And the lower end of the steam outlet seal 160 may be provided with a flange 161 extending away from the center thereof. The lower surface of the snap wall 126 is located above the flange 161 and can abut to the flange 161, i.e. the lower step 127 abuts to the flange 161. Thereby, the movement of the steam outlet seal 160 in the vertical direction with respect to the steam channel wall 125 may be restricted, so that the steam outlet seal 160 may be securely and reliably sleeved on the steam channel wall 125, and is not easily separated, thereby facilitating the assembly of the steam channel wall 125 with the steam outlet seal 160.

The snap-in wall 126 is also provided with an upwardly facing upper step 128. The upper step 128 is recessed from the outside of the steam channel wall 125. The upper end of the steam outlet seal 160 may be provided with a downwardly extending stopper wall 162. The retaining wall 162 is located above the upper step 128 and abuts the upper step 128. A sleeve inlet is formed between the limiting wall 162 and the flange 161. Thereby, the movement of the steam outlet seal 160 in the horizontal direction with respect to the steam channel wall 125 may be restricted, such that the steam outlet seal 160 is provided to the steam channel wall 125 in a nested manner.

In the illustrated embodiment, the cover 100 may further include a steam valve 180. The steam valve 180 is located above the face cover 110 and can be disposed on the face cover 110. Specifically, the face cap 110 may be provided with a face cap recess 115, and the steam valve 180 is disposed within the face cap recess 115. The steam outlet 111 may be provided at the bottom wall of the face cover groove 115. Further, the steam channel wall 125 abuts against the lower surface of the face cover 110 at the face cover groove 115. The positioning wall 112 and the sealing boss 113 are located at positions opposite to the position of the face cover groove 115.

The steam valve 180 may be provided with an air outlet 181 and an air inlet 182 with an air inlet 183. The air outlet 181 communicates with the air inlet hole 183 so that the steam passes therethrough. The openings of the intake holes 183 are, for example, downward and circular in shape. The center line of the air intake hole 183 may be collinear with the center line of the steam outlet 111. The air intake 182 is located in the steam outlet 111 and passes out of the steam outlet 111. The vapor outlet seal 160 can abut the air intake portion 182. By providing the steam outlet sealing member 160, one sealing member can be used to form double sealing, i.e., the gap between the sealing surface cover 110 and the steam channel wall 125, and the gap between the steam channel wall 125 and the steam valve 180 can be sealed, thereby reducing the number of components in the lid body 100, simplifying the structure inside the lid body 100, optimizing the size of the lid body 100, and facilitating the miniaturization of the cooking appliance.

In an embodiment not shown, the steam valve 180 may not be provided, and the steam outlet 111 serves as the air outlet 181.

The air inlet 182 may be located within a through-hole of the vapor outlet seal 160. The aperture wall of the steam outlet seal 160 is provided with an annular sealing projection 163. The sealing protrusion 163 can protrude toward the center of the vapor outlet seal 160 and abut the air inlet 182. The sealing protrusion 163 may be compressed by the pressing action of the air inlet portion 182 to be more deformed. This improves the deformability of the steam outlet seal 160, and improves the sealing between the steam outlet seal 160 and the air inlet 182.

Referring back to fig. 3, the cover 100 may further include a temperature sensing element 190 having a temperature sensing head 191 and an element seal 192. The temperature sensing element 190 is used to sense the temperature of the steam in the steam channel. The steam channel wall 125 may be provided with a mounting hole 129 (fig. 5), and the temperature sensing element 190 is disposed within the mounting hole 129. The temperature sensing head 191 is located inside the steam channel wall 125, and the element seal 192 is disposed between the wall of the mounting hole 129 and the temperature sensing element 190. The element sealing member 192 has a through hole and is capable of being sleeved on the temperature sensing element 190. Thereby, the temperature of the steam in the steam passage can be sensed, and the element sealing member 192 can achieve sealing at the temperature sensing element 190, so that the steam or the steam with entrained rice water can be further prevented from entering the inside of the cover body 100.

As shown in fig. 3 and 8, in the present embodiment, the steam inlet seal 170 can be non-detachably connected to the inlet of the steam channel enclosed by the steam channel wall 125. The lower portion of the steam inlet seal 170 abuts the upper surface of the removable cover 130. Steam inlet seal 170 and liner 120 may be constructed as a single component by injection molding or overmolding. For example, steam inlet seal 170 may be optionally injected over formed liner 120, and liner 120 may optionally be injected over formed steam inlet seal 170. With this embodiment, a fixing structure for assembly is not required, production and manufacturing are facilitated, and the coupling strength is reliable, and it is also possible to simplify the assembly process of the cover body 100 and improve the assembly efficiency.

The steam inlet seal 170 includes a seal body 172 and a deformation 173 connected to the seal body 172. The seal body 172 may be integrally connected to the liner 120 and the deformation 173 may abut the removable cover 130. The deformation 173 may be configured as a lip. The steam inlet seal 170 may be provided with a protrusion 174. The projection 174 projects in a direction away from a centerline of the steam inlet seal 170. further, the projection 174 is connected to the seal body 172 and projects from the seal body 172 in a direction away from the centerline of the steam inlet seal 170. The projection 174 can be buried in the steam passage wall 125. That is, the remaining portion of the protrusion 174 except for the portion connected to the seal body 172 is provided in the steam passage wall 125. This improves the strength of the connection between the steam inlet seal 170 and the liner 120, and allows the steam inlet seal 170 to be more firmly and reliably connected integrally with the liner 120 and not to be easily detached.

Seal body 172 is located within the area formed by steam channel wall 125. The periphery of the seal body 172 may be integrally connected with the steam passage wall 125. The seal body 172 is integrally connected to the liner 120 at a portion above the lower surface of the liner 120. In the illustrated embodiment, the seal body 172 is a straight cylindrical shaped annular wall. The deformation portion 173 is bent with respect to the seal body 172. The seal body 172 is substantially entirely over the lower surface of the liner 120. Seal body 172 is substantially integrally connected to liner 120. Thereby, a portion where the steam inlet seal 170 and the liner 120 are integrally connected to each other may be increased, further improving the connection strength between the steam inlet seal 170 and the liner 120.

The dimension H of the portion of the seal body 172 that is integrally connected with the steam channel wall 125 in a direction parallel to the centerline of the steam inlet seal 170 is H ≧ 2mm, for example dimension H can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, and so forth. During production, for example, steam inlet seal 170 is injection molded onto molded liner 120, the surface of liner 120 for integral connection with steam inlet seal 170 having an area S ≧ 2mm ² . For example, the liner 120 is injection molded on the molded steam inlet seal 170, and the surface of the steam inlet seal 170 for integral connection with the liner 120 has an area S1 ≧ 2mm ² . For example, dimensions S and S1 may be 60mm ² 、65mm ² 、70mm ² 、75mm ² 、80mm ² 、85mm ² And the like.

The inner wall surface of the seal body 172 may be coplanar with the inner wall surface of the steam passage wall 125. Therefore, the steam inlet sealing element 170 and the lining 120 can be conveniently molded in a molding mode, the mold is simple in structure, and the mold is convenient to produce and manufacture, so that the production and manufacturing cost is reduced.
