[0039] Air conditioners include split air conditioners and integrated air conditioners. Air conditioners are used for cooling or heating to change the temperature of the surrounding environment. Taking a split air conditioner as an example, a split air conditioner includes an indoor unit and an outdoor unit, and the indoor unit is connected to the outdoor unit through a refrigerant pipe.

[0040] Reference Figure 1 and Figure 2As shown, an air conditioner of an embodiment of the utility model includes an indoor unit 1000, and the indoor unit 1000 includes a chassis 100 and a heat exchanger 200. When the air conditioner is cooling, the heat exchanger 200 is an evaporator. The chassis 100 includes a bottom plate 101 and a side plate 102 connected to each other, and the bottom plate 101 and the side plate 102 are arranged at an angle. The chassis 100 is provided with an installation space 110, and the installation space 110 is a space defined between the bottom plate 101 and the side plate 102 of the chassis 100. A mounting seat 120 is provided in the installation space 110, and the mounting seat 120 can be a structure for installing a motor, or a structure for avoiding a refrigerant pipe. Taking a wall-mounted air conditioner as an example, the mounting seat 120 of the indoor unit 1000 is usually used to avoid a refrigerant pipe. Since the indoor unit 1000 is installed on a wall, in order to reduce the space occupied by the indoor unit 1000, one side of the indoor unit 1000 is required to fit the wall. The indoor unit 1000 needs to be connected to the outdoor unit through a refrigerant pipe, and one end of the refrigerant pipe is usually located on the side of the indoor unit 1000 that is in contact with the wall. Therefore, the mounting seat 120 needs to protrude toward the inner side of the installation space 110, and the mounting seat 120 is provided with an avoidance groove 121 for avoiding the refrigerant pipe, so that one side of the indoor unit 1000 can be in contact with the wall, and structures such as the refrigerant pipe and cables can extend from the inside of the indoor unit 1000 to the outside.

[0041] Reference Figure 1 As shown, the heat exchanger 200 is disposed in the installation space 110 and is fixedly connected to the chassis 100. The heat exchanger 200 includes a heat exchange body 210, a side plate 220 and a bend 230. Figure 1 In the left and right directions of the heat exchange body 210, the heat exchange body 210 and the mounting seat 120 are arranged at intervals. The side of the heat exchange body 210 facing the mounting seat 120 is connected with a side plate 220 and a bend 230. There are multiple bends 230, and the multiple bends 230 protrude from the side plate 220 and are connected to the corresponding heat exchange pipes in the heat exchange body 210. The bends 230 and the mounting seat 120 are arranged at intervals to facilitate the installation of the heat exchanger 200 and avoid deformation, bending, etc. of the bends 230 due to collision between the bends 230 and the mounting seat 120.

[0042] In order to make the structure of the indoor unit 1000 compact, the gap between the elbow 230 and the mounting seat 120 is usually not too large to ensure smooth assembly. During the transportation of the air conditioner, the air conditioner may fall due to improper packaging, bumps and other factors. The heat exchanger 200 has a large weight. Although it is fixedly connected to the chassis 100, the connection between the heat exchanger 200 and the chassis 100 is prone to deformation, causing relative displacement between the heat exchanger 200 and the chassis 100, resulting in the elbow 230 directly hitting the mounting seat 120. The elbow 230 is prone to deformation, bending or breaking, and the safety and reliability of the indoor unit 1000 are reduced.

[0043] In order to reduce the risk of the elbow 230 hitting the mounting seat 120, refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 7 As shown, in the embodiment of the utility model, the chassis 100 is provided with a first stopper 130, and the first stopper 130 is located in the installation space 110. The side plate 220 is provided with a second stopper 240, and the second stopper 240 and the first stopper 130 are used to limit the collision between the elbow 230 and the mounting seat 120. For example, when the indoor unit 1000 falls, the heat exchanger 200 and the chassis 100 produce relative displacement and move toward the mounting seat 120. At this time, the first stopper 130 and the second stopper 240 abut to limit the heat exchanger 200 from continuing to move toward the mounting seat 120, thereby effectively reducing the collision between the elbow 230 and the mounting seat 120, resulting in deformation, fracture, etc. of the elbow 230, and improving the safety and reliability of the air conditioner.

[0044] Reference Figure 7 As shown, in an embodiment of the utility model, the first stopper 130 and the chassis 100 are integrally formed, and the second stopper 240 and the side plate 220 are integrally formed. For example, the chassis 100 is made of plastic, so the first stopper 130 and the chassis 100 can be integrally injection molded. The side plate 220 is made of sheet metal material, and the side plate 220 and the second stopper 240 can be integrally formed by stamping, cutting, etc. The integral molding method can simplify the structure of the first stopper 130 and the second stopper 240, improve the stability and reliability of the connection, and reduce the risk of loosening and falling off. When the indoor unit 1000 falls, it is effectively ensured that the first stopper 130 and the second stopper 240 abut to limit the relative position of the heat exchanger 200 and the chassis 100, and avoid collision between the elbow 230 and the mounting seat 120.

[0045] In other embodiments, the first stopper 130 and the chassis 100 may be connected by fasteners, clamping, etc., and the second stopper 240 and the side plate 220 may be integrally formed. Alternatively, the first stopper 130 and the chassis 100 may be integrally formed, and the second stopper 240 may be fixedly connected to the side plate 220 by fasteners, clamping, welding, etc. Alternatively, the first stopper 130 and the chassis 100 may be connected by fasteners, clamping, etc., and the second stopper 240 may be fixedly connected to the side plate 220 by fasteners, clamping, welding, etc. The appropriate connection method may be selected according to the actual situation.

[0046] Reference Figure 7As shown, in the embodiment of the utility model, the first limiter 130 is one of the buckle 241 or the slot 131, and the second limiter 240 is the other of the buckle 241 or the slot 131, and the buckle 241 is inserted into the slot 131. For example, the first limiter 130 can be the buckle 241, and the second limiter 240 is the slot 131; or the first limiter 130 is the slot 131, and the second limiter 240 is the buckle 241. With the scheme of the buckle 241 and the slot 131, the heat exchanger 200 is simple and convenient to install on the chassis 100, and the assembly efficiency is high. When the indoor unit 1000 falls, the buckle 241 and the inner wall of the slot 131 abut and cooperate, which can further limit the heat exchanger 200 from moving in the direction close to the mounting seat 120.

[0047] Continue to refer to Figure 7 As shown, in the embodiment of the present invention, the first stopper 130 is a slot 131, and the second stopper 240 is a buckle 241. The slot 131 is formed in the installation space 110, and the buckle 241 is extended along a direction perpendicular to the thickness of the side plate 220. For example, the thickness direction of the side plate 220 is Figure 7 The left-right direction in the figure, and the direction perpendicular to the left-right direction can be the up-down direction, so the buckle 241 is extended from top to bottom, and the opening of the card slot 131 is set upward, which is conducive to the insertion of the buckle 241 into the card slot 131. During installation, the heat exchanger 200 is positioned on the chassis 100 from top to bottom, so that the buckle 241 is inserted into the card slot 131, and then the heat exchanger 200 is fixed to the chassis 100 by fasteners such as screws, and the process of installing the heat exchanger 200 is simple and convenient. Among them, when the buckle 241 is inserted into the card slot 131, it can limit the movement of the heat exchanger 200 in the left-right direction to a certain extent, thereby playing a certain positioning role, which is convenient for subsequent screw fixing.

[0048] Reference Figure 5 and Figure 7 As shown, in the embodiment of the present invention, along the length direction of the heat exchanger 200, for example Figure 5 and Figure 7In the left and right directions, the minimum gap between the inner wall of the slot 131 close to the mounting seat 120 and the buckle 241 is L1, and the minimum gap between the elbow 230 and the mounting seat 120 is L2, satisfying: L1<L2. It should be noted that when there are multiple elbows 230, the minimum gap between the elbow 230 and the mounting seat 120 refers to: the elbow 230 closest to the mounting seat 120. It can be understood that, assuming that L2 is less than or equal to L1, when the indoor unit 1000 falls, it is easy to cause the elbow 230 to collide with the mounting seat 120 before the buckle 241, resulting in deformation and fracture of the elbow 230. Therefore, by setting L1 to be less than L2, so that the buckle 241 first contacts the inner wall of the slot 131, thereby reducing or avoiding the situation where the elbow 230 hits the mounting seat 120, and improving the reliability of the indoor unit 1000.

[0049] It is understandable that after the indoor unit 1000 is assembled, the buckle 241 and the inner wall of the slot 131 are spaced apart, so there is a gap between the two. Since there are deviations in the structures such as the chassis 100 and the side plate 220 during manufacturing, there are also deviations during installation; if the buckle 241 is designed to contact the inner wall of the slot 131, it is easy to fail to install due to errors, or cause the buckle 241 and the slot 131 to always have a pre-tightening force, shortening the service life of the buckle 241. Therefore, the buckle 241 is designed to be spaced apart from the inner wall of the slot 131, so that even if there are size errors and installation errors, it can be installed smoothly, the structural design is reasonable, and the assembly efficiency of the indoor unit 1000 is improved.

[0050] Reference Figure 5 and Figure 7As shown, in the embodiment of the utility model, the minimum gap L1 between the buckle 241 and the inner wall of the slot 131 close to the mounting seat 120 satisfies: 0.5mm≤L1≤3mm, and the minimum gap L2 between the elbow 230 and the mounting seat 120 satisfies: 6mm≤L2≤10mm. When L1 is less than 0.5mm, the gap between the buckle 241 and the slot 131 is too small, and the buckle 241 may not be inserted into the slot 131 due to the error problem, which affects the installation of the heat exchanger 200. When L1 is greater than 3mm, the gap between the buckle 241 and the slot 131 is too large, and it is difficult to limit the movement of the heat exchanger 200 toward the mounting seat 120 when the indoor unit 1000 falls. Therefore, a reasonable design of the size of L1 can ensure that the buckle 241 can be smoothly installed in the slot 131, and can also reduce or avoid the risk of collision between the elbow 230 and the mounting seat 120 when the indoor unit 1000 accidentally falls. When L2 is less than 6 mm, the distance between the elbow 230 and the mounting seat 120 is too close, and when the indoor unit 1000 falls, relative displacement between the heat exchanger 200 and the chassis 100 may occur, causing the elbow 230 and the mounting seat 120 to collide. When L2 is greater than 10 mm, the size of the indoor unit 1000 in its length direction may increase, which is not conducive to the miniaturization of the indoor unit 1000, increases the packaging volume, and increases the transportation cost. Therefore, the size of L2 is reasonably designed, and when the indoor unit 1000 falls, the probability of the elbow 230 and the mounting seat 120 colliding can be reduced, thereby improving the safety and reliability of the indoor unit 1000.

[0051] Reference Figure 8 and Fig. 9 As shown, in another embodiment of the utility model, the first limiter 130 is one of the stopper 132 or the protrusion 242, and the second limiter 240 is the other of the stopper 132 or the protrusion 242. For example, the first limiter 130 is the stopper 132, and is fixedly connected to the inner wall of the installation space 110, and is located between the side plate 220 and the mounting seat 120. Or the stopper 132 is directly fixedly connected to the mounting seat 120 on the side facing the side plate 220, and the fixed connection method can be one-piece molding, clamping or fastener connection. The second limiter 240 is the protrusion 242, and the protrusion 242 is a structure formed by a part of the structure of the side plate 220 protruding toward the direction of the stopper 132. The protrusion 242 and the stopper 132 are used to limit the collision between the elbow 230 and the mounting seat 120. When the indoor unit 1000 falls, the protrusion 242 moves toward the stopper 132 and abuts against the stopper 132 , thereby limiting the heat exchanger 200 from continuing to move toward the mounting seat 120 , reducing or avoiding the collision between the elbow 230 and the mounting seat 120 .

[0052] Reference Fig. 9As shown, in the embodiment of the utility model, taking the first limiting member 130 as the stopper 132 and the second limiting member 240 as the protrusion 242 as an example, the chassis 100 includes a fixing seat 111 disposed in the installation space 110, and the side plate 220 includes a connecting portion 221, and the connecting portion 221 is fixedly connected to the fixing seat 111, and the fixed connection method can be a snap connection, a fastener screw connection, etc., for example, the connecting portion 221 is fixed to the fixing seat 111 by a screw 222, so as to limit the position of the heat exchanger 200. The connecting portion 221 has a connecting surface 223 on one side facing the mounting seat 120, and the protrusion 242 is disposed on the connecting surface 223. It can be understood that by setting the protrusion 242 on the connecting surface 223 of the connecting part 221, when the indoor unit 1000 falls, the abutment between the protrusion 242 and the block 132 can prevent the connecting part 221 and the fixing seat 111 from further deformation, thereby improving the stability of the connection between the connecting part 221 and the fixing seat 111, effectively reducing or avoiding the deformation of the connecting part 221, thereby limiting the collision between the bent pipe 230 and the mounting seat 120, and improving the safety and reliability of the indoor unit 1000 when it falls.

[0053] Reference Fig.10 and Fig.11 As shown, in the embodiment of the present invention, along the length direction of the heat exchanger 200, for example Fig.10 In the left and right directions, the minimum gap between the stopper 132 and the protrusion 242 is L3, and the minimum gap between the elbow 230 and the mounting seat 120 is L2, which satisfies: L3<L2. It should be noted that when there are multiple elbows 230, the minimum gap between the elbow 230 and the mounting seat 120 refers to: the elbow 230 that is closest to the mounting seat 120. It can be understood that, assuming that L2 is less than or equal to L3, when the indoor unit 1000 falls, it is easy to cause the elbow 230 to abut against the mounting seat 120 before the protrusion 242, resulting in deformation and fracture of the elbow 230. Therefore, by setting L3 to be less than L2, so that the protrusion 242 abuts against the stopper 132 first, the situation of the elbow 230 hitting the mounting seat 120 is reduced or avoided, thereby improving the reliability of the indoor unit 1000.

[0054] Among them, after the indoor unit 1000 is assembled, the protrusion 242 and the stopper 132 are spaced apart, so there is a gap between them. Since there are deviations in the structures such as the chassis 100 and the side plate 220 during manufacturing, there are also deviations during installation; if the protrusion 242 and the stopper 132 are designed to abut against each other, it is easy to fail to install due to errors, or there will always be a pre-tightening force between the protrusion 242 and the stopper 132, shortening the service life of the protrusion 242. Therefore, the protrusion 242 is designed to be spaced apart from the stopper 132, so that even if there are size errors and installation errors, it can be installed smoothly, the structural design is reasonable, and the assembly efficiency of the indoor unit 1000 is improved.

[0055] Reference Fig.11 As shown, in the embodiment of the utility model, the minimum gap L3 between the protrusion 242 and the stopper 132 satisfies: 0.5mm≤L3≤3mm, and the minimum gap L2 between the elbow 230 and the mounting seat 120 satisfies: 6mm≤L2≤10mm. When L3 is less than 0.5mm, the gap between the protrusion 242 and the stopper 132 is too small, and it is easy to cause the protrusion 242 to directly abut against the stopper 132 due to the error problem, affecting the installation of the heat exchanger 200. When L3 is greater than 3mm, the gap between the protrusion 242 and the stopper 132 is too large, and it is difficult to limit the movement of the heat exchanger 200 toward the mounting seat 120 when the indoor unit 1000 falls. Therefore, a reasonable design of the size of L3 can ensure the smooth installation of the heat exchanger 200, and can also reduce or avoid the risk of collision between the elbow 230 and the mounting seat 120 when the indoor unit 1000 accidentally falls. When L2 is less than 6 mm, the distance between the elbow 230 and the mounting seat 120 is too close, and when the indoor unit 1000 falls, the relative displacement between the heat exchanger 200 and the chassis 100 may cause the elbow 230 and the mounting seat 120 to collide. When L2 is greater than 10 mm, the size of the indoor unit 1000 in its length direction may increase, which is not conducive to the miniaturization of the indoor unit 1000, and the packaging volume may increase, which may increase the transportation cost. Therefore, the size of L2 is reasonably designed, and when the indoor unit 1000 falls, the probability of the elbow 230 and the mounting seat 120 colliding can be reduced, thereby improving the safety and reliability of the indoor unit 1000.
