Description

Technical Field

[0001] This utility model belongs to the field of air conditioning design technology, specifically relating to a vertical electrical box, an outdoor unit of an air conditioner, and an air conditioner. Background Technology

[0002] As a crucial component of central air conditioning systems, outdoor air conditioning units (such as air conditioner outdoor units) are typically exposed to the open air, enduring complex climatic conditions such as rain, humidity, and dust over extended periods. The electrical box, as the core control component of the outdoor unit, contains various precision circuits and electronic components. Water ingress can lead to short circuits, component damage, and even systemic malfunctions, severely impacting the stable operation and lifespan of the air conditioning system. Therefore, the waterproof and sealing performance of the electrical box is of paramount importance.

[0003] However, existing sealing technologies for air conditioner outdoor unit electrical boxes still present numerous problems in practical applications. Traditional sealing designs typically employ simple sealants or sealing strips for waterproofing. While these can prevent moisture ingress to some extent, their sealing effectiveness often fails to guarantee performance under complex operating conditions (such as heavy rainfall, high temperature, and high humidity environments). Furthermore, some high-end air conditioner outdoor units utilize multi-layer sealing structures and high-quality sealing materials. Although these improve sealing performance to some extent, their manufacturing costs increase significantly, leading to a rise in the overall price of the equipment and limiting its market promotion and application.

[0004] In addition, the after-sales maintenance cost of existing sealed electrical boxes is also high. Once water enters the electrical box due to seal failure, maintenance personnel need to disassemble, clean and reseal the electrical box, and may even need to replace the seal or the entire electrical box. This not only increases the user's maintenance cost, but may also lead to extended equipment downtime and affect normal use. Utility Model Content

[0005] Therefore, this utility model provides a vertical electrical box, an outdoor air conditioner unit, and an air conditioner, which can overcome the shortcomings of related electrical box technologies that cannot simultaneously achieve waterproof performance and cost control.

[0006] To address the aforementioned problems, this utility model provides a vertical appliance box, comprising a box body and a cover. The box body includes a main body, which includes a vertical wall and side walls surrounding the outer periphery of the vertical wall. An opening is formed on the side of the side wall opposite to the vertical wall. The cover is used to seal the opening. The cover includes a cover body, which includes a vertical wall parallel to the vertical wall and side walls surrounding the outer periphery of the vertical wall. Taking the orientation of the vertical appliance box in use as a reference, both the box opening and the vertical wall extend along a vertical plane. The side wall at the top of the main body is the top wall, and the side walls at the left and right ends of the top wall are the side walls. At least the top surface of the top wall is provided with a first rain guard. The top wall is a lid wall, and the side walls at the left and right ends of the lid top wall are lid side walls. At least the top surface of the lid top wall is provided with a second rainproof member. The first rainproof member has a first plate and a second plate that are parallel and spaced apart and both extend toward the lid side. The first plate and the second plate are connected as one unit through a first connecting part. The first rainproof member is sealed to the lid top wall through the first connecting part. The second rainproof member has a third plate that extends toward the box body side. The second rainproof member is sealed to the lid top wall through a second connecting part. The third plate, the first plate, and the lid top wall are arranged in parallel. The first plate, the third plate, and the second plate are staggered from bottom to top. The opening of the first gap formed by the first plate and the third plate is located on the side of the second gap formed by the third plate and the second plate that is closer to the box body.

[0007] In some implementations, the vertical width of the first gap is smaller than the vertical width of the second gap.

[0008] In some embodiments, the first connecting portion includes a fourth plate parallel to the box wall, the fourth plate being connected to the first plate and located on the side of the first plate near the box top wall, the free end of the top wall having an upward-facing bent plate parallel to the fourth plate, the bent plate abutting against the side of the fourth plate away from the box wall, forming a first pressure relief drainage channel between the upper side of the bent plate and the lower side of the first plate.

[0009] In some embodiments, the top surface of the box top wall abuts against and fits against the bottom surface of the lid top wall.

[0010] In some embodiments, the top surface of the box top wall has a second pressure relief drainage channel extending laterally along its width to the box side wall.

[0011] In some embodiments, a fifth plate parallel to the fourth plate is formed on the free end face of the second plate near the lid, and mounting holes are formed on the fifth plate.

[0012] In some embodiments, the first connecting portion further includes a sixth plate and a seventh plate, the sixth plate being parallel to the first plate and connected to the lower end of the fourth plate, the seventh plate being parallel to the box wall and connected between the sixth plate and the second plate, the first rainproof member being fixedly connected to the box top wall via the sixth plate, and the first rainproof member being formed by bending a piece of sheet metal; and / or, the second connecting portion includes an eighth plate and a ninth plate, the eighth plate being located between the third plate and the ninth plate, and the second rainproof member being fixedly connected to the cover top wall via the ninth plate, and the second rainproof member being formed by bending a piece of sheet metal.

[0013] In some embodiments, a first connecting plate is provided on the outer side wall of each of the two box side walls, and a second connecting plate is provided on the outer side wall of each of the two cover side walls. The first connecting plate and the second connecting plate, which are in corresponding positions, are in contact with each other and can be detachably connected together.

[0014] In some embodiments, the left and right ends of the first rain shield extend along the outer wall surface of the box sidewall to the box edge wall; and / or, the left and right ends of the second rain shield extend along the outer wall surface of the cover sidewall to the cover edge wall.

[0015] In some embodiments, a reinforcing plate is formed on the inner sidewall surface of the free end of the box sidewall, the reinforcing plate being formed by bending the box sidewall.

[0016] This utility model also provides an air conditioner outdoor unit, including the above-mentioned vertical electrical box.

[0017] This utility model also provides an air conditioner, including the above-mentioned outdoor unit.

[0018] The vertical electrical box, air conditioner outdoor unit, and air conditioner provided by this utility model have the following beneficial effects: The first sealing element at the top of the box and the second sealing element at the top of the cover form a first gap and a second gap with opposite opening directions when the box and cover are assembled and in use. The opening of the first gap is within the shielding space formed by the second plate. The second gap and the first gap are set sequentially along the intrusion direction of rainwater in the intrusion path, which can achieve double shielding against rainwater intrusion. Without setting waterproof sealing strips, the waterproof performance of the vertical electrical box is improved. Since waterproof sealing strips and other easily consumable sealing materials are not set, the cost of the electrical box is reduced. The fourth plate and the bent plate are pressed together to form the first sealed and waterproof structure, which can further reduce the probability of rainwater entering the area where the first sealed and waterproof structure is located through the aforementioned second gap and first gap. At the same time, the first pressure relief drainage channel formed between the upper side of the bent plate and the lower side of the first plate can discharge the rainwater that enters through the first gap in time. Without the need to install a sealing strip, the probability of rainwater entering the electrical box through the aforementioned first sealed and waterproof structure is further reduced. In this invention, a second gap, a first gap, a first sealing and waterproofing structure, and a second sealing and waterproofing structure are sequentially arranged in the direction of rainwater intrusion, thereby forming a multi-layer physical seal against rainwater. This greatly reduces the probability of rainwater intruding into the electrical box and improves the waterproof performance of the vertical electrical box. Since the electrical box in this invention does not require easily consumable sealing materials such as auxiliary sealing strips, the waterproofing of the vertical electrical box can be achieved solely by the structural cooperation between the first and second sealing elements on the electrical box and the box body and cover body after assembly. This also reduces design and maintenance costs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

[0025] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0026] See also Figures 1 to 10 As shown, according to an embodiment of the present invention, a vertical electrical appliance box is provided, including a box body (not labeled in the figure) and a cover (not labeled in the figure). The box body includes a box main body 1, which includes a box upright wall 11 and a box side wall (not labeled in the figure) arranged around the outer peripheral edge of the box upright wall 11. The box side wall forms a box opening (not labeled in the figure) on the side opposite to the box upright wall 11. The cover is used to seal the box opening. The cover includes a cover main body 2, which includes a cover upright wall 21 arranged parallel to and opposite to the box upright wall 11 and a cover side wall (not labeled in the figure) arranged around the outer peripheral edge of the cover upright wall 21. The orientation of the vertical electrical appliance box in its use state is used as a reference (e.g., Figure 1The state shown is the usage state of the vertical electrical box. The box opening and the box wall 11 both extend along a vertical plane. The box side wall at the top of the box body 1 is the box top wall 121, and the box side walls at the left and right ends of the box top wall 121 are the box side walls 122. At least the top surface of the box top wall 121 is provided with a first rainproof member 3. The cover side wall at the top of the cover body 2 is the cover top wall 221, and the cover side walls at the left and right ends of the cover top wall 221 are the cover side walls 222. At least the top surface of the cover top wall 221 is provided with a second rainproof member 4. The first rainproof member 3 has a first plate 31 and a second plate 32 that are parallel and spaced apart and both extend toward the box cover. The first plate 31 and the second plate 32 are connected as one unit via a first connecting part (not labeled in the figure). The first rainproof member 3 is sealed to the top wall 121 of the box via the first connecting part. The second rainproof member 4 has a third plate 41 extending toward one side of the box body. The second rainproof member 4 is sealed to the top wall 221 of the lid via the second connecting part (not indicated in the figure). The third plate 41, the first plate 31 and the top wall 121 of the box are arranged in parallel. The first plate 31, the third plate 41 and the second plate 32 are staggered from bottom to top. The opening of the first gap formed by the first plate 31 and the third plate 41 is located on the side of the second gap formed by the third plate 41 and the second plate 32 closer to the box body. It can be understood that the opening of the first gap is located within the shielding space formed by the second plate 32. The first gap and the second gap are arranged in parallel intervals.

[0027] In this technical solution, the first rain-proof component 3 at the top of the box and the second rain-proof component 4 at the top of the cover form a first gap and a second gap with opposite opening directions when the box and cover are assembled and in use. The opening of the first gap is located within the shielding space formed by the second plate 32. The second gap and the first gap are sequentially set along the intrusion direction of the rainwater intrusion path, which can achieve double shielding against rainwater intrusion. Without setting waterproof sealing strips, the waterproof performance of the vertical electrical box is improved. Since waterproof sealing strips and other easily damaged sealing materials are not set, the cost of the electrical box is reduced.

[0028] It is understandable that the vertical widths of the aforementioned first and second gaps should be designed to be relatively small to facilitate the assembly of the box and the cover, in order to further reduce the probability of rainwater intrusion. In some embodiments, the vertical width of the first gap is smaller than the vertical width of the second gap. The aforementioned vertical widths are based on the orientation of the vertical electrical box in use. In this technical solution, the vertical width of the second gap is greater than the vertical width of the first gap, that is, the gap on the outside of the electrical box is greater than the gap on the inside, which can further ensure smooth alignment of the box and the cover during assembly.

[0029] In some embodiments, the first connecting portion includes a fourth plate 33 parallel to the box wall 11. The fourth plate 33 is connected to the first plate 31 and is located on the side of the first plate 31 near the box top wall 121. The free end of the top wall 221 has an upward-facing bent plate 2211 parallel to the fourth plate 33. The bent plate 2211 abuts against the side of the fourth plate 33 away from the box wall 11. A first pressure relief drainage channel 30 is formed between the upper side of the bent plate 2211 and the lower side of the first plate 31. The aforementioned first pressure relief drainage channel 30 extends along the left and right width direction of the box body to discharge rainwater entering this position to the outside in a timely manner.

[0030] In this technical solution, the fourth plate 33 and the bent plate 2211 abut against each other to form a first sealed and waterproof structure, which can further reduce the probability of rainwater entering the area where the first sealed and waterproof structure is located through the aforementioned second gap and first gap. At the same time, the first pressure relief drainage channel 30 formed between the upper side of the bent plate 2211 and the lower side of the first plate 31 can discharge the rainwater that enters through the first gap in a timely manner. Without the need to set a sealing strip, the probability of entering the electrical box through the aforementioned first sealed and waterproof structure is further reduced.

[0031] In some embodiments, the top surface of the box top wall 121 abuts against the bottom surface of the cover top wall 221. Thus, downstream of the aforementioned first waterproof sealing structure, the box top wall 121 and the cover top wall 221 abut against each other to form a second waterproof sealing structure. This further prevents rainwater from outside the electrical box from entering the box through the top side, improving the waterproof performance of the vertical electrical box and ensuring electrical safety. It is understood that both the first and second waterproof sealing structures utilize the mating surfaces of two abutting components to form a seal.

[0032] It is worth emphasizing that in this utility model, a second gap, a first gap, a first sealing and waterproofing structure, and a second sealing and waterproofing structure are sequentially arranged in the direction of rainwater intrusion, thereby forming a multi-layer physical seal against rainwater. This greatly reduces the probability of rainwater intruding into the electrical box and improves the waterproof performance of the vertical electrical box. Since the electrical box in this utility model does not require easily consumable sealing materials such as auxiliary sealing strips, the waterproofing of the vertical electrical box can be achieved solely by the structural cooperation of the first rain-blocking component 3 and the second rain-blocking component 4 on the electrical box and the box body 1 and the cover body 2 after assembly. At the same time, it can reduce design and maintenance costs.

[0033] In some embodiments, the top surface of the box top wall 121 has a second pressure relief drainage channel 1211 extending from its width to the box side wall 122. In a specific embodiment, the second pressure relief drainage channel 1211 is integrally formed on the top surface of the box top wall 121 by rolling.

[0034] In some embodiments, a fifth plate 34 parallel to the fourth plate 33 is formed on the free end face of the second plate 32 near the lid, and the fifth plate 34 has mounting holes (not shown or indexed in the figure).

[0035] In this technical solution, a fifth plate 34 parallel to the fourth plate 33 is further provided on the side of the second plate 32 away from the first plate 31, and mounting holes are formed on the fifth plate 34. In specific applications, the vertical electrical box can be hoisted using the fifth plate 34, making the assembly method more flexible and conducive to improving the space utilization of the air conditioner outdoor unit.

[0036] In some embodiments, the first connecting portion further includes a sixth plate 35 and a seventh plate 36. The sixth plate 35 is parallel to the first plate 31 and connected to the lower end of the fourth plate 33. The seventh plate 36 is parallel to the box wall 11 and connected between the sixth plate 35 and the second plate 32. The first rainproof member 3 is fixedly connected to the box top wall 121 via the sixth plate 35. The first rainproof member 3 is formed by bending a piece of sheet metal. And / or, the second connecting portion includes an eighth plate 42 and a ninth plate 43. The eighth plate 42 is located between the third plate 41 and the ninth plate 43. The second rainproof member 4 is fixedly connected to the cover top wall 221 via the ninth plate 43. The second rainproof member 4 is formed by bending a piece of sheet metal. In a specific embodiment, the aforementioned sixth plate 35 and the box top wall 121, as well as the ninth plate 43 and the cover top wall 221, are fixedly connected by welding.

[0037] In this technical solution, both the first rainproof component 3 and the second rainproof component 4 are integrally formed by sheet metal bending, which can improve the rainproof and waterproof performance by simplifying the assembly process.

[0038] In some embodiments, a first connecting plate 1221 is provided on the outer side wall of each of the two box side walls 122, and a second connecting plate 2221 is provided on the outer side wall of each of the two cover side walls 222. The first connecting plate 1221 and the second connecting plate 2221 are in contact with each other and can be detachably connected together. When the first connecting plate 1221 and the second connecting plate 2221 are assembled and connected as a whole, the aforementioned bent plate 2211 will be tightly in contact with the side of the fourth plate 33 facing the cover. It should be noted that, since the electrical box is a vertically assembled electrical box, both the aforementioned first connecting plate 1221 and the second connecting plate 2221 extend in the vertical direction, and the gap formed by the connecting mating surfaces between the two also extends vertically. Under the action of its own weight, rainwater cannot stay in this gap for a long time. At the same time, since the electrical operating pressure inside the electrical box is higher than that outside, the probability of rainwater entering the electrical box through this gap is extremely low. Therefore, reliable sealing of the left and right side cover joints of the electrical box can be achieved simply by the contact and adhesion of the two connecting plates. There is no need to install easily worn sealing materials such as sealing strips in the gap, further reducing costs.

[0039] In some embodiments, the left and right ends of the first rain shield 3 extend along the outer wall surface of the box sidewall to the box sidewall 122; and / or, the left and right ends of the second rain shield 4 extend along the outer wall surface of the cover sidewall to the cover sidewall 222, thereby ensuring that the rainwater entering the aforementioned first pressure relief drainage channel 30 and second pressure relief drainage channel 1211 is discharged to the external environment in a timely and rapid manner.

[0040] In some embodiments, a reinforcing plate 1212 is formed on the inner sidewall of the free end of the box sidewall. The reinforcing plate 1212 is formed by bending the box sidewall. The aforementioned reinforcing plate 1212 can improve the deformation resistance of the box opening, thereby ensuring that the lid sidewall and the box sidewall can fit smoothly and tightly during assembly.

[0041] The side wall of the box located below the box body is the bottom wall 123. A waterproof cable connector 5 is provided on the bottom wall 123. The cables of the various electrical components inside the electrical box enter and exit the box body through this waterproof cable connector 5. Placing the waterproof cable connector 5 in the bottom area of ​​the box body can reduce the probability of rainwater entering the electrical box through the waterproof cable connector. It should be noted that the aforementioned waterproof design of the electrical box is also objectively a dustproof design.

[0042] It is worth emphasizing that this utility model only sets up two simple electrical box components, the box body and the cover body. When the two are assembled and in use, they form multiple waterproof and multiple pressure relief drainage channels, and are sealed layer by layer to achieve effective sealing against backflow. The structure is simple and does not require the use of easily consumable sealing materials, thus taking into account both waterproofing and cost control.

[0043] According to an embodiment of the present invention, an air conditioner outdoor unit is also provided, including the above-mentioned vertical electrical box.

[0044] According to an embodiment of the present invention, an air conditioner is also provided, including the above-described outdoor unit.

[0045] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model.
