[0064] Please refer to Figures 1 to 7In this embodiment, the indoor unit 100 includes an upper base module 110 and a lower base module 130 detachably mounted on the upper base module 110. The upper base module 110 includes an upper base 111, a water outlet cover 112, an outdoor connecting pipe 113 and a heat exchanger 114. The heat exchanger 114 is installed in the upper base 111. A through installation slide is provided on one side of the upper base 111, and the water outlet cover 112 is movably mounted on the installation slide. The water outlet cover 112 is provided with a flow channel 115, and the flow channel 115 has a first interface 116 and a second interface 117 that are connected. One end of the outdoor connecting pipe 113 is connected to the second interface 117, and the other end extends out of the upper base module 110 to drain water outward. The lower base module 130 includes a lower base 131 and a water receiving tray 132 arranged in the lower base 131, and one side of the water receiving tray 132 is provided with a connecting pipe 133 corresponding to the first interface 116. A plugging piece 134 is provided in the connecting pipe 133. When the lower base module 130 is assembled to the upper base module 110, the water receiving tray 132 is located below the heat exchanger 114, and the connecting pipe 133 is plugged into the first interface 116, and the plugging piece 134 is in an open state. Before the lower base module 130 is removed, the water outlet end cover 112 can be slid outward to disengage the first interface 116 from the connecting pipe 133, and the plugging piece 134 can seal the connecting pipe 133. After the lower base module 130 is installed on the upper base module 110, the water outlet end cover 112 can be slid inward to plug the first interface 116 from the connecting pipe 133, and the plugging piece 134 can be opened, so that the water in the water receiving tray 132 can flow into the water outlet end cover 112 through the connecting pipe 133.

[0065] In this embodiment, the water outlet cover 112 is movably mounted on the water outlet chute of the upper base 111, and a connecting pipe 133 is provided on one side of the water receiving tray 132, so that the water outlet cover 112 can be easily separated from the water receiving tray 132 by sliding the water outlet cover 112 outward, so that the removal of the lower base module 130 can be facilitated. Most importantly, the present application provides a blocking member 134 in the connecting pipe 133, and before the lower base module 130 is removed, the water outlet cover 112 can be slid outward to disengage the first interface 116 from the connecting pipe 133, and the blocking member 134 can seal the connecting pipe 133, thereby preventing the water in the water receiving tray 132 from leaking from the connecting pipe 133 when the lower base module 130 is removed. After the lower base module 130 is installed on the upper base module 110, sliding the water outlet cover 112 inward can allow the connecting pipe 133 to be inserted into the first interface 116 and the blocking member 134 to be opened, so that the water in the water receiving tray 132 can flow into the water outlet cover 112 through the connecting pipe 133, thereby facilitating drainage.

[0066] It should be noted that the lower base module 130 is assembled on the upper base module 110, which means that the lower base module 130 is completely assembled on the upper base module 110 and can work normally. The lower base module 130 is installed on the upper base module 110, which means that after the lower base 131 is removed, the lower base 131 and the upper base 111 are only mechanically fixed during installation, and the outlet cover 112 is not connected to the connecting pipe 133.

[0067] It should also be noted that the lower base module 130 is generally installed on the upper base module 110 through a snap interface or a hook structure. The upper base 111 is used as a mounting carrier of the upper base module 110, and the crossflow blade drive motor and heat exchanger 114 of the indoor unit 100 are generally mounted on the upper base 111. The lower base 131 is used as a mounting carrier of the lower base module 130, and the water receiving tray 132 and crossflow blades of the indoor unit 100 are generally mounted on the lower base 131.

The water outlet cover 112 is provided with a driving unit 118 at the position of the first interface 116. When the connecting pipe 133 is plugged into the first interface 116, the driving unit 118 can push the valve plate 135 open. When the connecting pipe 133 is pulled out of the first interface 116, the valve plate 135 can be movably closed.

[0069] In this embodiment, the valve plate 135 is movably arranged in the connection pipe 133, and the driving part 118 is arranged at the position of the water outlet cover 112 located at the first interface 116, so that when the connection pipe 133 is plugged into the first interface 116, the driving part 118 can push the valve plate 135 open. When the connection pipe 133 is pulled out of the first interface 116, the valve plate 135 can be automatically closed, so that the opening and closing of the valve plate 135 is associated with the movement of the water outlet cover 112, and no operation is required, which is simpler to use.

[0070] In this embodiment, the valve plate 135 is rotatably installed in the connecting tube 133. The driving part 118 is a push rod 119 disposed in the first interface 116. When the connecting tube 133 is plugged into the first interface, the push rod 119 will extend into the connecting tube 133 and push the valve plate 135 to rotate so that the valve plate 135 is opened. When the connecting tube 133 is pulled out of the first interface, the push rod 119 withdraws from the connecting tube 133, and the valve plate 135 can be movably closed.

[0071] In this embodiment, the driving device is a push rod 119, and the push rod 119 is arranged in the first interface 116.

When the connecting tube 133 is pulled out, the push rod 119 will also withdraw from the connecting tube 133, so that the valve plate 135 will be closed.

[0072] Please refer to Figures 1 to 7 In this embodiment, the top of the valve plate 135 is hinged to the connecting pipe 133; when the connecting pipe 133 is pulled out of the first interface, the valve plate 135 can be moved and closed under the action of gravity.

[0073] In this embodiment, the top of the valve plate 135 is hinged to the connecting pipe 133 , so that when the connecting pipe 133 is pulled out of the first interface 116 , the valve plate 135 can be closed by gravity, which is more convenient and easy to implement.

[0074] In this embodiment, the size of the valve plate 135 is smaller than the inner diameter of the connecting pipe 133. A sealing ring 136 is provided in the connecting pipe 133. The valve plate 135 is rotatably provided on a side of the sealing ring 136 close to the water receiving tray 132. When the valve plate 135 is in a closed state, the valve plate 135 abuts against the sealing ring 136.

[0075] In this embodiment, the diameter of the valve plate 135 is set smaller than the inner diameter of the connecting pipe 133, so that the valve plate 135 can be opened to a larger opening. A sealing ring 136 is set in the connecting pipe 133. When the connecting pipe 133 is pulled out, the valve plate 135 falls and abuts against the sealing ring 136 to achieve sealing.

The shape of the first interface 116 may also be set to a corresponding rectangular shape. In this way, the valve plate 135 may be set to a rectangular shape, which is more convenient for rotation in the up and down directions, and the sealing ring stage 136 may not be provided.

[0077] Please refer to Figures 1 to 7 Furthermore, a mounting seat 137 is provided on the inner wall of the connecting pipe 133 located on the upper side of the sealing ring platform 136 close to the water receiving tray 132 , and the valve plate 135 is rotatably mounted on the mounting seat 137 .

[0078] In this embodiment, a mounting seat 137 is provided on the inner side of the sealing ring 136 to rotatably mount the valve plate 135, so that the valve can be rotated inwardly to open under the action of the push rod 119, and rotated outwardly to abut against the sealing ring 136 to achieve sealing when closed.

[0079] In this embodiment, a torsion spring is disposed between the valve plate 135 and the mounting seat 137 , and the torsion spring can close the valve plate 135 when the connected pipe 133 is pulled out of the first interface 116 .

[0080] In this embodiment, a torsion spring is arranged between the valve plate 135 and the mounting seat 137, and the torsion spring can apply external force to the valve plate 135 to improve the sealing effect between the valve plate 135 and the sealing ring 136. At the same time, it can also avoid the problem of the valve plate 135 opening due to shaking left and right when the lower base module 130 is removed.

[0081] In this embodiment, the first interface 116 is arranged on the inner end surface of the water outlet end cover 112, and the second interface 117 is arranged on the side wall of the water outlet end cover 112 and is connected to the first interface 116. That is to say, the flow channel 115 of the water outlet end cover 112 is L-shaped rotated 90° clockwise. The top rod 119 is convexly arranged on the end surface of the first interface 116 close to the second interface 117. The top rod 119 is convexly arranged on the end surface of the first interface 116 close to the second interface 117, that is, the bottom wall of the first interface 116, and also the side wall of the second interface 117.

One end of the connecting rod 122 is hinged to the water outlet cover 112, and the other end is hinged to the locking plate 121. By rotating the locking plate 121 in a direction away from the upper base 111, the water outlet cover 112 can be pulled outward by the connecting rod 122. By rotating the locking plate 121 in a direction close to the upper base 111, the water outlet cover 112 can be pushed inward by the connecting rod 122.

[0085] In this embodiment, by providing the locking plate 121 and the connecting rod 122, the water outlet cover 112 can be pushed and pulled from the outside in a convenient and labor-saving manner.

[0086] In summary, the working principles and beneficial effects of the indoor unit 100 and the air conditioner provided in this embodiment are:
