Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 to 11, the cooking appliance of the present embodiment includes an appliance body 10 and a lid body 20. Wherein, the utensil body 10 comprises a pot body and a middle plate arranged on the pot body, and a matching structure 30 is arranged on the middle plate; the cover body 20 includes a cover body 21, an exhaust channel disposed on the cover body 21, a pressure limiting valve 22 sealed at an exhaust port of the exhaust channel, a movably disposed switching pressure button 23, and a movably disposed switching plate 24, where the switching pressure button 23 has a first position that does not affect a position of the pressure limiting valve 22 and a second position that makes the pressure limiting valve away from the exhaust port, the switching plate 24 can lock the switching pressure button 23 and make the switching pressure button 23 maintain the second position, and before the cover body 20 is screwed to the locking position of the appliance body 10, the switching plate 24 can cooperate with the cooperating structure 30 to make the switching plate 24 away from the switching pressure button 23 so that the switching pressure button 23 can be located at the first position.

By applying the technical scheme of the embodiment, when pressure cooking is required, the pressure switching button 23 is located at the first position, and at the moment, the pressure limiting valve 22 is blocked at the air outlet, so that the pressure of the cooking cavity in the appliance body 10 can be increased, and pressure cooking is realized. When pressure-regulating cooking is required, the switching pressure button 23 is switched to the second position, and at this time, the switching plate 24 can cooperate with the switching pressure button 23 to keep the switching pressure button 23 at the second position. When the switching pressure key 23 is located at the second position, the switching pressure key 23 can drive the pressure limiting valve 22 to be far away from the exhaust port, so that the cooking cavity is communicated with the external atmosphere, and pressure-regulating cooking is realized. The cooking mode of the cooking utensil is switched through the mechanical structure, the problem that an electromagnetic structure is easy to damage in the background technology is avoided, switching of the pressure and pressure regulating cooking modes is more reliable, and finally use experience of a user is improved.

It should be noted that, in the embodiment, before the cover 20 is covered on the appliance body 10, if the switching pressure button 23 is pressed to the second position by the user carelessly, before the cover 20 is screwed to the locking position, the switching plate 24 will be engaged with the engaging structure 30 on the appliance body 10 and away from the switching pressure button 23, so as to reset the switching pressure button 23 to the first position. After the cover 20 is screwed to the locking position, if the user needs to adjust the pressure for cooking, the switch pressure button 23 can be pressed to the second position. By the structure, even if a user mistakenly presses the switching pressure key 23 before the cover body 20 is screwed to the locking position, the switching pressure key 23 can be automatically reset after the cover body 20 is screwed to the locking position, redundant operation is not needed by the user, and the use experience of the user is improved.

The lid 20 has an unlock position for unlocking the appliance main body 10, and when the lid 20 is in the unlock position, the lid 20 can be opened from the appliance main body 10.

Above-mentioned structure makes the user needn't open lid 20 and to the lower cover process that closes lid 20 when pressure regulating cooks the back again after accomplishing, only needs the user to close lid 20 soon, therefore above-mentioned structure can reduce user's operating procedure, improves user's use and experiences. Of course, in other embodiments not shown in the drawings, before the cover body is screwed to the unlocking position, the switch board can be matched with the matching structure to make the switch board away from the switching pressure key. The structure can effectively reduce the screwing angle of the cover body, thereby improving the use experience of a user.

As shown in fig. 8 to 10, 11 and 14, in the present embodiment, the engagement structure 30 includes a second guiding inclined surface 321, the second guiding inclined surface 321 gradually inclines toward the outer side of the cover 20 in the direction of screwing the cover 20 to the unlocking position, and the switch plate 24 is provided with a second engagement surface 242 engaged with the second guiding inclined surface 321. Specifically, when the cover 20 is rotated to the unlocking position, the second engagement surface 242 abuts against the second guiding inclined surface 321, and as the cover 20 continues to rotate in the above direction, the second guiding inclined surface 321 gradually pushes the switch plate 24 to the outside, so that the switch plate 24 is away from the switch pressure button 23. When the cover 20 is screwed to the unlock position, the first guiding inclined surface 311 of the switch plate 24 abuts against the first engagement surface 241 to keep the switch plate 24 at a position away from the switching pressure button 23. The structure is simple and easy to realize.

Of course, in other embodiments, if the switch board and the matching structure are magnetically matched, when the cover 20 is screwed to the unlocking position, the magnetic force can drive the switch board to move away from the switching pressure button, and the switch board is kept at a position away from the switching pressure button. Above-mentioned simple structure reduces user's operating procedure, improves user's use and experiences the basis for do not have direct contact between switch board and the cooperation structure, improved cooking utensil's reliability.
