Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, and in particular to a cooking apparatus. Background Technology

[0002] With the improvement of living standards, cooking appliances have gradually become indispensable electrical products in home life. Cooking appliances, such as ovens, steam ovens, or steam ovens, are cooking machines that contain food in a closed space and heat and cook it.

[0003] In cooking appliances such as ovens, steam ovens, or steam ovens, the interior typically consists of a cabinet and an inner liner within the cabinet. The inner liner forms a cooking cavity where food is cooked at high temperatures.

[0004] Existing cooking appliances such as ovens, steamers, or steam ovens lack low-temperature frying capabilities. While some appliances offer high-temperature frying, their efficiency is low and they can easily lead to nutritional deficiencies in food. Therefore, it is necessary to research a vacuum low-temperature frying system for use in cooking appliances to achieve vacuum low-temperature frying functionality and improve the sealing performance of the frying pan. Summary of the Invention

[0005] The purpose of this invention is to provide a cooking device to realize the vacuum low-temperature frying function of the cooking device.

[0006] Another objective of this invention is to provide a cooking apparatus to improve the sealing performance of a vacuum frying pan.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] According to one aspect of the present invention, a cooking apparatus is provided, comprising: a housing forming an outer shell of the cooking apparatus; an inner liner disposed within the housing, the inner liner having a cooking cavity formed therein; a frying drum having a frying cavity formed therein; and a vacuum module connected to the frying cavity, the vacuum module being used to vacuum the frying cavity; wherein the frying drum includes a drum body, a drum lid, an elastic sealing element, and a rotating seat; the frying cavity is formed inside the drum body, and the top of the drum body has an opening communicating with the frying cavity. The bucket lid is rotatably mounted on the top surface of the bucket body, and is used to open and close the top opening of the bucket body. An elastic seal is located at the top opening of the bucket body. When the bucket lid closes the top opening of the bucket body, the elastic seal seals the gap between the bucket lid and the top opening of the bucket body. A first shaft hole is provided on the rotating seat. The rotating shaft of the bucket lid is movably arranged within the first shaft hole. When a vacuum is drawn inside the frying chamber, the bucket lid can compress the elastic seal downwards, causing the rotating shaft of the bucket lid to move downwards along the first shaft hole.

[0009] In some embodiments of this application, the longitudinal section of the first shaft hole is an elongated hole, which extends in the vertical direction; before the frying chamber is evacuated, the rotating shaft of the bucket lid can be arranged in the upper region of the elongated hole; when the frying chamber is evacuated, the rotating shaft of the bucket lid can move downward along the elongated hole.

[0010] In some embodiments of this application, the frying bucket includes a lock body located on the side of the bucket body away from the rotating seat; the end of the bucket lid away from the rotating seat is provided with a downwardly extending locking tongue; when the bucket lid closes the top opening of the bucket body, the lock body is located below the locking tongue, and the locking tongue can extend downward and engage with the lock body.

[0011] In some embodiments of this application, the top of the lock body is provided with a first clamping arm and a second clamping arm arranged at intervals opposite to each other, and a locking groove is formed between the first clamping arm and the second clamping arm; when the lid closes the top opening of the barrel body, the locking tongue can extend downward into the locking groove, engage and clamp between the first clamping arm and the second clamping arm; when the frying chamber is evacuated, the locking tongue can gradually extend into the locking groove, and the first clamping arm and the second clamping arm can gradually clamp the locking tongue.

[0012] In some embodiments of this application, the frying bucket includes a connecting seat, which is disposed at one end of the bucket lid near the rotating seat; the frying bucket includes a rotating shaft, which serves as the rotating shaft of the bucket lid; the rotating shaft is connected to the connecting seat and is movably inserted into the first shaft hole of the rotating seat; the connecting seat is rotatably connected to the rotating seat through the rotating shaft.

[0013] In some embodiments of this application, a slot is provided at one end of the bucket lid near the rotating seat; the connecting seat is detachably inserted into the slot.

[0014] In some embodiments of this application, a boss is provided on the top surface of the rotating seat, and the first shaft hole is opened in the boss; a lug is provided on the end of the connecting seat away from the bucket lid, and a second shaft hole is opened in the lug; the rotating shaft is movably inserted into the first shaft hole and fixed in the second shaft hole; the lug is rotatably connected to the boss through the rotating shaft.

[0015] In some embodiments of this application, the frying bucket includes an inner cover, which is detachably disposed on the bottom surface of the bucket lid; when the bucket lid is closed, the inner cover can cover the top opening of the bucket body, and the peripheral edge of the inner cover can seal against the elastic sealing element.

[0016] In some embodiments of this application, the cooking device includes a drawer box and a drawer, the drawer being removably disposed within the drawer box and the drawer box being disposed outside the inner liner; the frying drum is disposed within the drawer.

[0017] In some embodiments of this application, a top cover is provided on the top surface of the drawer, and the top cover is provided over the top opening of the drawer; the rotating seat and the lock body are respectively fixed on the top cover and are respectively provided on opposite sides of the barrel body.

[0018] The embodiments of the present invention have the following advantages and positive effects:

[0019] The cooking apparatus of this invention includes a frying drum and a vacuum module. The frying drum has a frying chamber, and the vacuum module is used to vacuum the frying chamber, thereby achieving the function of vacuum low-temperature frying in the frying chamber.

[0020] The frying chamber is opened and closed by a rotatable lid that is placed on the top surface of the container. An elastic seal is used to seal the gap between the lid and the top opening of the container, thus achieving a seal for the frying chamber.

[0021] The lid is movably positioned within the first shaft hole of the rotating seat via its rotating shaft. When a vacuum is drawn into the frying chamber, the lid compresses the elastic seal downwards, causing the rotating shaft of the lid to move downwards along the first shaft hole. This allows the lid to move downwards as a whole, sealing and pressing the top opening of the barrel, thereby improving the sealing performance of the frying chamber and enhancing the vacuum level within it.

Figure 7 yes Figure 6 A schematic diagram of the internal structure of the middle drawer 21. Figure 8 yes Figure 7 A structural diagram from another perspective.

[0102] Please see Figures 5 to 8 As shown, in some embodiments, the cooking apparatus may include a vacuum frying system. The vacuum frying system can be used to vacuum-fry food at low temperatures. Compared to conventional frying, the oil temperature during vacuum low-temperature frying is typically controlled between 80°C and 100°C, far lower than the 160°C to 230°C of conventional frying. This low-temperature treatment effectively reduces the destruction of heat-sensitive nutrients in food, such as vitamins and antioxidants, thereby better preserving the nutritional value of the food.

[0103] It should be noted that in a vacuum environment, the boiling point of water in food decreases, allowing it to evaporate rapidly and significantly shortening the drying time. This not only improves production efficiency but also reduces potential adverse changes to food caused by prolonged high-temperature processing, resulting in a crisp and delicious texture.

[0104] Because frying occurs under vacuum, the moisture in the food can be directly converted into steam and escape, rather than absorbing large amounts of oil. Therefore, the oil content of vacuum-fried foods can be significantly lower than that of traditionally fried foods, generally between 10% and 20%, contributing to a healthier dietary option.

[0105] Low-temperature processing and rapid dehydration help preserve the original color and flavor of food. Flavor and aroma components in food are less likely to be lost under vacuum conditions; instead, they tend to concentrate due to reduced moisture, resulting in a crispier texture and richer flavor.

[0106] Vacuum frying, due to its extremely low moisture content and anaerobic environment, effectively inhibits microbial growth, extends the shelf life of food, and facilitates storage and transportation.

[0107] This technology is applicable to a variety of food ingredients, 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.

[0108] Please see Figures 2 to 8As shown, in some embodiments, the vacuum frying system may be located inside drawer 21. It should be noted that in other embodiments, the vacuum frying system may also be located inside the housing 1, or in other areas outside the inner liner 11.

[0109] Please see Figures 5 to 8 As shown, in some embodiments, the vacuum frying system may include a frying tank 3. A frying cavity 30 may be formed inside the frying tank 3. The frying cavity 30 may be used to hold oil, which, when heated, can fry the food within the frying cavity 30.

[0110] In some embodiments, the air frying system may include a vacuum module 4. The vacuum module 4 may be connected to the frying chamber 30 inside the frying tank 3. The vacuum module 4 is used to create a vacuum inside the frying chamber 30. Therefore, food can be vacuum-fried at low temperature inside the frying chamber 30.

[0111] In some embodiments, the outer wall of the frying drum 3 may be provided with a vacuum connector 313 communicating with the frying chamber 30. The vacuum module 4 may be connected to the vacuum connector 313. The vacuum module 4 may extract air from the frying chamber 30 through the vacuum connector 313, thereby achieving vacuuming of the frying chamber 30.

[0113] Please see Figures 9 to 11 As shown, in some embodiments, the frying tub 3 may include a tub body 31. A frying cavity 30 may be formed inside the tub body 31. The top of the tub body 31 may have an opening communicating with the frying cavity 30.

[0114] In some embodiments, the vacuum connector 313 may protrude from the outer wall of the barrel 31. The vacuum connector 313 may be located in the top region of the outer wall of the barrel 31. The vacuum connector 313 may be arranged near the top opening of the barrel 31.

[0115] Please see Figures 9 to 11 As shown, in some embodiments, the frying tub 3 may include a lid 32. The lid 32 can be movably disposed on the top surface of the tub body 31. The lid 32 can be used for the top opening of the tub body 31, and thus for opening and closing the frying chamber 30.

[0116] In some embodiments, the lid 32 may be rotatably mounted on the top surface of the barrel body 31. The lid 32 may rotate relative to the barrel body 31, thereby opening or closing the frying chamber 30.

[0117] It should be noted that in other embodiments, the lid 32 may also be detachably placed over the top opening of the barrel body 31.
