Further, in the case where the return port 4 includes a sink, it is preferable that a bottom surface of the sink is formed as an inclined surface in order to facilitate timely return of the cooking liquid in the recess 2. Therefore, the backflow liquid can be temporarily accumulated in the sink, when the accumulated backflow liquid exceeds the bearing force of the elastic plate 7, the elastic plate 7 is forced to deform to open the backflow port 4, at the moment, one end of the elastic plate 7 is connected above the backflow port 4, the force arm of the elastic plate 7 can be maximized, and cooking liquid such as rice water can push the lower part of the elastic plate 7 under the action of gravity.
In addition, the steam valve seat 14 of the invention comprises a return valve 6, the return valve 6 is arranged on the inner side wall 5 through a connecting structure, and the outer edge of the return valve 6 can be matched with the side surface and the bottom surface of the sinking groove. In this way, the return valve 6 and the steam valve seat 14 can be assembled as an assembly, thereby improving the assembly efficiency.
Further, in one form of the return valve 6, as shown in fig. 1, 3 and 4, the return valve 6 is an elastic plate 7, for example, made of heat-resistant and elastic heat-resistant silicone, wherein one end of the elastic plate 7 is detachably connected to the connecting structure. Thus, the elastic plate 7 is elastically deformed by the gravity of the cooking liquid to open the return port 4.
Or, alternatively, the elastic plate 7 is pushed for easy installation and easier backflow of the cooking liquid, and preferably, as shown in fig. 3 and 4, the elastic plate 7 is installed on the outer surface of the inner sidewall 5 of the recess 2. In this way, the elastic plate 7 is more easily deformed by the action of the return liquid without being blocked by the upper edge of the return port 4, while the elastic plate 7 does not block the flow of the steam.
In one form, one end of the elastic plate 7 is formed with a protruding part 8, the connecting structure is a mounting hole 9 formed on the inner side wall 5, and the protruding part 8 is elastically clamped in the mounting hole 9. Therefore, the installation and positioning of the elastic plate 7 can be realized only by extruding the protruding part 8 into the installation hole 9, and the elastic plate is convenient and quick to detach and clean.
Alternatively, one end of the elastic plate 7 may be connected to the inner sidewall 5 by a screw;
or, the connection structure is a convex column formed on the inner side wall 5, a positioning hole is formed at the upper end of the elastic plate 7, and the positioning hole can be matched with the convex column to enable the elastic plate 7 to be connected on the inner side wall 5.

In addition, as shown in fig. 1 and 2, the inner side wall 5 of the groove 2 and the inner periphery of the circumferential flange 1 are spaced apart from each other, so that the sunken groove has a longer length, such that the lower end of the elastic plate 7 can be located at an approximate middle position of the sunken groove, the two side surfaces of the sunken groove and the groove bottom surface of the sunken groove have a corresponding limiting function on the lower end of the elastic plate 7, and the two side surfaces of the longer sunken groove can also have a guiding effect on the deformation of the elastic plate 7 to define the swing track of the elastic plate 7.
In addition, to facilitate the backflow, the backflow port 4 is formed at the lowest position of the groove 2. In this way, the cooking liquid in the whole recess 2 will flow back to the return opening 4, and will not flow to the steam inlet 3 to generate resistance to the entering steam, in other words, the entering steam will not blow the liquid flowing back to the steam inlet 3 upwards to generate loud noise.
In addition, in order to improve the overflow preventing and bubble breaking effect, it is preferable that the inner size of the groove 2 is gradually enlarged from the steam inlet 3 to the return port 4.
