Cooking appliance 100 also includes a steam valve assembly 40 according to the present application. The steam valve assembly 40 is detachably connected to the cover assembly 20. The steam valve assembly 40 serves at least to release steam generated in the cooking space 12 due to cooking heating.

As shown in fig. 2, the steam valve assembly 40 includes a first steam flow-blocking condensing chamber 41A, a second steam flow-blocking condensing chamber 41B, a condensed water accommodating portion WR, an air outlet 51, and a heat conducting portion HC. The vapor valve assembly 40 is configured to allow the first vapor-choked flow condensing chamber 41A and the second vapor-choked flow condensing chamber 41B to communicate. Wherein the first steam blocking condensing chamber 41A is for communicating with the cooking space 12 of the cooking appliance 100 to allow steam generated by cooking heating to enter the steam valve assembly 40. The condensed water accommodating portion WR is disposed in the first steam choked flow condensing chamber 41A for storing condensed water (the steam enters the steam valve assembly 40 to dissipate heat and cool down to form condensed water). The air outlet 51 communicates with the second vapor-blocking condensing chamber 41B for releasing vapor. The heat conductive part HC is connected to the condensed water accommodating part WR for conducting heat to heat the condensed water.

Specifically, the steam valve assembly 40 includes a steam valve housing assembly 41 and a partition assembly 60. The steam valve housing assembly 41 is for detachable connection to the cover assembly 20 of the cooking appliance 100. The steam valve housing assembly 41 encloses a steam valve cavity 41E. The partition assembly 60 is disposed in the steam valve chamber 41E for partitioning the steam valve chamber 41E into a first steam-flow-blocking condensing chamber 41A and a second steam-flow-blocking condensing chamber 41B. Partition assembly 60 is configured to allow first vapor-flow-blocking condensing chamber 41A to communicate with second vapor-flow-blocking condensing chamber 41B.

The heat generating member 26 enables condensed water in the steam valve assembly 40 (specifically, the steam valve chamber 41E) to be heated. For example, in the heat-preserving process of the cooking process, the control device controls the heating element 26 to work so that condensed water in the steam valve cavity 41E boils, and steam generated by the condensed water is sprayed back into the cooking space 12 from the air inlet pipe outlet 59 through the air inlet channel 57A and the air inlet pipe inlet 58, so as to achieve the purpose of preserving moisture of rice. According to the present application, the cooking appliance 100 does not need to provide an additional water supply part, and completely utilizes condensed water formed by steam generated from cooking water to generate steam, and the steam valve assembly 40 has a simple structure, can be used for releasing steam and generating steam at different cooking stages, and improves user experience while reducing costs.

Specifically, as shown in fig. 2, the cover assembly 20 includes a face cover assembly 21 and a liner cover assembly 22. In general, the face cover assembly 21 forms the outer shell of the cover assembly 20, with the liner cover assembly 22 being covered by the face cover assembly 21 from above.

Preferably, the heat generating element 26 is located on the upper surface of the liner cap assembly 22, i.e., the side of the liner cap assembly 22 that faces the face cap assembly 21. The liner cap assembly 22 includes a second insulation 32. The heat generating element 26 is attached to the insulation at its lower surface such that the heat generating element 26 is separated from other components of the liner cap assembly 22 by a second insulation 32. So that other portions of the liner cap assembly 22 may be protected from high temperatures. The second heat insulator 32 is made of, for example, a silicone material. As shown, the first seal 31 is also attached to the heat generating element 26 (e.g., to the upper surface of the heat generating element 26) such that the first seal 31 is located between the heat generating element 26 and the bottom wall of the face cover valve spool 23. Therefore, the first sealing member 31 also has a heat insulating effect, which makes the heat generating member 26 not directly contact with the cover assembly 21, and prevents the cover assembly 21 from being affected by high temperature.

When the steam valve assembly 40 is connected to the cover assembly 20, the heat conducting portion HC contacts the heat generating member 26.

In the illustrated embodiment, the valve seat side wall 46 is also the side wall of the steam valve chamber 41E.

Preferably, the steam valve housing assembly 41 is generally configured in a radiation symmetrical shape, such as a shape consisting of a cylinder and/or a truncated cone, except for a portion of the air inlet tube 57. Alternatively, the valve seat body 44 is generally configured in a radiation-symmetrical shape, such as a shape consisting of a cylinder and/or a truncated cone. Preferably, the intake pipe 57 is configured in a cylindrical shape.

Preferably, a portion of the valve seat side wall 46 forms a portion of the wall of the air inlet tube 57. Accordingly, the intake pipe 57 is disposed proximate the valve seat side wall 46 such that it is positioned opposite the edge of the first vapor choked flow condensing chamber 41A, facilitating the provision of the heat conducting portion HC and increasing the area of the heat conducting portion HC.

Preferably, the valve cover 42 is sealingly connected to the valve seat sidewall 46 at the top of the valve seat sidewall 46. For example. The lower surface of the valve cover 42 is provided with an annular valve cover recess 47 (see fig. 6), and the steam valve assembly 40 further comprises a seventh sealing ring 37, the seventh sealing ring 37 being fitted in the valve cover recess 47 for contacting the top surface of the valve seat side wall 46. The seventh seal ring 37 is made of, for example, a silicone material. Of course, the valve cover 42 and the valve seat 43 may be sealingly connected in other manners.

Preferably, the valve cover 42 is detachably connected to the valve seat 43. The valve cover 42 is detachably connected to the valve seat 43 by, for example, a screw pair or a snap.

Preferably, the heat conducting portion HC is provided to the valve seat bottom wall 45. For example, the entire valve seat 43, or the entire valve seat body 44, or the entire valve seat bottom wall 45 may be made of a metal material (or other material having good heat conductive properties) to form the heat conductive portion HC.

Alternatively, the steam valve assembly 40 further includes a heat conducting member 56 forming the heat conducting portion HC. The heat conductive member 56 is hermetically connected to the steam valve chamber 41E. When the steam valve assembly 40 is connected to the cover assembly 20, the heat conductive member 56 contacts the heat generating member 26 of the cover assembly 20, thereby heating the condensed water in the steam valve chamber 41E. Preferably, the thermally conductive member 56 comprises a metallic material, such as aluminum. For example, the valve seat body 44 is provided with a valve seat through hole 52, and the heat conductive member 56 extends through the valve seat through hole 52 and is connected with the valve seat through hole 52 in a sealing manner in the circumferential direction, so that one end of the heat conductive member 56 is used to contact the heat generating member 26 and the other end is used to contact condensed water in the steam valve chamber 41E.

Preferably, the valve seat through-hole 52 is provided to the valve seat bottom wall 45. Preferably, the valve seat bottom wall 45 includes a bottom wall body 49 and a recess 48. Wherein the valve seat side wall 46 is connected to the outer periphery of the bottom wall body 49. The lower recess 48 is recessed downward from the bottom wall body 49. Preferably, a valve seat through hole 52 is provided to the lower recess 48.

Preferably, as shown in fig. 3, the outer circumferential surface of the heat conductive member 56 is provided with a heat conductive member groove 55, and the steam valve assembly 40 further includes a fifth seal ring 35, the fifth seal ring 35 being fitted in the heat conductive member groove 55 for contacting the inner surface of the valve seat through hole 52. The fifth seal ring 35 is made of, for example, a silicone material. The fifth seal ring 35 also serves to insulate against heat and prevent the valve seat through-hole 52 from being deformed after being subjected to high temperature. Of course, the heat conducting member 56 and the valve seat through hole 52 may be hermetically connected in other manners.

The separation assembly 60 is disposed in the steam valve cavity 41E and is in sealing connection with the steam valve housing assembly 41, at least for separating the steam valve cavity 41E into a first steam flow blocking condensing cavity 41A and a second steam flow blocking condensing cavity 41B. Wherein the air inlet pipe outlet 59 is arranged in the first steam flow blocking condensing cavity 41A, the air outlet 51 is arranged to a part of the steam valve housing assembly 41 for enclosing the second steam flow blocking condensing cavity 41B, and the air inlet pipe outlet 59 is higher than the lowest point of the first steam flow blocking condensing cavity 41A. Partition assembly 60 is configured to allow first vapor-flow-blocking condensing chamber 41A to communicate with second vapor-flow-blocking condensing chamber 41B. For example, the outer peripheral surface of the partition assembly 60 is provided with a partition groove 66 (see fig. 6), and the steam valve assembly 40 further includes a sixth seal ring 36, the sixth seal ring 36 being fitted in the partition groove 66 for contacting the inner surface of the steam valve chamber 41E. The sixth seal ring 36 is made of, for example, a silicone material. Of course, the partition assembly 60 and the inner surface of the steam valve chamber 41E may be sealingly connected in other manners.

Preferably, the partition assembly 60 includes a portion extending at a first angle alpha from the horizontal, wherein 3 deg. to 90 deg.. More preferably, 5.ltoreq.alpha.ltoreq.60.

The purpose of separating the steam valve cavity 41E into the first steam flow-blocking condensing cavity 41A and the second steam flow-blocking condensing cavity 41B is to prevent steam generated by condensed water in the first steam flow-blocking condensing cavity 41A from flowing toward the second steam flow-blocking condensing cavity 41B as much as possible (i.e. from flowing away from the air outlet 51) when the steam valve cavity 41E is heated, so that the steam can be returned to the cooking space 12 through the air inlet pipe outlet 59, and thus, sufficient moisture-preserving steam can be ensured to be obtained in the cooking space 12. The separation assembly 60 is inclined with respect to the horizontal direction, so that condensed water in the second vapor block-flow condensing chamber 41B is facilitated to flow back into the first vapor block-flow condensing chamber 41A.

To achieve this, in the embodiment shown in fig. 3, the bottom of the partition assembly 60 is provided with a communication portion 63 allowing the passage of fluid, so that the bottom of the first vapor block condensation chamber 41A communicates with the bottom of the second vapor block condensation chamber 41B, or so that the first vapor block condensation chamber 41A communicates with the second vapor block condensation chamber 41B at the bottom. When the condensed water is stored in the steam valve chamber 41E, the condensed water may go beyond the communication portion 63, that is, the communication portion 63 is water-sealed. At this time, if the steam generated from the condensed water is to enter the second steam choked flow condensing chamber 41B, the resistance of the water seal must be overcome. It will be appreciated that the water seal causes a resistance greater than the resistance to the vapor exiting the inlet pipe outlet 59, so that a substantial portion of the vapor exits the inlet pipe outlet 59 without entering the second vapor block condensation chamber 41B.

During cooking heating, the amount of steam generated by the cooking water (hereinafter, simply referred to as cooking steam) in the cooking space 12 is much larger than the amount of steam generated by the condensed water (hereinafter, simply referred to as moisturizing steam). A large amount of the cooking steam is concentrated to the relatively narrow intake passage 57A, so that the pressure of the cooking steam increases. A large amount of high-pressure cooking steam has the ability to overcome the resistance of the water seal, and thus can enter the second steam choked flow condensing chamber 41B and be discharged without causing a safety problem. Therefore, a person skilled in the art can design a suitable water sealing resistance through experiments and calculation, so that the cooking steam can overcome the water sealing resistance, and the moisture-keeping steam cannot overcome the water sealing resistance.

Preferably, the uppermost edge of the communication portion 63 is spaced from the bottom surface of the first vapor choked flow condensing chamber 41A by a distance of 0.3 to 3mm. Further preferably, the uppermost edge of the communication portion 63 is spaced from the bottom surface of the first vapor choked flow condensing chamber 41A by a distance of 0.5 to 1.5mm. Preferably, the area of the communication portion 63 is 10% to 300% of the sectional area of the intake pipe outlet 59. Further preferably, the area of the communication portion 63 is 90% to 150% of the sectional area of the intake pipe outlet 59. Here, the cross-sectional area of the intake pipe outlet 59 refers to the cross-sectional area of the intake pipe outlet 59 in a cross-section perpendicular to the flow direction of the steam.

Specifically, as shown in fig. 3, the partition assembly 60 includes a first partition 61. The first partition 61 is disposed in the steam valve chamber 41E and is sealingly connected to an inner surface of the steam valve chamber 41E for constituting at least a portion of a boundary between the first steam-blocking condensing chamber 41A and the second steam-blocking condensing chamber 41B. The first partition 61 is provided with a first through hole 64 for communicating portions of the steam valve chamber 41E respectively located on both sides of the first partition 61. The first partition 61 extends in a direction non-parallel to the vertical direction. For example, at least part of the first partition 61 extends at a first angle a to the horizontal direction. All of the first partitions 61 extend at a first angle a from the horizontal direction. The first partition 61 is located above the intake pipe outlet 59. The steam valve assembly 40 further includes a second divider 62, the second divider 62 extending in a direction non-parallel to the horizontal direction. The top of the second partition 62 is hermetically connected to the lower surface of the first partition 61, and the side of the second partition 62 is hermetically connected to the inner surface of the steam valve chamber 41E, and the bottom of the second partition 62 is provided with a communication portion 63 (see fig. 4) so that portions of the steam valve chamber 41E respectively located on both sides of the second partition 62 communicate with each other. Wherein the second partition 62 is located between the intake pipe outlet 59 and the first through hole 64 in the horizontal direction or the vertical direction. Thus, the portion of the steam valve chamber 41E located below the first partition 61 and on the side of the second partition 62 facing the intake pipe outlet 59 is the first steam-blocking condensing chamber 41A, and the portion of the steam valve chamber 41E located above the first partition 61 (the fourth steam-blocking condensing chamber 41D) and the portion located below the first partition 61 and on the side of the second partition 62 facing away from the intake pipe outlet 59 (the third steam-blocking condensing chamber 41C) are the second steam-blocking condensing chamber 41B.

Preferably, the first partition 61 extends in a direction not parallel to the horizontal direction, so that condensed water in the fourth steam flow-blocking condensing chamber 41D can flow back to the first steam flow-blocking condensing chamber 41A to reserve a sufficient source of condensed water for the moisturizing steam. Preferably the second partition 62 extends in a vertical direction. It is understood that the second partition 62 extends in the vertical direction under the condition that the above-described limitation of the distance of the uppermost edge of the communication portion 63 from the bottom surface of the first vapor block condensation chamber 41A is satisfied, which is advantageous in saving the material of the second partition 62.

Preferably, the heat conducting portion HC is located on the same side of the second partition 62 as the intake pipe 57. For example, a heat conducting portion HC (e.g., the heat conducting member 56) is located between the second partition 62 and the intake pipe 57 to improve the efficiency with which the heat conducting portion HC heats the condensed water in the first vapor choked flow condensing chamber 41A.

As shown in fig. 5, preferably, the inner surface of the steam valve chamber 41E (specifically, the inner surface of the valve seat 43) is provided with ribs 50 for supporting the first partition 61, so that the first partition 61 is removably provided in the steam valve chamber 41E. When the first partition 61 is placed in the steam valve chamber 41E, the bead 50 supports the lower surface of the first partition 61. For example, the inner surface of the valve seat side wall 46 is provided with a plurality of ribs 50A, 50B, 50C, 50D, 50E and 50F. The plurality of ribs 50 are symmetrically distributed so that the first separator 61 can be stably supported.

Preferably, as shown in fig. 3, the first partition 61 includes a partition portion 61A and a contact portion 61B. Wherein the partition 61A is for constituting at least part of a boundary between the first vapor block condensation chamber 41A and the second vapor block condensation chamber 41B, and the first through hole 64 is provided to the partition 61A. The contact portion 61B extends upward from the outer peripheral edge of the partition portion 61A and forms a complete structure in the circumferential direction (e.g., forms a complete cylindrical shape) for sealingly contacting the inner wall of the steam valve chamber 41E (e.g., the inner surface of the valve seat side wall 46). Preferably, a partition groove 66 (see fig. 6) is provided at the outer peripheral surface of the contact portion 61B for accommodating the sixth seal ring 36 so that the first partition 61 is in sealing contact with the steam valve chamber 41E.

As shown in fig. 4, at least part of the bottom edge of the second partition 62 does not contact the bottom wall of the first vapor-choked flow condensing chamber 41A, that is, a gap is provided between the bottom edge of the second partition 62 and the bottom wall (e.g., the valve seat bottom wall 45) of the first vapor-choked flow condensing chamber 41A to form the communicating portion 63. At this time, the uppermost edge of the bottom edge of the second separator 62, that is, the uppermost edge of the communication portion 63, the cross-sectional area of the gap in a cross section perpendicular to the steam flow direction is the area of the communication portion 63. Alternatively, in an embodiment not shown in the present application, the bottom of the second partition 62 is provided with at least one through hole to form the communication portion 63. At this time, the highest of the uppermost edges of the through holes in the at least one through hole is the uppermost edge of the communication portion 63, and the sum of the cross-sectional areas of all the through holes is the area of the communication portion 63. Of course, the communication portion 63 may be formed by using a slit and a through hole at the same time.

As shown in fig. 4, a second partition 62 may be provided to an inner wall of the first vapor choked flow condensing chamber 41A. At this time, the top edge of the second partition 62 contacts the lower surface of the first partition 61 through a sealing material (e.g., silicone). Alternatively, the lower surface of the first divider member is provided with a slot for receiving the top edge of the second divider member 62. The second partition 62 may also be provided to the lower surface of the first partition 61 (i.e., the first partition 61 is formed integrally with the second partition 62). At this time, the side of the second partition 62 contacts the inner surface of the steam valve chamber 41E through a sealing material (e.g., silicone), or the inner surface of the steam valve chamber 41E is provided with a groove for receiving the side of the second partition 62. For example, as shown in fig. 5, ribs 50B and 50C form a groove for receiving one side of the second partition 62, and ribs 50E and 50F form a groove for receiving the other side of the second partition 62.

As can be seen from fig. 5 and 3, at the end of the intake pipe 57 where the intake pipe outlet 59 is provided, the pipe wall of the intake pipe 57 includes a portion 59A extending radially toward the intake passage 57A, the radial pipe wall 59A being such that the cross-sectional area of the intake pipe inlet 58 is larger than the cross-sectional area of the intake pipe outlet 59. Wherein the sectional area refers to a sectional area in a section perpendicular to a flow direction of steam. In this way, the cooking steam is introduced from the larger inlet and discharged from the smaller outlet, so that the pressure, speed, etc. of the steam discharge increases. This corresponds to increasing the pressure in the first vapor choked flow condensing chamber 41A, creating an obstruction to the entry of cooking vapor into the vapor valve assembly 40. Thus, the cooking steam in the cooking space 12 is not easily and largely gushed into the steam valve assembly 40 at the same time to cause overflow.

As shown in fig. 3, in order to maximize the formation of condensed water from the cooking steam entering the first steam-blocking condensing chamber 41A, the steam valve assembly 40 further includes at least one first condensing baffle 53, and the first condensing baffle 53 is disposed in the first steam-blocking condensing chamber 41A. The first condensation baffle 53 is used to block and condense the vapor flowing through the first vapor block condensation chamber 41A. The first condensation baffle 53 is configured to allow vapor to enter the first vapor-flow-blocking condensation chamber 41A from the intake pipe outlet 59 and then the second vapor-flow-blocking condensation chamber 41B. That is, the first condensation baffle 53 does not affect the connectivity of the vapor pathway from the inlet pipe outlet 59 to the second vapor-flow-blocking condensation chamber 41B, but rather blocks vapor only at a localized location in the first vapor-flow-blocking condensation chamber 41A. Thus, the first condensation baffle 53 functions to dissipate heat and condense so that the steam in the first steam choked flow condensing chamber 41A forms more condensed water. In order not to affect connectivity of the steam passage in the first steam-blocking condensing chamber 41A, for example, at least one edge of the first condensing baffle 53 is spaced from an inner wall of the first steam-blocking condensing chamber 41A, or a through hole is provided on the first condensing baffle 53.

Preferably, the first condensation baffle 53 is connected to the first partition 61 below (lower surface of) the first partition 61 with a gap from the bottom surface of the first vapor choked flow condensing chamber 41A. So that the first condensation baffle 53 is formed integrally with the first partition 61. Preferably, at least one of the first condensation baffles 53 is located between the inlet pipe outlet 59 and the first through hole 64 in a horizontal direction or a vertical direction. Accordingly, the first condensation baffle 53 can sufficiently contact the cooking steam flowing in from the steam inlet (the intake pipe outlet 59) of the first steam blocking condensing chamber 41A in the first steam blocking condensing chamber 41A. Preferably, the first condensation baffle 53 extends in a vertical direction.

Similarly, in order to maximize the formation of condensate from the cooking steam entering the second steam-blocking condensing chamber 41B, the steam valve assembly 40 further includes at least one second condensing baffle 54, the second condensing baffle 54 being disposed within the second steam-blocking condensing chamber 41B. The second condensation baffle 54 is used for blocking and condensing the steam flowing through the second steam blocking condensation chamber 41B. The second condensation baffle 54 is configured to allow vapor from the first vapor-choked flow condensation chamber 41A to enter the second vapor-choked flow condensation chamber 41B and then to exit the air outlet 51. That is, the second condensation baffle 54 does not affect the connectivity of the vapor pathway from the first vapor-choked condensation chamber 41A to the air outlet 51, but rather blocks vapor only at a localized location in the second vapor-choked condensation chamber 41B. Thus, the second condensation baffle 54 functions to dissipate heat and condense so that the steam in the second steam-blocking condensing chamber 41B forms more condensed water. In order not to affect connectivity of the steam passage in the second steam-blocking condensing chamber 41B, for example, at least one edge of the second condensing baffle 54 is spaced from an inner wall of the second steam-blocking condensing chamber 41B, or a through hole is provided on the second condensing baffle 54.

The second condensation baffle 54 may be provided to the first partition 61, or may be provided to the steam valve housing assembly 41. For example, the second condensation baffle 54 is provided to the upper surface of the first partition 61 such that the second condensation baffle 54 is formed integrally with the first partition 61. For example, the second condensation baffle 54 is provided to the lower surface of the valve cover 42 such that the second condensation baffle 54 is formed integrally with the valve cover 42. Of course, the first partition 61 and the valve cover 42 may be provided with the second condensation barrier 54 at the same time.

The first condensation baffle 53 may be configured as a flat plate, or a C-shaped plate, or a W-shaped plate, or an S-shaped plate, or a combination of flat and arcuate plates. The second condensation baffle 54 may also be configured as a flat plate, or a C-plate, or a W-plate, or an S-plate, or a combination of flat and arcuate plates.

Preferably, at least one of the second condensation baffles 54 is located between the air outlet 51 and the first through hole 64 in a horizontal direction or a vertical direction. Thus, the cooking steam entering the second steam blocking condensing chamber 41B may sufficiently contact the second condensing baffle 54 to form condensed water as much as possible. Preferably, the second condensation baffle 54 extends in a vertical direction.

It will be appreciated that the second condensation baffle 54 is also configured such that the interior of the second vapor-flow-blocking condensation chamber 41B communicates at the bottom to allow condensed water in the second vapor-flow-blocking condensation chamber 41B to flow out of the second vapor-flow-blocking condensation chamber 41B (e.g., to allow condensed water in the fourth vapor-flow-blocking condensation chamber 41D to flow back to the third vapor-flow-blocking condensation chamber 41C through the first through hole 64 and then to flow back to the first vapor-flow-blocking condensation chamber 41A through the communication portion 63).

It is understood that the first partition 61 is preferably configured to extend obliquely with respect to the horizontal direction, thereby facilitating the flow of condensed water on the upper surface of the first partition 61. Preferably, the first through hole 64 is provided at a side of the first partition 61 where the position is lower. In other words, it is preferable that the first partition 61 is configured to extend obliquely with respect to the horizontal direction such that the bottom peripheral edge of the first partition 61 has the first position point 61C at which the position is lowest and the second position point 61D at which the position is highest, and the first through hole 64 is closer to the first position point 61C than to the second position point 61D.

Preferably, the heat conducting member 56 is detachably connected to the valve seat 43. For example, as shown in fig. 3, the heat conductive member 56 includes a first heat conductive portion 56A and a second heat conductive portion 56B, the first heat conductive portion 56A being detachably connected to the second heat conductive portion 56B. Preferably, the first heat conductive portion 56A and the second heat conductive portion 56B are connected by a screw pair. For example, the first and second heat conductive portions 56A and 56B are provided with mating female and male threads, respectively, so that the first and second heat conductive portions 56A and 56B are threadably connected. Alternatively, the first heat conduction portion 56A and the second heat conduction portion 56B are each provided with a corresponding screw hole, and the two are connected by connecting the corresponding screw holes of the two by the same bolt. Alternatively, one of the first heat conduction portion 56A and the second heat conduction portion 56B may be provided with a through hole, and the other may be provided with a corresponding screw hole, and the same bolt may be inserted into the screw hole after passing through the through hole, so that the first heat conduction portion 56A and the second heat conduction portion 56B may be connected.

When the heat conducting portion is mounted to the valve seat 43, at least a portion of the first heat conducting portion 56A is located outside the valve seat 43 (i.e., outside the first vapor-flow-blocking condensing chamber 41A) for receiving a heat source (e.g., the heat generating element 26), and at least a portion of the second heat conducting portion 56B is located inside the valve seat 43 (i.e., inside the first vapor-flow-blocking condensing chamber 41A) for transferring heat to the condensed water. At least part of the first heat conducting portion 56A in the portion located outside the valve seat 43 has a radial dimension larger than the aperture of the valve seat through hole 52, and at least part of the second heat conducting portion 56B in the portion located inside the valve seat 43 has a radial dimension larger than the aperture of the valve seat through hole 52, so that the heat conducting member groove 55 is formed in the outer peripheral surface of the heat conducting member 56. The heat conductive member groove 55 serves to accommodate the fifth seal ring 35 and also serves to surround the valve seat bottom wall 45 at the valve seat through hole 52 so that the heat conductive member 56 does not come off from the valve seat 43. When the heat conductive member 56 is mounted, the first heat conductive portion 56A and the second heat conductive portion 56B are inserted into the valve seat through hole 52 along the axis from both sides of the valve seat through hole 52, respectively, and then the first heat conductive portion 56A and the second heat conductive portion 56B are firmly connected.

It will be appreciated that the cooking steam, when entering the steam cavity 41E, may carry foam, rice soup, etc., which may cause foreign matter to accumulate inside the steam cavity 41E. Preferably, as shown in fig. 6, the steam valve assembly 40 is configured to be detachably assembled by the valve cover 42, the seventh seal ring 37, the partition assembly 60, the sixth seal ring 36, the valve seat 43, the second heat conducting portion 56B, the fifth seal ring 35, the first heat conducting portion 56A, and the like. The user can easily disassemble and assemble the steam valve assembly 40 so that the steam valve assembly 40 can be cleaned.

As shown in fig. 6, preferably, the lower surface of the first partition 61 is provided with a second partition 62 and a first condensation baffle 53; the upper surface of the first partition 61 is provided with the second condensation baffle 54, that is, the first partition 61, the second partition 62, and the first condensation baffle 53 are formed as one body. Preferably, the lower surface of the valve cover 42 is also provided with a second condensation baffle 54.

As shown in fig. 7, the cooking steam is discharged from the cooking space 12 through a path of the intake pipe inlet 58, the intake passage 57A, the intake pipe outlet 59, the first steam flow-blocking condensing chamber 41A, the second steam flow-blocking condensing chamber 41B, and the air outlet 51. Baffles in the first vapor block condensation chamber 41A and the second vapor block condensation chamber 41B serve to form sufficient condensed water. The moisture vapor formed by the heating of the condensed water is not likely to enter the second vapor choked flow condensing chamber 41B, and thus is returned to the cooking space 12 via the path of the intake pipe outlet 59→the intake passage 57a→the intake pipe inlet 58.

As described above, the condensed water in the first steam choked flow condensing chamber 41A is used to form the moisturizing steam in the warming process of the cooking process. Accordingly, the cooking appliance 100 is configured such that the control device controls the heat generating member 26 to generate heat during the heat-retaining process of the cooking process. Preferably, the heat generating power of the heat generating member 26 is 20W to 500W.

Preferably, the control device is configured to control the heat generating element 26 to generate heat during a first period (e.g., 30 minutes) during the thermal insulation process. Wherein the duration of the first period includes a first duration (e.g., 20 minutes) and a second duration (e.g., 10 minutes) after the first duration. The control means controls the heat generating element 26 to generate heat for the second period of time and not to generate heat for the first period of time. That is, the heat generating element 26 is operated for 10 minutes (second time period) and stopped for 20 minutes (first time period) in the same operation cycle with 30 minutes (first cycle) as the operation cycle.

Preferably, the second period of time (e.g., 10 minutes) includes at least one second period of time (e.g., 1 minute). The duration of the second period (e.g., 1 minute) includes a third duration (e.g., 20 seconds) and a fourth duration (e.g., 40 seconds) after the third duration. The control device is configured to control the heat generating element 26 to generate heat for a third period of time and not to generate heat for a fourth period of time during the second period of time. That is, the heating element 26 is intermittently heated in the second period, and the intermittent heating cycle is 1 minute (second period), and the operation is stopped for 20 seconds (third period) and 40 seconds (fourth period) within the 1 minute.

Fig. 8 shows a steam valve assembly 140 according to a second embodiment of the present application. In the second embodiment, the steam valve assembly 140 is used to contact the heat generating member 26 of the cover assembly 20, so that condensed water in the steam valve assembly 140 can be heated.

In the second embodiment, the steam valve assembly 140 includes the first steam choked flow condensing chamber 41A, the second steam choked flow condensing chamber 41B, the condensed water accommodating portion WR, the air outlet 51, and the heat conducting portion HC. Vapor valve assembly 140 is configured to allow first vapor-flow-blocking condensing chamber 41A and second vapor-flow-blocking condensing chamber 41B to communicate. Wherein the first steam blocking condensing chamber 41A is for communicating with the cooking space 12 of the cooking appliance 100 to allow steam generated by cooking heating to enter the steam valve assembly 140. The condensed water accommodating portion WR is disposed in the first steam choked flow condensing chamber 41A for storing condensed water (the steam enters the steam valve assembly 140 to dissipate heat and cool down to form condensed water). The air outlet 51 communicates with the second vapor-blocking condensing chamber 41B for releasing vapor. The heat conductive part HC is connected to the condensed water accommodating part WR for conducting heat to heat the condensed water.

As in the first embodiment, the steam valve housing assembly 41 encloses a steam valve cavity 41E. A partition member 160 is provided in the steam valve chamber 41E for partitioning the steam valve chamber 41E into a first steam flow-blocking condensing chamber 41A and a second steam flow-blocking condensing chamber 41B. The partition assembly 160 includes a portion extending at a first angle alpha from the horizontal, wherein alpha is 3 deg. to 90 deg..

In the second embodiment, unlike the first embodiment, first, the partition assembly 160 includes only the first partition 61, and the steam valve chamber 41E is partitioned by the first partition 61 into the first steam flow-blocking condensing chamber 41A and the second steam flow-blocking condensing chamber 41B. Second, the steam valve assembly 140 further includes a pressure relief device 65. The pressure relief device 65 is provided to the first through hole 64 and is movable between an open position and a closed position with respect to the first partition 61, and when the pressure relief device 65 is in the open position, the first vapor block condensation chamber 41A communicates with the second vapor block condensation chamber 41B.

In the second embodiment, the first partitioning member 61 is configured such that at least part of the first vapor block-flow condensing chamber 41A is located below the first through hole 64, and at least part of the second vapor block-flow condensing chamber 41B is located above the first through hole 64. As shown in fig. 8, the pressure relief device 65 includes a gravity ball 69. A gravity ball 69 is mounted to the first through hole 64. The diameter of the gravity ball 69 is larger than the aperture of the first through hole 64. The first partition 61 is configured such that the first through hole 64 is at least lower than a portion of the first partition 61 located at the periphery of the first through hole 64, and at least a portion of the first partition 61 located at the periphery of the first through hole 64 is inclined downward on both sides of the axis P1 of the first through hole 64. Wherein the first partition 61 has a portion extending at a first angle a from the horizontal direction in at least one of both sides of the axis P1 of the first through hole 64.

It will be appreciated that in the second embodiment, the first through hole 64 is located at the locally lowest point of the first partition 61, so that the gravity ball 69 blocks the first through hole 64 by its own weight, so that the first vapor block condensation chamber 41A and the second vapor block condensation chamber 41B cannot communicate. When a large amount of cooking steam enters the first steam flow-blocking condensing cavity 41A, the gravity of the gravity ball 69 is overcome by the high air pressure of the cooking steam, and the gravity ball 69 is propped away from the first through hole 64, so that the first steam flow-blocking condensing cavity 41A and the second steam flow-blocking condensing cavity 41B can be communicated, and the cooking steam enters the second steam flow-blocking condensing cavity 41B and then is discharged out of the steam valve cavity 41E.

After the gravity ball 69 is pushed away from the first through hole 64, it rolls upward along the upper surface of the first partition 61 by the cooking steam (e.g., moves upward and rightward along the upper surface of the portion of the first partition 61 located on the right side of the first through hole 64 in fig. 8). When the force of the cooking steam is reduced, the gravity ball 69 rolls back again to the position of the first through hole 64. Thus, one skilled in the art can experimentally and computationally configure gravity ball 69 such that cooking vapors can overcome the gravity of gravity ball 69, while moisturizing vapors cannot overcome the gravity of gravity ball 69. Thus, the steam valve assembly 140 according to the second embodiment of the present application can normally release cooking steam from the air outlet 51, but hardly release moisture vapor from the air outlet 51, and the moisture vapor is mostly returned from the air inlet pipe outlet 59 into the cooking space 12.

When the gravity ball 69 leaves the first through hole 64, the condensed water in the second vapor block condensation chamber 41B is also allowed to flow back to the first vapor block condensation chamber 41A. In general, condensed water in the second vapor block condensation chamber 41B flows into the first vapor block condensation chamber 41A while the gravity ball 69 returns to the first through hole 64. Preferably, the inclination angles of the portions of the first partition 61 located at the periphery of the first through hole 64 are different on both sides of the axis P1 of the first through hole 64. Preferably, in the portion of the first partition 61 located at the periphery of the first through hole 64 on both sides of the axis P1 of the first through hole 64, the angle with the horizontal direction on the side close to the air outlet 51 is smaller than the angle with the horizontal direction on the side away from the air outlet 51. That is, of the both sides of the axis P1 of the first through hole 64, the side close to the air outlet 51, the first partition 61 is configured to be relatively gentle, and the side far from the air outlet 51, the first partition 61 is configured to be relatively upright. In this way, the gravity ball 69 will roll on a relatively gentle side (because of the relatively small gravitational potential energy that needs to be overcome on this side), and its return to the first through hole 64 will also be relatively prolonged, so that more time is allowed for condensate in the second steam-blocking condensing chamber 41B to flow back into the first steam-blocking condensing chamber 41A.

Preferably, the first partition 61 is configured to extend at the first angle a with respect to the horizontal direction, in both sides of the axis P1 of the first through hole 64, near one side of the air outlet 51.

It can be seen that, in the first embodiment, the entry of the moisturizing vapor into the second vapor-flow-blocking condensing chamber 41B is limited by the "water-sealing" manner, so that the first vapor-flow-blocking condensing chamber 41A and the second vapor-flow-blocking condensing chamber 41B at least include horizontally arranged portions (i.e., the first vapor-flow-blocking condensing chamber 41A and the second vapor-flow-blocking condensing chamber 41B are at least arranged laterally). In the second embodiment, the entry of the moisture vapor into the second vapor-flow-blocking condensing chamber 41B is restricted by the "gravity ball 69", so that the first vapor-flow-blocking condensing chamber 41A and the second vapor-flow-blocking condensing chamber 41B at least include vertically aligned portions (i.e., the first vapor-flow-blocking condensing chamber 41A and the second vapor-flow-blocking condensing chamber 41B are at least vertically aligned).

The remaining non-illustrated portions of the second embodiment refer to the description of the first embodiment.

Fig. 9 shows a steam valve assembly 240 according to a third embodiment of the present application. In the third embodiment, the steam valve assembly 240 is used to contact the heat generating member 26 of the cover assembly 20, so that condensed water in the steam valve assembly 240 can be heated.

In the third embodiment, the steam valve assembly 240 includes the first steam choked flow condensing chamber 41A, the second steam choked flow condensing chamber 41B, the condensed water accommodating portion WR, the air outlet 51, and the heat conducting portion HC. Vapor valve assembly 240 is configured to allow first vapor-flow-blocking condensing chamber 41A and second vapor-flow-blocking condensing chamber 41B to communicate. Wherein the first steam blocking condensing chamber 41A is for communicating with the cooking space 12 of the cooking appliance 100 to allow steam generated by cooking heating to enter the steam valve assembly 240. The condensed water accommodating portion WR is disposed in the first steam choked flow condensing chamber 41A for storing condensed water (the steam enters the steam valve assembly 240 to cool down and dissipate heat to form condensed water). The air outlet 51 communicates with the second vapor-blocking condensing chamber 41B for releasing vapor. The heat conductive part HC is connected to the condensed water accommodating part WR for conducting heat to heat the condensed water.

As in the first and second embodiments, the steam valve housing assembly 41 encloses a steam valve cavity 41E. A partition assembly 260 is provided in the steam valve chamber 41E for partitioning the steam valve chamber 41E into a first steam-flow-blocking condensing chamber 41A and a second steam-flow-blocking condensing chamber 41B. The partition assembly 260 includes a portion extending at a first angle alpha from the horizontal, wherein alpha is 3 deg. to 90 deg..

In the third embodiment, unlike the first embodiment, first, the partition assembly 260 includes only the first partition 61, and the steam valve chamber 41E is partitioned by the first partition 61 into the first steam flow-blocking condensing chamber 41A and the second steam flow-blocking condensing chamber 41B. Second, the steam valve assembly 240 further includes a pressure relief device 65. The pressure relief device 65 is provided to the first through hole 64 and is movable between an open position and a closed position with respect to the first partition 61, and when the pressure relief device 65 is in the open position, the first vapor block condensation chamber 41A communicates with the second vapor block condensation chamber 41B.

Unlike the second embodiment, in the third embodiment, the pressure relief device 65 includes a spring piece 67. The spring 67 is pivotable relative to the first partition 61 between an open position and a closed position. When the elastic sheet 67 is located at the open position, the elastic sheet 67 opens the first through hole 64, so that the first steam flow blocking condensation cavity 41A is communicated with the second steam flow blocking condensation cavity 41B; when the elastic sheet 67 is located at the closed position, the elastic sheet 67 closes the first through hole 64, so that the first vapor choke condensing chamber 41A and the second vapor choke condensing chamber 41B are not communicable. Wherein the biasing force of the spring 67 biases the spring 67 in the closed position, i.e., the biasing force of the spring 67 biases the spring 67 toward the closed position. When the blocking spring 67 is opened, it is opened toward the second vapor-choked flow condensing chamber 41B.

In the third embodiment, after a large amount of cooking steam enters the first steam flow-blocking condensing chamber 41A, the cooking steam overcomes the elastic potential energy of the elastic sheet 67 by virtue of the higher air pressure thereof, and the elastic sheet 67 is pushed open, so that the first steam flow-blocking condensing chamber 41A and the second steam flow-blocking condensing chamber 41B can be communicated, and thus the cooking steam enters the second steam flow-blocking condensing chamber 41B and then is discharged out of the steam valve cavity 41E. When the force of the cooking vapour is reduced, the dome 67 returns to the biased position again. Therefore, the elastic sheet 67 may be constructed by a person skilled in the art through experimental and computational methods such that cooking steam can overcome the elastic potential energy of the elastic sheet 67, while moisturizing steam cannot overcome the elastic potential energy of the elastic sheet 67. Thus, the steam valve assembly 240 according to the third embodiment of the present application can normally release cooking steam from the air outlet 51, but hardly release moisture vapor from the air outlet 51, and the moisture vapor is mostly returned from the air inlet pipe outlet 59 to the cooking space 12.

The first partition 61 is further provided with a second through hole in order to allow condensed water in the second vapor-choked flow condensing chamber 41B to flow back to the first vapor-choked flow condensing chamber 41A. At the second through hole, the first vapor-flow-blocking condensing chamber 41A communicates with the second vapor-flow-blocking condensing chamber 41B, and condensed water in the second vapor-flow-blocking condensing chamber 41B flows back to the first vapor-flow-blocking condensing chamber 41A through the second through hole. Preferably, the first partition 61 extends obliquely in the horizontal direction, and the second through hole is lower than the first through hole 64. That is, the second through holes are provided at a portion (return water portion 61E) of the first partition 61 lower than the first through holes 64 such that the second through holes correspond to portions where condensed water relatively gathers in the second vapor choked flow condensing chamber 41B. Preferably, portions of the first partition 61 higher than the first and second through holes 64 and 61 extend at a first angle a from the horizontal direction.

It will be appreciated that in the third embodiment, the second through hole always maintains the first vapor block condensation chamber 41A in communication with the second vapor block condensation chamber 41B. The person skilled in the art can control the amount of the moisture vapor discharged from the second through hole and the amount of the moisture vapor discharged from the intake pipe outlet 59 by experimental and computational methods, for example, defining the area of the second through hole and the area of the intake pipe outlet 59 so that the moisture vapor tends to be discharged from the intake pipe outlet 59.

Alternatively, the water return portion 61E is provided with a larger second through hole, and a second elastic piece different from the elastic piece 67 is provided at the second through hole. The second spring is pivotable relative to the first partition 61 between a second open position and a second closed position. When the second elastic sheet is positioned at the second opening position, the second elastic sheet opens the second through hole; when the second elastic sheet is positioned at the second closing position, the second elastic sheet closes the second through hole. The biasing force of the second spring plate makes the second spring plate located at the second closing position, namely the biasing force of the second spring plate biases the second spring plate towards the second closing position. When the second elastic piece is opened, it is opened toward the first vapor-choked flow condensing chamber 41A. It can be appreciated that the condensed water is collected on the upper surface of the water return portion 61E. When the condensed water gathers to a certain degree, the condensed water overcomes the elastic potential energy of the second elastic sheet by virtue of the self weight of the condensed water, so that the second elastic sheet is promoted to be opened towards the first steam flow-blocking condensing cavity 41A, and the condensed water can flow back to the first steam flow-blocking condensing cavity 41A. In this embodiment, the moisturizing vapor cannot be released from the second through-holes.
