[0039] 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.

[0040] 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.

[0041] like Figures 1 to 13 As shown, this utility model provides a multifunctional fermentation box, comprising:

[0042] Fermentation chamber body 1, which is provided with fermentation chamber 11;

[0043] Temperature sensor 4 is used to detect the temperature of the fermentation chamber 11;

[0044] The temperature control mechanism 3 is used to maintain the temperature of the fermentation chamber 11.

[0045] Odor removal mechanism, used to remove odors from inside fermentation chamber 11;

[0046] An observation mechanism is set on the periphery of the fermentation chamber body 1 to observe the fermentation situation inside the fermentation chamber 11 from multiple angles.

[0047] The control circuit board 6 is used to control the operation of the constant temperature regulating mechanism 3 according to the temperature detected by the temperature sensor 4, so as to keep the fermentation chamber 11 in a constant temperature state.

[0048] In this embodiment, fermentation is carried out by placing the fermentation container in the fermentation chamber 11. A support frame for fixing the fermentation container can be placed at the bottom of the fermentation chamber 11, and the support frame can be folded for storage. After the fermentation container is placed, the constant temperature regulation mechanism 3 is turned on. The constant temperature regulation mechanism 3 heats / cools the fermentation chamber 11. During the fermentation process, the temperature inside the fermentation chamber 11 is monitored in real time by the temperature sensor 4. When the temperature inside the fermentation chamber 11 is above the set fermentation temperature value, the control circuit board 6 controls the constant temperature regulation mechanism 3 to work, and the constant temperature regulation mechanism 3 cools the fermentation chamber 11. When the temperature inside the fermentation chamber 11 is below the set fermentation temperature value, the control circuit board 6 controls the constant temperature regulation mechanism 3 to work, and the constant temperature regulation mechanism 3 heats the fermentation chamber 11, thereby keeping the fermentation chamber 11 in a constant temperature state and maintaining the constant temperature required for fermentation. By setting an odor removal mechanism, it is easy to remove odors inside the fermentation box in a timely manner, improving the user experience. By setting an observation mechanism, the fermentation process of the fermentation chamber 11 can be observed and recorded from multiple angles, and abnormalities in fermentation can be detected in a timely manner, making the operation more convenient and faster.

[0049] In a preferred embodiment, the constant temperature control mechanism 3 includes a thermoelectric cooler 31, a cooling conductive component 32, and a heat dissipation component 33. The cold end face of the thermoelectric cooler 31 is connected to the cooling conductive component 32, and the hot end face of the thermoelectric cooler 31 is connected to the heat dissipation component 33. The fermentation chamber body 1 is provided with a cooling conductive cavity and a heat dissipation cavity that are not interconnected. The thermoelectric cooler 31 is disposed between the cooling conductive cavity and the heat dissipation cavity. The cooling conductive component 32 is disposed towards the cooling conductive cavity, and the heat dissipation component 33 is disposed towards the heat dissipation cavity. The side wall of the fermentation chamber 11 is provided with a grid panel 16 that connects the cooling conductive cavity and the fermentation chamber 11. The side of the grid panel 16 facing the cooling conductive cavity is provided with a circulating fan 34 for circulating the air inside the fermentation chamber 11 and the air inside the cooling conductive cavity.

[0050] In this embodiment, the thermoelectric cooler 31 determines whether to cool or heat on the same surface by changing the polarity of the direct current. It consists of two ceramic plates with N-type and P-type semiconductor materials in between, connected in series in the circuit. The working principle of the thermoelectric cooler 31 is as follows: when an N-type semiconductor material and a P-type semiconductor material are connected to form an electrical couple, a direct current is applied to this circuit, resulting in energy transfer. The current flows from the N-type element to the P-type element, absorbing heat at the junction, becoming the cold junction, and flows from the P-type element to the N-type element, releasing heat at the junction, becoming the hot junction. Therefore, the thermoelectric cooler 31 can both cool and heat.

[0051] This embodiment utilizes a semiconductor cooling chip 31 to maintain a constant temperature in the fermentation chamber 11 (i.e., the fermentation temperature required for the material to be fermented). The specific principle is as follows: The temperature inside the fermentation chamber 11 is monitored in real time by a temperature sensor 4. When the temperature sensor 4 detects that the temperature of the fermentation chamber 11 is lower than the set fermentation temperature, the control circuit board 6 controls the cold and hot ends of the semiconductor cooling chip 31 to reverse their polarities through a reverse power supply, turning the cold end into the hot end. When the semiconductor cooling chip 31 starts working, the air in the fermentation chamber 11 enters the cooling chamber through a circulating fan 34. After the air is heated by contacting the cooling component 32, it is blown back to the fermentation chamber 11 by the circulating fan 34, exchanging hot and cold energy with the air in the fermentation chamber 11 to complete one cycle, until the temperature of the fermentation chamber 11 rises or falls to the fermentation temperature. The control circuit board 6 controls the semiconductor cooling chip 31 to stop working, keeping the fermentation chamber 11 at a constant temperature. When the temperature sensor 4 detects that the temperature of the fermentation chamber 11 is higher than the set fermentation temperature, the control circuit board 6 controls the cold and hot ends of the semiconductor cooling chip 31 to reverse their polarities through a reverse power supply, turning the hot end into the cold end. The control circuit board 6 then controls the semiconductor cooling chip 31 to work, and the air in the fermentation chamber 11 enters the cooling chamber through the circulating fan 34. After the hot air comes into contact with the cooling component 32 and is cooled, it returns to the fermentation chamber 11 through the circulating fan 34, exchanging hot and cold energy with the air in the fermentation chamber 11 to complete one cycle. This cycle continues until the temperature of the chamber drops to the set fermentation temperature, at which point the control circuit board 6 controls the semiconductor cooling chip 31 to stop working, thus maintaining the constant temperature of the fermentation chamber 11. Therefore, this invention utilizes the cooperation of the semiconductor cooling chip 31, the temperature sensor 4, and the control circuit board 6 to achieve constant temperature control of the fermentation chamber 11, not only maintaining a constant fermentation temperature but also effectively reducing energy consumption. In addition, traditional fermentation boxes generally have heating and cooling devices installed at the bottom of the fermentation chamber 11 for heating and cooling. This method has the defect of uneven heating and cooling. However, this utility model uses a circulating fan 34 to circulate the air inside the fermentation chamber 11 and the air inside the cooling chamber, so that the airflow inside the fermentation chamber 11 circulates and ensures that the temperature is consistent in all parts of the fermentation chamber 11, achieving the effect of uniform temperature distribution.

[0052] In this embodiment, a detection hole 17 is provided on the side wall of the fermentation chamber 11, and the temperature sensor 4 monitors the temperature inside the fermentation chamber 11 through the detection hole 17. In order to improve the cooling effect, a heat dissipation hole 15 communicating with the heat dissipation chamber is provided on the rear side of the fermentation box body 1. The air of the external environment enters the heat dissipation chamber through the cooling fan 35, exchanges heat with the heat dissipation component 33, and is then discharged to the external environment through the heat dissipation hole 15, forming a heat dissipation cycle, thereby reducing the temperature of the hot end and improving the cooling efficiency.

[0053] It is understandable that the semiconductor cooling chip 31 can realize both cooling and heating functions, thus eliminating the need for an additional refrigeration system, greatly simplifying the structure of the fermentation chamber and reducing costs. Simultaneously, the semiconductor cooling chip 31 enables the fermentation chamber to function as a refrigerator, allowing it to be used as a small freezer. This allows fermented food to be refrigerated and preserved as needed, and it can also be used to refrigerate some foods and beverages, such as red wine.

[0054] Specifically, the cooling component 32 includes an integrally formed cooling block 321 and cooling fins 322. One side of the cooling block 321 is connected to the cold end face of the thermoelectric cooler 31, and the other side of the cooling block 321 is connected to the cooling fins 322. The heat dissipation component 33 includes an integrally formed heat dissipation block 331 and heat dissipation fins 332. One side of the heat dissipation block 331 is connected to the hot end face of the thermoelectric cooler 31, and the other side of the heat dissipation block 331 is connected to the heat dissipation fins 332. By designing the cooling block 321 and cooling fins 322 as an integral form, and the heat dissipation block 331 and heat dissipation fins 332 as an integral form, heat loss can be reduced, the overall area of ​​the thermostatic control mechanism 3 can be reduced, and space can be saved.

[0055] To avoid energy loss caused by heat exchange, the thermostatic control mechanism 3 also includes a foam layer 38, which has fixing holes in which the semiconductor cooling chip 31 is embedded. The foam layer 38 completely isolates the cold end and the hot end of the semiconductor cooling chip 31, thereby avoiding energy loss caused by heat exchange.

[0056] Specifically, the fermentation chamber also includes a middle partition 36 and a cover frame 37. The middle partition 36 is disposed in the rear internal cavity of the fermentation chamber body 1 to divide the rear internal cavity of the fermentation chamber body 1 into a heat dissipation cavity and a partition cavity. The cover frame 37 is disposed in the partition cavity and has a cover cavity 371 with openings at both ends. The cover cavity 371 forms the cooling cavity. The middle partition 36 has an opening. One end of the cover frame 37 extends into the opening. The foam layer 38 is sealed and embedded in the opening at one end of the cover frame 37. The cooling component 32 and the circulating fan 34 are both located in the cover cavity 371, and the heat dissipation component 33 is located in the heat dissipation cavity.

[0057] In a preferred embodiment, the grille panel 16 includes a plurality of spaced-apart horizontal grille pieces 161, with air ducts 162 formed between the spaced-apart horizontal grille pieces 161. The horizontal grille pieces 161 are inclined downward from the back side of the grille panel 16 toward the front side of the grille panel 16, and the end of the horizontal grille piece 161 near the back side of the grille panel 16 is provided with a water-blocking flange 163.

[0058] After prolonged use, dirt will accumulate on the grille panel 16 of the fermentation tank body 1, which can affect the airflow from the circulating fan 34. Therefore, the grille panel 16 is detachably installed at the air vent of the fermentation tank body 1 for easy disassembly and cleaning. The horizontal grille plates 161 are inclined downwards, preventing water from flowing into the circulating fan 34 behind the grille panel 16. Simultaneously, the water-blocking flange 163 prevents water from flowing from the horizontal grille plates 161 towards the circulating fan 34, further reducing water splashing onto the circulating fan 34. Furthermore, the inclined design of the horizontal grille plates 161 creates a downward-sloping airflow duct 162 between them, meaning the airflow entering and exiting the grille panel 16 is inclined, which helps reduce wind resistance and noise.

[0059] The assembly structure between the grille panel 16 and the air vent can be as follows: a slot 164 is provided on the upper back of the grille panel 16, and a locking post 18 is formed at the upper edge of the air vent of the fermentation chamber body 1 to cooperate with the slot 164. The slot 164 and the locking post 18 engage to achieve detachable installation of the grille panel 16 and the fermentation chamber body 1. An insert 165 is provided on the lower back of the grille panel 16, and an insertion hole 19 is formed at the lower edge of the air vent of the fermentation chamber body 1 to cooperate with the insert 165. The mutual cooperation between the insert 165 and the insertion hole 19 ensures a reliable connection between the grille panel 16 and the fermentation chamber body 1. In a preferred embodiment, the odor removal mechanism includes an odor removal box 8, in which an activated carbon plate is installed. A groove for fixing the odor removal box 8 is provided on the side wall of the fermentation chamber 11, and the odor removal box 8 is detachably installed in the groove. By installing a deodorizing box 8 on the side wall of the fermentation chamber 11, the activated carbon plate inside the deodorizing box 8 can absorb odors in the fermentation chamber 11, ensuring that no unpleasant smells occur during fermentation and guaranteeing the quality and efficiency of fermentation. The deodorizing box 8 is removable, making it easy to replace the internal activated carbon plate. Specifically, in this embodiment, the deodorizing box 8 is opposite to the circulating fan 34 inside the grille panel 16, so that the air blown out by the circulating fan 34 can effectively remove odors from the fermentation chamber body 1 by passing through the odor-absorbing substances inside the deodorizing box 8.

[0060] In a preferred embodiment, the observation mechanism includes a visualization glass 9, and windows are provided on three sides of the fermentation chamber 11, with each window fitted with a visualization glass 9.

[0061] In this embodiment, by providing visual glass 9 on the front and left and right sides of the fermentation chamber body 1, the user can observe the changes in the fermentation state in the fermentation chamber 11 from three directions at any time without opening the lid. It is also convenient to observe and record the details of the fermentation process, and any abnormalities in the fermentation can be detected in time. The operation is more convenient and faster, and the fermentation process of the fermented material in the chamber is not interrupted or damaged due to opening the lid.

[0062] In a preferred embodiment, the fermentation box body 1 has an opening at the top, the opening is equipped with a transparent cover plate 2, and the outside of the fermentation box body 1 is provided with a storage rack 13 for placing the transparent cover plate 2.

[0063] In this embodiment, the transparent cover 2 is movably installed at the opening. After opening the transparent cover 2, it can be placed on the storage rack 13 for easy user operation. During fermentation, the internal condition of the fermentation chamber 11 can be observed with the help of the transparent cover 2.

[0064] In a preferred embodiment, the fermentation chamber 11 is further provided with a functional module, which includes a high-definition camera, a communication module and a lighting device, and the functional module is electrically connected to the control circuit board 6.

[0065] In this embodiment, a high-definition camera is installed to collect real-time data on the fermentation process within the fermentation chamber 11. A communication module is also included to transmit the collected information to remote terminals such as mobile phones or computers for convenient remote monitoring. The lighting device facilitates user observation of the interior of the fermentation chamber 11 and also assists the high-definition camera in capturing data. Specifically, the lighting device is an LED lamp 14, which offers energy-saving and environmentally friendly advantages. The communication module includes a Wi-Fi communication module, a 4G communication module, and a Bluetooth communication module.

[0066] In a preferred embodiment, the fermentation chamber body 1 is provided with an operation panel 7 on its top, and the operation panel 7 is electrically connected to the control circuit board 6. In this embodiment, the equipment inside the fermentation chamber body 1 is regulated by the control circuit board 6, and the control circuit board 6 is operated by the operation panel 7, so as to achieve precise control of the temperature inside the fermentation chamber, ensuring the ease of use of the device and making it easy for operators to quickly get started.

[0067] In a preferred embodiment, the fermentation chamber 11 is further provided with a liquid receiving box 51 detachably installed at the bottom of the fermentation chamber body 1 and a drain pipe 52 connected to the liquid receiving box 51. The bottom of the fermentation chamber 11 is provided with a residual liquid outlet 12. One end of the drain pipe 52 is connected to the residual liquid outlet 12, and the other end of the drain pipe 52 is connected to the liquid receiving box 51. The drain pipe 52 is inclined downward toward the liquid receiving box 51.

[0068] In this embodiment, a residual liquid outlet 12 is provided in the fermentation chamber 11. The residual liquid flows into the drain pipe 52 through the outlet 12, and is then discharged into the collection box 51 for collection. This ensures timely discharge of the residual liquid, thereby keeping the fermentation chamber 11 clean and preventing contamination of the fermented material. The collection box 51 is detachably connected to the fermentation tank body 1, greatly facilitating the user to check the residual liquid status and clean it up promptly.
