[0070] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0071] The following is for reference. Figures 1-25 Description of housing assembly 100 according to an embodiment of the present utility model.

[0072] Reference Figure 1 , Figure 2 and Figure 4 According to a first aspect embodiment of the present invention, the housing assembly 100 includes a front housing component 10 and a rear housing component 20. The front housing component 10 includes a detachably connected air outlet frame assembly 11 and a front housing 13. The air outlet frame assembly 11 forms an air outlet 111 and is mounted on the front housing 13. The air outlet frame assembly 11 is provided with a first connecting structure 112, and the front housing 13 is provided with a second connecting structure 132. The first connecting structure 112 and the second connecting structure 132 are detachably connected and together form at least one closed shape. The rear housing component 20 is connected to the rear side of the front housing component 10 and forms an air inlet 21.

[0073] For example, air conditioner 1000 is a split-type floor-standing air conditioner 1000. Air conditioner 1000 includes an indoor unit and an outdoor unit. The indoor unit includes a casing assembly 100 and a heat exchange and air supply assembly 600. The heat exchange and air supply assembly 600 is disposed inside the casing assembly 100. The casing assembly 100 includes a front shell component 10 and a rear shell component 20. The front shell component 10 includes an air outlet frame assembly 11 and a front shell 13. The air outlet frame assembly 11 forms an air outlet. 111. The rear housing component 20 is connected to the rear side of the front housing component 10 and the rear housing component 20 forms an air inlet 21. The heat exchange and air supply assembly 600 is disposed between the air inlet 21 and the air outlet 111. When the indoor unit of the air conditioner is working, the airflow enters the housing component 100 through the air inlet 21 and flows to the heat exchange and air supply assembly 600. The air after heat exchange by the heat exchange and air supply assembly 600 can be blown out to the room through the air outlet 111 to heat or cool the room.

[0074] The first connecting mechanism on the air outlet frame assembly 11 is detachably connected to the second connecting structure 132 on the front shell 13, which enables a detachable connection between the air outlet frame assembly 11 and the front shell 13, thereby facilitating the maintenance or replacement of the air outlet frame assembly 11 or the front shell 13.

[0075] The first connecting structure 112 and the second connecting structure 132 jointly enclose at least one closed figure. When the shell assembly 100 is subjected to external force, for example, collision, extrusion or vibration, due to the high stability of the closed figure, the connection mode of the closed figure can form a stable structure that supports and restricts each other between the air outlet frame assembly 11 and the front shell 13. For example, when a certain part is subjected to external force, the adjacent part can provide support and constraint to the part in time through the connection relationship of the closed figure. In this way, the external force on the shell assembly 100 can be evenly dispersed to the entire connection area, avoiding the concentration of external force on a certain point or line. The entire closed figure can jointly resist the external force, reducing the local deformation of the air outlet frame or the front shell 13, effectively resisting the external force or the vibration of the air conditioner 1000, improving the anti-deformation ability of the entire connection part, and reducing the possibility of deformation of the side edge of the air outlet frame assembly 11 or the side edge of the front shell 13.

[0076] The first connecting structure 112 and the second connecting structure 132 jointly enclose at least one closed figure. When the shell assembly 100 is subjected to external force, for example, collision, extrusion or vibration, due to the high stability of the closed figure, the connection mode of the closed figure can form a stable structure that supports and restricts each other between the air outlet frame assembly 11 and the front shell 13. For example, when a certain part is subjected to external force, the adjacent part can provide support and constraint to the part in time through the connection relationship of the closed figure. In this way, the external force on the shell assembly 100 can be evenly dispersed to the entire connection area, avoiding the concentration of external force on a certain point or line. The entire closed figure can jointly resist the external force, reducing the local deformation of the air outlet frame or the front shell 13, effectively resisting the external force or the vibration of the air conditioner 1000, improving the anti-deformation ability of the entire connection part, and reducing the possibility of deformation of the side edge of the air outlet frame assembly 11 or the side edge of the front shell 13.

[0077] According to the shell assembly 100 provided by the embodiment of the present application, the first connecting structure 112 is arranged on the air outlet frame assembly 11 of the shell assembly 100, the second connecting structure 132 is arranged on the front shell 13, and the first connecting structure 112 and the second connecting structure 132 jointly enclose at least one closed figure. Due to the high stability of the closed figure, the connection structure of the closed figure can form a stable structure that supports and restricts each other between the air outlet frame assembly 11 and the front shell 13. The side edge of the air outlet frame assembly 11 and the side edge of the front shell 13 have strong connection stability, the connection strength and rigidity between the side edge of the air outlet frame assembly 11 and the side edge of the front shell 13 are improved, and the anti-deformation ability of the entire connection part is improved, thereby effectively reducing the possibility of deformation of the side edge of the air outlet frame assembly 11 or the side edge of the front shell 13.

[0078] Referring to Figure 6 , Figure 7 and Figure 9 According to some embodiments of the present application, at least part of the closed figure is a polygon. For example, part of the closed figure can be a polygon; for another example, all of the closed figure can be a polygon.

[0079] By making the at least partially closed figure a polygon, the external force received by the front shell component 10 can be better dispersed. When the external force acts on the front shell component 10, the stress can be transmitted and dispersed along the edges and corners of the polygon. Compared with a single linear connection, the multi-point connection of the polygon can avoid stress concentration in a certain place, and reduce the risk of local stress being too large to cause the front shell 13 or the air outlet frame assembly 11 to deform.

[0080] In addition, compared with a circle, a polygon has more edges and corners, which can provide support and connection points 161 in multiple directions. For example, the closed figure is a triangle, and the triangle itself has very high stability, with its three edges supporting each other and being less likely to deform. When at least one triangle constitutes the closed figure, this stability can be extended to the entire first connection structure 112 and the second connection structure 132, so that the connection between the air outlet frame assembly 11 and the front shell 13 in the front shell component 10 is more stable and can effectively reduce deformation.

[0081] Referring to Figure 6 , Figure 7 and Figure 9 , according to some embodiments of the present application, the at least partially closed figure is a quadrilateral. The structure of the quadrilateral closed figure is relatively stable, and the closed figure structure of the quadrilateral can effectively disperse stress. When subjected to an external force, the stress can be evenly distributed along the four edges of the quadrilateral, reducing the situation of local stress concentration. For example, when one of the edges is subjected to an external force, the other three edges of the quadrilateral can also provide strong support, thereby improving the overall deformation resistance of the front shell component 10 and reducing deformation of the front shell component 10.

[0082] Referring to Figure 7 , Figure 9 , Figure 11 and Figure 12 , according to some embodiments of the present application, the first connection structure 112 and the second connection structure 132 are connected by fasteners. By using fasteners to fix the first connection structure 112 and the second connection structure 132 together, the connection between the first connection structure 112 and the second connection structure 132 can be simple and have strong stability, and the first connection structure 112 and the second connection structure 132 can be easily disassembled or assembled.

[0083] Referring to Figure 4 , Figure 5 , Figure 8 and Figure 24According to some embodiments of the present application, the front shell 13 comprises a mounting frame 134, at least part of the air outlet frame assembly 11 is mounted in the mounting frame 134, the mounting frame 134 comprises two first appearance side plates 131 oppositely arranged along the left-right direction, the first appearance side plate 131 extends along the up-down direction, at least part of the air outlet frame assembly 11 is located between the two first appearance side plates 131, and the first appearance side plate 131 is provided with a second connecting structure 132. Among them, at least part of the air outlet frame assembly 11 is mounted in the mounting frame 134, which can include the following cases: for example, part of the air outlet frame assembly 11 can be mounted in the mounting frame 134; for another example, all of the air outlet frame assembly 11 can be mounted in the mounting frame 134.

[0084] The two first appearance side plates 131 can enhance the structural strength of the mounting frame 134 to some extent. At least part of the air outlet frame assembly 11 is located in the mounting frame 134 between the two first appearance side plates 131, which fully utilizes the space inside the front shell 13. This embedded mounting method makes the structure of the front shell 13 and the air outlet frame assembly 11 compact, and also allows the mounting frame 134 to provide support to at least part of the air outlet frame assembly 11. During the operation of the air conditioner 1000, for example, when the air conditioner 1000 vibrates or is externally impacted, the air outlet frame assembly 11 can be relatively stably fixed on the front shell 13, reducing the possibility of movement or shaking of the air outlet frame assembly 11.

[0085] The air outlet frame assembly 11 is provided with a first connecting structure 112, the first appearance side plate 131 is provided with a second connecting structure 132, and the first connecting structure 112 on the air outlet frame assembly 11 is connected with the second connecting structure 132 on the first appearance side plate 131, so as to realize the connection between the air outlet frame assembly 11 and the front shell 13. The air outlet frame assembly 11 forms an air outlet 111, at least part of the air outlet 111 is opposite to the mounting frame 134, and the air outlet frame assembly 11 is connected between the two first appearance side plates 131. This can reduce the shielding area of the first connecting structure 112 and the second connecting structure 132 to the air outlet 111, reduce the resistance when the airflow flows, and make the airflow flow more smoothly.

[0086] Referring to Figures 8-11 According to some embodiments of the present application, the first connecting structure 112 comprises a connecting column 113, the connecting column 113 is arranged at the left and right ends of the air outlet frame assembly 11, the second connecting structure 132 comprises a connecting bracket 1321, the connecting bracket 1321 is arranged on the first appearance side plate 131, and the connecting bracket 1321 and the connecting column 113 are connected by a first fastener 14 and jointly enclose a first closed figure (for example, refer to Figure 9The connecting column 113 and the connecting bracket 1321 are connected by the first fastener 14, so that the connection between the connecting column 113 and the connecting bracket 1321 is simple and stable.

[0087] The connecting column 113 is arranged at the left and right ends of the air outlet frame assembly 11 and cooperates with the connecting bracket 1321 arranged on the first appearance side plate 131 at the left and right sides of the mounting frame 134. The connecting column 113 can guide the assembly of the air outlet frame assembly 11 and the front shell 13, so that the assembly position of the air outlet frame assembly 11 and the front shell 13 in the left-right direction is accurate.

The insertion connection of the first bolt 1324 and the first slot can make the connection between the front shell 13 and the rear shell component 20 simple and have strong stability. In addition, the connection facilitates the disassembly or assembly between the front shell 13 and the rear shell component 20, and facilitates the maintenance or replacement of the front shell 13 or the rear shell component 20.

The second connecting part 1325 is connected with the first connecting part 115 through the second fastener 162, so that the connection between the front shell 13 and the air outlet frame assembly 11 is simple and stable, and the disassembly or assembly between the front shell 13 and the air outlet frame assembly 11 is facilitated.

[0095] The left and right ends of the first reinforcing cross beam 114 are connected with the first connecting part 115 located on the left and right sides respectively, and the second connecting part 1325 is connected with the first connecting part 115. The left and right ends of the second reinforcing cross beam 133 are connected with the second connecting part 1325 through the connecting side plates 1311 located on the left and right sides respectively.

The reinforcing support 1326 can enhance the structural strength of the first appearance side plate 131 to some extent. The reinforcing support 1326 can make the connection between the second reinforcing cross beam 133 and the first appearance side plate 131 more convenient. The second reinforcing cross beam 133 is connected with the first appearance side plate 131 through the reinforcing support 1326, so that the stress of the first appearance side plate 131 can be more evenly transmitted to the second reinforcing cross beam 133. This is conducive to improving the connection reliability between the second reinforcing cross beam 133 and the first appearance side plate 131, avoiding stress concentration at the connecting part between the end of the second reinforcing cross beam 133 and the first appearance side plate 131, and reducing the problem of connection failure between the second reinforcing cross beam 133 and the first appearance side plate 131 caused by stress concentration.

[0098] With reference to Figure 6 According to some embodiments of the present application, the first reinforcing cross beam 114 is located at the upper end of the front shell 13, and the second reinforcing cross beam 133 is located at the upper part of the air outlet frame assembly 11, which can effectively bear external force from above, for example, top extrusion or collision that may be subjected to in the installation and carrying process.

[0099] Further, the air outlet frame assembly 11 is formed with an air outlet 111, which can include a first air outlet 111 and a second air outlet 111, the first air outlet 111 is located above the second air outlet 111, and the heat exchange air supply assembly 600 includes an air outlet channel 1232, the second air outlet 111 is opposite to the air outlet channel 1232, and the air volume of the second air outlet 111 is larger than that of the first air outlet 111, for example, the first reinforcing cross beam 114 and the second reinforcing cross beam 133 can be located in the region corresponding to the first air outlet 111, so as to reduce the shielding area of the first reinforcing cross beam 114 and the second reinforcing cross beam 133 to the second air outlet 111, thereby reducing the flow resistance generated by the first reinforcing cross beam 114 and the second reinforcing cross beam 133 to the airflow flowing to the second air outlet 111, and ensuring that the second air outlet 111 can maintain a larger air volume, which can better balance the structural stability of the front shell component 10 as a whole and the air volume of the second air outlet 111.

[0100] With reference to Figure 4 , Figure 6 , Figure 7 and Figure 8According to some embodiments of the utility model, the first connecting structure 112 includes a connecting column 113, the connecting column 113 is arranged at the left and right ends of the air outlet frame assembly 11, the second connecting structure 132 includes a connecting support 1321, the connecting support 1321 is arranged on the first appearance side plate 131, the connecting support 1321 is connected with the connecting column 113 through the first fastener 14 and the connecting support 1321 and the connecting column 113 jointly enclose the first closed figure, and the first closed figure is located below the second closed figure. The second closed figure and the first closed figure are arranged in a spaced manner along the up-down direction, and the multiple closed figure structures distributed in a spaced manner upwards and downwards can provide multiple support and constraint structures for the front shell part 10. When the front shell part 10 is subjected to external force, stress can be transmitted and dispersed between the first closed figure or the second closed figure or the first closed figure and the second closed figure, so as to avoid stress concentration in a certain local area and reduce the possibility of deformation of the air outlet frame assembly 11 or the front shell 13 caused by stress concentration.

[0101] Further, the air outlet frame assembly 11 is formed with an air outlet 111, the air outlet 111 can include a first air outlet 111 and a second air outlet 111, the first air outlet 111 is located above the second air outlet 111, the heat exchange air supply assembly 600 includes an air outlet channel 1232, the second air outlet 111 is opposite to the air outlet channel 1232, compared with the first air outlet 111, the air volume of the second air outlet 111 is larger, the first closed figure is located on the left and right sides of the second closed figure, by locating the first closed figure below the second closed figure, for example, the second closed figure can be opposite to the first air outlet 111, the shielding area of the reinforcing cross beams in the second closed figure to the air outlet 111 can be reduced, and then the flow resistance generated by the first reinforcing cross beam 114 and the second reinforcing cross beam 133 in the second closed figure to the airflow flowing to the second air outlet 111 can be reduced, so as to ensure that the second air outlet 111 can maintain a larger air volume, so that the structural stability of the front shell part 10 as a whole and the air volume of the second air outlet 111 can be better balanced.

[0102] Referring to Figure 25According to some embodiments of the utility model, a plurality of connecting supports 1321 are arranged along the up-down direction on the same first appearance side plate 131, the connecting column 113 at the same end of the air outlet frame assembly 11 along the left-right direction is a plurality of connecting supports arranged along the up-down direction, the spacing between the lowermost connecting support 1321 and the bottom of the first appearance side plate 131 along the up-down direction is h1, the spacing between the adjacent two connecting supports 1321 is h2, and the spacing between the second reinforcing cross beam 133 and the uppermost connecting support 1321 is h3, and the ratio range between any two of h1, h2 and h3 is 0.6-1.5. For example, the ratio range between any two of h1, h2 and h3 can be 0.6, 0.8, 1.0, 1.2, 1.5, etc.

[0103] The connecting support 1321 and the connecting column 113 jointly enclose the first closed figure, the first reinforcing cross beam 114, the two connecting side plates 1311 and the second reinforcing cross beam 133 jointly enclose the second closed figure, and the ratio range between any two of h1, h2 and h3 is 0.6-1.5, so that the second closed figure and the two first closed figures can be arranged along the up-down direction at a relatively uniform interval, which can make the multiple connecting parts between the front shell 13 and the air outlet frame assembly 11 more evenly disperse the stress, thereby effectively enhancing the overall structural stability and anti-deformation ability of the front shell part 10 and reducing the deformation of the front shell part 10 due to uneven local stress.

[0104] It should be explained that the lowermost connecting support 1321 is the connecting support 1321 closest to the first appearance side plate 131 along the up-down direction, and the uppermost connecting support 1321 is the connecting support 1321 closest to the second reinforcing cross beam 133 along the up-down direction.

[0105] Referring to Figure 24 and Figure 25 According to some embodiments of the utility model, the size of the first appearance side plate 131 along the up-down direction is L1, the size of the first appearance side plate 131 along the front-rear direction is L2, and the size of the first appearance side plate 131 along the left-right direction is L3, and the ratio of L1 to L2 and the ratio of L1 to L3 are both greater than 10. Since the size L1 of the first appearance side plate 131 along the up-down direction and the size L2 of the first appearance side plate 131 along the front-rear direction and the size L3 of the first appearance side plate 131 along the left-right direction have a ratio greater than 10, the first appearance side plate 131 has an elongated narrow edge structure, which can reduce the space in the left-right direction and the front-rear direction, facilitating the installation and layout of other internal components.

The second appearance side plate 1216 is located at the left and right ends of front air outlet frame 121 and is butt-jointed with the edge of mounting frame 134, and the second appearance side plate 1216 located at the same side in the left-right direction is located at the front side of the corresponding first appearance side plate 131, and the bottom frame plate 1217 is butt-jointed with the bottom wall of mounting frame 134, so that the left and right ends and the bottom of front air outlet frame 121 are respectively butt-jointed with the left and right ends and the bottom of mounting frame 134, so that the left and right sides and the bottom of front shell component 10 are relatively complete closed structure, and the overall appearance of front shell component 10 can be improved.

[0122] Referring to Figure 1 , Figure 5 and Figure 18 , according to some embodiments of the utility model, bottom frame plate 1217 includes first frame plate 1218 and two second frame plates 1219, two second frame plates 1219 are connected on the left and right sides of first frame plate 1218, second frame plate 1219 connects first frame plate 1218 and second appearance side plate 1216, and second frame plate 1219 extends in an arc shape with the butt-joint gap of front shell 13. Compared with the straight extension of the edge of second frame plate 1219, the arc extension of the edge of second frame plate 1219 can make the edge of second frame plate 1219 as close as possible to the edge of front shell 13, so that the butt-joint gap between second frame plate 1219 and front shell 13 is as small as possible, which can reduce the accumulation of dust in the butt-joint gap between second frame plate 1219 and front shell 13, and also helps to improve the overall appearance of front shell component 10.

[0123] Referring to Figure 1 , Figure 5 and Figure 18 , according to some embodiments of the utility model, the width of the butt-joint gap is less than 0.3mm. For example, the width of the butt-joint gap can be 0mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc. By controlling the width of the butt-joint gap within 0.3mm, the butt-joint gap between second frame plate 1219 and front shell 13 can be smaller, which can improve the overall appearance of front shell component 10, and also can reduce the accumulation of dust and other impurities in the butt-joint gap between second frame plate 1219 and front shell 13.

[0124] Referring to Figures 13-15 According to some embodiments of the present application, the front air outlet frame 121 and the rear air outlet frame 123 are connected by the fifth fastener 124, the front air outlet frame 121 has a first matching surface 1220, the rear air outlet frame 123 has a second matching surface 1231, the first matching surface 1220 and the second matching surface 1231 are opposite and are spaced apart, the fifth fastener 124 is connected between the first matching surface 1220 and the second matching surface 1231, and the distance w1 between the first matching surface 1220 and the second matching surface 1231 ranges from 1.5 mm to 2.5 mm. The fifth fastener 124 can make the connection between the front air outlet frame 121 and the rear air outlet frame 123 simple and have strong stability, and can also realize detachable connection between the front air outlet frame 121 and the rear air outlet frame 123.

[0125] For example, the distance w1 between the first matching surface 1220 and the second matching surface 1231 can be 1.5 mm, 1.8 mm, 2 mm, 2.3 mm, 2.5 mm, etc., and by the distance w1 between the first matching surface 1220 and the second matching surface 1231 ranging from 1.5 mm to 2.5 mm, the problem of abnormal noise or extrusion wear caused by thermal expansion and cold contraction of the front air outlet frame 121 and the rear air outlet frame 123 can be reduced, and the abnormal noise caused by the collision of the front air outlet frame 121 and the rear air outlet frame 123 due to vibration of the air conditioner 1000 during operation can also be reduced.

[0126] For example, if the distance w1 between the first matching surface 1220 and the second matching surface 1231 is too small, the air conditioner 1000 will vibrate during operation, and the front air outlet frame 121 and the rear air outlet frame 123 may collide and produce abnormal noise. When the air conditioner 1000 is operated in heating mode, the airflow temperature flowing through the front air outlet frame 121 and the rear air outlet frame 123 may be too high, which can easily cause thermal expansion of the front air outlet frame 121 or the rear air outlet frame 123, and the expansion degree of each of the front air outlet frame 121 or the rear air outlet frame 123 will be different, which can cause the distance between the first matching surface 1220 and the second matching surface 1231 to decrease and cause the front air outlet frame 121 and the rear air outlet frame 123 to be extruded, thereby producing wear or noise. By the distance w1 between the first matching surface 1220 and the second matching surface 1231 ranging from 1.5 mm to 2.5 mm, the change in the distance between the first matching surface 1220 and the second matching surface 1231 caused by the difference in expansion degree can be effectively reduced, and thus the noise or wear caused by the change in the distance between the first matching surface 1220 and the second matching surface 1231 can be reduced.

[0127] For another example, if the distance w1 between the first fitting surface 1220 and the second fitting surface 1231 is too large, the air flow temperature flowing through the front air outlet frame 121 and the rear air outlet frame 123 may be too low when the air conditioner 1000 works in the cooling mode, which is easy to cause the front air outlet frame 121 or the rear air outlet frame to have a cold shrinkage phenomenon, and the cold shrinkage degrees of the front air outlet frame 121 and the rear air outlet frame are different, which may cause the distance between the first fitting surface 1220 and the second fitting surface 1231 to be larger, thereby reducing the connection stability between the front air outlet frame 121 and the rear air outlet frame 123, and causing the air conditioner 1000 to vibrate when working, and further causing the connection part of the front air outlet frame 121 and the rear air outlet frame 123 to have an abnormal sound.

[0128] By setting the distance w1 between the first fitting surface 1220 and the second fitting surface 1231 to be 1.5mm-2.5mm, the influence caused by the change of the distance between the first fitting surface 1220 and the second fitting surface 1231 due to the difference in the expansion degree or the cold shrinkage degree can be effectively reduced, and further, the noise or extrusion wear caused by the change of the distance can be reduced.
