[0037] As discussed in the previous background technology, the problems faced by the drying box are: the temperature distribution in the drying chamber is uneven, causing the product to be heated unevenly in the drying box, or overheated or insufficiently heated, or locally overheated, and the existing technology for temperature control of the drying box cannot achieve uniform heating.

[0038] To this end, the concept of the utility model is to set a drying chamber in a drying box, and ensure that the temperature in the entire drying chamber remains consistent by allowing heating elements arranged at different positions in the drying chamber to be at least partially activated and closed. At the same time, a hot and cold circulation system is set, that is, a condensing device is set at different positions of the drying box and an air inlet and an air outlet are set on the drying chamber.

Figure 1 As shown, the drying box 100 dries the processed objects to produce the final objects, and the processed objects may include the bushings of transformers, wall bushings, mutual inductors and other electrical components that need to be dried during processing. The drying box 100 may include: a box body 10 and a drying chamber 20 disposed in the box body 10.

[0040] Furthermore, if Figure 2 As shown, the box 10 can be defined by a box wall, and a heat-insulating layer (not shown) can be provided on the box wall to maintain the temperature in the drying chamber. The box wall can include a first box wall 10a located on one side of the box 10 and a second box wall 10b adjacent to the first box wall 10a, the first box wall 10a can be provided with a take-in and put-out opening (not shown) and a closed door (not shown) is hinged on the first box wall 10a to close the take-in and put-out opening, and a plurality of condensing devices 11 are provided at different positions on the inner side of the second box wall 10b, for example, the condensing device 11 can be a commonly used condenser or condensing plate. The box wall can also include a third box wall 10c opposite to the first box wall 10a and a fourth box wall 10d opposite to the second box wall 10b.

[0041] Furthermore, if Figure 3 As shown, the drying chamber 20 is defined by chamber walls, which may include a first chamber wall 20a and a second chamber wall 20b opposite to the first chamber wall 20a, a third chamber wall 20c adjacent to the first chamber wall 20a and the second chamber wall 20b, and a fourth chamber wall 20d opposite to the third chamber wall 20c, and the first chamber wall 20a and the first box wall 10a are located on the same side.

[0042] like Figure 1 As shown, the first chamber wall 20a can be integrated with the first box wall 10a to put the processed objects into the drying chamber 20 and take the processed objects out of the drying chamber 20 through the access port. As an example, the first chamber wall 20a can be a part of the first box wall 10a.

[0043] like Figure 1 As shown, the second chamber wall 20b faces the third box wall 10c and there is a gap between the second chamber wall 20b and the third box wall 10c for air flow.

[0044] like Figure 1As shown, the third chamber wall 20c faces the second box wall 10b and there is a gap between the third chamber wall 20c and the second box wall 10b for air to flow through, and the flowing air is cooled by the condensing device 11 arranged on the second box wall 10b.

[0045] like Figure 1 As shown, the fourth chamber wall 20d faces the fourth box wall 10d and there is a gap between the fourth chamber wall 20d and the fourth box wall 10d for air flow.

[0046] As an example, Figure 1 and Figure 3 As shown, the drying chamber 20 may further include a plurality of heating elements 21 disposed at different positions on the inner side of the second chamber wall 20b. In addition, the third chamber wall 20c may be provided with a plurality of air outlets 22, the fourth chamber wall 20d may be provided with a plurality of first air inlets, and a plurality of fans 23 may be respectively disposed in the plurality of first air inlets.

[0047] In the drying box of the present application, the plurality of heating elements 21 and the plurality of condensing devices 11 can be at least partially activated to maintain a uniform temperature in the drying chamber 20 .

[0048] As an example, Figure 1 and Figure 3 As shown, a plurality of heating elements 21 are arranged on the inner side of the second chamber wall 20b along the height direction z and the length direction x, and a plurality of condensing devices 11 are arranged on the inner side of the second box wall 10b along the height direction z and the width direction y. A plurality of fans 23 are arranged on the fourth chamber wall 20d along the height direction z and the width direction y, and a plurality of air outlets 22 are arranged on the third chamber wall 20c along the height direction z and the width direction y, wherein the plurality of fans 23 and the plurality of air outlets 22 are arranged corresponding to each other, and a plurality of second air inlets 24 can also be provided on the fourth chamber wall 20d, and the plurality of second air inlets 24 can be arranged above the plurality of fans 23 in the height direction z of the box, as shown in FIG. Figure 3 As shown, the present application is not limited thereto. For example, a plurality of second air inlets 24 may be disposed below a plurality of fans 23 in the height direction z of the box, or a plurality of second air inlets may be disposed above and below the box.

[0049] The drying box 100 may further include a plurality of sensors (not shown), which may be disposed at different positions on the inner side of the second chamber wall 20 b. For example, corresponding sensors may be disposed corresponding to the heating element 21 , and the sensors may sense the temperature at different positions within the drying chamber 20 .

[0050] The drying box 100 may also include a controller (not shown), which may be disposed on the outside of the box body 10. The controller may be connected to multiple sensors, multiple heating elements 21, multiple condensing devices 11, and multiple fans 23, and receive sensed temperatures from multiple sensors and control the activation and deactivation of multiple heating elements 21 and multiple condensing devices 11 according to the sensed temperatures, and control the rotation speed of the fans 23 according to the sensed temperatures.

[0051] As an example, the plurality of heating elements 21 arranged in each row along the length direction x and each column along the height direction z and the plurality of condensing devices 11 arranged in each row along the width direction y and each column along the height direction z can be individually activated and deactivated.

[0052] As another example, each of the plurality of heating elements 21 and each of the plurality of condensing devices 11 can be individually activated.

[0053] Specifically, the controller receives sensing signals from sensors arranged at multiple positions, and determines whether the temperature at each position is lower than or higher than a preset temperature based on the received sensing signals. If the temperature is lower than the preset temperature, the controller can turn off the condensing device at the corresponding position and reduce the speed of the fan to increase the temperature at the position. If the temperature is higher than the preset temperature, the controller can turn off the heating element at the corresponding position, enable the condensing device at the corresponding position, and increase the speed of the fan to reduce the temperature at the position, thereby achieving uniform temperature in the drying chamber. For example, the preset temperature can be a set 120 degrees Celsius.

[0054] As an example, when the drying box is initially enabled, each heating element 21 is enabled. During operation, when the controller determines that the temperature of the uppermost part of the drying chamber 20 is higher than the preset temperature based on the sensing signal received from the sensor, the controller turns off the heating elements of the uppermost row in the height direction, turns on the condensing devices of the uppermost row in the height direction, turns on the fan 23 at the uppermost part in the height direction and increases the rotation speed of the fan 23 to the maximum to speed up the circulation of cold air, thereby quickly reducing the temperature of the uppermost part of the drying chamber 20 to the preset temperature.

[0055] The above are only specific examples, and the present application is not limited to the above embodiments.

[0056] In addition, the drying box shown in the drawings of the present application has a rectangular shape, but the present application is not limited to this embodiment. For example, the drying box may be a truncated cylinder shape, etc. Any shape is allowed as long as it can achieve the technical effects of the present application.
