[0039] In the description of the present utility model, the meaning of "a plurality" is two or more, and the meaning of "several" is one or more.

[0040] Next, refer to the attached Figures 1 - 11 Describe the outdoor unit of an air conditioner according to an embodiment of the present utility model.

[0041] As Figures 1 - 4 shown, the outdoor unit of an air conditioner according to an embodiment of the present utility model includes a housing, an outdoor heat exchanger, an outdoor fan assembly, a compressor, an electric control box, and a waterproof cover 20.

[0042] The housing is arranged in the outdoor environment, allowing outdoor air to enter the housing, facilitating heat exchange between the outdoor air and the outdoor heat exchanger. The housing is provided with an air inlet and an air outlet. The outdoor heat exchanger is disposed inside the housing, and the outdoor fan assembly is disposed inside the housing and on one side of the outdoor heat exchanger. The outdoor fan assembly drives the outdoor air to enter the housing from the air inlet, and after the outdoor air exchanges heat with the outdoor heat exchanger to form a heat exchange air flow, it is driven by the outdoor fan assembly to flow out of the housing from the air outlet.

[0043] In this way, the outdoor unit of the air conditioner can selectively control the outdoor air to enter the housing through the air inlet, and the outdoor air can exchange heat with the outdoor heat exchanger to form a heat exchange air flow, and then be driven by the fan assembly to flow out of the housing from the air outlet, thereby achieving cooling or heating for the interior.

[0044] The compressor is disposed inside the casing, and the compressor is in communication with the outdoor heat exchanger, so that the refrigerant can form a loop between the compressor and the outdoor heat exchanger, enabling the refrigerant to circulate and exchange heat normally in the outdoor unit of the air conditioner.

[0045] The electric control box is disposed inside the casing, and the casing can protect the electric control box to prevent outdoor dust and rain from entering the electric control box. Thus, the working safety of the electric control box can be ensured.

[0046] According to an embodiment of the present invention, a blower cavity and a compressor cavity are formed inside the casing. Among them, the outdoor blower assembly is disposed in the blower cavity so that the outdoor blower assembly operates in the blower cavity to generate negative pressure, which can suck outdoor air into the blower cavity and exchange heat with the outdoor heat exchanger.

[0047] Both the compressor and the electric control box are disposed in the compressor cavity. A partition 10 is provided between the blower cavity and the compressor cavity. The partition 10 can separate the blower cavity and the compressor cavity, so that the compressor and the electric control box are separated from the components in the blower cavity, which can protect the compressor and the electric control box.

[0048] Further, a first ventilation opening 11 is formed on the partition 10, so that the air between the compressor cavity and the blower cavity can be connected. When the outdoor blower assembly works in the blower cavity and generates negative pressure, the air in the compressor cavity can form an air flow and be sucked into the blower cavity through the first ventilation opening 11. In this way, the heat generated by the electric control box in the compressor cavity can follow the air and enter the blower cavity through the first ventilation opening 11, so as to dissipate heat from the electric control box and ensure the working reliability of the electric control box.

[0049] It can be understood that when the outdoor unit of the air conditioner is in the rain, rainwater can enter the inside of the casing through the air inlet and the air outlet. The partition 10 is provided to separate the compressor and the electric control box, which can not only ensure the operation reliability of the compressor, but also prevent rainwater from appearing on the control board body of the electric control box, thus being beneficial to protecting the safety of the electric control box.

[0050] Combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown in, in an embodiment of the present invention, a waterproof cover 20 is disposed in the blower cavity. The waterproof cover 20 includes a first cover body 21 and a second cover body 22.

[0051] Among them, the first cover body 21 is connected to the partition 10, so that the waterproof cover 20 can be installed on the partition 10, ensuring the structural stability of the waterproof cover 20 in the outdoor unit of the air conditioner.

[0052] Further, a wind guiding channel 211 is formed inside the first cover body 21. The wind guiding channel 211 can define the flow path of the air flow inside the first cover body 21. The wind guiding channel 211 is communicated with the first ventilation opening 11 on the partition plate 10. With such a setting, the air flow in the compressor chamber can enter the first cover body 21 through the first ventilation opening 11 and flow along the wind guiding channel 211.

[0053] Still further, a second ventilation opening 212 is provided on the lower side of the first cover body 21, and the second ventilation opening 212 is communicated with the wind guiding channel 211. In this way, the air flow in the wind guiding channel 211 can flow towards the second ventilation opening 212 and flow out from the second ventilation opening 212. A grille 216 is provided inside the second ventilation opening 212. In this way, it can not only prevent rainwater from entering the wind guiding channel 211 through the second ventilation opening 212, improve the waterproof effect of the wind guiding channel 211, but also block flying insects and dust particles in the fan chamber from entering the wind guiding channel 211 through the second ventilation opening 212, so that the waterproof cover 20 has an insect-proof function while ensuring ventilation.

[0054] The second cover body 22 is arranged on the lower side of the first cover body 21. In this way, the second cover body 22 can be arranged to avoid the first ventilation opening 11, so that the waterproof cover 20 can block the water in the fan chamber from entering the compressor chamber through the first ventilation opening 11. A ventilation channel 221 is formed inside the second cover body 22, and the ventilation channel 221 is communicated with the second ventilation opening 212. In this way, the air flow in the wind guiding channel 211 can flow into the ventilation channel 221 through the second ventilation opening 212.

[0055] Further, the second cover body 22 is arranged at an interval from the partition plate 10. In this way, the ventilation channel 221 can be communicated with the fan chamber, so that the air in the ventilation channel 221 can enter the fan chamber.

[0056] Thus, in the embodiment of the present utility model, the waterproof cover 20 is designed into two parts. Among them, the wind guiding channel 211 of the first cover body 21 is communicated with the compressor chamber so that the air flow in the compressor chamber can enter the waterproof cover 20. The other part is the second cover body 22 which is communicated with both the wind guiding channel 211 and the fan chamber. The second cover body 22 can be arranged to avoid the first ventilation opening 11 and enable the air flow in the compressor chamber to smoothly enter the fan chamber. In this way, it can not only ensure the normal heat dissipation of the electric control box, but also effectively prevent the rainwater in the fan chamber from entering the compressor chamber to ensure the safety of the electric control box.

[0057] Compared with the prior art, the waterproof cover in the embodiment of the present utility model is only arranged on one side of the partition plate, and the material of the waterproof cover includes but is not limited to metal and plastic, thereby reducing the cost of the air conditioner outdoor unit.

[0058] In an embodiment of the present utility model, the compressor cavity and the fan cavity are arranged in a first direction, the first direction is the thickness direction of the partition plate 10, the second direction is the width direction of the partition plate 10, and the height direction of the partition plate 10 is the up-down direction. The up-down direction is set as the third direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0059] Combined with Figure 6 , Figure 7 and Figure 9 As shown, the first cover 21 covers the side of the first ventilation opening 11 on the partition plate 10 facing the fan cavity. In this way, it can prevent the water in the fan cavity from being thrown out by the fan and splashing into the compressor cavity through the first ventilation opening 11, and it can prevent water droplets from appearing on the control board body of the electronic control box in the compressor cavity, thus ensuring the reliability of the devices on the control board body.

[0060] The first cover 21 may include a first back plate 213, and the first back plate 213 is spaced from the partition plate 10 in the first direction. In this way, not only can the first back plate 213 avoid the first ventilation opening 11 in the first direction to ensure the normal ventilation of the first ventilation opening 11, but also the first back plate 213 can block the rainwater from splashing into the first ventilation opening 11 from the fan cavity in the first direction, so as to achieve the water blocking effect of the waterproof cover 20 on the first ventilation opening 11 in the first direction.

[0061] The first cover 21 may include first side plates 214. There are two first side plates 214, and they are respectively arranged on both sides of the first back plate 213 in the second direction. The sides of the two first side plates 214 away from the first back plate 213 in the second direction are both connected to the partition plate 10. In this way, the first side plates 214 on both sides of the first back plate 213 in the second direction can block the rainwater from splashing into the first ventilation opening 11 from the fan cavity in the second direction, so as to achieve the water blocking effect of the first cover 21 on the first ventilation opening 11 in the second direction.

[0062] The first cover 21 may include a top plate 215. The top plate 215 is arranged on the top of the first back plate 213 and is located between the two first side plates 214. The side of the top plate 215 away from the first back plate 213 in the first direction is connected to the partition plate 10. In this way, it can prevent the rainwater in the fan cavity from splashing into the first ventilation opening 11 from the top of the waterproof cover 20.

[0063] In summary, by setting the first cover 21 to include the first back plate 213, two first side plates 214, and the top plate 215, it can effectively block the rainwater in the fan cavity from entering the first ventilation opening 11 from the first direction, the second direction, and above. Moreover, the air flowing out of the compressor cavity through the first ventilation opening 11 can flow out from the bottom of the first cover 21 to ensure the air circulation in the compressor cavity.

[0064] Further, the first housing 21 may further include a grille 216. The grille 216 is disposed at the bottom of the first back plate 213 and between the two first side plates 214. The top plate 215, the first back plate 213, the two first side plates 214, and the grille 216 jointly define an air guiding channel 211, and the grille 216 has a ventilation function. This can not only ensure the flow reliability of the air flow in the air guiding channel 211, but also enable the first housing 21 to have an insect prevention function.

[0065] Combined Figure 6 、 Figure 7 and Figure 9 As shown in, the second housing 22 is disposed below the first housing 21. This can enable the second housing 22 to protect the second ventilation opening 212 in the first housing 21, prevent the second ventilation opening 212 from being directly exposed in the fan cavity, and effectively prevent rainwater in the fan cavity from passing through the second ventilation opening 212 and then entering the air guiding channel 211.

[0066] The second housing 22 may include a second back plate 222. The second back plate 222 is spaced from the partition 10 in the first direction and is connected to the lower end of the first back plate 213. This can not only enable the second back plate 222 to block rainwater in the fan cavity from splashing onto the second ventilation opening 212 along the first direction, but also enable the air flowing out of the second ventilation opening 212 to flow into the ventilation air duct to ensure the air circulation between the air guiding channel 211 and the ventilation channel 221.

[0067] The second housing 22 may include second side plates 223. There are two second side plates 223, and the two second side plates 223 are disposed on both sides of the second back plate 222 in the second direction. This can enable the second side plates 223 on both sides of the second back plate 222 in the second direction to block rainwater from splashing into the second ventilation opening 212 from the fan cavity along the second direction, so as to achieve the water blocking effect of the second housing 22 on the second ventilation opening 212 in the second direction.

[0068] The second housing 22 may include a bottom plate 224. The bottom plate 224 is disposed at the bottom of the second back plate 222 and between the two second side plates 223. This can enable the second back plate 222, the two second side plates 223, and the bottom plate 224 to jointly define a ventilation channel 221.

[0069] Further, the bottom plate 224 is disposed towards the partition 10 in the first direction, and the bottom plate 224 and the two second side plates 223 are both spaced from the partition 10 in the first direction.

[0070] With such a setting, on the one hand, the bottom plate 224 can block at least part of the second ventilation opening 212 to prevent rainwater in the fan cavity from entering the air guiding channel 211 through the second ventilation opening 212. On the other hand, it can ensure that the ventilation channel 221 is connected to the fan cavity, so that while the compressor cavity and the fan cavity are normally ventilated, rainwater can be effectively prevented from entering the compressor cavity.

[0071] In the embodiment of the present utility model, the first cover body 21 and the second cover body 22 are integrally formed structural members. On the one hand, this can ensure the structural reliability of the first cover body 21 and the second cover body 22, and further ensure the structural strength of the waterproof cover 20, which is beneficial to improving the waterproof reliability of the waterproof cover 20 for the first ventilation opening 11. On the other hand, it can simplify the production process of the waterproof cover 20, which is beneficial to improving the production efficiency of the outdoor unit of the air conditioner.

[0072] Join Figure 6 and Figure 9 As shown, there are multiple grilles 216, and sub-ventilation openings 2122 are defined between adjacent two grilles 216, and there are multiple sub-ventilation openings 2122.

[0073] Specifically, after the second ventilation opening 212 is formed in the grille 216, multiple grilles 216 can be arranged in the second ventilation opening 212, and the multiple grilles 216 are sequentially spaced along the first direction. On the one hand, this can enable the multiple grilles 216 to block larger objects in the ventilation channel 221 from entering the air guiding channel 211, such as insects, dust particles, etc. On the other hand, multiple sub-ventilation openings 2122 can be defined between the multiple grilles 216, so as to ensure the air flow between the air guiding channel 211 and the ventilation channel 221.

[0074] Furthermore, since the bottom plate 224 and the two second side plates 223 are both spaced from the partition 10, in extremely harsh rainy weather, the rainwater entering the fan cavity may splash into the ventilation channel 221 from the partition 10. By arranging multiple spaced grilles 216 in the second ventilation opening 212 between the ventilation channel 221 and the air guiding channel 211, multiple sub-ventilation openings 2122 can be formed between the multiple grilles 216. This can not only ensure the air flow between the air guiding channel 211 and the ventilation channel 221, but also effectively prevent rainwater from entering the air guiding channel 211, thereby improving the protection effect of the waterproof cover 20.

[0075] According to the embodiment of the present utility model, the total area of the multiple sub-ventilation openings 2122 is S1, and the area of the second ventilation opening 212 is S2, and S1 and S2 satisfy the relational expression: 0.5S2 ≤ S1 ≤ S2.

[0076] In some specific embodiments of the present utility model, the total area of a plurality of sub-ventilation openings 2122 is S1, and the area of the second ventilation opening 212 is S2. S1 and S2 satisfy the relationship: 0.5S2 ≤ S1.

[0077] That is to say, the total area of a plurality of sub-ventilation openings 2122 is not less than the first parameter value. If the total area of a plurality of sub-ventilation openings 2122 is less than the first parameter value, the ventilation effect of the second ventilation opening 212 will be affected, which will cause the air flow in the compressor chamber to be blocked when flowing to the fan chamber, resulting in a slowdown of the air flow rate in the compressor chamber, and further leading to a poor heat dissipation effect of the electronic control box. Among them, the range of the first parameter value is 0.4S2 - 0.6S2. For example, the first parameter value can be 0.5S2. When the total area of a plurality of sub-ventilation openings 2122 is set to be half of the area of the second ventilation opening 212, the ventilation effect of the waterproof cover 20 can be improved to ensure the heat dissipation efficiency of the electronic control box.

[0078] In some specific embodiments of the present utility model, the total area of a plurality of sub-ventilation openings 2122 is S1, and the area of the second ventilation opening 212 is S2. S1 and S2 satisfy the relationship: S1 ≤ S2.

[0079] That is to say, the total area of a plurality of sub-ventilation openings 2122 does not exceed the second parameter value. If the total area of a plurality of sub-ventilation openings 2122 exceeds the second parameter value, the first housing 21 and the second housing 22 will be disconnected, and the protective effect of the waterproof cover 20 on the second ventilation opening 212 will fail. Among them, the range of the second parameter value is 0.9S2 - S2. For example, the second parameter value can be S2. When the total area of a plurality of sub-ventilation openings 2122 is set to be equal to the area of the second ventilation opening 212, no grille 216 is provided in the second ventilation opening 212. At this time, the ventilation volume of the second ventilation opening 212 is the largest, and thus the heat dissipation effect of the compressor chamber can be improved.

[0080] According to the embodiments of the present utility model, in combination with Figure 9 As shown, the spacing distance H between two adjacent grilles 216 in the first direction is set, and H satisfies the relationship: H ≤ 3 mm.

[0081] In some specific embodiments of the present utility model, the spacing distance between two adjacent grilles 216 in the first direction is not greater than the third parameter value. If the spacing distance between two adjacent grilles 216 in the first direction is greater than the third parameter value, insects or dust particles may enter the air guiding channel 211 through the sub-vent 2122 and then enter the compressor chamber, affecting the normal operation of the electronic control box. Among them, the range of the third parameter value is 0 - 3 mm. For example, the second parameter value can be 2.5 mm. When the spacing distance between two adjacent grilles 216 in the first direction is set to 2.5 mm, the spacing distance between two adjacent grilles 216 in the first direction can be made smaller, which is conducive to improving the insect prevention effect of the waterproof cover 20 and can also make the second vent 212 have better ventilation efficiency.

[0082] Combined with Figure 6 and Figure 7 As shown, a first arc-shaped transition plate 217 is connected between the first back plate 213 and the top plate 215, and a second arc-shaped transition plate 225 is connected between the second back plate 222 and the bottom plate 224.

[0083] Specifically, the first arc-shaped transition plate 217 has an arc-shaped structure. Setting the first arc-shaped transition plate 217 between the first back plate 213 and the top plate 215 can make the transition between the first back plate 213 and the top plate 215 adopt an arc-shaped structure. In this way, not only can the air resistance of the air flow in the fan chamber flowing to the connection between the first back plate 213 and the top plate 215 be reduced, but also it is beneficial to reducing the production materials of the waterproof cover 20. Therefore, the setting of the first arc-shaped transition plate 217 is conducive to increasing the air flow velocity in the fan chamber and reducing the production cost of the waterproof cover 20.

[0084] The second arc-shaped transition plate 225 has an arc-shaped structure. Setting the second arc-shaped transition plate 225 between the second back plate 222 and the bottom plate 224 can make the transition between the second back plate 222 and the bottom plate 224 adopt an arc-shaped structure. In this way, not only can the air resistance of the air flow in the fan chamber flowing to the connection between the second back plate 222 and the bottom plate 224 be reduced, but also it is beneficial to reducing the production materials of the waterproof cover 20. Therefore, the setting of the second arc-shaped transition plate 225 is conducive to increasing the air flow velocity in the fan chamber and reducing the production cost of the waterproof cover 20.

[0085] Combined with Figures 6 - 8 As shown, a limiting flange 218 is provided on the circumferential edge of the first housing 21 corresponding to the open side of the air guiding channel 211, and the limiting flange 218 is mutually attached to the outer side of the circumferential edge of the partition 10 corresponding to the first vent 11.

[0086] Specifically, in the first cover 21, limiting flanges 218 are provided at the circumferential edges of the top plate 215 and the two first side plates 214 corresponding to the open side of the air guiding channel 211. By fitting the limiting flanges 218 with the outer side of the partition 10 corresponding to the first ventilation opening 11, the contact area between the top plate 215, the two first side plates 214 and the partition 10 can be increased.

[0087] It can be understood that when the contact area between the top plate 215, the two first side plates 214 and the partition 10 increases, the contact between the top plate 215, the two first side plates 214 and the partition 10 will be more stable, which can improve the connection stability between the first cover 21 and the partition 10, and thus ensure the connection stability between the air guiding channel 211 and the first ventilation opening 11.

[0088] Furthermore, the limiting flanges 218 can also improve the connection tightness between the top plate 215, the two first side plates 214 and the partition 10, which can effectively prevent water from entering the compressor cavity through the top plate 215, the two first side plates 214 and the partition 10, thus being beneficial to improving the waterproof effect of the waterproof cover 20.

[0089] Combined Figure 6 and Figure 8 As shown, at least part of the open side of the first cover 21 corresponding to the air guiding channel 211 is provided with elastic limiting hooks 2181, and a limiting piece 12 is provided at the edge of the partition 10 corresponding to the first ventilation opening 11. The elastic limiting hooks 2181 and the limiting piece 12 are selectively elastically hooked and matched.

[0090] Specifically, at least part of the open side of the first cover 21 corresponding to the air guiding channel 211 is provided with elastic limiting hooks 2181, which can be hooked and matched with the edge of the partition 10 corresponding to the first ventilation opening 11, so as to limit the installation position of the first cover 21 on the partition 10, which can not only ensure the structural reliability of the waterproof cover 20 on the partition 10, but also improve the installation convenience of the waterproof cover 20 and the partition 10.

[0091] Furthermore, a limiting piece 12 is provided at the edge of the partition 10 corresponding to the first ventilation opening 11, and the elastic limiting hooks 2181 and the limiting piece 12 are selectively elastically hooked and matched. With this setting, the limiting piece 12 can ensure the cooperation reliability between the elastic limiting hooks 2181 and the partition 10.

[0092] In the embodiment of the present utility model, the limiting piece 12 extends from the edge of the partition 10 corresponding to the first ventilation opening 11 in the first direction towards the compressor cavity, and the elastic limiting hooks 2181 extend from one of the two first side plates 214 in the first direction towards the side away from the first back plate 213.

[0093] When installing the waterproof cover 20, the waterproof cover 20 can be pushed towards the compressor chamber in the first direction, so that the elastic limit hook 2181 enters the compressor chamber, and then is hooked and cooperated with the limit piece 12.

[0094] After the elastic limit hook 2181 enters the compressor chamber and contacts the limit piece 12, the elastic limit hook 2181 is squeezed by the limit piece 12 and undergoes a certain amount of deformation under the action of its own elasticity, so that the elastic limit hook 2181 continues to move in the first direction. At this time, the end of the elastic limit hook 2181 entering the compressor chamber is in sliding cooperation with the limit piece 12.

[0095] Until the elastic limit hook 2181 moves to the end of the limit piece 12 away from the partition 10 in the first direction, the extrusion force of the limit piece 12 on the elastic limit hook 2181 disappears. Then, the elastic limit hook 2181 resets and is hooked and cooperated with the end of the limit piece 12 away from the partition 10 in the first direction.

[0096] In this way, after the elastic limit hook 2181 is engaged with the limit piece 12, the limit piece 12 and the elastic limit hook 2181 are mutually limited in the first direction, which can prevent the first cover body 21 from detaching from the partition 10 in the first direction, thereby ensuring the reliability of the installation of the waterproof cover 20 on the partition 10.

[0097] Furthermore, the structures of the elastic limit hook 2181 and the limit piece 12 are simple and the installation is convenient. This not only helps to reduce the processing cost of the waterproof cover 20 to reduce the production cost of the outdoor unit of the air conditioner, but also can improve the assembly efficiency of the outdoor unit of the air conditioner.

[0098] Combined with Figure 6 and Figure 8 As shown, at least part of the first cover body 21 corresponding to the open side of the air guiding channel 211 is provided with a positioning hook 2182, and the positioning hook 2182 is hooked and positioned in cooperation with at least part of the edge of the partition 10 corresponding to the first ventilation opening 11.

[0099] Specifically, in the embodiment of the present invention, the positioning hook 2182 is arranged on one of the two first side plates 214 and is oppositely arranged with the elastic limit hook 2181 in the second direction, so as to ensure the independent arrangement of the positioning hook 2182 and the elastic limit hook 2181.

[0100] When installing the waterproof cover 20, first insert the positioning hook 2182 into the compressor chamber and hook and position it in cooperation with at least part of the edge of the partition 10 corresponding to the first ventilation opening 11. In this way, the waterproof cover 20 can be positioned corresponding to the first ventilation opening 11 when installing the waterproof cover 20, so as to improve the installation convenience of the waterproof cover 20, and thus improve the assembly efficiency of the outdoor unit of the air conditioner.

[0101] Then, rotate the first cover body 21 on the side away from the positioning hook 2182 in the second direction, so that the elastic limit hook 2181 extends into the compressor cavity and cooperates with the limit piece 12. During the rotation of the first cover body 21, the first cover body 21 rotates around the up-down direction of the position where the positioning hook 2182 cooperates with the partition plate 10 as the axis. In this way, the partition plate 10 can provide reliable support for the first cover body 21, and the installation convenience and reliability of the first cover body 21 can be ensured.

[0102] Combined Figure 6 with Figure 8 As shown, at least part of the open side of the first cover body 21 corresponding to the air guide channel 211 is provided with a guide protrusion 2183. A guide inclined surface 21831 is provided on the guide protrusion 2183, and the guide inclined surface 21831 is in guiding cooperation with the edge of the partition plate 10 corresponding to the first ventilation opening 11.

[0103] Specifically, in the embodiment of the present utility model, the guide protrusion 2183 is located at the part corresponding to the open side of the first cover body 21 corresponding to the air guide channel 211 and opposite to the top plate 215. The guide inclined surface 21831 on the guide protrusion 2183 cooperates with the edge of the partition plate 10 to play a guiding role in the position of the waterproof cover 20 on the partition plate 10 when installing the waterproof cover 20. Thus, it can be ensured that the open side of the waterproof cover 20 corresponds to the first ventilation opening 11 of the partition plate 10, and in this way, the air circulation between the compressor cavity and the air guide channel 211 can be ensured.

[0104] Further, when installing the waterproof cover 20, first, the positioning hook 2182 is in positioning cooperation with the edge position of the partition plate 10 corresponding to the first ventilation opening 11, and then the waterproof cover 20 is rotated around the up-down direction of the position where the positioning hook 2182 cooperates with the partition plate 10 as the axis. During this process, the guide inclined surface 21831 on the guide protrusion 2183 is in guiding cooperation with the edge of the partition plate 10 corresponding to the first ventilation opening 11.

[0105] With such a setting, not only is it convenient for the assembly of the waterproof cover 20 and the partition plate 10, but also the waterproof cover 20 can be prevented from moving up and down, so as to ensure that the open side of the waterproof cover 20 accurately corresponds to the first ventilation opening 11, the assembly convenience of the waterproof cover 20 can be ensured, and the assembly efficiency of the outdoor unit of the air conditioner can be improved.

[0106] After the waterproof cover 20 is fixed on the partition plate 10, it can be ensured that the air guide channel 211 is communicated with the first ventilation opening 11, and it can be ensured that the air flow entering the air guide channel 211 from the first ventilation opening 11 is the maximum air volume. Furthermore, it is beneficial to ensure the ventilation efficiency between the compressor cavity and the fan cavity, and the heat dissipation effect of the electric control box can be ensured.

[0107] Combined Figure 7 with Figure 11As shown in the figure, a first perforation 2184 is provided on the first cover body 21 corresponding to the open side of the air guide channel 211. A second perforation 13 is provided on the partition plate 10. The first perforation 2184 and the second perforation 13 are correspondingly arranged and are connected and fixed by a fastener 30.

[0108] Specifically, after the elastic limit hook 2181 of the waterproof cover 20 and the limit piece 12 of the partition plate 10 are hooked and matched, the first perforation 2184 on the waterproof cover 20 and the second perforation 13 on the partition plate 10 correspond to each other. Then, the fastener 30 passes through the first perforation 2184 and the second perforation 13 in sequence, and the fastener 30 is tightened, which can improve the connection reliability between the waterproof cover 20 and the partition plate 10.

[0109] Combined Figure 5 and Figure 6 As shown in the figure, a contact column 226 is provided on the side of the bottom of the second cover body 22 facing the partition plate 10. The contact column 226 is in contact and limit fit with the partition plate 10.

[0110] Specifically, the bottom of the bottom plate 224 and the two second side plates 223 are spaced from the partition plate 10 in the first direction, and the bottom of the bottom plate 224 and the two second side plates 223 is the air outlet position of the ventilation channel 221. The air flow here will cause the bottom of the bottom plate 224 and the two second side plates 223 to shake, which will not only affect the structural reliability of the waterproof cover 20 in the outdoor unit of the air conditioner, but also increase the noise of the outdoor unit of the air conditioner.

[0111] In the embodiment of the present invention, a contact column 226 extending in the first direction is provided on the side of the bottom of the second cover body 22 facing the partition plate 10. The contact column 226 can be in contact with the partition plate 10, so that the contact column 226 can play a reliable supporting role for the bottom of the second cover body 22, can increase the structural stability of the bottom of the second cover body 22, and further can improve the structural reliability of the waterproof cover 20, which is beneficial to reducing the noise of the outdoor unit of the air conditioner.

[0112] Next, refer to the attached Figures 1 - 11 Describe the outdoor unit 100 of the air conditioner according to the embodiment of the present invention.

[0113] As Figures 1 - 4 shown, the outdoor unit of the air conditioner according to the embodiment of the present invention includes a housing, an outdoor heat exchanger, an outdoor fan assembly, a compressor, an electric control box, and a waterproof cover 20.

[0114] The housing is arranged in an outdoor environment, allowing outdoor air to enter the housing, facilitating heat exchange between the outdoor air and the outdoor heat exchanger. The housing is provided with an air inlet and an air outlet. The outdoor heat exchanger is disposed inside the housing, and the outdoor fan assembly is disposed inside the housing and on one side of the outdoor heat exchanger. The outdoor fan assembly drives the outdoor air to enter the housing through the air inlet, and after the outdoor air exchanges heat with the outdoor heat exchanger to form a heat exchange airflow, it is driven by the outdoor fan assembly to flow out of the housing through the air outlet.

[0115] In this way, the outdoor unit of the air conditioner can selectively control the outdoor air to enter the housing through the air inlet, and the outdoor air can exchange heat with the outdoor heat exchanger to form a heat exchange airflow, and then be driven by the fan assembly to flow out of the housing through the air outlet, thereby realizing cooling or heating for the interior.

[0116] The compressor is disposed inside the housing, and the compressor is interconnected with the outdoor heat exchanger, so that the refrigerant can form a circuit between the compressor and the outdoor heat exchanger, enabling the refrigerant to circulate and exchange heat normally in the outdoor unit of the air conditioner.

[0117] The electric control box is disposed inside the housing, and the housing can protect the electric control box to prevent outdoor dust and rain from entering the electric control box. In this way, the working safety of the electric control box can be ensured.

[0118] According to an embodiment of the present invention, a fan cavity and a compressor cavity are formed inside the housing. Among them, the outdoor fan assembly is disposed in the fan cavity, so that the outdoor fan assembly operates in the fan cavity to generate negative pressure, which can suck the outdoor air into the fan cavity and exchange heat with the outdoor heat exchanger.

[0119] Both the compressor and the electric control box are disposed in the compressor cavity. A partition 10 is provided between the fan cavity and the compressor cavity. The partition 10 can separate the fan cavity and the compressor cavity, so that the compressor and the electric control box can be separated from the components in the fan cavity, and can play a protective role for the compressor and the electric control box.

[0120] Furthermore, a first ventilation opening 11 is formed on the partition 10, so that the air between the compressor cavity and the fan cavity can be connected. When the outdoor fan assembly works in the fan cavity and generates negative pressure, the air in the compressor cavity can form an air flow and be sucked into the fan cavity through the first ventilation opening 11. In this way, the heat generated by the electric control box in the compressor cavity can follow the air and enter the fan cavity through the first ventilation opening 11, so as to dissipate heat from the electric control box and ensure the working reliability of the electric control box.

[0121] It can be understood that when the outdoor unit of the air conditioner is exposed to rain, the rainwater can enter the interior of the housing through the air inlet and the air outlet. The partition 10 is provided to separate the compressor and the electric control box, which can not only ensure the operation reliability of the compressor, but also prevent the rainwater from appearing on the control board body of the electric control box, thus being beneficial to protecting the safety of the electric control box.

[0122] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown, in the embodiment of the present utility model, a waterproof cover 20 is arranged in the fan cavity, and the waterproof cover 20 is connected to the partition 10, which can ensure the structural stability of the waterproof cover 20 in the outdoor unit of the air conditioner.

[0123] Furthermore, the waterproof cover 20 includes a ventilation channel 221, and the ventilation channel 221 has an air outlet opening towards the partition 10. In this way, under the action of negative pressure in the fan cavity, the air flow in the compressor cavity can flow into the waterproof cover 20 from the first ventilation opening 11 and flow to the fan cavity from the air outlet, thereby dissipating heat from the compressor cavity.

[0124] Furthermore, a grille 216 is arranged between the first ventilation opening 11 and the air outlet of the ventilation channel 221. In this way, it can not only prevent rainwater from entering the air guide channel 211 through the second ventilation opening 212, improve the waterproof effect of the air guide channel 211, but also block flying insects and dust particles in the fan cavity from entering the air guide channel 211 through the second ventilation opening 212, enabling the waterproof cover 20 to have an insect-proof function while ensuring ventilation.

[0125] Thus, in the embodiment of the present utility model, the waterproof cover 20 can not only ensure the normal heat dissipation of the electric control box, but also effectively prevent rainwater, flying insects and dust particles in the fan cavity from entering the compressor cavity to ensure the safety of the electric control box.

[0127] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present utility model, and the scope of the present utility model is defined by the claims and their equivalents.
