Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a frosted glass for kitchen stovetops. Background Technology

[0002] With the upgrading of kitchen utensils and the increasing demand for family safety, frosted glass has gradually become one of the mainstream choices for kitchen countertops due to its high temperature resistance, easy cleaning, and transparent texture. However, existing frosted glass countertops for kitchen stoves typically rely on the material's inherent heat resistance to withstand temperatures. This makes it impossible for users to visually judge temperature differences around the stove, forcing them to rely on subjective experience or repeated testing. This can easily lead to accidental contact due to misjudging the boundaries of high-temperature zones. Furthermore, existing countertops lack clear high-temperature warning labels for sensitive groups such as the elderly and children. These groups have weaker perception and reaction abilities to temperature risks, making them more prone to burns. Even if some countertops are marked with fixed high-temperature zones, it is difficult to match the real-time temperature fluctuations during actual use, and thus cannot effectively cover the safety protection needs under different cooking intensities.

[0003] Therefore, a type of frosted glass for kitchen stovetops was designed. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a frosted glass for kitchen stovetops. It solves the problem that existing frosted glass countertops for kitchen stovetops, which rely solely on the heat resistance of the material, cannot visually determine the temperature difference around the stove head and are prone to misjudgment and accidental touch due to the boundary of high-temperature zones.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A frosted glass cooktop for kitchen stovetops includes a cooktop body, a countertop, multiple thermochromic materials, and metal gaskets. The countertop is made of frosted glass and is detachably and fixedly installed on the top of the cooktop body, covering the cooking operation area of ​​the cooktop body. Multiple thermochromic materials are embedded and fixed inside the countertop, corresponding to the cooking heating area of ​​the cooktop body. The metal gaskets are fixedly embedded at the four top corners of the countertop and located inside the countertop.

[0006] Preferably, the stove body has two burners, and the multiple thermochromic materials are divided into two groups. The two groups of thermochromic materials are respectively installed at the two burners of the stove body, and each group of thermochromic materials is installed in a concentric circle with the corresponding burner.

[0007] Preferably, the multiple thermochromic materials in each group are all ring structures, and the diameter values ​​of each thermochromic material are different; with the center of the corresponding furnace head as the center, the thermochromic materials distributed outward from the center of the furnace head have an increasing diameter value.

[0008] Preferably, the metal pad has a honeycomb design, the pores of the honeycomb structure are regular hexagons, and the edge of the metal pad is attached and fixed to the inner wall of the top corner of the tabletop. The thickness of the metal pad is less than the thickness of the tabletop.

[0009] Preferably, the countertop has a raised platform integrally formed around the area near the burner head of the stove body; the raised platform is arranged around the corresponding burner head, and the top surface of the raised platform is higher than the cooking operation surface of the countertop.

[0010] Preferably, the tabletop adopts a double-layer frosted glass composite structure, and multiple thermochromic materials and metal gaskets are sandwiched between the two layers of frosted glass.

[0011] Preferably, the thermochromic material is a strip made of reversible thermochromic ink, and the color-changing temperature range of the reversible thermochromic ink is adapted to the normal temperature range of the countertop when cooking, so as to indicate the temperature status of the countertop through color changes.

[0012] Preferably, the inner diameter of the boss is matched with the outer diameter of the corresponding burner head of the stove body, and the outer diameter of the boss is larger than the outer diameter of the corresponding burner head.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a concentric circle distribution and an increasing diameter structure design, combined with reversible temperature-changing characteristics that change color at high temperatures and decrease at lower temperatures. By reflecting the temperature difference around the burner head through the color display range, the temperature-changing material in the central area changes color first, followed by the outer temperature-changing material. This transforms temperature into a visual color display, allowing users to directly determine the boundary of the high-temperature zone through the color coverage. Compared to traditional designs without temperature indication, this significantly shortens the time for identifying high-temperature zones, especially when using two burners simultaneously or during busy cooking scenarios, helping users quickly avoid dangerous high-temperature areas.

[0014] This invention reduces burner contamination by setting up a raised platform. The annular barrier, which is higher than the operating surface, prevents overflowing soup from flowing to the burner. Its inner diameter is adapted to the outer diameter of the burner, and the outer diameter is appropriately enlarged so that the overflowing soup is confined to the outer area of ​​the raised platform. Compared with a design without a raised platform, it can reduce ignition failure and oil accumulation caused by soup seeping into the burner, and reduce the frequency of stove maintenance.

Example

[0022] Please see Figure 1-5A frosted glass cooktop for kitchen countertops includes a cooktop body 1, a countertop 2, multiple thermochromic materials 22, and metal gaskets 23. The countertop 2 is made of frosted glass and is detachably and fixedly installed on top of the cooktop body 1, covering the cooking area of ​​the cooktop body 1. Multiple thermochromic materials 22 are embedded and fixed inside the countertop 2, corresponding to the cooking heating area of ​​the cooktop body 1. The metal gaskets 23 are fixedly embedded at the four corners of the countertop 2, located inside the countertop 2, to enhance the impact resistance of the corners. The cooktop body 1 has two burners, and the multiple thermochromic materials 22 are divided into two groups, with the two groups of thermochromic materials 22 respectively... The thermochromic materials 22 are installed concentrically with each burner head on the cooktop body 1. Each group of thermochromic materials 22 has a ring-shaped structure, and the diameter of each material is different. Starting from the center of the burner head, the thermochromic materials 22 are distributed outwards, with their diameters increasing sequentially. The metal gasket 23 has a honeycomb design, with hexagonal pores. The edge of the metal gasket 23 is fixed to the inner wall of the top corner of the countertop 2, and the thickness of the metal gasket 23 is less than the thickness of the countertop 2. The countertop 2 is close to the cooktop. The burner head area of ​​the main body 1 also features an integrally formed ring of protrusions 21. These protrusions 21 surround the corresponding burner head, and their top surfaces are higher than the cooking surface of the countertop 2, preventing spilled broth from flowing towards the burner head. The countertop 2 uses a double-layer frosted glass composite structure, with the two layers bonded together by a high-temperature resistant silicone layer. Multiple thermochromic materials 22 and metal gaskets 23 are sandwiched between the two layers of frosted glass, and the thermochromic materials 22, metal gaskets 23, and high-temperature resistant silicone layer are tightly bonded together. The thermochromic material 22 is a strip made of reversible thermochromic ink, and the color-changing temperature range of the reversible thermochromic ink corresponds to the temperature of the countertop 2 during cooking. The countertop 2 is temperature-adapted to a standard temperature range and uses color changes to indicate its temperature status. The metal gasket 23 is made of stainless steel to enhance impact resistance while avoiding affecting the light transmittance of the countertop 2. The inner diameter of the protrusion 21 matches the outer diameter of the corresponding burner on the cooktop body 1, and the outer diameter of the protrusion 21 is larger than the outer diameter of the corresponding burner to ensure effective blocking of spilled soup. When the surface temperature of the area corresponding to the burner on the countertop 2 is too high, the thermochromic material 22, made of reversible thermochromic ink, changes from its initial transparent state to a red state. When the surface temperature of the countertop 2 drops, the thermochromic material 22 returns to a transparent state (the thermochromic material can use reversible thermochromic ink strips). Two sets of thermochromic materials 22 are distributed in concentric circles with increasing diameters. Combined with reversible thermochromic properties, the color range reflects the temperature gradient around the burner head. The thermochromic material 22 in the center shows the highest temperature first, while the outer area shows the color later. Users can quickly determine the boundary of the high-temperature zone by the color coverage range, which is especially suitable for sensitive people such as the elderly and children, reducing the risk of accidental burns.

[0023] By embedding honeycomb stainless steel metal pads 23 at the four corners of the countertop 2, the regular hexagonal pore structure can disperse the impact stress. The high strength of stainless steel material improves the impact resistance of the top corner of the countertop 2. The thickness of the metal pads 23 is less than the thickness of the countertop 2 and the edges are attached to the inner wall without affecting the overall flatness of the countertop 2.

[0024] By setting up the protrusion 21, the contamination of the burner head can be reduced. The annular barrier above the operating surface prevents the overflow of soup from flowing to the burner head. Its inner diameter is adapted to the outer diameter of the burner head, and the outer diameter is appropriately enlarged so that the overflow of soup is limited to the outer area of ​​the protrusion 21. Compared with the design without the protrusion 21, it can reduce the problems of ignition failure and oil accumulation caused by soup seeping into the burner head, and reduce the frequency of stove maintenance.

[0025] By using a double-layer high borosilicate frosted glass composite countertop 2, and by detachably connecting the countertop 2 to the cooktop body 1, users can periodically remove the countertop 2 as a whole for cleaning, avoiding the accumulation of dirt in the gaps between the traditional fixed countertop 2 and the cooktop; and the oleophobic treatment on the frosted glass surface reduces the adhesion of oil stains.

[0026] The porous metal pad 23 enhances strength while reducing material usage, effectively preventing the countertop 2 from becoming too heavy and causing installation difficulties. The two sets of temperature-sensitive materials 22 are independently set for the two burners, and the temperature status of each burner is displayed through a dedicated concentric circle area. Users can clearly distinguish the high temperature of the left and right burners. When using two burners at the same time, they can quickly identify which burner has a higher temperature. Combined with the independent partition of the protrusion 21, it avoids cross-contamination of soup overflow when cooking on both burners at the same time.

[0027] In another implementation, the thermochromic material of each group of corresponding furnace heads is no longer a single complete ring, but is composed of 8 arc-shaped thermochromic strips with equal curvature, each arc corresponding to the central angle of the circle, spliced ​​together to form a circle; each arc-shaped thermochromic strip is independently embedded between the double-layer crystal frosted glass, and the gap between adjacent arc-shaped thermochromic strips is small, visually forming a complete circle, and the arc-shaped thermochromic strips in the same ring use the same color-changing temperature threshold. When cooking, if the cookware covers a certain area of ​​the burner, such as when heating from the side, only the arc-shaped temperature-sensitive strip in that area will change color due to localized high temperature. The arc-shaped strip in the uncovered area will remain transparent. Users can quickly identify the "localized high temperature area" by the position of the colored arc, avoiding misjudgment of overall high temperature due to the complete ring color. For example, if the cookware only covers the right side of the burner, only the four arc-shaped strips on the right side will change color, while the left side will remain transparent, indicating that the temperature in the left area is safe. If a certain arc-shaped temperature-sensitive strip fails due to aging, it is not necessary to replace the entire ring-shaped temperature-sensitive material; only the failed arc-shaped strip needs to be replaced, saving replacement costs.

[0028] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
