The application provides a boiling water pot that noise reduction effect is good, including the kettle body 100 with set up in the heating element 200 of kettle body 100 bottom, heating element 200 includes heat conduction dish 210 and locates the heating pipe 220 of heat conduction dish 210 lower surface, heat conduction dish 210 is including the installation department 211 that is used for installing heating pipe 220, at least one side surface of installation department 211 is equipped with recess 300 along the circumference of heating pipe 220 to reduce the transmission of the heat that heating pipe 220 produced in installation department 211 thickness direction.

Thus, the groove 300 is formed on the surface of at least one side of the mounting part 211 along the circumferential direction of the heating tube 220, so that when the heating tube 220 heats the heat conducting disc 210, the groove 300 can reduce the heat transfer in the thickness direction of the mounting part 211, force more heat to flow in the heat conducting disc 210 along the radial direction, improve the temperature uniformity of the heat conducting disc 210, and uniformly heat the kettle body 100, thereby avoiding the problem that the bubbles generated in a partial region are faster due to the non-uniform temperature of the heat conducting disc 210, and reducing the noise generated by the burst bubbles during heating.

Example one

As shown in FIG. 1, the main structure of the kettle body 100 includes an inner container 110, a temperature controller 120, a housing 130, a lid 140, and a bottom plate 150. The inner container 110 forms a receiving chamber 111 for receiving and heating the water. The temperature controller 120 arranged at the lower part of the inner container 110 realizes the input of power and the stop of the heating of the water in the inner container 110. The outer shell 130 and the bottom plate 150 fix the inner container 110, and have heat insulation and noise reduction functions, and the outer shell 130 or the inner container 110 can be further provided with a handle 160. The cup cover 140 is assembled on the upper part of the handle 160, which is convenient for adding water and dust, and enables high-temperature steam to flow to the temperature controller 120 through a steam pipeline, thereby realizing the stop of water heating. The inner container 110 is formed by a bottom surface and a side surface to form an accommodating cavity 111 structure with an opening at the upper part, the bottom surface is a metal structure, the side surface can be made of the same material as the bottom surface or other materials, and the heating pipe 220 and the heat conducting disc 210 are arranged between the bottom surface of the inner container 110 and the bottom plate 150. The heat conducting plate 210 is made of a material having a heat transfer coefficient greater than 100W/m DEG C, such as aluminum heat conducting plate 210. The heating tube 220, the heat conducting plate 210 and the inner container 110 are generally welded and fixed, and other fixing methods (such as bolts, nuts, etc.) may also be adopted.

It is understood that the mounting portion 211 is an annular body near the edge of the heat conducting plate 210, and the heating pipe 220 is arc-shaped and is disposed around the lower surface of the mounting portion 211. Since the heat transfer in the thickness direction of the heat conducting plate 210 is stronger than that in the flat direction, when the heating pipe 220 is heated, the heat is rapidly transferred from the lower surface to the upper surface in the longitudinal direction of the heat conducting plate 210, and the heat flowing in the radial direction of the heat conducting plate 210 is relatively less. Therefore, the temperature of the outer ring of the thermal conductive disk 210 at the mounting portion 211 where the heat pipe 220 is mounted is fast, and the temperature of the inner ring of the thermal conductive disk 210 at a position where the heat pipe 220 is not mounted is slow, which results in uneven temperature of the thermal conductive disk 210.

After the groove 300 is circumferentially formed on the surface of the heat conducting disc 210 corresponding to the mounting portion 211 of the heating pipe 220, heat cannot flow along the heat conducting disc 210 in a large amount longitudinally, so that the amount of heat flowing along the radial direction in the heat conducting disc 210 can be increased, the overall temperature of the heat conducting disc 210 is uniform, heat exchange with the bottom of the kettle body 100 is uniform, and noise caused by local rapid bubble generation and burst due to local over-high temperature is reduced.

As shown in fig. 2, in one embodiment, a recess 300 is provided in an upper surface of the mounting portion 211. The grooves 300 are arranged at intervals to form heating ribs 400 between adjacent grooves 300, and the heating ribs 400 are in contact with the heating pipe 220 or the bottom of the kettle body 100. The heating ribs 400 are radially disposed outward around the center of the heat conductive plate 210, and the width of the heating ribs 400 is gradually increased from the edge of the heat conductive plate 210 to the center of the heat conductive plate 210.

The lower surface of the mounting part 211 is connected with the heating pipe 220, and the upper surface is connected with the bottom of the kettle body 100. After the groove 300 is formed on the upper surface of the heat conducting plate 210, the heat pipe 220 contacts the mounting portion 211 of the heat conducting plate 210 and transfers heat, and a portion of heat flows from the lower surface of the heat conducting plate 210 to the bottom surface of the groove 300 in the thickness direction of the mounting portion 211 of the heat conducting plate 210, and since the bottom surface of the groove 300 cannot contact the bottom of the kettle body 100 and transfer heat, more heat flows in the heat conducting plate 210 from the mounting portion 211 in the radial direction.

As shown in fig. 3, it is understood that the grooves 300 are tapered grooves radially outwardly around the center of the heat-conducting plate 210, the width of the outer ends of the grooves 300 near the edge of the heat-conducting plate 210 is greater than the width of the inner ends of the grooves 300 near the center of the heat-conducting plate 210, and the adjacent grooves 300 are spaced apart such that the width of the heating ribs 400 gradually increases from the edge of the heat-conducting plate 210 to the center of the heat-conducting plate 210. Preferably, the depth of the groove 300 is greater than or equal to 0.2mm and is set to be less than the thickness of the thermal conductive disk 210.

In this way, by disposing the groove 300 on the upper surface of the mounting portion 211, the lower surface of the mounting portion 211 is sufficiently contacted with the heating pipe 220, and the efficiency of heat transfer between the heating pipe 220 and the heat conducting disc 210 is improved. The grooves 300 are arranged at intervals to form the heating ribs 400 contacting with the heating pipe 220 or the bottom of the kettle body 100 between the adjacent grooves 300, so that when the grooves 300 reduce the flowing amount of heat generated by the heating pipe 220 in the thickness direction of the mounting part 211, part of the heat can be transferred to the heat conducting disc 210 along the heating ribs 400, and the heating efficiency of the heat conducting disc 210 is ensured. Through outwards becoming radial setting around the center of heat conduction dish 210 with heating muscle 400, the width of heating muscle 400 is crescent from heat conduction dish 210 edge to heat conduction dish 210 center for more heat can follow heating muscle 400 in the heating process and flow to the slower heat conduction dish 210 center department of intensification from the faster heat conduction dish 210 edge of intensification, improves heat conduction dish 210 temperature uniformity, and the noise that the bubble burst produced when further reducing the heating.

Preferably, as shown in fig. 3, the groove 300 is disposed to communicate with the outside near the edge of the heat conductive plate 210. Thus, the groove 300 is communicated with the outside near the edge of the heat conducting disc 210, so that air trapping in the groove 300 is prevented when the bottom of the kettle body 100 or the heating pipe 220 is welded with the heat conducting disc 210, and the reliability of connection between the heat conducting disc 210 and the kettle body 100 and the heating pipe 220 is improved.

In another embodiment, as shown in fig. 4, a groove 300 may be further provided on a lower surface of the mounting portion 211. It can be understood that when the groove 300 is formed on the lower surface of the mounting portion 211, the heating tube 220 contacts the heating rib 400 formed between the grooves 300, and when the heating tube 220 is heated, the heat flows into the heating rib 400 and is dispersed along the heat conducting plate 210, and then heats the bottom of the kettle body 100 through the upper surface of the heat conducting plate 210.

Example two

As shown in fig. 5 to 6, the present embodiment is different from the first embodiment in that a surface of the mounting portion 211 facing away from the groove 300 is provided with a first heat conduction boss 310 along a circumferential direction of the heating tube 220, and the first heat conduction boss 310 is used for contacting with the heating tube 220 or the bottom of the kettle body 100. Preferably, the first heat conduction bosses 310 are arranged at intervals.

It can be understood that, when the groove 300 is disposed on the upper surface of the mounting portion 211, the first heat conducting boss 310 is disposed on the lower surface of the mounting portion 211, the heat generated by the heating pipe 220 is firstly transferred to the first heat conducting boss 310, and after the heat is dispersed by the first heat conducting boss 310, the heat is transferred from the heat conducting disc 210 to the bottom of the kettle body 100 to heat the water, so as to further improve the temperature uniformity on the heat conducting disc 210 and reduce the noise generated during heating; when the groove 300 is disposed on the lower surface of the mounting portion 211, the first heat conduction boss 310 may be disposed on the upper surface of the mounting portion 211, and at this time, the top of the first heat conduction boss 310 contacts with the bottom of the kettle body 100, and heat generated by the heating pipe 220 is firstly transferred to the heating rib 400 and dispersed by the heat conduction plate 210, and then transferred to the bottom of the kettle body 100 by the first heat conduction boss 310 to heat the water.

So, through set up first heat conduction boss 310 along the circumference of heating pipe 220 on the surface that mounting portion 211 deviates from recess 300, first heat conduction boss 310 is used for contacting with heating pipe 220 or kettle body 100 bottom for recess 300 and first heat conduction boss 310 are respectively towards kettle body 100 bottom and heating pipe 220, when reducing the heat along the vertical transmission of mounting portion 211, guarantee the heat along the radial transmission of heat conduction dish 210, have improved the heat transfer efficiency of heat conduction dish 210 with heating pipe 220. By arranging a plurality of first heat conduction bosses 310 at intervals, the plurality of first heat conduction bosses 310 are in contact with the heating pipe 220 or the bottom of the kettle body 100 at the same time and transfer heat, so that the heat transfer efficiency of the heat conduction plate 210 is improved.

Preferably, the groove 300 and the first heat conduction boss 310 are integrally formed by punching, so that the first heat conduction boss 310 is disposed corresponding to the groove 300.

It can be understood that the shape of the first heat conducting boss 310 may be set corresponding to the shape of the groove 300, so that the first heat conducting boss 310 may be naturally formed when the groove 300 is punched, and the groove 300 and the first heat conducting boss 310 are formed by one-time punching, which is low in processing cost.

EXAMPLE III

In this embodiment, a plurality of the grooves 300 are arranged at intervals to form the heating ribs 400 between adjacent grooves 300, and the heating ribs 400 contact with the heating tube 220 or the bottom of the kettle body 100. Specifically, as shown in fig. 7, in one embodiment, the groove 300 may be a hexagonal groove, such that a plurality of hexagonal grooves are uniformly distributed in the mounting portion 211 at intervals and form a honeycomb structure; alternatively, as shown in fig. 8, in another embodiment, the recess 300 may be a circular groove, such that a plurality of circular grooves are uniformly spaced in the mounting portion 211 and form a porous structure.

Preferably, the interval between the adjacent two grooves 300 is set to be in the range of 0.5mm to 10 mm.

In still another embodiment of the water boiler, as shown in fig. 9, the heating ribs 400 between the adjacent grooves 300 are grooved to communicate the adjacent grooves 300 with each other, and the grooves 300 near the edge of the heat conductive plate 210 communicate with the outside. The grooves 300 adjacent to each other are communicated with each other through the grooves 400 of the heating ribs between the adjacent grooves 300, and the grooves 300 close to the edges of the heat conducting discs 210 are communicated with the outside, so that the grooves 300 are communicated with the outside after being communicated with each other, the air trapping inside the grooves 300 is prevented when the bottom of the kettle body 100 or the heating pipe 220 is welded with the heat conducting discs 210, and the connection reliability of the heat conducting discs 210, the kettle body 100 and the heating pipe 220 is improved.

Example four

As shown in fig. 10, in the present embodiment, the groove 300 is an arc-shaped groove disposed around the center of the heat conducting plate 210, a plurality of second heat conducting bosses 320 are disposed in the groove, and the top surfaces of the second heat conducting bosses 320 are flush with the top surface of the heat conducting plate 210.

The length of the arc-shaped groove is set to correspond to the length of the heating pipe 220 so that the arc-shaped groove completely covers the corresponding region of the heating pipe 220 within the mounting portion 211. The second heat conduction bosses 320 are preferably circular bosses and are evenly spaced around the center of the heat conduction plate 210 in the arc-shaped slots.

So, through setting up the arc wall that recess 300 set up for encircleing heat conduction dish 210 center, be equipped with a plurality of second heat conduction bosss 320 in the recess, utilize arc wall and the dispersion heat of second heat conduction boss 320, prevent that the heat that heating pipe 220 produced from transmitting fast in installation department 211 thickness direction, improve the heat along the flow of the radial transmission of heat conduction dish 210 for heat conduction dish 210 temperature is even. In addition, the top surface of the second heat conduction boss 320 is flush with the top surface of the heat conduction plate 210, so that the second heat conduction boss 320 and the heat conduction plate 210 are simultaneously contacted with the bottom of the kettle body 100, and the uniformity of heat transfer of the heat conduction plate 210 is ensured.

Preferably, the second heat conductive protrusion 320 is disposed near the center of the heat conductive plate 210, and the heat transfer area is larger than that of the second heat conductive protrusion 320 disposed near the edge of the heat conductive plate 210.

It will be appreciated that a plurality of second thermally conductive bosses 320 may be evenly distributed around the thermally conductive plate 210 in a plurality of concentric rings, each ring being formed by a plurality of second thermally conductive bosses 320 at intervals. The second heat conduction boss 320 relatively close to the center of the heat conduction plate 210 has a larger heat transfer area in contact with the bottom of the kettle body 100, and the second heat conduction boss 320 relatively close to the edge of the heat conduction plate 210 has a smaller heat transfer area in contact with the bottom of the kettle body 100. Therefore, by arranging the second heat conduction boss 320 close to the center of the heat conduction plate 210, the heat transfer area is larger than that of the second heat conduction boss 320 close to the edge of the heat conduction plate 210, so that more heat is transferred to the central area close to the heat conduction plate 210 through the second heat conduction boss 320 with larger heat transfer area, the integral temperature uniformity of the heat conduction plate 210 is improved, and the noise is further reduced.
