Description

Air conditioner, control method and device thereof, storage medium and product Technical Field The present application relates to the field of air conditioners, and in particular, to an air conditioner, a control method, an apparatus, a storage medium, and a product thereof. Background When the air conditioner operates in the heating mode, because the initial heating capacity is weak at the start-up, if the indoor fan of the air conditioner operates in a wind gear set by a user, the temperature of the indoor heat exchanger can be quickly reduced to be lower than the indoor environment temperature, so that the air conditioner blows cold air indoors. In order to prevent cold air from being blown into the room when the temperature of the indoor heat exchanger is low, the air conditioner generally has a cold air prevention function, when the air conditioner enters a heating mode to operate, the air baffle is adjusted based on the temperature of the indoor heat exchanger, when the temperature of the indoor heat exchanger is low, the air conditioner operates in a light air baffle or stops blowing in order to prevent the temperature of the indoor heat exchanger from rapidly falling below the indoor environment temperature, when the temperature of the indoor heat exchanger is high, the air conditioner operates in a set air baffle, and when the heating capacity of the air conditioner meets the mode requirement, the air conditioner resumes a normal heating mode to set the air baffle to continue to operate. In the related art, the air conditioner enters the initial stage of starting the heating mode, and the relationship between the air shield of the air conditioner and the temperature of the indoor heat exchanger is shown in fig. 1. It should be noted that, the cold air prevention function of the air conditioner is triggered after receiving the heating mode instruction of the user, and for the air conditioner with heating Bao Shuangsu melting function, the cold air prevention function is still triggered after the air conditioner exits from the defrosting mode. Here, when the air conditioner is operated in the defrost mode, the air conditioner shunts a portion of heat of the indoor unit to the outdoor unit to remove the frost covering the outdoor unit by controlling the opening degree of the expansion valve and reducing the wind speed of the indoor unit. However, when the air conditioner is operated in the defrosting mode, the temperature of the indoor heat exchanger is rapidly increased due to the low wind speed of the indoor unit, and when the air conditioner exits from the defrosting mode and is switched to the heating mode, according to the air shift control method shown in fig. 1, the air conditioner may be switched to the set air shift operation due to the excessively high temperature of the indoor heat exchanger, and at this time, the actual heating amount of the air conditioner is not matched with the wind speed in the process of exiting from the defrosting mode by the compressor and the expansion valve, and the temperature of the indoor heat exchanger is rapidly reduced, so that the condition of blowing cold air into the room occurs. Disclosure of Invention In view of this, the embodiments of the present application provide an air conditioner, a control method, an apparatus, a storage medium, and a product thereof, which aim to solve the problem of blowing cold air into a room when the air conditioner is switched from a defrosting mode to a heating mode.

In some embodiments, the method further comprises: responding to a heating mode instruction sent by a user, controlling the air conditioner to enter the heating mode to operate, and And controlling the air conditioner to enter the heating mode operation based on the operation of exiting the defrosting mode. In some embodiments, the method further comprises: In the defrosting mode, controlling the
