[0002] A dryer is a device that achieves drying by heating air or other media to evaporate moisture or solvents from wet materials. It is widely used in various fields, including industry, agriculture, and household applications, and comes in many different types with varying functions. The hot air circulation guide hood for dryers is particularly useful for guiding the flow of hot air and improving thermal efficiency.
[0003] According to research, due to cost constraints, parts far from the heating area are heated unevenly. Furthermore, after long-term use, material debris, dust, or condensation tend to accumulate inside the air guide, requiring regular disassembly and cleaning. Otherwise, it may block the air duct and affect the flow of hot air.
[0004] Therefore, a hot air circulation guide hood for a dryer is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example
[0022] As attached Figures 1 to 3 The diagram shows a hot air circulation guide hood for a dryer, comprising a guide hood 1, an air supply mechanism 2 installed below the guide hood 1, a support plate 3 installed between the guide hood 1 and the air supply mechanism 2, a storage chamber 4 installed above the support plate 3, an air inlet box 5 installed in the middle of the storage chamber 4, multiple filters 6 installed on both side walls of the air inlet box 5, a baffle plate 7 installed above the air inlet box 5, multiple air outlets 8 installed above the baffle plate 7, a guide plate 9 with an arc-shaped structure installed above the drying chamber 4, a circulating air pipe 20 installed above the guide hood 1, and an exhaust fan 10 installed inside the circulating air pipe 20 above the guide hood 1. One end of the circulating air pipe 20 is connected to the ventilation chamber 14. A drain pipe 11 is installed on the lower side of the guide hood 1. The air supply mechanism 2 drives hot air into the air inlet box 5. Impurities in the hot air are blocked by the filter screen 6. The clean hot air enters the interior of the storage chamber 4 to dry the goods. At the same time, the impurities are carried out by the wind and discharged from the top of the storage chamber 4. After being drawn into the circulating air pipe 20 by the exhaust fan 10, it enters the interior of the ventilation chamber 14 through the circulating air pipe 20 to complete the ventilation. After the drying operation is completed, during the gradual cooling process, the steam inside the guide hood 1 gradually condenses and flows to both sides of the storage chamber along the guide plate 9 and is discharged from the drain pipe 11.
[0023] A hot air inlet pipe 12 is installed on one side of the flow guide shroud 1. A blower 13 is installed on the side of the hot air inlet pipe 12 away from the flow guide shroud 1. An air exchange chamber 14 is installed on one side of the blower 13. A dryer 15 is installed on one side of the air exchange chamber 14. The dryer 15 generates heat when it works, which heats the air in the air exchange chamber 14. The hot air is driven into the hot air inlet pipe 12 by the blower 13 and is then input into the flow guide shroud 1 through the hot air inlet pipe 12, thereby raising the temperature inside the flow guide shroud 1.
[0024] The dryer 15 is a mature technology. This utility model mainly introduces the technology of the adapted flow guide shroud 1, so the dryer 15 will not be described in detail.
[0025] The surface of the flow guide 1 is equipped with two feed doors 16, which are symmetrically arranged about the central axis of the front of the flow guide 1. Two damping shafts 17 are installed on one side of the feed door 16, and the feed door 16 is rotatably connected to the flow guide 1 through the damping shafts 17. A door handle 18 is installed on the other side of the surface of the feed door 16, and the door handle 18 is connected to the feed door 16 by screws. The pulling force is applied to the door handle 18, which drives the door handle 18 to rotate. The rotation of the door handle 18 causes the feed door 16 to rotate and open along the damping shafts 17, so as to facilitate the entry and exit of goods into and out of the storage chamber 4.
[0026] The air supply mechanism 2 includes an air duct 201, a circulating fan 202, and a fixed base 203. One end of the air duct 201 is connected to a hot air inlet pipe 12, and the other end of the air duct 201 is connected to a heating chamber 19. Two circulating fans 202 are symmetrically installed on the body of the air duct 201. A fixed base 203 is installed below each of the circulating fans 202. The circulating fan 202 on the side closer to the hot air inlet pipe 12 rotates under the action of electricity. The rotation of the circulating fan 202 drives the hot air into the air duct 201. At the same time, the rotation of the circulating fan 202 on the other side draws the air in the heating chamber 19 into the air duct 201. This allows the hot air in the heating chamber 19 to circulate into the air duct 201 and mix with the hot air entering the air supply mechanism 2 through the hot air inlet pipe 12 before entering the air inlet box 5. This keeps the hot air in the heating chamber 19 flowing and evenly distributed around the storage room 4 for heating.
[0027] The storage chamber 4 is equipped with multiple storage panels 402, each with a mesh-like perforated structure. Both ends of each storage panel 402 have sliding grooves 401, allowing them to slide smoothly to the side walls of the storage chamber 4 and the air inlet box 5, respectively. The top of the storage chamber 4 is fitted with an inclined top plate 403, with the side of the top plate 403 closer to the air inlet box being higher than the side closer to the outside of the storage chamber 4. The mesh-like perforated structure of the storage panels 402 facilitates the upward flow of hot air from the bottom, accelerating drying while ensuring heating of the lower part. The storage panels 402 slide freely via the sliding grooves 401, making it easy to replace goods on them. The inclined structure of the top plate 403 facilitates the flow of condensate from above into the heating chamber.
[0028] Each shelf 402 has a filter screen 6 installed below it, and a baffle 7 is installed above the inside of the air inlet box 5. The baffle 7 separates the inside of the air inlet box 5. The mixed hot air entering the air inlet box 5 is filtered by the filter screen 6 and then enters the inside of the shelf 4, so that the temperature inside the shelf 402 is evenly distributed. At the same time, the hot air is gathered to the top of the shelf 4 under the obstruction of the baffle 7.
[0029] The air outlets 8 are installed between the top plate 403 and the baffle plate 7 and between the top plate 403 and the guide plate 9, respectively. The hot air gathered at the top of the storage chamber 4 re-enters the air inlet box 5 through the air outlets 8 between the top plate 403 and the baffle plate 7, and then enters the heating chamber 19 through the air outlets 8 between the top plate 403 and the guide plate 9, completing the hot air circulation inside the guide hood 1. This keeps the hot air flowing inside the entire guide hood 1, so that the temperature is evenly distributed inside and outside the heating chamber 19, ensuring that the goods are baked evenly while removing water vapor and impurities from the storage chamber 4.
[0030] The working process of this utility model is as follows: When in use, firstly, the dryer 15 generates heat to heat the air inside the ventilation chamber 14. At the same time, the blower 13 generates power under the action of electricity to drive the hot air into the hot air inlet pipe 12, and inputs the hot air into the guide hood 1 through the hot air inlet pipe 12, so that the temperature inside the guide hood 1 rises and heats the storage chamber 4, while drying the goods inside the storage chamber 4.
[0031] Then, the circulating fan 202 on the side near the hot air inlet pipe 12 rotates under the action of electricity. The rotation of the circulating fan 202 drives the hot air into the air guide pipe 201. At the same time, the circulating fan 202 on the other side rotates to draw the air in the heating chamber 19 into the air guide pipe 201. This causes the hot air in the heating chamber 19 to circulate into the air guide pipe 201 and mix with the hot air entering the air supply mechanism 2 through the hot air inlet pipe 12 before entering the air inlet box 5. At the same time, the hot air in the heating chamber 19 is kept flowing and evenly distributed around the storage room 4 for heating.
[0032] Secondly, the mixed hot air enters the storage chamber 4 through the filter screen 6 inside the air inlet box 5, which raises the internal temperature of the storage chamber 4 to heat the goods while filtering out impurities in the hot air. The hot air rises to the top of the storage chamber 4 through the storage plate 402 with a mesh hollow structure and enters the heating chamber 19 through the air outlet 8.
[0033] Finally, the exhaust fan 10 operates under the action of electricity to generate an upward airflow, which drives the hot air with water vapor discharged through the air outlet 8 into the circulating air pipe 20. The hot air enters the interior of the air exchange chamber 14 through the circulating air pipe 20 to complete the air exchange. After the drying operation is completed, the residual steam inside the guide hood 1 gradually condenses, flows along the guide plate 9 to both sides of the storage chamber 4, and is discharged from the drain pipe 11.
