[0046] The water receiving tray 10 is provided with a drainage hole 11; the drainage plug 20 cooperates with the drainage hole 11 and can move relative to the drainage hole 11 between a closed position for closing the drainage hole 11 and an open position for opening the drainage hole 11; the driving device 30 is drivingly connected to the drainage plug 20, and is used to drive the drainage plug 20 to move between the closed position and the open position.

[0047] like Figure 5 As shown, the drain plug 20 is in the closed position. Figure 7As shown, the drain plug 20 is in the open position.

[0048] By using the water receiving pan assembly for the air conditioner provided by the embodiment of the present disclosure, the driving device 30 can be provided to drive the drain plug 20 to move precisely between the closed position for closing the drain hole 11 and the open position for opening the drain hole 11 as required, so that the position of the drain plug 20 can be precisely controlled to avoid affecting the normal operation of the air conditioner due to excessive condensed water. The provision of the driving device 30 realizes the automatic control of the drainage process, avoids manual intervention, and can improve the drainage efficiency and accuracy.

[0049] The drive device 30 can reduce the difficulty of installing and removing the drain plug 20, avoiding the potential safety hazards of manual installation and removal. In addition, compared with the valve plate in the related art, the drain plug 20 has a better sealing effect when in the closed position, which can prevent condensed water from leaking from the water receiving pan 10.

[0050] Optionally, combined Figure 2 and Figure 4-8 As shown, the driving device 30 includes a driving member 31 , which is drivingly connected to the drain plug 20 and is used to drive the drain plug 20 to move axially along the drain hole 11 to open or close the drain hole 11 .

[0051] The driving member 31 provides power to drive the drain plug 20 to move axially along the drain hole 11, which can automatically open or close the drain hole 11 and accurately control the position of the drain plug 20 so that the drain hole 11 can be accurately opened or closed when needed, thereby improving the overall efficiency of the drainage operation.

[0052] Optionally, the driving member 31 is a linear motor.

[0053] The linear motor can directly convert electrical energy into linear motion mechanical energy, driving the drain plug 20 to move linearly along the axial direction of the drain hole 11, without the need to set additional transmission components between the linear motor and the drain plug 20. The linear motor can quickly respond to the adjustment requirements for the position of the drain plug 20, drive the drain plug 20 to move smoothly, and improve the stability and durability of the drive device 30. At the same time, the linear motor as the driving member 31 does not need to pass through the transmission components, and can also simplify the structure of the drive device 30 and save costs.

[0054] Optionally, combined Figure 4-8 As shown, the driving device 30 also includes a first transmission member 32 and a second transmission member 33. The first transmission member 32 is drivingly connected to the driving member 31; the second transmission member 33 is connected to the drain plug 20 and cooperates with the first transmission member 32; the driving member 31 drives the second transmission member 33 to move axially along the drain hole 11 through the first transmission member 32.

[0055] The first transmission member 32 is drivingly connected to the driving member 31, and the second rotating member cooperates with the first transmission member 32, so that the driving member 31 can drive the first transmission member 32 to drive the second transmission member 33 to move along the axial direction of the drain hole 11. The second transmission member 33 is connected to the drain plug 20, and the cooperation of the first transmission member 32 and the second transmission member 33 can transmit the power generated by the driving member 31 to the drain plug 20. The second transmission member 33 can drive the drain plug 20 to move along the axial direction of the drain hole 11, thereby opening or closing the drain hole 11.

[0056] Optionally, combined Figure 4-8 As shown, the first transmission member 32 includes a screw rod 321, which is drivingly connected to the driving member 31; the second transmission member 33 includes a nut 34, which is connected to the drain plug 20, and the screw rod 321 is threadedly connected to the nut 34 to drive the nut 34 to move axially along the drain hole 11.

[0057] The first transmission member 32 and the second transmission member 33 are threadedly connected to the nut 34 through the screw 321, the screw 321 is drivingly connected to the driving member 31, and the nut 34 is connected to the drain plug 20. The driving member 31 can be a rotary motor. Through the rotation principle of the thread, the driving member 31 drives the screw 321 to drive the nut 34 to move along the axial direction of the drain hole 11, thereby driving the drain plug 20 to move along the axial direction of the drain hole 11, and the drain hole 11 can be opened or closed.

[0058] The threaded connection can withstand a high load and can effectively drive the drain plug 20 to move between the open position and the closed position. The surface of the screw 321 can be a fine thread, which has more thread contact surfaces and can provide a tighter thread fit, thereby improving the fastening accuracy between the screw 321 and the nut 34.

[0059] The second transmission member 33 may be a nut bracket, which extends radially along the drain hole 11 , and the nut 34 is disposed in the middle of the nut bracket, and the nut bracket is connected to the drain plug 20 .

[0060] The nut bracket can provide a stable support to ensure that the nut 34 remains stable during movement and reduce tilting or deviation.

[0061] Optionally, combined Figure 4-8 As shown, the second transmission member 33 is provided with a guide portion 35 , and the water receiving tray 10 is provided with a first guide matching portion 12 . The guide portion 35 matches with the first guide matching portion 12 to enable the second transmission member 33 to move axially along the drainage hole 11 .

[0062] The guide portion 35 cooperates with the first guide matching portion 12 to guide the second transmission member 33 to move along the axial direction of the drain hole 11, which can drive the drain plug 20 to move along the axial direction of the drain hole 11, and at the same time limit the circumferential rotation of the second transmission member 33 along the drain hole 11. The guide portion 35 cooperates with the first guide matching portion 12 to guide the drain plug 20 to move precisely along the axial direction of the drain hole 11, reducing the deviation of the drain plug 20 during the movement. The second transmission member 33 moves toward the drain hole 11 along the axial direction of the drain hole 11, which can drive the drain plug 20 to move toward the closed position, thereby closing the drain hole 11. The second transmission member 33 moves away from the drain hole 11 along the axial direction of the drain hole 11, which can drive the drain plug 20 to move toward the open position, thereby opening the drain hole 11.

[0063] Optionally, combined Figure 4-8 As shown, the first guide matching portion 12 is disposed on the inner wall surface of the drainage hole 11 .

[0064] The first guide fitting portion 12 is disposed on the inner wall surface of the drain hole 11 , and can provide precise guidance for the second transmission member 33 so that the second transmission member 33 moves correctly along the axial direction of the drain hole 11 , thereby preventing the drain plug 20 from deflecting or tilting.

[0065] Optionally, one of the guide portion 35 and the first guide matching portion 12 is a slider 351, and the other is a first guide groove 121. The first guide groove 121 extends axially along the drainage hole 11, and the slider 351 moves along the first wire groove to make the second transmission member 33 move axially along the drainage hole 11.

[0066] The guide portion 35 may be a slider 351, and the first guide matching portion 12 may be a first guide groove 121. The guide portion 35 may be a first guide groove 121, and the first guide matching portion 12 may be a slider 351. Figure 4-8 As shown, the present application takes the guide portion 35 as a slider 351 and the first guide matching portion 12 as the first guide groove 121 as an example. The slider 351 slides in the first guide groove 121, which can provide precise guidance, so that the slider 351 moves smoothly along the axial path of the drainage hole 11 set by the first guide groove 121.

[0067] Optionally, combined Figure 4-8 As shown, there are multiple guide portions 35, and there are multiple first guide matching portions 12, and the multiple guide portions 35 correspond to the multiple first guide matching portions 12 one by one; the multiple guide portions 35 are relatively arranged at the two ends of the second transmission member 33 along the radial direction of the drainage hole 11; and the multiple first guide matching portions 12 are relatively arranged on the inner wall surface of the drainage hole 11 along the radial direction of the drainage hole 11.

[0068] The plurality of guide portions 35 and the plurality of first guide matching portions 12 are arranged correspondingly along the radial direction of the drainage hole 11 , which can increase the stability of the axial movement of the second transmission member 33 along the drainage hole 11 and improve the assembly accuracy between the drainage plug 20 and the drainage hole 11 .

[0069] Optionally, combined Figure 4 As shown, the second transmission member 33 is provided with a positioning portion 36 , and the drain plug 20 is provided with a positioning matching portion 21 . The positioning portion 36 matches with the positioning matching portion 21 to position the second transmission member 33 on the drain plug 20 .

[0070] Through the cooperation between the positioning portion 36 and the positioning matching portion 21, the second transmission member 33 can be stably positioned on the drain plug 20, preventing relative movement or displacement between the second transmission member 33 and the drain plug 20, so that the second transmission member 33 can drive the drain plug 20 to move stably.

[0071] Optionally, one of the positioning portion 36 and the positioning matching portion 21 includes a positioning rib 361 , and the other includes a positioning groove 211 , and the positioning rib 361 is snapped into the positioning groove 211 , so that the second transmission member 33 is limited to the drain plug 20 .

[0072] The positioning portion 36 may be a positioning rib 361, and the positioning matching portion 21 may be a positioning groove 211. The positioning portion 36 may be a positioning groove 211, and the positioning matching portion 21 may be a positioning rib 361. Figure 4 As shown, the present application takes the positioning portion 36 as the positioning rib 361 and the positioning matching portion 21 as the positioning groove 211 as an example. The second transmission member 33 is provided with the positioning rib 361, and the drain plug 20 is provided with the positioning groove 211. The positioning rib 361 is inserted into the positioning groove 211, so that the second transmission member 33 is firmly connected to the drain plug 20.

[0073] Optionally, one of the positioning portion 36 and the positioning matching portion 21 includes a buckle 362 , and the other includes a slot, and the buckle 362 is snapped into the slot, so that the second transmission member 33 is limited to the drain plug 20 .

[0074] Combination Figure 4-8 As shown, the present application takes the positioning portion 36 including the buckle 362 and the positioning matching portion 21 including the slot as an example. The buckle 362 is inserted into the slot to firmly fix the second transmission member 33, preventing the second transmission member 33 from being loosened from the drain plug 20 during operation. The buckle 362 can be connected to the positioning rib 361, so that the positioning rib 361 can serve as a supporting structure for the buckle 362, thereby improving the stability of the positioning portion 36.

[0075] Optionally, the water receiving tray 10 is provided with a first limiting portion, which is arranged corresponding to the first guide matching portion 12 to limit the movement range of the second transmission member 33 toward the closed position; and / or, the mounting bracket 37 is provided with a second limiting portion, which is arranged corresponding to the second guide matching portion 371 to limit the movement range of the second transmission member 33 toward the open position.

[0076] By providing the first limiting portion and the second limiting portion, the movement range of the second transmission member 33 relative to the water receiving tray 10 and the mounting bracket 37 is clearly defined, and excessive movement of the second transmission member 33 can be prevented.

[0077] When the first guide matching portion 12 is the first guide groove 121, the first limiting portion can be a first groove wall of the first guide groove 121 away from one end of the mounting bracket 37 along the axial direction of the drain hole 11. When the drain plug 20 is in the open position, the second transmission member 33 can abut against the mounting bracket 37, so that the inner wall of the mounting bracket 37 faces the second transmission member 33 to form a limit. When the second guide matching portion 371 is the second guide groove 372, the second limiting portion can be a second groove wall of the second guide groove 372 away from one end of the drain hole 11 along the axial direction of the drain hole 11.

[0078] Optionally, combined Figure 4-8 As shown, the screw rod 321 includes a first end and a second end axially oppositely arranged along the drain hole 11, the first end of the screw rod 321 is drivingly connected to the driving member 31, and the drain plug 20 is provided with a clearance groove 22, which is used to accommodate part or all of the second end of the screw rod 321 when the drain plug 20 moves; wherein, when the drain plug 20 is in the closed position, part or all of the second end of the screw rod 321 is located outside the clearance groove 22; when the drain plug 20 is in the open position, the second end of the screw rod 321 is located inside the clearance groove 22.

[0079] When the drain plug 20 moves toward the open position, the driving member 31 drives the screw rod 321 to rotate in the first direction, driving the nut 34 to move toward the first end of the screw rod 321. The nut 34 drives the drain plug 20 to move along the axial direction of the drain hole 11 toward the first end of the screw rod 321, so that the second end of the screw rod 321 is located inside the clearance groove 22. When the drain plug 20 is in the open position, the clearance groove 22 provides an escape space for the second end of the screw rod 321. The second end of the screw rod 321 is located inside the clearance groove 22, which can avoid the second end of the screw rod 321 from interfering with the drain plug 20, so that the screw rod 321 can smoothly drive the nut 34 and the drain plug 20 to move along the axial direction of the drain hole 11. It can be understood that when the driving member 31 is a rotary motor, the driving member 31 can drive the screw rod 321 to rotate in the positive direction, and the first direction is the positive direction.

[0080] When the drain plug 20 moves toward the open position, the rotation direction of the screw rod 321 is as follows: Figure 6shown.

[0081] When the drain plug 20 moves toward the closed position, the driving member 31 drives the screw rod 321 to rotate in the opposite direction of the first direction, driving the nut 34 to move away from the first end of the screw rod 321. The nut 34 drives the drain plug 20 to move away from the first end of the screw rod 321 along the axial direction of the drain hole 11, so that part or all of the second end of the screw rod 321 is located outside the clearance groove 22.

[0082] When the drain plug 20 moves toward the closed position, the rotation direction of the screw rod 321 is as follows: Figure 8 shown.

[0083] Optionally, combined Figure 2 and Figure 4-8 As shown, the driving device 30 also includes a mounting bracket 37, the mounting bracket 37 is arranged on the water receiving tray 10, and the driving member 31 is arranged on the mounting bracket 37; wherein, the second transmission member 33 is provided with a guide portion 35, and the mounting bracket 37 is provided with a second guide matching portion 371, and the guide portion 35 cooperates with the second guide matching portion 371 to enable the second transmission member 33 to move axially along the drainage hole 11.

[0084] The mounting bracket 37 is disposed on the water receiving tray 10 , and provides a stable base for the driving member 31 , thereby improving the stability and reliability of the driving member 31 .

[0085] The guide portion 35 cooperates with the second guide matching portion 371 to guide the second transmission member 33 to drive the drain plug 20 to move along the axial direction of the drain hole 11, while limiting the circumferential rotation of the second transmission member 33 along the drain hole 11. The guide portion 35 cooperates with the second guide matching portion 371 to guide the drain plug 20 to move precisely along the axial direction of the drain hole 11, thereby opening or closing the drain hole 11 and reducing the deviation of the drain plug 20 during movement.

[0086] Optionally, combined Figure 4-8 As shown, the guide portion 35 extends along the axial direction of the drain hole 11; the first guide matching portion 12 and the second guide matching portion 371 both extend along the axial direction of the drain hole 11, the first end of the guide portion 35 matches with the first guide matching portion 12, and the second end of the guide portion 35 matches with the second guide matching portion 371, so that the second transmission member 33 moves along the axial direction of the drain hole 11, driving the drain plug 20 to move between the open position and the closed position.

[0087] The matching design at both ends of the guide portion 35 provides double-end guidance, which increases the stability and accuracy of the guidance. Taking the embedded air conditioner as an example, the axial direction of the drain hole 11 is the up and down direction, the first end of the guide portion 35 is the lower end, and the second end of the guide portion 35 is the upper end. When the second transmission member 33 drives the drain plug 20 to move toward the closed position, the first end of the guide portion 35 moves downward along the first guide matching portion 12, and at the same time, the second end of the guide portion 35 moves downward along the second guide matching portion 371, so that the second transmission member 33 can move from the mounting bracket 37 toward the drain hole 11 along the axial direction of the drain hole 11, driving the drain plug 20 to close the drain hole 11. When the second transmission member 33 drives the drain plug 20 to move toward the open position, the first end of the guide portion 35 moves upward along the first guide matching portion 12, and at the same time, the second end of the guide portion 35 moves upward along the second guide matching portion 371, so that the second transmission member 33 can move from the drain hole 11 toward the mounting bracket 37 along the axial direction of the drain hole 11, driving the drain plug 20 to open the drain hole 11.

[0088] Optionally, combined Figure 2 and Figure 4 As shown, the water receiving tray 10 defines a water storage space, and the mounting bracket 37 is provided with a connecting hole 373 , which connects the water storage space with the drainage hole 11 .

[0089] The mounting bracket 37 is disposed on the water receiving tray 10, and the mounting bracket 37 is provided with a connecting hole 373 connecting the water storage space and the drainage hole 11, so that the water in the water storage space flows into the drainage hole 11 through the connecting hole 373, and can be drained more directly and quickly. It can be understood that the number of the connecting holes 373 can be multiple, and the provision of multiple connecting holes 373 can improve the drainage efficiency.

[0090] Optionally, a hydrophobic hole is provided on the outer wall surface of the drain plug 20 or the inner wall surface of the drain hole 11 to connect the connecting hole 373 with the external space.

[0091] The water in the water receiving tray 10 flows into the drain hole 11 through the connecting hole 373 on the mounting bracket 37 , then flows between the drain hole 11 and the drain plug 20 through the drainage hole, and finally flows out of the drain hole 11 .

[0092] Optionally, combined Figure 6 and Figure 8 As shown, the drain plug 20 is arranged in the drain hole 11, the drain plug 20 includes a first outer wall surface 24, and the drain hole 11 includes a first inner wall surface 112. The radial dimension of the first outer wall surface 24 is smaller than the radial dimension of the first inner wall surface 112, so that a drainage gap is left between the first outer wall surface 24 and the first inner wall surface 112.

[0093] The water in the water receiving tray 10 flows into the drain hole 11 through the connecting hole 373 on the mounting bracket 37 , then flows between the drain hole 11 and the drain plug 20 through the drainage gap, and finally flows out of the drain hole 11 .

[0094] Optionally, combined Figure 6 and Figure 8 As shown, the drain plug 20 is arranged in the drain hole 11, the inner wall surface of the drain hole 11 includes a first sealing surface 111, and the outer wall surface of the drain plug 20 includes a second sealing surface 23. When in the closed position, the first sealing surface 111 abuts against the second sealing surface 23; wherein, along the direction in which the drain plug 20 closes the drain hole 11, the first sealing surface 111 presents a closing structure, and the second sealing surface 23 matches the first sealing surface 111.

[0095] The direction in which the drain plug 20 closes the drain hole 11 is as follows: Figure 5 shown.

[0096] When in the closed position, the first sealing surface 111 abuts against the second sealing surface 23, which can form a tight seal between the outer wall of the drain plug 20 and the inner wall of the drain hole 11, so that the drain plug 20 closes the drain hole 11, thereby enhancing the sealing effect between the drain plug 20 and the drain hole 11.

[0097] The first sealing surface 111 is a closed structure, so that when the drain plug 20 is in the closed position, the first sealing surface 111 and the second sealing surface 23 are more closely abutted, which can effectively enhance the sealing between the drain plug 20 and the drain hole 11. At the same time, the first sealing surface 111 is a closed structure and can also play a guiding role, accurately guiding the drain plug 20 to move to the closed position along the closing direction, so that the first sealing surface 111 and the second sealing surface 23 are accurately aligned and abutted, thereby improving the sealing effect.

[0098] Optionally, along the direction in which the drain plug 20 opens the drain hole 11 , the first sealing surface 111 and the hydrophobic hole are arranged in sequence.

[0099] In the open position, the first sealing surface 111 is separated from the second sealing surface 23. Water in the water receiving tray 10 flows into the drain hole 11 through the connecting hole 373 on the mounting bracket 37, then flows between the drain hole 11 and the drain plug 20 through the drain hole, and finally flows out of the drain hole 11 through the separation gap between the first sealing surface 111 and the second sealing surface 23.

[0100] Optional, combined Figure 6 and Figure 8 As shown, along the direction in which the drain plug 20 opens the drain hole 11, the first sealing surface 111 and the drain gap are arranged in sequence.

[0101] In the open position, the first sealing surface 111 is separated from the second sealing surface 23. Water in the water receiving tray 10 flows into the drain hole 11 through the connecting hole 373 on the mounting bracket 37, then flows between the drain hole 11 and the drain plug 20 through the drainage gap, and finally flows out of the drain hole 11 through the separation gap between the first sealing surface 111 and the second sealing surface 23.

[0102] Optionally, combined Figure 2 and Figure 4 As shown, the mounting bracket 37 is provided with a first mounting hole 374 , the driving member 31 is provided with a first mounting matching hole 311 , and the water tray assembly further includes a first fastener, which cooperates with the first mounting hole 374 and the first mounting matching hole 311 to fix the driving member 31 and the mounting bracket 37 .

[0103] The first fastener cooperates with the first mounting hole 374 and the first mounting matching hole 311 to provide a stable fixing method for the driving member 31 and the mounting bracket 37, thereby improving the stability of the water tray assembly. The first fastener may be a screw.

[0104] Optionally, combined Figure 2 and Figure 4 As shown, the mounting bracket 37 is provided with a second mounting hole 375, the water receiving tray 10 is provided with a second mounting matching hole 13, and the water receiving tray assembly also includes a second fastener, which cooperates with the second mounting hole 375 and the second mounting matching hole 13 to fix the mounting bracket 37 and the water receiving tray 10.

[0105] The cooperation between the second fastener and the second mounting hole 375 and the second mounting matching hole 13 provides a stable fixing method for the mounting bracket 37 and the water receiving tray 10, which can improve the stability of the water receiving tray assembly. The second fastener can be a screw.

[0106] Optionally, combined Figure 5 and Figure 7 As shown, the water receiving tray assembly for the air conditioner also includes a first detection element and a control unit 40. The first detection element is arranged on the water receiving tray 10, and is used to detect the amount of water in the water receiving tray 10; the control unit 40 is connected to both the first detection element and the driving device 30, and is used to control the driving device 30 to drive the drain plug 20 to move toward the open position when the amount of water in the water receiving tray 10 is greater than the preset water amount.

[0107] The water receiving tray 10 defines a water holding space, and the preset water volume may be the maximum volume of the water holding space, or may be less than the maximum volume of the water holding space.

[0108] The water volume in the water receiving tray 10 is detected by the first detection element. When the water volume in the water receiving tray 10 is greater than the preset water volume, the control unit 40 automatically controls the driving device 30 to drive the drain plug 20 to move toward the open position, thereby realizing the automatic opening of the drain plug 20, reducing the need for manual intervention and improving the reliability of drainage. The first detection element and the control unit 40 cooperate with the driving device 30 to form an automatic control system, which can effectively prevent the water receiving tray 10 from overflowing due to excessive water.

[0109] Optionally, the first detection element is a water level sensor, which is used to detect the water level in the water receiving tray 10 .

[0110] The water level sensor can directly reflect the amount of water in the water tray 10 by detecting the water level in the water tray 10, monitor the water level changes in the water tray 10 in real time, and provide accurate water volume information. For example, the water level detector includes a float, and the float detects the water level, and the float rises with the water level. When the float rises to a certain height, the controller determines that the amount of water in the water tray 10 is greater than the preset water volume, and controls the driving device 30 to drive the drain plug 20 to move toward the open position.

[0111] Optionally, the first detection element is a pressure sensor, which is used to detect the pressure of the water receiving tray 10 to determine the water level in the water receiving tray 10 .

[0112] Since the water pressure is proportional to the water level, the pressure sensor can indirectly measure the water level and provide accurate water volume information to the control unit 40. The pressure sensor can continuously monitor the pressure change in the water receiving tray 10 and reflect the increase or decrease of the water level in real time.

[0113] Optionally, combined Figure 5 and Figure 7 As shown, the water tray assembly for the air conditioner also includes a second detection element 41 and a control unit 40. The second detection element 41 is arranged on the driving device 30, and is used to detect the operating parameters of the driving device 30; the control unit 40 is connected to both the second detection element 41 and the driving device 30, and is used to control the opening and closing of the driving device 30 according to the operating parameters of the driving device 30.

[0114] The second detection element 41 can detect the operating parameters of the driving device 30 in real time, such as detecting the resistance of the current flowing through the driving device 30, or detecting the temperature of the driving device 30. The control unit 40 can determine whether the driving of the driving device 30 encounters resistance based on the detection information, and further determine whether the drain plug 20 has moved to the open position or the closed position.

[0115] When the resistance increases or the temperature rises, it can be determined that the driving of the driving device 30 is blocked, so as to determine that the drain plug 20 has moved to the open position or the closed position, and the control unit 40 controls the driving device 30 to stop working. When the driving member 31 drives the first transmission member 32 to drive the second transmission member 33 to the open position or the closed position, the second transmission member 33 encounters resistance and cannot continue to move, so that the first transmission member 32 encounters resistance, and the second detection element 41 detects the signal that the driving of the driving device 30 is blocked, and the circuit where the driving device 30 is located is powered off, so that the driving member 31 stops running.

[0116] It is understandable that the water tray assembly for the air conditioner may also be provided with a micro switch instead of the second detection element 41. The micro switch is connected to the second transmission member 33 to limit the moving distance of the second transmission member 33. The micro switch can provide a stable limit function and provide accurate limit at a specific moving distance, so that the second transmission member 33 can accurately reach the open position or the closed position.

[0117] Optionally, combined Figure 5 and Figure 7 As shown, the water tray assembly for the air conditioner further includes a power supply unit 42, and the power supply unit 42 is connected to both the control unit 40 and the driving device 30 to form a loop.

[0118] When the drain plug 20 needs to be moved to the open position or the closed position, the control unit 40 controls the power supply unit 42 to close the circuit, providing a stable power supply to the drive device 30, and can control the drive device 30 to drive the drain plug 20 to move toward the open position or toward the closed position. When the drain plug 20 has moved to the open position or the closed position, the control unit 40 controls the power supply unit 42 to disconnect the circuit, so that the drive device 30 is powered off and the drain plug 20 stops working.

[0119] Exemplarily, the driving member 31 is a rotary motor. When the drain hole 11 needs to be opened, the control unit 40 controls the rotary motor to rotate forward, and the rotary motor drives the second transmission member 33 to drive the drain plug 20 to move toward the open position, thereby opening the drain hole 11, and the water in the water receiving tray 10 flows to the external space through the drain hole 11. After the second transmission member 33 moves to abut against the mounting bracket 37, the second detection unit receives the resistance signal, the second detection unit is disconnected, and the rotary motor stops rotating. At the same time, a disconnection signal is transmitted to the control unit 40. After the switch of the control unit 40 is disconnected, the second detection unit is closed and continues to detect the operating parameters of the driving device 30. When the drain hole 11 needs to be closed, the control unit 40 controls the rotary motor to rotate in the opposite direction, and the rotary motor drives the screw 321 to drive the nut 34 to move toward the closed position, thereby driving the drain plug 20 to close the drain hole 11. The drain plug 20 moves to seal with the drain hole 11, the second detection unit receives the motor resistance signal, the second detection unit is disconnected, and the rotary motor stops rotating. At the same time, a disconnect signal is transmitted to the control unit 40. After the switch of the control unit 40 is disconnected, the second detection unit is closed, completing a cycle of the drain plug 20 opening and closing the drain hole 11.

[0120] The disclosed embodiment provides an air conditioner, including an indoor unit 50, wherein the indoor unit 50 includes an evaporator and a water receiving tray assembly for the air conditioner as described in any one of the above embodiments, wherein the water receiving tray 10 is disposed below the evaporator to receive condensed water generated by the evaporator.

[0121] A partial schematic diagram of the water tray assembly being assembled to the indoor unit 50 is shown in FIG. Figure 1 and Figure 3 shown.

[0122] The air conditioner provided in the embodiment of the present disclosure includes the water receiving tray assembly for an air conditioner described in any one of the above embodiments, and thus has all the beneficial effects of the water receiving tray assembly for an air conditioner described in any one of the above embodiments, which will not be repeated here.

[0123] Optionally, the air conditioner further includes a remote controller, which is connected to the driving device 30 and is used to control the opening and closing of the driving device 30 .

[0124] The remote controller can wirelessly control the driving device 30 to drive the drain plug 20 to open or close the drain hole 11. The remote controller makes the motion control of the drain plug 20 simple, safe and reliable. When the air conditioner is an embedded air conditioner, the operation of the remote controller can avoid the hidden danger of operation caused by the embedded air conditioner being too high from the ground.

[0125] Optionally, the air conditioner further comprises a remote control signal receiving unit, which is connected to the control unit 40 and configured to receive a remote control signal from a remote controller. The control unit 40 can control the opening and closing of the driving device 30 according to the remote control signal.

[0126] When the control unit 40 does not receive a remote control signal, the circuit where the drive device 30 is located is in a disconnected state, the drive device 30 is closed, and the drain plug 20 is in a closed position. When the control unit 40 receives a remote control signal to open the drain plug 20, the circuit where the drive device 30 is located is closed, and the motor drives the screw 321 to rotate and drive the nut 34 to move upward, thereby driving the drain plug 20 to move to the open position, so that the drain plug 20 can open the drain hole 11, and the water in the water receiving tray 10 flows to the external space through the drain hole 11. When the control unit 40 receives a remote control signal to close the drain plug 20, the circuit where the drive device 30 is located is closed, and the drive member 31 drives the screw 321 to rotate and drive the nut 34 to move downward, thereby driving the drain plug 20 to move to the closed position, so that the drain plug 20 can close the drain hole 11.
