[0132] Referring to Figures 5-8 In some embodiments, the cooking device can include a vacuum frying system. The vacuum frying system can be used for vacuum low-temperature frying of food materials. Compared with conventional frying, the oil temperature in the vacuum low-temperature frying process is usually controlled between 80°C and 100°C, which is much lower than the conventional frying temperature of 160°C to 230°C. 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.

[0133] It should be noted that in a vacuum environment, the boiling point of water in food is reduced, and water can evaporate rapidly, greatly shortening the drying time. Not only can the production efficiency be improved, but also the undesirable changes that may occur in food due to long-term high-temperature processing can be reduced, and the food has a crisp and delicious taste.

[0134] Due to frying in vacuum state, the water in food can be directly converted into steam to escape, instead of 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%-20%, which helps to provide a healthier dietary option.

[0135] 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 the vacuum state, but are instead concentrated due to the reduction in moisture, resulting in a more crispy texture and rich flavor of the product.

[0136] During vacuum frying, 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.

[0137] 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 snack foods with unique taste and rich nutrition.

[0138] Before formal frying, the frying chamber 30 can be heated for preheating to avoid excessive oil absorption of the food caused by cold oil frying.

[0139] During frying, the food 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 interior of the cooking device, it will cause the internal humidity to be too high, affecting the service life of the internal components.

[0140] 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.

[0141] Referring to Figure 4 In some embodiments, a top cover 22 can be provided on the top surface of the drawer 21. The top cover 22 can be provided on the top opening of the drawer 21. The top cover 22 can encapsulate the frying barrel 3, the vacuum module 4, the driving module 5, the drainage module, etc. in the vacuum frying system inside the drawer 21.

[0142] 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 box 1, and the vacuum frying system can be provided in other areas outside the inner container 11.

[0143] Referring to Figures 5-8As shown, in some embodiments, the vacuum frying system can include a frying barrel 3. The frying barrel 3 can form a frying cavity 30 inside. The frying cavity 30 can be used to place oil, and the oil can be heated to fry food in the frying cavity 30.

[0144] 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 in the frying barrel 3. The vacuumizing module 4 can be used to vacuumize the frying cavity 30. Thus, the food in the frying cavity 30 can be vacuum low-temperature fried.

[0145] In some embodiments, the frying barrel 3 can be provided with a vacuum joint 313 on the outer wall of the frying barrel 3, which is in communication with the frying cavity 30. The vacuumizing module 4 can be in communication with the vacuum joint 313. The vacuumizing module 4 can extract air in the frying cavity 30 through the vacuum joint 313, thereby achieving vacuumization of the frying cavity 30.

The end of the exhaust pipe 411 away from the vacuum pump 41 can be in communication with the outside of the drawer 21. When the vacuum pump 41 is running, the vacuum pump 41 can be able to exhaust the extracted gas through the exhaust pipe 411 to the outside of the drawer 21.

[0218] In some embodiments, referring to Figure 13 , one end of the exhaust pipe 411 can be connected to the first gas 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. In order to directly drain the extracted air into the water storage box, avoid the extracted air being too humid, causing the space where the internal components of the cooking device are located to be too humid, resulting in condensation water, and long-term neglect causing bacterial growth.

[0219] During the frying or cooking process, the water in the food material will be released, causing the water vapor content in the gas extracted by the vacuum assembly to be too high, which needs to be condensed.

[0220] In some embodiments, referring to Figure 14 , 18 -19, the vacuum extraction module includes a condensation assembly 45. The condensation assembly 45 has a condensation passage formed therein.

The design of the heat dissipation passage 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.

[0224] The heat dissipation channel 4211 has a fourth air inlet 4212 and a fourth air outlet 4213 outside the heat dissipation channel 4211. Both 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.

[0225] The fourth air inlet 4212 is connected to the vacuum joint 313. This means that it can use external suction to introduce gas in the frying cavity 30 into the heat dissipation channel 4211. This design helps to enhance the air flow intensity and further improve the heat dissipation efficiency. The fourth air outlet 4213 is connected to the third air inlet 451. A continuous air flow circulation path is formed, so that the air after heat dissipation can be smoothly discharged outside the system.

[0226] In order to further enhance the working performance of the air cooling assembly 42, the air cooling assembly 42 includes an air cooling fan 42. The air cooling fan 42 is arranged on one side of the heat dissipation assembly 421. Its main function 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 heat from 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 an important role, which can effectively improve the condensation efficiency of the extracted gas, and ensure that the equipment can operate stably within a safe temperature range.

The first air outlet of the vacuum pump 41 can be connected to the second interface 422.

[0228] In some embodiments, referring to Figure 8 , a condensation pipe (not shown in the figure) can be arranged in the condensation cavity. An external water source can enter the condensation pipe to condense the air in the condensation cavity, cool the condenser 4342, and improve the condensation efficiency of the condenser 4342.

[0230] 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 condensate water circulation between the condensing pipe 423 and the water purification box.

[0231] 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 condensate pump.

[0232] 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 during vacuuming, and is beneficial to improving the vacuum degree of the frying barrel 3.

[0233] 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.

[0234] Referring to Figure 8 , 11 , 13, the technical solution is described in which the vacuum assembly draws gas which sequentially passes through the air-cooled assembly 42, the condenser 43, and the condensing assembly 45. Of course, the above three assemblies can be combined in other ways. For example, the positions of the condenser 43 and the air-cooled assembly 42 can be adjusted.

[0235] Referring to Figure 11 , the condenser 4342 can be arranged on one side of the frying barrel 3. The condensing assembly 45 is arranged below the condenser 43 to facilitate the collection of condensate water from the condensing channel.

[0236] The vacuum joint 313 is in communication with the fourth air inlet 4212 of the air-cooled assembly 42, the fourth air outlet 4213 is in communication with the first joint of the condenser 43, the second joint is in communication with the third air inlet 451 of the condensing assembly 45, the third air outlet 452 is in communication with the first air inlet of the vacuum assembly, and the first air outlet is in communication with the water storage box.

[0237] Based on the above, referring toFigure 11 , 12 The red arrow in the middle and Figure 13 As indicated by the blue arrow, the gas extracted from the frying chamber 30 is drawn out through the vacuum assembly and then sequentially enters the air-cooling assembly 42, the condenser 43, and the condensing assembly 45 for condensation. Finally, it is discharged into the water storage box through the first gas outlet.

[0238] The reason for venting the extracted air to the water storage box is to prevent the extracted air from remaining too humid, which is a safety feature for the overall components. Of course, in some embodiments, it can also be connected to the outside air through the first air outlet.

[0239] The condensation system of the cooking apparatus of this application adopts a combination of air cooling and water cooling to condense the vacuum system during the cooking process.

[0240] Pipe A, which connects to the fryer 3 for vacuuming, is connected to the oil storage box 76. The oil storage box 76 is then connected to pipe B, which is connected to the fourth air inlet of the air-cooling assembly 42. After passing through the air-cooling assembly 42, the hot steam exits from the fourth air outlet of the air-cooling assembly 42 and connects to the first connector (air inlet) of the condenser 43 via pipe C. The second connector (air outlet) of the condenser 43 is connected to the condensing assembly 45 via pipe D. The third air outlet 452 of the condensing assembly 45 is connected to the vacuum assembly via pipe E.

[0241] The third air inlet 451 and the third air outlet 452 of the condensing component 45 are connected by a partition, which increases the exhaust path and allows the condensate to be better condensed and deposited in the condensate tank.

[0242] In some embodiments, the third outlet 452 is connected to the first inlet of the vacuum pump. The first inlet of the vacuum pump is connected to the top region of the condensing assembly 45. The vacuum pump can extract gas from the condensing assembly 45 through the third outlet 452, and then extract gas from the frying chamber 30 through the third inlet 451, the condensing chamber, and the vacuum connector 313. This allows the gas in the frying chamber 30 to enter the condensing chamber through the first connector for condensation, and then enter the condensing assembly 45 through the second interface for secondary condensation. Finally, the gas is discharged through the third outlet 452 and the vacuum pump.

[0243] In some embodiments, refer to Figure 14 The condenser assembly 45 also includes a first drain outlet 453. The first drain outlet 453 is used to drain the condensate inside the condenser assembly 45.

[0245] The inner side wall along the width direction in the condensation channel is provided with a flow guide component 454 extending from one inner side wall of the condensation channel to the other inner side wall of the condensation channel.

[0246] By arranging the bending structure in the condensation channel, the path of the condensation channel is increased, and the condensation effect is improved.

[0247] Referring to Figure 19 , after the gas enters the condensation assembly 45, it flows along the red arrow path, and is fully condensed and radiated in the condensation channel of the condensation assembly 45. In some embodiments, the bottom surface of the condensation channel is inclined from the third air inlet 451 to the first drainage port 453.

[0248] Referring to Figure 19 , the condensate condensed in the middle of the condensation assembly 45 is inclined from the third air inlet 451 to the first drainage port 453, and is inclined from the third air outlet 452 to the first drainage port 453. The first drainage port 453 is arranged as the lowest point. So that the condensate will converge to the first drainage port 453.

[0249] In this way, the overall condensate will converge to the lowest point of the overall ground, that is, the first drainage port 453; in order to reduce the amount of residual water in the condensation assembly 45 as much as possible, the bottom is designed as a pit.

[0250] Referring to Figure 13 , 14 As shown in some embodiments, the vacuum frying system can include a drainage module 8.

The drainage switch valve 64 can be disposed in a pipeline between the condensing assembly 45 and the drainage water pump 63. The drainage switch valve 64 can be used to open and close the drainage passage 6281. When the drainage switch valve 64 closes the drainage passage 6281, the inside of the condensing assembly 45 can be sealed from the water storage box 61, so as to facilitate vacuumizing the inside of the condensing assembly 45.

[0256] When the drainage switch valve 64 opens the drainage passage 6281, the inside of the condensing assembly 45 can be communicated with the inside of the water storage box 61. The drainage water pump 63 can draw water in the condensing assembly 45 and discharge the drawn water into the inside of the water storage box 61.

[0257] Referring to Figure 21 In some embodiments, the inside of the water storage box 61 can be provided with a water inlet head 821 extending upward. The top end of the water inlet head 821 can communicate with the top region in the water storage box 61.

[0258] When the drainage switch valve 64 opens the drainage passage 6281 and the drainage water pump 63 starts to operate, the drainage water pump 63 can draw water in the condensing assembly 45 and discharge the drawn water into the water storage box 61 through the drainage passage 6281 and the water inlet head 821.

[0259] Referring to Figure 21 In some embodiments, the drainage module 8 can include a second storage tank 85. The second storage tank 85 can be disposed in the drawer 21.

[0260] When the water storage box 61 is disposed in the second storage tank 85, the water inlet connector 851 can be connected with the water inlet head 821 to connect the drainage passage 6281 with the water inlet head 821, so as to discharge water in the condensing assembly 45 into the inside of the water storage box 61.

[0261] In some embodiments, a water level detection assembly 823 can be arranged on the inner wall of the water storage box 61. The water level detection assembly 823 can be used to detect the water level in the water storage box 61. The water level detection assembly 823 can be electrically connected to the controller 61. When the water level in the water storage box 61 reaches a preset height, the user can be reminded to take out the water storage box 61 from the second storage box 85, and the user can be reminded to clean the water storage box 61 in time.

[0262] In some embodiments, referring to 16, 17, the cooking device comprises a pressure relief module 8. The pressure relief module 8 is used to relieve the pressure of the frying cavity 30.

[0264] In some embodiments, one end of the pressure relief channel 81 is connected to the fifth air outlet 766, and the other end of the pressure relief channel 81 is connected to the air; when the pressure is relieved, the air enters the frying cavity 30 through the oil box 76.

[0265] The gas passes through the oil box 76 as a transition from the frying cavity 30, and then enters the frying cavity 30 along the pressure relief channel 81. Such a design not only guarantees the need for safe pressure relief, but also takes into account the problem of preventing high-temperature oil from being directly sprayed out to cause safety hazards.

[0266] In some embodiments, the cooking device further comprises a pressure relief switch 82. The pressure relief switch 82 is installed on the pressure relief channel 81.
