For example, when the determination condition is set as the second condition, if the humidity value is set by the user, the actual humidity value is set to the target humidity value by controlling only the opening of the solenoid valve 40, or by adjusting only the power of the electric heating element 3, or by controlling both the opening of the solenoid valve 40 and the power of the electric heating element 3, with the humidity value set by the user being the target humidity value (i.e., a preset value); if the user does not set the humidity value, the solenoid valve 40 is controlled to open and control the inflow rate to the default flow rate set by the air treatment device 100, and the power of the electric heating element 3 is adjusted to the default power set by the air treatment device 100.
The default flow rate and the default power can be specifically set according to practical application; the control of the inflow rate can be achieved by adjusting the opening of the solenoid valve 40.
The "whether the second condition is the preset value of the humidity set by the user" may be understood as whether the second condition is the preset value of the humidity set by the user when the user uses the device this time, or whether the second condition is the preset value of the humidity set by the user when the user uses the device last time.
For example, in the example of fig. 1, the air treatment device 100 includes an indoor unit 1, a steam delivery pipeline 2 and an electric heating element 3, the indoor unit 1 has an air outlet 11, the steam delivery pipeline 2 may be approximately in a zigzag arrangement, the first end 21 and the second end 22 are respectively two ends of the length of the steam delivery pipeline 2, the first end 21 is communicated with a water source, the second end 22 is arranged at the air outlet 11, the water storage section 23 is arranged between the first end 21 and the second end 22 and the water storage section 23 is vertically arranged, the electric heating element 3 is arranged at the water storage section 23 to heat water in the water storage section 23 so as to generate water vapor, the water vapor is driven to flow towards the second end 22 by using the pressure of the water vapor, and the water vapor is discharged into the room through the air outlet 11, so that the indoor humidification is realized, and the indoor comfort is improved.
According to the control method of the air treatment device 100 provided by the embodiment of the invention, indoor humidification can be realized, the air treatment device 100 can realize a self-cleaning function and an automatic water supplementing function, the intelligent degree is high, the air treatment device 100 is simple and convenient to use, meanwhile, the air treatment device 100 can meet different requirements of users on humidification amount, and the experience effect of the users is improved.
In some embodiments of the present invention, as shown in fig. 3, when the conditions are determined to be the first condition and the second condition, and when the user uses the air treatment device 100 for the first time and the user does not set the humidity value, the inflow rate is controlled to be a default flow rate, and the power of the electric heating element 3 is adjusted to be a default power. For example, when the determination conditions are set to the first condition and the second condition, if the user is the first use of the air treatment device 100 and the humidity value is not set when the user is using, the solenoid valve 40 is controlled to open and control the inflow water flow rate to the default flow rate set by the air treatment device 100, and the power of the electric heating element 3 is adjusted to the default power set by the air treatment device 100.
When the user uses the air treatment device 100 for the first time and the humidity value has been set, the humidity value is brought to a preset value by controlling at least one of the opening degree of the solenoid valve 40 and the power of the electric heater 3. For example, if the user uses the air treatment device 100 for the first time and the humidity value is set when the judgment conditions are set as the first condition and the second condition, the actual humidity value is set to the target humidity value (i.e., the preset value) by controlling only the opening of the solenoid valve 40, or by adjusting only the power of the electric heater 3, or by controlling both the opening of the solenoid valve 40 and the power of the electric heater 3.
When the user does not use the air treatment device 100 for the first time and the humidity value has been set, the humidity value is brought to a preset value by controlling at least one of the opening degree of the solenoid valve 40 and the power of the electric heating element 3. For example, if the user does not use the air treatment device 100 for the first time and the humidity value is set when the judgment conditions are set as the first condition and the second condition, the actual humidity value is set to the target humidity value (i.e., the preset value) by controlling only the opening of the solenoid valve 40, or adjusting only the power of the electric heater 3, or controlling both the opening of the solenoid valve 40 and the power of the electric heater 3.
When the user does not use the air treatment device 100 for the first time and the user does not set the humidity value, at least one of the opening degree of the solenoid valve 40 and the power of the electric heater 3 is controlled so that the humidity value reaches the previous humidity value. For example, when the determination conditions are set to the first condition and the second condition, if the user does not use the air treatment device 100 for the first time and the humidity value is not set when the user uses the air treatment device 100, the actual humidity value is set to the target humidity value by controlling only the opening of the solenoid valve 40, or by adjusting only the power of the electric heater 3, or by controlling both the opening of the solenoid valve 40 and the power of the electric heater 3, with the last humidity value of the air treatment device 100 being the target humidity value (i.e., a preset value).
Therefore, the control of the air treatment device 100 can be better matched with the requirements of users on humidity, so that the operation of the users is further simplified, and the convenience of the users is improved.
In some embodiments of the present invention, the priority of the humidity value set by the user at the time of use is higher than the priority of the humidity value set by the user at the time of last use, if the humidity value is set by the user at the time of use, whether the humidity value is set by the user at the time of last use or not is set by the user at the time of use, the humidity value set by the user at the time of use is taken as the target humidity value; in other words, when the second condition is whether the preset value of humidity is set when the user uses the device last time, the preset value of humidity needs to be combined to determine whether the user uses the device this time. Thereby, it is ensured that the control logic of the air treatment device 100 conforms to the operation habit of the user, so that the air treatment device 100 is convenient to use.
For example, if the humidity value is set when the user uses the preset value of the humidity, the humidity value set by the user is set as the target humidity value (i.e., the preset value) by controlling at least one of the opening of the electromagnetic valve 40 and the power of the electric heater 3 so that the humidity value reaches the preset value; if the user does not set the humidity value in the current use, controlling the water inflow speed to be a default speed, and adjusting the power of the electric heating element 3 to be a default power.
For another example, when the second condition is whether the preset humidity value is set when the user uses the second condition last time, if the user does not set the humidity value when using the second condition last time, the humidity value set last time by the user is taken as the target humidity value (i.e. the preset value), and at least one of the opening degree of the electromagnetic valve 40 and the power of the electric heating element 3 is controlled so that the humidity value reaches the preset value; if the humidity value is not set when the user uses the electric heating element and the humidity value is not set when the user uses the electric heating element, controlling the water inlet flow rate to be a default flow rate, and adjusting the power of the electric heating element 3 to be a default power; if the humidity value is set when the user uses this time, the humidity value set when the user uses this time is set as the target humidity value (i.e., the preset value) no matter whether the user sets the humidity value last time, and at least one of the opening of the electromagnetic valve 40 and the power of the electric heating element 3 is controlled to make the humidity value reach the preset value.
In some alternative embodiments of the present invention, the default flow rate of the solenoid valve 40 is 0.3kg/h to 0.8kg/h, and the default power of the electric heating element 3 is 300W to 500W, then the default flow rate may be selected within the range of 0.3kg/h to 0.8kg/h (inclusive), and the default power may be selected within the range of 300W to 500W (inclusive), so that the humidity value that the air treatment device 100 may default to achieve has a suitable range, and may be suitable for most users, and the applicability of the air treatment device 100 is ensured.
For example, the default flow rate controlled by the solenoid valve 40 may be 0.4kg/h and the default power of the electric heating element 3 400W, whereby the solenoid valve 40 and the electric heater 3 are mutually matched, so that the default humidity value of the air treatment apparatus 100 has good applicability. It will be appreciated that the default flow rate and default power may also be set to other values, and is not limited thereto.
In some embodiments of the present invention, as shown in fig. 4, the steam delivery pipeline 2 is provided with a water pressure measuring instrument 5 for detecting the water pressure of the water storage section 23, so that when the opening of the electromagnetic valve 40 needs to be adjusted to control the water inlet flow rate, the water pressure of the water storage section 23 can be combined for control, thereby facilitating the improvement of the accuracy of the water inlet flow rate control, avoiding the influence of the water pressure of the water storage section 23 on the accurate control of the water inlet flow rate, facilitating the realization of the accurate control of the humidification amount by the air treatment device 100, and improving the indoor adaptability.
It can be understood that the specific structure, principle and arrangement position of the water pressure measuring instrument 5 can be specifically set according to practical application, and only the water pressure measuring instrument 5 can be ensured to detect the water pressure of the water storage section 23.
In some embodiments of the present invention, the preset value includes a plurality of gears, where the plurality of gears respectively correspond to different humidity values or humidity ranges, so that when the preset value is set by a user, the preset value can be adjusted to a suitable gear according to the preset value, so as to better meet the differentiated requirements of the user, and improve the applicability and practicality of the air treatment device 100.
It can be appreciated that the user can adjust the gear of the air treatment device 100 just at the beginning of the use, and can also adjust the gear of the air treatment device 100 according to the requirement in the use process, so that the air treatment device 100 is more intelligent and has strong controllability. In this case, each time the user adjusts the air treatment device 100 to a certain gear, the air treatment device 100 adjusts the humidity value preset corresponding to the gear as the target humidity value, and at this time, at least one of the opening degree of the electromagnetic valve 40 and the power of the electric heater 3 can be controlled.
For example, the plurality of gears may be expressed by specific numerical values, the plurality of gears may be adjusted within a range of 45% -65% of the humidity preset value, four gears may be provided for each 5% of the gears, the four gears are respectively a first gear within a range of 45% -50% of the humidity preset value, a first gear within a range of 50% -55% of the humidity preset value, a first gear within a range of 55% -60% of the humidity preset value, and a first gear within a range of 60% -65% of the humidity preset value; the threshold value between two adjacent gears can be located at any one of the two adjacent gears. For another example, the plurality of gears may be expressed in text, and the plurality of gears may be a low gear, a standard gear, and a high gear, respectively, corresponding to different humidity values or humidity ranges, respectively.
It will be appreciated that the above gear settings are merely exemplary and are not a specific limitation of the invention; further, the adjustment of the shift position may be performed by the user himself or by the air treatment device 100 to the matching shift position according to the preset value of the user, but is not limited thereto.
Optionally, on each gear, the electric heating element 3 sets corresponding power, when the air processing device 100 is in a certain gear, the power of the electric heating element 3 is reasonable, so that energy saving and consumption reduction are further realized on the premise that the air processing device 100 can gradually adjust the humidity value to a preset value corresponding to the gear.
It will be appreciated that the power of the electric heating element 3 may be a certain value or a range in each gear; when the air treatment device 100 is operated in a certain gear, the electric heating element 3 may be kept operated with a certain power, or the power of the electric heating element 3 may be operated with a certain range of variation.
Optionally, in each gear, the electromagnetic valve 40 sets a corresponding inflow velocity, and when the air treatment device 100 is in a certain gear, the opening degree of the electromagnetic valve 40 is suitable, so as to ensure that the air treatment device 100 can gradually adjust the humidity value to a preset value corresponding to the gear.
It will be appreciated that in each gear, the inlet water flow rate corresponding to the solenoid valve 40 may be a certain value or a range; when the air treatment device 100 is operated in a certain gear, the solenoid valve 40 may be maintained at a certain opening degree, or the opening degree of the solenoid valve 40 may be adjusted within a certain range.

When the electromagnetic valve 40 is opened, the water pressure measuring instrument 5 operates to detect the water pressure of the water storage section 23 and feed back the detected water pressure value, and the air processing device 100 controls the opening of the electromagnetic valve 40 according to the detected water pressure value, so that accurate control of the water inlet speed is facilitated.
