However, each air valve in this structure still requires a separate motor drive to control opening and closing, resulting in high structural costs. In addition, during maintenance, the installation components must be pulled out horizontally and the connecting components must be disconnected, so the air valve requires a larger maintenance operation space and the operation is cumbersome and inconvenient, resulting in poor maintenance operability and low maintenance efficiency.

[0051] Reference below Figure 1-Figure 12 A door assembly 1 according to an embodiment of the present invention is described.

[0052] like Figure 1 and Figure 2 As shown, the door assembly 1 for an air conditioner according to the present invention comprises a housing 11, a first door body 12, a second door body 13, a driving member 14 and a transmission assembly 15. The housing 11 of the present invention can provide a mounting position for some other components in the door assembly 1, and support, fix and protect some other components in the door assembly 1. The housing 11 is formed with a first opening and a second opening, and outside air can flow into or out of the air conditioner through the first opening and the second opening to achieve normal operation of the air conditioner; the first door body 12 of the present invention is arranged on the housing 11, and the first door body 12 can move relative to the housing 11 to selectively open or close the first opening. The second door body 13 is arranged on the shell body 11, and the second door body 13 can move relative to the shell body 11 to selectively open or close the second opening; the driving member 14 of the present invention is arranged on the shell body 11 and is provided with an output shaft, and the driving member 14 can drive the output shaft to rotate; the transmission assembly 15 of the present invention has the function of transmitting power and changing torque. Under the drive of the output shaft, the transmission assembly 15 can drive one of the first door body 12 and the second door body 13 to open, and drive the other of the first door body 12 and the second door body 13 to close, thereby realizing the control of the circulation state between the first opening and the second opening and the outside air.

[0053] The door assembly 1 of the present invention is provided with a shell 11, a first door body 12, a second door body 13, a driving member 14 and a transmission assembly 15, so that the first door body 12 is movably arranged on the shell 11 and can selectively open or close the first opening, and the second door body 13 is movably arranged on the shell 11 and can selectively open or close the second opening, and the transmission assembly 15 can be driven by the output shaft of the driving member 14 to drive one of the first door body 12 and the second door body 13 to open, and drive the other of the first door body 12 and the second door body 13 to close, so that the first door body 12 opens and closes the first opening and the second door body 13 opens and closes the second opening, and the same driving member 14 drives the transmission assembly 15 to control, thereby meeting the working requirements that the first opening and the second opening need to alternately circulate with the outside air, while reducing the number of driving members 14 used, improving the utilization rate of the driving member 14, and saving economic costs. Compared with the related art, each air valve needs a separate motor drive to control the opening and closing, which leads to high cost. In addition, during maintenance, the installation components need to be pulled out in the horizontal direction and the connection components need to be disconnected, resulting in large space occupied by maintenance operations, poor maintenance operability and low maintenance efficiency. The first door body 12 and the second door body 13 in the present invention share the same driving member 14, and there is no need to set up a second driving member 14 separately, so that the number of driving members 14 in the present invention can be smaller, which saves more economic costs. In addition, the first door body 12 and the second door body 13 in the present invention are arranged on the shell 11, which can reduce the assembly and disassembly steps of the door assembly 1 structure, improve the assembly and maintenance efficiency, and when it is necessary to maintain the components installed on the shell 11, the corresponding components can be disassembled and assembled along the height direction of the shell 11 to reduce the operating space required for maintenance, thereby further improving the maintenance convenience of the door assembly 1.

[0054] In addition, in a specific embodiment of the present invention, the shell 11 is formed with a first cavity and a second cavity spaced apart in the height direction of the shell 11, and the first cavity and the second cavity are respectively open toward the same end on the thickness direction of the shell 11, and the open ends of the first cavity and the second cavity are respectively constructed as a first opening and a second opening, and the first door body 12 and the second door body 13 are respectively accommodated in the first cavity and the second cavity, so that the first door body 12 can selectively open or close the second opening, and the second door body 13 can selectively open or close the second opening, thereby ensuring that the first cavity and the second cavity can selectively circulate with the outside air, thereby meeting the working requirements of the air conditioner.

[0055] In another specific embodiment of the present invention, the first cavity and the second cavity are respectively provided with Figure 1The first seal 16 and the second seal 17 shown in the figure, when the first door body 12 is in the position of closing the first opening, the first seal 16 can improve the air tightness between the first door body 12 and the first cavity; when the second door body 13 is in the position of closing the second opening, the second seal 17 can improve the air tightness between the second door body 13 and the second cavity.

[0056] According to one embodiment of the present invention, the transmission assembly 15 is provided with an input end, and the input end is connected to the output shaft, and the transmission assembly 15 is also provided with a first output end and a second output end linked to the input end, the first output end is connected to the first door body 12, and the second output end is connected to the second door body 13, so that the output shaft power of the driving member 14 can be transmitted to the first output end and the second output end by the input end of the transmission assembly 15 respectively; wherein, the first output end is suitable for driving the second door body 13 to keep the second opening closed when the first door body 12 is driven to move in the direction of opening the first opening, and the second output end is suitable for driving the first door body 12 to keep the first opening closed when the second door body 13 is driven to move in the direction of opening the second opening, that is, when the first opening is in a fully open state, the second opening is in a fully closed state, and when the second opening is in a fully open state, the first opening is in a fully closed state, and the first opening and the second opening are not in a fully open state at the same time, and the first opening and the second opening are alternately in a fully open state, which can change the air path flowing through the indoor heat exchanger of the humidity adjustment treatment room of the air conditioner, so as to realize the switching of the air conditioner to dehumidification operation and humidification operation. Therefore, by providing the transmission component 15 with an input end, a first output end and a second output end, the first output end is connected to the first door body 12, and the second output end is connected to the second door body 13, so that the first output end and the second output end can drive the first opening and the second opening to open alternately to ensure the normal operation of the air conditioner, and because the input end of the transmission component 15 is connected to the output shaft of the driving member 14, and the first output end and the second output end are respectively linked to the input end of the transmission component 15, it is achieved that the movement of the first door body 12 and the movement of the second door body 13 are driven by the same driving member 14, thereby improving the utilization rate of the driving member 14 and saving economic costs.

[0057] According to one embodiment of the present invention, the first output end and the second output end rotate synchronously and have the same rotation direction. When the power of the driving member 14 is transmitted from the output shaft to the input end of the transmission assembly 15, the first output end and the second output end are respectively linked with the input end and rotate. At this time, the first output end and the second output end rotate synchronously, and the first output end and the second output end have the same rotation direction, so that the first output end can drive the first door body 12 to rotate, and the second output end can drive the second door body 13 to rotate, and the first door body 12 and the second door body 13 rotate in the same direction. By setting the first output end and the second output end to rotate synchronously and in the same direction, when the first output end drives the first door body 12 to rotate in the direction of opening the first opening, the second output end can rotate synchronously and in the same direction as the first output end to drive the second door body 13 to rotate in the direction of closing the second opening. Correspondingly, when the second output end drives the second door body 13 to rotate in the direction of opening the second opening, the first output end can rotate synchronously and in the same direction as the second output end to drive the first door body 12 to rotate in the direction of closing the first opening, thereby achieving the first opening and the second opening being alternately in a fully open state, thereby meeting the working requirements when the air conditioner is switched between dehumidification operation and humidification operation.

[0058] like Figure 1 , Figure 2 and Figure 8As shown, according to one embodiment of the present invention, the transmission assembly 15 includes an input gear 151, a first transmission gear 152, a first torque limiter 1541, a second transmission gear 153 and a second torque limiter 1551. In this embodiment, the input gear 151 is linked with the output shaft and is configured as an input end. The input gear 151 can rotate under the linkage action of the output shaft; in this embodiment, the first transmission gear 152 is linked with the input gear 151, and when the input gear 151 rotates, it can drive the first transmission gear 152 to rotate; in this embodiment, the input end of the first torque limiter 1541 is connected to the first transmission gear 152, and the output end of the first torque limiter 1541 is connected to the first door body 12. When the input gear 151 drives the first transmission gear 152 to rotate, the torque of the first transmission gear 152 can be transmitted through the first torque limiter 15 41 is transmitted to the first door body 12; in this embodiment, the second transmission gear 153 is linked with the input gear 151, and when the input gear 151 rotates, the second transmission gear 153 can be driven to rotate, and the second transmission gear 153 has the same rotation direction as the first transmission gear 152; in this embodiment, the input end of the second torque limiter 1551 is connected to the second transmission gear 153, and the output end of the second torque limiter 1551 is connected to the second door body 13. When the input gear 151 drives the second transmission gear 153 to rotate, the torque of the second transmission gear 153 can be transmitted to the second door body 13 through the second torque limiter 1551. In this embodiment, the first torque limiter 1541 and the second torque limiter 1551 are respectively provided with a set torque. When the torque applied to the first torque limiter 1541 or the second torque limiter 1551 exceeds the set torque, the first torque limiter 1541 or the second torque limiter 1551 can be idling in the form of slipping to eliminate the torque, thereby realizing the overload protection of the transmission assembly 15 and the door assembly 1.

[0059] By setting the input gear 151, the first transmission gear 152, the first torque limiter 1541, the second transmission gear 153 and the second torque limiter 1551, the first transmission gear 152 and the second transmission gear 153 are respectively linked to the input gear 151, and the input end and the output end of the first torque limiter 1541 are respectively connected to the first transmission gear 152 and the first door body 12, and the input end and the output end of the second torque limiter 1551 are respectively connected to the second transmission gear 153 and the second door body 13, so that when the output shaft torque of the driving member 14 is transmitted to the input gear 151, the torque of the input gear 151 can have two transmission paths, and the first path is: input gear 151→first transmission gear 152→first torque limiter 1541→second A door body 12, and the second transmission path is: input gear 151→second transmission gear 153→second torque limiter 1551→second door body 13. The first path and the second path of torque transmission can respectively control the first door body 12 to open and close the first opening and control the second door body 13 to open and close the second opening, thereby achieving that the same driving member 14 can control the first opening and the second opening to be alternately in an open state. Since the gear transmission has the characteristics of high transmission accuracy, high efficiency, reliable transmission, compact structure and long service life, the present embodiment also achieves improved working reliability and working efficiency of the transmission assembly 15, extended service life of the transmission assembly 15 and the door assembly 1, and saves the installation space occupied by the transmission assembly 15, which is beneficial to the volume optimization of the door assembly 1 and the air conditioner.

[0060] like Figure 3 , Figure 5 and Figure 7 As shown, in this embodiment, the housing 11 is provided with a first stopper 111 and a second stopper 112, the first stopper 111 is provided at the first opening, the first stopper 111 is suitable for limiting the rotation of the first door body 12 in the first direction when in the closed state, the second stopper 112 is provided at the second opening, the second stopper 112 is suitable for limiting the rotation of the second door body 13 in the second direction when in the closed state, the first direction is opposite to the second direction. By providing the first stopper 111 and the second stopper 112, when the first door body 12 opens the first opening, under the limiting action of the second stopper 112, the second door body 13 cannot rotate in the second direction at the position of closing the second opening, thereby realizing that when the first opening is opened, the second opening can be stably kept in the closed state; when the second door body 13 opens the second opening, under the limiting action of the first stopper 111, the first door body 12 cannot rotate in the first direction at the position of closing the first opening, thereby realizing that when the second opening is opened, the first opening can be stably kept in the closed state.

[0061] It can be understood that when the first door body 12 keeps the first opening closed under the limiting action of the first limiter 111, the torque transmitted to the first door body 12 by the first torque limiter 1541 can be eliminated in the form of idling after the torque of the first torque limiter 1541 exceeds the set torque, so that the first torque limiter 1541 can prevent the first door body 12 and the transmission assembly 15 from overloading, thereby improving the working safety of the door assembly 1; similarly, when the second door body 13 keeps the second opening closed under the limiting action of the second limiter 112, the torque transmitted to the second door body 13 by the second torque limiter 1551 can be eliminated in the form of idling after the torque of the second torque limiter 1551 exceeds the set torque, thereby preventing the second door body 13 and the transmission assembly 15 from overloading, thereby improving the working safety of the door assembly 1.

[0062] In addition, in a specific embodiment of the present invention, the first transmission gear 152 includes: Figure 8 The first idle gear 1521 and the first driving gear 1522 shown in the figure are meshed with the input gear 151 for transmission, the first driving gear 1522 is meshed with the first idle gear 1521 for transmission and connected to the input end of the first torque limiter 1541; the second transmission gear 153 includes a second idle gear 1531 and a second driving gear 1532, the second idle gear 1531 is meshed with the input gear 151 for transmission, the second driving gear 1532 is meshed with the second idle gear 1531 for transmission and connected to the input end of the second torque limiter 1551. The first idle gear 1521 and the second idle gear 1531 can respectively make the transmission between the input gear 151 and the first driving gear 1522 and between the input gear 151 and the second driving gear 1532 more stable and smooth, thereby helping to improve the working efficiency and working reliability of the transmission assembly 15.

[0063] According to one embodiment of the present invention, a third limit member 113 and a fourth limit member 114 are provided on the shell 11, the third limit member 113 is provided at the first opening, and the third limit member 113 is suitable for limiting the rotation of the first door body 12 toward the second direction in the open state, and the fourth limit member 114 is provided at the second opening, and the fourth limit member 114 is suitable for limiting the rotation of the second door body 13 toward the first direction in the open state. By setting the third limit member 113 and the fourth limit member 114, when the first door body 12 is rotated to the position where the first opening is opened, the third limit member 113 can limit the first door body 12 from rotating toward the second direction, thereby achieving that the first door body 12 can stably keep the first opening in an open state; when the second door body 13 is rotated to the position where the second opening is opened, the fourth limit member 114 can limit the second door body 13 from rotating toward the first direction, thereby achieving that the second door body 13 can stably keep the second opening in an open state, thereby improving the position control accuracy of the door assembly 1 for the first door body 12 and the second door body 13, which helps to optimize the working stability and performance of the door assembly 1 and the air conditioner.

[0064] The first limiting member 111 , the second limiting member 112 , the third limiting member 113 and the fourth limiting member 114 can jointly limit the rotational positions of the first door body 12 and the second door body 13 . During the operation of the air conditioner, when the first door body 12 rotates to the position where the first opening is fully opened, the second door body 13 is in the position where the second opening is fully closed. At this time, the third limiter 113 can limit the first door body 12 from rotating toward the second direction, so that the first door body 12 can maintain the open state of the first opening, and the second limiter 112 can limit the second door body 13 from rotating toward the second direction, so that the second door body 13 can maintain the closed state of the second opening; when the second door body 13 rotates to the position where the second opening is fully opened, the first door body 12 is in the position where the first opening is fully closed. At this time, the fourth limiter 114 can limit the second door body 13 from rotating toward the first direction, so that the second door body 13 can maintain the open state of the second opening, and the first limiter 111 can limit the first door body 12 from rotating toward the first direction, so that the first door body 12 can maintain the closed state of the first opening. Therefore, the first stopper 111, the second stopper 112, the third stopper 113 and the fourth stopper 114 ensure that the first opening and the second opening can be stably in an alternating open state, thereby effectively improving the working performance of the air conditioner.

[0065] like Figure 1 , Figure 2 and Figure 8As shown, according to one embodiment of the present invention, the transmission assembly 15 further includes a first one-way clutch 1542 and a second one-way clutch 1552. In this embodiment, the input end of the first one-way clutch 1542 is connected to the first transmission gear 152, the output end of the first one-way clutch 1542 is connected to the input end of the first torque limiter 1541, the output end of the first one-way clutch 1542 can rotate relative to the input end in the first direction, and the output end of the first one-way clutch 1542 can rotate synchronously relative to the input end in the second direction; in this embodiment, the input end of the second one-way clutch 1552 is connected to the second transmission gear 153, the output end of the second one-way clutch 1552 is connected to the input end of the second torque limiter 1551, the output end of the second one-way clutch 1552 rotates relative to the input end in the second direction, and the input end of the second one-way clutch 1552 rotates synchronously relative to the output end in the first direction.

[0066] By setting the first one-way clutch 1542 and the second one-way clutch 1552, the first one-way clutch 1542 is set between the first transmission gear 152 and the first torque limiter 1541, and the second one-way clutch 1552 is set between the second transmission gear 153 and the second torque limiter 1551, so that when the output shaft of the driving member 14 stops rotating, the torque generated by the first door body 12 rotating in the first direction to close the first opening can be eliminated by the relative rotation of the output end of the first one-way clutch 1542 relative to the input end in the second direction, so that the torque generated by the first door body 12 will not be transmitted back to the first transmission gear 152, thereby achieving the first door body 12 returning to the state of closing the first opening. opening position, the first one-way clutch 1542 can play a good role in preventing the first transmission gear 152, the input gear 151 and the output shaft from being damaged; similarly, when the output shaft of the driving member 14 stops rotating, the second door body 13 rotates in the second direction to close the second opening. The torque generated can be eliminated by the relative rotation of the output end of the second one-way clutch 1552 relative to the input end in the second direction, so that the torque generated by the second door body 13 will not be transmitted back to the second transmission gear 153, thereby achieving that when the second door body 13 returns to the position of closing the second opening, the second one-way clutch 1552 can play a good role in preventing the second transmission gear 153, the input gear 151 and the output shaft from being damaged.

[0067] like Figure 4 and Figure 8As shown, according to one embodiment of the present invention, the transmission assembly 15 further includes a first reset member 156 and a second reset member 157. One end of the first reset member 156 is connected to the first door body 12, and the other end of the first reset member 156 is connected to the housing 11. One end of the second reset member 157 is connected to the second door body 13, and the other end of the second reset member 157 is connected to the housing 11. By providing the first reset member 156 and the second reset member 157, when the output shaft of the driving member 14 stops rotating, the first reset member can provide power to the first door body 12 to drive the first door body 12 to rotate and return to the position of fully closing the first opening, and the second reset member can provide power to the second door body 13 to drive the second door body 13 to rotate and return to the position of fully closing the second opening, so that no matter the output shaft stops rotating when the first opening is opened, or the output shaft stops rotating when the second opening is opened, under the action of the first reset member 156 and the second reset member 157, the first opening and the second opening are finally in a fully closed state.

[0068] In some embodiments, if the first opening or the second opening is not in a completely closed state after the output shaft stops rotating, due to the pressure difference between the outside and the inside of the air conditioner and the wind flow of the outside, cold or humid outside air may enter the inside of the air conditioner through the first opening or the second opening, resulting in condensation inside the air conditioner, causing damage to the internal components of the air conditioner and the growth of bacteria in the air conditioner, etc. The bacteria growing in the air conditioner are easily spread to the room through the air, resulting in a decrease in indoor air quality and endangering human health; in addition, after the cold or humid outside air enters the inside of the air conditioner through the first opening or the second opening, the relative humidity difference between the outside air and the humidity control element in the air conditioner may cause the humidity control element to absorb a large amount of moisture. In this state, if the air conditioner restarts the dehumidification operation, the humidity of the humidified air supplied by the air conditioner is large due to the large amount of moisture absorption by the humidity control element, so that the discomfort index in the room will increase a lot. Therefore, in the present invention, when the output shaft stops rotating, the first return member and the second return member make the first opening and the second opening return to a completely closed state, which can protect the air conditioner itself, optimize the use effect of the air conditioner, and enhance the user experience.

[0069] In addition, in a specific embodiment of the present invention, the first return member 156 and the second return member 157 are respectively constructed as springs. Since springs have the advantages of high elasticity, good durability and low cost, by constructing the first return member 156 and the second return member 157 as springs, it is beneficial to improve the working performance and service life of the first return member and the second return member, and save economic costs.

[0070] According to one embodiment of the present invention, the set torque of the first torque limiter 1541 and / or the second torque limiter 1551 is greater than the output torque of the output shaft of the driving member 14. When the torque applied to the first torque limiter 1541 or the second torque limiter 1551 exceeds the set torque, the first torque limiter 1541 or the second torque limiter 1551 will idle in the form of slipping to eliminate the overload torque and protect the transmission assembly 15 and the door assembly 1. Therefore, by setting the set torque of the first torque limiter 1541 and / or the second torque limiter 1551 to be greater than the output torque of the output shaft of the driving member 14, when the torque on the first torque limiter 1541 and / or the second torque limiter 1551 does not exceed the output torque of the output shaft of the driving member 14, the first torque limiter 1541 and / or the second torque limiter 1551 will be free from the output torque of the output shaft of the driving member 14. The limiter 1541 and the second torque limiter 1551 can respectively transmit the power of the driving member 14 continuously to the first door body 12 and the second door body 13 to realize the normal operation of the first door body 12 and the second door body 13; when the torque on the first torque limiter 1541 and / or the second torque limiter 1551 exceeds the set torque, at this time, the torque of the first torque limiter 1541 and / or the second torque limiter 1551 is greater than the output torque of the output shaft, the first torque limiter 1541 and / or the second torque limiter 1551 will slip and idle to eliminate the overload torque, thereby improving the transmission safety of the transmission assembly 15.

[0071] In addition, in a specific embodiment of the present invention, the restoring torque of the first reset member 156 and / or the second reset member 157 is smaller than the output torque of the output shaft of the driving member 14, so that only when the output shaft of the driving member 14 stops rotating, the first reset member 156 or the second reset member 157 can drive the first door body 12 to rotate in the direction of closing the first opening or drive the second door body 13 to rotate in the direction of closing the second opening, so as to block the circulation between the first opening and the second opening and the outside air, thereby protecting the air conditioner and optimizing the working performance of the air conditioner.

[0072] According to one embodiment of the present invention, the first output end and the second output end rotate synchronously and in opposite directions. When the power of the driving member 14 is transmitted from the output shaft to the input end of the transmission assembly 15, the first output end and the second output end are respectively linked with the input end and rotate. At this time, the first output end and the second output end rotate synchronously, and the first output end and the second output end rotate in opposite directions, so that the first output end can drive the first door body 12 to rotate, and the second output end can drive the second door body 13 to rotate, and the first door body 12 and the second door body 13 rotate in opposite directions. By setting the first output end and the second output end to rotate synchronously and in opposite directions, when the first output end drives the first door body 12 to rotate in the direction of opening the first opening, the second output end can rotate synchronously and in the opposite direction with the first output end to drive the second door body 13 to rotate in the direction of closing the second opening. Correspondingly, when the second output end drives the second door body 13 to rotate in the direction of opening the second opening, the first output end can rotate synchronously and in the opposite direction with the second output end to drive the first door body 12 to rotate in the direction of closing the first opening, thereby achieving the first opening and the second opening being alternately in a fully open state, thereby meeting the working requirements when the air conditioner is switched between dehumidification operation and humidification operation.

[0073] According to an embodiment of the present invention, the transmission assembly 15 includes an input gear 151, a first transmission gear 152, a second transmission gear 153, a first one-way clutch 1542, and a second one-way clutch 1552. In this embodiment, the input gear 151 is linked with the output shaft and is configured as an input end. The input gear 151 can rotate under the linkage of the output shaft; in this embodiment, the first transmission gear 152 is linked with the input gear 151, and when the input gear 151 rotates, it can drive the first transmission gear 152 to rotate; in this embodiment, the second transmission gear 153 is linked with the input gear 151, and when the input gear 151 rotates, it can drive the second transmission gear 153 to rotate, and the second transmission gear 153 rotates in the opposite direction to the first transmission gear 152; in this embodiment, the input end of the first one-way clutch 1542 is connected to the first transmission gear 152. Then, the output end of the first one-way clutch 1542 is connected to the first door body 12, the output end of the first one-way clutch 1542 rotates relative to the input end in the first direction, and the output end of the first one-way clutch 1542 rotates synchronously with the input end in the second direction; in this embodiment, the input end of the second one-way clutch 1552 is connected to the second transmission gear 153, the output end of the second one-way clutch 1552 is connected to the second door body 13, the output end of the second one-way clutch 1552 rotates relative to the input end in the first direction, and the output end of the second one-way clutch 1552 rotates synchronously with the input end in the second direction.

[0074] By setting the input gear 151, the first transmission gear 152, the second transmission gear 153, the first one-way clutch 1542 and the second one-way clutch 1552, the first transmission gear 152 and the second transmission gear 153 are respectively linked to the input gear 151, and the input end and the output end of the first one-way clutch 1542 are respectively connected to the first transmission gear 152 and the first door body 12, and the input end and the output end of the second one-way clutch 1552 are respectively connected to the second transmission gear 153 and the second door body 13, so that when the output shaft torque of the driving member 14 is transmitted to the input gear 151, the torque of the input gear 151 can have two transmission paths, and the first path is: input gear 151→first transmission gear 152→first one-way clutch 1542→second A door body 12, and the second transmission path is: input gear 151→second transmission gear 153→second one-way clutch 1552→second door body 13. The first path and the second path of torque transmission can respectively control the first door body 12 to open and close the first opening and control the second door body 13 to open and close the second opening, thereby achieving that the same driving member 14 can control the first opening and the second opening to be alternately in an open state. Moreover, since the gear transmission has the characteristics of high transmission accuracy, high efficiency, reliable transmission, compact structure and long service life, the present embodiment also achieves the improvement of the working reliability and working efficiency of the transmission assembly 15, the extension of the service life of the transmission assembly 15 and the door assembly 1, and the saving of the installation space occupied by the transmission assembly 15, which is beneficial to the volume optimization of the door assembly 1 and the air conditioner.

[0075] In addition, by setting the first one-way clutch 1542 and the second one-way clutch 1552, the first one-way clutch 1542 is set between the first transmission gear 152 and the first door body 12, and the second one-way clutch 1552 is set between the second transmission gear 153 and the second door body 13, so that when the output shaft of the driving member 14 stops rotating, the torque generated by the first door body 12 rotating in the first direction to close the first opening can be eliminated by the relative rotation of the output end of the first one-way clutch 1542 relative to the input end in the first direction, so that the torque generated by the first door body 12 will not be transmitted back to the first transmission gear 152, thereby achieving the first door body 12 returning to the position of closing the first opening. At the same time, the first one-way clutch 1542 can play a good role in preventing damage to the first transmission gear 152, the input gear 151 and the output shaft; similarly, when the output shaft of the driving member 14 stops rotating, the torque generated by the second door body 13 rotating in the first direction to close the second opening can be eliminated by the output end of the second one-way clutch 1552 rotating relative to the input end in the first direction, so that the torque generated by the second door body 13 will not be transmitted back to the second transmission gear 153, thereby achieving that when the second door body 13 returns to the position of closing the second opening, the second one-way clutch 1552 can play a good role in preventing damage to the second transmission gear 153, the input gear 151 and the output shaft.

[0076] In addition, in a specific embodiment of the present invention, the first transmission gear 152 includes: Fig.10 The third idle gear 1523 and the third driving gear 1524 shown in the figure are meshed with the input gear 151 for transmission, the third driving gear 1524 is meshed with the third idle gear 1523 for transmission and connected to the input end of the first one-way clutch 1542; the second transmission gear 153 is meshed with the input gear 151 for transmission and connected to the input end of the second one-way clutch 1552. By arranging the third idle gear 1523 between the input gear 151 and the third driving gear 1524, and making the second transmission gear 153 directly meshed with the input gear 151 for transmission, when the input gear 151 rotates, the third idle gear 1523 can make the third driving gear 1524 rotate in the opposite direction to the second transmission gear 153, thereby realizing that the same driving member 14 can control the first opening and the second opening to be alternately opened.

[0077] According to one embodiment of the present invention, the transmission assembly 15 further includes a first torque limiter 1541 and a second torque limiter 1551. In this embodiment, the input end of the first torque limiter 1541 is connected to the output end of the first one-way clutch 1542, and the output end of the first torque limiter 1541 is connected to the first door body 12; in this embodiment, the input end of the second torque limiter 1551 is connected to the output end of the second one-way clutch 1552, and the output end of the second torque limiter 1551 is connected to the second door body 13. By providing the first torque limiter 1541 and the second torque limiter 1551, when the torque transmitted to the first torque limiter 1541 or the second torque limiter 1551 in the transmission assembly 15 exceeds the set torque, the first torque limiter 1541 or the second torque limiter 1551 can be idling in the form of slipping to eliminate the torque, thereby realizing the overload protection of the transmission assembly 15 and the door assembly 1.

During the operation of the air conditioner, when the first door body 12 is rotated to the position where the first opening is fully opened, the second door body 13 is in the position where the second opening is fully closed. At this time, the seventh limiter 117 can limit the first door body 12 from rotating in the second direction, so that the first door body 12 can maintain the first opening. The sixth stopper 116 can limit the second door body 13 from rotating toward the first direction, so that the second door body 13 can maintain the closed state of the second opening; when the second door body 13 rotates to the position of fully opening the second opening, the first door body 12 is in the position of fully closing the first opening, at this time, the eighth stopper 118 can limit the second door body 13 from rotating toward the second direction, so that the second door body 13 can maintain the open state of the second opening, and the fifth stopper 115 can limit the first door body 12 from rotating toward the first direction, so that the first door body 12 can maintain the closed state of the first opening. Therefore, the fifth stopper 115, the sixth stopper 116, the seventh stopper 117 and the eighth stopper 118 ensure that the first opening and the second opening can be stably in an alternating open state, thereby effectively improving the working performance of the air conditioner.
