[0009] In one embodiment, the indoor unit further includes a mounting section disposed on the top of the fan assembly, the mounting section being used to mount an electrical control box, and the mounting section abutting against the top of the heat exchanger.

[0010] In one embodiment, the indoor unit further includes a vibration damping element disposed between the mounting portion and the heat exchanger.

[0011] In one embodiment, the shock absorber is made of sponge.

[0012] In one embodiment, the indoor unit further includes fasteners, through which the first frame plate is connected to the heat exchanger.

[0013] In one embodiment, the indoor unit further includes a chassis, and at least one of the heat exchanger and the fan assembly is connected to the chassis.

[0014] In one embodiment, a reinforcing structure is provided on the side of the first frame plate opposite to the heat exchanger, the reinforcing structure connecting the first frame plate and the fan assembly; and / or, the fan assembly includes a duct shell, the first frame plate and the duct shell being integrally formed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] To improve the efficiency of air conditioner assembly, this technical solution proposes an indoor unit, including:

[0034] Fan assembly 100, having an air inlet side 110;

[0035] Heat exchanger 200 is located on one side of air inlet side 110 and connected to fan assembly 100. Heat exchanger 200 has a long side 230 facing air inlet side 110 and a short side 220 adjacent to the long side 230.

[0036] The first frame plate 310 is located on the air inlet side 110. The first frame plate 310 has a first positioning surface 3101 and a step 311 is formed on the first frame plate 310. The step 311 has a second positioning surface 3111. The first positioning surface 3101 abuts against the short side 220 and the second positioning surface 3111 abuts against the long side 230.

[0037] In the technical solution of this utility model, the air inlet side 110 of the fan assembly 100 is provided with a first frame plate 310. The first frame plate 310 has a first positioning surface 3101 on the side facing the heat exchanger 200. A step 311 is also provided on the side of the first frame plate 310 facing the heat exchanger 200. The step 311 has a second positioning surface 3111. When the heat exchanger 200 is assembled with the fan assembly 100, the long side 230 of the heat exchanger 200 facing the air inlet side 110 can be aligned with the second positioning surface 3111. The positioning surface 3111 abuts, and the short side 220 of the heat exchanger 200 adjacent to the long side 230 can abut with the first positioning surface 3101. In this way, both the first positioning surface 3101 and the second positioning surface 3111 limit the heat exchanger 200. This not only ensures the positional accuracy of the heat exchanger 200 after it is assembled with the fan assembly 100, but also allows the heat exchanger 200 to be easily positioned by the first frame plate 310 and the step 311 during assembly without repeated adjustments, thereby improving assembly efficiency.

[0038] like Figures 1 to 8 In one embodiment of this utility model, the indoor unit includes a fan assembly 100, which includes a duct shell for airflow and a fan disposed within the duct shell. The fan drives airflow in and out of the duct shell. Additionally, the fan assembly 100 has an air inlet side 110, which can be an air inlet on the duct shell, allowing airflow to enter and flow through the fan assembly 100. Furthermore, the indoor unit also includes a heat exchanger 200, which can be a condenser or an evaporator. The heat exchanger 200 is positioned opposite the air inlet side 110. External airflow can enter the heat exchanger 200 and exchange heat to form hot or cold airflow, which then enters the air inlet side 110 and is finally discharged into the environment from the fan assembly 100, thus achieving a heating or cooling process. To facilitate the assembly of the fan assembly 100 and the heat exchanger 200, a first frame plate 310 is provided on the air inlet side 110. A step 311 is formed on the first frame plate 310, and the step 311 abuts against the long side 230 of the heat exchanger 200. The heat exchanger 200 is initially designed to have two opposing short sides 220 (the two sides on which the side plate 210 is mounted) along its length, and a long side 230 directly opposite the air inlet side 110. The first frame plate 310 is located at one end of the air inlet side 110 along the length of the heat exchanger 200. Furthermore, a protrusion forming a step 311 is provided on the side of the first frame plate 310 facing the heat exchanger 200. Figure 4 The first frame plate 310 has a first positioning surface 3101 on the side facing the heat exchanger 200, and the step 311 has a second positioning surface 3111 on the side facing the heat exchanger 200. In this solution, the first positioning surface 3101 and the second positioning surface 3111 can be perpendicular to each other. When the heat exchanger 200 is assembled, the short side 220 of the heat exchanger 200 can abut against the first positioning surface 3101, and the long side 230 of the heat exchanger 200 can abut against the second positioning surface 3111, which restricts the heat exchanger 200 from continuing to move towards the air inlet side 110. After that, the heat exchanger 200 can be connected to the fan assembly 100 by means of screws or the like to complete the assembly. In the above solution, by setting the first frame plate 310 and the step 311 on the first frame plate 310, the heat exchanger 200 can be positioned in two directions: along the length of the heat exchanger 200 and along the direction close to the air inlet side 110. This facilitates the assembly of the heat exchanger 200 and also helps to improve assembly accuracy, assembly efficiency, and assembly quality. Furthermore, in another embodiment of this utility model, multiple first frame plates 310 can be provided, for example... Figure 3As shown, two first frame plates 310 can be provided, and each first frame plate 310 can be provided with a step 311. The two first frame plates 310 are spaced apart along the length direction of the heat exchanger 200 and clamp the short side 220 of the heat exchanger 200. The two first frame plates 310 are parallel to each other and form an installation space between them. During assembly, the heat exchanger 200 can be embedded into the installation space. At this time, the two first frame plates 310 respectively abut against the two short side 220 of the length direction of the heat exchanger 200. The two first frame plates 310 cooperate to clamp the heat exchanger 200, further ensuring the stability of the heat exchanger 200 after installation.

[0039] like Figures 6 to 8 In one embodiment of the present invention, a side plate 210 is provided on the short side 220 of the heat exchanger 200, and the indoor unit also includes a second frame plate 320. The second frame plate 320 is located at the bottom of the air inlet side 110, and a limiting groove 321 is provided on the second frame plate 320. The side plate 210 is inserted into the limiting groove 321. In this design, the side plate 210 is wider than the heat exchanger 200 itself in the width direction. The second frame plate 320 is located on the air inlet side 110 near the chassis 600. The second frame plate 320 has recesses at both ends near the two first frame plates 310 to form limiting grooves 321. When the heat exchanger 200 is assembled, the edge of the side plate 210 can be inserted into the limiting groove 321. In this design, the edge of the side plate 210 is bent into an L-shape, and the bending size is adapted to the groove width of the limiting groove 321. Thus, after the side plate 210 is embedded in the limiting groove 321, the limiting groove 321 can limit the side plate 210 and restrict the heat exchanger 200 from moving along the length direction of the heat exchanger 200. This can further improve the positioning effect of the heat exchanger 200 and make the heat exchanger 200 better assembled during assembly, which is also conducive to improving the assembly efficiency.

[0040] like Figure 2 and Figure 3 In one embodiment of this utility model, the indoor unit further includes a mounting part 120, which is disposed on the top of the fan assembly 100. The mounting part 120 is used to install the electrical control box and abuts against the top of the heat exchanger 200. The mounting part 120 can be integrally formed with the duct shell in the fan assembly 100. The mounting part 120 can be used to place the electrical control box, which facilitates the installation of the electrical control box and reduces the number of parts in the indoor unit. Furthermore, the mounting part 120 is disposed on the air inlet side 110, and during assembly, the mounting part 120 abuts against the top of the heat exchanger 200, thus improving the stability and reliability of the heat exchanger 200 after assembly with the fan assembly 100.

[0041] like Figure 2In one embodiment of this utility model, the indoor unit further includes a vibration damping component 400, which is disposed between the mounting portion 120 and the heat exchanger 200. The vibration damping component 400 can be made of elastic materials such as silicone. After assembly, the vibration damping component 400 is clamped between the heat exchanger 200 and the mounting portion 120 and is in a compressed state. Thus, when the heat exchanger 200 or the mounting portion 120 vibrates, the vibration damping component 400 can absorb the vibration, preventing abnormal noise generated by friction between the heat exchanger 200 and the fan assembly 100, thereby improving the operating quality of the indoor unit. In this solution, the vibration damping component 400 is made of sponge material, preferably solid PE material. This utilizes the porous nature of sponge to absorb noise and also allows airflow to leak from the gap between the heat exchanger 200 and the mounting portion 120, further improving the operating quality of the indoor unit.

[0042] like Figure 1 and Figure 2 In one embodiment of this utility model, the indoor unit further includes fasteners 500, and the first frame plate 310 is connected to the heat exchanger 200 via fasteners 500. In this solution, the fasteners 500 can be screws, and corresponding connection holes can be provided on the first frame plate 310 and the side plate 210 of the heat exchanger 200. The first frame plate 310 and the heat exchanger 200 are connected by the fasteners 500. Since the first frame plate 310 protrudes from the air inlet side 110, this ensures connection strength while facilitating the assembly of the fasteners 500. In addition, each first frame plate 310 can be connected to the heat exchanger 200 via multiple fasteners 500 to further improve the connection strength.

[0043] like Figure 1 and Figure 2 In one embodiment of this utility model, the indoor unit further includes a chassis 600, and at least one of the heat exchanger 200 and the fan assembly 100 is connected to the chassis 600. The chassis 600 forms part of the air conditioner casing and is located at the bottom of the indoor unit, supported on the ground. Both the heat exchanger 200 and the fan assembly 100 can be connected to the chassis 600, thus providing mutual support and ensuring the reliable connection of the various components of the indoor unit.

[0044] In addition, such as Figure 1 , Figure 3 , Figure 4 and Figure 8In one embodiment of this utility model, a reinforcing structure 700 is provided on the side of the first frame plate 310 facing away from the heat exchanger 200. The reinforcing structure 700 connects the first frame plate 310 and the fan assembly 100. The reinforcing structure 700 can be a reinforcing rib structure provided on the outside of the fan assembly 100. The reinforcing rib, the fan assembly 100, and the first frame plate 310 are integrated and can support each other, thereby improving the structural strength of the fan assembly 100 itself. In another embodiment of this utility model, the fan assembly 100 includes a duct shell. The first frame plate 310 and the duct shell are integrally formed, for example, by integral injection molding. This not only reduces the connecting structure but also improves the connection strength between the first frame plate 310 and the duct shell.

[0045] This utility model also proposes an air conditioner, including the above-mentioned indoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] In one embodiment, the air conditioner includes an indoor unit and an outdoor unit. The indoor unit is the same as in the previous embodiment. The indoor and outdoor units are connected by flexible refrigerant pipes pre-filled with refrigerant. Refrigerant can be pre-filled into the refrigerant circuit at the factory. During installation, only the indoor and outdoor units need to be fixed separately, without the need to assemble the refrigerant pipes or add refrigerant, thus reducing installation difficulty and enabling individual user installation. Furthermore, the flexible refrigerant pipes allow for some relative displacement between the indoor and outdoor units, ensuring the pipes' airtightness and preventing refrigerant leakage. In another embodiment, the compressor can be mounted on the indoor unit to reduce the weight of the outdoor unit, facilitating its installation. Additionally, the compressor on the indoor unit can be equipped with a noise reduction structure to reduce operating noise and improve user experience. In another embodiment, the indoor unit is provided with four casters at the bottom. The four casters are respectively located at the four corners of the bottom of the air conditioner chassis 600. The indoor unit is supported on the ground by the casters and can move on the ground. In this way, the indoor unit can be moved to any position in the room according to the usage needs, which improves the flexibility of the air conditioner.

[0047] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
