[0041] The embodiments of the present application will be described in detail below with reference to the drawings, wherein the same or similar components are denoted by the same reference numerals throughout the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

For the purpose of simplification, the components and arrangements of the specific examples are described in the following. Of course, they are only examples and are not intended to limit the present application. In addition, the present application can repeatedly refer to the numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the applicability of other processes and / or the use of other materials.

[0043] The air conditioner 100 according to the embodiments of the present application will be described below with reference to the drawings.

[0044] As shown in Figure 1 and Figure 2 The air conditioner 100 according to the embodiments of the present application includes a shell assembly 1 and a heat exchanger 2, the heat exchanger 2 is arranged in the shell assembly 1 and includes a heat exchanger body 21 and a connecting pipe 22 arranged on the heat exchanger body 21, the connecting pipe 22 and the heat exchanger body 21 are arranged along a first direction, a plurality of refrigerant passages are formed in the heat exchanger body 21, two adjacent refrigerant passages are communicated by the connecting pipe 22, the shell assembly 1 includes a first side wall 11, the first side wall 11 is arranged opposite to and spaced apart from part of the connecting pipe 22 along the first direction, an avoiding groove 111 is formed on the side of the first side wall 11 facing the connecting pipe 22, and the connecting pipe 22 is arranged spaced apart from the inner wall surface of the avoiding groove 111.

[0045] That is, the connecting pipe 22 is connected to the end of the heat exchanger body 21 in the first direction, and the avoiding groove 111 is formed on the part of the first side wall 11 opposite to the connecting pipe 22 in the first direction. Since the avoiding groove 111 is recessed on the side of the first side wall 11 opposite to the connecting pipe 22, that is, the avoiding groove 111 is recessed in the first direction towards the direction away from the connecting pipe 22, the distance between the inner bottom wall of the first side wall 11 and the connecting pipe 22 in the first direction can be increased, so that sufficient movement avoiding space for the connecting pipe 22 in the first direction can be provided. Therefore, when the air conditioner 100 falls during transportation, the connecting pipe 22 can be prevented from being damaged by colliding with the first side wall 11 due to movement of the heat exchanger 2 by the avoiding groove 111, so that the risk of leakage due to collision and deformation of the connecting pipe 22 can be avoided, thereby improving the safety of transportation of the air conditioner 100.

[0046] According to the air conditioner 100 of the embodiment of the present application, when the air conditioner 100 falls during transportation, the connecting pipe 22 can be prevented from being damaged by colliding with the first side wall 11 due to movement of the heat exchanger 2 by the avoiding groove 111, so that the risk of leakage due to collision and deformation of the connecting pipe 22 can be avoided, thereby improving the safety of transportation of the air conditioner 100.

[0047] According to some embodiments of the present application, in the first direction, the inner wall surface of the avoiding groove 111 opposite to the connecting pipe 22 is a first avoiding surface, and the distance between the connecting pipe 22 and the first avoiding surface is not less than 10mm. It can be understood that the farther the distance between the first avoiding surface and the connecting pipe 22 in the first direction, the greater the space reserved for the movement of the connecting pipe 22 in the first direction, in other words, the lower the possibility of the connecting pipe 22 contacting the first avoiding surface. Therefore, by controlling the distance between the connecting pipe 22 and the first avoiding surface in the first direction to be not less than 10mm, sufficient avoiding space between the connecting pipe 22 and the first avoiding surface is ensured to prevent the risk of leakage due to collision and deformation of the connecting pipe 22, thereby improving the safety of transportation of the air conditioner 100. For example, the distance between the connecting pipe 22 and the first avoiding surface in the first direction can be 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, etc.

[0048] According to some embodiments of the present application, the connecting pipe 22 is an arc-shaped pipe, and the inner wall surface of the avoiding groove 111 is in the shape of a circular arc. In this way, the inner wall surface of the avoiding groove 111 can better match the shape of the connecting pipe 22, so that the distance between the connecting pipe 22 and the inner wall surface of the avoiding groove 111 can be more accurately controlled, to ensure that the distance between the side of the connecting pipe 22 in the first direction towards the first side wall 11 and the inner wall surface of the avoiding groove 111 is controlled to be above a safe distance (such as 10mm), to ensure the avoiding effect of the avoiding groove 111.

[0049] According to some embodiments of the present application, as shown in Figure 3 and Figure 4 The first side wall 11 is convex to form a convexity 112 in the first direction away from the heat exchanger 2, and the avoidance groove 111 is formed in the convexity 112. That is, the part of the first side wall 11 opposite to the connecting pipe 22 in the first direction is convex to form a convexity 112 in the direction away from the heat exchanger 2, and with the formation of the convexity 112, the first side wall 11 forms an avoidance groove 111 on the side facing the connecting pipe 22. Therefore, in the production and design process of the cabinet assembly 1, only the structure corresponding to the convexity 112 needs to be added to the mold of the part of the first side wall 11, that is, the avoidance groove 111 is formed on the side of the first side wall 11 facing the connecting pipe 22 while ensuring that the wall thickness of the first side wall 11 remains unchanged, which can reduce the material cost required to form the avoidance groove 111.

[0050] According to some embodiments of the present application, as shown in Figures 3 to 6 The air conditioner 100 further comprises a refrigerant inlet and outlet pipe 3, and the cabinet assembly 1 further comprises a second side wall 12 opposite to and spaced apart from the first side wall 11. In the first direction, the second side wall 12 is located on the side of the first side wall 11 away from the heat exchanger 2 and cooperates with the first side wall 11 to define a pipe running space 13, the refrigerant inlet and outlet pipe 3 is connected with the heat exchanger 2 and runs along the pipe running space 13, the side of the second side wall 12 facing the first side wall 11 is a first side surface 121, and the first side surface 121 is formed with an avoidance structure opposite to the convexity 112, the side of the avoidance structure facing the first side wall 11 is a second avoidance surface 122, and the distance between the second avoidance surface 122 and the convexity 112 is greater than the distance between the first side surface 121 and the convexity 112.

[0051] The one end of the refrigerant inlet and outlet pipe 3 is located in the cabinet assembly 1 and connected with the heat exchanger 2, and the other end of the refrigerant inlet and outlet pipe 3 extends to the outside of the cabinet assembly 1 through the pipe running space 13 to be connected with other components such as a compressor, the refrigerant inlet and outlet pipe 3 is connected with the heat exchanger 2 to transport refrigerant into the heat exchanger 2 and output refrigerant from the heat exchanger 2, thereby realizing continuous circulation of refrigerant in the heat exchanger 2. That is, the part of the first side wall 11 opposite to the connecting pipe 22 in the first direction extends to form a convexity 112 in the direction close to the second side wall 12, and the convexity 112 occupies part of the space in the pipe running space 13. Therefore, by providing the avoidance structure on the first side surface 121, an avoidance space can be provided for the part of the refrigerant inlet and outlet pipe 3 running along the pipe running space 13, thereby avoiding the convexity 112 lifting the refrigerant inlet and outlet pipe 3 to affect the pipe running arrangement of the refrigerant inlet and outlet pipe 3.

[0052] In one specific example, the first direction is the left-right direction, and the cabinet assembly 1 further has a connecting side wall formed thereon, the connecting side wall extending along the left-right direction and located between the first side wall 11 and the second side wall 12, the connecting side wall being located at the bottom of the pipe passing space 13, and the left and right ends of the connecting side wall being connected with the first side wall 11 and the second side wall 12 respectively, the first side wall 11, the second side wall 12 and the connecting side wall together defining the pipe passing space 13, and the structure strength at the position of the pipe passing space 13 can be better enhanced through the first side wall 11, the second side wall 12 and the connecting side wall to prevent the structure around the pipe passing space 13 from being deformed.

[0053] According to some embodiments of the present application, in the first direction, the distance between the second avoiding surface 122 and the first side surface 121 is greater than the height of the convexity 112. That is, in the first direction, the size of the avoiding space provided by the avoiding structure for the refrigerant inlet and outlet pipe 3 is greater than the size of the space occupied by the convexity 112 in the pipe passing space 13. Thus, the effect of the avoiding structure avoiding the refrigerant inlet and outlet pipe 3 can be better ensured to prevent the refrigerant inlet and outlet pipe 3 from being pressed by contacting the second side wall 12.

[0054] According to some embodiments of the present application, in the first direction, the distance between the second avoiding surface 122 and the first side surface 121 ranges from 4mm to 8mm. That is, the size of the avoiding space provided by the avoiding structure for the refrigerant inlet and outlet pipe 3 in the first direction is controlled in the range of 4mm to 8mm. It can be understood that the farther the distance between the second avoiding surface 122 and the first side surface 121 in the first direction, the greater the avoiding space provided by the avoiding structure for the refrigerant inlet and outlet pipe 3 in the first direction, but the avoiding structure occupies more space in the first direction, which is not conducive to the overall structure strength of the cabinet assembly 1; on the contrary, the closer the distance between the second avoiding surface 122 and the first side surface 121 in the first direction, the less space the avoiding structure occupies in the first direction, and the less the avoiding structure affects the overall structure strength of the cabinet assembly 1, but the avoiding space provided by the avoiding structure for the refrigerant inlet and outlet pipe 3 in the first direction is smaller. Therefore, by controlling the distance between the second avoiding surface 122 and the first side surface 121 in the first direction to be 4mm to 8mm, the avoiding structure can provide sufficient avoiding space for the refrigerant inlet and outlet pipe 3 while reducing the impact on the overall structure strength of the cabinet assembly 1. For example, the distance between the second avoiding surface 122 and the first side surface 121 in the first direction can be 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc.

[0055] According to some embodiments of the present application, the size of the second avoiding surface 122 in the second direction is 20mm-30mm, and the second direction is perpendicular to the first direction. It can be understood that the larger the size of the second avoiding surface 122 in the second direction, the larger the avoiding space provided for the refrigerant inlet and outlet pipe 3 in the second direction, but the larger the space occupied by the avoiding structure in the second direction, the more the avoiding space, which is not conducive to the overall structural strength of the shell assembly 1; on the contrary, the smaller the size of the second avoiding surface 122 in the second direction, the smaller the space occupied by the avoiding structure in the second direction, and the smaller the avoiding space provided for the refrigerant inlet and outlet pipe 3 in the first direction. Therefore, by controlling the size of the second avoiding surface 122 in the second direction to be 20mm-30mm, the influence on the overall structural strength of the shell assembly 1 can be reduced while ensuring that the avoiding structure provides sufficient avoiding space for the refrigerant inlet and outlet pipe 3. For example, the size of the second avoiding surface 122 in the second direction can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, etc.

[0056] According to some embodiments of the present application, the pipe running space 13 extends to the back of the shell assembly 1, and the second avoiding surface 122 extends to the back of the shell assembly 1. That is, the refrigerant inlet and outlet pipe 3 can run to the back of the shell assembly 1 through the pipe running space 13 to run along the back of the shell assembly 1, and the second avoiding surface 122 extends to the back of the shell assembly 1 together with the pipe running space 13, thereby ensuring that the avoiding structure can provide an avoiding effect for the refrigerant inlet and outlet pipe 3 during the process of leading the refrigerant inlet and outlet pipe 3 out of the shell assembly 1 along the pipe running space 13, to prevent the refrigerant inlet and outlet pipe 3 from contacting the second side wall 12.

[0057] In one specific example, the air conditioner 100 is a wall-mounted air conditioner, the shell assembly 1 comprises a bottom plate, the heat exchanger 2 is arranged on the bottom plate, the first direction is the left-right direction, the second direction is the front-back direction, the third direction is the front-back direction, the pipe running space 13 extends along the up-down direction and extends to the back of the bottom plate, so that the refrigerant inlet and outlet pipe 3 can extend to the back of the bottom plate through the pipe running space 13 and run along the back of the bottom plate, the first side face 121 is located in front of the second avoiding face 122, the step face 123 is formed between the first side face 121 and the second avoiding face 122, the width size of the step face 123 in the left-right direction is 6mm, the rear end of the second avoiding face 122 extends to the back of the bottom plate, and the width size of the second avoiding face 122 in the front-back direction is 25mm. Therefore, the forming difficulty of the avoiding structure can be reduced, that is, the avoiding structure can be formed by setting a step structure on the mold, and at the same time, it can be ensured that the avoiding structure can provide sufficient pipe running space 13 for the refrigerant inlet and outlet pipe 3. In addition, the second avoiding face 122 can be provided with a reinforcing rib extending along the front-back direction and connected with the step face 123, so that the influence of the avoiding structure on the structural strength of the second side wall 12 can be better compensated by the reinforcing rib.

[0058] According to some embodiments of the present application, Figure 7 and Figure 8 The heat exchanger 2 is provided with a limiting cooperation part 23, and the inner wall surface of the shell assembly 1 is provided with a limiting baffle 14, at least part of the limiting baffle 14 is located in the first direction and is arranged opposite to the limiting cooperation part 23. Therefore, through the part of the limiting baffle 14 and the limiting cooperation part 23 opposite in the first direction, the movement of the limiting cooperation part 23 in the first direction can be better blocked, so that the limiting cooperation part 23 can be limited, and the movement amplitude of the heat exchanger 2 in the first direction can be limited. Therefore, when the air conditioner 100 falls during transportation, through the cooperation of the limiting baffle 14 and the limiting cooperation part 23, the movement amplitude of the heat exchanger 2 in the first direction can be reduced, so that the displacement distance of the connecting pipe 22 towards the first side wall 11 can be reduced by controlling the movement distance of the heat exchanger 2, to avoid the connecting pipe 22 and the first side wall 11 from colliding and deforming to leak, which is beneficial to improve the transportation safety of the air conditioner 100.

[0059] According to some embodiments of the present application, the limiting baffle 14 is located on one side of the limiting fitting part 23 in the first direction towards the first side wall 11. That is, in the first direction, the limiting baffle 14 is located between the limiting fitting part 23 and the first side wall 11. Therefore, by the limiting baffle 14, the movement of the limiting fitting part 23 towards the first side wall 11 can be better blocked, so as to reduce the displacement amplitude of the heat exchanger 2 towards the first side wall 11, thereby reducing the displacement of the connecting pipe 22 towards the first side wall 11 when the air conditioner 100 falls, to avoid the connecting pipe 22 from colliding with the first side wall 11 and deforming to leak, and to improve the transportation safety of the air conditioner 100.

[0060] According to some embodiments of the present application, the side surface of the limiting baffle 14 opposite to the limiting fitting part 23 in the first direction is a limiting surface, and the limiting surface is arranged in a spaced manner with the limiting fitting part 23. That is, the limiting surface does not contact the limiting baffle 14. In this way, while ensuring the limiting effect of the limiting surface on the limiting fitting part 23, the contact and friction between the limiting baffle 14 and the limiting fitting part 23 can be avoided to increase the installation difficulty, so as to improve the installation efficiency of the heat exchanger 2.

[0061] According to some embodiments of the present application, the distance between the limiting fitting part 23 and the limiting surface in the first direction is 2mm-8mm. Wherein, the farther the distance between the limiting fitting part 23 and the limiting surface in the first direction, the lower the possibility of the limiting fitting part 23 contacting the limiting surface during the installation of the heat exchanger 2, but the limiting effect of the limiting surface on the limiting fitting part 23 in the first direction is worse; on the contrary, the farther the distance between the limiting fitting part 23 and the limiting surface in the first direction, the better the limiting effect of the limiting surface on the limiting fitting part 23 in the first direction, but the possibility of the limiting fitting part 23 contacting the limiting surface during the installation of the heat exchanger 2 is higher. Therefore, by controlling the distance between the limiting fitting part 23 and the limiting surface in the first direction within the range of 2mm-8mm, the limiting effect of the limiting baffle 14 on the limiting fitting part 23 can be ensured, and the contact between the limiting fitting part 23 and the limiting baffle 14 affecting the installation efficiency can be avoided. For example, the distance between the limiting fitting part 23 and the limiting surface in the first direction can be 2mm, 2.5mm, 3mm, 3.5m, 4mm, 5mm, 6mm, 7mm, 8mm, etc.

[0062] According to some embodiments of the present application, the heat exchanger 2 further comprises a side plate 24 arranged at the end of the heat exchanger body 21 in the first direction, and the side plate 24 is provided with a connecting lug 25 at one end in the second direction, the connecting lug 25 is connected to the inner wall surface of the shell assembly 1 along the third direction, and the limiting fitting part 23 is arranged on the connecting lug 25. That is, the limiting stop plate 14 can better limit the activity freedom of the connecting lug 25 in the first direction, so as to reduce the deformation amplitude of the side plate 24 when the air conditioner 100 falls. In addition, by arranging the limiting fitting part 23 on the connecting lug 25, the connecting lug 25 can be used as a limiting fitting structure cooperating with the limiting stop plate 14, and the limiting fitting structure cooperating with the limiting stop plate 14 is omitted, so that the structure of the heat exchanger 2 can be simplified.

[0063] According to some embodiments of the present application, the limiting fitting part 23 and the limiting stop plate 14 are located on the outer circumferential side of the heat exchanger body 21. That is, the cooperation position of the limiting fitting part 23 and the limiting stop plate 14 is located on the outer circumferential side of the heat exchanger body 21, wherein the outer circumferential side of the heat exchanger body 21 here refers to the outer circumferential area of the heat exchanger body 21 in the direction perpendicular to the first direction. Therefore, the heat exchanger body 21 can avoid shielding the limiting fitting part 23 and the limiting stop plate 14, so as to more intuitively and clearly observe the limiting fitting part 23 and the limiting stop plate 14, thereby reducing the cooperation difficulty of the limiting fitting part 23 and the limiting stop plate 14, and improving the installation efficiency of the heat exchanger 2.
