Description

Technical Field

[0001] The present invention relates to the technical field of large baking equipment, and particularly relates to a baking device for intelligently adjusting temperature and humidity. Background Art

[0002] During the baking process of tobacco leaves, it is necessary to continuously adjust the temperature and humidity inside the baking device according to the baking progress to ensure the baking quality of the tobacco leaves. In terms of humidity adjustment of the current tobacco leaf baking device, it can draw in external air for dehumidification and heating and then use it for baking. However, during the yellowing stage of tobacco leaf baking, a certain humidity needs to be provided and maintained for a certain period of time to make the tobacco leaves turn yellow and become soft. When the humidity of the external air is too low, it is also necessary to manually pour water on the ground to increase the humidity. However, it is difficult to ensure the amount of water poured manually, making it very difficult to control the humidity. Moreover, the temperature in the baking room is relatively high, and there are certain safety hazards for people to enter and pour water. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a baking device for intelligently adjusting temperature and humidity to solve the above problems.

[0004] The technical solution of the present invention is realized as follows: A baking device for intelligently adjusting temperature and humidity includes:

[0005] A baking room, in which a uniform flow channel is provided above, and an anhydrous intelligent dry and wet bulb sensor for detecting the temperature and humidity inside the baking room is installed in the baking room;

[0006] A baking device, which includes a housing and a main fan, a humidity adjustment channel, a heating channel, a heat exchange device, and an exhaust duct provided inside the housing. The heat exchange device includes a first channel and a second channel that do not communicate with each other but can exchange heat. The main fan draws in external air and transports it through the humidity adjustment channel to the first channel for heat exchange. The air sent out from the first channel is heated through the heating channel and then sent into the baking room through the uniform flow channel. The baking room is connected to the inlet of the second channel through the exhaust duct, and the outlet of the second channel is connected to the outside. A water storage basin is provided in the humidity adjustment channel, a heating device is provided below the water storage basin, and an auxiliary fan for sending the air flow from the exhaust duct into the second channel is provided in the exhaust duct.

[0007] By adopting the above technical solution, when it is necessary to bake and dehumidify the inside of the baking room, dry and hot air is sent into the baking room, and fresh air is sent into the humidity adjustment channel through the main fan. The fresh air is dehumidified and dried through the humidity adjustment channel to obtain dry fresh air, which then enters the first channel of the heat exchange device. After being preheated and warmed through the heat exchange device, it enters the heating channel to be warmed again to reach the required temperature, obtaining dry and hot air. Finally, it is sent into the baking room through the uniform flow channel for use. The air after baking is turned into hot and humid air and enters the second channel of the heat exchange device through the exhaust pipe to preheat the fresh air in the first channel, obtaining wet and warm air, effectively improving the utilization efficiency of heat, and finally being discharged to the outside;

[0008] When it is necessary to bake and moisturize the inside of the baking room, hot and humid air is sent into the baking room. First, fresh air is sent into the humidity adjustment channel through the main fan. By heating, the water in the water storage basin is accelerated to evaporate into water vapor, thereby increasing the humidity of the fresh air passing through the humidity adjustment channel to obtain moist fresh air. Then, it is preheated through the first channel of the heat exchange device and enters the heating channel to be warmed again to obtain hot and humid air. Finally, it is sent into the baking room through the uniform flow channel for use; it can not only provide dry and hot air in the baking room to quickly dry the tobacco leaves during baking, but also provide hot and humid air with a certain humidity during the yellowing stage of tobacco leaf baking, enabling the tobacco leaves to effectively turn yellow and become soft, eliminating the need for manual humidification operation. The waterless intelligent wet and dry bulb sensor can accurately detect the temperature and humidity in the baking room, thereby adjusting the temperature and humidity according to different baking degrees, making it more intelligent, convenient, and safe.

[0009] The present invention is further configured as: The baking equipment further includes:

[0010] The first semiconductor refrigeration sheet group, and the first semiconductor refrigeration sheet group is embedded and installed on the first partition board;

[0011] The second semiconductor refrigeration sheet group, and the second semiconductor refrigeration sheet group is embedded and installed on the second partition board. The water storage basin is arranged on the upper side of the second semiconductor refrigeration sheet group and directly below the first semiconductor refrigeration sheet group;

[0012] The heater, and the heater is arranged downstream in the heating channel for heating the air flow in the heating channel;

[0013] Among them, both the first semiconductor refrigeration chip group and the second semiconductor refrigeration chip group include multiple semiconductor refrigeration chips arranged in parallel. The heating sides of the semiconductor refrigeration chips on the first semiconductor refrigeration chip group and the second semiconductor refrigeration chip group are all arranged upwards, and the refrigeration sides are all arranged downwards. The first partition board and the second partition board are both horizontally arranged, and the second partition board is arranged below the first partition board. The heating channel is arranged between the upper inner wall of the housing and the first partition board, the humidity adjustment channel is arranged between the first partition board and the second partition board, and the heat exchange device is arranged on one side of the humidity adjustment channel and the heating channel.

[0014] By adopting the above technical solution, when baking and dehumidifying in the baking room, the first semiconductor refrigeration chip group is started, and the second semiconductor refrigeration chip group is not started. Therefore, the fresh air entering the humidity adjustment channel contacts the refrigeration side of the first semiconductor refrigeration chip group, so that the water vapor in the fresh air condenses and drips into the water storage basin below for collection, effectively dehumidifying the fresh air. The condensed and dried fresh air enters the heat exchange device for preheating and temperature increase. When entering the heating channel, the heating side of the first semiconductor refrigeration chip group and the heater heat the air to reach the required temperature, so as to provide dry and hot air in the baking room.

[0015] When baking and moisturizing in the baking room, the first semiconductor refrigeration chip group is not started, and the second semiconductor refrigeration chip group is started, so that the heating side of the second semiconductor refrigeration chip group heats the water in the water storage basin, thereby accelerating the evaporation of the water and increasing the humidity of the air passing through the humidity adjustment channel. The humidified fresh air enters the heat exchange device for preheating and temperature increase, and then enters the heating channel to reach the required temperature through the heater, so as to provide humid and hot air in the baking room. The refrigeration side of the second semiconductor refrigeration chip group can also effectively help the main fan and the controller cool down during operation; both the refrigeration side and the heating side of the semiconductor refrigeration chip can be effectively utilized, improving the energy utilization efficiency, and the structure is more compact and small.

[0016] The present invention is further configured as: heat conduction sheets are arranged on both the upper and lower sides of the first semiconductor refrigeration chip group and the lower side of the second semiconductor refrigeration chip group, and the vertical projection of the heat conduction sheet on the lower side of the first semiconductor refrigeration chip group falls within the water storage basin.

[0017] By adopting the above technical solution, the heat conduction sheet can effectively increase the contact area between both sides of the semiconductor refrigeration chip and the air, thereby improving the heat exchange efficiency. The heat conduction sheet on the lower side of the first semiconductor refrigeration chip group can effectively condense and dry the air, and the condensed water drops into the water storage basin for collection for use when humidifying.

[0018] The present invention is further configured such that: an equipment chamber is provided between the second partition plate and the lower inner wall of the housing, the main blower is arranged in the equipment chamber, an air outlet pipe on the main blower passes upward through the second partition plate for sending fresh air into the humidity adjustment channel, and a one-way valve that only allows air to flow upward into the humidity adjustment channel is provided in the air outlet pipe.

[0019] By adopting the above technical solution, when the second semiconductor refrigeration chip group is started, its refrigeration side can effectively cool down the equipment chamber, thereby cooling down the main blower and the controller in the equipment chamber. The one-way valve can effectively prevent the air flow from flowing backward out of the air outlet pipe when the main blower is not started.

[0020] The present invention is further configured such that: the heat exchange device includes:

[0021] A heat exchange tube group, there are two heat exchange tube groups which are arranged at intervals up and down. The heat exchange tube group includes a plurality of heat exchange tubes, gaps are provided between adjacent heat exchange tubes, and a first channel is formed in the heat exchange tubes;

[0022] A third partition plate, the third partition plate is vertically arranged on the upper side of the second partition plate and is connected to the two side walls and the upper inner wall of the housing to form a second channel;

[0023] A guide plate, the inner wall of the guide plate is arc-shaped, the guide plate is fixedly installed on the outside of the housing to form a guide cavity, and a heat insulation and heat preservation layer is provided on the inner wall of the guide plate;

[0024] Wherein, both of the two heat exchange tube groups are arranged in the second channel, the two ends of the heat exchange tube group respectively pass through the third partition plate and the housing, one end of the lower heat exchange tube group passes through the third partition plate and is communicated with the humidity adjustment channel, one end of the upper heat exchange tube group passes through the third partition plate and is communicated with the heating channel, the inner wall of the guide plate faces the end where the heat exchange tube group extends out of the housing, the air flow sent out from the first channel of the lower heat exchange tube group is guided through the guide cavity into the first channel of the upper heat exchange tube group, an air outlet connected to the second channel is opened at the top end of the housing, a filtering device is provided at the air outlet, and the exhaust pipe passes through the second partition plate and is communicated with the second channel.

[0025] By adopting the above technical solution, the air flow in the humidity adjustment channel enters the first channel of the heat exchange tubes in the lower heat exchange tube group, and then enters the guiding cavity. It is guided to flow upward through the guiding plate and thus enters the first channel of the heat exchange tubes in the upper heat exchange tube group. Meanwhile, the exhaust duct sends the air in the baking room into the second channel between the third partition plate and the housing. The heat exchange tube group preheats the air in the first channel. By arranging two heat exchange tube groups up and down, the heat exchange distance and time are effectively increased, making the heat exchange more sufficient. The air flowing out from the upper heat exchange tube group enters the heating channel for heating to reach the required temperature. The air in the second channel is cooled after preheating by the heat exchange tube group and blown out from the air outlet. The filtering device can effectively prevent external impurities and dust from entering the second channel.

[0026] The present invention is further arranged as follows: a plurality of the heat exchange tubes are arranged horizontally side by side to form a heat exchange tube layer, and a plurality of the heat exchange tube layers are arranged in multiple layers up and down to form a heat exchange tube group. There are gaps between adjacent heat exchange tubes and heat exchange tube layers. In adjacent heat exchange tube layers, the heat exchange tubes in the upper heat exchange tube layer are located directly above the middle gap between two adjacent heat exchange tubes in the lower heat exchange tube layer.

[0027] By adopting the above technical solution, the air in the second channel flows from bottom to top. Therefore, the air flow will flow upward through the middle gap between two adjacent heat exchange tubes and contact the heat exchange tubes in the upper heat exchange tube layer, thereby increasing the contact area between the air flow and the heat exchange tubes, improving the heat exchange efficiency, and making the heat utilization rate higher.

[0028] The present invention is further arranged as follows: the heat exchange device further includes:

[0029] A diversion hole, which is opened on the side wall of the housing and is located between the two heat exchange tube groups. The second channel is communicated with the guiding cavity through the diversion hole;

[0030] A sealing and diversion mechanism, which is arranged between the two heat exchange tube groups. The sealing and diversion mechanism includes a plurality of diversion plates arranged side by side. The upper ends on both sides of the diversion plate are rotationally connected to the inside of the housing through rotating shafts. When the diversion plate is vertically arranged, the leftmost diversion plate is arranged in the diversion hole and seals the diversion hole. The plurality of diversion plates are driven by a first driving device to rotate in the same direction. After the plurality of diversion plates rotate, they abut against each other to separate and seal the second channel between the two heat exchange tube groups and open the diversion hole.

[0031] By adopting the above technical solution, when baking and dehumidifying in the baking room, the sealing and guiding mechanism seals the guiding holes, closes the guiding holes, and the air flow in the second channel flows upward between adjacent guiding plates and blows out from the air outlet. At this time, the guiding cavity is not connected to the second channel but only to the first channel;

[0032] When baking and moisturizing in the baking room, first start the main fan and the second semiconductor refrigeration chip group to send humid and hot air into the baking room. When the humidity of the air sent into the baking room reaches the required level, turn off the main fan and the second semiconductor refrigeration chip group, and drive multiple guiding plates to rotate in the same direction by the first driving device, so that the guiding plates are connected end to end, thereby separating and sealing the second channel between the two heat exchange tube groups and opening the guiding holes. At this time, the air flow sent by the exhaust duct passes through the second channel at the lower heat exchange tube group and is blocked by the rotated guiding plates and guided to pass through the guiding holes into the guiding cavity. Due to the function of the one-way valve in the air outlet pipe, the air flow cannot enter the humidity adjustment channel through the first channel of the lower heat exchange tube group. Therefore, the air flow in the guiding cavity will enter the first channel of the upper heat exchange tube group upward and then enter the heating channel for heating, so that the air flow can maintain a certain humidity and circulate between the baking room and the baking equipment without communicating with the external air, effectively reducing energy consumption.

[0033] The present invention is further provided that: the horizontal heights of the rotating shafts of the multiple guiding plates gradually decrease from left to right, the lower end surfaces of the multiple guiding plates are at the same horizontal height, when the guiding plates are vertically arranged, the distance between adjacent two guiding plates gradually decreases from left to right, and the distance between adjacent two guiding plates is less than the height of the guiding plate on its left side.

[0034] By adopting the above technical solution, after the guiding plates rotate, they can be connected end to end, and the guiding plate farther away from the guiding hole rotates at a smaller angle, so that the bending angle of the side farther away from the guiding hole is larger after multiple guiding plates are abutted, thereby effectively guiding the air flow to the left side, and at the same time, the upward flowing air flow can effectively press the lower end of the left guiding plate against the upper end side of the right guiding plate, making the abutment between adjacent two guiding plates tighter.

[0035] The present invention is further provided that: the height of the leftmost guiding plate is greater than the height of the guiding hole, a first notch for the lower end of the leftmost guiding plate to abut is provided at the lower side near the end of the second channel of the guiding hole, and a second notch for the lower end of the rightmost guiding plate to abut and seal after rotation is provided on the inner wall of the third partition plate facing the second channel.

[0036] By adopting the above technical solution, when the deflector is in the vertical state, the lower end of the leftmost deflector abuts against the first notch, thereby sealing the deflector hole, making the sealing effect between the leftmost deflector and the deflector hole better; when the deflector rotates, the lower end of the rightmost deflector abuts against the second notch, making the partitioning and sealing effect of the deflector on the second channel better.

[0037] The present invention is further configured as: The first driving device includes:

[0038] A pulley, the number of the pulleys is the same as the number of the deflectors, at least two grooves for connecting a belt are provided on the outer wall of the pulley, the diameters of the grooves on the same pulley are the same, adjacent pulleys are connected by belt transmission, and the diameters of the grooves on the multiple pulleys gradually increase from left to right, so that the rotation angles of the multiple deflectors gradually decrease from left to right after rotation and the adjacent deflectors abut and seal against each other, and one end of the rotating shaft passes through the housing and extends outwards to be connected with the pulley;

[0039] A protective cover, the protective cover covers the outside of the pulley, and the protective cover is fixed on the housing;

[0040] A first motor, the first motor is in transmission connection with any one of the pulleys.

[0041] By adopting the above technical solution, the first motor drives one of the pulleys to rotate, so that all the pulleys can rotate in the same direction, and all the deflectors rotate in the same direction. Since the pulleys are connected by belt transmission, the circumferences of each pulley rotation are the same, so that the pulley with a smaller groove diameter rotates at a larger angle, realizing that the bending angle of the side of the multiple deflectors farther away from the deflector hole after abutting is larger, and the air flow guiding effect is better. The protective cover can effectively wrap the pulley and make it safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0060] As Figures 1 - 16 shown, the present invention discloses a baking device for intelligently adjusting temperature and humidity, including

[0061] a baking room 1, in which a uniform flow channel 10 is provided above the baking room 1, and a waterless intelligent wet and dry bulb sensor 11 for detecting the temperature and humidity in the baking room 1 is installed in the baking room 1;

[0062] a baking device 2, which includes a housing 20, a main fan 3, a humidity adjustment channel 21, a heating channel 22, a heat exchange device 23, and an exhaust duct 4 provided in the housing 20. The heat exchange device 23 includes a first channel 230 and a second channel 231 that do not communicate with each other but can exchange heat. The main fan 3 draws in external air and transports it through the humidity adjustment channel 21 to the first channel 230 for heat exchange. The air sent out from the first channel 230 is heated in the heating channel 22 and then sent into the baking room 1 through the uniform flow channel 10. The baking room 1 is connected to the inlet of the second channel 231 through the exhaust duct 4, and the outlet of the second channel 231 is connected to the outside. A water storage basin 24 is provided in the humidity adjustment channel 21, and a heating device is provided below the water storage basin 24. A sub-fan 5 for sending the air flow from the exhaust duct 4 into the second channel 231 is provided in the exhaust duct 4.

[0063] By adopting the above technical solutions, when baking and dehumidifying the baking room 1, that is, sending dry and hot air into the baking room 1, fresh air is sent into the humidity adjustment channel 21 through the main fan 3. The fresh air is dehumidified and dried through the humidity adjustment channel 21 to obtain dry fresh air, and then enters the first channel 230 of the heat exchange device 23. After being preheated and heated through the heat exchange device 23, it enters the heating channel 22 for further heating to reach the required temperature, obtaining dry and hot air. Finally, it is sent into the baking room 1 through the uniform flow channel 10 for use. The air after baking becomes hot and humid air and enters the second channel 231 of the heat exchange device 23 through the exhaust duct 4 to preheat the fresh air in the first channel 230, obtaining wet and warm air, effectively improving the heat utilization efficiency, and finally discharging it to the outside;

[0064] When it is necessary to bake and moisturize the inside of the baking room 1, that is, send humid and hot air into the baking room 1. First, send fresh air into the humidity adjustment channel 21 through the main fan 3, and accelerate the evaporation of the water in the water storage basin 24 into water vapor by heating, so as to increase the humidity of the fresh air passing through the humidity adjustment channel 21, and obtain moist fresh air. Then, preheat it through the first channel 230 of the heat exchange device 23, and enter the heating channel 22 for reheating to obtain humid and hot air. Finally, send it into the baking room 1 through the uniform flow channel 10 for use; it can not only provide dry and hot air in the baking room 1 to quickly dry the tobacco leaves during baking, but also provide humid and hot air with a certain humidity during the yellowing stage of tobacco leaf baking, so that the tobacco leaves can effectively turn yellow and become soft, without manual humidification operation. The waterless intelligent wet and dry bulb sensor 11 can accurately detect the temperature and humidity in the baking room 1, and thus adjust the temperature and humidity according to different baking degrees, making it more intelligent, convenient and safe.

[0065] In the embodiment of the present invention, the baking device 2 further includes:

[0066] The first semiconductor refrigeration chip group 25, and the first semiconductor refrigeration chip group 25 is embedded and installed on the first partition plate 200;

[0067] The second semiconductor refrigeration chip group 26, and the second semiconductor refrigeration chip group 26 is embedded and installed on the second partition plate 201. The water storage basin 24 is arranged on the upper side of the second semiconductor refrigeration chip group 26 and directly below the first semiconductor refrigeration chip group 25;

[0068] The heater 29, and the heater 29 is arranged downstream in the heating channel 22 for heating the air flow in the heating channel 22;

[0069] Wherein, both the first semiconductor refrigeration chip group 25 and the second semiconductor refrigeration chip group 26 include a plurality of semiconductor refrigeration chips arranged in parallel. The heating sides of the semiconductor refrigeration chips on the first semiconductor refrigeration chip group 25 and the second semiconductor refrigeration chip group 26 are all arranged upward, and the refrigeration sides are all arranged downward. The first partition plate 200 and the second partition plate 201 are both horizontally arranged. The second partition plate 201 is arranged below the first partition plate 200. The heating channel 22 is arranged between the upper inner wall of the housing 20 and the first partition plate 200. The humidity adjustment channel 21 is arranged between the first partition plate 200 and the second partition plate 201. The heat exchange device 23 is arranged on one side of the humidity adjustment channel 21 and the heating channel 22.

[0070] By adopting the above technical solution, when baking and dehumidifying the baking room 1, the first semiconductor refrigeration chip group 25 is started, and the second semiconductor refrigeration chip group 26 is not started. Therefore, the fresh air entering the humidity adjustment channel 21 contacts the refrigeration side of the first semiconductor refrigeration chip group 25, so that the water vapor in the fresh air condenses and drips into the water storage basin 24 below for collection, effectively dehumidifying the fresh air. The fresh air after condensation and drying enters the heat exchange device 23 for preheating and temperature increase. When entering the heating channel 22, the heating side of the first semiconductor refrigeration chip group 25 and the heater 29 heat the air to make it reach the required temperature, so as to provide dry and hot air for the baking room 1.

[0071] When baking and moisturizing the baking room 1, the first semiconductor refrigeration chip group 25 is not started, and the second semiconductor refrigeration chip group 26 is started. The heating side of the second semiconductor refrigeration chip group 26 heats the water in the water storage basin 24, thereby accelerating the evaporation of the water and increasing the humidity of the air passing through the humidity adjustment channel 21. The fresh air after humidification enters the heat exchange device 23 for preheating and temperature increase, and then enters the heating channel 22 to reach the required temperature through the heater 29, so as to provide wet and hot air for the baking room 1. The refrigeration side of the second semiconductor refrigeration chip group 26 can also effectively help the main fan 3 and the controller to cool down during operation; both the refrigeration side and the heating side of the semiconductor refrigeration chip can be effectively utilized, improving the energy utilization efficiency, and the structure is more compact and small.

[0072] In the embodiment of the present invention, heat conduction sheets 28 are provided on both the upper and lower sides of the first semiconductor refrigeration chip group 25 and the lower side of the second semiconductor refrigeration chip group 26, and the vertical projection of the heat conduction sheet 28 on the lower side of the first semiconductor refrigeration chip group 25 falls within the water storage basin 24.

[0073] By adopting the above technical solution, the heat conduction sheet 28 can effectively increase the contact area between both sides of the semiconductor refrigeration chip and the air, thereby improving the heat exchange efficiency. The heat conduction sheet 28 on the lower side of the first semiconductor refrigeration chip group 25 can effectively condense and dry the air, and the condensed water drops into the water storage basin 24 for collection and use when humidifying.

[0074] In the embodiment of the present invention, an equipment cavity 27 is provided between the second partition plate 201 and the lower inner wall of the housing 20. The main fan 3 is arranged in the equipment cavity 27. The air outlet pipe 30 on the main fan 3 passes upward through the second partition plate 201 for sending fresh air into the humidity adjustment channel 21, and a one-way valve 31 that only allows air to flow upward into the humidity adjustment channel 21 is provided in the air outlet pipe 30.

[0075] By adopting the above technical solution, when the second semiconductor refrigeration chip group 26 is started, its refrigeration side can effectively cool the equipment cavity 27, thereby cooling down the main fan 3 and the controller in the equipment cavity 27. The one-way valve 31 can effectively prevent the air flow from flowing back out through the air outlet pipe 30 when the main fan 3 is not started.

[0076] In an embodiment of the present invention, the heat exchange device 23 includes:

[0077] A heat exchange tube group 232, there are two heat exchange tube groups 232 which are arranged at intervals up and down. The heat exchange tube group 232 includes a plurality of heat exchange tubes, and there are gaps between adjacent heat exchange tubes. A first channel 230 is formed in the heat exchange tubes;

[0078] A third partition plate 233, the third partition plate 233 is vertically arranged on the upper side of the second partition plate 201 and is connected to the two side walls and the upper inner wall of the housing 20 to form a second channel 231;

[0079] A guide plate 234, the inner wall of the guide plate 234 is arc-shaped. The guide plate 234 is fixedly installed on the outside of the housing 20 to form a guide cavity 2340. An insulating and heat-preserving layer is provided on the inner wall of the guide plate 234;

[0080] Among them, both heat exchange tube groups 232 are arranged in the second channel 231. The two ends of the heat exchange tube group 232 respectively pass through the third partition plate 233 and the housing 20. One end of the lower heat exchange tube group 232 passes through the third partition plate 233 and is connected to the humidity adjustment channel 21, and one end of the upper heat exchange tube group 232 passes through the third partition plate 233 and is connected to the heating channel 22. The inner wall of the guide plate 234 faces the end where the heat exchange tube group 232 extends out through the housing 20. The air flow sent out from the first channel 230 of the lower heat exchange tube group 232 is guided through the guide cavity 2340 into the first channel 230 of the upper heat exchange tube group 232. An air outlet communicating with the second channel 231 is opened at the top end of the housing 20, and a filtering device 202 is provided at the air outlet. The exhaust pipe 4 passes through the second partition plate 201 and is connected to the second channel 231.

[0081] By adopting the above technical solution, the air flow in the humidity adjustment channel 21 enters the first channel 230 of the heat exchange tubes of the lower heat exchange tube group 232, then enters the guiding cavity 2340, and is guided by the guiding plate 234 to flow upward and thus enters the first channel 230 of the heat exchange tubes of the upper heat exchange tube group 232. At the same time, the exhaust duct 4 sends the air in the baking room 1 into the second channel 231 between the third partition plate 233 and the housing 20, and the heat exchange tube group 232 preheats the air in the first channel 230. By arranging two heat exchange tube groups 232 up and down, the heat exchange distance and time are effectively increased, making the heat exchange more sufficient. The air flowing out of the upper heat exchange tube group 232 enters the heating channel 22 for heating to reach the required temperature; the air in the second channel 231 is cooled after preheating the heat exchange tube group 232 and is blown out from the air outlet, and the filtering device 202 can effectively prevent external impurities and dust from entering the second channel 231.

[0082] In the embodiment of the present invention, a plurality of the heat exchange tubes are arranged horizontally in parallel to form a heat exchange tube layer, and a plurality of the heat exchange tube layers are arranged in multiple layers up and down to form the heat exchange tube group 232. There are gaps between adjacent heat exchange tubes and heat exchange tube layers. In adjacent heat exchange tube layers, the heat exchange tubes in the upper heat exchange tube layer are directly above the middle gaps between two adjacent heat exchange tubes in the lower heat exchange tube layer.

[0083] By adopting the above technical solution, the air in the second channel 231 flows from bottom to top, so the air flow will flow upward through the middle gaps between two adjacent heat exchange tubes and contact the heat exchange tubes in the upper heat exchange tube layer, thereby increasing the contact area between the air flow and the heat exchange tubes, improving the heat exchange efficiency, and making the heat utilization rate higher.

[0084] In the embodiment of the present invention, the heat exchange device 23 further includes:

[0085] Flow guiding holes 203, which are opened on the side wall of the housing 20 and are located between the two heat exchange tube groups 232, and the second channel 231 is communicated with the guiding cavity 2340 through the flow guiding holes 203;

[0086] A sealed flow guide mechanism is provided between the two heat exchange tube groups 232. The sealed flow guide mechanism includes a plurality of guide plates 235 arranged in parallel. The upper ends of the guide plates 235 are rotatably connected to the shell 20 through a rotating shaft 2350. When the guide plates 235 are arranged vertically, the leftmost guide plate 235 is arranged in the guide hole 203 and seals the guide hole 203. The plurality of guide plates 235 are driven to rotate in the same direction by a first driving device. After rotation, the plurality of guide plates 235 abut against each other, thereby separating and sealing the second channel 231 between the two heat exchange tube groups 232 and opening the guide hole 203.

[0087] By adopting the above technical solution, when baking and dehumidifying the baking room 1, the sealing guide mechanism seals the guide hole 203, closing the guide hole 203. The airflow in the second channel 231 flows from bottom to top through the adjacent guide plates 235 and is blown out from the air outlet. At this time, the guide cavity 2340 is not connected to the second channel 231 but is connected to the first channel 230.

[0088] When baking and moisturizing the baking room 1, the main fan 3 and the second semiconductor refrigeration plate group 26 are first started to send hot and humid air into the baking room 1. When the humidity of the air sent into the baking room 1 reaches the required level, the main fan 3 and the second semiconductor refrigeration plate group 26 are turned off, and the first driving device drives the multiple guide plates 235 to rotate in the same direction, so that the guide plates 235 are connected end to end, thereby separating and sealing the second channel 231 between the two heat exchange tube groups 232 and opening the guide hole 203. At this time, the air flow sent in by the exhaust pipe 4 passes through the second channel 231 at the lower heat exchange tube group 232. After 31, the rotated guide plate 235 is blocked and guided to pass through the guide hole 203 and enter the guide cavity 2340. Due to the action of the one-way valve 31 in the air outlet pipe 30, the airflow cannot pass through the first channel 230 of the heat exchange tube group 232 below to enter the humidity regulating channel 21. Therefore, the airflow in the guide cavity 2340 will go upward into the first channel 230 of the heat exchange tube group 232 above, and then enter the heating channel 22 for heating, so that the airflow can maintain a certain humidity and circulate between the baking room 1 and the baking equipment 2 without communicating with the external air, thereby effectively reducing energy consumption.

[0089] In an embodiment of the present invention, the horizontal height of the rotating shaft 2350 of the multiple guide plates 235 gradually decreases from left to right, and the lower end surfaces of the multiple guide plates 235 are at the same horizontal height. When the guide plates 235 are vertically arranged, the distance between two adjacent guide plates 235 gradually decreases from left to right, and the distance between two adjacent guide plates 235 is smaller than the height of the guide plate 235 on its left.

[0090] By adopting the above technical solution, after the deflector 235 rotates, it can end to end, and the farther the deflector 235 is from the diversion hole 203, the smaller the rotation angle thereof, so that the farther the side of the plurality of deflectors 235 abuts from the diversion hole 203, the greater the bending angle, thereby effectively guiding the air flow to the left side, and at the same time, the upward flowing air flow can effectively press the lower end of the left deflector 235 against the upper end side of the right deflector 235, making the abutment between adjacent two deflectors 235 closer.

[0091] In the embodiment of the present invention, the height of the leftmost deflector 235 is greater than the height of the diversion hole 203. A first notch 2030 for the lower end of the leftmost deflector 235 to abut is provided at one end of the lower side of the diversion hole 203 close to the second channel 231. A second notch 2330 for the lower end of the rightmost deflector 235 to abut and be sealed after rotation is provided on the inner wall of the third partition 233 facing the second channel 231.

[0092] By adopting the above technical solution, when the deflector 235 is in the vertical state, the lower end of the leftmost deflector 235 abuts in the first notch 2030, thereby sealing the diversion hole 203 and making the sealing effect between the leftmost deflector 235 and the diversion hole 203 better; when the deflector 235 rotates, the lower end of the rightmost deflector 235 abuts in the second notch 2330, making the partitioning and sealing effect of the deflector 235 on the second channel 231 better.

[0093] In the embodiment of the present invention, the first driving device includes:

[0094] A pulley 236. The number of the pulleys 236 is the same as the number of the deflectors 235. At least two grooves 2361 for connecting the belt 2360 are provided on the outer wall of the pulley 236. The diameters of the grooves 2361 on the same pulley 236 are the same. Adjacent two pulleys 236 are driven and connected by the belt 2360. The diameters D of the grooves 2361 on the plurality of pulleys 236 gradually increase from left to right, so that the rotation angles of the plurality of deflectors 235 gradually decrease from left to right after rotation and adjacent deflectors 235 abut and seal. One end of the rotating shaft 2350 passes through the housing 20 and extends outwards to be connected with the pulley 236;

[0095] A protective cover 237. The protective cover 237 covers the outside of the pulley 236, and the protective cover 237 is fixed on the housing 20;

[0096] A first motor 238. The first motor 238 is drivingly connected with any one of the pulleys 236.

[0097] By adopting the above technical solution, the first motor 238 drives one of the pulleys 236 to rotate, so that all the pulleys 236 can rotate in the same direction, so that all the guide plates 235 can rotate in the same direction. Since the pulleys 236 are connected by belts 2360, the circumference of each pulley 236 is the same, so that the pulley 236 with a smaller diameter of the groove 2361 has a larger rotation angle, so that after multiple guide plates 235 abut, the bending angle of the side farther away from the guide hole 203 is larger, which has a better effect on guiding the airflow. The protective cover 237 can effectively wrap the pulley 236 to make it safer.

[0098] In an embodiment of the present invention, the flow balancing channel 10 includes:

[0099] An upper side wall 100 , wherein the upper side wall 100 gradually approaches the lower side wall 101 from left to right through a plurality of downwardly inclined upper inclined portions 103 ;

[0100] A lower side wall 101 is provided with a plurality of vertically downwardly arranged outflow pipes 1010, and a swinging mechanism 105 for changing the wind direction is provided in the outflow pipes 1010;

[0101] The baffle 102 is provided between the upper side wall 100 and the lower side wall 101 and is connected to the side of the outflow pipe 1010 away from the baking device 2. The baffle 102 is parallel to the upper side wall 100 and the lower side wall 101. The number of the baffles 102 is the same as the number of the outflow pipes 1010. The connection between the baffle 102 and the outflow pipe 1010 is connected to the lower side wall 101 via a lower inclined portion 104;

[0102] Among them, an inlet 106 connected to the downstream of the heating channel 22 is provided between the left sides of the upper side wall 100 and the lower side wall 101, the upper inclined portion 103 and the lower inclined portion 104 are parallel and have the same length, and the lower inclined portion 104 is provided directly below the upper inclined portion 103.

[0103] By adopting the above technical solution, the airflow delivered by the heating channel 22 enters the inlet 106. As the airflow flows in the uniform flow channel 10, a part of the airflow is separated by the baffle 102 and blown downward through the outflow pipe 1010. Under the action of the upper side wall 100, the inner diameter of the flow channel gradually decreases, so that the airflow blown out by each outflow pipe 1010 is the same size. The airflow delivered by the heating channel 22 can be evenly blown into the baking room 1, making the airflow more uniform and the baking effect of the tobacco leaves more uniform.

[0104] In an embodiment of the present invention, the swinging plate mechanism 105 includes:

[0105] The left swing piece 1050, a left guiding piece 1051 is provided at the top end of the left swing piece 1050, and a left rotating shaft 1052 is provided at the connection between the left swing piece 1050 and the left guiding piece 1051;

[0106] The middle swing piece 1053, a middle guiding piece 1054 is provided at the top end of the middle swing piece 1053, and a middle rotating shaft 1055 is provided at the connection between the middle swing piece 1053 and the middle guiding piece 1054;

[0107] The right swing piece 1056, a right guiding piece 1057 is provided at the top end of the right swing piece 1056, and a right rotating shaft 1058 is provided at the connection between the right swing piece 1056 and the right guiding piece 1057;

[0108] The connecting rod 1059;

[0109] The second driving device 107, the second driving device 107 is used to drive the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 to rotate in the same direction;

[0110] Wherein, the middle swing piece 1053 is arranged between the left swing piece 1050 and the right swing piece 1056, the left guiding piece 1051, the middle guiding piece 1054 and the right guiding piece 1057 are connected by the connecting rod 1059, the left rotating shaft 1052, the middle rotating shaft 1055 and the right rotating shaft 1058 are on the same horizontal line and are rotatably connected in the outflow pipe 1010, and the lengths of the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 are the same; when the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 rotate towards the left, the included angle β1 between the left swing piece 1050 and the outlet of the outflow pipe 1010 is greater than the included angle β2 between the middle swing piece 1053 and the outlet of the outflow pipe 1010, and the included angle β2 between the middle swing piece 1053 and the outlet of the outflow pipe 1010 is greater than the included angle β3 between the right swing piece 1056 and the outlet of the outflow pipe 1010; when the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 rotate towards the right, the included angle γ3 between the right swing piece 1056 and the outlet of the outflow pipe 1010 is greater than the included angle γ2 between the middle swing piece 1053 and the outlet of the outflow pipe 1010, and the included angle γ2 between the middle swing piece 1053 and the outlet of the outflow pipe 1010 is greater than the included angle γ1 between the left swing piece 1050 and the outlet of the outflow pipe 1010.

[0111] By adopting the above technical solution, when the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 are vertically downward, the wind blows vertically downward perpendicular to the outflow pipe 1010;

[0112] When the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 rotate towards the left, the lower end of the left swing piece 1050 is lower than the lower end of the middle swing piece 1053 which is lower than the horizontal height of the lower end of the right swing piece 1056. A gradually narrowing space is formed between the left side of the left swing piece 1050 and the left inner wall of the outflow pipe 1010, making the air more concentrated and flowing faster when passing through. Therefore, when blowing to the left, the wind can be effectively blown farther and over a larger range.

[0113] Similarly, when the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 rotate towards the right, the lower end of the right swing piece 1056 is lower than the lower end of the middle swing piece 1053 which is lower than the horizontal height of the lower end of the left swing piece 1050. A gradually narrowing space is formed between the right side of the right swing piece 1056 and the right inner wall of the outflow pipe 1010. Therefore, when blowing to the right, the wind can be effectively blown farther and over a larger range.

[0114] It can effectively cover the tobacco leaves on the left and right sides in the baking room 1, enabling them to receive sufficient air volume and heat, making the baking of the tobacco leaves on both sides in the baking room 1 more uniform, avoiding uneven baking of the tobacco leaves on both sides. Moreover, the continuously swinging swing piece can make the wind swing left and right periodically in the baking room 1, avoiding poor drying effect, low moisture exhaust efficiency, uneven baking, etc. caused by the formation of a wind wall on the surface of the tobacco leaves due to the long-term flow of the wind along the surface of the tobacco leaves, effectively improving the drying and moisture exhaust effects and making the baking more uniform.

[0115] In the embodiment of the present invention, the included angle β1 between the left swing piece 1050 and the outlet of the outflow pipe 1010 when rotating towards the left is the same as the included angle γ3 between the right swing piece 1056 and the outlet of the outflow pipe 1010 when rotating towards the right; the included angle β2 between the middle swing piece 1053 and the outlet of the outflow pipe 1010 when rotating towards the left is the same as the included angle γ2 between the middle swing piece 1053 and the outlet of the outflow pipe 1010 when rotating towards the right; the included angle β3 between the right swing piece 1056 and the outlet of the outflow pipe 1010 when rotating towards the left is the same as the included angle γ1 between the left swing piece 1050 and the outlet of the outflow pipe 1010 when rotating towards the right.

[0116] By adopting the above technical solution, when the wind blows to the left or to the right, the blowing distance and range are the same, and the baking ranges on the left and right sides are the same, making the baking of the tobacco leaves in the baking room 1 more uniform.

[0117] In the embodiment of the present invention, the left guiding piece 1051 and the right guiding piece 1057 are respectively inclined away from the middle guiding piece 1054, the middle swinging piece 1053 is arranged parallel to the middle guiding piece 1054, the included angle α1 between the left swinging piece 1050 and the left guiding piece 1051 is the same as the included angle α3 between the right swinging piece 1056 and the right guiding piece 1057. The connecting rod 1059 is rotatably connected to the upper ends of the left guiding piece 1051, the middle guiding piece 1054 and the right guiding piece 1057. When the left swinging piece 1050, the middle swinging piece 1053 and the right swinging piece 1056 are vertically downward, the hinge points of the connecting rod 1059 with the left guiding piece 1051, the middle guiding piece 1054 and the right guiding piece 1057 are on the same horizontal line.

[0118] By adopting the above technical solution, when the second driving device 107 drives one of the swinging pieces to rotate around the rotating shaft, the other two swinging pieces are driven to swing through the connection between the guiding piece and the connecting rod 1059. Since the included angles between the left swinging piece 1050 and the left guiding piece 1051 and between the right swinging piece 1056 and the right guiding piece 1057 are the same, when rotating around the rotating shaft, the rotation angles of the left swinging piece 1050, the middle swinging piece 1053 and the right swinging piece 1056 are all different, so that the included angles between the left swinging piece 1050, the middle swinging piece 1053 and the right swinging piece 1056 and the outlet of the outflow pipe 1010 are different, forming a gradually narrowing space between the left swinging piece 1050 and the left inner wall of the outflow pipe 1010 when rotating to the left, or forming a gradually narrowing space between the right swinging piece 1056 and the right inner wall of the outflow pipe 1010 when rotating to the right; moreover, the rotated left guiding piece 1051, middle guiding piece 1054 and right guiding piece 1057 can effectively introduce the wind between the adjacent two swinging pieces or between the inner wall of the outflow pipe 1010, making the wind guiding effect better and more uniform.

[0119] In the embodiment of the present invention, the lower end outlet of the outflow pipe 1010 is provided with a flared opening.

[0120] By adopting the above technical solution, when the wind blows to the left and right sides, the blowing angle is larger and the coverage range is wider.

[0121] In the embodiment of the present invention, the second driving device 107 includes:

[0122] The first gear 1070, the number of the first gears 1070 is the same as the number of the middle rotating shafts 1055;

[0123] The first rack 1071, the first rack 1071 is meshed with the first gear 1070;

[0124] The fixed block 1072 is provided on the outer wall of the baking chamber 1. A through hole for the first rack 1071 to pass through and slide is transversely formed in the fixed block 1072.

[0125] The frame 1073 has a hollow interior and is square in shape. Second racks 1074 and third racks 1075 are respectively provided on the upper and lower sides of the inner wall of the frame 1073. The frame 1073 is fixedly connected to the first rack 1071.

[0126] The second gear 1076 is rotatably connected to the outer wall of the baking chamber 1. The second gear 1076 is provided inside the frame 1073 and between the second rack 1074 and the third rack 1075. The second gear 1076 is separately meshed with either the second rack 1074 or the third rack 1075. The angle of the teeth on the second gear 1076 occupying the central angle is less than 180°.

[0127] The second motor is fixedly installed on the outer wall of the baking chamber 1 and is used to drive the second gear 1076 to rotate.

[0128] Wherein, one end of the middle rotating shaft 1055 passes through the baking chamber 1 and extends outwards. The first gear 1070 is connected to one end of the middle rotating shaft 1055. When the second rack 1074 is meshed with the second gear 1076, the third rack 1075 is separated from the second gear 1076. When the third rack 1075 is meshed with the second gear 1076, the second rack 1074 is separated from the second gear 1076.

[0129] By adopting the above technical solution, the second gear 1076 only rotates relative to the baking chamber 1, and the first rack 1071 and the frame 1073 only slide relative to the baking chamber 1. The second motor drives the second gear 1076 to rotate. When the second gear 1076 meshes with the second rack 1074, it does not mesh with the third rack 1075. At this time, the second gear 1076 can effectively drive the frame 1073 and the first rack 1071 to slide to the left, thereby driving the first gear 1070 and the middle rotating shaft 1055 to rotate, causing the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 to rotate towards the left simultaneously. As the second gear 1076 rotates, the second gear 1076 will disengage from the second rack 1074 and mesh with the third rack 1075. At this time, the second gear 1076 can effectively drive the frame 1073 and the first rack 1071 to slide to the right, thereby driving the first gear 1070 and the middle rotating shaft 1055 to rotate, causing the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 to rotate towards the right simultaneously. Without changing the rotation direction of the second motor, the reciprocating sliding of the first rack 1071 can be achieved, so that the left swing piece 1050, the middle swing piece 1053 and the right swing piece 1056 can swing left and right repeatedly, making the flow of air in the baking chamber 1 more uniform and effectively improving the baking effect; the angle of the teeth on the second gear 1076 occupying the central angle is less than 180°, which can effectively prevent the second gear 1076 from being stuck due to simultaneously meshing with the second rack 1074 and the third rack 1075.

[0130] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
