Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a window air conditioner and its rear partition. Background Technology

[0002] Typically, a window air conditioner consists of components such as an outer casing, chassis, evaporator (indoor side), condenser (outdoor side), compressor, front partition, rear partition, motor, indoor fan blades, and outdoor fan blades. During operation, the chassis stores condensate. The rotating outdoor fan blades, supported by the guide ring on the rear partition, fling the condensate from the chassis onto the condenser, assisting in heat dissipation and cooling, thereby improving heat exchange efficiency.

[0003] In order to draw in air to cool the compressor, the outer tip of the outdoor fan blades needs to extend beyond the air intake side of the rear baffle's guide ring. This causes some condensate to be flung up by the outer tip of the outdoor fan blades, creating a tangential centrifugal motion that allows it to fly out of the air conditioner through the grille of the outer casing, resulting in condensate splashing. This leads to the following consequences: Firstly, the amount of condensate stored in the chassis is reduced, resulting in decreased cooling efficiency of components such as the compressor and condenser, thus reducing the air conditioner's heat exchange efficiency. Secondly, the splashing of condensate outside the air conditioner can pollute or damage the surrounding environment and objects, thus affecting the user experience.

[0004] To prevent water splashing, one type of window air conditioner has multiple baffles on the air inlet side of the rear partition. These baffles are arranged circumferentially along the airflow guide ring of the rear partition, and each baffle has a through-hole for atomizing air, which then enters the condenser mounting position. To further prevent water splashing, another type of window air conditioner has multiple baffles on the air inlet side of the rear partition, arranged circumferentially along the airflow guide ring of the rear partition. Adjacent baffles partially overlap, but the overlapping parts are not tightly connected, resulting in misaligned gaps.

[0005] However, the multiple baffles arranged circumferentially along the air guide ring of the rear partition in the aforementioned existing window air conditioners obstruct the airflow around the air guide ring, resulting in a reduction in airflow volume and thus affecting the heat dissipation and cooling effect as well as the overall heat exchange efficiency. Furthermore, the aforementioned existing window air conditioners have partial overlap between adjacent baffles arranged circumferentially along the air guide ring of the rear partition, further obstructing the airflow and further reducing the airflow volume, further impacting the heat dissipation and cooling effect as well as the overall heat exchange efficiency. Utility Model Content

[0006] To achieve the primary objective of this utility model, a rear partition for a window air conditioner is provided, which can effectively block water splashes without significantly increasing wind resistance, thereby increasing the intake air volume and making full use of condensate to improve heat dissipation and cooling effect, thus improving the overall heat exchange efficiency of the unit.

[0007] To achieve the second objective of this utility model, this utility model provides a window air conditioner having the aforementioned rear partition.

[0008] To achieve the first objective of this utility model, this utility model provides a rear partition of a window air conditioner, through which a guide ring is provided. A fan blade mounting position is provided within the guide ring for installing an outdoor fan blade. The air inlet side of the rear partition is used to install a compressor, and the air outlet side of the rear partition is used to install a condenser. An anti-splashing structure is provided on the air inlet side of the rear partition. The anti-splashing structure is located on the left side of the guide ring when the outdoor fan blade is rotated clockwise and viewed directly. The anti-splashing structure includes multiple first baffles. The multiple first baffles protrude from the air inlet side of the rear partition and are arranged side by side in the vertical direction. The first blocking end of the first baffle is located close to the guide ring, and the first guiding end of the first baffle is located away from the guide ring. Each first baffle extends from the first blocking end to the first guiding end at an angle from top to bottom.

[0009] As can be seen from the above scheme, during the rotation of the outdoor fan blades of this utility model window air conditioner to fling up the condensate in the chassis and direct it to the condenser for heat dissipation and cooling, it can be seen from the clockwise rotation of the outdoor fan blades that the outer tips of the outdoor fan blades will fling up some of the condensate and radiate it mainly to the left along the tangential centrifugal motion of the clockwise rotation direction of the outdoor fan blades. Therefore, the water splashing is basically concentrated on the left side of the guide ring in the clockwise rotation direction of the outdoor fan blades. Since the outer casing has a left air intake grille that is connected to the air intake cavity through the left side wall of the outdoor fan blades in the clockwise rotation direction of the outdoor fan blades, water splashing occurs on the left air intake grille. Therefore, this utility model window air conditioner has a water splash prevention structure on the air intake side of the rear partition. This water splash prevention structure is located on the left side of the guide ring in the clockwise rotation direction of the outdoor fan blades, and the water splash prevention structure includes multiple first baffles, which protrude from the air intake side of the rear partition. The first baffle plates are arranged side-by-side vertically, with the first blocking end of the first baffle plate positioned close to the guide ring and the first guiding end positioned away from the guide ring. This effectively blocks the condensate water radiating from the outer tips of the outdoor fan blades towards the left. Furthermore, each first baffle plate extends downwards from its first blocking end to its first guiding end, thus directing the condensate water blocked by the first blocking end of the first baffle plate to the first guiding end of the first baffle plate below, allowing the condensate water to drip back into the chassis for recycling. In addition, the first guiding end of the first baffle plate near the left air intake grille is located below the first blocking end of the first baffle plate near the guide ring, so that the tilt direction of the first baffle plate is basically in line with the clockwise rotation direction of the outdoor fan blades. Therefore, the first baffle plate does not significantly increase the wind resistance of the air intake grille on the left side, and even plays a guiding role in the air intake, thereby increasing the air volume of the air intake grille on the left side.

[0010] Therefore, the rear partition of the window air conditioner of this utility model is provided with a water-prevention structure on the left side of the air guide ring when the outdoor fan blade is rotated clockwise. The water-prevention structure includes multiple first water baffles arranged side by side in the vertical direction. Each first water baffle extends from the first blocking end to the first air guide end from top to bottom, so that the first water baffle has the functions of blocking water, diverting water, dripping water and guiding air. It can effectively block water splashing without significantly increasing wind resistance, thereby increasing the air intake volume and making full use of condensate to improve the heat dissipation and cooling effect, thereby improving the overall heat exchange efficiency of the unit.

[0011] A further option is to have a first water-blocking protrusion protruding downwards at the first guide end.

[0012] A further embodiment is that the anti-splash structure also includes at least one second baffle plate, with a spacing between two adjacent first baffle plates. The second baffle plate protrudes from the air inlet side of the rear partition and is located in the lowest spacing. The second blocking end of the second baffle plate is located close to the guide ring, and the second guiding end of the second baffle plate is located away from the guide ring. Each second baffle plate extends from the second blocking end to the second guiding end at an angle from top to bottom.

[0013] A further option is to have a second water-blocking protrusion protruding downwards at the second guide end; and / or, to have the first blocking end protruding towards the guide ring and the second blocking end protruding from the first guide end away from the guide ring.

[0014] A further option is that the first angle of inclination between the first baffle plate and the horizontal direction is smaller than the second angle of inclination between the second baffle plate and the horizontal direction.

[0016] A further design is that the first height of the first baffle protruding from the air inlet side of the rear partition is greater than the second height of the second baffle protruding from the air inlet side of the rear partition.

[0017] A further option is to have at least two second baffles, with multiple second baffles arranged side by side in the vertical direction on the lower side of the rear partition, and one second baffle located in a spacing between the arrangement on the lower side of the rear partition.

[0018] A further embodiment is that the anti-splash structure also includes at least one third baffle plate. The third baffle plate protrudes from the air inlet side of the rear partition and is located in the upper arrangement gap adjacent to the uppermost second baffle plate. The third blocking end of the third baffle plate is located close to the guide ring, and the third guiding end of the third baffle plate is located away from the guide ring. Each third baffle plate extends from the third blocking end to the third guiding end at an angle from top to bottom. The first blocking end protrudes from the third blocking end toward the guide ring, and the first guiding end protrudes from the third guiding end away from the guide ring.

[0019] A further embodiment is that the first height of the first baffle protruding from the air inlet side of the rear partition is greater than the third height of the third baffle protruding from the air inlet side of the rear partition; and / or, the third guide end is provided with a third baffle protrusion protruding downwards; and / or, the third baffle is arranged parallel to the second baffle.

[0020] A further option is that the first height of the first baffle protruding from the air inlet side of the rear partition is greater than the outward extension height of the outer peripheral blade tip of the outdoor fan blade protruding from the air inlet side of the rear partition; and / or, multiple first baffles are arranged side by side at equal intervals in the vertical direction.

[0021] A further design includes a deflector plate on the air inlet side of the protruding rear partition. The deflector plate consists of a connected arc-shaped section and an inclined section. The inclined section is located below the first water baffle, and the outlet end of the inclined section away from the arc-shaped section extends downwards away from the first water baffle. The receiving end of the arc-shaped section away from the inclined section bends upwards, and the receiving end protrudes towards the guide ring to form a fourth water baffle protrusion. The fourth water baffle protrusion is located on the left side of the second guide end away from the guide ring when the outdoor fan blades are rotated clockwise.

[0022] A further proposed solution is that the fourth height of the diverter plate protruding from the air inlet side of the rear partition is greater than the first height of the first baffle plate protruding from the air inlet side of the rear partition.

[0023] To achieve the second objective of this utility model, this utility model provides a window air conditioner, including a rear partition, which is the rear partition of the aforementioned window air conditioner.

[0024] A further embodiment is that the window air conditioner includes an outer casing, a chassis, an outdoor fan blade, a compressor, and a condenser. The outer casing covers the chassis and forms a receiving cavity with the chassis. The rear partition is located in the receiving cavity and divides the receiving cavity into an air inlet cavity and an air outlet cavity. The outdoor fan blade is installed in the fan blade mounting position within the air guide ring of the rear partition. The compressor is located on the air inlet side of the rear partition and is located in the air inlet cavity. The condenser is located on the air outlet side of the rear partition and is located in the air outlet cavity. The condenser is U-shaped, and the outdoor fan blade is inserted into the U-shaped cavity of the condenser. The outer casing has a left-side air inlet grille that is connected to the air inlet cavity, which is opened through the left side wall of the outdoor fan blade when rotated clockwise; the outer casing has a left-side air outlet grille that is connected to the air outlet cavity, which is opened through the left side wall of the outdoor fan blade when rotated clockwise, and the left-side air outlet grille is correspondingly arranged to the first side wall of the U-shaped condenser; and / or, the outer casing has a right-side air outlet grille that is connected to the air outlet cavity, which is opened through the right side wall of the outdoor fan blade when rotated clockwise, and the right-side air outlet grille is correspondingly arranged to the second side wall of the U-shaped condenser.

The top air intake grille includes multiple air inlets arranged side by side in the left-right direction of the outer casing. Each air inlet has a fourth baffle plate protruding downwards to the left of the outdoor fan blade when rotated clockwise. The fourth baffle plate includes a first plate segment and a second plate segment connected to each other. The first plate segment is connected to the left side of the air inlet and extends downwards at an angle from the left side of the air inlet toward the right side of the air inlet. The second plate segment is located below the first plate segment, and the angle between the first plate segment and the second plate segment is less than 35°. Attached Figure Description

[0043] See Figures 1 to 10In this embodiment, the window air conditioner 10 includes an outer casing 11, a chassis 12, an outdoor fan blade 16, a compressor 14, a condenser 15, a rear partition 17, an evaporator 13, a front partition 19, a motor 18, and an indoor fan blade 110. The outer casing 11 covers the chassis 12 and forms a receiving cavity with the chassis 12. The rear partition 17 is located in the receiving cavity and divides the receiving cavity into an air inlet cavity and an air outlet cavity. The front partition 19 is located in the receiving cavity and forms an indoor cavity with the outer casing 11 and the chassis 12. The indoor fan blade 110 and the evaporator 13 are respectively located in the indoor cavity, wherein the air inlet cavity is located between the front partition 19 and the rear partition 16. Between the partitions 17, the motor 18 and the compressor 14 are located on the air inlet side of the rear partition 17 and are located in the air inlet cavity, and the condenser 15 is located on the air outlet side of the rear partition 17 and is located in the air outlet cavity. The outdoor fan blade 16 is installed in the fan blade mounting position in the guide ring 171 of the rear partition 17. The indoor fan blade 110 is supported on the front partition 19. The motor 18 controls the rotation of the indoor fan blade 110 and the outdoor fan blade 16 respectively. The chassis 12 is used to store condensate. The outer cover 11 has a left air inlet grille 112 that is connected to the air inlet cavity through the left side wall of the outdoor fan blade 16 when it is rotated clockwise.

[0044] In this embodiment, the rear partition 17 of the window air conditioner 10 is provided with a guide ring 171, and a fan blade mounting position is provided inside the guide ring 171. The fan blade mounting position is used to install the outdoor fan blade 16. The air inlet side of the rear partition 17 is used to install the compressor 14, and the air outlet side of the rear partition 17 is used to install the condenser 15.

[0045] Meanwhile, in this embodiment, the air inlet side of the rear partition 17 is provided with a water-proof structure, which is located on the left side of the guide ring 171 when the outdoor fan blade 16 is rotated clockwise and viewed directly. The left and right sides of the guide ring 171 when the outdoor fan blade 16 is rotated clockwise and viewed directly are consistent with the left and right sides of the window air conditioner 10 when viewed from the front of the panel.

[0046] Furthermore, the anti-splash structure of this embodiment includes multiple first water baffles 172. The multiple first water baffles 172 are arranged protruding from the air inlet side of the rear partition 17 and are arranged side by side in the vertical direction. The first blocking end 1721 of the first water baffle 172 is arranged close to the guide ring 171, and the first guide end 1722 of the first water baffle 172 is arranged away from the guide ring 171. Each first water baffle 172 extends from the first blocking end 1721 to the first guide end 1722 at an angle from top to bottom, and the first guide end 1722 is provided with a first water-blocking protrusion 1723 protruding downward.

[0047] See Figure 11As shown, in this embodiment, during the rotation of the outdoor fan blade 16 of the window air conditioner 10 to throw up the condensate in the chassis 12 and send it to the condenser 15 for heat dissipation and cooling, it can be seen from the clockwise rotation of the outdoor fan blade 16 that the outer tip of the outdoor fan blade 16 will throw up some of the condensate and radiate it mainly to the left along the tangential centrifugal motion of the outdoor fan blade 16 in the clockwise rotation direction. Therefore, the condensate is basically concentrated on the left side of the guide ring 171 in the clockwise rotation direction of the outdoor fan blade 16. Figure 7 and Figure 11 As shown on the left side, because the outer casing 11 has a left air intake grille 112 that is connected to the air intake cavity through the left side wall of the outdoor fan blade 16 when viewed clockwise, water splashing can occur at the left air intake grille 112. Therefore, in this embodiment, the window air conditioner 10 is provided with a water splash prevention structure on the air intake side of the rear partition 17. This water splash prevention structure is located to the left of the guide ring 171 when viewed clockwise from the outdoor fan blade 16, and the water splash prevention structure includes multiple first water baffles 172, which protrude from the air intake side of the rear partition 17. The first baffle plates 172 are arranged side-by-side in a vertical direction. The first blocking end 1721 of the first baffle plate 172 is positioned close to the guide ring 171, while the first guide end 1722 of the first baffle plate 172 is positioned away from the guide ring 171. This allows them to block the condensate water radiated from the outer blade tip of the outdoor fan blade 16 as it is thrown to the left. Furthermore, each first baffle plate 172 extends from the first blocking end 1721 to the first guide end 1722 at an angle from top to bottom, thereby guiding the condensate water blocked by the first blocking end 1721 of the first baffle plate 172 to the first guide end 1722 below. The first guide end 1722 of the baffle plate 172 has a first water-blocking protrusion 1723 protruding downwards. This first water-blocking protrusion 1723 can block the condensate flowing to the first guide end 1722 of the baffle plate 172, preventing the condensate from flying out of the left air inlet grille 112. Furthermore, the downward-protruding first water-blocking protrusion 1723 can also divert the condensate flowing to the first guide end 1722 of the baffle plate 172 downwards. The condensate drips back into the chassis 12 for recycling. In addition, the first guide end 1722 of the first baffle plate 172 near the left air intake grille 112 is located below the first blocking end 1721 of the first baffle plate 172 near the guide ring 171, so that the tilt direction of the first baffle plate 172 is basically in line with the clockwise rotation direction of the outdoor fan blade 16. Thus, the first baffle plate 172 will not significantly increase the wind resistance of the air intake of the left air intake grille 112, and even plays a role in guiding the air intake, thereby increasing the air intake volume of the left air intake grille 112.

[0048] Therefore, in this embodiment, the rear partition 17 of the window air conditioner 10 is provided with a water-preventing structure on the left side of the air guide ring 171 when the outdoor fan blade 16 is rotated clockwise. The water-preventing structure includes a plurality of first water baffles 172 arranged side by side in the vertical direction. Each first water baffle 172 extends from the first blocking end 1721 to the first air guide end 1722 from top to bottom at an angle. The first air guide end 1722 is provided with a first water-preventing protrusion 1723 protruding downwards. This allows the first water baffle 172 to have the functions of blocking water, guiding water, dripping water, and guiding air. It can effectively block water splashing without significantly increasing wind resistance, thereby increasing the air intake volume and making full use of condensate to improve the heat dissipation and cooling effect, thereby improving the overall heat exchange efficiency of the unit.

[0049] To ensure sufficient height to block splashing water, in this embodiment, the first height H1 of the first baffle plate 172 protruding from the air inlet side of the rear partition 17 is greater than the outward extension height H3 of the outer peripheral blade tip of the outdoor fan blade 16 protruding from the air inlet side of the rear partition 17. Preferably, in this embodiment, the first height H1 is at least 2 mm greater than the outward extension height H3. Optionally, in this embodiment, multiple first baffle plates 172 are arranged side by side at equal intervals in the vertical direction.

[0050] The water splashing is mainly concentrated on the left side of the guide ring 171 when viewed clockwise from the outside fan blade 16. When the outer blade tip of the outside fan blade 16 rotates clockwise and just kicks up the condensate in the chassis 12 to the left, the amount of water splashing on the lower left side of the guide ring 171 when viewed clockwise from the outside fan blade 16 is relatively greater than that on the upper left side. Therefore, the excessive amount of water splashing on the lower left side of the guide ring 171 when viewed clockwise from the outside fan blade 16 may pose a potential water splashing hazard.

[0051] To address the potential water splashing hazard on the lower left side of the guide ring 171, this embodiment's anti-water splashing structure further includes at least one second baffle plate 173. A spacing 1724 exists between adjacent first baffle plates 172. The second baffle plate 173 protrudes from the air inlet side of the rear partition 17 and is located within the lowest spacing 1724. Simultaneously, the second blocking end 1731 of the second baffle plate 173 is positioned close to the guide ring 171, while the second guiding end 1732 of the second baffle plate 173 is positioned away from the guide ring 171. Each second baffle plate 173 extends downwards from the second blocking end 1731 to the second guiding end 1732, with a second water-blocking protrusion 1733 protruding downwards from the second guiding end 1732. Furthermore, the first blocking end 1721 protrudes from the second blocking end 1731 towards the guide ring 171, while the second guiding end 1732 protrudes from the first guiding end 1722 away from the guide ring 171.

[0052] Therefore, the anti-splashing structure of this embodiment also includes at least one second baffle plate 173. The second baffle plate 173 is located within the arrangement gap 1724 between two adjacent first baffle plates 172 at the bottom left. The second blocking end 1731 of the second baffle plate 173 is recessed from the guide ring 171 relative to the first blocking end 1721 of the first baffle plate 172, thereby effectively blocking the splashing water within the arrangement gap 1724, and thus effectively blocking a large amount of splashing water from the lower left. Extending downwards from the second blocking end 1731 to the second guide end 1732, the condensate blocked by the second blocking end 1731 of the second baffle plate 173 is directed to the second guide end 1732 of the lower second baffle plate 173. Simultaneously, a second water-blocking protrusion 1733 protrudes downwards from the second guide end 1732, which blocks the condensate flowing to the second guide end 1732 of the second baffle plate 173, preventing the condensate from flowing to the second guide end 1732 of the second baffle plate 173. The condensate on the flow end 1732 flies out of the left air intake grille 112. Because the second guide end 1732 of the second baffle plate 173 protrudes from the first guide end 1722 of the first baffle plate 172, away from the guide ring 171, the downward-protruding second baffle protrusion 1733 directly guides the condensate flowing to the second guide end 1732 of the second baffle plate 173 downwards, allowing the condensate to drip directly back into the chassis 12 for recycling. Furthermore, the second baffle plate 173 is close to the left air intake grille 112. The second guide end 1732 of 12 is located below the second blocking end 1731 of the second baffle plate 173 near the guide ring 171, so that the tilt direction of the second baffle plate 173 deviates less from the clockwise rotation air intake direction of the outdoor fan blade 16. Thus, the second baffle plate 173 will not significantly increase the wind resistance of the air intake below the left air intake grille 112, and even plays a certain role in air intake guidance. This solves the problem of water splashing on the lower left side of the guide ring 171 while ensuring the air intake volume of the left air intake grille 112.

[0053] To avoid excessive air intake resistance, in this embodiment, the first tilt angle θ1 between the first baffle plate 172 and the horizontal direction is smaller than the second tilt angle θ2 between the second baffle plate 173 and the horizontal direction. Specifically, in this embodiment, both the first tilt angle θ1 and the second tilt angle θ2 are between 2° and 40°. The angle θ3 between the second baffle plate 173 and the first baffle plate 172 below it is less than 30°. The spacing height of the arrangement gap 1724 between the two adjacent first baffle plates 172 at the bottom is more than 8 mm. Thus, while ensuring the water blocking effect, the larger the spacing height of the arrangement gap 1724 between the two adjacent first baffle plates 172 at the bottom and the smaller the angle θ3 between the second baffle plate 173 and the first baffle plate 172 below it, the smaller the impact on the air intake resistance. Preferably, in this embodiment, the second inclination angle θ2 between the second baffle plate 173 and the horizontal direction is 30°, the angle θ3 between the second baffle plate 173 and the first baffle plate 172 below it is 15°, and the spacing height of the arrangement gap 1724 between the two adjacent first baffle plates 172 at the bottom is 14 mm.

[0054] To further avoid excessive air intake resistance, in this embodiment, the first height H1 of the first baffle plate 172 protruding from the air intake side of the rear partition 17 is greater than the second height H2 of the second baffle plate 173 protruding from the air intake side of the rear partition 17. This reduces the area of ​​the second baffle plate 173 to reduce air intake resistance while ensuring the water-blocking effect.

[0055] To further address the potential water splashing issue on the lower left side of the guide ring 171, this embodiment uses at least two second baffle plates 173. Multiple second baffle plates 173 are arranged side-by-side in the vertical direction on the lower side of the rear partition 17, with one second baffle plate 173 located within a spacing 1724 on the lower side of the rear partition 17.

[0056] To further enhance the effect of blocking splashing water, the anti-splashing water structure in this embodiment also includes at least one third water baffle 174. The third water baffle 174 protrudes from the air inlet side of the rear partition 17 and is located in the arrangement gap 1724 adjacent to the second water baffle 173. The third blocking end 1741 of the third water baffle 174 is located close to the guide ring 171, and the third guide end 1742 of the third water baffle 174 is located away from the guide ring 171. Each third water baffle 174 extends from the third blocking end 1741 to the third guide end 1742 at an angle from top to bottom. The first blocking end 1721 protrudes from the third blocking end 1741 toward the guide ring 171, and the first guide end 1722 protrudes from the third guide end 1742 away from the guide ring 171. Therefore, in this embodiment, the third baffle plate 174 is located above the second baffle plate 173 and within the middle arrangement gap 1724 of the left air inlet grille 112. The third blocking end 1741 of the third baffle plate 174 is recessed relative to the first blocking end 1721 of the first baffle plate 172, away from the guide ring 171, thereby effectively blocking the splashing water in the middle arrangement gap 1724. Furthermore, the third baffle plate 174 extends downwards from the third blocking end 1741 to the third guide end 1742, thereby guiding the condensate blocked by the third blocking end 1741 of the third baffle plate 174 to the third guide end 1742 of the lower third baffle plate 174. Since the amount of splashing water in the middle arrangement gap 1724 is much less than that in the lower arrangement gap 1724, the condensate at the third guide end 1742 of the third baffle plate 174 will not actually splash out of the middle of the left air inlet grille 112. The third guide end 1742 of the third baffle plate 174 is recessed relative to the first guide end 1722 of the first baffle plate 172, so that the condensate of the third guide end 1742 of the third baffle plate 174 drips onto the first baffle plate 172 below under the action of gravity and finally drips back into the chassis 12 for recycling. In addition, the third guide end 1742 of the third baffle plate 174 near the left air intake grille 112 is located below the third blocking end 1741 of the third baffle plate 174 near the guide ring 171, so that the tilt direction of the third baffle plate 174 deviates less from the clockwise rotation air intake direction of the outdoor fan blade 16. Thus, the third baffle plate 174 does not significantly increase the wind resistance of the air intake in the middle of the left air intake grille 112, and even plays a certain role in guiding the air intake. This solves the problem of water splashing in the middle of the left side of the guide ring 171 while ensuring the air intake volume of the left air intake grille 112. For safety reasons, in this embodiment, the third guide end 1742 of the third baffle plate 174 can be provided with a third baffle protrusion protruding downwards.

[0057] To further avoid excessive air intake resistance, in this embodiment, the first height H1 of the first baffle plate 172 protruding from the air intake side of the rear partition 17 is greater than the third height of the third baffle plate 174 protruding from the air intake side of the rear partition 17. This reduces the area of ​​the third baffle plate 174 to decrease air intake resistance while maintaining its water-blocking function. Specifically, the third height of the third baffle plate 174 protruding from the air intake side of the rear partition 17 is the same as the second height H2 of the second baffle plate 173 protruding from the air intake side of the rear partition 17, and the third baffle plate 174 is arranged parallel to the second baffle plate 173.

[0058] Furthermore, the anti-splash structure in this embodiment also includes a diverter plate 175 protruding from the air inlet side of the rear partition 17. The diverter plate 175 includes an arc-shaped section 1751 and an inclined section 1752 connected to each other. The inclined section 1752 is located below the lowermost first baffle plate 172, and the inclined section 1752 extends downwards away from the outflow end 17521 of the arc-shaped section 1751 and away from the first baffle plate 172. The arc-shaped section 1751 bends upwards away from the receiving end 17511 of the inclined section 1752. The curved extension extends, with the receiving end 17511 protruding towards the guide ring 171, where a fourth water-blocking protrusion 1753 protrudes. This fourth water-blocking protrusion 1753 is located on the left side of the second guide end 1732, away from the guide ring 171. This ensures that the receiving end 17511 of the arc-shaped segment 1751 of the guide plate 175 in this embodiment is located to the left of the first water-blocking plate 172, the second water-blocking plate 173, and the third water-blocking plate 174. Consequently, the first guide end 1722 of the upper first water-blocking plate 172 and the second water-blocking plate 173... The condensate dripping from the second guide end 1732 and the third guide end 1742 of the third baffle plate 174 is first supported by the arc-shaped section 1751 of the lower guide plate 175. Because the arc-shaped section 1751 of the guide plate 175 is curved, the curved wall of the arc-shaped section 1751 can quickly and smoothly guide the supported condensate to the inclined section 1752 of the lower guide plate 175. Furthermore, the dripping noise generated by the condensate dripping onto the curved section 1751 is relatively small, thus avoiding… To avoid generating significant dripping noise, the inclined section 1752 of the deflector plate 175 quickly guides the condensate into the chassis 12 for recycling, thereby preventing the condensate from dripping directly into the chassis 12 from a higher position and causing splashing and discontinuous noise. In addition, the receiving end 17511 of the arc-shaped section 1751 protrudes towards the guide ring 171 with a fourth water-blocking protrusion 1753, which can prevent the condensate in the arc-shaped section 1751 from flying out towards the left air intake grille 112.

[0059] In order to increase the water receiving and supporting area of ​​the diversion plate 175, in this embodiment, the fourth height H4 of the diversion plate 175 protruding from the air inlet side of the rear partition 17 is greater than the first height H1 of the first baffle plate 172 protruding from the air inlet side of the rear partition 17.

[0060] Specifically, in this embodiment, the condenser 15 is U-shaped, and the outdoor fan blade 16 is inserted into the U-shaped cavity of the condenser 15. Furthermore, in this embodiment, the outer casing 11 has a left-side air outlet grille 114 that communicates with the air outlet cavity on the left side wall of the outdoor fan blade 16 when rotated clockwise. The left-side air outlet grille 114 corresponds to the first side wall 151 of the U-shaped condenser 15. Also in this embodiment, the outer casing 11 has a right-side air outlet grille 114 that communicates with the air outlet cavity on the right side wall of the outdoor fan blade 16 when rotated clockwise. The air grille 115 is arranged on the right side and is correspondingly arranged to the second side wall 152 of the U-shaped condenser 15. This allows the first side wall 151 of the U-shaped condenser 15 to block condensate water, thus preventing water splashing from the left air grille 114, which is correspondingly arranged to the first side wall 151 of the U-shaped condenser 15. Furthermore, the second side wall 152 of the U-shaped condenser 15 can block condensate water, thus preventing water splashing from the right air grille 115, which is correspondingly arranged to the second side wall 152 of the U-shaped condenser 15.

[0061] In order to further increase the air intake, the upper end of the outer cover 11 in this embodiment is provided with a top air intake grille 111 that communicates with the air intake cavity. The top air intake grille 111 includes multiple air inlets 1111, which are arranged side by side in the left and right directions of the outer cover 11. Because the outer tip of the outdoor fan blade 16 will fling up some condensed water and cause it to move tangentially and centrifugally along the clockwise rotation direction of the outdoor fan blade 16, a small amount of water will be splashed above the guide ring 171 in the clockwise rotation direction of the outdoor fan blade 16. Therefore, in this embodiment, each air inlet 1111 has a fourth baffle plate 1112 protruding downwards on the left side of the outdoor fan blade 16 in the clockwise rotation direction. The fourth baffle plate 1112 includes a first plate segment 11121 and a second plate segment 11122 connected to each other. The first plate segment 11121 is connected to the left side of the air inlet 1111, and the first plate segment 11121 extends downwards from the left side of the air inlet 1111 towards the right side of the air inlet 1111. The second plate segment 11122 is located on the first plate segment 1112. Below 1, and the second plate segment 11122 extends downward from the first plate segment 11121 toward the right side of the air inlet 1111, so that the first plate segment 11121 of the fourth baffle plate 1112 in this embodiment can block splashing water and guide the condensate to the second plate segment 11122 of the fourth baffle plate 1112 below, and then drip back into the chassis 12 for recycling. Furthermore, the downward tilting direction of the first plate segment 11121 and the second plate segment 11122 of the fourth baffle plate 1112 is basically in line with the clockwise rotation direction of the outdoor fan blade 16, so that the fourth baffle plate 1112 will not significantly increase the wind resistance of the top air inlet grille 111, and even plays an air intake guiding role, thereby increasing the air intake volume of the top air inlet grille 111.

[0062] To improve the water-blocking and air-guiding effects, in this embodiment, the first plate segment 11121 and the first downward tilt angle β1 in the horizontal direction are acute angles, and the second plate segment 11122 and the second downward tilt angle β2 in the horizontal direction are acute angles, and the second downward tilt angle β2 is greater than the first downward tilt angle β1. Preferably, in this embodiment, the angle β3 between the first plate segment 11121 and the second plate segment 11122 is less than 35°.

[0063] To further increase the air intake volume, in this embodiment, the outer cover 11 has a right-side air intake grille 113 that is connected to the air intake cavity and extends through the right side wall of the outdoor fan blade 16 when viewed clockwise. Since there is no water splashing on the right side of the guide ring 171 when viewed clockwise from the outdoor fan blade 16, there is no need to set a water-blocking structure on the right side of the guide ring 171 when viewed clockwise from the outdoor fan blade 16, thus ensuring the air intake volume of the right-side air intake grille 113.

[0064] 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.
