Because the food in the cooking container is heated in a closed state, the cooking appliance further includes a steam valve 200, the steam valve 200 is disposed on the cover body 100 and used for adjusting the pressure in the cooking container, the steam valve 200 includes a valve core, a valve cover 210 and a decoration cover 220, the valve core is mainly used for adjusting the exhaust pressure, the valve cover 210 covers the valve core, a steam outlet 211 is disposed on the valve cover 210, so that the steam generated during cooking can be conveniently exhausted, and the decoration cover 220 is mounted on the outer side of the valve cover 210. According to the state shown in fig. 1, the decoration cover 220 is mounted on the valve cover 210 from top to bottom, the decoration cover 220 and the valve cover 210 are mutually extruded, a first sealing part 230 and a second sealing part 240 are formed between the decoration cover 220 and the valve cover 210 through the extrusion of the inclined surfaces of the decoration cover 220 and the valve cover 210, the first sealing part 230 and the second sealing part 240 seal the space enclosed by the decoration cover 220 and the valve cover 210, namely, after the decoration cover 220 is sleeved on the valve cover 210, a space is formed between the decoration cover 220 and the valve cover 210, and the first sealing part 230 and the second sealing part 240 are used for sealing the space, so that water vapor or rice water and the like are prevented from entering the space, and a sanitary dead space is also avoided. The first sealing portion 230 and the second sealing portion 240 are formed by mutually extruding the inclined surfaces of the valve cover 210 and the decorative cover 220 when the valve cover is installed, so that additional sealing parts such as sealing rings are not needed, materials can be saved, the production cost is reduced, the step of installing the sealing rings is omitted, and the installation process is simplified.

As shown in fig. 3 and 4, further, the decorative cover 220 includes a top wall 221 and a side wall 222 extending downward from the top wall 221, the side wall 222 extends downward from an outer edge of the top, a through hole 223 of the circuit valve cover 210 is formed in the top wall 221, that is, the top of the valve cover 210 can be exposed, so as to facilitate exhaust of steam at the top of the valve cover 210, the top of the valve cover 210 extends into the through hole 223 of the decorative cover 220, or the top of the valve cover 210 is flush with the top of the through hole 223, a first sealing portion 230 is formed between the hole wall of the through hole 223 and the valve cover 210, and the top of a space enclosed by the decorative cover 220 and the valve cover 210 is sealed; and a second sealing part 240 is formed between the lower part of the sidewall 222 and the valve cover 210 for sealing the bottom of the space enclosed by the decorative cover 220 and the valve cover 210, thereby achieving the purpose of sealing the space.

On the basis of the above scheme, the outer side of the valve cap 210 is provided with the first ring surface 212 matched with the through hole 223, the first ring surface 212 is obliquely arranged from top to bottom in the direction away from the center of the valve cap 210, the first ring surface 212 can be a circular truncated cone shape formed at the upper part of the whole valve cap 210, the circular truncated cone-shaped side wall 222 forms the first ring surface 212, or the first ring surface 212 is separately arranged at the upper part of the valve cap 210; at least part of the hole wall of the through hole 223 is inclined from top to bottom in a direction away from the center of the through hole 223, so that at least part of the hole wall of the through hole 223 and the first ring surface 212 generate an inclined surface to press to form the first sealing part 230 when the valve cover 210 and the decorative cover 220 are installed. The reason why the first ring surface 212 is inclined from top to bottom in the direction away from the center of the valve cover 210 is that when the decoration cover 220 is installed on the valve cover 210 from top to bottom, when the first sealing portion 230 is formed, a component force directed to the center of the valve cover 210 is applied to the first picture in the transverse direction, that is, the first ring surface 212 is subjected to a pressing force toward the valve cover 210, the transverse component force can be borne by the existing manufacturing material of the valve cover 210, and the existing material of the decoration cover 220 can also bear the transverse component force, so that the decoration cover 220 does not need to be modified into other materials with higher strength. If the first annular surface 212 is changed to incline from top to bottom toward the center of the valve cover 210 and the hole wall of the decorative cover 220 is adjusted accordingly, a first sealing portion 230 can be formed between the hole wall of the decorative cover 220 and the first annular surface 212 of the valve cover 210 to achieve a sealing effect, but at this time, the first annular surface 212 will receive a lateral component force in a direction away from the valve cover 210, that is, the first annular surface 212 will receive a pressing force in a direction away from the valve cover 210, which requires redesigning the structure of the position of the first annular surface 212 or considering the material strength.

Still further, part of the hole wall of the through hole 223 protrudes towards the center of the through hole 223 to be used for matching with the first ring surface 212, and the part of the hole wall protrudes to be capable of determining the contact position of the hole wall and the first ring surface 212, so that the first sealing part 230 is better formed, the formation of the through hole 223 is facilitated, and the whole through hole 223 does not need to be made into an inclined hole wall.

For the inclination angle of the first ring surface 212, it is generally required that the included angle between the first ring surface 212 and the horizontal plane is a, a is not more than 87 °, and meanwhile, the included angle between the hole wall of the through hole 223, which is matched with the first ring surface 212, and the horizontal plane is the same as the inclination angle between the first ring surface 212 and the horizontal plane, if the inclined included angle between the first ring surface 212 and the horizontal plane is greater than 87 °, when the first ring surface 212 contacts with the hole wall, the component force along the transverse direction is too small, so that sufficient extrusion force for extruding the first ring surface 212 and the hole wall cannot be generated, which easily causes the first sealing portion 230 to fail, and may also cause the first ring surface 212 and the matched hole wall to be dislocated, so that the first sealing portion 230 cannot be formed.

For the second sealing portion 240, the second annular surface 213 is disposed on the outer side of the valve cap 210 and is engaged with the sidewall 222, and the second annular surface 213 is disposed from top to bottom in an inclined manner in a direction away from the center of the valve cap 210, so that the position of the second annular surface 213 on the outer side of the entire valve cap 210 is a truncated cone shape with a small top and a large bottom, and the truncated cone-shaped sidewall 222 forms the second annular surface 213; the inner side surface of the lower part of the side wall 222 of the decoration cover 220 inclines from top to bottom in the direction away from the center of the decoration cover 220, and the inner side surface of the lower part of the side wall 222 is matched with the second annular surface 213 to form a second sealing part 240. The second annular surface 213 is disposed on the same principle as the first annular surface 212, and the second annular surface 213 is inclined in the same direction as the first annular surface 212, so that the first and second sealing

parts

230 and 240 can be installed in place at a time. The second annular surface 213 may also be modified to slope from top to bottom toward the center of the bonnet 210, as with the first annular surface 212, taking into account the structural and material requirements of the location of the second annular surface 213.

For the structure of the second sealing portion 240, it is further required that the inclination angle of the second ring surface 213 and the inner side surface of the lower portion of the sidewall 222 is B, B is less than or equal to 87 °, and also because if the inclination angle relative to the horizontal plane is greater than 87 °, the separation in the transverse direction is too small, and a sufficient pressing force for pressing the second ring surface 213 and the inner side surface of the lower portion of the sidewall 222 cannot be generated, which easily causes the second sealing portion 240 to fail, and may also cause the second ring surface 213 and the inner side surface of the lower portion of the sidewall 222 to be dislocated, so that the second sealing portion 240 cannot be formed.

On the basis of the scheme, the first supporting rib 214 and the second supporting rib 215 are arranged on the outer side of the valve cover 210, the first supporting rib 214 is positioned on the upper portion of the valve cover 210, the first supporting rib 214 is abutted to the inner side of the top wall 221 of the decorative cover 220, a supporting effect can be achieved between the upper portion of the valve cover 210 and the top wall 221 of the decorative cover 220, and a certain sealing effect can also be achieved; the second support rib 215 is provided at the bottom of the valve cover 210 and contacts the bottom of the sidewall 222 of the decorative cover 220, thereby supporting the gap between the bottom of the valve cover 210 and the bottom of the decorative cover 220 and providing a certain sealing effect. Thus, four seals are formed between the valve cover 210 and the decorative cover 220 through the above-mentioned structural design.

As shown in fig. 5 and 6, a snap 224 may be further provided on the decorative cover 220, and a snap groove 216 cooperating with the snap 224 is provided on the valve cover 210, the snap 224 is generally provided on the bottom surface of the decorative cover 220, and the snap groove 216 is a through groove and penetrates through the bottom surface of the valve cover 210, so that the decorative cover 220 and the valve cover 210 can be fitted together in advance through the snap 224 and the snap groove 216 during assembly, and sufficient pressing force is generated to form the first sealing portion 230 and the second sealing portion 240.

Of course, an outward extending brim may be provided at the bottom of the decorative cover 220, an outward extending brim may also be provided at the bottom of the valve cover 210, the cover body 100 includes the surface cover 110 and the lining cover 120, the surface cover 110 and the lining cover 120 are connected by bolts, and both the brim on the decorative cover 220 and the brim on the valve cover 210 extend between the surface cover 110 and the lining cover 120, and with the tightening of the surface cover 110 and the lining cover 120, the distance between the surface cover 110 and the lining cover 120 is gradually shortened, so as to drive the decorative cover 220 and the valve cover 210 to close and squeeze each other, and maintain the formation of the first sealing portion 230 and the second sealing portion 240.

As shown in fig. 1 and 2, during assembly, the decoration cover 220 covers the valve cover 210 from top to bottom, the decoration cover 220 and the valve cover 210 may form a pressing force by the cooperation of the snap 224 and the snap groove 216, or the decoration cover 220 and the valve cover 210 may be pressed by the surface cover 110 and the lining cover 120 of the cover body 100 when they are installed, so that the first ring surface 212 on the valve cover 210 and the hole wall of the through hole 223 on the decoration cover 220 are pressed to form the first sealing portion 230, and the second ring surface 213 on the sidewall 222 of the valve cover 210 and the lower portion of the sidewall 222 of the decoration cover 220 are pressed to form the second sealing portion 240, thereby sealing a space surrounded by the decoration cover 220 and the valve cover 210 and preventing water vapor or rice water from entering. When the decorative cover 220 and the valve cover 210 are pressed against each other, the first support rib 214 on the valve cover 210 is abutted against the top wall 221 of the decorative cover 220, the second support rib 215 on the valve cover 210 is abutted against the bottom of the decorative cover 220, the relative displacement distance between the decorative cover 220 and the valve cover 210 in the vertical direction is controlled, and the valve cover 210 and the decorative cover 220 play a supporting role simultaneously, in addition, because the first support rib 214 is abutted against the top wall 221 of the decorative cover 220, the second support rib 215 on the valve cover 210 is abutted against the bottom of the decorative cover 220, the extrusion sealing can also be formed, and therefore, the sealing performance between the valve cover 210 and the decorative cover 220 is further improved. Because the valve cover 210 and the decorative cover 220 are extruded to form sealing, a sealing ring in the conventional device is omitted, the mounting process is simplified, and the production cost is saved.
