[0020] Please refer to Figures 1-4 , an embodiment provided by the present utility model: an electric control cabinet with a dehumidification function, including an electric control cabinet main body 1, an air pump 4, and an intake pipe 5 and an outlet pipe 6 respectively arranged at the inlet and outlet of the air pump 4. The inside of the electric control cabinet main body 1 is divided into two independent chambers, a first chamber 101 and a second chamber 102, by a partition 2. The first chamber 101 is used for installing electrical components, and movable doors 3 are hingedly arranged on the front end faces of both the first chamber 101 and the second chamber 102.

[0021] The air pump 4, the intake pipe 5, and the outlet pipe 6 are all arranged inside the second chamber 102. A reversible desiccant is placed inside the intake pipe 5. A heating jacket 7 is arranged outside the intake pipe 5. One end of the intake pipe 5 away from the air pump 4 is provided with a movable cover 503 through threads or a flange, so that the reversible desiccant inside the intake pipe 5 can be replaced. The reversible desiccant can specifically be a silica gel desiccant. A heating resistance wire can specifically be arranged inside the heating jacket 7 to heat and dry the reversible desiccant for reuse, reducing the cumbersome process of frequently replacing the desiccant;

[0022] The intake pipe 5 is provided with a first intake branch pipe 501 and a second intake branch pipe 502 that are respectively communicated with the first chamber 101 and the outside. The outlet pipe 6 is provided with a first outlet branch pipe 601 and a second outlet branch pipe 602 that are respectively communicated with the first chamber 101 and the outside. The first intake branch pipe 501 is vertically arranged at the top of the intake pipe 5. The second intake branch pipe 502 is horizontally arranged on one side of the intake pipe 5. The first outlet branch pipe 601 is vertically arranged at the top of the outlet pipe 6. The second outlet branch pipe 602 is horizontally arranged on one side of the outlet pipe 6. The partition 2 is provided with a first through hole 201 communicated with the first intake branch pipe 501 and a second through hole 202 communicated with the second outlet branch pipe 602. The back surface of the second chamber 102 is provided with a third through hole 1021 communicated with the second intake branch pipe 502 and a fourth through hole 1022 communicated with the second outlet branch pipe 602. By simultaneously opening the first intake branch pipe 501, the first outlet branch pipe 601, the first through hole 201, and the second through hole 202, the first chamber 101 and the second chamber 102 can be communicated, reducing the air humidity inside the electric control cabinet and avoiding damage to the internal electrical components. By simultaneously opening the first outlet branch pipe 601, the second outlet branch pipe 602, the third through hole 1021, and the fourth through hole 1022 and closing the first intake branch pipe 501, the first outlet branch pipe 601, the first through hole 201, and the second through hole 202, the second chamber 102 can be communicated with the outside air of the electric control cabinet, facilitating the heating and drying of the reversible desiccant and preventing water vapor from being discharged back into the first chamber 101;

[0023] On both sides inside the second chamber 102, a first baffle 8 and a second baffle 9 are respectively arranged. An adjusting mechanism 10 for adjusting the positions of the first baffle 8 and the second baffle 9 is arranged inside the second chamber 102. The first baffle 8 is used to control the alternating switching of the first intake branch pipe 501 and the second intake branch pipe 502. The second baffle 9 is used to control the alternating switching of the first outlet branch pipe 601 and the second outlet branch pipe 602. The first baffle 8 and the second baffle 9 have the same structure and include a horizontal section closely attached to the bottom end of the partition 2 and a vertical section closely attached to the back surface of the inner side wall of the second chamber 102. When the first baffle 8 moves to coincide with the first intake branch pipe 501 and the first through hole 201, the second intake branch pipe 502 and the fourth through hole 1022 are opened, and the first intake branch pipe 501 and the first through hole 201 are closed. When the first baffle 8 moves to coincide with the second intake branch pipe 502 and the third through hole 1021, the first intake branch pipe 501 and the first through hole 201 are opened, and the second intake branch pipe 502 and the third through hole 1021 are closed. When the second baffle 9 moves to coincide with the first outlet branch pipe 601 and the second through hole 202, the second outlet branch pipe 602 and the fourth through hole 1022 are opened, and the first outlet branch pipe 601 and the second through hole 202 are closed. When the second baffle 9 moves to coincide with the second outlet branch pipe 602 and the fourth through hole 1022, the first outlet branch pipe 601 and the second through hole 202 are opened, and the second outlet branch pipe 602 and the fourth through hole 1022 are closed.

[0024] Specifically, the adjusting mechanism 10 includes a threaded rod 1001 horizontally arranged inside the second chamber 102 and a motor 1002 for driving the threaded rod 1001 to rotate. In this embodiment, the external threads at both ends of the threaded rod 1001 are opposite. Both the first baffle 8 and the second baffle 9 are threadedly connected to both ends of the threaded rod 1001 through sliders. By driving the threaded rod 1001 to rotate through the motor 1002, the first baffle 8 and the second baffle 9 can be driven to move in the same speed and in opposite directions. The first baffle 8 and the second baffle 9 are symmetrically arranged inside the second chamber 102. When the motor 1002 rotates, the first baffle 8 and the second baffle 9 move towards the middle or towards both sides simultaneously.

[0025] A humidity sensor and a controller are installed inside the first chamber 101. The output end of the humidity sensor is connected to the input end of the controller. The output end of the controller is connected to the input ends of the heating jacket 7, the motor 1002 and the air pump 4. The humidity sensor detects the humidity inside the electric control cabinet in real time. When the humidity is too high, the controller turns on the switch of the air pump 4 to pump the gas inside the first chamber 101 into the intake pipe 5 for moisture absorption. After working for a period of time, if the humidity is still too high, the motor 1002 and the heating jacket 7 are turned on to heat and dry the reversible desiccant, realizing intelligent control.

[0026] Working principle: During operation, the first baffle 8 moves to one side of the second intake branch pipe 502 to block and seal the second intake branch pipe 502 and the third through hole 1021, and the second baffle 9 moves to one side of the second exhaust branch pipe 602 to block and seal the second exhaust branch pipe 602 and the fourth through hole 1022. The air pump 4 pumps the air inside the first chamber 101 into the inside of the intake pipe 5 through the first through hole 201 and the first intake branch pipe 501. After being absorbed by the reversible desiccant inside, it is discharged through the outlet pipe 6, the first exhaust branch pipe 601 and the second through hole 202. When the reversible desiccant inside the intake pipe 5 reaches saturation, the switches of the heating jacket 7 and the motor 1002 are turned on. The motor 1002 drives the threaded rod 1001 to rotate, causing the first baffle 8 and the second baffle 9 to move to both sides simultaneously. The top of the first baffle 8 abuts against the first intake branch pipe 501 and the first through hole 201, and the top of the second baffle 9 abuts against the first exhaust branch pipe 601 and the second through hole 202. The water vapor evaporated by heating the desiccant inside the intake pipe 5 is discharged to the outside through the second intake branch pipe 502. At the same time, turning on the air pump 4 can also assist the flow of air and accelerate the drying of the desiccant.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
