The control method for the dehumidifier provided by the embodiment of the disclosure is applied to dehumidifier equipment at least provided with a shielding device. Here, the shielding device is arranged at an air inlet of the dehumidifier and used for adjusting the air inlet area of the dehumidifier.
With reference to fig. 1, an embodiment of the present disclosure provides a method for controlling a dehumidifier, so as to implement control of the dehumidifier, where the method includes:
and S01, acquiring the environment humidity, and determining the humidity difference value between the environment humidity and the set humidity of the dehumidifier.
Here, the ambient humidity refers to the relative humidity of the indoor air; setting humidity, namely indoor target humidity set by a user; the humidity difference is an absolute value of a difference between the ambient humidity and a set humidity of the dehumidifier.
During the operation of the dehumidifier, the relatively humid air is sucked into the dehumidifier by the fan from the air inlet of the dehumidifier, and the relatively dry air is discharged out of the dehumidifier through the heat exchanger, so that the indoor humidity is kept at the appropriate relative humidity by circulation. Therefore, the difference between the indoor air humidity and the set humidity can be obtained by acquiring the environment humidity and determining the humidity difference between the environment humidity and the set humidity of the dehumidifier, and the dehumidification amount of the dehumidifier is adjusted accordingly so as to quickly adapt to the dehumidification requirement.
And S02, determining the target air inlet area of the air inlet of the dehumidifier according to the humidity difference.
Optionally, according to the humidity difference, determining a target air inlet area of an air inlet of the dehumidifier includes: acquiring a humidity ratio of the humidity difference value to the environmental humidity; and determining a target air inlet area according to the humidity ratio.
And determining the variation of the target dehumidification capacity of the dehumidifier corresponding to the humidity difference according to the humidity difference between the environment humidity and the set humidity of the dehumidifier, wherein the correlation between the humidity difference and the variation of the target dehumidification capacity can be converted into the correlation between the humidity ratio and the target air inlet area.
Therefore, the humidity ratio is obtained according to the humidity difference value, the target air inlet area of the air inlet of the dehumidifier can be determined according to the incidence relation between the humidity ratio and the target air inlet area, and then follow-up control is carried out.
Optionally, determine the target air intake area according to the humidity ratio, include: under the condition that the humidity ratio is larger than a first threshold value, the target air inlet area is the area of the air inlet; and under the condition that the humidity ratio is smaller than or equal to the first threshold, determining the target air inlet area according to the numerical value interval where the humidity ratio is located. In some embodiments, the first threshold is 50%.
In some application scenarios, the indoor humidity may be divided into a plurality of levels, such as a first level, a second level, a third level, a fourth level, a fifth level, and so on. In this embodiment, the indoor humidity is classified into four levels, the first level being maximum, the second level being extra-large, the third level being larger, and the fourth level being moderate.
The first threshold is used to represent the current situation where the indoor humidity is extremely high. Therefore, under the condition that the humidity is greater than the first threshold value, the indoor humidity is extremely high, and the air inlet area of the dehumidifier needs to be fully opened, so that the dehumidification efficiency is improved, and the indoor humidity is reduced as soon as possible; under the condition that the air inlet area is smaller than the first threshold value, the air inlet area of the air inlet of the dehumidifier can be adjusted according to a more detailed judgment condition of the indoor humidity without reducing the indoor humidity as soon as possible.
So, compare through the size of humidity ratio and first threshold value, carry out preliminary division to the scope of target air inlet area, simplify control flow.
Optionally, according to the numerical interval that the humidity ratio value is in, determine the target air inlet area, including: under the condition that the humidity ratio is larger than a second threshold and smaller than or equal to a first threshold, the target air inlet area is a first proportion of the area of the air inlet; under the condition that the humidity ratio is larger than a third threshold and smaller than or equal to a second threshold, the target air inlet area is a second proportion of the area of the air inlet; under the condition that the humidity ratio is larger than the fourth threshold and smaller than or equal to the third threshold, the target air inlet area is the third proportion of the area of the air inlet; under the condition that the humidity ratio is smaller than or equal to a fourth threshold value, the target air inlet area is a fourth proportion of the area of the air inlet; the first threshold value is larger than the second threshold value, the second threshold value is larger than the third threshold value, and the third threshold value is larger than the fourth threshold value; the first proportion is greater than the second proportion, the second proportion is greater than the third proportion, and the third proportion is greater than the fourth proportion.
The second threshold is used for expressing the current condition of the super-large indoor humidity, so that the super-large indoor humidity needs to be adjusted to enable the air inlet area of the air inlet to be the first ratio of the air inlet area under the condition that the indoor humidity is larger than the second threshold and smaller than or equal to the first threshold, and the dehumidification efficiency is improved.
The third threshold is used for expressing the current situation of large indoor humidity, therefore, when the indoor humidity is larger than the third threshold and smaller than or equal to the second threshold, the indoor humidity is large, and the air inlet area of the air inlet needs to be adjusted to be the second proportion of the air inlet area, so as to improve the dehumidification efficiency.
The fourth threshold is used for expressing the condition that the current indoor humidity is moderate, so that the indoor humidity is moderate under the condition that the indoor humidity is greater than the fourth threshold and less than or equal to the third threshold, and the air inlet area of the air inlet needs to be adjusted to be a third proportion of the air inlet area, so that a better dehumidification effect is achieved.
Under the condition of being smaller than the fourth threshold value, the air inlet area of the air inlet needs to be adjusted to be the fourth proportion of the area of the air inlet, and the required dehumidification effect can be achieved by the smaller air inlet area.
In some embodiments, the first threshold is 50%, the second threshold is 40%, the third threshold is 30%, and the fourth threshold is 20%; the first proportion is 90%, the second proportion is 80%, the third proportion is 70%, and the fourth proportion is 60%.
Therefore, by setting a plurality of threshold values, the threshold value interval where the humidity ratio value is located is judged, the ratio of the target air inlet area to the air inlet area is further determined according to the incidence relation between the humidity ratio value and the target air inlet area, and the larger the humidity ratio value is, the larger the ratio of the target air inlet area to the air inlet area is, so that the determination of the target air inlet area can more accurately reflect the environment humidity condition.
And S03, adjusting the shielding area of the shielding device at the air inlet according to the area difference value between the target air inlet area and the current air inlet area, and further adjusting the air inlet area of the air inlet.
Here, the area difference is the difference between the target air inlet area and the current air inlet area; the shielding area refers to the area of the air inlet which is shielded by the shielding device and can not be passed by air; the shielding device is arranged at an air inlet of the dehumidifier.
According to the area difference value of the target air inlet area and the current air inlet area, the shielding area of the shielding device at the air inlet is adjusted, and then the air inlet area of the air inlet is adjusted, so that the dehumidifying equipment can exert larger capacity, the dehumidifying efficiency is improved, and a better dehumidifying effect can be achieved.
Alternatively, as shown in the connection relation diagram of fig. 2 and the schematic structure diagram of fig. 3, the shielding device includes a motor 11, a rotating shaft 12 connected to the motor 11, and a curtain 13 rolled on the rotating shaft 12; here, the rotary shaft 12 is provided with a curtain 13 and is arranged at one end of an air inlet grid of an air inlet of the dehumidifier through a connecting device, and the motor 11 is arranged at one end of the rotary shaft 12. When the motor 11 is powered on to rotate, the rotating shaft 12 is driven to rotate the blocking curtain 13 to extend out of the rotating shaft 12 or retract into the rotating shaft 12, so that the blocking area of the blocking curtain 13 on the air inlet grille is changed, and the air inlet area is adjusted.
Based on above-mentioned structure, according to the area difference of target air inlet area and current air inlet area, adjust the area that shelters from of sheltering from the device at the air intake, and then adjust the air inlet area of air intake, include: determining the steering of the motor and the rotation time length of the motor according to the area difference; the control motor rotates according to the steering and rotating duration to drive the stop curtain to extend out of the rotating shaft or retract into the rotating shaft.
For example, when the area difference is a positive number, the motor is turned in a direction in which the intake air area can be increased, and when the area difference is a negative number, the motor is turned in a direction in which the intake air area can be decreased.
For another example, the rotation time length of the motor is determined according to the absolute value of the area difference; the larger the absolute value of the area difference is, the longer the rotation time period of the motor is.
Therefore, the shielding device is connected with the dehumidifier through the motor, when the motor rotates, the rotating shaft drives the blocking curtain wound on the rotating shaft to extend or shorten the blocking curtain, the air inlet area of the air inlet is adjusted through the covering change of the blocking curtain on the area of the air inlet, the change of the air inlet amount of the dehumidifier is realized, and the air inlet amount directly influences the dehumidification amount of the dehumidifier, so that the aim of adjusting the dehumidification amount of the dehumidifier according to the environmental humidity is fulfilled.
Optionally, after adjusting the air inlet area of air intake, still include:
acquiring the change rate of the indoor humidity after a set time length; and under the condition that the indoor humidity change rate is greater than or equal to the set rate, controlling the shielding device to keep the shielding area of the air inlet.
Therefore, under the condition that the indoor humidity change rate is greater than or equal to the set rate, the current dehumidification effect is better, and the air inlet area is more appropriate. Under the condition, the current air inlet area is not changed, the dehumidifier continues to operate according to the current air inlet area, the operation times of the shielding device can be reduced, the power consumption is reduced, and the service life of the dehumidifier is prolonged.
Under the condition that the indoor humidity change rate is smaller than the set rate, the shielding device is controlled to move towards the direction of reducing the shielding area so as to increase the air inlet area of the air inlet. Therefore, under the condition that the indoor humidity change rate is smaller than the set rate, the current dehumidification effect is not obvious, and the dehumidification quantity corresponding to the current air inlet area of the dehumidifier cannot reach the dehumidification quantity required by the set humidity. Under the condition, the air inlet area of the air inlet is increased, the dehumidification efficiency can be improved, and the target dehumidification capacity can be achieved more quickly.
Here, the set time period is a preset time period during which the dehumidifier operates to change the ambient humidity to a certain extent. The set rate is the change rate of the indoor humidity in the dehumidification process under the condition of meeting the comfort of a user.
Specifically, the set rate may be determined based on the humidity difference. Setting the speed to be a first speed under the condition that the humidity difference value is larger than a first set value; setting the speed as a second speed under the condition that the humidity difference value is larger than a second set value and is smaller than or equal to a first set value; setting the rate as a third rate under the condition that the humidity difference value is larger than a third set value and smaller than or equal to a second set value; setting the rate as a fourth rate under the condition that the humidity difference value is greater than a fourth set value and less than or equal to a third set value; and setting the speed as a fourth speed under the condition that the humidity difference value is greater than a fifth set value and less than or equal to a fourth set value. Wherein the first rate is less than the second rate, the second rate is less than the third rate, and the third rate is less than the fourth rate.
Optionally, the dehumidifier is controlled to stop when the humidity difference between the ambient humidity and the set humidity of the dehumidifier is less than a set threshold.
Here, the set threshold value is used to reflect that the dehumidification effect has substantially reached the dehumidification demand corresponding to the set humidity.
Therefore, when the humidity difference value between the environment humidity and the set humidity of the dehumidifier is smaller than the set threshold value, the dehumidification effect of the dehumidifier is achieved, and the dehumidifier can stop dehumidifying.
By adopting the control method for the dehumidifier, provided by the embodiment of the disclosure, when the environmental humidity is greatly changed, the air inlet area of the air inlet is changed through the shielding device arranged at the air inlet of the dehumidifier, the air inlet quantity of the dehumidifier is changed, and the dehumidification capacity of the dehumidifier in the same time is further changed, so that the dehumidification equipment can exert higher capacity, the dehumidification efficiency is improved, and a better dehumidification effect is achieved. Through this scheme, the user has better use when using the dehumidifier and experiences, and the dehumidification effect is better.
With reference to fig. 4, an embodiment of the present disclosure provides a control device for a dehumidifier, where the control device controls the dehumidifier by using the control method disclosed in the above embodiment, and the device specifically includes: an acquisition unit 21, a calculation unit 22 and an adjustment unit 23.
