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.

In the present invention, unless otherwise stated, terms such as "upper, lower, top, bottom" are used generally with respect to the direction in which the steam valve is installed in the rice cooker. "inner and outer" means inner and outer relative to the contour of the respective parts themselves.

The invention provides a steam valve, as shown in figures 1-5, a valve cavity 10 with a steam inlet 12 and a steam outlet 13 is formed in the steam valve, a foam breaking structure which is communicated with the steam inlet 12 and the steam outlet 13 is arranged in the valve cavity 10, the foam breaking structure comprises a foam breaking cavity 11 defined by a bottom wall 101 of the steam valve and a cover body 103 arranged on the bottom wall 101, and a foam breaking piece 14 which is arranged in the foam breaking cavity 11 and can move back and forth, the foam breaking cavity 11 is provided with a steam inlet 111 communicated with the steam inlet 12 and a steam outlet 112 communicated with the steam outlet 13, and the cover body 103 is detachably arranged on the bottom wall 101 of the steam valve. Wherein, the steam inlet of the foam breaking cavity 11 can be directly used as the steam inlet of the valve cavity 10, and the steam outlet of the foam breaking cavity 11 can also be directly used as the steam outlet of the valve cavity 10

The steam valve is used to controllably allow the discharge of steam to maintain a predetermined pressure. In general, a steam valve is installed on a heating device capable of generating steam, for example, various electric appliances for a kitchen environment, such as an electric rice cooker, etc.

After the steam valve is arranged on the cooker cover of the electric cooker, when the electric cooker is utilized to cook rice, a large amount of rice soup in the electric cooker enters the steam inlet 12 with foam under the heating action. When steam bubbles (typically a mixture of steam and steam bubbles) enter the steam inlet 12 of the steam valve, they then enter the bubble breaking structure through the steam inlet 111, and under the breaking action of the bubble breaking member 14 in the bubble breaking structure, the bubbles in the steam are broken, and the steam is allowed to be discharged to the outside along the bubble breaking cavity 11 through the steam outlet 112 and the steam outlet 13, thereby achieving a better bubble breaking effect of the steam valve.

Specifically, when steam enters the foam breaking cavity 11, the foam breaking member 14 moves under the action of the pushing force of the foam to reach a certain position of the foam breaking cavity 11, so that large foam passes through a gap (the gap is small, it can be understood that the foam breaking member 14 is in clearance fit with the peripheral wall of the foam breaking cavity 11) between the foam breaking member 14 and the peripheral wall of the foam breaking cavity 11, and meanwhile, the large foam is broken due to the rolling friction force of the foam breaking member 14, on the other hand, small foam passes through the steam outlet 112 from the gap to reach the valve cavity 10, and the small foam is broken due to the fact that the pressure in the foam breaking cavity 11 is larger than the pressure in the valve cavity 10, so that the effect of double foam breaking is achieved.

To facilitate the reciprocating movement of the foam breaking member 14 between the steam inlet 111 and the steam outlet 112, as shown in fig. 2, the foam breaking chamber 11 is arranged to extend obliquely and the steam inlet 111 is lower than the steam outlet 112. It should be understood that the steam inlet 111 is herein described below the steam outlet 112 in the state in which the steam valve is in use. As the foam breaking cavity 11 is obliquely arranged in an extending way, the reflux effect of rice soup is improved. The arrangement is such that the foam breaking cavity 11 is formed as an inclined channel, the foam breaking piece 14 moves from the steam inlet 111 to the steam outlet 112 under the action of the thrust of the steam foam, and meanwhile, the foam breaking piece 14 moves along the inclined foam breaking cavity 11 towards the steam inlet 111 under the action of the gravity of the foam breaking piece 14, and in the process, the foam breaking piece 14 moves in the foam breaking cavity 11 under the combined action of the thrust of the steam foam and the gravity of the foam breaking piece 14, such as sliding, rolling or swinging, so that the extrusion and the impact of the steam foam are realized to eliminate the steam foam. The foam breaking member 14 is preferably a rolling member including a sphere or a cylinder in view of both ease of manufacture and moving effect.

The foam breaker 14 may be provided in various forms according to the invention. For example, the foam breaking member 14 may have a roller structure capable of rolling along the extending direction of the foam breaking cavity 11; also for example, the foam breaking member 14 is a piston structure cooperating with the foam breaking chamber 11, which is capable of sliding within the foam breaking chamber 11.

In the embodiment shown in fig. 2, the foam breaking member 14 is a rolling member comprising a sphere or cylinder. The rolling element is capable of rolling along the extension direction of the breaking cavity 11. The rolling member increases the contact area of the bubble breaking member 14 with the steam bubbles, thereby facilitating breaking of the bubbles therein. Preferably, the rolling elements may be solid or hollow to form a roller. In addition, the rolling element can be stainless steel, aluminum, titanium alloy or stainless iron or ceramic body. In order to reduce noise, further, the outer circumferential surface of the rolling element is wrapped with an elastic layer or an elastic sleeve, such as silica gel. Alternatively, the rolling element can be directly formed into a plastic body, and the single material has a simple structure, and is convenient for rolling while reducing noise.

According to the invention, the foam breaking cavity 11 may be formed in a closed manner or may be formed in a manner as shown in fig. 1. As shown in fig. 1, the bottom wall 101 of the steam valve is provided with a pair of side walls 102 extending toward the valve chamber 10 at a distance from each other, a lid 103 is mounted on the pair of side walls 102, and the bottom wall 101, the pair of side walls 102, and the lid 103 define a foam breaking chamber 11. The cover 103 is detachably engaged with the pair of side walls 102 to facilitate the installation and replacement of the foam breaking member 14 in the foam breaking chamber 11.

The bottom wall 101 of the steam valve constitutes the bottom wall of the bubble breaking chamber 11, on which a pair of spaced side walls 102 extending towards the upper part (orientation shown in fig. 1) are provided to form the side walls of the bubble breaking chamber 11. A cover 103 is mounted on the side walls to form a top wall of the breaking cavity 11. Of course, the present application is not limited thereto, and for example, the assembled foam breaking chamber may be mounted to a predetermined position in the valve chamber 10.

Preferably, within the foam breaking cavity 11, the bottom wall 101 and/or the cover 103 guides the foam breaking element 14 to roll along the foam breaking cavity 11 by means of the guiding mechanism 17.

Specifically, as shown in fig. 1, the guide mechanism 17 preferably includes a guide flange 172 and a guide groove 171 that is clearance-fitted with the guide flange 172, wherein: a guide flange 172 is formed on the outer peripheral surface of the rolling member, and a guide groove 171 is formed on the cover 103 and/or the bottom wall 101; or the guide groove 171 is formed on the outer peripheral surface of the rolling member, and the guide flange 172 is formed on the cover 103 and/or the bottom wall 101. The guide groove 171 serves to limit the guide flange 172 and at the same time provide a path of movement for the foam breaker 14.

In the present invention, it is preferable that a guide flange 172 is formed on the outer peripheral surface of the rolling element, a guide groove 171 is formed on the lid 103 and the bottom wall 101, and the guide flange 172 is fitted into the guide groove 171 to reciprocate the rolling element up and down along the guide groove 171. The specific process of rolling and breaking bubbles of the rolling piece is as follows: when the steam pressure of the inner pot is high, the rolling element can be pushed to roll towards the top end of the foam breaking cavity 11 along the guide groove 171, so that the steam and the foam enter the foam breaking cavity 11 through the steam inlet 111, and meanwhile, the rolling element rolls towards the steam inlet of the foam breaking cavity 11 along the guide groove 171 under the action of gravity, so that the rolling element continuously extrudes the foam in the process of up-and-down reciprocating rolling, and accumulated water formed directly flows back along the bottom wall 101.

Preferably, there is a gap between the rolling element and the bottom wall 101 of the breaking cavity 11; and/or a gap between the rolling member and the inner surface of the cover 103; and/or a gap between the rolling members and the inner surfaces of the pair of side walls 102. These clearances on the one hand reduce the friction between the foam breaking member 14 and the inner wall of the foam breaking cavity 11, thus improving the service life of the foam breaking member 14; on the other hand, the steam bubbles can be further allowed to pass through, and the steam bubbles can be further extruded at the gap, so that the bubble breaking efficiency is improved.

According to the present invention, in order to facilitate solid particles in rice soup overflowed from the steam inlet 12 to fall into the rice cooker under self gravity, the steam inlet 12 is disposed downward. This arrangement causes the steam inlet 12 to face the direction of movement of the steam bubbles so that the steam bubbles can enter the steam inlet 12 directly during the ascent, which results in a smoother entering of the steam bubbles, thereby improving the intake performance of the steam valve. At the same time, the arrangement is further beneficial to the backflow of the liquid.

In addition, a limiting rib 18 is formed on the bottom wall 101 or the cover 103, which is located outside the foam breaking cavity 11 and is adjacent to the steam outlet 112, so as to prevent the rolling element from sliding out of the foam breaking cavity 11. The specific form of the limiting rib 18 may be a sheet structure extending from the bottom wall 101 to the valve cavity 10. The stop rib 18 is used to block the foam breaking member 14 to prevent the foam breaking member 14 from moving out of the foam breaking cavity 11 during movement. Of course, the stop rib 18 is preferably arranged so as not to interfere with the backflow of liquid.

The arrangement of the foam breaking chamber 11 is described in detail below.

Referring to fig. 1, the cover 103 is preferably removably attached to the pair of side walls 102. To achieve such a detachable connection, the preferred structure of the invention is: the cover 103 includes a cover plate 1031 and a pair of lugs 1032 extending from the cover plate 1031 toward the bottom wall 101 spaced apart from each other, with inner sides of the pair of lugs 1032 being snap-fitted to each other with outer sides of the pair of side walls 102 by a snap-fit structure. Of course, the connection is not limited to snap-fit connection, but may be threaded connection, pin connection, etc., and any structure that enables the removable connection described above is within the scope of the present invention.

Preferably, the snap structure includes a protrusion 15 and a recess 16 snap-fitted to each other, wherein the protrusion 15 is formed on one of the inner sides of the pair of lugs 1032 and the outer sides of the pair of side walls 102; a recess is formed on the other of the inner sides of the pair of lugs 1032 and the outer sides of the pair of side walls 102. The protrusion 15 and the recess 16 may be mounted on only one side, preferably on both sides.

For convenience of installation and operation, the protrusions 15 are in the form of a bar and are formed on the inner sides of the pair of lugs 1032, and the recesses 16 are formed on the outer sides of the pair of side walls 102 and extend to the ends of the side walls 102 in the direction of the steam outlet 112 to form sliding passages of the protrusions 15 of the cover 103, the ends of the side walls 102 being formed as openings of the sliding passages, preferably in the form of horns, for guiding the installation of the protrusions 15. In addition, the protrusion 15 is also formed with a stopper surface 151 that prevents it from coming off from the recess 16. The stop surface 151 is flat or formed with a chamfer, and in the present invention, preferably, the stop surface 151 is formed with a chamfer and the recess 16 is also formed with a chamfer, so that the upper end of the chamfer of the stop surface 151 is staggered with the lower end of the chamfer of the recess 16, and the stop surface is easy to be buckled when being assembled and disassembled.

In order to strengthen the engagement of the lugs 1032 with the side walls 102 and prevent disengagement thereof, the present invention also cooperates with the outer sides of the pair of side walls 102 at the inner sides of the pair of lugs 1032 via a spacing structure. The limit structure preferably includes a pair of stop ribs 161 and a pair of limit projections 162, wherein the pair of stop ribs 161 are respectively formed in the concave portions 16 on the outer sides of the pair of side walls 102; a pair of stopper protrusions 162 are protrusively formed on inner sides of the pair of lugs 1032 and spaced apart from the corresponding protrusions 15, and after the cover 103 is slid into the sliding channel, the pair of stopper ribs 161 are restricted between the corresponding stopper protrusions 162 and the protrusions 15 adjacent thereto. The limit bump 162 is also formed with a chamfer. In order to prevent the protrusion 15 from being separated from the recess 16 during assembly, the height of the stopper rib 161 is smaller than the depth of the recess 16.

In order to facilitate the assembly and disassembly of the cover 103 and the side wall 102, a plurality of protrusions 1033 are formed on the outer surface of the cover 103 and arranged along the length direction of the cover 103.

In the present invention, the cover 103 and the side arm 102 may be mounted by sliding or may be directly fastened (see fig. 4 and 5). When the cover body 103 is installed, the front end of the cover body 103 is overlapped with the upper surface of the side wall 102, and the push protrusion 1033 pushes the cover body 103 inwards along the direction of the side wall 102, so that the limiting piece 16 and the protruding part 15 slide into the concave part 16 and are buckled with the concave part 16; it is also possible to press the cover 103 down on the side walls 102 so that a pair of lugs 1032 on both sides of the cover 103 are located on the outer sides of the pair of side walls 102 and the inner sides of the lugs 1032 are snap-fitted with the outer sides of the corresponding side walls 102 by a snap-fit structure.
