Description
Technical Field

Steam valves are commonly used to regulate the internal operating pressure of the rice cooker and to vent steam. The steam valve comprises a valve cover and a valve seat, an air inlet communicated with the inner cavity of the steam valve is arranged on the valve seat, and an air outlet is arranged on the valve cover. In the boiling stage of quick cooking and porridge cooking, a large amount of bubbles are generated when the water level in the electric cooker rises, after the bubbles enter the steam valve from the air inlet, part of the bubbles impact the top wall of the valve cover to be broken, and part of the bubbles are directly discharged to the outside of the electric cooker through the air outlet to pollute the electric cooker and the table top due to overlarge impulsive force during boiling.
There are proposals in the prior art to break up bubbles by extending the flow path of the steam, however, in such proposals the design of the bubble breaking structure is generally relatively complex and not compact. In addition, there are schemes in the prior art for breaking bubbles by providing bubble breaking balls rolling back and forth on the passage of steam, however, in such schemes there are still a number of problems: on one hand, the collision between the bubble breaking ball and the inner wall of the steam channel can generate larger noise; on the other hand, when the bubble breaking ball deviates on the steam channel, uneven bubble breaking is caused, and further, the bubble breaking effect is reduced because the bubble breaking ball is relatively static when rising to the highest point of the steam channel. Accordingly, there is room for improvement in the existing steam valve structure.

Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
The invention provides a steam valve, wherein a valve cavity is formed in the steam valve, and a foam breaking assembly is arranged in the valve cavity and comprises a foam breaking cavity and a foam breaking piece 10 arranged in the foam breaking cavity. The bubble breaking cavity has a steam inlet 101 and a steam outlet 101'. The foam breaking member 10 is rotatably mounted in the foam breaking cavity.
In the steam valve in the prior art, the foam breaking piece generally rolls back and forth along the bottom wall which is obliquely arranged in the foam breaking cavity under the action of the vapor pressure so as to break the foam. The bubble breaking piece is easy to deviate in the rolling process, bubbles can only be broken randomly, and large bubbles easily escape into the valve cavity, so that the bubble breaking effect is required to be improved. In addition, the bubble breaking piece can generate friction and collision noise in the rolling process, so that the working noise of the steam valve is increased.
In the technical solution of the present invention, since the foam breaking member 10 is arranged to rotate relative to the inner wall of the foam breaking cavity, in particular, the foam breaking member can rotate under the action of the pushing force generated by the steam. Such that foam, after entering the foam breaking cavity from the steam inlet 101, passes through the air bubble passage between the foam breaking member 10 and the foam breaking cavity. The foam will push the foam breaking member 10 to rotate as it passes through the bubble passage, and the foam breaking member 10 will squeeze the foam, breaking up relatively larger bubbles into small bubbles. In the technical scheme of the invention, the foam breaking member 10 is rotated by utilizing the resistance change generated when the foam passes through the foam breaking member 10, and in addition, the foam breaking member 10 rotates to squeeze the foam to break the foam, so that the invention provides a foam breaking structure and mode completely different from the prior art.
In addition, the technical scheme of the invention can better maintain the pressure difference between the steam inlet 101 and the steam outlet 101 'of the steam valve because the foam breaking member 10 is rotatably arranged at a fixed position, so that the steam inlet 101 has relatively high pressure, and foam can be continuously pushed to the steam outlet 101' for discharge.
As shown in fig. 1, the bubble breaking chamber includes a bottom wall 21, side walls 22 located on both sides of the bottom wall, and a top wall 23 disposed opposite the bottom wall. The foam breaker 10 is rotatably secured to the side wall 22 by a shaft 24. In this case, the foam breaker 10 will remain spaced from the bottom wall 21 and the top wall 23 and be rotatable relative to the bottom wall 21 and the top wall 23. When the distance between the foam breaking member 10 and the bottom wall 21 is greater than the distance between the foam breaking member 10 and the top wall 23, as shown in fig. 3, foam will preferentially pass under the foam breaking member 10, and the foam will push the foam breaking member 10 to rotate counterclockwise. When the distance between the foam breaking member 10 and the top wall 23 is greater than the distance between the foam breaking member 10 and the bottom wall 21, as shown in fig. 4, foam will preferentially pass over the foam breaking member 10.
In order to facilitate the backflow, as shown in fig. 2, an upper bubble passage 20 and a lower bubble passage 30 are formed between the bubble breaking member 10 and the top wall 23 and the bottom wall 21, respectively, and the cross-sectional area of the upper bubble passage 20 is different from that of the lower bubble passage 30. Preferably, the upper bubble channel 20 is of a different width than the lower bubble channel 30. More preferably, the width of the lower bubble channel 30 is greater than the width of the upper bubble channel 20. In addition, since the bottom wall 21 is provided obliquely, specifically, the height of the bottom wall 21 gradually increases from the steam inlet 101 to the steam outlet 101'. Thus, the foam passes through the lower bubble passage 30 with less resistance, and after the foam is crushed by the crushing member 10, it becomes water to flow back to the steam inlet 101 along the bottom wall 21.
Further, the steam valve comprises a guiding body 13 for guiding the foam only through the lower bubble passage 30 between the foam breaking member 10 and the bottom wall 21. Specifically, the guide body 13 includes a first wall 131 for shielding foam from entering the upper bubble channel 20, and a second wall 132 for guiding foam into the lower bubble channel 30. The guide body 13 has a size matching that of the bubble breaking cavity, and is installed in the bubble breaking cavity between the steam inlet 101 and the bubble breaking member 10. The first wall 131 of the guide body 13 may be a straight wall, which shields the upper region of the steam inlet 101 so that foam can only enter the lower bubble passage 30 between the bottom wall 21 and the breaking member 10 from the lower region of the steam inlet 131. The second wall 131 of the guide body 13 is an inclined wall, the bottom surface of which is parallel to the bottom wall 21 at the steam inlet 101. Thereby, a relatively uniform speed of the foam flow can be ensured. In addition, the guide body 13 further includes an arc surface 133 disposed opposite the foam breaker 10, and the foam breaker 10 may be partially accommodated in the arc surface 133. The bottom of the arcuate surface 133 transitions smoothly with the foam breaking member 10. Thereby, the storage of foam in the bubble passage between the guide body 13 and the foam breaking member 10 can be prevented.
In a preferred embodiment of the present invention, the relationship between the distance a between the second wall 132 and the bottom wall 21 of the guide body 13, the width B of the lower bubble passage 30, and the width D of the upper bubble passage 20 is satisfied: a is more than or equal to B is more than or equal to D. In this case, on the one hand, it is ensured that the foam passing through the lower bubble passage 30 does not have a smaller pushing force than the foam in the guide passage defined by the second wall 132 and the bottom wall 21, i.e., the pushing force does not become smaller when the foam moves from the steam inlet 101 to the lower bubble passage 30; on the other hand, it is ensured that the resistance of the lower bubble passage 30 is smaller than that of the upper bubble passage 20. The foam pushes the foam breaking member 10 to rotate, and the foam breaking structure squeezes the foam, breaking the relatively large bubbles 11 into small bubbles 12.
Preferably, the width B of the lower bubble channel 30 ranges from 3mm to 8mm. Under the condition, the smoothness of foam flow can be ensured, and a good foam breaking effect can be ensured. Specifically, when the range of B is larger, the extrusion force of the foam breaking structure to the foam is reduced, and the foam breaking effect is weakened; when the range of B is small, the resistance of the lower bubble passage 30 to the foam becomes large, which is disadvantageous for the discharge of the foam.
Preferably, as shown in fig. 1, the foam breaking member 10 is cylindrical or spherical, and the side of the guide body 13 facing the foam breaking member 10 is formed into an arc-shaped surface 133 matching the shape of the foam breaking member 10. Therefore, the whole structure is more compact, and the internal space of the steam valve is effectively saved. In addition, because the foam breaking member can be partially accommodated in the arc-shaped surface 133, the arc-shaped surface 133 can play a limiting role on the foam breaking member 10, and the rotation stability of the foam breaking member 10 is improved.
In addition, in order to facilitate cleaning or replacement of the foam breaker 10, the steam valve includes a valve seat 100 and a movable cover 230 detachably fitted over the valve seat 100, a bottom wall 21 is formed on the valve seat 100, and a top wall 23 is formed on the movable cover 230. In this case, when the foam breaker 10 needs to be cleaned, the upper cover 230 may be removed first, and both the guide body 13 and the foam breaker 10 may be removed from the foam breaker for cleaning or replacement.
In order to further improve the foam breaking efficiency of the foam breaking member, the outer circumference of the foam breaking member 10 is provided with a foam breaking structure for breaking foam. Preferably, the foam breaking structure is a protrusion provided on the rotating surface of the foam breaking member 10. Thus, when the foam breaking member 10 has a cylindrical body, the foam breaking structure may be a protrusion on the outer circumferential surface of the cylindrical body. The cylindrical foam breaking member 10 is laterally accommodated in the foam breaking chamber and is connected to the side wall 22 of the foam breaking chamber by a rotation shaft located in the axial direction of the cylinder. In order to ensure smooth rotation of the foam breaking member 10, a certain distance is provided between the bottom and top surfaces of the foam breaking member 10 and the side wall 22 of the foam breaking cavity, as long as the distance ensures that the side wall does not interfere with the rotation of the foam breaking member 10. When the foam breaking member 10 is a cylinder, the side walls of the cylinder correspond to the top wall 23 and the bottom wall 21 of the foam breaking cavity. Here, the foam breaker 10 may be spherical. Projections toward the top wall 23 and the bottom wall 21 of the foam breaking cavity are formed on the outer surface of the foam breaking member 10 in the circumferential direction. The end surface of the bulge can be any shape, so long as the bulge is beneficial to puncturing bubbles.
Preferably, the projections are a plurality of teeth with tips evenly distributed over the surface of rotation. In this way, the foam breaker 10 may be arranged in a shape similar to a gear. As the foam passes through the bubble passage between the foam breaking member 10 and the top wall 23 or the bottom wall 21 of the foam breaking chamber, the foam pushes the foam breaking member 10 to rotate, and the projections press the foam, breaking up the relatively large bubbles 11 into small bubbles 12. Further, the protrusion may be a plurality of elongated teeth parallel to each other, such that the foam breaking member 10 has a foam breaking structure matching the lengths of the foam breaking cavity and the lower air bubble passage 30, i.e., the length of the lower air bubble passage 30 extending with respect to the axial direction of the foam breaking member 10, thereby facilitating efficient extrusion of the foam.
The invention also provides an electric cooker, which comprises a cooker cover and a steam valve arranged on the cooker cover. The steam valve is arranged on the cooker cover of the electric cooker, so that on one hand, the stable pressure in the electric cooker can be kept, and the taste of food is ensured; on the other hand, the foam breaking performance of the electric rice cooker can be improved, and further, the overflow can be prevented better.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the scope of the technical concept of the present invention, and all the simple modifications belong to the protection scope of the present invention.
Moreover, any combination of the various embodiments of the invention can be made without departing from the spirit of the invention, which should also be considered as disclosed herein.
