[0046] Continuing to refer to Figure 2 , the air outlet 4 can include a plurality of through holes arranged in an array from top to bottom, and of course, can also be other common air outlet forms, such as a slit-shaped air outlet or an irregular opening structure; similarly, the return air inlet 3 can include a plurality of through holes arranged in an array from top to bottom, and of course, can also be other common return air inlet forms, such as a slit-shaped return air inlet or an irregular opening structure.

[0047] Specifically, by setting the air outlet 4 to a form including a plurality of through holes arranged in an array from top to bottom, the coverage area of the air outlet 4 can be increased, and the ventilation efficiency can be improved; similarly, by setting the return air inlet 3 to a form including a plurality of through holes arranged in an array from top to bottom, the coverage area of the return air inlet 3 can be increased, and the ventilation efficiency can be improved.

[0048] Continuing to refer to Figure 1 and Figure 2 , the inner container 2 and the box body are provided with an atomizer 5 and a heating element 6, the moisture generated by the atomizer 5 forms hot and humid air under the action of the heating element 6, wherein in the embodiment, the fermentation box refers to a device that allows food materials to be fully fermented and expanded under the action of a certain temperature and humidity, that is, hot and humid air, to realize fermented food materials. The heating element 6 can be an air heating pipe, and of course, the heating element 6 can also be selected from other types of electric heating rods, etc., which are not specifically limited here.

[0049] Continuing to refer to Figure 1 and Figure 2 , the drainage element 7 is close to the air outlet 4, the hot and humid air enters the inner container 2 from the air outlet 4 under the driving of the drainage element 7, the hot and humid air in the inner container 2 flows back to the space between the box body 1 and the inner container 2 from the return air inlet 3, and then enters the inner container 2 from the air outlet 4 again under the driving of the drainage element 7 to form a cycle, and the hot and humid air entering the inner container 2 forms a hot and humid air circulation in the front and back directions in the inner container 2 for fermenting food materials. Wherein, the drainage element 7 can be a cross-flow fan, and of course, the drainage element 7 can also be selected from other types of fans or motors, etc., which are not specifically limited here.

[0050] The working principle of the fermentation box provided in the embodiment of the utility model is that the moisture generated by the atomizer 5 in the space between the box body 1 and the inner container 2 forms hot and humid air under the action of the heating element 6, the hot and humid air enters the inner container 2 from the air outlet 4 under the drive of the drainage element 7, the hot and humid air in the inner container 2 forms a hot and humid air circulation in the front-rear direction in the inner container 2 for fermenting food materials, the hot and humid air in the inner container 2 flows back to the space between the box body 1 and the inner container 2 from the air return port 3, and then enters the inner container 2 from the air outlet 4 under the drive of the drainage element 7 again to form a circulation, thereby ensuring constant temperature and humidity in the inner container 2.

[0051] As can be seen from the above, the fermentation box provided in the embodiment of the utility model comprises a box body 1 and a drainage element 7, the box body 1 is internally provided with an inner container 2, one side of the inner container 2 is respectively provided with an air return port 3 and an air outlet 4 in the front-rear direction, the inner container 2 and the box body are provided with an atomizer 5 and a heating element 6, the moisture generated by the atomizer 5 forms hot and humid air under the action of the heating element 6; the drainage element 7 is close to the air outlet 4, the hot and humid air enters the inner container 2 from the air outlet 4 under the drive of the drainage element 7, the hot and humid air in the inner container 2 flows back to the space between the box body 1 and the inner container 2 from the air return port 3, and the hot and humid air forms a hot and humid air circulation in the front-rear direction in the inner container 2 for fermenting food materials. Therefore, by respectively arranging the air return port 3 and the air outlet 4 on one side of the inner container 2 in the front-rear direction and arranging the drainage element 7 close to the air outlet 4, the hot and humid air can enter the inner container 2 from the air outlet 4 under the drive of the drainage element 7, the hot and humid air in the inner container 2 flows back to the space between the box body 1 and the inner container 2 from the air return port 3, the hot and humid air can mainly circulate in the front-rear direction of the inner container, and the air duct structure is arranged in the side space between the inner container 2 and the box body 1, without occupying the inner container space, thereby improving the utilization rate of the inner container space.

[0052] Continuing to refer to Figure 1 , the height of the inner container 2 is less than the depth of the inner container 2, that is, the inner container 2 is a flat structure, the inner space of the flat inner container 2 is relatively short in height, the air flow distance in the height direction is short, the hot and humid air circulation in the front-rear direction is formed in the inner container 2, and the structure for generating hot and humid air is arranged in the side space between the inner container 2 and the box body 1, without occupying the inner container 2 space in the height direction, which is beneficial to the uniform distribution of temperature and humidity in the flat inner container 2, and is beneficial to improving the fermentation quality.

[0053] In the height direction, the side wall of the inner container 2 is provided with two or more groups of hangers 8, which are used to support fermentation trays 9, and the fermentation trays 9 divide the inner container 2 into different fermentation spaces. In this way, the heat and humidity circulation structure of the present embodiment can realize the simultaneous fermentation of two or more food materials in the flat inner container space, and the efficiency is higher. Taking two groups of hangers 8 as an example, the fermentation trays 9 divide the inner container 2 into upper, middle and lower fermentation spaces, and two fermentation trays 9 can be fermented at the same time, thereby improving the production efficiency. Specifically, the fermentation trays 9 can be baking trays for baking food materials, and because the depth of the inner container 2 is large, two fermentation trays 9 can be placed on the same group of hangers 8 in front and back, so that four food materials can be fermented at the same time.

[0054] Continuing to refer to Figure 1 , the hangers 8 are provided with ventilation holes 10, and part of the heat and humidity circulates through the ventilation holes 10 in different fermentation spaces. Among them, the ventilation holes 10 can include a plurality of through holes distributed along the length direction of the hangers 8. Of course, the ventilation holes 10 can also adopt a through hole structure that is designed in part of the hangers 8 or along the length direction of the hangers 8. In the present embodiment, after the fermentation trays are placed in the hangers 8, there will be a gap between the front and back of the fermentation trays and the front end and the rear wall of the inner container, and part of the heat and humidity can also circulate through the gap between the front and back in the upper and lower different fermentation spaces.

[0055] Specifically, by setting the ventilation holes 10 to include a plurality of through holes distributed along the length direction of the hangers 8, the ventilation in the front and back direction is uniform, and the heat and humidity distribution uniformity of the inner container 2 in the front and back direction is improved.

[0056] The adjacent two fermentation spaces can be ventilated and temperature-coupled through the ventilation holes 10, so that the temperature and humidity of each fermentation space are the same, and the constant temperature and humidity required for fermentation can be achieved, further making the temperature and humidity in the entire inner container 2 uniform and consistent during fermentation, and ensuring the fermentation effect.

[0057] Continuing to refer to Figure 1 and Figure 2 , the outer side edges of the hangers 8 are provided with a beat edge structure 11, and the fermentation trays 9 are placed on the beat edge structure 11, which can not only improve the strength of the hangers 8, but also ensure that the fermentation trays 9 will not be cut when pulled out.

[0058] In addition, the end of the hanger 8 is provided with an arc transition structure, and the curvature of the arc transition structure is set according to the actual end structure of the hanger 8, which is not limited here. By setting the arc transition structure, the food materials placed on the fermentation trays 9 can be prevented from being scratched or damaged, and at the same time, the arc transition structure can reduce the resistance of air flow, which is helpful for the air circulation in the inner container 2, so that the temperature and humidity in the entire inner container 2 are uniform and consistent.

[0059] Continuing to refer to Figure 2The air outlet 4 is arranged at the lower part of the side wall of the inner container 2, and the air return port 3 is arranged at the lower part of the side wall of the inner container 2. Since the natural flow direction of the hot and humid air is from bottom to top, the hot and humid air below the inner container 2 is small, especially for the fermentation tank without an additional heating element, the heat of the fermented food mainly depends on the hot and humid air, therefore, the air outlet 4 and the air return port 3 are arranged at the lower part of the side wall of the inner container 2, so as to avoid the insufficient fermentation of the food below caused by the insufficient hot and humid air below.

[0060] Continuing to refer to Figure 2 The air outlet 4 is away from the door of the fermentation tank, and the air return port 3 is close to the door, so that the hot and humid air from the air outlet 4 can flow to the vicinity of the door as much as possible along the front-rear direction, thereby avoiding the insufficient fermentation of the food close to the door.

[0061] Continuing to refer to Figure 1 In the height direction, the end of the air outlet 4 is away from the hanger 8, and the end of the air return port 3 is away from the hanger 8. This is because, if the end of the air outlet 4 and the end of the air return port 3 are close to the hanger 8, the air flowing through the air outlet 4 and the air return port 3 will directly blow on the food, which will dry the surface of the fermented food and reduce the fermentation effect. Therefore, the end of the air outlet 4 and the end of the air return port 3 are away from the hanger 8, so as to avoid the direct blowing of the air on the food and improve the fermentation effect.

[0062] Continuing to refer to Figure 1 The bottom of the inner container 2 is provided with a drain pipe 12 extending to the outside of the tank body 1, through which the sewage such as condensate water generated during fermentation can be discharged outside the tank, without the need to disassemble the machine, and the operation is convenient.

[0063] The hanger 8 is inclined towards the center of the inner container 2. During the fermentation process of the food, part of the hot and humid air may remain at the hanger 8. If the water formed by the remaining hot and humid air continues to remain on the hanger 8, the user experience will be poor. Therefore, the hanger 8 is designed to be inclined towards the center of the inner container 2, so as to guide the water on the hanger 8 to the bottom of the inner container 2 and discharge it uniformly through the drain pipe 12. In addition, the inclined hanger 8 can reduce the contact area with the fermentation tray, thereby reducing the abrasion of the fermentation tray when it is pushed and pulled.

[0064] Figure 3 Another structural schematic view of the fermentation tank provided by the embodiment of the present application is shown. Referring to Figure 3 The fermentation tank provided by the embodiment of the present application further comprises an air duct tank 13 and an outer water tank 14.

[0065] In the flow direction of the hot and humid air, the air duct tank 13 is sequentially provided with a heating element 6, an inner water tank 15 and a drainage element 7. The inner water tank 15 is provided with an atomizer 5 and a water level switch 16. The water in the inner water tank 15 forms humid air under the action of the atomizer 5, and the water level switch 16 is used to detect the water amount in the inner water tank 15. Figure 3The flow direction of the hot and humid air in the humidifier is from left to right.

[0066] Since the heating element 6, the inner water tank 15 and the flow guide element 7 are all arranged in the air duct box 8, the heating element 6 can cyclically heat the humid air generated by the atomizer 5 in the air duct box 8, the heating is more sufficient, and then the heated hot and humid air flows to the inner container 2 through the flow guide of the flow guide element 7.

[0067] Continuing to refer to Figure 3 , the outer water tank 14 is arranged at the front side of the air duct box 13, the outer water tank 14 is connected with the inner water tank 15 through the water supplement pipeline, and the water supplement pipeline is provided with the water pump 17. That is, the outer water tank 14 is arranged outside the air duct box 13, and the inner water tank 15 is arranged in the air duct box 13.

[0068] By arranging the heating element 6, the inner water tank 15 and the flow guide element 7 in the air duct box 13 in sequence along the flow direction of the hot and humid air, the space occupied by the air duct box 13 in the width direction can be reduced. In addition, by arranging the outer water tank 14 at the front side of the air duct box 13, the space occupied by the outer water tank 14 and the air duct box 13 in the width direction can be reduced, and especially for the long and flat fermentation tank, the outer water tank 14 and the air duct box are more suitable for the spare space of the fermentation tank, and the difficulty of the whole machine design of the fermentation tank is avoided.

[0069] When the water level switch 16 detects that the water in the inner water tank 15 is lower than the set value, it indicates that the inner water tank 15 is short of water, at this time, the water pump 17 is actuated, and the water in the outer water tank 14 enters the inner water tank 15 through the water supplement pipeline to supplement the water in the inner water tank 15. No manual water supplement is required, automatic water supplement is realized, the problem that the water level of the fermentation tank cannot reach the range of the atomizer by manual water addition is solved, and the normal fermentation effect of the fermentation tank is ensured.

[0070] Continuing to refer to Figure 3 , the air duct box 13 is also provided with a temperature and humidity sensor 18. When the temperature and humidity sensor 18 detects that the temperature of the hot and humid air in the air duct box 13 is lower than the preset temperature value, the heating time of the heating element 6 is increased. The preset temperature value can be a temperature value set by the user or can be set according to experience, which is not limited herein.
