Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method, storage medium, controller, and air conditioner for an air conditioner. Background Technology

[0002] As people's demands for quality of life increase, negative ion generators have gradually entered people's lives, and their use as air purification devices in air conditioners is becoming increasingly common. Negative ion generators mainly utilize high-voltage corona discharge to increase the negative ion content in the air, thereby improving air quality. The negative ion emission rate of a negative ion generator is positively correlated with the power of the high-voltage power supply; that is, the higher the power of the high-voltage power supply, the stronger the ionization ability of the negative ion emission end.

[0003] To increase the emission speed of negative ions in negative ion generators, related technologies employ methods such as increasing the power of the high-voltage power supply. However, when the power of the high-voltage power supply is high, a strong corona discharge phenomenon can easily occur between the negative ion emitting end and the negative ion guiding end, potentially producing unpleasant odors or noises. Furthermore, simply increasing the power of the high-voltage power supply does not change the overall power output, meaning the negative ion generator can only produce a constant number of negative ions when turned on, resulting in a relatively limited operating mode. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one object of this invention is to provide a control method, storage medium, controller, and air conditioner for an air conditioner, which adjusts the rate at which a negative ion generating module produces negative ions based on the concentration of negative ions in the air, thereby more effectively improving air quality.

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The control method, storage medium, controller, and air conditioner of the present invention are described below with reference to the accompanying drawings.

[0030] Figure 1 This is a flowchart of an air conditioner control method according to an embodiment of the present invention. Figure 1 As shown, the method includes:

[0031] S11, when the negative ion generating module has been running for a cumulative first preset time, the concentration of negative ions in the air is compared with the first preset concentration.

[0032] In this embodiment, during the process of generating negative ions through ionization, the negative ion generating module also produces active groups, high-energy electrons, and ultraviolet light. The active groups readily oxidize the proteins and nucleic acids on bacteria and viruses, causing them to decay; the high-energy electrons and negative ions have a breakdown etching effect, destroying the particles of bacteria and viruses; and ultraviolet light itself has a bactericidal function. Therefore, the operation of the negative ion generating module can improve air quality.

[0033] As one implementation method, the negative ion generating module can be controlled to operate simultaneously with the air conditioner being turned on, and its operating power can be a fixed preset power. The operation of the negative ion generating module purifies the air in the air duct, thereby improving the air quality of the environment where the air conditioner is located.

[0034] As another implementation method, the negative ion generating module can be controlled to operate simultaneously with the air conditioner's fresh air function, and its operating power can be a fixed preset power. The operation of the negative ion generating module purifies the introduced fresh air, thereby improving the air quality of the environment where the air conditioner is located.

[0035] To ensure the air quality improvement effect, after the negative ion generating module has been running for a first preset time, i.e., the air purification process has been completed for a first preset time, the concentration of negative ions in the air can be compared with the first preset concentration to determine the current air quality.

[0036] The first preset duration can be a fixed value, such as 20 minutes or 30 minutes; the first preset duration can also be a variable value, such as a user-defined input, or determined according to the area of ​​the space where the air conditioner is located. The larger the area, the longer the first preset duration. The area can be estimated based on the image of the space where the air conditioner is located captured by the camera on the air conditioner, or it can be a user-defined input.

[0037] Optionally, the negative ion concentration can be obtained by detecting air quality. For example, a correspondence between air quality and negative ion concentration can be established in advance, and the corresponding negative ion concentration can be obtained by looking up the correspondence when the air quality is obtained; the negative ion concentration can also be obtained directly by detection. Air quality and negative ion concentration can be detected by a detection device on the indoor unit of the air conditioner, or they can be obtained by communicating with specific detection equipment in the space where the air conditioner is located.

[0038] S12, if the negative ion concentration is less than or equal to the first preset concentration, then increase the operating power of the negative ion generating module to the first power.

[0039] The first preset concentration can be set as needed. For example, users with high requirements for air quality can set a relatively large first preset concentration.

[0040] S13, if the negative ion concentration is greater than the first preset concentration, the negative ion generating module is controlled to maintain the current operating state.

[0041] Specifically, if the negative ion concentration is less than or equal to the first preset concentration, it indicates that the negative ion concentration is not too high, and the effect on air purification is limited. In this case, the operating power of the negative ion generating module can be increased to the first power to accelerate the generation rate of negative ions. The first power can be the product of the aforementioned preset power and a coefficient P, where P is a constant greater than 1. If the negative ion concentration is greater than the first preset concentration, it indicates that the negative ion concentration is acceptable, and the effect on air purification meets the requirements. In this case, it is only necessary to maintain the operating power of the negative ion generating module at the first power to accelerate the generation rate of negative ions.

[0042] Therefore, this method can increase the speed at which the negative ion generating module generates negative ions by controlling the operating power of the negative ion generating module when the concentration of negative ions in the air is low, thereby rapidly increasing the concentration of negative ions in the air and improving air quality.

[0043] In some embodiments, such as Figure 2 As shown, the control method for an air conditioner may include:

[0044] S21, when the air conditioner turns on the fresh air function, the concentration of negative ions in the air is compared with the second preset concentration, wherein the second preset concentration is less than the first preset concentration.

[0045] S22, if the negative ion concentration is less than the second preset concentration, control the negative ion generating module to operate at the preset power.

[0046] Specifically, when an air conditioner activates its fresh air function, it largely indicates poor indoor air quality, necessitating the introduction of fresh air. To avoid unnecessary power consumption, the concentration of negative ions in the air around the air conditioner can be compared to a lower preset concentration. If the negative ion concentration is lower than the preset concentration, it indicates poor air quality in the space. In this case, the negative ion generator can be controlled to operate at a preset power to purify the introduced fresh air, thereby accelerating the improvement of air quality in the space around the air conditioner.

[0047] In some embodiments, the air conditioner also includes a humidification module, such as Figure 3 As shown, the method also includes:

[0048] S31, after the negative ion generating module runs at the first power for a second preset time, calculate the difference between the negative ion concentration in the air and the first preset concentration.

[0049] S32, compare the difference with the first difference threshold.

[0050] S33, if the difference is less than the first difference threshold, then control the humidification module and the negative ion generation module according to the difference and the fresh air humidity.

[0051] Here, "fresh air humidity" refers to the humidity of the fresh air introduced after the fresh air function is turned on. Of course, steps S31-S33 can also be implemented without turning on the fresh air function; in this case, simply replace "fresh air humidity" with the humidity of the space where the air conditioner is located. Optionally, a humidity sensor can be installed at the air duct inlet to detect humidity.

[0052] Specifically, if the difference between the negative ion concentration and the first preset concentration is less than the first difference threshold after the negative ion generating module operates at the first power for a second preset time, it indicates that the air purification still does not meet the requirements. At this time, the humidification module and the negative ion generating module can be controlled according to the difference and the fresh air humidity, so as to further increase the number and / or speed of negative ion generation by humidifying while generating negative ions, thereby more effectively improving air quality.

[0053] In some embodiments, such as Figure 4 As shown, in step S33, the humidification module and the negative ion generating module are controlled based on the difference and the humidity of the fresh air, including:

[0054] S41, compare the difference with the second difference threshold and the third difference threshold respectively, and compare the fresh air humidity with the first humidity threshold, wherein the third difference threshold is less than the second difference threshold, and the second difference threshold is less than the first difference threshold.

[0055] S42, if the difference is less than the third difference threshold and the fresh air humidity is less than the first humidity threshold, then adjust the operating power of the negative ion generating module to the second power and control the humidification module to operate at the first humidification amount, wherein the second power is P*Q1 times the preset power and Q1 is a constant greater than 1.

[0056] S43, if the difference is greater than or equal to the third difference threshold and less than the second difference threshold, and the fresh air humidity is less than the first humidity threshold, then adjust the operating power of the negative ion generating module to the third power, and control the humidification module to operate at the second humidification amount, wherein the third power is P*Q2 times the preset power, Q2 is a constant greater than 1, and Q2 is less than Q1, and the second humidification amount is less than the first humidification amount.

[0057] S44. If the difference is greater than or equal to the second difference threshold, or if the fresh air humidity is greater than or equal to the first humidity threshold, then adjust the operating power of the negative ion generating module to the fourth power, where the fourth power is P*Q3 times the preset power, Q3 is a constant greater than 1, and Q3 is less than Q2.

[0058] Among them, the aforementioned difference thresholds and humidification amounts can be calibrated as needed.

[0059] Specifically, if the difference between the concentration of negative ions in the air and the first preset concentration is less than a first difference threshold, it indicates that more negative ions need to be generated more quickly. In this case, the difference and humidity can be further compared, and the negative ion generating module and humidification module can be controlled according to different difference and humidity ranges. Specifically, three difference ranges and two humidity ranges can be defined. When the humidity is within a smaller range, the smaller the difference, the higher the operating power of the adjusted negative ion generating module. Furthermore, when the difference is within the two smaller difference ranges, humidification is also performed to increase the generation rate of negative ions. The smallest difference range corresponds to a higher humidification amount and a faster negative ion generation rate. When the humidity is within a larger range, only the operating power of the negative ion generating module is adjusted. Therefore, by adaptively adjusting the generation rate of negative ions based on negative ion concentration and humidity, both air purification and energy consumption can be balanced.

[0060] In some embodiments, the control method of the air conditioner may include: after the negative ion generating module operates at a second power, a third power, or a fourth power for a third preset time, returning to the step of calculating the difference between the concentration of negative ions in the air and a first preset concentration.

[0061] Therefore, through cyclical detection and control throughout the entire control process, air purification can be adaptively carried out according to real-time environmental parameters, thereby improving air quality.

[0062] In some embodiments, such as Figure 5 As shown, the negative ion generating module includes a discharge needle 1 and an electrode plate 2, and the humidification module includes a water tank 3 and an electromagnetic heating assembly. The electromagnetic heating assembly includes a high-frequency coil 4 and a magnetic conductor 5. The water tank 3 has a hollow cavity 31 and a water-filling cavity 32. An airflow path is formed through the hollow cavity 31. The discharge needle 1 is located in the airflow path, and the electrode plate 2 is located in the airflow path and closely attached to the water-filling cavity 32. The electrode plate 2 is electrically connected to the discharge needle 1. The electromagnetic heating assembly is used to heat the water in the water tank 3 to achieve humidification. The high-frequency coil 4 is located around the periphery of the water tank 3, such as when the high-frequency coil 4 is wound around the outside of the water-filling cavity 32. The magnetic conductor 5 is located inside the high-frequency coil 4. During electromagnetic heating, the water in the water tank 3 is released as steam from the outlet 33.

[0063] Among them, the magnetic conductor 5 can be a high-permeability tube, an electromagnetic induction rod, or an electromagnetic induction tube.

[0064] Specifically, power supply components can be respectively set for electrode plate 2 and high-frequency coil 4, so as to adjust the humidification capacity and the operating power of the negative ion generating module by controlling the power supply information of electrode plate 2 and high-frequency coil 4 through the power supply components. By placing electrode plate 2 and discharge needle 1 in the hollow cavity 31, the occurrence of odors or abnormal noises when the negative ion generating module generates negative ions can be reduced or avoided, and the size of the negative ion generating module can be guaranteed. At the same time, by "integrating" the negative ion generating module and the humidification module, the design of the air conditioner can be simplified, and the amount of negative ions generated can be guaranteed.

[0065] In summary, the control method of the air conditioner in this embodiment of the invention can adjust the generation rate of negative ions as needed; by placing the negative ion generating module in a hollow cavity surrounded by a water-filled cavity, the occurrence of odors or abnormal noises when generating negative ions can be reduced or avoided, and the size of the negative ion generating module can be guaranteed; humidification is achieved by electromagnetically heating the water in the water tank, which facilitates the design of the air conditioner and also ensures the amount of negative ions generated.
