[0025] Please see Figures 1 to 4This invention relates to a microwave drying oven, used for drying wood. The microwave drying oven includes a box body 10 with an opening 11 on one side, a sealing assembly 20 disposed on the opening 11, a pressing assembly 30 mounted on the box body 10 for pressing the wood inside the box body 10, an air venting assembly 40 mounted on the box body 10, and a drying assembly 50 mounted inside the box body 10. The drying assembly 50 includes a fixing member 51 mounted on the outer wall of one side of the box body 10, a drying component 52 mounted on the fixing member 51, and a heat-permeable channel 53 disposed on the drying component 52 relative to the box body 10. The fixing member 51 includes a support plate 510 mounted on the outer wall of one side of the box body 10, and multiple heat dissipation holes 511 disposed on the support plate 510. The drying component 52 is a microwave generator. In this embodiment, the air venting assembly 40 includes an air vent pipe mounted on the top of the box body 10 and communicating with the inside and outside of the box body 10; specifically, there are two air vent pipes.

[0026] The working principle of the microwave drying oven of this utility model is as follows: First, the wood to be dried is placed inside the oven 10 through the opening 11 on one side of the oven 10; after the wood is placed, the opening 11 is sealed with the sealing component 20 to ensure the airtightness of the oven 10 and prevent microwave leakage and the entry of outside air; in order to ensure that the wood remains stable during the drying process and reduce damage caused by the movement of the wood, the wood is pressed by the pressing component 30 installed on the oven 10; after the drying component 52 is started, the microwave generator heat transmission channel 53 acts directly on the wood inside the oven 10; since the moisture in the wood has strong microwave absorption properties, the high temperature can be quickly absorbed by the water molecules, causing the water molecules to be heated and evaporated quickly, thereby achieving the purpose of drying the wood; since the microwave generator is installed on the support plate 510, the microwave generator can also dissipate heat through the heat dissipation holes 511 on the support plate 510 during the heating process inside the oven 10, and at the same time, the air outlet component 40 installed on the oven 10 will continuously discharge the heated moisture inside the oven, further ensuring the drying effect.

[0027] Compared to existing technologies, the microwave drying oven of this invention, through the cooperation of the drying component 52 and the clamping component, ensures the stability of the wood during the drying process, reduces damage caused by wood movement, and improves the drying effect; the sealing component 20 ensures the airtightness of the interior of the oven 10, preventing microwave leakage and the entry of outside air, thus improving safety and drying effect; the heat dissipation holes 511 on the support plate 510 can effectively dissipate heat, preventing the microwave generator from being damaged by overheating and extending the service life of the equipment; by adjusting the clamping component 30 and the air venting component 40, it can adapt to wood of different sizes and shapes, improving the versatility and adaptability of the equipment.

[0028] Please refer to Figure 2 and Figure 3The microwave drying oven also includes a sensing component 60 mounted on a fixing member 51. The sensing component 60 includes a sensor mounted on the fixing member 51 and a sensing channel 62 mounted on the sensor relative to the oven body 10. The sensing component can monitor parameters such as temperature, humidity, and microwave intensity inside the oven body 10 in real time. This data allows for more precise control of the drying process, ensuring the wood dries under optimal conditions. Real-time monitoring allows for timely adjustment of drying parameters, such as microwave intensity and drying time, thereby improving the drying effect. For example, if the sensing component 60 detects a high moisture content in a certain area of ​​the wood, the microwave intensity in that area can be appropriately increased to accelerate the drying speed. Real-time monitoring also helps prevent over-drying of the wood. Over-drying not only wastes energy but can also cause the wood to become brittle and lose strength. The sensing component 60 can adjust parameters in a timely manner to ensure the wood reaches the ideal degree of dryness. The sensing component 60 can also monitor changes in the temperature and humidity of the wood and adjust the pressure of the clamping component 30 in a timely manner, reducing movement and damage to the wood during the drying process. This helps protect the integrity and quality of the wood.

[0029] The sensing components include a temperature sensor 610 mounted on the fixture 51, a humidity sensor 611 mounted on the fixture 51, and a microwave power sensor 612 mounted on the fixture 51. This allows for real-time monitoring of temperature changes inside the chamber 10, ensuring the wood dries within a suitable temperature range. Excessively high or low temperatures can affect drying efficiency and wood quality. Real-time monitoring of humidity inside the chamber 10 helps adjust drying parameters, ensuring the wood dries under optimal humidity conditions and preventing over- or under-drying. Real-time monitoring of microwave power ensures the heating intensity remains within an appropriate range, preventing excessively strong or weak microwaves from negatively impacting the wood. Real-time monitoring and feedback allow for more precise control of the drying process, ensuring the wood is in optimal condition at each stage, thus improving drying efficiency. Sensors detect temperature and humidity at different locations, allowing for timely adjustments to microwave power and the pressure of the clamping assembly 30, ensuring uniform drying both internally and externally, reducing the risk of cracking and deformation. Feedback from temperature and humidity sensors 611 allows for timely adjustment of drying parameters, preventing over-drying and avoiding brittleness and reduced strength. Real-time monitoring can promptly detect and address any abnormalities during the drying process, reducing wood movement and damage, and protecting the integrity and quality of the wood.

[0030] The microwave drying oven also includes a pouring nozzle 70 mounted on a fixing member 51; a spray nozzle 71 is provided on the chamber 10 opposite to the pouring nozzle 70; the pouring nozzle 70 is provided to extend into the chamber 10 from the side of the spray nozzle 71. When the heating element heats the wood, if the wood temperature becomes too high, the temperature sensor 610 transmits a signal to the pouring nozzle 70. The pouring nozzle 70 can then evenly spray liquid onto the surface and interior of the wood. Spraying liquid (such as water or coolant) through the pouring nozzle 70 can quickly lower the wood temperature and prevent damage caused by overheating. Excessive temperature can cause the wood to deform and crack; timely spraying of coolant can reduce these phenomena, protecting the integrity and quality of the wood. Spraying liquid can regulate the internal temperature distribution of the wood, ensuring a more uniform heating process and reducing problems caused by temperature gradients. Overheating of the wood may cause a fire; spraying coolant can effectively prevent fires and improve equipment safety. Excessive temperature can not only damage the wood but also potentially damage the housing 10 and the heating element; spraying coolant can protect the equipment and extend its service life.

[0031] Multiple drying elements 52 are linearly arrayed and mounted on a fixing member 51. Multiple heating channels are also present, each positioned on a corresponding chamber 10. The linear array of drying elements 52 ensures uniform distribution of the wood within the chamber 10, preventing localized concentration and improving drying uniformity. Multiple heating channels, each corresponding to a drying element 52, ensure airflow around each element, preventing localized airflow obstruction and further enhancing drying uniformity. Multiple drying elements 52 can operate simultaneously, providing multi-point microwave heating to accelerate the drying process and improve efficiency. Multiple heating channels accelerate moisture removal, reducing moisture accumulation within the chamber 10 and increasing drying speed. Multi-point heating utilizes microwave energy more effectively, reducing energy waste and improving energy efficiency. Multiple microwave power sensors 612 allow for individual control of the microwave power of each drying element 52, adjusting it according to its specific needs to avoid unnecessary energy consumption.

[0033] Please refer to Figure 4 The enclosure 21 includes a fixing plate 210 mounted on the housing 10, a connecting rod 211 rotatably mounted on the fixing plate 210, and a rotating locking part 212 threadedly connected to the connecting rod 211. In this embodiment, the rotating locking part 212 is a nut that cooperates with the connecting rod 211. The combination of the fixing plate 210, the connecting rod 211, and the rotating locking part 212 can provide multi-point locking, ensuring a tight connection between the enclosure 21 and the housing 10 and improving sealing. The structure of the rotating locking part 212 ensures that the enclosure 21 will not loosen or open accidentally during operation, enhancing the reliability of the equipment. Through multiple locking mechanisms, microwave leakage can be effectively prevented, ensuring the safety of the operator. The enclosure 21 ensures that heat inside the housing 10 does not dissipate, reducing energy loss and improving energy efficiency. The structure of the rotating locking part 212 allows the operator to quickly lock and unlock the enclosure 21, improving the convenience of operation. With the rotating locking part 212, the operator can complete the locking and unlocking operations with one hand, improving work efficiency.

[0034] The clamping assembly 30 includes a hydraulic cylinder (not shown in the figure) mounted on the housing 10, and a pressure plate (not shown in the figure) mounted on the drive rod of the hydraulic cylinder. The hydraulic cylinder can provide stable and uniform pressure, ensuring that the pressure applied by the pressure plate to the wood is evenly distributed, avoiding excessive or insufficient local pressure; by adjusting the pressure of the hydraulic cylinder, the pressure of the pressure plate can be flexibly adjusted according to the type of wood and drying requirements, improving the clamping effect; the pressure plate can firmly fix the wood, preventing the wood from moving during the drying process and ensuring the stability of the wood during the drying process; by applying pressure evenly, deformation and cracking of the wood during the drying process can be reduced, improving the drying uniformity; the pressure plate can ensure that the wood is firmly fixed in the housing 10, preventing the wood from popping out under high temperature and microwave action, improving operational safety; uniform pressure can reduce irregular movement of the wood during the drying process, avoiding impact and damage to the equipment.

[0035] Please refer to Figure 2 and Figure 3 The microwave drying oven also includes two support frames 80 mounted on the chamber 10 for supporting the wood. These two support frames 80 are placed parallel to each other on the chamber 10. The two parallel support frames 80 ensure that the wood is evenly distributed within the chamber 10, reducing displacement and tilting during the drying process. The parallel support frames 80 provide stable support, preventing the wood from sliding or shifting due to microwave vibration during heating. The two support frames 80 ensure that the wood is evenly placed within the chamber 10, allowing each piece of wood to be heated uniformly, reducing uneven drying caused by temperature gradients. The parallel support frames 80 allow sufficient space to ensure uniform air and microwave circulation within the chamber 10, further improving the drying effect. The two support frames 80 distribute the weight of the wood, preventing individual support frames 80 from deforming or being damaged due to excessive load, thus improving the overall load-bearing capacity. The parallel support frames 80 provide more placement space, allowing for the simultaneous processing of more wood and improving production efficiency.

[0036] The microwave drying oven also includes a drain pipe 90 installed on the cabinet 10 between the support frames 80. The drain pipe 90 is connected to the cabinet 10, and the end face of the drain pipe connected to the cabinet 10 is horizontal with the horizontal plane of the cabinet 10. The structure of the drain pipe 90 can effectively drain the condensate in the cabinet 10, preventing moisture accumulation in the cabinet 10 and affecting the drying effect; timely drainage of condensate can prevent moisture backflow or seepage into the wood, avoiding contamination or re-dampening of the wood; the structure of the drain pipe 90 can ensure that the moisture in the cabinet 10 is drained in time, reducing moisture retention and helping the wood to dry evenly; timely drainage can accelerate the drying process of the wood, shorten the drying time, and improve production efficiency; the structure of the drain pipe 90 can ensure that the moisture is drained in time, reducing the moisture in the cabinet 10, avoiding moisture interference with microwaves, improving the safety and efficiency of microwave use; timely drainage of condensate can prevent the metal parts inside the cabinet 10 from corroding due to prolonged contact with moisture, extending the service life of the equipment.
