The upper end of the float sleeve 32 protruding out of the valve seat 31 has an inwardly recessed groove, the second sealing member 36 is clamped at the groove of the float sleeve 32, the second sealing member 36 includes a sealing member body 361 and a sealing extension 362, the sealing member body 361 is formed into a ring shape, the cross-sectional thickness of the sealing extension 362 is gradually reduced from inside to outside, and the inner end of the sealing extension 362 is connected with the sealing member body 361.
As shown in fig. 2, when the cooking utensil 100 is in an initial state (i.e., a normal state), the float rod 33 falls under the action of gravity, the elastic member 37 is in a compressed state, the elastic force of the elastic member 37 causes the third sealing member 34 to tightly contact with the lower surface of the float sleeve 32, the first air flow passage 302 is blocked, the sealing extending edge 362 of the second sealing member 36 contacts with the valve seat 31, and the contact surface between the sealing extending edge 362 and the valve seat 31 is small due to the small weight of the float rod 33.
When the cooking appliance 100 is operated, the temperature in the cooking cavity 11 gradually rises, air in the cooking cavity 11 expands, and cold air is discharged from the gap between the sealing extension 362 and the valve seat 31, so that cold air is discharged.
As shown in fig. 3, when the pressure in the cooking cavity 11 increases enough to overcome the weight of the float rod 33, the float rod 33 is pushed up by the pressure, the first sealing member 35 contacts the cover plate 202, and as the pressure increases, the first sealing member 35 is closer to the cover plate 202, the second air flow channel 301 is blocked, the third sealing member 34 is attached to the lower surface of the float sleeve 32 under the elastic force of the elastic member 37 and the pressure in the cooking cavity 11, and the first air flow channel 302 is kept in a sealed state, thereby realizing positive pressure sealing.
As shown in fig. 4, when air is pumped into the cooking cavity 11 to form a negative pressure state, the float rod 33 falls, the sealing extension 362 of the second sealing member 36 contacts the valve seat 31, and as the pressure in the cooking cavity 11 is smaller than the external pressure, the second sealing member 36 and the valve seat 31 are attached more and more tightly under the action of the external pressure and the gravity of the float rod 33, so as to block the second air flow channel 301, and the third sealing member 34 is attached to the lower surface of the float sleeve 32 under the action of the elastic force of the elastic member 37, so as to maintain the first air flow channel 302 in a sealing state, thereby realizing negative pressure sealing.
As shown in fig. 5, when the cooking appliance 100 needs to be opened after finishing working, the unlocking assembly 40 is operated, so that the unlocking assembly 40 moves downwards, the float rod 33 is driven to move downwards, the second sealing member 36 is attached to the valve seat 31, the unlocking assembly 40 overcomes the elastic force of the elastic member 37 to continuously press the float rod 33 downwards, the third sealing member 34 is separated from the lower surface of the float sleeve 32, the first air flow passage 302 is communicated, the cooking cavity 11 is communicated with the outside, and the opening is realized.
Other constructions and operations of the cooking appliance 100 according to the embodiment of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.
