The dehumidification mode actually operates a refrigeration cycle. Many users will turn on the dehumidification mode instead of the refrigeration mode when the indoor temperature is about 25°C. In order to maintain the indoor temperature at 25°C without cooling as much as possible, the air conditioner usually turns on the electric heater to perform heat compensation on the outlet air temperature during the dehumidification process.

[0041] Figure 1 is a schematic flowchart of a control method for dehumidifying an air conditioner 100 according to an embodiment of the present invention, and in combination with Figures 2 - 4 , the present invention provides a control method for dehumidifying an air conditioner 100.

[0042] As Figure 1 shown, the control method for dehumidifying the air conditioner 100 may include the following steps:

[0043] Step S100, obtaining the dehumidifying operation state of the air conditioner 100;

[0044] Step S200, judging whether the corresponding electric heating start condition is satisfied according to the dehumidifying operation state; if the corresponding electric heating start condition is satisfied, then execute step S300;

[0045] Step S300, controlling the electric heater 110 to start.

[0046] In this embodiment, the air conditioner 100 includes an electric heater 110, and the electric heater 110 is used to heat the air in the air outlet duct of the air conditioner 100 to increase the temperature of the air discharged from the air outlet of the air conditioner 100. This embodiment provides a perfect electric heating control logic.

[0047] Since in different dehumidifying operation states, the air conditioner 100 has different requirements for the starting time point of the electric heater 110. Therefore, in different dehumidifying operation states, this embodiment adopts different electric heating start conditions to be able to turn on the electric heater 110 in a timely and reasonable manner in different dehumidifying operation states, so as to achieve comfortable dehumidification in different dehumidifying operation states. This embodiment can avoid the situation of blowing hot air in summer or a large temperature drop but the electric heating not being turned on in time, improves the user's comfort, meets the use requirements of comfortable dehumidification, and achieves the purpose of improving the user experience.

[0048] In some alternative embodiments of the present invention, the dehumidifying operation state of the air conditioner 100 can be any one of a normal dehumidifying operation state, a state where dehumidification reaches the set temperature and the unit stops, and a state where it restarts after reaching the set temperature and stopping. This embodiment provides three dehumidifying operation states, and based on the above three dehumidifying operation states, it is convenient to set reasonable electric heating startup conditions.

[0049] In some alternative embodiments of the present invention, the air conditioner 100 includes a housing, a refrigerant circulation circuit, an indoor fan 140, an electric heater 110, etc. The refrigerant circulation circuit includes a compressor 130, an outdoor heat exchanger, a throttling device, and an indoor heat exchanger connected in sequence. A wind duct can be provided inside the housing, and an air return opening and an air outlet can be provided on the housing. The wind duct communicates the air return opening and the air outlet, and a part of the wind duct near the air outlet can be defined as an air outlet duct. The indoor heat exchanger, the indoor unit, and the electric heater 110 are all provided in the air outlet duct. Specifically, the electric heater 110 is located between the indoor heat exchanger and the air outlet. Under the action of the airflow disturbance of the indoor fan 140, the air in the indoor environment enters the wind duct from the air return opening, flows through the indoor heat exchanger for heat exchange (such as cooling and dehumidifying) after entering the air outlet duct, and when the electric heater 110 is turned on, the air that has undergone heat exchange through the indoor heat exchanger can be heated by the electric heater 110 and then sent into the indoor environment from the air outlet.

[0050] In some alternative embodiments of the present invention, as Figure 2 shown, after step S300, the dehumidifying control method of the air conditioner 100 may further include the following steps:

[0051] Step S400, judging whether the corresponding electric heating shutdown condition is satisfied according to the electric heating startup condition; if the corresponding electric heating shutdown condition is satisfied, then execute step S500;

[0052] Step S500, controlling the electric heater 110 to turn off.

[0053] In this embodiment, after the electric heater 110 is turned on, based on the electric heating startup condition, the corresponding electric heating shutdown condition is selected, so as to more reasonably control the start and stop of the electric heater 110, and further improve the user's comfort level, so as to further meet the use requirements of comfortable dehumidification, achieving the purpose of further improving the user experience.

[0054] In some alternative embodiments of the present invention, as Figure 3 shown, step S200 may include at least one of the following steps:

[0055] Step S201, when the air conditioner 100 is in a normal dehumidifying operation state, judging whether the electric heater 110 meets the first electric heating startup condition according to at least one of the indoor ambient temperature, the outdoor ambient temperature, the indoor fan state, the compressor startup time, and the set temperature;

[0056] Step S202, when the air conditioner 100 is in the state of dehumidifying and reaching the set temperature and stopping operation, determine whether the second electric heater starting condition is satisfied according to at least one of the indoor fan state, the time of reaching the set temperature and stopping operation, and the outdoor ambient temperature;

[0057] Step S203, when the air conditioner 100 is in the state of restarting after reaching the set temperature and stopping operation, determine whether the third electric heater starting condition is satisfied according to at least one of the indoor fan state, the compressor starting time, and the compressor frequency before reaching the set temperature and stopping operation.

[0058] In this embodiment, according to the characteristics of the normal dehumidifying operation state, the state of dehumidifying and reaching the set temperature and stopping operation, and the state of restarting after reaching the set temperature and stopping operation, the corresponding starting conditions of the electric heater 110 are set, so as to facilitate comfortable dehumidification in the above three dehumidifying operation states.

[0059] In some alternative embodiments of the present invention, step S200 may include: when the air conditioner 100 is in the normal dehumidifying operation state, obtain the current indoor ambient temperature, outdoor ambient temperature, indoor fan state, compressor starting time, and set temperature; according to the indoor ambient temperature, outdoor ambient temperature, indoor fan state, compressor starting time, and set temperature, determine whether the electric heater 110 satisfies the first electric heater starting condition. In this embodiment, through the above steps, it is more beneficial to reasonably turn on the electric heater 110.

[0060] In some alternative embodiments of the present invention, step S200 may include: when the air conditioner 100 is in the state of dehumidifying and reaching the set temperature and stopping operation, obtain the current indoor fan state, the time of reaching the set temperature and stopping operation, and the outdoor ambient temperature; according to the indoor fan state, the time of reaching the set temperature and stopping operation, and the outdoor ambient temperature, determine whether the second electric heater starting condition is satisfied.

[0061] In some alternative embodiments of the present invention, step S200 may include: when the air conditioner 100 is in the state of restarting after reaching the set temperature and stopping operation, obtain the current indoor fan state, the compressor starting time, and the compressor frequency before reaching the set temperature and stopping operation; according to the indoor fan state, the compressor starting time, and the compressor frequency before reaching the set temperature and stopping operation, determine whether the third electric heater starting condition is satisfied.

[0062] In some alternative embodiments of the present invention, the dehumidifying operation state of the air conditioner 100 is any one of the normal dehumidifying operation state, the state of dehumidifying and reaching the set temperature and stopping operation, and the state of restarting after reaching the set temperature and stopping operation.

[0063] When the air conditioner 100 is in the normal dehumidification operation state, the electric heating shutdown condition is the first electric heating startup condition, and the electric heating startup condition is the first electric heating shutdown condition; and / or, when the air conditioner 100 is in the dehumidification temperature-reached shutdown state, when the electric heating startup condition is the second electric heating startup condition, the electric heating shutdown condition is the second electric heating shutdown condition; and / or, when the air conditioner 100 is in the state of restarting after temperature-reached shutdown, when the electric heating startup condition is the third electric heating startup condition, the electric heating shutdown condition is the third electric heating shutdown condition.

[0064] This embodiment provides a more perfect electric heating control logic. In this embodiment, in any one of the normal dehumidification operation state, the dehumidification temperature-reached shutdown state, and the state of restarting after temperature-reached shutdown, the electric heating startup condition and the electric heating shutdown condition corresponding to this state are adopted, so that the start and stop of the electric heater 110 can be controlled more reasonably, and the user's comfort can be further improved, so as to further meet the use requirements of comfortable dehumidification, achieving the purpose of further improving the user experience.

[0065] In some alternative embodiments of the present invention, the first electric heating startup condition includes: the indoor ambient temperature is less than the first preset value, the first preset value is less than the set temperature; and, the indoor fan condition is on; and, the indoor ambient temperature is less than the first preset indoor temperature; and, the outdoor ambient temperature is less than or equal to the first preset outdoor temperature; and, the compressor startup time is greater than the first preset time.

[0066] Specifically, the first preset value can be set as needed. Preferably, the first preset value = set temperature - compensation value, and the compensation value can be set as needed. For example, the compensation value can be 0.5, and the first preset value = set temperature - 0.5. The indoor ambient temperature being less than the first preset value indicates that the indoor ambient temperature is in a supercooled state. Both the first preset indoor temperature and the first preset outdoor temperature can be set as needed. Preferably, the temperature values of the first preset indoor temperature and the first preset outdoor temperature are equal. For example, both the first preset indoor temperature and the first preset outdoor temperature are 22°C. The outdoor ambient temperature being less than or equal to the first preset outdoor temperature and the indoor ambient temperature being less than the first preset indoor temperature indicate that both the indoor ambient temperature and the outdoor ambient temperature are relatively low. The first preset time can be set as needed. For example, the first preset time can be 10S.

[0067] In this embodiment, when the air conditioner 100 is in the normal dehumidification operation state, the electric heater 110 is started only when both the indoor ambient temperature and the outdoor ambient temperature are relatively low and the indoor ambient temperature is in a supercooled state, so that the electric heater 110 can be turned on more reasonably to further improve the dehumidification comfort.

[0068] In some alternative embodiments of the present invention, the second electric heating startup condition includes: the indoor fan is in the on state; and, the temperature-reached shutdown time is greater than a preset shutdown time; and the outdoor ambient temperature is less than a second preset outdoor temperature, and the second preset outdoor temperature is less than a first preset outdoor temperature.

[0069] Specifically, the outdoor ambient temperature is less than the indoor ambient temperature. The preset shutdown time can be set as needed. For example, the preset shutdown time can be 10 min. The second preset outdoor temperature can be set as needed. For example, the second preset outdoor temperature is 20 °C. Since the temperature rises slowly after the compressor shuts down when the outdoor ambient temperature is less than the indoor ambient temperature, if the humidity in the room is relatively high, the relative humidity will rise, reducing the user's test experience. Therefore, when the air conditioner 100 is in the dehumidification temperature-reached shutdown state, when the outdoor ambient temperature is very low, the compressor shutdown time is long, and the indoor fan is on, the electric heater 110 is started, which can raise the room temperature, so that the compressor can be started earlier to dehumidify the indoor environment in a timely manner.

[0070] In some alternative embodiments of the present invention, the third electric heating startup condition includes: the indoor fan is in the on state; and, the compressor frequency before temperature-reached shutdown is less than a preset frequency; and, the compressor startup time after the compressor restarts is greater than a second preset time.

[0071] Specifically, the preset frequency can be set as needed, and the preset frequency is greater than or equal to the minimum dehumidification frequency. For example, the preset frequency = the minimum dehumidification frequency + 5. The second preset time can be set as needed. For example, the second preset time can be 10 S.

[0072] Before temperature-reached shutdown, the compressor operating frequency is less than the preset frequency. That is to say, before temperature-reached shutdown, the indoor environment temperature is maintained by controlling the compressor to operate at a low frequency to avoid excessive cooling of the indoor environment temperature, thereby reducing power consumption. Since before temperature-reached shutdown, the compressor has already adopted the low-frequency operation mode but still reaches the temperature-reached shutdown condition, therefore, after the compressor restarts and after the second preset time, the electric heater 110 is turned on to quickly raise the indoor environment temperature.

[0073] In some alternative embodiments of the present invention, when the air conditioner 100 is in the state of restarting after temperature-reached shutdown, the initial frequency executed by the compressor is the minimum dehumidification frequency. That is to say, when the compressor restarts, the minimum dehumidification frequency is used as the initial frequency, so that the air conditioner 100 can minimize the cooling capacity of the air conditioner 100 while dehumidifying, which is more conducive to improving the heating effect of the electric heater 110 to further improve the user's comfort level in the dehumidification mode.

[0074] In some alternative embodiments of the invention, when the electric heater 110 is started based on the first electric heating start condition, the electric heater 110 is turned off when the first electric heating off condition is satisfied. The first electric heating off condition includes any one or more of the following conditions: ① The indoor ambient temperature is greater than or equal to a second preset value and reaches a preset duration; ② The indoor fan is turned off; ③ The indoor ambient temperature is greater than or equal to a second preset indoor temperature; ④ The outdoor ambient temperature is greater than a third preset outdoor temperature; ⑤ The compressor is turned off.

[0075] Preferably, the first electric heating off condition includes: the indoor ambient temperature is greater than or equal to a second preset value, the second preset value is greater than the set temperature, and reaches a preset duration; or, the indoor fan is turned off; or, the indoor ambient temperature is greater than or equal to a second preset indoor temperature; or, the outdoor ambient temperature is greater than a third preset outdoor temperature; or, the compressor is turned off.

[0076] Specifically, the second preset value can be set as needed. For example, the second preset value = set temperature + 0.5. The second preset indoor temperature can be set as needed, and the second preset indoor temperature is greater than the first preset indoor temperature. For example, the second preset indoor temperature is 23°C. The third preset outdoor temperature can be set as needed, and the third preset outdoor temperature is greater than the first preset indoor temperature. For example, the third preset outdoor temperature is 23°C. The preset duration can be set as needed. For example, the preset duration is 2 min.

[0077] This embodiment provides a first electric heating off condition corresponding to the first electric heating start condition, avoiding too high indoor ambient temperature, so that the electric heating starter can be turned off more timely, thereby further improving the user experience.

[0078] In some alternative embodiments of the invention, both the second electric heating off condition and the third electric heating off condition include any one or more of the following conditions: the indoor ambient temperature is greater than or equal to the set temperature and reaches a preset duration, and at the same time the opening time of the electric heater 110 is greater than the shortest preset time; the user reduces the set temperature; the indoor fan is turned off; the compressor is turned off.

[0079] That is to say, when the electric heater 110 is started based on the second electric heating or third electric heating start condition, the electric heater 110 is turned off when any one or more of the following conditions are satisfied: ① The indoor ambient temperature is greater than or equal to the set temperature and reaches a preset duration, and at the same time the opening time of the electric heater 110 is greater than the shortest preset time; ② The user reduces the set temperature; ③ The indoor fan is turned off; ④ The compressor is turned off.

[0080] Preferably, both the second electric heating shutdown condition and the third electric heating shutdown condition include: the indoor ambient temperature is greater than or equal to the set temperature and reaches a preset duration, and at the same time, the startup time of the electric heater 110 is greater than the shortest preset time; or, the user reduces the set temperature; or, the indoor fan is turned off; or, the compressor is turned off.

[0081] Specifically, the preset duration can be set as needed. For example, the preset duration is 2 min. The shortest preset time can be set as needed. This embodiment provides an electric heating shutdown condition corresponding to the second electric heating startup condition and the third electric heating startup condition, so that the electric heating starter can be shut down more timely, avoiding the indoor ambient temperature from being too high, and further improving the user experience.
