[0042] The embodiments of the present invention are described in detail below. Examples of the embodiments of the present invention are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0043] An embodiment of the present invention provides a method for controlling an air conditioner. Figure 1 FIG is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention. Figure 1 And refer to Figures 2 to 8An embodiment of the present invention provides a control method for an air conditioner. The air conditioner includes a water tank 10, a turbine 11 disposed within the water tank 10, a sterilization device 13 for sterilizing the water within the water tank 10, and a fan 20 for promoting airflow through the water tank. During operation, the fan 20 forces airflow through the upper portion of the water tank 10. The rotation of the turbine 11 drives the water within the water tank 10 to wash and purify the airflow.

[0044] To ensure airflow quality, the air conditioner control method includes: obtaining the rotational speed of the turbine 11 while the fan 20 and / or the turbine 11 are operating. The power of the sterilization device 13 is determined based on the rotational speed of the turbine 11, and the sterilization device 13 is operated at the determined power. This configuration effectively sterilizes the water and also provides a certain degree of sterilization of the airflow.

[0045] Specifically, the rotation of the turbine 11 can also break up the sediment of floating mold in the water, while the sterilization device 13 is also operating to kill the broken up floating mold, thereby improving sterilization efficiency and shortening the sterilization time. Moreover, since the sediment of floating mold is broken up, the sterilization device 13 does not need to use full power all the time. In other words, the sterilization device 13 operates at a power determined by the current rotational speed of the turbine, further saving energy and extending the service life of the sterilization device 13. The sterilization device 13 here can be an ultraviolet sterilizer or a flash sterilizer, etc.

[0046] In some embodiments of the present invention, Figure 2 As shown, determining the power of the sterilization device 13 based on the rotational speed of the turbine 11 includes: establishing a negative correlation model between the power of the sterilization device 13 and the rotational speed of the turbine 11. Based on the obtained rotational speed of the turbine 11, the corresponding current power of the sterilization device 13 is calculated according to the negative correlation model.

[0047] The negative correlation model between the rotation speed R of the turbine 11 and the power P of the sterilization device 13 can be: Here, the speed R of the turbine 11 ranges from 0 to K, and the power P of the sterilization device 13 ranges from 0 to T. That is, as the speed of the turbine 11 gradually decreases, the power of the sterilization device 13 gradually increases.

[0048] In some embodiments of the present invention, obtaining the rotational speed of the water turbine 11 includes obtaining the rotational speed of the fan 20, and determining the rotational speed of the water turbine 11 based on the rotational speed and / or air volume of the fan 20. After obtaining the rotational speed of the water turbine, the water turbine is rotated according to the rotational speed. To ensure the water-washing and purification effect of the airflow, the greater the rotational speed and / or air volume of the fan 20, the greater the rotational speed of the water turbine 11. The fan here can be a centrifugal fan or an axial flow fan.

[0049] In other embodiments of the present invention, obtaining the rotational speed of the water turbine is to detect the rotational speed of the fan using a detection device.

[0050] In some embodiments of the present invention, when the fan 20 and / or the turbine 11 are not operating, at least the sterilization device 13 is activated according to preset conditions. The preset conditions include, for example, the timing of activating the sterilization device 13. For example, the preset condition may be a preset period, i.e., the interval between repeated sterilizations. For another example, the preset period may be 7 to 9 hours, preferably 8 hours, meaning that the sterilization device 13 is activated every 8 hours. The interval between repeated sterilizations may be determined during air conditioner production or by the customer.

[0051] Furthermore, in some embodiments of the present invention, starting at least the sterilization device 13 according to a preset condition includes simultaneously starting the sterilization device 13 and the turbine 11 according to the preset condition.

[0052] In some embodiments of the present invention, Figure 3 As shown, after the sterilization device 13 and the water turbine 11 are turned on at the same time, the sterilization device 13 and the water turbine 11 are controlled to work according to the first preset program.

[0053] Furthermore, in some embodiments of the present invention, the first preset program is:

[0054] The sterilization device 13 and the turbine 11 are controlled to work for a preset sterilization time.

[0055] The preset sterilization time is divided into a plurality of consecutive preset time periods. During each preset time period, the turbine 11 operates at a preset speed, and the sterilization device 13 operates at a preset power. Furthermore, between two consecutive preset time periods, the preset speed of the turbine 11 corresponding to the first preset time period is greater than the preset speed of the turbine 11 corresponding to the second preset time period. A table can be used to determine the preset power of the sterilization device 13 and the preset speed of the turbine 11 corresponding to each preset time period.

[0056] In this embodiment, it can also be said that, Figure 5As shown, after the sterilization device 13 and the turbine 11 are simultaneously turned on, the sterilization device 13 and the turbine 11 operate according to the preset relationship between the sterilization device 13, the turbine 11, and the sterilization time. The sterilization time is divided into a plurality of consecutive preset time periods. The preset relationship between the sterilization device 13, the turbine 11, and the sterilization time includes a preset rotation speed of the turbine 11 and a preset power of the sterilization device 13 in each preset time period. In two adjacent preset time periods, the rotation speed of the turbine 11 corresponding to the first preset time period is greater than the rotation speed of the turbine 11 corresponding to the second preset time period, and the power of the sterilization device 13 corresponding to the first preset time period is less than the power of the sterilization device 13 corresponding to the second preset time period.

[0057] Furthermore, the multiple preset speeds of the turbine 11 corresponding to the multiple preset time periods are reduced according to the first preset rule; and the multiple preset powers of the sterilization device 13 corresponding to the multiple preset time periods are increased according to the second preset rule.

[0058] The first preset rule is that, between two adjacent preset time periods, the preset speed of the turbine corresponding to the first preset time period is greater than the preset speed of the turbine 11 corresponding to the second preset time period by one-fifth of the maximum speed. The second preset rule is that, between two adjacent preset time periods, the preset power of the sterilization device corresponding to the first preset time period is less than the preset power of the sterilization device corresponding to the second preset time period by one-fifth of the maximum power.

[0059] In some embodiments of the present invention, in the table, the preset speed of the turbine 11 corresponding to the first preset time period is K, and the preset power of the sterilization device 13 corresponding to it is 0. The preset speed of the turbine 11 corresponding to the second preset time period is four-fifths of K, and the preset power of the sterilization device 13 corresponding to it is one-fifth of T. The preset speed of the turbine 11 corresponding to the third preset time period is three-fifths of K, and the preset power of the sterilization device 13 corresponding to it is two-fifths of T. The preset speed of the turbine 11 corresponding to the fourth preset time period is two-fifths of K, and the preset power of the sterilization device 13 corresponding to it is three-fifths of T. The preset speed of the turbine 11 corresponding to the first preset time period is one-fifth of K, and the preset power of the sterilization device 13 corresponding to it is four-fifths of T.

[0060] In some embodiments of the present invention, Figure 4 As shown, after the sterilization device 13 and the turbine 11 are turned on at the same time, one of the sterilization device 13 and the turbine 11 is controlled to work according to a second preset program, and the other of the sterilization device 13 and the turbine 11 is controlled to work according to a preset relationship between the sterilization device 13 and the turbine 11.

[0061] Furthermore, in some embodiments of the present invention, the second preset program is:

[0062] The sterilization device 13 and the turbine 11 are controlled to work for a preset sterilization time.

[0063] The preset sterilization time is divided into multiple consecutive preset time periods.

[0064] During each preset time period, the turbine 11 is operated at a preset speed, and within two adjacent preset time periods, the preset speed of the turbine 11 corresponding to the first preset time period is greater than the preset speed of the turbine 11 corresponding to the second preset time period. The turbine's multiple preset speeds corresponding to multiple preset time periods are decreased according to a third preset rule. Alternatively, within each preset time period, the sterilization device 13 is operated at a preset power, and within two adjacent preset time periods, the preset power of the sterilization device 13 corresponding to the first preset time period is less than the preset power of the sterilization device 13 corresponding to the second preset time period. The sterilization device's multiple preset powers corresponding to multiple preset time periods are increased according to a fourth preset rule.

[0065] The third preset rule here can be a rule different from the first preset rule, or they can be the same. The fourth preset rule here can be a rule different from the second preset rule, or they can be the same.

[0066] In this embodiment, the preset speed of the water turbine 11 is gradually reduced from a high speed, and the power of the sterilization device 13 is controlled according to the preset relationship between the sterilization device 13 and the water turbine 11. Alternatively, the preset power of the sterilization device 13 is gradually increased from a low speed, and the speed of the water turbine 11 is controlled according to the preset relationship between the sterilization device 13 and the water turbine 11.

[0067] In some embodiments of the present invention, the preset relationship between the sterilization device 13 and the turbine 11 is a negative correlation. For example, the preset relationship between the sterilization device 13 and the turbine 11 conforms to the above-mentioned negative correlation model.

[0068] Specifically, the preset sterilization time is 10 minutes, and the sterilization time is evenly divided into 5 consecutive preset time periods. In the first preset time period, the speed of the turbine 11 group is K ，According to the above-mentioned negative correlation model, the power of the sterilization device 13 is zero. During the second preset time period, the rotation speed of the turbine group 11 is four-fifths of K. According to the above-mentioned negative correlation model, the power of the sterilization device 13 is one-fifth of T. During the third preset time period, the rotation speed of the turbine group 11 is three-fifths of K. According to the above-mentioned negative correlation model, the power of the sterilization device 13 is two-fifths of T. During the fourth preset time period, the rotation speed of the turbine group 11 is two-fifths of K. According to the above-mentioned negative correlation model, the power of the sterilization device 13 is three-fifths of T. During the fifth preset time period, the rotation speed of the turbine group 11 is one-fifth of K. According to the above-mentioned negative correlation model, the power of the sterilization device 13 is four-fifths of T.

[0069] In some embodiments of the present invention, during the first preset time period of the above-mentioned multiple consecutive preset time periods, the power of the sterilization device 13 is zero, and the water and the substances therein are moved by rapid stirring first, and then sterilization begins, thereby improving the sterilization efficiency.

[0070] In some embodiments of the present invention, the air conditioner control method further includes detecting and determining whether the water level in the water tank 10 is less than a preset level. If not, an alarm signal is issued, and the sterilization device 13 and the turbine 11 are shut down while the fan 20 is operating. When the fan 20 is about to start, the sterilization device 13 and the turbine 11 are prohibited from starting. Issuing an alarm signal prevents the airflow from being affected by insufficient water flow and prevents energy from being wasted by idling the sterilization device 13 and the turbine 11. In some embodiments, a liquid level gauge 12 is provided on the water tank to monitor the water level in the water tank 10.

[0071] In some embodiments of the present invention, Figure 8 As shown, the sterilizing device 13 is arranged on the bottom wall of the water storage tank 10, and a quartz glass 15 is arranged above the sterilizing device 13. The quartz glass 15 can prevent the sterilizing device 13 from irradiating and causing aging of the water storage tank components.

[0072] An embodiment of the present invention further provides another control method for an air conditioner, the control method comprising: when the fan 20 and / or the turbine 11 are not working, simultaneously starting the sterilization device 13 and the turbine 11 according to preset conditions.

[0073] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
