Built-in universal pressure cooker cover

The invention relates to a built-in universal pressure cooker cover, in particular to a built-in universal pressure cooker cover which is special in structure, simple and has a completely close-fit with the pot.

As far as I know, the cooking pots in the kitchen must be used with a lid. The lid of the pot is covered by the lid. On the one hand, it is to avoid heat loss and can improve the heating efficiency. On the other hand, it is based on cleanliness. The reason can prevent foreign matter from falling into the contaminated food in the pot; however, the commonly known pressure cooker can accelerate the cooking effect and shorten the cooking time by using the principle of sealing and vapor expansion, so the design of the lid is special, and the market is divided into There are several forms, such as a flat-loaded beam placed on a flat-loaded pressure cooker with a fitted set of pots, and a lid that is deformed and crimped using elastic steel to correct the elasticity of the pot with a handle. The plate-opening pressure cooker, the utility model can be screwed into the screw-in fitting type pressure cooker which is fitted and sealed with the cookware and the lid, and the horizontal card which can be enlarged and put into the pan and enlarged to seal the pan The clamp type pressure cooker and the like, the above various forms of the lid are quite complicated in structure, which not only causes trouble and time consuming to manufacture, but also has some operation difficulties. At the same time, because the lid is still quite far from the liquid surface (or boiling surface), there is still room for improvement in energy saving performance, so it has not been generally accepted and used by consumers.

In view of the shortcomings derived from the above-mentioned conventional built-in universal pressure cooker cover, the inventor of the present invention has improved and innovated, and after painstaking research, finally successfully developed and built the built-in universal pressure cooker cover.

The object of the present invention is to provide a built-in universal pressure cooker cover, wherein the annular airbag is integrally formed with the recessed groove, the air chamber and the air hole, and the air chamber is relatively far away from the outer side wall of the recessed groove. The wall thickness is thin, which is advantageous for expansion and deformation when it expands.

The built-in universal pressure cooker cover capable of achieving the above object includes: a lid body that is covered at an open end of a pot; and an annular airbag is a ring body of a predetermined size. At least one recessed groove is provided for the outer peripheral portion of the lid body to be embedded in the assembly, and the other side is formed with an air chamber having a hollow interior, and one end of the air hole is connected to the air chamber. At the other end, the steam generated in the pot can be broken in and filled in the air chamber, so that the air chamber can just resist the inner wall of the pot due to expansion and expansion, and the air is tightly closed. The pot has an open end; the support mechanism is connected to the annular airbag, and each of the support mechanisms has an extension arm of a width, and the side of the annular airbag is provided with the side of the groove to the side of the air chamber Pulling up and extending, and having an end at the end thereof, before the air chamber of the annular airbag is not vapor-expanded against the inner wall of the pot, the top of the lid body is provided to cover the opening of the pot The purpose of the end.

Referring to FIG. 1 , the built-in universal pressure cooker cover provided by the present invention mainly comprises a built-in universal pressure cooker cover, which mainly has a lid body 1 and is wound around the lid body 1 . One of the outer peripheral annular airbags 2 and at least two supporting mechanisms 3, wherein the lid body 1 is covered in a disc shape at any height position of the opening 41 or the inner wall 42 of a pot 4. The cover body is generally known to be made of glass or various metal materials. However, if the lid of the pressure cooker is usually made of a metal material, the material of the lid body 1 can also be made of a transparent material or a translucent material. Or a non-transparent material, which can also be composed of a translucent material or a non-transparent material, forming a partially transparent window 15, as shown in FIG. 3; and having a grip on the lid body 1 11 is used for grasping the handle body 1 for use. Of course, if it is a lid of a pressure cooker, it has a design of a pressure relief valve (not shown), which is a conventional and non-inventive invention. The main feature technology, so it will not be described here; the ring gas The capsule 2 is made of a silicone rubber, an elastic polymer material or an elastic material, and is formed into a ring body of a predetermined size. A groove 21 is formed on one side of the annular air bag 2, and the groove 21 is The outer peripheral edge portion of the lid body 1 is embedded in the assembly, and on the other side of the annular airbag 2, an air chamber 22 is formed which is hollow inside, and the air chamber 22 is relatively far away from the embedded chamber. The outer side wall 23 of the groove 21 has a thin wall thickness and is formed in a circular arc shape; and an air hole 24 is formed below the air chamber 22 for communicating the air chamber 22 and the inside of the pot 4, The air hole 24 is formed into a horn shape having a smaller circular diameter and a lower circular diameter; each of the supporting mechanisms 3 is also made of a flexible material, a plastic material or a hard material ( Referring to FIG. 3, at a predetermined portion of the annular airbag 2, each of the supporting mechanisms 3 has a width extending arm from the adjacent position of the annular groove 2 to the air chamber 22 The side is extended upwardly and pulled out, and is disposed at the end thereof as a top portion; wherein, the elasticity The annular airbag 2 made of the material and the supporting mechanism 3 made of a hard material form a composite structure by means of two-shot injection molding. Since the annular airbag 2 is in contact with the supporting mechanism 3, the supporting mechanism 3 supports the lid body 1 The support mechanism 3 has a phenomenon of plastic deformation with respect to the inner wall 42 of the cookware 4. On the other hand, since the soft material has the characteristics of restoring the original size and shape after the external force is removed, and the annular airbag 2 is subjected to vapor pressure into the air chamber 22, the added vapor pressure is larger than that of the elastic material. When large, the vapor inside the annular airbag 2 is squeezed outward, so that the annular airbag 2 is properly deformed to increase the airtightness of the inner wall 42 of the pan 4, so that the pan 4 appropriately increases the internal pressure to quickly cook the food. The annular airbag 2 made of the elastic material and the support mechanism 3 made of a hard material can be made of an efractory material, a heat durable plastic, and a heat durable polymer.

According to the above-mentioned invention, a built-in universal pressure cooker cover is used when the cover 41 is used at the opening 41 end of the cookware 4, as shown in Fig. 1, just before the steam is generated in the cookware 4, The abutting top of the extending arm end extended by the two supporting mechanisms 3 and longer than the outer side of the annular air bag 2 abuts against the inner wall 42 of the pot 4 to form a top body 1 For the purpose of use; or as shown in FIG. 2, the lid body 1 of the transparent material (or the partially transparent window 15) is directly lowered to the top position of the foodstuff, and the inner wall 42 of the pot 4 is attached with the annular airbag 2, When the pan 4 is heated for a period of time to heat the food and the soup in the pan 4 and generate steam, all the vapor in the pan 4 will be vented by the annular groove 2 of the annular bag 2 which is disposed around the periphery of the cap body 1. The air chamber 22 is filled and filled with the air chamber 22, and the air chamber 22 is deformed and expanded to resist the inside of the pot 4 due to the thinness of the outer side wall 23 and deformation due to thermal expansion. The wall 42 can completely close the opening 41 end of the pot 4, which can prevent the heat from being dissipated, shorten the cooking time, and complete the pressure cooker. In order to save energy and save time, the built-in universal pressure cooker cover of the present invention utilizes its special structure and space form, and when used, the pot body 1 is placed at the end of the opening 41 of the pot 4, The support mechanism 3 extending outwardly will naturally abut against the inner wall 42 of the pot 4, and cover the end 41 of the pot 4, and when the steam is heated to generate steam, the air chamber 22 of the annular airbag 2 The expansion deformation can be completely adhered to the opening 41 end (or the inner wall 42) of the pot 4, which can solve the disadvantages of the complicated structure and the difficulty of operation of the conventional pressure cooker lid.
