The air conditioner comprises an indoor unit, wherein the indoor unit comprises a shell and a wind shielding device arranged on the shell, the shell is provided with an air outlet, and the wind shielding device can block wind discharged from the air outlet and prevent the wind from directly blowing to a user.
Based on the air conditioner, the invention provides a control method for the air conditioner.
The control method of the invention comprises the following steps: in the process of the air conditioner executing the self-cleaning mode, the wind shielding device shields the air outlet.
In the process of the air conditioner performing the self-cleaning mode, the dust discharged from the air outlet can be prevented from blowing toward the user by making the wind shielding device shield the air outlet. Namely, the wind shielding device provided by the invention has the advantages that the dustproof function is added, and the cost performance of the wind shielding device is improved.
For example, as shown in fig. 5, during the operation of the air conditioner, it is determined whether the air conditioner is performing the self-cleaning mode, and if the determination result is "yes", that is, the air conditioner is performing the self-cleaning mode, the wind shielding device is caused to shield the wind outlet.
It should be noted that, the term that the wind shielding device shields the wind outlet means that, if the wind shielding device does not shield the wind outlet at this time, the wind shielding device is opened to shield the wind outlet; if the wind shielding device is already at the position for shielding the air outlet, the wind shielding device is kept at the current state.
In addition, it should be noted that if the determination result is "no", that is, the air conditioner does not execute the self-cleaning mode, in this case, the wind shielding device may or may not shield the air outlet.
The control method of the present invention will be described in detail with reference to a specific embodiment.
As shown in fig. 6, the control method of the present invention includes the steps of:
s100: and judging whether the air conditioner executes a self-cleaning mode.
In the process of the air conditioner running, the air conditioner can automatically judge whether the self-cleaning mode is executed, for example, in the process of the air conditioner running, if a self-cleaning instruction is received or a setting condition for executing the self-cleaning mode is met, the air conditioner indicates that the air conditioner is about to execute the self-cleaning mode, in this case, the air conditioner is enabled to execute the step S200, and in the case that the self-cleaning instruction is not received or the setting condition for executing the self-cleaning mode is not met or the self-cleaning mode is executed completely, in this case, the step S300 is executed.
S200: so that the wind shielding device shields the wind outlet.
In the process of self-cleaning of the air conditioner, the wind shielding device shields the air outlet and blocks dust blown out from the air outlet.
S300: and acquiring the target temperature.
S400: and acquiring the indoor temperature.
Before or after the air conditioner performs the self-cleaning mode, that is, in a case where the air conditioner does not perform the self-cleaning mode, a target temperature and an indoor temperature are acquired, and then the wind shielding device is selectively caused to shield the wind outlet according to the indoor temperature and the target temperature.
For example, the indoor temperature may be directly compared with the target temperature, and when the indoor temperature reaches or approaches the target temperature, the wind shielding device is further caused to shield the air outlet, otherwise, the wind shielding device is not caused to shield the air outlet; or, the difference between the indoor temperature and the target temperature may be calculated first, and then whether the wind shielding device shields the wind outlet may be determined according to the difference.
Compare in making always to hide the wind device and shelter from the air outlet, selectively make according to indoor temperature and target temperature and hide the wind device and shelter from the air outlet for the air conditioner is more intelligent, and, when indoor temperature differed greatly with the target temperature, is favorable to improving the efficiency that the air conditioner refrigerates or heats, promotes user's use and experiences.
Preferably, as shown in fig. 6, "selectively making the wind shielding device block the wind outlet according to the indoor temperature and the target temperature" specifically includes the following steps:
s500: the difference between the indoor temperature and the target temperature is calculated.
S600: and judging whether the difference value is smaller than a first preset value or not.
After the target temperature and the indoor temperature are obtained, the difference value between the target temperature and the indoor temperature is calculated, then the difference value is compared with a first preset value, and the wind shielding device is selectively enabled to shield the wind outlet according to the comparison result.
It should be noted that, in the cooling mode of the air conditioner, the difference between the indoor temperature and the target temperature is equal to the indoor temperature — the target temperature; in the air conditioner performing the heating mode, a difference between the indoor temperature and the target temperature is equal to the target temperature — the indoor temperature.
Specifically, as shown in fig. 6, when it is determined that the difference is smaller than the first preset value, step S200 is executed, even if the wind shielding device shields the wind outlet; when it is determined that the difference is not less than the first preset value, step S700 is performed, i.e., the wind shielding device is not shielded from the wind outlet.
Taking the air conditioner to execute the cooling mode as an example, the first preset value is 5, and when the difference is greater than or equal to 5, the difference between the indoor temperature and the target temperature is large, so that the air shielding device does not shield the air outlet, the indoor temperature is reduced as soon as possible, and the cooling efficiency is improved; when the difference is less than 5, the difference between the indoor temperature and the target temperature is small, so that the wind shielding device shields the air outlet to prevent cold wind discharged from the air outlet from directly blowing to a user.
It should be noted that the specific value of the first preset value is not limited to 5, for example, it can also be 3 or 6, etc., and such adjustment and change of the specific value of the first preset value without departing from the principle and scope of the present invention should be limited within the protection scope of the present invention.
Preferably, the step of "making the wind shielding device shield the wind outlet" specifically includes: when the difference value is larger than the second preset value and smaller than the first preset value, the wind shielding device is enabled to discontinuously shield the wind outlet; if the wind shielding device is smaller than or equal to the second preset value, the wind shielding device continuously shields the air outlet. And the second preset value is smaller than the first preset value.
That is, the wind shield apparatus of the present invention has two modes of operation: standard mode and gust mode. When the wind shielding device operates in the standard mode, the wind shielding device continuously shields the wind outlet; when the wind shielding device operates in a gust mode, the wind shielding device discontinuously shields the air outlet.
When the difference between the indoor temperature and the target temperature is less than a first preset value, the wind shielding device needs to shield the air outlet, then the difference is compared with a second preset value, the wind shielding device is selectively operated in a standard mode or a gust mode according to the comparison result, specifically, if the difference is greater than the second preset value, the wind shielding device is operated in the gust mode, namely, the wind shielding device intermittently shields the air outlet; and if the difference value is less than or equal to the second preset value, enabling the wind shielding device to operate in a standard mode, namely enabling the wind shielding device to continuously shield the air outlet.
It should be noted that, during the self-cleaning mode of the air conditioner, the wind shielding device is operated in the standard mode.
