Description

Technical Field

[0001] The utility model belongs to the technical field of water boiling appliances, and particularly relates to a water boiling kettle body with rough side walls and a water boiling appliance. Background Art

[0002] As an essential household appliance, the performance and quality of kettles are directly related to people's drinking water safety and health. With increasing demands for water quality, especially when it comes to meeting high purity standards with a TDS (Total Dissolved Solids) level below 10 mg / L, kettles have smooth inner surfaces and lack vaporization centers (air dissolved in the liquid or adsorbed in thin films on the kettle walls, which contribute to the formation of small bubbles, known as vaporization centers). This can lead to water not boiling even after exceeding its boiling point, a phenomenon known as thermal hysteresis. Furthermore, when a pure liquid reaches an overheated state, bubbles will rapidly expand, causing the liquid to boil violently and potentially burst out of the kettle, resulting in a sudden boil. These issues not only affect the normal use of kettles but also pose a serious threat to consumer safety, leading to more stringent performance requirements for kettles.

[0003] Currently, the existing technology uses a roughened surface on the bottom of a kettle to provide a vaporization center, thereby reducing the risk of thermal hysteresis and explosive boiling. However, due to gravity, liquid easily accumulates at the bottom of the kettle, and the roughened surface is not conducive to cleaning. Moreover, if the roughened surface is achieved using a coating, the coating may be damaged during routine cleaning, which is not conducive to preventing thermal hysteresis and explosive boiling. In response to the problems existing in the existing technology, it is urgently needed to provide a kettle body and water boiling device with roughened sidewalls that are convenient for daily cleaning and can effectively prevent thermal hysteresis and explosive boiling. Summary of the Invention

[0004] In view of the problems in the related art, the present invention proposes a water boiling kettle body and a water boiling utensil with rough side walls to overcome the above technical problems existing in the existing related art.

[0005] The technical solution of the present utility model is achieved as follows: a water boiling kettle body with rough side walls comprises a kettle body, the kettle body having an inner cavity for holding liquid to be heated; the upper end of the kettle body is open, and the opening is communicated with the inner cavity; the kettle body is placed on a heating module, and the bottom of the kettle body and the heating module are fixedly connected to or separately arranged; the kettle body comprises a kettle body, and the kettle body has a flat heating end portion at the bottom, and the heating end portion is against or separated from the heating module; the inner surface of the kettle body at the heating end portion is a smooth surface, and the kettle body is provided with a rough surface on the circumferential cavity wall of the heating end portion, and the rough surface is adjacent to the heating end portion.

[0006] In the present invention, the inner surface of the cavity bottom where the kettle body contacts the heating module is set to a smooth surface, which is convenient for cleaning the cavity bottom; at the same time, the inner surface of the cavity wall that is not in contact with the heating module is set to a rough surface. Since the liquid flows to the cavity bottom under the action of gravity, it will not cause the wall to be difficult to clean; the rough surface on the cavity wall can promote the small bubbles generated during the heating process to escape from the water surface, effectively reducing the accumulation and sudden release of bubbles in the water, thereby reducing the possibility of boiling.

[0007] As a further improvement of the above solution, the rough surface is formed by mold shaping, sandblasting, laser engraving or grinding.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] As a further improvement to the above solution, the roughened surface includes multiple protrusions, with concave portions formed between adjacent protrusions, and a distance difference between the outer edges of the protrusions and the inner edges of the concave portions. Furthermore, the multiple protrusions are in the form of points, surfaces, or strips. By shaping the interior of the kettle with protrusions and concave portions, the concave and convex pattern can provide a vaporization center within the kettle, effectively reducing the phenomenon of non-boiling and explosive boiling.

[0013] As a further improvement of the above solution, the kettle body is made of glass.

[0014] As a further improvement of the above solution, the rough surface is annular and distributed upward from the heated end around the circumferential cavity wall;

[0015] Alternatively, the rough surface is in the form of strips, distributed on one or more sides of the cavity wall, and linearly extending upward from the heated end;

[0016] Alternatively, the rough surface is in the form of scattered points, starting from the heated end and upwards, completely or partially filling the cavity wall.

[0017] It should be noted that the linear or circular distribution of annular or strip-shaped rough surfaces, as well as the random distribution of scattered point-shaped rough surfaces, can guide the formation and rise of bubbles to a certain extent. These designs allow bubbles to gradually merge into larger bubbles during their rise and release them smoothly to the water surface, thus avoiding the boiling phenomenon caused by rapid bubble expansion.

[0018] As a further improvement of the above solution, the heating module is a resistance heating module, comprising a conduction disk and a heating tube; the upper end of the conduction disk is adapted to the bottom of the kettle body, and the lower end of the conduction disk is provided with the heating tube;

[0019] The heating pipe includes a starting end, an ending end and a heating pipe body; the heating pipe body extends from the starting end along the plane where the conduction disk is located to the ending end, and is connected to an external power supply module through the starting end and the ending end respectively.

[0020] As a further improvement of the above solution, the heating module is an induction heating module, the bottom of the kettle body is hollow, and a magnetic bottom plate is embedded in the hollow; or a magnetic bottom plate is connected to the outer side of the bottom of the kettle body;

[0021] The induction heating module includes an electromagnetic heater, which inductively cooperates with the magnetic bottom plate of the kettle body to heat the liquid in the inner cavity.

[0022] As a further improvement to the above solution, the kettle body contracts at the opening and extends upward to form a spout, the width of which is smaller than the width of the heated end. A water spout angled upward is provided on one side of the kettle body, and a handle is provided on the other side. The design of the kettle body contracting at the opening and extending upward to form the spout makes the width of the spout smaller than the width of the heated end, allowing for more concentrated heat transfer into the kettle during the heating process. Due to the smaller size of the spout, heat is relatively concentrated in the spout area, reducing heat loss and improving heating efficiency.

[0023] The utility model also provides a water boiling utensil, comprising the above-mentioned water boiling kettle body with rough side walls, which is convenient for daily cleaning and can effectively avoid thermal lag and boiling defects.

[0024] Beneficial effects of the utility model:

[0025] The inner surface of the bottom of the kettle, where the kettle body contacts the heating module, is smooth, making it easier to clean. Meanwhile, the inner surface of the wall, which is not in contact with the heating module, is roughened. As liquid flows to the bottom under gravity, it doesn't cling to the wall, making it difficult to clean. The roughened surface of the wall encourages small bubbles generated during heating to escape the water, effectively reducing their accumulation and sudden release, thereby reducing the possibility of explosive boiling. Furthermore, by placing the roughened surface adjacent to the heated end, even when the kettle is low in liquid, it effectively provides a vaporization center for bubble generation, preventing explosive boiling.

[0041] 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.

[0042] Example 1

[0043] like Figure 1-Figure 4 As shown, this embodiment provides a water boiling device, including a kettle body with rough sidewalls. While facilitating daily cleaning, it also effectively prevents thermal hysteresis and explosive boiling. Specifically, the kettle body with rough sidewalls includes a kettle body 1 having an inner cavity 11 for containing a liquid to be heated; the liquid may be purified water.

[0044] In this embodiment, the kettle body 1 is made of glass, which has high transparency, is easy to clean, and allows for observing changes in water quality. The upper end of the kettle body 1 is opened 12, and the opening 12 is interconnected with the inner cavity 11; the kettle body 1 is placed on the heating module 2, and the bottom of the kettle body 1 is fixedly connected to or separated from the heating module 2; the kettle body 1 includes a kettle body 13, and the kettle body 13 has a flat heated end portion 131 at the bottom, and the heated end portion 131 is against or separated from the heating module 2; in this embodiment, 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 heated end portion 131; a water outlet 14 is provided on one side of the kettle body 13, and a handle 15 is provided on the other side. The kettle body 13 converges at the opening 12 and extends upward to form the spout 121. This makes the width of the spout 121 smaller than the width of the heated end 131. This allows for more concentrated heat transfer into the kettle during heating. Due to the smaller size of the spout 121, heat is relatively concentrated in the spout 121 area, reducing heat loss and improving heating efficiency.

[0045] The inner surface of the kettle body 1 at the heated end 131 is a smooth surface 4 , and the kettle body 1 is provided with a rough surface 3 on the circumferential cavity wall of the heated end 131 , and the rough surface 3 is adjacent to the heated end 131 .

[0046] In this embodiment, the rough surface 3 comprises multiple convex portions, with concave portions formed between adjacent convex portions, and a distance difference between the outer edges of the convex portions and the inner edges of the concave portions. Furthermore, the multiple convex portions are in the form of points, surfaces, or strips. By shaping the interior of the kettle with convex and concave portions, the concave and convex pattern can provide a vaporization center within the kettle, effectively reducing the phenomenon of non-boiling and explosive boiling.

[0047] In this embodiment, the roughened surface 3 is annular, extending upward from the heated end 131 and circumferentially around the cavity wall. The presence of the annular roughened surface 3 can, to a certain extent, guide the formation and rise of bubbles. This design allows the bubbles to gradually merge into larger bubbles during their rise and be released smoothly to the water surface, thus avoiding sudden boiling caused by rapid bubble expansion.

[0048] In this embodiment, the rough surface 3 is formed by mold shaping, sandblasting, laser engraving or grinding.

[0049] Mold shaping can accurately give the inner wall a specific rough texture during the kettle 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 kettle 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 kettle 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. Polishing physically removes the smooth layer on the glass surface to form a rough surface 3, which helps to enhance the friction of the inner wall and remove defects in the production process. While ensuring the quality of the kettle body, it effectively solves the phenomenon of non-boiling and boiling.

[0050] In this embodiment, the heating module 2 is a resistance heating module, comprising a conduction disc 21 and a heating tube 22; the upper end of the conduction disc 21 is adapted to the bottom of the kettle body 1, and the lower end of the conduction disc 21 is provided with the heating tube 22;

[0051] The heat pipe 22 includes a starting end 221, a terminal end 222, and a heat pipe body 223. The heat pipe body 223 extends from the starting end 221 along the plane of the conductive plate 21 to the terminal end 222. The starting end 221 and the terminal end 222 are connected to an external power supply module. The power supply module can be a power supply or a battery. The two ends of each heat pipe 22 are connected to the electrodes of the power supply module to convert electrical energy into heat energy, thereby achieving the heating function.

[0052] In other embodiments, the heating module 2 can also be an induction heating module, the bottom of the kettle body 1 is hollow, and a magnetic bottom plate is embedded in the hollow part; or, a magnetic bottom plate is connected to the outer side of the bottom of the kettle body 1 (not shown in the figure); the induction heating module includes an electromagnetic heater, and the electromagnetic heater cooperates with the magnetic bottom plate of the kettle body 1 by induction to heat the liquid in the inner cavity 11.

[0053] Through the above-mentioned scheme of the present invention, in specific applications: the inner surface of the cavity bottom where the kettle body 1 contacts the heating module 2 is set to a smooth surface 4, which is convenient for cleaning the cavity bottom; at the same time, the inner surface of the cavity wall that is not in contact with the heating module 2 is set to a rough surface 3. Since the liquid flows to the cavity bottom under the action of gravity, it will not cause the wall to be difficult to clean; the rough surface 3 on the cavity wall can promote the small bubbles generated during the heating process to escape from the water surface, effectively reducing the accumulation and sudden release of bubbles in the water, thereby reducing the possibility of boiling.

[0054] Example 2

[0055] One of the implementation methods of the present utility model, 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] The roughened surface 3 is strip-shaped and distributed on one or more sides of the cavity wall, extending linearly upward from the heated end 131. The linear distribution of the roughened surface 3 can, to a certain extent, guide the formation and ascent of bubbles. This design allows bubbles to gradually merge into larger bubbles during their ascent and be released smoothly to the water surface, thus avoiding sudden boiling caused by rapid bubble expansion.

[0057] Example 3

[0058] One of the implementation methods of the present utility model, 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:

[0059] The rough surface 3 is scattered, extending upward from the heated end 131, completely or partially filling the cavity wall. The random distribution of the scattered rough surface 3 can, to a certain extent, guide the formation and rise of bubbles. This design allows bubbles to gradually merge into larger bubbles during their rise and be released smoothly to the water surface, thus avoiding the phenomenon of explosive boiling caused by rapid bubble expansion.
