Figure 15As shown, when the first guard net assembly 21 and the second guard net assembly 22 are in a separated state (when assembling the air conditioner), the c surface of the opening groove in the brush 25 is parallel to the d surface of the fixed hanger 27. Since the width a of the fixed hanger is set to be less than the width b of the opening groove, the brush 25 can be sequentially inserted into the connecting piece 26 at the bottom of the guard net assembly, that is, Figure 14 As shown; through the fixed hanger and the connecting structure provided at both ends of the connecting member 26, the fixed hanger 27 is screwed downward clockwise, and finally the depth of engagement in the threaded hole is determined according to the different softness of the selected brush, and the c surface of the opening groove 251 is kept perpendicular to the d surface of the fixed hanger 27.

[0078] Preferably, in combination with the above scheme, Figure 19 As shown, the detection module is also configured to detect whether there are foreign objects in the air duct of the indoor unit of the air conditioner; the control module is also configured to control the driving mechanism to drive the guard net assembly to slide back and forth in the air duct according to the judgment result of the judgment module, and clean the air duct through the brush 25 on the guard net assembly 2; adopting the above scheme, the cleaning device (i.e., the brush) on the guard net assembly cleans the air duct by raising and lowering the guard net assembly, without the need to set up an additional cleaning assembly.

[0079] Accordingly, combined with the above scheme, if Figure 20 As shown, the present invention also provides a control method for an air conditioner indoor unit, which is applied to the control system described above; specifically, the control method includes the following processes:

[0080] S1: When the air conditioner starts running, the detection module preferably detects the normal light intensity in the room. 室内 , and record and store;

[0081] S2: The transmitting module starts to transmit light signals to the receiving module;

[0082] S3: The receiving module collects the light signal I emitted by the transmitting module at intervals of Δt n ;

[0083] S4: Judgment module passes comparison I 室内 and I n To determine whether there is a person or a foreign object;

[0084] S5: When I n <I 室内 When the judgment module determines that there is a person or foreign object, the control module controls the guard net component 2 to be located at the air outlet 11;

[0085] S6: When I n ≥I 室内 When the air conditioner is in the air, the judgment module determines that there is no person or foreign object, and the control module controls the guard net component to be hidden in the air duct.

[0086] Preferably, in combination with the above scheme, Figure 20 As shown, and reference Figures 16 to 18 , step S5 specifically also includes:

[0087] S51: When the judgment module determines that there is a person or a foreign object;

[0088] S52: The judgment module judges the position of the guard net component 2;

[0089] S53: When the guard net assembly 2 is located at the preset position of the air outlet 11, the guard net assembly 2 remains stationary, and the control module controls the buzzer to sound an alarm;

[0090] S54: When the guard net assembly 2 is not located at the preset position of the air outlet 11, the control module controls the driving mechanism to drive the guard net assembly 2 to slide to the preset position of the air outlet 11, and the control module controls the buzzer to alarm.

[0091] Preferably, in combination with the above scheme, Figure 19 As shown, and reference Figures 16 to 18 Specifically, step S6 further includes:

[0092] S61: When the judgment module determines that there is no person or foreign object;

[0093] S62: The judgment module judges the position of the guard net component 2;

[0094] S63: When the guard net assembly 2 is located at a preset position in the air duct, the guard net assembly 2 remains stationary;

[0095] S64: When the guard net assembly 2 is not located at the preset position in the air duct, the control module controls the driving mechanism to drive the guard net assembly 2 to slide to the preset position in the air duct.

[0096] Specifically, using the above solution, when the air conditioner is initially powered on, the state of the screen protection component needs to be controlled by the signal fed back by the photoelectric detection; when it is turned on for the first time, the transmitting module first transmits light under normal indoor lighting conditions (without any obstructions), and the receiving module at the other end of the air conditioner receives the light from the transmitting end and the indoor ambient light, and records and stores the current state. 室内 , as a reference value for subsequent logical judgment; further, according to the actual indoor situation, the receiving module records and stores n groups of data (I1, I2, ... I n ), preferably five groups, are compared with the initial illumination data, and Δt is set to 1s; when I n <I 室内 , it is judged that the air outlet is blocked by people / foreign objects at this time, and the position state P of the guard net component at this moment is further judged. If P=0 (that is, the guard net component is at the bottom end of the arc track groove in the bottom shell structure), the motor starts to run, driving the guard net component to rise and block the air outlet, and the buzzer sounds at a high pitch to warn people to avoid reaching out and touching the transmission components inside the air duct and causing injuries; if P=1 (that is, the guard net component is at the top end of the arc track groove in the bottom shell structure), the guard net component maintains this state, and the buzzer sounds at a high pitch; when I is not satisfied n ≥I 室内 , judge whether the air outlet is blocked by people or foreign objects at this time, and judge the position state P of the guard net component at this moment. If P = 0, the guard net component maintains this state; if P = 1, the motor starts to reverse, driving the guard net component to descend to be completely hidden in the air duct, exposing the air outlet; the running track of the guard net component in the arc track groove is as follows Figures 16 to 18 Furthermore, in order to avoid the influence of light intensity at different times of the day, it is set to re-detect and record the I under unobstructed conditions every 1 hour. 室内 , update the data; when the air conditioner receives a shutdown command, the air guide plate is closed, if P = 1 at this time, the motor starts to reverse, driving the guard net component to drop into the air duct completely hidden in the bottom shell structure, exposing the air outlet; when the air conditioner is initially powered off and shut down, the guard net component state P should be 0 at this time, and the air outlet is completely exposed. At this time, it can be cleaned according to user needs.

[0097] Furthermore, for cleaning inside the air duct, photoelectric detection can be used to detect whether there are foreign objects at the air outlet, and the forward / reverse rotation of the motor can be controlled by logic to drive the guard net assembly to rise / fall, so that the cleaning device on the guard net assembly can follow the sliding along the arc track groove on the bottom shell to sweep the air duct; in addition, in order to improve the timeliness of cleaning the dust in the air duct, a separate logic control of the air duct cleaning instruction can be provided to provide photoelectric detection, and the method involving the detection of dust concentration in the air duct is already very mature, so I will not go into details here.

[0098] The solution provided by the present invention can protect the air outlet of the indoor unit of the air conditioner and is convenient for disassembly and assembly; by controlling the movement of the protective net assembly, it can solve the problems of uneven air outlet and frequent noise, and at the same time solve the problem of air duct cleaning, thereby improving the experience of the air conditioner.

[0099] It is further understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.
