Description
Technical Field
[0001] The utility model belongs to the technical field of kettles, and particularly relates to a kettle body structure with local textures and a kettle. Background Art
[0002] As living standards continue to improve, people's requirements for drinking water quality are becoming increasingly stringent. As an indispensable electrical appliance in household life, the performance and quality of kettles directly affect people's drinking water safety and health. Currently, there are many types of kettles on the market, ranging from stainless steel and ceramic to glass. Glass kettles are popular among consumers due to their high transparency, ease of cleaning, and ability to observe changes in water quality. However, as people's requirements for water quality continue to rise, especially when water quality reaches the purity standard of less than 10mg / L (Total Dissolved Solids), higher performance requirements are placed on kettles.
[0003] Common glass kettles typically have a smooth inner surface. While this design is aesthetically pleasing and easy to clean, it poses a safety hazard during the heating process. When the water is relatively pure, the pure liquid lacks vaporization centers (the air dissolved in the liquid or adsorbed on the bottle wall in the form of a thin film contributes to the formation of small bubbles, while the smooth glass surface makes it difficult to provide such vaporization centers). Therefore, the water often does not boil even after being heated above its boiling point, a phenomenon known as thermal hysteresis. Furthermore, once the pure liquid becomes superheated, if a bubble forms, it will rapidly grow and cause the liquid to boil violently, even overflowing the kettle, a phenomenon known as explosive boiling. Existing glass kettles, especially when the water quality reaches a high level of purity, face the safety hazard of not boiling or explosive boiling during the heating process. These phenomena not only affect the normal use of kettles but may also pose a threat to consumer safety. After in-depth research, the inventors discovered that heat from the heating source in a kettle is first transferred to the bottom of the kettle body, where it is heated first. However, due to the smooth surface of traditional kettle bottoms, vaporization centers are difficult to form, which increases the risk of thermal hysteresis and explosive boiling. Therefore, it is urgent to design a specific texture or structure on the bottom of the kettle body to increase the number and distribution of vaporization centers, thereby effectively preventing thermal hysteresis and explosive boiling. Summary of the Invention
[0004] In view of the problems in the related art, the present invention proposes a kettle body structure with local texture and a kettle for boiling water to overcome the above technical problems existing in the existing related art.
[0005] The technical solution of the utility model is achieved as follows: a kettle body structure with local texture includes a kettle body with a cavity, the cavity is used to hold liquid to be heated; the upper end of the kettle body is open, and the opening is connected to the cavity; the kettle body is placed on a heating source, and the bottom of the kettle body and the heating source are fixedly connected or separated;
[0006] The heating source includes a heat conducting plate and a heating tube; the upper end of the heat conducting plate is adapted to the bottom of the kettle body, and the lower end of the heat conducting plate is provided with the heating tube; the heating tube includes a starting end, an ending end and a heating tube body; the heating tube body extends from the starting end along the plane where the heat conducting plate is located to the ending end, and is connected to an external power supply module through the starting end and the ending end respectively; a textured portion is provided on the inner surface of the bottom of the kettle body, and an extension path of the textured portion is adapted to an extension path of the heating tube body.
[0007] In the present utility model, by optimizing the heating structure and the texture design on the inner side of the bottom of the kettle body, the uniformity and stability of the heating process are effectively improved, and the thermal lag and boiling risk when heating pure water are significantly reduced.
[0008] As a further improvement of the above solution, the texture portion is formed by mold shaping, sandblasting, laser engraving or grinding.
[0009] The mold shape can accurately give the inner wall a specific rough texture during the pot body forming stage. This not only ensures the consistency and uniformity of the texture, but also greatly improves production efficiency and reduces the cost of subsequent processing, so that the pot body has better anti-explosion performance while maintaining its beauty.
[0010] Sandblasting uses high-speed jets of sand to hit the glass surface, forming tiny concave and convex structures. These structures visually increase the sense of layering and enhance the texture of the product. They can also provide a vaporization center inside the pot body, improving the phenomenon of non-boiling and boiling.
[0011] Laser engraving mainly uses high-energy laser beams to perform micro-engraving on the glass surface. It can accurately control the shape, size and depth of the texture, increase the roughness of the inner wall, and avoid boiling.
[0012] The polishing process physically removes the smooth layer on the glass surface to form a rough surface, which helps to increase the friction of the inner wall and remove defects in the production process. While ensuring the quality of the pot body, it effectively solves the problems of non-boiling and boiling.
[0013] As a further improvement to the above solution, the heat pipe body extends along a circular arc, with a gap between the starting and ending points. The corresponding extension path of the textured portion is an open circular arc or a closed circle. This design of the heat pipe body extending along a circular arc allows for more effective heat dissipation. The circular arc shape allows heat to be more evenly distributed across the heated object, reducing localized overheating caused by concentrated heat.
[0014] As a further improvement to the above solution, the heat pipe body gradually extends inward from the starting end in the same direction of rotation to the end, with the starting and ending ends of the heat pipe being staggered. This design ensures that heat is distributed along a smooth and continuous path during transfer. This wraparound layout allows heat to more evenly cover the heated area, effectively avoiding localized overheating or insufficient heating.
[0015] As a further improvement to the above solution, the heating tube body extends along a reciprocating curve, with the starting and ending points of the heating tube located on the same or opposite sides. This design significantly improves the uniformity of the heating area. The reciprocating curve allows the heating tube to more fully contact the heated object, distributing heat evenly along the curve and avoiding the uneven heating problem caused by straight lines or simple curves.
[0016] As a further improvement to the above solution, the textured portion includes multiple raised portions naturally arranged on the bottom inner surface of the kettle body; the raised portions are in the form of dots, surfaces, or strips, with recesses formed between adjacent raised portions, and a height difference between the upper edge of the raised portion and the lower edge of the recess. By locally shaping the interior of the kettle body with raised and recessed portions, the concave and convex pattern can provide a vaporization center within the kettle body, effectively reducing the phenomenon of non-boiling and explosive boiling.
[0017] As a further improvement of the above solution, the kettle body includes a kettle body, the kettle body has a flat heating end portion at the bottom, and the textured portion is provided on the heating end portion; the kettle body contracts at the opening and extends upward to form a kettle mouth, and the width dimension of the kettle mouth is smaller than the width dimension of the heating end portion. The kettle body has a flat heating end portion at the bottom, so that the kettle can be placed more stably on the heating source. The flat heating end portion ensures that heat can be evenly and efficiently transferred to the water inside the kettle, thereby improving heating efficiency and shortening boiling time. Secondly, the kettle body contracts at the opening and extends upward to form a kettle mouth, and the width dimension of the kettle mouth is smaller than the width dimension of the heating end portion, which not only makes the appearance of the kettle body more beautiful and practical, but also helps to reduce heat loss at the kettle mouth. The smaller kettle mouth size can reduce heat convection and radiation loss, so that more heat can be retained inside the kettle, which is conducive to heating and boiling water.
[0018] As a further improvement to the above solution, the width dimension of the layout area of the texture portion is smaller than the width dimension of the heating end portion and slightly larger than the width dimension of the pot mouth. It should be noted that the texture portion can be made using physical or chemical methods. If the formed kettle body is processed, since the texture portion is arranged on the inner side of the bottom, it is limited by the size of the pot mouth and the layout area of the texture portion should not be too large. The so-called width dimension of the texture portion is slightly larger than the width dimension of the pot mouth means that the width dimension of the texture portion is 1.1 to 1.6 times the width dimension of the pot mouth.
[0019] As a further improvement of the above solution, the kettle body is made of glass, and a water spout tilted upward is provided on one side of the kettle body, and a handle is provided on the other side.
[0020] The utility model also provides a kettle, comprising a kettle body structure with local texture as described above, which shows a significant effect in avoiding the boiling phenomenon during the heating process of pure water.
[0021] Beneficial effects of the utility model:
[0022] (1) Promoting the escape of bubbles: The layout area of the textured portion is determined according to the extension path of the heating tube. This area is the first location of the kettle body to be heated, and the heat of the heating tube is transferred from this area to the interior of the kettle body. The extension path of the textured portion is adapted to the extension path of the heating tube body, which can promote the escape of small bubbles generated during the heating process from the water surface, effectively reducing the accumulation and sudden release of bubbles in the water, thereby reducing the possibility of boiling.
[0023] (2) Enhanced heating stability: The combined use of the heat conducting plate and the heating tube makes the heating more stable and controllable, reduces the problem of hot spot concentration caused by the direct contact of the heating element with the bottom of the kettle, further ensures the stability of the heating process, and helps to avoid the boiling of pure water due to rapid heating.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0040] Example 1
[0041] like Figure 1-Figure 5As shown, this embodiment provides a kettle having a partially textured body structure, which exhibits significant effectiveness in preventing boilover during the heating of purified water. Specifically, the kettle body structure having a partially textured body structure includes a kettle body 1 having a cavity 11, wherein the cavity 11 is used to hold a liquid to be heated; the liquid may be purified water.
[0042] The kettle body 1 has an opening 12 at the top, which communicates with the cavity 11. In this embodiment, the kettle body 1 is made of glass, with a water spout 14 angled upward on one side of the kettle body 13 and a handle 15 on the other side. The glass kettle body 1 is highly transparent, easy to clean, and convenient for observing changes in water quality. In this embodiment, the kettle body 1 includes a kettle body 13 having a flat heating end 131 at the bottom, with the textured portion 3 disposed on the heating end 131. The kettle body 13 contracts at the opening 12 and extends upward to form a spout 121, the width of which is smaller than the width of the heating end 131. The flat heating end 131 at the bottom of the kettle body 13 allows the kettle to be placed more stably on the heating source 2. The flat heating end 131 ensures that heat is evenly and efficiently transferred to the water within the kettle, improving heating efficiency and shortening boiling time. Secondly, the kettle body 13 contracts at the opening 12 and extends upward to form a kettle mouth 121, and the width of the kettle mouth 121 is smaller than the width of the heating end 131, which not only makes the appearance of the kettle body 1 more beautiful and practical, but also helps to reduce the loss of heat at the kettle mouth 121. The smaller size of the kettle mouth 121 can reduce the convection and radiation loss of heat, so that more heat can be retained inside the kettle, which is conducive to heating and boiling water.
[0043] In this embodiment, the width of the area where the textured portion 3 is arranged is smaller than the width of the heating end portion 131 and slightly larger than the width of the spout 121. It should be noted that the textured portion 3 can be formed using physical or chemical methods. If the kettle body 1 is processed, the textured portion 3 is located on the inner side of the bottom, and the size of the spout 121 is limited, so the area where the textured portion 3 is arranged should not be too large. The so-called width of the textured portion 3 is slightly larger than the width of the spout 121, which means that the width of the textured portion 3 is 1.1 to 1.6 times the width of the spout 121.
[0044] The outer side of the bottom of the kettle body 1 is against or separated from the heating source 2, and the heating source 2 is used to heat the liquid in the cavity 11; the kettle body 1 and the heating source 2 can be fixedly connected or separated from each other.
[0045] The heating source 2 includes a heat-conducting plate 21 and a heating tube 22; the upper end of the heat-conducting plate 21 is adapted to the bottom of the kettle body 1, and the lower end of the heat-conducting plate 21 is provided with the heating tube 22; the heating tube 22 includes a starting end 221, an ending end 222 and a heating tube body 223; the heating tube body 223 extends from the starting end 221 along the plane where the heat-conducting plate 21 is located to the ending end 222, and is respectively connected to an external power supply module through the starting end 221 and the ending end 222; the power supply module can be a power supply or a battery, and the two ends of each heating tube 22 are respectively connected to the electrodes of the power supply module to convert electrical energy into thermal energy to realize the heating function.
[0046] The inner surface of the bottom of the kettle body 1 is provided with a texture portion 3, and the extension path of the texture portion 3 is adapted to the extension path of the heating tube body 223. Specifically, the heating tube body 223 extends along an arc segment, and there is a gap between the starting end 221 and the end end 222 of the heating tube 22; the extension path corresponding to the texture portion 3 is an open arc segment; or a closed circle. The design of the heating tube body 223 extending along the arc segment can disperse heat more effectively. The arc shape allows the heat to be more evenly distributed on the heated object during the propagation process, reducing local overheating caused by heat concentration.
[0047] In this embodiment, the textured portion 3 comprises a plurality of protrusions 31 naturally arranged on the bottom inner surface of the kettle body 1. These protrusions 31 are arranged in a dotted, planar, or striped pattern, with recesses 32 formed between adjacent protrusions 31. A height difference exists between the upper edge of each protrusion 31 and the lower edge of each recess 32. By locally shaping the protrusions 31 and recesses 32 within the kettle body, the concave and convex pattern creates a vaporization center within the kettle body, effectively alleviating the phenomenon of non-boiling and explosive boiling.
[0048] In this embodiment, the texture portion 3 is formed by mold shaping, sandblasting, laser engraving or grinding.
[0049] Among them, mold shaping can accurately give the inner wall a specific rough texture during the pot body forming stage, which not only ensures the consistency and uniformity of the texture, but also greatly improves production efficiency and reduces the cost of subsequent processing, so that the pot body has better anti-explosion performance while maintaining its beauty. Sand blasting uses high-speed sprayed sand to hit the glass surface to form tiny concave and convex structures. These structures visually increase the sense of layering and enhance the texture of the product. They can also provide a vaporization center inside the pot body to improve the phenomenon of non-boiling and boiling. Laser carving mainly uses a high-energy laser beam to perform micro-engraving on the glass surface. It can accurately control the shape, size and depth of the texture, increase the roughness of the inner wall, and avoid boiling. The polishing process physically removes the smooth layer on the glass surface to form a rough surface, which helps to increase the friction of the inner wall and remove defects in the production process. While ensuring the quality of the pot body, it effectively solves the phenomenon of non-boiling and boiling.
[0050] The above-mentioned solution of the present invention, in a specific application, provides a kettle body structure with a localized texture. The layout area of the textured portion 3 is determined according to the extension path of the heating tube 22. This area is the first location on the kettle body 1 to be heated, and the heat from the heating tube 22 is transferred from this area to the interior of the kettle body. The extension path of the textured portion 3 is configured to match the extension path of the heating tube body 223, which can promote the escape of small bubbles generated during the heating process to the water surface, effectively reducing the accumulation and sudden release of bubbles in the water, thereby reducing the possibility of boiling.
[0051] Example 2
[0052] like Figure 6 As shown, this is one of the embodiments of the present invention. The main technical solution of this embodiment is the same as that of Example 1. The features not explained in this embodiment are explained in Example 1 and will not be repeated here. The difference between this embodiment and Example 1 is:
[0053] In this embodiment, the heat pipe bodies 223 extend gradually inward from the starting end 221 in the same rotational direction to the end 222, with the starting end 221 and the end 222 of the heat pipe 22 being staggered. This design of the heat pipe bodies 223 extending gradually inward from the starting end 221 in the same rotational direction to the end 222 ensures that heat is distributed along a smooth and continuous path during transfer. This wraparound layout allows heat to more evenly cover the heated area, effectively avoiding localized overheating or insufficient heating.
[0054] Example 3
[0055] like Figure 7As shown, this is one of the embodiments of the present invention. The main technical solution of this embodiment is the same as that of Example 1. The features not explained in this embodiment are explained in Example 1 and will not be repeated here. The difference between this embodiment and Example 1 is:
[0056] In this embodiment, the heat pipe body 223 extends along a reciprocating curve, with the starting end 221 and the ending end 222 of the heat pipe 22 located on the same side or opposite sides. This design significantly improves the uniformity of the heating area. The reciprocating curve allows the heat pipe 22 to more fully contact the heated object, distributing heat evenly along the curve and avoiding the uneven heating problem caused by straight lines or simple curves.
[0057] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation to the present invention.
