Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a chassis and a ceiling-mounted air conditioner. Background Technology

[0002] Some air conditioners in related technologies are suspended from the ceiling to form ceiling-mounted air conditioners. Ceiling-mounted air conditioners have more outer casing components, resulting in low assembly efficiency. In addition, to improve the connection strength and rigidity between parts, the material thickness of the outer casing components needs to be increased, thereby increasing the cost and weight of the ceiling-mounted air conditioner. Summary of the Invention

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a chassis for a ceiling-mounted air conditioner, which improves the assembly efficiency of the entire unit and helps reduce the overall cost and weight.

[0006] According to the chassis of this application embodiment, since it is a one-piece molded part, the base plate and the panel are different parts of a single piece of sheet metal. Therefore, the process of separately processing the base plate and the panel in related technologies can be eliminated, as can the process of assembling the base plate and the panel together in related technologies, thereby significantly improving production efficiency. Moreover, since the base plate and the panel are one-piece molded parts, the connection strength and rigidity between the two are large. Therefore, it is not necessary to thicken the materials of the base plate and the panel separately to improve the connection strength and rigidity. This is equivalent to appropriately reducing the material thickness of the base plate and the panel, thereby reducing the overall cost and weight of the machine and facilitating hoisting.

[0015] In some embodiments, the base plate portion is rectangular and includes two long edges and two short edges, each of the short edges being the second edge, such that the lug portions are respectively provided at both ends of the length of the base plate portion, and one of the long edges is the first edge.

[0016] A ceiling-mounted air conditioner according to a second aspect of this application includes: a chassis, a side panel, a ventilation component, a heat exchange component, and a top cover assembly. The chassis is the same as the chassis according to a first aspect of this application. The side panel is mounted on the chassis and located on the first side to define a receiving cavity between itself and the panel portion.

[0067] The embodiments of this application 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 intended to explain this application, and should not be construed as limiting this application.

[0068] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0069] Ceiling-mounted air conditioners refer to indoor units or integrated air conditioning units that are suspended from the ceiling. For example, such as... Figures 1-3 As shown, the ceiling-mounted air conditioner 100 may include a ventilation component 3 and a heat exchange component 4. The ceiling-mounted air conditioner 100 is suspended on the ceiling 200 and located above the ceiling 300.

[0070] In the embodiments of this application, such as Figure 3 and Figure 4As shown, the outer casing of the ceiling-mounted air conditioner 100 may include the chassis 1 of this application embodiment. The chassis 1 is an integrally formed part and includes a bottom plate portion 11 and a panel portion 12. The thickness of the bottom plate portion 11 is divided into a first side and a second side on both sides. The surface of the bottom plate portion 11 facing the first side is provided with a first mounting structure 111 for mounting the ventilation component 3. The panel portion 12 is connected to the edge of the bottom plate portion 11 and extends along the direction from the second side to the first side. The panel portion 12 has an opening 121, which is adapted to correspond to the outlet 3133 of the ventilation component 3.

[0071] For example, when assembling the ceiling-mounted air conditioner 100, the base plate 11 is placed on the mounting surface, and the panel 12 extends upward from the edge of the base plate 11 (e.g.) Figure 3 (As shown in the orientation), then install the ventilation component 3 above the base plate 11, so that the outlet 3133 of the ventilation component 3 faces the opening 121 on the panel 12. After assembling the ceiling-mounted air conditioner 100, flip the entire ceiling-mounted air conditioner 100 upside down so that the base plate 11 is located at the top of the entire unit (e.g., in the orientation state shown). Figure 2 (As shown in the orientation state), the panel portion 12 extends downward from the edge of the base plate portion 11.

[0072] In related technologies, the base plate for mounting ventilation components and the panel for setting openings are two separate parts that need to be manufactured individually. Furthermore, connecting structures need to be installed on each part to facilitate subsequent assembly. This not only involves numerous steps in manufacturing each part individually, but also makes the assembly process quite complex. Moreover, to ensure the connection strength and rigidity after assembly, the materials for both the base plate and the panel need to be thicker, resulting in higher overall costs and a heavier overall weight, which is detrimental to hoisting.

[0073] According to the chassis 1 of this application embodiment, since it is a one-piece molded part, the base plate 11 and the panel 12 are different parts of a single piece of sheet metal. Therefore, the process of separately processing the base plate and the panel in related technologies can be eliminated, as can the process of assembling the base plate and the panel together in related technologies, thereby significantly improving production efficiency. Moreover, since the base plate 11 and the panel 12 are one-piece molded parts, the connection strength and rigidity between the two are large. Therefore, it is not necessary to thicken the materials of the base plate 11 and the panel 12 separately to improve the connection strength and rigidity. This is equivalent to appropriately reducing the material thickness of the base plate 11 and the panel 12, thereby reducing the overall cost and weight of the machine and facilitating hoisting.

[0074] like Figures 3-6As shown, the ventilation component 3 may include a fan assembly and a motor assembly. The fan assembly includes a fan wheel 311 and a volute 313, and the motor assembly includes a motor 321 and a bracket 322. Both the bracket 322 and the volute 313 are mounted on the chassis 1. The fan wheel 311 is installed inside the volute 313. The motor 321 is connected to the fan wheel 311 and is supported by the bracket 322. Figure 4 (The bracket 322 is hidden inside).

[0075] In some embodiments of this application, such as Figures 4-6 As shown, the first mounting structure 111 includes a first mounting portion 111a for mounting the volute 313 in the ventilation component 3, and a second mounting portion 111b for mounting the bracket 322 in the ventilation component 3. Therefore, the ventilation component 3 can be integrally mounted on the base plate 11, thereby simplifying assembly and improving assembly efficiency. Of course, this application is not limited to this; in other embodiments of this application, only one of the first mounting portion 111a and the second mounting portion 111b may be provided.

[0076] Specifically, the specific forms of the first mounting part 111a and the second mounting part 111b are not limited, and can be designed according to the corresponding connection structures on the volute 313 and the bracket 322.

[0077] For example, such as Figures 3-6 As shown, the volute 313 may include a lower volute 3131 and an upper volute 3132 mounted on the lower volute 3131. The upper volute 3132 is located on the side of the lower volute 3131 away from the base plate portion 11. The lower volute 3131 includes a first connecting portion 31311 for connecting the base plate portion 11. The first mounting portion 111a and the first connecting portion 31311 may be positioned and / or fastened (e.g., positioned by a first positioning post and a first positioning hole, and fastened by a first screw 81).

[0078] Furthermore, a first recessed structure 112 and a first protruding structure 113 may be formed on the base plate portion 11. The first mounting structure 111 may be disposed on the first protruding structure 113 to cooperate and connect with the first connecting portion 31311. The first recessed structure 112 is used to avoid the portion of the lower volute 3131 that protrudes in the direction relative to the first connecting portion 31311 toward the base plate portion 11, thereby improving the tightness of the fit and improving the strength and rigidity of the base plate portion 11.

[0079] For example, such as Figures 3-6As shown, the bracket 322 may include a third connecting part 3221 for connecting the base plate part 11. The second mounting part 111b and the third connecting part 3221 may be a positioning fit and / or a fastening connection (e.g., a positioning fit through the first insert and the first insertion hole, a positioning fit through the second positioning post and the second positioning hole, and a fastening connection through the second screw 82).

[0080] Furthermore, a second protruding structure 114 can be formed on the base plate 11, and a second mounting part 111b can be disposed on the second protruding structure 114 to cooperate and connect with the third connecting part 3221, thereby improving the strength and rigidity of the corresponding position of the base plate 11, and thus improving the reliability of the bracket 322 in supporting the motor 321.

[0081] In some embodiments of this application, such as Figures 4-6 As shown, the panel portion 12 has a second mounting structure 122 for mounting the ventilation component 3. Therefore, the ventilation component 3 is connected not only to the base plate portion 11, but also to the panel portion 12, thereby improving the overall reliability of the connection between the ventilation component 3 and the chassis 1.

[0082] For example, such as Figures 4-6 As shown, the second mounting structure 122 includes a third mounting portion 1221 for mounting the volute 313 in the ventilation component 3, and a fourth mounting portion 1222 for mounting the bracket 322 in the ventilation component 3. This improves the connection reliability between the volute 313 and the bracket 322 and the chassis 1, respectively. However, this application is not limited to this; in other embodiments, only one of the third mounting portion 1221 and the fourth mounting portion 1222 may be provided.

[0083] Specifically, the specific forms of the third mounting part 1221 and the fourth mounting part 1222 are not limited, and can be designed according to the corresponding connection structure on the volute 313 and the bracket 322.

[0084] For example, such as Figures 3-6 As shown, the volute 313 may include a lower volute 3131 and an upper volute 3132 mounted on the lower volute 3131. The upper volute 3132 is located on the side of the lower volute 3131 away from the bottom plate portion 11. The lower volute 3131 includes a second connecting portion 31312 for connecting the panel portion 12. The third mounting portion 1221 and the second connecting portion 31312 can be positioned and / or fastened together. For example, combined with Figures 7-12The third mounting part 1221 includes a first locking hole b1, a third positioning hole b2 and a first through hole b3. The second connecting part 31312 includes a first locking hook a1, a third positioning post a2 and a first screw hole a3. The first locking hook a1 and the first locking hole b1 are positioned and engaged, the third positioning post a2 and the third positioning hole b2 are positioned and engaged, and the connection is fastened by a third screw that passes through the first through hole b3 and is threaded to the first screw hole a3.

[0085] For example, such as Figures 3-6 As shown, the bracket 322 may include a fourth connecting portion 3222 for connecting the panel portion 12. The fourth mounting portion 1222 and the fourth connecting portion 3222 may be a positioning fit and / or a fastening connection (e.g., fastening connection by a fourth screw).

[0086] In some embodiments, combined with Figure 13 and Figure 14 The lower volute 3131 has a frame portion 31313, which defines the outlet 3133 of the ventilation component 3. The frame portion 31313 surrounds the opening 121 and abuts against the inner side of the panel portion 12, thereby allowing for a simple and reliable correspondence between the opening 121 and the outlet 3133 of the ventilation component 3. Figure 7 The first hook a1, the third positioning post a2, and the first screw hole a3 are all located on the frame part 31313.

[0087] In some embodiments of this application, such as Figure 15 and Figure 16 As shown, the panel portion 12 has a third mounting structure 123 for mounting the air vent component 6. The ceiling-mounted air conditioner 100 also includes the air vent component 6, which is located on the outer side of the panel portion 12. The air vent component 6 may include a fifth connecting portion 61 for connecting to the panel portion 12. The fifth connecting portion 61 and the third mounting structure 123 can be positioned and / or fastened (for example, positioned by the second hook a4 and the second hook hole b4, and fastened by the fifth screw passing through the second through hole a5 and the second screw hole b5). Thus, the panel portion 12 can have the function of connecting the air vent component 6.

[0088] When the panel 12 pieces are simultaneously provided with a third mounting structure 123 and a second mounting structure 122, the third mounting structure 123 and the second mounting structure 122 are staggered to avoid installation interference. Meanwhile, combined with… Figure 7 The area corresponding to the lower volute 3131 and the third mounting structure 123 has a clearance structure 31314, thereby ensuring that the fifth connecting part 61 and the third mounting structure 123 can be smoothly assembled.

[0089] For example, the fifth connecting part 61 includes a second hook a4 provided on the air vent component 6, the third mounting structure 123 includes a second locking hole b4 formed on the panel part 12, and the outer periphery of the frame part 31313 of the lower volute 3131 extends partially to a support part 31315 supported on the inner side of the panel part 12. The support part 31315 is provided corresponding to the second locking hole b4 and has a groove recessed in the direction away from the panel part 12 as a clearance structure 31314. The second hook a4 is inserted into the second locking hole b4 on the inner side of the panel part 12 and housed in the clearance structure 31314, thereby improving the structural compactness.

[0090] Furthermore, the fifth connecting part 61 may also include a second through hole a5 provided on the air outlet component 6, and the third mounting structure 123 includes a second screw hole b5 provided on the panel part 12. When the second hook a4 and the second hook hole b4 are engaged, the fifth screw can be passed through the second through hole a5 and threaded to the second screw hole b5, thereby improving the installation reliability of the air outlet component 6.

[0091] In some embodiments of this application, such as Figure 16 and Figure 17 The end of the panel portion 12 away from the base plate portion 11 has a fourth mounting structure 124 for mounting the top cover assembly 5 of the ceiling-mounted air conditioner 100. The top cover assembly 5 is located on the side of the panel portion 12 away from the base plate portion 11, and the top cover assembly 5 may include a sixth connecting portion for connecting the panel portion 12. The sixth connecting portion and the fourth mounting structure 124 may be in a positioning fit and / or a fastening connection (e.g., fastened by a sixth screw, etc.). Thus, the panel portion 12 can have the function of connecting the top cover assembly 5.

[0092] In some embodiments of this application, such as Figure 18 and Figure 19 The base plate portion 11 includes a first edge 1101 and a second edge 1102 disposed on opposite sides, meaning that the first edge 1101 and the second edge 1102 are not edges on the same side of the base plate portion 11. The panel portion 12 is connected to the first edge 1101, and the chassis 1 also includes a lifting lug portion 13, which is connected to the second edge 1102, and at least a portion of the lifting lug portion 13 is located outside the outline of the base plate portion 11. The chassis 1 is adapted to be suspended to the ceiling 200 via the lifting lug portion 13.

[0093] Therefore, since the chassis 1 is a one-piece molded component, the base plate 11, the panel 12, and the lifting lug 13 are all different parts of a single piece of sheet metal. This eliminates the need for separate processing of the lifting lugs and the process of installing them onto the base plate, thus significantly improving production efficiency. Furthermore, because the base plate 11 and the lifting lug 13 are one-piece molded components, their connection strength and rigidity are high. Therefore, it is not necessary to thicken the materials of the base plate 11 and the lifting lug 13 separately to increase connection strength and rigidity. This effectively reduces the material thickness of the base plate 11 and the lifting lug 13, thereby lowering the overall machine cost and weight, which is beneficial for lifting operations.

[0094] like Figure 18 and Figure 19 As shown, the lifting lug 13 extends along the length direction of the second edge 1102 and has a plurality of lifting holes 131 spaced apart along the length direction of the second edge 1102. The lifting holes 131 are adapted to cooperate with the suspension rod 400 connected to the ceiling 200 for hoisting. This allows for full utilization of space and improves the reliability of the hanging connection. Furthermore, the cooperation between the lifting holes 131 and the suspension rod 400 facilitates the installation of the suspension rod 400 and improves installation efficiency. The type of suspension rod 400 is not limited; for example, it can be an expansion bolt.

[0095] In some embodiments of this application, such as Figure 18 and Figure 19 As shown, at least one of the following locations is provided with reinforcing ribs 14: the lug portion 13, a portion of the base plate portion 11 near the second edge 1102, and the connection between the lug portion 13 and the base plate portion 11. This improves the installation reliability of the ceiling-mounted air conditioner 100.

[0096] For example, the reinforcing rib 14 may include a first reinforcing rib 141 provided on the lug portion 13. The first reinforcing rib 141 may be adapted to the outer periphery of the lug 131, thereby improving the structural strength and rigidity of the lug portion 13.

[0097] For example, the reinforcing rib 14 may include a second reinforcing rib 142 and a third reinforcing rib 143 disposed on the base plate portion 11, both the second reinforcing rib 142 and the third reinforcing rib 143 being disposed on the portion of the base plate portion 11 near the second edge 1102. For example, the base plate portion 11 may include a base plate bottom wall 11a and a base plate side wall 11b, the base plate side wall 11b being disposed perpendicular to the base plate bottom wall 11a, the lifting lug portion 13 being connected to the base plate bottom wall 11a via the base plate side wall 11b, and the base plate side wall 11b being provided with the second reinforcing rib 142. For example, the connection between the base plate bottom wall 11a and the base plate side wall 11b is provided with the third reinforcing rib 143.

[0098] For example, the reinforcing rib 14 may include a fourth reinforcing rib 144 disposed at the connection between the lifting lug 13 and the base plate 11. For example, the base plate 11 may include a bottom wall 11a and a side wall 11b, the side wall 11b being disposed perpendicular to the bottom wall 11a, the lifting lug 13 being connected to the bottom wall 11a via the side wall 11b, and the fourth reinforcing rib 144 being disposed at the connection between the lifting lug 13 and the side wall 11b.

[0099] For example, the second reinforcing rib 142 can be spaced apart along the length direction of the second edge 1102, the third reinforcing rib 143 can be spaced apart along the length direction of the second edge 1102, and the fourth reinforcing rib 144 can be spaced apart along the length direction of the second edge 1102. One of the two adjacent second reinforcing ribs 142 extends to the lug portion 13 and intersects with the fourth reinforcing rib 144, and the other of the two adjacent second reinforcing ribs 142 extends to the bottom wall 11a of the base plate and intersects with the third reinforcing rib 143.
