[0049] To further improve the present utility model, on the basis of the above improvements, it further includes:

[0050] The size of the drying chamber body 10 is 7000x3200x1800. The air suction duct 202 and the air outlet duct 204 are made of galvanized material, and a layer of heat insulation material is wrapped on their outer walls. The electric fresh air louver 103 is located at the upper section of the side wall surface of the drying chamber body 10. The air suction duct 202 is located at the lower section of the side wall surface of the drying chamber body 10. The air outlet duct 204 is located at the upper section of the side wall surface of the drying chamber body 10. The ventilation fan 205 is located on the top surface of the drying chamber body 10 away from the electromechanical equipment 20. A door lock is provided on the double-opening door 102. The door lock adopts a 1178 door lock (including a safety inward-opening push rod), which can be opened with a single push, and can avoid the risk of personnel's life in case of emergency.

[0051] In addition, in order to strengthen the balance of heat on the left and right sides inside the drying chamber body 10, the air outlet duct 204 on the left side can be communicated with the air outlet duct 204 on the right side.

[0052] Working principle:

[0053] As Figure 5 shown, the vacuum product 30 is placed on the trolley 301, and the trolley 301 pushes the vacuum product 30 into the drying space inside the drying chamber body 10.

[0054] Close the double-opening door 102. The temperature sensor detects the temperature value inside the drying chamber body 10 and feeds the temperature value back to the controller. A temperature value range that actually needs to be heated is preset in the controller. The controller compares the temperature value inside the drying chamber body 10 detected by the temperature sensor with the preset temperature value range in the controller.

[0055] After heating for a period of time (for example, 25 minutes), when the temperature value inside the drying chamber body 10 detected by the temperature sensor is lower than the preset temperature value range in the controller (referring to that the temperature value inside the drying chamber body 10 detected by the temperature sensor is lower than the minimum value of the preset temperature value range in the controller), the controller issues a control signal to start the electric heater 201 and the centrifugal fan 203 to heat the internal temperature of the entire drying chamber body 10.

[0056] When the temperature value inside the drying chamber body 10 detected by the temperature sensor is within the temperature value range preset in the controller, adjust the heating temperature of the electric heater 201 so that the temperature is maintained within the temperature value range preset in the controller, and the air discharge fan 203 remains in the on state, thereby realizing the cyclic heating and utilization of hot air.

[0057] When the temperature value inside the drying chamber body 10 detected by the temperature sensor is greater than the temperature value range preset in the controller but still below the preset maximum critical value (it means that the temperature value inside the drying chamber body 10 detected by the temperature sensor is greater than the maximum value of the temperature value range preset in the controller), at this time, turn off the electric heater 201, the air discharge fan 203 can remain in the on state, and at the same time, turn on the electric fresh air shutter 103 and the ventilation fan 205 to reduce the temperature inside the drying chamber body 10 until the temperature value inside the drying chamber body 10 detected by the temperature sensor is within the temperature value range preset in the controller, then turn off the electric fresh air shutter 103 and the ventilation fan 205.

[0058] When the temperature value inside the drying chamber body 10 detected by the temperature sensor is greater than the temperature value range preset in the controller and greater than the preset maximum critical value of the controller, turn off the electric heater 201, the air discharge fan 203 can remain in the on state, turn on the electric fresh air shutter 103 and the ventilation fan 205, and at the same time the controller issues an alarm signal, and the alarm gives an alarm, indicating that the temperature is abnormal.

[0059] Among them, the power regulating transformer adjusts the power output to adapt to the load change. The power regulating transformer can control the current or power so that the equipment can work normally under different load conditions, which is an existing mature technology; the temperature value range preset in the controller can be displayed on the display screen (for example, 120°C to 130°C); the timing device can set the heating time of the vacuum product 30 (for example, 2 days); during the heating of the vacuum product 30, the timing device sets the heating time (for example, from a certain date to a certain date, this Saturday to next Monday, or two days). After the time set by the timing device is up, the controller receives the feedback from the timing device, and the controller sends a control signal to the reminder device to remind the staff that the heating time is up and automatically shut down the machine.

[0060] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
