[0040] The air conditioner 1000 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0041] According to an embodiment of the present invention, an air conditioner 1000, as shown in Figures 1 and 2, includes a chassis 100, functional components 200, and fasteners 600. The functional components 200 are disposed on the chassis 100 and include a ventilation and heat exchange component 3, an electrical control box 4, and a fresh air component 5. The ventilation and heat exchange component 3, the electrical control box 4, and the fresh air component 5 are arranged sequentially along the length of the ventilation and heat exchange component 3. The fasteners 600 pass through the electrical control box 4 and the fresh air component 5 and are connected to the chassis 100, thereby fixing the chassis 100, the electrical control box 4, and the fresh air component 5 relatively. The fasteners 600 fixing the chassis 100, the electrical control box 4, and the fresh air component 5 means that, under the action of the fasteners 600, the chassis 100, the electrical control box 4, and the fresh air component 5 are inseparable.

[0042] The chassis 100 provides support, and the functional components 200 are mounted on the chassis 100. The functional components 200 include a ventilation and heat exchange component 3, an electrical control box 4, and a fresh air component 5. The ventilation and heat exchange component 3 provides heat exchange airflow, the electrical control box 4 controls the operation of the ventilation and heat exchange component 3 and the fresh air component 5, and the fresh air component 5 provides fresh air. The ventilation and heat exchange component 3, the electrical control box 4, and the fresh air component 5 are arranged sequentially along the length of the ventilation and heat exchange component 3, with a neat layout, high space utilization, and good structural compactness.

[0043] In this embodiment of the invention, the air conditioner 1000 uses a fastener 600 to pass through the electrical control box 4 and the fresh air component 5, thereby connecting the electrical control box 4 and the fresh air component 5 together to the chassis 100, and connecting the electrical control box 4 and the chassis 100. Using only one fastener 600 completes the connection and fixation of the electrical control box 4, the fresh air component 5, and the chassis 100, saving on the number of fasteners used and reducing manufacturing costs; furthermore, it simplifies the disassembly and assembly steps of the electrical control box 4, the fresh air component 5, and the chassis 100, improving disassembly and assembly efficiency and facilitating subsequent maintenance of the air conditioner 1000.

[0044] Compared to related technologies where the control box and fresh air component are connected to the chassis respectively and there is no connection between the control box and the fresh air component, in this embodiment of the invention, the control box 4 and the fresh air component 5 are also connected and fixed. On the basis of realizing the connection between the functional component 200 and the chassis 100, the reliability of the connection between the functional components 200 can be improved, the structural compactness of the functional component 200 can be improved, and the structural stability of the air conditioner 1000 can be improved.

[0045] The air conditioner 1000 of this embodiment uses a fastener 600 to pass through the electrical control box 4 and the fresh air component 5 to fix the electrical control box 4 and the fresh air component 5 together to the chassis 100. The relative fixation of the electrical control box 4, the fresh air component 5 and the chassis 100 can be completed with a single fastener 600, which can reduce manufacturing costs and improve the assembly and disassembly efficiency of the air conditioner 1000. The connection and fixation between the electrical control box 4 and the fresh air component 5 can also improve the connection reliability between the functional components 200 and improve the structural stability of the air conditioner 1000.

[0046] In some embodiments of the present invention, as shown in FIG3, the chassis 100 includes a first wall portion 11, the fresh air component 5 includes a second wall portion 51, the electrical control box 4 includes a third wall portion 41, the second wall portion 51 is located between the first wall portion 11 and the third wall portion 41, and the fastener 600 passes through the third wall portion 41 and the second wall portion 51 and is connected to the connection structure 12 provided on the first wall portion 11.

[0047] Fastener 600 is installed from the side of the third wall 41 away from the first wall 11 toward the first wall 11. Fastener 600 passes through the third wall 41 of the electrical control box 4 and the second wall 51 of the fresh air component 5 in sequence. Fastener 600 is connected to the connection structure 12 on the chassis 100, thereby connecting both the electrical control box 4 and the fresh air component 5 to the chassis 100.

[0048] In some embodiments of the present invention, as shown in FIG3, the connecting structure 12 is a first protrusion 121 extending toward the third wall portion 41, the second wall portion 51 is provided with a first positioning hole 52, the first protrusion 121 passes through the first positioning hole 52, the third wall portion 41 is provided with a through hole 42, the through hole 42 is opposite to the first protrusion 121, and the fastener 600 passes through the through hole 42 and is connected to the first protrusion 121.

[0049] The first wall portion 11 of the chassis 100 is provided with a first protrusion 121 protruding toward the third wall portion 41. The second wall portion 51 located between the first wall portion 11 and the third wall portion 41 is provided with a first positioning hole 52. The first protrusion 121 passes through the first positioning hole 52 to pre-position the first wall portion 11 and the second wall portion 51.

[0050] After the first protrusion 121 and the first positioning hole 52 are engaged to position the first wall portion 11 and the second wall portion 51 relative to each other, the third wall portion 41 is then connected relative to the first wall portion 11. A through hole 42 is provided on the third wall portion 41 of the electrical control box 4, and the through hole 42 is arranged directly opposite to the first protrusion 121.

[0051] Fastener 600 passes through through hole 42 and connects with first protrusion 121, thereby connecting third wall portion 41 with first wall portion 11. Second wall portion 51 is clamped by first wall portion 11 and third wall portion 41 and positioned with first wall portion 11, thereby also connecting with first wall portion 11 and third wall portion 41 to fix electrical control box 4 and fresh air component 5 relative to chassis 100.

[0052] In some embodiments of the present invention, as shown in Figures 3 and 4, the first protrusion 121 is a threaded post 121a and defines a threaded hole 1211, the fastener 600 is a screw 6a, the head of the screw 6a abuts against the side of the third wall portion 41 away from the first wall portion 11, and the shank of the screw 6a is threadedly connected to the threaded hole 1211.

[0053] The screw 6a passes through the third wall 41 and the second wall 51 and is threadedly connected to the threaded post 121a on the first wall 11. The connection method of the screw 6a is simple and the connection reliability is strong, which is conducive to improving assembly efficiency and structural stability.

[0054] Screw 6a is installed from the side of the third wall portion 41 away from the first wall portion 11 toward the first wall portion 11. The shank of screw 6a passes through the through hole 42 on the third wall portion 41 of the electrical control box 4. Then, screw 6a extends into the threaded hole 1211 on the chassis 100. The thread of the shank of screw 6a is threaded into the threaded hole 1211. The head of screw 6a abuts against the side of the third wall portion 41 away from the first wall portion 11. The second wall portion 51 is fitted onto the outer periphery of the threaded post 121a through the first positioning hole 52. After the first wall portion 11 and the third wall portion 41 are fixedly connected by screw 6a, the second wall portion 51 in the middle is clamped and fixed, thereby connecting both the electrical control box 4 and the fresh air component 5 to the chassis 100.

[0055] Not limited to this, the first wall portion 11, the second wall portion 51 and the third wall portion 41 can also be connected by riveting, bonding or other methods.

[0056] In some embodiments of the present invention, as shown in FIG3, the second wall portion 51 includes a sleeve portion 511, the axial direction of which extends along the direction from the first wall portion 11 to the third wall portion 41, and the sleeve portion 511 surrounds the first positioning hole 52. The sleeve portion 511 surrounds the first protrusion 121 circumferentially, such that the first protrusion 121 passes through the first positioning hole 52 formed in the sleeve portion 511, and the sleeve portion 511 is sandwiched between the first wall portion 11 and the second wall portion 51.

[0057] As shown in Figure 4, the fresh air component 5 also includes a vibration damping structure 53. The vibration damping structure 53 includes a first vibration damping part 531 and a second vibration damping part 532 respectively disposed at both axial ends of the sleeve part 511. The first vibration damping part 531 is placed between the sleeve part 511 and the first wall part 11, and the second vibration damping part 532 is placed between the sleeve part 511 and the third wall part 41.

[0058] By providing a first vibration damping part 531 between the sleeve part 511 and the first wall part 11, and a second vibration damping part 532 between the sleeve part 511 and the second wall part 51, the connection stability between the sleeve part 511 and the first wall part 11, and the connection stability between the sleeve part 511 and the second wall part 51 can be improved. Compared with the sleeve part 511 being in direct contact with the first wall part 11 and the second wall part 51, the use of the vibration damping structure 53 can reduce wear, reduce vibration and noise, and extend service life.

[0059] It is worth noting that the fresh air component 5 vibrates during operation. By setting the vibration damping structure 53, the vibration of the fresh air component 5 can be reduced from being transmitted to the chassis 100 and the electrical control box 4, thus reducing vibration and noise, and improving the working stability of the electrical control box 4.

[0060] In some embodiments of the present invention, as shown in FIG4, the vibration damping structure 53 is an integral part, and also includes a connecting part 533 connecting the first vibration damping part 531 and the second vibration damping part 532. The connecting part 533 is annular and passes through the sleeve part 511, that is, passes through the first positioning hole 52. The first protrusion 121 passes through the annular hole 5331 of the connecting part 533.

[0061] The vibration damping structure 53 is a single piece, which can improve the overall integrity and structural stability of the vibration damping structure 53. The connecting part 533 of the vibration damping structure 53 passes through the sleeve part 511. The first vibration damping part 531 and the second vibration damping part 532 are respectively connected to the two ends of the connecting part 533 along the axial direction. The first vibration damping part 531 protrudes radially to be placed between the sleeve part 511 and the first wall part 11; the second vibration damping part 532 protrudes radially to be placed between the sleeve part 511 and the second wall part 51.

[0062] The connecting portion 533 is located between the sleeve portion 511 and the first protrusion 121, which can improve the connection stability of the first wall portion 11 and the second wall portion 51, and reduce the wear between the sleeve portion 511 and the first protrusion 121.

[0063] In some embodiments of the present invention, as shown in FIG4, the fresh air component 5 and the electrical control box 4 are positioned and engaged by the positioning structure 43.

[0064] After the fresh air component 5 and the electrical control box 4 are positioned and engaged by the positioning structure 43, they are then connected together to the chassis 100 by the fasteners 600. This assembly method of positioning first and then fixing the connection can improve the assembly efficiency and connection accuracy of the fresh air component 5 and the electrical control box 4.

[0065] In some embodiments of the present invention, as shown in FIG4, the fresh air component 5 and the electrical control box 4 are positioned and engaged by a positioning structure 43. The positioning structure 43 includes a second protrusion 512 and a second positioning hole 411. The second protrusion 512 is disposed on the second wall portion 51 and extends toward the third wall portion 41. The second positioning hole 411 is opened in the third wall portion 41, and the second protrusion 512 passes through the second positioning hole 411.

[0066] The positioning structure 43 includes a second protrusion 512 disposed on the second wall portion 51 of the fresh air component 5 and a second positioning hole 411 opened on the third wall portion 41 of the electrical control box 4. The second protrusion 512 extends toward the third wall portion 41 and passes through the second positioning hole 411 to position and engage the fresh air component 5 and the electrical control box 4, thereby improving the assembly efficiency and accuracy of the fresh air component 5, the electrical control box 4 and the chassis 100.

[0067] During assembly, the second protrusion 512 is first inserted into the second positioning hole 411 to position the fresh air component 5 and the electrical control box 4 relative to each other. Then, the fastener 600 passes through the third wall portion 41 and the second wall portion 51 and connects to the connecting structure 12 provided on the first wall portion 11, thereby connecting both the electrical control box 4 and the fresh air component 5 to the chassis 100. This method of positioning before fixing improves the assembly efficiency and accuracy of the fresh air component 5, the electrical control box 4, and the chassis 100.

[0068] In some embodiments of the present invention, as shown in Figures 1 and 3, the length direction of the ventilation and heat exchange component 3 is the first direction F1, the third wall portion 41, the second wall portion 51 and the first wall portion 11 are arranged sequentially along the second direction F2 which is perpendicular to the first direction F1, and the fastener 600 passes through along the second direction F2.

[0069] The length direction of the ventilation and heat exchange component 3 is the first direction F1. The ventilation and heat exchange component 3, the electrical control box 4, and the fresh air component 5 are arranged in sequence along the first direction F1. Therefore, the space on the first direction F1 of the electrical control box 4 and the fresh air component 5 is limited.

[0070] By sequentially arranging the third wall portion 41, the second wall portion 51, and the first wall portion 11 along the second direction F2 perpendicular to the first direction F1, the fastener 600 has a larger space to move, which facilitates operation and improves disassembly and assembly efficiency.

[0071] For example, the fastener 600 is a screw 6a, and the operation of driving or removing the screw along the second direction F2 is simple and can improve the efficiency of disassembly and assembly.

[0072] In some embodiments of the present invention, as shown in FIG1, the air conditioner 1000 is a wall-mounted air conditioner, and the length direction of the ventilation and heat exchange component 3 is the left-right direction. As shown in FIG6, the electrical control box 4 includes a box body 4a and a box cover 4b. The box cover 4b is disposed on the front side of the box body 4a. As shown in FIG5 and FIG6, the box body 4a includes a first box part 4a1 and a second box part 4a2. The second box part 4a2 is connected to the lower front end of the first box part 4a1.

[0073] The electrical control box 4 includes a box body 4a and a cover 4b. The cover 4b is located on the front side of the box body 4a, which makes it convenient to open the cover 4b to repair and replace the electrical control box 4 without having to disassemble the entire electrical control box 4. This improves disassembly and assembly efficiency and facilitates subsequent maintenance of the air conditioner 1000.

[0074] As shown in Figure 5, the fresh air component 5 includes a duct housing 5a and a fresh air fan (not shown in the figure). The duct housing 5a is located on the side of the fresh air fan near the ventilation and heat exchange component 3. The duct housing 5a defines an air inlet chamber 5a1 that communicates with the inlet of the fresh air fan. The duct housing 5a is located below the first box portion 4a1 and behind the second box portion 4a2. The duct housing 5a defines a second wall portion 51. The lower end of the second box portion 4a2 forms a third wall portion 41. The second wall portion 51 is located in front of the first wall portion 11, and the third wall portion 41 is located in front of the second wall portion 51. Therefore, the space utilization is high, and the arrangement of the fresh air component 5 and the electrical control box 4 is compact, which is beneficial to reducing the size of the air conditioner 1000 along the first direction F1.

[0075] The fresh air component 5 includes a duct housing 5a and a fresh air fan, which guides outdoor fresh air from the air inlet chamber 5a1 into the fresh air component 5. The duct housing 5a defines a second wall portion 51, and the lower end of the second box portion 4a2 of the electrical control box 4 forms a third wall portion 41. Fasteners 600 pass through the lower end of the duct housing 5a and the lower end of the second box portion 4a2 of the electrical control box 4 and are connected to the connecting structure 12 provided on the first wall portion 11, thereby connecting both the electrical control box 4 and the fresh air component 5 to the chassis 100.

[0076] The second wall portion 51 is located in front of the first wall portion 11, and the third wall portion 41 is located in front of the second wall portion 51, with the second wall portion 51 situated between the first wall portion 11 and the third wall portion 41. During assembly, the fresh air component 5 is first placed on the chassis 100, then the electrical control box 4 is placed on the fresh air component 5 and the chassis 100, and finally the electrical control box 4, the fresh air component 5, and the chassis 100 are fixedly connected.

[0077] In some embodiments of the present invention, as shown in FIG9, the upper end of the rear panel of the chassis 100 has a first limiting part 13, and the rear side of the first limiting part 13 forms a first limiting groove 131 with an open bottom. The upper rear side of the fresh air component 5 has a first pin 54 extending upward, the first pin 54 is inserted into the first limiting groove 131, and the first limiting part 13 stops at the front end of the first pin 54.

[0078] The fresh air component 5 and the chassis 100 are positioned by the insertion and mating of the first pin 54 and the first limiting groove 131. The fresh air component 5 is first positioned and mated with the chassis 100, and then fixedly connected to the chassis 100, which can improve assembly efficiency and assembly accuracy.

[0079] The fresh air component 5 is arranged on the front side of the chassis 100. After the first pin 54 is inserted into the first limiting groove 131, the first limiting part 13 stops at the front end of the first pin 54, thereby limiting the fresh air component 5 in the front-back direction, so that the fresh air component 5 and the chassis 100 are stably matched.

[0080] The lower end of the air duct shell 5a of the fresh air component 5 is fixedly connected to the chassis 100. Therefore, the upper side of the fresh air component 5 is provided with a first pin 54, and the fresh air component 5 is subjected to uniform force, which can improve the connection stability between the fresh air component 5 and the chassis 100.

[0081] As shown in Figure 9, the bottom of the first limiting groove 131 is open. When the first pin 54 is inserted into the first limiting groove 131, it is inserted from below and above. Since the opening of the first limiting groove 131 is relatively large, the insertion of the first pin 54 is relatively simple, and the first pin 54 can be inserted into the first limiting groove 131 at multiple angles. Then, the fresh air component 5 is rotated so that the first limiting part 13 stops at the front end of the first pin 54 and the second wall part 51 of the fresh air component 5 contacts the first wall part 11, thus completing the engagement between the fresh air component 5 and the chassis 100.

[0082] In some embodiments of the present invention, as shown in FIG9, the lower part of the rear panel of the chassis 100 has a support portion 15, the support portion 15 defines a front-opening groove 151, and the lower part of the fresh air component 5 extends rearward to form a support block 55, which is inserted into the groove 151.

[0083] The bottom of the first limiting groove 131 is open, and the engagement between the first limiting groove 131 and the first pin 54 cannot support the fresh air component 5, making it easy for the fresh air component 5 to slide downwards. Therefore, by providing a support block 55 at the lower rear side of the fresh air component 5, and by inserting the support block 55 into the groove 151 of the chassis 100, the fresh air component 5 is limited in the vertical direction relative to the chassis 100, and the connection stability between the fresh air component 5 and the chassis 100 can be further improved.

[0084] After the first pin 54 is inserted into the first limiting groove 131, the fresh air component 5 is rotated, and the support block 55 is inserted into the groove 151. At this time, the first limiting part 13 stops at the front end of the first pin 54, the support block 55 is inserted into the groove 151, and the second wall part 51 of the fresh air component 5 contacts the first wall part 11, thus completing the cooperation between the fresh air component 5 and the chassis 100.

[0085] In some embodiments of the present invention, as shown in FIG10, the upper end of the rear panel of the chassis 100 has a second limiting part 14, and the rear side of the second limiting part 14 forms a second limiting groove 141 with an open bottom. The upper rear side of the electrical control box 4 has an upwardly extending second pin 44, which is inserted into the second limiting groove 141, and the second limiting part 14 stops at the front end of the second pin 44.

[0086] The electrical control box 4 and the chassis 100 are positioned by the insertion and mating of the second pin 44 and the second limiting groove 141. After the electrical control box 4 is positioned and mated with the chassis 100, it is then fixedly connected to the chassis 100, which can improve assembly efficiency and assembly accuracy.

[0087] The electrical control box 4 is located on the front side of the chassis 100. After the second pin 44 is inserted into the second limiting groove 141, the second limiting part 14 stops at the front end of the second pin 44 to limit the electrical control box 4, thereby making the fresh air component 5 and the chassis 100 stably cooperate.

[0088] The lower end of the second box part 4a2 of the electrical control box 4 is fixedly connected to the chassis 100. Therefore, the upper side of the electrical control box 4 is provided with a second pin 44, and the electrical control box 4 is subjected to uniform force, which can improve the connection stability between the electrical control box 4 and the chassis 100.

[0089] As shown in Figure 10, the bottom of the second limiting groove 141 is open. When the second pin 44 is inserted into the second limiting groove 141, it is inserted from below and above. Since the opening of the second limiting groove 141 is relatively large, the insertion of the second pin 44 is relatively simple, and the second pin 44 can be inserted into the second limiting groove 141 at multiple angles. Then, the control box 4 is rotated so that the second limiting part 14 stops at the front end of the second pin 44 and the third wall part 41 of the control box 4 contacts the first wall part 11, thus completing the engagement between the control box 4 and the chassis 100.

[0090] The ventilation and heat exchange component 3, the electrical control box 4, and the fresh air component 5 are arranged sequentially along the length of the ventilation and heat exchange component 3. Therefore, as shown in Figure 7, the second limiting part 14, which cooperates with the electrical control box 4, is positioned close to the ventilation and heat exchange component 3 relative to the first limiting part 13, which cooperates with the fresh air component 5.

[0091] During assembly, first connect the first pin 54 of the fresh air component 5 to the first limiting groove 131, and then connect the second pin 44 of the electrical control box 4 to the second limiting groove 141.

[0092] The assembly process of the electrical control box 4, the fresh air component 5, and the chassis 100 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0093] First, position and connect the fresh air component 5 to the chassis 100.

[0094] Insert the first pin 54 at the upper rear end of the fresh air component 5 into the first limiting groove 131 of the chassis 100 from bottom to top; then rotate the fresh air component 5 and insert the support block 55 at the lower rear end of the fresh air component 5 into the groove 151 of the chassis 100.

[0095] As the fresh air component 5 rotates until the support block 55 is inserted into the groove 151, the sleeve portion 511 on the second wall portion 51 on the front side of the fresh air component 5 is fitted onto the threaded post 121a on the first wall portion 11 on the front side of the chassis 100. At this time, both the front and rear sides of the fresh air component 5 are positioned and engaged with the chassis 100, completing the positioning connection.

[0096] Next, the electrical control box 4 is positioned and connected to the chassis 100 and the fresh air component 5.

[0097] Insert the second pin 44 at the upper rear end of the control box 4 into the second limiting groove 141 of the chassis 100 from bottom to top. Then rotate the control box 4 so that the second positioning hole 411 of the third wall 41 on the front side of the control box 4 passes through the second protrusion 512 of the second wall 51 of the fresh air component 5, thereby completing the positioning of the control box 4 with the fresh air component 5 and the chassis 100.

[0098] Since the rear and front sides of the electrical control box 4 are already positioned, the through hole 42 on the third wall 41 of the electrical control box 4 can be accurately positioned opposite to the threaded post 121a.

[0099] Finally, simply pass the screw 6a through the through hole 42 from front to back and thread it to the threaded post 121a. The head of the screw 6a abuts against the side of the third wall 41 away from the first wall 11, and the electrical control box 4, the fresh air component 5 and the chassis 100 are fixedly connected.

[0100] In some embodiments of the present invention, the positioning and engagement are not limited to those described above; the fresh air component 5 and the electrical control box 4 are also positioned and engaged through other positioning components. This assembly method, which involves positioning before fixing, improves the assembly efficiency and connection accuracy of the fresh air component 5 and the electrical control box 4.

[0101] In some embodiments of the present invention, as shown in Figures 7 and 8, the ventilation and heat exchange component 3 includes a heat exchange assembly 31 and a fan assembly 32. The fan assembly 32 includes a cross-flow impeller 321 and a drive motor 322. The axial direction of the cross-flow impeller 321 is in the left-right direction. The drive motor 322 is connected to the side of the cross-flow impeller 321 near the fresh air component 5 in the axial direction. At least a portion of the drive motor 322 is located below the first box portion 4a1 and behind the second box portion 4a2.

[0102] At least a portion of the duct housing 5a and the drive motor 322 are opposite the electrical control box 4 in the front-rear direction, allowing at least a portion of the drive motor 322 to encroach upon the boundary area occupied by the electrical control box 4 in the left-right direction. This results in the stacking length of the ventilation and heat exchange component 3, the electrical control box 4, and the fresh air component 5 in the left-right direction being less than the sum of their individual left-right lengths. This reduces the left-right length of the air conditioner 1000, facilitating a miniaturized design and easier installation.
