[0039] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, the present application provides an oven, including an equipment body 200 and a cooking accessory 100, wherein the cooking accessory 100 is detachably arranged in an inner pot 210 of the equipment body 200; the cooking accessory 100 includes a driving component, an inner shell 10 and an outer shell 20 which are nested with each other, the driving component is used to drive the inner shell 10 and the outer shell 20 to open and close independently, the inner shell 10 has a containing cavity 40 inside, a smoke sensor 114 which is electrically connected to a control chip of the equipment body 200 is arranged in the containing cavity 40, and an interlayer 50 for accommodating smoking materials is provided between the inner shell 10 and the outer shell 20; a vacuum pumping component 220 which is connected to the containing cavity 40 is also arranged in the equipment body 200.

[0040] By arranging the cooking accessories 100 in the inner pot 210 to accommodate the food to be cooked, the air in the accommodating cavity 40 can be discharged through the vacuum assembly 220 after the inner shell 10 is closed, thereby preventing the food in the cooking accessories 100 from being oxidized, thereby achieving the effect of maintaining the freshness of the food. In conjunction with the driving assembly electrically connected to the control chip, the shell can be automatically opened at the scheduled time, thereby achieving the effect of preserving the scheduled cooked food.

[0041] After placing the smoking material in the interlayer 50, the smoke concentration in the accommodating cavity 40 is detected in real time by the smoke sensor, and the opening angle of the inner shell 10 is controlled by the driving component, so as to achieve precise control of the smoking effects of different flavors of food; after the smoking is completed, the smoke in the cooking accessory 100 can be discharged through the vacuum component 220 to ensure that no smoke smell will remain in the inner pot 210, thereby improving the user experience.

[0042] The specific working principle is as follows: the user sets the required smoke concentration in advance, closes the outer shell 20, opens the inner shell 10, and the lower heating tube at the bottom of the inner liner 210 is started to heat the smoke material placed at the bottom of the interlayer 50 and generate smoke;

[0043] The smoke sensor 114 disposed in the accommodating chamber 40 detects the smoke concentration in the accommodating chamber 40 in real time. The control chip calculates the difference between the set smoke concentration and the detected real-time smoke concentration, and controls the opening angle of the inner shell 10 according to the difference between the two.

[0044] Specifically, when the real-time concentration is greater than the set concentration, the greater the difference, the smaller the opening angle of the inner shell 10 is, so as to reduce the real-time smoke concentration in the accommodating chamber 40; conversely, when the real-time concentration is less than the set concentration, the greater the difference, the larger the opening angle of the inner shell 10 is, so as to increase the real-time smoke concentration in the accommodating chamber 40; thereby maintaining the real-time smoke concentration in the accommodating chamber 40 around the set concentration, thereby achieving precise control of the smoking effects of different flavors.

[0045] In addition, the cooking accessory 100 can be detachably arranged in the inner pot 210, which can increase the applicable scenarios of the oven and increase its versatility. Specifically, after the cooking accessory 100 is removed, the inner pot 210 has a larger accommodating space, and the cooking equipment can perform normal cooking operations. When scheduled cooking or smoking and grilling is required, by placing the food to be cooked in the cooking accessory 100, the cooking needs of food preservation or smoking and grilling can be met.

[0046] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, a temperature sensor 113 electrically connected to the control chip is further disposed in the accommodating cavity 40; the outer shell 20 is made of opaque material, and the inner shell 10 is made of highly translucent material.

[0047] Since the inner shell 10 is made of a highly light-transmitting material, after the inner shell 10 is kept closed and the accommodating chamber 40 is evacuated, the radiant heat from the infrared radiation heating tube on the top of the inner pot 210 can still penetrate the inner shell 10 to heat the food in the accommodating chamber 40;

[0048] By cooperating with the temperature sensor 113 to detect the temperature in the accommodating cavity 40 in real time and changing the opening angle of the outer shell 20 of the opaque material, the temperature of the food can be precisely controlled to meet the needs of anaerobic baking or low-oxygen fermentation.

[0049] The specific working principle is as follows: the user sets the heating temperature in advance, opens the outer shell 20, closes the inner shell 10, and starts the infrared radiation heating tube on the top of the inner liner 210 to heat the inside of the accommodating cavity 40;

[0050] The temperature sensor 113 disposed in the accommodating chamber 40 detects the real-time temperature in the accommodating chamber 40. The control chip calculates the difference between the user-set temperature and the detected real-time temperature, and controls the opening angle of the inner shell 10 according to the difference between the two.

[0051] Specifically, when the real-time temperature is greater than the set temperature, the greater the difference, the smaller the opening angle of the outer shell 20 is, so as to lower the real-time temperature in the accommodating cavity 40; conversely, when the real-time temperature is lower than the set temperature, the greater the difference, the larger the opening angle of the inner shell 10 is, so as to increase the real-time temperature in the accommodating cavity 40; thereby maintaining the real-time temperature in the accommodating cavity 40 around the set temperature, thereby achieving precise control of the cooking temperature in an anaerobic or low-oxygen environment.

[0052] Please combine Figure 2 , Figure 3 as well as Figure 4 As shown, in some embodiments, a refrigeration assembly 230 communicating with the interlayer 50 is further disposed in the device body 200 .

[0053] First, by setting up the refrigeration component 230, when cooking is scheduled, not only can the air in the accommodating cavity 40 be extracted by relying on the vacuum component 220, but cold air can also be passed into the interlayer 50 through the refrigeration component 230, so that the inner shell 10 and the internal accommodating cavity 40 can be quickly cooled, achieving the dual preservation effect of vacuum refrigeration.

[0054] Secondly, during the above-mentioned low-temperature anaerobic baking and fermentation process, if the outer shell 20 is completely closed, but the temperature inside the accommodating chamber 40 is still too high, by starting the refrigeration component 230, cold air can be introduced into the interlayer 50 to absorb the heat of the inner shell 10, thereby maintaining the temperature inside the accommodating chamber 40 at a precise low temperature state.

[0055] Finally, the refrigeration component 230 can also cool down the food after cooking, so that the user can eat it immediately after cooking. In conjunction with the temperature sensor 113, it can also achieve precise control of the food temperature to improve the user experience.

[0056] The specific working principle is as follows: the user sets the food serving temperature in advance, and when the food placed in the accommodating cavity 40 is finished steaming, the outer shell 20 is closed, the inner shell 10 is opened, and the refrigeration component 230 is started to cool the interlayer 50 and the interior of the accommodating cavity 40;

[0057] The temperature sensor 113 disposed in the accommodating cavity 40 detects the temperature of the food in real time. The control chip calculates the difference between the food edible temperature set by the user and the detected real-time temperature of the food, and controls the opening angle of the inner shell 10 according to the difference between the two.

[0058] Specifically, the temperature difference is proportional to the opening angle of the inner shell 10. When the real-time temperature is greater than the set temperature, the greater the difference, the greater the opening angle of the inner shell 10, and the better the cooling effect on the food; as the real-time temperature decreases, the opening angle of the inner shell 10 gradually decreases until the real-time temperature drops to equal the set temperature, the inner shell 10 is completely closed, and the accommodating cavity 40 is in a completely sealed state;

[0059] After the real-time temperature drops to the set temperature, the vacuum assembly 220 can be activated to extract the air in the accommodating cavity 40 to prevent the food temperature from continuing to drop.

[0063] Specifically, the vacuum assembly 220 includes a vacuum tube 221 and a vacuum pump 222, and the refrigeration assembly 230 includes a refrigeration tube 231 and a refrigerator 232. The refrigerator 232 and the vacuum pump 222 are both arranged on the top of the inner liner 210. The vacuum assembly 220 is connected to the installation groove 211 through the vacuum tube 221, and the refrigerator 232 is connected to the interlayer 50 through the refrigeration tube 231.
