Detailed Description
The present embodiment first provides a method for controlling an air conditioner, in which an indoor unit of the air conditioner includes a casing, an outer air guiding plate, and an inner air guiding plate. The lower part of the front side of the shell is limited with an air outlet extending along the transverse direction, the outer air deflector is rotatably arranged on the shell to open or close the air outlet, and the inner air deflector is positioned at the inner side of the outer air deflector and rotatably arranged at the air outlet.
The indoor unit of this embodiment may be a wall-mounted indoor unit, and the lateral direction refers to a longitudinal direction of the casing.
The outer air deflector can be controlled to rotate to completely open the air outlet, at the moment, the position of the outer air deflector can be recorded as the maximum rotating position of the outer air deflector, the outer air deflector can be controlled to rotate to completely cover the air outlet, and the inner air deflector rotates to be completely positioned on the inner side of the outer air deflector, so that the air outlet is in a closed state.
In the process of refrigerating operation of the air conditioner, in order to avoid cold air from directly blowing to a human body and causing discomfort of the human body, the outer air guide plate can be configured to rotate to the first position, the inner air guide plate can be configured to rotate to the second position, the outer air guide plate at the first position and the inner air guide plate at the second position guide the air outlet flow of the air outlet together, so that the cold air at the air outlet flows to the front or the front upper part of the indoor unit to be led out, the cold air flow is prevented from directly blowing to the human body downwards, and the operation mode is marked as a refrigerating no-blowing air supply mode of the indoor unit. The user can adjust the air conditioner into a refrigeration and no-blowing air supply mode through a remote controller of the air conditioner.
Fig. 1 is a schematic flowchart of a control method of an air conditioner according to an embodiment of the present invention
Specifically, as shown in fig. 1, the control method of the air conditioner may include:
s102: when the air conditioner is started to work, acquiring a setting mode of a user on the air conditioner;
s104: judging whether the set mode is a refrigeration and no-blowing air supply mode;
s106: if the set mode is a refrigeration and no-blowing air supply mode, the inner air guide plate is adjusted to rotate to the second position, and the outer air guide plate is adjusted to rotate to the first position according to indoor environment information of the indoor unit and operation information of the outer air guide plate;
s108: if the setting mode is not the refrigeration and no-blowing air supply mode, the inner air guide plate is adjusted to rotate to the second position according to the indoor environment information, the user setting information and the operation information of the air conditioner, and the outer air guide plate is adjusted to rotate to the first position according to the indoor environment information, the user setting information, the operation information of the air conditioner and the operation information of the outer air guide plate.
After step S104, the control method of the air conditioner is divided into two cases, the first case is: if a user starts the air conditioner, the operation mode of the air conditioner is set to be a refrigerating and non-blowing air supply mode, at the moment, the inner air deflector is adjusted to rotate to the second position, and the time when the outer air deflector rotates to the first position needs to be determined according to indoor environment information of the indoor unit and operation information of the outer air deflector; the second case is: if the user starts the air conditioner, the operation mode of the air conditioner is set to other operation modes before the air supply mode without blowing the air for cooling, such as a heating mode, a dehumidifying mode, a sleeping mode, a self-cleaning mode and the like, and at the moment, the time when the inner air deflector rotates to the second position needs to be determined according to the environment information of the indoor unit, the user setting information and the operation information of the air conditioner; the time when the outer air deflector rotates to the first position is determined according to the operation information of the air conditioner and the operation information of the outer air deflector. That is, if a user starts the air conditioner, the operation mode of the air conditioner is set to be other operation modes before the cooling and non-blowing air supply mode, the air conditioner operates in the mode set by the user, at this time, the position of the outer air deflector and the position of the inner air deflector correspond to the mode set by the user, and it can be understood that each operation mode of the air conditioner corresponds to the position of the outer air deflector and the position of the inner air deflector, when a certain condition is met, the outer air deflector can rotate to the first position, and when the certain condition is met, the inner air deflector can rotate to the second position, so that the air conditioner operates in the cooling and non-blowing air supply mode.
The indoor environment information may be indoor temperature, indoor humidity, etc., the operation information of the external air deflector may be time for the external air deflector to be adjusted to rotate to the first position each time in the operation process of the air conditioner when the air conditioner is started up each time, the user setting information may be setting temperature input by a user when the air conditioner is started up, etc., and the operation information of the air conditioner may be continuous operation time of the air conditioner after the air conditioner is started up each time.
The control method of the air conditioner further comprises the step of obtaining the parameters, and specifically comprises the following steps: collecting indoor humidity and indoor temperature; acquiring a set temperature input by a user when the user starts up; recording the time when the outer air deflector is adjusted to rotate to the first position each time; and recording the continuous operation time of the air conditioner after each startup. After the air conditioner is started, the air conditioner can collect indoor humidity and indoor temperature in real time.
As in step S106, if the setting mode of the air conditioner by the user is the cooling and non-blowing air supply mode, the step of adjusting the outer air guide plate to rotate to the first position according to the indoor environment information of the indoor unit and the operation information of the outer air guide plate may specifically include:
when the following conditions are met, the outer air deflector is adjusted to rotate to a first position;
the indoor humidity is smaller than a first humidity threshold value within a first continuous preset time period;
the time interval between the first time and the last time that the outer air deflector is adjusted to rotate to the first position is longer than the first preset time interval.
The above process can also be understood as that when the user sets the air conditioner to the cooling and no-blowing mode, the inner air deflector is adjusted to rotate to the second position, and the adjustment of the outer air deflector needs to satisfy the above two conditions, namely: when the indoor humidity is less than the first humidity threshold value within the continuous first preset time period and the time interval between the indoor humidity and the last time that the outer air deflector is adjusted to rotate to the first position is greater than the first preset interval time, the outer air deflector can be adjusted to rotate to the first position, and at the moment, the air conditioner enters a refrigeration and no-blowing air supply mode.
If the time that the outer air guide plate is adjusted to rotate to the first position for the first time is determined after the air conditioner is started at this time, the time that the outer air guide plate is adjusted to rotate to the first position for the last time is the time that the outer air guide plate is adjusted to rotate to the first position for the last time in the previous starting operation process of the air conditioner. If the time that the nth (n is more than 1) time of the outer air deflector is adjusted to rotate to the first position is determined in the process of the current starting operation of the air conditioner, the time that the outer air deflector is adjusted to rotate to the first position last time is the time that the outer air deflector is adjusted to rotate to the first position last time in the process of the current starting operation of the air conditioner.
When the inner air deflector participates in air guiding, generally, two surfaces of the inner air deflector both participate in air guiding, when the outer air deflector is located at the first position, the flow direction of air flow at the air outlet is guided, cold air flow at the air outlet is changed in direction through the air guiding surface of the outer air deflector, the temperature of the air guiding surface of the outer air deflector is higher than that of the cold air flow, when the air guiding surface of the outer air deflector contacts with the cold air flow, condensation is easily formed on the outer air deflector, and the larger the humidity is, the more the condensation is easily formed on the outer air deflector. Therefore, in the control method of this embodiment, the indoor humidity needs to meet the condition that the indoor humidity is smaller than the first humidity threshold within the continuous first preset time period, which indicates that the indoor humidity is relatively small, the outer air guide plate is not prone to forming condensation, and at this time, the outer air guide plate can be rotated to the first position. Therefore, the time for rotating the outer air guide plate to the first position is controlled according to the change of the indoor humidity, the comfortable air supply performance of the air conditioner is improved, and meanwhile condensation formed on the outer air guide plate is avoided.
Meanwhile, the time when the outer air guide plate rotates to the first position is determined according to the time interval between the time when the outer air guide plate is adjusted to rotate to the first position last time, and condensation of the outer air guide plate caused by the fact that the outer air guide plate is frequently located at the first position is avoided. Therefore, the time when the outer air deflector is adjusted to the first position at this time is determined together with the time interval when the indoor humidity and the outer air deflector are adjusted to rotate to the first position last time, so that the more reasonable time for the air conditioner to supply air comfortably is determined, and meanwhile, condensation formed on the outer air deflector is avoided.
In step S106, after the inner air guiding plate is adjusted to rotate to the second position, if the operation mode of the air conditioner is switched to the non-cooling mode, the user cancels the cooling and non-blowing air supply mode through the remote controller, or the operation mode of the air conditioner is switched to the self-cleaning mode, during the operation process of the air conditioner, the air conditioner adjusts the inner air guiding plate from the state of being at the second position to another position. The other positions of the inner air deflector can be different from the other positions of the second position in the rotation range of the inner air deflector, and are determined according to the operation mode switched by the air conditioner.
As mentioned above, in step S106, after the step of adjusting the outer air guiding plate to rotate to the first position according to the indoor environment information of the indoor unit and the operation information of the outer air guiding plate, the method further includes:
when the indoor humidity is greater than a second humidity threshold value within a second preset time period, adjusting the position of the outer air deflector at the first position to finish the refrigeration and non-blowing air supply mode;
wherein the second humidity threshold is greater than or equal to the first humidity threshold.
That is to say, when the indoor humidity is greater than the second humidity threshold value within a continuous period of time, the position of the outer air deflector is adjusted from the current first position to other positions, so that the air conditioner is no longer in the cooling and non-blowing air supply mode.
It can be understood that, if the operation mode of the air conditioner is switched to the non-cooling mode, the user cancels the cooling and non-blowing air supply mode through the remote controller, or the operation mode of the air conditioner is switched to the self-cleaning mode, etc., the position of the outer air deflector is also adjusted from the current first position to other positions, so that the air conditioner is adjusted from the current cooling and non-blowing air supply mode to other corresponding modes. The other positions of the outer air deflector can be the maximum positions where the outer air deflector rotates to fully open the air outlet, or can be other positions in the rotatable range of the outer air deflector, and the specific rotating position of the outer air deflector corresponds to the switching operation mode of the air conditioner.
In step S108, if the setting mode of the air conditioner is not the cooling and non-blowing mode when the user starts the air conditioner, the timing when the inner air guiding plate rotates to the second position needs to satisfy a certain condition, and the timing when the outer air guiding plate rotates to the first position also needs to satisfy a certain condition.
Specifically, the step of adjusting the inner air deflector to rotate to the second position according to the indoor environment information, the user setting information and the operation information of the air conditioner specifically comprises:
when the following conditions are met, the inner air deflector is adjusted to rotate to a second position;
the difference value between the indoor temperature and the set temperature is smaller than a first preset temperature difference value;
the indoor humidity is less than a third humidity threshold;
the continuous operation time of the air conditioner after the starting is larger than or equal to the preset operation time.
When a user starts the air conditioner, the setting mode of the air conditioner is not a refrigeration and no-blowing air supply mode, and the inner air deflector can rotate to the second position when the three conditions are met in the running process of the air conditioner.
Further, the step of adjusting the outer air guide plate to rotate to the first position according to the indoor environment information, the user setting information, the operation information of the air conditioner and the operation information of the outer air guide plate specifically comprises:
when the following conditions are met, the outer air deflector is adjusted to rotate to a first position;
the difference value between the indoor temperature and the set temperature is smaller than a second preset temperature difference value;
the indoor humidity is less than a fourth humidity threshold;
the continuous operation time of the air conditioner after the starting is larger than or equal to the preset operation time;
the time interval between the first time and the last time that the outer air deflector is adjusted to rotate to the first position is longer than the second preset time interval;
and the second preset temperature difference value is equal to or smaller than the first preset temperature difference value, and the fourth humidity threshold value is smaller than the third humidity threshold value.
When a user starts the air conditioner, the setting mode of the air conditioner is not a refrigeration and no-blowing air supply mode, and the outer air deflector can rotate to the first position when the four conditions are met in the running process of the air conditioner. When the inner air deflector rotates to the second position, the outer air deflector rotates to the first position, and the air conditioner operates in a refrigeration and no-blowing air supply mode.
As described above, if the time that the outer air guiding plate is adjusted to rotate to the first position for the first time is determined after the air conditioner is turned on this time, the time that the outer air guiding plate is adjusted to rotate to the first position for the last time is the time that the outer air guiding plate is adjusted to rotate to the first position for the last time in the previous turning-on operation process of the air conditioner. If the time that the nth (n is more than 1) time of the outer air deflector is adjusted to rotate to the first position is determined in the process of the current starting operation of the air conditioner, the time that the outer air deflector is adjusted to rotate to the first position last time is the time that the outer air deflector is adjusted to rotate to the first position last time in the process of the current starting operation of the air conditioner.
In the control method of the air conditioner of this embodiment, one of the preconditions for the outer air guiding plate to rotate to the first position is that the indoor humidity is smaller than a fourth humidity threshold, and one of the preconditions for the inner air guiding plate to rotate to the second position is that the indoor humidity is smaller than a third humidity threshold, where the fourth humidity threshold is smaller than the third humidity threshold, which indicates that the outer air guiding plate can be adjusted to the first position under the condition that the indoor humidity is relatively low, so as to avoid the formation of condensation when the outer air guiding plate is in a high humidity environment at the first position.
Meanwhile, the determination of the time when the outer air guide plate rotates to the first position is related to the time interval when the outer air guide plate is adjusted to rotate to the first position last time, so that the phenomenon that the outer air guide plate is frequently located at the first position to cause condensation of the outer air guide plate is avoided. Therefore, the time when the outer air deflector is adjusted to the first position at this time is determined together with the time interval when the indoor humidity and the outer air deflector are adjusted to rotate to the first position last time, so that the more reasonable time for the air conditioner to supply air comfortably is determined, and meanwhile, condensation formed on the outer air deflector is avoided.
The determination of the time when the inner air deflector rotates to the second position and the determination of the time when the outer air deflector rotates to the first position are also related to the difference between the continuous operation time after the air conditioner is started and the indoor temperature and the temperature set by the user, so as to ensure that the air conditioner operates to adjust the indoor temperature to a relatively proper temperature.
As mentioned above in step S108, when the setting mode of the air conditioner is not the cooling and no-blowing air supply mode when the user starts the air conditioner, after the step of adjusting the inner air guiding plate to rotate to the second position according to the indoor environment information, the user setting information and the operation information of the air conditioner, the method further includes:
adjusting the position of the inner air deflector at the second position to finish the refrigeration and no-blowing air supply mode under any one of the following conditions;
the difference value between the indoor temperature and the set temperature is greater than a third preset temperature difference value;
the indoor humidity is greater than a fifth humidity threshold;
and the third preset temperature difference value is equal to or greater than the first preset temperature difference value, and the fifth humidity threshold value is equal to or greater than the third humidity threshold value.
That is, when the two conditions are met, the position of the inner air deflector is adjusted from the current second position to other positions, so that the air conditioner is no longer in a cooling and non-blowing air supply mode.
