Referring to fig. 1 to 3, a lid for a steam cooking appliance according to an embodiment of the present invention includes a glass outer lid 110, a glass inner lid 120, an outer connecting member 140, and an inner connecting member 130, wherein the glass outer lid 110 and the glass inner lid 120 are stacked and fixed by the outer connecting member 140 and the inner connecting member 130, and the outer connecting member 140 and the inner connecting member 130 are connected to form an air inlet passage 160 for steam to flow through. The pot cover 100 described in this embodiment is detachably covered on the pot body 200 and forms a cooking cavity, the pot body 200 includes a housing 210 and an inner container 220 disposed in the housing 210, a container opening of the inner container 220 is lower than an upper end surface of the housing 210, when the pot cover 100 covers the pot body 200, an edge of the outer glass cover 110 is pressed on the upper end surface of the housing 210, an edge of the inner glass cover 120 is pressed on the container opening of the inner container 220, the inner glass cover 120 is not exposed, and the beauty and heat preservation are enhanced.

Compare the design of the pot cover window on the ordinary electric rice cooker among the prior art, this embodiment replaces original plastic enclosing cover and metal inner cup into glass enclosing cover 110 and glass inner cup 120 for the visible area greatly increased of pot cover 100 reaches the whole visual effect in week of pot cover 100, and correspondingly, the user can observe the culinary art state of more food in the culinary art space through pot cover 100, promotes the visual experience of user's culinary art. Moreover, the glass outer cover 110 makes the pot cover 100 have a more fashionable and novel appearance, and has better heat resistance and cleaning performance compared with the existing plastic outer cover; the heat conduction capability of the glass inner cover 120 is far lower than that of the existing metal inner cover, and the heat dissipated by the heat conduction of the glass inner cover 120 is far smaller than that of the metal inner cover, so that the heat loss in the cooking process can be reduced, and the steam heating efficiency and the heat preservation performance of the pot cover 100 are improved.

In this embodiment, the glass outer cover 110 and the glass inner cover 120 are stacked and clamped and fixed by the outer connecting member 140 and the inner connecting member 130, specifically, referring to fig. 3, one side of the glass outer cover 110 away from the glass inner cover 120 is pressed by the outer connecting member 140, one side of the glass inner cover 120 away from the glass outer cover 110 is pressed by the inner connecting member 130, and the outer connecting member 140 and the inner connecting member 130 are connected to keep the glass outer cover 110 and the glass inner cover 120 fixed. The connection between the outer connecting member 140 and the inner connecting member 130 not only realizes the assembly of the outer glass cover 110 and the inner glass cover 120, but also forms the air inlet passage 160 for the circulation of steam, and the pot cover has a simple assembly structure, requires a small number of accessories, and thus not only can reduce the cost, but also can prevent redundant accessories from blocking the visible area of the pot cover.

In this embodiment, the pot cover 100 further includes a ring-shaped lining cover 300, and the lining cover 300 is clamped and fixed by the outer glass cover 110 and the inner glass cover 120 and encloses the outer glass cover 110 and the inner glass cover 120 to form the thermal insulation interlayer 150. Due to the heat insulation effect provided by the heat insulation interlayer 150, the glass outer cover 110 is not in direct contact with the glass inner cover 120, so that the heat transfer between the glass outer cover 110 and the glass inner cover 120 can be greatly weakened, heat insulation protection is provided for the glass outer cover 110, the glass outer cover 110 still keeps low temperature rise under the condition of long-time cooking, meanwhile, the further loss of heat of the glass inner cover 120 can be effectively reduced, and the overall heat insulation effect of the pot cover is improved; since the thermal insulating interlayer 150 separates the glass outer cover 110 from the glass inner cover 120, the heat stored in the thermal insulating interlayer 150 can weaken the condensation effect on the inner side of the glass inner cover 120 (the side of the glass inner cover 120 facing the pot body) during cooking, and effectively reduce the condensed water condensed on the glass inner cover 120.

In conjunction with fig. 4, in addition to the thermal insulating interlayer 150 described above, the liner cover 300 also functions to protect the glass outer cover 110 and the glass inner cover 120, as exemplified by: the lining cover 300 includes an upper supporting platform 310 and an upper ring rib 320 protruding from the upper supporting platform 310, the upper supporting platform 310 supports the edge of the outer glass cover 110, the upper ring rib 320 surrounds the outer peripheral surface of the outer glass cover 110, and the upper ring rib 320 can prevent the outer peripheral surface of the outer glass cover 110 from being directly impacted by foreign objects, so that the lining cover 300 can better protect the outer glass cover 110. The lining cover 300 further comprises a lower supporting platform 330 and a lower annular rib 340 protruding from the lower supporting platform 330, the lower supporting platform 330 supports the edge of the inner glass cover 120, the lower annular rib 340 surrounds the outer circumferential surface of the inner glass cover 120, and the lower annular rib 340 can prevent the outer circumferential surface of the inner glass cover 120 from being directly impacted by foreign objects, so that the lining cover 300 can better protect the inner glass cover 120.

Referring to fig. 4, in the present embodiment, a first sealing ring 400 is disposed between the upper ring rib 320 and the outer peripheral surface of the outer glass cover 110, and a second sealing ring 500 is disposed between the lower ring rib 340 and the outer peripheral surface of the inner glass cover 120. The arrangement of the first sealing ring 400 and the second sealing ring 500 makes the heat stored in the heat insulation interlayer 150 not easily run off, and improves the heat insulation effect of the heat insulation interlayer 150; moreover, the first sealing ring 400 and the second sealing ring 500 are generally elastic, so that when the pot cover 100 is subjected to a side impact, the first sealing ring 400 and the second sealing ring 500 can counteract most of the impact force by deforming, so as to better protect the glass outer cover 110 and the glass inner cover 120. In addition, the second sealing ring 500 is also used for tightly adhering to the opening of the inner container 220 of the pot body 200 when the pot cover 100 covers the pot body 200, so as to enhance the sealing performance between the pot cover 100 and the pot body 200.

The lining cover 300 in this embodiment is generally a plastic component, which has better toughness than glass material, so as to protect the outer glass cover 110 and the inner glass cover 120, but when the lining cover 300 shrinks to a certain extent, the upper ring rib 320 is limited by the outer glass cover 110, but the internal stress generated by the shrinkage of the lining cover 300 does not disappear, and the lining cover 300 is easily cracked due to the long-term maintenance of this state, and the lower ring rib 340 also has the above-mentioned problems. Although a proper gap can be reserved between the upper ring rib 320 and the outer peripheral surface of the glass outer cover 110 to solve the above problem, the appearance of the pot cover is damaged, dirt is easily stored in the gap, and the cleaning difficulty is increased.

In this embodiment, due to the elastic effect of the first sealing ring 400, when the material shrinkage of the liner cap 300 causes the diameter of the upper ring rib 320 to decrease, the first sealing ring 400 plays a role in buffering, so as to prevent the crack of the upper ring rib 320 and even the liner cap 300 caused by the direct extrusion of the outer peripheral surface of the glass outer cap 110 on the inner side of the upper ring rib 320, and it is not necessary to reserve an excessively large gap between the upper ring rib 320 and the outer peripheral surface of the glass outer cap 110 in order to prevent the crack of the liner cap 300, thereby damaging the appearance of the pot cover. The same principle is that: due to the elastic action of the second seal ring 500, when the diameter of the lower ring rib 340 is reduced due to the contraction of the material of the lining cover 300, the second seal ring 500 plays a role in buffering, the lower ring rib 340 and even the lining cover 300 are prevented from cracking due to the fact that the inner side of the lower ring rib 340 directly extrudes the outer peripheral surface of the glass inner cover 120, and an overlarge gap does not need to be reserved between the lower ring rib 340 and the outer peripheral surface of the glass inner cover 120 in order to prevent the lining cover 300 from cracking, so that the appearance shape of the pot cover is damaged.

Referring to fig. 5, in an embodiment of the present invention, based on the above embodiment: similarly, in order to solve the problem of cracking caused by shrinkage of the lining cap 300, in this embodiment, a gap is formed between the upper ring rib 320 and the outer peripheral surface of the outer glass cover 110, and a plurality of support ribs 321 are circumferentially arranged on the inner side of the upper ring rib 320. More specifically, during the assembly process of the pot cover, a proper amount of gap is reserved between the upper ring rib 320 and the outer peripheral surface of the outer glass cover 110, a plurality of support ribs 321 are circumferentially arranged on the inner side of the upper ring rib 320, the support ribs 321 extend towards the center direction of the outer glass cover 110, when the material shrinkage of the lining cover 300 causes the diameter of the upper ring rib 320 to decrease, the support ribs 321 are extruded by the outer peripheral surface of the outer glass cover 110 before the upper ring rib 320 to deform, so that the buffering effect is achieved, and the phenomenon that the inner side of the upper ring rib 320 directly extrudes the outer peripheral surface of the outer glass cover 110 to cause the cracking of the upper. The first seal ring can be eliminated or provided only between the upper support platform and the glass outer cover.
