[0061] 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.

[0062] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0063] Combination Figures 1-13 As shown, this embodiment of the present disclosure provides an indoor unit, including: a housing 30, a water receiving tray 20, and a hanging foot 10.

[0064] like Figures 11 to 13 As shown, the water receiving tray 20 is provided on the housing 30 and has a connecting part 204; the hanging foot 10 is provided on the housing 30 and has a connecting mating part 104 for connecting with the connecting part 204.

[0065] Among them, such as Figures 5 to 8 As shown, the water receiving tray 20 is provided with a positioning part 201, and the hanging foot 10 is provided with a positioning mating part 102. The positioning part 201 and the positioning mating part 102 cooperate to realize the positioning of the water receiving tray 20 relative to the hanging foot 10.

[0066] By providing a positioning part 201 on the water receiving tray 20 and a positioning mating part 102 on the lifting foot 10, and by engaging the positioning part 201 and the positioning mating part 102, accurate positioning of the water receiving tray 20 relative to the lifting foot 10 can be achieved. This effectively solves the problem of misalignment between the water receiving tray 20 and the lifting foot 10 in the prior art, and improves the assembly efficiency and reliability between the water receiving tray 20 and the lifting foot 10.

[0067] After the water receiving tray 20 and the lifting foot 10 are positioned by the positioning part 201 and the positioning mating part 102, the connecting part 204 and the connecting mating part 104 are connected to realize the connection between the lifting foot 10 and the water receiving tray 20. The lifting foot 10 is provided on the housing 30, so the water receiving tray 20 is installed on the housing 30 by means of the lifting foot 10.

[0068] Optionally, such as Figure 8 As shown, one of the positioning part 201 and the positioning mating part 102 includes a positioning protrusion 103, and the other includes a positioning groove 202, with the positioning protrusion 103 inserted into the positioning groove 202.

[0069] The positioning part 201 includes a positioning protrusion 103, and the positioning mating part 102 includes a positioning groove 202; alternatively, the positioning part 201 includes a positioning groove 202, and the positioning mating part 102 includes a positioning protrusion 103. The positioning protrusion 103 is adapted to the positioning groove 202.

[0070] The positioning protrusion 103 is inserted into the positioning groove 202, which can ensure that the water receiving tray 20 and the hanging foot 10 are quickly and accurately aligned during the assembly process, effectively preventing the water receiving tray 20 from shifting position during the assembly process, and improving the accuracy and stability of the assembly.

[0071] like Figure 1 As shown, the surface of the positioning protrusion 103 is provided with a guide slope 1031. Along the direction in which the positioning protrusion 103 is inserted into the positioning groove 202, the guide slope 1031 is inclined toward the middle of the positioning protrusion 103.

[0072] Optionally, such as Figure 1 As shown, the sling 10 includes a script body 106 and an extension plate 101.

[0073] The script body 106 is disposed on the housing 30; the extension plate 101 is disposed on one side of the script body 106 and is bent at the connection with the script body 106, for example, forming a 90° bend; wherein, the positioning mating part 102 is disposed on the extension plate 101.

[0074] The lifting foot 10 is designed to include a base 106 and an extension plate 101, with the positioning and mating part 102 located on the extension plate 101 and the base 106 located on the housing 30. This structural design organically integrates the positioning function of the lifting foot 10 with the overall structure, ensuring that the placement of the positioning and mating part 102 does not affect the fit between the base 106 and the housing 30. Furthermore, the bending design of the extension plate 101 and the base 106 increases the structural strength and stability of the lifting foot 10, while providing a suitable position for the positioning and mating part 102, allowing it to better fit with the positioning part 201 on the water receiving tray 20.

[0075] Optionally, such as Figure 6 As shown, the script body 106 is located on the outside of the housing 30, the extension plate 101 is located on the inside of the script body 106, the opening end 301 of the housing 30 is provided with a first clearance groove 302, and the extension plate 101 is located in the first clearance groove 302.

[0076] The support body 106 is located on the outside of the housing 30, and the extension plate 101 is located on the inside of the support body 106. The opening end 301 of the housing 30 has a first clearance groove 302. The extension plate 101 extends into the housing 30 through the first clearance groove 302, so that the positioning mating part 102 on the extension plate 101 mates with the positioning part 201 of the water receiving tray 20. This design makes the assembly between the lifting foot 10 and the housing 30 more compact and reasonable, reducing space occupation and improving the overall aesthetics and space utilization of the product. At the same time, the first clearance groove 302 provides clearance space for the extension plate 101, avoiding possible interference between the lifting foot 10 and the housing 30 during assembly, further improving the smoothness and reliability of assembly, and ensuring the stability and safety of the product in actual use.

[0077] The first clearance groove 302 has a groove wall comprising a first groove wall 303, a second groove wall 304, and a third groove wall 305. The second groove wall 304 and the third groove wall 305 are respectively located on opposite sides of the first groove wall 303, and both the connection points between the second groove wall 304 and the first groove wall 303 and the third groove wall 305 and the first groove wall 303 have bends. Along a direction away from the first groove wall 303, the second groove wall 304 and the third groove wall 305 are inclined away from the center of the first clearance groove 302, forming an inclined structure to guide the extension plate 101 into the first clearance groove 302.

[0078] Optionally, such as Figure 6 As shown, the edge of the connection between the extension plate 101 and the script body 106 is provided with a second clearance groove 105 for avoiding the housing 30.

[0079] The inclined structures of the second groove wall 304 and the third groove wall 305 not only guide the extension plate 101 to smoothly insert into the first clearance groove 302, but also enhance the strength of the first clearance groove 302, preventing the housing 30 from being too weak at the first clearance groove 302. A second clearance groove 105 is provided at the edge of the connection between the extension plate 101 and the base body 106 to avoid the housing 30, specifically to avoid the second groove wall 304 and the third groove wall 305, ensuring that the inclined structures of the second groove wall 304 and the third groove wall 305 do not affect the insertion of the extension plate 101 into the second clearance groove 105.

[0080] The two sides of the connection between the extension plate 101 and the script body 106 are provided with second clearance grooves 105 to avoid the second groove wall 304 and the third groove wall 305 respectively.

[0081] Optionally, such as Figure 6 As shown, the width of the extension plate 101 (along...) Figure 6 The width of the text (in the left and right directions) is less than the width of the script body (106).

[0082] The width of the extension plate 101 is smaller than the width of the script body 106, which makes the size of the first clearance groove 302 smaller, thereby reducing the reduction in the strength of the housing 30 caused by the setting of the first clearance groove 302. At the same time, the smaller width of the extension plate 101 also helps to reduce the material cost of the hanger 10, without affecting the fit between the positioning part 201 and the positioning mating part 102.

[0083] Optionally, such as Figure 4 and Figure 6 As shown, the water receiving tray 20 is provided with a third clearance groove 203, and the extension plate 101 is provided in the third clearance groove 203.

[0084] The water receiving tray 20 is provided with a third clearance groove 203, and the extension plate 101 is located in the third clearance groove 203. This design further optimizes the assembly relationship between the water receiving tray 20 and the hanging foot 10. The third clearance groove 203 provides clearance space for the extension plate 101, ensuring that the extension plate 101 and the water receiving tray 20 can fit tightly without interference.

[0085] The water receiving tray 20 is inserted into the housing 30 through the open end 301. A third clearance groove 203 is provided on the surface of the water receiving tray 20 facing the bottom wall of the housing 30, wherein the bottom wall of the housing 30 is positioned opposite the open end 301. During assembly, the lifting foot 10 is first assembled with the housing 30, the extension plate 101 is inserted into the first clearance groove 302, and then the water receiving tray 20 is placed over the open end 301 of the housing 30. Due to the presence of the third clearance groove 203, the water receiving tray 20 will not interfere with the lifting foot 10 during the insertion into the housing 30.

[0086] Optionally, such as Figure 1 As shown, there are multiple positioning parts 201, and a connecting part 204 is disposed between the multiple positioning parts 201.

[0087] By increasing the number of positioning parts 201, the positioning accuracy and stability between the water receiving tray 20 and the lifting foot 10 are further improved. The number of positioning mating parts 102 is equal to the number of positioning parts 201 and corresponds one-to-one. Multiple positioning parts 201 can simultaneously engage with the positioning mating parts 102 on the lifting foot 10, ensuring that the water receiving tray 20 can be accurately positioned at all points, thereby effectively preventing the water receiving tray 20 from shifting position during assembly.

[0088] Meanwhile, the connecting part 204 is disposed among multiple positioning parts 201, making the relative position between the connecting part 204 and the connecting mating part 104 more accurate, thereby facilitating the connection between the connecting part 204 and the connecting mating part 104.

[0089] Optionally, such as Figure 8As shown, the connecting part 204 includes a first screw hole 205, and the connecting mating part 104 includes a second screw hole 105. The first screw hole 205 and the second screw hole 105 are connected by screws, wherein one of the first screw hole 205 and the second screw hole 105 is an elongated hole.

[0090] The connecting part 204 includes a first screw hole 205, and the connecting mating part 104 includes a second screw hole 105, one of which is an elongated hole. A screw passes through the first screw hole 205 and the second screw hole 105 to achieve a screw connection between the connecting part 204 and the connecting mating part 104.

[0091] One of the first screw hole 205 and the second screw hole 105 is an elongated hole, and the other is a round hole. For example, if the first screw hole 205 is an elongated hole and the second screw hole 105 is a round hole, the connection between the first screw hole 205 and the second screw hole 105 has a certain adjustment margin, which can effectively compensate for the hole position deviation between the first screw hole 205 and the second screw hole 105 caused by machining errors or assembly errors. The design of the elongated hole allows the screw to be adjusted within a certain range, thereby ensuring that the screw can pass smoothly through the first screw hole 205 and the second screw hole 105 and achieve connection, improving the fault tolerance and flexibility of assembly.

[0092] The connecting part 204 and the connecting mating part 104 can also be snap-fitted or connected in other ways.

[0093] like Figure 13 As shown, the script body 106 is provided with a first buckle 107 and a second buckle 109. A first insertion port 108 exists between the first buckle 107 and the script body 106, and a second insertion port 110 exists between the second buckle 109 and the script body 106. The housing 30 is provided with a third insertion port 306 corresponding to the first buckle 107. The first buckle 107 is inserted through the third insertion port 306 and abuts against the inner wall surface of the housing 30. The housing 30 is provided with an outwardly protruding convex 307 corresponding to the second buckle 109 to enhance the strength of the housing 30. A fourth insertion port 308 is formed at the connection between the convex convex 307 and the housing 30. The second buckle 109 is inserted into the housing 30 through the fourth insertion port 308 and abuts against the inner wall surface of the housing 30. The second buckle 109 and the convex convex 307 are connected, for example, by screws.

[0094] A second aspect of the present invention provides an air conditioner, comprising: an indoor unit as described in any one of the embodiments of the first aspect.

[0095] The air conditioner provided in the second aspect of this utility model includes an indoor unit as described in any of the above embodiments, and therefore has all the beneficial effects of an indoor unit as described in any of the above embodiments, which will not be repeated here.

[0096] like Figures 14 to 19 As shown, an embodiment of the third aspect of this utility model provides a housing, including a main body 40 and an inlet / outlet liquid enclosure 50.

[0097] The main body 40 has an installation notch; the inlet / outlet liquid enclosure 50 covers the installation notch. The main body 40 and the inlet / outlet liquid enclosure form a through hole. The housing is used in the indoor unit of the air conditioner. The indoor unit also includes an indoor heat exchanger, which is located inside the housing, and the refrigerant pipes of the indoor heat exchanger pass through the through hole and exit the housing.

[0098] The indoor unit also includes a fan. Both the indoor heat exchanger and the fan are housed within the casing, which has an air inlet and an air outlet. Under the action of the fan, air enters through the air inlet, exchanges heat with the indoor heat exchanger, and is then blown out from the air outlet.

[0099] The main body 40 is provided with a connecting structure, and the inlet / outlet liquid enclosure 50 is provided with a connecting fit structure that cooperates with the connecting structure so that the main body 40 and the inlet / outlet liquid enclosure 50 are connected; wherein, the main body 40 is provided with a positioning structure, and the inlet / outlet liquid enclosure 50 is provided with a positioning fit structure, and the positioning structure and the positioning fit structure cooperate so that the connecting structure and the connecting fit structure correspond to each other.

[0100] By setting a positioning structure on the main body 40 and a positioning mating structure on the inlet / outlet liquid enclosure 50, the main body 40 and the inlet / outlet liquid enclosure 50 can be quickly and accurately pre-positioned before connection. This pre-positioning method ensures that the connecting structure and the connecting mating structure correspond accurately, thus eliminating the need for manual alignment when connecting the main body 40 and the inlet / outlet liquid enclosure 50 using the connecting structure and the connecting mating structure. This effectively improves assembly efficiency, reduces assembly errors and safety hazards caused by inaccurate alignment of the connecting structure and the connecting mating structure, and enhances the overall quality and reliability of the product.

[0101] Optionally, such as Figure 15 and Figure 19 As shown, the positioning structure includes a first sub-positioning structure 403, and the positioning mating structure includes a first sub-positioning mating structure 503. The first sub-positioning structure 403 and the first sub-positioning mating structure 503 mate with each other, and the first sub-positioning structure 403 and / or the first sub-positioning mating structure 503 are provided with a self-locking structure.

[0102] A self-locking structure is provided in the first sub-positioning structure 403 and / or the first sub-positioning mating structure 503, which further improves the connection stability between the liquid inlet / outlet enclosure 50 and the main body 40. Compared with the structure in related technologies that only rely on the engagement of the slot and the locking strip, the self-locking structure can automatically lock after the main body 40 and the liquid inlet / outlet enclosure 50 are pre-positioned, preventing the liquid inlet / outlet enclosure 50 from accidentally coming off due to external force or vibration.

[0103] Optionally, such as Figure 15and Figure 19 As shown, one of the first sub-positioning structure 403 and the first sub-positioning mating structure 503 includes a first protrusion 504, and the other includes a first groove 404. The first protrusion 504 is inserted into the first groove 404, and the first protrusion 504 and / or the first groove 404 are provided with a self-locking structure.

[0104] The first protrusion 504 is adapted to the first groove 404, and the engagement of the first protrusion 504 and the first groove 404 enables rapid positioning between the main body 40 and the inlet / outlet liquid enclosure 50. Compared with related technologies, this application further enhances the stability of the first protrusion 504 and the first groove 404 after positioning by providing a self-locking structure on the first protrusion 504 and / or the first groove 404. This structural design not only improves assembly efficiency but also reduces assembly errors caused by inaccurate positioning, while simplifying the assembly process, reducing production costs, and improving the overall performance and market competitiveness of the product.

[0105] Optionally, such as Figure 15 and Figure 19 As shown, the first protrusion 504 includes a first end 505 and a second end 506. The first end 505 and the second end 506 are arranged sequentially along the direction in which the first protrusion 504 is inserted into the first groove 404. The height of the first end 505 is less than the height of the second end 506 to form a self-locking structure.

[0106] By designing the first protrusion 504 such that the height of the first end 505 is less than the height of the second end 506, a ratchet-like self-locking characteristic is formed. This design allows the first protrusion 504 to automatically lock after being inserted into the first groove 404, preventing it from coming out due to external force.

[0107] The height of the first end 505 gradually decreases from the height of the second end 506, achieving a smooth transition from the first end 505 to the second end 506, which facilitates the insertion of the first protrusion 504 into the first groove 404.

[0108] There is a height difference between the first end 505 and the second end 506, and the height of the first end 505 is less than the height of the second end 506. On the one hand, when the first protrusion 504 is inserted into the first groove 404, this setting can play a guiding role, guiding the first protrusion 504 to smoothly insert into the first groove 404. On the other hand, after the first protrusion 504 is inserted into the first groove 404, the second end 506 protrudes out of the first groove 404. Taking the first protrusion 504 as an example that is provided on the inlet / outlet liquid enclosure 50, the second end 506 protrudes inward from the first groove 404, so that the second end 506 plays a self-locking role, preventing the first protrusion 504 from coming out of the first groove 404.

[0109] The outer wall surface of the first protrusion 504 includes a first outer wall surface 507 and a second outer wall surface 508. The first outer wall surface 507 is connected between the first end 505 and the second end 506. The second outer wall surface 508 is connected between the first end 505 and the second end 506 and is disposed opposite to the first outer wall surface 507. The first outer wall surface 507 and / or the second outer wall surface 508 include an inclined surface that is inclined toward the middle of the first protrusion 504 along the direction in which the first protrusion 504 is inserted into the first groove 404.

[0110] like Figure 15 and Figure 19 As shown, the outer wall surface of the first protrusion 504 also includes a third outer wall surface 509. The third outer wall surface 509 is connected between the first outer wall surface 507, the second outer wall surface 508, the first end 505, and the second end 506. From the first end 505 to the second end 506, the height of the third outer wall surface 509 gradually increases, so that the height of the first end 505 is less than the height of the second end 506, and from the first end 505 to the second end 506, the height of the first protrusion 504 gradually increases.

[0111] Besides the height difference between the first end 505 and the second end 506, the self-locking structure can also take other forms. For example, one of the first sub-positioning structure 403 and the first sub-positioning mating structure 503 is an elastic buckle, and the other is a locking hole, with the elastic buckle inserted into the locking hole. An elastic buckle is a mechanical structure that achieves self-locking through elastic deformation. It typically consists of an elastic arm and a buckle head, with the buckle head designed to have a certain bevel and vertical shape.

[0112] Elastic arms are typically made of materials with a certain degree of elasticity, such as plastic or metal spring sheets. They are capable of elastic deformation under external force and return to their original shape after the force is removed. The latching head is located at the end of the elastic arm and is designed as a protrusion with both a bevel and a vertical surface. The bevel guides the latching head into the latching hole, while the vertical surface provides a locking function once the latch is in place.

[0113] When the elastic buckle is assembled with the locking hole, the beveled surface of the buckle head contacts the surface of the locking hole. As assembly progresses, the buckle head gradually enters the locking hole along the beveled surface, during which the elastic arm is compressed or bent, resulting in elastic deformation. Once the buckle head is fully inserted into the locking hole, the elastic arm returns to its original shape, and the vertical surface of the buckle head fits tightly against the inner wall of the locking hole, thus achieving locking.

[0114] The vertical surface of the latch head makes close contact with the inner wall of the latch hole, generating significant friction to prevent the latch head from disengaging without external force. Due to the elastic properties of the elastic arm, even under certain external force, the latch head is not easily disengaged from the latch hole, thus achieving a self-locking function.

[0115] Optionally, such as Figures 17 to 19 As shown, the connection structure includes a first sub-connection structure, the connection mating structure includes a first sub-connection mating structure 514, and the first sub-connection structure is connected to the first sub-connection mating structure 514; the positioning structure includes a first sub-positioning structure 403, the positioning mating structure includes a first sub-positioning mating structure 503, and the first sub-positioning structure 403 is mated with the first sub-positioning mating structure 503.

[0116] The first sub-connecting mating structure 514 and the first sub-positioning mating structure 503 are located on the same side of the inlet / outlet liquid enclosure 50.

[0117] The first sub-connecting mating structure 514 and the first sub-positioning mating structure 503 are located on the same side of the inlet and outlet liquid enclosure 50, so that the first sub-connecting mating structure 514 and the first sub-positioning mating structure 503 are closer together. Therefore, after the first sub-positioning mating structure 503 and the first sub-positioning structure 403 are engaged, the first sub-connecting mating structure 514 can more easily reach the preset position. In the preset position, the first sub-connecting mating structure 514 and the first sub-connecting structure can be better aligned.

[0118] Optionally, such as Figure 14 and Figure 16 As shown, the connection structure includes a second sub-connection structure 415, the connection mating structure includes a second sub-connection mating structure 515, the second sub-connection structure 415 is connected to the second sub-connection mating structure 515, the positioning structure includes a second sub-positioning structure 410, the positioning mating structure includes a second sub-positioning mating structure 510, the second sub-positioning structure 410 is mated to the second sub-positioning mating structure 510.

[0119] The liquid inlet / outlet enclosure 50 includes an enclosure body 513 and a connecting plate 512. The enclosure body 40 covers the installation notch; the connecting plate 512 is located on one side of the enclosure body 513.

[0120] The second sub-positioning mating structure 510 and the second sub-connecting mating structure 515 are both located on the connecting plate 512.

[0121] By setting a connecting plate 512 on the inlet / outlet liquid containment plate 50, and placing both the second sub-positioning mating structure 510 and the second sub-connecting mating structure 515 on the connecting plate 512, the structure of the inlet / outlet liquid containment plate 50 becomes more compact and its functions more concentrated. Because the second sub-positioning mating structure 510 and the second sub-connecting mating structure 515 are closer together, the engagement of the second sub-positioning structure 410 with the second sub-positioning mating structure 510 can directly guide the alignment of the second sub-connecting structure 415 and the second sub-connecting mating structure 515, reducing the accumulation of errors caused by excessive distance. This ensures precise alignment of the second sub-connecting structure 415 and the second sub-connecting mating structure 515, thereby improving the overall assembly accuracy.

[0122] Optionally, such as Figure 14 and Figure 16 As shown, one of the second sub-positioning structure 410 and the second sub-positioning mating structure 510 includes a second protrusion 511, and the other includes a second groove 411, with the second protrusion 511 inserted into the second groove 411.

[0123] The second protrusion 511 and the second groove 411 are used as the second sub-positioning structure 410 and the second sub-positioning mating structure 510, which further enhances the positioning accuracy and stability between the liquid inlet / outlet enclosure 50 and the main body 40. Compared with the prior art, this structure is simple and easy to manufacture, enabling rapid positioning while ensuring positioning accuracy and reliability. By setting multiple sets of positioning structures at different positions of the liquid inlet / outlet enclosure 50, the present invention further improves the stability and reliability of the entire assembly structure and reduces the risk of assembly errors and product failures caused by inaccurate positioning.

[0124] Taking the second protrusion 511 provided on the connecting plate 512 as an example, the edge of the connecting plate 512 protrudes towards the shell to form the second protrusion 511.

[0125] Optionally, such as Figure 14 and Figure 15 As shown, the positioning structure includes a first sub-positioning structure 403 and a second sub-positioning structure 410, and the positioning mating structure includes a first sub-positioning mating structure 503 and a second sub-positioning mating structure 510. The first sub-positioning structure 403 mates with the first sub-positioning mating structure 503, and the second sub-positioning structure 410 mates with the second sub-positioning mating structure 510.

[0126] The first sub-positioning mating structure 503 and the second sub-positioning mating structure 510 are located on opposite sides of the inlet / outlet liquid enclosure 50.

[0127] By setting a first sub-positioning mating structure 503 and a second sub-positioning mating structure 510 on opposite sides of the inlet / outlet liquid enclosure 50, accurate positioning of the inlet / outlet liquid enclosure 50 can be achieved on both opposite sides. This design further improves the positioning accuracy and stability between the inlet / outlet liquid enclosure 50 and the main body 40, ensuring that the connecting structure and the connecting mating structure can accurately correspond.

[0128] Both the connecting structure and the connecting mating structure can be screw holes, and the two can be connected by screws; or, the connecting structure and the connecting mating structure can also be in the form of a snap-fit.

[0129] The positioning structure and positioning mating structure can also adopt a magnetic positioning structure. For example, a magnetic element (such as a magnet or magnetic material) is set on the main body 40, and a magnetic mating element (such as a ferromagnetic material or another magnet) that mates with the magnetic element is set on the inlet / outlet liquid enclosure 50.

[0130] When assembling the inlet / outlet liquid enclosure 50 onto the main body 40, first insert the second protrusion 511 into the second groove 411, then rotate the inlet / outlet liquid enclosure 50 in the following direction: Figure 17 As shown by the middle arrow, the first protrusion 504 is inserted into the first groove 404, and then the connecting structure and the connecting mating structure are connected to realize the installation of the liquid inlet / outlet enclosure 50 on the main body 40.

[0131] like Figures 14 to 17 As shown, the liquid inlet / outlet enclosure 50 has a first notch 501 and a second notch 502, and the main body 40 has a third notch 401 and a fourth notch 402. The third notch 401 and the first notch 501 are joined together to form a first through hole 601, and the fourth notch 402 and the second notch 502 are joined together to form a second through hole 602. The refrigerant pipeline includes a first refrigerant pipeline and a second refrigerant pipeline, and the through holes include the first through hole 601 and the second through hole 602. The first refrigerant pipeline passes through the first through hole 601, and the second refrigerant pipeline passes through the second through hole 602. The connecting plate 512 is located on the same side of the liquid inlet / outlet enclosure 50 as the first notch 501 and the second notch 502.

[0132] like Figure 14 As shown, the inlet / outlet liquid enclosure 50 is provided with a wire-passing opening 516, which penetrates the side wall of the inlet / outlet liquid enclosure 50, and there is an angle between the side wall where the wire-passing opening 516 is located and the side wall where the connecting plate 512 is located. The wire-passing opening 516 penetrates the edge of the side wall where it is located, and the opening of the wire-passing opening 516 forms a constricted structure, through which the wire inside the housing exits the housing. The wire extends into the wire-passing opening 516 through the opening of the wire-passing opening 516, and the constricted structure prevents the wire from coming out of the wire-passing opening 516.

[0133] Optionally, such as Figure 14As shown, the housing also includes a gasket 70, which is disposed on the surface of the inlet / outlet liquid enclosure 50. The gasket 70 is provided with a clearance notch 701 for avoiding the connection and mating structure.

[0134] The gasket 70 has the functions of heat preservation and anti-condensation. Taking the connection structure and the connecting mating structure as an example, the gasket 70 is provided on the surface of the liquid inlet / outlet enclosure 50, and the gasket 70 is provided with a clearance notch 701 to avoid the connecting mating structure, which can effectively prevent the screw from damaging the gasket 70 during the assembly process.

[0135] The clearance notch 701 is arc-shaped, such as semi-circular, to avoid the connection and mating structure.

[0136] like Figure 14 As shown, the pad 70 is provided on the enclosure body 513, the first sub-connecting structure 514 is provided on the connecting plate 512, the second sub-connecting structure 515 is provided on the enclosure body 513, and the pad 70 is provided with a clearance notch 701 for avoiding the second sub-connecting structure 515.

[0137] The enclosure body 513 is provided with an outwardly protruding bulge 517, and an operating space 518 is formed between the bulge 517 and the enclosure body 513. The head of tools such as wrenches can be inserted into the operating space 518, and the wrench can be turned to lift up the liquid inlet / outlet enclosure 50.

[0138] The outer wall surface of the opening end of the shell is provided with reinforcing ribs 80, which extend around the circumference of the shell.

[0139] like Figure 22 and Figure 23 As shown, the reinforcing ribs include a first rib segment, a second rib segment, and a transition rib segment.

[0140] The first end of the second reinforcement segment is connected to the first end of the first reinforcement segment, and the width of the second reinforcement segment is greater than the width of the first reinforcement segment; the transition reinforcement segment is connected between the second end of the second reinforcement segment and the second end of the first reinforcement segment; wherein, along the direction from the first reinforcement segment to the second reinforcement segment, the width of the transition reinforcement segment gradually increases.

[0141] In this embodiment of the present disclosure, when the widths of the two rib segments are different, a transition rib segment 805 is provided between the two rib segments. The width of the transition rib segment 805 gradually increases from the narrower first rib segment 803 to the wider second rib segment 804. In this way, the width of the transition rib segment 805 gradually changes, so that the first rib segment 803 and the second rib segment 804 are another continuous reinforcing rib 80, and the width and position of the first rib segment 803 and the second rib segment 804 are consistent from the appearance.

[0142] The lifting feet correspond to the transition rib sections so that they can conceal the transition rib sections after being installed on the shell. This concealment ensures that the width of the overall reinforcing ribs on the shell is more consistent, avoiding an abrupt visual effect.

[0143] like Figure 20 and Figure 21 As shown, the housing body includes multiple housing segments, including a first housing segment 801 and a second housing segment 802.

[0144] The first shell segment is provided with a first reinforcing rib; the first end of the second shell segment is connected to the first end of the first shell segment, and the second shell segment is provided with a second reinforcing rib; wherein, when the first shell segment and the second shell segment are connected, the first end of the second shell segment abuts against the outside of the first end of the first shell segment, and the second reinforcing rib is sleeved on the outside of the first reinforcing rib. The reinforcing rib includes both the first reinforcing rib and the second reinforcing rib.

[0145] The water receiving tray has a hook structure, and when the water receiving tray is located inside the housing, the hook engages with the housing; and / or, the water receiving tray has a first screw hole, and the housing has a second screw hole, and fasteners pass through the first screw hole and the second screw hole to achieve screw connection between the water receiving tray and the housing.
