Referring to fig. 6, the upper deck assembly 10 of the present embodiment is further provided with a steam channel 16, and the steam channel 16 is formed on the mounting case 19. The steam passage 16 serves to discharge steam in the cooking cavity 910 to balance the air pressure in the cooking cavity 910. For convenience of explanation and understanding, one end of the steam channel 16 communicating with the cooking cavity 910 is defined as an inner port 161, and one end of the steam channel 16 communicating with the outside of the mounting case 19 is defined as an outer port 162, according to the positions and roles of both ends of the steam channel 16. In the present embodiment, the inner port 161 is located at one side of the mounting case 19, and when the mounting case 19 covers the cooking cavity 910, the inner port 161 is located at one side of the mounting case 19 facing the cooking cavity 910, so that the inner port 161 communicates with the cooking cavity 910. The outer port 162 is located on the outer surface of the mounting case 19, and the outer port 162 communicates with the inner port 161. In the present embodiment, the steam channel 16 is provided on the mounting case 19 of the upper deck assembly 10, and one end of the steam channel 16 is communicated with the cooking cavity 910 and the other end is communicated with the outside of the upper deck assembly 10.

In addition, in the present embodiment, the outer port 162 of the steam channel 16 is disposed on the outer peripheral sidewall of the mounting shell 19, so as to prevent the steam from being directly sprayed to the user to cause injury.

Referring to fig. 6, in other embodiments, the steam channel 16 may also be provided with a transition cavity 163, the transition cavity 163 being formed in the mounting shell 19. The transition chamber 163 is located at one side of the installation chamber 17, the transition chamber 163 and the installation chamber 17 are juxtaposed in the axial direction of the installation housing 19, and the transition chamber 163 and the installation chamber 17 are disposed independently of each other. The inner port 161 and the outer port 162 are both in communication with the transition chamber 163. The flow path of the steam is easily deduced: steam is formed in the cooking chamber 910, enters the transition chamber 163 through the inner port 161, and is discharged out of the mounting case 19 through the outer port 162 after a little time in the transition chamber 163 linger, i.e., to the outside of the cooking appliance 1000. The provision of the transition chamber 163 can reduce the temperature of the steam, avoid the excessive temperature of the steam discharged from the outer port 162, and the inner surface of the transition chamber 163 can condense a part of the moisture in the steam, avoid excessive water accumulation near the outer port 162 and the cooking appliance 1000.

The size of the inner port 161 and the size of the outer port 162 are not particularly limited in the present application, and there is no necessity for correlation between the size of the inner port 161 and the size of the outer port 162. In some embodiments, the inner port 161 may be sized smaller such that the inner port 161 can not only release air pressure within the cooking cavity 910, but also ensure air pressure within the range of the cooking appliance 1000 within the cooking cavity 910, can accelerate food ripening, and can promote the mouthfeel of food such as rice, porridge, etc. In still other embodiments, the outer port 162 may be sized larger to reduce the flow rate of the discharged steam on the one hand and to promote heat exchange between the inside of the steam channel 16 and the outside of the cooking appliance 1000 on the other hand, and to reduce the temperature of the discharged steam. Further, in the present embodiment, the size of the outer port 162 is larger than the size of the inner port 161.

Referring to fig. 6, the inner port 161 and the fan 41 are both located inside the cooking appliance 1000 and are both engaged with the cooking cavity 910. For ease of illustration and understanding, it is assumed that the axis direction of the shaft 22 is substantially the same as the vertical direction, and the position of the pan body 900 is below with respect to the position of the upper deck assembly 10. The positional relationship between the inner port 161 and the fan 412 and the fan 41 is not particularly limited in the present application, and the inner port 161 may be disposed lower than the fan 412 or higher than the fan 412. In this embodiment, the outer port 162 of the steam channel 16 is communicated with the outside of the upper core assembly 10, the inner port 161 of the steam channel 16 is communicated with the cooking cavity 910, and the distance between the inner port 161 and the opening 810 of the inner container 800 is not smaller than the distance between the pressure generator 40 and the opening 810 of the inner container 800, i.e. the height of the inner port 161 is not lower than the height of the fan blade 412 of the pressure generator 40, which can be understood that the height of the inner port 161 is not lower than the air outlet side 4121 of the fan blade 412. The purpose of this arrangement is to prevent the inner port 161 from being affected by the air flow guided out from the air outlet side 4121, and to prevent steam from entering the steam passage 16 through the inner port 161, so that the steam in the cooking chamber 910 can be effectively discharged, and the air pressure in the cooking chamber 910 can be kept within the bearing range of the cooking device 1000. The side of the fan blade 412 opposite to the air outlet side 4121 (which can be understood as the air inlet side of the fan blade 412) is prevented from being opposite to the inner port 161, so that the fan 41 can be prevented from sucking air outside the cooking utensil 1000 into the cooking cavity through the inner port 161, food in the inner container 800 is prevented from being polluted by dust and bacteria in the air, and food safety is ensured. From the perspective of the relative distance, the distance between the inner port 161 and the opening 810 of the inner container 800 is not smaller than the distance between the pressure generator 40 and the opening 810 of the inner container 800 in the axial direction of the rotation shaft 22.

Referring to fig. 3, the upper deck device 100 of the present embodiment further includes a spacer assembly 60, and the spacer assembly 60 is disposed on a side of the mounting cavity 17 facing away from the upper deck assembly 10, i.e., the mounting shell 19. The baffle assembly 60 is used to cover the mounting cavity 17, and when the mounting housing 19 covers the cooking cavity 910, the baffle assembly 60 separates the mounting cavity 17 from the cooking cavity 910 such that the mounting cavity 17 and the cooking cavity 910 are independent of each other. In this embodiment, the heating assembly 50 is disposed in the mounting cavity 17, and the partition assembly 60 covers the mounting cavity 17, and when the mounting case 19 covers the cooking cavity 910, the pressure generator 40 is disposed on a side of the partition assembly 60 facing away from the mounting cavity 17, and the heating assembly 50 is disposed on a side of the partition assembly 60 facing away from the cooking cavity 910. The setting of this embodiment to heating element 50 and baffle subassembly 60 can avoid the foreign matter in installation cavity 17 and the foreign matter on the installation shell 19 to get into cooking cavity 910 on the one hand, guarantee the food safety of food in the cooking cavity 910, on the other hand can hinder steam and the foam that food cooking liquor formed to get into installation cavity 17, have more molecules in the foam, like starch, protein, still the tiny granule of food, the setting of baffle subassembly 60 can avoid heating element 50 and foam contact, solute and impurity in the foam form the adhesive layer of carbonization at heating element 50's surface, influence heating element 50's heating efficiency. The connection mode between the partition plate assembly 60 and the mounting case 19 is not particularly limited in the present application, and the two may be detachably connected or fixedly connected. The baffle assembly 60 may be formed from a material that is resistant to high temperatures and meets food safety requirements.

Referring to fig. 3, the driving mechanism 20 of the present application may be a rotary driving element, and in this embodiment, the driving mechanism 20 includes a motor 21 and a shaft 22, the motor 21 is disposed on a side of the mounting cavity 17 facing away from the partition board assembly 60, and the motor 21 is not disposed in the mounting cavity 17. The rotating shaft 22 is in transmission connection with the motor 21. The shaft 22 passes through the mounting housing 19, the mounting chamber 17 and the diaphragm assembly 60 in sequence, the shaft 22 extending to a side of the diaphragm assembly 60 facing away from the mounting chamber 17 for connection to the pressure generator 40. In other embodiments, the drive mechanism 20 may also be a swinging drive element, the swinging arms of which extend from the interior of the mounting housing 19 to the side of the diaphragm assembly 60 facing away from the mounting cavity 17.

Referring to fig. 3, the pressure generator 40 of the present embodiment is used to generate positive pressure inside the cooking chamber 910 and inside the inner container 800 to promote foam collapse. Pressure generator 40 is drivingly connected to shaft 22 and is located on a side of diaphragm assembly 60 facing away from mounting chamber 17. When housing 19 is installed to cover cooking cavity 910, pressure generator 40 is positioned in correspondence with cooking cavity 910. The motor 21 is started to drive the rotating shaft 22, and the rotating shaft 22 drives the pressure generator 40 to operate, so that the pressure generator 40 generates positive pressure and leads to the inside of the liner 800.

In some specific application environments, the soup in the liner 800 may generate a lot of foam when heated, and more substances such as starch, protein, soluble sugar, etc. are dissolved in the soup. After the soup forms the foam, the substances are densely distributed on the cambered surface formed by the foam, so that the intermolecular cohesion on the foam is increased and is larger than the tension of the foam, and the foam is not easy to break. The positive pressure generated by the pressure generator 40 can be directed to the inside of the liner 800, the positive pressure acts on the foam, the substances at the arc top of the foam are gathered towards the edge of the arc surface of the foam under the action of the positive pressure, so that the substances at the arc top of the foam are reduced, the tension at the arc top of the foam is increased, the intermolecular cohesive force applied to the arc top of the foam is reduced, and the foam is automatically ruptured and disappears under the action of the tension. In this embodiment, the heating assembly 50 is disposed on the upper core assembly 10, and the heat generated by the heating assembly 50 is directly radiated into the inner container 800 through the opening 810 of the inner container 800, and the heat radiated into the inner container 800 causes the volume of the foam to become larger, so that the intermolecular cohesive force in the foam is further reduced, and the foam is more easily broken.

Referring to fig. 3, the pressure generator 40 in this embodiment includes a fan 41, the fan 41 is located on a side of the partition assembly 60 facing away from the mounting chamber 17, and the fan 41 is in driving connection with the rotating shaft 22. When the cooking cavity 910 is covered by the mounting case 19, the fan 41 is disposed toward the inside of the cooking cavity 910 and the inner container 800, and the fan 41 is rotated and promotes the flow of gas by the driving of the motor 21 to form a positive pressure inside the inner container 800, thereby promoting the rupture of the foam in the inner container 800. In this embodiment, the depth of the liner 800 is defined as h, the diameter of the fan 41 is defined as d, and d and h satisfy the relation: d/h is less than or equal to 2. In other words, h.gtoreq.0.5 d, i.e., the depth h of the inner container 800 is greater than half the diameter d of the fan 41, the purpose of this arrangement is to make the depth of the inner container 800 sufficiently deep relative to the size of the fan 41. On one hand, the distance between the liquid level of the inner container 800 and the upper core assembly 10 can be prolonged, the expansion and spreading space of foam in the inner container 800 can be increased under the condition that the body diameter of the inner container 800 is unchanged, and the foam overflowing probability can be effectively reduced; the larger expansion and spreading space can further prolong the time for the foam to expand and overflow to the upper core assembly 10, so that enough time for eliminating the foam is reserved for the fan 41, the foam is eliminated as early as the foam expands and overflows to the upper core assembly 10, a virtuous circle is formed, and the problem of excessive foam in the pot liner 800 is effectively solved. On the other hand, the inner container 800 is deep enough to have strong heat preservation capability, so that the influence of air flow generated during the operation of the fan 41 on the temperature in the inner container 800 is reduced, and the advantages of the inner container 800 and the cooking utensil 1000 in the self field, namely the food cooking field, are enhanced. The value of d/h is not particularly limited in this embodiment, and the above two beneficial effects can be surrounded, and the configuration is specifically set according to the structure of the actual product. The dimensions of the liner 800 and the fan 41 are not particularly limited in the present application, provided that each part of the structure can be installed and matched with each other. The type of pressure generator 40 in the present application is provided corresponding to drive mechanism 20. The driving mechanism 20 in the present embodiment is a motor 21, and therefore a fan 41 is selected as the pressure generator 40 according to the rotational driving method of the motor 21. If the driving mechanism 20 in other embodiments is a swing type driving element, a structure such as a damper is selected as the pressure generator 40 corresponding to the swing driving mode.

The fan 41 in the embodiment of the present application may be an axial flow fan or a centrifugal fan. Referring to fig. 7, the fan 41 in the present embodiment is an axial fan, which may include a rotating shaft 411 and a plurality of blades 412. The rotation shaft portion 411 is connected to the rotation shaft 22 so that the fan 41 can be driven by the motor 21, and the plurality of blades 412 are arranged at intervals in sequence in the circumferential direction of the rotation shaft portion 411. One side of the fan blade 412 forms an air outlet side 4121, and when the upper core assembly 10 covers the cooking cavity 910, the air outlet side 4121 of the fan blade 412 faces the inside of the inner container 800 to guide air flow into the inside of the inner container 800 and form positive pressure.

The relative positional relationship between the inner container 800 and the fan 41 is not particularly limited in the present application, and the fan blades 412 and the fan 41 may be located above the opening 810 of the inner container 800 or may be located at the opening 810 of the inner container 800. As shown in fig. 8, the present embodiment provides the fan 41 at the opening 810 of the liner 800. Specifically, when the fan 41 is projected onto the plane where the rotation axis is located, the projection profile of the fan blade 412 is partially located outside the projection profile of the inner container 800, and partially located inside the projection profile of the inner container 800, so that the air outlet side 4121 of the fan blade 412 is located inside the inner container 800 and slightly lower than the opening 810. In this embodiment, the fan 41 is configured to include a rotating shaft 411 and a plurality of blades 412, where the blades 412 are sequentially arranged at intervals along the circumferential direction of the rotating shaft 411, and when the upper core assembly 10 covers the cooking cavity 910, the air outlet side 4121 of the blades 412 faces the inside of the inner container 800, and the air outlet side 4121 of the blades 412 is located inside the inner container 800 and slightly lower than the opening 810. The arrangement ensures that the air outlet side 4121 is far enough away from the liquid level of the inner container 800, so that the fan blade 412 can be prevented from adhering to the soup in the inner container 800, and the air flow driven by the fan 41 can be ensured to be mostly led into the inner container 800 to form positive pressure, thereby improving the foam eliminating effect of the fan 41. In other embodiments, as shown in fig. 9, when the fan 412 is projected onto a plane where the rotation axis of the fan 41 is located, the projection profile of the fan 412 is located outside the projection profile of the inner container 800, so that the air outlet side 4121 of the fan 412 is located outside the inner container 800 and slightly higher than the opening 810.

The structure of the fan blade 412 is not particularly limited in the present application, and may be set according to actual requirements. Referring to fig. 7, a fan blade 412 of the present application includes a blade main body 4122 and a wind collecting portion 4123. The wind collecting portion 4123 is connected to the blade main body portion 4122, the wind collecting portion 4123 is located on a side of the blade main body portion 4122 away from the wind outlet side 4121, and the wind collecting portion 4123 protrudes in the rotation direction of the fan 41 with respect to the blade main body portion 4122. The wind collecting portion 4123 can block the airflow from flowing in a direction away from the wind outlet side 4121, so that the airflow carried by the fan 41 is mostly directed to the inside of the liner 800.

For ease of illustration and understanding, it is assumed that the axis direction of the shaft 22 is substantially the same as the vertical direction, and the position of the pan body 900 is below with respect to the position of the upper deck assembly 10. The positional relationship between the inner port 161 and the fan 41 is not particularly limited in the present application, and the inner port 161 may be provided lower than the fan 41 or higher than the fan 41. Referring to fig. 6, in the present embodiment, the height of the inner port 161 is not lower than the height of the fan blade 412, which is to be understood that the height of the inner port 161 is not lower than the height of the air outlet side 4121 of the fan blade 412, so as to avoid that the inner port 161 is affected by the air flow led out from the air outlet side 4121 to prevent steam from entering the steam channel 16 through the inner port 161. From the perspective of the relative distance, the distance between the inner port 161 and the opening 810 of the inner container 800 is not smaller than the distance between the pressure generator 40 and the opening 810 of the inner container 800 in the axial direction of the rotation shaft 22.

Referring to fig. 4, the motor 21 and the shaft 22 are positioned such that the shaft 22 is directed to the cooking cavity 910 when the upper deck assembly 10 covers the cooking cavity 910 according to the present embodiment. In this embodiment, the sealing assembly 30 is sleeved on the rotating shaft 22 and is disposed between the rotating shaft 22 and the upper core assembly 10, so that the upper core assembly 10 is in sealing connection with the rotating shaft 22, which can prevent the oil in the motor 21 from dripping into the cooking cavity 910, prevent the food in the cooking cavity 910 from being polluted, and prevent steam or foam from entering the interior of the upper core assembly 10.

Referring to fig. 10, as can be seen from the above, the rotating shaft 22 in the present embodiment sequentially passes through the mounting shell 19 and the partition plate assembly 60, so that the mounting shell 19 and the partition plate assembly 60 are partially hollowed out to avoid the rotating shaft 22. In order to achieve a sealed connection between the shaft 22 and the mounting housing 19, and between the shaft 22 and the diaphragm assembly 60, the seal assembly 30 in this embodiment includes a first seal 31 and a second seal 32. The first seal 31 is provided between the rotary shaft 22 and the mounting case 19 of the upper deck assembly 10, and the second seal 32 is provided between the rotary shaft 2 and the partition plate assembly 60. The first sealing member 31 and the second sealing member 32 in this embodiment seal the gap generated by the existence of the rotating shaft 22, so as to prevent the gap between the steam rotating shaft 22 and the partition plate assembly 60 and the mounting shell 19 from entering the mounting cavity 17 or the interior of the upper movement assembly 10, and prevent the oil of the motor 21 and the impurities in the interior of the upper movement assembly 10 from entering the cooking cavity, so as to ensure the safety of food in the cooking cavity 910 and also prevent steam or foam from entering the interior of the upper movement assembly 10.

In this embodiment, the mounting shell 19 is provided with a through hole 191, the partition plate assembly 60 is provided with a central through hole 61, and the rotating shaft 22 sequentially penetrates through the through hole 191 and the central through hole 61 and extends to one side of the partition plate assembly 60 away from the mounting cavity 17. The first sealing member 31 is disposed in the avoidance hole 191, and the first sealing member 31 is disposed around the outer periphery of the rotating shaft 22, and the first sealing member 31 is tightly attached to the outer peripheral sidewall of the rotating shaft 22, so as to prevent the oil of the motor 21 from flowing along the rotating shaft 22. And the first sealing member 31 is in rotating fit with the rotating shaft 22, so that the rotating shaft 22 is in rotating fit with the mounting shell 19 while the rotating shaft 22 is in sealing connection with the mounting shell 19, and the rotating shaft 22 can rotate in the avoidance through hole 191 relative to the mounting shell 19.

In the present embodiment, in order to achieve a sealed and rotatable connection of the rotary shaft 22 with the mounting housing 19, the first seal 31 comprises an elastic sealing ring 311. The elastic sealing ring 311 is arranged around and closely attached to the periphery of the rotating shaft 22, the elastic sealing ring 311 is positioned in the avoidance through hole 191, and the periphery of the elastic sealing ring 311 is in sealing connection with the edge structure of the avoidance through hole 191, so that the rotating shaft 22 is in sealing and rotating connection with the mounting shell 19.

In some embodiments, in order to further enhance the sealing effect between the elastic sealing ring 311 and the rotating shaft 22, a plurality of sealing ribs (not shown) are protruding on the inner side wall of the elastic sealing ring 311. The sealing ribs are disposed around and around the periphery of the shaft 22. When the elastic sealing ring 311 is tightly fitted and sleeved on the rotating shaft 22, the sealing ribs are tightly arranged on the rotating shaft 22, so that the tightness between the elastic sealing ring 311 and the rotating shaft 22 can be ensured when the rotating shaft 22 rotates relative to the mounting shell 19 and the elastic sealing ring 311. In other embodiments, the first seal 31 may also be a rotary shaft seal structure such as an oil seal.

Referring to fig. 10, in the present embodiment, the second sealing member 32 is disposed in the central through hole 61, and the second sealing member 32 is disposed around the periphery of the rotating shaft 22, so that the rotating shaft 22 is in sealing connection with the partition assembly 60. In the present application, the second seal 32 may be provided in the same manner as the first seal 31 in the present embodiment, and other seal structures such as an oil seal may be used. Referring to fig. 10, the second sealing member 32 includes a sealing sleeve 321, the sealing sleeve 321 has a through hole 3211, and the through hole 3211 is formed through opposite ends of the sealing sleeve 321 for the spindle 22 to pass through.

In the present embodiment, the outer circumference of the sealing sleeve 321 is in sealing engagement with the edge structure of the central through hole 61, so that foreign matter in the installation cavity 17 can be prevented from entering the cooking cavity 910 through the central through hole 61. The sealing sleeve 321 is spaced from the rotating shaft 22 to prevent the sealing sleeve 321 from limiting the rotating shaft 22 to rotate. In other embodiments, the sealing sleeve 321 may be optionally fitted over the rotating shaft 22. The material of the sealing sleeve 321 is not particularly limited, so that the food safety can be satisfied, and the heat resistance is a selection standard, such as 314 stainless steel, 316 stainless steel, silica gel, and the like.

Pressure generator 40 is capable of generating a positive pressure within cooking chamber 910 upon actuation of drive mechanism 20. The positive pressure can reduce intermolecular polymerization force on the foam and increase tension on the foam, can effectively and rapidly promote automatic breakage and elimination of the foam, can eliminate the need for a steam valve, can simplify the structure of the cooking appliance 1000, and can improve the aesthetic feeling of the appearance of the upper core device 100 and the cooking appliance 1000. The cooking appliance 1000 does not need to frequently adjust heating power. For example, the heating power of the liner heating assembly 700 and/or the heating assembly 50 is maintained at a certain power, excessive foam can be timely eliminated by means of the pressure generator 40, the foam amount in the liner 800 is maintained at a certain degree without frequently adjusting the power of the liner heating assembly 700 and the heating assembly 50, the control logic of the cooking utensil 1000 can be remarkably simplified, and the working stability of the cooking utensil is ensured to be higher. Further, by the defoaming effect of the pressure generator 40, even though the heating power of the liner heating assembly 700 and/or the heating assembly 50 is relatively large, excessive foam generation can be avoided to a certain extent, so that the foam amount can be maintained to a certain extent, and thus the cooking appliance 1000 can be kept to be heated continuously with high heating power, and the cooking time can be shortened. Secondly, for the gap between the rotating shaft 22 of the driving mechanism 20 and the upper core assembly 10, the upper core device 100 in this embodiment is further provided with a sealing assembly 30, and the sealing assembly 30 is disposed between the rotating shaft 22 and the upper core assembly 10, so that the upper core assembly 10 is in sealing connection with the rotating shaft 22, and the interior of the upper core assembly 10 and the interior of the cooking cavity 910 are mutually independent, so that foreign matters in the upper core assembly 10 can be prevented from entering the cooking cavity 910, and steam can be prevented from entering the interior of the upper core assembly 10.
