[0123] Referring to Figures 5-8As shown, in some embodiments, the cooking device can include a vacuum frying system. The vacuum frying system can be used to perform vacuum low-temperature frying on food materials. In comparison with conventional frying, the oil temperature in the vacuum low-temperature frying process is generally controlled between 80°C and 100°C, which is much lower than the 160°C to 230°C in conventional frying. Such low-temperature processing can effectively reduce the damage to heat-sensitive nutrients in food, such as vitamins and antioxidants, thereby better preserving the nutritional value of the food.

[0124] It should be noted that in a vacuum environment, the boiling point of water in food is reduced, which can evaporate rapidly, greatly shortening the drying time. Not only can it improve production efficiency, but also reduce the possible adverse changes of food due to long-term high-temperature processing, and the taste is crisp and delicious.

[0125] Because of frying in a vacuum state, the water in the food can be directly converted into steam to escape, rather than absorbing a large amount of oil. Therefore, the oil content of vacuum-fried food can be significantly lower than that of traditional fried food, generally between 10% and 20%, which helps to provide a healthier dietary option.

[0126] Low-temperature processing and rapid dehydration help to maintain the original color and flavor of the food. The aroma and flavor components in the food are not easily lost in a vacuum state, but rather are concentrated due to the reduction in water content, making the product taste crisp and the flavor rich.

[0127] During the vacuum frying process, due to the extremely low water content and the absence of oxygen, microbial growth is effectively inhibited, prolonging the shelf life of the food and facilitating storage and transportation.

[0128] This technology is suitable for a variety of food raw materials, including but not limited to fruits, vegetables, nuts, aquatic products, and poultry and livestock meat, and can produce leisure foods with unique taste and rich nutrition.

[0129] Before formal frying, the frying chamber 30 can be heated and preheated to avoid excessive oil absorption of the food material caused by cold oil frying.

[0130] During the frying process, the food material needs to go through a process of gradual heating, dehydration, coloring, and maturation from the outside to the inside. If the gas with high humidity extracted by the vacuum module is allowed to be discharged outside the box, it will increase the risk of scalding for the user. If the extracted gas is discharged into the cooking device, it will cause the internal humidity to be too high, affecting the service life of the internal components.

[0131] After frying is completed, the frying barrel 3 needs to be depressurized, and the frying oil needs to be discharged. This can easily cause the problem of food oiling after cooking.

[0132] Reference Figure 4In some embodiments, a top cover 22 can be provided on the top surface of the drawer 21. The top cover 22 can be provided at the top opening of the drawer 21. The top cover 22 can encapsulate the frying vat 3, the vacuumizing module 4, the driving module 5, the drainage module, etc. inside the vacuum frying system inside the drawer 21.

[0133] Referring to Figures 2-8 In some embodiments, the vacuum frying system can be provided inside the drawer 21. It should be noted that in other embodiments, the vacuum frying system can also be provided inside the cabinet 1, and the vacuum frying system can be provided in other regions outside the inner container 11.

[0134] Referring to Figures 5-8 In some embodiments, the vacuum frying system can include a frying vat 3. The frying vat 3 can form a frying cavity 30 inside. The frying cavity 30 can be used to place oil, and the food materials in the frying cavity 30 can be fried after the oil is heated.

[0135] In some embodiments, the vacuum frying system can include a vacuumizing module 4. The vacuumizing module 4 can be in communication with the frying cavity 30 inside the frying vat 3. The vacuumizing module 4 is used to vacuumize the frying cavity 30. Therefore, the food materials in the frying cavity 30 can be subjected to vacuum low-temperature frying treatment.

[0136] In some embodiments, the outer wall of the frying vat 3 can be provided with a vacuum joint 313 in communication with the frying cavity 30. The vacuumizing module 4 can be in communication with the vacuum joint 313.

[0178] In some embodiments, referring to Figure 13 , the oil box 76 includes an oil box shell 763. An oil containing cavity (not shown in the figure) is formed in the oil box shell 763.

[0179] In some embodiments, referring to Figure 13 , the oil box 76 includes a second oil inlet port 761. The second oil inlet port 761 is arranged on the oil box shell 763.

[0182] The oil box 76 comprises a second air outlet 765 arranged on the oil box shell 763. The second air outlet 765 is arranged at the top of the oil box shell 763. The second air outlet 765 is connected to the third air inlet 451 of the condensing assembly 45.

[0183] The gas extracted from the frying cavity 30 is discharged to the water storage box after passing through the oil box 76, the heat dissipation channel 4211, the condensing cavity and the condensing channel.

[0184] During the process of extracting gas from the frying cavity 30 by the vacuum extraction module 4, the gas flow passes through the vacuum joint 313, the second air inlet 764, the oil storage cavity, the second air outlet 765 and the third air inlet 451 in sequence to enter the condensing assembly 45. The condensing assembly 45 can more effectively condense the gas. The oil storage cavity plays a pretreatment role, reduces the burden of the condensing assembly 45 and improves the condensing effect.

[0185] The design of the oil box 76 realizes efficient vacuum extraction, prevents oil fume pollution, optimizes the gas treatment process and improves the condensing effect by reasonably arranging the second air inlet 764, the oil storage cavity, the second air outlet 765 and the communication with the condensing assembly 45, thereby significantly improving the performance of the equipment and the user experience.

[0186] With reference to Figures 16-17 The oil box 76 comprises a fifth air outlet 766. The fifth air outlet 766 is arranged on the oil box shell 763. The fifth air outlet 766 is arranged at the top of the oil box shell 763.

[0195] In some embodiments, the controller is configured to compensate the detected temperature value according to a preset temperature compensation coefficient after obtaining the temperature value detected by the temperature detection device.

[0196] Compensating the detected temperature according to the preset temperature compensation coefficient ensures the accuracy of the detected temperature due to the different arrangement positions of the temperature detection device.

[0197] Arranging the temperature detection device outside the bottom of the barrel body 31 can accurately measure the temperature of the material (mainly refers to oil) in the barrel body 31.

[0198] After obtaining the temperature values detected by the temperature detection device, the detected temperature values are compensated according to a preset temperature compensation coefficient. The temperature compensation coefficient is usually pre-set based on experimental data and actual use experience, and is used to correct the measurement error caused by environmental factors (such as external temperature change, heat conduction efficiency difference, etc.). In this way, the controller can provide more accurate and stable temperature control, so as to ensure that the temperature of the material in the barrel 31 always remains within the required range, improving the overall control accuracy and stability. This is particularly important for industrial or scientific research applications that require precise temperature control.

[0199] In some embodiments, the cooking device includes a pressure detection device. The pressure detection device is installed inside the frying cavity 30.

[0206] The first air inlet of the vacuum pump 41 can be communicated with the vacuum joint 313. The first air inlet of the vacuum pump 41 can be communicated with the frying cavity 30 through the vacuum joint 313. When the vacuum pump 41 is running, the vacuum pump 41 can perform vacuumization on the inside of the frying cavity 30 through the vacuum joint 313.

[0207] In some embodiments, referring to 13, the vacuumization module 4 can include an exhaust pipe 411. The first air outlet of the vacuum pump 41 can be communicated with the exhaust pipe 411. When the vacuum pump 41 is running, the vacuum pump 41 can discharge the extracted air through the exhaust pipe 411.

[0208] In some embodiments, one end of the exhaust pipe 411 can be connected to the first air outlet of the vacuum pump 41. The other end of the exhaust pipe 411 can extend outside the drawer 21. The end of the exhaust pipe 411 away from the vacuum pump 41 can be communicated with the outside of the drawer 21. When the vacuum pump 41 is running, the vacuum pump 41 can discharge the extracted air to the outside of the drawer 21 through the exhaust pipe 411.

[0209] In some embodiments, referring to Figure 13 , one end of the exhaust pipe 411 can be connected to the first air outlet of the vacuum pump 41. The other end of the exhaust pipe 411 can be connected to the water storage box of the water drainage module. So as to directly discharge the extracted air into the water storage box, avoid that the extracted air is too humid, causing the humidity in the space where the internal components of the cooking device are located to be too high, and condensate water to appear, and bacteria to breed if not cleaned for a long time.

[0210] During the frying or cooking process, the water in the food material will be separated out, causing the water vapor content in the air extracted by the vacuum assembly to be too high, which needs to be condensed.

[0211] In some embodiments, referring to Figure 14 、 18 -19, the vacuumization module includes a condensation assembly 45. The condensation assembly 45 forms a condensation channel inside. The gas entering the channel can be condensed in the condensation channel. The condensation assembly 45 can be disposed inside the drawer 21.

[0212] The condensation assembly 45 includes a third air inlet 451 and a third air outlet 452. The third air inlet 451 is connected to the vacuum joint 313. The third air outlet 452 is communicated with the first air inlet. The vacuum assembly can pass the gas in the frying cavity 30 through the vacuum joint 313, the third air inlet 451 into the condensation channel for condensation, and then through the third air outlet 452, the first air inlet for extraction.

[0213] In some embodiments, referring to Figure 11 , the vacuumizing module further comprises an air cooling assembly 42. The air cooling assembly 42 is used to improve the condensing capacity of the vacuum frying system.

[0214] Referring to Figure 23 , the air cooling assembly 42 comprises a heat dissipation assembly 421. The heat dissipation assembly 421 is formed with a heat dissipation channel 4211 inside, which is used to guide and control the airflow, so as to achieve an efficient heat exchange process. The design of the heat dissipation channel 4211 takes into account the path and speed of the airflow, ensuring that heat can be effectively transferred from the parts that need to be cooled to the external environment.

[0215] The heat dissipation channel 4211 is externally provided with a fourth air inlet 4212 and a fourth air outlet 4213, which are connected to the heat dissipation channel 4211. Both of these interfaces are designed to connect the heat dissipation channel 4211, and they are located outside the heat dissipation channel 4211 and maintain connectivity between each other.

[0216] The fourth air inlet 4212 is connected to the vacuum joint 313. This means that it can use the external suction force to introduce the gas in the frying cavity 30 into the heat dissipation channel 4211. This design helps to enhance the strength of the airflow, further improving the heat dissipation efficiency. The fourth air outlet 4213 is connected to the third air inlet 451. A continuous air circulation path is formed, so that the air after heat dissipation can be smoothly discharged outside the system.

[0217] In order to further enhance the working performance of the air cooling assembly 42, the air cooling assembly 42 comprises an air cooling fan 42. The air cooling fan 42 is arranged on one side of the heat dissipation assembly 421. Its main role is to promote the flow of air in the heat dissipation air duct. By generating an additional air pressure difference, the air cooling fan 42 can more efficiently remove the heat in the heat dissipation air duct, thereby significantly improving the overall cooling effect of the system. Especially in the case of high heat load or requiring rapid cooling, the air cooling fan 42 plays a particularly important role, it can effectively improve the condensation efficiency of the extracted gas, and ensure that the equipment can stably operate within a safe temperature range.

[0218] In some embodiments, referring to Figure 11 , the vacuumizing module comprises a condenser 43. The condenser 4342 can be arranged inside the drawer 21. The condenser 4342 can be arranged on one side of the frying barrel 3. The condenser 4342 can be formed with a condensation cavity inside (not shown in the figure). The condenser 4342 can be externally provided with a first interface 431 and a second interface 422, which are connected to the condensation cavity. The first interface 431 can be connected to the vacuum joint 313. The first air outlet of the vacuum pump 41 can be connected to the second interface 422.

[0219] In some embodiments, referring to Figure 8The condensing cavity can be provided with a condensing pipe (not shown in the figure). An external water source can enter the condensing pipe to condense the air in the condensing cavity, cool the condenser 4342, and improve the condensing efficiency of the condenser 4342.

[0220] In some embodiments, the condenser 4342 can be provided with a first water inlet pipe 4336 and a first water outlet pipe 434. One end of the condensing pipe 423 can extend out of the condenser 4342 and be connected to the first water inlet pipe 4336, so that one end of the condenser 4342 can be connected to the water purification box through the first water inlet pipe 4336. The other end of the condensing pipe 423 can extend out of the condenser 4342 and be connected to the first water outlet pipe 434, so that the other end of the condenser 4342 can be connected to the water purification box through the first water outlet pipe 434.

[0221] Therefore, the water in the water purification box can enter the condensing pipe 423 through the first water inlet pipe 4336, condense the air in the condensing cavity, and then return to the water purification box through the first water outlet pipe 434, thereby forming a condensing water circulation between the condensing pipe 423 and the water purification box.

[0222] The water path of the condenser 43 is cooled by using the cold and clean water in the water storage box to cool the condenser 43, and the water circulation in the water storage box is continuously or intermittently driven by the circulating condensing water pump.

[0223] When the vacuum pump 41 is running, the vacuum pump 41 can draw a vacuum in the frying cavity 30 through the vacuum joint 313 and the condensing cavity, so that the gas in the frying cavity 30 can enter the condensing cavity through the vacuum joint 313 and the first interface 431, be condensed, and then be discharged through the vacuum pump 41, which can improve the condensing performance of the vacuum pump 41 when drawing a vacuum, and is beneficial to improving the vacuum degree of the frying barrel 3.

[0224] In some embodiments, the technical solution can select one or a combination of the condensing assembly 45, the condenser 43, and the air-cooled assembly 42 for condensing work.

[0225] Referring to Figure 8 , 11 , 13, the technical solution is described in which the gas drawn by the vacuum assembly passes through the air-cooled assembly 42, the condenser 43, and the condensing assembly 45 in sequence.
