CN-116221959-B - Control method for air conditioner and air conditioner
Abstract
The invention relates to the technical field of air conditioners, in particular to a control method for an air conditioner and the air conditioner, and aims to solve the problem that the normal operation of the air conditioner is affected due to shutdown protection when the conventional air conditioner enters forced defrosting in a heating mode, so that the use experience of a user is poor. The air conditioner has a forced defrosting mode, when the continuous operation time of the air conditioner in the heating mode exceeds the preset time in the heating mode, the air conditioner enters the forced defrosting mode, and before the air conditioner executes the forced defrosting mode, the control method comprises the steps of obtaining the target temperature Ta set by a user of the air conditioner in the heating mode, and selectively enabling the air conditioner to execute the forced defrosting mode according to the target temperature Ta. According to the invention, the target temperature can be obtained, and the forced defrosting mode of the air conditioner can be selectively executed according to the target temperature, so that the air conditioner is prevented from stopping running due to overcurrent shutdown protection, and the use experience of a user is improved.

Description
Control method for air conditioner and air conditioner Technical Field The invention relates to the technical field of air conditioners, and particularly provides a control method for an air conditioner and the air conditioner. Background At present, air conditioners in the market generally have a forced defrosting mode, and when the operation time of the air conditioner in a heating mode reaches a preset time, a forced defrosting mechanism is triggered to enable the air conditioner to enter the forced defrosting mode. The existing air conditioner directly enables the air conditioner to execute the forced defrosting mode after the forced defrosting mechanism is triggered, but when the air conditioner operates under some special working conditions, such as the inner machine and the outer machine of the air conditioner are operated under the working conditions of high power and high load pressure, the air conditioner is easy to generate overcurrent shutdown protection, namely the total current of the air conditioner exceeds the set current to cause the shutdown of the air conditioner, and the use experience of a user is affected. It has been found through experiments that, in the case where the air conditioner is operated in the heating mode, when the heating target temperature set by the user exceeds the first preset temperature (for example, 20 ℃) and the outdoor ambient temperature exceeds the second preset temperature (for example, 15 ℃), overcurrent shutdown protection is liable to occur. In the prior art, when the operation time of the air conditioner in the heating mode reaches the preset time, a forced defrosting mechanism is triggered and the air conditioner is directly enabled to execute the forced defrosting mode, so that the problem that the use experience of a user is affected due to the fact that the air conditioner is protected by overcurrent shutdown is caused. Accordingly, there is a need in the art for a new solution to the above-mentioned problems. Disclosure of Invention The invention aims to solve the technical problems at least to a certain extent, namely, the problem that the normal operation of the air conditioner is affected due to the existence of overcurrent shutdown protection when the forced defrosting is executed in a heating mode of the existing air conditioner, so that the use experience of a user is poor is solved at least to a certain extent. In a first aspect, the invention provides a control method for an air conditioner, the air conditioner is provided with a forced defrosting mode, when the air conditioner is in a heating mode and the continuous operation time of the air conditioner in the heating mode exceeds a preset time, the air conditioner enters the forced defrosting mode, and before the air conditioner executes the forced defrosting mode, the control method comprises the steps of acquiring a target temperature Ta set by a user of the air conditioner in the heating mode, and selectively enabling the air conditioner to execute the forced defrosting mode according to the target temperature Ta. In the above preferred technical solution of the control method for an air conditioner, the step of selectively enabling the air conditioner to perform the forced defrosting mode according to the target temperature Ta specifically includes comparing the target temperature Ta with the first preset temperature T1, and selectively enabling the air conditioner to perform the forced defrosting mode according to a comparison result. In the above preferred technical solution of the control method for an air conditioner, the step of selectively causing the air conditioner to perform the forced defrosting mode according to the comparison result specifically includes causing the air conditioner to perform the forced defrosting mode if the target temperature Ta is less than the first preset temperature T1. In the above preferred technical solution of the control method for an air conditioner, the step of selectively enabling the air conditioner to execute the forced defrosting mode according to the comparison result specifically includes further acquiring an outdoor environment temperature Tb of an outdoor unit of the air conditioner if the target temperature Ta is greater than or equal to the first preset temperature T1, comparing the outdoor environment temperature Tb with a second preset temperature T2, and selectively enabling the air conditioner to execute the forced defrosting mode according to the comparison result. In the above preferred technical solution of the control method for an air conditioner, the step of selectively enabling the air conditioner to perform the forced defrosting mode according to the comparison result specifically includes obtaining a total current value I0 of the air conditioner at intervals of set time if the outdoor ambient temperature Tb is greater than or equal to the second preset temperature T2, comparing the total current value I0 with a first preset
