[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0044] Combination Figure 1-9 As shown, this embodiment of the present disclosure provides an indoor unit, including a housing 20 and a mounting bracket 10.

[0045] The outer casing 20 is provided with a connecting structure and a positioning part 204; the hanging foot 10 is provided with a connecting and mating structure and a positioning and mating part 108.

[0046] The positioning part 204 and the positioning mating part 108 are arranged in the vertical direction. When the lifting foot 10 is assembled into the outer casing 20, the connecting structure and the connecting mating structure are engaged, and as shown... Figure 6 As shown, the positioning part 204 and the positioning mating part 108 abut against each other in the vertical direction.

[0047] The outer casing 20 is provided with a connecting structure, and the hanging foot 10 is provided with a connecting and mating structure. When it is necessary to assemble the hanging foot 10 onto the outer casing 20, the connecting structure and the connecting and mating structure are mated to realize the assembly of the hanging foot 10 onto the outer casing 20 and realize the connection between the hanging foot 10 and the outer casing 20, so that the outer casing 20 can be assembled onto the wall through the hanging foot 10.

[0048] The outer casing 20 is provided with a positioning part 204, and the hanging feet 10 are provided with a matching positioning mating part 108. When the hanging feet 10 are assembled on the outer casing 20, the positioning part 204 and the positioning mating part 108 abut against each other in the vertical direction. In this way, the positioning part 204 can limit the position of the positioning mating part 108 in the height direction (i.e., the vertical direction), so that the positioning part 204 is fixed in the vertical direction, thereby making the height of the multiple hanging feet 10 consistent, that is, the multiple hanging feet 10 can be located in the same horizontal plane, so that the indoor unit can be placed horizontally.

[0049] The connection between the lifting leg 10 and the enclosure is more stable through the cooperation of the connecting structure and the connecting mating structure, and the cooperation between the positioning part 204 and the positioning mating part 108. This improves the installation reliability of the lifting leg 10 on the enclosure and also enhances the safety of the entire machine.

[0050] Optionally, such as Figures 1 to 4 , Figure 6 As shown, the connection structure includes a first connection part 201, and the connection mating structure includes a first connection mating part 1011. When the hanging foot 10 is assembled on the outer shell 20, the first connection part 201 and the first connection mating part 1011 are mated together.

[0051] The outer casing 20 is provided with a first bayonet 206, and a first connecting and mating part 1011 is inserted into the first bayonet 206. The positioning part 204 includes the connection between the first connecting part 201 and the outer casing 20, and the positioning and mating part 108 includes the connection between the first connecting and mating part 1011 and the lifting lug.

[0052] The connection structure includes a first connection part 201, and the connection mating structure includes a first connection mating part 1011. When the hanger 10 is assembled on the outer shell 20, the first connection part 201 and the first connection mating part 1011 cooperate to fix the hanger 10 and the outer shell 20, thereby realizing the assembly of the hanger 10 on the outer shell 20.

[0053] The outer casing 20 is provided with a first slot 206 extending through the thickness direction of the outer casing 20. The first connecting mating part 1011 is inserted into the inner side of the outer casing 20 through the first slot 206, so that the first connecting mating part 1011 and the first connecting part 201 cooperate. The positioning part 204 includes the connection between the first connecting part 201 and the outer casing 20, and the positioning mating part 108 includes the connection between the first connecting mating part 1011 and the lifting lug. In this way, when the lifting leg 10 is assembled with the outer casing 20, the first connecting part 201 and the first connecting mating part 1011 are engaged, and the positioning part 204 and the positioning mating part 108 abut against each other, simplifying the assembly steps of the lifting leg 10 and the outer casing 20 and improving assembly efficiency.

[0054] Optionally, the connection between the first connecting part 201 and the outer shell 20 is provided with a first notch 205 with an opening facing the positioning mating part 108, and the connection between the first connecting mating part 1011 and the lifting lug is provided with a second notch 106 with an opening facing the first notch 205, and the first notch 205 is inserted into the second notch 106.

[0055] The positioning part 204 includes the bottom wall of the groove with the first notch 205, and the positioning mating part 108 includes the bottom wall of the groove with the second notch 106.

[0056] like Figure 4 As shown, the outer edge of the first connecting portion 201 includes a first connecting edge 2014, a first free edge 2015, a first side edge 2016, and a second side edge 2017. The first connecting edge 2014 is connected to the outer shell 20. A first latch 206 is formed between the first free edge 2015 and the outer shell 20. The first free edge 2015 and the first connecting edge 2014 are disposed opposite to each other. The first side edge 2016 is connected between one end of the first connecting edge 2014 and one end of the first free edge 2015. The second side edge 2017 is connected between the other end of the first connecting edge 2014 and the other end of the first free edge 2015. The first side edge 2016 and the second side edge 2017 are disposed opposite to each other. A first notch 205 is provided between the connection point of the first side edge 2016 and the outer shell 20 and / or between the connection point of the second side edge 2017 and the outer shell 20.

[0057] like Figure 1 As shown, the outer edge of the first connecting and mating part 1011 includes a second connecting edge 1012, a second free edge 1013, a third side edge 1014, and a fourth side edge 1015. The second connecting edge 1012 is connected to the lifting leg 10, and the second free edge 1013 forms a second latch 1016 with the lifting leg 10, so that the first connecting and mating part 1011 can be inserted into the first latch 206 through the second free edge 1013 to realize the mating between the first connecting part 201 and the first connecting and mating part 1011. The second free edge 1013 is disposed opposite to the second connecting edge 1012, the third side edge 1014 is connected between one end of the second connecting edge 1012 and one end of the second free edge 1013, and the fourth side edge 1015 is connected between the other end of the second connecting edge 1012 and the other end of the second free edge 1013. The third side edge 1014 and the fourth side edge 1015 are disposed opposite to each other. The second notch 106 is located between the third side 1014 and the foot 10 and / or between the fourth side 1015 and the foot 10.

[0058] like Figures 1 to 4As shown, there are two first notches 205, located at the connection between the first side 2016 and the outer shell 20, and at the connection between the second side 2017 and the outer shell 20, respectively. There are also two second notches 106, which correspond one-to-one with the first notches 205. The two second notches 106 are located at the connection between the third side 1014 and the hanging foot 10, and at the connection between the fourth side 1015 and the hanging foot 10, respectively.

[0059] like Figure 6 and Figure 8 As shown, when the lifting leg 10 is assembled into the outer casing 20, the first connecting part 201 engages with the first connecting mating part 1011, and the first notch 205 is inserted into the second notch 106, so that the first notch 205 and the second notch 106 abut against each other, that is, the bottom wall of the groove of the first notch 205 abuts against the bottom wall of the groove of the second notch 106, thereby realizing the abutment of the positioning part 204 and the positioning mating part 108, limiting the lifting leg 10, and also ensuring that the setting of the positioning part 204 and the positioning mating part 108 does not affect the connection between the first connecting part 201 and the first connecting mating part 1011.

[0060] Optionally, the first connecting part 201 is engaged with the first connecting mating part 1011.

[0061] The first connecting portion 201 includes a first sub-connecting portion 2011, a connecting section 2012, and a guide section 2013. The first sub-connecting portion 2011 is located outside the first connecting mating portion 1011. The first sub-connecting portion 2011 abuts against the first connecting mating portion 1011, so that the first connecting portion 201 can restrict the first connecting mating portion 1011 from moving outward. The direction away from the center of the outer shell 20 is called outward, and the direction closer to the center of the outer shell 20 is called inward. The connecting segment 2012 is located between the first sub-connecting part 2011 and the guide segment 2013. Along the direction in which the first connecting mating part 1011 is inserted into the first bayonet 206, the guide segment 2013, the connecting segment 2012 and the first sub-connecting part 2011 are arranged in sequence, and the connecting segment 2012 and the guide segment 2013 are inclined towards the center of the outer shell 20. In this way, when the lifting foot 10 is assembled into the outer shell 20, the guide segment 2013 plays a guiding role, guiding the first connecting mating part 1011 to be smoothly inserted into the first bayonet 206.

[0062] Optionally, such as Figure 6 As shown, the first connecting portion 201 includes a protrusion 207 that protrudes outward from the outer shell 20 and defines a first slot 208. The direction away from the center of the outer shell 20 is called outward, and the direction closer to the center of the outer shell 20 is called inward. A first latch 206 is provided at the connection between the protrusion 207 and the outer shell 20. The first connecting mating portion 1011 includes a first buckle 109 that is inserted into the first slot 208 through the first latch 206 and engages with the first slot 208.

[0063] The first connecting portion 201 includes a protrusion 207, which is a structure protruding outward from the outer shell 20. A first sub-connecting portion 2011 defines a first slot 208, and a first latch 206 is located at the connection between the protrusion 207 and the outer shell 20. Figure 4 As shown, it is located at the connection between the guide section 2013 and the outer casing 20. When the lifting foot 10 is assembled to the outer casing 20, the first buckle 109 is inserted into the first slot 208 through the first slot 206 and engages with the first slot 208, making the connection between the lifting foot 10 and the outer casing 20 more secure.

[0064] The convex bulge 207 can increase the strength of the outer shell 20, thereby increasing the connection strength between the hanging foot 10 and the outer shell 20.

[0065] Optionally, the connection structure includes a second connection portion 202, and the connection mating structure includes a second connection mating portion 1017. The second connection portion 202 and the second connection mating portion 1017 are mated together, wherein the second connection portion 202 is disposed on the first connection portion 201.

[0066] When the lifting leg 10 is assembled onto the housing 20, the first connecting part 201 engages with the first connecting mating part 1011, and the second connecting part 202 engages with the second connecting mating part 1017. By setting multiple mating structures between the lifting leg 10 and the housing 20, the connection strength between the lifting leg 10 and the housing 20 is enhanced, and the installation reliability of the lifting leg 10 on the housing 20 is improved. Moreover, with multiple mating structures, even if one mating structure fails, other mating structures will still function, ensuring the connection strength between the lifting leg 10 and the housing 20, thereby ensuring the safety of the entire machine and enabling the machine to be used normally.

[0067] The second connecting part 202 is provided on the first connecting part 201, thus integrating the second connecting part 202 into the first connecting part 201, making the structure of the outer shell 20 more compact.

[0068] Optionally, the second connecting portion 202 includes a first screw hole 209, and the second connecting mating portion 1017 includes a second screw hole 105 corresponding to the first screw hole 209, so that the second connecting portion 202 and the second connecting mating portion 1017 are screwed together.

[0069] like Figure 2 and Figure 4 As shown, the wall of the second screw hole 105 protrudes in a direction away from the first screw hole 209 to form a flange 110, and the housing 20 is provided with a relief groove 210 for avoiding the flange 110.

[0070] The second connecting part 202 includes a first screw hole 209, and the second connecting mating part 1017 includes a second screw hole 105 corresponding to the first screw hole 209. When the lifting foot 10 is assembled on the housing 20, the first screw hole 209 and the second screw hole 105 correspond to each other. By connecting with screws, the lifting foot 10 is fixed to the housing 20. Screw fixing saves costs and provides a firm fixation.

[0071] The wall of the second screw hole 105 protrudes in the direction away from the first screw hole 209 to form a flange 110. The flange 110 increases the thickness of the screw passing through the first screw hole 209 and the second screw hole 105, thereby improving the strength of the screw connection. The housing 20 is provided with a relief groove 210 to avoid the flange 110. The relief groove 210 can prevent the flange 110 hole from scratching the housing 20.

[0072] like Figure 4 As shown, the clearance groove 210 can be formed by the outer shell 20 tilting inward, or it can be a groove that penetrates the thickness direction of the outer shell 20.

[0073] The clearance groove 210 is connected to the first bayonet 206.

[0074] Optionally, the connection structure includes a third connection part 203, and the connection mating structure includes a third connection mating part 1018. The third connection part 203 and the third connection mating part 1018 are mated, for example, by snap-fit ​​or magnetic connection, and a first gap 301 exists between the third connection part 203 and the third connection mating part 1018 in the vertical direction.

[0075] like Figure 8 As shown, the third connecting part 203 and the third connecting mating part 1018 are engaged. The outer casing 20 is provided with a third bayonet 2031. The third connecting mating part 1018 is inserted into the outer casing 20 through the third bayonet 2031 and abuts against the third connecting part 203, so that the third connecting part 203 restricts the outward movement of the lifting leg 10. The direction away from the center of the outer casing 20 is called outward, and the direction closer to the center of the outer casing 20 is called inward.

[0076] With the hanger 10 assembled on the housing 20, there is a first gap 301 between the third connecting part 203 and the third connecting mating part 1018 in the vertical direction. Even if there are machining errors between the third connecting part 203 and the third connecting mating part 1018, the positioning part 204 can still abut against the positioning mating part 108, thereby ensuring that the installation height of the multiple hangers 10 on the housing 20 is consistent.

[0077] Optionally, such as Figures 1 to 4 As shown, the hanging leg 10 includes a first plate 101 and a second plate 102.

[0078] The first plate 101 extends in the vertical direction, and the connecting structure is provided on the first plate 101; the second plate 102 is connected to the first plate 101 and the connection forms a first bend 1021.

[0079] There is a second gap 302 between the second plate 102 and the outer shell 20.

[0080] The hanging leg 10 includes a first plate 101, a second plate 102, and a third plate 103. The second plate 102 and the third plate 103 are respectively located on opposite sides of the first plate 101 and at opposite ends of the first plate 101. The second plate 102 is connected to the first plate 101 and the connection point forms a first bend 1021. The third plate 103 is connected to the first plate 101 and the connection point forms a second bend 1031. The second plate 102 bends toward the direction close to the outer shell 20, and the third plate 103 bends and extends toward the direction away from the outer shell 20.

[0081] The second plate 102 is located above the outer shell 20, and there is a second gap 302 between the second plate 102 and the outer shell 20. In this way, even if there are processing errors in the hanging feet 10 and the outer shell 20, the positioning part 204 can still abut against the positioning mating part 108, thereby ensuring that the installation height of the multiple hanging feet 10 on the outer shell 20 is consistent.
