The cover body 100 may further include an infrared heating element 131 for radiating infrared rays to the cooking space. The infrared heating element 131 is disposed on the cover main body, particularly, the inner liner 110. The food can be effectively heated by utilizing infrared rays, so that the food is uniformly heated, and the aroma of the food is excited. The illustrated embodiment shows an example in which infrared heating element 131 is a carbon-containing element that is enclosed in a glass tube 132 that is configured as an infrared electrothermal tube 130. Alternatively, the infrared heating element 131 may be any suitable infrared radiating element such as an electric heating film that can be directly energized.

The cover 100 may also include an infrared transmissive element 140. The infrared transmitting element 140 can be disposed at a side, e.g., a lower side, of the infrared heating element 131 facing the cooking space. Removable cover 120 is positioned over infrared transmissive element 140. Therefore, by means of the infrared transmission element 140, the infrared heating element 131 can be isolated, so as to prevent water, liquid, steam, etc. from entering the infrared heating element 131 to affect the infrared heating element 131, and prevent the user from directly touching the infrared heating element 131 to cause scalding or electric shock when the cover body 100 is opened.

The infrared transmitting member 140 is provided with a light transmitting region corresponding to the position of the infrared heating element 131 so that the infrared rays generated from the infrared heating element 131 are easily radiated downward through the infrared transmitting member 140. One example is where the infrared-transmissive element 140 is integrally constructed to be light-transmissive, for example, the illustrated embodiment shows the infrared-transmissive element 140 as a glass piece; in this embodiment, the light-transmitting region is a region through which infrared rays pass on the infrared-transmitting element 140. Another example is that the infrared transmitting element 140 may include a light-transmitting portion having a shape corresponding to that of the infrared heat generating element 131 and a support portion for supporting the light-transmitting portion; in this embodiment, the light-transmitting region is a region defined by a light-transmitting portion, and the infrared transmitting element 140 is partially configured to transmit light.

As shown in fig. 3, the liner 110 is provided with a liner opening 111. The infrared heating element 131 and the infrared transmitting element 140 are both mounted in the liner opening 111. Removable cover 120 is positioned below infrared-transmissive element 140. Removable cover 120 can be partially provided with a light transmissive opening 121. The light transmission opening 121 corresponds to the position of the infrared heating element 131. In other words, the light-transmitting opening 121 is located directly below the infrared heat generating element 131. Infrared rays generated from the infrared heating element 131 can be radiated toward the inner pot through the light transmitting opening 121. The cover 100 may further include a sealing member 150 having a ring shape. The sealing member 150 can be provided at the light-transmitting opening 121 to seal at least a gap between the infrared transmitting element 140 and the detachable cover 120. The seal 150 is integrally made of an elastic material.

The cover body 100 may further include a reflection member 160. The reflection member 160 can be disposed above the infrared heating element 131 to reflect the infrared rays radiated upward from the infrared heating element 131 to the cooking space, whereby the radiation amount of the infrared rays for heating the food can be increased. The infrared heating element 131 can be mounted to the reflector 160. In the illustrated embodiment, the reflector 160 is located above the infrared electrothermal tube 130, and the lower side of the reflector may be provided with one or more tube clamps, and the infrared electrothermal tube 130 is mounted to the reflector 160 through a tube frame.

In this embodiment, both the infrared transmissive element 140 and the reflector 160 may be mounted to the liner 110. Specifically, the liner 110 may be provided with an annular step 112. An outer edge of the infrared transmission element 140 is connected to the stepped portion 112, specifically, to an upper surface of the stepped portion 112 to support the infrared transmission element 140 upward. The cover 100 may further include a fixing member 170. Mount 170 is mounted to liner 110 and positioned over infrared-transmissive element 140. The fixing member 170 can abut against an outer edge of the infrared transmission element 140 to restrict the infrared transmission element 140 from moving in the vertical direction. Accordingly, the inner liner 110 provides an upward supporting force to the infrared transmission element 140, and the fixing member 170 provides a downward pressing force, so that the infrared transmission element 140 can be firmly and reliably fixed to the inner liner 110, the assembly structure is simple, and the assembly process is easy to operate.

The outer edge of the reflecting member 160 and the fixing member 170 are mounted to the inner liner 110 by the same fastener. Specifically, the outer edge of the reflector 160 may be provided with a reflector through-hole 161, and the fixture 170 is provided with a fixture through-hole 171, and a fastener (not shown) such as a screw can pass through the reflector through-hole 161 and the fixture through-hole 171 to mount the reflector 160 and the fixture 170 to the inner liner 110. Specifically, the liner 110 may be provided with liner fixing holes 113, and the fasteners may be screwed into the liner fixing holes 113. With this embodiment, the simultaneous fixing of the reflection member 160 and the fixing member 170 can be achieved, and thus the reflection member 160 and the infrared transmission element 140 can be simultaneously fixed, which reduces the number of assembly parts, simplifies the assembly structure, thereby improving the assembly efficiency and facilitating the miniaturization of the cover body 100.

Referring back to fig. 1, the cover body 100 may be provided with a steam passage structure disposed near the rear end of the cover body 100. Specifically, the cover 100 comprises a steam valve 106, a steam channel wall 107 and a steam channel seal 108. The steam valve 106 is provided on the lid 101. Steam channel wall 107 extends in a vertical direction and is located between face cover 101 and liner 110. Steam channel seal 108 is disposed in liner 110. The steam channel wall 107 encloses a steam channel extending in a vertical direction, and the steam channel seal 108 is provided with a steam channel therethrough. The steam channel of the steam channel seal 108 communicates with the steam valve 106 via a steam channel enclosed by the steam channel wall 107, in order to discharge the steam to the environment. The steam channel wall 107 may be provided with a temperature sensing element 109 for sensing the temperature of the steam in the steam channel.

The arrangement and structure of the seal 150 and the structure of the step portion 112 are specifically described below with reference to fig. 3 to 6.

As shown in fig. 3 and 4, seal 150 may be located above removable cover 120. The seal 150 has an upper portion and a lower portion. An upper portion of the seal 150 is interposed between the liner opening 111 and the infrared transmission element 140, and more specifically, between an edge of the liner opening 111 and the infrared transmission element 140, to seal a gap between the liner 110 and the infrared transmission element 140. The lower portion of sealing member 150 can abut against removable cover 120, specifically against the edge of light-transmitting opening 121, to seal the gap between removable cover 120 and infrared-transmitting element 140.

In this embodiment, a single seal can be used to seal both the gap between inner liner 110 and infrared transmissive element 140 and the gap between removable cover 120 and infrared transmissive element 140 from vapor entering cover 100. This can reduce the number of components in the cover body 100 and simplify the assembly process. Thus, the sealing member 150 according to the present embodiment is easy to assemble and operate, has high assembly efficiency, and can reduce the material cost and the manufacturing cost of the lid body 100.

An annular step 112 surrounds the liner opening 111. The upper portion of the sealing member 150 is sandwiched between the outer edge of the infrared-transmitting element 140 and the upper surface of the stepped portion 112. The sealing member 150 is mounted to the inner liner 110 by means of the clamping between the stepped portion 112 and the infrared transmission member 140 without additionally providing an auxiliary member for fixing the sealing member 150, which can further reduce the number of components in the cover body 100 and simplify the assembly process.

The sealing member 150 may be provided with a receiving groove 151 (fig. 6), the notch of the receiving groove 151 facing away from the center of the sealing member 150 (fig. 5). The step part 112 can be received in the receiving groove 151. Therefore, the sealing member 150 can be easily provided to the stepped portion 112, and at the time of assembly, it is advantageous to hold the sealing member 150 at the assembly position for subsequent placement of the infrared transmission element 140 thereon. In the illustrated embodiment, the step part 112 may be sandwiched between the top and bottom surfaces of the receiving groove 151. Specifically, the top and bottom surfaces of the receiving groove 151 may thus mount the sealing member 150 to the liner 110, so that the sealing member 150 is securely and reliably fixed without being released from the step portion 112. When assembled, the seal 150 is placed on the stepped portion 112, and the seal 150 can be held in the assembled position without the aid of an external force, which facilitates the subsequent placement of the infrared-transmitting element 140. In an embodiment not shown, the step 112 abuts a top surface of the receiving groove 151, and a bottom surface of the receiving groove 151 may be a slope. This allows the portion of the sealing member 150 below the receiving groove 151 to be designed to have a deformation capability, so that the sealing effect of the sealing member 150 can be improved.

As shown in fig. 6, the upper portion of the seal 150 is a seal wall 152 extending in a radial direction on the seal 150. The sealing wall 152 is interposed between the stepped portion 112 and the infrared-transmitting member 140. The lower portion of the seal 150 is the lower edge of the seal 150. The sealing wall 152 can provide a flat support surface to facilitate a snug fit with the infrared-transmissive element 140, prevent gaps or relative movement therebetween, and maintain the infrared-transmissive element 140 mounted horizontally. The lower edge of the sealing member 150 can be deformed for sealing.

The sealing member 150 may further include a first connection wall 153, a second connection wall 154 connecting the sealing wall 152 and the first connection wall 153, and a deformation wall 155 connected to the first connection wall 153. The second connection wall 154 may extend in the axial direction of the seal 150. The sealing wall 152, the second connection wall 154, and the first connection wall 153 form the receiving groove 151. It is shown that the first connecting wall 153 may extend in a radial direction of the seal 150. In an embodiment not shown, the first connection wall 153 may be inclined with respect to a radial direction of the seal 150. The deforming wall 155 is inclined with respect to the first connecting wall 153 and abuts the detachable cover 120. The deformed wall 155 forms the lower edge of the seal 150. Therefore, the sealing element 150 is simple in structure and convenient to produce and manufacture; and deformable wall 155 has a better ability to deform to provide a better seal between infrared-transmissive element 140 and removable cover 120.

The thickness of the first connecting wall 153 is t1, and the thickness of the deforming wall 155 is t 2. The distance between the lower surface of step 112 and the upper surface of removable cover 120 is d. Wherein t1+ t2 is less than or equal to d.

In an embodiment not shown, the upper portion of the seal 150 forms a seal groove portion in which the outer edge of the infrared transmission element 140 is located. The notch of the seal groove portion faces the center of the seal. Therefore, on one hand, the infrared transmission element 140 can be protected by buffering, and the infrared transmission element 140 made of glass is prevented from being damaged due to the fact that the infrared transmission element 140 is shaken or vibrated and the like to impact the lining 110, on the other hand, the sealing area between the sealing lining 110 and the infrared transmission element 140 can be increased, and the sealing effect of the cover body 100 is improved.

The surface of the seal 150 abutting the infrared-transmissive element 140 may be provided with a protrusion 156. The projection 156 extends in the circumferential direction of the seal 150. As shown in fig. 5, the projection 156 is annular. The projections 156 are spaced apart in the radial direction of the seal 150, and for example, two annular projections 156 may be spaced apart. By providing the protrusion 156, the deformation capability of the sealing member 150 can be increased, and the sealing effect between the infrared-transmitting member 140 and the inner liner 110 can be improved.

Further, referring back to fig. 2, the center of the seal 150 is collinear with the center of the light-transmissive opening 121. The distance between the seal 150 and the center of the seal 150 is L1; the distance between the edge of the light-transmitting opening 121 and the center of the light-transmitting opening 121 is L2. Wherein L1< L2.

As shown in fig. 3, the cover 100 may include at least one fixing member 170. At least one fastener 170 can be mounted to liner 110. A plurality of fasteners 170 are shown.

The first-step portion 114 is closer to the center of the liner opening 111 than the second-step portion 115. The infrared transmitting member 140 abuts to the primary stepped portion 114. Secondary step portion 115 is provided with a recessed portion 116 recessed away from the center of liner opening 111, and a fastener 170 is provided at secondary step portion 115 and partially within recessed portion 116. By providing the recess 116, the movement of the fixing member 170 in the horizontal direction can be restricted, and the fixing member 170 is prevented from shaking to loosen the fastening member, so that the infrared transmission element 140 can be fixed more firmly. Adjacent stepped parts 115 may have a gap therebetween. Therefore, the liner 110 can be provided with a hollow structure at the step portion 112, so as to reduce the material cost and the weight of the cover body 100.

As shown in fig. 4, the fixing member 170 may be configured as an angle-shaped member. To avoid accidental injury, removable cover 120 may be configured with a bead 122 at the edge of light-transmissive opening 121 that is bent upward and extends away from the center of light-transmissive opening 121. For example, the bead 122 may be a curled bead 122 or a straight bead 122. Further, the crimp 122 may be a rolled edge or a crimped edge. From this, when lid 100 was opened, can avoid the user to be touched the marginal and by the fish tail of printing opacity opening 121 because of bumping, improved the safety in utilization of lid 100, user experience feels better.
