[0127] Figure 12 is Figure 9 a schematic structural diagram of the steam heater 6 in

[0128] Referring to Figure 9 andFigure 12 As shown, in some embodiments, the steam module may include a steam heater 6.

The steam heater 6 can be disposed outside the inner liner 2. The steam heater 6 can be disposed between the output end of the steam generator 4 and the steam joint 5.

[0129] The output end of the steam generator 4 can be communicated with the input end of the steam heater 6 through a steam pipeline. The output end of the steam heater 6 can be communicated with the steam joint 5 through a steam pipeline. The steam generated by the steam generator 4 can be conveyed into the steam heater 6. The steam heater 6 can perform secondary heating on the steam flowing through the steam heater 6 to increase the steam temperature, and thus generate high-temperature steam. The high-temperature steam heated by the steam heater 6 can be conveyed into the steaming box 3 through the steam joint 5 and the air inlet 3111, which can help increase the steam temperature inside the steaming box 3 and improve the steaming cooking efficiency inside the steaming box 3.

[0130] In some embodiments, a second input pipe 61 may protrude from the outer wall of the steam heater 6. The second input pipe 61 can be the input end of the steam heater 6.

[0133] Please refer to Figure 13 、 Figure 14 and Figure 16 As shown, in some embodiments, a partition 63 may be provided inside the steam heater 6. The partition 63 may divide the interior of the steam heater 6 into a first steam heating chamber 60a and a second steam heating chamber 60b. Vent holes 631 may be formed in the partition 63. The vent holes 631 may communicate the first steam heating chamber 60a and the second steam heating chamber 60b. The input end of the steam heater 6 may communicate with the first steam heating chamber 60a, that is, the second input port 611 may communicate with the first steam heating chamber 60a. The output end of the steam heater 6 may communicate with the second steam heating chamber 60b, that is, the second output port 621 may communicate with the second steam heating chamber 60b.

[0134] When the steam generated by the steam generator 4 is delivered into the steam heater 6, the steam can first enter the first steam heating chamber 60a through the second input port 611 for heating, then enter the second steam heating chamber 60b through the vent holes 631 for reheating, and then be delivered into the interior of the steaming box 3 through the second output port 621, the steam joint 5, and the air inlet 3111. After the steam is heated successively by the first steam heating chamber 60a and the second steam heating chamber 60b, the temperature of the steam can be increased to generate steam at a higher temperature, thereby increasing the temperature of the steam input into the interior of the steaming box 3, which is beneficial to improving the steam cooking efficiency inside the steaming box 3.

[0135] In some embodiments, a heating pipe 64 may be provided inside the steam heater 6. The heating pipe 64 may include a first heating portion 641 and a second heating portion 642.

The second heating portion 642 may extend into and be arranged inside the second steam heating chamber 60b. The second heating portion 642 may be used to heat the second steam heating chamber 60b. When the steam enters the first steam heating chamber 60a, it can be heated by the first heating portion 641. The heated steam can enter the second steam heating chamber 60b through the vent holes 631 and then be heated by the second heating portion 642.

[0136] It should be noted that, in other embodiments, two heating pipes 64 may also be provided inside the steam heater 6. One heating pipe 64 may be arranged inside the first steam heating chamber 60a for separately heating the first steam heating chamber 60a. The other heating pipe 64 may be arranged inside the second steam heating chamber 60b for separately heating the second steam heating chamber 60b.

[0137] Please refer to Figure 13 and Figure 14As shown, in some embodiments, the first heating portion 641 and the second heating portion 642 may be integrally bent and connected. The partition 63 may be provided with a through hole. The first heating portion 641 is bent and connected to the second heating portion 642 through the through hole.

[0138] In some embodiments, the heating pipe 64 may include a first connection section 643 and a second connection section 644. The first connection section 643 and the second connection section 644 may be respectively disposed through the second outer sidewall of the steam heater 6.

[0139] The first connection section 643 may be disposed at one end of the heating pipe 64. The first connection section 643 may serve as one electrode of the heating pipe 64. One end of the first connection section 643 may extend into the first steam heating chamber 60a and be connected to one end of the first heating portion 641.

[0140] The second connection section 644 may be disposed at the other end of the heating pipe 64. The second connection section 644 may serve as the other electrode of the heating pipe 64. One end of the second connection section 644 extends into the second steam heating chamber 60b and is connected to one end of the first heating portion 641. The heating pipe 64 may be externally connected to a power source through the first connection section 643 and the second connection section 644 to supply power to the heating pipe 64, so as to realize the steam heating function in the first steam heating chamber 60a and the second steam heating chamber 60b.

[0141] Please refer to Figure 13 and Figure 14 As shown, in some embodiments, the second input pipe 61 and the second output pipe 62 may be respectively disposed on opposite sides of the partition 63, so that the second input port 611 and the second output port 621 may be respectively disposed on opposite sides of the partition 63. The second input pipe 61 and the second input port 611 therein may be in direct communication with the first heating chamber. The second output pipe 62 and the second output port 621 therein may be in direct communication with the second heating chamber.

[0142] Please refer to Figure 11 and Figure 15 As shown, in some embodiments, the second input pipe 61 and the second output pipe 62 may respectively protrude from the first outer sidewall (not marked in the figure) of the steam heater 6. The second input pipe 61 and the second output pipe 62 may be respectively disposed at opposite ends of the first outer sidewall of the steam heater 6, thereby increasing the path length of the steam in the first steam heating chamber 60a and the second steam heating chamber 60b, and further increasing the contact area between the steam and the heating pipe 64, which is beneficial to increasing the steam temperature output by the steam heater 6.

[0143] Please refer to Figure 13 and Figure 14As shown, in some embodiments, the vent holes 631 on the partition plate 63 can be arranged on the side of the partition plate 63 away from the first outer side wall of the steam heater 6. Therefore, when steam enters the first steam heating chamber 60a through the second inlet 611 and then flows to the vent holes 631, the path length of the steam in the first steam heating chamber 60a can be increased, enabling the steam to fully contact and be heated by the first heating portion 641 of the heating pipe 64, thereby facilitating the increase of the steam temperature in the first steam heating chamber 60a.

[0144] Similarly, when steam enters the second steam heating chamber 60b through the vent holes 631 and then flows to the second outlet 621, the path length of the steam in the second steam heating chamber 60b can be increased, enabling the steam to fully contact and be heated by the second heating portion 642 of the heating pipe 64, which is beneficial to increasing the steam temperature in the second steam heating chamber 60b and thus beneficial to increasing the steam temperature output by the steam heater 6.

[0145] Please refer to Figure 13 and Figure 14 As shown, in some embodiments, the partition plate 63 can be provided with a plurality of vent holes 631. The plurality of vent holes 631 can be arranged at intervals on the side of the partition plate 63 away from the first outer side wall of the steam heater 6. The plurality of vent holes 631 can be arranged at intervals on the side of the partition plate 63 away from the second inlet pipe 61 and the second outlet pipe 62.

[0146] The plurality of vent holes 631 can increase the speed and efficiency of the steam in the first steam heating chamber 60a entering the second steam heating chamber 60b, enabling the steam in different regions of the first steam heating chamber 60a to enter the second steam heating chamber 60b through different vent holes 631, allowing the steam in each region of the first steam heating chamber 60a to flow and be heated by the first heating portion 641 of the heating pipe 64, thereby improving the uniformity of the steam temperature in the first steam heating chamber 60a.

[0147] Similarly, the steam in the first steam heating chamber 60a can enter different regions of the second steam heating chamber 60b through different vent holes 631, enabling the steam in each region of the second steam heating chamber 60b to flow and be heated by the second heating portion 642 of the heating pipe 64, thereby improving the uniformity of the steam temperature in the second steam heating chamber 60b.

[0148] It should be noted that the number of vent holes 631 on the partition plate 63 can be adjusted as needed and is not limited herein.

[0149] Please refer to Figure 11 and Figure 15As shown, in some embodiments, the second input pipe 61 may be disposed at the top region of the first outer wall of the steam heater 6. The second output pipe 62 may be disposed at the bottom region of the first outer wall of the steam heater 6. Since the mass of the steam is relatively light, the steam formed by the steam generator 4 can enter the top region in the first steam heating chamber 60a through the second input pipe 61 first, and then the steam gradually diffuses into the entire first steam heating chamber 60a. After being heated in the first steam heating chamber 60a, it diffuses into the entire second steam heating chamber 60b through the vent hole 631, and then the steam in the second steam heating chamber 60b flows out from the second output pipe 62 at the bottom region. During this steam flow process, the steam can fully flow through the first steam heating chamber 60a and the second steam heating chamber 60b, fully increasing the path length of the steam in the first steam heating chamber 60a and the second steam heating chamber 60b, thereby increasing the contact area between the steam and the heating pipe 64, which is beneficial to increasing the steam temperature output by the steam heater 6.

[0150] Referring to Figure 13 and Figure 16 As shown, in some embodiments, the steam heater 6 may be filled with a void heat-conducting material (not shown in the figure). The void heat-conducting material may be a high-temperature-resistant and high-thermal-conductivity void material, such as a stainless steel wire woven mesh or other porous structure materials. The void heat-conducting material may be filled in the first steam heating chamber 60a. The steam in the first steam heating chamber 60a can flow in the voids of the void heat-conducting material. The first heating portion 641 of the heating pipe 64 may pass through the void heat-conducting material in the first steam heating chamber 60a. The heat generated by the first heating portion 641 can be transferred to the void heat-conducting material. By using the void structure in the void heat-conducting material, the heat exchange area with the steam can be increased, which is beneficial to increasing the steam temperature. At the same time, the thermal radiation of the first heating portion 641 to the outer shell of the steam heater 6 can be reduced, thereby reducing the temperature of the outer shell of the steam heater 6.

[0151] Referring to Figure 14 and Figure 16 As shown, in some embodiments, the void heat-conducting material may be filled in the second steam heating chamber 60b. The steam in the second steam heating chamber 60b can flow in the voids of the void heat-conducting material. The second heating portion 642 of the heating pipe 64 may pass through the void heat-conducting material in the second steam heating chamber 60b. The heat generated by the second heating portion 642 can be transferred to the void heat-conducting material. By using the void structure in the void heat-conducting material, the heat exchange area with the steam can be increased, which is beneficial to increasing the steam temperature. At the same time, the thermal radiation of the second heating portion 642 to the outer shell of the steam heater 6 can be reduced, thereby reducing the temperature of the outer shell of the steam heater 6.

[0180] Refer to ​ and ​ As shown, in some embodiments, a sealing sleeve 71 may be provided at the front port of the exhaust joint 7. The sealing sleeve 71 may be detachably sleeved at the front port of the exhaust joint 7. The sealing sleeve 71 may have an annular structure. The sealing sleeve 71 may be arranged around the peripheral edge of the front port of the exhaust joint 7. A sealing hole 710 may be provided at the center of the sealing sleeve 71. The sealing hole 710 may be arranged on the axis of the exhaust joint 7.

[0181] When the steaming box 3 is placed in the cooking cavity 20, the steam output pipe 313 can pass through the sealing hole 710, and the steam output pipe 313 can pass through the sealing hole 710 and be inserted into the front port of the exhaust joint 7, so that the air outlet 3131 is docked and communicated with the exhaust joint 7. When the steam output pipe 313 passes through the sealing hole 710, the sealing sleeve 71 can be sleeved on the outer periphery of the steam output pipe 313, and thus the gap between the outer wall of the steam output pipe 313 and the inner wall of the exhaust joint 7 can be sealed. By using the sealing sleeve 71 to seal the gap between the outer wall of the steam output pipe 313 and the inner wall of the exhaust joint 7, it can be ensured that the steam can be completely discharged to the outside of the inner container 2 and will not overflow and remain inside the cooking cavity 20.

[0182] In some embodiments, a through hole (not shown in the figure) may be provided on the air guide cover 21. The through hole may be arranged opposite to the front end of the exhaust joint 7. The front end of the exhaust joint 7 may abut against the rear wall of the air guide cover 21, so that the through hole is in direct communication with the front port of the exhaust joint 7.

[0189] ​ is ​Schematic diagram of the structure of the in-place reminder component 17.

[0190] Refer to ​ , ​ and ​ As shown, in some embodiments, the cooking device may include an in-place reminder component 17. The in-place reminder component 17 may include a microswitch 171 and a push rod 172. The microswitch 171 may be disposed outside the inner container 2. The push rod 172 may be movably inserted through the rear side wall of the inner container 2. The microswitch 171 and the push rod 172 may be axially opposed. When the steaming box 3 is pushed into the cooking cavity 20, the steaming box 3 can abut against the push rod 172, causing the push rod 172 to move backward, and causing the push rod 172 to move in the direction of the microswitch 171.

[0191] When the steaming box 3 is pushed into the preset position in the cooking cavity 20, the steam joint 5 is docked and communicated with the air inlet 3111, and the exhaust joint 7 can be directly opposed and communicated with the air outlet 3131. At this time, the push rod 172 can abut against the microswitch 171, so as to trigger an in-place reminder signal by the microswitch 171. According to this in-place reminder signal, reminder methods such as sound and light can be used to remind the user that the steaming box 3 has been pushed in place.

[0192] In some embodiments, the in-place reminder component 17 may include a reset member 173. The reset member 173 can abut against the push rod 172. The reset member 173 can be used to drive the push rod 172 to move toward the inside of the cooking cavity 20. When the steaming box 3 is not placed in the cooking cavity 20 or the steaming box 3 does not contact the push rod 172, the push rod 172 can be separated from the microswitch 171, as ​ shown.

[0193] Refer to ​ , ​ and ​ As shown, in some embodiments, the reset member 173 can be a reset spring. The reset spring can be telescopically sleeved on the push rod 172. When the steaming box 3 pushes the push rod 172 to move in the direction of the microswitch 171, the reset spring is compressed and deformed, as ​ shown. When the steaming box 3 is separated from the push rod 172, the deformation of the reset spring is restored, and the elastic force of the reset spring can drive the push rod 172 to move toward the inside of the cooking cavity 20, and the reset spring elongates, so that the push rod 172 can be separated from the microswitch 171, as ​ shown.

[0194] In some embodiments, abutting ribs 1721 may protrude from the outer peripheral wall of the push rod 172. The return spring may be disposed between the abutting ribs 1721 and the inner wall of the inner container 2. One end of the return spring may abut against the abutting ribs 1721, and the other end of the return spring may abut against the inner wall of the inner container 2. When the steaming box 3 pushes the push rod 172 to move in the direction of the microswitch 171, the distance between the abutting ribs 1721 and the inner wall of the inner container 2 gradually decreases, and the abutting ribs 1721 can compress the return spring.

[0195] In some embodiments, the push rod 172 is movably passed through the rear wall of the inner container 2 and the air guide cover 21 in sequence. When the steaming box 3 is not in contact with the push rod 172, the reset member 173 can drive the front end of the push rod 172 to protrude from the front wall of the air guide cover 21 and extend into the cooking cavity 20. Therefore, when the steaming box 3 is placed in the cooking cavity 20, the steaming box 3 can abut against the front end of the push rod 172, driving the push rod 172 to move backward and abut against the microswitch 171.

[0196] Refer to ​ As shown, in some embodiments, a perforation (not labeled in the figure) may be provided on the rear wall of the inner container 2, and a seal 26 may be provided at the perforation. The seal 26 may be annular. The push rod 172 may be slidably passed through the seal 26, so that the seal 26 can be sealingly sleeved on the outer periphery of the push rod 172. The seal 26 can be used to seal the gap between the outer peripheral wall of the push rod 172 and the peripheral side edge of the perforation.

[0197] Refer to ​ and ​ As shown, in some embodiments, the microswitch 171 may be spaced apart and disposed on the back side of the rear wall of the inner container 2, so that there is a certain interval between the microswitch 171 and the rear wall of the inner container 2. When the steaming box 3 is not in contact with the push rod 172, the rear end of the push rod 172 may protrude from the rear wall of the inner container 2. When the steaming box 3 is placed in the cooking cavity 20, the steaming box 3 can push the push rod 172 to move backward, so that the rear end of the push rod 172 can move backward and abut against the microswitch 171.

[0198] In some embodiments, the microswitch 171 may be disposed on the back side of the support back plate 14. A fixing frame 174 may be provided on the back side of the support back plate 14. The microswitch 171 may be detachably fixed on the fixing frame 174.

[0199] Refer to ​ As shown, in some embodiments, abutting plates 3141 may protrude from the outer peripheral wall of the rear end of the pushing tube 314. The rear end of the steam output tube 313 may protrude and extend backward from the abutting plates 3141. The abutting plates 3141 may be annular, and the abutting plates 3141 may be circumferentially arranged around the outer peripheral wall of the pushing tube 314.

[0200] When the steam box 3 is placed in the cooking cavity 20, the push plate 3141 can abut against the push rod 172, which can drive the push rod 172 to move backward, thereby causing the push rod 172 to abut against the micro switch 171. When the push rod 172 abuts against the micro switch 171, the steam output pipe 313 can be inserted into the exhaust connector 7, and the air outlet 3131 can be connected to the exhaust connector 7.

[0201] It should be noted that, in other embodiments, the arrival reminder component 17 may also be provided on other side walls of the inner container 2 .

[0202] See ​ and ​ As shown, in some embodiments, the cooking device may include a temperature sensor 74. The temperature sensor 74 may be located at the rear end of the exhaust connector 7. The temperature sensor 74 may be located outside the inner pot 2. When the steam generator 4 introduces steam into the steam box 3, excess steam inside the steam box 3 can be discharged through the air outlet 3131 and the exhaust connector 7. At this time, the temperature sensor 74 can detect the gas temperature inside the exhaust connector 7 and thereby obtain the steam temperature inside the steam box 3, thereby facilitating detection of the cooking temperature inside the steam box 3. This solution eliminates the need for the temperature sensor 74 to be placed inside the steam box 3 or to be in direct contact with the steam box 3. Instead, the temperature sensor 74 can be directly mounted outside the inner pot 2, facilitating installation and detection of the temperature sensor 74.

[0203] See ​ and ​ As shown, in some embodiments, the cooking device may include an exhaust pipe. The exhaust pipe may be disposed outside the inner pot 2. The lower end of the exhaust pipe may be connected to a transfer pipe 75. The exhaust pipe may be connected to the outer end of the exhaust connector 7 via the transfer pipe 75. The gas or steam in the steam box 3 may be discharged from the inner pot 2 through the gas outlet 3131, the exhaust connector 7, the transfer pipe 75, and the exhaust pipe.

[0204] See ​ and ​ As shown, in some embodiments, the rear end of the exhaust connector 7 may be provided with a transfer tube 75. The transfer tube 75 may be provided outside the inner liner 2. One end of the transfer tube 75 may be connected to the rear end of the exhaust connector 7. The other end of the transfer tube 75 may be used to connect to the exhaust pipe, so that the gas inside the steam box 3 can be discharged in sequence through the air outlet 3131, the exhaust connector 7, the transfer tube 75 and the exhaust pipe. The temperature sensor 74 may be provided on the transfer tube 75. The temperature sensor 74 may be arranged opposite to the rear port of the exhaust connector 7. Therefore, the temperature sensor 74 may be arranged outside the inner liner 2 along with the transfer tube 75. After the exhaust connector 7 is passed through the rear wall of the inner liner 2, the exhaust connector 7 is connected to the transfer tube 75 to facilitate the installation and removal of the temperature sensor 74.

[0205] It should be noted that in some other embodiments, the lower end of the exhaust pipe may also be directly communicated with the outer end of the exhaust joint 7.

[0206] Refer to ​ and ​ As shown, in some embodiments, a detection tube 751 may be convexly provided on the outer wall of the adapter tube 75. The inside of the detection tube 751 may be communicated with the inside of the adapter tube 75. The detection tube 751 may be arranged opposite to the rear port of the exhaust joint 7. The temperature sensor 74 may be arranged inside the detection tube 751. The detection tube 751 may be provided for the alignment installation of the temperature sensor 74 to ensure that the temperature sensor 74 can be directly arranged opposite to the rear end of the exhaust joint 7, facilitating the installation and disassembly of the temperature sensor 74. Therefore, when the excess steam inside the steaming box 3 can be discharged through the air outlet 3131 and the exhaust joint 7, it can enter the inside of the detection tube 751 from the rear port of the exhaust joint 7, facilitating the temperature sensor 74 to perform temperature detection.

[0207] In some embodiments, the length of the temperature sensor 74 may also be greater than that of the detection tube 751. One end of the temperature sensor 74 may extend out of the detection tube 751 and extend into the inside of the adapter tube 75 and the exhaust joint 7, so as to more accurately detect the steam temperature inside the exhaust joint 7, and further more accurately obtain the steam temperature and cooking temperature inside the steaming box 3.

[0208] In some embodiments, an end cap 752 may be sleeved on the outer end of the detection tube 751. The end cap 752 may cover the outer port of the detection tube 751. The end cap 752 may encapsulate the temperature sensor 74 inside the detection tube 751. A wire passing hole (not marked in the figure) may be provided on the end cap 752. The connecting wire of the temperature sensor 74 may pass through the wire passing hole. The end cap 752 may seal the outer port of the detection tube 751, fix the temperature sensor 74 in the detection tube 751, and prevent steam from overflowing from the detection tube 751.

[0209] Refer to ​ 、 ​ and ​ As shown, in some embodiments, one end of the adapter tube 75 away from the exhaust joint 7 may be bent upward and extended. The detection tube 751 may be convexly provided on the outer wall at the bent portion of the adapter tube 75. By using the upward bending structure design of the adapter tube 75, it is convenient to arrange the exhaust pipe above the adapter tube 75, facilitating the upward discharge of steam into the exhaust pipe.

[0210] In some embodiments, the interior of the detection tube 751 may be axially aligned with the rear port of the exhaust joint 7. When the exhaust joint 7 is axially docked and connected to the air outlet 3131 in the steam output pipe 313, the detection tube 751 may be disposed directly behind the steam output pipe 313, such that the detection tube 751 and the air outlet 3131 of the steaming box 3 are axially opposed. Therefore, when the steam in the steaming box 3 is discharged from the exhaust port, it can directly flow backward into the interior of the detection tube 751, thereby improving the accuracy of the temperature detection by the temperature sensor 74.

[0211] Refer to ​ and ​ As shown, in some embodiments, the cooking device may include a condenser 8. The condenser 8 may be disposed on the exhaust pipe. The condenser 8 may be located above the exhaust joint 7. The condenser 8 may be located above the adapter pipe 75. The condenser 8 can condense the gas flowing through the exhaust pipe, improving the condensation performance of the exhaust gas. The condensed water can flow downward along the exhaust pipe and flow back into the interior of the steaming box 3 through the adapter pipe 75, the exhaust joint 7, and the air outlet 3131. The water flowing back into the interior of the steaming box 3 can be stored in the bottom area of the steaming box 3 and can be turned back into steam under the action of the high temperature inside the steaming box 3, thereby improving the utilization rate of the condensed water.

[0212] In some embodiments, one end of the exhaust pipe away from the exhaust joint 7 may extend into and be disposed in the heat dissipation air duct. Therefore, the gas condensed by the condenser 8 can be discharged into the heat dissipation air duct through the exhaust pipe, enhancing the condensation performance of the steam or gas discharged from the steaming box 3.

The steaming grid 33 may adopt a plate-like structure. The steaming grid 33 may have a mesh structure. The top surface of the steaming grid 33 may be used to place the ingredients to be steamed. The steaming grid 33 can divide the interior space of the steaming box 3 vertically into an upper steaming cavity 30a and a lower steaming cavity 30b. The upper steaming cavity 30a may be formed above the steaming grid 33. The lower steaming cavity 30b may be formed below the steaming grid 33.

[0215] When steam enters the steaming box 3 through the steam inlet 3111, the steam can enter the upper steaming cavity 30a and the lower steaming cavity 30b. The steam in the upper steaming cavity 30a and the lower steaming cavity 30b can flow through the mesh holes of the steaming net 33 to increase the contact area between the steam and the food ingredients on the steaming net 33, thereby improving the steam cooking efficiency inside the steaming box 3.

[0216] It should be noted that in some other embodiments, the food ingredients can also be placed inside the lower steaming cavity 30b for steaming.

[0217] In some embodiments, the steam inlet 3111 can be located below the steaming net 33. The steam inlet 3111 can be communicated with the lower steaming cavity 30b. When the steaming box 3 is pushed into the cooking cavity 20, the steam inlet 3111 can be docked and communicated with the steam joint 5, and the steam generator 4 can introduce steam into the lower steaming cavity 30b through the steam joint 5 and the steam inlet 3111, and then flow through the mesh holes on the steaming net 33 to the inside of the upper steaming cavity 30a, thereby steaming the food ingredients on the steaming net 33.

[0218] In some embodiments, the air outlet 3131 can be located above the steaming net 33. The air outlet 3131 can be communicated with the upper steaming cavity 30a. When the steaming box 3 is pushed into the cooking cavity 20, the air outlet 3131 can be docked and communicated with the exhaust joint 7, and the air and steam in the upper steaming cavity 30a can be discharged from the steaming box 3 and the inner liner 2 through the air outlet 3131 and the exhaust joint 7. By allowing the steam to enter from the lower steaming cavity 30b and exit from the upper steaming cavity 30a, it can ensure that the steam passes through the steaming net 33, thereby ensuring that the steam can steam the food ingredients on the steaming net 33 and improving the steam cooking efficiency inside the steaming box 3.

[0219] In some embodiments, the steaming net 33 can be detachably mounted inside the steaming box 3. In other embodiments, the steaming net 33 can also be integrally formed and mounted inside the steaming box 3.

[0220] Refer to ​ and ​ As shown, in some embodiments, support ribs 315 can be convexly provided on the inner sidewall of the steaming box 3. The peripheral edge of the steaming net 33 can be detachably supported on the support ribs 315. The support ribs 315 can be arranged to extend in the vertical direction. The support ribs 315 can extend upward from the inner bottom surface of the steaming box 3. The peripheral edge of the steaming net 33 can be supported by the support ribs 315, thereby mounting the steaming net 33 inside the steaming box 3 and maintaining a certain preset distance between the steaming net 33 and the inner bottom surface of the steaming box 3. [[ID=,20]]

[0221] In some embodiments, on the inner sidewall of the steaming box 3, a plurality of supporting ribs 315 may be provided. The plurality of supporting ribs 315 are circumferentially spaced and arranged on the inner peripheral wall of the steaming box 3. The circumferential side edge of the steaming net 33 can be detachably supported on the plurality of supporting ribs 315. By supporting different positions of the circumferential side edge of the steaming net 33 with the plurality of supporting ribs 315, the stability of the steaming net 33 can be improved, and the steaming net 33 can be prevented from toppling inside the steaming box 3.

[0222] It should be noted that the number of the supporting ribs 315 and the spacing width between the supporting ribs 315 can be adjusted as needed and are not limited herein.

[0223] In some embodiments, the plurality of supporting ribs 315 on the inner wall of the steaming box 3 can be divided into two groups. One group of supporting ribs 315 can be provided on the front sidewall inside the steaming box 3. The other group of supporting ribs 315 can be provided on the rear sidewall inside the steaming box 3. The two groups of supporting ribs 315 can support the front and rear side edges of the steaming net 33.

[0224] It should be noted that in other embodiments, among the two groups of supporting ribs 315, one group of supporting ribs 315 can be provided on the left sidewall inside the steaming box 3. The other group of supporting ribs 315 can be provided on the right sidewall inside the steaming box 3.
