[0002] A drying oven is a highly efficient and multifunctional drying equipment. Depending on the type of heat source and the application field, drying ovens can be divided into various types, such as air drying ovens, vacuum drying ovens, and microwave drying ovens. They are widely used in many industries such as food, chemical, pharmaceutical, printing and dyeing, textile, wood, and electronics.

[0027] like Figures 1-4 As shown, this utility model embodiment provides a high-efficiency and energy-saving drying oven, including a drying component 10. The top and interior of the drying component 10 are provided with an air intake and exhaust component 20. The air intake and exhaust component 20 includes a heat exchange pipe 21, an air inlet pipe 22, a telescopic pipe 23, a distributor 24, an air outlet 25, a fan 26, a heater 27, an exhaust pipe 28, and a partition 29.

[0028] One end of the heat exchange tube 21 is connected to an air inlet pipe 22, one end of the air inlet pipe 22 is connected to a telescopic pipe 23, and one end of the telescopic pipe 23 is connected to a distributor 24. Air outlets 25 are evenly distributed on the inner wall of the distributor 24. A fan 26 and a heater 27 are installed on the air inlet pipe 22. An exhaust pipe 28 is fixedly connected to the outer wall of the heat exchange tube 21, and baffles 29 are evenly fixedly connected to the inner wall of the exhaust pipe 28. The fan 26 blows air into the drying oven, which is then heated by the heater 27. Cold air is drawn into the drying oven through heat exchange tube 21, and hot air is discharged through exhaust tube 28. During exhaust, the hot air exchanges heat with the cold air in heat exchange tube 21, increasing the initial temperature of the cold air, thereby reducing heat loss and energy consumption of heater 27, and reducing the adverse environmental impact of hot air. The hot air is evenly delivered into the drying oven through distributor 24, drying the objects on the support 18 from multiple angles, shortening the drying time and improving drying efficiency. The hot air path during exhaust is extended through baffle 29, ensuring sufficient heat exchange.

[0029] In this embodiment, specifically: the drying assembly 10 includes a furnace body 11 and a furnace door 12;

[0030] Furnace doors 12 are symmetrically hinged to the front surface of furnace body 11, and furnace body 11 is closed through furnace doors 12.

[0031] In this embodiment, specifically: one end of the air inlet pipe 22 penetrates the inner wall of the furnace body 11, and the exhaust pipe 28 is connected to the top of the furnace body 11, through which hot air is discharged.

[0032] In this embodiment, specifically: a handle 13 is fixedly connected to the front surface of the furnace door 12, and the handle 13 facilitates opening and closing the furnace door 12.

[0033] In this embodiment, specifically: a control panel 14 is installed on the front surface of the furnace door 12, and the control panel 14 is used to control the operation of the drying furnace.

[0034] In this embodiment, specifically: support legs 15 are symmetrically and fixedly connected to the bottom of the furnace body 11, and the support legs 15 play a role in stabilizing and supporting.

[0035] In this embodiment, specifically: two electric guide rails 16 are symmetrically installed on the inner side wall of the furnace body 11. A slide table 17 is slidably connected to the top of the electric guide rail 16. A bracket 18 is fixedly connected to the top of the slide table 17. The slide table 17 is moved by the electric guide rail 16 so that the bracket 18 is close to the furnace door 12.

The slider 112 is fixedly connected to the outer sidewall of the distributor 24. When the motor 19 works, it drives the threaded rod 111 to rotate, causing the slider 112 and the distributor 24 to move downward, so that the distributor 24 covers the outside of the bracket 18.

[0037] In operation, this invention works as follows: the electric guide rail 16 drives the slide table 17 to move, bringing the support 18 closer to the oven door 12. The object to be dried is placed on the support 18, the oven door 12 is closed, the slide table 17 returns to its original position, the motor 19 drives the threaded rod 111 to rotate, causing the slider 112 and the distributor 24 to move downwards, so that the distributor 24 covers the outside of the support 18. The fan 26 blows air into the drying oven, and the air is heated by the heater 27. External cold air is drawn into the drying oven through the heat exchange tube 21, and hot air is discharged through the exhaust pipe 28. During exhaust, the hot air exchanges heat with the cold air in the heat exchange tube 21, increasing the initial temperature of the cold air, thereby reducing heat loss and the energy consumption of the heater 27, and reducing the adverse environmental impact of the hot air. The distributor 24 evenly delivers the hot air into the drying oven, drying the object on the support 18 from multiple angles, shortening the drying time and improving drying efficiency.
