[0002] The air conditioner outdoor unit is an important component of the air conditioning system. It is usually installed on the outside of the building. It discharges the hot air absorbed by the indoor unit to the outside and adjusts the indoor temperature through cooling or heating cycles. At the same time, the fan rotates driven by the motor to help air circulation, allowing heat to dissipate more quickly and maintain the normal operation of the outdoor unit.

[0003] Air conditioner outdoor units are typically installed outside buildings and exposed to the air for extended periods, making them susceptible to dust and other impurities. These impurities can enter the outdoor unit through the air vents, affecting its performance and reducing its cooling or heating efficiency. Conventional methods often involve installing dust covers on outdoor units. However, this requires manual installation when the air conditioner is not in use and removal before use, a cumbersome process.

[0004] Therefore, how to propose a more convenient dust prevention solution for outdoor units is an issue that needs to be urgently addressed in the industry. Summary of the Invention

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The outdoor unit of an air conditioner is a crucial component of an air conditioning system, typically installed outside a building. It discharges hot air absorbed by the indoor unit to the outside, regulating the indoor temperature through a cooling or heating cycle. Simultaneously, a fan, driven by a motor, rotates to circulate air, dissipating heat more quickly and maintaining the normal operation of the outdoor unit. Outdoor units are typically installed outside a building and exposed to the air for extended periods, making them susceptible to dust and other impurities. This can affect the performance of the outdoor unit and reduce its cooling or heating efficiency. Therefore, the present invention proposes a dust-proof device for an outdoor unit and an outdoor unit.

[0035] Please also refer to Figures 1 to 3 The outdoor unit dust prevention device proposed by the present invention includes:

[0036] The protective frame 1 has a hollow passage therein for being sleeved on the outdoor unit body 9;

[0037] The dust shield assembly 2 includes a blocking component located in the hollow channel and an opening and closing adjustment component arranged on the protective frame 1; the blocking component has a switchable open state and a closed state. When the opening and closing adjustment component drives the blocking component to switch to the closed state, it can prevent external dust from entering the interior of the outdoor unit body 9 through the hollow channel.

[0038] When using the outdoor unit dustproof device, a worker can attach the protective frame 1 to the outside of the outdoor unit body 9. When the outdoor unit is idle for an extended period, the blocking member can be switched to a closed position by operating the opening and closing adjustment member, effectively blocking external dust and providing dust protection for the outdoor unit. When the outdoor unit is needed, the blocking member can be switched to an open position by operating the opening and closing adjustment member, allowing the hollow passage within the protective frame 1 to communicate with the outside world and ensuring the normal operation of the outdoor unit. This invention not only effectively prevents dust accumulation within the outdoor unit body 9, but also eliminates the need for repeated disassembly and assembly of the dustproof device, making it easy to operate.

[0039] In a preferred embodiment of the present invention, Figure 3 As shown, the outdoor unit dustproof device further includes a dustproof net 805, which is located in the hollow channel and close to the side of the blocking component away from the outdoor unit body 9.

[0040] The present invention further adds a dustproof net 805, which can effectively filter and block dust in the air, thereby more effectively preventing external dust from entering the interior of the air conditioner outdoor unit, providing better dustproof protection for the air conditioner outdoor unit.

[0041] It should be noted that the air-conditioning outdoor unit is usually installed on the facade of a building, with its air inlet side close to the wall and its air outlet side away from the wall. In order to facilitate the installation of the outdoor unit dustproof device, the present invention preferably sleeves the dustproof device on the air outlet side of the outdoor unit body 9. When the air-conditioning outdoor unit is in an idle state, the dustproof net 805 can effectively filter dust in the air and prevent external dust from entering the interior of the air-conditioning outdoor unit, thereby enhancing the protection effect against external dust. In addition, in other optional embodiments, if the dustproof device is installed on the air inlet side of the outdoor unit body 9, regardless of whether the air-conditioning outdoor unit is in operation, the dustproof net 805 can continue to filter dust in the air and prevent external dust from entering the interior of the outdoor unit, further enhancing the protection against external dust.

[0042] In a preferred embodiment of the present invention, Figure 3As shown, the dust screen 805 is fixed inside the fixed frame 804. The top of the protective frame 1 is provided with a mounting slot 801 for the fixed frame 804 to pass through. Two guide rails 802 are provided on both sides of the interior of the protective frame 1. Each guide rail 802 is provided with a slide slot 803 that is slidably connected to the fixed frame 804. A first push-pull handle 806 is provided on the top of the fixed frame 804. By pulling the first push-pull handle 806, the fixed frame 804 and the dust screen 805 are pulled outward from the mounting slot 801, allowing staff to clean the dust screen 805. Then, using the sliding connection between the slide slot 803 and the fixed frame 804, staff can easily reinstall the fixed frame 804 and dust screen 805 inside the protective frame 1 to achieve the dustproof function.

[0043] The present invention further realizes a detachable design of the dustproof net 805, so that the staff can easily clean the dustproof net 805, thereby effectively improving the convenience and maintenance efficiency of the dustproof device.

[0044] In a preferred embodiment of the present invention, Figure 2 、 Figure 4 As shown, the blocking component includes a plurality of movable baffles 203 arranged in the hollow channel along the vertical direction; the opening and closing adjustment component includes:

[0045] Two adjustment rods 206 are movably arranged on both sides of the protective frame 1;

[0046] Two sets of connecting rod mechanisms are provided on both sides of the plurality of movable baffles 203, each set of connecting rod mechanisms including a plurality of connecting rod mechanisms for connecting the plurality of movable baffles 203 and one of the adjustment rods 206;

[0047] The second push-pull handle 6 is located outside the protective frame 1 and is connected to the upper ends of the two adjustment rods 206; by pulling the second push-pull handle 6, the two adjustment rods 206 move upward, thereby driving the two sets of connecting rod mechanisms to rotate the multiple movable baffles 203 upward, so that the blocking component is switched to a closed state.

[0048] When the air conditioner outdoor unit is in an idle state, the staff only needs to pull the second push-pull handle 6 to move the two adjustment rods 206 upward, thereby driving the two sets of connecting rod mechanisms to rotate the multiple movable baffles 203 upward, thereby closing the blocking component. This design is not only easy to operate, but also significantly improves the protection performance of the air conditioner outdoor unit. When the blocking component is in the closed state, these movable baffles 203 can tightly seal the hollow channel, effectively preventing dust and other debris from entering the interior of the outdoor unit body 9, thereby protecting it from damage. When the air conditioner outdoor unit needs to be used, the staff only needs to push the second push-pull handle 6 to move the two adjustment rods 206 downward, driving the two sets of connecting rod mechanisms to rotate the multiple movable baffles 203 downward, thereby opening the blocking component. This ensures smooth air circulation and does not affect the normal operation of the air conditioner outdoor unit. Through the opening and closing adjustment component of this structure, the staff can easily control the opening and closing of the blocking component, while ensuring efficient protection, also taking into account the convenience of use.

[0049] In a preferred embodiment of the present invention, Figure 4 、 Figure 5 As shown, a connecting groove 5 is provided on the top of the protective frame 1 for the upper ends of the two adjusting rods 206 to pass through. The upper ends of the two adjusting rods 206 are connected by a first shielding plate 3, and the first shielding plate 3 is used to shield the connecting groove 5 when the blocking component is in a closed state.

[0050] The present invention further takes into account that when the blocking component is in the closed state, if the connecting groove 5 is exposed to the outside, external dust may enter the interior of the protective frame 1 through the connecting groove 5, and then enter the interior of the outdoor unit body 9. To this end, the present invention uses the upper ends of the two adjustment rods 206 to be connected by a first shielding plate 3. When the staff pulls the second push-pull handle 6 to switch the blocking component to the closed state, the first shielding plate 3 will simultaneously move upward to the bottom notch of the connecting groove 5, thereby blocking the connecting groove 5. In this way, the first shielding plate 3 can effectively prevent external dust from entering the interior of the protective frame 1 through the connecting groove 5, thereby preventing it from entering the interior of the air conditioner outdoor unit, further enhancing the protection effect against external dust. At the same time, it can also effectively protect the components around the connecting groove 5 (such as the connecting rod mechanism, etc.), thereby improving the practicality and durability of the outdoor unit dustproof device.

[0051] In a preferred embodiment of the present invention, Figure 4 、 Figure 5 As shown, the upper ends of the two adjusting rods 206 are also connected to the second push-pull handle 6 through the second shielding plate 4. The second shielding plate 4 is used to shield the connecting groove 5 when the blocking component is in the open state.

[0052] The present invention also enhances the overall structural stability by connecting the upper ends of the two adjustment rods 206 to the second shielding plate 4, combined with the second push-pull handle 6. When a worker pushes the second push-pull handle 6 to switch the blocking member to the open position, the second shielding plate 4 simultaneously moves downward to the top notch of the connecting slot 5, thereby shielding the connecting slot 5. In this way, the second shielding plate 4 effectively prevents dust, rainwater, and other debris from entering the protective frame 1 through the connecting slot 5, effectively protecting the surrounding components of the connecting slot 5 (such as the connecting rod mechanism), thereby enhancing the practicality and durability of the outdoor unit's dustproof device.

[0053] In a preferred embodiment of the present invention, Figure 2 、 Figure 6 As shown, the dust shield assembly 2 also includes two limiting components 7 for limiting the two adjustment rods 206, and a third push-pull handle 705 connecting the two limiting components 7. The two limiting components 7 are symmetrically distributed on the top of the protective frame 1. Each limiting component 7 includes a connecting frame 701 arranged on the top of the protective frame 1, an elastic element 702 arranged inside the connecting frame 701, a connecting block 703 connected to the third push-pull handle 705 and the elastic element 702, and a limiting block 704 arranged at one end of the connecting block 703 away from the elastic element 702 and capable of abutting against the second shielding plate 4; by pushing the third push-pull handle 705, the connecting block 703 moves in the direction of compressing the elastic element 702, thereby separating the limiting block 704 from the second shielding plate 4, thereby releasing the limit on the two adjustment rods 206. Among them, the elastic element 702 is preferably a spring.

[0054] The present invention further adds two limiting components 7 and a third push-pull handle 705. By pushing the third push-pull handle 705, the staff member moves the connecting block 703 in the direction of the compressed elastic element 702, thereby separating the limiting block 704 from the first baffle plate 3, and releasing the limit on the two adjustment rods 206. Subsequently, the staff member can adjust the two adjustment rods 206 through the second push-pull handle 6 to change the opening and closing state of the blocking component. When the opening and closing state of the blocking component is switched, under the elastic force of the elastic element 702, the connecting block 703 and the limiting block 704 will move in the direction of the stretched elastic element 702, so that the limiting block 704 is in close contact with the second baffle plate 4, thereby limiting the two adjustment rods 206. This design effectively prevents the adjustment rod 206 from accidentally moving due to vibration or other factors during the operation of the air-conditioning outdoor unit, thereby changing the opening and closing state of the blocking component, thereby improving the stability and reliability of the outdoor unit's dustproof device.

[0055] In a preferred embodiment of the present invention, Figure 4 、 Figure 7As shown, each connecting rod mechanism includes a support rod 201 connected to the inside of the protective frame 1, a first rotating frame 202 connected to the movable baffle 203 and rotatably connected to the support rod 201, a support frame 204 connected to the movable baffle 203, and a second rotating frame 207 connected to the adjusting rod 206 and rotatably connected to the support frame 204.

[0056] When a staff member pulls the second push-pull handle 6 to move the adjustment rod 206 upward, the adjustment rod 206 drives the second turret 207 upward. Because a rotational connection is provided between the second turret 207 and the support frame 204, and between the support rod 201 and the first turret 202, the second turret 207, during its ascent, causes the movable baffle 203 to rotate upward via the support frame 204, thereby closing the movable baffle 203 and switching the blocking member to its closed state. Conversely, when a staff member pushes the second push-pull handle 6 to move the adjustment rod 206 downward, the adjustment rod 206 drives the second turret 207 downward. Similarly, due to the rotational connections between the second turret 207 and the support frame 204, and between the support rod 201 and the first turret 202, the second turret 207, during its descent, causes the movable baffle 203 to rotate downward via the support frame 204, thereby opening the movable baffle 203 and switching the blocking member to its open state. This linkage mechanism has a simple structure and is easy to maintain. During the upward and downward movement of the adjusting rod 206 , the opening and closing of the movable baffle 203 is achieved through the transmission action of the connecting rod mechanism.

[0057] Please also refer to Figures 1 to 3 The present invention also provides an air conditioner outdoor unit, comprising an outdoor unit body 9 and an outdoor unit dustproof device sleeved onto the outdoor unit body 9. The specific structure of the outdoor unit dustproof device has been described in detail above and will not be repeated here. The outdoor unit dustproof device equipped with this air conditioner outdoor unit not only effectively prevents dust accumulation within the outdoor unit body 9 but also eliminates the need for frequent disassembly and assembly, offering the advantage of ease of operation. This improves the performance of the air conditioner outdoor unit.

[0058] In a preferred embodiment of the present invention, Figure 3 As shown, the outdoor unit dustproof device is sleeved onto the air outlet side of the outdoor unit body 9. Typically, there is more space around the air outlet side of the outdoor unit body 9, which facilitates installation of the outdoor unit dustproof device. By sleeved onto the air outlet side of the outdoor unit body 9, when the air conditioner outdoor unit is idle, the outdoor unit dustproof device effectively prevents external dust from entering the outdoor unit body 9 from the air outlet side, thereby ensuring that the performance of the air conditioner outdoor unit is not affected.

[0059] For a clearer understanding, the working principle of the outdoor unit dust prevention device during use proposed in the preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0060] Please also refer to Figures 3 to 7 When using the outdoor unit dustproof device, the staff first attaches the protective frame 1 to the air outlet side of the outdoor unit body 9. Next, the staff pulls the connecting block 703 forward using the third push-pull handle 705, causing the connecting block 703 to drive the limiting block 704 to move forward from the bottom of the second shielding plate 4. Subsequently, the staff pushes the adjustment rod 206 downward using the second push-pull handle 6, causing the adjustment rod 206 to drive the second rotating frame 207 downward. Through the rotational connection between the second rotating frame 207 and the support frame 204, and the rotational connection between the support rod 201 and the first rotating frame 202, the second rotating frame 207 moves downward and drives the movable baffle 203 to rotate downward through the support frame 204, thereby opening the movable baffle 203. At the same time, the second shielding plate 4 moves to the top notch of the connecting slot 5 for protection, ensuring that the outdoor unit body 9 can function normally.

[0061] When the outdoor unit body 9 is not in use for an extended period, a worker can pull the adjustment rod 206 upward using the second push-pull handle 6. This causes the adjustment rod 206 to drive the support frame 204 upward via the second rotating frame 207, thereby flipping the movable baffle 203 upward and closing it, ensuring that the movable baffle 203 can effectively block external dust. Simultaneously, the first shielding plate 3 moves to the bottom notch of the connecting slot 5 for protection. Furthermore, in the limiting component 7, the elastic force of the elastic element 702 pushes the connecting block 703 and the limiting block 704 backward, causing the limiting block 704 to limit the position of the second shielding plate 4, thereby limiting the adjustment rod 206.

[0062] Furthermore, when the outdoor unit body 9 is not in use for an extended period, the dust screen 805 filters and blocks dust from the air, further preventing dust from entering the interior of the outdoor unit body 9. A worker can use the first push-pull handle 806 to pull the fixing frame 804 and the dust screen 805 outward from the center of the mounting slot 801 to clean the dust screen 805. Then, through the sliding connection between the slide slot 803 and the fixing frame 804, the worker can reinstall the fixing frame 804 into the interior of the protective frame 1 to continue dust prevention work.
