[0005] Technical solution 2 based on technical solution 1: the inner groove wall of the guide groove is located within the inner edge of the drainage part on the projection plane perpendicular to the vertical direction.

[0006] Technical solution three based on technical solution two: the inner groove wall of the guide groove extends upward to the partition.

[0007] Technical solution four based on technical solution three: the guide groove has at least one liquid discharge end, and the liquid discharge end is used to discharge the liquid received by the guide groove to the outside of the guide groove.

[0008] Technical solution five based on technical solution four: the cabinet is provided with a liquid inlet groove connected to the discharge end of the guide groove, and the liquid inlet groove extends in a vertical direction and its lower end is open.

[0009] Technical solution six based on technical solution five: the liquid inlet groove extends downward to the bottom of the cabinet, and the closing component forms a liquid outlet gap between the bottom of the cabinet and the body of the cabinet.

[0010] Technical solution seven based on technical solution five: the outer groove walls of the guide groove and the liquid diversion groove are equipped with waterproof rubber strips, and the inner surface of the closing component corresponding to the position of the guide groove is tightly attached to and presses the waterproof rubber strip to close the gap between the guide groove, the liquid diversion groove and the inner surface of the closing component.

[0011] Technical solution eight based on technical solution seven: the drainage part is provided with multiple drainage holes at the left and right edge positions of the partition, and each drainage part includes multiple drainage holes arranged at intervals along the front and rear direction of the partition.

[0012] Technical solution nine based on technical solution eight: a plurality of guide grooves are provided on the left and right sides of the main body of the cabinet, and the guide grooves extend along the front and rear directions of the cabinet to correspond to the drainage range of the corresponding drainage part, the front and rear ends of the guide grooves are open to form the drainage ends, and the two drainage ends of each of the guide grooves are connected to the liquid inlet groove.

[0013] In addition, the present invention also provides technical solution ten: a energy storage inverter, which adopts a cabinet as described in any one of technical solutions one to nine, and a refrigerator is installed in the upper space of the cabinet, and the condensed water of the refrigerator is discharged from the upper space through the drain part on the partition.

[0014] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0015] Technical solution 1 provides a cabinet, the main body of which is divided into an upper space and a lower space by a horizontally arranged partition, wherein the upper space can be used to install a cold machine, and the lower space can be used to install electronic devices for realizing related functions. In order to ensure the normal operation of the electronic devices in the lower space, the lower space is also closed by a closing component on the surrounding side of the cabinet body; wherein, since the cold machine is installed in the upper space above the partition, it is necessary to drain the condensed water of the cold machine, and at the same time, the upper space is open and water may accumulate, so a drainage part that runs through from top to bottom is provided at a part of the edge of the partition, and the drainage part is located on the inner side of the closing component. With such a configuration, when the liquid in the upper space flows out from the drainage part, When the liquid flows out downward, the liquid will not flow to the outside of the sealing component, and will not be contaminated by dust on the outside of the sealing component to leave water marks; however, setting the drain part to be located on the inside of the sealing component will cause the liquid to be unable to be drained smoothly, and because the drain part is located on the inside of the sealing component, the liquid will also enter the inside of the cabinet body; therefore, in this solution, a guide groove is also provided on the cabinet body, and the guide groove corresponds to the position of the drain part and opens upward. The liquid flowing out of the drain part will fall into the guide groove, which can collect the liquid and guide the liquid to the outside of the cabinet body in a concentrated manner, thereby solving the problem of drainage difficulty after moving the drain part inward.

[0016] In the second technical solution, the inner groove wall of the guide groove is located outside the inner edge of the discharge portion to ensure that the liquid can be received by the guide groove when it flows out of the discharge portion.

[0017] In technical solution three, the inner groove wall of the guide groove extends upward to the partition, which can prevent the liquid flowing out of the drain part from entering the interior of the cabinet, and can guide the liquid to flow accurately into the guide groove after flowing out of the drain part.

[0018] In technical solution four, the guide groove is provided with a discharge end, through which the liquid received by the guide groove can be smoothly discharged to the outside of the guide groove.

[0019] In technical solution five, the cabinet is provided with a liquid inlet trough, which is connected to the discharge end of the guide trough, and the liquid received by the guide trough can be discharged downward along the liquid inlet trough.

[0020] In technical solution six, the liquid guide groove extends downward to the bottom of the cabinet, which can guide the liquid to the bottom of the cabinet, and then discharge it to the outside of the cabinet through the liquid outlet gap between the cabinet body and the closing component.

[0021] In technical solution seven, waterproof rubber strips are provided on the outer groove walls of the guide groove and the liquid guide groove. The closing component can seal the gap between the closing component and the cabinet body by making its inner surface close to the waterproof rubber strip, and can also prevent the liquid carried by the guide groove from entering the cabinet body.

[0022] In technical solution eight, multiple drainage parts are provided to improve the drainage capacity and avoid water accumulation in the upper space; at the same time, each drainage part includes multiple drainage holes arranged at intervals to avoid affecting the structural strength of the partition.

[0023] In technical solution nine, multiple guide grooves are provided to correspond to multiple drainage parts to ensure that the liquid flowing out of the drainage parts can be received and discharged.

[0024] Technical solution ten provides an energy storage inverter, which adopts the above-mentioned cabinet and is equipped with a refrigerator in the upper space of the cabinet. Through the cabinet, condensed water of the refrigerator can be discharged from the upper space through the drain part, and dirty water marks can be avoided from forming on the outer surface of the closed part of the cabinet.

[0043] Example 1

[0044] Reference Figure 1 Embodiment 1 of the present invention provides a cabinet, which mainly includes a main body 1 and a closing component 5, wherein the main body 1 is horizontally provided with a partition 2, and the main body 1 is divided into an upper space 3 and a lower space 4 by the partition 2, wherein the surrounding side of the lower space 4 is equipped with a closing component 5 for closing the lower space 4.

[0045] In practical applications, according to different needs, corresponding electronic devices can be installed on the cabinet to achieve corresponding functions. For example, when the cabinet is applied to the converter, power components for rectification and inversion, as well as corresponding reactors, radiators, transformers, controllers and other devices can be set in the cabinet. Among them, these electronic devices are generally installed in the lower space 4 of the main body 1, and the upper space 3 of the main body 1 is used to install a refrigerator to dissipate heat for the electronic devices in the lower space 4. As a conventional implementation, the main body 1 of the cabinet is generally rectangular, with four upright main columns, and beams are arranged between the columns to form a cabinet frame with high structural strength and stability. The left side, right side, rear side, bottom side and top side of the frame are provided with sealing plates, while leaving an opening on the front side of the main body 1, and a cabinet door that can be opened and closed is connected at the opening by a hinge. It is easy to understand that the above-mentioned closing component 5 includes the sealing plate and the cabinet door.

[0046] In actual use, condensed water from the refrigerator will accumulate in the upper space 3 of the cabinet, or rainwater from the outside will fall into the upper space 3 of the cabinet due to the upper space 3 being open, so a drainage structure is generally provided on the partition 2 to drain the accumulated water. However, the conventional drainage structure easily causes dirty water marks to appear on the outer surface of the closed component 5 of the cabinet, that is, the sealing plate or the door of the cabinet.

[0047] To solve this problem, refer to Figures 1 to 10 In the cabinet provided in this embodiment, the partition 2 is provided with a drainage portion 6 that passes through from top to bottom at least at a part of its edge, and the drainage portion 6 is located on the inner side of the closing component 5 on a projection plane perpendicular to the vertical direction; the body 1 of the cabinet is provided with a guide groove 7 located on the inner side of the closing component 5 and below the partition 2; the guide groove 7 corresponds to the position of the drainage portion 6, and its opening is upward and adapted to the drainage range of the corresponding drainage portion 6 to receive the liquid discharged by the corresponding drainage portion 6.

[0048] The inner groove wall of the guide groove 7 is located inside the inner edge of the drainage portion 6 on a projection plane perpendicular to the vertical direction. In addition, the inner groove wall of the guide groove 7 extends upward to the partition 2. The guide groove 7 has at least one drainage end 8, and the drainage end 8 is used to discharge the liquid received by the guide groove 7 to the outside of the guide groove 7.

[0049] Preferably, the cabinet is provided with a liquid inlet groove 9 connected to the liquid discharge end 8 of the guide groove 7, the liquid inlet groove 9 extends in the vertical direction and its lower end is open. The liquid inlet groove 9 extends downward to the bottom of the cabinet, and the closing component 5 forms a liquid outlet gap 10 between the bottom of the cabinet and the body 1 of the cabinet.

[0050] In addition, the outer groove walls of the guide groove 7 and the liquid guide groove 9 are installed with waterproof rubber strips 11, and the inner surface of the closing component 5 corresponding to the position of the guide groove 7 is tightly attached to and presses the waterproof rubber strips 11 to close the gap between the guide groove 7, the liquid guide groove 9 and the inner surface of the closing component 5.

[0051] Reference Figure 2 , which shows a partial structure of the cabinet provided in this embodiment. Among them, a plurality of drainage parts 6 are provided at the left and right edge positions of the partition 2, and each of the drainage parts 6 includes a plurality of drainage holes 12 arranged at intervals along the front-to-back direction of the partition 2. Specifically, the drainage parts 6 are arranged at both the left and right positions of the partition 2, and two are provided at the left edge position of the partition 2 along the front-to-back direction, and two are also provided at the right edge position of the partition 2 along the front-to-back direction. In order to correspond to these drainage parts 6, a plurality of guide grooves 7 are provided on the left and right sides of the body 1 of the cabinet, and the guide grooves 7 extend along the front-to-back direction of the cabinet to correspond to the drainage range of the corresponding drainage parts 6, and the front and rear ends of the guide grooves 7 are open to form the drainage ends 8, and the two drainage ends 8 of each of the guide grooves 7 are connected to the liquid guide groove 9.

[0052] Reference Figure 3 In a drainage portion 6, a plurality of drainage holes 12 are arranged at intervals along the front-to-back direction. The cross-section of the drainage holes 12 is rectangular, and the length direction thereof is consistent with the front-to-back direction of the cabinet. Through the drainage holes 12, rainwater, condensed water and other liquids in the upper space 3 can be quickly discharged to the bottom of the partition 2, and the design of the drainage holes 12 being arranged at intervals can also avoid affecting the overall structural strength of the partition 2.

[0053] Reference Figure 4 , Figure 5 and Figure 6, take a guide groove 7 in the body 1 as an example. The guide groove 7 is roughly in the shape of a long strip of groove, and its length direction is parallel to the front-to-back direction of the cabinet. The opening direction of the guide groove 7 is upward to form a guide groove opening 71, and the front and rear ends of the guide groove 7 are open to form two drainage ends 8 respectively. After the guide groove 7 receives the liquid discharged by the drainage part 6, the liquid will flow to the drainage end 8 along the length direction of the guide groove 7. A liquid guide groove 9 is connected to the drainage end 8, and an inclined guide part is provided at the part where the liquid guide groove 9 is connected to the drainage end 8 to guide the liquid to flow more slowly from the guide groove 7 to the liquid guide groove 9. The liquid guide groove 9 extends in the up-down direction, and its opening faces the outside of the cabinet. For example, when the liquid guide groove 9 is located at the front side of the cabinet, its opening direction faces the front side of the cabinet, and when the liquid guide groove 9 is located at the rear side of the cabinet, its opening direction also faces the rear side of the cabinet. The lower end of the liquid guide groove 9 extends to the bottom of the cabinet, and the liquid in the guide groove 7 can be guided to the bottom of the cabinet and then discharged. Among them, the liquid guide groove 9 does not have to be a continuous structure. Because the liquid will move vertically downward under the action of gravity when there is no obstruction, the middle section of the liquid guide groove 9 can be disconnected. For details, please refer to Figure 2 At this time, the water-guiding function of the liquid-guiding groove 9 will not be affected, as long as the liquid-guiding grooves 9 of the upper and lower sections are not staggered in the vertical direction. Fig. 9 A liquid outlet gap 10 is formed between the lower end of the closing component 5 and the body 1. The liquid outlet gap 10 connects the liquid inlet groove 9 with the outside of the cabinet. The liquid in the liquid inlet groove 9 can flow to the outside of the cabinet through the liquid outlet gap 10. Since the liquid outlet gap 10 is located at the bottom of the cabinet, no water marks will be left on the outer surface of the closing component 5. Specifically, the body 1 of the cabinet can be provided with a step-like structure, and the closing component 5 can be located above the step-like structure and form a gap of a certain size with the step surface of the step-like structure. Such a configuration can not only ensure that the outer surface of the cabinet is flat, but also form the above-mentioned liquid outlet gap 10 for liquid discharge.

[0054] Reference Figure 6 and Figure 7 The inner groove wall and the outer groove wall of the water guide groove are respectively the first groove wall 72 and the second groove wall 73 shown in the figure. The first groove wall 72 and the second groove wall 73 are formed by extending upward from the inner and outer edges of the groove bottom of the water guide groove. The second groove wall 73 is lower than the groove bottom, and the first groove wall 72 extends upward from the groove bottom to the lower surface of the partition 2. Fig.10 When the liquid is discharged downward from the drainage hole 12, the liquid will flow into the guide groove 7 along the first groove wall 72, and will not enter the interior of the body 1. The first groove wall 72 of the water guide groove can be fixed to the side surface of the beam of the body 1 by welding, and the beam is located below the partition 2 and fixedly connected to the partition 2, and the beam is located on the inner side of the drainage portion 6 at the corresponding position on the partition 2 to prevent the liquid from entering the interior of the body 1.

[0055] Reference Figure 4 The guide groove 7 and the liquid guide groove 9 are also provided with waterproof rubber strips 11, which play the role of sealing the gap between the sealing component 5 and the body 1 to prevent the external liquid from entering the body 1 of the cabinet. Fig.10 The waterproof rubber strip 11 has a fixing portion 111 for fixing on the cabinet body 1. The fixing portion 111 can be fixedly connected to the cabinet body 1 by various methods such as pasting, clamping, and pressing. At the same time, the front side of the waterproof rubber strip 11 is a deformable deformation portion 112. When the inner surface of the sealing component 5 is in close contact with the deformation portion 112, the deformation portion 112 will be forced to deform, so that the waterproof rubber strip 11 is closely attached to the inner surface of the sealing component 5, thereby blocking the gap between the sealing component 5 and the cabinet body 1, and preventing rainwater, dust, etc. from entering the inside of the cabinet body 1. Among them, the deformation portion 112 can be a hollow structure. The hollow structure makes the waterproof rubber strip 11 have better deformation ability. At the same time, since the waterproof rubber strip 11 is made of elastic materials such as rubber, it can exert a certain force on the inner surface of the sealing component 5 to maintain the state of blocking the gap. In this embodiment, a convex strip 113 extending parallel to the edge of the main body 1 is also provided on the front side of the deformation part 112 of the waterproof rubber strip 11. The convex strip 113 protrudes from the surface of the deformation part 112 and is provided on both the inner and outer sides of the waterproof rubber strip 11. When the closing component 5 is fixed on the main body 1, the edge of the convex strip 113 and the front end of the deformation part 112 will be tightly attached to the inner surface of the closing component 5. At this time, the convex strip 113 located on the upper and lower sides cooperates with the front end of the deformation part 112 to achieve a triple-blocking waterproof effect. In this embodiment, the waterproof rubber strip 11 is installed on the outer groove wall of the guide groove 7 and the liquid guide groove 9. The fixed part 111 of the waterproof rubber strip 11 has a slot 114 suitable for cooperating with the slot wall. The outer groove wall of the guide groove 7 and the liquid guide groove 9 can be inserted into the slot 114 of the waterproof rubber strip 11, so that the waterproof rubber strip 11 is fixedly installed on the main body 1 of the cabinet.

[0056] In the cabinet provided in this embodiment, its body 1 is divided into an upper space 3 and a lower space 4 by a horizontally arranged partition 2, wherein the upper space 3 can be used to install a cold machine, and the lower space 4 can be used to install electronic devices for realizing related functions. In order to ensure the normal operation of the electronic devices in the lower space 4, the surrounding side of the cabinet body 1 is also closed by a closing component 5 to close the lower space 4; wherein, since the upper space 3 above the partition 2 is installed with a cold machine, it is necessary to discharge the condensed water of the cold machine, and at the same time, the upper space 3 is open and water may accumulate, so a drainage portion 6 that runs through from top to bottom is provided at a part of the edge of the partition 2, and the drainage portion 6 is located on the inner side of the closing component 5. In this way, when the liquid in the upper space 3 flows out from the drainage portion When the drain portion 6 flows downward, the liquid will not flow to the outside of the sealing component 5, and will not be contaminated by dust on the outside of the sealing component 5 to leave water marks; however, setting the drain portion 6 to be located on the inside of the sealing component 5 will cause the liquid to be unable to be drained smoothly, and since the drain portion 6 is located on the inside of the sealing component 5, the liquid will also enter the inside of the cabinet body 1; therefore, in this solution, a guide groove 7 is also provided on the cabinet body 1, and the guide groove 7 corresponds to the position of the drain portion 6 and opens upward, and the liquid flowing out of the drain portion 6 will fall into the guide groove 7, which can collect the liquid and guide the liquid to the outside of the cabinet body 1 in a concentrated manner, thereby solving the problem of drainage difficulty after the drain portion 6 is moved inward.
