[0021] Figure 1 The embodiments of the present application provide a schematic flowchart of an air conditioner plasma high-efficiency sterilization method.

[0022] Figure 2 The control process schematic diagram of the air conditioner plasma high-efficiency sterilization method provided by the embodiment of the present application is shown. DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings.

[0024] In the embodiment of the present application, the air conditioner is installed with a plasma generator for releasing positive and negative ions to achieve the sterilization effect. The higher the content of positive and negative ions, the better the sterilization effect.

[0025] In view of the purpose of improving the sterilization effect of the air conditioner, the embodiment of the present application designs a function of selecting whether to start the auxiliary chamber to supplement the content of positive and negative ions according to different air speeds of the air conditioner, so that the air conditioner is always in a state of high content of positive and negative ions, and has a good sterilization effect.

[0026] The indoor unit of the air conditioner is installed with a plasma generator in the air duct for releasing positive and negative ions for sterilization. Meanwhile, an auxiliary chamber is arranged in the indoor unit, and the auxiliary chamber is provided with a fan and a humidifier. Optionally, the auxiliary chamber is communicated with the air duct and arranged upstream of the plasma generator. The air blown by the fan and the moisture increased by the humidifier also pass through the plasma generator.

[0027] When the content of positive and negative ions in the air duct is low, the auxiliary chamber is started to supplement the content of positive and negative ions. The fan and the humidifier are arranged in the auxiliary chamber for controlling the state of air. Exemplarily, the fan and the humidifier are arranged in two gears I and II respectively, corresponding to different air speeds and moisture increase speeds.

[0028] The air speed and humidity will affect the content of positive and negative ions. With the increase of the air speed, the migration of positive and negative ions is accelerated, so that the content of positive and negative ions in the place with high air speed is increased. In a high-humidity environment, more moisture will be ionized as a carrier to generate more positive and negative ions, so the greater the humidity, the more the content of positive and negative ions.

[0029] Figure 1 The schematic flowchart of the air conditioner plasma high-efficiency sterilization method in the embodiment of the present application is shown. The method is applied to the above-mentioned air conditioner and includes the following steps.

[0030] S102, acquiring the current air gear of the indoor unit, and determining the air speed according to the current air gear.

[0031] The current air gear of the indoor unit can be acquired after the air conditioner is started. Based on the known relationship between the air gear and the air speed, the actual air speed corresponding to the current air gear can be determined.

[0032] S104, calculate the content of positive and negative ions in the air duct according to the wind speed.

[0033] In this embodiment, the content of positive and negative ions in the air duct is determined indirectly based on the wind speed. In the case of normal operation of the plasma generator, the greater the wind speed in the air duct, the faster the migration of positive and negative ions, and the higher the content of positive and negative ions in the air duct. By pre-collecting data of multiple wind speeds and corresponding contents of positive and negative ions, which are in a proportional relationship, the relationship between the two is obtained.

[0034] For example, the relationship between the wind speed and the content of positive and negative ions corresponding to the plasma generator is as follows: y = Ax + B, where y is the content of positive and negative ions, x is the wind speed, and A and B are coefficients. Then, according to the relationship between the wind speed and the content of positive and negative ions, the content of positive and negative ions corresponding to the wind speed can be calculated. In this embodiment, the relationship between the wind speed and the content of positive and negative ions can be determined in advance, so that the content of positive and negative ions is calculated based on the current wind speed. This method does not require detection hardware such as an ion concentration sensor, and can accurately determine the content of positive and negative ions at low cost.

[0035] S106, control the fan and the humidifier to operate at different gears according to the content of positive and negative ions.

[0036] In this embodiment, since the content of positive and negative ions is affected by the wind speed of the indoor unit, the auxiliary room needs to assist in the auxiliary promotion of the content of positive and negative ions to different degrees. The content of positive and negative ions can be determined in multiple ranges, and the fan and the humidifier of the auxiliary room use different gears when the content of positive and negative ions falls within different ranges.

[0037] Optionally, if the content of positive and negative ions is within a first range, the fan and / or the humidifier are controlled to operate at a first gear; if the content of positive and negative ions is within a second range, the fan and / or the humidifier are controlled to operate at a second gear.

[0038] Wherein, the lower limit of the first range is greater than the upper limit of the second range, the wind speed of the fan operating at the first gear is less than the wind speed operating at the second gear, and the humidifier operating at the first gear increases the humidity less than the humidifier operating at the second gear.

[0039] In the case of low content of positive and negative ions (corresponding to low wind speed of the indoor unit), the fan outputs a larger wind speed and the humidifier increases the humidity more, thereby greatly accelerating the migration of positive and negative ions, generating more positive and negative ions, and increasing the content of positive and negative ions in the air duct. In the case of high content of positive and negative ions (still lower than the target value of the content of positive and negative ions, corresponding to a higher wind speed of the indoor unit than the foregoing case), the fan outputs a smaller wind speed and the humidifier increases the humidity less, thereby less accelerating the migration of positive and negative ions, generating more positive and negative ions, and increasing the content of positive and negative ions in the air duct.

[0040] Once the positive and negative ion concentrations reach the target values, turn off the fan and humidifier.

[0041] Specifically, multiple ranges of positive and negative ion concentrations are defined, and the current positive and negative ion concentration falls within that range based on the following method, which also controls the operation of the fan and humidifier:

[0042] 1. If the positive and negative ion content y satisfies C≤y<D, then start the fan at speed II and the humidifier at speed II to replenish the positive and negative ion content in the air conditioning duct;

[0043] 2. If the positive and negative ion content y satisfies D≤y<E, then start the fan at speed I and the humidifier at speed II to replenish the positive and negative ion content in the air conditioning duct;

[0044] 3. If the positive and negative ion content y satisfies E≤y<F, then start the fan at speed II and the humidifier at speed I to replenish the positive and negative ion content in the air conditioning duct;

[0045] 4. If the positive and negative ion content y satisfies F≤y<G, then start the fan at speed I and the humidifier at speed I to replenish the positive and negative ion content in the air conditioning duct;

[0046] 5. If the positive and negative ion content y satisfies G≤y, then turn off the fan and humidifier.

[0047] In this embodiment, the fan speed at setting I is lower than that at setting II, and the humidity increase from setting I to setting II is less than the humidity increase from setting II. When the concentration of positive and negative ions is very low, both the fan and humidifier operate at their maximum speed to quickly increase the concentration. When the concentration is slightly low, either the fan or the humidifier is controlled to operate at a lower speed. In this embodiment, the humidifier operating at a high speed and the fan operating at a low speed corresponds to a lower concentration of positive and negative ions; the humidifier operating at a low speed and the fan operating at a high speed corresponds to a slightly higher concentration of positive and negative ions; both the humidifier and the fan operating at low speeds correspond to a higher concentration of positive and negative ions; and operation stops when the concentration of positive and negative ions reaches the target value.

[0048] For example, C takes the value 0, and D takes the value 500,000 / cm. 3 E is taken as 1 million / cm 3 F takes the value of 1.5 million units / cm³ 3 G is taken as 2 million units / cm 3 .

[0049] The air conditioner plasma efficient sterilization method provided by the embodiment of the application can calculate the positive and negative ion content in the air duct based on the air speed corresponding to the air damper of the air conditioner, and then determine whether to start the function of supplementing the positive and negative ion content in the auxiliary chamber according to the positive and negative ion content. Specifically, the fan and the humidifier can be controlled to use different gears according to the size of the positive and negative ion content, so as to accurately control the positive and negative ion content, keep the air conditioner in the optimal state of the positive and negative ion content, and have good sterilization effect.

[0055] S24, according to the different positive and negative ion content, the fan and the humidifier in the auxiliary chamber are started in different gears.

[0056] When the positive and negative ion content y meets 0≤y<50, the auxiliary chamber starts the fan gear II and the humidifier gear II to supplement the positive and negative ion content in the air duct of the air conditioner;

[0057] When the positive and negative ion content y meets 50≤y<100, the auxiliary chamber starts the fan gear I and the humidifier gear II to supplement the positive and negative ion content in the air duct of the air conditioner;

[0058] When the positive and negative ion content y meets 100≤y<150, the auxiliary chamber starts the fan gear II and the humidifier gear I to supplement the positive and negative ion content in the air duct of the air conditioner;

[0059] When the positive and negative ion content y meets 150≤y<200, the auxiliary chamber starts the fan gear I and the humidifier gear I to supplement the positive and negative ion content in the air duct of the air conditioner;

[0060] When the positive and negative ion content y meets 200≤y, the auxiliary chamber fan and the humidifier are closed.

[0061] Wherein, the fan speed of the fan gear II is greater than that of the fan gear I, and the humidifier gear II increases humidity faster than the humidifier gear I.
