Based on the hardware architecture of the air conditioner, the embodiment of the humidification control method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a humidification control method of an air conditioner according to the present invention, including the steps of:
step S100, determining the humidification quantity to be output of the air conditioner;
in this embodiment, the air conditioner is provided with a humidifying water tank, the humidifying water tank is connected with a water pump, the rotating speed of the water pump is adjustable, and the air conditioner can inject humidifying water into the humidifying water tank through the water tank. And a heating electrode is arranged in the humidification water tank and is connected with a power supply circuit of the air conditioner, and the heating electrode comprises a cathode and an anode. When the power supply circuit can apply power supply voltage to the heating electrode and the heating electrode is in contact with the humidification water, ions exist in the humidification water, so that the anode, the cathode and the power supply circuit form a loop, the humidification water can be heated, the humidification water is heated, and the air conditioner operates in a humidification mode.
When the air conditioner runs in the humidifying mode, the heating electrode has a corresponding power supply voltage, and the power supply voltage is the current power supply voltage. When the air conditioner operates in the humidifying mode, the humidifying quantity is set, and can be the humidifying quantity output in unit time, namely the humidifying quantity to be output, the humidifying quantity to be output is theoretically equal to the steam quantity to be output of the humidifying water tank, actually, the steam quantity to be output is larger than the humidifying quantity to be output, the steam quantity to be output is multiplied by a coefficient to be the humidifying quantity to be output, and the coefficient is smaller than 1 and can be obtained through testing.
The output humidification quantity to be output represents the humidification capacity of the air conditioner in unit time, the air conditioner can be provided with a plurality of humidification gears, each humidification gear corresponds to different humidification capacities, and the output humidification quantity to be output can be determined according to the humidification gears. In addition, the air conditioner can also determine according to the humidity difference between the set humidity and the indoor humidity, and when the set humidity is greater than the indoor humidity, if the humidity difference is greater, the larger the humidification quantity to be output is. Of course, the humidification amount to be output may also be determined by the humidification instruction, for example, when the humidification instruction is a strong humidification instruction, the humidification amount to be output is the maximum humidification amount output by the air conditioner per unit time. It is understood that the amount of humidification to be output may be determined by a humidification level, a humidification instruction, or a difference between a set humidity and indoor humidity.
Step S200, determining a target operation parameter of a humidifying component according to the amount of humidification to be output, wherein the target operation parameter of the humidifying component comprises at least one of a target rotating speed of the water pump and a target power supply voltage of the heating electrode;
after determining the amount of humidification to be output, the air conditioner may determine a target operation parameter of the humidification part according to the amount of humidification to be output, the humidification part being at least one of the water pump and the heating electrode, that is, the target operation parameter of the humidification part includes at least one of a target rotation speed of the water pump and a target power supply voltage of the heating electrode.
The air conditioner stores a mapping relation table of the humidification amount to be output and the operation parameter of the humidifying component, and can determine the target operation parameter according to the mapping relation table, the humidification amount to be output and the humidifying component.
And step S300, controlling the humidifying component to operate according to the target operation parameters.
After the target operation parameters are determined, the air conditioner can control the humidifying component to operate according to the target operation parameters. It should be noted that the air conditioner may modulate the signal according to the target operation parameter, so as to input the signal to the power supply circuit, so that the humidification component operates according to the target operation parameter. Specifically, the operating parameters of the humidifying component and the power supply voltage of the humidifying component have a mapping relation, and the air conditioner determines the target power supply voltage of the humidifying component according to the mapping relation and the target operating parameters, namely determines the target power supply voltage of at least one of the water pump and the heating electrode; the air conditioner determines the duty ratio according to the maximum output voltage of the power supply circuit and the target power supply voltage, so that the signal corresponding to the humidifying component is modulated according to the duty ratio, and the modulation of the signal is modulated through the PWM module; after the signal is modulated, the signal is input to the power supply circuit, so that the power supply circuit provides the target power supply voltage to the humidifying component.
In the technical scheme provided by the embodiment, a humidifying water tank of an air conditioner is connected with a water pump, a heating electrode is arranged in the humidifying water tank, the air conditioner determines the amount of humidification to be output, so that the target operation parameters of a humidifying component of at least one of the water pump and the heating electrode are determined according to the amount of humidification to be output, and the humidifying component operates according to the determined target operation parameters; because the air conditioner heats the humidifying water through the heating electrode, the water vapor output by the air conditioner during humidification is clean water vapor, impurities in the humidifying water are prevented from entering a room, and clean humidification of the air conditioner is realized.
Referring to fig. 3, fig. 3 is a second embodiment of the humidification control method of the air conditioner according to the present invention, and based on the first embodiment, after step S200, the method further includes:
step S400, determining the current power supply voltage of the heating electrode;
step S500, determining a target water level of the humidification water tank according to the current power supply voltage and the humidification quantity to be output;
in this embodiment, the amount of humidification to be output is a constant amount in a period of time in which the humidification water tank needs to generate an amount of steam to be output equal to the amount of humidification to be output, that is, the amount of steam to be output is also constant in the period of time, and the humidification means includes a water pump, that is, the air conditioner adjusts only the rotation speed of the water pump. The current power supply voltage of the heating electrode is unchanged, so that the larger the current of the heating electrode is, the more the steam quantity generated by the humidifying water tank in unit time is, and the relationship between the current and the steam quantity generated by the humidifying water tank in unit time under different power supply voltages can be measured. Further, the magnitude of the current in the electrode is related to the surface area of the heating electrode immersed in the humidification water tank, the larger the surface junction of the heating electrode immersed in the humidification water is, the more ions in the humidification water in contact with the heating electrode are, and the larger the current of the heating electrode is, and based on the principle, the air conditioner can directly establish the mapping relation between the surface area of the heating electrode and the humidification quantity to be output under different power supply voltages.
Referring to fig. 4, step S500 includes:
step S510, determining a target surface area of the heating electrode immersed in humidification water according to the amount of humidification to be output and the current power supply voltage, the humidification water tank being provided with the humidification water;
step S520, determining the depth of the heating electrode immersed in the humidifying water tank according to the target surface area;
step S530, determining a target water level of the humidification water tank according to the depth.
After the current power supply voltage and the amount of humidification to be output are obtained, the air conditioner can determine the surface area of the heating electrode immersed in the humidification water according to the current power supply voltage, the amount of humidification to be output and the mapping relation, wherein the surface area is the target surface area. The heating electrode is perpendicular to the water surface in the humidification water tank, and therefore, the relationship between the surface area and the depth of the heating electrode immersed in the humidification water can be measured. The air conditioner can determine the depth of the heating electrode to be immersed into the humidifying water tank according to the target surface area.
The heating electrode is fixed in the humidifying water tank, namely the height of the heating electrode in the humidifying water tank is consistent, so that the air conditioner can determine the target water level according to the depth of the heating electrode immersed in the humidifying water tank. For example, the distance between the bottom of the heating electrode and the bottom of the humidification water tank is 20cm, and the depth of the heating electrode immersed in the humidification water tank is 4cm, then the target water level is 20cm +4cm or 24 cm.
And 600, after the rotating speed of the water pump is adjusted to enable the water level in the humidifying water tank to reach the target water level, the step of controlling the humidifying component to operate according to the target operation parameters is executed.
The air conditioner can determine the target rotating speed of the water pump according to the amount of humidification to be output, specifically, the rotating speed of the water pump represents the water inflow of the humidification water tank in unit time, the amount of humidification to be output represents the water outflow of the humidification water tank in unit time, and the water outflow needs to be equal to the water inflow. Therefore, a mapping relation between the amount of humidification to be output and the rotating speed of the water pump can be established, and the air conditioner can determine the target rotating speed of the water pump according to the mapping relation and the amount of humidification to be output. After the target rotating speed is determined, the water pump can be controlled to operate at a larger rotating speed firstly, so that the water level in the humidifying water tank reaches the target water tank, and then the water pump is controlled to operate at the target rotating speed, so that the water level in the humidifying water tank is maintained at the target water tank, namely, the current in the heating electrode is constant, and the air conditioner outputs constant humidification quantity in unit time.
In the technical scheme provided by the embodiment, the air conditioner determines the amount of humidification to be output of the air conditioner and the current power supply voltage of the heating electrode so as to determine the target water level of the humidification water tank, and then adjusts the rotating speed of the water pump according to the amount of humidification to be output so as to maintain the water in the humidification water tank at the target water level for constant humidification; because the air conditioner heats the humidifying water through the heating electrode, the water vapor output by the air conditioner during humidification is clean water vapor, impurities in the humidifying water are prevented from entering a room, and clean humidification of the air conditioner is realized.
Referring to fig. 5, fig. 5 is a schematic diagram of a detailed flow of step S510 in fig. 4, where step S510 includes:
step S511, determining the surface area of the heating electrode immersed in the humidification water according to the amount of humidification to be output and the current power supply voltage;
step S512, determining the conductivity of the humidification water;
step S513, correcting the surface area according to the conductivity of the humidification water to obtain a target surface area.
In this embodiment, the ion concentration in the humidification water is constant. However, in the humidification process of the air conditioner, pure water vapor is output from the humidification water tank, ions remain in the humidification water tank, and the concentration of the ions in the humidification water increases along with the increase of the humidification time of the air conditioner. The higher the ion concentration is, the higher the conductivity in the humidification water is, and the higher the conductivity is, the higher the current of the heating electrode is, so that the steam generated by heating the heating electrode is larger. Therefore, in determining the target surface area of the heating electrode, it is necessary to take into account the influence of the electric conductivity of the humidification water.
The air conditioner determines the surface area of the heating electrode immersed in the humidification water according to the humidification quantity to be output and the current power supply voltage, and the conductivity of the humidification water collected in the test working condition is preset conductivity. The air conditioner obtains the actual conductivity of the humidification water, and corrects the surface area according to the actual conductivity, so that the target surface area is obtained. It should be noted that, if the actual conductivity is greater than the preset conductivity, the larger the difference between the actual conductivity and the preset conductivity is, the smaller the obtained target surface area is; if the actual conductivity is less than the preset conductivity, the larger the difference between the preset conductivity and the actual conductivity, the larger the target surface area. The actual conductivity can be measured by a conductivity meter in the humidification water tank.
In the technical scheme provided by the embodiment, the air conditioner determines the target surface area of the heating electrode immersed in the humidification water by combining the current conductivity standard of the humidification water, so that the actual output humidification quantity of the air conditioner is consistent with the set humidification quantity, and the humidification effect of the air conditioner is ensured.
In one embodiment, the air conditioner is provided with a water storage tank, and the water storage tank can collect condensed water generated when the air conditioner refrigerates. The air conditioner can inject the condensed water in the water storage tank into the humidifying water tank through the water pump. When the air conditioner is used for refrigerating, the water level in the water storage tank is determined while the water storage tank collects condensate water. When the water level reaches the preset water level, a drain valve of the water storage tank is opened, and condensed water in the water storage tank is discharged, so that the situation that the indoor unit leaks water due to excessive water in the water storage tank is prevented. A water inlet box is arranged between the water storage tank and the humidifying water tank, a conductivity meter can be arranged in the water inlet box, and the detected conductivity of the humidifying water is the conductivity of the water in the water storage tank.
When the air conditioner operates in the humidifying mode, the water vapor content in the humidifying water tank is high, the temperature is high, and if the conductivity meter is arranged in the humidifying water tank, the service life of the conductivity meter can be greatly shortened. In this regard, the air conditioner may determine the conductivity in the humidification tank based on the conductivity of the water in the reservoir. Specifically, when the air conditioner starts to operate in the humidification mode, the conductivity of the humidification water in the humidification water tank is actually equal to that of the water in the water storage tank, but the ion concentration of the humidification water in the humidification water tank is increased along with the continuous humidification of the air conditioner, so that the conductivity of the humidification water is increased; the amount of humidification to be output of the air conditioner is constant, so the total amount of steam output by the air conditioner can be obtained by multiplying the continuous operation time length of the humidifying mode of the air conditioner by the amount of humidification to be output (the amount of humidification to be output is the amount of humidification output by the air conditioner per unit time); the current water level in the humidification water tank represents the current volume of the humidification water, (the current volume of the humidification water + the total amount of steam) and the ion content obtained by converting the water conductivity in the water storage tank are the ion content of the humidification water, the ion content in the humidification water tank is divided by the current volume of the humidification water to obtain the current ion concentration of the humidification water, and therefore the current conductivity of the humidification water is obtained through conversion according to the current ion concentration.
In addition, the air conditioner can acquire the initial water level in water storage tank and the humidification water tank when operation humidification mode, when the electric conductivity in the humidification water tank is confirmed to needs, acquires the current water level in water storage tank and the humidification water tank, can confirm the steam total amount that the humidification water tank exported according to the initial water level of water storage tank, the initial water level in the humidification water tank, the current water level of water storage tank and the current water level in the humidification water tank.
In the technical scheme provided by the embodiment, the air conditioner is provided with the water storage tank, water in the water storage tank is injected into the humidifying water tank through the determination water pump, the current conductivity of the humidifying water in the humidifying water tank is calculated through detecting the conductivity of the water in the water storage tank, and therefore the surface area of the heating electrode immersed into the humidifying water is accurately determined according to the current conductivity, the actual output humidification quantity of the air conditioner is consistent with the set humidification quantity, and the humidification effect of the air conditioner is guaranteed.
Referring to fig. 6, fig. 6 is another detailed flowchart of step S510 in fig. 4, where the step S510 includes:
step S514, determining the surface area of the heating electrode immersed in the humidification water according to the humidification quantity to be output and the current power supply voltage;
step S515, when it is determined that the surface area is smaller than the maximum surface area of the heating electrode, taking the surface area as a target surface area;
and step S516, when the surface area is determined to be larger than or equal to the maximum surface area of the heating electrode, taking the maximum surface area as a target surface area, wherein when the target surface area is the maximum surface area of the heating electrode, the power supply circuit is controlled to input a target power supply voltage determined by the maximum surface area to the heating electrode.
In the present embodiment, the voltage supplied to the heating electrode by the power supply circuit is constant, and therefore, when the current of the heating electrode is maximum, the amount of humidification to be output generated by the air conditioner is also maximum, and it can be understood that each power supply voltage corresponds to the maximum amount of humidification to be output. In the actual humidification process of the air conditioner, the amount of humidification to be output, which may be set by a user, is relatively large, so that the maximum amount of humidification to be output corresponding to the current power supply voltage is smaller than the amount of humidification to be output, which is set by the user, at this time, the power supply voltage output by the power supply circuit to the heating electrode needs to be increased.
For this purpose, the air conditioner firstly determines the surface area of the heating electrode immersed in the humidification water according to the set humidification quantity to be output and the current power supply voltage, and the surface area can be obtained through a conversion formula corresponding to the current power supply voltage; when the surface area is smaller than the maximum surface area of the heating electrode, it can be determined that the maximum amount of humidification to be output corresponding to the current power supply voltage is larger than the set amount of humidification to be output.
If the surface area is larger than or equal to the maximum surface area of the heating electrode, the maximum to-be-output humidification amount corresponding to the current power supply voltage can be judged to be smaller than the set to-be-output humidification amount, at the moment, the maximum surface area is used as a target surface area, the target power supply voltage is determined through the maximum surface area, and the target power supply voltage is larger than the current power supply voltage, so that the power supply circuit is controlled to input the target power supply voltage to the heating electrode.
In the technical solution provided in this embodiment, the air conditioner determines, when determining the surface area of the heating electrode immersed in the humidification water, whether the current power supply voltage of the heating electrode can output the determined amount of humidification to be output, so as to control the power supply circuit to input a suitable power supply voltage to the heating electrode according to the determination result, thereby ensuring the humidification efficiency of the air conditioner.
Referring to fig. 7, fig. 7 is a third embodiment of the humidification control method of the air conditioner according to the present invention, and based on the first embodiment, the step S200 further includes:
step S210, determining the current rotating speed of the water pump, and determining the water level variation of the water level of the humidification water tank within a preset time length according to the current rotating speed and the humidification quantity to be output;
step S220, determining the surface area variation of the heating electrode immersed in the water of the humidifying water tank according to the water level variation;
step S230, determining a target power supply voltage of the heating electrode according to the surface area variation and the current power supply voltage of the heating electrode.
In this embodiment, the humidification component includes the heating electrode, that is, the target operation parameter of the humidification component is actually the target power supply voltage of the heating electrode, that is, in this embodiment, only the voltage of the heating electrode is adjusted.
Specifically, the air conditioner determines the current rotation speed of the water pump, and the water inflow in the humidification water tank can be determined through the current rotation speed, so that the air conditioner can determine the water level variation of the humidification water tank according to the current rotation speed and the humidification amount to be output, for example, the water pump operates at the current rotation speed, the humidification water tank increases the water level by 4cm per minute, and when the air conditioner performs humidification, the humidification amount to be output determines that the humidification water tank decreases by 3cm per minute, so that the water level variation is 1cm/min, that is, the humidification water tank increases the water level by 1cm per minute. The preset time corresponding to the water level variation is 1min, and of course, other values are also possible, which is not limited herein.
The actual humidification quantity of the air conditioner is related to the current magnitude of the heating electrode, and the larger the surface area of the heating electrode immersed in the humidification water is, the larger the current is; the amount of change in the surface area is related to the amount of change in the water level, that is, the amount of change in the surface area of the heating electrode immersed in water can be determined from the amount of change in the water level, and the amount of change in the surface area can be directly converted into the amount of change in the current of the heating electrode, whereby the amount of change in the supply voltage is determined from the amount of change in the current, and the target supply voltage for the heating electrode is determined from the amount of change.
It should be noted that the water level variation and the surface area variation have a positive correlation, the surface area variation and the current variation have a positive correlation, and the current variation and the power supply voltage variation have a negative correlation, that is, when the water level variation is a negative value, the target power supply voltage of the heating electrode is greater than the current power supply voltage, and when the water level variation is a positive value, the target power supply voltage of the heating electrode is less than the current power supply voltage.
Furthermore, the air conditioner can adjust the rotation speed of the water pump or adjust the power supply voltage of the heating electrode so that the output humidification amount of the air conditioner is the determined humidification amount to be output, the air conditioner can also adjust the rotation speed of the water pump and the power supply voltage of the heating electrode at the same time, and the mode of adjusting the two humidification components at the same time can refer to the flow of independently adjusting the two humidification components, which is not repeated herein.
In the technical scheme provided by this embodiment, the air conditioner determines the current rotation speed of the water pump, determines the water level variation of the humidification water tank within a preset time period according to the current rotation speed and the amount of humidification to be output, and further determines the surface area variation of the heating electrode immersed in the humidification water according to the water level variation, thereby determining the target power supply voltage of the heating electrode according to the surface area variation, so that the air conditioner outputs the determined amount of humidification to realize clean humidification.

and step S800, when the air conditioner operates in a cooling mode, increasing the operation parameters of a target component of the air conditioner according to the to-be-output humidification quantity, wherein the operation parameters of the target component comprise at least one of the operation frequency of a compressor and the rotating speed of an indoor fan.
And S900, when the air conditioner operates in a heating mode, reducing the operation parameter of the target component of the air conditioner according to the to-be-output humidification quantity.
The steam generated by the humidifying water tank can enter the air channel, the air in the air channel absorbs the steam, and then the air enters the room, so that the room is humidified, and the air in the air channel passes through the indoor heat exchanger. Therefore, when the air conditioner operates in a refrigeration mode, air in the air duct into which steam enters is cold air after heat exchange by the indoor heat exchanger, and the cold air absorbs the steam, so that the cold output by the air conditioner is reduced; in the heating mode, the hot air absorbs the steam, which increases the heat output from the air conditioner.
Therefore, when the air conditioner operates in the humidification mode and the refrigeration mode, the output of the cooling capacity can be increased, the increased cooling capacity is determined according to the humidification capacity to be output, the larger the humidification capacity to be output is, the more the cooling capacity needs to be increased is, and the output of the cooling capacity is increased by increasing the operating frequency of the compressor and the rotating speed of the indoor fan.
And when the air conditioner operates in the humidification mode and operates in the heating mode. The output of the heat is reduced, the reduced heat is determined according to the amount of humidification to be output, the greater the amount of humidification to be output is, the more heat needs to be reduced, and the air conditioner reduces the output of the heat by reducing the operating frequency of the compressor and the rotating speed of the indoor fan.
In the technical scheme that this embodiment provided, when the air conditioner ran the humidification mode and ran the refrigeration mode, the output of control air conditioner increase cold volume to guarantee the refrigeration effect of air conditioner, at air conditioner operation humidification mode and operation heating mode, then control the air conditioner and reduce thermal output, make the air conditioner can not produce too much heat, avoid the indoor environment to be overheated environment.
In one embodiment, the humidifying water tank is provided with a cleaning device, the cleaning device can be a stirring device, and the stirring device can be a blade, and the blade is connected with the motor.

If the current conductivity of the humidification water tank is smaller than the preset conductivity, the concentration of ions in the humidification water tank is low, the humidification water tank does not need to be cleaned, at the moment, a drain valve of the humidification water tank is opened to drain water, the drain valve is closed after the drainage is finished, and a water pump is controlled to operate to inject water into the humidification water tank.
