A second enclosed chamber 137 is formed inside the second sealing area 13, and the second enclosed chamber 137 is used to accommodate the wiring terminal 2. The wiring terminal 2 is used to electrically connect the electrical components provided on the casing of the cabinet air-conditioning indoor unit to the power supply module. The electrical components include, for example, at least one of a display screen and a control button, and the power supply module is, for example, a controller or a storage device of the cabinet air-conditioning indoor unit.

[0052] In a preferred embodiment, Figure 1-Figure 4 As shown, the second sealing area 13 includes a box body 131 and a box cover 132, the box body 131 has an opening, the box cover 132 is openably arranged at the opening, and the box cover 132 cooperates with the box body 131 to form a second closed chamber 137. Exemplarily, a plurality of ribs are arranged at a position corresponding to the second sealing area 13 of the main body part 11, and the plurality of ribs are enclosed to form the box body 131.

[0053] In a preferred embodiment, the box cover 132 includes a connecting end 1323 and a snap-on end 1324 that are arranged opposite to each other. The connecting end 1323 is integrally formed with the box body 131. The box cover 132 is rotatably connected to the box body 131 via the connecting end 1323, and the box cover 132 is snap-connected to the box body 131 via the snap-on end 1324. The connecting end 1323 is rotatably connected to the box body 131, and the snap-on end 1324 is snap-connected to the box body 131. The connecting end 1323 and the snap-on end 1324 can be both ends of the box cover 132 in the height direction or the width direction of the box cover 132, which is not specifically limited here. For example, Figure 1 and Figure 2As shown, one of the box cover 132 and the box body 131 is provided with a buckle 136, and the other of the box cover 132 and the box body 131 is provided with a buckle hole 135, and the buckle 136 cooperates with the buckle hole 135 to realize the opening and closing of the box body 131 by the box cover 132, and the wiring terminal 2 can be repeatedly disassembled and assembled, thereby improving the convenience of after-sales maintenance of the wiring terminal 2. In other achievable ways, the box body 131 and the box cover 132 can also be a split structure, and the connecting end 1323 of the box cover 132 is hinged to the box body 131 through a hinge, and the buckle end 1324 of the box cover 132 and the box body 131 can also be fixed by screws or spring buckles.

[0054] In this embodiment, by setting the first sealing area 12 and the second sealing area 13 on the main part 11 of the cover structure 1, when the cover structure 1 is assembled with the upper air outlet frame 3, the driving component 4 and the terminal block 2 arranged on the upper air outlet frame 3 can be sealed respectively to prevent the entry of external condensed water, while improving the assembly efficiency and reducing the difficulty of after-sales maintenance. The cover structure 1 of this embodiment can be designed on the basis of the original wind sweeping motor cover, and the driving component 4 and the terminal block 2 can be sealed and protected by designing an integrated structure including the first sealing area 12 and the second sealing area 13, while not increasing the mold opening cost of the whole machine, and not affecting the assembly efficiency of the whole machine.

[0055] In some embodiments, Figure 1-Figure 4 As shown, a fixing support 134 is provided in the box body 131, and the fixing support 134 is used to fix the wiring terminal 2 in the second closed chamber 137, and the wiring terminal 2 is spaced apart from the inner wall surface of the box body 131, so as to reduce the coldness of the inner wall surface of the box body 131 transferred to the wiring terminal 2 while fixing the wiring terminal 2, thereby reducing the generation of condensed water of the wiring terminal 2. In a preferred embodiment, the fixing support 134 includes a support plate 1341, which is provided on the bottom wall of the box body 131 and extends along the height direction of the box body 131. The support plate 1341 divides the box body 131 into a first sub-chamber 1313 and a second sub-chamber 1314 along the width direction of the main part 11, and the support plate 1341 is provided with a fixing hole 1342. The wiring terminal 2 includes a first butt terminal 21 and a second butt terminal 22 for plug-in matching, and the first butt terminal 21 is fixed in the fixing hole 1342. Preferably, the support plate 1341 is arranged in the middle of the box body 131, and the fixing hole 1342 is opened in the middle position of the support plate 1341 to increase the distance between the terminal 2 and the bottom wall and the surrounding side walls of the box body 131, reduce the influence of the cold amount radiated from the upper air outlet frame 3 to the bottom wall and the surrounding side walls of the box body 131 on the terminal 2, and further improve the insulation effect on the terminal 2.

[0056] In other achievable embodiments, the fixed support member 134 includes a fixed column arranged on the bottom wall of the box body 131, and a clamp is provided at one end of the fixed column away from the bottom wall of the box body 131, and the terminal 2 is fixed to the end of the fixed column away from the bottom wall of the box body 131 through the clamp.

[0057] When the cover structure 1 of this embodiment is used in the application scenario of a cabinet-type air conditioner indoor unit, such as Fig.14 As shown, after the upper air outlet frame 3 and the air inlet component 52 are assembled, the second sealing area 13 of the cover structure 1 is entirely exposed to the outside of the air inlet component 52. At this time, the box cover 132 can be opened to first fix the first docking terminal 21 of the wiring terminal 2 on the support plate 1341 inside the box body 131, and then the second docking terminal 22 is plugged into the first docking terminal 21, and then the box cover 132 is covered on the box body 131 to seal the wiring terminal 2, and finally the front panel 51 and the air inlet component 52 are buckled together as a whole.

[0058] Considering that the assembly effects of the air inlet component 52 and the upper air outlet frame 3 of different cabinet air conditioner indoor units are different, such as Fig.15 and Fig.16 As shown, after the upper air outlet frame 3 is assembled with the air inlet component 52, part of the second sealing area 13 of the cover structure 1 is hidden in the air inlet component 52, and the box cover 132 cannot be opened. In order to solve this technical problem, in some embodiments, such as Figure 4 As shown, the box cover 132 includes a first box cover 1321 and a second box cover 1322 which are independent of each other. The first box cover 1321 corresponds to the first sub-chamber 1313 to open and close the first sub-chamber 1313, and the second box cover 1322 corresponds to the second sub-chamber 1314 to open and close the second sub-chamber 1314. The first box cover 1321 and the second box cover 1322 can independently perform opening and closing actions. Preferably, the first box cover 1321 is integrally formed and arranged above the box body 131 and at a position corresponding to the first sub-chamber 1313, and the second box cover 1322 is integrally formed and arranged below the box body 131 and at a position corresponding to the second sub-chamber 1314, so as to reduce the difficulty of processing. The first box cover 1321 and the box body 131, as well as the second box cover 1322 and the box body 131 are fixed by buckles.

[0059] When the cover structure 1 of this embodiment is used in the application scenario of a cabinet-type air conditioner indoor unit, such as Fig.15 and Fig.16As shown, before the upper air outlet frame 3 is assembled with the air inlet component 52, the first docking terminal 21 of the connection terminal 2 is first fixed to the support plate 1341 inside the box body 131, and then the first box cover 1321 is covered on the box body 131 to seal the first sub-chamber 1313. After the upper air outlet frame 3 is assembled with the air inlet component 52, the first box cover 1321 and the first sub-chamber 1313 are hidden in the air inlet component 52 and cannot be opened, while the second box cover 1322 and the second sub-chamber 1314 are exposed outside the air inlet component 52. At this time, the second docking terminal 22 can be plugged and matched with the first docking terminal 21 after the second box cover 1322 is opened, and then the box cover 132 is covered on the box body 131 to seal the second sub-chamber 1314, and finally the front panel 51 and the air inlet component 52 are buckled into a whole.

[0060] In some embodiments, Figure 1-Figure 4 As shown, the side wall of the box body 131 is provided with a wiring hole 1315 for the wiring harness of the terminal block 2 to pass through, and the wiring hole 1315 is connected to the second closed chamber. This is to avoid the box cover 132 closing the box body 131 and squeezing the wiring harness. The setting position of the wiring hole 1315 on the side wall of the box body 131 corresponds to the wiring position of the wiring harness of the first docking terminal 21 and the second docking terminal 22 of the terminal block 2 in the box body 131. Exemplarily, wiring holes 1315 are respectively provided on both sides along the width direction of the main body part 11, so that the wiring harness of the first docking terminal 21 and the second docking terminal 22 of the terminal block 2 can pass through respectively. The wiring hole 1315 can be a circular hole opened in the middle position of the side wall of the box body 131, or it can be a semicircular hole opened in the side wall of the box body 131 away from one end of the bottom wall of the box body 131, which is not specifically limited here.

[0061] In some embodiments, Figure 1-Figure 4 As shown, the main body part 11 also has a drainage area 14, which is located between the first sealing area 12 and the second sealing area 13. The drainage area 14 includes a first drainage surface 141 and a second drainage surface 142. The first drainage surface 141 and the second drainage surface 142 are arranged in sequence from top to bottom along the height direction of the main body part 11, and the first drainage surface 141 is connected to the second drainage surface 142. A drainage cavity 146 is formed between the first drainage surface 141 and the second drainage surface 142. The first drainage surface 141 and the second drainage surface 142 are both inclined from the front side of the main body part 11 to the back side of the main body part 11 toward the direction close to the second sealing area 13. The inclination angle of the first drainage surface 141 relative to the horizontal plane is A, and the inclination angle of the second drainage surface 142 relative to the horizontal plane is B, satisfying: 0<B<A<90°, so that condensed water gathers in the drainage cavity 146. In this embodiment, a drainage area 14 is provided to collect condensed water generated on the surface of the cover structure 1 to prevent the condensed water from entering the first closed chamber, thereby further preventing the influence of the condensed water on the wiring terminal 2 and improving the reliability of the wiring terminal 2.

[0062] In a preferred embodiment, Figure 1-Figure 3 As shown, the drainage area 14 is provided with a lateral opening 144 on one side along the width direction of the main body part 11, and a side plate 145 is provided on the other side. The top wall of the box body 131 forms a second drainage surface 142, and the second drainage surface 142 is inclined from the side plate 145 to the lateral opening 144 toward the second sealing area 13, so that the water collected in the drainage cavity 146 can flow out through the lateral opening 144. In the application scenario of the upper air outlet frame 3, as shown in FIG. Figure 5-Figure 7 As shown, the lateral opening 144 is located at the back side of the upper air outlet frame 3 to prevent the condensed water flowing out of the lateral opening 144 from affecting the electrical components disposed on the front panel 51 .

[0063] Among other possible implementations, Figure 4 As shown, the first drainage surface 141 is provided with at least one drainage hole 143, and at least one drainage hole 143 is arranged close to the second drainage surface 142, and the condensed water located above the box body 131 flows out of the drainage cavity 146 from the back side of the cover structure 1 through at least one drainage hole 143. In the application scenario of the cabinet air conditioner indoor unit, the cabinet air conditioner indoor unit includes a heat exchanger and a water collecting device for receiving the condensed water of the heat exchanger, and a water flow channel is provided between the cover structure 1 and the water collecting device, and the condensed water flowing out from the lateral opening 144 or the drainage hole 143 can flow into the water collecting device through the water flow channel, and finally be discharged from the cabinet air conditioner indoor unit through a drain pipe connected to the water collecting device.

[0064] In some embodiments, Figure 1-Figure 3 As shown, the main body part 11 also has a first structural reinforcement area 15, which is located between the first sealing area 12 and the drainage area 14. The first structural reinforcement area 15 includes a first structural reinforcement cavity 151, and at least one first horizontal rib 152 and at least one first vertical rib 153 are arranged in the first structural reinforcement cavity 151. In this embodiment, the overall strength of the cover structure 1 can be significantly improved by setting the first structural reinforcement area 15 to compensate for the weakening effect of the drainage cavity 146 set in the concave shape on the strength of the cover structure 1. In other achievable ways, such as Figure 4 As shown, the overall strength of the cover structure 1 can be improved by providing at least one second transverse rib 147 and at least one second vertical rib 148 crisscrossing on the first drainage surface 141 .

[0065] In some embodiments, Figure 1-Figure 4As shown, the main body part 11 also has a third sealing area 16, which is located between the first sealing area 12 and the drainage area 14. The third sealing area 16 includes a second sealing cover 163, which is used to cooperate with the upper air outlet frame 3 to form a third closed chamber. The third closed chamber is used to accommodate the sterilization component 20, so as to prevent condensed water from affecting the sterilization effect of the sterilization component 20. The sterilization component 20 is, for example, a cold plasma device.
