greater than the first water amount threshold value, the processor adjusts the water replenishing rate of the condensed water collecting device according to the running power of the oxygen generating device.

In the embodiment of the disclosure, the water storage device is used for replenishing water for the condensed water collecting device. According to the foregoing, when the water amount of the condensed water collection device is greater than the first water amount threshold, the oxygen generation device is controlled to start operation. Meanwhile, the water storage device can continuously replenish water for the condensed water collecting device because the water amount in the condensed water collecting device does not reach a high water level. And further, adjusting the water replenishing rate according to the running power of the oxygen generating device. Here, the operating power of the oxygen plant determines the oxygen production; and the amount of water required is known from the oxygen production. Under the condition that the water outlet pipe diameter of the water storage device is known and the water outlet speed is known, the water outlet quantity in unit time can be calculated. In order to ensure the continuity of oxygen generation, the water yield of the water storage device is required to be greater than or equal to the water yield required by the oxygen generation device in unit time under the set operating power. Therefore, the minimum value of the water replenishing rate of the condensed water collecting device can be reversely deduced according to the operating power of the oxygen generating device. And adjusting the water replenishing rate of the condensed water collecting device to be more than or equal to the minimum value. Optionally, in the air-conditioning operation cooling mode, the water replenishing rate of the condensed water collecting device is adjusted to be equal to the minimum value. Here, condensed water is generated in the cooling mode, so the water replenishment rate may be slightly low.

Optionally, the processor controls the oxygen plant to shut down in the event the air quality is greater than or equal to a preset quality.

Here, when the indoor air quality is better, namely the indoor air quality meets the preset quality, the oxygen generation device can be controlled to be closed. Meanwhile, a water storage device and an oxygen humidifying device linked with the oxygen generating device are also correspondingly closed.

The embodiment of the disclosure provides a device for controlling an air conditioner to adjust indoor air, which comprises an acquisition module, a detection module and a control module. The acquisition module is configured to acquire the indoor current air quality under the condition that the air conditioner is operated; the detection module is configured to detect the amount of condensed water of the condensed water collection device if the current air quality is lower than a preset quality; the control module is configured to control the oxygen generation device to start operation when the amount of condensed water is larger than a first water amount threshold.

By adopting the device for controlling the air conditioner to adjust the indoor air, provided by the embodiment of the disclosure, the condensed water generated by the indoor heat exchanger during the refrigeration operation of the air conditioner can be recovered. And the oxygen generator is started under the condition that the indoor air quality is reduced and the amount of condensed water is sufficient after the air conditioner operates for a long time. The oxygen generator electrolyzes the condensed water to generate oxygen, so as to improve the quality of indoor air. Therefore, condensed water generated by the operation of the air conditioner can be fully utilized, and the indoor air quality can be improved.
