Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

The present invention proposes a casing 1 of an air-conditioning outdoor unit. Please refer to Figures 1 to 6. In an embodiment of the present invention, the casing 1 of the air-conditioning outdoor unit includes a shell 10 and a front panel assembly 20. The shell 10 is provided with a fan cavity 18 and a compressor cavity 19. The fan cavity 18 is used to install components such as a fan 5 and a heat exchanger. The compressor cavity 19 is used to install components such as a compressor, a circuit board, a plate exchanger, pipelines and valves.

It should be noted that, in actual applications, the fan chamber 18 and the compressor chamber 19 can be interconnected, and there are various ways of connection. It can be that interconnected channels are formed inside the shell 10, or that a channel is connected outside the shell 10 to connect the fan chamber 18 and the compressor chamber 19 to each other. This arrangement allows the fan 5 to take away the heat in the compressor chamber 19 and play a role in heat dissipation.

The housing 10 is provided with an air inlet 141 and an air outlet 131 connected to the fan chamber 18, and the housing 10 is also provided with a maintenance window 171 connected to the compressor chamber 19. In this embodiment, the air outlet 131 is circular corresponding to the running track of the fan blades of the fan 5. While ensuring the smooth exhaust of the fan 5, the air outlet 131 is made smaller, which can ensure the strength of the housing 10 and enhance the overall stability. In addition, the air outlet 131 can be provided with a curved surface with a slope extending toward the center of the air outlet 131 in the housing 10, so as to reduce the entry of rainwater into the fan chamber 18. The air inlet 141 is in a grid shape, which can ensure the air intake of the fan chamber 18 and protect the interior of the fan chamber 18.

The maintenance window 171 is square and can be used to observe the components in the compressor cavity 19 from the outside. The mainboard and other electrical components in the compressor cavity 19 can also be maintained and replaced through the maintenance window 171. Of course, it is understandable that a detachable transparent panel can be provided on the maintenance window 171, which is convenient for observation and can better protect the compressor cavity 19 from external dust, water vapor, etc. The present invention does not specifically limit the specific shapes of the air inlet 141, the air outlet 131 and the maintenance window 171, which can be square, round, diamond, etc.

The front panel assembly 20 includes a first panel 21 and a second panel 22. The first panel 21 is connected to the housing 10 and covers the air outlet 131. The first panel 21 is provided with a vent 211 connected to the air outlet 131. The connection between the first panel 21 and the housing 10 includes but is not limited to bonding, welding, threaded connection, and snap-on connection. The materials of the first panel 21 and the second panel 22 may include but are not limited to plastic, metal, and other materials.

The first panel 21 is provided with a plurality of holes to form ventilation holes 211. The plurality of holes make the first panel 21 present as a flat grid structure. The shape of the holes can be various shapes, such as diamond, triangle, circle, square, etc., wherein the hot air can be discharged from the air outlet 131 through the ventilation holes 211. Of course, it can be understood that the first panel 21 can be similar in shape to the air outlet 131, just completely covering the air outlet 131, or can be larger than the air outlet 131, and integrated with the housing 10 to make the air conditioner outdoor unit more beautiful.

The second panel 22 is rotatably connected to the first panel 21, and the second panel 22 rotates relative to the first panel 21 to open or cover the maintenance window 171. It is also understandable that there are multiple ways to rotatably connect the second panel 22 to the first panel 21, which can be achieved by installing a hinge between the first panel 21 and the second panel 22, or by installing a rotatable connecting shaft between the first panel 21 and the second panel 22. The second panel 22 can be similar in shape to the maintenance window 171, just completely covering the maintenance window 171, or it can be larger than the maintenance window 171, and integrated with the housing 10 to make the air conditioner outdoor unit more beautiful.

Among them, the fixing area of the first panel 21 and the shell 10 is relatively wide. This arrangement improves the stability of the first panel 21 and the shell 10 and can withstand a heavier front panel assembly 20. The front panel assembly 20 can be suitable for large-capacity units (large-capacity units mean that the area of the front panel assembly 20 is larger). It solves the technical problem in conventional designs that the heavier the front assembly panel 20 is, the more screws are needed in the shell 10, and the more installation steps are required. This improves the installation efficiency and the adaptability of the front panel assembly 20.

According to the above scheme, the present invention sets a housing 10 having a fan cavity 18 and a compressor cavity 19 in the casing 1 of the air conditioner outer unit, and sets an air inlet 141 and an air outlet 131 connected to the fan cavity 18 and a maintenance window 171 connected to the compressor cavity 19 in the housing 10. Air with a relatively low external temperature can enter the housing 10 through the air inlet 141, and be discharged to the outside through the air outlet 131 after absorbing the internal heat of the housing 10. The front panel assembly 20 is set as a first panel 21 and a second panel 22 connected in rotation. The first panel 21 is provided with a ventilation hole 211. The first panel 21 is connected to the housing 10 and covers the air outlet 131. In this way, the first panel 21 can protect the interior of the fan cavity 18 and prevent foreign objects from interfering with or colliding with the components inside the fan cavity 18. At the same time, the second panel 22 is hung on the housing 10. In this way, the second panel 22 rotates relative to the first panel 21, covers the maintenance window 171, protects the interior of the compressor cavity 19, and prevents foreign objects from interfering with or colliding with the components inside the compressor cavity 19. When the interior of the compressor chamber 19 needs maintenance and care, the second panel 22 is rotated to open the maintenance window 171, so that the situation inside the compressor chamber 19 can be directly observed through the maintenance window 171, and the integrity of the internal parts of the compressor chamber 19 can be visually checked. The internal parts of the compressor chamber 19 can also be replaced and repaired through the maintenance window 171. There is no need to remove the front panel as a whole, which facilitates the maintenance of the air conditioner outdoor unit. Moreover, only the second panel 22 needs to be rotated, which reduces the gravity on the rotating connection, makes it easy to open, and the operating space required for rotating the second panel 22 is smaller.

As shown in Fig. 5 and Fig. 7, the front panel assembly 20 further includes a fixed shaft 23 and two rotating seats 24, the fixed shaft 23 is fixedly connected to the first panel 21, the two rotating seats 24 are installed at intervals on the second panel 22, and the rotating seats 24 are all rotatably connected to the fixed shaft 23. As an example, the two rotating seats 24 are located at both ends of the length direction of the fixed shaft 23, the second panel 22 is rotatably connected to the fixed shaft 23 through the two rotating seats 24, and the fixed shaft 23 is fixedly connected to the first panel 21. In this way, the second panel 22 can form a rotatable active connection with the first panel 21 through the two rotating shafts 24. Among them, there can be multiple ways to fix the fixed shaft 23 to the first panel 21, such as welding, interference fit, bonding, threaded connection, clamping, etc. The way that the two rotating seats 24 are installed at intervals on the second panel 22 can be a detachable fixed connection, such as threaded connection, clamping, or a non-detachable fixed connection, such as bonding, clamping.

The two rotating shafts 24 are located at both ends of the fixed shaft 23 in the length direction. The two rotating seats 24 can disperse the gravity of the second panel 22 to the fixed shaft 23, so as to avoid the fixed shaft 23 from being broken due to excessive force locally, and reduce the material hardness requirements for the fixed shaft 23. In another setting form, more rotating seats 24 can also be set. For example, three rotating seats 24 can be set to evenly divide the fixed shaft 23 into three parts in the length direction, and the three rotating seats 24 are arranged at intervals in the three parts of the fixed shaft 23, which is conducive to increasing the stability of the rotating seats 24 and the fixed shaft 23. The materials of the two rotating seats 24 and the fixed shaft 23 can include but are not limited to plastics, metals and other materials, and materials with appropriate hardness are sufficient.

5 and 7, arc guide surfaces 27 are provided on the two edges of the fixed shaft 23 and the two rotating seats 24 away from the housing 10. The arrangement of the arc guide surfaces 27 allows the second panel 22 to rotate relative to the first panel 21, leaving a certain rotation space for the rotating seat 24, so as to avoid the mounting platform 241 of the second panel 22 from interfering with the first panel 21 when the first panel 21 rotates. When the air conditioner outdoor unit is washed by rain, the arc guide surfaces 27 can also play a role in draining the rain, thereby reducing the corrosion of the air conditioner outdoor unit by rain, and its appearance is also more beautiful.

As shown in Figures 5 to 10, pivot holes 231 are recessed on both end surfaces of the fixed shaft 23 in the length direction. The pivot holes 231 are holes similar to cylindrical shapes. Each rotating seat 24 includes a mounting platform 241 and a pivot shaft 243. In the present embodiment, each mounting platform 241 is provided with a locking hole 245. The locking hole 245 is fixedly connected to the second panel 22 by screwing. One end of each pivot shaft 243 is connected to the corresponding mounting platform 241, and the other end of each pivot shaft 243 is rotatably connected to the pivot hole 231 at the corresponding end.

There are many ways to connect the mounting platform 241 and the pivot shaft 243. In one setting, a shaft mounting hole is opened at one end of each mounting platform 241 connected to the pivot shaft 243. After the pivot shaft 243 is inserted into the shaft mounting hole, it is welded. This setting can firmly fix the pivot shaft 243 to the mounting platform 241, and ensure that the axial direction of the pivot shaft 243 is parallel to the mounting platform 241, which also reduces the processing difficulty.

In another arrangement, the pivot shaft 243 is threadedly engaged with the shaft mounting hole. Of course, it is understandable that the pivot shaft 243 and the mounting platform 241 can be integrally formed parts, which can reduce the requirements of the installation process and enhance the stability of the structure.

In this embodiment, the fixed shaft 23 and the two rotating seats 24 are located between the first panel 21 and the second panel 22. In this way, when the second panel 22 covers the maintenance window 171, the connection between the fixed shaft 23 and the first panel 21 can be hidden between the first panel 21 and the second panel 22. Similarly, the connection between the two rotating seats 24 and the second panel 22 can also be hidden between the first panel 21 and the second panel 22. In this way, when the air conditioner outdoor unit is exposed to rain, it cannot penetrate, avoiding the risk of rusting of metal installation parts.

Furthermore, a limit groove 244 is recessed on the outer wall of each pivot shaft 243, and each limit groove 244 is extended along the circumference of the corresponding pivot shaft 243. The front panel assembly 20 also includes two limit pins 25, and the two limit pins 25 are respectively arranged at both ends of the fixed shaft 23 in the length direction. The two limit pins 25 are at least partially located in the corresponding limit groove 244 to limit the corresponding pivot shaft 243 from being separated from the corresponding pivot hole 231, so that each rotating seat 24 is stably rotatably connected to the corresponding end of the fixed shaft 23 without any risk of separation, further ensuring the stability of the rotational connection between the first panel 21 and the second panel 22, and can improve the reliability of rotating the second panel 22 to open or cover the maintenance window 171.

In this embodiment, the outer wall of each pivot shaft 243 is recessed with an annular limiting groove 244 with a semicircular cross-section. Of course, in other embodiments, the cross-section of the limiting groove 244 can be in other shapes, such as a square, and the limiting pin 25 corresponding to the limiting groove 244 is cylindrical.

The installation of the limit pin 25 can be done by opening a through hole connected to the pivot hole 231 on the circumference of the fixed shaft 23, and the limit pin 25 and the through hole have a clearance fit or an interference fit. Alternatively, a through hole penetrating the fixed shaft 23 and passing through the pivot hole 231 can be opened on the circumference of the fixed shaft 23, and the aperture of the through hole can be gradually reduced, and the outer diameter of the corresponding limit pin 25 is also gradually reduced, so that the installation of the limit pin 25 is convenient and it is not easy to fall off.

The cooperation between the limiting pin 25 and the limiting groove 244 limits the axial movement of the pivot shaft 243, prevents the pivot shaft 243 from being separated from the corresponding pivot hole 231, and improves the reliability of the rotation connection.

Please refer to Figures 8, 9 and 10. Both end surfaces of the fixed shaft 23 in the length direction are recessed with avoidance holes 232. Each avoidance hole 232 is also connected to the pivot hole 231 on the corresponding side. Each limit pin 25 extends into the avoidance hole 232 along the width direction or thickness direction of the fixed shaft 23. The part of each limit pin 25 located in the corresponding avoidance hole 232 also cooperates with the limit groove 244 on the corresponding pivot shaft 243.

Preferably, the cross-sectional width of the connecting portion between the avoidance hole 232 and the pivot hole 231 is smaller than the diameter of the pivot shaft 243, that is, the pivot hole 231 still retains more than half of the arc. In this way, the pivot shaft 243 can partially extend into the avoidance hole 232 through the connecting portion between the pivot hole 231 and the avoidance hole 232, and the limiting pin 25 can be attached to the hole wall of the avoidance hole 232 or embedded in the hole wall of the avoidance hole 232 to extend the avoidance hole 232 and cooperate with the limiting groove 244, making the structure more compact, saving materials and light weight, and also making the installation process clear at a glance, improving the installation efficiency. Of course, the fixed shaft 23 can also be set as a hollow structure.

Furthermore, one end surface of the fixed shaft 23 in the length direction is recessed with a limiting hole 233, and the limiting hole 233 is located on the circumferential side of the pivot hole 231 on the corresponding side. The limiting hole 233 is also extended along the circumferential direction of the pivot hole 231 on the corresponding side. The mounting platform 241 adjacent to the limiting hole 233 of the two mounting platforms 241 is provided with a limiting protrusion 242, and the limiting protrusion 242 extends into the limiting hole 233 and is clearance-matched with the limiting hole 233.

In this embodiment, the setting of the limiting hole 233 and the above-mentioned avoidance hole 232 can be set as the same hole. Of course, it can be understood that the limiting hole 233 can also be set separately on the end surface of the fixed shaft 23. The setting method of the limiting protrusion 242 is also similar to the connection method between the above-mentioned pivot shaft 243 and the mounting platform 241, which can be welding, threaded connection, integral molding, etc., which will not be repeated here.

The limiting protrusion 242 is limited to move between the two hole walls of the avoidance hole 232 to limit the rotation angle of the mounting platform 241 relative to the fixed shaft 23, thereby limiting the opening range of the second panel 22 to avoid interference with the first panel 21. The opening range of the second panel 22 can be adjusted according to the distance between the limiting protrusion 242 and the pivot shaft 243 or the circumferential width of the limiting hole 233, that is, the farther the distance between the limiting protrusion 242 and the pivot shaft 243, the larger the opening range, the smaller the circumferential width of the limiting hole 233, and vice versa.

In the present embodiment, the front panel assembly 20 can be installed separately and then connected to the housing 10. With this arrangement, the front panel assembly 20 is installed in a separate, modular manner, so that the installation of the front panel assembly 20 is not affected by other components of the air conditioner outdoor unit (for example, in conventional designs, the front assembly panel 20 and the upper cover 12 are fixedly matched). It is only necessary to install the first panel 21 of the front panel assembly 20 on the housing 10 of the air conditioner outdoor unit to complete the installation process, thereby improving the installation efficiency of the air conditioner outdoor unit.

Specifically, the two rotating seats 24 are rotatably connected to the two ends of the fixed shaft 23 in the length direction through the pivot shaft 243, and a through hole connected to the pivot hole 231 is opened in the circumference of the fixed shaft 23. The limiting pin 25 is inserted into the pivot hole 231 through the through hole and cooperates with the limiting groove 244 of the pivot shaft 243, so that the second panel 22 is rotatably connected to the fixed shaft 23 through the two rotating seats 24. After the second panel 22 and the fixed shaft 23 are installed, the second panel 22 is turned over and the first panel 21 is installed on the fixed shaft 23 by screwing, and the installation of the front panel assembly 20 is completed. When the front panel assembly 20 needs to be installed on the housing 10 of the air conditioner outdoor unit, it is only necessary to fix the first panel 21 of the front panel assembly 20 to the housing 10 of the air conditioner outdoor unit to complete the installation. Preferably, the first panel 21 is provided with four holes at intervals and fixed to the housing 10 by screwing.
