Fig. 1 is a schematic flowchart of a control method for an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the process for air conditioning control includes:
step 101: and controlling a guide plate of the air conditioner to run to a preset direct blowing prevention position according to the received direct blowing prevention control instruction.
Through wireless short-distance communication technology, the air conditioner can receive the anti-blow-through control instruction, for example: through infrared or bluetooth, receive the anti-blow-through control instruction that the remote control terminal sent, perhaps, through LAN WIFI technique, receive the anti-blow-through control instruction that the terminal that disposes control application APP sent. After receiving the anti-blow-through control instruction, the anti-blow-through function of air conditioner is opened, and the air conditioner is in the anti-blow-through mode operation, and the operation process can include: and controlling a guide plate of the air conditioner to run to a preset direct blowing prevention position.
In some embodiments, the air conditioner is not equipped with a humidity detection device, such as: there is not humidity transducer, perhaps, the air conditioner does not pass through indoor temperature value, dew point temperature value, obtains indoor humidity value, and indoor humidity value is not gathered to the air conditioner promptly to, do not include indoor humidity value in the indoor environment parameter value that the air conditioner gathered, like this, receive and prevent directly blowing control command after, can directly move the baffle of air conditioner to predetermineeing and prevent directly blowing the position, when the baffle is in predetermineeing and prevents directly blowing the position, the air-out of air conditioner can not directly blow to user's health, improves user experience.
In some embodiments, the air conditioner may collect an indoor humidity value, that is, the indoor environment parameter value collected by the air conditioner includes an indoor humidity value, so that after receiving the direct blowing prevention control instruction, a corresponding initial indoor temperature value and an initial indoor humidity value may be obtained, that is, an initial indoor temperature value and an initial indoor humidity value corresponding to a moment when the direct blowing prevention control instruction is received are determined. Controlling a guide plate of an air conditioner to move to a preset blow-through prevention position comprises: determining an initial indoor temperature value and an initial indoor humidity value corresponding to the moment when the anti-direct-blowing control instruction is received; controlling the guide plate to run to a first preset direct blowing prevention position under the condition that the initial indoor humidity value is greater than or equal to a preset humidity value or a second temperature absolute difference value between the initial indoor temperature value and the preset temperature value is greater than or equal to a second set temperature value; and under the condition that the initial indoor humidity value is smaller than the preset humidity value and the second temperature absolute difference value is smaller than a second set temperature value, controlling the guide plate to run to a second preset direct blowing prevention position. As can be seen, the anti-blowthrough position may include: the device comprises a first preset direct blow preventing position and a second preset direct blow preventing position, wherein an opening between guide plates corresponding to the first preset direct blow preventing position is larger than an opening between guide plates corresponding to the second preset direct blow preventing position.
For example: preset temperature value Ts configured in advance, and second set temperature value t 2 And the preset humidity value may be 70%, and table 1 is a corresponding relationship between a temperature and humidity range and a position of the guide plate provided in the embodiment of the present disclosure.
| Temperature and humidity range | Position of guide plate |
| % RH is not less than 70%, or-Tr-Ts-t is not less than t 2 ℃ | First preset blow-through preventing position |
| ％RH<70%, and | Tr-Ts | < t 2 ℃ | Second preset blow-through preventing position |
TABLE 1
Wherein,% RH is the detected indoor humidity value, tr is the detected indoor temperature value, and the opening between the guide plates corresponding to the first preset direct blow preventing position is larger than the opening between the guide plates corresponding to the second preset direct blow preventing position. Thus, when the direct-blowing prevention control instruction is received, the corresponding initial indoor temperature value and initial indoor humidity value can be obtained, namely at the moment,% RH is the initial indoor humidity value, tr is the initial indoor temperature value, so that according to the initial indoor humidity value, the initial indoor temperature value and the preset temperature value Ts, the second set temperature value is t 2 The preset humidity value is 70%, and the corresponding position of the guide plate can be determined through table 1, and thus, the guide plate is moved to the corresponding position of the guide plate.
Therefore, no matter whether the air conditioner collects the indoor humidity value or not, when the direct blowing prevention control instruction is received, the guide plate of the air conditioner can be controlled to operate to the corresponding preset direct blowing prevention position, and the initial indoor temperature value corresponding to the operation time when the air conditioner enters the direct blowing prevention mode can be obtained.
Step 102: and acquiring current indoor and outdoor environment parameter values of the air conditioner running in the anti-blow-through mode.
And the air conditioner starts the direct blowing prevention function according to the received direct blowing prevention control instruction, so that the air conditioner is operated in a direct blowing prevention mode. And in the process that the air conditioner runs in the anti-direct-blowing mode, the indoor and outdoor environmental parameter values of the air conditioner can be collected in real time or at regular time, and the method comprises the following steps: one, two or more of an indoor temperature value, an indoor humidity value, an outdoor temperature value, an indoor fan rotation speed, an operating frequency of a compressor, and the like.
In the implementation of the present disclosure, the corresponding current indoor and outdoor environment parameter values may be obtained from the collected indoor and outdoor environment parameter values at regular time, for example, the corresponding current indoor and outdoor environment parameter values may be obtained at intervals of T time. The current indoor and outdoor environment parameter values include: one, two or more of a current indoor temperature value, a current indoor humidity value, a current outdoor temperature value, a current indoor fan rotation speed, a current compressor operation frequency, and the like.
Step 103: and when the current indoor and outdoor environment parameter values meet the set conditions, controlling the guide plate to run to a preset condensation prevention position.
The air conditioner can adjust the operation parameters of one or more devices such as a compressor, an indoor and outdoor fan, an expansion valve and the like according to the indoor and outdoor environmental parameter values, thereby realizing multiple functions of refrigeration, heating, dehumidification and the like of the air conditioner.
In the embodiment of the disclosure, the running position of the guide plate can be adjusted according to the obtained current indoor and outdoor environment parameter value, so that the switching between the direct blowing prevention position and the condensation prevention position is realized.
In some embodiments, under the condition that the current indoor and outdoor environment parameter value does not include the current indoor humidity value, if a compressor of the air conditioner is not in a proportional-integral-derivative (PID) control state, obtaining a first temperature difference value between an initial indoor temperature value and a current indoor temperature value in the current indoor and outdoor environment parameter value, wherein the initial indoor temperature value is an indoor temperature value corresponding to the moment when the direct-blowing prevention control instruction is received; and controlling the guide plate to move to a preset condensation preventing position under the condition that the first temperature difference value is smaller than or equal to a first set temperature value.
The air conditioner does not collect the indoor humidity value, therefore, the current indoor and outdoor environment parameter value does not include the current indoor humidity value, after the direct-blowing prevention control instruction is received, the guide plate of the air conditioner operates to the preset direct-blowing prevention position, and the indoor temperature value corresponding to the moment when the direct-blowing prevention control instruction is received is also collected, namely the initial indoor temperature value, at the moment, the air conditioner operates according to the current indoor and outdoor environment parameter value, if the current indoor temperature value is close to the target temperature value of the air conditioner, at the moment, the compressor of the air conditioner can perform proportional-integral-derivative PID control, and when the difference between the current indoor temperature value and the target temperature value of the air conditioner is large, the compressor of the air conditioner does not perform PID control.
And under the condition that the compressor of the air conditioner is not in the PID control state, if the first temperature difference value between the initial indoor temperature value Tai0 and the current indoor temperature value Tai is less than or equal to the first set temperature value t 1 When, i.e. Tai0-Tai ≦ t 1 In the process, the guide plate can be controlled to run to the preset anti-condensation position, so that the guide plate can be automatically switched from the anti-direct-blowing position to the anti-condensation position, the generation of condensation can be reduced, the probability of water blowing and dripping phenomena is reduced, and the performance of the air conditioner is improved.
Of course, if the first temperature difference between the initial indoor temperature value Tai0 and the current indoor temperature value Tai is greater than the first set temperature value t 1 When it is, i.e. Tai0-Tai>t 1 During the time, steerable baffle moves to predetermineeing and prevents the blow-through position, has realized the baffle from preventing the automatic switch-over of condensation position to preventing the blow-through position equally, has improved the performance of air conditioner, has also improved user's experience.
In some embodiments, when the compressor of the air conditioner is in the PID control state, the current indoor temperature value is already close to the target temperature value of the air conditioner, and at this time, it is only necessary to keep the guide plate of the air conditioner at the preset blow-through prevention position.
If the air conditioner has configured humidity detection device, perhaps, accessible indoor temperature value, dew point temperature value obtain indoor humidity value, indoor humidity value has been gathered to the air conditioner promptly, and at this moment, current indoor outer environmental parameter value satisfies the settlement condition and can include: and under the condition that the current indoor and outdoor environment parameter values comprise the current outdoor humidity value and the current outdoor humidity value is greater than or equal to the preset humidity value, determining that the set condition is met, and directly controlling the guide plate to run at the preset opening position. The guide plates are opened, and the generation of condensation can be further prevented. That is, in the embodiment of the present disclosure, the preset opening position is a preset anti-condensation position.
Accordingly, in some embodiments, controlling the guide plate to travel to the preset condensation prevention position includes: updating the recorded first duration time under the condition that the current indoor and outdoor environment parameter values comprise a current outdoor humidity value and the current outdoor humidity value is greater than or equal to a preset humidity value; and under the condition that the first duration is longer than the set time, controlling the guide plate to move to a preset opening position for preventing condensation. Under the condition that the duration of the current outdoor humidity value is greater than or equal to the preset humidity value and is greater than the set time, the guide plate can be controlled to move to the preset opening position for preventing condensation. Thus, the guide plate is automatically switched from the direct blowing prevention position to the condensation prevention position.
Of course, the guide plate can be automatically switched from the condensation preventing position to the direct blowing preventing position. In some embodiments, further comprising: under the condition that the current outdoor humidity value is smaller than the preset humidity value and a third temperature absolute difference value between the current indoor temperature value and the preset temperature value in the current indoor and outdoor environment parameter values is larger than or equal to a second set temperature value, the recorded second duration is updated, and under the condition that the second duration is larger than the set time, the guide plate is controlled to run to a first preset direct blowing prevention position; and under the condition that the current outdoor humidity value is smaller than the preset humidity value and the third temperature absolute difference value is smaller than a second set temperature value, updating the recorded third duration, and under the condition that the third duration is longer than the set time, controlling the guide plate to run to a second preset direct blowing prevention position.
Table 2 is a corresponding relationship between the temperature and humidity range and the position of the guide plate provided in the embodiment of the present disclosure.
| Temperature and humidity range and duration | Position of guide plate |
| ％RH<70% and-Tr-Ts-t ≥ t 2 DEG C, duration>5min | The first preset blow-through preventing position |
| ％RH<70% and | Tr-Ts | < t 2 DEG C, duration>5min | Second preset blow-through preventing position |
| % RH ≥ 70%, duration>5min | Preset open position |
TABLE 2
Wherein,% RH is the detected indoor humidity value, and Tr is the detected indoor temperature value, so that after the air conditioner is operated in the direct blowing prevention mode, the current indoor humidity value collected by timing T can be% RH, and the collected current indoor temperature value is Tr, so that according to the current indoor humidity value, the current indoor temperature value and the preset temperature value Ts, the second set temperature value is T 2 The preset humidity value is 70%, and the corresponding guide plate position can be determined through table 2, so that the guide plate is moved to the corresponding guide plate position.
It can be seen that, in this embodiment, the air conditioner is in the operation back of preventing the direct-blowing mode, can withdraw from automatically according to the current indoor and outdoor environmental parameter value of air conditioner and prevent the direct-blowing mode, can move the baffle to the preset condensation position of preventing, like this, has not only realized automatic nimble direct-blowing control of preventing to, still, can reduce the probability of preventing the direct-blowing in-process and producing the condensation, improved the air conditioner performance, also further improved user experience.
Of course, in some embodiments, the air conditioner may not only automatically switch the position of the guide plate, but may also control the operation of one or both of the compressor, the indoor fan, and the like.
When the air conditioner does not collect the indoor humidity value, the current indoor and outdoor environmental parameter values obtained include: the current outdoor temperature value, the current indoor fan rotating speed and the current operating frequency of the compressor, wherein the current operating frequency can be matched with an air conditioner operating mode and is generally obtained through non-PID or PID control calculation. Thus, it further comprises: determining a current first matching compressor frequency matched with a current outdoor temperature value and a current indoor fan rotating speed in current indoor and outdoor environment parameter values; and controlling the operation of the air conditioner compressor according to the minimum value of the current first matched compressor frequency and the current operation frequency matched with the air conditioner operation mode.
Table 3 shows a correspondence between the outdoor temperature, the indoor fan rotation speed, and the compressor operating frequency provided in the embodiment of the present disclosure.

Thus, if the current outdoor temperature value is 30 ℃ and the current indoor fan rotating speed is matched with the highest gear wind speed of the indoor fan, the current first matched compressor frequency is determined to be the working frequency 1 according to the table 3, then the working frequency 1 is compared with the current running frequency matched with the air conditioner running mode, the minimum value is determined to be the working frequency of the compressor, and the running of the air conditioner compressor is controlled according to the minimum value.
Indoor humidity value is gathered to the air conditioner, and the current indoor outer environmental parameter value that acquires includes: the current indoor humidity value, the current outdoor temperature value, the current indoor fan rotation speed, and the current operating frequency of the compressor, wherein the current operating frequency may be matched with an air conditioner operating mode, generally calculated by non-PID or PID control. Therefore, the rotating speed of an indoor fan of the air conditioner and the running frequency of the compressor can be adjusted.
In some embodiments, a current matching indoor fan speed that matches the current indoor humidity value is determined; and controlling the indoor fan to operate according to the maximum value of the rotating speed of the currently matched indoor fan and the rotating speed of the currently matched indoor fan matched with the automatic wind state of the air conditioner. The obtained current indoor and outdoor environment parameter values can include the current indoor fan rotating speed matched with the automatic wind state of the air conditioner.
And under the condition that the air conditioner is in an automatic air state, the current indoor fan rotating speed is obtained. And the current matching indoor fan rotating speed matched with the current indoor humidity value can be determined according to the corresponding relation between the stored indoor humidity value and the indoor fan rotating speed.
Fig. 2 is a schematic diagram of a corresponding relationship between an indoor humidity value and an indoor fan rotation speed provided by an embodiment of the present disclosure. Where a =85, b =70, δ =5, the current matching indoor fan speed that matches the current indoor humidity value may be determined from fig. 2. And then, comparing the rotating speed of the current matching indoor fan with the rotating speed of the current indoor fan to obtain the maximum value, and controlling the indoor fan to operate according to the maximum value.
In some embodiments, the process of climate control further comprises: determining current second matching compressor frequencies respectively corresponding to the current outdoor temperature value, the current indoor fan rotating speed and the current position corresponding to the guide plate in the current indoor and outdoor environment parameter values; and controlling the operation of the air conditioner compressor according to the minimum value of the current second matched compressor frequency and the current operation frequency matched with the air conditioner operation mode.
The corresponding relations between the outdoor temperature value, the indoor fan rotating speed and the position corresponding to the guide plate and the working frequency of the compressor are stored, so that the current second matching compressor frequency respectively corresponding to the current outdoor temperature value, the current indoor fan rotating speed and the current position corresponding to the guide plate can be determined according to the stored corresponding relations.
Table 4 is a corresponding relationship between the outdoor temperature value, the indoor fan rotation speed, and the position corresponding to the guide plate and the compressor operating frequency provided by the embodiment of the present disclosure.
TABLE 4
The working frequency 3, the working frequency 33, the working frequency 4, the working frequency 44, the working frequency 5, the working frequency 55, the working frequency 6, and the working frequency 66 may be determined according to the performance of the air conditioner, the geographical area where the air conditioner is located, and the like, and may be stored in advance. Thus, if the current outdoor temperature is 28 ℃, the guide plate is located at the second direct blowing prevention position, and the current indoor fan rotating speed is matched with the lowest gear wind speed of the indoor fan, the second matching compressor frequency can be determined as the working frequency 66, then the working frequency 66 is compared with the current running frequency matched with the air conditioner running mode, the minimum value is determined as the working frequency of the compressor, and the running of the air conditioner compressor is controlled according to the minimum value.
It can be seen that, in the air conditioner prevent directly blowing control process, not only can realize the baffle in preventing directly blowing the position and preventing the automatic switch-over between the condensation position, also can adjust one or two kinds in indoor fan rotational speed and the compressor operating frequency, improved the performance of air conditioner, also improved user experience.
