DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] First embodiment

[0027] See also Figure 1This embodiment provides an indoor unit 100. In the indoor unit 100 provided by this embodiment, during the process of removing the mounting base 120 from the air duct assembly 150, the sealing assembly 110 can automatically seal the first connecting terminal 130 under the drive of the mounting base 120. The operation is simple and convenient, and the risk of water entering the first connecting terminal 130 can be reduced, thereby improving the safety of the water-washing indoor unit 100.

[0028] As the market's requirements for the health performance of air conditioners are increasing, the easy-to-disassemble and washable function of the indoor unit 100 of the air conditioner is receiving more and more attention. In order to achieve the washable function of the cross-flow fan and the air duct of the indoor unit 100 without removing the motor, it is usually necessary to waterproof the connection terminals during the disassembly process, that is, after the connection terminals are disconnected, manually cover the connection terminals with sealing covers, and finally wash them with water. Sealing the connection terminals in this way is cumbersome and it is easy to forget to cover the sealing covers, causing water to enter the connection terminals during the process of washing the air duct, posing a safety hazard. The indoor unit 100 provided in this embodiment can improve the above-mentioned problem, and can automatically seal the connection terminals during the disassembly process. The connection terminals can be sealed without manual operation by the operator. The operation is simple and convenient, and can reduce the risk of water entering the connection terminals, thereby improving the safety of the water-washable indoor unit 100.

[0029] In this embodiment, the indoor unit 100 includes a mounting base 120, a sealing assembly 110, a first connecting terminal 130, a second connecting terminal 140 and an air duct assembly 150. The second connecting terminal 140 is installed on the mounting base 120, the first connecting terminal 130 is installed on the air duct assembly 150, the mounting base 120 and the air duct assembly 150 are detachably connected, the first connecting terminal 130 and the second connecting terminal 140 are detachably electrically connected, the sealing assembly 110 is rotatably connected to the air duct assembly 150 and is connected to the mounting base 120, and the sealing assembly 110 is used to seal the first connecting terminal 130 when the mounting base 120 and the air duct assembly 150 are released.

[0030] In this embodiment, the first connection terminal 130 is mounted on the air duct assembly 150, and the second connection terminal 140 is mounted on the mounting base 120. During the process of disassembling the indoor unit 100, the mounting base 120 is removed from the air duct assembly 150. During the process of disassembling the mounting base 120, the mounting base 120 moves away from the air duct assembly 150, driving the sealing assembly 110 to move, so that the sealing assembly 110 seals the first connection terminal 130. In this embodiment, during the process of disassembling the mounting base 120 from the air duct assembly 150, the sealing assembly 110 can automatically seal the first connection terminal 130 under the drive of the mounting base 120. This operation is simple and convenient, and can reduce the risk of water intrusion into the first connection terminal 130, thereby improving the safety of the water-washing indoor unit 100.

[0031] See also Figure 2 In this embodiment, a fixing portion 152 is provided on the air duct assembly 150, and the fixing portion 152 has a fixing groove 154. The first connecting terminal 130 is installed in the fixing groove 154, and the sealing assembly 110 is rotatably connected to the fixing portion 152. When the mounting base 120 and the air duct assembly 150 are released from fixation, the sealing assembly 110 cooperates with the opening of the fixing groove 154, thereby sealing the first connecting terminal 130.

[0032] In this embodiment, the first connection terminal 130 is installed in the fixing groove 154. When the mounting base 120 and the air duct assembly 150 are fixedly connected, the second connection terminal 140 extends into the fixing groove 154 and electrically connects with the first connection terminal 130, thereby sealing the first connection terminal 130 and the second connection terminal 140. When the mounting base 120 and the air duct assembly 150 are disconnected, the second connection terminal 140 disengages from the fixing groove 154, opening the opening of the fixing groove 154. At this time, the sealing assembly 110 cooperates with the opening of the fixing groove 154 to seal the fixing groove 154, thereby sealing the first connection terminal 130 accommodated in the fixing groove 154.

[0033] See also Figure 3 In this embodiment, the sealing assembly 110 includes a sealing plate 112 and a connecting member 114. The sealing plate 112 is fixedly connected to the connecting member 114. The connecting member 114 is rotatably connected to the air duct assembly 150 and is connected to the mounting base 120. When the mounting base 120 and the air duct assembly 150 are released from fixation, the sealing plate 112 moves toward the direction close to the first connecting terminal 130, thereby sealing the first connecting terminal 130.

[0034] In this embodiment, under the condition that the mounting base 120 is fixedly connected to the air duct assembly 150, the sealing plate 112 is arranged above the fixing groove 154. When the mounting base 120 is disconnected from the air duct assembly 150 and moves in the direction away from the air duct assembly 150, the end of the connecting member 114 connected to the mounting base 120 moves in the direction away from the air duct assembly 150 under the drive of the mounting base 120, causing the sealing plate 112 to move in the direction close to the air duct assembly 150, that is, the sealing plate 112 moves in the direction of the fixing groove 154 until it cooperates with the opening of the fixing groove 154, sealing the fixing groove 154, thereby sealing the first connecting terminal 130 installed in the fixing groove 154.

[0035] In this embodiment, the connecting member 114 includes a mutually rotating connecting plate 1142 and a connecting rod 1144, the end of the connecting plate 1142 away from the connecting rod 1144 is connected to the sealing plate 112, the end of the connecting rod 1144 away from the connecting plate 1142 is connected to the mounting seat 120, and the end of the connecting plate 1142 away from the connecting rod 1144 is rotatably connected to the air duct assembly 150.

[0036] In this embodiment, the connecting plate 1142 is movably connected to the connecting rod 1144, and the connecting plate 1142 is rotationally connected to the fixing portion 152. During the process of disconnecting the mounting seat 120 from the air duct assembly 150, the mounting seat 120 drives the connecting rod 1144 to move away from the air duct assembly 150, and the sealing plate 112 moves toward the direction close to the fixing groove 154, cooperating with the opening of the fixing groove 154, thereby sealing the first connecting terminal 130.

[0037] See also Figure 4 In this embodiment, the mounting base 120 is provided with a mounting hole 122, and the connecting rod 1144 is installed in the mounting hole 122. The end of the connecting rod 1144 away from the connecting plate 1142 is installed in the mounting hole 122. When the mounting base 120 moves away from the air duct assembly 150, the connecting rod 1144 cooperates with the mounting hole 122, so that the mounting base 120 can move in the direction away from the air duct assembly 150 under the drive of the mounting base 120.

[0038] In this embodiment, the mounting base 120 includes a main body 124, a first stop plate 126 and a second stop plate 128. The first stop plate 126 and the second stop plate 128 are spaced apart on the main body 124, and the second stop plate 128 is arranged close to the air duct assembly 150. The connecting member 114 also includes a stop portion 1146, which is arranged between the first stop plate 126 and the second stop plate 128.

[0039] In this embodiment, mounting holes 122 are provided on both the first stop plate 126 and the second stop plate 128. The mounting hole 122 on the first stop plate 126 is coaxially arranged with the mounting hole 122 on the second stop plate 128, so that the connecting rod 1144 can pass through the mounting hole 122 of the second stop plate 128 and the mounting hole 122 of the first stop plate 126 in sequence.

[0040] The stopper 1146 is disposed between the first stopper plate 126 and the second stopper plate 128 . The first stopper plate 126 and the second stopper plate 128 can limit the stopper 1146 in a direction approaching the air duct assembly 150 and in a direction away from the air duct assembly 150 .

[0041] For example, when the mounting base 120 moves away from the air duct assembly 150, the mounting base 120 first moves away from the air duct assembly 150 until the stop portion 1146 abuts against the second stop plate 128, and then the mounting base 120 drives the connecting rod 1144 to move away from the air duct assembly 150.

[0042] Similarly, during the process of the mounting seat 120 moving toward the direction close to the air duct assembly 150, the mounting seat 120 moves toward the direction close to the air duct assembly 150 until the stop portion 1146 abuts against the first stop plate 126, and then the mounting seat 120 drives the connecting rod 1144 to move toward the direction close to the air duct assembly 150.

[0043] It is easy to understand that to prevent the stopper 1146 from disengaging from the mounting hole 122, the width of the mounting hole 122 should be smaller than the width of the stopper 1146. If the mounting hole 122 is circular, the stopper 1146 is also circular, that is, the diameter of the mounting hole 122 should be smaller than the diameter of the stopper 1146. If the mounting hole 122 and the stopper 1146 are of other shapes, it is sufficient to ensure that the maximum width of the mounting hole 122 is smaller than the minimum width of the stopper 1146, so that the stopper 1146 can move between the first stop plate 126 and the second stop plate 128.

[0044] Similarly, to ensure that connecting rod 1144 can slide up and down within mounting hole 122, the dimensions of connecting rod 1144 should be smaller than the shape of mounting hole 122. If mounting hole 122 and connecting rod 1144 are circular, the diameter of mounting hole 122 should be larger than the diameter of connecting rod 1144 to allow connecting rod 1144 to move within mounting hole 122. If mounting hole 122 and connecting rod 1144 have other shapes, it is sufficient to ensure that the dimensions of mounting hole 122 are larger than the dimensions of connecting rod 1144.

[0045] In this embodiment, it can be considered that the first stop plate 126, the second stop plate 128 and the main body 124 form a sliding channel 129, the stop portion 1146 is installed in the sliding channel 129, the stop portion 1146 can slide in the sliding channel 129, and the size of the sliding channel 129 is larger than the size of the mounting hole 122.

[0046] In this embodiment, the connecting member 114 further includes an elastic portion 1148 , which is disposed between the stopping portion 1146 and the first stopping plate 126 .

[0047] In this embodiment, the elastic portion 1148 is sleeved on the connecting rod 1144 and disposed between the first stop plate 126 and the stop portion 1146. When the mounting base 120 is removed from the duct assembly 150, the mounting base 120 moves away from the duct assembly 150. The stop portion 1146 first abuts against the second stop plate 128, thereby driving the connecting rod 1144 to move away from the duct assembly 150, causing the sealing plate 112 to seal the opening of the fixing groove 154. After cleaning the air duct assembly 150, when the mounting seat 120 moves toward the air duct assembly 150, the stop portion 1146 first abuts against the first stop plate 126 through the elastic portion 1148, and the connecting rod 1144 drives the sealing plate 112 to move away from the fixing groove 154 through the connecting plate 1142. When the sealing plate 112 has moved to the extreme position and the mounting seat 120 continues to move toward the air duct assembly 150, since the sealing plate 112 has moved to the extreme position, the elastic portion 1148 is gradually compressed until the mounting seat 120 is fixedly connected to the air duct assembly 150.

[0048] When the mounting base 120 needs to be removed from the air duct assembly 150 again, after the mounting base 120 and the air duct assembly 150 are released, the mounting base 120 moves away from the air duct assembly 150 under the action of the restoring force of the elastic part 1148, thereby facilitating the operator's operation and simplifying the disassembly process.

[0049] See also Figure 5 and Figure 6 In this embodiment, a connecting portion 156 is provided on the fixing portion 152 , the sealing assembly 110 includes a rotating portion 116 , and the indoor unit 100 further includes a connecting member 114 , and the connecting portion 156 is rotatably connected to the rotating portion 116 via the connecting member 114 .

[0050] In this embodiment, the rotating part 116 is fixedly connected to the connecting plate 1142, that is, the rotating part 116 is installed on the connecting plate 1142, and the rotating part 116 is rotatably connected to the connecting part 156. Under the action of the connecting rod 1144, the sealing plate 112 can be driven to move toward or away from the fixed groove 154 through the connecting plate 1142.

[0051] In this embodiment, the indoor unit 100 further includes a rotating member 160 . The connecting portion 156 is provided with a connecting hole 158 , and the rotating portion 116 is provided with a rotating hole 118 . The rotating member 160 cooperates with the connecting hole 158 and the rotating hole 118 .

[0052] In this embodiment, the rotating member 160 connects the rotating hole 118 and the connecting hole 158, thereby rotatably connecting the rotating portion 116 and the connecting portion 156, so that the sealing plate 112 can rotate relative to the fixed portion 152, and the sealing plate 112 can open or close the opening of the fixed groove 154, thereby achieving sealing of the first connecting terminal 130.

[0053] In this embodiment, the rotating member 160 includes a rotating shaft 162 and a torsion spring 164. The rotating shaft 162 cooperates with the connecting hole 158 and the rotating hole 118. The torsion spring 164 is sleeved on the rotating shaft 162. One end of the torsion spring 164 abuts against the connecting portion 156, and the other end of the torsion spring 164 abuts against the connecting plate 1142.

[0054] As connecting plate 1142 drives sealing plate 112 away from fixing portion 152, connecting plate 1142 presses against torsion spring 164 toward connecting portion 156, compressing torsion spring 164. Specifically, when the sealing cover is disengaged from the opening of fixing slot 154, torsion spring 164 is compressed. Simultaneously, when mounting base 120 and duct assembly 150 are unfastened, the restoring force of torsion spring 164 causes connecting plate 1142 to move away from fixing portion 152, thereby moving sealing plate 112 toward fixing slot 154. This allows sealing plate 112 to seal the opening of fixing slot 154, thereby sealing first connecting terminal 130 mounted within fixing slot 154.

[0055] It is easy to understand that the end of the torsion spring 164 away from the connecting plate 1142 is abutted against the connecting part 156. Since the connecting part 156 is installed on the fixing part 152, in other embodiments, the end of the torsion spring 164 away from the connecting plate 1142 can be abutted against the fixing part 152, thereby realizing compression and reset of the torsion spring 164.

[0056] In this embodiment, the torsion spring 164 is disposed between the connecting portion 156 and the rotating portion 116 .

[0057] In this embodiment, the torsion spring 164 is sleeved on the connecting shaft. The torsion spring 164 is set between the connecting part 156 and the rotating part 116. The rotating part 116 and the connecting part 156 can limit the torsion spring 164 to prevent the torsion spring 164 from falling off the connecting shaft.

[0058] In this embodiment, there are two rotating parts 116 , the two rotating parts 116 are arranged at an interval, and the connecting part 156 is arranged between the two rotating parts 116 .

[0059] In order to improve the connection effect between the rotating part 116 and the connecting part 156, two rotating parts 116 are arranged on the connecting plate 1142, and the two rotating parts 116 are arranged at intervals. The connecting part 156 is arranged between the two rotating parts 116, and the rotating shaft 162 passes through the rotating hole 118 of one of the rotating parts 116, the connecting hole 158 of the connecting part 156 and the rotating hole 118 of the other rotating part 116 in sequence, thereby connecting the two rotating parts 116 and the connecting part 156.

[0060] In this embodiment, the connecting portion 156 is disposed between the two rotating portions 116 . When the rotating shaft 162 fixes the rotating portion 116 and the connecting portion 156 , the stability between the connecting plate 1142 and the fixing portion 152 can be improved.

[0061] In order to improve the effect of the restoring force of the torsion spring 164, there are also two torsion springs 164, and the two torsion springs 164 are respectively arranged on both sides of the connecting part 156, that is, there is a torsion spring 164 between the connecting part 156 and each rotating part 116. When the mounting seat 120 and the air duct assembly 150 are released, the two torsion springs 164 can use a larger restoring force to make the sealing plate 112 move toward the direction close to the fixed wiper, thereby reducing the burden on the operator and simplifying the operation process.

[0062] In this embodiment, a limiting groove 159 is defined on the connecting portion 156 , and a clamping portion 166 is defined on one end of the torsion spring 164 away from the connecting plate 1142 . The clamping portion 166 is clamped in the limiting groove 159 .

[0063] In this embodiment, in order to improve the fixing effect of the torsion spring 164, the clamping portion 166 of the torsion spring 164 is set in the limiting groove 159, and the clamping portion 166 of the torsion spring 164 is limited by the limiting groove 159 to prevent the torsion spring 164 from being disengaged from the connection portion 156.

[0064] Among them, since there are two torsion springs 164, the clamping parts 166 of the two torsion springs 164 are both set in the limiting groove 159. In order to improve the fixing effect between the torsion spring 164 and the limiting groove 159, the clamping parts 166 of the two torsion springs 164 can be fixedly connected. The two torsion springs 164 can limit each other and improve the fixing effect between the torsion spring 164 and the connecting part 156.

[0065] In this embodiment, the limiting groove 159 is provided near the fixing portion 152. The limiting groove 159 is provided below the connecting portion 156, which can maximize the length of the end of the torsion spring 164 connected to the connecting portion 156, thereby increasing the restoring force storage of the torsion spring 164 when it is compressed.

[0066] In this embodiment, the connecting portion 156 is disposed near the opening of the fixing groove 154. Similarly, the provision of the connecting portion 156 at the opening of the fixing groove 154 enables the sealing plate 112 to directly engage with the opening of the fixing groove 154 under the drive of the connecting plate 1142. That is, the connecting plate 1142 and the sealing plate 112 can be aligned on the same straight line, and the sealing plate 112 and the connecting plate 1142 can have the same shape, thereby reducing the manufacturing process of the sealing plate 112 and the connecting plate 1142.

[0067] The operating principle of the indoor unit 100 provided in this embodiment is as follows: In this embodiment, when the mounting base 120 is fixedly connected to the air duct assembly 150, the elastic portion 1148 and the torsion spring 164 are both in a compressed state. If the mounting base 120 and the air duct assembly 150 are released, the restoring force of the elastic portion 1148 causes the mounting base 120 to move away from the air duct assembly 150, facilitating removal of the mounting base 120. The restoring force of the torsion spring 164 causes the sealing plate 112 to move toward the fixing groove 154, allowing the sealing plate 112 to seal the fixing groove 154 and facilitate removal of the mounting base 120. After the air duct assembly 150 is cleaned, during the process of installing the mounting base 120 to the air duct assembly 150, the operator drives the mounting base 120 to move toward the direction close to the air duct assembly 150, and the connecting rod 1144 pushes the connecting plate 1142 to move toward the direction close to the fixing portion 152, causing the sealing plate 112 to move away from the fixing groove 154, and the torsion spring 164 is continuously compressed. When the torsion spring 164 is compressed to the limit position, if the mounting base 120 continues to move toward the direction close to the air duct assembly 150, the elastic portion 1148 is continuously compressed until the mounting base 120 is installed on the air duct assembly 150.

[0068] In summary, the indoor unit 100 provided in this embodiment has the first connection terminal 130 mounted on the air duct assembly 150, and the second connection terminal 140 mounted on the mounting base 120. During disassembly of the indoor unit 100, the mounting base 120 is removed from the air duct assembly 150. During disassembly of the mounting base 120, the mounting base 120 moves away from the air duct assembly 150, driving the sealing assembly 110 to move, thereby sealing the first connection terminal 130. In this embodiment, during disassembly of the mounting base 120 from the air duct assembly 150, the sealing assembly 110 can automatically seal the first connection terminal 130 under the drive of the mounting base 120. This operation is simple and convenient, and the risk of water intrusion into the first connection terminal 130 can be reduced, thereby improving the safety of the water-washing indoor unit 100.
