Therefore, when the steaming box 3 is pushed backward into the cooking cavity 20, the steam joint 5 can smoothly enter the interface 3121, and then be inserted into the air inlet 3111 along the interface 3121, so that the steam joint 5 and the air inlet 3111 can be smoothly docked and communicated, improving the convenience of use for users.

[0151] In some embodiments, the mating interface 3121 may adopt a tapered hole structure. The front port of the mating interface 3121 may communicate with the rear port of the air inlet 3111. The diameter of the rear port of the mating interface 3121 may be larger than that of the front port of the mating interface 3121, so that the peripheral side wall of the mating interface 3121 presents a tapered structure. With the tapered mating interface 3121, the steam joint 5 can enter from any tapered wall of the mating interface 3121, allowing a certain docking error between the air inlet 3111 and the steam joint 5, so that the steam joint 5 and the air inlet 3111 can be more smoothly docked and communicated.

[0152] It should be noted that in other embodiments, the steam input pipe 311 may also be provided on other outer walls of the steaming box 3. At this time, one end of the air inlet 3111 may communicate with the inside of the steaming box 3, and the other end of the air inlet 3111 may communicate with the mating interface 3121. The mating interface 3121 may be provided at one end of the air inlet 3111 away from the inside of the steaming box 3.

[0153] Refer to Figure 14 As shown, in some embodiments, the diameter of the front port of the mating interface 3121 may be smaller than that of the rear port of the air inlet 3111, so that the steam joint 5 can be smoothly inserted into the air inlet 3111 along the rear port of the mating interface 3121. It should be noted that in other embodiments, the diameter of the front port of the mating interface 3121 may also be equal to that of the rear port of the air inlet 3111.

[0154] Refer to Figure 14 and Figure 18 As shown, in some embodiments, the docking pipe 312 may be detachably sleeved on the outer periphery of the steam input pipe 311. External threads (not shown in the figure) may be provided on the outer peripheral wall of the steam input pipe 311. Internal threads (not shown in the figure) may be provided inside the front end of the docking pipe 312. The docking pipe 312 may be threadedly sleeved on the outer periphery of the steam input pipe 311. When the docking pipe 312 is threadedly sleeved on the outside of the steam input pipe 311, the air inlet 3111 and the mating interface 3121 may be coaxially docked and communicated.

[0155] It should be noted that in some other embodiments, the docking pipe 312 may also be integrally formed with the steam input pipe 311.

A first mounting opening 3101 can be provided on the rear wall of the steaming box 3. The steam input pipe 311 can be detachably passed through the first mounting opening 3101. The steam input pipe 311 can be quickly disassembled and assembled through the first mounting opening 3101, so as to simplify the structure of the steaming box 3.

[0158] It should be noted that, in some other embodiments, the steam input pipe 311 can also be detachably disposed on other side walls of the steaming box 3. In some other embodiments, the steam input pipe 311 can also be integrally formed on the rear wall or other side walls of the steaming box 3.

[0159] Refer to Figure 18 and Figure 19 As shown, in some embodiments, a first fixing plate 3112 can be convexly provided on the outer peripheral wall of the inner end of the steam input pipe 311. The first fixing plate 3112 can be disposed on the inner side wall of the steaming box 3. The external thread on the outer peripheral wall of the steam input pipe 311 can be disposed outside the steaming box 3. When the docking pipe 312 is sleeved on the outside of the steam input pipe 311, the first fixing plate 3112 and the end of the docking pipe 312 can be clamped on the inner and outer sides of the side wall of the steaming box 3, and thus the steam input pipe 311 can be fixed on the side wall of the steaming box 3.

[0161] Refer to Figures 21 to 23 As shown, in some embodiments, a steam output pipe 313 is provided on the rear wall of the steaming box 3, and an air outlet 3131 can be provided inside the steam output pipe 313. The air outlet 3131 can communicate with the inside of the steaming box 3. The air or steam inside the steaming box 3 can be discharged outside the steaming box 3 through the air outlet 3131 inside the steam output pipe 313.

[0162] It should be noted that, in some other embodiments, the steam output pipe 313 can also be disposed on other outer walls of the steaming box 3.

[0163] Refer to Figure 21As shown, in some embodiments, the cooking device may include an exhaust joint 7. The exhaust joint 7 may penetrate through the rear wall of the inner container 2. The front end of the exhaust joint 7 may be arranged in the blower compartment 210. The rear end of the exhaust joint 7 may protrude out of the rear wall of the inner container 2. When the steaming box 3 is placed inside the cooking cavity 20, the steam output pipe 313 can be arranged opposite to the exhaust joint 7, and the steam output pipe 313 can be docked and communicated with the exhaust joint 7, so that the air in the steaming box 3 can be discharged out of the inner container 2 in sequence through the air outlet 3131 and the exhaust joint 7.

[0164] In some embodiments, when the steaming box 3 is placed inside the cooking cavity 20, the steam output pipe 313 can be inserted into the exhaust joint 7, so that the air outlet 3131 is docked and communicated with the exhaust joint 7.

[0165] It should be noted that, in some other embodiments, when the steaming box 3 is placed inside the cooking cavity 20, the exhaust joint 7 can also be inserted into the steam output pipe 313, so that the air outlet 3131 is docked and communicated with the exhaust joint 7.

[0166] Figure 24 is Figure 23 a partial decomposition schematic diagram of.

[0167] Refer to Figure 23 and Figure 24 As shown, in some embodiments, the steam output pipe 313 can be detachably arranged on the rear wall of the steaming box 3. A second installation opening 3102 can be provided on the rear wall of the steaming box 3. The steam output pipe 313 can be detachably penetrated through the second installation opening 3102. The steam output pipe 313 can be quickly disassembled and assembled through the second installation opening 3102, so as to simplify the structure of the steaming box 3.

[0168] It should be noted that, in some other embodiments, the steam output pipe 313 can also be detachably arranged on other side walls of the steaming box 3. In some other embodiments, the steam output pipe 313 can also be integrally formed on the rear wall or other side walls of the steaming box 3.

[0169] In some embodiments, a second fixing plate 3132 can be protrudingly provided on the outer peripheral wall of the inner end of the steam output pipe 313. The second fixing plate 3132 can be arranged on the inner side wall of the steaming box 3. A pushing pipe 314 is sleeved outside the steam output pipe 313. The pushing pipe 314 can be detachably sleeved on the outer periphery of the steam output pipe 313.

[0170] When the pushing pipe 314 is sleeved outside the steam output pipe 313, the second fixing plate 3132 and the end of the pushing pipe 314 can be clamped on the inner and outer sides of the side wall of the steaming box 3, and further the steam output pipe 313 can be fixed on the side wall of the steaming box 3.

[0171] Refer to Figures 21 to 24As shown, in some embodiments, an external thread (not labeled in the figure) may be provided on the outer peripheral wall of the steam output pipe 313. An internal thread (not labeled in the figure) may be provided inside the front end of the pushing pipe 314. The pushing pipe 314 may be threadedly sleeved on the outer periphery of the steam output pipe 313. When the pushing pipe 314 is threadedly sleeved on the outer periphery of the steam output pipe 313, the second fixing plate 3132 and the end of the pushing pipe 314 may clamp on the inner and outer sides of the side wall of the steaming box 3, and thus the steam output pipe 313 can be fixed on the side wall of the steaming box 3.

[0172] It should be noted that, in some other embodiments, the pushing pipe 314 may also be integrally formed with the steam output pipe 313.

[0173] Figure 25 is Figure 21 A structural schematic diagram in another state.

[0174] Refer to Figure 21 and Figure 25 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 at the axis of the exhaust joint 7.

[0175] 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 in butt - joint communication 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. 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 can ensure that the steam can be completely discharged to the outside of the inner tank 2 and will not overflow into the cooking cavity 20.

[0176] In some embodiments, a through - hole (not labeled in the figure) may be provided on the air guide cover 21. The through - hole may be arranged directly 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 - facing communication with the front port of the exhaust joint 7. When the steaming box 3 is placed in the cooking cavity 20, the steam output pipe 313 can pass through the through - hole and be inserted into the front port of the exhaust joint 7.

[0177] Refer to Figure 21 and Figure 25As shown, in some embodiments, the front end face of the sealing sleeve 71 can abut against the rear wall of the air guide cover 21. The sealing sleeve 71 can be arranged opposite to the through hole. The through hole can be directly communicated with the sealing hole 710. The sealing sleeve 71 can seal the gap between the through hole and the front end face of the exhaust joint 7.

[0178] In some embodiments, positioning ribs 711 can be convexly provided on the front end face of the sealing sleeve 71. The positioning ribs 711 can be annular. The positioning ribs 711 can be arranged along the peripheral side edge of the through hole. The positioning ribs 711 can be inserted into the through hole. Since the contour shape of the positioning ribs 711 matches the through hole, the positioning ribs 711 can position the sealing sleeve 71 at the through hole. When the steaming box 3 is placed in the cooking cavity 20, the steam output pipe 313 can pass through the positioning ribs 711 and then pass through the through hole and be inserted into the sealing hole 710.

[0179] Refer to Figure 21 and Figure 25 As shown, in some embodiments, fixing ribs 72 are convexly provided on the outer peripheral wall of the exhaust joint 7. The fixing ribs 72 can be arranged in the blower housing 210. The fixing ribs 72 can abut against the rear wall inside the inner container 2. By abutting the fixing ribs 72 against the rear wall inside the inner container 2, when the exhaust joint 7 is docked with the steam output pipe 313, axial limitation can be performed on the rear end of the exhaust joint 7 to prevent the exhaust joint 7 from moving backward, ensuring that the exhaust joint 7 can be stably docked and communicated with the air outlet 3131 of the steaming box 3.

[0180] In some embodiments, a second fixing sleeve 73 can be sleeved on the outer periphery of the rear end of the exhaust joint 7. The second fixing sleeve 73 can be arranged outside the inner container 2. The second fixing sleeve 73 can abut against the rear wall of the inner container 2. The fixing ribs 72 and the second fixing sleeve 73 can clamp the front and rear sides of the rear wall of the inner container 2, and thus the exhaust joint 7 can be axially fixed on the rear wall of the inner container 2 to achieve axial fixation of the exhaust joint 7. When the front end of the exhaust joint 7 is separated from the air outlet 3131 of the steaming box 3, the second fixing sleeve 73 can abut against the rear wall of the inner container 2 to prevent the exhaust joint 7 from moving forward, ensuring that the exhaust joint 7 and the steaming box 3 can be smoothly separated from each other.

[0181] In some embodiments, an external thread (not shown in the figure) is provided on the outer peripheral wall of the rear end of the exhaust joint 7. A corresponding internal thread (not shown in the figure) can be provided inside the second fixing sleeve 73. The second fixing sleeve 73 can be threadedly sleeved on the outer peripheral wall of the rear end of the exhaust joint 7.

[0182] It should be noted that in other embodiments, the second fixing sleeve 73 can also be fixed on the outer peripheral wall of the rear end of the exhaust joint 7 by means of clamping or interference fit.

[0183] Figure 26 is Figure 25Schematic diagram of the structure of the in-place reminder component 17.

[0184] Refer to Figure 21 , Figure 25 and Figure 26 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 micro switch 171 and a push rod 172. The micro switch 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 micro switch 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 move in the direction of the micro switch 171.

[0185] 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 opposite and communicated with the air outlet 3131. At this time, the push rod 172 can abut against the micro switch 171 to trigger an in-place reminder signal. 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.

[0186] In some embodiments, the in-place reminder component 17 may include a reset member 173. The reset member 173 may abut against the push rod 172. The reset member 173 may 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 micro switch 171, as Figure 25 shown.

[0187] Refer to Figure 21 , Figure 25 and Figure 26 As shown, in some embodiments, the reset member 173 may be a reset spring. The reset spring may 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 micro switch 171, the reset spring is compressed and deformed, as Figure 21 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. The reset spring elongates, causing the push rod 172 to be separated from the micro switch 171, as Figure 25 shown.

[0188] 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 space 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.

[0189] 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.

[0190] Refer to Figure 25 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 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.

[0191] Refer to Figure 25 and Figure 26 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. 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.

[0192] 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 to the fixing frame 174.

[0193] Refer to Figures 21 to 25 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.

[0194] When the steam box 3 is placed in the cooking cavity 20, the push plate 3141 can abut against the push rod 172, and the push plate 3141 can drive the push rod 172 to move backward, so that the push rod 172 can 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 joint 7, and the exhaust port 3131 can be connected to the exhaust joint 7.

[0195] It should be noted that, in other embodiments, the arrival reminder component 17 may also be disposed on other side walls of the inner container 2 .

[0196] See also Figure 21 and Figure 25 As shown, in some embodiments, the cooking device may include a temperature sensor 74. The temperature sensor 74 may be disposed at the rear end of the exhaust joint 7. The temperature sensor 74 may be disposed outside the inner pot 2. When the steam generator 4 introduces steam into the steam box 3, the excess steam inside the steam box 3 can be discharged through the gas outlet 3131 and the exhaust joint 7. At this time, the temperature sensor 74 can detect the gas temperature in the exhaust joint 7, thereby obtaining the steam temperature inside the steam box 3, thereby facilitating the detection of the cooking temperature inside the steam box 3. This solution can make it possible for the temperature sensor 74 to be placed in the steam box 3 without being in direct contact with the steam box 3, so that the temperature sensor 74 can be directly installed outside the inner pot 2, which can facilitate the installation and detection of the temperature sensor 74.

[0197] See also Figure 4 and Figure 11 As shown, in some embodiments, the cooking device may include an exhaust pipe (not shown). The exhaust pipe may be arranged outside the inner pot 2. The lower end of the exhaust pipe may be connected to the outer end of the exhaust joint 7. The gas or steam in the steam box 3 may be discharged from the inner pot 2 through the gas outlet 3131, the exhaust joint 7, and the exhaust pipe in sequence.

[0198] See also Figure 21 and Figure 25 As shown, in some embodiments, a transfer tube 75 may be provided at the rear end of the exhaust connector 7. 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 communicate with the exhaust pipe, so that the gas inside the steam box 3 can be discharged through the gas outlet 3131, the exhaust connector 7, the transfer tube 75 and the exhaust pipe in sequence. 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.

[0199] 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.

[0200] Refer to Figure 21 and Figure 25 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 provided inside the detection tube 751. The detection tube 751 may be used for the alignment and 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, which is convenient for 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, so as to facilitate the temperature sensor 74 to perform temperature detection.

[0201] 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 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.

[0202] 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.

[0203] Refer to Figure 4 、 Figure 11 and Figure 25 As shown, in some embodiments, one end of the adapter tube 75 away from the exhaust joint 7 may be bent and extended upward. The detection tube 751 may be convexly provided on the outer wall at the bending part 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, which is convenient for the steam to be discharged upward into the exhaust pipe.

[0204] In some embodiments, the interior of the detection tube 751 can be axially aligned and communicated with the rear port of the exhaust joint 7. When the exhaust joint 7 is axially docked and communicated with the air outlet 3131 in the steam output pipe 313, the detection tube 751 can be disposed opposite to the rear side of the steam output pipe 313, so that the detection tube 751 and the air outlet 3131 of the steaming box 3 can be axially oppositely arranged. 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 of the temperature sensor 74.

[0205] Refer to Figure 4 and Figure 11 As shown, in some embodiments, the cooking device may include a condenser 8. The condenser 8 can be provided on the exhaust pipe. The condenser 8 can be located above the exhaust joint 7. The condenser 8 can 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 re-converted into steam under the high temperature inside the steaming box 3, thereby improving the utilization rate of the condensed water.

[0206] In some embodiments, a condensation chamber (not shown in the figure) can be formed inside the condenser 8. The steam flowing through the condenser 8 can be condensed through the condensation chamber, and the condensed water can flow back into the exhaust pipe along the wall of the condensation chamber and can flow downward along the exhaust pipe, and finally flow back into the interior of the steaming box 3.

[0207] In some embodiments, the exterior of the condenser 8 may have a first interface 81 and a second interface 82 communicating with the condensation chamber. The first interface 81 can be provided at the bottom of the condensation chamber. The first interface 81 can serve as the inlet of the condensation chamber. The second interface 82 can be provided at the top of the condensation chamber. The second interface 82 can serve as the outlet of the condensation chamber. The gas or steam flowing through the exhaust pipe can enter the condensation chamber through the first interface 81 for condensation, and the condensed gas can be discharged through the second interface 82. The condensed water can flow back into the exhaust pipe through the first interface 81.

[0208] In some embodiments, the exhaust pipe may include a first exhaust section (not shown in the figure) and a second exhaust section (not shown in the figure). The bottom end of the first exhaust section may be connected to the exhaust joint 7 through a swivel joint 75. The top end of the first exhaust section may be connected to the first interface 81. One end of the second exhaust section may be connected to the second interface 82. Therefore, the gas in the steaming box 3 can enter the condensation chamber through the air outlet 3131, the exhaust joint 7, the first exhaust section and the first interface 81 for condensation. The condensed gas can be discharged through the second interface 82 and the second exhaust section. The condensed water formed in the condensation chamber can flow downward along the first exhaust section and flow back into the interior of the steaming box 3 through the exhaust joint 7 and the air outlet 3131.

[0209] In some embodiments, one end of the exhaust pipe away from the exhaust joint 7 may extend into and be arranged in the heat dissipation air duct. One end of the second exhaust section away from the second interface 82 may extend into and be arranged in the heat dissipation air duct. Therefore, the gas condensed by the condensation chamber of the condenser 8 can be discharged into the heat dissipation air duct through the second exhaust section, improving the condensation performance of the steam or gas discharged from the steaming box 3.

[0210] Refer to Figure 11 As shown, in some embodiments, the condenser 8 may have a water inlet joint 83 and a water outlet joint 84.

[0213] Refer to Figure 27 and Figure 28As shown, in some embodiments, the steaming box 3 may include a steaming net 33. The steaming net 33 may be erected inside the steaming box 3. The steaming net 33 may adopt a plate-like structure. The steaming net 33 may have a mesh structure. The top surface of the steaming net 33 may be used to place the ingredients to be steamed. The steaming net 33 may divide the internal 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 net 33. The lower steaming cavity 30b may be formed below the steaming net 33.

[0214] When steam enters the interior of the steaming box 3 through the air inlet 3111, the steam may 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 may flow through the mesh holes of the steaming net 33 to increase the contact area between the steam and the ingredients on the steaming net 33, thereby improving the steam cooking efficiency inside the steaming box 3.

[0215] It should be noted that, in some other embodiments, the ingredients may also be placed inside the lower steaming cavity 30b for steaming.

[0216] In some embodiments, the air inlet 3111 may be located below the steaming net 33. The air inlet 3111 may communicate with the lower steaming cavity 30b. When the steaming box 3 is pushed into the cooking cavity 20, the air 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 air inlet 3111, and then flow through the mesh holes on the steaming net 33 into the upper steaming cavity 30a, thereby steaming the ingredients on the steaming net 33.

[0217] In some embodiments, the air outlet 3131 may be located above the steaming net 33. The air outlet 3131 may communicate 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 ingredients on the steaming net 33 and improving the steam cooking efficiency inside the steaming box 3.

[0218] In some embodiments, the steaming net 33 may be detachably erected inside the steaming box 3. In other embodiments, the steaming net 33 may also be integrally formed and erected inside the steaming box 3.

[0219] Refer to Figure 27 and Figure 28As shown, in some embodiments, support ribs 315 may protrude from the inner sidewall of the steaming box 3. The peripheral side edge of the steaming net 33 may be detachably supported on the support ribs 315. The support ribs 315 may be arranged to extend in the up and down direction. The support ribs 315 may extend upward from the inner bottom surface of the steaming box 3. The peripheral side edge of the steaming net 33 can be supported by the support ribs 315, and thus the steaming net 33 can be erected inside the steaming box 3, so that a certain preset distance is maintained between the steaming net 33 and the inner bottom surface of the steaming box 3.

[0220] In some embodiments, on the inner sidewall of the steaming box 3, there may be multiple support ribs 315. The multiple support ribs 315 are circumferentially spaced and arranged on the inner peripheral wall of the steaming box 3. The peripheral side edge of the steaming net 33 may be detachably supported on the multiple support ribs 315. By supporting different positions of the peripheral side edge of the steaming net 33 with the multiple support ribs 315, the stability of the steaming net 33 can be improved, and the steaming net 33 can be prevented from tipping over inside the steaming box 3.

[0221] It should be noted that the number of the support ribs 315 and the interval width between the support ribs 315 can be adjusted as needed, and no limitation is made here.

[0222] In some embodiments, the multiple support ribs 315 on the inner wall of the steaming box 3 can be divided into two groups. One group of support ribs 315 can be provided on the front sidewall inside the steaming box 3. The other group of support ribs 315 can be provided on the rear sidewall inside the steaming box 3. The two groups of support ribs 315 can support the front and rear side edges of the steaming net 33.

[0223] It should be noted that in other embodiments, among the two groups of support ribs 315, one group of support ribs 315 can be provided on the left sidewall inside the steaming box 3. The other group of support ribs 315 can be provided on the right sidewall inside the steaming box 3. The two groups of support ribs 315 can support the left and right side edges of the steaming net 33.

[0224] Refer to Figure 27 and Figure 28 As shown, in some embodiments, the support rib 315 may include a support portion 3151. The support portion 3151 may protrude from the inner sidewall of the steaming box 3. The top of the support portion 3151 can be used to support the peripheral side edge of the steaming net 33. When the steaming net 33 is placed inside the steaming box 3, the peripheral side edge of the steaming net 33 can be supported on the top of the support portion 3151, and thus the steaming net 33 can be stably erected inside the steaming box 3.

[0225] In some embodiments, the support rib 315 may include a spacer 3152. The spacer 3152 may be protruding on the inner side wall of the steam box 3. The spacer 3152 may be protruding above the top of the support portion 3151. The thickness of the spacer 3152 protruding from the inner wall of the steam box 3 may be less than the thickness of the support portion 3151 protruding from the inner wall of the steam box 3. When the peripheral edge of the steam net 33 is supported on the top of the support rib 315, the peripheral side wall of the steam net 33 can be against the spacer 3152, so that a gap is formed between the peripheral side wall of the steam net 33 and the inner side wall of the steam box 3. When steam enters the interior of the steam box 3, the steam in the upper steam chamber 30a and the lower steam chamber 30b can flow to each other through the gap between the peripheral edge of the steam net 33 and the inner wall of the steam box 3.

[0226] See also Figure 27 and Figure 28 As shown, in some embodiments, a handle hole 331 may be provided on the steaming net 33. The handle hole 331 may connect the upper and lower sides of the steaming net 33. When the steaming net 33 needs to be taken out from the steaming box 3, the user may insert a finger or chopsticks into the handle hole 331, and then the steaming net 33 may be easily taken out from the steaming box 3.

[0227] In some embodiments, two handle holes 331 may be provided. The two handle holes 331 may be spaced apart and disposed on opposite sides of the steaming net 33. It should be noted that the number, position and aperture of the handle holes 331 may be adjusted as required and are not limited here.
