The steam can flow through the first passage 41 and flow out through the steam outlet 13. The liquid can pass through a part of the first passage 41, and can slide down on the bottom wall 111 of the valve base 20 along the barrier member 30 due to large weight of the liquid, such that the liquid can flow back to the steam inlet 12.
In the steam valve 1 for the cooking utensil according to embodiments of the present disclosure, by disposing the barrier member 30 in the mounting chamber 11, the barrier member 30 can well change a flow passage structure inside the mounting chamber 11, and can be configured to guide a flow direction of the steam in the mounting chamber 11, such that the steam can be well discharged from the mounting chamber 11; furthermore, the barrier member 30 can have a barrier effect on the liquid such as the rice-water, the liquid can flow back along the barrier member 30, such that the back flow of the liquid in the mounting chamber 11 can be sped up, spill-proof effect of the steam valve 1 during a boiling stage can be greatly improved; and meanwhile, the barrier member 30 has a simple structure and arrangement, a low cost and is easy to achieve.

As illustrated in FIGS. 8 to 13, according to some embodiments of the present disclosure, the blocking piece 310 may be a flat plate or an arc shaped plate. Either the flat plate or the arc shaped plate can form a barrier effect on the liquid, and the liquid needs to flow over the blocking piece 310 when flowing through the barrier member 30. The flat plate or the arc shaped plate may also define a passage in the mounting chamber 11 for guiding the steam. Further, viewing from a direction from the steam inlet 12 to the steam outlet 13, the arc shaped plate is protruded 15 towards the steam outlet 13. It could be understood that, a center of curvature of the arc shaped plate and the steam inlet 12 are located at the same side of the arc shaped plate. Thus, the arc shaped plate can guide the liquid to flow towards the steam inlet 12. Further, the arc shaped plate may extend in a circumferential direction of the steam inlet 12.
As illustrated in FIGS. 2, 5 and 11, according to some embodiments of the present disclosure, the other end of the barrier member 30 and the bottom wall 111 of the valve base 20 may have a second passage 42 therebetween for flowing of the liquid. It could be understood that, at least part of an end surface of the barrier member 30 adjacent to the bottom wall 111 can be spaced apart from the bottom wall 111 to define the second passage 42, the liquid such as the rice-water can flow to the bottom wall 11 along the barrier member 30 after flowing through a part of the first passage 41, and flow through the second passage 42, due to the influence of gravity. Thus, the second passage 42 can guide the flowing of the liquid, thereby preventing the liquid from being retained at the barrier member 30.
As illustrated in FIGS. 8, 10 and 13, according to further embodiments of the present disclosure, the blocking piece 310 has a notch 311, the notch 311 and the bottom wall 111 of the valve base 20 define the second passage 42 therebetween, a plurality of blocking pieces 310 is provided, and the plurality of blocking pieces 310 is distributed at intervals in an extending direction of the second passage 42. The barrier member 30 further includes a reinforcing rib 320, any two adjacent blocking pieces 310 are connected to each other by the reinforcing rib 320. In other words, the barrier member 30 may include a plurality of blocking pieces 310 and a plurality of reinforcing ribs 320, in the direction from the steam inlet 12 to the steam outlet 13, the plurality of blocking pieces 310 is arranged at intervals, any two adjacent blocking pieces 310 may be provided with the reinforcing rib 320 therebetween, an end of the reinforcing rib 320 is connected to one blocking piece 310, and the other end of the reinforcing rib 320 is connected to the other blocking piece 310, and the plurality of reinforcing ribs 320 may connect the plurality of blocking pieces 310 together to form a whole. An end of each blocking piece 310 adjacent to the bottom wall 111 has the notch 311, a plurality of notches 311 of the plurality of blocking pieces 310 and the bottom wall 111 may define the second passage 42.
Thus, the liquid such as the rice-water can flow over one or the plurality of blocking pieces 310, the blocking piece 310 can form the barrier to the liquid, reduce a flow velocity of the liquid, and decrease flowing inertia of the liquid, such that, under the influence of gravity, the liquid can flow to the bottom wall 111 along the blocking piece 310, and flow to the second passage 41 through the notch 311, the liquid thus can flow back to the steam inlet 12, thereby avoiding a situation that the liquid flows to the steam outlet 13 to form a spill of the liquid.
As illustrated in FIGS. 2, 5, 10 and 13, in some embodiments of the present disclosure, the reinforcing rib 320 may be located at an end of the blocking piece 310 adjacent to the bonnet 10. It could be understood that, the reinforcing rib 320 between any two adjacent blocking pieces 310 is adjacent to a top end of the blocking piece 310. Thus, in a flow direction of the liquid, the top end of the blocking piece 310 is located upstream of a bottom end of the blocking piece 310. The liquid at the top end of the blocking piece 310 forms foam due to the presence of the steam and its own high temperature, and the reinforcing rib 320 can have a deforming effect. Furthermore, the arrangement of the reinforcing rib 320 is facilitated, and the arrangement of the reinforcing rib 320 is prevented from influencing the arrangement of the notch 311.

Thus, the barrier portion 32 can block direct communication between the second passage 42 and the steam inlet 12, and prevent the liquid flowing out of the steam inlet 12 from directly flowing from the steam inlet 12 to the second passage 42.
In further embodiments of the present disclosure, the guide section 321 may be connected to the bottom wall 111. Thus, the barrier portion 32 can be connected to the bottom wall 111. Further, the guide section 321 may be snapped with the bottom wall 111. For example, the bottom wall 111 may define a strip-shaped groove, and the end of the guide section 321 adjacent to the bottom wall 111 is configured to be snapped in the strip-shaped groove. In some examples of the present disclosure, the barrier portion 32 may be arc shaped plate. Thus, the guide section 321 may be formed into an arc shape, such that the guide section can guide the flow direction of the liquid.
As illustrated in FIG. 1, in some examples of the present disclosure, a part of the inner surface of the bonnet 10 and a part of the inner surface of the valve base 20 cooperatively constitute the circumferential wall 112 of the mounting chamber 11, and an end surface of the barrier portion 32 opposite to the circumferential wall 112 is spaced apart from the circumferential wall 112 to form a third passage 43.

As illustrated in FIGS. 8, 10 and 13, according to further embodiments of the present disclosure, the barrier member 30 may include a flow guide portion 31, and the flow guide portion 31 may include a blocking piece 310 and a reinforcing rib 320. The blocking piece 310 may have a notch 311, the notch 311 and the bottom wall 111 of the valve base 20 may define the second passage 42 therebetween, a plurality of blocking pieces 310 may be provided, and the plurality of blocking pieces 310 is distributed at intervals in an extending direction of the second passage 42. Any two adjacent blocking pieces 310 may be connected to each other by the reinforcing rib 320, and the first inclined section is opposite to the notch 311. In other words, the barrier member 30 may include a plurality of blocking pieces 310 and a plurality of reinforcing ribs 320, in the direction from the steam inlet 12 to the steam outlet 13, the plurality of blocking pieces 310 is arranged at intervals, any two adjacent blocking pieces 310 may be provided with the reinforcing rib 320 therebetween, an end of the reinforcing rib 320 is connected to one blocking piece 310, and the other end of the reinforcing rib 320 is connected to the other blocking piece 310, and the plurality of reinforcing ribs 320 may connect the plurality of blocking pieces 310 together to form a whole.
As illustrated in FIGS. 8, 10 and 13, an end of each blocking piece 310 adjacent to the bottom wall 111 has the notch 311, a plurality of notches 311 of the plurality of blocking pieces 310 and the bottom wall 111 may define the second passage 42. The part of the bottom wall 111 opposite to the notch 311 may form the first inclined section. Thus, the liquid such as the rice-water can flow over one or the plurality of blocking pieces 310, the blocking piece 310 can form the barrier to the liquid, reduce the flow velocity of the liquid, and decrease the flowing inertia of the liquid, such that, under the influence of gravity, the liquid can flow to the bottom wall 111 along the blocking piece 310, and flow to the second passage 41 through the notch 311, the first inclined section in the second passage 42 thus can guide the liquid to flow back towards the steam inlet 12, thereby avoiding the situation that the liquid flows to the steam outlet 13 to form the spill of the liquid.
As illustrated in FIGS. 8 to 13, in some embodiments of the present disclosure, the blocking piece 310 may be a flat plate or an arc shaped plate. Either the flat plate or the arc shaped plate can form a barrier effect on the liquid, and the liquid needs to flow over the blocking piece 310 when flowing through the barrier member 30. The flat plate or the arc shaped plate may also define a passage in the mounting chamber 11 for guiding the steam. Further, viewing from a direction from the steam inlet 12 to the steam outlet 13, the arc shaped plate is protruded 15 towards the steam outlet 13. It could be understood that, a center of curvature of the arc shaped plate and the steam inlet 12 are located at the same side of the arc shaped plate. Thus, the arc shaped plate can guide the liquid to flow towards the steam inlet 12. Further, the arc shaped plate may extend in a circumferential direction of the steam inlet 12.
As illustrated in FIGS. 2, 5, 10 and 13, in some embodiments of the present disclosure, the reinforcing rib 320 may be located at an end of the blocking piece 310 adjacent to the bonnet 10. It could be understood that, the reinforcing rib 320 between any two adjacent blocking pieces 310 may be adjacent to the top end of the blocking piece 310. Thus, in a flow direction of the liquid, the top end of the blocking piece 310 is located upstream of a bottom end of the blocking piece 310. The liquid at the top end of the blocking piece 310 forms foam due to the presence of the steam and its own high temperature, and the reinforcing rib 320 can have a deforming effect. Furthermore, the arrangement of the reinforcing rib 320 is facilitated, and the arrangement of the reinforcing rib 320 is prevented from influencing the arrangement of the notch 311.
As illustrated in FIGS. 8, 10 and 13, in some embodiments of the present disclosure, the barrier member 30 may further include a barrier portion 32, the barrier portion 32 is spaced apart from the flow guide portion 31, the barrier portion 32 may be located at a side of the flow guide portion 31 adjacent to the steam inlet 12, and an end of the barrier portion 32 adjacent to the valve base 20 is configured to be a guide section 321 to guide the liquid to the steam inlet 12. It could be understood that, the barrier portion 32 is located between the flow guide portion 31 and the steam inlet 12, the barrier portion 32 is spaced apart from the steam inlet 12 and the flow guide portion 31 separately, the bottom end of the barrier portion 32 may be in contact with the bottom wall 111 of the valve base 20, the liquid flowing out of the second passage 42 can flow to the bottom end of the barrier portion 32, and the bottom end of the barrier portion 32 can guide the flowing of the liquid. Thus, the barrier portion 32 can block direct communication between the second passage 42 and the steam inlet 12, and prevent the liquid flowing out of the steam inlet 12 from directly flowing from the steam inlet 12 to the second passage 42.
In further embodiments of the present disclosure, the guide section 321 may be connected to the bottom wall 111 of the valve base 20. Thus, the barrier portion 32 can be connected to the bottom wall 111. Further, the guide section 321 may be snapped with the bottom wall 111. For example, the bottom wall 111 may define a strip-shaped groove, and the end of the guide section 321 adjacent to the bottom wall 111 is configured to be snapped in the strip-shaped groove.
Further, as illustrated in FIGS. 8 to 13, the barrier portion 32 may be a flat plate or an arc shaped plate. Either the flat plate or the arc shaped plate can form a barrier effect on the liquid, and the liquid needs to flow over the barrier portion 32 when flowing through the barrier member 30. The flat plate or the arc shaped plate may also define a passage in the mounting chamber 11 for guiding the steam. Further, viewing from a direction from the steam inlet 12 to the steam outlet 13, the arc shaped plate is protruded 15 towards the steam outlet 13. It could be understood that, a center of curvature of the arc shaped plate and the steam inlet 12 are located at the same side of the arc shaped plate. Thus, the arc shaped plate can guide the liquid to flow towards the steam inlet 12. Further, the arc shaped plate extends in the circumferential direction of the steam inlet 12.
As illustrated in FIG. 1, in some examples of the present disclosure, a part of the inner surface of the bonnet 10 and a part of the inner surface of the valve base 20 cooperatively constitute the circumferential wall 112 of the mounting chamber 11, and an end surface of the barrier portion 32 opposite to the circumferential wall 112 is spaced apart from the circumferential wall 112 to form a third passage 43. Thus, the third passage 43 may be configured to communicate the guide section 321 with the steam inlet 12, the guide section 321 can guide the liquid to flow towards the third passage 43 and flow back from the third passage 43 to the steam inlet 12. In further examples of the present disclosure, the distance between the barrier portion 32 and the circumferential wall 112 may be 2 mm≤d≤3 mm. Thus, the rice-water flowing out of the steam inlet 12 a large volume due to high temperature and presence of foam, cannot pass between the barrier portion 32 and the circumferential wall 112, the steam can pass between the barrier portion 32 and the circumferential wall 112, the rice-water will be deformed after flowing over the barrier member 30, the volume will become smaller, such that the rice-water can pass between the barrier portion 32 and the circumferential wall 112, and flow back to the steam inlet 12.
Furthermore, the bottom wall 111 of the valve base 20 may include at least one second inclined section, and the second inclined section can be inclined towards the third passage 43, so as to guide the liquid into the third passage 43. It could be understood that, at least a part of the bottom wall 111 forms the second inclined section, and the second inclined section is configured to guide the liquid on the bottom wall 111 adjacent to the guide section 321 to incline towards the third passage 43. For example, as illustrated in FIG. 13, the bottom wall 111 may include two second inclined sections, the two second inclined sections are symmetrical relative to a center of the bottom wall 111, the cooking utensil is placed on the horizontal plane 16 in a use state, viewing in a direction from a middle position of the bottom wall 111 to the third passages 43 at two sides of the barrier portion 32, a distance between the bottom wall 111 and the horizontal plane 16 is gradually decreased. Thus, the second inclined section can further guide the liquid at the guide section 321 to flow towards the third passage 43 and then flow towards the steam inlet 12.
As illustrated in FIGS. 11 to 13, in some embodiments of the present disclosure, a contact point between the barrier portion 32 and the bottom wall 111 includes a point a and a point e, the point a is adjacent to a middle position of the barrier portion 32, the point e is adjacent to the third passage 43, a distance between the point a and the horizontal plane is ha, and a distance between the point e and the horizontal plane is he. The flow guide portion 31 includes a first blocking piece 310a and a second blocking piece 310b, the second blocking piece 310b is located between the first blocking piece 310a and the barrier portion 32, a contact point between the second blocking piece and the bottom wall 111 includes a point b and a point f, the point b is adjacent to the notch 311, the point f is adjacent to the third passage 43, a distance between the point b and the horizontal plane is hb, and a distance between the point f and the horizontal plane is hf. A contact point between the first blocking piece 310a and the bottom wall 111 includes a point c and a point g, the point c is adjacent to the notch 311, the point g is adjacent to the third passage 43, a distance between the point c and the horizontal plane is hc, and a distance between the point f and the horizontal plane is hg. The ha, he, hb, hf, hc and hg meet the following relation: ha>he, hb>hf, hc>hg, hg<hf<he. Thus, the back flow of the rice-water can be achieved.
As illustrated in FIG. 1, in some embodiments of the present disclosure, an end surface of the flow guide portion 31 opposite to the circumferential wall 112 is spaced apart from the circumferential wall 112 to form a fourth passage 44, and the fourth passage 44 may be communicated with the steam inlet 12 and the steam outlet 13. For example, the end surface of the flow guide portion 31 opposite to the circumferential wall 112 is spaced apart from the circumferential wall 112 to form the fourth passage 44, the end surface of the barrier portion 32 opposite to the circumferential wall 112 is spaced apart from the circumferential wall 112 to form the third passage 43, an end of the third passage 43 is communicated with an end of the fourth passage 44, the other end of the third passage 43 is communicated with the steam inlet 12, and the other end of the fourth passage 44 is communicated with the steam outlet 13. Thus, the steam can flow from the steam inlet 12 to the third passage 43, and flow from the fourth passage 44 to the steam outlet 13. In further embodiments of the present disclosure, a distance between the flow guide portion 31 and the circumferential wall 112 may be 2 mm≤d≤3 mm. Thus, the rice-water flowing out of the steam inlet 12 has the large volume due to high temperature and the presence of foam, cannot pass between the flow guide portion 31 and the circumferential wall 112, and the steam can pass between the flow guide portion 31 and the circumferential wall 112.

The steam and the rice-water can enter the mounting chamber 11 through steam inlet 12, the steam can flow through the first passage 41 and flow out through the steam outlet 13. The rice-water can pass through a part of the first passage 41, and can slide down on the bottom wall 111 of the valve base 20 along the barrier member 30 due to the large weight of the rice-water.

The second inclined section can guide the rice-water to flow towards two ends of the barrier portion 32.

The distance between the barrier portion 32 and the circumferential wall 112 may be 2 mm, 2.5 mm or 3 mm. The second inclined section can guide the rice-water to flow from the second passage 42 to the third passage 43, and then flow from the steam inlet 12 back to a cooker body of the cooking utensil.
