Abstract

A steam valve for a cooking utensil and the cooking utensil are provided. The steam valve includes a valve base, a bonnet and a barrier member. The bonnet and the valve base form a mounting chamber. The valve base has a steam inlet, and at least one of the valve base and the bonnet has a steam outlet. The barrier member is mounted in the mounting chamber, the barrier member and a top wall of the bonnet define a first passage therebetween, steam flows from the steam inlet via the first passage to the steam outlet, and a bottom wall of the valve base corresponding to the barrier member is disposed obliquely such that liquid flows back to the steam inlet.

First claim

What is claimed is:

a barrier member mounted in the mounting chamber, wherein the barrier member and a top wall of the bonnet define a first passage therebetween such that steam flows from the steam inlet via the first passage to the steam outlet, and a bottom wall of the valve base corresponding to the barrier member is disposed obliquely such that liquid flows back to the steam inlet, wherein the other end of the barrier member and the bottom wall of the valve base define a second passage therebetween for flowing of the liquid, the bottom wall of the valve base comprises a first inclined section located in the second passage, and the first inclined section is configured to guide the liquid to the steam inlet, wherein the barrier member comprises:
a flow guide portion comprising a blocking piece and a reinforcing rib, the blocking piece has a notch, the notch and the bottom wall of the valve base define the second passage, a plurality of blocking pieces is provided, the plurality of blocking pieces is distributed at intervals in an extending direction of the second passage, any two adjacent blocking pieces are connected to each other by the reinforcing rib, and the first inclined section is opposite to the notch.

2. The steam valve according to claim 1 , wherein the blocking piece is a flat plate or an arc shaped plate.

3. The steam valve according to claim 1 , wherein the reinforcing rib is located at an end of the blocking piece adjacent to the bonnet.

4. The steam valve according to claim 1 , wherein the barrier member further comprises:
a barrier portion spaced apart from the flow guide portion, the barrier portion is located at a side of the flow guide portion adjacent to the steam inlet, and an end of the barrier portion adjacent to the valve base is configured to be a guide section to guide the liquid to the steam inlet.

5. The steam valve according to claim 4 , wherein the guide section is connected to the bottom wall of the valve base.

6. The steam valve according to claim 4 , wherein a part of an inner surface of the bonnet and a part of an inner surface of the valve base cooperatively constitute a circumferential wall of the mounting chamber, and an end surface of the barrier portion opposite to the circumferential wall is spaced apart from the circumferential wall to form a third passage.

7. The steam valve according to claim 6 , wherein a distance between the barrier portion and the circumferential wall is 2 mm≤d≤3 mm.

8. The steam valve according to claim 6 , wherein the bottom wall of the valve base comprises at least one second inclined section, and the second inclined section is inclined towards the third passage to guide the liquid to the third passage.

9. The steam valve according to claim 8 , wherein a contact point between the barrier portion and the bottom wall comprises a point a and a point e, the point a is adjacent to a middle position of the barrier portion, the point e is adjacent to the third passage, a distance between the point a and a horizontal plane is ha, and a distance between the point e and the horizontal plane is he,
the flow guide portion comprises a first blocking piece and a second blocking piece, the second blocking piece is located between the first blocking piece and the barrier portion, a contact point between the second blocking piece and the bottom wall comprises a point b and a point f, the point b is adjacent to the notch, the point f is adjacent to the third passage, 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 and the bottom wall comprises a point c and a point g, the point c is adjacent to the notch, the point g is adjacent to the third passage, 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, and
the ha, he, hb, hf, hc and hg meet the following relation:

ha>he, hb>hf, hc>hg, <hf<he.

10. A cooking utensil, comprising:
a steam valve, the steam valve further comprising:
a bonnet;
a valve base forming a mounting chamber with the bonnet, the valve base having a steam inlet and at least one of the valve base and the bonnet having a steam outlet; and
a barrier member mounted in the mounting chamber, wherein the barrier member and a top wall of the bonnet define a first passage therebetween such that steam flows from the steam inlet via the first passage to the steam outlet, and a bottom wall of the valve base corresponding to the barrier member is disposed obliquely such that liquid flows back to the steam inlet, wherein the other end of the barrier member and the bottom wall of the valve base define a second passage therebetween for flowing of the liquid, the bottom wall of the valve base comprises a first inclined section located in the second passage, and the first inclined section is configured to guide the liquid to the steam inlet, wherein the barrier member comprises: a flow guide portion comprising a blocking piece and a reinforcing rib, the blocking piece has a notch, the notch and the bottom wall of the valve base define the second passage, a plurality of blocking pieces is provided, the plurality of blocking pieces is distributed at intervals in an extending direction of the second passage, any two adjacent blocking pieces are connected to each other by the reinforcing rib, and the first inclined section is opposite to the notch.

11. The cooking utensil according to claim 10 , wherein the blocking piece is a flat plate or an arc shaped plate.

12. The cooking utensil according to claim 10 , wherein the reinforcing rib is located at an end of the blocking piece adjacent to the bonnet.

13. The cooking utensil according to claim 10 , wherein the barrier member further comprises:
