In some existing baking equipment, the heated air is blown directly from all sides to the items to be baked. At the same time, the baked air is directly discharged to the outside of the equipment through the air outlet. At this time, the discharged air still contains heat, and direct discharge will cause heat waste. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, the utility model provides a baking device with energy-saving and environmental protection functions, including a fan 1 and a pipeline 2, and also includes:

[0024] The heating part 3 includes a heating shell 31, an air inlet 32 ​​is provided at the top of the heating shell 31, a hot air outlet 33 is provided at one side of the heating shell 31, the hot air outlet 33 is fixedly connected to the fan 1, mounting openings 34 are provided at two opposite sides of the heating shell 31, and a partition 35 and a heater 38 are fixedly connected inside the heating shell 31;

[0025] The baking part 4 comprises a baking shell 41, a hot air inlet 42 is provided on one side of the baking shell 41, the hot air inlet 42 is fixedly connected to the fan 1, an air outlet 43 is provided on the top of the baking shell 41, a rotating shaft 46 is rotatably installed inside the baking shell 41, a wind wheel 47 and a baking rack 48 are fixedly sleeved on the outer surface of the rotating shaft 46, a mounting ring 49 is rotatably installed on the inner surface of the air outlet 43, and the top end of the rotating shaft 46 is fixedly sleeved in the mounting ring 49;

[0026] The heat exchange part 5 includes two symmetrical fixing plates 51, which are fixedly sleeved in the mounting opening 34. An air duct opening 52 is provided on the side of the fixing plate 51. An air duct pipe 53 is fixedly connected between the two fixing plates 51, and the air duct pipe 53 is communicated with the air duct opening 52.

[0027] The top of the heating shell 31 is provided with an air inlet 32, and the side thereof is provided with a hot air outlet 33, which is fixedly connected to one end of the fan 1, and the interior of the heating shell 31 is fixedly connected with a partition 35, which divides the interior of the heating shell 31 into a heat exchange chamber 36 and a heating chamber 37. After the fan 1 is turned on, air is sucked into the heat exchange chamber 36 from the outside through the air inlet 32 ​​and exchanges heat with the hot air in the heat exchange part 5 in the heat exchange chamber 36 to be preheated, and then the preheated air continues to move to the heating chamber 37. The hot air rolled by the fan 1 is sent into the baking shell 41, and the wind wheel 47 and the hot air inlet 42 are on the same horizontal line. The hot air rolled by the fan 1 will drive the wind wheel 47 to rotate, and then drive the rotating shaft 46 and the baking rack 48 to rotate. This seems to make the hot air in the baking shell 41 more fully contact with the baked objects on the baking rack 48, thereby improving the baking effect.

[0028] After the hot air leaves the air outlet 43 opened at the top of the baking shell 41, the hot air will enter the heat exchange part 5 along the pipe 2. At this time, the air entering the heat exchange cavity 36 from the air inlet 32 ​​will exchange heat with the hot air in the heat exchange part 5 and be preheated to save energy consumption.

[0029] like Figure 2 As shown, the partition 35 divides the inner cavity of the heating shell 31 into a heat exchange cavity 36 and a heating cavity 37. The heat exchange cavity 36 is located above the heating cavity 37. The partition 35 has a ventilation hole to connect the heat exchange cavity 36 and the heating cavity 37. The heater 38 is located inside the heating cavity 37.

[0030] The partition 35 is located inside the heating shell 31 and divides the inner cavity of the heating shell 31 into a heat exchange cavity 36 and a heating cavity 37. When the air enters the heating shell 31 from the air inlet 32, it first exchanges heat with the hot air flow in the heat exchange part 5 in the heat exchange cavity 36. At this time, the air will be preheated. Then, the air enters the heating cavity 37 through the vents opened on the partition 35 and is heated by the heater 38. Then, the hot air is sent into the baking part 4 by the fan 1.

[0031] like Figure 1 As shown, a trap door 44 is hinged on the outer surface of the baking shell 41 , and an observation window 45 is formed on the trap door 44 .

[0032] A trap door 44 is hinged on the outer surface of the baking shell 41 to facilitate taking out the baked items from the baking shell 41 and putting the items to be baked into it, and an observation window 45 opened on the trap door 44 allows the staff to better observe the baking results inside when the equipment is working.

[0033] like Figure 2 and Figure 4 As shown, a plurality of groups of heat dissipation fins 54 are fixedly connected to the outer surface of the air duct tube 53 , and the heat dissipation fins 54 are perpendicular to the air duct tube 53 .

[0034] A plurality of heat dissipation fins 54 are fixedly connected to the outer surface of the air duct tube 53 , and the heat dissipation fins 54 are perpendicular to the air duct tube 53 , thereby increasing the heat exchange efficiency between the air from the top to the bottom of the air duct tube 53 and the air in the air duct tube 53 .

[0035] like Figure 2 As shown, the air duct 53 and the heat dissipation fins 54 are both located inside the heat exchange cavity 36 , and are perpendicular to the air inlet 32 ​​so that the contact area between the air duct 53 and the heat dissipation fins 54 and the air flow is maximized.

[0036] The air duct tube 53 and the heat dissipation fins 54 are both located in the heat exchange chamber 36, and the air duct tube 53 and the heat dissipation fins 54 are both perpendicular to the air inlet 32. After the air enters the heat exchange chamber 36 from the air inlet 32, the air flow direction is vertical, and passes through the gap between the air duct tube 53 and the heat dissipation fins 54 and enters the heating chamber 37. When the air passes through the gap between the air duct tube 53 and the heat dissipation fins 54, it will exchange heat with the hot air in the air duct tube 53, and the heat dissipation fins 54 improve the heat dissipation efficiency of the hot air, thereby increasing the heat exchange efficiency.

[0037] like Figure 3 As shown, the hot air inlet 42 is perpendicular to the air outlet 43 , the wind wheel 47 and the hot air inlet 42 are located on the same horizontal line, and both ends of the pipe 2 are respectively connected to the air outlet 43 and the fixing plate 51 so that the air outlet 43 and the fixing plate 51 are connected.

[0038] The wind wheel 47 is on the same horizontal line as the hot air inlet 42. When the fan 1 sends the hot air flow from the hot air inlet 42 into the baking shell 41, the hot air flow will drive the wind wheel 47 to rotate and drive the rotating shaft 46 and the baking rack 48 to rotate, so that the contact between the baked items and the hot air flow is more uniform and sufficient, thereby enhancing the baking effect.

[0039] The working principle of this utility model:

[0040] When using the present device, first open the trap door 44, put the items to be baked on the baking rack 48, then close the trap door 44, turn on the fan 1, and suck air from the air inlet 32. Then the air is preheated through the heat exchange part 5, and then the preheated air enters the heating chamber 37 and is heated by the heater 38. Then the fan 1 will transport the heated hot air to the baking shell 41. At this time, the hot air flow formed by the hot air will blow the wind wheel 47 to rotate, and the rotation of the wind wheel 47 will drive the rotating shaft 46 and the baking rack 48 to rotate, so that the items to be baked on the baking rack 48 can be fully contacted with the preheated air flow, thereby improving the baking efficiency and baking effect. Then the hot air flow will enter the heat exchange part 5 through the pipe 2 and exchange heat with the air subsequently sucked into the heat exchange chamber 36 to save energy consumption, and finally blown out from the other end of the heat exchange part 5.

[0041] The air duct pipe 53 and the heat dissipation fins 54 in the heat exchange part 5 are both perpendicular to the air inlet 32. After the air is drawn into the heat exchange chamber 36 from the outside by the power of the fan 1, it will be perpendicular to the heat exchange part 5. At this time, the airflow will pass through the gap between the air duct pipe 53 and the heat dissipation fins 54 and enter the heating chamber 37. The heat dissipation fins 54 can improve the heat release efficiency of the hot air flow in the air duct pipe 53, reduce heat loss, and improve the utilization efficiency of waste heat.

[0042] The trap door 44 hinged on the outer surface of the baking shell 41 can more conveniently and quickly replace the items in the baking shell 41. At the same time, the observation window 45 opened on the trap door 44 can be used to observe the baking effect of the baked items during the baking process of the equipment. When the baked items do not meet the standards, the equipment can be shut down to reduce losses.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
