specific Embodiment 1

[0032] This embodiment proposes a method for controlling the air deflector of the air conditioner, such as figure 1 As shown, the control method of this embodiment includes the following steps:

[0033] In step S1, when the air conditioner is running normally, the running current of the motor driving the wind deflector is detected in real time.

[0034] In this embodiment, when the air conditioner is powered on and running, the drive motor drives the wind deflector to rotate, and the resistance to the rotation of the wind deflector is its load. If the resistance is large, the load will be large, and if the resistance is small, the load will be small, and the load is directly proportional to its current. . When the wind deflector rotates normally, the speed is constant and the resistance is constant. When the wind deflector is subjected to external force, the resistance increases. When the external force on the wind deflector reaches a certain value, its current will correspo...

specific Embodiment 2

[0047] The difference between the control method of the air-conditioning deflector of this embodiment and Embodiment 1 is that this embodiment does not need to store the preset current I in the memory of the air conditioner in advance. Drive the opening of the wind deflector to reach the maximum position, at this time, detect the running current of the driving motor as the preset current I.

[0048] Specifically, such as image 3 As shown, the control method of this embodiment includes the following steps:

[0049] Step S1, when the air conditioner is powered on, control the driving motor of the air deflector to drive the opening of the air deflector to the maximum position, that is, the reference position, detect the operating current of the driving motor of the air deflector at this time, and use this operating current as the preset current I , to store in the air conditioner memory.

[0050] S2. The air conditioner is running normally, and the running current of the driving...

specific Embodiment 3

[0064] The difference between the control method of the air-conditioning air deflector in this embodiment and Embodiment 2 is that the rotation speed of the air-conditioning air deflector in this embodiment is related to the wind speed gear, and the rotational speed of the air deflector driving motor increases with the decrease of the wind speed gear. decrease. When the fan gear of the air conditioner in this embodiment is higher, the noise generated by the fan and the airflow will cover up the noise generated by the rotation of the driving motor. Therefore, the noise generated by the rotation of the drive motor is also greatly reduced, the overall noise of the air conditioner is reduced, and zero noise can be achieved in silent mode and sleep mode. In this embodiment, when the air conditioner is powered on, the wind speed gear of the air conditioner is first judged, and the operating current when the wind deflector driving motor drives the wind deflector to the maximum positi...

Abstract

The invention relates to a method and a device for controlling an air conditioning air deflector. The method comprises: detecting operating current of an air deflector driving motor when an air conditioning operates, comparing the operating current with preset current, when the operating current is larger than or equal to the preset current, indicating that external forces are applied on the air deflector in an operating process of the air deflector, the air deflector may impact with an air conditioning framework or the air deflector being pulled artificially, then, controlling the driving motor to stop rotation or driving the air deflector to reset, to reduce noise generated by impact and friction, and the driving motor being not damaged, when the air deflector has external forces, if a shut-off signal exists, indicating that the air deflector reaches an air deflector close position, controlling the driving motor to stop rotation, if no shut-off signal exists, controlling the air deflector to automatically reset for one time, powering on again being not needed, to improve comfortableness and intelligence of the air conditioning.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a control method and device for an air conditioner air deflector. Background technique [0002] At present, air conditioners have widely entered people's daily life and become a necessity of life. In order to accurately find the reference position and closing position of the existing air conditioner, the traditional control method of the air deflector of the air conditioner is the step control of the air deflector, so as to meet the precise control of the number of steps of the air deflector and the normal closing effect. However, the overstep The control has the following disadvantages: the air conditioner will use overstep control when finding the reference position and the closed position of the air deflector. On the one hand, it will cause the air deflector to collide with the frame of the air conditioner, resulting in annoying noise for users, which cann...
