[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiment is only a connection structure embodiment of the utility model, not all embodiments.

[0050] In the related art, the first end of the functional module is fixed to the chassis, and the second end is connected to the bracket. When the heat exchanger needs to be disassembled for inspection, it is easy to directly disassemble the bracket supporting the heat exchanger without considering the functional module, that is, the second end of the functional module will move with the bracket, and because the first end of the functional module is still fixedly connected to the chassis, the functional module will be pulled by the moving bracket and the fixed chassis, resulting in damage.

[0051] In view of this, the first embodiment of the present utility model provides an indoor unit 10, which can ensure the structural integrity of the functional module 400 during maintenance and improve the safety of the product. Figures 1 to 8 The indoor unit 10 of the embodiment of the present application is introduced. Specifically, the indoor unit 10 includes a chassis 100, a heat exchanger 200, a bracket 300 and a functional module 400.

A heat exchanger 200 can be arranged on the chassis 100, and the heat exchanger 200 can exchange heat with the external air. The heat exchanger 200 is connected to the chassis 100. The heat exchanger 200 includes a coil assembly, and the coil assembly is provided with a plurality of coils 210. The coil assembly can conduct refrigerant. The refrigerant can circulate inside the coil assembly and adaptively evaporate or condense to cool or heat the air. The specific setting of the heat exchanger 200 can refer to the relevant known technology.

[0053] The bracket 300 is used to support the end side of the heat exchanger 200. Figure 1 In some embodiments, the bracket 300 can support the left side of the heat exchanger 200. In other embodiments, the bracket 300 can also support the right side of the heat exchanger 200. Some embodiments of the present application are described by taking the bracket 300 supporting the left side of the heat exchanger 200 as an example. Specifically, refer to Figure 2 and Figure 4, the bracket 300 may be provided with a plurality of installation holes 330 arranged at intervals. The plurality of coils 210 of the heat exchanger 200 may be provided with the installation holes 330 one by one. In addition, the bracket 300 may be detachably connected to the chassis 100. To facilitate the description and understanding of the specific disassembly process of the bracket 300, a first direction X is defined, and the bracket 300 is at least partially capable of being detached from the chassis 100 along the first direction X. It should be noted that in some embodiments, the first direction X may be a single direction, that is, the bracket 300 may move in a single direction to be detached from the chassis 100. In other embodiments, the first direction X may also be a collection of multiple directions, that is, the bracket 300 may move in one direction and then in other directions to be detached from the chassis 100. The specific separation setting of the bracket 300 and the chassis 100 may depend on the actual structures of the two. Figure 1 With the center as a reference, the first direction X may point to the front-rear direction, and the bracket 300 may be removed from the chassis 100 from bottom to top, and then separated from the chassis 100 from front to back.

[0054] Functional module 400 is used to realize corresponding functions. Specifically, functional module 400 may include at least one of negative ion module, ozone generating module, activated carbon module or ultraviolet lamp module. It should be noted that in some embodiments, functional module 400 may include any one of negative ion module, ozone generating module, activated carbon module or ultraviolet lamp module. In other embodiments, functional module 400 may also include any multiple modules of negative ion module, ozone generating module, activated carbon module or ultraviolet lamp module. It is understood that when functional module 400 includes multiple modules, each module can be connected as one. The specific setting of functional module 400 can be determined according to actual conditions. Some embodiments of the present application are described by taking functional module 400 including negative ion module as an example.

[0055] The functional module 400 includes a first portion 410 and a second portion 420, and the first portion 410 and the second portion 420 are connected to each other. Figure 1 With reference to the orientation in the figure, the first part 410 may be the part of the functional module 400 located on the right side, and the second part 420 may be the part of the functional module 400 located on the left side. It should be noted that the first part 410 is detachably connected to the chassis 100. The second part 420 is connected to the bracket 300. Specifically, the second part 420 may be detachably connected to the bracket 300, or may be fixedly connected to the bracket 300. Some embodiments of the present application are described by taking the detachable connection between the second part 420 and the bracket 300 as an example. In addition, the chassis 100 is also provided with a limiting structure 110, which may cooperate with the second part 420 of the functional module 400 to limit the second part 420 from detaching from the chassis 100 along the first direction X. It should be noted that the limiting structure 110 may be detachably connected to the second part 420.

[0056] In the technical solution of the utility model, the indoor unit 10 includes a chassis 100, a heat exchanger 200, a bracket 300 and a functional module 400. The heat exchanger 200 is connected to the chassis 100. The bracket 300 supports the end side of the heat exchanger 200 and is connected to the chassis 100. The bracket 300 can be at least partially disassembled from the chassis 100 along the first direction X. The functional module 400 includes a first part 410 and a second part 420 connected to each other. The first part 410 is detachably connected to the chassis 100, and the second part 420 is connected to the bracket 300. In the prior art, when the heat exchanger needs to be disassembled and repaired, it is easy to directly disassemble the bracket supporting the heat exchanger without considering the functional module, that is, the functional module will be pulled by the moving bracket and the fixed chassis and damaged. In this solution, the chassis 100 is provided with a limiting structure 110, and the limiting structure 110 cooperates with the second part 420 to limit the second part 420 from being separated from the chassis 100 along the first direction X. Since the second part 420 is connected to the bracket 300, the bracket 300 can be limited to be separated from the chassis 100 along the first direction X, thereby preventing the bracket 300 from being normally removed before the functional module 400. Moreover, even if the bracket 300 is forcibly disassembled without considering the functional module 400, since the first part 410 and the second part 420 of the functional module 400 are both connected to the chassis 100, compared with the solution of the prior art in which only one end of the functional module is connected to the chassis, this solution can also effectively suppress the damage of the functional module 400. Therefore, this solution can effectively ensure the structural integrity of the functional module 400 during after-sales maintenance and improve the safety of the product.

[0057] The following describes the specific connection arrangement of the limiting structure 110 and the second part 420 in some embodiments. Specifically, the second part 420 of the functional module 400 includes a first connection structure 421. Figures 2 to 5 as well as Figure 7 In some embodiments, the first connection structure 421 can be engaged with the limiting structure 110, thereby limiting the first connection structure 421 from being separated from the chassis 100 along the first direction X. This solution can ensure the stability of the assembly connection between the first connection structure 421 and the limiting structure 110. Figure 6 In other embodiments, the first connection structure 421 can be spaced apart from the limiting structure 110 along the first direction X, that is, the limiting structure 110 can be provided with a stopper 112 to limit the first connection structure 421 from detaching from the chassis 100 along the first direction X. The limiting structure 110 of this solution is easy to process and shape.

[0058] Reference Figures 2 to 5, the specific connection settings of the second part 420 with the chassis 100 and the bracket 300 of some embodiments are introduced below. In some embodiments, the second part 420 includes a first connection structure 421 and a second connection structure 422. The specific structures of the first connection structure 421 and the second connection structure 422 can be the same or different. Some embodiments of the present application are described by taking the different structures of the two as an example. The second connection structure 422 can be connected to the bracket 300, and the first connection structure 421 can cooperate with the limiting structure 110 of the chassis 100. The first connection structure 421 and the second connection structure 422 of this solution respectively connect the bracket 300 and the limiting structure 110, which can effectively improve the stability of the connection between the second part 420 and the chassis 100 and the bracket 300.

The second direction Y can be perpendicular to the first direction X, or it can be at other non-perpendicular inclination angles. Some embodiments of the present application are described by taking the second direction Y being perpendicular to the first direction X as an example. Specifically, the first connection structure 421 can be detached from the chassis 100 along the second direction Y, and the second connection structure 422 can be detached from the bracket 300 along the second direction Y, that is, the first connection structure 421 and the second connection structure 422 can be assembled and disassembled along the same direction. Compared with the solution in which the first connection structure 421 and the second connection structure 422 are assembled and disassembled along different directions respectively, this solution can improve the assembly and disassembly efficiency of the first connection structure 421 and the second connection structure 422.

Some embodiments of the present application are described by taking the second connection structure 422 being provided in both the first shell 430 and the second shell 440 as an example. This solution can ensure the stability of the assembly connection between the functional module 400, the bracket 300 and the limiting structure 110, and facilitate the demolding of the limiting structure 110.

[0069] Reference Figure 7 , the specific structure of the first protrusion 4211 is introduced below. First, the specific setting of the functional module 400 is introduced. The functional module 400 includes a first shell 430 and a second shell 440. It can be understood that the structures of the first shell 430 and the second shell 440 can be the same or different. Some embodiments of the present application are described by taking the different structures of the first shell 430 and the second shell 440 as an example. It should be noted that the second shell 440 can be arranged on the side of the first shell 430 away from the chassis 100, so as to Figure 7 With reference to the orientation in FIG. 4 , the second housing 440 may be disposed on the upper side of the first housing 430. The first housing 430 is provided with a first connection portion 431, and the second housing 440 is provided with a second connection portion 441. The structure of the first connection portion 431 may be different from that of the second connection portion 441, and the first connection portion 431 may be detachably connected to the second connection portion 441, and together define a first protrusion 4211. In other embodiments, the first protrusion 4211 may also be disposed separately on the first housing 430. Some embodiments of the present application are described by taking the example that the first protrusion 4211 is disposed separately on the first housing 430.

[0070] Reference Figure 7, the specific structure of the second protrusion 4221 is described below. In some embodiments, the first connection portion 431 of the first shell 430 can be detachably connected to the second connection portion 441 of the second shell 440, and together define the second protrusion 4221. In other embodiments, the second protrusion 4221 can also be separately provided on the first shell 430 or the second shell 440. Some embodiments of the present application are described by taking the first connection portion 431 and the second connection portion 441 together forming the second protrusion 4221 as an example. This solution can ensure the structural strength of the second protrusion 4221, thereby improving the stability of the connection between the functional module 400 and the bracket 300. Specifically, the first connection portion 431 may include a groove, and the second connection portion 441 may include a flange. The flange of the second connection portion 441 can penetrate the groove of the first connection portion 431 to jointly form the first protrusion 4211. The specific setting of the first protrusion 4211 can be determined according to actual conditions.

[0071] Reference Figures 3 to 5 , the relative arrangement positions of the first part 410 and the second part 420 of the functional module 400 are described below. In some embodiments, the second part 420 can be arranged at one end of the functional module 400 facing the bracket 300, and the first part 410 can be arranged at one end of the functional module 400 facing away from the second part 420. Figure 1 As a reference, the first part 410 can be located at the right end of the functional module 400, and the second part 420 can be located at the left end of the functional module 400. In this solution, the first part 410 and the second part 420 are located at opposite ends of the functional module 400, that is, a large distance can be created between the first part 410 and the second part 420. Compared with the solution in which the first part and the second part are arranged in close proximity, this solution can effectively improve the stability of the assembly connection between the functional module 400, the bracket 300 and the chassis 100.

[0072] Reference Figures 3 to 5 , the specific connection arrangement between the first part 410 of the functional module 400 and the chassis 100 is described below. In some embodiments, the first part 410 of the functional module 400 may be provided with a connection hole 411, and the chassis 100 may be provided with a base 120. The indoor unit 10 includes a fastener, and the fastener may pass through the connection hole 411 of the first part 410 and connect the base 120 of the chassis 100. It can be understood that the fastener may be a screw or a bolt, and the fastener may be threadedly connected to the base 120. This solution can ensure the stability of the assembly connection between the functional module 400 and the chassis 100.

[0073] In other embodiments, the first part 410 of the functional module 400 may be provided with a flange, the chassis 100 may be provided with a slot, and the flange of the first part 410 may penetrate and engage the slot of the chassis 100. In other embodiments, the chassis 100 may be provided with a flange, the first part 410 of the functional module 400 may be provided with a slot, and the flange of the chassis 100 may penetrate the slot of the first part 410. This solution can ensure the assembly efficiency of the first part 410 and the chassis 100.

[0074] Reference Figure 2 and Figure 5 , the specific connection arrangement of the bracket 300 and the chassis 100 is described below. In some embodiments, the chassis 100 may be provided with a slot 130, and the bracket 300 may be provided with a hook 320. The hook 320 of the bracket 300 at least partially penetrates the slot 130 of the chassis 100, and its specific penetration depth can be determined according to actual conditions. In other embodiments, the chassis 100 may be provided with a hook 320, the bracket 300 may be provided with a slot 130, and the hook 320 of the chassis 100 at least partially penetrates the slot 130 of the bracket 300. In other embodiments, the chassis 100 may be provided with a hook 320 and a slot 130 at the same time, and the bracket 300 may be provided with a slot 130 and a hook 320 at the same time, and each hook 320 is correspondingly penetrated by each slot 130. In this solution, the hook 320 penetrates the slot 130, that is, it can limit the bracket 300 from detaching from the chassis 100 along the first direction X. Compared with the solution in which the bracket is connected to the chassis only through the functional module, this solution can effectively improve the stability of the assembly connection of the bracket 300.

[0075] The second embodiment of the utility model proposes an air conditioner, which includes the indoor unit 10 of the above embodiment and also includes an outdoor unit. In this solution, the chassis 100 is provided with a limiting structure 110, and the limiting structure 110 cooperates with the second part 420 to limit the second part 420 from being separated from the chassis 100 along the first direction X, and because the second part 420 is connected to the bracket 300, it can limit the bracket 300 from being separated from the chassis 100 along the first direction X, thereby making it impossible for the bracket 300 to be normally removed before the functional module 400. Moreover, even if the bracket 300 is forcibly disassembled without considering the functional module 400, because the first part 410 and the second part 420 of the functional module 400 are both connected to the chassis 100, compared with the solution of the prior art in which only one end of the functional module is connected to the chassis, this solution can also effectively suppress the damage of the functional module 400. Therefore, this solution can effectively ensure the structural integrity of the functional module 400 in after-sales maintenance and improve the safety of the product.
