The invention provides a bubble breaking piece positioned in a cover body of an electric cooker, which is used for breaking bubbles of steam entering the cover body of the electric cooker from a cooking cavity of the electric cooker. The embodiment of the bubble breaking member of the present invention will be described in detail with reference to the embodiment in which the bubble breaking member is specifically applied to the cover body of the rice cooker.

As shown in fig. 1, 3, 4 and 5, a steam valve assembly is provided on the cover of the rice cooker, and the steam valve assembly includes a steam valve base 10 and a steam valve upper cover 20 covering the steam valve base 10.

The steam valve base 10 is provided with a steam outlet cavity 11 which penetrates through the steam valve base 10 along the vertical direction, the steam outlet cavity 11 is communicated with a cooking cavity of the electric cooker, and steam in the cooking cavity flows into a cover body of the electric cooker through the steam outlet cavity 11.

The steam valve upper cover 20 and the steam valve base 10 form a bubble breaking cavity 21, and the bubble breaking cavity 21 is communicated with the steam outlet cavity 11. The steam valve upper cover 20 is also provided with an air outlet 22 communicated with the outside. Therefore, steam in the cooking cavity of the electric cooker enters the bubble breaking cavity 21 through the steam outlet cavity 11 and then flows out through the air outlet 22. In this process, there often occurs a problem that bubbles in the steam escape from the air outlet 22. Therefore, the invention arranges a bubble breaking piece 30 in the bubble breaking cavity 21 and at the upper cavity of the steam outlet cavity 11, and a plurality of gaps 31 for breaking bubbles are arranged on the outer surface of the bubble breaking piece 30, and the plurality of gaps 31 are isolated from each other to form independent gaps, so that the bubble breaking piece 30 can be pushed to rotate through the gap 31 no matter which gap 31 faces the steam outlet cavity 11, so as to realize bubble breaking in the rotating process.

So, when steam goes out the gas cavity 11 and gets into brokenly bubble chamber 21 through steam, can earlier with this brokenly bubble piece 30 contact the back and get into brokenly bubble chamber 21 again, at this moment, steam can collide with the inner wall of breach 31 and the liquefaction flows back to the chamber of cooking of electric rice cooker, and the bubble in the steam also can be because of colliding with the inner wall of breach 31 and breaking to the problem that the bubble spilled over from gas outlet 22 has been solved.

In addition, when the steam flowing out of the steam outlet cavity 11 collides with the bubble breaking member 30, a certain acting force is generated on the bubble breaking member 30, when the acting force is large enough, that is, the steam flow rate is large enough, the force applied to the bubble breaking member 30 can make the bubble breaking member 30 rotate, and the rotation of the bubble breaking member 30 can generate stronger collision with the steam flowing out of the steam outlet cavity 11, so that more steam is liquefied, more bubbles are broken, and a further bubble breaking effect is obtained.

It must be said that, because the bubble breaking piece 30 is placed at the upper opening of the steam outlet cavity 11, the structure of the bubble breaking piece 30 only needs to meet the requirement that the bubble breaking piece does not fall into the steam outlet cavity 11 from the upper opening, and because the upper opening of the steam outlet cavity 11 is not too large, the structure of the bubble breaking piece 30 also does not need to be set too large to meet the requirement of breaking bubbles, that is, the bubble breaking piece 30 in the invention can realize effective bubble breaking treatment of steam in the limited cover body space of the electric rice cooker.

In order to further liquefy more steam and collapse more bubbles during the steam flowing through the bubble breaking member 30, a protruding portion (not shown) for breaking bubbles may be provided on the inner wall of the notch 31, such as some zigzag structures, small protrusions or some wrinkles, so that on one hand, the protruding portion may increase the surface area of the inner wall of the notch 31 to enhance the liquefying effect of the steam, and on the other hand, the protruding portion may break more bubbles to further prevent bubbles from flowing out of the air outlet 22.

Further, as shown in fig. 2, a plurality of notches 31 are formed in the bubble-breaking member 30, and are formed by opening the outer peripheral wall of the bubble-breaking member 30 inward, and a rib 32 is formed between adjacent notches 31, so that the steam flowing out of the steam outlet chamber 11 collides with the rib 32, thereby liquefying more steam and breaking more bubbles. Preferably, as shown in fig. 2, the bubble-breaking member 30 is spherical as a whole, the surface of the ridge portion 32 is substantially overlapped with the large circular surface of the bubble-breaking member 30, and the surface of the ridge portion 32 is three large circular surfaces which are perpendicular to each other in pairs. Specifically, the bubble breaking member 30 may have eight notches 31, and the eight notches 31 have substantially the same structure, so that the bubble breaking member 30 is a regular structure symmetrical with the three large circular surfaces, and when the bubble breaking member 30 rotates under the action of the steam, the rotation of the bubble breaking member has a certain continuity, so as to better break bubbles in the steam. Of course, in other embodiments, the surface of the ridge 32 may be parallel to the large circular surface of the bubble breaking member 30, so that more notches 31 may be provided as required to enhance the bubble breaking effect.

As shown in fig. 1, 4 and 5, the bubble breaking cavity 21 in the embodiment of the present invention is a cavity in which the steam valve upper cover 20 protrudes toward the steam valve base 10, and a through hole (not shown) penetrating through the lower bottom surface of the cavity is formed in the lower bottom surface of the cavity, and the bubble breaking cavity 21 is communicated with the steam outlet cavity 11 through the through hole. Specifically, the upper cavity of the steam outlet cavity 11 is approximately connected with the through hole, at this time, the bubble breaking piece 30 is just positioned at the through hole of the bubble breaking cavity 21 to break bubbles of the steam flowing out from the steam outlet cavity 11, and when the steam flowing out from the steam outlet cavity 11 is too much and still contains water vapor in the steam flowing out from the bubble breaking piece 30, the water vapor collides with the inner wall of the bubble breaking cavity 21, so that the steam flows back to the cooking cavity of the electric cooker from the steam outlet cavity 11 after being liquefied; meanwhile, when the bubble breaking piece 30 rotates under the action of steam, the bubble breaking piece 30 is always positioned near the connection part and does not deviate from the connection part more even if the rotating amplitude of the bubble breaking piece 30 is larger because the bubble breaking piece is just positioned at the connection part of the through hole and the upper cavity of the steam outlet cavity 11, so that the stability of bubble breaking is ensured.

Because the steam flowing out from the bubble breaking cavity 21 often contains more water vapor, if the steam is directly discharged from the air outlet 22 at this time, the cooking effect of the electric cooker is liable to be affected, and the problem of water shortage of cooked food can be caused, for this reason, as shown in fig. 1, fig. 4 and fig. 5, the air outlet 22 can be arranged at one side of the bubble breaking cavity 21, and meanwhile, a leakage hole 23 penetrating through the lower bottom surface of the bubble breaking cavity 21 is also arranged at the lower bottom surface of the bubble breaking cavity 21, so that the steam flowing out from the bubble breaking cavity 21 can flow out from the leakage hole 23, and finally flows out from the air outlet 22 to the outside, referring to fig. 5, an arrow therein indicates the flow direction of the steam, and it can be seen that, in the whole process that the steam flows out to the outside, the steam flowing out from the bubble breaking cavity 21 can continuously flow through a certain space in the cover body of the electric cooker, and in the whole process, the water vapor in the steam can be further liquefied, and at this time, some steam backflow holes (smaller backflow holes (for the liquefied liquid in the electric cooker) are arranged on the steam valve base 10) are arranged for backflow into the electric cooker. Preferably, a return valve 40 is disposed in the return hole, so that the steam in the cooking chamber of the rice cooker is prevented from flowing out of the return hole, and more steam and bubbles are generated at the air outlet 22.

As shown in fig. 1 and 3 to 5, in order to facilitate the user to observe the bubble breaking process of the bubble breaking member 30, the position of the steam valve upper cover 20 corresponding to the bubble breaking member 30 may be a transparent structure 50, so that when the bubble breaking effect of the bubble breaking member 30 is not good, the user can observe the bubble breaking member at the first time and then perform maintenance. In order to conveniently overhaul and maintain the foam breaking piece 30, the transparent structure 50 can be detachably mounted on the steam valve upper cover 20, for example, the transparent structure is connected through a buckle structure or a screw, and thus, when the foam breaking piece 30 needs to be overhauled and cleaned, the foam breaking piece 30 can be taken out only by detaching the transparent structure 50 from the steam valve upper cover 20. Wherein, the transparent structure 50 can be made of transparent food grade glass material or plastic material.

The invention also provides an electric cooker, which comprises the cover body of the electric cooker, the specific structure of the cover body of the electric cooker refers to the embodiments, and the electric cooker adopts all the technical schemes of all the embodiments, so that the electric cooker at least has all the beneficial effects brought by the technical schemes of the embodiments, and the details are not repeated.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
