In this embodiment, a handle 700 is disposed on a side surface of the outer cover 210, the handle 700 drives the locking ring 230 to rotate so as to complete the rotational locking or rotational unlocking of the locking ring 230 and the appliance body 100, as shown in fig. 11 and 12, when the cover body 200 is in a closed state, the handle 700 is shifted to the left side of the handle hole 211, the locking ring 230 is located at a position where the transmission block 233 and the transmission rod 241 are circumferentially staggered, the air inlet door 400 closes the air inlet hole 221, the air outlet door 600 closes the air outlet hole 223, and the pressure cooking cavity forms a closed space so as to implement a pressure cooking function; as shown in fig. 13, when the handle 700 is moved to the right side of the handle hole 211, the locking ring 230 rotates counterclockwise to the position shown in fig. 14, the driving block 233 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, so as to realize the air fryer function. The switching of the pressure cooking function to the air fryer function is accomplished by the rotation of the locking ring 230 and vice versa.
In this embodiment, since the handle 700 is transferred to the side of the outer cover 210 of the cover body 200, the handle 700 is far away from the center of the locking ring 230, and a relatively small force is applied to the handle 700 to achieve a rotation torque required for opening and closing the cover, so that the cover opening and closing operation is more labor-saving.
In this embodiment, the wind scooper 220 is further provided with a first limiting member, and the lock ring flange 231 is axially limited between the first limiting member and the wind scooper flange 222, so as to avoid the problem that the lock ring 230 moves up and down during use. Because the bracket 240 for assembling the air door is arranged on the wind scooper 220 in the above solution, the bracket 240 can be used as a first limit piece, and in order to balance the stress of the lock ring 230, one or more brackets are added on the basis of the original two brackets 240, as shown in fig. 5, three brackets 240 are arranged on the wind scooper 220 along the circumferential direction, and the lock ring 230 is axially limited at three positions in the circumferential direction of the lock ring flange 231.
With reference to fig. 5, preferably, an elastic pin is further disposed at the bottom of each support 240, the elastic pin abuts against the locking ring flange 231, and the elastic pin elastically stretches in the axial direction, so that not only can the axial limiting effect on the locking ring 230 be achieved, but also the difficulty in rotating caused by excessively pressing the locking ring 230 can be avoided. The following are exemplary: the elastic pin comprises an elastic element 244 and a limit pin 243, the bracket 240 is provided with a pin hole 245, the elastic element 244 and the limit pin 243 are assembled in the pin hole 245, the elastic element 244 supports the limit pin 243 downwards, part of the limit pin 243 extends out of the pin hole 245 to abut against the lock ring flanging 231, and the limit pin 243 can be spherical or cylindrical.
Referring to fig. 9, preferably, the upper surface of the wind scooper flange 222 is provided with a rib 224, the rib 224 may be continuously or intermittently arranged along the circumferential direction of the wind scooper flange 222, and the rib 224 is supported between the wind scooper flange 222 and the lock ring flange 231, so that the contact area between the wind scooper flange 222 and the lock ring flange 231 is reduced, the sliding resistance of the lock ring flange 231 is reduced, and the rotation of the lock ring 230 is smoother. In other embodiments, the ribs can also be arranged on the lower surface of the lock ring flange to play the same role.
Based on the multifunctional cooking utensil of the above embodiments, in another embodiment, the radial position limitation on the lock ring 230 is added, referring to fig. 7-9, a second position limiting member is disposed on the lock ring 230, the second position limiting member cooperates with the wind scooper 220 to radially limit the lock ring 230, so as to limit the deviation of the lock ring 230 in the radial direction of the lid body 200, and the lock ring 230 rotates more stably. The following are exemplary: the second limiting member is a plurality of rollers 232 circumferentially arranged on the lock ring flange 231, after the lock ring 230 is assembled with the wind scooper 220, the side surfaces of the rollers 232 contact the side wall of the wind scooper 220 to limit the deviation of the lock ring 230 in the radial direction of the cover body 200, when the lock ring 230 rotates relative to the wind scooper 220, the rollers 232 roll along the side wall of the wind scooper 220, the rolling friction resistance is small, and the rotation of the lock ring 230 is prevented from being influenced by excessive friction resistance while the radial limiting is realized.
In the above example, under the radial limiting action of the roller 232, a certain gap is kept between the lock ring flange 231 and the side wall of the wind scooper 220, so as to avoid frictional wear and frictional noise between the lock ring flange 231 and the side wall of the wind scooper 220, reduce the contact area between the lock ring 230 and the wind scooper 220, and ensure the smooth rotation of the lock ring 230.
