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 airflow condenses on the cooling plate of the dehumidifier to form condensed water, which is then stored in the water tank. Since the water in the water tank is easily condensed on the cooling plate after evaporation, it is easy to cause corrosion of the dehumidifier components. Utility Model Content

[0003] The present application provides a dehumidifier and an electrical device, aiming to improve the problem that condensed water of the dehumidifier easily enters the dehumidification component and causes corrosion of the dehumidification component.

[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 disposed in the housing, and the dehumidification component is located between the air inlet and the air outlet; and

[0007] A drainage groove is connected to the shell and is arranged below the dehumidification component to receive condensed water generated by the dehumidification component;

[0008] The drainage groove has a bottom wall facing the dehumidification component and a side wall arranged at the periphery of the bottom wall. The drainage groove is provided with an opening for receiving condensed water generated by the dehumidification component, and a drainage port is provided on the side wall of the drainage groove.

[0009] In the example of the present application, a drainage trough is provided below the dehumidification component, and the condensed water generated by the dehumidification component directly enters the drainage trough through the opening of the drainage trough; by providing a drain port on the drainage trough, the condensed water on the dehumidification component is directly discharged through the drain port of the drainage trough, and there is no need to additionally provide a water tank for storing water, thereby reducing the problem of secondary condensation on the dehumidification component after water evaporates due to water storage in the water tank; in this example, due to the opening on the side wall of the drainage trough, the water can be drained from the side, thereby reducing the space required for the height of the drainage trough.

[0010] 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.

[0011] The side wall includes a first side wall and a second side wall that are arranged opposite to each other, and a drain 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 drain 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 water can be diverted in the direction of the drain port of the water tank, thereby reducing the accumulation of condensed water in the drainage groove, 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.

[0012] The drain groove is arranged in the shell, and a first through hole is opened on the shell, and the first through hole is 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.

[0013] Among them, a water outlet pipe is connected between the drain port and the first through hole. In this example, by setting the water outlet pipe, the water in the drain groove can be guided to a preset direction through the water outlet pipe; because the drain port and the first through hole are connected by the water outlet pipe, the installation position of the drain groove can be more diverse, and the drain groove can be better adapted to the position of the dehumidification component as needed.

[0014] 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 first through hole is opened in the first vertical wall. In this example, by arranging the first through hole on the first vertical wall, the dehumidifier can discharge water from the side, thereby reducing the overall thickness of the dehumidifier.

[0015] The air inlet is arranged on the first vertical wall. In this example, by arranging the air inlet on the first vertical wall, the dehumidifier can be aired from the side, and the dehumidifier can be installed in the top gap in the cabinet of the electrical equipment, thereby reducing the space occupancy rate of the dehumidifier.

[0016] The housing further comprises a second vertical wall which is staggered with the first vertical wall, and at least one of the second vertical wall, the upper wall and the lower wall is provided with an air outlet. In this example, by providing the air outlet on at least one of the second vertical wall, the upper wall and the lower wall of the housing, on the one hand, the positions of the air outlet and the air inlet can be staggered with each other, and on the other hand, the wind direction of the air outlet can be controlled as needed, so that the dehumidifier can be better adapted to the electrical equipment.

[0017] One of the dehumidification component and the drainage groove is provided with a positioning groove, and the other is provided with a clamping part, which is clamped in the positioning groove. In this example, by using the clamping part and the positioning groove to cooperate, the dehumidification component and the drainage groove can be easily positioned relative to each other to improve the installation efficiency of the two.

[0018] Wherein, the dehumidification component is a semiconductor refrigeration sheet; the semiconductor refrigeration sheet has a first end and a second end; the semiconductor refrigeration sheet has a first end and a second end;

[0019] 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 a semiconductor cooling sheet, the first end can be used to dehumidify the wet air flow, and the second end can be used to heat the dry air flow delivered to the air outlet, which can reduce the overall volume of the dehumidification component, 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.

[0020] The first end 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, it helps to reduce the possibility of splashing when the condensed water at the first end drips.

[0021] The first end has a first portion close to the drainage groove and a second portion away from the drainage groove, and the cross-sectional area of ​​the first portion of the first end gradually decreases from the second portion of the first end toward the first portion. In this example, by gradually reducing the cross-sectional area of ​​the first portion of the first end, the condensed water can be diverted so that the condensed water on the first end gradually gathers toward the second portion, and the gathered condensed water can enter the drainage groove along the first end to reduce the possibility of the condensed water dripping outside the drainage groove.

[0022] Among them, the dehumidifier also includes:

[0023] 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.

[0024] 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.

[0025] 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.

[0026] The partition is provided with a second via hole connecting the first cavity and the second cavity, the electrical component is electrically connected to the dehumidification component through a connector penetrating the second via hole, and a seal is provided between the connector and the inner wall of the second via hole. In this example, by providing the second via hole on the partition, the wiring of the electrical component and the dehumidification component can be facilitated; by providing the seal, the possibility of water vapor in the second cavity entering the first cavity can be reduced, thereby helping to improve the moisture-proof performance of the electrical component in the first cavity.

[0027] 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.

[0028] Among them, the dehumidifier also includes:

[0029] The fan is arranged at the air outlet and is electrically connected to the electrical component. In this example, by arranging the fan, the air flow rate can be increased to improve the dehumidification efficiency.

[0030] The present application also proposes an example of an electrical device, including:

[0031] Cabinets; and

[0032] A dehumidifier as described in any of the above examples is connected to a cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] 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.

[0045] 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.

[0046] 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.

[0047] The multiple terms in the examples of this application refer to at least two (including two).

[0048] 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.

[0049] 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, making it difficult to install the dehumidification equipment directly inside the electric cabinet for dehumidification.

[0050] 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; the drain groove has a bottom wall facing the dehumidification component and a side wall arranged at the periphery of the bottom wall, the drain groove is provided with an opening for receiving condensed water generated by the dehumidification component, and a drain outlet is provided on the side wall of the drain groove. 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 drain 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 additional water storage structures such as water tanks, thereby reducing the overall size of the dehumidifier. In the example of the present application, the side wall of the drainage trough is used for drainage. When installing the dehumidifier, it is not necessary to reserve too much space under the drainage trough. Therefore, the space required for the drainage trough in the height direction can be reduced, so as to further reduce the space occupancy rate of the dehumidifier, thereby enabling the dehumidifier to make full use of the narrow space on the top of the electrical cabinet.

[0051] See also Figure 1The dehumidifier in the example of the present application can be used for the electrical equipment 100, and the electrical equipment 100 in the example of the present application can be an electrical cabinet or other electrical equipment 100. In the present application, by reducing the thickness of the dehumidifier 200, the dehumidifier 200 can be installed on the top of the cabinet 101, so that the dehumidifier 200 can make full use of the narrow space on the top of the cabinet 101, thereby improving the space utilization rate in the cabinet 101.

[0052] See also Figure 2 , Figure 3 and Figure 4 The present application discloses an example of a dehumidifier 200, including 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; the drain groove 230 has a bottom wall 231 facing the dehumidification component 220 and a side wall 232 arranged on the periphery of the bottom wall 231, the drain groove 230 is provided with an opening 236 for receiving condensed water generated by the dehumidification component 220, and a drain outlet 233 is provided on the side wall 232 of the drain groove 230.

[0053] The housing 210 is at least partially hollow, and an inner cavity is formed inside the housing 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 housing 210, and the air inlet 215 and the air outlet 216 are respectively connected to the inner cavity of the housing 210, and the air flow can enter the housing 210 from the air inlet 215 and be output from the air outlet 216.

[0054] Please refer to Figure 5 and Figure 6, 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.

[0055] Please refer to Figure 7 and Figure 8The drain trough 230 is installed below the dehumidification component 220 to receive the condensed water generated by the dehumidification component 220. When the dehumidifier is in use, the side of the dehumidification component 220 facing the ground is the bottom of the dehumidification component, and the condensed water generated on the dehumidification component 220 can flow from top to bottom under the action of gravity; the side of the drain trough 230 facing away from the ground is the top of the drain trough, and the side of the drain trough facing the ground is the bottom of the drain trough. The drain trough 230 has an opening 236 for receiving the condensed water generated by the dehumidification component, and the condensed water on the dehumidification component above the drain trough can flow downward into the drain trough through the opening 236 on the drain trough 230; the opening 236 is set corresponding to the dehumidification component so that the condensed water generated on the dehumidification component can enter the inside of the drain trough; the opening 236 in this example can be set offset from the bottom wall of the drain trough. The water receiving trough has a bottom wall 231 and a side wall 232, wherein the side wall 232 is connected to the periphery of the bottom wall 231 and extends toward the dehumidification component. In this example, the end of the side wall 232 away from the ground can be enclosed to form an opening 236 for receiving condensed water, and the opening 236 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 236; the side wall 232 in this example can be enclosed at 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, etc.; optionally, the drainage trough 230 can have a top wall arranged opposite to the bottom wall, and the top wall is arranged on the side of the bottom wall 231 away from the ground, and the opening 236 can be opened on the top wall; optionally, the opening 236 can be opened on the side wall 232 so that the condensed water generated by the dehumidification component can enter the drainage trough through the opening 236. 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 drain groove 230 can be arranged below the fins or condensation tubes so that the drain groove 230 can receive condensed water. Optionally, the drain groove 230 in this example can be connected to the dehumidification component 220 so that the opening 236 of the drain groove 230 can be arranged corresponding to the dehumidification component 220, and the condensed water generated by the dehumidification component 220 can be directly dripped into the drain groove 230. In this example, the water received by the drain groove 230 is directly discharged from the outside of the dehumidifier 200, and there is no need to set up an additional water tank, thereby reducing the thickness of the dehumidifier 200, so that the dehumidifier 200 can make full use of the narrow installation space. In this example, the condensed water is directly discharged from the drain port 233, and the dehumidifier 200 does not use a water tank to store condensed water, thereby reducing the problem of secondary condensation of water vapor caused by water evaporation in the water tank. Since the condensed water is discharged from the side wall 232 of the drain groove 230 in this example, the drainage does not need to occupy the space at the bottom of the drain groove 230, which can facilitate reducing the height of the drain groove 230 and further reduce the thickness of the dehumidifier 200.The drain port 233 in this example can be disposed at any position of the side wall 232 of the drain groove 230, or at a position close to the middle in the length direction of the drain groove 230. The housing 210 of the dehumidifier 200 in this example can be a rectangular parallelepiped structure as a whole. Figure 3 For example, the first direction 3a may be the height direction of the dehumidifier 200, the second direction 3b may be the length direction of the dehumidifier 200, and the third direction 3c may be the front-to-back width 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 3a.

[0056] In some examples, a drain port 233 is provided on the side wall 232 of the drain groove 230, and 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, thereby reducing the accumulation of water in the drain groove 230 and further reducing the secondary evaporation of water in the drain groove 230.

[0057] 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.

[0058] In some examples, in order to accelerate the flow of air, a fan 250 may be provided inside or outside the dehumidifier so that the air can flow from the air inlet to the air outlet. The fan 250 in this example may be provided inside the housing, or outside the housing.

[0059] See also Figure 7 and Figure 8 In some examples, the side wall 232 of the drainage groove 230 includes a first side wall 2321 and a second side wall 2322 that are arranged opposite to each other, and a drainage port 233 is opened 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.

[0060] In this example, the first side wall 2321 may be the front wall of the drainage groove 230 or other wall surfaces. The second side wall 2322 is staggered with the first side wall 2321 , and the drainage port 233 is disposed on the first side wall 2321 .

[0061] 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 condensed water toward the drain outlet, and the condensed water entering the drain groove 230 can flow toward the drain outlet 233 along the diversion slope. 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 3a, 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.

[0062] See also Figure 3 and Figure 4 In some examples, the drain groove 230 is provided in the housing 210, and a first through hole 2131 is provided on the housing 210, and the first through hole 2131 is connected to the drain port 233. In this example, the drain groove 230 is integrated in the housing 210 so that the drain groove 230 can make full use of the internal space of the housing 210. The first through hole 2131 is provided through the housing 210 to connect the inner cavity of the housing 210, and the drain port 233 is connected to the first through hole 2131 so that the condensed water outputted from the drain port 233 can be outputted to the outside of the dehumidifier 200 along the first through hole 2131. Since the drain groove 230 can be integrated in the housing 210, on the one hand, it is not necessary to provide a through hole connected to the drain groove 230 on the lower wall 212 of the housing 210, which can reduce the processing flow of the housing 210; on the other hand, the lower wall 212 of the housing 210 can be kept relatively flat, so that the dehumidifier 200 can better adapt to the narrow space inside the electrical device 100.

[0063] In some examples, a water outlet pipe 235 is connected between the drain port 233 and the first through hole 2131. The water outlet pipe 235 in this example can be a straight pipe, or a curved pipe. In this example, by connecting the drain port 233 and the first through hole 2131 through the water outlet pipe 235, a certain deformable space is provided between the drain groove 230 and the wall surface of the housing 210 on which the first through hole 2131 is provided, and the drain groove 230 can be installed at any position in the housing 210, so as to improve the convenience of assembling the drain groove 230 and the dehumidification assembly 220 in the housing 210.

[0064] 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 a first through hole 2131 is opened on the first vertical wall 213. The first vertical wall 213 in this example can be a wall surface on the front side or other orientation of the housing 210. The first vertical wall 213 can be arranged perpendicular to the horizontal plane, and the first vertical wall 213 can also be arranged at an inclination relative to the horizontal plane. In this example, by opening the first through hole 2131 on the first vertical wall 213, the upper wall 211 and the lower wall 212 of the housing 210 can be avoided, so that the portion of the housing 210 for water outlet is located on the side of the housing 210, and when the dehumidifier 200 is installed, the space required for the housing 210 in the height direction can be reduced.

[0065] In some examples, the air inlet 215 is provided on the first vertical wall 213. In this example, by taking in air from the first vertical wall 213, when the dehumidifier 200 is installed in a relatively narrow space such as the top of an electric cabinet, the dehumidifier 200 can take in air from the side, thereby reducing the space required for the dehumidifier 200 in the height direction.

[0066] In some examples, the housing 210 further has a second vertical wall 214 disposed offset from the first vertical wall 213, and at least one of the second vertical wall 214, the upper wall 211, and the lower wall 212 is provided with an air outlet 216. In this example, dry air generated after dehumidification by the dehumidification assembly 220 can be output from the air outlet 216.

[0067] The second vertical wall 214 and the first vertical wall 213 are staggered, 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 arranged along the same plane as the first vertical wall 213. Figure 3 The second vertical wall 214 may be a wall surface opposite to the first vertical wall 213 in the second direction 3 b .

[0068] In this example, an air outlet 216 connected to the inner cavity of the shell 210 can be set only on the second vertical wall 214, and 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, and the dry air flow can be output through the air outlet 216 on the second vertical wall 214. In this example, the air outlet 216 can also be set on the upper wall 211 or the lower wall 212, so that the upper wall 211 or the lower wall 212 is used to output the dry air flow. Optionally, in some examples, the air outlet 216 is set on the second vertical wall 214, the upper wall 211 and the lower wall 212, so that the dehumidifier 200 forms a structure in which the air enters from one side of the first vertical wall 213, and the air is discharged from three directions of the second vertical wall 214, the upper wall 211 and the lower wall 212, so as to speed up the air flow output speed and improve the dehumidification efficiency.

[0069] Please refer to Figures 5 to 9 In some examples, one of the dehumidification component 220 and the drainage groove 230 is provided with a positioning groove 223, and the other is provided with a clamping portion 234, and the clamping portion 234 is clamped in the positioning groove 223. In this example, the clamping portion 234 is clamped in the positioning groove 223, so that the dehumidification component 220 and the drainage groove 230 are mutually clamped, and the relative movement of the dehumidification component 220 and the drainage groove 230 can be restricted. When the dehumidification component 220 and the drainage groove 230 are installed, the dehumidification component 220 can be positioned by the cooperation of the clamping portion 234 and the positioning groove 223, so as to facilitate the subsequent fixing of the dehumidification component 220. In this example, the clamping portion 234 can be provided on the drainage groove 230, and the positioning groove 223 can be provided on the dehumidification component 220; the clamping portion 234 can also be provided on the dehumidification component 220, and the clamping portion 234 is provided on the drainage groove 230, and the clamping portion 234 and the positioning groove 223 are mutually clamped. In some examples, the positioning groove 223 may be provided at the lower end of the dehumidification component 220, and the dehumidification component 220 may be clamped on the clamping portion 234 on the drainage groove 230 from top to bottom, so that the dehumidification component 220 and the drainage groove 230 are installed in the up-down direction. Optionally, the clamping portion 234 may be a convex block, a convex rib or a rib provided on the drainage groove 230, and the clamping portion 234 may also be a protruding structure formed by partially protruding the side wall 232 of the drainage groove 230.

[0070] See also Figure 5 , Figure 6 as well as Fig. 9 In some examples, the dehumidification component 220 is a semiconductor refrigeration plate; the semiconductor refrigeration plate 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.

[0071] The semiconductor cooling sheet has a first end 221, and the first end 221 is used for heat exchange with the wet air flow. The water vapor in the wet air flow can be condensed on the first end 221 to form condensed water, so as to remove the water vapor in the air flow and form a dry air flow. In this example, the first end 221 can be a long sheet structure, and the first end 221 can be along the Figure 3 The drain groove 230 is extended in the first direction 3 a so that the condensed water on the first end 221 can flow along the first end 221 toward the drain groove 230 .

[0072] 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.

[0073] 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 3a can be reduced, thereby helping to reduce the overall thickness of the dehumidifier. 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.

[0074] Please refer to 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 cross-sectional area 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 3 The second part 2212 can be arranged at one end in the first direction 3a 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 3a. 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 cross-sectional area 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 to the guide slope position along the slope formed on the first part 2211 to reduce the possibility of the condensed water splashing out of the drain groove 230.

[0075] 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, for controlling the operation of the dehumidification component 220. The electrical component 240 is installed on the housing 210 and 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 operating 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 reaches 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 can also include other functional modules.

[0076] 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 wet air flow, 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 housing 210 into two cavities, and the connection between the partition 217 and the inner wall of the housing 210 can be sealed with a sealing gasket or other structure to improve the moisture-proof performance of the electrical component 240.

[0077] In some examples, the dehumidification component 220 and the drainage groove 230 are arranged along the first direction 3a, the first cavity 218 and the second cavity 219 are arranged at intervals along the second direction 3b, and the first direction 3a and the second direction 3b are arranged at an angle. The dehumidification component 220 and the drainage groove 230 in this example can be arranged along the thickness direction of the dehumidifier 200, and the first cavity 218 and the second cavity 219 are arranged at intervals along the second direction 3b. The first direction 3a and the second direction 3b are arranged at an angle, which means that the first direction 3a and the second direction 3b are not parallel. Optionally, in this example, the second direction 3b can be arranged perpendicular to the first direction 3a. Since the first cavity 218 and the second cavity 219 are arranged at intervals along the second direction 3b, the space occupied by the electrical component 240 in the thickness 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.

[0078] See also Figure 3 and Figure 4 In some examples, a second through hole 2171 connecting the first cavity 218 and the second cavity 219 is provided on the partition 217, and the electrical component 240 is electrically connected to the dehumidification component 220 through the connector 241 penetrating the second through hole 2171, and a sealing member 242 is provided between the connector 241 and the inner wall surface of the second through hole 2171. In this example, by providing the second through hole 2171, the length of the connector 241 between the electrical component 240 and the dehumidification component 220 can be shortened to facilitate the nearby connection of the electrical component 240 and the dehumidification component 220. The sealing member 242 in this example can be a sealing ring sleeved on the periphery of the connector 241 or other sealing structure that can play a sealing role. The connector 241 in this example can be a wire or other structure that can play an electrical connection.

[0079] In some examples, the housing 210 is provided with a socket assembly 243, and the electrical assembly 240 is electrically connected to the socket assembly 243. In this example, by providing the socket assembly 243, the electrical assembly 240 and the socket assembly 243 can be conveniently connected quickly, and the electrical assembly 240 in this example can be plugged into the socket assembly 243. The socket assembly 243 can also be used to connect structures such as an external power supply. The socket assembly 243 in this example can be an aviation plug, or it can be other socket structures that can make electrical connections.

[0080] 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 the air outlet 216, or the fan 250 can 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.

[0081] Based on the above-mentioned dehumidifier 200, the present application also proposes an example of an electrical device 100, including a cabinet 101 and a dehumidifier 200 as described in any of the above-mentioned examples, and the dehumidifier 200 is connected to the cabinet 101. The dehumidifier 200 in this example can be arranged in the cabinet 101 to circulate and dehumidify the gas in the cabinet 101; optionally, the dehumidifier 200 in this example can also be installed outside the cabinet 101, and the air outlet of the dehumidifier 200 is connected to the inside of the cabinet 101, which is used to transport dry airflow to the inside of the cabinet 101, thereby reducing the humidity inside the cabinet 101. The drain port 233 of the dehumidifier 200 in this example can be set toward the cabinet door of the cabinet. The cabinet 101 in this example can be used to place equipment such as batteries. Taking the electrical device 100 as an electric cabinet for storing batteries as an example, the dehumidifier 200 is optionally arranged on the top of the cabinet 101 to make full use of the space above the battery. Since the water can be discharged from the side of the drainage groove 230 in the example of the present application, on the one hand, the thickness of the drainage groove 230 can be conveniently reduced, thereby making full use of the narrow space above the battery. On the other hand, the drainage structure of the dehumidifier can be conveniently staggered with the battery arranged below to improve the reliability of the electrical equipment.

[0082] Please refer to Figures 1 to 9The example of the present application discloses a dehumidifier 200, which includes a housing 210, a dehumidification component 220 and a drainage 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 component 220 is disposed above the drainage groove 230. The dehumidification component 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 drainage groove 230 is used to receive the condensed water generated by the dehumidification component 220. The drainage groove 230 in the example of the present application has a bottom wall 231 and a side wall 232. The top of the bottom wall 231 has an opening for receiving the condensed water, so that the condensed water generated by the dehumidification component 220 can enter the drainage groove 230. In this example, a drain port 233 is provided on the side wall 232 of the drain groove 230, and the drain port 233 extends to the bottom wall 231 of the drain groove 230, so that the condensed water entering the drain groove 230 can be discharged as much as possible, thereby reducing the problem of secondary evaporation of the accumulated water. The dehumidification component 220 in this example can use a semiconductor refrigeration 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 drain groove 230 to reduce the possibility of splashing when the condensed water on the first end 221 drops; in this example, the lower end of the first end 221 can be in a state of gradually reducing the cross-sectional area, so that the lower end of the first end 221 forms an inclined surface, and the condensed water is guided by the inclined surface on the first end 221. In this example, a guiding inclined surface can be provided on the bottom wall 231 of the drain groove 230, and the condensed water is guided to the drain port 233 by the guiding inclined surface, so that the water in the drain groove 230 can be discharged as much as possible, and the accumulated water in the drain groove 230 can be reduced. The dehumidifier 200 in this example can be used in electrical equipment 100 such as an electrical cabinet. Since the thickness of the dehumidifier 200 can be reduced, the dehumidifier 200 can be installed on the top wall of the electrical cabinet to fully utilize the narrow space at the top wall of the electrical cabinet.
