Description

Technical Field

[0001] The invention relates to the field of ovens, in particular to a drying oven and a coating device having the drying oven. Background Art

[0002] In the related art, during the production process of the object to be dried (such as the current collector) of the battery cell, after the current collector is coated and printed, the current collector needs to enter the drying oven for heating to remove the moisture from the wet film and make the current collector drier and more stable. The existing drying oven uses a nozzle to blow hot air vertically toward the current collector to dry the current collector, which makes the current collector easy to shake during the drying process, resulting in uneven drying and easy cracking of the current collector, affecting the product quality of the current collector. In addition, during the movement of the current collector, the shaking of the current collector is likely to cause the current collector to break, affecting the production efficiency of the current collector.

[0003] In addition, the hot air used to dry the current collector is discharged through the exhaust port of the drying oven, and the hot air discharge will take away most of the heat, resulting in large heat loss and low energy utilization. The existing drying oven needs to be equipped with a hot air circulation system, which leads to a large volume of the drying oven, a large space occupied by the drying oven, and an increase in the cost of the factory. Summary of the invention

To this end, one object of the present invention is to provide a drying oven, which is conducive to uniform drying of the current collector and reducing the risk of cracking of the current collector, thereby helping to improve the product quality of the current collector and improve the production efficiency of the current collector.

[0012] In some embodiments, the gas flow direction in the first gas flow channel is the same as the gas flow direction in the second gas flow channel; or The gas flow direction in the first gas flow channel is opposite to the gas flow direction in the second gas flow channel.

[0013] In the above technical solution, the gas flow direction in the first gas flow channel is the same as the gas flow direction in the second gas flow channel, or the gas flow direction in the first gas flow channel is opposite to the gas flow direction in the second gas flow channel, so that the object to be dried is suspended in the gas flow channel when the gas flows through the first gas flow channel and the second gas flow channel.

[0015] In the above technical solution, the gas transport device is configured to allow gas to flow into or out of the first gas flow channel, and the gas transport device is also configured to allow gas to flow into or out of the second gas flow channel. The use of one gas transport device can meet the gas flow requirements in the first gas flow channel and the second gas flow channel, which is conducive to simplifying the structure of the drying oven, thereby helping to reduce the complexity of the drying oven structure, and further facilitating the production and manufacturing of the drying oven.

When the drying oven is drying the object to be dried, the opening and closing valve is opened to allow the gas to flow into the first gas flow channel and the second gas flow channel, and the gas in the first gas flow channel and the second gas flow channel can also flow out of the drying oven. When the drying oven is not in use, the opening and closing valve is closed, which can reduce the risk of objects in the external environment entering the drying oven through the air inlet and the exhaust port, thereby helping to keep the drying oven clean, reduce the risk of objects in the external environment affecting the operation of the drying oven, and help the drying oven meet usage requirements.

[0022] In some embodiments, the intake flow passage includes: an intake main flow passage, a first intake branch flow passage and a second intake branch flow passage, the first intake branch flow passage connects the intake main flow passage and the first gas flow passage, and the second intake branch flow passage connects the intake main flow passage and the second gas flow passage.

[0023] In the above technical solution, the main intake channel and the first gas channel are connected by the first intake branch channel, and the main intake channel and the second gas channel are connected by the second intake branch channel, so that the gas can be guided into the first gas channel and the second gas channel. Moreover, by setting up one main intake channel, the gas can be guided into the first intake branch channel and the second intake branch channel, which is conducive to simplifying the structure of the intake channel, thereby helping to simplify the structure of the gas transport device, and further helping to reduce the difficulty of manufacturing the gas transport device.

[0024] In some embodiments, a gas filtering device is provided in the main air inlet passage.

[0025] In the above technical solution, the gas can be filtered by the gas filter device before flowing into the first air inlet branch channel and the second air inlet branch channel, thereby improving the cleanliness of the gas flowing into the first gas flow channel and the second gas flow channel, reducing the risk of contamination of the object to be dried, and making the gas filter device reasonably set.

[0026] In some embodiments, a reserved area for a heating mechanism is provided in the main air intake passage.

[0027] In the above technical solution, by providing a heating mechanism reserved area in the main air intake channel, it is possible to reasonably select whether to install a heating mechanism in the heating mechanism reserved area according to actual usage conditions. When the heating mechanism is installed in the heating mechanism reserved area, the gas flowing through the main air intake channel can be heated by the heating mechanism. When the heated gas flows into the first gas flow channel and the second gas flow channel, the heated gas can dry the object to be dried, thereby further improving the drying efficiency of the object to be dried, which is beneficial to improving the drying capacity of the drying oven.

[0028] In some embodiments, the exhaust flow channel includes: an exhaust main flow channel, a first exhaust branch flow channel and a second exhaust branch flow channel, the first exhaust branch flow channel connects the exhaust main flow channel and the first gas flow channel, and the second exhaust branch flow channel connects the exhaust main flow channel and the second gas flow channel.

[0029] In the above technical solution, the exhaust main channel and the first gas channel are connected by the first exhaust branch channel, and the exhaust main channel and the second gas channel are connected by the second exhaust branch channel, so that the gas in the first gas channel and the second gas channel can be drained out of the drying oven. Moreover, by setting up a main exhaust channel, the gas can be drained out of the drying oven, which is conducive to simplifying the exhaust channel structure, thereby further simplifying the structure of the gas transport device, and further helping to reduce the manufacturing difficulty of the gas transport device.

[0030] In some embodiments, the gas transport device includes: a first box, a second box and a third box, the second box is connected between the first box and the third box, part of the intake channel is formed in the first box and another part is formed in the second box, part of the exhaust channel is formed in the third box and another part is formed in the second box, and the first fan and the second fan are both arranged in the second box.

[0031] In the above technical solution, by arranging the first box body, the second box body and the third box body, the gas can flow into the first gas flow channel and the second gas flow channel from the same side of the drying oven, and the gas in the first gas flow channel and the second gas flow channel can also flow out from the same side of the drying oven, so that the structure of the gas transport device is simple, which is conducive to simplifying the structure of the drying oven, and can make the structure of the drying oven more compact, which is conducive to reducing the volume of the drying oven.

[0032] In some embodiments, the drying oven further includes: a negative pressure exhaust pipe, wherein a feed port and a discharge port are respectively formed at opposite ends of the object channel along the first direction, and the negative pressure exhaust pipe is connected to at least one of the feed port and the discharge port.

[0033] In the above technical solution, a negative pressure exhaust pipe is provided, and the negative pressure exhaust pipe is connected to at least one of the feed port and the discharge port.

The gas in the gas flow channel can be extracted through the negative pressure exhaust pipe, thereby reducing the risk of gas in the gas flow channel overflowing from the feed port and the discharge port. Since the gas in the gas flow channel has a certain temperature, the risk of gas in the gas flow channel overflowing from the feed port and the discharge port and scalding the user can be reduced, which is beneficial to improving the safety of using the drying oven.

[0034] In some embodiments, the heating device is a light heating device or an electromagnetic heating device.

[0035] In the above technical scheme, the heating device is configured as a light heating device or an electromagnetic heating device. Compared with a case where the heating device is configured as a drying oven and uses a nozzle to dry the object to be dried, the drying oven of the present invention does not need to be provided with a hot air circulation system, which is beneficial to reducing the volume of the drying oven, reducing the space occupied by the drying oven, and reducing the cost of the factory building. It is also beneficial to improve the heating efficiency of the heating device, improve the heating speed of the heating device, and at the same time, the heating device can use more energy for drying, which is beneficial to improve energy utilization. In addition, it is beneficial to reduce the temperature inside the oven body, making the production process safer.

[0037] In the above technical solution, a heating device is provided on at least one side of the gas flow channel, and the heating device can be reasonably selected on one side or both sides of the gas flow channel according to actual needs. When heating devices are provided on both sides of the gas flow channel, during the process of drying the object to be dried, the heating devices located on both sides of the object to be dried can dry the two surfaces of the object to be dried respectively, and the two surfaces of the object to be dried can be heated and dried at the same time, which is conducive to further improving the drying efficiency of the object to be dried.

[0038] In some embodiments, a partition is provided in the oven body, the partition is located between the heating device and the gas flow channel, and the partition is configured as a flow channel wall of the gas flow channel.

A transparent portion is formed by the partition, and when the heating device is set as a light heating device, when the heating device emits heating light toward the object to be dried, the light can pass through the corresponding transparent portion and act on the object to be dried, achieving the effect of heating and drying the object to be dried. In addition, when the heating device is set as an electromagnetic heating device, the effect of heating and drying the object to be dried can also be achieved.

[0040] In some embodiments, there are multiple heating devices, and along the second direction, the multiple heating devices are respectively located on both sides of the gas flow channel, and the heating device located on one side of the gas flow channel and the heating device located on the other side of the gas flow channel are at least partially staggered along the first direction.

[0042] In some embodiments, the position of the heating device is adjustable along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0053] In the embodiments of the present invention, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present invention shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary and should not constitute any limitation to the present invention.

[0054] The term “plurality” used in the present invention refers to two or more (including two).

[0055] In the battery cell coating production process, during the production process of the object to be dried of the battery cell, as an example, the object to be dried is a current collector, which needs to be dried.

[0056] In the present invention, the battery cell may include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery or a magnesium-ion battery, etc., and the embodiments of the present invention do not limit this.

[0057] The battery cell includes a shell, an electrode assembly and an electrolyte, and the shell is used to contain the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet and a separator. The battery cell mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer.

[0059] In recent years, new energy vehicles have developed by leaps and bounds. In the field of electric vehicles, battery cells, as the power source of electric vehicles, play an irreplaceable and important role. As the core components of new energy vehicles, battery cells have high requirements in terms of reliability.

[0060] During the production process of the objects to be dried (such as current collectors) of battery cells, after the current collectors are coated and printed, they need to enter the drying oven for heating to remove moisture from the wet film and make the current collectors drier and more stable. Existing drying ovens use a nozzle to blow hot air vertically toward the current collectors to dry them, which makes the current collectors easy to shake during the drying process, resulting in uneven drying and easy cracking of the current collectors, affecting the product quality of the current collectors. In addition, during the movement of the current collectors, the shaking of the current collectors can easily cause the current collectors to break, affecting the production efficiency of the current collectors.

[0061] Based on the above considerations, in order to solve the problem that the current collector is easy to shake during the drying process, after in-depth research, a drying oven is designed, including: an oven body, a gas flow channel is formed in the oven body, the gas flow channel is suitable for the object to be dried to pass through along the first direction, and the gas flow channel is configured to make the object to be dried suspended in the gas flow channel when the gas flows through the gas flow channel; a heating device, the heating device is arranged on the oven body, and the heating device is used to heat the object to be dried. The gas flow channel is configured to make the object to be dried suspended in the gas flow channel when the gas flows through the gas flow channel, so that the position of the object to be dried can be stabilized and the shaking of the object to be dried can be reduced. Compared with the prior art, the risk of shaking of the object to be dried can be reduced during the drying process of the object to be dried, which is conducive to uniform drying of the object to be dried and reducing the risk of cracking of the object to be dried, thereby helping to improve the product quality of the object to be dried, and reducing the risk of belt breakage of the object to be dried, thereby helping to improve the production efficiency of the object to be dried.

[0062] Reference below Figure 1-Figure 7 The drying oven 100 according to the embodiment of the present invention is described. The drying oven 100 is used to dry an object 200 to be dried. The object 200 to be dried may be a current collector.

[0063] like Figure 1-Figure 7 As shown, the drying oven 100 according to the embodiment of the present invention comprises: an oven body 10, a gas flow channel 11 is formed in the oven body 10, the gas flow channel 11 is suitable for the object 200 to be dried to pass through along the first direction, the gas in the gas flow channel 11 is suitable for flowing along the first direction, and the gas flow channel 11 is configured to make the object 200 to be dried suspend in the gas flow channel 11 when the gas flows through the gas flow channel 11. A heating device 20, the heating device 20 is arranged in the oven body 10, and the heating device 20 is used to heat the object 200 to be dried.

[0064] The oven body 10 may be constructed as a metal box, or as a glass box, so that the interior of the oven body 10 can be viewed. A gas flow channel 11 is formed in the oven body 10, and gas can be blown into the gas flow channel 11. The gas in the gas flow channel 11 can flow out of the gas flow channel 11. When the gas is blown into the gas flow channel 11, it can flow along the gas flow channel 11, so that the gas flows out of the gas flow channel 11 along the gas flow channel 11. When the gas flows out of the gas flow channel 11, it can take away the water vapor generated by drying the object 200 to be dried in the drying oven 100. The gas flow channel 11 can extend along a first direction, and the object 200 to be dried passes through the gas flow channel 11 along the first direction, and the object 200 to be dried passes through the oven body 10. The present invention is based on the drying oven 100 with Figure 5 Direction placement is used as an example to illustrate the first direction. Figure 5Along the first direction, the gas can flow into the gas flow channel 11 from one end of the gas flow channel 11, and the gas in the gas flow channel 11 can flow out of the gas flow channel 11 from the other end.

[0065] The heating device 20 is arranged on the oven body 10. The heating device 20 can be configured as a light heating device 20 or an electromagnetic heating device 20. The light heating device 20 can be an infrared lamp, an infrared plate, a UV ultraviolet lamp, etc. The electromagnetic heating device 20 can be an electromagnetic heating plate, etc. The heating device 20 can be arranged inside the oven body 10. Compared with the case where the heating device 20 is configured as a drying oven 100 using a nozzle to dry the object 200 to be dried, the drying oven 100 of the present invention does not need to be provided with a hot air circulation system, which is conducive to reducing the volume of the drying oven 100, reducing the space occupied by the drying oven 100, and reducing the factory building cost.

[0066] When the object to be dried 200 passes through the gas flow channel 11 along the first direction, the object to be dried 200 passes through the gas flow channel 11 along the second direction. Figure 5 In the Z direction, both sides of the object 200 to be dried have gas flow channels 11, and the gas flowing into the gas flow channels 11 is room temperature gas, which is more energy-efficient than hot air. When the gas flows in the gas flow channels 11 on both sides of the object 200 to be dried along the first direction, the object 200 to be dried can be suspended in the gas flow channels 11, so that the position of the object 200 to be dried is stable, and the shaking amount of the object 200 to be dried is reduced. Compared with the prior art, during the drying process of the object 200 to be dried, the shaking risk of the object 200 to be dried can be reduced, which is conducive to uniform drying of the object 200 to be dried, and the risk of cracking of the object 200 to be dried is reduced, thereby facilitating the improvement of the product quality of the object 200 to be dried. In addition, when the object 200 to be dried moves along the first direction, the risk of belt breakage of the object 200 to be dried can be reduced, thereby facilitating the improvement of the production efficiency of the object 200 to be dried.

[0067] In the above technical solution, the gas flow channel 11 is configured to suspend the object 200 to be dried in the gas flow channel 11 when the gas flows through the gas flow channel 11, so that the position of the object 200 to be dried can be stabilized and the shaking of the object 200 to be dried can be reduced. Compared with the prior art, during the drying process of the object 200 to be dried, the risk of shaking of the object 200 to be dried can be reduced, which is conducive to uniform drying of the object 200 to be dried and reducing the risk of cracking of the object 200 to be dried, thereby facilitating improving the product quality of the object 200 to be dried, and reducing the risk of belt breakage of the object 200 to be dried, thereby facilitating improving the production efficiency of the object 200 to be dried.

[0068] According to some embodiments of the present invention, Figure 5As shown, the gas flow channel 11 includes: an object channel 111, a first gas flow channel 112 and a second gas flow channel 113. Along the second direction, the object channel 111 is located between the first gas flow channel 112 and the second gas flow channel 113. The object channel 111 connects the first gas flow channel 112 and the second gas flow channel 113. The object channel 111 is suitable for the object 200 to be dried to pass through. The first direction and the second direction are perpendicular.

[0069] The gas flow channel 11 includes an object channel 111, a first gas flow channel 112, and a second gas flow channel 113. The object channel 111, the first gas flow channel 112, and the second gas flow channel 113 are arranged along the second direction, and the object channel 111 is located between the first gas flow channel 112 and the second gas flow channel 113. Figure 5 As shown, along the second direction, the first gas flow channel 112 is located above the second gas flow channel 113, the object channel 111 is open toward the end of the first gas flow channel 112, and the object channel 111 is open toward the end of the second gas flow channel 113, so that the object channel 111 connects the first gas flow channel 112 and the second gas flow channel 113. The object 200 to be dried passes through the object channel 111, so that both sides of the object 200 to be dried have the gas flow channel 11, and then when the gas flows through the first gas flow channel 112 and the second gas flow channel 113, the object 200 to be dried is suspended in the gas flow channel 11.

[0070] In the above technical solution, along the second direction, the object channel 111 is located between the first gas flow channel 112 and the second gas flow channel 113, and the object channel 111 is connected to the first gas flow channel 112 and the second gas flow channel 113. When the object 200 to be dried passes through the object channel 111, the effect of having the gas flow channel 11 on both sides of the object 200 to be dried is achieved, and then when the gas flows through the first gas flow channel 112 and the second gas flow channel 113, the object 200 to be dried is suspended in the gas flow channel 11.

[0071] According to some embodiments of the present invention, Figure 5 As shown, the object channel 111, the first gas flow channel 112 and the second gas flow channel 113 are parallel to each other.

[0072] Among them, along the first direction, the object channel 111, the first gas flow channel 112 and the second gas flow channel 113 are arranged in parallel with each other, or the object channel 111, the first gas flow channel 112 and the second gas flow channel 113 are arranged approximately in parallel with each other. After the object 200 to be dried passes through the object channel 111, when the gas flows through the first gas flow channel 112 and the second gas flow channel 113, it is beneficial to stabilize the suspension of the object 200 to be dried, thereby further reducing the shaking amount of the object 200 to be dried.

[0073] In the above technical solution, the object channel 111, the first gas flow channel 112 and the second gas flow channel 113 are arranged in parallel with each other. When the gas flows through the first gas flow channel 112 and the second gas flow channel 113, it is beneficial to stabilize the suspension of the object 200 to be dried, thereby further reducing the shaking amount of the object 200 to be dried.

[0074] According to some embodiments of the present invention, Figure 5 As shown, the gas flow direction in the first gas flow channel 112 is the same as the gas flow direction in the second gas flow channel 113. Alternatively, the gas flow direction in the first gas flow channel 112 is opposite to the gas flow direction in the second gas flow channel 113.

[0075] Among them, Figure 5 As shown, the gas flow direction in the first gas flow channel 112 is the same as the gas flow direction in the second gas flow channel 113. As an example, the gas flows into the first gas flow channel 112 through the right end of the first gas flow channel 112 and flows out of the first gas flow channel 112 from the left end of the first gas flow channel 112, and the gas flows into the second gas flow channel 113 through the right end of the second gas flow channel 113 and flows out of the second gas flow channel 113 from the left end of the second gas flow channel 113.

[0076] Alternatively, the gas flow direction in the first gas flow channel 112 is opposite to the gas flow direction in the second gas flow channel 113. Figure 5 As shown, as an example, the gas flows into the first gas flow channel 112 through the right end of the first gas flow channel 112 and flows out of the first gas flow channel 112 from the left end of the first gas flow channel 112, and the gas flows into the second gas flow channel 113 through the left end of the second gas flow channel 113 and flows out of the second gas flow channel 113 from the right end of the second gas flow channel 113. As another example, the gas flows into the first gas flow channel 112 through the left end of the first gas flow channel 112 and flows out of the first gas flow channel 112 from the right end of the first gas flow channel 112, and the gas flows into the second gas flow channel 113 through the right end of the second gas flow channel 113 and flows out of the second gas flow channel 113 from the left end of the second gas flow channel 113.

[0077] In the above technical solution, the gas flow direction in the first gas flow channel 112 is the same as the gas flow direction in the second gas flow channel 113, or the gas flow direction in the first gas flow channel 112 is opposite to the gas flow direction in the second gas flow channel 113, so that the object to be dried 200 is suspended in the gas flow channel 11 when the gas flows through the first gas flow channel 112 and the second gas flow channel 113.

[0078] According to some embodiments of the present invention, Figure 1 , Figure 2 and Figure 5 As shown, the drying oven 100 also includes: a gas transport device 30, which is connected to the first gas flow channel 112 and the second gas flow channel 113, and the gas transport device 30 is configured to allow gas to flow into or out of the first gas flow channel 112, and the gas transport device 30 is also configured to allow gas to flow into or out of the second gas flow channel 113.

[0079] The drying oven 100 may further include: a gas transport device 30, wherein the first gas channel 112 has a first gas channel inlet 1121 and a first gas channel outlet 1122, and the gas transport device 30 is connected to both the first gas channel inlet 1121 and the first gas channel outlet 1122. When the gas transport device 30 is in operation, the gas flows into the first gas channel 112 through the first gas channel inlet 1121, and the gas in the first gas channel 112 flows out of the first gas channel 112 through the first gas channel outlet 1122. The second gas channel 113 has a second gas channel inlet 1131 and a second gas channel outlet 1132, and the gas transport device 30 is connected to both the second gas channel inlet 1131 and the second gas channel outlet 1132. When the gas transport device 30 is in operation, the gas flows into the second gas channel 113 through the second gas channel inlet 1131, and the gas in the second gas channel 113 flows out of the first gas channel 112 through the second gas channel outlet 1132. Figure 5 As shown, along the first direction, the present invention is explained by taking the right end of the first gas channel 112 as the first gas channel inlet 1121 and the left end of the first gas channel 112 as the first gas channel outlet 1122 as an example, and is explained by taking the right end of the second gas channel 113 as the second gas channel inlet 1131 and the left end of the second gas channel 113 as the second gas channel outlet 1132 as an example.

[0080] As an example, the gas transport device 30 is constructed as a hair dryer, which is connected to both the first gas flow channel inlet 1121 and the second gas flow channel inlet 1131. The hair dryer blows air into the first gas flow channel 112 and the second gas flow channel 113 to make the gas in the first gas flow channel 112 flow along the first direction, and the gas in the second gas flow channel 113 flow along the first direction, so that the gas in the first gas flow channel 112 flows out of the first gas flow channel 112 from the first gas flow channel outlet 1122, and the gas in the second gas flow channel 113 flows out of the second gas flow channel 113 from the second gas flow channel outlet 1132.

[0081] As another example, the gas transport device 30 is constructed as an exhaust fan, which is connected to the first gas flow channel outlet 1122 and the second gas flow channel outlet 1132. Through the operation of the exhaust fan, gas is drawn into the first gas flow channel 112 from the first gas flow channel inlet 1121, so that the gas in the first gas flow channel 112 flows along the first direction, and gas is drawn into the second gas flow channel 113 from the second gas flow channel inlet 1131, so that the gas in the second gas flow channel 113 flows along the first direction, so that the gas in the first gas flow channel 112 flows out of the first gas flow channel 112 from the first gas flow channel outlet 1122, and the gas in the second gas flow channel 113 flows out of the second gas flow channel 113 from the second gas flow channel outlet 1132.

[0082] In the above technical solution, the gas transport device 30 is configured to allow gas to flow into or out of the first gas flow channel 112, and the gas transport device 30 is also configured to allow gas to flow into or out of the second gas flow channel 113. The use of one gas transport device 30 can meet the gas flow requirements in the first gas flow channel 112 and the second gas flow channel 113, which is beneficial to simplify the structure of the drying oven 100, thereby helping to reduce the structural complexity of the drying oven 100, and further facilitating the production of the drying oven 100.

[0083] According to some embodiments of the present invention, Figure 1 , Figure 2 and Figure 7 As shown, the gas transport device 30 has an inlet flow channel 31, an exhaust flow channel 32, a first fan 33 and a second fan 34. The inlet flow channel 31 is connected to the first gas flow channel 112 and the second gas flow channel 113. The first fan 33 is configured to allow the gas to flow into the first gas flow channel 112 and the second gas flow channel 113 through the inlet flow channel 31. The exhaust flow channel 32 is connected to the first gas flow channel 112 and the second gas flow channel 113. The second fan 34 is configured to allow the gas to flow out of the first gas flow channel 112 and the second gas flow channel 113.

[0084] The gas transport device 30 includes an inlet flow channel 31, an exhaust flow channel 32, a first fan 33, and a second fan 34. The inlet flow channel 31 is connected to the first gas flow channel 112 and the second gas flow channel 113. As an example, the inlet flow channel 31 is directly connected to the first gas flow channel 112 and the second gas flow channel 113, so that the inlet flow channel 31 is connected to the first gas flow channel 112 and the second gas flow channel 113. As another example, the inlet flow channel 31 is indirectly connected to the first gas flow channel 112 and the second gas flow channel 113 through a connecting pipe. The exhaust flow channel 32 is connected to the first gas flow channel 112 and the second gas flow channel 113. As an example, the exhaust flow channel 32 is directly connected to the first gas flow channel 112 and the second gas flow channel 113, so that the exhaust flow channel 32 is connected to the first gas flow channel 112 and the second gas flow channel 113. As another example, the exhaust flow channel 32 is indirectly connected to the first gas flow channel 112 and the second gas flow channel 113 through a connecting pipe.

[0085] The first fan 33 can be a circulating fan. The first fan 33 can be arranged in the inlet flow channel 31. When the first fan 33 is working, the first fan 33 can make the gas outside the drying oven 100 flow into the inlet flow channel 31. The gas flowing into the inlet flow channel 31 flows into the first gas flow channel 112 and the second gas flow channel 113 under the action of the first fan 33, so that the gas flows along the first direction in the first gas flow channel 112 and the second gas flow channel 113.

[0086] The second fan 34 can be an exhaust fan, and the second fan 34 can be set at the exhaust port 36 of the exhaust channel 32. When the second fan 34 is working, the gas in the first gas channel 112 and the gas in the second gas channel 113 can flow into the exhaust channel 32, and the gas flowing into the exhaust channel 32 can flow out of the drying oven 100 through the exhaust port 36 of the exhaust channel 32.

[0087] In the above technical solution, by providing the inlet flow channel 31, the exhaust flow channel 32, the first fan 33 and the second fan 34, the effect of gas flowing into the first gas flow channel 112 and the second gas flow channel 113 can be achieved, and the effect of gas flowing out of the first gas flow channel 112 and the second gas flow channel 113 can also be achieved, which is conducive to achieving the effect of suspending the object 200 to be dried in the gas flow channel 11.

[0088] According to some embodiments of the present invention, Figure 1 , Figure 2 and Figure 7 As shown, the inlet channel 31 has an air inlet 35 , which connects the inlet channel 31 with the external environment of the drying oven 100 , and the exhaust channel 32 has an exhaust port 36 , which connects the exhaust channel 32 with the external environment of the drying oven 100 .

[0089] The inlet flow channel 31 is connected to the air inlet 35, and the air inlet 35 is connected to the external environment of the drying oven 100. When the first fan 33 is working, the gas can flow into the inlet flow channel 31 through the air inlet 35 to meet the demand for air supply to the inlet flow channel 31, thereby meeting the demand for air supply to the first gas flow channel 112 and the second gas flow channel 113. The exhaust flow channel 32 is connected to the exhaust port 36, and the exhaust port 36 is connected to the exhaust flow channel 32 and the external environment of the drying oven 100. When the second fan 34 is working, the gas in the first gas flow channel 112 and the second gas flow channel 113 can be discharged from the drying oven 100 through the exhaust flow channel 32 and the exhaust port 36, thereby meeting the demand for exhaust in the first gas flow channel 112 and the second gas flow channel 113. Furthermore, when the gas in the first gas flow channel 112 and the second gas flow channel 113 flows out from the exhaust port 36 , it can take away the water vapor generated by drying the object 200 to be dried in the drying oven 100 , thereby facilitating the improvement of the drying efficiency of the object 200 to be dried.

[0090] In the above technical solution, the inlet duct 31 and the external environment of the drying oven 100 are connected through the air inlet 35. When the first fan 33 is working, the gas can flow into the inlet duct 31 through the air inlet 35 to meet the demand of supplying air to the inlet duct 31, thereby meeting the demand of supplying air to the first gas flow channel 112 and the second gas flow channel 113. The exhaust duct 32 and the external environment of the drying oven 100 are connected through the exhaust duct 36. When the second fan 34 is working, the gas in the first gas flow channel 112 and the second gas flow channel 113 can be discharged from the drying oven 100 through the exhaust duct 32 and the exhaust duct 36, thereby meeting the demand of exhausting air in the first gas flow channel 112 and the second gas flow channel 113. Moreover, when the gas in the first gas flow channel 112 and the second gas flow channel 113 flows out from the exhaust duct 36, it can take away the water vapor generated by drying the object 200 to be dried in the drying oven 100, thereby facilitating the drying efficiency of the object 200 to be dried.

[0091] According to some embodiments of the present invention, at least one of the air inlet 35 and the air outlet 36 is provided with an opening and closing valve.

[0092] As an example, the air inlet 35 is provided with an opening and closing valve. As another example, the exhaust port 36 is provided with an opening and closing valve. As another example, both the air inlet 35 and the exhaust port 36 are provided with opening and closing valves. The present invention is described by taking the air inlet 35 and the exhaust port 36 as an example in which both the air inlet 35 and the exhaust port 36 are provided with opening and closing valves. The opening and closing valve may be a mechanical valve, which can be opened or closed manually by a user. The opening and closing valve may also be an electric valve, which can be opened or closed electrically. When the drying oven 100 dries the object 200 to be dried, the opening and closing valve at the air inlet 35 and the opening and closing valve at the exhaust port 36 are both opened, so that the gas can flow into the first gas flow channel 112 and the second gas flow channel 113, and the gas in the first gas flow channel 112 and the second gas flow channel 113 can also flow out of the drying oven 100. When the drying oven 100 is not in use, the on-off valve at the air inlet 35 and the on-off valve at the exhaust port 36 are closed, which can reduce the risk of objects in the external environment (dust, animals, etc.) entering the drying oven 100 through the air inlet 35 and the exhaust port 36, thereby helping to keep the drying oven 100 clean, reducing the risk of objects in the external environment affecting the operation of the drying oven 100, and helping to ensure that the drying oven 100 meets usage requirements.

[0093] In the above technical solution, at least one of the air inlet 35 and the exhaust port 36 is provided with an opening and closing valve, and the opening and closing valve can be selectively opened or closed. When the drying oven 100 dries the object 200 to be dried, the opening and closing valve is opened to allow the gas to flow into the first gas flow channel 112 and the second gas flow channel 113, and the gas in the first gas flow channel 112 and the second gas flow channel 113 can also flow out of the drying oven 100. When the drying oven 100 is not in use, the opening and closing valve is closed, which can reduce the risk of objects in the external environment entering the drying oven 100 through the air inlet 35 and the exhaust port 36, thereby helping to keep the drying oven 100 clean, reduce the risk of objects in the external environment affecting the operation of the drying oven 100, and help the drying oven 100 meet the usage requirements.

[0094] According to some embodiments of the present invention, Figure 2 , Figure 5 and Figure 7 As shown, the intake flow channel 31 includes: an intake main flow channel 311, a first intake branch flow channel 312 and a second intake branch flow channel 313. The first intake branch flow channel 312 connects the intake main flow channel 311 and the first gas flow channel 112, and the second intake branch flow channel 313 connects the intake main flow channel 311 and the second gas flow channel 113.

[0095] Among them, the intake flow channel 31 may include an intake main channel 311, a first intake branch channel 312 and a second intake branch channel 313. One end of the intake main channel 311 is connected to the intake port 35, and the other end of the intake main channel 311 is connected to the first intake branch channel 312. The first intake branch channel 312 is connected to the first gas channel 112, so that the first intake branch channel 312 connects the intake main channel 311 and the first gas channel 112, so that the gas flowing in from the intake port 35 can flow into the first gas channel 112 through the intake main channel 311 and the first intake branch channel 312. The other end of the main intake channel 311 is also connected to the second intake branch channel 313, and the second intake branch channel 313 is connected to the second gas channel 113, so that the second intake branch channel 313 connects the main intake channel 311 and the second gas channel 113, so that the gas flowing in from the air inlet 35 can flow into the second gas channel 113 through the main intake channel 311 and the second intake branch channel 313.

[0096] In the above technical scheme, the main intake channel 311 and the first gas channel 112 are connected by the first intake branch channel 312, and the second intake branch channel 313 is connected by the main intake channel 311 and the second gas channel 113, so that the gas can be guided into the first gas channel 112 and the second gas channel 113. Moreover, by setting a main intake channel 311, the gas can be guided into the first intake branch channel 312 and the second intake branch channel 313, which is conducive to simplifying the structure of the intake channel 31, thereby helping to simplify the structure of the gas transport device 30, and further helping to reduce the manufacturing difficulty of the gas transport device 30.

[0097] According to some embodiments of the present invention, Figure 2 and Figure 7 As shown, a gas filtering device 40 is provided in the main air intake passage 311 .

[0098] The drying oven 100 includes a gas filter device 40, which can be a medium-efficiency circulation filter. When the gas flows through the gas filter device 40, the gas filter device 40 can filter out particulate matter in the gas, such as dust, fiber and some bacteria, to improve the cleanliness of the gas. The gas filter device 40 can be arranged in the main inlet channel 311. When the gas flows into the inlet channel 31 through the air inlet 35, the gas flows from the main inlet channel 311 into the first inlet branch channel 312 and the second inlet branch channel 313. Therefore, by arranging the gas filter device 40 in the main inlet channel 311, the gas can be filtered by the gas filter device 40 before flowing into the first inlet branch channel 312 and the second inlet branch channel 313, thereby improving the cleanliness of the gas flowing into the first gas channel 112 and the second gas channel 113, reducing the risk of contamination of the object 200 to be dried, and thus making the gas filter device 40 reasonably arranged.

[0099] In the above technical solution, by providing a gas filter device 40 in the main air inlet channel 311, the gas can be filtered by the gas filter device 40 before flowing into the first air inlet branch channel 312 and the second air inlet branch channel 313, thereby improving the cleanliness of the gas flowing into the first gas flow channel 112 and the second gas flow channel 113, reducing the risk of contamination of the object to be dried 200, and making the gas filter device 40 reasonably disposed.

[0100] According to some embodiments of the present invention, Figure 2 and Figure 7 As shown, a heating mechanism reserved area 50 is provided in the main intake passage 311 .

The heating mechanism reserved area 50 can be installed with a heating mechanism, and the heating mechanism can be a heating rod, a heating tube, etc. The user can reasonably choose whether to install a heating mechanism in the heating mechanism reserved area 50 according to actual use. When the heating mechanism reserved area 50 is installed with a heating mechanism, the gas flowing through the main inlet channel 311 can be heated by the heating mechanism. When the heated gas flows into the first gas flow channel 112 and the second gas flow channel 113, the heated gas can dry the object to be dried 200, thereby further improving the drying efficiency of the object to be dried 200, which is beneficial to improve the drying capacity of the drying oven 100.

[0102] In the above technical solution, by providing a heating mechanism reserved area 50 in the air inlet main channel 311, it is possible to reasonably select whether to install a heating mechanism in the heating mechanism reserved area 50 according to actual usage conditions. When the heating mechanism reserved area 50 is installed with a heating mechanism, the gas flowing through the air inlet main channel 311 can be heated by the heating mechanism. When the heated gas flows into the first gas flow channel 112 and the second gas flow channel 113, the heated gas can dry the object to be dried 200, thereby further improving the drying efficiency of the object to be dried 200, which is beneficial to improving the drying capacity of the drying oven 100.

[0104] The exhaust flow channel 32 may include an exhaust main flow channel 321, a first exhaust branch flow channel 322, and a second exhaust branch flow channel 323. One end of the exhaust main flow channel 321 is connected to the exhaust port 36, and the other end of the exhaust main flow channel 321 is connected to the first exhaust branch flow channel 322. The first exhaust branch flow channel 322 is connected to the first gas flow channel 112, so that the first exhaust branch flow channel 322 is connected to the exhaust main flow channel 321 and the first gas flow channel 112, so that the gas in the first gas flow channel 112 flows out of the drying oven 100 through the first exhaust branch flow channel 322, the exhaust main flow channel 321, and the exhaust port 36. The other end of the exhaust main flow channel 321 is also connected to the second exhaust branch flow channel 323, and the second exhaust branch flow channel 323 is connected to the second gas flow channel 113, so that the gas in the second gas flow channel 113 flows out of the drying oven 100 through the second exhaust branch flow channel 323, the exhaust main flow channel 321, and the exhaust port 36.

[0117] Among them, the drying oven 100 can also include: a negative pressure exhaust pipe 60, along the first direction, the opposite ends of the object channel 111 are respectively formed with a feed port 1111 and an outlet port 1112, the object channel 111 is connected to the feed port 1111 and the outlet port 1112, the negative pressure exhaust pipe 60 is connected to at least one of the feed port 1111 and the outlet port 1112, that is, the negative pressure exhaust pipe 60 is connected to the feed port 1111, or the negative pressure exhaust pipe 60 is connected to the outlet port 1112, or the negative pressure exhaust pipe 60 is connected to both the feed port 1111 and the outlet port 1112.

The exhaust device may be a second fan 34, or a separately arranged exhaust fan.

[0118] In the above technical solution, a negative pressure exhaust pipe 60 is provided, and the negative pressure exhaust pipe 60 is connected to at least one of the feed port 1111 and the discharge port 1112. When the exhaust device is working, the gas at the feed port 1111 is extracted through the first exhaust pipe 61 to form a negative pressure in the feed port 1111, and the gas at the discharge port 1112 is extracted through the second exhaust pipe 62 to form a negative pressure in the discharge port 1112. The gas in the gas flow channel 11 can be extracted through the negative pressure exhaust pipe 60, thereby reducing the risk of gas in the gas flow channel 11 overflowing from the feed port 1111 and the discharge port 1112. Since the gas in the gas flow channel 11 has a certain temperature, the risk of gas in the gas flow channel 11 overflowing from the feed port 1111 and the discharge port 1112 to scald the user can be reduced, which is beneficial to improving the safety of the drying oven 100.

[0119] According to some embodiments of the present invention, Figure 5As shown, the heating device 20 is disposed in the oven body 10 , and the heating device 20 is disposed on at least one side of the gas flow channel 11 along a second direction perpendicular to the first direction.

[0120] The heating device 20 is disposed in the oven body 10. The heating device 20 can be disposed in the oven body 10 along a second direction, which is perpendicular to the first direction. Figure 5 In the Z direction, a heating device 20 is provided on one side of the gas flow channel 11, or heating devices 20 are provided on both sides of the gas flow channel 11. The present invention is described by taking the case where heating devices 20 are provided on both sides of the gas flow channel 11 along the second direction as an example. After the object 200 to be dried passes through the gas flow channel 11, heating devices 20 are provided on both sides of the object 200 to be dried along the second direction.

[0121] In the above technical solution, the heating device 20 is provided on at least one side of the gas flow channel 11. The heating device 20 can be reasonably selected on one side or both sides of the gas flow channel 11 according to actual needs. When the heating devices 20 are provided on both sides of the gas flow channel 11, during the drying process of the object 200 to be dried, the heating devices 20 located on both sides of the object 200 to be dried can dry the two surfaces of the object 200 to be dried respectively. The two surfaces of the object 200 to be dried are heated and dried at the same time, which is conducive to further improving the drying efficiency of the object 200 to be dried.

[0122] According to some embodiments of the present invention, the heating device 20 is a light heating device 20 or an electromagnetic heating device 20 .

[0123] The heating device 20 may be configured as a light heating device 20 , or the heating device 20 may be configured as an electromagnetic heating device 20 .

[0124] As an example, when the heating device 20 is set as a light heating device 20, the light heating device 20 can be an infrared lamp, an infrared plate, a UV ultraviolet lamp, a laser heater, etc. The present invention is described by taking the light heating device 20 as a laser heater as an example. When the laser heater is used to dry the object 200 to be dried, the laser heater emits a continuous laser beam toward the object 200 to be dried, the laser spot can be adjusted in size, and the heating range of the laser heater is variable, so that the laser heater is compatible with various specifications of objects 200 to be dried. The laser beam penetrates deeply and directly acts on the slurry on the surface of the object 200 to be dried. The electrons in the slurry on the surface of the object 200 to be dried absorb the energy of the laser and release heat by transition, so that the object 200 to be dried quickly heats up, and the released heat is transferred to the water, and the water absorbs heat and evaporates, thereby achieving the effect of drying the object 200 to be dried. Moreover, when drying the object 200 to be dried using the light heating device 20, compared with drying the object 200 to be dried by blowing hot air, the external environment of the drying oven 100 absorbs less energy, the object 200 to be dried absorbs more heat, and the overall energy utilization rate is higher than that of hot air heating.

[0125] It should be noted that the laser heater can be a continuous laser heater, which has a stable working state, i.e. steady state. The number of particles at each energy level in the continuous laser heater and the radiation field in the cavity have a stable distribution. The working characteristics of the continuous laser heater are that the excitation of the working material and the corresponding laser output can be carried out continuously over a long period of time, which is very suitable for drying processes that require long-term continuous operation.

[0126] As another example, when the heating device 20 is set as an electromagnetic heating device 20, the electromagnetic heating device 20 converts electrical energy into thermal energy. The electromagnetic heating device 20 uses electromagnetic induction to generate eddy currents in the object to be dried 200 to electrically heat the object to be dried 200. It converts electrical energy into electromagnetic energy, and then converts electromagnetic energy into electrical energy. The electrical energy is converted into thermal energy inside the object to be dried 200, thereby achieving the purpose of heating the object to be dried 200.

[0127] In the above technical scheme, the heating device 20 is set as a light heating device 20 or an electromagnetic heating device 20. Compared with the case where the heating device 20 is constructed as a drying oven 100 and uses a nozzle to dry the object 200 to be dried, the drying oven 100 of the present invention does not need to be provided with a hot air circulation system, which is beneficial to reducing the volume of the drying oven 100, reducing the space occupied by the drying oven 100, and reducing the factory cost. It is also beneficial to improve the heating efficiency of the heating device 20, which is beneficial to improve the heating speed of the heating device 20. At the same time, the heating device 20 can use more energy for drying, which is beneficial to improve energy utilization. In addition, it is beneficial to reduce the temperature inside the oven body 10, making the production process safer.

[0128] According to some embodiments of the present invention, Figure 5 As shown, there are multiple heating devices 20, and along the second direction, the multiple heating devices 20 are respectively located on both sides of the gas flow channel 11, and the heating device 20 located on one side of the gas flow channel 11 and the heating device 20 located on the other side of the gas flow channel 11 are at least partially staggered along the first direction.

[0129] Wherein, the heating device 20 is provided in plurality, and along the second direction, a portion of the heating device 20 is located on one side of the gas flow channel 11, and another portion of the heating device 20 is located on the other side of the gas flow channel 11. Multiple heating devices 20 may be provided on both sides of the gas flow channel 11. The present invention is described by taking two heating devices 20 provided on both sides of the gas flow channel 11 as an example. Figure 5 As shown, the heating device 20 located at the lower side of the gas flow channel 11 and the heating device 20 located at the upper side of the gas flow channel 11 are at least partially staggered along the first direction, that is, the heating device 20 located at the lower side of the gas flow channel 11 and the heating device 20 located at the upper side of the gas flow channel 11 can be partially staggered along the first direction, or as shown in FIG. Figure 5 As shown, the heating device 20 located at the lower side of the gas flow channel 11 and the heating device 20 located at the upper side of the gas flow channel 11 can be staggered along the first direction. The orthographic projection of the heating device 20 located at the lower side of the gas flow channel 11 and staggered with the heating device 20 located at the upper side of the gas flow channel 11 along the second direction can be staggered with the orthographic projection of the heating device 20 located at the upper side of the gas flow channel 11, or the orthographic projection of the heating device 20 located at the lower side of the gas flow channel 11 and staggered with the heating device 20 located at the upper side of the gas flow channel 11 along the second direction can be adjacent to the orthographic projection of the heating device 20 located at the upper side of the gas flow channel 11, or the orthographic projection of the heating device 20 located at the lower side of the gas flow channel 11 and staggered with the heating device 20 located at the upper side of the gas flow channel 11 along the second direction can partially overlap with the orthographic projection of the heating device 20 located at the upper side of the gas flow channel 11.

[0130] In the above technical solution, by at least partially staggering the heating device 20 located on one side of the gas flow channel 11 and the heating device 20 located on the other side of the gas flow channel 11 along the first direction, it is beneficial to increase the heating coverage area of ​​the multiple heating devices 20, and is more beneficial to improving the drying efficiency of the drying oven 100.

[0131] According to some embodiments of the present invention, the position of the heating device 20 is adjustable along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0132] Among them, the third direction is Figure 2The first direction, the second direction and the third direction are perpendicular to each other. The oven body 10 may be provided with a guide rail extending along the third direction, and the heating device 20 may be slidably mounted on the guide rail, so as to achieve an adjustable position of the heating device 20 along the third direction. The oven body 10 may also be provided with a lead screw, and the heating device 20 is formed with a threaded hole, the lead screw extends along the third direction and is inserted into the threaded hole, and the lead screw rotates to achieve an adjustable position of the heating device 20 along the third direction.

[0133] In the above technical solution, the position of the heating device 20 along the third direction is adjustable, and the position of the heating device 20 along the third direction can be adjusted according to actual heating needs. The heating device 20 can be adjusted to a suitable position, so that the heating device 20 can better heat the object 200 to be dried, which is beneficial to improving the drying efficiency of the object 200 to be dried.

[0134] According to some embodiments of the present invention, Figure 5 As shown, a partition 70 is provided in the oven body 10 , and the partition 70 is located between the heating device 20 and the gas flow channel 11 , and the partition 70 is constructed as a flow channel wall of the gas flow channel 11 , and a transparent portion 71 is formed on the partition 70 , and the transparent portion 71 corresponds to the corresponding heating device 20 .

[0135] The oven body 10 is provided with a partition 70, which is fixed to the oven body 10. Along the second direction, the partition 70 is located between the heating device 20 and the gas flow channel 11. The partition 70 is configured as a flow channel wall of the gas flow channel 11, and the partition 70 can separate the heating device 20 from the gas flow channel 11. As an example, Figure 5As shown, heating devices 20 are provided on both sides of the gas flow channel 11, and there are two partitions 70, one partition 70 is located between the upper heating device 20 and the gas flow channel 11, and the other partition 70 is located between the lower heating device 20 and the gas flow channel 11, and the two partitions 70 are both flow channel walls of the gas flow channel 11, and the gas flow channel 11 is located between the two partitions 70, one partition 70 is the flow channel wall of the first gas flow channel 112, and the other partition 70 is the flow channel wall of the second gas flow channel 113. The two partitions 70 can separate the gas flow channel 11 from the external space of the gas flow channel 11, so that the gas can flow more smoothly in the first gas flow channel 112 and the second gas flow channel 113, reduce the risk of slurry on the surface of the object 200 to be dried affecting the laser homogenizer, and facilitate the arrangement and maintenance of the heating device 20. In addition, the partition 70 separates the heating device 20 from the gas flow channel 11, so that the heating device 20 and the gas flow channel 11 are isolated. The hot water vapor generated by the heating device 20 heating the object 200 to be dried is carried away by the gas in the first gas flow channel 112 and the second gas flow channel 113 and discharged from the drying oven 100, thereby reducing the probability of the generated hot water vapor affecting the heating device 20, thereby extending the service life of the heating device 20 and reducing the maintenance cost of the drying oven 100.

[0136] The partition 70 is formed with a transparent portion 71, and the partition 70 may include transparent glass, and the transparent glass may be multiple, each transparent glass is configured as a transparent portion 71, and along the second direction, the transparent portion 71 is arranged corresponding to the corresponding heating device 20. When the heating device 20 is set as a light heating device 20, when the heating device 20 emits heating light toward the object 200 to be dried, the light can pass through the corresponding transparent portion 71 and act on the object 200 to be dried, thereby achieving the effect of heating and drying the object 200 to be dried.

[0137] In the above technical solution, the partition 70 is located between the heating device 20 and the gas flow channel 11, and the partition 70 is configured as the flow channel wall of the gas flow channel 11, so that the gas can flow more smoothly in the first gas flow channel 112 and the second gas flow channel 113, reducing the risk of the slurry on the surface of the object 200 to be dried affecting the laser homogenizer, which is beneficial to the arrangement and maintenance of the heating device 20, and reducing the probability of the generated hot water vapor affecting the heating device 20, thereby extending the service life of the heating device 20 and reducing the maintenance cost of the drying oven 100. A transparent portion 71 is formed by the partition 70. When the heating device 20 is set as a light heating device 20, when the heating device 20 emits heating light toward the object 200 to be dried, the light can pass through the corresponding transparent portion 71 and act on the object 200 to be dried, thereby achieving the effect of heating and drying the object 200 to be dried. In addition, when the heating device 20 is set as an electromagnetic heating device 20, the effect of heating and drying the object 200 to be dried can also be achieved.

[0138] According to some embodiments of the present invention, Figure 1 and Figure 5 As shown, the oven body 10 is formed with an observation window 91, through which the environment inside the oven body 10 can be observed, so that the user can understand the internal situation of the oven body 10. Further, the observation window 91 can be arranged corresponding to the gas flow channel 11, and the observation window 91 is a side wall of the gas flow channel 11, through which the drying situation of the object 200 to be dried in the gas flow channel 11 can be observed.

[0139] It should be noted that the drying oven 100 of the present invention has an oven body 10, and the oven body 10 is not provided with rollers supporting the object 200 to be dried, which can increase the internal space of the oven body 10, which is conducive to the uniform flow of gas in the gas flow channel 11, and one oven body 10 is easy to control without segmented scheduling.
