[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0044] The following is for reference. Figures 1-10 The electronic control component 10 according to a first aspect embodiment of the present invention is described.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 10 As shown, the electronic control assembly 10 according to the first aspect of the present invention is used in the outdoor unit 1 of an air conditioner and includes: an electronic control box 11, a partition plate 12, a wind deflector 13, a radiator 14, an electronic control board 15, and an electronic control unit 16.

[0046] Specifically, the control box 11 has an air inlet 113 and an air outlet 114. A partition plate 12 is disposed inside the control box 11 and divides the space inside the control box 11 into a first cavity 111 and a second cavity 112 arranged to the left and right. The air inlet 113 is connected to the first cavity 111 and the air outlet 114 is connected to the second cavity 112. The partition plate 12 has a plurality of ventilation holes 121 that penetrate the partition plate 12 in the left and right direction. The baffle plate 13 is connected to the partition plate 12 and is disposed in the first cavity 111. In the projection plane perpendicular to the left and right direction, the baffle plate 13 blocks the ventilation holes 121 formed in the upper area of ​​at least the front end of the partition plate 12. The control plate 15 is disposed inside the control box 11. The radiator 14 and the control unit 16 are both connected to the lower side of the control plate 15. The control unit 16 is disposed in the first cavity 111 and the radiator 14 is disposed in the second cavity 112 and is suitable for being disposed in the fan wheel compartment 21 of the outdoor unit 1 of the air conditioner.

[0047] The wind deflector 13 can block the ventilation holes 121 formed in the upper region of the front end of the partition plate 12. The wind deflector 13 can also block the ventilation holes 121 formed in the upper region of the partition plate 12. The wind deflector 13 can also block the ventilation holes 121 on the entire partition plate 12. It should be noted that the wind deflector 13 blocks the ventilation holes 121, but does not close the ventilation holes 121. Airflow can flow around the wind deflector 13 through the gap between the partition plate 12 and the wind deflector 13.

[0048] The control board 15 is supported on the upper side of the partition plate 12. One end of the control board 15 extends into the first cavity 111 and the other end extends into the second cavity 112. The control component 16 is connected to the lower side of the portion of the control board 15 that extends into the first cavity 111. The heat sink 14 is connected to the lower side of the portion of the control board 15 that extends into the second cavity 112. In this way, the control component 16 and the control board 15 are located on the upper part of the first cavity 111.

[0049] After the electronic control component 10 is assembled onto the outdoor unit 1 of the air conditioner, the radiator 14 is arranged in the fan wheel compartment 21, and the electronic control component 16 is arranged in the compressor compartment 22. During the operation of the outdoor unit 1, the fan wheel 27 in the fan wheel compartment 21 rotates to generate negative pressure. Under the action of negative pressure, airflow is generated in the fan wheel compartment 21 and blows forward. As the airflow blows forward, it passes over the radiator 14, thereby carrying away some of the heat on the radiator 14. At the same time, the airflow in the compressor compartment 22 enters the electronic control box 11 through the air inlet 113, blows over the electronic control component 16 in the electronic control box 11 and exchanges heat, passes through the ventilation hole 121 and partition plate 12 into the second chamber 112, then blows over the radiator 14 and flows out from the air outlet 114 into the fan wheel compartment 21. Subsequently, the airflow blown out by the electronic control component 10 and the airflow in the fan wheel compartment 21 are blown forward out of the fan wheel compartment 21 under the action of the fan wheel 27.

[0050] It is understood that the heat exchange efficiency of the radiator 14 is relatively high. The heat generated during the operation of the electronic control component 10 can be dissipated at a relatively fast rate through the radiator 14. The airflow speed in the fan wheel chamber 21 is relatively fast and the air volume is relatively large. By placing the radiator 14 in the fan wheel chamber 21, the airflow in the fan wheel chamber 21 blows over the radiator 14 to dissipate heat, which can improve the heat dissipation efficiency of the electronic control component 10.

[0051] When the outdoor unit 1 of the air conditioner is working in rainy or snowy weather, the fan wheel 27 will throw the rainwater hitting the fan wheel 27 out in the left and right directions during the rotation process. As those skilled in the art will understand, the fan wheel 27 is connected to the shaft at the rear, there is a gap between the fan wheel 27 and the rear wall of the fan wheel compartment 21, and the fan wheel 27 pushes the airflow forward. In this way, the rainwater will be thrown out from the fan wheel 27 towards the left front and right front, so that some of the rainwater passes through the radiator 14 and is thrown to the front end of the partition plate 12.

[0052] In this embodiment, by providing a wind deflector 13, the wind deflector 13 blocks the ventilation hole 121 formed in the upper region of at least the front end of the partition plate 12. In this way, the wind deflector 13 can block rainwater from being thrown into the first cavity 111 from the ventilation hole 121 in the upper region of the front end of the partition plate 12, and prevent rainwater from being thrown onto the electronic control board 15 and electronic control component 16 located on the upper side of the first cavity 111, thereby improving the waterproof performance of the electronic control component 10.

[0053] According to the first aspect of the present invention, after the electronic control component 10 is assembled onto the outdoor unit 1 of the air conditioner, the radiator 14 is arranged in the fan wheel compartment 21, which can improve the heat dissipation efficiency of the electronic control component 10. By blocking the ventilation hole 121 formed in at least the upper front part of the partition plate 12 by the baffle plate 13, the baffle plate 13 can block the rainwater thrown by the fan wheel 27, thereby improving the waterproof performance of the electronic control component 10 and improving the reliability of the electronic control component 10 during operation.

[0054] In some embodiments of this utility model, such as Figures 7-9 As shown, in the top-to-bottom direction, the wind deflector 13 extends at least partially in a direction away from the second cavity 112. That is, either a portion of the wind deflector 13 extends in a direction away from the second cavity 112, or the entire wind deflector 13 extends in a direction away from the second cavity 112.

[0055] In this way, after the airflow and rainwater impact the wind deflector 13 through the ventilation hole 121, the airflow and rainwater can flow downward under the guidance of the wind deflector 13. This can further improve the waterproof performance of the electronic control component 10. In the downward direction, the distance between the wind deflector 13 and the partition plate 12 increases, and the flow space between the wind deflector 13 and the partition plate 12 increases, which can allow the airflow to carry the rainwater downward and discharge quickly.

[0056] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the partition plate 12 located on the upper side of the wind deflector 13 extends in a straight line in the vertical direction. The wind deflector 13 includes a first plate segment and a second plate segment connected sequentially from top to bottom. The first plate segment extends in the vertical direction along an arc protruding toward the first cavity 111. The second plate segment extends in the vertical direction at an angle toward the first cavity 111. The upper end of the first plate segment is connected to the wind deflector 13, and the lower end of the first plate segment is connected to the second plate segment.

[0057] The partition plate 12, located above the wind deflector 13, extends vertically in a straight line. This facilitates positioning of the upper end of the partition plate 12 during assembly. Furthermore, when airflow hits the vertical partition plate 12, water is more easily drawn downwards by gravity. The first plate segment extends along an arc protruding towards the first cavity 111. On one hand, the lower part of the first plate segment extends at an angle away from the second cavity 112, providing sufficient airflow space between the wind deflector 13 and the partition plate 12, allowing airflow to exit from this space at a faster rate. On the other hand, this makes the airflow smoother and reduces noise during the operation of the outdoor unit 1. The second plate segment extends at an angle towards the first cavity 111. The second plate segment blocks airflow vertically and further increases the airflow space between the second plate segment and the partition plate 12 horizontally.

[0058] During the product design process, parameters such as the size or relative angle of the first and second plate segments can be adjusted to meet more product design needs.

[0059] In some embodiments of this utility model, the distance between the partition plate 12 located on the upper side of the baffle plate 13 and the radiator 14 in the left-right direction is 0.5mm-2mm. For example, in the left-right direction, the distance between the first plate segment and the radiator 14 can be 0.5mm, 0.6mm, 0.9mm, 1.3mm, 1.7mm, 1.9mm or 2mm. The radiator 14 includes: heat dissipation fins and heat dissipation base plate. The heat dissipation base plate is connected to the electronic control board 15. The heat dissipation fins are disposed on the heat dissipation base plate. In the left-right direction, the partition plate 12 located on the upper side of the baffle plate 13 is opposite to the heat dissipation base plate. The distance between the partition plate 12 located on the upper side of the baffle plate 13 and the radiator 14 is the same as the distance between the partition plate 12 located on the upper side of the baffle plate 13 and the heat dissipation base plate. In this way, the internal components of the first cavity 111 can be arranged more compactly, and the probability of the partition plate 12 and the radiator 14 knocking each other during the operation of the outdoor unit 1 of the air conditioner is low. During the product design process, the distance between the partition plate 12 located on the upper side of the wind deflector 13 and the radiator 14 can be adjusted to meet more product design needs.

[0060] In some embodiments of this utility model, the distance between the second plate segment and the heat sink 14 in the left-right direction is 3mm-20mm. For example, the distance between the second plate segment and the heat sink 14 in the left-right direction can be 3mm, 6mm, 10mm, 17mm, 19mm, or 20mm. This allows the space between the second plate segment and the partition plate 12 to meet the airflow rate requirements, and the baffle plate 13 will not encroach on too much space within the first cavity 111. During product design, the distance between the second plate segment and the heat sink 14 can be adjusted to meet more product design needs.

[0061] In some embodiments of this utility model, the ratio of the dimension from the front edge of the partition plate 12 to the rear edge of the windbreak plate 13 to the dimension of the partition plate 12 in the front-rear direction is 0.5-1. For example, the ratio of the dimension from the front edge of the partition plate 12 to the rear edge of the windbreak plate 13 to the dimension of the partition plate 12 in the front-rear direction can be 0.5, 0.6, 0.7, 0.8, 0.86, 0.9, or 1. When the front edge of the partition plate 12 is not flush with the front edge of the windbreak plate 13, the partition plate 12 between the front edges of the partition plate 12 and the front edges of the windbreak plate 13 forms a closed area, thereby ensuring that the shielding effect of the windbreak plate 13 meets the waterproof requirements of the electronic control component 10. During product design, the ratio of the dimension from the front edge of the partition plate 12 to the rear edge of the windbreak plate 13 to the dimension of the partition plate 12 can be adjusted to meet more product design needs.

[0062] In some embodiments of this utility model, the ratio of the dimension from the upper edge of the partition plate 12 to the lower edge of the wind baffle 13 to the height of the partition plate 12 in the vertical direction is 1 / 3 to 1 / 2. For example, the ratio of the dimension from the upper edge of the partition plate 12 to the lower edge of the wind baffle 13 to the height of the partition plate 12 in the vertical direction is 1 / 3, 5 / 12, 3 / 8, or 1 / 2. This allows the wind baffle 13 to provide sufficient shielding for the waterproofing of the electronic control component 10, and ensures that the airflow rate between the first cavity 111 and the second cavity 112 meets the heat dissipation requirements of the electronic control component 10. During product design, the ratio of the dimension from the upper edge of the partition plate 12 to the lower edge of the wind baffle 13 to the height of the partition plate 12 can be adjusted to meet more product design needs.

[0063] In some embodiments of this utility model, such as Figures 7-9 As shown, the partition plate 12 is also provided with a plurality of wind baffles 122 on one side of the first cavity 111. The wind baffles 122 block at least a portion of the ventilation hole 121. The wind baffles 122 are used to block the wind blown in by the ventilation hole 121. The lower end of the wind baffle plate 13 extends to the wind baffles 122.

[0064] During the operation of the outdoor unit 1, when the fan wheel 27 throws rainwater into the ventilation hole 121, the wind deflector 122 can block the rainwater. Under the action of gravity, the rainwater flows downward along the wind deflector 122, thereby preventing the rainwater from being thrown onto the electrical control components 16 and the electrical control board 15. This further improves the waterproof performance of the electrical control components 10, and thus further improves the reliability of the outdoor unit 1 during operation. It should be noted that the wind deflector 122 does not block the ventilation hole 121; airflow can bypass the wind deflector 122 and flow within the ventilation hole 121.

[0065] In some embodiments of this utility model, such as Figures 7-9 As shown, both the ventilation hole 121 and the wind baffle 122 extend along the first direction, and the two ends of the wind baffle 122 are respectively connected to the edges of the two ends of the ventilation hole 121 in the first direction.

[0066] The wind deflector 122 and the partition plate 12 are spaced apart in the left and right directions, that is, the wind deflector 122 and the ventilation hole 121 are spaced apart on both sides of the vertical direction in the first direction. Thus, on the one hand, the wind deflector 122 has a good shielding effect on the ventilation hole 121, which can further improve the waterproof performance of the electronic control component 10. On the other hand, in the circumferential direction of the ventilation hole 121, the portion of the wind deflector 122 that is spaced apart from the partition plate 12 accounts for a large proportion, which can improve the flow efficiency of airflow in and out of the ventilation hole 121, thereby further improving the heat dissipation efficiency of the electronic control component 10.

[0067] In some embodiments of this utility model, such as Figures 7-9As shown, the ventilation hole 121 extends vertically, and in the downward direction, part of the wind deflector 122 extends obliquely away from the second cavity 112.

[0068] Therefore, on the one hand, the gap between the wind deflector 122 and the partition plate 12 can be increased, thereby further improving the efficiency of airflow through the ventilation hole 121 and improving the heat dissipation efficiency of the electronic control component 10. On the other hand, when the impeller 27 throws rainwater onto the wind deflector 122, the water deflector can guide the rainwater, causing it to flow downwards along the wind deflector 122 and then be discharged from the first cavity 111, thereby further reducing the probability of rainwater contacting the electronic control component 16 and the electronic control board 15 on the upper side of the first cavity 111.

[0069] In some embodiments of this utility model, the distance between the top wall of the second cavity 112 and the heat sink 14 in the vertical direction is 10mm-30mm. For example, the distance between the top wall of the second cavity 112 and the heat sink 14 in the vertical direction can be 10mm, 15mm, 17mm, 18mm, 20mm, 27mm, 29mm or 30mm. This allows sufficient gas flow space between the top wall of the second cavity 112 and the heat sink 14, enabling the heat sink 14 to fully contact the airflow, thereby ensuring that the heat dissipation efficiency of the heat sink 14 meets the requirements of the electronic control component 10.

[0070] In some embodiments of this utility model, such as Figures 7-9 As shown, the electrical control box 11 includes an upper box 115 and a lower box 116, which are interlocked to define a first cavity 111 and a second cavity 112. This allows for easier assembly of components within the electrical control box 11 by first attaching them to either the upper or lower box 115, minimizing obstruction. Then, the upper and lower boxes are interlocked, positioning the electrical control unit 16 within the first cavity 111 and the heat sink 14 within the second cavity 112. This reduces the difficulty of assembling the electrical control assembly 10. Furthermore, during product design, the structure and dimensions of the upper and lower boxes 115 and 116 can be adjusted to meet various product design needs.

[0071] In some embodiments of this utility model, such as Figure 4 , Figure 6 and Figure 7 As shown, the bottom of the second cavity 112 is open, and ventilation openings communicating with the second cavity 112 are formed on both the front and rear sides of the lower box 116.

[0072] The bottom of the second cavity 112 is open, and ventilation openings are formed on the front and rear sides, which can increase the ventilation volume of the radiator 14 and allow airflow to pass through the radiator 14 more quickly, thereby improving the heat exchange efficiency between the airflow and the radiator 14.

[0073] The following is for reference. Figures 1-10 The outdoor unit 1 of an air conditioner according to a second aspect embodiment of the present invention is described.

[0074] like Figures 1-3 As shown, the outdoor unit 1 of the air conditioner according to the second aspect of the present invention includes: a housing 20 and the electronic control component 10 according to the first aspect of the present invention.

[0075] Specifically, the housing 20 has a fan wheel compartment 21 and a compressor compartment 22 arranged on the left and right sides. The fan wheel compartment 21 is equipped with a fan wheel 27. The first chamber 111 is located in the compressor compartment 22, and the second chamber 112 is located in the fan wheel compartment 21. The front of the electrical control box 11 is opposite to the fan wheel 27 in the left and right direction.

[0076] The enclosure 20 includes an enclosure body 24, a front panel 25, and an upper cover 26. The front and upper sides of the enclosure body 24 are open, and the front panel 25 and the upper cover 26 cover the front and upper sides of the enclosure body 24, respectively.

[0077] During the operation of the outdoor unit 1 of the air conditioner, the fan wheel 27 in the fan wheel compartment 21 rotates to generate negative pressure. Under the action of negative pressure, airflow is generated in the fan wheel compartment 21 and blows forward. As the airflow blows forward, it passes over the radiator 14, thereby carrying away some of the heat on the radiator 14. At the same time, the airflow in the compressor compartment 22 enters the electrical control box 11 through the air inlet 113. In the electrical control box 11, it blows over the electrical control component 16 and exchanges heat. It then passes through the ventilation hole 121, passes through the partition plate 12, and enters the second chamber 112. Then it blows over the radiator 14 and flows out from the air outlet 114 into the fan wheel compartment 21. Subsequently, the airflow blown out by the electrical control component 10 and the airflow in the fan wheel compartment 21 are blown forward out of the fan wheel compartment 21 under the action of the fan wheel 27.

[0078] The second cavity 112 is located in the wind turbine chamber 21, that is, the radiator 14 is located in the wind turbine chamber 21, which can improve the heat dissipation efficiency of the radiator 14. The first cavity 111 is provided with a baffle plate 13, which can improve the waterproof performance of the electronic control component 10.

[0079] According to the second aspect of the present invention, the reliability of the outdoor unit 1 of the air conditioner can be improved by providing the electronic control component 10 according to the first aspect of the present invention during operation.

[0080] In some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the upper edge of the partition plate 23 is recessed downward to form a mounting groove. The electrical control assembly 10 is disposed in the mounting groove. The rear surface of the electrical control box 11 and the rear wall of the mounting groove cooperate to define a communication port, which connects the wind turbine compartment 21 and the compressor compartment 22.

[0081] After the electronic control component 10 is assembled into the mounting slot, the radiator 14 is located in the fan wheel compartment 21, and the electronic control component 16 is located in the compressor compartment 22. During the operation of the outdoor unit 1 of the air conditioner, the airflow entering from the rear side of the fan wheel compartment 21 can blow over the radiator 14 and take away some of the heat on the radiator 14. At the same time, some airflow can blow over the rear surface of the electronic control box 11 and blow into the compressor compartment 22 through the communication port.

[0082] Therefore, the assembly structure of the electronic control component 10 on the partition plate 23 is relatively simple, which can reduce the difficulty of product design and production. The mounting groove is located on the upper edge of the partition plate 23, and the electronic control component 10 is also located on the upper part of the housing 20, that is, the electronic control component 10 is located above the impeller 27. In this way, when the airflow generated by the impeller 27 flows upward toward the electronic control component 10, some water will fall downward under the action of gravity, thereby reducing the water content in the airflow blown into the compressor compartment 22 from the connection port during rainy or snowy weather, and further improving the reliability of the outdoor unit 1 of the air conditioner during operation.

[0083] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, at least a portion of the partition 23 extends obliquely toward the compressor compartment 22 in the front-to-back direction. That is, either a portion of the partition 23 may extend obliquely toward the compressor compartment 22, or the entire partition 23 may extend obliquely toward the compressor compartment 22.

[0084] Therefore, in the front-back direction, part of the outer wall of the first cavity 111 can be opposite to the rear air intake area of ​​the wind turbine compartment 21 through the connecting port. Part of the airflow blown in from the rear air intake area of ​​the wind turbine compartment 21 can be directly blown to part of the outer wall of the first cavity 111. The airflow passes through the rear end face of the electronic control box 11 at a faster speed and the amount of air flowing into the compressor compartment 22 is larger. In this way, the heat dissipation efficiency of the electronic control component 10 can be further improved.

[0085] An air conditioner according to a third aspect of the present invention includes: the outdoor unit 1 of the air conditioner according to the second aspect of the present invention.
