[0002] Fermentation refers to the process by which microorganisms, under aerobic or anaerobic conditions, produce the microbial cells themselves, or their direct or secondary metabolites. Fermented foods are a class of foods that humans ingeniously process using beneficial microorganisms, possessing unique flavors and enriching our diets. Examples include yogurt, cheese, fermented rice wine, pickles, soy sauce, vinegar, fermented black beans, fermented bean curd, rice wine, beer, wine, kombucha, and natto. The production of fermented foods relies on fermentation equipment. Currently, most household fermentation boxes on the market have a lid on top to seal the sampling port. During fermentation, a large amount of water droplets condense on the lid, which can fall onto the fermented food, thus affecting the fermentation process. Utility Model Content
[0003] To address the shortcomings of the existing technology, this utility model provides a household fermentation box to solve the problem that a large amount of water droplets condense on the lid during the fermentation process, and these water droplets fall onto the fermented food, thus affecting the fermentation process.
[0004] This utility model is achieved using the following technical solution:
[0005] A household fermentation box includes a fermentation box body with a fermentation chamber. The fermentation chamber has a top opening, and the top opening is equipped with a cover plate. The cover plate includes an outer cover plate and an inner cover plate. The inner cover plate and the outer cover plate are arranged in upper and lower layers with a cavity between them. The outer cover plate has an exhaust hole communicating with the cavity and an exhaust mechanism for controlling exhaust. The inner surface of the inner cover plate has a guide surface, which is inclined downward and outward from the middle of the inner cover plate towards the edge of the inner cover plate.
[0006] Furthermore, the inner cover plate includes a top wall and a side wall. The top wall includes a horizontal top surface. The left and right sides of the horizontal top surface are respectively provided with inclined surfaces extending towards the side wall. The inclined surfaces are arranged outward and downward, and the inclined surfaces form the flow guiding surface. The side wall extends downward and is connected to the inclined surfaces.
[0007] Furthermore, the inner cover plate is integrally stretched and formed.
[0008] Furthermore, the upper surface of the outer cover plate has two downwardly recessed grooves in the middle and two corresponding protrusions on the lower surface of the outer cover plate, and a handle protrusion is formed between the two grooves on the upper surface of the outer cover plate.
[0009] Furthermore, the inner cover plate has a connecting hole corresponding to the position of the protrusion, the shape of the connecting hole matches the shape of the protrusion, the protrusion of the outer cover plate passes through the connecting hole of the inner cover plate, and the outer diameter of the protrusion is interference-fitted with the inner diameter of the connecting hole.
[0010] Furthermore, the exhaust mechanism includes an exhaust cover that is rotatably connected to the outer cover plate and cooperates with the exhaust port to block it.
[0011] Furthermore, it also includes a control component for controlling the rotation and opening / closing of the exhaust cover.

[0027] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.
[0028] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.
[0029] like Figure 1-9As shown, this utility model provides a household fermentation box, including a fermentation box body 20 with a fermentation chamber 21. The fermentation chamber 21 has a top opening, and a cover plate 10 is disposed on the top opening. The cover plate 10 includes an outer cover plate 11 and an inner cover plate 12. The inner cover plate 12 and the outer cover plate 11 are arranged in upper and lower layers and a cavity 13 is formed between them. The outer cover plate 11 has an exhaust hole 114 communicating with the cavity 13 and an exhaust mechanism for controlling exhaust. A guide surface 121 is formed on the inner surface of the inner cover plate 12. The guide surface 121 is inclined downward and outward from the middle of the inner cover plate 12 toward the edge of the inner cover plate 12.
[0030] In this embodiment, water droplets will condense on the inner cover plate 12 during fermentation. If these droplets are not drained in time, they will fall onto the fermented material, affecting the fermentation process. Therefore, by providing a guide surface 121 on the inner surface of the inner cover plate 12, and by setting the guide surface 121 downward and outward, the water droplets condensed on the upper surface of the inner cover plate 12 can flow down along the guide surface 121 to the edge of the inner cover plate 12, that is, the water droplets flow down from the side of the fermentation chamber 21. This prevents water droplets from dripping from the middle of the inner cover plate 12, thus avoiding affecting the fermentation process. At the same time, the design of the guide surface 121 can accelerate the flow of condensed water, further effectively preventing water from accumulating on the inner cover plate 12. This fermentation chamber can ferment fermented foods such as yogurt, rice wine, wine, kombucha, and natto. Depending on the fermentation strains used, the fermentation process can be aerobic fermentation, anaerobic fermentation, or a combination of aerobic and anaerobic fermentation. In the aerobic fermentation process, not only is it necessary to introduce air, but it is also necessary to expel the gases produced during fermentation in a timely manner. The outer cover plate 11 is equipped with an exhaust hole 114 and an exhaust mechanism for controlling the exhaust, so that the waste gas generated during the fermentation process can be discharged in time to avoid affecting the fermentation process.
[0031] In a preferred embodiment, the inner cover plate 12 includes a top wall and a side wall 122. The top wall includes a horizontal top surface 123. The left and right sides of the horizontal top surface 123 are respectively provided with inclined surfaces extending toward the side wall 122. The inclined surfaces are arranged outward and downward, and the inclined surfaces form the flow guiding surface 121. The side wall 122 extends downward and is connected to the inclined surfaces.
[0032] In this embodiment, the horizontal top surface 123 is set so that the top of the inner cover plate 12 fits against the inner surface of the outer cover plate 11. The inclined surface is set outward and downward, so that the inner cover plate 12 forms a structure that is high in the middle and low around the edges. As a result, water droplets condensed on the inner cover plate 12 can quickly flow down the inclined surface to the edge of the inner cover plate 12 and flow down along the side wall 122, thereby more efficiently preventing water droplets from condensing on the inner cover plate 12.
[0033] As a preferred embodiment, the inner cover plate 12 is integrally stretched and formed. This facilitates manufacturing and processing while saving costs.
[0034] In a preferred embodiment, the upper surface of the outer cover plate 11 is provided with two downwardly recessed grooves 111 and two corresponding protrusions 112 are formed on the lower surface of the outer cover plate 11. A handle protrusion 113 is formed between the two grooves 111 on the upper surface of the outer cover plate 11.
[0035] In this embodiment, the groove 111 and the handle protrusion 113 constitute the handle structure of the outer cover plate 11. By gripping the handle protrusion 113, the cover plate 10 of the fermentation box body 20 can be opened. In addition, the groove 111 and the outer cover plate 11 are integrally formed, which facilitates manufacturing and processing.
[0036] In a preferred embodiment, the inner cover plate 12 is provided with a connecting hole 124 corresponding to the position of the protrusion 112. The shape of the connecting hole 124 matches the shape of the protrusion 112. The protrusion 112 of the outer cover plate 11 passes through the connecting hole 124 of the inner cover plate 12. The outer diameter of the protrusion 112 is interference-fitted with the inner diameter of the connecting hole 124.
[0037] In this embodiment, the inner cover plate 12 and the outer cover plate 11 are detachably assembled together through the connecting hole 124 and the protrusion 112. The structure is simple, and the inner cover plate 12 has a disassembly function, making it easy to disassemble and clean the inner cover plate 12. In addition, the protrusion 112 is formed by the groove 111 of the outer cover plate 11, so there is no need to set up additional components to connect with the inner cover plate 12, making the structure even simpler.
[0038] In a preferred embodiment, the exhaust mechanism includes an exhaust cover 14 rotatably connected to the outer cover plate 11 and cooperating with the exhaust port 114 to block it. In this embodiment, the exhaust port 114 can be opened and closed by rotating the exhaust cover 14, making the operation simple and convenient.
[0039] In a preferred embodiment, a control component is also included for controlling the rotation and opening / closing of the exhaust cover 14. Thus, the rotation of the exhaust cover 14 can be controlled by the control component, thereby automatically opening or closing the exhaust port 114. The control component includes a rotating shaft rotatably connected to the outer cover plate 11 and a rotation controller connected to the rotating shaft. The rotation controller can be a manual control handle fixed to the rotating shaft or a rotation motor connected to the rotating shaft.
[0040] In a preferred embodiment, the lower surface of the outer cover plate 11 extends downward to form a surrounding wall 115, and the inner cover plate 12 is located in the cavity enclosed by the surrounding wall 115.
[0041] In this embodiment, the inner cover plate 12 can be hidden within the cavity enclosed by the surrounding wall 115, improving the aesthetics of the cover plate 10. Furthermore, the area of the inner cover plate 12 is slightly smaller than the area of the cavity, creating a gap between the inner cover plate 12 and the surrounding wall 115. This allows gas generated during fermentation to enter the cavity 13 through the gap and then exit through the vent 114.
[0042] In a preferred embodiment, both the inner cover plate 12 and the outer cover plate 11 are made of transparent material. This allows observation of the fermentation process inside the fermentation chamber without opening the cover plate 10, and also avoids interruption or damage to the fermentation process of the anaerobic fermentation material inside the chamber due to opening the cover plate 10. Specifically, the cover plate 10 is movably installed at the top opening, making it easy to remove the cover plate 10 from the fermentation chamber body 20 for cleaning.
[0043] In a preferred embodiment, the fermentation chamber 21 is provided with an outlet 22 at the bottom, and the bottom surface of the fermentation chamber 21 is provided with a guiding slope 23 for guiding the fluid to flow in the direction of the outlet 22. The end of the guiding surface 121 of the inner cover plate 12 is located above the end of the guiding slope 23 away from the outlet 22. The fermentation box body 20 is provided with a liquid receiving box 24 at the bottom. The outlet 22 and the liquid receiving box 24 are connected by a discharge pipe 25. One end of the discharge pipe 25 is connected to the outlet 22, and the other end of the discharge pipe 25 is connected to the liquid receiving box 24.
[0044] In this embodiment, reference Figure 9 During fermentation, residual liquid accumulates in the fermentation chamber 21. If this residual liquid is not drained in time, it will contaminate the fermented material. Therefore, this invention provides an outlet 22 at the bottom of the fermentation chamber 21. The residual liquid flows into the discharge pipe 25 through the outlet 22, and is then discharged into the collection box 24 for collection. This ensures timely discharge of the residual liquid, keeping the fermentation chamber 21 clean and preventing contamination of the fermented material. The guide slope 23 guides the fluid towards the outlet 22, which helps to accelerate the flow rate of the residual liquid and speed up its discharge. At the same time, water droplets condensed on the upper surface of the inner cover plate 12 can flow down the guide surface 121 to the edge of the inner cover plate 12 and onto the guide slope 23. The guide slope 23 then guides the water droplets to the outlet 22, from which they are discharged into the collection box 24 for collection.
