[0102] In some embodiments, the heating module may include a heating fan 22. The heating fan 22 may be disposed within a fan housing 210. The heating fan 22 may be used to provide wind force, allowing air in the cooking cavity 20 to enter the fan housing 210, and allowing air in the fan housing 210 to enter the cooking cavity 20, thereby forming an air circulation between the cooking cavity 20 and the fan housing 210.

[0103] In some embodiments, the heating module may include a heating ring 23. The heating ring 23 may be disposed inside the fan compartment 210. The heating ring 23 may be annular in structure. The heating ring 23 may be circumferentially arranged around the heating fan 22. The heating ring 23 may heat the air inside the fan compartment 210. When the heating ring 23 and the heating fan 22 are in operation, the heating ring 23 may form hot air inside the fan compartment 210. The wind force of the heating fan 22 may transport the hot air inside the fan compartment 210 into the cooking cavity 20, thereby increasing the temperature inside the cooking cavity 20. The air inside the cooking cavity 20 may re-enter the fan compartment 210 under the action of the wind force of the heating fan 22 and be reheated by the heating ring 23, thereby forming a hot air circulation inside the cooking cavity 20 and the fan compartment 210.

[0104] See also Figure 5 ,and Figure 7 As shown, in some embodiments, the air guide 21 may be provided with an air inlet 211.

The heating module can heat the air in the fan compartment 210, and transport hot air to the cooking cavity 20 through the air outlet 212, thereby increasing the temperature in the cooking cavity 20. Specifically, the air in the fan compartment 210 can be heated by the heating ring 23. The wind force of the heating fan 22 can be used to transport the hot air in the fan compartment 210 to the cooking cavity 20 through the air outlet 212, so that the air in the cooking cavity 20 enters the fan compartment 210 through the air inlet 211 and is reheated by the heating ring 23, thereby realizing the hot air circulation between the fan compartment 210 and the cooking cavity 20.

[0109] See Figure 7 As shown, in some embodiments, an air outlet 212 may be provided on the upper side of the air guide 21.

[0133] See Figure 13and Figure 16 As shown, in some embodiments, the cooking device may include an exhaust connector 7. The exhaust connector 7 may be disposed through the rear wall of the inner pot 2. The front end of the exhaust connector 7 may be disposed within the fan compartment 210. The rear end of the exhaust connector 7 may protrude beyond the rear wall of the inner pot 2. When the steam box 3 is placed within the cooking cavity 20, the steam output pipe 313 may be disposed directly opposite the exhaust connector 7. The steam output pipe 313 may be connected to the exhaust connector 7, allowing the air within the steam box 3 to be discharged from the inner pot 2 through the air outlet 3131 and the exhaust connector 7.

[0134] In some embodiments, when the steam box 3 is placed inside the cooking cavity 20 , the steam output pipe 313 can be inserted into the exhaust connector 7 so that the air outlet 3131 is connected to the exhaust connector 7 .

[0135] It should be noted that, in some other embodiments, when the steam box 3 is placed inside the cooking cavity 20 , the exhaust connector 7 may also be inserted into the steam output pipe 313 , so that the air outlet 3131 is connected to the exhaust connector 7 .

[0136] See Figure 16 As shown, in some embodiments, a sealing sleeve 71 may be provided at the front end of the exhaust connector 7. The sealing sleeve 71 may be detachably mounted on the front end of the exhaust connector 7. The sealing sleeve 71 may have an annular structure. The sealing sleeve 71 may be arranged around the circumferential edge of the front end of the exhaust connector 7. A sealing hole (not shown) may be provided in the center of the sealing sleeve 71. The sealing hole may be arranged at the axis of the exhaust connector 7.

[0137] When the steam box 3 is placed in the cooking cavity 20, the steam output pipe 313 can be inserted into the sealing hole. The steam output pipe 313 can pass through the sealing hole and be inserted into the front end of the exhaust connector 7, so that the gas outlet 3131 is connected to the exhaust connector 7. When the steam output pipe 313 is inserted into the sealing hole, the sealing sleeve 71 can be installed around the outer periphery of the steam output pipe 313, thereby sealing the gap between the outer wall of the steam output pipe 313 and the inner wall of the exhaust connector 7. The sealing sleeve 71 seals the gap between the outer wall of the steam output pipe 313 and the inner wall of the exhaust connector 7, ensuring that steam is completely discharged to the outside of the inner pot 2 and does not overflow into the cooking cavity 20.

[0138] See Figure 9 and Figure 16 As shown, in some embodiments, the cooking device may include an exhaust pipe (not shown). The exhaust pipe may be disposed outside the inner pot 2. The lower end of the exhaust pipe may be connected to the outer end of the exhaust connector 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 connector 7, and the exhaust pipe in sequence.

[0139] 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 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 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.

[0140] It should be noted that, in some other embodiments, the lower end of the exhaust pipe may also be directly connected to the outer end of the exhaust joint 7 .

[0141] See Figure 4 and Figure 9 As shown, in some embodiments, the cooking device may include a condenser 8. The condenser 8 may be provided on the exhaust pipe. The condenser 8 may be located above the exhaust connector 7. The condenser 8 may be located above the transfer tube 75. The condenser 8 can condense the gas flowing through the exhaust pipe, thereby improving the condensation performance of the exhaust gas. The condensed water after condensation can flow downward along the exhaust pipe, and flow back into the steaming box 3 through the transfer tube 75, the exhaust connector 7, and the air outlet 3131. The water that flows back into the steaming box 3 can be stored in the bottom area of the steaming box 3, and can be converted into steam again under the action of the high temperature inside the steaming box 3, thereby improving the utilization rate of the condensed water.

[0142] 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 can be connected to the exhaust connector 7 through the adapter tube 75. The top of the first exhaust section can be connected to one end of the condenser 8. One end of the second exhaust section can be connected to the other end of the condenser 8. Therefore, the gas in the steam box 3 can enter the condenser 8 through the air outlet 3131, the exhaust connector 7, and the first exhaust section for condensation, and the condensed gas can be discharged through the second exhaust section. The condensed water formed in the condensation chamber can flow downward and flow back into the steam box 3 through the exhaust connector 7 and the air outlet 3131.

[0143] In some embodiments, the end of the exhaust pipe away from the exhaust connector 7 can be extended into the heat dissipation duct. Therefore, the gas condensed by the condenser 8 can be discharged into the heat dissipation duct through the exhaust pipe, thereby improving the condensation performance of the steam or gas discharged from the steam box 3.

[0144] See Figure 14 and Figure 15As shown, in some embodiments, the steaming box 3 may include a steaming net 33. The steaming net 33 may be installed inside the steaming box 3. The steaming net 33 may have 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 food to be steamed. The steaming net 33 may separate the interior space of the steaming box 3 into an upper steaming chamber 30a and a lower steaming chamber 30b. The upper steaming chamber 30a may be formed above the steaming net 33. The lower steaming chamber 30b may be formed below the steaming net 33.

[0145] When steam enters the steam box 3 through the air inlet 3111, it can enter the upper steaming chamber 30a and the lower steaming chamber 30b. The steam in the upper steaming chamber 30a and the lower steaming chamber 30b can flow through the mesh of the steaming net 33, thereby increasing the contact area between the steam and the food on the steaming net 33, thereby improving the steam cooking efficiency in the steam box 3.

[0146] It should be noted that, in some other embodiments, the food can also be placed inside the lower steaming chamber 30b for steaming.

[0147] In some embodiments, the air inlet 3111 can be located below the steaming net 33. The air inlet 3111 can communicate with the lower steaming chamber 30b. When the steam box 3 is pushed into the cooking chamber 20, the air inlet 3111 can connect to the steam connector 5. The steam generator 4 can guide steam through the steam connector 5 and the air inlet 3111 into the lower steaming chamber 30b, and then flow through the mesh of the steaming net 33 into the upper steaming chamber 30a, thereby steaming and cooking the food on the steaming net 33.

[0148] In some embodiments, the air outlet 3131 can be located above the steaming net 33. The air outlet 3131 can communicate with the upper steaming chamber 30a. When the steam box 3 is inserted into the cooking chamber 20, the air outlet 3131 can connect to the exhaust connector 7, allowing air and steam in the upper steaming chamber 30a to exit the steam box 3 and inner pot 2 through the air outlet 3131 and exhaust connector 7. By allowing steam to enter the lower steaming chamber 30b and exit the upper steaming chamber 30a, the steam can pass through the steaming net 33, thereby ensuring that the steam can steam and cook the ingredients on the steaming net 33, thereby improving the steam cooking efficiency within the steam box 3.

[0149] 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 mounted inside the steaming box 3.

[0150] See Figure 14 and Figure 16As shown, in some embodiments, support ribs 315 may be protruding from the inner sidewall of the steam box 3. The peripheral edges of the steam net 33 may be detachably supported on the support ribs 315. The support ribs 315 may extend in the vertical direction. The support ribs 315 may extend upward from the inner bottom surface of the steam box 3. The support ribs 315 can support the peripheral edges of the steam net 33, allowing the steam net 33 to be installed inside the steam box 3, maintaining a predetermined distance between the steam net 33 and the inner bottom surface of the steam box 3.

[0151] In some embodiments, multiple support ribs 315 may be provided on the inner sidewall of the steam box 3. The multiple support ribs 315 are circumferentially spaced apart on the inner circumferential wall of the steam box 3. The lateral edges of the steam net 33 may be detachably supported on the multiple support ribs 315. The multiple support ribs 315 support the lateral edges of the steam net 33 at different locations, thereby improving the stability of the steam net 33 and preventing it from tipping over inside the steam box 3.

[0152] It should be noted that the number of the support ribs 315 and the spacing width between the support ribs 315 can be adjusted as needed and are not limited here.

[0153] In some embodiments, the plurality of support ribs 315 on the inner wall of the steam box 3 can be divided into two groups. One group of support ribs 315 can be provided on the front side wall of the steam box 3. The other group of support ribs 315 can be provided on the rear side wall of the steam box 3. Both groups of support ribs 315 can support the front and rear edges of the steaming net 33.

[0154] It should be noted that, in other embodiments, one set of the two sets of support ribs 315 can be provided on the left wall of the steam box 3, and the other set of support ribs 315 can be provided on the right wall of the steam box 3. The two sets of support ribs 315 can support the left and right edges of the steaming net 33.

[0155] See Figure 14 and Figure 16 As shown, in some embodiments, the support ribs 315 may include support portions 3151. The support portions 3151 may be protruding from the inner sidewall of the steam box 3. The top of the support portions 3151 may be used to support the peripheral edges of the steaming net 33. When the steaming net 33 is placed in the steaming box 3, the peripheral edges of the steaming net 33 may be supported by the top of the support portions 3151, thereby ensuring that the steaming net 33 can be stably installed in the steaming box 3.

[0156] In some embodiments, the support ribs 315 may include a spacer 3152. The spacer 3152 may be protruding from the inner 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 ribs 315, the peripheral side wall of the steam net 33 can be abutted against the spacer 3152, so that a gap is formed between the peripheral side wall of the steam net 33 and the inner wall of the steam box 3. When steam enters the interior of the steam box 3, the steam in the upper steaming chamber 30a and the lower steaming 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.

[0157] See Figure 14 As shown, in some embodiments, the steaming net 33 may be provided with a handle hole 331. The handle hole 331 may connect the upper and lower sides of the steaming net 33. When the steaming net 33 needs to be removed from the steaming box 3, the user can insert a finger or chopsticks into the handle hole 331 to conveniently remove the steaming net 33 from the steaming box 3.

[0158] In some embodiments, there may be two handle holes 331. 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 needed and are not limited here.

[0159] See Figure 10 、 Figure 14 and Figure 14 As shown, in some embodiments, the steaming box 3 may include a box body 31 and a box lid 32. The top of the box body 31 may be provided with an opening. The box lid 32 may be removably mounted on the top opening of the box body 31. When the box lid 32 is mounted on the top of the box body 31, a sealed cavity may be formed inside the steaming box 3. The steaming net 33 may be mounted inside the box body 31. The air inlet 3111 and the air outlet 3131 may be respectively disposed on the rear side wall of the box body 31.

[0160] When the steam box 3 is pushed backward into the cooking cavity 20 , the air inlet 3111 can be connected to the steam connector 5 , and the air outlet 3131 can be connected to the exhaust connector 7 .

[0161] It should be noted that, in some embodiments, the air inlet 3111 and the air outlet 3131 may also be provided on other side walls of the box body 31 .

[0164] In some embodiments, the steam generator 4 may be provided with a first heating tube 43. The first heating tube 43 may be arranged in a sidewall of the steam generating chamber 40a. The first heating tube 43 is used to heat water within the steam generating chamber 40a to generate steam. The steam generated within the steam generating chamber 40a may be delivered into the cooking cavity 20 or into the interior of the steam box 3 via the first output port and the steam connector 5.

[0165] See also Figure 19 and Figure 20 As shown, in some embodiments, a pipe portion 401 may be protruding from the side wall of the steam generating chamber 40a. The first heating pipe 43 may be disposed within the pipe portion 401. When the first heating pipe 43 is in operation, the heat generated by the first heating pipe 43 may be transferred to the water in the steam generating chamber 40a through the pipe portion 401, thereby heating the water in the steam generating chamber 40a and converting the water into steam.

[0166] In some embodiments, the first heating tube 43 may be buried inside the pipe portion 401 so that the first heating tube 43 does not come into contact with the water in the steam generating chamber 40a, thereby preventing the first heating tube 43 from being corroded or rusted by water.

[0167] It should be noted that, in other embodiments, the first heating tube 43 may also be arranged inside the steam generating chamber 40a.

[0168] See also Figure 19 、 Figure 20 and Figure 21As shown, in some embodiments, the steam generator 4 may include a steam heating chamber 40b.

Steam generated within the steam generating chamber 40a may enter the steam heating chamber 40b. After secondary heating by the second heating pipe 44, the heated steam is delivered into the cooking cavity 20 or into the steam box 3 through the first output port and the steam connector 5. Secondary heating of the steam flowing through the steam heating chamber 40b by the second heating pipe 44 can significantly increase the temperature of the steam outputted from the first output port, thereby increasing the steam temperature within the steam box 3 and improving cooking efficiency within the steam box 3.

[0169] In some embodiments, a first dividing rib 402 may be provided within the steam generator 4. The first dividing rib 402 may extend laterally. The first dividing rib 402 may separate the interior of the steam generator 4 into a steam generation chamber 40a and a steam heating chamber 40b. The steam heating chamber 40b may be formed above the first dividing rib 402, and the steam generation chamber 40a may be formed below the first dividing rib 402, such that the steam heating chamber 40b is positioned above the top of the steam generation chamber 40a.

[0170] In some embodiments, a notch 4021 may be provided on the first dividing rib 402. The top area of the steam generating chamber 40a may be connected to the bottom area of the steam heating chamber 40b through the notch 4021.

[0171] In some embodiments, the notch 4021 may be provided at one end of the first dividing rib 402. The notch 4021 may be formed between the end of the first dividing rib 402 and the inner wall of the steam generator 4. It should be noted that in other embodiments, the notch 4021 may also be provided at other locations of the first dividing rib 402.

[0172] See also Figure 19 、 Figure 20 and Figure 21As shown, in some embodiments, a curved steam channel (not shown in the figure) can be formed in the steam heating chamber 40b. One end of the steam channel can be connected to the top area of the steam generating chamber 40a through the notch 4021. The other end of the steam channel can be connected to the first output port of the steam generator 4, that is, the other end of the steam channel can be connected to the first output pipe 41 of the steam generator 4. At least part of the pipeline of the second heating pipe 44 can extend into the steam channel. Therefore, the steam formed in the steam generating chamber 40a can enter the steam channel, and the steam in the steam channel is heated by the second heating pipe 44, so that the steam can be heated again, thereby increasing the steam temperature in the steam channel. The steam heated in the steam channel can be transported into the cooking cavity 20 or into the steam box 3 through the first output port and the steam connector 5.

[0173] In some embodiments, the steam channel can be a continuous S-shaped or U-shaped channel structure, thereby increasing the length of the steam channel, fully utilizing the internal space of the steam heating chamber 40b, and increasing the contact area between the second heating tube 44 and the steam in the steam channel, thereby increasing the steam temperature in the steam channel. In other embodiments, the steam channel can be a continuous C-shaped structure or a curved channel structure of other shapes.

[0174] See also Figure 19 、 Figure 20 and Figure 21 As shown, in some embodiments, a second dividing rib 403 extending transversely may be provided in the steam heating chamber 40b. A transverse channel 404 may be formed on the upper and lower sides of the second dividing rib 403, respectively. A vent 4031 may be provided at one end of the second dividing rib 403. The vent 4031 can connect the transverse channels 404 on the upper and lower sides of the second dividing rib 403, so that one end of the upper and lower transverse channels 404 is connected to form a steam channel. The transversely extending second dividing rib 403 can be used to separate the steam heating chamber 40b into at least two adjacent transverse channels 404. The internal space of the steam heating chamber 40b can be fully utilized. The ends of the adjacent transverse channels 404 can be connected through the vent 4031 to form a curved steam channel, thereby increasing the length of the steam channel.

[0175] In some embodiments, the steam heating chamber 40b may be provided with a plurality of second dividing ribs 403. The plurality of second dividing ribs 403 may be arranged vertically and sequentially. The plurality of second dividing ribs 403 may divide the steam heating chamber 40b into a plurality of transverse channels 404. The plurality of transverse channels 404 may be arranged vertically and sequentially. The ends of the plurality of transverse channels 404 may be connected sequentially through corresponding vents 4031, thereby forming a curved steam channel.

[0176] In some embodiments, between any two adjacent second dividing ribs 403, the vent 4031 on one second dividing rib 403 is located at one transverse end. The vent 4031 on the other second dividing rib 403 is located at the other transverse end, so that the multiple transverse channels 404 are sequentially connected to form a curved steam channel. Therefore, the transverse channels 404 in the two second dividing ribs 403 can connect to the upper transverse channel 404 through the vent 4031 at one end, and can connect to the lower transverse channel 404 through the vent 4031 at the other end, thereby connecting the multiple transverse channels 404 end to end, forming a curved steam channel.

[0177] See Figure 21 As shown, in some embodiments, among the multiple second dividing ribs 403 in the steam heating chamber 40b, the transverse channel 404 formed between the lowest second dividing rib 403 and the first dividing rib 402 is a first transverse channel 4041. That is, a first transverse channel 4041 may be formed between a first dividing rib 402 and an adjacent second dividing rib 403. There is only one first transverse channel 4041. The first transverse channel 4041 may be located in the bottom area of the steam heating chamber 40b. The first transverse channel 4041 may be located at the bottom end of the steam channel. That is, the bottom end of the steam channel may be the first transverse channel 4041. One end of the first transverse channel 4041 may connect to the top area of the steam generating chamber 40a through a notch 4021 at the end of the first dividing rib 402. Therefore, the bottom end of the steam channel may be connected to the top area of the steam generating chamber 40a in a curved manner through the first transverse channel 4041 and the notch 4021.

[0178] In some embodiments, the vent 4031 on the second dividing rib 403 adjacent to the first dividing rib 402 is located at the end of the first transverse channel 4041 away from the notch 4021. The end of the first transverse channel 4041 away from the notch 4021 can be connected to the transverse channel 404 above it through the vent 4031. Therefore, one end of the first transverse channel 4041 can be connected to the top area of the steam generating chamber 40a through the notch 4021, and the other end of the first transverse channel 4041 can be connected to the transverse channel 404 above it through the vent 4031.

[0179] See Figure 21As shown, in some embodiments, among the multiple second dividing ribs 403 in the steam heating chamber 40b, the transverse channel 404 formed between the topmost second dividing rib 403 and the top inner wall of the steam heating chamber 40b is a second transverse channel 4042. That is, a second transverse channel 4042 can be formed between the top inner wall of the steam heating chamber 40b and an adjacent second dividing rib 403. There is only one second transverse channel 4042. The second transverse channel 4042 can be located in the top area of the steam heating chamber 40b. The second transverse channel 4042 can be located at the top of the steam channel. That is, the top of the steam channel can be the second transverse channel 4042. The output of the steam generator 4 is located at one end of the second transverse channel 4042, allowing one end of the second transverse channel 4042 to communicate with the output of the steam generator 4. The vent 4031 on the second dividing rib 403 adjacent to the top inner wall of the steam heating chamber 40b is located at the other end of the second transverse channel 4042. Therefore, one end of the second transverse channel 4042 can be connected to the transverse channel 404 below it through the vent 4031, and then bendably connected to the first transverse channel 4041. The other end of the second transverse channel 4042 can be connected to the outside through the output port of the steam generator 4, so that the top end of the steam channel can be connected to the output port of the steam generator 4 through the second transverse channel 4042.

[0180] See Figure 21 As shown, in some embodiments, among the plurality of second dividing ribs 403 of the steam heating chamber 40b, the transverse channels 404 formed between adjacent second dividing ribs 403 may be third transverse channels 4043. Figure 19 As shown, two second dividing ribs 403 are provided within the steam heating chamber 40b, with only one third transverse channel 4043 formed between the two second dividing ribs 403. One end of the third transverse channel 4043 can connect to the first transverse channel 4041 below it via a vent 4031, and the other end of the third transverse channel 4043 can connect to the second transverse channel 4042 above it via another vent 4031. This allows the first transverse channel 4041 to be connected to the second transverse channel 4042 through at least one third transverse channel 4043, thereby forming a curved steam channel. In this case, the steam channel can be formed by the curved connection of one first transverse channel 4041, one second transverse channel 4042, and at least one third transverse channel 4043.

[0181] It should be noted that, in some embodiments, the steam channel may also be formed by a first transverse channel 4041 and a second transverse channel 4042 that are connected in a curved manner.

[0182] It should be noted that, in some other embodiments, as the number of the second dividing ribs 403 increases, the number of the third transverse channels 4043 may increase accordingly. The plurality of third transverse channels 4043 may be connected in a bent manner end to end.

[0183] See also Figure 19 、 Figure 20 and Figure 21 As shown, in some embodiments, the second heating pipe 44 may include a straight pipe section 441. The straight pipe section 441 may be arranged in a long strip shape. The straight pipe section 441 may be suspended and extended into the transverse channel 404. The extension direction of the straight pipe section 441 may be consistent with the extension direction of the transverse channel 404. By arranging the straight pipe section 441 in the transverse channel 404 in a suspended and parallel manner, the contact area between the straight pipe section 441 and the steam in the transverse channel 404 can be increased, and the contact area between the second heating pipe 44 and the steam in the steam channel can be increased, thereby improving the heating efficiency of the steam in the steam channel, which is beneficial to increasing the temperature of the steam output by the steam generator 4.

[0184] In some embodiments, the second heating pipe 44 may include multiple straight pipe sections 441. The multiple straight pipe sections 441 may be arranged in parallel and spaced apart within the steam heating chamber 40b. The multiple straight pipe sections 441 may be located in the same or different transverse channels 404 within the steam passage. The number of straight pipe sections 441 may be adjusted as needed and is not limited herein.

[0185] In some embodiments, the second heating pipe 44 may include a curved pipe section 442. The curved pipe section 442 may be disposed between two adjacent straight pipe sections 441. One end of the curved pipe section 442 may be connected to one end of a straight pipe section 441. The other end of the curved pipe section 442 may be connected to one end of another adjacent straight pipe section 441. The curved pipe section 442 may have a U-shaped or C-shaped structure.

[0186] In some embodiments, the second dividing rib 403 may be provided with a through-hole 4032 , through which a curved pipe section 442 may be passed, such that both ends of the curved pipe section 442 may be connected to the straight pipe sections 441 on the upper and lower sides of the second dividing rib 403 .

[0187] In some embodiments, the vent 4031 on the second dividing rib 403 can be spaced apart from the through-hole 4032. The vent 4031 on the second dividing rib 403 can also be connected to the through-hole 4032 to form a whole.

[0188] See also Figures 16 to 19As shown, in some embodiments, the steam generator 4 may have a first outer wall (not shown). The first input port and the first output port of the steam generator 4 may be spaced apart on the first outer wall of the steam generator 4. That is, the first input pipe 42 and the first output pipe 41 may be spaced apart on the first outer wall of the steam generator 4. The first input pipe 42 may be located at the bottom end of the first outer wall. The first output pipe 41 may be located at the top end of the first outer wall.

[0189] In some embodiments, one end of the first dividing rib 402 may be connected to the first outer sidewall of the steam generator 4. The notch 4021 may be located at the end of the first dividing rib 402 away from the first outer sidewall of the steam generator 4. Thus, the internal space of the steam generator 4 can be fully utilized, facilitating the layout of the steam passages within the steam generating chamber 40a and the steam heating chamber 40b, increasing the length of the steam passages, and improving the heating efficiency within the steam generating chamber 40a and the steam heating chamber 40b.

[0190] See also Figure 17 、 Figure 18 and Figure 19 As shown, in some embodiments, the steam heating chamber 40b can be filled with a void heat-conducting material. The void heat-conducting material can be filled in the steam channel. The steam in the steam channel can flow in the voids within the void heat-conducting material. The void heat-conducting material can be made of a high-temperature-resistant, high-thermal-conducting void material, such as a stainless steel wire mesh or other porous structure material. The second heating tube 44 can be inserted into the void heat-conducting material. The heat generated by the second heating tube 44 can be transferred to the void heat-conducting material. The void structure within the void heat-conducting material can increase the heat exchange area with the steam, which is conducive to raising the steam temperature. At the same time, the heat radiation of the second heating tube 44 to the outer shell of the steam generator 4 can be reduced, thereby lowering the temperature of the outer shell of the steam generator 4.

[0192] See also Figure 18 、 Figure 22 and Figure 24 As shown, in some embodiments, the steam generator 4 may include a housing 45 and a cover plate 46. One side of the housing 45 may be provided with an opening. The cover plate 46 may cover the opening on one side of the housing 45. The cover plate 46 and the interior of the housing 45 may enclose a steam generation chamber 40a and a steam heating chamber 40b.

[0193] See Figure 22 and Figure 24 As shown, in some embodiments, the first dividing rib 402 can be divided into two parts. One part of the first dividing rib 402 can be protruded from the interior of the housing 45. The other part of the first dividing rib 402 can be protruded from the cover plate 46. When the cover plate 46 is installed on the housing 45, the two parts of the first dividing rib 402 can be spliced together to separate the internal space of the steam generator 4 into a steam generation chamber 40a and a steam heating chamber 40b.

[0194] In some embodiments, the notch 4021 on the first dividing rib 402 may be formed at the end of the first dividing rib 402 in the housing 45 , or may be formed at the end of the first dividing rib 402 on the cover plate 46 .

[0195] In some embodiments, a portion of the notch 4021 may be disposed on the first dividing rib 402 inside the housing 45. Another portion of the notch 4021 may be disposed on the first dividing rib 402 inside the cover 46. When the housing 45 and the cover 46 are assembled, the two portions of the notch 4021 may be combined to form the entire notch 4021.

[0196] See Figure 22 and Figure 24 As shown, in some embodiments, the second dividing rib 403 can be divided into two parts. One part of the second dividing rib 403 can be protruded from the interior of the housing 45. The other part of the second dividing rib 403 can be protruded from the cover plate 46. When the cover plate 46 is placed on the housing 45, the two parts of the second dividing rib 403 can be spliced together to divide the interior space of the steam heating chamber 40b into a curved steam channel.

[0197] In some embodiments, the vent 4031 on the second dividing rib 403 may be formed at one end of the second dividing rib 403 in the housing 45 , or may be formed at one end of the second dividing rib 403 on the cover plate 46 .

[0198] In some embodiments, a portion of the vent 4031 can be disposed on the second dividing rib 403 inside the housing 45. Another portion of the vent 4031 can be disposed on the second dividing rib 403 inside the cover 46. When the housing 45 and the cover 46 are assembled, the two portions of the vent 4031 can be combined to form the entire vent 4031.

[0199] In some embodiments, a portion of the opening 4032 can be disposed on the second dividing rib 403 within the housing 45. Another portion of the opening 4032 can be disposed on the second dividing rib 403 of the cover 46. When the housing 45 and the cover 46 are assembled, the two portions of the opening 4032 can be combined to form the entire opening 4032.

[0200] See Figure 18 and Figure 24 As shown, in some embodiments, the steam generator 4 may include a sealing ring 47. The sealing ring 47 may be arranged around the peripheral edge of the opening of the shell 45. The sealing ring 47 may be clamped between the shell 45 and the cover plate 46, thereby sealing the steam generation chamber 40a and the steam heating chamber 40b through the sealing ring 47.

[0202] See also Figure 25 and Figure 26 As shown, in some embodiments, the steam module may include a steam heater 6. The steam heater 6 can be used to reheat the steam generated by the steam generator 4 to produce high-temperature steam. The steam heater 6 can be located inside the housing 1. The steam heater 6 can also be located outside the inner pot 2. The steam heater 6 can also be located between the output end of the steam generator 4 and the steam connector 5.

[0203] The output end of the steam generator 4 can be connected to the input end of the steam heater 6 via a steam pipeline. The output end of the steam heater 6 can also be connected to the steam connector 5 via a steam pipeline. The steam generated by the steam generator 4 can be delivered to the steam heater 6. The steam heater 6 can reheat the steam flowing through the steam heater 6 to increase the steam temperature, thereby generating high-temperature steam. The high-temperature steam heated by the steam heater 6 can be delivered into the steam box 3 through the steam connector 5 and the air inlet 3111, thereby increasing the steam temperature inside the steam box 3 and improving the steam cooking efficiency inside the steam box 3.

[0204] In some embodiments, a second input pipe 61 may be protruding from the outer wall of the steam heater 6. The second input pipe 61 may serve as the input end of the steam heater 6. A second input port 611 may be formed within the second input pipe 61, serving as the input port for the steam generator 4. The second input pipe 61 may be connected to the first output pipe 41 of the steam generator 4 via a steam pipeline. In other words, the second input port 611 is connected to the first output port of the steam generator 4 via a steam pipeline. Therefore, the high-temperature steam generated within the steam generator 4 can enter the steam heater 6 via the first output port and the second input port 611 for secondary heating.

[0205] In some embodiments, a second output tube 62 may be protruding from the outer wall of the steam heater 6. The second output tube 62 may serve as the output end of the steam heater 6. A second output port 621 may be formed within the second output tube 62, serving as the output port of the steam heater 6. The second output tube 62 may be connected to the steam connector 5 via a steam pipeline, such that the second output port 621 is connected to the steam connector 5. The high-temperature steam heated in the steam heater 6 may be delivered into the cooking cavity 20 or into the interior of the steam box 3 via the second output port 621, the steam pipeline, and the steam connector 5.

[0207] See also Figure 27 、 Figure 28 and Figure 30 As shown, in some embodiments, a partition 63 may be provided within the steam heater 6. The partition 63 may separate the interior of the steam heater 6 into a first steam heating chamber 60a and a second steam heating chamber 60b. The partition 63 may be provided with a vent 631. The vent 631 may connect the first steam heating chamber 60a and the second steam heating chamber 60b. The input end of the steam heater 6 may be in communication with the first steam heating chamber 60a, that is, the second input port 611 may be in communication with the first steam heating chamber 60a. The output end of the steam heater 6 may be in communication with the second steam heating chamber 60b, that is, the second output port 621 may be in communication with the second steam heating chamber 60b.

[0208] When steam generated by the steam generator 4 is delivered to the steam heater 6, it first enters the first steam heating chamber 60a through the second input port 611 for heating, then enters the second steam heating chamber 60b through the vent 631 for further heating, and is then delivered to the steam box 3 through the second output port 621, the steam connector 5, and the air inlet 3111. After the steam is heated in the first and second steam heating chambers 60a, 60b, its temperature is increased, producing higher-temperature steam. This, in turn, increases the temperature of the steam entering the steam box 3, thereby improving the steam cooking efficiency within the steam box 3.

[0209] In some embodiments, a third heating tube 64 may be provided in the steam heater 6. The third heating tube 64 may include a first heating portion 641 and a second heating portion 642. The first heating portion 641 may extend into and be arranged in the first steam heating chamber 60a. The first heating portion 641 may be used to heat the first steam heating chamber 60a. The second heating portion 642 may extend into and be arranged in the second steam heating chamber 60b. The second heating portion 642 may be used to heat the second steam heating chamber 60b. When steam enters the first steam heating chamber 60a, it may be heated by the first heating portion 641. The heated steam may enter the second steam heating chamber 60b through the vent 631 and then be heated by the second heating portion 642.

[0210] It should be noted that, in other embodiments, the steam heater 6 may also be provided with two third heating tubes 64. One third heating tube 64 may be disposed in the first steam heating chamber 60a for independently heating the first steam heating chamber 60a. The other third heating tube 64 may be disposed in the second steam heating chamber 60b for independently heating the second steam heating chamber 60b.

[0211] See also Figure 27 and Figure 28 As shown, in some embodiments, the first heating portion 641 and the second heating portion 642 can be bent and connected as one piece. A through hole can be provided on the partition 63. The first heating portion 641 is bent and connected to the second heating portion 642 through the through hole.

[0212] See also Figure 27 and Figure 28 As shown, in some embodiments, the second input pipe 61 and the second output pipe 62 can be disposed on opposite sides of the partition 63, so that the second input port 611 and the second output port 621 can be disposed on opposite sides of the partition 63. The second input pipe 61 and the second input port 611 therein can be directly connected to the first heating chamber. The second output pipe 62 and the second output port 621 therein can be directly connected to the second heating chamber.

[0213] See also Figure 25 and Figure 26 As shown, in some embodiments, the second input pipe 61 and the second output pipe 62 can be respectively protruded from the first outer wall (not shown) of the steam heater 6. The second input pipe 61 and the second output pipe 62 can be respectively disposed at opposite ends of the first outer wall of the steam heater 6, thereby increasing the path length of the steam within the first steam heating chamber 60a and the second steam heating chamber 60b, thereby increasing the contact area between the steam and the third heating pipe 64, and facilitating an increase in the temperature of the steam output by the steam heater 6.

[0214] See also Figure 27 and Figure 28As shown, in some embodiments, the vent 631 on the partition 63 can be arranged on a side of the partition 63 away from the first outer sidewall of the steam heater 6. Therefore, when steam enters the first steam heating chamber 60a through the second input port 611 and then flows to the vent 631, the steam path length in the first steam heating chamber 60a can be increased, allowing the steam to fully contact and be heated by the first heating portion 641 of the third heating tube 64, thereby facilitating the increase of the steam temperature in the first steam heating chamber 60a.

[0215] Similarly, when the steam enters the second steam heating chamber 60b through the air vent 631 and then flows to the second output port 621, the path length of the steam in the second steam heating chamber 60b can be increased, so that the steam can fully contact and be heated by the second heating part 642 of the third heating tube 64, which is beneficial to increase the steam temperature in the second steam heating chamber 60b, and further help to increase the steam temperature output by the steam heater 6.

[0216] See also Figure 27 and Figure 28 As shown, in some embodiments, the partition 63 may be provided with a plurality of vent holes 631. The plurality of vent holes 631 may be sequentially and spaced apart on a side of the partition 63 away from the first outer sidewall of the steam heater 6. The plurality of vent holes 631 may be sequentially and spaced apart on a side of the partition 63 away from the second input pipe 61 and the second output pipe 62.

[0217] Multiple air 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, so that the steam in different areas of the first steam heating chamber 60a can enter the second steam heating chamber 60b through different air holes 631, so that the steam in each area of the first steam heating chamber 60a can flow and be heated by the first heating part 641 of the third heating tube 64, thereby improving the uniformity of the steam temperature in the first steam heating chamber 60a.

[0218] Similarly, the steam in the first steam heating chamber 60a can enter different areas of the second steam heating chamber 60b through different air vents 631, so that the steam in each area of the second steam heating chamber 60b can flow and be heated by the second heating part 642 of the third heating tube 64, thereby improving the uniformity of the steam temperature in the second steam heating chamber 60b.

[0219] It should be noted that the number of the vent holes 631 on the partition 63 can be adjusted as needed and is not limited here.

[0220] See also Figure 25 and Figure 26As shown, in some embodiments, the second input pipe 61 can be located in the top region of the first outer wall of the steam heater 6. The second output pipe 62 can be located in the bottom region of the first outer wall of the steam heater 6. Because steam is relatively light, the steam generated by the steam generator 4 can first enter the top region of the first steam heating chamber 60a through the second input pipe 61, and then gradually diffuse throughout the first steam heating chamber 60a. After being heated in the first steam heating chamber 60a, the steam diffuses through the vents 631 throughout the second steam heating chamber 60b, and then flows out of the second steam heating chamber 60b through the second output pipe 62 in the bottom region. During this steam flow process, the steam can flow fully through the first and second steam heating chambers 60a, significantly increasing the path length of the steam within the first and second steam heating chambers 60a, 60b, and thereby increasing the contact area between the steam and the third heating pipe 64, which helps to increase the temperature of the steam output by the steam heater 6.

[0221] See also Figure 27 and Figure 30 As shown, in some embodiments, the steam heater 6 can be filled with a void heat-conducting material (not shown in the figure). The void heat-conducting material can be a void material that is resistant to high temperature and has high thermal conductivity, such as a stainless steel wire mesh or other porous structure material. The void heat-conducting material can be filled in the first steam heating chamber 60a. The steam in the first steam heating chamber 60a can flow in the voids in the void heat-conducting material. The first heating part 641 of the third heating tube 64 can be passed through the void heat-conducting material in the first steam heating chamber 60a. The heat generated by the first heating part 641 can be transferred to the void heat-conducting material. By utilizing 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 heat radiation of the first heating part 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.

[0222] See also Figure 28 and Figure 30 As shown, in some embodiments, a void heat-conducting material can be filled in the second steam heating chamber 60b. The steam in the second steam heating chamber 60b can flow in the voids in the void heat-conducting material. The second heating portion 642 of the third heating tube 64 can be inserted into 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 utilizing the void structure in the void heat-conducting material, the heat exchange area with the steam can be increased, which is conducive to raising the steam temperature. At the same time, the heat radiation of the second heating portion 642 to the outer shell of the steam heater 6 can be reduced, thereby lowering the temperature of the outer shell of the steam heater 6.
