The air fryer function is to heat food materials by using hot air, the fluidity of hot air is one of important factors affecting cooking effect, the air fryer function is to be realized in a cooking appliance, and a corresponding ventilation structure is required to be configured for realizing the air circulation of an internal cooking space and an external space. Referring to fig. 6 to 9, as in the present embodiment, two ventilation holes and two corresponding ventilation doors are provided on the side wall of the air guide cover 220 to realize air intake and exhaust of the air guide cover 220, for convenience of explanation, the two ventilation holes are respectively defined as an air intake hole 221 and an air exhaust hole 223, the corresponding ventilation doors are an air intake door 400 and an air exhaust door 600, as shown in fig. 8, when the pressure cooking function is realized, the air intake door 400 closes the air intake hole 221, the air exhaust door 600 closes the air exhaust hole 223, and the cooking cavity is a closed space, so that a high-temperature and high-pressure environment is generated after heating; as shown in fig. 9, when the air fryer function is implemented, the air inlet door 400 opens the air inlet hole 221, external air enters the air guide cover 220 through the air inlet hole 221 to participate in hot air circulation, the air outlet door 600 opens the air outlet hole 223, part of hot air flows out through the air outlet hole 223, the air inlet and the air outlet are not interfered with each other, and the hot air fluidity and the circulation efficiency inside the cooking cavity are enhanced.
The air inlet door 400 and the air outlet door 600 are both disposed on the inner side of the side wall of the air guide cover 220, two brackets 240 are correspondingly disposed on the outer side of the side wall of the air guide cover 220, taking the air inlet door 400 as an example, a driving rod 241 is mounted on the corresponding bracket 240, one end of the driving rod 241 penetrates through the side wall of the air guide cover 220 to connect with the air inlet door 400, the other end extends out of the bracket 240, the driving rod 241 moves radially inwards to drive the air inlet door 400 to open the air inlet hole 221 inwards, a return spring 242 is disposed on the driving rod 241, and the return spring 242 provides an acting force for the driving rod 241 to move radially outwards for returning after the air inlet door 400 is opened. The same driving manner is also applied to the exhaust damper 600.
To realize the above-mentioned opening and closing control of the air exhaust damper 600 and the air intake damper 400, corresponding driving structures are required to be configured, in this embodiment, the lock ring 230 is adopted to drive the air exhaust damper 600 and the air intake damper 400 to move, the rotational movement of the lock ring 230 is skillfully related to the movement of the air exhaust damper 600 and the air intake damper 400, and the opening and closing control of the air exhaust damper 600 and the air intake damper 400 is completed while the cooking function is switched, so that no separate driving structure is required to be configured for the air doors, and under the condition that the lock ring 230 and the hot air assembly 300 are already configured for the cover 200, the increase of the weight of the cover 200 due to the assembly of too many parts is avoided. Exemplary: the lock ring 230 extends upwards from the side surface to form two transmission blocks 232 with sheet structures, and the transmission blocks 232 and the transmission rods 241 are in bevel fit transmission, so that the circumferential rotation motion of the transmission blocks 232 is simply and effectively converted into the radial linear motion of the transmission rods 241.
Referring to fig. 8, when the locking ring 230 is at a position where the driving block 232 is offset from the driving rod 241 in the circumferential direction, the air inlet door 400 closes the air inlet hole 221, the air outlet door 600 closes the air outlet hole 223, and the cooking cavity forms a closed space to implement a pressure cooking function; when the locking ring 230 is rotated counterclockwise to the position shown in fig. 9, the driving block 232 acts on the driving rod 241, so that the air inlet door 400 opens the air inlet hole 221 and the air outlet door 600 opens the air outlet hole 223, thereby realizing the air fryer function. Switching from the pressure cooking function to the air fryer function is accomplished by rotation of the locking collar 230 and vice versa.
According to the cooking utensil, when the air fryer is implemented, the fan 310 acts to suck air below the air fryer and throw the air out from the side surface of the fan 310, the air is heated by the heating element 320 to form hot air, the side wall of the air guide cover 220 is provided with the air guide surface 224 for guiding the hot air downwards into the inner container 120, the air guide surface 224 is a circumferentially closed rotating curved surface, the hot air is guided by the air guide surface 224 to be led downwards into the inner container 120 and enter the lower part of the frying basket along the inner side wall of the inner container 120, the hot air enters the frying basket upwards to heat food, and finally the hot air is sucked by the fan 310, so that the hot air circulation in the cooking cavity is formed.
Referring to fig. 3 to 5, it can be seen that the air inlet 221 and the air outlet 223, the air inlet door 400 and the air outlet door 600, and the first sealing member 510 are all located in the hot air circulation path, and since the air inlet 221 and the air outlet 223 are used for circulating the air flow inside and outside the air guiding cover 220, the air inlet door 400 and the air outlet door 600 which are at the same height are not substantially effective for guiding the air flow downwards into the inner container 120, and the first sealing member 510 between the lower end of the sidewall of the air guiding cover 220 and the inner container opening of the inner container 120 is the necessary path for guiding the air flow downwards by the air guiding cover 220, if the first sealing member 510 is excessively protruded inwards from the air guiding surface 224 in the horizontal direction, the air flow downwards forms a large obstruction, and does not flow in the hot air circulation. Therefore, in the embodiment of the present invention, the horizontal distance between the first sealing member 510 and the center of the hot air assembly 300 is defined to be greater than the horizontal distance between the damper (including the air inlet damper 400 and the air outlet damper 600) and the center of the hot air assembly 300, and the center of the hot air assembly 300 is the rotation center o of the fan 310, so that the inner ring side of the first sealing member 510 is close to the air guiding surface 224 of the air guiding cover 220 as much as possible in the horizontal direction on the premise of not affecting the basic sealing performance of the first sealing member 510, and the air guiding surface 224 tends to be flatly transited to the inner surface of the inner container 120, so that the obstruction of the downward airflow of the first sealing member 510 is reduced, and the downward airflow along the air guiding surface 224 is smoothly blown into the inner container 120, thereby ensuring the cooking effect of the air fryer.
Specifically, the first sealing member 510 of the present embodiment includes an annular main body 511, a first sealing lip 512 and a second sealing lip 513 extending inward from the inner side of the annular main body 511, and an annular clamping groove 514 is defined between the three, so that the first sealing member 510 is clamped to the septum 500 along the edge of the septum 500, and the septum 500 is fixedly connected to the air guiding cover 220. Because the partition 500 is provided with the plurality of through holes 520 to form the ventilation area, in order not to influence the airflow circulation in the ventilation area, the horizontal projection of the first sealing member 510 is located outside the horizontal projection of the ventilation area, so that the influence of the first sealing member 510 on the airflow circulation due to the shielding of part of the ventilation area is avoided.
The first sealing lip 512 provides a seal between the air guide casing flange 222 and the first sealing member 510, and under the premise of ensuring the sealing performance, the horizontal distance L1 between the first sealing lip 512 and the center of the hot air assembly 300 is greater than the horizontal distance H between the damper and the center of the hot air assembly 300, i.e., the inner ring side of the first sealing lip 512 is made to be as close to the air guide surface 224 of the air guide casing 220 as possible in the horizontal direction, thereby reducing the obstruction of the downward air flow by the first sealing lip 512.
Preferably, the first sealing lip 512 extends upward and is attached to the air guiding surface 224, so as to increase the contact area between the first sealing lip 512 and the air guiding cover 220, thereby improving the sealing performance, and it should be noted that: the first sealing lip 512 is not attached to the whole air guiding surface 224, and considering the tightness and the influence on the air flow, the first sealing lip 512 only extends upwards for a small distance from the flange 222 of the air guiding cover, in the pressure cooking function, the first sealing lip 512 is attached to the inner surface of the air guiding cover 220 by means of the air pressure in the cooking cavity, so that the sealing effect is improved, and in the air fryer function, even if the first sealing lip 512 extends upwards and is attached to the air guiding surface 224, the horizontal distance L1 between the first sealing lip 512 and the center of the hot air component 300 is still greater than the horizontal distance H between the air door and the center of the hot air component 300, so that the obstruction of the air flow to the first sealing lip 512 is reduced.
Of course, in other embodiments, the first sealing lip may just cooperate with the flange of the air guiding cover to seal, in other words, the horizontal distance between the first sealing lip and the center of the hot air assembly is greater than or equal to the horizontal distance between the air guiding surface and the center of the hot air assembly, for example, the inner side of the first sealing lip is flush with the air guiding surface.
The second sealing lip 513 provides a seal between the liner opening of the liner 120 and the first sealing member 510, and on the premise of ensuring the sealing performance, the horizontal distance L2 between the second sealing lip 513 and the center of the hot air assembly 300 is greater than the horizontal distance H between the damper and the center of the hot air assembly 300, so that the obstruction of the downward air flow by the second sealing lip 513 is reduced.
In combination with the above embodiments, the inner ring side of the first sealing member 510, that is, the side of the first sealing lip 512 and the second sealing lip 513 facing the center of the hot air assembly 300, has a horizontal distance from the center of the hot air assembly 300 greater than that of the damper and the center of the hot air assembly 300, so that the obstruction of the downward air flow is reduced as much as possible when the downward air flow passes through the first sealing member 510, and the downward air flow is smoothly blown into the inner container 120.
Preferably, the air inlet door 400 includes a door frame capable of generating elastic deformation and a second sealing member wrapped outside the door frame, for example, the air inlet door 400 frame is made of metal sheet, and the air inlet sealing member is wrapped outside with silica gel material, so that the air inlet door 400 can generate deformation in the central direction of the air guide cover 220 to open the air inlet hole 221, and the second sealing member ensures the tightness of the air inlet door 400 when the air inlet hole 221 is closed, so as to prevent the air inlet hole 221 from generating air leakage in the pressure cooking function. The exhaust damper 600 is designed according to the same scheme as described above, and the horizontal distance between the damper and the center of the hot air assembly 300, that is, the horizontal distance between the second sealing member and the center of the hot air assembly 300.
Based on the multifunctional cooking appliance according to the above embodiment, in other embodiments, the first sealing member is fixedly connected to the air guiding cover, for example, a plurality of mounting holes are formed in the bottom of the air guiding cover along the circumferential direction, a plurality of mounting protrusions are correspondingly formed in the outer side of the first sealing member, the mounting protrusions are clamped on the mounting holes, so that the first sealing member is positioned at the bottom of the air guiding cover, and the first sealing member is tightly attached to the air guiding cover due to the pressure action of the pressure cooking function, so that no air leakage occurs at the mounting holes.
Based on the multifunctional cooking appliance according to the foregoing embodiment, in other embodiments, a damper driving device, such as a motor, a solenoid valve, an electromagnetic push rod, etc., is disposed on the cover, and the damper driving device drives the damper to act alone, taking an exhaust damper as an example: the air exhaust air door is installed on the air guide cover by referring to the scheme of the embodiment, the air door driving device is installed outside the air guide cover corresponding to the air exhaust air door, the transmission rod is connected with the air door driving device, and the air door driving device drives the air exhaust air door to act through the transmission rod to control the opening and closing of the air outlet.
While the invention has been described in terms of embodiments, it will be appreciated by those skilled in the art that the invention is not limited thereto but rather includes the drawings and the description of the embodiments above. Any modifications which do not depart from the functional and structural principles of the present invention are intended to be included within the scope of the appended claims.
