Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit technology, specifically an air conditioner outdoor unit with a detachable fan cover. Background Technology

[0002] The outdoor unit fan cover is an important component of the air conditioner's outdoor unit. Its main functions are to protect the fan and motor, prevent external objects from entering, and ensure airflow and heat dissipation. Over time, the outdoor unit fan cover will accumulate a lot of dust and other impurities, requiring regular cleaning to avoid affecting the air conditioning unit's ventilation and heat dissipation.

[0003] Existing outdoor unit fan covers are generally welded directly to one side of the outdoor unit casing or fixed with multiple bolts, with the fan housing close to the interior of the outdoor unit. However, welding the fan cover to the casing makes cleaning inconvenient; the fan cover is connected to the casing with multiple bolts in different locations, making disassembly cumbersome. Furthermore, residential or commercial outdoor units are typically installed on high-altitude balconies where space is limited, making it difficult for maintenance personnel to quickly disassemble and clean the fan cover within a short timeframe. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides an air conditioner outdoor unit with a detachable fan cover.

[0005] The technical solution of this utility model is as follows:

[0006] An outdoor air conditioner unit with a detachable fan cover includes a housing and a fan cover. A cooling fan is provided inside the housing. The housing has a mounting port adapted to the fan cover on the side near the cooling fan. Mounting plates are provided at the corners of the mounting port. The mounting plates are located inside the housing. The fan cover is located outside the mounting plates. The fan cover is detachably mounted on the mounting port by multiple sets of locking units. The multiple sets of locking units are distributed at different corners of the mounting port.

[0007] The locking unit includes a stop plate, a slide rail, and a slide rod that slides on the slide rail. The slide rail is located inside the housing and near the corner of the mounting opening. The stop plate is located outside the fan cover and fits against the outer surface of the fan cover. One end of the slide rod passes through the housing and is connected to the stop plate. The other end of the slide rod is connected to the slide rail through an elastic element, which can be an elastic sheet or a compression spring. Under normal conditions, the stop plate is located outside the fan cover and fits against the fan cover, thus limiting the position of the fan cover.

[0008] Multiple locking units can press the fan cover firmly onto the mounting opening of the housing. The mounting plate can limit the corners of the fan cover, preventing it from tilting inwards. When installing or removing the fan cover, push the stop plate to one side, install the fan cover in the mounting opening, and then release the stop plate. The stop plate will return to its original position under the action of the elastic element, located on the outer corner of the fan cover, thus limiting its tilt and preventing it from tilting outwards. The operation is simple, facilitating quick installation and removal of the fan cover and easy cleaning.

[0009] The vertical distance between the outer surface of the mounting plate and the outer surface of the housing where the mounting opening is located is greater than the thickness of the slide rod. The mounting plate is located inside the housing, which facilitates the installation of the locking unit's slide rail and part of the slide rod inside the housing, resulting in a more aesthetically pleasing appearance and preventing it from protruding outside the housing.

[0010] The connection structure between the mounting plate and the housing is as follows: the mounting plate and the housing are connected by a connecting plate, and the connecting plate has an opening at the corner near the mounting opening that is compatible with the slide rod and the stop plate.

[0011] Regarding the specific structure of the stop plate, the stop plate is an arc-shaped plate, and its curvature is consistent with the curvature of the corner of the fan cover. This makes it easier to increase the contact area between the stop plate and the outer surface of the fan cover, and to make it easier to fix the fan cover. The arc-shaped plate has a chamfer on one of its arc-shaped edges near the fan cover. The chamfer makes it easier to quickly separate the fan cover from the arc plate when disassembling the fan cover.

[0012] To facilitate the stable pressing of the fan cover onto the mounting plate and reduce the large gap between the fan cover and the mounting plate, a tightening member is threaded onto the arc-shaped plate, with one end of the tightening member passing through the arc-shaped plate and contacting the mounting plate.

[0013] To facilitate the removal or installation of the fan cover by moving the stop plate to one side, a handle is provided on the side of the arc plate away from the mounting plate, with the handle located near the side of the arc plate away from the slide bar.

[0014] Regarding the location of the locking units, there are two sets of locking units, located at the two corners of the upper part of the mounting port. The lower part of the fan cover is connected to the lower part of the mounting port via a connector. By setting only two sets of locking units, the number of locking units is reduced, making it easier to quickly disassemble the fan cover. Furthermore, the lower part of the fan cover is hinged to the housing, which facilitates the quick disassembly of the lower part of the fan cover after removing the two upper locking units.

[0015] The above-mentioned connector has the following structure: the connector includes a mating connector shaft and a sleeve. The connector shaft is arranged horizontally at the lower part of the fan cover. Both ends of the connector shaft are connected to the fan cover through connectors. The connector shaft is inserted into the sleeve.

[0016] The specific structure of the sleeve is as follows: the sleeve is made of a rigid elastic material, and an arc-shaped disassembly port is opened on the upper part along the axial direction. The arc length of the arc-shaped disassembly port is less than half of the arc length of the plug shaft. The sleeve is provided with an arc-shaped disassembly port, so that the arc-shaped disassembly port can be passively opened, making it easy to put the plug shaft into or take it out of the sleeve.

[0017] The beneficial effects of this utility model are as follows:

[0018] Locking units are installed on both sides of the upper part of the mounting port. The upper part of the fan cover is locked by the stop plate of the locking unit. The fan cover can be limited by the stop plate to the mounting plate located inside the housing. The lower part of the fan cover can be locked to the lower part of the mounting port by two sets of locking units, or it can be connected by a plug-in connector. It is convenient to adjust the two upper locking units to the fan cover disassembly state, and then directly lift the fan cover. The plug-in shaft is disengaged from the sleeve to complete the disassembly of the fan cover. Then it can be cleaned. The disassembly method is simple and quick, and it is suitable for installing and disassembling the fan cover of the outdoor unit of the air conditioner on a narrow outdoor balcony.

[0019] The curved plate is threaded with a clamping member. One end of the clamping member passes through the curved plate and abuts against the mounting plate, which makes it easy to press the fan cover firmly onto the mounting plate and reduce the large gap between the fan cover and the mounting plate.

[0031] See Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, an outdoor air conditioner unit with a detachable fan cover includes a housing 1 and a fan cover 2. A cooling fan 14 is provided inside the housing 1. The housing 1 has a mounting port 101 that is adapted to the fan cover 2 on the side near the cooling fan 14. Mounting plates 3 are provided at the corners of the mounting port 101. The outer surface of the mounting plate 3 is parallel to the outer surface of the housing 1 on the side where the mounting port 101 is provided. The mounting plate is located inside the housing 1. The mounting plate 3 is connected to the housing 1 through a connecting plate 8.

[0032] The fan cover 2 is located on the outside of the mounting plate 3. In this embodiment, the fan cover 2 is detachably mounted on the mounting port 101 via two sets of locking units. The two locking units are distributed at the upper corners of the mounting port 101 to fix the upper sides of the fan cover 2 to the mounting port 101. In this embodiment, the lower part of the fan cover 2 is connected to the lower part of the mounting port 101 via a connector. Only two sets of locking units are provided, reducing the number of locking units and facilitating quick disassembly of the fan cover 2. Furthermore, the lower part of the fan cover 2 is hinged to the housing 1, facilitating quick disassembly of the lower part of the fan cover 2 after removing the two upper locking units.

[0033] See Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the locking unit includes a stop plate 4, a slide rail 5, and a slide rod 6 slidably connected to the slide rail 5. The slide rail 5 is inclined and located inside the housing 1 near the corner of the mounting opening 101. The stop plate 4 is located outside the fan cover 2 and fits against the outer surface of the fan cover 2. The slide rail 5 has a groove, and the slide rod 6 is slidably connected to the groove. One end of the slide rod 6 passes through the housing 1 and is connected to the stop plate 4, and the other end of the slide rod 6 is connected to the slide rail 5 through an elastic element 7. The connecting plate 8 has an opening 1201 near the corner of the mounting opening 101 that is adapted to the slide rod 6 and the stop plate 4. The slide rod 6 and the stop plate 4 can move inward to the inside of the housing 1 under the action of external force, which facilitates the movement of the stop plate 4 to the inside of the housing 1 without obstructing the disassembly of the fan cover 2.

[0034] The vertical distance between the outer surface of the mounting plate 3 and the outer surface of the housing 1 where the mounting opening 101 is located is greater than the thickness of the slide rod 6. The mounting plate 3 is located inside the housing 1, which makes it easier to install the slide rail 5 of the locking unit and part of the slide rod 6 inside the housing 1. This is more aesthetically pleasing and will not protrude outward from the outside of the housing 1.

[0035] See Figure 1 , Figure 3 and Figure 4 As shown, the connector in this embodiment includes a mating connector shaft 11 and a sleeve 13. The connector shaft 11 is horizontally positioned at the lower part of the fan cover 2, and both ends of the connector shaft 11 are connected to the fan cover 2 via connectors 12. The connector shaft 11 is inserted into the sleeve. Regarding the specific structure of the sleeve 13, the sleeve 13 is made of a rigid, elastic material, and its upper part has an arc-shaped disassembly opening 1301 along the axial direction. The arc length of the arc-shaped disassembly opening 1301 is less than half the arc length of the connector shaft 11. The arc-shaped disassembly opening 1301 on the sleeve 13 allows it to be passively opened, facilitating the insertion or removal of the connector shaft 11 within the sleeve 13.

[0036] In the above structure, the fan cover 2 can be pressed against the mounting port 101 of the housing 1 by two sets of locking units. The mounting plate 3 can limit the corners of the fan cover 2 to prevent the fan cover 2 from tilting inward to the housing 1. When it is necessary to install or remove the fan cover 2, push the stop plate 4 to one side, install the fan cover 2 in the mounting port 101, and then release the stop plate 4. The stop plate 4 will be reset under the action of the elastic element 7 and located on the outside of the corners of the fan cover 2 to limit the fan cover 2 and prevent the fan cover 2 from tilting outward to the housing 1. The operation is simple and facilitates the quick installation and removal of the fan cover 2, as well as quick cleaning.

[0037] See Figure 1 , Figure 2 and Figure 8 As shown, regarding the specific structure of the stop plate 4, the stop plate 4 is an arc-shaped plate, and its curvature is consistent with the curvature of the corner of the fan cover 2, which facilitates increasing the contact area between the stop plate 4 and the outer surface of the fan cover 2, making it easier to fix the fan cover 2. The arc-shaped plate has a chamfer 401 on one arc-shaped edge near the fan cover 2. The chamfer 401 facilitates the quick separation of the fan cover 2 from the arc-shaped plate when disassembling the fan cover 2.

[0038] To facilitate the stable pressing of the fan cover 2 onto the mounting plate 3 and reduce the large gap between the fan cover 2 and the mounting plate 3, a tightening member is threaded onto the arc plate, with one end of the tightening member passing through the arc plate and contacting the mounting plate 3.

[0039] A handle 10 is provided on the side of the arc plate away from the mounting plate 3. The handle 10 is close to the side of the arc plate away from the slide bar 6, which makes it easy to move the stop plate 4 to one side to remove or install the fan cover 2.
