The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

Please refer to FIG. 1 , the air conditioner according to the embodiment of the present invention includes a heat exchanger and an ion wind generator. The control method of the air conditioner includes the following steps:

S10: judging whether the temperature of the heat exchanger is less than or equal to the first threshold when the air conditioner is working in cooling mode;

S50: Control the ion wind generator to increase the second voltage increase when the ion wind generator has not reached the maximum gear, and the second voltage increase is smaller than the first voltage increase.

Referring to FIG. 2 , an air conditioner 100 according to an embodiment of the present invention includes a heat exchanger 10 , an ion wind generator 20 , a memory and a processor. The memory stores at least one program, and the processor is used to execute the at least one program. As an example, the air conditioner control method according to the embodiment of the present invention can be implemented by the air conditioner 100 according to the embodiment of the present invention, and can be applied to the air conditioner 100 .

Wherein, steps S10 to S50 of the method for controlling an air conditioner according to the embodiment of the present invention may be implemented by a processor. That is to say, the processor is used to execute the program to realize whether the temperature of the heat exchanger 10 is less than or equal to the first threshold when the air conditioner 100 is working in the cooling mode, and enters the anti-freezing sub-mode when the temperature is greater than or equal to the first threshold , judging whether the ion wind generator 20 is working at the maximum gear in the anti-freezing sub-mode, controlling the ion wind generator 20 to increase the first voltage increase when the ion wind generator 20 is working at the maximum gear, and in the ion wind generator 20 When the maximum gear is not reached, the ion wind generator 20 is controlled to increase the second voltage increase, and the second voltage increase is smaller than the first voltage increase.

Wherein, the storage may be an independent storage or a dedicated or dynamically allocated part of the storage of the air conditioner. The processor can be an independent processor or a dedicated or dynamically allocated part of the processor of the air conditioner.

When the air conditioner 100 is working in the cooling mode, the temperature of the heat exchanger 10 of the indoor unit is low, and the water vapor on the surface of the heat exchanger 10 will condense and cause frost and ice on the surface of the heat exchanger 10, affecting the performance of the air conditioner 100. normal operation.

In the control method of the embodiment of the present invention, the air conditioner 100 includes an ion wind generator 20, and the air is blown through the ion generator 20 during operation. The temperature of the heat exchanger 10 is the temperature of the refrigerant pipe of the heat exchanger, which can usually be detected by a temperature sensor. The first threshold can be set at the factory and stored in the memory, read and compared with the measured temperature of the heat exchanger 10 when the air conditioner 100 is working in cooling mode. Of course, the first threshold can also be set according to user requirements, and no limitation is set here. It can be considered that when the temperature of the heat exchanger 10 is greater than the first threshold, the state of the air conditioner 100 is normal. And when it is lower than the first threshold, there may be a hidden danger of freezing, and the anti-freezing sub-mode will be entered. It should be noted that the antifreeze sub-mode is a sub-mode of the cooling mode, rather than other modes for exiting the cooling mode.

When the temperature of the heat exchanger 10 is less than or equal to the first threshold, it can be considered that it is necessary to increase the air output at this time, so as to increase the temperature of the heat exchanger 10 to prevent freezing. The air output of the ion wind generator 20 increases with the increase of its operating voltage, therefore, in order to increase the air output, the voltage will be increased.

Specifically, before the increase, judge its current working gear, if it is already working at the maximum gear, then control the ion wind generator 20 to increase the first voltage increase, and when the maximum gear is not reached, then control the ion wind generator 20 Increase the second voltage boost. Among them, the working gear is set before leaving the factory, and each working gear corresponds to a working voltage. The higher the working voltage, the higher the gear, and the greater the air volume. The working gear of the ion wind generator 20 can be determined manually by the user, and of course the working gear can also be determined automatically according to environmental parameters, such as the temperature difference between the ambient temperature and the set temperature. It should be noted that the maximum gear is not the limit voltage of the ion wind generator 20. When it works at the maximum gear, the temperature of the heat exchanger 10 is still lower than the first threshold. It can be considered that the current working environment is relatively harsh , it is necessary to continue to increase the operating voltage, that is, to increase the first voltage increase, and the increase range is larger, or greater than the second voltage increase. In order to make the working voltage higher than the working voltage of the maximum gear, thereby increasing the air volume. And when the ion wind generator 20 is not working at the maximum gear, the working voltage can be increased appropriately, that is, the second voltage increase rate can be increased. The second voltage increase is smaller than the second voltage increase, the air volume is appropriately increased, the noise increases less, the user comfort is better, and at the same time, the heat exchanger 10 can be effectively prevented from freezing.

In summary, the air conditioner control method and the air conditioner 100 in the embodiment of the present invention, when the air conditioner 100 is working in cooling mode and the temperature of the heat exchanger 10 is lower than a predetermined threshold, the work of the ion wind generator 20 is increased. Voltage to increase the air volume, because in the cooling mode, the temperature of the ion wind generator 20 air outlet is higher than the temperature of the heat exchanger 10, which can effectively increase the surface temperature of the heat exchanger 10, thereby effectively preventing the heat exchanger 10 from freezing.

Please refer to Fig. 2 again, in some implementations, the air conditioner 100 is formed with an air duct, and the air duct is formed with an air inlet and an air outlet, and the ion wind generator 20 and the heat exchanger 10 are arranged in sequence from the air inlet to the air outlet. In the air duct.

Specifically, when the air conditioner 100 is working, air enters from the air inlet. The ion wind generator 20 specifically includes a high voltage collector and a high voltage generator. When the ion wind generator 20 is working, the air passes through the high-voltage generator of the ion generator 20 after primary filtration, and is ionized into positive ions and electrons after high-voltage discharge. Moving towards the high-voltage collector, after absorbing the electrons of the high-voltage collector, the reassembled air molecules have greater kinetic energy due to the avalanche effect, and can still obtain airflow with a certain speed, thereby generating ion wind. Further, the ionized wind is blown out from the air outlet through the heat exchanger 10 to complete the air supply. During the cooling process, the temperature of the ionized wind blown out by the ionized wind generator 20 is higher than the temperature of the surface of the heat exchanger 10 .

In addition, the ionic wind generator 20 can effectively kill harmful germs in the air through the ionization and discharge process in the process of generating the ionic wind, and at the same time generate negative oxygen ions to make the indoor environment more comfortable and refreshing.

Referring to Fig. 3, in some embodiments, the control method also includes the following steps:

S52: Determine whether the voltage of the ion wind generator after increasing the first voltage increase or increasing the second voltage increase is greater than or equal to the voltage threshold;

S54: When the voltage after the ion wind generator increases the first voltage increase or the second voltage increase is lower than the voltage threshold, control the ion wind generator to increase the predetermined voltage increase every predetermined time until the increase value reaches the first voltage increase or the second voltage increase. voltage increase;

S56: When the voltage of the ion wind generator after increasing the first voltage increase or increasing the second voltage increase is greater than or equal to the voltage threshold, control the ion wind generator to increase the predetermined voltage increase every predetermined time until the increased voltage reaches the voltage threshold.

In some embodiments, the processor is used to execute at least one program to realize judging whether the voltage of the ion wind generator 20 after increasing the first voltage increase or increasing the second voltage increase is greater than or equal to the voltage threshold. 20. When the voltage after increasing the first voltage increase or increasing the second voltage increase is lower than the voltage threshold, control the ion wind generator 20 to increase the predetermined voltage increase every predetermined time until the increase value reaches the first voltage increase or the second voltage increase, and When the ion wind generator 20 increases the voltage after the first voltage increase or the second voltage increase is greater than or equal to the voltage threshold, the ion wind generator 20 is controlled to increase the predetermined voltage increase every predetermined time until the increased voltage reaches the voltage threshold.

When increasing the voltage, in order to make the process smoother and the user experience better, increase the predetermined voltage every predetermined time, for example, the first voltage increase is 10kv, the predetermined time is 2s, and the predetermined voltage increase is 0.5kv, that is to say, every 2s Add 0.5kv, if the voltage threshold is not exceeded after adding 10kv, then add 10kv in total and take 40s in total. If the voltage threshold is exceeded after adding 10kv, then increase 0.5kv every 2s until the voltage threshold is reached. The second voltage boosting process is similar to the first voltage boosting process, and will not be repeated here.

Specifically, the ionizer 20 has a voltage threshold that it can reach, that is to say, the ionizer 20 can only work within the range of the voltage threshold, therefore, after entering the anti-heat wind sub-mode, it is judged whether the voltage exceeds the voltage after increasing the voltage. If the threshold is not exceeded, it will run at the increased actual voltage, if it exceeds the voltage threshold, it will run at the voltage threshold, so that the air output reaches the maximum value within the allowable voltage range.

In certain embodiments, the first threshold is less than or equal to 5 degrees Celsius.

It can be understood that when the temperature of the heat exchanger 10 is less than or equal to the first threshold, it can be considered that it is necessary to increase the air output to increase the temperature of the heat exchanger 10 . The first threshold can be set before leaving the factory or can be set according to the user's usage during use. The setting of the first threshold can ensure the safe and effective operation of the heat exchanger 10 and the air conditioner 100 .

Referring to Fig. 4, in some embodiments, the control method also includes the following steps:

S60: judging whether the air conditioner exits the cooling mode or whether the temperature of the heat exchanger is greater than or equal to the second threshold; and

S62: The air conditioner exits the cooling mode or exits the anti-freezing sub-mode when the temperature of the heat exchanger is greater than or equal to the second threshold.

In some embodiments, the processor is used to execute at least one program to realize judging whether the air conditioner 100 exits the cooling mode or whether the temperature of the heat exchanger 10 is less than or equal to the second threshold value and the air conditioner 100 exits the cooling mode or the heat exchanger When the temperature of 10 is greater than or equal to the second threshold, the antifreeze sub-mode is exited.

Specifically, when the air conditioner 100 exits the cooling mode, such as switching to a heating mode or other non-cooling mode, the temperature of the heat exchanger 10 will also be greater than the first threshold. Or when the temperature of the heat exchanger rises to be greater than or equal to the second threshold when the air is blown after being pressurized by the ion wind generator 20 , it can be considered that the working state of the heat exchanger 10 is relatively safe and stable.

In such embodiments, the second threshold is greater than the first threshold. In this way, it can be judged that the temperature rise of the heat exchanger 10 is effected by the ion wind generator 20 .

In such embodiments, the second threshold is greater than or equal to 7 degrees Celsius.

As mentioned above, when the temperature of the heat exchanger 10 rises from below the first threshold to the second threshold, it can be considered that the temperature increase of the heat exchanger 10 is effective. The second threshold is greater than or equal to 7 degrees Celsius, which can ensure the stable operation of the heat exchanger 10. At the same time, the difference between the second threshold and the first threshold is small to ensure the safe operation of the heat exchanger 10, that is, exit the anti-freezing sub-mode. It can be understood that when the ion wind generator 20 works in the anti-freezing sub-mode, the working voltage is relatively high, and the power consumption is relatively large, and the power consumption can be reduced by exiting the anti-freezing sub-mode in time.

In some embodiments, the control method also includes the steps of:

After exiting the antifreeze sub-mode, control the ion wind generator to work at the gear before the increase.

In some embodiments, the processor is used to execute at least one program to control the ion wind generator 20 to work at the gear before the increase after exiting the anti-freeze sub-mode.

After exiting the anti-freezing sub-mode, return to the original working gear, continue to work with the working gear originally set by the user or re-determine the working gear according to the environmental parameters for air supply. In this way, after exiting the anti-freezing sub-mode, working in the original working gear can reduce power consumption and at the same time meet the demand for air supply.
