[0047] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0048] Combination Figure 1-8 As shown, this disclosure provides a chassis assembly for an air conditioner.

[0049] The air conditioner includes an indoor unit, which comprises a chassis assembly, an electric heater 20, a fan 30, and a heat exchanger. The electric heater 20 is used to provide auxiliary heating to the air within the indoor unit's air duct. The fan 30 drives air into the air duct to exchange heat with the heat exchanger before exiting the air duct.

[0050] like Figure 1 As shown, the chassis assembly includes a chassis 10 and a pressure plate 40.

[0051] The electric heater 20 and the fan 30 are fixedly mounted on the chassis 10.

[0052] The pressure plate 40 is placed on the chassis 10 and together with the chassis 10, forms the first wiring groove 404 and the second wiring groove 406.

[0053] The electric heating wire 201 of the electric heater 20 is located in the first wiring trough 404 and is connected to the power supply through the first wiring trough 404; the motor wire 301 of the fan 30 is located in the second wiring trough 406 and is connected to the power supply through the second wiring trough 406.

[0054] Among them, the pressure plate 40 is an integrated structure.

[0055] The pressure plate 40 and the chassis 10 together define the first wiring groove 404 and the second wiring groove 406. The electric heating wire 201 is located in the first wiring groove 404, and the motor wire 301 of the fan 30 is located in the second wiring groove 406. No wire tie is required, which improves production efficiency.

[0056] The wire clamping plate 40 is a one-piece structure, meaning that one wire clamping plate 40 simultaneously fixes both the electric heating wire 201 and the motor wire 301, eliminating the need for separate wire clamping plates 40 for each wire, thus further improving the fixing efficiency of the electric heating wire 201 and the motor wire 301. Furthermore, in this application, the electric heating wire 201 and the motor wire 301 are fixed separately via the first wiring groove 404 and the second wiring groove 406, eliminating the need for multiple positioning posts as in related technologies, and simplifying the structure of the wire clamping plate 40.

[0057] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the pressure plate 40 includes a first support plate 403 and a second support plate 405.

[0058] The first support plate 403 is installed on the chassis 10 and together with the chassis 10 forms the first cable tray 404. The second support plate 405 is installed on the chassis 10 and together with the chassis 10 forms the second cable tray 406. The first support plate 403 and the second support plate 405 are connected and the connection point forms a bend.

[0059] The first support plate 403 and the second support plate 405 are connected to realize the entire pressure plate 40 as an integrated structure.

[0060] The connection between the first support plate 403 and the second support plate 405 is bent, so that the first wiring trough 404 and the second wiring plate do not overlap, thereby realizing the separate wiring of the motor wire 301 and the electric heating wire 201, improving the electrical safety of the indoor unit.

[0061] Optionally, such as Figure 1 As shown, the length of the first wiring groove 404 is different from the length of the second wiring groove 406.

[0062] For example, the length of the first support plate 403 is greater than the length of the second support plate 405, the first wiring groove 404 extends along the length direction of the first support plate 403, and the second wiring groove 406 extends along the length direction of the second support plate 405, so that the length of the first wiring groove 404 is greater than the length of the second wiring groove 406.

[0063] The fan 30 is located in the middle of the chassis 10, and the electric heater 20 is located between the outer edge of the chassis 10 and the fan 30.

[0064] Because the fan 30 and the electric heater 20 are installed at different positions on the chassis 10, the length of the first wiring channel 404 is different from the length of the second wiring channel 406, so that the length of the first wiring channel 404 can be adapted to the position of the electric heater 20, and the length of the second wiring channel 406 can be adapted to the position of the fan 30.

[0065] Optionally, the length of the first wiring groove 404 is the same as the length of the second wiring groove 406.

[0066] Adjust the position of the pressure plate 40 on the chassis 10 so that the distance between the pressure plate 40 and the electric heater 20 and the fan 30 is the same, then the length of the first wiring groove 404 and the length of the second wiring groove 406 are the same.

[0067] Optionally, such as Figure 1 As shown, the cross-sectional area of ​​the first wiring groove 404 is different from that of the second wiring groove 406.

[0068] The electric heating wire 201 and the motor wire 301 have different thicknesses. Therefore, the cross-sectional area of ​​the first wiring groove 404 is adapted to the size of the electric heating wire 201, and the cross-sectional area of ​​the second wiring groove 406 is adapted to the size of the motor wire 301. The cross-sectional area of ​​the first wiring groove 404 is smaller than the cross-sectional area of ​​the second wiring groove 406, so that the first wiring groove 404 can stably fix the electric heating wire 201, and the second wiring groove 406 can stably fix the motor wire 301.

[0069] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the pressure plate 40 also includes a junction plate 401.

[0070] The junction plate 401 is connected at the bend. The junction plate 401 covers the chassis 10 and together with the chassis 10, forms a junction cable tray 402. The junction cable tray 402 is connected to the first cable tray 404 and the second cable tray 406.

[0071] One end of the first support plate 403 is connected to the confluence plate 401, and the other end of the first support plate 403 extends toward the electric heater 20. One end of the second support plate 405 is connected to the confluence plate 401, and the other end of the second support plate 405 extends toward the fan 30.

[0072] Both the electric heating wire 201 and the motor wire 301 pass through the converging wiring trough 402. That is, part of the electric heating wire 201 is located in the converging wiring trough 402 and part is located in the first wiring trough 404. Part of the motor wire 301 is located in the converging wiring trough 402 and part is located in the second wiring trough 406.

[0073] The converging plate 401 connects the first support plate 403 and the second support plate 405, enabling the pressure plate 40 to form an integrated structure. On the other hand, the converging cable tray 402 allows the motor wire 301 and the electric heating wire 201 to converge together.

[0074] The confluence plate, the first support plate, and the second support plate are integrated into a single structure, making the entire pressure plate a single unit.

[0075] Optionally, such as Figure 1 and Figure 4 As shown, the pressure plate 40 and / or the chassis 10 are provided with an observation window 407, which is connected to the first wiring groove 404 and / or the second wiring groove 406.

[0076] The pressure plate 40 is provided with an observation window 407, which is a through hole penetrating the pressure plate 40. And / or, the chassis 10 is provided with an observation window 407, which is a through hole penetrating the chassis 10.

[0077] When the observation window 407 is connected to the first wiring trough 404, the observation window 407 is set to correspond to the first wiring trough 404. Through the observation window 407, it is possible to see whether the wire harness in the first wiring trough 404 is installed in place, preventing the first support plate 403 from pressing down on the wire harness due to the wire harness not being properly fixed in the first wiring trough 404. When the observation window 407 is connected to the second wiring trough 406, the observation window 407 is set to correspond to the second wiring trough 406. Through the observation window 407, it is possible to see whether the wire harness in the second wiring trough 406 is installed in place, preventing the second support plate 405 from pressing down on the wire harness due to the wire harness not being properly fixed in the second wiring trough 406.

[0078] The number of observation windows 407 can be one or more. When there are multiple observation windows 407, they are arranged sequentially along the length of the first wiring groove 404 or the second wiring groove 406 where the observation window 407 is located, to observe whether the wire harnesses at various points along the length of the first wiring groove 404 or the second wiring groove 406 where the observation window 407 is located are fixed in place. The shape and size of the observation window 407 can be flexibly set in practical applications.

[0079] like Figure 1 As shown, the observation window 407 is provided on the first support plate 403, and there are multiple observation windows 407 arranged sequentially along the length direction of the first support plate 403.

[0080] Optionally, the pressure plate 40 is detachably connected to the chassis 10.

[0081] This arrangement facilitates the installation and removal of the pressure plate 40 on the chassis 10, thereby improving the fixing efficiency of the motor wire 301 and the electric heating wire 201.

[0082] Optionally, such as Figures 5 to 8 As shown, one of the pressure plate 40 and the chassis 10 is provided with a buckle 408, and the other is provided with a slot 101. The buckle 408 is engaged with the slot 101.

[0083] The snap-fit ​​design is simple in structure, easy to assemble, and highly reliable.

[0084] Optionally, after the latch 408 is inserted into the slot 101, it moves relative to the slot 101 so that the latch 408 is engaged in place within the slot 101, along the direction of movement of the latch 408 relative to the slot 101 (e.g., Figure 7 As indicated by the middle arrow, the opening area of ​​the card slot 101 is reduced.

[0085] Along the moving direction of the latch 408 relative to the slot 101, the opening area of ​​the slot 101 decreases. That is, when the latch 408 is inserted into the slot 101, the opening area of ​​the slot 101 corresponding to the initial latching position of the latch 408 is larger. Then, the latch 408 moves from the initial latching position toward a position with a smaller opening area on the slot 101. When the latch 408 is fully engaged, the opening area of ​​the slot 101 corresponding to the engaged position of the latch 408 is smaller.

[0086] like Figure 7 As shown, the latch 408 is inserted into the slot 101 from the larger opening area. After insertion, the latch 408 moves towards the smaller opening area of ​​the slot 101, and finally locks into the smaller opening area of ​​the slot 101. Figure 8 As shown. On the one hand, the buckle 408 is inserted into the slot 101 from the part with a larger opening area, which increases the insertion space of the buckle 408, increases the fault tolerance of the slot 101 for the buckle 408, reduces the requirements for the insertion position of the buckle 408, and also reduces the requirements for the machining accuracy of the slot 101; on the other hand, the buckle 408 moves towards the part with a smaller opening area of ​​the slot 101. The more the buckle 408 moves, the tighter the buckle 408 is engaged in the slot 101. When the buckle 408 is engaged, it is located at the part with the smallest opening area of ​​the slot 101, so that the buckle 408 is firmly located in the slot 101.

[0087] like Figure 6 As shown, the card slot 101 is triangular or similar to a triangle. The slot walls of the card slot 101 include a first slot wall 102, a second slot wall 103, a third slot wall 104, and a fourth slot wall 105 connected in sequence.

[0088] The first groove wall 102 and the second groove wall 103 are arranged opposite to each other, with the length of the first groove wall 102 being greater than the length of the second groove wall 103. A third groove wall 104 connects one end of the first groove wall 102 and the second groove wall 103, and a fourth groove wall 105 connects the other end of the first groove wall 102 and the second groove wall 103. The latch 408 is inserted into the latch slot 101 from near the first groove wall 102, and then moves relative to the latch slot 101 toward the second groove wall 103, finally engaging with the second groove wall 103.

[0089] like Figure 7 As shown, the buckle 408 is provided with a guide edge 412 so that the buckle 408 is engaged with the slot 101.

[0090] After the latch 408 is inserted into the slot 101, the latch 408 moves relative to the slot 101 to the engaged position. Along the direction of movement of the latch 408 relative to the slot 101, the guide edge 412 is inclined in the direction away from the slot 101 to facilitate the movement of the latch 408 relative to the slot 101 to the engaged position.

[0091] The 408 buckle is formed by stamping.

[0092] The pressure plate 40 or the chassis 10 is stamped to form a buckle 408, and the buckle 408 is directly connected to the side wall of the stamped hole 411. This reduces the forming cost of the buckle 408, and the buckle 408 and the pressure plate 40 or chassis 10 on which the buckle 408 is located are an integral structure, thereby improving the strength of the buckle 408.

[0093] Both the chassis 10 and the pressure plate 40 are made of sheet metal, which can be bent into shape to form the buckle 408.

[0094] The number of clips 408 is one or more, for example, Figure 2 As shown, there are two clips 408, which are respectively located on the first support plate 403 and the second support plate 405.

[0095] The buckle 408 includes a first segment 409 and a second segment 410. A bend is formed at the connection between the first segment 409 and the second segment 410, and a guide edge 412 is located on the second segment 410. For example... Figure 7 As shown, when the buckle 408 is inserted into the slot 101, the first segment 409 is inserted into the slot 101, and the second segment 410 protrudes from the slot 101. The first segment 409 moves within the slot 101 in the direction where the opening of the slot 101 becomes smaller, as shown. Figure 8 As shown, when the buckle 408 is engaged, the first segment 409 moves to the smaller opening of the slot 101, and the second segment 410 abuts against the pressure plate 40 where the slot 101 is located or the chassis 10 where the slot 101 is located.

[0096] A screw connection structure is provided between the pressure plate 40 and the chassis 10.

[0097] The pressure plate 40 is provided with a first screw hole 413, and the chassis 10 is provided with a second screw hole. The screw passes through the first screw hole 413 and the second screw hole to realize the screw connection between the pressure plate 40 and the chassis 10.

[0098] Optionally, such as Figure 4 As shown, the edge of the pressure plate 40 on the side opposite to the chassis 10 is deburred or has a chamfer.

[0099] The edge of the pressure plate 40 on the side away from the chassis 10 is deburred or chamfered, so that the edge of the pressure plate 40 on the side away from the chassis 10 forms a flattening structure 414, which prevents the edge of the pressure plate 40 on the side away from the chassis 10 from wearing the electric heating wire 201 or the motor wire 301.

[0100] A second aspect of this utility model provides an air conditioner, including an indoor unit, which includes a chassis assembly as described in any of the above embodiments, an electric heater 20, and a fan 30.

[0101] The electric heating wire 201 of the electric heater 20 is located in the first wiring trough 404; the motor wire 301 of the fan 30 is located in the second wiring trough 406.

[0102] The air conditioner provided in the second aspect of this utility model includes a chassis assembly as described in any of the above embodiments, and therefore has all the beneficial effects of the chassis assembly as described in any of the above embodiments, which will not be repeated here.

[0103] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them.
