Description

Technical Field

[0001] The present application relates to the field of batteries, and in particular to a dehumidifier and electrical equipment. Background Art

[0002] During the use of batteries and other equipment, they need to be installed in an environment with a humidity lower than the preset level to reduce the possibility of damage due to moisture. In some cases, in order to reduce the humidity of the environment where the batteries are located, a dehumidifier can be used to dehumidify the air. The water vapor in the air condenses on the cooling plate of the dehumidifier to form condensed water, which is then stored in the water tank. Due to the limited installation space for the equipment, a large amount of space needs to be reserved for structures such as the water tank of the dehumidifier, which greatly reduces the effective utilization rate of the internal space of the equipment. Utility Model Content

[0003] The present application provides a dehumidifier and an electrical device, aiming to improve the problem that the dehumidifier requires a large installation space.

[0004] In order to achieve the above technical effects, a technical solution adopted by the present application is to provide a dehumidifier, comprising:

[0005] A shell body, wherein an air inlet and an air outlet are provided on the shell body;

[0006] A dehumidification component is arranged in the shell, and the dehumidification component is located between the air inlet and the air outlet;

[0007] A drainage groove is arranged in the shell, and the drainage groove is arranged below the dehumidification component to receive the condensed water generated by the dehumidification component; the drainage groove is provided with a drainage port, and the drainage port is arranged toward the air outlet or the air inlet.

[0008] In this example, by facing the drain outlet towards the air outlet, space can be reserved on the same side of the electrical equipment when the dehumidifier is discharging air and draining water, so that drainage and air outlet share the same space on the same side, thereby reducing the installation space required for the dehumidifier; in this example, the drain outlet is directed towards the air inlet, which can also reduce the installation space required for the dehumidifier.

[0009] The shell has a through hole connected to the drain port. In this example, the drain groove is installed in the shell, which can facilitate the docking of the drain groove and the dehumidification component, so that the condensed water generated on the dehumidification component can enter the drain groove more easily, thereby improving the drainage performance of the dehumidifier.

[0010] The drain trough further includes a water outlet pipe, which extends from the drain port to the through hole or extends out of the through hole, and the height of the water outlet pipe gradually decreases from the drain port to the through hole. In this example, by setting the water outlet pipe, the water in the drain trough can be guided to a preset direction through the water outlet pipe; since the drain port and the through hole are connected by the water outlet pipe, the choice of the installation position of the drain trough can be more diverse, and the drain trough can be better adapted to the position of the dehumidification component as needed. In this example, by setting the drain pipe at an angle, the drain pipe can be more convenient for drainage and reduce the accumulation of water in the drain pipe.

[0011] The housing has an upper wall and a lower wall arranged opposite to each other, a first vertical wall is arranged between the upper wall and the lower wall, and the air outlet is arranged on the first vertical wall. In this example, by arranging the air outlet on the first vertical wall, the dehumidifier can discharge air from the side, thereby reducing the overall thickness of the dehumidifier.

[0012] The housing further comprises a second vertical wall adjacent to or opposite to the first vertical wall, an air inlet is provided on the second vertical wall, and the through hole is provided on the first vertical wall or the second vertical wall. In this example, by staggering the second vertical wall where the air inlet is located with the first vertical wall, the wet airflow and the dry airflow can be staggered to improve the dehumidification efficiency.

[0013] The drainage groove has a bottom wall facing the dehumidification component and a side wall arranged at the periphery of the bottom wall. An opening for receiving condensed water is formed above the bottom wall, and a drainage port is provided on the side wall of the drainage groove. By providing a drainage port on the drainage groove, the condensed water on the dehumidification component is directly discharged through the drainage port of the drainage groove, and there is no need to provide an additional water tank for storing water, thereby reducing the problem of secondary condensation on the dehumidification component after evaporation due to water storage in the water tank; in this example, due to the opening on the side wall of the drainage groove, water can be discharged from the side, thereby reducing the space required for the height of the drainage groove and reducing the overall thickness of the dehumidifier.

[0014] The drain port is extended to the bottom wall of the drain groove. In this example, the drain port is extended to the bottom wall of the drain groove, so that the water in the drain groove can be discharged easily and the water accumulation in the drain groove can be reduced.

[0015] The side wall includes a first side wall and a second side wall that are arranged opposite to each other, and a drainage port is provided on the first side wall; the height of the upper surface of the bottom wall gradually decreases from the second side wall to the first side wall. The drainage port in this example is provided on the first side wall, and by gradually decreasing the upper surface of the bottom wall of the drainage groove from the second side wall to the first side wall, the accumulation of condensed water in the drainage groove can be reduced, thereby improving the drainage performance of the drainage groove and reducing the problem of rust of the dehumidification component caused by secondary evaporation of accumulated water.

[0016] The dehumidification component is a semiconductor cooling sheet; the dehumidification component has a first end and a second end, the first end is arranged toward the air inlet, and the drainage groove is arranged below the first end; the second end is arranged toward the air outlet. In this example, by using the semiconductor cooling sheet, the overall volume of the dehumidification component can be reduced, so as to facilitate the miniaturization design of the dehumidifier, so that the dehumidifier can be used inside electrical equipment with a relatively narrow space.

[0017] The end of the first end close to the drainage groove is embedded in the drainage groove. After condensed water is generated on the first end in this example, the condensed water can flow into the drainage groove along the first end. Since the first end can be partially embedded in the drainage groove, on the one hand, the internal space of the drainage groove can be fully utilized, and on the other hand, it helps to reduce the possibility of splashing when the condensed water at the first end drips.

[0018] The first end has a first portion close to the drainage groove and a second portion away from the drainage groove, and the width of the first portion of the first end gradually decreases from the first portion to the second portion. In this example, by gradually decreasing the width of the first portion of the first end, the condensed water on the first end can be gradually gathered toward the second portion, and the gathered condensed water can enter the drainage groove along the first end, so as to reduce the possibility of the condensed water dripping outside the drainage groove.

[0019] Among them, the dehumidifier also includes:

[0020] The electrical component is connected to the housing, and the electrical component is electrically connected to the dehumidification component to control the operation of the dehumidification component. The electronic component in this example is connected to the housing, which can control the operation of the dehumidification component through the electrical component and improve the integration performance of the dehumidifier.

[0021] Among them, a partition is provided in the shell, and the partition separates the shell into a first cavity and a second cavity, the electrical component is provided in the first cavity, the dehumidification component and the drain groove are provided in the second cavity, and the air inlet and the air outlet are respectively connected to the second cavity. In this example, by arranging the electrical component inside the shell, it is convenient to perform waterproof and other sealing operations on the electrical component; by dividing the shell into a first cavity and a second cavity, wherein the second cavity is used for the installation of the dehumidification component and the drain groove, the dehumidification operation is concentrated in the second cavity, reducing the impact of condensed water on the electrical component.

[0022] The dehumidification assembly and the drainage groove are arranged along the first direction, the first cavity and the second cavity are arranged at intervals along the second direction, and the first direction and the second direction are arranged at an angle. In this example, by arranging the first cavity and the second cavity along the second direction, the first cavity and the second cavity can be distributed along the length direction or the width direction of the shell, so as to reduce the overall thickness of the shell of the dehumidifier.

[0023] The housing is provided with a socket assembly, and the electrical assembly is electrically connected to the socket assembly. In this example, by providing the socket assembly, on the one hand, the electrical assembly can be conveniently connected to the external electrical component by quick plugging, and on the other hand, the second cavity can be conveniently sealed.

[0024] The socket assembly and the air outlet are located on the same vertical wall of the housing. In this example, the air outlet outputs dry airflow, and by arranging the socket assembly on the same vertical wall as the air outlet, one side of the socket assembly can be kept dry, thereby reducing the problem of rust on the socket assembly.

[0025] Among them, the dehumidifier also includes:

[0026] The fan is arranged at the air outlet and is electrically connected to the electrical components. In this example, by arranging the fan, the air flow rate can be increased to improve the dehumidification efficiency.

[0027] Among them, the dehumidifier also includes:

[0028] A humidity sensing device, electrically connected to the electrical component, the humidity sensing device is used to detect the humidity at the air inlet;

[0029] The electrical component is also used to control the fan and the dehumidification component to work when the humidity at the air inlet exceeds the preset humidity. In this example, a humidity sensing device is provided to obtain the humidity at the air inlet by using the humidity sensing device to determine whether the dehumidification component performs a dehumidification operation according to the humidity at the air inlet.

[0030] The humidity sensing device is arranged in the housing. In this example, the humidity sensing device is integrated in the housing to improve the integration of the dehumidifier.

[0031] Among them, the dehumidifier also includes:

[0032] An inclination angle sensing device is electrically connected to the electrical component, and is used to detect the inclination angle of the drainage trough;

[0033] The electrical component is also used to control the dehumidification component to work when the inclination angle of the drain groove is lower than a preset angle. In this example, the horizontality of the drain groove is determined by the inclination angle sensing device, and the dehumidification component is turned on when the inclination angle of the drain groove is within the preset range, thereby reducing the problem of water accumulation in the drain groove caused by the excessive inclination angle of the drain groove.

[0034] The present application also proposes an example of an electrical device, including:

[0035] Cabinets; and

[0036] A dehumidifier as in any of the above examples is arranged in a cabinet.

[0037] Among them, the cabinet is provided with a cabinet door, and the air outlet of the dehumidifier is arranged towards the cabinet door; when the dehumidifier is working, the dehumidifier outputs air flow outward, so that a negative pressure state can be formed at the cabinet door of the cabinet, thereby reducing the humid air flow entering the cabinet through the cabinet door, which helps to improve the dryness inside the cabinet.

[0038] Among them, electrical equipment also includes:

[0039] The fire detector is arranged in the cabinet, and the fire detector is arranged at the air inlet or the air outlet of the shell.

[0040] Fire detectors can be used to detect abnormalities such as smoke and gas in the cabinet and transmit signals to the fire control system.

[0041] The cabinet has a top wall, and the dehumidifier is connected to the top wall. The dehumidifier is installed on the top wall to fully utilize the space near the top wall inside the dehumidifier and reduce the space waste in the cabinet.

[0042] The cabinet further comprises a bracket, and the shell is connected to the bracket. By using the bracket as an intermediate connecting piece between the shell and the cabinet, the installation of the dehumidifier can be facilitated on the one hand, and the convenience of the installation of the dehumidifier can be improved on the other hand.

[0043] The cabinet has a floor drain, and the drain port is connected to the floor drain port through a water pipe. The water pipe serves as an intermediate connector between the drain port and the floor drain port to discharge the condensed water generated by the dehumidifier to the outside of the cabinet, thereby reducing the accumulation of condensed water in the cabinet and helping to improve the dryness of the cabinet.

[0057] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0058] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0059] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0060] The multiple terms in the examples of this application refer to at least two (including two).

[0061] Electrical equipment can usually integrate multiple electrical components into a cabinet for easy storage, transportation and installation. Taking an electrical cabinet with batteries as an example, multiple batteries are installed in the electrical cabinet to form an energy storage system. In some cases, the batteries are arranged in an array from bottom to top in the electrical cabinet. When the battery is stored for a long time, the ambient humidity of the battery needs to be kept within a preset range to reduce damage to the battery due to excessive humidity. The batteries described in the examples of this application can be divided into disposable batteries and rechargeable batteries according to whether they are rechargeable. Currently common types of rechargeable batteries are: lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries. The following will mainly describe the embodiments disclosed in this application using lithium-ion batteries as an example. It should be understood that the embodiments disclosed in this application are applicable to any other appropriate type of rechargeable battery. When a lithium-ion battery is placed in an electrical cabinet, it is necessary to keep the electrical cabinet at a preset humidity. Higher or lower than the preset humidity can easily cause the metal parts of the battery to rust or the battery to leak.

[0062] In some cases, in order to reduce the risk of battery rust or leakage in the electric cabinet, the air in the electric cabinet can be dehumidified. Because the batteries in the electric cabinet are usually arranged very compactly, the space that can be reserved in the electric cabinet is very limited, and the space required for the dehumidifier is very large, making it difficult to install the dehumidification equipment directly inside the electric cabinet for dehumidification.

[0063] In response to the above-mentioned problems, the present application proposes a dehumidifier, comprising a shell, a dehumidification component and a drain groove, wherein the shell is provided with an air inlet and an air outlet; the dehumidification component is arranged in the shell, and the dehumidification component is located between the air inlet and the air outlet; the drain groove is connected to the shell, and the drain groove is arranged below the dehumidification component to receive condensed water generated by the dehumidification component; the drain groove is provided with a drain outlet, and the air outlet and the drain outlet are located on the same side of the shell, or the air inlet and the drain outlet are located on the same side of the shell. In the example of the present application, a drainage trough is provided under the dehumidification component to receive the condensed water generated by the dehumidification component, and the condensed water is discharged through a drainage port provided on the side wall of the drainage trough. Therefore, the condensed water generated during the dehumidification process can be directly discharged to the outside without the need to install an additional water storage structure such as a water tank, thereby reducing the overall size of the dehumidifier. In the example of the present application, the air inlet and the drainage port of the drainage trough are provided on the same side. When the dehumidifier is installed, the drainage pipeline and the air inlet of the dehumidifier can share the same space outside the dehumidifier, or the air inlet and the drainage port are located on the same side of the shell, and the drainage port and the air inlet can share the same space outside the dehumidifier, thereby reducing the installation space required for the dehumidifier, thereby enabling the dehumidifier to make full use of the narrow gap on the top of electrical equipment such as electrical cabinets.

[0064] See also Figure 1The dehumidifier in the example of the present application can be used for an electrical device 100, and the cabinet 101 has a cabinet door 102, and the air outlet of the dehumidifier is arranged toward the cabinet door 102. The electrical device 100 in the example of the present application can be an electric cabinet, or it can be other electrical devices. In the present application, by reducing the volume of the dehumidifier 200, the dehumidifier 200 can be installed in a small space such as the top of the cabinet 101, so that the dehumidifier 200 can make full use of the narrow space at the top of the cabinet 101 and improve the space utilization rate in the cabinet 101. In the example of the present application, by making the air outlet 216 of the dehumidifier 200 face the cabinet door 102, the cabinet door 102 can be in a positive pressure state, thereby reducing the amount of humid air flow entering the cabinet 101 from the cabinet door 102.

[0065] One or more dehumidifiers may be provided in the electrical device 100 .

[0066] See also Figure 2 , Figure 3 and Figure 4 An example of a dehumidifier 200 disclosed in the present application includes a shell 210, a dehumidification component 220 and a drain groove 230; the shell 210 is provided with an air inlet 215 and an air outlet 216; the dehumidification component 220 is arranged in the shell 210, and the dehumidification component 220 is located between the air inlet 215 and the air outlet 216; the drain groove 230 is connected to the shell 210, and the drain groove 230 is arranged below the dehumidification component 220, for receiving condensed water generated by the dehumidification component 220; the drain groove 230 is provided with a drain outlet 233, and the drain outlet 233 is arranged toward the air outlet 216.

[0067] The shell 210 is at least partially hollow, and an inner cavity is formed inside the shell 210, and the inner cavity is used to place the dehumidification component 220. The air inlet 215 and the air outlet 216 are through holes opened on the shell 210, and the air inlet 215 and the air outlet 216 are respectively connected to the inner cavity of the shell 210. The air flow can enter the shell 210 from the air inlet 215 and be output from the air outlet 216. The shell 210 of the dehumidifier 200 in this example can be a rectangular parallelepiped structure as a whole, such as Figure 2 For example, the first direction 2a may be the height direction of the dehumidifier 200, and the second direction 2b may be the length direction of the dehumidifier 200. Optionally, the housing 210 of the dehumidifier 200 may also be in other shapes. In this example, the dehumidification assembly 220 is arranged above the drain groove 230 along the first direction 2a.

[0068] See also Figure 5, the dehumidification component 220 is used to dehumidify the airflow entering the air inlet 215. The dehumidification component 220 in this example is installed in the channel between the air inlet 215 and the air outlet 216, so that the humid airflow entering the shell 210 from the air inlet 215 can contact the dehumidification component 220, and the water vapor in the humid airflow forms condensed water under the action of the dehumidification component 220, and the dehumidified dry airflow is output to the outside of the shell 210 through the air outlet 216. The dehumidification component 220 in this example can have fins or condensation tubes for heat exchange with the humid airflow. Taking the fins as an example, when the airflow entering the shell 210 from the air inlet 215 flows through the fins, heat exchange is performed with the fins, so that the water vapor in the airflow condenses on the fins to form condensed water; when the airflow continues to flow to the air outlet 216, the humidity of the airflow decreases, and the dry airflow is output to the outside of the shell 210 through the air outlet 216. The dehumidification component 220 in this example may be a compression refrigeration component. Optionally, the dehumidification component 220 in the example of the present application may also be a semiconductor refrigeration sheet or other refrigeration equipment that can be used to condense water vapor in the airflow.

[0069] See also Figure 5 , Figure 6 and Figure 7The drain groove 230 is installed below the dehumidification component 220 to receive the condensed water generated by the dehumidification component 220. When the dehumidifier 200 is in use, the side of the dehumidification component 220 facing the ground is the bottom of the dehumidification component 220, and the condensed water generated on the dehumidification component 220 can flow downward from top to bottom under the action of gravity; the side of the drain groove 230 facing away from the ground is the top of the drain groove 230, and the side of the drain groove 230 facing the ground is the bottom of the drain groove 230, and the condensed water on the dehumidification component 220 above the drain groove 230 can flow downward into the drain groove 230. The water receiving trough has a bottom wall 231 and a side wall 232, wherein the side wall 232 is arranged at the periphery of the bottom wall 231 and extends upward to form an opening above the bottom wall 231, and the opening is arranged corresponding to the dehumidification component 220, so that the condensed water generated by the dehumidification component 220 can enter the drainage trough 230 through the opening; the side wall 232 in this example can be surrounded by the periphery of the bottom wall 231 to form an annular structure, and the annular structure can be a polygonal ring, such as a quadrilateral ring, or a circular ring structure. Optionally in this example, when the dehumidification component 220 has the above-mentioned fins or condensation tubes for condensing water vapor in the airflow, the drainage trough 230 can be arranged below the fins or condensation tubes, so that the drainage trough 230 can receive the condensed water. Optionally, the drain groove 230 in this example can be connected to the dehumidification component 220, so that the opening of the drain groove 230 can correspond to the setting of the dehumidification component 220, and the condensed water generated by the dehumidification component 220 can directly drip into the drain groove 230. In this example, the water received by the drain groove 230 is directly discharged to the outside of the dehumidifier 200, and there is no need to set up an additional water tank, thereby reducing the volume of the dehumidifier 200, so that the dehumidifier 200 can make full use of the narrow installation space in the electrical device 100. In this example, the condensed water can be directly discharged from the drain port 233, and the dehumidifier 200 does not use a water tank to store the condensed water, thereby reducing the problem of secondary condensation of water vapor caused by water evaporation in the water tank.

[0070] Please refer to Figure 2In this example, the air outlet 216 and the drain port 233 are arranged on the same side of the housing 210. Optionally, the housing 210 has an upper wall 211 and a lower wall 212 arranged opposite to each other, a first vertical wall 213 is arranged between the upper wall 211 and the lower wall 212, and the air outlet is arranged on the first vertical wall 213. In this example, the lower wall 212 of the housing 210 can be a side wall of the housing 210 facing the ground when the dehumidifier 200 is in use, the upper wall 211 of the housing 210 is a side wall of the housing 210 facing away from the ground, the first vertical wall 213 is located between the upper wall 211 and the lower wall 212, the first vertical wall 213 can be arranged vertically to the ground, the first vertical wall 213 can also be arranged at a certain angle to the ground, the first vertical wall 213 can be the front side wall of the housing 210 when the dehumidifier 200 is in use, or it can be the rear side or other orientation wall of the housing 210. Optionally, in some examples, the through hole 2131 and the air outlet 216 are both arranged on the first vertical wall 213. Taking the example where the air outlet 216 is a through hole opened on the first vertical wall 213 of the shell 210 and the first vertical wall 213 is the front wall of the shell 210, the drain outlet 233 is also arranged toward the front side of the shell 210, so that the air outlet 216 and the drain outlet 233 are both located on the front side of the shell 210. When the dry airflow generated by the dehumidifier 200 is output, the portion of the outside of the dehumidifier 200 corresponding to the air outlet 216 needs to have a certain space to form a flow channel for the dry airflow so that the dry airflow can flow in a preset direction; when the condensed water generated by the dehumidification component 220 is discharged to the outside, the drainage pipe connected to the outside of the electrical device 100 also requires a certain installation space. In this example, by arranging the air outlet 216 and the drainage port 233 on the same side, the drainage pipe on the electrical device 100 and the flow channel for the dry airflow output by the dehumidifier 200 can share the same space. When the dehumidifier 200 is in use, the space reserved for the dehumidifier 200 in the electrical device 100 can be relatively smaller to make full use of the internal space of the electrical device 100.

[0071] In some examples, the difference from the above examples is that the drain outlet 233 is arranged toward the air inlet 215. During the use of the dehumidifier 200, a certain space is usually required to be reserved at the air inlet 215 to form moisture circulation to provide a channel for the flow of moist air. The pipeline connecting the drain outlet 233 can be arranged in the moist air flow channel to make full use of the internal space of the electrical equipment 100.

[0072] In some examples, the drain groove 230 is disposed inside the housing 210 and below the dehumidification assembly 220 to receive the condensed water generated by the dehumidification assembly 220; by integrating the drain groove 230 inside the housing 210, the installation of the dehumidifier 200 can be facilitated. In some examples, the drain groove 230 is installed below the housing 210 and is disposed corresponding to the dehumidification assembly 220. The housing 210 has a lower wall 212 and an upper wall 211 disposed opposite to each other. A through hole is provided on the lower wall 212 of the housing 210 so that the condensed water generated by the dehumidification assembly 220 falls into the drain groove 230 through the through hole on the lower wall 212.

[0073] In some examples, in order to accelerate the flow of air, a fan 250 may be provided inside or outside the dehumidifier 200 so that the air can flow from the air inlet 215 to the air outlet 216. The fan 250 in this example may be provided inside the housing 210, or outside the housing 210; when the dehumidifier 200 is installed in the cabinet 101 of the electrical device 100, the fan 250 may also be provided inside the electrical device 100, and the fan 250 is used to transport the airflow in a preset direction so that the wet airflow can enter the housing 210 through the air inlet 215, and the dry airflow after being dehumidified by the dehumidification component 220 can be output from the air outlet 216 to the outside of the housing 210.

[0074] In some examples, the drain groove 230 is provided in the housing 210, and a through hole 2131 is provided on the housing 210, and the through hole 2131 is connected to the drain port 233. In this example, the drain groove 230 is integrated inside the housing 210 so that the drain groove 230 can make full use of the internal space of the housing 210, and the drain groove 230 is also easier to align with the dehumidification component 220, so that the condensed water generated by the dehumidification component 220 can more easily flow in the direction of the drain groove 230. The through hole 2131 is set through the housing 210 to connect the inner cavity of the housing 210, and the drain port 233 is connected to the through hole 2131, so that the condensed water output from the drain port 233 can be output to the outside of the dehumidifier 200 along the through hole 2131. Since the drainage groove 230 can be integrated in the shell 210, on the one hand, there is no need to open a through hole connecting the drainage groove 230 on the other wall surfaces of the shell 210, which can reduce the processing process of the shell 210; on the other hand, the other wall surfaces of the shell 210 can remain relatively flat, so that the dehumidifier 200 can better adapt to the narrow space inside the electrical equipment 100.

[0075] Please refer to Figure 7In some examples, the drain trough 230 also includes an outlet pipe 234, and the outlet pipe 234 extends from the drain port 233 to the through hole 2131, or the outlet pipe 234 extends from the drain port 233 to the through hole 2131, and the height of the outlet pipe 234 gradually decreases from the drain port 233 to the through hole 2131. The outlet pipe 234 in this example can be a straight pipe, or a curved pipe. In this example, by connecting the drain port 233 and the through hole 2131 through the outlet pipe 234, a certain deformable space is provided between the drain trough 230 and the wall surface of the shell 210 on which the through hole 2131 is provided, and the drain trough 230 can be installed at any position in the shell 210, so as to improve the convenience of assembling the drain trough 230 and the dehumidification component 220 in the shell 210. The height of the water outlet pipe 234 gradually decreases from the drain port 233 toward the through hole 2131, which means that when the dehumidifier 200 is installed at a preset position, the height of the water flow path formed by the water outlet pipe 234 from the ground gradually decreases, so that a channel with a gradually decreasing height is formed in the water outlet pipe 234. The water discharged from the drain port 233 can flow along the water outlet pipe 234 toward the through hole 2131 under the action of gravity, so as to discharge the condensed water.

[0076] See also Figure 2 In some examples, the housing 210 has an upper wall 211 and a lower wall 212 that are arranged opposite to each other, a first vertical wall 213 is arranged between the upper wall 211 and the lower wall 212, and the air outlet is arranged on the first vertical wall 213. The upper wall 211 and the lower wall 212 in this example can form the upper and lower surfaces of the housing 210, wherein the lower wall 212 is the wall surface of the housing 210 facing the ground when the dehumidifier 200 is in use, and the direction from the lower wall 212 to the upper wall 211 is the height direction of the housing 210. In some examples, the air outlet and the through hole are both located on the first vertical wall. The first vertical wall 213 is arranged between the upper wall 211 and the lower wall 212, and the through hole 2131 and the air outlet are both arranged on the first vertical wall 213, so that the air outlet 216 and the through hole correspond to the side of the housing 210. When installing the dehumidifier 200, a certain amount of space needs to be reserved outside the air outlet 216 of the dehumidifier 200 to form an air flow channel. In this example, by setting the air outlet 216 and the through hole 2131 on the first vertical wall 213, an air flow channel can be reserved from the side of the shell 210, and the space required in the height direction of the shell 210 is reduced, so that the dehumidifier 200 can be installed in the narrow space at the top of the electrical equipment 100.

[0077] See also Figure 3In some examples, the housing 210 further has a second vertical wall 214 disposed adjacent to or opposite to the first vertical wall 213, an air inlet 215 is provided on the second vertical wall 214, and a through hole is provided on the first vertical wall 213 or the second vertical wall 214. In this example, the dry air generated after dehumidification by the dehumidification component 220 can be output from the air outlet 216. The second vertical wall 214 is disposed adjacent to or opposite to the first vertical wall 213, which means that the second vertical wall 214 and the first vertical wall 213 are not in the same plane. In this example, the second vertical wall 214 can be a wall surface opposite to the first vertical wall 213, or the second vertical wall 214 can be a wall surface adjacent to the first vertical wall 213. In this example, an air outlet 216 connected to the inner cavity of the shell 210 can be set on the second vertical wall 214 or the first vertical wall 213. The humid air flow can enter the dehumidification component 220 from the air inlet 215, and form a dry air flow after being dehumidified by the dehumidification component 220. The dry air flow can be output through the air outlet 216 on the second vertical wall 214 or the first vertical wall 213.

[0078] See also Figure 5 , Figure 6 and Figure 7 In some examples, the drain groove 230 has a bottom wall 231 facing the dehumidification component 220 and a side wall 232 arranged at the periphery of the bottom wall 231, an opening is formed above the bottom wall 231 for receiving condensed water generated by the dehumidification component 220, and a drain port 233 is opened on the side wall 232 of the drain groove 230.

[0079] The bottom wall 231 in this example is a side wall of the drain trough 230 facing the ground when in use, and the side wall 232 can be perpendicular to the ground, or the side wall 232 can be inclined at a certain angle to the ground. The drain port 233 is arranged on the side wall 232 of the drain trough 230 so that the drain trough 230 can discharge water from the side. Since the condensed water is discharged from the side wall 232 of the drain trough 230 in this example, the space below the drain trough 230 can be not occupied during drainage, which can facilitate reducing the height of the drain trough 230 and further reduce the thickness of the dehumidifier 200. The drain port 233 in this example can be arranged at any position of the side wall 232 of the drain trough 230, or the drain port 233 can be arranged at a position close to the middle in the length direction of the drain trough 230.

[0080] In some examples, the drain port 233 extends to the bottom wall 231 of the drain groove 230 so that condensed water entering the drain groove 230 can be directly discharged from the drain port 233, reducing water accumulation in the drain groove 230 and further reducing secondary evaporation of water in the drain groove 230.

[0081] In some examples, the side wall 232 includes a first side wall 2321 and a second side wall 2322 that are arranged opposite to each other, and a drain port 233 is provided on the first side wall 2321; the height of the upper surface of the bottom wall 231 gradually decreases from the second side wall 2322 to the first side wall 2321. In this example, the first side wall 2321 can be the wall surface of the front side of the drain groove 230, or can be other wall surfaces, the second side wall 2322 is staggered with the first side wall 2321, and the drain port 233 is provided on the first side wall 2321. From the second side wall 2322 to the first side wall 2321, the height of the upper surface of the bottom wall 231 gradually decreases, which means that the height of the bottom surface of the drain groove 230 at the corresponding position of the drain outlet 233 on the inner side of the drain groove 230 is relatively lower, and the upper surface of the bottom wall 231 of the drain groove 230 forms a diversion slope for diverting the condensed water to the direction of the drain outlet 233, and the condensed water entering the drain groove 230 can flow along the diversion slope toward the drain outlet 233. In this example, by forming an inclined upper surface on the bottom wall 231 of the drain groove 230, it is convenient to divert the condensed water, so that the condensed water in the drain groove 230 can flow toward the drain outlet 233 as much as possible, thereby reducing the accumulation of water in the drain groove 230, and further reducing the problem of damage to the dehumidification component 220 due to secondary condensation of water vapor. The drain groove 230 in this example can be a rectangular parallelepiped structure as a whole, and optionally, the drain groove 230 can also be a cubic structure of other shapes. In some examples, along the first direction 2a, the heights of the first side wall 2321 and the second side wall 2322 may be equal; optionally, the heights of the first side wall 2321 and the second side wall 2322 may also be unequal, and the bottom wall 231 connects the first side wall 2321 and the second side wall 2322. In this example, the bottom wall 231 may be inclined as a whole.

[0082] Please refer to Figure 5 and Figure 8 The dehumidification component 220 is a semiconductor refrigeration sheet; the semiconductor refrigeration sheet has a first end 221 and a second end 222, the first end 221 is arranged toward the air inlet 215, and the drainage groove 230 is arranged below the first end; the second end 222 is arranged toward the air outlet 216. The semiconductor refrigeration sheet has a first end 221, and the first end 221 is used for heat exchange with the humid air flow. The water vapor in the humid air flow can condense on the first end 221 to form condensed water to remove the water vapor in the air flow and form a dry air flow. The first end 221 in this example can be a long sheet structure, and the first end 221 can be along the following lines: Figure 2 The first end 221 is extended in the first direction 2a so that the condensed water on the first end 221 can flow along the first end 221 toward the drain groove 230. Optionally, the first end 221 in this example can be a cold end fin of a semiconductor refrigeration plate, and the second end 222 can be a hot end fin of a semiconductor refrigeration plate.

[0083] The second end 222 is used to generate heat so that the dry airflow after passing through the first end 221 is heated to accelerate the diffusion efficiency of the dry airflow, thereby accelerating the heat dissipation. In this example, the second end 222 is arranged toward the air outlet 216 so that the dry airflow can flow toward the air outlet 216 after passing through the second end 222. In this example, by adopting a semiconductor cooling sheet, the Peltier effect can be adopted to form a state where the first end 221 absorbs heat and the second end 222 releases heat, so that the water vapor in the wet airflow forms condensed water under the action of the first end 221, and the formed dry airflow can diffuse toward the air outlet 216 under the action of the second end 222. Optionally, the dehumidification component 220 can also have a semiconductor conduction band arranged between the first end 221 and the second end 222, a copper electrode is arranged between the semiconductor conduction band and the first end 221, and a copper electrode is also arranged between the semiconductor conduction band and the second end 222, so that the first end 221, the second end 222, the metal electrode and the semiconductor conduction band are combined to form a semiconductor cooling sheet. Since there is no need to use a compressor or other structures for heat exchange, the overall volume of the dehumidification component 220 can be reduced, and the dehumidifier 200 can be designed to be miniaturized, so that the dehumidifier 200 can make full use of the narrow installation space such as the top of the electrical equipment 100 such as the electric cabinet. The drainage groove 230 in this example is arranged below the first end 221, so that the condensed water generated by the first end 221 can enter the drainage groove 230, and the condensed water can be discharged in time through the drainage port 233 on the drainage groove 230, thereby reducing the problem of secondary condensation caused by the evaporation of accumulated water. In this example, the semiconductor cooling sheet and the drainage groove 230 are matched, and the thickness of the dehumidification component 220 and the drainage groove 230 can be reduced at the same time, and the overall thickness of the dehumidifier 200 can be reduced, so that the dehumidifier 200 can be installed in the narrow space at the top of the electrical equipment 100.

[0084] See also Figure 5In some examples, one end of the first end 221 close to the drain groove 230 is embedded in the drain groove 230. In this example, one end of the first end 221 close to the drain groove 230 extends into the drain groove 230, so that the condensed water on the first end 221 can flow along the first end 221 to the drain groove 230. By reducing the distance between the first end 221 and the bottom wall 231 of the drain groove 230, the problem of condensed water splashing from the drain groove 230 when dripping from the first end 221 can be reduced. In this example, after the end of the first end 221 is embedded in the drain groove 230, the overall thickness of the first end 221 and the drain groove 230 in the first direction 2a can be reduced, thereby helping to reduce the overall thickness of the dehumidifier 200. Optionally, in some examples, a guide slope as described in the above examples is formed on the bottom wall 231 of the drain groove 230, and the first end 221 is arranged close to one end of the drain groove 230 toward the guide slope so that condensed water flowing downstream along the first end 221 can drip onto the guide slope to reduce water accumulation in the drain groove 230.

[0085] See also Figure 5 In some examples, the first end 221 has a first portion 2211 close to the drain groove 230 and a second portion 2212 away from the drain groove 230, and the width of the first portion 2211 of the first end 221 gradually decreases from the second portion 2212 of the first end 221 to the first portion 2211. In this example, the first portion 2211 can be arranged at the first end 221 along the Figure 2 The second part 2212 can be arranged at one end in the first direction 2a described in the figure, and the second part 2212 can be arranged at the other end of the first end 221 in the first direction 2a. From the second part 2212 to the first part 2211, the first part 2211 of the first end 221 is in a state where the width gradually decreases, so that a slope is formed on the first part 2211 of the first end 221, and the condensed water can flow along the slope on the first end 221 to a preset position. Optionally, in some examples, a guide slope as described in the above examples is formed on the bottom wall 231 of the drain groove 230, and the first part 2211 of the first end 221 is embedded in the drain groove 230 and arranged toward the guide slope. When the condensed water on the first end 221 flows downward along the first part 2211, it can be guided along the slope formed on the first part 2211 to the guide slope position, so as to reduce the possibility of the condensed water splashing out of the drain groove 230.

[0086] In some examples, the dehumidifier 200 further includes an electrical component 240, which is connected to the housing 210, and the electrical component 240 is electrically connected to the dehumidification component 220, and is used to control the operation of the dehumidification component 220. The electrical component 240 is installed on the housing 210 and is electrically connected to the dehumidification component 220, so that the electrical component 240 can control the operation of the dehumidification component 220. The electrical component 240 in this example can be used to control the working states such as the start time, stop time, and operation time of the dehumidification component 220. The electrical component 240 in this example can control the dehumidifier 200 to run for a preset time, or the electrical component 240 can also control the dehumidifier 200 to run periodically, or the electrical component 240 can also control the dehumidifier 200 to run when other preset conditions (such as the ambient humidity exceeds the preset humidity) are met. In this example, by integrating the electrical component 240 on the housing 210, the control of the dehumidification component 220 can be facilitated, and the integration effect of the dehumidifier 200 can be improved. The electrical component 240 in this example can be arranged inside the housing 210, or outside the housing 210. The electrical component 240 in this example can include modules such as circuit boards with functions such as power conversion, communication processing, temperature and humidity processing, and control of the dehumidification component 220, and the electrical component 240 can also include other functional modules.

[0087] In some examples, a partition 217 is provided in the housing 210, and the partition 217 divides the housing 210 into a first cavity 218 and a second cavity 219, the electrical component 240 is provided in the first cavity 218, the dehumidification component 220 and the drain groove 230 are provided in the second cavity 219, and the air inlet 215 and the air outlet 216 are respectively connected to the second cavity 219. The partition 217 is a plate-shaped structure provided inside the housing 210, and the housing 210 has an inner cavity. The partition 217 divides the inner cavity of the housing 210 into a first cavity 218 and a second cavity 219, wherein the first cavity 218 is used to install the electrical component 240, and the second cavity 219 is used to install the dehumidification component 220 and the drain groove 230. In this example, the air inlet 215 and the air outlet 216 are connected to the second cavity 219, so that the humid air flow is only input through the second cavity 219 and output from the second cavity 219. Since the electrical component 240 is separated in the first cavity 218, the electrical component 240 can be staggered with the humid airflow, and the electrical component 240 can be easily sealed to improve the reliability of the electrical component 240. In this example, the partition 217 divides the inner cavity of the shell 210 into two cavities, and the connection between the partition 217 and the inner wall of the shell 210 can be provided with a sealing gasket and other structures for sealing to improve the moisture-proof performance of the electrical component 240. In this example, the electrical component 240 and the dehumidification component 220 can be electrically connected through a wire or other connector; in order to connect the electrical component and the dehumidification component 220 nearby, the wire and other connectors between the electrical component 240 and the dehumidification component 220 can be set through the partition 217, and the sealing ring and other structures can be set at the connection between the connector and the partition 217 for sealing to reduce the humid airflow in the second cavity 219 from entering the first cavity 218.

[0088] In some examples, the dehumidification component 220 and the drainage groove 230 are arranged along the first direction 2a, the first cavity 218 and the second cavity 219 are arranged at intervals along the second direction 2b, and the first direction 2a and the second direction 2b are arranged at an angle. The dehumidification component 220 and the drainage groove 230 in this example can be arranged along the height direction of the dehumidifier 200, and the first cavity 218 and the second cavity 219 are arranged at intervals along the second direction 2b. The first direction 2a and the second direction 2b are arranged at an angle, which means that the first direction 2a and the second direction 2b are not parallel. Optionally, in this example, the second direction 2b can be arranged perpendicular to the first direction 2a. Since the first cavity 218 and the second cavity 219 are arranged at intervals along the second direction 2b, the space occupied by the electrical component 240 in the height direction of the dehumidifier 200 can be reduced, so as to reduce the thickness of the dehumidification component 220, so that the dehumidifier 200 can be installed in a narrow space such as the top of the electric cabinet.

[0089] In some examples, a socket assembly 241 is provided on the housing 210, and the electrical assembly 240 is electrically connected to the socket assembly 241. In this example, by providing the socket assembly 241, the electrical assembly 240 and the socket assembly 241 can be conveniently connected quickly, and the electrical assembly 240 in this example can be plugged into the socket assembly 241. The socket assembly 241 can also be used to connect structures such as an external power supply. The socket assembly 241 in this example can be an aviation plug, or it can be other socket structures that can perform electrical connections.

[0090] In some examples, the socket assembly 241 and the air outlet 216 are located on the same vertical wall of the housing 210. After the humid air flow is dehumidified by the dehumidification assembly 220, the formed dry air flow is output to the outside of the housing 210 through the air outlet 216. In this example, the socket assembly 241 and the air outlet 216 are located on the same vertical wall of the housing 210, so that the humidity on the side of the housing 210 where the air outlet 216 is provided is relatively low. After the socket assembly 241 is installed, the humidity on the side where the socket assembly 241 is located is relatively lower. On the one hand, the possibility of condensation water on the socket assembly 241 can be reduced to reduce the problem of rust on the socket assembly 241; on the other hand, the possibility of humid air flow entering the first cavity 218 through one side of the socket assembly 241 can be reduced, which helps to improve the moisture-proof performance of the electrical assembly 240.

[0091] In some examples, the dehumidifier 200 further includes a fan 250, which is disposed at the air outlet 216, and the fan 250 is electrically connected to the electrical component 240. The fan 250 in this example is used to accelerate the airflow from the air inlet 215 to the air outlet 216, thereby improving the dehumidification efficiency of the dehumidifier 200. The fan 250 in this example can be disposed at a position near the air outlet 216 outside the housing 210, and the fan 250 can also be disposed between the dehumidification component 220 and the air outlet 216. The fan 250 is electrically connected to the electrical component 240, and when the electrical component 240 controls the operation of the dehumidification component 220, the electrical component 240 can simultaneously control the operation of the fan 250, so that the fan 250 and the dehumidification component 220 can work synchronously.

[0092] See also Fig. 9 In some examples, the dehumidifier 200 also includes a humidity sensor, and the humidity sensing device 242 is electrically connected to the electrical component, and the humidity sensing device 242 is used to detect the humidity at the air inlet 215; the electrical component 240 is also used to control the operation of the fan 250 and the dehumidification component 220 when the humidity at the air inlet 215 exceeds the preset humidity.

[0093] The humidity sensing device 242 in this example can be a humidity sensor or other equipment for detecting humidity. The humidity sensor is used to detect the humidity at the air inlet 215, and the electrical component 240 is electrically connected to the humidity sensing device 242 so that the electrical component 240 can obtain a humidity signal. In this example, when the humidity at the air inlet 215 exceeds the preset humidity, the electrical component 240 sends an electrical signal to the dehumidification component 220, and the electrical signal described in this example can be a high-level signal or a low-level signal to trigger the dehumidification component 220 to start. In this example, when the humidity sensing device 242 detects that the humidity at the air inlet 215 is at the preset humidity, the electrical component 240 can control the dehumidification component 220 to stop running. Optionally, in this example, when the humidity sensing device 242 detects that the air humidity is higher than 70%, the electrical component 240 can control the dehumidification component 220 to start, and when the humidity sensing device 242 detects that the air humidity is lower than 50%, the electrical component 240 can control the dehumidification component 220 to stop running. The preset humidity in this example can also be other numerical ranges, and the preset humidity can be determined according to specific circumstances. In this example, the humidity at the air inlet 215 is detected by the humidity sensing device 242, so as to open the dehumidification component 220 when necessary, thereby reducing the energy consumption of the dehumidifier 200. The humidity sensing device 242 in this example can be arranged between the air inlet 215 and the dehumidification component 220, or can be installed inside the through hole of the air inlet 215. The humidity sensing device 242 can also be arranged outside the housing 210 at a position corresponding to the air inlet.

[0094] In some examples, the humidity sensing device 242 is disposed in the housing 210 so that the humidity sensing device 242 is integrated inside the dehumidifier 200. In this example, by integrating the humidity sensing device 242 into the housing 210, the integration characteristics of the dehumidifier 200 can be improved. The humidity sensing device 242 in this example can be electrically connected to the electrical component 240 using the connector described in the above example.

[0095] See also Fig. 9 In some examples, the dehumidifier 200 also includes a tilt angle sensing device 243, which is electrically connected to the electrical component 240, and the tilt angle sensing device 243 is used to detect the tilt angle of the drain groove 230; the electrical component is also used to control the dehumidification component 220 to operate when the tilt angle of the drain groove 230 is lower than a preset angle.

[0096] The tilt angle sensing device 243 may be a tilt angle sensor for detecting the tilt angle of the drain trough 230. The tilt angle of the drain trough 230 in this example may be the tilt angle of the bottom surface of the first side wall 2321 or the second side wall 2322 of the drain trough 230 relative to the ground, or may be the tilt angle of other parts of the drain trough 230 relative to the ground. The tilt angle sensing device 243 detects the tilt angle of the drain trough 230, and the electrical component 240 controls the operating state of the dehumidification component 220 according to the tilt angle of the drain trough 230. In this example, when the tilt angle of the drain trough 230 is lower than a preset angle, for example, when the tilt angle of the lower end of the first side wall 2321 of the drain trough 230 is lower than 5°, the electrical component 240 controls the operation of the dehumidification component 220. In this example, by detecting the inclination angle of the drain groove 230, when the inclination angle of the drain groove 230 is within a preset range, the dehumidification component 220 is controlled to work, and when the inclination angle of the drain groove 230 exceeds the preset angle, the dehumidifier 200 component does not work, so as to reduce the problem that the drain groove 230 cannot drain water normally when the inclination angle of the dehumidification component 220 is too large, thereby reducing the problem of water accumulation inside the drain groove 230. Optionally, in this example, an alarm device, such as an alarm light or a buzzer, can be set, and when the inclination angle of the drain groove is higher than the preset range, the electrical component controls the alarm device to alarm.

[0097] The present application also provides an example of an electrical device 100 , including a cabinet 101 and a dehumidifier 200 as described in any of the above examples. The dehumidifier 200 is disposed in the cabinet 101 .

[0098] The cabinet 101 can be used to place batteries, and the batteries are placed from bottom to top in the cabinet 101, or according to other preset rules. By setting a dehumidifier in the cabinet 101, the humidity in the cabinet can be reduced to reduce problems such as short circuits of the batteries due to moisture. The cabinet 101 usually has a cabinet door, and batteries and other structures can be put in or taken out through the cabinet door 102. In this example, one or more dehumidifiers can be set in the cabinet. When multiple dehumidifiers are set, multiple dehumidifiers can be set on the same side of the cabinet. For example, multiple dehumidifiers can be installed on the top of the cabinet; multiple dehumidifiers can also be set at different positions in the cabinet at intervals. For example, dehumidifiers can be set at the top, middle and bottom of the cabinet.

[0099] In this example, the dehumidifier can be directly connected to the cabinet, for example, the dehumidifier can be connected and fixed to the cabinet by welding, bonding, etc.; optionally, the dehumidifier can also be connected to the cabinet through an intermediate connector, for example, the dehumidifier can be connected to the cabinet through an intermediate connector such as a bracket or a clamp. In the example of this application, since there is usually a certain gap between the air outlet 216 of the dehumidifier 200 and the cabinet door 102 so that the dry air flow can be output to the inside of the cabinet 101, the pipe connected to the drain port 233 can be set in the gap between the air outlet 216 and the cabinet door 102, thereby making full use of the space in the cabinet 101.

[0100] It is understandable that the electrical device 100 in this example includes the example of the dehumidifier 200 described in any of the above examples, and also includes all the technical effects of the above example of the dehumidifier 200, which will not be repeated. The electrical device 100 in this example may also include other functional components, which will not be repeated.

[0101] In some examples, the cabinet 101 is provided with a cabinet door 102; the air outlet 216 of the dehumidifier 200 is arranged toward the cabinet door 102. The air outlet 216 of the dehumidifier 200 is arranged toward the cabinet door 102. When the dehumidifier 200 dehumidifies the airflow, the wet airflow enters the housing 210, and the wet airflow is dried by the dehumidification component 220 to form a dry airflow. The dry air generated by the dehumidifier 200 is transported toward the cabinet door 102, so that the cabinet door 102 is in a positive pressure state, thereby reducing the wet airflow from the cabinet door 102 into the cabinet 101.

[0102] See also Fig.10 In some examples, the electrical device further includes a fire detector 104, which is disposed in the cabinet 101, and the fire detector 104 is disposed at an air inlet or an air outlet of the shell.

[0103] The fire detector 104 can be used to detect at least one of the temperature, humidity and other signals in the cabinet 101. The fire detector 104 is used to detect abnormalities of smoke, gas and the like in the cabinet 101, and transmit the signal to the fire control system. The fire detector 104 may include a smoke detector, a gas detector and the like. The fire detector 104 in this example may be arranged at the air inlet or outlet of the dehumidifier 200. When the fire detector 104 detects that at least one signal such as smoke or gas in the cabinet 101 exceeds a preset threshold, the fire detector may sound an alarm. When a dehumidifier 200 is provided in the cabinet 101, under the action of the dehumidifier, the humidity in the cabinet can be kept at a preset threshold, which can reduce the problems such as short circuits of components such as batteries in the cabinet on the one hand, and can be used to monitor thermal runaway of batteries inside electrical equipment on the other hand, thereby improving the reliability of the operation of the electrical equipment.

[0104] The fire detector 104 is arranged at the air inlet or outlet of the housing. Optionally, the fire detector is arranged at the air outlet of the housing. Since the air outlet can output dry airflow, the fire detector detects smoke or gas signals inside the cabinet at the air outlet, which can reduce the possibility of false alarm of the fire detector.

[0105] The fire detector 104 may have an alarm 105 and a controller 103, wherein the alarm 105 is connected to the controller, and the controller 103 is used to control the alarm 105 to alarm according to the operation signal of the electrical equipment. The alarm 105 may be a sound alarm, a light alarm or an electric signal alarm, or a combination of multiple alarm modes. The alarm 105 may be installed on the outside of the cabinet 101. Optionally, the alarm 105 may be integrated with the fire detector 104. The controller 103 may be an electric control board or other functional structure, and the controller 103 alarm 105. When the fire detector 104 detects that the temperature or humidity in the electrical equipment exceeds a preset threshold, the controller 103 may control the alarm 105 to alarm for prompting. Optionally in this example, at least one of the fire detector 104 and the alarm 105 may be integrated with the controller 103 on the same circuit board. Alternatively, the fire detector 104 can be connected to other control devices or alarm devices to control the working status of the fire detector 104 through other control devices. When the fire detector 104 detects smoke or gas components and needs to alarm, it can send an alarm signal to the alarm device for alarm.

[0106] Please refer to Fig.11 In some examples, the cabinet 101 has a top wall, and the dehumidifier 200 is disposed below the top wall.

[0107] In this example, the top wall of the cabinet 101 can be the wall surface at the upper end of the cabinet 101. The top wall of the cabinet 101 can be composed of a layered structure, and the top wall of the cabinet 101 can also be composed of a composite layered structure. The dehumidifier 200 is installed below the top wall. The dehumidifier 200 can be directly connected to the top wall, and the dehumidifier 200 can also be connected to the top wall through an intermediate connector. When placing modules such as batteries in the cabinet 101, the batteries can be placed from bottom to top, and the dehumidifier 200 can be installed in the gap between the top of the battery and the top wall to make full use of the internal space of the cabinet 101.

[0108] In some examples, the cabinet 101 further includes a bracket 107, and the shell is connected to the bracket 107. The bracket 107 serves as an intermediate connector between the inner wall of the cabinet 101 and the dehumidifier 200. The bracket 107 can be a strip, L-shaped or other shaped structure connected to the top wall, and the dehumidifier 200 is connected and fixed to the cabinet 101 through the bracket 107. In this example, by setting the bracket 107, it is convenient to match the dehumidifier 200. On the one hand, the preset wall of the dehumidifier 200 can be connected to the cabinet 101. On the other hand, during installation, the position of the dehumidifier 200 relative to the inner wall of the cabinet 101 can be conveniently adjusted so that the dehumidifier 200 can better fit the internal space of the cabinet 101. The bracket 107 in this example can be connected to a side wall of the dehumidifier 200 provided with an air outlet, or the bracket 107 can be connected to other walls of the dehumidifier 200.

[0109] In some examples, the cabinet 101 has a floor drain 106 , and the drain port 233 is connected to the floor drain 106 through a water pipe.

[0110] The floor drain 106 is a functional module for drainage on the cabinet 101. The floor drain 106 can be installed on the side or bottom of the cabinet 101. The floor drain 106 can also be used to connect external pipelines. The water discharged from the drain port 233 can be output to the floor drain 106 through a water pipe, so that the condensed water generated by the dehumidifier 200 can be discharged in a direction. In some examples, the dehumidifier 200 has a water outlet pipe as described in any of the above examples, and the end of the water outlet pipe away from the through hole can be connected to the floor drain 106 through a water pipe.

[0111] See also Figures 1 to 9The present application discloses a dehumidifier 200, which includes a housing 210, a dehumidification assembly 220 and a drain groove 230 disposed in the housing 210. The housing 210 is provided with an air inlet 215 and an air outlet 216. The humid air flow enters the housing 210 through the air inlet 215. The dehumidification assembly 220 is disposed above the drain groove 230. The dehumidification assembly 220 is used to dehumidify the humid air flow. The dry air flow formed after dehumidification is output to the outside of the housing 210 through the air outlet 216. The drain groove 230 is used to receive the condensed water generated by the dehumidification assembly 220. The drain groove 230 has a drain outlet 233. The drain outlet 233 of the drain groove 230 is disposed toward the air outlet 216, or the drain outlet 233 of the drain groove 230 is disposed toward the air inlet 215. The drainage groove 230 in the example of the present application has a bottom wall 231 and a side wall 232, and the top of the bottom wall 231 has an opening for receiving condensed water, so that the condensed water generated by the dehumidification component 220 can enter the drainage groove 230. In this example, the drainage port 233 can be set on the side wall 232 of the drainage groove 230, and the drainage port 233 can be extended to the bottom wall 231 of the drainage groove 230, so that the condensed water entering the drainage groove 230 can be discharged as much as possible, thereby reducing the problem of secondary evaporation of accumulated water. The dehumidification component 220 in this example can use a semiconductor cooling plate, which has a first end 221 and a second end 222, wherein the lower end of the first end 221 is embedded in the drainage groove 230 to reduce the possibility of splashing when the condensed water on the first end 221 drips; in this example, the lower end of the first end 221 can be in a state of gradually narrowing width, so that the lower end of the first end 221 forms an inclined surface, and the condensed water is guided through the inclined surface on the first end 221. In this example, a guide slope can be provided on the bottom wall 231 of the drainage groove 230, and the condensed water can be guided toward the drainage port 233 through the guide slope, so that the water in the drainage groove 230 can be discharged as much as possible, and the water accumulation in the drainage groove 230 can be reduced. The dehumidifier 200 in this example can be used in electrical equipment 100 such as an electric cabinet, and since the thickness of the dehumidifier 200 can be reduced, the dehumidifier 200 can be installed on the top wall of the electric cabinet to make full use of the narrow space at the top wall of the electric cabinet.
