Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to a double-layer heat-insulating stainless steel glass pot lid. Background Technology
[0002] In the field of kitchen utensils, stainless steel glass pot lids are favored by consumers because they allow for direct observation of the cooking process inside the pot. However, traditional single-layer stainless steel glass pot lids have obvious shortcomings. Their heat insulation performance is poor, and the surface temperature of the lid is high during cooking, which can easily cause burns. In addition, heat is lost quickly, which is not conducive to the even heating of food inside the pot and energy-saving cooking. Therefore, double-layer heat insulation structure has been gradually applied to the design of stainless steel glass pot lids.
[0003] However, the existing double-layered insulated stainless steel glass pot lids still have room for improvement in structural design. When simmering a thick soup, the heat is first significantly blocked by the inner layer and the insulation layer of the lid, as it needs to be transferred to the inner wall of the pot lid. The outer glass layer is exposed to the air, while the inner layer cannot be heated to the corresponding temperature by the steam due to the blockage of the insulation layer. At this time, the high-temperature steam comes into contact with the inner wall of the pot lid, which is not compatible with its own temperature. It is equivalent to high-temperature gas encountering a low-temperature surface. The steam will quickly release heat and cool down. When the temperature drops below the dew point, the gaseous steam will immediately turn into liquid condensate.
[0004] However, in the traditional stainless steel glass pot lid structure, condensation lacks an effective guidance and collection mechanism. It can only drip randomly back into the soup under the action of gravity. If the soup needs to be boiled continuously, the frequent dripping of cold water will instantly lower the local soup temperature, causing the soup to change from a vigorous boil to an intermittent simmer. The heat control will fail. Moreover, the repeated dripping of condensation will slowly increase the total amount of soup, which is equivalent to adding extra water to the soup. This will dilute the umami flavor of the salt, spices and ingredients. Therefore, a double-layered heat-insulating stainless steel glass pot lid that can prevent most of the condensation from dripping back is needed. Utility Model Content
[0005] The purpose of this invention is to provide a double-layered heat-insulating stainless steel glass pot lid to solve the problem mentioned in the background art that most of the condensed water from the stainless steel glass pot lid will fall back into the soup during use.
[0006] To achieve the above objectives, this utility model provides the following technical solution, including a stainless steel support ring. A glass cover is mounted on the top of the stainless steel support ring. An exhaust hole is formed on the surface of the glass cover, and a fastening ring is provided within the inner cavity of the exhaust hole. A cap bead is connected to the top of the glass cover via an installation structure. A positioning ring is fixedly connected to the bottom of the stainless steel support ring. A rubber ring is fixedly connected to the inner wall of the positioning ring. A cavity is formed at the connection between the positioning ring and the rubber ring, and the cavity communicates with the inner cavity of the positioning ring. The arc-shaped portion of the glass cover and the stainless steel support ring has a double-layer structure, and the internal space of the double-layer structure of the arc-shaped portion of the glass cover and the stainless steel support ring is a vacuum cavity. Preferably, the mounting structure includes a stainless steel ring and a plastic gasket. The surface of the glass cover has mounting holes, and the plastic gasket is tightly fitted into the mounting holes. The bottom of the stainless steel ring is tightly fitted into the glass cover, the top and inner ring wall of the stainless steel ring are tightly fitted into the cover bead, and the bottom of the cover bead is tightly fitted into the plastic gasket. The plastic gasket is connected to the cover bead by bolts.
[0007] Preferably, a handle is fixedly connected to the surface of the cap bead, and the handle is in an inclined direction.
[0008] Preferably, the bottom of the glass cover and the inner cavity of the stainless steel support ring are both fixedly connected with guide strips, and the guide strips on the glass cover and the stainless steel support ring are a continuous and uninterrupted integral structure.
[0009] Compared with the prior art, the beneficial effects of this utility model are: During cooking, the high-temperature steam generated inside the pot rises and comes into contact with the inner layer of the glass cover, where it quickly condenses into water. After forming on the inner wall of the glass cover, the condensate flows downwards due to gravity and then enters through the opening at the top of the cavity between the positioning ring and the rubber ring. This prevents a large amount of condensate from randomly dripping back into the soup inside the pot, thus solving the problem that most of the condensate would fall back into the soup when using a stainless steel glass pot lid. This achieves the goal of preventing a large amount of low-temperature condensate from dripping into the high-temperature soup, disrupting the boiling process, and diluting the flavor of the soup.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0014] Example 1: Please see Figure 1-5 This utility model provides a technical solution: a double-layer heat-insulating stainless steel glass pot lid, including a stainless steel support ring 1, a glass cover 2 installed on the top of the stainless steel support ring 1, an exhaust hole on the surface of the glass cover 2, a fastening ring 3 in the inner cavity of the exhaust hole, a lid bead 4 connected to the top of the glass cover 2 by an installation structure, a positioning ring 5 fixedly connected to the bottom of the stainless steel support ring 1, a rubber ring 6 fixedly connected to the inner wall of the positioning ring 5, a cavity formed at the connection between the positioning ring 5 and the rubber ring 6, the cavity communicating with the inner cavity of the positioning ring 5, the arc-shaped portion of the glass cover 2 and the stainless steel support ring 1 is a double-layer structure, and the internal space of the double-layer structure of the arc-shaped portion of the glass cover 2 and the stainless steel support ring 1 is a vacuum cavity. Analysis of the above content: During cooking, the high-temperature steam generated inside the pot will exert upward pressure on the lid. At this time, the vent on the glass cover 2 can directly connect the inside of the pot with the outside environment, directing the excess steam out and keeping the pressure inside the pot within a safe range (in normal pressure cooking scenarios, it is usually kept basically consistent with the outside air pressure). At the same time, the fastening ring 3 can prevent the vent from deforming or cracking due to long-term high-temperature use.
[0015] When the high-temperature steam rises and contacts the inner layer of the glass cover 2 and the stainless steel support ring 1 (due to the double-layer structure, the arc-shaped part of the glass cover 2 and the stainless steel support ring 1 is divided into an inner layer and an outer layer. The air between the two layers of glass is extracted, forming a vacuum environment with few or no air molecules, which weakens the heat exchange between the inner layer of glass and the outer environment from the source, achieving the effect of double-layer insulation. The fastening ring 3 seals the vacuum cavity at the exhaust hole on the glass cover 2 to prevent outside air from entering), due to the mismatch between the inner layer temperature and the high-temperature steam, it will quickly condense into condensate. After the condensate forms on the inner wall of the glass cover 2, it will flow downward along the inner wall due to gravity, and then pass through the positioning ring 5 and the rubber ring. The opening at the top of the cavity 6 allows water to enter (the rubber ring 6 can fold its inner wall out through its elastic structure, making it easy to clean the cavity and the inner cavity of the positioning ring 5), preventing it from dripping back into the soup in the pot. This process avoids a large amount of low-temperature condensate dripping into the high-temperature soup, which would disrupt the boiling state and dilute the flavor of the soup. It also reduces the shape damage caused by water droplets impacting the ingredients, ensuring the cooking effect. (Furthermore, when the lid is placed upright, the condensate remaining on the inner wall of the glass cover 2 will enter the cavity between the positioning ring 5 and the rubber ring 6 due to gravity, preventing it from flowing directly onto the table.) This solves the problem that most of the condensate from the stainless steel glass lid will fall back into the soup during use.
[0016] Example 2: Please see Figure 1-5 This utility model provides a technical solution based on Embodiment 1: the mounting structure includes a stainless steel ring 8 and a plastic gasket 9. The surface of the glass cover 2 is provided with mounting holes, and the plastic gasket 9 is tightly fitted in the mounting holes. The bottom of the stainless steel ring 8 is tightly fitted with the glass cover 2, the top and inner ring wall of the stainless steel ring 8 are tightly fitted with the cover bead 4, and the bottom of the cover bead 4 is tightly fitted with the plastic gasket 9. The plastic gasket 9 is connected to the cover bead 4 by bolts.
[0017] Analysis of the above: During installation, the user first inserts the plastic gasket 9 axially into the mounting hole from the bottom of the glass cover 2. Then, the stainless steel ring 8 is placed on the top surface of the glass cover 2 and fully adhered. Next, the cap bead 4 is pressed against the top of the stainless steel ring 8 and adhered. At the same time, the convex part at the bottom center (this convex structure is cylindrical, and its outer diameter matches the inner ring wall diameter of the stainless steel ring 8) is inserted into the inner ring wall of the stainless steel ring 8 and then connected with the plastic gasket 9. Finally, the stainless steel ring 8, plastic gasket 9, and cap bead 4 are connected by bolts (nylon material can be used). The stainless steel ring 8 increases the friction between itself and the glass cover 2 by pressing against itself through the cap bead 4. The friction in the mounting hole of the glass cover 2 is further increased by the plastic gasket 9. Under the combined action of the friction between the stainless steel ring 8 and the surface of the glass cover 2, and the friction between the plastic gasket 9 and the wall of the mounting hole, the cap bead 4 is restricted to a fixed position and cannot rotate around the axis.
[0018] Example 3: Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: a handle 10 is fixedly connected to the surface of the cover bead 4, and the handle 10 is in an inclined direction.
[0019] Analysis of the above content: By setting the handle 10, the pot lid can be more easily picked up. At the same time, the outward tilt of the handle 10 creates a three-point support between the pot lid and the handle 10 when it is placed upright, which increases the stability of its support surface and prevents it from tipping over.
[0020] Example 4: Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: the bottom of the glass cover 2 and the inner cavity of the stainless steel support ring 1 are both fixedly connected with guide strips 7, and the guide strips 7 on the glass cover 2 and the stainless steel support ring 1 are a continuous and uninterrupted integral structure.
[0021] Analysis of the above content: When the condensed water moves along the inner wall of the arc-shaped part of the glass cover 2 and the stainless steel support ring 1, the guide strip 7 at the bottom of the glass cover 2 (distributed along the radial or circumferential direction of the glass cover 2) will directly contact the condensed water. When it flows through the guide strip 7 and the guide groove formed by the separation of the adjacent guide strip 7, it will be intercepted and guided by the arc-shaped structure of the guide strip 7 and the guide groove (guided to the stainless steel support ring 1 at the edge of the pot lid), so that the condensed water can quickly flow into the cavity between the positioning ring 5 and the rubber ring 6.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
