Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to a cooking device. Background Art

[0002] An air fryer is a modern kitchen appliance that uses high-speed air circulation technology to cook food to a similar effect as deep-frying, but without the use of large amounts of oil. This cooking method is not only healthy, but also environmentally friendly, time-saving, versatile and easy to operate.

[0003] The working principle of the air fryer is to form hot air by heating the heat pipe inside the machine at high temperature, and then use a fan to blow the hot air into the pot to heat the ingredients. In the closed space, the hot air circulates and uses the fat of the ingredients to fry the food, dehydrating the food and making the surface golden and crispy, achieving the frying effect.

[0004] The patent for an air fryer that is conducive to outer shell cooling disclosed in application number CN2019222446751 includes a body with a cooking cavity, a pot body that can enter and exit the cooking cavity, and a heating element that can deliver high-temperature gas to the cooking cavity, wherein the body includes an outer shell, an upper cover arranged on top of the outer shell, an inner pot installed in the outer shell, and an air guide hood installed in the upper cover, a heat insulation hood is installed in the air guide hood, and an annular guide wall is protruding downward from the inner wall of the air guide hood, and a guide cavity is formed between the guide wall and the top surface of the heat insulation hood. The air fryer can improve the efficiency of air circulation and the cooling effect, which is conducive to outer shell cooling. A structure is disclosed in which cold air is taken in from the bottom of the device and then discharged from the upper part of the device; in the patent, the cold air at the bottom reaches the cold air cavity at the top, and the air outlet of the cold air cavity is integrated with the air outlet of the cooking cavity, thereby achieving the effect of heat dissipation of the entire device;

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-4 The utility model provides a technical solution: a cooking device, preferably but not limited to an air fryer, a hot air oven, a multi-function cooking pot, an electric oven and the like, which heats and cooks food by circulating hot air.

[0033] A cooking device includes a shell 1 and a base 2 arranged at the bottom of the shell 1; wherein a motor frame 10, an air guide plate 6, a heat circulation assembly and an inner pot 3 are arranged in the shell 1, and the air guide plate 6 is arranged above the inner pot 3 to form a cooking cavity, in which a pot body assembly is placed for frying and grilling. The motor frame 10 is arranged above the air guide plate 6, and the heat circulation assembly is located above the pot body assembly. The shell 1 is also provided with an exhaust port 18 for discharging airflow in the machine body, and the cooking cavity can be opened. For example, in this embodiment, openings are correspondingly arranged on one side of the shell 1 and the inner pot 3, and the pot body assembly enters and exits the cooking cavity through the opening to form a drawer-type. The pot body assembly includes a door panel member that seals the opening and a food container connected to the door panel member.

[0034] The heat circulation assembly includes a driving motor 9, a first fan blade 13 and a heating element 8. The motor frame 10 and the upper part of the housing 1 form a housing cavity, in which the driving motor 9, a circuit board and other components are mainly placed. The motor shaft of the driving motor 9 passes through the motor frame 10 and the air guide plate 6 and is connected to the first fan blade 7. A cold air cavity is formed between the motor frame 10 and the air guide plate 6; a second fan blade 13 is arranged in the cold air cavity, and the driving motor 9 drives the second fan blade 13 to rotate in the cold air cavity.

[0035] A surrounding plate 142 is arranged around the outer periphery of the second fan blade 13. The surrounding plate 142 is circular and surrounds the outer periphery of the second fan blade 13 and is arranged concentrically with the second fan blade 13. The two ends of the surrounding plate 142 are respectively abutted against the motor frame 10 and the air guide plate 6. The surrounding plate 142, the air guide plate 6 and the motor frame 10 surround and form an air guide cavity 14.

[0036] Specifically, the enclosure 142 can be disposed on the bottom surface of the motor frame 10 or the top surface of the air guide plate 6 , and then abutted against the remaining motor frame 10 or the air guide plate 6 .

[0037] The air guide cavity 14 is connected with an air guide channel 141 and an exhaust channel. The path of the air guide channel 141 needs to be tangent to the contour of the rotation trajectory of the second fan blade 13, and the design should be smooth as much as possible to reduce bending. This design allows the cold air to quickly reach the place where the temperature is too high, reduces the loss of cold air when it moves in the air guide channel 141, and reduces the possibility of cold air conflict in the air guide channel 141. As an alternative, the air guide channel 141 can also adopt but not limited to structures such as grooves and pipes to achieve the air guiding effect. The air guide channel 141 is formed by a combination of two partitions 141a. One end of the air guide channel 141 faces the second fan blade 13, and the other end extends toward the area where heat is easily accumulated; the air guide channel 141 can be set to pass through the heat accumulation area, or point to the heat accumulation area. The heat accumulation area refers to the position where heat is easily accumulated on the components such as the accommodating cavity, the motor frame 10, and the air guide plate 6. It is worth noting that the number, length and extension direction of the air guide channel 141 are not limited, and are specifically determined according to the area where heat is easily accumulated.

[0038] The cold air cavity is surrounded by an air guide cavity 14 that forms a semi-sealed cavity, which cooperates with the air guide channel 141 and the exhaust port 18. The space surrounded by the enclosure 142 is communicated with the mixed air outlet channel and the air guide cavity 14 to form air guiding and heat dissipation. The setting of the enclosure 142 limits the air outlet path of the second fan blade 13, so that the cold air can flow more concentratedly into the mixed air outlet channel and the air guide channel 141; thereby achieving cooling of the middle position and the peripheral position of the cold air cavity, and the excess airflow flows out from the exhaust port 18.

[0039] The structure of the enclosure 142 and the air guide channel 141 is simple, easy to implement and assemble, and the structure is added within the original space without increasing the overall volume of the cooking device. The second fan blade 13 drives the shell 1 and the accommodating cavity to cool, and the distribution process achieves heat dissipation in the heat accumulation area; through the structure of the air guide channel 141, the dual functions of driving and distributing the airflow in the air guide cavity 14 can be achieved. When using one second fan blade 13, multi-directional cooling of the whole and points can be achieved.

[0040] The housing 1 is provided with an exhaust port 18 , which is correspondingly connected to the exhaust passage and is used to exhaust excess air in the air guide cavity 14 .

[0041] Furthermore, an exhaust notch 143 connected to the air guide channel 141 is provided on the enclosure 142, and the height of the exhaust notch 143 corresponds to at least the height of the second fan blade 13. This design ensures that the second fan blade 13 will not be blocked by the enclosure 142 when it is discharging air, and the basic air intake can be guaranteed. The airflow generated at the connection point between the second fan blade 13 corresponding to the air guide channel 141 and the air guide cavity 14 is introduced into the air guide channel 141, ensuring the cooling effect on the heat accumulation area of ​​the accommodating cavity, the motor frame 10, the air guide plate 6 and other components. A hot air outlet is provided on one side of the air guide plate 6, and the exhaust port 18 is connected to the hot air outlet to discharge the hot air. The exhaust port 18 includes a mixed air outlet channel connected to both the exhaust channel and the hot air outlet. The cold air and the hot air will be mixed at the mixed air outlet channel, and then enter the exhaust port 18 for discharge.

[0042] The inner pot 3 is arranged in the shell 1, and is used to hold the pot body of the food to be fried. The inner pot 3 is placed on the upper part of the base 2, and the gap between the shell 1 and the inner pot 3 forms a sandwich space 4. A cold air inlet 5 connected to the sandwich space 4 is provided on the shell 1 or the base 2. As a preferred embodiment, the cold air inlet 5 preferably adopts bottom air inlet, which can be more beautiful and is conducive to the cold air flowing through the lower half of the entire shell 1, cooperating with the overall cold air circulation, improving the integrity of the cooling of the machine body, and helping to reduce the temperature of the entire machine body. When the cold air circulates, negative pressure appears at the position of the cold air cavity, and the cold air enters from the cold air inlet 5, flows into the sandwich space 4 and the accommodating cavity, and enters the cold air cavity to participate in the circulation; the accommodating cavity and the sandwich space 4 are respectively located on the upper and lower sides of the motor frame 10, and a connecting port 17 is provided on the motor frame 10, and the connecting port 17 connects the accommodating cavity, the sandwich space 4 and the air guide channel 141.

[0043] The motor frame 10 includes a motor frame body and an extended edge, the extended edge is located at the front side of the motor frame body, and a connecting port 16 is provided on the peripheral side of the motor frame body and the extended edge, so that the peripheral side of the motor frame body can be connected to the accommodating cavity and the interlayer space 4. It should be noted that the side where the extended edge is located corresponds to the position of the door panel, the upper end of the door panel is connected to the connecting port 16 where the extended edge is located, and the lower end of the door panel is connected to the cold air inlet 5, so that an interlayer space 4 is formed at the door panel, and the cold air enters from the cold air inlet 5, and the airflow enters the accommodating cavity upward from the two interlayer spaces 4 between the inner liner 3 and the outer shell 1 in the door panel.

[0044] In the present embodiment, two air guide channels 141 are provided, and the ends of the two air guide channels 141 extend to both ends of the horizontal side of the extension edge. In order to evenly distribute the airflow in the air guide cavity 14, the two air guide channels 141 are connected to the two quarter points of the air guide cavity 14, respectively, so as to ensure the amount of air entering each air guide channel 141 and the heat dissipation effect of the air guide channel on the heat accumulation areas of the accommodating cavity, the motor frame 10, the air guide plate 6 and other components. If more air guide channels 141 are provided, the starting ends of the air guide channels 141 can be evenly distributed in the air guide cavity 14, and the ends of the air guide channels 141 extend to the heat accumulation areas of the accommodating cavity, the motor frame 10, the air guide plate 6 and other components. In this way, while reasonably distributing the airflow, the space between the air guide plate 6 and the motor frame 10 can also be reasonably configured.

[0045] The end of the air guide channel 141 is sealed to the motor frame body, and an air outlet notch 17 is provided at the end of the motor frame body corresponding to the air guide channel 141. After passing through the air guide channel 141, the airflow enters the space where the connecting port 16 of the extended edge is located through the air outlet notch 17. In order to improve the circulation efficiency of the cold air, the interlayer space 4 where the connecting port 16 is located is set to be the narrowest in this embodiment, and when the airflow enters the connecting port 16, it is accelerated to increase the flow speed of the airflow.

[0046] In the cold air circulation, the airflow reaches the interlayer space 4 from the cold air inlet 5, and then enters the accommodating cavity and the cold air cavity in turn, cooling the entire body from bottom to top; in the cold air cavity, the cold air is guided to the area prone to heat accumulation through the air guide channel 141 for cooling, and an exhaust port 18 is also provided to realize the overall circulation of the cold air; after cooling the heat accumulation area, the air guide channel 141 will return to the interlayer channel for repeated circulation, so that the cold air circulation in the present invention is composed of an external circulation formed by the cold air inlet 5 and the exhaust port 18, and an internal circulation in which the air guide channel 141 participates, forming a circulation of the external circulation and the internal circulation as a whole, which can improve the cold air circulation effect and frequency.
