[0031] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0032] Next, refer to the attached Figures 1-5 Describe the outdoor unit 100 of the air conditioner according to an embodiment of the present utility model.

[0033] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the outdoor air conditioner 100 according to an embodiment of the present utility model includes: a housing 10 and an electric control box 20. Specifically, a ventilation opening 111 is provided on the housing 10, and the ventilation opening 111 communicates with the external space; a heat dissipation flow channel 23 having an air inlet 21 and an air outlet 22 is formed in the electric control box 20, the air inlet 21 communicates with the ventilation opening 111, and the heating element 60 in the electric control box 20 is located in the heat dissipation flow channel 23. At least one water blocking rib 24 is formed in the heat dissipation flow channel 23, that is to say, one, two, three or more water blocking ribs 24 can be formed in the heat dissipation flow channel 23.

[0034] For example, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a ventilation opening 111 is provided on the right side of the housing 10, the ventilation opening 111 communicates with the external space and the interior of the housing 10, the electric control box 20 is disposed in the housing 10, a heat dissipation flow channel 23 is formed in the electric control box 20, the right end of the heat dissipation flow channel 23 communicates with the air inlet 21, and the left end of the heat dissipation flow channel 23 communicates with the air outlet 22.

[0035] When dissipating heat from the heating element 60 in the electric control box 20, the outdoor air conditioner 100 operates, the fan 50 rotates to generate negative pressure, the air flow in the external space enters the air inlet 21 through the ventilation opening 111, and then the air flow flows from the air inlet 21 into the heat dissipation flow channel 23. The water vapor in the air flow is blocked by the water blocking rib 24, and then the air in the air flow blows towards the heating element 60 to blow the heat generated by the heating element 60 to the air outlet 22. After that, the air flow and heat flow out of the heat dissipation flow channel 23 through the air outlet 22 to the radiator 40. The fan 50 continues to operate, and the air flow in the external space continuously blows towards the heating element 60 until the temperature of the heating element 60 drops to a reasonable temperature. At this time, the heat dissipation work of the heating element 60 in the electric control box 20 is completed.

[0036] In the outdoor air conditioner 100 of the present utility model, the water blocking rib 24 is arranged in the heat dissipation flow channel 23. When dissipating heat from the heating element 60, the water vapor in the air flow can be prevented from blowing onto the heating element 60, so that the heating element 60 in the electric control box 20 can be prevented from short-circuiting after contacting with the water vapor, and thus the safety of the electric control box 20 can be ensured. At the same time, the structure of the water blocking rib 24 is simple and convenient to process, so that the production of the electric control box 20 can be facilitated, and the processing efficiency of the electric control box 20 can be effectively improved. In addition, the heat dissipation flow channel 23 communicates with the external space through the ventilation opening 111, which can ensure the air intake volume in the heat dissipation flow channel 23, so that the heat dissipation effect of the heating element 60 can be ensured, and thus the heat dissipation requirement under high temperature working conditions can be met.

[0037] The outdoor unit 100 of an air conditioner according to an embodiment of the present invention is provided with a water baffle rib 24 in the heat dissipation flow channel 23, which can prevent the water vapor in the air flow from blowing onto the heating element 60, thereby ensuring the safety of the electronic control box 20. At the same time, the heat dissipation flow channel 23 communicates with the external space through the ventilation opening 111, which can ensure the air intake volume in the heat dissipation flow channel 23, thereby ensuring the heat dissipation effect of the heating element 60.

[0038] According to some embodiments of the present invention, with reference to Figure 3 and Figure 4 , a plurality of water baffle ribs 24 are provided in the heat dissipation flow channel 23. That is to say, two, three, four or more water baffle ribs 24 are provided in the heat dissipation flow channel 23. The plurality of water baffle ribs 24 are arranged at intervals along the flow direction of the heat dissipation flow channel 23. The plurality of water baffle ribs 24 include a first rib 241 and a second rib 242. The first rib 241 and the second rib 242 are respectively connected to two opposite side walls of the heat dissipation flow channel 23 and are alternately arranged in the extending direction of the heat dissipation flow channel 23.

[0039] In this way, the plurality of water baffle ribs 24 can further ensure the effect of blocking the water vapor in the air flow, thereby effectively preventing the heating element 60 from being eroded by the water vapor in the air flow. At the same time, the setting positions of the first rib 241 and the second rib 242 are reasonable, thereby ensuring the water blocking effect of the water baffle rib 24 again.

[0040] For example, as shown in Figure 3 and Figure 4 , a plurality of water baffle ribs 24 are provided in the heat dissipation flow channel 23, and the air flow flows from right to left. The plurality of water baffle ribs 24 are arranged at intervals in the left-right direction. It can be that the first rib 241 is connected to the top wall of the heat dissipation flow channel 23 and the second rib 242 is connected to the bottom wall of the heat dissipation flow channel 23, or the second rib 242 is connected to the top wall of the heat dissipation flow channel 23 and the first rib 241 is connected to the bottom wall of the heat dissipation flow channel 23.

[0041] According to some alternative embodiments of the present invention, with reference to Figure 3 and Figure 4 , the first rib 241 is connected to the top wall of the heat dissipation flow channel 23 and extends downward, the second rib 242 is connected to the bottom wall of the heat dissipation flow channel 23 and extends upward, and the lower end edge of the first rib 241 extends downward beyond the upper end edge of the adjacent second rib 242.

[0042] In this way, in the radial direction of the heat dissipation flow channel 23, the first rib 241 and the second rib 242 have an overlapping area, thereby blocking the heat dissipation flow channel 23 in the radial direction of the heat dissipation flow channel 23. Therefore, when the air flow flows along the extending direction of the heat dissipation flow channel 23, the air flow in the heat dissipation flow channel 23 will flow to the heating element 60 only after passing through the blocking action of the first rib 241 or the second rib 242, and thus the use safety of the heating element 60 can be effectively ensured.

[0043] For example, as Figure 3 and Figure 4 shown, the upper end of the first rib 241 is connected to the top wall of the heat dissipation channel 23, the lower end of the first rib 241 extends downward, the lower end of the second rib 242 is connected to the bottom wall of the heat dissipation channel 23, and the upper end of the second rib 242 extends upward.

[0044] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , the height difference in the vertical direction between the lower edge of the first rib 241 and the upper edge of the adjacent second rib 242 arranged adjacent thereto is greater than or equal to 5 mm. Thus, by defining the height difference between the first rib 241 and the second rib 242, it can be ensured that the air flow passing through the heat dissipation channel will flow to the heating element 60 only after being blocked by the water blocking rib 24, and further, the use safety of the electric control box 20 can be ensured.

[0045] For example, as Figure 3 and Figure 4 shown, the height difference in the vertical direction between the lower edge of the first rib 241 and the upper edge of the adjacent second rib 242 arranged adjacent thereto can be: 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm.

[0046] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , the heat dissipation channel 23 includes: a first section 231 and a second section 232. One end of the first section 231 (such as the right end of the first section 231 shown in Figure 4 ) is connected to the air inlet 21 and the other end (such as the left end of the first section 231 shown in Figure 4 ) extends upward obliquely; one end of the second section 232 (such as the right end of the second section 232 shown in Figure 4 ) is connected to the other end of the first section 231, and the other end of the second section 232 (such as the left end of the second section 232 shown in Figure 4 ) extends downward obliquely, wherein the bottom wall of the heat dissipation channel 23 at the connection position between the first section 231 and the second section 232 forms the water blocking rib 24.

[0047] In this way, by defining the extension forms of the first section 231 and the second section 232, the first section 231 and the second section 232 cooperate to form a structure protruding upward. When the air flow flows from the air inlet 21 to the heat dissipation channel 23, the air flow will first be blocked by the bottom wall of the first section 231, so that water vapor can be prevented from entering the second section 232 from the first section 231. At the same time, the water blocking rib 24 on the bottom wall at the connection position between the first section 231 and the second section 232 can block the air flow for the second time. Therefore, the effect of the water blocking rib 24 in blocking water vapor can be ensured.

[0048] For example, as Figure 3 andFigure 4 As shown, the first section 231 extends in the left-right direction, the right end of the first section 231 is connected to the air inlet 21, the left end of the first section 231 extends upward at an angle, the second section 232 extends in the left-right direction, the right end of the second section 232 is connected to the left end of the first section 231, the left end of the second section 232 extends downward at an angle, and the first section 231 and the second section 232 form a V-shaped structure protruding upward.

[0049] Furthermore, if Figure 3 and Figure 4 As shown, the other end of the second segment 232 (such as Figure 4 The top wall of the left end of the second section 232 shown in the figure is provided with a water retaining rib 24 extending downward. Therefore, when the airflow passes through the water retaining rib 24 between the first section 231 and the second section 232, the airflow is at a high position in the radial direction of the heat dissipation channel. When the airflow continues to flow along the extension direction of the heat dissipation channel 23, the water retaining rib 24 at the other end of the second section 232 extends downward, so that the water retaining rib 24 can block the water vapor in the airflow again, thereby ensuring the heating element 60 in the electric control box 20.

[0050] For example, Figure 3 and Figure 4 As shown, the water retaining rib 24 at the left end of the second section 232 is a first rib 241, the first rib 241 is connected to the top wall of the second section 232, the first rib 241 extends downward from the top wall of the second section 232, and the water retaining rib 24 on the bottom wall at the connection position between the left end of the first section 231 and the right end of the second section 232 is formed as a second rib 242.

[0051] According to some optional embodiments of the present invention, referring to Figure 3 and Figure 4 The electric control box 20 is formed with a receiving chamber 25, the receiving chamber 25 and the second section 232 facing away from the end of the first section 231 (such as Figure 4 The left end of the second section 232 is connected to the housing cavity 25, and the heating element 60 is arranged in the housing cavity 25. Therefore, the airflow can flow from the second section 232 to the housing cavity 25, so that the heating element 60 in the housing cavity 25 can be cooled, and the heat dissipation requirement of the heating element 60 can be guaranteed. At the same time, the housing cavity 25 provides a layout space for the heating element 60, so that the layout of the heating element 60 can be facilitated.

[0052] For example, Figure 3 and Figure 4 As shown, the right end of the accommodating cavity 25 is communicated with the left end of the second section 232 , the heating element 60 is disposed in the accommodating cavity 25 , and the left end of the accommodating cavity 25 is communicated with the air outlet 22 .

[0053] According to some embodiments of the present invention, referring to Figure 3 and Figure 5, the ventilation opening 111 penetrates through the housing 10 in the thickness direction of the housing 10 (such as Figure 5 the left - right direction shown), the ventilation opening 111 includes: a first ventilation opening 1111 and a second ventilation opening 1112, and the first ventilation opening 1111 and the second ventilation opening 1112 are arranged at intervals on the housing 10. Thus, the structural form of the ventilation opening 111 is simple, which can facilitate the processing of the ventilation opening 111. At the same time, multiple ventilation openings 111 can ensure the air intake volume of the ventilation opening 111, so as to ensure the heat dissipation requirements of the heating element 60.

[0054] For example, as Figure 3 and Figure 5 shown, the ventilation opening 111 penetrates through the housing 10 in the left - right direction, and the first ventilation opening 1111 is arranged on the upper side of the second ventilation opening 1112.

[0055] According to some alternative embodiments of the present utility model, referring to Figure 3 and Figure 5 , the housing 10 further includes: a housing main body 11 and a baffle 12. The electric control box 20 is arranged inside the housing main body 11. Both the first ventilation opening 1111 and the second ventilation opening 1112 are formed on the side wall of the housing main body 11. The baffle 12 is arranged inside the housing main body 11, and an air inlet flow channel 13 is formed between the baffle 12 and the housing main body 11. The air inlet flow channel 13 communicates with the second ventilation opening 1112 and the air inlet 21.

[0056] In this way, the internal structure of the air conditioner outdoor unit 100 can be arranged inside the housing main body 11, so as to protect the internal structure of the air conditioner outdoor unit 100. At the same time, the baffle 12 and the housing main body 11 cooperate to strengthen the strength of the housing main body 11 and prevent the housing main body 11 from being damaged. Moreover, the air inlet flow channel 13 is formed by the baffle 12 and the housing main body 11, and there is no need to additionally process the air inlet flow channel 13, so as to reduce the processing steps and improve the preparation efficiency.

[0057] For example, as Figure 3 and Figure 5 shown, both the first ventilation opening 1111 and the second ventilation opening 1112 are formed on the right - hand side plate of the housing main body 11. The baffle 12 is arranged inside the housing main body 11 and on the left side of the right - hand side plate of the housing main body 11. An air inlet flow channel 13 extending in the up - down direction is formed between the baffle 12 and the housing main body 11. The lower end of the air inlet flow channel 13 communicates with the second ventilation opening 1112, and the upper end of the air inlet flow channel 13 communicates with the air inlet 21.

[0058] According to some alternative embodiments of the present utility model, referring to Figure 3 and Figure 5 , the air conditioner outdoor unit 100 further includes: a power socket 30, and the power socket 30 is arranged on the side of the baffle 12 away from the air inlet flow channel 13 (such as Figure 5On the left side of the baffle 12 shown, the power socket 30 is fixed to the baffle 12. Thus, the baffle 12 can provide a fixed position for the power socket 30, facilitating the arrangement of the power socket 30. At the same time, the baffle 12 can protect the power socket 30, effectively preventing the water vapor in the air flow of the air inlet channel 13 from contacting the power socket 30, thereby ensuring the normal operation of the air conditioner outdoor unit 100.

[0059] An air conditioner according to an embodiment of the present invention, referring to Figure 1 , Figure 2 and Figure 3 , includes: the air conditioner outdoor unit 100 of the first aspect of this embodiment.

[0060] For the air conditioner according to an embodiment of the present invention, by providing the air conditioner outdoor unit 100 of the first aspect of this embodiment and arranging a water retaining rib 24 in the heat dissipation channel 23, the water vapor in the air flow can be prevented from blowing onto the heating element 60, thus ensuring the safety of the electric control box 20. At the same time, the heat dissipation channel 23 communicates with the external space through the ventilation opening 111, which can ensure the air intake volume in the heat dissipation channel 23, thereby ensuring the heat dissipation effect of the heating element 60.

[0061] Next, refer to Figures 1-5 to describe the air conditioner according to an embodiment of the present invention.

[0062] The air conditioner according to an embodiment of the present invention, as Figure 2 shown, includes an air conditioner outdoor unit 100, and the air conditioner outdoor unit 100 includes: a housing 10, an electric control box 20, a power socket 30, a radiator 40, and a fan 50. The electric control box 20, the power socket 30, the radiator 40, and the fan 50 are arranged inside the housing 10.

[0063] The housing 10 includes a housing main body 11 and a baffle 12. A ventilation opening 111 is provided on the right side plate of the housing 10. The ventilation opening 111 includes a first ventilation opening 1111 and a second ventilation opening 1112. The first ventilation opening 1111 is located above the second ventilation opening 1112. The first ventilation opening 1111 penetrates the right side plate of the housing main body 11 in the left-right direction. The baffle 12 is arranged on the left side of the right side plate of the housing main body 11, and the power socket 30 is fixed to the left side of the baffle 12. An air inlet channel 13 is formed between the baffle 12 and the right side plate of the housing main body 11. The air inlet channel 13 extends in the up-down direction, and the lower end of the air inlet channel 13 communicates with the second ventilation opening 1112.

[0064] An air inlet 21, an air outlet 22, and a heat dissipation channel 23 are formed inside the electric control box 20. The right end of the heat dissipation channel 23 communicates with the first ventilation opening 1111 and the upper end of the air inlet channel 13 through the air inlet 21. The left end of the heat dissipation channel 23 communicates with the air outlet 22, and the air outlet 22 communicates with the radiator 40 and the fan 50.

[0065] The heat dissipation channel 23 includes: a first section 231 and a second section 232. The right end of the first section 231 is connected to the air inlet 21 and the left end extends obliquely upward. The right end of the second section 232 is connected to the left end of the first section 231, and the left end of the second section 232 extends obliquely downward. A first rib 241 is formed on the top wall of the right end of the second section 232. The first rib 241 extends downward from the top wall of the second section 232. The bottom wall at the connection position of the first section 231 and the second section 232 is formed as a second rib 242. The lower end edge of the first rib 241 extends beyond the upper end edge of the adjacent second rib 242.

[0066] The electronic control box 20 is provided with a receiving cavity 25. The heating element 60 is arranged in the receiving cavity 25. The left end of the receiving cavity 25 communicates with the right end of the second section 232, and the right end of the receiving cavity 25 communicates with the air outlet 22.

[0067] When dissipating heat from the heating element 60, the fan 50 operates to generate negative pressure. The air flow in the external space can enter the air inlet 21 from the first ventilation opening 1111 or enter the air inlet 21 through the air inlet flow channel 13 from the second ventilation opening 1112. After that, the air flow enters the first section 231 of the heat dissipation channel 23. At this time, the second rib 242 blocks the water vapor in the air flow in the first section 231. Then, the air flow flows through the second rib 242 to the second section 232. The first rib 241 at the right end of the second section 232 blocks the water vapor in the air flow. After that, the air flow flows from the second section 232 to the receiving cavity 25. Then, the heat dissipated by the heating element 60 in the receiving cavity 25 is blown by the air flow to the air outlet 22. After that, the air flow flows from the air outlet 22 to the radiator 40. The fan 50 continues to operate until the temperature of the heating element 60 drops to a reasonable temperature. At this time, the heat dissipation work of the heating element 60 is completed.
