Description

Technical Field

[0001] The present invention relates to the technical field of cooking equipment, and in particular to a cooking device. Background Art

[0002] With the improvement of living standards, cooking devices have gradually become an indispensable electrical appliance in home life. A cooking device, such as an oven, a steamer or a steam oven, is a cooking device that holds food in a closed space and heats and cooks the food.

[0003] In the related cooking device, the cooking device includes a box body and an inner pot arranged in the box body. A cooking cavity is formed inside the inner pot, and the food in the cooking cavity is cooked at high temperature. In order to enrich the functions of the cooking device, a frying barrel is provided to fry the food at low temperature. The cooking device also includes structures such as a frying barrel, a vacuum module, and an oil drain module. During the cooking process, the vacuum module is used to evacuate the frying barrel to reduce the air pressure in the frying barrel.

[0004] When cooking is completed, the frying barrel will be depressurized and the oil will be drained. However, at this time, due to the influence of the air pressure in the frying barrel, the oil in the frying barrel will be pressed into the food, causing the food to return oil and resulting in poor cooking results.

[0005] In view of this, this application is filed. Summary of the invention

[0006] During the cooking process, the present application controls the vacuum module to evacuate the frying chamber; after the cooking is completed, the oil control switch is first controlled to be turned on, so that the oil in the frying chamber flows into the oil box through the first oil outlet; and then the pressure relief switch is controlled to be turned on to relieve the pressure in the frying chamber, thereby avoiding the situation where the pressure is relieved first and then the food re-absorbs the oil, which affects the taste of the food.

[0015] In the above scheme, after cooking is finished, the oil is first discharged into the oil box by its own gravity, and then the pressure is released, so as to avoid the food re-absorbing the oil after the pressure is released, which affects the taste of the food.

[0016] In some embodiments, the cooking device further comprises:

[0017] A heating assembly is disposed at the bottom of the barrel and is used to heat the frying cavity;

[0139] Reference Figure 5-8 As shown, in some embodiments, the cooking device may include a vacuum frying system. The vacuum frying system can be used to perform vacuum low-temperature frying on the food. Compared with conventional frying, the oil temperature during vacuum low-temperature frying is usually controlled between 80°C and 100°C, which is much lower than the 160°C to 230°C of conventional frying. Such low-temperature treatment 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.

[0140] It should be noted that in a vacuum environment, the boiling point of water in food is lowered and can evaporate quickly, which greatly shortens the drying time. This not only improves production efficiency, but also reduces the adverse changes that may occur in food due to long-term high-temperature treatment, and makes the food crispy and delicious.

[0141] Because the food is fried under vacuum, the moisture in the food can be directly converted into steam and escaped 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% and 20%, which helps to provide a healthier diet option.

[0142] Low temperature treatment and rapid dehydration help to maintain the original color and flavor of food. The aroma and flavor components in food are not easily lost in a vacuum state, but will be concentrated due to the reduction of water, making the product taste crispier and more flavorful.

[0143] During the vacuum frying process, due to the extremely low moisture content and the fact that it is carried out in an oxygen-free environment, the growth of microorganisms can be effectively inhibited, the shelf life of food can be extended, and it is easy to store and transport.

[0144] This technology is applicable to a variety of food raw materials, including but not limited to fruits, vegetables, dried fruits, aquatic products, and livestock and poultry meat, and can produce snack foods with unique taste and rich nutrition.

[0145] Before frying, the frying chamber 30 may be preheated to prevent excessive oil absorption by the food due to frying in cold oil.

[0146] During the frying process, the food needs to go through a gradual process of heating, dehydration, coloring and maturation from the outside to the inside. The air extracted by the vacuum module contains a high humidity. If the air extracted by the vacuum module is allowed to be discharged outside the box, the risk of burns to the user will increase. If the extracted air is discharged into the cooking device, the internal humidity will be too high, affecting the service life of the internal components.

[0147] After frying, the frying barrel 3 needs to be depressurized and the fried oil needs to be discharged, which easily leads to the problem of oil backflow of ingredients after cooking.

[0199] The gas extracted from the frying chamber 30 passes through the oil box 76, the heat dissipation channel 4211, the condensation chamber, and the condensation channel and is then discharged to the water storage box.

[0200] During the process of vacuuming the frying chamber 30 by the vacuum module 4, the airflow sequentially passes through the vacuum joint 313, the second air inlet 764, the oil chamber, the second air outlet 765, and the third air inlet 451 to enter the condensation assembly 45, and the condensation assembly 45 can more effectively condense the gas. The oil chamber plays a role of pretreatment, reduces the burden of the condensation assembly 45, and improves the condensation effect.

[0201] The design of the oil box 76 achieves multiple functions such as efficient vacuuming, prevention of oil fume pollution, optimization of gas treatment process and improvement of condensation effect through the reasonable arrangement of the second air inlet 764, the oil containing cavity, the second air outlet 765 and the connection with the condensation component 45, which significantly improves the performance of the equipment and the user experience.

[0210] In some embodiments, the cooking device includes a temperature detection device for detecting the temperature in the frying cavity 30. In some embodiments, the temperature detection device is disposed on the outside of the bottom of the barrel 31.

[0211] In some embodiments, the controller is configured to, after acquiring the temperature value detected by the temperature detection device, compensate the detected temperature value according to a preset temperature compensation coefficient.

[0212] The detected temperature is compensated according to a preset temperature compensation coefficient, thereby ensuring the problem of inaccurate detected temperature caused by different setting positions of the temperature detection device.

[0213] The temperature detection device is installed on the outside of the bottom of the barrel body 31 so as to accurately measure the temperature of the material (here mainly refers to the oil) in the barrel body 31.

[0214] After obtaining the temperature values ​​detected by the temperature detection device, these detected temperature values ​​are compensated according to the 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 measurement errors caused by environmental factors (such as external temperature changes, differences in heat conduction efficiency, etc.). In this way, the controller can provide more accurate and stable temperature control, thereby ensuring that the temperature of the material in the barrel 31 is always maintained within the required range, improving the overall control accuracy and stability. This is especially important for industrial or scientific research applications that require precise temperature control.

[0215] In some embodiments, the cooking device includes a pressure detection device. The pressure detection device is installed in the frying cavity 30.

[0216] The pressure detection device is installed inside the frying cavity 30, and the specific position can be selected on the upper side wall of the frying cavity 30. This arrangement can more effectively monitor the pressure changes in the frying cavity 30.

[0217] By accurately monitoring the pressure in the frying chamber 30, the heat transfer efficiency during the frying process can be better controlled to ensure the quality and safety of food processing. In addition, such a design also helps to prevent safety hazards caused by excessive pressure, such as equipment damage or explosion risks, thereby ensuring the safety of operators. In actual applications, the position and number of pressure detection devices can also be adjusted according to different process requirements to meet specific process parameter control requirements.

[0218] In some embodiments, the frying barrel 3 may include a heating component. The heating component may be arranged on the peripheral side wall of the barrel body 31. The heating component may adopt an electric heating structure. When the heating component is working, the heating component can heat up the inside of the frying cavity 30, thereby heating the oil inside the frying cavity 30, so that the food in the frying cavity 30 can be vacuum fried at low temperature.

[0219] In some embodiments, reference Fig.15The heating assembly may include a heating tube 315. The heating tube 315 may be arranged around the peripheral side wall of the barrel body 31. The heating tube 315 may be arranged around the outer periphery of the frying cavity 30.

[0220] In some embodiments, reference Figure 8-14 The vacuum module 4 may include a vacuum component. The vacuum component is configured as a vacuum pump 41.

[0221] The vacuum pump 41 may be disposed inside the drawer 21. The vacuum pump 41 includes a first air inlet and a first air outlet. The first air inlet is connected to the vacuum connector 313. The first air outlet is used to discharge the extracted air.

[0222] The first air inlet of the vacuum pump 41 can be connected to the vacuum connector 313. The first air inlet of the vacuum pump 41 can be connected to the frying chamber 30 through the vacuum connector 313. When the vacuum pump 41 is running, the vacuum pump 41 can evacuate the inside of the frying chamber 30 through the vacuum connector 313.

[0223] In some embodiments, referring to FIG13 , the vacuum module 4 may include an exhaust pipe 411. The first gas outlet of the vacuum pump 41 may be in communication with the exhaust pipe 411. When the vacuum pump 41 is running, the vacuum pump 41 may discharge the extracted gas through the exhaust pipe 411.

[0224] In some embodiments, one end of the exhaust pipe 411 may be connected to the first air outlet of the vacuum pump 41. The other end of the exhaust pipe 411 may extend outside the drawer 21. The end of the exhaust pipe 411 away from the vacuum pump 41 may be connected to the outside of the drawer 21. When the vacuum pump 41 is running, the vacuum pump 41 can discharge the extracted gas to the outside of the drawer 21 through the exhaust pipe 411.

[0225] In some embodiments, reference Fig.13 One end of the exhaust pipe 411 may be connected to the first air outlet of the vacuum pump 41. The other end of the drain pipe 411 may be connected to the water storage box of the drain module, so as to directly discharge the extracted air into the water storage box, thereby preventing the extracted air from being too humid, which may cause excessive humidity in the space where the internal components of the cooking device are located, resulting in condensed water, and bacteria breeding if not cleaned for a long time.

[0226] During the frying or cooking process, the moisture in the food will precipitate, causing the water vapor content in the gas extracted by the vacuum component to be too high, and condensation treatment is required.

[0227] In some embodiments, reference Fig.14 , 18-19, the vacuum module includes a condensation component 45. A condensation channel is formed inside the condensation component 45. The gas entering the channel can be condensed in the condensation channel. The condensation component 45 can be arranged inside the drawer 21.

[0228] 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 connected to the first air inlet. The vacuum assembly can allow the gas in the frying cavity 30 to enter the condensation channel through the vacuum joint 313 and the third air inlet 451 for condensation, and then be drawn out through the third air outlet 452 and the first air inlet.

[0229] In some embodiments, reference Fig.11 The vacuum pumping module further includes an air cooling component 42, which is used to improve the condensation capacity of the vacuum frying system.

[0230] Reference Fig.23 The air cooling component 42 includes a heat dissipation component 421. A heat dissipation channel 4211 is formed in the heat dissipation component 421 for guiding and controlling the airflow, thereby achieving 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 part that needs to be cooled to the external environment.

[0231] The heat dissipation channel 4211 has a fourth air inlet 4212 and a fourth air outlet 4213 outside thereof, which are connected to the heat dissipation channel 4211. Both interfaces are designed to connect to the heat dissipation channel 4211, and they are located outside the heat dissipation channel 4211 and are connected to each other.

[0232] The fourth air inlet 4212 is connected to the vacuum joint 313. This means that it can use external suction force to introduce the gas in the frying chamber 30 into the heat dissipation channel 4211. This design helps to enhance the airflow intensity and further improve the heat dissipation efficiency. The fourth air outlet 4213 is connected to the third air inlet 451. A continuous airflow circulation path is formed, so that the air after heat dissipation can be smoothly discharged out of the system.

[0233] In order to further enhance the working performance of the air cooling component 42, the air cooling component 42 includes an air cooling fan 42. The air cooling fan 42 is arranged on one side of the heat dissipation component 421. Its main function is to promote the flow of air in the heat dissipation duct. By generating an additional air pressure difference, the air cooling fan 42 can more efficiently remove the heat in the heat dissipation duct, thereby significantly improving the overall cooling effect of the system. Especially in the case of dealing with high heat load or requiring rapid cooling, the role of the air cooling fan 42 is particularly obvious. It can effectively improve the condensation efficiency of the extracted gas and ensure that the equipment can operate stably within a safe temperature range.

[0234] In some embodiments, reference Fig.11 The vacuum module includes 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 tub 3. A condensation cavity (not shown in the figure) can be formed inside the condenser 4342. The outside of the condenser 4342 can have a first interface 431 and a second interface 422 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.

[0235] In some embodiments, reference Figure 8 A condenser tube (not shown) may be provided in the condensation chamber. An external water source may enter the condenser tube to condense the air in the condensation chamber, cool the condenser 4342, and improve the condensation efficiency of the condenser 4342.

[0236] In some embodiments, a first water inlet pipe 4336 and a first water outlet pipe 434 may be provided outside the condenser 4342. One end of the condenser pipe 423 may extend out of the condenser 4342 and be connected to the first water inlet pipe 4336, so that one end of the condenser 4342 may be connected to the water purification box through the first water inlet pipe 4336. The other end of the condenser pipe 423 may 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 may be connected to the water purification box through the first water outlet pipe 434.

[0237] Therefore, the water in the water purification box can enter the condenser 423 through the first water inlet pipe 4336, condense the air in the condensation chamber, and then return to the water purification box through the first water outlet pipe 434, thereby forming a condensed water circulation between the condenser 423 and the water purification box.

[0238] The water circuit of the condenser 43 uses the cold purified water in the water storage box to cool the condenser 43, and the circulating condensing water pump drives the water circulation of the water storage box continuously or intermittently.

[0239] When the vacuum pump 41 is running, the vacuum pump 41 can evacuate the frying chamber 30 through the vacuum joint 313 and the condensation chamber, so that the gas in the frying chamber 30 can enter the condensation chamber through the vacuum joint 313 and the first interface 431 to condense, and then be discharged through the vacuum pump 41, which can improve the condensation performance of the vacuum pump 41 during vacuuming, which is beneficial to improving the vacuum degree of the frying barrel 3.

[0240] In the technical solution of some embodiments, one of the condensation component 45, the condenser 43 and the air cooling component 42 or a combination thereof can be selected to perform the condensation work.

[0241] Reference Figure 8 , 1113, it is explained that the vacuum component extracts gas and passes through the air cooling component 42, the condenser 43 and the condensation component 45 in sequence. Of course, the above three components can be combined in other ways. For example, the positions of the condenser 43 and the air cooling component 42 can be adjusted.

[0242] Reference Fig.11 The condenser 4342 can be arranged at one side of the frying tub 3. The condensation assembly 45 is arranged below the condenser 43 to receive the condensed water from the condensation channel.

[0243] The vacuum connector 313 is connected to the fourth air inlet 4212 of the air cooling component 42, the fourth air outlet 4213 is connected to the first connector of the condenser 43, the second connector is connected to the third air inlet 451 of the condensing component 45, the third air outlet 452 is connected to the first air inlet of the vacuum component, and the first air outlet is connected to the water storage box.

[0244] Based on the above, refer to Fig.11 , 12 The red arrow and Fig.13 As indicated by the blue arrow, the gas extracted from the frying chamber 30 is extracted through the vacuum assembly, enters the air cooling assembly 42, the condenser 43, and the condensation assembly 45 in sequence for condensation, and is then discharged into the water storage box through the first air outlet.

[0245] The reason for discharging the extracted air to the water storage box is to prevent the extracted air from still being highly humid, and it is provided for the safety of the entire components.

[0246] Of course, in some embodiments, it can also be connected to the outside air through the first air outlet.

[0247] The condensation system of the cooking device of the present application adopts a combination of air cooling and water cooling to condense the vacuum system during the cooking process.

[0248] The pipeline A connected to the frying drum 3 for vacuuming is connected to the oil storage box 76, and the oil storage box 76 is connected to the pipeline B and the fourth air inlet of the air cooling component 42. After the hot steam passes through the air cooling component 42, it passes through the pipeline C from the fourth air outlet of the air cooling component 42 to the first joint (air inlet) of the condenser 43; the second joint (air outlet) of the condenser 43 is connected to the condensation component 45 through the pipeline D. The third air outlet 452 of the condensation component 45 is connected to the vacuum component through the pipeline E.

[0249] The third air inlet 451 and the third air outlet 452 of the condensation component 45 are connected in a partitioned manner to increase the exhaust path and achieve better condensation and deposition of condensed water in the condensation water tank.

[0250] In some embodiments, the third air outlet 452 is connected to the first air inlet of the vacuum pump. The first air inlet of the vacuum pump is connected to the top area of ​​the condensation assembly 45. The vacuum pump can extract the gas in the condensation assembly 45 through the third air outlet 452, and then extract the gas inside the frying cavity 30 through the third air inlet 451, the condensation cavity, and the vacuum joint 313, so that the gas in the frying cavity 30 can enter the condensation cavity through the first joint to condense, and enter the condensation assembly 45 through the second interface for secondary condensation. Finally, it is discharged through the third air outlet 452 and the vacuum pump.

[0251] In some embodiments, reference Fig.14 The condensation assembly 45 further includes a first drain port 453. The first drain port 453 is used to drain the condensed water in the condensation assembly 45.

[0252] In some embodiments, reference Figure 18-19 The third air inlet 451 and the third air outlet 452 are arranged on both sides of the condensation channel along the length direction.

[0253] A flow guide component 454 is provided on the inner side wall of the condensation channel along the width direction. The flow guide component 454 extends from one inner side wall of the condensation channel toward the other inner side wall of the condensation channel.

[0254] By arranging a bending structure in the condensation channel, the path of the condensation channel is increased and the condensation effect is improved.

[0255] Reference Fig.19 After the gas enters the condensation component 45, it flows along the path of the red arrow, making full use of the condensation channel of the condensation component 45 for heat dissipation and condensation.

[0256] In some embodiments, the bottom surface of the condensation channel is inclined from the third air inlet 451 to the first drain outlet 453 .

[0257] Reference Fig.19 The condensed water condensed in the middle of the condensation assembly 45 is inclined from the third air inlet 451 to the first drain outlet 453, and is inclined from the third air outlet 452 to the first drain outlet 453. The first drain outlet 453 is set as the lowest point, so that the condensed water will gather at the first drain.

[0258] In this way, the entire condensed water will flow to the lowest point of the entire ground, that is, the first drain outlet 453; in order to reduce the amount of residual water in the condensation component 45 as much as possible, a sinkhole design is adopted at the bottom.

[0259] Reference Fig.13 , 14As shown, in some embodiments, the vacuum frying system may include a drainage module 8. The drainage module 8 may be in communication with the condensation assembly 45. The drainage module 8 may be used to drain the interior of the condensation assembly 45 and discharge the condensed water in the condensation assembly 45.

[0260] In some embodiments, the drainage module 8 may include a drainage channel 6281. One end of the drainage channel 6281 may be in communication with a bottom area in the condensation assembly 45. Condensed water in the condensation assembly 45 may be discharged through the drainage channel 6281.

[0261] In some embodiments, a first drain port 453 may be protruding from the top of the condensation assembly 45. The end of the drainage channel 6281 away from the drainage box 82 may be connected to the bottom area of ​​the condensation assembly 45 through the first drain port 453. The condensed water in the condensation assembly 45 may be drained into the drainage box 82 through the first drain port 453 and the drainage channel 6281.

[0262] In some embodiments, the drainage module 8 may include a drainage box 82. The other end of the drainage channel 6281 may be connected to the interior of the drainage box 82. The condensed water in the condensation assembly 45 may be discharged to the interior of the drainage box 82 through the drainage channel 6281.

[0263] In some embodiments, the drainage module 8 may include a drainage pump 63. The drainage pump 63 may be disposed on the drainage channel 6281. When the drainage pump 63 is turned on, the drainage pump 63 can extract water in the condensation assembly 45 through the drainage channel 6281, and discharge the extracted water into the drainage box 82 through the drainage channel 6281.

[0264] In some embodiments, the drainage module 8 may include a drainage switch valve 64. The drainage switch valve 64 may be disposed on the drainage channel 6281. The drainage switch valve 64 may be disposed in a pipeline between the condensation component 45 and the drainage water pump 63. The drainage switch valve 64 may be used to open and close the drainage channel 6281.

[0265] When the drain switch valve 64 closes the drain channel 6281 , the interior of the condensation assembly 45 can be sealed and isolated from the drain box 82 , so that the interior of the condensation assembly 45 can be evacuated.

[0266] When the drain switch valve 64 opens the drain channel 6281, the interior of the condensation assembly 45 can communicate with the interior of the drain box 82. The drain water pump 63 can extract water from the condensation assembly 45 and drain the extracted water into the drain box 82.

[0267] Reference Fig.21 As shown, in some embodiments, a water inlet head 821 extending upward may be protrudingly provided inside the drainage box 82. The top port of the water inlet head 821 may be connected to the top area inside the drainage box 82.

[0268] When the drain switch valve 64 opens the drain channel 6281 and the drain pump 63 starts to run, the drain pump 63 can extract water in the condensation component 45 and discharge it into the drain box 82 through the drain channel 6281 and the water inlet head 821.

[0269] Reference Fig.21 As shown, in some embodiments, the drainage module 8 may include a second storage box 85. The second storage box 85 may be disposed inside the drawer 21. The second storage box 85 may be disposed on one side of the barrel body 31. A water inlet connector 851 may be disposed in the second storage box 85. One end of the drainage channel 6281 away from the condensation assembly 45 may be connected to the water inlet connector 851. The drainage box 82 may be detachably disposed in the second storage box 85.

[0270] When the drainage box 82 is disposed in the second storage box 85 , the water inlet connector 851 can be connected to the water inlet head 821 so that the drainage channel 6281 is connected to the water inlet head 821 , thereby draining the water in the condensation assembly 45 into the drainage box 82 .

[0271] In some embodiments, a water level detection component 823 may be provided on the inner wall of the drainage box 82. The water level detection component 823 may be used to detect the water level inside the drainage box 82. The water level detection component 823 may be electrically connected to the controller 61. When it is detected that the water level inside the drainage box 82 reaches a preset height, the user may be reminded to take the drainage box 82 out of the second storage box 85, and the user may be reminded to clean the drainage box 82 in time.

[0272] In some embodiments, referring to 16 and 17 , the cooking device includes a pressure relief module 8 for relieving the pressure of the frying cavity 30 .

[0273] The pressure relief module further includes a pressure relief channel 81. One end of the pressure relief channel 81 is connected to the vacuum connector 313. The other end of the pressure relief channel 81 is connected to the air, so that the frying chamber 30 can be directly connected to the air.

[0274] 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 air; when the pressure is released, the air passes through the oil box 76 and enters the frying chamber 30 .

[0275] The gas passes through the oil box 76 as a transition from the frying chamber 30, and then finally enters the frying chamber 30 along the pressure relief channel 81. Such a design not only ensures the need for safe pressure relief, but also takes into account the problem of preventing high-temperature grease from directly spraying out and causing safety hazards.

[0276] In some embodiments, the cooking device further comprises a pressure relief switch 82. The pressure relief switch 82 is mounted on the pressure relief channel 81. The pressure relief switch 82 is used to control whether the frying chamber 30 is connected to the air. In some embodiments, the pressure relief switch 82 is configured as a valve.

[0277] During the cooking process, the vacuum component remains in working state, and a large amount of condensed water vapor will remain in the pipeline. If the air pressure in the pipeline is directly released, the water vapor will be blown back to the frying barrel 3, causing the food in the barrel to become damp.

[0278] In the above scheme, the frying barrel 3 is connected to the oil box 76, and the oil box 76 is connected to the air, and a pressure relief switch 82 is provided on the connecting pipeline. When the frying barrel 3 needs to be depressurized, the air directly enters the frying barrel 3 for depressurization. The airflow from the vacuum pump is prevented from entering the frying barrel 3, which effectively solves the problem of moisture in the food in the frying barrel 3 after cooking.

[0279] In some embodiments, during the cooking process, the vacuum module 4 is controlled to evacuate the frying chamber 30. After the cooking is completed, the oil control switch 74 is first controlled to be turned on, so that the oil in the frying chamber 30 flows into the oil box 76 through the first oil drain port 311 and the second oil inlet for de-oiling, and then the pressure relief switch is controlled to relieve the pressure in the frying chamber 30.

[0280] The above-mentioned deoiling process includes automatic deoiling by gravity and deoiling by centrifugal force generated by a driving module.

[0281] During the cooking process, in order to ensure that the food can be evenly heated and achieve an ideal taste and flavor, the frying chamber 30 needs to be vacuumed.

[0282] Specifically, after the food is placed in the frying chamber 30, the vacuum module 4 is started to extract the air in the chamber, thereby reducing the generation of oil smoke during frying, and also avoiding the generation of foam on the food surface due to high temperature, further improving the quality of the food.

[0283] After the cooking process is completed, the oil control switch 74 is first turned on, so that the cooking oil inside the frying chamber 30 will flow into the oil box 76 for collecting oil through the designed first oil outlet 311 and the second oil inlet, so as to carry out the subsequent de-oiling process, ensuring that there will be no excessive oil on the surface of the food, making the finished product healthier and more delicious. The last step is to turn on the pressure relief switch to slowly release the high pressure environment in the frying chamber 30, ensuring safety while also preparing for the next use.

[0284] By providing a frying barrel 3, an oil box 76 arranged below the frying barrel 3, and a vacuum component, after cooking, the oil is first discharged into the oil box 76 by its own gravity, and then the pressure is released, thereby avoiding the food from re-absorbing the oil after the pressure is released, which affects the taste of the food.

[0285] In some embodiments, the controller is configured to control the heating assembly to heat the frying cavity 30 before cooking, so that the temperature of the frying cavity 30 reaches a target preset temperature (first target preset temperature). Preheating is performed before cooking to heat the pan and reduce oil absorption by the ingredients.

[0286] In some embodiments, after the pressure is released, the drainage pump 63 is turned on, and the condensed water in the condensation assembly 45 flows into the water storage box.

[0287] The first drain port is connected to the water storage box through a drain channel, and a drain pump is provided on the drain channel. After the pressure is released, the controller automatically turns on the drain pump, so that the condensed water in the condensation assembly can flow into the water storage box quickly and smoothly. This design ensures the effective discharge of condensed water and avoids secondary pollution and equipment failure caused by the accumulation of condensed water.

[0288] Through the automatic control of the controller, the condensed water can be discharged in time to avoid excessive condensed water remaining in the condensation component. This can not only keep the inside of the equipment dry, but also effectively reduce the growth of bacteria and odor, and improve the hygiene level of the equipment.

[0289] In some embodiments, during the cooking process, the air cooling fan 42 is operated to improve the condensation effect during the cooking process.

[0290] The heat dissipation channel in the air cooling component is designed with a fourth air inlet and a fourth air outlet, the fourth air inlet is connected to the second air outlet, and the fourth air outlet is connected to the third air inlet. This design allows air to circulate in the heat dissipation channel to take away the heat generated during the cooking process, thereby effectively reducing the temperature inside the cooking device and reducing the humidity of the extracted gas.

[0291] In some embodiments, before cooking, check that the water storage box and the oil storage box 76 are in place and ensure that the remaining space therein is sufficient for use or to be emptied. Fill the water purification box with water.

[0292] Before formal cooking, it is necessary to carefully check and prepare each key component to ensure that the cooking process proceeds smoothly. First, confirm that the water storage box has been installed in place and that there is enough space inside to store the required amount of water. If it is found that there is insufficient space, some of the water should be emptied appropriately. Next, check whether the oil storage box 76 has been installed correctly, and whether the remaining space inside it is also sufficient to accommodate the waste oil that may be generated during the cooking process. Similarly, if there is not enough space, the waste oil needs to be emptied first. In addition, it is also necessary to ensure that the water purification box has been completely filled with clean water, because an adequate water source is essential to maintaining the normal operation of the cooking equipment, and it also ensures the purity of the water quality during the cooking process, so as not to affect the final taste and safety of the food. Through these meticulous preparations, the cooking efficiency and the quality of the finished product can be greatly improved.

[0293] In some embodiments, during the preheating stage, the vacuum assembly is operated to maintain a first preset vacuum level inside the frying cavity 30 .

[0294] During the preheating stage, in order to ensure the cooking effect and efficiency, the equipment will start the vacuum component. The main function of this component is to extract the air in the frying chamber 30 so that the interior reaches and maintains a preset vacuum level, namely the first preset vacuum level. Maintaining this vacuum environment has multiple benefits: first, it helps to remove excess moisture on the surface of the food, so that the food can absorb heat faster and more evenly during the subsequent frying process; second, the vacuum state can also reduce the degree of oxidation of oil and extend the service life of the oil, while also reducing the generation of oil smoke and improving the working environment in the kitchen; finally, this vacuum treatment method can also help the food better lock in nutrients, thereby improving the overall quality of the food. In short, maintaining an appropriate vacuum level during the preheating stage has an important impact on the subsequent cooking process.

[0295] In some embodiments, after preheating is completed, the vacuum component is used to release pressure for a certain period of time, and the user is reminded to add a certain amount of food.

[0296] In some embodiments, during the preheating stage, a circulating water pump is used to circulate water in the condenser pipe, the first water inlet pipe, and the second water outlet pipe to detect whether the water level in the water purification box is lower than a limit value. If it is lower than the limit value, the user is reminded to add purified water.

[0297] During the preheating stage, the system will circulate the water in the condenser pipe, the first water inlet pipe and the second water outlet pipe through the circulating water pump to maintain the condensation effect. At the same time, the device will also monitor whether the water level in the water purification box is lower than the preset limit value. If it is detected that the water level in the water purification box is lower than this limit value, the system will automatically trigger an alarm or send a notification to the user to remind them to add purified water in time to ensure the normal operation of the device, avoid the problem of poor condensation effect due to too low water level, and ensure the efficient operation of the device.

[0298] In some embodiments, during the operation of the vacuum assembly in the preheating phase, the air cooling fan 42 is operated to reduce the temperature in the heat dissipation channel 4211 .

[0299] In some embodiments, after preheating is completed, the heating assembly is controlled to heat the frying cavity 30 so that the temperature in the frying cavity 30 reaches a second target preset temperature, wherein the second target preset temperature is greater than the first target preset temperature.

[0300] During the cooking process, the heating element is turned on or off to control the frying cavity 30 to maintain the second target preset temperature.

[0301] During frying or cooking, the vacuum assembly operates and maintains a second preset vacuum degree inside the frying chamber 30. The second preset vacuum degree is less than the first preset vacuum degree, so as to achieve a better vacuum frying effect.

[0302] In some embodiments, during the cooking process, the driving module drives the net bucket to run intermittently. In some embodiments, we can control the driving module to drive the net bucket to rotate forward and reverse alternately to turn the food.

[0303] In some embodiments, during the cooking process, a circulating water pump is used to circulate water in the condenser pipe, the first water inlet pipe, and the second water outlet pipe to detect whether the water level in the water purification box is lower than a limit value. If it is lower than the limit value, the user is reminded to add purified water.

[0304] In some embodiments, during the cooking process, when the vacuum assembly is running, the air cooling fan 42 is running to reduce the temperature in the heat dissipation channel 4211.

[0305] In some embodiments, after cooking, the food in the frying cavity 30 is de-oiled and the frying cavity 30 is depressurized.

[0306] In some embodiments, after the oil control switch 74 is turned on for a certain period of time, the driving module drives the net barrel to operate to deoil the food.

[0307] During the de-oiling period, the oil control switch 74 is always in the open state.

[0308] After the oil removal is completed, the pressure relief valve is controlled to start and complete the pressure relief.

[0309] In some embodiments, after the pressure relief is completed, the switch valve connecting the water storage box and the oil storage box 76 is opened, the drainage water pump 63 is started to drain the condensed water in the condensation assembly 45 to the water storage box, and the oil drainage pump 73 is started to drain the oil in the oil box 76 to the oil storage box 76. The cooking process is completed.

[0310] In some embodiments, after the drainage and oil removal are completed, the user is prompted to pick up the food.

[0311] Reference Fig.24 , illustrating the preheating control logic of the cooking device in this application.

[0312] The heating assembly is controlled to preheat the frying chamber 30 (S101).

[0313] The vacuum assembly is controlled to evacuate the frying tub 3 to maintain the frying cavity 30 at a first vacuum degree (S102).

[0314] After the heating component preheats the frying chamber 30 for a certain period of time, the frying chamber 30 is depressurized and the user is reminded to add a certain amount of food (S103).

[0315] The circulating water pump is used to circulate water in the condenser, the first water inlet pipe and the second water outlet pipe. When the water level in the purified water box is detected to be lower than a limit value, the user is reminded to add purified water (S104).

[0316] It should be noted that if the cooking device does not use a water cooling system for condensation, step S104 is not performed.

[0317] The air cooling fan 42 is controlled to start running (S105) to take away the heat in the heat dissipation channel 4211 and improve the condensation effect.

[0318] The above steps S101-S105 are in the preheating stage of the cooking device. S101, S102, S103, S105 can be performed in parallel or in different orders. For example, S102 is performed first and then S101.

[0319] Reference Fig.24 , explaining the cooking control logic of the cooking device in this application.

[0320] After the preheating is completed, the cooking process begins, the heating component continues to heat the frying barrel 3, and the frying chamber 30 is maintained at the target temperature by starting and stopping the heating component (S201).

[0321] The vacuum assembly is controlled to evacuate the frying tub 3 to maintain the frying cavity 30 at a second vacuum degree (S202).

[0322] The driving module drives the net bucket to run intermittently or to run forward and reverse alternately (S203).

[0323] The circulating water pump is used to circulate water in the condenser, the first water inlet pipe and the second water outlet pipe. When the water level in the water purification box is detected to be lower than a limit value, the user is reminded to add purified water (S204).

[0324] The air cooling fan 42 is controlled to start running (S205) to take away the heat in the heat dissipation channel 4211 and improve the condensation effect.

[0325] The above steps S201-S205 are in the preheating stage of the cooking device. S201, S202, S203, S204, S505 can be performed in parallel or in different orders. For example, S202 is performed first and then S201.

[0326] Reference Fig.24 , describing the post-cooking control logic of the cooking device in this application.

[0327] After cooking is finished, the oil control switch 74 is turned on to allow the oil in the frying cavity 30 to flow into the oil box 76 (S301).

[0328] After the oil control switch 74 is turned on for a certain period of time, the driving module is started to drive the net barrel to rotate so as to separate the oil in the food from the food (S302).

[0329] The pressure relief switch 82 is turned on to relieve the pressure in the frying chamber 30 (S303).

[0330] The above steps are the de-oiling and pressure relief steps after frying, and the execution order of de-oiling and pressure relief cannot be adjusted to avoid the situation where the food is oiled back.

[0331] In some embodiments, the drain pump 63 is turned on to drain the condensed water in the condensation component 45 into the water storage box, and the oil drain pump 73 is turned on to drain the oil in the oil box 76 into the oil storage box 76 (S401). At the end, this is to prevent the system from depressurizing and causing the cooking oil to penetrate into the cooking ingredients, causing the ingredients to return oil.

[0332] The oil storage box 76 in the vacuum environment is used as a temporary storage space. The oil control switch 74 is turned on in the vacuum environment, so that the cooking oil in the frying barrel 3 flows to the oil storage box 76 under the influence of gravity. After a certain period of time, the whole system enters the high-speed oil removal mode. As the net barrel rotates, not only the oil on the food is shaken off, but also the rapid discharge of the oil in the frying barrel 3 is accelerated.

[0333] The above-mentioned scheme of relying on gravity to drop oil has low cost and reliable structure, but the effective space of the oil storage box 76 must be below the bottom surface of the frying barrel 3.

[0334] When cooking and degreasing are finished, the system will release pressure. After the pressure is released, the drainage pump 63 and the oil drain pump 73 are turned on, and then the oil is pumped into the oil box 76 through the oil drain pump 73 connected to the oil storage box 76, and the drainage pump 63 connected to the condensation component 45 is pumped into the water storage box, so that the food is depressurized in an oil-free state, and the oil drain system is more reliable and has lower costs.

[0335] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
