The heating assembly 100 of the present embodiment will be described in detail below with reference to fig. 3 to 7.

As shown in fig. 3, the heating assembly 100 may include an infrared heat-generating tube 110 and a sealing member 120. The infrared heating tube 110 serves to radiate infrared rays, which are radiated toward the cooking space. The sealing member 120 is located at one side, specifically, an upper side, of the infrared heating tube 110, and is used to seal the infrared heating tube 110. The sealing member 120 is an elastically deformable member made of a material such as silicone rubber.

As shown in fig. 4, the infrared heating tube 110 has two opposite tube ends 111 for connecting electric wires. As shown in fig. 5, the sealing member 120 can be provided with a mounting groove 121 and a mounting hole 122. The opening of the mounting groove 121 faces the side of the infrared heating tube 110, i.e., upward. The infrared heating tube 110 can be positioned in the mounting groove 121, and particularly, a portion of the infrared heating tube 110 is positioned in the mounting groove 121 to restrict movement of the infrared heating tube 110. The mounting groove 121 may have groove end walls 123 at both ends of the mounting groove 121. The mounting hole 122 is provided to the groove end wall 123 and communicates with the mounting groove 121. The two tube ends 111 of the infrared heating tube 110 are respectively positioned in the corresponding mounting holes 122 to seal the tube ends 111 and restrict the movement of the tube ends 111. The mounting holes 122 are through holes. The tube end 111 can protrude from the mounting hole 122.

In this embodiment, the infrared heating tube 110 can be provided to the sealing member 120 in combination with the sealing member 120, and by means of the sealing member 120, not only both end portions of the infrared heating tube 110 but also a gap between the infrared heating tube 110 and a component located at an upper side thereof can be sealed when the heating assembly 100 is mounted to the cover body 10, and for the illustrated embodiment, the gap between the infrared heating tube 110 and the inner cover 11 is sealed to prevent steam from entering the inside of the cover body 10 to damage the infrared heating tube 110. Since the both end portions and one side of the infrared heat-generating tube 110 are sealed, it is possible to expose the infrared heat-generating tube 110 in the cooking space.

Because the infrared heating tube 110 can be exposed in the cooking space, compared with the existing cover body 10 provided with a light-transmitting plate, the cover body 10 in the scheme does not need to be provided with the light-transmitting plate, thereby reducing the material cost, simplifying the structure of the cooking utensil and improving the production efficiency; and infrared rays can be radiated towards the cooking space directly without obstruction, the heat loss is avoided, and the heating efficiency is higher.

The outer contour of the sealing member 120 at the mounting groove 121 corresponds to the shape of the infrared heating tube 110. For example, for the circular ring-shaped infrared heating tube 110, the outer contour shape of the sealing member 120 at the mounting groove 121 is a circular arc. The surface in the mounting groove 121 is matched with the shape of the infrared heating tube 110. The shape of the mounting hole 122 is adapted to the shape of the pipe end 111. For example, the pipe end 111 has a circular cross-sectional shape, and the mounting hole 122 has a circular hole. The diameter of the tube end 111 is slightly smaller than or equal to the diameter of the mounting hole 122.

The infrared heat generating tube 110 and the sealing member 120 may present substantially similar shapes/contours, which makes the structure of the heating assembly 100 more neat and compact, and the overall size of the heating assembly 100 smaller, thereby facilitating the miniaturization of the cooking appliance, and when the cover body 10 is opened, the arrangement of the inner side of the cover body 10 is observed more beautifully and visually.

The infrared heat-generating tube 110 may be configured in a ring shape. Such as a donut shape, a U-shaped ring, a pear-shaped ring, and the like. The seal 120 may be provided with a hollow bore 124 to form a ring shape. In this embodiment, the seal 120 may be referred to as a seal ring. The hollow hole 124 can reduce the amount of material used to prepare the sealing element 120, and reduce material cost. The hollow hole 124 has a shape corresponding to the shape of the infrared heat generating tube 110. The contour of the sealing member 120 away from the center thereof may correspond to the shape of the infrared heat emitting tube 110. The shape of the mounting groove 121 corresponds to the shape of the infrared heating tube 110. For example, the infrared heating tube 110 has a circular ring shape, the hollow hole 124 has a circular arc-shaped contour, the mounting groove 121 has a circular ring shape, and the contour of the sealing member 120 away from the center thereof has a circular arc shape.

The heating assembly 100 may also include a gland 130. The gland 130 is configured in a plate shape. The pressing cover 130 is located on a side, specifically, a lower side, of the infrared heat generating tube 110 facing away from the side where the sealing member 120 is located. The infrared heat generating tube 110 is provided with a first flange 112. The first flange 112 can be located on the side of the center of the infrared heat generating tube 110, and specifically, the first flange 112 is provided on the surface of the infrared heat generating tube 110 toward the center thereof and extends toward the center of the infrared heat generating tube 110. The gland 130 can abut the first flange 112, and in particular a portion of the peripheral edge of the gland 130 abuts the first flange 112. The pressing cover 130 does not cover the infrared heating tube 110 except for the two tube ends 111. The infrared heating tube 110 may be sandwiched between the pressing cover 130 and the sealing member 120 by the first flange 112, so that the infrared heating tube 110 is stably and reliably fixed; and the structure of the pressing cover 130 is advantageous to expose the infrared heating tube 110.

The peripheral edge of the pressing cover 130 abutting against the first flange 112 corresponds to the shape of the infrared heat generating tube 110. For example, in the annular infrared heating tube 110, the outer contour of the pressing cover 130 at the peripheral edge abutting the first flange 112 is in the shape of a circular arc. The infrared heat-generating tube 110 and the pressing cover 130 may present substantially similar shapes/contours, which makes the structure of the heating assembly 100 more neat and compact, and the overall size of the heating assembly 100 smaller, thereby facilitating the miniaturization of the cooking appliance, and when the cover body 10 is opened, the arrangement of the inner side of the cover body 10 is observed more beautifully and visually.

As shown in fig. 6, the pressing cover 130 has a second surface F2 facing the side where the infrared heat generating tube 110 is located. The second surface F2 is a plane. The cover 130 may be provided with a fixing structure 131 for mounting the heating assembly 100. The fixing structure 131 is disposed on the second surface F2 of the gland 130, specifically, at a portion of the gland 130 corresponding to the hollow hole 124 of the sealing member 120. In the illustrated embodiment, the securing structure 131 is a plurality of screw posts. A plurality of screw posts are arranged at intervals. Referring back to fig. 2, the inner lid 11 may be provided with a downwardly opening recess 16, and the heating assembly 100 may be located within the recess 16. The pressing cover 130 can be coupled with the inner lid 11, and specifically, the inner lid 11 is provided with fixing holes 17 corresponding to the up-down positions of the screw posts. The pressing cover 130 is fixed to the inner lid 11 by screws.

Thus, the pressing cover 130 can be coupled to the cover body 10 by means of the fixing structure 131 on the pressing cover 130, and the sealing member 120 is sandwiched between the pressing cover 130 and the cover body 10, particularly between the pressing cover 130 and the inner cover 11, thereby mounting the entire heating assembly 100 to the cover body 10, and the mounting manner of the heating assembly 100 is simple and the assembly efficiency is high.

The sealing member 120 has a first surface F1 facing the side where the infrared heat generating tube 110 is located, and the first surface F1 may also be referred to as a lower surface of the sealing member 120. The first surface F1 is a plane. The mounting groove 121 can be recessed from the first surface F1, and a portion of the groove end wall 123 above the mounting hole 122 protrudes from the first surface F1. The gland 130 can abut the first surface F1. The pressing cover 130 abuts against the sealing member 120, so that sealing can be formed between the pressing cover 130 and the cover body 10, specifically between the pressing cover 130 and the inner cover 11, and steam is prevented from entering the cover body 10 through the space between the pressing cover 130 and the cover body 10, and the sealing effect is good.

The gland 130 may be provided with two projections 132 having indentations 133. The protruding portion 132 can protrude from the peripheral edge of the cover 130, which abuts the first flange 112, in a direction away from the center of the cover 130. The projection 132 corresponds up and down with the position of the pipe end 111. The opening of the pressure groove 133 faces the side of the infrared heat-generating tube 110. The tube end 111 can be located within the indent 133. Further, the portion of the groove end wall 123 protruding from the first surface F1 is located in the press groove 133, so that the pipe end 111 located in the mounting hole 122 is also located in the press groove 133. The groove end wall 123 can abut a surface within the indent 133. The surface of the pressure groove 133 is adapted to the shape of the groove end wall 123, for example, the surface of the groove end wall 123 abutting against the pressure groove 133 is an arc surface, and the cross-sectional shape of the surface of the pressure groove 133 is an arc.

Thereby, the tube end 111 of the infrared heating tube 110 can be sandwiched between the pressing cover 130 and the sealing member 120 by the projection 132, and the movement of the infrared heating tube 110 is further restricted; by means of the pressing groove 133, not only can a more effective seal be formed between the tube end 111 and the pressing cover 130, but also the movement of the tube end 111 can be restricted, thereby making the infrared heating tube 110 more stably and reliably mounted.

The infrared heat-generating tube 110 may also be provided with a second flange 113. The second flange 113 is located on a side of the infrared heat generating tube 110 away from the center thereof, and specifically, the second flange 113 is provided on a surface of the infrared heat generating tube 110 facing away from the center thereof and extends away from the center of the infrared heat generating tube 110. The projection 132 can abut the second flange 113. By means of the second flange 113, the pipe end 111 of the infrared heating pipe 110 can be better clamped between the gland 130 and the sealing member 120, and the movement of the infrared heating pipe 110 can be better limited, so that the infrared heating pipe 110 can be installed more stably and reliably.

The second flange 113 may be located within the mounting groove 121. Specifically, a step 125 may be provided in the mounting groove 121. The step 125 may be located at both sides of the center line of the mounting groove 121. The first and second flanges 112, 113 may each abut a corresponding step 125. Accordingly, the infrared heating tube 110 can be positioned in the mounting groove 121 more stably and reliably without rattling, and the pressing cover 130 can be easily brought into contact with the sealing member 120.

The gland 130 may be provided with a boss 134. The boss 134 is disposed at a peripheral edge of the pressing cover 130 and protrudes from the second surface F2 of the pressing cover 130 facing the infrared heating tube 110. The boss 134 can abut the first flange 112 and the second surface F2 of the gland 130 can abut the first surface F1 of the seal 120. By providing the boss 134, the thickness of the gland 130 can be reduced, thereby reducing the amount of material used to prepare the gland 130 and reducing material costs. The boss 134 extends continuously along the periphery of the gland 130 but is broken at the port of the gland 133.

For the illustrated embodiment, the first flange 112 can extend between the two pipe ends 111, forming an annular flange. A second flange 113 can also extend between the two pipe ends 111, forming an annular flange. In an embodiment not shown, the first flange 112 may be provided in plurality at intervals, and the second flange 113 may be provided only at the two pipe ends 111.

The two tube ends 111 are spaced apart and a portion of the steam channel structure 14 is located between the two tube ends 111. Thus, to avoid the steam channel structure 14, the seal 120 can be provided with a seal gap 126, the seal gap 126 being located between the two groove end walls 123. And the gland 130 may be provided with a gland notch 135, the gland notch 135 being located between the two projections 132. The seal notches 126 correspond in position to the gland notches 135. A portion of the vapor passage structure 14 is located within the seal gap 126 and the gland gap 135.

By providing the gap for avoiding the steam channel structure 14 on the sealing member 120 and the pressing cover 130, the center of the heating assembly 100 can be closer to the steam channel structure 14, so that the structure on the lid body 10 is more compact, which is beneficial to the miniaturization of the cooking appliance. And the overall size of the heating assembly 100 can be designed independently of the steam channel structure 14, so that the overall size of the heating assembly 100 can be reduced, the material cost and the manufacturing cost can be reduced, and further the miniaturization of the cooking appliance can be facilitated.
