[0002] In the field of heat pump air conditioners, the electrical control box, as the core control unit, directly affects the air conditioner's performance and lifespan due to its operational stability. Heat dissipation performance and waterproofing capabilities are crucial prerequisites for ensuring the long-term reliable operation of the electronic components inside the control box. Currently, the industry generally adopts an independent, enclosed structure design for the control box, with specially planned internal heat dissipation channels. The heat dissipation method is primarily unidirectional ventilation, using unidirectional airflow to dissipate the heat generated by the electronic components.

[0003] As a key component of the air duct of the electrical control box, the baffle plate is usually placed at the air inlet and outlet of the air duct, and plays a dual core role: on the one hand, it needs to effectively isolate the condensate generated inside the unit and the rainwater that may intrude, block the contact path between moisture and electronic components, and avoid short circuits and other malfunctions; on the other hand, it needs to guide the airflow to flow smoothly along the preset air duct, ensure that the heat dissipation airflow fully covers the heat-generating components, maintain the internal temperature at a safe threshold, and ensure the stable operation of electronic components.

[0004] However, the water-blocking performance of existing water-blocking plate structures needs further improvement. Utility Model Content

[0022] 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.

[0023] The following is for reference. Figures 1-6 A housing assembly 100 according to a first aspect embodiment of the present invention is described. The housing assembly 100 of this embodiment is used in an air conditioner 1000.

[0024] like Figure 1 As shown, the housing assembly 100 according to the first aspect of the present invention includes: a housing 10, a water receiving tray 20, and a water baffle 30.

[0025] Specifically, the water receiving tray 20 is disposed inside the housing 10, and the water receiving tray 20 divides the space inside the housing 10 into a first cavity 101 and a second cavity 102 arranged at intervals. The first cavity 101 is located on the upper side of the second cavity 102. The water receiving tray 20 defines a water receiving groove 21. The water receiving tray 20 forms a vent 22 that penetrates the bottom wall of the water receiving groove 21 in the vertical direction. The vent 22 is configured to communicate with the air outlet of the electrical control box assembly 300 arranged in the second cavity 102. A water baffle 30 is provided at the position of the vent 22. The water baffle 30 has an opening 301. The vent 22 communicates with the first cavity 101 through the opening 301. In the vertical direction, the distance between the lower edge of the opening 301 and the bottom wall of the water receiving groove 21 is greater than or equal to 10 mm.

[0026] Reference Figure 1As shown, the housing 10 may include a base assembly 15, a top cover assembly 16, a top ring frame 14, a middle ring frame 13, and corner posts 12. The base assembly 15 is located at the bottom of the housing 10, and the top cover assembly 16 and the top ring frame 14 are located at the top of the housing 10. The top ring frame 14 is rectangular, and the top cover assembly 16 is connected to the top ring frame 14 and located inside the top ring frame 14. Multiple corner posts 12 extend vertically in a columnar shape and are located at the corners of the housing 10. The upper end of each corner post 12 is connected to the top ring frame 14, and the lower end is connected to the base assembly 15. The housing 10 also includes a middle post 11, which extends vertically and connects the top ring frame 14 and the base assembly 15. The middle post 11 is located between two adjacent corner posts 12. The middle ring frame 13 is rectangular and is connected to both the multiple corner posts 12 and the multiple middle posts 11.

[0027] like Figure 1 As shown, the drip tray 20 is arranged between the top ring frame 14 and the base assembly 15, and the periphery of the drip tray 20 is fixedly connected to the middle ring frame 13. The drip tray 20 includes a tray body and a baffle 24 arranged along the edge of the tray body and extending upward. The tray body and the baffle 24 cooperate to form a drip groove 21 with an open top. The upper side of the drip tray 20 is a first cavity 101, which is suitable for arranging the condenser assembly of the air conditioner 1000. The condensate from the condenser assembly can drip into the drip tray 20. The drip tray 20 also has water passage holes 23 that penetrate the drip tray 20 in the vertical direction. There can be multiple water passage holes 23, which are arranged around the periphery of the drip tray 20 and spaced apart along the circumference of the drip tray 20. The condensate and / or rainwater in the drip tray 20 can be discharged downward into the second cavity 102 through the multiple water passage holes 23. The lower side of the water receiving tray 20 is the second chamber 102, which is suitable for arranging equipment such as compressors, refrigerant pipelines, gas-liquid separators and electrical control box assembly 300.

[0028] like Figure 1 As shown, a vent 22 is formed on the bottom wall of the water receiving groove 21 of the water receiving tray 20. The vent 22 can extend into a long rectangular hole along the width direction of the water receiving tray 20. A water-blocking member 30 is installed at the position of the vent 22. The water-blocking member 30 can be sealed to the periphery of the vent 22. For example, a sealing member can be provided between the water-blocking member 30 and the periphery of the vent 22 to seal the gap between the water-blocking member 30 and the periphery of the vent 22. Alternatively, the water-blocking member 30 can be welded to the periphery of the vent 22 to improve the reliability of the connection and sealing performance between the water-blocking member 30 and the water receiving tray 20.

[0029] It should be noted that the specific shape of the water-blocking component 30 is not specifically limited in this embodiment, as long as it can cover the ventilation opening 22 and form an opening 301. For example, the water-blocking component 30 can be a rectangular box shape, or it can be an upwardly convex arc-shaped plate shape.

[0030] The water baffle 30 has an opening 301 formed on it, and the number of openings 301 can be one or more. The vent 22 on the water receiving tray 20 is connected to the first cavity 101 through the opening 301. That is to say, the electrical control cavity of the electrical control box assembly 300 is connected to the first cavity 101 in sequence through the air outlet of the electrical control box assembly 300, the vent 22 on the water receiving tray 20, and the opening 301 on the water baffle 30. When the fan assembly 200 of the air conditioner 1000 is running, a negative pressure is formed in the first cavity 101 under the driving action of the fan assembly 200, so that the hot air in the electrical control cavity of the electrical control box assembly 300 can enter the first cavity 101 in sequence through the air outlet, the vent 22, and the opening 301, and then be driven by the fan assembly 200 to be discharged to the outside of the housing assembly 100. This achieves heat dissipation for the electronic control components within the electronic control cavity of the electronic control box assembly 300, ensuring the heat dissipation performance of the electronic control box assembly 300 and guaranteeing the working performance of the electronic control components within the electronic control box assembly 300.

[0031] Furthermore, such as Figure 4 As shown, in the vertical direction, the distance L between the lower edge of the opening 301 and the bottom wall of the water receiving tank 21 is greater than or equal to 10mm. For example, the distance L between the lower edge of the opening 301 and the bottom wall of the water receiving tank 21 can be 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm or 32mm.

[0032] According to the embodiment of the present invention, the housing assembly 100, by making the distance L between the opening 301 and the bottom wall of the water receiving tank 21 greater than or equal to 10mm, can effectively isolate rainwater and condensate in the water receiving pan 20. Even in heavy rain, it can block rainwater and effectively prevent rainwater and condensate from entering the electrical control box assembly 300 from the opening 301. At the same time, it ensures that the electrical control box assembly 300 can normally achieve heat dissipation through the opening 301, thus ensuring the ventilation and heat dissipation efficiency of the electrical control box assembly 300.

[0033] In some embodiments of this utility model, such as Figure 4As shown, in the vertical direction, the distance L between the lower edge of the opening 301 and the bottom wall of the water receiving tank 21 is less than or equal to 20 mm. For example, in the vertical direction, the distance L between the lower edge of the opening 301 and the bottom wall of the water receiving tank 21 can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm. Therefore, the distance between the opening 301 and the bottom wall of the water receiving tank 21 can be limited to a suitable range, reducing the height of the water-blocking component 30 in the vertical direction, reducing the amount of material used in the water-blocking component 30, and lowering costs.

[0034] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the water-blocking member 30 includes a side plate portion 31 and a top plate portion 32. The side plate portion 31 is connected to the periphery of the top plate portion 32 and extends downward. The side plate portion 31 and the top plate portion 32 form a box shape with the lower side open. An opening 301 is formed on the side plate portion 31. The lower end of the side plate portion 31 is provided with a flange 33. The flange 33 extends in the horizontal plane in a direction away from the vent 22. The water-blocking member 30 is connected to the periphery of the vent 22 by the flange 33.

[0035] In some examples, the cross-section of the side plate portion 31 parallel to the horizontal plane can be circular, elliptical, square, or polygonal, and the side plate portion 31 and the top plate portion 32 together define a downwardly opening cavity 302. Furthermore, the shape of the side plate portion 31 can be adapted to the shape of the vent 22.

[0036] In this embodiment, an opening 301 is formed on the side plate portion 31, and the opening 301 extends through the side plate portion 31 along its wall thickness direction. This further reduces the probability of rainwater or condensate entering the vent 22 through the opening 301, improving the waterproofing effect of the water-blocking component 30. Simultaneously, by providing a flange 33 at the lower end of the side plate portion 31 and connecting the flange 33 to the periphery of the vent 22, this embodiment increases the contact area between the water-blocking component 30 and the water-receiving tray 20, improving the reliability and stability of the connection between them. It also enhances the overall structural strength of the water-blocking component 30 and extends its service life.

[0037] In some embodiments of this utility model, such as Figure 4As shown, the flange 33 is arranged on the lower side of the drip tray 20. When assembling the drip tray 20 and the water baffle 30, the top plate portion 32 and the side plate portion 31 of the water baffle 30 can be inserted into the upper side of the drip tray 20 through the vent 22 from bottom to top, so that the upper surface of the flange 33 abuts against the lower surface of the drip tray 20 in the vertical direction. During the use of the air conditioner 1000, when rainwater or condensate in the drip tray 20 flows down along the gap between the inner wall of the vent 22 and the outer surface of the side plate portion 31, the flange 33 can guide the rainwater and condensate to flow horizontally away from the vent 22, thus preventing rainwater and condensate from directly entering the electrical control box assembly 300 from the vent 22 position, further improving the waterproof effect of the water baffle 30. In addition, by placing the flange 33 on the lower side of the water receiving tray 20, a portion of the water-blocking member 30 can be located on the upper side of the water receiving tray 20, and the other portion can be located on the lower side of the water receiving tray 20, thereby further improving the connection stability between the water-blocking member 30 and the water receiving tray 20.

[0038] In some embodiments of this utility model, such as Figure 4 As shown, the width W of the flange 33 is greater than or equal to 8 mm in the direction from the center of the vent 22 toward the periphery. For example, the width W of the flange 33 in the direction from the center of the vent 22 toward the periphery can be 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm or more. By making the width W of the flange 33 greater than or equal to 8 mm, sufficient overlap length and contact area between the flange 33 and the drip tray 20 can be ensured, improving the stability and reliability of the connection between the flange 33 and the drip tray 20.

[0039] In some specific examples, such as Figure 4 and Figure 6 As shown, the side plate portion 31 is rectangular and annular, and in the width direction of the side plate portion 31 (for example...) Figure 4 In the left-right direction shown, the width W of the two flanges 33 on both sides of the side plate portion 31 in the width direction is greater than or equal to 8 mm, and in the length direction of the side plate portion 31, for example... Figure 6 In the front-to-back direction shown, the width W of the flanges 33 at both ends in the length direction of the side plate portion 31 is greater than or equal to 8 mm.

[0040] In some embodiments of this utility model, the flange 33 extends in a ring shape along the circumference of the side plate portion 31. This further enhances the overall structural strength of the water-blocking member 30, further reduces the probability of rainwater and condensate entering the electrical control box assembly 300, and further improves the reliability of the connection between the water-blocking member 30 and the water receiving tray 20.

[0041] In some embodiments of this utility model, such as Figure 4 As shown, the flange 33 includes multiple extension segments 331, which are arranged circumferentially at intervals on the side plate portion 31. For example, the number of extension segments 331 can be two, three, four, five, six, seven, eight, or more. This reduces the processing difficulty of the water-blocking component 30 and improves processing efficiency.

[0042] like Figure 6 As shown, the side plate portion 31 is a rectangular ring, and the flange 33 includes four extension segments 331. The four extension segments 331 are respectively arranged and connected to the four side edges of the lower end of the side plate portion 31, and the two ends of the four extension segments 331 are respectively flush with the two ends of each corresponding side edge on the side plate portion 31.

[0043] In some embodiments of this utility model, the water-blocking member 30 and the water-receiving tray 20 can be welded together. This ensures the reliability of the connection between the water-blocking member 30 and the water-receiving tray 20 and improves the sealing performance at the connection point. For example, the water-blocking member 30 can be welded to the water-receiving tray 20 via a flange 33, or the water-blocking member 30 can be welded to the water-receiving tray 20 via a side plate portion 31.

[0044] In some embodiments of this utility model, such as Figure 6 As shown, the water-blocking component 30 and the water-receiving tray 20 are connected by fasteners. This allows for convenient installation and disassembly of the water-blocking component 30 and the water-receiving tray 20 while ensuring the reliability of the connection, thus improving installation and disassembly efficiency and reducing maintenance costs.

[0045] For example, the flange 33 of the water-blocking component 30 can be provided with a first fixing hole 332, and the water receiving tray 20 can be provided with a second fixing hole. There can be multiple first fixing holes 332 and multiple second fixing holes. The multiple first fixing holes 332 and multiple second fixing holes correspond one-to-one. The first fixing hole 332 and the corresponding second fixing hole are directly opposite each other in the vertical direction. Fasteners pass through the first fixing holes 332 and the second fixing holes to achieve a fastening connection between the flange 33 and the water receiving tray 20, thereby fixing the water-blocking component 30 to the water receiving tray 20.

[0046] Furthermore, a sealing element is provided between the water-blocking member 30 and the water-receiving tray 20. The sealing element extends in a ring shape along the circumference of the water-blocking member 30 and seals against the upper surface of the flange 33 and the lower surface of the water-receiving tray 20.

[0047] In some embodiments of this utility model, such as Figure 6As shown, there are multiple openings 301, which are arranged at intervals along the circumference of the side plate portion 31. For example, the number of openings 301 can be two, three, four, five, six, eight, ten, fifteen, or more. This increases the total ventilation area on the water baffle 30 and improves the heat dissipation efficiency of the electrical control box assembly 300.

[0048] In some embodiments of this utility model, such as Figure 6 As shown, the side plate portion 31 has a rectangular horizontal cross-section. The side plate portion 31 includes two first vertical plates 311 and two second vertical plates 312. The two first vertical plates 311 extend along the length of the water-blocking member 30 and are spaced apart in the width direction of the water-blocking member 30. The two second vertical plates 312 are arranged at the ends of both ends of the water-blocking member 30 in the length direction and connect between the two first vertical plates 311. Multiple openings 301 are respectively provided on the two first vertical plates 311. The total area of ​​the openings 301 on the first vertical plates 311 is greater than or equal to 50% and less than or equal to 80% of the area of ​​the first vertical plate 311. For example, the total area of ​​the openings 301 on the first vertical plates 311 can be 50%, 55%, 60%, 65%, 70%, 75%, or 80% of the area of ​​the first vertical plate 311. In this embodiment, by ensuring that the total area of ​​the openings 301 on the first vertical plate 311 is greater than or equal to 50% and less than or equal to 80% of the area of ​​the first vertical plate 311, sufficient ventilation area can be ensured on the first vertical plate 311, thereby increasing the ventilation volume and ensuring the heat dissipation effect on the electrical control box assembly 300. It can also prevent the area of ​​a single opening 301 on the first vertical plate 311 from being too large, reducing the risk of external debris entering the electrical control box assembly 300 through the opening 301.

[0049] In some embodiments of this utility model, the water-blocking component 30 and the water-receiving tray 20 can be integrally formed. For example, the water-blocking component 30 and the water-receiving tray 20 can be integrally formed by a stretching process.

The fan assembly 200 is disposed on the top of the housing assembly 100 and is used to drive the air in the first cavity 101 to be discharged from the first cavity 101. The electrical control box assembly 300 is disposed in a second cavity 102 and has an electrical control cavity and an air inlet and an air outlet communicating with the electrical control cavity. The electrical control cavity is connected to a vent 22 through the air outlet.

[0051] like Figure 1As shown, the fan assembly 200 may include multiple fans arranged side-by-side on the top of the housing assembly 100, with the top cover assembly 16 of the housing 10 covering the upper side of the fan assembly 200. The fan axes of the fan assembly 200 extend vertically, and the fan exhaust ports face upwards. The electrical control box assembly 300 is arranged within the second cavity 102. The air inlet of the electrical control box assembly 300 can communicate with the external environment, and the air outlet of the electrical control box assembly 300 communicates with the first cavity 101 through an opening 301 on the water baffle 30.

[0052] According to the embodiment of the present utility model, the air conditioner 1000, by setting the housing assembly 100 of the first aspect embodiment, makes the distance L between the opening 301 on the water baffle 30 and the bottom wall of the water receiving tray 21 greater than or equal to 10mm, which can effectively isolate rainwater and condensate in the water receiving tray 20. Even in heavy rain, it can block rainwater and effectively prevent rainwater and condensate from entering the electrical control box assembly 300 from the opening 301. At the same time, it ensures that the electrical control box assembly 300 can normally achieve heat dissipation through the opening 301, ensuring the ventilation and heat dissipation efficiency of the electrical control box assembly 300, thereby improving the overall performance of the air conditioner 1000.

[0053] The following will refer to Figures 1-6 This invention describes an air conditioner 1000 according to a specific embodiment of the present invention.

[0054] Reference Figure 1 The air conditioner 1000 includes: a housing assembly 100, a fan assembly 200, an electrical control box assembly 300, a condenser assembly, refrigerant piping, a compressor, a gas-liquid separator, and a liquid receiver.

[0055] Specifically, such as Figure 1 As shown, the housing assembly 100 includes a housing 10, a water receiving tray 20, and a water baffle 30. The housing 10 includes a top cover assembly 16, a base assembly 15, a central column 11, corner columns 12, a central ring frame 13, and a top ring frame 14. The water receiving tray 20 is disposed inside the housing 10, dividing the housing 10 into an upper and lower independent first cavity 101 and a second cavity 102. The first cavity 101 is arranged above the second cavity 102. The fan assembly 200 is disposed on the top of the housing assembly 100 and communicates with the first cavity 101. The condenser assembly is disposed inside the first cavity 101 and is located at the edge of the first cavity 101, extending circumferentially along the first cavity 101. The central column 11 and the corner columns 12 are arranged around the periphery of the water receiving tray 20.

[0056] like Figure 2 and Figure 5As shown, the water receiving tray 20 has multiple water passage holes 23 arranged at intervals along the circumference of the water receiving tray 20, and the water receiving tray 20 has an upwardly extending baffle 24. The water receiving tray 20 also has a vent 22, which is a long rectangular hole with its length along the front-back direction and its width along the left-right direction.

[0057] like Figure 3 and Figure 6 As shown, the water-blocking member 30 is a rectangular box shape with an open lower side. The shape of the lower opening of the water-blocking member 30 matches that of the ventilation opening 22. The lower opening of the water-blocking member 30 is connected to a flange 33 extending outward in the horizontal direction, and the width of the flange 33 is greater than or equal to 8mm. Multiple openings 301 are provided on the side plate portion 31 of the water-blocking member 30. The multiple openings 301 are arranged at intervals along the circumference of the water-blocking member 30. The openings 301 are formed on the first vertical plates 311 on the left and right sides of the water-blocking member 30, and are elongated rectangular holes extending in the front-back direction. The multiple openings 301 are used to guide airflow and enhance the ventilation and heat dissipation efficiency inside the electrical control box assembly 300. Of course, the openings 301 can also be circular holes.

[0058] The water-blocking component 30 is installed at the ventilation opening 22. The upper surface of the flange 33 abuts against the lower surface of the water receiving tray 20 through a sealing component. The water-blocking component 30 can be fastened to the water receiving tray 20 through the flange 33, or the water-blocking component 30 and the water receiving tray 20 can be welded together.

[0059] In the vertical direction, the distance L between the lowest point of the opening 301 on the water-blocking component 30 and the bottom wall of the water-receiving groove 21 of the water-receiving tray 20 is ≥10mm, which effectively isolates rainwater and condensate, and can effectively block rainwater even in heavy rain. At the same time, since the flange 33 of the water-blocking component 30 is located on the lower side of the water-receiving tray 20, the condensate in the water-receiving groove 21 can be guided away in time through the gap between the water-receiving tray 20 and the water-blocking component 30, preventing it from directly flowing into the electrical control box assembly 300.

[0060] Furthermore, the water baffle 30 is cleverly positioned below the fan of the fan assembly 200. The operation of the fan assembly 200 drives the airflow in the air duct. The fan assembly 200 can not only enhance the heat exchange of the condenser, but also promote the heat exchange inside the electrical control box assembly 300, ensuring that the heat dissipation effect of the electrical control box assembly 300 is improved.

[0061] The water-blocking component 30 in the above embodiments can effectively prevent rainwater or condensate from flowing back into the electrical control box assembly 300, achieving good heat dissipation and water blocking effects.
