[0049] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0051] Combination Figures 1-9 As shown, this disclosure provides a housing assembly for an indoor unit of an air conditioner, including a housing 10 and an inlet / outlet liquid enclosure 20.

[0052] The housing 10 defines an installation space, within which the indoor heat exchanger and fan of the indoor unit are located. The inlet and outlet liquid enclosure 20 is located on the housing 10 and together with the housing 10, forms a through hole through which the refrigerant pipes of the indoor heat exchanger pass.

[0053] Among them, such as Figures 5 to 9 As shown, the housing 10 is provided with a prepositioning part 101 and a connecting part, and the liquid inlet / outlet enclosure 20 is provided with a prepositioning mating part 201 and a connecting mating part. The prepositioning part 101 and the prepositioning mating part 201 cooperate, and the connecting part and the connecting mating part cooperate to restrict the liquid inlet / outlet enclosure 20 from moving in the direction away from the through hole.

[0054] When installing the inlet / outlet enclosure 20 onto the housing 10, the pre-positioning part 101 is first engaged with the pre-positioning mating part 201 to pre-position the inlet / outlet enclosure 20, and then the connecting part is engaged with the connecting mating part. Pre-positioning increases the force between the inlet / outlet enclosure 20 and the housing 10, thereby reducing the probability of the inlet / outlet enclosure 20 popping out under the action of the foam. Furthermore, it eliminates the need to manually hold the inlet / outlet enclosure 20 during assembly, allowing for screw-driving with two hands, thus improving operational efficiency and convenience.

[0055] The connection between the connecting part and the connecting mating part is used to restrict the movement of the liquid inlet / outlet enclosure 20 in the direction away from the through hole, so as to prevent the insulation foam wrapped around the refrigerant pipe from popping up the liquid inlet / outlet enclosure 20.

[0056] Optionally, such as Figure 7 As shown, one of the pre-positioning part 101 and the pre-positioning mating part 201 is a socket 102, and the other is a connector 202. The connector 202 is adapted to the socket 102 and is inserted into the socket 102.

[0057] The pre-positioning part 101 is a socket 102, and the pre-positioning mating part 201 is a connector 202, or the pre-positioning part 101 is a connector 202, and the pre-positioning mating part 201 is a socket 102.

[0058] On the one hand, the precise positioning of the liquid inlet / outlet enclosure 20 is achieved through the cooperation of the insertion hole 102 and the connecting rib 202, ensuring that the liquid inlet / outlet enclosure 20 is installed accurately on the housing 10. On the other hand, the design of the connecting rib 202 inserting into the insertion hole 102 simplifies the installation process and makes the operation more convenient.

[0059] like Figure 5 and Figure 6 As shown, the housing 10 is provided with an installation notch 103, and the inlet / outlet liquid enclosure 20 is covered by the installation notch 103. The side wall of the installation notch 103 is provided with a first folding portion 105, which includes a first folding plate 106 and a second folding plate 107. The first folding plate 106 is located on one side of the housing 10 in the thickness direction, and the second folding plate 107 is connected to the end of the first folding plate 106 away from the housing 10, and the connection point forms a bend. The second folding plate 107 is located on the side of the first folding plate 106 facing the inlet / outlet liquid enclosure 20. The inlet / outlet enclosure 20 is provided with a second folding portion 203, which includes a third folding plate 204 and a fourth folding plate 205. The third folding plate 204 is located on one side of the inlet / outlet enclosure 20 in the thickness direction. The fourth folding plate 205 is connected to the end of the third folding plate 204 away from the inlet / outlet enclosure 20, and the connection point forms a bend. The fourth folding plate 205 is located on the side of the third folding plate 204 facing the housing 10. An insertion hole 102 is provided on the first folding plate 106, and the fourth folding plate 205 forms an insertion rib 202. Alternatively, the insertion hole 102 is provided on the third folding plate 204, and the second folding plate 107 forms an insertion rib 202.

[0060] Optionally, such as Figure 6 As shown, there are multiple through holes, including a first through hole 110 and a second through hole 111, with a pre-positioning part 101 and a pre-positioning mating part 201 disposed between the first through hole 110 and the second through hole 111.

[0061] like Figure 5 As shown, the side wall of the mounting notch 103 is provided with a first notch 108 and a second notch 109, and the edge of the liquid inlet / outlet enclosure 20 is provided with a third notch 206 and a fourth notch 207. The third notch 206 and the first notch 108 are joined together to form a first through hole 110, and the fourth notch 207 and the second notch 109 are joined together to form a second through hole 111.

[0062] The refrigerant piping includes a first pipe 301 and a second pipe 302. The first pipe 301 passes through a first through hole 110, and the second pipe 302 passes through a second through hole 111. One of the first pipe 301 and the second pipe 302 serves as the refrigerant inlet pipe of the indoor heat exchanger, and the other serves as the refrigerant outlet pipe of the indoor heat exchanger.

[0063] Both the first pipe 301 and the second pipe 302 are wrapped with insulating foam, so both the first pipe 301 and the second pipe 302 exert a pushing force on the inlet / outlet liquid enclosure 20, which poses a risk of the inlet / outlet liquid enclosure 20 falling off the housing 10. The pre-positioning part 101 and the pre-positioning mating part 201 are disposed between the first through hole 110 and the second through hole 111. Specifically, the pre-positioning part 101 is located between the first notch 108 and the second notch 109, and the pre-positioning mating part 201 is located between the third notch 206 and the fourth notch 207. This allows the pre-positioning part 101 and the pre-positioning mating part 201 to be simultaneously positioned close to the first through hole 110 and the second through hole 111. This applies pressure to the insulating foam on both the first pipe 301 and the second pipe 302, preventing the foam from pushing the inlet / outlet liquid enclosure 20 out. In other words, this arrangement effectively prevents the inlet / outlet liquid enclosure 20 from being pushed out by the foam.

[0064] Optionally, such as Figure 6 and Figure 7 As shown, the connecting portion includes a first connecting portion 112, and the connecting mating portion includes a first connecting mating portion 208; the first connecting portion 112 and the first connecting mating portion 208 are connected to restrict the liquid inlet / outlet enclosure 20 from the housing 10 in a direction away from the axis of the through hole (e.g., Figure 6 (Moves along the vertical direction).

[0065] The connection between the first connecting part 112 and the first connecting mating part 208 restricts the movement of the liquid inlet / outlet enclosure 20 away from the axis of the through hole, further enhancing the stability of the liquid inlet / outlet enclosure 20 during installation.

[0066] Furthermore, by limiting the range of motion of the liquid inlet / outlet enclosure 20, errors that may occur during the installation of the liquid inlet / outlet enclosure 20 on the housing 10 are reduced.

[0067] Optionally, such as Figure 6 As shown, the first connecting part 112 and the first connecting mating part 208 are engaged.

[0068] The first connecting part 112 and the first connecting mating part 208 are connected by a snap-fit ​​method, making installation faster and requiring no additional fixing tools.

[0069] One of the first connecting part 112 and the first connecting mating part 208 is a snap fastener 209, and the other is a slot 113. For example, the first connecting mating part 208 is a snap fastener 209, and the first connecting part 112 is a slot 113. The snap fastener 209 is located at the edge of the liquid inlet / outlet enclosure.

[0070] like Figure 8As shown, the liquid inlet / outlet enclosure 20 includes first to fourth sidewalls 217. The first sidewall 214 and the second sidewall 215 are arranged opposite to each other, and the third sidewall 216 and the fourth sidewall 217 are arranged opposite to each other. The third sidewall 216 is connected between one end of the first sidewall 214 and one end of the second sidewall 215, and the fourth sidewall 217 is connected between the other end of the first sidewall 214 and the other end of the second sidewall 215.

[0071] The third notch 206 and the fourth notch 207 are both located on the second side wall 215, and the third side wall 216 and the fourth side wall 217 are both provided with the first connecting and mating part 208.

[0072] Optionally, the connecting portion includes a second connecting portion 114, and the connecting mating portion includes a second connecting mating portion 210; the second connecting portion 114 and the second connecting mating portion 210 are connected to restrict the direction of the inlet / outlet liquid enclosure 20 relative to the housing 10 along the through-hole axis (e.g., Figure 8 (Movement in a direction perpendicular to the screen).

[0073] The cooperation between the first connecting part 112 and the first connecting mating part 208, and the cooperation between the second connecting part 114 and the second connecting mating part 210, achieves comprehensive positioning of the liquid inlet / outlet enclosure 20, thereby restricting the movement of the liquid inlet / outlet enclosure 20 relative to the shell 10 under the elastic force of the foam.

[0074] Optionally, such as Figures 6 to 8 As shown, the second connecting part 210 includes a first flange 211, and the first flange 211 and the liquid inlet / outlet enclosure 20 are respectively disposed on opposite sides of the housing 10.

[0075] The first flange 211 and the inlet / outlet liquid enclosure 20 are located on both sides of the thickness direction of the housing 10. The second connecting part 114 includes the portion of the housing 10 located between the first flange 211 and the inlet / outlet liquid enclosure 20. Thus, the second connecting part 114 can restrict the movement of the inlet / outlet liquid enclosure 20 in the direction of the line connecting the first flange 211 and the inlet / outlet liquid enclosure 20, that is, restrict the movement of the inlet / outlet liquid enclosure 20 in the inward and outward directions, thereby enhancing the stability of the inlet / outlet liquid enclosure 20.

[0076] There is a gap D between the first flange 211 and the second connecting part 114 (e.g., ... Figure 7 (As shown).

[0077] The gap design between the first flange 211 and the second connecting part 114 allows for fine-tuning of the position of the inlet / outlet liquid enclosure 20 during installation, facilitating operation. The gap design also accommodates tolerances during manufacturing and installation, improving the structure's fault tolerance.

[0078] A first connecting edge 212 connects the first flange 211 and the liquid inlet / outlet enclosure 20. The first connecting edge 212 is bent between the liquid inlet / outlet enclosure 20 and the first flange 211.

[0079] The second connecting part 210 is provided on the first side wall 214.

[0080] Optionally, the second connecting part 114 includes a second flange, and the second flange and the housing 10 are respectively disposed on opposite sides of the liquid inlet / outlet enclosure 20.

[0081] The second flange and the housing 10 are located on both sides of the thickness direction of the liquid inlet / outlet enclosure 20, and the second connecting part 210 includes the part of the liquid inlet / outlet enclosure 20 located between the first flange 211 and the housing 10. Thus, the second connecting part 210 can restrict the movement of the liquid inlet / outlet enclosure 20 in the direction of the line connecting the second flange and the housing 10, that is, restrict the movement of the liquid inlet / outlet enclosure 20 in the inward and outward directions, thereby enhancing the stability of the liquid inlet / outlet enclosure 20.

[0082] There is a gap between the second flange and the second connecting mating part 210.

[0083] The gap design between the second flange and the second connecting part 210 allows for fine-tuning of the position of the inlet / outlet liquid enclosure 20 during installation, facilitating operation. The gap design also accommodates tolerances during manufacturing and installation, improving the structure's fault tolerance.

[0084] A second connecting edge connects the second flange and the housing 10. There is a bend between the second connecting edge and the housing 10, and there is also a bend between the second connecting edge and the second flange.

[0085] Optionally, such as Figure 7 and Figure 8 As shown, the connecting part also includes a first screw hole 115, and the connecting mating part also includes a second screw hole 213. The screw 40 passes through the first screw hole 115 and the second screw hole 213, and the first screw hole 115 and the second screw hole 213 are both corresponding to the first flange 211 or the second flange, so that the first flange 211 or the second flange covers the screw.

[0086] The screws pass through the first screw hole 115 and the second screw hole 213, realizing the screw connection between the liquid inlet / outlet enclosure 20 and the housing 10, which further enhances the connection strength between the liquid inlet / outlet enclosure 20 and the housing 10.

[0087] The first screw hole 115 and the second screw hole 213 are both corresponding to the first flange 211 or the second flange, so that the first flange 211 or the second flange can cover the screw, and the screw will not protrude from the first flange 211 or the second flange, thus avoiding the screw from scratching other parts.

[0088] When installing the inlet / outlet enclosure 20, insert the connector 202 into the insertion hole 102. Then, the first connecting part 112 and the first connecting mating part 208 cooperate, and the second connecting part 114 and the second connecting mating part 210 cooperate. The cooperation of the first connecting part 112 and the first connecting mating part 208 restricts the up and down movement of the inlet / outlet enclosure 20. The cooperation of the second connecting part 114 and the second connecting mating part 210 limits the front and back movement of the top of the inlet / outlet enclosure 20. At this time, the foam will not pop out the inlet / outlet enclosure 20, and the inlet / outlet enclosure 20 is limited within this range. Therefore, it is not necessary to press it with your hands. This allows for better and more convenient screw fixing. That is, the screws are inserted into the first screw hole 115 and the second screw hole 213 to complete the installation of the inlet / outlet enclosure 20.

[0089] A second aspect of this utility model provides an air conditioner, including an indoor unit. The indoor unit includes a housing assembly for an air conditioner indoor unit as described in any of the above embodiments and an indoor heat exchanger, wherein the refrigerant pipe of the indoor heat exchanger passes through a through hole.

[0090] The air conditioner provided in the second aspect of this utility model includes a housing assembly for an indoor unit of an air conditioner as described in any of the above embodiments, and therefore has all the beneficial effects of the housing assembly for an indoor unit of an air conditioner as described in any of the above embodiments, which will not be repeated here.

[0091] like Figures 1 to 4 As shown, an embodiment of the third aspect of this utility model provides a housing 10 for an indoor unit of an air conditioner, the housing 10 including a chassis 50, a side plate 60 and a hanging foot 70.

[0092] The predetermined mating part and the connecting mating part are both provided on the side plate 60. The chassis 50 includes a bottom plate, and the side plate 60 is located on the side of the bottom plate.

[0094] The first limiting part 502, the second limiting part 601 and the third limiting part 701 are connected, that is, the chassis 50, the side plate 60 and the hanging foot 70 are connected. In this way, the hanging foot 70 is not only connected to the side plate 60, but also connected to the chassis 50, thereby improving the connection strength of the hanging foot 70.

[0095] Optionally, such as Figure 4As shown, the first limiting part 502 includes a first connecting hole 503, the second limiting part 601 includes a second connecting hole 602, and the third limiting part 701 includes a third connecting hole 702. The first connecting member 801 passes through the first connecting hole 503, the second connecting hole 602, and the third connecting hole 702 to connect the first limiting part 502, the second limiting part 601, and the third limiting part 701.

[0096] The first connector 801 can be a screw or a bolt.

[0097] The design of the first connecting hole 503, the second connecting hole 602, and the third connecting hole 702, with the first connector 801 passing through these holes, further enhances the connection strength between the chassis 50, the side plate 60, and the lifting feet 70. This design makes the disassembly and maintenance of the housing 10 more convenient, facilitating later maintenance and component replacement.

[0098] Optionally, such as Figure 4 As shown, the side panel 60 includes a panel body 603 and a second folded edge 604. The panel body 603 is located on one side of the first folded edge 501; the second folded edge 604 is located on the other side of the first folded edge 501, and forms a first fold angle 605 at the connection with the panel body 603; the second limiting part 601 is located on the second folded edge 604.

[0099] The plate body 603 is located on the outer side of the first folded edge 501, and the second folded edge 604 is located on the inner side of the first folded edge 501. Alternatively, the plate body 603 is located on the inner side of the first folded edge 501, and the second folded edge 604 is located on the outer side of the first folded edge 501. The direction closer to the center of the housing 10 is considered "inner," and the direction farther from the center of the housing 10 is considered "outer." This arrangement creates a first fold angle 605 at the connection between the second folded edge 604 and the plate body 603, increasing the structural strength of the side plate 60 and enhancing its resistance to deformation.

[0100] The second limiting part 601 is provided on the second folded edge 604, which further improves the connection stability between the side plate 60 and the chassis 50 and reduces the loosening problem that may occur during the assembly of the hanger 70, the side plate 60 and the chassis 50.

[0101] like Figure 5 As shown, the second folded edge 604 is provided with a reinforcing rib 616 on the side opposite to the hanging foot 70 to enhance the strength of the second folded edge 604.

[0102] The first fold 501 can be multi-layered to enhance its strength.

[0103] Optionally, the first folded edge 501 is located between the second folded edge 604 and the hanging foot 70, or the second folded edge 604 is located between the first folded edge 501 and the hanging foot 70, such that the first folded edge 501, the second folded edge 604 and the hanging foot 70 are arranged opposite to each other, thereby realizing the "one-through-three" of the first connector 801, that is, the first connector 801 passes through the first folded edge 501, the second folded edge 604 and the hanging foot 70 at the same time.

[0104] The side plate 60 can be located on the outside or inside of the chassis 50. The hanging foot 70 is located on the outside of the chassis 50, and also on the outside of the side plate 60. The first folded edge 501 is located between the second folded edge 604 and the hanging foot 70, or the second folded edge 604 is located between the first folded edge 501 and the hanging foot 70, so that only the second folded edge 604 needs to be bent to form the first fold angle 605, and the first folded edge 501 and the hanging foot 70 do not need to be bent, thus achieving "one through three".

[0105] Optionally, such as Figure 4 and Figure 5 As shown, the side panel 60 includes a panel body 603 and a third folded edge 606. One end of the third folded edge 606 forms a second fold angle 607 at the connection between it and the panel body 603. The other end of the third folded edge 606 has a first insertion gap 609 between it and the panel body 603, so that the third folded edge 606 and the panel body 603 together enclose a limiting space 608. The hanging foot 70 is provided with a limiting rib 703, which is inserted into the limiting space 608 through the first insertion gap 609 and abuts against the third folded edge 606.

[0106] The presence of the second fold angle 607 causes the third fold edge 606 and the plate body 603 to jointly enclose a limiting space 608. The limiting rib 703 is inserted into the limiting space 608 through the first insertion gap 609 and abuts against the inner wall surface of the third fold edge 606 to restrict the inward movement of the side plate 60. One end of the limiting rib 703 is connected to the hanging foot 70, and there is a second insertion gap 704 between the other end of the limiting rib 703 and the hanging foot 70. The third fold edge 606 extends outward through the second insertion gap 704 to restrict the movement of the enclosure plate in the inward and outward directions. The direction closer to the middle of the shell 10 is inward, and the direction farther from the middle of the shell 10 is outward.

[0107] Optionally, the chassis 50 is provided with a positioning part, and the side plate 60 is provided with a positioning mating part. The positioning part and the positioning mating part cooperate to restrict the movement of the side plate 60 relative to the chassis 50.

[0108] The positioning part on the chassis 50 engages with the positioning mating part on the side plate 60, restricting the movement of the side plate 60 relative to the chassis 50 and ensuring accurate positioning of the side plate 60 during installation. This design reduces potential misalignment problems during the assembly of the enclosure, chassis 50, and lifting feet 70, improving assembly accuracy and efficiency.

[0109] Optionally, such as Figure 5 and Figure 9 As shown, one of the positioning part and the positioning mating part includes a first locking protrusion 610 and the other includes a first locking hole, and the first locking protrusion 610 engages with the first locking hole; wherein, the second limiting part 601 is provided on the first plate wall 611 of the side plate 60, the positioning mating part is located on the second plate wall 612 of the side plate 60, and a bend is formed at the connection between the first plate wall 611 and the second plate wall 612.

[0110] The snap-fit ​​design of the first snap protrusion 610 and the first snap hole further enhances the connection stability between the chassis 50 and the side plate 60, reducing the loosening problems that may occur during assembly.

[0111] The side panel 60 also includes a third wall 613, which is disposed opposite to the first wall 611. There are two second walls 612, which are disposed opposite to each other. One second wall 612 is connected between one end of the first wall 611 and one end of the third wall 613, and the other second wall 612 is connected between the other end of the first wall 611 and the other end of the third wall 613.

[0112] The second limiting part 601 is provided on the first plate wall 611 of the side plate 60, and the positioning and mating part is located on the second plate wall 612. In this way, the second limiting part 601 and the positioning and mating part are not located on the same plate wall, so that there is a connection structure between each plate wall of the side plate 60 and the chassis 50.

[0113] The chassis 50 is also provided with a fourth folded edge, which corresponds to the second plate wall 612 and is located on the inner or outer side of the second plate wall 612. The positioning part is provided on the fourth folded edge.

[0114] Optionally, such as Figure 2 , Figure 5 and Figure 9 As shown, the positioning part includes a fourth connecting hole, and the positioning mating part includes a fifth connecting hole 615. The second connecting member 802 passes through the fourth connecting hole and the fifth connecting hole 615 to connect the positioning part and the positioning mating part. The second limiting part 601 is provided on the first plate wall 611 of the side plate 60, and the positioning mating part is located on the second plate wall 612 of the side plate 60. A bend is formed at the connection between the first plate wall 611 and the second plate wall 612.

[0115] The design of the fourth and fifth connecting holes 615, through which a second connector 802 (such as a bolt or screw) passes through the fourth and fifth connecting holes 615, further enhances the connection strength between the chassis 50 and the side plate 60.

[0116] The second limiting part 601 is provided on the first plate wall 611 of the side plate 60, and the positioning and mating part is located on the second plate wall 612. In this way, the second limiting part 601 and the positioning and mating part are not located on the same plate wall, so that there is a connection structure between each plate wall of the side plate 60 and the chassis 50.

[0117] The first protrusion 610 and the fifth connecting hole 615 are arranged sequentially along the length of the second plate wall 612.

[0118] Optionally, such as Figure 9 As shown, the housing 10 also includes a reinforcing plate 90, which is disposed on the side plate 60 and riveted to the side plate 60 by a TOX riveting process.

[0119] TOX riveting is a cold-forming joining process that eliminates rivets and welding. It uses mold pressure to cause plastic deformation in localized areas of two or more metal sheets, forming a strong mechanical connection. The reinforcing plate 90 is connected to the side plate 60 using TOX riveting, avoiding the aesthetic defects associated with traditional welding processes and improving the appearance of the housing 10.

[0120] The TOX riveting process enhances the connection strength between the reinforcing plate 90 and the side plate 60, ensuring the overall structural stability of the housing 10.

[0121] A reinforcing plate 90 is disposed on the inner side of the side plate 60 to enhance the strength of the side plate 60. The reinforcing plate 90 is disposed at the first through hole 110 and the second through hole 111, and is provided with a fifth notch 901 and a sixth notch 902. The fifth notch 901 overlaps with the first notch 108, and the sixth notch 902 overlaps with the second notch 109, so as to enhance the strength of the side plate 60 at the first through hole 110 and the second through hole 111.
