The cooking appliance 100 according to the embodiment of the present application is described below with reference to FIGS. 1 to 5 .

The cooking device 100 according to the embodiment of the present application includes: an upper cover 10 , a base 20 , a grilling pan 40 and a heating assembly 50 .

Specifically, as shown in FIG. 3 , the upper cover 10 is connected to the base 20 and defines an internal space 30. The grilling pan 40 is installed in the internal space 30. The internal space 30 includes an air frying cavity 31 located above the grilling pan 40 and a heating cavity 32 located below the grilling pan 40. The heating assembly 50 is located in the heating cavity 32 and is used to heat at least one of the grilling pan 40 and the heating cavity 32. Heating.

It can be understood that when the cooking appliance 100 processes food, the food can be placed on the frying pan 40, and the frying pan 40 can be heated by the heating component 50 to achieve heating of the food, thereby realizing the frying and grilling function of the cooking appliance 100, or when the food is air-fried, the heating cavity 32 can be heated by the heating component 50, wherein the heating cavity 32 and the air-frying cavity 31 are connected, so that after the heating component 50 heats the air in the heating cavity 32, the hot air can flow into the air-frying cavity 31 to achieve heating of the food, thereby realizing the air-frying function of the cooking appliance 100.

Among them, the heating components 50 that realize the frying and grilling function or the air frying function of the cooking utensil 100 are all located in the heating cavity 32 below the frying and grilling plate 40. In this way, the heating components 50 do not need to be arranged on the upper cover 10, which is convenient for cleaning the upper cover 10 and for reasonably arranging the heating components 50 to save installation space and improve space utilization, thereby facilitating the miniaturization design of the cooking utensil 100.

For example, as shown in FIG. 1 , the cooking appliance 100 includes an upper cover 10 and a base 20 .

The upper cover 10 is installed on the base 20, and an operation panel 80 is provided on the front side of the base 20. The operation panel 80 can be electrically connected to the heating component 50 through the control component. In this way, the user can directly control the cooking mode (frying or air frying) of the cooking appliance 100 through the operation panel 80, so as to reduce the difficulty of operating the cooking appliance 100.

Exemplarily, the upper cover 10 and the base 20 are connected by a hinge so that the upper cover 10 can be flipped open or closed relative to the base 20, wherein when the upper cover 10 is flipped to a closed state relative to the base 20 (such as the state of the cooking utensil 100 in Figures 1 and 2), the upper cover 10 is used to close the internal space 30 to ensure the airtightness of the internal space 30, and when the upper cover 10 is flipped to an open state relative to the base 20 (such as the state of the cooking utensil 100 in Figure 3), the upper cover 10 opens the internal space 30 to facilitate the user to take and put food.

As shown in FIG. 3 , the internal space 30 includes an air-frying chamber 31 and a heating chamber 32 .

Specifically, the air-frying cavity 31 is defined by the upper cover 10 and the grilling pan 40 and is located above the grilling pan 40, the heating cavity 32 is defined by the base 20 and the grilling pan 40 and is located below the grilling pan 40, and the heating component 50 for realizing the grilling and air-frying functions of the cooking utensil 100 is located in the heating cavity 32.

When the cooking device 100 performs the grilling function, food can be placed on the grilling pan 40, that is, the food is located in the air-frying cavity 31, and then the grilling pan 40 is heated by the heating component 50 to achieve heating of the food, thereby achieving the grilling function of the cooking device 100; when the cooking device 100 performs the air-frying function, food can be placed on the grilling pan 40, that is, the food is located in the air-frying cavity 31, and then the heating cavity 32 is heated by the heating component 50, wherein the heating cavity 32 and the air-frying cavity 31 are connected, so that after the heating component 50 heats the air in the heating cavity 32, the hot air can circulate in the heating cavity 32 and the air-frying cavity 31 to achieve heating of the food, thereby achieving the air-frying function of the cooking device 100.

It is worth mentioning that the frying pan 40 can be used as a frying pan or a baking pan for frying and grilling food. At the same time, the frying pan 40 can also be used as a placing plate for placing food when air-frying food. In this way, when the cooking utensil 100 implements different cooking methods, the frying pan 40 can be used without replacement, which makes it easier to use the cooking utensil 100.

It should be noted that in the related art, the cooking utensil 100 also has frying and grilling functions, but its heating system (the heating component 50 in the present application) for realizing the frying and grilling functions and the air frying functions is arranged on the upper cover 10 or the two heating systems are respectively arranged on the upper cover 10 and the base 20. In this way, the heating system occupies the installation space of the upper cover 10, resulting in a larger size of the upper cover 10. Moreover, since the heating system is arranged on the upper cover 10, the space around the heating system on the upper cover 10 cannot be cleaned, that is, the upper cover 10 is difficult to clean.

In the present application, the heating component 50 is placed in the heating chamber 32 so that the heating component 50 does not need to be set on the upper cover 10, thereby saving the installation space of the upper cover 10, facilitating the miniaturization design of the upper cover 10, and facilitating the cleaning of the upper cover 10.

According to the cooking utensil 100 of the embodiment of the present application, its heating component 50 can heat at least one of the frying pan 40 and the heating cavity 32 to realize the frying function or the air frying function of the cooking utensil 100, and the heating component 50 is located in the heating cavity 32 below the frying pan 40, so that the heating component 50 does not need to be set on the upper cover 10, which is convenient for cleaning the upper cover 10, and it is convenient to save installation space, improve space utilization, and thus facilitate the miniaturization design of the cooking utensil 100.

In some embodiments, as shown in FIG. 3 , the heating assembly 50 includes a first heating element 51 and a second heating element 52 . The first heating element 51 is mounted on the base 20 and is used to heat the air in the heating cavity 32 . The second heating element 52 is mounted on the bottom of the grilling pan 40 and is used to heat the grilling pan 40 .

Thus, the heating cavity 32 and the grilling pan 40 can be heated by the first heating element 51 and the second heating element 52 respectively, so that the air frying function and the grilling function of the cooking device 100 can be independently realized.

Among them, the first heating element 51 is installed on the base 20 and is spaced apart from the grilling pan 40 in the up and down directions to avoid interference between the first heating element 51 and the grilling pan 40, and the second heating element 52 is installed on the side of the grilling pan 40 away from the air-frying cavity 31, so that the second heating element 52 can directly heat the grilling pan 40, thereby improving the heating efficiency of the second heating element 52 on the grilling pan 40.

Exemplarily, the first heating element 51 is located in the center area of the grilling pan 40 along the projection from top to bottom, and the second heating element 52 is located in the area close to the edge of the grilling pan 40 along the projection from top to bottom. Alternatively, the first heating element 51 is located in the area close to the edge of the grilling pan 40 along the projection from top to bottom, and the second heating element 52 is located in the center area of the grilling pan 40 along the projection from top to bottom.

Thus, in the up and down directions, the projections of the first heating element 51 and the second heating element 52 are located at different areas of the grilling pan 40. This facilitates reasonable layout to fully utilize the installation space on the one hand, and on the other hand, when the first heating element 51 and the second heating element 52 are used for heating at the same time, the heating areas of the two do not cross or overlap, thereby facilitating the expansion of the heating area and further improving the heating efficiency.

Furthermore, as shown in FIG. 3 and FIG. 4 , the heating assembly 50 further includes a fan 53 , which is mounted on the base 20 , and is used to guide the air in the heating chamber 32 to the air-frying chamber 31 .

Thus, when air frying food, the first heating element 51 heats the air in the heating chamber 32. The fan 53 guides the hot air in the heating cavity 32 into the air-frying cavity 31 to increase the flow rate of the hot air, thereby heating the food in the air-frying cavity 31 more quickly, thereby realizing the air-frying function of the cooking device 100.

Exemplarily, as shown in FIG. 4 , the first heating element 51 is configured as a heating pipe, and the heating pipe is distributed around the fan 53 .

Therefore, the air guiding efficiency of the fan 53 can be improved, and the installation space occupied can be reduced, which is conducive to realizing the miniaturized design of the cooking appliance 100.

It is worth noting that “the heating pipes are distributed around the fan 53” includes but is not limited to the heating pipes being constructed as a spiral structure and being sleeved on the outside of the fan 53, or the heating pipes being constructed as a plurality of heating pipes, and the plurality of heating pipes are spaced apart and distributed in the circumferential direction of the fan 53.

For example, as shown in FIG. 4 , the first heating element is constructed as a spiral heating tube, which is sleeved on the outside of the fan 53 and is spaced apart from the fan 53. In this way, the fan 53 can more comprehensively guide the hot air in the heating chamber 32 to the air frying chamber 31. At the same time, it is convenient to reduce the space occupied by the first heating element 51 and the fan 53, which is conducive to realizing their miniaturized design.

In some embodiments, as shown in FIG. 3 , an air inlet channel 42 is defined between the grilling pan 40 and the base 20 , and the grilling pan 40 is provided with an air return hole 41 , and both the air inlet channel 42 and the air return hole 41 are used to connect the heating cavity 32 and the air frying cavity 31 .

Therefore, when air-frying food, the first heating element 51 heats the air in the heating chamber 32, and then the fan 53 guides the hot air in the heating chamber 32 to the air-frying chamber 31 through the air inlet channel 42. After the hot air heats the food in the air-frying chamber 31, the air returns to the heating chamber 32 through the return air hole 41. In this way, the air in the heating chamber 32 and the air in the air-frying chamber 31 can form a circulation. The specific flow path of the air flow is shown by the dotted line with an arrow in FIG. 3, so as to increase the flow rate of the hot air, thereby heating the food in the air-frying chamber 31 more quickly, thereby realizing the air-frying function of the cooking device 100.

In some embodiments, as shown in FIG. 2-FIG . 4 , an oil-proof plate 43 is provided on the grilling pan 40 , and the oil-proof plate 43 is provided above the return air hole 41 , and the projection of the oil-proof plate 43 from top to bottom falls on the outer circle of the return air hole 41 .

Therefore, by providing the oil-proof plate 43, the oil-proof plate 43 can be used to shield the return air hole 41 in the up and down directions, and the projection of the oil-proof plate 43 from top to bottom falls on the outer circle of the return air hole 41. In other words, the outer peripheral edge of the oil-proof plate 43 protrudes out of the return air hole 41. In this way, when the oil above the oil-proof plate 43 slides to the bottom wall of the frying pan 40, the oil-proof plate 43 can prevent the oil from entering the return air hole 41, thereby preventing the oil from leaking out of the return air hole 41.

Furthermore, the grilling pan 40 is formed with a grilling plane 44 , and the grilling plane 44 is flush with the upper surface of the oil-proof plate 43 .

It should be noted that when the grilling pan 40 is heating food, the upper surface of the oil-proof plate 43 and the grilling plane 44 together serve as a plane for placing and grilling food.

Thus, the upper surface of the oil-proof plate 43 and the grilling plane 44 can be at the same level. In this way, when placing food such as steak on the grilling plane, it can be ensured that the steak and other food can fully contact the grilling plane, thereby improving the cooking effect.

In some embodiments, as shown in FIG. 3 , in the distribution direction of the grilling pan 40 and the fan 53 , at least a portion of the projection of the return air holes 41 falls on the fan 53 .

It should be noted that, when the fan 53 rotates, a low pressure is formed at the axial end of the fan 53, and the air pressure in the air-frying chamber 31 is relatively high due to the entry of hot air in the heating chamber 32. Therefore, by setting at least a portion of the projection of the return air hole 41 to fall on the fan 53 in the distribution direction of the grilling pan 40 and the fan 53, a pressure difference is formed between the return air hole 41 and the end of the intermediate axis of the fan 53. In this way, the pressure difference can be used to allow the hot air entering the air-frying chamber 31 from the heating chamber 32 to directly flow back to the vicinity of the fan 53 in the heating chamber 32 after passing through the return air hole 41, so as to improve the air return efficiency.

In some embodiments, as shown in FIG. 3 , an air inlet passage 42 is formed between a peripheral edge of the grill pan 40 and the base 20 .

Therefore, after the grilling pan 40 is installed in the internal space 30, the air inlet channel 42 can be directly defined by the circumferential edge of the grilling pan body and the base 20. On the one hand, there is no need to set up a separate air inlet pipeline, which reduces the difficulty of forming the air inlet channel 42 and helps to simplify the structure of the cooking utensil 100.

It should be noted that, when the fan 53 rotates, the rotation of the fan 53 will blow the air heated by the first heating element 51 to form a hot air flow, and due to the rotation of the fan 53, most of the hot air flow will flow radially outward along the fan 53, and the air inlet channel 42 is set between the circumferential edge of the frying pan 40 and the base 20, so that the setting position of the air inlet channel 42 can conform to the blowing law of the fan 53 on the hot air, thereby facilitating the hot air flow from the air inlet channel to the air frying cavity 31, and then heating the food in the air frying cavity 31.

In some embodiments, as shown in Fig. 3, the cooking appliance 100 further includes a driving motor 61, the driving motor 61 is mounted on the base 20, and the fan 53 is sleeved on the output shaft of the driving motor 61. Thus, by providing the driving motor 61, the rotation or stop of the fan 53 can be controlled by the driving motor 61.

In some embodiments, as shown in Figure 5, the cooking appliance 100 also includes a heat dissipation fan 62, a heat dissipation duct 21 is provided in the base 20, the heat dissipation duct 21 is provided with an air inlet 211 and an air outlet 212, the air outlet of the heat dissipation fan 62 is connected to the air inlet 211, and the drive motor 61 is located between the air inlet 211 and the air outlet 212.

Therefore, by providing the heat dissipation duct 21 and the heat dissipation fan 62, when the cold air is blown out from the air outlet of the heat dissipation fan 62, the cold air can flow along the heat dissipation duct 21 to the air outlet 212, and in the process of the cold air flowing, since the drive motor 61 is located between the air inlet 211 and the air outlet 212, the cold air can dissipate the heat of the drive motor 61, thereby facilitating the reduction of the temperature of the drive motor 61 and facilitating the extension of the service life of the drive motor 61.

It should be noted that, since the drive motor 61 generates heat when controlling the fan 53 to rotate, this will cause the temperature of the drive motor 61 to be too high. If the heat is not dissipated in time, the drive motor 61 will be damaged, thereby reducing the service life of the drive motor 61. In the related art, a cooling fan is usually arranged coaxially with the fan 53 on the output shaft of the drive motor 61. However, this will increase the size of the drive motor 61 in the axial direction (such as the up and down direction in FIG. 3 ), thereby increasing the heat dissipation of the drive motor 61. This results in the base 20 being too thick in the up-down direction, which is not conducive to realizing a miniaturized design of the cooking appliance 100 .

In the present application, the heat dissipation fan 62 is arranged on the base 20, and the heat dissipation of the driving motor 61 is achieved through the heat dissipation duct 21. In this way, the setting of the heat dissipation fan 62 will not occupy the axial size of the driving motor 61, thereby not causing the thickness of the base 20 in the up and down directions to be too large, so that the base 20 can be made thinner, so as to reduce the production cost and facilitate the miniaturization design of the cooking appliance 100.

Exemplarily, the base 20 is provided with air duct partition ribs 213 so as to define the heat dissipation air duct 21 through the air duct partition ribs 213 .

Furthermore, as shown in FIG. 5 , the cooking appliance 100 further includes a power board 63 , which is located in the heat dissipation duct 21 and electrically connected to the drive motor 61 . In the flow direction of the cold air in the heat dissipation duct 21 , the drive motor 61 is located downstream of the power board 63 .

Therefore, when cold air flows in the heat dissipation duct 21, the flow path of the cold air is shown by the arrow in Figure 5, and the cold air can dissipate heat to the power board 63 and the drive motor 61 in turn. Since the heat generated by the power board 63 is usually less than the heat generated by the drive motor 61, the drive motor 61 is arranged downstream of the power board 63 in the flow direction of the cold air in the heat dissipation duct 21. This can avoid the excessive heat of the drive motor 61 from affecting the power board 63, which is beneficial to ensuring the heat dissipation effect of the power board 63.

In some embodiments, a first oil leakage hole 45 is provided on the grilling pan 40 , an oil receiving box 70 is provided in the base 20 , and the first oil leakage hole 45 falls into the bearing space of the oil receiving box 70 along the projection from top to bottom.

It should be noted that when the cooking device 100 is cooking food, oil will overflow from the food due to the heat, and the oil will temporarily remain on the frying pan 40. If the oil is not discharged in time, it will cause safety hazards and affect the cooking effect.

Therefore, in the present application, by providing the oil collecting box 70 and the first oil leakage hole 45, the oil on the frying and grilling pan 40 can be discharged into the carrying space of the oil collecting box 70 through the first oil leakage hole 45, thereby achieving the discharge of the oil, thereby improving the safety of use of the cooking utensil 100 and improving the cooking effect.

Furthermore, a second oil leakage hole 22 is provided on the base 20 , the first oil leakage hole 45 is communicated with the second oil leakage hole 22 , and the second oil leakage hole 22 is communicated with the oil receiving box 70 .

Thus, the first oil leakage hole 45 is connected between the air-frying cavity 31 and the second oil leakage hole 22, so that the oil on the frying pan 40 can enter the bearing space through the first oil leakage hole 45 and the second oil leakage hole 22 in sequence, thereby reducing the difficulty of discharging the oil.

Exemplarily, the oil receiving box 70 is detachably connected to the side of the base 20 .

Therefore, it is convenient for the user to take out and put the oil receiving box 70 , and further convenient for the user to clean the oil receiving box 70 .

In some embodiments, guide ribs are disposed on the inner side of the upper cover 10 , and the guide ribs can guide the hot air to the center of the air-frying cavity 31 .

Therefore, by providing the guide ribs, the hot air can be gathered more quickly and more concentratedly to the center of the air frying chamber 31. Thereby making it easy to improve the heating efficiency of hot air to food.

The following describes a cooking appliance 100 according to an embodiment of the present application in conjunction with FIGS. 1-5 :

The cooking appliance 100 includes an upper cover 10 , a base 20 , a grilling pan 40 , a heating assembly 50 , a driving motor 61 , a power board 63 and a heat dissipation fan 62 .

The upper cover 10 is installed on the base 20, and an operation panel 80 is provided on the front side of the base 20. The operation panel 80 can be electrically connected to the heating component 50 through the control component. In this way, the user can directly control the cooking mode (frying or air frying) of the cooking appliance 100 through the operation panel 80, so as to reduce the difficulty of operating the cooking appliance 100.

Exemplarily, the upper cover 10 and the base 20 are connected by a hinge so that the upper cover 10 can be flipped open or closed relative to the base 20, wherein when the upper cover 10 is flipped to a closed state relative to the base 20 (such as the state of the cooking utensil 100 in Figures 1 and 2), the upper cover 10 is used to close the internal space 30 to ensure the airtightness of the internal space 30, and when the upper cover 10 is flipped to an open state relative to the base 20 (such as the state of the cooking utensil 100 in Figure 3), the upper cover 10 opens the internal space 30 to facilitate the user to take and put food.

Furthermore, the frying pan 40 is installed on the base 20, and the frying pan 40 divides the internal space 30 into an air frying cavity 31 and a heating cavity 32 in the up and down directions, that is, in the up and down directions, the cavity between the frying pan 40 and the upper cover 10 is the air frying cavity 31, and the cavity between the frying pan 40 and the base 20 is the heating cavity 32, and the heating component 50 is installed in the heating cavity 32.
