Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As used in this specification of the present invention and the appended claims, unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0038] It should be further understood that the term "and / or" used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0039] As used in this specification and the appended claims, the term "if" can be interpreted, depending on the context, as "when", "once", "in response to determining", or "in response to detecting". Similarly, the phrases "if determined" or "if [the described condition or event] is detected" can be interpreted, depending on the context, as meaning "once determined", "in response to determining", "once [the described condition or event] is detected", or "in response to detecting [the described condition or event]".

[0040] Please refer to Figures 1 to 9 , the air conditioner drain unclogging device includes a bottom case 10 and an unclogging component 20. Among them, a driving member 11 and a detecting member 12 are installed on the bottom case 10, a drain port is provided on the bottom case 10, and the detecting member 12 is used to detect whether the drain port is blocked; the unclogging component 20 includes an unclogging member 21 and a guide rail 22 provided on the bottom case 10. Both ends of the guide rail 22 are arranged corresponding to the drain port, and the unclogging member 21 is arranged in the guide rail 22; among them, when the detecting member 12 detects that the drain port is blocked, the driving member 11 drives the unclogging member 21 to move along the guide rail 22 to unclog the drain port. It should be noted that in this embodiment, the detecting member 12 is a water level sensor, and the water level in the drain pipe of the air conditioner is detected by the water level sensor to determine whether the drain port is blocked. When the water level in the drain pipe is relatively high, it is determined that the drain port is blocked, and vice versa, it is determined that the drain port is not blocked; when the drain port is blocked, the driving member 11 drives the unclogging member 21 to move along the guide rail 22 to unclog the drain port, effectively avoiding the blockage of the drain port and the water leakage of the air conditioner caused by the blockage, and improving the user experience.

[0041] Please refer toFigures 1 to 5 , the dredging member 21 is strip-shaped and includes a toothed section 211 and dredging sections 212 provided at both ends of the toothed section 211. The dredging sections 212 are used to dredge the drain opening. Understandably, the dredging sections 212 are arranged corresponding to the drain opening. Specifically, the driving member 11 is a motor, the motor includes a bearing, and a driving gear is formed on the bearing. A toothed structure 2111 adapted to the driving gear is provided on the toothed section 211. Through the driving gear and the toothed structure 2111, the motor can drive the dredging member 21 to move along the guide rail 22. More specifically, a groove 2112 is further provided on the toothed section 211, and a protruding portion 221 is provided in a region of the guide rail 22 corresponding to the toothed section 211. The groove 2112 is engaged with the protruding portion 221 so that the dredging member 21 is installed in the guide rail 22. It should be noted that in this embodiment, the dredging member 21 is a soft dredging member 21, and the dredging section 212 is formed by bending the end of the toothed section 211 to adapt to the shape of the guide rail 22. It should also be noted that as Figure 6 shown, the cross-section of the guide rail 22 is in the shape of a "mountain".

[0042] Please continue to refer to Figures 7 to 9 , the dredging assembly 20 further includes a guide rail cover 23 covering the guide rail 22. A receiving area is formed on the guide rail cover 23, and the dredging member 21 is received in the receiving area to limit the movement of the dredging member 21 in the up and down direction. Specifically, guide members 231 are provided at both ends of the guide rail cover 23. As Figure 8 shown, a guiding and dredging portion 2311 is provided on the guide member 231. The guiding and dredging portion 2311 is arranged facing the drain opening and is used to guide the dredging member 21. More specifically, a protruding structure 232 is formed on the guide rail cover 23. The protruding structure 232 is used to cover and install the driving member 11 on the bottom case 10. The driving member 11 is a motor. In this application, after the guide rail cover 23 covers the guide rail 22, the protruding structure 232 can prevent the motor from being exposed.

[0043] Please continue to refer to Figures 1 to 3, a left drain port and a right drain port are provided on the bottom case 10, the guide rail 22 is provided between the left drain port and the right drain port, and the detection member 12 is provided above both the left drain port and the right drain port. It should be noted that, in this embodiment, the detection member 12 is a water level sensor. By installing the water level sensor above the left drain port and the right drain port, the water level in the drain pipe of the air conditioner can be accurately detected, and then it can be determined whether the drain port is blocked. Understandably, when the drain port is blocked by a mixture of fluff and dust, etc., the water in the drain pipe cannot be smoothly discharged, the water level rises, and when the water level rises to a certain height, the water level sensor is triggered. The water level sensor sends a dredging trigger signal to the main board in the air conditioner. After the main board receives the trigger dredging signal sent by the water level sensor, the relay on the main board supplies power to the motor, driving the motor to drive the dredging member 21 to move, achieving the effect of dredging the drain port.

[0044] In this embodiment, an air conditioner is further provided. The air conditioner includes a drain pipe and the above-mentioned air conditioner drain port dredging device. When the drain port is blocked and the water level in the drain pipe rises, the drain port can be dredged through the air conditioner drain port dredging device, effectively avoiding the blockage of the drain port and the water leakage problem of the air conditioner caused by the blockage. It not only improves the user experience but also improves the intelligent level of the air conditioner.

[0045] Please refer to Figure 10 , Figure 10 is a schematic flowchart of the air conditioner drain port dredging method provided by the embodiment of the present invention. The air conditioner drain port dredging method will be described in detail below. As Figure 10 shown, the method includes the following steps S110 - S120.

[0046] S110. Detect whether the obtained water level value meets the dredging trigger condition;

[0047] S120. If the dredging trigger condition is met, control the motor to drive the dredging strip to move towards the drain port to dredge the drain port.

[0048] In this embodiment, when the air conditioner is turned on for refrigeration operation, the water level sensor detects the water level in the drain pipe to obtain a water level value, and determines whether the dredging trigger condition is met according to the water level value. Specifically, determining whether the dredging trigger condition is met according to the water level value means determining whether the water level value is greater than a preset water level value; if the water level value is greater than the preset water level value, it is determined that the dredging trigger condition is met, and the motor is controlled to drive the dredging strip to move towards the drain outlet to dredge the drain outlet; on the contrary, if the water level value is not greater than the preset water level value, it is determined that the dredging trigger condition is not met; when the dredging trigger condition is not met, the air conditioner operates normally and does not enter the dredging process, that is, the drain outlet is not dredged.

[0049] In some embodiments, such as this embodiment, as Figure 11 shown, step S120 may include steps S121-S124.

[0050] S121. If it is the first time to meet the dredging trigger condition, control the motor to start, and control the motor to drive the dredging member to move in the first direction, and use the maximum driving current during the movement process as the first driving current;

[0051] S122. After a preset movement time, control the motor to drive the dredging member to move in the second direction, and use the maximum driving current during the movement process as the second driving current;

[0052] S123. Determine the target movement direction according to the first driving current and the second driving current;

[0053] S124. If it is not the first time to meet the dredging trigger condition, control the motor to drive the dredging strip to move in the target movement direction to dredge the drain outlet.

[0054] In this embodiment, if it is the first time to meet the dredging trigger condition, control the motor to start, and control the motor to drive the dredging member to move in the first direction, and use the maximum driving current during the movement process as the first driving current, where the first direction is the direction towards the left drain outlet; after a preset movement time, control the motor to drive the dredging member to move in the second direction, and use the maximum driving current during the movement process as the second driving current, where the second direction is the direction opposite to the first direction, that is, the second direction is the direction towards the right drain outlet; determine the target movement direction according to the first driving current and the second driving current; if it is not the first time to meet the dredging trigger condition, control the motor to drive the dredging strip to move in the target movement direction to dredge the drain outlet. It should be noted that the preset movement time is T1 s, and T1 is set according to actual needs; the driving current is the driving current when the motor drives the dredging member to move.

[0055] Further, if the user manually enters the dredging process using the remote control, that is, if the air conditioner receives a manual dredging instruction, it will execute the step of controlling the motor to drive the dredging strip to move in the target movement direction to dredge the drain outlet. Understandably, after receiving the manual dredging instruction, even if the dredging trigger condition is not met, the drain outlet will be dredged.

[0056] In some embodiments, such as this embodiment, as Figure 12 shown, the step S123 may include steps S1231 - S1233.

[0057] S1231. If the first driving current is equal to the second driving current, return to execute the step of controlling the motor to drive the dredging member to move in the first direction, and use the maximum driving current during the movement as the first driving current;

[0058] S1232. If the first driving current is greater than the second driving current, then use the second direction as the target movement direction;

[0059] S1233. If the first driving current is less than the second driving current, then use the first direction as the target movement direction.

[0060] In this embodiment, for ease of description, the first driving current is denoted as A1, and the second driving current is denoted as A2. Judge the magnitudes of A1 and A2. If A1 > A2, it means that the left drain outlet is not connected to the drain pipe, and the air conditioner uses the right drain outlet for drainage. Then use the second direction as the target movement direction. And when the dredging trigger condition is subsequently met, the main board directly sends a right - movement signal to the motor, so that the motor drives the dredging member to move in the direction of the right drain outlet; if A1 = A2, return to execute the step of controlling the motor to drive the dredging member to move in the first direction, and use the maximum driving current during the movement as the first driving current, and re - obtain A1 and A2 for comparison; if A1 < A2, it means that the right drain outlet is not connected to the drain pipe, and the air conditioner uses the left drain outlet for drainage. Then use the first direction as the target movement direction. And when the dredging trigger condition is subsequently met, the main board directly sends a left - movement signal to the motor, so that the motor drives the dredging member to move in the direction of the left drain outlet.

[0061] Refer to Figure 13 , Figure 13A flowchart of a method for dredging the drain outlet of an air conditioner provided in another embodiment of the present invention. After the air conditioner drain outlet dredging device is installed, the air conditioner is turned on for refrigeration, and the water level sensor detects whether the dredging trigger condition is met according to the obtained water level value; if the dredging trigger condition is not met, the air conditioner operates normally; if the dredging trigger condition is met and it is the first time, the motor is controlled to start and drive the dredging member to move to the left, that is, in the first direction, and the maximum driving current A1 during the movement process is recorded; after the motor drives the dredging member to move to the left for T1 time, the motor drives the dredging member to move to the right, that is, in the second direction, and the maximum driving current A2 during the movement process is recorded; compare the magnitudes of A1 and A2; if A1 > A2, then the second direction is taken as the target movement direction, that is, the right movement direction is taken as the target movement direction; if A1 = A2, then return to execute the step of driving the dredging member to move to the left, that is, in the first direction, and record the maximum driving current A1 during the movement process, and re-obtain A1 and A2 for comparison; if A1 < A2, then the first direction is taken as the target movement direction, that is, the left movement direction is taken as the target movement direction; if the dredging trigger condition is met and it is not the first time, the motor is controlled to drive the dredging member to move in the saved target movement direction to dredge the drain outlet; if a manual dredging instruction is received, then execute the step of controlling the motor to drive the dredging bar to move in the target movement direction to dredge the drain outlet. In practical applications, a manual entry interface is set on the remote control. If the user manually enters the dredging process using the remote control, the drain outlet will be dredged regardless of whether it is blocked. Understandably, through the above dredging process, the blockage of the air conditioner drain outlet can be dredged, the problem of water leakage due to blockage of the air conditioner is solved, the user experience and the intelligent level of the air conditioner are improved. Moreover, the service life of the air conditioner can be extended.
