[0054] Example 1
[0055] like Figure 1 , Figure 2 The illustration shows an anti-condensation pot lid disclosed in this embodiment, which mainly includes an outer pot lid 1, an inner pot lid 2, a handle 3, and a connecting assembly. The handle 3 is located on top of the outer pot lid 1. The top view shape of the anti-condensation pot lid can be circular, elliptical, rectangular with rounded corners, square with rounded corners, etc. The inner pot lid 2 has a single-sided concave arc or zigzag surface structure, and its overall size is smaller than that of the outer pot lid 1. The outer pot lid 1 covers the inner pot lid 2, and there is a certain gap between the edge of the inner pot lid 2 and the inner wall of the outer pot lid 1, forming a steam channel 4. Furthermore, there is a space 5 between the inner pot lid 2 and the outer pot lid 1. The concave surface of the inner pot lid 2 faces away from the outer pot lid 1, and the inner pot lid 2 is provided with a vent hole 201. The outer pot lid 1 is provided with an exhaust hole. The outer pot lid 1, the inner pot lid 2, and the handle 3 are connected by the connecting assembly. Among them, the steam channel 4 and the vent 201 are mainly used to connect the lower space and the interlayer space 5 of the inner lid 2, so that there is no obvious temperature difference between the upper and lower surfaces of the inner lid 2, and to prevent the formation of condensation droplets on the lower surface of the inner lid 2.
[0056] refer to Figure 3 When steaming food using a wok with a lid, the heat source heats the wok body, creating a boiling water zone at the bottom. The boiling water produces steam. A portion of the steam will then... Figure 3 The steam flows into the food heating zone (the area below the inner lid 2), heating the food and plates. Another portion of the steam then... Figure 3The steam flows to the interlayer space 5 between the inner lid 2 and the outer lid 1 through the steam passage 4 between the inner lid 2 and the outer lid 1 and the air vent 201 on the inner lid 2, forming a steam condensate area. At this time, a large temperature difference is formed between the high temperature inside the pot and the lower temperature environment outside, and the inside of the pot is full of a large amount of saturated steam, so that a large amount of steam condensate is continuously generated at the contact surface, the inner lower surface of the outer lid 1 and the inner side of the pot body. The steam condensate on the inner side of the pot body flows back to the boiling water area at the bottom of the pot body and does not enter the food and the dish. The steam condensate on the inner side of the outer lid 1 drips onto the top surface of the inner lid 2 and is guided to the edge of the pot body through the arched structure of the inner lid 2 and flows back to the boiling water area at the bottom of the pot body, and also does not enter the food heating area and does not enter the food and the dish. At the same time, since the upper surface of the inner lid 2 and the lower surface of the inner lid 2 above the food heating area are connected through the steam passage 4 between the inner lid 2 and the outer lid 1 and the air vent 201 on the inner lid 2, the temperature of the upper and lower surfaces of the inner lid 2 is also almost the same, that is, there is no temperature difference between the food heating area and the steam condensate area, so that the lower surface of the inner lid 2 does not generate steam condensate, and the food and the dish below the inner lid 2 also do not have condensate dripping into them. In this way, the steam condensate generated in the whole process of cooking food with the wok will flow back to the boiling water area smoothly and will not enter the food and the dish, ensuring that the original moisture content, sugar content, salt content, hardness and other indicators of the cooked food will not change during the cooking process, and the original taste and texture of the food are maintained.
[0057] In this embodiment, the outer lid 1 and the inner lid 2 are made of stainless steel sheet, aluminum alloy sheet, galvanized sheet and other metal materials by stamping. Referring to Figure 1 、 Figure 2 In this embodiment, the handheld piece 3 is a top bead, and the bottom of the top bead is provided with a threaded hole. The center of the outer lid 1 is provided with a first through hole coaxial with the threaded hole, and the center of the inner lid 2 is provided with a second through hole coaxial with the threaded hole. The connecting assembly includes a fastening screw 6 and a first spacing column 7. The nut end of the fastening screw 6 abuts against the bottom of the inner lid 2, the screw rod of the fastening screw 6 passes through the second through hole, the first through hole and the threaded hole in sequence, and the first spacing column 7 is sleeved on the fastening screw 6 and located between the outer lid 1 and the inner lid 2, for controlling the distance between the inner lid 2 and the outer lid 1 to be between 0.5mm and 80mm. Since the outer lid 1 and the inner lid 2 are made of metal materials, a flat washer 8 and a spring washer 9 are preferably sleeved on the fastening screw 6, so that the spring washer 9 and the flat washer 8 are located between the nut end of the fastening screw 6 and the inner lid 2, and the spring washer 9 is located between the nut end of the fastening screw 6 and the flat washer 8. The first spacing column 7 can be directly made of a metal column or a rubber column.
[0058] In the embodiment, the number of the vent holes 201 can be set to be multiple, and each of the vent holes 201 surrounds the second through hole. Preferably, the outer lid 1 is provided with a skirt or a protrusion outwardly turned at the position corresponding to the vent hole 201 to prevent the condensed water from falling through the vent hole 201.
[0059] Further preferably, the inner lid 2 is provided with a planar structure at the region close to the center, and the second through hole and the vent hole 201 are arranged on the planar structure, so as to facilitate the installation of the fastening screw 6 and to avoid the condensed water flowing through the vent hole 201 as much as possible.
[0060] It is worth noting that in the specific application, the outer lid 1 and the inner lid 2 can also be made of glass or plastic. When the outer lid 1 and the inner lid 2 are made of transparent glass or plastic, the spring washer and the flat washer are not arranged between the nut end of the fastening screw 6 and the inner lid 2. Instead, the convex silica gel pad 10 and the concave metal pad 11 are arranged between the nut end of the fastening screw 6 and the inner lid 2 and between the first spacer column 7 and the outer lid 1, so as to prevent the outer lid 1 and the inner lid 2 from being crushed. When the outer lid 201 is made of transparent glass or plastic, only the top surface of the outer lid 201 is made of transparent glass or plastic, and the edges and / or the sidewalls of the outer lid 201 are still made of metal, for example, as shown in the drawings. Figure 4 , Figure 5 ,
