The outer shell 16, the middle plate 17, and the base 18 together form an inner pot receiving portion. The inner pot heating device 5 can be disposed between the base 18 and the bottom of the inner pot 4 and connected to the base 18, so it is also called a bottom heating device. Alternatively, another inner pot heating device 5 can be disposed between the outer shell 16 and the side of the inner pot 4, so it is also called a side heating device.

[0090] The cooking appliance 1 of the present application also has the function of steam heating. High-temperature steam can be delivered into the cooking cavity to heat and moisten the food in the cooking cavity. For example, high-temperature steam can be supplied to the cooking cavity during the holding stage to keep the food such as rice moist and prevent the food from drying out and turning yellow. Specifically, the cooking appliance 1 further comprises a steam generating device 40 for generating steam. In order to deliver the steam to the cooking cavity, the cover body 3 is provided with a cooking steam supply passage P11 which communicates with the cooking cavity.

Alternatively, the steam docking cover 30 is a separate component from the cover plate seat 15 and can be connected to the seat support portion 21 by welding, fasteners such as screws, or other suitable means. The steam docking cover 30 can be removed from the cover body 3 together with the detachable cover assembly 13, so that the steam docking cover 30 can be cleaned to prevent dirt on the steam docking cover 30 from contaminating the steam. The steam docking cover 30 and the detachable cover assembly 13 are removed in one step, which simplifies the process and improves efficiency.

[0096] The steam docking cover 30 is also provided with a steam docking sealing member 31 for forming a seal between the water container 41 and the steam docking cover 30 when the cover body 3 is closed. The steam docking sealing member 31 abuts against the top of the water container 41 that forms the top opening 43 when the cover body 3 is in the closed position. With the aid of the steam docking sealing member 31, a seal can be formed between the steam docking cover 30 and the top of the water container 41 to prevent steam from escaping from the gap between them, thereby improving the utilization rate of steam.

[0097] When cooking, the food and water in the inner pot 4 are heated to produce steam. In order to exhaust the steam generated during cooking to the outside environment, the cover body 3 is also provided with a cooking steam exhaust channel P12 (see Figure 2 ) that communicates with the cooking chamber and an exhaust channel. Steam in the cooking chamber can first enter the cooking steam exhaust channel P12 and then be exhausted to the outside environment through the exhaust channel.

[0098] In order to simplify the structure and optimize the use of the space inside the cover 3, the steam supply channel P11 for the steam for the cooking and the steam exhaust channel P12 for the steam for cooking are formed by one component in the present application, instead of being formed by different components. Specifically, the cover 3 further comprises a steam channel component 50 for forming the steam supply channel P11 for the steam for the cooking and the steam exhaust channel P12 for the steam for cooking. The two channels are independent of each other and not connected. The steam channel component 50 is located on the upper side of the cover plate 14 and the lower side of the inner liner 9. As shown in Figure 3 the inner liner 9 has a recess 19 for accommodating the steam channel component 50. At least part of the steam channel component 50 is accommodated in the recess 19. The size and shape of the recess 19 are adapted to the outer contour of the steam channel component 50.

[0099] The steam channel component 200 is further provided with a cooking steam inlet 201 and a cooking steam outlet 202 which are in communication with the steam supply channel P11 for the steam for the cooking. The cooking steam inlet 201 is used to receive the steam from the steam generating device 40, and the cooking steam outlet 202 is used to communicate the steam supply channel P11 for the steam for the cooking with the cooking cavity. The position of the cooking steam inlet 201 corresponds to the outlet of the water container 41, specifically above the water container 41. Figure 4 The steam flow path is schematically indicated by arrows. Specifically, the steam generated by the water in the water container 41 after being heated enters the steam supply channel P11 for the steam for the cooking via the cooking steam inlet 201, flows along the steam supply channel P11 for the steam for the cooking, and enters the cooking cavity via the cooking steam outlet 202. The channel bottom shell is provided with a steam passing portion 67 near the front end portion 56 thereof, and the cooking steam outlet is provided in the steam passing portion 67. The cooking steam inlet is provided in the cooking steam docking cover 30.

[0100] The steam channel component 200 is further provided with a cooking steam inlet 203 and a cooking steam outlet 204 which are in communication with the steam exhaust channel P12 for the steam for cooking. The cooking steam inlet 203 is used to communicate the steam exhaust channel P12 for the steam for cooking with the cooking cavity, and the cooking steam outlet 204 is used to exhaust the steam in the steam exhaust channel P12 for the steam for cooking.

[0101] Referring to Figure 3 , Figure 4 and Figure 6The steam passage assembly 50 comprises a passage bottom shell 51 and a tubular member 52. The tubular member 52 forms the complementary cooking steam supply passage P11. The passage bottom shell 51 is provided with a steam inlet column 54 extending upwardly, which is hollow for steam to pass through. The steam inlet column 54 is in communication with the complementary cooking steam outlet so as to be in communication with the cooking cavity. The steam inlet column 54 is provided at the steam passing portion 67. The tubular member 52 is used to deliver steam from the steam generating device 40. The tubular member 52 is made of a high-temperature resistant elastic material, such as high-temperature resistant silicone or any suitable elastic material. The tubular member 52 is connected with the steam inlet column 54, whereby the tubular member 52 can be mounted on the passage bottom shell 51. The tubular member 52 is in communication with the cooking cavity via the steam inlet column 54, so as to introduce high-temperature steam into the cooking cavity.

[0102] The steam passage assembly 50 further comprises a passage top plate 53. The passage top plate 53 is located on the upper side of the passage bottom shell 51 and can be covered to the passage bottom shell 51, so that the cooking steam discharge passage P12 can be formed between the passage bottom shell 51 and the passage top plate 53. The outer periphery profiles of the passage bottom shell 51 and the passage top plate 53 correspond in shape, and the outer periphery profiles of the passage bottom shell 51 and the passage top plate 53 are shown to be generally triangular in shape.

[0103] In some examples, such as the example shown, the complementary cooking steam supply passage P11 is located on one side of the cooking steam discharge passage P12. The tubular member 52 and the components constituting the cooking steam discharge passage P12 are respectively provided in different regions of the passage bottom shell 51, so that the components constituting the cooking steam discharge passage P12 have a small size, and are independently assembled to the passage bottom shell 51 without affecting each other during the assembly process.

[0104] The tubular member 52 is detachably connected with the steam inlet column 54, so as to be detached from the steam passage assembly 50. The tubular member 52 can be individually detachable, so as to be easily replaced and cleaned.

[0105] In order to communicate the tubular member 52 with the water container 41, an upwardly extending steam receiving column 32 is further provided, which is hollow for steam to pass through. The steam receiving column 32 can be connected with the tubular member 52. In the example shown, the steam receiving column 32 is provided on the complementary cooking steam docking cover 30 and is in communication with the complementary cooking steam inlet. Alternatively, the steam receiving column 32 is provided on the passage bottom shell 51. The tubular member 52 is in communication with the water container 41 via the steam receiving column 32, so that high-temperature steam from the water container 41 enters the tubular member 52. The passage bottom shell 51 is provided with a through hole 55 (see Figure 6 The complementary cooking steam docking cover 30 is located on the lower side of the passage bottom shell 51 and abuts against the passage bottom shell 51. The steam receiving column 32 extends upwardly via the through hole 55 and is limited in the through hole 55. The complementary cooking steam docking cover 30 can limit the movement of the passage bottom shell 51 in the horizontal direction at the steam receiving column 32, avoiding the relative position of the complementary cooking steam docking cover 30 and the passage bottom shell 51 from changing, which improves the stability of the structure.

[0106] The steam inlet column 54 is located at the front end 56 of the passage bottom shell 51 in the longitudinal direction. In design, the steam passage assembly 50 can better utilize the space in the longitudinal direction to arrange the steam passage with a longer extension path, so as to miniaturize the steam passage assembly 50 in the longitudinal direction, thereby reducing the size of the part of the steam passage assembly 50 on the cover plate 14 and reducing the area ratio. The steam receiving column 32 and the cooking steam docking cover 30 are located at the side end 57 of the passage bottom shell 51 in the transverse direction. In this way, the position of the steam receiving column 32 can be corresponded to the water container 41 in the pot body 2 up and down, and the steam enters the steam receiving column 32 from the bottom to the top, so that the steam path between the steam receiving column 32 and the steam generating device 40 is short and straight.

[0107] As described above, the cooking steam docking cover 30 is arranged on the seat support part 21; if necessary and / or desired, the cooking steam docking cover 30 can be arranged on the passage bottom shell 51.

[0108] The steam inlet column 54 and the steam receiving column 32 are respectively provided with a connecting column 71 extending in the horizontal direction. The connecting column 71 is hollow to pass steam. The end of the tubular piece 52 can be sleeved on the connecting column 71 with interference fit. The connecting mode of the tubular piece 52 is simple, that is, the tubular piece 52 is directly sleeved on the connecting column 71, and the interference fit avoids air leakage and ensures the sealing of the connection. In order to facilitate the installation of the tubular piece 52, the mouth of the connecting column 71 is configured to have a round corner or an inclined corner. Specifically, the front end corner of the mouth is chamfered to form a round corner or an inclined corner. In this way, the end of the tubular piece 52 is easily sleeved into the connecting column 71, which can improve the assembly efficiency.

[0109] Optionally, as shown in Figure 5 the connecting column 71 can be provided with a protruding rib 73 with a guide surface 72, for example, the protruding rib 73 is arranged at a distance of 4-6 mm from the mouth of the connecting column 71, and the guide surface 72 gradually extends radially outward from the mouth along the axial direction of the connecting column 71. The protruding rib 73 is arranged around the outer periphery of the connecting column 71, and the end of the tubular piece 52 can be sleeved on the connecting column 71 through the protruding rib 73. The maximum outer diameter of the protruding rib is greater than the inner diameter of the tubular piece 52, so as to interfere fit. By designing the protruding rib 73, the end of the tubular piece 52 can be gradually expanded along the guide surface 72, and the end of the tubular piece 52 is easily sleeved into the connecting column 71, which can improve the assembly efficiency. In addition, the whole circle of the protruding rib 73 can avoid air leakage and ensure the sealing of the connection.

[0110] Optionally, the protruding rib 73 can not be arranged, and the inner diameter of the tubular piece 52 is arranged to be smaller than the outer diameter of the connecting column 71, so as to interfere fit.

[0111] In some examples, the cover plate 14 has a connecting portion 23 with a supplementary steam opening 22. The supplementary steam opening 22 can communicate with the steam inlet column 54, allowing steam in the supplementary steam supply channel P11 to be delivered to the cooking chamber. In this design, the communication between the cooking chamber and the supplementary steam supply channel P11 is achieved through the supplementary steam opening 22 and the steam inlet column 54. The steam channel assembly 50 also includes a steam passage seal 63, which can be disposed between the steam inlet column 54 and the connecting portion 23 of the cover plate 14. Thus, the seal between the cover plate 14 and the steam inlet column 54 is achieved through the steam passage seal 63, preventing steam from entering the interior of the cover body 3 and preventing damage to the electrical components inside the cover body 3. Optionally, the steam passage seal 63 is fitted onto the bottom of the steam inlet column 54.

[0112] like Figure 6 As shown, the steam passage assembly 50 also includes a cooking steam passage seal 59, which is disposed between the passage top plate 53 and the passage bottom shell 51 to form a seal. In some examples, the cooking steam passage seal 59 is disposed on the passage bottom shell 51 and abuts against the passage top plate 53. In this embodiment, the passage bottom shell 51 is provided with a pressure plate 60 for fixing the cooking steam passage seal 59. The pressure plate 60 forms the bottom wall of the cooking steam discharge passage P12; thereby, the pressure plate 60, the cooking steam passage seal 59, and the passage top plate 53 enclose the cooking steam discharge passage P12. In some alternative examples, one of the passage top plate 53 and the passage bottom shell 51 is provided with a groove, and the outer periphery of the passage top plate 53 and the other of the passage bottom shell 51 are provided with a passage wall, with the cooking steam passage seal 59 located in the groove and abutting against the passage wall.

[0113] See Figure 6 The cover plate 14 is provided with a cooking steam opening 24, through which steam in the cooking chamber can enter the cooking steam discharge channel P12 via the cooking steam opening 24 and the cooking steam inlet 61. Optionally, the steam channel assembly 50 also includes a steam valve 62, which passes through the cooking steam opening 24 and the cooking steam inlet 61 to connect the cooking steam discharge channel P12 with the cooking chamber. By providing the steam valve 62, overflow of rice water can be prevented, the steam pressure in the cooking chamber can be regulated, and the steam discharge can be controlled. The height of the steam valve 62 may be higher than the height of the channel top plate 53, so the channel top plate 53 may be provided with a protrusion 64, the inner cavity of which accommodates part of the steam valve 62.

[0114] The channel top plate 53 is provided with a cooking steam outlet 58 for discharging steam in the cooking steam discharge channel P12. The lid body 8 is provided with the steam discharge channel as described above. The cooking steam outlet 58 is positioned corresponding to the steam discharge channel of the lid body 8. Steam in the cooking cavity enters the cooking steam discharge channel P12 via the cooking steam opening 24, flows along the cooking steam discharge channel P12, and flows to the steam discharge channel via the cooking steam outlet 58, and then is discharged to the ambient environment.

[0115] The cover plate 14 needs to be made of food-grade material as it forms the top wall of the cooking cavity. The channel bottom shell 51, the tubular member 52 and the channel top plate 53 are all separate components and can be made of different materials from the cover plate 14. The components for enclosing the steam channels, such as the channel bottom shell 51, the tubular member 52, the channel top plate 53, and the pressing plate 60 are also made of food-grade material. In this way, the top wall of the steam channel can be formed without the lid body 8, so that the lid body 8 does not need to be made of food-grade material, thereby saving material cost.

[0116] The steam channel assembly 50 is at least partially mounted on the detachable lid assembly 13, so that the steam channel assembly 50 is at least partially detached from the lid body 3 together with the detachable lid assembly 13, and the two steam channels on the steam channel assembly 50 can be cleaned. For the illustrated example, at least the channel bottom shell 51 is mounted on the detachable lid assembly 13, so that at least the channel bottom shell 51 is detached from the lid body 3 together with the detachable lid assembly 13. Specifically, the channel bottom shell 51 is connected with the detachable lid assembly 13 to be detached from or mounted to the lid body 3 together with the detachable lid assembly 13. Thus, at least the channel bottom shell 51 can be detached from the lid body 3 for cleaning the two steam channels. The channel top plate 53 can be separated from the channel bottom shell 51 to expose the inside of the steam channel for better cleaning of the inside of the steam channel. The channel bottom shell 51 can be connected to the seat support portion 21 by channel welding, fasteners such as screws, or any suitable means.

[0117] For the illustrated example, the channel top plate 53 is detachably connected with the channel bottom shell 51 to be detached from or mounted to the lid body 3 together with the channel bottom shell 51. When the steam channels need to be cleaned, the whole of the steam channel assembly 50 and the detachable lid assembly 13 can be detached from the lid body 3, and then the channel top plate 53 can be detached from the channel bottom shell 51. In this way, part of the cooking steam discharge channel P12 on the channel top plate 53 is exposed, and part of the cooking steam discharge channel P12 on the channel bottom shell 51 is also exposed. The detachable lid assembly 13 and the channel bottom shell 51 detached from the lid body 3 can be cleaned by the user with water, and the channel top plate 53 detached from the lid body 3 can be cleaned by the user with water separately. The user can easily clean the steam channels P1, and the cleaning effect is good.

[0118] Alternatively, the channel top plate 53 is connected with the cover body 8. The channel top plate 53 covers the channel bottom shell 51, and the two can be fixedly connected. When the steam channel P1 needs to be cleaned, the channel bottom shell 51 and the detachable cover assembly 13 can be removed from the cover body 3 as a whole. In this way, part of the cooking steam exhaust channel P12 on the channel top plate 53 is exposed, and part of the cooking steam exhaust channel P12 on the channel bottom shell 51 is also exposed. The channel bottom shell 51 and the detachable cover assembly 13 removed from the cover body 3 can be cleaned by the user with water, and the channel top plate 53 remaining in the cover body 3 can be cleaned by the user. In this scheme, the channel top plate 53 is butted with the channel bottom shell 51 on the detachable cover assembly 13 when the detachable cover assembly 13 is installed to the cover body 3, so as to form a closed cooking steam exhaust channel P12.

[0119] In the first embodiment, the cooking steam outlet and the cooking steam inlet are arranged separately on the channel bottom shell in different regions far apart. Alternatively, the cooking steam outlet and the cooking steam inlet are arranged in a small region of the channel bottom shell. For example, the channel bottom shell is provided with an inlet and outlet concentration part, and the cooking steam outlet and the cooking steam inlet are arranged in the inlet and outlet concentration part. The cooking steam outlet and the cooking steam inlet are ingeniously designed to be concentrated in a relatively small region, so that the structure of the assembly is more compact as a whole, the occupied space on the cover body is reduced, and it is possible to provide other devices for improving the cooking effect (for example, an infrared radiation device) on the cover body while providing the steam cooking function. Moreover, the design scheme also makes the size of the whole assembly smaller due to the compact structure, thereby saving materials and reducing costs. Further, the assembly can be integrally removed from the cover body, which is convenient for cleaning after use. The shell-shaped structure further improves the convenience of cleaning.
