Embodiment 3

A cooking appliance according to a third embodiment will be described below with reference to fig. 11. As shown in fig. 11, the cooking appliance according to the third embodiment has the same configuration as the cooking appliance according to the first embodiment except for the structure of the steam channel opening and closing device. Thus, structures having substantially the same functions as those in the first embodiment will not be described in detail herein for the sake of brevity.

As shown in fig. 11, the steam channel opening and closing device 36 includes a second closing member 361, and preferably, the second closing member 361 may be made of a material such as silicone rubber, etc. to make the sealing effect better. One end of the second closure member 361 is pivotably connected to the valve upper cover 43 at one side of the steam outlet 362, and the other end of the second closure member 361 is connected to the pressing lower cover 323 by a connecting rod 363. Further, one end of the link rod 363 is pivotally connected to one end of the second closure 361, and the other end of the link rod 363 is fixed to the pressing down cover 323.

In actual operation, when the ejector member 42 moves from the falling position to the pop-up position, the pressing of the lower cover 323 drives the connection rod 363 to move upward, so that the second closing member 361 is pivoted upward, thereby causing the second closing member 361 to seal the steam outlet 362. When the eject member 42 moves from the eject position to the fall-back position, pressing the lower cover 323 brings the connecting rod 363 downward, so that the second closing member 361 is pivoted downward in the opposite direction, and the steam outlet 362 communicates with the atmosphere.

According to the cooking utensil provided by the invention, the pop-up part is arranged on the micro-pressure valve, so that a user can conveniently take out the micro-pressure valve by grasping the pop-up part, the user can conveniently operate the micro-pressure valve, and the pop-up part can be in a falling-back position when the user performs cooking operation, so that the product integrity is stronger. Further, by providing the micro-pressure valve with the steam passage opening/closing device and associating the opening/closing of the steam passage opening/closing device with the position of the ejector, it is possible to prevent the user from being burned when the user grips the ejector and operates the micro-pressure valve. The scheme has the advantages of simple structure, convenient assembly and lower cost.
