[0052] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0053] Embodiment 1:

[0054] Combined with Figure 1-7 As shown, the embodiments of the present disclosure provide a wire pressing plate 10 for an air conditioner. The wire pressing plate 10 is used for an indoor unit. The indoor unit includes a chassis 20 and a motor 30.

[0055] The motor 30 is arranged on the chassis 20. The wire pressing plate 10 is installed on the chassis 20, and the surface of the wire pressing plate 10 facing the chassis 20 and the chassis 20 jointly enclose a wire routing groove 31 for the motor wire to pass through. Among them, the motor wire is connected to the motor 30.

[0056] Among them, as Figure 7 shown, along the direction away from the motor 30, the surface of the wire pressing plate 10 facing the chassis 20 (as Figure 1 shown at F) slopes downward.

[0057] The wire pressing plate 10 is installed on the chassis 20. The wire pressing plate 10 and the chassis 20 jointly enclose a wire routing groove 31 for the motor wire to pass through. The wire pressing plate 10 fixes the motor wire in the wire routing groove 31. Among them, the wire pressing plate 10 is designed as an inclined structure. One end of the wire pressing plate 10 close to the motor 30 is higher than one end of the wire pressing plate 10 away from the motor 30. Water can flow in the direction away from the motor 30 under the action of its own gravity, resulting in water not approaching the motor 30. In this way, water cannot drip on the motor 30 terminals, thereby preventing the motor 30 from short - circuiting, improving safety, and reducing the after - sales maintenance cost caused by short - circuiting.

[0058] Optionally, as shown in Figure 7 , in the direction away from the motor 30, the surface of the wire pressing plate 10 facing the chassis 20 gradually slopes downward.

[0059] The wire pressing plate 10 is higher in the direction close to the motor 30 and lower in the direction away from the motor 30, so that the wire pressing plate 10 has an inclined structure on the bottom plate and is a gradually inclined structure, making the water flow more smoothly along the wire pressing plate 10 in the direction away from the motor 30, so that the water can be discharged from the wire groove 31 in time, thereby the wire pressing plate 10 plays a role in protecting the motor 30.

[0060] Optionally, as shown in Figure 2 , a groove 1024 is formed by the depression of the surface of the wire pressing plate 10 facing the chassis 20. The groove 1024 and the chassis 20 jointly define the wire groove 31. Among them, in the direction away from the motor 30, the surface of the bottom wall 1021 of the groove 1024 facing the chassis 20 slopes downward.

[0061] A groove 1024 with an opening facing the chassis 20 is formed by the depression of the surface of the wire pressing plate 10 facing the chassis 20. The groove 1024 includes a bottom wall 1021, a first side wall 1022 and a second side wall 1023. The first side wall 1022 and the second side wall 1023 are arranged on opposite sides of the bottom wall 1021. The bottom wall 1021 and the first side wall 1022 are connected and a first bend 2043 is formed at the connection. The bottom wall 1021 and the second side wall 1023 are connected and a second bend 1053 is formed at the connection.

[0062] The air conditioner can be an embedded air conditioner. At this time, the chassis 20 is installed on the ceiling and is arranged above the wire pressing plate 10. In the direction away from the motor 30, the surface of the bottom wall 1021 of the groove 1024 facing the chassis 20 (that is, the upper surface of the bottom wall 1021 of the groove 1024) slopes downward, so that the water flowing into the groove 1024 can only flow out along the bottom wall 1021 to the lower place (the direction away from the motor 20), thereby preventing water droplets from dripping onto the motor 30, avoiding short - circuit of the motor circuit, improving safety, and reducing the after - sales maintenance cost caused by short - circuit.

[0063] Optionally, along the direction close to the bottom wall 1021 of the groove 1024, the surface of the side wall 1021 of the groove 1024 facing the chassis 20 slopes downward to form a guiding surface.

[0064] The groove sidewalls of the groove 1024 include a first groove sidewall 1022 and a second groove sidewall 1023. Along the direction close to the groove bottom wall 1021 of the groove 1024, the surfaces of the first groove sidewall 1022 and / or the second groove sidewall 1023 facing the chassis 20 are inclined downward to form a flow guiding surface, and the flow guiding surface has a guiding effect on the water flow. An angle greater than 90 degrees is formed between the groove sidewall and the groove bottom wall 1021. When water drops onto the groove sidewall, the water will flow along the flow guiding surface to the groove bottom wall 1021 under the action of its own gravity, and then flow along the groove bottom wall 1021 in the direction away from the motor 30, avoiding the water flowing to the motor 30.

[0065] Optionally, the chassis 20 is provided with a connection and cooperation part, and the wire pressing plate 10 is provided with a connection part connected to the connection and cooperation part. The connection and cooperation part cooperates with the connection part to position the wire pressing plate 10 on the chassis 20.

[0066] Optionally, the connection and cooperation part includes a first connection and cooperation part 201 and a second connection and cooperation part 202 provided on the chassis 20, and the connection part includes a first connection part 103 connected to the first connection and cooperation part 201 and a second connection part 104 connected to the second connection and cooperation part 202 provided on the wire pressing plate 10; wherein, the first connection part 103 and the second connection part 104 are respectively located on opposite sides of the wire routing groove 31.

[0067] As Figure 5 shown, through the cooperation of the first connection part 103 and the first connection and cooperation part 201, and the cooperation of the second connection part 104 and the second connection and cooperation part 202, the positioning between the wire pressing plate 10 and the chassis 20 is realized.

[0068] The first connection part 103 and the second connection part 104 are respectively located on opposite sides of the wire routing groove 31, and the first connection and cooperation part 201 and the second connection and cooperation part 202 are also located on opposite sides of the wire routing groove 31, so that the wire pressing plate 10 is evenly stressed at opposite sides of the wire routing groove 31, improving the stability and reliability of the connection between the wire pressing plate 10 and the chassis 20.

[0069] Optionally, as Figure 1 and Figure 2 shown, the wire pressing plate 10 of the air conditioner includes a wire bundling part 110 and an extension part 1103.

[0070] The wire bundling part 110 and the chassis 20 jointly enclose the wire routing groove 31, and the wire bundling part 110 includes the groove bottom wall 1021 and the groove sidewall of the groove.

[0071] The extension part is provided on one side of the wire bundling part 110, and the extension part and the wire bundling part 110 are arranged in sequence along the width direction of the wire routing groove 31.

[0072] Among them, the extending part extends in a direction away from the motor 30 and is inclined downward toward the surface of the chassis 20, or the extending part extends in a direction close to the wire trough 31 and is inclined downward toward the surface of the chassis 20 and is higher than the wire bundling part 110.

[0073] When the extending part extending in a direction away from the motor 30 is inclined downward toward the surface of the chassis 20 (the upper surface of the extending part), the water flow dripping onto the surface of the extending part toward the chassis 20 will flow away from the motor 30 under the action of its own gravity, avoiding the water flowing toward the motor 30.

[0074] It can also be that the extending part extending in a direction close to the wire trough 31 is inclined downward toward the surface of the chassis 20 and is higher than the wire bundling part 110. In this way, the height of the extending part near the wire bundling part 110 is lower than the height of the extending part far from the wire bundling part 110. The water flow dripping onto the extending part will flow toward the wire bundling part 110 under the action of its own gravity, and thus flow into the wire bundling part and flow away from the motor 30 along the bottom wall 1021 of the groove.

[0075] Taking the connection method of the connection part and the connection and cooperation part as screw connection as an example, the water on the ceiling will flow to the extending part through the screw hole (connection and cooperation part) on the chassis 20 and the screw hole (connection part) on the wire pressing plate 10. The water flowing into the extending part will flow away from the motor 30 along the inclined direction of the extending part.

[0076] The extending part 110 includes a first extending part 1101 and a second extending part 1102. The first extending part 1101 is arranged on one side of the wire bundling part 110, and the first connection part 103 is arranged on the first extending part 1101; the second extending part 1102 is arranged on the other side of the wire bundling part 110, and the second connection part 104 is arranged on the second extending part 1102.

[0077] Among them, the surface of the first extending part 1101 and / or the second extending part 1102 facing the chassis 20 is inclined downward in a direction away from the motor 30, or the surface of the first extending part 1101 and / or the second extending part 1102 facing the chassis 20 is inclined downward in a direction close to the wire trough 31 and is higher than the wire bundling part 110.

[0078] Optionally, as Figure 3 shown, the wire pressing plate 10 is provided with a wire dividing trough 303, and the wire dividing trough 303 is communicated with the wire trough 31.

[0079] A wire dividing trough 303 is provided on the wire pressing plate 10, and the wire dividing trough 303 is arranged on the second extending part 1102.

[0080] The second connection and mating part 201 includes a first sub-connection and mating part 2021 and a second sub-connection and mating part 2022. The second connection part 104 includes a first sub-connection part 1041 and a second sub-connection part 1042. The first sub-connection and mating part 2021 mates with the first sub-connection part 1041, such as by screw connection or snap connection. The second sub-connection and mating part 2022 mates with the second sub-connection part 1042, such as by screw connection or snap connection.

[0081] The first sub-connection part 1041 and the second sub-connection part 1042 are disposed on opposite sides of the wire dividing groove 303. The wire dividing groove 303 is in an arch shape and is in communication with the wire routing groove 31. The wire routing groove 31 is connected by a motor wire. After the motor wire enters from the first end 301 of the wire routing groove 31, it is divided into two parts. One part extends out from the second end 302 of the wire routing groove 31, and the other part can extend out from the wire dividing groove 303.

[0082] Alternatively, the motor wire can enter from the second end 302 of the wire routing groove 31 and be divided into two parts. One part extends out from the first end 301 of the wire routing groove 31, and the other part can extend out from the wire dividing groove 303.

[0083] Optionally, an embodiment of the present disclosure further provides an air conditioner, including an indoor unit. The indoor unit includes a chassis 20, a motor 30, and a wire pressing plate 10 for an air conditioner as described in any one of the above embodiments.

[0084] The motor 30 is disposed on the chassis 20. The wire pressing plate 10 is installed on the chassis 20. The surface of the wire pressing plate 10 facing the chassis 20 and the chassis 20 jointly define a wire routing groove 31 for the motor wire to pass through.

[0085] The air conditioner provided in this application includes a wire pressing plate as described in any one of the above embodiments, and thus has all the beneficial effects of the wire pressing plate as described in any one of the above embodiments, which will not be elaborated here.

[0086] Optionally, the motor 20 is disposed in the middle of the chassis 20. The chassis 20 is provided with a plurality of reinforcing ribs 32. The wire pressing plate 10 is at least partially disposed between two adjacent reinforcing ribs 32 and jointly defines a wire routing groove 31 with the part of the chassis 20 located between two adjacent reinforcing ribs 32, so that the setting of the wire pressing plate 10 does not affect the setting of the reinforcing ribs 32 on the chassis and does not damage the strength of the reinforcing ribs 32, and the space between two adjacent reinforcing ribs 32 is reasonably utilized.

[0087] As Figure 16 shown, a plurality of reinforcing ribs 32 are radially distributed around the motor 30, which can improve the structural strength of each part of the chassis 20.

[0088] At least part of the wire pressing plate 10 is provided with reinforcing ribs 32 to increase the structural strength of the chassis 20. The reinforcing ribs 32 on the chassis 20 can be integrally formed by stamping, with simple process and convenient manufacturing.

[0089] The chassis 20 is provided with a first connection and cooperation part 201 and a second connection and cooperation part 202. The first connection and cooperation part 201 is connected to the first connection part 103, and the second connection and cooperation part 202 is connected to the second connection part 104. Among them, the first connection and cooperation part 201 is arranged on the reinforcing rib 32, and the second connection and cooperation part 202 is arranged on the reinforcing rib 32 adjacent to the reinforcing rib 32 where the first connection and cooperation part 201 is located.

[0094] When a positioning portion 204 is provided on the chassis 20 and a buckle 105 is provided on the wire pressing plate 10, when the buckle 105 can move relative to the card slot 203 in the first direction to the limit position, the buckle 105 cooperates with the positioning portion 204 to limit the position of the wire pressing plate 10 relative to the chassis 20. When a positioning portion 204 is provided on the chassis 20 and a card slot 203 is provided on the wire pressing plate 10, when the buckle 105 can move relative to the card slot 203 in the first direction to the limit position, the card slot 203 cooperates with the positioning portion 204 to limit the position of the wire pressing plate 10 relative to the chassis 20, realizing the positioning of the wire pressing plate 10 relative to the chassis. This positioning method is simple and easy to operate, does not require screwing, and has high production efficiency.

[0095] Alternatively, a positioning portion 204 can also be provided on the wire pressing plate 10. When a positioning portion 204 is provided on the wire pressing plate 10 and a buckle 105 is provided on the chassis 20, when the buckle 105 can move relative to the card slot 203 in the first direction to the limit position, the buckle 105 cooperates with the positioning portion 204 to limit the position of the wire pressing plate 10 relative to the chassis 20. When a positioning portion 204 is provided on the wire pressing plate 10 and a card slot 203 is provided on the chassis 20, when the buckle 105 can move relative to the card slot 203 in the first direction to the limit position, the card slot 203 cooperates with the positioning portion 204 to limit the position of the wire pressing plate 10 relative to the chassis, realizing the positioning of the wire pressing plate 10 relative to the chassis 20. This positioning method is simple and easy to operate, does not require screwing, and has high production efficiency.

[0096] Among them, the number of the buckles 105 or the card slots 203 provided on the wire pressing plate 10 is one or more. When there are multiple ones, the multiple buckles 105 or card slots 203 are arranged opposite to each other in sequence along the length direction of the wire pressing plate 10. Among them, the number of the buckles 105 and the card slots 203 is equal and they correspond to each other one by one.

[0097] Optionally, at the limit position, the buckle 105 or the card slot 203 cooperates with the positioning portion 204 to limit the movement of the buckle 105 relative to the card slot 203 in the second direction, where the second direction is opposite to the first direction. As Figure 26 shown, a buckle is provided on the wire pressing plate, a positioning portion and a card slot are provided on the chassis, and the buckle is in the limit position.

[0098] Taking the chassis 20 having a positioning portion 204 and the wire pressing plate 10 having a buckle 105 as an example at the limit position, as Figure 24 shown, when the buckle 105 moves in the first direction to approach the positioning portion 204, the buckle 105 cooperates with the positioning portion 204 to be able to limit the movement of the buckle 105 relative to the card slot 203 in the second direction, that is, to be able to limit the movement of the buckle 105 in the direction away from the positioning portion 204, avoiding the separation of the buckle 105 from the positioning portion 204.

[0099] As Figure 26As shown, the first direction is from the card slot 203 to the positioning portion 204, and is also from the end of the card slot 203 away from the positioning portion 204 to the end close to the positioning portion 204.

[0100] Optionally, the card slot 203 extends along the length direction of the wire slot 31, and the buckle 105 moves relative to the card slot 203 along the length direction of the card slot 203; when the positioning portion 204 is provided on the chassis 20, the positioning portion 204 and the buckle 105 or the card slot 203 provided on the chassis 20 are arranged in sequence along the length direction of the card slot 203; when the positioning portion 204 is provided on the wire pressing plate 10, the positioning portion 204 and the buckle 105 or the card slot 203 provided on the wire pressing plate 10 are arranged in sequence along the length direction of the card slot 203.

[0101] The card slot extends along the length direction of the wire slot 31, and the buckle 105 moves relative to the card slot 203 along the length direction of the card slot 203. In this way, after the buckle 105 is inserted into the card slot 203, it moves relative to the card slot 203 along the length direction of the wire slot 31 to move to the limit position. That is, during the installation process of assembling the wire pressing plate 10 onto the chassis 20, after the buckle 105 is inserted into the card slot 203, the wire pressing plate 10 moves relative to the chassis 20 along the length direction of the wire slot 31, avoiding interference between the wire pressing plate 10 and the chassis 20 during the movement process.

[0102] For example, the positioning portion 204 and the card slot 203 are provided on the chassis 20, and the buckle 105 is provided on the wire pressing plate 10. The positioning portion 204 and the buckle 105 or the card slot 203 provided on the chassis 20 are arranged in sequence along the length direction of the card slot 203. When the buckle 105 is inserted into the card slot 203 and moves in the direction of the positioning portion 204, the buckle 105 moves along the length direction of the card slot 203. When it moves to the limit position, the buckle 105 cooperates with the positioning portion 204, so that the wire pressing plate 10 is fixed on the chassis, which is convenient for installation, improves the installation efficiency, and reduces the cost.

[0103] Another example is that the card slot 203 and the positioning portion 204 are provided on the wire pressing plate 10, and the buckle 105 is provided on the chassis 20. The positioning portion 204 and the buckle 105 or the card slot 203 provided on the wire pressing plate 10 are arranged in sequence along the length direction of the card slot 203. When the buckle 105 is inserted into the card slot 203 and moves in the direction of the positioning portion 204, the buckle 105 moves along the length direction of the card slot 203. When it moves to the limit position, the buckle 105 cooperates with the positioning portion 204, so that the wire pressing plate 10 is fixed on the chassis 20, which is convenient for installation, improves the installation efficiency, and reduces the cost.

[0104] Optionally, as Figure 26 shown, the positioning portion 204 includes a positioning protrusion 33. At the limit position, the buckle 105 abuts against the positioning protrusion 33 to limit the movement of the buckle 105 relative to the card slot 203 in the second direction.

[0105] As shown Figure 24 in the figure, the positioning protrusion 33 includes a first positioning section 331 and a second positioning section 332.

[0106] The first positioning section 331 and the second positioning section 332 are arranged in sequence along the first direction. The first positioning section 331 and the second positioning section 332 are connected, and a first bending 208 is formed at the connection. The positioning protrusion 33 may have a triangular structure.

[0107] As shown Figure 24 in the figure, the structure at the first bending 208 is a bulging structure upward, or it may also be a sunken structure downward.

[0108] Wherein, in the limiting position, the buckle 105 abuts against the first bending 208 and / or abuts against the second positioning section 332.

[0109] The positioning part 204 includes the positioning protrusion 33. In the limiting position, the buckle abuts against the first bending 208 and / or abuts against the second positioning section 332, which can limit the movement of the buckle 105 relative to the card slot 203 in the second direction, prevent the buckle 105 from separating from the positioning part 204, and can also limit the movement of the buckle 105 in the direction towards the wire slot 31, making the clamping connection between the wire pressing plate 10 and the chassis 20 more fixed.

[0110] Optionally, as shown Figure 24 in the figure, along the first direction, the second positioning section 332 is inclined towards the direction away from the buckle 105.

[0111] The buckle 105 includes a first clamping part 1051. In the limiting position, the first clamping part 1051 abuts against the second positioning section 332, and the inclination direction is the same as that of the second positioning section 332.

[0112] The first clamping part 1051 is arranged on the surface of the buckle 105 facing the second positioning section 332. The inclination directions of the second positioning section 332 and the first clamping part 1051 are such that in the limiting position, the second positioning section 332 can limit the movement of the buckle 105 in the second direction. Moreover, the first clamping part 1052 has the same inclination direction as the second positioning section 332, so that the contact area between the first clamping part 1051 and the second positioning section 332 is increased. The surfaces of the first clamping part 1051 for abutting against the second positioning section 332 and the second positioning section 332 for abutting against the first clamping part 1051 have the same shape, so as to further increase the contact area between the first clamping part 1051 and the second positioning section 332. For example, both are planar, increasing the mutual acting force along between the first clamping part 1051 and the second positioning section 332, making the abutting between the two more firm.

[0113] Optionally, as shown Figure 24As shown, the buckle 105 further includes a guiding portion 1052. The first engaging portion 1051 is connected to the guiding portion 1052 and arranged in sequence along the first direction. Along the first direction, the guiding portion 1052 is inclined away from the positioning protrusion 33.

[0114] Wherein, the inclination direction of the first positioning section 331 is the same as that of the guiding portion 1052.

[0115] The guiding portion 1052 is connected to the first engaging portion 1051 and has a different inclination direction, so that a fold angle is formed at the connection between the guiding portion 1052 and the first engaging portion 1051.

[0116] The first positioning section 331 has the same inclination direction as the guiding portion 1052. The first positioning section 331 cooperates with the guiding portion 1052, which is beneficial for the guiding portion 1052 to move along the first direction to the limiting position, enabling the guiding portion 1052 to more smoothly cross the first positioning section 331 during the sliding process, playing a guiding role, so that the buckle 105 can smoothly reach the limiting position.

[0117] Optionally, the buckle 105 further includes a second engaging portion 1054. Along the first direction, the second engaging portion 1054 and the first engaging portion 1051 are arranged in sequence and the second engaging portion 1054 is inclined away from the positioning protrusion 33, so that a second bending 1055 is formed at the connection between the second engaging portion 1054 and the first engaging portion 1051, and the second bending 1055 corresponds to the first bending 208.

[0118] The second engaging portion 1054 is inclined away from the positioning protrusion 33, that is, the inclination direction of the second engaging portion 1054 is the same as that of the first positioning section 331, and the second bending 1055 corresponds to the first bending 208, and the second engaging portion 1054 corresponds to the first positioning section 331. Thus, when the buckle 105 moves to the limiting position, the first engaging portion 1051 abuts against the second positioning section 332, the second engaging portion 1054 abuts against the first positioning section 331, and the second bending 1055 corresponds to the first bending 208. In this way, the second engaging portion 1054 can limit the buckle 105 from continuing to move in the first direction after reaching the limiting position.

[0119] Optionally, as Figure 24 shown, the side wall of the card slot 203 includes a first side wall 2031 and a second side wall 2032. The second side wall 2032 is arranged opposite to the first side wall 2031, and the first side wall 2031 and the second side wall 2032 are arranged in sequence along the first direction; wherein, at the limiting position, the buckle 105 abuts against the second side wall 2032.

[0120] The card slot 203 is in a long strip shape. One end of the card slot 203 close to the positioning portion 204 in the length direction of the card slot 203 is the second side wall 2032, and the end far from the positioning portion 204 is the first side wall 2031. The first side wall 2031 and the second side wall 2032 are arranged oppositely, and the first side wall 2031 and the second side wall 2032 are arranged in sequence along the first direction. When the buckle 105 is inserted into the card slot 203, the first side wall 2031 and the second side wall 2032 are arranged on opposite sides of the buckle 105 along the length direction of the card slot 203.

[0121] When installing the wire pressing plate 10, the buckle 105 is inserted into the card slot 203. When the buckle 105 moves along the length direction of the card slot 203 in the first direction, the first side wall 2032 of the buckle 105 away from the card slot 203 approaches the second side wall 2032 of the card slot 203. When the buckle 105 moves to the limit position, the buckle 105 abuts against the second side wall 2032 of the card slot 203, and the second side wall 2032 restricts the buckle 105 from continuing to move in the first direction at the limit position, thereby playing a role in limiting the buckle 105.

[0122] Optionally, as Figure 24 shown, an elastic groove 207 is provided at the connection between the positioning portion 204 and the chassis 20 or the wire pressing plate 10 where it is located.

[0123] When the positioning portion 204 is provided on the chassis 20, an elastic groove is provided at the connection between the positioning portion 204 and the chassis 20. When the positioning portion 204 is provided on the wire pressing plate 10, an elastic groove is provided at the connection between the positioning portion 204 and the wire pressing plate 10.

[0124] Providing an elastic groove at the connection between the positioning portion 204 and the chassis 20 or the wire pressing plate 10 where it is located can enhance the elasticity and deformation ability of the limiting convex portion, which can make it easier for the buckle 105 to move to the limit position in the first direction, reduce the installation difficulty, and improve the installation efficiency of the wire pressing plate 10.

[0125] Taking the buckle 105 provided on the wire pressing plate 10 as an example, the buckle 105 can be bent from the material of the wire pressing plate 10 itself, and an opening is provided at the connection between the buckle and the wire pressing plate to increase the elasticity of the buckle. The positioning portion 204 can be formed by pressing the material on the chassis 20 or the wire pressing plate 10 where it is located.

[0126] Embodiment Three:

[0127] On the basis of Embodiment One, as Figures 8 to 16 shown, one of the chassis 20 and the wire pressing plate 10 is provided with a limiting protrusion 2044, and the other of the chassis 20 and the wire pressing plate 10 is provided with a limiting hole 205.

[0128] Among them, as Figure 13 and Figure 15As shown, the limiting hole 205 includes a first hole segment 2051 and a second hole segment 2052 that are connected. The opening size of the first hole segment 2051 is larger than the opening size of the second hole segment 2052. The limiting protrusion 2044 is limited to the second hole segment 2052, and the opening size of the first hole segment 2051 is larger than or equal to the size of the limiting protrusion 2044, so that the limiting protrusion 2044 can slide into the first hole segment 2051 and can escape from the first hole segment 2051 under the action of external force.

[0129] In the case where the chassis 20 is provided with a limiting hole 205, the first connection matching portion 201 includes the limiting hole 205, and the first connection portion 103 includes a limiting protrusion 2044 provided on the wire pressing plate 10. In the case where the wire pressing plate 10 is provided with a limiting protrusion 2044, the first connection matching portion 201 includes the limiting hole 205 provided on the chassis 20, and the first connection portion 103 includes a limiting protrusion 2044 provided on the wire pressing plate 10.

[0130] One of the chassis 20 and the wire pressing plate 10 is provided with a limiting hole 205, and the other of the chassis 20 and the wire pressing plate 10 is provided with a limiting protrusion 2044. The limiting hole 205 and the limiting protrusion 2044 cooperate to achieve the positioning of the wire pressing plate 10 relative to the chassis 20.

[0131] In the case where the limiting hole 205 is provided on the chassis 10 and the limiting protrusion is provided on the wire pressing plate 10, after the limiting protrusion 2044 is inserted into the second hole section 5220, it is limited to the second hole section 2052. Through the cooperation between the limiting protrusion 2044 and the second hole section 2052, the position of the wire pressing plate 10 relative to the chassis 20 can be limited. In the case where the limiting protrusion 2044 is provided on the chassis 20 and the limiting hole 205 is provided on the wire pressing plate 10, after the limiting protrusion 2044 is inserted into the second hole section 2052, it is limited to the second hole section 2052. Through the cooperation between the limiting protrusion 2044 and the second hole section 2052, the position of the wire pressing plate 10 relative to the chassis 20 can be limited.

[0132] Through the cooperation between the limiting protrusion 2044 and the second hole section 2052, the position of the wire pressing plate 10 relative to the chassis 20 can be limited, so that the wire pressing plate 10 can be positioned or fixed relative to the chassis 20. This positioning method is simple and easy to operate, does not require screwing, and has high production efficiency.

[0133] When disassembling the wire pressing plate 10, an external force is applied to the limiting protrusion 2044. Under the action of the external force, the limiting protrusion 2044 slides from the second hole section 2052 into the first hole section 2051. Since the opening size of the first hole section 2051 is greater than or equal to the size of the limiting protrusion 2044, the limiting protrusion 2044 can be disengaged from the first hole section 2051, thereby releasing the limitation between the wire pressing plate 10 and the chassis 20 and realizing the disassembly of the wire pressing plate 10. Moreover, compared with the screw connection between the wire pressing plate 10 and the chassis 20, there is no problem of the screw slipping due to multiple disassembly in this application. Therefore, the wire pressing plate 10 can be disassembled repeatedly, improving production efficiency, reducing costs, and increasing the speed of after-sales maintenance.

[0134] Optionally, as Figure 13 shown, the opening size of the first hole section 2051 is greater than the opening size of the second hole section 2052.

[0135] The opening size of the second hole section 2052 is smaller than the size of the limiting protrusion 2044, thereby realizing the limitation of the limiting protrusion 2044. The opening size in the first hole section 2051 is greater than or equal to the size of the limiting protrusion 2044, thereby realizing that the limiting protrusion 2044 can be disengaged from the first hole section 2051.

[0136] The limiting protrusion 2044 is a three-dimensional structure with multiple dimensions. The limiting protrusion 2044 has a dimension in the first direction. The second hole section 2052 realizes the limitation of the limiting protrusion 2044 by limiting the dimension in the first direction. Then, in the statement that "the opening size of the first hole section 2051 is greater than the opening size of the second hole section 2052", the opening size refers to the dimension in the first direction, and the statement that "the opening size of the first hole section 2051 is greater than or equal to the size of the limiting protrusion 2044" means that "the dimension in the first direction of the first hole section 2051 is greater than or equal to the dimension in the first direction of the limiting protrusion 2044".

[0137] For example, the dimension in the first direction of the limiting protrusion 2044 is the dimension in the length direction. When the limiting protrusion 2044 is located in the second hole section 2052, it is because the dimension in the length direction of the limiting protrusion 2044 is greater than the dimension in the length direction of the second hole section 2052, resulting in the inability of the limiting protrusion 44 (should be 2044) to be disengaged from the second hole section 2052, that is, the second hole section 2052 realizes the limitation of the limiting protrusion 2044. Then, the length dimension of the first hole section 2051 is greater than the length dimension of the second hole section 2052, and the length dimension of the first hole section 2052 is greater than the length dimension of the limiting protrusion 2044.

[0138] Optionally, the limiting protrusion 2044 includes a first protrusion section 106 and a second protrusion section 107. The first protrusion section 106 is disposed within the second hole section 2052; the second protrusion section 107 passes through the second hole section 2052 and is connected to the first protrusion section 106. The size of the second protrusion section 107 is greater than the opening size of the second hole section 2052 to prevent the second protrusion section 107 from disengaging from the second hole section 2052, and the size of the second protrusion section 107 is less than or equal to the opening size of the first hole section 2051 so that the second protrusion section 107 can slide into the first hole section 2051 under an external force and can disengage from the first hole section 2051.

[0139] Along the direction in which the limiting protrusion 2044 is inserted into the second hole section 2052, the first protrusion section 106 and the second protrusion section 107 are arranged in sequence. When assembling the wire pressing plate 10 and the chassis 20, the limiting protrusion 2044 is inserted into the limiting hole 205, and the second protrusion section 107 passes through the first hole section 2051. At this time, the first protrusion section 106 and the second hole section 2052 are misaligned. Since the wire pressing plate 10 itself has a certain elasticity, for example, the wire pressing plate 10 is a sheet metal part to meet the elastic requirements of the wire pressing plate 10, under the elastic action of the wire pressing plate 10, the first protrusion section 106 corresponds to the second hole section 2052, and the first protrusion section 106 is inserted into the second hole section 2052 to realize the limitation of the first protrusion section 106 by the second hole section 2052.

[0140] The opening size of the second protrusion section 107 is less than or equal to the opening size of the first hole section 2051, so that the second protrusion section 107 can smoothly pass through the first hole section 2051 to realize the disengagement or insertion of the second protrusion section 107 from the first hole section 2051. The opening size of the second hole section 2052 is less than the size of the second protrusion section 107, and the second hole section 2052 can realize the limitation of the second protrusion section 107.

[0141] When disassembling the wire pressing plate 10, only an external force needs to be applied to the second protrusion section 107. Under the action of the external force, the second protrusion section 107 slides from the second hole section 2052 into the first hole section 2051, and the second protrusion section 107 can easily disengage from the first hole section 2051; and the wire pressing plate 10 can be disassembled repeatedly, reducing costs and improving production efficiency.

[0142] Optionally, the size of the first protrusion section 106 is less than or equal to the opening size of the second hole section 2052, making it more convenient for the wire pressing plate 10 to be assembled on the chassis 20 with the first protrusion section 106 inserted into the second hole section 2052.

[0143] The first protrusion segment 106 and the second protrusion segment 107 are both three-dimensional structures with multiple sizes. The second protrusion segment 107 has a size in the first direction. The second hole segment 2052 limits the size in the first direction to limit the second protrusion segment 107, thereby preventing the second protrusion segment 107 from coming out of the second hole segment 2052. Then, "the size of the second protrusion segment 107 is greater than the opening size of the second hole segment 2052" means "the size of the second protrusion segment 107 in the first direction is greater than the opening size of the second hole segment 107 in the first direction", "the size of the second protrusion segment 107 is less than or equal to the opening size of the first hole segment 106" means "the size of the second protrusion segment 107 in the first direction is less than or equal to the opening size of the first hole segment 5051 in the first direction", and "the size of the first protrusion segment 106 is less than or equal to the opening size of the second hole segment 2052" means "the size of the first protrusion segment 106 in the first direction is less than or equal to the opening size of the second hole segment 2052 in the first direction".

[0144] The first dimension is the length direction ( Figure 10 The size of the center (left and right direction).

[0145] Alternatively, if Figure 10 As shown, the second protruding section 107 includes a first limiting section 1071, a second limiting section 1072 and a third limiting section 1073. The second limiting section 1072 is arranged at one side of the first limiting section 1071; the third limiting section 1073 is connected to the first limiting section 1071 and arranged opposite to the second limiting section 1072; wherein, the orthographic projection of the first limiting section 1071 on the chassis 20 or the wire pressing plate 10 where the limiting hole 205 is located is located inside the second hole section 2052, and the orthographic projections of the second limiting section 1072 and the third limiting section 1073 on the chassis 10 or the wire pressing plate 10 where the limiting hole 205 is located are located outside the second hole section 2052.

[0146] The second protruding section 107 includes a first limiting section 1071, a second limiting section 1072, and a third limiting section 1073 sequentially arranged along the first direction. When the wire pressing plate 10 is assembled in place on the chassis 20, the first limiting section 1071 is arranged corresponding to the second hole section 2052, and the second limiting section 1072 and the third limiting section 1073 are staggered with the second hole section 2052, so that the second limiting section 1072 and the third limiting section 1073 cannot escape from the second hole section 2052, so that the second hole section 1052 can limit the second protruding section 107.

[0147] Alternatively, if Figure 13As shown, the first hole section 2051 includes a second escape section 2054, a first escape section 2053, and a third escape section 2055 arranged in sequence. When the limit projection 2044 enters the first hole section 2051, the first limit section 1071 corresponds to the first escape section 2053, the second limit section 1072 corresponds to the second escape section 2054, and the third limit section 1073 corresponds to the third escape section 2055.

[0148] When installing the wire pressing plate 10, the second convex section 107 passes through the first hole section 2051. Specifically, the first limit section 1071 corresponds to the first escape section 2053, the second limit section 1072 corresponds to the second escape section 2054, the first limit section 1071 is inserted into the first escape section 2053, the second limit section 1072 is inserted into the second escape section 2054, and the third limit section 1073 is inserted into the third escape section 2055, so that the second convex section 107 is inserted into the first hole section 2051; when disassembling the wire pressing plate 10, under the action of an external force, the limit projection 2044 slides from the second hole section 2052 into the first hole section 2051, disengaging the first limit section 1071 from the first escape section 2053, the second limit section 1072 from the second escape section 2054, and the third limit section 1073 from the third escape section 2055, so that the limit projection 2044 can escape from the limit hole 205.

[0149] Optionally, as Figure 10 shown, the limit projection 2044 further includes a guiding convex section 108. The first convex section 106, the second convex section 107, and the guiding convex section 108 are arranged in sequence. The guiding convex section 108 is provided on the side of the second convex section 2042 facing the first hole section 2051 and forms an obtuse angle at the connection with the second convex section 107.

[0150] The guiding convex section 108 is connected to the second convex section 107 to form an obtuse angle, and the guiding convex section 108 is provided on the side of the second convex section 107 facing the first hole section 2051. The first hole section 2051 includes a first side 2056 and a second side 2057, and the first side 2056 and the second side 2057 are arranged in sequence along the direction from the first hole section 2051 to the second hole section 2052. In this way, when assembling the wire pressing plate 10, the guiding convex section 108 first slides into the first hole section 2051 and abuts against the second side 2057 during the sliding process, playing a guiding role, guiding the second convex section 107 to be inserted into the first hole section 2051, and driving the second convex section 107 to deform in a direction away from the second hole section 2052 during the guiding process. Thus, after the second convex section 107 enters and exits the first hole section 2051, the restoring force of the limit projection 2044 due to deformation will guide the limit projection 2044 to move towards the first hole section 2051, so that the first convex section 106 slides into the second hole section 2052.

[0151] Optionally, as Figure 11 shown, the wire pressing plate 10 or the chassis 20 provided with the limit protrusion 2044 includes: a main body 109, the main body 109 is provided with a notch 112, and the limit protrusion 2044 is connected to the side wall of the notch 112.

[0152] This can enhance the deformation ability of the limit protrusion 2044. Thus, when installing the wire pressing plate 10, the second protrusion section 107 can pass through the first hole section 2051 and move toward the second hole section 2052 to abut against the second hole section 2052, so that the wire pressing plate 10 is fixed to the chassis 20; when disassembling the wire pressing plate 10, under the action of an external force, the second protrusion section 107 can slide into the first hole section 2051 again, so that the second protrusion section 107 disengages from the first hole section 2051, and the wire pressing plate 10 can be disassembled.

[0153] Optionally, the chassis assembly of the air conditioner further includes a clamping portion 111 and a clamping and mating portion 206. The clamping portion 111 is provided on one of the wire pressing plate 10 and the chassis 20; the clamping and mating portion 206 is provided on the other of the wire pressing plate 10 and the chassis 20 and is clamped with the clamping portion 111.

[0154] The clamping and mating portion 206 is provided on the chassis 20, and the clamping portion 111 is provided on the wire pressing plate 10, or the clamping portion 111 is provided on the chassis 20, and the clamping and mating portion 206 is provided on the wire pressing plate 10. One of the clamping portion 111 and the clamping and mating portion 206 is a buckle, and the other is a slot. The buckle is clamped with the slot, which can limit the wire pressing plate 10, prevent the wire pressing plate 10 from shifting or being misaligned during installation, make the connection between the wire pressing plate 10 and the chassis 20 more stable, and can also enhance the connection strength between the wire pressing plate 10 and the chassis 20.

[0155] Wherein, one or more clamping portions 111 and clamping and mating portions 206 can be provided, and the number of the clamping portions 111 and the clamping and mating portions 206 is equal and they correspond to each other one by one.

[0156] The limit protrusion 2044 and the clamping portion 111 are arranged on opposite sides in the width direction of the wire routing groove 31.

[0157] Optionally, along the direction in which the clamping portion 111 and the clamping and mating portion 206 are clamped, the second hole section 2052 and the first hole section 2051 are arranged in sequence.

[0158] When disassembling the wire pressing plate 10, an external force is applied to the second protrusion section 107, so that the second protrusion section 107 slides into the first hole section 2051 and disengages from the first hole section 2051. The direction of the external force is the direction in which the clamping portion 111 and the clamping and mating portion 206 are clamped, that is, the direction in which their connection is more reliable, so as to avoid the disengagement of the clamping portion 111 and the clamping and mating portion 206 due to the external force.

[0159] It can be understood that in the second embodiment, the chassis assembly may also include a clamping portion 111 and a clamping and mating portion 206. The clamping portion 111 is provided on one of the wire pressing plate 10 and the chassis 20; the clamping and mating portion 206 is provided on the other of the wire pressing plate 10 and the chassis 20 and is clamped with the clamping portion 111.
