Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an outdoor air conditioner unit and an air conditioner having the outdoor air conditioner unit. Background Technology

[0002] As people's demands for quality of life and comfort continue to rise, air conditioners, as important household appliances, are receiving increasing attention from consumers. The outdoor unit of an air conditioner is typically installed outdoors. Because it is constantly exposed to the outdoors, dust, debris, and dirt can directly enter the unit through the grille vents. These dust, debris, and dirt accumulate on the blades of the outdoor fan, increasing the fan load and thus energy consumption. Furthermore, dust, debris, and dirt accumulate on the outdoor heat exchanger, reducing heat exchange efficiency and affecting the normal operation of the air conditioner. In addition, cleaning existing outdoor air conditioner units usually requires professional maintenance personnel, increasing maintenance costs for users and causing inconvenience.

[0003] An existing air conditioner outdoor unit comprises a body assembly, an air outlet assembly, and a lifting assembly. The air outlet assembly is located above the body assembly and is used to exchange gases inside and outside the body assembly. The lifting assembly connects the body assembly and the air outlet assembly. The lifting assembly causes the air outlet assembly to rise and separate or fall and engage relative to the body assembly. Thus, under the action of the lifting assembly, the air outlet assembly and the body assembly are raised and separated or lowered and engaged, so that the air outlet assembly and the interior of the body assembly on which the air outlet assembly is installed have sufficient cleaning operation space for cleaning.

[0004] However, the existing air outlet components of the outdoor air conditioning units include a grille, fan, and fan blades. Because the fan and fan blades are relatively heavy, the overall weight of the air outlet components is also heavy. This excessively increases the energy consumption of the lifting components used to drive the air outlet components to rise and separate or lower and engage relative to the main body components, thus significantly increasing the operating energy consumption of the outdoor air conditioning unit. Furthermore, the air outlet grille, including the grille, is always unobstructed and lacks dust prevention, allowing dust, debris, and dirt to enter the outdoor unit unimpeded, easily causing blockages and affecting heat exchange performance. Summary of the Invention

[0005] To achieve the primary objective of this utility model, this utility model provides an outdoor air conditioning unit that can cover the grille vents to prevent dust, thereby improving the dust prevention effect and reducing the load energy consumption of driving the grille to open, thus reducing the overall operating energy consumption, thereby achieving better dust prevention and easy cleaning, and further improving heat exchange performance.

[0006] To achieve the second objective of this utility model, this utility model provides an air conditioner having the above-mentioned outdoor unit.

[0007] To achieve the first objective of this utility model, this utility model provides an outdoor air conditioning unit, including a casing, an outdoor fan, an outdoor heat exchanger, a grille, a cleaning control mechanism, an air guide plate, and a dust control mechanism. The outdoor fan and the outdoor heat exchanger are respectively installed inside the casing. The panel of the casing has a through hole, and the grille can be closed at the through hole. The cleaning control mechanism can control the entire area or part of the grille to move outward away from the panel. The air guide plate is movably supported on the grille. The dust control mechanism can control the movement of the air guide plate to open or close the grille vent of the grille.

[0008] As can be seen from the above scheme, the outdoor unit of this utility model can open or close the grille vent of the air cover through the air guide plate. When the outdoor unit is in the closed and idle state, the dust control mechanism controls the air guide plate to move to close the grille vent of the air cover, thereby blocking the grille vent to prevent external dust, debris, dirt and other contaminants from entering the casing through the grille vent of the air cover. It also has windproof and rainproof functions. If the outdoor unit detects that the air guide plate and the air cover are clogged and can identify that it is light to moderate rain, it can activate the self-cleaning function. That is, the cleaning control mechanism controls the bottom area of ​​the air cover away from the casing panel to move outward, so that the air cover is tilted downward and outward relative to the casing panel, so that light to moderate rainwater washes the air guide plate and the air cover, while preventing rainwater from splashing into the casing. After the air guide plate and the air cover complete the self-cleaning, the cleaning control mechanism controls the bottom area of ​​the air cover near the casing panel to move inward, so that the air cover closes to the through hole of the panel. Furthermore, when the outdoor unit of the air conditioner is in operation, the dust control mechanism controls the movement of the air guide plate to open the grille vents of the cover. The angle at which the air guide plate opens the grille vents is adjustable, thereby dynamically adjusting the airflow direction to prevent the airflow from blowing directly on people, thus avoiding any impact on their comfort. In addition, when cleaning or maintenance of the internal outdoor fan, outdoor heat exchanger, etc., is required, the cleaning control mechanism can control the entire area or part of the grille to move outwards away from the panel, providing sufficient operating space between the grille and the panel of the casing for cleaning or maintenance of the internal components, making cleaning or maintenance easier. Moreover, compared to existing air conditioner outdoor units where the air outlet components include the grille, fan, and fan blades, resulting in a heavy load, the air guide plate on the grille of this air conditioner outdoor unit is much lighter than the fan and fan blades, thus significantly reducing the energy consumption of driving the grille movement and consequently reducing the overall operating energy consumption of the unit.

[0009] Therefore, the outdoor unit of this air conditioner can cover the grille vents to prevent dust, thereby improving the dust prevention effect and reducing the load energy consumption of driving the grille to open, thus reducing the overall operating energy consumption, thereby achieving better dust prevention and easy cleaning, and further improving heat exchange performance.

[0010] A further option is to provide a limiting annular groove recessed around the perimeter of the through hole on the outer side of the panel, and to provide a limiting annular ridge protruding from the outer periphery of the grille, with the limiting annular ridge located within the limiting annular groove.

[0011] A further solution is that the cleaning control mechanism includes a cleaning motor and a telescopic rod. The drive end of the telescopic rod is connected to the grille, and the mounting end of the telescopic rod is connected to the panel. The cleaning motor is located inside the housing and can control the extension and retraction of the drive end of the telescopic rod, so that the drive end of the telescopic rod can force the entire area or part of the grille to move outward away from the panel.

[0012] A further option is to use two telescopic rods, which are arranged side by side in the vertical direction. When the grid cover is forced to move outward away from the panel, the extension strokes of the two telescopic rods that force the grid cover to move outward away from the panel may be the same or different.

[0013] A further design involves a guide vane comprising multiple plates arranged around the through-hole. Each plate is rotatably hinged to a support rod of the grille cover, and each plate is rotatably hinged to the grille cover. The dust control mechanism can simultaneously or separately control the rotation of multiple plates to open or close the grille vents.

[0014] A further embodiment is that the dust control mechanism includes multiple moving rods and a drive control mechanism. Each moving rod is adapted to a plate. Each moving rod has a drive groove recessed on its outer periphery. Each plate has a transmission plate protruding from it. The transmission plate is located in the drive groove. The moving rods can be moved radially on the grid cover through the through hole. The drive control mechanism can control multiple moving rods to move radially through the through hole simultaneously or separately, so as to force the transmission plate to drive the plate to rotate through the drive groove.

[0015] A further option is that each plate has a locking groove at both ends of the circumferential direction of the through hole. The locking groove has an opening, through which the support rod can be hinged. The locking groove has limit blocks protruding from the groove surfaces at opposite ends of the circumferential direction of the through hole. The two limit blocks can be located on the side of the support rod closer to the opening to restrict the support rod within the locking groove.

[0016] A further embodiment is that the drive control mechanism includes a drive motor, a driving bevel gear, and multiple driven bevel gears. The driving bevel gear is sleeved on the drive shaft of the drive motor, and a driven bevel gear is sleeved on the lead screw section of a moving rod and meshes with the driving bevel gear. The grid cover is provided with multiple positioning grooves, and one positioning groove is sleeved on a driven bevel gear to restrict the driven bevel gear from moving radially in the through hole.

[0017] A further option is to have multiple sets of air guide plates, which are arranged coaxially in the radial direction of the through hole. Each moving rod has multiple drive slots recessed on its outer periphery, which are arranged in the radial direction of the through hole. One plate in one set of air guide plates is adapted to one drive slot in one moving rod.

[0018] To achieve the second objective of this utility model, this utility model provides an air conditioner, including an outdoor unit, which is the aforementioned outdoor unit. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0034] See Figures 1 to 9 This embodiment discloses an outdoor air conditioner unit, including a housing 60, an outdoor fan 50, an outdoor heat exchanger 40, and a grille 20. The outdoor fan 50 and the outdoor heat exchanger 40 are respectively disposed inside the housing 60. A through hole 611 is provided through the panel 61 of the housing 60, and the grille 20 can be closed at the through hole 611. Furthermore, the outdoor air conditioner unit of this embodiment also includes a cleaning control mechanism, an air guide plate 10, and a dust prevention control mechanism. The cleaning control mechanism can control the entire area or part of the grille 20 to move outward away from the panel 61. The air guide plate 10 is movably supported on the grille 20. The dust prevention control mechanism can control the movement of the air guide plate 10 to open or close the grille vent 21 of the grille 20.

[0035] In this embodiment, the outdoor unit of the air conditioner can open or close the grille vent 21 of the grille cover 20 via the air guide plate 10. When the outdoor unit is in a closed, idle state, the dust control mechanism controls the air guide plate 10 to move and close the grille vent 21 of the grille cover 20. Figure 10 As shown, this design effectively blocks dust from the grille vent 21, preventing external dust, debris, and dirt from entering the housing 60 through the grille vent 21 of the grille cover 20. It also provides wind and rain protection. If the outdoor unit detects dirt blockage at the air guide plate 10 and the grille cover 20, and identifies light to moderate rain, it can activate the self-cleaning function. The cleaning control mechanism moves the bottom area of ​​the grille cover 20 away from the panel 61 of the housing 60 outwards, causing the grille cover 20 to tilt downwards and outwards relative to the panel 61 of the housing 60. Figure 13 and Figure 14 As shown, this allows light to moderate rainwater to wash the air guide plate 10 and the grille 20, while preventing rainwater from splashing into the casing 60. After the air guide plate 10 and the grille 20 complete self-cleaning, the cleaning control mechanism controls the bottom area of ​​the grille 20 near the panel 61 of the casing 60 to move inward, so that the grille 20 closes to the through hole 611 of the panel 61. Furthermore, when the outdoor unit of the air conditioner is in operation, the dust control mechanism controls the air guide plate 10 to move and open the grille vent 21 of the grille 20. The angle at which the air guide plate 10 opens the grille vent 21 of the grille 20 is adjustable, thereby dynamically adjusting the airflow direction. Figure 11 and Figure 12As shown, this is to prevent the air outlet 21 from blowing directly onto people, thus avoiding any impact on their comfort. Furthermore, in this embodiment, when the outdoor unit needs cleaning or maintenance of the indoor outdoor fan 50, outdoor heat exchanger 40, etc., the cleaning control mechanism can control the entire area or part of the grille 20 to move outwards away from the panel 61. This provides sufficient operating space between the grille 20 and the panel 61 of the casing 60 for cleaning or maintenance of the components inside the casing 60, making cleaning or maintenance easier. Additionally, compared to existing air conditioner outdoor units where the air outlet assembly includes a grille, fan, and fan blades, resulting in a heavy load, this embodiment uses a guide plate 10 on the grille 20. The guide plate 10 is much lighter than the fan and fan blades, significantly reducing the energy consumption required to move the grille 20, thereby reducing the overall operating energy consumption of the unit.

[0036] Therefore, in this embodiment, the outdoor unit of the air conditioner can cover the grille vent 21 to prevent dust, thereby improving the dust prevention effect and reducing the load energy consumption of driving the grille cover 20 to open, thus reducing the overall operating energy consumption, thereby achieving better dust prevention and easy cleaning, and further improving heat exchange performance.

[0037] In order to improve the accuracy of the cover 20 fitting on the through hole 611, in this embodiment, the outer side of the panel 61 is provided with a limiting annular groove 612 around the periphery of the through hole 611, and the outer periphery of the cover 20 is provided with a limiting annular rim 22, which can be located in the limiting annular groove 612.

[0038] To improve the stability and reliability of the grid cover 20 moving away from or closer to the panel 61, the cleaning control mechanism in this embodiment includes a cleaning motor and a telescopic rod 80. The driving end of the telescopic rod 80 is connected to the grid cover 20, and the mounting end of the telescopic rod 80 is connected to the panel 61. The cleaning motor is installed inside the housing 60 and can control the telescopic rod 80 to extend and retract, so that the driving end of the telescopic rod 80 can force the entire area or part of the grid cover 20 to move away from the panel 61 and outward.

[0039] Specifically, in this embodiment, there are two telescopic rods 80, arranged side by side in a vertical direction. When the grille 20 is forced to move outward away from the panel 61, the extension strokes of the two telescopic rods 80 forcing the grille 20 to move outward away from the panel 61 may be the same or different. Therefore, when the extension strokes of the two telescopic rods 80 forcing the grille 20 to move outward away from the panel 61 are the same, the entire area of ​​the grille 20 moves outward away from the panel 61; when the extension strokes of the two telescopic rods 80 forcing the grille 20 to move outward away from the panel 61 are different, a portion of the grille 20 moves outward away from the panel 61, so that the grille 20 is tilted downward or upward relative to the panel 61 of the housing 60. Figure 13 and Figure 14 The image shows a downward and outward tilt setting.

[0040] Combination Figures 2 to 8 In this embodiment, the air guide plate 10 is formed by multiple plates 102 around the through hole 611. Each plate 102 is rotatably hinged to the support rod 24 of the grille cover 20. The dust control mechanism can control the rotation of multiple plates 102 simultaneously or separately to open or close the grille vent 21, thereby expanding the adjustable range of the angle at which the air guide plate 10 opens the grille vent 21 of the grille cover 20, and thus expanding the adjustable range of the air outlet direction. Specifically, in this embodiment, one air guide plate 10 is formed by four plates 102 around the through hole 611, so that the four plates 102 forming one air guide plate 10 are evenly distributed around the through hole 611, so that the support force of the grille cover 20 is uniform.

[0041] In this embodiment, the dust control mechanism includes multiple moving rods 30 and a drive control mechanism. Each moving rod 30 is adapted to a plate 102. Each moving rod 30 has a drive groove 303 recessed on its outer periphery. Each plate 102 has a transmission plate 102 protruding from it. The transmission plate 102 is located in the drive groove 303. The moving rods 30 can be moved radially on the grid cover 20 through the through hole 611. The drive control mechanism can control multiple moving rods 30 to move radially in the through hole 611 simultaneously or separately, so as to force the transmission plate 102 to drive the plate 102 to rotate through the drive groove 303. Therefore, when the drive control mechanism controls multiple moving rods 30 to move radially in the through hole 611 simultaneously or separately, the drive groove 303 of the moving rod 30 forces the transmission plate 102 of the plate 102 to move radially in the through hole 611. The transmission plate 102 synchronously drives the plate 102 to rotate on the grid cover 20 to open or close the grille vent 21 of the grid cover 20. The drive control works stably and reliably.

[0042] Furthermore, in this embodiment, each plate 102 is provided with a locking groove 103 at both ends of the through hole 611 in the circumferential direction. The locking groove 103 has an opening 104. The support rod 24 of the grid cover 20 can be hinged in the locking groove 103 through the opening 104. The locking groove 103 has a limiting block 105 protruding from the groove surface at both ends of the through hole 611 in the circumferential direction. The two limiting blocks 105 can be located on the side of the support rod 24 near the opening 104 to restrict the support rod 24 in the locking groove 103. This improves the working stability and reliability of the plate 102 being rotatably hinged to the support rod 24 of the grid cover 20, and enhances the ease of operation of the plate 102 being disassembled and installed on the support rod 24 of the grid cover 20.

[0043] To further improve the stability and reliability of the hinged rotation of the plate 102 on the grid cover 20, the drive control mechanism in this embodiment includes a drive motor 90, a driving bevel gear 70, and multiple driven bevel gears 302. The driving bevel gear 70 is sleeved on the drive shaft of the drive motor 90, and one driven bevel gear 302 is sleeved on the lead screw section 301 of a moving rod 30 and meshes with the driving bevel gear 70. The grid cover 20 is provided with multiple positioning grooves 23, and one positioning groove 23 is sleeved on one driven bevel gear 302 to restrict the radial movement of the driven bevel gear 302 in the through hole 611. Thus, as the driving bevel gear 70 drives the driven bevel gear 302 to rotate, since the driven bevel gear 302 is sleeved on the lead screw section 301 of the moving rod 30, and the positioning groove 23 restricts the radial movement of the driven bevel gear 302 in the through hole 611, the moving rod 30 can move radially in the through hole 611 to control the rotation of the plate 102.

[0044] To further expand the adjustable range of the air outlet direction, the number of air guide plates 10 in this embodiment is multiple sets. Multiple sets of air guide plates 10 are arranged coaxially in the radial direction of the through hole 611. Multiple drive grooves 303 are recessed in the outer periphery of each moving rod 30. Multiple drive grooves 303 are arranged in the radial direction of the through hole 611. One plate 102 of one set of air guide plates 10 is adapted to one drive groove 303 of one moving rod 30.

[0045] The above embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles of this utility model patent application should be included within the scope of this utility model patent application.
