Description

Technical Field

[0001] This invention relates to the field of waterproof cabinet technology, specifically to a waterproof cabinet structure and a cabinet. Background Technology

[0002] As a crucial component of electrical equipment, server racks serve to house and protect the internal electronic components. Existing server racks for electrical equipment generally include a frame, mounting panels on the frame, and an openable door. Typically, server racks designed for outdoor environments have high waterproof and rainproof requirements to prevent rainwater from entering and damaging the internal electronic components. However, because the door needs to open and close, gaps can easily form between the door and the frame, allowing rainwater to enter the rack. To address this, existing technologies usually incorporate waterproof strips on the frame or door. When the door is closed, the waterproof strip deforms under pressure, sealing the gap and preventing water ingress. However, when the door is opened, the waterproof strip returns to its original shape. If water is present at this point, it can drip from the strip and impact protruding components on the inside of the door, such as the back panel of a display screen, splashing onto the internal electronic components and causing damage. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a waterproof cabinet structure and cabinet. This waterproof cabinet structure can improve the situation where water drips from the waterproof strip and splashes into the electronic components inside the cabinet, causing damage to the electronic components.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Technical Solution 1: A waterproof cabinet structure, the cabinet including a cabinet body and a cabinet door, the cabinet door being adapted to cooperate with the door frame of the cabinet body to open or close the cabinet body, the door frame of the cabinet body being provided with a waterproof rubber strip around its perimeter; the inner surface of the cabinet door being adapted to tightly adhere to and press against the waterproof rubber strip when closed to seal the gap between the cabinet door and the cabinet body; a water-receiving groove protruding from the inner surface of the cabinet door is provided near its upper edge on the inner side of the cabinet door, and the water-receiving groove is lower in height than the waterproof rubber strip located at the upper edge of the door frame of the cabinet body; the water-receiving groove opens upward and extends to both sides of the cabinet door, and is adapted to receive liquid dripping from the waterproof rubber strip located above it when the cabinet door is opened and within a preset angle range.

[0006] Technical Solution 2 based on Technical Solution 1: The side wall of the water receiving groove away from the inner surface of the cabinet door, when the cabinet door is opened and within the preset angle range, is located on the side of the outer edge of the waterproof strip away from the cabinet door on the projection plane perpendicular to the vertical direction.

[0007] Technical Solution 3 based on Technical Solution 2: The height of the side wall of the water receiving tank away from the inner surface of the cabinet door is configured to be higher than the splash height of the liquid impacting the bottom of the water receiving tank.

[0008] Technical Solution 4 based on Technical Solution 3: Two first water inlet channels are provided on the inner side of the cabinet door. The top ends of the two first water inlet channels are respectively connected to the two ends of the water receiving channel and extend vertically to the bottom of the cabinet door. The opening directions of the two first water inlet channels are respectively pointing to the outer side of the cabinet door and the side corresponding to its position.

[0009] Technical Solution 5 based on Technical Solution 4: The cabinet door includes a door panel and a reinforcing rib. The reinforcing rib is fixedly installed on the door panel and is suitable for improving the structural strength of the cabinet door; the water receiving groove and the first water inlet groove are provided on the reinforcing rib.

[0010] Technical solution six, based on any one of technical solutions one to five: the two ends of the water receiving trough extend to the position near the side edge of the cabinet door; the cabinet body has a water guiding trough with an upward opening at the upper edge of its door frame that extends to the side edge near the door frame, and the waterproof adhesive strip is installed on the outer side wall of the water guiding trough.

[0011] Technical solution seven based on technical solution six: The cabinet is provided with a second water channel on each side edge of its door frame. The tops of the two second water channels are respectively connected to the two ends of the water channel and extend vertically to the bottom of the door frame. The opening directions of the two second water channels are respectively pointing to the outside of the side of the door frame corresponding to their positions.

[0012] Technical solution eight based on technical solution seven: The cabinet is provided with a first flange protruding from the inner side wall of the water guide channel above the water guide channel, and the first flange extends to both sides of the cabinet to adapt to the length of the water guide channel.

[0013] Technical solution nine based on technical solution eight: The upper edge of the cabinet door is higher than the waterproof strip located at the upper edge of the door frame, and a second flange protruding inward is provided. The second flange extends to both sides of the cabinet door to match the length of the water guide groove.

[0014] In addition, the present invention also provides technical solution ten: a cabinet, which includes a cabinet body and a cabinet door, characterized in that the cabinet body and the cabinet door adopt the cabinet waterproof structure as described in any one of technical solutions one to nine.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] Technical Solution 1 provides a waterproof cabinet structure. This structure features waterproof strips around the door frame. When the door is closed, the inner surface of the door presses against and compresses the waterproof strip, causing it to deform and seal the gap between the door and the strip. This seal prevents rainwater from entering the cabinet. Simultaneously, a water-receiving groove is located inside the door, below the waterproof strip at the top edge of the door frame and protruding from the inner surface of the door. The groove's opening faces upwards. When the door is opened to a certain angle, such as when the lock is just released, the door will open slightly outwards. Furthermore, the pressure on the waterproof sealant strip is removed from the cabinet door, creating a gap between the strip and the door. Water accumulated on the sealant strip will drip off, and the dripping liquid will be caught by the dripping trough below. This prevents the liquid from hitting the protruding parts inside the cabinet door and splashing onto the electronic components inside the cabinet. The trough extends to both sides of the cabinet door, allowing it to drain away when a large amount of liquid is collected. Because the trough is long enough, the draining liquid can avoid the protruding parts inside the cabinet door or the electronic components located in the middle of the cabinet, further reducing the impact of liquid splashing on the electronic components inside the cabinet.

[0017] In technical solution two, the preset angle range of the cabinet door opening is limited, or in other words, the width of the water receiving trough and its relationship with this angle range are limited. This angle range should ensure that the side wall of the water receiving trough away from the inner surface of the cabinet door is always inside the outer edge of the waterproof sealant. In this way, when the cabinet door is opened within the preset angle range, the liquid dripping from the waterproof sealant can be caught by the water receiving trough. At the same time, when the cabinet door is opened to a position outside the preset angle range, although the waterproof sealant may still drip liquid, because the cabinet door is already opened to a position far away from the door frame, the liquid dripping from the waterproof sealant will not be able to hit the protruding parts on the inner side of the cabinet door, or even if it hits the protruding parts, the splashed liquid will not be able to reach the electronic components inside the cabinet.

[0018] In technical solution three, the height of the side wall of the water receiving trough away from the inner surface of the cabinet door is higher than the liquid splash height. The liquid splash height is related to the type of liquid and the distance between the bottom of the water receiving trough and the outer edge of the waterproof sealant. By limiting the height of the water receiving trough wall, it can be ensured that the liquid will not splash out of the water receiving trough after dripping, thereby preventing the liquid from splashing into the electronic components inside the cabinet.

[0019] In technical solution four, two first water inlet channels are installed on the cabinet door. The first water inlet channels can guide the water in the water inlet channel to the bottom of the cabinet, thereby reducing the impact on electronic components in higher positions inside the cabinet.

[0020] In technical solution five, the cabinet door includes a door panel and reinforcing ribs. The reinforcing ribs can improve the overall structural strength of the cabinet door, and the thickness of the cabinet door can be thinner, thereby reducing the manufacturing cost of the cabinet door. At the same time, the water receiving groove and the first water inlet groove are set by using the reinforcing ribs, that is, the reinforcing ribs are directly processed into components with groove-shaped structures. This eliminates the need to process the door panel, greatly reducing the difficulty of setting the water receiving groove and the first water inlet groove. Meanwhile, the reinforcing ribs can also improve the overall structural strength of the cabinet door.

[0021] In technical solution six, the two ends of the water receiving groove extend to the side edge of the cabinet door. The increased length of the water receiving groove can catch as much liquid dripping from the waterproof sealant as possible, reducing liquid splashing. In addition, a water guide groove is also installed on the door frame. When the water volume is large, the water guide groove can quickly drain the excess water, reducing water accumulation at the waterproof sealant. At the same time, when the waterproof sealant above the water receiving groove is damaged or aged, causing the seal to fail, the water receiving groove can also catch liquid that seeps into the cabinet body and drain the collected liquid from both ends of the water receiving groove.

[0022] In technical solution seven, the two ends of the water guide channel are connected to the second water inlet channel, which allows rainwater to flow along the second water inlet channel to the bottom of the cabinet, preventing rainwater from overflowing from the water guide channel and then entering the cabinet through the waterproof rubber strip on the side.

[0023] In technical solution eight, a first flange is installed on the cabinet. The first flange can bounce some of the rainwater away when it falls, thereby reducing the amount of water entering the water guide channel and the waterproof strip.

[0024] In technical solution nine, a second flange is provided on the upper edge of the cabinet door. The second flange can cooperate with the first flange to form a more comprehensive shield above the water guide channel, reducing the impact on the water guide channel and the waterproof strip, and improving the service life of the waterproof strip.

[0025] Technical solution ten provides a cabinet, which includes a cabinet body and a cabinet door, and adopts the above-mentioned cabinet waterproof structure, which can improve the problem of water dripping from the waterproof strip and splashing onto the electronic components inside the cabinet when the door is opened.

[0042] Example

[0043] This invention provides a cabinet, which mainly includes a cabinet body 1 and a cabinet door 2. In practical applications, corresponding electronic devices can be installed on the cabinet to achieve corresponding functions according to different needs. For example, when the cabinet is applied to a converter, power components for rectification and inversion, as well as corresponding reactors, heat sinks, transformers, controllers, and other devices can be installed inside the cabinet. In this case, the cabinet is used to install these electronic devices, and the electronic devices inside the cabinet body 1 can be inspected and maintained by opening and closing the cabinet door 2.

[0044] Reference Figure 1The cabinet 1 is roughly rectangular in shape, with four vertical main columns. Horizontal beams are installed between these columns, forming a cabinet frame with high structural strength and stability. Panels are installed on the left, right, rear, bottom, and top sides of this frame, sealing the cabinet 1 from all sides, leaving an opening on the front. The cabinet door 2 is hinged to the cabinet 1 and can be opened or closed by rotating it. The area around the front opening of the cabinet 1 forms a door frame, and the cabinet door 2 cooperates with the door frame to open or close the cabinet 1.

[0045] The cabinet provided in this embodiment adopts the waterproof cabinet structure proposed in this invention. The waterproof cabinet structure will be described in detail below.

[0046] Reference Figure 1 , Figure 2 and Figure 3 A waterproof rubber strip 3 is provided around the door frame of cabinet 1, and the inner surface of cabinet door 2 is adapted to tightly adhere to and press the waterproof rubber strip 3 when closed to seal the gap between cabinet door 2 and cabinet 1. The waterproof rubber strip 3 can be a ring-shaped rubber ring that can be fixed around the doorway and serves to waterproof the opening of cabinet 1. Since the door frame is rectangular, the waterproof rubber strip 3 also has four sides, each of which is parallel to the edge of the door frame it is located on.

[0047] The structure of the waterproof strip 3 can be referred to Figure 4 , Figure 5 and Figure 6 The waterproof sealing strip 3 has a fixing part 31 for fixing to the door frame. The fixing part 31 can be fixedly connected to the door frame of the cabinet 1 by various methods such as pasting, clamping, and pressing. At the same time, the front side of the waterproof sealing strip 3 is a deformable deformation part 32. When the cabinet door 2 is closed, the inner surface of the cabinet door 2 will be tightly pressed against the deformation part 32 on the front side of the waterproof sealing strip 3, forcing the deformation part 32 to deform, so that the waterproof sealing strip 3 is tightly attached to the inner surface of the cabinet door 2, thereby sealing the gap between the cabinet door 2 and the cabinet 1 and preventing rainwater, dust and other external factors from entering the cabinet. The deformation part 32 can be a hollow structure. The hollow structure gives the waterproof sealing strip 3 better deformation ability. At the same time, since the waterproof sealing strip 3 is made of elastic materials such as rubber, it can automatically recover its deformation when the cabinet door 2 is opened. In this embodiment, a protruding strip 33 extending parallel to the edge of the door frame is provided on the front side of the deformable part 32 of the waterproof strip 3. The protruding strip 33 protrudes from the surface of the deformable part 32 and is provided on both the inner and outer sides of the waterproof strip 3. When the cabinet door 2 is closed, the edge of the protruding strip 33 and the front end of the deformable part 32 will be in close contact with the inner surface of the cabinet door 2. At this time, the protruding strips 33 on the upper and lower sides cooperate with the front end of the deformable part 32 to achieve a triple waterproofing effect.

[0048] Reference Figure 3 , Figure 6 , Figure 7 and Figure 8 A water-receiving groove 4 protruding from the inner surface of the cabinet door 2 is provided on the inner side of the cabinet door 2 near its upper edge, and the water-receiving groove 4 is lower in height than the waterproof adhesive strip 3 located at the upper edge of the door frame of the cabinet body 1; the water-receiving groove 4 opens upward and extends to both sides of the cabinet door 2, and is adapted to receive the liquid dripping from the waterproof adhesive strip 3 located above it when the cabinet door 2 is opened and within a preset angle range.

[0049] Specifically, refer to Figure 7 It is easy to see that the cabinet door 2 of the electrical cabinet must also have components such as monitors installed on it, and these components will protrude from the inner surface of the cabinet door 2. When the cabinet door 2 is opened, the water accumulated on the waterproof sealant 3 will drip onto these protruding components and then splash onto the electronic components inside the cabinet, thereby causing damage to the electronic components.

[0050] Therefore, in this embodiment, a water-receiving groove 4 is provided along the upper edge of the cabinet door 2. The water-receiving groove 4 protrudes from the inner surface of the cabinet door 2, with its opening facing upwards and extending to the left and right sides of the cabinet door 2. The water-receiving groove 4 has a certain width, and has a groove wall on the side away from the inner surface of the cabinet door 2, which is the first groove wall 41. The water-receiving groove 4 is located above the protruding part on the inner side of the cabinet door 2, without obstruction between it and the waterproof sealing strip 3. Therefore, when the cabinet door 2 is just opened, the waterproof sealing strip 3 returns to its original shape, and water drips from the waterproof sealing strip 3 into the water-receiving groove 4. The first groove wall 41 of the water-receiving groove 4 will block the splashing of liquid, thereby improving the situation where liquid splashes onto the electronic components inside the cabinet 1.

[0051] In general, when cabinet door 2 is closed, the inner surface of cabinet door 2 will tightly adhere to and press against the waterproof sealant strip 3, causing the waterproof sealant strip 3 to deform to a certain extent. This seals the gap between cabinet door 2 and the waterproof sealant strip 3, thus preventing rainwater from entering the interior of cabinet body 1. Simultaneously, a water-receiving groove 4 is installed inside cabinet door 2. The water-receiving groove 4 is lower than the waterproof sealant strip 3 at the top edge of the door frame and protrudes from the inner surface of cabinet door 2. The opening of the water-receiving groove 4 faces upward. When cabinet door 2 is opened to a certain angle, for example, when the lock on cabinet door 2 is just released, cabinet door 2 will open slightly outward at a small angle, and the pressure on the waterproof sealant strip 3 will be removed. A gap is formed between the waterproof sealing strip 3 and the cabinet door 2. Water accumulated on the waterproof sealing strip 3 will drip from the waterproof sealing strip 3. The dripping liquid will be caught by the water receiving groove 4 below, thus preventing the liquid from dripping down and hitting the protruding parts on the inside of the cabinet door 2 and splashing onto the electronic components inside the cabinet 1. Furthermore, the water receiving groove 4 extends to both sides of the cabinet door 2. When the water receiving groove 4 receives a large amount of dripping liquid, this liquid can flow away from both ends of the water receiving groove 4. And because the water receiving groove 4 has a certain length, this flowing liquid can avoid the protruding parts on the inside of the cabinet door 2 or avoid the electronic components located in the middle part of the left and right direction inside the cabinet 1, further reducing the impact of liquid splashing on the electronic components inside the cabinet 1.

[0052] The water receiving trough 4, located on the side of its wall away from the inner surface of the cabinet door 2, lies on the outer edge of the waterproof adhesive strip 3, away from the cabinet door 2, on a projection plane perpendicular to the vertical direction when the cabinet door 2 is open and within the preset angle range. The height of the side of its wall away from the inner surface of the cabinet door 2 is configured to be higher than the splash height of liquid impacting the bottom of the water receiving trough 4.

[0053] Specifically, the width of the water collection trough 4 needs to be adapted to a preset angle range. This preset angle range varies slightly depending on the size of the cabinet door 2, but is generally within the range of 1° to 8°. When the cabinet door 2 is opened and within this range, the pressure of the inner surface of the cabinet door 2 on the waterproof sealant 3 is removed, and the water accumulated on the waterproof sealant 3 will drip down. At this time, since the first wall 41 of the water collection trough 4 is still located inside the outer edge of the waterproof sealant 3, the dripping liquid will still fall into the water collection trough 4, thereby preventing the liquid from splashing onto the cabinet body 1. As one implementation method, the width of the water collection trough 4 can be made greater than the protrusion of the protruding part on the inner surface of the cabinet door 2, thereby ensuring that the accumulated water will definitely drip into the water collection trough 4. However, as a better option, the water collection trough 4 does not need to be set too wide, because after the cabinet door 2 is opened, even if the accumulated water drips onto the protruding part on the inner side of the cabinet door 2, the kinetic energy of the splashed liquid may not be sufficient to contact the electronic components inside the cabinet body 1. At this time, the harm caused by the dripping and splashing of water is greatly reduced.

[0054] By limiting the preset angle range of the cabinet door 2 when it is opened, or by limiting the width of the water receiving sink 4 and its relationship with the preset angle range, this angle range should ensure that the side wall of the water receiving sink 4 away from the inner surface of the cabinet door 2 is always inside the outer edge of the waterproof strip 3. In this way, when the cabinet door 2 is opened within the preset angle range, the liquid dripping from the waterproof strip 3 can be caught by the water receiving sink 4. At the same time, when the cabinet door 2 is opened to a position other than the preset angle range, although the waterproof strip 3 may still drip liquid, since the cabinet door 2 has been opened to a position relatively far from the door frame, the liquid dripping from the waterproof strip 3 can no longer hit the protruding parts on the inner side of the cabinet door 2, or even if it hits the protruding parts, the splashed liquid cannot reach the electronic components inside the cabinet 1.

[0055] Furthermore, the height of the first wall 41 of the water receiving trough 4 is also adapted to the distance between the bottom of the water receiving trough 4 and the waterproof sealant 3. The density of rainwater is known. Based on the distance from the bottom of the water receiving trough 4 to the edge of the liquid dripping from the waterproof sealant 3, the kinetic energy of the rainwater droplets can be known. The height and angle of the rainwater splash can be determined based on this kinetic energy. Based on these conditions, the height of the first wall 41 can be designed to meet the requirement of preventing water splashes to the outside of the water receiving trough 4.

[0056] In addition, two first water inlet channels 5 are provided on the inner side of the cabinet door 2. The top ends of the two first water inlet channels 5 are respectively connected to the two ends of the water receiving channel 4 and extend vertically to the bottom of the cabinet door 2. The opening directions of the two first water inlet channels 5 are respectively pointing to the outer side of the cabinet door 2 and the side corresponding to its position.

[0057] Specifically, refer to Figure 3 , Figure 7 and Figure 8 There are two first water inlet channels 5, both extending vertically with their openings facing outwards from the cabinet. One first water inlet channel 5 is located on the left side of the cabinet door 2, with its upper end connected to the left end of the water receiving channel 4. The other first water inlet channel 5 is located on the right side of the cabinet door 2, with its upper end connected to the right end of the water receiving channel 4. The lower ends of the first water inlet channels 5 extend to the bottom of the cabinet door 2. When the water receiving channel 4 receives accumulated water, the water will flow from the first water inlet channels 5 to the bottom of the cabinet, reducing the impact on electronic components located at higher positions inside the cabinet.

[0058] Meanwhile, when the waterproof sealing strip 3 is damaged, water may leak even without opening the door. In this case, the water collection tank 4 can catch the leaked liquid and drain it from both ends of the water collection tank 4 to the first water inlet tank 5. A drainage channel can be installed at the bottom of the cabinet 1, for example, with a one-way valve or simply a drain outlet, to drain excess water away. Furthermore, a dehumidifier can be installed inside the cabinet. Since the electronic components inside the cabinet generate a lot of heat during operation, this heat will evaporate any accumulated water, which will then be drained away by the dehumidifier.

[0059] In this embodiment, refer to Figure 6 , Figure 7 and Figure 8 The cabinet door 2 includes a door panel 6 and a reinforcing rib 7. The reinforcing rib 7 is fixedly installed on the door panel 6 and is adapted to improve the structural strength of the cabinet door 2. The water receiving groove 4 and the first water inlet groove 5 are provided on the reinforcing rib 7. The reinforcing rib 7 can improve the overall structural strength of the cabinet door 2, and the thickness of the cabinet door 2 can be thinner, thereby reducing the manufacturing cost of the cabinet door 2. At the same time, by using the reinforcing rib 7 to set the water receiving groove 4 and the first water inlet groove 5, that is, by directly processing the reinforcing rib 7 into a component with a groove structure, there is no need to process the door panel 6. The difficulty of setting the water receiving groove 4 and the first water inlet groove 5 is greatly reduced. At the same time, the reinforcing rib 7 can also play its role in improving the overall structural strength of the cabinet door 2. The reinforcing rib 7 is a metal profile, which generally has a groove structure. However, usually, the opening of the groove structure on the reinforcing rib 7 will face the cabinet door 2 or the cabinet body 1, rather than facing outward. This invention creatively utilizes the original reinforcing rib 7 on the cabinet and changes the opening of the groove on the reinforcing rib 7 to face the outside of the cabinet, thereby playing the role of receiving and guiding water.

[0060] In addition, refer to Figure 3 and Figure 6 The two ends of the water receiving trough 4 extend to the cabinet door 2 near the side edge; the cabinet body 1 has a water guide trough 8 with an upward opening at the upper edge of its door frame and extending to the side edge of the door frame, and the waterproof strip 3 is installed on the outer side wall of the water guide trough 8.

[0061] The water-receiving groove 4 extends to both ends of the cabinet door 2 near the side edge. This increased length allows it to better collect liquid dripping from the waterproof sealant strip 3, minimizing splashing. The wall of the water-guiding groove 8 furthest from the cabinet body 1 forms a second groove wall 81, where the fixing part 31 of the waterproof sealant strip 3 is inserted for fixation. When the water volume is large, the water-guiding groove 8 can quickly drain excess water, reducing water accumulation at the waterproof sealant strip 3. With less water accumulation at the waterproof sealant strip 3, less rainwater drips when the cabinet door 2 is opened, improving splashing and allowing the water-receiving groove 4 to better collect the dripping rainwater.

[0062] Reference Figure 3 The cabinet 1 has a second water-guiding channel 9 on each side edge of its door frame. The tops of the two second water-guiding channels 9 are connected to the two ends of the water-guiding channel 8 and extend vertically to the bottom of the door frame. The openings of the two second water-guiding channels 9 point to the outer side of the door frame corresponding to their positions. The structure and function of the second water-guiding channel 9 are similar to those of the first water-guiding channel 5, except that it is connected to the water-guiding channel 8. The two ends of the water-guiding channel 8 are connected to the second water-guiding channels 9, allowing rainwater to flow along the second water-guiding channels 9 to the bottom of the cabinet 1, preventing rainwater from overflowing from the water-guiding channel 8 and then entering the cabinet 1 through the waterproof sealing strip 3 on the side.

[0063] Reference Figure 3 and Figure 6 The cabinet body 1 has a first flange 10 protruding from the inner side wall of the water guide channel 8 above the water guide channel 8. The first flange 10 extends to both sides of the cabinet body 1 to match the length of the water guide channel 8. At the same time, the upper edge of the cabinet door 2 is higher than the waterproof strip 3 located at the upper edge of the door frame, and has a second flange 11 protruding inward. The second flange 11 extends to both sides of the cabinet door 2 to match the length of the water guide channel 8.

[0064] Specifically, refer to Figure 6 In this embodiment, the water inlet position at the cabinet door 2 is above the first flange 10. The first flange 10 is formed by extending forward a certain distance from the top plate of the cabinet body 1, which can block rainwater and prevent rainwater from directly pouring into the water guide trough 8. Below the first flange 10, a second flange 11 is also provided on the door panel 6 of the cabinet door 2. The second flange 11 can be formed by fixing a metal profile to the inside of the door panel 6. The second flange 11 overlaps with both the first flange 10 and the water channel 8 on the projection plane perpendicular to the vertical direction. The second flange 11 is located between the first flange 10 and the water channel 8. After being blocked by the first flange 10, rainwater falls to the position of the second flange 11, is blocked again by the second flange 11, and then falls into the position of the water channel 8. This reduces the kinetic energy of the rainwater and prevents the rainwater from directly impacting the water channel 8 and the waterproof strip 3. The water channel 8 can effectively drain the rainwater from both sides, and the waterproof strip 3 is not easily damaged by impact.

[0065] This invention provides a cabinet, which includes a cabinet body 1 and a cabinet door 2. Electronic devices can be installed inside the cabinet body 1 to realize corresponding electrical functions.
