[0030] Example 1

[0031] The ground window of this utility model includes a ground window frame 1, ground window blades 2, and an isolation plate 3 for isolating pests. A first ventilation opening 4 is provided on the ground window frame 1. The ground window blades 2 are movably disposed on the ground window frame 1 to open and close the first ventilation opening 4. A second ventilation opening 5 is provided on the isolation plate 3, and the second ventilation opening 5 connects the first ventilation opening 4 to the side of the isolation plate 3 away from the first ventilation opening 4.

[0032] This application uses isolation plate 3 to isolate pests, thus achieving the insect-proof function of the floor window. Specifically, as... Figure 1 , Figure 6 , Figure 7 and Figure 9 As shown, the ground window of this application includes a ground window frame 1, ground window blades 2, and an isolation plate 3. The ground window frame 1 is rectangular and is used to install the ground window blades 2 and the isolation plate 3. The ground window blades 2 serve as the switch for ground window ventilation, and the isolation plate 3 is used to isolate pests. The isolation plate 3 and the ground window frame 1 can be welded together. Furthermore, a first ventilation opening 4 is provided on the ground window frame 1. The ground window blades 2 are movably connected to the ground window frame 1. The opening and closing of the first ventilation opening 4 is achieved through the movable connection of the ground window blades 2, thereby opening and closing the ground window. When the ground window is open, the first ventilation opening 4 enables ventilation of the fermentation chamber, thus achieving dehumidification and exhaust of the fermentation chamber. When the ground window is closed, the first ventilation opening 4 enables heat preservation of the fermentation chamber. Even further, a second ventilation opening 5 is provided on the isolation plate 3. The size of the second ventilation opening 5 is designed according to the size of the pests. Preferably, the size of the second ventilation opening 5 is smaller than the size of the pests, so as to facilitate the isolation of pests by the isolation plate 3. Due to the presence of the second vent 5, the isolation plate 3 not only prevents pests from entering the fermentation chamber through the second vent 5, but also enables ventilation of the fermentation chamber. Therefore, the floor window of this application can simultaneously provide ventilation and pest control, thereby improving the quality of baijiu brewing and ensuring food safety. Since rice straw is one of the main auxiliary materials used in the fermentation of daqu (a type of starter culture) in the fermentation chamber, the isolation plate 3 also prevents rice straw from falling into the factory passageway through the floor window, ensuring the cleanliness of the factory passageway. The isolation plate 3 is rectangular, and the second vent 5 on the isolation plate 3 is cylindrical. The cylindrical second vent 5 are arranged in a rectangular array on the isolation plate 3, such as... Figure 9As shown. The floor window of this application is made of aluminum alloy, a material that combines high strength and lightweight properties, offering excellent impact resistance while reducing the burden on the building structure and facilitating installation. Aluminum alloy is corrosion-resistant and durable; its surface oxide film resists erosion from humid and acidic / alkaline environments, resulting in a service life of 20-30 years and low maintenance costs. Furthermore, compared to thermally broken aluminum or stainless steel, aluminum alloy is more cost-effective, making it more suitable for budget-constrained applications. During factory production, the blank rolling mill is prone to collisions with walls, and the floor window is easily deformed by impact. Aluminum alloy floor windows exhibit significant hardness upon impact, maintaining their shape and resisting damage. The use of aluminum alloy also provides excellent thermal insulation, enhancing the heat preservation effect. During the fermentation process of Daqu (a type of koji) in the fermentation chamber, a large amount of heat is generated, with the temperature inside the chamber reaching over 40℃. As a result, the Daqu evaporates moisture, and the concentrations of O2 and CO2 change. Therefore, operators need to monitor the Daqu and the environment inside the fermentation chamber and perform operations such as opening and closing the floor windows, turning the Daqu, and burning it. Opening and closing the floor windows is used to regulate the temperature and humidity inside the fermentation chamber, as well as for dehumidification, to control the environmental parameters during Daqu fermentation to achieve the optimal environment required for fermentation. The high temperature and humidity environment during Daqu fermentation is detrimental to the health of the operators. Meanwhile, dehumidification and exhaust are essential steps in Daqu production. To fully utilize natural ventilation to solve the indoor environment and temperature problems, reduce equipment operating energy consumption, and achieve energy conservation and emission reduction, this application uses floor windows as a major component of the fermentation chamber ventilation system, serving as a "gateway" for air exchange between the inside and outside of the fermentation chamber.

[0033] In one embodiment, the floor window blades 2 are rotatably mounted on the floor window frame 1, and any two floor window blades 2 are connected by a connecting rod 6, and any two floor window blades 2 are arranged in parallel.

[0034] The floor-to-ceiling window in this application uses louvered blinds. Specifically, such as... Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the ground window of this application includes several ground window blades 2, which are rotatably mounted on the ground window frame 1. These blades rotate synchronously via a connecting rod 6 and are arranged in parallel, thus forming a louvered window with the frame 1. Preferably, three blades are provided. When the louvered blades 2 open synchronously, ventilation of the fermentation chamber is achieved; when they close synchronously, insulation of the fermentation chamber is achieved. Therefore, the ground window of this application can simultaneously provide ventilation and insulation for the fermentation chamber (especially insulation in winter, which can improve fermentation efficiency), remove waste gas generated during fermentation, optimize air quality inside the chamber, protect the health of employees, improve fermentation quality, and thus improve the quality of baijiu brewing, while also ensuring food safety. When the starter culture is introduced into the fermentation chamber, the bottom window blades 2 need to be closed, effectively sealing the fermentation chamber to maintain warmth and humidity, creating suitable temperature conditions for microbial reproduction. In the later stages of fermentation, the growth and reproduction of microorganisms produce a large amount of CO2 and water vapor, requiring the bottom window blades 2 to be opened for ventilation, moisture removal, and exhaust of waste gas. The use of this adjustable bottom window improves the internal environment of the fermentation chamber, balances the internal and external gas circulation, promotes better microbial reproduction, improves the environment while ensuring the quality of the starter culture, and further promotes the energy-saving and efficient production of starter culture.

[0035] In one embodiment, the ground window blade 2 is provided with a first sealing part 7 and a second sealing part 8, and the first sealing part 7 of any ground window blade 2 is sealed with the second sealing part 8 of the adjacent ground window blade 2.

[0036] This application improves the sealing performance between the floor window blades 2 by using the first sealing part 7 and the second sealing part 8. Specifically, when the floor window blades 2 open simultaneously, the first sealing part 7 and the second sealing part 8 separate, forming an air duct between two adjacent floor window blades 2, such as... Figure 6 As shown, the air duct connects the outside to the first ventilation opening 4 of the ground window, and the first ventilation opening 4 is connected to the inside of the fermentation chamber through the second ventilation opening 5 to achieve the ventilation function of the fermentation chamber; as shown Figure 1 and Figure 2 As shown, when the window blades 2 close simultaneously, the first sealing part 7 and the second sealing part 8 come into contact and seal, and the first sealing part 7 and the second sealing part 8 seal the first vent 4, disconnecting the second vent 5 from the outside air duct, thereby sealing the fermentation chamber and realizing the heat preservation function of the fermentation chamber.

[0037] In one embodiment, the first sealing part 7 includes a plurality of sealing teeth 9, and the second sealing part 8 includes a plurality of sealing grooves 10, with the sealing teeth 9 inserted into the sealing grooves 10.

[0038] This application achieves sealing of the first vent 4 through the cooperation of the sealing teeth 9 and the sealing groove 10. Specifically, as shown... Figure 3As shown, the first sealing part 7 on the ground window blade 2 includes several sealing teeth 9, and the second sealing part 8 on the ground window blade 2 includes several sealing grooves 10. When the ground window blades 2 are closed simultaneously, the sealing teeth 9 are inserted into the sealing grooves 10. The cooperation between the sealing teeth 9 and the sealing grooves 10 seals the first vent 4, thereby disconnecting the second vent 5 from the outside air duct, thus sealing the fermentation chamber and achieving the heat preservation function of the fermentation chamber. Furthermore, multiple sealing teeth 9 and sealing grooves 10 are provided, which can improve the sealing ability between the first sealing part 7 and the second sealing part 8, thereby improving the heat preservation effect of the fermentation chamber. Among them, the groove opening size of the sealing groove 10 is larger than its bottom size, making the groove opening of the sealing groove 10 funnel-shaped, which facilitates the insertion of the sealing teeth 9 into the sealing groove 10. In addition, the ends of the sealing teeth 9 are chamfered or rounded, which further facilitates the insertion of the ends of the sealing teeth 9 into the sealing groove 10.

[0039] In one embodiment, the second sealing part 8 further includes a sealing rubber 11, which is disposed in the sealing groove 10, and the sealing teeth 9 are in contact with the sealing rubber 11.

[0040] This application improves the sealing capability between the first sealing part 7 and the second sealing part 8 by using sealing rubber 11. Specifically, as shown... Figure 4 As shown, the second sealing part 8 includes a sealing groove 10 and a sealing rubber 11. The sealing rubber 11 is disposed at the bottom of the sealing groove 10. When the sealing tooth 9 is inserted into the sealing groove 10, the end of the sealing tooth 9 contacts the sealing rubber 11 in the sealing groove 10, thereby improving the sealing ability between two adjacent floor window blades 2 through the sealing rubber 11. Further, as... Figure 5 As shown, the sealing rubber 11 is U-shaped, forming a U-shaped groove. When the sealing tooth 9 is inserted into the sealing groove 10, the sealing tooth 9 is inserted into the U-shaped groove on the sealing rubber 11. At this time, there is a contact force between the sealing tooth 9 and the sealing rubber 11 in a direction perpendicular to the sealing tooth 9, which further improves the fit between the first sealing part 7 and the second sealing part 8, improves the sealing ability between the sealing tooth 9 and the sealing rubber 11, and thus improves the heat preservation ability of the fermentation chamber, which meets the standards of the Daqu fermentation process and improves the effect of Daqu fermentation.

[0041] In one embodiment, a first hinge shaft 12 is provided on the floor window blade 2, and a first hinge hole 13 is provided on the floor window frame 1, with the first hinge shaft 12 hinged to the first hinge hole 13.

[0042] This application achieves the rotation function of the floor window blade 2 through the cooperation of the first hinge shaft 12 and the first hinge hole 13. For example... Figure 8 and Figure 9As shown, a first hinge shaft 12 is provided at the center of both sides of the floor window blade 2. First hinge holes 13 are provided on the left and right side walls of the first vent 4 on the floor window frame 1. When the floor window blade 2 is installed on the floor window frame 1, the first hinge shaft 12 on one side of the floor window blade 2 is inserted into the first hinge hole 13 on one side of the floor window frame 1, and the first hinge shaft 12 on the other side of the floor window blade 2 is inserted into the first hinge hole 13 on the other side of the floor window frame 1. The hinged engagement between the first hinge shaft 12 and the first hinge hole 13 enables the floor window blade 2 to rotate on the floor window frame 1, thereby opening and closing the first vent 4 through the synchronous rotation of the floor window blade 2. Furthermore, the first hinge shaft 12 and the first hinge hole 13 are interference-fitted so that when the user opens the floor window blade 2, the floor window blade 2 is not easily rotated on the floor window frame 1 under the influence of airflow or other forces, thus ensuring the angle of the floor window blade 2 when opened on the floor window frame 1. The axes of the first hinge shaft 12 and the first hinge hole 13 are arranged in the horizontal direction.

[0043] In one embodiment, a second hinge shaft 14 is provided on the floor window blade 2, and a second hinge hole 15 is provided on the connecting rod 6. The second hinge shaft 14 is hinged to the second hinge hole 15.

[0044] This application achieves synchronous rotation of the floor window blades 2 via connecting rod 6. Specifically, as shown... Figure 8 and Figure 9As shown, the ground window of this application includes a connecting rod 6, on which a second hinge hole 15 is provided. A second hinge shaft 14 is provided on the ground window blade 2. The second hinge shaft 14 of the ground window blade 2 is inserted into the second hinge hole 15 on the connecting rod 6. The rotatable movement of the ground window blade 2 relative to the connecting rod 6 is achieved through the hinged engagement of the second hinge shaft 14 and the second hinge hole 15. For example, each ground window blade 2 has a second hinge shaft 14 on both its left and right sides, and the two second hinge shafts 14 of the same ground window blade 2 are coaxially arranged. Two connecting rods 6 are provided, each with three second hinge holes 15. The two connecting rods 6 are respectively located on the left and right sides of the ground window blade 2. The second hinge shaft 14 located on the left side of the ground window blade 2 is inserted into the second hinge hole 15 on the connecting rod 6 located on the left side of the ground window blade 2, and the second hinge shaft 14 located on the right side of the ground window blade 2 is inserted into the second hinge hole 15 on the connecting rod 6 located on the right side of the ground window blade 2. Furthermore, the distance between any two adjacent first hinge shafts 12 of the floor window blades 2 is the first distance, and the distance between any two adjacent second hinge holes 15 on the connecting rod 6 is the second distance. The first distance is equal to the second distance, and the first hinge shaft 12 and the second hinge shaft 14 are arranged parallel to each other to facilitate the parallel arrangement and synchronous rotation of the floor window blades 2. The hinge shafts (first hinge shaft 12 and second hinge shaft 14) and the hinge holes (first hinge hole 13 and second hinge hole 15) are made of highly wear-resistant materials to extend their service life. Regular lubrication reduces friction, and the dimensions of the connecting rod 6, hinge shafts, and hinge holes are designed according to the actual scenario to avoid deformation or breakage caused by overload.

[0045] In one embodiment, a handle 16 is provided on the floor window blade 2, and the handle 16 and the second hinge shaft 14 are respectively provided on both sides of the first hinge shaft 12 in a direction perpendicular to the first hinge shaft 12.

[0046] This application uses handle 16 to drive the synchronous rotation of several floor window blades 2. For example... Figure 8 and Figure 9 As shown, this application only requires a handle 16 to be provided on one of the floor window blades 2. Furthermore, with... Figure 9Taking the direction shown as an example, the handle 16, the first hinge shaft 12 and the second hinge shaft 14 on the ground window blade 2 of this application are arranged in sequence. That is, the handle 16 and the second hinge shaft 14 are respectively arranged on the front and rear sides of the first hinge shaft 12. The handle 16 is located on the side away from the fermentation chamber, and the second hinge shaft 14 is located on the side close to the fermentation chamber. For example, the three floor window blades 2 are arranged from top to bottom as a first blade, a second blade, and a third blade. A handle 16 is set on the second blade. When the floor window blade 2 needs to be opened by using the handle 16, the user pulls the handle 16, which causes the second blade to rotate clockwise around the first hinge axis 12 on the second blade. At the same time, the second hinge axis 14 on the second blade drives the connecting rod 6 to move upward through the second hinge hole 15 in the middle of the connecting rod 6. The second hinge hole 15 at the top of the connecting rod 6 causes the second hinge axis 14 on the first blade to rotate clockwise around the first hinge axis 12 on the first blade. The second hinge hole 15 at the bottom of the connecting rod 6 causes the second hinge axis 14 on the third blade to rotate clockwise around the first hinge axis 12 on the third blade. Therefore, the three floor window blades 2 rotate clockwise synchronously to open the floor window.

[0047] In one embodiment, the floor window frame 1 is provided with scale lines 17, and the floor window blades 2 cooperate with the scale lines 17 to adjust the opening angle of the floor window blades 2.

[0048] This application indicates the opening angle of the floor window slats 2 using scale line 17. Specifically, as shown... Figure 6 As shown, scale lines 17 are set on the left and right sides of the floor window frame 1, and the reference center of scale lines 17 is set on the axis of the first hinge hole 13 of the middle floor window blade 2. When the user pulls the floor window blade 2 with the handle 16, the opening angle of the floor window blade 2 is adjusted by the cooperation between the middle floor window blade 2 and the scale lines 17, so as to set the floor window blade 2 at the required angle and facilitate the adjustment of parameters such as air volume.

A second ventilation opening 5 is provided on the isolation plate 3, which connects the first ventilation opening 4 to the side of the isolation plate 3 away from the first ventilation opening 4.

[0051] Specifically, such as Figure 10As shown, the fermentation chamber is provided with mounting holes 20, and the floor window frame 1 is installed in the mounting holes 20. A connector 19 is provided on the floor window frame 1, and the connector 19 is connected to the chamber wall 18 of the fermentation chamber. When the floor window blades 2 are open, an air duct is formed between two adjacent floor window blades 2, connecting the first ventilation opening 4 to the outside. The second ventilation opening 5 on the isolation plate 3 connects the first ventilation opening 4 to the fermentation chamber, thus achieving ventilation between the fermentation chamber and the outside, and enabling the dehumidification and exhaust of the fermentation chamber. When the floor window blades 2 are closed, the floor window blades 2 seal the first ventilation opening 4 and disconnect the air duct between the second ventilation opening 5 and the outside, thus sealing the fermentation chamber and achieving its heat preservation function. The isolation plate 3 prevents pests from entering the fermentation chamber through the second ventilation opening; the second ventilation opening 5 of the isolation plate 3 also enables ventilation of the fermentation chamber. Therefore, the floor window of this application combines ventilation and insect prevention, improving the quality of baijiu brewing.
